Description

Technical Field

[0001] This application relates to the field of mechanical transmission technology, and in particular to a conveying system. Background Technology

[0002] In the field of mechanical transmission, the development of automated production lines has greatly improved production efficiency and quality. With the continuous advancement of industrial production, the requirements for production line transportation systems are also increasing, especially in vehicle group transportation and reversing, where the performance directly affects the overall operational efficiency and stability of the production line. A good transportation and reversing system enables efficient flow of goods, reduces waiting time in the production process, lowers production costs, and is of great significance for improving a company's competitiveness. In modern manufacturing, many companies are constantly exploring more efficient and reliable transportation and reversing technologies to adapt to the ever-increasing production demands.

[0003] In existing automated production lines, accumulating conveyor systems are commonly used to transport workpiece-laden train sets. When train sets need to cross intersections in the production line, or when the production line layout requires train sets to change direction, switches, turntables, or complex multi-degree-of-freedom robotic arms are typically used. Fixed switch structures guide the direction of train set movement through specific track structures. Turntables utilize a rotating platform on which train sets can turn. Complex multi-degree-of-freedom robotic arms can achieve more flexible train set reversals, adjusting the position and direction of the train sets through the movement of multiple joints.

[0004] However, existing technologies have significant drawbacks. Existing devices such as turnouts, turntables, and multi-degree-of-freedom robotic arms often suffer from complex structures, requiring numerous components and intricate linkage mechanisms. This not only results in bulky equipment occupying significant production space but also in high manufacturing and maintenance costs. Furthermore, these devices lack positioning accuracy, easily experiencing minute displacements due to vibration or inertia, affecting the smooth operation of the trainset and the precision of subsequent processes. Summary of the Invention

[0005] To reduce costs, achieve efficient cargo transportation, ensure stable operation and reversal of cargo trolleys at different positions on the production line, and guarantee smooth operation of the conveying system, this invention provides a conveying system.

[0006] The conveying system provided by this invention adopts the following technical solution: A conveying system, comprising: Multiple transport modules are used to form multiple goods transport production lines. Each transport module includes an accumulation rail, a cross chain, a follower lever, and a cargo trolley assembly. The accumulation rail is arranged along the transport direction a of the production line and is fixed by a frame. The cross chain is in rolling contact with the accumulation rail. The follower lever is connected to the cross chain. The cargo trolley assembly is connected to the accumulation rail and travels along the accumulation rail. The cargo trolley assembly can be selectively connected to the follower lever. A drive module, connected to the cross chain, is used to drive the movement of the cross chain; A rotating module is connected to the accumulation rail. A first trolley pusher is provided beside the rotating module to push the cargo trolley group through the rotating module. The rotating module includes a fixed frame, transition channels, a rotating device, a backstop device, and an opening device. The fixed frame is connected to the frame body, and the transition channels are provided at both ends of the fixed frame along the production line transport direction a. The rotating device is located between the two transition channels and includes a rotating motor, a reducer, gears, a gear plate, a rotating drum, a rotating frame, and a stopping channel. The rotating motor is connected to the fixed frame, the reducer is connected to the rotating motor, and the gears are connected to the shaft of the reducer. The system is as follows: the geared disc is rotatably connected to the fixed frame via bearings; the geared disc meshes with the gear; the top end of the rotating cylinder is fixedly connected to the geared disc, and the bottom end is fixedly connected to the rotating frame; the docking channel is connected to the rotating frame, and the two ends of the docking channel are respectively aligned with two sets of transition channels; the docking channel is used for the cargo trolley group to enter and temporarily dock; the anti-reverse device is connected to the docking channel and is used to limit the movement of the cargo trolley group; the opening device is connected to the fixed frame and can be selectively connected to the anti-reverse device; when the opening device is connected to the anti-reverse device, it is used to release the anti-reverse state and allow the cargo trolley group to continue running. A translating trolley is positioned between two production lines that do not intersect in the transport direction a, located behind the rotating device along the transport direction a, and is used to transfer the cargo trolley group after reversal to another production line. Multiple detection modules are used to detect the occupancy status of the cargo trolley group; and The control module, the drive module, the first trolley machine, the rotation module and the detection module are all electrically connected to the control module.

[0007] By adopting the above technical solution, the conveying system operates by driving the cross chain via the drive module, which in turn moves the follower lever. The trolley group can be selectively connected to the follower lever and runs along the trolley channel of the accumulation rail, thus realizing the transportation of goods on the production line. When the trolley group carries the goods to the rotating module at the end of the accumulation rail, the first pusher pushes the trolley group into the parking channel of the rotating module. The detection module detects the entry or exit status of the trolley group and transmits the signal to the control module. The control module controls the rotating motor of the rotating device to drive the drum and rotating frame to rotate through the reducer, gears, and gear plate, thereby rotating the parking channel and completing the turning of the trolley group. The rotating module solves the problems of complex structure, inaccurate positioning, low safety and reliability, and poor versatility of the existing technology's reversing mechanism. Furthermore, the anti-reverse device can limit the movement of the trolley group. Opening the device can release the anti-reverse state and allow the trolley group to continue running, ensuring the stability and safety of the reversing process. The traverse crane can move the reversed cargo trolley group to another production line, realizing the transfer of goods between different production lines. This design enables the system to have multi-production line transportation capabilities, realize efficient transportation and reversal of goods, improve logistics efficiency, and ensure the stability and reliability of the cargo trolley group operation through the collaborative work of various modules, reducing the probability of failure.

[0008] Preferably, the docking channel and the transition channel have the same structure, both including two C-shaped traveling plates with opposite openings, and a fixing plate for connecting the two traveling plates; the wheels of the cargo trolley group are in rolling contact with the inner wall of the traveling plate; the fixing plate is C-shaped with its opening facing downwards, the fixing plate is fixedly connected to a corresponding fixing frame or rotating frame, and the traveling plate is fixedly connected to the inner wall of the fixing plate.

[0009] By adopting the above technical solution, the parking channel and the transition channel have the same structure, which facilitates manufacturing and installation, reduces costs, and allows the cargo trolley group to pass smoothly between the transition channel and the parking channel. The C-shaped traveling plate provides rolling tracks for the wheels of the cargo trolley group, ensuring smooth operation. The fixed bracket is fixedly connected to the fixed frame or rotating frame, ensuring the stability of the channel structure and allowing the cargo trolley group to pass smoothly through the rotating module.

[0010] Preferably, the anti-reverse device is provided in multiple sets, respectively arranged on both sides of the temporarily parked cargo trolley group; the anti-reverse device includes a first fixed plate, a second fixed plate, a thrust plate, a first stop block, and a second stop block. The first fixed plate and the second fixed plate are arranged parallel to each other, both connected to the parking channel and partially surrounding the outside of the parking channel. The thrust plate is located between the first fixed plate and the second fixed plate, and the thrust plate has two continuous bends in the bending direction. A shaft is connected to the top of the thrust plate, and the two ends of the shaft are respectively connected to the corresponding first fixed plate or second fixed plate. The plate is rotatably connected, and the thrust plate partially surrounds the docking channel. When the thrust plate is in its natural state, it is used to prevent the cargo trolley assembly from moving backward. The bottom of the thrust plate is provided with an entry ramp and a stop plane. The entry ramp is located on the side closer to the transition channel, and the stop plane is located on the side away from the transition channel. When the wheels of the cargo trolley assembly abut against the entry ramp, the thrust plate rotates along the shaft to enter the avoidance state. When both the front end and the rear end of the cargo trolley assembly are connected to the stop plane of the thrust plate, it is used to limit the movement of the cargo trolley assembly. The first stop is disposed on the top outer side of the thrust plate and is fixedly connected to the first fixing plate and the second fixing plate; the second stop is disposed below the thrust plate and is fixedly connected to the first fixing plate and the second fixing plate; the first stop and the second stop together are used to limit the rotation angle of the thrust plate.

[0011] By adopting the above technical solution, the anti-reverse device is securely connected to the parking channel via the first and second fixed plates, providing reliable support for the overall structure. In its natural state, the thrust plate is in the blocking position, effectively preventing the cargo trolley assembly from reversing. The bottom of the thrust plate has an entry ramp. When the cargo trolley assembly enters the parking channel, the wheels contact the ramp and apply pressure, pushing the thrust plate to rotate around its axle, thus entering a yielding state and allowing the trolley assembly to pass smoothly. After the trolley assembly has completely passed, the thrust plate automatically resets, with its front and rear ends reliably contacting the front and rear parts of the trolley assembly, respectively. This bidirectional limitation of the cargo trolley assembly through the anti-reverse plane ensures its stable parking within the parking channel. The first and second stops work together to limit the rotation angle of the thrust plate, ensuring its operation within a reasonable range and effectively guaranteeing the stable implementation of the anti-reverse function, thereby improving the safety and reliability of the conveying system.

[0012] Preferably, the anti-reverse device further includes a buffer pad connected to the inner wall of the thrust plate, the buffer pad being selectively used to abut against the docking channel.

[0013] By adopting the above technical solution, the buffer pad can selectively abut against the parking aisle, which can buffer the impact force generated when the cargo trolley group enters the parking aisle, reduce damage to the thrust plate and parking aisle, extend their service life, and reduce the noise generated when the cargo trolley group enters.

[0014] Preferably, the opening device includes a mounting plate, an opening cylinder, a pressure plate, a guide rod, a guide frame, and a guide sleeve. The mounting plate is fixedly connected to the fixed frame, the opening cylinder is connected to the mounting plate, the pressure plate is connected to the drive shaft of the opening cylinder, the pressure plate is optionally connected to the top of the thrust plate, the guide rod is connected to the pressure plate, the guide frame is connected to the mounting plate, and the guide sleeve is connected to the guide frame and sleeved on the guide rod, slidingly engaging with the guide rod.

[0015] By adopting the above technical solution, after the conveyor trolley 141 completes its reversal, when it is necessary to release the anti-reverse state of the cargo trolley group, the control module controls the opening cylinder to move. The drive shaft of the opening cylinder drives the pressure plate to move, and the pressure plate pushes the thrust plate to rotate along the shaft, causing the thrust plate to enter the avoidance state. The first pusher then pushes the cargo trolley group to continue running and disengage from the rotating module. During this process, the guide rod slides within the guide sleeve, providing guidance for the movement of the pressure plate, ensuring the stability and accuracy of the action. This allows for flexible and reliable release of the anti-reverse state of the cargo trolley group, making the operation of the conveying system smoother.

[0016] Preferably, the rotating module further includes a positioning device, one end of which is connected to the transition channel and the other end of which is connected to the docking channel; The positioning device includes a fixed guide assembly, a positioning cylinder, a connecting plate, and a positioning component. The fixed guide assembly includes a fixed box, a positioning pin, and guide wheels. The fixed box is connected to the transition channel. The positioning pin passes through the fixed box. Multiple guide wheels are provided and are all located inside the fixed box. The guide wheels are rotatably connected to the fixed box. The multiple guide wheels are respectively located on both sides of the positioning pin and roll against the positioning pin to limit the positioning pin. The positioning cylinder is connected to the fixed box, and one end of the connecting plate is hinged to the drive shaft of the positioning cylinder, while the other end is connected to the end of the positioning pin away from the docking channel. The positioning component includes a positioning frame and positioning wheels. The positioning frame is connected to the docking channel. Multiple positioning wheels are provided, and each is rotatably connected to the positioning frame. When the docking channel is aligned with the transition channel, the positioning pin is inserted between two positioning wheels, and the positioning wheel rolls against the positioning pin.

[0017] By adopting the above technical solution, the positioning device enables precise docking between the stopping channel and the transition channel in the rotating device, improving the accuracy of track docking. When the stopping channel and the transition channel need to be aligned, the positioning cylinder actuates, driving the positioning pin to move via the connecting plate. The positioning pin, within the fixed box, is limited by the rolling contact of multiple guide wheels, smoothly moving towards the positioning assembly. Once the stopping channel and the transition channel are aligned, the positioning pin inserts between two positioning wheels on the positioning frame. The positioning wheels and the positioning pin roll and contact, completing the positioning and ensuring precise docking of the rotating module's track with the accumulation rail. This guarantees that the tracks are on the same parallel and vertical lines, improving the stability and reliability of the system operation.

[0018] Preferably, the system further includes a cross module for ensuring the stable passage of the cargo trolley group at the intersection of two production lines. The cross module includes a baffle plate device, a load-bearing half-rail device, a chain track, a second trolley pusher, and a reversing device. The baffle plate device includes a first baffle plate, a second baffle plate, a third baffle plate, and a fourth baffle plate. The first and second baffle plates are arranged in parallel and spaced apart along a first direction x, while the third and fourth baffle plates are arranged in parallel and spaced apart along a second direction y. The load-bearing half-rail device includes a first load-bearing half-rail, a second load-bearing half-rail, a third load-bearing half-rail, and a fourth load-bearing half-rail. Each of these load-bearing half-rails has a corner. One end of the first load-bearing half-rail is connected to the first baffle plate, and the other end... One end of the second bearing half rail is connected to the third bracket, and the other end of the third bearing half rail is connected to the second bracket. One end of the third bearing half rail is connected to the first bracket and the other end of the fourth bearing half rail. One end of the fourth bearing half rail is connected to the second bracket and the other end of the fourth bearing half rail. The first bearing half rail and the third bearing half rail cooperate, and the second bearing half rail and the fourth bearing half rail cooperate to form a track extending along the first direction x. The first bearing half rail and the second bearing half rail cooperate, and the third bearing half rail and the fourth bearing half rail cooperate to form a track extending along the second direction y. The angle between the first direction x and the second direction y is set. One end of the chain track is connected to the first guide plate and the other end is connected to the second guide plate, which is used to drive the cargo trolley group to run along the track in the first direction x; the trolley pusher is located next to the bearing half-rail device and is used to drive the cargo trolley group to run along the track in the second direction y. The reversing device is connected to both the track in the first direction x and the track in the second direction y, and is used to selectively connect the track in the first direction x or the track in the second direction y.

[0019] By adopting the above technical solution, the baffle plate device and the load-bearing half-rail device work together to form tracks in different directions. The chain track enables the cross chain to drive the cargo trolley group to run along the first direction x track, and the pusher drives the cargo trolley group to run along the second direction y track. The reversing device controls and selects the tracks connecting different directions, which can realize the stable passage of the cargo trolley group between tracks in different directions at the intersection of two production lines, meet the needs of the trolley group to change the running direction in the production line layout, and has a reasonable structural design and stable operation.

[0020] Preferably, the outer side of the corner of both the first and fourth load-bearing half rails is provided with an arc surface, and the inner side of the corner is provided with a protrusion; the reversing device includes a reversing cylinder and a reversing connecting assembly, both ends of the reversing cylinder are connected to the reversing connecting assembly, and the two sets of reversing connecting assemblies are respectively provided with corresponding protrusions of the first and fourth load-bearing half rails; The reversing connection assembly includes a rocker arm, a square sleeve, a rotating shaft, a lower tongue plate, and an upper tongue plate. One end of the rocker arm is hinged to the reversing cylinder, and the other end is fixedly connected to the square sleeve. The rotating shaft is vertically arranged, and the square sleeve is fitted onto the top end of the rotating shaft. The rotating shaft passes through a corresponding protrusion and is rotatably connected to the protrusion. The lower tongue plate is fixedly connected to the bottom end of the rotating shaft, and the upper tongue plate is fixedly connected to the lower tongue plate. The upper tongue plate has a concave surface that matches the arc surface. The upper tongue plate is connected to the corresponding first bearing half rail or the second bearing half rail. The four-rail bearing half-rail has a circular arc surface sliding fit. The upper tongue plate can be selectively located on the track in the first direction x or the track in the second direction y. The upper tongue plate is provided with a first limiting surface and a second limiting surface. When the upper tongue plate is located on the track in the second direction y and the first limiting surface is parallel to the first direction x, it is used to allow the cargo trolley group to pass along the track in the first direction x. When the upper tongue plate is located on the track in the first direction x and the second limiting surface is parallel to the second direction y, it is used to allow the cargo trolley group to pass along the track in the second direction y.

[0021] By adopting the above technical solution, during use, the reversing cylinder actuates, driving the rocker arm to move. The rocker arm, through the square sleeve, rotates the shaft, thereby driving the lower and upper tongue plates to rotate. The upper tongue plate can select its position between the track in the first direction x and the track in the second direction y. When the cargo trolley needs to pass along the track in the first direction x, the reversing cylinder drives the upper tongue plate to be positioned on the track in the second direction y, with the first limiting surface parallel to the first direction x. When the cargo trolley needs to pass along the track in the second direction y, the reversing cylinder drives the upper tongue plate to be positioned on the track in the first direction x, with the second limiting surface parallel to the second direction y, thus realizing flexible switching of the cargo trolley between tracks in different directions. At the same time, the concave surface on the upper tongue plate, which matches the arc surface, allows it to slide and connect with the arc surface of the corresponding first or fourth load-bearing half-rail, ensuring the smooth passage of the cargo trolley and effectively improving the transportation efficiency and flexibility of the conveying system.

[0022] Preferably, the drive module includes a support frame, a drive motor, a torque converter, a connecting shaft, a first sprocket, a second sprocket, a drive chain, a worm gear, and a bearing housing. The drive motor is connected to the support frame, the torque converter is connected to the drive shaft of the drive motor, the connecting shaft is connected to the torque converter, the first sprocket is connected to the connecting shaft, the second sprocket is connected to the worm gear, the drive chain is sleeved on the first sprocket and the second sprocket and meshes with both sprockets, and both ends of the worm gear are rotatably connected to the support frame through the bearing housing. The support frame is provided with a drive channel for the cross chain to travel, and the worm gear is threadedly engaged with the cross chain.

[0023] By adopting the above technical solution, after the drive motor starts, the power is transmitted to the torque converter via the drive shaft. The torque converter smoothly outputs the power to the connecting shaft, which drives the first sprocket to rotate. The first sprocket drives the second sprocket to rotate via the drive chain, thereby causing the worm to rotate. Since the worm is threadedly engaged with the cross chain, the rotation of the worm drives the cross chain to travel on the drive channel of the support frame, thus achieving the drive of the cross chain. This structural design makes the drive module compact, the power transmission efficient and stable, and can effectively reduce the failure rate. At the same time, the connection method and transmission relationship between the components are clear, which facilitates installation, debugging and daily maintenance, reducing the cost of use and maintenance.

[0024] In summary, the present invention has the following beneficial effects: 1. In operation, this conveying system uses a drive module to move a cross chain, which in turn moves a follower lever. The trolley group can selectively connect to the follower lever and run along the trolley channel of the accumulation rail, thus transporting goods on the production line. When reaching the intersection of two production lines, a cross module ensures the stable passage of the trolley group, preventing collisions. Upon reaching the rotating module at the end of the accumulation rail, the first pusher pushes the trolley group into the rotating module's stopping channel. A detection module detects the trolley group's entry or exit and transmits a signal to the control module. The control module controls the rotating motor of the rotating device to drive the rotating drum and rotating frame through a reducer, gears, and a gear plate, thereby rotating the stopping channel and completing the turning of the trolley group. The rotating module solves the problems of complex structure, inaccurate positioning, low safety and reliability, and poor versatility in existing technologies for reversing mechanisms. Furthermore, a stop device limits the trolley group; opening the device releases the stop, allowing the trolley group to continue running, ensuring the stability and safety of the reversing process. The translation trolley can transfer the reversed cargo trolley group to another production line, realizing the transfer of goods between different production lines. This design enables the system to have multi-production line transportation capabilities, realize efficient transportation and reversal of goods, improve logistics efficiency, and ensure the stability and reliability of the cargo trolley group operation through the collaborative work of various modules, reducing the probability of failure. 2. Precise positioning and reliable operation: The rotating module is equipped with a positioning device to effectively eliminate gaps after rotation into place, ensuring high precision in track docking and improving system operational stability.

[0042] A conveying system, referring to Figure 1 , Figure 2 and Figure 3 The system comprises multiple transport modules 1, drive modules 2, cross-connection modules 3, rotation modules 5, translation trolleys 6, detection modules 7, and a control module. The multiple transport modules 1 constitute multiple production lines for transporting goods. Drive modules 2 drive the transport modules 1 to move and transport goods. Cross-connection modules 3 ensure the stable passage of cargo trolley groups 14 at intersections. Rotation modules 5 reverse the direction of cargo trolley groups 14. Translation trolleys 6 move the reversed cargo trolley groups 14. Detection modules 7 detect the occupancy status of cargo trolley groups 14. The control module provides unified control of all modules, achieving efficient transport and reversal of goods on the production line, thus improving the production line's operational efficiency and stability.

[0043] Reference Figure 1 and Figure 2 The transport module 1 includes an accumulation rail 11, a cross chain 12, a follower lever 13, and a cargo trolley assembly 14. The accumulation rail 11 is arranged along the corresponding production line transport direction a and is fixed to the ground or wall via a frame. A transport channel 111, a follower channel 112, and a travel channel 113 are sequentially arranged on the accumulation rail 11, with the follower channel 112 connecting the transport channel 111 and the travel channel 113. The cross chain 12 is located within the transport channel 111 and rolls in contact with the accumulation rail 11. The follower lever 13 is located within the follower channel 112 and is connected to the bottom of the cross chain 12. The follower lever 13 and the cross chain 12 are connected by bolts to ensure synchronous movement.

[0044] Reference Figure 2The cargo trolley group 14 includes a conveying trolley 141, a connecting rod 142, and a cargo carrying rod 143. Each cargo trolley group 14 includes one or two conveying trolleys 141, and each conveying trolley 141 is fixedly connected to a connecting rod 142. The connecting rod 142 is rotatably connected to the cargo carrying rod 143 through bearings. If there is one conveying trolley 141, the connecting rod 142 is located in the middle section of the cargo carrying rod 143; if there are two conveying trolleys 141, the two connecting rods 142 are respectively arranged at both ends of the cargo carrying rod 143. In this embodiment, there are two conveying trolleys 141.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The wheels of the conveying trolley 141 are located within the travel channel 113 and roll in contact with the accumulation rail 11. The conveying trolley 141 can be selectively connected to the follow-up lever 13, and the connection can be achieved through hooks or slots, etc., to facilitate the connection and separation of the cargo trolley group 14.

[0046] The combination logic of the components in transport module 1 is as follows: the cross chain 12 moves within transport channel 111 under the drive of drive module 2, driving the follower lever 13 to move within follower channel 112. When the cargo trolley group 14 needs to move, it connects with the follower lever 13, thus moving together with the cross chain 12. This combination method enables the goods to be transported in an orderly manner on the production line, improving transport efficiency.

The support frame 21 supports the various components of the drive module 2 and can be welded from steel, providing high stability. The drive motor 22 is fixedly connected to the support frame 21, providing power to the entire drive module 2. The drive motor 22 can be selected from motors of appropriate power to meet the transportation needs of the production line.

[0048] Reference Figure 3 Torque generator 23 is fixedly connected to the drive shaft of drive motor 22 and is used to adjust torque. Torque generator 23 can be mechanical or hydraulic, depending on the actual situation. Connecting shaft 24 is rotatably connected to support frame 21 and fixedly connected to torque generator 23, used to transmit power. First sprocket 25 is fixedly connected to connecting shaft 24, second sprocket 26 is fixedly connected to worm gear 28, and drive chain 27 is sleeved on first sprocket 25 and second sprocket 26, and meshes with both first sprocket 25 and second sprocket 26. Drive chain 27 can be roller chain or toothed chain, with good transmission performance. Both ends of worm gear 28 are rotatably connected to support frame 21 through bearing seats 29.

[0049] Reference Figure 2 and Figure 3 The support frame 21 is provided with a drive channel 211, which is a component of the transport module 1 and is used to align and fix with the accumulation rail 11. The cross chain 12 passes through the drive channel 211, and the worm gear 28 is threadedly engaged with the cross chain 12 to transmit the power of the drive motor 22 to the cross chain 12.

[0050] Reference Figure 2 and Figure 3 The drive channel 211 includes two symmetrically arranged channel structures, each comprising a mounting vertical plate 2111, a first horizontal bar 2112, and a second horizontal bar 2113. Multiple mounting vertical plates 2111 are arranged in parallel and at equal intervals. The mounting vertical plates 2111 are fixedly connected to the support frame 21. The length directions of both the first horizontal bar 2112 and the second horizontal bar 2113 are parallel to the axis of the worm gear 28, and both are fixedly connected to the mounting vertical plates 2111. The first horizontal bar 2112 is located below the second horizontal bar 2113, with space provided for the cross chain 12 to pass through. The cross chain 12 rolls against the first horizontal bar 2112. A distance is maintained between the first horizontal bar 2112 and the support frame 21 to allow the follower lever 13 to pass through, avoiding interference.

[0051] The combination logic of the components in drive module 2 is as follows: After drive motor 22 starts, torque is adjusted by torque converter 23 to transmit power to connecting shaft 24. Connecting shaft 24 drives first sprocket 25 to rotate, first sprocket 25 drives second sprocket 26 to rotate via drive chain 27, which in turn drives worm gear 28 to rotate. Worm gear 28 engages with cross chain 12 by thread, driving cross chain 12 to move within transport channel 111. This combination method achieves efficient power transmission and ensures stable operation of cross chain 12.

[0054] Reference Figure 4 and Figure 5 The first load-bearing half-rail 321 and the third load-bearing half-rail 323 cooperate, and the second load-bearing half-rail 322 and the fourth load-bearing half-rail 324 cooperate to form a track extending along the first direction x. The first load-bearing half-rail 321 and the second load-bearing half-rail 322 cooperate, and the third load-bearing half-rail 323 and the fourth load-bearing half-rail 324 cooperate to form a track extending along the second direction y. The load-bearing half-rails are made of channel steel, with their openings facing each other, and have good load-bearing capacity.

[0055] Reference Figure 4 and Figure 5 The first scraper plate 311, the second scraper plate 312, the third scraper plate 313 and the fourth scraper plate 314 are fixedly connected to the scraper plate of the accumulation rail 11 by bolts. The rail in the first direction x is aligned with the travel channel 113 of the accumulation rail 11 along the first direction x; the rail in the second direction y is aligned with the travel channel 113 of the accumulation rail 11 along the second direction y, so as to realize that the conveying trolley 141 in the first direction x or the second direction y can stably pass through the intersection of the two production lines.

[0056] Reference Figure 2 and Figure 4 One end of the chain track 33 is fixedly connected to the first guide plate 311, and the other end is fixedly connected to the second guide plate 312. It is composed of two channel steels with opposite openings, and is used to drive the cargo trolley group 14 to run along the track in the first direction x. The middle section of the chain track 33 is arched to avoid interference with the conveying trolley 141 from the second direction y.

[0057] Reference Figure 1 , Figure 2 and Figure 5 The second trolley pusher 34 is located beside the supporting semi-rail device 32 and is used to drive the cargo trolley group 14 to run along the track in the second direction y. The second trolley pusher 34 includes a drive motor, drive sprockets, drive chain and push plate. The drive motor is fixedly connected to the frame. There are two drive sprockets, both of which are rotatably connected to the frame through shafts. The drive chain is sleeved on the two drive sprockets and meshes with the drive sprocket. The push plate is fixedly connected to the drive chain.

[0058] The motor drives the sprocket to rotate, which in turn drives the chain to move, which in turn drives the pusher plate to move the conveyor trolley 141. By driving the motor to rotate forward and reverse, the pusher plate moves back and forth.

[0059] Reference Figure 4 , Figure 5 and Figure 6 The reversing device 35 is connected to both the track in the first direction x and the track in the second direction y, and is used to control the selection of the track connecting the first direction x or the track in the second direction y. The outer sides of the corners of the first bearing half-rail 321 and the fourth bearing half-rail 324 are each provided with an arc surface 3201, and the inner sides of the corners are each provided with a protrusion 3202. The reversing device 35 includes a reversing cylinder 351 and reversing connecting assemblies. Both ends of the reversing cylinder 351 are connected to reversing connecting assemblies. The two sets of reversing connecting assemblies are centrally symmetrically distributed and are respectively provided with corresponding protrusions 3202 of the first bearing half-rail 321 and the fourth bearing half-rail 324.

[0060] Reference Figure 4 , Figure 5 and Figure 6The reversing connection assembly includes a rocker arm 352, a square sleeve 353, a rotating shaft 354, a lower tongue plate 355, and an upper tongue plate 356. One end of the rocker arm 352 is hinged to the reversing cylinder 351, and the other end is fixedly connected to the square sleeve 353. The rotating shaft 354 is vertically arranged and passes through the corresponding protrusion 3202, and is rotatably connected to the protrusion 3202. The square sleeve 353 is fitted onto the top of the rotating shaft 354 and is fixedly connected to the rotating shaft 354. The lower tongue plate 355 is cam-shaped and is fixedly connected to the bottom end of the rotating shaft 354. The upper tongue plate 356 is fixedly connected to the top of the lower tongue plate 355. The upper tongue plate 356 is provided with a concave surface 3561 that matches the arc surface 3201. The upper tongue plate 356 slides in cooperation with the arc surface 3201 of the corresponding first bearing half rail 321 or fourth bearing half rail 324. The upper tongue plate 356 can be selectively located on the track in the first direction x or the track in the second direction y.

[0061] Reference Figure 2 , Figures 4 to 6 The upper tongue plate 356 is provided with a first limiting surface 3562 and a second limiting surface 3563, and the lower tongue plate 355 is provided with a first sidewall flush with the first limiting surface 3562 and a second sidewall flush with the second limiting surface 3563. When the upper tongue plate 356 is located in the track in the second direction y, the first limiting surface 3562 is parallel to the first direction x and flush with the edges of the first bearing half rail 321, the second bearing half rail 322, the third bearing half rail 323 and the fourth bearing half rail 324 along the first direction x, so as to allow the cargo trolley group 14 to pass smoothly through the track in the first direction x.

[0062] Reference Figures 1 to 2 , Figures 4 to 6 When the upper tongue plate 356 is located in the track in the first direction x, the second limiting surface 3563 is parallel to the second direction y and flush with the edges of the first bearing half rail 321, the second bearing half rail 322, the third bearing half rail 323 and the fourth bearing half rail 324 along the first direction x, so as to make the cargo trolley group 14 pass smoothly through the track in the second direction y.

[0063] In use, the reversing cylinder 351 actuates, driving the rocker arm 352 to move. The rocker arm 352 rotates the shaft 354 via the square sleeve 353, thereby driving the lower tongue plate 355 and the upper tongue plate 356 to rotate. The upper tongue plate 356 can select a position between the track in the first direction x and the track in the second direction y. When the cargo trolley assembly 14 needs to pass along the track in the first direction x, the reversing cylinder 351 drives the upper tongue plate 356 to be located on the track in the second direction y, with the first limiting surface 3562 parallel to the first direction x. When the cargo trolley assembly 14 needs to pass along the track in the second direction y, the reversing cylinder 351 drives the upper tongue plate 356 to be located on the track in the first direction x, with the second limiting surface 3563 parallel to the second direction y, thus realizing the flexible switching of the cargo trolley assembly 14 between tracks in different directions. Meanwhile, the concave surface 3561 on the upper tongue plate 356, which matches the arc surface 3201, allows it to slide and cooperate with the arc surface 3201 of the corresponding first bearing half rail 321 or fourth bearing half rail 324, ensuring the smooth passage of the cargo trolley group 14 and effectively improving the transportation efficiency and flexibility of the conveying system.

[0064] In this embodiment, the rotation angle of the upper tongue plate 356 is precisely designed to be ±25° (counterclockwise or clockwise), enabling the upper tongue plate 356 to select between the track in the first direction x and the track in the second direction y. Before and after rotating 25°, the concave surface 3561 and the arc surface 3201 maintain a solid safety gap of ≥0.8mm.

[0065] The combination logic of the components in the cross module 3 is as follows: Controlled by the reversing device 35, the cargo trolley group 14 can choose to run along either the track in the first direction x or the track in the second direction y. When it needs to run along the first direction x, the cross chain 12 drives the cargo trolley group 14 forward via the chain track 33; when it needs to run along the second direction y, the trolley pusher pushes the cargo trolley group 14 forward. This combination method allows the cargo trolley group 14 to flexibly change direction at the intersection, improving the transportation flexibility of the production line.

[0066] Reference Figure 1 and Figure 7 The rotating module 5 is located at the end of the accumulation rail 11. In this embodiment, two rotating modules 5 are spaced apart, each corresponding to one of the two conveying trolleys 141 in the cargo trolley group 14, and are used to rotate and change the direction of their respective conveying trolleys 141. The two rotating modules 5 are spaced apart, and the accumulation rail 11 is provided between the two rotating modules 5 and is fixedly connected to the accumulation rail 11. A section of the accumulation rail 11 is also fixedly installed at the rear end of the rotating module 5 along the transport direction a, allowing the cargo trolley group 14 to detach from the rotating module 5.

[0067] Reference Figure 1 , Figure 7 and Figure 8The rotating module 5 includes a fixed frame 51, a transition channel 52, a rotating device 53, a backstop device 54, and an opening device 55. The fixed frame 51 is U-shaped, with its two free ends fixedly connected to the frame body, providing support for the rotating module 5. The horizontal section of the fixed frame 51 is rectangular. The fixed frame 51 can be welded from steel, providing high stability. A first trolley pusher 4 is located on the side of the rotating module 5, used to push the cargo trolley group 14 through the rotating module 5. The structure of the first trolley pusher 4 is the same as that of the second trolley pusher 34.

[0068] Reference Figure 1 , Figure 7 and Figure 8 The fixed frame 51 has transition channels 52 at both ends along the transport direction a of the production line. The transition channels 52 are used for the passage of the cargo trolley group 14. The rotating device 53 is located between the two transition channels 52, and one end of the transition channel 52 is fixedly connected to the accumulation rail 11 through the rotating device 53. The structure of the transition channel 52 is similar to that of the accumulation rail 11, and it can be made of the same material to ensure that the cargo trolley group 14 can pass smoothly.

[0069] Reference Figure 8 The rotating device 53 includes a rotary motor 531, a reducer 532, a gear 533, a gear disc 534, a rotating drum 535, a rotating frame 536, and a docking channel 537. The rotary motor 531 is fixedly connected to the top of the fixed frame 51, the reducer 532 is fixedly connected to the drive shaft of the rotary motor 531, and the gear 533 is fixedly connected to the shaft of the reducer 532. The gear disc 534 is rotatably connected to the fixed frame 51 via bearings. The axis of the gear disc 534 is vertically arranged, and the gear disc 534 meshes with the gear 533. The top end of the rotating drum 535 is fixedly connected to the inner wall of the gear disc 534, and the bottom end is fixedly connected to the rotating frame 536. The rotating drum 535 and the gear disc 534 are coaxially arranged.

[0070] The rotary motor 531 drives the gear 533 to rotate through the reducer 532. The gear 533 meshes with the gear disc 534, thereby driving the rotating drum 535 and the rotating frame 536 to rotate, realizing the rotation of the docking channel 537.

[0071] Reference Figure 1 , Figure 7 and Figure 8The parking channel 537 is fixedly connected to the rotating frame 536. The parking channel 537 is used for the loading trolley group 14 to enter and temporarily park. When the rotating device 53 is in an idle state, the two ends of the parking channel 537 are respectively aligned with the two sets of transition channels 52. The structure of the parking channel 537 is the same as that of the transition channel 52, both including a traveling plate 521 and a fixed bracket 522. The traveling plate 521 is C-shaped and there are two of them. The two traveling plates 521 are spaced apart and their openings face each other. The wheels of the conveying trolley 141 roll against the traveling plate 521 to allow the conveying trolley 141 to move. There are multiple fixed brackets 522, which are spaced apart along the transport direction a of the production line. The fixed brackets 522 are C-shaped and their openings face downwards. Their tops are fixedly connected to the corresponding rotating frame 536 or fixed frame 51. The outer walls of the two traveling plates 521 are fixedly connected to the inner wall of the fixed bracket 522 and are located at the bottom of the fixed bracket 522. The space reserved above the traveling plates 521 avoids interference.

[0072] Reference Figure 7 and Figure 8 Two sets of anti-reverse devices 54 are provided, respectively located on both sides of the parking channel 537 along the transport direction a, and both connected to the parking channel 537. The two sets of anti-reverse devices 54 are arranged at intervals along the transport direction a, and are respectively arranged on both sides of the temporarily parked cargo trolley group 14 to limit the movement of the cargo trolley group 14. The anti-reverse devices 54 can prevent the cargo trolley group 14 from sliding or moving during rotation, ensuring its stability.

[0073] Reference Figure 7 , Figure 9 and Figure 10 The anti-reverse device 54 includes a first fixed plate 541, a second fixed plate 542, a thrust plate 543, a first stop block 544, a second stop block 545, and a buffer pad 546. The first fixed plate 541 and the second fixed plate 542 are vertically and parallelly arranged and are both fixedly connected to the parking channel 537. Both the first fixed plate 541 and the second fixed plate 542 are C-shaped and partially enclose the outside of the parking channel 537. The thrust plate 543 has two continuous bends in the bending direction. The thrust plate 543 is located between the first fixed plate 541 and the second fixed plate 542. A shaft is fixedly connected to the top of the thrust plate 543. The two ends of the shaft are rotatably connected to the corresponding first fixed plate 541 or second fixed plate 542, respectively. The thrust plate 543 partially encloses the parking channel 537. When the thrust plate 543 is in its natural state, the cargo trolley group 14 is stopped from moving due to its own weight.

[0074] Reference Figure 7 , Figure 8 and Figure 10The thrust plate 543 has an entry ramp 5431 and a stop plane 5432 at its bottom. The entry ramp 5431 of the thrust plate 543 is located on the side closer to the transition channel 52, and the stop plane 5432 is located on the side away from the transition channel 52. When the conveyor trolley 141 enters the parking channel 537, the wheels of the conveyor trolley 141 abut against the entry ramp 5431, and the thrust plate 543 rotates along the shaft to enter a clearance state, allowing the conveyor trolley 141 to pass through the thrust plate 543. When the conveyor trolley 141 is located between the two sets of stop devices 54, the front end and rear end of the conveyor trolley 141 abut against the adjacent stop plane 5432, respectively, to limit the movement of the conveyor trolley 141.

[0075] Reference Figure 9 and Figure 10 A first stop 544 is disposed on the top outer side of the thrust plate 543 and is fixedly connected to the first fixing plate 541 and the second fixing plate 542; a second stop 545 is disposed below the thrust plate 543 and is fixedly connected to the first fixing plate 541 and the second fixing plate 542. A buffer pad 546 is fixedly connected to the inner sidewall of the thrust plate 543, and the buffer pad 546 can selectively abut against the docking channel 537. When the thrust plate 543 is in its natural state, the buffer pad 546 abuts against the docking channel 537; the first stop 544 and the second stop 545 together limit the rotation angle of the thrust plate 543. When the thrust plate 543 enters the avoidance state, the thrust plate 543 abuts against the first fixing plate 541 and the second fixing plate 542, and the buffer pad 546 disengages from the docking channel 537.

[0076] Reference Figure 7 , Figure 9 and Figure 11 The opening device 55 is connected to the fixed frame 51 and can be selectively connected to one of the anti-reverse devices 54. After the rotating module 5 drives the conveying trolley 141 to rotate, the opening device 55 is located above the anti-reverse device 54 at the rear end of the transport direction a, and is used to release the anti-reverse state of the anti-reverse device 54 so that the cargo trolley group 14 can continue to run.

[0077] Reference Figure 1 , Figure 7 , Figure 9 and Figure 11The opening device 55 includes a mounting plate 551, an opening cylinder 552, a pressure plate 553, a guide rod 554, a guide frame 555, and a guide sleeve 556. The mounting plate 551 is vertically mounted and its top is fixedly connected to the fixed frame 51. The opening cylinder 552 is fixedly connected to the mounting plate 551, and the pressure plate 553 is fixedly connected to the drive shaft of the opening cylinder 552. An extension plate 5433 is fixedly connected to the top of the thrust plate 543, and the bottom of the pressure plate 553 can optionally abut against the top of the extension plate 5433. The guide rod 554 is fixedly connected to the top of the pressure plate 553, the guide frame 555 is fixedly connected to one side of the mounting plate 551, and the guide sleeve 556 is fixedly connected to the guide frame 555 and sleeved on the guide rod 554, slidingly engaging with the guide rod 554.

[0078] After the conveyor trolley 141 completes its reversal, when it is necessary to release the anti-reverse state of the cargo trolley group 14, the control module controls the opening cylinder 552 to operate. The drive shaft of the opening cylinder 552 drives the pressure plate 553 to move. The pressure plate 553 pushes the thrust plate 543 to rotate along the shaft, causing the thrust plate 543 to enter the avoidance state. The first pusher 4 then pushes the cargo trolley group 14 to continue running and disengage from the rotating module 5. Reference Figure 8 , Figure 9 and Figure 12 The rotating module 5 also includes a positioning device 56, one end of which is connected to the transition channel 52 and the other end to the docking channel 537. The positioning device 56 includes a fixed guide assembly 561, a positioning cylinder 562, a connecting plate 563, and a positioning component 564. Two sets of positioning devices 56 are provided, located on both sides of the transition channel 52 along the transport direction a.

[0079] Reference Figure 7 , Figure 9 and Figure 12 The fixed guide assembly 561 is connected to the transition channel 52 near the front end of the rotating module 5 in the transport direction a. The fixed guide assembly 561 includes a fixed box 5611, a positioning pin 5612, and guide wheels 5613. The fixed box 5611 is fixedly connected to the transition channel 52, and the fixed box 5611 has openings at both ends along the transport direction a. The positioning pin 5612 passes through the fixed box 5611. Four guide wheels 5613 are provided and are all located inside the fixed box 5611. The guide wheels 5613 are rotatably connected to the fixed box 5611. The multiple guide wheels 5613 are symmetrically arranged on both sides of the positioning pin 5612 and all roll against the positioning pin 5612 to limit the positioning pin 5612.

[0080] Reference Figure 9 and Figure 12 The positioning cylinder 562 is fixedly connected to the fixed box 5611. One end of the connecting plate 563 is hinged to the drive shaft of the positioning cylinder 562, and the other end is fixedly connected to the end of the positioning pin 5612 away from the parking channel 537.

[0081] Reference Figures 7 to 9 and Figure 12 Two sets of positioning components 564 are provided, located at both ends of the docking channel 537. Each positioning component 564 includes a positioning frame 5641 and positioning wheels 5642. The positioning frame 5641 is fixedly connected to the docking channel 537. Two positioning wheels 5642 are arranged vertically, each rotatably connected to the positioning frame 5641. When the docking channel 537 is aligned with the transition channel 52, a positioning pin 5612 is inserted between the two positioning wheels 5642, and both positioning wheels 5642 roll against the positioning pin 5612.

[0082] When the docking channel 537 and the transition channel 52 need to be aligned, the positioning cylinder 562 actuates, driving the positioning pin 5612 to move via the connecting plate 563. The positioning pin 5612, within the fixed box 5611, is limited by the rolling contact of multiple guide wheels 5613, and moves smoothly towards the positioning assembly 564. Once the docking channel 537 and the transition channel 52 are aligned, the positioning pin 5612 inserts between the two positioning wheels 5642 on the positioning frame 5641. The positioning wheels 5642 and the positioning pin 5612 roll and contact, completing the positioning and ensuring precise alignment between the track of the rotating module 5 and the accumulation rail 11. This ensures the tracks are on the same parallel and vertical lines, improving the stability and reliability of the system. Furthermore, regardless of whether the docking channel 537 is at 0 degrees or 180 degrees, precise alignment between the docking channel 537 and the transition channel 52 is maintained.

[0083] The combination logic of the components in the rotating module 5 is as follows: When the cargo trolley group 14 enters the parking channel 537, the anti-reverse device 54 limits its movement. The rotary motor 531 starts, driving the gear plate 534 to rotate through the reducer 532 and gear 533, which in turn drives the rotating drum 535 and rotating frame 536 to rotate 180 degrees, realizing the reversal of the cargo trolley group 14. After the reversal is completed, the anti-reverse device 55 is opened to release the anti-reverse state, and the cargo trolley group 14 can continue to run. This combination method realizes the 180-degree reversal of the cargo trolley group 14, improving the transportation efficiency of the production line.

[0084] Reference Figure 1 The traverse crane 6 is positioned between two production lines with opposite and non-intersecting transport directions (a), located behind the rotating device 53 along transport direction a. It is used to transfer the reversed cargo trolley group 14 to another production line in the opposite direction. The traverse crane 6 can be a self-propelled hoist trolley, possessing strong lifting capabilities. It can move back and forth between the two production lines, accurately transferring the reversed cargo trolley group 14 to the other production line.

[0085] Reference Figure 1 , Figure 2 , Figure 7 and Figure 13Both the cross module 3 and the rotation module 5 are equipped with corresponding detection modules 7 to detect the occupancy status of the cargo trolley group 14. The detection module 7 includes an occupancy bracket 71 and an occupancy detection switch 72. The occupancy bracket 71 is fixedly connected to the frame, and at least one occupancy detection switch 72 is provided and fixedly connected to the occupancy bracket 71. The occupancy detection switch 72 can be a photoelectric sensor, proximity sensor, or limit switch, etc., capable of monitoring the position and status of the cargo trolley group 14 in real time. When the cargo trolley group 14 enters or leaves, the detection module 7 sends a signal to the control module.

[0086] Both inlet ends of the cross module 3 are equipped with stoppers to pause the conveyor trolley 141, causing the cargo trolley group 14 to enter a temporary waiting state. The detection module 7 corresponding to the cross module 3 is located at the intersection of the first x-direction track and the second y-direction track. Only when the detection module 7 detects that no conveyor trolley 141 is occupying the cross module 3 can the cross chain 12 or the second pusher 34 drive the conveyor trolley 141 into the cross module 3.

[0087] The two rotating modules 5 corresponding to the cargo trolley group 14 form a group.
