Line Overview The continuous transport of goods on the pipeline, the transport conveyor or conveyor, which generally includes traction elements, bearing components, drive devices, tensioning devices, diverting devices and supports. Lines can be divided into seven categories: belt line, plate chain line, multiple chain line, plug-in line, mesh belt line, suspension line and drum line. The pipeline has a large conveying capacity, a long distance, and can also complete several process operations during the transportation process, so the application is very extensive.
Line features 1. The chain line uses the chain as the traction and carrier to transport the material. The chain can use the ordinary sleeve roller conveyor chain, but also can use other special chain.
2. Large transport capacity, can carry larger loads;
3. The delivery speed is accurate and stable, which can ensure accurate synchronous delivery;
4. It is easy to realize the accumulation and transportation, which can be used for assembly line or as a storage and transportation of materials.
Mechanical lines have certain requirements on speed, torque, precision and dynamic performance. Our company currently has two kinds of servo drive systems, ESDA and ESDB, to choose from. Each power level has a variety of servo motor applications. Adapt to different rotational speed, torque and load inertia occasions. In this application, we have selected Erasmus ESDB-15AEA and 130EMA-060BE12 servo systems for our customers.

Servo Performance Analysis For the mechanical assembly line, we use the pulse + direction position command input method. To achieve the customer's speed and position requirements, change the motor speed by changing the electronic gear ratio. Let the pulse command frequency sent by the PLC be fixed at H, the speed of the motor. For R, the electronic gear ratio is G. In the case of the electronic gear ratio G=1, a pulse command frequency of H=1Hz is issued, and the rotation speed corresponds to 8r/min. R/8 is the value that the pulse command frequency should reach when the electronic gear ratio is 1. After the value is greater than the electronic gear ratio, it is the actually received pulse command frequency.
H=R/(8×G) G=R/(8×H)
Through the gear ratio and rigid adjustment, it has been able to guarantee accurate synchronous delivery and carry the load required by the customer.
Conclusion Eras servo has the characteristics of strong anti-interference ability, fast response, accurate positioning, etc., applied to the mechanical assembly line, to meet the requirements of the manufacturers on the operation of the stability, precision and other indicators, and reduce the production costs, improve production The efficiency fully embodies the advantages of Eras servo, and the end customer selects our company's servo system.
