Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a label sticking device of a type in which a label with a pressure-sensitive adhesive peeled from a peeling mount is flown onto an adherend by air to stick the label.

2. Description of the Related Art Conventionally, this type of device is constructed as shown in FIG. The strip-shaped release liner 2 with a label drawn from the supply reel 1 passes between the platen roller 3 and the thermal head 4, and passes through the corner 6 of the acute-angled piece 5 and the take-up roller 7
When the peeling mount 2 is wound around the peeling mount 2 with tension applied to the peeling mount 2 and the peeling mount 2 is wound by the winding roller 7, the label 8 is gradually peeled off at the position of the acute angle piece 5 and pushed out. Immediately before the acute-angled piece 5, the air supply / exhaust port 10 of the air supply / exhaust box 9
The label 8 pushed out is adsorbed and held on the supply / exhaust port 10 during intake in the direction indicated by the arrow A. At an appropriate timing, the air supply / exhaust box 9 stops the intake in the direction of arrow A and executes the exhaust in the direction of arrow B to attach the label 8 adsorbed and held in the air supply / exhaust port 10 to the adherend.
It is made to fly toward 11 and attached to the upper surface 12 of the adherend 11.

In addition, in such a configuration, as shown in FIG.
When the adhesive on the back surface of the label 8 is squeezed out on the rear end face C as indicated by D, the rear end of the label 8 is stuck to the release liner 2 by the squeezed adhesive. Even if the air supply / exhaust box 9 is switched to the exhaust state, the label 8 cannot be properly flown.

In order to solve such a problem, Japanese Utility Model Laid-Open No. 59-115710 discloses a configuration as shown in FIGS. 8 and 9. Components having the same functions as those in FIG. 6 will be described with the same reference numerals.

Here, a slide body 13 that can move back and forth is provided at the air supply / exhaust port 10, and the electromagnetic solenoid 14 is driven in a state where the issued label 8 is adsorbed and held on the slide body 13 and is shown in FIG. As described above, it is considered that the sliding body 13 is moved in the direction away from the acute-angled piece 5 (direction of arrow E) to peel the rear end face of the label 8 from the peeling mount 2.

Problems to be Solved by the Invention In the configuration shown in FIGS. 8 and 9 as described above, the label 8
When the adhesive force of the rear end to the release liner 2 is smaller than the label suction holding force of the slide body 13, the label 8 can be completely separated from the release liner 2 by moving the slide body 13. When there is a large amount of sticking out, the rear end surface C of the label 8 remains adhered to the release liner 2 even if the sliding body 13 moves, and the label 8 cannot fly correctly.

It is an object of the present invention to provide a label sticking device that can separate a label completely from a release liner so that the label can fly properly even when the adhesive is often squeezed out to the rear end surface of the label. To do.

Means for Solving the Problems The label sticking device of the present invention winds a release liner with a label through a corner of an acute-angled piece, and peels an adhesive label from the release liner at the position of the edge of the acute-angled piece. The issued adhesive label is adsorbed and held at an air supply / exhaust port opened near the acute-angled piece, and the adsorbed and held adhesive label is ejected from the air supply / exhaust port to fly toward an adherend. Along with the supply / exhaust port and the acute-angled piece, a fixed protrusion whose lower end extends below the corner of the acute-angled piece is provided.
In addition, it has the flexibility of deforming by contacting the protruding piece with the protruding body attached to the fixed side and the adhesive label attached to the lower part of the protruding piece and passing under the protruding body to the air supply / exhaust port. It is characterized in that it is composed of a tape-shaped body.

Action According to this configuration, the label peeled off from the release liner at the corner of the acute-angled piece and pushed out is gradually issued after passing through the lower end of the protrusion, and when it is issued to some extent, the label that has been directed downward until then. The tip is attracted to the air supply / exhaust port and bends upward. As a result, the label is adsorbed and held on the air supply / exhaust port. When the label is sucked and held by the intake / exhaust port, the label between the protrusion and the acute-angled piece is subjected to the elastic force (strength of the waist) of the label itself, and the rear end surface of the label is separated from the release liner. At this time, the rear end of the label generates a force that rotates downward with the lower end of the protrusion as the fulcrum due to the strength of the user's waist, and this elastic force overcomes the adhesive force of the adhesive that has leaked out. The label is completely separated from the release liner. In addition, even though the protrusion is fixed, since the lower part of the protrusion is made of a flexible tape-like body, the tape-like body comes into contact with the adhesive label and is elastically deformed, so that the protrusion is substantially The protrusion length naturally changes, and fine adjustment of the attachment position of the protrusion is unnecessary.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. It should be noted that components having the same functions as those of FIGS. 6 to 9 showing a conventional example are designated by the same reference numerals and described.

1 and 2 show the basic construction of the present invention. Air supply / exhaust port 10
And the acute-angled piece 5 are provided with a projection 15 whose lower end extends downwardly from the corner 6 of the acute-angled piece 5 by a length d. Protrusion
The upper end of 15 is screwed to the air supply / exhaust box 9. In addition, at least the tip of the protrusion is surface-treated with ethylene tetrafluoride or the like, which has excellent surface releasability.

With this configuration, the tip of the label 8 peeled from the release liner 2 by the acute-angled piece 5 gradually extends forward while being pushed downward by the protrusion 15 as shown by the phantom line in FIG. Since the suction force from the air supply / exhaust port 10 acts, when the issuing length of the label 8 becomes long to some extent, the leading end of the label 8 is adsorbed and held by the sliding body 13 as shown by the solid line in FIG. Further, when the rear end of the label 8 is peeled off from the release liner 2 and the rear end face of the label 8 passes through the corner 6 of the acute-angled piece 5 to be separated from the release liner 2, the label 8
Even if the adhesive protruding from the rear end face C tries to prevent the label 8 and the release liner 2 from being separated, the elastic force of the label itself [waist The strength of the waist causes the label 8 to overcome the adhesive force due to the adhesive at its rear end and pivot downward as shown in FIG. Separated from 2. Then, as shown in FIG. 3, after the sliding body 13 is moved, it is flown onto the adherend 11.

In the state shown in FIG. 1, even if the label 8 does not change to the state shown in FIG.
In addition to the peeling force of the label 8 due to the strength of the waist, the peeling force caused by the movement of the sliding body 13 is added as shown in FIG. 3, and the label 8 can be completely separated from the peeling mount 2. .

4 and 5 show the actual structure of the projection 15. In the above description of the basic configuration, the separation performance is affected by the size of the length d of the protrusion 15, which requires fine adjustment. However, by configuring the protrusion 15 as in the present invention, The adjustment can be simplified.

As shown in FIG. 4, in this embodiment, the projection 15 has a metal plate 16
And flexible tape-like material attached to the tip
As shown in FIG. 5, the tape-shaped body 17 comes into contact with the label 8 and is elastically deformed in the label feeding direction [direction of arrow F] to change the effective length d. The tape-like body 17 is made of a material such as ethylene tetrafluoride having a good peeling property, and is made of ethylene tetrafluoride having a good peeling property. It is adjusted to have the proper elastic force to act. Therefore, the alignment error of the projection 15 can be absorbed by the deformation of the tape-shaped body 17, and the projection can achieve the desired performance only by performing simple alignment.

In each of the above-described embodiments, the sliding body 13 is attached to the air supply / exhaust box 9, but as shown in FIG. Body 15
By providing, almost the same effect can be expected.

As described above, according to the present invention, a protrusion whose lower end extends below the corner of the acute-angled piece is provided between the acute-angled piece and the air supply port that holds the adhesive label. A tape having the protrusion attached to the fixed side and a flexible tape which is attached to the lower part of the protrusion and is deformed by contact with an adhesive label that passes under the protrusion and moves to the air supply / exhaust port. Since it is composed of a strip, it is possible to completely utilize the elastic force (strength of the waist) of the adhesive label itself to completely separate the rear end surface of the adhesive label from the release liner, allowing the adhesive label to fly correctly. It is possible. In addition, even though the protrusion is fixed, since the lower part of the protrusion is made of a flexible tape-like body, the tape-like body comes into contact with the adhesive label and is elastically deformed, so that the protrusion is substantially The protrusion length naturally changes, and fine adjustment of the attachment position of the protrusion is unnecessary.
