Definitions

  • the invention relates to a cutting device for separating packs from a Strand.
  • thermoplastic cups take food preparations such as curd or other milk products, pudding, jam, drinks or the like on. The same applies, however, to flat cardboard cuts.
  • the cutting is usually done by a die cut with an upper knife and a lower knife. These knives have to be aligned extremely precisely with one another. Therefore a lot of effort is required. For each pattern you need special top knives and Lower knife. When changing over to a different pattern, these upper knives and lower knives must be used be set up exactly. For processing thermoplastic cups with a circular cross-section a diarrhea punch must be used.
  • the object of the invention is to simplify the cutting device and shorten the Setup times and work cycles.
  • This object is achieved according to the invention by designing the cutting device with a from below in the vertical direction between the packs retractable lower knives and with an upper roller solved that together with a discharge gripper for the separated packs parallel to Transport route can be moved under pressure on the lower knife.
  • the invention differs from the prior art in that only for the cut a lower knife adapted to the cup cross section or the cup section is required, the upper roller but is largely universally applicable.
  • the use of a top roller makes it possible to Bottom knife to provide very narrow edges on the edge of the thermoplastic cup, so that even round Cup easily held in the lower knife and can be picked up by a gripper.
  • a particularly simple guidance of the top roller is achieved in that the top roller and the discharge gripper is seated on a carriage moved by a drive belt.
  • each individual blank is ensured by the lower knife Contains chambers with a support edge for each individual cut.
  • a soft cut is achieved in that the top roller is designed as a squeeze roller.
  • the cutting conditions can also be varied such that the nip roller in Rings arranged side by side in the axial direction.
  • each ring is resiliently supported on a support ring in the radial direction
  • the wear resistance is increased in that the rings are made of steel.
  • An optimization of the cutting pressure is possible in that a shaft of the top roller in rails is supported and that the rails are adjustable on a tool holder.
  • top roller is designed as a knife roller is.
  • thermoplastic cups 1 described with a food preparation. Filled and with a lid film, not shown sealed thermoplastic cups 1 are on a transport route, not shown in detail moved in batches in the direction of transport 2. Those connected in a strand at the upper edge Thermoplastic cups 1 must be cut and separated in a cutting device 3.
  • the cutting device 3 comprises a lower knife 4, which is on a lifting table 5 or tool carrier is arranged.
  • a cutting plate 7 or contour plate with cutting edges sits on a head plate 6 8.
  • the lower knife 4 has chambers 9 with a bearing edge delimited by the cutting edges 8 10 to accommodate the thermoplastic cup 1. After the still connected in one strand Thermoplastic cup 1 are moved over the lowered bottom knife 4, the lifting table 5 moves the lower knife 4 high, so that a thermoplastic cup 1 is seated in each chamber 9.
  • the cutting device 3 also includes a discharge gripper 11 and a squeeze roller 12 a carriage moved by a drive belt 13.
  • the nip roller 12 is based on the position 12 'under pressure against the transport direction 2 moved over the lower knife.
  • the support edge 10 can be very narrow his; Cups with a circular cross section are also securely held on the support edge 10.
  • the drive belt 13 moves the carriage back and forth in cycles.
  • position 12 of the nip roller the cups are cut and are picked up by the discharge gripper 11, the lifting table 5 is lowered.
  • a batch 14 of the thermoplastic cups 1 is transferred to a packing station 15 brought and filed there.
  • thermoplastic cups 1 has been moved into the cutting device 3.
  • the lifting table 5 starts up.
  • the squeeze roller 12 cooperates with the lower knife 4, so that the sealed thermoplastic cup 1 in the lid area.
  • the cutting device 3 is essentially fixed, since the subsequent packaging sections can hardly be moved.
  • the heating station 25 and the deep-drawing station 26 Filling station 29 and the sealing station 30 adjustable in the transport direction, as indicated by the double arrows is specified. This allows the filling system to be optimally adjusted to the respective format.
  • FIG. 5 shows a squeeze roller 41, which consists of ring sections which are flexible in the radial direction exists, so that an individual adjustment to the axial extension of the cross roller 41 Material to be cut and the cutting geometry is possible.
  • a cylinder body 42 On a cylinder body 42 are support rings 43 made of an elastically resilient material such as polyurethane arranged.
  • the support rings 43 are each separated by spacer rings 44.
  • Each support ring 43 receives an outer ring 45 made of hard material such as steel.
  • Each ring 45 engages with a groove 46 in the inner surface via the associated support ring 43.
  • the arrangement described is on a shaft 49 held together between a stop 47 and a clamping ring 48.
  • Each ring 45 can individually adjust in the radial direction so that an adaptation to different cutting conditions and tolerance compensation is possible.
  • Fig. 6 shows an embodiment of the top roller as a knife roller 51, the manner of a roller punch interacts with the lower knife 5. This is an advantage in some applications.
  • the lower knife 5 sits on a tool carrier 52.
  • Spindles 53 which are guided by spindle nuts, are guided in the tool holder 52 in the vertical direction 54 are displaceable.
  • the drive of the spindle nuts 54 is not shown in detail.
  • the Spindle nuts 53 carry rails 55 in which rollers 56 run.
  • the rollers 56 carry the shaft 57 of the Knife roller 51.
  • the spindles 53 enable precise adjustment of the rails 55 and thus the Cutting pressure.
