[0039] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-3 As shown in FIG8 , a silo buffer high-speed discharge structure includes:

[0041] Feeding bin 2;

[0042] lower silo 3; upper silo 2 and lower silo 3 are both formed in a ring shape; upper silo 2 and lower silo 3 are arranged at the same horizontal plane and placed on the same straight line, and upper silo 2 and lower silo 3 are placed above the bracket 6.

[0043] The material taking module 1 is movable in three directions and is placed below the upper silo 2 and the lower silo 3, and is used to transfer the material tray 4;

[0044] Multiple supporting structures 5; at least two supporting structures 5 are installed on the upper material bin 2 and the lower material bin 3, and the supporting structure 5 includes a supporting cylinder 51, a hook plate 52, and a hook block 53. The supporting cylinder 51 is installed on the upper material bin 2 and the lower material bin 3, and the actuating end of the supporting cylinder 51 is connected to the first end of the hook plate 52. The second end of the hook plate 52 is formed with a hook block 53. The upper surface of the hook block 53 is a horizontal plane. When the hook block 53 is retracted, the material tray 4 can move vertically downward in the upper material bin 2 and the lower material bin 3. When the hook block 53 is extended, multiple hook blocks 53 support the material tray 4 placed in the upper material bin 2 and the lower material bin 3 upward.

[0045] like Figure 1-3 As shown in FIG8 , a plurality of slide grooves are provided on the inner walls of the upper hopper 2 and the lower hopper 3. The supporting cylinder 51 is installed on the top of the upper hopper 2 and the lower hopper 3. The hook plate 52 is formed into a Z shape. The hook block 53 can be moved perpendicular to the inner walls of the upper hopper 2 and the lower hopper 3 and placed in the slide groove.

[0046] like Figure 8 As shown, the hook block 53 is arranged close to the bottom of the inner wall of the upper silo 2 and the lower silo 3.

[0047] like Figure 2 and 3As shown, the material taking module 1 includes an X-direction moving mechanism 11, a Y-direction moving mechanism 12, a lifting mechanism 13, and a tray 138. The tray 138 is placed above the lifting mechanism 13, the lifting mechanism 13 is placed above the Y-direction moving mechanism 12, the Y-direction moving mechanism 12 is placed above the X-direction moving mechanism 11, the moving end of the X-direction moving mechanism 11 is connected to the Y-direction moving mechanism 12, the moving end of the Y-direction moving mechanism 12 is connected to the lifting mechanism 13, and the moving end of the lifting mechanism 13 is connected to the tray 138.

[0048] like Figure 4 As shown, the X-axis moving mechanism 11 includes an X-axis base plate 116, an X-axis motor 111, and an X-axis screw assembly. The X-axis base plate 116 and the X-axis motor 111 are fixed in position, and the X-axis screw assembly is installed on the X-axis base plate 116. The active end of the X-axis motor 111 is connected to the input end of the X-axis screw assembly, and the output end of the X-axis screw assembly is connected to the Y-axis moving mechanism 12.

[0049] like Figure 4 As shown, the X-axis screw assembly includes a first X-axis rotating seat 112, a second X-axis rotating seat 113, an X-axis screw rod 114, and an X-axis rotating sleeve 115. The two ends of the X-axis screw rod 114 are rotatably mounted on the first X-axis rotating seat 112 and the second X-axis rotating seat 113, respectively. One end of the X-axis screw rod 114 is connected to the active end of the X-axis motor 111, and the X-axis rotating sleeve 115 is threadedly engaged with the X-axis screw rod 114.

[0050] like Figure 4 As shown, the X-axis moving mechanism 11 also includes two first guide structures, which are arranged parallel to each other and are respectively placed on either side of the X-axis lead screw assembly. The first guide structure includes an X-axis guide rail 117 and an X-axis slider 118. The X-axis guide rail 117 is fixedly mounted on the X-axis base plate 116, and the X-axis slider 118 is fixedly mounted on the Y-axis moving mechanism 12. The X-axis guide rail 117 and the X-axis slider 118 are guided and slidably engaged. The X-axis lead screw 114 is rotatably mounted on the first X-axis rotating seat 112 and the second X-axis rotating seat 113. The X-axis motor 111 drives the X-axis lead screw 114 to rotate. Because the X-axis rotating sleeve 115 engages with the thread of the X-axis lead screw 114 and because of the provision of the first guide structure, when the X-axis motor 111 drives the X-axis lead screw 114 to rotate, the X-axis rotating sleeve 115 moves along the length of the X-axis lead screw 114 and drives the Y-axis moving mechanism 12 to move (in the X direction).

[0051] like Figure 5As shown, the Y-axis moving mechanism 12 includes a Y-axis base plate 121, a Y-axis motor, and a Y-axis screw assembly 122. The X-axis base plate 116 and the Y-axis motor are fixed in position. The Y-axis screw assembly 122 is mounted on the Y-axis base plate 121. The active end of the Y-axis motor is connected to the input end of the Y-axis screw assembly 122, and the output end of the Y-axis screw assembly 122 is connected to the lifting mechanism 13. The structure and working principle of the Y-axis screw assembly 122 are the same as those of the X-axis screw assembly and will not be described in detail here.

[0052] like Figure 5 As shown, the Y-axis moving mechanism 12 also includes a second guide structure, which is parallel to the Y-axis lead screw assembly 122. The second guide structure includes a Y-axis guide rail 124 and a Y-axis slider 123. The Y-axis guide rail 124 is fixedly mounted on the Y-axis base plate 121, and the Y-axis slider 123 is fixedly mounted on the lifting mechanism 13. The Y-axis guide rail 124 and the Y-axis slider 123 slide in a guiding and sliding manner. The Y-axis moving mechanism 12 operates on the same principle as the X-axis moving mechanism 11. When the Y-axis motor drives the Y-axis lead screw to rotate, the Y-axis rotating sleeve moves along the length of the Y-axis lead screw and drives the lifting mechanism 13 to move (in the Y direction). (The Y-axis base plate 121 is connected to the X-axis rotating sleeve 115 and is placed on the X-axis slider 118.)

[0053] like Figure 6 and 7 As shown, the lifting mechanism 13 includes a lifting base plate 131, a lifting motor 132, a gear 133, a rack 134, a lifting block 139, a mounting plate 135, a plurality of guide seats 136, and a plurality of guide rods 137. The lifting motor 132 and the plurality of guide seats 136 are all mounted on the bottom of the lifting base plate 131 (the lifting base plate 131 is connected to the output end of the Y-direction lead screw assembly 122 and is placed on the Y-direction slider 123). The plurality of guide seats 136 are respectively connected to the plurality of guide rods 137. 7 guides, the lower ends of multiple guide rods 137 are connected to the mounting plate 135. The output shaft of the jacking motor 132 and the gear 133, rack 134, and top block 139 are all vertically mounted on the upper part of the mounting plate 135. A hole is provided in the middle of the jacking base plate 131 for the upper end of the top block 139 to pass through. The tray 138 is placed on the jacking base plate 131 so that it can move vertically. After the upper end of the top block 139 passes through the hole, it contacts the bottom of the tray 138, and the gear 133 and rack 134 are meshed. During operation, the jacking motor 132 drives the gear 133 to rotate. Because the gear 133 meshes with the rack 134, the rack 134 moves up and down, driving the entire jacking base plate 131, guide rods 137, and top block 139 to move up and down. When the top block 139 moves upward, it pushes up the tray 138.

[0054] When applying for this job:

[0055] 1. Place the material tray 4 in the upper material bin 2. The hook plate will support the lower edge of the lower material tray 4 under the action of the cylinder.

[0056] 2. After starting the equipment, the bottom reclaiming module 1 runs to the bottom of the loading bin 2.

[0057] 3. The lifting mechanism 13 on the material taking module 1 will rise to the bottom of the bottom material tray 4.

[0058] 4. At this time, the supporting cylinder 51 will retract and release the material tray 4, and then the lifting mechanism 13 will drop to the height of the material tray 4.

[0059] 5. Then the supporting cylinder 51 extends out to support the second tray 4, and then the lifting mechanism 13 drops to zero position, and the self-positioning structure on the material taking module 1 positions and fixes the tray 4, completing a material taking action.

[0060] 6. The material taking module 1 carries the material tray 4 to the middle material taking position to take or put the product until it is completely completed.

[0061] 7. The material taking module 1 drives the material tray 4 to move to the unloading bin 3.

[0062] 8. The lifting structure drives the material tray 4 to rise and automatically unlock. After rising to the supporting position, the supporting cylinder 51 retreats, and then the lifting structure continues to rise to the height of the material tray 4, and then the supporting cylinder 51 extends to support it.

[0063] 9. The lifting structure descends to zero position, completing the unloading tray 4. Then the material taking module 1 moves to the loading bin 2 and the cycle continues.

[0064] In other applications, this application uses a bottom-of-the-bin discharge method and places the three-way reclaiming module at the bottom of the silo. This allows the module to operate at multiple points within the XY travel range of the moving mechanism, allowing it to function as both a tray loading and unloading mechanism and a product loading and unloading platform. Equipped with a fixed-point loading and unloading module, the module drives the tray to move along the XY array, enabling high-speed loading and unloading operations. This method integrates the silo buffering function, tray loading and unloading function, and transfer table loading and unloading functions into a one-stop structural design, making the overall structure compact and occupying minimal space.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
