[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticker for sticking a sticker to a product or the like.

[0002]

2. Description of the Related Art Conventionally, when sticking a sticker on an article,
A method has been adopted in which a soft rubber roller is brought into contact with a seal placed on the surface of an article, and the seal is pressed while rolling the roller. However, the seal attached by this method has a tendency that the center portion is strongly pressed by the roller, but the end portion is easily peeled off because the roller force is not applied much to the end portion. Then, when a group of articles to which such a seal is attached is put together, there is a problem that the peeled ends of the seal are adhered to each other. For this reason, there is a demand for a device that can securely adhere the end of the seal so as not to peel off.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a device which can meet the above-mentioned demands, that is, a seal sticking device which can securely stick the end of a seal to an article. It is.

[0004]

The above object is achieved by the present invention, that is, the pair of left and right pinching arms 8 have their upper ends approaching each other when their lower ends are separated from each other, and conversely, have their upper ends mutually separated. A substantially central portion thereof is rotatably connected by a fulcrum shaft 15 so that the lower ends thereof come close to each other when they are separated from each other. Rollers 9 that roll toward both ends of the seal 7 while releasing the lower end of the pinching arm 8 after contacting the article to which the seal 7 is attached are attached, and the rollers 9 contact both ends of the seal 7. When the roller 9 is lowered in the state, it is interrupted between the upper ends of the left and right pinching arms 8, the upper end of the pinching arm 8 is opened, and the lower end of the pinching arm 8 is brought close to the other end to increase the pressure of the roller 9 against the seal 7. Characterized in that a wedge shaft 10 is provided. It can be solved by that seal sticking device.

It is preferable that the roller 9 used here is divided into a plurality of parts and arranged continuously in the longitudinal direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. First, the overall structure of the apparatus will be schematically described with reference to FIGS. 1 and 2. A support plate 2 is erected on a base 1 and a slide unit 3 that can move up and down is mounted on the front surface of the support plate 2. In addition, a seal sticking mechanism 4 is integrally attached to the slide unit 3, and a mounting table 5 for placing an article to which a seal is to be attached is disposed below the seal sticking mechanism 4. In this embodiment, the barrel 6 of a cylindrical writing instrument is a target article to which a seal is to be attached. After attaching the center of the seal 7 to the upper surface of the barrel 6 at another place, the barrel 6 is horizontally transferred between the seal sticking mechanism 4 and the mount 5 and is placed on the mount 5. Will be. The seal 7 has an adhesive applied to the back surface.

Next, FIGS. 3 and 4 show a main part of the seal sticking mechanism 4. FIG. The seal sticking mechanism 4 includes a pair of left and right sandwiching arms 8 whose substantially central portions are rotatably connected by a fulcrum shaft 15 and whose upper and lower ends are freely openable and closable.
have. When the lower ends are separated from each other, the upper and lower arms 8 move closer to each other, and conversely, when the upper ends are separated from each other, the lower arms 8 move closer to each other. The pinching arm 8 is configured by connecting upper and lower two members 8a and 8b, and the upper left and right members 8a thereof are connected by a spring 16. At the lower ends of the left and right sandwiching arms 8, rollers 9 made of soft rubber are rotatably mounted. In addition, a wedge shaft 10 that can move up and down with respect to the holding arm 8 is disposed above the holding arm 8. When the wedge shaft 10 is lowered, the wedge shaft 10 can be interrupted at the middle of the upper end of the left and right sandwiching arms 8.

When the shaft cylinder 6 is set on the mounting base 5, the sticking mechanism 4 is lowered together with the slide unit 3, and the roller 9 attached to the lower end of the pinching arm 8 is moved via the seal 7 to the shaft cylinder 6. Abuts the upper surface of the When the seal attaching mechanism 4 is further lowered, as shown in FIG. 5, the roller 9 rolls outward on the surface of the shaft 6 and the lower ends of the left and right sandwiching arms 8 are separated from each other. The seal 7 is attached from the upper surface to the side surface. The stopper 11 (see FIG. 2) is adjusted so that the lowering of the slide unit 3 is stopped when the roller 9 just comes into contact with both end positions of the seal 7. At this time, the roller 9 simply presses both ends of the seal 7 using the force of the spring 16. Thereafter, as shown in FIG.
0 falls. Although the upper ends of the left and right clamping arms 8 are close to each other, the lower ends of the wedge shafts 10 are interposed therebetween to separate the upper ends of the left and right clamping arms 8 from each other. Thereby, the lower ends of the left and right pinching arms 8 move in directions approaching each other. Therefore, both end portions of the seal 7 are strongly pressed against the surface of the shaft cylinder 6 by the roller 9 and securely adhered so as not to be peeled off.

As shown in FIGS. 4 and 7, the rollers 9 are divided into a plurality of parts and are continuously arranged in the longitudinal direction. The roller 9 is in close contact with the outer peripheral surface of a metal cylindrical core 12, and the core 12 is rotatably fitted to a central shaft 13. Roller 9 divided bodies 9a, 9b, 9c, 9d
Have slightly different outer diameters. Also, the core 12

That is, the meat layer is uniform. When the roller 9 is divided into a plurality of parts and the outer diameters of the divided bodies 9a, 9b, 9c, and 9d are slightly different from each other, the shaft 6 on which the seal 7 is stuck is formed.
Even when the surface of the roller 9 is slightly tapered, the outer surface of the roller 9 is more likely to contact the surface of the shaft 6 and the contact area is increased as compared with a case where the roller is continuous. And the seal 7 is strongly adhered. Also, as described above, steps 14a, 14b, and 14c are provided on the outer peripheral surface of the core 12 so that each divided body 9 of the roller 9 is formed.
When the thicknesses of a, 9b, 9c, and 9d are constant, the seal 7
When pressing is performed, the amount of compressive deformation of each of the divided bodies 9a, 9b, 9c, 9d becomes the same, so that the same pressure is applied to each part of the seal 7, and each part of the seal 7 is uniformly adhered. .

[0010]

The seal sticking apparatus of the present invention is as described above, and the lower end of the pinching arm 8 strongly presses the roller 9 by the action of the wedge shaft 10 with the roller 9 in contact with both ends of the seal 7. Therefore, both end portions of the seal 7 are securely adhered to each other, and are hardly peeled off. Therefore, when a group of articles to which the seal 7 is attached is put together, it is possible to solve the problem that the seals whose ends have been peeled off are bonded to each other. Further, when the roller 9 is divided as described in claim 2, even if the surface of the article to which the seal 7 is applied is slightly inclined, the roller 9 can easily contact the surface, and the seal 7 can be evenly and uniformly. Can be adhered to.
