Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label transport drum having a glue cleaning mechanism used when transporting a label that has undergone pasting to the next process.

A label that has already been glued, such as a peel-off label △ that is adhered to a tape-like mount (hereinafter referred to as "tag label")
When transferring, as shown in Fig. 3, the label A peeled off from the mount B is sent to the transfer drum C, and this label A is transferred to the next process by passing over the floor surface formed at the bottom of the transfer drum C. do.

However, with gluing, a small amount of glue adheres to the floor surface that the processed label △ comes into contact with and passes through.

Recently, in order to correct the inclination of the label A, such as front rise and rear rise, many apparatuses are equipped with a label presser that presses down the upper edge of the label A to an accurate position while the label A is being transported.

Therefore, glue tends to stick especially when passing through this label holder (glue accumulates more and more).

As a result, the label attempting to pass over the floor surface adheres to the accumulated glue, ensuring smooth passage of the label.

When the labels adhere to each other, nine consecutive labels become clogged one after another, resulting in a large amount of labels being wasted, and there is a problem in that the operation of the apparatus has to be interrupted until the floor has been cleaned.

The present invention was made in order to solve such problems, and it provides a label with a glue cleaning mechanism that removes the glue that adheres to the floor surface during label transport to enable smooth label transport. The purpose is to provide a transfer drum.

Next, an embodiment of the present invention will be described, but first, each part of the device will be described.

[B] Label Peeling Section As shown in FIG. 1, the label 1 is a tag label whose adhesive surface has already been coated with adhesive and can be easily peeled off from the tape-shaped mount 11.

This label 1 is wound up into a roll and mounted on a rotary table 2.

The free end of this tape-like label is pulled out by two pull-out rollers 3.
The tape is drawn out from the turntable 2 by the rotation of the drawing roller 3. Turntable 2
A reversing guide 4 having an acute angle surface is disposed between the pull-out roller 3 and the reversing guide 4.

The reversing guide 4 is installed at a position where the tape-shaped mount 11 contacts the acute-angled surface of the reversing guide 4 and is reversed at an acute angle.

[B] Label transfer section The transfer drum 5 is placed close to the reversing guide 4.

The transfer drum 5 is a drum for attaching a label to a container 6 or the like that approaches the label 1 from the tangential direction of the transfer drum 5.

The transfer drum 5 is a rotating cylinder that rotates around @51 as shown in FIG.

The circumferential surface of the transfer drum 5 has protruding claws 52 divided into equal parts, and a large number of suction holes 53 are formed on the circumferential surface for suction.

Negative pressure may be generated in all the suction holes 53, but a negative pressure groove 54 is formed at the bottom of the transfer drum 5 that connects the reversing guide 4 to the star, and the passage passes above the negative pressure groove 54. The configuration is such that negative pressure is generated only in the suction hole 53 that is exposed to the air.

On the other hand, on the outer periphery of the transfer drum 5, a curved guide plate 7 extending in the rotation direction is arranged parallel to the circumferential surface of the transfer drum 5.

[C] Floor plate Further, the floor plate below the transfer drum 5 is not fixed, but is constituted by a donut-shaped rotating disk 8.

The rotating disk 8 has a maximum diameter larger than the diameter of the transfer drum 5, is made to protrude from the circumferential surface of the transfer drum 5, and the protruding portion is used for sliding labels.

The rotating disk 8 is configured to rotate at a low speed in the same direction as the transfer drum 5 or in the opposite direction (in the case of FIG. 1, in the opposite direction of the transfer drum).

To give rotation to the rotating disk 8, for example, a driving roller may be placed in contact with the periphery of the rotating disk 80 (not shown).
The rotating disk 8 is configured to be rotated by the rotational force of the drive roller.

In short, it is sufficient that the label 1 itself can be moved while supporting the lower edge of the label 1 on the plate surface of the rotating disk 8.

[Box Cleaning Mechanism] Since the glued label 1 passes in contact with the contact surface of the rotating disk 8 that supports the lower edge of the label 1, glue tends to adhere thereto.

Therefore, a cleaning device 81 is installed and placed at a position immediately before receiving the label 1 on the rotating disk 8.

The cleaning device 81 may use, for example, a mechanical method such as scraping the contact surface of the rotating disk 8 with a brush or a sharp grinding blade, wiping it with a sponge wax, a chemical method using chemicals, or heat. It is possible to adopt a known method such as an electrical method.

Next, a method for cleaning glue will be explained.

[The supply container 6 of the container is connected to the belt conveyor from the tangential direction of the transfer drum 5,
It reaches the star 9 from a screw conveyor or the like, is held in the recess 91 of the star 9, and approaches the transfer drum 5.

[Opening] By driving the label supply and draw-out rollers 3, the backing paper 11 between the draw-out rollers 3 starts to move.

The label 1 on the mount 11 approaches the reversing kite 4 as the mount 11 moves, and while the mount 11 moves following the acute angle surface of the reversing guide 4, the label 1 cannot follow the deformation of the mount It is peeled off sequentially starting from No. 11. The peeled bell 1 continues to move while sliding on the floorboard with its lower edge supported by the rotating disk 8.

When the label 1 is pushed out and approaches the circumferential surface of the transfer drum 5, the leading end of the label 1 is attracted by the packing pressure and moves together with the transfer drum 5.

At this time, since the rotating disk 8 is rotating at a low speed, the label 1 smoothly runs on the contact surface of the rotating disk 8 without being adversely affected by the movement of the label 1 being inhibited.

A claw 52 protruding from the peripheral surface of the transfer drum 5 catches up with the tail end of the label, and the label supply timing is corrected.

Simultaneously with the supply timing of the label 1, the inclination of the label 1 is corrected by the plate surface of the rotating disk 8 and the label presser, and the label 1 approaches the star 9.

[C] The pasting angle is corrected to an accurate position, and the label 1 supplied at the proper timing is pasted in contact with the container 6 approaching from the tangential direction of the transport drum 5.

E2] Glue Removal When the label 1 passes over the contact surface of the rotating disk 8, a small amount of glue adheres to the plate surface.

Since the rotating disk 8 rotates independently of the transfer drum 5, the area to which the glue is attached moves and passes through the cleaning device 81.

When passing under the cleaning device 81, the rotating disk 8
The glue adhering to the label 1 is removed completely, and the label 1 is sent back onto the path along which it passes.

As a result, the contact surface of the rotary disk 8 located on the trajectory along which the label 1 passes remains free of glue at all times, and the label 1 runs smoothly.

Since the present invention is as explained above, the following effects can be expected.

Since the floor plate on which the label is slidably transferred is configured as a rotating disk having a cleaning device, glue adhering to the contact surface of the rotating disk is removed.

Therefore, label clogging can be prevented and labels can be transported smoothly.

Exit> It can be used for various drums as long as they are used to transport labels.

<C> Labels to be transported should be limited to tag labels; glued labels may be tape-shaped labels cut into short pieces, or labels supplied stored in a label holder; Wide range of application.

As the label can be expected to be transferred smoothly, not only has the waste of conventional J:Una labels been drastically reduced, but it has also reduced the amount of glue used.
There is no need to stop the operation of the device every time you remove a stuck label (this allows for efficient operation).
