Definitions
- the invention relates to a stacking compartment for sheet-like recording media in a printing device with level control of the stack surface according to the preamble of the main claim.
- Height-adjustable stacking compartments for sheet-like recording media are known as such in a large number of applications. They can be used in the form of input compartments, in which the stacked record carriers are detached from the stack sheet by sheet with the aid of separating or removal devices and moved in the direction of a transport path of the printing device. In many cases, such separation devices are not designed to be pivotable, so that the stacking compartment has to perform a lifting movement in order to maintain the necessary frictional contact of the separation device with the stack surface as the stack height decreases.
- Such a height-adjustable stacking compartment for sheet-like recording media can, however, also be an output compartment in which printed recording media, arranged in a stack, are placed one after the other. It may be the case that the stack surface has to be continuously adapted to the position of the transport path in the output station in order to ensure proper storage of the recording media. However, it may also be the case that the incoming recording media are aligned in an oem stacking compartment by feed devices which are in frictional contact with the stacking surface. In this case, too, continuous level control of the stack of recording streams is required. Since such applications are by no means unusual, a number of solutions for level control of a recording medium stack have also been known to the person skilled in the art for a long time.
- 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 design 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 relatively frequently used in order to vertically adjust the stacking compartment in the desired manner.
- stacking compartment 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 stackers.
- the invention is therefore based on the object of providing a stacking compartment for sheet-like recording media of the type mentioned at the outset which, despite a high load to be absorbed, is securely guided in the form of an extensive stack of recording media during its vertical movement and can be produced inexpensively.
- this object is achieved according to the invention with the features described in the characterizing part of the main claim.
- the solution according to the invention first of all provides that guide rails are used as frame parts which are favorable in relation to the ratio of their mass to the rigidity. If one forms such guide rails, as is preferably aimed for, as extruded profiles, there are possibilities of cross-sectional design which allow a particularly high rigidity with low weight. Nevertheless, inexpensive solutions can be achieved due to the manufacturing process.
- the height-adjustable part of a stacking compartment designed according to the invention is formed from the end wall and laterally from the longitudinal side of the projecting shelf supports. Only the end wall can be displaced vertically on its narrow sides in the guide rails and is preferably fixed twice in each case with a sufficient vertical distance in order to absorb the high torque of the stack of recording media supported on one side. Finally, the form-fitting guide for the vertical adjustment of the end wall forms a chain axially inserted in the guide rails and braced there in connection with a driven pinion.
- FIG. 1 shows a schematic illustration of a stacking compartment designed according to the invention in a three-dimensional exploded view, which for reasons of clarity shows only the most important design features
- FIG. 2 shows a detailed view of one of the guide rails serving as a frame for the stacking compartment, from which it can be seen how a chain, on which the end wall of the stacking compartment itself pulls up, is arranged and
- FIG 3 shows, in a further view, in addition to a cross section through one of the guide rails, the schematically illustrated drive for the vertical movement of the stacking compartment.
- a stacking compartment for sheet-like recording medium 1 is shown in an exploded view. It is therefore also not shown whether this stacking tray should be used as an input or output tray 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 in order, for example, to reach a certain level of the stacking surface of the sheet-like form gene to keep record carrier 1 constant, although the stack height is constantly changing.
- an end wall 2 of the stacking compartment forms, together with compartment supports 3, which are rigidly projecting vertically on one of its side walls, the height-adjustable part of the stacking compartment.
- compartment supports 3 which are rigidly projecting vertically on one of its side walls, the height-adjustable part of the stacking compartment.
- guide rails 4 are provided, which are made as extruded profiles. This manufacturing process enables a liberal design of the cross-sectional shape, which is optimized here to achieve high rigidity with the lowest possible weight.
- Each of these guide rails 4 thus has a base 5 of essentially rectangular cross section.
- a supporting body 6 with an approximately trapezoidal cross-section sits on this base.
- In this support body 6 are two, in the direction of
- the first guide groove 7 has a rectangular cross section and opens toward the side of the guide rail 4 facing away from the base 5.
- the second guide groove 8 is arranged in the support body 6 rotated by 90 °, it opens in a direction parallel to the base 5 the guide rails 4 lies.
- 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.
- 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, although the attached to the end wall 2 and the stack of recording media carrying tray 3 exert a corresponding torque on these ball bearings 11.
- FIG 1 also indicates that a chain 12 is inserted into the second guide groove 8 of the guide rails 4.
- the cross-sectional shape of the second guide groove 8 is adapted to this chain cross-section and the overall function of the guide rails with the proviso that all possibilities are used to make the guide rail 4 torsion-resistant by designing its cross-sectional shape.
- FIG. 2 shows a partial section through one of the guide rails 4 in order to further illustrate the arrangement of the chain 12 in the second guide groove 8.
- the chain 12 is inserted into the second guide groove 8. It is fixed at the upper end of the guide rail 4 with an axis 13 which is inserted into the vertically projecting fastening eyes 14 of the guide rail 4.
- the chain is clamped by means of a tension spring 15. It is thus arranged in the guide groove 8 in a stationary manner under prestress.
- This chain forms an element of the gear unit with which the stacking compartment is adjusted in height.
- FIG 3 shows further elements of this gear arrangement.
- a sprocket 16 is in engagement with the chain 12. This sprocket 16 is coupled to a sprocket 17. This is shown in FIG 3 in cooperation with another
- Chain 18 shown which in turn is driven by a differential motor 20 via a further sprocket 19.
- In 3 shows schematically only one side of the mounting of the end wall 2. The opposite side is, however, mirror-symmetrical, apart from the fact that the compensating motor 20 is of course only provided once.
- the sprocket 17 is rigidly arranged together with the pinion 16 on a lifting shaft 21 which rotates in the end wall 2 and whose right end, shown in FIG. 3, forms one of the first bearing journals 9.
- a pinion 16 is rigidly arranged on this shaft, which is in operative connection with a further chain 12 clamped in the opposite guide rail 4.
- the compensating motor is - for reasons of clarity in the schematic representation of FIG 3 not shown - mechanically connected to the height-adjustable part of the stacking compartment, preferably fixed on the carriage 2. It is designed as a clocked gear motor that inhibits itself. This ensures the current vertical position of the stacking compartment.
- a sensor 22 is provided assigned to the surface of the stack of 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 fed to the compensating motor 20 as a control clock signal for an opposite compensating movement.

Abstract
Un compartiment pour piles de feuilles d'impression dans une imprimante est ajustable en hauteur, ce qui permet d'ajuster le niveau de la surface de la pile de feuilles. Une solution économique est recherchée pour assurer un guidage sûr du mouvement vertical malgré des charges importantes. Le cadre fixe du compartiment est formé de rails de guidage (4) situés à ras d'une paroi frontale (2) du compartiment. La paroi frontale (2) du compartiment forme un chariot auquel sont assujettis des supports (3) qui font latéralement saillie. Le chariot (2) est guidé dans les deux rails de guidage (4) de manière à résister aux torsions. Afin d'ajuster le chariot (2) en hauteur, une transmission par chaîne (12, 16 à 21) comprend une chaîne (12) fixée dans chaque rail de guidage (4). On peut utiliser ce compartiment pour feuilles dans des imprimantes comme compartiment d'introduction ou de sortie feuille à feuille.A compartment for stacks of print sheets in a printer is adjustable in height, allowing the level of the stack of sheets to be adjusted. An economical solution is sought to ensure safe guiding of the vertical movement despite heavy loads. The fixed frame of the compartment is formed of guide rails (4) located flush with a front wall (2) of the compartment. The front wall (2) of the compartment forms a carriage to which supports (3) are attached which protrude laterally. The carriage (2) is guided in the two guide rails (4) so as to resist torsion. In order to adjust the carriage (2) in height, a chain transmission (12, 16 to 21) comprises a chain (12) fixed in each guide rail (4). This sheet compartment can be used in printers as a sheet feed or output tray.
