Abstract

PURPOSE:To enable highly efficient operation of a crane by adding a warehousing sensor on a carry-in conveyer and a function for abandonedly moving the crane by the warehousing sensor into a crane schedule. CONSTITUTION:When a warehousing sensor 6 provided in the midway of a carry-in conveyer 6 on the upstream side from a warehousing station 3 detects a work 4, the sensor instructs preparation for warehousing to a stacker crane 1. That is, if the crane 1 is waiting for warehousing or shipment, the crane 1 starts to move toward the station 3. When the sensor 6 detects the work 4, the crane immediately starts to move to the warehousing station, and the crane arrives at the warehousing station at the same time when the work is ready for being loaded on the warehousing station. Therefore with such timing that the crane starts to move to the warehousing station as the station is ready for loading, permitting warehousing to be done in a shorter time than conventional methods.

An automated warehouse has a large number of racks for storing loads (works),
It consists of a stacker crane that transports loads between the loading and unloading stage 1 and the racks, and a conveyor that transports loads to be stored toward the loading station. When the cargo to be stored arrives at the warehousing stage, the stacker crane is instructed to perform the storage operation. (Unexamined Japanese Patent Publication No. 63-71004@)
[Problems to be Solved by the Invention] The conventional technology did not give consideration to highly efficient crane operation, leaving room for more efficient crane operation.

The warehousing detection sensor is installed on the loading conveyor, and its installation position is on the upstream side where the crane loads cargo. The time from when the warehousing detection sensor detects the load to when the load arrives at the warehousing station and when the crane can load it is constant. This time is set to be the average time required for the crane to move from an arbitrary position to the warehousing stage. When this warehousing detection sensor is activated, the crane immediately starts moving to the warehousing station, and the crane arrives at the warehousing stage and the cargo becomes ready to be loaded onto the warehousing stage at almost the same time. Therefore, warehousing is possible in a shorter time than in the conventional method in which the crane starts moving to the warehousing stage at the timing when the warehousing stage becomes ready for loading.

Figure j11 shows a stacker crane 11 that transports a workpiece 4, a rack 2 that transports the workpiece, a warehousing stage 3 that allows the stacker crane to load from the carry-in conveyor 5, and a warehousing detection sensor 6 that detects the workpiece. The equipment configuration formula is shown. The work 4 stored in the rack 2 passes through the carry-in conveyor 5, becomes ready to be loaded onto the stacker crane 1 at the warehousing stage 3, is loaded onto the stacker crane 1, and is stored in the rack 2. The workpiece 4 is transported to the unloading station 7 in response to a request for unloading the workpiece.

When the warehousing detection sensor 6 provided midway on the carry-in conveyor 5 on the upstream side of the warehousing station 3 detects the work 4, it instructs the stacker crane 1 to prepare for warehousing work. However, if the stacker crane I is waiting for loading/unloading, the stacker crane l starts moving toward the loading station 3.
