Device for changing the direction of a product flow, particularly of paper products supplied in shingled formation

#This invention relates to a device for changing the direction of a product flow, particularly of paper products supplied in shingled formation having an inflow element, an accumulating plate and an outflow element.

#Handling paper products, particularly when these are conveyed multi-layer in shingled formation, often necessitates changing the direction of the product flow in the horizontal plane by a certain angle which is usually 90.degree. . This is true especially when the paper products are required to be cut or trimmed on three sides. For changing the direction of flow in this way, devices are used which usually feature a horizontal plate, an accumulator plate located vertical to the latter and provided adjustable on the horizontal plates and which may be provided with a diverter roll. Changing the direction of the product flow by 90.degree. is done on the table or on the mounting plate. To facilitate the change in the direction of flow and especially to prevent any change in the formation of the products it is prior art to provide for a change in the direction of the product flow first by 45.degree. immediately following the inflow before providing the further change in the direction of flow by a further 45.degree. . In this prior art device, however, it is not possible to adjust the angle of the change of direction.

#The object of the present invention is to change the direction of the product flow having an inflow of differing angular positions -- according to requirements.

#One embodiment of the invention, by way of example, will now be described and with reference to the accompanying drawing in which:

#FIG. 1 is a cross-sectional elevation through one embodiment of the invention,

#FIG. 2 is a cross-sectional elevation through one part of said embodiment on an enlargened scale and

#A rectangular frame 1 extending perpendicular to the plane of the drawing and one short side of which is shown, carries two shafts 2 and 3, which are driven in synchronism by means of an electric motor 5 via an endless belt 4. Said two shafts 2 and 3 are driven in synchronism via gearwheels 6 and 7 provided at one end of said shafts. Each shaft 2 and 3 mounts pairs of elements 8. At least two such pairs of elements must be provided; in conventional rotary cutting systems having an over-corner change of direction provided on the frame 1 in the inflow at least three, possibly four to five pairs of elements 8 are provided. The direction of the product flow from the feeder conveyor is indicated by the arrow 9.

#Each pair of elements comprises two essentially identical elements, of which the lower element 10 is locked to a rail 11 extended over the width of the frame and running vertical to the plane of the drawing. The longitudinal axis 12 of the lower element 10 runs horizontal. Each of the lower elements is secured equally spaced to the rail 11.

#The upper element 13 is located by its longitudinal axis 14 in an acute angle to the longitudinal axis 12 of the lower element; it is -- as detailed in the following -- spring-mounted and height-adjustable. In addition each element 13 can be swivelled also about the fulcrum 15 in the direction of the arrow 16.
