摘要:
Die Erfindung befaßt sich mit der Vibrationsbeseitigung bei einer Zuführkette oder einem Förderer 12 von Maschinen zum Sammeln von bedruckten Bögen. Die Hin- und Herbewegung in einigen Bestandteilen des Systems schafft ständig wiederkehrende Kräfte, die bei oder in der Nähe der Eigenschwingungszahl der Zuführkette 12 liegen können. Dies verursacht unerwünschte Schwingungen in der Kette. Die Erfindung dämpft diese Schwingungen durch ein ständiges Einschränken im Bereich des unteren Laufes der Kette 12 sowie durch die Anordnung eines positiven Antriebs 92 an dem Endteil der Kette 12, um etwas von dem Spiel beim Rücklauf aufzunehmen. Die Vibration wird auch reduziert an ihrer Quelle durch das Anordnen eines Schwungrades 40 auf der Antriebsachse 36 in der Nähe des Punktes, wo die Hin- und Herbewegung entsteht.
摘要:
A saddle binding system is provided with a reject device (10) which removes misformed books from the gathering chain (24) and transports them to a tray (82) for recycling. The reject device (10) includes an arm (50) pivotally mounted adjacent the chain on a frame. The arm (50) is normally located in a rest position out of engagement with passing books. An actuator is connected to the arm (50) and is operable to pivot the arm to a raised, book-engaging position. In the raised position the arm (50) elevates the leading edge portion of a misformed book (112) off of the gathering chain (24), thereby rotating the book. This rotation advances the trailing edge of the book out of engagement with the pusher pin (26) of the gathering chain. A tape-and-roller take-away mechanism (14) is positioned above the chain to engage an elevated edge portion of a book. The take-away mechanism is angled such that it moves the book longitudinally and vertically of the gathering chain (24), as well as laterally. The book is discharged to a reject tray (82).
摘要:
Cyclically operable signature machine having a one-way drive means to incrementally advance a signature infeeding conveyor synchronously to the action of an oscillating suction finger (12) for withdrawing a signature (S) from a stack in a hopper (10); in a cycle where a signature (S) is not to be fed, the suction finger (12) is latched and simultaneously the one-way drive means is disabled to prevent the stack from being compacted.
摘要:
Signature gathering machine in which signatures (5) are extracted by an extracting cylinder (32) successively from a hopper (20), released at a register gauge (22), opened by grippers (75) on opposed opening cylinders (24, 26) and then those grippers are opened to drop the signature (5) onto a saddle conveyor (28); wipers (60) rotate with the extracting cylinder (32) and are actuated in timed relation to arrival of the signature (5) at the register gauge (22) so as to force the free edges of the signature (5) into the space between the opening cylinders (24, 26) .
