Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a receiving device with buffer and anti-collision function. Background Technology

[0002] In the automated production process of pipes (such as steel pipes and aluminum pipes), after the beveling and cutting machine completes the cutting process, a receiving device is needed to receive, temporarily store, and orderly transport the pipes to avoid disorderly accumulation or surface damage. Traditional receiving devices typically consist of an adjustable tilting plate, a receiving trough, and a conveying mechanism. Their core function is to guide the cut pipes from a high position to the receiving station, and then transfer them to the next process via the conveying mechanism. Due to the heavy weight of the pipes (especially large-diameter metal pipes) and their strong inertial impact, the buffering performance and conveying stability of the receiving device directly affect production efficiency and product quality.

[0003] For example, an automatic receiving rack disclosed in Chinese Patent Publication No. CN109986123B includes a frame, a finished product collection box, a drive mechanism, a vertically arranged support mechanism, at least three vertical lifting mechanisms, and a material separation mechanism for distinguishing finished products and waste. The frame is elongated and includes a base frame and a panel fixedly connected to the base frame. The finished product collection box is located on one side of the frame, and the panel is inclined towards the side of the finished product collection box. The support mechanism includes a control device, at least three support components for clamping pipe fittings, and at least three lifting components for driving the support components to rise and fall. The number of support components is the same as the number of lifting components. The control device is connected to the input end of each lifting component, and the output end of the lifting component is connected to the support component. The support components are vertically slidably connected to the base frame through the lifting components. This automatic receiving rack can automatically screen finished products and waste.

[0004] However, the automatic receiving rack still has obvious defects in actual use: its finished product collection box is prone to being full in a short time due to its fixed capacity, requiring frequent shutdowns for replacement, which leads to interruption of the operation process and increased labor costs; at the same time, during the process of the pipes rolling from the support components to the finished product collection box, they not only collide directly with the box, but also impact each other due to disorderly stacking, which can easily cause scratches on the pipe surface or deformation at the ends, especially significantly affecting the yield of high-precision pipes such as thin-walled pipes and coated pipes.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a receiving device with buffer and anti-collision function to solve the above problems.

[0007] A receiving device with buffer and anti-collision function includes a support and a receiving rack. The support is equipped with a liftable lifting frame, and the upper end of the lifting frame is hinged to a flap. The lifting frame is also equipped with a pusher to drive the flap to adjust to different tilt angles. The receiving rack is equipped with a support plate with a receiving groove. The flap guides the pipe into the receiving groove by adjusting the tilt angle. A buffer pad is provided on the side of the receiving groove facing the flap. One end of the buffer pad is hinged to the support plate, and the other end is supported by an elastic element to achieve buffering. The receiving rack is also equipped with a conveying assembly. The conveying assembly includes a plurality of conveying rollers arranged along the length of the receiving groove and a belt drive device for driving all the conveying rollers to rotate synchronously. The support plate has clearance holes corresponding to the positions of the conveying rollers, so that the conveying rollers can protrude upward into the receiving groove to convey the pipe.

[0008] Specifically, the support frame is equipped with a lifting assembly, which includes a right-angle motor fixed to the support frame, a rotating shaft connected to the right-angle motor, a gear sleeved on the rotating shaft, and a rack meshing with the gear. The rack is fixed to the lifting frame in the vertical direction, and the lifting frame is driven to rise and fall through the meshing of the gear and the rack.

[0009] Specifically, the pusher is a cylinder, the body of the cylinder is hinged to the lifting frame, and the piston rod end of the cylinder is hinged to the bottom surface of the flip plate. The tilt angle of the flip plate is adjusted by extending and retracting the cylinder.

[0010] Specifically, the flap is equipped with several heavy-duty rollers, and the rolling direction of the heavy-duty rollers is perpendicular to the pipe guiding direction of the flap.

[0011] Specifically, the bottom of the bracket is provided with multiple adjustable leveling feet for adjusting the levelness of the bracket.

[0012] Specifically, the top surface of the buffer pad is a rough slope, and its inclination direction is consistent with the downward sliding direction of the pipe, which is used to slow down the downward sliding speed of the pipe and guide the pipe to the conveying roller.

[0013] Specifically, the conveying roller has a waist-shaped structure, with its central diameter being smaller than the diameters at both ends.

[0014] Specifically, the conveying assembly also includes a C-shaped frame and a rubber pad. The C-shaped frame is used to mount the conveying roller, and the rubber pad is located at the bottom of the C-shaped frame. The rubber pad is supported by the receiving frame to buffer the vibration of the conveying roller.

[0015] The beneficial effects of this utility model are:

[0016] This application discloses a receiving device with buffer and anti-collision function, including a bracket, a receiving frame, a liftable lifting frame, and a flap hinged to the upper end of the lifting frame. The flap is tilted at an angle by a pusher to guide the pipe into the receiving groove of the receiving frame. A hinged buffer pad is provided on the inlet side of the receiving groove, which achieves dynamic buffering through elastic support. A clearance hole is opened at the bottom of the groove for the conveying roller to protrude and receive the pipe. The conveying assembly consists of synchronously driven conveying rollers and a belt drive device, which, together with the waist-drum shaped roller structure, achieves centered guidance of the pipe. By adjusting the flap angle and linking it with the height of the lifting frame, it adapts to the sliding trajectory requirements of pipes of different specifications. After being decelerated by the buffer pad, the pipe is rolled and conveyed by the conveying roller, replacing the fixed receiving mode of the traditional collection box, avoiding frequent machine stops for box replacement and rigid collision damage. The dual effect of the elastic buffer structure and the waist-drum shaped roller effectively prevents scratches on the pipe surface, end deformation, and conveying deviation. At the same time, the shock-absorbing base reduces the vibration load of the equipment, extends the life of the transmission components, improves the receiving efficiency and yield of high-precision pipes, and meets the needs of continuous production.

[0022] This utility model provides a receiving device with a buffer and anti-collision function. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please refer to Figures 1 to 4 As shown, this embodiment discloses a receiving device with buffer and anti-collision function, including a bracket 1 and a receiving rack 2. The bracket 1 is provided with a liftable lifting frame 3. The upper end of the lifting frame 3 is hinged to a flip plate 4. The lifting frame 3 is also provided with a pusher 5 to drive the flip plate 4 to adjust to different tilt angles. The receiving rack 2 is provided with a support plate 6 with a receiving groove 7. The flip plate 4 guides the pipe into the receiving groove 7 by adjusting the tilt angle. The receiving groove 7 is provided with a buffer pad 8 on the side facing the flip plate 4. One end of the buffer pad 8 is hinged to the support plate 6, and the other end is supported by an elastic member 9 to achieve buffering. The receiving rack 2 is also provided with a conveying assembly 10. The conveying assembly 10 includes a plurality of conveying rollers 11 arranged along the length of the receiving groove 7 and a belt drive device 12 for driving all the conveying rollers 11 to rotate synchronously. The support plate 6 is provided with a clearance hole 13 at the position corresponding to the position of the conveying rollers 11, so that the conveying rollers 11 can protrude upward into the receiving groove 7 to convey the pipe.

[0025] The material receiving action in this embodiment is as follows: After the pipe is processed by the cutting equipment, it falls onto the surface of the flip plate 4. The flip plate 4 is adjusted to a preset tilt angle by the pusher 5, so that the pipe slides smoothly into the receiving groove 7 along the flip plate 4. When the pipe enters the receiving groove 7, it first contacts the buffer pad 8. The buffer pad 8 swings around the hinge point under the flexible support of the elastic member 9, dispersing and absorbing the impact force of the falling pipe. In addition, since a part of the conveying roller 11 protrudes into the receiving groove 7 through the clearance hole 13, the pipe rolls onto the conveying roller 11. The belt drive device 12 drives the conveying roller 11 to rotate synchronously, conveying the pipe to the next station.

[0026] In this embodiment, the receiving device, through the coordinated action of the conveying roller 11 and the belt drive device 12, realizes the conveying of pipes from the receiving trough 7 to the discharge end, completely replacing the traditional fixed finished product collection box, avoiding frequent shutdowns caused by the collection box being full, and significantly improving work efficiency. The hinged buffer structure composed of the buffer pad 8 and the elastic element 9 can disperse the impact force of the pipe sliding, prevent rigid collision between the pipe and the receiving trough 7 and the disorderly stacking impact between pipes, effectively protecting the bevel and surface integrity of high-precision pipes such as thin-walled pipes and coated pipes. A part of the conveying roller 11 protrudes into the receiving trough 7 through the avoidance hole 13, which can both support the pipe and prevent the pipe from directly hitting the surface of the pallet 6, and achieve smooth conveying through the rolling contact between the roller surface and the pipe, and prevent conveying deviation in conjunction with the waist drum-shaped roller structure. The lifting frame 3 adjusts the initial height of the flip plate 4, and the pusher 5 precisely controls the tilt angle of the flip plate 4 to adapt to the receiving needs of different specifications of pipes and reduce manual adjustment errors. The shock-absorbing base, consisting of the C-shaped frame 25 and the rubber pad 26, combined with the shock-dispersing effect of the buffer plate 8, reduces the vibration load on the receiving frame 2 and the conveying assembly 10, extends the service life of transmission components such as gears 17 and racks 18, and improves the overall durability of the equipment.

[0027] In a preferred embodiment, the support 1 is provided with a lifting assembly 14, which includes a right-angle motor 15 fixed to the support 1, a rotating shaft 16 connected to the right-angle motor 15, a gear 17 sleeved on the rotating shaft 16, and a rack 18 meshing with the gear 17. The rack 18 is fixed to the lifting frame 3 in the vertical direction, and the lifting frame 3 is driven to rise and fall through the meshing of the gear 17 and the rack 18. When the pipe specifications change and the receiving height needs to be adjusted, the right-angle motor 15 drives the rotating shaft 16 to rotate the gear 17. The gear 17 meshes with the rack 18, which is vertically fixed to the lifting frame 3, thereby precisely controlling the lifting height of the lifting frame 3. The lifting assembly 14 achieves stable lifting and height locking of the lifting frame 3 through the rigid transmission characteristics of the gear and rack meshing, avoiding the lag of traditional hydraulic lifting or the risk of skipping teeth in chain transmission. At the same time, the right-angle layout of the right-angle motor 15 and the gear 17 saves lateral space and is suitable for narrow workshop environments. The height adjustment of the lifting frame 3 can be linked to the initial tilt angle of the flip plate 4 to ensure that the trajectory is consistent when pipes of different lengths slide into the receiving groove 7, reducing repeated manual calibration and improving the switching efficiency and equipment adaptability of multi-specification pipe production.

[0028] In a preferred embodiment, the pusher 5 is a cylinder. The cylinder body is hinged to the lifting frame 3, and the piston rod end of the cylinder is hinged to the bottom surface of the flap 4. The tilt angle of the flap 4 is adjusted by extending and retracting the cylinder. In this embodiment, a cylinder is used as the pusher 5. The extension and retraction of the piston rod directly drives the flap 4 to rotate around the hinge point, realizing rapid adjustment of the tilt angle of the flap 4. The dual-degree-of-freedom design, with the cylinder body hinged to the lifting frame 3 and the piston rod end hinged to the bottom surface of the flap 4, allows the flap 4 to maintain the flexibility of angle adjustment during the lifting process of the lifting frame 3, avoiding structural interference caused by traditional single-axis drive. The linear output characteristics of the cylinder can accurately control the tilt angle of the flap 4, ensuring that pipes of different diameters slide into the receiving trough 7 with consistent landing points, reducing the risk of pipe offset or jamming. At the same time, the cylinder has a fast response speed and stable driving force, which is suitable for the dynamic adjustment needs of high-frequency, multi-specification pipe production.

[0029] In a preferred embodiment, the flap 4 is equipped with several heavy-duty rollers 20, the rolling direction of which is perpendicular to the pipe guiding direction of the flap 4. The heavy-duty rollers 20 on the surface of the flap 4, with their rolling direction perpendicular to the pipe guiding direction, allow the rollers 20 to roll freely along the pipe's movement direction as the pipe slides down the flap 4, significantly reducing the sliding friction resistance between the pipe and the flap 4 and preventing scratches on the pipe surface caused by friction. Simultaneously, the rolling action of the rollers 20 can adaptively adjust the pipe's sliding trajectory, preventing deviations in the sliding angle caused by a shift in the pipe's center of gravity, ensuring the pipe accurately slides into the buffer pad 8 area of ​​the receiving trough 7, further improving receiving stability and reducing manual intervention. The high load-bearing capacity of the heavy-duty rollers 20 also adapts to the receiving needs of large-diameter or high-density pipes, enhancing the device's versatility.

[0030] In a preferred embodiment, the bottom of the support 1 is provided with multiple adjustable leveling feet 21 for adjusting the levelness of the support 1. Through the independent adjustment of the adjustable leveling feet 21, the support 1 can be quickly adjusted to a level state under different ground conditions, ensuring the overall stability of the receiving device.

[0031] In a preferred embodiment, the top surface of the buffer pad 8 is a rough inclined surface 22, the inclination direction of which is consistent with the downward direction of the pipe. This is used to slow down the downward speed of the pipe and guide the pipe to the conveyor roller 11. The frictional resistance of the inclined surface gradually slows down the downward speed of the pipe, avoiding the pipe from directly impacting the conveyor roller 11 due to inertial impact and causing end deformation. The rough surface further increases the coefficient of friction, and together with the elastic support of the elastic element 9, forms a dynamic buffer, so that the pipe smoothly transitions to the surface of the conveyor roller 11 during the deceleration process. The inclined surface guides the pipe to ensure that the pipe axis is parallel to the arrangement direction of the conveyor roller 11, preventing the pipe from deviating or getting stuck.

[0032] In a preferred embodiment, the conveying roller 11 has a drum-shaped structure, with its central diameter being smaller than the diameters at both ends. This structure allows the pipe to be guided by the roller's curvature during conveying, automatically converging towards the center of the roller body, effectively preventing lateral rolling of the pipe due to inertia or shift in the center of gravity.

[0033] In a preferred embodiment, the conveying assembly 10 further includes a C-shaped frame 23 and a rubber pad 24. The C-shaped frame 23 is used to mount the conveying roller 11, and the rubber pad 24 is located at the bottom of the C-shaped frame 23. The rubber pad 24 is supported by the receiving frame 2 to buffer the vibration of the conveying roller 11. The C-shaped frame 23 provides a stable mounting base for the conveying roller 11 through its integral structure. The rubber pad 24 at its bottom absorbs the vibration energy of the conveying roller 11 during operation through elastic deformation, preventing the vibration from being transmitted to precision transmission components such as the gear 17 and rack 18 through the receiving frame 2, and reducing the risk of bolt loosening or bearing wear caused by long-term vibration. The combination of the rigid support of the rubber pad 24 and the C-shaped frame 23 not only ensures the driving stability of the conveying roller 11, but also reduces the minor vibration when the pipe comes into contact with the conveying roller 11 through flexible buffering, preventing friction scratches on the surface of the pipe caused by high-frequency micro-vibration, and reducing the operating noise of the equipment.

[0034] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
