The up-and-down moving member 37 is connected to the other end of the connecting rod 39, so that the connecting rod 39 moves the up-and-down moving member 37 downward by driving the up-and-down motor 40. The punching head 13 can be lifted and lowered by pulling and pushing upward.

  Next, the control system of the press apparatus 1 in the present embodiment will be described with reference to the block diagram of FIG. 19. In this embodiment, a main calculation unit and an image processing calculation unit each composed of a microcomputer or the like are provided. The main calculation unit and the image processing calculation unit constitute a control unit, and the image processing calculation unit is connected to the main calculation unit. The image processing calculation unit is connected to a shooting camera and stores in advance the positions of marks printed on the substrate when the arrangement position of the substrate is correct. On the other hand, the X-axis operation motor 6, the Y-axis operation motor 11, the θ-axis operation motor 27, and the elevating motor 40 are connected to the main arithmetic unit, as well as operation switches, monitors, and power supplies. Etc. are connected.

  Then, the image processing calculation unit compares the position signal of the mark 45 transmitted from the photographing camera 24 with the position information stored in advance, and if they are different, the mark is set in a preset position. As described above, the correction data is calculated and transmitted to the main calculation unit.

  On the other hand, the main calculation unit receives the correction data and controls the operations of the X-axis operation motor 6, the Y-axis operation motor 11, and the θ-axis operation motor 27 to determine the position of the punching head 3. Make corrections.

  Then, after the mark 45 reaches a preset position, the position of the mark 45 is confirmed again via the photographing camera 24, and then the lifting motor 40 is driven to mount the punching head 13 The liftable movable member 37 is lowered to punch the punching pattern 44 printed on the substrate.

  Next, the operation of the press apparatus of this embodiment configured as described above will be described. FIG. 20 is a diagram for explaining a method of punching a punching pattern printed on a substrate by the press apparatus 1 of this embodiment. In the figure, reference numeral 43 denotes a base material. That is, in the press device 1 of the present embodiment, a plurality of punching patterns 44 are printed, and a single substrate 43 having a position confirmation mark 45 printed around the punching patterns 44 is effectively provided. Applied.

  That is, when the punching pattern 44 printed on the base material 43 is punched by the press device 1 of this embodiment, the base material 43 is placed at an accurate position in relation to the punching head 13 by the operation switch in advance. The position of the mark 45 is stored in the image processing calculation unit.

  After that, the base material 43 is placed on the platform 3, and the end of the base material 43 is sandwiched by the chuck 9.

  Then, in this state, the X-axis operating motor 6 is driven to move the base material 43 into the frame 4, and the mark 45 printed on the base material 43 is photographed by the photographing camera 24. The position signal of the mark 45 is transmitted to the image processing calculation unit.

  Then, the image processing calculation unit compares the position signal of the mark 45 with the position information stored in advance, and if they are different, calculates the correction data and transmits the correction data to the main calculation unit. In response to this, the main calculation unit operates the X-axis operating motor 6, the Y-axis operating motor 11, and the θ-axis operating motor 27 to change the position of the punching head 13 to the punching pattern 44. Correct to the exact punching position. That is, the position of the punching head 13 is corrected so that the position signal of the mark 45 matches the position information stored in advance. After that, the position of the mark 45 is confirmed again by the photographing camera 24.

  After the punching head 13 is positioned at an accurate position, the lifting motor 13 is driven to lower the punching head 13, and the pattern 44 printed on the substrate 43 is punched by the blade 23. This operation is continued until all the punching patterns 44 are punched. That is, after punching one punching pattern 44, the punching head 13 is moved and the punching head 13 is moved above the other punching pattern 44 to punch the punching pattern 44. In this way, all punching patterns 44 are punched. Continue until 44 is punched out.

  At this time, in the press apparatus 1 of the present embodiment, the photographing camera 24 is disposed in the θ-axis working workpiece 19, and the mark printed on the base material from above the blade 23 is placed inside the punching head 13. Unlike conventional methods in which a sensor is placed in front of the die-cutting and the substrate is transported after detecting the mark in order to confirm the position of the mark again after shooting and further correcting the position of the substrate. It is possible to accurately match the position of the material to the blade.

  That is, when the sensor is placed in front of the mold, if the base material is displaced in the process of transporting the base material after the substrate position is detected by the sensor, no action can be taken, and the sensor is displaced. Although there is a problem that the press is performed in the state, in the press apparatus of the present embodiment, the photographing camera 24 is arranged in the θ-axis working work 19 and the position of the punching pattern from above the blade. Therefore, the marks 45 arranged around the punching pattern 44 can be confirmed with certainty, and therefore the punching pattern can be punched accurately.

  Further, in the case of a press device in which a sensor is arranged outside the die, such as when the sensor is arranged in front of the die, a plurality of punching patterns 44 are printed on a single substrate as shown in FIG. At the same time, when the mark 45 for position confirmation is printed around the punching pattern 44, the position confirmation mark enters under the punching die, so that it is impossible to confirm the position of the pattern. However, in the press apparatus of the present embodiment, since the photographing camera 24 is arranged in the θ-axis working workpiece 19, even when such a punching pattern of the base material is punched, the punching pattern can be punched accurately. Is possible.

  As described above, the position of the mark printed on the base material in the case where the base material placement position is correct is stored in advance in the image processing operation unit. Even if the position signal of the mark transmitted from the camera for shooting and the position information stored in advance coincide with each other due to the change of the pitch, the punching pattern cannot always be punched accurately. Absent. Therefore, in this embodiment, in particular, when the photographing camera is reassembled or when a new base material is used, the test punching is performed after the position of the punching head 13 is corrected. If the punching pattern cannot be punched accurately even when the position signal of the head and the position information stored in advance match, the amount of manual shift is input as offset data, and the main signal is input from the image processing calculation unit. When the correction data is transmitted to the arithmetic unit, the correction data is created in consideration of the offset data.

  The press device of the present invention photographs the mark printed on the base material above the blade for punching the pattern printed on the base material, and based on the photographing result, the punch head on which the blade is mounted, While photographing the mark printed on the base material, it is possible to correct in the X-axis direction, Y-axis direction, and θ direction, and this makes it possible to punch out the pattern accurately, so the pattern printed on the base material, etc. The present invention can be applied to all types of press devices for punching.
