Definitions

  • the invention relates to a transport device according to the Preamble of claim 1. It is for Objects such as those stacked together Layers, e.g. Formed stacks of paper or the like are provided.
  • Such stacks o Transport route be continuously movable, or the transport route should be interrupted or shortened in this way, that the respective stack does not cover the entire transport route moved, but beforehand from the transport route is removed.
  • Transport route is one out of two or more transport sections provided by existing carriers, whose two transport sections are mutually transverse or parallel to the transport level or to the transport direction are movable. Both transport sections can also be transporting in the retracted position or a continuous but shortened carrier form and instead of transversely directed transport devices have a common direction of transport.
  • EP-A-0 382 913 which corresponds to the preamble of claim 1, shows a facility with a about the One-piece width and length of the transport sections Transfer belt, which especially in the extended Condition is very difficult to spread evenly over its area is to be kept under tension.
  • FR-A-1 558 053 has one to a discharge exit subsequent transporter on which sheet layers immediately on a stacking table and such a great length has that several leaf layers lying one behind the other on him fit at the same time.
  • the invention has for its object a transport device to create what disadvantages the described type or known training are avoided and that is a very good thing, especially with simple training secure support of the stacks or the like transversely to the transport level ensure in the area of the subsection if this is extended.
  • each Stack in the area of the extended section against resilient movements transverse to and against the Support the transport level essentially rigid.
  • the support closes when the section is extended directly to the front end of the remaining section on.
  • the support member essentially forms one continuous table surface that then between neighboring Forms a cover or shield for transport runners, so that through the gap between adjacent transport runners no objects, dirt or the like can pass through can. Because the respective transport runner with its back essentially over its entire width and / or length can be supported over a large area on the support member he also did not put under particularly high tensile stress but could sag after being released by the support organ.
  • the support member could be independent of the subsection or in a movement deviating from its movement in and be transferable apart from the support layer, but it is useful arranged fixed to the section or stored so that it is in any position of the section compared to this occupies the position described.
  • the support member can essentially be part of its extension congruent to the remaining section z. B. lie in that a support member of the remaining section and a support member of the section at least partially in each position overlap each other. Instead of on the front or top the support member of the section is appropriate the back of the support member of the remaining section.
  • the support member of the remaining section can be in any position of the subsection a continuation of the support member form.
  • the support member of the remaining section with regard to its limitations, as with the support organ of the section described, arranged or formed be.
  • the ejection exit is in proportion large distance from the entrance of those following the carrier Processing facility, namely at a distance that so as large as or larger than the extent of a stack o.
  • the discharge exit very close to the entrance of the processing device arranged, namely at a distance of which, less than the extension of ten, five, three or a stack in the direction of transport so that Between the discharge exit and the entrance of the processing device at most one of a size Number of stacks can be located.
  • Have the exit and the Entrance transverse to the direction of transport essentially one common boundary edge, so after opening the No more stacks at the exit of the processing device are fed but in the processing facility if applicable, there is only the batch that is being processed the fault has occurred.
  • the transport device 1 can, possibly up to the transport runner, one self-contained and with a frame form a foundation or the like to be arranged between neighboring facilities so that your transporter 2 from a feeding transporter 3 one preceding device is loaded and the to be transported Stack to a leading conveyor 4 delivers.
  • All transporters 2 to 4 can approximately in one common transport level 10, or in view of the Transport level 10 and / or a continuous side view have approximately linear common transport direction 5.
  • in the Cross section transverse to the transport direction 5 can the transport plane be inclined to one side or roughly horizontal lie.
  • the conveyors 2 to 4 are instead of approximately vertical here arranged so that the stack under their weight concern them.
  • the transporter 2 has two mutually adjoining in the transport direction 5 Transport sections, namely a front, shortenable section 7 and a rear remaining section 8, which is a fixed longitudinal part of the longest transport route 6 forms, the two transport sections 7, 8 form can.
  • the section 7 is in the position according to FIG. 1 shown in the retracted position so that it is a in the transport level through opening or a Exit 9 forms through which the stacks to the complete Leaving the transport level at right angles to the return or Get to the bottom of the transport route and collect it there or transversely to the conveying direction 5 and approximately parallel to the conveying plane 10 can be promoted.
  • This exit 9 is at its rear end from the front End 11 of the withdrawn section 7 limited and can have a length that is approximately equal to the length of the Stack or smaller.
  • the length of the remaining section 8 is greater than the length of a stack, so that e.g. B. three or four spaced one behind the other Stack lie simultaneously on the transport section 8 can.
  • the length of the extended section 7 is in contrast, smaller or only slightly larger than that Length of a stack, so that on the section 7 in the Usually only one batch is running.
  • the transport width 18 the transport sections 7, 8 is chosen so that in both Directions only one stack at a time.
