The in-place limit block 406 is fixed at the front of the middle of the conveying frame 405. The two cooperate to firmly fix the grate 7 and prevent it from falling when the grate is flipped over. The main frame limit rod 409 is fixed in the middle of the four vertical beams of the flip-over grate main frame 411. It is mainly used to trigger the travel switch fixed on the truss main frame 302 when the limit sensor of the truss linear module 304 fails, playing a secondary limit role to prevent the equipment from causing more serious failures due to sensor failure. Specifically, the positioning fork mechanism 403 includes a cylinder and a fork plate connected to the cylinder.

[0054] like Figure 1 、 Figure 2 As shown, in an embodiment of the present invention, the control cabinet 6 is installed on the side of the main frame 101 of the destacking main frame 1, and is used to provide power cables to the destacking main frame 1, the walking truss 3, and the flipping and inverting grate mechanism 4; the grate 7 can be effectively transported on the conveying roller line 206 of the lifting and conveying platform 2 and the conveying mechanism 407 of the flipping and inverting grate mechanism 4. At the same time, with the cooperation of the destacking main frame 1 and the lifting and conveying platform 2, the automatic destacking of multi-layer grates 7 and the automatic stacking of single-layer grates 7 are realized; the operation touch screen 8 is fixed on the junction box 108 of the main frame 101, which is consistent with the human operating height, so as to facilitate personnel operation.

[0055] The present invention provides a flip grate device for automatic loading and unloading, and its working principle is as follows:

[0056] After passing through the previous process, the conveyor belt automatically transports the entire stack of grates to the lifting and conveying platform 2 inside the depalletizing and stacking main frame 1. When it approaches the depalletizing and stacking main frame 1, the tilted grates 7 will be automatically guided to the center under the action of the feeding guide seat 107; when the grates 7 trigger the sensor at the entrance of the lifting and conveying platform, the cylinders in the front two groups of cylinder clamping mechanisms 209 drive the clamping rods to extend upward, the conveying roller line 206 runs, and the grates 7 are transported smoothly; when the in-place sensor 207 is triggered, the conveying roller line 206 stops running, and the cylinders in the rear two groups of cylinder clamping mechanisms 209 drive the clamping rods to extend upward, clamping the grates 7 on the lifting and conveying platform 2. Under the action of the lifting drive motor 103, the lifting and conveying platform 2 slowly rises to the designated position, and the cylinder of the rotary positioning mechanism 112 extends to clamp the second layer and above grates in the air, and the first layer of grates is transported to the conveyor belt of the flip-up grate mechanism 4 on the walking truss 3, completing the automatic unstacking of the grates 7. According to the actual use on site, the flip-up grate position can be appropriately adjusted. Under the joint action of the positioning fork mechanism 403 and the in-place limit block 406, the platform flip-up grate does not fall, and the material in the grate can be dumped. The flip-up grate adopts a double-station design, and the same dumping work can be performed on the upper and lower sides, greatly improving the production efficiency of the equipment. The adaptive measuring device 5 installed on the truss main frame 302 can detect the height of the dumped material in real time; when the material reaches the designated height, the equipment stops dumping the material, and the dumped grates are then transported to the lifting and conveying platform 2 through the conveying mechanism 407 of the flip-up grate mechanism 4. The same principle as destacking, the grates are stacked layer by layer under the joint action of the front and rear cylinder clamping mechanisms and the centering and alignment mechanisms. Finally, the whole stack of grates is transported to the conveyor belt of the next workstation, finally realizing the automatic transportation, destacking, flipping, stacking and output of the grates.

[0057] The present invention provides an automatic loading and unloading flip-over grate device that enables automatic loading and unloading of grates, pallet removal, flipping and inverting, conveying, and adaptive measurement. This significantly improves work efficiency, reduces labor intensity, and effectively saves working time. Because the device is constructed entirely of stainless steel and can withstand harsh working environments such as humidity and splashing water, it is gaining popularity among companies in the food industry.

[0058] The above description is only an embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modification, equivalent replacement, improvement, expansion, etc. made within the spirit and principle of the present invention are included in the scope of protection of the present invention.
