The details of the use method of the above-mentioned ton package material loading equipment are given below:

When the warehouse ton bag material transportation line is running, the fixed chain drive support device and the second drive motor 42 on the movable chain drive support device of the ton bag transportation device 1 are turned on, and the chain drive of the ton bag transportation device 1 is operated.

Then turn on the third drive motor 54 of the walking structure of the ton-bale conveying device 1, so that the ton-bale conveying device 1 walks to the exit of the conveyor, so that the fixed chain drive support device of the ton-bale conveying device 1 is facing the outlet of the conveyor, so as to realize The ready-to-work state of the ton-bale conveying device 1 .

When the ton bag material of the conveyor is stacked in the proper position on the fixed chain drive support device, the chain drive of the fixed chain drive support device stops.

The ton bag conveying device walks so that the movable chain drive supporting device of the ton bag conveying device is facing the outlet of the conveyor. The chain drive of the support device stops.

At this time, the control screw adjustment device 49 of the ton-bale conveying device 1 is turned on to reduce the motor (ie, the first drive motor), so as to realize the left and right adjustment of the movable chain drive support device, and then adjust the fixed chain drive support device and the movable chain drive support device. The distance between the ton bag materials on the chain drive support device is adjusted to an appropriate distance to increase the stability of the ton bag material stacking.

Then, the tonnage conveying device 1 travels on the conveying rail to an appropriate position just in front of the fork 19 of the forklift stacking device 3.

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

By operating the control unit 25 to control the adjustment of the hydraulic system, the top of the first hydraulic cylinder 8 is lowered with the sprocket 13, and the chain 9 lowers the working mast and the fork 19 together.

When the fork 19 descends to a suitable position above the back of the support frame of the ton bag conveying device 1 and the rear and bottom of the ton bag material, the forklift stacking device 3 moves forward along the guide rail on the loading and unloading guide rail 2 until the ton bag material just covers When the fork is loaded, the forklift stacking device 3 stops moving forward and backward,

The adjustment of the hydraulic system is controlled by operating the control unit 25, the first hydraulic cylinder 8 carries the sprocket 13 on the top, and the chain 9 drives the working gantry and the rack to rise together.

When the fork 19 rises to a small height to a proper position, the second hydraulic cylinder 22 on the chassis of the forklift stacking device 3 begins to retract, so that the rear wheel 24 rotates upward relative to the chassis frame 18, thereby realizing the chassis frame 18 The working gantry that drives the forklift stacking device 3 has a backward inclination, so that the fork 19 has an upward inclination.

Then, the forklift stacking device 3 moves forward along the guide rail on the loading and unloading guide rail 2, and is transported to a suitable position above the truck by sensing the position sensor 28.

Afterwards, by adjusting the hydraulic system, the top of the first hydraulic cylinder 8 is lowered with the sprocket 13, and the chain 9 drives the working gantry and the rack to descend to the proper position together.

At the same time, the second hydraulic cylinder 22 on the chassis of the forklift stacking device 3 begins to extend, so that the rear wheel 24 rotates downward relative to the chassis frame 18, so that the chassis frame 18 drives the working door of the forklift stacking device 3 The frame has a forward inclination so that the fork 19 has a downward inclination.

Then, while pushing the cargo pushing structure 20 of the forklift stacking device 3 away, the forklift stacking device 3 is moved backward along the guide rails on the loading and unloading guide rails 2 .

When the unloading process of the ton-packaged materials is completed, while the pushing structure 20 of the forklift stacking device 3 is put away, the chain 9 drives the working gantry and the rack to rise together by adjusting the hydraulic system, and at the same time, the forklift stacking device 3 is loaded and unloaded. The guide rail 2 moves backward along the guide rail.

Then let the second hydraulic cylinder 22 on the chassis of the forklift stacking device 3 begin to shrink, so that the chassis frame 18 drives the working gantry of the forklift stacking device 3 to have a backward inclination, so that the fork 19 has an upward inclination to reach the cargo. The forks 19 are level with the ground until the forklift stacker 3 returns to the original position.

It realizes the integration of ton-package material handling and loading and unloading, which greatly improves the scheduling ability of traditional forklifts for loading and unloading, and greatly improves the loading and unloading efficiency of ton-package materials.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the protection scope of the present invention.
