Abstract
An apparatus for infeeding printed products or the like to a stacker, comprising an endless revolving conveyor having an outfeed portion which is elevationally adjustable and automatically accommodatable to the height of the formed stack. The outfeed portion is constituted by a loop of an essentially vertically traveling run of the conveyor, the loop is deflected out of the conveyor by means of guides which are arranged at a frame guided along the aforementioned run and displaceable by means of a lift drive. The lift drive can be switched-on and switched-off as a function of the response of a feeler provided at the frame and scanning the height of the stack.
Claims11
An apparatus for delivering an imbricated stream of printed products to a stacker, comprising an infeed station, an outfeed station and a conveyor extending between said stations, said conveyor being provided with spaced grippers for laterally gripping the imbricated stream of printed products, said conveyor comprising a substantially vertically travelling run, said outfeed station comprising means for deflecting a loop out of said run, said loop having a leg terminating at an apex of said loop, opening means positioned in the range of said leg for opening the grippers, a conveyor belt running parallel to said leg for receiving the imbricated stream of printed products thereon and having an outfeed portion extending past said apex of said loop, means for driving said conveyor and said conveyor belt in synchronism, said guide means, opening means and said conveyor belt being mounted in a frame, a lift drive for displacing and guiding said frame along said vertically travelling run, said frame being provided with a feeler for scanning the height of the stack and for switching-on and switching-off said lift drive as a function of the response of said feeler.
An apparatus for infeeding printed products to a stacker comprising an endless revolving conveyor having an outfeed portion, the conveyor comprising a conveying element having a run which travels essentially vertically, guide means for deflecting a loop out of the vertically travelling run of the conveying element, said loop defining said outfeed portion of the conveyor, means for elevationally adjusting said outfeed portion and automatically accommodating the same to the height of the formed stack, said adjusting means comprising a frame, a lift drive for displacing the frame and guiding the same along said run of the conveying element, said guide means being arranged at said frame, a feeler provided at the frame for scanning the height of the stack and switching-on and switching-off the lift drive as a function of the response of the feeler, said conveyor possessing a predetermined conveying direction, grippers provided for said conveyor and arranged in spaced relationship from one another in the conveying direction of the conveyor, said grippers serving to seize the lateral edges of the printed products, said conveyor comprising two substantially parallel revolving chains, each of said chains being equipped with said grippers, said loop having a leg terminating at an apex of the loop, a conveyor band extending substantially parallel to said leg of said loop, said conveyor band being arranged at the region of the loop and between said chains, said conveyor band having an outfeed portion extending past said apex of said loop.
