Definitions

  • the present invention also relates to a method for cutting food into strips or cubes according to the preamble of claim 12.
  • Machines for cutting food into strips or cubes have long been known and for example in the literature EP 2 080 599 B1 described. Such machines are often designed as so-called "dice cutters" in which the food to be cut is inserted into an elongated insertion shaft that forms the feed area.
  • a feed device By means of a feed device, the material to be cut is then advanced through an exit cross-section of the feed area onto a cutting device, which usually consists of two movable knife gates arranged crosswise one behind the other, in which several gate knives are held parallel to one another.
  • the movable mounting of the knife gates on the holding frame of the cutting machine takes place via two slide rods, which are arranged with their longitudinal direction parallel to the gate knives.
  • the material to be cut is cut into slices on the first knife gate, seen in the feed direction, and then into strips with a preferably square cross-section by the second knife gate.
  • a cross-cutting knife rotating perpendicular to the feed direction of the material to be cut, short sections, often in cube form, are finally produced from the food cut into strips by the two knife gates.
  • the disadvantage of these cutting machines is that the maintenance or repair of the known cutting devices is complex. If, for example, it is necessary to grind the knives of the lower knife gate, the product stabilizer and the upper knife gate must first be dismantled before the lower knife gate can be removed. The lower knife frame must then be removed from the lower holding frame, the knife frame opened and the knives removed individually. After the removed knives have been sharpened, they are reassembled with the same steps in reverse order. Since the machine parts described above are heavy cast or steel parts, dismantling the double gate device is laborious. Replacing the double gate device with another double gate device with different product dimensions is also complex in the known cutting machines.
  • the aforementioned object is achieved according to the invention in that the upper holding frame of the upper frame is arranged between the lower holding frame of the lower frame and the lower knife frame of the lower frame.
  • the lower knife frame and the upper knife frame follow one another directly and a distance between the knives in the upper and lower knife frames measured in the feed direction is reduced compared to the distance in conventional devices.
  • This also reduces the area of the food that cannot be cut due to a structurally determined distance between a knife back of the knives of the lower knife frame and a cutting edge of the knives of the upper knife frame.
  • the cutting quality of the device according to the invention is significantly improved. It is also possible to dispense with additional components, such as stabilizers in the form of metal sheets, which are absolutely necessary in conventional devices to ensure a good cutting result.
  • Another advantage of the inventive arrangement of the upper holding frame between the lower holding frame and the lower knife frame is that the knife frames can be replaced more easily, since both knife frames can be removed from the device without also having to remove the associated holding frames.
  • the knife frames as such have a significantly lower weight than the Knife frame in combination with the associated holding frame, so that replacing the knife frame from the device according to the invention is more convenient due to the lower weight of the component.
  • a preferred embodiment of the invention provides that the distance measured in each case in the feed direction between the guide rods of the lower holding frame of the lower creel and the longitudinal struts of the lower knife frame of the lower creel is greater than 15 mm, preferably greater than 20 mm, and / or the, in each case measured in the feed direction,
  • the distance between the guide rods of the upper holding frame of the top frame and the longitudinal struts of the upper knife frame of the top frame is greater than 15 mm, preferably greater than 20 mm, so that sufficient space remains for the arrangement of the upper holding frame or the lower knife frame.
  • the upper and / or lower knife frame preferably has two longitudinal struts, two cross members running transversely to the longitudinal struts and a plurality of knives running parallel to the longitudinal struts, which are connected to the cross members in a force-transmitting manner, which can be achieved by changing an adjustable distance of the Cross members can be clamped to one another.
  • This structure is stable and ensures that the knives are tensioned enough to cut geometrically accurate during the cutting process. This structure also opens up the possibility of re-tensioning the knives.
  • the lower and / or upper holding frame has two guide rods running parallel to the knives, which interact with the guide device, two cross members running transversely to the guide rods, at least one transmission element for Coupling with the lower or upper gate drive and at least two, preferably four bearing blocks for connection to the lower or upper knife frame, in particular with their respective cross members.
  • a technically simple and reliable guidance of the holding frame is provided via the guide rods which interact with the guide device.
  • the lower and / or the upper guide device it can be advantageous if it has a guide frame with a passage cross-section which corresponds to an exit cross-section at one end of the insertion area, the guide frame being fixable on a machine frame in such a way that the passage cross-section with is aligned with the exit cross-section of the insertion area.
  • the Guide frame guide bores can be provided which are used for the movable mounting of the lower or upper holding frame, in particular of its respective guide rods.
  • the lower and the upper guide device together form a one-piece component, preferably a base frame, in which guide bores for both the lower holding frame of the lower frame and the upper holding frame of the upper frame, in particular their respective guide rods, available.
  • the merging of the two guide devices into one component results in increased rigidity.
  • the relative position of the two guide devices to one another is determined by the design as one component and the installation of the same as well as their functionality is optimized.
  • the gate device has a stabilization device, preferably a stabilization frame, which has a passage cross-section which corresponds to the exit cross-section of the insertion area and which with lower fingers in gaps between adjacent knives of the lower creel and with upper fingers in gaps between adjacent knives of the Top gate intervenes. Adjacent fingers are separated from one another by slits, the clearance of which is slightly greater than the thickness of the knives entering the respective slits.
  • the product to be cut is also effectively guided along the side surfaces of the fingers that are directed inward towards the product to be cut, whereby a high geometrical accuracy of the product is achieved.
  • a distance between a back of the knives of the lower knife frame and a cutting edge of the knives of the upper knife frame is less than 5 mm, preferably less than 3 mm, more preferably less than 2 mm .
  • the aforementioned distance indicates - viewed in the feed direction - a thickness in which the food is not cut in both knife directions. The smaller this distance, the better the cutting result.
  • the inventive arrangement of the two knife frames directly one behind the other, that is to say without the interposition of the associated holder frames makes it possible to obtain such a small distance in the first place. A distance of 0 mm would be optimal, this distance being more theoretical due to certain tolerances.
  • a distance between a cutting edge of the knives of the lower knife frame and the exit cross section of the insertion area is greater than 20 mm, preferably greater than 30 mm, more preferably greater than 40 mm.
  • the two holding frames fixed in the guide device are arranged within this distance. The aforementioned distance ensures that there is sufficient space for the arrangement of the lower holding frame below the lower knife frame.

  • the cutting device of the device according to the invention advantageously has a cutting device, which comprises a cutting shaft that can be driven in rotation and is mounted in a machine frame and a cutting knife (cross-cutting knife) that can be coupled to it in a rotationally fixed manner, which in the course of a rotary movement completely sweeps over an exit cross-section of the insertion area projected into a plane of the cutting knife.

  • the aforementioned object is achieved by the method step that the lower knife frame of the lower creel is removed from the device, while the upper holding frame of the upper creel remains in an assembled state on the device.
