Such a cutting device is for example from the DE 10 2007 017 899 A1 known. There, by means of the cutting jet, two regions of the material to be cut, for example of fruit or meat, are separated from one another with different properties, which differ in their structure, their texture, their cell structure, their color and / or their composition. These are, for example, areas of pulp and defects of inferior quality. The cutting path is calculated by means of a control device which comprises an image recognition device and a data processing direction by means of which the different regions to be separated are detected and from which a cutting path is calculated. The cutting path is thus always calculated depending on the nature and the nature of each arranged in the cutting device Schneidgut.

It However, there are applications where it is desirable to Fruits or vegetables in a given shape too regardless of the type and condition of the cutting material is. Of course, this is the case for each Taking into account available material volume, depending on the particular fruit to be cut or each to be cut vegetables or other cutting material is available.

Moderate device The object of the invention is therefore an apparatus and a method to provide the above-mentioned type, which the above thought Take into account.

The Control device operates so, so that a largely arbitrary Geometry for the cutting stock to be obtained as a cutting pattern can be specified without affecting the nature and condition of the cutting material must be respected. This means that too cutting material does not yet have to be known in detail when the controller programmed and set the cutting pattern becomes.

at the cutting jet may be, for example, a high Pressure emitted jet of a cutting fluid, such as water, act. Alternatively, the cutting beam z. B. in the form of a laser beam available. The term high energy cutting jet is so to understand that such a cutting jet is suitable cutting material to cut and cut.

Around the cutting path to the actual size to be able to adjust the material to be cut, it is advantageous if the controller also Includes means for receiving an image of the material to be cut and the Data processing device based on one or more images of Cuttings at least determined its outer contour and the control signal set optionally to the outer contour of the material to be cut. So z. B. one after the other possibly pitted plum and a melon are cut, in each case the same geometry of the preserved fruit pieces only can be obtained in different sizes. The data processing device is then equipped with an image recognition and processing algorithm which generated the Image or its digital data.

It is advantageous if the means for receiving an image of the material to be cut a CMOS sensor or a CCD sensor. In this way can be established techniques for creating digital images be used, reducing the cost of the cutting device on one favorable level can be maintained.

It is favorable if the management device a has in at least two directions movable nozzle, from which the cutting beam can be dispensed. In this case can the cut material during the cutting process largely immobile are held, whereas the nozzle according to the the data processing device calculated cutting path out can be. As a nozzle should here also a laser beam source be understood.

Without however, another degree of freedom of movement is only very simple Cutting curves possible.

It is therefore advantageous if the guide means comprises, through which the material to be cut relative to the cutting beam can be rotated about a rotation axis. This can either be the cutting material twisted or led the cutting beam around the cutting material around become.

It is particularly favorable when the cutting jet in a on a horizontal plane related cutting angle on the material to be cut is deliverable.

If the cutting angle changeable and in particular during the relative movement between material to be cut and cutting beam changeable There are many different cut surfaces be generated.

there it is advantageous if the cutting angle between at least 45 ° and 90 ° is changeable.

The cutting jet is preferably made of egg NEM cutting fluid formed. It is advantageous if the cutting fluid is water, alcohol or a water / alcohol mixture. It may be favorable if the cutting fluid is additionally provided with at least one additive, in particular β-carotene.

alternative It may be beneficial if the cutting beam by a laser beam is formed.

The Possibility of microbial spoilage is already happening limited in the cutting process when the cutting device has a gas-tight cutting space bounded by a housing, which has a shielding gas supply port. about The latter can provide the cutting room with a protective gas such as nitrogen, carbon dioxide or a noble gas are supplied, whereby the cutting process under Protective gas atmosphere can take place.

1 shows cutting material to be cut in the form of a schematically represented apple 10 in a cutting device 18 is arranged for cutting cutting material. If below on the apple 10 This cutting device is referred to 18 includes a gas-tight housing 20 which is a cutting room 22 surrounds. The housing 20 has a feed area on one side 24 on, over which apples 10 in the cutting room 22 of the housing 20 can be introduced. To maintain the gas-tightness of the housing 20 is the feed area 24 designed as lock not interesting here, which is in 1 through the dashed line 26 is indicated.

The feeding area 24 opposite includes the housing 20 a delivery area 28 through which cut apples 10 from the cutting room 22 be delivered. Also the delivery area 28 is to maintain the gas tightness of the housing 20 designed as a lock; this is in 1 by another dashed line 30 indicated.

Between the feed area 24 and the delivery area 28 runs in the cutting room 22 a belt conveyor 32 with a conveyor belt 34 , which is formed in a permeable net-like structure. This has a variety in 2 to be recognized openings 36 on. In the feed area 24 of the housing 20 is a feeding belt conveyor 32a and in the delivery area 28 of the housing 20 is a dispensing belt conveyor 32b arranged.

Below the belt conveyor 32 is a tub 38 provided, the peripheral wall 40 close to the walls of the housing 20 runs.

The housing 20 also has a connector 42 on, over which the cutting room 22 from a not dargestell th inert gas source, a protective gas in the form of nitrogen or carbon dioxide or optionally also a noble gas can be supplied, so that the cutting process in the cutting room 22 of the housing 20 can be carried out under a protective gas atmosphere.

The housing 20 has opposite side walls 44 and 46 (see. 2 ), which are perpendicular to side walls 48 and 50 run, which in turn the feed area 24 or the delivery area 28 exhibit. On the side walls 44 . 46 are slightly above the belt conveyor 32 each a first part 52a and a second part 52b a holder 54 for the apple 10 intended. Every part 52a . 52b includes a stop stamp 56a respectively. 56b , which at the front of a handrail 58a respectively. 58b is arranged. Every handrail 58a . 58b in turn, by means of an associated electric motor 60a respectively. 60b movable in its longitudinal direction and rotatable about its longitudinal axis, which is in 2 indicated by corresponding arrows. The longitudinal axis of the handrails 58a . 58b thus forms the axis of rotation for the apple 10 , In addition, every handrail can 58a . 58b be moved in the vertical direction. The holder 54 stops in the 1 and 2 the Apple 10 ,

In a modification, the handrails can 58a . 58b synchronously along the walls 44 respectively. 46 are moved, which is shown by dashed double arrows. By the handrails 58a . 58b can be synchronized retracted or extended, the apple 10 in the direction between the walls 44 and 46 of the housing 20 be positioned.

Above the feed area 24 and the delivery area 28 is in the cutting room 22 of the housing 20 a nozzle unit 62 intended. This includes one along a guide rod 64 movable housing in both directions 66 , To move the housing 66 on the guide rod 64 this carries an electric motor 68 , In addition, the housing carries 66 a high pressure nozzle 70 , which via a fluid line 72 with a compressor 74 communicates, in turn, via a fluid line 76 is fed from a fluid source, not shown here with a cutting fluid such as water, alcohol or a water / alcohol mixture. In this way, the high pressure nozzle 70 a cutting jet 78 leave, which consists of the corresponding cutting fluid. The cutting jet 78 leaves the high pressure nozzle 70 doing so under such a high pressure that he used to cut each in the cutting device 18 introduced cutting material is suitable.

The high pressure nozzle 70 can by means of the electric motor 68 also be moved so that the cutting beam 78 can run within a cutting cone whose longitudinal axis is vertical. The cutting cone is in 2 through the cutting jet 78 flanking dotted lines indicated and has a cone angle of 90 °. Thus, the cutting beam 78 in a cutting angle of 45 ° to 90 ° relative to the apple, based on a horizontal plane 10 be delivered. In a modification, the cone angle of the cutting cone can also be larger, so that the angle of incidence with respect to a horizontal plane can also be lower and, for example, reaches up to 5 ° or less.

The guide rod 64 on which the nozzle unit 62 is arranged, perpendicular to the walls 48 and 50 of the housing 20 and is at its opposite ends in each case by a guide member 80 respectively. 82 held, which in turn on each of a guide rod 84 respectively. 86 are arranged movable. These are the guide rods 84 . 86 between the walls 44 and 46 of the housing 20 and perpendicular to it, designed as threaded rods, by means of a respective associated electric motor 88 respectively. 90 can be twisted around its longitudinal axis. The guide members 80 . 82 sit with a corresponding thread on the threads of the guide rods 84 . 86 so that they are at a corresponding twisting of the guide rods 84 . 86 drive along this. So that through the guide rod 64 rigidly interconnected guide members 80 and 82 can not tilt, are the electric motors 88 and 90 synchronized accordingly.

The holder 54 for the apple 10 is part of a leadership facility 92 , which also the nozzle unit 62 , the guide rod 64 with the guide members 80 and 82 , the guide rods 84 and 86 and the associated electric motors 86 . 88 and 90 includes. Through the leadership facility 92 is a controlled relative movement between the apple 10 and the cutting jet 78 possible.

On the inside of a blanket 94 of the housing 20 is an image capture unit 96 arranged, which with a CMOS sensor or a CCD sensor 98 works and can take a digital picture. The image capture unit 96 has an in 1 indicated by dotted lines field of view, which is the apple 10 in the holder 54 covers or captures, as it is in 1 is shown.

The image capture unit 96 communicates via a data line 100 with a calculator 102 , which is programmed with an image recognition and processing algorithm. The computer 102 recognizes the outer contour 12 of the apple 10 on the basis of the image acquisition unit 96 transmitted digital image data.

Via a data bus 104 the computer communicates 102 further with a programming unit 106 , by means of which a Benut zer the cutting device 18 can specify a cutting pattern, and based on the predetermined cutting pattern, generates a control signal set for controlling the high-pressure nozzle 70 , The computer 102 transmits the corresponding control signals via the data bus 104 and corresponding data paths, which in the 2 and 3 shown by dashed lines, but not specifically provided with a reference numeral to the electric motors 60a . 60b the holder 54 , to the electric motor 68 the nozzle unit 62 as well as to the electric motors 88 and 90 , These data paths can be bridged by means of data lines or wirelessly. In the latter case, each corresponding transmitter / receiver modules necessary, as they are known in and of themselves.

The cutting device 18 Now works on the example of the apple 10 as follows:
About the feed belt conveyor 32a becomes the apple 10 in the cutting room 22 of the housing 20 promoted. With the belt conveyor 32 becomes the apple 10 like that in the cutting room 22 positioned it between the temples 56a . 56b the holder 54 to come to rest. These are the handrails 58a . 58b initially in the direction of the electric motors 60a respectively. 60b retracted. These are now extended until the stop stamps 56a . 56b each against the apple 10 Press and this thereby in the holder 54 is fixed. If necessary, the so fixed apple 10 be driven slightly vertically upwards, thus allowing an unobstructed rotation or movement of the apple 10 opposite the cutting jet 78 is possible.

About the programming unit 106 becomes the calculator 102 given a free cutting pattern, z. B. a cutting pattern, based on which two comb or rake-like interlocking apple parts are to be obtained, as it is in 3 ge shows is. There is an apple piece with 14 and the other apple part with 16 designated, which have associated cutting surfaces, of which the to be recognized and the apple part 14 associated cutting surface with 14a is designated. Based on this cutting pattern calculates the calculator 102 a cutting path for the cutting jet 78 ,

Now with the image acquisition unit 96 a picture of the apple 10 taken from above. The image capture unit 96 transmits the image data to the computer 102 in which they may be cached. Now calculates the calculator 102 using the image data by means of its image processing algorithm, the outer contour 12 of the apple 10 and compares these with the previously calculated cutting path along which the cutting jet 78 should be led. If the calculated cutting path over the outer contour of the apple 10 protrudes or related to the outer contour of the apple 10 too far inside, calculates the calculator 102 a new cutting path that matches the outer contour of the apple 10 adapted and better uses the available volume.

Now the high pressure nozzle 70 by means of electric motors 88 . 90 and 68 over the guide rods 64 . 82 and 84 on one side of the bracket 54 process and, if required by the cutting path used, the apple 10 by a rotation of the handrails 58a . 58b the holder 54 twisted by a certain angle.

At the in 3 shown cut geometry is no twist of the apple 10 opposite the cutting jet 78 necessary.

To an immediate disintegration of the individual pieces of apple 14 and 16 To prevent, the calculator can 102 Calculate a cutting sequence, in which when starting the in 3 With 108 designated cutting path with the cutting beam 78 connecting webs 110 between the apple parts 14 and 16 persist, of which in 4 only two are provided with reference numerals. This is the cutting beam 78 when driving off the cutting path 108 not continuously activated, but will along the appropriate cutting path sections, where de apple 14 should not be cut, disabled.

The connecting bridges 110 keep the apple parts 14 and 16 together, however, are so thin that they are destroyed at a low force, the z. B. is exercised when the two apple pieces 14 and 16 to be pulled apart by hand.

In 5 Another way is shown with which an instant breakup of apple pieces 14 and 16 can be prevented. There was a modified cutting track 112 with the cutting jet 78 departed, at which at vertices 114 undercuts 116 remain.

In 6 is an example of the result of another free via the programming unit 106 input cutting pattern for cutting an apple 10a shown. As can be seen there, the apple 10a several cylinders 118a to 118g cut out, which are still shown in some sections pushed together. These are the outer cylinders 118a to 118f formed as a hollow cylinder. The outer and inner surfaces of the respective cylinders 118a to 118g each form the resulting cutting surfaces.

In 7 is another result of a free through the programming unit 106 entered cutting pattern for cutting a zucchini 120 (or a cucumber) shown. The zucchini 120 became two helical and interlocking zucchini pieces 122 and 124 cut. The mutually complementary cutting surfaces of these Zuchchiniteile 122 and 124 bear the reference numbers 122a respectively. 124a , The two Zucciniteiles 122 . 124 are interlocking for shipping and sales interlocking in a vacuum packaging 125 sealed, so that the boundary surfaces of the Zuccini pieces created by the cut cover each other outwards.

at all cutting patterns are the respective resulting cut surfaces formed of the cutting material complementary to each other and have a course deviating from a flat course.

While in the above-explained examples, the obtained parts the cutting material respectively composed largely the complete Starting product, it may also be intentional, independent Cut out geometries from a starting product, in which there is a waste that can not be used. So can for example, company logos or the like from fruits or other cutting material to be cut out.

In a modification of the embodiment according to 5 you can also other the apple parts cohesive undercut geometries of the cutting path 112 and thus provide the interface between the apple parts. So shows 8th a cylindrical-crowned undercut 116 and 9 an undercut 116 which is obtained by the fact that the in 5 exactly parallel sections of the cutting path 116 now employed at a small angle.

If you have to secure a falling apart of the parts of the food piece only against small external forces, it is sufficient in the embodiment 4 also out, only two material bridges 110 ' provided at the surface of the apple, ie at the ends of the cutting path 108 lie and can be easily separated from the outside, z. B. using a knife. Possibly. If necessary, one or two internal material bridges can be added 110 use.
