Definitions
- the invention relates to depositing a sheet of paper onto a stack of sheets, preferably for use in a printing press, particularly an electrographically operating press, where the sheet to be deposited is grasped by at least one rotationally drivable sheet conveyor member with the front edge of the sheet fed into a receptacle, and to deposit on the stack of sheets, the sheets' front edge is released from a receptacle, preferably through the use of a stop, particularly, a stack edge.
- Rotational sheet conveyors for feeding sheets into a receptacle for stacking are identified in DE-A-23 09 075.
- the underlying objective of the invention is to carry out a controlled depositing of the sheet of paper onto the stack of sheets.
- this objective is achieved by causing the sheet's front edge to be released from the receptacle of the rotating sheet conveyor member prior to the depositing of the sheet onto the stack of sheets, and instead, it is deposited into a receptacle of an intermediate transport member, where it is further released for depositing onto the stack of sheets.
- An intermediate transport member is therefore beneficially provided, according to the invention that is particularly suitable for controlled depositing.
- the intermediate transport member with a receptacle for the deposit of the front edge of the sheet of paper is arranged so that the sheet's front edge can be passed out of the receptacle of the sheet conveyor member into the receptacle of the intermediate transport member, preferably through the rotation of the sheet conveyor member.
- a stop particularly, a stack edge, with respect to which the intermediate member is movable relative to a sliding out of the sheet front edge out of its receptacle.
- no separate drive is provided that would require coordination with the drive or with the rotary position of the sheet conveyor member.
- a beneficial automatic control of the movement processes results if the intermediate transport member is coupled with the rotationally drivable sheet conveyor member for mobility.
- the timing of the processes and movement directions can be easily mechanically coordinated with each another.
- at least one curved path that rotates with the sheet conveyor member is provided, preferably a cam plate.
- a more preferable arrangement of the apparatus, according to the invention, can be provided so that the intermediate transport member is suspended movably by a lever assembly with, preferably at least one of the lever arms of the lever assembly, being supported movably on at least one curved path, at least indirectly via an intermediate element.
- the lever assembly includes an essentially horizontally oriented level arm and an essentially vertically oriented level arm that are connected to each other with play remaining, and a separate curved path is provided in each case to allow for their movement processes.
- the apparatus is preferably configured so that the intermediate transport member or coupling elements provided are spring-fitted.
- FIG. 1 is an apparatus according to the invention in a lateral view; and FIG.
- FIG. 1 shows an apparatus according to the invention, schematically in a lateral view.
- the apparatus includes a rotationally drivable sheet conveyor member 1 that has two slot-shaped receptacles for sheet's front edges that are arranged in a manner where they are diametrically opposed to one another. Coaxially arranged cam plates 10, 11 rotate with the sheet conveyor member.
- the apparatus includes the lever arm assembly with a horizontal lever arm 2 and a vertical lever arm 3. The vertical lever arm 3 is suspended in a movably swinging manner on the horizontal lever arm 2.
- the lever arm 2 is controllably supported on the cam plate 10 with a ball bearing 6, and is rotatably attached at a pivot 4.
- the lever arm 3 controllably abuts onto the cam plate 11. Springs 13 and 19 ensure the secure respective abutments of the lever arms.
- the system is arranged on a mount 14.
- a sheet 9, to be deposited on a stack 12 arrives from a path for print material and reaches the last transport rollers 8 of the path. These transport rollers 8 pass the sheet 9 to the sheet conveyor member 1 by pushing it into a free slot of the sheet conveyor member 1. However, the sheet 9 is not released directly onto the stack 12 from the sheet conveyor member 1.
- the vertical lever arm 3 At the lower end of the vertical lever arm 3, instead, there is a gripper mouth 15 that acts as an intermediate transport mechanism for the sheet 9.
- the sheet 9 is passed into this gripper mouth 15 through the rotation of the sheet conveyor member 1. Due to the eccentricity of the cam plate 11, during further rotation of the sheet conveyor member, the vertical lever arm 3 endures a pendulum swing (to the left, in the representation in the drawing) about the pivot 7. In this manner, the gripper mouth 15 moves relatively through a stack edge 16, where the sheet is slid out of the gripper mouth 15, and thereafter it falls onto the stack 12.
- the pendulum movement of the vertical lever arm 3 occurs against the spring force of a spring 17 that vertically pulls the lever arm 3 in the play 5 downward, and adapts to the stack height.
- FIG. 2 shows a detailed view of FIG. 1. Identical components are designated with the same reference numbers as in FIG. 1.
- the gripper mouth 15 has two clamping elements 20, 21.
- the movement process of the apparatus can be briefly described as follows: During rotation of the sheet conveyor member 1, the installed cam plates 10, 11 participate in the movement. If a sheet 9, to be deposited, was conveyed via the sheet conveyor member 1 against the stack edge 16, then this sheet 9 has simultaneously threaded into the gripper mouth 15. After the sheet conveyor member 1 is rotated out of the region of the sheet 9, the gripper mouth 15 is lowered over the cam plate 10. Finally, the gripper mouth 15 is placed on the stack 12. In order to compensate for differences in height in the stack 12, an elongated hole guide 5 is located on the vertical lever arm 3. The tension spring 17 ensures that the gripper mouth 15 is actually resting on the stack 12.
- the gripper mouth 15 In the next step in the representation, the gripper mouth 15 must now proceed through the stack edge 16, while being moved away to the left. This is accomplished via the cam plate 11.
- the cam plate 11 deflects the vertical lever arm 3 over the pivot 7, to the left.
- the gripper mouth is installed in a spring-fitted manner on the vertical lever arm 3. As a consequence, the gripper mouth 15 remains horizontally oriented during the lateral swinging.
- the sheet 9 can thus be concisely released over the stack 12.
- the benefit with this additional device, on the sheet conveyor member is that the sheet is still reliably deposited on a stack, even in the case of a skewed stack surface.
