Abstract

This article describes an improved work station used in an automated guided vehicle system (AGVS) to permit the work flow to proceed more efficiently in one direction. An operator workstation serviced by an AGVS periodically requires an empty pallet to be delivered and a full (loaded) pallet to be removed, or vice versa. A typical operator workstation having a unit load AGVS is a pallet stand as shown in Fig. 1. With this arrangement, the AGVS vehicle normally makes a 90Πturn from the main guide path to deposit or to pick up a pallet from the stand. The operator must then wait for an empty pallet to be delivered. The full pallet is usually removed by one AGVS vehicle, and the empty pallet is brought by another AGVS vehicle. The arrangement being disclosed, shown in Fig. 2, utilizes a two (or more) pallet position stand.

Improved AGVS Work Station

This article describes an improved work station used in an automated guided vehicle system (AGVS) to permit the work flow to proceed more efficiently in one direction. An operator workstation serviced by an AGVS periodically requires an empty pallet to be delivered and a full (loaded) pallet to be removed, or vice versa. A typical operator workstation having a unit load AGVS is a pallet stand as shown in Fig. 1. With this arrangement, the AGVS vehicle normally makes a 90OE turn from the main guide path to deposit or to pick up a pallet from the stand. The operator must then wait for an empty pallet to be delivered. The full pallet is usually removed by one AGVS vehicle, and the empty pallet is brought by another AGVS vehicle. The arrangement being disclosed, shown in Fig. 2, utilizes a two (or more) pallet position stand. When a pallet is full, a command is given to cause the AGVS to pick up an empty pallet from a pallet dispenser and to deliver it to the empty pallet drop-off point on the stand. The AGVS vehicle then moves forward and picks up the full pallet. This arrangement allows the same vehicle to deliver an empty pallet and to pick up a full pallet at the same location, thereby improving vehicle utilization since there is minimal travel in an empty mode between drop-off and pick-up locations. Another version of the disclosed arrangement provides a third pallet position for another empty pallet. An additional advantage is that an...
