Directional transmission method and device suitable for L-shaped valve rod

Abstract

The invention relates to the field of automatic machining suitable for L-shaped valve rods, in particular to a directional conveying method and device suitable for an L-shaped valve rod. According tothe directional conveying device suitable for the L-shaped valve rod, a hopper movement mode is set, and torsional movement is added in the vibration or up-down movement process of a traditional hopper. The L-shaped valve rod ascends along a spiral material groove in the hopper under the combined action of inertia force, gravity and friction force, and the L-shaped valve rod and a disc do upward torsional movement together. When the vertical component of the inertia force borne by the L-shaped valve rod is larger than the gravitational acceleration, the L-shaped valve rod jumps upwards along aspiral groove of the disc. When the vertical component is smaller than the gravitational acceleration, the L-shaped valve rod overcomes the friction force to slide upwards along the spiral groove. The movement enables the L-shaped valve rod to jump upwards along the spiral groove of the disc and slide upwards along the spiral groove by overcoming the friction force, the L-shaped valve rod slidesinto the material groove in the movement process, and thus automatic orientation of the L-shaped valve rod is completed.

Description

technical field [0001] The invention belongs to the technical field of industrial automation transmission, and in particular relates to a novel L valve rod rapid automatic directional transmission technology. Background technique [0002] Whether the production line is running normally will directly affect the production schedule, production efficiency and production cost. A well-run and optimized production line can greatly improve production efficiency and eliminate obstacles between various processing links in the production process of an enterprise. [0003] The loading and unloading of workpieces is a key part of the production line, and the speed of loading and unloading directly affects the production efficiency of the entire assembly line. Optimize and adjust the workpiece loading and unloading equipment to further upgrade the production flow, adjust and change in the direction of unmanned and automated, further liberate productivity and improve production efficienc...

AI Technical Summary

Problems solved by technology

like Figure 5 As shown, the L valve stem is small in size and has a special shape. Using a conventional hopper to transport and slightly vibrating, it is impossible to make the L-shaped valve stem accurately enter the trough; and during the transmission process, due to the smooth The lower end of the round tube, the L valve stem with the big head connecting section is very prone to rotation and transposition during the conveying process; at the same time, there must be a gap between the material trough and the L valve stem, so the L valve stem is rolling. It is inevitable to tilt and rotate. When the diagonal line of the L valve stem is close to or smaller than the cross-sectional width of the trough, there is a danger of being stuck or losing orientation.

[0005] However, due to production needs, it is necessary to arrange the L valve stems according to a specific posture and scale when loading materials, so as to complete the subsequent processing of the workpiece; therefore, the existing L valve stems cannot rely on machines for stable transmission, and manual correction is required After that, place it on the conveyor

[0006] It leads to high labor intensity for workers and is not suitable for modern production

At the same time, due to the small structure and irregular shape of the L valve stem, the requirements for workers' operation level are relatively high.

Workers perform repetitive operations, which are tedious and easily distracted, which can easily lead to low product accuracy and low pass rate
