Further, as shown in FIG. 3, the transport roll devices 6 to 8 include a plurality of rolls 23 for pinching the wire rod W0, and all or part of the rolls 23 rotate while the wire rod W0 is pinched. The wire material W0 is conveyed by being driven. The rolls 23 are in a closed state in which the wire W0 is clamped (FIG. 3B) and in an open state in which the clamp is released (FIG. 3B).
It can be opened and closed between (a)).

The operation of the wire rod feeding device 1 will be described below, focusing on the wire passing step. First, as shown in FIG. 4A, after the wire W0 taken out from the upper part of the wire storage part 2 is laid over the upper side of the turn roll 9, the leading end thereof is set on the transport roll device 6. As shown in FIG. 3A, the transport roll device 6 is opened, the wire rod W0 is inserted between the rolls 23, and then the roll 23 is driven in the closed state as shown in FIG. 3B to drive the wire rod W0. Is guided toward the dancer roll device 3 while being guided in the guide member 10. The dancer roll 13 of the dancer roll device 3 waits for the wire W0 to be fed in above the auxiliary rolls 14 and 15 (that is, in a state in which it is located above the transport path of the wire W0).

The wire W0 passes between the dancer roll 13 and the auxiliary rolls 14 and 15 and reaches the downstream transfer roll device 7 while being guided by the guide member 11. As shown in FIG. 4C, the transport roll device 7 stands by in the open state, the wire rod W0 passes between the rolls 23, and shifts to the closed state to transport the wire rod W0 further downstream.
Then, the transport roll device 6 on the upstream side shifts from the closed state to the open state almost at the same time. That is, the upstream and downstream transport roll devices 6 and 7 do not simultaneously close to the wire W0 (that is, a state in which the wire W0 is pinched and transported), and the roll 23 rotates between the two. Eliminates the need to synchronize drives.

When the wire rod W0 is nipped by the transport roll device 7, as shown in FIG. 4 (d), the dancer roll 13
Descends to form a hanging portion Q on the wire W0. A wire rod detection sensor 24 is provided at the outlet of the guide member 11.

In order to prevent a speed difference from occurring, the drive is controlled so as to synchronize with each other.

As described above, the raw material wire W0 passed from the wire storage part 2 to the processing device 5 is bent and deformed in the bending imparting part 17 of the scale removing device 4 while being conveyed in the longitudinal direction. . The scale formed on the surface of the wire W0 is broken by the bending and peels off. Then, the scales, dirt, and the like that have not been removed by bending are removed from the wire brushes 18, 19 in the polishing section 20.
Then, the cleaning liquid is sprayed from the cleaning nozzle 21 in the cleaning unit 22 to clean the surface. The raw material wire W0 from which the scale has been removed in this manner is supplied to the processing device 5 and subjected to predetermined processing.

When the wire rod W0 is prevented from being unwound from the wire rod storage section 2 due to the entanglement of the wire rod W0, there is a difference in the transport speed of the wire rod W0 between the upstream side and the downstream side of the dancer roll device 3. In the case of occurrence of, the dancer roll 13 moves up and down to change the length of the drooping part Q, and the above speed difference is absorbed. On the other hand, when it becomes necessary to cut the wire rod W0 downstream of the scale removing device 4 due to a problem that has occurred in the processing device 5 or the like, the roller 23 is driven while the wire rod W0 is sandwiched by the transport roll device 8. After stopping the feeding, stopping the feeding of the wire W0 and cutting the wire W0, the feeding roll device 8 is driven again to supply and set the wire W0 to the processing device 5, and the work can be performed easily. it can.

In the above wire rod supply system 1,
When it is not necessary to remove the scale from the surface of the raw material wire W0, the scale removing device 4 can be omitted. Accordingly, the transport roll devices 7 and 8 can be omitted as appropriate. Further, the wire rod supply system of the present invention is not limited to the case where the raw wire rod is supplied to the processing device, and the wire rod after wire drawing is sent to the next step such as heat treatment or surface treatment, or subjected to predetermined processing or treatment. To wind the wire,
It can also be used when supplying to a winder.
