Definitions

  • the invention relates to a cutting device for resin mats that have been unwound from a roll and pulled off the film as a tape that is covered at least on one side with a film, according to the preamble of claim 1.
  • the resin mat parts cut with such a cutting device are used, in particular, for molding molded parts of fiber-reinforced plastics, and are usually stacked into packages which can be inserted into the press before being fed to the pressing process.
  • the present invention is therefore based on the object of improving a cutting device of the generic type in such a way that less energy is required for the cutting process without major expenditure on equipment.
  • the rodless pneumatic cylinder of the new cutting device can be actuated from both sides, a cut can be carried out in each direction of movement, and the tool does not have to be returned to the starting position after the cut has been made. Accordingly, the reciprocating cutting blade is designed to cut on both sides.
  • the work cycle sequence can be accelerated in that both changeover valves are each connected to a compressed air reservoir.
  • both changeover valves are each connected to a compressed air reservoir.
  • one of the compressed air stores can be charged while the other store is being discharged
  • the outlay on equipment is further reduced by the compressed air reservoir being formed by a correspondingly dimensioned connecting line between the changeover valves.
  • the compressed air storage can also be made volume-adjustable.
  • the cutting device essentially consists of a pneumatic cylinder 1, in which a piston slide 2 is movably guided, to which a cutting blade 3 is attached.
  • the two ends of the pneumatic cylinder 1 are each connected at the end to a changeover valve 5 or 6 designed as a 2/3 directional valve.
  • the changeover valves 5 and 6 are each connected via a line 9 to a compressed air reservoir 7, which is connected to a compressed air source 11 via a line 4, into which a charging valve 8 designed as a 2/2-way valve is connected.
  • the charging valve is advantageously designed as a metering valve that is controlled as a function of time or pressure.
  • the electromagnetically actuated changeover valves 5 and 6 are shown in the rest position and the piston slide 2 in its left end position in the illustration.
  • the left changeover valve 5 is now actuated, as a result of which the connection to the compressed air accumulator 7 is established and the piston slide 2 moves in the direction of the arrow 10 into its right end position. Since the right-hand changeover valve 6 is switched to ventilation during the cutting process, only a correspondingly reduced braking effect occurs due to the air compressed in the pneumatic cylinder 1.
  • the piston slide 2 comes in its right End position after consumption of the major part of the energy supplied to rest.
  • the changeover valve 5 is switched back to venting and the compressed air reservoir 7 is again charged with a pressure of about 6 bar via the charging valve 8, so that the cutting device is ready for the next cutting operation in the opposite direction by actuating the changeover valve 6.
  • the piston slide 2 Due to its low mass and the lack of back pressure due to the vented opposite side, the piston slide 2, which is pressurized with compressed air, already reaches a very high speed after a short distance, e.g. > 5 m / sec. Due to the cutting force to be applied, the falling drive pressure and the back pressure rising due to air build-up in front of the respective switching valve, the piston slide 2 only has to be braked with its kinetic energy and with its pneumatic drive force already reduced to about 1/6. The damping that sets itself in the pneumatic cylinder 1, the so-called end position damping, is completely sufficient for this.
  • the resin mat tape not shown, which is fed perpendicular to the plane of the drawing, is uncovered by peeling off the films covering both sides by peeling and during Cutting process by means of a pneumatically actuated, rail-like pair of jaws running in the cutting direction, on which the cutting blade 3 is moved as close as possible.
  • a contactless sensor designed as a light barrier is arranged in the area of the cutting blade 3. It consists of a luminescence diode and an assigned photo transistor or a photo diode. With this arrangement, not only can a check for knife break be carried out, but also the function and operational readiness of the cutting device can be continuously monitored.
  • the sensor can be coupled at the same time with a switching device for the feed device of the resin mat tape to be fed.
