Title:
WIRE TRANSPORT DEVICE AND WIRE TRANSPORT METHOD
Document Type and Number:
Japanese Patent JP2022032082
Kind Code:
A
Abstract:
To prevent tension applied to a wire from varying and partially equalize tension applied to a wire pulled by a plurality of pulleys.SOLUTION: A wire transport device 10 comprises a wire supply portion that delivers a wire 11, a wire recovery portion that recovers the delivered wire 11, and a plurality of pulleys 51 which pull the wire 11 between the wire supply portion and the wire recovery portion. One or two or more of pulleys 51 are formed of conductive nonmagnetic materials, and permanent magnets 54 are provided to be coaxially rotatable opposing to the pulleys 51 formed of conductive nonmagnetic materials, and rotating means 56 and 57 that rotate the permanent magnets 54 are provided. All of the plurality of pulleys 51 are formed of conductive nonmagnetic materials, and the plurality of pulleys 51 are arranged so that the wire 11 are alternately stretched around the pulleys. it is preferable that the rotating means have a motor 56 for an odd number that makes the pulleys 51 on the odd number rotate the corresponding permanent magnets 54 and a motor 57 for an even number that makes the pulleys 51 on the even number rotate the corresponding permanent magnets 54.SELECTED DRAWING: Figure 1
