Actions such as conveying, lifting, pick and place and other automated functions represent one or more axes of rotary motion found in material handling equipment. For accurate control, often a rotary shaft encoder is a preferred sensor for motion feedback.
Many material handling functions are often driven by servo or vector duty motors. These usually have integral encoders for closed loop motion control feedback. Alternatively, the encoders can be applied to a non-motor axis. Both incremental and absolute encoders are widely used in material handling equipment.
The Material Handling industry typically uses encoders for the following functions:
Motor Feedback - Conveyors, automated guided vehicles, forklifts
Conveying - Drive motors, head roll shafts, belt speed monitoring
Registration Mark Timing - Automated palletizers, shrink wrappers, case packers, pick and place robotics
Backstop Gauging - Gantry systems, automated palletizers
X-Y Positioning - Pick and place robotics, palletizers, case packers
1. Marble introduction
Marble originally refers to the white limestone with black patterns produced in Dali, Yunnan Province. The profile can form a natural ink landscape painting. In ancient times, marble with formed patterns was often selected to make screen or mosaic painting. Later, the name marble gradually developed into limestone with various colors and patterns and used as building decoration materials, White marble is generally called white marble. Marble is mainly used for processing into various shapes and plates for walls, floors, platforms and columns of buildings. It is also often used as materials for memorial buildings such as steles, towers and statues.
2. Marble material characteristics
Marble worktable is a kind of granite plate. It is made of "Jinan green" stone by mechanical processing and manual fine grinding. Black luster, precise structure, uniform texture, good stability, high strength, high hardness, can maintain high precision under heavy load and general temperature, and has the advantages of no rust, acid and alkali resistance, wear resistance, no magnetization, constant type and so on. Granite plate is suitable for measuring tools in machinery factories. After hundreds of millions of years of natural aging, the shape is extremely stable, and there is no need to worry about deformation due to conventional temperature difference. After strict physical test and selection, the granite has fine crystal, hard texture, compressive strength of 2290-3750kg / cm2 and hardness of Mohs hardness grade 6-7.
3. Benefits of marble materials
1. No deformation: after long-term natural aging, the rock has uniform microstructure, minimal linear expansion coefficient and complete disappearance of internal stress.
2. High hardness: good rigidity, high hardness, strong wear resistance and small temperature deformation.
3. Long service life: no need to apply oil, not easy to stick to dust, convenient and simple maintenance.
4. No scratch: it is not prevented by constant temperature conditions and can maintain its original physical properties at room temperature.
5. Non magnetization: it can move smoothly without stagnation, and is not affected by humidity. The plane scale is good.
I believe that after reading the above article, you have a further understanding of what is marble and the benefits of marble materials. I hope our introduction can be helpful to you.
