Definitions

  • the invention relates to an arrangement for the mechanical coupling of structural units, such as. B. a printing unit of an electrophotographic printer or a copier with other units in an axis-parallel orientation with respect to the transport path of a continuous recording medium.
  • a continuously revolving photoconductor drum is generally provided as an intermediate carrier for print information, which is initially charged evenly in its circulation in order to generate a latent charge image.
  • the uniform charge is optically discharged point by point, depending on the pressure information, and a charge distribution corresponding to the pressure information is thus generated on the intermediate carrier.
  • this charge image is colored by a toner mixture, then the toner particles are transferred to a recording medium and chemically or thermally fixed there.
  • the transfer of the toner particles onto the recording medium the so-called printing, the further transport of the recording medium with the toner image which has not yet been wiped over, and the fixing process.
  • the quality of the print result is decisively influenced.
  • the recording medium in the transfer printing station be exactly parallel to the axis and without relative speed with respect to the intermediate carrier, ie the photoconductor drum is moved, otherwise the printed image is already blurred here.
  • the fixing process is similarly critical, in particular when the fixing of the toner image on the recording medium is carried out by means of the thermal printing method.
  • the recording medium runs between a pair of rollers, the so-called fixing roller or the pressure roller.
  • the heated fixing roller which faces the image side of the recording medium, emits a sufficient amount of heat to the recording medium in order to plasticize the toner particles in combination with the pressure exerted by the pressure roller and melt them onto the surface of the recording medium.
  • the said pair of rollers of the fusing station is set exactly axially parallel to the transport path of the recording medium, otherwise not only mechanical crushing of the conveyed recording medium arises but also errors in the fixing, which lead to a reduction in the print quality.
  • electrophotographic printing or copying machines are accordingly complicated and time-consuming.
  • electrophotographic printing or copying devices are therefore constructed in a modular manner from individual structural units, with the corresponding tolerance limits being observed within a module, so that it is then relatively easy to replace, apart from a secondary condition, namely that, after such an exchange, the required axis-parallel assignment to the corresponding part of the transport path of the record carrier must again be established.
  • the first assembly when assembling the individual structural units to form a printing or copying machine therefore usually requires a series of manual and time-consuming measures, especially in order to align all the individual structural units exactly parallel to one another. The same applies if inspection or maintenance work has to be carried out.
  • the object of the present invention is to develop an arrangement of the type mentioned in such a way that with simple means during an initial assembly, but also when an exchange of individual structural units, an axis parallel is readily achieved Allocation of the individual units to one another can be realized without the need for complicated and time-consuming adjustment processes.
  • the solution according to the invention is based on the fact that the electrophotographic process already specifies a printing unit as the core of such a printing or copying device, in the center of which the intermediate carrier, i. H. the photoconductor drum is arranged.
  • a plurality of individual assemblies are already arranged around the photoconductor drum, which must be assigned to them precisely in order to be able to generate a correct, colored charge image corresponding to the printing information. It therefore makes sense to design this core piece of an electrophotographic printing or copying device as a structural unit.
  • this printing unit can be expedient to construct this printing unit as an integrated basic unit in connection with the devices which bring the recording medium to and from this printing unit and remove it again.
  • a support is provided for these components which are not integrated into the basic unit and which has corresponding receptacles for the components to be attached, so that these components are already exactly aligned with respect to the carrier by simple hanging. Then the problem arises of firstly aligning this carrier, in turn, parallel to the axis of the basic unit mentioned. This is achieved here by means of a crossbeam which is connected on the one hand to the basic unit in two articulation points and on the other hand to the support in a further two articulation points.
  • the base unit is fixed on a frame or frame of the printing or copying machine, then after the carrier has been coupled to the base unit via the cross member, it is only necessary to align it with respect to the frame in one direction, in particular the vertical, with the axis parallelism of the carrier is inevitably obtained with the basic unit and thus the structural units to be fixed on the carrier are in turn assigned to the basic unit in each case parallel to the axis without further adjustment measures.
  • the individual structural units attached to the carrier are interchangeable, provided the suspension points of the structural units on the carrier are tolerated closely enough.
  • their axis parallelism to the printing unit is particularly critical.
  • the fixing station if the thermal printing process is used for fixing, is also subject to thermal expansions during operation and therefore corresponding degrees of freedom for thermal expansions must be provided without the axis parallelism being lost.
  • the fixing station for operation is thus articulated in both the axial and vertical directions with two degrees of freedom with respect to the rigid support, but is nevertheless easily replaceable as an individual structural unit.
  • the electrophotographic printer shown schematically in FIG. 1 has a supply table 10 for receiving a supply stack 11 made of pre-folded continuous paper 12.
  • the record carrier 12 is fed to the actual electrophotographic printing unit 15 via a paper dividing device 13 and a pivotable actuating rocker 14 provided with paper guide elements.
  • This has a transfer station 17 which can be swiveled in and out of a photoconductor drum 16 and further devices which are arranged around the photoconductor drum and are required for the electrophotographic process.
  • the photoconductor drum for generating a toner image on the recording medium 11 is charged by a charging device 18 and discharged as a function of the print information via an LED character generator 19.
  • the charge image generated is colored in a developer station 20 with a developer mixture of toner and carrier particles and transferred to the recording medium 12 in the transfer printing station 17.
  • the photoconductor drum 16 is unloaded via an unloading station 21 and cleaned in a cleaning station 22, so that it can be recharged via the charging device 18.
  • the recording medium 12 which is now carrying the toner image, is fed to a fixing station 23 for the wipe-proof fixing of the toner image and then placed on a deposit table 24.
  • the printer is coupled, for example, to other printing devices in order to, for. B.
  • the web-shaped recording medium 12 can also be fed directly to the paper dividing device 13 via external paper feed channels 25.
  • a supply stack 26 which is not integrated in the printer as a supply stack; further paper feed elements 27 may be necessary.
  • Figure 1 illustrates even in the schematic structure that it is expedient to design at least the photoconductor drum 16 and the units 17 to 22 arranged around it as a common structural unit. Furthermore, all essential elements for guiding the recording medium 12, at least those in the area of the electrophotographic printing unit 15, are also to be understood as one structural unit. In this embodiment it is assumed that the elements for paper transport z. B. 13, 14 and 27 together with the electrophotographic printing unit 15 form a mechanically rigidly coupled unit, which is referred to below as the basic unit. As FIG. 1 shows, the fixing station 23 and in particular also the paper stacking devices, in particular the storage table 24, are spatially separated therefrom. There is therefore the problem of assigning these spatially separate structural units, such as the storage table 24 with its stacking devices and the fixing station 23, to the basic unit 28 parallel to the axis.
  • FIGS. 2 and 3 now show in a top and side view in detail the means by which this axis-parallel assignment is achieved without having to first set this parallelism during assembly by means of complicated adjustment measures.
  • all details which are not absolutely necessary are omitted from the illustration in FIGS. 2 and 3, so that a corresponding clarity of the illustration is achieved.
  • the base unit 28 has two bearing eyes 29, which are aligned parallel to one another as required.
  • a cross member 30 is hooked into these bearing eyes 29 via connecting pins 31.
  • This cross member 30 consists of two cross member elements 301 and 302, for example, which are designed as two cast rails and have no rigid connection with one another.
  • Another coupling element is a carrier 32, the basic shape of which is U-shaped, i. H. on a base part 321 there are two side parts 322 at a distance from one another and facing one another.
  • the side parts 322 of the carrier 32 have arms 323 which are rigidly coupled to them and protrude laterally upwards, each with a further bearing eye 324, into which one of the ends of the cross member elements 301 and 302, respectively, of the basic unit 28.
  • the carrier 32 is connected via three support points 325 and 326 via its base part 321 to a framework 1 of the printer, which is only shown schematically.
  • the carrier 32 is aligned exactly vertically to the printer frame 1 via these three support points 325 and 326. This is indicated schematically by a spirit level 34.
  • the alignment is carried out in such a way that the support points 325 and 326 are underlaid accordingly in order to set the exact verticality of the support 32.
  • the carrier 32 is aligned exactly vertically, it stands at the same time also, due to the connecting traverse 30 parallel to the axis of the base unit 28, as indicated in FIG. 2 by a parallelism symbol in the connecting line of the attachment points A1, B1 or A2, B2 of the traverse elements 301 and 302.
  • the storage table 24 shown in FIG. 1 actually contains an entire stacking device. It is readily conceivable that this stacking table 24 must perform a vertical lifting or lowering movement during operation, which is dependent on the stack height of the stored recording medium 11 which is being formed.
  • the vertical guide for the stacking table 24 is arranged in the side parts 322 of the carrier 32.
  • a running profile 327 is schematically indicated in FIG. 3, in which the work table 24 is guided over rollers 241.
  • a crawler chain 35 is also shown schematically, which runs via a drive pinion 36.
  • the crawler chain 35 is fixed on one side in a side part 322 of the carrier 32 and is connected at its other end to the stacking table 24. Depending on the direction of rotation of the drive pinion 36 driven by a motor, the stacking table 24 is then raised up or lowered down.
  • the running profiles 327 are inserted into a receptacle of the side parts 322 of the carrier 32, which is shown schematically in FIG. 3, as indicated in point D of FIG. 3.
  • these side parts accommodate the drive unit described for the upper part of the work table.
  • the work table 24 with its integrated rollers 241, which is suspended in the side parts 322 of the carrier 32, is thus assigned to the other structural units of the printer parallel to the axis.
  • the fixing station 23 is connected via two further connecting pins 37 in points C1 and C2, respectively, in the side parts 322 of the carrier 32.
  • FIG. 2 illustrates that it is brought into contact at a point G with respect to one of the side parts 322 of the carrier 32.
  • FIG. 3 illustrates that the fixing station 23 is supported as a support point at a point F fixed to the housing.
  • This support point F and the contact point G form the two fixed points for the arrangement of the fixing station 23 rotatably arranged in the attachment points C1, C2. It is thus coupled in parallel to the other structural units of the printer in such a way that the fixing station 23 in the longitudinal expansion caused by heat specified directions v and w, ie the corresponding degrees of freedom remain in the axial direction and perpendicular to it.
  • This coupling of the fixing station 23 is particularly important because, in addition to the possibility of length expansion, this also creates the prerequisite that the fixing station 23 can be replaced as an independent structural unit at any time without special adjustment processes simply by hanging it in the carrier 32.
