This user manual applies to the Kongskilde CPU (Com-

ponent Pickup Unit).

The target group for this manual are operators, (electri-

cal) installers as well as maintenance and service sta󰀨.

Description:

The Component Pickup Unit system is intended as an

extension of the CVL 700 unit itself, which makes it

possible to move small components, eg. from a con-

tainer in a warehouse and into a production line, in ap-

portioned quantities.

The CPU is designed to handle components ranging in

size from 10 to 50 mm in cross section, provided they

do not have a geometry that allows them to interlock, or

are particularly fragile. The CVL cannot handle liquids

or adhesive / damp components.

It is possible to control the performance of the con-

nected blower based on the current suction needs of

the CPU, by retrotting a MUC control - see section

"Accessories".

The system moves the components by evacating them

through a pipe / hose system. The pipe system consists

of steel pipes and exible hoses, with a diameter of

Ø100 mm.

The Component Pickup Unit system must not be used

in the food and pharmaceutical industry or in areas

where the ATEX directive is required.

The container containing the components to be moved

is emptied via a telescopic suction pipe which evacu-

ates the components up and through the suction string.

The telescopic suction pipe moves slowly through the

container, while swinging to the sides and back and

forth, removing layer after layer of components.

The container must measure a maximum of 1,2 x 1,2 x

1,8m. The container must not contain loose parts such

as cardboard discs or plastic foil that can be sucked to

the telescopic tube.

The air velocity in the suction string is measured and

regulated by regulation throttle EAR100-C. It is impor-

tant that the air velocity is kept constant and as low as

possible, to ensure that the components are not dam-

aged during transport.

The air velocity su󰀩cient to transport the components

of the piping system, is not large enough to absorb the

components from the container and into the telescopic

suction pipe. Therefore, the air velocity locally at the

"pickup" end of the suction pipe is increased. Boost air

velocity is measured and regulated by regulation throt-

tle EAR100-B.

The components are evacuated into the CVL via the

telescopic pipe and associated piping. At the top of the

CVL there is an ultrasonic sensor that detects when the

CVL is full of components (about 10 liters of compo-

nents), in combination wit the suction time setting in the

control unit. Then the top valve stops suction in the pipe

string, where after the bottom valve in the CVL opens

and empties the components. Top valve and bottom

valve in the CVL are driven by their own air cylinder.

When the CVL is full and the air ow stops in the pipe

system, the telescopic suction pipe must be raised a

distance corresponding to the component height, to en-

sure that the components in the vertical part of the suc-

tion pipe fall out and do not block the suction pipe. After

the airow has restarted, the telescopic suction pipe is

lowered back to its original position and continues to

remove layer after layer of components.

The control of the CPU is connected to the control of

the CVL, to the control of the control valves (EAR 100),

and to the blower control. The system is integrated and

controlled from the CPU's control.

Access to the CPU control setting is done through the

operator panel in the column. The operator panel can

be logged in either as Operator or Tech, and only Tech

has rights to change settings.

See possibly section "Startup" with associated dia-

grams in the CVL manual, which describes the follow-

ing 3 installation modes:

Diagram C (Continuous process) - Should compo-

nents be drawn, typically from a magazine, with dis-

charge when a preset level in the CVL is reached, this

mode of operation is used. After discharge, the process

is repeated. This operating mode can be equipped with

start / stop contact, whereby the CVL can be stopped

when eg. the magazine is emptied.

Diagram D (Transport to external container with

level sensor) - Should components be drawn, typi-

cally from a magazine, with discharge in a container

equipped with full- and empty sensor, this operating

mode is used. The full- and empty sensor controls the

CVL, and ensures, that there are always components

in the container. This operating mode can be equipped

with start / stop contact at the CPU, whereby the CVL

can be stopped when eg. the magazine is empty.

It is optional if the blower should be started and

stopped by the control, or run constantly. If case the

blower should be controlled by the CVL control, the

blower must be connected, see diagram D.

Diagram E (Apportioned volume process) - Should

the components be moved, typically from a magazine,

with discharge in metered volume, this mode of opera-

tion is used. The volume is determined by a certain

number of discharges in combination with the level in

the CVL. After discharge, the process is repeated.

This operating mode can be equipped with start / stop

contact at the CPU, whereby the CVL can be stopped

when eg. the magazine is empty. Additionally, this mode

of operation shall be equipped with a reset switch, that

can be activated by replacing eg. cardboard boxes un-

der the CVL.

Warning signs:

Warning signs with symbols without text are found on

the CVL. The meaning of the symbols is explained be-

low. If a warning label gets damaged, and is no longer

legible, it must be replaced. New labels are available in

the spare parts list.

Read the user manual carefully and

observe the warning texts in the

user manual and on the CVL.

Piping must not be removed while

the CVL is in operation. Wait until

compressed air and electricity has

been disconnected.

The CVL is equipped with a yellow mark around the

compressed air supply on the back console, as this

connection acts as an emergency stop.

Warning notes:

Avoid accidents by always following the safety instruc-

tions given in the user manual and on the safety signs

located on the CPU system.

The CPU may only be activated if the area around the

system is secured against access by uninstructed per-

sons.

The mounting of the unit must be as prescribed (see

section "Installation"), if not, stability is reduced, and

wear increased.

Ensure that all guards are intact and properly secured

during operation.

Always disconnect electricity and compressed air sup-

ply to the CPU/ CVL system before making any repairs,

maintenance or removal of blocked components. In

case the blockage is removed while air supply or elec-

tricity is connected, the cylinders can move, causing

serious injury.

Never put your hand into the unit´s inlet or outlet during

operation.

Make sure the service technician / operator has secure

access to repair and maintenance of the CVL. The

working area around the unit should be clear and trip

free when carrying out maintenance.

Make sure that there is adequate lighting when working

on the CVL unit.

In case of abnormal vibrations or noise, stop the unit

immediately and examine the cause. In case of doubt,

skilled assistance must be called in for repair and main-

tenance.

Do not operate the CPU without a container below the

telescopic pipe.

To avoid any personal contact with the moving valves,

pipes of minimum 850 mm length, (maximum Ø 200

mm) must be installed onto the inlet and outlet connec-

tions. These pipes must be installed with bolt clamps,

where tools are necessary for dismantling.

In case it is not possible to use minimum 850 mm

pipes, it must be ensured, that there within minimum

850 mm from the inlet and outlet, in all connections,

are used bolt clamps, where tools are necessary for

dismantling.

The reason for this is, that according to EU-directive

2006/42/EC (Machinery Directive), it is not allowed for

any unauthorized personnel to gain access to moving

/ dangerous parts. In case quick couplings are used,

unautorized personnel could dismantle the piping, and

gain access to moving parts.

The suction head of the Component Pickup Unit sys-

tem is equipped with slip clutches in both horizontal

directions of movement to prevent clamping between

the telescopic pipe / container and the column. These

Distance between bends

For maximum capacity, there should be a minimum

distance of 2 meters between changes in ow direction,

i.e. between each bend.

Insertion of bends

Never insert 2 bends straight after another, if they can

be replaced by one, as this can result in damage to

components and loss of capacity.

Assemblies and centring

All pipe joints must be tight and without any o󰀨set, as

these may damage the components!

When assembling pipes, bends and other material in-

tended for component transport, it is important to centre

the pipes as precisely as possible next to each other.

One cannot always expect the pipe to be centred by the

clamp alone. The quick clamp / bolt clamp is designed

so that it clamps the OK anges very hard to ensure

a tight assembly. This causes the friction between the

pipes to become so high that the clamp cannot centre

the pipes.

To check if the pipes are centred, one can check that

the distance between the clamp and the pipe is equal

on both sides of the clamp.

If you want a very tight joint, you can wrap the joint with

sealing tape before the clamp is applied.

Kongskilde recommends the use of the KCP 100R

pipe system, which ensures proper centering and

sealing of piping, which eventually reduces the risk

of component damage.

The 2 meter pipe is delivered with a loose ange on

the outlet side (not welded on), and can therefore be

used when adjusting the length, like a xed telescopic

pipe. The ange must be TIG welded, with concentricity

requirements as shown at the back in the manual, and

subsequently pickled.

The Component Pickup Unit system must be installed

indoors, at ambient temperature between 0° and 50° C.

Mounting:

The Component Pickup Unit system must be installed

on a stable, at concrete surface. The column must be

attached to the oor with expansion bolts, according

to the regulations from the bolt supplier. The enclosed

footplate must be mounted at the bottom of the column

as shown, to protect the column from damage caused

by truck collision during replacement of container, oc-

tabine or vacuum box.

It may also be necessary to mark with yellow / black

marking on the oor, or make other shielding. See sec-

tion "Warning notes".

Footplate

The piping and boost air / suction air hoses must be

securely supported to prevent breakage and leaks. The

suction hose should be controlled with a min. 300 mm

bending radius to prevent the components from block-

ing the hose.

Both the boost air- and conveying hose must be kept

as short as possible to reduce energy consumption, the

risk of static electricity, and component damage.

Kongskilde o󰀨ers matching hoses and pipes, see sec-

tion "Accessories".

All pipelines and hoses must be installed before con-

necting electricity to avoid personal injury.

The CPU's control is delivered mounted in the upper

half of the CPU column upon delivery. If the control is

desired to be located in the lower half of the column,

the control can be hooked o󰀨 the mounting tabs and

moved. To access the control, the CPU backplates

must be removed. The control is supplied with the re-

quired extra cable length.

Kongskilde recommends using stainless steel pipes for

component transport, as this will facilitate cleaning and

minimize contamination to the components. In addition,

it may be necessary to ground the installation and pos-

sibly install anti-static equipment to avoid static electric-

ity that can lead to component clumping and fouling.

See section "Electrical Installation".

External communication with e.g. Siemens PLC

If integration is made between the CPU control and

an external PLC control, the warranty on the control is

void.

During installation, the CPU can be lifted with a strap

in the two holes at the shaft of the suction head and

around the shaft on the coloumn.

Accessories

Kongskilde o󰀨ers the following accessories for the

Component Pickup Unit system - for more information,

please contact Kongskilde.

Conveying- and boost air hoses and Kongskilde

Component Piping KCP 100R (accessory)

Kongskilde o󰀨ers conveying air hoses in 2,5 and 20

meters length, boost air hose in 2,5 meters length, as

well as various clamps and transitions.

In addition, piping in Ø100mm stainless steel (KPC

100R) is available for component transport. See back

of the manual.

External start / stop and telescopic pipe up / down

switch (accessory)

The CPU system can be equipped with an external

start / stop and telescopic pipe up / down switch. This

can be used if the operator panel is not mounted opti-

mally to the operation of the CPU system. The external

switch is equipped with a 10 meter cable that can be

extended to 100 meters, and should be connected to

the CPU control.

Blower control (Multi Unit Control)

It is possible to control the blower performance from

the CPU's current suction needs, by retrotting a MUC

control. The controller is mounted internally in a MultiAir

FC blower, and connected to the CPU's control with a

6-wire cable. Installation instructions and connection

are shown in the enclosed guide.

A MultiAir FC1250 blower will be able to drive up to 6

CPU´s.

Electrical connection:

The Component Pickup Unit system control is connect-

ed to L, N and ground via the supply cable (min. 3x1.5

mm2- not included), which is relieved at the bottom of

the column.

If an HPFI residual current relay is required on the pow-

er supply to the CPU, it must be a 300mA type B relay,

since the control contains built-in AC drives.

Blower control (Multi Unit Control)

The MUC controller is mounted internally in the MultiAir

FC blower, and connected as follows (see the enclosed

guide):

Start (hold switch) is connected to terminals 9 and 10.

Rpm Up are connected to terminals 11 and 12.

Rpm Down are connected to terminals 13 and 14.

Potential equalizing

In order to avoid the build-up of static electricity on

the components and reduce the possibility of static

discharges when the Component Pickup Unit system

is touched, it is important that the suction hose (Ø100

mm) ground conductor is properly connected to the

spigot at the top of the suction head and on the CVL.

Emergency stop

The Component Pickup Unit system pillar is equipped

with emergency stop, activated by pressure, and reset

by turning the emergency stop.

When planning the complete system, it should be deter-

mined whether any overall emergency stop contact is

necessary. If this is chosen, the general / local require-

ments for such contact must be met.

The emergency stop must disconnect the compressed

air supply and vent the cylinders on the CVL as this is

the only way to open both cylinders.

The requirements of the local Labour Inspectorate must

also be met.

Electronic Air Regulation (regulation throttle for

boost- and suction air)

The regulation throttle control box is connected to the

CPU's control with a CAT6 data cable. The data ca-

ble is plugged inside the EAR control box and guided

through the CPU column at the cable relief in the bot-

tom. Do not extend the cable as joints may impair reli-

ability.

External start / stop and telescopic pipe up / down

switch (accessory)

See section "Accessories".

Startup:

The parameters in the control unit can be adjusted to

ensure optimal integration of the complete transport

system. During balancing, it is recommended to pay

special attention to the air velocity of the system, as too

high a velocity may damage the components.

Before starting, check the following:

• that there are no foreign bodies in the Component

Pickup Unit, the CVL, the associated pipe system

or any suction hose

• that the compressed air supply is within the speci-

ed values

• that all connections to the control unit are properly

made

• that all parts are securely attached, including pipes

and any suction hose

• that the component output on the CVL is placed

min. 2,7 meters above oor level, to prevent ac-

cidental access to the bottom valve of the CVL,

which could otherwise result in personal injury

• that a container (with a max. width of 1.200mm,

a max. depth of 1.200mm and a max. height of

1.800mm) is located under the telescopic pipe. The

bottom of the container must be min. 150mm above

oor level

Component setting is changed by selecting a component number and conrm with Component settings con-

rm, where after the Component name eld is changed to show the current component.

The above are the only values that can be changed by User Operator. The following values for the component can

be changed individually, but only by user Tech. All times are given in milliseconds (ms) and all lengths in mm.

• Container low level setting adjusts when the info Low level appears, relative to the bottom of the container. A

distance of approx. 200mm is recommended.

• V1 Conveying speed setting adjusts the system suction velocity, in m/s. This value should be set as low as

possible to avoid damage to the components. In general, do not convey the components faster than what the

desired capacity allows and what is needed. As a starting point, one can hold a container of components up

to the telescopic pipe and check if the components are e󰀨ectively sucked up. Subsequently, the suction veloc-

ity can be lowered until there is no longer e󰀨ective suction, and then increased by e.g. 1- 2 m/s. In addition,

the blower speed should be adjusted according to the transport length and the components transported, etc.

Always adjust to the lowest required air velocity, to ensure as gentle transport as possible, and to reduce noise

and energy consumption. NB - Kongskilde o󰀨ers a control (Multi Unit Control) that allows the CPU to control

the performance of e.g. a MultiAir FC blower,see section "Accessories".

• V2 Pickup speed setting adjusts the combination of boost air and suction air velocity. This value thus indi-

cates V1 suction air velocity + boost air velocity, and should basically be twice the V1 Conveying speed. If V2 is

set too high, the components are sucked to the bottom perforated part of the telescopic pipe.

• Distance from bottom setting adjusts the height as the telescopic pipe moves upward after detecting the bot-

tom level of the container. Should be set to the average height of a component.

• Distance between layers adjusts the distance between each layer of components in the container, and should

be adjusted to the geometry of the components. The value is the distance the telescope pipe dives between

each layer of components.

• Number of nal sweeps setting adjusts the number of times the telescopic pipe swings back and forth after

reaching the bottom position. Should initially be set to 2, but can be increased if a satisfactory emptying of the

container is not achieved, after correct setting of V1, V2 and Distance from bottom. The number must be at

least 1.

• The telescope setpoint setting adjusts the height of the telescopic pipe above the oor and should at least

allow the container to be placed without hitting the telescope pipe. The distance is set by logging in as a Tech

user, going into the Component Pickup Unit settings display menu, lowering the telescopic pipe to an appropri-

ate height, and reading the value. The value can then be entered under the Telescope setpoint..

• Number of CVL shakes adjusts the number of movements in the bottom valve. This is done by rst opening

the cone in the bottom valve completely, and then closing approx. 4 cm, to shake o󰀨 any hanging components.

The movement takes a few tenths of a second, and is done 3 seconds after opening the bottom valve. The

number of movements should be set as low as possible, but should still ensure that there are no components

hanging around the bottom valve cone.

• CVL emptying time setting adjusts the time from the CVL bottom valve opens until the bottom valve closes.

Should be set as low as possible, but not lower than all components manages to fall out of the bottom valve. If

not all components have fallen out, a rattle from the CVL will still appear and the time must be increased.

• Languages can be selected between English, German, French, Polish and Danish.

• Safety Stop can be used for external PLC communication, as a stop when, for example, a safety cage is

opened, and the safety circuit should be disconnected. If set to active, it does the following:

1. Stops the program

2. Stops the telescope in its current position

3. Stops CVL and connected blower after 10 seconds

• Electronic Air Regulation can be switched between single and double. If the CVL is placed at a longer dis-

tance from the CPU, it may be advantageous to use a smaller blower to generate boost air. The boost air regu-

lator throttle will be placed close to the CPU and therefore requires an additional control unit. In this case, sin-

gle (standing) control must be selected. If the CPU and CVL are placed close to each other, the blower gener-

ating suction air will usually also generate boost air, and both control throttles can therefore be controlled by the

same control unit. Here, double control is selected (the setting is given in advance when planning the project).

• Local / remote control start / stop is selected, depending on whether the CPU system should be started and

input from the operator´s panel. If Remote is selected, the control will only accept input from the external start /

stop switch.

• Local / remote control up / down is selected, depending on whether the telescope pipe is to be raised and

lowered at the CPU (on the operator´s panel in the column), or on the external up / down switch that will nor-

jammed components.

An automatic circuit breaker is installed in the control to

protect the power supply to the PLC unit. If the circuit

breaker disconnects, the cause of this must be investi-

gated before reconnecting.

Service and maintenance:

All service, maintenance and repair must be performed

by qualied or trained personnel.

Always turn o󰀨 the power to the CPU before inspection,

and be sure to lock the main switch if desired, so that

the CPU cannot be started by mistake.

During cleaning or other service of the CVL, the com-

pressed air is switched o󰀨, and at least one sequence

is run, after which the power is switched o󰀨, e.g. on the

control main switch. The main switch can be locked if

desired.

The suction head contains couplings on the 2 gear mo-

tors, which control the forward / backward and side to

side movement of the telescope pipe.

The gear units on the gear motors are lled with syn-

thetic oil from the factory, which does not require re-

placement.

Pay attention to leaky oil seals.

If the telescopic pipe has di󰀩culty moving into the outer

positions, it may be necessary to tighten the couplings.

If the telescopic pipe pushes too strongly against the

sides of the container, it may be necessary to loosen

the couplings - the pipe must be able to be pushed

sideways by hand. In both cases, the adjustment re-

quires a special key as shown below.

Operation:

Start

• Container with components is placed under the

telescopic pipe. The foot plate of the CPU's column

can be used as a stop for the container.

• The blower / CVL and other associated machinery

are started, and the CPU main switch turned on.

• The CPU system starts and the Start icon changes

to green.

• When the yellow arrow appears on the operator´s

panel, the telescopic pipe can be lowered manu-

ally until the surface of the components. Be aware

of the height of the components in the box be-

fore emptying is initiated. If the suction end is not

lowered enough, the telescope swings beyond

the box edge! Advantageously, the surface of the

components can be levelled out before starting, to

increase the e󰀩ciency of the emptying.

When emptying is complete, the telescopic pipe returns

to its original position and a new lled container can be

placed under the telescopic pipe, after which the pro-

cess can be repeated.

Pause

If desired, the CPU system can be paused, whereby

the Pause icon changes to blue. The system is restart-

ed by pressing Start.

Stop

If desired, the CPU system can be stopped, by press-

ing the Stop icon. The system is restarted by pressing

Start. At Start after Stop, the program starts all over

again.

The Low level icon appears as a reminder, that the tel-

escopic pipe is approaching the bottom of the container

(as a starting point approximately 200mm above the

bottom of the container).

The Prepare new container icon appears, as the tel-

escopic pipe begins emptying the last layer of compo-

nents in the container.

In case of clogging of the telescopic pipe, the pipe /

hose system must be dismantled and emptied / cleaned

manually. This can usually be done by removing the

suction hose at the top of the suction head and pulling

the blocked components up into a bucket or similar.

When switching from one type of component to anoth-

er, it is important to completely empty the CPU system.

This is usually done by running a pair of sequences

without components to empty the CVL's interior.

In some circumstances, it may be necessary to open

The couplings are adjusted as follows:

Gear in suction head

1. Turn o󰀨 the power to the CPU and stop the blower.

2. Remove the left cover on the suction head (seen

from front).

3. Tighten the coupling by turning the coupling ring

clockwise.

4. Loosen the coupling by turning the coupling ring

anticlockwise.

5. Check the operation of the telescopic pipe.

6. Attach the cover on the suction head.

Gear in column

1. Turn o󰀨 the power to the CPU and stop the blower.

2. Remove the upper back plate on the column.

3. Tighten the couplings by turning the coupling ring

clockwise.

4. Loosen the couplings by turning the coupling ring

anticlockwise.

5. Check the operation of the telescopic pipe.

6. Attach the back plate on the column.

The CPU does not contain any parts that require spe-

cial service or maintenance, but can be cleaned on

outer surfaces if needed. Furthermore, it may be nec-

essary to wipe the telescopic pipe, by fully extending it,

and wipe it with a suitable detergent.

The traction required for the CPU to slip in the clutch

is 10 kg when telescopic pipe is fully raised, and 6 kg

when it is fully lowered.
