 For correct operation of the machine[1] The NTN bowl feeder is a vibrating machine with a bowl equipped with the mechanism to align theorientation of specified parts to thereby align and feed parts in bulk state to a specified point of place.
Do not use the machine for other purposes such as material tests and as equipment such as sieve.
[2] Operate the NTN bowl feeder in accordance with instructions given in this Instruction Manual andthe Manual enclosed in the same package. For technical specifications, see Section 10 “Specifications”.
[3] For operation of the machine, be sure to use an NTN controller and bowl. Further, be careful toselect a controller, bowl and power supply conforming to the machine.
[4] The resultant noise level varies with specifications of the machine and materials of parts to be fed. If
the noise level should be in excess of the tolerance limit, take countermeasures against the noise suchas fitting of a noise shielding cover.
(Note 1)

Do not use the machine, when it is not in perfect condition (such as unusual noise, abnormal
vibration and omission of parts).

(Note 2)

Where the bowl is equipped with the mechanism to align specified parts, any parts other than
the specified parts cannot be charged.

Operating Principle

NTN bowl feeder is designed to magnetically vibrate a bowl and a lower vibrator coupled to each otherwith a leaf spring set at a certain angle of inclination. As a result of this rotary vibration, works are aslant in
the upward direction in the bowl to go forward little by little. The relationship between the bowl and theleaf spring is so set that the vibration may be nearly resonant to the suction frequency of the vibration
magnet. Accordingly, a large vibration can be put forth with small exciting force.

When the bowl feeder is used in assembly with another device or the like, do not turn On-Off
the “On-Off” switch on the primary side of the controller but make use of the external control
signal input terminal.
Ensure that the power connection work is executed by electrical engineers. When
modification or change of wiring is intended, be sure to refer to the Instruction Manual for thebowl feeder controller.
Where a bowl is provided with an alignment mechanism and an instruction mark is locatedaround the speed control knob of the controller, operate the machine with the speed control
knob position adjusted to the marking.
When extension of the load cable is intended by your company, ensure the extension length of
10 m max. in use of a cable of 2.5 mm2 min. in size. In addition, conduct the protective
continuity test to check that the machine is grounded appropriately.
For details of required operation of the controller to be used, refer to the Instruction Manual
for the bowl feeder controller.

Inspection and Adjustment(1) Inspection and adjustment of leaf spring[1] Acceptable maximum amplitude of leaf spring
To prevent break of the leaf springs, operate the machine at amplitude lower than shown in thefollowing table.
If the machine should be operated at higher amplitude, the leaf springs may break at an early date.
When measuring the amplitude, be sure to attach the supplied amplitude marks as shown below andtotal the readings of upper and lower amplitudes.

b) Place spacers between leaf springs,
and apply grease or rust preventative
oil between the spring and the spacer.
At that time, make sure not to include
dirt and chips between them.

Spacerc) Tighten the bolts to the tightening torques thatare specified as guide values in the table below.
Apply grease or rust-preventive oil to thewhole spring after adjustment of the springs.

Guide value of tightening torque: In the case of “Approx. 117.6 N·m” shown in the abovetable, the value roughly means tightening of a bolt to the level such as tightening underfull power with one hand using a tool of 300 mm in arm length.

[3] Retightening
Check the leaf spring mounting bolt and retighten it after actual operating time of about 40 hours.
When the tightening is normal, there is hardly the additional tightening allowance. But, consider thisrequirement as retightening of comfortable fitting of the leaf spring.
[4] Correction of fatigue
When the machine is operated with the speed control knob set to the MAX. position at all times, add
1 or 2 pieces of leaf springs to a leaf spring unit in either one place.
Even if a leaf spring mounting bolt is tightened normally, the spring constant of the leaf spring itself
may reduce due to repetitive stress caused by vibration, thus resulting in slight decrease in theamplitude, when the machine is operated for 40 to 100 hours.
[5] Replacement of leaf spring
100% replacement of leaf springs is recommended with the guideline of 1-year operation on thebasis of 8 hours a day.
If amplitude cannot be recovered after correction of set in fatigue described in [4] above, we
recommend that you replace all leaf springs, considering that the end of the life of the leaf spring has
been reached.
(Note)

When new leaf springs are required, place an order with us while referring to the part No.
of the leaf spring shown in Section 10 “Specifications”.

(2) Check and adjustment of clearance in magnet
The clearance between the magnet and the moving iron core is set to a value shown in the following
table when the body is shipped from NTN. But, since minimization of the clearance is advisable tothe extent not to allow contact of them with each other at the occasion of maximum amplitude, checkthe clearance from time to time to keep a proper value.
In a much dusty environment, such dust may stick to the magnet and the movable iron core solidly tonarrow the clearance, possibly resulting in generation of unusual noise. Conduct check to remove
dust and others periodically.

[2] Insert a clearance gauge of the dimension specified for each body (shown above) into the space
between the magnet and the movable iron core, and temporarily tighten the movable iron core
tightening bolt with the movable iron core pressed against the magnet side.
[3] Tighten the movable iron core tightening bolt to the specified torque. At this time, be careful sothat the position set in [2] above may not deviate.
[4] Pull out the clearance gauge. (Check that no deviation is present in the clearance between themagnet and the movable iron core.)[5] Attatch the cover.

CAUTION
When the machine is operated with the clearance in the magnet increased by 20% inexcess of the maximum value shown above, the magnet may burn. Check theclearance in the magnet from time to time to keep a proper value.

(3) Change of power frequency
The power frequency of the NTN bowl feeder is adjusted in conformance to the value applicable tothe area where it is used or the preset frequency for the controller. Accordingly, normal vibrations
cannot be ensured, if the power frequency or the preset frequency for the controller as the output
frequency for driving should change. When change of the power frequency is intended, strictly
observe the procedure described below.
(Note) Where the output frequency for driving is set on a variable frequency controller, change ofsettings is not required, even if the power frequency (50 Hz  60 Hz) is changed.
[1] Change of number of leaf springs
50 Hz o 60 Hz: Increase the number of leaf springs by about 40%.
60 Hz o 50 Hz: Decrease the number of leaf springs by about 30%.
- 12 -

<For information: How to check the number of leaf springs for surplus or shortage>
Check according to the following method whether the number of leaf
springs currently mounted is excessive or short for the bowl and thealignment mechanism used.
Slightly loosen the leaf spring mounting bolt located at one place whileallowing continuous vibrations of the machine, and check the amplitude.
• Amplitude increased. o Number of leaf springs is too large.
• Amplitude decreased. o Number of leaf springs is too small or proper.
Optimum number of leaf springs is that sufficient amplitude is ensured andthat the amplitude decreases when the bolt is loosened.
[2] Changeover of frequency in controller
Set the frequency as shown below. For details, refer to the Instruction Manual for individual
controllers.

If any trouble should be found, check the following points:(1) No vibration at all
In this case, distinguish the trouble between mechanical system and electric system as shown below
for checking.
Turn ON the POWER switch, remove the cover, and bring an iron piece close to the vicinity of themagnet core.
[1] When the iron piece is attracted strongly during vibration
Electric system is normal. Accordingly, the cause of the trouble
lies in either setting of the number of leaf springs of the bowl
feeder or wrong designation of the power frequency.
[2] When the iron piece is not attracted at all
Trouble of electric system including controller and magnet.
However, if the controller is equipped with a sensor, it ispossible that the detection head detects a workpiece. It is not atrouble. Align optical axis or recheck proximity distance, etc.

Scale made of iron, etc.

Further, check the following points for electric system for safety:a) Power supply is connected properly. (See the Section 7 “Wiring and Operating Methods”.)b) No melting of controller fuse and no working of overcurrent protective functionc) Shorting of the controller external control signal input terminals. Closing of the terminals
according to external control signal (refer to the Controller Instruction Manual.)d) Normal magnet (If a)–c) are normal, subject individual magnets to the attraction test shown
above.)(2) Vibration is found, although amplitude is insufficient.
