Definitions

  • the invention relates to a switch for a overhead conveyor that in the preamble of claim 1 Art.
  • Such a switch is known from DE-PS 30 48 384.
  • the known switch serves to connect one first rail end optionally with a second or a third rail end, each the first Opposite rail end.
  • the switch has two switch tongues.
  • One of the switch tongues is at an angle running axis of rotation with the second rail end and the other switch tongue over a likewise oblique one Rotation axis rotatable with the third rail end connected.
  • the switch tongues can so about the axes of rotation be pivoted that the free ends of the switch tongues alternately with the free end of the first Align the end of the rail in alignment.
  • Both switch tongues are connected to each other via a tie rod and are at a predetermined distance from each other held so that both switch tongues moved synchronously can be.
  • both switch tongues are not only in the move the desired movement synchronously to change the switch, but also when unwanted forces arise one of the switch tongues, for example accidentally a move from the opposite direction to one itself Engagement with the first rail end Turnout tongue retracts. The resulting forces transfer fully to the first switch tongue, which thereby be moved from their aligned position and cause the overhead conveyor train to crash can. Excessively large ones can also act on the bearings Forces cause permanent deformations.
  • the invention is therefore based on the object, the known Switch to develop such that undesirable Loads on the switch tongues are intercepted.
  • the task is characterized by the characteristic features of the Claim 1 solved.
  • the configuration according to the invention allows both Switch tongues under a load below the predetermined spring force is moved synchronously. However, if a force is applied to one of the switch tongues, which is above the predetermined spring force, so this is absorbed by the spring and does not necessarily lead to move the other switch tongue too.
  • the spring force is expediently used according to claim 2 so on the weight of the switch tongues and the modalities the switch conversion matched that both switch tongues moved synchronously when switching the switch become.
  • An embodiment of the invention is as follows based on the single drawing, the one top perspective view of the switch according to the invention shows.
  • the figure shows a switch 1 which is between a first Rail end 2, a second, the first rail end 2 opposite, second rail end 3 and one third rail end 4 is arranged, which is also the first rail end 2 is opposite.
  • the second rail end 3 as straight extension of the first rail end 2 is formed and the third rail end 4 represents a lateral one Branch.
  • All rail ends 2, 3 and 4, as well as the ones on the Connecting rail ends, not shown Rails have a roof-shaped running profile on which Suspended funds, not shown, can run off, the two each by one passing under the rail Brackets have interconnected castors.
  • the rail ends 2, 3 and 4 are evenly distributed Spacer 5 with one above the rail ends 2, 3, 4 arranged support structure 6 connected, the a first tubular support section 6a and one includes second tubular support portion 6b which via a pipe connector 7 at right angles to each other are connected.
  • the first beam section 6a connects the first rail end 2 to the third Rail end 3 in a straight line.
  • the second beam section 6b connects the second rail end 3 with the third rail end 4.
  • the support structure 6 is through a Cross stiffener 6c stiffened by a the spacer 5 is connected to the third rail end 4 is.
  • the support structure 6 is part of the support structure for the entire rail system of the overhead conveyor trained, for example the first Carrier section 6a over the entire length of the rails 2, 3 run, and in the area of the third rail end via a connecting pipe piece 8 with a further support section 9 along the rail of the rail end 4 can be connected.
  • a second, curved switch tongue 12 is in the same Way with an inclined pivot bearing 13 connected to the third rail end 4 that the second Switch tongue 12 with one end aligned with the third rail end 4 remains aligned and the second, free end 12a of the switch tongue 12 from the in the Drawing drawn, ineffective position pivoted into the effective position shown in dashed lines can be in which the free end 12a with the first rail end 12 is aligned.
  • Switch tongues 11, 12 for a joint movement over a spring element in the form of a push rod 14 with each other coupled.
  • the push rod 14 consists of two telescopic against the spring force of one inside the Push rod 14 arranged, not shown compression spring extendable and telescopic parts 14a, 14b.
  • the free ends of the push rod 14 are over each a ball joint 15 (only one drawn) with a lever plate 16 (also only one drawn) swiveling connected.
  • the lever plates 16 are over one of the spacers 5, each with a switch tongue 11, 12 rigidly connected.
  • One of the lever plates 16 engages Actuator 17 to change the switch.
  • the actuator 17 is attached to a carrier plate 18 which is in turn arranged on the supporting structure 6, and actuated via an actuator 19 and a ball joint 20 Lever plate 16.
  • the spring force of the compression spring in the push rod 14 is so on the weight of the willow tongues 11, 12 and the Actuating forces of the switch matched that when actuated of the actuator 17 both switch tongues synchronously be moved and thus the distance of their free ends lla, 12a maintained.
  • the free end 12a the second switch tongues 12 from that in the drawing shown, ineffective position moved to a position in which the free end 12a with the first Rail end 2 is aligned, so that moves at the same time free end lla in the dashed line in the drawing Position without changing their distance from each other changed.
  • the push rod 14 can bias the compression spring the push rod 14, for example via a screw connection be changed in the region of the ball head 15. It is also possible to only push the push rod 14 on one side over a ball joint with the respective Connect switch tongue. Instead of the push rod an exposed compression spring can also be used. At a different position of the axes of rotation of the pivot bearings 10, 13 and a related other direction of movement the switch tongues 11, 12 may be necessary under certain circumstances be one between the two switch tongues Tension rod and a tension spring to be provided.
