Definitions

  • the invention relates to a device for punching band-shaped and arc-shaped material, in particular cardboard, with at least one contact area, in which stamped sheets are stacked are arranged, and a crucible area, in which by Interaction of a punching tool and a counter punching plate Stamping products, so-called benefits, by means of a punch drive be produced, the punching sheets driven by Gripper elements are transported through the punching device.
  • the gripper is also not in print verifiable prior art known a gripper system the one continuous, at least over two working positions, Gripper pliers running to the side of the path of movement of the punched sheets two punched sheets each recorded on the side and together for each transported to the next working position, then the gripper after storing the punched sheets back into the starting position returns.
  • This gripper is indirect via the punch drive driven, the rotating movement of the punch drive with a high mechanical effort in a translation movement must be implemented.
  • the object of the invention is now to create a new one To provide a gripper transport system for a punching device, which has a higher positioning accuracy and above also allows a flexible movement.
  • the main advantage of the device according to the invention is that the die cuts with a much larger Positioning accuracy also on several, one behind the other Working positions of the punching machine can be transported whereby by separating the drive of the gripper transport device from the punch drive additionally the energy losses or Total energy consumption of the device is reduced. It is also with Such a device according to the invention possible, a very to bring about flexible movement of the punching sheets, this being the case can also cause movement from one to the other Working position no longer has to be synchronized.
  • An embodiment of the device according to the invention is characterized in that the grippers to the side of the trajectory are arranged and guided parallel to the movement path, the gripper with the holding element in transport and The opposite direction are coupled in motion and the grippers Cutting sheets on a boundary running in the direction of movement to capture.
  • the grippers as transverse to the transport device arranged gripper bars are formed that only in Transport direction a movement coupling with on both sides Have trajectory arranged holding elements and that the gripper bars cut the punched sheets at a right angle to the transport direction Detect current limit.
  • the fundamental advantage that the individual grapple bars each through separate holding elements arranged in pairs are driven, however, depending on the drive system, for example flexible movement of each individual, through pairs of holding elements moving gripper bar is possible.
  • this can be done in that the Movement coupling / decoupling of holding elements and Gripper bars by raising / lowering the separate drive including holding elements.
  • the two aforementioned embodiments can for example, a drive for the holding elements from at least have a spindle running parallel to the movement path, the actuation of the gripper via a parallel to the spindle extending camshaft can take place.
  • This system is on advantageous way that even when transporting the Gripper bars through individual pairs of holding elements 100% forced guidance of all pairs of holding elements within the punching machine is possible.
  • the Drive for the holding elements also from at least one electromagnetic drive system are formed.
  • This electromagnetic drive system could for example one that serves as a carriageway for the holding elements Have mounting rail, the holding elements each with Electronic magnets are provided, which hold the holding elements from the Hold the mounting rail spaced apart and the holding elements each are driven by a leading magnetic field.
  • Such a thing System would have the added advantage that it would be possible for everyone single pair of holding elements including gripper bars too to control independently.
  • stamping sheets 11 for Cardboard example, processed. It can be seen in FIG. 1 that the stamping sheets 11 at the beginning of the punching device 10 a stack 12 can be arranged. Not by one in Fig. 1 shown, but recognizable in Figs. 2 and 4 conveyor 13, a punched sheet 11 is placed in a contact position 14 transported. In Fig. 1 the punching sheet is in the area of the system 14 11 captured by a gripper transport system, not shown, and along the dash-dotted line into a punching or crucible area 15 transported in a larger number from a punched sheet 11 of benefit 16 (cuts). From there the punched sheet 11 transported to the stripping station 17, in which the Edge sections are removed from the panel 16. After that takes place in the so-called depaneling station 18 (see FIG. 4) individual benefits 16.
  • Path of movement of the gripper transport system is a punching tool 19 arranged in a fixed position, which is referred to as a band steel cut, while underneath there is a one that can be moved in the machine frame Counter punch plate 20 is present.
  • a punching device 10 will now focus - starting with Fig. 2 - a gripper transport system 21 shown and described. 2 and 3, this is a along one Movement path b of the punching sheets 11 gripper pliers 22, which is arranged on a holding element 23 which on a Guide rod 24 is mounted and driven by a spindle 25.
  • the gripper tongs 22 overlap two working positions, namely the system 14 and the punching or Crucible area 15 extends.
  • the position of the Gripper pliers 22 represent the maximum position in the y direction the gripper tongs 22 move in the x-direction up to the marking A. can.
  • the gripper 22 is first on electrical, electronic, hydraulic, pneumatic or opened mechanically and then starting from the stack 12 over the conveyor device 13 a punched sheet 11 in the angling position 14 and thus into a precisely defined position in the gripper tongs 22 emotional. After this is done, the gripper 22 and closes the spindle 25 is driven by a motor M until the gripper transport system 21 in the x direction up to the marking A.
  • FIGS 4 to 6 Another embodiment of the punching device 10 is shown in FIGS 4 to 6 are shown. 4 are from right to left Stack 12, the transport device 13, the system 14, the punching or Crucible area 15, the stripping station 17 and the depaneling station 18 to recognize.
  • the punched sheets 11 are transported in this case Embodiment, however, via so-called gripper bars 26 which captured on both sides of the movement path b by holding elements 27 be motion-linked with a separate linear drive are.
  • the linear drive can be used as a spindle drive 28 (see FIG. 6) or as electromagnetic drive 29 (see FIG. 5).
  • the holding element 27 sits on one Guide rod 30 and a spindle 31 in the transport direction T of the punched sheets 11 and driven in the opposite direction.
  • the Holding element 27 has a recess 32 for one on the punching sheet side End region 33 of the gripper bar 26 (see FIG. 5).
  • the recess 32 is with a centering hole 34 for one at the free end region 33 arranged centering pin 35 (see. Fig. 5).
  • the gripper transport system 21 (see FIG. 4) now has the following Sequence of movements: Again a die cut 11 is removed from the stack 12 transported by means of the conveyor device 13 into the contact position 14. Before the transport, the lateral spindle drives 28 are lowered, so that the gripper bar arranged at the contact position 14 26 in a locking position, not shown Punching device 10 is located in which the individual gripper elements 36 be opened. The punched sheet 11 is thus in the transport Position 14 at the same time the open gripping elements 36 fed. Then the gripper elements 36 are closed and the Gripper bar 26 is caused by vertical movement of the spindle drives 28 raised on both sides.
  • the linear drive 28, 29 can also be raised to another one Way done.
  • the Recess 32 points downwards, so that by lowering the Linear drive 28, 29 and the associated holding elements 27 a movement coupling with the gripper bars 26 takes place.
  • each individual Gripper bars 26 separately by holding elements 27 on both sides, which a mounting rail 38 arranged movably in the transport direction T. are driven.
  • the holding element 27 sits on the T-shaped Support rail 38 (see FIG. 5), the legs 39 on both sides of the Holding element 27 is gripped at a distance.
  • Opposite of End faces 40 of an upper cross member 41 of the mounting rail 38 on the holding element 27 each guide magnet 42 is arranged. Below the upper cross member 41 are on both sides Holding element 28 arranged so-called support magnet 43.
  • the electromagnetic drive ultimately works according to the Principle of the so-called electromagnetic levitation.
  • the support magnet 43 applied a voltage generated by the Magnetic coils flowing a magnetic field, which is the Holding element 27 under the upper cross element 41 of the mounting rail 38 draws.
  • the current is switched off again, as soon as the movement begins.
  • the voltage is switched on again, as a result of which the holding element 27 is pulled again from below to the upper cross member 41.
  • the holding element 27 thus follows one leading magnetic field, by changing the Speed and the strength of this magnetic field Speed of the holding element 27 can be influenced. Consequently it is theoretically conceivable that individual holding element pairs 27 and thus also individual gripper bars 26 can be controlled separately can.
