[0033] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] The object of the present invention is to provide a container cargo loading system, which can remove the pallet and transfer the cargo to the container through the cooperation of the three units of the cargo loading unit, the fixed pushing unit and the mobile pushing unit. The following are specific embodiments:

[0035] The present invention provides a container cargo loading system, comprising a loading unit, a fixed pushing unit and a mobile pushing unit. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 shown.

[0036] The fixed pushing unit 2 is located on one side of the mobile pushing unit 3, and the object carrying unit 1 is located on one side of the fixed pushing unit 2. Figure 1 As shown, Figure 2 , Figure 3 , Figure 4 The loading unit 1 pushes the pallet 4 and the goods to the fixed pushing unit 2 ( Figure 1 In order to facilitate display and make it easier to understand, the goods on the pallet are omitted), the fixed pushing unit 2 pushes the goods to the mobile pushing unit 3, and the pallet 4 is left in the fixed pushing unit 2; the mobile pushing unit 3 transports the goods to the container 5 and pushes the goods off the mobile pushing unit 3, completing the process of loading the goods into the container 5.

[0037] The object-carrying unit 1 includes a first lifting and adjusting bracket 1-1 and a screw translation device, such as Figure 3 As shown. The screw translation device is arranged on the first lifting and adjusting bracket 1-1. The screw translation device includes a screw 1-2 and a push block 1-3. Preferably, the screw 1-2 is an electric screw. The screw 1-2 is arranged in the first lifting and adjusting bracket 1-1 through a bearing, and the screw 1-2 is sleeved with a translation nut 1-4, and the translation nut 1-4 is connected to the push block 1-3, and the push block 1-3 is arranged above the first lifting and adjusting bracket 1-1. The forklift inserts the pallet 4 and the goods on the pallet 4 to place the pallet 4 on the loading unit 1. The translation nut drives the push block 1-3 to push the pallet 4 and the goods to the fixed pushing unit 2.

[0038] The fixed pushing unit 2 includes a second lifting and adjusting bracket 2-1, a tray loading device and a first ejector 2-3. Figure 5 , Figure 6 As shown. One side of the second lifting and adjusting bracket 2-1 is close to the mobile pushing unit 3, and the other side is provided with a support frame 2-5. A first ejector 2-3 is provided on one side of the support frame 2-5, and a tray device is provided on the other side. The ejector is a device commonly used on a forklift to push out goods. In the present invention, a scissor-type hydraulic translation device is adopted, including a scissor-type structure and an oil cylinder. The two ends of the oil cylinder are respectively connected to the two ends of the scissor-type structure, so that the oil cylinder can drive the scissor-type structure to extend or retract, and the principle is equivalent to that of a scissor-type hydraulic lift. The height of the lower edge of the first ejector 2-3 is higher than the sum of the heights of the second lifting and adjusting bracket 2-1 and the pallet 4. A movable baffle 2-6 is provided at the lower end of the side wall of the first ejector 2-3 close to the support frame 2-5 through a fixed collar. The movable baffle 2-6 extends out of the first ejector 2-3 by a certain distance, as shown Figure 7 As shown. When the first ejector 2-3 pushes the goods, the movable baffle 2-6 will bend upward around the fixed ring, so it will not move with the tray 4. After the first ejector 2-3 pushes the goods to the mobile pushing unit 3, during the process of the first ejector 2-3 retracting, the side wall of the first ejector 2-3 blocks the movable baffle 2-6, so the movable baffle 2-6 will move with the tray 4 and push the tray 4 onto the tray loading device.

[0039] The tray loading device includes two hydraulic cylinders 2-4 and a carrier plate 2-7. The hydraulic cylinder 2-4 is inverted on the support frame 2-5. The carrier plate 2-7 is a plate body used to hold the tray 4, and its two ends are respectively connected to the telescopic rods of the two hydraulic cylinders 2-4. When there is no tray 4, the height of the carrier plate 2-7 is flush with the top surface of the second lifting and adjusting bracket 2-1, and the first ejector 2-3 will push the tray 4 onto the carrier plate 2-7 when it retracts. The tray 4 falls on the carrier plate 2-7, and under the gravity of the tray 4 and the carrier plate 2-7, the telescopic rod of the hydraulic cylinder 2-4 is stretched, driving the tray 4 and the carrier plate 2-7 to move down one end distance and find balance again. Preferably, a suitable hydraulic cylinder 2-4 is selected so that the descending distance is equal to the length of the tray 4. An alarm device can also be set on the tray loading device, which can be a weight alarm device or a height alarm device. After the weight carried by the carrier plate 2-7 reaches the set value, an alarm is triggered to prevent the hydraulic cylinder 2-4 from overtravel. In order to ensure that the movable baffle 2-6 can be better driven onto the tray loading device, a plurality of rollers 2-2 are arranged on the second lifting and adjusting bracket 2-1 to further reduce the friction between the tray 4 and the second lifting and adjusting bracket 2-1. The rollers 2-2 are arranged along the direction of the first ejector 2-3 to push out and retract.

[0040] The mobile push unit 3 is a unit for pushing the goods into the container. The mobile push unit 3 includes a third lifting and adjusting bracket, a telescopic arm 3-1 and a mobile forklift. Figure 8 As shown. The telescopic arm 3-1 and the mobile forklift are both arranged on the third lifting and adjusting bracket. A first lifting and adjusting device is arranged on the third lifting and adjusting bracket. The telescopic arm 3-1 includes a fixed body and a mobile body. One end of the fixed body of the telescopic arm 3-1 is hinged on the third lifting and adjusting bracket, and the other end of the fixed body is hinged to the telescopic end of the first lifting and adjusting device arranged on the third lifting and adjusting bracket. The mobile forklift is connected to the mobile body of the telescopic arm 3-1. Preferably, the telescopic arm 3-1 is a four-section telescopic arm, and one end of the fixed body extending out of the mobile body is hinged to the telescopic end of the first lifting and adjusting device.

[0041] The mobile forklift includes a vehicle body 3-2, a movable frame 3-3, a second lifting and adjusting device 3-4 and an L-shaped cargo board 3-5. The movable frame 3-3 is hinged on the vehicle body 3-2. Preferably, the lower end of the movable frame 3-3 is hinged on the vehicle body 3-2, and the upper end is hinged on the vehicle body 3-2 through another hydraulic cylinder 2-4, so that the angle of the movable frame 3-3 can be adjusted by the hydraulic cylinder 2-4. The L-shaped cargo board 3-5 is arranged at the telescopic end of the second lifting and adjusting device 3-4. The oil pump assembly that drives the telescopic arm 3-1 to move can also be arranged on the vehicle body 3-2. A second pusher is arranged on the L-shaped cargo board 3-5. After the fixed pushing unit 2 pushes the goods onto the L-shaped cargo board 3-5, the second lifting and adjusting device 3-4 adjusts the height of the goods according to the height of the container 5. After the adjustment is completed, the movable body of the telescopic arm 3-1 is extended, and the mobile forklift enters the container 5. After reaching the position where it needs to be put down, the second pusher works to push the goods into the position specified by the container 5.

[0042] In the present invention, the lifting and adjusting device used may be an oil cylinder, or other devices capable of achieving a lifting function, such as a gas cylinder, etc., but is not limited thereto.

[0043] Before implementation, the heights of the first lifting and adjusting bracket 1-1, the second lifting and adjusting bracket 2-1 and the third lifting and adjusting bracket are adjusted. The height of the third lifting and adjusting bracket is level with that of the container 5, so that it is convenient for a mobile forklift to enter the container 5. The heights of the first lifting and adjusting bracket 1-1 and the second lifting and adjusting bracket 2-1 are level. The height of the third lifting and adjusting bracket is higher than that of the second lifting and adjusting bracket 2-1. In this way, the goods can be conveniently transferred between the units.

[0044] The forklift places the pallet 4 carrying the goods on the loading unit 1, the screw rod moves, and the push block 1-3 pushes the goods to the fixed pushing unit 2. The first ejector 2-2 of the fixed pushing unit 2 pushes the goods to the mobile pushing unit 3, and leaves the pallet 4 on the second lifting and adjusting bracket 2-1. During the retraction of the first ejector 2-3, the movable baffle 2-6 drives the pallet 4 to be pushed onto the tray loading device, and the tray loading device stacks and collects the pallets 4 one by one. At the same time, the second lifting and adjusting device 3-4 adjusts the height of the goods, and then the telescopic arm 3-1 drives the mobile forklift to enter the container 5. After reaching the designated position, the second ejector pushes the goods off the L-shaped cargo board 3-5. The second ejector retracts. The telescopic arm 3-1 returns to its original position.

[0045] The present invention can also set a manipulator 6 and a cargo support 7 next to the mobile push unit 3. The manipulator 6 can be used to adjust the state and position of the cargo placed on the L-shaped cargo board 3-5. If the amount of cargo stacked is too high, the manipulator 6 can remove some of the cargo and place it on the cargo support 7, or add the cargo placed on the cargo support 7 to the L-shaped cargo board 3-5 so that the cargo can enter the container 5 more smoothly. The manipulator 6 can also adjust the position of the cargo and the angle of entry into the container to ensure that the cargo enters the container 5 conveniently.

[0046] The present invention provides a loading method of a container cargo loading system, comprising the following steps:

[0047] S1: Move the pallet with goods to the loading unit by forklift;

[0048] S2: The loading unit transfers the pallet and the goods to the fixed pushing unit;

[0049] S3: The fixed push unit transfers the goods to the mobile push unit, leaving the pallets behind and stacking them together;

[0050] S4: The mobile pushing unit adjusts the cargo according to the position and height of the container, pushes the cargo into the container, and unloads it.

[0051] The loading unit can smoothly transfer the pallet and the goods to the fixed pushing unit through the screw translation device. The height of the second lifting and adjusting bracket is greater than that of the third lifting and adjusting bracket, so that when the first ejector pushes the goods to the mobile pushing unit, the pallet is left on the second lifting and adjusting bracket. When the first ejector is retracted, the movable baffle under the first ejector blocks the pallet from being pushed toward the tray loading device.

[0052] The tray loading device uses a hydraulic cylinder. The tray loading device adjusts the hydraulic pressure according to the weight of the tray. The tray loading device drops a certain distance each time a tray is added.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
