Definitions

  • the invention relates to a switching device for suspended conveyors.
  • conveyors are used forming a plurality of loops, each of which is generally connected to a main transport path, in particular by means of referral.
  • these suspended conveyors comprise rails which are carried by a structure and, for example, are connected to a load-bearing element in particular by means of rigid lines.
  • the articulation is of a type with a degree of freedom so that the movable section is really only maintained by said articulation and the trajectory of its free end is defined exclusively by the position of the axis of joint.
  • the front face of the movable section is necessarily sufficiently spaced from the end face of the fixed rail considered to allow the escape of the free end of the movable section from its so-called passage position towards its standby position but, nevertheless sufficiently close to not do not interfere smoothly with the passage of the carriages from one rail to another.
  • this front face of the movable section is not in abutment on the end of the fixed rail but when a load circulates on this section, it inflicts, at this section, a variable bending with the load and, at the axis of articulation, a stress which could cause, if not shearing, at least rapid wear of this articulation by friction and / or a deformation which would adversely affect the proper functioning of the mobile section.
  • the movement of the movable section can be controlled using a motor means, but more generally this is done manually by an attendant.
  • the invention relates to such a switching device, in particular characterized in that the free end of the movable section is supported substantially over its entire trajectory by a suspension element connecting said free end to at least one fulcrum which, located above the plane defined by the trajectory of said mobile section considered, is substantially on the axis of the articulation means of the mobile section so as to form a triangulation.
  • a conveying installation 1 for example, for a garment workshop which, for transferring the garments from one work station to another, comprises a plurality of loops, each being generally connected to a so-called main track 2 by means of switching devices 3.
  • these rails are carried by a structure 4 and, for example, are connected to a carrier element in particular by means of hangers 20.
  • the mobile section can be straight or curved.
  • the articulation 9, 10 is of a type with a degree of freedom so that the movable section is only really maintained by said articulation and its trajectory is defined exclusively by the position of the articulation axis.
  • the rail preferably has an inverted V-shaped section and these are the two branches 12, 13 of the V-shaped which serve as rolling tracks for rolling elements that have carriages (not shown) traveling on the suspended rails.
  • the lines are fixed on the tip of the Vé, for example using a weld bead.
  • the front face of the movable section is necessarily spaced from the end face of the fixed rail considered to allow the escape of the free end of the movable section from its so-called passage position towards its standby position even if this difference remains small in order to do not interfere smoothly with the passage of the carriages (not shown) from one rail to another.
  • the end face 21 of the movable section is orthogonal to the longitudinal axis 22 of the section considered, the latter is inclined on this axis from the tip of the Vé towards the rear of the movable section in the manner of a bias cut and the end face 23 of the fixed rail is also inclined on its axis to obviously remain parallel to the end face 21 of the movable section.
  • the axis of rotation 24 of the movable section 5, 6 adjoins the lateral edge of this movable section substantially at the intersection of the rear face of the movable section and the lateral edge on the side from which the movable section escapes. of the fixed section. This is how the minimum distance between the fixed part and the mobile part is allowed without harming its exhaust.
  • the raceway is therefore practically continuous and the wheels of the carriage pass well from one rail to another.
  • the free end 5b, 6b of the movable section is supported substantially over its entire trajectory by a suspension element 25 connecting said free end 5b, 6b to at least one fulcrum 26 which, located at above the plane defined by the trajectory of said movable section considered, is substantially on the axis 24 of the articulation means 9, 10 of the movable section so as to form a triangulation.
  • the suspension element is of the variable length type along the trajectory of the end of the movable section and its variation is controlled as a function of the position of the movable section along the trajectory.
  • it is an elastic element of predetermined stiffness.
  • the suspension element 25 is of fixed length such as a tie rod.
  • this tie can be deformed to bypass part of the structure.
  • At least one of the ends of the suspension element is associated with one of the parts that are the fulcrum and the movable section by articulation means 27.
  • This means of articulation of the suspension element can be of the type with several degrees of freedom.
  • one 28 of the axes of this articulation means connecting the fulcrum 26 and the suspension element 25 is collinear with the axis 24 of the articulation means of the movable section associating the latter with the fixed part of the structure which supports it.
  • the articulation means 27 of the suspension element 25 and the articulation means 9, 10 of the movable section are located on either side of the portion of structure supporting said movable section, this with respect to a plane which is substantially horizontal.
  • the switching device generally comprises two mobile sections, each of them being connected by a hinge 9, 10 to one of the fixed rails such as the secondary rails.
  • These movable sections are shaped so that the free ends alternately occupy the passage position thus connecting one or the other of the secondary rails with the main rail.
  • the mobile sections are provided with means 19 for synchronized control of their movement.
  • the synchronized control means comprises a link 19 which at least indirectly connects the ends of the movable sections.
  • the assembly which are the two mobile sections and the control means is designed so that one of the mobile sections preferentially occupies one of the singular positions.
  • the assembly includes a return member (not shown).
  • the most usual position of the switch is that in which in particular the movable section which is then curved is lifted and the rail support tube which supports this curved rail is not just vertical to the curved rail but is somewhat shifted.
