■ Caution When Using Inverter

CAUTION16

1. Be sure to confirm that the power source voltage is within the rated voltage
range, before switching ON the power source. (Voltage exceeding the rated
voltage could cause fuming, abnormal noise, etc.)
2. Be sure to start and stop the conveyor with RUN/STOP switch. When startingand stopping the conveyor frequently in a short period (tact operation etc.), it is
impossible to start/stop the machine by turning on/off the power supply. In thiscase be sure to start and stop the machine by external signals. (Inverter
variable-speed type is different from speed controller’s, and the power supply
will trip.) Do not start and stop the conveyor excessively frequently. It may cause
machine failure or shorten its service life.
3. The RUN/STOP switch of inverter unit is not for turning the power on and off.
When leaving the conveyor unused for a long period, make sure that the mains
is off.
4. Do not run the conveyor at excessively low speed for a long period, or start andstop the conveyor excessively frequently. These may cause machine failure or
shorten its service life.
5. Do not touch the inverter radiator of side of inverter unit, and do not allow any
material to touch it, because of its high temperature.
6. Use the inverter unit within the permissible range of ambient temperature (from–10℃ to ＋40℃). Avoid freezing.
7. Pay special attention not to allow any foreign matter (dust, iron powder, etc.) to
get into the inverter unit.
8. Operating the motor using the inverter could cause noises from the inverter I/O
cables, motor, etc. Keep in mind that these could interfere with the correct
operation of other electronic devices. (In this case, noises and their effects canbe suppressed to some extent by providing the inverter I/O with a filter orotherwise shielding the power cable.)4-3. CHANGING DIRECTION OF CONVEYOR TRAVEL
1. Constant-speed TypeTo change direction of belt travel, remove control box cover and change electrical wiring connections asfollows:■ Removing Control Box Cover-For head drive type (control unit is a separate box), loosen cover fixing bolts(*1)(one bolt on each side)and remove the cover(*2) sideways. (If difficult, remove the entire control box from frame, and thenremove fixing bolts and cover. In this case do not loosen any of the other bolts on sides of control
box.)-For center drive type (control unit is included in drive unit), remove drive lower cover. (→See p.26 and28.)
NOTE: 1. After changing direction of conveyor travel, ensure belt is correctly aligned before starting
machine. For belt alignment adjustment, see p.20 to 24.
NOTE: 2. Do not change direction of conveyor travel frequently. It may cause machine failure.
2. Speed-controller TypeBy switching the forward/reverse switch on the operation panel from FWD to REV (or REV to FWD), thedirection of operation will change to the opposite direction.

TAKING UP THE BELT

When belt is slackened off, take up belt as follows:When adjusting take-up bolt make sure the conveyor
is stopped.
NOTE: For belt tension, see p.19.
Taking up the Belt of

HEAD DRIVE TYPE

● For frame depth of 30mm
On both sides of conveyor, loosen bracket attachment bolts(*2)(one bolt on each side). To move tailpulley and brackets(*1) outward, turn take-up bolts(*3) inside bracket underside grooves with a spanner.
Belt will then be taken up. When turning take-up bolts(*3), adjust them alternately, little by little, to keep
their movement lengths the same. Once adjustment is completed, retighten bracket attachment bolts(*2).
● For frame depth of 60mm
On both sides of conveyor, loosen bracket attachment bolts(*5)(2 bolts on each side). To move tail pulley
and brackets(*4) outward, turn take-up bolts(*6) inside bracket side holes with a spanner. Belt will thenbe taken up. When turning take-up bolts(*6), adjust them alternately, little by little, to keep their
movement lengths the same. Once adjustment is completed, retighten bracket attachment bolts(*5).

Taking up the Belt of CENTER DRIVE TYPE
Take up belt by turning right and left take-up knobs(*7) clockwise. When turning take-up knobs(*7),
adjust them alternately, little by little, to keep their movement lengths the same.

18

■ Belt Tension
Do not take up belt too much, but only to extent that belt does not slip on drive pulley, i.e. enough todrive belt.
NOTE: 1. Excessive belt take-up may overload motor or shorten service lives of belt, pulley, etc.
NOTE: 2. For lagged drive pulley, belt makes abnormal noise when slipping.
Standard belt expansion percentage

How to calculate belt expansion percentage
1) Slacken belt.
2) Mark any two points on belt surface and measure length
between them (ℓ).
3) Take up belt.
4) Measure length between two marks (ℓ1) again.

egℓ= 1000 mmℓ1= 1002 mm
Belt expansion percentage = 0.2 %■ Adjustment Using Intermediate Take-up Unit (for longer machines exceeding 6m in length)
HEAD DRIVE TYPE(Long take-up unit)
On both sides of conveyor, loosen frame attachment bolts(*2)(4 bolts on each side). To move tail pulley
and take-up side plates(*1) outward, turn take-up bolts(*3)(M6) with a spanner. Belt will then be taken
up. When turning take-up bolts(*3), adjust them alternately, little by little, to keep their movement lengths
the same. Once belt is taken up, retighten frame attachment bolts(*2).

CENTER DRIVE TYPE
(Intermediate take-up unit)
1． Fully loosen take-up knobs(*4) of drive unit. (Turn them clockwise.)
2．Take up belt by turning take-up knobs(*5) of intermediate take-up unit counterclockwise. When
turning take-up knobs(*5), adjust them alternately, little by little, to keep their movement lengths thesame.
3．To completely remove belt slack, turn take-up knobs(*4) of drive unit counterclockwise. Also adjust
belt alignment while turning take-up knobs(*4).

19

6BELT ALIGNMENT ADJUSTMENT

When belt is not correctly aligned, make adjustments as follows:

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

2. Positions of Drive Side Plates
Confirm that right and left drive side plates are symmetrically positioned. → See p. 29.
NOTE: If drive side plates are not positioned equally onright and left sides, it may cause belt deviation.
Be sure to check their positions before using
conveyor because side plates may have shiftedout of position in transit.

3. Dirt on Pulleys
Check drive pulley, head and tail pulleys, etc. for dirt. Remove any dirt and clean. (Remove drive
lower cover to check.)
4. Loading Condition
Improper loading, i.e. not-centered, may cause belt deviation.
5. Dislodgment of V-form Strip
For non-deviation models(SCV, SHV model, etc.), check if V-form strip
on belt undersurface has dislodged from V-form belt guidance grooves
on pulleys and rollers. (For center drive type, remove drive lower cover
to check.)

6. Belt Deviation
Check how belt is deviating before adjustment. Correct positions of the following parts whilerunning conveyor slowly, and then continue running it for a while to check any further belt
deviation.
-Take-up devices: Position and adjust them equally on right and left sides.
-Head and tail pulleys: Set at right angle to frame.

206-2. BELT ALIGNMENT ADJUSTMENT
Outline of belt alignment adjustment
When moving belt in direction of arrow, adjust each part as shown in figure below.
(To move belt in opposite direction of arrow, adjust each part oppositely to that shown below.)

NOTE: It is necessary to wait until belt running stabilizes after each adjustment step and to adjust beltalignment little by little. Belt running will not change immediately.

BELT ALIGNMENT ADJUSTMENT OF HEAD DRIVE TYPE
1. Adjustment Using Take-up Bolt of Tail Unit
● For frame depth of 30mm
On side to which belt is deviating, loosen bracket attachment bolt(*2)(1 bolt on one side). Turn take-upbolt(*3) inside bracket underside groove counterclockwise with a spanner. Tail pulley bracket(*1) willthen move outward on this side and belt will center itself. Alternatively adjust on opposite side. In thiscase, to move tail pulley bracket(*1) inward on this side, loosen bracket attachment bolt(*2) and turn
take-up bolt(*3) clockwise. Once adjustment is completed, retighten bracket attachment bolt(*2).
● For frame depth of 60mm
On side to which belt is deviating, loosen bracket attachment bolts(*5)(2 bolts on one side). Turn take-upbolt(*6) inside bracket side hole counterclockwise with a spanner. Tail pulley bracket(*4) will then moveoutward on this side and belt will center itself. Alternatively adjust on opposite side. In this case, to movetail pulley bracket(*4) inward on this side, loosen bracket attachment bolts(*5) and turn take-up bolt(*4)
clockwise. Once adjustment is completed, retighten bracket attachment bolts(*5).

21

NOTE: For small-diameter pulley type such as SMHM and SHMV models, make adjustments similarly to“● For frame depth of 30mm” above, i.e. on side to which belt is deviating, loosen bracket
attachment bolt(*8) and finely adjust take-up bolt(*9) inside bracket underside groove.

2. Adjustment Using Head Drive Pulley(1) On opposite side of chain cover, remove side cover attachment bolt(*1)(1 bolt) and side cover(*2).
(2) Loosen attachment bolts(*3)(4 bolts) of drive pulley.
(3) To adjust belt alignment, move drive pulley by turning adjustment bolt(*4).
(4) Once adjustment is completed, retighten attachment bolts(*3) of drive pulley. Reinstall side cover(*2)
with attachment bolt(*1).
NOTE: For adjustment using return roller etc., refer to adjustments of center drive type.

BELT ALIGNMENT ADJUSTMENT OF CENTER DRIVE TYPE
1. Adjustment Using Take-up Knob
On side to which belt is deviating, turn take-up knob(*5) counterclockwise. Belt will then be loosened on
this side and center itself. Alternatively turn take-up knob(*5) on opposite side clockwise. Belt will then be
taken up on this side and center itself.
NOTE: Looking from the conveyor center, if drive unit is attached on conveyor tail side, turn take-up
knobs in opposite directions to those shown in figure, below.

22

2. Adjustment Using Head or Tail Pulley● For frame depth of 30mm
On side to which belt is deviating, slightly turn adjustment screw(*6) of head (or tail) pulley bracket
clockwise. Pulley will then move outward on this side and belt will center itself. Alternatively, on opposite
side, if there is a space between pulley bracket and frame end, make adjustment on this side. In this caseslightly move pulley inward by turning adjustment screw(*6) counterclockwise.
● For frame depth of 60mm
On side to which belt is deviating, slightly turn adjustment screw(*1) in lower part of tail pulley bracket
clockwise with a hexagonal wrench. Pulley will then move outward on this side and belt will center itself.
Alternatively, on opposite side, if there is a space between pulley bracket and frame end, makeadjustment on this side. In this case slightly move pulley inward by turning adjustment screw(*1)
counterclockwise.

● For frame depth of 15mm
Loosen M5 setting bolt with a hexagonal wrench, andmake adjustment by moving pulley bracket. Onceadjustment is completed, retighten M5 setting bolt.

3. Adjustment Using Return Roller (if any return rollers are attached)
On one side, loosen return roller bracket(*3) attachment bolt(*4), and set return roller slightly diagonally.
Belt will then move to form right angle to return roller rotation axis.
NOTE: It is effective to adjust the closest return roller to tail pulley. (The closest return roller to tail pulleyalternates depending on direction of belt travel as shown in figure below.)23

4. Adjustment Using Snub Pulley● For frame depth of 60mm
Snub pulley adjustment plate(*1)(one plate on one side) is found above drive unit chain cover. Loosensnub pulley fixing screws(*2) and make adjustment by turning adjustment bolt(*3). Once adjustment iscompleted, retighten the fixing screws(*2).

● Using snub pulley of intermediate take-up unit (frame depth: 60mm)
Snub pulley adjustment plate(*1)(one plate on each side) are found on sides of intermediate take-up unit.
Loosen snub pulley fixing screws(*2) and make adjustment by turning adjustment bolt(*3). Onceadjustment is completed, retighten the fixing screws(*2).

5. Adjustment for Reversible Operation
First run belt in normal direction and make adjustments so that belt will center approximately. Next
reverse the running direction and make adjustments according to direction of belt deviation as follows:-When belt deviates to the same side in both normal and reverse operations: Make fine adjustments sothat belt will center.
-When belt deviates to the opposite side in reverse operation: First make adjustments so that belt will
center. Taking into account normal directional operation, slightly move belt back to the side of
deviation.
NOTE: 1. For reversible operation, it usually takes a long time to adjust belt alignment. Additionally it isrequired to cut off belt deviation margin thus reducing belt width.
NOTE: 2. It is difficult to make adjustments when belt width is as long as, or longer than machine length.
For reversible operation, it is recommended to choose non-deviation models such as SCV, SHV.
