Viktdoseringen sker medelst till lutande lage installbara, sasom vaganordning utbildade transportband, vardera med en forradsbehallare med en den utmatade godsmangden bestammande, av en motor installbar slid e. d., varjanate drivmotorer aro anordnade att driva transportbanden med konstant hastighet. CLASS 80 a: 7 / INT. CLASS B 28 b PATENT PERIOD FROM 4 OCTOBER 1960 PROVIDED ON 9 AUGUST! 1962 PUBLISHED ON 30 OCTOBER 1962 Ans. 9487/1960 den 4/10 1960tvd drawings W HACHLER, WETTINGEN, SWITZERLAND Device for automatic weight weighing of bulk goods with variable mixing composition The present invention relates to a device for automatic weight dosing of bulk goods with variable mixing composition. The weight dosing takes place by means of inclined, installable conveyor belts, each with a storage container with a quantity of the discharged goods, a motor installable slide, etc., varjanate drive motors aro arranged to drive the conveyor belts at a constant speed.

Forradsbehallaren ir i regel utford sasom en silo och har nedtill en uttagningsoppning, som alltefter behov kan Oppnas i storre eller mindre omfattning medelst en slid. For betongblandningar aro exempelvis olika cement-, grus- och sandsilos anordnade. Doseringen av de enskilda komponenterna i en betongblandning skedde ursprungligen genona att dessa komponenter vagdes upp. Efter uppvagning av de for varje fall foreskrivna mangderna av de enskilda komponenterna infordes dessa satsvis i blandningsmaskiner. Detta satt att framstalla betong ãr emellertid a ena sidan omstandligt och tidsodande och erbjuder andra sidan ingen garanti for att blandningsforhallandet alltid fOrblir noggrant detsamma. The storage container is usually challenged like a silo and has a withdrawal opening at the bottom, which can be opened to a greater or lesser extent by means of a slide as required. For concrete mixtures, for example, different cement, gravel and sand silos are arranged. The dosing of the individual components in a concrete mix was initially done by weighing these components. After weighing the quantities of the individual components prescribed for each case, these were introduced in batches into mixing machines. However, this method of producing concrete is on the one hand cumbersome and time-consuming and on the other hand offers no guarantee that the mixing ratio will always remain exactly the same.

Visserligen aro anordningar kanda med transportband f8r viktdosering av massagods, t. ex. sand och grus, vid vilka foranderliga massagodsmangder erhallas genom att transportbandets hastighet Andras. Detta medfor emellertid olagenheten att den transporterade massagodsmangden per tidsenhet tillater ett variationsforhallande av hogst c:a 1: 10, enar transportbandets hastighet joke kan Ras i godtycklig utstrackning. I manga fall aro emellertid de praktiska kraven sadana, att ett betydligt mera vidstrackt variationsomrade erfordras. En ytterligare n:ackdel hos dessa kanda anordningar, bestar dari att doseringsnoggrannheten är otillfredsstallande, sarskilt i narheten av bandhastighetens ovre och nedre 6ransvarden. Admittedly, devices are known with conveyor belts for weight dosing of bulk goods, e.g. sand and gravel, at which variable quantities of pulp are obtained by the speed of the conveyor belt Andras. However, this entails the disadvantage that the transported mass of bulk goods per unit of time allows a variation ratio of at most about 1:10, if the conveyor belt speed joke can be Ras to any extent. In many cases, however, the practical requirements are such that a much wider range of variation is required. A further disadvantage of these known devices is that the dosing accuracy is unsatisfactory, especially in the vicinity of the upper and lower transmissions of the belt speed.

A andra sidan aro aven viktdoseringsanordningar for massagods kanda, vid vilka en slid anordning finnes for reglering av de olika massagodsmangdernas passage. Inreglering ph onskad doseringsmangd och andring av det 8n skade vardet har emellertid antingen joke varit automatiskt eller ocksa mycket komplieerad och utsatt for stOrningar. En vidare olagenhet är att hela installningsanordningen maste an.ordnas direkt vid massagodsets forradsbehallare resp. vid vagen och dad& i hog grad är utsatt for skakningar, fororeningar och atmosfarens inverkan. Dessutom an Overvakningen av det installda vardets undring besvarlig for betjaningspersonalen, d'a de enskilda doseringsstallena exempelvis i grusverk, kunna ligga langt frau varandra. On the other hand, there are also weight dosing devices for bulk goods, in which a sliding device is present for regulating the passage of the various quantities of bulk goods. Adjusting the desired dosage amount and changing the 8n injury value, however, has either been a joke automatically or also very complicated and prone to disturbances. A further disadvantage is that the entire installation device must be arranged directly at the bulk goods' storage container resp. by the road and dad & is highly exposed to shaking, pollution and the impact of the atmosphere. In addition, the monitoring of the astonishment of the installed guard responsible for the operating staff, the individual dosing stalls, for example in gravel works, can be far apart.

Daseringsanordningar aro slutligen kanda med flera transportband, som samverka med en vaganordning, men f6r installning av de enskilda komponentandelarna maste dock en vikt installas for hand, sh, att vagen sthndigt Or i jamvikt. Dosing devices are finally known as having several conveyor belts, which co-operate with a carriage device, but before installing the individual component parts, a weight must be installed by hand, so that the carriage is constantly in equilibrium.

Till skillnad harifran grundar sig foreliggande uppfinning pa att astadkomma en anordning for automatisk viktdosering av massagods, vid vilken de olika blandningskomponenternas proportioner standigt skola vara foranderliga och den i verkligheten transporterade vikten skall kunna overvakas ph ett centralt ställe. Detta problem loses enlig uppfinningen pa enkelt satt °eh med ringa konstruktionsarbete genom att varje va.ganordning star i forbindelse med en dess utslag avkannande givare, och att en for varje vaganordning anbragt mottagare Or anbragt yid ett centralt stalle, saint att en elektrisk anordning Or anordnad att ph elektrisk vag overfora de av givaren faststallda utslagen till mottagaren, vilken Or forsedd med kontakter, som aro inkopplade i slidmotorns stronikrets och Oro anordnade att installa sliden pa ett mot ett installbart nominellt eller onskat varde svarande lase. In contrast, the present invention is based on providing a device for automatic weight dosing of bulk goods, in which the proportions of the various mixing components should be constantly variable and the weight actually transported can be monitored at a central location. This problem is solved according to the invention in a simple manner even with little construction work in that each weighing device is connected to a sensor which detects its deflection, and that a receiver Or arranged for each weighing device is arranged in a central stable, so that an electrical device Or arranged to ph electrically vaguely transmit the projections determined by the sensor to the receiver, which Or is provided with contacts which are connected in the stronikret of the slide motor and Oro arranged to install the slide on a read corresponding to an installable nominal or desired value.

Till skillnad Iran kanda anlaggningar for framstallning ay blandningar av bestamd sammansattning medfor anordningen enligt uppfinningen den vasentliga fordelen, att man 2— — standigt erhaller den exakt lika och forutbestamda blandningen med riktiga komponentforhallanden. De enskilda komponenterna kunna darvid forandras steglost, och de installda vardena hallas konstanta. Vid en praktiskt utprovad anlaggning uppgick exempelvis variationsomradet for de enskilda komponenterna till 0-3500 kg per minut. Unlike Iran, plants for the preparation of mixtures of a certain composition have the essential advantage of the device according to the invention that one obtains the exact same and predetermined mixture with correct component ratios. The individual components can thereby change steplessly, and the installed values are kept constant. In a practically tested plant, for example, the range of variation for the individual components was 0-3500 kg per minute.

En annan fordel med anordningen enligt uppfinningen bestar i att anlaggningen kan automatiseras till relativt ringa kostnad pa sadant satt att schablonartade styrorgan kunna anvandas for bestamda, standigt aterkommande blandningsforhallanden. Another advantage of the device according to the invention is that the plant can be automated at a relatively low cost in such a way that standard-like control means can be used for certain, constantly recurring mixing conditions.

Transportbanden under de enskilda utloppsoppningarna lopa med konstant hastighet, sa att vaganordningen standigt mater och indikerar den per tidsenhet transporterade viktmangden, ear transportbandets vikt alltid Or densamma och dull& ieke behover tagas hansyn till. Vid tomt transportband anges salunda vardet »0» genom motsvarande in-stunning av skalan eller visaren. The conveyor belts under the individual outlet openings run at a constant speed, so that the carriage device constantly feeds and indicates the amount of weight transported per unit time, the weight of the conveyor belt is always the same and dull & ieke needs to be taken into account. In the case of an empty conveyor belt, the value »0» is thus indicated by the corresponding in-stunning of the scale or the pointer.

Fran det centrala kontrollstallet eller regleringsstallet kan varje variation av blandningsforhallandet genast faststallas, och man kan ddrifran utfora erforderliga atgarder for att aterstalla det i5nskade forhallandet. From the central control or control unit, any variation of the mixing ratio can be determined immediately, and the necessary steps can be taken to restore the desired ratio.

Pa. bifogade ritning visas en utforingsform av uppfinningsforemalet sasom exempel. Fig. 1 visar schematiskt, delvis i sektion, ett antal efter varandra anordnade forradsbehfillare med vaganordningar och olika transportband. Fig. 2 visar i stone skala en. sidov av utloppet fran forradsbehallaren med regleringsslid oeh drivmotor.

Fig. 4 visar schematiskt en medelst en schablon pa ett bestamt blandningsforhallande installd anordning, och fig. 5 visar en sektion genom anordningen enligt linjen V—V i fig. 4. Pa. The accompanying drawing shows an embodiment of the object of the invention as an example. Fig. 1 schematically shows, partly in section, a number of storage containers arranged one after the other with trolley devices and different conveyor belts. Fig. 2 shows in stone scale one. side of the outlet from the storage tank with control slide and drive motor. Fig. 3 shows seematically, partly in perspective and partly as a wiring diagram, the means for controlling the device. Fig. 4 schematically shows a device installed by means of a stencil on a specific mixing ratio, and Fig. 5 shows a section through the device according to the line V-V in Fig. 4.

Den i fig. 1 schematiskt visade massagodsforradsbehallaren eller silobehallarna 1 och 2 innehalla vardera en komponent av den massagodsblandning som skall framstallas. I varje silos botten finnes en utloppskanal 3 med en uttagningsoppning 4, som oppnas eller stanges medelst en regleringsslid 5 mer eller mindre alltefter slidens lage. Regleringssliden 5 mandvreras av en motor 6 Over en reduktionsvaxel 7, ett kugghjul 8 och ett kuggsegment 9. Kuggsegmentet 9 Or fast forbundet med regleringsslidens 5 sidovagg 10 och kan tillsammans med denna svangas kring en axel 11. DA motorn 6 driver kugghjulet 7 i riktning moturs enligt fig. 2, svanges kuggsegmentet 9 medurs, och slidens 5 avstangningsplatta 12 svanges uppat, sa att uttagsoppningen 4 frigiyes i motsvarighet till storleken av uppatsvangningen hos regleringsslidens 5 avstangningsplatta 12. The bulk goods container or silo containers 1 and 2 schematically shown in Fig. 1 each contain a component of the bulk material mixture to be produced. At the bottom of each silo there is an outlet channel 3 with a withdrawal opening 4, which is opened or closed by means of a regulating slide 5 more or less according to the layer of the slide. The control slide 5 is maneuvered by a motor 6 Over a reduction shaft 7, a gear 8 and a gear segment 9. The gear segment 9 is fixedly connected to the side cradle 10 of the control slide 5 and can be pivoted together with it about a shaft 11. The motor 6 drives the gear 7 in a counterclockwise direction. according to Fig. 2, the tooth segment 9 is pivoted clockwise, and the support plate 12 of the slide 5 is pivoted upwards, so that the outlet opening 4 is released corresponding to the size of the upward swing of the support plate 12 of the adjusting slide 5.

Det fran uttagsoppningen 4 utstrommande massagodset nedfaller pa ett av transportban den 13. Detta uppbares av en vaganordning 14, som medelst en visare 15 pa. skalan 16 anger den for tillfallet pa transportbandet 13 befintliga mangden av det for transport avsedda godset. Skalans 16 skalindelning kan kalibreras efter den per tidsenhet transporterade vikten. The pulp flowing out of the outlet opening 4 falls on one of the conveyor tracks on the 13th. This is supported by a carriage device 14, which by means of a pointer 15 on. the scale 16 indicates the quantity of the goods intended for transport incidentally on the conveyor belt 13. The scale division of the scale 16 can be calibrated according to the weight transported per unit time.

Den fran de olika silobehallarna, t. ex. 1 och 2, till de ddrunder befintliga transportbanden 13 utstrommande mangderna av de enskilda komponenterna fora& alla till ett samlingstransportband 17, som transporterar dessa i skikt paforda komponenter till en blandningsbehallare eller en blandningstrumma, fran vilken standigt en blandning med konstant komportentfOrhallande kan uttagas. Vaganordningens utslags- eller indikeringsrorelse Overfores genom fjarroverforingsorgan till en indikeringsanordning vid ett centralt kontrollstalle. I motsvarighet till visarna 15 och skalorna 16 Oro indikeringsanordningar vid kontrollbordet forsedda med visare 19 och skalor 20, som aterge samma indikering som varje motsvarande visare 15. Visarna 15 och 19 aira sig fullstandigt synkront med hjalp av en potentiometeranordning, ett magnetiskt eller elektriskt roterande faltsystem resp. en s. k. elektrisk axel med generator och synkronmotor. En bestamd vinkelforskjutning hos givaren 31 astadkommer salunda en exakt lika vinkelforskjutning hos mottagaren 33. PA kontrollbordet Or salunda for va.ganordningen till varje enskild silo anordnat ett indikeringsinstrument, som standigt anger den per tidsenhet frail varje silo tillffirda viktinfingden. The one from the different silo containers, e.g. 1 and 2, the quantities of the individual components flowing out to the underlying conveyor belts 13 are all fed to a collection conveyor belt 17, which transports these layered components to a mixing container or a mixing drum, from which a mixture with a constant component conveyor can be permanently withdrawn. Movement or indication movement of the weighing device Transferred by remote transfer means to an indicating device at a central control stall. Corresponding to the hands 15 and the scales 16 Concerned display devices at the control table are provided with hands 19 and scales 20, which display the same indication as each corresponding hand 15. The hands 15 and 19 operate completely synchronously by means of a potentiometer device, a magnetic or electrically rotating folding system. resp. a so-called electric shaft with generator and synchronous motor. A definite angular displacement of the sensor 31 thus provides an exactly equal angular displacement of the receiver 33. On the control table Or for the device to each individual silo arranged an indicating instrument which constantly indicates the weight finger supplied per unit of time from each silo.

Fig. 3 visar nedtill schematiskt en vaganordning med transportband 13, som drives av en motor 21 och uppbares i stOdpunkten 50, sA att det kan utf8ra svangningsrorelser. Vaganordningens yttre ande Ar upphangd pa. en dragfjader 51. Vaganordningens utslagsrorelser overforas genom en stang 22 till en tvaarmad havarm i vaganordningen 14. Denna havarm paverkar med ett i en styrning 24 lagrat stilt 25 en kuggstang 26, som i sin tur vrider ett kugghjul 27, varigenom en utvaxling av rorelsen. astadkommes. Kugghjulet 27 är fast anbragt pa. en axel 28, som uppbar visaren 15, vilken rOr sig framfor skalan 16. Med axeln 28 ár vidare ett ankare 29 till ett rotationsfaltsystem e. d. fast forbundet, och ankarets polskor 30 aro elektriskt sa forbundna med polskorna 32, att ankarets 29 rorelse synkront Overf Ores till det pa avstand vid kontrollstallet befintliga ankaret 34. Givaren 31 Astadkommer salunda en exakt lika rorelse hos den avlagset befintliga mottagaren 33 pa elektrisk vag. Fig. 3 schematically shows at the bottom a carriage device with conveyor belt 13, which is driven by a motor 21 and is carried in the stand point 50, so that it can perform oscillating movements. The outer spirit of the weighing device is suspended on. a tension spring 51. The stroke movements of the carriage device are transmitted through a rod 22 to a heated arm in the carriage device 14. This lever arm acts with a post 25 stored in a guide 24 a rack 26, which in turn turns a gear 27, whereby an exchange of the movement. achieved. The gear 27 is fixedly mounted on. a shaft 28, which carries the pointer 15, which moves in front of the scale 16. With the shaft 28 there is further an anchor 29 to a rotating field system or fixedly connected, and the pole shoes 30 of the armature are electrically connected to the pole shoes 32, that the movement of the armature 29 synchronously to the armature 34 located at the control station. The sensor 31 thus achieves an exactly equal movement of the remote receiver 33 on an electric scale.

Ankaret 34 ar fast anbragt pd. en axel 35, som aven uppbar visaren 19 &mufti'. skalan 20. Over skalan 20 dr vidare en for angivande av det onskade vardet avsedd installbar visare 36 roterbart anbragt, som ar rotationsfast fastsatt pa en hylsa 37, vilken Or anordnad ko- — —a axiellt med axeln 35 och omger denna. Visarens 36 installning sker for hand medelst ett handtag 84, en axel 39 och ett kugghjul 40, som ingriper med ett pa hylsan 37 fast kugghjul 38. The anchor 34 is permanently mounted on. a shaft 35, which also carried the pointer 19 & mufti '. the scale 20. Above the scale 20 there is furthermore mounted an installable pointer 36 intended for indicating the desired value, which is rotatably mounted on a sleeve 37, which is arranged co-axially with the shaft 35 and surrounds it. The pointer 36 is installed by hand by means of a handle 84, a shaft 39 and a gear 40, which engages with a gear 38 fixed to the sleeve 37.

Pa axeln 35 aro tva. koaxiellt i. forhallande till varandra anbragta kamskivor 42 och 41 installbara, vilka i och for inbordes installning Aro vridbara, varvid de under driften medbringas i axelns 35 rotation. Pa axeln 35 aro tva. coaxially in relation to each other arranged cam discs 42 and 41, which can be rotated in and for inboard installation Aro, whereby they are brought into the rotation of the shaft 35 during operation.

Vid kugghjulet 38 aro tva elektriska stromstallare 43 och 44, foretradesvis mikrostromstallare, sá anbragta, att de kunna samverka med de hada kamskivorna 41 och 42. En. kopplingsarin 45 till mikrostromstallaren 43 anligger mot kamskivans 41 omkrets, och en kopplingsarm 46 till mikrostromstallaren 44 anligger mot kamskivans 42 omkrets. Da visaren 19 eller visaren 36 installes, slapa kopplingsarmama 45 och 46 pa utspranget till den ena eller den andra kamskivan tills de infalla i kamskivans 41 fordjupning 47 resp. kamskivans 42 fordjupning 48. Da kopplingsarmarna ligga mot ett kamutsprang, ãr mikrostromstallarens stromkrets sluten, vilket medfor att motorn 6 sattes i funktion for manovrering av regleringssliden 5 i den ena eller andra rotationsriktningen Over ett rela 49. I mittla.- get, dvs. da. visarna 19 och 36 ligga noggrant Over varandra, ar ingen av mikrostromstallarna 43, 44 inkopplad, varfiir drivmotorn 6 joke roterar och regleringsslidens 5 momentana lage bibehalles. Om den pa transportbandet vilande massagodsvikten overstiger installningen av det Onskade vardet, inkopplas drivmotorn 6 i den mot stangning av regleringssliden 5 svarande rotationsriktningen, sä att en mindre mangd gods nedfaller pa transportbandet Iran uttagsoppningen. Om den pa transportbandet liggande vikten ãr for lag, inkopplas drivmotorn 6 i motsatt rotationsriktning, I Or att Oka uttagsoppningens storlek och armed den utmatade massagodsvikten. I stallet for tva kamskivor 41, 42 kan Oven endast en enda kamskiva anvandas, om intet avseende fastes vid mitt- eller medellagets installbarhet. At the gear 38 are two electric switches 43 and 44, preferably micro-switches, arranged so that they can co-operate with the had cam disks 41 and 42. One. the coupling arm 45 of the microstreamer 43 abuts against the circumference of the cam disc 41, and a coupling arm 46 of the microstrum shutter 44 abuts against the circumference of the cam disc 42. When the pointer 19 or the pointer 36 is installed, relax the coupling arms 45 and 46 on the projection of one or the other cam disc until they fall into the recess 47 or 47 of the cam disc 41, respectively. the recess 48. When the coupling arms lie against a cam projection, the circuit of the microcurrent switch is closed, which means that the motor 6 is put into operation for maneuvering the control slide 5 in one or the other direction of rotation Over a relay 49. In the middle position, ie. da. the hands 19 and 36 lie exactly one above the other, none of the microstream stalls 43, 44 are connected, for which the drive motor 6 jokes rotates and the instantaneous position of the control slide 5 is maintained. If the bulk material weight resting on the conveyor belt exceeds the installation of the desired value, the drive motor 6 is engaged in the direction of rotation corresponding to closing of the control slide 5, so that a smaller amount of goods falls on the conveyor belt Iran outlet opening. If the weight lying on the conveyor belt is too low, the drive motor 6 is engaged in the opposite direction of rotation, in order to increase the size of the outlet opening and arm the discharged bulk material weight. Instead of two cam discs 41, 42, only a single cam disc can be used, if no respect is attached to the installability of the middle or middle layer.

I detta fall samverka bada mikrostromstallarna 43, 44 med samma kamskiva. Genom inoch urkoppling av motor. i den for tillfallet motsvarande rotationsriktningen, sker en inpendling till den onskade vikten, vilken skall transporteras av transportbandet per tidsenhet. Genom att forandra skivornas 41 och 42 inbordes lage kan noggrannheten, dvs. toleransvikten, installas, vars Over- eller underskridande medfor inkoppling av motor. 6 i den ena eller andra rotationsriktningen. In this case, both the microcurrent stables 43, 44 cooperate with the same cam disc. By engaging and disengaging the motor. in the direction corresponding to the rotation, an oscillation takes place to the desired weight, which is to be transported by the conveyor belt per unit of time. By changing the inboard position of the discs 41 and 42, the accuracy, ie. tolerance failure, is installed, whose Over- or Underrun entails the connection of the motor. 6 in one or the other direction of rotation.

I fig. 4 och 5 visas en utforingsvariant, vid vilken en forutbestamd blandningstyp kan in- stallas genom schablonartade organ. FOr detta andamal overfores i princip visarens 6 rotationsrorelse till en ratlinjig stracka, och dess storlek fastlagges av en schablon. For detta andamal a" en rulle 55 rotationsfast forbun- den med visaren 36, och i rullens 55 spar 56 Or en lina eller kabel 57 upplindad och fast.

For battre overskadlighets skull visar fig. 4 endast en av de sex, inbordes lika anordningarna. Figures 4 and 5 show a design variant in which a predetermined type of mixture can be installed by means of standard means. For this purpose, in principle, the rotational movement of the pointer 6 is transmitted to a straight line, and its size is determined by a stencil. For this purpose a roller 55 is rotationally connected to the pointer 36, and in the groove 56 of the roller 55 Or a rope or cable 57 wound and fixed. fixed: at the roller 55. The line 23 Or connected to a traction spring 59, which exerts a traction force in this line.The device Or said challenge, that the spring 59 is under slight bias in the needle 36 nonage.The line 57 Or ford Over several breaking rollers 60 and Or fixed to an abutment member 61, such as Or Hit displaceable styli 1 a tube 61. Each mixing component belongs to a saluncla ea such device.For better clarity, Fig. 4 shows only one of the six, inboard equal devices.

FOr att hestamda mangdforhallanden, som standigt aterkomma, icke skola behova instal- las sarskilt for varje gang, Or denna schablon- styrning anordnad. En schablon 63, som Or forsedd med utskjutande utsprang 64, fastes pa. en barplatta 65 medelst klamarmar 66. De av var sin fjader 67 paverkade klamarmarna 66 ingripa darvid i en klack eller en slits 68 i schablonen 63 och fasthalla denna i sitt lage. In order that horse-like conditions, which constantly recur, should not have to be installed separately for each time, this standard control is arranged. A stencil 63, which Or is provided with projecting projections 64, is attached to. a bar plate 65 by means of clamping frames 66. The clamping frames 66, each of which is affected by the spring 67, thereby engage in a lug or a slot 68 in the stencil 63 and hold it in its position.

Den foretradesvis av plat bestaende schablonens 63 utsprang 64 inskjuta kolvarna 61 i roren 62, alltefter dessa utsprangs olika Mug- der. Harigenom drages linan 57 pa motsvarande satt, och varje visare 36 installes pa. ett pa forhand bestamt varde. Om en material- komponent icke erfordras, bortfaller ifragavarande utsprang sasom visas i fig. 4 pa. den vanstra sehablonsidan tillsammans med an- slagsorganet 61'. Ju langre utsprangen. 64 Oro, desto mera vrides visaren 36. Schablonen ham vidare en slits 69, som Or anordnad mellan rOren 62. Dessa slitsar 69 Oro sa breda, att en mikrostromstallare '70 kan inrymmas i var- dera av dem. Alltefter slitsarnas 69 djup aro dessa mikrostromstallare 70 oppna eller slutna efter schablonens 63 pasattning. Till varje anslagsorgan 61 och salunda till varje styranordning resp. materialkomponent hor en sadan mikrostromstallare 70, som astadkommer att ifragavarande del endast kan bringas funktion cm tillhorande mikrostramstallare 70 Or sluten, da den exempelvis in- och urkopplar de elektriska motorrelaerna. Vid si- dan am schablonen 63 kunna Oven ytterligare mikrostromstallare 70 ,anordnas, som exempelvis kontrollera riktig insattning av schablonen. 63 och fOrst harefter deblockerar anlaggningen eller utfora andra funktioner. Preferably, the projections 64 of the flat stencil 63 insert the pistons 61 into the tubes 62, according to which various mudders protrude. Thereby the line 57 is drawn in the corresponding manner, and each pointer 36 is installed on. a pre-determined value. If a material component is not required, the protrusion in question, as shown in Fig. 4 pa, disappears. the left side of the template together with the anchor 61 '. The longer the jump. 64 Oro, the more the pointer is turned 36. The stencil further has a slot 69, which Or arranged between the tubes 62. These slots 69 Oro are so wide that a microstrater '70 'can be accommodated in each of them. Depending on the depth of the slots 69, these microstream switches 70 are open or closed after fitting the stencil 63. To each stop means 61 and salunda to each control device resp. material component, such a microcurrent switch 70 is provided, which ensures that the part in question can only be brought into operation with the associated microcomputer switch 70 or closed, as it, for example, switches the electric motor relays on and off. At the side of the stencil 63, additional microstream switches 70 can also be arranged, which, for example, check correct insertion of the stencil. 63 and only then unblock the system or perform other functions.
