Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The core of the present invention is to provide a folding tray device for transporting sterilization trays, which can realize the rapid folding and handling of sterilization trays.

[0032] It should be noted that the orientation or positional relationship indicated by "up", "down", "front", "back", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0033] A folding tray device for transporting sterilization trays provided by the present application includes: a frame welded part 1, a four-way shuttle car 2, a telescopic fork assembly 3, a lifting assembly 4 and a conveyor assembly 5;

[0034] Among them, the frame welded part 1 includes a base and two vertically extending substrates, and the two substrates are arranged in parallel;

[0035] The four-way shuttle car 2 is arranged between the upper surface of the base and the two substrates. The four-way shuttle car 2 can slide on the frame welded part 1 and is used to support and transport the sterilization tray 8;

[0036] The telescopic fork assembly 3 is arranged on the frame welded part 1 and can slide vertically along the frame welded part 1. The telescopic fork assembly 3 is used to drive the sterilization tray 8 to move in the vertical direction;

[0037] The lifting assembly 4 is arranged on the frame welded part 1 and is fixedly connected to the telescopic fork assembly 3. The lifting assembly 4 is used to drive the telescopic fork assembly 3 to slide in the vertical direction;

[0038] The conveyor assembly 5 is arranged on the frame welded part 1 and is used to transport the sterilization tray 8 to a designated position.

[0039] Specifically, please refer to the appendix Figure 1 With the appendix Figure 2, the four-way shuttle 2 transports the sterilization trays 8 to the upper surface of the conveying assembly 5. The conveying assembly 5 is arranged directly below the telescopic fork assembly 3. The lifting assembly 4 drives the telescopic fork assembly 3 to move in the vertical direction. After the sterilization trays 8 are placed on the surface of the conveying assembly 5, the lifting assembly 4 drives the telescopic fork assembly 3 to move downward until the telescopic fork assembly 3 is located between the bottommost sterilization tray 8 and the second sterilization tray 8 from the bottom up. After the telescopic fork assembly 3 is clamped with the sterilization tray 8, it is driven upward by the lifting assembly 4, so that only the bottommost sterilization tray 8 remains. The bottommost sterilization tray 8 is driven by the conveying assembly 5 and transported to the next station. After the sterilization tray 8 is transported away, the lifting assembly 4 drives the telescopic fork assembly 3 to descend, so that the bottoms of the remaining multiple layers of sterilization trays 8 fall onto the surface of the conveying assembly 5, and the lifting assembly 4 and the conveying assembly 5 are controlled to move between the currently bottommost sterilization tray 8 and the second sterilization tray 8 from the bottom up at present, lift the sterilization trays 8 except the currently bottommost sterilization tray 8, and the conveying assembly 5 moves the currently bottommost sterilization tray 8 to the next station and repeats the above steps, which can quickly and continuously realize the splitting and transportation of the sterilization trays 8, improve the splitting and transportation efficiency, and the equipment is adapted to the four-way shuttle 2. For the stacking process of the sterilization trays 8, the logic is opposite to the above splitting process. After a single sterilization tray 8 arrives, the multiple sterilization trays 8 inserted by the telescopic fork assembly 3 descend as a whole. After contacting the single sterilization tray 8 that has arrived, the telescopic fork assembly 3 retracts. At this time, the telescopic fork assembly 3 continues to descend, inserts the bottommost sterilization tray 8, rises to a high position, and repeats the above actions in sequence until the whole vehicle is stacked. At this time, the fork descends and the fork is retracted at the conveying position. At this time, the entire sterilization vehicle is transported to the next station.

[0040] On the basis of the above embodiments, a control system is further included. The four-way shuttle 2 includes drive wheels, a jacking mechanism 2-1, a drive assembly and a code scanning and positioning mechanism. The drive assembly is used to drive the drive wheels to rotate. The jacking mechanism 2-1 is used to jack up the sterilization tray 8 to a specified position. The code scanning and positioning mechanism is used to identify the identification mark on the frame weldment 1 and send an electrical signal to the control system. The control system is used to control the opening or closing of the drive assembly.

[0041] Specifically, please refer to the appendix Figure 4 With the appendix Figure 5The driving assembly of the four-way shuttle 2 is used to provide power for the movement of the four-way shuttle 2. The driving wheels include transverse driving wheels and longitudinal driving wheels. An identification mark is set on the frame weldment 1. When the four-way shuttle 2 moves to the specified position, the code scanning and positioning mechanism can identify the identification mark and send a signal to the control system. The control system controls the opening or closing of the jacking mechanism 2-1 and the driving assembly. Generally speaking, the jacking mechanism 2-1 adopts a hydraulic cylinder. The sterilization tray 8 on the four-way shuttle 2 is lifted by the jacking mechanism 2-1 and is transported from the initial position to the specified position. After the code scanning and positioning mechanism sends a signal to the control system, the control system controls the jacking mechanism 2-1 of the four-way shuttle 2 to descend, so that the sterilization tray 8 falls on the surface of the conveying assembly 5, and a certain distance is maintained between the jacking mechanism 2-1 and the lower bottom surface of the sterilization tray 8. The control system controls the lifting assembly 4 and the conveying assembly 5 to perform the above-mentioned splitting steps, and controls the conveying assembly 5 to transport the sterilization tray 8 at the bottom layer to the next station.

[0042] Optionally, the lifting mechanism 2-1 can adopt various combinations such as ball screw lift and guide shaft, cylinder and guide shaft, cylinder and scissor fork, oil cylinder and scissor fork, servo motor and scissor fork, etc., and the lifting mechanism 2-1 can realize the vertical movement of the sterilization tray 8.

[0043] Optionally, the identification mark may be a positioning code, or RFID chip scanning and positioning may be selected.

[0044] On the basis of the above-mentioned embodiment, a four-way shuttle guide rail 6 is further provided on the frame weldment 1 , and the four-way shuttle guide rail 6 is used to limit the movement route of the four-way shuttle 2 .

[0045] For details, please refer to the attached Figure 3 A four-way shuttle guide rail 6 is also provided on the base surface of the frame weldment 1. The four-way shuttle guide rail 6 includes a sub-rail and a main rail, which are used to limit the movement route of the four-way shuttle 2 to ensure that the sterilization tray 8 can be transported to the designated location.

[0046] On the basis of the above-mentioned embodiment, a guide rail safety limit assembly is provided at the end of the four-way shuttle guide rail 6 , and the guide rail safety limit assembly is used to prevent the four-way shuttle 2 from escaping from the four-way shuttle guide rail 6 .

[0047] Specifically, a guide rail safety limit assembly is provided at the end of the four-way shuttle guide rail 6. When the four-way shuttle 2 moves to the guide rail safety limit assembly, the driving wheel will stop rotating due to resistance, preventing the four-way shuttle 2 from colliding with the special aircraft equipment and causing a malfunction due to the loss of the limit number.

[0048] In some embodiments, the conveying assembly 5 includes a roller drive assembly, a driving motor, a transmission shaft, and a transmission sprocket. There are multiple pairs of roller drive assemblies, and the multiple pairs of roller drive assemblies operate synchronously through the transmission shaft and the transmission sprocket. The driving motor is used to drive the roller drive assembly to drive the sterilization tray 8 to move.

[0049] Specifically, the two conveying assemblies 5 operate synchronously through the transmission shaft and the transmission sprocket, and the two conveying assemblies 5 are respectively used to support both ends of the sterilization tray 8. The two conveying assemblies 5 rotate synchronously to ensure the stability of the sterilization tray 8 during transportation.

The output end of the driving servo motor is connected to the ball screw, and the fixed seat is fixedly connected to the moving end of the ball screw. When the driving servo motor is in the on state, it is used to drive the threaded rod of the ball screw to rotate, so that the moving end reciprocates along the guide shaft.

[0051] Specifically, selecting a ball screw as the main body of the lifting assembly 4 can ensure the accuracy, efficiency, and reversibility of the positioning of the lifting assembly 4.

[0052] In some embodiments, the telescopic fork assembly 3 includes a cylinder, a fork, and a guide wheel. The fork is fixedly connected to the output end of the cylinder, and the guide wheel is fixedly connected to the cylinder and is used to limit the movement trajectory of the cylinder.

[0053] Specifically, the telescopic fork assembly 3 further includes a fork seat and a guide sleeve. The fork moves within the guide sleeve. The guide wheel plays a role in strengthening the supporting force of the fork, reducing the radial shear force of the cylinder. The cylinder is connected to the aforementioned control system. When the lifting assembly 4 descends until the sterilization tray 8 lands on the upper surface of the conveying assembly 5, the control system controls the cylinder to retract the fork. After the lifting assembly 4 rises to between the first and second sterilization trays 8 from bottom to top, the control system controls the cylinder to extend the fork. This process is completed by the control system to avoid leaving scratches on the sterilization tray 8.

[0054] Based on the above embodiments, there are four telescopic fork assemblies 3, and the four telescopic fork assemblies 3 are used in cooperation to realize the lifting and lowering of the sterilization tray 8.

[0055] Specifically, the bottom of the sterilization tray 8 is provided with a fork position that is used in conjunction with the telescopic fork assembly 3. The four telescopic fork assemblies 3 are arranged corresponding to the conveying assembly 5, and two telescopic fork assemblies 3 are arranged corresponding to the upper part of each conveying assembly 5. It is necessary to use the four telescopic fork assemblies 3 in cooperation to realize the stable lifting of the sterilization tray 8.

[0056] Based on the above embodiments, there is also a water receiving tray 7. There are two water receiving trays 7, and the two water receiving trays 7 are respectively arranged at the bottom of the frame weldment 1 and the bottom of the conveying assembly 5.
