FIG. 6 is a perspective view showing a case where the base unit 60 shown in FIG. 2 is viewed from the lower right side. As shown in FIG. 6, the base unit 60 includes a base 61, a slider 62, a sold-out actuator 63, and a sold-out detection switch 64.

The base 61 is a long member whose longitudinal direction is the front-back direction, which is formed by bending a sheet metal or the like. As shown in FIG. 7, such a base 61 is configured by integrally forming a base base portion 611, a base front end portion 612, and a base rear end portion 613.

The base base portion 611 is a flat plate-shaped portion extending along the front-rear direction, and both left and right side portions thereof are bent downward. The base base 611 is slightly shorter than the spiral 50 in the front-rear direction, and has a rectangular elongated hole 611a whose front-rear direction is the longitudinal direction at the front end thereof.

The base front end portion 612 is a portion continuously provided to the front end portion of the base base portion 611. The base front end portion 612 includes a front end inclined portion 612a, a front surface forming portion 612b, and a front end locking portion 612c.

The front end inclined portion 612a gradually inclines downward as it goes forward from the front end portion of the base 611. The front surface forming portion 612b extends downward from the extending end portion of the front end inclined portion 612a, then extends rearward, and further extends upward.

The front end locking portion 612c extends rearward from the extending end portion of the front surface forming portion 612b, and a locking protrusion 614 that projects downward in a substantially central region of the extending end portion in the left-right direction is provided. It is what is formed.

The base rear end portion 613 is a portion continuously provided to the rear end portion of the base base portion 611. The base rear end portion 613 includes a rear end fastening portion 613a, an upper support piece 613b, a right support piece 613c, and a left support piece 613d (see FIG. 2).

The rear end fastening portion 613a is a portion that extends upward from the central portion of the extending end portion of the portion that gradually inclines upward as it goes rearward from the rear end portion 51a of the base 611. A fastening hole 615 is formed in the rear end fastening portion 613a.

The upper support piece 613b is formed so as to project rearward from the upper edge of the rear end fastening portion 613a. The right support piece 613c is formed so as to project rearward from the right end edge portion of the rear end fastening portion 613a. The left support piece 613d is formed so as to project rearward from the left end edge portion of the rear end fastening portion 613a.

The base 61 having such a configuration extends along the front-rear direction (extending direction of the column case 30) so as to penetrate through the inside of the spiral 50, and the locking projection 614 of the base front end 612 is the column case. The front end 612 of the base is locked and supported by the column case 30 by entering the locking hole 33 formed in the front end portion of the column 30.

Further, in the base 61, the upper support piece 613b, the right support piece 613c, and the left support piece 613d at the base rear end portion 613 respectively face the outer peripheral surface of the second transmission shaft portion 443 of the transmission member 44, A fastening pin 70 (see FIG. 2) inserted through the fastening hole 615 of the rear end fastening portion 613a is screwed into a support member (not shown) inserted through the hollow portion 444 of the transmission member 44.

As a result, the base 61 can place a product that is constrained between the pitches of the spiral 50 on the upper surface of the base base 611.

By the way, the upper support piece 613b at the base rear end portion 613 of the base 61 is located on the front side of the rear end portion 51a of the spiral 50 when the spiral 50 is in a standby state before rotation, as shown in FIG. The rear end portion 51a overlaps with the rear end portion 51a when viewed from the front.

A regulation member 71 is detachably attached to the base 61. As shown in FIG. 9, the regulation member 71 is a long member whose longitudinal direction is the front-rear direction, and is formed by bending a steel plate or the like. In this regulating member 71, a bottom wall portion 711 that can be placed on the upper surface of the base base portion 611 and an upper wall portion 712 that extends upward from the right end edge portion of the bottom wall portion 711 are integrally formed. Is configured. An engaging portion 713 extending downward is formed at the front end portion of the upper wall portion 712, and an engaging hole 713a is formed in the engaging portion 713. Further, at the rear end of the bottom wall portion 711, an engaging piece 714 cut and raised so as to project downward is formed.

Such a restricting member 71 has an engaging hole 713a formed in the rear end portion 51 of the base 611, the engaging hole 713a being inserted through the engaging long hole 611b, and a front end portion of the right side portion 611c of the base 611. The engaging pin 72, which is inserted through the engaging hole 713a, is inserted into the matching hole 611d and screwed into the engaging hole 711a, so that the engaging pin 72 is attached to the right side portion 611c of the base 611. At this time, the bottom wall portion 711 is placed on the upper surface of the base base portion 611, and the upper wall portion 712 extends continuously upward from the right side portion 611c of the base base portion 611. Although the length of the upper wall portion 712 extends upward, the upper end portion of the upper wall portion 712 does not interfere with the spiral 50.

The restriction member 71 is attached to the right side portion 611c of the base 611, because the spiral 50 rotates clockwise when viewed from the front. That is, of the left and right ends of the base 61, the right end is one end on which a part of the spiral 50 located above the base 61 is displaced downward by the rotation of the spiral 50. Therefore, it is attached to the right side portion 611c. Therefore, when the spiral 50 rotates counterclockwise when viewed from the front, a part of the left and right ends of the base 61, which is located above the base 61, is partially rotated. Since the one end on the side that is displaced downward is the left end, the restriction member is attached to the left side. When the regulation member is attached to the left side portion, the regulation member has a form symmetrical with the regulation member 71.

The slider 62 is arranged on the lower surface side of the base 611 so as to be movable in the front-rear direction with respect to the base 61 by a slider mounting member (not shown) mounted on the base 61. Such a slider 62 is configured by integrally forming a slider base portion 621, a slider rear end portion 622, and a slider front end portion 623.

The slider base 621 is an elongated rod-shaped portion whose longitudinal direction is the front-back direction. The slider rear end portion 622 is a portion that is provided continuously to the rear end portion 51a of the slider base portion 621, and is a portion that extends downward from the rear end portion of the slider base portion 621.

As shown in FIG. 10, the slider front end portion 623 is a portion that is provided continuously to the front end portion of the slider base portion 621, and from the front end of the left extension portion 624 that extends leftward from the front end portion of the slider base portion 621. It extends so as to project toward the front. The front end surface 623a of the slider front end portion 623 is an inclined surface that gradually inclines upward as it goes forward.

The slider 62 having such a configuration is constantly biased rearward by the slider spring 625 provided between the left extension portion 624 which is the rear end portion of the slider front end portion 623 and the foremost slider mounting member. ing. As a result, in the slider 62, the slider rear end portion 622 contacts the lower portion of the front end surface (first end surface portion 443a, second end surface portion 443b, third end surface portion 443c) of the second transmission shaft portion 443 of the transmission member 44. (See Figure 6).

As described above, in the transmission member 44, since the first end surface portion 443a of the second transmission shaft portion 443 is located below in the standby state, the slider rear end portion 622 has the first end surface portion 443a in the standby state. Touches. Here, since the first end surface portion 443a is located furthest rearward than the second end surface portion 443b and the third end surface portion 443c, the slider 62 whose slider rear end portion 622 is in contact with this first end surface portion 443a is It has moved to the rearmost side.

The sold-out actuator 63 is provided on the lower surface side of the base base portion 611 and in front of the slider base portion 621. As shown in FIG. 11, the sold-out actuator 63 includes a shaft portion 631, a contact portion 632, an inclined extension portion 633, and an action portion 634.

The shaft-shaped portion 631 is a portion that projects in the left-right direction, and is axially supported by the actuator mounting member 66 mounted on the base base portion 611. As a result, the sold-out actuator 63 can swing about the central axis of the shaft-shaped portion 631.

The contact portion 632 is a portion that extends along the radially outer direction of the shaft-shaped portion 631, and faces the slider front end portion 623. The inclined extending portion 633 is an elongated portion formed in such a manner that it gradually inclines upward as it goes forward from the contact portion 632. The inclined extending portion 633 can pass through the long hole 611 a formed in the base base portion 611. The action portion 634 is a curved portion formed below the shaft portion 631 so as to project rightward.

The sold-out actuator 63 is provided in such a manner that the shaft-shaped portion 631 is wound, and the inclined extension portion 633 is always directed upward by the actuator spring 635 interposed between itself and the actuator mounting member 66. Being energized.

The sold-out detection switch 64 is supported by the actuator mounting member 66 so as to be located on the right side of the sold-out actuator 63, as shown in FIG. The sold-out detection switch 64 is provided with a sold-out contactor 641. The sold-out contactor 641 is urged by an urging means (not shown) to determine its standby posture. The sold-out detection switch 64 detects that there is a product when the sold-out contactor 641 is in a standby posture without being pressed. On the other hand, if the sold-out contact 641 is pressed against the acting portion 634 of the sold-out actuator 63 to displace against the urging force of the urging means, the sold-out detection switch 64 indicates “no product”. Detect. That is, the sold-out detection switch 64 is arranged at a position where the sold-out contact 641 can come into contact with the acting portion 634 of the sold-out actuator 63.

The wiring connected to the sold-out detection switch 64 is laid in such a manner as to pass through the hollow portion 444 by a supporting member that is inserted through the hollow portion 444 of the transmission member 44.

In such a base unit 60, as shown in FIG. 2, when the product is not constrained between at least the foremost pitches of the spiral 50, the sold-out actuator 63 uses the actuator spring 635 as shown in FIG. The inclined extending portion 633 passes through the long hole 611 a and moves to the upper region of the base 61 to be in the advancing posture. In this way, when the sold-out actuator 63 is in the advanced posture, the action portion 634 presses the sold-out contactor 641 so that the sold-out contactor 641 is displaced against the biasing force of the biasing means.

On the other hand, when the product is restrained between the foremost pitches, the sold-out actuator 63 causes the tilted extending portion 633 to be pressed by the product W as shown in FIG. It retreats from the above-mentioned advance attitude against it. As the sold-out actuator 63 retreats from the advanced posture in this way, the sold-out contactor 641 becomes in a free state, and is biased only by the biasing means without being pressed to a standby posture.

By the way, in the product storage device 20, the optimum spiral 50 is used from among a plurality of types having different pitches according to the size of the product to be stored. On the other hand, the sold-out actuator 63 and the sold-out detection switch 64 are common regardless of the type of the spiral 50 applied.

Therefore, the sold-out actuator 63 is installed at a position where the spiral 50 having the longest distance between the pitches can be pressed by the product between the front pitches.

Therefore, in the sold-out actuator 63, when the spiral 50 having a relatively small pitch length is used, not only the front pitch of the spiral 50 but also the second pitch from the front or the pitch from the front of the spiral 50. The inclined extension portion 633 may be pressed by the product restrained between the second pitches to move backward from the advanced posture. In other words, the sold-out actuator 63 may retreat from the advance position even when the product is not constrained between the frontmost pitches of the spiral 50 and the product is constrained during the second pitch from the front.

The product storage device 20 having the above configuration can dispense the product (front product) restrained between the front pitches as follows.

When the user selects a product in the product storage device 20 through the product selection means and carries out the subtraction process by holding the electronic money recording medium in a predetermined communication area, the product storage is carried out. In the device 20, the motor drives and the output gear 43 and the transmission member 44 rotate in the clockwise direction around the central axis when viewed from the front. That is, the spiral 50 also rotates clockwise.

When the transmission member 44 rotates in the clockwise direction when viewed from the front together with the output gear 43 in this manner, the slider rear end portion 622 that was in contact with the first end surface portion 443a of the second transmission shaft portion 443 in the standby state is After contacting the third end surface portion 443c of the second transmission shaft portion 443, it contacts the second end surface portion 443b. This causes the slider 62 to move forward against the biasing force of the slider spring 625.

When the slider 62 moves forward, as shown in FIG. 15, the slider front end 623 is located above the contact portion 632 of the sold-out actuator 63, and the sold-out actuator 63 is forcibly moved to the retracted state. Hold it.

Then, the spiral gear 50 is rotated by the rotation of the output gear 43 and the transmission member 44 due to the driving of the motor, whereby the product constrained between the pitches of the spiral 50 is carried out forward and constrained between the front pitches. Products will be paid out forward.

After that, when the slider rear end 622 that slidably contacts the second end surface 443b of the second transmission shaft 443 contacts the third end surface 443c and the output gear 43 and the transmission member 44 make one rotation, the motor is driven. Stopping and payment of the front product ends. Then, as shown in FIG. 16, the slider 62 is biased by the slider spring 625 and moves rearward, and the slider front end 623 is separated from the sold-out actuator 63.

As a result, the sold-out actuator 63 is in a retracted position from the advanced position when the inclined extending portion 633 is pressed by the product W constrained between the frontmost pitches as shown in FIG. As shown in the figure, when the product is not restrained between the pitches in the forefront zone, the player takes the advance stance.

By the way, the products dispensed from the spiral 50 are received by the transport tray 12 and transported by the transport tray 12 to the vicinity of the product outlet 15a. The product is then ready to be taken out through the product take-out port 15a.

As described above, in the product storage device 20 according to the embodiment of the present invention, since the regulating member 71 is attached to the right side portion 611c of the base base portion 611, a flexible triangular columnar shape such as a sandwich is formed. In addition, when the product is restrained between the pitches of the spiral 50 in a posture in which the rectangular surface is the bottom surface and the product is constrained between the pitches of the spiral 50, even if the spiral 50 rotates clockwise when viewed from the front, the right side portion 611c of the base 611 is The upper wall portion 712 that continuously extends upward can prevent the product from moving to the right, and can prevent a part of the product from being sandwiched between the spiral 50 and the base 61. Therefore, it is possible to satisfactorily store and carry out a product which has a flexible triangular columnar shape and which has a rectangular surface as a lower surface and is laid down sideways.

Particularly, since the restricting member 71 is detachably attached to the base 61, the restricting member 71 can be removed to store the product when the product does not have a flexible triangular prism shape. The versatility can be improved.

According to the product storage device 20, the joint member 45 that supports the rear end portion 51 of the spiral 50 constitutes the drive mechanism 41 and is detachable from the transmission member 44 attached to the drive source. By removing 45 from the transmission member 44, the spiral 50 can be replaced while leaving the transmission member 44, and the replacement work of the spiral 50 can be simplified.

Further, the upper support piece 613b of the base 61 is located on the front side of the rear end portion 51a of the spiral 50 when the spiral 50 is in the standby state before rotation, and is seen from the rear end portion 51a and the front side. Even if the spiral 50 is pulled forward, the upper support piece 613b abuts the rear end portion 51a of the spiral 50 to prevent the spiral 50 from being pulled forward and removed. You can That is, when performing the replacement work of the spiral 50, the upper support piece 613b and the rear of the spiral 50 are elastically deformed by pressing the upper support piece 613b downward while separating the joint member 45 from the transmission member 44. The spiral 50 can be removed by releasing the state in which the end portion 51a overlaps with the end portion 51a when viewed from the front. Therefore, it is possible to prevent the unintended detachment of the spiral 50 while simplifying the replacement work of the spiral 50.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

In the above-described embodiment, the sold-out actuator 63 detects the presence or absence of a product by moving the sold-out actuator 63 or retreating from the advanced posture, but in the present invention, the presence or absence of the product is detected by, for example, an optical sensor. You may make it detect using.

In the above-described embodiment, the joint member 45 is detachably attached to the transmission member 44 by, for example, snap fitting, but in the present invention, the coupling between the joint member and the transmission member may be detachable. The form is not particularly limited.
