Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a cargo handling method for a cargo handling vehicle such as an unmanned forklift truck.

Conventional technology When cargo that has been transported by a conventional conveyor or other transport device is loaded onto a cargo handling vehicle such as an unmanned forklift trunk and transported to a warehouse, etc., the cargo is picked up one by one from the transport device and transported. Unfortunately, my work efficiency is poor.

Problems that the invention aims to solve Conventionally, in order to improve work efficiency, a method has been adopted in which cargo is stacked in two layers and transported by a cargo handling vehicle, but this requires the provision of equipment for stacking cargo in two layers. , there were problems such as increased equipment costs.

This invention was made for the purpose of improving the above-mentioned problems.

Means and action for solving the problem: In response to a signal from a transport device such as a conveyor, the fork of the unmanned cargo handling vehicle is inserted into the pallet of the cargo on the transport device, and in this state the cargo is raised to a predetermined height. The fork is raised to wait for the arrival of the next load, and then the fork is lowered in response to the load arrival signal issued by the conveyor, and the load on the fork is stacked in two tiers on top of the load on the conveyor d, and the forks are stacked on top of the load on the upper load pallet. This cargo handling method for an unmanned cargo handling vehicle eliminates the need for double stacking equipment by inserting the extracted fork into the lower loading pallet and then raising the fork to pick up the cargo in a two-tiered state.

EXAMPLE An example of the method of this invention will be described in detail with reference to the drawings. As shown in FIG. 1, the unmanned cargo handling vehicle used in the method of this invention is equipped with a load stabilizer 2 so that the cargo 1 stacked in two levels can be transported in a stable state. To briefly explain this road stabilizer 2, a frame 5 is attached to the front surface of a mast 4 erected at the front of a vehicle body 3α of an unmanned cargo handling vehicle 3 so as to be movable up and down. 6 can be moved up and down by a lift cylinder 7 and a separately provided stabilizer cylinder 8. Further, a stabilizing plate 9 is provided at the top of the frame 5 and projects horizontally forward, and the cargo 1 placed on the fork 6 is held down by the surface of the stabilizing plate 9 from above, thereby transporting the cargo. This is designed to prevent the load 1 from collapsing.

Next, a cargo handling method using the cargo handling vehicle 3 will be explained with reference to FIG.
It waits at the cargo pick-up position on the side of llo and waits for the arrival of cargo 1 (see Figure 2 α).

When the cargo 1 arrives at the pick-up position, the transport device 10 issues an arrival signal, and in response to this, the cargo handling vehicle 3 raises the fork 6 to the height of the pallet I+ as shown in FIG. 2 tbl. Next, the vehicle body 3α moves forward, inserts the tip of the fork 6 into the pallet 11 as shown in FIG. 1 and waits in this state until the next cargo I arrives. When the next load 1 arrives, an arrival signal is issued from the transport device 10 (Fig. 2e), and in response to this, the cargo handling vehicle 3 lowers the fork 6t and places the fork 6 on the load 1' on the transport device 10. Place the upper load 1 as shown in Figure 2 V). After that, as shown in Fig. 2 (gJ), the car body 3α retreats and the fork 6 is pulled out from inside II, and the fork 6 is lowered to the height of the pallet of the cargo 1' on the transport device 10 (second Figure h). In this state, the vehicle body 3α is moved forward again and the tip of the fork 6 is inserted into the pallet 11 of the lower cargo 1' as shown in FIG. 2+i+. When the insertion of the fork 6 is completed, the fork 6 is raised as shown in FIG. The loads 1 and 1' are clamped between the fork 6 and the stabilizer plate 9. In this state, the vehicle body 3α is moved backward, away from the transport device IO, and transported to a facility such as a warehouse (not shown).

In the above embodiment, the cargoes 1 and 1' are transported in two stacks, but by repeating the above operation, it is also possible to pick up cargo in three or more stacks.

Effects of the Invention As described in detail above, this invention enables cargo 1 transported by a conveyor device 10 such as a conveyor to be stacked in two stages and picked up without requiring any two-stage stacking equipment. In addition to reducing the cost of installing two-tiered stacking equipment, it is also possible to load and receive two-tiered cargo without the need for manpower, thereby reducing labor costs.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention, and FIG. 1 is a perspective view of an unmanned cargo handling vehicle, and FIGS. Cargo handling vehicle, 3α is the vehicle body, 6
1 is a fork, 10 is a conveyance device, and 11 is a pallet.

Claims (1)

[Claims] Unmanned cargo handling vehicle 3 receives cargo arrival signal from transport device 10
The fork 6 of the pallet 1 of the load 1 on the conveyor 10
In this state, the cargo 1 is raised to a predetermined height, and then the fork 6 is lowered in response to a cargo arrival signal from the transport device 10, and the cargo 1 on the transport device 10 is lowered.
By placing the load 1 on the fork 6 on top of ', the loads 1 and 1' are stacked in two layers, and in this state, the fork 6 pulled out from the upper load 1 is placed on the pallet 11 of the lower load 1'. A cargo handling method for an unmanned cargo handling vehicle characterized by inserting the cargo into a transport device 10 and picking up the cargo in a two-tiered state.
