Description

8401296-2 drivhjulet vända yta är likformig med dettas periferiyta, vilket bagelement är styrt av nämnda styrdon pa ett sadant sätt att det för att öka bandhastigheten hos ett eftersläpande transportband, bringas till operativ förbindelse med drivhjulets periferiyta och får följa med i drivhjulets rotationsrörelse, vilket är liktydigt med en temporär ökning av hjulets diameter, men i övrigt bringas ur ingrepp med drivhjulets periferi och vilar i en punkt utefter den del av hjulets periferi som ej är i kontakt med transportbandet. The turning surface of the drive wheel is uniform with its peripheral surface, which rear element is controlled by said guide means in such a way that in order to increase the belt speed of a lagging conveyor belt, it is brought into operative connection with the peripheral surface of the drive wheel and allowed to follow the rotational movement of the drive wheel. is tantamount to a temporary increase in the diameter of the wheel, but is otherwise disengaged from the periphery of the drive wheel and rests at a point along the part of the periphery of the wheel which is not in contact with the conveyor belt.

Enligt ett föredraget utförande innefattar anordningen enligt- uppfinningen en elektro- magnet inrättad att mot verkan av en fjäder bringa bagelementet ur ingrepp med drivhjulets periferi, vilken fjäder är inrättad att bringa bagelementet till operativ förbindelse med drivhjulets periferí.According to a preferred embodiment, the device according to the invention comprises an electromagnet arranged to, against the action of a spring, bring the bag element out of engagement with the periphery of the drive wheel, which spring is arranged to bring the bag element into operative connection with the periphery of the drive wheel.

För att korrigeringen av bandhastigheten skall ske sa jämnt som möjligt avsmalnar bagelementets ändar kilformigt, sa som framgar av ännu ett särskilt kännetecken för uppfinningen.In order for the correction of the belt speed to take place as evenly as possible, the ends of the bag element taper wedge-shaped, as is apparent from yet another special feature of the invention.

Uppfinningen skall i det följande förklaras närmare i anslutning till bifogade ritning som visar uppfinningen tillämpad vid en taktegeihiss. Pa ritningen visar fig l schematiskti perspektiv hissens lastningsstation dvs den plats där takteglet lastas pa banden. Fig 2 visar i en vy snett bakifrån i detalj en drivmotor med tvenrie drivhjul och pa ett av dessa ett utförande av en anordning enligt uppfinningen.The invention will be explained in more detail below in connection with the accompanying drawing which shows the invention applied to a roof tile elevator. In the drawing, Fig. 1 schematically shows the loading station of the elevator, ie the place where the roof tile is loaded on the belts. Fig. 2 shows in a view obliquely from behind a drive motor with two drive wheels and on one of these an embodiment of a device according to the invention.

Pa ritningen betecknar 1 och 2 tvenne materialtransportband vilka löper parallellt bredvid varandra mellan var sitt hjulpar anordnade i bandens resp ändar. Av dessa visas pa ritningen endast de som drivhjul 3 resp 4 verkande hjulen, vilka via en växellåda 5 drivs av en gemensam drivmotor 6, företrädesvis en elmotor. De återstående två hjulen i bandens l, 2 andra ändar tjänar som brythjul för banden l, 2. Nu nämnda delar, där hjulen 3, 4, växel 5 och elmotorn 6 företrädesvis är sammanbyggda till en enhet 9, är anordnade pa en av hjul 7 uppburen stomme 8 sa att taktegelhissen lätt kan transporteras dragen av t ex en lastbil Främre delen av enhetens 9 ovansida är utformad som en palastningsstation för det material, i detta fall taktegel lÛ, som skal] transporteras med hjälp av banden 1, 2. I palastningsstationen placeras materialet pa skenor ll och pa banden l, 2 finns medbringare 12 inrättade att skjuta materialet av dessa skenor sa att det slutligen uppbäres helt av banden 1, 2. För att understödja dessa finns utefter banden mellan driv- och brythjulen anordnade stödrullar 13, av vilka endast tva visar pa ritningen. 8401296-2 Som nämnts inledningsvis kan det av olika skäl inträffa att banden 1, 2 ej löper synkront. Detta medför att materialet pa banden tenderar att vrida sig i horisontel- planet och kan resultera i att materialet faller ned fran banden. För att förhindra att banden drar olika finns dels organ inrättade att detektera en viss punkt pa resp band och att alstra en signal da nämnda punkt kommit frarri till nämnda detektororgans känslighetszon, dels ett med detekteringsorganen förbundet styrdon 14 och dela med styrdonet 14 förbundna korrigeringsorgari 15 inrättade att ternporärt minska bandhastig- heten hos det ledande bandet eller alternativt temporärt öka bandhastigheten hos det eftersläpande bandet. Vilken av nämnda styralternativ som används kan variera beroende pa vilket slag av transport som skall utföras. Likasa kan detekteringen utföras pa manga olika sätt, mekaniskt med sk gränslägesbrytare, optiskt med hjälp av fotoceller eller, som i det pa ritningen visade fallet, medelst inbördes ekvidistant pa banden anordnade magneter 16 och för iriagnetfält känsliga detektororgan 17 exempelvis s k tungreläer, vilka rent praktiskt är lokaliserade i anslutning till stödrullarna 13 pa enheten 9 men ej är synliga i fig 1.In the drawing, 1 and 2 denote two material conveyor belts which run parallel next to each other between respective pairs of wheels arranged in the respective ends of the belts. Of these, only the wheels acting as drive wheels 3 and 4, respectively, are shown in the drawing, which are driven via a gearbox 5 by a common drive motor 6, preferably an electric motor. The remaining two wheels at the other ends of the belts 1, 2 serve as break wheels for the belts 1, 2. Now mentioned parts, where the wheels 3, 4, gear 5 and the electric motor 6 are preferably assembled into a unit 9, are arranged on one of wheels 7 supported frame 8 said that the roof tile lift can be easily transported pulled by, for example, a truck. The front part of the upper part of the unit 9 is designed as a loading station for the material, in this case roof tile lÛ, which is to be transported by means of belts 1, 2. the material is placed on rails l1 and on the belts 1, 2 there are carriers 12 arranged to push the material of these rails so that it is finally fully supported by the belts 1, 2. To support these there are support rollers 13 arranged along the belts between the drive and break wheels. which only two show in the drawing. 8401296-2 As mentioned in the introduction, it can happen for various reasons that belts 1, 2 do not run synchronously. This means that the material on the belts tends to rotate in the horizontal plane and can result in the material falling off the belts. In order to prevent the belts from pulling differently, means are provided for detecting a certain point on each belt and for generating a signal when said point has reached the sensitivity zone of said detector means, and for a control device 14 connected to the detection means and for dividing means connected to the control means 14. to temporarily reduce the belt speed of the conductive belt or alternatively temporarily increase the belt speed of the lagging belt. Which of the said control options is used may vary depending on the type of transport to be performed. Likewise, the detection can be performed in many different ways, mechanically with so-called limit switches, optically by means of photocells or, as in the case shown in the drawing, by means of mutually equidistantly arranged magnets 16 and for field-sensitive detector means 17, for example so-called heavy relays. are located adjacent to the support rollers 13 on the unit 9 but are not visible in Fig. 1.

Styrningen kan utföras efter manga olika principer. Sa kan man exempelvis se till att ett av banden normalt gar nagot fortare än det andra och sa länge det med tillhörande detektororgan konstateras att bandet _leder över det andra bandet minskas dess hastighet temporärt. Alternativt ökas hastigheten ternporärt hos det eftersläpande bandet tills det med nämnda detektororgan konstaterats 'att det normalt ledande bandet i själva verket är det eftersläpande. Enligt ytterligare en styrprincip utgar man ifran att banden löper med lika hastighet. Om man konstaterar att det ena bandet leder över det andra minskas dettas hastighet alternativt ökas det eftersläpanoe bandets hastighet temporärt tills det omvända förhållandet rader.The control can be performed according to many different principles. For example, one can ensure that one of the belts normally runs somewhat faster than the other, and as long as it is established with the associated detector means that the belt leads over the other belt, its speed is temporarily reduced. Alternatively, the velocity of the lagging band is increased until it is established with said detector means that the normally conductive band is in fact the lagging band. According to another guiding principle, it is assumed that the belts run at the same speed. If it is found that one belt leads over the other, its speed is reduced or the speed of the lagging belt is temporarily increased until the inverse ratio lines.

Det finns för fackmannen ytterligare kända styrprinciper for vilka ej skall redogöras här.There are further known guiding principles for those skilled in the art, which will not be described here.

Enligt uppfinningen innefattar nämnda korrigeringsorgaii 15 ett vid resp drivhjul 3, 4 anordnat bagelement 18, vars bredd är minst lika stor som drivhjulets 3, 4 bredd, vars tjocklek är en brakdel av drivhjulets diameter och vars mot drivhjulets vända yta är likformig med dettas periferiyta. Bagelementet 18 är lagrat pa ett sadant sätt att det dels under inverkan av en fjäder 19 bringas till ingrepp med hjulets periferiyta, dels under inverkan av en elektromagnet 20 och mot fjäderns 19 verkan, bringas ur ingrepp med nämnda periferiyta. Lagringen utgöres av en vinkelfnrinaci länkarrn 21 som är fritt roterbart lagrad relativt axeln 22 av resp drivhjul i, li. Pa lánkarmen 21 finns ett koaxiellt med elektromagneten 20 anordnat ok 23. 8401296-2 Korrigeringsorganet enligt uppfinningen arbetar på följande sätt, varvid det antages att transportbandet 2 släpar efter relativt transportbandet 1: Under inverkan av elektro- magneten 2D som strömmatas från styrdonet 14 och attraherar oket 23, bringas bagelementet 18 ur ingrepp med drivhjulet 4 mot verkan av fjädern _19 och vilar i en punkt utefter drivhjulets 4 periferi, som ej är i kontakt med bandet 2. Genom signal fran detektororganen l7:l och 17:2 konstateras att bandet 2 leder över bandet 1 vilket medför att strömmatningen till elektromagneten upphör. Under inverkan av fjädern 19 bringas bägelementet 18 till ingrepp 'med drivhjulets 4 periferiyta och följer med detta runt under hjulets rotation. Effekten härav blir en något ííkad omkrets hos drivhjulet 4, vilket i sin tur få till följd en nagot ökad handliazitiqher varigenom bandets 2 irflvrsläpriixwg korrigorus. Det insus att. genom al! anordna :styrdonot 14 på lämpligt sätt kan med uppfinningen åstadkommas vilket som helstruv de ovan beskrivna styralterna- tiven.According to the invention, said correction member 15 comprises a bag element 18 arranged at respective drive wheels 3, 4, the width of which is at least equal to the width of the drive wheel 3, 4, the thickness of which is a fraction of the diameter of the drive wheel and whose surface facing the drive wheel is uniform. The bag element 18 is stored in such a way that under the action of a spring 19 it is brought into engagement with the peripheral surface of the wheel, partly under the influence of an electromagnet 20 and against the action of the spring 19, it is brought out of engagement with said peripheral surface. The bearing consists of an angular rotation of the link arm 21 which is freely rotatably mounted relative to the shaft 22 of the respective drive wheels i, li. On the link arm 21 there is a yoke arranged coaxially with the electromagnet 20. The correcting means according to the invention operates in the following manner, it being assumed that the conveyor belt 2 lags behind the conveyor belt 1: Under the influence of the electromagnet 2D which is fed from the control device 14 and attracts yoke 23, the bag element 18 is brought out of engagement with the drive wheel 4 against the action of the spring 19 and rests at a point along the periphery of the drive wheel 4, which is not in contact with the belt 2. leads over the band 1 which causes the current supply to the electromagnet to cease. Under the action of the spring 19, the cup element 18 is brought into engagement with the peripheral surface of the drive wheel 4 and follows it around during the rotation of the wheel. The effect of this is a somewhat similar circumference of the drive wheel 4, which in turn results in a slightly increased handliazitiqher whereby the belt 2 irflvrsläpriixwg corrigorus. It insus that. through al! arrange: the control donor 14 can be achieved in a suitable manner with the invention, which as a whole ruins the control alternatives described above.

För att bàgelementet 18 ej skall ge upphov till ojämn gäng avsmalnar dess ändar kilformigt och för att bågeleineritet skall få ett säkert ingrepp med hjulets periferiyta har den mot nämnda yta vända ytan hos bågelemeritet en friktionsökande ytstruktur.In order that the arch element 18 does not give rise to uneven threads, its ends taper wedge-shaped and in order for the arch linearity to have a secure engagement with the peripheral surface of the wheel, the surface of the arch element facing said surface has a friction-increasing surface structure.

Uppfínningen få ej anses begränsad till den visade och beskrivna utföringsformenfutan kan inom ramen för uppfinningstanken modifieras på inanga sätt vad beträffar bade uppbyggnad och anvšintlriing.The invention may not be considered limited to the embodiment shown and described, but within the scope of the inventive concept the modifier may be modified in any way with respect to both construction and use.
