Book block transport system

Abstract

A book block transport system with a plurality of book block clamps (1) each having a supporting frame (2) that is supported in guides and carries an inner clamping jaw (3) and a pivot frame (4) that is suspended on a shaft (6) of the supporting frame (2) extending parallel thereto for accommodating an outer clamping jaw (5). The pivoting movement for opening and closing the outer clamping jaw (5) is controlled by a cam track, with a spring element (13) that generates the clamping force between the inner and outer clamping jaws (3 and 5). A book stop catch (30, 40) is carried on the book block clamp (1) for aligning the book block supplied by an infeed device. In order to reliably and flawlessly transfer and align the book blocks supplied by an infeed device, the book stop catch (30, 40) is arranged on the book block clamp (1) such that it can be moved relative to the inner clamping jaw (3). Only a small transport gap is required between two successively supplied book blocks such that the book block clamps (1) are able to transport a larger format height relative to the clamp pitch.

Description

BRIEF DESCRIPTION OF THE DRAWING

Embodiments of the invention are described in greater detail below with reference to the figures, wherein:

FIG. 2 is an identical representation of a book block clamp with a book stop catch that is arranged on the inner clamping jaw in a pivoting fashion.

Claims

1. A book block transport system with a plurality of book block clamps that can be continuously moved along a closed loop and are connected to one another in a motive fashion, said clamps comprising: a supporting frame that is supported in guides associated with said loop and carries an inner clamping jaw;a pivot frame that is suspended on a shaft of the supporting frame extending parallel thereto and accommodating a pivotable, outer clamping jaw, wherein the pivoting movement for opening and closing the outer clamping jaw is controlled by a cam track associated with said loop;a spring element that generates a clamping force between the inner and outer clamping jaws; anda book stop catch on the book block clamp for aligning the book block supplied by an infeed device;wherein the book stop catch is moveable relative to the inner clamping jaw.

2. The book block transport system according to claim 1, wherein the book stop catch is moveable transverse to the feed direction of the book blocks during or before the closing of the outer clamping jaw.

3. The book block transport system according to claim 1, wherein the book stop catch is moveable away from the book block to be fed along a straight transport section of the book block clamps during the opening of the outer clamping jaw.

4. The book block transport system according to claim 1, wherein at least one jaw has a lower longitudinal edge and the book stop catch is moveable in a plane that extends perpendicular to the lower longitudinal edge.

5. The book block transport system according to claim 4, wherein the book stop catch is moveable perpendicular to the inner clamping jaw.

6. The book block transport system according to claim 4, wherein the movement travel or the length (L) of the book stop catch is adjustable in dependence on the block thickness of the book block to be fed.

7. The book block transport system according to claim 1, wherein the book stop catch features an overload safety.

8. The book block transport system according to claim 1, wherein the book stop catch is arranged on the outer clamping jaw.

9. The book block transport system according to claim 8, wherein the book stop catch is fixed on an outer clamping jaw that is accommodated in the pivot frame.

10. The book block transport system according to claim 1, wherein the book stop catch is arranged on the inner clamping jaw and is moveable with the aid of a controller.

11. The book block transport system according to claim 10, wherein the controller comprise a cam track that is arranged rigidly relative to the frame at one or more locations of the loop.

12. The book block transport system according to claim 1, wherein the book stop catch features aligning elements for a supplied cover, wherein the book stop catch with the aligning elements is positioned above the block spine until the cover supply is reached.

13. The book block transport system according to claim 2, wherein the book stop catch is moveable away from the book block to be fed along a straight transport section of the book block clamps during the opening of the outer clamping jaw.

14. The book block transport system according to claim 2, wherein at least one jaw has a lower longitudinal edge and the book stop catch is moveable in a plane that extends perpendicular to the lower longitudinal edge.

15. The book block transport system according to claim 3, wherein at least one jaw has a lower longitudinal edge and the book stop catch is moveable in a plane that extends perpendicular to the lower longitudinal edge.

16. The book block transport system according to claim 5, wherein the movement travel or the length (L) of the book stop catch is adjustable in dependence on the block thickness of the book block to be fed.

17. The book block transport system according to claim 2, wherein the book stop catch is arranged on the outer clamping jaw.

18. The book block transport system according to claim 17, wherein the book stop catch is fixed on an outer clamping jaw that is accommodated in the pivot frame.

19. The book block transport system according to claim 2, wherein the book stop catch is arranged on the inner clamping jaw and is moveable with the aid of a controller.
