Replacing The Standard S-Vcs → Optional S-Vcs Switching Cylinder - JUKI KE-3010 Maintenance Manual

Replacing the Standard S-VCS → Optional S-VCS
8-2.
Switching Cylinder
1) Close the finger valve to shut down supply
of air to the machine.
2) Disconnect the air tubes
VCS sensor assemblies (see Figure
8-2-1).
3) Replace the cylinders with new ones (see
Figure 8-2-2). Assemble the components
so that there is no tendency for any load to
be exerted on the cylinders.
<How to adjust the air cylinder>
1) Assemble the VCS sensor (or the optional VCS sensor) so that the distance between the left
end surface of the air cylinder and the front end surface of the sensor is 22.5 mm (or the rear
end surface of the sensor protrudes from the right end surface of the air cylinder by 6.5 mm)
(see Figure 8-2-1). After assembling, check to make sure that the sensor performs detection
correctly.
2) Adjust the air cylinder so that the slide unit falls at the position of 7 mm when the cylinder is
most stretched. (See Figure 8-2-2.)
After the speed controller has been replaced, make the adjustment so that the VCS is
switched at 500 mm/s (reference).
