Description

  In the present invention, a wire made of a fine wire such as an IC wire is fed out from an unwinding spool that is a long spool, and the leading end of the wire is used as a take-up spool that is a shipping spool with a predetermined adhesive tape. The present invention relates to an automatic wire winding device that automatically performs a process from pasting to winding by a set length and pasting a wire end to a predetermined adhesive tape.

  The wire is usually made into an ultrathin wire by a wire drawing process, subjected to heat treatment, wound on a long spool, and once stored. Thereafter, before shipping, the wire is wound from a long spool to a small shipping spool for products using a wire automatic winding device at a set length.

  The conventional rewinding operation will be described in detail below. 6 is a perspective view showing a conventional automatic wire winding device, and FIG. 7 is a perspective view showing the winding spool shown in FIG.

  First, the take-up spool (3) which is a shipping spool is set on the take-up shaft of the automatic wire take-up device, and the tip of the wire (1) is fed out from the take-up spool (6) which is a long spool. Press against the outside or inside of the flange (3a) on one side of the take-up spool (3), sandwich the adhesive tape (4) cut in advance with tweezers, and attach the tip of the wire (1) to the flange (3a) wear. After the excess wire (1) protruding from the adhesive tape (4) is cut, the start switch of the automatic wire winding device is pushed to start rewinding. In addition, as in the flange (3a) on the other side in FIG. 7, when the tip of the wire (1) is affixed to the inside of the flange (3a), it is left as it is, but the front flange (3a) in FIG. When the tip of the wire (1) is affixed to the outside of the flange (3a), the wire (1) is moved inward through the groove (3b) machined in one place on the outer periphery of the flange (3a). Let Thereafter, rewinding is started.

  Next, after winding the wire (1) of the set length onto the take-up spool (3) and finishing the rewinding, the end of the wire (1) is directly pinched inside the flange (3a) with tweezers. Adhere with adhesive tape (4). Alternatively, after the end of the wire (1) is passed over the outside of the flange (3a) through the groove (3b), the end of the wire (1) is placed outside the flange (3a) with tweezers (4 ) Thereafter, the excess wire (1) protruding from the adhesive tape (4) is cut, and finally the take-up spool (3) is removed from the wire automatic take-up device.

  However, since the wire (1) is an extra fine wire and the adhesive tape (4) is small, the above operation requires an operation using tweezers. The position where the adhesive tape (4) is applied, the adhesive tape (4) Differences in the pressing force and work speed for each worker occurred, which hindered quality and productivity. In addition, due to the manual work of the worker, the number of winding devices that one worker can handle in parallel is limited, and the ratio of labor costs to production costs is high, which is an obstacle to cost reduction. It was.

  As a conventional automatic wire winding device, for example, Japanese Patent No. 2747256 describes a coil winding method and device for winding a copper wire around a bobbin. However, since a scratch is generated by the guide portion that is a nozzle, it is difficult to apply to a wire that is a fine wire, and the bobbin needs to have a structure for fixing the tip and end was there.

"First step"
First, the operator unwinds the wire (1) from the unwinding spool, and passes the grooves of the tension detection pulley (8) and the guide pulley (2) in the same manner as in the conventional automatic wire winding device shown in FIG. Thereafter, the wire (1) is clamped by the fixed clamp mechanism (210) as shown in FIG.

"Second step"
In the second step, after the moving clamp mechanism (220) clamps the wire (1), the fixed clamp mechanism (210) releases the wire (1) and moves horizontally to the rear side of the take-up spool (3). And wait. The moving clamp mechanism (220) that clamps the wire (1) is arranged in front of the take-up spool (3) so that the middle of the wire (1) is along the outside of the flange (3a) of the take-up spool (3).

Thereafter, after the rewinding is completed at a preset winding length, the end of the wire (1) is attached to the flange (3a) in the same manner as in the third to fifth steps described above, and the operation is completed. . When the end of the wire (1) is pasted outside the flange (3b) of the spool (3), the same process as the sixth to eighth processes is performed in advance, and then the above-mentioned first process is performed. What is necessary is just to perform the process similar to a 3rd process-a 5th process.
