Title: Load bracing control method of winding transporter
Inventor: YOSHIDA AKIRA
IPC: B66C13/22
Filed: 1987-09-17
Abstract: PURPOSE: To prevent the swing of load by setting the required operating times, accelerations, and velocities for each operation as predetermined function values including the suspension lengths of the load which are measured in every fixed period, the angular velocities of suspension angles, and the fixed periods. CONSTITUTION: A crane device 10 in a warehouse 12 moves along a travel rail 16 and a traverse rail 18 in the order of operation from accelerated operation to swing-stopping operation to equal-velocity operation to decelerated operation. The required operating times tu , tt , te and td , accelerations, and velocities Vu-Vd for these operations are set as predetermined function values including the suspension lengths La-Ld of a load 24 which are measured in every fixed period, the angular velocities of suspension angles, and the fixed periods. Thus, even if the load is hoisted up during the accelerated operation and down during the decelerated operation, the load can be conveyed without leaving swing behind in the load at the end of conveying, whereby the total required operating time can greatly be reduced.
