Uppfinnare: L E Soderquist Prioritet begard fren den 28 mars 1961 (USA) Foreliggande uppfinning hanfOr sig till en anordning for uttagning av vulkade clack frau en dackpress. Uppfinningen Or av sarskilt var.- de vid avtagning av vulkade clack &An ett ldge kring en permanent narvarande mekanism, som bildar en stodblasa, och vid det avtagna dackets utmatning ur pressen. Inventor: L E Soderquist Priority Applied From March 28, 1961 (USA) The present invention relates to a device for removing vulcanized clack from a roofing press. The invention Or was of particular interest in the removal of vulcanized clack & An around a permanently present mechanism, which forms a bladder, and in the discharge of the removed tire from the press.

Vid tidigare konstruktioner har de mest verkningsfulla och praktiska avtagnings- och utmatningsmekanismerna for pressar med permanent narvarande blasa varit forsedda med ctt par eller tva armar, anordnade pa motsatta sidor om, I regel framfor och bakom formningsmekanismen. Pt pressunderlaget anordnade drivorgan forflyttar clarvid armarna for uppbarande av det vulkade clacket under avtagningsproceduren. For utmatning av det avtagna dacket har det darfar varit nodvandigt att sarskilt lyfta en av armarna i och for snedstallning av racket, som darvid kunde glida ut ur pressen under tyngdkraftens inverkan. In previous constructions, the most effective and practical removal and discharge mechanisms for presses with a permanently present bladder have been provided with a pair of pairs or two arms, arranged on opposite sides of, usually in front of and behind the forming mechanism. The drive means arranged on the press base clearly move the arms to support the vulcanized clack during the removal procedure. For discharging the removed deck, it has been necessary to lift one of the arms separately and for tilting the rack, which could thereby slide out of the press under the influence of gravity.

Olika mekanisraer har varit kanda for uppnhende av en lyftning av en arm Over den andra for erhallande av den onskade vinkeln eller snedstallningen lies ett avtaget dack. "lid hittills praktiskt arranda mekanismer, liar emellertid separata manover- eller drivlankar eller mekaniska element varit erforderliga for slutforande av den ena armens snedstallningsrorels e. Various mechanisms have been used to achieve a lifting of one arm over the other to obtain the desired angle or inclination of a decelerated deck. "hitherto practically arranged mechanisms, however, separate maneuvering or drive shafts or mechanical elements have been required for the completion of the one-arm tilting rudder e.

Enligt uppfinningen kannetecknas en dylik anordning darav, att utmatningsorganen in.- nefattar en stolpe, som Or fastgjord vid pressens underrede intill den nedre formhalvan och som uppbar en drivanordning for kringvridning av en i stolpens tvarriktning fad& pande och med en Linde i sidled ut Over stolpen utskjutande kort drivaxel, vid vars utskjutande ande Or fastgjord en arm, som svangbart uppbar en U-formad transportor, anordnad aft styras i sin rarelse genom en i sidled mat darifran utskjutande kamfoljares konstant bibehallna ingrepp med en mellan stolpen och transportoren anordnad stillastiende kam. The object of the invention is a device for removing vulcanized roofs from a press for forming and vulcanizing a deck, which press is provided with an upper and a lower mold half and a bladder, arranged to lift the vulcanized roof out of the lower mold half, which device comprises discharge means connected to the press, arranged to be controlled by cam means for moving to re-ring with the underside of a vulcanized clack and then to a sloping layer for tilting the deck in and for its discharge from the press. According to the invention, such a device can be characterized in that the discharge means comprise a post, which is attached to the base of the press next to the lower half of the mold and which has a drive device for rotating a fad in the transverse direction of the post and with a Linde laterally over the post. projecting short drive shaft, to which projecting spirit Or attached an arm, which pivotally supported a U-shaped conveyor, arranged aft is controlled in its rarity by a constantly maintained engagement of the cam follower projecting laterally therefrom with a stationary cam arranged between the post and the conveyor.

Enligt uppfinningen erhalles saledes en enhetlig anordning, som manovreras for lyftning av clacket och dess snedstallning i och for utmatning ur pressen. Denna dubbla manovrering mojliggores genom den styrningsrorelse for transportoren, som Ostadkommes genom kammen och kamfoljaren. According to the invention, a uniform device is thus obtained, which is maneuvered for lifting the clack and its inclination in and for discharging from the press. This double maneuvering is made possible by the steering movement of the conveyor which is achieved through the cam and the cam follower.

Utmatningsmekanismen enligt uppfinningen kan anordnas i ett lage, i vilket den p0 pressens franasida lamnar fritt ett utrymme, som erfordras eller med storre nytta anvIndes for anbringande av automatiska inmatningsmekanismer eller for betjaning ay forinhalvorna och formningsmekanismen.

Allman beskrivning. General description.

En dackpress, hos vi1ken foreliggande uppfinning kan tillampas, har isarforbara ovre och nedre formhalvor 20 och 21 och en i axiOlt centrerat lage anbragt formningsmekanism, som arbetar med en blasa. A roof press to which the present invention can be applied has ice-insertable upper and lower mold halves 20 and 21 and an axially centered layered forming mechanism which operates with a bladder.

Pressar av delta slag aro valkanda, och deras detaljer framgar exempelvis av amerikanska patentskriften 2 808 618. Dyllka pressar Oro sa konstruerade att maximal tillbakasvangning av den ovre formhalvan oak fritt utrymme Over den nedre formhalvan erhalles utan forlust av vardefullt utrymme ovanfor pressen. Detta slags pressar foredragas, men uppfinningen kan givetvis Oven tillampas hos pressar av andra slag och konstruktioner, exempelvis pressar, hos vilka den byre formhalvan icke f6res helt ur vagen och mot pressens ena sida, sa lange det vulkade dacket Or av- — —3 skulle emellertid aven kunna vara lagrat mellan uppat utskjutande partier pd. stolpen 36. Ytterandarna av aggregatets 40 axel uppbara langstrackta, bakatriktade, transport8- ren uppbarande och mantivrerande armar 41. Delta-type presses aro valkanda, and their details are shown, for example, in U.S. Pat. No. 2,808,618. This type of press is preferred, but the invention can of course also be applied to presses of other types and constructions, for example presses in which the bare mold half is not moved completely out of the carriage and towards one side of the press, as long as the vulcanized roof is however, can also be stored between upwardly projecting portions pd. post 36. The outer ends of the shaft 40 of the assembly 40 support elongate, rearward, conveyor-supporting and maneuvering arms 41.

Varje arm 41 uppbar vid sin bakre 'dude en i huvudsak U-formad transport& 42, som stracker sig framat och som ãr anordnad att gripa kring formningsmekanismen 30 och att uppbdra ett vulkat dick. I bakre hornet är vane transportOr 42 forsedd med en uppat- riktad kamfoljare 43. Kamfoljarens 43 bana bestammes genom de med speciell kontur for- sedda manovreringsytorna pa en stationar kam eller platta ,, som är fastgjord vid stolpens 36 sidor innanfOr transportorerna 42 och som stacker sig pa tvaren mot aggregatets 10 axel. Each arm 41 carried at its rear dude a substantially U-shaped transport & 42, which extends forward and which is arranged to grip around the forming mechanism 30 and to support a vulcanized dick. In the rear corner, the usual conveyor 42 is provided with an upright cam follower 43. The path of the cam follower 43 is determined by the specially contoured maneuvering surfaces on a stationary cam or plate, which is attached to the sides 36 of the post inside the conveyors 42 and as stacks. facing the axis of the unit 10.

Varje kamplatta 45 innefattar en halal och neat riktad krokt yta, som skar en framatriktad, nedatlutande linjar yta. Den krokta ytan är asymmetrisk, dvs. radien ãr variabel eller den innefattar ett flertal olika rather. Den krokta ytan borjar fOretradesvis vid det Owe bakre hornet av vane kam och stracker sig genom eller i en bage av atminstone 180°. Den linjara ytan skar den krokta ytan i ett avrundat hOrn och lutar nedat i erforderlig vinkel beroende pa pressens djup, formningsmekanismens 30 hojd efter utdragningen, det vulkade da.ckets tjocklek och andra hithOrande faktorer. En lutning nedat hos den linjdra ytan av 4-20° i forhallande till horisontalen Ar i regal tillfredsstallande hos anlaggningar enligt uppfinningen. Each cam plate 45 includes a halal and non-aligned curved surface which intersects a forward, downwardly sloping linear surface. The curved surface is asymmetrical, ie. the radius is variable or it includes a number of different ones. The curved surface preferably starts at the Owe rear corner of the vane comb and extends through or in a bag of at least 180 °. The linear surface cuts the curved surface into a rounded corner and slopes downwards at the required angle depending on the depth of the press, the height of the forming mechanism after extraction, the thickness of the vulcanized tire and other concaving factors. A downward slope of the linear surface of 4-20 ° in relation to the horizontal Ar in regal satisfactory in plants according to the invention.

I fig. 13 visas en fOredragen, latt framstallbar utforingsform av kamplattan 45, som exempelvis tillverkats av stalplat och dal- den krokta kamytan innefattar manovreringsytor med fyra olika radier. De fyra pa varandra foljande manovreringsytorna hos denna foredragna utforingsform av kamplattan 45 betecknus genom bokstaverna a, b, c, d och e. Den 'Angst bakat beldgna eller forsta manovreringsytan a styr transportOrernas 42 renelse framat fran tillhakadragningslaget (fig. 1). Denna rorelse borjar, da pressen är oppen och efter det att formningsmekanismens 30 vulstringar ha flyttats bort frail en formhalva; rorelsen bOr utforas hastigt. Foljaktligen är radien for ytan a den langsta (t. ex. omkring 34,3 cm), och dess mittpunkt ar foretradesvis belagen ovanfor axellinjen fOr aggregatets 40 axel, varigenom vid kamfOljarens 43 passage utmed ytan a en hastig r8relse framat av transportorerna 42 erhalles vid ett minimum av kolvrorelse hos en drivcylinder 38. Fig. 13 shows a preferred, easily manufacturable embodiment of the cam plate 45, which is for instance made of steel plate and the low curved cam surface comprises maneuvering surfaces with four different radii. The four consecutive maneuvering surfaces of this preferred embodiment of the battle plate 45 are designated by the letters a, b, c, d and e. The Anxiety baked bellows or first maneuvering surface a controls the purification of the conveyors 42 forward from the hook layer (Fig. 1). This movement begins when the press is open and after the beadings of the forming mechanism have been moved away from a mold half; the movement should be carried out quickly. Consequently, the radius of the surface is the longest (eg about 34.3 cm), and its center point is preferably located above the axis line of the axis of the assembly 40, whereby at the passage of the cam follower 43 along the surface a rapid movement forward of the conveyors 42 is obtained at a minimum of piston movement of a drive cylinder 38.

Den andra manovreringsytan b trader darefter i verksamhet foretradesvis utan avbrott efter foljarens 43 passage utmed ytan a, och transport8rerna befinna sig darefter i nastan horisontalt lage mellan det vulkade dacket och formhalvan, men icke i beroring med det vulkade dacket. Ytans b radie ãr kortare (t. ex. omkring 25,4 cm) an ytans a radie och dess mittpunkt ligger foretradesvis nedanfOr axellinj en fOr aggregatets 40 axel, sa att vid kamfoljarens 43 passage utmed ytan b en nagot framatriktad, men i stOrre grad uppatriktad rorelse av transportOrerna 12 erhalles. The second maneuvering surface b then subsequently enters into operation preferably without interruption after the passage of the follower 43 along the surface a, and the conveyors are then in a substantially horizontal position between the vulcanized deck and the mold half, but not in contact with the vulcanized deck. The radius b of the surface is shorter (eg about 25.4 cm) than the radius of the surface and its center point is preferably below the axis of the unit for the axis of the unit 40, so that at the passage of the cam follower 43 along the surface b a slightly forward, but to a greater extent upward movement of the carriers 12 is obtained.

Den tredje manovreringsytan c trader i verksamhet, fOretradesvis utan avbrott, efter kamfoljarens 43 passage utmed ytorna a och b, och vid slutet av denna rorelsefas befinna sig transportorerna 42 i ett i huvudsak horisontellt lage omedelbart nedanf Or det vulkade dacket (fig. 3). Ytans c radie är annu kortare (t. ex. omkring 20,3 cm) an radien for ytan b, och mittpunkten ligger foretradesvis nedanfor axellinj en fOr aggregatets 40 axel, sa att vid kamfoljarens 43 passage utmed ytan en i huvudsak uppatriktad rorelse av transportorerna 42 erhalles. The third maneuvering surface c enters into operation, preferably without interruption, after the passage of the cam follower 43 along the surfaces a and b, and at the end of this phase of movement the conveyors 42 are in a substantially horizontal position immediately below the vulcanized deck (Fig. 3). The radius of the surface c is even shorter (eg about 20.3 cm) than the radius of the surface b, and the center point is preferably below the axis line one of the axis of the unit 40, so that at the passage of the cam follower 43 along the surface a substantially upward movement of the conveyors 42 is obtained.

Den garde och sista krOkta manovreringsytan d styr transportorernas 12 rorelse uppat fran de dacket uppbarande lagena (fig. 2 eller 3) till borjan av snedstallningslaget (fig. 4). Ytans d radie ar betydligt langre (t. ex. omkring 30,5 cm) an. radien for ytan c, och mittpunkten ligger foretradesvis bakom axellinjen fOr aggregatets 40 axel och axellinjerna fOr ytorna b och c. The guarded and last curved maneuvering surface d controls the movement of the conveyors 12 upwards from the layers supporting the deck (fig. 2 or 3) to the beginning of the inclination layer (fig. 4). The radius of the surface is considerably longer (eg about 30.5 cm). the radius of the surface c, and the center point is preferably behind the axis line of the axis of the assembly 40 and the axis lines of the surfaces b and c.

Den linjara ytan pa en kamskiva 44 utgeres av partiet e. Overgangen mellan ytorna d och e an avrundad for underlattande av kamfoljarens 43 passage och for styrning av transport8rernas rorelse till andlaget f8r den framat- och uppatriktade rorelsen (fig. 5), varvid det vulkade dicket under tyngdkraftens inverkan inmatas fran pressen pa en bortforingstransportor 46. For erhallande av den onskade utmatningsvinkeln av joke mindre an 40° kan ytans e langd uppga till omkring 1,2 cm och lutningen nedat till 120. The linear surface of a cam disc 44 is formed by the portion e. The transition between the surfaces d and e is rounded to facilitate the passage of the cam follower 43 and to control the movement of the conveyors to the abutment of the forward and upward movement (Fig. 5), whereby the vulcanized the thickness under the action of gravity is fed from the press onto a removal conveyor 46. To obtain the desired discharge angle of the joke less than 40 °, the length of the surface can be up to about 1.2 cm and the slope down to 120.

For direkt samordning av transportorernas 42 rorelse med formningsblasans 38 utdragning ur ett vulkat clacks inre anvandes foretradesvis en elektrisk regleringsstromstallare 47, som till pressens huvudreglering signalerar att transportOrerna 42 befinna sig i lage for uppbarande av det vulkade dacket. Regleringsstromstallaren 47 kan manovreras genom ett anslag 48, som an fastgjordt vid svangtappen for det av havarmen och kedjehjulet bestaende aggregatet 37. For direct coordination of the movement of the conveyors 42 with the extension of the forming bladder 38 from the interior of a vulcanized clack, an electric control switch 47 is preferably used, which signals to the main control of the press that the conveyors 42 are in position to support the vulcanized tire. The control current switch 47 can be operated by a stop 48, which is attached to the pivot pin for the assembly 37 consisting of the lever arm and the sprocket.

Nan transportorarmarna 42 befinna sig i laget enligt fig. 3 och 6 och stromstallaren 47 har man8vrerats, kan blasan 3,3 utdragas. When the conveyor arms 42 are in the team according to Figs. 3 and 6 and the current generator 47 has been operated, the bladder 3,3 can be pulled out.

Blâsans utdragning kan astadkommas genom isarforing av ringarna 31 och 32, vilka efter pressens oppnande och fore transportorarmamas 42 rorelse framat ha tillsammans lyfts till ett age, i vilket det vulkade dacket befinner sig ovanfor och ur beroring med for-men (fig. 2). Blasans utdragning är narmare beskriven i amerikanska patentskriften 4— — 2 495 663, framfor alit med hanvisning till fig. 7 och 8. Bland de fordelar som uppnas med detta satt att utdraga blasan, kan omnamnas att vulsterna pa sjalva det vulkade dacket tjanstgara for direkt hopfallning av blasan 33 i fyra eller flera veck med liten diameter, varigenom skavande eller notande beraring med blasans ytterytor undvikes eller reduceras vid pafking av ett ovulkat dack eller utmatning av ett vulkat däck, vilket medlar star-re livslangd hos blOsan. Dackvulsterna frigoras aven likformigt fran ringarna 31 och 32 och vid avtagning behover det frigjorda dacket rara sig uppat utmed mindre an halften av blasans 33 hojd, varigenom bade dacket och blasan skyddas. The extraction of the bladder can be effected by ice-feeding the rings 31 and 32, which after opening the press and the movement of the front conveyor arms 42 have been lifted together to an age in which the vulcanized roof is above and out of contact with the mold (Fig. 2). The extraction of the bladder is described in more detail in U.S. Pat. Nos. 4 - 2,495,663, above all with reference to Figs. 7 and 8. Among the advantages obtained with this method of extracting the bladder, it may be mentioned that the beads on the vulcanized roof itself serve directly. collapse of the blister 33 into four or more small diameter folds, thereby avoiding or reducing abrasion with the outer surfaces of the blister when puffing an unvulcanized tire or discharging a vulcanized tire, which mediates longer life of the blister. The roof beads are also released uniformly from the rings 31 and 32 and upon removal the released roof needs to move upwards along less than half of the height of the bladder 33, whereby both the roof and the bladder are protected.

' Mekanismens 35 manovrering Sr emellertid forenlig Sven med andra satt for utdragning av blasan, exempelvis den i amerikanska patentskriften 2 495 664 beskrivna tekniken, vid vilkeri blasans 33 utdragning framst astadkommes genom en. uppatriktad rorelse av den. ovre ringen 31, medan transportararmar 42 tjana att sa smaningom lyfta det vulkade clacket under tiden far blasans bortforande till det slutliga lyftningslaget (fig. 5). Vid anvandning av den ena eller andra metoden far den langstrackta formningsmekanismen i sin helhet sjunka tillbaka mot den nedre formhalvan 21 for underlattande av det vulkade dackets slutliga utmatning och inf8rande av ett ovulkat dack. However, the maneuvering of the mechanism 35 is compatible with other methods of pulling out the bladder, such as the technique described in U.S. Pat. No. 2,495,664, in which pulling out of the bladder 33 is accomplished by a. upward movement of it. the upper ring 31, while conveyor arms 42 serve to gradually lift the vulcanized clack meanwhile the blister is removed to the final lifting layer (Fig. 5). When using one or the other method, the elongate forming mechanism as a whole is allowed to sink back towards the lower mold half 21 to facilitate the final discharge of the vulcanized tire and the insertion of an unvulcanized tire.

Ph omse sidor om tvfirstycket 83 aro lampliga transportorrullar 84 anordnade, vilka stracka sig over transportorens hela bredd. Each conveyor 42 comprises a substantially U-shaped frame with forwardly directed or projecting arm portions, arranged to grip around the forming mechanism 30. Each arm portion is formed in four rows by a pair of frame plates. Pet inner pair of frame plates 81 Or farce - - with suitable bores for receiving the shaft journal 80 on the corresponding conveyor arm. The outer pair of frame plates & 2 are fastened together in a uniform structural element with the frame plates 81 by means of a crosspiece 83. On opposite sides of the two-piece piece 83, suitable conveyor rollers 84 are arranged, which extend over the entire width of the conveyor.

Varje utskjutande armparti pa en transport& 42 uppbar dackingreppsorgan 85, vilka uppbara och lyfta ett vulkat clack. Varje par ramplattor 81 och 82 är kopplat genom ett par tvfirstanger 86 med liten diameter. Sasom tydligast framgar av fig. 7, uppbfira tvarstingerna 86 en vingformad hallare 87, som i narheten av vartdera hornet uppbar foretradesvis koniska rullar 88 for ingrepp med undersidan av ett vulkat thick. Varje hallare 87 är fastgjord vid ett par stanger 86 med hjfilp av en spannplatta 89 och en spfinnbult 90. Hallarens 87 arbetslfige är installbart fOr installning av mekanismen 35 for utmatning av clack med olika dimensioner. Each projecting arm portion on a conveyor & 42 carries roof engaging means 85, which support and lift a vulcanized heel. Each pair of frame plates 81 and 82 is connected by a pair of small diameter two rods 86. As most clearly shown in Fig. 7, the transverse strings 86 provide a wing-shaped holder 87, which in the vicinity of each horn preferably carries conical rollers 88 for engagement with the underside of a vulcanized thick. Each holder 87 is fixed to a pair of rods 86 by means of a clamping plate 89 and a spinneret 90. The working member of the holder 87 is installable for installing the clack discharge mechanism 35.
