Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a take-up bobbin side protector for protecting an end surface of a take-up bobbin obtained by winding a film such as a transfer film on a bobbin.

[Conventional technology]

Recently, various types of printers have been used, and thermal transfer printers have been widely used. The transfer film used in this thermal transfer printer is usually supplied in the form of a winding bobbin wound on a bobbin made of paper, plastic or the like.

[Problems to be solved by the device]

However, since the transfer film is an extremely thin film, the end surface of the film of the take-up bobbin is easily damaged during the transfer of the take-up bobbin from the production factory to the consumer. To prevent this, package the take-up bobbin. It was necessary to perform it carefully and be careful not to give vibration or shock during transportation.

The present invention has been made in view of such circumstances, and an object thereof is to provide a take-up bobbin side protector capable of protecting the end surface of the take-up bobbin with a relatively simple structure.

[Means for Solving the Problems]

The take-up bobbin side protector of the present invention has a fitting portion to be inserted into the bobbin for winding the film, a spacer portion formed around the fitting portion and pressed against the end surface of the bobbin, and the film end surface not in contact with each other. It is characterized in that it has a disk portion covered with and a ring-shaped projection provided on the outer periphery of the disk portion and protecting the edge of the film end face.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments of the drawings. FIG. 1 is a perspective view of a side protector according to an embodiment of the present invention, and FIG. 2 is a schematic sectional view showing a state in which the side protector is attached to a winding bobbin. In the figure, 1 indicates the entire winding bobbin. This take-up bobbin 1 has a film 3 on a bobbin 2 made of paper tube, plastic tube, or the like.
It is a wound up. Reference numeral 4 denotes a side protector for attaching to the end surface of the winding bobbin 1, a fitting portion 5 for inserting and fixing the winding bobbin 2 in the bobbin 2, and the fitting portion 5 thereof.
A spacer portion 6 formed around the end of the bobbin 2 for pressing against the end surface of the bobbin 2, a disk portion 7 that extends around the end surface of the film 3 and covers the end surface of the film 3 without contact, and is provided on the outer periphery of the disk portion 7. , And an annular projection 8 for protecting the edge 3a of the film. The side protector 4 is usually made by molding plastic.

The side protector 4 having the above structure is attached to the end surface of the bobbin 2 by inserting the fitting portion 5 into the end portion of the bobbin 2 and pushing the spacer portion 6 until the end surface of the bobbin 2 is pressed, and is stored, Transported, etc. If necessary, after the side protector is attached, the winding bobbin and the side protector may be entirely wrapped in a film or the like. Here, in the state where the side protector 4 is attached, as shown in FIG. 2, the spacer portion 6 is pressed against the end surface of the bobbin, so that even if an external force is applied to the side protector 4 during transportation, the end surface of the film is not contacted with the film. The disk portion 7 does not come into contact with each other, and the film end surface and the edge 3a are well protected. When using the take-up bobbin, the side protector 4 can be removed from the bobbin by simply pulling out the fitting portion 5 of the side protector 4 from the bobbin.

[Effect of device]

As described above, the side protector of the present invention can protect the take-up bobbin end face, particularly the film end face without contact by simply attaching it to the take-up bobbin end face. It is possible to prevent damage to the end face of the film in the middle or the like. Further, since the side protector can be attached and detached by simply attaching and detaching the fitting portion to and from the bobbin, there is an effect that the work is easy.
