Definitions

  • the invention relates to a Rundstapelbogenanleger with the features of the claim 1.
  • Fig. 1 and 2 schematically show a known round stack sheet feeder 10, which has an upper table 12 and a sub-table 14, which are arranged one above the other and between them a turning device 16 is provided, which conveys a stack of sheets conveyed on the upper table 12 18 turns and places on the lower table 14.
  • the lower table 14 has as a feed device a conveyor belt 20, through which the sheet stack 18 in the direction of an a transfer point 21 arranged singulator 22 is conveyed, the one Suction wheel 26 which sucks the most downstream bow 42 and to a further transport device 24 delivers.
  • a two-armed rocker 32 is provided, which is about a pivot axis 38 is pivotable.
  • the upper arm 34 of the rocker 32 extends adjacent to the transfer point 21 beyond the conveying plane FE and is the impact of the most downstream Arc 42 of the sheet stack 18 is pivoted in the conveying direction.
  • the other, downwardly extending arm 36 of the rocker 32 approaches in this pivoting an analog sensor 40, which has a dependent on the distance of the second arm 36 output voltage to a control device (not shown) which determines the feed rate the conveyor belt 20 in response to the output voltage at the Control device controls.
  • the feed rate at the pivoting the rocker 32 in the conveying direction is further reduced until the second arm 36 to the analog sensor 40 stops and the feed is stopped.
  • a suction valve 28 of the suction wheel 26 is activated so that the foremost, most downstream arc 42 of the suction wheel 26th is tightened and then stored on the further transport device 24. To a suitable Time the suction valve 28 is turned off again.
  • the synchronization between Suction wheel 26 and the feed is designed so that at the time of activation of the Suction valve 28 always a bow 42 abuts the transfer point 21.
  • the sheets do not always have the same shape the rocker 32 arrive. They can be scaled to different heights or even upwards or rounded down as shown in Figures 3 and 4. Especially Upwardly curved sheets ( Figure 3) are a problem as they contact the upper arm 34 can overlap the rocker 32.
  • the foremost sheet 42 means are provided, through which a guide plate 48 can be adjusted in height at the transfer point 21, as indicated by the Double arrow is shown in Figures 3 and 4.
  • the rocker 32 is in height adjustable to adjust the upper arm 34 so that it more or less on the Conveyor plane extends beyond.
  • these measures are structurally very expensive.
  • the adjustment also requires a great experience of an operator much time.
  • the invention is based on the object with structurally simple means a Rundstapelbogenanleger to create a safe decrease of a downstream arc ensured at the transfer point to a further transport device.
  • the distance becomes the most downstream Arc of the transfer point detected contactless and a distance corresponding Detection value passed to a processor device, which determines the feed rate the feed device controls the distance accordingly. Due to the Non-contact detection need no action to adapt to the shape of the sheet leading edge be taken as in the above-described prior art of Case is. There is little constructive effort required. In addition, the otherwise for adjustment required time to be saved.
  • the non-contact detection device is preferably provided by a light scanner, e.g. a light curtain formed as a detection value one of the cover by the downstream bend dependent voltage, e.g. 0 to 10 volts to the processor device for controlling the feed rate passes.
  • a light scanner e.g. a light curtain formed as a detection value one of the cover by the downstream bend dependent voltage, e.g. 0 to 10 volts to the processor device for controlling the feed rate passes.
  • the detection value may also be one of the coverage by the most downstream arc dependent current value, a serial data interface or a parallel interface.
  • the non-contact Detection device preferably provided a double-arc sensor at the transfer point which, upon detection of a double sheet, sends a corresponding signal to the Processor device for switching off the feed device user exterior.
  • a double-arc sensor For example, the ultrasonic double-sheet control system UDC-18GM-400-3E3 be offered by the Pepperl + Fuchs GmbH.
  • one is the trailing edge of one on the forwarding device provided transported sheet detecting detection device, the upon detection of the trailing edge, send a signal to the processor means for controlling the arc gap passes.
  • the processor device a medium Feed rate then the feed drive as a speed setpoint is handed over. This setpoint is determined by the processor device so that the feed device works as smoothly as possible.
  • the feed rate can in another embodiment by the processor device also be calculated by means of the clock sequences of the double-bow sensor. Of the sheet stack runs fast at first, depending on the reaction behavior can then be a continuous Speed be adjusted.
  • the Rundstapelbogenanleger invention is essentially constructed as the With reference to Figure 1 described Rundstapelbogenanleger 10.
  • An essential difference is that instead of the rocker 32 formed by a light curtain light sensor 52 at the transfer point 21 below the conveying plane at the transfer point 21 is arranged, which is the distance of the front edge of a downstreammost arc 42 of a from the feed device 20 conveyed sheet stack 18 from the transfer station 21st detected.
  • the light sensor 52 is an analog sensor, which depends on the cover by the Sheet 42 passes a voltage value to a processor device 50, preferably between 0 and 10 volts. The output voltage of 10 volts is passed on, if there is no arc 42 above the light scanner 52.
  • the suction valve 28 of the Saugrades 26 is of the Processor device 50 is activated, so that the most downstream arc 42 of the suction wheel 26 is tightened and stored on the further transport device 24.
  • an ultrasonic double-arc sensor 54 is provided below the transfer point 21.
  • This ultrasonic double-arc sensor 54 radiates an ultrasonic pulse from below, which excites the bow to vibrations. These vibrations cause the spread of a very small sound wave on the other side of the arc, from one opposite Ultrasonic receiver 56 is evaluated. For superimposed bows (Double sheet), the signal is so attenuated that it barely reaches the reception.
  • the ultrasonic double-sheet sensor 54 can detect whether no sheet, a sheet, or more than a bow at the transfer point 21 are. Once the ultrasonic double-arc sensor 54 recognizes that more than one arc is located at the transfer point 21, It sends a corresponding signal to the processor device 50, which then feed the conveyor belt 20 stops and outputs an alarm signal to the operator. hereby Prevents overlapping bow on the forwarding device 24 are stored.
