In The following figures are each the same or similar elements or corresponding parts provided with the same reference numerals, so that a corresponding renewed idea is ignored.

In the 1 to 3 are different working positions of a pliers drum 30 between a collection station designed as a collection station A and a receiving station E for paper stack shown in each case schematic side views.

The pliers drum 30 has on its circumference at two diametrically opposite points of the pliers drum 30 about pliers 15a . 15b , in pairs on the pliers drum 30 are formed. One or more pliers can be used to transport a stack of paper 15a . 15b on one side of the pliers drum 30 be arranged side by side in a kind of row.

Laterally is on both sides of the pliers drum 30 (see. 5 ) each have a linkage 25 arranged so that the pliers drum 30 a linear guided horizontal movement between the collecting station A and the receiving station E can perform. Between the joint gears 25 is the axis of rotation 32 the pliers drum 30 rotatably mounted, so that the pliers drum 30 Can perform rotational movements.

In the collecting station A are in accordance with the in 1 illustrated side view of several sheets of paper in a shingled stream of paper 5 promoted to the collection station A, in which the sheets are accumulated to a stack of superimposed flat parts or paper sheets. When processing a wide paper web by longitudinal cutting and cross cutting operations to paper sheets, the individual sheets of paper are conveyed in a plurality of webs side by side in the collection station A, where the sheets of each row are respectively accumulated to adjacent stacks.

At the in 1 illustrated working position of the pliers drum 30 becomes a paper stack present in the collection station A. 50a with the top or the top pliers 15a from the collection station A below the shingled paper stream 5 pulled out (arrow V). It holds a separating finger 10 while pulling out the paper stack 50a the incoming paper sheets of the scaly stream 5 back. The linear extraction of the paper stack 50a (Arrow V) via the linkage 25 so that the paper stack 50 via a horizontal movement of the pliers drum 30 is pulled out of the collection station A. This will be the paper stack 50a partially pulled out of the collection station A. This working position is in 2 shown schematically.

While at the in 1 illustrated working position of the pliers or pliers 15a for detecting a paper stack 50a at the collecting station A is at the bottom of the pliers drum 30 a second paper stack 50b on a storage table 60 the receiving station E arranged. Here, in a previous operation, the paper stack 50b from the pliers drum 30 have been transferred from the collection station A to the receiving station E. This was the paper stack 50b by opening a flap 20 from the dashed line position to rest on the table 60 brought.

In 2 is shown schematically in the side view of the working position, in which the top paper stack 50a that of the pliers or pliers 15a is detected, partially pulled out of the dispensing station A and to the flap 20 promoted. At the same time, at the bottom of the pliers drum 30 the paper stack 50b on the horizontal storage table 60 introduced into the receiving station E, so that subsequently the paper supplied to the receiving station E stack 50b from a removal facility 35 be detected and removed from the receiving station E.

By the horizontal movement of the pliers drum 30 and the collected paper stack 50a . 50b becomes the top paper stack 50a pulled out of the delivery station A, while the bottom paper stack 50b the receiving station E is delivered. This is done by a linear horizontal movement of the pliers drum 30 (see. 1 , Arrow V), while the pliers drum 30 is not rotated.

After complete insertion of the bottom paper stack 50b in the receiving station E is or will be the bottom pliers 15b solved, so that then the pliers drum 30 is placed in rotation. 2 schematically shows the working position of the pliers drum 30 after a first linear movement and before execution (arrow R) of the rotation about the axis of rotation 32 ,

By the subsequent rotation of the pliers drum 30 becomes the upper paper stack 50a completely pulled out of the dispensing station A. This is schematically in 3 shown in a side view.

To guide the paper stack 50a is a flap 20 on the pliers drum 30 arranged so that through the flap 20 the paper stack (s) pulled out 50a arcuate ge be bow. Here, the flap serves 20 to that the paper stacks 50a during the rotary movement of the pliers drum 30 are guided. Further, through the flap 20 the paper layers of the paper stack 50a held until the previously stretched paper layers are removed at or in the receiving station E from there.

After completion of the rotation by 180 ° of the pliers drum 30 becomes the flap 20 pivoted or controlled (see. 1 , Arrow W), so that the rotated paper layers stretched on the support table 60 rest. This is 1 for the marked paper stack 50b shown accordingly. During the rotary movement (arrow R) of the pliers drum 30 around the horizontal axis of rotation 32 is the forceps initially positioned at the bottom 15b (see. 1 . 2 ) turned upwards.

After the rotation of the pliers drum 30 180 °, so that now the pliers or pliers 15b at the top of the pliers drum 30 are arranged, the pliers drum 30 proceed horizontally to the delivery station A (cf. 3 , Arrow Z), so that the pliers 15b at the top into a next stack of paper sheets at collection station A, using the release finger 10 and / or a retainer 12 is formed at the collecting station A during the extraction of a paper stack from the collecting station A.

In addition, during the rotation of the pliers drum 30 after completely removing the detected paper stack 50a from the collection station A the pliers drum 30 from the receiving station E horizontally opposite to the conveying direction (arrow Z) for extracting the conveyor stack from the collecting station A (see. 1 ) moved back. This is in 3 indicated schematically.

By the pliers drum according to the invention 30 and a predetermined waveform and the linear reciprocating motion of the pliers drum 30 between the collecting station A and the receiving station E according to a horizontal travel previously extracted paper layers are inserted into the receiving station E, at the same time the upper next paper layers are pulled out of the collection station A. As a result, both short transfer paths and a high extraction capacity of paper stacks from the collection station A can be achieved.

In 4 is a front view of the pliers drum 30 shown schematically, wherein by means of the pliers drum 30 in multiple lanes several stacks of paper 50a be transferred from the collection station A in the receiving station E. For rotation of the pliers drum 30 is on the side of a lift arm of a linkage 25 a servomotor 45 arranged so that a superimposed and at the same time position-precise rotational movement of the pliers drum 30 is performed.

Within the scope of the invention, it is possible that the servomotor 45 stationary, preferably on a main frame, is arranged, wherein the servo motor by means of a propeller shaft and a flange, for. B. rotary flange, is connected to the lever arm.

It is also in 4 recognizable for transporting a pile of paper 50a two juxtaposed pliers 15a are provided, which in the recesses 11 the separating finger 10 at the bottom of the separating fingers 10 intervene to clear the paper stacks 50a to take in the collection station A.

In the 4 illustrated front view corresponds to the in 1 illustrated working position of the pliers drum 30 with the omission of the flap 20 (see. 1 ).

In addition, shows 5 in the plan view of the pliers drum 30 in the retracted state to the collection station A, that the pliers 15a the pliers drum 30 between the recesses 11 the separating finger 10 reach through a stack of paper below that of the release finger 10 Capture retained paper layers.

Furthermore, in 5 It can be seen that the paper stack delivered to the receiving station E 50b from the removal devices 35 be detected at the receiving station E and transversely or vertically, as the double arrow Q shows, are transported to the previous conveying direction of the paper stack from the receiving station E.
