Splitting device
View Patent ↗A device for distributing successive products of a product flow, particularly the successive folding products produced by a cross cutting device by dividing a material web, to two branch flows, with a wedge arrangement which is arranged in a stationary manner in the transporting plane of the product flow and which engages between two cam rollers which flank it and which are arranged symmetrically with respect to the center working plane. The device is characterized in that the wedge arrangement engages between two guide plates which flank it and which, together with the wedge arrangement, define a path fork. The guide plates have slots through which they are alternately penetrated by cams of the respective adjacent cam roller which are associated with the slots, so that the penetrating cams and the guide plate which is not penetrated form a feed for a belt guide associated with a branch flow.
1. A device for distributing successive folding products produced by a cross cutting device by dividing a material web into two branch flows comprising:
a wedge arrangement arranged in a transporting plane of a product flow;
two cam rollers arranged symmetrically with respect to a center working plane that flank the wedge arrangement, each of the cam rollers having an associated plurality of cams;
two guide plates that flank the wedge arrangement configured to define a path fork with the wedge arrangement, each of the guide plates having a plurality of slots; and
a pair of rollers associated with a pair of belt guides configured to laterally deflect the folded product upstream of the guide plates;
wherein the guide plates are alternately penetrated by the plural cams of the respective adjacent cam rollers associated with the plural slots during rotation of the two cam rollers, wherein the penetrating cams and the one of the guide plates that is not penetrated form a feed for a belt guide associated with one of the branch flows.
2. The device according to claim 1 , wherein the two cam rollers have the plural cams arranged along their respective lengths in a closely spaced manner next to one another, and the guide plates have a plurality of slots corresponding with the plural cams.
3. The device according to claim 1 , wherein the wedge arrangement is vertically adjustable.
4. The device according to claim 2 , wherein the cam rollers are driven in opposite directions and are arranged in such a way that the plural cams of the two cam rollers face in the same direction.
5. The device according to claim 2 , wherein the plural cams of the two cam rollers extend over a circumferential segment of identical dimensions.
6. The device according to claim 1 , wherein the two cam rollers have continuous shafts on which are clamped a plurality of cam carriers each provided with the plural cams.
7. The device according to claim 1 , wherein each belt guide is associated with a branch flow having an outer transporting belt, configured for lateral guiding in an area downstream of the cam rollers and which is deflected in direction of the belt guide, and an inner transporting belt which is deflected downstream of and behind the wedge.
8. The device according to claim 1 , wherein the wedge arrangement comprises a plurality of wedges which are continuous at least over a width of the cam rollers a that is provided with a plurality of cams.
