Definitions

  • the present invention relates to a device for slicing food products, in particular a high-performance slicer, with a cutting knife attached to a knife holder, which moves in a cutting plane, in particular rotating and / or revolving, to form slices of at least to separate a product supplied to the cutting plane.
  • the cutting blade may be, for example, a planetary rotating circular knife.
  • a sickle or spiral knife may be provided which rotates about a rotation axis and has a spiral knife edge. Due to the knife edge moving in the cutting plane, slices are cut from a supplied food product, e.g. Meat, sausage or cheese, separated. The separated product slices fall on the side facing away from the supplied product from the cutting blade and can be fed to further processing.
  • the DE 10 2008 019 776 A1 discloses a cutting apparatus according to the preamble of claim 1, in which a counterweight for the cutting blade is arranged in the drive shaft of the blade or in the blade receptacle for facilitating a cutting blade change.
  • a counterweight for the cutting blade is arranged in the drive shaft of the blade or in the blade receptacle for facilitating a cutting blade change.
  • a device for slicing food products comprises a replacement cutting blade holder and a knife changing device which is adapted to replace the cutting blade automatically in the presence of a replacement criterion against a replacement cutting blade worn by the replacement blade holder replacement blade, and a control device, the is adapted to output to the blade changing device a signal as soon as the Aus monkriterium is present, wherein the blade changing device a two-armed pivot lever which is rotatable about an axis of rotation on a shaft, one of the shaft associated controllable electric drive, and handling tools, which sit at the ends of the pivot lever and are adapted to take in response to the signal, the cutting blade and the replacement cutting blade for the replacement of the blade holder and the holder and after pivoting of the pivot lever to 180 ° to fix it again.
  • a worn cutting blade can be removed from the machine, for example, to be fed to a re-sharpening process while providing a new or resharpened replacement cutting blade.
  • the cutting blade can also be a relatively narrow cutting edge or a cutting element on a carrier, wherein the carrier forms the blade holder or a part of the blade holder in such an embodiment, in particular the carrier is not replaced with.
  • the device comprises a holder with a plurality of blade receptacles, which is movable relative to a product feed of the device by means of the blade changing device such that either one of the cutting blades connected to the blade receptacles can be selectively transferred to a cutting position.
  • the holder can after Be rotatable type of tool turret and wear at its periphery a plurality of cutting blades.
  • the cutting blades which are not in the cutting position, can be removed at an appropriate time and replaced with new or sharpened cutting blades.
  • the holder including all provided there cutting blade could be replaced as soon as all cutting blades are worn.
  • the device may also comprise a buffer unit, wherein the blade changing device is adapted to supply the removed blade to the buffer unit and / or to remove the replacement blade of the or another buffer unit. An operator of the device can then remove the removed cutting blade from the buffer unit and insert newly deployed cutting blade in the buffer unit or use, which is much easier and safer to accomplish than handling directly to the driven blade holder.
  • the replacement criterion may in particular be based on a degree of wear or wear of the cutting blade. Worn cutting knives can be replaced automatically before the cutting performance declines noticeably. In principle, it is also possible to carry out an automatic knife change whenever a different type of knife is required due to a change in the nature of the products to be sliced.
  • the blade changing device can furthermore be designed to remove the replacement cutting blade from a cutting blade magazine accommodating a plurality of cutting blades.
  • the operation of the device can be made particularly efficient in this way, since an operator does not must provide a new cutting blade for each blade change. Rather, it is sufficient if the entire cutting blade magazine is re-equipped in relatively large time intervals.
  • the blade changing device may comprise at least one electric, pneumatic and / or hydraulic actuator in order to accomplish the automatic blade change quickly and reliably.
  • the blade changing device comprises at least one robot.
  • a robot can carry out all the activities required for a blade change and can be used very flexibly.
  • the invention also relates to a method for slicing food products by means of a device according to the invention, in which a cutting blade is moved in a cutting plane, in particular rotating and / or revolving, in order to separate slices from at least one product fed to the cutting plane.
  • the cutting blade is replaced automatically in the presence of a replacement criterion against a replacement blade.
  • the operator of the associated plant itself decides when the cutting blade is replaced.
  • the Aus grillkriterium consists in this case in a corresponding command of the operator, for example in the form of an operation of a switch.
  • the cutting blade is replaced with the replacement cutting blade when the degree of wear of the cutting blade reaches a predetermined value and / or when a predetermined state of wear is present.
  • the degree of wear or the state of wear can be continuously recorded, for example, by means of a sensor during the cutting operation. It is left to the respective application, whether reaching the degree of wear or wear condition is only displayed to the operator of the system or whether the device completely independently initiates a blade change, as soon as a corresponding degree of wear or wear condition is detected.
  • the cutting blade can be exchanged for the replacement cutting blade by removing the cutting blade from a blade receptacle and connecting a replacement cutting blade to the blade receptacle.
  • the exchanged cutting blade is fed to a buffer unit and / or the replacement cutting blade is removed from the or another buffer unit.
  • a high-performance slicer 10 includes a cutting blade 11 that defines a cutting plane S.
  • the cutting blade 11 is formed here as a disk-shaped sickle blade, which is attached to a blade holder 13.
  • the blade holder 13 driven in rotation with the cutting blade 11 in the cutting plane S.
  • the high-performance slicer 10 comprises a product feeder 19, on which there is a product loaf or product bar 21 to be sliced.
  • the product feed 19 could also be designed to feed a plurality of product bars 21 arranged next to one another in parallel.
  • the product bar 21 is delivered to the rotating cutting blade 11 along a product feed direction P pointing at right angles to the cutting plane S.
  • the cutting blade 11 cuts through the product bar 21 with a knife edge 26 and separates it from the product slices 25 (FIG. Fig. 2 ), wherein it cooperates with a cutting edge 27 forming the end of the product feed 19.
  • the separated product slices 25 fall on the product feed 19 facing away from the back of the knife on a product support 29 ( Fig. 2 ) and can be further promoted or further processed, in particular an automatic packaging system (not shown) supplied.
  • the high-performance slicer 10 comprises a blade changing device 30 and a replacement blade holder 31.
  • the replacement blade holder 31 is designed in principle similar to the blade holder 13, however, does not have a drive 15 and is preferably arranged to be outside the immediate danger area and easily accessible to an operator. She wears a new or sharpened, ie not worn replacement blade 41st
  • the blade changing device 30 comprises a two-armed pivoting lever 33 which is rotatable about a rotation axis D on a shaft 35.
  • the shaft 35 is associated with a controllable electric drive 37.
  • At the ends of the pivot lever 33 sit only schematically illustrated handling tools 39, 39 ', which are seen in the product feed direction P immediately before the cutting blade 11 and the replacement cutting blade 41.
  • a control device not shown, outputs a signal to the blade changing device 30 as soon as an exchange criterion exists, ie as soon as the operator of the high-performance slicer 10 actuates a corresponding switch or a sensor detects a critical degree of wear or a certain state of wear of the cutting blade 11.
  • the handling tools 39, 39 ' are now together with the cutting blades 11, 41 back into the in Fig. 1 shown basic position retracted and the pivot lever 33 is pivoted through an angle of 180 °. After this pivoting operation, the handling tools 39, 39 'again moved up to the blade holder 13 and the replacement blade holder 31 and attached thereto. After the handling tools 39, 39 'were finally moved back into the basic position, the cutting operation with the attached to the blade holder 13, not worn replacement cutting blade 41 can be resumed.
  • the worn cutting blade 11 can be replaced by the operator for a new or resharpened cutting blade. For this, it is not necessary for the operator to gain access to the dangerous cutting area on the driven blade holder 13.
  • the replacement cutting blade holder 31 thus forms a buffer unit for the blade changing device 30, which in principle could also be designed to accommodate a plurality of cutting blades.
  • the replacement of the cutting blade 11 is fast and avoiding operating errors in front of him, so that can be reduced by the blade changing device 30 on the one hand long downtime for the high-performance slicer 10 and on the other critical situations due to incorrectly mounted knives are avoided.
