Description

Technical Field

[0001] This utility model relates to the field of automated conveying equipment technology, specifically a cam lifting and transfer mechanism. Background Technology

[0002] With the continuous increase in labor costs for manufacturing enterprises and the continuous development of intelligent manufacturing, intelligent transmission equipment is increasingly being used in production, manufacturing, and warehouse management.

[0003] However, regardless of whether it is a synchronous belt, belt, double-speed chain, roller, or roller conveyor, all conveyor equipment will have different height differences due to space limitations or operating height requirements. Faced with this problem, most current solutions are cylinder lifting devices or motor-driven chain lifting devices. These methods are not only inefficient, but also cause some degree of conveying obstruction, affecting the transmission speed of the entire assembly line. Therefore, we propose a cam-lifting and transfer mechanism. Utility Model Content

The right side of the right conveying assembly bracket is fixedly connected to the conveying assembly drive motor. The output shaft of the conveying assembly drive motor is fixedly connected to the conveying assembly rotating shaft.

[0010] Furthermore, each of the vertical beams of the transfer base assembly is fixedly connected to a limiting plate, and the inner side of the conveying component bracket is slidably connected to the outer side of the adjacent limiting plate to prevent the conveying component bracket from shifting.

[0011] Furthermore, the cam assembly includes a small cam bracket, a small cam, and a small cam shaft. The small cam brackets are symmetrically fixedly connected to the opposite inner sides of the two conveying component brackets.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the product (or pallet) is transferred from the previous conveying equipment to this cam lifting and transfer mechanism, the conveying component drive motor drives the conveying component transmission chain to rotate, and the positioning pin extends to position it, realizing the transfer and positioning of the conveyed product. Then the conveying component is transferred to the fixed position throttled by the positioning pin component. At this time, the cam lifting component drive motor drives the two camshafts to rotate. The lifting cam rotates to lift the small cam, the conveying component bracket is lifted, and the product is lifted. Then the conveying component transmission chain rotates to send the product to the next conveying equipment at a different height. When lifting the product, the product is simultaneously conveyed to the next conveying equipment in this cam lifting and transfer mechanism, which can realize the lifting and transfer function without affecting the transmission speed and without causing stagnation.

[0017] This cam-lifting and transfer mechanism has a simple structure and can be installed between any two transmission devices with a height difference. It can be used in combination with other types of transmission devices and has wide applicability. Attached Figure Description

The two single-row sprockets 11 are driven to rotate synchronously. The cam shaft 12 rotates synchronously with the single-row sprockets 11. The lifting cam 14 rotates and lifts the vertically adjacent small cam 16. The whole assembly consisting of the conveying assembly bracket 22 and the small cam bracket 15 is lifted. The inner side of the conveying assembly bracket 22 is slidably connected to the outer side of the adjacent limiting plate 19 to prevent the conveying assembly bracket 22 from shifting. The product is lifted. Then, the conveying assembly drive motor 10 drives the conveying assembly transmission chain 8 to rotate again, conveying the product to the next transmission device at a different height.
