Description

The present invention relates to a method for slicing a product bar into product slices with a slicing apparatus. Furthermore, the present invention relates to a packaging machine for packaging product slices with a plurality of workstations and a slicing apparatus for slicing a product bar into product slices. Moreover, the present invention relates to a system consisting of a slicing device and a packaging machine.

In the field of food processing, for example, when slicing product bars in food slices and their packaging, the aspect of hygiene and compactness of the machines, preferably the smallest possible machine length and / or system length, is becoming increasingly important.

It was therefore the object of the present invention to provide a method, a packaging machine, a slicing device and / or a system consisting of packaging machine and slicing device, which meets high hygienic requirements and the shortest possible length of the machine and / or the system ,

The object is achieved with a method for slicing a product bar into product slices with a slicing device, wherein the sliced product slices are placed directly on a lower film web or in a packaging tray.

The disclosure made on this subject of the present invention applies equally to the other objects of the present invention and vice versa.

The present invention relates to a method for slicing a product bar into product slices. This product bar is in particular a food bar, for example a sausage, cheese or ham bar. A product rod according to the invention may also be a natural ham. This product bar is cut with a slicing device into product slices. The product rod is transported continuously or intermittently in the direction of a moving, preferably rotating, knife, which separates the product slices from the front end of the product rod. The thickness of the discs is determined by the feed travel that the product rod travels between two cuts. The sliced product slices are placed according to the invention directly on a lower film web or in a packaging tray, which is part of a package, or in a packaging tray, which is also part of a package. Preferably, the food slices fall after cutting directly on the lower film web or in a packaging tray.

This object of the present invention has the advantage that at least as far as possible can be dispensed with on conveyor belts, which are normally present next to the slicing device and with which the product slices are transported from the slicing device to the packaging machine and inserted into packaging trays. This shortens the distance within which the product slices can be contaminated with dirt particles or germs. In addition, the system can be made space-saving, which allows the operation of the system even in smaller production facilities.

As a rule, several food slices are put together in one portion. The configuration of this portion is preferably carried out directly on the lower film web or directly in the packaging tray.

Another object of the present invention is a method for cutting a product rod in product slices with a slicing device, in which the cut product slices are placed on a storage table and stored from there to a lower film web and / or in a packaging tray.

The disclosure made on this subject of the present invention applies equally to the other objects of the present invention and vice versa.

Even with this object of the present invention, the food slices are not transported by conveyor belts from the slicing device to the packaging machine. In the present case, a storage table is provided below the cutting blade on which the cut product slices are first deposited and placed there before on the lower film web and / or in a packaging tray or preferably discarded.

This embodiment of the method according to the invention is characterized by improved hygiene. In addition, the inventive method is much more space-saving than the method according to the prior art.

The delivery table preferably has at least one, preferably a plurality of transport means, for example endless belts, which move relative to the delivery table. Further preferably, the storage table is movable in a plane, for example a horizontal plane in at least one spatial direction and / or rotatably provided about one or more axes, in particular a vertical and a horizontal axis. Preferably, the delivery table is located above the lower film web or the packaging tray.

Preferably, the packaging machine operates in cycles, wherein a plurality of, for example, packaging troughs, in particular by deep drawing the lower film web, produced, filled with product slices and closed with a lidding film or only filled and sealed with a lidding film. In one cycle, a so-called format is produced on packages, which preferably consists of a plurality of tracks which are parallel to the running direction of the lower film web, and more preferably a plurality of columns, which are aligned perpendicular to the transport direction of the lower film web. Alternatively, however, a format may also have only one track with one or more packages.

According to a preferred embodiment of the present invention, the portions of at least one column are collected on the delivery table and then placed directly on a lower film web or in a packaging tray, in particular discarded. Then, the bottom web of the packaging machine is indexed by one column, which is filled as soon as a sufficient number of portions have been cut on the tray table.

In a preferred embodiment of the present invention, this tray is also used to sort out bad portions in which the quality of the cut slices does not correspond to the desired quality and / or which do not have a sufficient number of product slices. Further preferably, the storage table can be used to sort out gating slices incurred when first cutting a food bar, and / or end pieces of the food bar that can no longer be cut open in a controlled manner. One or more of these sorting out can take place, for example, in that the delivery table performs a movement transversely to the transport direction of the lower film web / packaging tray or, for example, performs a movement counter to the transport direction of the lower film web / packaging tray. In particular, the bad portions, slices and / or the remaining pieces are preferably conveyed into a container and recycled. Incomplete portions can be used in particular to complete the portion.

According to a further preferred embodiment, an incomplete portion, a poor portion, at least one bleed disk and / or an end piece are collected with a collecting means before it is deposited on the lower film web or in the packaging tray, in particular falls. Alternatively or additionally arrive, in particular fall the incomplete portion, the bad portion, at least one bleed disk and / or the tail on the lower film web and / or in the packaging tray and are removed from there with a removal means again. For example, a robot may be employed therefor having a catch surface selectively positioned in the drop zone downstream of the cutting blade to catch the incomplete portion, the poor portion, at least one gate and / or an end piece. This robot may also alternatively or additionally comprise a gripper, which removes the incomplete portion, the bad portion, at least one bleed disk and / or an end piece of the lower film web or from the packaging tray again.

According to a further preferred or inventive subject matter of the present invention, a message is sent to the downstream packaging machine to mark a portion / package as reject having a bad portion, an incomplete portion, bleed discs and / or an end piece. This portion / package is then removed or changed so that it is a good package. The removal of the packaging is preferably carried out after closing the packaging with a lid film.

Another object of the present invention is a method in which a plurality of product slices are deposited on a lower film web and / or in a packaging tray as a portion and / or multiple portions on a lower film web and / or in a packaging tray.

The disclosure made on this subject of the present invention applies equally to the other objects of the present invention and vice versa.

Preferably, a plurality of product slices are deposited on the lower film web and / or in a packaging tray as a portion. The product slices are stacked or shingled, for example. According to a preferred embodiment, the lower film web and / or the packaging tray is used for shingling relative to the preferably stationary cutting device moves. Alternatively or additionally, the slicing device is moved for shingling relative to the preferably stationary lower film web and / or the preferably stationary packaging hollow. Further preferably, the distance between the slicing device and the film web and / or the packaging tray is changed during the creation of a portion. This preferred embodiment of the present invention is particularly advantageous in a stacked package to ensure that the flight curve of each food slice is always the same for a serving.

FIG. 1 shows the packaging machine 27. In the present case, the packaging machine is a so-called form-fill-seal packaging machine, in which a lower film web 14, in particular cyclically, along the packaging machine, here from right to left, as indicated by the arrow 20 indicated, is transported. The packaging machine 27 is shown only schematically and, in the present case upstream (not shown), has a forming station in which the packaging troughs 13 are formed in the lower film web, in particular under the influence of pressure and heat. These packaging troughs are then transported in the direction of the arrow 20 in the region of a slicing device 26, which is part of the packaging machine according to the invention. This slicing device has a feed unit 11, for example an endless belt, and a moving, here rotating, cutting blade 12, on. A product rod 10 is transported by means of the feed unit 11 in the direction of the cutting blade, which cuts from the front end of the product rod food slices 25, which fall along a fall curve directly into the packaging tray 13, which is symbolized by the arrow 16. The thickness of the food disc is determined by the feed of the product rod 10 between two cuts. In the present case, the portion consisting of several product slices 25 is shingled, ie the slices only partially overlap. To achieve this, either the lower film web 14 or the packaging tray between the dropping of two food slices by a certain amount in or against the transport direction 20 of the lower film web 14 are transported. Alternatively or additionally, the slicing device 26 may be displaced, at least in part, relative to the lower film web 14 and / or the packaging tray 13 to produce a shingled portion. Furthermore, preferably, the position of the slicing device 26 relative to the transport plane of the lower film web 14 and / or the packaging tray 13 can be changed. This can be achieved by changing the position of the slicing device and / or by changing the position of the transport plane of the lower films and / or the packaging tray. For example, this can change the height of fall h. Alternatively or additionally, the feed angle 17 of the product bars can be changed. Both measures alone or in combination lead to a change in the flight curve of the food slices. The person skilled in the art recognizes that a plurality of product bars 10, which are arranged one behind the other in relation to the plane of the paper, can be cut open simultaneously by the knife 12. This embodiment is particularly advantageous if the packaging machine is designed to be multi-lane, ie, if several packages to be filled in relation to the Paper level are arranged one behind the other. Once a portion is arranged in the packaging tray, the lower film web and / or the packaging tray is transported on until an empty packaging tray is in the discharge area of the slicing device. During this time, no product slices may be cut off the product bar, in this case. This preferably takes place in that the cutting blade 12 carries out idle cuts, ie, continues to rotate, preferably with unchanged rotational speed, without cutting food slices 25 off the product bar. This is preferably achieved by retracting the front end of the product bar 10 from the cutting blade, for example with the advancing unit 12, and / or by moving the cutting blade 12 away from the front end of the food bar, preferably parallel to its axis of rotation. The empty sections are preferably carried out until an empty packaging is in the discharge area of the slicing device.

FIG. 2 essentially shows the embodiment according to FIG FIG. 1 In the present case, there is additionally provided a particle trap 18 which prevents particles which are being torn from the product bar during cutting from entering the package. In the present case, the particle catcher is an endless belt with a top belt 18a and a bottom belt 18b, wherein the top belt 18a above the packaging tray 13 or the bottom film 14 and the bottom belt 18b below the bottom film 14 or packaging tray 13 is performed. Preferably, the endless belt is transversely movable to the transport direction 20, preferably provided around two rollers (not shown) circumferentially. As a result, particles which deposit on the particle catcher can be transported away from the discharge area of the slicing apparatus and be removed from the particle catcher, for example with a cleaning agent, for example a scratch. As a result, a continuous or intermittent removal of demolished particles is possible.

FIG. 3 shows an embodiment of the packaging machine according to the invention or the slicing device according to the invention, which substantially according to the embodiment of the packaging machine according to FIG. 1 corresponds, but in the present case has a storage table 19. The cut product slices 25 fall onto the storage table 19 and are configured on it, preferably in portions 15. Preferably, several portions are arranged simultaneously or successively on the tray. Preferably, a plurality of portions 15 are formed or collected on the tray table 19 before they are deposited on the lower film web 14 or inserted into a packaging tray 13. For the storage table preferably at least one conveyor belt, here an endless belt, which rotates in the present case counterclockwise, as soon as one or more portions have been completed. The movement of this conveyor belt can also be used to configure a portion, for example, for shingles. The respective portion falls or slides from the storage table 19 into the packaging 13. Preferably, the delivery table is provided as a whole or partially movable in a plane, for example a horizontal plane, in two spatial directions. This can be done by moving the storage table overall and / or only parts of it, for example the endless belt. Further preferably, the storage table is provided adjustable in height, ie its distance from the cutting blade 12 can be changed. Most preferably, the storage table 19 can be pivoted about at least one horizontal and / or vertical axis and / or rotated. The storage table may have one or more conveyor belts which are preferably operable separately from each other.

It can be seen that the advantage 21, by which the lower film web 14 and / or the packaging troughs 13 are transported further at one cycle, in the present case consists of two columns 29, each with four tracks 28. In the present case, the delivery table 19 is made so broad (horizontal extension transverse to the transport direction) that two finished portions can be simultaneously loaded into the packaging trays in two tracks. At the same time, the delivery table 19 is designed to be so long (horizontal extension parallel to the transport direction) that at least the portions for a deduction for two tracks can be completely taken up by it. In the present case, even the portions for the entire print (two columns and four tracks) can be picked up simultaneously from the tray table. In the present case, the storage table 19, two conveyor belts 23, here two endless transport belts, which can be driven together or independently. In order to be able to occupy the two lower tracks of the trigger with portions 15, the tray table 19 is moved after placing the portions in the upper tracks in the direction 22 of the lower tracks.

FIG. 5 shows a slicing device in which two product bars 10 are cut simultaneously. Also in the present case, the packaging machine according to the invention or the slicing device according to the invention has a storage table, which, as symbolized by the double arrow , is moved transversely to the transport direction 20 in order to provide all tracks 28 with portions 15, although the number the simultaneously cut product bars 10 is smaller than the number of tracks to be loaded simultaneously.

FIG. 6 shows a further embodiment of the slicing device or the packaging machine according to the invention. In the present case, the storage table is also at the same time a discharge organ, with the insufficient portions or gates 24 are discharged. This is done in the present case in that the conveyor belts of the tray table are moved in a clockwise direction and insufficient portions 24 are transferred to another conveyor belt, with which they are removed from the device according to the invention. Further, in the present case, the packaging tray is inclined to be filled relative to the transporting direction 20 to facilitate filling. In addition, in the present case, the transport plane of the lower film web and / or the packaging troughs is raised.
