Definitions

  • the invention relates to a device for the lateral alignment of sheet material located on a conveyor according to the preamble of the independent patent claim, and a corresponding operating method for this device.
  • the alignment of the printed products is brought about by endless belts arranged on both sides of the conveyor and rotating in the conveying direction.
  • the distance between the opposing belts at the entrance of the device is greater than at its exit.
  • the device has a “funnel-shaped” opening.
  • the invention solves the problem of creating an alignment device in which the braking or frictional effect that occurs during the conveying process between the alignment device and the printed product is eliminated as much as possible and at the same time the alignment process essentially as a pure rotary movement of the Print products, without changing the distance between them.
  • the invention is based on the idea of arranging circulating belts on both sides along their entire length parallel to the shingled stream, driving these belts in such a way that their circulating speed essentially corresponds to the conveying speed and at the same time superimposing an oscillatory movement on the conveying direction that is oriented transversely to the conveying direction.
  • the main advantages of this invention can be seen in the fact that the printed products are aligned essentially by a pure rotary movement about their respective central vertical axis. In this way, a change in the distance between the printed products is avoided, as a result of which a high conveying speed can be maintained. In addition, congestion is largely excluded.
  • the invention allows the device to be designed in such a way that it can be used in a mobile manner on the scale stream where it is desired. This means that several alignment devices can also be used on a production line, for example wherever an intervention in the scale flow changes its (lateral) order.
  • constructive means are provided in order to change the distance between two opposite alignment units of the device for the purpose of adaptation to the respective width of a shingled stream.
  • the device according to the invention allows a relatively light construction of the movable components and the use of specifically light materials, so that the desired high conveying speed can be achieved despite the back and forth movement of the alignment units.
  • the endlessly circulating belts of the bilateral alignment units have serrations on their inner surface which engage with corresponding serrations on the circumference of the belt pulleys driving the belts.
  • the inner run of the circumferential belts facing the conveyor form a U-shaped channel with the conveyor - seen in cross section.
  • each pulley has an eccentrically arranged bore, which is used to receive a drive shaft and to receive a loosely rotatable shaft serves.
  • the two pulleys designed in the manner of an eccentric and arranged on an alignment unit have the same circumferences and are connected via the endless toothed belt in such a way that they are always at the same distance from the conveyor or the same together with the endless toothed belt during a full rotation in every position have the shingled stream.
  • the toothed belts are provided with a plastic coating on the outside.
  • the material to be used can also be selected with regard to the lowest possible coefficient of friction.
  • the device 1 shown in FIGS. 1 and 2 in accordance with the preferred exemplary embodiment for the lateral alignment of printed product 3 located on a conveyor 2 has a frame 4 to which two motor-driven alignment units 5 and 6 are fastened at an adjustable distance from one another.
  • the frame 4 of the device 1 has two rods 7 and 8, which are guided under the conveyor 2 transversely to the conveying direction thereof, for the stable connection of the two alignment units.
  • the device can thus be set to any width of the delivered printed product or to different widths of the scale flow.
  • the two screw terminals 9 and 10 are in turn connected to one another via a support 11 of a support structure of the alignment unit 5 and 6, respectively.
  • a gear 12 for example a bevel gear
  • a plummer block 14 for a vertically loosely rotatably mounted second shaft 15 has been arranged, which is non-rotatably connected to a pulley 19 or 19 'which is also designed in the manner of an eccentric and is provided with an eccentric bore.
  • a toothing 20 is provided, into which an endless toothed belt 21 or 21 'connecting the two pulleys 18 and 19 or 18' and 19 'to one another is provided. engages with its teeth 22.
  • the eccentricity of the two pulleys 18 and 19 or 18 'and 19' is essentially the same size and is in phase with one another with respect to a common angle of rotation.
  • Both pulleys 18 and 19 or 18 'and 19' which are designed as eccentrics, are thus connected to one another via the endless toothed belts 21, 21 'in such a way that they are always at the same distance from the conveyor 2, which is preferably designed as a belt conveyor, in each position with a full revolution or from a scale stream 24 formed from the printed product 3 (approximate phase coherence).
  • the two alignment units 5 and 6 are designed in the same manner as described above.
  • the two gears 12 of the two units 5 and 6 are mechanically connected to one another via a drive (not shown) on a connecting shaft 23.
  • the eccentric pulleys 18, 18 'and 19, 19' are placed in pairs so that they work in opposite directions and the two toothed belt drums 25, 25 'perform a stroke that leads towards and away from each other.
  • the two alignment units 5 and 6 can also be operated as a whole by only one motor arranged on one of the two units, but also by means of a gear shaft driving both units, which in turn is driven decentrally by a motor.
  • the decentralized drive can be tapped from the conveyor to synchronize the alignment units.
  • the desired distance between the two alignment units 5 and 6 - as already mentioned at the beginning - can be set with the help of the screw terminals 9 and 10 as required.
  • the frame 4 of the alignment device 1 and the two alignment units 5 and 6 of the same are designed such that one strand 25, 25 'of the two toothed belts 21, 21' on the Conveyor 2 facing side over its entire length is arranged parallel to the conveyor 2, ie running to the conveying direction of the shingled stream 24, and that they form a U-shaped channel with the conveyor 2, viewed in cross section, in which the continuous shingled stream 24 is aligned on both sides becomes.
  • the two toothed belts 21, 21 ' have a width such that their upper edge 27 projects beyond the printed product 3 located on the conveyor 2.
  • the toothed belts can be provided on their outside with a special plastic coating, for example with a Teflon coating. Such a coating can also reduce the coefficient of friction of the belt surface.
  • the described holding device for the alignment units 5 and 6 with the frame 4 and the adjusting elements 7, 8 and 9, 10 for adjusting the alignment units to different widths of the printed product can also be arranged overhead with respect to the conveyor 2, which increases the mobility of the whole Device still favored. In this way too, the two alignment units form a U-shaped channel together with the conveyor.
  • the operation of the alignment device described in FIGS. 1 to 3 is as follows: According to the embodiment described for FIGS. 1 and 2, the toothed belt 21 arranged on the two alignment units 5 and 6 is driven via the gear 12 and with the aid of a drive motor via the pulley 18 on the side of the run 25 a movement in the direction of the arrow 16 is given at a speed which corresponds to the direction of movement and the conveying speed of the conveyor 2.
  • the two toothed belts 21, 21 ' are set with a full rotation of the pulleys in the position shown in Figure 1 with a dash-dotted line 17 and push it here Print product 3 of the stream of shingles 24, such as left and right hands, arranging laterally during the conveying process. After reaching the position of the toothed belts 21, 21 'drawn with the dash-dotted line 17, they are returned to the position drawn with a solid line. - With a further rotation of the pulleys 18 and 19, the above-described movement sequence of the two toothed belts 21 is repeated.
  • the toothed belts of the alignment units describe a stroke running vertically to the scale flow.
  • the runs 25, 25 'running along the shingled stream 24 approach each other to the shingled stream width and push individual disordered shingled stream elements together with a minimal conveying speed in the conveying direction to form an equally wide strand of printed products.
  • the disordered stream of shingles pushes into the now wider U-shaped channel and is pushed together again in the next stroke before it has passed through the alignment device.
  • the toothed belts run almost at the shingled stream speed when pushed together, so that no unpredictable disorder can occur during the pushing together or if the shingled flow elements come into contact with the toothed belt, e.g. by pushing the shingled flow elements together in the conveying direction (change in the shingled spacing). This happens alternately at a speed that is adapted to the printed product conveyance.
  • FIGS. 3A and 3B still show procedural details for the operation of the device according to the invention. These process details also provide information on the dimensioning of functional parts when designing the device and also on the estimation of approximate operating variables such as speeds, timing, etc.
  • FIG. 3A shows the speed change of the rotating toothed belt in a speed-time diagram, for example as a moving point on the Viewed parallel to the printed product 3 tooth belt 25 or 25 'over a full revolution of the eccentric pulley 18 or 19.
  • the position 0 degrees corresponds to the position of the pulleys, as shown in Figure 1.
  • Vmin (25) and Vmax (25) denote on the one hand the minimum speed of a point on the run 25, that is the basic speed v0, and on the other hand its maximum speed when touching the printed material during the order stroke.
  • the ratio VminNmax depends on the eccentricity. Example: with a pulley diameter of 6 cm to 7 cm and an eccentricity of approx. 1: 2, at approx. 200 rpm, speeds of Vmin approx. 0.4 to 0.5 m / s and Vmax 0.8 to 1.0 m / s, with a simultaneous stroke result of about 2 cm.
  • An oblique printed product 3 (within the scale flow) is to be aligned by means of an opposing stroke movement of the toothed belt strands 25, 25 '.
  • the printed product which is also inclined to the required scale spacing S, should finally have its original scale spacing in the correct position.
  • the alignment device not only corrects skewed printed products into ordered positions, but also lateral displacements, as can occur when they are output from rotary printing. Such shingled streams that are shifted in this way are centered on the conveyor in the lateral direction.
  • the «rotating» alignment planks (the toothed belt), in contrast to fixed planks, keep the differential speed within limits (v3 to Vmin (25)) and thus enable the product conveying speed to be increased practically at will.
  • the eccentricity achieves the order stroke, which is also superimposed on the toothed belt speed as an increase in speed.
  • the stroke and ripple of the overall speed can be determined using the eccentricity ratio.
