ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device for transferring printed products from paddles of a rotating paddle or delivering form to grippers of a gripper chain type of printed product transport device.
DESCRIPTION OF THE PRIOR ART
A device is known from CH-PS 427 625, wherein the printed products are positively removed from the paddle wheels by means of a chain equipped with grippers. Here, several paddle wheels as well as a chain wheel are fastened on a common shaft and therefore rotate at the same speed.
Shortly after the printed products have been taken up by the grippers, in this prior art device the paddle wheel pockets are turned out of the area of the printed products held in the grippers. In this case, it is disadvantageous that the portion of the printed product located in the gripper jaws can be damaged while being turned out of the bottom of the paddle wheel pocket. This applies in particular to thick printed products.
SUMMARY OF THE INVENTION
The object of the present invention is directed to producing a device for transferring printed products out of a paddle wheel.
In accordance with the invention, this object is attained by the provision of a gripper chain or printed product traction device. The axes of rotation of the paddle wheel or delivery fan, and of the traction device drive wheel are located on a common axis of rotation. The paddle wheel or wheels, and the traction device drive wheel can be driven independently of each other.
The advantages which can be attained by the present invention rest in particular in that, after the transfer of a printed product to a gripper, the bottom of a paddle wheel pocket moves away from the front edge of the printed product before the paddle wheel pocket is turned out of the area of the printed product. In this way, the damage-free removal of the printed product from the paddle wheels and its transfer to a chain conveyor is assured by a compact and simple construction of the paddle wheel and chain drive.
