Definitions

  • the invention relates to a method and a device, in particular a high-performance slicer, for the simultaneous slicing of several food products.
  • This distance can be established by moving the product away from the knife during the blanking phase, or by being the knife that is moved away from the front end of the product.
  • EP 0 713 753 A2 such as WO 2010/011237 A1 directed.
  • the blanks are simultaneously performed on all tracks, ie for all food products, by either moving the common cutting blade away or moving the products together.
  • This prior art also contains nothing that could be understood as a reason or a hint to refrain from a simultaneous implementation of blanks on all tracks.
  • the generative DE 100 54 514 A1 discloses a device for slicing food products with at least two cutting blades, in which during the cutting time of a cutting head, the supply of another cutting head can be loaded.
  • the object of the invention is to provide a method and an apparatus for simultaneously cutting several food products, with or with the most versatile work possible.
  • the inventors have recognized that applications associated with simultaneously slicing several food products with surprising advantages are possible if the slices are not performed simultaneously on all tracks but on a track-by-track basis.
  • the device according to the invention is accordingly able to interrupt the feeding movement for each track independently of the other tracks and in particular to resume them.
  • the slicing device according to the invention comprises a correspondingly designed product feed and a control device which is designed for a track-specific blank cut management.
  • a track in which at least temporarily blank sections are performed or in which at least temporarily the supply of the product is interrupted also referred to as a passive track

  • the products are cut into portions which in each case comprise at least one product slice.
  • the invention is particularly advantageous in connection with such a portioned slicing of food products.
  • the products are supplied individually to the cutting blade as a function of information concerning at least the outer contour and / or the interior of the products.
  • the product feed can be designed to supply the products individually to the cutting knife as a function of information concerning at least the outer contour and / or the interior of the products.
  • information refers to information that at least includes information concerning the outer contour and / or the inner structure, ie the product interior, of the product.
  • the invention thus enables a track individualization taking into account information relating to the product interior and / or the product contour, for example the density distribution.
  • the product feed in the individual tracks therefore need not be limited to the outer product contour, that is to say the cross-sectional profile or the cross-sectional profile of the products, although this is possible according to the invention.
  • a maximum of such information can thus be used for the individual product supply. which are conducive to a weight-accurate slicing of the products.
  • the product feed takes place independently of information concerning products, in particular the interior of the products, in the other lanes.
  • information relating to the product interior With regard to the use of information relating to the product interior, a complete independence of the individual tracks from each other can thus be realized in the individual product supply.
  • the information in question here can be obtained on or in the slicing device, in particular on or in a product feed of the slicing device. It is therefore possible to integrate the means, which are also referred to below simply as product scanners, for obtaining the information relating to the product interior and / or the product contour into the slicing apparatus or the product feed. In principle, however, it is also possible to carry out the information acquisition at a location separate from the slicing device and / or independently of time from the slicing process. It is then necessary to provide appropriate means to allow the product to be related to the information obtained from the product in order to ensure that the correct information is taken into account in the individual product supply during the slicing of the products.
  • the information is obtained by a non-contact method, in particular using electromagnetic radiation.
  • the information can be obtained by screening and / or radiating the products. It is preferred if the information is obtained using X-radiation.

  • the or each product scanner may thus be configured such that each product is sequentially scanned at a plurality of individual levels.
  • the x-ray scanner may be stationary and arranged such that the scanning plane is perpendicular to the product feed direction, so that the information is obtained in such a way that the product in question is moved through the scanning plane during the scanning process.
  • the partial information obtained in the individual levels can then be assembled by means of a suitable evaluation device into an "overall picture" relating to the product interior.
  • the information can be obtained while the products are being fed to the cutting blade.
  • the individual product feed can be made such that the speeds at which the products are supplied to the cutting blade, adjusted individually and / or changed.
  • the products in the tracks can be fed to the cutting blade completely independently of each other.
  • the products in the tracks are fed to the cutting blade in such a way that a plurality of parallel next to each other arranged conveyors driven together and the individual speeds of the conveyors are changed individually.
  • the product supply takes place in each lane by means of its own control loop.
  • a perfect track independence can be achieved, at least with regard to the product feed and the taking into account of the information relating to the product interior and / or the product contour.
  • the means for obtaining the information are adapted to screen the products and / or to irradiate.
  • the means comprise at least one X-ray device.
  • a single product scanner can be provided for all tracks and thus all products to be sliced simultaneously.
  • each track may have its own product scanner. Even with the use of a single, common product scanner, information can be obtained and used individually for the individual products and, in particular, for the supply of the products during slicing.
  • the device is in particular designed to be operated according to a method of the type described here.
  • a plurality of product slices also referred to here as a portion, should not only have a predetermined weight and be presented in an appealing manner, but also It is also increasingly desired that the packages contain slices of different products or products of different types, for example of different types of sausage or different cheeses, where it is also desired, for example, to form a mixed total portion in the packs of sausage and cheese slices.
  • each portion fulfills a condition prescribed for the respective track, in particular the weight of the portion, the weight and / or thickness of the product slices forming the portion, and / or the number of the portion forming product slices.
  • the individual product supply can be used to impart predetermined, in particular mutually different, properties to the portions produced in the individual tracks, ie. to achieve that the portions of the individual tracks, in particular different, meet conditions that can be specifically specified.
  • the generation of portions with different number of slices in the individual tracks can be carried out in particular by operating the slicing device in such a way that so-called idle cuts are purposefully carried out in the individual tracks, ie. a track individual Leerterrorismmanagement takes place.
  • a track individual Leerterrorismmanagement takes place.
  • To perform a blank cut it is ensured that, despite a cutting movement performed by the cutting blade of the or the products concerned no disc is separated.
  • the product for which a blank cut is carried out, so that no slice is to be separated from it can be temporarily stopped by corresponding activation of the product feed.
  • the separation of slices from the other product (s) will continue.
  • the goal can be achieved to produce portions with different number of slices during the simultaneous, multi-track slicing of several products in the tracks.

  • the products in the tracks can be fed to the cutting blade in such a way that several parallel conveyors arranged side by side are driven together and the individual speeds of the conveyors are changed individually.
  • the term "variety” used here is to be understood broadly. Thus, not only, for example, sausage on the one hand and cheese on the other hand or in each case different types of meat, sausage or cheese to form mutually different varieties within the meaning of the invention. Even products with "the same content", which differ from one another in terms of at least one parameter which is relevant from the point of view of the end user, should be considered as products of different types.
  • small-diameter salami on the one hand and large-diameter salami on the other hand are intended to represent different product varieties in the sense of the invention.
  • the term "variety" is not to be understood as being broadly equivalent to differences between products that the end-user either does not perceive at all or that are completely irrelevant to the end-user, such as different distributions of the density or constituents of a product, which are naturally always present even when viewed from the consumer's "same" products.
  • the respective portions forming a total portion are produced by the slicing method according to the invention.
  • the total portions can be formed from portions whose slices differ from each other in terms of product variety.
  • the total portions may be formed from portions which differ from one another with regard to the number of their slices, with regard to their portion weight, and / or with regard to the weight and / or the thickness of their slices.
  • the formation of the total portions can take place, for example, during the transport of the portions to a downstream device, in particular to a packaging machine for the total portions.
  • the total portions are formed by the portions being at least partially superimposed.
  • the total portions are formed by the portions being successively introduced into a package, in particular during the transport of the portions to a downstream device, in particular a packaging machine for the total portions.
  • a first portion can be inserted into a package, whereupon one or more further portions are placed on the first portion already in the package.

  • the slicing device comprises, in particular, a product feed which comprises a plurality of conveyors arranged parallel to one another, with which the products can be fed in multiple tracks to a cutting plane in which at least one cutting blade, in particular rotating and / or rotating, moves.
  • the product feed is designed in particular to make the products so individual to the cutting blade to supply each portion with a predetermined condition for the respective track, which relates in particular to the weight of the portion, the weight and / or the thickness of the product discs forming the portion, and / or the number of product slices forming the portion.
  • the conveyors of the product feeder can be operated completely independently of each other. Alternatively it can be provided that the conveyors can be driven together and the individual speeds of the conveyors are individually variable.
  • a likewise claimed production line which comprises at least one slicing device of the type described here and at least one conveying device which can be operated in the manner described here, the conveying device can be connected downstream of at least one packaging machine for the total portions to be produced.
  • the portioned slicing of food products in particular using so-called high-performance slicer, is basically known.
  • the formation of portions is particularly necessary if the slicer is followed by a packaging machine in which not individual product slices, but in each case a plurality of product slices combined in one or more portions are automatically packed.
  • so-called transfer units are known, which are immediately downstream of the slicer and serve both to take the separated product slices and portions and also remove the portions formed in order to supply them downstream devices such as a packaging machine, in particular via other conveyors.
  • An object of such transfer units is also the speed of operation of the slicer to the so-called system speed adapt the downstream devices, because in particular at very fast-working slicers, the portions formed must be removed with a speed from the Portionier Symposium, which is much higher than the system speed.
  • Known transfer units are designed, for example, as combinations of conveyor belts. Portioning takes place on a portioning belt arranged immediately downstream of the slicer, on which the separated product slices are deposited to form the portions. Downstream of the portioning tape is at least one so-called control tape, to which the portions are transferred from the portioning tape.
  • Such transfer units are also used for a so-called portion completions, which is required especially for high-priced products, in the slicing product losses should be kept as low as possible.
  • Portion completion is required if the desired portions are to have a certain number of slices and / or a certain portion weight and the last portion present after slicing a product does not yet meet the respective requirements, i. one or more additional product slices is required if it is not to be disposed of as waste.
  • the transfer unit Since usually at the beginning of the slicing on the new product so-called trim cuts must be performed because the product, for example, does not yet have the required product cross-section, and the resulting in this "trimming", unusable product pieces on the Portionierband and thus on their Completion waiting incomplete partial portion would fall, the transfer unit is operated in the Portionskomplett réelle so that the partial portions are transported by the portioning conveyor in the conveying direction to the control tape, where they await the implementation of trimming cuts. As soon as usable slices can be separated from the new product, the partial portion is transported back again from the control belt to the portioning belt, ie the transfer unit transports the partial portions in this phase against the "normal" conveying direction.
  • the products can be fed to the cutting blade at the same time. If the products have a different length and / or for certain reasons, the product supply in the individual tracks with different or different varying individual speeds, ie individually, then this leads to problems in Portionskomplett réelle, since the slicing of products in the individual tracks is not finished at the same time and so in the individual tracks to be completed Operaportionen temporally succession arise.
  • the invention makes it possible to provide a portion completion in multi-lane slicing of food products.
  • the transfer unit has a separate conveying path for each assigned track, which comprises at least two successive conveying units.
  • the former is particularly advantageous for high-priced products, while the latter substantially improves production hygiene.
  • each time a partial portion is formed in one track it continues with the slicing in the remaining other tracks. Full portions can thus continue to be formed and transported away, even if the slicing of the product has already been completed in one or more tracks.
  • the completion of the partial portions in one lane takes place independently of the completions of the partial portions in the other lanes, wherein in each lane in particular a partial portion formed is completed independently of the formation of partial portions in the other lanes. So it can start with the slicing of a subsequent product and thus with the completion of the present in the track partial portion, while in the other tracks the slicing of the products is still going on. However, such a temporal divergence of completion start is not mandatory.
  • the portion completions in the individual tracks can be coordinated in the individual tracks in such a way that each time a partial portion is formed in one track, it continues with the slicing in the remaining other tracks and only with the completion of the partial portions after the last partial portion is created.
  • Such an approach is for example beneficial if the tracks are loaded with new products at the same time. This can be dependent on the respective application and / or on the design or mode of operation of the respective product feed.
  • the products in the tracks are fed to the cutting blade completely independently of each other.
  • the products in the tracks can be fed to the cutting blade in such a way that a plurality of conveying devices arranged parallel to one another are jointly driven and the individual speeds of the conveying devices are changed individually.
  • track-specific product feeds may be necessary or desired if at least largely constant portion weight is desired and the products differ in terms of their weight or cross-sectional profile of each other.
  • the transfer unit can be configured and operable such that the completion of a partial portion formed on the first conveyor unit can be carried out by intermediate positioning of the partial portion on the second conveyor unit and return of the partial portion to the first conveyor unit.
  • the conveyor units may each comprise a belt conveyor, in particular an endless belt conveyor, which is operable in both the one conveying direction and in the opposite direction.
  • the conveyor sections may be operable such that each time a partial portion is formed on a conveyor line, the transfer of complete portions to the remaining other conveyor lines can be continued.
  • the conveying sections can be operated independently of one another, wherein in particular on each conveying section a resulting partial portion can be completed independently of the formation of partial portions on the other conveying sections.
  • conveyor lines are so coordinated operated operable that at temporally successive partial portions each at If a partial portion is formed on a conveyor line, the transfer of complete portions on the remaining other conveyor lines can continue and the completion of partial portions can be suspended until after the last partial portion has formed.
  • the separated product slices are usually assembled into portions - for example, in a stacked or shingled form - and then fed to further processing devices such as a packaging machine. Since the portions must have a predetermined weight and / or a predetermined number of slices, it may be that at the end of a product only an incomplete portion portion can be cut. Since the further processing of incomplete portions is to be avoided, but on the other hand discarding of product slices is undesirable, particularly in the case of high-quality products, there is a need to complete incomplete partial portions. In principle, this can be done by completing incomplete partial portions at the end of the product after the provision of a new product by product slices of this subsequent product.
  • the feeding of the product in one lane can be interrupted if the remaining product residue in this lane is no longer sufficient to form a complete portion and in at least one of the other lanes the remaining product residue is still sufficient to form at least one complete portion.
  • the product remains are cut into incomplete portions, after the product remains of all traces have reached a level which is insufficient to form a full portion, and the incomplete portions are completed by product slices of subsequent products.
  • Each track will be cut as long as it is possible to create full portions. Once this is no longer possible on a track, the slicing on that track is interrupted and it it waits until the other tracks can no longer produce full portions.
  • the slicing of the product residues resulting in incomplete partial portions then preferably takes place in a product residue exhaustion process common to all the slices. This has the advantage that the incomplete partial portions of all tracks can be conveyed away together from the effective range of the cutting blade in order to make room for the gate and its removal. After completion of the product change or bleed phase, the incomplete partial portions of all tracks can be transported back together, so as to be completed by slices of product to be rearranged subsequent products. An individually controlled conveying the incomplete partial portions is not required. The provision of individually controllable product feeds for the individual tracks is possible with less effort than the provision of individually controllable portioning conveyors.
  • the partial portions are only moved together in and against a conveying direction, in particular a conveying unit undivided transversely to the conveying direction is used. This saves the effort to provide multiple conveyor units or conveyor sub-units.
  • the product when the supply is interrupted, the product is moved into a blank-cut position which is withdrawn relative to the cutting plane. In this way, unwanted chips formation during the interruption of the product supply can be prevented.
  • the slicing of the product residues in the individual tracks can be coordinated in such a way that it ends at the same time in all tracks.
  • the last usable product slice at the end of the product can be cut simultaneously on all lanes.
  • the trailing edges of the incomplete partial portions are then aligned flush. The completing can thus begin on all tracks at the same time.
  • the time sequence of the slicing of the product residues in the individual tracks can be coordinated on the basis of the size of the respective product residues, in particular when the product residues having the largest remaining product residue are cut open.
  • the size of the respective product residues can be detected by suitable sensors.
  • important characteristics of the product such as length, thickness, cross-sectional shape or weight, are in principle recorded and stored before each slicing process. These data can be used advantageously to determine the size of the respective product residues.
  • the completion of the partial portions in all tracks is started simultaneously. This facilitates the coordination of the completion process.
  • the portions in the tracks after the completion are aligned relative to each other with respect to a conveying direction, preferably such that in relation to the conveying direction, the leading edges of the completed portions in all tracks are at the same height.
  • the alignment can be achieved, for example, by means of track-specific, individually controllable belt conveyors - so-called portion-stop belts.
  • the completed portions can be aligned as the regular cut complete portions. That is, in particular, the offset can be compensated, which results from the simultaneous termination of the product residues in the individual tracks and the resulting offset completion of the product residues in the individual tracks. Since the alignment can be done after the completion process at any point of the conveyor line, it is associated with much less effort than if a Portionier digitizer would provide with individually controllable tracks.
  • the slicing of the product residues in all traces is started simultaneously.
