Precautions for Safety

This machine is designed and manufactured as a parts feeder based on theconcept of trouble-freeness and labor saving. However, you are also highly
responsible for safety as a user. Be sure to fully read this Instruction Manual
before starting to operate the machine and strictly observe the safety
precautions given below. Further, don't fail to comply with the instructions on
the warning and cautions labels adhered to the main body of the machine.

WARNING

Indicates a potentially hazardous situation which, if not avoided, will
result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, will
result in minor or moderate injury or property damage only.

WARNING
The most hazardous points of the machine are electrical equipment. Be sure to connect
grounding cables to them. Otherwise, electric shock may be caused.
Never use the machine in atmosphere of explosive or flammable gas or where such gas
leaks. Explosion or fire hazard may be caused.

CAUTION
Do not use the machine at a place exposed to splash of water, outdoors, or place of
extremely lower temperature or high temperature and high humidity. (For the operating
environmental conditions, refer to the next page.)y This machine is heavy (for the mass, see specifications on in Paragraph 10).
Transport the machine carefully with care to prevent drop after wearing safety shoes.
y Fix the machine securely after installation.
y Do not conduct the installation and assembly work with bare hands.
y Do not touch a chute provided with alignment mechanism with bare hands withattention paid to sharp edges. Be sure to wear gloves.
Do not use the machine on a base lacking in strength or at an unstable place. Otherwise,
specified performances cannot be exhibited.
Do not install the main body in inclination. Otherwise, specified performances cannot
be exhibited.
Please do not scratch, pull or forcibly bend the wiring. Moreover, when a heavy thing is
put on it, or it is pinched, the wiring will damage. It causes a fire or an electric shock.
When welding is intended to a chute, be sure to connect the grounding clip of thewelding machine to the chute securely. Incomplete grounding for welding may cause
the grounding cable connected from the main body to the controller to burn, leading toelectric shock or current leak.

Operating Principle

The chute installed on the upper vibrator is connected to the lower vibrator by means of the leaf springprovided at a certain angle, and they are vibrated with a magnet, so that works on the chute are thrown
upward aslant, resulting in little-by-little advancement of the works.
Large vibration can be generated with small oscillating force, since resonance is made to the suction
frequency of the magnet with strength of the leaf spring set properly to the mass of the chute.

Transportation and Installation
CAUTION
The machine is heavy. Transport the machine carefully with care not to cause
drop.

(1)

Transportation
If the machine is transported while holding
the chute, the chute or leaf spring may be
deformed. Be sure to hold the base or themain body.

 Precautions for transportation
The machine is heavy. When transporting it, conduct the work carefully with care not to allow drop.
For the mass of the main body (adding the mass of chute if attached), refer to Paragraph 10"Specifications".
(2) Installation
Fix the base with bolts securely. In the case of the fixed type of S05, mount the base on an iron plate of atleast 10 mm in thickness, since vibration-proofing function is not provided.
An advisable mounting method is that vibrations are hardly felt when you touch the base during operation.
Note) Do not allow the base to lose loss of hold as a result of use of undersize bolts. Do not mount thebase on a thin iron plate of less than 10 mm. Do not mount it at an extremely high position.
Precautions for installation[1] Assemble and set the machine with sufficient care not to cause deformation of the chute and thespring vibration isolator.
[2] Wear safety gloves so that you may not touch sharp edges of the chute with naked hands.
[3] Do not use the machine on a base lacking in strength or at an unstable place.
[4] Do not fix the machine with the vibrating portion (other than the base) of the machine coming
into contact with anything else.
[5] If the machine should be installed in inclination, specified performance cannot be exhibited. Be
sure to check the level of the installed machine.
[6] When execution of welding work or grinding work is intended in the vicinity of the linear feeder,
fit a protective cover to the entire linear feeder. Otherwise, iron powder and others may infiltrate
to spoil performance of the machine.

(Confirm lighting of LED on the operation panel.)(5) Slowly turn the speed adjusting knob clockwise to set the pointer position to the scale of the speed
corresponding to the feeding capacity. Operate the machine at amplitude lower than the maximum
allowable amplitude of leaf spring specified in Paragraph 8 to prevent break of the leaf spring.

-7-

(Note 1)

When it is intended to assemble the machine with other device, do not turn ON/OFF the linear
feeder on the primary side of the controller but use an external control input terminal.

(Note 2)The power connection work shall be executed by persons in charge of electrical engineering.
Where modification or change of wiring connections is intended, conduct the work whilereferring to the Instruction Manual of the controller.

(Note 3)

When a chute that matches with the shape of specified parts is installed, and indication mark is
found around the controller speed adjusting knob, set the adjusting knob at corresponding
position in use.

(Note 4)

When it is intended to extend the load cable of the machine by your company, use a cable of 2.5
mm2 min. in diameter and 10 m max. in length. Further, conduct a protective continuity test to
make sure that the machine is grounded appropriately.

(Note 5)For detailed operation of the controller to be used, refer to the Instruction Manual of thecontroller.

Inspection and Adjustment
Counterweight(1) Adjustment of counterweight
If the parts feeding speed is uneven on thefront and back on the chute, move thecounterweight back and forth for adjusting.
(Note) Tighten the counterweight position
adjusting bolt securely. Also make surethat the sphere of movement of thecounterweight is shown in item 5
Dimension Drawing on page 5.

Counterweight
position adjusting bolt(2) Inspection and adjustment of leaf spring[1] Maximum allowable amplitude of leaf spring
Operate the machine at amplitude lower than the value shown in the following table to prevent breakof the leaf spring.
If the machine should be operated at higher amplitude, the leaf spring may break at an early date. For
measurement of amplitude, attach the amplitude marking labels provided as shown below, and be
sure to total the readings of the upper and lower amplitude marking sheets.

When attaching/detaching the leaf spring, be sure to attach/detach the leaf spring in one leaf spring
unit and then proceed to the next unit. Do not loosen all units at one time.
a) The required bolt bite depth (Dimension L includes bite depth on the upper vibrator side) shall be
1.5 to 2.1 times as much as the screw diameter (As to S05 and S08, the bolt bite depth shall be
7.5 to 10.5 mm, since M5 screws are used). Change the bolt length according to increase or
decrease in the number of leaf springs. Tighten the bolts to the torque specified in the following
table.
(Note) As to S05, strictly observe the bolt bite depth specified above, since interference may takeplace with the moving iron core or the magnet when the bolt bite depth is 11 mm min.

Check the leaf spring mounting bolts to retighten them after actual operating time of 40 hours.
When the bolts are tightened normally, there hardly is the additional tightening allowance. But,
consider this requirement as retightening to cope with comfortable fitting of the leaf springs.
[4] Correction of set in fatigue
When the machine comes to be operated with the speed adjusting knob set to the MAX. position at
all times, add 1 or 2 pieces of leaf springs to a leaf spring unit located at any one place.
Even if leaf spring mounting bolts are tightened normally, the amplitude may reduce slightly after
operation of the machine for 40 to 100 hours due to reduction of the spring constant of the leaf
spring itself resulting from repetitive stress caused by vibrations.
[5] Change of leaf spring
A 100% change of leaf springs is recommended with the guideline of 1-year operation on the basisof operations of 8 hours a day.
If normal amplitude cannot be recovered after correction of the set in fatigue as described in [4]above, we recommend that you change all leaf springs, considering that the end of the life of the leaf
spring has been reached.
(Note) When new leaf springs are required, purchase them after referring to the leaf spring partNo. shown in Paragraph 10 "Specifications".

(3) Check and Adjustment of magnet clearance
The clearance between the magnet and the moving iron core is duly set as shown below before shipping of
the main body from NTN. But, it is advisable to narrow the clearance as much as possible within the range
not to cause touch of the magnet with the moving iron core during operation of the machine at the
maximum amplitude. Thus, check the magnet clearance from time to time to keep an appropriate value.
In operations under the atmosphere of much powder and others, such foreign matter may stick solidly on
the magnet and the moving iron core to narrow the clearance, resulting in generation of unusual noise.
Conduct periodic check to remove such foreign matter.

Magnet clearance<Adjusting method>[1] Loosen the moving iron core mounting bolts (2 places on the top of the upper vibrator).
[2] Insert a clearance gauge of 0.5 mm into the magnet clearance through the adjusting hole in the cover.
Push the moving iron core toward the magnet side, and fix the moving iron core temporarily.
[3] Tighten the moving iron core mounting bolts. At that time, take care so that the position set in [2] may
not deviate.
[4] Pull out the clearance gauge. (Check that the magnet clearance value is not deviated.)

CAUTION
When the machine is operated at the magnet clearance of at least 120% of the
maximum value specified above, the magnet may burn. Check the magnet
clearance from time to time to keep an appropriate value.

(4) Change of power frequency
NTN linear feeder is adjusted in conformance with the power frequency applicable to the district where it is
to be used or the set frequency on the controller. Accordingly, normal vibrations cannot be attained, if thepower frequency being the driving output frequency or the frequency set on the controller is different. Tochange the power frequency, follow the procedure specified below.
(Note)

Where the driving output frequency is set on a frequency variable controller, change of thesetting is not required, even after the power frequency (50 Hz⇔60 Hz) is changed.

[1] Change of the number of leaf springs
50 Hz → 60 Hz: Increase the number of leaf springs by approx. 40%.
60 Hz → 50 Hz: Decrease the number of leaf springs by approx. 30%.
<For information: How to check excess or deficiency of the number of leaf springs>
Check according to the following method if the number of leaf
springs currently mounted is too large or too small.
Loosen the leaf spring locking bolt at one place only whileallowing vibrations so as to check the amplitude.
y Amplitude increased → No. of leaf springs is too large.
y Amplitude decreased → No. of leaf springs is too small or
adequate.
Optimum state is that sufficient amplitude is attained and that theamplitude decreases when the bolt is loosened.

Troubleshooting
If a trouble should take place, check the following points.

(1) No vibration at all
In this case, locate the cause with the trouble contents divided into the mechanical system and theelectrical system.
Insert an iron piece in the magnet clearance as shown below with the POWER switch turned ON.

[1] Strong suction in vibration
The electrical system is normal. The cause lies ineither wrong setting of bowl feeder leaf springs orwrong designation of the frequency.
[2] No suction at all
The electrical system including the controller andthe magnet is problematic. But, in the case of acontroller with sensor, it is possible that thedetection head is in detection of a work. This is nota trouble. Conduct adjustment of the optical axis orcheck the near-by distance and others again.

Iron scale or the like
Magnet clearance

As to the electrical system, check the following items as well for the sake of confirmation.
a) Correct connection of power (Refer to Paragraph 7 "Wiring and Operating Methods").
b) Fusion of controller fuse and working of overcurrent protective functionc) External control input terminal of controller is shorted by short-circuit fitting, or is closed byexternal control. (See the controller operation manual.)d) Magnet coil is not broken.
