<p>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 which have been stopped on the rods into their neutral initial position on the rods. The rods are mounted radially on a wheel rotating in vertical plane supported by a body and on the body on its side facing the rods there are fitted grooves having the shape of the perimeter of a circle and arranged one upon the other. Along the grooves the slides or beads on the rods are guided to move, and dropping of the slides to be positioned opposite to desired groove is arranged to take place most appropriately at the highest point of the device, where the grooves are cut so as to enable the slides to be dropped.</p> |
