Description

The present invention relates to an adhesive tape holder that securely holds ring-shaped adhesive tapes having different inner diameters and can be easily replaced.

A conventional adhesive tape holder is provided with a cutter on one side of a holder main body provided with a detachable rotor for fitting a ring-shaped adhesive tape. Therefore, the conventional holder described above can be used only for one type of adhesive tape that can be fitted to the rotor.

In addition, there is a holder that urges the opposing left and right cones to approach each other by a spring, and inserts and holds a ring-shaped tape from above in the interval between the cones, or pulls it up to remove it. .
Japanese Utility Model Publication No.57-11976.

However, since there are a plurality of types of adhesive tapes, and the inner diameter of the adhesive tape varies depending on the type, the conventional holder cannot be used for a plurality of types of tapes.
Moreover, if the fitting between the adhesive tape and the rotor is not strong, there is a problem that the adhesive tape and the rotor come off during use.

Moreover, if the fit between the adhesive tape and the rotor is too strong, it takes time to replace the adhesive tape.

In addition, the ring-shaped adhesive tape is inserted from the top against the urging force of the cone and pulled out to remove it. Sometimes it cannot be retained. Further, since the adhesive tape is only held in a point contact manner with the cone on the inside and two rollers on the outside, the holding tape is extremely weak and may come off from the holder during use.

The problem to be solved is that ring-shaped adhesive tapes with different inner diameters cannot be reliably held or easily replaced.

The most important feature is that two fixed rollers and one moving roller are arranged at the vertices of an isosceles triangle.

Since the inner side of the adhesive tape holder of the present invention is elastically held by the three rollers located at the apexes of the isosceles triangle, it is extremely strong and does not come off or come out of the holder during use. Moreover, it is extremely easy to exchange adhesive tapes with different inner diameters, and processing can be performed in a short time.

As described above, the present invention has devised an epoch-making structure with high practical value that can hold adhesive tapes with different inner diameters firmly and easily replace the adhesive tape as described above.

The support piece 6 has an L-shape in which a vertical portion 8 is erected on the tip of a horizontal portion 7 extending from the end leg 4, and an upper fixing roller 9 is provided at an upper end portion on the inner surface of the vertical portion 8. The lower fixed roller 10 is pivotally attached to the lower end portion in a straight line along the vertical direction.

As shown in FIG. 3, an example of a specific configuration of the upper fixed roller 9 or the lower fixed roller 10 is provided with a shaft cylinder 11 protruding above and below the inner surface of the vertical portion 8, and the fixed roller 9 is provided on the upper shaft cylinder 11. The fixed roller 10 is rotatably fitted in the upper shaft cylinder 11, and the stopper 13 is firmly fitted at the tip of each shaft cylinder 11 to support the fixed rollers 9 and 10.

The fixed roller 9 or the fixed roller 10 has the same outer diameter and length, and an engagement groove 12 is formed in the center portion of the outer peripheral surface.

On the other hand, the other end leg 5 erected on the other end of the pedestal portion 2 is inclined toward the central upper portion of the pedestal portion 2, and one end of the other end leg 5 is located on one end side. A flat cylindrical support cylinder 16 is extended and connected.

The support cylinder 16 has a horizontal portion 18 connected to the tip of the inclined portion 17, and a moving roller 26 is movably provided at the tip of the horizontal portion 18.

A specific configuration for supporting the moving roller 26 is as shown in FIGS.

That is, the long hole 19 is opened along the length direction at the front end portion of the inner wall 18a of the horizontal portion 18, and the guide strip 20 is formed along the length direction at the upper and lower portions of the inner surface of the outer wall 18b. Furthermore, ribs 21 are provided along the width direction at the upper and lower portions in the horizontal portion 18.

And in the horizontal part 18, the plate-shaped slider 22 which can slide along a length direction is arrange | positioned. The outer surface of the slider 22 is provided with a guide groove 24 that engages with the guide strip 20 described above, and a shaft cylinder that is loosely fitted into the long hole 19 and passes through the front end of the inner surface of the slider 22. 23, and a locking pin 25 is provided at the rear end of the inner surface.

Therefore, the slider 22 smoothly and smoothly moves in the length direction in the horizontal portion 18 by the engagement of the guide groove 24 and the guide strip 20, and the upper end surface and the lower end surface abutting against the rib 21 in a stable state. The position where the shaft tube 23 abuts on the rear portion of the long hole 19 is the movement limit. The distal end portion of the spring 29 whose base end portion is held by the holding pin 30 provided inside the end leg 5 is locked to the locking pin 25 of the slider 22. Is energized backward.

A moving roller 26 having a diameter larger than that of the fixed roller 9 or the fixed roller 10 is rotatably fitted in the shaft cylinder 23 of the slider 22 that protrudes through the long hole 19, and a stopper is provided at the tip of the shaft cylinder 23. 28 is firmly inserted to support the moving roller 26, and an engaging groove 27 is provided around the center of the outer peripheral surface of the moving roller 26.

The above-described fixed rollers 9 and 10 are vertically connected, and the straight line connecting them is the vertical direction. The horizontal portion 18 of the support tube 16 is horizontal. The two fixed rollers 9 and 10 and the moving roller 26 are positioned at the vertices of the isosceles triangle, and the movement miracle of the moving roller 26 is relative to the straight line connecting the two fixed rollers 9 and 10. Are perpendicular to each other. Moreover, even if the moving roller 26 moves, the isosceles triangle with the two fixed rollers does not collapse, and the slider 22 is urged rearward by the spring 29, so that the moving roller 26 is always the two fixed rollers 9. 10 is biased in a direction away from 10.

A cutter leg 14 is erected from the lower end of the end leg 5 toward the upper outer side, and a cutter piece 15 is provided at the upper end of the cutter leg 14.

In the drawing, reference numeral 31 denotes a ring-shaped holding body having an engagement strip 32 provided at the center of the inner peripheral surface and a plurality of ribs 33 provided at equal intervals along the width direction on the outer peripheral surface.

A ring-shaped adhesive tape 34 is fitted and held on the outer periphery of the holding body 31, and the holding is ensured by the rib 33, and each of the rollers 9, 10 and 26 described above holds the holding body 31. Since it is inscribed in the body 31, the holding body 31 is supported rotatably.

Accordingly, the inner diameter of the holding body 31 is substantially equal to the diameter of a virtual circle formed by the outer edges of the rollers 9, 10, 26.

In order to support the holding body 31 on each of the rollers 9, 10, 26, the moving roller 26 may be moved in the direction close to the fixed rollers 9, 10 against the bias of the spring 29. The diameter of the hypothesized circle becomes smaller and the holding body 31 can be easily fitted, and the moving amount of the moving roller 26 may be adjusted in accordance with the inner diameter of the holding body 31.

When the holding body 31 is fitted, the engaging grooves 32 and 27 of the rollers 9, 10 and 26 are engaged with the engaging strips 32 of the holding body 31, whereby the holding body 31 by the rollers 9, 10 and 26 is engaged. Retention is ensured.

Further, after the holding body 31 is fitted, when the moving roller 26 is moved by the bias of the spring 29, each of the rollers 9, 10, 26 elastically contacts the inner peripheral surface of the holding body 31, Secure holding is ensured and maintained.

In use, the adhesive tape 34 is pulled out from the end portion, but the rollers 9, 10, and 26 are rotatable around the shaft cylinders 11 and 23. Therefore, the holding body 31 also rotates smoothly, and the drawer Can be easily performed, and can be cut by the cutter piece 15 of the cutter leg 14 by a predetermined amount.

Although the moving roller 26 has a large diameter, if the diameter corresponds to the inner diameter of the small adhesive tape 35, the moving roller 26 can hold the small adhesive tape 35.
