Definitions

  • the present invention relates to an erecting device of flat shipments according to the preamble of the claim 1.
  • DE 1 817 472 U describes a device for rotating flat shipments around a perpendicular to their plane Axis standing on an edge with a belt system be transported on a cover tape.
  • a driven pair of rollers whose common axis is substantially perpendicular is arranged to the conveying direction, the first roller above the cover tape and the second roll below the Shroud is arranged.
  • the upper roller has a higher, fixed rotation speed than the lower roll, so that the position of the broadcast changes Moment is exercised. A targeted alignment of Shipments are not possible with this.
  • a device for aligning sheets (EP-A-0 431 267) is using a sensor device Location of the respective shipment determined. Becomes a lean detected, the two of those are activated several roles, the engagement of which best effects alignment. A roll will then run at a fixed speed driven and the other roller braked until the inclination is balanced. A regulated change of speeds of the rolls according to the type and size of the Inclination while maintaining the distances between the Shipments are not made here.
  • the object of the present invention is to provide a device for the alignment of flat consignments, which means of a conveyor system, in particular Gaps between the shipments can be avoided.
  • the invention is based on the idea of broadcasts during the Alignment process by a controllable pair of rollers frictionally grasp and by changing the rotational speed or the Orientation of the roles and the position of the shipments relative to Tape system to exert a changing moment on the programs. Thereby is a straightening section regardless of its installation position.
  • the device according to the invention it is possible to shift gaps to avoid and difficult shipment types too to edit. In particular, it is avoided that shipments are damaged overall, the entire mail distribution system becomes susceptible to faults reduced.
  • the in FIG. 1 has a belt system consisting of the base belt 1 and the cover belt 2, which conveys a flat mail item 3 standing on one edge. Rollers 4 are provided for guiding and driving the belts. In normal operation, the shroud has a nominal speed VN. A pair of rollers 5 and 6 with a common axis of rotation 7, which is arranged substantially perpendicular to the conveying direction of the mail items, is arranged above and below the cover band 2. Since the consignment 3 is only covered by the cover tape at the rear, the rollers 5 and 6 can rest against the consignment 3 and grasp them by friction.
  • one of the rollers can preferably rotate at a speed corresponding to the nominal speed Vn, while the second roller has a speed deviating therefrom V.
  • the difference between the two speeds leads to the formation of a torque on the item, so that a position correction can be made if necessary.
  • the upper friction roller 5 is driven by a servo motor; the lower roller sits directly on a hollow shaft on the motor axis with the nominal speed V n .
  • This second roller is preferably driven by a belt 8 and a pulley 9, FIG. 2nd
  • the position of the shipment is determined by two in the conveying direction in front of the pair of rollers 5, 6 arranged sensors 10 detects. Preferably for that Light barriers provided. With a further sensor device 11 Location of the shipment while it is held by the reels 5 and 6 detected.
  • the sensors 10 and 11 are not the same as in FIGS. 1 and 2 control electronics shown connected.
  • a counter roller 13 by a solenoid 12, which is a Axis 14 is pivotable and presses against the cover band 2, moved away, as soon as the shipment is to be moved in relation to the conveyor system.
  • FIG. 3 shows a further embodiment of the invention with a pair of rollers 15, 16, which is arranged on a common pivotable axis 17.
  • the axle sits on a chassis 19 which is articulated at a pivot point 18 is.
  • the pivoting movement is preferably via a rack and a gear 21 driven by a servo or stepper motor.
  • a motor 22 drives the belt 23 and a pulley 24 Axis 17 on.
  • FIG. 4 shows the device of FIG. 3 in top view.
  • a spring-loaded counter roller 25 is opposite the pair of rollers 15, 16 arranged to improve the frictional version of the program 3.
  • the Counter roller 25 is arranged on the same chassis as the pair of rollers 15, 16.
  • the roller 25 is moved away by a Hubmgnet to the To facilitate movement of the shipment between the shroud 2.
  • the roles 15 and 16 are at a speed corresponding to the nominal speed Vn Rotational speed driven so that one of the rollers 15 and 16th recorded consignment can be moved by pivoting the axi
  • FIG. 5 shows the case of a shipment whose rear edge is raised.
  • the rear edge of the mail item is moved in the direction of the base belt 2.
  • the roller 5 is then driven at the speed Vn.
  • Figure 5b shows the case of a shipment with the leading edge raised.
  • 5c shows the case of a shipment that is raised horizontally on the base band, in this case there is a speed in the front area of the shipment V sent, which leads to a lowering of the rear edge of the broadcast. Then, as in FIG. 5b a speed + V applied, which leads to a lowering of the leading edge. During this straightening process, a shipment of rolls is gripped so that there is no gap shift between the shipments.
