Description

Technical Field

[0001] This invention relates to the field of cable reel manufacturing equipment technology, specifically to a fully automated intelligent production line for the outer ring steel of a cable reel. Background Technology

[0002] Cable reels are indispensable load-bearing devices in cable manufacturing and transportation. Their outer ring is typically made of C-shaped steel through cold bending and coiling. Currently, domestic cable reel manufacturers generally use traditional manual feeding methods, which involve using overhead cranes or manual handling to deliver fixed-length C-shaped steel to the feeding station of the coiling processing equipment, and then using primitive methods such as three-roll coiling machines, manual mold forming, cold bending, or hot bending to complete the coiling process. However, this method has many drawbacks: the specifications of the fixed-length steel are inconsistent, and the length varies greatly; manual sorting and feeding are inefficient and cannot meet the needs of automated continuous production; manual operation leads to unstable feeding rhythm, directly affecting the continuity of the coiling process and the consistency of product quality; the labor intensity of employees is high, the product dimensional stability is poor, the number of employees remains high, and labor costs are high; production efficiency is low, product quality consistency is poor, and the pass rate is unsatisfactory.

[0003] Furthermore, in the splicing of structural steel sections, traditional methods mostly employ manual positioning and welding, resulting in low efficiency and inconsistent quality. While some automated welding equipment exists in the existing technology, such as the Chinese patent CN206139954U which discloses an automated angle steel welding machine that uses a gantry frame and welding carriage to weld angle steel, this equipment is a fixed-station welding structure. When splicing structural steel sections, the machine must be stopped for alignment and welding, making it impossible to achieve continuous synchronous operation of feeding and welding simultaneously.

The X-axis displacement component includes an X-axis guide rail bracket fixed to the side of the moving crossbeam, an X-axis guide rail 1602 on the side of the X-axis guide rail bracket, and an X-axis sliding seat 1603 on the X-axis guide rail. An X-axis bearing seat 1604 is installed on the side of the X-axis sliding seat, and a second drive shaft 17 passes through multiple X-axis bearing seats. Multiple Y-axis drive gears 1801 are fixedly connected to the outer periphery of the second drive shaft. A Y-axis fixed slide groove is also provided on the side of the X-axis sliding seat, and a Y-axis sliding guide rail bracket 1802 is provided on the Y-axis fixed slide groove. A Y-axis rack 1803 is fixedly connected to the side of the Y-axis sliding guide rail bracket, and multiple Y-axis drive gears 1801 mesh with corresponding Y-axis racks 1803. A second geared motor 19 is also fixedly connected to the movable crossbeam 14. The output end of the second geared motor is connected to the second transmission shaft 17 via a sprocket transmission mechanism. When the second geared motor 19 starts, it drives the second transmission shaft 17 to rotate via the sprocket transmission, which in turn drives the Y-direction transmission gear 1801 to rotate. The Y-direction transmission gear meshes with the Y-direction rack 1803, driving the Y-direction sliding guide bracket 1802 to move up and down vertically along the Y-direction fixed slide groove.

[0052] The bottom of the Y-axis sliding guide rail bracket 1802 is equipped with a pneumatic gripper 110, which is pneumatically controlled to clamp and release the steel profile. Multiple pneumatic grippers are installed at the bottom of each X-axis sliding seat. These grippers operate synchronously during the feeding cycle, gripping different parts of the same steel profile. The steel profile acts as a rigid connector, linking the X-axis sliding seats 1603 together. When the X-axis feeding cylinder 1601 is activated, the X-axis sliding seat 1603 directly connected to it slides along the X-axis guide rail 1602 under the cylinder's push. The thrust is transmitted through the steel profile to the remaining pneumatic grippers, causing the other X-axis sliding seats to slide synchronously. This results in all gripper assemblies, along with the steel profile as a whole, moving towards the feed end of the auxiliary feeding device.

[0053] Multiple feeding brackets are arranged on the feeding base along the feeding direction of the steel profiles. Each feeding bracket includes a fixed bracket 111 and a movable bracket 112. The feeding base is provided with a bracket slide rail 113 that slides along the movable bracket. The movable bracket 112 can slide along the bracket slide rail in the feeding direction to accommodate steel profiles of different lengths. Multiple pawls 11201, which are rotatable around an axis, are arranged at intervals along the vertical direction on the feeding brackets. The pawls are L-shaped. Each pawl has an upper limit block 11202 above it and a lower limit block 11203 below it. The long side of the pawl abuts against the upper limit block, and the short side of the pawl abuts against the lower limit block. When the long side of the pawl supports the steel section, the end of the short side abuts against the lower limit block, forming a stable support for the steel section; when the steel section is removed by the pneumatic gripper, the next layer of steel section touches the previous layer of pawl during the upward displacement, and the pawl flips upward under the action of force.

[0054] An auxiliary feeding device 114 is provided on one side of the discharge end of the feeding frame. The auxiliary feeding device includes a clamping roller bracket 11401, on the top surface of which are rotatably connected an active clamping roller 11402 and a driven clamping roller 11403. A clamping roller motor 11404 is installed inside the clamping roller bracket, and the roller shaft of the active clamping roller 11402 is drivenly connected to the output end of the clamping roller motor 11404. When the clamping roller motor is started, it drives the active clamping roller to rotate. When the profile is fed between the active and driven clamping rollers, the active clamping roller cooperates with the driven clamping roller to clamp the profile and convey it forward.

[0055] Its working principle is as follows:

[0056] Operators use a remote-controlled crane to hoist bundles of steel sections onto the feeding platform 11, arranging the steel sections in rows on the platform's surface. The Z-axis displacement component 12 drives the moving crossbeam to move horizontally towards the feeding platform, bringing the pneumatic grippers 110 to the designated picking position above the platform. The Y-axis displacement component 18 then drives the pneumatic grippers downwards to the platform's surface, picking up the steel sections one by one. After adjusting the position of the moving bracket 112 on the bracket slide rail 113 according to the steel section length, the pneumatic grippers place each steel section onto the pawls of the feeding bracket, completing the sorting process. During material feeding, the pneumatic gripper picks up the target steel profile from the feeding bracket. After being aligned with the feed end of the auxiliary feeding device by the Z and Y displacement components, the X-axis feeding cylinder 1601 drives the steel profile into the space between the active clamping roller 11402 and the driven clamping roller 11403. The clamping roller motor drives the active clamping roller to rotate, smoothly conveying the steel profile to the subsequent welding and splicing station.

[0063] The rotary welding mechanism 26 includes a rotary seat ring 2612 rotatably mounted on a welding frame 216. The rotary seat ring 2612 is equipped with a rotary motor 2601 that drives its rotation. The rotary motor is connected to the rotary seat ring 2612 via a gear set.

The first movable seat is driven to move along the length direction of the crossbeam 2603 via a first linear drive mechanism. A second movable seat 2607 is slidably mounted on the first movable seat 2604. The second movable seat is driven to move along the length direction of the profile steel 23 via a second linear drive mechanism.

The third lead screw 2610 is threadedly connected to the third lead screw nut, which is mounted on the third movable seat 2611.

[0064] Its working process is as follows:

[0065] The steel section is continuously fed by the upstream auxiliary feeding fixture, guided by the roller assembly at the inlet of the moving trolley, and smoothly transported to the working table of the moving trolley. The moving trolley clamps the steel section through the first and second clamping parts, and is driven by the main drive mechanism to move from the upstream initial station along the conveying track to the downstream station, continuously pushing the steel section to the coiling mechanism. After the front end of the steel section is fed into the coiling mechanism and is stably pulled, both the first and second clamping parts release their clamps on the steel section, and the main drive mechanism drives the moving trolley back to the upstream initial station.

[0066] When the infrared detection optocoupler sensor detects a material breakage signal, the system initiates the welding preparation process: the moving trolley retracts to the upstream initial position, the sub-drive cylinder retracts, and the welding frame moves forward under the tension of the return spring, driving the rotary welding mechanism and the docking positioning component to move forward synchronously. The docking positioning component is raised under the action of the vertical drive cylinder, so that the docking stop is in contact with the end face of the front steel section joint, completing the end face positioning. After positioning, the first clamping part and the auxiliary clamping component clamp the front steel section synchronously. The horizontal drive cylinder and the vertical drive cylinder drive the docking stop to descend and retract to make room. The auxiliary feeding fixture feeds the continuing steel section into the moving trolley until its end face is tightly connected with the end face of the front steel section. The second clamping part clamps the continuing steel section, completing the joint clamping of the two-section steel section. The rotary motor drives the rotating seat to rotate around the steel section axis, driving the welding torch to make a circular motion. At the same time, the first linear drive mechanism, the second linear drive mechanism, and the third linear drive mechanism drive the welding torch to achieve multi-dimensional position adjustment, matching the joint position in real time, and completing the full circumference continuous welding of the joint. Throughout the welding process, the main drive mechanism controls the moving trolley to advance synchronously with the steel section conveyor. After welding is completed, each clamping cylinder releases and resets, the sub-drive cylinder extends and pushes the welding frame backward, and the main drive mechanism drives the moving trolley back to the upstream initial position, repeating the cycle.

A dispensing base is fixedly connected to the piston rod end of the dispensing cylinder. A dispensing roller is rotatably connected to the top surface of the dispensing base.

[0075] Its working process is as follows:

[0076] The steel section first enters the feed end of the coiling worktable. As it passes the coiling clamping device, the first active pressure roller and the first driven pressure roller clamp the steel section, and the second active pressure roller and the second driven pressure roller clamp the steel section. An outer pressure guide roller presses the steel section from the outside, bending it into a coil according to a set curvature. The steel section then passes through a primary coiling specification auxiliary forming device. The positioning sliding seat slides along the length of the positioning roller frame to a scale position corresponding to the target coil diameter via a positioning screw transmission mechanism. The positioning rollers, positioning bearings, and positioning cylinders together guide and limit the movement of the steel section.

[0077] After the steel section exits from the primary coiling auxiliary forming device, it passes through the second concave notch on the Z-axis slide of the automatic coiling fixture and moves towards the first coiling support. When the sensor on the first coiling support detects the steel section passing by, the supporting cylinder lifts upward, and the piston rods of the two limit cylinders move towards each other. The steel section passes between the limit roller and the limit bearing, and then passes above the supporting roller. As the steel section continues to advance, it passes through the second, third, fourth, and fifth coiling supports in sequence. Each support activates in the same process to lift and limit the steel section. When the steel section passes the fifth coiling support, the cascading cylinder lifts upward, and the steel section moves towards the secondary coiling platform guided by the cascading roller. When it passes the secondary coiling trajectory positioning device at the feed and discharge ends of the secondary coiling platform, the piston rod of the trajectory positioning cylinder extends, and the trajectory positioning roller limits and guides the inner and outer sides of the steel section.

[0078] During the continuous feeding of the primary coiled steel section, when the secondary coiled steel section passes through the first concave notch, the control system controls the first clamping cylinder and the first feeding positioning cylinder to move in opposite directions, using the pressure head and positioning claws to clamp the secondary coiled steel section. Simultaneously, the control system controls the second clamping cylinder and the second feeding positioning cylinder to move in opposite directions, clamping the primary coiled steel section, and the feeding of the steel section stops. The cutting motor is started to drive the cutting blade to rotate, and the X-axis lead screw transmission mechanism drives the X-axis slide plate to move forward at a constant speed to cut the steel section. After cutting, the blade retracts.

[0079] After cutting, the Y-axis translation cylinder retracts the Y-axis slide, and the Z-axis translation cylinder extends the Z-axis slide, making the secondary coiled steel clamped at the first concave notch level with the primary coiled steel clamped at the second concave notch. Simultaneously, all limit cylinders retract the limit rollers and limit bearings, the material support cylinder lowers, and the leveling frame translation cylinder moves each leveling frame below the steel section. The leveling cylinder then lifts the remaining steel sections, making them level with the steel sections located at the first and second concave notches. Subsequently, the Y-axis translation cylinder extends the Y-axis slide, bringing the end faces of the two clamped steel sections together. The welding machine translation cylinder is then activated, moving the welding machine to the welding position to weld the butt joint of the steel sections.

[0080] During welding, the coiled steel section continues to advance and coil. After welding is completed, the first clamping cylinder and the first feeding and positioning cylinder retract, as do the second clamping cylinder and the second feeding and positioning cylinder, lifting the finished outer ring away. The Y-axis translation cylinder drives the Y-axis slide plate to retract, and the Z-axis translation cylinder drives the Z-axis slide plate to fall. The leveling frame translation cylinder first moves away from the steel section, then controls the leveling cylinder to fall and reset, starting the next coiling cycle.

[0081] The finished product handling mechanism 4 is located at the discharge end of the automatic coiling mechanism. It includes a gantry-type frame, a sliding trolley at the top of the frame, a handling rack below the trolley, and adjustable pneumatic grippers at the end of the handling rack for gripping finished coils of different sizes. A lifting mechanism is provided between the trolley and the handling rack.

[0082] Its working process is as follows:

[0083] The traveling carriage drives the material handling frame to descend to near the finished circular ring via a lifting mechanism. After the material handling gripper grabs the finished ring, the lifting mechanism drives the material handling frame to rise and return to its original position. The traveling carriage moves horizontally along the frame to deliver the finished ring to the set stacking station. After the material handling frame descends to the set height, the material handling gripper releases, and the finished ring is automatically stacked into a pile. Then the traveling carriage and material handling frame return to their original positions to wait for the next material handling cycle.

[0084] The aforementioned mechanisms utilize PLC programming control technology to achieve fully automated linkage control, continuously producing cable reel outer ring steel from the arrival of fixed-length steel to the stacking of finished coils.
