Description

Technical Field

[0001] The invention relates to a processing system, in particular to a processing system for processing strip materials. Background Art

[0002] The preparation process of tobacco is relatively complicated. After the tobacco leaves are harvested, they need to be processed in different ways according to their characteristics and processing traditions. The purpose is to remove the green and excess moisture of the tobacco leaves for preservation; during the preparation process, the internal part is initially saccharified and matured to prepare for the complicated processing procedures later. There are several ways to process tobacco leaves: air-drying treatment method, the tobacco processed by this method is the most mellow. The tobacco leaves are first naturally air-dried in an open farm shed, and then placed in large sacks for fermentation; fermentation treatment changes the chemical composition of tobacco, making the flavor softer and reducing its nicotine content; sun-drying treatment method, tobacco leaves are fixed on rings and hung on the walls of the farm shed, using sunlight and natural wind to dry and mature. Almost all oriental tobacco is processed by this method; hot air pipe treatment method, after the tobacco leaves are harvested, they are immediately placed in a closed farm shed, and the hot air convection generated by the hot air pipe heating is used to dry the tobacco leaves. Due to the rapid drying process, the tobacco leaves turn yellow, and this method is often used to process blended tobacco; the open flame baking method, the tobacco processed by this method is the most intense. The tobacco leaves are hung over the open flame, and the thick smoke generated is used to smoke the tobacco leaves, giving the tobacco a unique "smoky" flavor.

[0003] In order to standardize the operation and improve work efficiency, the existing tobacco leaves need to be cured in a tobacco curing room, and pairs of shelves are arranged at the same height in the tobacco curing room. The tobacco leaves are clamped together by clamping rods in parallel. After the tobacco leaves are loaded into the tobacco curing room, the clamping rods are straddled to a pair of shelves, and the ends of the clamping rods can be slidably placed on the shelves. When loading tobacco leaves into the tobacco curing room, the clamping rods with tobacco leaves clamped on the shelves are pushed from the outside to the inside in sequence, so that the clamping rods gradually slide inward along the shelves, and the clamping rods are arranged in parallel on the shelves. A heating device is provided in the tobacco curing room, and the tobacco leaves are cured by the heating device. Under the existing technical conditions, before the tobacco leaves are sent to the tobacco curing room, they need to be clamped manually in the form of clamping rods. After the tobacco leaves are cured, the materials are also discharged from the tobacco curing room manually.

[0004] The existing method of processing tobacco leaves has high labor intensity and low operating efficiency and cannot meet production needs well. Summary of the invention

[0007] This processing system is generally used to bake tobacco leaves in strips. During the processing of tobacco leaves, the tobacco leaves need to be sorted and then clamped by comb-type clamping rods, which are clamped to the roots of the tobacco leaves. When the tobacco leaves flow in this processing system, the tobacco leaves are generally in a state with the root facing up and the tail facing down. The clamping rods are placed on the corresponding structure, and the clamping rods drive the tobacco leaves to flow in the processing system. During the circulation of tobacco leaves, on a certain device, multiple clamping rods are generally arranged in parallel to form a set, and then the whole set is transported and circulated.

[0008] Furthermore, a pushing device is provided on the outer side of the feeding end of the loading frame, and the pushing device is used to push the clamping rod with the material clamped to the feeding end of the loading frame. The displacement of the clamping rod is achieved by pushing of the pushing device, so that the clamping rod can smoothly enter the loading frame, and the loading drive belt can push the clamping rod, so that multiple clamping rods can be arranged on the loading frame in parallel at the same time.

[0009] Furthermore, the structure of the pushing device includes a pushing member and a pushing power mechanism connected together, and the pushing member is in conflict with the clamping rod in a manner parallel to the clamping rod. The pushing member can be a plurality of top rods perpendicular to the clamping rod. Now, the pushing member is designed to be in conflict with the clamping rod in a manner parallel to the clamping rod, which can effectively simplify the structure of the pushing member, ensure the pushing stability of the clamping rod by the pushing member, and the weight of the pushing member can be made lighter.

[0010] Furthermore, the pusher is provided with a resistance member extending downward, and the resistance member is used to resist the material on the clamping rod. The resistance member pushes the tobacco leaves during the circulation process by resisting the tobacco leaves, so that the position consistency between the tobacco leaves and the clamping rod is good, so as to avoid the movement lag of the tobacco leaves due to inertia, and improve the position stability of the tobacco leaves during the circulation process.

[0011] Furthermore, the pusher is a plate-shaped body, the abutment is a sheet-shaped body, and several abutments are arranged at intervals along the length direction of the pusher. Such a pusher and abutment sheet make the movable parts of the pusher device light in weight, and on the basis of satisfying the requirement of stable pushing of tobacco leaves and the clamping rod, it is also convenient to control the movement of the pusher.

[0012] Furthermore, the shelf rod, loading rack and / or unloading rack are of split structure, including two clamping plates arranged in parallel, an installation cavity is formed between the two clamping plates, a mounting seat is respectively provided at both ends of the installation cavity, a transmission wheel is rotatably provided on the mounting seat, a strip-shaped upper support body and a lower support body are provided in the installation cavity, the upper support body is located on the upper side of the lower support body, and the two clamping plates are respectively fixed on the opposite side surfaces of the upper support body and the lower support body. The shelf rod, loading rack and unloading rack of this structure are easy to install, especially the foundation of their identical structures, which is also convenient for the preparation of the entire processing system. Moreover, the components of this structure are also convenient for transmission connection with the driving belts to which they belong, and the support body can provide stable support for the driving belt, which is convenient for the driving belt to push the movement of the clamp rod.

[0013] Furthermore, a folded edge extending toward the other splint is integrally formed at the bottom end of one of the splints, and the lower support body is connected to the folded edge. This not only facilitates the installation of the lower support body, but also effectively ensures the connection firmness between the two splints, so that the overall connection strength is guaranteed.

[0014] Further, the cross-section of the upper support body is in a "mountain" shape, and the cross-section of the lower support body is in a "convex" shape. The support body with such a structure can well adapt to the support of the chain-type drive belt, so that the position stability of the drive belt during movement is good.

[0015] Further, a limiting rod is provided on the unloading support. The limiting rod is arranged in the vertical direction, and the lower end of the limiting rod is bent upward. The lower end of the limiting rod is used to block the unloading rack. By setting the limiting rod, the downward travel distance of the unloading rack is limited, so as to prevent the tobacco leaves from falling due to excessive downward travel of the unloading rack, and the production safety during unloading is improved. By limiting the downward movement of the unloading rack through the limiting rod, a stable unloading position can be formed on the unloading device, so that it is convenient for the operator to take out the clamping rod with the processed material hung on it from the unloading rack, and the operation stability is good.

[0016] Further, the unloading rack is connected to the unloading lifting mechanism through a connecting piece. A guide plate is provided on the unloading lifting mechanism below the connecting piece. The cross-section of the guide plate is in a "匚" shape. A guide groove for inserting the lower end of the limiting rod is formed on the guide plate. The lower end of the limiting rod abuts against the connecting piece in the guide groove, so as to realize the limitation of the unloading rack. By setting the guide plate, the stable abutment between the lower end of the limiting rod and the connecting piece is realized, so that the action stability of the limiting rod on the unloading rack is good, and the stable limitation of the limiting rod on the downward movement of the unloading rack is ensured.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In this processing system, by providing a processing bin, a loading device and a unloading device, the automatic transfer and processing of materials are realized. During the transfer process of the materials, the human participation is small, which can effectively save the physical strength of the operators and has high operation efficiency. A placing rod is provided in the processing bin. By driving the drive belt, the clamping rod with the material hung on it is pushed to move forward on the placing rod, so that the material can automatically move deep into the processing bin on the placing rod to complete feeding, or move towards the outlet end of the processing bin on the placing rod to complete unloading. The automation degree is high, and manual feeding or unloading is not required, so that the operator can stay away from the harsh conditions in the processing bin and can provide protection for the operator. The loading device has a loading rack. Multiple clamping rods with materials hung on them can be arranged side by side on the loading rack. The loading rack can realize the side-by-side loading of multiple clamping rods at one time, and the operation efficiency is high; and by driving the drive belt to push the clamping rod with the material hung on it to be arranged on the loading rack, the operation speed is fast, and basically no manual assistance is required to complete, so that the labor intensity is low. The unloading device is provided with an unloading rack. The structure of the unloading rack is similar to that of the loading rack, and it also has the advantages of fast loading speed and low labor intensity. Description of the Drawings

DETAILED DESCRIPTION

[0027] Combined with the drawings in the specification, the clamping and hanging strip material processing system is used to process materials, and in the process of processing materials, the material flow can also be automatically realized. The following takes the processing of tobacco leaves 1 as an example to further illustrate the processing system. When processing tobacco leaves 1, a comb-type clamping rod 13 is required to clamp the tobacco leaves 1, so that the tobacco leaves 1 are always in a state of being clamped and hung by the clamping rod 13.

[0028] See also Figure 6The structure of the processing system includes a processing bin 20, which is used for processing tobacco leaves 1. The processing bin 20 is generally called a flue-curing room. A plurality of shelf rods 21 are fixedly connected to the two opposite inner walls of the processing bin 20. The shelf rods 21 are arranged in a horizontal direction. These shelf rods 21 are arranged in pairs on the two inner walls. Two shelf rods 21 in a pair of shelf rods 21 are arranged at the same height on the two inner walls. The two ends of the clamping rod 13 clamped with tobacco leaves 1 are respectively placed on the pair of shelf rods 21. A plurality of resting positions for the clamping rod 13 to rest are formed on the shelf rod 21, and these resting positions are arranged in the length direction of the shelf rod 21. The resting position is a spatial concept. The resting position does not have a specific fixed position, but only exists on the shelf rod 21. After the clamping rod 13 is placed on the shelf rod 21, the position where the clamping rod 13 is located is the resting position. A processing drive belt is arranged in the processing bin 20, and the processing drive belt is arranged along the length direction of the shelf rod 21. The processing drive belt is used to drive the clamping rod 13 with tobacco leaves 1 to move in the length direction of the shelf rod 21, so as to realize the parallel arrangement of the clamping rod 13 with tobacco leaves 1 on the shelf rod 21, or to make the clamping rod 13 with tobacco leaves 1 discharge toward the inlet end of the shelf rod 21.

[0029] The processing drive belt is generally a drive chain 101, which is directly arranged on the shelf rod 21, and the shelf rod 21 provides support for the drive chain 101. At this time, the drive chain extends to the upper side of the shelf rod 21, and the end of the clamping rod 13 with the tobacco leaves 1 clamped is directly placed on the drive chain 101. A concave structure can be set at the end of the clamping rod 13 to match the drive chain 101, so that the drive chain 101 can directly move with the clamping rod 13; the drive chain 101 can also directly drive the clamping rod 13 to move together through static friction. The processing drive belt can also be a V-belt or a belt. At this time, a number of extended drive structures are arranged at equal intervals on the processing drive belt, and the clamping rod 13 with the tobacco leaves 1 clamped can be moved on the shelf rod 21 through the conflict between the drive structure and the clamping rod 13.

[0030] See also Figure 1 , 2 3. The processing system also includes a loading device. A workbench 7 is also provided on the upstream side of the loading device. The operator sits on the workbench 7. The operator arranges the tobacco leaves 1 on the workbench 7 and clamps the roots of the tobacco leaves 1 with a clamping rod 13 by applying pressure from a cylinder. The clamping rod 13 is clamped on the free end of the swing frame 2. The swing frame 2 swings under the action of the swing cylinder 4 and is used to transfer the tobacco leaves 1 from the clamping position to the loading position 8. When the free end of the swing frame 2 swings to the loading position 8, the clamping structure at the lower end of the swing frame 2 will open and release the clamping rod 13 to the loading position 8. The loading device is at the loading position 8 and is used to transport the clamping rod 13 with the tobacco leaves 1 clamped thereon to the position of the processing bin 20, so as to load the tobacco leaves 1 into the processing bin 20.

[0031] The structure of the loading device includes a loading bracket 3, the upper end of the above-mentioned swing frame 2 is hinged on the loading bracket 3, and the swing cylinder 4 is also movably arranged on the loading bracket 3, and the swing cylinder 4 is located on the outside of the swing frame 2. A lifting space is formed in the loading bracket 3, and the loading frame 5 is movably arranged in the lifting space. There are two loading racks 5, and the two loading racks 5 are arranged in parallel and spaced apart. The clamping rod 13 with the tobacco leaves 1 is straddled on the two loading racks 5. The loading rack 5 has a plurality of resting positions for the clamping rod 13 to rest, and the concept of these resting positions is the same as the resting positions on the aforementioned shelf rod 21. A loading lifting mechanism is provided on the loading bracket 3, and the loading lifting mechanism can be a screw mechanism or a cylinder mechanism. As shown in the figure, the lifting mechanism includes a loading chain 6 arranged on the loading bracket 3, and the loading chain 6 is connected to the loading rack 5. Corresponding to the two loading racks 5, there are two loading chains 6. A transmission shaft is provided at the bottom end of the loading rack 3. The transmission shaft is synchronously driven with the two loading chains 6. The loading motor is connected to the transmission shaft. Driven by the loading motor, the two loading racks 5 are synchronously lifted and lowered. Position sensors are provided on the loading rack 3 corresponding to the heights of the shelf rods 21. The loading motors are controlled by the position sensors so that the loading racks 5 can adapt to the docking requirements of the shelf rods 21 of different heights. The lifting height of the loading rack 5 can also be determined by the working time of the loading motor, so as to achieve the docking of the loading rack 5 with the corresponding shelf rods 21. A walking wheel is also provided at the bottom end of the loading rack 3, so that the loading device can be pushed to load tobacco leaves 1 into different processing bins 20.

[0032] A loading drive belt may be provided at the middle of the two loading racks 5 to drive the clamping rod 13 clamped with tobacco leaves 1 to move from the feeding end of the loading rack 5 to the discharging end, so that multiple clamping rods 13 clamped with tobacco leaves 1 are arranged in parallel on the loading rack 5, and when tobacco leaves 1 are loaded into the processing bin 20, the clamping rod 13 clamped with tobacco leaves 1 is discharged from the discharging end of the loading rack 5 to the inlet end of the shelf rod 21. At this time, the loading drive belt is provided along the length direction of the loading rack 5, and a plurality of protruding drive structures are provided on the loading drive belt, and the drive structures push the clamping rod 13 by contacting with the clamping rod 13. Figure 8 As shown in FIG. 1 , the loading drive belt is a drive chain 101 , which is directly disposed on the loading frame 5 . The loading frame 5 provides support for the drive chain 101 , and the end of the clamping rod 13 clamping the tobacco leaves 1 is directly placed on the drive chain 101 .

[0033] After the tobacco leaves 1 are processed, they need to be unloaded. When unloading the tobacco leaves 1, the loading and unloading of the tobacco leaves 1 is also achieved by mechanical devices. Specifically, the processed tobacco leaves 1 in the processing bin 20 are unloaded by a unloading device. The structure of the unloading device includes a three-dimensional frame-type unloading bracket 14, and a lifting space is formed inside the unloading bracket 14. The unloading rack 16 is movably arranged at the position of the lifting space. The unloading rack 16 is similar to the structure of the loading rack 5, and the whole forms a rod-shaped structure. There are also two unloading racks 16, and the two unloading racks 16 are arranged in parallel and spaced apart. There are a number of placement positions on the two unloading racks 16 for the clamping rods 13 with tobacco leaves 1 clamped thereon to rest. The clamping rods 13 are placed on the two unloading racks 16 in a straddling manner. In the actual application process, multiple clamping rods 13 with materials clamped thereon will be placed on the unloading rack 16 in parallel at the same time, and the unloading racks 16 will unload them at the same time. These clamping rods 13 will automatically enter the unloading rack 16 from the shelf rods 21 in the processing bin 20, and the driving chain 101 on the shelf rods 21 in the processing bin 20 will move in the opposite direction, thereby driving the clamping rods 13 to move toward the outlet end of the shelf rods 21. The unloading driving belt is arranged along the length direction of the unloading rack 16, and the unloading driving belt is used to drive the clamping rods 13 clamped with tobacco leaves 1 to move in the length direction of the unloading rack 16, so that multiple clamping rods 13 clamped with processed tobacco leaves 1 are arranged in parallel on the unloading rack 16. The unloading driving belt is a driving chain 101, and the driving chain 101 is directly arranged on the unloading rack 16. The clamping rods 13 entering the unloading rack 16 are directly placed on the driving chain 101, and the driving chain 101 drives the clamping rods 13 to move, so that the clamping rods 13 clamped with processed tobacco leaves 1 coming out of the shelf rods 21 are smoothly arranged on the unloading rack 16. Since the processing bin 20 adopts a multi-layer structure, that is, the shelf rods 21 are arranged in multiple layers in the height direction, when unloading, the tobacco leaves 1 are generally unloaded layer by layer. A unloading lifting mechanism is provided on the unloading bracket 14, and the unloading lifting mechanism is connected to the unloading frame 16 by transmission. The unloading lifting mechanism is used to drive the unloading frame 16 to rise and fall on the unloading bracket 14, so that the unloading frame 16 can adapt to the docking requirements of the shelf rods 21 of different heights. As shown in the figure, the unloading lifting mechanism is a chain-type unloading chain 15, corresponding to two unloading frames 16, and the unloading chain 15 is also two, and one unloading chain 15 is connected to one unloading frame 16. A unloading motor is provided at the bottom of the unloading bracket 14, and the unloading motor is connected to the transmission shaft by transmission, and the two unloading chains 15 are connected to the transmission shaft. After the unloading motor is started, the two unloading frames 16 will be raised and lowered synchronously.

[0034] A walking wheel is provided at the bottom end of the unloading bracket 14, and the entire unloading device can be moved by pushing, so that the position can be moved during the unloading process, reducing the carrying distance of the operator.

[0035] In order to facilitate the clamping rod 13 with tobacco leaves 1 to enter the loading rack 5 smoothly, a pushing device is provided on the loading rack 3, and the pushing device is located outside the feeding end of the loading rack 5. The free end of the swing rack 2 moves to the loading position 8, and the loading rack 5 is flush with the loading position 8 at this time. The swing rack 2 releases the clamping rod 13 with tobacco leaves 1, and the pushing device pushes the clamping rod 13 with tobacco leaves 1 toward the feeding end of the loading rack 5, so that the clamping rod 13 can enter the loading rack 5 smoothly. The structure of the pushing device includes a pushing member 10 and a pushing power mechanism connected together. The pushing power mechanism is generally a pushing cylinder 12. The pushing member 10 pushes the clamping rod 13 in a way that it conflicts with the clamping rod 13. A vertical plate 9 is welded and fixed on the loading rack 3 in a vertical manner, and the pushing cylinder 12 is fixed on the vertical plate 9 in a horizontal manner. The pushing member 10 is connected to the outer end of the piston rod of the pushing cylinder 12. In order to improve the stability of the pusher 10 during movement, a mutually sleeved columnar guide structure is provided between the vertical plate 9 and the pusher 10. In order to adapt to the presence of the tobacco leaf 1 on the clamping rod 13, the pusher 10 is provided with a resistance member 11 extending downward. When operating, the pusher 10 is in contact with the clamping rod 13, and the resistance member 11 is in contact with the tobacco leaf 1 on the clamping rod 13. The pusher 10 is a plate-like body, and the cross section of the pusher 10 is L-shaped. When pushing, the pusher 10 contacts the side and bottom surfaces of the clamping rod 13. There is generally one pusher 10, and the length of the pusher 10 is close to the length of the clamping rod 13, and the setting direction of the pusher 10 is perpendicular to the moving direction of the clamping rod 13. The resistance member 11 is a sheet-like body, and several resistance members 11 are arranged at intervals in the length direction of the pusher 10.

[0036] The shelf rod 21, the loading rack 5, and the unloading rack 16 are independent functional units, and the structures of the three are similar, generally split structures, and they are all arranged in pairs. Taking an independent functional unit as an example, its structure generally includes two clamping plates 103 arranged in parallel, and the clamping plates 103 are arranged vertically. An installation cavity is formed between the two clamping plates 103, and a mounting seat 109 is respectively provided at both ends of the installation cavity. A sprocket is rotatably provided on each mounting seat 109. The driving chain 101 is transmission-connected to the two sprockets of a functional unit. The driving chains 101 on the two functional units are arranged side by side, and the two sprockets on the same side of the two functional units are circumferentially fixedly sleeved on a transmission shaft. The two sprockets serve as driving wheels, and the transmission shaft is connected to the driving motor 105. After the driving motor 105 is started, it will cause the driving chain 101 to move, and drive the clamping rod 13 placed thereon to move, so as to achieve the arrangement or movement of the clamping rod 13 on the shelf rod 21, the loading rack 5 and the unloading rack 16. In order to ensure the structural strength of the functional unit and the stable support of the driving chain 101, a strip-shaped upper support body 102 and a lower support body 104 are provided in the installation cavity. The upper support body 102 is located on the upper side of the lower support body 104, and the two clamping plates 103 are respectively fixed on the opposite side surfaces of the upper support body 102 and the lower support body 104. After the drive chain 101 is installed in place, the drive chain 101 is connected between the upper support body 102 and the lower support body 104, wherein the upper support body 102 supports the drive chain 101 from the back side of the drive chain 101, so that the drive chain 101 remains extended to the upper side of the functional unit, and the clamping rod 13 is directly placed on the drive chain 101; the lower support body 104 supports the drive chain 101 from the bottom side of the drive chain 101. In order to facilitate the installation of the lower support body 104, one of the two clamping plates 103 of a functional unit has a folded edge 1031 extending toward the other clamping plate 103 formed integrally at the bottom end thereof, and the lower support body 104 is supported and connected to the folded edge 1031. In order to adapt to the structure of the driving chain 101, the cross section of the upper support body 102 is in the shape of a "mountain", and the cross section of the lower support body 104 is in the shape of a "convex", so that the driving chain 101 can fit well with the lower support body 104. If the length of the functional unit is long, in order to ensure the strength of the functional unit itself, a number of spacers 108 are further arranged between the two clamping plates 103, and the two clamping plates 103 are fixed to the opposite side surfaces of the spacer 108 by tightening screws.

[0037] Figure 6 It is a simplified drawing of the processing bin 20. In actual application, the processing bin 20 is a brick-concrete structure, and the shelf rod 21 is fixed on the inner wall surface of the processing bin 20. The loading rack 5 and the unloading rack 16 are connected to the corresponding chains through certain specific structures. Figure 8As shown, a connecting rod 106 and a connecting frame 107 are further provided on the functional unit (the functional unit only represents the loading rack 5 and the unloading rack 16). Among them, the connecting rod 106 is rod-shaped and the connecting rod 106 is an aluminum profile; the connecting frame 107 is a trough-shaped body, and the cross-section of the connecting piece is in a U shape. Corresponding to the paired loading rack 5 and unloading rack 16, the connecting rod 106 and the connecting frame 107 are both provided in pairs. Among them, the openings of the paired connecting frames 107 face each other, and the inner cavity of the connecting frame 107 is for the end of the clamping rod 13 to slide and insert.

[0038] In order to prevent the unloading rack 16 from falling during the lifting process and to form a stable unloading position on the lower side of the unloading support 14, a limiting rod 17 is provided on the unloading support 14. The limiting rod 17 is arranged in the vertical direction and is welded to the unloading support 14 by fitting. The lower end of the limiting rod 17 bends upward, and the lower end of the limiting rod 17 is used to block the unloading rack 16. Specifically, the unloading rack 16 is connected to the unloading chain 15 through a connecting piece 19. A guide plate 18 is provided on the unloading chain 15 below the connecting piece 19. The guide plate 18 is fixedly connected to the unloading chain 15 through a hoop. The cross-section of the guide plate 18 is in a U shape, and the guide plate 18 opens in the direction of the limiting rod 17. A guide groove for the lower end of the limiting rod 17 to insert is formed on the guide plate 18. After the unloading rack 16 moves downward in place, the lower end of the limiting rod 17 will be inserted into the guide groove, so that the limiting rod 17 will contact the connecting piece 19 in the guide groove, thereby realizing the limitation of the unloading rack 16.

[0039] When the processing system is working, the operator sits in front of the workbench 7, sorts out the messy tobacco leaves 1, and uses the cylinder top pressure method to realize the split clamping rod 13 to clamp the roots of the tobacco leaves 1. The clamping rod 13 clamped with tobacco leaves 1 is locked by the lock at the lower end of the swing frame 2. Driven by the swing cylinder 4, the lower end of the swing frame 2 moves toward the loading position 8. After the lower end of the swing frame 2 moves to the position, the lock is opened and the clamping rod 13 is released at the lower end of the swing frame 2. The push cylinder 12 is started, and the push cylinder 12 drives the push member 10 and the resistance member 11 to move toward the clamping rod 13 at the loading position 8, so that the clamping rod 13 moves to the loading frame 5 parked at the loading position 8. The driving motor 105 on the loading rack 5 is started, and the driving chain 101 is moved, so that the clamping rod 13 on the loading rack 5 moves from the feeding end to the discharging end. The driving motor 105 is generally a stepping motor, which adopts a stepping working mode, that is, one operation will cause the driving chain 101 to move a unit distance and then stop, and then wait for the next clamping rod 13 with tobacco leaves 1 to enter the loading rack 5. After the clamping rod 13 carried by the loading rack 5 reaches the target number, the loading motor is started, and the loading chain 6 drives the loading rack 5 and the clamping rod 13 and tobacco leaves 1 thereon to rise or fall, so that the loading rack 5 stays at the corresponding height and connects with the target shelf rod 21. After the two are connected, the driving chain 101 on the shelf rod 21 moves driven by the power mechanism, and the driving chain 101 on the loading rack 5 prompts the clamping rod 13 to move toward the discharging end of the loading rack 5 and finally enter the target shelf rod 21. After the clamping rod 13 on the loading rack 5 is loaded into the processing bin 20, the driving motor 105 on the loading rack 5 stops working, and the power mechanism corresponding to the shelf rod 21 also stops working, and the clamping rod 13 on the shelf rod 21 is in a static state waiting for the arrival of the next batch of clamping rods 13. In this way, the loading device continues to load the clamping rod 13 with tobacco leaves 1 onto the shelf rod 21 until the loading amount of the clamping rod 13 on a certain layer of shelf rods 21 reaches the target number. Whether the driving motor 105 on the loading rack 5 and the unloading rack 16 is working or not, and whether the power mechanism corresponding to the shelf rod 21 is working or not, can be controlled by a PLC program, or by setting some sensors to realize the control of the power source of these movable parts. After the processing bin 20 is fully loaded, the baking device in the processing bin 20 is started, so that the tobacco leaves 1 clamped and hung on the clamping rod 13 are baked.After the tobacco leaves 1 are roasted, the door of the processing bin 20 is opened, the unloading device is pushed to the door position of the processing bin 20, and the lifting mechanism on the unloading device is started, so that the unloading rack 16 reaches the corresponding height and connects with the target shelf rod 21, and the power mechanism corresponding to the shelf rod 21 is started in reverse, and the clamping rod 13 on the shelf rod 21 moves toward the inlet end of the shelf rod 21. At the same time, the driving motor 105 on the unloading rack 16 is started in the forward direction, so that the driving chain 101 receives the clamping rod 13 on the shelf rod 21. After the clamping rod 13 on the unloading rack 16 is full, the lifting mechanism on the unloading device is started to make the unloading rack 16 descend. When it descends to the lowest position, the limit rod 17 conflicts with the connecting piece 19 on the unloading rack 16, so that the unloading rack 16 is stably in the unloading position. The driving motor 105 on the unloading rack 16 is started in reverse, and the clamping rod 13 is moved toward the outlet end of the unloading rack 16 by driving the chain 101. The operator stands at the outlet end of the unloading rack 16 and unloads the processed tobacco leaves 1 and the clamping rod 13 from the unloading rack 16. After all the clamping rods 13 on the unloading rack 16 are unloaded, the unloading rack 16 is driven by the lifting mechanism to rise to the position of the target shelf rod 21, so as to continuously unload the tobacco leaves 1 in the processing bin 20.

[0040] The docking involved means that the unloading rack 16 and the loading rack 5 are at the same height as the target shelf 21. They can be docked by setting a certain matching structure, or they can just be at the same height, just close to each other without direct contact. For height control, the height of the unloading rack 16 and the loading rack 5 can be sensed by setting a sensor on the processing bin 20.
