Apparatus and method for cutting a plurality of food products
An apparatus for simultaneously slicing a plurality of food products into portions including a plurality of product slices respectively is provided. The apparatus includes a cutting blade which rotates about a blade axis in a cutting plane and/or revolves about a center axis in a planetary motion and includes a multi-track product feed. The feed of the product in one track is respectively interrupted if the residual product remainder in the track is no longer sufficient for forming a complete portion and if the residual product remainder in at least one of the other tracks is still sufficient for forming at least one complete portion. The product remainders are sliced into incomplete part portions once the product remainders of all tracks have reached a dimension which is no longer sufficient for forming a complete portion. The incomplete part portions are completed by product slices of subsequent products.
1. A method for simultaneously slicing a plurality of food products into portions each including a plurality of product slices, the plurality of food products being sliced by a common slicing apparatus having at least one rotary cutting blade disposed in a cutting plane to which the plurality of food products are fed on a plurality of tracks, the method comprising the steps of:
interrupting a feed of a food product in a track of one of the plurality of tracks if a residual food product remainder in the track is no longer sufficient for forming at least one complete portion and if the residual food product remainder in at least one other track is still sufficient for forming at least one complete portion;
slicing the residual food product remainders into incomplete part portions once the residual food product remainders of all of the plurality of tracks have reached a dimension which is no longer sufficient for forming the at least one complete portion; and
completing the incomplete part portions by a product slice of following food products.
2. The method in accordance with claim 1 , including at least one of the steps of rotating the rotary cutting blade about a blade axis, and revolving the rotary cutting blade about a center axis in a planetary motion.
3. The method in accordance with claim 1 , comprising the step of moving the incomplete part portions only together in and against a conveying direction.
4. The method in accordance with claim 3 , and comprising the step of using a conveyor unit not divided transversely to the conveying direction.
5. The method in accordance with claim 3 , comprising the step of moving the food product into a blank cut position retracted with respect to the cutting plane on interruption of the feed.
6. The method in accordance with claim 1 , the method comprising the step of coordinating slicing of the residual food product remainders in the plurality of tracks such that slicing ends simultaneously in all of the plurality of tracks.
7. The method in accordance with claim 1 , comprising the step of coordinating a time sequence of slicing of the residual food product remainders in individual ones of the plurality of tracks with reference to a size of the respective residual food product remainders.
8. The method in accordance with claim 7 , comprising the step of starting coordination with a largest residual food product remainder on slicing of the residual food product remainders.
9. The method in accordance with claim 1 , the method including the step of starting completing of the incomplete part portions in all of the plurality of tracks simultaneously.
10. The method in accordance with claim 1 , the method comprising the step of aligning the at least one complete portions in the plurality of tracks relative to one another with respect to a conveying direction after the completing step.
11. The method in accordance with claim 10 , wherein aligning is carried out such that front edges of the at least one complete portions in all of the plurality of tracks are generally at the same level with respect to the conveying direction.
12. The method in accordance with claim 1 , comprising the step of slicing of the residual food product remainders simultaneously in all of the plurality of tracks.
13. The method in accordance with claim 1 , further comprising the step of coordinating the completing of the incomplete part portions in the plurality of tracks such that a last product slice required for completion is added simultaneously to the incomplete part portions of all of the plurality of tracks.
14. The method in accordance with claim 1 , comprising the step of making a start, on the completing of a part portions, with one of the part portion having a highest number of product slices required for completion.
15. The method in accordance with claim 1 , in which the step of completing of the incomplete part portions takes place after a common intermediate positioning in a waiting region and a common return into a portioning region.
16. The method in accordance with claim 15 , including one of the steps of first returning rear edges of all of the incomplete part portions into a completion position simultaneously and returning only a rear edge of a first part portion into a completing position, with the rear edges of other part portions being guided back beyond the completion position.
