Elektromotordrevet aktuator med sikkerhedsafbryder.Electric motor actuator with safety switch.
Opfindelsen angår et elektromotordrevet aktiveringsorgan til indstilling af et møbel eller en møbeldel, hvilket aktuator via en elektromotor drivbart drivaggregat, som via et indstillingsorgan indvirker på det indstillelige møbel eller den indstillelige møbeldel, og har en styreanordning for elektromotoren, i det mindste en endestopafbryder, som, når dens position nås, bevirker en afbrydelse af elektromotoren, samt mindst en sikkerhedsendestopafbryder.BACKGROUND OF THE INVENTION The invention relates to an electric motor actuator for adjusting a piece of furniture or a furniture part, which actuates via an electric motor driven drive unit which acts via a setting member on the adjustable furniture or the adjustable furniture part, and has an electric motor control device, at least one limit switch, which , when its position is reached, causes an electric motor shutdown, as well as at least one safety end switch.
Aktuator af den nævnte art omsætter en gevindspindels rotationsbevægelse til lineærbevægelsen af en drejningsstift ført spindelmøtrik. Også muligheden for en aksialt stationært drevet spindelmøtrik er kendt, hvorved en drejnings-stift ført gevindspindel ved hjælp af den drevne spindelmøtrik udfører en gennemgående lineærbevægelse.The actuator of the aforementioned type converts the rotational movement of a threaded spindle to the linear movement of a rotary pin guided spindle nut. Also known is the possibility of an axially stationary driven spindle nut, whereby a rotary pin guided spindle by means of the driven spindle nut performs a continuous linear movement.
I aktiveringsorganets endepositioner afbrydes elektromotoren ved hjælp af endestopafbrydere.In the actuator end positions, the electric motor is switched off by means of limit switches.
Endestopafbryderne udløses ved hjælp af aktiveringsfremspring på spindelmøtrikken eller ved hjælp af aktiveringselementer på den lineært forskydelige spindel, når en af endepositionerne nås. Fra DE 88 06 094, DE 89 03 603 og DE 91 03 817 kendes sådanne aktiveringsorganer med endestopafbrydere til indstilling af møbler eller møbeldele.The end stop switches are triggered by actuating projections on the spindle nut or by actuating elements on the linearly displaceable spindle when one of the end positions is reached. From DE 88 06 094, DE 89 03 603 and DE 91 03 817 such activating means with limit switches for adjusting furniture or furniture parts are known.
Ved anvendelse af disse aktiveringsorganer i bestemte anvendelsesområder som f.eks. pleje- og hospitalsområdet gælder særlige bestemmelser, som skal overholdes. Dertil hører især afbrydelsen af aktuatoren i endepositionerne, hvor det eksempelvis i tilfælde af en fejl eller et svigt af endestopafbryderen ikke må optræde nogen fare for brugeren.When using these actuators in particular applications such as e.g. the care and hospital area applies to special provisions that must be observed. In particular, there is the interruption of the actuator in the end positions, where, for example, in the event of a failure or failure of the limit switch, no danger to the user may occur.
For ved svigt af en endestopafbryder at opnå den krævede sikkerhed mod fare for brugeren er det kendt at tilvejebringe forskellige slags mekaniske endestop, som hindrer spindelmøtrikkens eller spindlens lineærbevægelse i endepositionerne.In the event of failure of an end stop switch to achieve the required safety against danger to the user, it is known to provide various kinds of mechanical end stops which prevent the linear movement of the spindle nut or spindle in the end positions.
Det er her en ulempe, at dimensioneringen af disse dele betydeligt forøger omfanget og vægten af en sådan aktuator, hvilket ugunstigt bevirker en forøget udgift til disse 2 DK 2003 00207 U3 dele og en forøgelse af montageomkostningerne.It is a disadvantage here that the sizing of these parts significantly increases the scope and weight of such an actuator, which disadvantageously increases the cost of these parts and increases the installation costs.
DE 37 33 781 Al beskriver et lineærdrev med planetgear og modsat beliggende endestopafbrydere, af hvilke den ene tjener som sikkerhedsendestopafbryder, især til vekselstrømsmotorer, på grund af deres specielle egenskaber. Herved er den bekostelige holder for endestopafbryderen, dens indstilling og aktivering uhensigtsmæssig.DE 37 33 781 A1 discloses a linear drive with planetary gears and opposite end-stop switches, one of which serves as a safety end-stop switch, especially for AC motors, because of their special characteristics. In this way, the expensive holder for the limit switch, its setting and activation is inappropriate.
Der kendes desuden udførelsesformer for drev med ekstra endestopafbrydere, hvor endestopafbryderne aktiveres med ekstra indretninger og udvekslingsanordninger, som f.eks. beskrevet i DE 37 39 465 Cl.Further, embodiments of drives with additional limit switches are known in which the limit switches are actuated with additional devices and exchange devices, such as e.g. described in DE 37 39 465 Cl.
Ved de kendte versioner er det en ulempe, at omkostningerne til ekstra dele, disses pladsbehov og indstillingsarbejde er omfattende og uøkonomisk.With the known versions, it is a disadvantage that the cost of extra parts, their space requirements and adjustment work is extensive and uneconomical.
Det er opfindelsens formål at tilvejebringe en aktuator af den indledningsvis angivne art, som til særlige sikkerhedsrelevante anvendelsesområder ikke længere har de ovenfor omtalte ulemper, og hvor dens omfang ikke eller kun i ringe grad ændres, og hvor samtidig en minimal ekstraudgift muliggør økonomiske fordele.It is an object of the invention to provide an actuator of the type mentioned initially, which for particular safety-relevant applications no longer has the disadvantages mentioned above, and where its extent does not or only slightly change, and at the same time a minimal additional expense enables economic benefits.
Dette formål opnås ifølge opfindelsen ved, at i det mindste en sikkerhedsendestopafbryder er anbragt ved eller tilknyttet en af endestopafbryderne, og at sikkerhedsendestopafbryderen og den ved denne anbragte eller tilknyttede endestopafbryder er således anbragt, den ene efter den anden, at sikkerhedsendestopafbryderen først kan aktiveres, når den foran denne værende endestopafbryder er passeret.This object is achieved according to the invention in that at least one safety end switch is disposed at or associated with one of the limit switches and the safety end switch and the positioned or associated end switch is thus arranged, one after the other, that the safety end switch can only be activated when the one in front of this end-stop switch is passed.
Fordelagtige videreudformninger for opfindelsen er angivet i underkravene.Advantageous embodiments of the invention are set forth in the subclaims.
Aktiveringsorganet ifølge opfindelsen har i den foretrukne udførelsesform en jævnstrømsmotor og udstyres med mindst en ekstra sikkerhedsendestopafbryder, som befinder sig i umiddelbar nærhed af endestopafbryderen, som er placeret ved en endeposition. I en foretrukket fordelagtig udførelsesform har sikkerhedsendestopafbryderen samme dimensioner som den allerede eksisterende endestopafbryder og er således let at anbringe, idet den i fremføringsretningen eksempelvis for 3 3DK 2003 00207 U3 spindelmøtrikken er placeret efter den respektive endestopafbryder. Også en forskudt anbringelse ved siden af hinanden er tænkelig.In the preferred embodiment, the actuator according to the invention has a direct current motor and is equipped with at least one additional safety end-stop switch located in the immediate vicinity of the end-stop switch located at an end position. In a preferred advantageous embodiment, the safety end-stop switch has the same dimensions as the pre-existing end-stop switch and is thus easy to place, since in the feeding direction, for example, for the 3 3DK 2003 00207 U3 the spindle nut is positioned after the respective end-stop switch. Also, a staggered placement next to each other is conceivable.
I tilfælde af en defekt endestopafbryder standses motoren ikke af denne. Spindelmøtrikken forskydes videre i fremføringsretningen og aktiverer derefter sikkerhedsendestopafbryderen, som standser motoren.In the event of a faulty limit switch, the motor will not be stopped. The spindle nut is further displaced in the feed direction and then activates the safety end stop switch which stops the motor.
I en yderligere udførelsesform er sikkerhedsendestopafbryderen forsynet med et kendt aktiveringsorgan, som eksempelvis i form af en flad tunge muliggør en sikker aktivering af sikkerhedsendestopafbryderen, også når spindelmøtrikkens aktiveringsfremspring er deformeret eller ødelagt. Her er det også muligt, at dette aktiveringsorsgan har et yderligere fremspring og/eller en slags rulle.In a further embodiment, the safety end stop switch is provided with a known actuating means which, for example in the form of a flat tongue, enables a safe activation of the safety end stop switch, even when the actuating protrusion of the spindle nut is deformed or broken. Here it is also possible that this activating organ has an additional protrusion and / or a type of roller.
I en yderligere udførelsesform kan sikkerhedsendestopafbryderen med sin trykstang og sit kontaktsystem være placeret sammen med den tilhørende endestopafbryder inde i et afbryderhus. Dette muliggør hensigtsmæssigt en pladsbesparelse .In a further embodiment, the safety end-stop switch with its push rod and its contact system can be located together with the associated end-stop switch inside a switch housing. This conveniently allows for a space saving.
Det foreslås endvidere at udstyre sikkerhedsafbryderen med et ødelæggeligt aktiverings- og/eller kontaktsystem, således at en yderligere anvendelse af aktiveringsorganet efter udløsning af sikkerhedsendestopafbryderen ikke længere er mulig.It is further proposed to equip the safety switch with a destructive actuation and / or contact system, so that further use of the actuator after release of the safety end switch is no longer possible.
Sikkerhedsendestopafbryderen er ved direkte afbrydelse af motorstrømmen, dvs. at motorstrømmen går via endesto-pafbryderkontakterne, elektrisk forbundet i serie med de eksisterende endestopafbrydere.The safety end stop switch is by direct interruption of the motor current, ie. the motor current passes through the end-stop switches, electrically connected in series with the existing end-stop switches.
Sikkerhedsendestopafbryderens kontaktsystem kan have en parallelforbundet diode. Dermed er en yderligere drift af aktiveringsorganet efter en defekt i den første endestopafbryder mulig.The safety end stop switch contact system may have a parallel connected diode. Thus, further operation of the actuator after a defect in the first limit switch is possible.
Herved er det fordelagtigt, at aktiveringsorganet er forsynet med en signalindretning, som ved en defekt endestopafbryder viser dette for brugeren, så snart signalindretningen passeres og sikkerhedsendestopafbryderen udløses.Hereby, it is advantageous for the actuator to be provided with a signal device which, in the case of a defective end stop switch, shows this to the user as soon as the signal device is passed and the safety end stop switch is released.
Det kan være hensigtsmæssigt ikke at parallelfor- 4 DK 2003 00207 U3 binde nogen diode med sikkerhedsendestopafbryderens kontaktsystem, da aktiveringsorganet derved efter udløsning af sikkerhedsendestopafbryderen ikke længere bliver brugbar, hvilket muliggør en særlig fordelagtig fejldiagnose for rettidig udskiftning af aktiveringsorganet.It may be advisable not to parallel any diode with the safety end switch switch's contact system, as the actuator thereby no longer becomes usable upon release of the safety end switch, enabling a particularly advantageous fault diagnosis for timely replacement of the actuator.
Herved opnås hensigtsmæssigt et højt sikkerhedsniveau med en minimal konstruktionsdelsanvendelse.Consequently, a high level of safety is conveniently achieved with a minimal design part use.
Det er fordelagtigt, at der i en yderligere udførelsesform findes et afbryderelement, eksempelvis en udefra indstikkelig eller i huset indsættelig trykknap, som er parallelforbundet med sikkerhedsendestopafbryderen og ved trykpåvirkning gør det muligt at føre aktiveringsorganet til sin nederste position.Advantageously, in a further embodiment, there is a switching element, for example an externally insertable or insertable pushbutton, which is connected in parallel with the safety endstop switch and by pressure actuation allows the actuator to be moved to its lower position.
Ved indirekte afbrydelse af motorstrømmen, dvs. hvor motorstrømmen ikke går via endestopafbryderkontakterne, sker den elektriske tilslutning af sikkerhedsendestopafbryderen til en eksisterende styreanordning.By indirect interruption of the motor current, ie. where the motor current does not pass through the limit switches, the electrical connection of the safety limit switch to an existing control device is made.
Det er ligeledes tænkeligt, at andre aktiveringssystemer, såsom f.eks. induktive og/eller kapacitive endestopafbrydere, kan anvendes.It is also conceivable that other activation systems, such as e.g. inductive and / or capacitive limit switches may be used.
Også ved et endestopafbrydersystem, som består af afbrydelser i ledere på printkort, såkaldte PCB-ledere, er en sikkerhedsendestopafbryder i form af en i forskydningsretningen efter den pågældende endestopafbryder liggende afbrydelse mulig.Also in an end-stop switch system, which consists of circuit breakers in PCB conductors, so-called PCB conductors, a safety end-stop switch in the form of a switch in the shear direction after the relevant end-stop switch is possible.
Opfindelsen vil i det følgende blive nærmere forklaret under henvisning til fig. 1-5 på tegningen, hvor fig. 1 viser et længdesnit gennem et eksempel på en lineær aktuator, fig. 2 en hensigtsmæssig endestopafbryder, fig. 3 et ledningsdiagram over en motor med endestopafbrydere, fig. 4 et ledningsdiagram ifølge fig. 3 med den anden endestopafbryder, og fig. 5 et ledningsdiagram ifølge fig. 3 i en yderligere udførelsesform.The invention will now be explained in more detail with reference to FIG. 1-5 of the drawing, in which FIG. 1 is a longitudinal section through an example of a linear actuator; FIG. 2 shows a suitable end-stop switch; FIG. 3 is a wiring diagram of a motor with limit switches; FIG. 4 shows a wiring diagram according to FIG. 3 with the second limit switch, and FIG. 5 is a wiring diagram according to FIG. 3 in a further embodiment.
I fig. 1 er vist en foretrukken udførelsesform for en aktuator. Den består af et føringsrør 18, hvori en gevind- 5 5DK 2003 00207 U3 spindel 4 er optaget ved hjælp af et leje 19. På spindlen 4 er anbragt en spindelraøtrik 5, hvorpå et forskydningsrør 17 er anbragt. Spindelmøtrikken 5 har fremspring 14 med aktiveringsflader 15, 16. Den er drejningsstift forskydeligt ført inde i føringsrøret 18, hvorved drejningsstivheden opnås ved hjælp af fremspring 14, der føres i parallelt med føringsrørets 18 midterakse forløbende udsparinger 20.In FIG. 1 is a preferred embodiment of an actuator. It consists of a guide tube 18 in which a threaded spindle 4 is received by means of a bearing 19. On the spindle 4 is a spindle rotor 5, on which a displacement tube 17 is arranged. The spindle nut 5 has projections 14 with actuating faces 15, 16. It is rotatably slidably inserted within guide tube 18, whereby the rotational stiffness is obtained by projections 14 which are guided in parallel with the central axis of recesses 20 of guide tube 18.
Spindlen 4 drives via et gears og en motors transmissionsudtag 3 på kendt måde i to forskellige drejningsretninger. Gear og motor er ikke vist. Her omsættes spindlens 4 drejningsbevægelse i en længdebevægelse for spindelmøtrikken 5 og det i føringsrøret 18 førte forskydningsrør 17.The spindle 4 is driven via a gear and an engine transmission outlet 3 in a known manner in two different directions of rotation. Gear and motor are not shown. Here, the rotational movement of the spindle 4 is translated into a longitudinal movement of the spindle nut 5 and the displacement tube 17 inserted in the guide tube 18.
I en yderligere udsparing 21 i føringsrøret 18 er anbragt endestopafbrydere 6, 7 og 11, hvis trykstang 12 aktiveres via aktiveringsfladerne 15, 16 på det herimod vendende fremspring 14 ved ankomsten til den pågældende endestopafbryder 6, 7 og 11. Endestopafbryderen 6 er placeret ved en nedre og endestopafbryderen 7 ved en derover liggende øvre position for aktiveringsorganet 1. Oven over endestopafbryderen 7 er endestopafbryderen 11 anbragt, som i dette arrangement danner en sikkerhedsendestopafbryder.In a further recess 21 in the guide tube 18, end-stop switches 6, 7 and 11 are arranged, the push rod 12 being actuated via the actuating faces 15, 16 on the opposite projection 14 upon arrival at the respective end-stop switch 6, 7 and 11. The end-stop switch 6 is located at a the lower and end stop switch 7 at an upper position of the actuator 1 above it. Above the end stop switch 7 is placed the end stop switch 11 which in this arrangement forms a safety end stop switch.
Ved indkøring eller indskydning af aktiveringsorganet 1 bevæger spindelmøtrikken 5 sig nedefter, dvs. i retning af lejet 19. Spindelmøtrikkens 5 fremsprings 14 aktiveringsflade 15 bevirker via sin skrå påløbsflade en bevægelse af den nedre endestopafbryders 6 trykstang 12, som afbryder strømtilførslen til drivmotoren (se desuden fig. 3-5), hvorved bevægelsen afbrydes.Upon insertion or insertion of the actuator 1, the spindle nut 5 moves downwards, i.e. in the direction of bearing 19. The actuating surface 15 of the spindle nut 5 protrudes via its inclined inlet surface a movement of the lower end stop switch 6 push rod 12, which interrupts the power supply to the drive motor (see also Figs. 3-5), thereby interrupting the movement.
Hvis endestopafbryderen 6 er defekt, sker der ingen afbrydelse af drivmotoren, og spindelmøtrikken 5 trækkes mod lejet 19, hvorved motoren blokeres og standser. Konstruktionsdelene er f.eks. konstruktionsmæssigt således anbragt, at der ikke sker nogen ødelæggelse. En udkøring eller udskydning af aktiveringsorganet er også fortsat mulig.If the limit switch 6 is defective, the drive motor is not interrupted and the spindle nut 5 is pulled against the bearing 19, thereby blocking and stopping the motor. The structural parts are e.g. arranged in such a manner that no destruction occurs. An extension or extension of the actuator is also still possible.
Det er tænkeligt, at der i et andet tilfælde kan ske en ødelæggelse af gearet, men dette udgør dog ingen fare for brugeren i denne aktiveringsorganposition, fordi en ud- 6 DK 2003 00207 U3 skydning af aktiveringsorganet eksempelvis med et defekt geartandhjul ikke længere er mulig. Således er på fordelagtig måde aktiveringsorganet efter denne såkaldte første fejl i sikker tilstand.It is conceivable that in another case there may be a destruction of the gear, but this does not, however, pose a danger to the user in this actuator position because, for example, a shooting of the actuator with a defective gear tooth is no longer possible. . Thus, advantageously after this so-called first failure, the actuating means is in safe condition.
Ved udkøring af aktiveringsorganet 1 bevæger spindelmøtrikken 5 sig opefter i retning mod den øvre endestopafbryder 7, som ved spindelmøtrikkens 5 fremsprings 14 aktiveringsflades 16 passage af sin trykstang 12 afbryder aktuato-rens bevægelse opefter. En defekt på denne øvre endestopaf-bryder 7 afbryder ikke kørebevægelsen, og spindelmøtrikken 5 bevæger sig derfor yderligere opefter. I det videre forløb af udkøringsbevægelsen kommer spindelmøtrikkens 5 fremsprings 14 aktiveringsflade 16 frem til endestopafbryderens 11 trykstang 12, som da hensigtsmæssigt som en sikkerhedsendestopafbryder afbryder aktiveringsorganets udkørings- eller udskydningsbevægelse .As the actuator 1 is extended, the spindle nut 5 moves upwards in the direction towards the upper end stop switch 7, which, when the actuating surface 16 of the spindle nut 5 protrudes 14, activates the actuator 12 from interrupting the actuator's movement upwards. A defect on this upper end stop switch 7 does not interrupt the travel movement and the spindle nut 5 therefore moves further upwards. In the further course of the run-out movement, the actuating surface 16 of the spindle nut 5 arrives at the push rod 12 of the end stop switch 11, which then conveniently interrupts the actuating movement of the actuating member or the push-out movement.
Sikkerhedsendestopafbryderen 11 er i en fordelagtig udførelsesform af samme type som endestopafbryderen 6, 7.The safety end stop switch 11 is in an advantageous embodiment of the same type as the end stop switch 6, 7.
I en yderligere udførelsesform, som vises fig. 5 og beskrives detaljeret nedenfor, er det ikke mere muligt manuelt at betjene aktuatoren til indkøring, hvilket viser sig at være særlig fordelagtigt til erkendelse af en defekt endestopafbryder 11.In a further embodiment shown in FIG. 5 and described in detail below, it is no longer possible to manually operate the actuator for run-in, which proves to be particularly advantageous for recognizing a faulty end-stop switch 11.
I en yderligere udførelsesform er sikkerhedsendestopafbryderen 11 udformet med en yderligere kendt aktiveringsorgan 13, som f.eks. har en langagtig flad form, som strækker sig over hele endestopafbryderens 11 længde og ligger an mod trykstangen 12 som vist i fig. 2. Aktiveringsorganet 13 er svingbart anbragt på endestopafbryderens 11 hus. Også yderligere former for aktiveringsorganer og andre trykstangsformer er tænkelige.In a further embodiment, the safety end stop switch 11 is formed with a further known actuator 13, such as e.g. has a longish flat shape which extends over the entire length of the limit switch 11 and abuts the push rod 12 as shown in FIG. 2. The actuator 13 is pivotally disposed on the housing of the limit switch 11. Further forms of actuators and other push rod forms are also conceivable.
Det er herved særligt fordelagtigt, at berøringsfladen mellem spindelmøtrikkens 5 fremsprings 14 aktiveringsflade 16 og endestopafbryderens 11 trykstang 12 ved hjælp af dette aktiveringsorgan 13 forøges betydeligt, navnlig når fremspringet 14 er deformeret af forudgående beskadigelse.It is hereby particularly advantageous that the contact surface between the actuating surface 16 of the spindle nut 5 and the pressing rod 12 of the end stop switch 11 by means of this actuating member 13 is significantly increased, especially when the projection 14 is deformed by prior damage.
7 7DK 2003 00207 U3 I tilfælde af et deformeret fremspring 14 er det særligt fordelagtigt, at endestopafbryderens 11 trykstang 12 henholdsvis aktiveringsorgan 13 er således udformet, at der sikres en sikker aktivering af endestopafbryderen 11, også ved en deformeret fremspring 14. Hertil kan f.eks. trykstangen 12 have en større længde og bredde. Det er også tænkeligt, at aktiveringsorganet 13 kan være udformet med et fremspring 22. Et ikke deformeret fremspring 14 på spindelmøtrikken 5 aktiverer sikkerhedsendestopafbryderen 11 med sin aktiveringsflade 16, som kontakter aktiveringsorganet 13 i indkøringsområdet. Hvis fremspringn 14 er deformeret eller ødelagt, aktiveres aktiveringsorganet 13 ved hjælp af sit fremspring 22 via spindelmøtrikkens 5 legeme eller af den ubeskadigede rest af fremspringn 14.7 7GB 2003 00207 U3 In the case of a deformed projection 14, it is particularly advantageous that the push rod 12 of the end-stop switch 11 or actuator 13, respectively, is designed to ensure a safe activation of the end-stop switch 11, even with a deformed projection 14. Hereby, eg. the push rod 12 has a greater length and width. It is also conceivable that the actuator 13 may be formed with a protrusion 22. A non-deformed protrusion 14 on the spindle nut 5 activates the safety end stop switch 11 with its actuating surface 16 which contacts the actuator 13 in the run-in area. If the protrusion 14 is deformed or broken, the actuator 13 is activated by its protrusion 22 via the body of the spindle nut 5 or by the undamaged remainder of the protrusion 14.
Fig. 3 viser et kendt ledningsdiagram for en motor 2, som fortrinsvis er en jævnstrømsmotor, og som er vist med de to endestopafbrydere 6, 7, som her er vist som afbrydersymboler. De er indsat efter hinanden i motorledningen og shuntet via en ensretter, en såkaldt diode 8, 9. Dioderne 8, 9 er modsat forbundet i serie, dvs. at ved to samtidigt åbne eller manglende endestopafbrydere 6, 7 kan der ikke gå nogen strøm, uafhængigt af polariteten for en strømforsynings-jævnstrømsspændings UDC ved tilslutningerne A og B.FIG. 3 shows a known wiring diagram of a motor 2, which is preferably a direct current motor, and which is shown with the two limit switches 6, 7, which are shown here as switch symbols. They are inserted one after another in the motor line and shunted via a rectifier, a so-called diode 8, 9. The diodes 8, 9 are opposite in series, ie. that at two simultaneously open or missing limit switches 6, 7 no current can flow, regardless of the polarity of a DC power supply UDC at terminals A and B.
Hvis aktiveringsorganet 1 befinder sig mellem den øvre og nedre position, er begge endestopafbrydere 6, 7 sluttet. Denne tilstand kan udledes af fig. 3. Polariteten for jævnspændingen UDC ved A og B bestemmer motorens 2 omdrejningsretning og således aktiveringsorganets 1 bevægelsesretning. Motoren 2 kan blive tilsluttet i begge omdrejningsretninger, for strømmen går såvel via dioderne 8, 9 som via endestopafbryderne 6, 7: til udkøring eller udskydning ligger jævnspændingens pluspol ved punktet A. Strømmen går således fra A via motoren 2 gennem dioden 8, som danner en herfor åben ensretterventil, og den sluttede endestopafbryder 6 videre gennem den sluttede endestopafbryder 7 til punktet B. Dioden 9 virker herved som en spærreventil.If the actuator 1 is located between the upper and lower positions, both limit switches 6, 7 are closed. This state can be deduced from FIG. 3. The polarity of the DC voltage UDC at A and B determines the direction of rotation of the motor 2 and thus the direction of movement of the actuator 1. The motor 2 can be connected in both directions of rotation, for the current goes through both diodes 8, 9 and via the limit switches 6, 7: for output or extension, the positive voltage of the DC voltage is at point A. The current thus goes from A via motor 2 through diode 8, which forms a rectifier valve open thereto, and the closed limit switch 6 continues on through the closed limit switch 7 to the point B. The diode 9 thus acts as a shut-off valve.
Ved aktivering af endestopafbryderen 7 i den øvre 8 DK 2003 00207 U3 position åbner denne sin kontakt, og motoren 2 afbrydes, fordi strømforsyningen afbrydes. En viderekørsel i denne retning er ikke længere mulig.When activating the limit switch 7 in the upper 8 position, this opens its contact and the motor 2 is switched off because the power supply is switched off. A drive in this direction is no longer possible.
Ved indkøring af aktiveringsorganet 1 ligger jævnspændingens UDC pluspol ved punktet B. Hvis aktiveringsorganet 1 befinder sig i den øvre stilling, går strømmen nu via dioden 9 og den sluttede endestopafbryder 5 gennem motoren 2 til punktet A, hvor i dette tilfælde dioden 8 virker som spærreventil .When the actuator 1 is run in, the DC voltage UDC plus pole is at the point B. If the actuator 1 is in the upper position, the current now passes through the diode 9 and the closed end switch 5 through the motor 2 to the point A, in which case the diode 8 acts as a shut-off valve. .
Ved aktivering af endestopafbryderen 6 i den nedre position sker den samme proces som beskrevet ovenfor for endestopafbryderen 7, ligeledes ved udkøring af aktiveringsorganet 1 fra den nedre position.When activating the limit switch 6 in the lower position, the same process as described above for the limit switch 7 also occurs, as well as by activating the actuator 1 from the lower position.
I fig. 4 er sikkerhedsendestopafbryderen 11 indsat i endestopafbryderens 6, 7 serieforbindelse. Med afbryderen 11 er parallelforbundet en diode 10, hvis ensretteregenskab har samme opgave som den øvre endestopafbryders 7 diode 9.In FIG. 4, the safety end-stop switch 11 is inserted into the serial connection of the end-stop switch 6, 7. With the switch 11, a diode 10 is connected in parallel, the rectifier having the same function as the upper limit switch 7 diode 9.
Beskrivelsen af enkeltdelene fremgår af beskrivelsen til fig. 3.The description of the individual parts is shown in the description of FIG. Third
Sikkerhedsendestopafbryderen 11 virker som en redundant konstruktionsdel for den øvre endestopafbryder 7. Hvis den øvre endestopafbryder 7 er defekt, idet f.eks. dens kontakt ikke mere kan åbnes, da bliver den passeret og sikkerhedsendestopafbryderen 11 aktiveres. Dens kontakt afbryder strømforsyningen til motoren 2, og aktuatoren bliver standset. En bevægelse af aktiveringsorganet 1 i modsat retning er mulig, fordi dioden 10 derved virker som åben ensretterventil ligesom dioden 9 bekrevet under fig. 3. Herved kan det imidlertid ikke fastslås udefra, om der foreligger en endesto-pafbryderdefekt.The safety end stop switch 11 acts as a redundant structural member for the upper end stop switch 7. If the upper end stop switch 7 is defective, e.g. its contact can no longer be opened, then it is passed and the safety end switch 11 is activated. Its contact switches off the power supply to the motor 2 and the actuator is stopped. A movement of the actuator 1 in the opposite direction is possible because the diode 10 thereby acts as an open rectifier valve like the diode 9 described in FIG. 3. However, it cannot be determined from the outside whether there is an end-stop switch defect.
Derved er det fordelagtigt, at aktiveringsorganet er forsynet med et signalelement 23, som ved en defekt endestopafbryder 6, 7 kan vise dette for brugeren, så snart afbryderen passeres og sikkerhedsendestopafbryderen 11 udløses. Et sådant signalelement 23 kan være et akustisk eller optisk signalorgan, som befinder sig i aktiveringsorganet 1 og/eller i styreanordningen.Thereby, it is advantageous for the actuator to be provided with a signal element 23 which, in case of a faulty end-stop switch 6, 7, can show this to the user as soon as the switch is passed and the safety end-stop switch 11 is released. Such a signal element 23 may be an acoustic or optical signal means located in the actuator 1 and / or in the control device.
9 9DK 2003 00207 U3 I udførelsesformen ifølge fig. 5 viser denne et kredsløb ifølge fig. 4, dog uden dioden 10. Herved er det i en fordelagtig udførelsesform mulig, at aktiveringsorganet 1 efter aktivering af endestopafbryderen 11 ikke mere er funktionsdygtigt. Endestopafbryderen 11 anvendes således som en sikkerhedsendestopafbryder. Det kan således hensigtsmæssigt erkendes, når der på grund af en endestopafbryderdefekt foreligger en fejl.9 9GB 2003 00207 U3 In the embodiment of FIG. 5, this shows a circuit according to FIG. 4, but without the diode 10. Hereby, in an advantageous embodiment, it is possible that the actuating means 1 after activation of the limit switch 11 is no longer operable. The end-stop switch 11 is thus used as a safety end-stop switch. Thus, it can conveniently be recognized when there is an error due to an end-stop switch defect.
Det er fordelagtigt, at der i en videre udførelsesform er indsat et omskifterelement 24, som f.eks. kan indstikkes udefra eller er anbragt i huset, og som er indskudt i parallel forbindelse med sikkerhedsendestopafbryderen 11 og muliggør bevægelse af aktiveringsorganet 1 til den nederste position. En diode 25 har til opgave kun at tillade en kørsel til den nedre position.Advantageously, in a further embodiment, a switching element 24, such as e.g. may be inserted from the outside or arranged in the housing, which is inserted in parallel with the safety end switch 11 and allows movement of the actuator 1 to the lower position. The purpose of a diode 25 is to allow only one drive to the lower position.
Ligeledes er i denne udførelsesform et yderligere signalelement 23 muligt.Also, in this embodiment, a further signal element 23 is possible.
Omskiftereksemplerne ifølge fig. 3-5 viser endestopafbrydere 6, 7, 11, hvis kontaktsæt gennemstrømmes direkte af motorstrøm. Det er ligeledes muligt, at endestopafbryderne 6, 7, 11 indirekte afbryder motoren 2 via omskifterforstær kere, såsom f.eks. effekthalvledere eller relæer.The switch examples of FIG. 3-5 show end-stop switches 6, 7, 11, whose contact sets are flowed directly by motor current. It is also possible that the limit switches 6, 7, 11 indirectly switch off the motor 2 via switch amplifiers, such as e.g. power semiconductors or relays.
Sikkerhedsendestopafbryderen 11 kan være udformet som en yderligere konstruktionsdel af kendt udførelse eller som et yderligere kontaktsystem i et fælles hus, eksempelvis sammen med endestopafbryderen 7. Derved er det også muligt, at sikkerhedsendestopafbryderen 11 og endestopafbryderen 7 kan være anbragt forsat ved siden af hinanden. Sikkerhedsendestopafbryderen 11 kan også være udført som en enkel trådbøjle, som ødelægges ved aktivering og derved afbryder strømforsyningen til motoren 2.The safety end-stop switch 11 may be designed as a further structural part of known design or as a further contact system in a common housing, for example together with the end-stop switch 7. It is also possible that the safety end-stop switch 11 and the end-stop switch 7 can be arranged side by side. The safety end stop switch 11 may also be designed as a simple wire brace, which is damaged by activation, thereby interrupting the power supply to the motor 2.
Det er ligeledes muligt, at endestopafbryderne 6 og 7 kan være udformet som afbrydelsessteder for en eller flere PCB-ledere, hvorved sikkerhedsendestopafbryderen 11 danner et ekstra afbrydelsessted i udkøringsretningen efter eller foran det pågældende endestopafbryder-afbrydelsessted.It is also possible that the end-stop switches 6 and 7 may be designed as switching points for one or more PCB conductors, whereby the safety end-switch switch 11 forms an additional switching point in the exit direction after or in front of the relevant end-switch switching point.
Endestopafbryderen 6, 7, 11 kan naturligvis også 10 DK 2003 00207 U3 bestå af andre omskiftersystemer, såsom f.eks. berøringsløse kontakter.Of course, the limit switch 6, 7, 11 may also consist of other switching systems, such as e.g. contactless contacts.
Det er endvidere muligt at forsyne såvel den øvre endestopafbryder 7 som den nedre endestopafbryder 6 med en sikkerhedsendestopafbryder 11.Furthermore, it is possible to provide both the upper limit switch 7 and the lower limit switch 6 with a safety end switch 11.
Den foreliggende endestopafbryderkombination er ikke begrænset til de viste udførelseseksempler. Det kan også anvendes ved aktiveringsorganer, hvis spindel f.eks. forskydes aksialt og har egnede knaster til endestopafbryderaktivering. Også såkaldte rotationsaktiveringsorganer, som med en rotationsbevægelse bevirker en indstilling af et møbel og er udstyret med endestopafbrydere, kan være udstyret med sikkerhedsendestopafbrydere .The present end-stop switch combination is not limited to the exemplary embodiments shown. It can also be used with actuators whose spindle e.g. are displaced axially and have suitable end stop switch actuation knobs. Also so-called rotary actuators which, with a rotary motion, cause an adjustment of a piece of furniture and are equipped with end-stop switches, may be equipped with safety end-stop switches.
