Description

[Detailed description of the invention] The present invention relates to a method for attaching a label.

[B] Prior Art For example, in order to affix labels to both sides of a bottle, multiple sets of labels may be pasted between devices.

Furthermore, as a device for pasting labels on both sides of bottles and the like, there is a type of device that punches out deformed labels such as triangles and rhombuses from tape and pastes them on both sides.

[Explanation] Problems to be Solved by the Invention When a plurality of labels are attached to both sides of a bottle or the like using the above-mentioned punching/cutting type, the following two types of spacing are not the same.

(1) Distance between labels affixed to the front and back of container M (Fig. 6a) (2) Distance between container M on the conveyor and the next container M (Fig. 6
Figure b) Therefore, if the front and practical labels of the container M are punched one after another from the tape T, which is densely printed at the minimum interval C, and supplied to the container M at the same interval, both sides of one container M Even if the label can be attached to the container M, the label will be supplied before the next container M arrives, making continuous double-sided attachment impossible.

Furthermore, it is uneconomical to deploy multiple sets of affixing equipment because the equipment is bulky (and uneconomical).

The present invention was made to solve the above-mentioned problems, and is a label pasting method that allows multiple labels to be successively pasted on multiple locations on containers etc. using a single device. The purpose is to provide a method.

[C] Means for solving the problem The present invention involves cutting a tape into a size that makes up a set of multiple labels, then punching out the cut tape to produce labels, and then attaching them to containers. The present invention relates to a label pasting method in which the labels are spaced apart in between.

[2] Embodiment An embodiment of the present invention will be described below with reference to the drawings, but first a label sticking device will be explained.

(1) Description of the entire device The pasting device 1 used in the present invention has a cutting section that pulls out a roll of tape T and cuts it into a predetermined length, and a cutting section that cuts the tape into two parts, one for the front surface and one for the back surface. It consists of a punching part that is formed by punching out different types of labels, and a pasting part that takes two types of labels, widens the distance between them, and affixes them to the container.

(2) Cutting section (Fig. 1) 11 is a pull-out roller, and two pull-out rollers 1
Sandwich the tape T between 1 and pull it out one by one.

A rotary cutter 2 having a fixed blade 21 and a blade 22 protruding from the circumferential surface of a rotating drum is disposed on the transfer side of the tape T pulled out by the pull-out roller 11, and the tape T passing between the two blades is disposed. The structure is such that it can be cut into a predetermined size by rotating a rotary cutter 2.

(3) Punching section (FIG. 1) The punching section is composed of two rotating drums, an anvil drum 5 and a die drum 6.

A shock absorbing material such as rubber is attached to the outer circumference of the anvil drum 5, and a convex blade having the same shape as the outer contour of the label L is provided on the circumferential surface of the die drum 6.

On the floor surface W under the bottom of both drums 5 and 6, there is a section connecting the position where the piece cut by the rotary cutter 2 is received and the position slightly advanced from the position where punching is completed, and the circumferential surface of the anvil drum 5. Negative pressure grooves are provided in the sections connecting the drums 7 and 7, respectively.

Furthermore, suction holes are provided on the circumferential surfaces of both drums 5.6 so that the labels L and label waste can be separated and transferred.

In particular, the label waste adsorbed on the anvil drum 5 does not need to be collected by winding up, since the negative pressure is cut off immediately after passing through the negative pressure groove and the label waste can be released.

(4) Paste section (Figures 1 to 5) A pasting drum 7 is placed near the die drum 6.

For pasting, the drum 7 picks up the transported labels L by adsorption to the circumferential surface of the die drum 6 at regular intervals, and before pasting them onto the container, the drum 7 picks up the labels L transferred by adsorption to the peripheral surface of the die drum 6. Pasting is a drum whose purpose is to correct the timing.

In order to achieve the above object, the following modification means were adopted in this embodiment.

That is, as shown in FIG. 2, a plurality of sets (in the case of this embodiment, two sets) of fixed spray plates 8 and slide spray plates 9 are provided on the outer periphery of the drum 7.

[Fixed spray plate l (Fig. 2.3.5) The fixed spray plate 8 is fixedly attached to the outer periphery of the drum,
Suction holes 81 for generating negative pressure are provided in the plate surface.

In order to generate negative pressure in the suction hole 81, for example, the adhesive is attached to the floor surface W that supports the drum 7 in an area from the position closest to the surface of the die drum 6 to the area closest to the container M (hereinafter referred to as "correction area"). A negative pressure groove 82 is formed in the suction hole 81 (hereinafter referred to as "H"), and negative pressure is generated in the suction hole 81 only when passing directly above the negative pressure groove 82.

[Slide spout plate J (Fig. 2.4.5) Slide spout plate 9
is an L-shaped plate that has a suction function and a horizontal sliding function.

The slide spout plate 9 has an attachment part 92 disposed close to the circumferential surface of the drum 7, and a leg part 91 extending in the horizontal direction penetrating into the horizontal lower 1 provided at the bottom of the drum 7. .

[Sliding Mechanism of Slide Spout Plate] (Fig. 4.5) To give the slide spout plate 9 a horizontal sliding function, for example, a bottle 93 is provided protruding from the leg portion 92.

On the other hand, the attachment is carried out using a support shaft 72 erected on the bottom surface of the drum 7.
The swing arm is rotatably supported through the upper part of the swing arm.

Furthermore, a U-shaped opening lower 4 is provided at one end of the swing arm 73.
, and this open lower lower 4 is fitted over the bin 93 of the leg portion 92 and locked.

Further, a roller 75 is provided on the other end side of the swing arm 73.

Then, the roller 75 is engaged with a fixed groove cam 77 suspended from the upper part of the drum 7 using a hanging member 76.

The fixed groove cam 77 moves the slide jet plate 9 in the correction section H.
The slide jet plate 9 is shaped so as to be able to be moved forward to the upstream side until the pasting of the upper label L is completed.

[Adsorption mechanism 1 for sliding spout plate (Fig. 4) In order to adsorb and transfer the label L, a plurality of suction holes 94 are formed in the plate surface of the pasting part 91 in the same way as the fixed plate 8. A hose 95 or the like is connected to this suction hole 94, and the free end of the hose 95 is exposed and guided on the bottom surface of the drum 7.

For pasting, a negative pressure groove 96 is provided over the correction section H on the floor surface B facing the hose 95 guided under the bottom surface of the drum 7.

Therefore, only while passing through the correction section H, the slide jet plate 9
The label L can be adsorbed and transported.

Next, we will explain how to attach the label.

(1) Production of labels The label paper wound into a roll is pulled out and cut to the limit of the maximum width in the transport width direction of the label by the fixed blade 21 and the rotary cutter 2 to form a space P.

The piece P is transferred to the anvil drum 5.

B and S P are adsorbed to the anvil drum 5 and transferred.
The waste tape is cut between the convex blade of the Gui drum 6 and the elastic material, and the waste tape is adsorbed to the anvil drum 5 and released, and the punched front and back labels L are adsorbed to the anvil drum 6 and pasted. is supplied to the drum 7.

At this time, the fixed plate 8 has a receiver for the label L to be attached to the front side of the container M, and the slide spout plate 9 has a receiver for the label L to be attached to the front side of the container M.

(2) Correction of the pasting position The distance C1 between a set of labels L that are supplied to the pasting drum 7 and sucked at a constant speed as described above is determined by the relative circumferential speed of the die drum 6 and the pasting drum 7. Select by.

Each label L is adhered to the circumferential surface of the drum 7 and continues to be transferred, and the adhesive is applied to the back surface of the label L by a roller 10 provided on the outer periphery of the drum 7 in the middle.

(3) Label L attached to one container is adsorbed to fixed plate 8 after finishing the process.
is applied immediately upon contact with the front side of the container M.

Immediately after this, the slide jet plate 9 approached the fixed plate 8.
The label L contacts and is attached to the back side of the same container M at a slight interval C3, and the attachment of the label L to both sides of the container M is completed.

(4) When pasting to the next container, the gap C2 between the fixed plate 8 for pasting to the next container M is widened by the amount that the slide spout plate 9 moves forward.

Since the interval C2 is configured to match the supply interval of the containers M on the conveyor, when the next container is supplied and the label approaches the drum 7, it comes into contact with the label L adsorbed on the fixed plate 8. The label L is attached to the front side of the container M, and immediately after this, the label L is moved forward toward the fixed plate 8 and adsorbed to the slide spout plate 9 that maintains the interval C3, and the label L is attached to the back side of the same container M.

As described above, the operation of pasting labels on both sides of the containers M that are sequentially supplied is performed continuously.

[Other Embodiments 11 In the above embodiments, a case was explained in which the labels were manufactured by punching out the 11:'-space, but labels for the front side and the front side were each manufactured from one piece P and were pasted thereon. It is also possible to

[Other Embodiment 2] As another method for correcting the spacing between labels, the slide plate 9 may be attached in the direction of rotation of the drum 7 until the label L is attached on the slide plate 9. It is also possible to move backward in the opposite direction.

In short, the final label of the previous set of labels, which is a set of multiple labels,
It is only necessary to widen the interval between the labels and the first label of the subsequent set in accordance with the supply interval of each container M, and then attach the labels.

[EJ Effect Since the present invention is constructed as described above, the following effects can be expected.

(1) Attaching labels: While being sucked onto a drum and being transported, adjacent sets of labels are separated from each other and affixed to a container or the like.

Therefore, it is possible to modify the interval between labels depending on the interval at which the containers, etc. are transported, and it is possible to accurately and successively affix labels as the containers, etc. are transported.

(2) Waste tape does not need to be rolled up and collected as in the prior art, but after the label is punched out, it is separated from the label and released.

Therefore, labels can be manufactured and used economically without considering the "cutting margin" for collecting waste tape.
