Method for handling loads in a warehouse for containers, particularly standard containers
View Patent ↗A method is provided for handling loads in a warehouse for containers that may be automatically stored and removed from storage by a container stacking crane, between a storage area and a truck or other vehicle parked in a parking space of a loading and unloading area To optimize the throughput performance and safety of handling loads in a warehouse for containers, it is proposed that after the truck drives into the parking space and after the driver of the truck leaves the parking space, the parking space is secured against the presence of persons including the driver, before a release signal is given to the container stacking crane for the automatic loading or unloading process.
1. A method for handling loads in a warehouse for containers, said method comprising:
automatically placing the containers into storage and removing the containers from storage with a container stacking crane;
unloading the containers in a loading and unloading area adjacent the warehouse with the container stacking crane;
determining a number of persons, including a driver, positioned in a truck configured for receiving and hauling at least one of the containers when the truck is in a control area;
positioning the truck in a parking space of the loading and unloading area;
vacating the truck and the parking space by the driver;
detecting the departure of the driver from the parking space;
generating an authorization signal and transmitting the signal to the container stacking crane in response to said detecting;
initiating, in response to the authorization signal, an automatic loading or unloading process for transferring the containers onto or off of the truck in the parking space with the container stacking crane;
wherein when said determining the number of persons positioned in the truck in the control area results in a determination that one or more persons, in addition to the driver, are positioned in the truck in the control area; and
relocating the one or more additional persons from the truck to a passenger waiting area so that only the driver remains in the truck for said positioning the truck in the parking space.
2. The method as claimed in claim 1 , wherein the control area includes the passenger waiting area.
3. The method as claimed in claim 1 , further comprising:
relocating the driver from the truck to a driver waiting area after the driver vacates the parking space;
detecting the presence of the driver in the driver waiting area; and
maintaining the authorization signal to the container stacking crane for the loading or unloading process as long as the presence of the driver is detected in the driver waiting area.
4. The method as claimed in claim 3 , wherein the passenger waiting area and the driver waiting area are in different locations.
5. The method as claimed in claim 1 , further comprising securing the parking space against access by persons after the truck has entered the parking space and after the driver of the truck has left the parking space.
6. The method as claimed in claim 5 , further comprising:
completing the loading or unloading process;
informing the driver that the loading or unloading process is completed;
unsecuring the parking space to permit access to the parking space by persons; and
withdrawing the authorization signal to the container stacking crane for the automatic loading or unloading process.
7. The method as claimed in claim 6 , wherein said securing the parking space comprises closing a gate.
8. The method as claimed in claim 7 , wherein the gate is part of a demarcation surrounding the parking space.
9. The method as claimed in claim 5 , wherein said securing the parking space comprises closing a gate.
10. The method as claimed in claim 9 , wherein the gate is part of a demarcation surrounding the parking space.
11. The method as claimed in claim 2 , further comprising:
relocating the driver from the truck to a driver waiting area after the driver vacates the parking space;
detecting the presence of the driver in the driver waiting area; and
maintaining the authorization signal to the container stacking crane for the loading or unloading process as long as the presence of the driver is detected in the driver waiting area.
12. The method as claimed in claim 11 , further comprising:
completing the loading or unloading process;
informing the driver that the loading or unloading process is completed;
unsecuring the parking space to permit access to the parking space by persons; and
withdrawing the authorization signal to the container stacking crane for the automatic loading or unloading process.
13. The method as claimed in claim 11 , wherein the passenger waiting area and the driver waiting area are in different locations.
14. The method as claimed in claim 11 , wherein said securing the parking space comprises closing a gate.
15. The method as claimed in claim 14 , wherein the gate is part of a demarcation surrounding the parking space.
16. The method as claimed in claim 15 , wherein said securing the parking space comprises closing a gate and said unsecuring the parking space comprises opening the gate.
17. The method as claimed in claim 16 , wherein the gate is part of a demarcation surrounding the parking space.
