Definitions

  • the present invention relates to an unwinding device with which an interleaver strip is unrolled from an interleaver roll.
  • the present invention also relates to a system consisting of a slicing device and the unwinding device.
  • Interleavers for example pieces of paper, are placed between two food slices, for example, in order to reduce their adhesion to one another and are from the prior art, for example the EP 1 940 685 B1 known.
  • This insert is generally made while a product is being sliced into a multiplicity of food slices, in that the interleaver is cut off from an interleaver strip, preferably essentially at the same time as the respective food slice.
  • the interleaver then falls together with the respective food slice, for example on a support table on which several food slices are configured to form one portion.
  • the slicing devices are mostly provided in multiple lanes, ie several products are cut open at least partially at the same time, so that an interleaver strip has to be made available for each lane.
  • an unwinding device that has a plurality of cassettes, in each of which an interleaver roller is rotatably mounted and the interleaver roller rotates when it is unrolled, the interleaver roller automatically braking in the event of a failure.
  • the present invention relates to an unwinding device for a plurality of interleaver rolls.
  • the unwinding device has a plurality of cassettes in which, preferably one, interleaver roller per cassette is rotatably mounted.
  • the interleaver roll rotates when the interleaver strip unrolls.
  • the tapes are preferably arranged parallel to one another on the unwinding device and can preferably be removed from this one at a time.
  • the unwinding device is preferably not part of the slicing device, but can be moved independently of it.
  • the unwinding device preferably has rollers or the like on which it can be moved towards and away from the slicing device.
  • Each cassette provides the interleaver strip for a track of the slicing device, in each of which a product, for example a sausage, cheese or ham bar, is sliced.
  • a product for example a sausage, cheese or ham bar
  • the slicing speed of the respective product in the respective lane can be the same or different.
  • either this roll or the respective cassette in which the used interleaver roll is located can be exchanged.
  • the entire unwinding device can also be exchanged as soon as at least one interleaver roll has been used up.
  • the respective cassette does not have a brake, but the interleaver roller brakes itself automatically as soon as there is no need for interleaver strips, for example when a product change takes place in the slicing device.
  • the interleaver roller is preferably braked by a corresponding friction pairing between the interleaver roller and the axle on which the interleaver roller is mounted. Surprisingly, the interleaver roller is consequently not mounted with as little friction as possible, but rather a certain amount of friction is desired.
  • the interleaver roller preferably has a cardboard core which rotates on a rigid axis, in particular an aluminum axis.
  • the interleaver roller is preferably driven as pulse-free as possible, i.e. driven as slowly as possible and with the lowest possible fluctuations and without peaks, so that the unwinding speed does not or only slightly exceeds the transport speed of the interleaver strip.

  • the torque of the brake is preferably a function of the weight of the roll, i.e. the further the consumption of the respective interleaver roll has progressed.

  • the slicing device has, for example, a rotating cutting knife which separates the food slices from the front end of the food bar.
  • the cutting knife interacts with what is known as a cutting edge, which acts as a counter knife and, together with the cutting knife, defines the so-called cutting plane.
  • An adjustable cutting gap is provided between the cutting knife and the cutting edge, which should be as small as possible in order to prevent the slices from being "chopped off". However, the cutting gap must be so large that contact between the cutting knife and the cutting edge is reliably prevented.
  • the cutting knife is arranged on a rotor.
  • This rotor is preferably a so-called empty cut rotor with which the cutting knife is axially spaced from the front end of the food bar or the cutting plane, for example by a finished food slice portion from the cutting area of the cutting knife to be transported away.
  • the cutting knife In the spaced-apart position, the cutting knife continues to rotate at an unchanged speed, but does not cut any food slices from the food bar. This movement of the cutting knife is referred to as a so-called "blank cut”.
  • the cutting knife is moved back into the cutting plane and the slicing device is continued.
  • the slicing device has several tracks, each of which has its own drive, which transports the product to be sliced in the direction of the cutting knife. With this advance, the thickness of the respective food slice to be cut is determined, which corresponds to the advance of the respective product between two cuts.

  • the food slices are stacked or shingled.
  • An interleaver for example a piece of paper, is arranged between two food slices and / or between the portion and a support in order to reduce the adhesion between the food slices and / or a packaging.
  • This interleaver is preferably cut from an interleaver strip by the same knife that cuts the food slices, which for this purpose is preferably shot intermittently into the cutting plane as soon as the knife is no longer in the area of the interleaver strip exit.

  • the slicing device preferably has a drive for the interleaver rollers which rotates them to unroll the interleaver strip.
  • the number of drive means is particularly preferably smaller than the number of interleaver rollers that have to be driven. Very particularly preferably, only one drive is provided for all interleaver rollers.
  • a coupling is preferably provided between the drive and the respective interleaver roller, which coupling can be selectively controlled and with which the respective interleaver roller can be optionally driven.

  • Yet another object of the present invention is a method for unrolling an interleaver roll with the system according to the invention, wherein a buffer is operated when the interleaver roll is unrolled so that it buffers the overrun of the roll when the demand stops.
  • a buffer which is provided downstream of the interleaver roller for the interleaver strip, is operated in such a way that it compensates for a difference between the unwinding speed and consumption of the interleaver strip, at the same time from having such a large residual buffer capacity that the after-run when consumption is stopped which only buffers the interleaver roller, which is only braked by friction.
