Definitions

  • the invention relates to a slicer, especially for cutting food, with a Machine housing, one mounted on the machine housing and circular knives driven by a knife drive unit, one for adjusting the slice thickness of the to be processed Cutting material perpendicular to the cutting plane of the Circular knife adjustable with an adjusting device Stop plate and one on the machine housing parallel to the Carriage slidably mounted to the cutting plane with a cutting material support, the stop plate made of a safety position in which the stop plate Cutting edge of the circular knife covers, in a cutting position is adjustable for cutting the material to be cut.
  • Slicers of this type require through appropriate protective measures cut injuries the operator during cutting and To prevent cleaning if possible. The handling should the machine remains simple and optimal Cutting conditions can be guaranteed.
  • a cutting machine is known from DE 44 29 628 A1, which has a locking device which pivots of the clippings slide from its working position only allows out into a cleaning position if at the same time the stop plate for the slice thickness adjustment to a value "below zero" (safety position) is set with the cutting edge of the circular knife covered by the front edge of the stop plate and so that it is protected against careless contact.
  • the one adjacent to the knife Sledge support for the material to be cut must be at least 2 to 3 mm apart to have this to touch the fixed Stop plate with the to and fro carriage or to avoid its cutting material support. This distance leads to deterioration of soft clippings Cut quality.
  • the invention has for its object an optimized Cutting material support with the smallest possible distance to Cutting plane of the circular knife over the entire stroke of the Can be reached without using the machine and worsen the safety aspects during cleaning.
  • the Distance of the material support perpendicular to the cutting plane by means of an adjusting device between a minimum distance and a further distance is adjustable, and that the adjustment device of the stop plate with the adjustment device is coupled so that when moving the stop plate in the safety position the distance the cutting material support to the cutting plane to the further distance and when the stop plate moves into one Cutting position the distance of the product support to Cutting plane is changed to the minimum distance.
  • a Adjustment movement of the stop plate with an adjustment movement the adjustment device for adjusting the distance between the product support and the cutting level or circular knife level is made so that it is ensured that when the stop plate is moved into the safety position the distance of the product support to the cutting plane is enlarged and so a collision with the sled Cutting material support that can be moved back and forth parallel to the cutting plane is excluded with the stop plate.
  • the distance between Cutting material support and cutting level back to the minimum distance reduced as soon as the stop plate from the Safety position disengages and the collision described above can no longer occur.
  • the product to be sliced is placed on the circular knife or its Cutting plane moved and in a second embodiment the material support remains in its position during the circular knife moves towards the cutting material support once the stop plate is out of the safety position disengages and is brought into a cutting position.
  • the minimum distance of the product support to the cutting plane is preferred in spite of the above Cutting position of the stop plate is essentially constant be.
  • the cutting material support is moved relative to the circular knife to the distance Magnifying perpendicular to the cutting plane is preferred the cutting material support together with the slide between a position with the minimum distance and one Position with the specified further distance using the Adjustment device can be moved back and forth.
  • This embodiment leaves simpler coupling mechanisms of the adjusting device and the adjusting device.
  • the adjustment device for the cutting material support one with respect to their Eccentrically pivotable longitudinal guide rail which includes the slide parallel to the cutting plane slidably mounted.
  • the eccentrically mounted guide rail can simultaneously an approach or a moving away of the product support together with the slide from the cutting plane in be accomplished in a simple manner.
  • the Guide rail in particular have a cylindrical shape, which are arranged eccentrically at both ends Pin is rotatably mounted in the machine housing.
  • the lever turns the eccentrically mounted guide rail and thus ensures movement of the slide including the cutting material support perpendicular to the Cutting plane.
  • the aforementioned driver can be part of a cam be designed to control the cutting position the stop plate is used. This can be provided be that the driver as a radially arranged groove, for example in the cam, is formed in which lever can be engaged. When the Adjustment device, the lever is then over the driver led to the position to be taken. The swivel movement the lever can be limited by a stop be.
  • the lever after release by the driver on the scope the cam disc.
  • the lever is preferred fit elastically biased against the circumference.
  • a particularly preferred geometry can then be assumed if the pivot axis of the guide rail and its central axis with a medium slice thickness setting the Stop plate in one to the cutting plane essentially parallel plane.
  • the guide rail is only between swings two defined positions back and forth, this geometry should, of course, essentially prevail every slice thickness setting of the stop plate.
  • the driver also has a fang on the circumference of the cam include.
  • the advantages that can be achieved with the invention are in particular in that the cutting conditions over the whole Slice thickness setting range through the minimum distance between the cutting plane of the circular knife and the product support are optimized. This particularly affects soft cuttings such as sausage, cheese, fish, cheap on the Cut quality. It is avoided that the material to be cut one-sided during the cutting process due to the cutting pressure bent downwards or into a gap between them that is too wide Cutting material support and circular knife retracted and that Knife is pushed sideways. This will make one unclean Avoid formation of corners on the cut slices. In addition, the more favorable cutting conditions Drive energy saved on circular knife.
  • the invention is universal on all vertical and Bevel cutting machines can be used.
  • the cutting material support and the lateral guidance of the material to be cut on the carriage can be any known Shapes such as L-shape, U-shape or V-shape can be used.
  • V-shape for the first time, because with this the known, at the state of Technology already mentioned, attached to the machine housing Cuttings support cannot be used because of the lower edge of the material to be cut depending on the diameter of the material to be cut Height is fixed.

  • one is parallel to the cutting plane 6 of the circular knife 3 extending stop plate 7 for adjusting the slice thickness relative to the knife or cutting plane using a slice thickness adjustment device 8 arranged.
  • the well-known Slice thickness adjustment device 8 can be in an extreme setting to a slice thickness "below zero" (for example approx. -0.5 to -2 mm) can be set (safety position).
  • the front edge of the stop plate covers 7 the cutting edge of the circular knife 3 in the front Cutting area 5 and together with the knife protection ring 4 protection against accidental contact over the entire circumference the circular knife 3.
  • a carriage 9 for receiving a not shown Material to be cut can be pushed back and forth along the circular knife 3, parallel to the knife or cutting plane.
  • the material to be sliced is lying on the carriage 9, rotating Circular knife 3 fed and abutting the stop plate 7 sliced.
  • the cutting plane 6 of the circular knife 3 can be inclined to the installation surface the cutting machine 1 at a certain angle be inclined to the vertical, as shown in Fig. 1 (Bevel cutter), or arranged perpendicular to the installation surface be (vertical cutter).
  • the carriage 9 is rigidly connected to a carriage foot 10 and can be attached to a sled base 10 Swivel axis 11 from its working position shown in Fig. 1 in a cleaning position indicated by dash-dotted lines 9 'can be pivoted away.
