Note that the rail C is fixedly installed on fixing bases E and F in a horizontal state across the front and rear positions of the welding machine.

The wire tray device A is composed of a tray portion 1 and a lid portion 11 (FIG. 2). As shown in FIGS. 2 and 3, the saucer portion 1 includes a tooth-shaped frame 2 having a plurality of V-shaped recessed grooves 2a formed in the upper part thereof in a direction perpendicular to the longitudinal direction. 3
They are arranged parallel to each other and spaced apart from each other. Note that 2b is a protrusion, and the circumscribed width between each tooth frame 2 and the floor wall board 3 is configured to be shorter than the width of the target wire frame X, that is, the length of the wire rod Y. Further, on the saucer part 1, there is provided an abutment 4 supported on the floor wall board 3 at a position between each of the toothed frames 2 via support springs 5 as elastic bodies. Each spring 5 has a core shaft 6 penetratingly disposed vertically above the floor wall board 3, thereby limiting the movement of the support 4 only in the vertical direction. Further, the support spring 5 is set so that the surface of the support base 4 is between the valley position of the concave groove portion 2a and the top position of the protrusion portion 2b. Further, a locking device 7 with a locking ring 7a is provided at the center on one side wall surface of the saucer portion 1. As shown in FIGS. 2 and 4, the lid portion 11 has
It is connected via a hinge 10 on the other side wall surface of the saucer part 1, and the upper surface of the saucer part 1 is opened and closed via this hinge 10. In addition, two fixing devices 12 are provided on the front and rear side walls 11b and llb surface of the lid portion 11, respectively, and the corresponding concave grooves 2 of each tooth frame 2 are provided.
a... are arranged corresponding to the positions to be pressed when closing the lid with respect to the wire frame X placed on the saucer portion 1. As shown in FIG. 5, this fixing device 12 is disposed on the lid part 11 via a fixing box 20, and a fixing claw is attached to the lower end of the fixing box 20 through a support plate 24 to a perforation on the lower surface of the fixing box 20. A core shaft portion 22 having a diameter 21 is disposed in an inserted manner, and a locking head 23 is formed at the upper end of the core shaft portion 22 . Further, a spring 25 is provided in a wound manner on the portion of the core shaft portion 22 that is exposed to the outside. Also, the fixed claw 21
is formed to have a beveled edge 21&, and is arranged in the lid portion 11 so that the normal line to this beveled edge 21& faces outward. As a result, when the fixing claw 21 is pressed from above to the wire frame An acting force is generated on the fixed claw 21 based on the elasticity of the fixed claw 21, and the contact position of the oblique edge 21M with respect to the wire frame X is shifted upward. As a result, the wire frame X is fixed onto the tray portion 1 in an extremely stable manner. Further, in the lid part 11, an insulating elastic body 14 is provided on the upper surface of the earthen wall part 11a and a long presser member 13.13 is vertically provided on the lower surface of the earthen wall part 11a along the side wall 11b. As shown in FIG. 6, the vertical height of each holding member 13 is determined by indirectly compressing the support springs 5 when the lid portion 11 is closed, and using the resulting elasticity to fix each wire frame Y. It has a size that allows it to be clamped and pressed onto the support base 4 at a position spaced apart from the shaped wire frame X.

In this clamped and pressed state, each wire rod frame Y can be displaced along the surface of the support base 4 by the action of an external force.

Further, a locking protrusion 15 is provided on the side wall surface of the lid part 11,

At this time, the guides 27 and 28 are arranged along the respective exceptional positions of the tooth profile frames 2 and 2 to facilitate aligning their respective ends during the mounting operation of each wire frame Y. can.

Next, when the lid part 11 is closed, the fixing claws 21 of each fixing device 12 come into contact with the bent part of the wire frame X, and as described above, the wire frame X is firmly fixed on the saucer part 1. At the same time, each holding member 13 clamps and fixes each wire rod frame Y onto the support base 4. In this case, both ends of the wire frame X portion and each wire frame Y protrude from the outer surface of the toothed frame 2 of the saucer portion 1, respectively.

This wire rod tray device A is supported on a moving device B via a support 16 by support springs 17 each having a core shaft 18 (FIG. 2).

Next, when the movable conductive support rod 35 moves downward and the conductive part 34 moves downward, the protruding part 36 comes into contact with the upper surface of the insulating elastic body 14, and then as shown in FIG. The entire wire tray device A is pushed down against the elasticity of the insulating elastic body 14 and the support spring 17, and the wire frame X portion is pressed against the electrode shoulders 31a, 31a. Furthermore, when the conductive part 34 is moved downward, each electrode chip 33 presses down the vicinity of the end of each wire rod Y against the elasticity of the support spring 7, and each wire rod frame Y is pushed down. The wire rods are pressed onto the wire rod frame X near their ends, and at the same time as this pressing, the abutting portions of each wire rod are electrically welded.
