Description

Technical Field

[0001] This utility model relates to the field of logistics equipment conveyor technology, specifically a cylindrical pneumatic conveying pipeline diversion device. Background Technology

[0002] Currently, merging / diverting hoists are mainly used for lifting or lowering goods with small height differences. They can support multiple inlets or outlets simultaneously, performing both lifting and diverting of goods. Traditional merging / diverting hoists, due to their unsuitability for very small height differences between inlets and outlets, have eliminated the receiving structure compared to floor hoists, instead using a brake motor for stopping. Because the brake motor uses brake pads for friction braking, the braking torque is essentially constant. Therefore, the braking distance is directly proportional to the load, and the faster the speed, the greater the error in braking distance. Generally, to reduce this error, it is often necessary to replace it with a high-power motor with a larger braking torque or a specially designed motor, which significantly increases costs.

[0003] Meanwhile, the current merging / diverting elevators use a motor-chain lifting system. Since the motor speed is constant, adjusting its speed requires a frequency converter or a gearbox. If different speeds are desired at different stages of the merging / diverting elevator's movement, a CNC frequency converter or an automatic transmission is needed, both of which are relatively expensive.

[0004] To address this, the existing technical solution disclosed in patent number 2009202970990 is a pneumatic high-speed merging / diverting elevator, particularly relating to a frame. The frame houses a lifting power unit and a horizontal power tray device. The frame has an inlet and an outlet. The lifting power unit consists of a cylinder, a guide rod, and a floating device. A slide is connected to the guide rod and rigidly connected to the horizontal power tray device. The cylinder is connected to the floating device, which in turn is connected to the horizontal power tray device. The cylinder is connected to a matching pneumatic system. The horizontal power tray device includes a bracket with an electric roller mounted on it, and a belt wound around the electric roller. However, the above technical solution has the following drawbacks:

[0005] While a structure employing a shock absorber can provide additional drag as the cylinder piston approaches its end point, this setup remains costly and has limited adaptability to different loads. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-3As shown, a pneumatic conveying pipeline diversion device for cylindrical containers includes: a diversion conveying frame 1, a conveying line 2 on the diversion conveying frame 1, an obstruction detection sensor 3 at the discharge port of the conveying line 2, a pneumatic transfer platform 4 at the obstruction detection sensor 3, the pneumatic transfer platform 4 extending horizontally along the conveying direction of the conveying line 2 and connected to a conveying line 8, and a diversion line 9 perpendicular to the conveying direction of the conveying line 2 on the diversion conveying frame 1, with a vertical height difference between the diversion line 9 and the pneumatic transfer platform 4. That is, the pneumatic transfer platform 4, located on the diversion conveying frame 1 and between the conveying lines 2, enables the transfer of materials and the connection between the conveying lines. The pneumatic transfer platform 4 is pushed by a cylinder 43 and forms a shape towards the diversion line. A 9-inch inclined unloading platform is provided. A cylinder 43 is located at the bottom of the pneumatic transfer platform 4 near the diversion line 9. The end of the pneumatic transfer platform 4 opposite to the cylinder 43 is rotatably mounted on the diversion conveyor frame 1. The cylinder 43 is initially set to extend outwards, and the pneumatic transfer platform 4 extends outwards from the side facing the diversion line 9 to the outside of the transport line 2 and the conveyor line 8 (extending at least 1 / 3 of its end face length). When it is necessary to push the material to the diversion line 9, the cylinder 43 retracts its piston downwards to form an inclined surface of the pneumatic transfer platform 4 facing the diversion line 9. The end face of the pneumatic transfer platform 4 abuts against the end wall of the transport line 2 and the conveyor line 8. Rotating rollers 42 are rotatably arranged on the pneumatic transfer platform 4. The rotating rollers 42 are cylindrical, and the conveying and diversion device provided in this application can also be applied to the conveying and transporting of cylindrical equipment.

[0021] Working principle: Material detection and start-up:

[0022] As the material moves forward on conveyor line 2, the obstruction detection sensor 3 monitors the material's position in real time. When the sensor detects that the material has reached the designated position, it sends a signal to the control system, which then activates the pneumatic transfer table 4 upon receiving the signal.

[0023] Material transfer:

[0024] The pneumatic transfer table 4, propelled by the cylinder 43, forms a feeding platform inclined towards the diversion line 9. At this time, the end face of the pneumatic transfer table 4 abuts against the end walls of the transport line 2 and the conveyor line 8, ensuring that the material can be smoothly transferred from the transport line 2 to the pneumatic transfer table 4. Simultaneously, the rotation of the rotating roller 42 reduces the friction and resistance of the material during the transfer process.

[0025] Material is conveyed to distribution line 9:

[0026] As the pneumatic transfer table 4 tilts, the material slides along the unloading platform towards the diversion line 9 under the force of gravity and the push of the cylinder 43. Since the diversion line 9 is perpendicular to the transport line 2 in the same horizontal plane, the material can smoothly transition onto the diversion line 9 and continue to be conveyed forward.

[0027] Reset and wait:

[0028] After the material is successfully transferred to the diversion line 9, the pneumatic transfer table 4 returns to its initial position under the control of the control system, awaiting the arrival of the next batch of material. Simultaneously, the obstruction detection sensor 3 continues to monitor the material status on the transport line 2, ensuring the continuity and stability of the entire conveying process.

[0029] In summary, this cylindrical pneumatic conveying pipeline diversion device, through its ingenious design, achieves efficient and automated material transfer between transport line 2 and diversion line 9, improving production efficiency, reducing the risk of material damage, and saving space.

[0030] This technical solution uses a mounting frame 41 to mount one end of the rotating roller 42 at the end of the transport line 2 and the other end at the end of the conveyor line 8, ensuring a smooth transition of materials during transfer. Simultaneously, the rotation direction of the rotating roller 42 is consistent with the conveying direction of the transport line 2, which helps reduce friction and resistance during material transfer and improves transfer efficiency. The pneumatic transfer table 4 includes a mounting frame 41, with one end mounted at the end of the transport line 2 and the other end at the end of the conveyor line 8, allowing materials to be smoothly transferred from the transport line 2 to the pneumatic transfer table 4 and then further transferred to the conveyor line 8, achieving smooth material transfer. The rotation direction of the rotating roller 42 is consistent with the conveying direction of the transport line 2. A cylinder 43 is located at the bottom of the mounting frame 41 to tilt the mounting frame 41 towards the diversion line 9 to optimize the transfer path and reduce resistance.

[0031] The mounting frame 41 is also equipped with a pneumatic pusher 5 that moves in the direction of the flow divider 9, further enhancing the transfer capacity of the pneumatic transfer table 4. The pneumatic pusher 5 can move in the direction of the flow divider 9, pushing the material to transition more smoothly onto the flow divider 9, reducing the jamming and accumulation of material during the transfer process.

[0032] The mounting frame 41 is equipped with a rotating wheel 7 at one end near the diversion line 9, allowing the mounting frame 41 to more flexibly adapt to the transmission direction of the diversion line 9 when transferring materials. This helps reduce the impact and vibration of materials during the transfer process, improving the smoothness of the transfer. The rotating wheel 7 is aligned with the transmission direction of the diversion line 9, and through the buffering effect of the rotating wheel 7, it reduces the impact and vibration of materials on the mounting frame 41 during the transfer process, helping to protect the materials and the transfer equipment.

[0033] The installation of the obstruction detection sensor 3 provides flexible position adjustment space. By adjusting the height of the lifting rod 6, the detection range and accuracy of the sensor can be optimized, the accuracy of material detection can be improved, and the height of the obstruction detector can be adjusted according to different materials. The lifting rod 6 is set at the discharge end of the actual conveyor line 2.

[0034] The obstruction detection sensor 3 includes an infrared emitter 31 and an infrared receiver 32. The infrared emitter 31 and the infrared receiver 32 are respectively fixed on the top of the corresponding lifting rod 6. The infrared receiver has the advantages of high detection sensitivity, fast response speed and strong anti-interference ability, and can accurately and reliably detect the presence and position of materials.

[0035] This application is mainly used for diverting and conveying material boxes of different sizes. It uses an obstruction sensor to detect the product. If the material box is lower than the obstruction sensor, the pneumatic platform is tilted. (This detection is controlled by an external controller. Since the conveying speed of the diverting conveyor 1 is consistent, and the material box conveying in this embodiment is set to uniform speed interval quantitative conveying, the controller can calculate the time it takes for the material to reach the pneumatic transfer table 4 by measuring the rotation speed of the servo motor on the diverting conveyor 1 through an encoder. Each time the obstruction sensor detects a material box, it records the data in the controller and restarts the timing. The controller determines whether the material box has been conveyed to the pneumatic transfer table 4 based on the recorded time. If the obstruction sensor does not detect the material box, the pneumatic push rod 5 in this embodiment is normally in a retracted state, and the piston rod end face of the pneumatic push rod 5 can be set as an inclined surface during actual operation. This embodiment mainly shows a flat piston rod, with the inclined surface tilted towards the conveyor line 8 and its cross-section enlarged. When the controller determines based on the timing, it controls the pneumatic push rod 5 to extend, so that the material slides into the diverting line 9.)

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
