Description

Technical Field

[0001] The invention relates to the technical field of angle steel processing, and in particular to a device for synchronous processing of angle steel with double-layer roller transmission and turnover. Background Art

[0002] During the processing of angle steel, a single-layer roller conveyor combined with manual or semi-automatic flipping is typically used to complete the transmission, processing, or reversing of the angle steel. However, this processing method is prone to speed mismatches due to the different drive systems used to control the transmission and flipping actions. This can cause the angle steel to shift, get stuck, or even fall during the flipping process, thus affecting processing accuracy and safety. At the same time, the single-layer roller structure cannot fully utilize the factory space, and the return transport usually requires additional equipment or manual handling, which leads to longer production cycles, making it difficult to meet the needs of large-scale, high-speed processing, and increasing production costs.

[0003] Therefore, there is an urgent need for a double-layer roller transmission and flipping synchronous processing device for angle steel to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-layer roller transmission and flipping synchronous processing device for angle steel. By integrating a closed-loop roller system, a flipping mechanism and a synchronous control system, a device for processing angle steel with high-precision synchronization of transmission and flipping, a high degree of automation and high space utilization is realized, so as to improve production efficiency, reduce manual intervention and ensure processing quality, thereby effectively solving the above-mentioned problems.

[0005] Technical solution: Angle steel double-layer roller conveyor and turning synchronous processing device, including a frame, and

[0006] The upper roller conveyor mechanism and the lower roller conveyor mechanism are arranged on the frame, are arranged horizontally and parallel to each other, and have opposite conveying directions;

[0007] A turning mechanism is provided at the connecting end of the upper roller conveyor mechanism and the lower roller conveyor mechanism, and is used to turn the angle steel from the upper roller conveyor to the lower roller conveyor;

[0008] Synchronous control system controls the synchronous operation of roller conveying and turning action through electrical connection.

[0009] In a further embodiment, the upper roller conveyor mechanism and the lower roller conveyor mechanism have the same structure, and both include a drive motor, a transmission chain and a plurality of rollers;

[0010] The roller is linked to the drive motor through a transmission chain, and the surface of the roller is provided with anti-slip grooves;

[0011] The distance between two adjacent rollers is less than half of the minimum length of the angle steel.

[0012] Through the above technical solution, the stability of angle steel transmission is enhanced and slipping is prevented; at the same time, the roller spacing limit ensures that the short angle steel is always supported by at least two rollers, avoiding tilting or jamming during transportation.

[0013] In a further embodiment, the transmission chain is provided with a plurality of centering clamping devices spaced between the rollers; the centering clamping devices include:

[0014] The bearing plate has sliding bars symmetrically mounted on its bottom end, and the sliding bars are fixedly connected to the transmission chain;

[0015] A fixing seat, mounted on the bearing plate;

[0016] The fixing block and the clamping block are arranged opposite to each other and symmetrically mounted on the bearing plate;

[0017] a guide post connecting the fixing seat and the clamping block and used for guiding the clamping block to move toward the fixing block;

[0018] The spring is arranged on the outer periphery of the guide column and is used for providing a clamping force to center the angle steel.

[0019] Through the above technical solution, the angle steel can be flexibly clamped during transportation to avoid damage to the angle steel surface, eliminate the risk of deviation, and ensure processing accuracy. In addition, since the sliding bar is fixedly connected to the chain, follow-up positioning can be achieved with high synchronization and no additional drive is required.

[0020] In a further embodiment, the flipping mechanism includes a three-axis robotic arm, a gripping robot, and a servo drive unit;

[0021] An elastic buffer layer is provided on the inner side of the clamping manipulator, and an anti-slip pattern is provided on the surface of the elastic buffer layer.

[0022] Through the above technical solution, the three-axis robotic arm cooperates with the servo drive unit to use the clamping robot to achieve high-precision flipping. At the same time, the elastic buffer layer and anti-slip texture protect the surface integrity of the angle steel and enhance the clamping stability.

[0023] In a further embodiment, both ends of the upper roller conveyor mechanism and the lower roller conveyor mechanism are equipped with a lifting device, and the lifting device includes:

[0024] A support base, fixed on the frame, for supporting other parts;

[0025] A cylinder is installed below the support base and is used to provide power for upward lifting;

[0026] a moving block connected to the output end of the cylinder;

[0027] A fixed plate is installed at both ends of the roller conveyor mechanism, with its upper surface being located at the same horizontal plane as the upper surface of the roller, and a plurality of through holes are opened on the fixed plate;

[0028] The lifting plate is fixed on the upper end of the moving block, and a plurality of protruding blocks adapted to the through holes are fixed on the upper surface.

[0029] Through the above technical solution, the cylinder drives the moving block and the lifting plate to move up and down, so as to achieve a smooth transition of the angle steel at the end of the roller table, avoiding direct falling and deformation. At the same time, the cooperation between the through hole and the raised block can prevent the angle steel from shifting during the lifting process.

[0030] In a further embodiment, the raised block has a magnetic attraction function.

[0031] The above technical solution can prevent the angle steel from sliding during jacking.

[0032] In a further embodiment, the synchronization control system comprises:

[0033] PLC controller for logic control;

[0034] Encoder, used to monitor the roller speed in real time;

[0035] A photoelectric sensor is installed at the transmission direction of the upper roller conveyor mechanism and the lower roller conveyor mechanism, and is used to detect the angle steel position signal.

[0036] Through the above technical solution, closed-loop control and real-time monitoring are achieved to ensure strict synchronization of transmission and flipping, avoid accumulation or idling of angle steel, and improve system reliability.

[0037] In a further embodiment, a speed compensation module is further included, which is used to automatically adjust the angular velocity of the turnover mechanism or the speed of the roller conveyor when it is detected that the speed deviation exceeds a set threshold.

[0038] The above technical solution can solve the synchronization error caused by load changes or mechanical wear and ensure the consistency of processing rhythm.

[0039] In a further embodiment, a safety protection device is further included, which includes gratings distributed along both sides of the roller conveyor to form a monitoring area; and an emergency stop button and an audible and visual alarm arranged on the frame.

[0041] In a further embodiment, the lifting stroke of the lifting plate matches the thickness of the angle steel.

[0042] Through the above technical solution, it is ensured that the lifting height can not only separate the angle steel and the roller, but also avoid excessive lifting that causes unstable center of gravity. It is adaptable to angle steels of different specifications and has a wide range of applications.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] like Figures 1 to 4As shown, the present application provides a device for synchronous processing of angle steel with double-layer roller conveying and turning, hereinafter referred to as "the device". In the embodiment, the device includes a frame 1, an upper roller conveying mechanism 3, a lower roller conveying mechanism 2, a turning mechanism 4 and a synchronous control system.

[0054] The upper roller conveyor mechanism 3 and the lower roller conveyor mechanism 2 are arranged horizontally and parallel to each other on the frame 1, reducing floor space. They share the same structure but operate in opposite directions. Each roller conveyor consists of a drive motor 31, a transmission chain, and several rollers. The rollers are designed with anti-skid grooves to enhance the stability of angle steel transmission and prevent slipping. The distance between adjacent rollers is less than half the minimum length of the angle steel, ensuring stable support for short angle steels. When the drive motor 31 is running, it drives the transmission chain, which in turn drives the rollers.

[0055] The flip mechanism 4, located at the junction of the upper roller conveyor mechanism 3 and the lower roller conveyor mechanism 2, flips the angle steel from the upper roller conveyor to the lower roller conveyor. It consists of a three-axis robotic arm 41, a gripping manipulator 42, and a servo drive unit. The three-axis robotic arm 41, in conjunction with the servo drive unit, achieves high-precision flipping, adapting to complex angle adjustments, while the gripping manipulator 42 grips the angle steel.

[0056] See Figure 4 As a preferred solution, the inner side of the clamping manipulator 42 is provided with an elastic buffer layer 421, and the surface of the elastic buffer layer 421 is provided with anti-slip grooves, which can protect the surface integrity of the angle steel and enhance the clamping stability.

[0057] As a preferred solution, the servo drive unit adopts an absolute encoder servo motor, whose rotation positioning accuracy is ≤0.1°, which improves positioning accuracy, reduces synchronization error, and improves the performance indicators of the entire device.

[0058] Specifically, when the servo drive unit is running, it drives the three-axis robotic arm 41 to achieve free movement in three-dimensional space, thereby driving the clamping robot 42 connected to the three-axis robotic arm 41 to achieve high-precision flipping, and the clamping robot 42 uses its own motor to clamp the diagonal steel.

[0059] The synchronous control system controls the synchronous operation of roller conveying and flipping actions through electrical connections, and includes a PLC controller, an encoder and a photoelectric sensor, wherein the PLC controller is used for logic control; the encoder is used to monitor the roller linear speed in real time; the photoelectric sensor is installed on the upper roller conveying mechanism 3 and the transmission direction of the roller conveying mechanism to detect the angle steel position signal.

[0060] As a preferred solution, the synchronous control system also includes a speed compensation module, which is used to automatically adjust the angular velocity of the flipping mechanism 4 or the speed of the roller conveyor when it is detected that the speed deviation exceeds the set threshold, so as to solve the synchronization error caused by load changes or mechanical wear and ensure the consistency of the processing rhythm.

[0061] Based on the above embodiment, in order to prevent the angle steel from deviating during the transmission process, the present application sets a number of centering clamping devices 6 on the transmission chain, which are spaced and distributed between the rollers. Figure 2 The centering clamping device 6 includes a supporting plate 61, a fixed seat 62, a spring 64, a guide column 63, a fixed block 66, and a clamping block 65. A sliding bar 611 is symmetrically mounted on the bottom end of the supporting plate 61, and the sliding bar 611 is fixedly connected to the transmission chain; the fixed seat 62 is mounted on the supporting plate 61; the fixed block 66 and the clamping block 65 are arranged opposite each other and symmetrically mounted on the supporting plate 61; the guide column 63 connects the fixed seat 62 and the clamping block 65, and is used to guide the clamping block 65 to move toward the fixed block 66; the spring 64 is arranged on the periphery of the guide column 63, and is used to provide a clamping force to center the angle steel; when the angle steel enters the roller transmission mechanism, the spring 64 applies force to the clamping block 65 along the direction of the guide column 63, causing the clamping block 65 to move toward the fixed block 66, clamping the angle steel and centering the angle steel, thereby facilitating the subsequent operation of the flipping mechanism 4.

[0062] In order to achieve a smooth transition of the angle steel at the connecting end of the upper roller conveyor mechanism 3 and the lower roller conveyor mechanism 2, the present application installs a lifting device 7 at both ends of the roller conveyor mechanism, see Figure 3 The lifting device 7 includes a support base 71, a cylinder 72, a moving block 73 and a fixed plate 75, wherein the support base 71 is fixed on the frame 1 for supporting other parts; the cylinder 72 is installed below the support base 71 for providing power for upward lifting; the moving block 73 is connected to the output end of the cylinder 72; the fixed plate 75 is installed at the end of the roller conveyor mechanism, and its upper surface is located at the same horizontal plane as the upper surface of the roller, and a number of through holes are opened on the fixed plate 75; the lifting plate 74 is fixed to the upper end of the moving block 73, and a number of protruding blocks 741 adapted to the through holes are fixed on the upper surface. The protruding blocks 741 have a magnetic suction function to absorb the angle steel to prevent the angle steel from sliding during lifting. When the cylinder 72 drives the moving block 73 to move upward in a straight line, the moving block 73 drives the lifting plate 74 to move upward, and the protruding blocks 741 on the lifting plate 74 pass through the through holes.

[0063] As a preferred solution, the lifting stroke of the lifting plate 74 matches the thickness of the angle steel, ensuring that the lifting height can separate the angle steel and the roller while avoiding excessive lifting that causes an unstable center of gravity.

[0064] Based on the above embodiments, in order to increase the safety of the operation of the device, the present application also includes a safety protection device, which consists of a grating, an emergency stop button 52 and an audible and visual alarm 51, wherein the grating is arranged along both sides of the roller to form a detection area, and the emergency stop button 52 and the audible and visual alarm 51 are both set on the frame 1, which can quickly warn of abnormalities, trigger an emergency stop in time to prevent collisions, and avoid personal injury.

[0065] The specific working process is as follows: turn on the two drive motors 31, and drive the rollers to rotate through the transmission chain, and the transmission directions of the upper and lower roller conveyor mechanisms are opposite. The angle steel is placed on the load-bearing plate 61, and the clamping block 65 approaches the fixed block 66 along the guide column 63 through the spring 64, thereby clamping the angle steel to prevent it from deflecting during the conveying process until the angle steel is conveyed to the connecting end of the two roller conveyor mechanisms. At this time, the cylinder 72 in the jacking device 7 starts to work, driving the moving block 73 and the jacking plate 74 installed on the moving block 73 to move upward until the protruding block 741 on the jacking plate 74 passes through the through hole on the fixed plate 75. At the same time, the servo drive unit runs, controlling the three-axis robot 41 to drive the clamping robot 42 to grab the angle steel. The three-axis robot 41 flips 180° according to the PLC instruction and is placed on the roller conveyor mechanism of another layer. During the whole process, the encoder monitors the roller speed in real time, the photoelectric sensor detects the position of the angle steel, and the speed compensation module dynamically adjusts the deviation. When the grating detects an abnormality during the entire conveying process, an emergency stop is triggered and the sound and light alarm 51 is used to warn.

[0066] Compared with the prior art, this application has the following obvious advantages:

[0067] Continuous processing is achieved through double-layer reverse rollers and high-precision turning mechanism 4, which improves efficiency;

[0068] Synchronous control system and speed compensation module ensure that transmission or flipping action errors are greatly reduced;

[0069] The arrangement of the centering clamping mechanism and the jacking mechanism effectively prevents the angle steel from being offset or damaged. The above content is a detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be regarded as falling within the scope of protection of the present invention.
