Abstract

Two book block guide surfaces (2, 2') are arranged in the flat-link chain or belt conveyor tracks (1, 1'). Each book block guide surface (2, 2') is provided with air jets (3, 3'). A book block (10), consisting of individual sheets or layers, is introduced by book block conveyor means between the book block guide surfaces (2, 2'). The air emerging from the air jets (3, 3') compresses the book block (10) so that the individual sheets or layers of the book block (10) do not slide relative to each other. Even at a high conveying speed, the book blocks (10) move completely without sliding, so that the maximum possible output is achieved in book block processing. <IMAGE>

Description

(54) APPARATUS TO GRIP AN UNBOUND BOOK BLOCK (71) We, VEB KOMBINAT POLY GRAPH 'WERNER LAMBENZ' LEIPZIG, formerly VEB Polygraph Leipzig Kombinat fur polygraphische Maschinen und Ausrüs- tungen, of 705 Leipzig, Zweinaundorfer Str.
59, German Democratic Republic, a corporation organised under the laws of the German Democratic Republic, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to an apparatus to grip an unbound book block. Such an apparatus finds use in, for example, an adhesive binding machine.
It is known to provide plate chain or belt conveyor tracks which grip still unbound book blocks between their plate chain or belt runs and convey them away in a horizontal direction by way of processing stations for the adhesive binding and possibly to other working stations (see, DL-GM 16755, DT-PS 120u289, DL-PS 108954). Displacements of the individual leaves or sheet layers relative to one another occur on the introduction of the book blocks between the plate chain or belt runs.
Such displacements result in the outer leaves or layers of the book blocks fed forward unpressed to remain behind relative to the inner leaves or layers, due to the pressure of introduction. This phenomenon grows with increasing conveying speed. Such displacements later act disadvantageously on the quality of the adhesively bound book blocks. The conveying speed must consequently be held so low that the displacements remain within tolerable limits. Thereby, the performance of the entire machine is however appreciably reduced.
According to the present invention there is provided an apparatus to grip an unbound book block comprising a plurality of leaves, the apparatus comprising conveyor means to grip pingly receive and convey the book block along a given direction, and air nozzles arranged in such a manner at an input region of the conveyor means for receiving the book block as in use to direct an air current at the two outer faces of the book block.
The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 shows a first embodiment of a gripping device according to the invention; Fig. 2 shows details of a book block guide surface; and Fig. 3 shows a second embodiment of a gripping device according to the invention.
Referring now to the drawing, Fig. 1 shows two book block guide surfaces 2 and 2' stationed in the book block insertion region of a known plate chain or belt conveyor track 1 and l' illustrated only stylised in Fig. 1. Each of these two book blocks guide surfaces is bent away at its book block inlet side and provided at its surface with air blast jets 3 and 3' provided in the shape of bores. The book block guide surfaces 2 and 2' with the air blast jets 3 and 3' reach as far as possible towards the plate chain or belt conveyor track 1 and 1'.
For this purpose, they are structured to be running pointedly in the conveying direction.
Furthermore, each book block guide surface 2 and 2' is provided at its rear side with a counter wall 4 and 4'. A cover is present above and below so that the book block guide surface 2 and 2' with its counter wall 4 and 4' forms an air blast chamber 5 and 5'. As shown in Fig. 2, the counter wall 4 and 4' is fastened by means of screws 6 to a holder 7 and 7', which is provided with an air blast channel 8 and 8'. An aperture 9 and 9' connects the air blast channel 8 and 8' with the air blast chamber 5 and 5'. The air blast channel 8 and 8' is connected to an in itself known air blast feed (not shown). Fig. 2 shows the elevation of the book block guide surface 2, which is directed towards a book block (not shown).
With the machine switched on, air blast constantly flows out of the air blast jets 3 and 3'. In Fig. 1, this air blast is characterised by small arrows. A book block 10 comprising individual leaves or layers is introduced by known book block conveying means (not shown) between the book block surface 2 and 2'. The air blast issuing out of the air blast jets 3 and 3' compresses the book block 10 so that the individual leaves or layers of the book block 10 cannot displace relative to one another.
Furthermore, a narrow air cushion arised between the outer leaves of the book block 10 and each of the book block surfaces 2 and 2' and appreciably reduces the friction between the two. Advantageously, the book block 10 is thereby guided free of displacement in an un objectionably aligned state during the feed to the plate chain or belt conveyor track 1 and 1'.
This state is however also fully secured at the instant, at which the book block 10 gets between the plate chain or belt conveyor track 1 and 1'. In this case, the outer leaves of the book block 10 cannot remain behind as hitherto and are consequently not displaced. Advantageously, the book block 10 is thus securely gripped in tinobjectionably aligned state by the plate chain or belt conveyor track 1 and 1'.
In Fig. 3, the book block guide surfaces 12 and 12' engage into the effective clamping region of a plate chain or belt conveyor track 11 and 11'. The plate chains or conveyor belts are in this case arranged above and/or below the book block guide surfaces. For reasons of clarity, the plate chain or belt conveyor track 11 and 11' is interrupted in the illustration shown in Fig. 3. The book block guide surfaces 12 and 12' are conically arranged so that their spacing to each other reduces forwardly, i.e.
in book block conveying direction. They may, however, in a not illustrated manner also be bent away in such a manner that in the region of the book block. inlet, they at first run obliquely to the inlet direction and then parallel to this. Beyond that, the book block guide surfaces 12 and 12' are provided with a prolonged book block inlet 13 and 13', which introduces a supplied book block 14 with certainty between the book block guide surfaces 12 and 12'.
It is also possible to combine the embodiment of Fig. 1 with that of Fig. 3 if desired.
Thus, the book block guide surfaces 2 may engage into the effective clamping region of the plate chains or belt conveyor track or they may be arranged conically.
All the constructions may also be provided with a straight or bent away, prolonged book block inlet.
The unbound book blocks consisting of individual leaves or layers are, as hereinbefore described, gripped by the plate chain or belt conveyor track completely free of displacement even at high conveying speed so that the maximum possible performance is utilisable for the book block processing.
The air blast jets may be connected to one or more air blast feeds, and may, advantageously be stationed in book block guide surfaces. In the embodiments described, the air blast, which issues out of the air blast jets and the strength of which may also be regulable, presses on the outer book block surfaces so that the book blocks are compressed in the manner of tongs during the conveying flow. A displacement of the individual leaves or layers to one another may, advantageously, be thereby excluded. Furthermore, an air cushion, which appreciably reduces the friction, arises between the outer leaves and the book block guide surfaces. The book blocks thus remain fully maintained in their aligned shape during the introduction between the plate chain or belt conveyor tracks.
The book block guide surfaces may also be arranged conically in book block conveying direction in such a manner that their spacing from each other reduces forwardly, i.e. in book block conveying direction. Thereby, the security of the trouble-free book block entry may be increased.
It may also be advantageous to make the book block guide surfaces inclusive of the 'air blast jets settable in direction of the book block surfaces, i.e. in the spacing to each other, and/or in direction of the plate chain or belt conveyor track or also in respect of their conicality. In respect of the change of the spacing to each other, the setting-up of the device to different book block formats is possible thereby. Means known in themselves are provided for the adjustment itself.
In the normal case, the book block guide surfaces inclusive of the air blast jets, seen in conveying direction of the book blocks, are guided closely up to the effective clamping region of the plate chain or belt conveyor track.
The construction may however also be so arranged that they, inclusive of the air blast jets, extend into the effective clamping region of the plate chain or belt conveyor track.
Thereby, the displacement-free introduction of the book blocks is still favoured.
WHAT WE CLAIM IS: 1. Apparatus to grip an unbound book block comprising a plurality of leaves, the apparatus comprising conveyor means to grippingly receive and. convey the book block along a given direction, and air nozzles arranged in such a manner at an input region of the conveyor means for receiving the book block as in use to direct an air current at the two outer faces of the book block.
