Avsikten med uppfinningen är darfor att astadkomma en sadan anordning vid maskiner for framstallning av sadana foremal, att foremalen om sa onskas kunna utforas harda, dvs. vasentligt starkare komprimerade an tidigare. En sadan framstallningsmojlighet är av sarskild betydelse for eldfasta foremal framstallda av en fibermassa som innehaller as-best, och som exempel pa ett sadant foremal kan namnas smit trattar som sattas i ingjuten i sandformar for att hindra t. ex. smolt jam frau att riva solider omradet runt ingjutet under gjutningen. CLASS 80 a: 47 / INT. CLASS B 28 PATENT PERIOD FROM 14 DECEMBER 1960 GRANTED ON 15 NOVEMBER 1962 PUBLISHED ON 12 FEBRUARY 1963 Ans. 12 131/1960 on 14/12 1960Harlin a drawing DF EDNELL, ED Device for machine for forming pulp, specie & fibrous pulp Priority requested film on 5 January 1960 (Norway) Forms that are formed from pulp, especially fibrous pulp, fiber slurries or have received a large area of use in the form of egg cartons, flower pots that can be put into the soil together with the plant, and 1 form of other objects which, however, are relatively soft and have poor resistance to mechanical pans. The object of the invention is therefore to provide such a device in machines for producing such molds that the molds can be made hard if desired, i.e. significantly more strongly compressed than before. Such a production possibility is of particular importance for refractory molds made of a fibrous mass containing asbestos, and as an example of such a mold may be mentioned smith funnels which are put in cast in sand molds to prevent e.g. smolt jam frau to tear solids the area around the cast during casting.

Vid tidigare kanda maskiner har den mangd fibermassa som är nodvandig for framstallning av foremalen sugits fast vid en perforerad eller gallerliknande ytterform eller inner-form och i manga fall aro foremalen efter denna behandling fardiga att anvandas utan vidare formning eller bearbetning, men ytterligare bearbetning kan om sit fordras besta I att foremalen ytterligare tryckas samman mellan tva formar for att bortskaffa annu mer fuktighet, men vid denna sammanpressning kommer den formade fibermassan jute att ligga i ett slutet rum och den komprimering foremalen kunna utsattas for blir dorfor begransad. In prior art machines, the amount of fibrous mass required for the production of the foremale has been sucked onto a perforated or lattice-like outer or inner form and in many cases the foremals after this treatment are ready to be used without further shaping or processing, but further processing can The form is required to be further compressed between two molds to dispose of even more moisture, but during this compression the shaped fibrous mass of jute will be in a closed space and the compression the mold can be subjected to will therefore be limited.

Niir det galler fOremal som framstallas av eldfasta fibermassor kommer den sammantryckning som Or nodvandig for utdrivning air vatskan att vara betydligt storm an vad sum är fallet ndr det galler cellulosamassa och sammanpressningen eller komprimeringen av massan maste she i ett slutet rum, sit att inga delar av massan kunna forsvinna och vid foreliggande uppfinning Or den sit kallade innerformen i en maskin med tva formar sorn kunna forflyttas i forhallande till varandra forsedd med en forlangning som skjuter ut vid formens fria ande och som shall samverka med pafyllningsoppningen i den motsvarande ytterformen sit att oppningen stanges sit snart innerformen sattes i rorelse. In the case of grids formed from refractory fibrous masses, the compression required for expulsion of the air liquid will be considerably higher than in the case of cellulose pulp and the compression or compression of the mass must be in a closed space, so that no parts of the mass can disappear and in the present invention the so-called inner mold in a machine with two molds can be moved in relation to each other provided with a request which projects at the free spirit of the mold and which must cooperate with the filling opening in the corresponding outer mold so that the opening is closed its soon the inner form was set in motion.

Uppfinningen galler salunda en anordning vid en maskin for formning av massa, speciellt fibermassa, omfattande en pressanordRing bestaende av en ytterform och en inner-form som aro rarliga i forhallande till varandra, sit att massa som Jigger mellan dessa formar kan komprimeras och befrias fran fuktighet, och uppfinningen kannetecknas i det vasentliga av att innerformen am forsedd med en forlangning, som Or anordna.d att samverka med ytterformens ifyllningsoppning pa sadant soft, att forlangningen kommer att stanga oppningen under den forsta delen av innerformens rorelse. The invention thus applies to a device in a machine for forming pulp, in particular fibrous pulp, comprising a pressing device consisting of an outer mold and an inner mold which are movable in relation to each other, so that pulp which jiggers between these molds can be compressed and released from moisture. , and the invention can be characterized in the essential sense that the inner mold is provided with a extension, which is arranged to cooperate with the filling opening of the outer mold in such a soft manner that the extension will close the opening during the first part of the movement of the inner mold.

En foredragen utforingsforrn av uppfinningen kanneteeknas av att forlangningen innefattar en cylindrisk huvuddel och en konisk spets sum tillsammans bilda en forlangning air innerformen och i enlighet med annu ett kannetecken kan ifyllningsoppningen vara forsedd med ett axiellt forskjutbart foder eller ring vars storlek passar till forlangningen pa innerformen, och som vid sin axiella forskjutning kan stota ut foremalet sedan detta är fardigpressat. A preferred embodiment of the invention may be characterized in that the extension comprises a cylindrical body and a conical tip sum together to form an extension in the inner mold and in accordance with another feature, the filling opening may be provided with an axially displaceable liner or ring the size of the inner mold. and which in its axial displacement can eject the foremalt after it has been finished pressing.

Ett exempel pa uppfinningen är schematiskt yisat pa ritningen dar fig. 1 visar i starkt forenklad form ett snitt genom de viktigaste delarna av en maskin av det slag det hdr fraga om i lage for ifyllning air fibermassa, fig. 2 visar samma delar och detaljer som fig. 1 men med ytterform och innerform i lage for sammanpressning av den massa som fylldes i formrummet i fig. 1 och fig. 3 visar samma delar som de &riga figurerna, men i det lage som delarna ha sedan ett fardiggjort foremal ham stotts ut ur ytterformen. An example of the invention is schematically shown in the drawing, in which Fig. 1 shows in greatly simplified form a section through the most important parts of a machine of the type referred to here in the layer for filling air fiber pulp, Fig. 2 shows the same parts and details as Fig. 1 but with outer shape and inner shape in a layer for compressing the mass which was filled in the mold space in Fig. 1 and Fig. 3 shows the same parts as the other figures, but in the layer from which the parts have since a finished mold he has been ejected the outer shape.

Vid det utforande som visas pa ritningen omfattar anordningen en ytterform 1 och en nmerform 2 dar atminstone innerformen dr 2— — perforerad eller pa annat shit sa utford, att vatska kan tranga igenom, t. ex. som en form av tradnat eller liknande. Innerformen 2 kan films mot och fran ytterformen 1 med hjalp av t. ex. en hydraulisk drivanordning 3 med kolvstang 4. En styming 5 sorjer for att innerformen 2 Mlles i ratt stunning och innerformen 2 kan vara forsedd med kolvringar som tata mot styrningen 5, varvid det bildas en kammare 6 dar fibermassa som tillfOrs kammaren 6 genom oppningen 7 med hj alp av ett tillforselrOr 8 kan pressas ihop nar innerformen fOres mot ytterformen med hj alp av drivanordningen 3 till det lage som visas i fig 2. For att den onskade mangden massa skall kunna stangas in i kammaren 6 utan mojlighet att forsvinna nar sammantryckningen ager rum, är innerformen i enlighet med uppfinningen forsedd med en forlangning 9 som foretradesvis är cylindrisk och har en konisk spets 10. Den cylindriska delen av forlangningen passar precis i ifyllningsoppningen 7 och kommer darvid under den forsta fasen av innerformens 2 rorelse att stanga till oppningen 7 sit att fibermassan i formrummet 6 lute kan tranga ut och den blir da i ratt mangd komprimerad i vane enskilt fall till foremal med ensartade egenskaper. In the embodiment shown in the drawing, the device comprises an outer form 1 and a number form 2 in which at least the inner form is perforated or otherwise so challenged that liquid can penetrate, e.g. as a form of tradnat or the like. The inner mold 2 can be filmed against and from the outer mold 1 with the aid of e.g. a hydraulic drive device 3 with piston rod 4. A guide 5 ensures that the inner mold 2 is milled in a steering wheel and the inner mold 2 can be provided with piston rings which act against the guide 5, whereby a chamber 6 is formed where fiber mass is supplied to the chamber 6 through the opening 7 with by means of a supply pipe 8 can be compressed when the inner mold is moved towards the outer mold by means of the drive device 3 to the layer shown in Fig. 2. In order that the desired amount of mass can be forced into the chamber 6 without the possibility of disappearing when the compression takes place , the inner mold in accordance with the invention is provided with an extension 9 which is preferably cylindrical and has a conical tip 10. The cylindrical part of the extension fits exactly in the filling opening 7 and will thereby during the first phase of the movement of the inner mold 2 abut to the opening 7 sit that the fibrous mass in the mold space 6 lute can protrude and it is then compressed in the right amount in the usual case to form with even similar properties.

Om man sit onskar kan det i oppningen 7 monteras ett foder eller ring 11 som fir axiellt fOrskjutbar, och som har en invfindig diameter svarande mot ytterdiametern pa forlangningen 9. If desired, a liner or ring 11 can be mounted in the opening 7, which is axially displaceable, and which has an inner diameter corresponding to the outer diameter of the extension 9.

Sedan sammanpressningen av massan agt rum sasom antytts i fig. 2, dar t. ex. vatten strOmmar ut genom en ledning 12, skall det nu formade foremalet 13, t. ex. en tratt for det andamal som har namnts ovan, tagas ut och ytterformen 1 lyftes da samtidigt som innerformen 2 sanks tillbaka till utgangslaget. Ett stod 14 fOres darefter in under ytterformen 1 och automatiskt eller manuellt forskjutes sit ringen eller fodret 11, som darvid stoter ut det nu fardiga foremalet 13. De fardiga foremalen foras vidare till eventuell efterbehandling, som t. ex. putsning, om detta anses nOdvandigt. Since the compression of the pulp takes place as indicated in Fig. 2, where e.g. water flows out through a pipe 12, the now formed foremalt 13, e.g. a funnel for the second mold mentioned above is taken out and the outer mold 1 is then lifted at the same time as the inner mold 2 is lowered back to the starting layer. A stand 14 is then fed under the outer mold 1 and automatically or manually displaced by the ring or lining 11, which thereby ejects the now finished foremal 13. The finished foremals are passed on to any finishing, such as. plastering, if this is considered necessary.

Pet visade utforingsexemplet tj attar blott till att illustrera uppfinningen och satter ingen begransning for denna, i det det mycket val kan tankas andra utforingsformer an den som visats. T. ex. kan ytterformen 1 med for-del vara perforerad sit att vatska ocksa kan tranga igenom har, men bade detta och andra utforanden konama att falla inom ramen for uppfinningen om det mellan innerform och ytterform uppstar ett formutrymme som stangs av en utskjutande del sit snart innerformen sattes i rorelse. The exemplary embodiment shown only serves to illustrate the invention and does not place any limitation on it, in that much choice can be made of other embodiments than those shown. Eg. the outer mold 1 may advantageously be perforated so that liquid can also penetrate, but both this and other embodiments may fall within the scope of the invention if a mold space is formed between the inner mold and the outer mold which is closed by a projecting part as soon as the inner mold is set. in rorelse.
