Transport& ren enligt uppfinningen innebar ett framsteg vid dacktillverkningen, genom att ovulkade dacksband, som ha uppbyggts pa nagot annat stalle oak transporterats fram av transport& rer, gaffeltruckar eller liknande, overforas effektivt Iran tillforseldonet, hanteras utan deformering och hallas i lampligt lage for att latt gripas av pressens beskiekningsmekanismer. Inventor: L E Soderquist Priority Required from May 19, 1959 (USA) The present invention aims to improve presses intended for automatic forming and vulcanization of tires. The conveyor according to the invention was an advance in the manufacture of roofs, in that unvulcanized dacks, which have been built up elsewhere or transported by conveyors, forklifts or the like, are efficiently transferred to the Iran supply, handled without deformation and kept in a suitable position for easy gripping. of the press mechanisms of the press.

Foreliggande uppfinning hanfor sig till en vulkpress, for formning och vulkning av ovulkade dacksband, vilken omfattar skiljbara formdelar och en beskickningsmekanism mellan motstaende, fasta, vertikala ramdelar anordnad att mottaga ett ovulkat dacksband fran en transport& och att installa bandet mitt for den nedre formdelen. Transportoren är harvid anordnad mellan tva utliggare, som stracka sig utat fran de vertikala ramdelarna. 'Fransportoren omfattar en vagn, som uppbares av utliggarna, ett barorgan, som uppbares av vagnen och är anordnat att uppbara det ovulkade dacksbandet, samt drivorgan anordnade att fora vagnen Over utliggarnas yttre ande och mellan utliggarna till beskickningsmekanismen, sâ att dackbanden kunna Overlamnas till densamma. The present invention relates to a vulcanizing press for forming and vulcanizing unvulcanized dacksband, which comprises separable mold parts and a loading mechanism between opposite, fixed, vertical frame parts arranged to receive an unvulcanized dacksband from a transport & to install the belt in the middle of the lower mold part. The conveyor is then arranged between two outriggers, which extend outwards from the vertical frame parts. The fringe conveyor comprises a trolley supported by the outriggers, a bar member supported by the trolley and arranged to support the unvulcanized dacksband, and drive means arranged to feed the trolley over the outer spirit of the outriggers and between the outriggers of the loading mechanism so that the roof straps can be left to it. .

Genom uppfinningen astadkommes en forbattrad drift av pressen, sa att ett ovulkat dacksband kan overforas Iran tillforseldonet, hanteras utan ytterligare deformation och latt gripas av en beskickningsmekanism for en automatiskt beskickad press. The invention provides an improved operation of the press, so that an unvulcanized frequency band can be transferred to the Iran supply device, handled without further deformation and easily gripped by a loading mechanism for an automatically loaded press.

De pressar, vid vilka uppfinningen tillampas, ha sasom bast visas i fig. 1, 4, 7 och 8 i och for sig kanda konstrUktion och arbetssatt exempelvis enligt amerikanska patentskriften 2 927 343 och kunna vara utforda sa, att det Or majligt att svanga tillbaka den ovre formhalvan 20 maximalt och f0 st6rsta majliga utrymme ovanfor den nedre formhalvan 21. Denna typ av pressar f8redras, ehuru det är 2— — uppenbart, att pressar av andra typer och av annan konstruktion kunna anya.ndas vid tilllampning av uppfinningen, om endast ett ovulkat dacksband kan installas mitt for en nedre formhalva 21, da pressen ar oppen. The presses to which the invention is applied have as shown in Figs. 1, 4, 7 and 8 per se known construction and operation, for example according to U.S. Pat. No. 2,927,343, and may be so challenging that it may be necessary to swing back the upper mold half 20 maximum and largest male space above the lower mold half 21. This type of press is preferred, although it is obvious that presses of other types and of other construction can be used when applying the invention, if only an unvulcanized dacksband can be installed in the middle of a lower mold half 21, when the press is open.

Pressarna kunna sasom visas anvandas med eller utan en. uppblasbar vulkslang, d. v. s. mekanismen for formning av dacket kan vara av typen mer permanent vulkslang eller membran eller kan vara av typen for vulkning utan vulkslang. The presses can, as shown, be used with or without one. inflatable volcanic hose, i.e. the mechanism for forming the tire may be of the more permanent volcanic hose or diaphragm type or may be of the volcanic hose type without vulcanized hose.

Sasom visas pa ritningarna uppbares de undre eller fasta formhalvorna 21 av ett underrede 22. De rorliga, ovre formhalvorna uppbaras fran ett tvarstycke 23. Pa motsatta sidor av de nedre formhalvorna 21 finnas styrplatar 24, som stracka sig uppat Iran underredet 22. Varje styrpla't 24 har tva parallella, framre och bakre styrspar 25 och 26. Vid vardera anden av tvarstycket finnas styrarmar med framre och bakre rullar 27 och 28, vilka kunna ingripa i motsvarande styrspar 25 och 26. Tvarstycket 23 är ledbart f8rbundet med ovre anden av tva drivande lankar 30 pa motsatta sidor av pressen och utanfor styrplatarna 24. Lankarna 30 drivas av stora, motordrivna hjul 31 for lyftning av tvarstycket. Under oppningsrorelsen farskjutas rullarna 27 och 28 forst till ovre anden av sina styrspar 25 och 26. De framre rullarna rora sig sedan langs en bakat och nedat lutande yta 32 pa styrplatarna 24, medan de bakre rullarna 28 rora sig nedat i de bakre styrsparen 26, tills tvarstycket 23 befinner sig ovanfOr styrplatarnas 24 Overkant. As shown in the drawings, the lower or fixed mold halves 21 are supported by a chassis 22. The movable upper mold halves are supported from a crosspiece 23. On opposite sides of the lower mold halves 21 are guide plates 24 extending upwardly into the Iran chassis 22. Each guide plate. t 24 has two parallel, front and rear guide pairs 25 and 26. At each end of the crosspiece there are guide arms with front and rear rollers 27 and 28, which can engage in corresponding guide pairs 25 and 26. The crosspiece 23 is articulated connected to the upper spirit of two driving links 30 on opposite sides of the press and outside the guide plates 24. The links 30 are driven by large, motor-driven wheels 31 for lifting the crosspiece. During the opening movement, the rollers 27 and 28 are first moved to the upper spirit by their guide pairs 25 and 26. The front rollers then move along a rearwardly inclined and downwardly inclined surface 32 of the guide plates 24, while the rear rollers 28 move downwards in the rear guide pairs 26. until the crosspiece 23 is above the upper edge of the guide plates 24.

Beskickningsmekanismerna for ovulkade band, vilka generellt betecknas med 35, uppbaras av och aro lampligen anordnade radiellt i forhallande till en axel 36, som stracker sig tvars Over pressen ovanfor den nedre formhalvan 21. Axeln 36 är lagrad roterbart vid andarna. Vid pressens ena, framre horn roterar axeln 36 i ett hus 37 vid ovre anden av en vertikal I-balk 38 fast pa insidan av den ena styrplaten 24. Huset 37 innehaller mekanismen for drivning av axeln 36, sa. att beskickningsmekanismerna 35 foras mot och fran de undre formhalvorna 21. Sasom visas kan drivmekanismen utgoras av en cylinder 39, som är fast ledbart i styrplaten 24 och har en utskjutbar kolv forbunden med en vevarm 40 fastkilad pa axeln 36. Nagon annan lamplig mekanism for vridning av axeln 36 kan anvandas, om sa Onskas. The loading mechanisms for unvulcanized belts, generally designated 35, are supported by and are suitably arranged radially in relation to a shaft 36 extending transversely across the press above the lower mold half 21. The shaft 36 is rotatably mounted by the spirits. At one front horn of the press, the shaft 36 rotates in a housing 37 at the upper end of a vertical I-beam 38 fixed on the inside of one guide plate 24. The housing 37 contains the mechanism for driving the shaft 36, so. that the loading mechanisms 35 are guided towards and from the lower mold halves 21. As shown, the drive mechanism can be constituted by a cylinder 39, which is fixedly articulated in the guide plate 24 and has an extendable piston connected to a crank arm 40 wedged on the shaft 36. Any other suitable mechanism for rotation of the shaft 36 can be used, if said Onskas.

Varje beskickningsmekanism- 35 omfattar ocksa tva armar 41, som aro fasta i axeln 36 och uppbara ett block 42. Varje block 42 bildar den. centrala eller axiella delen av en chuck, som lampligen har flera bagformiga segment 43, vilka aro anpassade efter inner-diameter n till det ovulkade dacksbandets vulstdelar. Icke visade medel forbundna med blocket 42 och segmenten 43 aro anordnade fOr expandering av chucken, sa att segmenten verka mot insidan av det ovulkade dacksbandet. Each loading mechanism also includes two arms 41 which are fixed to the shaft 36 and support a block 42. Each block 42 forms it. central or axial part of a chuck, which suitably has several bag-shaped segments 43, which are adapted to the inner diameter n of the bead parts of the unvulcanized dacksband. Not shown means connected to the block 42 and the segments 43 are arranged to expand the chuck, so that the segments act against the inside of the unvulcanized dacks band.

Tillh8rande transportor, som sarskilt är avsedd for frammatning av ovulkade dacksband for personbilsdack betecknas generellt med 45 I fig. 1-6. Transportorens 45 ram stracker sig till pressens framsida och uppbares lampligen av de vertikala styrplatarna 24. Associated conveyor, which is especially intended for feeding unvulcanized dacks tires for passenger car tires, is generally denoted by 45 In Figs. 1-6. The frame of the conveyor 45 extends to the front of the press and is suitably supported by the vertical guide plates 24.

Sett i fig. 4 omfattar transportorramens byre hagra sida en rektangular ramdel 46, som an fast pa utsidan av beskickningsmekanismens has 37. Transportorramens nedre hogra sida har en nagot trapetsformig ramplatta 47 fast pa insidan av styrplaten 24 i ett plan, som befinner sig pa ungefar samma horisontella niva som tvarstycket 23, da pressen är sluten. Transportorramens byre vanstra sida omfattar en. rektangular ramdel 48, fast i en platta 50, som liar dubbel uppgift och uppbares vid ovre anden av en vertikal I-balk 38' fast pa insidan av den vanstra styrplaten 24'. Plattan 50 uppbar lampligen bade ramdelen 48 och den vanstra anden av beskickningsmekanismens axel 36. Transportorramens nedre vanstra sida omfattar en platta 49, som liknar plat-tan 47 och aven är fast pa insidan av styrplaten 24'. As seen in Fig. 4, the right side of the conveyor frame comprises a rectangular frame portion 46 which is fixed to the outside of the hatch of the loading mechanism 37. The lower right side of the conveyor frame has a slightly trapezoidal frame plate 47 fixed to the inside of the guide plate 24 in a plane the same horizontal level as the crosspiece 23, when the press is closed. The left side of the conveyor frame includes one. rectangular frame part 48, fixed in a plate 50, which has a double function and is supported at the upper end by a vertical I-beam 38 'fixed on the inside of the left guide plate 24'. The plate 50 suitably supported both the frame part 48 and the left end of the shaft 36 of the loading mechanism. The lower left side of the conveyor frame comprises a plate 49, which is similar to the plate 47 and is also fixed on the inside of the guide plate 24 '.

Transportorens 45 ram omfattar vidare ett utliggarorgan pa den hogra och den vanstra sidam, De bagge utliggarorganen stracka sig fribarande utat fran pressen och begransa och styra i samverkan det bandet overforande elementets 60 rorelse, sasom kommer att beskrivas narmare i det foljande. I pressen enligt fig. 1-6 aro bagge utliggarorganen identiskt lika churn spegelvanda. The frame of the conveyor 45 further comprises a cantilever member on the right and left sides. The rear cantilever means extend freely from the press and in cooperation define and control the movement of the belt transferring the element 60, which will be described in more detail below. In the press according to Figs. 1-6, the ram outriggers are identical to churn mirror water.

Sasom bast visas i fig. 1-3 omfattar det hogre utliggarorganet tva samverkande U-bal- Utliggarorganet omfattar salunda en yLtre skena 52 och en inre skena 53. Vardera skenan ar i ovre anden fast i ramdelen. 46. I nedre an-den Sr vardera skenan fast i ramplattan 47. Skenorna ha i stort sett V-form med den inre skenan 53 passande tan mot den yttre skenan 52 utom vid spetsen, dar skenorna ga ifran varandra for ett andamal, som skall beskrivas narmare I det foljande. Intill spetsen pa. vardera skenan anordnas lampligen stravor. Dessa kunna ha formen av en vertikal vinkelbalk 54 och en korsande vinkelbalk 55. Vanstra sidans utliggarorgan är lampligen utfort ph exakt samma satt och de bagge utliggarorganen aro forbundna med varandra genom en tvarbalk 56. As shown in Figs. 1-3, the right beam member comprises two cooperating U-beam members. The beam member thus comprises an outer rail 52 and an inner rail 53. Each rail is fixed in the upper part in the frame part. 46. In the lower end, each rail is fixed to the frame plate 47. The rails have a generally V-shape with the inner rail 53 fitting tan against the outer rail 52 except at the tip, where the rails gave apart for a second purpose, which is to described in more detail in the following. Next to the tip pa. each rail is suitably arranged penalties. These may be in the form of a vertical angle beam 54 and an intersecting angle beam 55. The outrigger members of the left side are suitably designed in exactly the same way and the ram outriggers are connected to each other by a crossbeam 56.

De bagge skenorna 52 och 53 bilda en sluten bana eller styrning for en travers eller vagn for det bandet transporterande elementet eller bygeln 60. Sasom framgar av fig. 4-6 har vagnen vid vardera sidan en kort, rektangular ramdel 61 med axeltappar 62, som stracka sig in i skenorna 52 och 53. Foljaraxeln 62 uppbar en rune 63 med en diameter, som ár noga avpassad efter skenans 52 hire bredd. Ledaraxeln 64 uppbar ett liknande hjul eller — —3 rulle 65 i anpassning efter skenan 53. Foljaraxeln 62 slutar vid ramdelen 61 och Or fast medelst ett fastorgan 66. Ledaraxeln 64 strac- ker sig genom det rektangulara organet 61 for att bilda ett faste for en lampligen fast bar- stang 67, som stracker sig mellan vagnens vanstra och hogra sida. Den ovre anden av tva fastflansar 68, en for varje bygel 60 är fast i den transversella stangen 67. Den ovre anden av varje par fastflansar slutar i en speciellt utformad hallare 69 for uppbarande air ett ovulkat dacksband. Lampliga medel 69a kunna vara anordnade for reglering av byglarnas 60 hajd i anpassning efter ovulkade band med olika vulstdiameter. The ram rails 52 and 53 form a closed path or guide for a traverse or carriage for the belt transporting element or bracket 60. As shown in Figs. 4-6, the carriage has on each side a short, rectangular frame part 61 with axle pins 62, which extend into the rails 52 and 53. The follower shaft 62 carried a rune 63 with a diameter which is carefully adapted to the width of the rail 52. The guide shaft 64 carried a similar wheel or roller 65 in adaptation to the rail 53. The follower shaft 62 terminates at the frame portion 61 and is fixed by means of a fixed member 66. The guide shaft 64 extends through the rectangular member 61 to form a fixed member. suitably fixed bar rod 67, which extends between the left and right sides of the carriage. The upper spirit of two fixed flanges 68, one for each bracket 60, is fixed in the transverse rod 67. The upper spirit of each pair of fixed flanges terminates in a specially designed holder 69 for supporting air an unvulcanized dacks band. Lamp means 69a may be provided for adjusting the height of the stirrups 60 in adaptation to unvulcanized bands of different bead diameters.

Sasom framgar av fig. 6 uppbar varje axel 64 mellan den rektangulara ramdelen 61 och den inre skenan 53 en ledbart anordnad lank 70. Denna forbinder andarna pa en andlos kedja 72, som driver vagnens rOrelse. As can be seen from Fig. 6, each shaft 64 between the rectangular frame member 61 and the inner rail 53 carried a hinged link 70. This connects the spirits of a breathless chain 72 which drives the movement of the carriage.

Sasom franagar av fig. 1-3 fir varje kedja 72 lagd runt en serie pa tre brytrullar. En stor, icke driven brytrulle 73 är anordnad intill utliggarnas spats och uppbaras lampligen av den vertikala stravan 54. En andra eller inre brytrulle 74 dr anordnad vid den rorliga an-den av en kedjehjulsarm 75, som Or fast svangbart vid 76 i nedre, inre hornet air vardera plattan 47 och 49. Vardera kedjan drives av ett drivande kedjehjul 77 yid anden av en axel 78, som stracker sig mellan utliggarna och Or lagrad i ramdelarna 46 och 48. Axeln 78 an genom en lamplig transmission forbunden med den utgaende axeln till en kuggvaxelmotor 79 med lagt utgaende varvtal. As shown in Figures 1-3, each chain 72 is laid around a series of three breaker rollers. A large, non-driven breaker roller 73 is arranged adjacent to the tip of the outriggers and is suitably supported by the vertical strut 54. A second or inner breaker roller 74 is provided at the movable end of a sprocket arm 75 which is pivotally pivotable at 76 in the lower inner hornet air each plate 47 and 49. Each chain is driven by a driving sprocket 77 yid spirit of a shaft 78 extending between the outriggers and Or mounted in the frame members 46 and 48. The shaft 78 is connected by a lamp transmission to the output shaft to a gear motor 79 with added output speed.

Transportoren 45 verkar pa foljande satt. Ett ovulkat dacksband B Overfares fran en icke visad tillforselanordning och plaeeras i transportbygeln 60 i dess nedersta lage, som visas i fig. 1. Motorn 79 startar sedan for att driva kedjorna 72 medurs sett i fig. 1. Vagnen med rullarna 63 och 65 ingripande i var sin av skenorna 52 och 53 ror sig mot utliggarnas spets. Under denna rorelse ga axeltapparna 62 och rullarna 63 fore axeltapparna 64 och rullarna 65. Vid spetsen divergera emellertid skenorna 52 och 53 sasom har beskrivits ovan. Vid stallet med den storsta divergensen ar avstandet mellan skenorna 52 och 53 lika med avstandet mellan axlarna 62 och 64, som aro fasta i den korta, rektangulara ramdelen 61. Harigenom blir det mojligt for axlarna 64 att sakta rora sig framfor axlarna 62 vid utliggarnas yttre dude och halla vagnens ramdelar 61 i samma inbardes lagen som vid barjan av transporten under den slutliga rorelsen mot beskickningsmekanismerna 35. Den rorliga monteringen av det nedre, icke drivna kedjehjulet 74 kompenserar for minskningen av kedjornas 72 effektiva langd under denna del av rorelsen. Detta tillstand visas i fig. 2. Conveyor 45 operates in the following manner. An unvulcanized frequency band B is passed over from a supply device (not shown) and placed in the transport bracket 60 in its lower layer, as shown in Fig. 1. The engine 79 then starts to drive the chains 72 clockwise as shown in Fig. 1. The trolley with the rollers 63 and 65 engages each of the rails 52 and 53 moves towards the tip of the outriggers. During this movement, the shaft journals 62 and the rollers 63 move in front of the shaft journals 64 and the rollers 65. At the tip, however, the rails 52 and 53 diverge as described above. In the case of the largest divergence, the distance between the rails 52 and 53 is equal to the distance between the shafts 62 and 64, which are fixed in the short, rectangular frame part 61. This makes it possible for the shafts 64 to move slowly in front of the shafts 62 at the outer dude and keep the frame parts 61 of the carriage in the same manner as at the beginning of the transport during the final movement towards the loading mechanisms 35. The movable mounting of the lower, non-driven sprocket 74 compensates for the reduction of the effective length of the chains 72 during this part of the movement. This condition is shown in Fig. 2.

Lampliga, icke visade stromstallare kunna anordnas for att stoppa motorn 79, om icke beskickningsmekanismerna 35 befinna sig i de t i fig, 2 visade laget, d. v. s. i lampligt lage fOr att taga emot banden B i byglarna 60. Dh be- skickningsmekanismerna befinna sig i lamp- ligt lage, r8r sig vagnen framat i sitt forutbestamda lage fran utliggarorganens yttre ande, tills de ovulkade banden B befinna sig mitt for eller i overforingslaget till beskickningsmekanismerna 35. Shsom visas med brutna linjen i fig. 2 ligger det ovulkade bandets )3 axel i samma vertikalplan som och parallellt med beskickningsmekanismens 35 axel ehuru nagot lagre, sa att segmenten 43 vid expansionen gripa eller lyfta bandet B fran bygeln 60. detta lage kunna finnas ytterligare, lampliga stromstallare fOr expandering ay segmenten 43, omkastning av motorn 79 och for beskickningsmekanismernas rorelser. Lampable stables, not shown, can be arranged to stop the motor 79, unless the loading mechanisms 35 are in the layer shown in Fig. 2, i.e. in a lampable position to receive the belts B in the jumpers 60. That is, the loading mechanisms are in the lamp low, the carriage moves forward in its predetermined position from the outer spirit of the outriggers, until the unvulcanized bands B are located in front of or in the transfer layer to the loading mechanisms 35. As shown by the broken line in Fig. 2, the axis of the unvulcanized band 3 lies in the same vertical plane as and parallel to the axis of the loading mechanism 35, although slightly lower, so that during expansion the segments 43 grasp or lift the belt B from the shackle 60. this layer may have additional, suitable current for expansion of the segments 43, reversing of the motor 79 and for the movements of the loading mechanisms. .

Om sa 8nskas kan man amen anbringa andra lampliga stromstallare for att halla traversvag- nen och en bygel 60 i onskat mellanlage avail- for golvet, lampligen intill utliggarorganens ytterandar. I praktiken komma salunda tva ovulkade band B, av vilka det ena befinner sig ph beskickningsmekanismen 35 och det andra i bygeln 60, att vara direkt tillgangliga for beskickning av den nedre formhalvan 21 med intervall, som bestammas av vulktiden for (lacket. Delta Or sarskilt fordelaktigt, dd. en. serie av flera pressar, som skola halla olika vulkningstider, skola overvakas av en enda man. If desired, other suitable stables can be fitted to hold the trolley and a bracket 60 in the desired intermediate position available for the floor, suitably next to the outer ends of the outriggers. Thus, in practice, two unvulcanized belts B, one of which is located in the loading mechanism 35 and the other in the shackle 60, will be directly accessible for loading the lower mold half 21 at intervals determined by the vulcanizing time of the paint. advantageously, dd. a series of several presses, which shall hold different vulcanization times, shall be supervised by a single man.

Fig. 3 visar tillstandet, de. byglarna 60 ha atervant till sitt lagsta lage och ha tagit emot namnda band B', medan beskickningsmekanismerna 35 ha fort foregaende band B till de nedre formhalvorna 21. Fig. 3 shows the state, de. the stirrups 60 have atervant to their lowest layer and have received the said band B ', while the loading mechanisms 35 have fast preceding band B to the lower mold halves 21.

En transport& sarskilt avsedd for beskickning av stora och tunga, ovulkade dacksband sasom lastbilsdack betecknas med 90 i fig. 712. Transportorens 90 ram stacker sig frau pressens framsida och uppbares lampligen av platarna 24. A conveyor & especially intended for loading large and heavy, unvulcanized dacksband such as truck tires is denoted by 90 in Fig. 712. The frame of the conveyor 90 extends from the front of the press and is suitably supported by the plates 24.

Transportorens 90 ram omfattar ett utliggarorgan till hoger och ett till vanster. De bagge utliggarorganen stracka sig fribarande utat frail pressen och styra tillsammans sjalva bandhallarens 110 rorelse sasom kommer att beskrivas narmare i det faljande. I pressen enligt fig. 7-12 Oro de bagge utliggarorganen exakt lika med undantag for att de Oro spegelvanda. The frame of the conveyor 90 comprises a cantilever member to the right and one to the left. The rammed outrigger members extend freely to the frail press and together control the movement of the belt holder 110 itself, which will be described in more detail below. In the press according to Figs. 7-12, the ridge outriggers are exactly the same except that they are mirrored.

De bagge utliggarorganen bildas av tva sidobalkar 91, som Oro forbundna med varandra vid innerandarna genom en tvarbalk 92a. Balkarna 91 och 92 Oro lampligen hopsvetsade och uppbaras av konsoler 93 vid 8vre anden av vertikala 1-balkar 38, sa. att de icke hindra beskickningsmekanismernas 35 arbete. Balkarna 91 Oro lampligen forstarkta i ytterandarna och stagas av lampliga stravor 94, som stracka sig uppat fran styrplatarna 24. Utliggarorganen kunna forstarkas ytterligare genom andra tvarbalkar sasom visas vid 92b. The ram outriggers are formed by two side beams 91, which are connected to each other at the inner ends by a cross beam 92a. The beams 91 and 92 are suitably welded together and supported by brackets 93 at the 8th spirit of vertical 1-beams 38, said. that they do not hinder the work of the mission mechanisms. The beams 91 are suitably reinforced in the outer ends and are braced by lamplike punches 94, which extend upwards from the guide plates 24. The outrigger means can be further reinforced by other crossbeams as shown at 92b.

Sasom bast visas i fig. 9-12 har varje sidobalk 91 pa insidan am ytteranden en kort axel 4-- — 95. Denna uppbares lampligen av ett install-hart block 96, som ãr ledbart fast i balken 91, och pa densamma aro lagrade ett kedjehjul 97 och en linskiva 98 och hallos kvar medelst ett stopporgan 99. As shown in Figs. 9-12, each side beam 91 on the inside of the outer end has a short axis 4-- - 95. This is suitably supported by an installed hard block 96, which is articulated in the beam 91, and mounted thereon. a sprocket 97 and a pulley 98 and retained by a stop means 99.

Mellan sidobalkarnas 91 inre andar stracker sig en lang, tvargaende axel 100, som ar lagrad roterbart i lampliga lager. Intill sidobalkarna uppbar axeln 100 vid vardera anden ett fast kedjehjul 101 och en linskiva 102. Axelns 100 hogra ande är genom en lamplig transmission forbunden med den utgaende axeln till en kuggvaxelmotor 104 med lagt utgaende varytal. Varje bakre kedjehjul 101 ar forbundet med ett framre kedjehjul 97 genom en andlos kedja 105. Between the inner spirits of the side beams 91 extends a long, transverse shaft 100, which is rotatably mounted in lamp bearings. Adjacent the side beams, the shaft 100 carries at each end a fixed sprocket 101 and a pulley 102. The shaft of the shaft 100 is connected by a lamp transmission to the output shaft of a gear shaft motor 104 with a set output speed. Each rear sprocket 101 is connected to a front sprocket 97 by a spiritless chain 105.

Bandhallarna eller byglarna 110 lyftas till utliggarorganens ytterandar medelst linor 111 fasta i lintrummorna 102 och dragna over de framre brytskivorna 98. Varje lina 111 ãr forbunden med sidan av en vagn for byglarna 110. Sasom visas i fig. 7 och 8 ãr nedre anden av vardera linan 111 forbunden med ett mellanstycke 112, som är upphangt i en fritt hangande stang 114, som stracker sig mellan den vanstra och den hagra vagnen. The strap holders or stirrups 110 are lifted to the outer ends of the outriggers by means of ropes 111 fixed in the rope drums 102 and pulled over the front breaking discs 98. Each rope 111 is connected to the side of a carriage for the stirrups 110. As shown in Figs. 7 and 8 the lower spirit of each the rope 111 connected to an intermediate piece 112, which is suspended in a freely hanging rod 114, which extends between the left and the right carriage.

En detalj i traversvagnen visas i fig. 12. I vardera anden av stangen 114 dr fast ett kort, rektangulart organ 115. Mellan varje mellanstycke 112 och ett organ 115 uppbar stangen 114 en rulle 116. Vartdera organets 115 yttre ande har en axeltapp 117, som uppbar en rulle eller skiva 118. A detail of the traverse carriage is shown in Fig. 12. In each end of the rod 114 there is attached a short, rectangular member 115. Between each intermediate piece 112 and a member 115 the rod 114 carried a roller 116. Each outer spirit of the member 115 has a shaft pin 117, which carried a roll or disc 118.

Stangen 114 uppbar owe anden av ett par barflansar 120 for vardera bygeln 110. Den nedre anden av varje par barflansar slutar i en speciellt utformad, i hajdled installbar bygeldel 121 far uppbarande av ett ovulkat dacksband. Varje bygeldel kan eventuellt vara forsedd med ett sakerhetsstopp 123. Sedan stangen 114 och byglarna 110 ha lyfts till utliggarorganens ytterande rara sig traversvagnarna mat fran skivorna 97. The rod 114 supported the spirit of a pair of bare flanges 120 for each bracket 110. The lower spirit of each pair of bare flanges terminates in a specially designed, height-adjustable bracket portion 121 which is supported by an unvulcanized dacks band. Each stirrup part may optionally be provided with a safety stop 123. Since the rod 114 and the stirrups 110 have been lifted to the outside of the outrigger means, the traverse carriages move food from the discs 97.

Sasom visas i fig. 9 och 10 är pa insidan av varje sidobalk 91 fast en serie distansstopp 124, som uppbara en skena 125. Denna ar lampligen nagot smalare an kedjans 105 lankrullar. Dd traversen av linorna 111 drages mot beskickningsmekanismerna 35, ga_ rullarna 116 upp pa de rorliga kedjelankarna 105, som understadjas av skenorna 125, samt fora stangen 114 och byglarna 110 till beskickningsmekanismerna. Traversvagnens rorelse stabiliseras av rullarna 118, som rulla mot undersidan av horisontella flansar pa vardera sidobalken 91. As shown in Figs. 9 and 10, on the inside of each side beam 91 is fixed a series of spacer stops 124 which support a rail 125. This is suitably slightly narrower than the long rollers of the chain 105. As the traverse of the ropes 111 is pulled towards the loading mechanisms 35, the rollers 116 ascend on the movable chain anchors 105, which are supported by the rails 125, and lead the rod 114 and the stirrups 110 to the loading mechanisms. The movement of the traverse carriage is stabilized by the rollers 118, which roll towards the underside of horizontal flanges on each side beam 91.

Transportoren 90 verkar pa foljande salt. Ett ovulkat dack fran en icke visad frammatningsapparat placeras i transportbygeln 110, medan denna star i sitt nedersta lage. Detta tillstand visas i fig. 7 Transportormotorn 104 startas sedan for att driva axeln 100 medurs sett i fig. 7. Traversvagnen lyftes genom att linorna 111 rullas upp pa lintrummorna 162 och fares till den yttre Bilden av utliggarorga nen. Da traversvagnen nar deras ytterande, komma dess rullar 116 till kontakt med den drivna kedjans 105 lankar, sâ att en jamn rorelse upp pa och Over de framre skivorna 97 majliggares. De rorliga kedjelankarna 105 dra sedan traversvagnen under den slutliga rOrelsen till beskickningsmekanismerna 35. Conveyor 90 operates on the following salt. An unvulcanized tire from a feed apparatus (not shown) is placed in the transport bracket 110, while this is in its lowest position. This condition is shown in Fig. 7. The conveyor motor 104 is then started to drive the shaft 100 clockwise as shown in Fig. 7. The traverse carriage is lifted by rolling the ropes 111 onto the rope drums 162 and moving them to the outer image of the outriggers. As the traverse carriage reaches their outer edge, its rollers 116 come into contact with the links of the driven chain 105, so that a smooth movement up on and over the front discs 97 is possible. The movable chain anchors 105 then pull the traverse carriage during the final movement to the loading mechanisms 35.
