Definitions

  • the invention relates to a method according to the preambles of claims 1 and 3 and a cutting machine according to the preamble of claim 7.
  • Food slicing machines in particular bread slicing machines, are generically differentiated into those intended for industrial use and those which are suitable for being set up in retail outlets for slicing up foodstuffs supplied there such as loaves of bread by inserting them into sliced packages, be it by the sales staff immediately prior to the sale or be it by the buyer after the sale.
  • the latter type of cutting machines must be designed as compact as possible because of the usually limited space, and they must above all be encapsulated so that when operating the cutting machine as low as possible, better no risk of injury exists.
  • a typical bread slicer for this application is the DE 10 2008 012 858 B3 refer to.
  • Such bread slicing machines have a machine frame surrounded by a housing. At the top is a cover. After opening the cover, a loaf of bread can be placed in a horizontally or obliquely downward extending, straight-line bread transport channel.
  • the bread transport channel begins with a loaf tray and continues in Brottransportides after a cutting device in an aligned subsequent Brotusionnseefach.
  • the cutting device may comprise a sickle knife or a circular saw-like knife, which is movable into a cutting position from an initial position in which it does not protrude into the bread transport channel.
  • an advancing device having a feed carriage projecting into the bread transport channel and movable via an engine and transmission between an initial position remote from the cutter and an end position near the cutter.
  • the feed slide has a contact plate, via which the inserted loaf of bread is advanced by the adjustable thickness of a slice of bread when carrying out the cutting operation.
  • a slice of bread is cut off the loaf of bread with the help of a knife. This is repeated in the cycle of the disc until the loaf of bread is completely divided into slices of bread to form a bread slice package. It is then in the bread slice receiving compartment and can be removed from there after opening a cover. Thereafter, it can be wrapped in a packaging bag of plastic film material.
  • a bread slicer in which in the area of the bread slice receiving compartment packaging bags are kept ready, which can be inflated by means of a blower. Thereafter, the bread slice package can be manually or mechanically inserted into the packaging bag. In the latter case, it no longer requires special handling for coating the packaging bag.
  • a disadvantage of this type of cutting machine is that suitable packaging bags must be provided, and that the function was not secured in mechanical transport of the disc pack in the packaging bag.
  • a packaging plant in which bread slices are fed via a conveyor belt to a packing station, in which a packaging film web of weldable film material is stretched between two roll-shaped storage media.
  • the bread slice package is pushed with the bread slices one above the other transversely to the packaging film web under formation of a package receiving compartment in the packaging film web.
  • the packaging film web is welded to the front and back.
  • the bread slice package is spent with the still open on the sides of the package on a moving conveyor belt in a further station, where the still open side edges of the packaging film web are welded and at the same time also evacuated from the packaging interior are evacuated.
  • this plant is designed with its components for use in the industrial sector, ie the industrial bread making, and thus unsuitable for installation in retail outlets.
  • the invention has for its object to provide a method for packaging cut slice packages in a cutting machine, which ensures a secure packaging of the disc pack. Another object is to design a cutting machine with a packaging station such that the packaging process automatically and nevertheless reliably.
  • the basic idea of the invention is thus not to provide a finished packaging bag within the cutting machine, but to produce the packaging bag during the packaging process by wrapping the package of film from a packaging film web of weldable film material and then welding it on at least two sides in such a way the disc package is after this manufacturing process in a packaging bag, one side of which is open, which can then be closed, for example by means of brackets or by another welding process.
  • the advantage of this method is that only simple film webs of weldable material, such as a solid plastic film or a plastic-coated film of paper or metal, must be kept ready, which are easy to procure and handle and secure wrapping the disk package largely independent of its size.
  • the welding can be carried out by direct thermal action or by means of ultrasound action, wherein the plastic material melts.
  • the method according to the invention is suitable not only for cutting and packaging bread, but also for other, similarly shaped, i. string or loaf-shaped foods having such a consistency that they can be processed according to the method of the invention.
  • the cover can be opened, and it can then be removed from the packaged disc package.
  • the packaging bag formed from the packaging film web and still connected to it tears off in the area between the two side welds. For tearing only a small amount of force is required because only very thin foils are required for the packaging of the disc package.
  • the package receiving compartment is formed by the disk package by its movement from the starting position into the packaging position.
  • the disk package itself is used to form the package receiving compartment, ie the method steps according to the aforementioned features c) and d) merge into one operation. This is done by pushing the disk package in the clamped part of the packaging film web, and preferably so far until the disk package is wrapped on three sides of its circumference of the packaging film web. Then the open side can be merged the packaging film web and then producing the side welds are closed in the circumferential direction.
  • the package receiving tray is formed by appropriate molding tools and then the disc package is moved into the receiving compartment, the above-mentioned features c) and d) thus take place successively.
  • the packaging film web is stretched so that it forms a flat bearing surface, and that the disk package is pushed perpendicular to the cutting planes on the support surface to the starting position.
  • the package receiving tray may be formed by a specialist former such that a package receiving tray is formed around the disk package.
  • the disk package is not moved horizontally in the package receiving compartment, but obliquely downward.
  • the packaging film web is first also formed into a package receiving tray before the disk package is inserted into the package receiving tray.
  • the insertion does not take place in this case - as in the method described above - transverse to the packaging film web, but longitudinally thereto, ie limited by one of the lateral, of one of the side edges of the packaging film web Opening the package receiving compartment.
  • This variant has the advantage that no change in direction has to be made for the movement of the disk package, but rather the possibility exists of moving the disk package formed by the cutting process, in continuation of the movement through the cutting station and in a straight line, into the previously formed package receiving compartment, preferably with the transport device, with the help of which the food has already been pushed through the cutting station.
  • the packaging film web is expedient for the packaging film web to be unwound as a storage store during the shaping of the package receiving compartment by two supply rolls. These should be synchronized in such a way that the packaging film web is drawn off from the two storage reservoirs by the same amount during the shaping of the package receiving compartment and during the bringing together for the production of the side welds. This has the advantage that the stock of packaging film web is always the same in both stores.
  • the thus designed cutting machine realizes the basic idea of realizing the method described above with the aid of a film web tensioning device, a transport device, a shaping device, a conveyor device and a welding device, ie automatically packaging a disk package within the cutting machine and thus without access from the outside, by wrapping the disk pack of a packaging film web and then the open sides are welded so that the disc package is wrapped by a packaging material consisting of film material bag.
  • the packaging bag may be open on one side, or it may also be provided there a weld, if the welding device is designed accordingly. It is particularly preferred if the process of cutting and packaging of fully automatic, for example, after operating a start button or closing a cover, happens, so that further operation by the operator is not required. This does not exclude that several buttons must be operated to operate the cutting machine.
  • the transport device is designed and controlled such that the disk package is moved to a starting position transversely to the clamped part of the packaging film web, and that the conveyor is designed and controlled so that it moves the disk package from the starting position pushes the clamped part of the packaging film web to form the package receiving compartment, so that the conveyor simultaneously forms the tray forming device.
  • This design of the cutting machine or its packaging station has the advantage that it requires for the formation of the package receiving compartment only a simple conveyor, for example in the form of a slide, which is suitable to push the disk located in the starting position in the packaging film web and thereby form the package receiving compartment ,
  • the shed forming device may comprise a motor-operated shed forming tool which is movable between a rest position and an end position, wherein upon movement into the end position it forms a package receiving compartment in the clamped part of the packaging film web.
  • the package receiving compartment can be formed independently of the shape of the disk package such that the disk package can be inserted into the previously formed package receiving compartment.
  • An expedient embodiment is that the packaging film web is guided over a bearing surface, which forms the starting position for the disk package, and that in molding the ierefactfach the packaging film web using the then serving as a conveyor molding tool is so deducted on the support surface that on the packaging film web resting disc package taken and added to the package receiving tray.
  • the formation of the package receiving compartment and the introduction of the disc package in that at the same time by movement of the portion of the packaging film web on which the bread slice package rests after shipment to the Ausgans position.
  • the suausform Nurs is designed and controlled such that first the package receiving tray is formed, and that then the conveyor is controlled such that the disk pack is inserted into the package receiving tray.
  • the operations of forming the package receiving compartment on the one hand and the placement of the disk package in the latter on the other hand take place chronologically one after the other.
  • the transport device is designed and controlled such that the disk package is moved to an initial position in front of one of the side edges of the packaging film web, that is not up to the height of the packaging film web transversely thereto. Then, after the package receiving compartment has been formed, the transport device can be controlled such that the disk package is inserted along the packaging film web into the previously formed package receiving compartment and the transport device thereby performs the function of the conveying device. This is particularly useful when a straight transport channel is formed, which extends from the food storage compartment to the packaging station. Of course, there is also the possibility that a separate conveyor is provided in addition to the transport device.
  • the transport device is designed and controlled in such a way that the disk package is moved into a starting position transversely to the clamped part of the packaging film web, and that the conveying device is activated in such a way after the package receiving compartment has been formed, that the disc package from the starting position towards the Packaging film web is inserted into the package receiving tray.
  • the storage devices are designed as supply rolls which are easy to exchange when the packaging film web has been completely removed from them.
  • the storage media should be coupled in such a way that the packaging film web is pulled off during the forming of the package receiving compartment and during the merging for the purpose of producing the side welds in each case by the same amount from the two storage media.
  • the welding device can be designed such that it has at least two welding bars, wherein a welding bar for the production of the side welds and another for the production of the at least one bottom weld are arranged.
  • the welding bars are controlled such that first the side welds and then the bottom weld or bottom welds are made.
  • the transport device has a preferably rectilinear transport channel, along which a slide is guided motor-driven as part of the transport device, which at least between cutting station and packaging station back and forth.
  • the slider is designed and guided so that it first receives the uncut food and in the usual way - for example with the aid of a gripping claw and holding thorns - Fixed, then transported through the cutting station and finally spends the disk package thus formed up in the packaging station and there to the starting position.
  • the cutting machine is encapsulated such that the access to the cutting station and the packaging station is accessible only via at least one cover which is movable between a closed position and an open position.
  • it can be provided over the entire transport channel extending cover, which allows both the removal of the packaged disc pack and the insertion of a new food in the open position.
  • the cover can also be divided into Abdeckhaubenmaschine, for example, such that a first Abdeckhaubenteil makes only the receptacle and a second cover part only the packaging station, the Abdeckhaubenmaschine each can be opened and closed independently.
  • the cover may be associated with a closing sensor, which influences the control device such that the control of the motors for the machining operation is only possible when the cover is in the closed position. This is for the safety of the operators. It is understood that when Abdeckhaubenmaschine are present in the aforementioned sense, a control of the individual parts of the bread slicer should be possible only when both Abdeckhaubenmaschine are in the closed position.
  • the control can then by means of a control button that can be actuated from the outside, but also in such a way that the cutting machine automatically starts to work when the cover - or the cover parts as a whole - has reached its closed position.
  • the cover or its parts by means of a motor between the open position and closed position is movable.
  • the operation is then limited to the operation of a control button.
  • control should be interrupted immediately by the control device when the cover - even if only partially - is opened during the machining process, that is moved out of the closed position.

  • the starting position is not transverse to the clamped-on part of the packaging film web 69, but in the bread transport direction in front of it, outside the region of the packaging film web 69 at a distance from its side edge remote in this view.
  • Shaped form strut 70 is also part of a shed forming device which cooperates with the control device of bread slicer 1.
  • a longitudinal welding bar 74 Adjacent to the upper supply roll 67 there is a longitudinal welding bar 74 which belongs to the welding device and which extends parallel to the packaging film web 79 perpendicular to the plane of the drawing. Not shown is a in the same arrangement as in the embodiment according to the FIGS. 1 and 6 trained transverse welding beam.
  • longitudinal welding bars 74 and transverse welding bars are lowered in the direction of arrow C onto that part of the packaging film web 69 which extends over the top side of the bread transport channel 66.
  • two side welds are generated in the manner already described.
  • a bottom weld is also produced.
  • the bread slice package 72 can be removed, wherein the film is torn off between the two side welds.
  • the bread slice package 72 is then wrapped by a packaging bag, the open end can then be closed with brackets.
  • the formation of the package receiving compartment 73 can already take place during the slicing of the loaf, so that the bread slice package 72 can be transported without interruption from the cutting device to the package receiving compartment 73, thus overriding the starting position described above without stopping.
