[Problems to be solved by the device]

 In the conventional stand-type supply device, when the wire rod is unwound and pulled up from one wire rod stand where the guide sheave is located immediately below it, and when the worker moves to the next spare wire rod stand, the worker always moves to the next spare wire rod stand. It was necessary to move the wire directly under the guide sheave and reposition it, and guide the wire rod to the guide sheave manually. However, the worker moves the spare wire rod stand by hand, then pays out the wire rod from the spare wire rod stand and guides it to the guide sheave, and the work speed of the worker and the wire rod of the guide sheave. Since the pulling speed did not match, it was often the case that workers could not smoothly deliver the wire rod from the spare wire rod stand that was moved every turn. Therefore, excessive tensile stress acts on the pulled-up wire rod to break the wire rod, or the winding wire rod is pulled up from the spare wire rod stand to the guide sheave at the same time for 2 to 3 turns. Occasionally, there was an accident in which the wire was broken or the tensile forces acted on each other to cause back tension and disconnection.

Furthermore, the worker must always check the amount of remaining wire rods in the wire rod stand in preparation for the movement of the wire rod stand, and when the drawing and feeding of the wire rods from one wire rod stand is completed, the empty wire rods are emptied. The load on the operator was heavy, such as moving the wire rod stand and guiding the wire rod from the new wire rod stand to the guide sheave. In view of the above problems, an object of the present invention is to automatically rewind and withdraw the wire wound on the adjacent spare wire stand when the supply of the rewind drawer for the wire wound on one wire stand is completed. The objective is to provide a stand-type supply device that can be transitioned in a simple and accurate manner.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a stand type supply device according to the present invention is a group of wire rod stands in which a plurality of wire rod stands having a wire rod holding portion formed in a vertical tubular shape by a frame or a wall on a bottom plate are arranged in parallel. The wire rod is wound around each wire rod holder of the wire rod stand, and the wire rod winding end end of one wire rod stand and the wire rod start end of the adjacent spare wire rod stand extend between them. The wire rods are connected to each other to form a continuous wire rod through all the wire rod stands of the wire rod stand group.Furthermore, the wire rod is positioned almost directly above the wire rod stand described above and wound around the wire rod stand. The guide sheave that revolves around the horizontal axis that guides the wire rod in a predetermined direction while rewinding it, the guide column that guides the connected wire rod to the guide sheave, and the connected wire rod that guides the guide wire. It is equipped with a detector that detects that it is being pulled up by the cable and outputs the detection signal, and a wire rod guide device installed between the adjacent wire rod stands and a guide sheave that receives the detection signal. It is characterized by having a moving device that moves almost directly above the spare wire rod stand next to the one wire rod stand.
