Technical Field

[0001] This application is applied to the field of automated conveying, and specifically relates to a roller conveyor. Background Technology

[0002] Roller conveyors are commonly used to transport pallets and other loads in a specified direction. In existing technology, the rollers of roller conveyors are mostly arranged inwards relative to each other. This requires that some components, such as the transmission mechanism, be arranged outwards, making the entire roller conveyor need to be wider and occupy a larger area. For example, if the load is a pallet with a width of 500mm, the design width of the conveyor needs to be 750mm to meet the conveying requirements. Summary of the Invention

[0003] In view of the above reasons, this application discloses a roller conveyor, including a roller module, a drive module and a line profile. The line profile is arranged opposite to each other on both sides and connected by a base plate. The roller modules are arranged sequentially on the line profile on both sides. The roller module includes rollers for carrying and conveying loads. The drive module drives the rollers of the roller module to run. The rollers of the roller conveyor modules on both sides are positioned relatively far apart and outward.

[0004] Preferably, the roller module includes a bearing housing, a roller, and a drive sprocket for a drive shaft. A bearing is fitted inside the bearing housing, and the drive shaft passes through the bearing and the bearing housing. The roller and the drive sprocket are respectively located at both ends of the drive shaft.

The motor is mounted on the base plate, the transition sprocket passes through the drive bearing housing, and the drive bearing housings are respectively positioned at relative positions on both sides of the linear profile. The drive shaft passes through the transition sprockets at the relative positions on both sides. The transition sprocket is connected to the adjacent transmission sprocket via the transmission chain. The drive shaft is fitted with the drive sprocket, and the motor drives the drive sprocket through the drive chain, thereby driving the transmission sprockets on both sides.

[0006] Preferably, the system also includes the protective module, which includes a drive protective cover and a conveying protective cover. The drive protective cover covers the motor, drive sprocket, and drive chain, and the conveying protective cover covers the bearing housing, the transmission sprocket, and the transmission chain.

[0007] Preferably, the linear profile includes a bearing seat connection portion and a partition connection portion with an upward opening, a first protective cover connection portion extending inward, and a bracket connection portion with an opening on the outer side.

A partition is provided between adjacent bearing housings, and the partition is inserted between the slots on both sides. The lower end of the partition is placed at the partition connection part.

[0013] The advantage of this application is that by setting the two rollers outwards to place the line profile and transmission mechanism between the two rollers, the width space is effectively saved, making it more flexible and suitable for narrow working conditions.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the line profile 1 is an aluminum profile. Two line profiles 1 are arranged opposite each other on the left and right. The line profiles 1 on both sides can be connected by the base plate 2 placed below. Roller modules 3 are respectively arranged above the line profiles 1 on both sides. The roller modules 3 are arranged sequentially along the length direction of the line profiles 1. The roller modules 3 have rollers 4, which are used to carry the load. The rollers 4 of the roller modules 3 on both sides of the line profiles 1 are positioned relatively far apart, that is, the position of the rollers 4 is outward relative to the position of the conveying center line. The rollers 4 on both sides form a conveying surface for the load. The drive module drives the rollers 4 of the roller modules 3 to run, thereby driving and conveying the load. In this embodiment, the rollers 4 of the two roller modules 3 are arranged outwards relative to each other. The drive module, the line profile 1 and other transmission mechanisms are all located between the two rollers 4, thereby effectively saving the width space of this embodiment. It can be flexibly applied to relatively narrow working environments. The roller modules 3 can be set on the line profile according to actual needs. The number and adjacent spacing can be set according to actual working conditions, which is convenient for installation and replacement.

[0029] In some implementations, such as Figure 2 , Figure 5 and Figure 6 As shown, the roller module 3 includes a bearing housing 5, rollers 4, a drive shaft 6, and a drive sprocket 7. The bearing housing 5 houses a bearing 8, which is a deep groove ball bearing 6203-2RS. The drive shaft 6 passes through the bearing 8 in the bearing housing 5, with both ends located outside the bearing housing 5. The rollers 4 and drive sprockets 8 are respectively located at both ends of the drive shaft 6. The rollers 4 are positioned outward relative to the bearing housing 5, while the drive sprockets 7 are positioned inward relative to the bearing housing 5. That is, the rollers 4 on both sides are relatively far apart, while the drive sprockets 7 on both sides are relatively close. The drive sprockets 7 are double-row toothed sprockets. Adjacent roller modules 3 drive adjacent drive sprockets 7 via a drive chain 9. The drive module drives the drive sprockets 7, thereby driving the rollers 4 on both sides to transport the load. It should be noted that the drive shaft 6 and rollers 4 can be integrally injection molded.

[0030] In some implementations, such as Figure 3 and Figure 4 As shown, the drive module includes a motor 10, a drive shaft 11, a drive sprocket 12, a drive chain 13, a transition sprocket 21, and a drive bearing housing 22. The motor 10 is mounted on the base plate 2. The transition sprocket 21 passes through the drive bearing housing 22, with its sprocket portion located outside the drive bearing housing 22. The drive bearing housings 22 are respectively positioned at relative positions on the line profile 1, and the transition sprockets 21 passing through the drive bearing housings 22 on both sides are relatively close to each other. The transition sprockets 21 are connected to the adjacent drive sprockets 7 on both sides through a drive chain 9, so that the transition sprockets 21... The drive shaft 11 operates synchronously with the transmission sprocket 7. The two ends of the drive shaft 11 are respectively passed through the transition sprockets 21 at opposite positions on both sides. The drive sprocket 12 is sleeved in the middle section of the drive shaft 11. The drive sprocket 12 and the transition sprocket 21 rotate synchronously through the drive shaft 11. The motor wheel of the motor 10 is located in the same vertical plane as the drive sprocket 12. The drive chain 13 connects the motor wheel and the drive sprocket 12. The motor 10 drives the drive sprocket 12, thereby driving the transition sprockets 21 and the transmission sprocket 7 on both sides, and then driving the rollers 4 on both sides to run.

[0031] In some implementations, such as Figures 1 to 3 As shown, the drive protective cover 14 is a metal cover that covers the motor 10, drive sprocket 12, and drive chain 13, protecting the drive module and preventing metal debris from falling to the outside during transmission due to metal-to-metal friction between the transmission chain and sprocket, thus preventing contamination of the load or working environment and protecting operators from harm. The conveyor protective cover 15 is also a metal cover that covers the bearing housing 5, transmission sprocket 7, and transmission chain 9, preventing metal debris generated by friction between the transmission chain and sprocket from entering and contaminating the load, thus improving operator safety.

[0032] In some implementations, such as Figures 5 to 8 As shown, the line profile 1 has an upward-opening bearing seat connection part 101. The lower end of the bearing seat 5 has a T-nut 501. The T-nut 501 is locked by a screw that passes vertically through the bearing seat 5. The bearing seat 5 is connected to the bearing seat connection part 101 through the T-nut 501. By rotating the screw, the T-nut 501 is rotated horizontally by 90 degrees and then engages with the bearing seat connection part 101, thus completing the connection between the bearing seat 5 and the line profile 1. Disassembly is similar. This mechanism facilitates the disassembly and installation of the roller module 3.

[0033] In some implementations, such as Figures 1 to 3 , Figure 7 and Figure 8As shown, the line profile 1 has a first protective cover connecting part 102 extending horizontally away from the roller 4. The upper end of the bearing seat 5 has a second protective cover connecting part 502 near the roller 4. One end of the conveying protective cover 15 is connected to the first protective cover connecting part 102, and the other end of the conveying protective cover 15 is connected to the second protective cover connecting part 502. The conveying protective cover 15 and the line profile 1 form a protective space, which covers the bearing seat 5, the transmission sprocket 7 and the transmission chain 9 inside the conveying protective cover 15. End sealing plates 16 are added to both ends of the conveying protective cover 15 to seal the transmission space and prevent metal dust from entering the external space.

[0034] In some implementations, such as Figure 1 , Figure 3 and Figure 4 As shown, the drive protective cover 14 includes a first drive protective cover 1401 and a second drive protective cover 1402. The first drive protective cover 1401 covers one end of the motor wheel of the motor 10 to protect the motor wheel, and the second drive protective cover 1402 covers the drive chain 13 and the drive sprocket 12. The first drive protective cover 1401 can also provide auxiliary support and mounting for one end of the motor.

[0035] In some implementations, such as Figure 2 , Figure 7 and Figure 8 As shown, the profile 1 has a support connection part 103 with a side opening on the side near the roller 4. The friction strip support 17 is connected to the profile 1 near the roller 4 through the support connection part 103. The friction strip support 17 is an L-shaped aluminum profile cut piece, which is convenient for batch preparation. It is used to support the friction strip 18. The friction strip 18 is fixedly connected to the upper end of the friction strip support 17. The length direction of the friction strip 18 is the conveying direction, and the height of the friction strip 18 is higher than the height of the roller 4. The friction strip 18 is used to limit the side edge of the load to prevent it from deviating from the specified conveying surface. The position of the friction strip 18 can be changed by adjusting the position of the friction strip support 17 relative to the profile 1, which can be adjusted according to the actual working conditions.

[0036] In some implementations, such as Figure 2 and Figure 9 As shown, guide blocks 19 are disposed at both ends of friction strip 18. The end of guide block 19 away from friction strip 18 has a guide portion 1901 with an inclined surface for guiding the load and preventing the edge of the load from directly contacting friction strip 18 and causing "jamming". The end of guide block 19 near friction strip 18 has a protruding insertion portion 1902. The shape of insertion portion 1902 matches the cross-sectional shape of friction strip 18. Guide block 19 can be inserted and connected to both ends of friction strip 18 through insertion portion 1902. After insertion and positioning, it can be fixed by bolts or other means to reduce assembly difficulty.

[0037] In some implementations, such as Figure 2 , Figure 5 and Figure 8 As shown, the line profile 1 has a vertically upward-opening partition connecting part 104. The partition connecting part 104 is closer to the direction of the roller 4 than the bearing seat connecting part 101. The bearing seats 5 are spaced apart along the upper end of the line profile 1. The bearing seats 5 have vertical slots 503 on both sides along the length direction of the line profile 1. The two sides of the partition 20 can be inserted into the slots 503 of the adjacent bearing seats 5. The lower end of the partition 20 is placed in the partition connecting part 104 to seal the gap between adjacent bearing seats 5 and prevent metal debris generated during transmission from entering the external space. The width of the partition 20 can be selected according to the spacing width between the bearing seats 5 in the actual working conditions.

[0038] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the scope of the technology disclosed in this application, or make equivalent substitutions for some of the technical features.
