Description

Label automatic attaching apparatus and label automatic attaching method

The present invention is an automatic label applying apparatus for sequentially peeling labels one by one from a long label strip in which many single labels are shifted little by little and overlapping one another and connecting them. It relates to a method of automatically attaching a label.

2. Description of the Related Art Conventionally, a large number of labels attached to adherends such as goods are attached to a release paper at intervals with intervals, and are wound around a core tube together with the release paper. In the label adhered to the release paper, information such as a trademark and a price is printed on the surface (one side) of the label substrate, and an adhesive is applied to the back surface (the other side) of the label substrate. The adhesive on the back of the label and a material that easily separates from the release paper are used. Generally, labels are peeled off one by one from a release paper by an automatic label affixing device and attached to a product (Patent Document 1).

Here, the label affixing method in the conventional label automatic affixing device will be described based on FIG. A label roll 74 having a release paper 72 to which a large number of labels 70 attached is wound around a core is mounted on a supply shaft 76, and the release paper 72 after peeling off the label 70 is mounted on a take-up shaft 78. The supply shaft 76 and the take-up shaft 78 are rotated at the same rotational speed to move the release paper 72 to which the label 70 is attached. During the movement of the release paper 72, a reversing shaft 80 is provided to reverse the advancing direction of the release paper 72 to an acute angle, and the advancing direction of the release paper 72 is reversed to an acute angle before and after the reversing shaft 80. At the position of the reversing shaft 80, the label 70 is peeled off from the release paper 72, and the label 70 advances in the direction in which it has been moved. Thereafter, the release paper 72 from which the label 70 has been peeled off is wound around a core tube on the side of the winding shaft 78.

On the other hand, an adherend 82 such as a bottle to which a label is attached is placed on a commodity transfer belt conveyor 84 and passes near the reversing shaft 80. The traveling direction of the commodity transfer belt conveyor 84 carrying the adherend 82 and the traveling direction of the release paper 72 with the label 70 attached thereto are set to be the same direction of intersecting at an acute angle. . The label 70 peeled off at the position of the reversing shaft 80 is peeled off from the release paper 72, advances in the direction in which it has traveled, and protrudes to a position where the adherend 82 passes. The adherend 82 moving in the moving direction of the product transfer belt conveyor 84 contacts the adhesive coated surface of the label 70 peeled off from the release paper 72, and the label 70 is adhered to the adherend 82. Although the advancing direction of the product transfer belt conveyor 84 and the advancing direction of the release paper 72 to which the label 70 is attached is at an acute angle, the label 70 (the rear end is the release paper 72 The adhesive is pulled by the adherend 82, and the label 70 can be easily removed from the release paper 72.

In Patent Document 1, the label 70 and the label 70 are attached at intervals to the release paper 72, so after taking out one label 70 from the release paper 72, the length of one label 70 is taken. The release paper 72 has to be moved by the total length of and the gap between the labels. That is, each time the label 70 is peeled off, the release paper 72 must be moved by a long distance. Therefore, in the case of using the release paper 72, if it is intended to attach a large amount of labels 70 per unit time, the release paper 72 must be moved at high speed, and the device is complicated for moving the release paper 72 at high speed In addition, there is a drawback that the size becomes large and the cost increases. Furthermore, it is necessary to wind up the release paper 72 after the label 70 is peeled off, and a space for winding up the release paper 72 is required, resulting in a disadvantage that the entire apparatus has to be large.

If no release paper is used to apply the label, not only the cost reduction can be achieved by not using the release paper, and the generation of carbon dioxide due to incineration of the release paper can be eliminated. For this reason, the label which does not use release paper conventionally is provided (patent document 2). The label which does not use this release paper is obtained by forming perforations in the length position of each single label on a long strip-shaped label main body. Before attaching the label to the product, the perforations are cut from the long strip-shaped label main body to form a single label, and the single label is attached to the adherend.

This patent document 2 has the advantage of not using release paper. However, in order to make a single label from the long strip-shaped label main body of this patent document 2, it is necessary to cut a perforation for every single label, and to make a single label. It took time. For this reason, there existed a fault that a lot of labels could not be stuck per unit time.

In the label of Patent Document 2 which does not use release paper, the outer shape of a single label is limited to a quadrilateral, and there is a disadvantage that the bonding position of the label on the adherend is also limited to the outer shape of this quadrilateral. In order to overcome this drawback, there is provided an invention which does not use a release paper and which can use a label having a free shape such as a circular shape, a triangular shape or an elliptical shape (Patent Document 3). The label of this patent document 3 is shown in FIG.10 and FIG.11. According to FIGS. 10 and 11, a label strip 8 in which many single labels (for example, circular shapes) 1a, 1b, 1c, 1d, 1e, 1f, 1g... The label strip 8 is wound around a tubular core 7 to form a label roll 6. In Patent Document 3, a single label is provided with a printing unit 3 on which information is printed on one side of a label substrate 1 and, for example, a release agent 4 is applied on the upper side of the printing unit 3. The surface is coated with, for example, the adhesive 5 (adhesive means). A

single label

1a, 1b, 1c, 1d, 1e, 1f, 1g is shifted little by little and superimposed (in FIG. 11, a portion where the label 1a is superimposed on the label 1b is referred to as "overlapping portion 1x"), The long label strip 8 is formed by sequentially bonding the overlapping portions 1x of the release agent 4 on one surface side of the pair of adjacent labels and the adhesive 5 on the other surface side. The label of this patent document 3 has the advantages of not using a release paper and being able to use a label of an arbitrary external shape other than a square. However, an apparatus or method for applying a large amount of labels per unit time to an adherend by using the label strip 8 of Patent Document 3 has not been provided yet.

The

single labels

1a, 1b, 1c, 1d, 1e, 1f and 1g (see FIG. 10) can be easily peeled off one by one from the long label strip 8 shown in Patent Document 3 per unit time. The inventors of the present invention have provided an automatic label affixing device and a label affixing method that can automatically attach a large amount of labels to adherends (Patent Document 4). The automatic label affixing device and the label affixing method of Patent Document 4 will be described based on FIG.

.. A label strip 8 (FIG. 10) in which many

single labels

1a, 1b, 1c, 1d... Be The end of the label transfer belt conveyor 50 in the direction of movement is provided with a reverse shaft 52 for reversing the belt conveyor, and at the position of the reverse shaft 52, the label transfer belt conveyor 50 has its direction of movement close to 180 degrees. It is set to reverse at an angle. When the label strip 8 is moved together with the belt conveyor 50, the leading end 1y of the leading label 1a of the label strip 8 is peeled off from the label transfer belt conveyor 50 at the position where the label transfer belt conveyor 50 is reversed. It projects away from the label transfer belt conveyor 50 by the length of the part 1y (FIG. 12 (a)). The label holding member 54 is provided near the position of the reversing shaft 52 for reversing the label transfer belt conveyor 50, and the label holding member 54 and the reversing shaft 52 transfer the label 1a at a head (a place other than the tip 1y) The belt conveyor 50 is pinched.

The goods transfer belt conveyor 56 is disposed at a lower position near the reversing shaft 52 which reverses the label transfer belt conveyor 50 (FIG. 12). An adherend 58, which is a product for attaching a label, is placed on the product transfer belt conveyor 56, and is transferred by the product transfer belt conveyor 56 in a predetermined direction. An air jet means 60 is provided near the reverse shaft 52 of the label transfer belt conveyor 50, and air is jetted from the air jet means 60 to the surface of the leading end 1y of the leading label 1a to which the adhesive 5 is applied. Ru.

The first sensor 62 on the relatively upstream side and the second sensor 64 on the downstream side relative to the upstream side and the second sensor 64 sequentially in the direction of movement of the commodity transfer belt conveyor 56 on both sides or one side in the vicinity of the commodity transfer belt conveyor 56. Is provided. When the first sensor 62 detects the adherend 58, the first sensor 62 operates the air jetting means 60 to jet air to the adhesive 5 side of the tip portion 1 y of the label 1 a at the leading position of the label strip 8. The air from the air jetting means 60 jetted to the adhesive 5 side of the leading end 1y of the leading label 1a warps the surface on the adhesive 5 side of the leading end 1y of the label 1a in an arc curve shape outward. Make it With the adhesive 5 side of the tip 1y of the label 1a warped outward, the product transfer belt conveyor 56 moves, and the adherend 58 contacts the adhesive 5 side of the tip 1y of the label 1a ( Figure 12 (b). The injection of the air from the air ejection means 60 is stopped shortly before the product transfer belt conveyor 56 reaches the position shown in FIG. 12 (b).

When the ejection of air from the air ejection means 60 is stopped, the tip 1y of the label 1a which is warped in an arc shape tries to return linearly, but adhesion of the tip 1y of the label 1a kept in a warped state. The adherend 58 comes into contact with the agent 5, and the tip end 1y of the label 1a is adhered to the adherend 58. Since the adherend 58 moves in a state where the leading end portion 1y of the label 1a is adhered, the overlapping portion 1x of the first label 1a starts to peel off from the label 1b, and from the state of FIG. Change to the state. Thereafter, by moving the adherend 58 placed on the commodity transfer belt conveyor 56, the label 1a is peeled off from the label 1b and completely adhered to the adherend 58.

As described above, in Patent Document 4, the adherend 58 moved by the commodity transfer belt conveyor 56 by causing the leading end portion 1y of the leading label 1a in the label strip 8 to leave the label transfer belt conveyor 50 and project outside. The label 1a is adhered to the After the label 1a adheres to the first adherend 58, the label transfer belt conveyor 50 moves so that the next label 1b is at the top, and the tip 1y of the label 1b is the next adherend 58 and It projects away from the label transfer belt conveyor 50 so as to be adhesively bonded. The next adherend 58 comes in contact with the leading end 1y of the label 1b to adhere the label 1b to the adherend 58. Thereafter, the labels are peeled off one by one from the label strip 8 and the labels are sequentially affixed to the adherend 58.

In the case where the label is attached on the release paper of the conventional patent document 1, the distance for moving the release paper when attaching one label is a length obtained by combining the length of one label and the gap between the labels. Distance. On the other hand, in Patent Document 4, the distance for moving the label strip 8 at the time of attaching one label is only the length (generally, about 2 to 10 mm) of the tip portion 1y of the leading label 1a. In this patent document 4, the label 1a at the top of the label strip 8 can be easily peeled off from the label strip 8, and the moving distance of the label strip 8 for each label is from one label It is the length obtained by subtracting the overlapping portion with another label, and the moving distance of the label strip 8 can be shortened. Therefore, the number of adhered labels to the adherend 58 per unit time is compared with the conventional one. It can be dramatically increased and the economic efficiency can be improved.

The automatic label affixing apparatus according to the present invention has, in addition to the first belt 10, a loop-shaped second belt 22 for temporarily bonding and moving the labels peeled off from the label strip 8 one by one. The second belt 22 is wound around the second driving roller 26, the second reverse shaft 28 and other rollers rotated by the second driving means 24, and the rotation of the second driving roller 26 causes the direction of the arrow (see It is moved to During operation of the apparatus, the drive roller 26 rotates at a constant speed, and the second belt 22 moves continuously in a loop at a constant speed. The second belt 22 is set to move in contact with a part of the outer periphery of the large diameter portion 16 a of the composite shaft 16.

When the movement of the first belt 10 is stopped (standby state), as shown in FIG. 2, the leading end 1y of the leading label 1a of the label strip 8 is in a state of being peeled off from the first belt 10 The leading end position of the leading end portion 1y of the label 1a is set so as to be in contact with the second belt 22 a little more. When the first belt 10 starts moving from the state of FIG. 2, the leading label 1 a is moved in the same direction as the moving direction before the first belt 10 is reversed by the compound shaft 16. That is, as shown in FIG. 3A, the surface on the adhesive (adhesion means) 5 side of the leading end position of the tip portion 1y of the label 1a is adhered (temporarily adhered) to the second belt 22. Assuming that the angle between the tip portion 1y of the label 1a and the second belt 22 in contact is θ1, if the θ1 is around 90 degrees or an acute angle, the tip portion 1y of the label 1a moves to the second belt 22 Then, as shown in FIG. 3A and FIG. 4, the entire surface of the label 1 a on the side of the adhesive 5 adheres to the second belt 22.

When the first label 1a is peeled off from the label strip 8 and the leading end position of the leading end 1y of the second label 1b comes to a position where it contacts the second belt 22 a little more, the first belt 10 stops moving. The state at the time of the stop is the state shown in FIG. 2 (the state before the leading edge of the next label 1 b contacts the second belt 22). Thereafter, when the first belt 10 starts moving again, the next label 1 b adheres to the second belt 22 as shown in FIG. 2 and FIG. 3. As a result, as shown in FIG. 5, the labels 1 are temporarily adhered to the second belt 22 one by one at a time with a slight interval.

The label 1a adhered to the second belt 22 is then conveyed to a second reversing shaft 28 (FIG. 1) for reversing the second belt 22 by approximately 180 degrees. The label 1 temporarily bonded to the second belt 22 is for preventing falling off from the second belt 22 or to reinforce the temporary bonding on the way to move the second belt 22 to the second reverse shaft 28. The second belt 22 is pressed by the pressing means 30 of the second embodiment. The pressing means 30 is preferably provided, but may not be provided. Further, a heating means for heating the label 1 temporarily bonded to the second belt 22 may be provided in the vicinity of the second reversing shaft 28 inside or outside the loop-shaped second belt 22.

The label 1 which has reached the position of the second reversing shaft 28 is peeled off from the second belt 22 by reversing the second belt 22 at the second reversing shaft 28, and the second belt just before reaching the second reversing shaft 28 position It is peeled off from the second belt 22 in the same direction as the moving direction of 22 and is projected to the outside. A pressing roller (pressing means) 32 for pressing the label 1 against an adherend 36 (described later) is provided in the vicinity of the protruding position of the label 1 to be peeled off from the second belt 22. The label 1 separated from the belt 22 is brought into contact with the adherend 36.

As shown in FIG. 1 (plan view), a goods transfer belt conveyor 34 is provided below the arrangement position of the second reversing shaft 28. An adherend 36, which is a product for attaching a label, is placed on the commodity transfer belt conveyor 34, and the adherend 36 is placed on the commodity transfer belt conveyor 34 and transported in a predetermined direction. . The moving speed of the product transfer belt conveyor 34 and the moving speed of the second belt 22 are basically set to the same speed. Further, the traveling direction of the commodity transfer belt conveyor 34 and the traveling direction of the second belt 22 immediately before reaching the position of the second reverse shaft 28 are the same traveling direction (not opposite direction). The angle θ2 between the direction of travel of the product transfer belt conveyor 34 and the direction of travel of the second belt 22 can be a small acute angle (eg, θ2 of 15 ° to 45 °). As a result, the label 1 is advanced in the advancing direction substantially in line with the advancing direction of the adherend 36, and the moving speeds of the labels 1 are the same speed, so that the surface of the adherend 36 is slippery, The label 1 can be reliably attached to a predetermined position of the adherend 36.

Sensors 38 are provided on both sides or one side in the vicinity of the product transfer belt conveyor 34. When the sensor 38 detects the arrival of the adherend 36 at a predetermined position, the sensor 38 operates the first drive means 12 to move the first belt 10, and the label 1a at the head position of the label strip 8 is moved to the second position. The belt 22 is brought into contact. The timing at which the label 1 a contacts the second belt 22 matches the timing at which the label 1 peeled off from the second belt 22 adheres to the adherend 36. The timing for starting driving the first driving means 12 and the timing for stopping driving may be performed by means other than the sensor 38. The first drive means 12 is set to stop the operation when a predetermined time has elapsed after the operation. Alternatively, another sensor other than the sensor 38 may be provided in the vicinity of the commodity transfer belt conveyor 34 so as to stop the operation of the driving means 12 when another sensor detects the adherend 36.

Next, an operation of attaching the label 1a to the adherend 36 by using the present invention will be described. The label strip 8 pulled out from the label roll 6 shown in FIG. 1 is held between the first drive roller 14 and the nip roller 18 in the middle thereof, and the adhesion direction side is temporarily adhered to the first belt 10 from the holding position. It is done. As shown in FIG. 2, in the state where the movement of the first belt 10 and the label strip 8 is stopped (standby state), the leading end of the tip portion 1 y of the leading label 1 a of the label strip 8 is the second The position is set so as to be slightly in front of the belt 22. Even in the standby state in which the movement of the first belt 10 and the label strip 8 is stopped, the goods transfer belt conveyor 34 which moves with the second belt 22 and the adherend 36 moved continuously. Do.

In the standby state, when the sensor 38 detects the adherend 36 which is placed on the commodity transfer belt conveyor 34 and moves at a predetermined position, the first drive means 12 operates to operate the first belt 10 and the label strip 8. Move By driving the first drive means 12, the leading end portion 1 y of the leading label 1 a of the label strip 8 is adhered to the second belt 22. When the leading end portion 1y of the next label 1b arrives slightly before the second belt 22, the operation of the first driving means 12 is stopped. In the state where the operation of the first drive means 12 is stopped, the label strip 8 is in the same standby state as in FIG. That is, when the first driving means 12 is driven once, the next label 1b is located at the position where the label 1a shown in FIG. 2 was present, and the next label 1c is located at the position where the label 1b was present. .

Even if the drive of the first drive means 12 is stopped, the second belt 22 is moved, and therefore, the entire length of the label 1a is peeled off from the label strip 8 by being pulled by the second belt 22 and the second belt 22 Bond to While the label 1a is sequentially adhered to the second belt 22 in its entire length, the label 1 (located near the second reverse shaft 28) peeled off from the second belt 22 is attached to the adherend 36 Make sure that the entire length adheres sequentially.

When the sensor 38 detects the next adherend 36 placed on the commodity transfer belt conveyor 34, the first drive means 12 operates to move the first belt 10 and the label strip 8. As a result, the label at the leading end (the leading end in FIG. 2) of the label strip 8 is adhered to the second belt 22, pulled by the second belt 22, and adhered to the second belt 22. At the same time, the label 1 already adhered to the second belt 22 and located near the second reverse shaft 28 is peeled off from the second belt 22 and adhered to the adherend 36. Hereinafter, the same operation is repeated.

In the present invention, the first belt 10 and the label strip 8 are intermittently moved to bond the labels 1 from the label strip 8 one by one to the second belt 22 at intervals. The label 1 adhered to the second belt 22 with a gap therebetween is peeled off from the second belt 22 at the position of the second reversing shaft 28. The label 1 peeled off from the second belt 22 is moved along the traveling direction on the upstream side of the second reversing shaft 28, and is placed on the commodity transfer belt conveyor 34 and moved. It adheres to 36 in order.

As described above, in the present invention, the advancing direction of the label 1 peeled off from the second belt 22 is the same as the advancing direction of the adherend 36 (not the reverse direction), and the label 1 and the adherend 36 Is moved at the same speed. The angle θ2 between the direction of travel of the label 1 and the adherend 36 can be set to a small acute angle (eg, 15 ° to 45 °). As a result, the advancing direction of the label 1 peeled off from the second belt 22 and the advancing direction of the adherend 36 become nearly parallel, and it becomes easy to bond the label 1 to the surface of the adherend 36. Therefore, even if the material of the adherend 36 is slippery when the label 1 is adhered, the label 1 can be adhered to the adherend 36 reliably and in a predetermined position without slipping.

In FIG. 2 to FIG. 4, the label 1a on the tip side of the moving label strip 8 collides with the moving second belt 22 and the adhesive 5 side of the tip of the label 1a adheres to the second belt 22. Since the second belt 22 is always moving, the label 1a adhered to the second belt 22 moves while being pulled by the second belt 22, and the adhesive 5 side of the label 1a is brought into contact with the second belt 22. When the angle at which the label 1 a on the tip side of the label strip 8 collides with the second belt 22 is close to a right angle, the adhesive 5 near the tip of the label 1 a may not contact the second belt 22 . Therefore, in order to bring the adhesive 5 side of the label 1a on the front end side of the label strip 8 into contact with the second belt 22, the adhesive 5 side of the vicinity of the front end of the label 1a is surely faced to the second belt 22 An embodiment which is made to do this is shown in FIG.

In FIG. 6, the air jetting means 40 is provided near the compound shaft 16. The air ejected from the air ejection means 40 is for ejecting the air to the position of the adhesive 5 at the tip portion 1y of the leading label 1a in the standby state. In the standby state, the leading end 1y of the leading label 1a is not adhered to the next label 1b or the like. In the standby state, the air jetting means 40 is provided at a position facing the surface provided with the adhesive 5 (adhesion means) of the front end portion 1y of the leading label 1a of the label strip 8. When moving the label strip 8 together with the first belt 10 from this standby state, the air jetting means 40 is operated to jet air toward the adhesive 5 side of the tip portion 1y of the label 1a. The surface of the leading end 1y of the leading label 1a on the adhesive 5 side is curved in an arc toward the outside (opposite to the adhesive 5) by the jetted air. The adhesive 5 side of the leading end 1y of the leading label 1a is made to face the second belt 22 by curving the surface of the leading end 1y of the leading label 1a on the adhesive 5 side toward the opposite side of the adhesive 5. By the movement of the label strip 8 and the movement of the second belt 22, the adhesive 5 side of the tip portion 1y of the label 1a can be reliably brought into contact with the second belt 22. When the adhesive 5 side of the leading end portion 1y of the label 1a adheres to the second belt 22, the ejection of air is stopped. Thus, the label 1 can be reliably adhered to the second belt 22 by using the air ejection means 40.

Next, FIG. 7 and FIG. 8 temporarily bond the label 1 (label 1a) to the second belt 22 and show a structure and method different from those of FIG. In FIG. 6, the adhesive 5 side of the front end portion 1y of the leading label 1a to be peeled off from the label strip 8 is bent back by the air injection means 40 so as to face the second belt 22, the adhesion of the label 1a The agent 5 side is adhered to the second belt 22. When this air injection means 40 is used, the adhesive 5 side of the leading end portion 1y of the label 1a is located at an intermediate position of the second belt 22 (intermediate position between the left and right end rollers) stretched between the left and right end rollers. Contact For this reason, the interval between the rollers at the left and right ends of the second belt 22 is long, and the length of the second belt 22 is long.

FIGS. 7 and 8 show another structure and method for temporarily bonding the adhesive 5 side of the leading end portion 1y of the leading label 1a to the second belt 22, and the air jet means 40 shown in FIG. Instead, a three-dimensional label moving member 90 is used. The label moving member 90 changes the moving direction (direction E in FIG. 7) of the leading end portion 1y of the leading label 1a peeled off from the label strip 8 and reverses the label 1a, and the label 1a is moved to a predetermined position of the second belt 22. It is for moving toward (described later). The label moving member 90 has a protrusion 92 for pressing the adhesive 5 side of the tip portion 1y of the label 1a to invert the tip portion 1y of the label 1a.

In FIG. 7, the label moving member 90 moves its center-of-gravity position in the order of the position A, the position B, the position C, and the position D. One moving end of the label moving member 90 is set to a position A, the other moving end is set to a position D, and the middle position of movement is set to a position B or a position C. When the label moving member 90 reaches the position D, it returns to the position A via the position C and the position B. The position A of the label moving member 90 is in a standby state in which the movement between the first belt 10 and the label strip 8 is stopped. In this standby state, the tip of the tip portion 1y of the label 1a is a label moving member 90 It is arranged in a close position but not in contact with the label moving member 90. Thereafter, the standby state is released, and the leading end 1y of the label 1a advances in the direction E in FIG. 7, and a part of the leading end 1y of the label 1a passes near the protrusion 92 of the label moving member 90. The label moving member 90 moves in a direction substantially perpendicular to the moving direction (direction E) of the tip portion 1y of the label 1a, and the protrusion 92 of the label moving member 90 presses the adhesive 5 side of the tip portion 1y of the bell 1a. .

The protruding portion 92 of the label moving member 90 pushes the adhesive 5 side of the tip portion 1y of the bell 1a, so that the adhesive 5 side of the tip portion 1y of the label 1a is exposed to the outside of the arc shape Are inverted (the state of position B of the label moving member 90). Thereafter, the label moving member 90 moves the label 1a along the direction in which the tip end 1y of the label 1a is inverted. The label moving member 90 moves the label 1a which has been kept inverted. That is, the label moving member 90 continues to move in the direction moved in a direction substantially perpendicular to the moving direction (direction E) of the tip portion 1y of the label 1a at the position A, from the position B to the position C in FIG. Move.

While the label moving member 90 is moved from the position B to the position C, the advancing direction of the tip portion 1 of the label 1 a is completely reversed, and the label 1 is attached to one surface (joining surface) 94 of the label moving member 90. Contact with the adhesive 5 side of the Thereafter, while the label moving member 90 is moved from the position C to the position D, the bonding surface 94 of the label moving member 90 and the adhesive 5 side of the label 1a are in contact with each other. 90 and label 1a move in a linear direction.

When the label moving member 90 has reached the position D, as shown in FIG. 8, the adhesive 5 side of the leading end of the label 1a contacts the second belt 22 and presses the roller 96 on which the second belt 22 is wound It is nipped between the roller 98. The label 1 is pressed and held (moved) by the roller 96 and the pressing roller 98, the label 1 is in a state of being temporarily adhered to the second belt 22, and the label 1 is moved together with the second belt 22.

When the label 1 is temporarily adhered to the second belt 22 and moved together with the second belt 22, the label moving member 90 returns from the position D to the position A via the positions C and B. After that, when the next label 1 moves again and its leading end passes near the protrusion 92 of the label moving member 90, the label moving member 90 moves to press the label 1 and reverse the moving direction of the label 1 , And moved together with the label moving member 90. The label 1 is finally sandwiched between the roller 96 and the pressure roller 98, temporarily adhered to the second belt 22, and moved together with the second belt 22. Such an operation is sequentially repeated to temporarily bond the labels 1 one by one to the second belt 22. When the label moving member 90 is used, the label 1 can be temporarily adhered to the second belt 22 at the roller 98 position which is the reverse position of the second belt 22. Therefore, when the label moving member 90 is used, the length of the second belt 22 can be shortened.
