includes with perpendicular to the conveying direction of the first conveyor track disk axis, while the other triangle of the All-side roller field only all-side rollers with the direction of conveyance the second conveyor track has a vertical disk axis, according to patent. . . (Patent application P 25 15 009.8-22}.

Omnidirectional rollers of the type noted above are disclosed in U.S. Patent. 36 21 961 shown. A ^ square Converter of the type described is evident from DT-OS 25 15 009.

The size of the known converter depends on the area of the material to be handled, so that different converters are to be made for different purposes.

The invention aims to expand the basic idea of the known converter to the effect that conveyed material different, especially very large, floor space can be implemented without having to have a correspondingly large one Having to redesign and manufacture converters.

The problem arises particularly when conveying large panels such as chipboard, which have an elongated rectangular base, arrive in the longitudinal direction on a production line and must be withdrawn from this side on a stack.

The solution according to the invention is that several converters of the same design in the same arrangement in one plane to a converting field with a larger base area are joined together.

As a result, a standard size of individual converters can essentially be produced practically in series in order to achieve a modular unit that is adapted to the base area of the material to be conveyed.

809881/0413

The essence of the invention lies in the enlargement of the converting base area by adding the same Arrangement acting individual repositioning ·]. This is different from the sequential arrangement of several converters in different arrangements, around one Multiple angled Uninetzweg to reach.

The omnidirectional rollers are expediently driven together in at least one axial direction of several individual converters, so that the drive expenditure for the unit can be reduced.

Exemplary embodiments of the invention are shown in the drawing.

1 shows a side view, FIG. 2 shows a front view of the omnidirectional rollers used;

Fig. 3 shows a plan view of a transfer unit according to the invention, which is two in width and three in length Converter includes;

Figs. 4 and 5 show further possible thematically Merging of individual converters to form a larger converting unit.

The omnidirectional roller 10 shown in FIGS. 1 and 2 comprises a bearing disk arranged on a shaft 1 2, the 3 pairs of parallel opposite bearing lugs on both sides in the axial direction 3 carries, on which on a shaft journal 4, which leaves 1 distance to the shaft and perpendicular to this stands, a barrel-shaped roller 5 is rotatably mounted about its axis. So on each side there are three barrel-shaped ones Rollers 5 are provided, wherein the rollers 5 are arranged offset from one another by 60 ° in the circumferential direction and just overlap at the ends.

809861/0413

The limits of the rollers 5 in one through the axis guided cross-section are arcs of a circle. The arrangement and dimensioning is made so that, as is best from FIG. 2 shows the circular arcs representing the outer circumference to form a circular circumference 6 merge. The omnidirectional roller 10 therefore rolls around the shaft 1 without a step. But at the same time The omnidirectional roller 10 can roll in the direction of the shaft 1 by the eii .ein barrel-shaped rollers rotate on their axes. The omnidirectional roller 10 can therefore be moved rolling in all directions.

The conversion unit shown in FIG. 3 and designated as a whole by 100 comprises 6 individual converters 20 of square base.

The lower right converter 20 in FIG. 3 is described as an example. He can do that at first Conveyor track 11 in the direction of arrow 12 incoming conveyed goods onto a conveyor track branching off at right angles therefrom 13 to implement in the direction of arrow 14. The conveyor tracks 11, 13 are in the embodiment designed as roller conveyors, but can also be conveyor belts or the like, for example.

The converter 20 comprises a square frame 15 _y in which several omnidirectional rollers 10 are mounted on shafts 1. The entire omnidirectional roller field covering the base area of the converter 20 is divided diagonally. The diagonal & runs according to FIG. 3 from the bottom right to the top left. The triangle 16 adjoining the conveyor track 11 with one side has

Shafts 1 which are parallel to the roller axes of the conveyor track 11. The triangle 16 tapers in the direction 12 away from the second conveyor track 13, i.e. each

is further advanced in the direction 12, the more Axis 1 becomes shorter and the fewer rollers there are on the individual axes 1. 1 'are the waves that run parallel to the rollers of the conveyor track 13.

The shafts 1 and 1 'are each outside in the frame of the converter 20 and inside, i.e. on the diagonal ^ in Bearing blocks 18 rotatably mounted. On the outside, the shafts 1,1 'carry double chain wheels 19, from which alternate with successive waves 1, 1 ' the inner and outer are connected to one another by chains 21.

In the case of a single converter 20, the conveyed material runs in the direction of arrow 12 and is passed through the omnidirectional rollers 10 are further conveyed on the axles 1 until it comes to the limit of the converter 20, where at a switch is located in a single converter, which is actuated by the material being pushed and the drive of the omnidirectional rollers 10 of the triangle 16 and the drive of the omnidirectional rollers 10 of the triangle turns on. The material to be conveyed is then conveyed in the direction of arrow 14 by the drive the omnidirectional rollers 10 seated on the shafts 1 '. The conveyed material is not oriented in its orientation offset, because the removal of the conveyed material from the omnidirectional rollers 10 of the triangle 16 in the axial direction, i.e. with the rotation of the rollers 5 about their axes and thus with practically no resistance.

In Fig. 3 there are now six such converters 20 with the same design and arrangement as a whole designated transfer unit assembled. The base of the relocating unit 100 corresponds to two relocators

809881/0413

in width and three in length. For example, by assembling converters 20 uniform design transfer units of any size can be put together. It runs e.g. a chipboard whose width corresponds to twice the width of a single converter 20, over all converters 2O up to a limit switch provided in the upper edge housing 22 of the converting unit 1OO before. The omnidirectional rollers 10 of all triangles 16 drive the chipboard forward. Upon impact A limit switch is actuated on the edge housing 22, which switches off the drive of the omnidirectional rollers 10 of the triangles 16 and turns on the drive of the omnidirectional rollers 10 of the triangles 17, which then take over the promotion and pull off the chipboard transversely in the direction of arrow 14 from the transfer unit 100. In the embodiment are two adjacent conveyor tracks 11 for the conveying direction 12, for the conveying direction 14 three adjacent conveyor tracks 13 are provided. This can be for standardization and avoidance reasons roles that are too long and therefore susceptible to sagging should be useful, but it is by no means mandatory. For example, there can also be continuous rollers or such a roller across the width of the two conveyor tracks 11 Conveyor belt can be used.

The chain wheels 19 of different converters 20 lying in a line 23 or 24 are each driven together, so that the drive effort reduced and not required for each individual converter 20 separate drives for the two directions are.

Tn Fig. 4 shows a further embodiment for particularly long conveyed material is shown, which four series-connected converter 20 comprises, which are arranged the same among each other and to which the Material to be conveyed runs up in the direction of arrow 26 and from which it is deducted in the direction of arrow 27.

Fig. 5 shows a further embodiment in which four converters 20 are provided in a square arrangement are. .

It goes without saying that the relocating units, insofar as they have an elongated rectangular plan, also vice versa be able to work, i.e. take over the conveyed goods with the longer side and deliver in the longitudinal direction can.
