Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label removal mechanism applicable to a label applicator.

Conventionally, many devices have been proposed that involve picking up labels one by one from a label holder using a picker, then transferring the labels to a transfer roll, and attaching labels to containers that are transferred on a conveyor.

The main mechanism is to apply glue to the label picker, which is a label picker, and roll it over the labels stored in the label holder, taking out the labels one by one using the adhesive force of the glue. Typical methods include a method in which the labels stored in a label holder are sucked out using vacuum force.

However, conventional high-speed label removal mechanisms that utilize vacuum force have the following drawbacks.

That is, the mechanism is complicated and the transport process for applying the label is long. Furthermore, since there are many transfer points for the label, there are drawbacks such as the tendency for the label to be tilted, wrinkled, and misaligned.

The present invention has been proposed in order to solve the above-mentioned conventional drawbacks, and two eccentric spur gears with different diameters are integrally formed on the lower part of the shaft of the label take-out member, and are meshed with the spur gears. By configuring the label retrieval member to rotate on its own axis on an eccentric orbit on the outer circumferential side of the picker and on a normal orbit on the outer circumferential side of the picker using an internal gear formed in the shape of a picker,
When taking out a label, the label taking-out member rolls on the label surface to adsorb and take out the label, and then, at the time of label delivery, a label taking-out mechanism is provided in which the peripheral speed is increased to transfer the label to a transfer roll. be.

Embodiments of the present invention will be described below with reference to the drawings.

(5) and (6) are formed integrally with the gearbox (1).1. In the internal gear, the spur gear (7)
or (8) are disposed so as to be in good mesh and drive the rotating shaft (4) as the rotating disk (2) rotates.

The spur gear (force) is formed concentrically with the axis of the rotating shaft (4) and meshes with the internal gear (5), and the spur gear (8) is formed concentrically with the axis of the rotating shaft (4), and the spur gear (8) It is formed eccentric to the axis of tV7 and meshes with the internal gear (6). (9) is the shaft that fixes the support (10) to the rotating disk (2), and 01) is the rotating shaft (4). It is rotatably held on the shaft (9) via a bearing. (1) The former was a label suction member that was keyed to the rotating shaft (4), and there was a label adsorption member at a suitable location on the outer periphery to take out the label. The suction pad (12a) is attached integrally, and an air inlet (+3) and a passage 0 (a) are bored therein.The suction pad (12a) also has air inlets (1, 8a). It is set up and is.

A hole 07) communicating through a circumferential groove (1, 7a) provided in 15a) is bored. 08) is a label holder that holds label 09); (20) is a transfer roll that engages with the suction pad (12a) of the label take-out member (3); 0υ is a glue roll that engages with the transfer roll (20); (2 old conveyor, (23> is a conveyor (bottles being transported on 2nd floor), (24) is a timing screw, (25+ is a sponge body fixed to the conveyor support frame 00, (27+ is a belt conveyor (2) It rotates at a speed approximately twice as fast as the drying speed. Note that X shown in FIGS. 1 and 4 indicates the locus of the rotation axis (4).

Next, the operation will be described. A drive shaft supported by a gear box (1) is driven by a drive source (not shown), and then a rotary disk (2) that is integral with the drive shaft is rotated clockwise. At this time, the label take-out member (3) revolves together with the rotary disk (2) in the opening direction, and is also integral with the rotating shaft (4) and the label suction member (1) and the label (12&). It rotates counterclockwise due to the meshing of the spur gear (force (8)) and the internal gear (5) or (61 (!) that is integrated with the gear box (1). The rotation mechanism of the label take-out member (3) at the position where the label (12a) engages with the label holder (18) and takes out the label (I) (Fig. This is done by meshing the gear (7) and the internal gear (5).

Next, to explain the relationship between the rotation mechanism and the label take-out member (3), the behavior of the label take-out member (3) in the area where the internal gear (5) and the spur gear (force mesh) (Y in Figure 4) is the suction pad (1) that was at point (b) at position (b).

Thereafter, the label take-out member (3) revolves while rotating until it reaches the position where the label (191 is held by suction).

position), the rotation that had been carried out by the meshing of the spur gear (7) and the internal gear (5) switches to the spur gear (8) and the internal gear (6), and revolves at an increased rotation speed. , move to position (E). In this case, the label removal member (3
) follows the shaft (9) as a fulcrum in order to synchronize with the meshing locus of the spur gear (8) and the internal gear (6).

When the label take-out member (3) moves to position (E), the position of the suction pad (12a) is point (E), where it engages with the transfer roll (2) (not shown in this engagement position). The vacuum source and the hole (1η are cut off by known means) and labeled (the vacuum force that attracts and holds 1ω is released).

The label (1) is easily adsorbed and held by the label suction part (not shown) of the transfer roll (20), rotates clockwise, engages with the glue roll (21), and is attached to the back side of the label (1). After the transfer roll (2 (+)) rotates, the conveyor (2 (+)) is rotated and the timing screw (241) is used to engage the bottle (c) to be transferred. Temporarily attached to the specified position of the same paragraph (2:a'41)
．． (The suction force acting on the suction portion (not shown) of the transfer roll (20) is released by known means immediately before the transfer roll (20) engages with the bottle (23).

And the bottle (23) with the label (10) on it as mentioned above.
The label (19) was completely affixed using the bell [7) and the sponge body (2 (g)), and the label (19) was transferred to the next process. The label retrieval member (3) is located at the end point position (No. 4, Figure Z) of the meshing range between the internal gear (6) and the spur gear (8).
After revolving around its axis while rotating to
5) and the spur gear (which changes into force (bearing of the label take-out member (3)) are constantly pressed in the outer circumferential direction by a means (for example, a spring) not shown, and the spur gear (7)
Or it helps meshing between (8) and internal gear (5) or (6). ) As explained above in detail, the present invention is constructed and the label is taken out by a series of rotational movements, which makes it possible to increase the speed. , which is advantageous in terms of cost. In addition, by lowering the circumferential speed of the label when it is taken out compared to the circumferential speed of the delivery section to the transfer roll, wrinkles on the label can be reduced.
Labels can be taken out without any problems such as tilting.
