The present invention relates to a punching device for punching a tape-like material used for a flexible substrate or the like, such as a hip size package, in a predetermined punching pattern while feeding the same from a roll.

[0002]

2. Description of the Related Art Conventionally, a punching device of this type has a tape-shaped object provided with a plurality of reference marks such as sprocket holes formed along each of both edges, and the tape-shaped object is measured from a roll material. An XY punch comprising a plurality of punch units each having a punch and a corresponding die between a feeding mechanism for feeding and a winding mechanism for winding the same, and a camera unit arranged in parallel with the punch. Provided so as to be controllable in the direction, the camera unit images the fiducial mark, the drilling machine drills a fiducial hole on predetermined coordinates from the fiducial mark, and in a boring area based on the fiducial hole. The drilling machine is configured to perform drilling in a predetermined drilling pattern. This conventional punching device includes two cameras in the camera unit.These cameras image the reference marks on both edges of the tape-shaped object, and the two images are used as a reference. The punch drills a reference hole on predetermined coordinates between the reference marks, and one of the two cameras moves to a position corresponding to the reference hole,
An image of the reference hole is taken, and the drilling machine drills the hole with high precision in a predetermined drilling pattern using the reference hole as a reference point.

[0003] However, in the conventional drilling device,
As shown in FIG. 6, since the two cameras 310 and 310 are located on both sides of the tape-shaped object 100 to capture the reference marks 111 and 112, respectively, Reference hole 120 drilled between
Takes a long time to move to the position corresponding to,
When the reference hole 120 is set so as to be drilled at substantially the center of the reference marks 111 and 112, one of the cameras 1
30 must move a long distance, which is about half of the width of the tape-shaped object 100. Since the movement of the camera 130 as described above is performed every time the tape-shaped material 100 is pierced through the product hole 131 in the perforation area 130 and is fed in a fixed amount, the piercing of one tape-shaped material 100 is completed. By then, it was a huge time loss.

[0004]

And a second reference hole camera disposed between the second reference mark camera and the third reference mark camera and imaging the second reference hole.

According to the above technical means, the present invention has the following operations. The reference marks in a plurality of rows are imaged by a reference mark camera provided exclusively for imaging with respect to each reference mark, and the reference holes drilled by the drilling machine are the reference holes provided exclusively for imaging with respect to the reference holes. The image is taken by the hole camera. Therefore, the movement of the reference mark camera is in a range near the reference mark above or below the tape-shaped object. The movement of the reference hole camera is in a range near the reference hole above or below the tape-shaped object.

Reference numeral 2 denotes a sprocket hole that engages with the tooth tips of the sprocket wheel 12 and the sprocket wheel 22.
These reference marks 111.112 are used to connect the feeding mechanism 10 and the winding mechanism 20 to the sprocket wheels 12, 22.
If the tape-like material 100 is configured to be guided by a roller or the like instead of the sprocket hole, a printed circular mark or the like may be used instead of the sprocket hole.

The punch 30 includes a plurality of punch units 31 and punches 31a having different shapes and sizes.
Then, a reference hole 120 and a plurality of product holes 131 based on the reference hole 120 are formed in the perforated area 130 of the tape-shaped material 100 by a die 31b corresponding to the punch 31a.

The punch unit 31 has a U-shape in a side view as viewed from the side, with a central horizontally long space as a space for carrying the tape-shaped material 100. The punch unit 31 is provided with an exchangeable punch 31a in an upper half and a lower half. The die 31b corresponds to the punch 31a.

In the longitudinal direction) and in the Y-axis direction.

Thus, according to the drilling device A having the above configuration,
The tape-shaped object 100 is provided with the feeding mechanism 10 and the winding mechanism 20
The first reference mark camera 211 takes an image of the first reference mark 111 and the second reference mark camera 212 takes an image of the second reference mark 112 each time.

The reference hole 120 is formed by moving by 0. At this time, since the reference hole 120 is perforated based on the two reference marks 111 and 112, even if the tape-like material 100 is not completely carried into the punch unit 31 at a right angle due to a mechanical error or the like, the reference hole 120 is not removed. The hole is accurately drilled at a predetermined location based on the reference marks 111 and 112 of the points. Next, the reference hole camera 220 is moved on the coordinates of the reference hole 120 by the XY moving mechanism 40 to capture an image of the reference hole 120, and the center coordinates are recognized by the image processing unit through image processing.

m, 96 mm and the like. Therefore, when the pitch is changed by exchanging the tape-shaped object 100 with one having a different width, after measuring the corresponding reference mark by one reference mark camera, the other reference mark camera is moved in the XY direction. The other reference mark is imaged by moving in the width direction of the tape-like material having the pitch difference by the mechanism 40. For example, when a tape-like material having a pitch of 35 mm is initially set and the tape-like material is replaced with a tape-like material having a pitch of 48 mm with the first reference mark 111 corresponding to the camera 211 for the first reference mark, After imaging the first fiducial mark 111 with the one fiducial mark camera 211, the camera unit 200 is
