Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a flexible chain plate conveyor for a buffer zone. Background Art

[0002] In modern industrial production, with the continuous improvement of automation and the increasing expansion of production scale, the efficiency, stability, and flexibility of the material conveying link have become key factors affecting production efficiency and cost. As a common material conveying device, flexible chain plate conveyors are widely used in many industries such as food, electronics, and medicine. However, traditional flexible chain plate conveyors have exposed many problems in actual use and are difficult to meet the current complex and changeable production requirements.

[0003] For example:

[0004] Traditional flexible chain plate conveyors have weak capabilities in dealing with emergencies. When a certain conveying track fails, it is often unable to quickly switch to other tracks to continue conveying materials, resulting in the entire production line being forced to stop, causing production stagnation and economic losses;

[0005] Each conveying track needs to be equipped with a separate motor, which not only greatly increases the procurement cost of the equipment but also makes the overall volume of the equipment large, occupying too much production space. Too many motors will also increase energy consumption and maintenance workload, reducing the economy and stability of production.

[0006] Therefore, a flexible chain plate conveyor for a buffer zone is proposed. Summary of the Invention

[0031] Compared with the prior art, the present invention has the following beneficial effects:

The upper limit plate and the side limit plate on the mounting bracket are detachably installed by bolts, facilitating the installation and adjustment of the drive unit;

[0037] The anti-detachment mechanism set at the discharge port of the buffer module can block the materials buffered on the buffer module, preventing the materials from falling from the discharge port when they are not received by the confluence module, ensuring the stability of material conveying;

[0038] The first guide wheel and the second guide wheel set at the bottom of one end of the buffer module close to the drive mechanism enable the bottom of the flexible chain plate to rollingly contact the fixed bracket and the second guide wheel, and part of it is arranged in a U-shaped overhang, which helps to buffer and adjust the chain plate tension and improve the stability of conveying.

[0073] Through the modular design of shunting, caching, and confluence, materials can be flexibly distributed and transported according to production requirements, improving the flexibility and stability of production. The setting of the anti-drop mechanism avoids the dropping of materials, reduces the risk of material loss and equipment failure. During operation, the materials are first distributed to the flexible chain plates 102 of different buffer support frames 101 through the shunting module 2 for caching. The driving mechanism 4 drives the flexible chain plates 102 to rotate, realizing the transportation of materials within the caching module 1. When it is necessary to send the materials to the production line, the confluence module 3 takes out the materials on the buffer support frame 101 and conveys them to the production line feeding port in a confluent manner. During this process, the anti-drop mechanism 5 always blocks the materials to prevent them from dropping when not received by the confluence module 3.

The lower flexible chain plate 102 is located between the lower track 10122 and the upper track 10123, and the upper flexible chain plate 102 is located above the upper track 10123.

[0075] The design of the quick-release component 1012 makes the installation, disassembly, and maintenance of the buffer support frame 101 more convenient and fast. A quick-release component 1012 is arranged at intervals on the fixed bracket 1011, facilitating the threading of the flexible chain plate 102, so as to facilitate the later maintenance and replacement of the flexible chain plate 102, saving time and labor costs.

One end of the fixed shunt conveyor belt 202 away from the buffer module 1 is provided with a diversion port 207 communicated with the movable shunt conveyor belt 203.

[0080] The confluence module 3 can flexibly collect materials from different buffer support frames 101 and convey them in a confluence manner to the feeding port of the production line. The settings of the second linear module 304 and the guide block 306 ensure the high efficiency and accuracy of material confluence and improve the overall efficiency of material conveying.

[0081] During use, the fourth motor 3021 drives the fixed confluence conveyor belt 302 to rotate to receive the materials from the outermost buffer support frame 101 of the buffer module 1. When it is necessary to collect materials from other buffer support frames 101, the second linear module 304 drives the movable confluence conveyor belt 303 to move along the second guide rail 305 so that its feed inlet is communicated with the discharge outlet of the target buffer support frame 101. The fifth motor 3031 drives the movable confluence conveyor belt 303 to rotate to convey the materials to the fixed confluence conveyor belt 302, and the guide block 306 guides the materials to smoothly enter the fixed confluence conveyor belt 302 to achieve material confluence.

[0082] In this embodiment, the driving mechanism 4 includes a base 401, a mounting frame 402, and a driving assembly 403. There are multiple mounting frames 402, and all of the multiple mounting frames 402 are fixedly installed on the base 401; the driving assembly 403 includes multiple driving units 4031 and a driving motor 4032. The driving units 4031 are detachably installed on the corresponding mounting frames 402. The driving unit 4031 includes a transmission shaft 40311, on which an electromagnetic clutch 40312 is fixedly installed. A driving sprocket 40313 is rotatably installed on the transmission shaft 40311 through a bearing. Chain coupling sprockets 40314 are fixedly installed at both ends of the transmission shaft 40311. Adjacent transmission shafts 40311 are connected by chain couplings for transmission. The rotating shaft of the driving motor 4032 is fixedly connected to one end of the outermost transmission shaft 40311. The flexible chain plate 102 meshes with the driving sprocket 40313; after the electromagnetic clutch 40312 is powered on, the friction plate on the electromagnetic clutch 40312 is in close contact with the friction plate on the driving sprocket 40313, so that the electromagnetic clutch 40312 is fixedly connected to the driving sprocket 40313. When the electromagnetic clutch 40312 is powered off, the friction plates are separated; there are two sets of driving assemblies 403, and the two sets of driving assemblies 403 are distributed vertically.

[0083] Driving multiple driving units 4031 by one driving motor 4032 reduces the number of motors used, and lowers the equipment cost and energy consumption. The setting of the electromagnetic clutch 40312 can independently control each driving unit 4031, realizing the independent driving of the flexible chain plates 102 on different buffer support frames 101, and improving the flexibility and energy efficiency of the equipment. The design of the double-layer driving assembly increases the conveying capacity and the flexibility of speed adjustment.

[0084] During use, the driving motor 4032 rotates, driving multiple transmission shafts 40311 to rotate synchronously through the chain couplings. When it is necessary to drive the flexible chain plate 102 on a certain buffer support frame 101, the corresponding electromagnetic clutch 40312 is powered on, so that the friction plate on it is in close contact with the friction plate on the driving sprocket 40313, transmitting the power to the driving sprocket 40313, and the driving sprocket 40313 drives the flexible chain plate 102 to rotate. When driving is not required, the electromagnetic clutch 40312 is powered off, the friction plates are separated, and the driving unit 4031 stops driving the corresponding flexible chain plate 102. The two sets of vertically distributed driving assemblies can achieve different conveying speeds and methods, meeting diverse production requirements.

[0085] Such as Figure 18As shown in the figure, the drive units 4031 in the two groups of drive assemblies 403 are divided into 12 groups. When differential conveying is required, only one of the electromagnetic clutches 40312 corresponding to each group can be energized, thereby enabling differential conveying. Taking group a1 and group a2 as examples, the details are as follows:

[0086] In group a1, the upper electromagnetic clutch 40312 is de-energized, which cuts off the power transmission of the upper drive unit 4031, and the upper drive motor 4032 cannot drive the corresponding flexible chain plate 102; while the lower electromagnetic clutch 40312 is energized, and the lower drive motor 4032 transmits power to the drive sprocket 40313 through the closely contacting friction plate, thereby driving the corresponding flexible chain plate 102 to convey materials.

[0087] In group a2, the control logic is opposite to that of group a1. The upper electromagnetic clutch 40312 is energized, and the upper drive motor 4032 can transmit power to the corresponding flexible chain plate 102; the lower electromagnetic clutch 40312 is de-energized, and the power transmission between the lower drive motor 4032 and the corresponding flexible chain plate 102 is interrupted.

[0088] Due to the possible differences in the rotational speeds of the upper and lower drive motors 4032, or under different control strategies, through this precise control of the energization and de-energization of the electromagnetic clutch 40312, the rotational speed of the flexible chain plate 102 corresponding to group a1 is different from that of the flexible chain plate 102 corresponding to group a2.

[0089] And so on. By different energization and de-energization combinations of the electromagnetic clutches 40312 in these 12 groups of drive units 4031, various different differential conveying modes can be realized, meeting diverse production requirements. For example, in material sorting, assembly and other processes, according to different process requirements, the conveying speeds of each section of the flexible chain plate 102 can be flexibly adjusted to improve production efficiency and product quality.

[0090] In this embodiment, the drive sprocket 40313 includes an inner sleeve 403131 and a semi-circular sprocket 403133. The two semi-circular sprockets 403133 are detachably clamped on the inner sleeve 403131 through a locking bolt 403132.

[0091] The detachable design of the drive sprocket 40313 facilitates the installation, disassembly and replacement of the sprocket, reducing the difficulty and cost of equipment maintenance. When the sprocket is worn or fails, it can be quickly replaced, reducing the equipment downtime.

[0092] When installing the drive sprocket 40313, the inner sleeve 403131 is sleeved on the drive shaft 40311, and then the two semi-circular sprockets 403133 are clamped on the inner sleeve 403131 through the locking bolts 403132 to realize the connection between the sprocket and the drive shaft 40311. When the sprocket needs to be replaced, loosen the locking bolt 403132, and the semi-circular sprocket 403133 can be removed.

[0093] In this embodiment, the mounting bracket 402 includes a first mounting plate 4021 and a second mounting plate 4022. The driving unit 4031 is rotatably mounted between the first mounting plate 4021 and the second mounting plate 4022. Both the first mounting plate 4021 and the second mounting plate 4022 are fixedly mounted on the base 401. Upper mounting through grooves 4023 are formed at the upper ends of both the first mounting plate 4021 and the second mounting plate 4022, and lower mounting through grooves 4024 are formed at the lower ends of both the first mounting plate 4021 and the second mounting plate 4022. The upper mounting through grooves 4023 are arranged with their openings upward, and the lower mounting through grooves 4024 are arranged with their openings outward. Upper limit plates 4025 are detachably mounted on the upper ends of both the second mounting plate 4022 and the first mounting plate 4021 through bolts, and side limit plates 4026 are detachably mounted on the side surfaces at the lower ends of both the first mounting plate 4021 and the second mounting plate 4022 through bolts.

[0094] The structural design of the mounting bracket 402 facilitates the installation and disassembly of the driving unit 4031. The upper mounting through grooves 4023 and the lower mounting through grooves 4024 provide convenience for the installation of the driving unit 4031. The settings of the upper limit plates 4025 and the side limit plates 4026 can limit the position of the driving unit 4031 and ensure its stable operation.

[0095] During use, first fix the first mounting plate 4021 and the second mounting plate 4022 on the base 401, and then install the driving unit 4031 between the two mounting plates through the upper mounting through grooves 4023 and the lower mounting through grooves 4024. After installation, install the upper limit plates 4025 and the side limit plates 4026 with bolts to limit the up and down and left and right movements of the driving unit 4031 and ensure its stability during operation. The specific operation is that the drive shaft 40311 in the upper driving unit 4031 is rotatably mounted in the upper mounting through groove 4023, and the drive shaft 40311 in the lower driving unit 4031 is rotatably mounted in the lower mounting through groove 4024.

[0096] In this embodiment, a first guide wheel 1001 and a second guide wheel 1002 are arranged at the bottom of one end of the buffer module 1 close to the driving mechanism 4. The flexible chain plate 102 is arranged through the first guide wheel 1001 and the second guide wheel 1002. The bottom of the flexible chain plate 102 is in rolling contact with both the fixed bracket 1011 and the second guide wheel 1002. The part of the flexible chain plate 102 between the first guide wheel 1001 and the second guide wheel 1002 is arranged in a U-shaped overhang.

[0097] The arrangement of the first guide wheel 1001 and the second guide wheel 1002 and the U-shaped overhang structure of the flexible chain plate 102 play a role in buffering and adjusting the tension of the chain plate, reducing the wear and jitter of the chain plate during operation.

[0098] In this embodiment, an anti-skip tooth assembly 4001 is arranged on the base 401. The anti-skip tooth assembly 4001 includes a first inclined plate 40011 and a second inclined plate 40012. Both the first inclined plate 40011 and the second inclined plate 40012 are fixedly installed on the top of the base 401. After the first inclined plate 40011 and the second inclined plate 40012 are combined, they are arranged in a parabola shape with an upward opening. The first inclined plate 40011 and the second inclined plate 40012 are respectively arranged on both sides of the driving unit 4031.

[0099] The anti-skip tooth assembly 4001 can effectively prevent the phenomenon of skip teeth between the flexible chain plate 102 and the driving sprocket 40313, ensure the stability and reliability of power transmission, reduce the occurrence of equipment failures, and improve the working efficiency and service life of the conveyor.

[0100] When there may be a tendency of skip teeth between the flexible chain plate 102 and the driving sprocket 40313 during operation, the anti-skip tooth assembly 4001 with a parabola shape with an upward opening will play a role in limiting and guiding the flexible chain plate 102. They limit the displacement of the flexible chain plate 102, so that the chain plate always maintains a good meshing state with the driving sprocket 40313, avoiding the occurrence of skip teeth.

[0101] In this embodiment, the anti - dropping mechanism 5 includes a pressure rod 501 and a bearing plate 503. The pressure rod 501 is fixedly installed at the feeding port of the moving confluence conveyor belt 303. The pressure rod 501 is arranged in an inverted L - shape. A first bearing 502 is rotatably installed at the upper end of the pressure rod 501. The bearing plate 503 is fixedly installed at the top of the mounting frame 402. An L - shaped baffle rod 504 is hinged to the bearing plate 503 through a hinge seat 505. The lower end of the L - shaped baffle rod 504 hangs at the discharging port of the buffer module 1. Above the bearing plate 503, there is a moving block 506. Both ends of the bottom of the moving block 506 are fixedly connected with movable rods 507. The lower ends of the movable rods 507 slidably penetrate through the bearing plate 503. A spring 508 is sleeved on the movable rod 507. The top of the spring 508 abuts against the bottom of the moving block 506, and the bottom of the spring 508 presses on the top of the bearing plate 503. The upper end of the movable rod 507 is rotatably connected with a second bearing 5041. The second bearing 5041 is arranged directly below the moving block 506. The top of the moving block 506 is fixedly connected with a pressure - receiving block 509. The pressure - receiving block 509 is arranged in an isosceles trapezoid shape. When the pressure rod 501 moves to the discharging port where discharging is required, the first bearing 502 on the pressure rod 501 can apply a downward pressure on the pressure - receiving block 509, thereby causing the moving block 506 to move downward. The downward - moving moving block 506 applies a downward pressure on the second bearing 5041, causing the lower end of the L - shaped baffle rod 504 to rotate upward, opening the discharging port for discharging materials.

[0102] The anti - dropping mechanism 5 can accurately control the opening and closing of the discharging port of the buffer module 1, effectively prevent materials from falling when discharging is not required, ensuring the safe buffering of materials; when discharging is required, it can timely open the discharging port to ensure the smooth transportation of materials to the confluence module 3, improving the stability and controllability of material transportation.

[0103] During use, under normal circumstances, the spring 508 is in a natural state, keeping the moving block 506 at a certain height. The lower end of the L - shaped baffle rod 504 hangs at the discharging port of the buffer module 1 to block the falling of materials. When the moving confluence conveyor belt 303 moves to the discharging port where discharging is required, the pressure rod 501 moves along, and the first bearing 502 on it contacts the pressure - receiving block 509 and applies a downward pressure. After the pressure - receiving block 509 is subjected to the pressure, it pushes the moving block 506 downward, compressing the spring 508. The moving block 506 applies a pressure on the movable rod 507 through the second bearing 5041, causing the L - shaped baffle rod 504 to rotate upward around the hinge seat 505, opening the discharging port, and the materials can be transported from the buffer module 1 to the moving confluence conveyor belt 303. When the moving confluence conveyor belt 303 leaves this discharging port, the spring 508 recovers its elastic deformation, pushing the moving block 506 upward, and the lower end of the L - shaped baffle rod 504 returns to the discharging port again to block the materials.

[0104] In this embodiment, the meshing equation of the driving sprocket and the flexible chain plate can be introduced:

[0105] The meshing relationship between the driving sprocket 40313 and the flexible chain plate 102 can be described by a geometric equation. Assuming the radius of the sprocket is R and the pitch of the chain plate is p, the meshing condition between the sprocket and the chain plate is:

[0106] 2πR = np, where n is the number of teeth on the sprocket.

[0107] Example: When designing the driving sprocket 40313, the radius of the sprocket can be calculated based on the pitch p of the flexible chain plate 102 and the required number of teeth n. For example, when the driving sprocket needs to be replaced, the appropriate sprocket size can be selected according to the above equation to ensure good meshing between the sprocket and the chain plate.

[0108] Technical effect: By accurately calculating the meshing relationship between the driving sprocket and the flexible chain plate, the stability and reliability of power transmission can be ensured, the occurrence of tooth skipping can be reduced, and the working efficiency of the conveyor can be improved.

[0109] In this embodiment, the control equation of the electromagnetic clutch can also be introduced. The working state of the electromagnetic clutch 40312 can be represented by a switching function S(t), where t is time. When the electromagnetic clutch is energized, S(t) = 1; when the electromagnetic clutch is de-energized, S(t) = 0. Assuming the rotational speed of the driving motor 4032 is W, the rotational speed Ws of the driving sprocket 40313 can be expressed as: Ws = S(t)W.

[0110] Example: During actual operation, the rotational speed of the driving sprocket 40313 can be adjusted by controlling the on-off time of the electromagnetic clutch 40312 according to production requirements and material conveying conditions. For example, during differential conveying, different on-off combinations can be performed on different groups of electromagnetic clutches to achieve multiple different conveying speeds.

[0111] Technical effect: By accurately controlling the working state of the electromagnetic clutch, independent driving of the flexible chain plates 102 on different buffer support frames 101 can be achieved, improving the flexibility and energy efficiency of the equipment and meeting diverse production requirements.

[0112] Working principle:

[0113] The material first enters the diversion module 2. The first motor 2021 drives the fixed diversion conveyor belt 202 to rotate, and the material is conveyed on the fixed diversion conveyor belt 202. If the material needs to be distributed to other buffer support frames 101 except the outermost buffer support frame 101, the first linear module 204 drives the movable diversion conveyor belt 203 to move. At the same time, the third motor 2062 drives the lane-changing component 206 to change the material flow direction, so that the material enters the movable diversion conveyor belt 203 and is conveyed to the target buffer support frame 101.

[0114] In the buffer module 1, the drive motor 4032 rotates, driving multiple transmission shafts 40311 to rotate synchronously through a chain coupling. According to the need, the corresponding electromagnetic clutch 40312 is energized to connect the drive sprocket 40313 with the transmission shaft 40311, driving the flexible chain plate 102 to rotate, and realizing the conveying of materials on the buffer support frame 101. The first guide wheel 1001, the second guide wheel 1002, and the U-shaped hanging structure of the flexible chain plate 102 play a role in buffering and tension adjustment, and the anti-jumping tooth assembly 4001 prevents the chain plate from jumping teeth.

[0115] When it is necessary to take out the materials from the buffer module 1 and send them to the production line, the confluence module 3 starts to work. The second linear module 304 drives the moving confluence conveyor belt 303 to move, so that its feed inlet is communicated with the discharge outlet of the target buffer support frame 101. At the same time, the pressure rod 501 moves with the moving confluence conveyor belt 303. When it reaches the discharge outlet where discharging is required, the first bearing 502 on the pressure rod 501 applies pressure to the pressure-receiving block 509, causing the L-shaped baffle rod 504 to open the discharge outlet, and the materials are conveyed to the feeding port of the production line after being confluent through the moving confluence conveyor belt 303 and the fixed confluence conveyor belt 302. When discharging is not required, the L-shaped baffle rod 504 of the anti-detachment mechanism 5 blocks the materials to prevent them from falling from the discharge outlet.

[0116] Parts not involved in the present invention are the same as or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
