Definitions

  • Mueller ABSTRACT Selector device, in particular a compartment selector device in a log sorter, having rods moving synchronously with the sorting conveyor and connected at both ends with adjacent rods, and on each rod slides movable in their longitudinal direction, means for stopping the slide set into motion with the aid of gravity by dropping it from the upper end of the rod at desired point on the rod, means for further transfer of the pulse transmitted by the slide to triggering, counting or other elements by electrical means, said elements being placeable at desired points on the path of the rods, and controls arranged to move the slides WhlCh have been stopped on the rods into their neutral initial position on the rods.
  • the present invention relates to a selector device, in particular a compartment selector device suited for use in log sorters.
  • the rods have been mounted radially on a wheel rotating in vertical plane supported by a body.
  • the slides or beads on the rods are guided to move and dropping of the slides to be positioned opposite to desired groove has been arranged to take place advantageously at the highest point of the grooves, where they have been cut in order to enable the slides to be dropped.
  • the object of the invention is to accomplish a simple, little space requiring and reliably operating mechanical electrical selector device which by virtue of its simple design will be considerably less expensive to manufacture than electrical and mechanical electrical selector devices in present use.
  • FIG. 1 shows in part a selector device according to the invention, as seen from the side of the spoke wheel,
  • FIG. 2 is the section along the line II in FIG. 1,
  • FIG. 3 is the section along the line IIII in FIG. 1,
  • FIG. 4 is the section along the line IIIIII in FIG. 2, and
  • FIG. 5 is the section along the line IV-IV in FIG. 2.
  • the principal components of the selector device are: 1, body, immovably mounted in vertical plane and having on one side a number of concentric groove tracks 5 and one ascending track 6,
  • spoke wheel the shaft of which has been joumaled in the center of the groove tracks 5 and which rotates in step with the conveyor the operation of which this selector device has been installed to control.
  • the spoke wheel has radial, round spokes 8 on which there is a bead 9, which is free to move axially on the spoke and also in the groove tracks 5,
  • limit switches which have been placed in connection with the groove tracks 5 so that the bead moving in the groove track touches the limit switch on passing it.
  • the holders of limit switches 11 have been mounted on the body so that they can be positioned with reference to the groove track as operations require,
  • flap elements which have been placed on the side opposite to the groove track side on the body 1 in the upper part of the body, at the bead-dropping point 13, from where the beads are set free with the aid of the flap element 14 to drop along the spoke and are stopped opposite to the desired groove track by action of the flap element 15, one of which has been placed opposite to each groove track.
  • the flap elements are most easily actuated by means of an electromagnet.
  • the flap l5 opposite to the groove track corresponding to said point is closed and flap 14 is opened, whereby the bead marking the object to be transported can move along the spoke up to the flap that is in closed position, and the bead is switched to travel in its groove track, which at a given point has a limit switch 3 on touching which the bead initiates e.g., transfer of the object to be transported from the conveyor to another conveyor, or equivalent. Subsequently, the bead arrives on the ascending track 6 and is ready for another control operation.
  • the device shown at 17 is equipment for correction of wrong commands.
  • the selector device In its simplest form, the selector device must in its body have at least as many groove tracks as there are action stations on the length of the conveyor, and the number of beads 9 must at least equal that of objects being transported simultaneously on the conveyor at any given time. In the interest of smaller size of the selector device it is possible to add on every spoke e.g., one (or several) beads 10 and for these beads two groove tracks 7 on the body and on each limit switch holder ll a limit switch 12.
  • the flap element 16 is employed to direct the additional head 10 into one groove track or the other, whereby the switching capacity of the conveyor memory is doubled.
  • the flap elements 15 are most appropriately divided in re gard to their actuating elements on either side of the dropping point 13, although in the interest of lucidity of the drawing all these elements have not been shown in the drawing. Likewise, the limit switch holders 11 have not been shown in the drawings.
  • An improved compartment selector device in a log sorter in which rods are moving synchronously with a sorting conveyor and connected at both ends with adjacent rods, on each rod slides are movable in the longitudinal direction of the rods, means are provided for stopping the slide set into motion due to gravity by dropping it from the upper end of the rod at a desired point on the rod, electrical means are provided for further transfer of a pulse transmitted by the slide to elements placed at desired points on the path of the rods, and controls are arranged to move the slides which have been stopped on the rods into their neutral initial position on the rods, wherein the improvement comprises:
  • a body having on one side facing the rods a plurality of concentric grooves having the shape of the perimeter of a circle;
