Definitions

  • the invention relates to a three-knife trimmer according to the preamble of claim 1.
  • a triple cutter is one used in the bookbinding industry Cutting device, the three cutting knives, namely includes a front knife and two side knives.
  • One Such three-knife trimmers are used to feed books fed that are already tied to the back. The The job of the trimmer is to read the books the sides and on the front edge in one operation cut to the final desired format.
  • the drive of such a three-cutter includes one with constant speed, continuously running rotor Electric motor, e.g. B. a three-phase motor or DC motor with a flywheel, a common drive shaft, that with the electric motor via a controllable Clutch or clutch-brake combination can be connected is, as well as several uniformly or non-uniformly translating Gearboxes, all with the common drive shaft are mechanically coupled.
  • rotor Electric motor e.g. B. a three-phase motor or DC motor with a flywheel, a common drive shaft, that with the electric motor via a controllable Clutch or clutch-brake combination can be connected is, as well as several uniformly or non-uniformly translating Gearboxes, all with the common drive shaft are mechanically coupled.
  • the coupling of the movements and the speed of movement of the moving parts in the individual stations is due to the design of the drive fixed and not changeable. This makes the three-knife trimmer run only economically at maximum operating height, the economy increases as the amount of use decreases from.
  • the coupling elements claim a significant space within the machine body of the three-knife trimmer and their respective arrangement is constructive due to the position of the parts to be moved given to the individual stations. This allows other parts, such as B. suction and discharge devices not optimally designed for cutting waste.
  • the invention has for its object in a three-knife a precise, variable coupling of those to be moved Allow parts to meet the requirements for economical operation even with variable heights to create and the mechanical effort and Space required for the coupling elements in favor of an optimal one Possibility of arranging suction and discharge devices to reduce cutting waste.
  • the motors can be servo or stepper motors arrange each directly on the parts to be moved. Coupling elements that were previously required to the parts to be moved with the single drive shaft couple, are not necessary. By eliminating the coupling elements can suction and discharge devices for Cutting waste better at the place where the cutting waste is created arrange and design for effective removal.
  • the movements and the speed of movement parts to be moved can be varied by the control computer be controlled around an economical way of working to secure all operating conditions. Furthermore, between an exact synchronization of the parts to be moved possible, so that the movements optimally on each other can be coordinated.
  • the ram as well optionally also the feed station, the Transfer station and the boom with separate drives equipped, so there is also the possibility To optimize guidance and application of force to the press ram and otherwise the performance of the servo or Stepper motors individually to the power and power requirements to adapt the relevant parts to be moved. This is an economical manufacture and a economical operation possible.
  • the drives can be rotary servo or stepper motors with downstream uniform or non-uniform include gearboxes.
  • drives are linear Servo or stepper motors include.
  • the drive of the linearly moving movable Parts take place immediately, so that a gear for There is no need to convert a rotary movement into a linear movement can.
  • top dead center of the front knife and the two side knives the control computer depending on the amount of use of the Cuttings can be controlled so that the idle stroke is reduced becomes.
  • Another measure to reduce cycle times and Improving the cutting performance is that Start time of the work movements of the press ram, the Front knife and the side knife by the control computer depending on the previous work movements to control so that the breaks between successive Work movements are reduced.
  • the press ram is expediently used by the control computer with constant force throughout the cutting process acted upon. This characteristic also leads to one conventional three-knife trimmer to an improved one Cut quality. So far, the pressing has been over generates a crank drive with a balance spring, but what in the beginning and end phase of the cutting process only a lower pressure allowed, so that when cutting of a stack of sheets could slip. Due to the further development according to the invention, this quality weakness becomes now effectively eliminated.
  • the maximum power is preferably the servo or Measure the stepper motors for the knives just large enough that the sum of the maximum motor driving force and the inertia occurring during the cutting process Knives including the parts moving with them straight greater than the maximum force peaks that occur when Cutting process.
  • the suction device comprises for cutting waste one below a cutting table the cutting station arranged at the cutting station.
  • FIG. 1 and 2 A feed station shows individual stations of a three-cutter 10, a transfer station 12, a cutting station 14 and a delivery belt 16.
  • Bound books enter the feed station 10 Magazine 18. There the books are in the transfer station 12 individually below from the magazine 18 through on a revolving Conveyor chain 20 attached driver 22 removed and moved towards the cutting station 14. In front The books are reached by the cutting position a pendulum positioning device 24 is detected and in transferred the cutting position to a cutting table 26, while the carriers 22 of the conveyor chain 20 down dive away.
  • the final Format cropped books captured by outrigger and on the delivery belt 16 transported.
  • the cutting station 14 also includes a cutting table 26 a cutting plate 28 and cutting strips 30 and three Knives, namely two side knives 32, 34 and a front knife 36.
  • the side knives 32, 34 and the front knife 36 are each in a knife holder, the Side knife holder in turn on a side knife bar attached and guided.
  • Fixing device not shown, part of the Cutting station 14, which is used during the book stack to fix the cutting process on the cutting plate 28, so that the stack as a whole or individual pages don't slip.
  • Suction device for cutting waste with a shredder.
  • the two side knives 32, 34 on the one hand and the front knife 36 on the other hand by separate drives moves, the digital bidirectionally controlled servo motors 38; 40 with downstream non-uniformly translating Gear 42; 44 include.
  • the conveyor chain 20 and the oscillating positioning device 24 by separate Drives with digitally controlled servo motors 46; 48 moves.
  • the drive of the conveyor chain also includes a uniformly translating gear 50, during the Drive of the positioning device is non-uniform translating gear 52 includes.
  • the movements of the servomotors 38, 40, 46, 48 are replaced by a common one Control computer controlled and synchronized precisely.
