Definitions

  • the invention relates to improvements and further developments in punching or embossing machines and sheet processing methods which can be carried out with such punching or embossing machines.
  • a punching or embossing machine is understood to mean a device for punching sheet-like material, in particular made of paper or cardboard, with at least one system station in which sheets to be processed are provided, a processing area in which a punching or embossing tool and a Counter-plate, the sheets to be processed are processed, and a delivery station in which processed sheets are deposited, the sheets being moved individually and step-by-step from the system station to the processing station by a sheet transport device, exposed in the processing station to the action of the punching or embossing tool and then from the processing station can be moved to the delivery station.
  • the DE 1 045 778 B discloses an automatic punching machine for sheet-like material, such as cardboard, paper or the like, in which the sheets are fed by means of gripper bars from the workstation where the sheets are punched out to at least one other location where the waste is broken out, the punching of the Materials effecting work station at least two detachably arranged one behind the other, designed as individual units in modular form, are connected downstream, the drive means for the ejectors are coupled to the drive means of the first work station.
  • sheet-like material such as cardboard, paper or the like
  • the generic EP 1 466 851 A2 describes in paragraph [0003] a known punching machine in which a continuous gripper, running at least over two working positions, to the side of the path of movement of the punched sheets, grasps two punched sheets laterally and transports them together to the next working position returns to the starting position. Because the gripper grips and holds both sheets at the same time, both sheets can only be deposited at the same time. With such an arrangement, a sheet that has already been processed can only be properly deposited in the delivery station if the sheets are deposited there on a stationary surface, for example stacked one on top of the other. This means that the sheets must then be removed from the delivery station one after the other, for example in order to break out copies cut from the sheet by punching and to separate them from the waste. This results in a considerable time delay.
  • the proposed method enables the two sheets to be deposited independently of one another, which enables the entire process sequence to be accelerated, in particular by providing a conveyor that operates continuously at a conveying speed in the delivery station for the further transport of a sheet onto which the processed sheet is deposited.
  • the already processed, ie punched and / or embossed sheets now no longer have to be accelerated again from standstill in the delivery station or removed separately from a stack in order to break out the benefits from the waste and separate from it, but the sheets can can be forwarded without interruption directly to a stripping station arranged in the sheet transport path to the delivery station, whereby the sheet is prevented from slipping on the conveyor by the fact that the sheet is deposited on the conveyor while in motion, whereby a significant increase in productivity can be achieved can.
  • the sheet to be processed and the processed sheet are moved at a transport speed that at least approximately corresponds to the conveying speed of the conveyor, at least when depositing, ie at the moment of depositing the processed sheet in the delivery station, than ever lower the relative speed between the conveyor and the processed sheet placed on it at the moment of The lower the tendency of the processed sheet to slip on the conveyor.
  • the risk of unwanted slipping of the sheet placed on the conveyor can be further reduced by holding the processed sheet on the conveyor by generating an air pressure difference between an upper side and a lower side of the sheet, for example by generating a negative pressure on the lower side of the sheet so that the sheet is pressed onto the conveyor by the surrounding air pressure.
  • the processed sheet is held on the conveyor by generating at least one force acting on an upper side of the sheet, for example by a hold-down device that is held above the conveyor at a distance that corresponds to the thickness of the sheet being transported corresponds to.
  • the proposed punching or embossing machine also takes into account the fact that the sheet to be processed must be deposited very precisely in the processing station, which is achieved by the sheet gripping device only releasing the sheet when it has come to a standstill at the second reversal point.
  • the already processed sheet removed from the processing station is already released by the sheet gripping device during the movement, which enables seamless further transport.
  • This further transport can be implemented, for example, by a second sheet gripping device which is arranged behind the processing station and which still holds the sheet takes over from this during the movement of the first sheet gripping device.
  • the sheet gripping device has at least two separately controllable gripping elements, so that one of the gripping elements releases the sheet to be processed after the sheet gripping device has come to a standstill in the processing station and the other gripping element releases the processed sheet before it reaches the second reversing position.
  • Gripping elements in this sense can be gripping tongs, suction grippers, etc., for example.
  • the sheet gripping device can have a common base rail with which the at least two gripping elements cooperate in order to grasp a sheet either jointly or independently of one another and then to deposit a sheet either jointly or independently of one another.
  • the upper rail which can be moved back and forth relative to the lower rail between a closed position in which the two arches are clamped, and an open position in which the two arches are released, could be divided into two partial rails which can be controlled separately in order to be able to individually grasp and / or let go of the respective bow.
  • the further transport of the processed sheet from the delivery station can be implemented, for example, by a second sheet gripping device arranged behind the processing station.
  • a conveyor operating continuously at a conveying speed is arranged in the delivery station for the further transport of a sheet.
  • Such a conveyor can for example be a roller conveyor which comprises a plurality of transport rollers arranged transversely to the transport direction, which are arranged one behind the other in a horizontal plane and whose top surface lines define a transport plane for the processed sheets.
  • it can be a belt or belt conveyor that has a flat conveyor belt or one or more relatively narrow conveyor belts that are guided around at least two deflection rollers or deflection rollers and whose upper runs each define the transport plane of the sheets.
  • the sheet gripping device moves between the first reversing position and the second reversing position at a transport speed which at least approximately corresponds to the conveying speed of the conveyor, at least when depositing, i.e. at the moment of depositing the processed sheet in the delivery station, as already mentioned above Reference to the proposed method was explained in more detail.
  • the conveyor is designed to generate a negative pressure on the underside of the sheet.
  • the conveyor is a belt conveyor with a perforated belt and a suction box arranged below it.
  • at least one pressure means acting on an upper side of the sheet for example one or more, can be located above the conveyor Pressure rollers, be arranged.
  • the at least two gripping elements are in operative connection with a jointly acting actuating device for gripping the respective sheet and with separately acting actuating devices for depositing the respective sheet.
  • the punching or embossing machine 1 shown comprises a discontinuously working system station 11, a discontinuously working processing station 12 and a continuously working delivery station 13. Laterally next to the system station 11, the processing station 12 and the delivery station 13 and thus parallel to a sheet transport path, along whose sheets 31, 32 are moved by the punching or embossing machine 1, extends a sheet transport device designed for gripping, moving and releasing two sheets 31, 32, which has a linear guide 24 and a linear guide arranged parallel to a sheet transport path the linear guide 24 between a first reversal position and a second reversal position back and forth movable sheet gripping device with a common base rail 23, which is the lower rail in the embodiment, and two separately controllable gripping elements 21, 22, which are part of the upper rail in the embodiment, which are connected to the common Base rail 23 cooperate in order to each grip a sheet 31, 32 on a lateral edge.
  • a sheet stack 4 is arranged in the area of the contact station 11, by means of which the sheets 31 to be processed are made available on the machine and fed individually to the contact station 11.
  • Fig. 1 the sheet gripping device is arranged in a first reversal position, in which a first gripping element 21 for gripping a sheet 31 to be processed in the contact station 11 and a second gripping element 22 for gripping a processed sheet 32 is positioned in the processing station 12. Both gripping elements 21, 22 are open and thus ready to grasp one sheet 31, 32 each.
  • Fig. 2 shows how a sheet 31 to be processed is removed from the sheet stack 4 and moved transversely to the sheet transport path in the plant station 11, while in the Processing station 12 an already processed, ie embossed or punched sheet 32 lies in such a way that it can be gripped by the second gripping element 22.
  • the sheet 31 to be processed has also come to a rest in the contact station 11 in such a way that it can be gripped by the first gripping element 21.
  • Fig. 4 shows how the first gripping element 21 grips the sheet 31 to be processed lying in the contact station 11 and the second gripping element 22 grips the processed sheet 32 lying in the processing station 12.
  • the gripping takes place simultaneously in that both gripping elements 21, 22 are closed simultaneously by a common actuating device, so that both sheets 31, 32 are gripped on a lateral edge, that is to say parallel to the sheet transport path.
  • Fig. 5 shows how the sheet gripping device with the closed gripping elements 21, 22 and both sheets 31, 32 is moved from the first reversing position in the direction of the second reversing position.
  • Fig. 6 it is shown how the second gripping element 22 is opened by a separate actuating device and deposits the processed sheet 32 on a continuous conveyor arranged in the delivery station 13, which conveyor moves at the same speed as the sheet gripping device, while the sheet gripping device approaches the second reversing position, ie before the second reversal position is reached. From this point on, only the sheet 31 to be processed is moved by the first gripping element 21 of the sheet gripping device, while the processed sheet 32 is moved by the continuous conveyor is moved on.
  • Fig. 7 shows the moment at which the sheet gripping device reaches the second reversing position and comes to a standstill there.
  • the first gripping element 21 deposits the sheet 31 to be processed in the processing station 12 in that the first gripping element 21 is opened by a separate actuating device. Both gripping elements 21, 22 are now open, and the processed sheet 32 is moved on by the continuous conveyor arranged in the delivery station 13.
  • Fig. 8 shows, the processed sheet 32 on the conveyor leaves the punching or embossing machine 1, for example to be fed to a stripping station, while the sheet gripping device with the two gripping elements 21, 22 is moved back into the first reversal position and the sheet 31 to be processed is in the processing station 12 processed, that is, embossed or punched. The steps described are then repeated again.
