Device for supplying printed products to a processing section

Abstract

An apparatus for separating and removing a flexible flat object, such as a printed product, from an underside of a stack of flexible flat objects, and for supplying the objects to a processing section, includes a conveying rotor having a central axis, a shaft arranged concentrically with the central axis and at least one separating element located in a circumferential region of the conveying rotor to respectively lift at least partially one of the flexible flat objects from the stack and deposit the object in a region of the circumference of the conveying rotor. The separating element includes a suction mount pivotally arranged on the conveying rotor and positioned at a distance from and parallel to the shaft; a suction head attached to the suction mount to pivot with the suction head and to grip the flexible flat object with a suction force; an activation mechanism to control a pivoting movement of the suction mount when an object is partially lifted from an end of the stack; a joint coupled to the suction mount; and a control device connected to the joint to effect a further pivoting movement of the suction mount.

1 . An apparatus for separating and removing a flexible flat object, such as a printed product, from an underside of a stack of flexible flat objects, and for supplying the objects to a processing section, comprising:
 a conveying rotor including a central axis, a shaft arranged concentrically with the central axis and at least one separating element located in a circumferential region of the conveying rotor to respectively lift at least partially one of the flexible flat objects from the stack and deposit the object in a region of the circumference of the conveying rotor, the separating element including:
 a suction mount pivotally arranged on the conveying rotor and positioned at a distance from and parallel to the shaft; 
 a suction head attached to the suction mount to pivot with the suction head and to grip the flexible flat object with a suction force; 
 an activation mechanism to control a pivoting movement of the suction mount when an object is partially lifted from an end of the stack; 
 a joint coupled to the suction mount; and 
 a control device connected to the joint to effect a further pivoting movement of the suction mount. 
   
   
   
       2 . The apparatus according to  claim 1 , further including a lever gear connected to define the joint and coupling the suction mount to the activation mechanism to permit the further pivoting movement of the suction mount about the joint. 
   
   
       3 . The apparatus according to  claim 1 , wherein the suction head extends substantially at a right angle to a longitudinal extension of the suction mount. 
   
   
       4 . The apparatus according to  claim 1 , wherein the control device includes at least one cam curve that rotates along with the shaft of the conveying rotor. 
   
   
       5 . The apparatus according to the  claim 4 , wherein the control device includes at least one cam roller operatively coupled with the at least one cam curve. 
   
   
       6 . The apparatus according to  claim 5 , wherein the cam roller is arranged on the suction mount. 
   
   
       7 . The apparatus according to  claim 1 , wherein the additional pivoting movement of the suction mount around the joint is coordinated with the movement controlled by the activation mechanism. 
   
   
       8 . The apparatus according to  claim 7 , wherein the additional pivoting movement of the suction mount is coordinated with the movement controlled by the activation mechanism so that a suction surface of the suction head is oriented during one cycle interval toward the flexible flat object to be separated from the stack. 
   
   
       9 . A feeder comprising the apparatus according to  claim 1  to supply printed products to a gathering device or an inserting machine. 
   
   
       10 . A method of feeding printed products to a gathering device or an inserting machine, comprising utilizing the apparatus according to  claim 1 . 
   
   
       11 . The apparatus according to  claim 1 , wherein the suction mount and the shaft of the conveying rotor each including a channel for conducting a vacuum to the suction head, and the apparatus further includes a flexible line connecting the channels. 
   
   
       12 . The apparatus according to  claim 1 , wherein the activation mechanism comprises a pivotally mounted control shaft mounted spaced apart from and parallel to the shaft of the conveying rotor.
