Horizontal Sealing Device
Drive System
The drive system shapes the motion of the sealing jaws (D-Motion).
It is this motion that causes the sealing jaws to open and close around
a bag. The system includes a servo motor, a servo amplifier, gearing,
and crank arms. The servo motor turns the gearing which turns the
crank arms. The rotating crank arms cause the jaws to open and
close.
Figure 3.28
Shows how the opening and closing motion of the jaws is formed.
