Abstract

Claims (44)

1 . A method for grouping and/or separating products ( 2 ) transported in rows, wherein the method comprises:

conveying, with the aid of a first conveyor belt ( 1 ), the products ( 2 ) to be grouped or separated onto a second conveyor belt ( 3 ) connected in series with the first conveyor belt ( 1 ) until a downstream product of the products ( 2 ) to be grouped or separated runs up against a dividing web ( 4 ) of a dividing device ( 5 ) associated with the second conveyor belt ( 3 ); and

interrupting, after or as the downstream product runs up against the dividing web ( 4 ), a conveyance of products ( 2 ) into the upstream region of the second conveyor belt ( 3 ) effected by means of the first conveyor belt ( 1 ),

wherein the second conveyor belt ( 3 ) is driven continuously in a transport direction ( 7 ) specified by the second conveyor belt ( 3 ), and wherein the dividing web ( 4 ) travels along with the second conveyor belt ( 3 ) in its transport direction ( 7 ) over a defined distance and is then removed from the product flow of the second conveyor belt ( 3 ),

configuring the control device ( 11 ) to stop a drive device associated with the first conveyor belt ( 1 ) to interrupt the conveyance of products ( 2 ) into the upstream region of the second conveyor belt ( 3 ) effected by means of the first conveyor belt ( 1 ); and/or

controlling a retention device ( 12 ) with a pressure element, in the form of a pressure plate, provided at the downstream end region of the first conveyor belt to interrupt the conveyance of products ( 2 ) into the upstream region of the second conveyor belt ( 3 ) effected by means of the first conveyor belt ( 1 ).

2 . The method according to claim 1 ,

wherein, after the dividing web ( 4 ) is removed from the product flow of the second conveyor belt ( 3 ), the dividing web is moved back again counter to the transport direction ( 7 ) of the second conveyor belt ( 3 ) into an upstream region of the second conveyor belt ( 3 ), in which the products ( 2 ) conveyed by the first conveyor belt ( 1 ) run up against the dividing web ( 4 ) that has been moved back.

3 . The method according to claim 2 ,

wherein, after the dividing web ( 4 ) is moved back into the upstream region of the second conveyor belt ( 3 ), a conveyance of products ( 2 ) into the upstream region of the second conveyor belt ( 3 ) effected by means of the first conveyor belt ( 1 ) is resumed, so that, with the aid of the first conveyor belt ( 1 ), the products ( 2 ) to be grouped or separated are again conveyed onto the second conveyor belt ( 3 ), until a downstream product of the products ( 2 ) to be grouped or separated runs up against the dividing web ( 4 ) which has been moved back into the upstream region of the second conveyor belt ( 3 ).

4 . The method according to claim 1 ,

wherein the dividing device ( 5 ) associated with the second conveyor belt ( 3 ) is configured in order to, after the dividing web has been removed from the product flow of the second conveyor belt ( 3 ), move the dividing web ( 4 ) back into an upstream region of the second conveyor belt ( 3 ), in which the products ( 2 ) conveyed by the first conveyor belt ( 1 ) can run up in accordance with a time and/or event sequence, which is defined or definable in advance such that, with respect to the second conveyor belt ( 3 ), a repeat length ( 8 ) and/or a gap length ( 10 ) between two adjacent separated products or product groups ( 16 ) on the second conveyor belt ( 3 ) is variable and continuously adjustable.

5 . The method according to claim 1 ,

wherein, for transporting the dividing web ( 4 ), the dividing device ( 5 ) associated with the second conveyor belt ( 3 ) comprises at least one circulating endless belt ( 13 ), which is configured in order to guide and/or transport the dividing web ( 4 ) in a closed curve, wherein, when the dividing web ( 4 ) is moved back to the upstream region of the second conveyor belt ( 3 ), the dividing web ( 4 ) is guided and/or transported above, below, or to the side of a conveying plane of the second conveyor belt ( 3 ).

6 . The method according to claim 1 ,

wherein a speed at which the dividing web ( 4 ) travels along with the second conveyor belt ( 3 ) in its transport direction ( 7 ) over the defined distance is adjustable and is coordinated with the transport speed of the second conveyor belt ( 3 ) such that the speed of the dividing web ( 4 ) as it travels along with the second conveyor belt ( 3 ) in its transport direction ( 7 ) corresponds at least substantially to the transport speed of the second transport belt ( 3 ).

7 . The method according to claim 1 ,

wherein a speed at which the dividing web ( 4 ) travels along with the second conveyor belt ( 3 ) in its transport direction ( 7 ) over the defined distance is adjustable and is coordinated with the transport speed of the second transport belt ( 3 ) such that the speed of the dividing web ( 4 ) as and/or immediately before it is removed from the product flow of the second conveyor belt ( 3 ) is greater than the transport speed of the second conveyor belt ( 3 ).

8 . The method according to claim 1 ,

wherein the dividing device ( 5 ) associated with the second conveyor belt ( 3 ) comprises at least two dividing webs ( 4 ) which are guided and/or transported by the circulating endless belt ( 13 ).

9 . An apparatus ( 100 ) for grouping and/or separating products ( 2 ) transported in rows, wherein the apparatus ( 100 ) comprises the following:

a horizontal conveying device comprising an upstream first conveyor belt ( 1 ) and a downstream second conveyor belt ( 3 ) connected in series with the first conveyor belt ( 1 );

a dividing device ( 5 ) associated with the second conveyor belt ( 3 ) comprising at least one dividing web ( 4 ); and

a control device ( 11 ), which is configured to operate the first conveyor belt ( 1 ) in particular in a start-stop mode,

wherein the dividing device ( 5 ) is configured to guide the at least one dividing web ( 4 ) in a closed curve such that the at least one dividing web ( 4 ) travels along with the second conveyor belt ( 3 ) in its transport direction ( 7 ) over a defined distance and is then removed from the product flow of the second conveyor belt ( 3 ) and moved back again counter to the transport direction ( 7 ) of the second conveyor belt ( 3 ) into an upstream region of the second conveyor belt ( 3 ),

wherein the first conveyor belt ( 1 ) is configured to convey the products ( 2 ) to be grouped or separated into the upstream region of the second conveyor belt ( 3 ), and
