The slide table 20 has a holder cutter described later. 18 is provided, and this holder cutter 18 is configured to be opened and closed by a cylinder mechanism 17. As shown in the configuration diagram of FIG. 4, the holder cutter 18 is composed of a fixed side portion and a movable side portion. The fixed side portion sandwiches a rubber material 23a between a holding plate 24a and a fixed blade 18a, and these are held by a holding metal fitting 26. It is fixed together. In the movable side portion, the rubber material 23b is sandwiched between the pressing plate 24b, the pressing plate 25 and the moving blade 18b, and the moving blade 18b is supported by the pressing metal fitting 27 so that the moving blade 18b can be opened and closed.
It is designed to be opened and closed by. With such a configuration, when the moving blade 18b is closed by the cylinder mechanism 17 sandwiching the tape 6a in the opened state, the tape 6a is held by the rubber materials 23a and 23b, and subsequently the cutting edges 18a 'and 18b' thereof. Is cut by.

Next, the operation of the taping device configured as described above will be described. First of all, as shown in FIG.
After being positioned at the coil winding start end, the support base 1 travels along the shape of the coil 4 in response to a travel command, and at the same time, receives the direction control of the frame 2 so that the rotating ring 3 crosses the coil 4 at a right angle. Keep it and start spinning. When the rotary ring 3 starts to rotate, the holder cutter 18 is retracted by the cylinder mechanism 19 together with the slide table 20 in the direction of arrow D'as shown in FIG. Tape 6a
The tape 6a is wound around the outer circumference of the coil 4 by rotating the rotating ring 3 around the coil 4 while the tape end 6a 'of the tape 6 is held by the holder cutter 18 by the method described later. After that, the tape 6a is wound around the coil 4 several times, so that the winding start end of the coil 4 is pressed by the tape 6a that is continuously wound thereafter and fixed to the coil 4. When the tape winding start end is fixed as described above, the holder cutter 18 is opened by the cylinder mechanism 17 as shown at 18 'and the tape end 6a' is opened. The opened tape end 6a 'is processed so as to be buried in the tape 6a which is fed from the tape roll 6 continuously running and rotating and wound. In this way, the unattended automatic processing of the tape winding start end is completed.

Subsequently, the support base 1 and the rotary ring 3 are continuously taped to the coil 4 by traveling and rotating along the coil 4. Then, when taping is completed within a predetermined range of the coil 4, the support base 1 and the rotating ring 3 are
Will stop. After the stop, as shown in FIG. 3, the adhesive applying device 15 is moved in the direction of the arrow B'by a cylinder mechanism (not shown) to move to a position facing the spindle 11 with the coil 4 as the center, and further not shown. The cylinder mechanism moves in the direction of arrow C'to move the tip 16 'of the jet nozzle 16 to the final position of the tape 6a wound around the coil 4 at the position shown by the broken line 15' in the figure. Here, the adhesive is ejected from the ejection hole (not shown) provided at the tip 16 'of the ejection nozzle 16 onto the final tape around which the adhesive is wound. This ejection is performed by a high pressure air system (not shown). After the adhesive is ejected, the adhesive ejecting device 15 is returned to the position shown in FIG. 1 by a cylinder mechanism (not shown). Next, the slide base 20 is moved by the cylinder mechanism 19 as shown by the arrow D'in FIG.
Holder cutter 18 that operates in the direction opposite to
Stops before being wound around the coil 4 and sandwiches the tensioned tape 6a, and then the cylinder cutter 17 causes the holder cutter 18 to hold and cut the closed tape 6a.

This operation will be described with reference to FIG. FIG. 4 is a cross-sectional view of the holder cutter, in which the holder cutter 18 in the open state sandwiches the tape 6a, and the cylinder 1
A closed state occurs due to 7. Open the holder cutter 18 and insert the tape 6a into the cylinder mechanism 1
When it is closed by 7, the rubber members 23a and 23b are first
Hold the tape 6a (c part), and then the cutting edge 18
The tape 6a is cut by a'and 18b '. The cut tape 6a is held by the rubber members 23a and 23b on the side of the tape roll 6 in FIG. 1 as the tape end 6a ', and the side of the coil 4 is divided into the winding end 6b' as shown in FIG.

The holder cutter 18 holding the tape end 6a 'as described above is returned to the position shown in FIG. 1 by the cylinder mechanism 17. Next, the tape end 6b 'remaining on the coil 4 side is rotated by the cylinder mechanism 13 shown in FIG.
1 is extruded and processed. That is, as shown in FIG. 5, the spindle 11 of the rotary ring 3 is stopped at the position of the cylinder mechanism 13 by the position control sensor (not shown) embedded in the rotary ring 3, and at this point, the adhesive is ejected. Also, the tape is cut. When this operation is completed, the cylinder mechanism 13 operates and its rod end 13 'comes into contact with the pushing end 11' of the spindle 11 and is further pushed forward. By this operation, the holding tool 14 attached to the other end of the spindle 11 can hold the free tape end 6b 'on the final winding tape from which the adhesive has been ejected, and the winding 4 is wound around the coil 4 before. The tape 6a is fixed by an adhesive. As described above, the unmanned automatic processing of the winding end is completed. FIG. 3 shows this state. After that, since the rod of the cylinder mechanism 13 is sucked, the spindle 11 returns to the rear by the spring 10, and the entire mechanism returns to the state shown in FIG.

〔The invention's effect〕

According to the present invention described above, since a series of taping from the winding start end to the winding end of the tape can be continuously processed, it is possible to unmanned the taping, which requires the most manufacturing time in coil manufacturing. It is possible to provide a taping device that can reduce the manufacturing time of the coil and the like and can reduce the cost.
