Description

Technical Field

[0001] The invention relates to the technical field of rail conveying, and belongs to a standardized pallet conveying system based on standard aluminum profiles, in particular to a modular sprocket roller conveying system. Background Art

[0002] In the standardized pallet system, roller conveyors are used in actual production as a heavy-duty form. Roller conveyors are generally chain-driven and bevel gear-driven. Whether chain-driven or bevel gear-driven, when the load of a single pallet is between 300kg and 700kg, an accumulation structure is used to achieve the function of a single drive driving multiple stations. The existing roller conveyors on the market have failed to standardize the roller wheel group into a standard module. Once one or more roller wheel groups fail, it is difficult to repair and replace them, which affects the application of the entire roller conveyor.

[0003] In addition to the above shortcomings, in the existing sprocket transmission structure on the market, the installation dimensions of the sprocket cannot be effectively guaranteed in the design of most conveying equipment. Therefore, the tension of the sprocket needs to be guaranteed by machining holes. Once the sprocket is designed, the spacing cannot be adjusted. In addition, due to the influence of the tolerance of the chain and sprocket, the wheelbase of the sprocket cannot be accurately grasped. The chain is relatively loose after assembly, and it is also difficult to assemble the chain. At the same time, the current design generally requires drilling holes on the side of the support frame and fine processing to meet the assembly requirements of the bearing. This has certain technical difficulties, and the processing cycle is long, the cost is high, and the frame is easy to deform. In addition, the sprocket cannot be placed at the back, the degree of freedom during assembly is low, and the assembly efficiency is low. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, an object of the present invention is to provide a modular sprocket roller conveyor system that is easy to repair and replace, thereby improving the flexibility of assembly.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a modular sprocket roller conveyor system, including a supporting frame, a driving mechanism and a plurality of roller groups; the plurality of roller groups are arranged in sequence on the supporting frame, each roller group includes a roller shaft and fixed module seats arranged at both ends of the roller shaft, the roller shaft is detachably mounted on the supporting frame through the fixed module seats at both ends, the roller shaft is rotatably connected to the fixed module seat, the roller is fixedly connected to the roller shaft, the roller is arranged on the inner side of the supporting frame, one end of the roller shaft is the driving end, and the other end is the driven end, the driving end of the roller shaft is equipped with a sprocket transmission assembly, and the plurality of sprocket transmission assemblies are connected by chain transmission, and the output gear of the driving mechanism is transmitted to the plurality of sprocket transmission assemblies in a two-stage transmission mode or an end transmission mode, thereby driving the plurality of roller groups on the entire conveying system to rotate.

[0006] Based on the above technical solution, the core roller group components are standardized and independent, so that the purpose of driving all roller groups by a single drive is achieved, and the overall structure is simplified. At the same time, when a roller group of the conveying system fails, the roller group can be replaced as a whole without changing other structures of the entire conveying system, which is simple to operate and improves efficiency.

[0007] Furthermore, the sprocket transmission assembly includes a first sprocket and a second sprocket, the first sprocket and the second sprocket are fixedly assembled on the driving end of the roller shaft, two adjacent first sprockets in a number of roller groups are transmission connected, two adjacent second sprockets in a number of roller groups are transmission connected, and the first sprocket and the second sprocket on each roller group are respectively connected to the roller groups on both sides.

[0008] Based on the above technical solution, the first sprockets and the second sprockets of the plurality of roller groups are connected in pairs and alternately, so that a single drive drives the operation of the entire conveying system.

[0009] Furthermore, the driving end of the roller shaft extends to the outside of the fixed module seat to form a protruding section, and the first sprocket and the second sprocket are fixedly assembled on the protruding section of the driving end of the roller shaft.

[0010] Based on the above technical solution, the driving component is arranged outside the supporting frame to facilitate assembly and disassembly.

[0011] Furthermore, the two-stage transmission method is that the output gear of the driving mechanism is connected to two adjacent first sprockets, and the two adjacent first sprockets are located in the middle of the entire conveying system. The two adjacent first sprockets serve as central transmission sources to drive the roller groups on both sides to rotate in turn.

[0012] Based on the above technical solution, the two groups of roller groups connected to the output gear of the driving mechanism are respectively set as roller group A and roller group a, and the several roller groups on the side of roller group A away from roller group a are respectively set as roller group B and roller group C, and so on, and the several roller groups on the side of roller group a away from roller group A are respectively set as roller group b and roller group c, and so on; the output gear of the driving mechanism drives the first sprocket on roller group A and roller group a to rotate, thereby driving the roller shafts of roller group A and roller group a to rotate, and the two rollers connected to the roller shafts The second sprocket of roller group A rotates synchronously with the second sprocket of roller group B, driving the roller shaft of roller group B to rotate, the roller installed on the roller shaft of roller group B rotates synchronously with the first sprocket, the first sprocket of roller group B rotates synchronously with the first sprocket of roller group C, driving the roller shaft of roller group C to rotate, the roller installed on the roller shaft of roller group C rotates synchronously with the second sprocket; the above connection method is connected in sequence, the rotation of roller group A drives the roller group on one side to operate, and the same is true for roller group A and the roller group on the other side. The two-stage transmission method uses two groups of roller groups as power sources, so that the driving force is transmitted to both sides respectively, ensuring the driving strength and driving efficiency, with small transmission error, short transmission distance, and not easy to trip.

[0013] Furthermore, the end transmission method is that the output gear of the driving mechanism is connected to a first sprocket, and the first sprocket is located at the end of the entire conveying system. The first sprocket serves as an end transmission source to drive the roller group on one side to rotate.

[0014] Based on the above technical solution, this transmission method is the same as the connection transmission method of the above-mentioned A roller group, B roller group, and C roller group, and is suitable for short-distance transmission.

[0015] Furthermore, the support frame is composed of two groups of aluminum profiles parallel to each other, the driving mechanism includes a motor and a reducer, the motor and the reducer are fixed on the side walls outside the support frame, the first sprocket and the second sprocket are arranged on the outside of the support frame, and there are two rollers, which are connected to the roller shaft by a key.

[0016] Based on the above technical solution, the standardized aluminum profile can ensure the requirements of parallelism and flatness. The profile has a notch, and the notch of the profile is used as the installation reference of the roller group, which is convenient for installation and adjustment of the fixed module seat without additional drilling. The strength and accuracy of the support frame are ensured while simplifying the processing technology.

[0017] Furthermore, a circular assembly cavity is provided on the fixed module seat, a bearing is installed in the circular assembly cavity, and the roller shaft is rotatably connected to the fixed module seat through the bearing.

[0018] Based on the above technical solution, the module seat and the side bearing bracket are connected to form a fixed module seat with fixed size through positioning features. The circular assembly cavity and the bearing are of standardized size, which matches the size of the roller shaft, is easy to assemble and replace, and ensures assembly accuracy.

[0019] Furthermore, two adjacent first sprockets are connected by chain transmission, two adjacent second sprockets are connected by chain transmission, the distance between two adjacent fixed module seats matches the chain length, the gap between two adjacent fixed module seats is positioned by a wedge block, and several fixed module seats on both sides of the support frame are symmetrically arranged.

[0020] Based on the above technical solution, in the process of assembling the traditional chain, the length of the chain should be adjusted according to the wheelbase of the sprocket, and the chain links should be appropriately increased or decreased. The minimum unit of change is one chain link. In the transmission system with high precision requirements, there may be an error of half a chain link or less, which will cause the chain assembly to be too loose or tight, making the entire transmission system run not smoothly enough. In particular, in this device, a drive drives multiple independent roller groups to rotate through multiple chains. In order to prevent the accumulation of transmission errors from causing the entire system to stop, the transmission accuracy of each transmission unit has high requirements. Therefore, in the process of assembling the present invention, the position of each fixed module seat should be appropriately adjusted in turn according to the length of the chain to ensure that the length of the chain is fully matched with the distance between the two adjacent fixed module seats. After the gap between the two adjacent fixed module seats is measured at the assembly site, a wedge block matching the gap size is polished and directly assembled to the conveying system. The wedge block can completely locate the position of the fixed module seat to ensure that when the connection between the fixed module seat and the support frame is unstable, the position of the fixed module seat does not move, affecting the transmission accuracy. The assembly method of the present invention can ensure that the sprocket spacing is subsequently adjustable and infinitely adjustable.

[0021] Furthermore, the wedge block is provided with a base, and bolt holes are provided on the base and connected with the extension bolt holes of the fixed module seats on both sides by bolts. The extension bolt hole on one side of the fixed module seat is open, which is convenient for adjusting the position of the connection bolt of the wedge block, ensuring that the wedge block is stably connected with the fixed module seats on both sides.

[0022] Furthermore, the first sprocket and the second sprocket of each roller group form a driving sprocket group, a limit sleeve and a gasket are arranged between the fixed module seat and the driving sprocket group, and the driving sprocket group is sequentially provided with a gasket, a disc spring, a gasket and a locking ring toward the end face direction of the roller shaft; an isolation ring is arranged between the first sprocket and the second sprocket.

[0023] Based on the above technical solution, the limit sleeve ensures that the assembly position of the drive sprocket group is consistent, and at the same time avoids interference between the drive sprocket group and the fixed module seat. The limit sleeve, isolation ring, disc spring and locking ring work together to axially position the first sprocket and the second sprocket.

[0024] Furthermore, a horizontal reference plane is set at the bottom of the fixed module seat, and the supporting frame is an aluminum profile with a notch on the upper surface. The fixed module seat is positioned with the horizontal reference plane at the bottom and the upper surface of the aluminum profile. Extensions are provided at the edges of both ends of the fixed module seat, and bolt holes are opened on the extensions, one side of which has an open bolt hole. The fixed module seat is fixed and locked with the notch on the upper surface of the aluminum profile by bolts.

[0025] Based on the above technical solution, the notch of the profile is used as the installation reference of the conveying roller, and the horizontal reference surface at the bottom of the fixed module seat can ensure the installation accuracy of the fixed module seat, thereby ensuring that the axes of all roller groups are on the same plane.

[0026] Furthermore, the conveying system is provided with a top cover, a horizontal reference plane is provided on the top of the fixed module seat, the top cover is installed on the horizontal reference planes on the tops of several fixed module seats by means of slots, several empty slots are provided on both sides of the top cover, the rollers are provided in one-to-one correspondence with the empty slots, the rollers protrude above the top cover through the empty slots, and dust boxes are provided on the outside of the driving ends and driven ends of the several roller groups.

[0027] Based on the above technical solution, the top cover has protrusions on both sides, and the protrusions on both sides of the top cover are located on the same horizontal plane as the two sides of the supporting frame, which is convenient for placing the pallet on the conveying system. The horizontal reference plane on the top of the fixed module seat ensures the installation accuracy of the top cover and avoids the top cover from tilting and the empty groove of the top cover from interfering with the roller. The top cover and the dust box can protect and dustproof the conveying system and prevent the mechanical transmission from being affected by external factors.

[0028] Based on the above technical solution, the working process of the present invention is as follows: the motor drives the output gear of the reducer to rotate, driving the sprocket connected to the output gear of the reducer to rotate, and through the transmission connection between adjacent sprockets, driving all roller groups to rotate to complete the operation of the entire roller track; if one group of roller groups is damaged and needs to be replaced, first remove the top cover and the dust box, then remove the chain connected to the first sprocket and the second sprocket of the roller group to be replaced, and then unscrew the connecting bolts between the two fixed module seats and the support frame of the roller group to be replaced, replace the entire roller group, and then connect the two fixed module seats, the chain, the top cover and the dust box in sequence. If a wedge block is installed between two adjacent fixed module seats, the wedge block must be removed before removing the fixed module seat, and the wedge block must be assembled after installing the fixed module seat.

[0029] The assembly method of the modular sprocket roller conveyor system is as follows: a plurality of roller groups are assembled on the supporting frames parallel to each other on both sides, the roller shaft of each roller group is detachably connected to the two sides of the supporting frame through the fixed module seats at both ends, the driving end of the roller shaft is fixedly equipped with the first sprocket and the second sprocket, the output gear of the reducer is connected to the first sprocket of the two adjacent roller groups through transmission, the two adjacent roller groups are used as the central transmission end and are sequentially connected to the two sides through the chain, the connection mode is that the two adjacent first sprockets are connected through the chain transmission, the two adjacent second sprockets are connected through the chain transmission, and the first sprocket and the second sprocket on each roller group are respectively connected to the roller groups on both sides;

[0030] The motor drives the output gear of the reducer to rotate, which drives the first sprocket connected to the output gear of the reducer to rotate, and drives all rollers to rotate through the transmission connection between the adjacent first sprocket and the second sprocket. The two rollers fixedly mounted on the rollers rotate to complete the transmission of the upper product.

[0031] When a roller group fails during the operation of the entire conveyor line, the failed roller group is repaired and replaced. First, the chain connected to the first sprocket and the second sprocket of the roller group to be replaced is removed, and then the connecting bolts between the two fixed module seats and the support frame of the roller group to be replaced are removed, and the entire roller group is replaced. During the replacement process, the horizontal reference surfaces at the bottom of the fixed module seats at both ends of the new roller group must be positioned in coordination with the upper surface of the support frame. After the fixed module seats at both ends are fixed, the chains connected to the first sprocket and the second sprocket are reinstalled. At this time, the maintenance of the conveying system is completed and the conveying system is restored to normal operation.

[0032] Furthermore, several fixed module seats are assembled on the support frame on the same side, and the spacing between two adjacent fixed module seats is adjusted by wedge blocks, and several fixed module seats on both sides of the support frame are symmetrically arranged; when assembling the roller group, the position of each fixed module seat is adjusted in turn according to the length of the chain to ensure that the length of the chain matches the distance between two adjacent fixed module seats. After the gap between two adjacent fixed module seats is measured at the assembly site, a wedge block matching the size of the gap is polished and directly assembled to the conveying system, and the wedge block is connected and fixed to the fixed module seats on both sides;

[0033] When replacing a set of rollers on the conveying system, first remove the wedge block and then remove the fixed module seat; when installing a new roller set, assemble the wedge block after installing the fixed module seat.

[0034] The beneficial effects of the present invention are as follows: the present invention designs the roller set as a standardized module, adopts a modular assembly method, has good assembly flexibility, can be stocked in batches to improve the production efficiency of the line body and shorten the delivery cycle, and is convenient for the maintenance and replacement of individual components of the entire conveying system.

The first sprocket 7 and the second sprocket 8 on each roller group are respectively connected to the roller groups on both sides. The motor 2 drives the output gear of the reducer to rotate, and the output gear of the reducer drives the several roller groups on the entire conveying system to rotate in a two-stage transmission mode. The two adjacent roller groups are used as the central transmission end and are sequentially connected to other roller groups on both sides through the chain 17.

[0046] Based on the above technical solution, the core roller group components are standardized and independent, so that the purpose of driving all roller groups by a single drive is achieved, and the overall structure is simplified. At the same time, when a roller group of the conveying system fails, the roller group can be replaced as a whole without changing other structures of the entire conveying system, which is simple to operate and improves efficiency.

[0047] Furthermore, the driving end of the roller shaft 4 extends to the outside of the fixed module seat to form a protruding section, and the first sprocket 7 and the second sprocket 8 are fixedly assembled on the protruding section of the driving end of the roller shaft.

[0048] Based on the above technical solution, the driving component is arranged outside the supporting frame to facilitate assembly and disassembly.

[0049] Furthermore, the two-stage transmission method is that the output gear of the reducer is connected to two adjacent first sprockets, and the two adjacent first sprockets are located in the middle of the entire conveying system. The two adjacent first sprockets serve as central transmission sources to drive the roller groups on both sides to rotate in turn.

[0050] Based on the above technical solution, the two roller groups connected to the output gear of the reducer are respectively set as roller group A and roller group a, and the roller groups on the side of roller group A away from roller group a are respectively set as roller group B and roller group C, and so on, and the roller groups on the side of roller group a away from roller group A are respectively set as roller group b and roller group c, and so on; the output gear of the reducer drives the first sprocket on roller group A and roller group a to rotate, thereby driving the roller shafts of roller group A and roller group a to rotate, and the two rollers connected to the roller shafts The second sprocket of roller group A rotates synchronously with the second sprocket of roller group B, driving the roller shaft of roller group B to rotate, the roller installed on the roller shaft of roller group B rotates synchronously with the first sprocket, the first sprocket of roller group B rotates synchronously with the first sprocket of roller group C, driving the roller shaft of roller group C to rotate, the roller installed on the roller shaft of roller group C rotates synchronously with the second sprocket; connect in sequence according to the above connection method, the rotation of roller group A drives the roller group on one side to operate, and the same applies to roller group A and the roller group on the other side. The two-stage transmission method uses two groups of roller groups as power sources, so that the driving force is transmitted to both sides respectively, ensuring the driving strength and driving efficiency, with small transmission error, short transmission distance, and not easy to trip.

[0051] Based on the above, the present invention can also adopt an end transmission method for transmission, which is as follows: the output gear of the reducer is connected to a first sprocket, and the first sprocket is located at the end of the entire conveying system. The first sprocket serves as an end transmission source to drive the roller group on one side to rotate.

[0052] Based on the above technical solution, this transmission method is the same as the connection transmission method of the above-mentioned A roller group, B roller group, and C roller group, and is suitable for short-distance transmission.

[0053] Furthermore, the support frame 1 is composed of two sets of aluminum profiles parallel to each other, the motor 2 and the reducer 3 are fixed on the side walls outside the support frame, the first sprocket 7 and the second sprocket 8 are arranged on the outside of the support frame 1, and the two rollers 6 are connected to the roller shaft 4 by keys.

[0054] Based on the above technical solution, the standardized aluminum profile can ensure the requirements of parallelism and flatness. The profile has a notch, and the notch of the profile is used as the installation reference of the roller group, which is convenient for installing and adjusting the fixed module seat 5 without the need for additional drilling. This ensures the strength and accuracy of the support frame 1 while simplifying the processing technology.

[0055] Furthermore, a circular assembly cavity is provided on the fixed module seat 5 , a bearing is installed in the circular assembly cavity, and the roller shaft 4 is rotatably connected to the fixed module seat through the bearing 9 .

[0056] Based on the above technical solution, the present invention connects the module seat and the side bearing bracket into a fixed module seat with fixed size through positioning features. The circular assembly cavity and the bearing are of standardized sizes, which match the size of the roller shaft, are easy to assemble and replace, and ensure assembly accuracy.

[0057] Furthermore, two adjacent first sprockets are connected by chain transmission, two adjacent second sprockets are connected by chain transmission, the distance between two adjacent fixed module seats is matched with the chain length, the gap between two adjacent fixed module seats 5 is positioned by a wedge block 10, and several fixed module seats on both sides of the support frame are symmetrically arranged.

[0058] Based on the above technical solution, in the process of assembling the traditional chain, the length of the chain should be adjusted according to the wheelbase of the sprocket, and the chain links should be appropriately increased or decreased. The minimum unit of change is one chain link. In the transmission system with high precision requirements, there may be an error of half a chain link or less, which will cause the chain assembly to be too loose or tight, making the entire transmission system run not smoothly enough. In particular, in this device, a drive drives multiple independent roller groups to rotate through multiple chains. In order to prevent the accumulation of transmission errors from causing the entire system to stop, the transmission accuracy of each transmission unit has high requirements. Therefore, in the process of assembling the present invention, the position of each fixed module seat should be appropriately adjusted in turn according to the length of the chain to ensure that the length of the chain is fully matched with the distance between the two adjacent fixed module seats. After the gap between the two adjacent fixed module seats is measured at the assembly site, a wedge block matching the gap size is polished and directly assembled to the conveying system. The wedge block can completely locate the position of the fixed module seat to ensure that when the connection between the fixed module seat and the support frame is unstable, the position of the fixed module seat does not move, affecting the transmission accuracy. The assembly method of the present invention can ensure that the sprocket spacing is subsequently adjustable and infinitely adjustable.

The extension bolt holes 5.3 on one side of the fixed module seat are open, which is convenient for adjusting the position of the connection bolts of the wedge block 10. It is ensured that the wedge block 10 is stably connected with the fixed module seats 5 on both sides.

[0060] Furthermore, the first sprocket 7 and the second sprocket 8 of each roller group form a driving sprocket group, a limit sleeve 11 and a gasket are arranged between the fixed module seat 5 and the driving sprocket group, and the driving sprocket group is sequentially provided with a gasket, a disc spring 13, a gasket and a locking ring 14 toward the end face direction of the roller shaft; an isolation ring 12 is arranged between the first sprocket 7 and the second sprocket 8.

[0061] Based on the above technical solution, the limit sleeve 11 ensures that the assembly position of the drive sprocket group is consistent, and at the same time avoids interference between the drive sprocket group and the fixed module seat 5. The limit sleeve 11, isolation ring 12, disc spring 13 and locking ring 14 work together to axially position the first sprocket 7 and the second sprocket 8.

The horizontal reference plane on the top of the fixed module seat 5 ensures the installation accuracy of the top cover and avoids the top cover 15 from tilting and the empty groove of the top cover from interfering with the roller 6. The top cover 15 and the dustproof box 16 can protect and dustproof the conveying system and prevent the mechanical transmission from being affected by external factors.

[0066] Based on the above technical solution, the working process of the present invention is as follows: the motor 2 drives the output gear of the reducer to rotate, drives the sprocket connected to the output gear of the reducer to rotate, and drives all the roller groups to rotate through the transmission connection between adjacent sprockets to complete the operation of the entire roller track; if one of the roller groups is damaged and needs to be replaced, first remove the top cover 15 and the dust box 16, then remove the chain connected to the first sprocket 7 and the second sprocket 8 of the roller group to be replaced, and then unscrew the connecting bolts between the two fixed module seats 5 and the support frame 1 of the roller group to be replaced, replace the entire roller group, and then connect the two fixed module seats 5, the chain, the top cover 15 and the dust box 16 in sequence. If a wedge block 10 is installed between two adjacent fixed module seats 5, the wedge block 10 must be removed before removing the fixed module seat 5, and the wedge block 10 must be assembled after installing the fixed module seat 5.

[0068] The motor drives the output gear of the reducer to rotate, driving the first sprocket connected to the output gear of the reducer to rotate, and through the transmission connection between the adjacent first sprocket and the second sprocket, drives all rollers 4 to rotate, and the two rollers 6 fixedly assembled on the rollers 4 rotate to complete the transmission of the upper product;

[0069] When a certain roller group fails during the operation of the entire conveyor line, the failed roller group is repaired and replaced. First, the chain connected to the first sprocket 7 and the second sprocket 8 of the roller group to be replaced is removed, and then the connecting bolts between the two fixed module seats 5 and the support frame 1 of the roller group to be replaced are removed, and the entire roller group is replaced.
