Apparatus for lifting successive topmost stacks of large paper sheets and the panels beneath such stacks off a pile of superimposed stacks and panels has one or more separating units each employing a roller which is caused to bear upon the topmost sheet of the topmost stack of the pile and a sword which is aligned with or is disposed at a level slightly below the topmost panel of the pile and is caused to penetrate into the pile so as to lift the topmost stack with the topmost panel preparatory to automatic shifting of the lifted stack and panel sideways into a processing machine. The distance between the lowermost portion of the roller and the plane of the sword is adjustable to permit for subdivision of piles having thicker or thinner stacks. Any sheets which are lifted with a panel and belong to the stack below the lifted panel are stripped off the lifted panel by a continuously driven friction wheel which enters the gap that is formed by the sword. A hold-down device is employed to press upon the stack below the gap during transfer of the lifted stack and panel into the processing machine.
Apparatus for subdividing a pile of superimposed stacks of sheets wherein each stack has a predetermined thickness and rests on a planar bottom panel of paperboard or the like, comprising separating means including at least one separating unit having a device for applying to the pile mechanical pressure from above, a separating element disposed in a plane which is parallel to the planes of bottom panels in the pile and is arranged to penetrate into the pile at a level below said device, distancing means for maintaining said device and said separating element in spaced-apart positions at at a mutual distance at least matching said predetermined thickness, and means for moving said device in a substantially vertical plane toward engagement with the topmost stack of the pile and for moving said separating element in a substantially horizontal plane penetrating into the panel beneath the topmost stack of the pile.
Apparatus for subdividing a pile of superimposed stacks of sheets wherein each stack has a predetermined thickness and rests on a planar bottom panel of paperboard or the like, comprising separating means including at least one separating unit having a device for applying to the pile mechanical pressure from above, a separating element disposed in a plane which is parallel to the planes of bottom panels in the pile and is arranged to penetrate into the pile at a level below said device, distancing means for maintaining said device and said separating element in spaced-apart positions at a mutual distance at least matching said predetermined thickness, and means for stripping surplus sheets off the underside of the panel beneath the topmost stack of the pile if and when said separating element penetrates into the pile beneath the panel which is disposed immediately below the topmost stack of the pile.
Apparatus for subdividing a pile of superimposed stacks of sheets wherein each stack has a predetermined thickness and rests on a planar bottom panel of paper board or the like, comprising separating means including at least one separating unit having a device for applying to the pile mechanical pressure from above, a separating element disposed in a plane which is parallel to the planes of bottom panels in the pile and is arranged to penetrate into the pile at a level below said device, distancing means for maintaining said device and said separating element in spaced-apart positions at a mutual distance at least matching said predetermined thickness, means for shifting the separated topmost stack of the pile and the panel beneath the topmost stack with reference to the next-to-the-uppermost stack of the pile, a hold-down device movable against the topmost sheet of the next-to-the-uppermost stack of the pile upon penetration of said separating element into the pile beneath the topmost stack, means for moving said pressure applying device and said separating element, means for moving said shifting means, for moving said hold-down device, and a common support for said moving means.
Apparatus for subdividing a pile of superimposed stacks of sheets wherein each stack has a predetermined thickness and rests on a planar bottom panel of paper board or the like, comprising separating means including a plurality of separating units which are spaced apart from one another and each of which has a device for applying to the pile mechanical pressure from above, a separating element disposed in a plane which is parallel to the planes of bottom panels in the pile and is arranged to penetrate into the pile at a level below the respective device, and distancing means for maintaining the respective device and the respective separating element in space-apart positions at a mutual distance at least matching said predetermined thickness;
