ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates generally to conveying devices for book binding machines. More particularly, the present invention relates to conveying device for book binding machines having continuous plate or cleated chains or similar conveying means. Typically such conveying devices have oppositely disposed longitudinal guides on the conveying track for supporting the plate or cleated chains in the region where inner books or books are clamped therebetween.
In German Patent DE-OS 24 28 620 a plate conveying device for book binding machines is disclosed which comprises a continuous roller chain pair driven by chain wheels. Plates are supported in an articulated manner on the chain studs by means of plate holders. Longitudinal guides which are disposed opposite one another are used to support the plate chains in the clamping zone. The distance between the active plate chain runs, including the longitudinal guides, is adjustable in accordance with the inner book thickness so that the inner books may be firmly clamped and conveyed in a linear direction.
SUMMARY OF THE INVENTION
Briefly stated, the invention in a preferred form is a conveying device which facilitates the release of inner books or books from the conveying device for successive capture by processing stations of a book assembly line. For example the conveying device may release such a book for further processing operations after which the book is returned to the conveying device. Alternatively, an inner book may be released from the conveying device for inspection purposes.
The conveying device includes clamping means having oppositely disposed clamping surfaces for clamping the book or inner book therebetween. The clamping surfaces define a longitudinally extending clamping region having at least one defined subsection. The device also includes guide means slidably engaged with the clamping means for guiding the clamping means. The guide means includes oppositely disposed, longitudinal conveying guides. A control device opens and closes the subsection, where the distance between the clamping surfaces is increased and decreased, respectively, to release or capture the inner book or book, respectively.
The guide means further includes oppositely disposed longitudinal subsection guides which are separate from the conveying guides. The subsection guides are operable by the control device to move the clamping surfaces between a clamping position and an opening position. Oppositely disposed longitudinal transitional guides may be positioned intermediate the subsection guides and the conveying guides. The transitional guides are coupled to the conveying guides and subsection guides by connectors which are received in oval openings or longitudinally extending slots in the conveying guides and subsection guides.
Each of the oppositely disposed clamping surfaces may comprise a roller chain and a continuous plate or cleated chain. The roller chain has a plurality of elongated chain studs which are received in grooves in the conveying guides, subsection guides, and transitional guides.
It is an object of the invention to provide a new and improved conveying device for book binding machines.
It is also an object of the invention to provide a conveying device for book binding machines that releases and recaptures a book or an inner book at multiple processing stations of the book binding machine.
Other objects and advantages of the invention will become apparent from the drawings and specification.
