Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape applicator that can be used to apply tape to the neck of a cathode ray tube.

Conventionally, when attaching cotton tape and polymeric tape to the neck of a cathode ray tube, the tape was cut to a certain length using a cutter, and then the tape was attached manually to the neck of the cathode ray tube. Ta.

Since this work is done manually, it is inefficient and the application is not uniform.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a tape application device that mechanically winds and applies a tape to an object.

The present invention is characterized by a tape supply unit that continuously supplies tape coated with adhesive, and a tape supply unit that intermittently draws out the tape from the tape supply unit and positions the tape on the surface of the tape supply unit. A tape drum that rotates intermittently, a cutter that cuts the tape fed to this tape drum into a fixed length, and two cutters that peel off the cut tape of a fixed length from the tape and hold it by themselves. It is equipped with a bow A, a roller for adhering the tape held by these two poles to the object to be wrapped, and a roller for wrapping and adhering the tape around the object to be wound. This allows the tape to be applied without using a tape.

Embodiments of the present invention will be described below with reference to the drawings.

Two types of tapes 2 and 3 are wound around a tape holder 1. One is a cotton tape, and the other is a polymer tape, both of which have adhesive coated on their inner surfaces. A brake shoe 4 is provided on this tape holder 1, and the brake is applied by the force of an air cylinder 6.

The tapes 2 and 3 are adhered to the surface of the tape drum 6 and are pulled out from the tape holder 1. At this time, in order to peel off the tape against the adhesive force of tape 2.3,
A higher tension is required. The tape drum pulls out the tapes 2, 3 from the tape holder 1 with a tension of about 5A17. When brake shoe 4 is used, when a polymeric tape is peeled off against the adhesive force, the radius of curvature R (Fig. 2) of the peeling surface becomes large, which prevents plastic deformation of the tape and prevents warping of the tape when cutting. It can be eliminated. The minimum radius of curvature Rmin that prevents plastic deformation is determined by the material of the tape used, and the appropriate braking force is determined by the air cylinder 5.
Adjust and set the air pressure using the pressure reducing valve. Furthermore, by employing the air cylinder 6, tape replacement can be facilitated. The tape drum 6 has six arms 6a, 6b, 6c, and 6d.
, 6e, 6 are arranged in a drum shape. An auxiliary pole is provided between each arm 6a-6. Surinos) 7a-7 are provided on the outside of the arms 6a-6,
A cutter 8 is inserted here to cut the tapes 2 and 3.

Two poles 10a10b are provided in the tape application unit 9 at a constant interval. This pole 10a,
10b enters inside the tape drum 6 when the tape applying unit 9 is moved to the right. The tape applying unit 9 is provided with a sponge roller 11 facing the poles 1oa and 1ob, and the sponge roller 11.
is rotated by a geared motor 12.

The tape applying unit 9 is rotated 90 degrees from the state shown in FIG. 1 so that the rollers 11 of the poles 1oa and 10b face downward, and are further lowered to face the neck portion 14 of the cathode ray tube 13.

With the poles 1oa and 1ob placed within the width of the tape drum 6 as shown in FIG. 3, the tape drum 6 is rotated intermittently (high rotation C) as shown in FIG. Therefore, cutter 8
Cut tape 3 with. 3a is the cut tape. Next, as shown in FIG.
When b is moved to the left, the tape 3a is peeled off from the tape drum 6 by the poles 10a and 10b, and the tape 3a is removed from the tape drum 6 by the poles 10a and 10b.
0b holds the tape 3a by itself. Although cut tape 2 is also held at the same time, only tape 3a will be explained.

When the tape applicator unit 9 is rotated 90 degrees and lowered, the tape 3a, poles 10a, 10 are attached as shown in FIG.
b. The roller 11 faces the neck portion 14 of the cathode ray tube.

Next, when the tape applicator unit 9 is moved to the right, the neck part 14 passes between the poles 10a and 10b, and the tape 3a is applied to the neck part 14, as shown in FIG. It comes into contact with the surface of the tape 3a.

The tape 3a can be applied to the neck 14 by rotating the roller 11 around the neck 14. In FIG. 8, the roller 11 is rotated 180 degrees, and then the
When the roller 11 is rotated 360 degrees as shown in the figure, the tape 3a is completely attached to the neck portion 14. roller 1
1 is further rotated 180 degrees and the unit 9 is moved to the left to return to its original state (FIG. 6) as shown in FIG. 11.

As described above, according to the present invention, the tape can be automatically pulled out, cut, and pasted without requiring manual labor, and work efficiency is greatly improved.
