Definitions

  • the invention relates to a sheet punching and embossing machine with transport system according to the preamble of claim 1.
  • punching As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the 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.
  • 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.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 known.
  • the two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designatedWhentrenn arthritis.
  • a punching machine in which sheets are moved by means of linearly driven grippers through the machine.
  • the grippers are guided on at least one side by holding elements, wherein the holding elements are arranged parallel to a movement path of the sheets.
  • the holding elements in turn are moved by a linear drive in and opposite to the transport direction.
  • Gripper and retaining element are coupled together.
  • the grippers are attached to gripper bars, which are transported back after their movement through the punching machine.
  • the linear drive of the holding elements can be formed either by a parallel to the path of movement of the sheets extending spindle or by an electromagnetic drive system.
  • a disadvantage of this machine is that during the return transport of the gripper bars no sheets can be processed, which limits the productivity of the machine.
  • a gripper device for sheet-processing machines emerges in which sheets of grippers of a gripper device driven by driven chains are transported intermittently from one processing station to the next.
  • the chains are doing in a chain track and the gripper device by means of rollers in an independent of the chain track guideway guided.
  • This construction makes it possible that in the processing stations of the sheet processing machine, for example in punching and breaking station, the sheet to be processed can be lowered and thus rests on the machining tool. By depositing the sheet, for example on the punching counter plate or the breakout frame, the quality of processing is increased.
  • a disadvantage of this gripper device is that an exact positioning of the gripper device in the processing stations is made difficult by the occurring chain elongation of the drive chains.
  • the DE 34 09 314 A1 shows a sheet delivery with separate chain and gripper carriage, wherein a respective gripper carriage is connected via a coupling with the chain.
  • the chain and gripper carriage track have significantly different track geometries. This structure contributes to the fact that the oscillation input occurring through the gripper carriage slowdown in the sheet depositing area and subsequent acceleration, which has a wear-promoting effect, can be minimized. Although such a bow arm increases the smoothness and the life, but does not contribute to a more precise positioning of the bow.
  • Object of the present invention is therefore to provide a sheet punching and embossing machine, which is characterized by exact positioning of the sheets in the processing stations and high production performance.
  • An inventive sheet punching and embossing machine is used to edit sheets of paper, cardboard and the like in a punching station and at least one other processing station.
  • the sheet punching and embossing machine has a circulating transport system for transporting the sheets through the machine, the transport system comprising gripper carriages.
  • a respective gripper carriage has two carriages and an intermediate gripper bar with grippers for gripping the bow.
  • the carriages of a gripper carriage are on two parallel transport paths, an operator-side and a drive-side transport path through the machine emotional.
  • the transport path pair is advantageously divided into several sections and each section is associated with its own gripper carriage drive.
  • each gripper carriage has a coupling element for connecting the gripper carriage with the respective gripper carriage drive. If a gripper carriage is located in a specific section, the gripper carriage can be coupled with the gripper carriage drive associated with the section. If a gripper carriage leaves a partial section, the gripper carriage is decoupled from the gripper carriage drive again.
  • each gripper carriage drive has a coupling element.
  • both gripper carriage and gripper carriage drive each have coupling elements.
  • a first partial section extends in the region of the stamping station and one further partial section in the region of the at least one further processing station.
  • each processing station is assigned its own gripper carriage drive.
  • the transport path of the sheet punching and embossing machine has at least two curved regions and one partial section each extends to a curved region of the transport path.
  • a gripper carriage drive can be used for the curved area, which is tuned to the curvature.
  • a partial section extends to the region of the return of the gripper carriage. In this area, no positioning of the gripper carriage are necessary, so that a structurally simple drive can be used.
  • the gripper carriage drives may advantageously be linear drives with traveling-field motor, driven driving pins, a driven wheel or a conventional chain drive.
  • An advantage of a linear drive is that by means of the linear drive of the gripper carriage can be accurately positioned. Therefore, linear drives are advantageously used in sections in the field of punching station and other processing stations.
  • An advantage of driven drive pins is that it is a structurally simple drive. Driven driving pins are therefore advantageously used in the area of the return of the gripper carriage.
  • An advantage of driven wheels is that these circular or part-circular deflection movements allow easy. Powered wheels are therefore advantageously used in the curved areas of the transport path.
  • a respective transport path is designed as a gripper carriage guide track and the sheet punching and embossing machine has at least one operator-side and one drive-side linear drive guide track in the region of the partial section which is assigned a linear drive as gripper carriage drive.
  • Gripper carriage and linear drive guideway have independent path geometries. This allows, for example, the lowering of a sheet in the processing station, so that the sheet rests on the respective processing tool.
  • 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, fed to the transport system 7 and gripped by gripper bars of a gripper carriage 8 grippers at its front edge and intermittently in the sheet transport direction B through the various stations 2, 3 and 4 of the punching and embossing machine 100th pulled.
  • the transport path of the gripper carriage 8 is indicated by a dot-dash line.
  • 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 provided with a counter plate to the punching knife.
  • the upper table 10 is mounted vertically movable back and forth.
  • a gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent Ausbrechstation 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 6 are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets 14 are moved away with the stacked sheets 6 from the field of punching and embossing machine 100 can.
  • the transport system 7 has a plurality of gripper carriages 8, so that a plurality of sheets 6 can be processed simultaneously in the various stations 2, 3 and 4.
  • the transport path of the transport system 7 is divided into several sections S1-S6.
  • the section S 1 extends to the area of the punching station 2, the section S2 extends to the area of the breaking station 3, the section S3 extends to the region of the boom 4, the section S4 extends to the region of deflection of the gripper carriage 8 after depositing the sheet 6, the sub-section S5 extends to the region of the return of the gripper carriage 8 and the section S6 extends to the area the deflection of the gripper carriage 8 before taking over the sheet 6 from the feed table sixteenth
  • Fig. 2 shows a section Fig. 1 in detail.
  • An arc 6 is transported in the sheet transport direction B in the sheet transport plane E coming from the right through the sheet punching and embossing machine 100.
  • Shown is a linear drive A1, which moves the sheet 6 in the region of the boom 4.
  • the linear drive A1 has a linearly driven carriage 18, which can be moved in and against the sheet transport direction B.
  • At the right end of the section S3 of the linearly driven carriage 18 is coupled to the gripper carriage 8.
  • the linearly driven carriage 18 is moved by means of a traveling field in the sheet transport direction B and thus guides the sheet 6 to the boom 4. There, the linearly driven carriage 18 is stopped and the sheet 6 is slowed down so that the sheet 6 can be stored exactly.
  • the linearly driven carriage 18 is further moved in the sheet transport direction B to the end of the section S3 and decoupled there from the gripper carriage 8. Subsequent to the decoupling, the linearly driven gripper carriage 8 moves back to the right end of the subsection S3 in order to take over a following gripper carriage 8 with a bend 6.
  • the decoupled from the linear actuator A1 gripper carriage 8 is passed to the left end of the section S3 to a wheel A3mit terminals for clamping the gripper carriage 8, which transports the gripper carriage 8 in the region of the deflection, the curved section S4.
  • the wheel with clamps A3 rotates clockwise.
  • the gripper carriage 8 After approximately half a rotation of the wheel with clamps A3, the gripper carriage 8 is transferred to the gripper carriage drive with drive pins A2 and transported along the section S5.
  • the driving pins of the gripper carriage drive A2 push the gripper carriage 8 on a gripper carriage transport path.
  • the gripper carriage drive with drive pins A2 can be configured, for example, as a circulating conveyor belt or as a circulating chain.

  • the gripper carriage 8 is moved along a gripper carriage guide track FG.
  • the gripper carriage guide rail FG has a lowering 20. This reduction 20 causes a gripper carriage lowering, so that the sheet 6 comes to rest on the lower table 9.
  • the linearly driven carriage 18 is in a rest position.
  • FIG. 4 an alternative embodiment of the sheet punching and embossing machine 100 according to the invention is shown schematically.
