Description

Drivanordning for et endeløst transportbånd Drive device for an endless conveyor belt

ved et dokumenttransportanlegg. at a document transport facility.

Oppfinnelsen angår en drivanordning for et endelost transportbånd ved et dokumenttransportanlegg, der båndet i et område er fort ut fra banen i en sloyfe og ved hjelp av en strekkbelastet spenn- The invention relates to a drive device for an endless conveyor belt at a document transport facility, where the belt in an area is fast out of the path in a sloyfe and by means of a tension-loaded tension

rulle er holdt under spenning. Drivanordninger av denne art arbeider på en slik måte atNtransport-båndet for transport av transportbeholdere ledes over en lVderulle, som er drevet. Den nodvendigé spenning frembringes ved en spennrulle foran eller bak lederullen, nemlig under innvirkning av\vekter. Da transportbåndet toyes ut i lopet av sin anvendelsestid, må der roll is kept under tension. Drive devices of this kind work in such a way that the conveyor belt for the transport of transport containers is guided over a lV roller, which is driven. The necessary tension is produced by a tension roller in front of or behind the guide roller, namely under the influence of weights. As the conveyor belt wears out over the course of its useful life, there must

opprettholdes en stor fjærvei, som på sin side krever en forholdsvis stor byggehbyde. a large suspension road is maintained, which in turn requires a relatively large construction height.

Ofte innbygges drivanordningene for transportbåndene i mellomtak i bygninger, hvorved byggehoyden blir for stor, og det kreves kostbare konstruktive endringer for å tilveiebringe den nodvendige plass. Oppfinnelsen har til oppgave å tilveiebringe en langstrakt og "flat" fo rm for drivanordninger. Dette oppnås ved at sloyfen er fort over en drevet lederulle på en strekning som forloper omtrent parallelt med transportretningen og nedenfor denne, og at den strekkbelastede spennrullen angriper i sloyfen ved enden av den nedenfor forlbpende strekning. I detalj kan anordningen være således utformet at spennrullen er lagret i et stativ, som .er lengdeforskyvbart parallelt med transportretningen. Often, the drive devices for the conveyor belts are built into intermediate ceilings in buildings, whereby the building height becomes too large, and expensive constructive changes are required to provide the necessary space. The invention has the task of providing an elongated and "flat" form for drive devices. This is achieved by the loop being quickly over a driven guide roller on a section that runs approximately parallel to the direction of transport and below this, and that the tension-loaded tension roller attacks the loop at the end of the section running below. In detail, the device can be designed in such a way that the tension roller is stored in a stand, which is longitudinally displaceable parallel to the direction of transport.

På tegningen er drivanordningen ifolge oppfinnelsen anskueliggjort ved et skjematisk vist utforelseseksempel. I dette eksempel betegnes transportbåndet med 1, drivmotoren med 9, transportbånd-slbyfen med 10 og spennrullen med 7«In the drawing, the drive device according to the invention is illustrated by a schematically shown embodiment example. In this example, the conveyor belt is denoted by 1, the drive motor by 9, the conveyor belt pulley by 10 and the tension roller by 7"

Transportbåndet lbper i den ovre del av tegningen i et plan i den The conveyor belt runs in the upper part of the drawing in a plane in it

ene eller annen retning. Transportbåndet er over lederuller 2 og 3 fort nedover og danner i dette området sloyfen 10. Ytterligere lederuller 5, 6, 7j 4 innenfor og utenfor transportbåndet gir sloyfen 10 den onskede retning. one direction or another. The conveyor belt is over guide rollers 2 and 3 quickly downwards and in this area forms the loop 10. Further guide rollers 5, 6, 7j 4 inside and outside the conveyor belt give the loop 10 the desired direction.

Ved enden av sloyfen 10 leder lederullen 7 transportbåndet tilbake tii sin utgangsbane. Denne lederulle 7 utgjor samtidig spennrullen, som holder det endelose transportbånd i hele dets lengde under spenning. For dette formål er spennrullen 7 lagret i et stativ 11, som er lengdeforskyvbart i sidestyringer parallelt med transportstrekningen. Ved sin fra lederullen vendte side står stativet 11 under innvirkning av en på tegningen ikke vist fjær, som soker å forflytte stativet 11 i retning av pilen 8. Istedenfor en eneste fjær kan man også la flere fjærer angripe på stativet 11. At the end of the loop 10, the guide roller 7 guides the conveyor belt back to its exit path. This guide roller 7 also forms the tension roller, which keeps the endless conveyor belt under tension along its entire length. For this purpose, the tension roller 7 is stored in a stand 11, which is longitudinally displaceable in lateral guides parallel to the transport route. On its side facing away from the conductor roll, the stand 11 is under the influence of a spring not shown in the drawing, which seeks to move the stand 11 in the direction of the arrow 8. Instead of a single spring, several springs can also be applied to the stand 11.
