Description

[Detailed description of the invention] The present invention relates to a method for transporting peelable labels.

Conventionally, there is a method shown in FIG. 6 as a method of peeling off and transporting a label stuck to a tape-shaped mount.

That is, in a device that pulls out a label (L) wound into a roll by the rotation of a drawer drum (A),
A peeling plate (B) with an acute intersecting surface is placed in the middle, and the backing paper (C) of the label (L) is brought into contact with this peeling plate (B) and pulled out, and the label is peeled off from the stand @ (C). The non-adhesive surface of (L) was adsorbed and transferred by the negative pressure of a suction drum (D) placed near the peeling plate (B).

At this time, a curved guide (E) is placed around the suction drum (D) through which the label (L) is delivered to prevent the label (L) from accidentally flying out.

However, the transfer method described in section t has the following problems.

<A> The label (L) is transferred with the adhesive surface facing outward, so that it is easily adhered to the inner wall surface of the guide (E).

In particular, as there has been a recent demand for faster transport of labels (L), labels (L) are becoming more and more likely to separate from the suction drum (D), and jamming occurs when the negative part of labels (L) adheres. However, continuous and smooth transfer of the belt becomes impossible.

Exit> One label (L) is Ji1? When you wake up,
All subsequent large groups of labels (L) also result in jamming.

Therefore, not only a large amount of labels (L) are wasted, but also the operation of all devices related to the transport of labels (L) must be stopped each time.

The present invention has been made to improve these points, and provides a label transport method that has a simple structure and can transport labels smoothly and reliably even during ultra-high-speed operation. With the goal.

Next, before describing embodiments, each part of the apparatus according to the present application will be described first.

B. Transfer Drum The transfer drum (1) is a drum configured to be rotatable around a rotating shaft (11).

The transfer drum (1) is a transfer drum (1) as shown in FIG.
) is a drum for sucking the non-adhesive surface of the peelable label (3) peeled off from the mount 31) and directly pasting it onto the article (M).

Therefore, there are many suction holes (1) on the circumference of the transfer drum (1).
2) At the bottom of the transfer drum (1), there is a section from the position closest to the peeling body (2) to the position where it contacts the article (M) sent from the tangential direction of the transfer drum (1). A negative pressure groove (13) communicating between the two is formed.

One end of the negative pressure groove (13) is connected to a vacuum pump or the like, and negative pressure is generated in the negative pressure groove (13).

In other words, the suction hole (1
2) The configuration is such that negative pressure is generated only in 2).゛〈mouth〉
The non-neck guide non-neck kite (5) is composed of a large number of rotating bodies to be adhered to, for example, non-adhesive rollers (51). The outer surface is made of non-adhesive material to prevent contact with the label (3). Ii+te to form a non-adhesive surface (53).

A curved support plate (54) is disposed near the circumferential surface of the transfer drum (1) so as to extend from the position where the label (3) is transferred in the direction in which the label (3) is transferred.

The shaft (1) of the transfer drum (1) is located inside this support plate (54).
')''1) Each non-adhering roller (51) is rotatably supported and provided parallel to the direction.

That is, the non-adhesive roller (51
) can guide the label (3).

In other words, in the non-necked guide (5) according to the present application, if centrifugal force is exerted during the transport of the label and part of the guide (3) suddenly pops out,
Rather than allowing surface contact with the guide plate formed from a smooth surface as in the past, even if the label (3) pops out, it makes line contact with the label (3) to minimize the contact area and proactively The aim is to reduce the frictional resistance and prevent labels from sticking.

<C> Other Embodiments 1 As shown in FIG. 4, it is important to use a non-necked guide also in the case of a claw fq drum (6) having claws (61) on the circumferential surface.

The purpose of adopting the drum with claws (6) is to not require much accuracy in the peeling position of the peelable label and the position of transfer to the drum (6), and to attach the label to the container in the most accurate position. It's for a reason.

Therefore, after peeling, the label is not sucked by the drum (6) immediately, but is left in a free condition, and then the claw (61) follows (
This is a method for correcting errors and performing accurate feeding.

The label (3) under such rough conditions is likely to fly out from the guide side due to the centrifugal force caused by the air flow around the drum (6), but in such a case, the delinquent guide of the present invention becomes an essential structure.

Other Example 2 The non-stick rotating body constituting the non-neck guide (5) has a spherical shape as shown in Fig. 5 and is a hard-to-stick ball (5'
Even if a large number of balls 1') are arranged rotatably, or a mixture of a-ra and balls is arranged, the same effect as in the embodiment described above can be expected.

In this case, the label (3) and the ball (51') are in point contact, which further reduces the possibility of adhesion.

Next, the transfer method will be explained.

<A> The drawer drum (4) is rotated in such a state that the release tape-like mount (31) of the label is folded back with the release member (2).

The mounts (31) located between the drums are sequentially pulled out by the rotational frictional force of the drawer drums (4).

As a result, the peelable label (3) cannot be bent along with the backing paper (31) at the position of the peeling body (2), and is peeled off from the backing paper (31) with the adhesive surface facing toward the hard-to-adhesion guide (5).

<Open> Transport of the label The tip of the peeled label (3) reaches the circumferential surface of the transport drum (1) which continues to rotate.

At this time, in the transfer drum (1), negative pressure is generated in the suction holes (12) directly and to the negative pressure groove (13), and the label (3)
The non-adhesive surface of the paper is successively picked up and the transfer continues.

(kuha) If a part of the label (3) continues to move away from the circumferential surface of the transfer drum (1) against the suction force of the suction hole (12), the separated part of the label (3) will pop out. The adhesive surface is a non-reflective material (51)
in direct contact with the surrounding surface.

However, even if the label (3) comes into contact with the non-targeted rotating body (51), the non-adherence surface (5
3), and since the two are not in surface contact but in line contact, there is no possibility of adhesion.

As a result, the label (3) is prevented from being bent more than necessary due to its own strength, that is, its stiffness.

Therefore, the label (3) does not turn over and the non-remarkable roll (5
1) or away from the rotary body (51) and is pulled back to the circumferential surface of the transfer drum (1) and then returned to the transfer drum (1).
7) is transferred while being attracted to the suction hole (12).

Labels (3) that are attracted to the transfer drum (1) and continue to rotate
passes over the tail end of the negative pressure groove (13) and the suction hole (12)
The negative pressure is cut off and the object (M) is stuck to the object (M) approaching from the tangential direction.

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

Kui〉While the label is being transported, there is no need to worry about it sticking even if the adhesive side of the label comes into contact with the non-adhesive rolling material as we have placed a number of non-stick rolling bodies with anti-adhesion treatment on the periphery of the labels. do not have.

Therefore, the labels are transported smoothly without jamming.

Even if the <mouth> label comes into contact with a non-targeted object, the frictional resistance generated between the two is very small, so there is no fear that the label will bend due to its own stiffness.

Therefore, labels can be transported at high speed.

・TEC> Rather than using a specially constructed drum to prevent label jamming, simply placing a hard-to-stick guide on the circumferential surface of the label transport surface treated with a known method to prevent jamming. It is.

Therefore, the ItH construction is simple and can be easily adopted into existing equipment.
