Definitions

  • the present invention relates to a device for the separation of the poses in a working machine of plate or sheet elements for the production of packaging.
  • the upper tool is constituted by a horizontal board or plate gridded with holes, each punch being provided with an upper face intended to be put elastically in pressure contact with the lower face of the board by the 'Intermediate of at least one quick-fixing element, a first end of which engages the punch and a second end with a hole in the board.
  • the upper tool is constituted by a horizontal board or plate gridded with holes, each punch being provided with an upper face intended to be put elastically in pressure contact with the lower face of the board by the 'Intermediate of at least one quick-fixing element, a first end of which engages the punch and a second end with a hole in the board.
  • the upper tool is constituted by a set of punches, and the lower tool by a matrix with openings, the movable upper punches forcing the poses through the openings in the lower matrix by causing the rupture of the various attachment points which connected either each of the poses between them, or the marginal poses to a peripheral waste of the leaf.
  • the separation tools must therefore be adapted to the shape and arrangement of the poses of each new series of sheets to be worked.
  • the punches are mounted, in registration with respect to the cutting lines of the press, on a base plate fixed to an upper mobile tool-carrying frame of the station separation station. Below and opposite each punch, there is a corresponding opening or mesh of the lower matrix made up of bars. Bars are arranged so as to overlap to form a grid or matrix whose meshes have approximately the dimensions of the poses to be separated.
  • the object of the present invention is therefore to produce a device for separating the blanks which, on the one hand, eliminates the drawbacks mentioned above and, on the other hand, allows a significant saving of time for the production of the upper matrix by using standard elements adaptable to the configuration of the installation (or cutting). Means must also be provided on the tool for easily mounting therein a punch specific to the front waste of the sheet.
  • the movable upper bone separation tool shown in Figure 1 comprises two rectangular wooden boards or plates 1, 2 flattened and centered horizontally against each other.
  • the function of the upper board 1 is to increase the rigidity of the bone tool and to mount the latter on a mobile frame 200 (see FIGS. 6 and 7) of the blanking station, while the lower board 2 is used to support punches P1, P2 of separation of the poses.
  • the two boards 1, 2, held together by gluing or other suitable means, can also be made of aluminum, synthetic material or other light materials.
  • the lower plate 2 is pierced, for example by laser, with a multitude of holes 20 crisscrossing its entire surface. Inside each hole 20 is driven a socket 21 of metal or plastic whose length is approximately equal to the thickness of the lower board 2. Each socket 21 is also provided with a stop shoulder 21a bearing on the upper face of the lower board 2.
  • the upper board 1 is also gridded with a large number of rectangular openings 10 aligned in both directions with the holes 20 of the lower board 2. The size of the openings 10 is such that each includes several (for example 49) holes 20 in the lower board 2.
  • the upper board 1 is also provided with holes 12 in correspondence with the other holes 20 in the lower board 2 not encompassed by an opening 10.
  • Figures 2 and 2D show how a first punch P1 of relatively small size is fixed against the underside of the bottom board 2.
  • the punch P1 is presented in the form of a slightly elongated rectangular block 5, open at the bottom and closed at the top.
  • Block 5 consists of four vertical plates 51-54, joined together at the ends by bonding and closed above by a fifth bonded plate 55.
  • the upper face of the connecting plate or closure 55 intended to come into contact with the lower board 2 is provided with a non-slip coating 56.
  • the lower edge of each plate 51-55, intended to come into contact with a pose, is covered with foam 67.
  • a rectangular block 6 for fixing the punch P1 to the lower board 2.
  • Two short cylindrical rods 69 are fixed in a corresponding hole in the block 6. These two rods 69 also pass through an elongated opening 69a of two opposite plates 52, 54 of the punch P1. The width of the two elongated openings 69a is also greater than the diameter of the rods 69.
  • the rods 69 have the function of preventing the block 6 and the punch P1 from being able to separate, while allowing their relative horizontal and vertical displacement necessary for the positioning of the punch P1.
  • the upper face of the fixing block 6 can come into contact with the lower face of the connection plate 55 of the punch P1 , said two faces each being provided with a non-slip coating 61, respectively 57.
  • the fixing block 6 is connected to the lower board 2 by means of two self-locking pins B. Thereafter, only one pin B will be described, it being understood that the other is identical to it.
  • the spindle B comprises, in known manner, a head 80, a hollow rod 81 at the end of which are radially projection two balls 82, and a sliding central rod 83, the pin B can only be unlocked by pressing on the central rod 83.
  • In the fixing block 6 is made a bore in which is fixed, by means of a washer 64e and a circlip 64c, a hollow socket 62.
  • the socket 62 is closed at the upper end by a first washer 63 held in place by a circlip 64a.
  • Each of the two washers 63, 65 is provided with an opening for letting the rod 81 of the spindle B pass, a shoulder 68 of its head 80 bearing against the second washer 65.
  • a compression spring 66 is interposed between the two washers 63, 65.
  • a cylindrical part of the head 80 can penetrate inside the socket 62.
  • the head 80 and the balls 82 prevent the pin B can escape from the socket 62, that is to say from the block 6.
  • the upper plate 55 is also provided with a rectangular opening 55a of relatively large dimension to allow the rod 81 to pass.
  • the upper board 1 is provided with auxiliary openings 12 situated opposite the holes 20 of the lower board 2 which are not located inside the large rectangular openings 10, of so that you can also install a pin B at these locations.
  • the punch P2 is identical in shape to that P1 in Figure 2, but of larger dimension.
  • the block 6 ' is, on the other hand, of smaller dimension and comprises a single pin B.
  • the punch P2 does not have an upper plate (like that 55 of the punch P1) but only the non-slip coating plate 56' provided orifices 56'a for the passage of the rod 81 of the spindle B.
  • Each block 6 ' is fixed to the punch P2 so as to allow a certain vertical and horizontal movement of one relative to the other.
  • the operation of the punch P2 is similar to that of P1.
  • a metal bar 9 intended for fixing two special punches 90 for the separation of the poses directly linked to the front waste.
  • Several screws 91 each passing through the bar 9 and the lower board 2 and engaging with a threaded sleeve 92 crimped in the upper board 1, are used to fix the bar 9 (see FIG. 1B) against the board lower 2.
  • Each special punch 90 is fixed to the lower board 2 by means of two vertical supports 93.
  • Each support 93 comprises a body 96, a rod 99 passing through the body 96, and a nut 95 engaged with an external thread corresponding to the body 96.
  • the rod 99 is surmounted by a head 94 bearing against the upper face of the bar 9.
  • the rod 99 also comprises a lower thread 97 in engagement with corresponding threads of the body 96 and of a socket 98 crimped in the special punch 90.
  • a pin 97a locks in rotation the body 96 on the rod 99.
  • first plate 14 On the upper face of the front edge of the upper board 1 is fixed a first plate 14 by means of two threaded bushings 15, a second plate 16 located on the other face of the board 1, and two screws 17.
  • the first plate 14 is used to center the upper tool Os on the movable frame 200 of the station separation station.
  • the upper tool Os described above can be used with almost all the lower tools with adjustable dimensions known to date, for example that described in patent CH-A-617886 mentioned above.
