  In each of the product separation devices described in the above publications, the vibration member and the repulsion member or the top plate and the cover are arranged above and below the vibration region of the workpiece, and the workpiece is brought into contact with them to separate the products. To do. Such a configuration is effective for quick separation and noise prevention, and is also useful for preventing product scattering. However, on the other hand, it is necessary to visually confirm the separation of the product. Therefore, it is necessary to provide an inspection window or the like above the apparatus.

  In the first place, there are a wide variety of plate products produced by general-purpose machines such as laser processing machines and turret punch press machines, and the thickness, material, and product imposition of the workpiece are not uniform. Therefore, if it can be confirmed that all the products have been separated from the workpiece, it can be said that a process design that can quickly collect the products and transport them to the next process is preferable.

  The present invention has been made from such a viewpoint, and the object of the present invention is to easily confirm that the product has been separated from the workpiece, and to quickly separate the product from a wide variety of workpieces. It is to provide a product / scrap separation device.

  According to one aspect of the present invention for providing means for solving the above-described problem, a work placing means for horizontally placing a plurality of impact protection plates at predetermined intervals to place a work, and the impact protection A step of separating the product connected by the micro joint from the workpiece, comprising a striking means for pushing up the plates at predetermined time intervals, and a product collecting means for collecting the product falling from the gap between the striking protection plates. A product / scrap separator that automates the process is provided. When the impact protection plate is pushed up at a predetermined time interval, the micro joint of the work placed on the impact protection plate is broken, and only the product portion falls from the gap between the impact protection plates.

  According to the present invention, the product / scrap can be quickly separated from a wide variety of workpieces without scattering or damage of the product, and it is easy to confirm that the product is separated from the workpiece, The product can be quickly collected and transported to the next process. The reason for this is that the upper part of the product / scrap separating apparatus has an open structure, and a configuration capable of efficiently causing metal fatigue in the micro joint.

And an axially extending rotary striking element arranged so as to push up. When the shaft is rotated, the workpiece is hit through a mounting plate on which the rotary hitting element is directly above. The mounting plate protects the product from being pushed up by the rotary striking element of the rotating shaft, and quickly removes the product separated from the workpiece from the vibration region by the opening.

  It is also preferable to provide means for adjusting the output rotation speed of the drive motor. By doing in this way, it becomes possible to give the impact and vibration according to a workpiece | work specification.

  Moreover, it is preferable that the rotary impact element of the shaft has an impact flat surface extending in the axial direction. By rotating the shaft on which the rotary striking element having such a striking flat surface is rotated, striking is performed uniformly on the surface, and the vertical movement of the mounting plate having an acceleration suitable for product separation occurs. It is possible to dampen.

  Moreover, it is also preferable to comprise in the column shape which has the cross-section of each rhombus shape of each shaft which has the said rotation impact element. According to the rotation of each shaft, a configuration is realized in which the large diamond-shaped large-diameter portion (the portion corresponding to the long diagonal line portion) pushes the upper workpiece placing plate at a predetermined time interval, for example, each shaft By arranging so that the long diagonal line of the substantially rhombus shape and the short diagonal line face each other, a configuration in which adjacent areas of the mounting plate are alternately pushed up is realized.

Referring to FIGS. 1 and 2, in the product / scrap separating apparatus, a plurality of shafts 2 and a mounting plate 4 that are pivotally supported by a plurality of pairs of bearings 3 are arranged in the upper structure of the frame 1. The lower structure of the frame 1 is provided with a drive motor 5 for rotating each shaft 2 and product collection trays 6 and 7 for collecting products falling from the opening 42 of the mounting plate 4. . The shaft 2 is provided with a rotary striking element 21 that is welded in pairs so that the flat surface abuts in parallel with the push-up region of the mounting plate 4, and the cross section thereof is as shown in FIG. 5. Further, it is formed so as to form a substantially rhombus having an acute angle. In addition, one end of the mounting plate 4 in the longitudinal direction is sandwiched by the clamp 44, and the other end is in a free state. Further, the product collection tray 6 is provided with a hinge (not shown) on the back side of the apparatus. By tilting the front side of the product collection tray 6 downward through the hinge, the product can be accumulated in the product collection tray 7. It has become.
