  • Patent number: 11878867
    Abstract: A lifting and lowering transportation device is capable of transporting articles between different delivery positions using transportation units, each including a lifting and lowering platform, a linear motor, and a chain. The lifting and lowering platform can pass through the delivery positions by moving along the circumferential track that is common to the transportation units. The linear motor generates the driving force to move the lifting and lowering platform along the circumferential track. The chain is loop-shaped and can circulate along the circulation track corresponding to the circumference path, and the linear motor moves the lifting and lowering platform by circulating the chain by the driving force generated by the linear motor. The circulation of the chain in each transportation unit is controlled independently of the other transportation units.

  • Patent number: 11882619
    Abstract: A safety signal system includes portable remote controllers and a second receiver to control a stacker crane in accordance with an instruction received wirelessly from the portable remote controllers. For example, one of the portable remote controllers and the second receiver are able to establish a wireless connection by being in a pairing state in which the single second receiver is fixed as a connection partner of the one portable remote controller. After the wireless connection is established, the pairing state is continued in a state where the wireless connection is not able to be maintained before an operation to disconnect the wireless connection is performed. After the wireless connection is not able to be maintained, the wireless connection is re-established on a condition that power of both the one portable remote controller and the second receiver which are in the pairing state is turned on.
