Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more particularly to a buffer roller conveyor. Background Technology

[0002] In the field of automated workpiece conveying, roller conveyors are the core component for achieving continuous workpiece transport. Most existing roller conveyors are fixed structures, and workpieces placed on them are prone to direct impact. Traditional roller conveyors lack targeted buffering and stable reset designs, which can easily damage the roller conveyor, base, or workpiece itself, affecting the continuity of the conveying process and the overall service life of the equipment. Summary of the Invention

[0003] In order to solve the technical problems existing in the background art, the present invention proposes a buffer roller conveyor.

[0004] This invention proposes a buffer roller conveyor, comprising: a base, a first roller conveyor, a second roller conveyor, a buffer assembly, a drive assembly, a limiting assembly, and a transmission assembly. Both the first and second roller conveyors can be used to convey workpieces. The first roller conveyor is movably mounted on the base, and the second roller conveyor is fixedly mounted on the base. The first and second roller conveyors are located on a first vertical plane. A workpiece placed on the first roller conveyor can press the first roller conveyor from a first state parallel to the second roller conveyor to a second state lower than the second roller conveyor. The drive assembly is mounted on the base and connected to the first roller conveyor. The transmission assembly is mounted on the first roller conveyor and can drive the workpiece to move along the length direction of the first roller conveyor. The drive assembly can drive the first roller conveyor to reset from the second state to the first state parallel to the second roller conveyor in the vertical direction so that the transmission assembly can drive the workpiece to move from the first roller conveyor to the second roller conveyor. The buffer assembly is connected to the first roller conveyor to reduce the impact of the workpiece on the base. The limiting assembly can lock the first roller conveyor after the drive assembly drives the first roller conveyor to reset to the first state so that the transmission assembly can drive the workpiece to move from the first roller conveyor to the second roller conveyor.

[0005] Preferably, the buffer assembly includes multiple shock absorbers fixedly mounted on the base, the upper ends of which are all connected to the bottom surface of the first roller conveyor, and the multiple shock absorbers can work together to maintain the first roller conveyor without a workpiece in a first state when in a free state.

[0006] Preferably, the drive assembly includes two hydraulic cylinders that are fixedly installed at both ends of the base. Each of the two hydraulic cylinders has a push rod installed at its output end. Both push rods are fixedly installed on the first roller conveyor and are located on the first horizontal plane. In the depressurized state, the two hydraulic cylinders can jointly maintain the first roller conveyor carrying the workpiece in the second state. In the pressurized state, the two hydraulic cylinders can jointly drive the first roller conveyor carrying the workpiece to reset from the second state to the first state and maintain the first roller conveyor stable in the first state.

[0007] Preferably, the limiting component includes multiple cylinders fixedly installed on the base, the length direction of each cylinder being perpendicular to the length direction of the first roller conveyor, and rods fixedly installed at the output ends of each cylinder. Multiple nylon pads are also fixedly installed at the bottom of the base, and limiting blocks are fixedly installed at the bottom of the nylon pads. Multiple graphite copper plates are also fixedly installed on the base, and the multiple limiting blocks are movably installed on the multiple graphite copper plates one-to-one. The multiple rods are connected to the multiple limiting blocks one-to-one.

[0008] Preferably, the bottom of the limiting block has a T-groove extending along the length of the cylinder, and the graphite copper plate has a T-shaped block that matches the shape of the T-groove.

[0009] Preferably, the transmission assembly includes a motor fixedly mounted on the first roller conveyor, and multiple drive rods are movably mounted on the first roller conveyor. A drive wheel is fixedly mounted on the output end of the motor, and a transmission wheel is fixedly mounted on the end of each drive rod. The drive wheel and the transmission wheel are connected by multiple transmission belts. A roller capable of driving the workpiece to move is fixedly mounted on each drive rod, and the multiple rollers are located on the second horizontal plane.

[0010] The buffer roller conveyor proposed in this invention has the following advantages: It absorbs the impact of workpiece placement through a buffer assembly, preventing direct impact on the base and roller conveyor, reducing component damage, and extending equipment lifespan. The drive assembly and limit assembly work together to achieve precise roller conveyor reset and locking, ensuring stable roller conveyor status during workpiece transfer and guaranteeing smooth transfer of the workpiece to the next roller conveyor, thus improving conveying reliability.

Detailed Implementation

[0012] refer to Figure 1-5This invention proposes a buffer roller conveyor, comprising a base 1, a first roller conveyor 2, a second roller conveyor 3, a buffer assembly 4, a drive assembly 5, a limiting assembly 6, and a transmission assembly 7. Both the first roller conveyor 2 and the second roller conveyor 3 are used to convey workpieces, and they are arranged sequentially along the workpiece conveying direction and coexist on a first vertical plane. The first roller conveyor 2 is movably mounted on the base 1, and the second roller conveyor 3 is fixedly mounted on the base 1. A workpiece placed on the first roller conveyor 2 can, through its own force, press the first roller conveyor 2 from a first state parallel to the second roller conveyor 3 to a second state lower than the second roller conveyor 3. The drive assembly 5 is mounted on the base 1 and connected to the first roller conveyor 2 to provide power for the first roller conveyor 2 to reset; the transmission assembly 7 is mounted on the first roller conveyor 2 and can drive the workpiece to move along the length of the first roller conveyor 2; the buffer assembly 4 is connected to the first roller conveyor 2 to absorb the impact force generated when the workpiece is placed and reduce the impact on the base 1; the limiting assembly 6 can lock the position of the first roller conveyor 2 after it is reset to the first state to ensure the stability of the first roller conveyor 2 during the workpiece conveying process, so that the transmission assembly 7 can smoothly drive the workpiece to move from the first roller conveyor 2 to the second roller conveyor 3.

[0013] The buffer assembly 4 includes multiple shock absorbers 41 fixedly mounted on the base 1, with the upper ends of each shock absorber 41 connected to the bottom surface of the first roller conveyor 2. The shock absorbers 41 are in a pre-compressed free state. When there is no workpiece load, the multiple shock absorbers 41 collectively support the first roller conveyor 2, maintaining it in the first state. When a workpiece is placed on the first roller conveyor 2, the force of the workpiece causes the first roller conveyor 2 to move downwards. The shock absorbers 41 are further compressed and absorb the impact force through their own elastic deformation, preventing the workpiece from directly impacting the base 1.

[0014] The drive assembly 5 includes two hydraulic cylinders 51 fixedly mounted at both ends of the base 1. Each hydraulic cylinder 51 has a push rod 52 mounted on its output end. Both push rods 52 are fixedly mounted on the first roller conveyor 2 and are both on the first horizontal plane. The two hydraulic cylinders 51 synchronously perform depressurization or pressurization actions to ensure that the first roller conveyor 2 is subjected to balanced force and moves smoothly in the vertical direction. When the hydraulic cylinders 51 are in the depressurization state, they cannot provide lifting force, and the first roller conveyor 2, loaded with the workpiece, remains in the second state under the combined action of the workpiece force and the compressive force of the shock absorber 41. When the hydraulic cylinders 51 are in the pressurization state, their output ends drive the push rods 52 to lift the first roller conveyor 2 upwards, gradually restoring it from the second state to the first state parallel to the second roller conveyor 3, and continuously maintaining pressure to ensure the first roller conveyor 2 remains stable in this state.

[0015] The limiting assembly 6 includes multiple cylinders 61 fixedly mounted on the base 1, with the length direction of each cylinder 61 perpendicular to the length direction of the first roller conveyor 2. A rod 62 is fixedly mounted on the output end of each cylinder 61. Multiple nylon gaskets 63 are also fixedly mounted on the bottom of the base 1, with limiting blocks 64 fixedly mounted on the bottom of each nylon gasket 63. Multiple graphite copper plates 65 are also fixedly mounted on the base 1, with each limiting block 64 movably mounted on one of the graphite copper plates 65. Each rod 62 is connected to each limiting block 64 in a corresponding manner. The bottom of each limiting block 64 has a T-slot 66 extending along the length direction of the cylinder 61, and each graphite copper plate 65 has a T-shaped block 67 that matches the shape of the T-slot 66. Multiple cylinders 61 operate synchronously, driving rod 62 to drive limit block 64 to slide along T-block 67 in a directional manner, preventing limit block 64 from shifting, and ensuring that T-slot 66 and T-block 67 are engaged, so that the first roller 2 can be fixed after the first roller 2 carrying the workpiece rises, and the workpiece can be transferred subsequently.

[0016] The transmission assembly 7 includes a motor 71 fixedly mounted on the first roller conveyor 2. Multiple drive rods 72 are also movably mounted on the first roller conveyor 2, and these drive rods 72 are evenly arranged along the length of the first roller conveyor 2. A drive wheel 73 is fixedly mounted at the output end of the motor 71, and a transmission wheel 74 is fixedly mounted at the end of each drive rod 72. The drive wheel 73 and the transmission wheel 74 are connected by multiple transmission belts 75. A roller 76 is fixedly mounted on each drive rod 72, and the multiple rollers 76 are located on a second horizontal plane and protrude from the workpiece support surface of the first roller conveyor 2. After the motor 71 starts, power is transmitted to each transmission wheel 74 via the drive wheel 73 and transmission belts 75, causing the drive rods 72 and rollers 76 to rotate synchronously. The rollers 76 contact the bottom surface of the workpiece, generating friction, which in turn drives the workpiece to move along the length of the first roller conveyor 2.

[0017] When there is no workpiece load, the shock absorber 41 of the buffer assembly 4 is in a pre-compressed free state, the first roller conveyor 2 is maintained in a first state that is flush with the second roller conveyor 3, the hydraulic cylinder 51 of the drive assembly 5 is in a depressurized state, and the cylinder 61 of the limit assembly 6 does not move.

[0018] After the workpiece is conveyed to the input end of the first roller conveyor 2, the force of the workpiece causes the first roller conveyor 2 to move downward against the pre-compression force of the shock absorber 41. The shock absorber 41 compresses and absorbs the impact force, and the first roller conveyor 2 enters a second state lower than the second roller conveyor 3. At this time, the oil cylinder 51 remains in a depressurized state and does not apply a lifting force.

[0019] After the workpiece is completely placed on the first roller conveyor 2, the hydraulic cylinder 51 starts and pressurizes, and the output end drives the push rod 52 to lift the first roller conveyor 2 upward in sync. The shock absorber 41 gradually returns to the pre-compressed free state as the first roller conveyor 2 rises, until the stroke of the hydraulic cylinder 51 ends, and the first roller conveyor 2 and the second roller conveyor 3 are aligned again. The hydraulic cylinder 51 maintains pressure to ensure the stability of the first roller conveyor 2.

[0020] Subsequently, the cylinder 61 of the limiting component 6 is activated, and the driving rod 62 drives the limiting block 64 to slide along the T-shaped block 67 of the graphite copper plate 65, so that the T-shaped groove 66 of the limiting block 64 is fully engaged with the T-shaped block 67. The bottom of the first roller conveyor 2 is supported and limited by the nylon gasket 63, restricting the vertical displacement of the first roller conveyor 2. At this time, the oil cylinder 51 is closed, and the first roller conveyor 2 remains in the first state under the locking action of the limiting component 6.

[0021] When the motor 71 of the transmission assembly 7 starts, the power is transmitted to each drive rod 72 through the drive wheel 73, the transmission belt 75, and the transmission wheel 74, which drives the roller 76 to rotate synchronously. The friction between the roller 76 and the bottom surface of the workpiece drives the workpiece to move along the first roller track 2 to the second roller track 3 until the workpiece is completely in the second roller track 3, thus completing a single workpiece transfer.

[0022] After the workpiece leaves the first roller conveyor 2, the cylinder 61 of the limiting component 6 is depressurized, the rod 62 drives the limiting block 64 to reset, the T-slot 66 and the T-block 67 disengage, and the device waits for the next workpiece to be conveyed, repeating the above process.
