Chapter 6 Emergency Measures

If abnormal movements occur during mechanical operation, the operator can press the emergency stop button to stop the mechanical movement to ensure safety.

When the emergency stop switch is activated, attention should be paid to whether there is glass in the preheating section and heating section. If there is glass in the preheating section and heating body section, the glass in the furnace must be forcibly discharged to avoid overheating, softening, covering the surface of the quartz roller or falling into the furnace, causing damage to the quartz roller or reducing the service life of the electric wire.

After the emergency stop switch is restored, the original program of the device will no longer be executed, as long as a new cycle process is restarted.

After the glass enters the furnace and starts heating, if glass breaks in the furnace, the operator should follow the following steps:

(1) Manually open the rear furnace door

(2) Press the emergency exit button to discharge the glass from the furnace. Be careful to observe if any broken glass is stuck in the rollers inside the furnace. If found, the belt on the stuck roller must be removed and allowed to rotate freely.

(3) Turn off heating and stop production.

(4) Turn off all power switches; (Preparing for furnace cleaning work)

(5) Raise the upper furnace body and cover. Lift out the roller and clean the broken glass shavings in the furnace. And remove the glass fragments that fell on the protective plate of the electric hot wire together. Attention, check if any broken glass has fallen onto the heating wire. If so, be sure to remove it.

(6) After removing the glass chips from the furnace, there may still be a large amount of fine glass chips attached to the quartz roller. At this time, maintenance and repair should be carried out on the quartz roller.

Attention: When the temperature inside the furnace exceeds 300 degrees, it is strictly prohibited for the operator to raise the upper cover of the furnace to cool down, in order to avoid unnecessary mechanical damage.
