Transport system, control method, and non-transitory computer-readable medium comprising control program

A control method of a transport system, the transport system comprising:

• a transport device for transporting a workpiece to be machined;
• a storage, which is one of transport destinations of workpiece by the transport device, capable of storing a plurality of workpieces;
• a work station, which is one of transport destinations of workpiece by the transport device, for a worker to perform work for workpiece;
• a machine tool, which is one of transport destinations of workpiece by the transport device, for machining a workpiece;
• and
• an operation panel capable of receiving designation of a workpiece having priority regarding machining order over other workpiece,
• the control method comprising:
• acquiring weight of a workpiece to be transported from the work station to the storage;
• and
• determining a storage destination inside the storage for the workpiece to be transported based on the weight, the storage destination being determined so as to be closer to the machine tool as the weight increases,
• the control method further comprising:
• executing a processing of determining a storage destination inside the storage regardless of weight of the workpiece having priority, when receiving the designation, the storage destination being a storage location that is still closer to the machine tool among storage locations inside the storage,
• the controller method further comprising:
• acquiring a second weight of a workpiece stored in the storage
• in the determining, when the first weight is heavier than the second weight, the storage destination is determined so as to be closer to the machine tool than the storage location of the stored workpiece, and
• when the first weight is lighter than the second weight, the storage destination is determined so as to be farther from the machine tool than the storage location of the stored workpiece.

A non-transitory computer-readable medium comprising a control program of a transport system, the transport system comprising:

• a transport device for transporting a workpiece to be machined;
• a storage, which is one of transport destinations of workpiece by the transport device, capable of storing a plurality of workpieces;
• a work station, which is one of transport destinations of workpiece by the transport device, for a worker to perform work for workpiece;
• a machine tool, which is one of transport destinations of workpiece by the transport device, for machining a workpiece;
• and
• an operation panel capable of receiving designation of a workpiece having priority regarding machining order over other workpiece,
• the control program causing the transport system to execute:
• acquiring weight of a workpiece to be transported from the work station to the storage;
• and
• determining a storage destination inside the storage for the workpiece to be transported based on the weight, the storage destination being determined so as to be closer to the machine tool as the weight increases,
• the control program further causing the transport system to execute:
• a processing of determining a storage destination inside the storage regardless of weight of the workpiece having priority, when receiving the designation, the storage destination being a storage location that is still closer to the machine tool among storage locations inside the storage,
• the controller program further causing the transport system to execute:
• acquiring a second weight of a workpiece stored in the storage,
• in the determining, when the first weight is heavier than the second weight, the storage destination is determined so as to be closer to the machine tool than the storage location of the stored workpiece, and
• when the first weight is lighter than the second weight, the storage destination is determined so as to be farther from the machine tool than the storage location of the stored workpiece.
