Description

[Detailed explanation of the idea] The present invention relates to a labeling device.

For example, it is conceivable that the label peeled off from the backing paper by a peeling plate of a label issuing machine is supported by a feed roller and a leaf spring that comes into contact with the roller, and fed to the label holding section.

However, with this structure, the adhesive on the back side of the label that has adhered to the surface of the roller further adheres to the leaf spring, and the adhesive that has adhered to the leaf spring is then peeled off and the adhesive on the back side of the label that has been sent in is peeled off. There is a risk that the attached adhesive may cause the label to adhere to a guide plate or the like, resulting in the label not being properly fed into the label holding section.

Further, since the leaf spring is in contact with the roller surface, there is also the problem that the resin material coated on the roller surface is abraded.

Therefore, the present invention provides a label sticking device that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a label issuing machine, and 2 is a label sticking device attached to the front of the issuing machine 1, which extends horizontally from the issuing machine 1.

3 is an adhesive box, and inside the box 3 is a partition plate 4.
It is divided into large room 5 and small room 6.

Reference numeral 7 denotes a label holding port formed in the bottom plate 3a of the box 3 at the lower part of the small chamber 6, and 8 is a fan disposed in the large room 5, and the air outlet 8a of the fan 8 is connected to the It penetrates through the partition plate 4 and is located above the label holding opening 7.

Reference numeral 10 denotes a pair of gates that open and close the air blowing path connecting the holding port 7 and the air blowing port 8a, and when the gates 10 are in the horizontal state shown in FIG. It is divided into a lower chamber 6b and the air blowing path is closed.

Although not shown, the upper chamber 6a communicates with the outside air via a communication hole.

12 is a communication hole that communicates the lower chamber 6b formed in the partition plate 4 with the large room 5; 16 is a disk fixed to the rotating shaft 9 of the gate 10; and 17 is a hole whose lower end is near the outer periphery of the disk 16. When the connecting rod 17 is pulled upward from the state shown in FIG. 1 by a driving means such as a solenoid, the gate 10 rotates 90 degrees and stands upright, and the air blowing path is opened, and the air outlet 8a of the fan 8
The air blown out reaches the label holding port 7.

Reference numeral 21 denotes a label conveying device provided under the box 3, which includes a guide plate 22 fixed to the bottom surface of the box 3, and a belt conveyor 23 provided close to the bottom surface of the guide plate 22.
The belt conveyor 23 has a pair of mutually parallel frames 35 fixed to the lower surface of the box 3, a small diameter roller 36 whose both ends are rotatably supported by the frame 35 near the label holding opening 7, A support shaft 37 whose both ends are rotatably supported by the frame 35 in the vicinity of the label issuing machine 1, a large diameter roller 38 having four annular recesses 38a fixed on the support shaft 37, and the large diameter roller. 38 annular recesses 38a and the small-diameter roller 36, and fixed on the bottom plate 3a of the box 3, the It has a drive motor 43 that rotates the support shaft 37 and the large diameter roller 38 at high speed (approximately 100 m/min).

38b is the three annular grooves formed between the respective annular recesses 38a of the roller 38, 44 is a cross beam that extends between both frames 35 and fixed with screws 66, and 67 is the main body 67a. 44, and three legs 67 extending obliquely downward from the main body 67a.
The tips of the legs 67b are inserted into the annular grooves 38b, and the tips of the legs 67b and the annular grooves 38b are respectively inserted into the annular grooves 38b.
A slight gap is formed between the bottom surface and the bottom surface.

The outer circumferential surface of the roller 38 is coated with a material having a low coefficient of friction, such as silicone-based or nitrogen-based resin material.

45 is a peeling plate provided in the label printing machine 1, 46 is a label guide stand disposed between the peeling plate 45 and the large diameter roller 38, and 49 is used to print weight, unit price, price, etc. on the label 25. The printer drum 50 is a hammer for pressing the label 25 onto the drum 49.

Reference numeral 24 denotes a stopper for positioning the label 25 carried into the label holding port 7, which is mounted from an L-shaped plate, and its horizontal portion 24a is screwed to the bottom surface of the box 3.

Reference numeral 26 denotes label support bars arranged at regular intervals within the holding port 7.

Reference numeral 68 denotes a pair of guide plates fixed to the horizontal portion 24a of the stopper 24 with the label holding opening 7 in between.
The label 25 is arranged in the shape of a "C" and guides the label 25 to a position directly below the holding port 7.

The operation of the above structure will be explained.

For example, in a weight value marking device, when a weight is weighed on a scale, a predetermined label 25 is pressed against a printer drum 49 by a hammer 50 in the label printing machine 1 based on the weighed value, and the label 25 is stamped with weight, unit price, and price. etc. are printed.

Next, when the backing paper 51 and the label 25 are fed in the direction of the arrow, the label 25 is peeled off from the backing paper 51 by the peeling plate 45, and the end of the label 25 passes over the guide stand 46 and touches the large diameter roller 38 and the leaf spring. It is inserted between the leg 67b of 67.

Then, since the large-diameter roller 38 is rotating at a high speed, the label 25 is wound up at a high speed and is conveyed at a high speed between each belt 39 and the guide plate 22 in the direction of the arrow, into the holding port 7. It enters, hits the vertical part 24b of the stopper 24, and is stopped in the holding opening 7.

By the way, since the tip of each leg 67b is inserted into the annular groove 38b, the label 25 is pressed against the large diameter roller 38 by each leg 67b.

Therefore, the label 25 is attached to the large diameter roller 3 rotating at high speed.
8, it is reliably sent out in the direction of the arrow.

Also, since the tip of each leg 67b does not touch the bottom of the annular groove 38b, the adhesive on the back side of the label 25 is not in contact with the annular groove 38b.
The adhesive hardly adheres to the bottom surface of b, and even if the adhesive adheres to the bottom surface, the adhered adhesive will further spread to the legs 67.
b It does not adhere to the tip.

Further, even if the label 25 is conveyed diagonally toward the holding port 7, the corner of the label 25 will hit the guide plate 68 and be corrected, and the label 25 will be directly below the holding port 7 as shown by the imaginary line in FIG. brought into position.

Next, when the label 25 is in the holding port 7, the gate 10 is horizontal and the air blowing path is blocked, and the suction port 8b of the fan 8 connects the holding port 7 and the communication hole 12.
Air is sucked through the fan 8, and the sucked air is blown out of the pasting box 3 from the blow-off port 8a of the fan 8 through the upper chamber 6a of the small room 6.

Therefore, as mentioned above, the label 2 that has entered the holding port 7
5 is suctioned and sticks to the bar 26, and is suctioned and held within this holding port 7.

Next, the product 28 is brought under the holding port 7, and the connecting rod 17
}When raised, the gate 10 rotates 90 degrees and stands upright.

Then, the air blown from the outlet 8a of the fan 8 is blown toward the holding port 7, and the blown air causes the label 25 inside the holding port 7 to fly in the direction of arrow C, and the product 28 is It can be pasted at a designated location.

As described above, according to the label sticking device of the present invention, an appropriate number of annular grooves are formed at appropriate intervals on the feed roller that sends out the peeled label toward the label holding section, and the label is attached to each of the annular grooves. Since the presser member is inserted, the label peeled off from the mount by the peeling plate is pressed against the roller by the presser member.

Therefore, the label can be reliably sent out toward the label holding section by the roller.

In addition, in this case, since there is a slight gap between the presser member and the inner peripheral surface of the annular groove, the adhesive on the back of the label hardly adheres to the inner peripheral surface of the annular groove. Even if the adhesive adheres to the surface, the adhered adhesive will not further adhere to the pressing member.

Therefore, it is possible to completely eliminate the accident in which adhesive adheres to the surface of the label and the label is adhered to a guide plate or the like as in the conventional example mentioned at the beginning.

Furthermore, the roller surface is not worn away by the pressing member.
