Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The label sticking apparatus of the present invention particularly relates to a label sticking apparatus for completely sticking a label piece to the bottom surface of an object to be stuck at the raised bottom.

[0002]

[Prior art]

 Conventionally, as a label sticking device for sticking a label piece temporarily attached to a strip-shaped continuous mount (hereinafter simply referred to as a mount) to an adherend such as a packaging box or a product conveyed by a conveyor, for example, There is one as shown in FIG.

In this label sticking apparatus, a strip-shaped continuous body 10 in which a plurality of label pieces are temporarily attached to a mount is unwound from a label supply shaft 8 attached to a body side plate 6 and wound to a thermal head 12. Information is printed on the label piece 20 by the thermal head 12 when it is sandwiched between the platen 14 and the platen 14. Then, the printed label pieces 20 are peeled from the mount one by one by the label peeling plate 15, and the label pieces are attached to the spring belt 28 hung between the main shaft 24 and the sub shaft 26 of the label guide means 23. The surface 20a having the adhesive layer 20 is lightly adhered and is sent upward by the rotation of the spring belt 28, and reaches the vicinity of the sub shaft 26.

After the label pieces 20 are peeled off by the label peeling plate 15, the mount is turned around and is wound around the mount winding shaft 18 via the feed roller 16.

A first conveyor 44 and a second conveyor 48 are arranged on both sides of the label guide means 23, and the upper surfaces of the belts 43 and 47 which are hung on the first conveyor 44 and the second conveyor 48 are arranged in a substantially horizontal state. The adherend 50 such as a cardboard box or product placed on the first conveyor 44 and conveyed is a bottom surface of the adherend 50 on the way to the side of the second conveyor 48. The label piece 20 temporarily attached to the spring belt 28 of the label guide means 23 is attached to a predetermined position of the portion 50a in the vicinity of the sub shaft 26.

As described above, until the label continuous body 10 is unwound from the label supply shaft 8 and the label piece 20 is attached to the bottom surface portion 50 a of the adherend 50 via the label guide means 23. Label supply device ".

[0007]

[Problems to be solved by the device]

 However, when the label piece 20 is stuck to the pasting object 50 conveyed from the first conveyor 44 to the second conveyor 48, the bottom surface portion 50 a as the “sticking surface” of the label piece 20 has the belt 43. , 47 is easy to attach when it is in a low position, but the attachment surface is in a high position without contacting the belts 43, 47. In the case of the object 50, the sticking of the label piece 20 was sometimes incomplete. That is, when the bottom surface portion 50a of the adherend 50 is at a low position, the label piece 20 sent to the vicinity of the sub shaft 26 of the spring belt 28 may be close to the bottom surface portion 50a because the distance to the bottom surface portion 50a is short. Although it is easy to attach the label piece 20, if the bottom portion 50b of the raised bottom is used, the distance between the counter shaft 26 and the bottom portion 50b of the raised bottom may become long, so that one end of the label piece 20 is temporarily attached to the bottom portion 50b. So to speak, there was a risk of being conveyed to the next stage in an incomplete state.

Therefore, there has been a demand for the development of a label sticking device capable of completely sticking a label piece even if the adherend 50 has a raised bottom.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the present invention provides a second conveyor with a space between the first conveyor and the first conveyor, and the second conveyor is arranged below the first and second conveyors. The strip-shaped continuous body is wound out from the label supply device around which the strip-shaped continuous body is wound, the label pieces are separated from the strip-shaped continuous body, and the adherend is placed on the first conveyor and conveyed. A label sticking device for sticking the separated label pieces, wherein a rotatable pressure roller is provided between the label supply device and a second conveyor, and the upper end of the pressure roller is the label piece. It is characterized in that it is provided higher than the belt surface of the first conveyor on which the object to be adhered is placed so that the bottom surface part of the raised bottom of the object to be adhered is pressure-contacted thereto via.

Further, a rotatable pressure roller is disposed on the downstream side of the second conveyor and in the vicinity of the conveyor, and the upper end of the pressure roller is provided with the label piece through the label piece. It is characterized in that it is provided higher than the belt surface of the second conveyor on which the object to be adhered is placed so that the bottom surface of the raised bottom is brought into pressure contact.

[0011]

[Action]

 While the adherend is being conveyed from the first conveyor to the second conveyor, a label piece is temporarily attached to the bottom surface of the raised bottom from the label supply device. Then, in the case of claim 1, when the adherend is conveyed, the pressure roller is rotatable between the label supply device and the second conveyor, and the upper end of the pressure roller is higher than the first belt surface. Since the pressure roller presses the bottom surface of the adherend through the label piece, the label piece temporarily attached to the bottom portion can be completely attached to the bottom portion. become. Moreover, since the pressure-applying roller acts immediately after the label piece is temporarily attached to the bottom surface of the adherend by the label supply device, the incompletely attached state of the label piece is immediately eliminated.

Further, in the case of claim 2, since the pressure bonding roller is provided not on the first and second conveyors but on the downstream side of the second conveyor and close to the conveyor, the first and second conveyors are provided. The space between the two conveyors can be small, and thus the label sticking device itself can be small.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. Note that the description of the parts described in the related art will be omitted because they overlap. Reference numeral 70 denotes a label crimping portion, and the label crimping portion 70 is mainly composed of an elastic compression spring 71, a shaft 72, a spring receiver 73, and a gear 74 as a “crimping roller”.

At one end of the compression spring 71, one ends of shafts 72a and 72b fitted with spring receivers 73a and 73b are inserted. Then, the other ends of the shafts 72a and 72b are inserted into the main body side plate 6 between the label guide means 23 of the "label supply device" and the second conveyor 48, whereby the compression spring 71 is caused to move to the shaft 72a, It is supported by being sandwiched by 72b.

The other end of the shaft 72b is fixed to a gear 74 connected to a drive source (not shown), and rotation of the gear 74 transmits the rotation via the shaft 72b to the compression spring 71. The compression spring 71 rotates.

The rotation of the gear 74 is a rotation in the carrying direction (clockwise in FIG. 1), and the compression spring 71 rotates in the carrying direction in accordance with the rotation of the gear 74. Therefore, even if a space for providing the compression spring 71 is required between the label guide means 23 and the second conveyor 48, the compression spring 71 also functions as a "passing roller". Therefore, the adherend 50 is conveyed to the second conveyor 48 side without stopping there.

As described above, since the compression spring 71 and the shafts 72a and 72b can be disassembled and assembled freely, the depth of the raised bottom, that is, the first and second conveyors, varies depending on the type of the target adherend 50. It is easy to replace the compression spring 71 with a different diameter so that the surface of the compression spring 71 is pressed against the bottom surface 50b of the raised bottom according to the distance from the upper surface of the belt 43, 47 of the belt 44, 48 to the bottom surface 50b. Is.

The compression spring 71 is provided at a position higher than the upper surface of the belt 43 of the first conveyor 44. Further, since the compression spring 71 is used as the "compression roller", if the compression spring 71 having a diameter slightly larger than the diameter of the lightly contacting the bottom surface portion 50b is adopted, the pressure bonding force to the bottom surface portion 50b can be increased. become.

Reference numeral 40 denotes an intermediate roller, which is located between the first conveyor 44 and the second conveyor 48, which require a certain distance due to the presence of the label guide means 23 and the compression spring 71. It is provided so that a particularly small cardboard box or an object to be adhered 50 such as a product, which is placed on the first conveyor 44 and conveyed, can be temporarily ridden and smoothly conveyed to the second conveyor 48 side. .

Next, the operation will be described. While the adherend 50 is being conveyed from the first conveyor 44 to the second conveyor 48, the label piece 20 is temporarily attached from the label guide means 23 of the “label supply device” to the bottom portion 50b of the raised bottom. And is conveyed to the second conveyor 48 side, a compression spring 71 is provided between the label drafting means 23 and the second conveyor.

The compression spring 71 is provided higher than the upper surface of the belt 43, and rotates by being pressed against the bottom surface portion 50b of the raised bottom that has been conveyed, and the label piece 20 temporarily attached to the bottom surface portion 50b is Since the compression piece 71 is crimped and conveyed, the label piece 20 is completely attached to the bottom surface portion 50b. Since the compression spring 71 is provided so as to rotate in the conveying direction, it also acts as a "passing roller", and the adherend 50 does not stop there but moves toward the second conveyor 48 side in the next stage. Be transported.

As described above, the compression spring 71 is provided between the label guide means 23 and the second conveyor 48, and the label guide means 23 moves the label piece 20 to the bottom surface portion 50 b of the adherend 50. Immediately after being temporarily attached to the label piece 20, the label piece 20 is pressed against the bottom surface portion 50b, so that the label piece 20 is in an incompletely attached state, that is, only one end is temporarily attached to the bottom surface portion 50b. The unstable state of being worn is immediately resolved.

FIG. 4 is a diagram showing a second embodiment of the present invention. According to this embodiment, an elastic sponge 80 is used as the "pressing roller".

The sponge 80 has a through hole 82 communicating with the shaft 81, and is integrally attached to the shaft 81 through the through hole 82.

The shaft 81 is attachable / detachable to / from the body side plate 6, and the sponge 80 is rotatable by locking one end of the shaft 81 to the gear 74. According to the depth of the raised bottom that differs depending on the type of the target adherend 50, that is, the distance from the top surface of the belts 43 and 47 to the bottom surface portion 50b, sponges 80 having a plurality of types of diameters are prepared. Is integrally attached to the shaft 81 in advance. At the time of sticking, a shaft 81 having a diameter corresponding to the depth of the raised bottom of the object to be stuck 50 is attached.

By using the sponge 80 as the pressure roller, the belt 43 can be attached even if the object 50 to be adhered is light in weight or if the depth of the bottom surface portion 50b varies to some extent. If a pressure roller having a diameter slightly larger than the distance from the upper surface of the bottom surface 50b to the bottom surface 50b is used, the adherend 50 does not float up due to the bending of the sponge 80, and the label piece 20 temporarily attached to the bottom surface 50b. Can be pressure-bonded to the bottom surface portion 50b. The other operations are the same as those in the previous embodiment, and the description thereof will be omitted.

FIG. 5 is a diagram showing a third embodiment of the present invention. In this embodiment, the pressure bonding roller 85 is provided on the downstream side of the second conveyor 48 and in the vicinity of this conveyor 48.

The pressure roller 85 is integrally attached to the shaft 86, and is also exchangeably attached to a substrate (not shown) separate from the main body side plate 8. That is, the label guide means 23 between the first and second conveyors 44 and 48 temporarily attaches the label piece 20 to the bottom surface portion 50b of the raised bottom of the adherend 50, and the label piece 20 is in an incompletely attached state. As it is, it is conveyed to the second conveyor 48, placed on the conveyor 48, and conveyed toward the conveying means (not shown) in the next stage. However, the pressure roller 85 is provided downstream of the second conveyor 48 and in the vicinity of the conveyor 48, and further provided at a position higher than the surface of the belt 47 of the second conveyor 48. The pressure roller 85 is provided so as to rotate in pressure contact with the bottom surface portion 50b of the adherend 50 placed on the conveyor 48 and conveyed. Therefore, the label piece 20 temporarily attached to the bottom surface portion 50b is pressed by the pressure roller 85, so that the label piece 20 is completely attached to the bottom surface portion 50b.

As described above, since the pressure roller 85 is provided on the downstream side of the second conveyor 48, not between the first and second conveyors 44 and 48, the first and second conveyors are The space between the bears 44 and 48 can be small, and thus the label sticking device itself can be small. The other operations are the same as those in the previous embodiment, and the description thereof will be omitted.

It should be noted that although the example in which the compression spring 71 and the sponge 80 are used as the elastic body has been described, it goes without saying that the invention is not limited to this.

[Effect of device]

 According to the present invention, as described above, the pressure roller is provided between the label supply device and the second conveyor so as to be rotatable, and the upper end of the pressure roller is provided higher than the belt surface of the first conveyor. Since the label is rotated and pressed against the bottom surface of the raised bottom of the adherend, the pressure supply roller acts immediately after the label piece is temporarily attached to the bottom surface of the adherend by the label supply device. This has the effect of immediately eliminating the condition of incomplete temporary fitting of one piece. Further, since the pressure roller is rotatably provided, there is an effect that the adherend is not stopped even when the label piece is pressure-bonded to the bottom surface and is conveyed to the second conveyor.

Further, since the pressure bonding roller is provided on the downstream side of the second conveyor, not between the first and second conveyors, the space between the first and second conveyors can be narrowed, so that the label can be attached. The effect is that the device itself can be small.
