Title: Overhead conveyor systems
IPC: B61B10/02
Filed: 1971-07-15
Abstract: 1307944 Conveyer systems V A LIPOVETSKY and M A RIKMAN 5 July 1971 [30 Dec 1970] 31371/71 Heading B7L In an overhead conveyer comprising feeding section 1 and receiving section 2 interconnected by a switch 3, each section provided with a traction member 6 carrying pushers 7, the load trolleys 9 are each provided with a front and a rear depressible pawl, 13, 14 respectively, the front pawl 13 having a wider surface of contact with the pushers 7 than the rear pawl 14, and a depressor arm 19 is situated above the switch to depress the front pawl 13 of a load trolley moving over the feeding section toward the receiving section before the pawl 13 comes into contact with a pusher 7 of the receiving section, said depressor arm 19 being capable of lateral movement so that said trolley moving over the feeding section 1 shifts the arm from the zone of movement 20 of the rear pawl of said trolley to the zone of movement 21 of the front pawl of a trolley on the receiving section 2. The lateral movement of the depressor arm 19 is achieved by rigidly connecting it, via an axle 16 and bearings 17, to a switch blade 15 which moves under the action of guide rollers 11 mounted on the trolleys 9. The depressing of the front pawl 13 ensures that jamming between the pawl and a pusher 7 of the receiving section does not occur when the trolley transfers to the receiving section. As the trolley approaches the receiving section 2 under the action of a feeding section pusher, the guide rollers 11 move the blade 15 and arm 19 towards the receiving section to vacate the feeding track for movement of the trolley and front pawl 13 is depressed by arm 19. Just as the feeding section pusher disengages the trolley the front pawl passes by the arm 19 and returns under the action of a counterweight to its upper position ready for engagement with a receiving section pusher which pushes the trolley along the receiving track. In the case of a trolley moving along the receiving section the blade and link are moved over into the feeding section by the guide rollers 11 thus allowing the trolley to continue moving unimpeded.
