While a book block (P) is nipped between a pair of clamping plates () and passes through processing units (B to D) in succession, perfect book bind processing is carried out. Two or more of the processing units (B to D) have pairs of members () which engage or come into contact with both sides of a back surface of the book block A thickness of the book block is measured by a measuring unit () before the book binding processing is started. When a thickness of next book block is measured by a measuring unit during the book bind processing of a previous book block, a control section () stores a measured value of the thickness of the next book block in a memory (). When the previous book block reaches a predetermined position on a conveying path, a gap between the pair of members of the processing unit located upstream of a position of the previous book block is adjusted based on the measured value stored in the memory. Thereafter, a gap between the pair of members of the processing unit located downstream of the predetermined position is adjusted based on the measured value stored in the memory when the previous book block passes through the processing unit. After the book bind processing of the previous book block is completed, a gap between the pair of clamping plates is adjusted based on the measured value stored in the memory.

Book binding apparatus for perfect book binding

A guillotine cutter () of the invention is provided with a pressing block driving mechanism () positioning a pressing block () at a standby position which is spaced upwardly from a sheet bundle (), a first operating position pressing the sheet bundle by a first pressing force, and a second operating position pressing the sheet bundle by a second pressing force which is larger than the first pressing force. The pressing block is carried by a rod () through a compression spring () at the standby position, the pressing block is supported on an upper surface of the sheet bundle at the first operating position, thereby applying the first pressing force to the sheet bundle on the basis of a resultant force of a gravitational force generated by its own weight and an biasing force generated by the compression spring, and the pressing block is pushed down by an expansion portion () of the rod while the pressing block is kept being supported on the upper surface of the sheet bundle at the second operating position, thereby applying the second pressing force on the basis of a resultant force of the first pressing force and the push-down force generated by the rod.

Guillotine cutter

A lower guillotine cutter blade () is mounted to a frame (). A guillotine cutter-blade holder () holds an upper guillotine cutter blade () and vertically reciprocates with respect to the lower guillotine cutter blade (). Rods () are vertically slidably mounted to the guillotine cutter-blade holder (). A pressing plate () is secured to the lower ends of the rods (). Springs () are fitted around the rods () between the guillotine cutter-blade holder () and the pressing plate () for downwardly elastically biasing the rods () so that the heads () of the rods are kept abutted against the guillotine cutter-blade holder (). In a cutting operation, after the pressing plate () is brought into abutment with a batch of paper (), the guillotine cutter-blade holder () is further downwardly moved, thereby causing the lower and upper guillotine cutter blades (and) to cut the batch of paper () and also causing the heads () to upwardly protrude from the guillotine cutter-blade holder (). At this time, a sensor () mounted to the guillotine cutter-blade holder () detects the distance to the heads (). A thickness measuring element () determines the thickness of the batch of paper () on the basis of the detection signal.

A book binding system for a saddle-stitched bound booklet comprises a sheet feeding section () feeding sheets or sets of sheets (P) one by one, a sheet folding section () sequentially receiving a sheet or a set of sheets (P) from the sheet feeding section () and folding the sheet or the set of sheets (P) along the center line thereof, a sheet stacking section () stacking the sheet or the set of sheets (P) folded by the sheet folding section () in such a manner that the folded sheets or the folded sets of sheets are aligned with each other with respect to the fold lines thereof, a sheet stitching section () receiving a stack of the sheets or the sets of sheets (P') from the sheet stacking section () each time the predetermined number of the sheets or the sets of sheets (P) are stacked in the sheet stacking section, and stitching the stack of the sheets or the sets of sheets (P&#x2032;) at the fold line thereof, and a control section () controlling operation of the sheet feeding section (), the sheet folding section () and the sheet stitching section ().

Book binding method and system for saddle stitched bound booklet

A sheet feeding apparatus comprises a sheet conveying mechanism for conveying sheets along a first conveying path ( ) and stacking up them in a sheet stack-feed station (S), a tray ( ) for storing a stack of cover sheets (P), a second conveying path ( ) communicating with the first conveying path ( ), a blow outlet ( ) for blowing a jet of air towards the tray ( ) to lift up each cover sheet (P), a sucker ( ) for sucking the cover sheet (P), a sheet feeding mechanism for conveying the cover sheet (P) received from the sucker ( ) along the second conveying path ( ) and feeding it to the first conveying path ( ), and a pneumatic pump ( ) for providing a blow of air and a suction of air. The sheet feeding mechanism is changed to its standby mode when the cover sheet is transferred from the sucker ( ) to the sheet feeding mechanism. Upon the sheets having been stacked in the sheet stack-feed station (S), the sheet feeding mechanism transfers the cover sheet. During the standby mode, the pneumatic pump ( ) remains inactivated.

Sheet feeding apparatus

Servers (,) respectively define printing informations (,) inclusive of identifying informations ID,, ID,of a paper block (,) and a cover (,) whereas printing machines (,) respectively perform a printing operation on the paper block (,) and the cover (,). Information readers (,) respectively read the printing informations of the paper block (,) and the cover (,) so as to supply the information thus acquired to a book-binding controller (,). Based on either of the informations thus supplied, the book-binding controller (,) supplies a book binding apparatus (,) or (,) with a control signal (CS) of settings for the book binding process. Additionally, the control signal (CS) of the settings for the book binding process is outputted when the ID,and ID,are in correspondence. Based on the printing information of the paper block, respective quantities of movement of the laterally movable members (,) are automatically regulated.

Book binding system

The present invention provides a collator system comprising a sheet collating device (1a) in which a plurality of sheet supply shelves (2a-2h) are provided, a stack of sheets to be collated are supported on each sheet supply shelf (2a-2h), the sheets are fed one by one from each sheet supply shelf to a collating section (6a) for each collating operation and one sheet bundle is thus collated, a sheet loading device (21) for receiving the sheet bundle collated from the sheet collating device (1a), a controller (14) for controlling operations of the sheet collating device (1a) and the sheet loading device (21), a sheet feeding error detecting section provided on each sheet supply shelf of the sheet collating device (1a), and a sheet feeding error display unit (17) connected to the controller. When the sheet feeding errors are detected by the sheet feeding error detecting section, the controller (14) outputs a stop signal to the sheet collating device (1a) and continues the collating operation which is being performed during the sheet feeding error detection but stops the collating operation to be started after the sheet feeding error detection, and displays, by switching, the sheet supply shelf where the sheet feeding errors occur and the contents of the sheet feeding errors on the same display screen of the sheet feeding error display unit (17) for each collating operation performed after the stop signal is output and before the collating operation of the sheet collating device (1a to 1n) is completely ended.
