Description

Technical Field

[0001] This application relates to the field of bushing processing technology, specifically to a feeding device for water meter bushings. Background Technology

[0002] Water meters are metering instruments installed on water supply pipelines to measure the volume of water flowing through them. Bushings are ring-shaped parts installed in water meters that provide protection, sealing, and wear resistance. The production of water meter bushings requires multiple processing steps. With the development of automation technology, current water meter bushings can be automatically fed into processing equipment using a feeding mechanism. However, because one end of the water meter bushing is designed with an outward-protruding stepped sleeve, and the direction of this stepped sleeve when entering the processing equipment is required, the existing feeding mechanism cannot automatically adjust the direction of the stepped sleeve. Therefore, it is necessary to manually observe the direction of the stepped sleeve on the water meter bushing during the feeding process. Once a water meter bushing is found to have a step sleeve that does not meet the requirements, it must be manually removed one by one. Therefore, the operation is cumbersome, time-consuming, and labor-intensive. Furthermore, manual inspection is prone to fatigue and has a high rate of missed inspections. In addition, the workload is high and the labor cost is high, which urgently needs to be addressed. Summary of the Invention

[0030] Working principle: A certain number of bushings 7 are placed horizontally on the conveyor belt 2. After the conveyor belt 2 is started, it will drive each bushing 7 to move backward. The above structure and principle are existing technologies. Since one end of the bushing 7 is designed with concentrically distributed stepped sleeves 71, the bushings 7 placed on the conveyor belt 2 are not manually aligned. Therefore, the stepped sleeves 71 on each bushing 7 are set to the left or right.

[0031] Next, the last bushing 7 will roll into the positioning groove 37. If the stepped sleeve 71 on the bushing 7 is set to the left, it does not need to be removed, and the stepped sleeve 71 will extend into the identification groove 371. Then, the telescopic end of the drive traction cylinder 35 will retract inward to drive the traction plate 33 to move to the right with the help of the seat block 313. Then, the pulley 34 will be forced to move synchronously with the help of the traction groove 331. When the pulley 34 moves, it will roll upward along the traction groove 331, thereby driving the sector conversion plate 32 to rotate counterclockwise. Then, the bushing 7 will rotate synchronously with the help of the positioning groove 37. When the outer wall of the original planar surface on the upper side of the sector conversion plate 32 is attached to the positioning plate 38, the sector conversion plate 32 can no longer rotate, and the bushing 7 has rotated exactly 90 degrees. During this process, the front outer wall of the sector conversion plate 32 is always blocked at the rear end of the conveyor belt 2, so the second bushing 7 will not roll off and will remain in place.

[0032] Next, the telescopic end of the pusher cylinder 44 in the drive ejection mechanism 4 extends outward to drive the pusher bar 43 to move backward, thereby causing the rear end of the pusher bar 43 to pass through the positioning groove 37 and extend into the guide groove 51, thus pushing the bushing 7 into the guide groove 51. The stepped sleeve 71 on the bushing 7 extends downward into the limiting groove 53 on the storage block 5. Then, the pusher bar 43 continues to be driven to move backward to push the bushing 7 to continue to move backward until it is blocked by the baffle plate 6. Due to the setting of the anti-tilting surface 52, it always has a tendency to tilt forward, but is blocked by the rear end of the pusher bar 43. The obstruction prevents the bushing 7 from tilting, thus maintaining a vertical position. This effectively prevents the bushing 7 from tilting backward due to inertia during movement. Simultaneously, since a portion of the lower end of the bushing 7 slides against the anti-tilting surface 52, it gradually rises during backward movement, causing the upper end of the bushing 7 to be higher than the top of the storage block 5. This facilitates manual or robotic removal of the bushing 7, achieving two goals at once. During the movement of the pusher bar 43, the two limiting inclined surfaces 433 never contact the anti-tilting surface 52. Once they do, the pusher bar 43 cannot continue to move backward, thus serving as a limiting function.

[0033] If the stepped sleeve 71 on the bushing 7 is set to the right, the bushing 7 must be removed. During removal, the sensing end of the position sensor 312 will first detect the stepped sleeve 71, and then start the removal motor 39 in the removal unit to rotate its rotating shaft, which in turn drives the worm gear 311 to rotate synchronously. This drives the inspection disc 310 to rotate clockwise with the help of the worm wheel surface 3101, which in turn causes the opening of the positioning groove 37 to gradually face to the lower right. Thus, the bushing 7 tilts to the lower right and falls out with the help of its own weight. After removal, the rotating shaft of the removal motor 39 will reverse to drive the inspection disc 310 to rotate counterclockwise in the same way until it returns to its original position. Then, it will wait for the next bushing 7 to roll into the positioning groove 37, and then drive the bushing 7 to rotate to the right or remove it again in the same way.

[0034] This invention can automatically identify the direction of the stepped sleeve 71 on the bushing 7 and automatically remove bushings 7 that do not meet the direction requirements. It eliminates the need for manual inspection and adjustment, thereby effectively simplifying the operation steps to achieve the effect of saving time and effort. At the same time, it reduces the workload, avoids missed inspections, and lowers labor costs.
