Definitions

  • the present invention relates to a sheet punching and embossing machine according to the preamble of claim 1.
  • 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 stamp, in some cases it is also shearing operations (see further processing, training manual for bookbinders, Bundes said Druck eV 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 is usually made 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.
  • Hardened steel plates are placed at the contact surfaces between the rollers and the table, which absorb the pressure and frictional forces exerted by the rollers and pass them on to the upper table. These steel plates may be wedge-shaped and then used for pressure delivery by providing corresponding means to move the steel plates with respect to the point of support of the rollers in the direction of the wedge inclination.
  • the Dymatrix series of die-cutters manufactured and distributed by Heidelberger Druckmaschinen AG, has four oil pans mounted on the upper table. In these oil pans are two guide webs on each slide two wedge plates. The lower wedge plate is adjustable via an adjusting device.
  • the driven wedge plate moves under the upper Keikplatte. This reduces the distance between the upper table and the lower table, which leads to a higher punching pressure. If this arrangement is often used with increased punching pressure, this leads to a greater wear of the wedge plates, which then have to be replaced.
  • Object of the present invention is to provide an alternative device for adjusting the punching pressure, which is easy to use.
  • At least one eccentric tooth bushing is mounted on the eccentric shaft, which drives the deliverable crucible.
  • the deliverable crucible is driven by two eccentric shafts. At each end of the two eccentric shafts an eccentric tooth socket is mounted, by the rotation of the punching pressure can be changed in each case.
  • This embodiment allows a simple and quick installation. Due to the separately adjustable eccentric tooth bushings a simple zone direction is possible. The adjustment process is very simple and allows a quick setup of the machine during job changes. In addition, any oil leakage problems are eliminated at higher punching speeds. Due to the separately adjustable eccentric tooth bushings, it is also possible to avoid tilting effects of the upper table when punching small-sized sheets.
  • the eccentric tooth bushings are motor-driven via worm shafts. It is conceivable to drive each eccentric tooth bushing separately or in pairs.
  • Fig. 1 the basic structure of a sheet punching and embossing machine 100 for punching, breaking and depositing sheets of paper, cardboard and the like is shown.
  • 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 grabbed by grippers at its front edge and intermittently in sheet conveying direction F through the various stations 2, 3 and 4 of the punching and Embossing machine 100 pulled through.
  • the grippers are in this case attached to gripper bars 8 and these in turn to a transport system 7.
  • the punching station 2 consists of a lower table 9 and an upper table 10.
  • the lower table 9 is fixedly mounted in the machine frame and with an unspecified darg Congressen counter plate provided to the punching knives.
  • the upper table is vertically movable back and forth and is provided with the punching and Rillmessern.
  • the grippers on the gripper bars 8 transport 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. 2 an adjusting device according to the invention for driving a sheet punching and embossing machine is shown schematically.
  • the illustrated drive of the upper table is an eccentric, which has proven particularly useful for driving punching equipment.
  • the upper table is driven by two eccentric shafts 15, of which in Fig. 2 however, only one is shown.
  • the eccentric drive consists of an eccentric shaft 15, which is supported in a manner not shown about the axis 22 rotatably by the yoke, not shown.
  • the eccentric shaft 15 is driven by means of a spur gear, not shown.
  • At the ends of the eccentric shaft 15 sits each a roller bearing roller 16.
  • On the eccentric shaft 15 are further mounted at the ends of the eccentric bushes 18, of which in Fig. 2 only one is shown.
  • the eccentric tooth bushings are mounted on the eccentric shaft 15 via ball bearings 17.
  • the eccentric shaft 15 and thus the roller 16 is adjusted, which in turn to a Distance adjustment between upper table 10 and lower table 9 leads.
  • the punching pressure is thus set.
  • the worm shafts are rotatably mounted on the yoke.
