Installation
Installation Instructions
General
Connect the screw feeder to the mains using the delivered power supply.
Connect the external output signal line, as required.
DC maximum: 100 mA
Externally applied voltage 5 - 24 V
Max cable length: 3 m
OFF when no screw is present
ON when screw is present
Before delivery, each section of the machine is checked and adjusted with panhead screws matching the nominal diameters of the ordered model.
Most screws may be usable in the initial status of adjustment however, if the height or shape of the screw head is different or if the operation is regarded as abnormal, each section must be readjusted. If this is the case, make checks and adjustments according to the Maintenance section.
Operation
Ergonomic Guidelines
Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.
Take frequent breaks and change work positions frequently.
Adapt the workstation area to your needs and the work task.
Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.
Use workstation equipment such as tables and chairs appropriate for the work task.
Avoid work positions above shoulder level or with static holding during assembly operations.
When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.
Take frequent breaks.
Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.
Adjust for a convenient field of vision that requires minimal eye and head movements.
Use appropriate lighting for the work task.
Select the appropriate tool for the work task.
In noisy environments, use ear protection equipment.
Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.
Minimize exposure to reaction forces.
When cutting:
A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct flange for the cut-off wheel and avoid bending the cut-off wheel during operation.
When drilling:
The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high. The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
When using direct-driven screwdrivers or nutrunners:
Reaction forces depend on the tool settings and joint characteristics. Strength and posture determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.
In dusty environments, use a dust extraction system or wear a mouth protection mask.
Operating Instructions
Load screws
The figure indicates the maximum amount of screws to be loaded.
Turn the power switch ON and then turn it OFF when the scooping block is at the lower limit position.
Load screws up to 2 to 3 mm below the rail surface.
At this time, check that screws are not loaded so as to cover the upper portion of the inclined plate.
Power on
Turn the power switch ON.
Check that:
The power switch indicator lights up.
The rail starts to vibrate and the escaper starts rotating.
The scooping block starts to move up and down.
Screws move along the rail towards the rotating escaper which selects one screw at a time.
The escaper rotates and deposits the selected screw at the extraction site.
At this moment, the screw sensor indicator lights up and the operation stops, waiting for the screw to be extracted.
Service
Preventing ESD Problems
The components inside the product and controller are sensitive to electrostatic discharge. To avoid future malfunction, make sure that service and maintenance is carried out in an ESD approved work environment. The figure below shows an example of an appropriate service work station.
Maintenance Instructions
Clean the screw rail
A dirty rail groove may interfere with the screw transport speed.
-
Clean the rail with a soft, clean cloth dipped in aloohol.
If cleaning is difficult, proceed as follows:
Tum off the power supply.
Remove all screws from the chamber.
Remove the rail from the machine and clean the rail groove with a soft, clean cloth dipped in aloohol.
If the rail is damaged or can naot be cleaned, replace it.
Check and adjust the passing plate
Check that the passing plate is adjusted to a height that permits loaded screws to pass just within the clearance limit.
If the passing plate is too low. screws cannot pass.
If the passing plate is too high, it will hamper a smooth transport of the screws.
If adjustment is required, loosen the passing plate attaching screw and adjust the height.
After making an adjustment. do an operational check.
Check and adjust the holding plate
Check that the clearance between screws in the rail groove and the holding plate is about 0 ~ 1 mm.
If there is no clearance, a screw will be caught.
If the clearance is too large, a screw pile or screw jump will occur.
If any adjustment is required, loosen the holding plate attaching screw and move the plate up or down.
After making an adjustment, check the machine operation.
Check and adjust the rail vibration
The screw transport speed differs depending on the screw type.
Check the screw transport speed. If the rail vibration hinders a smooth transport of the screws, it needs adjustment.
Loosen the anti-vibration screw (A) at the rear of the machine
Turn the vibration adjusting screw (B) located on the bottom of the machine, to adjust the vibration.
When the screw (B) is turned clockwise, as viewed from the bottom of the machine, the vibration will increase
When the screw (B) is turned counterclockwise, the vibration decreases
After adjustment, be sure to tighten the anti-vibration screw (A).
Do an operational check.
Check and adjust the timer
The screw transport speed differs depending on the screw type. This machine uses a timer to make screw unloading smooth.
For screws with a low transport speed, set a longer time.
For screws with a high transport speed, set a shorter time.
Check the operation by intercepting the optical axis of the sensor.
Make an adjustment with the timer knob at the rear of the machine body.
When the timer knob is turned clockwise, as viewed from the rear side, the time becomes shorter.
When the knob is turned counterclockwise, the time becomes longer
Check this adjustment, by using the screwdriver, within the allowable turning range, without using excessive force.
Do an operational check with screws loaded in the scooping chamber and the timer set properly.
Check and adjust the brush
Load the screws into the scooping chamber, turn ON and OFF the power switch so that screws are alligned into the rail groove
Turn the power switch ON and then turn it OFF when the brush is in horizontal position with the screws facing up.
Check that the heads of the screws, in the rail groove, are in slight contact with the brush bristles. If the brush height is too high or low, this will have an adverse effect on the screw allignment and transport.
If any adjustment is necessary, loosen the brush height adjusting screw to adjust the brush height.
If the plastic portion, at the front of the brush. comes into contact with the passing plate, loosen the brush assembly mounting screw and make an adjustment either backward or forward
Operate the machine to check that the brush operation is normal.
Check and adjust the position of the rail
Loosen the rail fixing screw and adjust the rail either backward or forward.
After adjustment, be sure to tighten the rail fixing screw.
If the rail position has been adjusted, the rail vibration may need re-adjustment.
Repair Instructions
