CLASS G 05 b PATENT TIME FROM 22 NOVEMBER 1958 GRANTED 21 DECEMBER 1961 PUBLISHED 27 FEBRUARY 196T Ans. 10847/1958 on 22/11 1958Therefore a drawing R BAUDER, STUTTGART-SILLENBUCH, FEDERAL REPUBLIC OF GERMANY Ordering bodies with perforated programmers To control a specific course of work processes - e.g. for machine tools, manufacturing steps, advertising devices and the like must have a program, ie. a series of control orders bringa.s to execution one or repeatedly. In this case, it is mostly necessary to maintain the spirit of a given order until the next order begins.

Man liar for detta andamal fidigare anvant kopplingsverk, som hava en kontinuerligt eller stegvis roterande, pa bestamt satt med nockar fOrsedd vals eller liknande, varvid nockarna tjana for manovrering av kontakter eller liknande. For this purpose, couplings are used which are more frequently used, which have a continuous or stepwise rotation, in a certain manner with cams provided with rollers or the like, the cams being used for maneuvering contacts or the like.

Dessa kanda kopplingsverk hava den .nackdelen att aga en endast begransad kopplingsnoggrannhet och for varje nytt program maste de pa kopplingsvalsen anordnade nockarna och de genom dessa manovrerade konttakterna eller liknande andras i forhallande till varandra och eventuellt aven till sin form. These known couplings have the disadvantage of having only a limited coupling accuracy and for each new program the cams arranged on the coupling roller and the contacts maneuvered by them or the like of others must be in relation to each other and possibly also to their shape.

Pa grund av dessa nackdelar anvandes i Rad utstrackning programbarare i form av band eller kort, varvid orderna ph mekanisk, optisk, elektrisk eller magnetisk.vag phforas en bailor lOmplig barare och vidarebefordras fran denna. Vid dessa programgivare kunna bararna latt utbytas och fOrvaras for senare anvandning. Vidare kan varje onskad noggrannhet i ordergivningen uppnhs genom anvandning av erforderligt langa band. Due to these disadvantages, programmers were used to a large extent in the form of tapes or cards, whereby the orders were mechanical, optical, electrical or magnetic. At these programmers, the bars can be easily exchanged and stored for later use. Furthermore, any desired accuracy in ordering can be achieved by using the required length of tape.

Dessa styranordningar hava emellertid en hel del nackdelar. Salunda maste vid orderbefordringen ordersignalen oftast forstarkas pa vagen fran bandet till utlosningsstallet, om ett mellanrela eller ett framfor utlosningsstallet inbyggt forstarkningsslutsteg skall styras. Da for konservering av orderna polariserade re-Ian eller eller relan med stoppkretsar anvandas Ras platsbehovet och kostnaderna for en. dylik antaggning icke ovasentligt. Dartill kommer en Rad stOrningskanslighet och till foljd harav en omfattande Overvakning. However, these control devices have a lot of disadvantages. Thus, when ordering, the order signal must usually be amplified on the road from the belt to the unloading station, if an intermediate relay or a reinforcement final stage built in front of the unloading station is to be controlled. Since for the preservation of the orders polarized re-Ian or or relan with stop circuits, Ras is used for the space requirement and the costs for one. such assumption not insignificant. In addition, there is a number of disturbance probabilities and, as a result, extensive monitoring.

Alla de namnda nackdelarna hos de kanda anordningarna elimineras genom fOreliggande uppfinning i det att ordergivningsorganet for orderoverforing innehaller pneumatiskt eller hydrauliskt phverkade utvidgningskroppar med ett mellan desamma anordnat bistabilt aven i och for sig 'cant kopplingsorgan for manovrering av elektriska kontaktelement. Dessa kontaktelement kunna hogbelastas, sa att man kan avsta fran elektriska forstarkare. All the mentioned disadvantages of the known devices are eliminated by the present invention in that the ordering means for order transfer comprises pneumatically or hydraulically actuated expansion bodies with a bistable shaft arranged therebetween and a separate coupling means for maneuvering electrical contact elements. These contact elements can be highly loaded, so that you can refrain from electrical amplifiers.

Limpligen astadkommas de stabila lagena hos kontaktelementen genom magnetiska krafter eller genom ett bistabilt pa samma satt som en snappfjader verkande mekaniskt organ. Darigenom blir anvandningen av relan Overfloclig, emedan effektutlosningarna kunna styras direkt. The stable layers of the contact elements are preferably achieved by magnetic forces or by a bistable mechanical device acting in the same way as a snap spring. As a result, the use of the relay becomes superfluous, since the power triggers can be controlled directly.

Med fOrdel kan ordergivningsorganet vara sammansatt av likartade ordergivningsenheter, som aro anordnade i en eller flera rader. Vid anordnandet av ordergivningsenheterna flera rader kunna dessa for undvikande av en overlappning av orderkanaler yarn sidoforskjutna i forhallande till varandra. With advantage, the ordering means can be composed of similar ordering units, which are arranged in one or more rows. When arranging the ordering units several rows, these can be laterally offset in relation to each other in order to avoid an overlap of order channels.
