Definitions

  • the present invention relates to a method and a device for producing a multi-lane portion stream, in which a plurality of food products are fed simultaneously to a slicing unit and cut into portions, product and / or track-specific data being determined before slicing and / or slicing.
  • the food products may in particular be sausage, ham, meat, cheese, baked goods or the like. These are cut into portions, which in particular each have at least one disc.
  • the slicing unit may comprise a rotary knife and / or planetary rotating cutting blade, in particular sickle or circular blade.
  • Such methods or devices are known in principle. On the basis of the determined data, it is determined, for example, how many and with which thickness slices of a product have to be separated in each case in order to obtain portions with a predetermined target weight.
  • a transfer device for example a robot gripper, which is also referred to as a "picker” or "pick and place robot", also work continuously and hand over the portions without interruptions.
  • Breaks in the product stream arise i.a. by loading the slicer with new products in the feed area.
  • the proportion of these loading breaks increases the more the shorter the products to be sliced.
  • This requires buffer sections in the area of the conveying and sorting lines after the slicing unit. The entire system is extended in this way, which is disadvantageous because of the limited space in the user.
  • the product grippers which are also referred to as end gripper or product holder, ensure a uniform product feed for all tracks, see eg EP-A-2 420 364 , Individual product feeding is not possible with these slicing devices.
  • slicing devices with at least two tracks are known in which so-called vario feeders are used.
  • a track-specific product feed can be ensured.
  • the product grippers can be controlled on a track-by-track basis.
  • also feed belts, which form the product support surface can be controlled individually.
  • at least the product grippers can thus be adjusted in the axial direction over a limited length range, in order to cut different lengths and heavy products side by side into uniform portions.
  • a Vario feeder there is the problem at the end of each product loaf that no more portions are created in the relevant track. In an adjacent track, in which, for example, a longer and / or heavier product is cut, portions are still created. So results in a non-continuous portion stream due to different lengths and / or different heavy products.
  • At least one track for example, no more portions are formed, while in at least one other track the usable remainder of a product is cut open. It comes then in the portion stream in the track with the first used up product to a succession of incomplete portions in a row.
  • the object is achieved by a method and a device each having the features of the independent claims 1 and 9.
  • the expected positions of defects in the portion stream are calculated on the basis of the data.
  • the slicing operation is adjusted so that at least some of the actual locations of defects are distributed between the expected positions and the sequence of portions generated from the particular product.
  • a slicing process is not exclusive to slicing a product.
  • the cutting process also includes the performance of so-called idle cuts, ie cutting movements of the knife, in which no slices separated from the product and in particular between successive portions are carried out to allow the removal of complete portions.
  • the slicing process also includes feeding the products and loading the device with the products.
  • a defect corresponds to a missing portion in the portion stream. This is also referred to below as empty portion - based on the term established in the art "blanks".
  • An empty portion can be generated by several immediately consecutive empty cuts in a track. Blank cuts can be generated, for example, by disengaging the cutting blade or stopping or retracting the product.
  • the slicing process can therefore also be influenced by the feed. If e.g. If no product is supplied or the supply is temporarily stopped, at least one empty cut takes place. If the feeder is stopped for a number of blank slices corresponding to one serving, an empty portion is created.
  • the slicing process can be adjusted by the cutting blade itself, e.g. by an axial adjustment of the cutting blade.
  • a control of the feed in particular the product gripper and / or a conveyor belt, a control of a loading rocker and / or an adjustment of the order of the inserted products, e.g. according to the product size, possible.
  • sensors in particular sensors, stops, scanners, in particular contour and / or X-ray scanners, and / or scales, e.g. so-called optical scales, are used.
  • the data of all products of the different tracks can be determined.
  • expected positions and / or the number of defects in the portion stream are calculated according to the invention. If no further influence on the slicing process were taken, defects in these expected positions would arise during normal further operation. In particular, the products would typically be cut open in such a way that successive portions are formed with the respectively specified target weight. The defects inevitably arise in a track as soon as a product is completely cut there and before a new product is inserted and cut becomes. With products of different lengths in different tracks, this results in portions being produced in one lane, while in another lane one or more empty portions are formed, since the shorter product is already completely cut there.
  • the length of a sequence of defects can be kept as low as possible according to the invention.
  • the slicing operation is generally adapted so that at least some actual positions of defects differ from the expected positions.
  • defects are selectively generated, i. Create empty portions at a time when the product in question is not yet completely cut open.
  • the defects become, e.g. with the help of an algorithm, so to speak re-distributed, so that in particular not all defects occur following a completely cut product.
  • an algorithm so to speak re-distributed, so that in particular not all defects occur following a completely cut product.
  • several products of the same and / or different tracks can also be taken into account.
  • the number of immediately consecutive defects can thus be reduced, in particular in the case of slicing devices having at least two tracks.
  • the invention saves design effort, reduces downtime, e.g. by manual corrections of the portion stream or formats, and allows great flexibility of the system.
  • the resorting of the positions of the defects is also advantageous for variable format formation. A large number of successive defects required namely, many other transverse distributions that can be automated with little or no effort.
  • the invention relieves those systems downstream of the slicer which process the portion stream, in particular formatting means such as e.g. Querverteiler.
  • a transverse distribution with minimal design complexity and high throughput can be made such that the portions are handed over four lanes to a packaging device.
  • inventive concept for the retrofitting of existing systems is well suited. It may be enough to just adapt the control accordingly.
  • the slicing process is track-individual.
  • the feed takes place individually, for example by means of a so-called vario feeder.
  • the product holders and / or conveyor belts can be activated, for example, on a track-specific basis, so that the products can be fed to the slicing unit independently of one another, for example at different speeds.
  • products in individual lanes can be stopped consciously or in the opposite direction to the conveying direction to produce empty cuts or empty portions.
  • the positions of the defects can be varied, for example, by changing the order of the products.
  • smaller products can be evenly distributed over the tracks, so that the resulting defects are distributed as evenly as possible and a continuous portion flow is created.
  • the slicing process is adapted such that a plurality of immediately consecutive defects in a track are avoided. In particular, no more than two or three defects are generated in succession. This results in a relatively uniform and especially for downstream devices for formatting particularly easy to handle portion stream.
  • the slicing operation is adapted such that defects are produced in at least one track during the slicing of a product in this track.
  • Targeted defects are generated as it were "in the middle of the product", i. it deliberately creates empty portions even though the product in question has not yet been completely cut open.
  • the defects can be distributed over the product length, which ensures that downstream devices always receive a continuous flow of product and can process the defects well, for example, in the format formation.
  • the defects are generated in a predetermined or predeterminable pattern.
  • the pattern can be especially from Product, depending on current operating condition and / or expected portion flow in downstream equipment.
  • the pattern in a track may include a sequence of two portions and one defect. Also several portions, e.g. three, four, five, six or more consecutively, followed by e.g. one, two or three defects is possible according to the invention.
  • the pattern may cover an entire slicing job, e.g. a batch of a product variety, at least substantially retained.
  • the defects or the patterns are generated as a function of at least one downstream device.
  • the downstream device may be designed for product handling.
  • the downstream device may be a buffer, a depositor, a picker, a transverse distributor, a format image and / or a line-type renderer.
  • the defects are distributed uniformly in the portion flow in at least one track.
  • the slicing operation of at least one further track can be taken into account.
  • the product and / or track-specific data relate to the weight, the density, the volume, the structure, the contour, the length, and / or the sequence of the products in a track.
  • the structure may in particular comprise the density distribution, holes in the product, the distribution of fat and / or any additives, eg pistachios, mushrooms or nuts.
  • the variety of the product can also be recorded in the data record. All determined Data together can serve as the basis for calculating the expected locations of missing portions in the portion stream.
  • measurement results can be obtained, e.g. with the aid of a so-called optical balance, by means of which the cut surface on the product is evaluated in each case so that data calculated from it can be used to correct the product feed.
  • the system can learn from predecessor products.
  • predecessor products e.g. the distribution of the empty portions from at least one predecessor product for a subsequent product, for example, as a default value and / or as a correction value are taken into account.
  • the same or at least similar products or batches are preferably compared and / or evaluated.
  • the invention also relates to a device for producing a multi-lane portion stream, comprising a feed device which feeds a plurality of food products simultaneously to a slicing unit, a measuring device which is designed to determine product and / or track-specific data before slicing and / or during slicing an evaluation device configured to calculate expected positions of defective portions in the portion stream based on the data, and a controller configured to adjust the slicing operation such that at least some actual positions of defects differ from the expected positions.
  • Fig. 1 shows a two-lane slicing device according to the prior art. Products 10 are fed by individual product grippers 12 to a common slicing unit 14.
  • the slicing unit 14 cuts the products 10 into portions 16. In the right lane, the product 10 is already completely cut open, so that only one product residue 18 is left. Portions 16 can no longer be created from product residue 18. The portion stream after the slicing unit 14 thus produces empty portions 20 in the right-hand track, ie defects. Only insofar as it is necessary for the generation of weight-accurate portions 16 are product-specific data with the aid of an in Fig. 1 Not shown measuring device determined and used for the slicing process, in particular the product supply.
  • a measuring device 22 eg a scanner
  • contour data are forwarded together with the also determined total weight of the product to an evaluation device 24 and evaluated there.
  • the so-called cutting plan according to the invention thus preferably also includes a planning of the empty portions 20 to form a product 10.
  • the expected positions of flaws 20 thus correspond to what would arise if the products 10 were cut open without the invention, ie a situation would arise as in Fig. 1 result. There, the product 10 is completely cut open in the right-hand lane, so that a plurality of directly consecutive empty portions 20 are formed in the portion stream.
  • the locations of flaws 20 are distributed over the sequence of portions 16 produced by the particular product. Namely, based on the data obtained by the evaluation device 24, the control device 26 controls the slicing process in such a way that at least some actual positions of flaws 20 are obtained from the expected positions of flaws (cf. Fig. 1 ).
  • control device 26 can control the product grippers 12 and / or the slicing unit 14 in such a way that empty portions 20 are already generated in a targeted manner during the slicing of the product 10 in the right-hand track.
  • the flaws 20 are evenly distributed in this way. Such a portion stream is more favorable for downstream devices, especially for those for format formation.
