Description

[Detailed description of the invention] (Industrial application field) This invention uses a printer or the like to peel off a label with desired printing from a tape-like backing, and temporarily places the label on a label holder. The present invention also relates to a label holder device in an air-type automatic label pasting machine that adsorbs the label on a suction plate of the automatic label pasting machine and then affixes it to an article conveyed to a conveyance device.

(Prior art) Conventionally, in this type of automatic label pasting machine, prior art examples include (a) Japanese Utility Model Publication No. 1983-47947 (label pasting device), (b) Japanese Patent Application Laid-open No. 151644 (automatic labeling machine) pasting machine), etc.

The above-mentioned publication (a) discloses a label holder formed on a rough surface having unevenness, and the above-mentioned publication (b) discloses a label holder formed on a rough surface having unevenness, and the above-mentioned publication (b) has a number of shafts on the surface that contacts the adhesive surface of the label, and a number of shafts on the shaft. There is a disclosure of a configuration in which the label receiving roller is rotatable.

In both of these prior arts (a) and (b), a label is peeled off from a tape-like mount, and while the peeled label is sucked by a suction device, the label is transferred to a waiting label holder or a label holder to a suction device. This is a conveying device using an eggplant roller method.

(Problems to be solved by the invention) The above prior art (a) and (b) disclose a means for peeling off a label from a tape-like mount and transporting the label to a label holder or adsorption device that receives and holds the peeled label. has been done.

However, since an adhesive is generally applied to the back side of a label temporarily attached to a tape-like mount, when the label is peeled off, this adhesive falls into the label holder device or label conveying device as adhesive residue. If this glue scum is left unattended, the problem arises that it accumulates in these devices and prevents them from functioning satisfactorily. Therefore, in the label holder device of the present invention, the problem is how to easily remove this adhesive residue with a simple structure.

(Means for Solving the Problems) In the present invention, a label receiving member 40 facing the label peeling member 25 and having a plurality of label receiving rollers 43 rotatably mounted in the label peeling and transporting direction is attached to a support frame 4.
1, and a label holder device is provided with an outlet 45 for discharging glue residue at the bottom of the support frame.

(Function) The adhesive surface of the label peeled off from the tape-like mount is brought into contact with a large number of freely rotatable label receiving rollers 43, and the resistance to peeling and transfer during peeling is minimized by the rotating action of the label receiving rollers. Peeled off as small as possible. At the time of this peeling, a small amount of adhesive residue falls into the support frame 41. A part of this fallen glue scum is directly discharged through the outflow hole 45 provided in the support frame 41, and the other part is discharged directly from the support frame 41.
However, in such a case, it can be flowed out through the outflow hole 45 by simply washing with water.

Therefore, since the label receiving roller 43 is configured to be able to release adhesive waste, the label receiving roller 43 always rotates smoothly, and especially when peeling a label, it rotates due to the contact movement of the peeled label, thereby promoting the peeling action.

(Example) The label holder device of the present invention is suitable as a holder for large-sized labels, and will be described below with reference to the attached drawings.

As shown in Figure 1, the main body 1 of the automatic label pasting machine
The base 2 is installed on the installation plate 16, and by the action of compressed air, the vertical direction Y, the horizontal direction
The configuration allows reciprocating movement and turning movement in each direction of 90° turning Z.

In detail, the reciprocating motion in the vertical direction Y is caused by supplying and discharging air from the supply and discharge ports 4a and 4b of the air cylinder 4, which moves in conjunction with the operating rod 5 of the piston to move the body 3.
This is the vertical movement of This compressed air receives a signal from a sequence controller 32 at an air control box 33, and is transmitted from the box to a compressor 34 to the main body 1.

Reciprocation in the lateral direction It is a lateral movement.

In the Z direction of rotation, the entire head 8 is rotated through 90 degrees around the rotating shaft 11 by air flowing from the supply/discharge ports 9a and 9b to the rotating air cylinder 9.

Next, the head block 10 holding the head 8 has an operating rod 12 connected to a piston with a buffer material 13 such as a spring interposed therebetween, and a suction body with a suction pad 15 is attached to the tip of the operation rod 12. 1
4 is installed.

Next, as shown in detail in FIG.
consists of a tape-like mount 20 and a large label 18 whose adhesive surface 19 is bonded to the mount, and is wound into a roll on a supply reel 21 shown in FIG. The tape-shaped mount 20 is turned onto the board 16 by a part of the peeling member 25 consisting of a peeling pin held on the mounting board 26, and then the tape-shaped mount 20 is transferred to the board 16 by a guide roller 27 and a transfer device including a feed roller 28 and a push roller 29. By pulling the mount 20, the large label 18 is
It peels off.

Thus, the present apparatus has a configuration of the label receiving member 40 set facing the peeling member 25, and will be explained with reference to FIGS. 2 and 3.

The label receiving member 40 has a rectangular support frame 41.
A large number of shafts 42, which are set perpendicular to the feeding direction 46 of the large label 18, are mounted at equal intervals. A plurality of label receiving rollers 43 are provided on each shaft 42 in a direction 46 in which the large label 18 is fed out.
It is fitted so that it can rotate freely in the direction. Furthermore, this label receiving roller 43 has a circular side surface, and a cross-sectional side surface has an outer peripheral edge 44 that contacts a pyramidal label protruding from the center of the outer periphery.
It has a so-called Soroban bead shape, and its surface is resin-treated with a non-adhesive material such as fluorine, Teflon, or silicone resin. Furthermore, an outflow hole 45 is bored in the bottom surface of this support frame 41,
The configuration is suitable for releasing adhesive residue from the adhesive surface on the back side of the label and for cleaning the label receiving roller 43 when washing it with water.

Incidentally, reference numeral 47 shown in FIG. 1 is a mounting base for the label receiving member 40, and the structure is such that the height can be adjusted. Next, the operation of attaching a label to the target object 35 in an automatic label attaching machine equipped with the present device will be explained.

First, a printer (not shown) rotates a desired print onto the large label 18 according to a control signal from the sequence controller 32, and then a motor (not shown) rotates the feed roller 28 to print the tape-shaped backing paper 20. The printed large-sized label 18 is peeled off by the peeling member 25 due to the traction action.
Next, this large label 18 is placed on the label receiving roller 43 of the label receiving member 40 of this device with its adhesive surface 19
With its side facing, it is rotated and guided in the longitudinal direction by the outer peripheral edge 44 of the label receiving roller 43 smoothly without sticking, and is temporarily held there. This temporary holding is label placement from label peeling to standby for the large label 18 to be sucked onto a suction body 14 of an automatic label pasting machine, which will be described later.

Next, it is placed on the conveyor 30 and transported.
For example, a sensor 31 detects an object 35, such as a cardboard box in which a product is packed, and sends its output signal to a sequence controller 32. Then, in response to this output signal, the sequence controller 32 sends a control signal to the air control box 33 to
The compressor 32 is operated from the box 33,
A compression effect is applied to the air cylinder 4 of the main body 1.

Then, the adsorbent 14 is facing downward (the adsorbent 14 in Fig. 1 is turned 90 degrees and is facing sideways).
The air cylinder 4 is activated and the body 3 is lowered to a predetermined position. In synchronization with this descent, a suction action of air is applied to the suction body 14, and the large label 18 waiting on the label receiving member 40 of the device is
The suction pad 15 suctions the non-adhesive side without receiving any adhesive resistance. This adsorbent 14
The next stage of operation is performed by transmitting an output signal confirming that the label has been adsorbed to the sequence controller 32.

In this way, the large label 18 adsorbed by the adsorbent 14 is again raised to a predetermined position by the operation of the air cylinder 4. Next, the suction body 14 is rotated through 90 degrees by the operation of the rotary air cylinder 9, so that its suction surface faces the conveyor 30.

Next, by operating the air cylinder 6, the adsorbent 14 is advanced in the set direction of the conveyor 30. That is, it moves in the lateral direction X. At this time, the object 35 placed on the conveyor 30 is placed on the label receiving member 4 of the device.
The large label 18 has been moved in the lateral direction corresponding to 0 and has been carried by the adsorbent 14.
is pasted on its side.

Next, by transmitting an output signal confirming that the label has been attached to the object 35 to the sequence controller 32, the air adsorption action on the adsorption body 14 is stopped. Then this adsorbent 14
is moved back to its original position by the action of the air cylinder 6, and rotated by 90 degrees by the action of the rotating air cylinder 9, returning to its original state. In addition, the contact impact when the adsorbent 14 attaches the label to the object 35 is caused by the shock absorbing material 13.
It is also absorbed by an air shock absorber (not shown) or the like.

(Effects of the invention) As described above, the present invention provides a label receiving member 40 in which a number of label receiving rollers 43 are rotatably mounted in the label peeling and transporting direction facing the label peeling member 25.
is used as a support frame 41, and an outflow port 45 for discharging adhesive residue is provided at the bottom of the support frame, so that the support frame catches adhesive residue generated when a label is peeled off from a tape-shaped mount. At the same time, it can be discharged from the outlet, so glue scum does not accumulate.
Therefore, during label peeling, the label receiving roller always rotates smoothly and can perform a sufficient function as a label receiving member.
