Definitions

  • the present invention relates to a sheet punching and embossing machine according to the preamble of claim 1.
  • a sheet punching and embossing machine according to the preamble of claim 1.
  • Such a machine is in the WO 99/28118 A disclosed.
  • punching As punching the cutting is referred to as closed, geometric blank forms that can be circular, oval or polygonal as well as fantasy shapes of all kinds. Even the practices practiced in print finishing such as punching with punch, repel corners and register punching are counted to this area.
  • the punching takes place against a punching pad or against punches, in some cases it is also shearing operations (cf. Postpress, training manual for bookbinders, Bundesv Druck e. V. 1996, page 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. Since the end products are sophisticated packaging in terms of technical and graphic designs (such as packaging for cosmetics, cigarettes, pharmaceuticals, foodstuffs, etc.), special requirements are not only placed on the packaging materials themselves, but punching tools are also required for optimum results lowest tolerances and extremely precise and reliable working punching machines required.
  • the printed sheets stacked on a pallet are fed to the punching machine.
  • the singling of the sheets to be punched is first carried out in a separating device, which are then subsequently accurately aligned in an alignment device, taken over by a gripper carriage and positioned exactly in the punching device.
  • the gripper carriage can be moved by endless chains through the machine or driven by linear drives.
  • the punching device usually consists of a provided with a counter-plate resting table and provided with a punching and scoring tools via a lifting drive perpendicular to the counter plate up and down the movable table.
  • a drive for a sheet punching and embossing machine is from the DE 30 44 083 A1 known.
  • the machine described herein has a fixed undertable and an up and down movable top table for punching sheets of paper, cardboard and the like.
  • the movement of the up and down movable upper table is realized by rollers which are arranged on two eccentric shafts arranged above the table.
  • the upper table rests against the rollers on the eccentric shaft with spring force.
  • By a rotational movement of the eccentric shafts of the upper table is moved perpendicular to the lower table. Due to the eccentric drive results in the course of time, a substantially sinusoidal lifting movement of the upper table.
  • the crucible punch press has a first crucible, which is fixedly arranged in a machine frame, and a second crucible, which can be delivered against the first crucible, and which can be adjusted in the feed direction by means of four toggle levers acting on it in an articulated manner.
  • the knee levers are each supported via a support joint against the machine frame and are acted upon by a cam gear.
  • the object of the present invention is to provide a sheet punching and embossing machine having a plurality of processing stations whose stroke is independent of the conveying path of the sheet.
  • the deliverable tools are moved via separate drives. This makes it possible to control the separate drives separately. Via a position control loop, it is then possible to individually control the stroke movement of each tool.
  • the separate drives are hydraulic cylinders.
  • the piston In order not to move the pressure ports on the cylinders, the piston is attached to the moving part and the cylinder to the frame.
  • the deliverable tool can be moved via one or more hydraulic cylinders. With several cylinders, material irregularities or local material deficits can be compensated, especially if the hydraulic cylinders can be positioned freely on the deliverable crucible and, if necessary, they are designed differently. Even an individual position and pressure control can shorten the machine setup time when changing the order. It is possible to drive either the upper table or the lower table via the hydraulic cylinder.
  • the individual settings of the tools are determined as a function of a global machine angle, which is generated for example via a setpoint generator.
  • a resistance control can be used, in which the inflow into the cylinder is controlled by valves.
  • a displacement control is used for position control, which regulates the inflow into the cylinder via a variable displacement pump.
  • the hydraulic is dispensed with.
  • the lifting movement of the deliverable tool takes place in a known manner via eccentric drives or toggle lever drives.
  • the large power flow takes place from the press drive to the eccentric shafts; only a small part of the power has to run via a mechanical synchronization.
  • the synchronization is advantageously carried out via a connecting gear between the press drive and a king shaft.
  • the synchronization takes place via the drive motors controlled individually as servo drives. As a result, a simple synchronization is possible.
  • the transport device for transporting the sheets through the individual processing stations is designed as a linear drive.

  • 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 ,

  • the sheet to be processed 6 is transported by the conveyor 7, 8 in the conveying direction of the sheet F in the processing station 2, 2'.
  • the processing stations have an undeliverable upper table 10 and a subframe 9 fixed to the housing.
  • Four hydraulic cylinders 16 for applying the punching force to the punching tool are located in the machine base.
  • the hydraulic cylinders 16 are connected firstly to the upper table 10 and secondly in the machine housing of the sheet punching and embossing machine stored.
  • the hydraulic cylinders 16 cause a punching stroke h, by which the upper table 10 is moved against the fixed lower table 9.
