Definitions
- spindle drives have been used for this purpose, which due to their pitch have the advantage of a small stroke movement with a relatively large rotary movement.
- a disadvantage of such spindle drives is the relatively high construction effort associated with corresponding costs. The same applies to transmissions that have become known in these applications, in which a rotating pinion meshes with a toothed rack.
- Rope or chain systems that are attached to the vertically guided stacking compartment and are pulled or rotated by a drive motor are cheaper and therefore used relatively frequently in order to vertically adjust the stacking compartment in the desired manner.
- stacking compartment for sheet-like recording media which is relatively difficult with a corresponding stacking capacity. This is especially true if the stacking tray. should preferably only be guided from one wall side in order to gain the greatest possible design freedom, for example also in the arrangement of a plurality of such stacking compartments.
- a stacking compartment for sheet-like recording medium 1 is shown in an exploded view. It is therefore also not shown whether this stacking compartment is to be used as an input or output compartment for sheet-shaped recording media, because this purpose is not important in itself. It is only assumed that this stacking compartment must be adjustable in its vertical position, for example to a certain level of the stacked surface of the sheet To keep record carrier 1 constant, although the stack height is constantly changing.
- the first guide groove 7 serves for the vertical guidance of the end wall 2 of the stacking compartment, which is designed as a slide.
- This end wall therefore has bearing pins 9 and 10 protruding at right angles from its narrow sides with ball bearings 11 arranged thereon.
- the bearing pins 9 and 10 assigned in pairs to the narrow sides of the end wall 2 with the ball bearings 11 arranged thereon preferably have a sufficient axial distance from one another. Because in the assembled State of the stacking compartment, the ball bearings 11 each run into one of the first guide grooves 7 of the guide rails 4.
- a sufficient radial distance between the first pairs of trunnions 9 and 10 ensures reliable guidance of the end wall 2 of the stacking compartment in the first guide grooves 7, even though that on the end wall 2 attached and the stack of record carrier tray 3 on this ball bearing 11 exert a corresponding torque.
- the compensating motor is not mechanically connected to the height-adjustable part of the stacking compartment, preferably fixed on the carriage 2, in the schematic representation of FIG. 3. It is designed as a clocked gear motor that inhibits itself. This ensures the current vertical position of the stacking tray.
- a sensor 22 is provided assigned to the surface of the stack of the sheet-shaped recording media 1, as is shown schematically in FIG. This scans the vertical position of the stack surface. This sensor 22 is thus used as a level switch, it emits a signal with a tolerance of approximately 10 sheet-shaped recording media 1, which is supplied to the compensating motor 20 as a control clock signal for a counterbalancing compensating movement.
