Abstract

A lead wire pull-out apparatus includes: a lead reel configured to have a lead wire wound thereon; two fixed lead bearings fixed at predetermined positions, on which the lead wire pulled out from the lead reel is slidable; a movable lead bearing arranged between the two fixed lead bearings, the movable lead bearing being movable in a vertical direction and configured such that a lower portion thereof is able to be in contact with the lead wire; and a press-down part configured to press down the movable lead bearing.

Claims

1. A lead wire pull-out apparatus comprising:

a lead reel configured to have a lead wire wound thereon;

two fixed lead bearings fixed at predetermined positions, on which said lead wire pulled out from said lead reel is slidable;

a movable lead bearing arranged between said two fixed lead bearings, said movable lead bearing being movable in a vertical direction and configured such that a lower portion thereof is able to be in contact with said lead wire; and

a press-down part configured to contact and press down said movable lead bearing,

wherein said press-down part presses down said movable lead bearing by a predetermined pressing-down force to thereby pull out said lead wire from said lead reel, and then removes said pressing-down force after said lead wire is pulled out,

wherein after said pressing-down force is removed, the press-down part is separated from the movable lead bearing so as to be out of contact with the movable lead bearing, and

after the press-down part is separated from the movable lead bearing, said lead pull-out apparatus pulls the lead wire from a side where said lead reel does not exist.

2. The lead wire pull-out apparatus according to claim 1, wherein

the size of said movable lead bearing is smaller than the size of said lead reel.

3. The lead wire pull-out apparatus according to claim 1, wherein

the weight of said movable lead bearing is smaller than the weight of said lead reel.
