BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape attaching device for attaching a tape to a work having a curved tape attaching surface.

[0002]

For example, in a mechanical device such as a robot, a protective tape having an adhesive property on one side is attached to a surface of a mechanical part (work) where wiring may be rubbed. The protection of the wiring has been attempted. In this case, the operation of applying the tape was generally performed manually by an operator.

However, as shown in FIG. 7, when a tape is applied to a concave curved surface such as an inner peripheral surface 1a of a work 1 having a semi-cylindrical shape, wrinkles and air pockets are generated. There was a situation where it was easy and it was difficult to stick the tape neatly. If wrinkles or air pockets occur on the tape, the tape is likely to peel off, resulting in a reduction in quality. For this reason, when the tape is manually pasted by the operator as in the past, it takes a long time for the tape to be pasted, and the quality varies due to the proficiency of the worker, and the tape material is wasted. There were many problems.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tape sticking apparatus capable of easily and reliably performing a sticking operation even when a tape is stuck to a curved surface of a work. It is in.

A work-fixing table for attaching tape, where the work is fixedly set with the tape application surface open, and a long tape set near the work-fixing table that can be pulled out. The tape is rolled along the tape application surface while holding the tape between the tape supply unit and the tape application surface of the work while sandwiching the tape, so that the tape is pulled out from the tape supply unit and attached to the tape application surface. The present invention is characterized in that it has an affixing roller.

According to this method, the work is set on the work fixing table, and the tape is attached to the tape supply unit while the tape is being applied to the tape supply surface while a long tape is set in the tape supply unit. By rolling along the surface, the tape is attached to the tape application surface while being pulled out from the tape supply unit. In this case, the sticking operation is performed only by the worker setting the work or the tape and rolling the sticking roller. In addition, since the application roller rolls while pressing against the tape application surface while sandwiching the tape, the tape can be applied without causing wrinkles or air pockets on the tape.

Therefore, according to the tape sticking apparatus of the first aspect of the present invention, even when the tape is stuck to the curved tape sticking surface of the work, it can be performed in a short time regardless of the skill of the operator. This provides an excellent practical effect that the sticking operation can be easily performed, and the high-quality sticking operation can always be performed reliably without generating wrinkles or air pockets on the tape.

At this time, the work fixing base is provided so as to be movable between a set position where the work is retracted from the sticking roller and the work is attached and detached, and a sticking work position where the tape sticking work is performed by the sticking roller. (Invention of claim 2). According to this, at the set position,
The work of setting the work on the work fixing table can be performed without the sticking roller being in the way.

In this case, it is possible to manually move the work fixing table between the set position and the work position. However, the work fixing table can be moved back and forth between the set position and the work position. A mechanism may be provided (the invention of claim 3). According to this, the movement of the work fixing table can be automated, and more efficient work can be performed.

Further, it is possible to manually rotate the sticking roller, but it is more effective if the sticking roller is driven by a driving source such as a motor. ). According to this, the operation of rolling the application roller along the tape application surface can be automated, and more efficient operation can be performed.
