As can be seen in FIG. 3A, each pair of guide members 332a (not shown in FIG. 3A) of the plurality of forward and backward devices 330a, 330b, 330c is fixed to one support member 332b. Is mounted. Both sides of the fork member 320 are fixedly mounted to the pair of first and second pulleys 334a and 334b by a pair of first fixing members 335a and a pair of second fixing members 335b, respectively. do.

On the other hand, the first groove 321 is formed in the rear portion of the fork member 320. The first groove 321 is formed in a direction perpendicular to the moving direction of the fork member 320. In addition, the support member 332b is provided with a pair of second grooves 323 in a direction parallel to the first grooves 321. The pair of front link portions 340a of the collapsible link bar 340 are coupled to be movable along the first groove 321, and the pair of rear link portions 340b of the link bar 340 are paired. Is coupled to be movable along the second groove 323 of the. In addition, the pair of rear link portions 340b of the link bar 340 is connected to the pair of return elastic members 342 provided in the pair of second grooves 323. The pair of return elastic members 342 may each be embodied as a spring, for example.

In addition, the cam follower 345 is connected to the rear cross linking portion 340c of the link bar 340 through the connecting member 344, and is in contact with the cam 349 through the roller 348. In this case, the support member 332b may further include a guide bush 346 at a central portion of the support member 344b to prevent bending during the forward and backward movement of the connecting member 344. The use of such guide bush 346 is not necessarily required as an optional feature.

3E is a plan view illustrating a connection relationship between a shaft, a plurality of cams, and a plurality of rollers used in a plurality of forward and backward devices according to an embodiment of the present invention.

Referring to FIG. 3E, in one embodiment of the present invention, a plurality of cams 349a, 349b, and 349c used in the plurality of forward and backward devices 330a, 330b, and 330c maintain one constant angle θ, respectively. It is fixedly mounted to the shaft 350. Here, the constant angle θ allows the forward and backward movements of the plurality of fork members 320a, 320b, and 320c to be sequentially performed as the cams 349a, 349b, and 349c rotate. That is, by varying the constant angle θ between the plurality of cams 349a, 349b, and 349c, it is possible to vary a constant time difference in which the forward and backward operations of the plurality of fork members 320a, 320b, and 320c sequentially occur. Therefore, by increasing or decreasing the constant angle θ between the plurality of cams 349a, 349b, and 349c, the time difference between the fork members 320a, 320b, and 320c in which the forward and backward operations sequentially occur may be increased or decreased. Can be.

Referring again to FIGS. 3A-3E, in the forward and backward apparatus 330 according to the embodiment of the present invention as described above, when the driving member 360 (see FIG. 3A) drives the shaft 350 to rotate, A plurality of cams 349a, 349b and 349c fixedly mounted to the shaft 350 at a constant angle θ rotate at the same time. When the first cam 349a of the plurality of cams 349a, 349b, and 349c is in the position as shown in Fig. 3B, the first fork member 320a is in the reverse position. Thereafter, when the first cam 349a is rotated to the position as shown in FIG. 3C by the rotation of the shaft 350, the first roller 348a moves along the surface of the first cam 349a to the shaft 350. Move away from Accordingly, the first link bar 340 connected to the first roller 348a is extended through the first connecting member 344a, and the first link bar 340 is connected to the pair of front link portions 340a of the first link bar 340. The first fork member 320a is moved to the forward position along the pair of first guide members 332a by the pair of first and second pulleys 334a and 334b.

Thereafter, when the first cam 349a is rotated to the position as shown in FIG. 3B again by the rotation of the shaft 350, the first cam in the pair of second grooves 323 of the support member 332b. The first link bar 340 is reduced by the pair of return elastic members 342 connected to the pair of rear link portions 340b of the link bar 340. As a result, the first fork member 320a connected to the pair of front link portions 340a of the first link bar 340 is connected to the pair of first and second pulleys 334a and 334b. 1 moves along the guide member 332a to the reverse position as shown in FIG. 3B.

Specifically, the forward and backward motions of the second and third fork members 320b and 320c may be rotated between the first cam 349a and the second cam 349b (2θ in FIG. 3E) and the second cam 349b. Each of the third cams 349c has a time difference corresponding to the rotation angle (θ in FIG. 3E).

In the above-described manner, the electrode supply device 300 according to an embodiment of the present invention sequentially sequentially the plurality of fork members 320a, 320b, and 320c by a plurality of forward and backward devices 330a, 330b, and 330c. It is possible to supply with. In addition, when the electrode supply device 300 according to an embodiment of the present invention is used as the first electrode supply device 214 and the second electrode supply device 224 shown in FIGS. 2B and 2C, respectively, It is possible to advance and retract the first fork members 216a, 216b, 216c and the plurality of second fork members 226a, 226b, 226c in a sequential and alternating manner.

Meanwhile, in the forward and backward apparatus 330 shown in FIGS. 3B and 3C, a solid bar may be used instead of the collapsible link bar 340. However, the rigid bar can advance or retract the fork member 320 only by the stroke resulting from the rotation of the cam 349, while the link bar 340 is shown in the cross link portion as shown in 3b and 3c. The fork member 320 can be moved forward or backward by a distance much larger than the stroke resulting from the rotation of the cam 349 in proportion to the number.

In this case, the roller 348 of the cam follower 345 is mounted in the guide recess 352 so that the cam member 349d is rotated about the shaft 350 by the driving member 360 (see FIG. 3A). The fork member 320 (see FIGS. 3B and 3C) may be moved forward or backward by moving in the horizontal direction along the guide recess 352. That is, since the roller 348 is constrained in the guide recess 352, the link bar 340 can be expanded and contracted by the rotation of the cam member 349d. Thus, the use of a pair of returning elastic members 342 as shown in FIG. 3A where link bar 340 is provided to move from the forward position to the reverse position is unnecessary.
