Field of the Invention The present invention winds a tape for taping loaded with various chip-like components such as a square plate type chip fixed resistor, a chip type capacitor, a cylindrical leadless type fixed resistor and the like on a reel. After that, the end of the leader is fixed to the outer peripheral surface of the taping tape to hold the tape in the wound state, and the taping used to peel off the leader from the taping tape when removing the chip-shaped component. TECHNICAL FIELD The present invention relates to an end tape manufacturing apparatus for winding a tape for use.

[0002]

2. Description of the Related Art Conventionally, taping tapes for taping chip-shaped components are roughly classified into two types.

FIGS. 26A and 26B show an example of a conventional taping tape T. FIG. The taping tape T is composed of a loading tape T1 and a cover tape T2. The loading tape T1 is provided with a plastic film bottom tape T4 on the back surface of a paper tape body T3 having holes arranged in rows. Recessed portion T5 to be loaded with a chip-shaped component
Are formed.

FIGS. 27A and 27B show another example of a conventional taping tape T. FIG. The taping tape T is composed of a loading tape T1 and a cover tape T2. The loading tape T1 is made of plastic, and a recess T5 for loading a chip-like component is formed by press molding.

[0005] In order to perform taping of a chip-shaped component (for example, a square plate-type chip fixed resistor) R using such a taping tape T, first, the chip-shaped component R is inserted into the recessed portion T5 of the loading tape T1. After that, a cover tape T2 made of a plastic film is heat-sealed to the surface of the loading tape T1. At this time, the cover tape T2 is heat-sealed so as not to close the feed holes T6 arranged in the side of the loading tape T1.

In any of the above taping tapes T, when the chip-shaped component R is taken out, the loading tape T1 is used.
As shown in FIGS. 24 and 25, the chip-shaped component R is not loaded into the recessed portion T5 for each desired length of the loading tape T1 at the time of the taping operation so that the cover tape T2 can be easily peeled off from the cover tape T2. Leave the empty part,
In this empty portion, a separation portion Ta where the cover tape T2 is not thermally fused to the loading tape T1 is left. First, at the rear position C1 in the separation section Ta, the loading tape T
1 and the cover tape T2 are cut together, and then only the loading tape T1 is cut at the front position C2 in the separation portion Ta, and a leader portion T2a projecting rearward from the loading tape T1 is formed on the cover tape T2. If necessary, as shown in FIG. 25, in order to form the leading end of the next taping tape T, the loading tape T1 and the cover tape T are located at a position C3 slightly behind the cut section Ta.
Cut 2 together.

[0007] The operation of forming the leader portion T2a is performed while winding the taping tape T, and the formed leader portion T2a is fixed to the outer peripheral surface of the taping tape T with an end tape. Conventionally, dedicated end tapes have been used. That is, as shown in the plan view of FIG. 28, the end tape E is provided with an adhesive layer on one surface except for a non-adhesive portion (shown by oblique lines) E1 at one end.

m, a total of about 92 mm, which can be considerably shorter than the conventional dedicated end tape E of 150 mm in length. In this regard, it is also possible to reduce costs in comparison with the conventional example. Becomes

In the above embodiment, after the winding end tape te is attached to the leader portion T2a of the taping tape T, the pressing member 74 is separated from the receiving surface 27 of the wheel 21 by the release device 86. It is rotated to release the peeling knob tg. However, if there is no fear that the winding end tape te is separated from the tape guide groove 26 of the wheel 21, the winding end tape tg
Before attaching e to the leader portion T2a, the peeling knob portion tg
May be released. The winding end tape manufacturing apparatus of the present invention can be applied to a leader section forming apparatus of a type other than the above-described leader section forming apparatus. In addition, the present invention can be variously changed in design without departing from the basic technical idea.

[0050]

As described above, according to the present invention, the adhesive tape supplied from the supply device to the tape guide groove of the wheel is cut by the cutting device in the recess, and the cut end is cut by the double bending device. Bend so as to be double, press this bent part against the receiving surface by the pressing member of the superposition device,
Pressing member from the receiving surface when sticking in a superposed state to form a peeling knob, and applying the winding end tape with this peeling knob formed to the leader part at the end of the taping tape Separate and release the release knob. In this way, the commercially available adhesive tape is cut to produce a winding end tape having a peeling knob portion which is a non-adhesive portion, and a leader portion at the end of the taping tape wound by the winding end tape. Can be fixed to the outer peripheral surface of the taping tape. Therefore, cost can be reduced by eliminating waste of materials.

Further, by providing a suction device for sucking the winding end tape into the tape guide groove of the wheel, the operation of manufacturing the winding end tape can be reliably performed in a stable state, and the device can be made compact. Can be put together.

Further, the recesses are formed at a plurality of locations at evenly divided positions, and a winding end tape is produced between adjacent recesses, so that the winding end tape is adhered to the leader portion. Since the winding end tape can be manufactured in between, the efficiency of the manufacturing operation can be improved, and the cost can be further reduced by shortening the winding end tape.
