Definitions

  • the invention relates to a device for reversing the direction of flat shipments in consignment sorting systems with feeding and discharging cover belt conveyors.
  • this distribution information must be in fixed positions. If this is not the case, the consignments must be brought by rotation about their longitudinal and / or vertical axis in the working position.
  • JP-A-61-64658 a device for reversing the direction of flat objects by means of rollers described.
  • the successively supplied items alternately passed over a switch in two reversibly driven conveyor lines. While an object is being transported in the one conveyor line, the respective preceding object is simultaneously conveyed out of the other conveyor line again.
  • the invention has for its object to provide a low-cost device for reversing the direction of flat shipments in consignment sorting with incoming and outgoing shroud conveyors, with a collision-free rotation of flat, with small intervals successive programs is possible about its vertical axis.
  • the feeding shroud conveyor consisting of two endless circulating belts, between which the shipments are trapped in a row, follows a switch for splitting the programs alternately on two apart at an acute angle Deckbandtransportrangen with two endless belts, which each one controlled and reversible drivable conveyor line, in which the items are also transported clamped, connects.
  • Both conveyor sections can be driven by a drive roller arranged between them and the items can be guided around the drive roller in such a wrap angle that the items can be braked and accelerated approximately slip-free, taking into account the frictional forces.
  • Each conveyor line is designed so that the items can be routed during return transport at an acute angle to the respective feeding shroud transport path in a laxative shroud transport means with two endless, circulating belts.
  • the braking process is only started when the trailing edge of the respective program has left the shroud transport path. At any time, the broadcasts are frictionally guided in the device.
  • a further possibility for the low-effort execution of the controlled and reversibly drivable conveyor lines, but with limited range of broadcast formats, is to provide for these in each case an outer, endless shroud, which is guided over two pulleys, and the common drive roller.

  • the left shroud transport path also consists of a third endless belt 9, which is deflected and returned via a third deflection roller 10, and a fourth endless belt 11, which is deflected and returned via a fourth deflection roller 12.
  • Each shroud conveyor route directs the shipments into a controlled and reversibly driven conveyor line. Both conveyor lines converge in the inlet direction at an acute angle.
  • the conveyor belt section following the right conveyor belt conveyor consists of a fifth, outer endless belt 15, which is deflected by two deflection rollers 16 and a sixth, inner endless belt 17, which runs over a larger drive roller 18 and a smaller guide roller 19.

  • the deflection rollers 16, 21 of the conveyor lines located close to each other are at such a distance from one another that the thickest packages 30, 31, 32 that do not need to be transported back or that are longer than the reversible conveyor line, pass through the gap between the deflection rollers 16, 21 can be fed freely to a following means of transport. Since the transport directions of the shroud transport paths and the respective subsequent conveyor lines are inclined to each other, there is a necessary angle of wrap, with which the programs 30,31,32 are guided around the drive drum 18. Since the conveyor lines are inclined inwards, the consignments 30,31,32 are passed on the outside back to the feeding Deckbandtransportrangen and the feeding Deckbandanisch 1 on both sides in laxative Deckbandtransportstoff.

Abstract

L'invention concerne un dispositif comprenant deux voies de transport (50, 51) à sangle présentant un sens de transport réversible, lesquelles sont entraînées par un rouleau de commande (18) commun. Les marchandises (30, 31, 32) du flux de marchandises sont réparties alternativement sur les voies de transport (50, 51) à sangles. Les marchandises transportées en retour (30, 31, 32) sont dirigées dans un moyen de transport (60, 61) à sangle. Le rouleau de commande (18) est commandé, de manière à ce qu'au départ d'une marchandise suivante (32) sur une voie de transport (50, 51) à sangle, la marchandise (31) transportée en retour est activée à une vitesse nominale, puis le processus de ralentissement est activé, lorsque le bord arrière de chaque marchandise (32) a quitté la voie de transport (40, 41) à sangle et que la marchandise précédente (31) n'est plus calée dans une voie de transport (50, 51) à sangle commandée et réversible.
