Definitions

  • the present invention relates to a method for slicing food products, in which the weight and/or the contour of several food products is determined, then a row of portions is produced by simultaneously slicing the food products in several tracks, with the food slice groups produced from a food product each are deposited in a lane, and finally the row of portions is conveyed away when the groups of food slices have each reached the predetermined portion weight. Furthermore, the present invention relates to a food slicing system that includes a weight and/or contour detection device, in particular in the form of a scanner and/or scales, which is set up to separately detect the weight of several food products, and a slicing device that is set up is to slice several food products in parallel in several lanes with different feed rates.
  • a method for slicing food products in which first the weight and/or the contour of several food products is determined, and then a row of portions is produced by simultaneously slicing the food products in several lanes, with the food slice groups produced from a food product each be placed in a track. When the groups of food slices have each reached the predetermined portion weight, the row of portions is conveyed away.
  • at least one portion weight equalization row is generated in which the food slice groups have different weights in at least two lanes, the weight differences of the food slice groups in the portion weight equalization row being equalized.
  • a weight equalization is only carried out in one portion row, namely the portion weight equalization row.
  • the slicing of dissimilar food products in several lanes next to each other can be optimized, not only reducing the number of the aforementioned corrections, but also avoiding voids in the portion format, which would either have to be compensated for or would lead to empty packaging.
  • the invention it is possible to intelligently distribute the weights and number of slices when slicing several food products at the same time.
  • the method is particularly suitable for so-called multi-track Vario slicers, in which each track can be sliced with a separately controlled feed.
  • the invention can be used particularly advantageously in a 4-track Vario slicer, which has four tracks arranged in parallel.
  • any variations in the weight of the individual food products being sliced at the same time are placed in a portion row, which then forms the portion weight offset row. Then all other portion rows only have good portions that reach the specified portion weight with little give-away and do not have to be corrected.
  • the food products are in particular food bars, i.e. elongate food products which have an essentially constant outer contour along their length.
  • these are sausage, ham or cheese bars.
  • the multiple tracks are arranged in parallel.
  • the tracks include a section upstream of a cutting plane, in which the respective food product is fed to a cutting blade, and a section downstream of the cutting plane, in which the rows of portions produced are conveyed further.
  • the feed to the cutting plane can be regulated independently in each lane, so that the portion weight can be regulated independently for each lane.
  • the multiple food products are cut open either by one or by multiple cutting knives, in particular by one cutting knife per lane. In advantageous embodiments, however, only one cutting knife is provided for all tracks.
  • Determining the weight of the food product is made possible in particular by a scale arranged upstream of the cutting plane.
  • a scanner can also be provided, with which the contour of the food product and possibly the density distribution in the food product can be determined. The first can be done with a laser scanner, the second with an X-ray scanner. In the case of a food product with a homogeneous density distribution and without internal cavities, determining the course of the contour can be sufficient to determine the weight, so that it may even be possible to dispense with scales.
  • a row of portions is an arrangement of one portion or group of food slices per track, which are arranged essentially at the same conveying height, the conveying height defining the height at which the group of food slices or portion is located along the conveying direction of the track.
  • an additional balancing portion in some lanes may be part of the row of portions located upstream or downstream of the portion in that lane.
  • the groups of food slices are in particular a plurality of food slices arranged flush on top of one another, overlapping one another or next to one another. Groups of food slices that have reached the predetermined serving weight can be referred to as (complete) servings.
  • the food products to be sliced have a weight difference of at least 2%, in particular at least 3%.
  • the weight differences can often be compensated for in other ways, for example with a higher give-away.
  • each of the food slice groups has the same number of food slices.
  • This portion row can be referred to as a partial portion row. This allows the slicing process to start simultaneously in each lane when the food slice groups or partial portions are completed by the food product following in each lane, and non-lane-related pauses must be provided in order to equalize the number of food slices. With this, the efficiency of the slicing operation can be increased.
  • each of the groups of food slices can have essentially the same weight. This simplifies the completion of the groups of food slices or partial portions with the slices of the food product that follows in the lane, since no significant weight differences have to be compensated for. This facilitates the control of the slicing operation at the beginning of the subsequent food product.
  • the last row of portions produced in each lane is completed with slices of food from a subsequent food product, so that a complete portion that has the predetermined portion weight is produced in each lane. This enables a seamless transition of the slicing operation between subsequent food products.
  • the slicing of each food product is started at the same time, i.e. in particular the first slice of each food product in the parallel tracks is produced essentially at the same time, for example by the same knife passage.
  • the last row of servings which is usually incomplete, has partial servings, each having the same weight and number of slices. This makes it easy to supplement with slices of a subsequent product in normal cutting operation.
  • the portion weight equalization row is provided in the penultimate portion row produced from the food products sliced at the same time. This ensures that there are enough food slices in this row to compensate for the weight differences to fully balance. Furthermore, it is achieved in this way that a maximum number of portion rows with complete portions from a food product follow one another and are not interrupted by the portion weight balancing row. Efficient further processing, in particular packaging, of the successive complete portions in the respective lanes can thus take place.
  • the track-related mean value of the number of slices of all food slice groups is the predetermined number of portion slices. It can thus be ensured that after the balancing by shifting food slices for each portion in the portion weight balancing row the predetermined number of portion slices is reached.
  • the food slice groups in two lanes each have such a number of food slices that their mean value is the predetermined number of portion slices.
  • the other groups of food slices of the portion weight equalization series then in particular already have the predetermined number of portion slices, ie they already form complete portions.
  • portion weight balancing can be achieved, i.e., a row of portions can be created in which all portions have the specified number of slices and reach the specified portion weight.
  • portion weight equalization row is shifted between lanes so that each lane has a portion that meets the predetermined portion weight.
  • a balancing of the weight of several food products can thus be achieved efficiently by a few locally limited displacements of food slices.
  • All portions with a predetermined portion weight advantageously have the same number of food slices. In this way, uniform portions can be produced which can be packaged and marketed in a uniform manner.
  • the portions that reach the specified portion weight it is also possible for the portions that reach the specified portion weight to have a different number of food slices.
  • the relative offset between food slices of a shingled portion is then selected to be smaller if the number of food slices in the portion is larger, and vice versa, so that portions with an adapted size are produced.
  • a shingle is chosen to be shorter if there are more slices per portion.
  • with such unequal food products not only is a different number of slices per lane produced, but often also a different portion edge in the case of shingled portions.
  • portion parameters can also be varied or changed.
  • the arrangement of interleaver foils or the folding of slices can be changed within portions.
  • a separate balance portion is created in the portion weight balance row, which is subsequently used to complete at least one food slice group in at least one other lane in the portion weight balance row.
  • the number of slices in the compensating portion is selected or precalculated by a controller in such a way that the number of food slices in the compensating portion each have a common multiple, in particular corresponding to the number of lanes with underweight groups of food slices, in order to divide up the partial portion or redistribute it to these lanes to simplify.
  • the number of slices of compensating portions in the adjacent tracks is selected or calculated by the controller such that their number has a common multiple, in particular corresponding to the number of tracks. If the equalizing portion had a number of slices that exceeded the multiple, this excess would either be removed from the process, or remain on the uncut residual area or end piece of the food product, or be left as a give-away in at least one portion.
  • the equalizing portion is redistributed to three lanes in a four-lane slicing device, for example, there is an overhang of a maximum of two slices.
  • the excess weight of a food product in a lane can be distributed evenly over several groups of food slices in the portion weight balancing row by the at least one balancing portion, so that all food slice groups in the portion weight balancing row have the desired number of slices and the specified portion weight reach.
  • the predefined portion weight in its lane is increased, so that an even distribution of the excess weight is made possible. So the target weight is shifted slightly so as not to create too many overhang slices. The excess weight is thus evenly distributed over the portions, with a give-away being accepted in this track. It can thus be avoided that a second or further portion weight compensation row has to be provided, or that the stacks of slices to be shifted become too large for efficient handling.
  • the specified portion weight can be increased in all lanes. This means that if a food product is clearly too heavy in one lane, the excess weight can be evenly distributed over several portions in order to get back into the range of possible correction with the weight differences to be corrected. This means that the standard weights of the portions can also vary, and a small give-away is accepted in all lanes.
  • an enlarged tail may remain after the food product has been sliced, which is then removed from the slicing operation, e.g. discarded, sliced separately, or otherwise utilized.
  • the invention provides a food slicing system that includes a weight and/or contour detection device, in particular in the form of a scanner and/or scales, which is set up to separately detect the weight and/or the contour of a plurality of food products, and a slicing device , which is set up to slice several food products in parallel in several lanes with different feed rates.

  • a slicing device which is set up to slice several food products in parallel in several lanes with different feed rates.
  • a controller is provided which is set up to control the slicing device based on the weight and/or contour information of the food products, so that weight differences between the food products in at least one portion weight balancing row, with at least one underweight food slice group, be compensated for prior to slicing the upstream end of the respective food products such that the upstream end has substantially equal weight in all lanes.
  • the food products from all lanes can be guided through the weight and/or contour detection device in just one lane and only then be distributed to the multiple lanes of the slicing device.
  • weighing and scanning can be done in parallel lanes, either simultaneously for all lanes or staggered in just a subset of lanes.
  • a scanner and a scale can be provided in combination as a weight and/or contour detection device, in particular in one housing.
  • the food products can be weighed first and then scanned downstream, or vice versa, in which case different devices can be used which together form the system of the weight and/or contour detection device.
  • the controller is advantageously designed to control the slicing device in such a way that the upstream end of the respective food product is sliced into a partial portion that has the same number of food slices and/or the same weight in all lanes.
  • the partial portions can each be supplemented in an efficient and uniform manner by the subsequent food products to form a complete portion.
  • a format forming device is provided with a portion control display, which is designed to indicate to an operator how food slices must be relocated between the lanes in order to produce portions with the predetermined portion weight in the respective lanes.
  • the portion control display can be limited to one portion row, since only food slices are in the portion weight compensation row have to be relocated.
  • the portion control display can be provided as a display arranged next to the lanes, in which the number of food slices to be shifted per lane is indicated as a positive or negative numerical value. Alternatively, this information can be projected directly onto the groups of food slices in the portion weight balance row.

Furthermore, by limiting it to only one or a few rows of portions, the relocation movement can be displayed in such a clear and recognizable manner that errors can be avoided. Finally, the invention enables low give-away in all lanes.
  • the method according to the invention is preferably operated by a controller in the form of a microcontroller or process computer, the setup of which is determined by a corresponding program (software).
  • certain process steps, such as B. the relocation in the format formation device can be carried out by a human operator.
