Definitions

  • the invention relates to a method for feeding sheet sheets of different rectangular formats, which are output by a printer or copier at a first speed onto a feed table and then fed to a folding machine, sensor means for determining the sheet format being present and selectively at least one predetermined one Sheet format is rotated by 90 ° relative to the table level.
  • the invention relates to a device, in particular for performing the method.
  • Electrostatic printers are known for producing large-format drawings. Printing takes place from paper rolls, whereby two or more paper rolls of different widths can be present. The drawings are printed either lengthways or transversely to the longitudinal direction of the web. Such large-format drawings can be folded immediately after printing by folding machines known per se. The folding process must take place in such a way that after folding the head or the parts list always lies on the top sheet, i.e. the cover sheet. The folding machine can be programmed so that a different number of folds can be carried out depending on the sheet length.
  • CH-PS 650 221 a device for transporting rectangular sheets is known, or the like from a copier. are output and turned through 90 ° so that they can be fed to a downstream processing device in the correct position.
  • the turning process takes place in such a way that a stationary needle-like holding member is eccentrically inserted into the sheet arch along the transport path and the linear moving transport members located to the side of this holding member cause a pivoting movement of the sheet arch by 90 °.
  • Disadvantages are the slow transport and the large space requirement of the feed table in the longitudinal and transverse directions, including transverse transport elements for the sheet sheets.
  • the object is to be achieved by a printer or the like. Continuously output large-format sheets, which are incurred indiscriminately in the longitudinal and landscape format, with the avoidance of manual work, depending on the format, to feed a folding machine in the correct position with a small footprint of the feed table between the printer and the folding machine.
  • sheet sheets can be fed continuously to the feed table without the turning process being disrupted in the case of predetermined sheet sheet formats.
  • the different sheet formats fed in random order are recognized on the feed table and only those are selected which require a 90 ° rotation in order to be fed to the folding machine in the correct position. Under fit is understood that after the folding process the head or the parts list always lies on the cover sheet, preferably at the foot, in a readable position.
  • printers and copiers on the market for the production of large-scale drawings from a roll.
  • “Printers” are to be understood in particular to mean electrostatic printers and other photographic production processes.
  • the printer or the like can work from two or more paper supply rolls of different widths.
  • the printed drawings of standardized rectangular size continuously arrive on a feed table 2, to which a folding machine 9 is connected.
  • These sheets 3, for example in the form of large-area machine or construction drawings, are each provided with an inscription head 11, 12 or a parts list, which should be on the top of the cover sheet after folding. Since the folding program of the folding machine is given, this presupposes that the drawings with their labeling head 11, 12 or parts list are to be inserted into the folding machine in a predetermined position. Since the printed drawings can be in either longitudinal or landscape format, one format must be rotated by 90 ° on the feed table.
  • Fig. 1 the output of a drawing in standard format A1 (592 x 841 mm) corresponding to the paper roll width is shown as an example, in which the longitudinally extending parts list 11 is located on the upper left edge.
  • the printer can also output a drawing in standard format A2 (420 x 594 mm), in which the parts list 12 comes to lie transversely to the lower edge of the sheet.
  • the A2 format corresponds to half of the A1 format.
  • the position of the parts list 12 differs from the position of the parts list 11 of the format A1, as is shown in full lines in FIG. 1.
  • the printer or the like can output sheets from a second, narrower supply roll, for example A3 (297 x 420 mm), the A4 format also having to be turned over.
  • a second, narrower supply roll for example A3 (297 x 420 mm)
  • the A4 format also having to be turned over.
  • these sheet standard sizes A3 and A4 were not shown in FIG. 1; however, the turning principle is the same.
  • the sheet sheets 3 output by the printer 1 or the like and reaching the feed table 2 are scanned by sensors 5-8 to determine their format.
  • the scanning is carried out by three sensors 5, 6, 7, which are arranged one behind the other in the sheet feed direction Z in the table center area and to which a fourth sensor 8 is laterally assigned.
  • the selection circuit recognizes this sheet size A2.
  • the sensor 7 covers the sheet sheet A2 and at the same time releases the sensor 5, a rotary movement of this sheet sheet 3 is initiated.
  • the rotary movement is clockwise according to arrow U through an angle of 90 ° around the center of the blade P.
  • the sensors 4-8 are preferably light barriers; however, microswitches or the like could also be used.
  • the sensors are preferably reflection light sensors which are embedded in the feed table flush with the table surface. It is also possible to temporarily stop the transport members 10 during the rotary movement.
  • FIG. 3 shows the design of the feed table 2.
  • the table surface is penetrated from below by a plurality of transport rollers 10, 17, which are driven by two drive motors 13, 19 via toothed belts 14 and are controlled by the electrical control 33.
  • Above these transport rollers 10 are in four support rails attached to the cross member 24 in loose support metal balls 16 which, by their own weight, press an intermediate sheet against the transport rollers 10 and thereby bring about the sheet feed.
  • the transport rollers 17 located on the right in FIG. 3 are driven at a higher speed than the inlet-side transport rollers 10, so that the sheet sheets 3 are transported towards the folding machine 9 at a higher speed.
  • the folding machine 9 operates at a higher speed than the output speed of the printer 1 corresponds.
  • the transport rollers 10 are each provided with a conventional overrunning freewheel, which has the effect that a sheet caught by the faster-running transport rollers 17 is not inhibited by the slower-driven transport rollers 10.
  • the different speeds of the transport rollers 10 and 17 could also be achieved by a single motor 13 by means of different transmission ratios instead of by two different drive motors 13, 19, this being done by a transmission gear 27 with clutch.
  • the drive movement can be taken directly from drive elements 37 (FIG. 2) of the printer 1.
  • the 4 is designed to carry out a rotary movement of the sheet sheet 3 in the A2 format by 90 °. It contains a turntable 20 arranged flush with the table surface, above which there is a rotatably mounted counter pressure plate 22 at a distance.
  • the counter-pressure plate 22 is fastened to a yoke 24 which extends across the feed table 2 and on which four holders 21 also hang.
  • the lifting movement of the turntable 20 is carried out by a solenoid-type electromagnet 26, the central, vertical plunger 28 of which is connected to a rotatable shaft 30 via a roller bearing housing 32.
  • the electromagnet 26 is rigidly connected to the feed table 2 via a U-shaped holding plate 34 and a bearing body 36.
  • the shaft 30 is rotatably supported in a ball bearing 38 at the bottom and in a slide bearing 40 at the top and is axially movable.
  • a cross bolt 42 which is non-rotatably connected to the turntable 20, penetrates a longitudinal slot 44 of the shaft 30.
  • This hub 46 is rigidly connected to a drive wheel 48.
  • a toothed belt 50 is around this drive wheel 48 and wrapped around a pinion 49 of a stepper motor 54.
  • the stepper motor 54 is rigidly connected to the bearing body 36. The electrical control of this stepper motor 54 takes place via a control circuit 25.
  • the axis 30 and the turntable 20 rigidly connected to it can execute both an axial movement and a rotary movement.
  • a spring 23 causes the shaft 30 to retract into the rest position.
  • the feed table 2 presses against a stop 57 and can be pivoted up about a horizontal pivot axis 56. As a result, the entire feed table 2 can be pivoted upwards in accordance with arrow 55 in order to provide good accessibility between the printer 1 and the folding machine 9.
  • the mode of action is as follows:
  • a sheet 3 When a sheet 3 is fed to the feed table 2 from a printer 1 or the like at a first speed, namely the printer output speed, its format can be determined by the sensors 5-8 by evaluating the covered and free sensors. It is assumed that a sheet of sheet 3 with the format A2 is to be turned through 90 ° in order to be inserted in the correct position into the folding machine 9 which directly adjoins the feed table 2.
  • a suitable folding machine is shown in U.S. Patent No. 5,045,039.
  • the format selection circuit 15 causes the electrical control element 29 of the lifting and rotating assembly 18 to be activated, so that the sheet is raised in its middle section and between the turntable 20 and the counter-pressure plate 22 is clamped.
  • the cutting motor 54 starts and causes a rotation of 90 ° in a plane parallel to the table level.
  • the control member 29 causes the turntable 20 to be lowered again, whereupon the sheet 2 is gripped by the conveyor rollers 17. These are driven by the motor 13 at a second speed which is about three times higher than the running-in speed and which preferably corresponds to the working speed of the folding machine 9.
  • the drive rollers 17 could be driven by drive members of the folding machine instead of a motor 13.
  • the motor 13 is controlled by a control member 33. This increased take-off speed prevents faults with continuously new sheet sheets 3.
  • the turntable 20 does not need to be turned back, since the stepper motor 54 again executes a predetermined rotary movement by the stepper motor controller 25 during the next stroke movement.
  • One embodiment variant is that even abnormally long formats can be fed directly to the folding machine 9, e.g. long electrical schematics.
  • the control device is modified in such a way that when all sensors 4-7 are covered, the electric motor 13 and the folding machine 9 are lowered in the sheet transport speed and converted to the transport speed of the printer 1. This prevents the sheet that has not yet left the printer from being drawn into the folding machine which operates at a higher folding speed. As soon as the rear sheet edge has released the sensor 4 or, if need be, an even further sensor on the printer side, the sheet transport and folding machine speed can be increased again.
