 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. 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.
(Note 3) Operating environmental conditions
Operating ambient temperature

0 to 40C

Operating ambient humidity

No flammable gas and corrosive gas are permitted.
To be operated indoors.

 User observance items[1] Conduct all operations of the machine including run, maintenance and repair in accordance with
instructions given in this Instruction Manual.
[2] Be fully careful to avoid such operations as to jeopardize the safety of the NTN bowl feeder. If a signof change liable to jeopardize the safety of the machine should be found, inform NTN to that effect.
(Note)

Ensure installation, operations, maintenance and repair of the NTN bowl feeder byprofessional engineers. In addition, ensure that the machine is not operated by any person otherthan those concerned.

3. Operating Principles
NTN bowl feeder is designed to magnetically vibrate a bowl and a lower vibrator coupled to eachother with 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 the leaf spring is so set that the vibration may be nearly resonant to the suction frequencyof the vibration magnet. Accordingly, a large vibration can be put forth with small exciting force.

the operation panel.)(5) Turn the speed adjusting knob of the controller slowly clockwise to set the graduation at a workpiece
speed that matches with supply capacity. Operate this machine under the maximum acceptable
amplitude of leaf spring in the item 8 in order to prevent breakage of leaf spring.

-7-

(Note 1) 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.
(Note 2) 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.
(Note 3) 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.
(Note 4) 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.
(Note 5) For details of required operation of the controller to be used, refer to the Instruction Manual
for the bowl feeder controller.

8. 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
and total the readings of upper and lower amplitudes.

[2] Caution in attaching and detaching leaf spring
When attaching and detaching the leaf spring, be sure tocomplete one unit before moving to the next unit. Do notloosen all the units at the same time.
a) Change the bolt length according to the increase or
decrease in the number of springs on assumption that
required bolt bite length (Dimension L includes thedimension on the upper vibrator side) is at least 2 times
as large as screw diameter (at least 8 mm for K10).
Tighten bolts securely while referring to the tightening
torques shown below as standard values.

[3] Retightening
Check the leaf spring tap bolts (or nuts) after actual run for about 40 hours, and retighten the bolts.
When the bolts have been tightened to normal torque, there hardly is allowance for additionaltightening, but consider this requirement as retightening to ensure comfortable fitting of leaf
springs.
[4] Correction of fatigue
When the SPEED ADJ. volume come to be used at the max. position at all times, add one or twopieces of leaf springs to any one place of the leaf spring unit.

-9-Even if the leaf spring mounting bolts are fastened normally, the spring constant of spring itself
may reduce owing to repetitive stress resulting from vibration after the machine is run for 40 to
100 hours. As a result, the amplitude may decrease negligibly.
[5] Replacement of leaf spring
Replacement of all leaf springs is recommended after run of the machine for 1 year on the basis of
8-hour run a day as a guideline.
If the amplitude cannot be recovered even after correction of set in fatigue in the paragraph մ
above, it is considered that the leaf springs have reached the end of life. 100% replacement ofleaf springs is recommended.
(Note) When new leaf springs are required, place an order with us while referring to the part No. ofthe 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 (K10 is upper vibration) is set to a value
shown in the following table when the body is shipped from NTN. But, since minimization of theclearance is advisable to the extent not to allow contact of them with each other at the occasion of
maximum amplitude, check the 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.

Clearance gauge
Clearance<Adjusting method>
Insert a clearance gauge of 0.1 t to 0.6 t into theclearance in the magnet as shown, and adjust theclearance at the oblong hole in the leaf spring in
the case of K10 and the circle hole in the leaf
spring in the case of K14, K16 or K20.
Check after adjustment of the clearance that theclearance between the top vibrator and the bottom
vibrator is uniform in the forward/backward andright/left directions.

(3) Change of power frequency
The power frequency of the NTN bowl feeder is adjusted in conformance to the value applicableto the 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  60 Hz: Increase the number of leaf springs by about 40%.
60 Hz  50 Hz: Decrease the number of leaf springs by about 30%.
<For information: How to check the number of leaf springs for surplus or shortage>
Check according to the following method whether the number ofleaf springs currently mounted is excessive or short for the bowl
and the alignment mechanism used.
Slightly loosen the leaf spring mounting bolt located at one place
while allowing continuous vibrations of the machine, and checkthe amplitude.
• Amplitude increased.  Number of leaf springs is too large.
• Amplitude decreased.  Number of leaf springs is too small orproper.
Optimum number of leaf springs is that sufficient amplitude isensured and that the amplitude decreases when the bolt isloosened.

[2] Changeover of frequency in controller
Set the frequency as shown below. For details, refer to the Instruction Manual for individual
controllers.
