Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a label adhering head that adsorbs a label and affixes it to an object. Regarding the application head.

(Prior art) In the conventional label pasting machine, as shown in Fig. 6,
In order to peel off the label 103 temporarily attached to the release paper 101 from the release paper IQI, a release plate 105 with an acute-angled tip is provided, and when passing the front edge of the release plate 1-105, the The path suddenly changes, and the release paper 101 is highly flexible, so it is bent at the front edge of the release plate 105 and moves in the opposite direction, and the label 103 is made of a relatively rigid material, so it cannot be peeled off. It is formed so that it is peeled off from the paper 101, goes straight, and directly projects onto the main surface of the adherend 107, which is placed on the conveyor 109 and transported.

(Problem to be solved by the invention) However, in the conventional label pasting machine, the release paper 10
1, that is, the speed at which the label 103 is fed out, and the speed at which the object to which the label 103 is attached is placed on the transport conveyor 109 and sent (is likely to occur). Furthermore, due to fluctuations in the load applied to the label 103, etc., there is a high probability that the label 103 will be misaligned at the affixing position or wrinkles will occur in the affixed label. When the label 103 is long, the above-mentioned misalignment and wrinkles become more noticeable.

Therefore, the main object of the present invention is to provide a label suction type application head that can suppress the occurrence of misalignment and wrinkles even when a long label is attached.

(Means for Solving the Problems) The present invention is provided at a portion where the labels peeled off by the label peeling means are sequentially fed out, and in which the labels are peeled off by the label peeling means, and the label is peeled off by the label peeling means. a head body that is rotatably fixed so that the tip thereof is displaced toward the kimono, and has a label adsorption surface formed on the main surface following the tip, which adsorbs the label fed out from the label peeling means; A label adsorption type application head including an actuator for rotating the head main body, which is attached at a position apart from the pivot point, and an application roller rotatably fixed near the tip of the head main body. be.

(Function) According to the present invention, the head body is rotatably fixed around the pivot point formed near the rear end, and the rotation actuator is attached to the head body at a position away from the pivot point. As a result, the tip of the head body is displaced about the pivot point toward the object to be adhered.

(Effect of the invention) According to the invention, as a separate member from the label peeling means,
Since the pasting head is formed at the part where the peeled labels are sequentially fed out, there is a difference between the speed of movement of the release paper to which the label is temporarily attached and the speed of movement of the object to be pasted placed on the conveyor. There is no need to take this into account, and the label peeled off by the label peeling means is once adsorbed by a label adsorption type application head, and the application head is operated in accordance with the moving speed of the object to be applied that is sent by the conveyance means. I can do it. Therefore, there is no need to take into account the movement speed of the release paper, the load variation due to the label during peeling, etc. In addition, the labels adsorbed by the applicator head are sequentially moved from the applicator head using a force smaller than that required to peel the label from the release paper in accordance with the moving speed of the object to be adhered. It can be rolled out and pasted. Furthermore, since a pasting roller is rotatably fixed near the tip of the head body, this pasting roller can press the main surface of the label onto the surface of the object to be pasted. It is possible to prevent misalignment or wrinkles due to changes in load, etc.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Example) FIG. 1 is a perspective view of a pasting head that is an example of the present invention.

FIG. 2 is a front view of the embodiment shown in FIG.

Figure 3 is a side view of the embodiment in Figure 1.

FIG. 4 is a bottom view of the embodiment of FIG. 1.

This application head 10 includes a head main body 12.

The head main body 12 is rotatably fixed to a label applicator (not shown) near its rear end with a pivot 14 forming a pivot point, and rotates around this pivot 14 to attach the object ( The tip is configured to be displaced toward A).

A label suction surface 18 that suctions a label 16 peeled off by a label peeling means, which will be described later, is formed on the main surface following the tip of the head body 12.

A plurality of suction holes 20 are bored in this label suction surface 18, and these suction holes 20 are communicated with a suction hole 22 formed in the body of the head main body 12, and this suction hole 22 is The suction hole 2 is opened at the rear end of the head body 12.
2 and a pipe to a suction device (not shown).

The head body 12 of the application head 10 has an actuator 2 for rotating the head body 12 at a position away from the pivot 14, that is, at a portion near the tip of the head body 12.
4. For example, the tip of a movable element such as a cylinder or a solenoid is fixed, and the head main body 12 is formed to be displaced downward about the pivot 14 by the operation of the rotation actuator 24.

A pasting roller 26 is located near the tip of the head body 12.
It is fixed with a shaft 28 so as to be rotatable about the shaft 28.

Next, the label peeling means will be explained.

The label 16 is temporarily attached to a release paper 32 with an adhesive layer 30 formed on its back surface, and this release paper 32
The label 16, supported by It is fed and sent to a take-up reel (not shown). In this way, while the release paper 32 supporting the label 16 is being wound up from the supply reel and moving, as shown in FIG. The flap is suddenly changed, and the release paper 32, which is highly flexible, is bent at the front edge of the release plate 34, moves in the opposite direction, and is sequentially wound up on a take-up reel. However, label 16
Since it is made of a relatively rigid substance, it is peeled off from the release paper 32, goes straight, and is projected onto the lower surface of the label suction surface 18 of the head body 12.

Subsequently, the operating state of this pasting head 10 will be explained.

As described above, when the label 16 is attracted to the label attraction surface 18, the rotation actuator 24 is actuated, and the second
As shown by the arrow in the figure, the head main body 12 is rotated downward about the pivot 14, and the object to be adhered (A), such as a package, which is placed on the upper surface of the belt of the conveyor 36, for example, a belt conveyor. The tip of the label 16 is brought into contact with the adhesive surface of the label 16. At this time, when the object to be pasted (A) reaches a suitable pasting position, the bottom surface of the pasting roller 26 formed at the tip of the head main body 12, that is, the label 16
If the vicinity of the tip of the label 16 is brought into contact with the surface of the object (A), the tip of the label 16 will be located at an optimal position.

Then, the object to be adhered (A
) moves, while being pressed by the pasting roller 26, the adhesive layer 30 of the label 16 causes the label 16 to be successively pasted onto the surface of the pasted object (A).
) will move.

In this embodiment, the peeling plate 34 is oriented in a direction perpendicular to the longitudinal side of the head body 12 so that it is protruded from the longitudinal edge of the label 16 toward the label suction surface 18 of the head body 12. It is formed.

On the other hand, in the embodiment shown in FIG.
4 is provided on the rear end side of the head body 12, and a label 16 is provided on the rear end side of the head main body 12.
It is formed so as to protrude from the end side toward the label suction surface 18 of the head main body 12.
