Definitions

  • the invention relates to a turning device for single sheets the preamble of claim 1.
  • Such turning devices are for example in folding machines known and serve, for example, single sheets for an inserting process to compile in sentences.
  • the order of fed single sheets is determined by the continuous printing. Thereby can further processing in a subsequent machine or station problems if the printed image is on the wrong one Side of the cut sheets.
  • the invention is based, the generic turning device the task to be designed so that the single sheets are transported in this way can be that they are flawless in the subsequent station can be processed further.
  • the suction element enables a rapid transport of the single sheet after it 180 ° turn.
  • the turning device therefore has a high performance. It can be increased by the fact that the suction element is set so that the single sheets transported by it each other overlap.
  • the invention is based on an embodiment shown in the drawing explained in more detail.
  • the drawing shows a side view and a schematic representation an inventive turning device for single sheets.
  • the turning device has an endless conveyor belt 1 that over two pulleys is guided. Of them is only in the drawing the axis of rotation 2 of a deflection roller is shown. With the Conveyor belt 1 are single sheets 3 in the direction of arrow 4 with little Distance transported from each other. In the area above the Upper run 5 of the conveyor belt 1 are spaced apart Rollers 6, which are at the same height and their axes 7 run parallel to the axis of rotation 2 of the deflection rollers. The roles 6 ensure that the cut sheets 3 are reliable on the conveyor belt 1 can be transported. The rollers 6 can be rotatably driven be so that they the single sheets 3 together with the conveyor belt Transport 1 in the direction of transport 4.
  • a deflection plate 8 At the front deflection area in the direction of transport 4 there is a deflection plate 8 provided the small distance from the conveyor belt 1 has and ensures that the single sheets 3 reliably turned by 180 ° become. One of the single sheets is in the drawing 3 in this deflection area below the deflection plate 8.
  • the baffle 8 runs coaxially to the corresponding area of the conveyor belt 1 to approximately the level of the axis of rotation 2 the horizontal plane containing the deflection roller.
  • a roller 11 is arranged, the axis 12 parallel to Axis of rotation 2 of the adjacent deflection roller runs.
  • Roll 11 is advantageously provided with knurling on its lateral surface, which extends parallel to the roller axis 12.
  • the end 10 of the baffle 8 extends close to the outer surface of the roller 11. This it is ensured that the single sheet 3 is reliable in the deflection area is transported further in a manner to be described.
  • a support 13 which is horizontal in the embodiment runs and over the deflection area of the conveyor belt 1 after protrudes in front and back.
  • the edition 13 provided with a stop 14 on which the turned single sheet 3 comes with one end 15 to the system.
  • the stop 14 is advantageously in one piece with the sheet or plate-shaped support 13 trained and formed by a bend. In the embodiment the stop 14 closes an acute angle with the support side 16 of edition 13 a.
  • the stop 14 from the support side 16 from obliquely against the lower run 17 of the conveyor belt 1 is directed and the support side 16 is only a small distance from the deflection area of the conveyor belt 1, the lower run 17 runs of the conveyor belt 1 from the front deflection area in the transport direction 4 from diagonally towards the upper run 5.
  • the stop 14 can also be arranged so that the lower run 17 runs parallel to the upper run 5.
  • the distance between the roller 11 and the stop 14 advantageously set.
  • This can the transport unit 1 with the baffle 8 and the roller 11 and / or the support 13 and / or the stop 14 relative to one another can be set.
  • Suction drum 18 In the area below the pad 13 close to the stop 14 is one Suction drum 18 provided, the axis of rotation 19 parallel to the axis of rotation 2 the pulley is located.
  • the deflection roller of the conveyor belt 1 and the suction drum 18 have the same direction of rotation (arrows 20 and 21).
  • the suction drum 18 is designed in a known manner and on a vacuum source (not shown) connected with which in the suction drum 18 a negative pressure is produced.
  • the outer surface 22 of the suction drum 18 has openings (not shown).
  • the Pad 13 is in the area of the suction drum 18 with at least one Provide opening (not shown). This ensures that the negative pressure on the single sheet 3 on the edition 13 can act, which thereby pulled firmly against the support side 16 becomes. Since the suction drum 18 rotates in the direction of rotation 21, this will initially Single sheet 3 abutting stop 14 in the direction of arrow 23 transported on the edition 13.
  • suction elements 18 can also be used are used, such as an endlessly rotating suction belt, with which the turned single sheets 3 with the support of Vacuum can be transported in the direction of arrow 23.
  • the Suction tape is provided with openings so that the vacuum on the Single sheets 3 can act.
  • the individual sheets 3 are initially one after the other with a small distance over the deflection roller of the conveyor belt 1 under the deflection plate 8 transported.
  • the roller 11 ensures that the rear edge 24 of the single sheet 3 is deflected cleanly downwards and not collides with the following single sheet 3.
  • the single sheet 3 comes with its front edge 15 to the stop 14 and it will stop.
  • the suction drum 18 transports this on the Edition 13 filed single sheet 3 again in the original direction 23 on edition 13.
  • the transport speed on the Edition 13 is much slower than the transport speed of the conveyor belt 1.
  • the single sheets 3 come on the Edition 13 to lie on each other like a scale, as in the drawing is shown.
  • the single sheets are in this stream of shingles 3 turned by 180 ° compared to the position on the conveyor belt 1.
  • the order of the single sheets 3 has been after the 180 ° turn not changed.
  • the vacuum is generated by means of the suction drum 18 clocked. At the entry of the first single sheet 3 of the shingled stream the vacuum is turned off at the inlet of this first Cut sheet 3 not to hinder.
  • the rotational speed of the Suction drum 18 is clocked and so slow that the suction drum 18 does not become free before the following single sheet 3 at the stop 14 is present. Should the distance between successive Single sheets are larger, the suction drum 18 is stopped before it becomes free.
  • Photoelectric sensors are used, which are in the range of motion of the Single sheets 3 on the conveyor belt 1 or in the area of the stop 14 are arranged and depending on the distance of the Send single sheets 3 signals from one another to a control device, with which the clock of the suction drum 18 is controlled. This is ensures that a single sheet 3 is always on the suction drum 18 rests and it does not become free.
  • the transport device described ensures that the order of the single sheets fed is maintained and the position of the printed image in the downstream of the transport device Machine is correct. Due to the 180 ° turn the single sheets 3 in the necessary for further processing Position on the following machine.
  • the speed of the suction drum 18 can be controlled that the turned single sheets 3 each other during further transport do not overlap, but have a distance from each other, for example.
  • the suction air is clocked with each single sheet 3, i.e. off.
