Description

  The present invention relates to a coil carry-out device, and more specifically, a coil winding machine winds the other end of a long rectangular wire having a rectangular tube-shaped first coil wound at one end in the length direction. When forming the square coil-shaped second coil portion by wire processing, the coil winding machine assists the completion of the second coil portion while holding the first coil portion, and the completed connection coil is carried out. The present invention relates to a coil carry-out device.

2. Description of the Related Art Conventionally, a wire rod processing apparatus is known in which a wire rod sent from a wire rod supply apparatus is processed with a plurality of processing machines, and then the processed wire rod is unloaded with a wire rod unloading apparatus (see, for example, Patent Document 1).
In the wire rod processing apparatus disclosed in Patent Document 1, a wire rod having hooks formed at both ends is processed, and a hook is bent by a processing machine to process a subtie. And it is the structure which carries out the processed subtie with a wire material carrying-out apparatus, and accommodates in a product accumulation | storage part.

By the way, as another conventional example, after forming a rectangular tube-shaped first coil portion at one end portion of a rectangular wire as a long material, for example, a rectangular tube-shaped second coil portion is formed at the other end portion of the rectangular wire. And the connection coil formation apparatus which forms so that both coils may become parallel is known.
In this connection coil forming apparatus, first, in order to form the first coil portion, the rectangular wires are sequentially sent out and wound by the coil winding machine for forming the first coil portion, and then the first coil is formed at one end portion. A rectangular wire having a portion is sequentially sent out from the other end portion and wound by a coil winding machine for forming the second coil portion.

When the second coil portion is wound on the other end of the flat wire, for example, a fixing jig and a winding jig of a coil winding machine are used.
That is, after sandwiching the flat wire sent between the fixing jig and the winding jig, the winding jig is first rotated by 90 degrees to wind, and then the winding jig is returned to the original position. At the same time, the rectangular wire is fed by one side and the winding jig is rotated 90 degrees again to repeat the winding process until the predetermined number of steps is reached, thereby forming the first and second coil portions having a rectangular tube shape. .

  In the above case, when forming the second coil part, the other end part of the rectangular wire having the first coil part at one end part is sequentially fed, but the other end part is gripped by the coil winding machine and can be wound. In such a state, there is a sufficient distance between the first coil portion and the coil winding machine to form the second coil portion.

In order to send out the rectangular wire sequentially from the other end, for example, it is conceivable to use a rectangular wire sending machine that sandwiches the rectangular wire with a pair of pulleys rotating in opposite directions and sends out the rectangular wire. As the second coil portion is wound, the feeder interferes with the first coil portion that approaches the second coil portion, and thus needs to be retracted from the first coil portion and the rectangular wire. When the flat wire sending machine is retracted from the flat wire or the like, the flat wire cannot be sent out, so another feed mechanism is required instead.
In this case, since the first coil portion is provided at one end of the flat wire, the flat wire cannot be sandwiched between the pair of pulleys as described above, and a complicated mechanism is required for feeding until the final winding by the coil winding machine. It is necessary and a large space is required.

  Therefore, the coil winding machine itself can be moved by one side of the second coil portion, and as described above, a structure that can be wound by the fixing jig and the winding jig of the coil winding machine is considered. It is done.

Japanese Patent Laid-Open No. 2003-1353

However, in the wire rod processing apparatus of the above-mentioned Patent Document 1, a product obtained by bending a hook by a processing machine and processing a subtie is unloaded by a wire rod unloading device and stored in a product stacking unit. Each time, it is stored in the product accumulation section.
Therefore, for example, after feeding from one end of a long rectangular wire and sequentially winding from one end to form a square cylindrical coil portion, this time, changing the direction and feeding from the other end, etc. It is not possible to form a rectangular tube-shaped coil portion by sequentially winding from the end portion.

  Further, in the other conventional example, after winding the winding jig 90 degrees at the bending position, the winding jig is returned to the original position, and the coil winding machine is moved to one side of the rectangular wire from that position. By returning it, it will be in the state where the flat wire has been sent out for one side, where the flat wire is sandwiched between the fixing jig and the winding jig, the coil winding machine is moved to the bending position, and it is bent again. When returning the winding machine for one side of the flat wire, the flat wire is sandwiched between the fixing jig and the winding jig of the coil winding machine, so the flat wire also moves at the same time, and the winding process cannot be performed. Occurs.

In addition, when the flat wire is sent from the other end to the coil winding machine, the first coil portion formed at one end of the flat wire is formed in a rectangular tube shape, so that the weight is also heavy, so there is some support. Otherwise, there will be a problem that it hangs down from the flat wire portion.
Further, after winding the second coil part on the other end of the rectangular wire and forming a connection coil with the first coil part, a carry-out device for carrying out the connection coil is arranged, so that it is possible to manually carry out the carry-out. Becomes unnecessary, and automation can be achieved, but there is a problem that a space for disposing the unloading device and the unloading device is required.

  The present invention has been proposed in order to solve the above problems, and its purpose is to wind the second coil portion by a coil winding machine on the other end of the flat wire having the first coil portion at one end.
