Abstract

(57) [Abstract] [Purpose] To provide a bobbin wound with a wire used in a wire cut electric discharge machine or the like that can be treated without pollution when it is not used. [Structure] The cylindrical body and the brim are molded from robust laminated cardboard, and the inner surface of the brim is provided with an arc-shaped scale line indicating the remaining amount of the rewound wire.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bobbin for winding a wire rod such as an electrode wire used in a wire-cut electric discharge machine and rewinding the wire rod by applying it to a machine.

[0002]

[Prior art]

 All conventional bobbins of this type are made of synthetic resin and molded integrally with the body and the receiving part, so they cannot be used due to cracks or chips during use, especially for the treatment of used bobbins. I have a hard time. Discarding it as it was would be pollution, and we had no choice but to pay the fee to a professional company and ask for cleaning up. It is extremely uneconomical.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a bobbin which is advantageous in use and can be treated without any pollution.

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows. A cylindrical body around which any wire is wound, and the receiving ribs attached to both ends of the cylindrical body are molded from robust cardboard, and at least one of the receiving ribs has an arcuate scale line coaxial with the cylindrical body on the inner surface. A bobbin that has been applied to the required place.

[0005]

【Example】

 In the figure, reference numeral 1 is a bobbin cylindrical body portion, and 2 and 3 are receiving members fixed to both ends of the cylindrical body portion 1, both of which are made of thick and thick laminated cardboard, and can be burned for processing after use. I have it. An arc-shaped graduation line 4 concentric with the cylindrical body 1 is provided on the inner surface of at least one of the receiving ribs 2 and 3. In the illustrated embodiment, the receiving holes 2 and 3 are provided with insertion holes 5 around which the tips of the wound wire rods are hooked.

[0006]

【effect】

 According to the present invention, after the wire is used, it can be burnt and disposed of, so that a great effect that it can be treated without pollution unlike the conventional plastic product is exhibited. Moreover, since the inner surface of the receiving collar is provided with an arc-shaped graduation line which is concentric with the cylindrical body, the remaining amount of the unwound wire can be seen at a glance. In particular, the bobbin of the present invention can be manufactured at a low price using recycled paper, and it is a practical device that works together with pollution prevention.
