2 Safety
It is important that the following safety precautions are observed:
Only trained and authorised operators shall use this equipment. Contact Atlas
Copco IAS or an approved engineer for help if you are in any doubt of your
ability to operate or maintain the equipment.
With Compact Bulk Rivet Feeder systems, the rivets can travel through the
T-Tube at very high speed. Do not operate the system without the end of
the T-Tube being restrained and with the intended equipment or a suitable
container in place.
Ear protection should be worn if operating the Compact Bulk Rivet Feeder with
the lid open, as noise levels can be high.
Always wear approved safety glasses when operating the equipment with the
lid open. Other PPE may be required for various operations and maintenance
tasks.
Refer to the manuals for the other Self Pierce Riveting System components
for safety precautions relating specically to these items - Tool, Selector, Die
Changer and Controller.
Follow safe lifting/handling guidelines if moving the Compact Bulk Rivet
Feeder.
Do not t worn or broken parts to the Compact Bulk Rivet Feeder.
While every eort has been made to ensure this equipment is safe, a
comprehensive assessment is not possible before the equipment is installed and
commissioned in its ultimate environment. It is therefore, responsibility of the
end user of this equipment, to conduct a nal risk assessment of the equipment
when installed and to implement any additional preventative measures.

assembly.
Fitted under the cover is a plate assembly which houses the control modular I/O system
(BL20) which incorporates the digital input and output modules and electrical terminal
blocks.
The plate assembly seals the top of the unit and prevents stray rivets from entering the unit.
The cover is secured to brackets on the plate assembly by four cap screws tted with hole
plugs. The top cover will need to be slid rearwards to separate the top cover and plate
assembly.

The hopper assembly is located under the plate assembly and there is a cut-out in the plate
for the rivets to enter the hopper chute.
The hopper chute is angled to feed the rivets to the dispensing section of the hopper and
stopped by a bae. The rivets are collected onto the dispensing platform ready for controlled
transfer to the bowl.
The dispenser unit is agitated by a pneumatic cylinder and piston located under the chute for
a xed period and is triggered by the bowl low level sensor.
CAUTION
Always check that the rivet type and size is correct before adding rivets
to the hopper.
Do not ll the bowl directly. Only ll via the hopper

8 - Bowl full sensor
9 - Rivet
The Vibrating Bowl
aligns the loose
rivets ready to feed
down the track to the
escapement.
The escapement track
sensor detects the
presence of rivets in the
track. When no rivets
are detected the bowl is
activated.
The vibrating bowl runs
until rivets are again
detected by the track
sensor.
The bowl consists of spiral tracks that convey the rivets from the base of the bowl to the slot
in the exit section of the bowl. The exit section of the bowl is covered where the rivets enter
the track. This is to prevent stray or rivets from entering the escapement.
An inductive sensor tted above the track will identify when the track is full of rivets and
stop the bowl vibrating. These airline help the orientation of rivets entering the track (radial
blows) and prevent blockages in the track (recovery blow).
Fitted underneath the base section of the bowl is an inductive sensor which is the bowl full
sensor. When the bowl is low of rivets the hopper dispenser is agitated to replenish the bowl
with rivets.
CAUTION
Each Compact Bulk Rivet Feeder is programmed to work with a specic
rivet. Caution should be exercised to ensure that only the correct rivet is
loaded. The part number is on the rivet pack and this should match the
rivet type for the machine.

11 - Rivet
The escapement takes a
single rivet and presents
it in front of the T-Tube
from where it is blown
along the T-Tube to the
Magazine Stand, Tool
or Selector System. The
rivet exit sensor detects
that the rivet has left
the gate and entered
the T-Tube. The gate
position sensors detect
that the gate cylinder is
in the correct position
to feed the rivet along
the T-Tube.
The rivets from the bowl are fed serially down a vertical chute to the gate. The gate is
actuated by a double acting cylinder, the rst rivet in the escapement rests against the edge
of the gate, the cylinder is actuated and the rivet falls in a slot in the gate, the gate is retracted
and the rivet falls into the main blow section where the T-Tube is tted. A clear plastic window
allows in front of the gate allows visual viewing of the gate action and the transfer of rivets.
A micro-switch tted to the escapement cylinder detects it at the retracted position. The
escapement cylinder is actuated by a pneumatic solenoid valve. The clamp post has an
eccentric mounting so can be rotated to adjust the alignment of the escapement and then
slid forwards/back in a slot. The escapement height it adjusted using the knob on the
escapement.
WARNING
The escapement gate moves quickly when actuated and may create a
trapping point. Do not operate the equipment with the escapement
clear cover removed.

7 - Base panel
The pneumatic
vibration unit and
bowl spring are
mounted on a bracket
on the underside of
the bowl. There are
three additional bowl
springs mounted to the
underside brackets of
the bowl.
Each spring is secured
to the bowl base plate.
The base plate is tted
with four rubber spring
mounts that prevent
vibration resonating
throughout the unit.
The vibration unit is a pneumatic piston vibrator. The vibration will increase as the pressure
increases. An in-line regulator adjusts the pressure and hence vibration frequency of the Bowl.
During installation the vibration frequency is adjusted to match the rivet size and type.
The vibration unit regulator can be adjusted to optimise rivet ow.
CAUTION
A poorly set vibratory unit can seriously impact rivet feed reliability.
The vibration intensity setting however, should be individually
established and match-marked for each Bulk Feeder

4. 7 Standard Control Module
The control module is located under the cover
and tted to a rail on the plate assembly.
It consists of a programmable PLC with an
associated digital input card for the sensors
and digital output card for the solenoid
valves and prime track button. There is also a
terminal blocks for the associated electrical
wiring. The programmable PLC has two
Ethernet ports which connect to the bulk
plate at the rear of the unit.
It needs to receive signals from a Unity panel
or Robot Controller to feed rivets to any other
piece of equipment.
Communication between the Controller and Bulk Rivet Feeder is made via the control module
using Ethernet.
Each Compact Bulk Rivet Feeder system BL20 module is assigned a unique node address
which is set by dials on the unit.

NOTE
This lter is a particulate lter. The customer needs to ensure their air
inlet to the unit is free from contaminants such as oil and water.
