Definitions
- the invention relates to a device for generating an offset of transported flexible flat material, in particular paper sheets, with one to and one discharging transport path section and an offset generating device assigned transport track section.
- Such a device for generating an offset can serve that in a delivery stack of a printing press a certain number of Sheets are stored offset, for example, the sheets of a job from which another job.
- an offset can also serve the Storage of individual flat goods to correct the exactness of the location in order to to get a flawless delivery pile.
- the invention is therefore based on the object of an easily adjustable device to make available of the type mentioned at the outset, which does not require a reset and works regardless of format.
- the offset generating device has at least two parallel reversing deflections, which can be brought to the transport direction at an angle ⁇ which is in the plane of the feeding transport track section measured or on this level projected is not 90 °. The latter affects the redirections that are not in the plane of the feeding conveyor track section.
- pairs of guide elements are arranged so that the sheets always held and transported on both sides by at least one pair of guide elements become. You can either on the outer edges, over the entire width or be held over the entire area.
- An expedient embodiment of the invention provides that the offset generating device is designed as a unit which can be pivoted by an angle ⁇ . there can be independent of the specific design of the offset generating device a joint swiveling of all the parts in total made for the generation of the offset must be pivoted.
- One embodiment provides that two deflections are provided, one Redirection to the opposite is. These two redirections can be called arcuate Guides be trained. It is possible that the two deflections Are strung together in an S-shape or there can be one between the two deflections flat transport track.
- An alternative embodiment provides that several deflections are provided, with at least two deflections in a first direction and at least two divert in opposite directions.
- This configuration has the advantage that less strong deflections required are. This is especially true for less flexible goods like cardboard advantageous.
- a similar effect is also achieved in that the arcuate Guides have a correspondingly large radius.
- the offset generating device assigned transport path section a level lying between the deflections Surface which is at an angle ⁇ of 90 ° to the other transport track sections runs.
- the adjustment by one Angle ⁇ to the direction of transport generates the greatest offset.
- the size of the Offset not only from the angle ⁇ but also from the distance h of the plane of the feed Transport track section depending on the level of the discharging transport track section.
- a further embodiment provides that the one assigned to the offset generating device Transport path section a surface lying between the deflections has, which is at an angle ⁇ of less than 90 ° to the other transport track sections runs.
- This configuration of the transport path of the offset generating devices as an inclined plane leads on the one hand to the fact that the offset achieved is smaller, but on the other hand this has the advantage that the deflections in one obtuse angles and therefore less flexible material by means of the Device can be moved, as is the case for example with thick papers or Carton is the case. It is a combination with several redirections or with Redirection possible with large radii.

- the conveyor belts can be designed such that a pair of conveyor belts Feeder, an angle-adjustable pair of conveyor belts generating the offset and a pair of conveyor belts is used for removal.
- transition guides are arranged on Transition from the feeding conveyor track section to the offset generating device and at the transition from the latter to the outgoing transport track section.
- transition guides must be designed in such a way that they participate in the angular adjustments in the intended angular range.
- the transition guide can consist of bars that have a pivotable linkage and have a sliding guide on the other side. This can be pivotally suspended or designed such that the rods are in it can pivot.
- further configurations are conceivable which take part in a swiveling movement, for example sheets which are fixed on one side and are mounted on the other side in a sliding guide.
- a particularly advantageous embodiment provides that a pair of conveyor belts extends over all transport track sections, each with a pair of rollers at the ends of the two conveyor belts for guiding and driving and in between one on the Transport belt pair acting offset generating device is arranged and wherein at least one of the pairs of rollers is designed such that it is the resulting Offset of the conveyor belts.

- This sequence applies to a transport direction in the direction of arrow 4, the sheet leading edge 22 being transported from right to left.
- An arrangement which applies to a reverse transport direction is designated with reference signs after the slashes. This means that the sheet trailing edge 23 then becomes the sheet leading edge 22 and the transport direction 4 reverses.
- the deflections 8 and 9 take place at the Transfer from one conveyor belt pair to the other, thus from the conveyor belt pair 18, 18 'to the conveyor belt pair 19, 19' and from this to the conveyor belt pair 20, 20 '. It is necessary that on the one hand there is enough space available for a Oblique positioning of the conveyor belts 19 and 19 ', on the other hand, this may Space should not be too large, so that the leading edge 22 of the tape is secure passed on to others. It can therefore be a transition guide similar to that above described. It is also possible that such a handover is avoided by providing only one pair of conveyor belts 17, 17 '. This is Subject of the following embodiments:
- Fig. 8 shows an embodiment with a single pair of conveyor belts 17, 17 '.
- the deflections 8, 9 take place by means of curved guides 11, 12.

If a sheet of flat material 3 is transported between the conveyor belts 17 and 17 ', this also experiences the offset 2 of the conveyor belts 17 and 17'. Since the conveyor belts 17 and 17 'rub against the guide surfaces 32 of the curved guides 11 and 12, the guide surfaces 32 must be provided with a very good, for example polished, surface.
- the advantage of guiding by means of a pair of conveyor belts 17, 17 ' is that the goods 3 are securely held and transported between these conveyor belts 17 and 17' regardless of the format size. Elements that serve the supply and removal of goods 3 have been omitted from the illustration. The following alternative embodiments serve to avoid the friction between conveyor belts 17, 17 ′ and the offset generating device 10:

- a deflection 8 is achieved by the deflection roller 40 'and the other deflection 9 by the deflection roller 40.
- An offset 2 is generated here in that the axes 41 and 41 'of the deflection rollers 40 and 40' are inclined by the angle ⁇ , as has already been explained with reference to FIG. 1.
- a transport direction 4 is possible in both directions, a good 3 being transported just as safely - as described in relation to FIG.
- FIG. 10 shows a perspective illustration of an exemplary embodiment which functions according to the principle already described for FIG. 9. The difference is that instead of the deflection rollers 40 and 40 ', several rollers 34 are provided. These rollers 34 are arranged such that they form two deflections 8 and 8 'in one direction and two deflections 9 and 9' working in opposite directions. Furthermore, rollers 34 also serve to return the conveyor belts 17 and 17 '. In this embodiment, all of the rollers 34 are arranged on the offset generating device 10, which is also pivotable about an axis 33.
- 10a shows a roller of a pair of rollers 53 and 53 ', which is designed as a rubber roller 43 with a slide bearing 44. It runs on a shaft 42 and can move on it in the direction of the double arrow 45.
- a pair of rollers 53 or 53 ' is displaced by the offset 2 as soon as this is generated by the fact that the offset generating device 10 is pivoted about the axis 33 mounted in the housing 26 by the angle ⁇ .
- 11a and 11b show a perspective illustration of an exemplary embodiment with a guideway 15 with curved guides 11 and 12, as has already been explained for FIG. 8.
- 11a shows a non-inclined offset generating device 10
- FIG. 11b shows the inclined offset generating device 10, this inclined position about the axis 33 being exaggerated.
- Guide roller pairs 13 and 13 ' also serve here for the feed to the offset generating device 10.
- the exemplary embodiments are mostly schematic representations that illustrate the principle should explain.
- the essence of the invention explained in relation to FIG Design forms can be realized.
