Definitions

  • the invention relates to a paper stacking device for prefolded continuous paper according to the preamble of claim 1.
  • Such a paper stacking device is known from EP-A-0 144 861. It has a table top that can be moved horizontally in guides and is moved back and forth by a crank mechanism with a stationary motor by a stroke that extends slightly beyond the form length of the fanfold paper.
  • the stacked paper rests on two support belts, which are clamped on one side on the stacker housing at both ends and are guided to the underside of the table via two deflection rollers mounted on an opening of the table.
  • the paper web is inserted and unrolled under the stack by the lifting movement of the table and the rolling movement of the support belts.
  • inclined bristles prevent the paper from slipping back as a backstop.
  • the object of the invention is to design a paper stacking device of the type mentioned at the outset in such a way that a simple changeover to other paper formats is possible and that the entire device takes up as little space as possible.
  • the paper stacking device is to be designed in such a way that integration into a high-performance printer is possible and a high level of operating comfort is possible.
  • the paper stacking device can be easily adapted to different paper formats and the whole The dimensions of the paper stacking device are so small that it can be integrated into the printer housing.
  • the paper stacking device can be designed so that it can be swung in and out of the printer housing.
  • the design of the support surface for the support belts in the form of coupled single elements enables the support surface to be designed with low mass, which considerably facilitates the back and forth movement of the feed area.
  • a known paper stacking device shown schematically in FIG. 1 consists of a table top 10 which is horizontally movable in guides and which is moved back and forth by an eccentric drive 11 by a stroke slightly exceeding the form length 12 of the prefolded continuous paper 13.
  • the stacked paper 14 lies on two support belts 15, which are clamped immovably at both ends on the stacker housing and are guided to the underside of the table via two deflection rollers 16 mounted at an opening of the table. After the first sheets have been manually inserted into the correct position, the paper web 13 is rolled under the stack 14 by the lifting movement of the table 10 and the rolling movement of the support belts from below.
  • the support straps 15 are guided on the underside of the table via further deflection rollers 17 and fastened to the stacker housing via spring elements 18.
  • inclined bristles 19 of a backstop prevent the paper from slipping back.
  • a blower 20 ensures the correct entry of the paper web 16 at the entrance of the feed area of the stacking device.
  • a stacking device constructed in this way requires a large space because of the size of the table top, including the lifting movement. If the form length is changed, the eccentric drive must be set separately.
  • the table top i.e. the storage surface for the support tapes 15 from a plurality of support elements 21 which are arranged on two, at the ends of the support elements arranged endless traction means 22 in the form of a toothed belt or chain pair.
  • the feed area 23 with the deflection rollers 16 fastened thereon.
  • two take-up rollers 24 are arranged below the feed area 23, which are also in engagement with the endless traction means 22 via gearwheels 25.
  • the paper stacking device can be driven by a stationary drive motor 26 which e.g. can be designed as an electronically controllable stepper motor which is reversible in its drive direction and which is likewise in engagement with the endless traction means 22.
  • the drive motor 26 - in accordance with the principle of FIG. 4 - is designed as an electronically controlled drive motor which is directly assigned to the feed area (23) and moves with it.
  • the drive motor 26 is controlled via an electronic device 27, which can consist of a conventional control device for stepper motors - with a device producing a rotating field, a counting device, etc. - and which contains an input device 28 for setting the form length.
  • This form length adjustment can e.g. take place automatically by scanning the stops 29 receiving the stack 14. Instead of the stops 29, automatically acting light barriers etc. can also be arranged.
  • High-performance printers for form printing also necessarily have information about the length of the form. Therefore, it would also be conceivable to set the form length directly via control signals that the printer control provides.
  • the rest position of the conveyor gap 30 and thus the position of the feed device 23 can also be specified electronically and the movement sequence can also be defined.
  • the feed device 23 with the paper web 13 fed therein is moved back and forth in accordance with the stacking process.
  • the support elements 21 support the support tapes 15, which are wound up and down in accordance with the back-and-forth movement on the winding rollers 24, wherein resilient elements corresponding to a spring roller blind can be provided in the winding rollers 24 for tightening the support tapes.
  • the two support bands 15 are attached to the two deflection rollers 16 and wound up.
  • spring elements (not shown here) could be provided in the rollers 16.
  • the different winding diameters which are dependent on the strip thickness and on the position of the deflection rollers, can be neglected, in particular in the case of thin and sufficiently elastic support strips 15.
  • the two deflection or take-up rollers 16 are stored in a slide movable in guides, as shown in FIG. 4, one of these deflection rollers 16/1 can be driven directly by a drive motor 26 and the second deflection roller 16/2 via a toothed belt 32.
  • the slide 31 with the two rollers 16/1 and 16/2 mounted therein moves to the right or to the left, one deflection roller winding up the support belt 15 and the other deflection roller releasing the support belt 15.
  • the drive motor 26 is moved with the carriage.
  • the drive motor can also be arranged in a stationary manner, as in the case of an exemplary embodiment corresponding to FIG. 5.
  • the slide 31 (guide area) contains, in addition to the two deflection rollers 16/1 and 16/2, a deflection wheel 33 via which the toothed belt driven by the motor, e.g. can also be a chain, is redirected.
  • the size of the stacking device can also be drastically reduced if the support elements 21 are not connected to deflection rollers 16 or winding rollers 16/1, 16/2 via joints (for example chain joints) as shown in FIG. 2, but rather on sliding guides 35, 6 and 7, arranged displaceably in one plane as shown in FIGS. 6 and 7 show an embodiment in which the support strips 15 are supported in the area between the winding rollers 16/1 and 16/2 and end plates 36 by five support elements 21. In this case, the distance between the five support elements is kept constant by scissor lattices 37.
  • the support elements are supported at the ends on sliding or contact surfaces 35. To reduce the friction between the support straps 15 loaded by the paper stack and the support elements 21, these support elements 21 can also be provided with rollers.
  • the relative movement between the support elements 21 and the support straps 15 loaded by the paper stack 14 can be largely avoided, as shown in the exemplary embodiment corresponding to FIGS. 8 and 9.
  • the support elements 21 are guided on contact surfaces 38, each support element having a free range of motion between a common end stop 39 on the end plate and a second individual end stop 40.
  • Each support element 21 is attached to the individual end stops 40 by individual ones Springs 41 (or compression springs) pushed as long as it is not in the way of the movement of the slide 31 with the winding rollers.
  • the sled 31 is within the range of motion of the support element 21, it rests on the sled 31 and moves with it. It is advantageous to store the winding rollers 16/1 and 16/2 higher according to the embodiment of FIG. 8, so that the support bands 15 are raised in the area of the slide 31.
  • the support elements 2 1 which are in contact with the slide 31 and move with the slide 31 are relieved of the bearing force of the paper stack 14, so that friction and wear are drastically reduced.
  • FIG. 10 A corresponding exemplary embodiment is shown in FIG. 10.
  • a stepped stop block made of soft magnetic material with a permanent magnet 43 underneath is attached to the slide 31.
  • Soft iron plates 45, which are assigned to the different stages of the magnetic stop block 42, are fastened to the support elements 21 as a contact surface. Due to the magnetic holding force, each individual support element 21 will follow the slide 31 until it arrives at the respective end stop.
  • a corresponding stacking device can be constructed with a low overall height and relatively small dimensions. This enables the stacking unit to be pivoted in a printer, e.g. to be attached to a laser printer. This can be used to automate the insertion of the continuous paper 13 between the rollers 16 of the stacking device, at least to simplify it significantly. It can also reduce the printer's dimensions for transportation.
  • the stacking device according to FIGS. 11 and 12 is pivotably arranged on the housing, the illustration in FIG. 11 showing the stacking device in the working position and FIG. 12 in the pivoted-in position.
