Long line

It allows the decoiling of most coils, with the highestrates and the longest feed lengths. To improve safetyand reduce the production changeover times, it isoften complemented by strip introduction assistanceaccessories. By adding a second loop between thedecoiler and the straightener, the long line can beadapted for decoiling the most delicate materials.

SHORT "3 IN 1" LOOPLESS LINEConsisting of a decoiler and a MICROPRO®

straightener-feeder, possibly mounted on a commonbase, it is reserved for medium feed rates andlengths. It is often the most economical solution forthe manufacturer.It leads to a saving in occupied area of 40 to 50%.The loop pit is not necessary. It is not suitable fordelicate materials. The coil weight is generally limi-ted to 6500 kg.

REAR LOOP "SHORT LINE"This high performance confi guration is the mostsuitable one for heavy section or high yield strengthmaterials for which high press rates and feedlengths are nevertheless required (automobile in-dustry for example).It leads to a saving in occupied area of 40%, wi-thout loop pit. The safety of the operators is gua-ranteed by the fully automated strip introductionand loop forming.

CUT-TO-LENGTH LINESThe DIMECO cut-to-length lines are mainly inten-ded for service centres of medium size and for ma-nufacturers wishing to have their blank cuttingactivity internally in order to improve their com-petitiveness and adaptability.They offer an exceptional price for value. Depen-ding on the required rates and the materials beingcut, one of the decoiling line architectures descri-bed above will be chosen. The integrated shearcan be pneumatic, mechanical or hydraulic.The stacking can be single pile or multi-pile andperformed by a fl ap type, a programmable Car-tesian or a robotic stacker.A fi lm application or removal device can be in-cluded in the line.

T H E D E C O I L E R S

DIMECO offer a full range of decoilers for coils of50 kg to 25 tonnes. The range of widths is from 10mm to 2000 mm.The permissible coil diameter can be up to 2100mm on the largest models.

LONG LIFEThe durability of the DIMECO mandrels is widelyrecognised. They consist of parts machined fromcastings. The guidance is provided by bearingsdesigned to last for more than 15 years. For loadsof under 3 tonnes we use sealed ball bearings.Above this fi gure, roller bearings are preferred. The DIMECO 3-jaw design allows coil loadingwith sling or hook. It facilitates the strap removaland strapping operations. Each of the jaws isequipped with a ruler allowing easy centring ofthe coil on the mandrel. The expansion can be ma-nual or hydraulic.

Long consideredas a rudimentary machine,the decoiler has nowadaysbecome a key productivityelement of the automated

cutting line.

LINK TYPE EXPANSIONFor decoilers of up to 6.5 tonnes, low backlash linktype expansion kinematics have been chosen. Theabsence of backlash allows very precise coil ali-gnment under all circumstances.

RAMP TYPE EXPANSION For heavy decoilers, the traditional kinematics arereplaced by a generously dimensioned ramp me-chanism. The jaws are then machined in combform in order to prevent end-ofcoil decoiling inci-dents.

CAREFUL FINISHMaintenance is reduced to a minimum. The fragilecomponents (electrical, pneumatic and hydraulic)are located inside the base for better protection.The movements are operated by a robust and er-gonomic remote control.

Our decoilers allow the coil to be decoiled fromunderneath, from above, from the rear and evenwith no loop.

SINGLE DECOILERS FOR ONE COIL8 machines cover a range of coils from 50 kg to25 tonnes.Depending on the material being decoiled and thelayout of the line, the decoiler can be equippedwith a pneumatic safety brake or a mandrel rota-tion drive.The drive is then powered by a hydraulic motor oran asynchronous motor piloted by a frequency in-verter. It considerably assists the introduction andrecoiling of the strip.

DECOILERS FOR SEVERAL COILSThis version is essential for fast production chan-geovers. It allows the coil to be changed in com-plete safety while the line is still running.Our range of 6 double decoilers covers a range ofcoils from 50 kg to 6500 kg.The turret rotation can be manual or hydraulic.

Decoilers for 3, 4 or 6 coils can also be offered asspecial builds.

HORIZONTAL DECOILERSReserved for coils of up to 1800 kg and with amaximum diameter of 1300 mm, they are parti-cularly suitable for the decoiling of thin strips anddelicate materials. The pallet loaded with severalstacked narrow coils can be directly installed onthe decoiler.

THE "COMBINED"DECOILER-STRAIGHTENER CRADLEWith a standard capacity limited to 5000 kg, itcombines in a single frame the strip decoiling andstraightening functions. It can be easily movedfrom one press to another. Simple and economical,this product is well suited to the decoiling of thickand narrow strips, used for example on fi ne blan-king lines.

Coil-car with powered rolls

Always listening to their customers, DIMECO havedeveloped a wide range of accessories designedto improve the productivity and fl exibility of theline and the safety of the operators.

FOR ALL MATERIALSDIMECO decoilers can be equipped with devicessuitable for working with high yield strength metalsor decoiling delicate materials (pre-lacquered,copper, polished aluminium...).

SAFETY IMPROVEMENTKeeping the coil under tension during the decoi-ling, strip introduction and strapping operations isessential for the safety of the personnel.To ensure this essential function with strips morethan 3 mm thick, DIMECO offer a wide range ofsafety pressure arms: pneumatic (BP) or hydraulic(BPH) arms, motor-driven roller arms.On the double decoilers, a pressure arm must beinstalled on each mandrel to allow coil changeo-ver while the line is running.

Bras presseur hydraulique motorisé,bras anti-foisonnement

For heavy gauge or high yield strength strip, theaction of the pressure arm must be complementedby 2 extra pressure arms (BAF) situated at 120°.The lateral coil keepers (GLAT) allow any acciden-tal decoiling of the strip to be avoided, assist stripintroduction into the straightener and contribute tothe easy recoiling of the strip.On the basic models, the keepers are mountedand adjusted manually on the jaws of the mandrelby the operator. For the heavier decoiler models,the tapered reinforced coil keepers (GLI) are loca-ted on a separate frame.The distance between the retractable guides is ad-justable and possibly programmable.

TILTMATIC®

SIMPLFYING THE TASKS OF THE OPERATORSAll the DIMECO decoilers can be equipped, wi-thout civil engineering work, with a coilcar (ETC)with an elevation stroke of 500 or 700 mm.Controlled by a hydraulic cylinder, the ETC allowseasy introduction of the coil on the mandrel. Thecoil can be simply and safely loaded onto theequipment with a fork-lift truck.The ETC can be equipped with motor driven rol-lers (RXM) to allow loop formation in the "rearloop" configurations.The movable decoiler option (TSR), combined witha fixed coil elevator, offers the operator incompa-rable comfort. The mobile decoiler loads the coilas far as it will go onto the mandrel. The decoileris then lined up in its working position thanks toan electrical control. The retractable coil keepers(GLI1) tilts to guide the coil as closely as possible.The transverse position of the decoiler can also beadjusted during production to accommodate, forexample, poor wound coils.In the (TSR) confi guration, the fi xed loading ele-vator can be replaced by a MULTICOIL systemconsisting of several mobile carts perpendicular tothe decoiler mandrel, each cart receiving a coil.The operator has the coils available which he mustuse during his work shift.

A WORLD EXCLUSIVE: THE TILTMATIC®

Coils of thin strip, delivered flat, can be directlyplaced on the platform of the TILTMATIC® devicewhich automatically takes care of the tilting andloading of the coil onto the decoiler.

IMPROVING PRODUCTIVITYThe PITSTOP® confi guration allows the introduc-tion and recoiling of the strip without manual in-tervention and offers automatic adjustment of allthe machine parameters when selecting the partfrom the production list menu.When coupled to a straightener and a DIMECOfeeder, the speed of a DIMECO decoiler is auto-matically adapted to the press rate and to the feedflow-rate.

T H E S T R A I G H T E N E R S

The choice of the model of straightener is the resultof a complex compromise between the extent ofthe required range of operation (metal thick-nesses...), the intended flatness and the cost of theequipment.This is why DIMECO have developed a range ofover 80 straighteners to deal with the various pro-blems of manufacturers, for strips 0.05 mm to 10mm thick, with widths up to 2000 mm and sectionsof up to 8000 mm².The maximum straightening speed is up to 50m/min as standard.

GEOMETRYThe geometry of the equipment, particularly theparallelism of the rolls, is vital in order to achieveoptimum straightening. Our frames, built from ironcastings, are machined on precision machiningcentres. The rolls are guided by low backlashneedle bearings and immobilised transversely byneedle thrust bearings or ball bearings.

HI-SPEC ROLLSSpecial care is given to the production of the rol-lers, which are case-hardened, ground and truedto guarantee maximum impact toughness andhardness of 60 HRC at a depth of 1.5 mm.

The choice of straighteneris the trickiest stage

in the definitionof a decoiling line.

The precise identificationof the range of materials

to be straightenedand of the intendeddegree of fl atnesswill allow the key

construction parametersto be chosen: number, diameter

and coating ofthe rollers,system of adjustment...

SUITABLE MOTOR-DRIVESThe maximum power actually transmitted to thestrip determines the straightener’s performance. Allour straighteners have a generously dimensionedpower unit controlled by a variable speed driveand equipped with a load rating display.On our conventional units, only the bottom rollsare powered. For our highest performance unitsall the rolls are powered.The fi nish of the rolls is adapted to the materialsworked. As standard, they are ground to Ra 0.4but they can also be chromiumplated, superfi ni-shed, micro-sanded, coated with polyurethane orTOPOCROM® treated...

BACKUP ROLLSFor the units designed for heavy gauge or verywide materials, all the rolls are supported by from1 to 7 rows of backup-rolls, depending on thewidth.

This construction is less versatile since it only offers2 adjustment points. However, it allows the instal-lation of a large number of straightener rolls inorder to have a wider range of use.

2 OR 4 DRIVE ROLLSSituated at the straightener entry, they allow the in-troduction of the strip. All DIMECO straighteners areequipped with drive rolls on the entry side with pneu-matic or hydraulic cylinder release.Our independent roll straighteners are also equippedas standard with drive rolls on the exit side of thestraightener. They facilitate adjustment of the equip-ment when working with delicate or aesthetic appea-rance materials.

STRAIGHTENERSFOR THIN OR MAGNETIC STRIPSThese straighteners are designed to straighten thinmaterials (from 0.15 mm upwards). The very goodstraightening quality is ensured by a large num-ber of small diameter straightener rolls, held in acradle adjustable by hand wheels. On certain mo-dels, the straightener rolls are mounted in remo-vable cassettes to facilitate cleaning.

ERGONOMICALLY GROUPED CONTROLSAll the controls of the straightener and its acces-sories are grouped at a single point. Dependingon the specifi ed strip feed direction, the desk andthe penetration adjustment indicators will be si-tuated on the operator’s side.The latter can use a robust and ergonomic remotecontrol to facilitate the strip introduction opera-tions.The controls of the decoiler can also be groupedon the straightener’s control desk.

STRAIGHTENERS WITH INDEPENDENTROLL ADJUSTMENTSThese possess 5 to 11 straightening rolls of 40 mmto 100 mm diameter depending on the model. Thisis most versatile construction.The penetration is adjustable on 2, 3 or 5 rolls. Itallows the best setting to be foundfor each of thematerials used.

CRADLE TYPE STRAIGHTENERSThey are very suitable for wide coils. They havefrom 9 to 21 straightener rolls of 30 mm to 100mm diameter depending on the model.

The table is associated with a variable geometryretractable straightener exit basket (BGV).Depending on the application, the table will belight with pneumatic control or reinforced and hy-draulically operated.In the most demanding applications (HLE strips...),DIMECO offer an architecture with 2 articulatedtables: one mounted on the straightener and theother on the feeder.The movement of the tables is servo-controlled bythe movement of the strip in the pit.

EASY STRAIGHTENER ADJUSTMENTAs standard, with a simple glance at the largedial, the operator can see his penetration settingsto the nearest 1/10th mm.

With the motor-operated penetration adjustment(RMA), all the straightening parameters can bememorised in the parts program accessible fromthe terminal of the feeder.It will also be possible to automatically change thestraightening parameters according to the diame-ter of the coil.A correction roll (RCM) can be installed on the exitside of the straightener to allow the correction ofcoils decoiled from underneath.

MINIMUM MAINTENANCEMaintenance is reduced by the use of bearingswith sealed-for-life or centralised lubrication (ma-nual GCM or automatic GCA).Where aesthetic appearance materials are used,regular cleaning of the straightener’s rolls is ne-cessary. DIMECO offer the "crocodile" openinghead option controlled by pneumatic (DRP-VS) orhydraulic (DRH-VS) cylinder depending on themodel. On the cradle type straighteners, the hea-dhas suffi cient opening stroke to allow easy clea-ning of the rolls.

QUICK CHANGEOVERThe "PITSTOP" configuration allows the introduc-tion and recoiling of the strip without manual in-tervention and allows automatic adjustment of allthe machine parameters when selecting the partfrom the production list menu.

When it is combined with a decoiler and a DI-MECO feeder, the speed of a DIMECO straighte-ner is automatically adjusted to the press rate andto the feed flow-rate.

LOOP CONTROLSIf a loop architecture is chosen, the loop manage-ment is provided by a special control deviceconnected to the straightener. This device must beadapted to the type of material being decoiled.All DIMECO straighteners are delivered with a loopcontrol device. The supply also includesthe strip ten-sion and end of strip detection.Standard or optionally depending on the model, theinformation can also be collected by an ultrasonicsensor which provides contactfree measurement ofthe vertical position of the strip. The line speed canthen be adjusted more effectively and more accu-rately, preventing straightener stoppages.When a loop is provided between the decoiler andthe straightener, the loop control will pilot the va-riable speed decoiler.

The judicious choice of the accessories and options willhave a major impact on the production changeover timesand on operator safety.

FOR ALL MATERIALSThe DIMECO straighteners can be equipped withdevices adapted for the working of high yieldstrength metals or the decoiling of delicate mate-rials (pre-lacquered, copper, mirror-fi nish alumi-nium...).

SIMPLIFIED STRIP INTRODUCTIONThe introduction of the strip into the straightenerand then into the feeder can be a long and dan-gerous job. All DIMECO straighteners are delive-red with an adjustable lateral strip guide on theentry side and with support rolls on the entry andexit sides. Optionally, they can be equipped witha threading pealer with 1, 3 or 4 movements (rein-forced for heavy gauge strips), and with a manualor motor operated symmetrical adjustment stripguide.To facilitate the transfer of the new strip from thestraightener to the feeder, we offer optionally arange of simple or articulated threading tables(TSF).

ADEQUATE PERFORMANCE LEVELSThe decoiling line must under no circumstanceslimit the performance of the cutting line. By its dy-namics, its accuracy and its reliability, the feedermust allow the movement of the strip in the shortestpossible time in order to give the tool-setter themaximum working stroke available.

ACCELERATION, THE KEY FACTORIn most applications the strip feed time is affectedmore by the acceleration of the feeder than by itsmaximum speed. Thanks to the kinematics optimi-sation, the DIMECO feeders can reach an accele-ration of 25 m/s² and a maximum speed of 200m/min.The roll release is operated by a solenoid valveand special pneumatic cylinders or by 2 servo-controlled hydraulic cylinders (DHS) which gua-rantee cutting rates of up to 300 Cpm. Up to 1000Cpm can be achievedwith a mecanical releasecontrol (DMR).

The mechanicalquality of the feederand the performance

of its numerical controlwill have a major impact

on the productivityof the cutting line.

MOVING ASSEMBLY DESIGNSuch performance levels can only be obtained byparticularly careful design of all the feeder com-ponents. The body of the rudder, the moving partof the feeder, consists of a castiron structure ma-chined with great accuracy. It is accurately guidedby needle bearings and thrust ball bearings moun-ted on 2 pivots. The release stroke is limited by amechanical stop adjustable according to the thick-ness of the strip.The movement is transmitted to the top roll by anoriginal kinematic chain with 4 pinions. The back-lash in the transmission is very low, whatever themetal thickness.

HI-SPEC ROLLSTo obtain the best adherence and long life, all rollson the DIMECO feeders are hardened, micro-sandedthen hard chromed at 70 HRC. On the largest mo-dels, for better dynamics, the rolls are tubular andsupported by backup-rolls.

Digital control is the brain of the feed line. It will op-timise the operation of the different machines in itand will communicate with the other parts of the cut-ting line. The terminal is the principal component ofthe humanmachineinterface.The choice of control will be made according to thesize, number and complexity ofthe various cuttingline elements (decoiler, press tool and other peri-pherals). The required degree of automation andcommunication and the available budget will alsobe considered.You will be able to fi nd the system whichsuits yourapplication from among our 4 controls.

ECODRIVE 2Designed on the basis of BOSCH-REXROTH equip-ment, this is the simplest control of the range. It isavailable on small and medium capacity feeders.Cost effective and easy to programme, it is wellsuited to simple applications and tight budgets.

SIMOSTAR® 170 PF console

ACCURACYAll DIMECO feeders are equipped with low iner-tia brushless motors and gearboxes withreducedbacklash. The feed accuracy will thus be determi-ned essentially by the quality of the signal measu-rement and processing sequence. The use of acomplete electronic package (sensors, motors,PLCs) from the same component manufacturer cho-sen among the world leaders ensures exceptionalreliability and positioning accuracy (± 0.05 mm).

FOR ALL MATERIALSDIMECO feeders can be provided with OMD op-tion suitable for the decoiling of delicate mate-rials (pre-lacquered, galvanised, copper,mirror-fi nish aluminium...).

TOOL PROTECTIONAn additional feed measurement device can beinstalled on the strip, either below CRM/B orabove CRM/T. This sensor allows any slippagebetween the measurement of the feeder motorencoder and the actual passage of the strip to bemonitored in real time.One can thus detect any malfunction of the toolor of the press, trigger an immediate stop andprevent damage to the installation.

ATTACHMENT TO THE PRESSThe feeder can be fi xed to the press by a fi xedmounting bracket, manually adjustable in heightRCH, motor activated RMH-C or on an indepen-dent motor activated frame RMH-S for the largestequipment.

MICROPRO® STRAIGHTENERS-FEEDERS

The MICROPRO® solution is ideal for strip thick-nesses of over 1 mm and max. feed pitches limitedto about 800 mm. It is reserved for materials ha-ving no appearance constraints.The MICROPRO® straightening performance levelsare identical to those of the motordriven straighte-ners from which their design is taken. They allowshort line architectures (3 in 1), without loop orwith rear loop.

MOTORIZATION AND ACCURACYThe motor drive of the straightener is replaced bya generously dimensioned brushless motor.It can be associated with the OPTIMASTER® andSIMOSTAR® digital controls.All DIMECO straighteners-feeders are equippedas standard with a strip feed measurement sensor(CRM) in order to provide the same feed accuracyas the feeders alone (± 0.05 mm).The rates achieved range from 100 to 150 Cpm,for a max. speed of 30 to 50 m/min.

of 2 machines in onefor a space saving

of 40 to 50%,without civil engineering.

PINCH ROLLS RELEASEEffi cient pinch rolls release will allow correct ope-ration of the pilots of the progressive cutting tool.On all MICROPRO® units, the basic release func-tion is provided by a pneumatic (POR) or hydrau-lic (PORHyD) control for lifting the traction rollsand the zero torque setting of the motor.With the (PIN) option, a sharper release is provi-ded by the partial opening of the upper part of thehead, by means of two hydraulic cylinders control-led by servo-valves.For more delicate applications (HLE strips), digitalservo-release (PIN-A) will be adopted.In this confi guration, the head opening cylindersare mounted on an eccentric shaft operated by aservo-motor. All the release parameters are thenprogrammable.The MICROPRO® straighteners-feeders benefitfrom most of the options offered for the individualstraighteners or feeders.

STRIP SHEARThis is the heart of the cutting line. Depending onthe sections, the types of materials handled andthe required cutting rate, a mechanical, pneuma-tic or hydraulic operation shear will be chosen.The quality of its design will allow a minimal cut-ting burr and will limit the frequency of sharpe-ning.Cost effective, the pneumatic shears have beendesigned for the fast and accurate cutting of thinand delicate metals: aluminium or polished stain-less steel, copper, silicon steel, etc. They are limi-ted to sections of less than 650 mm².The hydraulic shears are used for heavy sectionsor high yield strength strips. They can be equip-ped with a hydraulic hold down. Very fast, thetype 1730 crankshaft type mechanical guillotineshears can achieve rates of up to 200 Cpm. Theyare designed to be included in production lines.The frame, clear underneath the blades, allows di-rect stacking of the blanks with no intermediateconveyor.
