昭63−180653号公報)。[0003] Various proposals have been made to solve these problems, but one of them is to install a large number of rotating rollers on a conveyor that conveys a plate-like object such as a buried frame. A device for preventing double stacking of plate-like objects is known, which utilizes the fact that a plate-like object is intermittently pushed up at a predetermined position by an arm, and the moment acting on the arm changes depending on the weight of the plate-like object at that time.

うにしておけばよい。A is a plate-shaped object such as a lead frame, which is stacked on a stacker (not shown) after the previous process has been completed. Reference numeral 1 denotes a holder, which has a pair of claws 1a and 1b, and has a file-shaped tip that can pinch and take out the plate-like object A from the stacker and transport it. 2 is a guide part,
It consists of a pair of guide plates 2a and 2b that are parallel to each other and whose mutual interval can be arbitrarily adjusted, each having a groove 2c formed inside the upper edge thereof, on which the plate-like object A is placed, for example, By pushing with a pusher (not shown), the plate-like object A can be conveyed along the guide plates 2a, 2b in the direction of extension of the guide plates 2a, 2b. Reference numeral 3 denotes a measuring element, the lower surface 3a of which is a horizontal surface, and one end of which is a vertical portion 3.
b, and a detection part 3c is formed extending from the central part of the side surface of the vertical part 3b in a direction parallel to the guide plate 2b.
It is installed outside b so that it can slide horizontally and vertically up and down. 4 is a horizontal cylinder, and the measuring head 3
can be slid in the horizontal direction, and when operated in the extending direction, the measuring tip 3 is positioned on the upper surface of the end of the plate-like object A placed on the guide section 2, and when operated in the contracting direction, the measuring tip 3 is returned to its original position. It is provided outside the vertical portion 3b of the measuring stylus 3 so that it can be returned to its original position. Reference numeral 5 denotes a vertical cylinder which can slide the measuring point 3 vertically up and down, and when operated in the extension direction positions the measuring point 3 vertically upward, and when operated in the contracting direction, the measuring point 3 is vertically positioned. The lower surface 3a can be stopped by coming into contact with the upper surface of the plate-like object A, and is attached to the lower side of the guide plate 2b. A sensor 7 is fixed to the side surface of the guide plate 2b below the detecting part 3c of the measuring stylus 3, detects the distance from the detecting part 3c, and changes the plate shape according to the amount of downward displacement of the measuring stylus 3. Detect the number of objects A. This means that, for example, when the distance between the sensor 7 and the detection part 3c of the probe 3 is the minimum distance within the detection interval, it is normal (0) and when the lower surface 3a of the probe 3 is in contact with one plate-shaped object A. 1 piece), the case where two plate-like objects A and the lower surface 3a come into contact is set in advance as two or more pieces, and in subsequent measurements, it may be determined based on which one corresponds.

を行なうことができる。Since the apparatus of the present invention is constructed as described above, the holder 1 is moved above the stacker in which the plate-like objects A that have been processed in the previous process are stacked and held, and the plate-like objects A are stacked and held. The plate-like object A is held between the claw parts 1a and 1b and moved onto the guide part 2, and is placed on the respective groove parts 2c of the guide plates 2a and 2b as shown in FIG. Then, the groove part 2c
By operating the vertical cylinder 5 in the extending direction toward the outside to move the measuring tip 3 placed at a predetermined height position, and by operating the horizontal cylinder 4 in the extending direction, the measuring tip 3 is moved over the plate-like object A. move it to Then, when the vertical cylinder 5 is operated in the direction of contraction, the horizontal lower surface 3a of the probe 3 comes close to the upper surface of the plate-like object A, comes into contact with it, and stops. Along with this, the detection section 3c of the probe 3 approaches the sensor 7. The sensor 7 detects the amount of displacement during this time. This amount of displacement is checked against a preset value, and if it is found to be a normal value and one sheet is detected, it is sent to the next process on the guide section 2 by a pusher, for example, and the holder 1 is transferred to the stacker for the next sheet. I went back to get item A. If it is determined that there are no sheets, the holder 1 returns to the stacker to pick up the next plate-like object A. Furthermore, if it is found that there are two or more sheets, the plate-like object A placed on the guide part 2 is gripped again with the holder 1, pulled up and moved, removed to a predetermined location outside the process, and replaced with a new one. Then move onto the stocker to hold the plate-like object A. By repeating this operation, it is possible to accurately feed one sheet at a time.

認められる。[Effects of the Invention] According to the present invention, the probe is lowered until it comes into contact with the plate-like object placed on the guide part, the amount of displacement during that time is detected by a sensor, and the amount of displacement of the plate-like object placed on the guide portion is detected by the sensor. Because it is designed to determine the number of sheets and take subsequent steps, it is possible to always accurately feed each sheet, which prevents defective items and equipment troubles in the next process. It has been recognized to be extremely effective in that it can accurately detect plates even if the material, shape, and weight of the plate-shaped object changes, and that it can automatically eject multiple sheets without the need for manpower or separate equipment. It will be done.
