Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end processing device for cutting a front end and a rear end of a coiled wire.

Conventionally, the end treatment of a coiled wire has been carried out while the conveyance is stopped during the conveyance route. Therefore, there was a problem in that the overall work efficiency was lowered due to this stop work.

An object of the present invention is to provide an end processing device that can process the ends of a coiled wire online.

In order to achieve the above object, the end processing device for coiled wire according to the present invention includes a first traveling carriage which is disposed straddling a conveyor device that conveys the coiled wire in an unfolded state, and an upper part of the first traveling carriage. A second traveling trolley is disposed at and configured to be able to reciprocate independently in the conveying direction of the conveyor device, and the second traveling trolley detects the front end and the rear end of the coiled wire rod. a detection device for
A movable platform capable of reciprocating in the conveyance direction, an elevating frame attached to the movable platform, and a cutting device and a holding device provided at the lower end of the elevating frame are provided, and the first traveling cart is provided with the holding device. A cradle is provided for receiving the cutting terminal passed from the cradle, and a removing device for removing the cutting terminal on the cradle is provided at the end of the travel path of the first traveling carriage.

According to this configuration, the following effects can be expected. That is, when the detection device detects the rear terminal, the movable platform is moved to correct the position of the cutting device relative to the rear terminal while the second traveling cart is traveling at the same speed as the conveyor device, and the elevator frame is lowered. Accordingly, the cutting device can cut the rear end, and the cutting end can be held by the holding device. Therefore, when the lifting frame is raised and the terminal is lifted after disconnection,
By locating the first traveling carriage below the cutter, the terminal can be transferred to the receiving stand after cutting. Further, when the detection device detects the front terminal, the movable platform is moved to correct the position of the cutting device with respect to the front terminal while the second traveling cart is traveling at the same speed as the conveyor device, and the elevator frame is lowered. Accordingly, the front end can be cut by the cutting device, and the uncut end can be held by the holding device. Therefore, by placing the first traveling cart in a running position below the cutting terminal while the lifting frame is raised,
The cutting front end terminal can be passed to the cradle. By driving the first traveling cart to the end of the traveling route, the cut end and the pre-cut end on the receiving table can be removed by the removal device. That is, according to the present invention, the front end and the rear end of the coiled wire rod being transported in the unfolded state can be cut and separated and removed without stopping the transport, thereby improving the overall work efficiency. be able to. Furthermore, full automation is possible, which ensures reliable and safe cutting at all times.
