2. Operating Pinciples
Diagram: Principlesofa CamSwitch Unit
Aprincipleforbettercomprehension ofthe function ofaCamSwitchUnitisherepresented. It has3
outputswith the following cams:
Output 1: Cam1: Switch-ON position60° Switch-OFF position 85°
Cam2: Switch-ON position95° Switch-OFF position 145°
Cam3: Switch-ON position325° Switch-OFF position 355°
Output 2: Cam1: Switch-ON position5° Switch-OFF position 20°
Cam2: Switch-ON position95° Switch-OFF position 145°
Output 3: Cam1: Switch-ON position30° Switch-OFF position 85°
The positionsofthe output signals,herepresented asthree tracks,occurwhen the three camdisks
turn anti-clockwise past a sensor, which scansthe camson the 0°-axis.
In amechanicalcamswitchunit, the switchinterval,i.e. the range between switch-ONand switch-OFF
position aredetermined bythe length ofthe cam.The length and the position ofthe camcan onlybe
varied marginallyand thisismechanicallyhighlydemanding and timeconsuming. With CamCon such
adjustmentscan be realised inafraction oftime; inaddition, therecan be anynumberoftracks.A
measuring systemwhichisfitted to the devicereportsthe position to the CamCon. The CamCon
comparesitwith the programmed switch-ONand Switch-OFF positionsofall outputs.Ifthe position
liesinthe range ofaprogrammed switch-ON/switch-OFF position (cam),then the respectiveoutputs
are active.

2.1. SpeedCompensation
Eachmechanicalswitchcomponent (e.g. shield, magneticvalve)hasadelaytime, i.e. the time
between the startsignaland the actualswitching ofthe contacts.In processeswherepositioning is
executed on amoving system,thiscan causeproblems.Ifsuchaprocess isdriven with different
speeds,different positionsarecaused. Toavoidthishappening, newtimingsforthe switchsignalsof
each speed would have to be calculated.
In orderto ilustrate the complicated issuessurrounding delaytimeorspeed compensation, thiswill be
shownon the exampleofapackaging machine. In the process showninthe diagram,aglue point has
to be placed in an exactlydefined spot on a moving papertrack.

Pointswheretheglue

different speeds .
paper track
encoder
CamCon The systemhasthe following parameters:
vp-Speed ofthe papertrack
vT-Falling speed ofthe drop ofglue
d - Distance between the glue nozzle and
the papertrack
TMV - Delaytime ofthe magneticvalve
Without speed compensation the following would happen:
Assoon asthe measuring systemhasreached acertainposition, the CamCon sendsasignalto the
magneticvalve. The glue nozzle opensfora short time during whichadrop of glue ejects.Between the
startofthe impulseand the exitofthe drop timepasses,whichismainlycaused bythe delaytimeof
the magneticvalveTMV..Afurtherdelayiscaused bythe timewhichthe droplet needsto pass the
distance between the glue nozzle and the surface ofthe paper.
Thisflight time iscalculated asfollows:
tFlight = d
vT
In totaltherethe delaytimeistFlight+TMV. During thistimethe papertrackmoveson byaspecific
distance x.
It wouldnowbe possibleto movethe position, wherethe magneticvalveisswitched on, forwardbya
specificamount, sothat the glue droplet hitsthe samespot againasduring standstill.In thiswaya
speed compensation iscreated whichworksonlyat aspecificspeed ofthe paper.Assoon asthe
speed ofthe deviceand consequentlythat ofthe papertrackis,forexample, doubled, the hitpoint of
the glue droplet isshifted bythe distancex,sothat, without anyspeed compensation, itwouldmove
backward bydouble the distance (2 ⋅x) in total.
The automaticspeed compensation ofthe CamCon makesitnowpossibleto driveprocesseswith
variablespeed; CamCon registers the speed ofthe devicecontinuouslyand adjuststhe camswhich
determine the switchtimepoints"OnLine"depending on the speed. Thishasthe effectthat the
outputsforthe switchcomponentsareswitched ONorOFF earlier.The direction ofthe movement is
ofno significance in thisinstance.

Asmall example in figureswasdesigned to eludicate:
Supposing the drivecylinderwith the measuring systemhasacircumferenceof360mm,sothat one
millimeterofthe circumference correspondsto exactlyone angle degree ofthe measuring system.
The device hasthe following parameters:
vdroplet = 20m/s
d = 20cm
TMV = 20ms
Thisresultsin the following flight time ofthe droplet:
tFlight= d
vT=0,2m 20m/s = 10ms
The totaldelaytime isthen Tdead, altogether =TMV +tFlight =20ms+10ms=30ms
During thistimethe papertrackmoveson bythe distancex=vpaper ⋅Ttotaldelay. =1m/s ⋅30ms=
30mm.In orderto compensate the delaytime, the switchpoint forthe magneticvalvemustbe moved
forward by30°.
Ifthe speed ofthe deviceand consequentlythat ofthe paperisdoubled vpaper,then the distancexis
also doubled bythe speed ofthe papertrack. In thiscase the switch point must be moved by60°.
Note: Pleasetakeinto account intheseexplanationsthat delaytimeisofafixed size, whichis
determined bythe mechanicalconstantsofthe set and switchcomponentsand bythe
dimensionsofthe construction and therefore doesnot change!
Ifthe totaldelaytimeof30mswasprogrammed into the respectiveoutput ofCamCon, then the glue
droplet would alwayshit the right spot, regardless ofthe speed.

2.1.1. Measuring delaytimeforSpeedCompensation
Severalwaysofmeasuring delaytime ofa relayorvalve are available.
2.1.1.1. Measuring delaytimethrough actual differences
Firstthe switch-ONpoint ofavalveorrelayisprogrammed. Weassumethat the programmed switch
point liesat 200 degreesinthiscase. Ifthe machine isdriven with aspeed offorexample40 rpm,a
shiftoccurs due to delaytime. Thisshiftisthen measured and, inthisexample, will amount to 40
degrees.
Warning: Forthe calculation ofthe shiftthe programmed delaytimeinthe camswitchunitmustbe
set to zero!
The delaytime ofthe switch component isnowcalculated asfollows:
Delaytime (in sec. )= ∆way(in °)*60 (sec./min.)
speed (in rpm)*360 (°/turn)
Delaytime (in sec. )= 40 *60
40 *360 =0.1667 sec.
The resultant delaytime isthen entered into the camswitch unit.
See Chapter"6.3. The dead time compensation"an page 15.
2.1.1.2. Measuring delaytimebymeansof different measuring points
Firstthe switchpoint iscalculated at aspeed of,forexample, 50 rpm.Weassumethat the
programmed switchpoint liesat 200°inthiscase. The second measurement istaken at aspeed of80
rpm The necessaryswitchpoint mustbe set to 160°,ifthe exactswitchpoint isto be alsoachieved at
80 rpm.
Warning: Forthe calculation ofthe twoswitchpointsthe programmed delaytimeinthe camswitch
unit must be set to zero!
The delaytime ofthe switch component isthen calculated with the following formula:
Delaytime (in sec. )= ∆way(in °)*60 (sec./min.)
∆speed (in rpm)*360 (°/turn)
Delaytime (in sec. )= 40 *60
30 *360 =0.222 sec.
The resultant delaytime isthen entered into the camswitch unit.
See Chapter"6.3. The dead time compensation"an page 15.
Since the entered delaytime shiftsthe switch point, the previouslyprogrammed cammust be changed.
Forthe calculation ofthe exact switch-ON position, the difference to the speed Orpm(here using 50
rpm)must be added to the first measured switch-ON point (here 200°). The difference iscalculated
with the following formula:
∆way(in degrees) = dead time (in sec. )* ∆time (in min-1)*360 (degrees/rotations)
60 (sec./min.)
∆way(in degrees) = 0.222 *50 *360
60 =66.6 degrees
The switch-ON point ofthe camisnowshifted from200°byapprox. 67°to 267°.
