Description

[Detailed Description of the Invention] The present invention relates to an apparatus for attaching a label containing the manufacturer's name, date of manufacture, etc. to the bottom surface of a plastic container such as a plastic tray.

Conventional examples of this type of label sticking device are disclosed in, for example, Japanese Patent Publication No. 53-27160 and Japanese Patent Application Laid-Open No. 50-72600.

However, such conventional labeling devices are equipped with a cutter blade and its driving means for cutting the band-shaped adhesive tape or address paper into a predetermined length, and the overall structure of the device is limited. was complicated.

Furthermore, in conventional labeling devices, as disclosed in Japanese Patent Publication No. 53-72157, for example,
Holes in the belt for suctioning and holding the label peeled off from the release sheet are formed at intervals in the label feeding direction. Therefore, if the length of the label peeled off from the release sheet in the feeding direction is relatively short, the label may be fed out between the holes of the belt and cannot be held by suction.

Therefore, the main purpose of this invention is to provide a label sticking device which has a simpler structure than the conventional one and which can suck and hold a label of any length and stick it to the lower surface of an object to be stuck. That's true.

Simply put, this idea consists of a conveyor for placing and conveying an object to be attached, such as a plastic container to which a label is attached, and a conveyor that is adjacent to the conveyor at an appropriate distance. A pasting conveyor which is provided at intervals in a direction intersecting the feeding direction and on which the objects to be pasted sent from the conveyor is placed and conveyed, and between the conveyor and the pasting conveyor. , a label peeling device is provided for peeling off the label from the release sheet on which the label is temporarily attached and allowing only the label to protrude to the tip of the sticking conveyor; , a suction device for sucking the label peeled off by the label peeling device from the spaced interval of the sticking conveyor with the adhesive layer as the upper surface, and suctioning the label to the surface of the sticking conveyor. , a label pasting device.

According to this invention, since the label is ejected from the tip of the adhesion conveyor by the label peeling device, there is no need to provide a cutter blade and its driving means as in the conventional case. Furthermore, since the labels are suction-held by the adhesion transport conveyors spaced apart in the direction crossing the label feeding direction, labels of any length can be suctioned and adhered to the bottom surface of the object. I can do it.

Hereinafter, the present invention will be explained in detail according to embodiments shown in the drawings.

FIG. 1 is a side view of the main parts of a label pasting device which is an embodiment of the present invention, and FIG. 2 is a plan view thereof.

Reference numeral 1 designates an endless annular conveyor, on which an object to be adhered A such as a plastic tray is placed and conveyed.

2 is a driving belt vehicle that rotates the conveyor 1.

Reference numeral 3 denotes an adhesive conveyor 3 adjacent to the conveyor 1 at an appropriate interval, and the adhesive conveyor 3 has an endless ring shape and is stretched in parallel to a driving belt vehicle 4 at a predetermined interval. ing. The adhesion conveyor 3 is provided in a straight line with the conveyor 1, and is used to place and convey the objects A to be adhered sent from the conveyor 1, and in this example, there are two conveyors. The belt is attached.

5 is a label peeling device provided between the transport conveyor 1 and the adhesion transport conveyor 3. As shown in FIG. 1, the label 101 is supported in a releasable manner by a highly flexible release sheet 102, and has an adhesive layer 103 formed by applying a pressure-sensitive adhesive or the like to the back surface, that is, the side of the release sheet 102. The label 101 is temporarily attached to a release sheet 102 on the side, and the label 101 is peeled off from the release sheet 102 by the label peeling device 5. That is, release sheet 1
The label 101 supported by the roller 02 is wound around a rotatably fixed supply reel (not shown) in the label peeling device 5, and is wound around the guide roller 6.
The film is then fed to the front edge of the peeling guide 7 and then to a take-up reel (not shown). In this way, the release sheet 102 supporting the label 101
While the sheet is being wound up from the supply reel and moved, as shown in FIG. Since the label 101 is made of a relatively rigid material, it is bent at the front edge of the peeling guide 7, moves in the opposite direction, and is sequentially wound up by the take-up reel. It is formed so that it moves straight as it is and is made to protrude from the tip of the adhesive conveyor 3.

As the label 101 rotates, the label 101 moves upward along with the adhesive conveyor 3 with its adhesive layer 103 side facing upward, but the side end of the adhesive conveyor 3 on the label peeling device 5 side The adhesive conveyor 3 is attracted to the surface of the adhesive conveyor 3 by a suction device 8 provided nearby.
accompany.

That is, the suction device 8 is configured so that the label 101 can be attracted to the circumferential surface of the adhesive conveyor 3 from the gap between the adhesive conveyors 3 by an air flow generated by rotating a fan (not shown). The label 101 accompanies the adhesion conveyor 3 while being attracted to it.

As a result, the adhesive of the label 101 that is attracted to the adhesive conveyor 3 and attached thereto is attached to the lower surface of the object A that is transferred by the conveyor 1 and then placed on the adhesive conveyor 3 and transferred. The adhesive layer 103 side is in contact with the adhesive layer 1 at the appropriate position on the adherend A.
The label 101 is attached to the 03 side.

The present invention is configured as described above, and the label 101 is supplied from the label peeling device 5 provided between the conveyor 1 and the adhesive conveyor 3 to the tip of the adhesive conveyor 3, and the label 101 is supplied to the tip of the adhesive conveyor 3. The label 101 is adsorbed onto the surface of the adhering conveyor 3 with its adhesive layer 103 as the upper surface, and the label 10
Since the label 101 is configured to be attached to the bottom surface of the object A, the label 101 is sequentially conveyed by the conveyor 1 while the object A is being conveyed, and the label 101 is attached to the object A.
A label 101 can be attached to the bottom surface.
Therefore, the work of attaching the label to the bottom of the object to be attached is extremely efficient, and the label can be attached to the bottom of the plastic tray etc. during the delivery process of the plastic tray etc. containing the product. Extremely convenient. Furthermore, the label can be accurately pasted without causing any misalignment of the label pasting position.

The present invention has excellent effects as described above.
