Generally speaking, the sliding contact line is widely used in stackers, but with the continuous development of automated stereoscopic libraries, due to the technical limitations of the basic power supply principle of the sliding contact line, the drawbacks of the application are slowly emerging, such as the following situations:

1, the long-term use of copper conductor surface is easy to oxidize or accumulate dirt, need to be cleaned regularly, otherwise affect the effect of electricity;

2, brush and copper conductor friction will produce metal dust, causing pollution;

3, high-speed high-frequency operation, brush easy to wear, need regular maintenance;

4, sliding line power supply process will produce electrical spark;

5, high-speed operation in the brush and copper conductor contact instability: unstable power supply, data signal transmission is unstable, temporarily can not achieve Ethernet/fiber communication;

6. The safety protection of on-site personnel is worse, in case the power is not implemented in place, it is easy to cause electric shock accidents;

7, waterproof and dustproof grade is low, can not adapt to high humidity environment;

8, metal brackets and conductors are not corrosion resistant, can not adapt to a certain corrosive environment.

So, in the special environment of the automated stereoscopic library, the opportunity to tow chain system comes...

1, special use environment

Explosion-proof: ESD explosion-proof drag chain + metal guide groove + necessary grounding measures, safer than sliding contact line. Suitable for storage with certain explosion-proof grade requirements.

Dust pollution: The operation of the tow chain system does not produce metal dust, and will not pollute the semi-exposed materials stored. It is suitable for battery electrode library and semi-finished tire (birth tire) library.

Environmental resistance: Environmental dust (such as dust, graphite, etc.) is easy to adhere to the sliding contact conductor, resulting in poor contact or short circuit. Tow chain system is not afraid of dust, dirty environment adaptability.

Temperature tolerance: the drag chain is more reliable in low temperature, high temperature (electric cabinet can be external), and large temperature difference environment.

High humidity + corrosion: The drag chain system has excellent corrosion resistance. Waterproof and dustproof grade can reach IP67, suitable for high humidity warehouse.

2. Special function technology

1, stacker fork integrated special functions, such as with pneumatic device (clamping), suitable for irregular materials;

2, high-speed light stacker has the requirements of weight reduction and shock absorption (multi-layer three-dimensional library). Using the tow chain system, the stacker electric gas cabinet can be placed on the ground, reducing the weight of the whole stacker and reducing the load of the running motor;

3, three-dimensional library does not allow the use of wireless communication, and when the sliding line can not achieve Ethernet communication and optical fiber transmission. The requirements of certain military secrecy units;

4, the whole set of mobile power supply system has higher requirements: can be expanded, easy to install, maintenance-free (more than 5 years on average).

Product upgrading, choosing the right one is the most important thing. The above is the knowledge about the stacker brought by Xiaobian. For more details, please go to the official website to consult and understand.
