Definitions

  • the invention relates to a device according to the preamble of claim 1 for cutting a foam plastic body or the like.
  • Such a device is known from EP-OS 0 003 167 and US Pat. No. 4,222,299 belonging to the same patent family.
  • cutting wire tears and / or breaks of the end coil springs which tension the cutting wires can occur.
  • the known device is designed for changing all cutting wires.
  • the cutting wires are connected to the mounting bars via additional strips that can be detached from the mounting bars.
  • the additional strips with all cutting wires are therefore removed from the holding rods and other additional strips with cutting wires are fastened to the holding rods.
  • the invention has for its object to design the device of the type mentioned so that the change of all cutting wires can be carried out by a single person in a relatively short time.
  • the invention makes use of the knowledge that the desired goal can only be achieved if the supporting frame, which is a small or less rigid component, as a whole, i.e. including the support rods is interchangeable. To remove this support frame, only the pressure device has to be loosened, whereupon the support frame can be easily removed from the device.
  • the device is used to cut a foam plastic body 1, for example cuboid polystyrene foam plastic body into plates, with the aid of a cutting wire system.
  • This is cutting wire system, as shown in Fig. 1, to be stationary, in which case the foam is to be cut plastic body 1 in R I- processing of the arrow 2 moves.
  • the cutting wire system mounts the cutting wire system on a carriage which can be moved in the machine frame and to move along the fixed foam plastic body.
  • the cutting wire arrangement which is not shown in detail, can be designed in various ways, for example with only two counter-rotating support rods 3, as described in EP-OS 0 003 167 and US Pat. No. 4,222,299 belonging to the same patent family, or only two co-oscillating support rods 3 as in a priority peer patent application the registration - described rin, but also with four support rods, which at the same pairs and in opposite directions to oscillate, as described in DE-OS 28 05 625 and of the No. 4,018,116 belonging to the same patent family.
  • the cutting wire system in any case has a plurality of cutting wires 4 which are essentially parallel to one another and which are eccentrically fastened at their ends to at least two holding rods 3 which are arranged at a distance from one another and run parallel to one another and perpendicular to the cutting wires 4 and are assigned to two sets of cutting wire which oscillate in opposite directions are.
  • the support rods 3 are rotatably supported in the region of their ends in a support frame 5 encompassing the foam plastic body 1 and can be pivoted back and forth about their longitudinal axis with the aid of an oscillation drive 6 assigned to the lower ends of the support rods 3.
  • the oscillation drive 6 consists of an eccentric drive with a motor 7, a flywheel 8 and a connecting rod S which engages a holding rod 3.
  • the second holding rod 3 is coupled to the first holding rod 3 via an indicated synchronous connection 10. A corresponding procedure can be followed if further mounting rods 3 are present.
  • the supporting frame 5 With its upper end ⁇ m, the supporting frame 5 is pivotable about an axis 11 parallel to the cutting wires 4 in suspension recesses 12 of an auxiliary support structure 13 is suspended and held at its lower end by means of a releasable pressing device 14 against abutments 15 on the auxiliary support structure 13.
  • the free lower ends of the support rods 3 are connected to the oscillation drive 6 via radial plug-in couplings 16.
  • the support frame 5 is suspended with lateral pins 17 in the suspension recesses 12 and, like the auxiliary support structure 13, is designed as a U-frame with an upper cross member. A lower crossbeam is missing because there are other machine parts at the corresponding location, such as a conveyor belt for the foam plastic body 1.
  • the auxiliary support structure 13 is shown as part of the machine frame; however, as has already been indicated above, it could also be arranged on a carriage which can be moved in the machine frame.
  • the abutments 15 holding the support frame 5 in position consist of spherical cap recesses 18 on the auxiliary construction 13, into which correspondingly shaped spherical cap projections 19 on the support frame 5 engage when the pressing device 14 is actuated.
  • the power connections for the electrically heatable cutting wires 4 consist of carbon brushes, which are spring-loaded against the pressing device 14, for the mounting rods 3, which carbon brushes thus provide an automatic power connection when the pressing device 14 is actuated.
  • Fig. 1 reveals that the support frame 5 can be removed from the auxiliary support structure 13 after loosening the pressing device 14 with the aid of a lifting device 20, which can work with a support frame magazine.
  • a lifting device 20 which can work with a support frame magazine.
  • the pressing device 14 consists of two pneumatic cylinder piston assemblies assigned to the ends of the support frame 5.
  • the lifting device 20 can also consist of such a pneumatic cylinder piston arrangement.
  • Fig. 2 shows how the radial plug-in couplings 16 are designed; seen in the longitudinal direction of the support rods 3, they have trapezoidal coupling halves which taper in the pressing device.
