Conveyor system, in particular for printed matter

The invention relates to a system for conveying plate-shaped, flexible materials, in particular in the form of printed matter such as newspapers, magazines, leaflets etc., which arise continuously from a processing station, e.g. a rotary or folding machine, in brought a partially overlapping layer and carried away in a flaky strand.

609850/0582

A system of this type is, for example, from the DT-Ao 1 039 5 ^ 0 and consists essentially of a sequence Carrier transverse to the conveying direction with spring-loaded gripping devices arranged at the ends and a revolving conveyor chain connecting the carriers to form an endless conveyor line.

There. On the one hand, printed products very often in their external dimensions, So change their paper format, on the other hand, when fresh off the press, only on the unprinted, narrow ones The main disadvantage of this known system lies in the fact that, due to the mutually invariable Distance between the grippers either only approximately the same paper formats can be conveyed or long downtimes are required to convert such a system.

The object of the present invention is therefore to provide a printing machine or the like. to create subsequent sponsors, with which the continuous and gentle removal of printed products with a format width of, for example 200 to 5OO mm becomes possible without the need for changeover times or a system shutdown is required.

This object is achieved by the technical means specified in the patent claims and their mutual cooperation.

In the drawings are exemplary embodiments of the invention and their function is described in more detail below.

Show it:

1 shows a cross section through the system in the transport state,

Fig. 2 shows the same cross-section, but with the open Grippers,

FIG. 3 shows a cross section like FIG. 1, but with changed gripper spacing and

4 shows a gripping device as a detail on an enlarged scale.

The system consists of the guide rails 2, 3j connected to one another via a support 1, the guide rollers acting on them, or fiollenpaaren 4, 5 and the den 4, 5 as well as the arms 9 of the cross member receiving center piece 6 on the at the same time the angularly bent outer links 7 and between these, the inner links 8 of the revolving endless chain 7, 8 are attached. Also on the middle piece 6 are elastic Support strips 10 attached to the central support of the objects to be conveyed 11, which at their edge areas 12 by the spherical holder 13 via springs 14 on the support surface 15 of the gripper console 16 are held.

At least one, but advantageously both, of the consoles 16 each cross member 6, 9 are axially displaceable, arrow 21, mounted on the arms 9, with 17 ball thrust pieces via screw connections 18 are inserted into the bottom 19 of the consoles 16, which can snap into corresponding recesses 20 of the arms 9. Corresponding to the position of the schematically indicated control cams 22, as FIG. 3 shows, the consoles 16, the Via recesses 23 in the control cams 22 on the not shown Diverting stations run in axially automatically at different distances between the grippers 13 set while the system continues to run.

The opening of the gripper 13 according to FIG. 2 also takes place via control cams 24, which act on the sliding rollers 25 of the racks 26, the _Si y from the closed dimension "x" to "x ¹ " in the

Press down channel 27, and under tension of the spring 14 the convex holder 13 in cooperation with lever 30 and toothed segment 28 move up about the pivot axis 29. Due to the force acting perpendicular to the longitudinal axis during this adjustment process the arms 9i isfc ensures that the ball thrust pieces 18 do not get any axial forces in the recesses 20 of the arms 9 and stay in the preset distance from each other.
