Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticking device for an adhesive tape, and more particularly, to a device for sticking a wound adhesive tape to an object to be adhered as it is being fed out, and which is easily cut with a deployed cutting blade. The present invention relates to a sticking device that can be used.

[0002]

2. Description of the Related Art Conventionally, when sticking an adhesive tape to an object to be adhered, a tape feeding end of a wound adhesive tape mounted on a stationary type tape holder is gripped with a fingertip and fed out. Cut and paste at the desired length,
Adjustment work was necessary because the length was too short or too long to cut or add. To solve this problem,
Hold the tape holder, move it along the part to be pasted, move out the adhesive tape to the desired length without excess or shortage, and stick it,
Furthermore, a cutting structure has been proposed, which is convenient for consumers as a tape holder mainly used in packing work.However, this type of sticking device has an adhesive surface because the feeding end is always exposed outside the main body. Dust or the like adheres to the surface, or adheres to an unnecessary portion, and a work such as cutting off the front end portion before use occurs.

[0003] In addition, the cutting blade is dangerous because it is exposed at the tip of the tape holder. Further, as a mechanical problem when the feeding tape is adhered while being pressed by the adhering roller, the cutting blade is stuck. Since it is arranged in front of the application roller, the cutting blade at the end of application is already on the application tape that has been applied.Therefore, when cutting, separate the application roller from the adherend and cut while feeding the adhesive tape. The blade is moved to the end of sticking, and the tape holder is further tilted for cutting.However, in this model, the part that has already been stuck is peeled or stuck depending on the type of sticking object and the strength of the adhesive tape. There was a problem that the kimono was lifted and further damaged by the cutting blade.

If the cutting blade is disposed in the case body without exposing the same, the payout tape is naturally cut in the case body, and the next time the sticking operation is performed, the cut tape payout end is attached to the case body. It is necessary to protrude outside so that it can be pinched with a fingertip, or at least to a position where it can be pressed by the sticking roller, but a simple and practical mechanism that solved this problem has not yet been developed, and many The device of the present invention moves the sticking roller upward after sticking is finished, peels off the part that has already been stuck and cuts it, and uses this peeled part as the sticking start end for the next sticking, so there is still the problem of peeling. Has not been resolved, and even if it is commercialized, it has not been recognized by consumers.

[0005]

Accordingly, all the manufacturers have tried to solve this problem with a great deal of time and money and with a complicated structure, but they have not been able to sufficiently solve the problem. The present invention has been invented in order to meet such strong demands of consumers.

[0006]

An opening is provided at the bottom of the case body, a roller A is provided at the front opening end, a shaft is provided at a predetermined position in the case body, and the wound adhesive tape is rotated. A tape holder provided with a freely supporting tape support and a non-adhesive guide roller B is pivotally supported, and the center of the tape support is pivotally supported. Further, the rotation of the tape holder is rotated within a required range. A difference is provided in the distance from the guide roller B to the opening by the rotation of the tape holder, and the spring is normally biased and held at a position where the distance is long, that is, the guide roller B is separated from the opening,

Further, a guide roller C for guiding the feeding tape to the opening is provided above the opening, and a rotary blade for rotating the gap between the guide roller C and the roller A provided at the opening end is provided coaxially with the tape holder. Further, the rotation of the rotary blade is restricted to a range in which the blade advances and retreats toward the opening, and is normally biased and held by a spring at a position retracted from the opening,

An operation section for rotating the tape holder and the rotary blade is provided so as to protrude from the intermittent section formed in the case body, and the rotary blade operation section is operated to cut out the fed tape. By moving the guide roller B by operating the holder operation unit, the distance to the opening is shortened, and the extra feeding tape generated from the distance difference is projected from the opening.

[0009]

In the case of the type in which the case body is directly pressed onto the object to be adhered, by operating the tape holder operating section, the roller A having the tape feeding end provided at the opening end.
, And in this state, the case body is pressed against the object to be adhered, and the case body is slid along the planned sticking portion to perform sticking, and the roller A reaches the scheduled sticking end position. After that, the guide roller B is moved by opening the tape holder operating section, and the tape feeding section in the case main body is additionally fed, and then the cutting blade operating section is operated to perform cutting. In this model, the roller A provided at the open end
Functions as a sticking roller, and since the roller A releases the tape holder operating part while pressing the adherend, the extra tape feeding part is fed from the wound adhesive tape, and peeling does not occur. . Therefore, the release of the tape holder is not limited to after the end of the application, but may be at any time after the roller A presses the tape feeding end against the adherend, that is, after the application start end is formed.

When the case main body cannot be pressed directly against the adherend due to the shape or use of the adherend, the tape feeding end is made to protrude long from the case main body so that it can be pinched by a fingertip. The range is increased and the distance to the opening is increased.When using, hold the case body with one hand, operate the tape holder operation part with your fingertip, and let the tape feeding end protrude from the opening, the other The tape feed end is nipped with one finger of the hand and fed out an appropriate length, and then the tape holder operating section is released to move the guide roller B to the side separated from the opening, that is, necessary at the time of starting the next sticking. After providing an extra tape feeding section, attach the sandwiched tape feeding end to the object to be adhered, then move the case body and feed out the adhesive tape. Performed after sticking ends to cut by operating the operation unit of the rotary blade. In the case of this type, the problem of wrinkles and curling can be solved by releasing the pressure-sensitive adhesive tape from the wound pressure-sensitive adhesive tape and applying the tape after applying the pressure.
