Abstract

In some examples, a sheet processing machine includes at least one pile formation device. The at least one pile formation device is arranged in a vertical direction beneath a multiple-up separating mechanism. The at least one pile formation device is arranged so as to be displaceable at least in an inward-moving direction. The at least one pile formation device includes at least one horizontally displaceable pile formation means and a deposit element that can be displaced relative to the at least one pile formation means.

at least one deposit element ( 703 ) that can be displaced relative to the at least one pile formation means ( 705 ), wherein the at least one deposit element ( 703 ) is configured as at least one at least partially linearly configured transport means ( 703 ), and the at least one deposit element ( 703 ) is at least partially horizontally displaceable by at least one second drive ( 704 ), wherein the at least one pile formation means ( 705 ) and the at least one deposit element ( 703 ) are displaceable horizontally to a temporary storage position ( 724 ), wherein the at least one first drive ( 706 ) is configured to move the at least one pile formation means ( 705 ) away from the temporary storage position ( 724 ) while the at least one second drive ( 704 ) is configured to hold a region ( 721 ) of the at least one deposit element ( 703 ) stationary relative to the at least one pile formation means ( 705 ); and
a frame ( 733 ), wherein the at least one first drive ( 706 ) is fixed to the frame ( 733 ) and the at least one second drive ( 704 ) is fixed to the frame ( 733 ).

2. The sheet processing machine according to claim 1 , further comprising at least one coaxial shaft ( 731 ), wherein the at least one at least partially linearly configured transport means ( 703 ) and the at least one pile formation means ( 705 ) are displaceable relative to one another by means, at least in part, of the at least one coaxial shaft ( 731 ).

3. The sheet processing machine according to claim 1 , wherein the at least one at least partially linearly configured transport means ( 703 ) has a shorter length (l 703 ) than a length (l 705 ) of the at least one horizontally displaceable pile formation means ( 705 ).

4. The sheet processing machine according to claim 1 , wherein the at least one at least partially linearly configured transport means ( 703 ) is configured as a conveyor belt ( 703 ) comprising at least one deflection means ( 707 ).

5. The sheet processing machine according to claim 1 , further comprising:
at least one sheet insert unit ( 700 ) that comprises at least one intermediate sheet cartridge ( 702 ) for storing sheets ( 02 ), and
at least one transport element ( 717 ) that is arranged to at least partially lift a sheet ( 02 ) of the at least one intermediate sheet cartridge ( 702 ).

6. The sheet processing machine according to claim 1 , wherein:
the at least one pile formation means ( 705 ) comprises at least one fixed connecting element ( 711 ) that is fixed relative to the at least one pile formation means ( 705 ), and
the at least one fixed connecting element ( 711 ) is displaceably arranged with an at least partially horizontally guided guide element ( 712 ) that is functionally connected to the at least one first drive ( 706 ).

7. The sheet processing machine according to claim 1 , wherein:
the at least one at least partially linearly configured transport means ( 703 ) comprises at least one connecting element ( 713 ) that is fixed relative to the at least one at least partially linearly configured transport means ( 703 ), and
the at least one connecting element ( 713 ) is displaceable with an at least partially horizontally guided guide element ( 714 ) that is functionally connected to the at least one second drive ( 704 ).

8. A method for forming piles in a sheet processing machine ( 01 ) comprising at least one pile formation device ( 701 ), the at least one pile formation device ( 701 ) comprising at least one pile formation means ( 705 ) and at least one deposit element ( 703 ) that can be displaced relative to the at least one pile formation means ( 705 ), the method comprising:
inwardly moving the at least one pile formation device ( 701 ) in an inwardly-moving direction (E) from an inward-moving position ( 723 ) into a temporary storage position ( 724 ), and
outwardly moving the at least one pile formation device ( 701 ) from the temporary storage position ( 724 ) into an outwardly-moving position ( 726 ) counter to the inwardly-moving direction (E), wherein:
the at least one pile formation means ( 705 ) is at least horizontally displaced by at least one first drive ( 706 ),
the at least one deposit element ( 703 ) is at least partially horizontally displaceable by at least one second drive ( 704 ),
the at least one deposit element ( 703 ) is configured as at least one at least partially linearly configured transport means ( 703 ),
during the outwardly moving the at least one pile formation device ( 701 ) from the temporary storage position ( 724 ) into the outwardly-moving position ( 726 ), a relative movement takes place between the at least one deposit element ( 703 ) and the at least one pile formation means ( 705 ), wherein, during the relative movement, based at least on the at least one first drive ( 706 ) and the at least one second drive ( 704 ) being fixed to a frame ( 733 ) of the sheet processing machine, the least one first drive ( 706 ) moves the at least one pile formation means ( 705 ) to the outwardly-moving position ( 726 ), while the at least one second drive ( 704 ) holds a region ( 721 ) of the at least one deposit element ( 703 ) stationary.

9. The method according to claim 8 , wherein the at least one deposit element ( 703 ) and the at least one pile formation means ( 705 ) are displaced relative to one another by means, at least in part, of at least one coaxial shaft ( 731 ).

10. The method for forming piles according to claim 8 , wherein, during the outwardly moving, the relative movement takes place between the region ( 721 ) of the at least one deposit element ( 703 ) that is held stationary by the at least one second drive ( 704 ) and a further region ( 722 ) that is stationary relative to the at least one pile formation means ( 705 ) and that is displaced by the at least one first drive ( 706 ).

11. The method for forming piles according to claim 10 , wherein, during the outwardly moving the at least one pile formation device ( 701 ) from the temporary storage position ( 724 ) into the outwardly-moving position ( 726 ), at least one of:
the at least one region ( 721 ) of the at least one deposit element ( 703 ) that is held stationary by the at least one second drive ( 704 ) is held in position with respect to the inward-moving direction (E),
at least the further region ( 722 ) that is stationary relative to the at least one pile formation means ( 705 ) is displaced counter to the inward-moving direction (E), or
at least the stationary region ( 721 ) of the at least one deposit element ( 703 ) is held in position relative to at least one sheet ( 02 ) and a pile of multiple-ups ( 03 ).

12. The method for forming piles according to claim 8 , wherein, during a returning step to return the at least one pile formation device ( 701 ) from the outwardly-moving position ( 726 ) to the inward-moving position ( 723 ), the at least one pile formation means ( 705 ) and the at least one at least partially linearly configured transport means ( 703 ) are displaced relative to one another.
