Description

  The present invention relates to cutting and pulling out a winding of a winding body (hereinafter sometimes simply referred to as “winding body”) comprising a core of a motor of a washing machine or the like and a winding wound around the core. The present invention relates to a winding recovery device for a winding body and a winding recovery method for a winding body.

The Home Appliance Recycling Law was enacted in April 2001, and it is obliged for distributors to take home appliances such as air conditioners, refrigerators, TVs, and washing machines and to recycle them by manufacturers. For this reason, it is necessary to cut | disconnect a coil | winding body used for these household appliances, and to isolate | separate into a coil | winding and a core, and to use for recycling.
Conventionally, as a method of cutting the winding of the winding body, for example, a method of cutting by rotating or reciprocating a blade such as a saw or a grindstone has been performed. However, in the method of cutting the winding of the winding body with the saw, grindstone, etc., a large amount of chips are generated with the cutting, and dust damage is caused, and the copper constituting the winding is very soft, It is pulled out of the core without being cut and bent, resulting in a large amount of cutting leakage and defective cutting. When such cut-off and cutting failure occur, there is a problem that it is difficult to separate the winding from the core due to the winding and the core being caught at the portion.

  Therefore, for example, as shown in FIG. 1, a winding body holding mechanism 110 that holds a cylindrical winding body M composed of a core and a winding in a hollow portion, and a winding held by the winding body holding mechanism 110. A winding body rotation mechanism 20 that intermittently rotates the wire body M by a predetermined angle; and a cutting blade mechanism 30 that includes a pair of cutting blades 31 that sandwich a winding protruding from the end face of the core from the inside and outside in the radial direction; The intermittent movement of the proximity movement mechanism 40 that relatively moves the cutting blade mechanism 30 and the winding body M so that the winding is sandwiched between the cutting blades 31 and the winding body rotation mechanism 20. And a cutting blade driving mechanism 50 that cuts the cutting blades 31 by bringing the cutting blades 31 close to each other and cutting the windings in conjunction with each other (see Patent Document 1). ). In FIG. 1, 14 is a winding body holding member, 32 is a cutting blade holding member, 33 is a cutting blade holding member holding mechanism, 42 is a hydraulic cylinder, and 59 is a hydraulic pump.

  However, in the proposed winding cutting device, after the winding of the winding body is cut, the cut winding body is removed from the cutting device of the winding body, and another winding body is further removed. Therefore, there is a problem that it is impossible to continuously process from cutting to drawing of the winding. Further, in the winding cutting device of the proposed winding body, because it is held using the hollow portion of the cylindrical winding body, it can only be fixed in the radial direction of the core of the winding body, There is a problem that it is difficult to stably fix the core in a winding body in which there are many types of core thickness, shape, and size.
