GENERAL INFORMATION
COMPONENTS
Linear unidirectional feedersareused to transfer the parts delivered by afeeding unit to apick-up area, throughachannel fixed
to theupper tray.
This type of vibrator is also useful to have a number of orientedparts in store ”along thechannel.
Theparts flowing to theorienting device can beinterrupted by asensor system whenever the channel gets full, and restarted as
soon as some of the parts havebeen used.
Linear unidirectional feeders consist of three elements :
- A vibrating base equipped with one magnet.
- A conveyor channel.
- A control box, for feed control.
LINEAR UNIDIRECTIONAL FEEDERS
OPERATING PRINCIPLE
When electricalcurrentflows throughanelectromagnet,integral withamass,theleaf springsthat connect the vibratingbase to
thechannel bend.This reactionof the leaf springsgenerates amotionthat ultimately causes forward movement of thematerial
along the channel.
Beforeusing thevibrator, readthroughthis booklet carefully.Thisguide contains safety instructions forset-up,operationand
maintenance. All operations must be carried out in such a way as not to damage the components.
HANDLING AND TRANSPORTATION
The product is shipped in a wood box, fixed by means of small beams.
In order to protect theoperators involved inhandlingoperations, thevibrators whose weightdoes notexceed 15Kg must be
taken out the package using eye-bolt G (see fig. 2), mounted on the vibrators themselves.
SET-UP
Beforeinstalling the vibrator, makesure that set-up area is suitable fortheoverall dimensions,weight and working conditions of
the system.
The support must be rigid and well fastened.
If a support with unsuitable dimensions is used, it will start vibrating, causing incorrect operation of thesystem.
For fastening, use the threaded holes provided in the vibration-damping feet and / or bases according to the type of vibrations.
Please refer to Table 4, which specifies the dimensions of theholes to be drilled in thesupports.
START-UP
Store thisbooklet in asafe place forfuture reference.
The linear vibrator must beequipped with a control box, withpower and frequency suited to the vibrator it has to control.
If possible, thecontrol box should be installed in an airy room, since in these conditions the components last longer.
When the vibratorand its control box havebeen installed correctly and all checkshavebeen completed, theunit will be readyto
start.
Beforeconnecting theunit to the power mains, carry out the following checks:
- Mains voltage- it must be thesame as the valuewritten on the unit tag.
- Mains frequency - it must be the sameas the valuewritten on the unit tag.
- Power supply cable - its sizemust be suitable for the power input required by the unit.
- Ground connections as appropriate.
- Positioning with respect to a round automatic distributor or other units - the various channels must be laid out so asnot to
touch or clash against one another, to avoid damage or malfunctioning.
Important:Set-up and start-upoperationsmust becarried outby qualified personnel, who should read and understand thein-
structions reproducedin this booklet.
MOUNTING AND DISMOUNTING THE CHANNEL
Important: Before carrying out any operation, turn the power supply off.
When installing theunit,or during operationandmaintenance,it may benecessaryto dismount thechannel from thevibrating
base to remove it. To dismount it, proceed as follow :
DISMOUNTING:
For type CHTR 40-50-70-85/S-100/S, loosen the channel fastening screws and remove the channel from its support.
For type CHTR 50/S and CHTR 75/S, simply loosen thechannel fastening jaws to remove the channel.
MOUNTING:
Repeat the above procedure in reverse order, and be careful to re-position the channel in the original location.

MAINTENANCE
Important: All maintenance operations must be carried out by qualified personnel, who should read and understand the instruc-
tions reproducedin this booklet.
Important: Before carrying out any operation, turn the power supply off.
Important:Any burnsor overheating phenomenaindicate ananomalous operating condition. In such cases, immediately inves-
tigate to find the root cause of the problemin order to avoid affectingothercomponents. Innormal operatingcon-
ditions the components are warm, but never hot.
Unidirectional feeders do not require special maintenance operations.
It’s only necessary to clean the following items on a regular basis:
- Clean the airgap, removing all metal particles, that may alterthe natural vibration frequency.
To carry out these operations, do not use liquids, only use compressed air and a clean cloth.
•After washing and de-greasingthe channel,check it to evaluate its roughness. Afterprolonged operationtheroughness
may be reduced, and consequently theparts to befed would havealesser degree of adhesion. To restoretheoriginal
roughness level, simply carry out a light grinding or glazing operation.
•After these operations, it may be necessary to repeat the calibration procedure.
CALIBRATION
To calibrate thevibrator, checkwhetherthe airgap dimensionscomply withwhat isspecifiedin Table3,thenadjust thethrust
exerted by the leaf springs by changing the number of laminations in each set.
Theair gap is the gap between themagnet and thecounter-magnet surfaces. This clearance must beadjusted to obtain suitable
operatingconditions.
To adjust the air gap, proceed as follow:
-Loosen screws Vand slide in ashimas wide astherequired air gap,movethemagnet nearer tothe counter-magnet, then
tightenscrews V. While performing this operation,make surethat thefinal air gapwidth correspondsto thevaluespecified in
Table 3.
To carry out a further feed rate adjustment proceed as follows :
- Slowly loosen the lower fastening screws on a leaf spring set. This should vary the speed at which the parts are fed through the
channel. If thespeed decreases, add aleaf spring -aset at atime -until therequired performances are obtained. If thespeed
increases, proceed in the opposite way, and remove some leaf springs.
In normal operating conditions, the vibrator does not produce any noise. In case you hear a bang, stop the vibrator immediately.
Important:If the air gap is too thin,the magnet and counter-magnet may touch, thereby damagingeach other and producing
a deep metallic sound.
Conversely,if the airgapis toowide, thepowerinputexceeds thevaluespecifiedin Table3, thecoil mayget burnedand the
vibrationcontrol circuit damaged.
NOISE EMISSIONS
Depending on the materials fed through the channel, noise emissions may exceed 75 DbA.
In such conditions, a sound-proofing system is required.
TESTING
Both standard and custom-madeunits arecarefully tested before shipment. Custom-made devices arechecked for compliance
with the features specified in the contract.
Standard units are checked for compliance to our standards.
APPLICATIONS OF LINEAR UNIDIRECTIONAL FEEDERS AND CHANNELS
CHOOSING THE RIGHT VIBRATOR TYPE
In general, a vibrator type is chosen according to the channel length, and to the size of the parts to be fed.
Special attention must be paid to theconveyorchannel and its support, which must beheavy and rigid. In these conditions the
channel itself canvibrate without causinganomalous vibrations that may affect the operationofthe vibrator.Toachieve this aim,
we recommend following the drawing and specifications carefully.
If thevibrating channelis to beveryshort, linear unbalancedvibrators may also beused,suchastype CHTR 40-50-70. These
types however, are not equipped with vibration-damping devices, since the base functions as a reaction mass. As a consequence,
they must berigidly fastened to asupport with suitable dimensions and weight, so asnot to disperse vibrations to theground,
thereby reducing theefficiency of the vibrator itself.
As for theoverall dimensions and applicationsof thechannels,please refer to the Table1. Obviously these values were worked
out onthe basis of average configurations. Nevertheless,it is alwaysnecessary to calibrate thevibratoraccording to the above
procedure.
The required profiles can be made by the customers themselves, or be obtained from TUMAC warehouses.
