Description

Technical Field

[0001] This invention relates to the technical field of loading and unloading conveying equipment, and in particular to a single-power multi-station material distribution and conveying system. Background Technology

[0002] Taking the automated production of sandblasted steel pipes as an example, the sandblasting process is the bottleneck process, with a cycle time many times longer than other processes. To match the cycle time, the sandblasting process is set up with multiple workstations. The preceding process is a single-pipe sequential operation. After completing the operation of one round pipe at a time, the round pipe needs to be allocated to an idle sandblasting workstation, which creates a multi-workstation material distribution requirement for the material distribution system. When subsequent processes require the simultaneous operation of multiple pipes at multiple workstations in the sandblasting process, it creates a requirement for separate loading and unloading at multiple workstations in the sandblasting process. Conventional solutions have an independent loading and unloading system (with independent power) for each workstation or manual transfer, which is costly. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a single-power multi-station material distribution and conveying system. By setting grooves of different positions, sizes, angles, and numbers on the push plate, it is possible to meet the needs of independent control of different stations with a single power source, so as to realize the feeding, waiting, and direct rolling of round tubes at the corresponding stations.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A single-power multi-station material conveying system includes a frame, a push plate on the frame, a motor on the push plate to drive the push plate to move, and a groove on the push plate; the frame also includes a connecting mechanism and a material dispensing mechanism, the connecting mechanism being connected to both the push plate and the material dispensing mechanism; the connecting mechanism includes a connecting rod and two cam bearing followers at a 90° angle, one of which is located in the groove of the push plate and drives the connecting mechanism to move under the push of the groove; the other cam bearing follower is located in the material dispensing mechanism and, when the connecting mechanism moves, pushes the material dispensing mechanism to control the station state to unloading, waiting, or direct rolling.

[0005] By adopting the above technical solution, the motor drives the push plate to move. According to the needs of the workstation for unloading, waiting, or direct rolling, one or more grooves of different sizes and angles are opened at different positions on the push plate. During the movement of the push plate, the cam bearing follower located in the groove of the push plate on the connecting mechanism can drive the connecting mechanism to move under the push of the groove. At the same time, since another cam bearing follower of the connecting mechanism is located in the material distribution mechanism, the material distribution mechanism can be pushed to control the workstation state as unloading, waiting, or direct rolling when the connecting mechanism moves. Thus, by setting grooves of different positions, sizes, angles, and numbers on the push plate, the need for independent control of different workstations can be met by a single power source, so as to realize the unloading, waiting, and direct rolling of the round tube at the corresponding workstation.

[0006] Furthermore, the material distribution mechanism includes a follower plate, a rotating shaft, a fixed feeding plate, and multiple sets of spaced rotating baffles. The follower plate and the rotating baffles are both fixed on the rotating shaft. The rotating shaft is rotatably connected to the fixed feeding plate. The fixed feeding plate has an opening as a feeding station. When the rotating baffle is in its initial position, the tilt angle of the rotating baffle is the same as that of the fixed feeding plate, and the rotating baffle covers the opening on the fixed feeding plate.

[0007] By adopting the above technical solution, the follower plate rotates under the push of the connecting mechanism, which drives the rotating shaft to rotate around the shaft, and the rotating shaft drives the rotating baffle to rotate. When the rotating baffle is in the initial position, the tilt angle of the rotating baffle is consistent with that of the fixed feeding plate, and the rotating baffle covers the opening position on the fixed feeding plate, so that the round tube can roll through the fixed feeding plate and the rotating baffle to the next feeding station of the fixed feeding plate. This allows the round tube to be fed, waited for and rolled directly through the corresponding station by changing the angle of the rotating baffle at different feeding stations.

[0008] Furthermore, the rotating baffle and the fixed feeding plate are offset along the length of the rotating axis.

[0009] By adopting the above technical solution, the rotation process of the rotating baffle does not interfere with the fixed feeding plate.

[0010] Furthermore, the cam bearing follower is located inside the follower plate of the material distribution mechanism.

[0011] By adopting the above technical solution, a cam bearing follower of the connecting mechanism is located inside the follower plate of the material distribution mechanism, so that when the connecting mechanism moves, it pushes the follower plate to rotate around the rotating shaft. The rotating shaft drives the change of the angle of the rotating baffle, ultimately realizing the unloading, waiting and direct rolling of the round tube at the corresponding station.

[0012] Furthermore, the rotating shaft is rotatably connected to the fixed feed plate via bearings.

[0013] By adopting the above technical solution, the friction between the rotating shaft and the fixed feed plate is reduced, which is beneficial to the rotation of the rotating shaft.

[0014] Furthermore, the frame is provided with a base plate, the base plate is provided with a first guide rail, and the push plate is provided on the base plate through the first guide rail; the base plate is provided with a second guide rail, and the connecting mechanism is provided on the base plate through the second guide rail.

[0015] Furthermore, the motor drives the push plate to move along the first guide rail via a gear and rack.

[0016] Furthermore, the frame is also equipped with a feeding mechanism, which includes a buffer plate, a cylinder, a lifting square tube, a lifting plate, a connecting plate, and a linear guide rail. The buffer plate is connected to the frame and is used to store the round tubes completed in the previous process. The cylinder seat of the cylinder is connected to the buffer plate, and the piston rod is connected to the lifting square tube. The linear guide rail is connected to the buffer plate, and the lifting square tube is slidably connected to the linear guide rail through the connecting plate. Multiple lifting plates are connected along the length of the lifting square tube, and the lifting plate is used to lift the round tubes from the buffer plate into the dispensing mechanism.

[0017] By adopting the above technical solution, the buffer plate is used to store the round tubes completed in the previous process. When the piston rod of the cylinder extends, the lifting square tube moves upward along the linear guide under the drive of the piston rod of the cylinder, thereby driving the lifting plate to lift the heat exchange round tube. The lifting plate lifts the round tube from the buffer plate into the material distribution mechanism, thereby realizing the feeding mechanism to transport the round tubes completed in the previous process to the material distribution mechanism.

[0018] Furthermore, the buffer plate is provided in two types, namely buffer plate one and buffer plate two, which are arranged at intervals, and buffer plate one is connected to the cylinder and linear guide rail; the lifting square tube is a whole profile, and the lifting square tube is also connected to the piston rod of the cylinder arranged at intervals.

[0019] By adopting the above technical solution, buffer plate one is connected to the cylinder and linear guide rail, while buffer plate two is not connected to the cylinder and linear guide rail, saving the number of cylinders and linear guide rails, while also achieving the corresponding purpose; the lifting square tube is a single profile, ensuring that the lifting plates on it rise and fall simultaneously, and the problem of synchronizing multiple cylinders is solved by the overall rigidity of the lifting square tube and the strength of the linear guide rail.

[0020] Furthermore, the frame is also equipped with a conveying mechanism, which includes a conveying motor, a chain, and multiple conveying rollers. The conveying motor is connected to the frame, and the output shaft of the conveying motor is connected to one of the conveying rollers via a chain. Adjacent conveying rollers are also connected via chains. The conveying rollers are provided with multiple V-grooves, each V-groove facing the opening of the fixed feeding plate of the material distribution mechanism. The conveying rollers are angled relative to the axial direction of the circular tube during conveying.

[0021] By adopting the above technical solution, the conveyor motor can drive the chain and then drive the conveyor roller to rotate. Each V-groove is directly opposite the opening of the fixed feeding plate of the material distribution mechanism, so that the round tube can enter the V-groove when it falls. The conveyor roller is set at an angle to the axial direction of the round tube during conveying. Through this setting, the round tube can be rotated around the axis of the round tube during conveying, which facilitates the subsequent process of 360° operation on the round tube.

[0022] In summary, compared with the prior art, the beneficial effects of the above technical solution are: (1) By setting grooves of different positions, sizes, angles and quantities on the push plate, and by having the grooves cooperate with the cam bearing follower on the connecting mechanism, the independent control of material distribution at different workstations can be achieved by one power source, so as to realize the feeding, waiting and direct rolling of round tubes at the corresponding workstations. (2) A cam bearing follower of the connecting mechanism is located in the follower plate of the material distribution mechanism so that when the connecting mechanism moves, it pushes the follower plate to rotate around the rotating shaft. The rotating shaft drives the change of the angle of the rotating baffle, and finally realizes the feeding, waiting and direct rolling of the round tube at the corresponding station. (3) By setting up a feeding mechanism, the buffer plate can be used to store the round tubes completed in the previous process. When the piston rod of the cylinder extends, the lifting square tube moves upward along the linear guide under the drive of the piston rod of the cylinder, thereby driving the lifting plate to lift the heat exchange round tube. The lifting tube lifts the round tube from the buffer plate into the distributing mechanism, thereby realizing the feeding mechanism to deliver the round tubes completed in the previous process to the distributing mechanism. (4) By setting up a conveying mechanism, the conveying motor can drive the chain and then drive the conveying roller to rotate. Each V-groove is directly opposite the opening of the fixed feeding plate of the material distribution mechanism, so that the round tube can enter the V-groove when it falls. The conveying roller is set at an angle to the axial direction of the round tube during conveying. Through this setting, the round tube can be rotated around the axis of the round tube during conveying, which is convenient for subsequent processes to operate the round tube 360°.

[0025] The following is in conjunction with the appendix Figure 1-9 The principles and features of the present invention are described, and the examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0026] This invention discloses a single-power, multi-station material conveying system.

[0027] Reference Figure 1-9A single-power multi-station material distribution and conveying system includes a frame 1, on which a feeding mechanism 11, a pusher plate 2, a connecting mechanism 5, a material distribution mechanism 6, and a conveying mechanism 12 are mounted. The feeding mechanism 11 is used to convey the round tubes 13 that have completed the previous process to the material distribution mechanism 6. The pusher plate 2 has grooves 4, and the connecting mechanism 5 is connected to the pusher plate 2 through the grooves 4, and the connecting mechanism 5 is also connected to the material distribution mechanism 6. When the pusher plate 2 moves, it can drive the connecting mechanism 5 to move under the push of the grooves 4. At the same time, the movement of the connecting mechanism 5 can drive the material distribution mechanism 6 to control the station status as unloading (a), waiting (b), or directly rolling (c). By setting grooves 4 with different positions, sizes, angles, and numbers on the pusher plate 2, the system can meet the needs of independent control of different stations with a single power source, so as to realize the unloading (a), waiting (b), and direct rolling (c) of the round tubes 13 at the corresponding stations. Finally, the conveying mechanism 12 conveys the round tubes 13, which is convenient for subsequent processes to operate on the round tubes 13.

[0028] The feeding mechanism 11 includes a buffer plate 111, a cylinder 112, a lifting square tube 113, a lifting plate 114, a connecting plate 115, and a linear guide rail 116. The buffer plate 111 is connected to the frame 1 and is used to store the round tube 13 completed in the previous process. The cylinder seat of the cylinder 112 is connected to the buffer plate 111, and the piston rod is connected to the lifting square tube 113. The linear guide rail 116 is connected to the buffer plate 111. The bottom of the lifting square tube 113 is slidably connected to the linear guide rail 116 through the lower end of the connecting plate 115. Multiple lifting plates 114 are connected along the length of the lifting square tube 113. When the piston rod of cylinder 112 extends, the lifting square tube 113 moves upward along the linear guide rail 116 under the drive of the piston rod of cylinder 112, thereby driving the lifting plate 114 to lift the heat exchange round tube 13. The lifting plate 114 lifts the round tube 13 from the buffer plate 111 into the material distribution mechanism 6, thereby realizing the feeding mechanism 11 to convey the round tube 13 that has completed the previous process to the material distribution mechanism 6.

[0029] The buffer plate 111 has two types: buffer plate one 1111 and buffer plate two 1112. Buffer plate one 1111 and buffer plate two 1112 are arranged alternately. Buffer plate one 1111 is connected to cylinder 112 and linear guide rail 116, while buffer plate two 1112 is not connected to cylinder 112 and linear guide rail 116, thus saving the number of cylinders 112 and linear guide rails 116 while still achieving the corresponding purpose. The lifting square tube 113 is a single profile and is connected to the piston rods of the spaced-apart cylinders 112, ensuring that the lifting plates 114 above rise and fall simultaneously. The overall rigidity of the lifting square tube 113 and the strength of the linear guide rail 116 solve the synchronization problem of multiple cylinders 112.

[0030] A base plate 8 is fixedly mounted on the frame 1, and a first guide rail 9 is fixedly mounted on the base plate 8. The first guide rail 9 is arranged along the length direction of the circular tube 13 workpiece. A motor 3 is fixedly mounted on the push plate 2 to drive the push plate 2 to move. The motor 3 drives the push plate 2 to move along the first guide rail 9 through a gear and rack, so that the push plate 2 is connected to the base plate 8 through the first guide rail 9. A second guide rail 10 is fixedly mounted on the base plate 8, and the connecting mechanism 5 is connected to the base plate 8 through the second guide rail 10.

[0031] The connecting mechanism 5 includes a connecting rod 51 and two cam bearing followers 52 at a 90° angle. One cam bearing follower 52 is located in the groove 4 of the push plate 2 and moves the connecting mechanism 5 under the push of the groove 4; the other cam bearing follower 52 is located in the material distribution mechanism 6. The motor 3 drives the push plate 2 to move. According to the requirements of the workstation (a), waiting (b), or directly rolling over (c), one or more grooves 4 of different sizes and angles are opened at different positions on the push plate 2. During the movement of the push plate 2, the cam bearing follower 52 located in the groove 4 of the push plate 2 on the connecting mechanism 5 can move the connecting mechanism 5 under the push of the groove 4. At the same time, since the other cam bearing follower 52 of the connecting mechanism 5 is located in the material distribution mechanism 6, the movement of the connecting mechanism 5 can push the material distribution mechanism 6 to control the workstation state to material a, waiting b, or directly rolling over c.

[0032] The material distribution mechanism 6 includes a follower plate 61, a rotating shaft 62, a fixed feeding plate 63, and multiple sets of spaced rotating baffles 64. Both the follower plate 61 and the rotating baffles 64 are fixed to the rotating shaft 62, which is rotatably connected to the fixed feeding plate 63. The fixed feeding plate 63 has an opening 7 for feeding stations. Driven by the connecting mechanism 5, the follower plate 61 rotates, causing the rotating shaft 62 to rotate around its axis, which in turn causes the rotating baffles 64 to rotate.

[0033] The rotating shaft 62 is rotatably connected to the fixed feed plate 63 via bearings to reduce the friction between the rotating shaft 62 and the fixed feed plate 63, which is beneficial to the rotation of the rotating shaft 62. The rotating baffle 64 and the fixed feed plate 63 are offset along the length of the rotating shaft 62, so that the rotation process of the rotating baffle 64 does not interfere with the fixed feed plate 63.

[0034] When the rotating baffle 64 is in its initial position, its tilt angle is the same as that of the fixed feed plate 63, and it covers the opening 7 on the fixed feed plate 63. This allows the round tube 13 to roll past the fixed feed plate 63 and the rotating baffle 64 to the next feeding station of the fixed feed plate 63, thus achieving direct rolling (c) of the round tube 13 at the corresponding station. When the rotating baffle 64 rotates to a tilt angle θ exceeding that of the fixed feed plate 63, and the round tube 13 can abut against the rotating baffle 64, the round tube 13 waits (b) at the corresponding station. When the rotating baffle 64 rotates to a tilt angle θ exceeding that of the fixed feed plate 63, and the round tube 13 can pass through the distance between the rotating baffle 64 and the fixed feed plate 63, the round tube 13 is fed (a) at the corresponding station. In summary, by changing the angle of the rotating baffle 64 at different feeding stations, the round tube 13 achieves feeding (a), waiting (b), and direct rolling (c) at the corresponding station.

[0035] A cam bearing follower 52 of the connecting mechanism 5 is located inside the follower plate 61 of the material distribution mechanism 6, so that when the connecting mechanism 5 moves, it pushes the follower plate 61 to rotate around the rotating shaft 62. The rotating shaft 62 drives the change of the angle of the rotating baffle 64, ultimately realizing the unloading a, waiting b, and direct rolling c of the round tube 13 at the corresponding work station.

[0036] Each unloading station has an independent connecting mechanism 5, a follower plate 61, a rotating shaft 62, and a rotating baffle 64. By setting grooves 4 in different positions, sizes, angles, and quantities on the push plate 2, and through the interaction of these grooves with the cam bearing follower 52 on the connecting mechanism 5, a single power source can independently control the material distribution at different stations. This allows the round tube 13 to be unloaded (a), waited (b), or rolled directly (c) at the corresponding station. After unloading (a), the round tube 13 needs to be conveyed by the conveying mechanism 12 to facilitate subsequent processes.

[0037] The conveying mechanism 12 includes a conveying motor 121, a chain 122, and multiple conveying rollers 123. The conveying motor 121 is connected to the frame 1, and the output shaft of the conveying motor 121 is connected to one of the conveying rollers 123 via the chain 122. Adjacent conveying rollers 123 are also connected via chains 122, allowing the conveying motor 121 to drive the chain 122, which in turn drives the conveying rollers 123 to rotate. The conveying rollers 123 are provided with multiple V-grooves 1231, each V-groove 1231 facing the opening 7 of the fixed feed plate 63 of the material distribution mechanism 6, allowing the round tube 13 to enter the V-groove 1231 when it falls. The conveying rollers 123 and the axial direction of the round tube 13 during conveying are set at an angle θ. This setting allows the round tube 13 to rotate around its axis during conveying, facilitating 360° operation of the round tube 13 in subsequent processes.

[0038] The implementation principle of a single-power multi-station material distribution and conveying system according to an embodiment of the present invention is as follows: The buffer plate 111 of the feeding mechanism 11 is used to store the round tube 13 completed in the previous process. When the piston rod of the cylinder 112 extends, the lifting square tube 113 moves upward along the linear guide rail 116 under the drive of the piston rod of the cylinder 112, thereby driving the lifting plate 114 to lift the heat exchange round tube 13. The lifting plate 114 lifts the round tube 13 from the buffer plate 111 into the material distribution mechanism 6, thereby realizing the feeding mechanism 11 conveying the round tube 13 completed in the previous process to the material distribution mechanism 6; the motor 3 drives the push plate 2 to move. During the movement of the push plate 2, the cam bearing follower 52 located in the groove 4 of the push plate 2 on the connecting mechanism 5 can drive the connecting mechanism under the push of the groove 4. As the connecting mechanism 5 moves, the other cam bearing follower 52 of the connecting mechanism 5 is located in the follower plate 61 of the material distribution mechanism 6. When the connecting mechanism 5 moves, it pushes the follower plate 61 to rotate around the rotating shaft 62. The rotating shaft 62 drives the angle of the rotating baffle 64 to change, and finally realizes the round tube 13 in the corresponding work station for unloading a, waiting b, and direct rolling c. When the round tube 13 is unloaded a, it can just enter the V-groove 1231 on the conveying roller 123. The conveying motor 121 drives the chain 122 and then drives the conveying roller 123 to rotate. Since the conveying roller 123 and the axial direction of the round tube 13 are set at an angle θ, the round tube 13 rotates around the axis of the round tube 13 during conveying, which facilitates the subsequent process to perform 360° operation on the round tube 13.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
