That is, the parallelism maintaining part 7 is formed as a part of the peeling device main body 2 on the side facing the peeling part 6 through the notch part 5.

  The inclined part 6 a and the inclined part 6 b are at different angles with respect to the side part of the peeler body 2. That is, the angle of the inclined portion 6a with respect to the side portion of the peeler body 2 is smaller than the angle of the inclined portion 6b, and the length of the inclined portion 6a is longer than the length of the inclined portion 6b. Yes. Moreover, the front-end | tip part 6c is formed in the center position of the horizontal direction of the stripper main body 2. As shown in FIG.

  The cover tape peeling device 1 having the above-described configuration is used by being mounted on a carrier tape.

  2A and 2B are diagrams illustrating a configuration example of a carrier tape, where FIG. 2A is a perspective view and FIG. 2B is a cross-sectional view taken along line YY in the perspective view. The carrier tape 10 includes an embossed tape 11 having a plurality of storage pockets 11a formed at a predetermined interval and a large number of feed holes 11b formed at a predetermined pitch on both sides, and a cover tape 12. An electronic component 20 such as a chip resistor is stored in the storage pocket 11a in advance, and the cover tape 12 is bonded to the embossed tape 11 in the vicinity of both sides so as to cover the storage pocket 11a. The electronic component 20 is taken out from the storage pocket 11a after the cover tape 12 is peeled off.

  Next, the usage method of the cover tape peeling device 1 is demonstrated, referring FIGS. 3-5.

  3A and 3B are views for explaining a method of mounting the cover tape peeling device 1 on the carrier tape 10, wherein FIG. 3A is a perspective view, and FIG. 3B is a cross-sectional view taken along line ZZ in the perspective view. 4A and 4B are diagrams for explaining a method of peeling the cover tape by the cover tape peeler 1, wherein FIG. 4A is a schematic plan view, and FIG. 4B is a longitudinal sectional view of the cover tape peeler 1. FIG. FIG. 5 is a diagram illustrating a case where the cover tape peeling device 1 is applied to a tape feeder of an automatic mounting machine.

  First, as shown in FIG. 3, the carrier tape 10 is inserted into the guide groove 4 of the cover tape stripper 1 from the parallelism maintaining portion 7 side.

  Next, as shown in FIG. 4, the cover tape peeling device 1 has a tip 6 c of the peeling portion 6 below the substantially center of the cover tape 12 in which both side portions are bonded to the embossed tape 11 with bonding portions 12 a. Set on the side so as to sink between the embossed tape 11 and the cover tape 12. When the cover tape peeler 1 is set in this manner and the carrier tape 10 is moved in the illustrated moving direction (left direction in FIG. 4), the cover tape 12 is first moved to the position shown in FIG. It is peeled off from the embossed tape 11 at the upper adhesive portion 12a in A), and then peeled off from the embossed tape 11 at the lower adhesive portion 12a in FIG. Thereby, the peeled cover tape 12 moves in the direction deviated from the moving direction to the left side in the moving direction of the carrier tape 10.

  In order to prevent the cover tape 12 from being difficult to peel off when the carrier tape 10 is warped, the carrier tape 10 is attached to the cover tape peeler 1 by the parallelism maintaining unit 7 of the cover tape peeler 1. When inserted, the parallelism between the cover tape 12 and the peeling portion 6 is maintained, and the cover tape can be peeled smoothly.

  As described above, the cover tape stripper 1 that strips the cover tape 12 as described above can be applied to a tape feeder of an automatic mounting machine having a conventional configuration, as shown in FIG.

  In the automatic mounting machine shown in FIG. 5, first, the reel 70 around which the carrier tape 10 storing the electronic components is stored in the storage pocket 11a is attached to the tape feeder 60, and the cover tape is peeled off from the carrier tape 10 pulled out from the reel. The container 1 is mounted, and the peeling portion 6 is set so as to be embedded between the embossed tape 11 and the cover tape 12 of the carrier tape 10 after mounting. Subsequently, the carrier tape 10 from which the cover tape 12 has been peeled off by the cover tape stripper 1 is passed under the tape pressing metal 66, the tip thereof is guided to the sprocket 63, and the feed hole 11 b of the carrier tape 10 is engaged with the sprocket 63. Combine. At this time, the cover tape peeling device 1 attached to the carrier tape 10 slides when the carrier tape 10 is guided to the sprocket 63, contacts the tape pressing metal 66, and stays in the contact position. That is, the tape holding metal 66 also functions as a stopper that prevents further movement of the cover tape peeling device 1.

  Next, at the start of product manufacture, a drive source (not shown) that intermittently drives the sprocket 63 and the cover tape reel 65 is started, and the carrier tape 10 from which the cover tape 2 has been peeled off by the cover tape stripper 1 is fed. The sprocket 63 engaged with the hole 11b is intermittently fed by intermittent rotation, and the electronic component 20 stored in the exposed storage pocket 11a is taken out via the component take-out port 68 by a suction nozzle (not shown) or the like. Mount it at a predetermined place.

  Further, since the peeled cover tape 12 is displaced to the left in the moving direction of the carrier tape 10 and discharged from the cover tape peeling device 1, it is collected in a cover tape collection box (not shown) installed below the tape feeder 60. can do. Accordingly, the cover tape reel 65 in the conventional tape feeder 60 becomes unnecessary.

  It should be noted that the peeler body 2 portion of the cover tape peeler 1 prevents the parts stored in the storage pocket 11a from which the cover tape 12 has been peeled off and the lid has been removed from popping out. do.

As described above, when applied to a tape feeder of an automatic mounting machine, there are the following advantages.
(1) If you want to use the cut taping parts for an automatic mounting machine, conventionally, the cover tape is tied together to wind it around the reel 65 for the cover tape, and it is longer than the carrier tape and mounted on the tape feeder 60. I was going. If the cover tape peeling device of the present invention is used, the cut taping parts can be mounted and mounted on the tape feeder 60 as they are without joining the cover tapes.
(2) When applied to a tape feeder of a conventional automatic mounting machine, it is not necessary to wind the cover feeder around the cover tape take-up mechanism when the tape feeder is attached, leading to a reduction in attachment time. Further, when removing from the tape feeder, the working time corresponding to the removal time from the cover tape winding mechanism is shortened.
(3) Since the peeled cover tape can be recovered without using the cover tape take-up mechanism, the tape feeder can be greatly improved by making a tape feeder that does not have a cover tape take-up mechanism by improving the conventional configuration. Cost reduction is possible.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various deformation | transformation and application are possible.

  For example, in the above-described embodiment, the inclined portion 6a of the peeling portion 6 of the cover tape peeling device 1 is longer than the inclined portion 6b, but may be shorter than the inclined portion 6b. In this case, the discharge direction of the peeled cover tape 12 deviates to the right with respect to the moving direction of the carrier tape 10. In this way, the discharge direction of the peeled cover tape 12 can be controlled by slightly shifting the lengths of the inclined portions 6a and 6b in the tape moving direction. Moreover, the front-end | tip part 6c can also be made into the pointed shape. Moreover, although the material of the cover tape peeling device 1 is made of synthetic resin in the above-described embodiment, the material is not limited to this, and other materials such as metal can also be used.

  In the above-described embodiment, the cover tape peeling device 1 is separated from the tape feeder 60 when applied to the automatic mounting machine. However, as another embodiment, the cover tape peeling device 1 is replaced with the tape feeder 60. It can also be applied as an improved tape feeder that is fixed at an appropriate position (for example, a contact position with the tape retainer 67 in FIG. 5). In this case, the improved tape feeder can eliminate the cover tape take-up mechanism such as the cover tape take-up reel 65 in the conventional tape feeder 60 shown in FIG.
