Definitions

  • Transfer device for general cargo in particular for postal cargo
  • the machine-readable postcodes to be indicated on postal items such as letters, postcards, parcels and the like as a code number for a post location enable a rapid mechanical distribution of the post.
  • the incoming mail items are sorted with the aid of controllable parcel carriers, which are loaded in each case in special input places with a mail item and then deliver this mail item to a sorting container assigned to the respective postcode or a corresponding sorting compartment. Since the sorting containers or sorting compartments can be arranged on different levels, the piece goods carriers rotating around conveying devices may also have to be able to bridge different heights.
  • the empty general cargo carriers can be reloaded with mail items as they pass an input location. When transferring the mail to the sorting device described above, this must be on a conveyor, such. B. mail arriving at a belt conveyor is specifically and preferably individually delivered to the general cargo carriers passing at a relatively high speed.
  • the invention specified in claim 1 is based on the problem of creating a simply constructed transfer device for mail, with which the mail arriving on a conveying device can be reliably delivered to rotating piece goods carriers of a sorting device.
  • the transfer device can also be used, for example, in storage systems or automatic picking machines for comparable tasks, in which items arriving on a first conveyor device, with codes provided piece goods is to be transferred to piece goods carriers of a second conveyor device.
  • the invention is based on the knowledge that an impeller with preferably fixed vanes on the one hand enables a safe reception of the piece goods arriving on a first conveying device, and that on the other hand by coordinating the peripheral speed and circumferential pitch of the impeller with the speed and pitch of the rotating piece goods carrier is also guaranteed a targeted transfer of the piece goods to the individual piece goods carriers.
  • the embodiment according to claim 2 enables a direct transport of the piece goods into the cells of the impeller by segmenting the impeller and the first conveying device.
  • the transfer of the piece goods from the first conveying device to the cells of the impeller is thus reliably manageable , because in particular a throw dependent on the shape and mass of the piece goods can be dispensed with.
  • the embodiment according to claim 3 offers the possibility of safely transporting the piece goods to the rear end of the pharynx-shaped cells of the impeller.
  • guiding the segments of the first conveying device over deflecting wheels of the impeller requires greater maintenance effort than an embodiment with segments of the first conveying device which project freely into the cells of the impeller.
  • the development according to claim 4 enables parallel alignment of the wings and the first conveying device in the delivery area, so that the piece goods can be lifted extremely gently from the respective wing parallel to the conveyor.
  • the tangential alignment of the wings enables the cells in the transfer area to be adapted to an inclination of the circulating general cargo carriers and thus a particularly secure transfer of the general cargo to the peripheral general cargo carriers.
  • the embodiment according to claim 5 enables a permanent adjustment and adaptation of the impeller to the division of the piece goods carrier even if there are gaps between individual groups of piece goods carriers. Such gaps arise, for example, when several piece goods carriers are attached to rotating carriages of the second conveyor.
  • the preferred embodiment according to claim 6 enables the piece goods to be transported on the further conveying device at a predetermined pitch and a transfer of the piece goods to the first conveying device while maintaining this pitch.
  • the spacing of the piece goods can be specified, for example, by transversely oriented tunnels of the further conveyor device, these tunnels then dipping downward in the area of the transfer to the first conveyor device. A compression or other mechanical impairment of the piece goods by the cleats in the area of the cells of the impeller is thus avoided.
  • the development according to claim 7 enables permanent adjustment of the speed of the incoming piece goods to the peripheral speed of the impeller.
  • the guiding means according to claim 8 prevent the piece goods from falling out of the cells in the circumferential area of the impeller lying in front of the delivery area with certainty. If the guide means are formed according to claim 9 by an endlessly circulating belt, then there is a risk of mechanical impairment of the piece goods be excluded with certainty because the belt runs automatically and at the same speed.
  • FIG. 1 shows a transfer device for general cargo equipped with an impeller
  • FIG. 2 the transfer device according to FIG. 1 with a common drive of the impeller and the incoming conveying device and
  • FIG. 3 shows the segmentation of the impeller and the incoming conveying device leading into the cells of the impeller.
  • FIG. 1 shows a transfer device for piece goods in a highly simplified schematic representation.
  • This transfer device comprises a revolving impeller FR, the vanes F of which are fixed around the wheel axis RA indicated by a cross and form sector-shaped cells Z which receive the piece goods S arriving on a first conveying device FEI and on rotating piece goods carriers ST of a second conveying device FE2 submit.
  • the piece goods S indicated by chain-dotted lines are, for example, letters which are placed at three feed points from above onto a further conveying device FEW indicated only by a dash-dotted line. From there, the piece goods S are then transferred to the first conveyor FEI and transported directly into a cell Z of the impeller FR.
  • an endless belt BE prevents the piece goods S from falling out of the cells Z.
  • the guided over a total of three roles RO endless belt EB is frictionally driven by the impeller FR, whereby an undesired relative movement between the endless belt EB and the piece goods S is avoided.
  • the piece goods S then fall out of the cells Z in the delivery area into the associated piece goods carriers ST of the second conveyor FE2.
  • the tangential orientation of the vanes F with respect to an imaginary inner circle of the impeller FR enables adaptation in the transfer area to the inclination of the piece goods carriers ST.
  • the piece goods carriers ST of the second conveyor FE2 are components of a sorting device for mail, the structure and mode of operation of which are described, for example, in the earlier patent applications P 43 23 564.6 and 43 23 565.4.
  • the speed vl and the division distance tl of the piece goods S arriving on the further conveying device FEW and the first conveying device FEI, the peripheral speed u and the circumferential pitch t2 of the impeller FR and the speed v3 and the pitch t3 of the rotating piece goods carriers ST are matched to one another in such a way that a consistently safe transfer of the piece goods S is always guaranteed.
  • the speed vl and the division distance tl of the incoming piece S are selected such that the next empty cell Z of the impeller FR rotating at a constant angular velocity can be loaded.
  • the circumferential pitch t2 of the wing F of the winged wheel FR and the pitch t3 of the piece goods carrier ST are matched to one another, as are the pitches of the toothed wheel and the rack, which are in engagement with one another.
  • the circumferential speed u of the vane wheel FR and the speed v3 of the piece goods carriers ST must also be matched to one another such that the horizontal components of these speeds are the same and the illustrated assignment of the circumferential division t2 of the cells Z in the circumferential area to the division t3 the general cargo carrier ST is retained. It can also be seen from FIG.
  • the impeller FR is equipped with fixedly arranged additional vanes ZF, which each form empty cells LZ with the wing F lagging in the direction of rotation DR, which are assigned to the above-mentioned gaps L2 between two groups of piece goods carriers ST.
  • the gaps L2 or the empty cells LZ must be taken into account by increasing the division distance tl by a corresponding compensation amount ⁇ t after four tasks.
  • the piece goods S are transported directly into the cells Z of the impeller FR via the first conveyor FEI.
  • This transport into the rotating impeller FR is made possible by segmenting the impeller FR and the first conveyor FEI, for the explanation of which reference is also made to FIG. 3.
  • the individual vanes F When segmenting the vane wheel FR rotating on a shaft W, the individual vanes F have a plurality of gaps L1 arranged one behind the other in the direction of the wheel axis RA. In the area of these gaps L1, deflection wheels, designated UR, are rotatably arranged on the shaft W, around which the segments of the first conveyor, designated SGI, are guided.
  • the endlessly circulating segments SGI which are formed, for example, by flat belts, are guided via tensioning roller SR and deflection rollers URO1 and UR02.
  • the individual segments of the further conveying device FEW indicated in FIG. 1 only by a dash-dotted line are also guided over these deflecting rollers URO1 and UR02.
  • a common motor M drives via a first drive wheel AR1, a belt indicated by dash-dotted lines RI1 and a wheel RD on the shaft W (compare FIG. 3) of the wing wheel FR.
  • the motor M drives the idler pulley URO1 via belts RI2 shown in broken lines, which in turn drives the tensioning roller SR via another belt RI3 shown in broken lines.
  • This " drive via the common motor M ensures on the one hand that the first conveyor FEI and the further conveyor FEW are always driven at the same speed v1, while on the other hand it also ensures that the ratio of this speed vl to the peripheral speed u or the angular velocity of the impeller FR is always maintained.
  • the guidance of the further conveying device FEW which is divided into segments SG2, over the two deflecting rollers URO1 and UR02 enables a smooth transfer of the piece goods S (compare FIG. 1) to the first conveying device FEI. It is particularly advantageous that the transverse collisions of the segments SG2, which are not shown in the drawing but are required to maintain the spacing t1 (see FIG. 1), dive downward from the common conveying plane of the conveying devices FEI and FEW. This immersion of the transverse tunnels prevents them from compressing the piece goods S (see FIG. 1) into the cells Z of the vane wheel FR and possibly damaging them in the process.
  • the pitch tl + ⁇ t is 510 mm.
  • the impeller FR rotating at 20.8 revolutions per minute has sixteen cells Z and four empty cells LZ.
  • the circumferential pitch t2 of the impeller FR is approximately 127 mm.
  • the segmentation of impeller FR and first conveying device FEI indicated in FIG. 3 comprises a total of ten segments of the impeller of the FR and nine segments SGI of the first conveyor FEI.

Abstract

Le dispositif de transmission comporte une roue à ailettes (FR) dont les ailes (F) sont de préférence des cellules (Z) qui reçoivent le colis de détail (S) arrivant sur un premier transporteur (RE1) et le transmettent aux supports de colis de détail rotatif (ST) d'un second transporteur (FE2). La vitesse (v1) et l'écart (t1) séparant les colis de détail (S) arrivant, la vitesse périphérique (u) et la division circonférentielle (t2) de la roue à ailettes (RF) et la vitesse (v3) et la division (t3) du support de colis de détail (ST) rotatif doivent être harmonisés. Les colis de détail (S) peuvent être transportés directement dans les cellules (Z) de la roue à ailettes (FR) car les ailes (F) possèdent plusieurs trous disposés en long dans le sens axial et les segments du premier transporteur (FE1) sont dirigés dans la roue à ailettes (FR), dans la zone des trous. Le transfert du colis de détail (S) aux cellules (Z) est ainsi contrôlable en toute fiabilité étant donné que l'invention permet de dispenser d'une livraison en fonction de la forme et du poids du colis de détail.
