Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier tape forming machine for forming a recess and a pilot hole in a tape.

[0002]

2. Description of the Related Art The configuration of a conventional carrier tape molding machine is as follows.

That is, a heat-softening tape, a conveying means for the tape, a heating means provided in a tape conveying path by the conveying means, and a molding die for forming a storage recess in a heating section of the tape by the heating means. And a punch die for forming a pilot hole in the outer peripheral portion of the storage recess downstream of the molding die.

[0004]

That is, in the above-mentioned conventional example, the formation of the storage recess by the molding die and the formation of the pilot hole by the punch die are performed simultaneously near the heating section.

However, in the case where the storage recess and the pilot hole are simultaneously formed as described above, there is a problem that an appropriate pilot hole cannot be formed.

Specifically, the tape is heated in order to form the storage recess, and the storage recess is formed in the heating portion by a molding die. The pilot hole near the storage recess is also heated. As a result, the shape of the pilot holes, the distance between the pilot holes, and the distance between the pilot holes and the storage recesses become inappropriate due to the shrinkage action when this portion is cooled.

Accordingly, an object of the present invention is to form an appropriate pilot hole.

[0008]

In order to achieve this object, the present invention provides a heat-softening tape, a means for conveying the tape, a heating means provided on a tape conveying path by the conveying means, and A molding die for forming a storage recess in a heating section of the tape by the heating means, a guide body protruding into the storage recess downstream of the molding die, and a storage recess of the tape positioned by the guide body. And a punch die for forming a pilot hole in the outer peripheral portion.

[0009] That is, with the above configuration, after the storage concave portion is formed in the heating portion of the tape by the molding die, the guide body is caused to protrude into the storage concave portion in the cooling completed area downstream thereof.
Since the pilot hole is formed in the outer peripheral portion of the storage recess in a state where the tape is positioned by the guide body, the carrier tape has an appropriate shape of the pilot hole, the distance between the pilot holes, and the distance between the pilot hole and the storage recess. Can be provided.

DETAILED DESCRIPTION OF THE INVENTION The invention of claim 1 of the present invention is directed to a heat-softening tape, a conveying means for the tape, a heating means provided on a tape conveying path by the conveying means, and a heating means. A molding die for forming a storage recess in the heating portion of the tape, a guide body protruding into the storage recess downstream of the molding die, and a pilot positioned on the outer periphery of the storage recess of the tape positioned by the guide body A punching die that forms a hole, and a carrier tape forming machine, wherein after forming a storage recess by a forming die in a heating section of the tape, a guide body is inserted into the storage recess in a cooling completion area downstream thereof, In the state where the tape is positioned by the guide body, a pilot hole is formed in the outer peripheral portion of the storage recess. Therefore, the shape of the pilot hole, the distance between the pilot holes, and the pilot hole are formed. Distance intercluster hole and the storage recess can be provided suitable carrier tape.

According to a second aspect of the present invention, there is provided a carrier tape according to the first aspect, wherein the molding die comprises a punch and a die, and the guide body is substantially similar to the punch and smaller than the punch. In the molding machine, the storage recess formed by the molding die in the heating section of the tape is thereafter cooled and shrunk, so that a guide body that protrudes into the storage recess in the downstream region is formed by a punch of the molding die. By making the punch smaller than this punch, the guide body can be inserted into the storage recess smoothly and easily, so that an appropriate pilot hole can be formed. it can.

Next, a third aspect of the present invention is the carrier tape forming machine according to the second aspect, wherein a plurality of guides are formed, and each of the plurality of guides protrudes into a recess for accommodating the tape. By projecting the plurality of guides into the storage recesses, respectively, the positional relationship between the guides and the tape can be made more appropriate, thereby forming an appropriate pilot hole on the outer periphery of the storage recess. Can be.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 2, the carrier tape forming machine according to the present embodiment comprises a heat-softening tape 1 made of polyethylene, polycarbonate, polystyrene or the like, a conveying means 2 for pulling the leading end of the tape 1, and a conveying means 2. A heating means 3 provided in the transport path of the tape 1 for heating the upper and lower surfaces of the tape 1,
, A guide body 5 protruding into the storage recess 1 a downstream of the molding die 4, and the storage recess 1 a of the tape 1 positioned by the guide body 5. Pilot hole 1b
And a punch die 6 for forming the above.

That is, square heating sections are formed in the tape 1 in order at predetermined intervals by the heating means 3, and the softened portion is punched (not shown) above the molding die 4.
Is lowered toward a lower die (not shown) to form a storage recess 1a as shown in FIG.

Next, the tape body 1 is positioned in the front and rear storage recesses 1a by pushing the guide bodies 5 from above, thereby positioning the tape 1 in the front-rear and left-right directions.
The pilot hole 1b is formed by lowering the cylindrical punch 6a constituting the above toward the die 6b having a circular hole shape.

Since the relative positions of the guide member 5 and the punch die 6 are determined in advance, if the position of the tape 1 is determined by the guide member 5, the pilot hole is effectively positioned at an appropriate position with respect to the storage recess 1a. 1b is formed.

The molding die 4 comprises a punch and a die as described above, and the guide body 5 is a quadrangular pyramid substantially similar in shape to the punch of the molding die 4, which is smaller than the punch. is there. That is, the storage recess 1a formed by the molding die 4 in the heating section of the tape 1 is subsequently cooled and shrunk, so that the guide body 5 protruding into the storage recess 1a in the downstream region is formed by the molding die 4. Although the shape is substantially similar to that of the punch described above, by making the punch smaller, the guide body 5 can be inserted into the storage recess 1a in a state where it can be positioned smoothly and easily. The hole 1b can be formed.

Further, a plurality of guide members 5, two in this embodiment, are formed, and these two guide members 5 are respectively inserted into the accommodating recesses 1 a of the tape 1 so that the guide members 5 and the tape 1 are formed. Can be made more appropriate, whereby an appropriate pilot hole 1b can be formed on the outer periphery of the storage recess 1a.

[0020]

As described above, the present invention relates to a heat-softening tape, a means for conveying the tape, a heating means provided in a tape conveying path by the conveying means, and a heating means for the tape by the heating means. Forming a receiving recess, a guide body protruding into the receiving recess downstream of the forming die, and a pilot hole formed in an outer peripheral portion of the receiving recess of the tape positioned by the guide body. Since it is equipped with a punch die, after forming a storage recess in a heating part of the tape by a molding die, a guide body is inserted into the storage recess in a cooling completion area downstream thereof, and the tape is positioned by the guide body. The pilot hole is formed in the outer peripheral portion of the storage recess after performing the above, so that the shape of the pilot hole, the distance between the pilot holes, and the distance between the pilot hole and the storage recess are reduced. It is possible to provide a switching carrier tape.
