Definitions
- the present invention relates to a packaging machine for packaging product slices with a plurality of work stations and a slicing device for slicing a product bar into product slices.
- the present invention also relates to a system consisting of a slicing device and a packaging machine.
- the present invention relates to the slicing of a product stick into product slices.
- This product stick is in particular a food stick, for example a sausage, cheese or ham stick.
- a product stick in the sense of the invention can also be a natural ham.
- This product stick is sliced into product slices using a slicing device.
- the product stick is transported continuously or intermittently in the direction of a moving, preferably rotating, knife, which cuts the product slices from the front end of the product stick.
- the thickness of the slices is determined by the feed path that the product stick travels between two cuts.
- the cut product slices are placed in a packaging tray that is part of a package. After cutting, the food slices preferably fall directly onto the bottom film web or into a packaging tray.
- conveyor belts which are normally present next to the slicing device and which transport the product slices from the slicing device to the packaging machine and place them in packaging trays, can be largely dispensed with. This shortens the distance over which the product slices can become contaminated with dirt particles or germs.
- the system can be designed to save space, which also allows the system to be operated in smaller production facilities.
- this portion preferably takes place directly on the bottom film web or directly in the packaging tray.
- the food slices are also not transported from the slicing device to the packaging machine using conveyor belts.
- a deposit table is provided below the cutting knife, on which the cut product slices are first deposited and from there placed on the bottom film web and/or in a packaging trough or preferably thrown off.
- This embodiment of the disclosed method is also characterized by improved hygiene.
- the method is significantly more space-saving than methods according to the prior art.
- the storage table preferably has at least one, preferably several transport means, for example endless belts, which move relative to the storage table.
- the storage table is also preferably movable in a plane, for example a horizontal plane, in at least one spatial direction and/or rotatable about one or more axes, in particular a vertical and a horizontal axis.
- the storage table is preferably located above the bottom film web or the packaging tray.
- the packaging machine preferably works in cycles, with a plurality of packaging trays, for example, being produced in one cycle, in particular by deep-drawing the bottom film web, filled with product slices and closed with a cover film or just filled and closed with a cover film.
- a so-called format of packaging is produced, which preferably consists of several tracks that are parallel to the running direction of the bottom film web and particularly preferably several columns that are aligned perpendicular to the transport direction of the bottom film web.
- a format can also have just one track with one or more packages.
- the portions of at least one column are collected on the deposit table and then placed, in particular dropped, directly onto a bottom film web or into a packaging tray.
- the bottom film web of the packaging machine is then cycled further by one column, which is filled as soon as a sufficient number of portions have been cut open on the deposit table.
- this storage table is also used to sort out bad portions where the quality of the sliced slices does not correspond to the desired quality and/or which do not have a sufficient number of product slices.
- the storage table can also preferably be used to sort out cut slices that arise when a food bar is cut for the first time and/or end pieces of the food bar that can no longer be cut in a controlled manner.
- One or more of these sortings can be carried out, for example, by the storage table moving transversely to the transport direction of the bottom film web/packaging trough or, for example, moving against the transport direction of the bottom film web/packaging trough.
- the bad portions, cut slices and/or the leftover pieces are preferably conveyed into a container and used for another purpose. Incomplete portions can be used in particular to complete portions.
- an incomplete portion, a bad portion, at least one cut slice and/or an end piece is caught with a collecting means before it is deposited, in particular falls, on the bottom film web or into the packaging tray.
- the incomplete portion, the bad portion, at least one cut slice and/or the end piece reach, in particular fall, on the bottom film web and/or into the packaging tray and are removed there again using a removal device.
- a robot can be used for this purpose which has a collecting surface which is optionally arranged in the discharge area downstream of the cutting blade in order to collect the incomplete portion, the bad portion, at least one cut slice and/or an end piece.
- This robot can also alternatively or additionally have a gripper which removes the incomplete portion, the bad portion, at least one cut slice and/or an end piece from the bottom film web or from the packaging trough.
- Several product slices can be placed on a bottom film web and/or in a packaging tray as a portion and/or several portions can be placed on a bottom film web and/or in a packaging tray.
- the bottom film web and/or the packaging tray is moved relative to the preferably stationary slicing device for shingling.
- the slicing device is moved relative to the preferably stationary bottom film web and/or the preferably stationary packaging tray for shingling.
- the distance between the slicing device and the film web and/or the packaging tray is preferably changed during the creation of a portion. This preferred embodiment is particularly advantageous in the case of stacked packaging in order to ensure that the flight path of each food slice in a portion is always the same.
- a bottom film web and/or in a packaging tray i.e. in a package. These can be arranged one above the other or next to each other and can be stacked or shingled.
- the cutting blade of the slitting device can make empty cuts during the further transport of the bottom film web or the packaging tray.
- the cutting knife In order to transport the packaging further, it may be necessary for the cutting knife to make so-called empty cuts, during which the cutting knife performs its movement, for example its rotary and/or orbital movement, without cutting food slices from the product bar.
- empty cuts can This can be achieved by pulling the product bar back from the cutting blade and/or by moving the cutting blade away from the front end of the food bar.
- no slices are cut off that would then have to be temporarily stored.
- no so-called snippets are created, i.e. incompletely severed food slices that would then fall onto the bottom film web or into the packaging tray.
- the further transport of the bottom film web or the packaging takes place so quickly that the food bar cannot deform to the point where it gets caught in the cutting blade, despite the front end being at a distance from the cutting blade.
- the bottom film web and/or a packaging tray and the slicing device can be moved relative to each other during slicing.
- This embodiment is particularly advantageous for producing portions on the bottom film web or in the packaging tray.
- the relative movement can take place in a horizontal and/or vertical plane.
- the bottom film web and/or a packaging tray can be tilted for filling with at least one food slice.
- the packaging tray is tilted for filling with at least one slice of food, but preferably with a portion.
- the insertion is preferably carried out using a storage table, which preferably has an insertion belt.
- the inclination of the packaging means that the slice of food or the portion can be inserted very easily and without vibration.
- the inclination preferably takes place around a particularly preferably horizontal axis, which is most preferably aligned transversely to the transport direction of the bottom film web or the packaging tray.
- a portion consisting of several product slices can be weighed in the packaging during slicing or immediately after slicing.
- the packaging machine has a scale, which is preferably arranged below the cutting blade.
- the food slices that fall into the respective packaging trough or onto the bottom film web are immediately weighed. it can be ensured on site that the respective packaging has the required TARGET weight. If the ACTUAL weight is too low, one or more product slices are cut off and placed on the bottom film web or in the packaging trough. If the ACTUAL weight is too high, the preferred procedure is for the machine or system control to remember the affected packaging and, after the packaging has been separated in the cutting station, to eject it from the process or for one or more food slices to be removed from the packaging. It is particularly preferred to weigh the individual slices during the process and, shortly before the TARGET weight is reached, to use forecast calculations to achieve the TARGET weight particularly accurately, thus avoiding overweight packaging with a particularly high degree of probability.
- the slicing device can have a feed for the product bar and a moving, in particular rotating, cutting knife which cuts product slices from the product bar, wherein the movement of the feed and/or the cutting knife is controlled as a function of the feed of the bottom film web and/or the packaging tray.
- the slicing device has a feed with which the product bar is moved in the direction of the cutting knife. Furthermore, the slicing device has a moving, preferably rotating, cutting knife that cuts product slices from the front end of the product bar. For portioning or further transport of the packaging, it may be necessary for the cutting knife to carry out so-called empty cuts, during which the cutting knife carries out its movement without food slices being severed from the product bar. These empty cuts can be achieved by pulling the product bar back from the cutting knife and/or by moving the cutting knife away from the front end of the food bar.
- At least one of the movements of the feed and/or the cutting knife can be controlled depending on the feed of the bottom film web and/or the packaging tray.
- the packaging machine has the so-called “lead” in terms of control technology, ie the movements of the cutting device follow signals generated by the packaging machine.
- the slicing device has a feed for the product bar and a moving, in particular rotating, cutting knife which cuts product slices from the product bar and in which the feed of the bottom film web and/or the packaging tray is controlled as a function of the movement of the feed and/or the cutting knife.
- the advance of the bottom film web and/or the packaging tray is controlled depending on the movement of the advance and/or the cutting knife.
- the slicing device has the lead. This method is particularly advantageous when so-called shingled portions are to be produced and the movement of the bottom film web or the packaging tray relative to the cutting knife takes place by a movement of the bottom film web or the packaging tray itself.
- the slicing device preferably has several so-called feed paths, along each of which a product bar is transported. During a cyclical movement of the cutting blade, for example a rotation, several product slices are cut off essentially simultaneously.
- the number of products is different, in particular smaller or larger, or equal to the number of tracks of the packaging machine.
- a storage table is preferably provided, which can be moved in particular transversely to the transport direction of the bottom film web or the packaging trough and on which a number of portions corresponding to the number of tracks that are loaded in one cycle can be placed before they are placed in the packaging troughs.
- not all tracks of a product are filled with a portion at the same time, but at least partially one after the other.
- not all food bars in the slicing device are cut off a slice when the blade is rotated. This is preferably done in particular when the number of products, the food bars, is larger than the number of tracks of the packaging machine.
- the product can be withdrawn from the cutting plane, for example.
- the method uses a storage table to adjust the number of product bars cut off at the same time to the number of tracks.
- a storage table to adjust the number of product bars cut off at the same time to the number of tracks.
- each portion has product slices from different product bars. This can be achieved, for example, by moving a storage table while a portion is being cut open so that the respective portion is arranged in alternating trajectories of the food slices of the respective food.
- the subject matter of the present invention is a packaging machine for packaging product slices, having a plurality of work stations, wherein one work station is a slicing device.
- the present invention relates to a packaging machine for packaging product slices with a plurality of work stations, for example a forming station in which packaging troughs are formed, for example deep-drawn, into a bottom film web, optionally an insertion station in which the product slices are placed in the packaging troughs, a sealing station in which a lid film is sealed to the bottom film web in order to hermetically seal the filled packages, and preferably a cutting station in which the packages are separated.
- a packaging machine for packaging product slices with a plurality of work stations for example a forming station in which packaging troughs are formed, for example deep-drawn, into a bottom film web, optionally an insertion station in which the product slices are placed in the packaging troughs, a sealing station in which a lid film is sealed to the bottom film web in order to hermetically seal the filled packages, and preferably a cutting station in which the packages are separated.
- this packaging machine now also has a slicing machine with which a product bar, also called a product loaf, is divided into a large number of product slices. These product slices are then packed in packaging.
- the slicing device is provided in the area of the so-called insertion station. It is particularly preferably located above the insertion station so that the cut food slices fall onto the bottom film web or into the packaging trough.
- the packaging machine and the slicing device have a common frame.
- the slicing device preferably has means by means of which the bottom film web and/or the packaging troughs are guided and/or transported along the packaging machine. These means can move in two opposite directions in order to produce shingled portions, for example.
- the packaging machine is a so-called tray sealer, in which prefabricated individual packaging trays are filled with a packaged product and these packaging trays are then sealed with a cover film.
- the packaging trays are delivered to the packaging machine in stacks, so that the tray sealer has a so-called separating station in which the packaging trays are unstacked, i.e. separated.
- the cutting device is located downstream of the packaging tray separating station and upstream of a sealing station in which a cover film is sealed to the packaging tray.
- the distance between two packaging troughs upstream of the slicing device is adjusted to a desired size.
- the packaging machine has means by means of which it is possible to determine where the respective packaging trough is located in the packaging machine, so that its transport can be controlled or regulated in such a way that it is located exactly below the flight path of the food slices for loading and/or in the deposit area of a deposit table, if present.
- a slicing device for slicing a product bar into product slices which has a means for guiding and/or transporting the bottom film and/or a packaging tray.
- Another disclosed subject matter is a slicing device for slicing a product bar into product slices, which has a recess through which a packaging machine can be passed.
- the slicing device has a frame with a recess that is large enough for the packaging machine to be guided through. This allows the slicing device to be pushed onto the packaging machine, for example, from one end of the packaging machine and then along or against the transport direction of the bottom film web and/or the packaging tray. be moved along the packaging machine until the slicing device is in the desired position. This position can be changed as desired. To clean the packaging machine and/or the slicing device, the slicing device can be moved relative to the packaging machine or removed from the packaging machine. In a further embodiment, the slicing device is designed to be at least partially pivotable away and/or open, preferably pivotable up, for example to enable or facilitate cleaning of the packaging machine and/or the slicing device.
- the packaging machine has a means that prevents product particles from getting into the packaging.
- the slicing device and/or the packaging machine now has at least one means that prevents such particles from getting into the packaging.
- the means is a sheet or a band that is arranged in the area of the cutting knife, preferably below the cutting knife and particularly preferably at least partially above the bottom film web or the packaging tray, and thereby prevents product particles from getting into the packaging.
- the means can also be a gas, in particular air, stream that, for example, sucks and/or blows away the particles as they are formed or from the packaging tray.
- the means is a means that, for example, generates an electrical charge that attracts or repels the product particles and thus keeps them away from the packaging tray.
- Another disclosed subject matter is a slicing device for slicing a product bar into product slices, which has a deposit table which is additionally a feeder and which places the product slices and/or portions on a bottom film web or in a packaging tray.
- the slicing device has a deposit table, which is preferably provided below the cutting blade and onto which the food slices fall after cutting.
- This deposit table is also a feeder, which places or deposits the product slices or portions onto a bottom film web or into a packaging tray.
- the deposit table is preferably provided with at least one, particularly preferably with several, endless belts, which, after For example, once one or more portions have been completed on the storage table, place them on the bottom film track or in a packaging tray.
- the endless belts can be driven together or independently of one another.
- the deposit table is preferably designed as a so-called shuttle belt.
- a shuttle belt is an endless belt that has a quickly retractable front edge that is actuated while the endless belt is preferably stationary. This causes the product slices or portions to fall essentially vertically onto the bottom film or into the packaging trough.
- the storage table is movable in at least one plane in one or more spatial directions, which are particularly preferably arranged parallel or perpendicular to one another.
- the table is movable horizontally in a plane in at least one, preferably two, or more spatial directions.
- the storage table is height-adjustable, i.e. it can be adjusted in height towards the cutting blade and away from it. This means that the storage table can be vertically spaced from the product bar and/or the cutting blade, for example, so that each product slice has the same or a deliberately different drop height, for example to achieve a symmetrical deposit pattern of the product slices.
- the table and/or the belts provided with it are moved by a defined distance in, for example, a horizontal direction before each product slice is cut, in order to achieve a pronounced shingle pattern or, when moved in the opposite direction, for example a particularly straight stack of slices.
- the storage table can be rotated around a horizontal axis. This means that the storage table can be tilted, for example, after a portion has been completed, which makes it easier to place it on a bottom film web or place it in a packaging tray. Alternatively or additionally, the storage table can be rotated around a vertical axis, for example to produce circular portions.
- the storage table is designed as a scale so that while a portion is being cut it can be determined whether it has the desired minimum weight.
- Another disclosed subject matter is a slicing device for slicing a product bar into product slices or a packaging machine, each in particular as described above, wherein it comprises a sensor which detects at least one quality feature of the product slices and/or the portions.
- a quality feature is, for example, the temperature, the color, the slice shape and/or the slice size, the portion shape and/or the portion size, fat content, so-called "blood spots", too few or too many holes, especially in cheese, and/or the presence of foreign bodies.
- the sensor signal is preferably forwarded to a control system, which sorts out slices of poor quality, for example.
- the storage table, the collecting device and/or a removal device can be used for this.
- packages with a defective product can be sorted out, especially after they have been sealed with a lid film.
- a further disclosed subject matter is a slicing device for slicing a product bar into product slices and/or a packaging machine, in each case in particular as described above, which has an irradiation means which preferably irradiates the cut portion of the product bar and/or the cut product slice and/or the sliced portion and thereby at least partially disinfects it.
- the slicing device and/or the packaging machine has an irradiation means which irradiates the cut portion of the food bar and/or the cut product slice and/or the cut portion and thereby at least partially disinfects it.
- This design of the slicing device has the advantage that the shelf life of the product slices in the produced packaging is increased.
- the cut product slice is irradiated on both cut surfaces.
- the slicing device or the packaging machine has a means by which the rays of the irradiation agent are directed specifically onto the cut and/or the cut product slice and/or the sliced portion.
- Another disclosed subject matter is a packaging machine or a slicing device which has a means for changing the position of the bottom film web and/or a packaging tray and the slicing device relative to each other.
- the vertical distance between the cutting knife and the transport plane of the bottom film web and/or a packaging tray can be changed.
- the angle at which the slicing device, in particular the cutting knife, and/or the feed unit of the product bar are arranged relative to the transport plane of the bottom film web or the packaging tray is changed.
- the fall height, the fall angle or the fall curve can be changed in relation to the plane in which the bottom film web or the packaging is guided.
- Another object of the present invention is a system according to claim 3.
- a further disclosed subject matter is a slicing device and/or a packaging machine, in each case in particular as described above, in which the region of the knife and/or the discharge region of the cut-off food slice and/or the insertion region is provided with negative pressure and/or a modified atmosphere.
- the cutting and/or ejection and/or insertion of the respective food slice takes place under a changed atmosphere compared to the ambient atmosphere.
- this changed atmosphere is also present in the area of the bottom film web or the packaging tray.
- the knife and/or the ejection area and/or the insertion area can be at least partially encapsulated and under negative pressure and/or a gas with a different composition than air can be introduced into this encapsulation.
- the negative pressure and/or the changed atmosphere then surrounds the cut-off slice in the packaging at least temporarily, in particular until it is sealed with a lidding film.
- FIG. 1 shows a packaging machine 27.
- the packaging machine is a so-called form-fill-seal packaging machine, in which a bottom film web 14 is transported, in particular in cycles, along the packaging machine, here from right to left, as indicated by the arrow 20.
- the packaging machine 27 is only shown schematically and in the present case has a forming station upstream (not shown) in which the packaging troughs 13 are formed into the bottom film web, in particular under the influence of pressure and heat.
- These packaging troughs are then transported in the direction of the arrow 20 into the area of a slicing device 26, which according to the invention is part of the packaging machine.
- This slicing device has a feed unit 11, for example an endless belt, and a moving, here rotating, cutting knife 12.
- a product bar 10 is transported by means of the feed unit 11 in the direction of the cutting knife, which cuts off food slices 25 from the front end of the product bar, which fall along a falling curve directly into the packaging trough 13, which is symbolized by the arrow 16.
- the thickness of the food slice is determined by the advance of the product bar 10 between two cuts.
- the portion, which consists of several product slices 25, is shingled, i.e. the slices only partially overlap.
- either the bottom film web 14 or the packaging trough can be transported by a certain amount in or against the transport direction 20 of the bottom film web 14 between the dropping of two food slices.
- the slicing device 26 can be displaced, at least partially, relative to the bottom film web 14 and/or the packaging trough 13 in order to produce a shingled portion.
- the position of the slicing device 26 can preferably be changed relative to the transport plane of the bottom film web 14 and/or the packaging tray 13. This can be done by changing the position of the slicing device and/or by changing the position of the transport plane the bottom film and/or the packaging trough.
- the drop height h can be changed in this way.
- the feed angle 17 of the product sticks can be changed. Both measures alone or in combination lead to a change in the flight curve of the food slices.
- the cutting blade 12 makes idle cuts, ie continuing to rotate, preferably at an unchanged speed, without food slices 25 being cut off from the product bar. This is preferably achieved by the front end of the product bar 10 being pulled back by the cutting blade, for example with the feed unit 12 and/or by the cutting blade 12 being moved away from the front end of the food bar, preferably parallel to its axis of rotation.
- the idle cuts are preferably carried out until an empty package is located in the discharge area of the slicing device.
- Figure 2 essentially shows the embodiment according to Figure 1 , wherein in the present case a particle catcher 18 is additionally provided, which prevents particles that are torn off the product bar during cutting from getting into the packaging.
- the particle catcher is an endless belt with an upper belt 18a and a lower belt 18b, wherein the upper belt 18a is guided above the packaging trough 13 or the lower film web 14 and the lower belt 18b is guided below the lower film web 14 or packaging trough 13.
- the endless belt is preferably movable transversely to the transport direction 20, preferably provided so as to encircle two rollers (not shown). This allows particles that settle on the particle catcher to be transported away from the discharge area of the slicing device and removed from the particle catcher, for example with a cleaning agent, for example a scraper. This enables continuous or intermittent removal of torn-off particles.
- Figure 3 shows an embodiment of a packaging machine or a slicing device which essentially corresponds to the embodiment of the packaging machine according to Figure 1 corresponds, but which in the present case has a storage table 19.
- the cut product slices 25 fall onto the storage table 19 and are configured thereon, preferably into portions 15.
- several portions are arranged on the storage table simultaneously or one after the other.
- several portions 15 are formed or collected on the storage table 19 before they are placed on the bottom film web 14 or placed in a packaging trough 13.
- the storage table preferably has at least one conveyor belt, here an endless belt, which in the present case rotates anti-clockwise 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 shingling.
- the respective portion falls or slides from the storage table 19 into the packaging 13.
- the storage table is provided as a whole or partially movable in one plane, for example a horizontal plane, in two spatial directions. This can be done by moving the storage table as a whole and/or only parts of it, for example the endless belt.
- the storage table is also preferably provided so that it is height-adjustable, ie its distance from the cutting blade 12 can be changed.
- the storage table 19 can very particularly preferably be pivoted and/or rotated about at least one horizontal and/or vertical axis.
- the storage table can have one or more conveyor belts, which can preferably be operated separately from one another.
- Figure 4 shows a top view of a packaging machine or the slicing device. It can be seen that the feed 21, around which the bottom film web 14 and/or the packaging troughs 13 are transported in one cycle, in the present case consists of two columns 29 each with four tracks 28.
- the deposit table 19 is designed to be so wide (horizontal extension transverse to the transport direction) that two finished portions can be placed simultaneously in the packaging troughs in two tracks. At the same time, the deposit table 19 is designed to be so long (horizontal extension parallel to the transport direction) that it can completely accommodate at least the portions for one take-off for two tracks. In the present case, even the portions for the entire take-off (two columns and four tracks) can be accommodated by the deposit table at the same time.
- the deposit table 19 has two conveyor belts 23, here two endless conveyor belts, which can be driven together or independently of one another. To also remove the two lower tracks of the trigger In order to be able to fill the tray with portions 15, the storage table 19 is moved in the direction 22 of the lower tracks after the portions have been placed in the upper tracks.
- Figure 5 shows a slicing device in which two product bars 10 are cut open simultaneously.
- the packaging machine or the slicing device also has a storage table which, as symbolized by the double arrow, is moved transversely to the transport direction 20 in order to be able to supply all tracks 28 with portions 15, although the number of product bars 10 cut open simultaneously is smaller than the number of tracks to be fed simultaneously.
- Figure 6 shows a further embodiment of the slicing device or the packaging machine.
- the deposit table is also simultaneously a discharge device with which insufficient portions or cuts 24 are discharged. In the present case, this is done by moving the conveyor belts of the deposit table clockwise and transferring insufficient portions 24 to another conveyor belt with which they are removed from the device.
- the packaging trough is inclined relative to the transport direction 20 in order to fill it in order to facilitate filling.
- the transport level of the bottom film web and/or the packaging troughs is raised.

Description
Die vorliegende Erfindung betrifft eine Verpackungsmaschine zum Verpacken von Produktscheiben mit einer Mehrzahl von Arbeitsstationen sowie einer Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben. Außerdem betrifft die vorliegende Erfindung ein System, bestehend aus einer Aufschneidevorrichtung und einer Verpackungsmaschine.The present invention relates to a packaging machine for packaging product slices with a plurality of work stations and a slicing device for slicing a product bar into product slices. The present invention also relates to a system consisting of a slicing device and a packaging machine.
Im Bereich der Lebensmittelverarbeitung, beispielsweise beim Aufschneiden von Produktstangen in Lebensmittelscheiben und deren Verpackung, kommt dem Aspekt der Hygiene und der Kompaktheit der Maschinen, vorzugsweise der möglichst geringen Maschinenlänge und/oder Systemlänge, eine immer größere Bedeutung zu. Der nächstliegende Stand der Technik ist die
Es war deshalb die Aufgabe der vorliegenden Erfindung eine Verpackungsmaschine und/oder ein System, bestehend aus Verpackungsmaschine und Aufschneidevorrichtung, zur Verfügung zu stellen, das hohen hygienischen Anforderungen und möglichst geringer Länge der Maschine und/oder des Systems genügt.It was therefore the object of the present invention to provide a packaging machine and/or a system consisting of a packaging machine and a slicing device that meets high hygienic requirements and the shortest possible length of the machine and/or the system.
Gelöst wird die Aufgabe einer Verpackungsmaschine gemäß Patentanspruch 1.The task of a packaging machine is solved according to patent claim 1.
Die zu diesem Gegenstand der vorliegenden Erfindung gemachte Offenbarung gilt für die anderen Gegenstände der vorliegenden Erfindung gleichermaßen und umgekehrt.The disclosure made with respect to this subject matter of the present invention applies equally to the other subject matters of the present invention and vice versa.
Die vorliegende Erfindung betrifft das Aufschneiden einer Produktstange in Produktscheiben. Bei dieser Produktstange handelt es sich insbesondere um eine Lebensmittelstange, beispielsweise um eine Wurst-, Käse-, oder Schinkenstange. Eine Produktstange im Sinne der Erfindung kann aber auch ein Naturschinken sein. Diese Produktstange wird mit einer Aufschneidevorrichtung in Produktscheiben aufgeschnitten. Dabei wird die Produktstange kontinuierlich oder intermittierend in Richtung eines sich bewegenden, vorzugsweise rotierenden, Messers transportiert, das von dem vorderen Ende der Produktstange die Produktscheiben abtrennt. Die Dicke der Scheiben wird durch den Vorschubweg, den die Produktstange zwischen zwei Schnitten zurücklegt, bestimmt. Die abgeschnittenen Produktscheiben werden in eine Verpackungsmulde platziert, die Teil einer Verpackung ist. Vorzugsweise fallen die Lebensmittelscheiben nach dem Abschneiden direkt auf die Unterfolienbahn oder in eine Verpackungsmulde.The present invention relates to the slicing of a product stick into product slices. This product stick is in particular a food stick, for example a sausage, cheese or ham stick. A product stick in the sense of the invention can also be a natural ham. This product stick is sliced into product slices using a slicing device. The product stick is transported continuously or intermittently in the direction of a moving, preferably rotating, knife, which cuts the product slices from the front end of the product stick. The thickness of the slices is determined by the feed path that the product stick travels between two cuts. The cut product slices are placed in a packaging tray that is part of a package. After cutting, the food slices preferably fall directly onto the bottom film web or into a packaging tray.
Dies hat den Vorteil, dass auf Förderbänder, die normalerweise anschließend an die Aufschneidevorrichtung vorhanden sind und mit denen die Produktscheiben von der Aufschneidevorrichtung zu der Verpackungsmaschine transportiert und dort in Verpackungsmulden eingelegt werden, zumindest weitestgehend verzichtet werden kann. Dadurch verkürzt sich die Wegstrecke, innerhalb derer die Produktscheiben mit Schmutzpartikeln oder Keimen kontaminiert werden können. Zudem kann das System dadurch platzsparender gestaltet werden, was das Betreiben des Systems auch in kleineren Produktionsstätten gestattet.This has the advantage that conveyor belts, which are normally present next to the slicing device and which transport the product slices from the slicing device to the packaging machine and place them in packaging trays, can be largely dispensed with. This shortens the distance over which the product slices can become contaminated with dirt particles or germs. In addition, the system can be designed to save space, which also allows the system to be operated in smaller production facilities.
In der Regel werden mehrere Lebensmittelscheiben zu einer Portion zusammengestellt. Die Konfiguration dieser Portion erfolgt vorzugsweise direkt auf der Unterfolienbahn oder direkt in der Verpackungsmulde.As a rule, several food slices are put together to form a portion. The configuration of this portion preferably takes place directly on the bottom film web or directly in the packaging tray.
Nicht beansprucht aber offenbart ist auch ein Verfahren zum Aufschneiden einer Produktstange in Produktscheiben mit einer Aufschneidevorrichtung, bei dem die abgeschnittenen Produktscheiben auf einem Ablagetisch abgelegt und von dort auf eine Unterfolienbahn und/oder in eine Verpackungsmulde abgelegt werden.Also not claimed but disclosed is a method for cutting a product bar into product slices using a cutting device, in which the cut product slices are placed on a storage table and from there placed on a bottom film web and/or in a packaging tray.
Auch bei diesem Gegenstand der vorliegenden Offenbarung werden die Lebensmittelscheiben nicht mit Förderbändern von der Aufschneidevorrichtung zu der Verpackungsmaschine transportiert. In dem vorliegenden Fall ist unterhalb des Schneidmessers ein Ablagetisch vorgesehen, auf dem die abgeschnittenen Produktscheiben zunächst abgelegt und vor dort auf die Unterfolienbahn und/oder in eine Verpackungsmulde gelegt oder vorzugsweise abgeworfen werden.In this subject matter of the present disclosure, the food slices are also not transported from the slicing device to the packaging machine using conveyor belts. In the present case, a deposit table is provided below the cutting knife, on which the cut product slices are first deposited and from there placed on the bottom film web and/or in a packaging trough or preferably thrown off.
Auch diese Ausführungsform des offenbarten Verfahrens zeichnet sich durch eine verbesserte Hygiene aus. Außerdem ist das Verfahren wesentlich platzsparender als Verfahren gemäß dem Stand der Technik.This embodiment of the disclosed method is also characterized by improved hygiene. In addition, the method is significantly more space-saving than methods according to the prior art.
Vorzugsweise weist der Ablagetisch mindestens ein, vorzugsweise mehrere Transportmittel, beispielsweise Endlosbänder, auf, die sich relativ zu dem Ablagetisch bewegen. Weiterhin bevorzugt ist der Ablagetisch in einer Ebene, beispielsweise einer Horizontalebene in mindestens eine Raumrichtung bewegbar und/oder um eine oder mehrere Achsen, insbesondere eine Vertikal- und eine Horizontalachse drehbar vorgesehen. Vorzugsweise befindet sich der Ablagetisch oberhalb von der Unterfolienbahn bzw. der Verpackungsmulde.The storage table preferably has at least one, preferably several transport means, for example endless belts, which move relative to the storage table. The storage table is also preferably movable in a plane, for example a horizontal plane, in at least one spatial direction and/or rotatable about one or more axes, in particular a vertical and a horizontal axis. The storage table is preferably located above the bottom film web or the packaging tray.
Vorzugsweise arbeitet die Verpackungsmaschine taktweise, wobei bei einem Takt eine Mehrzahl von beispielsweise Verpackungsmulden, insbesondere durch Tiefziehen der Unterfolienbahn, hergestellt, mit Produktscheiben befüllt und mit einer Deckelfolie geschlossen oder nur befüllt und mit einer Deckelfolie verschlossen wird. Bei einem Takt wird ein sogenanntes Format an Verpackungen hergestellt, das vorzugsweise aus mehreren Spuren, die parallel zur Laufrichtung der Unterfolienbahn, und besonders bevorzugt mehreren Spalten, die senkrecht zur Transportrichtung der Unterfolienbahn ausgerichtet sind, besteht. Alternativ kann ein Format aber auch nur eine Spur mit einer oder mehreren Verpackungen aufweisen.The packaging machine preferably works in cycles, with a plurality of packaging trays, for example, being produced in one cycle, in particular by deep-drawing the bottom film web, filled with product slices and closed with a cover film or just filled and closed with a cover film. In one cycle, a so-called format of packaging is produced, which preferably consists of several tracks that are parallel to the running direction of the bottom film web and particularly preferably several columns that are aligned perpendicular to the transport direction of the bottom film web. Alternatively, a format can also have just one track with one or more packages.
Gemäß einer bevorzugten Ausführungsform werden auf dem Ablagetisch die Portionen mindestens einer Spalte gesammelt und dann direkt auf eine Unterfolienbahn oder in eine Verpackungsmulde eingelegt, insbesondere abgeworfen. Sodann wird die Unterfolienbahn der Verpackungsmaschine um eine Spalte weitergetaktet, die befüllt wird, sobald eine ausreichende Anzahl an Portionen auf dem Ablagetisch aufgeschnitten worden sind.According to a preferred embodiment, the portions of at least one column are collected on the deposit table and then placed, in particular dropped, directly onto a bottom film web or into a packaging tray. The bottom film web of the packaging machine is then cycled further by one column, which is filled as soon as a sufficient number of portions have been cut open on the deposit table.
In einer bevorzugten Ausführungsform wird dieser Ablagetisch auch dazu verwendet, schlechte Portionen, bei denen die Qualität der aufgeschnittenen Scheiben nicht der gewünschten Qualität entspricht und/oder die nicht eine ausreichende Zahl an Produktscheiben aufweisen, auszusortieren. Weiterhin bevorzugt kann der Ablagetisch dazu verwendet werden Anschnittscheiben, die beim erstmaligen Anschneiden eines Lebensmittelriegels anfallen und/oder Endstücke des Lebensmittelriegels, die nicht mehr kontrolliert aufgeschnitten werden können, auszusortieren. Eine oder mehrere dieser Aussortierungen können beispielsweise dadurch erfolgen, dass der Ablagetisch eine Bewegung quer zur Transportrichtung der Unterfolienbahn/Verpackungsmulde durchführt oder beispielsweise eine Bewegung entgegen der Transportrichtung der Unterfolienbahn/Verpackungsmulde durchführt. Insbesondere die Schlechtportionen, Anschnittscheiben und/oder die Reststücke werden vorzugsweise in einen Behälter gefördert und einer anderen Verwertung zugeführt. Unvollständige Portionen können insbesondere zur Portionskomplettierung herangezogen werden.In a preferred embodiment, this storage table is also used to sort out bad portions where the quality of the sliced slices does not correspond to the desired quality and/or which do not have a sufficient number of product slices. The storage table can also preferably be used to sort out cut slices that arise when a food bar is cut for the first time and/or end pieces of the food bar that can no longer be cut in a controlled manner. One or more of these sortings can be carried out, for example, by the storage table moving transversely to the transport direction of the bottom film web/packaging trough or, for example, moving against the transport direction of the bottom film web/packaging trough. In particular, the bad portions, cut slices and/or the leftover pieces are preferably conveyed into a container and used for another purpose. Incomplete portions can be used in particular to complete portions.
Gemäß einer weiteren bevorzugten Ausführungsform wird eine unvollständige Portion, eine Schlechtportion, mindestens eine Anschnittscheibe und/oder ein Endstück mit einem Auffangmittel aufgefangen, bevor es auf der Unterfolienbahn oder in die Verpackungsmulde abgelegt wird, insbesondere fällt. Alternativ oder zusätzlich gelangen, insbesondere fallen die unvollständige Portion, die Schlechtportion, mindestens eine Anschnittscheibe und/oder das Endstück auf die Unterfolienbahn und/oder in die Verpackungsmulde und werden von dort mit einem Entnahmemittel wieder entnommen. Beispielsweise kann dafür ein Roboter eingesetzt werden, der eine Auffangfläche aufweist, die wahlweise in dem Abwurfbereich stromabwärts von dem Schneidmesser angeordnet wird, um die unvollständige Portion, die Schlechtportion, mindestens eine Anschnittscheibe und/oder ein Endstück aufzufangen. Dieser Roboter kann auch alternativ oder zusätzlich einen Greifer aufweisen, der die unvollständige Portion, die Schlechtportion, mindestens eine Anschnittscheibe und/oder ein Endstück von der Unterfolienbahn oder aus der Verpackungsmulde wieder entnimmt.According to a further preferred embodiment, an incomplete portion, a bad portion, at least one cut slice and/or an end piece is caught with a collecting means before it is deposited, in particular falls, on the bottom film web or into the packaging tray. Alternatively or additionally, the incomplete portion, the bad portion, at least one cut slice and/or the end piece reach, in particular fall, on the bottom film web and/or into the packaging tray and are removed there again using a removal device. For example, a robot can be used for this purpose which has a collecting surface which is optionally arranged in the discharge area downstream of the cutting blade in order to collect the incomplete portion, the bad portion, at least one cut slice and/or an end piece. This robot can also alternatively or additionally have a gripper which removes the incomplete portion, the bad portion, at least one cut slice and/or an end piece from the bottom film web or from the packaging trough.
Es können mehrere Produktscheiben auf einer Unterfolienbahn und/oder in einer Verpackungsmulde als Portion und/oder mehrere Portionen auf einer Unterfolienbahn und/oder in einer Verpackungsmulde abgelegt werden.Several product slices can be placed on a bottom film web and/or in a packaging tray as a portion and/or several portions can be placed on a bottom film web and/or in a packaging tray.
Vorzugsweise werden mehrere Produktscheiben auf der Unterfolienbahn und/oder in einer Verpackungsmulde als Portion abgelegt. Dabei werden die Produktscheiben beispielsweise gestapelt oder geschindelt. Gemäß einer bevorzugten Ausführungsform wird zum Schindeln die Unterfolienbahn und/oder die Verpackungsmulde relativ zu der vorzugsweise stillstehenden Aufschneidevorrichtung bewegt. Alternativ oder zusätzlich wird die Aufschneidevorrichtung zum Schindeln relativ zu der vorzugsweise stillstehenden Unterfolienbahn und/oder der vorzugsweise stillstehenden Verpackungsmulde bewegt. Weiterhin bevorzugt wird der Abstand zwischen der Aufschneidevorrichtung und der Folienbahn und/oder der Verpackungsmulde während der Erstellung einer Portion verändert. Diese bevorzugte Ausführungsform ist insbesondere bei einer gestapelten Verpackung von Vorteil, um sicherzustellen, dass die Flugkurve jeder Lebensmittelscheibe einer Portion immer gleich ist.Preferably, several product slices are placed on the bottom 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 bottom film web and/or the packaging tray is moved relative to the preferably stationary slicing device for shingling. Alternatively or additionally, the slicing device is moved relative to the preferably stationary bottom film web and/or the preferably stationary packaging tray for shingling. Furthermore, the distance between the slicing device and the film web and/or the packaging tray is preferably changed during the creation of a portion. This preferred embodiment is particularly advantageous in the case of stacked packaging in order to ensure that the flight path of each food slice in a portion is always the same.
Gemäß einem weiteren Gegenstand der vorliegenden Offenbarung werden mehrere Portionen auf einer Unterfolienbahn und/oder in einer Verpackungsmulde, d.h. in einer Verpackung angeordnet. Diese können übereinander vor nebeneinander angeordnet werden und gestapelt oder geschindelt sein.According to a further aspect of the present disclosure, several portions are arranged on a bottom film web and/or in a packaging tray, i.e. in a package. These can be arranged one above the other or next to each other and can be stacked or shingled.
Das Schneidmesser der Aufschneidevorrichtung kann während des Weitertransports der Unterfolienbahn oder der Verpackungsmulde Leerschnitte durchführen.The cutting blade of the slitting device can make empty cuts during the further transport of the bottom film web or the packaging tray.
Zum Weitertransport der Verpackungen kann es notwendig sein, dass das Schneidmesser sogenannte Leerschnitte durchführt, während denen das Schneidmesser seine Bewegung, beispielsweise seine Dreh- und/oder Orbitalbewegung durchführt, ohne dass Lebensmittelscheiben von der Produktstange abgetrennt werden. Diese Leerschnitte können dadurch erzielt werden, dass die Produktstange von dem Schneidmesser zurückgezogen und/oder dass das Schneidmesser von dem vorderen Ende des Lebensmittelriegels wegbewegt wird. Dadurch werden während des Weitertransports der Unterfolienbahn oder der Verpackungsmulde keine Scheiben abgeschnitten, die dann zwischengespeichert werden müssten. Dadurch, dass das vordere Ende des Lebensmittelriegels und das Schneidmesser während des Leerschnitts voneinander wegbewegt werden, entstehen auch keine sogenannten Schnipsel d.h. unvollständig abgetrennte Lebensmittelscheiben, die dann auf die Unterfolienbahn bzw. in die Verpackungsmulde fallen würden. Vorzugsweise erfolgt der Weitertransport der Unterfolienbahn oder der Verpackung so schnell, dass sich der Lebensmittelriegel auch nicht so deformieren kann, dass er, trotz Beabstandung des vorderen Endes von dem Schneidmesser, in dieses hineingerät.In order to transport the packaging further, it may be necessary for the cutting knife to make so-called empty cuts, during which the cutting knife performs its movement, for example its rotary and/or orbital movement, without cutting food slices from the product bar. These empty cuts can This can be achieved by pulling the product bar back from the cutting blade and/or by moving the cutting blade away from the front end of the food bar. This means that during the further transport of the bottom film web or the packaging tray, no slices are cut off that would then have to be temporarily stored. Because the front end of the food bar and the cutting blade are moved away from each other during the empty cut, no so-called snippets are created, i.e. incompletely severed food slices that would then fall onto the bottom film web or into the packaging tray. Preferably, the further transport of the bottom film web or the packaging takes place so quickly that the food bar cannot deform to the point where it gets caught in the cutting blade, despite the front end being at a distance from the cutting blade.
Die Unterfolienbahn und/oder eine Verpackungsmulde und die Aufschneidevorrichtung können während des Aufschneidens relativ zueinander bewegt werden.The bottom film web and/or a packaging tray and the slicing device can be moved relative to each other during slicing.
Diese Ausführungsform ist insbesondere zur Herstellung von Portionen auf der Unterfolienbahn oder in der Verpackungsmulde von Vorteil. Die Relativ-Bewegung kann in einer horizontalen und/oder in einer vertikalen Ebene erfolgen.This embodiment is particularly advantageous for producing portions on the bottom film web or in the packaging tray. The relative movement can take place in a horizontal and/or vertical plane.
Die Unterfolienbahn und/oder eine Verpackungsmulde kann zum Befüllen mit mindestens einer Lebensmittelscheibe geneigt werden.The bottom film web and/or a packaging tray can be tilted for filling with at least one food slice.
Bei dieser Ausführungsform wird die Verpackungsmulde zum Befüllen mit mindestens einer Lebensmittelscheibe, vorzugsweise jedoch mit einer Portion, geneigt. Das Einlegen erfolgt in diesem Fall vorzugsweise mit einem Ablagetisch, der vorzugsweise ein Einlegeband aufweist. Durch die Schrägstellung der Verpackung kann die Lebensmittelscheibe oder die Portion sehr einfach und erschütterungsfrei eingelegt werden. Die Neigung erfolgt vorzugsweise um eine besonders bevorzugt horizontale Achse, die ganz besonders bevorzugt quer zur Transportrichtung der Unterfolienbahn oder der Verpackungsmulde ausgerichtet ist.In this embodiment, the packaging tray is tilted for filling with at least one slice of food, but preferably with a portion. In this case, the insertion is preferably carried out using a storage table, which preferably has an insertion belt. The inclination of the packaging means that the slice of food or the portion can be inserted very easily and without vibration. The inclination preferably takes place around a particularly preferably horizontal axis, which is most preferably aligned transversely to the transport direction of the bottom film web or the packaging tray.
Eine Portion, bestehend aus mehreren Produktscheiben, kann während des Aufschneidens oder unmittelbar nach dem Aufschneiden in der Verpackung gewogen werden.A portion consisting of several product slices can be weighed in the packaging during slicing or immediately after slicing.
Im vorliegenden Fall weist die Verpackungsmaschine eine Waage auf, die vorzugsweise unterhalb des Schneidmessers angeordnet ist. Die Lebensmittelscheiben, die in die jeweilige Verpackungsmulde oder auf die Unterfolienbahn fallen, werden sofort gewogen. Dadurch kann bereits vor Ort sichergestellt werden, dass die jeweilige Verpackung das geforderte SOLL-Gewicht aufweist. Für den Fall, dass das IST-Gewicht zu gering ist, wird noch eine oder mehrere Produktscheiben abgeschnitten und auf die Unterfolienbahn oder in die Verpackungsmulde gelegt. Für den Fall, dass das IST-Gewicht zu hoch ist, wird vorzugsweise so verfahren, dass sich die Steuerung der Maschine bzw. des Systems die betroffene Verpackung merkt und diese nach dem in der Schneidstation durchgeführten Vereinzeln der Verpackung aus dem Prozess ausschleust oder der Verpackung eine oder mehrere Lebensmittelscheiben entnommen werden. Besonders bevorzugt wird bereits während des Einlegens der einzelnen Scheiben Prozess begleitend gewogen und kurz vor Erreichen des SOLL-Gewichts über Prognoserechnungen das SOLL-Gewicht besonders zielsicher erreicht, also vor allem übergewichtige Verpackungen mit besonders hoher Wahrscheinlichkeit vermieden.In this case, the packaging machine has a scale, which is preferably arranged below the cutting blade. The food slices that fall into the respective packaging trough or onto the bottom film web are immediately weighed. it can be ensured on site that the respective packaging has the required TARGET weight. If the ACTUAL weight is too low, one or more product slices are cut off and placed on the bottom film web or in the packaging trough. If the ACTUAL weight is too high, the preferred procedure is for the machine or system control to remember the affected packaging and, after the packaging has been separated in the cutting station, to eject it from the process or for one or more food slices to be removed from the packaging. It is particularly preferred to weigh the individual slices during the process and, shortly before the TARGET weight is reached, to use forecast calculations to achieve the TARGET weight particularly accurately, thus avoiding overweight packaging with a particularly high degree of probability.
Die Aufschneidevorrichtung kann einen Vorschub für die Produktstange und ein sich bewegendes, insbesondere rotierendes, Schneidmesser aufweisen, das Produktscheiben von dem Produktriegel abschneidet, wobei die Bewegung des Vorschubs und/oder des Schneidmessers in Abhängigkeit des Vorschubs der Unterfolienbahn und/oder der Verpackungsmulde gesteuert wird.The slicing device can have a feed for the product bar and a moving, in particular rotating, cutting knife which cuts product slices from the product bar, wherein the movement of the feed and/or the cutting knife is controlled as a function of the feed of the bottom film web and/or the packaging tray.
Bei diesem Gegenstand der vorliegenden Offenbarung weist die Aufschneidevorrichtung einen Vorschub auf, mit der die Produktstange in Richtung des Schneidmessers bewegt wird. Des Weiteren weist die Aufschneidevorrichtung ein sich bewegendes, vorzugsweise rotierendes, Schneidmesser auf, das Produktscheiben von dem vorderen Ende des Produktriegels abschneidet. Zur Portionierung bzw. zum Weitertransport der Verpackungen kann es notwendig sein, dass das Schneidmesser sogenannte Leerschnitte durchführt, während der das Schneidmesser seine Bewegung durchführt, ohne dass Lebensmittelscheiben von der Produktstange abgetrennt werden. Diese Leerschnitte können dadurch erzielt werden, dass die Produktstange von dem Schneidmesser zurückgezogen und/oder dass das Schneidmesser von dem vorderen Ende des Lebensmittelriegels wegbewegt wird.In this subject matter of the present disclosure, the slicing device has a feed with which the product bar is moved in the direction of the cutting knife. Furthermore, the slicing device has a moving, preferably rotating, cutting knife that cuts product slices from the front end of the product bar. For portioning or further transport of the packaging, it may be necessary for the cutting knife to carry out so-called empty cuts, during which the cutting knife carries out its movement without food slices being severed from the product bar. These empty cuts can be achieved by pulling the product bar back from the cutting knife and/or by moving the cutting knife away from the front end of the food bar.
Es kann mindestens eine der Bewegungen des Vorschubs und/oder des Schneidmessers in Abhängigkeit des Vorschubs der Unterfolienbahn und/oder der Verpackungsmulde gesteuert werden. Die Verpackungsmaschine hat in dem vorliegenden Fall regelungstechnisch den sogenannten "Lead", d. h. die Bewegungen der Aufschneidevorrichtung folgen Signalen, die von der Verpackungsmaschine generiert werden.At least one of the movements of the feed and/or the cutting knife can be controlled depending on the feed of the bottom film web and/or the packaging tray. In this case, the packaging machine has the so-called "lead" in terms of control technology, ie the movements of the cutting device follow signals generated by the packaging machine.
Offenbart ist auch ein Verfahren, bei dem die Aufschneidevorrichtung einen Vorschub für die Produktstange und ein sich bewegendes, insbesondere rotierendes, Schneidmesser aufweist, das Produktscheiben von dem Produktriegel abschneidet und bei dem der Vorschub der Unterfolienbahn und/oder der Verpackungsmulde in Abhängigkeit der Bewegung des Vorschubs und/oder des Schneidmessers gesteuert wird.Also disclosed is a method in which the slicing device has a feed for the product bar and a moving, in particular rotating, cutting knife which cuts product slices from the product bar and in which the feed of the bottom film web and/or the packaging tray is controlled as a function of the movement of the feed and/or the cutting knife.
Im Wesentlichen kann auf die Ausführung gemäß dem zuletzt beschriebenen Verfahren Bezug genommen werden, wobei es in dem vorliegenden Fall so ist, dass der Vorschub der Unterfolienbahn und/oder der Verpackungsmulde in Abhängigkeit der Bewegung des Vorschubs und/oder des Schneidmessers gesteuert wird. Bei dem vorliegenden Fall hat die Aufschneidevorrichtung den Lead. Dieses Verfahren hat insbesondere dann Vorteil, wenn sogenannte geschindelte Portionen hergestellt werden sollen und die Bewegung der Unterfolienbahn oder der Verpackungsmulde relativ zu dem Schneidmesser durch eine Bewegung der Unterfolienbahn oder der Verpackungsmulde selbst erfolgt.Essentially, reference can be made to the embodiment according to the method described last, whereby in the present case the advance of the bottom film web and/or the packaging tray is controlled depending on the movement of the advance and/or the cutting knife. In the present case, the slicing device has the lead. This method is particularly advantageous when so-called shingled portions are to be produced and the movement of the bottom film web or the packaging tray relative to the cutting knife takes place by a movement of the bottom film web or the packaging tray itself.
Vorzugsweise werden mehrere Produktstangen zumindest zeitweise gleichzeitig, vorzugsweise unabhängig voneinander, aufgeschnitten. Dafür weist die Aufschneidevorrichtung vorzugsweise mehrere sogenannte Vorschub-Trassen auf, entlang derer jeweils eine Produktstange transportiert wird. Bei einer zyklischen Bewegung des Schneidmessers, beispielsweise einer Drehung, werden mehrere Produktscheiben im Wesentlichen gleichzeitig abgeschnitten.Preferably, several product bars are cut open at least at times simultaneously, preferably independently of one another. For this purpose, the slicing device preferably has several so-called feed paths, along each of which a product bar is transported. During a cyclical movement of the cutting blade, for example a rotation, several product slices are cut off essentially simultaneously.
Vorzugsweise ist die Anzahl der Produkte unterschiedlich, insbesondere kleiner oder größer, oder gleich der Anzahl der Spuren der Verpackungsmaschine. Insbesondere wenn die Anzahl der Produktstangen, die gleichzeitig aufgeschnitten werden, kleiner ist als die Anzahl der Spuren, ist vorzugsweise ein Ablagetisch vorgesehen, der insbesondere quer zur Transportrichtung der Unterfolienbahn oder der Verpackungsmulde verschoben werden kann und auf dem eine Anzahl von Portionen, die der Anzahl der Spuren, die bei einem Takt beladen werden, entspricht, abgelegt werden kann, bevor diese in die Verpackungsmulden eingelegt werden. Alternativ werden nicht alle Spuren eines Vorzugs gleichzeitig mit einer Portion befüllt, sondern zumindest teilweise nacheinander. Weiterhin alternativ wird bei einer Umdrehung des Messers nicht von allen in der Aufschneidevorrichtung befindlichen Lebensmittelriegeln eine Scheibe abgeschnitten. Dies wird vorzugsweise insbesondere dann gemacht, wenn die Anzahl der Produkte, der Lebensmittelriegel größer ist als die Anzahl der Spuren der Verpackungsmaschine. Um das Abtrennen einer Lebensmittelscheibe von dem jeweiligen Produkt zu verhindern, kann dieses beispielsweise von der Schneidebene zurückgezogen werden.Preferably, the number of products is different, in particular smaller or larger, or equal to the number of tracks of the packaging machine. In particular, if the number of product bars that are cut open at the same time is smaller than the number of tracks, a storage table is preferably provided, which can be moved in particular transversely to the transport direction of the bottom film web or the packaging trough and on which a number of portions corresponding to the number of tracks that are loaded in one cycle can be placed before they are placed in the packaging troughs. Alternatively, not all tracks of a product are filled with a portion at the same time, but at least partially one after the other. Alternatively, not all food bars in the slicing device are cut off a slice when the blade is rotated. This is preferably done in particular when the number of products, the food bars, is larger than the number of tracks of the packaging machine. To prevent a food slice from being separated from the respective product, the product can be withdrawn from the cutting plane, for example.
Vorzugsweise wird bei dem Verfahren ein Ablagetisch zur Anpassung der gleichzeitig abgeschnittenen Produktstangen an die Anzahl der Spuren eingesetzt. Der Fachmann versteht, dass dies natürlich auch zutrifft, wenn nur eine Produktstange aufgeschnitten wird und die Anzahl der Spuren und/oder die Anzahl der Portionen pro Spur und Takt größer als 1 ist.Preferably, the method uses a storage table to adjust the number of product bars cut off at the same time to the number of tracks. The person skilled in the art will understand that this naturally also applies if only one product bar is cut open and the number of tracks and/or the number of portions per track and cycle is greater than 1.
In einer bevorzugten Ausführungsform werden unterschiedliche Produktstangen aufgeschnitten. Ganz besonders bevorzugt weist jede Portion Produktscheiben von unterschiedlichen Produktstangen auf. Dies kann beispielsweise dadurch erreicht werden, dass während des Aufschneidens einer Portion ein Ablagetisch so bewegt wird, dass die jeweilige Portion in wechselnden Flugbahnen der Lebensmittelscheiben des jeweiligen Lebensmittels angeordnet wird.In a preferred embodiment, different product bars are cut open. Most preferably, each portion has product slices from different product bars. This can be achieved, for example, by moving a storage table while a portion is being cut open so that the respective portion is arranged in alternating trajectories of the food slices of the respective food.

Die zu diesem Gegenstand der vorliegenden Erfindung gemachte Offenbarung gilt für die anderen Gegenstände der vorliegenden Erfindung gleichermaßen und umgekehrt.The disclosure made with respect to this subject matter of the present invention applies equally to the other subject matters of the present invention and vice versa.
Die vorliegende Erfindung betrifft eine Verpackungsmaschine zum Verpacken von Produktscheiben mit einer Mehrzahl von Arbeitsstationen, beispielsweise einer Formstation, in der Verpackungsmulden in eine Unterfolienbahn eingeformt, beispielsweise tiefgezogen werden, gegebenenfalls eine Einlegestation, in der die Produktscheiben in die Verpackungsmulden gelegt werden, eine Siegelstation, in der eine Deckelfolie an die Unterfolienbahn gesiegelt wird, um die befüllten Verpackungen hermetisch abzuschließen sowie vorzugsweise eine Schneidstation, in der die Verpackungen vereinzelt werden.The present invention relates to a packaging machine for packaging product slices with a plurality of work stations, for example a forming station in which packaging troughs are formed, for example deep-drawn, into a bottom film web, optionally an insertion station in which the product slices are placed in the packaging troughs, a sealing station in which a lid film is sealed to the bottom film web in order to hermetically seal the filled packages, and preferably a cutting station in which the packages are separated.
Erfindungsgemäß weist diese Verpackungsmaschine nun zusätzlich noch eine Aufschneidemaschine auf, mit der eine Produktstange, die auch Produktlaib genannt wird, in eine Vielzahl von Produktscheiben geteilt wird. Diese Produktscheiben werden sodann in Verpackungen verpackt. Erfindungsgemäß ist die Aufschneidevorrichtung im Bereich der sogenannten Einlegestation vorgesehen. Besonders bevorzugt befindet sie sich oberhalb der Einlegestation, so dass die abgeschnittenen Lebensmittelscheiben auf die Unterfolienbahn oder in die Verpackungsmulde fallen.According to the invention, this packaging machine now also has a slicing machine with which a product bar, also called a product loaf, is divided into a large number of product slices. These product slices are then packed in packaging. According to the invention, the slicing device is provided in the area of the so-called insertion station. It is particularly preferably located above the insertion station so that the cut food slices fall onto the bottom film web or into the packaging trough.
Vorzugsweise weisen die Verpackungsmaschine und die Aufschneidevorrichtung einen gemeinsamen Rahmen auf. Weiterhin bevorzugt weist die Aufschneidevorrichtung Mittel auf, mittels derer die Unterfolienbahn und/oder die Verpackungsmulden entlang der Verpackungsmaschine geführt und/oder transportiert werden. Diese Mittel können sich in zwei entgegengesetzte Richtungen bewegen, um beispielsweise geschindelte Portionen zu erzeugen.Preferably, the packaging machine and the slicing device have a common frame. Furthermore, the slicing device preferably has means by means of which the bottom film web and/or the packaging troughs are guided and/or transported along the packaging machine. These means can move in two opposite directions in order to produce shingled portions, for example.
Erfindungsgemäß ist die Verpackungsmaschine ein sogenannter Tray-Sealer, bei dem vorgefertigte einzelne Verpackungsmulden mit einem Verpackungsgut befüllt werden und diese Verpackungsmulden abschließend mit einer Deckelfolie verschlossen werden. Die Verpackungsmulden werden gestapelt an die Verpackungsmaschine geliefert, so dass der Tray-Sealer eine sogenannte Vereinzelungsstation aufweist, in der die Verpackungsmulden entstapelt, d. h. vereinzelt werden. Erfindungsgemäß ist die Aufschneidevorrichtung stromabwärts von der Verpackungsmuldenvereinzelungsstation und stromaufwärts von einer Siegelstation, in der eine Deckelfolie an die Verpackungsmulde gesiegelt wird, angesiedelt.According to the invention, the packaging machine is a so-called tray sealer, in which prefabricated individual packaging trays are filled with a packaged product and these packaging trays are then sealed with a cover film. The packaging trays are delivered to the packaging machine in stacks, so that the tray sealer has a so-called separating station in which the packaging trays are unstacked, i.e. separated. According to the invention, the cutting device is located downstream of the packaging tray separating station and upstream of a sealing station in which a cover film is sealed to the packaging tray.
Vorzugsweise wird beim Tray-Sealer der Abstand zwischen zwei Verpackungsmulden stromaufwärts von der Aufschneidevorrichtung auf ein gewünschtes Maß gebracht. Alternativ oder zusätzlich weist die Verpackungsmaschine Mittel auf, mittels derer feststellbar ist, wo sich die jeweilige Verpackungsmulde in der Verpackungsmaschine befindet, sodass deren Transport so gesteuert oder geregelt werden kann, dass sich diese zum Beladen genau unterhalb der Flugkurve der Lebensmittelscheiben befindet und/oder im Ablagebereich eines eventuell vorhandenen Ablagetisches.Preferably, in the tray sealer, the distance between two packaging troughs upstream of the slicing device is adjusted to a desired size. Alternatively or additionally, the packaging machine has means by means of which it is possible to determine where the respective packaging trough is located in the packaging machine, so that its transport can be controlled or regulated in such a way that it is located exactly below the flight path of the food slices for loading and/or in the deposit area of a deposit table, if present.
Weiterhin offenbart ist eine Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben, die ein Mittel zum Führen und/oder Transportieren der Unterfolie und/oder einer Verpackungsmulde aufweist.Furthermore, a slicing device for slicing a product bar into product slices is disclosed, which has a means for guiding and/or transporting the bottom film and/or a packaging tray.
Ein weiterer offenbarter Gegenstand ist eine Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben, die eine Ausnehmung aufweist, durch die eine Verpackungsmaschine hindurchführbar ist.Another disclosed subject matter is a slicing device for slicing a product bar into product slices, which has a recess through which a packaging machine can be passed.
Bei dieser Ausführungsform weist die Aufschneidevorrichtung einen Rahmen mit einer Ausnehmung auf, die so groß ist, dass die Verpackungsmaschine hindurchgeführt werden kann. Dadurch kann die Aufschneidevorrichtung beispielsweise vom einem Ende der Verpackungsmaschine auf die Verpackungsmaschine aufgeschoben und dann entlang oder entgegen der Transportrichtung der Unterfolienbahn und/oder der Verpackungsmulde entlang der Verpackungsmaschine verschoben werden, bis die Aufschneidevorrichtung in der gewünschten Position ist. Diese Position kann wahlweise verändert werden. Zur Reinigung der Verpackungsmaschine und/oder der Aufschneidevorrichtung kann die Aufschneidevorrichtung relativ zu der Verpackungsmaschine verschoben oder von der Verpackungsmaschine entfernt werden. Bei einer weiteren Ausführungsform ist die Aufschneidevorrichtung zumindest teilweise weg- und/oder aufschwenkbar, vorzugsweise hochschwenkbar gestaltet, beispielsweise um die Reinigung der Verpackungsmaschine und/oder der Aufschneidevorrichtung zu ermöglichen oder zu erleichtern.In this embodiment, the slicing device has a frame with a recess that is large enough for the packaging machine to be guided through. This allows the slicing device to be pushed onto the packaging machine, for example, from one end of the packaging machine and then along or against the transport direction of the bottom film web and/or the packaging tray. be moved along the packaging machine until the slicing device is in the desired position. This position can be changed as desired. To clean the packaging machine and/or the slicing device, the slicing device can be moved relative to the packaging machine or removed from the packaging machine. In a further embodiment, the slicing device is designed to be at least partially pivotable away and/or open, preferably pivotable up, for example to enable or facilitate cleaning of the packaging machine and/or the slicing device.
Erfindungsgemäß weißt die Verpackungsmaschine ein Mittel auf, das verhindert, dass Produktpartikel in die Verpackung gelangen.According to the invention, the packaging machine has a means that prevents product particles from getting into the packaging.
Beim Aufschneiden von Produktlaiben kommt es immer wieder vor, dass das Messer Produktpartikel von dem Produktlaib abreißt. Die Aufschneidevorrichtung und/oder die erfindungsgemäße Verpackungsmaschine weist nun mindestens ein Mittel auf, das verhindert, dass derartige Partikel in die Verpackung gelangen. Beispielsweise handelt es sich bei dem Mittel um ein Blech oder ein Band, das im Bereich des Schneidmessers, vorzugsweise unterhalb des Schneidmessers und besonders bevorzugt zumindest teilweise oberhalb der Unterfolienbahn oder der Verpackungsmulde, angeordnet wird und dadurch verhindert, dass Produktpartikel in die Verpackung gelangen. Bei dem Mittel kann es sich jedoch auch um einen Gas-, insbesondere Luftstrom, handeln, der beispielsweise die Partikel direkt bei ihrer Entstehung oder von der Verpackungsmulde absaugt und/oder wegbläst. Alternativ oder zusätzlich handelt es sich bei dem Mittel um ein Mittel, das beispielsweise eine elektrische Ladung generiert, die die Produktpartikel anzieht oder abstößt und dadurch von der Verpackungsmulde fernhält.When slicing product loaves, it often happens that the knife tears product particles off the product loaf. The slicing device and/or the packaging machine according to the invention now has at least one means that prevents such particles from getting into the packaging. For example, the means is a sheet or a band that is arranged in the area of the cutting knife, preferably below the cutting knife and particularly preferably at least partially above the bottom film web or the packaging tray, and thereby prevents product particles from getting into the packaging. However, the means can also be a gas, in particular air, stream that, for example, sucks and/or blows away the particles as they are formed or from the packaging tray. Alternatively or additionally, the means is a means that, for example, generates an electrical charge that attracts or repels the product particles and thus keeps them away from the packaging tray.
Ein weiterer offenbarter Gegenstand ist eine Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben, die einen Ablagetisch aufweist, der zusätzlich ein Einleger ist und der die Produktscheiben und/oder Portionen auf eine Unterfolienbahn oder in eine Verpackungsmulde legt.Another disclosed subject matter is a slicing device for slicing a product bar into product slices, which has a deposit table which is additionally a feeder and which places the product slices and/or portions on a bottom film web or in a packaging tray.
Bei dieser Ausführungsform weist die Aufschneidevorrichtung einen Ablagetisch auf, der vorzugsweise unterhalb des Schneidmessers vorgesehen ist und auf den die Lebensmittelscheiben nach dem Abschneiden fallen. Dieser Ablagetisch ist zusätzlich ein Einleger, der die Produktscheiben oder Portionen auf eine Unterfolienbahn oder in eine Verpackungsmulde legt oder abwirft. Dafür ist der Ablagetisch vorzugsweise mit mindestens einem, besonders bevorzugt mit mehreren, Endlos-Bändern versehen, die, nachdem beispielsweise eine oder mehrere Portionen auf dem Ablagetisch komplettiert worden sind, diese auf die Unterfolienbahn oder in eine Verpackungsmulde legen. Die Endlosbänder können gemeinsam oder unabhängig voneinander angetrieben werden.In this embodiment, the slicing device has a deposit table, which is preferably provided below the cutting blade and onto which the food slices fall after cutting. This deposit table is also a feeder, which places or deposits the product slices or portions onto a bottom film web or into a packaging tray. For this purpose, the deposit table is preferably provided with at least one, particularly preferably with several, endless belts, which, after For example, once one or more portions have been completed on the storage table, place them on the bottom film track or in a packaging tray. The endless belts can be driven together or independently of one another.
Vorzugsweise ist der Ablagetisch als sogenanntes Shuttle-Band ausgeführt. Bei einem Shuttle-Band handelt es sich um ein Endlos-Band, das eine schnell rückziehbare vordere Kante aufweist, die betätigt wird, während das Endlosband vorzugsweise stillsteht. Dadurch fallen die Produktscheiben oder Portionen im Wesentlichen senkrecht auf die Unterfolie oder in die Verpackungsmulde.The deposit table is preferably designed as a so-called shuttle belt. A shuttle belt is an endless belt that has a quickly retractable front edge that is actuated while the endless belt is preferably stationary. This causes the product slices or portions to fall essentially vertically onto the bottom film or into the packaging trough.
Vorzugsweise ist der Ablagetisch in mindestens einer Ebene in eine oder mehrere Raumrichtungen, die besonders bevorzugt parallel oder senkrecht zueinander angeordnet sind, bewegbar. Beispielsweise ist der Tisch horizontal in einer Ebene in mindestens einer, vorzugsweise zwei, oder mehr Raumrichtungen bewegbar. Alternativ oder zusätzlich ist der Ablagetisch höhenverstellbar, d. h. er kann in Richtung des Schneidmessers und davon weg höhenverstellt werden. Dadurch kann der Ablagetisch beispielsweise so zur Produktstange und/oder zum Schneidmesser vertikal beabstandet werden, dass jede Produktscheibe dieselbe oder eine gezielt andere Fallhöhe hat, um beispielsweise ein symmetrisches Ablegemuster der Produktscheiben zu erreichen. Besonders bevorzugt wird der Tisch und/oder die damit versehenen Bänder vor dem Abschneiden jeder Produktscheibe um eine definierte Wegstrecke in beispielsweise horizontaler Richtung verschoben, um ein ausgeprägtes Schindelmuster oder, beim Verschieben in entgegengesetzter Richtung beispielsweise ein besonders geraden Scheibenstapel zu erreichen.Preferably, the storage table is movable in at least one plane in one or more spatial directions, which are particularly preferably arranged parallel or perpendicular to one another. For example, the table is movable horizontally in a plane in at least one, preferably two, or more spatial directions. Alternatively or additionally, the storage table is height-adjustable, i.e. it can be adjusted in height towards the cutting blade and away from it. This means that the storage table can be vertically spaced from the product bar and/or the cutting blade, for example, so that each product slice has the same or a deliberately different drop height, for example to achieve a symmetrical deposit pattern of the product slices. Particularly preferably, the table and/or the belts provided with it are moved by a defined distance in, for example, a horizontal direction before each product slice is cut, in order to achieve a pronounced shingle pattern or, when moved in the opposite direction, for example a particularly straight stack of slices.
Alternativ oder zusätzlich ist der Ablagetisch um eine horizontale Achse drehbar vorgesehen. Dadurch kann der Ablagetisch beispielsweise nach Komplettierung einer Portion geneigt werden, was das Ablegen auf einer Unterfolienbahn oder das Einlegen in eine Verpackungsmulde erleichtert. Alternativ oder zusätzlich ist der Ablagetisch um eine vertikale Achse drehbar vorgesehen, um beispielsweise kreisförmige Portionen zu erzeugen.Alternatively or additionally, the storage table can be rotated around a horizontal axis. This means that the storage table can be tilted, for example, after a portion has been completed, which makes it easier to place it on a bottom film web or place it in a packaging tray. Alternatively or additionally, the storage table can be rotated around a vertical axis, for example to produce circular portions.
In einer bevorzugten Ausführungsform ist der Ablagetisch als Waage ausgeführt, sodass während des Aufschneidens einer Portion festgestellt werden kann, ob diese das gewünschte Mindestgewicht aufweist.In a preferred embodiment, the storage table is designed as a scale so that while a portion is being cut it can be determined whether it has the desired minimum weight.
Ein weiterer offenbarter Gegenstand ist eine Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben oder eine Verpackungsmaschine, jeweils insbesondere wie oben beschrieben, wobei sie einen Sensor aufweist, der mindestens ein Qualitätsmerkmal der Produktscheiben und/oder der Portionen erfasst.Another disclosed subject matter is a slicing device for slicing a product bar into product slices or a packaging machine, each in particular as described above, wherein it comprises a sensor which detects at least one quality feature of the product slices and/or the portions.

Das Signal des Sensors wird vorzugsweise an eine Steuerung weitergeleitet, die Scheiben mit einer mangelnden Qualität beispielsweise aussortiert. Dafür können der Ablagetisch, das Auffangmittel und/oder ein Entnahmemittel eingesetzt werden. Alternativ oder zusätzlich können Packungen mit einem mangelhaften Produkt, insbesondere nach deren Verschluss mit einer Deckelfolie aussortiert werden.A quality feature is, for example, the temperature, the color, the slice shape and/or the slice size, the portion shape and/or the portion size, fat content, so-called "blood spots", too few or too many holes, especially in cheese, and/or the presence of foreign bodies. The sensor signal is preferably forwarded to a control system, which sorts out slices of poor quality, for example. The storage table, the collecting device and/or a removal device can be used for this. Alternatively or additionally, packages with a defective product can be sorted out, especially after they have been sealed with a lid film.
Ein weiterer offenbarter Gegenstand ist eine Aufschneidevorrichtung zum Aufschneiden einer Produktstange in Produktscheiben und/oder eine Verpackungsmaschine, jeweils insbesondere wie oben beschrieben, die ein Bestrahlmittel aufweist, das vorzugsweise den Anschnitt der Produktstange und/oder die abgeschnittene Produktscheibe und/oder die aufgeschnittene Portion bestrahlt und dabei zumindest teilweise desinfiziert.A further disclosed subject matter is a slicing device for slicing a product bar into product slices and/or a packaging machine, in each case in particular as described above, which has an irradiation means which preferably irradiates the cut portion of the product bar and/or the cut product slice and/or the sliced portion and thereby at least partially disinfects it.

Diese Ausführungsform der Aufschneidevorrichtung hat den Vorteil, dass die Haltbarkeit der Produktscheiben in den hergestellten Verpackungen erhöht wird.This design of the slicing device has the advantage that the shelf life of the product slices in the produced packaging is increased.
Vorzugsweise wird die abgeschnittene Produktscheibe auf beiden Schnittflächen bestrahlt. Vorzugsweise weist die Aufschneidevorrichtung oder die Verpackungsmaschine ein Mittel auf, mit denen die Strahlen des Bestrahlmittels gezielt auf den Anschnitt und/oder die abgeschnittene Produktscheibe und/oder die aufgeschnittene Portion gelenkt werden.Preferably, the cut product slice is irradiated on both cut surfaces. Preferably, the slicing device or the packaging machine has a means by which the rays of the irradiation agent are directed specifically onto the cut and/or the cut product slice and/or the sliced portion.
Ein weiterer offenbarter Gegenstand ist eine Verpackungsmaschine oder eine Aufschneidevorrichtung, die ein Mittel aufweist, um die Lage der Unterfolienbahn und/oder einer Verpackungsmulde und der Aufschneidevorrichtung relativ zueinander zu verändern.Another disclosed subject matter is a packaging machine or a slicing device which has a means for changing the position of the bottom film web and/or a packaging tray and the slicing device relative to each other.
Beispielsweise kann dadurch der vertikale Abstand zwischen dem Schneidmesser und der Transportebene der Unterfolienbahn und/oder einer Verpackungsmulde verändert werden.For example, the vertical distance between the cutting knife and the transport plane of the bottom film web and/or a packaging tray can be changed.
Alternativ oder zusätzlich wird der Winkel, in dem die Aufschneidevorrichtung, insbesondere das Schneidmesser, und/oder die Vorschubeinheit der Produktstange relativ zu der Transportebene der Unterfolienbahn oder der Verpackungsmulde angeordnet sind, verändert.Alternatively or additionally, the angle at which the slicing device, in particular the cutting knife, and/or the feed unit of the product bar are arranged relative to the transport plane of the bottom film web or the packaging tray is changed.
Durch die oben genannten Maßnahmen kann beispielsweise die Fallhöhe, der Fallwinkel oder die Fallkurve bezogen auf die Ebene, in der die Unterfolienbahn oder die Verpackung geführt wird, verändert werden.By means of the measures mentioned above, for example, the fall height, the fall angle or the fall curve can be changed in relation to the plane in which the bottom film web or the packaging is guided.
Ein weiterer Gegenstand der vorliegenden Erfindung ist ein System gemäß Patentanspruch 3.Another object of the present invention is a system according to claim 3.
Ein weiterer offenbarter Gegenstand ist eine Aufschneidevorrichtung und/oder eine Verpackungsmaschine, jeweils insbesondere wie oben beschrieben, bei dem/der der Bereich des Messers und/oder der Abwurfbereich der abgeschnittenen Lebensmittelscheibe und/oder der Einlegebereich mit Unterdruck und/oder einer veränderten Atmosphäre versehen ist.A further disclosed subject matter is a slicing device and/or a packaging machine, in each case in particular as described above, in which the region of the knife and/or the discharge region of the cut-off food slice and/or the insertion region is provided with negative pressure and/or a modified atmosphere.
Gemäß dieses Gegenstands erfolgt das Abschneiden und/oder Abwerfen und/oder Einlegen der jeweiligen Lebensmittelscheibe unter einer geänderten Atmosphäre im Vergleich zu der Umgebungsatmosphäre. Vorzugsweise liegt diese veränderte Atmosphäre auch im Bereich der Unterfolienbahn oder der Verpackungsmulde vor. Beispielsweise kann das Messer und/oder der Abwurfbereich und/oder der Einlegebereich zumindest teilweise gekapselt sein und unter Unterdruck stehen und/oder es kann in diese Kapselung ein Gas mit einer anderen Zusammensetzung als Luft eingeführt werden.According to this subject matter, the cutting and/or ejection and/or insertion of the respective food slice takes place under a changed atmosphere compared to the ambient atmosphere.
