develop these into useful production support.

VERSAtILItY tOdAYS KEYwORd

The trends among designers and architects are touse a large variety of different concrete products

in the Landscaping process. This gives the produ-

cers an extra challenge as they have to develop the

mould and the production process to suit.

To make this process protable it is necessary to

have a very versatile production machine. This

scenario has been a fact for the Danish concrete

producers for several years due to the fact that their

consumer volume is in the low end.

For this reason a KVM block machine is con-

structed to operate protably, making high class

output, with a large variety of products even pro-ducts not normally seen made on a block machine.

BLOCK MAKInGMACHInEThe heart of all block and paving producing facto-

ries is the blockmachine. KVM blockmachines can

produce all shapes and sizes from large slabs 1m by1,2m to kerbstones, blocks and pavers. The smallest

28mm thick pool slabs to the largest 600 kg retai-

ning wall blocks - all on the same machine and all

with exactly the same high quality.

MACHInE pROGRAMMEKVM International manufactures three different

series of Block Making Machines. Depending on

the customers needs and demands large or small

production capacities KVM will guide the custo-

mer in the direction of the most suitable blockma-

chine.

Series I: Type 62/80, pallet size 750 x 900mm

Series II: Types 62/105, 90/105 and 62/125,

pallet size up to 750 x 1400mm

Series III: Types 80/125, 105/125 and 125/125,

pallet size up to 1300 x 1450mm

All types of blockmachines use the well known

KVM controlled concrete handling system ensu-

ring that every kilo of concrete delivered into the

mould is handled in exactly the same way.

The controlled concrete handling is based on the

following features:

Transport of concrete to the silo on the

blockmachine is done with a slow moving belt

conveyor that delivers concrete in the same rate

as it is being used. This gives the same weight

and density of the concrete all the time

A cone shaped rubber sock in the silo guaran-

tees against segregation of the concrete The silo is lowered into the lling box each

cycle to ensure that only the needed amount of

concrete is delivered

The lling box has no internally moving parts

making it possible to empty it after each cycle

The tuning vibrator allows for adjustment of

both amplitude and frequency during both the

lling and the compaction part of the produc-

tion cycle

All movements are controlled by the advanced pro-

portionally controlled hydraulic system. The easy-

to-operate control system enables the operator to

quickly implement changes and to adjust to chan-

ges in materials and products.

KVM blockmachines are delivered with the follo-

wing standard features:

The blockmachine is placed on rubber dampers

under the machine frame which minimises the

need for foundation work and reduces the

vibrations transmitted to the surroundings

High efciency motors and a special energy

saving hydraulic system reduces the environ-mental impact.

HAndLInG SYStEMAll KVM handling systems are designed to be fa-

ster than the blockmachine at all times and have

built in buffers to enable the system to avoid small

stops giving delays for the blockmachine.

tRAnSpORt wEt SIdETransport from the blockmachine to the elevator

is done by roller or v-belt conveyors that ensure a

gentle transport of the wet products. The wet side

conveyor is divided into several individual sections

that allow the conveyor to work as a buffer zone.

OptIOnS FOR wEt SIdEThe wet side can be equipped with additional optio-

nal equipment:

QUALItY COntROL

Weight, height and density can be controlled and

the information can be presented to the operator

and it can be used to either manually or automati-

cally adjust the settings on the blockmachine;

A laser based height measurement unit controlsthe height of the product

A weight measuring unit weighs the products

An ofine control position allows for detailed

measurements while the production continues

SCRAp EjECtOR

To scrap the waste from cleaning or reject bad prod-

ucts the control position can include a function to

tilt the materials into a skip. Afterwards the empty

pallet will automatically return to the wet side con-

veyor system.


5/12

HAndLInG SYStEMThe size and shape of the handling system is de-

cided by and adapted to the needs and demands

from the customer based on product portfolio, site

layout, climate, capacity, existing buildings etc.

ELEVAtOR And LOwERAtORKVM elevators and lowerators are as a standard of a

double pallet conguration ensuring that the hand-

ling system always works faster than the blockma-

chine and cubing units, whether it is working with

28mm slabs on every shelf or 500mm high chimney

elements on every third.

The elevators and lowerators can be tted with ac-

tive or passive buffers that reduce the risk of delays

caused by different cycle time on wet and dry sides.The elevators can be equipped with service plat-

form and automatic lubrication of the chains.

RACK SYStEMThe racks are designed according to the demands of

the customers product programme regarding shelf

distance, load bearing capability, steel type etc.

Racks can be made in Zinc-coated or stainless steel

materials or a combination of both.

The racks can be left open or insulated in indivi-

dual sections with automatic roller doors or as one

closed big chamber solution that also includes the

elevator, the nger car and the lowerator. The cu-

ring climate can be controlled and improved by air

circulating and ventilation systems adapted to the

demands of the customer. Advanced climate con-

trol units can enhance the curing climate by adding

active gasses or preheated moisturised air to the

curing area.

FInGERCARA heavy duty ngercar transports the products from

the elevator to the racks and back to the lowerator.

The ngercar is controlled by lasers and is driven

by servo units for fast and precise movements. The

ngercar can be equipped with turn table and with

displaceable forks for high and low products.

tRAnSpORt dRY SIdERoller conveyors handle the transport of cured

concrete products from the lowerator to the cubing

position. The dry side conveyor is divided into in-

dividual sections that allow the conveyor to work as

a buffer zone.

OptIOnS FOR dRY SIdEThe dry side can be equipped with additional optio-

nal equipment:

Quality control zone where the operator can

remove rejects safely while the rest of the dry

side conveyor system continues without delays

In-line splitting unit

Prepress unit for loosening products

Doubling unit for delivering 2 layers at the

time to the cuber Scrap ejector for removing rejects

Production board de-doubling unit

HAndLInG OF EMptY

pROdUCtIOn BOARdSAt the end of the dry side conveyor the pallet return

system cleans, oils, turns, stacks and accumulates

the production pallets before sending them back to

the blockmachine.

The pallet return system comes in several variations

depending on the need to accumulate empty pallets:

Single pallet return on roller conveyors with up

to 10 pallets between cuber and blockmachine

A transfer car system that accumulates

approx. 100 pallets and allows for easy fork lift

access to the area between the blockmachine

and cuber

An additional transfer car buffer with up to1000 pallets

A traditional crane unit stacking up to 4000

pallets in a buffer


8/12

CUBInGKVM cubers are constructed for maximum versati-

lity and can handle all the products produced on a

blockmachine with high speed and precision. The

clamp is encoder controlled and driven by a high

power hydraulic unit. The drive unit is by a toot-hed belt drive and the cuber has an elevated service

platform and ladder for safe and easy service.

Product formatting units are used to reshape the

product format to t special types of transport pal-

lets or to build void packs with holes for forklift

ngers.

As an option a vacuum lifting device can be instal-

led to handle special products.

ROBOtICS

For special jobs standard industrial robots with

special grippers can be utilized.

CUBEd pROdUCt tRAnSpORtProducts can be delivered with or without transport

pallets. Depending on the demands of the customer

the following types are used;

Chain conveyor

Roller conveyor Slat conveyor

Steel pallet circulation systems

Depending on the local requirements, stacks can

be strapped or wrapped. KVM offers several dif-

ferent types of packing;

Plastic wrapping

Horizontal strapping

Vertical strapping

Stretch hood

Shrink wrapping

KVM SpLIttInG SYStEMKVM manufactures complete splitting systems.

The splitting unit is capable of both I and Y split-

ting of products of up to 1200 mm.

Splitting lines can be installed as in-line units ca-pable of keeping up with the rest of the blockplant

and as stand alone off-line systems.

The splitting line can be joined to a tumbling line

making it possible to tumble the split products gi-

ving a unique nish.

wASHInG SYStEMThe KVM washing unit is integrated into the wet

side line on the blockplant.

The unit washes the surfaces with an adjustable

high pressure water spray. The products are then

cleaned by water owing over the surface and -

nally dried with a high speed air fan.

InSULAtIOn ELEMEntS

- ISO LInE 2000In order to preserve the global climate the insula-

tion standards world wide are sharpening the de -

mands for walls and foundations in houses.

KVM has developed a process where two standard

building blocks are made into a sandwich block

with insulation inside.

This process has several advantages;

Different inner and outer block materials

Different type and dimension of insulation

materials

Different types of adhesives can be used

Easy change in block dimensions

The ready made insulated blocks greatly reducethe workload on the construction site.
