Container handling system
A container handling system includes first and second rotary machines each comprising transport elements for transporting containers along first and second conveying paths, where the second conveying path is downstream of the first conveying path, a memory device, and a control device configured to determine during transport of a container that first and second transport elements transport containers in the first and second rotary machines and to store identifiers assigned to the first and second transport elements in the memory device, to ascertain whether an error is occurring during transport of the container through the container handling system, and to retrieve a stored identifier from the memory device if it is ascertained that the error has occurred.
1 . A container handling system, comprising:
a first rotary machine comprising a plurality of transport elements for transporting one container each along a first conveying path;

a memory device; and
a control device;
where said control device during transport of a container through said container handling system is configured
to determine that a first transport element transports said container in said first rotary machine and to store an identifier assigned to said first transport element in said memory device;
to determine that a second transport element transports said container in said second rotary machine and to store an identifier assigned to said second transport element in said memory device;
to ascertain whether an error is occurring during transport of said container through said container handling system; and
to retrieve at least one stored identifier from said memory device if it is ascertained that the error has occurred during transport of said container;
wherein said memory device comprises a shift register, and wherein said control device is configured to store the identifier of said first transport element and of said second transport element in said shift register,
wherein said shift register has a predetermined number of memory elements,
wherein the predetermined number of memory elements corresponds to a number of transport positions that said container passes through during transport through said container handling system, wherein said container is moved on from one transport position to the next by a transport step,
wherein said control device is configured to determine a first transport position at which said container is located at a first point in time and to store the identifier of said first transport element and/or of said second transport element in said memory element that corresponds to said first transport position, and
wherein said control device is configured to determine that, at a second point in time, a specific number of transport steps has taken place since the first point in time, and to store in said memory element the identifier of said first transport element and/or of said second transport element which corresponds to a transport position at which said container is located at the second point in time based on the specific number of transport steps.
2 . The container handling system according to claim 1 , wherein said control device is configured to determine the identifier of said first transport element and of said second transport element based on a position of a drive of said first rotary machine or of said second rotary machine.
3 . The container handling system according to claim 1 , wherein said control device is configured:
to not store the identifier of said second transport element in said memory device as long as said container is disposed on said first conveying path, or
to store a placeholder as the identifier of said second transport element in said memory device as long as said container is disposed on said first conveying path.
4 . The container handling system according to claim 3 , wherein the placeholder stored as the identifier of said second transport element in said memory device is zero.
5 . The container handling system according to claim 1 , wherein said control device is configured to increment at least one counter for a number of errors for each rotary machine if it is ascertained that an error has occurred during transport of said container along said conveying path of this rotary machine or of a downstream rotary machine.
6 . The container handling system according to claim 5 , wherein the at least one counter comprises a counter for a type of error and/or a counter for said first rotary machine and/or a counter for a rotary machine downstream of said first rotary machine, and/or a counter for the identifier of said first transport element, and/or a counter for the identifier of said second transport element.
7 . The container handling system according to claim 1 , wherein said control device is configured for each rotary machine to link the identifier of at least one transport element of said respective rotary machine to a position of a drive of said respective rotary machine.
8 . The container handling system according to claim 1 , wherein determining the first position at which said container is located at said first point in time based on a position of a drive of said first rotary machine or of said second rotary machine.
9 . A method for controlling a container handling system, comprising:
determining that a first transport element of a first rotary machine of said container handling system transports a container in said first rotary machine along a first conveying path and storing in a memory device of said container handling system an identifier assigned to said first transport element;
determining that a second transport element of a second rotary machine of said container handling system transports said container in said second rotary machine along a second conveying path and storing in the memory device of said container handling system an identifier assigned to said second transport element;
ascertaining whether an error is occurring during transport of said container through said container handling system;
retrieving at least one stored identifier from said memory device if it is ascertained that the error has occurred during transport of said container;
storing the identifier of said first transport element and of said second transport element in a shift register of said memory device, where said shift register has a predetermined number of memory elements, where the predetermined number of memory elements corresponds to a number of transport positions that said container passes through during transport through said container handling system, where said container is moved on from one transport position to the next by a transport step;
determining a first transport position at which said container is located at a first point in time and storing said identifier of said first transport element and/or of said second transport element in said memory element that corresponds to said first transport position; and
determining that, at a second point in time, a specific number of transport steps has taken place since the first point in time, and storing in said memory element the identifier of said first transport element and/or of said second transport element which corresponds to a transport position at which said container is located at the second point in time based on the specific number of transport steps.
10 . The method according to claim 9 , further comprising:
determining said identifier of said first transport element and of said second transport element based on a position of a drive of said first rotary machine or of said second rotary machine.
11 . The method according to claim 9 , further comprising:
not storing the identifier of said second transport element in said memory device as long as said container is disposed on said first conveying path, or
storing a placeholder as the identifier of said second transport element in said memory device as long as said container is disposed in said first conveying path.
12 . The method according to claim 9 , further comprising:
incrementing at least one counter for a number of errors if it is ascertained that an error has occurred during transport of said container along said conveying path of this rotary machine or of a downstream rotary machine.
13 . The method according to claim 12 , where the at least one counter comprises a counter for a type of error and/or a counter for said first rotary machine and/or a counter for a rotary machine downstream of said first rotary machine, and/or a counter for the identifier of said first transport element, and/or a counter for the identifier of said second transport element.
14 . The method according to one of the claim 9 , further comprising:
linking, for each rotary machine, the identifier of at least one transport element of said respective rotary machine to a position of a drive of said respective rotary machine.
