英语翻译
The Layer Forming Transfer is driven by an AC motor through a gearbox,supplied by a frequency
converter.During the working operations the motor runs only in the forward direction.For maintenance purpose or cobble clearing both directions of rotation are required with an inching speed of 5 % of the max speed.
Transport speed is set by the operator or determined by rolling schedule.The speed of the forming
chain transfer must always be set in order to avoiding material overlapping (speed can be different
from previous chain transfer in order to compact or separate bars from one transfer to the other).
The main drive runs frequency controlled without a sensor speed-feedback,when the length of the
product requires that the section move together,the synchronized movement will be provided by the automation control system.
The transfer is divided in sections.Each section is 12 m long.
Automatic sequence is as follows:
1.When the stacker area is placed in automatic,the layer forming chain transfer will start running in forward direction.
2.The layer forming chain transfer drive is commanded to stop if any of the following conditions
are detected:
Stop condition 1:
- Layer present at stop #1
- Layer present at stop #2
- Layer separator is up
- Layer present at stop #3 OR layer on deposit magnets
Stop condition 2:
- No material is detected at any of the following listed locations AND after a time-delay (time
based on length of chain transfer section and speed of transfer).
- Previouse chains transfer exit
- Layer forming chains transfer entry
- Layer forming separator zone
- Between stops #1 and #2
- Stop #2
- Between stops #2 and #3
- Stop #3
3.Cycle complete.
