  • Patent number: 10450143
    Abstract: A transport system includes a plurality of transport vehicles. Each transport vehicle includes: a distance detecting portion configured to detect a distance to a preceding transport vehicle, which is another transport vehicle traveling in front of the corresponding transport vehicle; a signal transmitting portion for transmitting a start signal to a subsequent transport vehicle, which is another transport vehicle traveling behind the corresponding transport vehicle; and a signal receiving portion for receiving the start signal that is transmitted from the preceding transport vehicle. Each transport vehicle is configured to transmit, when starting to travel, the start signal using the signal transmitting portion, to start to travel upon receiving the start signal from the preceding transport vehicle using the signal receiving portion, and to stop when the distance to the preceding transport vehicle that is detected by the distance detecting portion is equal to or smaller than a set distance.

  • Patent number: 10431485
    Abstract: Before a moving member that moves along a moving path stops, an article transport facility starts protrusion control by which a moving support portion that is provided on the moving member is moved so as to protrude toward a fixed support portion, and thereafter the article transport facility appropriately determines whether or not to continue the protrusion control. Upon the moving member reaching a protrusion start position, the protrusion control is started so that the moving support portion is moved to protrude, even if the moving member has not stopped. After the moving member has reached a position at which a detection unit that is fixed to the moving member can detect a detection target member that is provided on the fixed support portion, the execution of the protrusion control is continued as long as the detection unit is detecting the detection target member.

  • Patent number: 10370224
    Abstract: A flat storage facility includes a storage/retrieval device having a Y-direction moving member with a length corresponding to the width of a storage item placement plane in an X direction and that is movable in a forward/backward Y direction of the storage item placement plane. A carriage is supported on the Y-direction moving member and is movable in the X direction. A storage item gripping mechanism is supported on the carriage so as to be freely raised and lowered. Lowering of the storage item gripping mechanism is controlled such that downward flexural deformation distances between end portions of the Y-direction moving member in the X direction are determined. Lowering distance adjustment values of the storage item gripping mechanism for the storage item placement points are set based on the downward flexural deformation distances, and lowering distances of the storage item gripping mechanism are reduced by the lowering distance adjustment values.
