Abstract
A book case processing portion of a book production line forms a combination with a device for the removal of at least one book case from a stream of book cases conveyed in a main conveying direction along the book case processing portion of the book production line. The device includes a deposit tray that is extendible into the stream to remove the at least one book case from the stream of book cases.
Claims12
A method for production of books, wherein the books include at least one book block and a book case that protects the book block, comprising:
- supplying a stack of book cases, arranged in a sequence, in a stream along a book production line in a main transporting direction;
- supplying a plurality of book blocks successively along the book production line;
- identifying a marking on each of the book blocks and book cases;
- transmitting an identified marking on at least one book case to a machine control of the book production line;
- correlating, as a result of the marking on the at least one book case, a dataset stored in the machine control for the sequence of book cases in the supplied stack, with the supplied stack, wherein the correlating of the dataset is done by one of the machine control or an operator;
- determining, based on the identified markings of the supplied book blocks, a sequence in the machine control for book blocks positioned on the book production line;
- comparing the dataset for the sequence of the book cases to the sequence of the book blocks;
- and
- if, based on the comparison, at least one book block is missing, relative to the sequence for the book cases, removing at least one book case from the stream of book cases that corresponds to the at least one missing book block, using the machine control.

A combination comprising:
- a book case processing portion of a book production line including a conveyor positioned to receive and convey a stream of book cases in a main conveying direction along the book case processing portion of the book production line;
- and
- a device for removal of at least one book case from the stream of book cases, wherein the device comprises:
- a deposit tray that is positioned to be extendible into the stream to remove the at least one book case from the stream of book cases prior to being received by the conveyor;
- wherein the deposit tray is essentially rectangular-shaped;
- wherein the deposit tray includes an exposed end in an upstream direction of the main conveying direction and an attachment end in a downstream direction of the main conveying direction;
- and
- wherein the attachment end of the deposit tray is positioned along the book case processing portion of the book production line so that the deposit tray is moveable between an upper idle position in which the exposed end of the deposit tray is lifted and does not come in contact with the conveyed stream of book cases, and a lowered catching position in which the exposed end of the deposit tray is lowered to make contact with the conveyed stream of book cases.
