Description

Technical Field

[0001] This utility model relates to the field of sorting technology, and in particular to a high-speed needle roller sorting machine pusher feeding device. Background Technology

[0002] In the production and sorting process of needle rollers, the efficiency and accuracy of the feeding process directly affect the efficiency and quality of the entire sorting process. As the core component of high-precision bearings, needle rollers have extremely high requirements for dimensional consistency and surface quality. Therefore, the feeding device must ensure that the needle rollers enter the sorting station in a stable, orderly and undamaged manner.

[0003] A typical pusher feeding device includes a vibratory feeder system, a linear feeding track, a sorting / pin blocking mechanism, and a pusher mechanism. Most existing feeding devices rely on vibratory feeders for orientation and sorting. However, the high aspect ratio (slender cylindrical shape) of the rollers makes them prone to overlapping, crossing, or incorrect posture during vibratory conveying, requiring multiple adjustments. This leads to delayed feeding cycle and poor feeding. In addition, fluctuations in cylinder thrust (when the air pressure is unstable) can cause the pusher to fail to reach its position or overshoot, resulting in low sorting efficiency and failing to meet the needs of high-speed production.

[0004] Therefore, given that the existing feeding devices are prone to overlapping, crossing, or incorrect posture during vibration conveying, requiring multiple adjustments, resulting in delayed feeding cycle and poor feeding, and that fluctuations in cylinder thrust can cause the pusher needles to not be in place or overshoot, a high-speed needle roller separator pusher feeding device can be designed to improve the feeding speed and stability, reduce needle jamming, and lower maintenance costs and failure rate. Utility Model Content

[0005] In order to overcome the problems that existing feeding devices are prone to overlapping, crossing or incorrect posture during vibratory conveying, requiring multiple adjustments, resulting in delayed feeding cycle and poor feeding, and in addition, fluctuations in cylinder thrust can cause problems such as the pusher not being in place or overshooting.

[0006] The technical solution of this utility model is as follows: a high-speed needle roller sorting machine needle feeding device, including a feeding worktable, a needle storage bin, a guide frame, a needle pusher, and a needle sorting turntable. The needle sorting turntable is installed on one side of the pushing direction of the needle pusher. It also includes a needle pushing mechanism. The feeding worktable is equipped with a needle pushing mechanism for controlling the reciprocating motion of the needle pusher in the horizontal direction. The upper end of the needle sorting turntable has annularly distributed needle sorting grooves. Limiting blocks are installed on the inner walls of both sides of the needle sorting grooves. The needle pushing mechanism includes a linear track, a motor mounting base, and a mounting frame. A drive motor is installed on the upper end of the motor mounting base. Sprockets are installed on the outer side of the output shaft of the drive motor and inside the mounting frame. A transmission chain is meshed on the outer side of each sprocket. A slider is slidably connected to the outer side of the linear track. A connecting block is fixedly connected between the slider and the transmission chain. A shock-absorbing pad is fixedly connected to the lower end of the motor mounting base.

[0007] Preferably, the needle rollers are pre-stored in the needle storage chamber and fall naturally to the bottom outlet by gravity. After the needle rollers slide out from the bottom of the needle storage chamber, they enter the guide frame. The drive motor is powered on and rotates, causing the sprocket on its output shaft to rotate. Through the meshing transmission chain, the sprocket on the other side rotates synchronously, causing the transmission chain to circulate in a straight line. The connecting block is fixed on the transmission chain and drives the slider to slide along the straight track. The slider is connected to the pusher rod, causing the pusher rod to reciprocate in a straight line in the horizontal direction. When the pusher rod pushes forward, it pushes the needle rollers out of the guide frame and into the needle slot of the needle distribution turntable. The limit block ensures that the needle rollers fall accurately into the needle slot, preventing deviation or jamming. The needle distribution turntable rotates, causing each needle slot to move to the next station in sequence. The vibration generated by the pusher mechanism during operation is absorbed by the shock-absorbing pad, ensuring smooth operation of the equipment and reducing noise and wear. The pusher rod returns to its original position, waiting for the next batch of needle rollers to enter the guide frame. The above steps are repeated to achieve continuous automated feeding.

[0008] Preferably, the needle storage chamber has a needle outlet at the bottom, and an adjustable needle outlet gate is provided at the needle outlet. The guide frame is connected to the needle outlet at the bottom of the needle storage chamber.

[0009] Preferably, the width of the needle groove matches the diameter of the needle roller, and the limiting block is made of rubber.

[0010] Preferably, the upper end of the feeding worktable is equipped with a servo motor with a concentric structure to the minute dial, the output shaft of the servo motor is fixedly connected to the lower end of the minute dial, the lower end of the minute dial is fixedly connected with a ring of equally spaced support slides, and the upper end of the feeding worktable is provided with an annular groove that matches the support slides.

[0011] Preferably, the upper end of the feeding workbench is fixedly connected to guide support frames that are symmetrically distributed about the front and rear of the pusher rod, and a guide sleeve fitted onto the outside of the pusher rod is fixedly connected between the two guide support frames.

[0012] Preferably, the cover plate of the storage chamber is connected to the needle storage chamber by a hinge. The needle storage chamber is made of stainless steel and has a viewing window made of transparent plexiglass. A first support frame is fixedly connected to the feeding workbench on the outside of the needle storage chamber.

[0013] As a preferred option, the guide frame adopts an inclined design with a lower front and a higher rear, and anti-collision pads are installed on the inner wall of the front side of the guide frame. Limiting plates are fixedly connected to both ends of the guide frame, and a second support frame is fixedly installed at the lower end of the guide frame and fixedly connected to the loading worktable. The distance between the limiting plates matches the length of the needle roller.

[0014] The beneficial effects of this utility model are as follows: An adjustable needle gate is set at the bottom of the needle storage chamber to precisely control the falling speed of the needle rollers, avoiding accumulation or uneven feeding. The guide frame adopts a front-low and rear-high inclined design, which, together with the limit plate, ensures that the needle rollers are arranged in an orderly single row, reducing needle jamming or posture errors. The needle pushing mechanism uses a combination of chain drive and linear track, which provides more stable thrust compared to cylinder drive, avoiding needle incomplete or overshooting. The needle slot on the needle dividing turntable ensures that the needle rollers fall accurately, while the rubber limit block can prevent the needle rollers from being damaged by collision. By optimizing the coordinated design of the needle storage chamber, guide frame, needle pushing mechanism and needle dividing turntable, the problems of needle overlap, crossing, posture errors and cylinder thrust fluctuations in traditional vibratory conveying are effectively solved, significantly improving the feeding speed and stability.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4This utility model provides an embodiment: a high-speed needle roller sorting machine needle feeding device, including a feeding worktable 1, a needle storage bin 2 disposed on the upper end of the feeding worktable 1, a guide frame 3, a needle pusher 4, and a needle sorting turntable 5. The needle sorting turntable 5 is installed on the side of the pusher 4 in the pushing direction. It also includes a needle pushing mechanism. The upper end of the feeding worktable 1 is equipped with a needle pushing mechanism for controlling the reciprocating motion of the pusher 4 in the horizontal direction. The upper end of the needle sorting turntable 5 has annularly distributed needle sorting grooves 51. The needle sorting grooves 51 are located on both sides. A limit block 52 is installed on the inner wall. The pusher mechanism includes a linear track 61, a motor mounting base 62, and a mounting frame 63. A drive motor 64 is installed on the upper end of the motor mounting base 62. A sprocket 65 is installed on the outer side of the output shaft of the drive motor 64 and inside the mounting frame 63. A transmission chain 66 is meshed on the outer side of each of the two sprockets 65. A slider 67 is slidably connected to the outer side of the linear track 61. A connecting block 68 is fixedly connected between the slider 67 and the transmission chain 66. A shock-absorbing pad 69 is fixedly connected to the lower end of the motor mounting base 62.

[0022] Please see Figure 1 and Figures 3-4 In this embodiment, the needle storage chamber 2 is provided with a needle outlet at the bottom, and an adjustable needle outlet gate is provided at the needle outlet. The guide frame 3 is connected to the needle outlet at the bottom of the needle storage chamber 2. The width of the needle slot 51 matches the diameter of the needle roller. The limiting block 52 is made of rubber. The upper end of the feeding worktable 1 is provided with a servo motor 7 with a concentric structure with the needle dispensing turntable 5. The output shaft of the servo motor 7 is fixedly connected to the lower end of the needle dispensing turntable 5. The lower end of the needle dispensing turntable 5 is fixedly connected with a ring-shaped support slide plate 8 that is evenly distributed. The upper end of the feeding worktable 1 is provided with an annular groove 9 that matches the support slide plate 8. The upper end of the feeding worktable 1 is fixedly connected with a guide support frame 10 that is symmetrically distributed about the front and rear of the push needle rod 4. A guide sleeve 11 that is sleeved on the outside of the push needle rod 4 is fixedly connected between the two guide support frames 10.

[0023] Please see Figure 4 In this embodiment, the chamber cover 12 is connected to the needle storage chamber 2 by a hinge. The needle storage chamber 2 is made of stainless steel and has a viewing window 13 made of transparent organic glass. A first support frame 14 is fixedly connected to the feeding worktable 1 on the outside of the needle storage chamber 2. The guide frame 3 adopts an inclined design with a lower front and higher rear, and an anti-collision pad 15 is installed on the inner wall of the front side of the guide frame 3. Limiting plates 16 are fixedly connected to both the left and right ends of the guide frame 3. A second support frame 17 is fixedly connected to the feeding worktable 1 at the lower end of the guide frame 3. The distance between the limiting plates 16 matches the length of the needle roller.

[0024] During operation, the needle rollers are pre-stored in the needle storage chamber 2. The viewing window 13 is used to observe the remaining needle rollers in the needle storage chamber 2 to prevent empty operation. The chamber cover 12 can be opened and closed by hinges to facilitate the replenishment of needle rollers. The needle rollers fall naturally to the bottom outlet by gravity. After sliding out from the bottom of the needle storage chamber 2, the needle rollers enter the guide frame 3. The first support frame 14 ensures that the needle storage chamber 2 is stable and does not shake. The guide frame 3 adopts an inclined design with a lower front and higher rear, using gravity to make the needle rollers slide naturally to the push position. The limiting plate 16 prevents the needle rollers from deviating and ensures a single row arrangement. The anti-collision pad 15 buffers the impact of the needle rollers and avoids surface damage. The second support frame 17 fixes the guide frame 3 to maintain structural stability. The drive motor 64 is powered on and drives the sprocket 65 on its output shaft to rotate. Through the meshing transmission chain 66, the sprocket 65 on the other side rotates synchronously, so that the transmission chain 66 moves in a straight line in a circular motion, connecting... Block 68 is fixed on the transmission chain 66 and drives slider 67 to slide along linear track 61. Slider 67 is connected to pusher rod 4, so that pusher rod 4 makes reciprocating linear motion in the horizontal direction. Guide sleeve 11 ensures that the movement trajectory of pusher rod 4 is accurate and avoids deviation. When pusher rod 4 pushes forward, it pushes the needle out from guide frame 3 and into the needle slot 51 of needle distribution turntable 5. Limit block 52 ensures that the needle falls accurately into the needle slot 51 and prevents deviation or jamming. Servo motor 7 drives needle distribution turntable 5 to rotate, so that each needle slot 51 moves to the next station in sequence. Support slide plate 8 slides along annular groove 9 to ensure smooth operation of needle distribution turntable 5. Vibration generated by pusher mechanism during operation is absorbed by shock absorber pad 69 to ensure smooth operation of equipment and reduce noise and wear. Pusher rod 4 returns to its original position and waits for the next batch of needles to enter guide frame 3. The above steps are repeated to realize continuous automated feeding.

[0025] Through the above steps, the needle storage chamber 2 is equipped with an adjustable needle gate at the bottom to precisely control the falling speed of the needle rollers, avoiding accumulation or uneven feeding. The guide frame 3 adopts a front-low, rear-high inclined design, which, together with the limit plate 16, ensures that the needle rollers are arranged in an orderly single row, reducing needle jamming or incorrect posture. The needle pushing mechanism uses a combination of chain drive and linear track 61, which provides more stable pushing force compared to cylinder drive, avoiding needle pushing not in place or overshooting. The needle slot 51 on the needle dividing turntable 5 ensures that the needle rollers fall accurately, while the rubber limit block 52 can prevent rolling. The design of the needle collision damage is optimized by combining the needle storage chamber 2, guide frame 3, needle pushing mechanism and needle distributing turntable 5. This effectively solves the problems of needle overlap, crossing, incorrect posture and cylinder thrust fluctuation caused by the traditional vibratory conveyor, resulting in needle push not being in place or overshooting. It significantly improves the feeding speed and stability. This solves the problem that the existing feeding device is prone to overlapping, crossing or incorrect posture in vibratory conveying, which requires multiple adjustments, resulting in delayed feeding cycle and poor feeding. In addition, the cylinder thrust fluctuation can cause needle push not to be in place or overshooting.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
