Problems solved by technology

However, such devices with stack lifts require manual intervention during format changes
[0004] On known stacking devices, it is particularly disadvantageous that the back length of the printed products to be stacked, that is to say the back length of the corresponding stack, is limited by adjustable flaps. , these flaps have to be opened and closed, which on the one hand means high loads and on the other hand increases cycle times (Zykluszeit)

Embodiment Construction

[0023] exist figure 1 with figure 2 The stacking device 1 shown in has a frame 2 with an approximately horizontal table 3 on which two endless drives 4 , 5 are supported. Arranged in the recess 35 of the table 3 is a lift 12 with two inner lift plates 13 and two outer lift plates 14 . Can be formed on this lift 12 Figure 3a to Figure 3d A stack 8 of printed products 9 is shown schematically in , wherein a lift 12 makes it possible to reduce the fall height of the printed products 9 . The stack 8 can consist of layers of printed products 9 which are each rotated by 180° relative to each other. For stacking, the table 3 can be rotated about a vertical axis by means of a servo cylinder 11 . This is known as so-called cross placement and is well known to those skilled in the art.

[0024] The stack 8 formed in this way can be squeezed, ie compacted, by raising the lift 12 against the press flap 20 . exist figure 2 Shown are two pressure flaps 20 arranged pivotably inward...

Abstract

The invention relates to a stacking device for printed products. The device has a rotatable table (3) on which printed products are stackable. Two ejector elements (6, 7) are applied at a printed product stack formed on the table to selectively push the stack from the table in opposite ejection directions. Two drive elements (6, 7) move the ejector elements independent of each other, and the ejector elements are rotatable along with the table. The ejector elements are driven by a motor (10), and are adjustable for adapting to a back length of the stack to be ejected.

Description

technical field [0001] The invention relates to a stacking device (Stapelvorrichtung) for printed products (Druckprodukte) with a table (Tisch) on which printed products can be stacked; and with at least two ejection mechanisms (Ausstossorganen), the push-out mechanisms can each be attached to the stacks (Stapels) formed on the table, and, with these push-out mechanisms, the formed stacks can be pushed away from the table; and, with The drive mechanism for the movement of the two push-out mechanisms. Background technique [0002] A stacking device of this type is known in the prior art from document US 5,868,548. On a rotatable table, it has two chains running endlessly (endlos), to which two finger-like ejection mechanisms protruding upwards are each fastened. The stack can be pushed off (weggeschoben) and pushed out (ausgestossen) from the table by a simultaneous movement of a push-out mechanism of each of the two chains. Since the stack abuts simultaneously on both eje...
