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 turned 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, and play a secondary limit role to prevent the equipment from causing more serious failures due to sensor failure. Specifically, the positioning fork-taking mechanism 403 includes a cylinder and a fork-taking plate connected to the cylinder.

[0054] like Figure 1 , Figure 2 As shown, in the embodiment of the present invention, the control cabinet 6 is installed on the side of the main frame 101 of the depalletizing main frame 1, and is used to provide power cables for the depalletizing 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, and at the same time, with the cooperation of the depalletizing main frame 1 and the lifting and conveying platform 2, the automatic depalletizing 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 distribution 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:

[0056] After passing through the conveyor belt of the previous process, the whole stack of grates is automatically conveyed to the lifting and conveying platform 2 inside the main frame 1 for depalletizing and stacking. When it is close to the main frame 1 for depalletizing and stacking, the inclined grates 7 will be automatically guided to be aligned with 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 operates, and the grates 7 are conveyed 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 to clamp 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, the cylinder of the rotating positioning mechanism 112 extends, clamps the second layer and above grates in the air, and the first layer of grates is transported to the conveyor belt of the flipping and inverting grate mechanism 4 on the walking truss 3, completing the automatic unstacking of the grates 7. According to the actual use on site, the flipping and inverting 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 flipping grate does not fall, and the dumping of the material in the grate can be completed. The flipping and inverting grate adopts a double-station design, and the same inverting grate work can be performed on the upper and lower sides, which greatly improves 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 grate is then transported to the lifting and conveying platform 2 through the conveying mechanism 407 of the flipping and inverting grate mechanism 4. The same principle as depalletizing, 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, and finally the whole stack of grates is transported to the conveyor belt of the next workstation, finally realizing the automatic transportation, depalletizing, flipping, stacking and output of the grates.

[0057] The invention provides an automatic loading and unloading flip grate device, which can realize automatic loading and unloading of grates, stacking, flipping and inverting, conveying, adaptive measurement, etc., greatly improving work efficiency, reducing labor intensity, and effectively saving work time. Since the device is made of all stainless steel, it can adapt to harsh working environments such as humidity and splashing water, and is gradually favored by food industry enterprises.

[0058] The above description is only an embodiment of the present invention and is not intended to limit the protection scope 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 protection scope of the present invention.
