Description

Technical Field

[0001] This invention relates to the field of propulsion technology, and in particular to a three-dimensional silkworm rearing production line. Background Technology

[0002] Silkworm rearing requires placing silkworms in silkworm trays (silkworm frames). Currently, several trays are typically stacked and placed in the rearing area. Whenever mulberry leaves need to be added to the trays or they require disinfection, mulberry leaves must be added to each tray individually, and lime powder must be sprinkled on them to feed and disinfect the silkworms. Farmers generally use manual labor to disassemble and arrange the trays one by one for adding mulberry leaves and sprinkling lime powder. After this process, the trays need to be stacked back together. This manual disassembly and stacking of trays is time-consuming and labor-intensive, often requiring multiple people to work together, severely impacting work efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a three-dimensional silkworm rearing production line that enables automatic unpacking and stacking, and allows silkworm frames to be transported one by one via a conveyor belt assembly, enabling manual feeding and disinfection operations to be performed in the conveyor belt assembly area.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A three-dimensional silkworm rearing production line includes the following:

[0006] The silkworm frame stacking and unstacking mechanism includes two lifting components arranged laterally opposite each other, with a certain distance between the two lifting components forming a receiving space for the silkworm frames. Each lifting component includes a stand, a lifting assembly, a moving-point telescopic module, a fixed-point telescopic module, a conveyor belt assembly, and a conveyor telescopic assembly. The conveyor telescopic assembly is mounted on the stand and can move laterally. The conveyor belt assembly is mounted on the conveyor telescopic assembly and can move longitudinally in a cyclic motion, extending into or retracting from the receiving space under the drive of the conveyor telescopic assembly. At least two fixed-point telescopic modules are longitudinally... The fixed-point telescopic modules are arranged at equal height on the upright and can extend or retract laterally to enter or exit the receiving space; the lifting assembly is installed on the upright and can move vertically; at least two movable-point telescopic modules are arranged longitudinally at equal height on the lifting assembly and can extend or retract laterally to enter or retract into the receiving space; the fixed-point telescopic modules are located above the conveyor belt assembly, and the movable-point telescopic modules can move vertically between a position below the conveyor belt assembly and a position above the fixed-point telescopic modules in the vertical plane under the action of the lifting assembly.

[0007] A conveying mechanism includes a frame and a conveyor belt assembly. The conveyor belt assembly is mounted on the frame and is capable of longitudinal cyclic movement. The conveyor belt assembly includes a conveyor belt component and a conveyor drive component. The conveyor belt component is mounted on the frame, and the conveyor drive component is mounted below the conveyor belt component on the frame. The conveyor drive component is drively connected to the conveyor belt component to drive the conveyor belt component to cyclic movement.

[0008] The conveyor belt assembly has a silkworm frame stacking and unstacking mechanism arranged at both ends of its longitudinal direction, and the two ends of the conveyor belt assembly are connected to two conveyor belt assemblies to transport the silkworm frames. The silkworm frame stacking and unstacking mechanism at the beginning of the conveyor belt assembly is used for unstacking the silkworm frames, and the silkworm frame stacking and unstacking mechanism at the end of the conveyor belt assembly is used for stacking the silkworm frames.

[0009] The lifting assembly includes a lifting drive, a lifting platform, and a slide rail assembly. The slide rail assembly extends vertically and is installed on the upright. The two slide rails of the slide rail assembly are respectively arranged at the two longitudinal ends of the upright. The two longitudinal ends of the lifting platform are slidably connected to the two slide rails. A pair of movable telescopic modules are installed on the inner side of the lifting platform. The lifting drive is installed on the upright and can drive the lifting platform to move up and down along the slide rail assembly.

[0010] The telescopic conveyor assembly includes a telescopic push rod and a telescopic guide rail assembly. The two telescopic guide rails of the telescopic guide rail assembly are arranged at the longitudinal ends of the upright frame, respectively, with the fixed ends of the telescopic guide rails installed on the upright frame and the movable ends of the telescopic guide rails installed on the conveyor belt assembly. The movable end of the telescopic push rod is installed on the conveyor belt assembly, and the fixed end of the telescopic push rod is installed on the upright frame. Driven by the telescopic push rod, the conveyor belt assembly can move along the telescopic guide rails to extend into or withdraw from the receiving space.

[0011] The conveyor belt assembly includes a conveyor belt component and a clutch drive component. The clutch drive component includes a fixed-point drive shaft, a moving-point drive shaft, and a separable coupling. The inner axial end of the fixed-point drive shaft is mounted at the inner longitudinal end of the upright frame, and the outer axial end of the moving-point drive shaft extends laterally and connects to the conveyor belt component. The inner axial end of the moving-point drive shaft and the outer axial end of the fixed-point drive shaft are laterally separable connected via the separable coupling, and the moving-point drive shaft can drive the conveyor belt component to circulate under the transmission of the fixed-point drive shaft. The separable coupling includes a fixed-point coupling section and a moving-point coupling section. The fixed-point coupling section is mounted at the outer axial end of the fixed-point drive shaft, and the moving-point coupling section is mounted at the inner axial end of the moving-point drive shaft. The moving-point coupling section and the fixed-point coupling section can laterally approach and engage or separate under the push of the conveyor telescopic assembly. When the fixed-point drive shaft rotates in the forward direction, the outer end face of the fixed-point coupling section is provided with two or more teeth arranged in the forward direction, and the inner end face of the moving-point coupling section is provided with two or more teeth arranged in the reverse direction. The angle between the front end face of the teeth in the forward rotation direction and the circumferential surface is 60°-90°, and the rear end face of the teeth in the forward rotation direction is an inclined surface that gradually convexes axially as it approaches the front end face in the forward rotation direction.

[0012] The conveying drive unit includes a conveyor motor, a conveyor drive shaft, and a synchronous shaft. The conveyor motor is connected to the fixed-point drive shaft via the synchronous shaft. The conveyor drive shaft, driven by the synchronous shaft, drives the conveyor belt to circulate. The conveyor belt and the conveyor conveyor belt can circulate simultaneously under the synchronous shaft drive to convey the silkworm frames, with the circulating speed of the conveyor belt being less than that of the conveyor belt. The conveyor motor is installed in the longitudinal center of the frame and below the conveyor belt. Two synchronous shafts extend laterally and are installed at both ends of the frame's longitudinal direction, also below the conveyor belt. Both synchronous shafts are connected to the conveyor motor, and each synchronous shaft is connected to the fixed-point drive shaft of the silkworm frame stacking / unstacking mechanism on the same side. The inner axial end of the conveyor drive shaft is installed at one longitudinal end of the frame, and the outer axial end extends laterally and connects to the conveyor belt. The conveyor drive shaft is also connected to the synchronous shaft on the same side to drive the conveyor belt to circulate under the synchronous shaft drive.

[0013] As mentioned above, silkworm frame stacking and unstacking mechanisms are arranged at both ends of the longitudinal direction of the conveyor belt assembly. The silkworm frame stacking and unstacking mechanism at the beginning of the conveyor belt assembly is used for unstacking the silkworm frames, and the silkworm frame stacking and unstacking mechanism at the end of the conveyor belt assembly is used for stacking the silkworm frames. Automatic unstacking and stacking can be realized. Moreover, the silkworm frames are transported one by one through the conveyor belt assembly. Manual feeding and disinfection operations can be performed in the area of ​​the conveyor belt assembly, or related equipment can be set up for operation.

[0014] Based on the aforementioned example, as an alternative, to address the issue of synchronous lifting of the two sets of lifting components, this example includes a lifting drive unit comprising a lifting motor, a torque linkage, a steering box, a lifting shaft, and a chain condition. In each lifting component, the steering box is mounted on the upright and positioned longitudinally inside the lifting platform. The chain condition is connected to the lifting platform. The axial ends of the lifting shaft extend longitudinally and are connected to the chain condition and the steering box, respectively, and the lifting shaft can drive the chain condition to circulate, thereby driving the lifting platform to move up and down. The axial ends of the torque linkage extend laterally and are connected to the two steering boxes, respectively. The lifting motor is mounted on an upright and is connected to the torque linkage via a transmission connection. Thus, the lifting motor, through the torque linkage and the steering box, synchronously drives the two sets of lifting components, effectively improving the stability of lifting or lowering the silkworm frame during unstacking and stacking processes.

[0015] Based on the aforementioned example, as an alternative, in order to ensure stable separation and connection of the fixed-point drive shaft and the moving-point drive shaft during operation, the separable coupling in this example further includes an elastic element and a limiting block. The moving-point coupling section is slidably sleeved on the axial inner end of the moving-point drive shaft. An axially extending limiting groove is provided on the outer wall of the axial inner end of the moving-point drive shaft, and an axially extending limiting opening is provided on the inner side wall of the moving-point coupling section. The axial length of the limiting opening is less than that of the limiting groove. The length of the limiting block is adapted to the axial length of the limiting groove. The recessed section of the cross-section of the limiting block is adapted to the limiting groove, and the convex section of the cross-section of the limiting block is adapted to the limiting opening. The axial outer end of the moving-point coupling section is fixedly connected to the limiting section of the moving-point drive shaft by the elastic element, and the moving-point coupling section is slidably connected to the limiting groove area of ​​the moving-point drive shaft under the condition that the elastic element is subjected to a certain external force compression and tension. The clutch uses a combination of limiting blocks and limiting grooves to stabilize its rotation in the circumferential direction. In addition, it uses an elastic element combined with a telescopic push rod to store force in the axial direction. When the stored force of the elastic element is small, it is difficult to engage or disengage with the rotating fixed-point drive shaft. After the stored force is completed, a certain threshold force is formed to push or pull the drive shaft outward, which can disengage or engage with the rotating fixed-point drive shaft in a short time, thus improving the stability of clutch operation.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects:

[0017] 1. A three-dimensional silkworm rearing production line of the present invention includes silkworm frame stacking and unstacking mechanisms arranged at both ends of a conveyor belt assembly. The silkworm frame stacking and unstacking mechanism at the beginning of the conveyor belt assembly is used for unstacking silkworm frames, and the silkworm frame stacking and unstacking mechanism at the end of the conveyor belt assembly is used for stacking silkworm frames. This enables automatic unstacking and stacking. Silkworm frames are conveyed one by one through the conveyor belt assembly, allowing for manual feeding and disinfection operations within the conveyor belt assembly area, or related equipment can be installed for these operations. The silkworm frame stacking and unstacking mechanism uses two retractable, separable conveyor belt assemblies to transfer silkworm frames. First, the conveyor telescopic assembly and all telescopic modules are retracted to completely free up the accommodating space. Then, a transport vehicle directly pushes the stacked frames onto the ground within the accommodating space, where the silkworm frame stacking and unstacking mechanism lifts them upwards and performs the unstacking operation. Conversely, after stacking, the frames can be directly lowered onto a transport vehicle on the ground, improving operational efficiency. Furthermore, the conveyor belt and the transmission belt can circulate simultaneously under the synchronous shaft drive to transport silkworm frames, forming a segmented silkworm frame transport. A single conveyor drive unit drives the conveyor belt and the clutch drive unit simultaneously through the synchronous shaft, forming two or three sections of transport with speed differences. The middle section has a slower transport speed, which is convenient for feeding and disinfection operations, while the two ends have relatively faster transport speeds to quickly transport items such as adding or unloading trays. The clutch drive unit and the synchronous shaft work together to make the two conveyor belts of the silkworm frame stacking and unstacking mechanism move synchronously, and the synchronous shaft and the conveyor drive shaft work together to make the two conveyor belts of the transport mechanism move synchronously, improving the stability of silkworm frame transport. Moreover, the destacking process includes dismantling and outward conveying operations. A clutch drive is used to enable the transmission belt and the external conveyor to operate at a differential speed continuously. The fixed-point telescopic module and the moving-point telescopic module form a pre-destacking structure. The silkworm frame on the support rod of the moving-point telescopic module begins to move longitudinally forward with the conveyor belt as it descends to the conveyor belt. Then, the moving-point telescopic module promptly retracts the support rod and moves upward, cooperating with the fixed-point telescopic module to lower the next silkworm frame. During the period from when the moving-point telescopic module places the current silkworm frame to when it moves back and forth to lower the next silkworm frame, the conveyor belt completes the longitudinal outward conveying operation of the current silkworm frame. The dismantling and outward conveying operations are completed in staggered time, which can more than double the destacking speed and improve the destacking efficiency.

[0018] 2. The separable coupling uses a limiting block and a limiting groove to limit its rotation in the circumferential direction. It also uses an elastic element combined with a telescopic push rod to store force in the axial direction. When the stored force of the elastic element is small, it is difficult to engage or disengage with the rotating fixed-point drive shaft. After the stored force is completed, a certain threshold force is formed to push or pull the drive shaft outward, which can disengage or engage with the rotating fixed-point drive shaft in a short time, thus improving the stability of the clutch operation.

[0041] The specific implementation of the invention will be further described below with reference to the accompanying drawings. Example 1

[0042] See Figures 1-21 The three-dimensional silkworm rearing production line of this embodiment 1 includes the following:

[0043] The silkworm frame stacking and unstacking mechanism 100 includes two lifting components 1 arranged laterally opposite each other, with the two lifting components 1 spaced a certain distance apart laterally to form a receiving space for the silkworm frame 300. Each lifting component 1 includes a stand 11, a lifting assembly, a moving telescopic module 17, a fixed telescopic module 18, a conveyor belt assembly, and a conveyor telescopic assembly. The conveyor telescopic assembly is mounted on the stand 11 and can move laterally. The conveyor belt assembly is mounted on the conveyor telescopic assembly and can move longitudinally in a cyclic motion, extending into or out of the receiving space under the drive of the conveyor telescopic assembly. At least two fixed telescopic modules 1... 8 are arranged longitudinally and installed at the same height on the inner side of the upright, and the fixed-point telescopic module 18 can move laterally to extend into or withdraw from the receiving space; the lifting assembly is installed on the upright 11 and can move vertically; at least two movable-point telescopic modules 17 are arranged longitudinally and installed at the same height on the inner side of the lifting assembly, and the movable-point telescopic modules 17 can move laterally to extend into or withdraw from the receiving space; the fixed-point telescopic module 18 is located above the conveyor belt assembly, and the movable-point telescopic module can move vertically between the position below the conveyor belt assembly and the position above the fixed-point telescopic module under the drive of the lifting assembly;

[0044] The conveying mechanism 200 includes a frame 21 and a conveyor belt assembly. The conveyor belt assembly is mounted on the frame 21 and is capable of longitudinal cyclic movement. The conveyor belt assembly includes a conveyor belt component 22 and a conveyor drive component 23. The conveyor belt component 22 is mounted on the frame 21, and the conveyor drive component 23 is mounted below the conveyor belt component on the frame 21. The conveyor drive component 23 is connected to the conveyor belt component 22 to drive the conveyor belt component to cyclic movement.

[0045] The conveyor belt assembly has silkworm frame stacking / unstacking mechanisms 100 arranged at both longitudinal ends, and both longitudinal ends of the conveyor belt assembly are connected to two conveyor belt assemblies to transport silkworm frames; the silkworm frame stacking / unstacking mechanism at the beginning of the conveyor belt assembly is used for unstacking silkworm frames (unstacking machine), and the silkworm frame stacking / unstacking mechanism at the end of the conveyor belt assembly is used for stacking silkworm frames (stacking machine). Figure 2 As shown, by welding or bolting protective plates around the silkworm frame stacking and unstacking mechanism 100, the following can be obtained: Figure 1 The diagram shows a more complete production line.

[0046] The lifting assembly includes a lifting drive, a lifting platform 16, and a slide rail assembly. The slide rail assembly extends vertically and is mounted on the upright 11. Two slide rails 161 of the slide rail assembly are respectively arranged at the longitudinal ends of the upright 11. The longitudinal ends of the lifting platform 16 are slidably connected to the two slide rails 161. A pair of movable telescopic modules 17 are longitudinally arranged and mounted on the transverse inner side of the lifting platform. The lifting drive is mounted on the upright and can drive the lifting platform to move up and down along the slide rail assembly. As shown in the figure, this application uses the lifting motor 141 (lifting drive) combined with the lifting chain condition 15 to drive the lifting platform to move up and down along the grooved slide rail 161 as an example. The lifting chain condition 15, combined with the cyclical movement of the lifting sprocket, drives the lifting platform to move up and down under the drive of the lifting motor. Other alternative solutions, such as cylinders, will not be described here.

[0047] The telescopic conveyor assembly includes a telescopic push rod 121 and a telescopic guide rail assembly. Two telescopic guide rails 12 of the telescopic guide rail assembly extend laterally and are arranged at both ends of the longitudinal direction of the upright 11. The fixed ends of the telescopic guide rails 12 are mounted on the upright 11, and the movable ends are mounted on the conveyor belt assembly. The movable end of the telescopic push rod 121 is mounted on the conveyor belt assembly, and the fixed end of the telescopic push rod 121 is mounted on the upright 11. Driven by the telescopic push rod 121, the conveyor belt assembly can extend and retract along the telescopic guide rails to enter or exit the receiving space. As shown in the figure, this application uses an electric telescopic push rod 121 combined with a linear telescopic guide rail 12 as an example for explanation; other alternative solutions such as hydraulic cylinders are not described here.

[0048] The conveyor belt assembly includes a conveyor belt component 13 and a clutch drive component 25. The clutch drive component 25 includes a fixed drive shaft 251, a moving drive shaft 254, and a separable coupling. The axial inner end of the fixed drive shaft 251 is installed at the longitudinal inner end of the upright. The axial outer end of the moving drive shaft 254 extends laterally and is connected to the conveyor belt component 13. The axial inner end of the moving drive shaft 254 and the axial outer end of the fixed drive shaft 251 are laterally separable connected through the separable coupling. The moving drive shaft can drive the conveyor belt component to circulate under the transmission of the fixed drive shaft. The separable coupling includes a fixed-point coupling section 252 and a moving-point coupling section 253. The fixed-point coupling section 252 is installed at the axial outer end of the fixed-point drive shaft 251, and the moving-point coupling section 253 is installed at the axial inner end of the moving-point drive shaft 254. The moving-point coupling section 253 and the fixed-point coupling section 252 can be laterally brought into contact or separated under the push of the transmission telescopic assembly. When the fixed-point drive shaft 251 rotates in the forward direction, the axial outer end face of the fixed-point coupling section 252 is provided with two or more forward-arranged teeth, and the axial inner end face of the moving-point coupling section 253 is provided with two or more reverse-arranged teeth. The angle between the forward-rotating front end face of the teeth and the circumferential surface is 60°-90°, typically 75°, 85° or 90°. The backward-rotating rear end face of the teeth is an inclined surface that gradually convexes axially as it approaches the forward-rotating front end face. As shown in the figure, this application uses the clutch drive unit combined with the conveyor motor 23 to achieve simultaneous drive as an example. Other alternative solutions, such as configuring a motor drive for each transmission belt component, will not be described here.

[0049] The conveying drive unit includes a conveyor motor 23, a conveyor drive shaft, and a synchronous shaft 24. The conveyor motor 23 is connected to the synchronous shaft 24 via a conveyor sprocket set I. The synchronous shaft 24 is connected to the fixed-point drive shaft 251 via a conveyor sprocket set II. The synchronous shaft 24 is also connected to the conveyor drive shaft via a conveyor sprocket set III. Under the drive of the synchronous shaft 24, the conveyor drive shaft can drive the conveyor belt to circulate. The conveyor belt and the conveyor belt can circulate simultaneously under the drive of the synchronous shaft to convey the silkworm frame. The conveyor sprocket set II and the conveyor sprocket set III are composed of sprockets of different sizes to form a speed difference. The circulating speed of the conveyor belt is less than that of the conveyor belt, and the circulating speed of the stacker conveyor belt is greater than or equal to that of the destacking machine. The conveyor motor is installed in the longitudinal middle of the frame and below the conveyor belt. Two synchronous shafts extend laterally and are installed at both ends of the frame, also below the conveyor belt. Both synchronous shafts are connected to the conveyor motor, and each synchronous shaft is connected to the fixed-point drive shaft of the stacking / destacking mechanism on the same side. The inner axial end of the conveyor drive shaft is installed at one end of the frame, and the outer axial end extends laterally and is connected to the conveyor belt. The conveyor drive shaft is also connected to the synchronous shaft on the same side to drive the conveyor belt in a cyclic motion. As shown in the figure, this application uses a single conveyor motor drive combined with large and small sprockets and chains to achieve simultaneous cyclic motion of the stacking / destacking machine and the conveyor mechanism. Other alternative solutions, such as configuring separate motor drives for each transmission belt and conveyor belt, will not be discussed here.

[0050] Both the moving-point telescopic module 17 and the fixed-point telescopic module 18 are telescopic and supportable modules. This application uses their identical structure as an example for illustration, and existing technologies can be used. Other telescopic replacement solutions will not be described here. A telescopic motor, an inverted T-shaped support rod, and a plug rod are arranged on the base. The support rod is slidably arranged on the base. The drive shaft of the telescopic motor is hinged to the tail end of the support rod through the plug rod. Driven by the telescopic motor, the support rod is pushed to extend or retract its head end. The protruding section in the middle of the support rod serves as a limiting function.

[0051] The production line is also equipped with a controller, which consists of a PLC or 51 microcontroller and is connected to components such as the conveyor motor and telescopic push rod. It uses infrared sensors A1, A2, A3 and A4 to detect the position of the positioning frame or the moving point telescopic module and control the operation of each component. The controller and its components such as the conveyor motor are all existing components, and their connection and preset command execution control technology are all new technologies. They can be purchased directly from the market, connected with industry standard lines, and the parameters can be set according to the instruction manual. It will not be described in detail here.

[0052] The unstacking steps of the silkworm cocoon stacking and unstacking mechanism are as follows:

[0053] 1) Start the silkworm frame stacking and unstacking mechanism at the front end. All components return to their initial state. The fixed-point telescopic module (Module A) and the moving-point telescopic module (Module B) are in the retracted state, and the conveying telescopic component (Module C) is also in the retracted state. Module B is in the lowest position, and the accommodating space of the silkworm frame stacking and unstacking mechanism is completely empty.

[0054] 2) The operator uses a transport vehicle (such as a forklift) to transport the stack of 12 layers of silkworm frames 300 to the receiving space of the silkworm frame stacking and unstacking mechanism at the first end, and pushes the silkworm frame stack into place. Then, the operator controls the activation of module B. The four (two groups) modules located below the first layer of the stack (in order from bottom to top) extend their support rods. The operation can be reset by measuring the stroke, or it can be detected by receiving infrared sensor A1 to confirm that the silkworm frame stack has been pushed into place.

[0055] 3) Control the start of the lifting motor to drive the lifting platform to rise. When the lifting platform rises, the support rod of module B will lock the first layer (bottom layer) of silkworm frames to lift the silkworm frames to stack them. The lifting will stop when module B reaches the first stacking and unstacking position (the support rod of module A is between the first and second layers). The stacking and unstacking position can be determined by stroke measurement or by infrared sensors A3 and A4.

[0056] 4) Control the start of modules A and C. The four modules A extend their support rods, and modules C extend to push the conveyor belt into the receiving space to place it in the conveying position. Module C completes the pushing of the conveyor belt into the conveying position before modules B reach the lifting position. Driven by the clutch drive, the conveyor belt of module C moves longitudinally in a cyclic motion. Before module C starts, the external drive motor is started to move longitudinally in a cyclic motion when the conveyor belt extends to the conveying position.

[0057] 5) Control the start of the lifting motor, the lifting platform descends, and the upper layer of silkworm frames (the second layer of silkworm frames is stacked when unstacking for the first time) is stuck on the support rods of the 4 A modules, while the lifting platform continues to descend with a silkworm frame supported by it;

[0058] 6) When the lifting platform reaches the lifting position of module B (the silkworm frame on the support rod of module B is supported on the transmission belt, and the support rod of module B is at a certain distance below the silkworm frame, such as 1cm or 3cm below the silkworm frame), control the stop lifting motor to stop the lifting platform from descending, and at the same time control the start of module B to retract the support rod, completing the first unstacking; where the lifting position refers to the position of lifting the silkworm frame, which can be determined by stroke measurement or detected by infrared sensor A2;

[0059] 7) Control the start of the lifting motor, the lifting platform rises, and after the lifting platform has risen a certain distance (Module B is above the silkworm frames on the conveyor belt and a certain distance higher, such as 1cm or 3cm higher, thus detaching from the range of the silkworm frames it was placed in a moment ago), control the B module to extend its support rod, while the lifting platform continues to rise. The platform stops rising when the B module support rod catches the second or higher stack and is raised to the stacking position (the silkworm frames on the B module support rod are a certain distance above the A module support rod, such as 1cm or 3cm higher). The stacking position can be determined by stroke measurement or by infrared sensor A4. Infrared sensors A4 are used in pairs to detect two positions and also serve as height limits.

[0060] 8) Control the start of module A, and all four modules A will retract their support rods;

[0061] 9) Control the start of the lifting motor, the lifting platform descends, and stops descending when module B reaches the stacking and unstacking position (module A is located between two adjacent silkworm frames);

[0062] 10) Control the start of module A, and all four modules A will extend their support rods;

[0063] 11) Control the start of the lifting motor, the lifting platform descends, the upper layer of silkworm frames (the third layer or above of silkworm frames are stacked during the second unstacking) is stuck on the support rods of the 4 A modules, while the lifting platform continues to descend with a silkworm frame supporting it;

[0064] 12) When the lifting platform reaches the lifting position of module B, control the stop lifting motor to stop the lifting platform from descending, and at the same time control the start of module B to retract its support rod to complete the second unstacking.

[0065] 13) Repeat the above steps 7)-12) to unpile the 12-layer silkworm frames one by one onto the conveyor belt. During unpile, the operator uses a transport vehicle to move the next stack or perform other tasks.

[0066] The stacking and destacking steps of the silkworm frame stacking and destacking mechanism are the reverse of the destacking steps. The lifting motor is controlled to start and stop, causing module B to rise or fall. This raises the silkworm frames in the lifting position. During the continuous rise of module B, the silkworm frames on it are engaged with the stack of silkworm frames (partially stacked) on the support rod of module A, and lifted together. After module B reaches the stacking position, module A extends its support rod, and then module B continues to descend from the stacking position. The silkworm frame stack is then engaged on the support rod of module A. This process is repeated, stacking 12 layers of silkworm frames one by one onto the support rod of module A. Afterwards, module C retracts the conveyor belt, and module B continues to lower the 12-layer stack of silkworm frames from the stacking position onto the transport vehicle and retracts the support rod before transferring it out. Further details are omitted here. The stacking and destacking machines have the same structure, only their operating procedures differ.

[0067] As mentioned above, silkworm frame stacking and unstacking mechanisms are arranged at both ends of the longitudinal direction of the conveyor belt assembly. The mechanism at the beginning of the conveyor belt assembly is used for unstacking the silkworm frames, while the mechanism at the end is used for stacking them. This enables automatic unstacking and stacking. The silkworm frames are transported one by one through the conveyor belt assembly, allowing for manual feeding and disinfection within the conveyor belt assembly area, or the installation of related equipment. The silkworm frame stacking and unstacking mechanism uses two retractable, separate conveyor belt assemblies to transfer the silkworm frames. First, the retractable conveyor components and all retractable modules are retracted to completely free up the accommodating space. Then, a transport vehicle pushes the stacked frames directly onto the ground in the accommodating space, where the stacking and unstacking mechanism lifts them upwards and performs the unstacking operation. Conversely, after stacking, the frames can be directly lowered onto a transport vehicle on the ground, improving operational efficiency. Furthermore, the conveyor belt and the transmission belt can circulate simultaneously under the synchronous shaft drive to transport silkworm frames, forming a segmented silkworm frame transport. A single conveyor drive unit drives the conveyor belt and the clutch drive unit simultaneously through the synchronous shaft, forming two or three sections of transport with speed differences. The middle section has a slower transport speed, which is convenient for feeding and disinfection operations, while the two ends have relatively faster transport speeds to quickly transport items such as adding or unloading trays. The clutch drive unit and the synchronous shaft work together to make the two conveyor belts of the silkworm frame stacking and unstacking mechanism move synchronously, and the synchronous shaft and the conveyor drive shaft work together to make the two conveyor belts of the transport mechanism move synchronously, improving the stability of silkworm frame transport.

[0068] The destacking process of this stacking and destacking device includes dismantling and outward conveying operations. A clutch drive mechanism is used to ensure the differential speed of the transmission belt and the external conveyor. Modules A and B form a pre-destacking structure. The silkworm frame on the support rod of module B begins to move longitudinally forward with the conveyor belt as it descends onto it. Then, module B promptly retracts the support rod and moves upward, cooperating with module A to lower the next silkworm frame. During the period from when module B places the current silkworm frame to when it moves back and forth to lower the next silkworm frame, the conveyor belt completes the longitudinal outward conveying operation of the current silkworm frame. The dismantling and outward conveying operations are completed within the staggered time intervals, thus more than doubling the destacking speed and improving destacking efficiency.

[0069] See Figures 1-21Based on the aforementioned example, as an alternative, to address the issue of synchronous lifting of the two sets of lifting components, in this example, the lifting drive includes a lifting motor 141, a torque connecting rod 142, a steering box 14, a lifting shaft, and a lifting chain condition 15 (chain with sprocket). In each lifting component, the steering box 14 is mounted on the upright and positioned longitudinally inside the lifting platform. The lifting chain condition 15 is connected to the lifting platform 16. The axial ends of the lifting shaft extend longitudinally and are connected to the lifting chain condition 15 and the steering box 14, respectively, and the lifting shaft can drive the chain condition to circulate, thereby driving the lifting platform to move up and down. The axial ends of the torque connecting rod 142 extend laterally and are connected to the two steering boxes 14. The lifting motor 141 is mounted on an upright and is connected to the torque connecting rod 142 via a transmission connection. Thus, the lifting motor, through the torque connecting rod and the steering box, synchronously drives the two sets of lifting components, effectively improving the stability of lifting or lowering the silkworm frame during unstacking and stacking processes. Example 2

[0070] Based on Embodiment 1, Embodiment 2 has a power-accumulating clutch structure to ensure stable separation and engagement of the fixed-point drive shaft and the moving-point drive shaft during operation. For details not covered, please refer to Embodiment 1 above.

[0071] See Figures 1-21 In a three-dimensional silkworm rearing production line according to Embodiment 2, the separable coupling further includes an elastic element and a limiting block. The moving point coupling section 253 is slidably sleeved on the axial inner end of the moving point drive shaft 254. An axially extending limiting groove is provided on the outer wall of the axial inner end of the moving point drive shaft 254. An axially extending limiting opening is provided on the inner side wall of the moving point coupling section 253. The axial length of the limiting opening is less than that of the limiting groove. The length of the limiting block is adapted to the axial length of the limiting groove. The recessed section of the cross-section of the limiting block is adapted to the limiting groove. The convex section of the cross-section of the limiting block is adapted to the limiting opening. The axial outer end of the moving point coupling section 253 is fixedly connected to the limiting section 256 of the moving point drive shaft 254 by the elastic element. The moving point coupling section 253 is slidably connected to the limiting groove area of ​​the moving point drive shaft when the elastic element is subjected to a certain external force compression and tension. As shown in the figure, this application uses a spring as an elastic element fixedly connected to a radially protruding limiting section as an example for illustration. Other alternative solutions will not be described here.

[0072] If the moving point coupling section and the push rod are rigidly connected, the drive shaft will gradually become partially connected until it is fully engaged while the push rod pushes the moving point drive shaft to extend a certain distance. Conversely, it will gradually separate. During this period, the incomplete connection and rotation will cause changes in the contact force surface, which will affect the rotational stability and may even cause damage to the drive shaft.

[0073] Therefore, in this embodiment 2, a limiting block and a limiting groove are used to limit the rotation in the circumferential direction, and an elastic element combined with a telescopic push rod is used to store force in the axial direction. When the stored force of the elastic element is small, it is difficult to engage or disengage with the rotating fixed-point drive shaft. After the stored force is completed, a certain threshold force is formed to push or pull the driving shaft outward, which can disengage or engage with the rotating fixed-point drive shaft in a short time, thereby improving the stability of clutch operation.
