Definitions

  • the invention relates to a device for rotating sheets of paper by a rotation angle of preferably 90 ° in a conveyor track, which has in a horizontal plane conveying means in the form of rollers or endless conveyor belts and slide rails and a longitudinal guide rail, the frictional pressing of the paper sheets on the conveying means Pressure balls are provided, which rest loosely rotatable in cylindrical ball cages on the funding.
  • the invention has for its object to provide the simplest possible device of the generic type, with which it is possible to rotate the individual sheets of paper during their transport from one machine to the second machine without changing the conveying direction by an angle of 90 °, wherein this rotation should also take place at high conveying speeds without damaging the paper sheets, in particular the leading edges of the paper sheet.
  • This object is achieved according to the invention in that in the conveying direction directly in front of the conveying run of a conveyor belt guided in the vicinity of the longitudinal guide rail over a belt roll, on which a plurality of pressure balls arranged in a longitudinal row lie, in the row of these pressure balls a stop roller driven against the conveying direction is arranged with a pressure ball and that immediately before this stop roller is laterally offset to the center of the conveyor track a drive roller driven in the direction of conveyance is arranged, on which a pressure ball rests with a greater contact pressure than the pressure ball of the stop roller .
  • Claims 1 to 8 each relate to advantageous embodiments of the invention, by means of which both the working speed and the functional reliability can be increased.
  • the device shown in the drawing is a conveyor track 1 lying in a horizontal plane with a sheet turning station 2, through which incoming paper sheets 3 are rotated by 90 ° in landscape format and transported along a guide rail 4 in the longitudinal format.
  • the paper sheets 3 arriving in landscape format first pass through a conveyor track section A, which is laterally delimited by two guide strips 5 and 6, and then through a conveyor track section B in longitudinal format, which directly adjoins the sheet turning station 2.
  • the distance b between these guide strips 5, 6 corresponds approximately to the length L of the paper sheet 3.
  • this conveyor track section A there are two shafts 9 and 10, each at a distance and symmetrical to the center of the conveyor track 38, in front of the sheet turning station 2 on two shafts 9 and 10 running transversely to the direction of arrow 8
  • On these conveyor strands 15 ', 16' of the conveyor belts 15 and 16 each have 2 pressure balls 18 which are freely rotatably arranged in stationary guide cages 17 and hold the paper sheets 3 passing underneath them in frictional contact with the conveyor belts 15 and 16, respectively.
  • a plurality of slide strips 19, preferably made of sheet metal, are arranged between these conveyor belts 15 and 16 and next to them.
  • the rotating station 2 arranged at the end of the conveyor track section A is provided with two shafts which are arranged directly next to one another and parallel to one another and are driven in opposite directions, namely a forward rotating, i.e. rotating drive shaft 20 with the same direction of rotation as the shafts 9 and 10 and with an opposite direction provided in the reverse direction rotating stop shaft 21.
  • a stop roller is fixedly arranged on the stop shaft 21, which has a friction jacket 44 made of rubber or the like and which is arranged directly in front of a conveyor belt 23 running along the guide rail 4, on the upper conveyor run 23 'of which a plurality of pressure balls 25, 26, 27, 28 and 29 rest loosely with their own weight, which are freely rotatably mounted in stationary ball cages 24.
  • the upper conveyor run 23 ' is supported by a support bar 30.
  • the conveyor strand 23 ' has the same direction of conveyance of the arrow 8 on as the conveyor runs 15 'and 16' of the conveyor belts 15 and 16.
  • the conveyor belt 23 is guided over a belt roller 31 which sits on a shaft 32 and has the same direction of rotation as the belt rollers 11 to 14, which refer to Figure 2, turn clockwise.
  • this pressure ball 33 is made of a material with a high specific weight, for. B. made of steel.
  • a drive roller 34 is arranged in a rotationally fixed manner on the drive shaft 20, which, in relation to FIG.
  • a paper sheet 3 arriving, for example, with its front transverse edge 40 at the contact point 41 between the pressure ball 33 and the stop roller 22 is first stopped at this contact point 41.
  • the drive roller 34 whose point of contact 42 with the pressure ball 35 has already passed through the front edge 40 of this sheet of paper 3, provides further conveyance, which according to FIG. 3 results in a rotary movement of the sheet around the point of contact 41.
  • the front edge 40 of the paper sheet 3 is pushed into the contact point 41.
  • the paper sheet 3 is moved backwards against the normal direction of rotation.
  • stop roller 22 and the drive roller 34 have a lower peripheral speed than the belt rollers 11 to 13 and 31 respectively. It is optimal if this peripheral speed of the stop roller 22 and the drive roller 34 is approximately half as large as the conveying speed of the conveyor belts 15, 16 and 23 and the peripheral speed of the belt rolls 11 to 14 and 31.
  • the first two or three pressure balls 25, 26, and 27 of the conveyor belt 23 are made of plastic, ie they rest on the conveyor strand 23 'of the conveyor belt 23 with a relatively low contact pressure, so that the original front edge 40 of the sheet of paper 3 can be easily pushed underneath without being damaged.
  • the pressure balls 25 to 29, which rest on the conveyor run 23 'of the conveyor belt 23, can be lighter overall, since they are present several times and therefore can still ensure the required frictional connection between the paper sheet 3 and the conveyor belt 23.
  • a second one is located directly in front of the stop roller 22 on the drive shaft 20 a friction jacket provided conveyor roller 39, on which the paper sheet 3 lies loosely, but which comes into frictional connection with the underside of the paper sheet 3 so strongly that it constantly pushes the paper sheet against the contact point 41.
  • stop roller 22 with its pressure ball 33 is laterally offset relative to the drive roller arranged in the center of the conveyor track 34 to the level of the guide rail 4 by an amount that is approximately a quarter of the width or length L of the incoming Transverse edge 40 of the twisting paper sheet 3 or the conveyor track width b corresponds.
  • the drive roller 34 can be displaced on the drive shaft 20. It is also advantageous to provide the stop roller 22 and / or the drive roller 34, as shown in FIG. 5, with a spherical outer surface 44 so that no linear but small circular contact surfaces can arise between the paper sheet 3 and these outer surfaces. This favors the turning process.
  • the contact pressures with which the contact balls 33 and 35 rest on the outer surface of the stop roller 22 or drive roller 34 assigned to them can, according to experience, be dependent on the paper quality, whereby smooth paper requires a greater contact pressure than relatively rough paper.
