Components 2 having different parameters are sorted into classes of uniform parameter by means of rotating table 1, the component being discharged from the table at an appropriate discharge point. A component 2 of class 5 let us say is placed into a receptacle 3 at station 0 on the table. The operator operates handle 7 to effect a movement of five notches of gear 6. The gear engages rack 8 to cause the respective shaft 5 to be displaced upwards (as shown) by a distance of five units. Table 1 having been thus set, is stepped round. As the table rotates, rack 8 engages stationary cam 9 so that after one step to station 1 shaft 5 has been displaced downwards by one unit. After five steps of rotation by table 1 rack 8 has been displaced five units downwards to its initial position and component 2 occupies station V. At this position abutment 11 carried by shaft 5 strikes a fixed abutment 12 to cause rotation of shaft 5 and therefore of pivoted shutter 4 to release the component from its receptacle 3 to be discharged at station V. A further displacement of table 1 causes abutment 13 to engage fixed stop 14 to bring receptacle 3, shaft 5 and rack 8 back to their original position 0 ready for a further cycle of movement. The table 1, shafts 5 and racks 8 form a memory system which may operate electrically any system of discharge. Alternatively the shafts 5 and racks 8 may be carried by an endless chain in lieu of table 1. Endless belt discharge, Fig. 3 (not shown).- Articles of differing classes may be placed on conveyer 30 and discharged at selected stations by use of the same memory system. As shown, an article is to be discharged from belt 30 at station 3 by plough 34/III. The memory system 33 of the above type has been set by the operator by the rotation of the said gear 6 by three steps by means of the handle. The belt 30 has been started so that with each rotation of the conveyer roller dog 31 moves wheel 32 by one step and after three rotations of the conveyer roller wheel 32 has been moved through three steps at which memory device 33 operates to cause plough 34/III to discharge the article as shown. |
