Description

  The present invention relates to a fruit and vegetable picking body on which fruit vegetables can be placed during automatic selection of fruit and vegetables, and a fruit and vegetable picking apparatus equipped with the fruit and vegetable picking body.

  Tomatoes, oranges, onions, kiwis, round fruits and vegetables (round fruits and vegetables) such as eggplants, eggplants and peppers (long fruits) Various fruits and vegetables such as strawberry and other perishable fruits are brought into the fruit selection area after harvesting, and the operator visually selects the presence or absence of scratches, coloring, deformation, etc. at the fruit selection area, and the shape, size, sugar content, etc. (Equal class) is measured with a measuring instrument, discriminated by equal class based on the measurement result, fruit vegetables after the classification are classified by equal class, and the sorted fruit vegetables are boxed and shipped.

  For the selection of fruit vegetables, an automatic fruit vegetable sorting apparatus is used. As an automatic vegetable vegetable sorting device, an automatic vegetable vegetable sorting device previously developed by the present applicant is known (for example, Patent Documents 1 to 5).

  The conventional fruit and vegetable automatic sorting device has many fruit and vegetables mounted on an endless chain, and the fruit and vegetables loaded automatically travels along the rotation of the endless chain and automatically transports the fruit and vegetables on the fruit and vegetables. can do. The fruits and vegetables that are placed on the fruits and vegetables are measured in shape and size during the transport, and are determined to be in the same standard class as the standard. Depending on the situation, it is sent out to the side of the fruit vegetable running direction so that it can be sorted by equal class.

  The fruit vegetable carrier is a belt conveyor type in which a belt is rotatably wound around a frame that can be attached to an endless chain. During conveyance, the belt rotates to the side in the conveyance direction according to the equal class discrimination result, and above the belt The fruits and vegetables are sent out in the belt rotation direction (sorted by equal class), and the belt reversely rotates and returns to the original position during feeding after feeding (after sorting).

[Fruit vegetables]
The fruit and vegetables mounting body of the present invention has the following effects depending on its configuration.
(1) Since two belts are provided so that the widthwise outer side of the upper running part of the belt is inclined upward from the inside, one fruit vegetable is placed across the upper running part of the two belts. The two belts are supported at two points and are stable, and are difficult to roll sideways in the conveying direction. In the case of two-point support, the contact area of the fruit vegetables to the belt is narrowed, so that the fruit vegetables are less likely to be scratched by contact with the belt.
(2) Since at least both outer belts of the three or more belts are provided so that the lateral width direction outer side of the upper running part of the belt is inclined upward from the inner side, one fruit vegetable is formed on both outer belts, The belt is placed on the inner belt of the belt, and is supported by these belts (supported by three points in the case of three belts) and stabilized. It becomes difficult to roll. Also in the case of the support, since the contact area of the fruit vegetables to the belt is narrowed, the fruit vegetables are less likely to be scratched by contact with the belt. (3) The fruit vegetables placement part is straddled across all or part of the two or more belts. When it is provided, it becomes easy to place fruit and vegetables on the fruit and vegetables mounting part. Since fruits and vegetables are distributed and supported by two or more belts, the fruits and vegetables on the belt are placed on the running part of a single horizontal or substantially horizontal belt. The contact area is reduced, and scratches due to contact with the belt are less likely to occur.
(4) When a backrest that moves together with the belt is provided behind the fruit vegetable placement section, the backrest can be placed on the fruit vegetable placement section using the backrest as a guide for positioning, so it becomes easier to place the fruit vegetables on the fruit vegetable placement section. . In addition, fruits and vegetables can be placed in a row or almost in a row on a large number of fruits and vegetables mounted on an endless chain, and the placed fruits and vegetables can be supported from the rear, so that the fruits and vegetables are misaligned during transport. This is a measuring instrument provided above the vegetable transporter in the measurement / discrimination area so that it can be transported in a single row or almost in a single row and sent to the measurement / discrimination unit. Can be measured accurately, and the measurement accuracy is improved. In addition, when it is difficult to smoothly transfer the delivered fruit vegetables to the pool conveyor or the relay tool, the fruit vegetables are pushed with a backrest, so that the transfer is ensured.
(5) When the belt is provided obliquely rearward in the running direction of the endless chain so that the fruit vegetables can be sent obliquely backward in the running direction of the endless chain, the inertia in the transport direction of the delivered fruit vegetables is reduced. Fruit vegetables sent out to the pool conveyor or relay tool are less likely to roll.

The fruit vegetable automatic sorting apparatus of the present invention has the following effects depending on its configuration.
(1) Since the fruit and vegetables mounting body of the present invention capable of producing the above effects is provided, the effects of the fruit and vegetables mounting body are exhibited.
(2) When at least the number of pool conveyors in the traveling direction of the endless chain is provided for each equal class, it is possible to reliably sort the fruits and vegetables determined by the equal class according to the equal class.
(3) When the pool conveyor is rotated intermittently each time the fruit and vegetables are sent to secure the acceptance area of the fruit and vegetables, the fruit and vegetables that are sent out later collide with the fruit and vegetables that are sent out and pooled on the pool conveyor. And will not be damaged by collision.
(4) Fruit vegetables can be drawn onto the belt by rotation of the belt of the pool conveyor, so that the fruit vegetables can be taken over reliably.
(5) When a discrimination button for inputting the result of visual discrimination is provided, scratches and colors on the part that cannot be measured by the measuring instrument (bottom side of fruit vegetables) are also considered as items for class classification, so high accuracy This makes it possible to discriminate between equal classes.
(6) If the button traveling body to which the discrimination button is attached is provided in the section from the supply area to the front of the sorting area, the button traveling body does not interfere with the sorting of the fruit vegetables in the sorting area.

As an example, the guide groove 21 shown in FIG. 11 is formed by forming a straight guide 21a and an oblique guide 21b provided obliquely with respect to the linear guide 21a on a flat plate material 23. The slide pin 7 of the fruit vegetable mounting body 1 moves along the rectilinear guide 21a. When the fruit vegetable mounting body 1 on which the fruit vegetables A to be sorted arrives, the switching lever 34 closes the rectilinear guide 21a and opens the oblique guide 21b. The slide pin 7 is guided by the oblique guide 21b and moves to the side.

  5A and 5B, when the slide pin 7 is provided in the lower traveling portion 5y of the belt 5, the movement of the slide pin 7 causes the belt 5 interlocked with the slide pin 7 to The fruits and vegetables A placed on the belt 5 of the fruits and vegetables placing body 1 are sent out to the pool conveyor 25 by rotating in the moving direction (conveyance direction side: pool conveyor 25 side). The switching lever 34 is switched by a rotary solenoid (not shown) provided therebelow, and the rotary solenoid is operated in response to a determination signal in the measurement / discrimination area. In addition, when using the fruit and vegetables mounting body 1 in which the slide pin 7 was provided in the upper surface 5x of the belt 5 like FIG. 6 (a) (b), the direction of the guide groove 21 in FIG. The direction is reversed.

  At the tip of the sorting area, a return guide (not shown) is provided for returning the slide pin 7 moved along the oblique guide 21b to the straight guide 21a, and the slide pin 7 is moved to the straight guide 21a along the return guide. When the guide pin 7 is returned, the belt 5 and the backrest 11 to which the guide pin 7 is connected return to the original position as the guide pin 7 moves. The belt 5 and the backrest 11 return to their original positions before the fruit and vegetable mount 1 returns to the supply area, and when the fruit and vegetable mount 1 reaches the supply area, a large number of fruit and vegetable mounts 1 are placed. The parts 20 are arranged in a line. By aligning the fruits and vegetables mounting part 20 in a line until the fruit and vegetables mounting body 1 reaches the supply area, the fruits and vegetables A placed on one fruit and vegetable mounting part 20 of the fruit and vegetables mounting body are aligned in a line. In this state, it can be sent to the measuring instrument 31 side, and high-precision measurement / discrimination becomes possible.

[Pool conveyor]
The said pool conveyor 25 takes over the fruit vegetables A sent out from the fruit and vegetables mounting body 1 which reached | attained the sorting area. As an example, the pool conveyor 25 shown in FIG. 10 is of a belt conveyor type in which a flat belt is circulated around the outer periphery of rollers arranged at intervals. The pool conveyor 25 is long and wide enough to pool a large number of fruit vegetables A. The pool conveyor 25 rotates (intermittently rotates) each time the fruit vegetable A is sent out from the fruit vegetable carrier 1, and the fruit vegetables A are pooled on the upper running portion 25a of the pool conveyor 25 (FIGS. 5A and 5B). I can do it.

  In this embodiment, the pool conveyor 25 is arranged in parallel at two or more locations on the side of the fruit and vegetable carrier 30 so as to be orthogonal to the fruit and vegetable carrier 30. The pool conveyors 25 are provided in at least the number of the equal classes of the fruit vegetables A, and the fruit vegetables A can be sent out to the respective pool conveyors 25 by the equal classes. The pool conveyor 25 can also be disposed diagonally backward or diagonally forward with respect to the transport direction of the fruit vegetable transport body 30. In this case, if a gap wider than the fruit vegetables A is formed between the fruit vegetable transport body 30 and the pool conveyor 25, the fruit vegetables A fall into the gap, so that the relay tool 26 (FIGS. 12A and 12B) does not fall. ) Is desirable. Only one pool conveyor 25 can be provided in one place, or a plurality of pool conveyors 25 can be provided. It is desirable to secure a work space that is at least wide enough for an operator to perform boxing work on the side of the pool conveyor 25.

  It is not necessary for all the pool conveyors 25 to have the same belt width, length, etc., and the pool conveyors 25 that take over the large number of equal class fruits and vegetables A can be increased in number, width, and length. If it is made longer, many fruit vegetables A can be reliably pooled. Even if the number of the pool conveyors 25 that take over the fruit vegetables A of the same class with a small number of the fruit vegetables A is reduced, the width is reduced, or the width is reduced, the fruit vegetables A can be reliably pooled.

  The pool conveyor 25 can be rotated at all times. However, when the fruit and vegetables A are not sent, the pool conveyor 25 is temporarily stopped and kept waiting, and when the fruit and vegetables A is fed from the fruit and vegetables mounting body 1, it is rotated by one fruit and vegetables. Thus, it can be controlled so that a space for the fruit vegetables A is secured. The rotation control of the pool conveyor 25 is also performed by the control means based on the determination result in the measurement / discrimination area. Each time the fruit vegetable A is fed, it is rotated by one fruit vegetable, so that both the feeding by the fruit vegetable mounting body 1 and the drawing (pulling) by the pool conveyor 25 work on the fruit vegetable A, and the fruit vegetable A is smoothly fed out. To be done.

[Fruit vegetables measurement, discrimination button]
The automatic measurement by the measuring instrument 31 is generally performed by irradiating the fruit vegetable A with measurement light from above or from the side of the fruit vegetable A. Therefore, scratches, deformation, color unevenness, etc. on the bottom surface of the fruit vegetable A are measured. I can't. In the present invention, scratches, deformations, color unevenness and the like on the bottom side of the fruit vegetable A that cannot be automatically measured by the measuring instrument 31 are visually determined, and the determination result can be input with the determination button (FIG. 10) 35. This determination is made by placing the fruits A on the fruits and vegetables mounting part 20 of the fruits and vegetables 1 by visually confirming the scratches, deformations, color unevenness, etc. on the bottom side of the fruits A. . The worker who has visually discriminated can operate the discriminating button 35 in accordance with the discriminating result to input the discriminating result when placing the fruit vegetable A on the fruit vegetable placing unit 20 or before placing it on the fruit vegetable placing unit 20. It is. The discrimination buttons 35 of this embodiment are provided as a set of two, and four patterns can be discriminated per group (four patterns of pressing only one, pressing both, neither pressing).

  The discriminating button 35 shown in FIG. 10 is attached to an endless chain (hereinafter referred to as “button traveling body”) 36 for a button such as an endless rotating chain or an endless rotating timing belt. The button traveling body 36 is provided on the side of the fruit and vegetable transport body 30 and is provided in a section from the fruit and vegetables mounting area to the front of the sorting area, and is configured to travel in a rotating manner in the section. The reason why the button traveling body 36 is rotated in front of the sorting area is to prevent the determination button 35 from getting in the way when the fruit vegetables A on the fruit and vegetables mounting body 1 are sent to the pool conveyor 25. The button traveling body 36 has a traveling speed that is the same as the traveling speed of the fruit and vegetable carrier 30, and in the traveling state, one set of determination buttons 35 is parallel to one set of belts.

  When each discrimination button 35 is not operated (not pressed), fruit vegetables A are in class A, when only one discrimination button 35a is pressed, class B, and only the other discrimination button 35b is pressed. The relationship between the operation of the discriminating button 35 and the grade is determined in advance, such as class C, when both discriminating buttons 35a and 35b are pressed, such as class D. Under this relationship, when the bottom surface state of the fruit vegetable A to be placed on the fruit vegetable mounting body 1 is good, it is visually distinguished from class A and no discrimination button 35 is pressed, and when the bottom surface state is slightly bad, it is visually distinguished from class B. Then, the left discriminating button 35a is pressed. If the bottom surface is significantly deformed, it is visually discriminated as C class and the right discriminating button 35b is pushed. , 35b, and the respective visual discrimination results are input.

  The fruit and vegetables A that have been visually discriminated are conveyed by the fruit and vegetable conveying body 30 and the shape, size, and the like are automatically measured by the measuring device 31 in the measurement / discrimination area. The automatic measurement result is comprehensively determined in accordance with the visual determination result input from the determination button 35 as described above. For example, fruit vegetables A that are determined to be class A by visual discrimination are determined to be S size by automatic measurement, and are classified as class A S size (AS). (AM), A class L size (AL) when automatically determined as L size, A class LL size (ALL) when automatically determined as LL size, etc. Classification is made.

[Fruit vegetables]
The fruit and vegetables mounting body of the present invention has the following effects depending on its configuration.
(1) Since two belts are provided so that the widthwise outer side of the upper running part of the belt is inclined upward from the inside, one fruit vegetable is placed across the upper running part of the two belts. The two belts are supported at two points and are stable, and are difficult to roll sideways in the conveying direction. In the case of two-point support, the contact area of the fruit vegetables to the belt is narrowed, so that the fruit vegetables are less likely to be scratched by contact with the belt.
(2) Since at least both outer belts of the three or more belts are provided so that the lateral width direction outer side of the upper running part of the belt is inclined upward from the inner side, one fruit vegetable is formed on both outer belts, The belt is placed on the inner belt of the belt, and is supported by these belts (supported by three points in the case of three belts) and stabilized. It becomes difficult to roll. Also in the case of the support, since the contact area of the fruit vegetables to the belt is narrowed, the fruit vegetables are less likely to be scratched by contact with the belt. (3) The fruit vegetables placement part is straddled across all or part of the two or more belts. When it is provided, it becomes easy to place fruit and vegetables on the fruit and vegetables mounting part. Since fruits and vegetables are distributed and supported by two or more belts, the fruits and vegetables on the belt are placed on the running part of a single horizontal or substantially horizontal belt. The contact area is reduced, and scratches due to contact with the belt are less likely to occur.
(4) When a backrest that moves together with the belt is provided behind the fruit vegetable placement section, the backrest can be placed on the fruit vegetable placement section using the backrest as a guide for positioning, so it becomes easier to place the fruit vegetables on the fruit vegetable placement section. . In addition, fruits and vegetables can be placed in a row or almost in a row on a large number of fruits and vegetables mounted on an endless chain, and the placed fruits and vegetables can be supported from the rear, so that the fruits and vegetables are misaligned during transport. This is a measuring instrument provided above the vegetable transporter in the measurement / discrimination area so that it can be transported in a single row or almost in a single row and sent to the measurement / discrimination unit. Can be measured accurately, and the measurement accuracy is improved. In addition, when it is difficult to smoothly transfer the delivered fruit vegetables to the pool conveyor or the relay tool, the fruit vegetables are pushed with a backrest, so that the transfer is ensured.
(5) When the belt is provided obliquely rearward in the running direction of the endless chain so that the fruit vegetables can be sent obliquely backward in the running direction of the endless chain, the inertia in the transport direction of the delivered fruit vegetables is reduced. Fruit vegetables sent out to the pool conveyor or relay tool are less likely to roll.

The fruit vegetable automatic sorting apparatus has the following effects depending on its configuration.
(1) Since the fruit and vegetables mounting body of the present invention capable of producing the above effects is provided, the effects of the fruit and vegetables mounting body are exhibited.
(2) When at least the number of pool conveyors in the traveling direction of the endless chain is provided for each equal class, it is possible to reliably sort the fruits and vegetables determined by the equal class according to the equal class.
(3) When the pool conveyor is rotated intermittently each time the fruit and vegetables are sent to secure the acceptance area of the fruit and vegetables, the fruit and vegetables that are sent out later collide with the fruit and vegetables that are sent out and pooled on the pool conveyor. And will not be damaged by collision.
(4) Fruit vegetables can be drawn onto the belt by rotation of the belt of the pool conveyor, so that the fruit vegetables can be taken over reliably.
(5) When a discrimination button for inputting the result of visual discrimination is provided, scratches and colors on the part that cannot be measured by the measuring instrument (bottom side of fruit vegetables) are also considered as items for class classification, so high accuracy This makes it possible to discriminate between equal classes.
(6) If the button traveling body to which the discrimination button is attached is provided in the section from the supply area to the front of the sorting area, the button traveling body does not interfere with the sorting of the fruit vegetables in the sorting area.

(Embodiment 1 for fruit and vegetables)
An example of the fruit and vegetables mounting body 1 of the present invention will be described with reference to the drawings. The fruit and vegetables mounting body 1 of the present invention is of a belt conveyor type in which a belt 5 is circulated around a frame 3 so as to be reciprocally rotatable. The frame 3 is attached to an endless chain 2 (FIG. 10), and the endless chain 2 travels. Accordingly, it moves in the traveling direction and conveys the fruit vegetables A placed on the upper traveling portion 5x of the belt 5 (FIGS. 5A and 5B and FIGS. 6A and 6B) in the traveling direction. It is possible. As an example, the fruit and vegetables mounting body 1 shown in FIG. 1 has a frame provided with three belts 5a to 5c.

[Frame of fruits and vegetables]
As shown in FIG. 2, the frame 3 includes a base portion 3a having a polygonal shape in plan view and fixed pieces 3b projecting downward at both ends in the width direction of the base portion 3a. In the base portion 3a, an elongated hole 6 (FIG. 3B) is opened in the longitudinal direction, and a slide pin 7 (FIG. 3B) protrudes from the elongated hole 6 to below the base portion 3a. I have to do it. Two fixing holes 3c are opened in each fixing piece 3b so that a stopper can be inserted and fixed when fixing to the endless chain 2 (FIG. 10). Four support portions 9 for holding the rotating roller 10 (FIG. 1) are erected on the base portion 3a. For convenience of explanation, in the present application, the four support portions 9 are referred to as a first support portion 9a, a second support portion 9b, a third support portion 9c, and a fourth support portion 9d in order from the left in the drawing.

  As shown in FIG. 2, each of the first support portion 9a to the fourth support portion 9d includes upright portions 12a to 12d and inclined portions 13a to 13d. Between the inclined portion 13a of the first support portion 9a and the inclined portion 13b of the second support portion 9b, one at each of the longitudinal ends (two in total) ("first roller" for convenience of explanation) 10a and 10b are pivotally supported. When the first roller 10a, 10b is viewed from the front, one end of the support shaft is supported by the inclined portion 13a of the first support portion 9a and the other end is supported by the inclined portion 13b of the second support portion 9b. It is supported in the state inclined diagonally inward.

[Rotating roller for fruit and vegetables]
Between the upright portion 12b of the second support portion 9b and the upright portion 12c of the third support portion 9c, there are two stages (four in total) on each of the longitudinal ends thereof (for convenience of explanation, “second roller”). 10c to 10f are pivotally supported. The second rollers 10c to 10f have one end of the support shaft supported by the upright part 12b of the second support part 9b and the other end supported by the upright part 12c of the third support part 9c. In this way, it is supported in a state of being parallel or substantially parallel to the base portion 3a of the frame 3.

  Between the inclined portion 13c of the third support portion 9c and the inclined portion 13d of the fourth support portion 9d, one at each of the longitudinal ends (two in total) (for convenience of explanation, “third roller”). 10g and 10h are pivotally supported. When the third rollers 10g and 10h are viewed from the front, one end of the support shaft is supported by the inclined portion 13c of the third support portion 9c and the other end is supported by the inclined portion 13d of the fourth support portion 9d. It is supported in the state inclined diagonally inward.

  Among the rotating rollers 10a to 10h, the rollers 10a, 10c, 10d, and 10g on the front side in the feeding direction of the conveying belt are projected outward from the fixed piece 3b of the frame 3. Thus, the rollers 10 a, 10 c, 10 d, 10 g on the front side in the feeding direction protrude outside the fixed piece 3 b of the frame 3, so The gap can be minimized, and it is possible to prevent the fruit A from being damaged by fitting the fruit A in the gap between the leading end of the fruit and vegetables mounting body 1 and the pool conveyor 25.

[Fruit vegetable belt]
An endless belt (referred to as “first belt” for convenience of explanation) 5a is provided on the outer circumference of the first rollers 10a and 10b, and an endless belt (for convenience of explanation on the outer circumference of the second rollers 10c to 10f. An endless belt (referred to as “third belt” for convenience of explanation) 5c is circulated around the outer periphery of the third rollers 10g and 10h. The first belt 5 a to the third belt 5 c are reciprocating belts 5. The term “endless” as used herein refers not only to the case where the belt 5 itself is circulated in an annular shape, but also an end portion of the belt 5 connected by a connecting means to form an annular shape, or a plurality of belt pieces. It is meant to include those that are connected by a connecting means to form a ring.

  The first belt 5a to the third belt 5c are wound with tension, and the upper traveling portion 5x (FIGS. 5A and 5B, FIGS. 6A and 6B) and the lower traveling portion 5y, respectively. Is not bent unnecessarily. Here, the upper traveling portion 5x and the lower traveling portion 5y are relative concepts, and if the upper traveling portion 5x above the rotating roller 10 goes around the lower side of the rotating roller 10, the corresponding portion becomes the lower traveling portion 5y. If the lower traveling portion 5y below the rotating roller 10 goes around the upper side of the rotating roller 10, the portion becomes the upper traveling portion 5x. The belt 5 preferably has a cushioning property from the viewpoint of preventing damage to fruit vegetables. In addition, in order to make it easy to wipe away belt stains and other stains due to soaking of fruit juice, materials that do not absorb moisture, such as those coated on both front and back surfaces or one surface of an elastic material such as sponge with a non-water-absorbing material, etc. The thing etc. which bonded together are preferable.

[Looking backward]
When the frame 3 is attached to the endless chain 2, the rotation roller 10 is arranged so that the front side (the rotation rollers 10 a, 10 c, 10 d, and 10 g side) of the belt 5 circulated by the rotation rollers 10 is the endless chain 2. It is arranged so as to be obliquely rearward with respect to the traveling direction, and the fruits A can be sent out obliquely backward in the traveling direction of the endless chain 2 by the rotation of the belt 5. By enabling the fruit vegetables A to be sent obliquely backward in the traveling direction of the endless chain 2, the inertial force acting in the traveling direction of the endless chain 1 can be reduced, and the fruit vegetables A can be prevented from rolling during the feeding.

When the guide pin 7 is returned, the belt 5 and the backrest 11 to which the guide pin 7 is connected return to the original position as the guide pin 7 moves. The belt 5 and the backrest 11 return to their original positions before the fruit and vegetable mount 1 returns to the supply area, and when the fruit and vegetable mount 1 reaches the supply area, a large number of fruit and vegetable mounts 1 are placed. The parts 20 are arranged in a line. By aligning the fruits and vegetables mounting part 20 in a line until the fruit and vegetables mounting body 1 reaches the supply area, the fruits and vegetables A placed on one fruit and vegetable mounting part 20 of the fruit and vegetables mounting body are aligned in a line. In this state, it can be sent to the measuring instrument 31 side, and high-precision measurement / discrimination becomes possible.

[Pool conveyor]
The said pool conveyor 25 takes over the fruit vegetables A sent out from the fruit and vegetables mounting body 1 which reached | attained the sorting area. As an example, the pool conveyor 25 shown in FIG. 10 is of a belt conveyor type in which a flat belt is circulated around the outer periphery of rollers arranged at intervals. The pool conveyor 25 is long and wide enough to pool a large number of fruit vegetables A. The pool conveyor 25 rotates (intermittently rotates) each time the fruit vegetable A is sent out from the fruit vegetable carrier 1, and the fruit vegetables A are pooled on the upper running portion 25a of the pool conveyor 25 (FIGS. 5A and 5B). I can do it.

In this fruit vegetable automatic sorting apparatus , the pool conveyor 25 is disposed in parallel at two or more locations on the side of the fruit vegetable carrier 30 so as to be orthogonal to the fruit vegetable carrier 30. The pool conveyors 25 are provided in at least the number of the equal classes of the fruit vegetables A, and the fruit vegetables A can be sent out to the respective pool conveyors 25 by the equal classes. The pool conveyor 25 can also be disposed diagonally backward or diagonally forward with respect to the transport direction of the fruit vegetable transport body 30. In this case, if a gap wider than the fruit vegetables A is formed between the fruit vegetable transport body 30 and the pool conveyor 25, the fruit vegetables A fall into the gap, so that the relay tool 26 (FIGS. 12A and 12B) does not fall. ) Is desirable. Only one pool conveyor 25 can be provided in one place, or a plurality of pool conveyors 25 can be provided. It is desirable to secure a work space that is at least wide enough for an operator to perform boxing work on the side of the pool conveyor 25.

  It is not necessary for all the pool conveyors 25 to have the same belt width, length, etc., and the pool conveyors 25 that take over the large number of equal class fruits and vegetables A can be increased in number, width, and length. If it is made longer, many fruit vegetables A can be reliably pooled. Even if the number of the pool conveyors 25 that take over the fruit vegetables A of the same class with a small number of the fruit vegetables A is reduced, the width is reduced, or the width is reduced, the fruit vegetables A can be reliably pooled.

  The pool conveyor 25 can be rotated at all times. However, when the fruit and vegetables A are not sent, the pool conveyor 25 is temporarily stopped and kept waiting, and when the fruit and vegetables A is fed from the fruit and vegetables mounting body 1, it is rotated by one fruit and vegetables. Thus, it can be controlled so that a space for the fruit vegetables A is secured. The rotation control of the pool conveyor 25 is also performed by the control means based on the determination result in the measurement / discrimination area. Each time the fruit vegetable A is fed, it is rotated by one fruit vegetable, so that both the feeding by the fruit vegetable mounting body 1 and the drawing (pulling) by the pool conveyor 25 work on the fruit vegetable A, and the fruit vegetable A is smoothly fed out. To be done.

[Fruit vegetables measurement, discrimination button]
The automatic measurement by the measuring instrument 31 is generally performed by irradiating the fruit vegetable A with measurement light from above or from the side of the fruit vegetable A. Therefore, scratches, deformation, color unevenness, etc. on the bottom surface of the fruit vegetable A are measured. I can't. In this fruit vegetable automatic sorting device , scratches, deformations, color unevenness, etc. on the bottom side of the fruit vegetable A that cannot be automatically measured by the measuring instrument 31 are visually discriminated, and the discrimination result (FIG. 10) 35 can be input by the discrimination button (FIG. 10). is there. This determination is made by placing the fruits A on the fruits and vegetables mounting part 20 of the fruits and vegetables 1 by visually confirming the scratches, deformations, color unevenness, etc. on the bottom side of the fruits A. . The worker who has visually discriminated can operate the discriminating button 35 in accordance with the discriminating result to input the discriminating result when placing the fruit vegetable A on the fruit vegetable placing unit 20 or before placing it on the fruit vegetable placing unit 20. It is. The discrimination buttons 35 of this embodiment are provided as a set of two, and four patterns can be discriminated per group (four patterns of pressing only one, pressing both, neither pressing).

  The discriminating button 35 shown in FIG. 10 is attached to an endless chain (hereinafter referred to as “button traveling body”) 36 for a button such as an endless rotating chain or an endless rotating timing belt. The button traveling body 36 is provided on the side of the fruit and vegetable transport body 30 and is provided in a section from the fruit and vegetables mounting area to the front of the sorting area, and is configured to travel in a rotating manner in the section. The reason why the button traveling body 36 is rotated in front of the sorting area is to prevent the determination button 35 from getting in the way when the fruit vegetables A on the fruit and vegetables mounting body 1 are sent to the pool conveyor 25. The button traveling body 36 has a traveling speed that is the same as the traveling speed of the fruit and vegetable carrier 30, and in the traveling state, one set of determination buttons 35 is parallel to one set of belts.

  When each discrimination button 35 is not operated (not pressed), fruit vegetables A are in class A, when only one discrimination button 35a is pressed, class B, and only the other discrimination button 35b is pressed. The relationship between the operation of the discriminating button 35 and the grade is determined in advance, such as class C, when both discriminating buttons 35a and 35b are pressed, such as class D. Under this relationship, when the bottom surface state of the fruit vegetable A to be placed on the fruit vegetable mounting body 1 is good, it is visually distinguished from class A and no discrimination button 35 is pressed, and when the bottom surface state is slightly bad, it is visually distinguished from class B. Then, the left discriminating button 35a is pressed. If the bottom surface is significantly deformed, it is visually discriminated as C class and the right discriminating button 35b is pushed. , 35b, and the respective visual discrimination results are input.

  The fruit and vegetables A that have been visually discriminated are conveyed by the fruit and vegetable conveying body 30 and the shape, size, and the like are automatically measured by the measuring device 31 in the measurement / discrimination area. The automatic measurement result is comprehensively determined in accordance with the visual determination result input from the determination button 35 as described above. For example, fruit vegetables A that are determined to be class A by visual discrimination are determined to be S size by automatic measurement, and are classified as class A S size (AS). (AM), A class L size (AL) when automatically determined as L size, A class LL size (ALL) when automatically determined as LL size, etc. Classification is made.

[Fruit vegetables automatic sorting device 2]
