The details of the method of use of the ton package material loading equipment in combination with the above are given below:

when the warehouse ton bag material conveying production line operates, the second driving motors 42 on the fixed chain transmission supporting device and the movable chain transmission supporting device of the ton bag conveying device 1 are started, and the chain transmission of the ton bag conveying device 1 operates.

And then, the third driving motor 54 of the traveling structure of the ton bag conveying device 1 is started, so that the ton bag conveying device 1 travels to the outlet of the conveyor, the fixed chain transmission supporting device of the ton bag conveying device 1 is opposite to the outlet of the conveyor, and the preparation working state of the ton bag conveying device 1 is realized.

When the ton package materials of the conveyor are stacked at proper positions on the fixed chain transmission supporting device, the chain transmission of the fixed chain transmission supporting device stops.

The ton bag conveying device moves to enable the movable chain transmission supporting device of the ton bag conveying device to be opposite to the outlet of the conveyor, and when ton bag materials of the conveyor are stacked at a proper position on the movable chain transmission supporting device, the chain transmission of the movable chain transmission supporting device stops.

At this time, the control screw adjusting device 49 of the ton bag conveying device 1 is turned on to reduce the speed of the motor (i.e., the first driving motor), so as to adjust the movable chain transmission supporting device left and right, and further adjust the distance between the ton bag materials on the fixed chain transmission supporting device and the movable chain transmission supporting device to a proper distance, thereby increasing the stability of the ton bag material stacking.

The ton bag transfer device 1 then travels on the transfer rails to the appropriate position directly in front of and below the forks 19 of the forklift truck stacking device 3.

The goods pushing structure 20 of the forklift stacking device 3 is retracted.

The hydraulic system is regulated by operating the control unit 25, the first hydraulic cylinder 8 is lowered at the top with the chain wheel 13, and the chain 9 lowers the working mast together with the fork 19.

When the pallet fork 19 descends to a proper position of the rear upper part of the support frame of the ton bag conveying device 1 and the rear lower part of the ton bag material, the forklift stacking device 3 moves forwards on the loading and unloading guide rail 2 along the guide rail, when the forklift stacking device 3 moves to just cover the pallet fork with the ton bag material, the forklift stacking device 3 stops moving forwards and backwards,

the hydraulic system is controlled to regulate through the operation control unit 25, the chain wheel 13 is driven at the top of the first hydraulic cylinder 8, and the working door frame and the goods shelf are driven to ascend together by the chain 9.

When the forks 19 are raised to a small height to the proper position, the second hydraulic cylinder 22 on the chassis of the truck-stacking apparatus 3 begins to retract, causing the rear wheel 24 to rotate upwardly relative to the chassis frame 18, thereby effecting a rearward tilt of the chassis frame 18 to the working mast of the truck-stacking apparatus 3, causing an upward tilt of the forks 19.

Following forward movement of the forklift stacking device 3 on the loading and unloading rail 2 along the rail, the position sensor 28 senses the delivery to the appropriate location above the truck.

Then, the top of the first hydraulic cylinder 8 is lowered with the chain wheel 13 by adjusting the hydraulic system, and the chain 9 drives the working door frame and the goods shelf to be lowered to the proper position together.

At the same time, the second hydraulic cylinder 22 on the chassis of the forklift stacking device 3 starts to extend, causing the rear wheel 24 to rotate downwards with respect to the chassis frame 18, thereby achieving a forward tilt of the chassis frame 18 carrying the forklift stacking device 3, and a downward tilt of the forks 19.

Subsequently, the forklift stacking device 3 is moved backwards along the loading and unloading rail 2 while pushing the pusher structure 20 of the forklift stacking device 3 open.

After the unloading process of the ton-packed materials is completed, the goods pushing structure 20 of the forklift stacking device 3 is retracted, the chain 9 drives the working gantry and the goods shelf to ascend together through adjusting the hydraulic system, and meanwhile, the forklift stacking device 3 moves backwards on the loading and unloading guide rail 2 along the guide rail.

Subsequently, the second hydraulic cylinder 22 on the chassis of the fork truck stacking apparatus 3 is allowed to retract, so that the chassis frame 18 carries the working mast of the fork truck stacking apparatus 3 with a backward tilt and the forks 19 with an upward tilt until the fork truck stacking apparatus 3 returns to the initial position, wherein the working mast is tilted backward and the forks 19 are tilted upward to be level with the ground.

The ton bag material handling and loading and unloading integration is realized, the scheduling capacity of loading and unloading of a traditional forklift is greatly improved, and the loading and unloading efficiency of the ton bag material is improved to a great extent.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
