Description

Technical Field

[0001] This application relates to the field of logistics and transportation technology, specifically to a tobacco leaf trolley suspension traction and transfer system. Background Technology

[0002] After grading, the tobacco leaves at the tobacco station's grading and purchasing line are currently transferred using two methods. One method is manual transfer. After grading, operators place the tobacco leaves into small carts filled with tobacco leaves, then push the carts dozens of meters away to a warehouse to retrieve, pack, and store the leaves. The empty carts are then pushed back to the grading room for another loading process. This process is repeated, resulting in high labor intensity and low efficiency due to the manual pushing of the carts. The other method uses a conveyor line. Because the tobacco boxes containing the leaves need to be manually placed onto the conveyor line, the boxes cannot be too large, and the loading weight is relatively small. Since the graded tobacco leaves need to be transported separately, frequent loading and unloading are required. Simultaneously, the storage area also needs to frequently remove tobacco boxes from the conveyor line. While the conveyor line method offers some mechanization, it suffers from drawbacks such as cumbersome operations and low transfer capacity. Summary of the Invention

[0003] The purpose of this application is to provide a tobacco leaf trolley suspension traction transfer system to solve the problems of high labor intensity and low work efficiency in manual transfer of tobacco leaf frames by pushing them back and forth, and the cumbersome operation and low transfer volume of conveyor lines.

[0004] To achieve the above objectives, this application provides a tobacco leaf trolley suspension traction and transfer system, comprising: a T-shaped bracket assembly, a track, a suspension chain, a transmission mechanism, a curve assembly, a swing-type tie rod, and a tobacco leaf trolley, wherein... The T-shaped bracket assembly includes a base bracket set at regular intervals, and a cantilever beam supporting both sides of the center is set above each base bracket. The center of all the cantilever beams is connected by a through frame. The rails are installed below both ends of the cantilever beam, and the rails are connected end to end to form a loop. The suspension chain is installed in the rail along the length of the rail. The tobacco cart is connected to the suspension chain via the swing-type pull rod; The curve assembly is located at the arc section of the track; The transmission mechanism is located above and connected to the suspension chain.

[0005] Optionally, the transmission mechanism includes a speed-regulating motor, a reducer, an output sprocket, a transmission chain, a bearing wheel assembly, and a track. The output end of the speed-regulating motor is connected to the reducer, the output sprocket is installed at the output end of the reducer, the output sprocket is connected to the bearing wheel assembly via the transmission chain, the track is installed on the bearing wheel assembly, and a tooth is provided below the track, which engages with the suspension chain.

[0006] Optionally, the curve assembly includes an end T-shaped bracket and a support frame. The lower ends of both ends of the end T-shaped bracket are connected to the track. The end T-shaped bracket and the support frame are connected by an elastic tensioning mechanism. The support frame is located on the side of the end T-shaped bracket away from the base bracket, and the lower end of the support frame is connected to the track.

[0007] Optionally, suspension plates are provided on links of the suspension chain at intervals, and the swing rod is provided below the suspension plates. The upper end of the swing rod is connected to the suspension plates on the suspension chain through a pin with a limiting plate.

[0008] Optionally, the lower end of the swing-type pull rod is connected to a press-type linkage hook, and the movable buckle at the lower end of the press-type linkage hook is connected to the connecting ring on the tobacco trolley handle.

[0012] The embodiments of this application have the following advantages: Compared to existing technologies, the above-mentioned technical solution provides a ground-based tobacco cart connected to an overhead suspension chain via a swing-type lever. The cart is transported by being dragged along the suspension chain, rather than being directly attached to the chain or a mechanism connected to it. In other words, the suspension chain pulls the ground-based tobacco cart along a traction route to complete the circular transport task. By dragging multiple carts at specific intervals below the conveyor chain, the continuous transport of various specifications and types of tobacco can be achieved. This solves the problems of high labor intensity and low efficiency in manual transport, where workers push tobacco carts back and forth, and the cumbersome operations and low transport capacity of conveyor lines.

[0018] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0019] This application provides a tobacco leaf trolley suspension traction and transfer system, referencing... Figures 1 to 10 ,include: The components include: 1. T-shaped support assembly; 2. track; 3. suspension chain; 4. transmission mechanism; 5. curve assembly; 6. swing-type tie rod; 7. tobacco leaf cart; and 9. (The remaining components are not translated as they are not part of the main text.) The T-shaped support assembly 1 includes a base support 10 arranged at regular intervals, and a cantilever beam 11 supporting both sides in the middle is provided above each base support 10. The middle of all the cantilever beams 11 are connected by a through frame 12.

[0020] The track 2, i.e. the running track 2 of the suspension chain 3, is set below both ends of the cantilever beam 11. The track 2 is connected end to end to form a ring. The suspension chain 3 is set in the track 2 along the length of the track 2.

[0021] The tobacco cart 9 is connected to the suspension chain 3 via the swing rod 7.

[0022] The curve component 5 is located at the arc section of the track 2.

[0023] The transmission mechanism 4 is located above the suspension chain 3 and is connected to the suspension chain 3.

[0024] Specifically, the tobacco leaf trolley 9 suspension traction and transfer system adopts a ring layout. A T-shaped bracket assembly 1 is installed on the center line of the ring. Tracks 2 are installed on the two cantilever arms of the T-shaped bracket assembly 1. Curving components 5 are installed on the semi-circular sections (arc sections) at both ends. The T-shaped bracket 14 at the end of the curving component 5 is connected to the support frame 13 through an elastic tensioning mechanism 6. The movement of the turning frame is achieved by adjusting the elastic tensioning mechanism 6, thereby achieving the tensioning of the suspension chain 3. The suspension chain 3 is installed in the entire track 2 and runs along the track 2. The suspension chain 3 is the carrier transported by the system.

[0025] refer to Figure 5 In some embodiments, the transmission mechanism includes a speed-regulating motor 20, a reducer, an output sprocket 21, a transmission chain 22, a bearing wheel assembly 23, and a track 24. The output end of the speed-regulating motor 20 is connected to the reducer, and the output sprocket 21 is provided at the output end of the reducer. The output sprocket 21 is connected to the bearing wheel assembly 23 through the transmission chain 22. The track 24 is provided on the bearing wheel assembly 23, and a tooth 25 is provided below the track 24. The tooth 25 engages with the suspension chain 3.

[0026] Specifically, the transmission mechanism 4 is the drive device of the suspension traction system. It operates through a speed regulating motor 20-reducer-transmission chain 22-bearing wheel set 23-drive track 24-suspension chain 3. When the track 24 rotates, it can drive the suspension chain 3 to move.

[0027] refer to Figure 6In some embodiments, the curve assembly 5 includes an end T-shaped bracket 14 and a support frame 13. The lower ends of the end T-shaped bracket 14 are connected to the track 2, and the end T-shaped bracket 14 supports the lower turning track 2. The end T-shaped bracket 14 and the support frame 13 are connected by an elastic tensioning mechanism 6. The turning frame (support frame 13) is moved by adjusting the elastic tensioning mechanism 6, thereby tensioning the suspension chain 3. The support frame 13 is located on the side of the end T-shaped bracket 14 away from the base bracket 10, and the lower part of the support frame 13 is connected to the track 2.

[0028] refer to Figure 3 and Figure 4 In some embodiments, suspension plates 19 are provided on the links of the suspension chain 3 at intervals, and the swing rod 7 is provided below the suspension plates 19. The upper end of the swing rod 7 is connected to the suspension plates 19 on the suspension chain 3 through a pin with a limiting plate. The swing rod 7 can swing unidirectionally within a certain range.

[0029] Specifically, the swing-type pull rod 7 is specifically designed for flexible towing connections. The upper end of the swing-type pull rod 7 is connected to the suspension plate 19 on the suspension chain 3 via a pin with a limiting plate, allowing the pull rod to swing open and close quantitatively in the opposite direction to the forward movement of the suspension chain 3. During continuous movement, the suspension chain 3 may experience slight forward and backward movement due to the chain's own tension or the difference in force experienced when turning compared to when moving straight. The swing-type pull rod 7, through its quantitative opening and closing with limiting, prevents excessive swing amplitude when it is suspended and moving synchronously with the suspension chain 3.

[0030] refer to Figure 5 In some embodiments, the lower end of the swing lever 7 is connected to a press-type linkage hook 8, and the movable buckle at the lower end of the press-type linkage hook 8 is connected to the connecting ring 18 on the handle of the tobacco cart 9, so as to realize quick connection and disconnection with the tobacco cart 9.

[0031] Specifically, a push-button linkage hook 8 is installed at the lower end of the swing-type pull rod 7. When the trolley needs to be hooked into the system, simply pull up the swing-type pull rod 7 and press the lower end of the hook onto the connecting ring 18 on the trolley handle for quick connection. When the trolley needs to be removed, due to the forward pulling force and inertia of the trolley, ordinary hooks are difficult to remove directly and quickly. The push-button linkage hook 8 has a two-way function; pressing the open / close button allows for quick disengagement, improving the convenience and safety of trolley removal.

[0032] refer to Figures 7 to 9In some embodiments, the main body of the tobacco trolley 9 is a welded steel body with wheels at the bottom. The tobacco trolley 9 is pulled and moved by the suspension chain 3. In order to meet the requirements of circular conveying, the tobacco trolley 9 must be able to achieve traction and turning. Therefore, in some embodiments, the two front wheels of the tobacco trolley 9 are universal wheels 16 and the two rear wheels are directional wheels 15.

[0033] In some embodiments, the tobacco cart 9 is provided with a card slot 17 for placing tobacco information cards. The card slot 17 can hold conventional handwritten paper cards or printed labels with QR codes.

[0034] Specifically, the tobacco cart 9 has a three-sided frame structure, with open outer sides for easy loading and unloading of tobacco leaves. Wheels are installed at the bottom, with the front two wheels being omnidirectional wheels 16 and the rear two wheels being directional wheels 15. This ensures the flexibility of the tobacco cart 9 when turning following the swing lever 7, and also prevents the tobacco cart 9 from tilting or swaying excessively during straight-line movement. A handle is provided at the front for easy manual pushing, and a connecting ring 18 is installed on the handle for connecting to the hook on the swing lever 7. The connecting ring 18 not only serves as a connection but also limits the connection between the cart and the hook, preventing the cart from swaying left and right during forward movement. The cart has a card slot 17 specifically for placing tobacco information cards, which are printed labels with QR codes.

[0035] Specifically, regarding the arrangement of the suspension traction spacing of the tobacco trolley 9 in the circular suspension traction transfer system, as mentioned above, the swing-type tie rods 7 in the system are arranged around the ring of the suspension chain 3. Each swing-type tie rod 7 is equivalent to an independent conveying position. Assuming the entire suspension conveying system has 20 sets of swing-type tie rods 7, that is, the system has 20 conveying positions. For the same circular suspension line, under the condition of the same maximum running speed of the suspension chain 3, the more independent conveying positions that can be reasonably arranged, the higher the operating efficiency of the system. However, the spacing between conveying positions cannot be reduced indiscriminately. It is necessary to consider not only the safe distance between two conveying positions, but also the convenience and safety of operators when picking up and placing the tobacco trolley 9 online, and the rationality of the swing-type tie rods 7 of the suspension chain 3 carrying the tobacco trolley 9 during turning movements. Therefore, referring to... Figure 10We assume the maximum speed of the conveyor chain is v = 18 m / min = 300 mm / s. Timing begins after the operator removes the tobacco cart 9 from the hook of the swing lever 7. The minimum time for manually pulling the cart and moving it away from the operating range below the suspension chain 3 is approximately 5 seconds. Allowing a safety reaction time of 1-3 seconds, each operation must be ≤8 seconds. Based on the above operating speed, the distance traveled by the next conveyor position in 8 seconds can be calculated to be 2.4 meters. Simultaneously, we assume the turning radius of the suspension chain 3 loop is 0.8 meters, then the circumference of the semi-circular loop is approximately 2.5 meters. Because the swing-type lever 7 and the tobacco cart 9 are connected by a movable connection, the movement path of the tobacco cart 9 when turning is not consistent with the loop of the suspension chain 3. The turning radius of the tobacco cart 9 will be smaller than the radius of the loop of the suspension chain 3. The turning radius of the tobacco cart 9 depends on the gap between the connecting ring 18 on the cart handle and the swing-type lever 7. For the cart's operational flexibility, we select the maximum angle between the connecting ring 18 on the cart and the swing-type lever 7 as 45 degrees. Assuming the cart's length is 'a' and its width is 'b', the difference in size between the front and rear when the cart turns is Δs = a * sin45°. The connection point of the connecting ring 18 and the cart... The maximum difference in inner edge dimension Δt = Δs + (b / 2) * cos45°. When a is 1130mm and b is 700mm, then Δt ≈ 1052mm. Therefore, the minimum straight-line distance between the two cars when turning should be greater than Δt + b / 2 + 100 = 1502mm. So, when the turning radius of the suspension chain 3 is 0.8 meters, a maximum of two cars can be arranged on the turning path, that is, one car at each end of the semicircular loop. The arc distance of the cars is exactly equal to the circumference of the semicircular arc s = πr = 2512mm. Therefore, the arrangement spacing of the swing rod 7 can be 2.5 meters.

[0036] In the tobacco leaf trolley 9 suspension traction transfer system, the tobacco leaf trolley 9 is connected to the upper suspension chain 3 via a swing-type tie rod 7. It is transported by being dragged along the suspension chain 3, rather than being directly mounted on the suspension chain 3 or any mechanism connected to it. In other words, the suspension chain 3 pulls the trolley on the ground along a traction route to complete the circular transport task. By suspending multiple trolleys at specific intervals below the suspension chain 3, the continuous transport of various specifications and types of tobacco leaves can be achieved. Since the tobacco leaf trolley 9 is not mounted, the suspension chain 3 only experiences the traction force on the trolley and not the weight of the trolley, thus greatly reducing the stress on the suspension chain 3. Simultaneously, the drive requirements of the entire suspension conveyor system are also significantly reduced. Compared to ordinary mounted suspension conveyors, this application has advantages such as a simple mounting bracket structure, low motor power requirements, and flexible loading and unloading, while also demonstrating advantages in safety, environmental protection, energy saving, and consumption reduction.

[0037] In some embodiments, it also includes: The electrical control system includes a main control cabinet and an auxiliary control box. The electrical control system is used to realize the automatic control, protection, monitoring, and measurement functions of the suspension traction system. The main control cabinet of the electrical control system is installed at the semi-circular end of one side of the grading zone of the suspension traction system's operating loop. The main control cabinet contains electrical components such as switches, power supplies, terminals, and modules. A touch screen is installed on the main control cabinet, and start, stop, and emergency stop buttons are installed on the main control cabinet door panel. Corresponding indicator lights and alarms are also designed and installed.

[0038] In some embodiments, an operating box is installed at the semi-circular end of the unloading position on the other side of the running loop. The operating box can also realize the start, stop and emergency stop control functions of the suspension traction system.

[0039] In some embodiments, multiple emergency stop button boxes are also provided around the operating loop to facilitate immediate shutdown of the system in case of an emergency.

[0040] In some embodiments, the auxiliary control box of the electrical control system includes a motor starter, a frequency converter, and a disconnect switch. Multiple detection elements or switches are also installed on the suspension traction system to perform monitoring and detection functions. Simultaneously, the electrical control program is also an important component, used to achieve electromechanical interlocking control.

[0041] Specifically, this application has the function of monitoring the system's operational flow. The tobacco leaf trolley 9 suspension traction transfer system adopts frequency conversion drive control, which can match and adjust the online conveying speed. When the system monitors frequent pick-up and drop-off operations, the conveying speed is automatically increased to improve transportation efficiency and meet the collaborative operation between the two workshops. Conversely, when there are no pick-up and drop-off operations for a long time, the system will enter standby mode, that is, the suspension chain will run at the minimum speed set by the system.

[0042] This application also features a human body monitoring and speed control function. A human body detection switch is installed on the circular track 2. When the human body detection switch detects a human body approaching, it feeds back the detection information to the suspended conveyor control system. The control system then controls the drive system to intelligently reduce speed, making it easier for workers to pick up and put down the tobacco leaf trolley 9 and improving the safety of the operation.

[0043] In summary, compared with existing technologies, the above-mentioned technical solution provides a ground-based tobacco cart connected to an overhead suspension chain via a swing-type lever. The cart is transported by being dragged along the suspension chain, rather than being directly attached to the suspension chain or a mechanism connected to it. In other words, the suspension chain pulls the ground-based tobacco cart along a traction route to complete the circular transport task. By dragging multiple carts at specific intervals below the conveyor chain, the continuous transport of various specifications and types of tobacco can be achieved. This solves the problems of high labor intensity and low efficiency in manual transport, where workers push tobacco carts back and forth, and the cumbersome operations and low transport capacity of conveyor lines.

Therefore, unless explicitly stated otherwise, each disclosed feature is merely one example of a set of equivalent or similar features.

For example, two consecutive functions and steps may actually be executed or implemented substantially in parallel, and they may sometimes be executed or implemented in reverse order, depending on the functions involved.
