Container handling system

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 second rotary machine comprising a plurality of transport elements for transporting one container each along a second conveying path, where said second conveying path is arranged downstream of said 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.
