Description

Pallet supply automation system {AUTOMATION SYSTEM FOR FEEDING PALETTE}

The present invention relates to a system for automatically supplying pallets, and in particular, a sensor unit and a reader unit are installed in pallet racks and workstations to automatically supply pallets to the workstations, and the pallet supply automation can track the position of the pallets. It is about the system.

As technology for computers and networks develops, interest in ubiquitous is increasing. Ubiquitous is an environment where users can freely access the network regardless of the location of the computer or network.

For ubiquitous, the possibility of its utilization is being raised in various fields such as logistics and courier service that interlocks with electronic tags, mobile service, amusement park loss prevention system, medical insurance card service, and airport baggage management system.

Therefore, as a ubiquitous realization method, a user can track and manage the location of air cargo anytime and anywhere through the linkage between the air cargo management system and the mobile communication system.

According to the cargo management system used in the prior art, a bar-code is attached to the air cargo to read the information of the cargo, and to determine the transport route according to manage the air cargo.

Specifically, the air cargo is transferred to a truck dock area by a transport means such as a truck, and safety inspection of the air cargo is performed through a scanning operation such as X-ray. After the safety check, the weight of the air cargo is sensed, and the air cargo is loaded on pallets at the workstation for each destination, and the pallets loaded with cargo are stored and stored in the Elevating Transfer Vehicle (EVT) area. Ship to your destination.

However, the operation of loading pallets by placing pallets in the workstation is performed by the operator directly through a forklift, specifically, after the worker moves the pallets to the workstation through the forklift, The worker who drives the forklift or another worker carries out the work of loading the air cargo on the pallet arranged in the workstation.

Therefore, each time a worker loads a cargo, he or she must not only move the pallet to the workstation by using a forklift, but he also has to carry out both pallet movement and cargo loading. The disadvantage is that it takes. In addition, since the worker who stores the pallet and the worker who moves the pallet are different from each other, there is a disadvantage that the worker who stores the pallet needs to check the inventory of the pallet and fill the inventory. The disadvantage is that it can't be traced.

In addition, when a certain amount of cargo is loaded on the pallet 100a seated on the workstation 170 by the operator, the second sensor unit 120b may load the cargo, that is, load the pallet 100a. A second electrical signal corresponding to the load of the pallet 100b loaded with the cargo is generated and transmitted to the system controller 140.

The configuration of the second sensor unit 120b will be described in more detail together with the system control unit 140.

The third sensor unit 120c is installed on the moving unit 130 to generate a third electrical signal by detecting the presence of the pallet 100a moved by the moving unit 130, and generates the third electrical signal. To the system control unit 140. The system controller 140 determines the position of the pallet 100a that is moving the moving means 130 based on the third electrical signal, and controls the moving means 130 and the sorter 150 to control the pallet 100a. To be seated on the workstation 170.

Preferably, the third sensor unit 120c may be installed at one side of the moving unit 130 as shown in FIG. 2, and more preferably, may be installed to face the second sensor unit 120b. have.

The moving unit 130 receives the pallet 100a selected by the pallet moving arm 113 from the pallet 100a loaded on the pallet rack 110 and moves the pallet 100a to the work station 170.

Preferably, the moving means 130 may have a traveling direction in one direction, as shown in FIG. 2, and may include a conveyor to easily move the heavy weight pallet 100a.

The first reader unit 160a recognizes a tag attached to the pallet 100a loaded on the pallet rack 110. Preferably, as shown in FIG. 3, the first leader 160a may be installed at one lower surface of the pallet rack 110, and more preferably, may be drawn out by the pallet moving arm 113. The tag attached to the pallet 100a supplied to the moving means 130 may be recognized. The first reader unit 160a recognizes a tag attached to the pallet 100a supplied to the moving unit 130, generates cargo tracking information, and transmits the cargo tracking information to the system controller 140.

The second reader unit 160b recognizes a tag attached to the pallet 100a seated on the workstation 170. Preferably, the second reader unit 160b may be disposed at a predetermined interval on one side of the moving unit 130 similarly to the second sensor unit 120b, and moved by the moving unit 130 to be a workstation. The tag attached to the pallet 100a seated at 170 is recognized. The second reader unit 160b recognizes a tag attached to the pallet 100b seated on the workstation 170, generates cargo tracking information, and transmits the cargo tracking information to the system controller 140.

The third reader unit 160c recognizes a tag attached to the pallet 100a moved by the moving unit 130. Preferably, the third reader unit 160c may be installed at one side of the moving unit 130 similarly to the third sensor unit 120c. The third reader unit 160c recognizes a tag attached to the pallet 100a that is moving the moving unit 130, generates cargo tracking information, and transmits the cargo tracking information to the system controller 140.

Since the system controller 140 stores information about pallets and information about cargoes stored in the tag, the cargo generated from the first reader 160a, the second reader 160b, and the third reader 160160c. Upon receiving the tracking information, the system controller 140 may know the positions of the pallets 100a and 100b based on the received cargo tracking information.
