Abstract
An apparatus for forming stacks of flat objects 12, in particular printed products, comprises a compartment 10 which is mounted for selective rotation about a vertical axis and whose compartment space 10′ is bounded on two mutually opposite sides by bounding elements 68, 72. In the ejection direction A, the compartment is bounded by upstream guide elements 66 and downstream guide elements 70. The flat objects 12 are fed to the compartment 10 from above and come to lie in a stack formed on the compartment base 28. The upstream guide elements 66 and downstream guide elements 70 can be moved independently of one another in order, firstly, to permit the ejection of the stack formed and, secondly, to permit the stacked objects 12 to be held firmly during the rotation of the compartment 10.
Claims17
An apparatus for forming stacks of flat objects, such as printed products, comprising
- a compartment which defines an upwardly open compartment space and which is bounded by a compartment base, at least one upstream guide element on the upstream side of the compartment space when viewed in an ejection direction, and at least one downstream guide element on the downstream side of the compartment space, and
- drive means for ejecting a stack of printed products from the compartment space in the ejection direction comprising a first drive for moving the upstream guide element through the compartment space in the ejection direction, and a second drive for moving the downstream guide element out of the compartment space, and wherein the first drive and the second drive are independently operable.
An apparatus for forming stacks of flat objects, such as printed products, comprising
- a compartment which defines an upwardly open compartment space and which is bounded by a compartment base upon which the flat objects are adapted to be received so as to form a stack thereof, a pair of bounding members forming the opposite lateral sides of the compartment space, at least one upstream guide element and at least one downstream guide element respectively forming the upstream and downstream sides of the compartment space when viewed in an ejection direction, said compartment base being mounted for rotation about a central vertical axis and the apparatus further comprises a drive for selectively rotating the compartment by about 180° about said axis, and
- drive means for selectively (1) moving the upstream guide element and the downstream guide element both in the ejection direction to eject a stack formed in the compartment, and (2) moving the upstream guide element and the downstream guide element toward each other to at least approximately bear against the stack being formed in the compartment in order to stabilize the stack during rotation of the compartment.
