Abstract

A conveyor device is provided for conveying food products in stacks or interleaved units made of a plurality of slices of cheese or meat products. The conveyor device formats the food products in a specific product format on a plurality of parallel conveyor tracks, and fills a product gap on one of the plurality of parallel conveyor tracks incoming on the input side with a food product so that on the output side all parallel conveyor tracks are supplied with the food products. At least one product sensor is configured to detect a supply of food product on each conveyor track incoming on the input side.

First claim

What is claimed is:

1. A conveyor device for conveying food products in stacks or interleaved units made of a plurality of slices of cheese or meat products, the conveyor device comprising:
a plurality of parallel conveyor tracks having an input side and an output side, wherein the conveyor device formats the food products in a specific product format on the plurality of parallel conveyor tracks, and wherein the conveyor device fills a product gap on one of the plurality of parallel conveyor tracks incoming on the input side with a food product so that on the output side all parallel conveyor tracks are supplied with the food products;
at least one product sensor configured to detect a supply of food product on each conveyor track incoming on the input side;
wherein, when an even number of product gaps exist on one of the conveyor tracks, the conveyor device fills the product gaps with a corresponding number of food products from another one of the conveyor tracks that does not have any product gaps such that at least one of the food products are transferred from the conveyor track that does not have any product gaps to the conveyor track that has the product gaps; and
wherein when there is an odd number of product gaps on one of the conveyor tracks, the conveyor device also fills the product gaps with food products from a product buffer such that at least one of the food products is transferred from the product buffer to the conveyor track that has the product gap.

2. The conveyor device according to claim 1 , further comprising
a distributor conveyor downstream of the conveying tracks;
a buffer conveyor which forms the product buffer for the food products and is fed by the distributor conveyor with the food products;
a main flow conveyor configured to convey a main flow of the food products and is selectively loaded with the food products from the distributor conveyor or from the buffer conveyor, the main flow conveyor being downstream of the distributor conveyor; and
a shuttle conveyor for transferring the food products between the parallel conveying tracks for filling the product gaps, wherein the shuttle conveyor is arranged in the conveying direction behind the main flow conveyor.

3. The conveyor device according to claim 2 , wherein
the distributor conveyor with its output end is vertically adjustable between the buffer conveyor and the main flow conveyor in order to feed either the buffer conveyor or the main flow conveyor with the food products entering on the input side.

4. The conveyor device according to claim 3 , wherein the shuttle conveyor can be moved transversely to the conveying direction.

5. The conveyor device according to claim 2 , wherein the shuttle conveyor can be moved transversely to the conveying direction.

6. The conveyor device according to claim 3 , wherein
the buffer conveyor is arranged above the main flow conveyor and is vertically adjustable with its output end, the buffer conveyor with its output end can be lowered to the main flow conveyor in order to place one of the food products on the main flow conveyor for the subsequent filling of a product gap, and the buffer conveyor with its output end can be lifted by the main flow conveyor in order not to block the continuous main flow of food products.

7. The conveyor device according to claim 2 , wherein in the buffer conveyor the conveying speed of the individual conveying tracks is separately adjustable from another, so that the buffer conveyor can transfer a single food product on only one of the conveying tracks to the main flow conveyor.

8. The conveyor device according to claim 2 , further comprising a transfer conveyor with several parallel conveying tracks, wherein the transfer conveyor is arranged in the conveying direction behind the shuttle conveyor and is fed by the shuttle conveyor with the food products, wherein in the transfer conveyor the conveying speed of the individual conveying tracks is separately adjustable to take over only a single food product in only one of the conveying tracks.
