Inspection and adjustment of leaf springs for return trough
[1] The return trough leaf springs are shipped from NTN after assembly in appropriate number of
pieces. Adjustment of number of the leaf springs required for the feeder body leaf springs is not
required as a rule.
[2] Relating to change of leaf springs, 100% change of leaf springs is recommended on the yardstick of
1-year operation on the basis of 8-hour operation a day, same as operation of the feeder body. Where
new leaf springs are required, purchase them while referring to the leaf part No. described in the
"Leaf spring Part No." column in item 11 "Specifications".
(8) Coating
Return trough transporting works and coated surface of the chute mount will get dirty due to works
transported and transportation ability of works may be reduced. Check the coated surface from time to
time, and clean the coated surface with water or neutral detergent, if it is found foul.
9.
Fitting Work of Attachment
(1)
The tilt angle of the return trough inclined surface can
be adjusted by turning the angle adjusting screw
shown in item 4 "Names of Main Component Parts".
Adjust the angle to the climbing ability of works to be
fed.
Moreover, adjust the height of backing plate of feed
track (right figure) so that works do not outflow from
behind of the chute mount due to the mounting.
(2)
When climbing performance of trough is not ensured depending on works transported even if the body
was adjusted, bond commercially available belt material on the feed track surface.
