Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a component assembly used in a component supply device that supplies components such as electronic components and small mechanical components to automatic machines, and particularly relates to a component assembly that is used in a component supply device that supplies components such as electronic components and small mechanical components to automatic machines. The present invention relates to a tape-shaped component assembly in which components are held in a formed recess and the recess is covered with a cover tape.

BACKGROUND ART Conventionally, a tape-shaped component assembly used in a component supply device that automatically supplies components such as electronic components is a holding tape in which components are accommodated in the recesses of a holding tape that has a number of recesses formed at a predetermined pitch along the longitudinal direction. Then, by covering this retaining tape with a cover tape and adhering it to the retaining tape with a thermoplastic adhesive layer formed on both sides of this cover tape, or by heat-sealing the retaining tape and cover tape, the recess can be removed. Generally, they are designed to prevent parts from flying out.

Then, such a tape-shaped component assembly is set in a component supply device, and after peeling off the cover tape and taking out the components inside the recess, the holding tape is cut into short pieces and disposed of. Ta.

Problems to be Solved by the Invention However, in the tape-shaped parts assembly as described above, embossing is usually performed to form recesses in the holding tape, which requires considerable cost.
When the unit price of the parts to be supplied is low, the holding tape itself accounts for a very high cost, and there is a problem in that the advantage of using a tape-shaped parts assembly is lost from a cost perspective.

Therefore, it may be possible to reduce costs by reusing the retaining tape without cutting it or discarding it, but in the case of tape-shaped component assemblies such as those described above, when the cover tape is peeled off, adhesives and It cannot be reused because the fused portion remains.

In addition, in view of this problem, as shown in FIG. 8(a), a pressure-sensitive adhesive material 23 is added to both sides of the cover tape 22, which is difficult to adhere to the other member when peeled off and can be repeatedly bonded.
It is conceivable to apply this and cover the holding tape 21 with this cover tape 22. However, even in that case, in the process of covering the holding tape 21 with the cover tape 22, if even a small amount of the pressure-sensitive adhesive 23 facing the side edge of the cover tape 22 adheres to the tension roller, it will accumulate little by little. In the end, an abnormal tension is generated at this tension portion, causing the tape to break, or when the holding tape 21 is covered with the cover tape 22 and pressure is applied from above to bond it, as shown in FIG. 8(b). As a result, the pressure sensitive adhesive 23 protrudes from the side edges of the holding tape 21 and the cover tape 22, and the protruding portion 24 adheres to the component supply device, resulting in problems such as difficulty in smoothly supplying components.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a tape-shaped parts assembly in which the holding tape can be reused and which does not suffer from various problems due to adhesion of adhesives, etc.

Means for Solving the Problems In order to achieve the above object, the tape-shaped parts assembly of the present invention includes a holding tape in which recesses for holding parts are formed at a predetermined pitch, and a cover tape that covers the recesses. , a pressure-sensitive adhesive layer that can be bonded repeatedly is formed on the cover tape along both sides thereof, and an appropriate interval is provided between the pressure-sensitive adhesive layer and the side edges of the cover tape. Features.

The pressure-sensitive adhesive layer is preferably formed by applying a pressure-sensitive adhesive to the entire surface of the cover tape and subjecting it to a treatment to lose adhesive strength except in necessary areas.

Function: According to the tape-shaped component assembly of the present invention, a pressure-sensitive adhesive layer that can be repeatedly bonded is formed along both sides of the cover tape, so that the cover tape can be repeatedly bonded to the holding tape. This makes it possible to reuse the expensive retaining tape many times, thereby reducing the cost of the tape-like component assembly. Since the spacing is set such that there is no risk of the pressure-sensitive adhesive material protruding from the side edges of the cover tape, there is no risk of abnormal tension due to adhesion of the pressure-sensitive adhesive material at the tension part of the cover tape during the process of covering the holding tape with the cover tape. Therefore, the tape does not break, and smooth movement is not obstructed when it is set in a component supply device.

In addition, to form the pressure-sensitive adhesive layer, after applying the pressure-sensitive adhesive to the entire surface of the cover tape, a process such as printing is applied to remove the adhesive force in the necessary areas. The pressure-sensitive adhesive layer can be formed easily and with high productivity while ensuring a precise interval between the pressure-sensitive adhesive layer and the side edge of the cover tape.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 7.

In FIGS. 1 to 4, l is a tape-shaped parts assembly, which is composed of a holding tape 2 made of a polyethylene resin sheet or a vinyl chloride resin sheet, and a cover tape 3 made of a polyester resin film or the like. There is. In the holding tape 2, a large number of recesses 4 are formed by embossing or the like to accommodate and hold the parts 5 at a predetermined pitch in the longitudinal direction, and on both sides of the row of these recesses 4, there are recesses 4 for adhering the cover tape 3, and A flange 6 is formed to form a feeding hole (not shown) as required. On the other hand, the cover tape 3 has the same width W as the width W of the holding tape 2, and a pressure-sensitive adhesive layer 7 that can be repeatedly bonded is formed on both sides of the cover tape 3 at portions corresponding to the flanges 6 of the holding tape 2. has been done. Further, an appropriate gap 8 is provided between this pressure-sensitive adhesive layer 7 and both side edges of the cover tape 3 so that the pressure-sensitive adhesive does not protrude from the side edges of the cover tape 3 and is not attached to the holding tape 2. It is constructed so that it does not protrude from the side edges even when pressure bonded. Further, the width e of the pressure-sensitive adhesive layer 7 is set such that the sum of the width f of the distance 8 between the cover tape 3 and the side edge of the cover tape 3 is smaller than the radius d of the crocodile portion 6, and the pressure-sensitive adhesive layer 7 The layer 7 is also prevented from being exposed to the recess 4 side.

The tape-shaped component assembly 1 having the above configuration is used by being set in a component supply device 10 as shown in FIG. That is,
The component supply device 10 includes a supply reel 11 around which a tape-shaped component assembly 1 is wound, and a tape-shaped component assembly 1 that is pulled out from the supply reel 11, fed out at a predetermined pitch, and delivered one by one to a predetermined component supply position A. A tape feeding means 12 for supplying the parts 5, a cover tape reel 13 which is driven in conjunction with the tape feeding means 12 and peels off and winds up the cover tape 3 at a position in front of the parts supply position A, and Empty tape reel 14 that winds up empty holding tape 2
It is equipped with The tape feeding means 12 is configured to feed the tape-like component assembly 1 one pitch at a time and rotationally drive the cover tape reel 13 by swinging the feeding lever 12a downward. The empty tape reel 14 is rotatably supported in parallel with the supply reel 11, and pulleys attached to both reels 13 and 14 (Fig. (not shown) A round belt 15 is wound between them.

In the above component supply device 10, the tape-shaped component assembly 1 has no pressure-sensitive adhesive protruding from its both sides, so that while the tape-shaped component assembly 1 is being fed out at a predetermined pitch by the tape feeding means 12, its guide portion The pressure-sensitive adhesive will not stick to the parts, and components will be supplied smoothly over a long period of time. Furthermore, since no pressure-sensitive adhesive is attached to the holding tape 2 wound up on the empty tape reel 14 and collected, it can be reused as is.

Further, as shown in FIG. 7, the tape-shaped parts assembly l sequentially accommodates the parts 5 in its recesses 4 at a parts supply position (not shown) while transporting the holding tape 2 in the direction of arrow B, and then this holding tape 2 is moved in the direction of arrow B. It is formed by covering the tape 2 with the cover tape 3 supplied from the reel 16 via the tension section 17 having a plurality of tension rollers 17a to 17c and bonding it under pressure with the pressure roller 18.

In this case as well, since there is no pressure-sensitive adhesive on the side edges of the cover tape 3, the pressure-sensitive adhesive protruding from the side edges may adhere to the tension roller, creating abnormal tension and causing the tape to break. Nothing like that.

In the above embodiment, a predetermined pressure-sensitive adhesive layer is formed by applying pressure-sensitive adhesive in a narrow width to both sides of the cover tape 3 so that an appropriate gap 8 is formed between the cover tape 3 and the side edges of the cover tape 3. 7 has been shown, but the method for forming this pressure-sensitive adhesive layer 7 is as shown in FIG. By applying the straw material leaving the area that should become the pressure-sensitive adhesive layer 7, the area other than the pressure-sensitive adhesive layer 7 becomes the non-adhesive area 1.
In this embodiment, after applying the pressure-sensitive adhesive to the entire surface of the wide sheet or film, a straw material that loses adhesive strength is applied in a pattern corresponding to the non-adhesive area 19 of each cover tape 3. By printing and then separating and cutting each cover tape 3 with a slitter, the cover tape 3 in which a predetermined interval 8 between the side edge of the cover tape 3 and the pressure-sensitive adhesive layer 7 is provided with high accuracy can be produced with high productivity. Can be manufactured well.

In addition, as the above-mentioned pressure-sensitive adhesive material, it is preferable to use an adhesive made of a polymer made of linearly bonded acrylic acid and alcohol esters, and as a straw material that causes the adhesive force to be lost, the above-mentioned polymer By using a mixture of ultraviolet curable resin in the body, adhesive force can be eliminated by irradiating ultraviolet rays after printing and bonding the polymer and the ultraviolet curable resin to eliminate fluidity.

Effects of the Invention According to the tape-shaped component assembly of the present invention, as is clear from the above description, a pressure-sensitive adhesive layer that can be repeatedly bonded is formed along both sides of the cover tape, so that the holding tape The cover tape can be repeatedly bonded to the tape, and the expensive holding tape can be reused many times, thereby reducing the cost of the tape-shaped component assembly.

Moreover, since there is an appropriate gap between the pressure-sensitive adhesive layer and the side edge of the cover tape, there is no risk that the pressure-sensitive adhesive will protrude from the side edge of the cover tape, and the cover tape can be applied over the holding tape. It exhibits great effects, such as preventing the tape from breaking due to abnormal tension due to the adhesion of the pressure-sensitive adhesive in the covering process, and preventing smooth movement when set in the parts supply device.

In addition, after applying pressure-sensitive adhesive to the entire surface of the cover tape, if a pressure-sensitive adhesive layer is formed by applying a treatment to lose adhesive strength except for necessary areas, the pressure-sensitive adhesive can be applied by printing or other means. A cover tape in which the interval between the layer and the side edge of the cover tape is ensured with high accuracy can be manufactured with high productivity.
