Description

BOBIN FOR WINDING AND DRAWING which is able to wind up and take out of wide tape material

The present invention relates to a bobbin capable of winding and withdrawing a wide tape-like material, and more particularly, by having a winding wing that can be expanded and contracted radially, after winding a wide tape-shaped material without branching, The present invention relates to a bobbin capable of winding and withdrawing a wide tape-like material that can easily draw out a tape-like material, thereby reducing waste of manpower and resources due to the use of a paper tube, and increasing work efficiency.

In general, in order to wind up a material such as a film, tape, vinyl, or paper in the form of tape, a circular paper pipe, which is an auxiliary device, is inserted and chucked into a chucking device that uses air pressure or a spring, and winds the material on the outer peripheral surface of the paper pipe. The material was taken out together with the branch pipe.

As described above, in order to wind up the material, a branch pipe is necessarily required, and thus, the cost of purchasing the branch pipe is additionally generated, and also, since the branch pipe must be mounted on the chucking device, the work is cumbersome.

In addition, the use of air pressure as the movement source of the chucking device, the air tube method using the air pressure has a problem that the efficiency of the work is reduced because the air pressure decreases over time to check the air pressure during the operation.

In order to improve this problem, as disclosed in the present application "Korean Utility Model Registration Application No. 2006-0008401", after reeling the tape-like material without a support, a reel (REEL) capable of extracting the wound tape-like material was developed. .

The reel disclosed in the aforementioned "Korean Utility Model Registration Application No. 2006-0008401" includes a winding body, a drive rotating shaft disposed horizontally inside the winding body, a first slide cam mounted on the drive rotating shaft, and a second slide. It consists of a drive unit having a cam, and one or more wings that are disposed outside the outer circumferential surface of the take-up body and extend or contract outside the outer surface of the take-up body along the first slide cam and the second slide cam.

By the way, the reel disclosed in the "Korean Utility Model Registration Application No. 2006-0008401" described above, the first slide cam and the second slide cam is screwed to the drive rotary shaft and sliding, the operator can rotate the drive rotary shaft in the drive rotary shaft Since the rotating disk must be provided so that the structure is complicated, it is not easy to manufacture and assemble, and there is a hassle for the operator to manually rotate the rotating disk.

In addition, since the first slide cam and the second slide cam is screwed to the drive rotary shaft, there was a problem that the first slide cam and the second slide cam slips on the drive rotary shaft during the winding operation. This problem has a problem that the material is not wound smoothly because the position of the winding wing is changed during the winding operation.

The present invention was devised to solve the above-mentioned conventional problems, and an object of the present invention is to include a winding wing that can be extended and contracted radially, thereby winding a wide tape-like material without branching, and then wound the tape. It is possible to easily withdraw the upper material to reduce the waste of manpower and resources due to the use of the paper pipe, and to provide a bobbin capable of winding and withdrawing a wide tape-like material that can increase the work efficiency.
