Failure Analysis And Maintenance Method Of Automatic Banknote Binding Machine

Jun 03, 2022

1. The rise and fall of the coin pressing mechanism fails


(1) Reason


①The capacitor of the pressing motor is damaged


②The lifting solid state relay is damaged


③The drop limit optocoupler is damaged


④The light shield is deviated from the optocoupler


⑤The travel switch is damaged


⑥The coin press motor is stuck


(2) Treatment: replace the capacitor; replace the solid state relay; replace the optocoupler; adjust the position of the optical film and the optocoupler; replace the travel switch; rotate the motor clockwise with an Allen wrench


2. The coin pressing mechanism is not overwhelmed and rewinds in advance


(1) Reason


①The preloaded optocoupler is damaged


②When the optical plate and the preloaded optocoupler deviate from the position


③Poor contact or disconnection of the optocoupler cable


(2) Treatment: replace the optocoupler; adjust the position of the light shield and the optocoupler; re-weld and replace the broken wire


3. The strap is not tightened


(1) Reason


①Passive rotary light shield does not rotate


②The optocoupler is damaged and the contact is poor


(2) Treatment: Tighten the passive wheel that drives the light shield; replace the optocoupler


4. The incoming band is blocked


(1) Reason: there is a foreign body in the slip; the banknote binding belt is too bent; the belt is not smooth


(2) Treatment: increase the belt feeding parameters; tighten the screw on the pressure belt; change the banknote binding belt; check the internal smoothness


5. Tang ironing is not good


(1) Reasons: the hot head is burnt; the temperature of the hot head is wrong; the horizontal belt is not tightened


(2) Treatment: replace the ironing head; adjust the temperature of the ironing head; adjust the horizontal belt pressure pulley


6. The front door trembles badly in action


(1) Reason: The connector of the front door electromechanical is in poor contact


(2) Processing: reconnect the connection or replace the connector


7. The lower iron is not reset:


(1) Reason: the loss of spring elastic force becomes smaller; there is garbage in the guide grooves of the left and right glands


(2) Treatment: adjust the loose coin light shield downward; clear the garbage
