Abstract

In order to prevent a slice from being separated from each log during the last cut in the case of multiple portions produced in parallel, that is to say there is no unproductive cut in the last cut, as is required, for example, in EP 2942165 B1, the basic idea is to already provide an unproductive cut for at least one log during the first cut for the simultaneously produced portions, wherein a distinction must be made in the following procedure whether or not separately controllable portioning belts are present per lane and whether the portion lengths should be the same or not despite different numbers of slices.

First claim

What is claimed is:

1. A method for parallel, substantially simultaneous production of shingled portions with different numbers of slices by use of a multi-lane slicing machine for product logs with a rotating blade and portioning belts that can be controlled individually for each lane downstream of the blade, the method comprising:
during slicing of a portion, separating by the blade a slice from each of the logs supplied in parallel during at least one revolution of the blade; and
controlling the portioning belts such that a length of each of the portions produced in parallel next to one another is approximately the same independent of number of slices in each of the portions;
wherein no slice is separated from at least one log during a first cut for a portion.

2. The method according to claim 1 , wherein a slice distance of adjacent slices within the portions is selected such that the portion length is the same in all portions independently of the number of slices.

3. The method according to claim 1 , wherein one slice is separated from each log during each cut between a first cut and a last cut.

4. The method according to claim 1 , wherein the at least one log from which no slice is separated during the first cut for a portion comprises multiple logs that are selected of a same type.

5. The method according to claim 4 , wherein the multiple logs have a same consistency.

6. The method according to claim 1 , wherein no slice is separated from multiple logs during a last cut for a portion, and the multiple logs are selected of a same type.

7. The method according to claim 6 , wherein the multiple logs have a same consistency.

8. The method according to claim 1 , a slice distance is selected to be equal within all parallel portions.

9. The method according to claim 1 , wherein no slice is separated from at least one log in a last cut for a portion.

10. The method according to claim 1 , wherein multiple portions of the portions produced next to one another are subsequently introduced together into a packaging, spaced apart or partially overlapping in a transverse direction, and wherein before or during combining, front ends and/or rear ends of the multiple portions are brought to a same longitudinal position in the packaging.

11. The method according to claim 10 , wherein after a penultimate cut for the multiple portions produced next to one another, only the portioning belts of those lanes on which a last slice still has to be deposited for this portion are moved forwards.

12. The method according to claim 1 , wherein multiple portions of the portions produced simultaneously next to one another are then introduced together into a packaging, spaced apart or partially overlapping in a transverse direction, and wherein before or during combining, the multiple portions are left in their relative position relative to one another in a longitudinal direction.

13. The method according to claim 1 , wherein multiple portions of the portions produced next to one another are subsequently introduced together into a packaging, at a distance or partially overlapping in a transverse direction, and wherein before or during combining, the multiple portions are brought to a smaller initial distance and/or end distance from one another in a longitudinal direction than was present on the portioning belts.

14. A multi-lane slicing machine for slicing product logs into slices and producing shingled or stacked portions from slices, the slicing machine comprising:
a slicing unit having a blade;
a feeding unit for feeding multiple logs to the slicing unit;
a discharge unit having at least one portioning belt; and
a controller configured to control the slicing unit and the feeding unit such that during slicing of a portion, the blade separates a slice from each of the logs supplied in parallel during at least one revolution of the blade, and to control the at least one portioning belt such that a length of each of the portions produced in parallel next to one another is approximately the same independent of number of slices in each of the portions, and wherein the controller is configured to control the slicing machine such that no slice is separated from at least one log during a first cut for a portion.

15. The slicing machine according to claim 14 , wherein the at least one portioning belt comprises a portioning belt in each lane and the portioning belts are controllable independently of one another.
