Abstract

This invention relates to a roller arrangement for feeding a material roll in an industrial machine forwards, preferably a roll in a cellulose or paper industry machine, the roller arrangement having such a design that it does not only feed the roll forwards but can also control the same laterally. According to the invention, the roller arrangement is characterized by the combination of the following features: a transverse roller (1), which is driven, is intended to be in contact with the material roll on its underside for feeding the same forwards, the roller having a width which is at least as great as the width of the roll; the roller (1) is intended to cooperate with contact means (3), which are arranged on the topside of the roll and are borne by a horizontal girder (4), which is arranged over and essentially parallel with the roller (1), the contact means having the purpose to force the roll against the roller; guide means (14-16) are suspended in the girder (4) and are intended to be in contact with the roll (2), the guide means (14-16) being arranged in that way that they can lift the girder (4) and by that the contact means (3) in order thereafter to be able to control the roll laterally.

Description

15 20 25 30 505 604 2 kontaktorgan i form av valsorgan med en sådan bredd att varje valsorgan skulle rymmas inom sektionen ifråga. Contact means in the form of roll means with such a width that each roll means would be accommodated within the section in question.

Den mittre sektionen 9 uppvisar också hjulorgan 14-16, som enligt denna utföringsform är tre till antalet. Naturligtvis kan antalet hjulorgan vara armorlunda och kan variera från tvâ och uppåt. Vart och ett av dessa hjulorgan 14-16 är roterbart lagrat på en (ej visad) horisontell axel och är avsett att fungera som styrorgan för massabanan, vilken i vissa lägen skall underkastas styrning i sidled.The middle section 9 also has wheel members 14-16, which according to this embodiment are three in number. Of course, the number of wheel members can be armor-like and can vary from two and up. Each of these wheel members 14-16 is rotatably mounted on a horizontal shaft (not shown) and is intended to function as a guide means for the pulp web, which in certain positions is to be subjected to lateral steering.

För detta ändamål finns en styrcylinder 17, som innefattar en kolv 18, vilken är rörlig fram och åter på hydraulisk, pneumatisk eller elektrisk väg i en riktning, som är väsentligen parallell med den horisontella balkens 4 längdriktning. Kolvorganets 18 yttre ände år ihopkopplad med ett ramparti 19, som är fastsatt vid det första styrhjulorganet 14 och uppvisar en del 20, som skjuter ut ett stycke från hjulorganet 14. Rampartiet 19 innefattar en övre del 21, som skjuter upp ovanför hjulorganet 14.For this purpose there is a guide cylinder 17, which comprises a piston 18, which is movable back and forth on hydraulic, pneumatic or electric path in a direction which is substantially parallel to the longitudinal direction of the horizontal beam 4. The outer end of the piston member 18 is connected to a frame portion 19, which is attached to the first guide wheel member 14 and has a portion 20 projecting a distance from the wheel member 14. The frame portion 19 includes an upper portion 21 projecting above the wheel member 14.

Den övre delen 21 är fastsatt i ett undre parti av en vertikal axel 22a, vars övre del är vridbart fastsatt i den horisontella, tvärgâende balken 4. På samma sätt samverkar de tvâ övriga styrhjulsorganen 15, 16 med var sitt ramparti 23, 24, vars utskjutande delar 25, 26 är sarnrnanbundna med det första rampartiets 19 yttre del 20.The upper part 21 is fixed in a lower part of a vertical shaft 22a, the upper part of which is rotatably fixed in the horizontal, transverse beam 4. In the same way the two other steering wheel members 15, 16 cooperate with their respective frame part 23, 24, the projecting parts 25, 26 are connected to the outer part 20 of the first frame portion 19.

Genom kolvcylinderns 17, 18 inverkan är det sålunda möjligt att vrida de tre styrhjulsorganen 14-16 fram och tillbaka såsom indikeras med de tre pilama 27a,b,c.By the action of the piston cylinder 17, 18 it is thus possible to turn the three steering wheel members 14-16 back and forth as indicated by the three arrows 27a, b, c.

Såsom tidigare nämnts finns ett stort antal kontaktorgan i förrn av kontakthjul 3, vilka ligger an mot massabanan 2 för att pressa denna mot den drivande valsen 1. ~ Detta innebär att så länge dessa kontakthjul 3 ligger an mot massabanan 2 och därigenom mot den drivande valsen 1 så kommer icke massabanan att röra sig i sidled vid vridning av styrhjulorganen 14-16, utan massabanan kommer först att svara på rörelsen från styrhjulen, då kontakthjulen genom upplyftning släpper kontakten med massabanan.As previously mentioned, there are a large number of contact means in front of contact wheels 3, which abut against the pulp web 2 to press it against the driving roller 1. This means that as long as these contact wheels 3 abut against the pulp web 2 and thereby against the driving roller 1, the pulp web will not move laterally when the guide wheel means 14-16 are rotated, but the pulp web will first respond to the movement from the guide wheels, when the contact wheels release the contact with the pulp web by lifting.

I fig. 2, som visar ett längsgående snitt genom den horisontella balken 4 och styrhjulen 14-16, visas hur den nya uppfinningen är konstruerad för att lösa det nämnda problemet.Fig. 2, which shows a longitudinal section through the horizontal beam 4 and the guide wheels 14-16, shows how the new invention is designed to solve the said problem.

Styrhjulen 14-16 är som tidigare nämnts roterbart anordnade i var sitt ramparti 19, 23, 24. Detta ramparti uppvisar en övre del 21, som är fastsatt i undre delen 25 av en axel 22a, vilken är roterbart lagrad i rambalken 4.As previously mentioned, the guide wheels 14-16 are rotatably arranged in their respective frame portions 19, 23, 24. This frame portion has an upper part 21, which is fixed in the lower part 25 of a shaft 22a, which is rotatably mounted in the frame beam 4.

En bussning 26 eller liknande är fastsatt vid och omger axelns 22a undre del 25.A bushing 26 or the like is attached to and surrounds the lower portion 25 of the shaft 22a.

Därvid är ett diagonalliknande snitt 27 draget genom bussningen 26 och axelns 22a undre del, 10 15 505 604 3 så att styrhjulet 14 med axelns 22a undre del 25 kan vridas relativt axelns 22a övre del 2-8.Thereby, a diagonal-like section 27 is drawn through the bushing 26 and the lower part of the shaft 22a, so that the guide wheel 14 with the lower part 25 of the shaft 22a can be rotated relative to the upper part 2-8 of the shaft 22a.

Genom det sneda snittet 27 blir anslagsytorna vid snittet sneda, och detta innebär att avståndet A mellan den horisontella balken 4 och styrhjulets 14 kontaktyta med massabanan kommer att förändras vid vridning av styrhjulet. Denna ändring av avståndet A sker sålunda i detta fall på mekanisk väg. Naturligtvis skulle avståndet A i stället kunna ändras på hydraulisk eller pneumatisk väg.Due to the oblique section 27, the abutment surfaces at the section become oblique, and this means that the distance A between the horizontal beam 4 and the contact surface of the guide wheel 14 with the pulp web will change when the guide wheel is rotated. This change of the distance A thus takes place in this case by mechanical means. Of course, the distance A could instead be changed hydraulically or pneumatically.

Vill man sålunda få kontakthjulen 3 att lyfta frán massabanan vrids styrhjulen 14-16 på lärnpligt sätt medelst kolvcylindern 17, 18, varigenom avståndet A ökar. Vid fortsatt vridning av styrhjulen 14-16 kan sålunda massabanan enkelt förﬂyttas i sidled.If one thus wants the contact wheels 3 to be lifted from the pulp web, the guide wheels 14-16 are rotated in a learnable manner by means of the piston cylinder 17, 18, whereby the distance A increases. With continued rotation of the guide wheels 14-16, the pulp web can thus be easily moved laterally.

Naturligtvis är bussning/axelkonstruktionen 22a, 26 så anordnad vid snittet 27 att delama på ömse sidor om snittet hålls samman på lämpligt sätt.Of course, the bushing / shaft structure 22a, 26 is so arranged at the cut 27 that the parts on either side of the cut are held together in a suitable manner.

I texten har angivits materialbana. I detta uttryck innefattas inte bara massa- och pappersbanor utan även textil- och andra banor.The material path has been specified in the text. This expression includes not only pulp and paper webs but also textile and other webs.

Uppﬁnningen är naturligtvis ej begränsad till den visade och beskrivna utförings- formen utan kan modifieras inom rarnen för efterföljande patentkrav.The invention is of course not limited to the embodiment shown and described, but can be modified within the scope of the appended claims.
