Abstract

An apparatus for slicing food products includes a product supply device that supplies a product to a cutting plane and a support table, onto which the product slices fall. The support table is provided with a controllable motor drive that displaces the support table relative to the falling product slices to form portions of any desired shape from a plurality of product slices. A formatting device includes a display device, on which product slices can be realistically presented. A user can prepare any desired formats from a plurality of product slices using a format function on the display device. An evaluation device converts the positions of the product slices into control commands for the motor drive, on the basis of which the motor drive displaces the support table based on the cutting speed to form portions on the support table that correspond to the format prepared on the display device.

An apparatus in accordance with claim 1, wherein the support table (17) is made as an endless conveyor with one or a plurality of endless conveyor bands (39) and a drive (19, 35) for the displacement movement for the formation of the portions of any desired shape is identical to the drive for the normal conveying operation for the transporting away of complete portions.

5. An apparatus in accordance with claim 1, wherein a spindle drive (21, 37) is provided for a displacement movement of the support table (17) transversely to the conveying direction (x), with the support table (17) preferably being displaceable as a whole.

6. A formatting apparatus for use with a cutting apparatus, in particular a high-performance slicer, for the slicing of food products (11), wherein the cutting apparatus comprises a product supply device (13) which supplies a product (11) to be sliced to a cutting plane (15) in which a cutting knife moves, in particular in a revolving manner, and a support table (17), in particular made as a portioning band, onto which the product slices cut off by means of the cutting knife fall and which is provided with a controllable motor drive (19, 21), which displaces the support table (17) relative to the falling product slices to form portions of any desired shape from a plurality of product slices;

wherein the formatting apparatus comprises;

a formatting device (23), in particular in the form of a touch screen, on which product slices (25) can be realistically presented and which has a formatting function by means of which a user (27) can prepare any desired formats (29) from a plurality of product slices (25) on the display device (23); and

an evaluation device (31), which converts the positions of the product slices (25) forming a prepared format (29) on the display device (23) into control commands for the motor drive (19, 21) on the basis of which the motor drive (19, 21) displaces the support table (17) in dependence on the cutting speed such that portions are formed on the support table (17) in accordance with the format (29) prepared on the display device (23).

7. A formatting apparatus in accordance with claim 6, wherein the product slices (25) shown are displaceable on the display device (23), in particular using a drag and drop function.

8. A formatting apparatus in accordance with claim 6, wherein the display device (23) comprises a touch screen on which the product slices (25) shown are movable by touching with a finger of the user or using a working aid, in particular in pen form.
