Definitions

  • the invention relates to a sheet punching and embossing machine with circumferential gripper bridges according to the preamble of claim 1 and a method for sheet alignment according to claim 11.
  • 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.
  • the punching tool and punched riddle plate In order to achieve a high product quality of the punched sheets, it is necessary that the sheets and tools are precisely aligned with each other.
  • the punching tool and punched riddle plate In the punching station of a sheet punching and embossing machine, the punching tool and punched riddle plate must be brought to an exact position in the circumferential direction and lateral direction. It must also be ensured that both tools are directly perpendicular to the sheet transport direction without skewing. This reference position is called "first knife".
  • the tools In the subsequent processing stations, the tools must be adjusted relative to the position of the first knife, such. B. the stripping board in the breaker and therictrenngitter in therictrennstation. The tools must be set in their three degrees of freedom.
  • the tools in the subsequent processing stations must also be readjusted to bring them back into the correct position relative to the "first knife”.
  • the register describes the positional accuracy of the printed image at the cutting, creasing and breaking edges of the sheet. Differences will be made between circumferential registration, ie the positional accuracy in the machine direction and side registration, ie the positional accuracy transverse to the machine direction.
  • a disadvantage of the register-accurate alignment of the prior art is that due to the high set-up times, i. due to the high time required for the adjustment of the tools, the machine productivity is impaired.
  • the EP 1 371 588 B1 describes a sheet punching and embossing machine with attached to circulating transport chains gripper carriage, which are aligned by a positioning device, driven by a servo motor rotary actuator in the circumferential direction.
  • the pivot drive has two separately controllable stops, which allow an oblique orientation of the gripper carriage.
  • the position of the positioning device can be changed by means of servomotors and the gripper carriage can thus be aligned individually.
  • the object of the present invention is to overcome the disadvantages of the prior art and a method for sheet alignment and a Bogenstanz- and Embossing machine with gripper carriage to describe, which allow high machine productivity and high product quality.
  • An inventive sheet punching and embossing machine has at least one processing station.
  • the processing station can be a punching station, breaking station or depaneling station.
  • the sheet punching and embossing machine further has a sheet transport system and a machine control for controlling the sheet transport system and the processing stations.
  • the sheet transport system has revolving gripper carriages with gripper bridges. Attached to the gripper bars are grippers which grasp the sheets at a gripper edge and move from station to station through the machine, the gripper carriages stopping to process a respective sheet in the respective processing station.
  • Each gripper carriage has - viewed in the direction of sheet transport - right and left trolley, which are attached to a respective revolving chain.
  • the gripper bar of a respective gripper carriage is connected by means of spring elements with the carriage.
  • the spring elements are designed such that the gripper bar can be moved for further alignment of the sheets in the processing stations and / or for gripper bridge lowering in the processing stations.
  • the gripper bar of a gripper carriage has a contact surface, which can be brought into contact with an adjusting element located in a respective processing station. Alternatively, several adjustment elements can be located in one processing station.
  • the adjusting elements each have a drive.
  • the adjusting element can transmit forces in the sheet transport direction and against the sheet transport direction to the respective contact surface of a respective gripper bridge. As a result, the gripper bar is aligned in the circumferential direction.
  • the adjusting element can transmit forces in the vertical direction to the respective contact surface of a respective gripper bridge. As a result, the gripper bridge is lowered.
  • the power transmission from adjustment to contact surface is done by friction.
  • the adjusting element may advantageously be a pressure roller which rotates about its axis and can be lowered perpendicular to the axis.
  • the power transmission from the adjusting element to the contact surface takes place in a form-fitting manner.
  • the spring elements are designed as spring plates and sliding joints with coil springs. It is also advantageous if the coil springs have a progressive characteristic. This ensures that only a force must be applied for a small deflection of the sliding joint.
  • this machine has at least one sensor for determining the sheet position in each processing station.
  • the design of the sensors is at the discretion of the expert.
  • the sheet punching and embossing machine can advantageously have a measuring system for measuring the sheet position in front of the first processing station. This measuring system can provide necessary information for a page orientation of the sheet.
  • the drives of the adjusting elements and the sensors of a respective processing station are part of a respective control loop. Each processing station is assigned a control loop.
  • the measuring system located in front of the first processing station for measuring the sheet position can be integrated in the control circuit assigned to the first processing station.
  • the invention comprises a method for sheet alignment in processing stations of sheets of paper, cardboard and the like, which are transported with gripper carriage through a sheet processing machine.
  • the sheet processing machine is in particular a sheet punching and embossing machine.
  • the gripper carriages have grippers for gripping the sheets and are driven by chains and thus transport a respective sheet into a processing station. As soon as a sheet is in a processing station, the drive of the sheet transport system is stopped and an adjusting element is lowered so far that it is in contact with a contact surface of a gripper bar.
  • the actual position of the sheet is compared with its desired position.
  • systems known to the person skilled in the art for subject detection ie the detection of the sheet position, are used, for example sensors and cameras.
  • the gripper bars of a gripper carriage are aligned by force transmission from the driven adjusting element to the contact surface of the gripper bar in the circumferential direction, whereby the sheet is circumferentially directed.
  • the sopasserausraum ie the exact register alignment of the gripper carriage perpendicular to the sheet transport direction, can be done by an additional mechanical adjustment.
  • the necessary adjustment paths are determined either by further systems located in a respective processing station for the collection of b, eg sensors or by the system located in front of the first processing station. It is particularly advantageous if the gripper bridge lowering is subsequently triggered in the processing stations by force transmission from a driven adjusting element to a contact surface of the gripper bar.
  • the sheet processing follows in the next step, the sheet processing.
  • the actual sheet position can also be measured before each processing station.
  • 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, the sheet transport system 7, a transport system with circulating chains, fed and gripped by gripper carriage 8 with gripper bars 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 100 pulled through.
  • the gripper bars of a gripper carriage 8 are connected by means of spring elements with the carriage (each not shown).
  • a measuring system 40 for precise measurement of the position of the sheets 6.
  • 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 supported vertically movable back and forth.
  • 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 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.
  • sensors 30 which determine the exact position of a sheet 6 by detecting its edges.
  • the values determined by the sensors 30 are transmitted to the machine controller 15 for evaluation.
  • Fig. 2 shows an adjusting element, here a pinch roller 50, in contact with a gripper carriage 8.
  • the gripper carriage 8 consists of a gripper bridge 8.2 with grippers 8.1 and carriage 8.3. At the gripper bridge 8.2 gripper 8.1 are attached to take a sheet 6 can.
  • the gripper bridge 8.2 is provided with a friction plate 51. About this friction plate 51, the pinch roller 50 is in contact with the gripper bridge 8.2.
  • the gripper bridge 8.2 is about several carriages 8.3 with the chain 7.1 of the transport system 7 (in Fig. 2 not shown).
  • the carriage 8.3 are attached to the chain pin 7.2 of the chain 7.1.
  • the attachment of the gripper bridge 8.2 to the carriage 8.3 is done via spring elements 8.4. Two different types of spring elements 8.4 are used.
  • the position of the spring elements 8.4 is defined by two axes A1 and A2, wherein both axes are parallel to each other and at right angles to the sheet transport direction B.
  • the spring element 8.4, which is located on the axis A1, consists of a sliding joint 55 with two coil springs 54 and allows a Displacement of the gripper bridge 8.2 in the direction a and thereby enables the registration alignment in the circumferential direction.
  • the spring element 8.4, which is located in the axis A2, consists of a spring plate 53 with joints 52. The joints 52 allow a rotation of the spring plate 53 in the plane spanned by the axes A1 and A2 plane. Further, the spring plate 53 can be deflected perpendicular to this plane in the direction b by a bend. By this deflection of the spring plate 53 a gripper carriage lowering is possible.
  • the register alignment a in the circumferential direction and the gripper carriage lowering b are triggered by corresponding movements of the pressure roller 50. Due to the pairing of friction pinch roller 50 / friction plate 51 causes a rotation of the pinch roller 50 a displacement of the gripper bridge 8.2 in or against the sheet transport direction B. This shift is the register orientation a in the circumferential direction and is made possible by the combination of the spring elements 8.4. If the pressure roller 50 is lowered, this movement is transmitted via the friction plate 51 on the gripper bridge 8.2. The gripper carriage lowering b is made possible by the flexibility of the spring plate 53.

  • FIG. 3b shows the situation of a gripper bridge 8.2 in the register-aligned state.
  • the gripper bridge 8.2 has been moved by the register P relative to the chain 7.1 and the chain pin 7.2 against the sheet transport direction B.
  • the coil springs 54 are unequally stressed and the spring plate 53 is twisted.
