[0009] Furthermore, the upper support roller is a power roller.

[0010] Furthermore, the lower support roller is an unpowered roller.

[0011] Furthermore, the width of the frame is smaller than the width of the raw material plate.

[0012] Furthermore, the engaging jaw mechanism includes a support connected to the output end of the first lifting mechanism and two L-shaped clamping plates slidably arranged on the support, and also includes a screw drive component that drives the two L-shaped clamping plates to move closer or farther away from each other.

When the transition device moves, the weight of the entire transition roller mechanism and the raw material plates is supported by the lifting plate, which can reduce the burden of the first horizontal linear moving mechanism and ensure the stability and reliability of the raw material plates during transportation at this stage. After the transition device moves the raw material plates to the top of the ton bag, the raw material plates are clamped by the plate unloading device, and finally the transition device retreats, and the plate unloading device places the raw material plates at the bottom of the ton bag. After repeating the above steps, multiple raw material plates can be neatly stacked above the bottom of the ton bag. Finally, after the second lifting mechanism drives the lifting plate to descend, the ton bag is flipped back, and the stacked ton bags are covered to complete the neat bagging of the raw material plates, and finally they are transported by the conveying device.

[0028] The overall structure of the present invention is simple, without expensive manipulator equipment, and only requires some linear moving mechanisms to achieve neat bagging of heavy raw material plates. The raw material plates are handled with care during the entire bagging process, and will not be damaged. There is no need for excessive arrangement of flexible ton bags, which greatly simplifies the complexity and success rate of bagging, improves the degree of automation, and improves the overall transportation efficiency of raw material plates.

[0052] The specific method of using this raw material logistics line is as follows: It includes the following steps:

[0053] S1. Reference Figure 2 , the four corners of the ton bag 7 are clamped and fixed on the ton bag fixing buckle 42;

[0054] S2. Reference Figure 3 The second lifting mechanism 51 drives the lifting plate 52 to rise and lift the ton bag 7 and pass it through the ton bag turning groove 43, so that the ton bag 7 turns over and makes the bottom of the ton bag 7 contact with the lower support roller 223;

[0055] S3. Reference Figure 4 , the first transverse linear moving mechanism 21 drives the transition roller mechanism 22 to approach the end of the raw material plate 6;

[0056] S4. References Figure 4 , the raw material plate conveyor belt 1 conveys the raw material plate 6 until it is conveyed to the upper support roller 222;

[0057] S5. Reference Figure 5 The first transverse linear moving mechanism 21 drives the transition roller mechanism 22 carrying the raw material plate 6 to move to the bottom of the plate unloading device 3. When the transition roller mechanism 22 moves, the lower support roller 223 moves on the bottom of the ton bag 7;

[0058] S6. Reference Figure 6 The first lifting mechanism 31 drives the clamping claw mechanism 32 to clamp the two sides of the raw material plate 6. Figure 7 , the first transverse linear moving mechanism 21 continues to reset and exits the range of the unloading device 3 and the ton bag lifting mechanism 5;

[0059] S7, Reference Figure 8 and Fig. 9 , the first lifting mechanism 31 drives the clamping claw mechanism 32 clamping the raw material plate 6 to descend to the bottom of the ton bag 7, the clamping claw mechanism 32 releases the raw material plate 6, the first lifting mechanism 31 is reset, and then the second lifting mechanism 51 descends a distance equal to the thickness of the raw material plate 6;

[0060] S8, repeat steps S3-S7, refer to Fig.10 , stacking a plurality of raw material plates 6 and placing them on the bottom of a ton bag 7;

[0061] S9. Reference Fig.11 , the second lifting mechanism 51 descends to below the ton bag turning slot 43, the ton bag 7 turns over and resets, and the bottom and outer side of the ton bag 7 wrap the stacked multiple raw material plates 6;

[0062] S10, the conveying device conveys the ton bag 7 containing the multiple raw material plates 6 to the next station.

[0063] The raw material logistics line provided by the present invention fastens the four corners of the bag opening of the ton bag 7, and flips the ton bag 7 through the ton bag lifting mechanism 5, so that the bottom of the ton bag 7 faces upward and is placed at the bottom of the transition device 2. The transition device 2 is used to receive the raw material plate 6 on the raw material plate conveyor belt 1 to the top of the bottom of the ton bag 7.

Finally, after the second lifting mechanism 51 drives the lifting plate 52 to descend, the ton bag 7 flips back and covers the stacked ton bags 7 to complete the neat bagging of the raw material sheets 6. Finally, the conveying device conveys the ton bag 7 containing multiple raw material sheets 6 to the next workstation.

[0064] The overall structure of the present invention is simple, without expensive manipulator equipment, and only requires some linear moving mechanisms to achieve neat bagging of heavy raw material plates 6. The raw material plates 6 are handled with care during the entire bagging process, and will not be damaged. There is no need to excessively organize the flexible ton bags 7, which greatly simplifies the complexity and success rate of bagging and improves the degree of automation. In addition, the present invention is suitable for bagging raw material plates 6 of various shapes and sizes and has strong applicability.

[0065] In one embodiment, the upper support roller 222 is a powered roller, which can drive the raw material sheet 6 to move to the center of a row of upper support rollers 222, so as to facilitate the alignment of the raw material sheet 6 with the overturned ton bag 7 and improve the bagging accuracy.

[0066] In one embodiment, the lower support roller 223 is an unpowered roller, which is mainly used to bear the weight of the transition roller mechanism 22 and the raw material plate 6. The use of an unpowered roller can make the transition roller mechanism 22 move smoothly at the bottom of the ton bag 7, thereby reducing costs.

[0067] In one embodiment, the width of the frame 221 is smaller than the width of the raw material plate 6 , so as to facilitate the subsequent engagement of the clamping jaw mechanism 32 to clamp the raw material plate 6 .

In this embodiment, the two L-shaped clamping plates 322 are driven to move closer or further away from each other by the screw driving component 323, so that the raw material plate 6 can be clamped and placed on the basis of being centered, thereby improving the bagging accuracy on the basis of simple and reliable structure.

[0069] In one embodiment, the axis of the screw drive 323 is parallel to the width direction of the frame 221, that is, the two L-shaped clamping plates 322 are clamped in the width direction of the frame 221, thereby improving the clamping accuracy.

[0070] In one embodiment, the first transverse linear moving mechanism 21, the first lifting mechanism 31 and the second lifting mechanism 51 are hydraulic cylinders. The hydraulic cylinders have a strong load capacity and can be adapted to transport heavier raw material plates 6, thereby improving equipment stability.

[0071] In one embodiment, the conveying device includes a second transverse linear moving mechanism, and the second lifting mechanism 51 is arranged at the output end of the second transverse linear moving mechanism, which can convey the ton bag 7 containing the raw material plate 6 to the next workstation, such as a transport vehicle.
