Abstract

PURPOSE:To make the abrasion of edge part easy, by a method wherein the edge part of dies, punching out adhesive tape, is extruded from a punch stand, the edge part of dies, punching out adhesive tape, being extruded from the punch stand and the punch, punching out the tape, is provided by inserting it into the mold opposing against its edge part in the processing apparatus punching out the adhesive tape and connecting a pair of tapes. CONSTITUTION:When a punch 19 moves downward by driving a compressor, the sliding board 21 connected with the punch 19 descends by being guided with a pair of guides 20. At the same time, the tip of punch 19 is guided with a mold 16 and inserted into it. At that time, the adhesive tape 15 is punched out with the punch 19. Thereafter, the punch 19 further descends and pushes the punched out adhesive tape on the joint between the magnetic tape 12 and the leader tape 13 and adheres them. Because the edge part 17 extrudes from the board surface of punch stand 11, the edge part 17 can be easily abraded.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a tape processing device that punches out adhesive tapes and connects a pair of tapes.

2. Description of the Related Art Conventionally, there is a tape processing apparatus of this type that connects a leader tape to a magnetic tape, for example. In FIG. 1, reference numeral 1 denotes a punching table 1, on which a die 2 for punching adhesive tape is formed, and one edge of this die 2 is ground to form a blade part 3. Punching table 1 excluding this blade part 3
An uneven surface 4 is formed on the plate surface of the punching table 1 by using means such as corrosion processing so that the adhesive tape can be easily peeled off from the plate surface of the punching table 1.

A punch 5 is provided to face the die 2 of the punching table 1, inserting the die 21 and punching the adhesive tape into a rectangular shape. The punch 5 can be directly slid on the guide 6, and the scissors 6 regulate the punching direction of the punch 5.

Further, a single-shaped id 7 for guiding the tip of the punch 5 to the blade portion 3 is provided facing the die fj12. This punch 5 is connected to a compressor and is reciprocated in the direction F in the figure.

In this case, the blade part 3 of the die type 2 and the uneven surface 4 are formed on the same plane, so it is technically difficult to polish the blade part 3 or only the blade part 3. However, there were drawbacks that required skill.

Further, since the adhesive tape sticks to the entire 9 part 3 and the uneven surface 4, a considerably large tension is applied to the tape itself when the adhesive tape is peeled off. Therefore, the punched part of the tape must be able to withstand this tension.

This required the use of wide adhesive tape, which was uneconomical.

Furthermore, since the punch 5 is held slidably on the guide 6 at the sliding part 6a, the sliding movement of the punch 5 cannot be improved unless the size of the fit between the punch 5 and the guide 6 is slightly increased. Since this is not possible, there is a drawback that the axis of the punch 5 may shift. In this way, when the axial center runout of the punch 5 is taken into consideration, the diameter of the die mold 2 must be set larger than the cross-sectional shape of the punch 5. Therefore, the gap between the die 2 and the punch 5 becomes large, and the adhesive tape becomes difficult to cut.

This #4 was made to overcome the drawbacks described in ): The die-shaped blade part for removing the adhesive tape is made to protrude from the punching table h), and the die is opposed to this part 9. The purpose of this project is to provide a tape processing device that is equipped with a punch that punches out adhesive tape by inserting it into a mold, and that allows easy grinding of eight parts.

Hereinafter, referring to page 1.4, we will explain the central aspect of this invention and an example. , Figure 2 (Here, 11 is a punching table with 14 running heads for the magnetic tape 12 and lead tape 13, and the adhesive tape 15 is placed approximately in the center of the punching table to cut out the desired cedar. 6. Pass through the die 4 fl l 6 to form a cylindrical shape, and make one opening (shown in the figure 'F@) face the 4 running paths formed by the running base 14i of the winder, for example. The other opening of the blade 16 is made to protrude from the plate surface of the punching table 11 as shown in the third t-1 to form a blade part 17.The adhesive tape 15 is placed on the side of the blade part 17 at a predetermined pitch. In addition, an air supply port 18 is provided around the blade part 17 to supply air for peeling the adhesive tape 15 from the punching table 11 and the blade part 17.

On the other hand, a punch 19 that is inserted into the die 16 and punches the adhesive tape 15 into a desired shape, for example, a rectangular shape, is provided opposite the blade part 17, and this punch 19 is connected to the compressor 4 and driven back and forth in the north direction in the figure. . At this time, the punch 19 is fixed to a sliding plate 21 that is slidably provided on a pair of guides 20 and 20 to regulate the punching direction, and the punch 19 is adjusted so that the punch 19 matches the die mold 16. The one-shaped guide 22 that guides the tip of the blade to the die 116 is
17 are provided facing each other.

Next, the operation of this invention will be explained. When the punch 19 is moved downward in the drawing by the pressure 45, the sliding plate 21 connected to the punch 19 is guided by a pair of guides 20, 20 and lowered. At the same time, the tip of the punch 19 is guided and inserted into the die 16 by the guide 22.

At this time, the adhesive tape 15 is punched out by the punch 19. After that, the punch 19 further descends and punches 811.
An adhesive tape punched out at the joint between the air tape 12 and the lead tape 13 is pressed and adhered to the 111 which penetrates through and is located below.

After the punch 19 reaches the lowest position, it is pulled upward in the drawing by the compressor. At this time, as shown in FIG. 4, since the adhesive tape 15 is attached to the top surface of the blade 417 and the plate surface of the punching table 11 except for the periphery of the blade part 17, a sealed gap is created around the 8 part 17. kf) S occurs. Supply air to this void person-#
Air is sent from 18. This air pushes the adhesive tape 15 in the opposite direction and peels it off from the punching table 11 and the 0 part 17.

Therefore, according to such a configuration, since the blade portion 17 is formed to protrude from the plate surface of the punching table 11, the blade portion 17 is formed to protrude from the plate surface of the punching table 11.
Blade t without damaging the board surface of 1! ! 617 can be easily polished. Moreover.

Since the adhesive tape 15 floats up around the blade portion 17, the adhesive tape 15 can be easily peeled off. This eliminates the troublesome work of corroding the plate surface of the punching table 11 as in the past. .

In addition, by arranging the air supply port 18 around the blade part 17, air pressure is evenly transmitted to the entire gap A, and the adhesive tape can be lifted by simply applying a small tension.
5 can be easily removed. Since the adhesive tape 15 can be peeled off with a small tension in this way, the width of the adhesive tape 15 can be made narrower than that of conventional adhesive tapes, which is economical.

Furthermore, by fixing the punch 19 to the sliding plate 21 that is slidably provided on the pair of guides 2020,
Since the axial misalignment of the punch 19 can be suppressed to a small extent, the accuracy of the fitting dimension between the punch 19 and the die 16 can be improved.

This has the advantage that the sharpness of the blade portion 17 can be improved.

As described above, according to this invention, a die-shaped blade for punching out adhesive tape is formed to protrude from the punching table, and the punch is inserted into the die to face the blade and punch out the adhesive tape. By providing this, it is possible to provide a tape processing device that can easily polish the blade portion.

This idea is not limited to the above-mentioned real powers,
Various modifications can be made without changing the gist.
