(5) Angle adjustment of return trough
Tilt angle of return trough is adjustable within the range of ±1° with reference to 7.5°.
For angle adjustment, loosen front and back return trough adjustment screws at supporting point
side and movable side, and change within slide range of elongate hole at movable side. Then adjust
the trough position so that works flow smoothly, and fix firmly.
(6)Adjustment of leaf spring mounting angle for return trough
For leaf spring of return trough, the angle is adjustable in three kinds (17°, 21°[Initial value], 25°
)
corresponding to climbing condition of transportation parts. When adjustment is required, follow to
the following procedure.
①
Loosen return trough angle adjustment screws of supporting point side and movable side (don’t
dismount).
②
Loosen fixing screws of lower leaf spring mounting block at front and back.
③
Loosen fixing screws of
mounting frame (MD10: 2
locations, MD20: 3 locations,
MD30: 5 locations).
④
Loosen fixing screw of angle
setting spacer and dismount the
spacer.
⑤
Slide angle adjustment scale of
mounting frame to conform to
value of mounting angle and
tighten fixing screws of mounting
frame to fix.
⑥
Mount number of angle setting spacers of lower leaf spring mounting blocks at front and back in
the following table corresponding to mounting angle.
