Definitions

  • the object of the present invention is to create a track with catches activated by the work pieces in which the weight of the catch is independent of the weight of the rolling piece end where there is always only one piece in position at the end of the track.
  • a similar switching device is positioned before the end of the track and shuts off the impelling mechanism of the preceding catch if the end of the track is occupied.
  • the switching devices are connected in such a way as to shut off the impelling mechanism of their own catch if their position is unoccupied.
  • FIG. 1 shows a schematic side view of a preferred form of roller track with catches accordingto the invention
  • FIG. 2 a schematic front view of the roller track with catches according to F IG. 1
  • FIG. 3 a schematic diagram of a fluid circuit for actuating the catches according to FIG. 1 and 2.
  • the numeral 1 indicates the two longitudinal support beams inclined in the direction of rolling of the workpieces, such as crankshafts 6, while the support posts are indicated by numeral 2, and numeral 3 the bases of the support posts.
  • the bases 3 are connected with each other by cross pieces 14, and the posts 2 by transverse members 4.
  • a stop 5 At the lower end of the track on the beams l is positioned a stop 5.
  • the workpieces 6 roll downward from left to right in FIG. 1.
  • Each catch consists of two angle levers which are attached to the opposite ends of a shaft 8 between the beams l and pivotal on this shaft 8.
  • each angle lever points obliquely upward opposite to the rolling direction of the workpieces and its free end juts into the roller runway of the workpieces 6.
  • the workpieces 6 roll down to the free end of the longer arm 7 of one of the catches and are stopped there until the angle lever 7 is turned downward.
  • the actuator acts on the shorter arm 12 of the angle lever.
  • a tension spring 9 urges the arm 12 downward and, consequently, the free end of the arm 7 upward into the roller track, and a fluid working cylinder and piston 10, when activated, moves arm 12 upward, simultaneously turning the free end of arm 12, which abuts against the piston rod of cylinder 10.
  • Cylinder 10 is controlled by a fluid circuit means, shown in FIG.
  • FIG. 3 which includes switching valves 13 which are positioned inside the roller track shortly before each catch. and are activated by the workpieces 6. Multiple valves serve as switching devices 13.
  • FIG. 3 a diagram for a roller track with catches according to FIG. 1 and 2 is furnished.
  • V is the switching device associated with the first catch and Z, the pneumatic cylinder actuator for the first catch.
  • Switching device V, and working cylinder Z are associated with the second catch, switching valve V and cylinder Z with the third catch, switching valve V and working cylinder Z, with the fourth catch and switching valve V is associated with the limit stop 5.
  • the third and fourth catch as well as the limit stop 5 are shown as being occupied by a workpiece.
  • the fluid which may be compressed air, flows from a source (not shown) through the pressure regulating device 15 to the connection S of each valve.
  • the valves V and V are shown in the non-activated position wherein the valve bodies having transverse bores indicated by the double-ended arrows are shown in their raised positions while valves V V and V are shown in their activated positions wherein their respective valve bodies are in their lowered positions as a result of presence of a workpiece at the respective catches with which the valves are associated.
  • the fluid from the pressure regulator 15 flows into the activated valves V V and V, from the connection S to connection A of the same valve and from there to connection R of the next following valve.
  • connection R connection R of the same valve and from there to the working cylinder of the preceding catch, activating this cylinder and, at the same time, turning the arm 7 of the catch lever (which juts into the roller track) downward.
  • the work piece 6 then rolls down to the next catch.
  • a valve is activated the flow between connections R and B is cut off by the valve body and the flow between connection B and the opening to the atmosphere for outgoing air P of the same valve is effected. As soon as a valve is activated no more compressed air flows to the working cylinder of the preceding catches. At the same time the cylinder is connected with the opening for outgoing air P.
