2. Description of the Related Art In recent years, electronic control has been advanced in automobiles and the like, and it has become necessary to provide a large number of wires for doors and lights. In order to efficiently provide such a large number of wirings, a flat wiring body (Flexible Flat Circuit) in which both surfaces of a copper foil wiring pattern are covered with an insulating layer has been developed and widely used. For example, a flat wiring body used for an automobile rear light includes a punching pattern 52 (a plurality of punching pattern groups in which a plurality of punching wiring patterns 55... Are provided at a predetermined pitch in a longitudinal direction of a belt-like sheet body 51 as shown in FIG. 18). ) Is produced by stamping.
At this time, the strip-shaped sheet body 51 is sent to the outer shape punching device 54 at a predetermined pitch through mark detection means 53 (such as an optical sensor or a proximity sensor) provided in the middle of the transport line, and is punched by the outer shape punching device 54. As shown in FIG. 21 (a), a cut 61 is made on the outer periphery of the wiring pattern 55 of the punching portion 52 by the blade, and thereafter, the punched portion 52 is sent to a downstream product storage device as a product and the remaining scrap portion is formed. Is separated into

(Return to FIG. 18) By the way, conventionally,
When the punching portion 52 of the band-shaped sheet body 51 moves to the outer shape punching device 54, the position of the punching portion 52 may be shifted from the punching position of the punching blade. Fine adjustment was made in the direction (X direction) and the width direction (Y direction). In other words, referring to the flow charts of FIGS. 18, 19 and 20, the U-shaped mark portions 56 provided at a predetermined pitch in the longitudinal direction of the band-shaped sheet body 51 are shown in FIG.
When sent to the mark detecting means 53 (as shown in FIG. 19 (a)), the width direction line 59 of the mark portion 56 comes to the feed direction detecting position 57 of the mark detecting means 53 (as shown in FIG. 19 (b)). Mark detecting means by feeding the belt-shaped sheet member 51 in the X direction at a low speed.
The operation is stopped by the input of the mark 53 and the mark section 56 is placed at the width direction detection position 58 of the mark detection means 53 (as shown in FIG. 19C).

An arithmetic storage means 49 is provided for calculating and storing the movement correction amount of the punching blade 9 (see FIG. 6) of the outer shape punching device 1 based on the detection data of the positions 8 and 38.

Thus, as shown in the flow charts of FIGS. 1, 14 and 17, the punching positioning method using the punching device has a strip shape having a punching portion 4 and a mark portion 38 provided at a predetermined pitch L in the longitudinal direction. The sheet body 3 is conveyed to the outer shape punching device 1 by a predetermined pitch L, and a punching blade 9 (see FIG. 6) provided on the outer shape punching device 1 so as to be adjustable in a horizontal plane is set to a punching position corresponding to the punching portion 4. This is a positioning method. First, when the mark portions 38, 38 forming a left and right pair move to the mark detection means 2, 2 provided on the upstream side of the conveyance from the outer shape removing device 1, the feeding of the band-shaped sheet body 3 is stopped. And the band-shaped sheet 3

Each of the detected mark portions 38, 38
Calculation storage means based on the detection data of the 38 XY coordinate positions
The movement correction amount is calculated by 49. That is, the arithmetic storage means 49 calculates the shift amount in the X direction and the shift amount in the Y direction for each of the mark portions 38, 38, and calculates the shift angle of the pair of mark portions 38, 38 with respect to the center C. These values are the movement correction amount of the punching die 8 (big type) of the external shape punching device 1 (described in FIG. 3) ３the deviation angle θ,
The X direction correction amount and the Y direction correction amount 記憶 are stored.

Thereafter, as shown in FIG. 14 and FIG.
When the mark portions 38, 38 detected by the mark detection means 2, 2 are sent by one pitch or more and moved to the outline removing device 1,
Based on the movement correction amount stored in the arithmetic storage means 49,
As shown in FIG. 16B, the position of the punching die 8 and the punching blade 9 is adjusted in the horizontal plane (the deviation angle θ and the positions in the X and Y directions are adjusted). At this time, the movement correction amount data is input from the arithmetic storage unit 49 to a control unit (not shown), and the control unit drives and controls the position adjustment mechanism unit 10 of the outer shape removing device 1. As described above, since the position of the punching blade 9 is adjusted not only in the feed direction and the width direction but also for the deviation angle θ, the upper platen 6 is lowered thereafter.
The cut edge can be accurately formed (outlined) with a predetermined margin M on the outer periphery of the punched portion 4 by the punching blade 9. At this time, the pressure applied to the punching die 8 by the press can be received by the upper platen 6.

Further, according to the punch positioning method of the present invention,
When detecting the mark portions 38 by the mark detecting means 2, the width direction position of the metal foil portion 39 (described above) provided at a predetermined pitch L in the longitudinal direction on the belt-shaped sheet body 3 is determined by the first eddy current detector. 48, and thereafter, when the mark portions 38, 38 detected by the mark detection means 2, 2 have moved to the outline removing device 1, the metal foil portion 39 detected by the first eddy current detector 48 Can be detected by the second eddy current detector 37 and used as auxiliary data for positioning in the width direction.

More specifically, when the mark portions 38, 38 of the belt-shaped sheet member 3 move to the mark detecting means 2, 2, one of the left and right edges 50 of the metal foil portion 39 becomes the first eddy current detector.
The first eddy current detector 48 detects the position of the metal foil portion 39 in the width direction as shown in FIG. That is, the first eddy current detector 48 and the metal foil 39
The eddy current in the overlapping portion G is detected, and the detected value of the eddy current is stored as the position in the width direction of the metal foil portion 39 in the arithmetic storage means 49 (see FIG. 10).

Thereafter, as shown in FIGS. 14 and 15, when the metal foil portion 39 moves from the first eddy current detector 48 to the second eddy current detector 37, it slightly shifts in the width direction (Y direction). In some cases, the eddy current in the overlapping portion G of the second eddy current detector 37 and the metal foil portion 39 is detected, and the eddy current detected by the first eddy current detector 48 is compared with the operation storage means 49. The numerical value of the difference is used as auxiliary data for positioning in the width direction. Then, based on the detected data of the positions of the mark portions 38, 38, the arithmetic storage means
Movement correction amount calculated and stored in 49 (Y direction correction amount)
In addition, the above-described auxiliary data is added to determine a final movement correction amount, and based on the final movement correction amount,
As shown in FIG. 3 and FIG.
Is positioned and adjusted in the horizontal plane. Therefore, the outer shape can be removed with higher accuracy. When the auxiliary data (numerical value) is 0, the movement correction amount stored in advance in the arithmetic storage unit 49 becomes the final movement correction amount.

The present invention is not limited to the above-described embodiment. For example, in the present embodiment, the method of punching and positioning without the outer shape of the flat wiring body has been described. Can be widely applied. Further, the position adjusting mechanism section 10 may have a configuration in which the first unit 14 is disposed on the downstream side and the second unit 15 is disposed on the upstream side (inverted by 180 ° in a plane as a whole).

At this time, the mark part 38,
When the position of 38 is detected and the movement correction amount of the punching blade 9 is stored, and the mark portions 38, 38 are moved to the outer shape punching device 1 at least one pitch downstream to perform the outer shape punching of the punching portion 4. In addition, since the position adjustment (correction) of the punching blade 9 can be performed with the movement correction amount stored in advance, there is no influence of the pitch error (as in the related art).

According to the fifth aspect, the punching die 8 can be attached to the upper platen 6 of the press machine 11 by the position adjusting mechanism 10 so that the position can be adjusted in a horizontal plane. That is, the existing press machine 11 can be used, and the outer shape punching device 1 can be manufactured at low cost.

According to the sixth aspect, the swinging mechanism 16, the feeding direction moving mechanism 17, and the width direction moving mechanism 18 adjust the deviation angle θ between the punching die 8 and the punching blade 9, and adjust the feeding direction (X Direction) position adjustment and width direction (Y direction) position adjustment can be divided, so that the structure of the position adjustment mechanism 10 as a whole can be simplified and drive control can be easily performed.
