Embodiment Construction

[0038]FIG. 1 shows a device 1 for controlling the adhesive layer thickness d by means of triangulation and a book block 100 provided with an adhesive layer. The book block 100 is moved in the conveying direction T past the measuring region of the device for controlling the thickness d of the adhesive layer. The device 1 for controlling the adhesive layer thickness d comprises an illumination unit 11 , a camera with an objective lens 10 , an evaluation device 13 and a display device 12 . An illumination unit 11 , for example a laser, projects a light spot onto the adhesive layer of the book block 100 , which is observed with a CCD or CMOS camera 10 . If the distance between the sensor and the surface of the adhesive layer is now changed, the angle at which the camera 10 captures the light spot also changes. Here, the connection of camera 10 -light source 11 and the two rays from and to the objective form a triangle, which is why it is called triangulation. In this case, the d...

Abstract

An adhesive layer for bonding each printed sheet on a book block has dominant influence on the quality of perfect binding. The invention relates to a device for controlling the adhesive layer on a product, especially a book block, an envelope and a cover; wherein the device comprises a device for reading in an 3D optical cross-section profile of the adhesive layer by an laser triangulation method and comprising a high-speed camera and a laser projector, and an analyzing-processing device for analyzing and processing the 3D optical cross-section profile by an analyzing-processing program. If the profile is not accordant with the index value, the product is marked or thrown away.

Description

technical field [0001] The invention relates to a device for controlling and regulating the adhesive layer to be applied during the manufacture of printed products according to the preamble of claim 1 and to a device for controlling and regulating the adhesive layer to be applied according to claims 9 and 11. method of adhesive layer. Background technique [0002] In the manufacture of printed products, especially books, basically two book structures are distinguished, namely hardcover (hard cover) and multi-layer paperback (paper). [0003] For hardcover books, the folds and / or individual pages are first combined into a so-called book block. The back of the book is covered with one or more layers of adhesive followed by a fold ( ), which extends into the portion of the front and back pages near the back of the book. The multi-part cover is then placed around the book block and is firmly and completely connected to the book block on the front and back pages. The back of...
