Definitions

  • the present invention relates to delivery devices in the folder of a rotary printing press.
  • a folder delivery in multi-flow production is known from the prior art (DE-PS 38 17 804).
  • a plurality of bucket wheel sections which can be operated in parallel and which connect to one another laterally are driven independently of one another.
  • At least one guide disk is provided between the impeller sections.
  • the outer side disks on both sides of the paddle wheel sections can be moved in the axial direction via a toothed rack on a shaft.
  • the guide disks arranged at the connection points of the two shaft ends can be moved a small distance in the axial direction via adjusting spindles.
  • Conveyor belts rotating on rollers that pass through a vibrating device can be moved in the axial direction using scissors that have at least one joint.
  • the invention has for its object to improve the folded product delivery in the folder of a rotary printing press to the effect that a simultaneous adaptation of the folded product delivery devices to the folded product format takes place during operation of the folder. Due to the fact that the product flow can be preset, automation of the folder can be achieved, thus saving setup time.
  • the object is achieved in that delivery devices in the folder of a rotary printing press are suitable for single and multi-stream production, that they can be operated in parallel, that they can be driven independently of each other, that they can be adjusted automatically or manually during the operation of the folder, that these can be moved simultaneously by adjusting units, and that during the adjustment the distance of the delivery devices from one another can be set as desired between a minimum and a maximum adjusting position.
  • the advantage of the present invention is that it is now possible to automatically adjust the former together with the paddle wheel extensions. This saves set-up time and in particular reduces the time required to adapt the delivery devices to new formats to a minimum. A drastic reduction in makeready times can thus be achieved in a folder with four paddle wheels.
  • the automatic format adjustment also enables the side folding product guides in the initial phase of printing while the delivery of the sheets is still irregular Folded copies can be parked to avoid paper jams in the folder. The operator can therefore devote himself to other monitoring activities during the start-up phase.
  • a favorable embodiment of the invention provides paddle wheel disks, transport and delivery belts, the paddle wheel disks being slidably mounted on a shaft and being moved by arms which are fastened to sliding pieces.
  • the advantage of this version is the separate displacement of each individual paddlewheel disc with automatic format adjustment during operation.
  • an advantageous embodiment of the subject matter of the invention provides that bearings are attached to the paddle wheel disks and rings are mounted thereon on which the arms are attached.
  • the advantage of this design is that the weight of the arms lies on the rings and this prevents the bucket wheel disks from tilting when moving on the shaft thanks to the bearings. There is therefore no wear between the moving parts.
  • the exact mounting of the arms on the paddlewheel disks also enables precise guidance of the paddlewheel disks on the shaft.
  • bushings and adjustment spindles are mounted in the side walls of the folder and are driven simultaneously by an electric motor.
  • the advantage of this embodiment is that, for example, four movable paddlewheel disks can be moved by one adjustment unit. A synchronous adjustment of the delivery devices is thereby achieved.
  • Another cheap embodiment of the invention comprises a shaft with sliders slidable thereon; Spindle heads that move the sliders; Adjustment spindles, on which sleeves are fastened in the area of the spindle heads, which have alternating single or multiple thread sections; or threads with different thread pitches are milled into the adjustment spindles. It is advantageous that the choice of threads determines a certain proportional travel of the paddlewheel disks and the same distance to be maintained between the individual paddlewheel disks during the adjustment process.
  • a further advantageous embodiment of the invention provides that slidable stops are fastened on these axes for the sliding pieces which can be moved on axes.
  • the advantage here is a limitation of the travel range with simple means.
  • An alternative embodiment of the invention comprises a tubular shaft on which displaceably arranged paddle wheel disks are attached; spindle heads connected to the impeller disks; adjusting spindles mounted in the tubular shaft and interacting with the spindle heads; an electric motor mounted in the tubular shaft, and a pinion and gearwheels via which the electric motor moves the adjusting spindles.
  • a side folding product guide is provided, an arm connected to the side folding product guide, a slide piece connected to the arm and a device for pneumatically activating the slide piece or an adjusting spindle connected to the slide piece, and a handwheel connected to the adjusting spindle for manual activation of the slider.
  • a further advantageous embodiment of the invention provides that conveyor belts which are guided into the spaces between the paddlewheel disks are simultaneously automatically adjusted when the paddlewheel disks are adapted to the format.
  • the adjustment units for the paddle wheel disks and the lateral folding product guide are designed in a modular design.
  • the advantage of this design is the space-saving arrangement of the adjustment units, the quick interchangeability and the cost-effective production of the same.
  • scraper tongues are provided on arms which move the paddlewheel disks. These ensure a continuous fold product sequence on downstream conveyor belts.
  • FIG. 1 shows a side view of a paddle wheel disc with conveyor belts and adjustment units for lateral folding product guidance and the paddle wheel discs in modular construction.
  • the delivery devices 3 comprise belts 2 which run on belt rolls 1.
  • the bands 2 lead folded copies to the paddle wheel disks 6, which are arranged side by side on the shaft 4.
  • the paddle wheel disks 6 are designed such that they form pockets 7, into which 2 folded products are conveyed by the belts.
  • a respective arm 8 is connected to a respective paddle wheel disk 6.
  • adjustment units 5 and 9 are arranged one above the other in a modular design.
  • the adjustment unit 10 can be seen, by means of which the lateral fold product guide 11 can be automatically positioned.
  • Scraper tongues 36 are provided on the paddle wheel disks 6, which can be screwed onto the arms 8.
  • FIG. 2 shows the top view of paddle wheel disks in the smallest product format and with the folded product guide 11 on the side.
  • Shaft 4 has four adjustable paddle wheel disks 6, which are connected to sliders 12 via arms 8.
  • the sliders 12 are arranged on an axis 13 and slidable in both directions on this.
  • stops 14 are used, which are detachably fastened on the axis 13.
  • the sliders 12 have spindle heads 14a, in which adjusting spindles 15 can rotate.
  • the adjusting spindles 15 are connected at their ends to bushings 16 which are mounted in the side walls 17 and the middle wall 18.
  • An electric motor 19 actuates the adjusting spindles 15 via a gear consisting of a worm 20 and a worm wheel 21.
  • the adjusting spindles 15 have threaded sections 23, 24, 25 and 26. These threaded sections are of different lengths or have different thread pitches, depending on the paddle wheel disc 6 to be moved.
  • the threads can be milled into the adjusting spindles 15 or be designed as single or multiple threads.
  • the synchronous adjustment of the bucket wheel disks 6, while maintaining a uniform distance between the bucket wheel disks 6, is achieved by different thread designs.
  • the paddle wheel disk 6, designated "wheel 5" is the longest way back when it is adjusted from the minimum to the maximum position. This is achieved by the threaded section 26 (carried out with a large pitch).
  • the movable paddle wheel disk 6, designated "wheel 4" covers the third longest path during the adjustment.
  • the threaded section 25 is somewhat shorter than the threaded section 26.
  • a thread with a somewhat flatter pitch can be used.
  • a paddle wheel disk 6a is mounted on the shaft 4 in a stationary manner. If the adjustment spindles 15 are driven by the electric motor 19, a format adjustment is achieved by their simultaneous drive and the adjustment path predetermined by the length of the threaded sections 23, 24, 25 and 26. A readjustment is not necessary because the positioning positions are reached with great accuracy.
  • threads with different number of gears can also be used, whereby the required movement of the paddle wheel disks can also be achieved.
  • the simultaneous automatic adjustment of the bucket wheel disks, together with the automatic adjustment of the former, allows extremely short set-up and changeover times while the machine is running.
  • FIG. 2 also shows an adjustment unit 10 with which the lateral folded product guide 11 can be turned on and off.
  • a pneumatic cylinder 29 can be provided in the slider 27, with which a pneumatic shutdown of the folded product guide is possible when the printing machine starts up.
  • the folding product guidance can be activated manually by means of a handwheel 30, which moves a fine adjustment spindle 31.
  • the adjustment unit 10 is designed in a modular design for the adjustment of the side fold product guide 11 and can thus be used for the operator and for the drive side.
  • the folded product guide opposite the movable folded product guide 11 is marked "wheel 5" connected and is moved together with this when adjusting the paddle wheel disk 6.
  • FIG. 3 shows a top view of the paddlewheel disks set to the largest format with the folded product guide on the side.
  • the paddle wheel disks 6 are moved to their maximum position on the shaft 4, which is mounted in bearings 32, 33.
  • the side folding product guide 11 is employed on the "wheel 1".
  • the sliding pieces 12 are moved into the respective setting position by the spindle heads 14a.
  • the adjustment path which the slide 12 has covered can be recognized from the position which the spindle head 14a has assumed on the threaded section 26.
  • the arms 8 are supported on the paddle wheel disks 6 via bearings 34 on rings 35.
  • Scraper tongues 36 are also provided on the arms 8, which guide the folded products out of the pockets 7.
  • a drive wheel 37 is arranged on the shaft 4 next to the bearing 32, with which the shaft 4 can be driven via a belt drive.
  • Fig. 1 tapes 2 are shown, the guide rollers 1 are brought up to the circumference of the paddle wheel 6. These belts 2 can be fed into the spaces between the individual paddle wheel disks 6 both on the folded product supply side and on the output side. With the automatic format adjustment, these conveyor belts can be moved in accordance with the displaceable paddle wheel disks 6 in order to achieve an optimal product delivery.
  • FIG. 4 shows an embodiment of the subject matter of the invention, in which a cantilevered shaft 38 mounted in a central wall 17 of the folder is shown with a plurality of paddle wheel sliding pieces.
  • the self-supporting Shaft 38 is supported in shaft bearing 39.
  • An abutment housing 40 is flanged to the middle wall 17, in which one end of the self-supporting shaft 38 is supported via an abutment 41.
  • a shaft key 42 is provided on the self-supporting shaft 38, with which the rotation of the shaft 38 is transmitted to an axially displaceable sliding sleeve 43.
  • a paddle wheel disk 6 is attached to the sliding sleeve 43.
  • the sliding sleeve 43 is connected to a push rod 45 via a rotatably mounted arm 44.
  • the push rod 45 is movable in the middle wall 17 by a bearing 46.
  • a push rod drive 47 serves to move the push rod 45 in the axial direction.
  • a key 48 is fastened on the sliding sleeve 43, by means of which the rotation of the self-supporting shaft 38 is transmitted to a sliding sleeve 49 via the sliding sleeve 43.
  • the sliding sleeve 49 is moved axially via an arm 50 and a push rod 51 in the same way as the sliding sleeve 43.
  • the push rod drive for the sliding sleeve 49 is not shown.
  • the sliding sleeve 49 itself has a feather key 52 which sets the sliding sleeve 53 in rotation and thus moves the paddle wheel disk 6.
  • the sliding sleeve 53 is moved in the same way as the two sliding sleeves described above via an arm 54 and a push rod 55.
  • Paddlewheel disks arranged next to one another can thus be adjusted by actuators in the middle wall of the folder.
  • Figure 5 shows a space-saving arrangement of the adjustment mechanism.
  • a tubular shaft 57 is received between the side wall 18 and the middle wall 17 and rotates in bearings 32 and 33.
  • An electric motor 19 is installed in the tubular shaft 57 and drives a first adjusting spindle 15 via a pinion 58 and a gear wheel 59.
  • Gear wheels 22 transmit the drive from the first to a second adjusting spindle 15, which is also mounted in the tubular shaft 57.
  • 15 threaded sections 23, 24, 25 and 26 are provided on the adjusting spindles, through which spindle heads 14b can move laterally and thus can move the paddle wheel disks 6.
  • Scraper tongues 36 are attached to the movable paddle wheel disks 6.
  • the paddle wheel disc 6a is fixed on the tubular shaft 57 and is not displaceable. Due to different thread pitches of the threaded sections 23, 24, 25 and 26, the paddle wheel disks 6 can be displaced proportionally sideways. Furthermore, the beginning of the respective threaded section can be placed on the drive spindles 15 in such a way that a proportional displacement corresponding to the path to be traveled by the respective paddle wheel disk 6 can take place.
  • the spindle heads 14b move in recesses of the tubular shaft 57 which run parallel to the axis of rotation and can be driven via a drive wheel 37.
  • the electric motor 19 is supplied with power via an electrical rotary contact 56. This embodiment enables space-saving accommodation of the adjustment mechanism in the shaft on which the paddle wheel disks are arranged. This results in a simpler adjustment of the scraper tongues and a more cost-effective construction.
