ABSTRACT:
The invention relates to a method and to a device for creating a product flow according to a predefined sequence (S). The products (A, B, C) are fed from different feed flows of a grouping path (G) and there, according to the sequence (S), are deposited onto a conveyor (10, 10) with a closed revolving path (U). According to the invention a repair function is realised in which the products (A, B, C) are then only transferred from the conveyor to a further-processing station if the sequence (S) is correct and all products (A, B, C) are present with the desired quality. Otherwise, the products (A, B, C) are led by the continuously operated conveyors (A, B, C) back to the grouping path (G). Here, the error is corrected by way of the deposition of the missing product (A, B, C), whilst the deposition of new products (A, B, C) is interrupted. For error correction, one may previously provide a discharge of a defect or wrong product (A, B, C). After the error correction, the creation of the product flow is continued by way of the sequentially correct deposition of further products (A, B, C). The method permits the error-free and sequentially correct creation of infinitely long and infinitely assembled sequences (S).
