Description

Technical Field

[0001] This utility model relates to the field of sleeve production and processing technology, and more specifically to a sleeve orientation correction and feeding device. Background Technology

[0002] In the manufacturing process of sleeve-type workpieces, after the sleeve is die-cast, it usually requires a series of subsequent processing steps. These include refining the hole patterns at both ends, marking and engraving on the outer wall of the sleeve, or drilling positioning holes on the side of the sleeve. These subsequent processing steps have strict requirements on the orientation of the sleeve when it is fed into the processing station. Only when the sleeve enters the processing station in a preset specific orientation can the processing equipment accurately align with the part to be processed, ensuring processing accuracy and product quality, while also ensuring a smooth and efficient processing flow. If the sleeve is positioned incorrectly, it will not only prevent the processing steps from proceeding normally, but may also cause damage to the processing tools, scrap of the workpiece, and other problems, significantly increasing the defect rate and production costs.

[0003] Currently, the industry still mainly relies on traditional methods for orientation correction and feeding operations of sleeves in subsequent processing: on the one hand, most small and medium-sized production scenarios rely on manual operation, where operators visually distinguish the differences in hole shape or appearance characteristics at both ends of the sleeve, manually adjust the orientation of the sleeve, and then transfer it to the processing station. This method not only requires a significant investment of manpower, but manual judgment is also susceptible to factors such as fatigue, visual errors, and operator skill levels, resulting in low accuracy in sleeve orientation correction and frequent issues of incorrect or missing installations. Furthermore, the slow pace of manual feeding makes it difficult to adapt to the high-efficiency requirements of automated processing equipment, severely restricting overall production efficiency. On the other hand, some production scenarios using semi-automated equipment, while achieving automatic sleeve conveying and gripping, lack reliable orientation detection and automatic correction mechanisms. Either they rely solely on mechanical stops for rough positioning of the sleeve, failing to identify and adjust its orientation, or they require additional complex optical detection systems. This significantly increases equipment manufacturing costs, and optical detection is easily affected by factors such as sleeve surface contamination, ambient light, and workpiece material reflection, leading to poor detection stability and still requiring manual verification. This fails to truly achieve full automation of the "conveyance-correction-feeding" process, making it difficult to meet the high-precision, high-stability requirements of subsequent sleeve processing. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a sleeve orientation correction and feeding device that can automatically complete sleeve orientation detection, correction and precise feeding, with stable operating efficiency and a high degree of automation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sleeve orientation correction feeding device, characterized in that it includes a frame, on which a horizontally arranged double circular belt conveyor is installed, and at the end of the double circular belt conveyor is a limiting seat for positioning the sleeve; a column is provided on the outside of the limiting seat, and a horizontal feeding cylinder is mounted on the top of the column; a lifting cylinder is connected to the cylinder shaft end of the horizontal feeding cylinder, and a rotating cylinder is connected to the cylinder shaft end of the lifting cylinder; a finger cylinder for gripping the sleeve is mounted on the rotating shaft end of the rotating cylinder; a blocking cylinder is correspondingly arranged on the side of the finger cylinder, and a pin is axially connected to the cylinder shaft end of the blocking cylinder; the free end of the pin is adapted to the hole shape of one end of the sleeve but cannot be adapted to the hole shape of the other end of the sleeve; a sensor for sensing the stroke state of its cylinder shaft is mounted on the blocking cylinder.

[0006] This invention offers high calibration accuracy: through a customized design that matches the hole patterns at both ends of the sleeve to the ejector pin, combined with real-time detection of the blocking cylinder's stroke by sensors, it can automatically identify whether the sleeve's orientation is correct. (The blocking cylinder drives the ejector pin to extend horizontally, so that when the lifting cylinder, along with the finger cylinder and the sleeve being grasped, rises to a preset height, the ejector pin can either enter the sleeve's matching hole pattern or be blocked by an incompatible hole pattern. Furthermore, the sensor controls the rotation of the rotary cylinder based on the sensed stroke state to achieve sleeve discharge.) This completely replaces manual judgment, effectively avoiding the misjudgments and omissions that easily occur during manual visual inspection, ensuring strong consistency after sleeve orientation calibration.

[0007] This invention features a high degree of automation: the device integrates a double circular belt conveyor, a flat conveying cylinder, a lifting cylinder, a rotating cylinder, and a finger cylinder, which can autonomously complete the entire process of conveying, positioning, gripping, correcting, and discharging the sleeve without the need for manual intervention in intermediate steps, thus significantly reducing labor costs.

[0008] This invention offers stable operating efficiency: the cylinders work in concert, with rapid response and seamless process integration, avoiding rhythmic differences in manual operation; at the same time, precise sensor-based control can quickly trigger the rotary cylinder to adjust its position (requiring only a 180° rotation), eliminating the need for repeated trial and error and ensuring stable and efficient sleeve feeding.

[0009] Preferably, the double circular belt conveyor includes two drive pulleys arranged at intervals along the conveying direction. Each drive pulley has a pair of coaxial and parallel circular slots on its outer peripheral wall. The circular slots on the two drive pulleys correspond one-to-one. A drive circular belt is fitted into each pair of corresponding circular slots. The two drive circular belts are arranged in parallel and at intervals, forming a conveying channel for carrying the sleeve. A speed-regulating motor is connected to the end of the axle of one of the drive pulleys.

[0010] This invention uses the circular grooves on the transmission pulley to precisely position the transmission belt, ensuring the parallelism and spacing stability of the two belts and preventing misalignment during sleeve conveying. A single motor drive enables the two belts to rotate synchronously, while simplifying the transmission structure, reducing equipment failure rate, and further improving conveying accuracy and reliability.

[0011] Preferably, a storage frame is provided below the dual circular belt conveyor, and a stepped lifting feeder is provided between the storage frame and the dual circular belt conveyor; the stepped lifting feeder includes a base shell, on which a lifting plate and a fixed plate are arranged in a stepped, staggered, alternating pattern from bottom to top. The lifting plate is slidably mounted on the base shell, and the fixed plate is fixedly mounted on the base shell, and the lifting plate can slide relative to the fixed plate in a staggered manner; all the lifting plates are connected to a lifting plate that synchronously drives their reciprocating motion, and the lifting plate is eccentrically connected to a turntable through a connecting rod, and the turntable is sleeved on the motor shaft of a drive motor.

[0012] This utility model storage frame can realize batch storage of sleeves. The stepped lifting feeder can smoothly and steadily transport the sleeves in the storage frame to the double circular belt conveyor by the staggered sliding cooperation of the lifting plate and the fixed plate, avoiding the sleeves from accumulating and jamming. At the same time, the eccentric structure driven by a single drive motor simplifies the transmission, improves the stability of the feeding rhythm, and realizes fully automatic feeding of the device.

[0013] Preferably, a side guard plate is provided on the side of the double circular belt conveyor, and a horizontal pass-through baffle is installed on the side guard plate. A preset distance is formed between the horizontal pass-through baffle and the drive circular belt of the double circular belt conveyor. This distance only allows the sleeve in a lying position to pass through and can block the sleeve in a standing position. A return guide hopper is provided directly below the horizontal pass-through baffle, and the lower end of the return guide hopper is connected to the storage frame.

[0014] This invention, through the spacing design between the horizontal pass and the transmission belt, can automatically select horizontal sleeves that meet the orientation requirements of subsequent processing, avoiding standing sleeves from entering subsequent processes and causing jamming or correction errors; at the same time, the blocked standing sleeves flow back to the storage frame through the return guide hopper, realizing sleeve circulation feeding, reducing material waste, and further improving the stability and continuity of the device's feeding.

[0015] Preferably, a cantilever beam is provided on the inner wall of the return material guide hopper, and a baffle plate is suspended on the cantilever beam. The baffle plate swings freely through the cantilever beam, and the swing direction of the baffle plate is adapted to the falling direction of the sleeve in the return material guide hopper.

[0016] The freely swinging baffle of this utility model can buffer the impact force when the standing sleeve falls, and avoid damage or deformation of the sleeve due to impact with the inner wall of the return guide hopper; at the same time, it can slow down the falling speed of the sleeve, prevent multiple sleeves from accumulating and blocking the return guide hopper, and ensure smooth return channel.

[0017] Preferably, a downwardly inclined discharge plate is provided directly below the finger cylinder. The upper surface of the discharge plate is provided with a pair of parallel and spaced slide rails along its inclined direction, and a discharge channel adapted to the length direction of the sleeve is formed between the two slide rails.

[0018] The channel of this utility model is adapted to the length direction of the sleeve, which can force the corrected sleeve to slide down one by one along the preset length direction, avoiding lateral jamming or misalignment; with the gravity assistance of the inclined discharge plate, it ensures that the sleeve is accurately conveyed to the next station in a regular arrangement, which fully matches the requirements of subsequent processing for the sleeve orientation.

[0019] Preferably, of the two slide rails, one is a fixed slide rail, which is directly fixed to the discharge plate, and the other is a movable slide rail; a connecting plate is fixedly connected to the fixed slide rail, and an oblong hole extending along the distance between the two slide rails is opened on the connecting plate. A locking screw passes through the oblong hole, and the end of the locking screw is fixedly connected to the movable slide rail to lock the distance between the two slide rails.

[0020] This utility model allows for flexible adjustment of the distance between the movable and fixed slide rails through the combination of the oblong hole and the locking screw, enabling the discharge channel to accommodate sleeves of different diameters and improving the device's versatility for different types of sleeves. At the same time, the locking structure ensures stability and prevents loosening after the distance is adjusted, guaranteeing the trajectory accuracy of the sleeve during conveying.

[0021] Beneficial effects: (1) Full-process automation and high-precision correction: Through the exclusive matching of the ejector pin and the sleeve hole type, sensor stroke detection and multi-cylinder coordinated action, the sleeve “feeding-screening-correction-discharge” full-process automation is realized, which not only replaces manual judgment to avoid misjudgment and omission, but also ensures the accuracy of orientation correction and effectively reduces the defect rate of subsequent processing.

[0022] (2) Stable material supply and high material utilization rate: Relying on the step-type lifting feeder to transport the sleeve piece by piece, and with the horizontal pass to screen the lying workpiece, the standing sleeve is returned to the storage box through the return guide bucket. This not only avoids the accumulation and jamming of the supply, but also realizes the recycling of materials, reduces waste and ensures the continuity of the supply.

[0023] (3) Strong adaptability and practicality: The adjustable tension wheel of the double circular belt conveyor can ensure the conveying accuracy. The movable slide rail of the discharge plate can adjust the spacing through the waist-shaped hole to adapt to different diameter sleeves. There is no need to configure separate equipment for different specifications of sleeves, which greatly improves the versatility and cost-effectiveness of the device. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0027] Example: Figure 1 As shown, a sleeve orientation correction feeding device includes a frame 1, on which a horizontally arranged double circular belt conveyor 2 is mounted, and at the end of the double circular belt conveyor 2 is a limiting seat 3 for positioning the sleeve.

[0028] The double circular belt conveyor 2 includes two drive pulleys arranged at intervals along the conveying direction. Each drive pulley has a pair of coaxial and parallel circular slots on its outer peripheral wall. The circular slots on the two drive pulleys correspond one-to-one. A drive circular belt is fitted into each pair of corresponding circular slots. The two drive circular belts are arranged in parallel and at intervals, forming a conveying channel for carrying the sleeve. A speed regulating motor 12 is connected to the end of the axle of one of the drive pulleys.

[0029] A column 4 is provided on the outer side of the limiting seat 3. A horizontal feeding cylinder 5 is installed at the top of the column 4. A lifting cylinder 6 is connected to the cylinder shaft end of the horizontal feeding cylinder 5. A rotary cylinder 7 is connected to the cylinder shaft end of the lifting cylinder 6. A finger cylinder 8 for gripping the sleeve is installed at the rotating shaft end of the rotary cylinder 7.

[0030] A blocking cylinder 9 is provided on the side of the finger cylinder 8. A pin 10 is axially connected to the end of the cylinder shaft of the blocking cylinder 9. The free end of the pin 10 is adapted to the hole shape of one end of the sleeve but cannot be adapted to the hole shape of the other end of the sleeve. A sensor 11 for sensing the stroke state of its cylinder shaft is mounted on the blocking cylinder 9.

[0031] A storage box 13 is provided below the double circular belt conveyor 2, and a stepped lifting feeder 14 is provided between the storage box 13 and the double circular belt conveyor 2.

[0032] like Figure 2 As shown, the stepped lifting feeder 14 includes a base shell 15. The base shell 15 is provided with a lifting plate 16 and a fixed plate 17 arranged in a stepped, staggered, alternating pattern from bottom to top. The lifting plate 16 is slidably mounted on the base shell 15, and the fixed plate 17 is fixedly mounted on the base shell 15. The lifting plate 16 can slide relative to the fixed plate 17 in a staggered manner. All the lifting plates 16 are connected to a lifting plate 18 that synchronously drives them to reciprocate. The lifting plate 18 is eccentrically connected to a turntable 20 through a connecting rod 19. The turntable 20 is sleeved on the motor shaft of a drive motor 21.

[0033] A side guard plate 22 is provided on the side of the double circular belt conveyor 2. A horizontal pass-through baffle 23 is installed on the side guard plate 22. A preset gap is formed between the horizontal pass-through baffle 23 and the drive circular belt of the double circular belt conveyor 2. This gap only allows the sleeve in the lying position to pass through and can block the sleeve in the standing position. A return guide hopper 24 is provided directly below the horizontal pass-through baffle 23. The lower end of the return guide hopper 24 is connected to the storage frame 13.

[0034] A cantilever beam is provided on the inner wall of the return guide hopper 24. A baffle plate 25 is suspended on the cantilever beam. The baffle plate 25 swings freely through the cantilever beam, and the swing direction of the baffle plate is matched with the falling direction of the sleeve in the return guide hopper.

[0035] like Figure 3 As shown, a downwardly inclined discharge plate 26 is provided directly below the finger cylinder 8. The upper surface of the discharge plate 26 is provided with a pair of parallel and spaced slide rails along its inclined direction, and a discharge channel adapted to the length direction of the sleeve is formed between the two slide rails.

[0036] Of the two slide rails, one is a fixed slide rail 27, which is directly fixed to the discharge plate 26, and the other is a movable slide rail 28. A connecting plate 29 is fixedly connected to the fixed slide rail 27. The connecting plate 29 has an oblong hole 30 extending along the distance between the two slide rails. A locking screw 31 passes through the oblong hole 30. The end of the locking screw 31 is fixedly connected to the movable slide rail 28 to lock the distance between the two slide rails.

[0037] Working process: (1) Batch feeding and screening: The sleeves in the storage box are conveyed one by one to the double circular belt conveyor by the stepped lifting feeder (the lifting plate and the fixed plate are misaligned and slide); when the double circular belt conveyor is running, the horizontal pass of the side guard plate screens out the lying sleeves through the gap with the transmission circular belt. The standing sleeves are blocked and fall into the return guide hopper, and after being buffered by the baffle plate, they flow back to the storage box.

[0038] (2) Orientation correction: The double circular belt conveyor transports the lying sleeve to the end limit seat for positioning; the flat conveying cylinder pushes the lifting cylinder, rotating cylinder and finger cylinder to move above the sleeve, the lifting cylinder descends so that the finger cylinder grabs the sleeve and rises to the preset height; the blocking cylinder drives the ejector pin to extend horizontally. If the ejector pin extends into the sleeve's matching hole (the sensor detects that the stroke is in place), the sleeve orientation is correct; if the ejector pin is blocked (the sensor detects that the stroke is not in place), the rotating cylinder drives the sleeve to rotate 180° to complete the correction.

[0039] (3) Precise discharge: After the orientation correction is completed, the flat conveying cylinder moves the sleeve to the top of the discharge plate and the finger cylinder is released; the sleeve slides down the downward-sloping discharge plate and is transported to the next processing station one by one through the channel formed by the fixed slide rail and the movable slide rail (the spacing is appropriate for the sleeve specifications) in a regular length direction.
