Definitions

  • the invention relates to a method for converting a cutting punch and a cutting plate having cutting machine for preferably three-sided trimming a sheet stack according to the preamble of claim 1.
  • Cutting machines for trimming three pages of a sheet stack which are referred to in the jargon as "three-knife automatic machines", have a fixed lower cutting plate and a movable up and down press ram for compressing the sheet stack during trimming.
  • Such a cutting machine is for example from the DE 101 24 068 A1 known, which discloses the features of the preamble of claim 1.
  • the press die and the insert are adapted to the respective sheet format.
  • the punch and the inserts correspond to the cutting blades. Therefore, with changing paper sizes of the punch and the cutting plate must be replaced to adapt to the respective to be trimmed sheet size.
  • the consequent conversion of the cutting machine is done manually so far. This not only requires time, above all experience and skill; because especially the usually formed from cardboard die of the ram must be glued in exact relative position to a usually made of hardwood format plate of the press ram under the format plate, because sticking the die under the plate format even with small deviations from the desired position damages the die and especially the cutting blade result.
  • the present invention seeks to provide a method for time-saving retooling of the cutting machine and in particular for accurate positioning of the press ram, preferably the die.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is provided to replace at least the press ram or parts of the press ram from a positioning device for positioning to be trimmed sheet stack under the press ram. It is so in a format change an at least partially automated conversion of the cutting machine possible.
  • the peculiarity of this at least partially automatic conversion of the cutting machine is that the already existing for positioning to pruning stack of sheets under the press ram existing positioning is used. Accordingly, at least partially automatic retooling of the cutting machine needs to be provided so far no additional means. By using the existing positioning only the control of the same is to be supplemented, so that the positioning is used not only for positioning to pruning sheet stack under the ram, but also for at least partial replacement of the ram in a format change of the cutting machine.
  • the press ram fastened to a press ram holder is automatically uncoupled from the press ram holder and preferably also another press ram is automatically coupled to the press ram holder. It leads the automatic uncoupling of the press ram from the press die holder and the likewise automatic coupling of the press ram to the press ram holder together with the replacement of at least one part of the press ram by the positioning device to a substantially fully automatic format change.
  • the press die of the cutting machine usually has a format plate holder, a format plate and a die.
  • the press ram is fastened under the press ram holder.
  • the format plate is fixed, while the die is arranged under the format plate, preferably releasably.
  • it is intended to automatically replace the format plate holder with the format plate, and preferably also the die, from the positioning device.
  • the format plate holder with the format plate and the die attached underneath can be exchanged automatically.
  • the entire press punch preferably the format plate holder, the format plate and the die
  • the positioning device for format change performs approximately the same movement as for removing trimmed sheet stacks.
  • the positioning device also removes the pressing punch, in particular the format plate holder, the format plate and the die, as a whole onto a removal conveyor, which also serves to remove trimmed stack of sheets.
  • the discharge conveyor can be used for automatic format change.
  • the format plate holder and the format plate on the one hand and the die on the other hand positioned separately under the press stack holder, then the format plate is first positioned by the positioning with the supporting format plate holder under the die holder and coupled thereto. Thereafter, a boot-up of the ram holder with the format plate holder attached thereto, including the format plate attached thereto, is required. In this way, space for also automatically positioning the die under the format plate is created.
  • the separately supplied matrix is also automatically connected to the format plate by the format plate coming to rest on the matrix by lowering the press ram. It is so the die in the intended relative position to the format plate with the same connectable. This is preferably done by gluing. As a result, a connection between the format plate and the die comes about in a simple manner when the format plate presses against the die by shutting down the press ram.
  • the cutting plate is replaced automatically. This is preferably done by means of the positioning device, which also serves to replace at least parts of the press ram.
  • the positioning device For automatic replacement of the cutting plate is initially provided to lift the cutting plate by a lifting device before it is moved away from the positioning under the ram or the die holder.
  • the positioning device also moves the cutting plate away in the same direction under the ram in which trimmed sheet stacks are removed.
  • the previously exchanged insert simplifies the positioning of a new ram under the ram holder, in particular the joining of the die to the format plate.
  • a precisely positioned by the positioning exactly supplied new insert is lowered by the lifting device again.
  • the precisely positioned in this way cutting plate is then automatically fixed by a clamping device in a receptacle for the insert.
  • a fully automatic replacement of the insert is possible.
  • the controller receives a signal that it must carry out further work cycles in order to automatically position the die under the format plate and automatically connect the die to the format plate, in particular to glue it.
  • the positioning device can be procedurally provided to determine with the positioning device whether the press ram has been properly coupled to the press die holder. For this purpose, the positioning is driven to a level which is smaller than the nominal size of the sheet stack to be cut. If the punch has not been coupled to the die holder, it is still on the insert and it comes in the process of positioning a collision between the Positioning device and the punch or the die. The control of the cutting machine then determines the exceeding of a predetermined maximum force for moving the positioning, which is an indication of the failure of the coupling of the press ram to the die holder.

  • the three-knife automatic machine 10 has three cutting blades 13 and 14, namely two parallel longitudinally in the feed direction of the sheet stack 11 extending cutting blade 13 and a transverse cutting blade 14. The thus each perpendicular to each other cutting blades 13 and 14 serve to three vertical edges of the sheet stack 11 to crop. A fourth side of the sheet pile 11, which later forms the spine remains untrimmed.
  • the base of the cutting plate 15 corresponds to the format to which the sheet pile 11 is to be cut by the three cutting blades 13 and 14, namely, only a minimum is greater.
  • the cutting plate 15 thereby serves as a counter surface for the cutting blades 13 and 14 by the cutting blades 13 and 14 drive against the cutting plate 15.
  • a punch 16 is used to hold the printing sheet stack 11 in three-sided trimming in the exact position and squeeze.
  • the up and down movable punch 16 presses from the top of the to be trimmed sheet stack 11 so that it is immovably fixed during trimming between the cutting plate 15 and the ram 16.
  • the Fig. 1 schematically shows the punch 16 and the cutting plate 15 of the three-knife automaton 10.
  • the punch 16 has a format plate holder 17, arranged underneath a format plate 18 usually hardwood and arranged underneath a die 19 made of cardboard usually.

  • the press die 16 can be coupled with its format plate holder 17 by an automatic coupling device, not shown, to the press temple holder 20 and can also be automatically uncoupled from the press die holder 20 for the format change.
  • the format plate 18 is bolted to the format plate holder 17.
  • the die 19 is from the format plate 18, if necessary solvable.
  • the die 19 is glued under the format plate 18 by means of a suitable releasable Bonding.
  • the bonding can be done by double-sided adhesive tape.
  • the die 19 rests on top of the sheet stack 11.
  • At least the die 19 is adapted to the format thereof with respect to the edges of the sheet stack 11 to be trimmed by the cutting blades 13 and 14. To close the corresponding edges of the die 19 approximately flush with the cutting plane of the cutting blades 13 and 14.
  • the cutting edges 13 and 14 facing edges of the die 19 may have a slight distance from the respective cutting blade 13, 14, so that between the respective edge of the cutting blade 13 and 14 and the corresponding edge of the die 19 remains a narrow gap.
  • the cutting plate 15 is dimensioned somewhat larger than the format of the printing sheet stack 11. The cutting plate 15 protrudes at least opposite to the edges to be trimmed of the sheet stack 11 laterally or laterally opposite the edges to be trimmed the sheet pile 11 before Fig. 1 ).
  • the cutting plate 15 is formed either of a softer material than the cutting blades 13 and 14, or it has in the opposite the printing sheet stack 11 laterally projecting areas on soft mating surfaces, which are formed for example by inserts of a soft material in the cutting plate 15.
  • the cutting blades 13, 14 come when trimming the printing sheet stack 11 with these soft mating surfaces of the cutting plate 13 into contact, so that the tips of the cutting blades 13, 14 are not damaged.
  • Positioning device 21 shown serves to move a ready from the feed 12 before the ram 16 held uncut printing sheet stack 10 under the ram 16 and there to position exactly, in particular to the cutting plate 15 and the die 19 to align.
  • the positioning device 21 also serves to move a trimmed printing sheet stack 11 under the press ram 11 and to push it onto a delivery belt 22 serving for removing the trimmed sheet stack 11.
  • the three-knife automatic machine 10 described above is suitable by an appropriate control, in particular of the drive for moving the die holder 20 and the positioning device 21, for automated format change, including at least the plunger 16, preferably also the cutting plate 15, are automatically exchanged for a ram 16th and optionally a cutting plate 15 for another format, so printing sheet stack 11 with another base.
  • At least the replacement of the ram 16, including uncoupling and the Wiederankuppelns to the die holder 20, according to the invention is automatic, in particular fully automatic. However, it is preferably provided to also automate the exchange of the cutting plate 15 against such for a different format.
  • the receptacle for the cutting plate 15 has a lifting device, whereby the recessed lying in the receptacle cutting plate for automated replacement can be raised.
  • an automatic coupling of the receptacle for the cutting plate 15 is then assigned, whereby the cutting plate 15 is automatically uncoupled from the recording and after replacement of the cutting plate 15 against a new automatically be coupled again.

From the lifting rails of a lifting device, not shown, the dissolved cutting plate 15 is now raised to the working plane of the positioning 21. Now, the dissolved and raised cutting plate 15 is positively engaged by the positioning device 21 and conveyed onto the delivery belt 22, from which the cutting plate 15 is removed manually. Thus, the expansion of all previous width and height format-dependent parts of the three-knife automatic machine 10 is completed. There are still change parts that affect the stack height. The replacement of the cutting plate 15 is not in every format change required.
  • the cutting plate 15 is slightly larger than the format of the printing sheet stack 11 to be trimmed, it protrudes from the three sides to be trimmed at least at the same time. Now, if the format with the next to be trimmed sheet pile 11 changes little, in particular becomes smaller, so that a sufficiently wide edge region of the cutting plate 15 protrudes laterally relative to the sheet pile 11, the replacement of the cutting plate in the format change is unnecessary.
  • a new cutting plate 15, a new format plate holder 17 attached thereto with format plate 18 and a die 19 are first placed manually on the delivery belt 22. This is done in the above order, ie with front new cutting plate 15.

  • the delivery belt 22 is then driven in the direction of the positioning device 21, specifically until the format plate 18, with the format plate holder 17 fastened thereon, bears against stops 23 of the positioning device 21.
  • the stops 23 of the positioning device 21 block the further transport of the format plate holder 17 and the format plate 18 in the direction of the die holder 20.
  • the drive of the delivery belt 23 is then stopped. From the positioning device 21, the format plate holder 17 and the format plate 18 are now moved under the die holder 20 and there placed and aligned exactly in the intended position.

Thus, without manual inputs, the control contains the required data on the thickness of the format plate 18 and / or die 19. Thus, after each individual changeover process, the exact thicknesses of the die 19 and the format plate 18 are known. Accordingly, the three-knife automatic machine 10 can be operated with a minimum distance between the press ram 16 and the respective sheet stack 11.
