IMPROVEMENT EXAMPLES
@
Problem Dog adjustment is difficult.
Solution Separate each one until the dog
can be adjusted.
@
Problem The dog axis is too long, and slips
out during operation.
For this reason, the limit switch
operating position slips.
Solution Firmly fix the dog plate to the base.
r
@
Problem The detector sinks, applying force
to the limit switch.
The limit switch O.T. cannot be set.
Solution Relieve the pressure using an
additional actuator, and the O.T.
can also be set.
r
@
Problem The area around the actuator coil
is easily damaged.
Friction generated during opera-
tion.
Solution Relieve the friction by installing an
additional actuator.
Change the type of limit switch.
r
@
Problem Workers keep bumping the actua-
tor.
Solution Fit a protective cover to the side of
the limit switch.
r
@
Problem
Because the cord vent for the limit
switch faces upwards, water droplets
and so forth can easily penetrate the
interior.
The cord is constantly moving and
thus easily damaged.
Solution
Fix the limit switch position on the
stationary board.
Fit a protective cover, so that water
and oil cannot come into direct con-
tact with the limit switch.
r
@
Problem The cord is not fixed, and gets
pulled during work.
Dog adjustment is ineffective.
Solution Change the limit switch position,
and fix the cord.
Attach an adjustment mechanism
to the dog.
r
@
Problem The limit switch is near a high-tem-
perature area.
Dog adjustment is ineffective, and
the dog keeps bumping the lever.
Solution Move the limit switch further away.
Make dog adjustment possible,
and change the shape of the unit.
