Apparatus for overlapping and stacking sheets |
| 摘要 |
An apparatus for overlapping sheets and depositing them in a stack has a conveyor for transporting the sheets in a horizontal travel direction along a travel path toward a stacking region at a rapid feed speed. A braking device on the path upstream of the stacking region can grip the trailing edge of a one of the sheets. At least one supporting air bar extends above the path into the stacking region and has nozzles from which compressed air exits in the sheet travel direction. A suction belt above the travel path between the braking device and the stacking region is movable in the travel direction at least at the rapid feed speed and has suction ports that can be switched on and off cyclically. |

1. An apparatus for overlapping sheets and depositing them in a stack, the apparatus comprising:
conveyor means for transporting the sheets in a horizontal travel direction along a travel path toward a stacking region at a rapid feed speed; a braking device on the path upstream of the stacking region and capable of gripping the trailing edge of a one of the sheets; at least one supporting air bar that extends above the path into the stacking region and has nozzles from which compressed air exits in the sheet travel direction; a suction belt above the travel path between the braking device and the stacking region, movable in the travel direction at least at the rapid feed speed, and having suction ports that can be switched on and off cyclically; and a selectively switchable vacuum source and a selectively switchable positive pressure source connected to the suction belt. |
