Definitions

  • the invention relates to a sheet punching and embossing machine with adjustable punching or embossing pressure according to the preamble of claims 1, 7 or 10.
  • punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds.
  • practices practiced in print finishing such as punching with punch, corner punching and register punching are counted to this area.
  • the punching takes place against a punching pad or against stamp, in some cases it is also shearing operations (vg. Postpress, training manual for bookbinders, Bundesvious Druck e. V. 1996, p. 351 ff .).
  • Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually.
  • a punching station has two crucibles, also referred to as upper table and lower table.
  • One of the two tables is moved, the other fixed.
  • One table carries the punching tool with the punching knives, the other table the counter plate.
  • the moving table is movable back and forth perpendicular to the counterplate plane via a drive device. In the drive devices to distinguish between toggle drive and eccentric drive. If the upper table is the moving crucible, this is connected via a yoke to the machine frame.

  • Shims are located under the press beam, on which the toggle lever drive of a moving undertable is mounted.
  • the shims can be moved by electric / pneumatic or hydraulic motors, thereby changing the vertical position of the press beams, so that the toggle lever drive and thus the moving crucible. This changes the distance between the moving lower table and the fixed upper table and thus the punching force.
  • the DE OS 24 48 814 shows a device for parallelism adjustment of the movable crucible of a crucible press and for punch pressure regulation of a crucible press.
  • the moving pot is here driven by a push rod crankshaft device.
  • the device is mounted on a bearing with trapezoidal shaped wedges. The oblique side of one wedge slides on the sloping side of the other wedge, so that in this Movement, the overall height is reduced or increased depending on the direction of adjustment of the wedges.
  • the device is mounted on four bearings with wedges. To regulate the punching pressure all wedges must be moved simultaneously. Here, the distance between the two crucibles, and thus the punching force, changed.
  • punching force adjusting devices can only be adjusted globally, i. based on the entire surface of the crucible. Due to the design, however, an uneven punching force distribution over the surface of the crucible is present in all stamping and embossing machines according to the prior art.
  • the punching force is introduced via individual force introduction points and thus does not affect the entire crucible surface.
  • there is a deformation of upper and lower table which in turn results in an uneven punching pressure distribution over the surface of the crucible.
  • the uneven punching pressure in turn causes an unclean cutting of the cutting blade of the punching tool. In the prior art, this problem is solved by the punching blades are individually highlighted.
  • Object of the present invention is therefore to reduce the setup time and thus to increase the productivity of the sheet punching and embossing machine.
  • this has at least one punching station with adjustable punching or embossing.
  • a first crucible of the punching station is fixedly arranged in the machine position of the sheet punching and embossing machine, a second crucible is movable and deliverable against the first crucible.
  • a Device for regulating the punching and embossing pressure is connected to the first fixed crucible.
  • the device for regulating the punching or embossing pressure in about the same base area as the first crucible is located in a plane parallel to this and is attached to the fixed machine frame of the sheet punching and embossing machine.
  • the device for regulating the punching and embossing pressure causes a deformation of the first crucible and thus a delivery of the first crucible to the second crucible.
  • the device thus allows an adjustment of the parallelism of the two crucibles, an adjustment of the flatness of the first crucible and a regulation of the punching or embossing pressure.
  • the device for regulating the punching or embossing pressure has a plurality of actuator elements.
  • the actuator elements can be controlled individually.
  • the actuator elements are distributed over the entire device for regulating the punching or embossing pressure.
  • the distribution can be even or uneven.
  • the sheet punching and embossing machine has this at least one punching station with adjustable punching or embossing, a first fixedly arranged in a machine frame crucible and a second deliverable against the first crucible crucible, said second crucible with a device for Regulation of the punching or embossing pressure is connected.
  • the device has at least five actuator elements which are distributed over the surface of the device.
  • the actuator elements can be controlled individually.
  • the punching or embossing pressure during operation of the sheet punching and embossing machine can be regulated by the device for regulating the punching or embossing pressure.
  • the sheet punching and embossing machine has this at least one punching station with adjustable punching or embossing with a first primarily lower fixed in a machine frame arranged crucible and a second primarily deliverable against the first crucible crucible, which via a yoke with the Machine frame is connected, wherein in the vertical supports of the yoke is ever a device for regulating the punching or embossing pressure.
  • Each device has at least one actuator element, which can be controlled individually and whereby the punching or embossing pressure during operation of the sheet punching and embossing machine can be regulated.
  • actuator elements electric motors, which are connected via a transmission with a device for changing or adjusting the crucible, or piezo elements or hydraulic chambers used.
  • the device for regulating the stamping or embossing pressure can also be advantageously used for stroke cutoff.
  • a Hubabscnies is necessary to prevent application of the film on the embossing mold and their bonding.
  • the sheet punching and embossing machine has separate drives of the sheet transport system and the individual processing stations.
  • the drive of the sheet transport system can be designed in particular as a linear drive.

  • the punching and embossing machine 100 has a feeder 1, a punching station 2, a breaking station 3 and a boom 4, which are supported and enclosed by a common machine housing 5.
  • the sheets 6 are separated by a feeder 1 from a stack and fed via a feed table 16 of the sheet punching and embossing machine 100 and gripped by a transport system 7 grippers of a gripper carriage 8 at its front edge and intermittently in sheet conveying direction F through the various stations , 3 and 4 of the punching and embossing machine 100 pulled.
  • the punching station 2 consists of a lower table 9 and an upper table 10, which are spaced apart by the distance a.
  • the lower table 9 is fixedly mounted in the machine frame and provided with a counter plate to the punching knife.
  • the upper table 10 is supported vertically movable back and forth.
  • the lower table 9 is in connection with a Device for regulating the punching or embossing pressure 20. This is located between the lower table 9 and the fixed machine frame 5.
  • the gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent breaking station 3, which is equipped with breakout tools.
  • the breaking station 3 the unwanted pieces of waste are pushed out of the sheet 6 downwards with the aid of the stripping tools, whereby the waste pieces 11 fall into a container-like carriage 12 inserted below the station.
  • the boom 4 may also include a pallet 13 on which the individual sheets are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets can be moved away with the stacked sheets 14 from the field of punching and embossing machine 100.
  • FIG. 2a shows a detailed view of the punching station 2 of the sheet punching and embossing machine 100.
