Title: Material transfer control device for saddle chain conveyor
Inventor: GOTO MASATO
IPC: B65G47/52
Filed: 1985-04-24
Abstract: PURPOSE:To allow transfer operation to be positively accomplished by configurating a device in such a way that the saddle suspension position of an upstream conveyor is detected at the transfer site so as to determine the saddle suspension position of a downstream conveyor in a conveyor as referred to the titled in a hot strip equipment. CONSTITUTION:When a saddle 3 of an upstream saddle conveyor 1 arrives at the transfer site, the saddle 3 is detected by a detector 6. And the time starts being counted until the conveyor 1 is suspended after the saddle 3 has been detected by a detector 5 at the loading site of the upstream conveyor 1 allowing the distance that the conveyor 1 has moved during the period of the time, to be computed. In addition, the difference in distance between the saddle detector 6 which is set in advance, and a suspension position detector 14 of a downstream conveyor 11 is determined. On the basis of this difference determined, the distance moved of the downstream conveyor 11 after the saddle 13 of the downstream conveyor has been detected 14, is controlled. This configuration allows the suspension position for both the upstream and downstream conveyors to correspond with each other permitting transfer operation to be positively accomplished.
