TRANSFERRING MECHANISM FOR AUTOMATIC WAREHOUSE

PURPOSE:To prevent the breakage of a bucket and the failure of a transferring mechanism for the bucket in the bucket transferring mechanism onto a movable truck by detecting the possibility of the contact of a load mounting base to a rail in the load mounting base or a moving base, and in the case of possible contact, stopping a transferring process. CONSTITUTION:Before a bucket 2 is moved from a load mounting base onto a movable truck 6, a detecting device 700 for an abnormal load mounting detects whether the bucket 2 or received articles M have possibility to come into contact or collision with a rail 91 or not. Namely it is judged whether a signal including that light adiated from a luminescent element 701 is received by a light receiving element 702 is sent out or not, and when the light receiving signal is not sent out, the bucket 2 is judged to be in an abnormal state shown by a two-dot chain line to have the possibility of coming into contact with the rail 9. At this time, a control circuit 605 for each truck prohibits the driving of a transferring motor not shown in a drawing for prohibiting the transferring action.
