TAKING UP THE BELT

When belt is slackened off, take up belt as follows:
To take up belt, turn right and left take-up bolts clockwise with a spanner. Take-up pulley will then be
moved and belt will be taken up. When turning take-up bolts, adjust them alternately, little by little, tokeep their movement lengths the same. If belt is taken up too much, slightly turn take-up bolts
counterclockwise. When adjusting the bolts, make sure the conveyor is stopped.
NOTE: 1. Do not take up belt too much, but only to the extent that belt does not slip on drive pulley, i.e.
enough to drive belt. Excessive belt take-up may overload motor or shorten service lives of belt,
pulley, etc.
2. Belt occasionally shrinks depending on environment or type of belt. In this case adjust belttension by loosening.

SpannerTake-up bolt

■ Belt Tension
For belt width of 300mm or less, standard belt expansion percentage is determined to be 0.15-0.2%.
How to use standard belt expansion percentage
1) Slacken belt. (See p.16.)
2) Mark any 2 points in belt center and measure length between them (ℓ). (Set length ℓ to what you
can easily use.*)3) Take up belt until length ℓ becomes intended length ℓ1.
*Example of ℓ and ℓ1:
Setting ℓ to 1000mm → 1000mm×0.15%(0.2%)=1.5mm(2mm)→ Take up belt until ℓ becomes ℓ1, i.e. 1001.5mm(1002mm).

6-1. PRIOR CHECKING
1. Frame Condition
Confirm full length of frame is level on top, straight and not bent in any place.

Bent

Not level

Lopsided

2. Positions of Side Covers
Confirm that side covers A and B are symmetrically positioned.
NOTE: If side covers A and B are not positioned equally on each side, it may cause belt deviation.
Be sure to check their positions before using conveyor because side covers may haveshifted out of position in transit.

Side cover
Measure this length on
both sides to checkinstallation condition ofside covers A and B.
3. Dirt on Pulleys
Check drive pulley, head and tail pulleys, etc. for dirt. Remove any dirt and clean. (Remove undercover to check.)
4. Loading Condition
Improper loading, i.e. not-centered, may cause belt deviation.
5. Belt Deviation
Check how belt is deviating before adjustment. Set positions and lengths of right and left take-up
bolts equally while running conveyor slowly, and then continue running it for a while to check any
further belt deviation.

14

6-2. BELT ALIGNMENT ADJUSTMENT
1. Adjustment Using Take-up Pulley
On side to which belt is deviating, turn take-up bolt counterclockwise with a spanner. Belt will thencenter itself. Alternatively adjust on opposite side. In this case turn take-up bolt clockwise.
[Point of belt alignment adjustment]
It is necessary to wait until belt running stabilizes after each adjustment step and to adjust belt alignment
little by little. Belt running will not change immediately.
