Description

Technical Field

[0001] This utility model belongs to the technical field of automated spool production line, specifically relating to a vertical warehouse feeding conversion table used in an automated spool production line. Background Technology

[0002] In an automated wire reel production line, the vertical storage unit (LSU) serves as the core storage unit, which needs to transport the wire reels to different processing units according to production requirements. However, the conveyor tracks of each processing unit have different directions, such as the vertical storage unit's outbound conveyor being longitudinal and the forming unit's inbound conveyor being transverse. There are also differences in height, such as the vertical storage unit's roller conveyor being 1200mm high and the surface treatment unit's inbound conveyor being 800mm high. Intermediate conversion equipment is needed to achieve the connection.

[0003] Traditional connection methods often use manual assisted transfer or simple fixed brackets. Traditional connection methods have certain defects. Simple fixed guide structures can only adapt to single-direction conversion. When the production line needs to change direction, it is inconvenient to adjust in the vertical direction. They have the disadvantages of low efficiency, poor flexibility and insufficient positioning accuracy, which can easily lead to positioning failure in subsequent processing steps, thereby affecting product quality. Therefore, a vertical warehouse feeding changeover table for automated reel production lines is needed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical warehouse feeding transfer table for an automated reel production line, comprising: The base support unit is used for the foundation support of the equipment; The base support unit includes a fixed base, an anti-tipping counterweight, and a horizontal calibration component. The height adjustment unit, installed above the base support unit, is used to adjust the height of the spool within a certain range. The height adjustment unit includes a movable seat, a lifting platform, and a height detection module; The direction conversion unit, installed on top of the height adjustment unit, is used to drive the reel to achieve automatic conversion of the conveying direction from 0 to 90°; The direction conversion unit includes a rotary table, a rotary drive assembly, and an angle limit module; The cable reel positioning unit is installed on the rotary table of the direction conversion unit and is used for precise positioning of the cable reel after it enters the conversion table. The reel positioning unit includes a side push plate, a support platform, and a positioning detection component.

[0006] As a preferred embodiment, the fixed base includes two symmetrically arranged rectangular frame structures, with a crossbeam and a longitudinal beam welded between the two rectangular frames.

[0007] As a preferred embodiment, a hydraulic rod is provided at the center of the movable seat, the telescopic end of the hydraulic rod is fixedly connected to the lifting platform, and a guide column is fixedly connected to the lower surface of the lifting platform, passing through the movable seat and sliding vertically connected to the movable seat.

[0008] As a preferred embodiment, the rotary drive assembly includes a gear and a gear ring, the gear ring being fixedly connected to the lower surface of the rotary table, the movable seat being a box structure, with a servo motor fixedly mounted at the center, and the output shaft of the servo motor passing through the lifting table and being fixedly connected to the gear.

[0009] As a preferred embodiment, the bottom of the rotary table is equipped with a ring track, the lifting platform is provided with pulleys, and the surface of the rotary table is covered with a thick polyurethane anti-slip mat.

[0010] As a preferred embodiment, the side push plate and the support platform are symmetrically arranged on both sides of the reel. The support platform is fixed on the rotating platform. Two symmetrically arranged guide rods are fixedly connected to the surface of the side push plate. The two guide rods pass through the support platform and are horizontally limited and slidably connected to the support platform.

[0011] As a preferred embodiment, a guide rail is fixedly installed on the upper surface of the fixed base, and sliding seats adapted to the guide rail are fixedly connected to both sides of the movable seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting a height adjustment unit, can meet the needs of different heights; at the same time, it sets a direction conversion unit to realize 0-90° direction conversion. Compared with the traditional simple structure, which can only convert one direction and is inconvenient for vertical adjustment, it can flexibly match the direction and height requirements of different processing units, replace manual transportation, and the direction and height adjustment does not require structural replacement. It can quickly respond to changes in production line requirements and greatly improve efficiency and flexibility.

[0013] This invention addresses the core problem of insufficient positioning accuracy in traditional methods, which leads to subsequent processing failures and affects product quality. By setting up a wire reel positioning unit, an electric push rod drives the side push plate to slide horizontally along the guide rod, thereby achieving radial positioning offset of the wire reel. This avoids positioning failures in subsequent processing and ensures product quality. Attached Figure Description

The height adjustment unit includes a movable seat 3, a lifting platform 4, and a height detection module; The direction conversion unit, installed on top of the height adjustment unit, is used to drive the reel to achieve automatic conversion of the conveying direction from 0 to 90°; The direction conversion unit includes a rotary table 5, a rotation drive assembly, and an angle limit module; The wire reel positioning unit is installed on the rotary table 5 of the direction conversion unit. It is used to accurately position the wire reel after it enters the conversion table, ensuring that the coaxiality error between the center axis of the wire reel and the axis of the production line track is ≤0.5mm. The coil positioning unit, the side push plate 6, the bearing platform 7, and the positioning detection component.

[0019] The fixed base 1 includes two symmetrically arranged rectangular frame structures, with crossbeams and longitudinal beams welded between the two rectangular frames to improve the stability and load-bearing capacity of the device body. It can flexibly match the orientation and height requirements of different processing units, thereby ensuring the efficiency and flexibility of feeding conversion.

[0020] The fixed base 1 is made of Q355B steel plate welded into a rectangular frame structure with a frame cross-section of 2000mm×1500mm. The bottom is fixed to the ground by 8 sets of M20×100mm expansion bolts. The frame crossbeams and longitudinal beams are all made of H-beams of model H200×200×8×12 with a load-bearing capacity of ≥5000kg, which meets the 500kg conversion requirement of heavy-duty cable reels.

[0021] Anti-tipping counterweights are installed at the four corners of the bottom of the fixed base 1. They are made of cast iron with a density of 7.2g / cm³ and a single weight of 500kg. They are rigidly connected to the base by bolts to lower the center of gravity of the equipment and prevent tipping when adjusting the height or changing the direction. The horizontal calibration component includes a level with an accuracy of 0.02 mm / m installed around the top of the base, and adjustable feet with an adjustment range of 0-50 mm. During equipment installation, the base level is adjusted using the feet to ensure a horizontal error of ≤0.1 mm / m, preventing the coil from slipping due to base tilt during coil switching.

[0022] A hydraulic rod 11 is provided at the center of the movable seat 3. The telescopic end of the hydraulic rod 11 is fixedly connected to the lifting platform 4. A guide column 10 that passes through the movable seat 3 and is vertically slidably connected to the lower surface of the lifting platform 4 is fixedly connected to the lower surface of the lifting platform 4. Furthermore, hydraulic rod 11 is replaced with a scissor lift mechanism: adopting a double scissor structure, the scissor arms are made of 45# steel with surface quenching treatment, hardness HRC45-50, and cross-sectional dimensions of 80mm×40mm×5mm. The scissor arms are connected by high-strength pins with a diameter of 20mm. Self-lubricating bearings are installed at both ends of the pins to reduce lifting friction. Guide sliders are set at the top and bottom of the lifting mechanism to ensure no lateral deviation during lifting. A servo motor with a power of 4kW and a speed of 1500rpm drives a ball screw transmission. The ball screw has a diameter of 60mm and a lead of 10mm. It is equipped with a planetary reducer with a reduction ratio of 1:30. Lifting is achieved by pushing the scissor arms to open and close through the ball screw. The lifting speed is adjustable from 5-10mm / s, and the height adjustment accuracy is ±0.5mm to meet the track height adaptation requirements of different processing units.

[0023] The height detection module uses a laser displacement sensor installed on the top of the lifting mechanism. The measurement range is 0-2000mm with an accuracy of ±0.05mm. It collects the current height data of the equipment in real time and compares it with the target height, such as the height of the forming unit track of 1000mm, to form a closed-loop control and ensure that the height adjustment is accurate.

[0024] The rotary drive assembly includes a gear 13 and a gear ring 14. The gear ring 14 is fixedly connected to the lower surface of the rotary table 5. The movable seat 3 is a box structure with a servo motor fixedly installed in the center. The output shaft of the servo motor passes through the lifting table 4 and is fixedly connected to the gear 13. The system employs a gear 13 transmission method. The external gear ring 14 has a module of 3 and 180 teeth. It is driven by a servo motor with a power of 2.2kW and a speed of 3000rpm. The gear 13 has a module of 3 and 20 teeth. The rotation table 5 is rotated through the meshing of the gear 13. The rotation speed is adjustable from 1 to 5° / s, and the angle control accuracy is ±0.1°. The angle can be set to any angle according to production needs (such as 30°, 90°). The rotary table 5 is made of circular steel plate with a diameter of 1800mm and a thickness of 20mm. The material is Q355B, and the surface is covered with a 5mm thick polyurethane anti-slip pad to prevent the coil from sliding when changing direction.

[0025] The bottom of the rotary table 5 is equipped with a circular track 8, and the lifting platform 4 is equipped with pulleys 9. The rotary table 5 adopts a circular steel plate structure with a diameter of 1800mm and a thickness of 20mm. The material is Q355B, and the surface is covered with a 5mm thick polyurethane anti-slip pad to prevent the coil from sliding when changing direction. There are 8 pulleys 9, which are evenly distributed to ensure the stability of rotation. The angle limit module uses a photoelectric encoder with a resolution of 10,000 lines installed on the outside of the rotating platform to collect rotation angle data in real time; at the same time, a mechanical limit block is set on the top of the fixed base 1 to correspond to the 0° and 90° positions. The block is made of polyurethane material with a thickness of 50mm to avoid mechanical collisions caused by excessive rotation, thus providing double protection for angle accuracy. The side push plate 6 and the support platform 7 are symmetrically arranged on both sides of the coil. The support platform 7 is fixed on the rotary table 5. Two symmetrically arranged guide rods 12 are fixedly connected to the surface of the side push plate 6. The two guide rods 12 pass through the support platform 7 and are horizontally limited and slidably connected to the support platform 7. Two symmetrically arranged electric push rods are installed on the rotary table 5. The bearing platform 7 adopts an arc structure with the curvature matching the outer circle of the wire spool. A 3mm thick silicone buffer pad is pasted on the inner side of the side push plate 6 to avoid damaging the surface of the wire spool. The electric push rod drives the wire spool to move closer to the side push plate 6 to achieve radial positioning. After positioning, the radial offset of the wire spool is ≤0.1mm. A guide rail 2 is fixedly installed on the upper surface of the fixed base 1. Sliding seats adapted to the guide rail 2 are fixedly connected to both sides of the movable seat 3. A lead screw and a servo motor for driving the movable seat 3 to move horizontally are provided on one side of the bottom of the two fixed bases 1. The lead screw passes through the bottom connecting seat of the movable seat 3 and is screwed to it. Under the action of the servo motor, the movable seat 3 is driven to move to achieve precise delivery of the coil on the rotary table 5. Furthermore, it also includes a conveyor connection unit, installed on a rotating platform, for conveying the wire reel in the converter and connecting it with the vertical warehouse and production line, including a segmented roller conveyor, docking guide components and conveyor detection module; Segmented roller conveyor: It consists of an infeed roller conveyor connecting to the vertical storage unit, a transfer roller conveyor located at the center of the rotating platform, and an outlet roller conveyor connecting to the production line. The axes of the three roller conveyors can be synchronously changed with the rotating platform. The rollers are made of seamless steel pipes with an outer diameter of 80mm and a wall thickness of 5mm, with a chrome-plated surface. The rollers are spaced 200-300mm apart to ensure that the reel is supported by at least 3 rollers. Each roller conveyor segment is equipped with an independent geared motor with a power of 0.75kW and a speed of 1400rpm, driven by chain transmission, with a conveying speed of 0.8-1.2m / s, which can be synchronized with the conveying speed of the vertical storage unit and the production line. Docking guide assembly: Guide horn openings are set at the connection ends of the feed roller conveyor and vertical storage, and the connection ends of the discharge roller conveyor and production line. The opening width gradually changes from 2000mm to 20mm in wire reel diameter. The guide plate is made of polyethylene material with a thickness of 10mm to reduce friction when wire reels are docked. Meanwhile, a photoelectric sensor is installed at the connection end to detect the distance of 0-500mm, detect whether the coil has reached the docking position, and then trigger the conveying action; The conveying detection module is equipped with diffuse reflection photoelectric switches on both sides of the transfer roller conveyor to detect the distance from 0-1000mm. It monitors the position of the wire reel in the conversion table in real time. When the wire reel reaches the center of the transfer roller conveyor, the positioning unit is triggered to start. After the wire reel completes the direction and height conversion, the discharge roller conveyor is triggered to transport the wire reel to the production line.

[0026] Working principle and usage process of this utility model: When the wire spool is conveyed to the rotary table 5, the electric push rod of the wire spool positioning unit is activated, driving the two side push plates 6 to move horizontally along the guide rod 12 and move radially toward the wire spool until the side push plates 6 are in contact with the wire spool. After the positioning detection component confirms that the radial offset of the wire spool is ≤0.1mm, the electric push rod stops, and the positioning is completed. The control system receives the track height signal of the target processing unit, such as 800mm for the surface treatment unit, and drives the scissor lift mechanism with a servo motor. The laser displacement sensor collects the current height in real time and compares it with the target height to form a closed-loop adjustment until the height error is within ±0.5mm, at which point the lifting mechanism stops.

[0027] The control system starts the servo motor of the direction conversion unit according to the track direction of the target processing unit, such as the horizontal direction. The gear 13 meshes with the gear ring 14 to drive the rotary table to rotate. The photoelectric encoder provides real-time feedback of the angle, and the speed is controlled at 1-5° / s. When the rotation reaches the target angle (such as 90°), the servo motor stops after double confirmation by the mechanical limit block and the encoder.

[0028] After the discharge docking conversion table and the production line height and direction meet the standards, the discharge roller conveyor is started and the conveying speed is adjusted to be synchronized with the production line at 0.8-1.2m / s; The wire reel is guided through the flared end of the discharge end to connect with the production line track. Once the photoelectric sensor at the discharge end detects that the wire reel has fully entered the production line, the discharge roller conveyor stops.

[0029] The equipment is reset to await material. The lead screw drives the moving seat 3 to return to the initial position along the guide rail 2 on the fixed base 1. The lifting mechanism drives the lifting platform 4 to reset to the initial height, and the rotary table 5 rotates back to the initial angle of 0°. Each unit returns to standby mode and waits for the next wire reel feeding signal.
