Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of automated equipment, and in particular to a rejection device used in high-speed production lines. Background Technology

[0002] Existing production line rejection devices typically use cylinders as their power source. Traditional cylinder rejection involves mounting a sheet metal or flat plate at the front of the cylinder. When the cylinder's solenoid valve receives a signal, it controls the cylinder push rod to extend, pushing the product off the production line before retracting. This rejection method is suitable for products with low speeds and where tilting during rejection is not required. Furthermore, it is limited by the rejection frequency and environmental factors, requires high air pressure, generates noise, and directly impacts the cylinder's lifespan.

[0003] Existing high-speed rejection systems on the market consist of multiple high-speed cylinders arranged in a row. Each cylinder has a nylon arc-shaped pusher plate, ranging in length from short to long, mounted in front of it. When the cylinder's solenoid valve receives a signal, it controls the cylinders to extend sequentially. The pusher plates in front of the cylinders form an arc-shaped track, and products flowing into this track exit the production line. However, because this rejection method uses high-speed cylinders, it is very expensive. Furthermore, the rejection frequency and environmental conditions directly affect the cylinder's lifespan, making each replacement particularly costly and impractical. Summary of the Invention

[0004] The purpose of this invention is to provide a rejection device for use on high-speed production lines to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a rejection device used on a high-speed production line, comprising a guide rail connected to a fixed plate, a movable block slidably mounted on the guide rail, a motor base fixedly mounted on the movable block, a base plate mounted on the motor base, a motor bracket mounted vertically on the base plate, a servo motor mounted on the motor bracket, and a synchronous pulley mounted on the output shaft of the servo motor; a driven shaft mounted on the horizontal end of the base plate, a rejection wheel fixed on the driven shaft, and a driven pulley provided at the end of the driven shaft; the synchronous pulley is connected to the driven pulley via a synchronous belt.

[0006] Compared with the prior art, the advantages of this utility model are as follows: This invention uses a servo motor connected to a synchronous belt to drive the rejection wheel to remove defective products from the production line. The driving force of the rejection device comes from the servo motor. The maximum theoretical speed of the servo motor is 6000 rpm, and the theoretical rejection speed can reach up to 360,000 times / hour. By adjusting the start acceleration time, stop deceleration time, acceleration and deceleration curve of the servo motor, the effect of rejecting defective products can be achieved.

[0007] As an improvement of this utility model, the movable block is provided with a locking rod. The purpose of this design is that the movable block can be used to adjust the forward and backward travel of the entire device, and after the position is adjusted, the locking rod is used to fix the movable block.

[0008] As an improvement to this invention, stop blocks are provided on both sides of the rejection wheel. The purpose of this design is to further fix the rejection wheel in a lateral position.

[0009] As an improvement to this invention, a sensing rod is provided on the synchronous pulley, and a sensor is provided on the motor bracket. The purpose of this design is to allow the sensing rod to pass through the sensor, and then calculate the position using the electrical signal from the sensor.

[0010] As an improvement of this utility model, a positioning hole is provided at the center of the rejection wheel, and a keyway is provided on the positioning hole. The purpose of this design is to fix the rejection wheel in place through the connection of the keyway.

[0011] As an improvement of this utility model, the rejecting wheel is provided with an impeller-shaped rejecting part. The purpose of this design is that the impeller-shaped rejecting part, similar to a cam, has a longer contact surface when it touches a defective product due to its curvature.

[0012] As an improvement to this invention, the rejection section consists of two parts, symmetrically arranged. The purpose of this design is to improve efficiency.

[0013] As an improvement to this utility model, the material of the removal wheel is polyurethane. The purpose of choosing this design is that polyurethane material is soft, has good shock absorption effect, and is tough, durable, and not easy to delaminate. Attached Figure Description
