Description

Technical Field

[0001] This utility model relates to a positioning and rotating structure for a freeze-dried food transfer rack. Background Technology

[0002] Due to their high hygroscopicity, freeze-dried foods are highly susceptible to moisture absorption and spoilage in exposed environments. Currently, the handling and positioning of carts and pallets for transporting freeze-dried foods are mostly done manually. This manual activity poses risks of contamination from dust and microorganisms. Furthermore, since the freeze-drying cycle is generally long (usually ten to several tens of hours), relying on manual loading and unloading can become a bottleneck in production. Therefore, automated transport of carts and pallets is gradually becoming a future market trend. As the core technology for automated transport of freeze-dried foods, the automatic positioning and rotating mechanism of carts not only affects the rapid and accurate loading and unloading of pallets but also restricts the operating efficiency and overall capacity of automated production lines.

[0003] Most of the newly emerging rack positioning and rotating structures on the market are driven by ordinary motors, and rack positioning largely relies on lifting methods. This can lead to inaccurate positioning when the rack is manually pushed in, resulting in collisions and product spillage, causing losses, downtime, and increased non-productive time. Therefore, a positioning and rotating structure for a freeze-dried food transfer rack is proposed to address the above problems. Utility Model Content

[0019] Specifically, the top rotating mechanism 2, the top positioning mechanism 4, and the drive mechanism 6 are installed on the suspended steel beam of the trolley guide rail, while the bottom positioning mechanism 3, the lifting mechanism 5, and the guide structure 7 are all installed on the bottom rotating platform 1. During production, the trolley 8 is pushed to the bottom rotating platform 1 by manual labor or a conveyor line through the guide structure 7. The bottom rotating platform 1 is designed with a trolley 8 arrival detection function. After confirming that the trolley 8 is in place, it automatically positions and lifts the trolley 8 to the designed height, and gives the system a loading / unloading start signal to start loading and unloading the pallet.

[0029] Specifically, the steering rail 202, top rotating gear 206, top detection mechanism 204, top buffer baffle 205, and upper rail plate 207 are all installed on the gear base plate 206. The gear base plate 206 is suspended below the fixed frame 201 by the lifting rod 208. During production, the top roller of the carriage 8 is transported forward along the steering rail 202. The end of the steering rail 202 is equipped with a top buffer baffle 205 to reduce rigid impact. After the bottom rotating platform 1 confirms that the carriage 8 is in place, the drive mechanism 6 rotates the top rotating gear 203 installed on the gear base plate 206. The steering rail 202 is connected to the top rotating gear 203 through the upper rail plate 207. The steering rail 202 drives the carriage 8 to turn.
