Definitions

  • the invention relates to a device for the transport of flat products, such as mailing bags, parcels, printed products or workpieces, each of which is fed by a feeder to an inlet opening arranged above the feeder and which is attached to a driven traction means of a conveying device.
  • Such devices are also used as distribution conveyors at the post office or at warehouses, where the products flowing to a collection point are to be distributed to remote locations. Not least because of their different contents, these flat products have, among other things, uneven external shapes and rigidity, which place high demands on machine processing.
  • Devices of the type described at the beginning are, for example used in post offices to sort mailers according to their mailing addresses.
  • the mailing bags are fed to a feeder after recording the shipping address, which hands the mailing bags over to the transport containers, which are assigned to a specific delivery point in a controlled manner.
  • EP-A-0 638 501 discloses a device of the same type for the further transport of individually supplied flat products, in which the transport containers have an upward entry opening for the products conveyed by a feeder.
  • the object of the invention is therefore to provide a device of the type mentioned at the beginning with which the products reach the transport containers in the correct position on the loading path.
  • this object is achieved in that above the conveying device there is provided a guiding arrangement formed in the same direction as the conveying direction and approximately parallel to the inlet openings of the transport containers, penetrating the trajectory of the products and consisting of a plurality of guiding members attached to an endlessly rotating traction member is.
  • the guide members are designed in a funnel-like manner in the direction of movement of the products, so that the initially wide guide means that the products reach the guide members safely and can be set to a narrow trajectory on the subsequent path.
  • the guide members are fastened to the traction member after the regular intervals of the following transport containers and are driven in synchronism with the transport containers, as a result of which no special coordination is required to match the guide members and transport containers at the transfer point.
  • the transfer path at the transfer point can be optimized or lengthened by an opposite inclination of the transport containers to the conveying direction of the conveying device.
  • the traction means to which the transport containers are fastened, is preferably formed by laterally spaced conveyor chains, which run endlessly around deflection rollers.
  • Transport chains are particularly suitable for fastening the guide elements through their side walls on the running axes of the chain links.
  • a further improvement in operational safety and a simplification compared to the known transport containers can be achieved in that the transport containers are closed on all sides and have a flap or slide-like cover at the inlet opening.
  • downstream end of the chute at least approximately abuts the inner wall of the transport container rearward in the conveying direction.
  • a lateral transport chain guide extending over this area can be provided.
  • FIG. 1 shows a conveyor device 1 which has transport containers 3 fastened to a traction means formed from endlessly rotating conveyor chains 2. This is provided at its upper end facing a feeder 4 with an inlet opening 5 through which a flat product 6 is conveyed or falls from the feeder 4 into the transport container 3.
  • the products 6 are mailing bags, parcels, printed products or workpieces that are distributed from one collection point to different, distant locations, storage or work places, or transported to other collection points.
  • the transport containers 3, which are attached to the traction means at regular intervals, have an inclined position counter to the conveying direction F of the conveying device 1 (to the rear), so that the length of the loading path of a transport container in the conveying direction F can be optimized despite the compact arrangement.
  • a proposed feeder 4 which passes the incoming products 6 to the conveyor device 1 in time with the latter of a linear conveyor 7 engaging in a flat frictional engagement on the one main surface of the products 6 for transferring the products 6 to the transport containers 3 and a conveyor rotor 8 driven about an axis perpendicular to the conveying direction of the linear conveyor 7, which rotatably engages with a rolling area of its peripheral surface during transfer rolls on the other main surface of a product 6.
  • the feeder 4 is driven by a motor 9, which is connected by a gear 10 to a conveyor belt designed as a linear conveyor 7 and the conveyor rotor 8.
  • a pretensioning device 11 ensures the correct contact pressure of the conveyor rotor 8 on the product 6 (to be read in the CH patent application No. 2501/95).
  • the present device provides a guide arrangement 12 which laterally limits the conveying path of the products 6.
  • This guide arrangement 12 consists of a pulling member 13 which is driven above the transport container 3 in the same direction as the direction of conveyance F of the conveying device, formed from two parallel transport chains 14, on which individual guide members 15 are arranged at a distance from the transport containers 3 fastened to the traction means of the conveying device 1, which guide the Trajectory resp. enforce the conveyance route of a product 6.
  • Conveyor chains 2 and transport chains 14 each have parallel runs which form a transfer section in one section.
  • the guide members 15 are funnel-shaped and aligned with the trajectory of a product 6, ie the access opening 16 has an extension, viewed in the direction of conveyance F, opposite the inlet opening 5 of the transport container 3, which facilitates the grasping of the products 6 and, through the subsequent tapering, makes the trajectory of a product 6 more precise.
  • the guide member 15 is provided at the downstream end with a guide surface 18 designed as a slide.
  • the partially dissolved funnel shape of the guide member 15 is approximately restored due to the lid opening in this area through the lid 17.
  • a sliding cover would make these arrangements avoidable.
  • the position of the guide surface 18 on the guide member 15 is selected such that the downstream end of the chute is in contact with the inner wall 19 of the transport container 3 rearward in the conveying direction F, in any case does not form a disruptive step or the inlet opening 5 of the transport container 3 is disadvantageous downsized.
  • FIG. 2 shows the funnel-shaped guide member 15 in the loading position. It is fastened in each case by a connecting rod 20 in one pivot axis 21 and in the other pivot axis 22 of a chain link 23, so that the transport chains 14 are not restricted in terms of the mobility of their chain links.
  • a bar 25 is provided on the side walls 24 of the guide member 15.
  • 5 to 7 illustrate the formation of a transport container 3 in the emptying position.
  • 5 shows the still closed transport container 3, which has changed its position by approximately 180 ° with respect to the loading position.
  • the product 6 is now near the lid and leaves the transport container 3 as soon as the lid 17 is opened (see FIG. 6).
  • the cover 17 is held in place by a locking device 26, the bolt 27 of which is lifted out of the lock at the right time by an unlocking device 28 according to FIG. 7.
  • the pivoting of the lid 17 to open a transport container 3 is carried out by a torsion spring (not shown).
  • the cover 17 is closed again against the force of the torsion spring.
