Introduction

The Process flow of Automatic cut to length line:The steel sheet is uncoiling, then it goes through six high levellers, sensor-controlled looping, a length feeder that measures the length of the sheet, and shear control that cuts the sheet to the desired length; When the quantity of cut sheets is reached, press a button on the panel to switch the sheets to the second stacker. The cut sheets are delivered by the belt conveyor to the first stacker, where a scissor table automatically descends as the piled sheets height increases on the table. Press the button to cause the output roll table to deliver the sheets to the operation side after the scissor table has lowered to the bottom. In this manner, a single steel coil cutting is done continuously.

 

Products Description

The process of uncoiling , leveling , cutting , stacking is automatic without stretch tension to the sheet .

The control system is PLC servo control and HMI touch screen , the operator input the cut length and quantity, set feeding speed, auto and manual exchange , feeding length , feeding pieces , automatic start , automatic stop, pause , counter reset , forward , backward , shear up , shear down , abnormal alarm , etc .

Sheet surface protection is nicely noted on the cut to length line, like hard chrome coating , PU rubber coated roller , PU receiving arms , etc .

Servo Shearing machine: Servo motor controls shearing action, low noise and less piping. Servo adjusting blade gap with memory function can realize fast blade gap adjusting. The shear can act alone to meet length checking online

Stackers: The positions of baffle plates are in servo control: the operator set sheet length and width on the touch screen, press a key, the positions are automatically adjusted, meanwhile can finely adjust .The scissor table going down automatically in photoelectric sensor or thickness mode, can switch between the two modes for wood pallet or steel frame support piling.The correlation photoelectric sensor for receiving arms can avoid wrong action of the arms caused by laminated paper or film on sheets.
