Description

[Detailed explanation of the idea] "Purpose of invention" a Industrial application field The present invention relates to an adhesive tape applicator.

b. Prior art A tape cutting tool whose top surface of a metal fitting having a gate-shaped cross section is extended forward and its tip is shaped like a cutter is attached to the adhesive tape so as to straddle it, and the adhesive tape is pressed onto a paper surface etc. with a fingertip. The adhesive tape is applied to the paper surface by applying it while cutting and cutting the end with the cutter. Also, rewind the tape attached to the stand.

c Problems that the invention aims to solve When applying adhesive tape to a paper surface while unwinding it, it is necessary to press the applied surface with a fingertip each time to ensure adhesion. If the adhesive tape is unwound for a long time, the adhesive tape will twist and the adhesive surfaces will adhere to each other, often making it unusable.

"Structure of the invention" a. Means for solving the problem A reel fitted with adhesive tape is rotatably supported at the lower end of the arm, and a rotary sealer is rotatably supported at the lower end of the arm. At the same time, the open end of the portal frame rod is pivotally attached to the lower end of the arm, the cutter is fixed downward to the front of the portal frame rod, and rolls are mounted on both sides to prevent the cutter from scratching the paper surface. furthermore, an operating lever having a fan-shaped gear formed at its lower end is swingably pivoted to the lower end of the arm, and the gear is integrally fixed to the open end of the portal frame rod to mesh with the fan-shaped gear; The above problem was solved by providing a tension roll between the rotary sealer and the reel to prevent the adhesive tape from loosening.

b Function and Examples The function and examples of the present invention will be explained with reference to the drawings. Two arms 1, 1 each made of a band-shaped plate bent in a dogleg shape are held at a distance slightly wider than the width of the adhesive tape 2. The width of the upper end 1a of each arm 1 was slightly reduced, a ridge 1b was provided on the outside, and the adhesive tape 2 was fitted over the upper end 1a, slightly closer to the center than the upper end 1a. The reel 3 is rotatably supported. A rotating sealer 4 having a width slightly wider than the width of the adhesive tape 2 is rotatably supported between the lower ends of the arms 1, 1, and its pivot 4a is connected to the arms 1, 1.
The open end of the gate-shaped frame rod 5 is pivoted to the pivot shafts 4a, 4a so as to be able to swing vertically,
A cutter 6 whose cutting edge is gently concave toward the center is fixed so as to slightly protrude from the lower front end of the portal frame rod 5, and a pair of cutters 6 are attached to the front outside of the portal frame rod 5 to prevent scratching of the paper surface. Rolls 7, 7 are mounted on shafts, and the radius of the rolls 7 is formed to be larger than the length of the cutting edge of the cutter 6. The center 8a of the sector gear 8 is pivotally connected to the lower end of the arm 1, and a pressing spring 9 is elastically supported between the arm 1 and an end of an operating lever 8b extending in the opposite direction of the sector gear 8 with respect to the center 8a. A gear 10 that meshes with the sector gear 8 is integrally fixed to one open end of the portal frame rod 5, and the portal frame rod 5 is swung up and down by the vertical movement of the operating lever 8b. A roll 7 and a cutter 6 integral with the frame rod 5 are swung up and down. In order to prevent the adhesive tape 2 from loosening, a tension roll 11 is installed horizontally and rotatably between the tips of the arms 1 and 1 near the rotary sealer 4. As shown in FIGS. 4 and 5, the adhesive tape applicator according to the present invention is constructed by bending a channel material in an ∠ shape with its opening facing upward, and attaching each land provided on arm 1 to the upper end of the bent portion. A stand 1 provided with a groove 12a into which the strip 1a is fitted and a stepped portion 12b into which each upper end portion 1a of the arm 1 is fitted.
2, turn the arm 1 upside down, and fit the upper end 1a into the step 12b and the ridge 1b into the groove 12a.
It is then used by cutting it to a desired length using the unwinding cutter 6.

``Effect of the invention'' Since the invention is constructed in this manner, the adhesive tape 2 is set so as to project slightly forward of the rotary sealer 4, and the adhesive tape 2 is pasted to the desired length while pressing the rotary sealer 4 onto the paper surface. After applying the cloth, when the operating lever 8b is pushed down against the elastic force of the pressing spring 9, the gear 10 that meshes with the fan-shaped gear 8 rotates.
The gate-shaped frame rod 5 integrated with the paper moves downward and the cutter 6 cuts the adhesive tape 2, and the adhesive tape 2 is twisted by the simple task of applying the tip of the adhesive tape 2 to the paper surface with a fingertip. It can be easily applied without causing unnecessary adhesion of adhesive surfaces. When the finger pressing the operating lever 8b is released, it returns to its original position, rotates the gear 10, moves the gate-shaped frame rod 5 upward, and the cutter 6 leaves the surface of the paper and waits for the next cutting operation. Adhere the tip of the adhesive tape 2 to the surface to be adhered, move the arm 1 toward you or to the side, release the rotary sealer 4 from the surface slightly before the position to be adhered, and continue moving the arm 1 in the same direction. Then, the operating lever 8b is pressed to move the cutter 6 downward to cut the adhesive tape 2 that is away from the surface to be adhered, and after cutting, the separated part is pressed with fingers to ensure adhesion. When the adhesive tape 2 is pressed and applied by a rotary sealer 4, a roll 7 rotates in contact with the paper surface and the cutting edge of the cutter 6 is prevented from scratching the paper surface, so that the paper surface is not damaged. Furthermore, when the product of the present invention is attached to the stand 12, the adhesive tape 2 can be rewound and cut into appropriate lengths for use, without having to cut the adhesive tape 2 and carry it to the place to be applied. It has the advantage of being easy to carry and apply.

As described above, the present invention has a simple and robust structure, is easy to manufacture, is inexpensive, and has high practical value.
