Uppfinnare: P F Brielde Prioritet begtird frdn den 20 maj 1959 (USA) FOreliggande uppfinning avser en apparat fOr stapling av dukmaterial, speciellt sadana fOremal av dukmaterial som pasar av tunn polyenduk, medan pasarna avges direkt Iran pastillverkningsmaskinen. Inventor: P F Brielde Priority Begdird of May 20, 1959 (USA) The present invention relates to an apparatus for stacking cloth materials, especially such objects of cloth materials which fit thin polyene cloth, while the passes are delivered directly to the Iran pastel making machine.

Utmarkande for staplingsapparaten enligt uppfinningen är att foremalen i foljd .avgives till staplingsapparaten i plant tillstand och upplangda i ett i huvudsak vertikalt plan, att stapelformningsorgan ãr anordnade och innefattar ett flertal tappar, anbragta sa, att de är vanda mot foremalen vid avgivningsstallet samt lateralt intill dessa, att ett staplingshuvud Sr anbragt for rorelse mot tapparna for att gripa foremalen och spetsa dessa pa tapparna samt att organ är anordnade for drivning av staplingshuvudet i takt med mottagandet av fOremalen. Characteristic of the stacking apparatus according to the invention is that the foremal is subsequently delivered to the stacking apparatus in a flat condition and suspended in a substantially vertical plane, that stacking means are arranged and comprise a plurality of pins, arranged so as to be accustomed to the foremal at the delivery site and laterally adjacent. these, that a stacking head is arranged for movement against the pins to grip the foremale and point these on the pins and that means are arranged for driving the stacking head in step with the reception of the preform.

Medelst apparaten erhalles en jamn och symmetrisk, vertikal stapel av foremal, varvid foremalen upphanges pa horisontella tap-par, som bildar en upphangningsanordning. By means of the apparatus a smooth and symmetrical, vertical stack of objects is obtained, whereby the objects are suspended on horizontal taper pairs, which form a suspension device.

Apparaten majliggor en forhojd staplingshastighet, som svarar mot en snabb pasmaskinskapacitet. Pasarna omhandertages medan de avges, sa att de direkt och sakert kan overforas till och upphangas pa de tappar, som ar anordnade att mottaga pasarna, med bibehallande av dessas jamnhet och utan stockning i trots av luftturbulens och dennas effekt pa det mjuka, tunna pasmaterialet. The device may have an increased stacking speed, which corresponds to a fast fitting machine capacity. The passports are handled while being dispensed, so that they can be directly and safely transferred to and hung on the pins which are arranged to receive the passports, while maintaining their smoothness and without clogging in spite of the air turbulence and its effect on the soft, thin fitting material.

Apparaten innefattar aven anordningar for lagring av raknade staplar i ett vertikalt lage, vilket medfor inbesparande av utrymme och underlattande av packningen av passtapeln. The apparatus also includes devices for storing shaved stacks in a vertical layer, which results in saving space and facilitating the packing of the fitting stack.

Ehuru uppfinningen kan utforas pa varie, rande satt och erbjuder alternativa konstruk, tionsnaajligheter, visas i ritningarna och besknives n.edan i detalj en enda utforingsform. Uppfinningen avses icke begransad till den visade, speciella utforingsformen, utan avseS skola innefatta alla modifikationer, alternativa konstruktioner och ekvivalenta utforingsformer, som faller Mom ramen for uppfinningens grundtanke. Although the invention may be embodied in various ways and offers alternative constructions, possibilities, are shown in the drawings and a single embodiment is described in detail below. The invention is not intended to be limited to the particular embodiment shown, but is intended to include all modifications, alternative constructions and equivalent embodiments which fall within the scope of the basic idea of the invention.

Staplingsapparaten enligt uppfinningen innefattar ett stativ 10 av jarnprofiler, som Os anordnat att fastas pa golvet intill en pasmaskin 11, av vilken en del visas schematiskt i fig. 2. Staplingsapparaten ar anordnad att direkt mottaga de frill pasmaskinen av- Dupl. kl. 54 a: 3/04 2— — givna pasarna saint staplar de fardiga pasarna 13, .som avlamnas i foljd i ett plant, i hiivudsak vertikalt lage .samt upphangda och inomentant stannade (sasom visas i fig. 1) i avgivningsogonblicket. Pasarna avskiljes frau den kontinuerliga duken 15 medelst knivar 161 pasmaskinen 11, sasom visas schematiskt i fig. 2. Vid ett .sadant arrangemang och da det galler pasar tillverkade av polyetenfilm, kan den nedre, framre anden 17 av pasen ha varmforseglats vid pasmaskinens huvud 18 och pasens sidor 19 vikts, om pasen är av den visade typen, som. tillverkats av en kontinuerlig, rorformig duk. The stacking apparatus according to the invention comprises a stand 10 of iron profiles, which Os is arranged to be fixed on the floor next to a fitting machine 11, a part of which is shown schematically in Fig. 2. The stacking apparatus is arranged to directly receive the frill fitting machine from Dupl. at 54 a: 3/04 2— - given passes saint stacks the finished passes 13, which are unloaded in succession in a plane, essentially vertically low, as well as suspended and internally stopped (as shown in Fig. 1) at the moment of delivery. The calipers are separated from the continuous fabric 15 by means of knives 161 of the caliper 11, as shown schematically in Fig. 2. In such an arrangement and when the calipers are made of polyethylene film, the lower, front end 17 of the caliper may have been heat sealed to the caliper head 18. and the sides 19 of the passport are folded, if the passport is of the type shown, as. made of a continuous, rudder-shaped cloth.

Pa grund av pasmaterialets mjukhet och latthet liar manga svarigheter upptratt vkl hittills kanda staplingsapparater vid behandlingen och Overforingen av pasarna. De avgivna pasarna har vanligen tagits en och en. och placerats pa en horisontell stapel. Genom foreliggande uppfinning overvinnes de vid stapling av pasarna upptradande svarigheterna, varvid pasarna far bibehalla det vertikala 'age, i vilket de avges, samt over-bares i det vertikala laget och upphanges pa horisontella tappar, som bildar upphingningsanordningar. Due to the softness and lightness of the fitting material, many similarities have occurred so far known stacking devices in the processing and transfer of the fitting. The issued passports have usually been taken one by one. and placed on a horizontal bar. The present invention overcomes the difficulties encountered in stacking the passers, allowing the passers to maintain the vertical age in which they are delivered, as well as being conveyed in the vertical layer and suspended on horizontal pins forming suspension devices.

For att styra och häila pasen i ett vertikalplan vid avgivningsogonblicket begagnas ett luftavgivningsarrangemang, varvid vertikala hiftstrommar 20 riktas nedat pa vardera sidan av pasen, da denna framkommer fran pa.smaskinen och matas direkt in i staplingsapparaten. LuftstrOmmarna hAiler pasen i ett huvudsak vertikalt, plant lage och forhindrar, att pasen svanger okontrollerat, medan den matas nedat och in i staplingsapparaten. Vid en typisk installation matas pasarna med en. hastighet av 200 stycken per minut eller snabbare, sa. att materialet far en utomordentligt hOg linjar hastighet, medan det avges. Eftersom pasens nedre dude varmforseg.1ats sa nar som pa en liten oppning 21 vid pasens hals, tvingas knappast flagon luft in mellan pasens sidor 19, och som kan forsatta denim i rorelse. Emellertid underlattar luftavgivningssystemet avgivandet av pasarna till staplingsapparaten och bibehaller desamma -vertikalt, sA att de kan tagas upp och placeras pa apparatens upphangningsanordningar. In order to guide and heal the passes in a vertical plane at the moment of delivery, an air delivery arrangement is used, wherein vertical lifting drums 20 are directed downwards on each side of the passes, as this emerges from the machine and is fed directly into the stacking apparatus. The air currents hold the pass in a substantially vertical, flat position and prevent the pass from swinging uncontrollably, while it is fed downwards and into the stacking apparatus. In a typical installation, the passes are fed with one. speed of 200 pieces per minute or faster, said. that the material gets an extraordinarily high lines speed while emitting. Since the lower dude of the passport is hot-sealed, such as on a small opening 21 at the neck of the passport, flake air is hardly forced in between the sides 19 of the passport, and which can keep the denim in motion. However, the air delivery system facilitates the delivery of the passes to the stacking apparatus and maintains them vertically so that they can be picked up and placed on the suspension devices of the apparatus.

I enlighet med uppfinningen upphanges pasarna, sedan dessa avgivits till staplingsapparaten i plant, vertikalt lage, successivt pa fran varandra skilda tappar 22, som utgor en upphangningsanordning. Staplingsapparaten innefattar ett staplingshuvud 23 for overforan-de av pasarna, vilket utgores av en vakuumskena 25 (fig. 1), anbragt pa ett horisontellt block 26, som ror sig fram och Ater och vid varje slag medfor en pase till en av de bada -upphangningsanordningarna 27, 28 belagna 'pa vardera sidan av avlamningsstallet. Tapparna 22 stracker sig horisontellt, da de Arc lage for mottagande av pasarna och genom borrar pasmaterialet, da pasen forts till laget for mottagande pa tapparna. Vid varje slag av staplingshuvudet tar detta i enlighet med uppfinningen upp de i foljd avgivna pasarna, hailer desamma medelst vakuum och Over-for pasarna i den ena eller den andra riktningen till den ena av upphangningsanordningarna. Pasarna staplas salunda pa bada upphangningsanordningarna 27, 28, och dessa fores till ett avlastningslage, sedan. de mottagit ett pa forhand bestamt antal pasar. Exempelvis kan 200 eller 500 pasar placeras pa varje upphangningsanordning. I fig. 1 visas den hogra upphangningsanordningen 28 f Orflytta sig till ett avlastningslage. In accordance with the invention, after being delivered to the stacking apparatus, the fittings are suspended in a flat, vertically low, successively spaced apart pins 22, which constitute a suspension device. The stacking apparatus comprises a stacking head 23 for facing the passes, which is constituted by a vacuum rail 25 (Fig. 1), arranged on a horizontal block 26, which moves forward and backward and at each stroke carries a pass to one of the baths - the suspension devices 27, 28 are located on each side of the unloading shed. The pins 22 extend horizontally as the arc prepares for receiving the passes and through drills the pass material as the pass continues to the team for receiving on the pins. At each stroke of the stacking head, in accordance with the invention, it picks up the passes delivered in succession, hails them by means of vacuum and transfers them to the passes in one or the other direction to one of the suspension devices. The fittings are thus stacked on both suspension devices 27, 28, and these are fed to a relief layer, then. they received a pre-determined number of passes. For example, 200 or 500 passes can be placed on each suspension device. Fig. 1 shows the right suspension device 28 f Move to a relief position.

For att gripa och forflytta pasen lateralt ar blocket 26 och vakuumskenan 25, som tillsanamans utgor staplingshuvudet 23, glidbart anbragta for fram- och atergaende rorelse pa borisontella, hardade axlar 30, samt drives medelst en kedja 31, som genom en &Ivanordning ar fi5rbunden med pasmaskinen 11, sa att vagnens rorelse sker synkront med pasarnas avgivande (se fig. 1, 4 och 5). I °eh for anbringning av axlarna 30 pa stativet, ar axlarna gangade vid bagge andarna och fasta medelst muttrar 32, som ar atdragna pa• de gangade andarna vid hallare 33, som är fasta vid stativets stationara vinkeljarn. To grip and move the shafts laterally, the block 26 and the vacuum rail 25, which together form the stacking head 23, are slidably mounted for reciprocating movement on horizontal, hardened shafts 30, and are driven by a chain 31 which is connected to the fitting machine by means of a device. 11, said that the movement of the carriage takes place synchronously with the delivery of the passengers (see Figs. 1, 4 and 5). For mounting the shafts 30 on the stand, the shafts are threaded at the ram ends and fixed by means of nuts 32, which are tightened on the threaded shanks at holders 33, which are fixed to the stationary angle iron of the stand.

Vid den visade utforingsformen utgor ett kamaggregat, innefattande ett par svangbart monterade, i varandra ingripande kammar 31, 34', som uppbares pa vakuumhuvudets iivre kant, en anordning for bibehallande av pasarnas ovre kant plan, medan pasarna spetsas pa upphangningsanordningens tappar. I fig. 1 visas hur pasen tvingas pa tapparna 22. Sasom framgar av denna figur genomborrar upphangningsanordningens tappar 22 pasen mellan intillyarande kamtander. Kam-mama 34, 31' tjanar, da de ar i uppritt att stiklja det tunna, latta material, Ulla det plant och giva det tilräekligt stod for att det pa korrekt satt skall kunna spetsas pa tapparna. In the embodiment shown, a cam assembly, comprising a pair of pivotally mounted, interlocking cams 31, 34 ', which are supported on the upper edge of the vacuum head, constitutes a device for maintaining the upper edge plane of the passes, while the passes are tapered on the pins of the suspension device. Fig. 1 shows how the passes are forced on the pins 22. As can be seen from this figure, the pins 22 of the suspension device pierce the passes between adjacent comb teeth. The combs 34, 31 'serve, as they are in a position to stitch the thin, light material, wool it flat and give it sufficient standing so that it can be properly pointed on the pins.

Vakuumskenan 25 dr delad I mittemot varandra befintliga sidokamrar 38, 39, som omvaxlande evakueras genom en grenledning 40, som ar anbragt under den vanstra sidostativdelen (fig. 1), genom ett par Ha- 42, 43, som stracker sig under den vanstra horisontella stativdelen vid sidan av maskinen. Vardera sidan av vakuumskenan Ar forsedd med rader av oppningar 46, 47 for astadkommande av sugning vid kanterna hos den skena, pA vilken pasarna bares, sO. att pasarna forhindras frau att falla, medan staplingshuvudet fir i arbete. En ventil 49 i vakuumgrenledningen 40 forsattes automatiskt i funktion, da staplingshuvudet nar slagets dude for att hava vakuuet i kammaren och vid oppning- - -3 arna pa skenans ena sida och for att uppratta vakuuet vid den motsatta kammaren och de motsatta Oppningarna pa skenans andra sida, sá att vid vakuumskenans atergangsslag en pase kan tagas upp och med hjalp air vakuuet fans over till den andra upphangningsanordningen. The vacuum rail 25 is divided into opposite side chambers 38, 39, which are alternately evacuated through a branch line 40, which is arranged under the left side frame part (Fig. 1), through a pair of H-42, 43, which extend below the left horizontal the stand part next to the machine. Each side of the vacuum rail Ar is provided with rows of openings 46, 47 for effecting suction at the edges of the rail on which the passes are carried, sO. that the calipers are prevented from falling while the stacking head is at work. A valve 49 in the vacuum manifold 40 was automatically put into operation when the stacking head reaches the dude of the stroke to have the vacuum in the chamber and at the openings on one side of the rail and to establish the vacuum at the opposite chamber and the opposite openings on the other of the rail. side, so that at the return stroke of the vacuum rail a pass can be taken up and even the air vacuum helped fans over to the second suspension device.

De mitt emot varandra befintliga sidokamrarna 38, 39 i den ihaliga skenan astadkommes genom en inre avbalkning i form av en vertikal vagg 61, varvid kamrarna forsattes under vakuum genom grenledningen 40. Forbindelserna till kamrarna utgores i detta fall av de separata vakuumledningarna 42, 43, som leder till grenledningsaggregatet. En enda va.kuumledning 63 leder fran en yttre anordning for astadkommande av vakuum till grenledningen. Vakuumregleringsventilen 49 i grenledningen innefattar en ventilplatta 65, som automatiskt forflyttas mellan de olika lagena vid staplingshuvudets fram- och atergaende rorelse. Vid den visade utforingsf or-men uppbares grenledningen 40 under vakuumskenan, sa att den ror sig tillsammans med den senare, d staplingshuvudet rer sig fram och Ater i och for upptagande och forflyttning av pasarna till upphangningsanordningarna. Ventilplattan 65 skjuter fram fran grenledningen och kommer till ingrepp med en tapp 66, som är fast vid stativet ett kort stycke framfor Linden air staplingshuvudets slag. Vid ingreppet forskjutes ventilplattan 65 horisontellt till sitt motsatta lage, varefter det skjuter fram frail den andra sidan av grenledningen 40 oak kommer till ingrepp med en liknande tapp 67, som uppbares av stativet och traffas av plattan vid en punkt nara anden av returslaget. I fig. 1 visas staplingshuvudet rara sig at hoger, och ventilplattan 65 skjuter fram fran grenledningens framre yta. Bada stopptapparna 66, 67 ligger i den bana, som skall averfaras air ventilplattan och ar sa placerade, att de forskjuter plattan till det motsatta laget. Sasom framgAr av fig. 5 och 8 har ventilplattan 65 en rektangular oppning 69, som farbinder grenledningens framre kammare 70 med den ena eller den andra av de grenledningsforbindelser 42, 43, som leder till vakuumskenan, beroende pa plattans lage. Da plattan är i det hOgra laget, visat i fig. 1, 7 och 8, upprattas genom oppningen 69 vakuum i den hogra kammaren 39 i vakuumskenan 25, sá att skenan medfor en pase, som upptagits vid vagnens rorelse at hoger. Da ventilplattan 65 är det vanstra laget upprattas pa liknande satt vakuum i den vanstra kammaren 38, sd att skenan am i arbete, da vagnen rOr sig at vans-ter. Ventilplattan 65 Mlles i det ena eller det andra av sina arbetslagen medelst en elastisk sparr 71 i ingrepp i ett hack i plattans nedre hant, Oven om ej avsedd forskjutning ay plat-tan kan forhindras pa annat satt. The opposite side chambers 38, 39 in the hollow rail are provided by an inner beam in the form of a vertical cradle 61, the chambers being continued under vacuum through the branch line 40. The connections to the chambers in this case are formed by the separate vacuum lines 42, 43, leading to the branch line assembly. A single vacuum line 63 leads from an external device for providing vacuum to the branch line. The vacuum control valve 49 in the branch line comprises a valve plate 65, which is automatically moved between the different layers during the reciprocating movement of the stacking head. In the embodiment shown, the branch line 40 is supported under the vacuum rail, so that it moves together with the latter, when the stacking head moves forward and Ater in order to receive and move the passes to the suspension devices. The valve plate 65 protrudes from the branch line and comes into engagement with a pin 66, which is fixed to the frame a short distance in front of the stroke of the Linden air stacking head. During the engagement, the valve plate 65 is displaced horizontally to its opposite bearing, after which it protrudes frail the other side of the branch line 40 and comes into engagement with a similar pin 67, which is supported by the frame and struck by the plate at a point near the return stroke. Fig. 1 shows the stacking head moving to the right, and the valve plate 65 protrudes from the front surface of the branch line. Both stop pins 66, 67 are located in the path to be experienced by the air valve plate and are positioned so that they displace the plate to the opposite layer. As shown in Figures 5 and 8, the valve plate 65 has a rectangular opening 69 which connects the front chamber 70 of the manifold to one or the other of the manifold connections 42, 43 leading to the vacuum rail, depending on the bearing of the plate. When the plate is in the right-hand layer, shown in Figs. 1, 7 and 8, a vacuum is established through the opening 69 in the right-hand chamber 39 in the vacuum rail 25, so that the rail carries a pass which is absorbed when the carriage moves to the right. When the valve plate 65 is the leftmost layer, a similarly set vacuum is established in the leftmost chamber 38, so that the rail is in operation when the carriage moves to the left. The valve plate 65 is milled in one or the other of its working layers by means of an elastic latch 71 engaged in a notch in the lower hand of the plate. Although unintended displacement of the plate can be prevented in another way.

For the supporting air stacking head for sliding movement on the pair of hardened shafts 30, a solid block 73 (Figs. 4, 5) is provided and provided with bearings 75, 76 for the shafts. The block 73 carried one second air vacuum rail 25, which in the embodiment shown is suspended as a bracket, so that it is free at the opposite Linden. The block 73 is drilled horizontally to receive hardened bushings or the like, which serve as bearings 75, 76 for support on slidably mounted air blocks on the shoulders. The vacuum rail 25 is supported on the block 73 by a vertical plate 77 which is secured to the block by a plurality of bolts 78. The vacuum rail extends at a right angle to the plate and Hiles horizontally through a web 79 which may have triangular reinforcing ribs 80 shown in elevation in Fig. 8 and is shown mounted on either side of the web and perpendicular to the support plate 77. The vacuum rail and manifold form an assembly shown away from the slidable block 73, which assembly is positioned so that the manifold and tubes are free of the frame. and the drive mechanism, so that the stacking head can move forward and back without obstruction of the transfer of passes from the dispensing layer in the stacking apparatus to the suspensions on the sides of the receiving stall.

In the embodiment shown, by means of the negative pressure in the vacuum rail, the passages are held so that the slope slides down while being transported in the transverse direction. The cams 34, 34 'provide the required additional support.

Sasom ovan namnts liar maskinen en kamskiva 88 for hojande och sankande av karn- — — mama 34, 34' mellan upprattstaende och horisontella lagen, vilken kamskiva upphares ph maskinstativet och samverkar med vevarna 85, 86 som Sr fasta pa andarna av axlarna 82, 83, som svangbart uppbar kammarna. liven om det Sr en fraga om tidsinstallning, som kan varieras fiir anpassning till olika situationer, fEnedrages vanligen, att kammarna hojes under en kort period nara slutet av vakuumskenans slag, och darfor rider vevarna 85, 86 eller kamfoljarna Over det hogre plana partiet 90 av kamskivan, 88 till nara slutet av vakuumskenans slag. 1 detta ogonblick glider den i funktion varande veven 85, 86 nedfor den sluttande kamskivkanten 92 till den nedre horisontella kamskivkanten 93. En fja.der eller annat organ, som i detta fall Or direkt forbundet med veven, kan begagnas for att Valla vevarmen i kontakt med kamskivkanten och for att sakert hoj a kammen till arbetslage. Den nedre horisontella kamskivytan. hailer kammen i vertikalt lage under en period som är tiBrackligt lang for att pasen skall kunna spetsas pa. upphangningsanordningen. Efter staidingslmvudets returslag aterghr den tidigare h5jda kammen till sitt horisontella lage. Nara slutet av slaget i den motsatta riktningen hojes den andra kammen genom den motsatta, i funktion varande kamskivytan och vevfOljaren. As mentioned above, the machine lines a cam disc 88 for raising and lowering the cores 34, 34 'between the upright and horizontal layers, which cam disc is raised on the machine frame and cooperates with the cranks 85, 86 which are fixed to the spirits of the shafts 82, 83. , which pivotally supported the combs. If it is a question of time installation, which can be varied for adaptation to different situations, it is usually assumed that the combs are raised for a short period near the end of the vacuum rail stroke, and therefore the cranks 85, 86 or cam ridges ride over the right flat portion 90 of the cam disc, 88 to near the end of the vacuum rail stroke. At this moment, the operative crank 85, 86 slides down the sloping cam edge edge 92 to the lower horizontal cam disc edge 93. A spring or other means, which in this case is directly connected to the crank, may be used to contact the crank arm. with the cam disc edge and to safely raise the cam to working position. The lower horizontal cam disc surface. hold the comb in a vertical position for a period that is very long so that the pass can be pointed at. the suspension device. After the return stroke of the staidingslmvud, the previously raised ridge returns to its horizontal position. Near the end of the stroke in the opposite direction, the second cam is hoisted through the opposite, operative cam disc surface and crank follower.

The stacking head 23 is advanced horizontally by means of a drive device comprising a spirit chain 31 running around sprockets 95, 97 mounted on the left horizontal frame portion and by a drive link 98 connected to block 73. Shown schematically in Fig. 1 receives in the described embodiment the force for moving the block 73 and thereby the vacuum rail 25 directly from the associated fitting machine 11 through a chain 99, sa. that the time installation of the stacking head's forward and rearward movements can be automatically synchronized with the work of the fitting machine. The forward and return movement of the stacking head 23 can be timed with respect to the reception of the passes, said. that a phase is taken up at each horizontal movement of the vacuum rail and transferred in one or the other direction to one of the suspension devices. Power can be obtained from the phasing machine by means of a chain or belt drive device comprising the chain 99, which Or is arranged to drive a first sprocket or a pulley 101, which is fixed to one end of a drive shaft 103. In the other end of the drive shaft 193 there is one the sprockets 95, which Or is connected directly to the block 73. The Mr feed and feed of the block 73 and the vacuum rail 25 used the spiritless chain 31 carried a connecting link 98, which connects the lead to the stacking head and provides the feed and feed of the latter. For this purpose, as shown in Fig. 5, the connection Milken 98 shows a horizontal pin 102, on the spirit of which there is a roller 104. This roller 104 is received in a vertical groove 105 in a plate 106, which is supported by means of legs 108 at a distance from the block. 73 yta. When the drive device or coupling link 98 moves along the upper loop of the chain (at the left in Fig. 1), the block 73 moves forward due to the engagement between the pin 102 and the sphere 105. When the drive link 98 moves around the left sprocket 95, the pin moves vertically. in the track 105 in the plate, whereby the movement of the block is stopped and the direction of movement is subsequently changed. The clutch link 98 moves At higher in the lower loop of the chain 31 and leads the block 73 to the right end of the stroke, where the block and thus the vacuum rail is stopped and changes direction of movement, while the pin moves to the upper edge of the spare, the clutch link 98, which carried the pin, moves around the sprocket 97.

Vid den visade utforingsformen drives de kedjehjul 95, 97, sorn bar den andlosa kedjan 31 for manovrering av staplingshuvudet, kontinuerligt samt sasona tidigare namnts synkront med pasmaskinen 11, sa. att staplingshuvudet 23 ror sig fram och hter i takt med mottagandet av pasarna, sh att de senare vid mottagningsogonblieket overfores till den ena eller den andra av upphangningsanordningarna. In the embodiment shown, the sprockets 95, 97, driven by the spiritless chain 31 for maneuvering the stacking head, are driven continuously and as previously mentioned synchronously with the fitting machine 11, said. that the stacking head 23 moves and heats up in step with the reception of the passes, that the latter at the moment of reception are transferred to one or the other of the suspension devices.

Upphangningsanordningarna och dessas drivanordning. Upphangningsanordningarna Or anbragta p0 omse sidor om avgivningsplanet for pasarna samt Or sh. placerade, att de genomborrar pasarna, nar dessa overfores medelst staplingshuvudet.

Tydligen .kan staplarna av pasar avlagsnas fran upphangningsanordningarna medan upphangningsanordningen overfores fran det stalle, vid vilket den mottager pasar till laget ovanf8r kedjehjulet. Det kan ocksa vara onskvart att inkludera ytterligare upphangningsanordningar i varje aggregat fOr alining av apparatens lagringskapacitet. Avlagsnandet av staplarna av pasar fran upphangningsanordningarna kan ske automatiskt eller manuellt enligt onskan. The suspension devices and their drive device. The suspension devices Or placed on the sides of the delivery plane for the passers-by and Or sh. placed, that they pierce the passes, when these are transferred by means of the stacking head. As can be seen from Fig. 1, each suspension device comprises a set of pins 22, which are located on a-vs: thud apart in the transverse direction of the stacking apparatus saint Or arranged ph a horizontal holder 115. The pins 22 are supported at approximately the same level. and stretches, as the holder Or in an operative position, in a horizontal direction and points towards the passers-by. The pins 22 or sO are positioned to pass over the vacuum rail 25 between the comb teeth, when the passes, which are held flat and in a vertical plane of one of the combs 34, 34 ', are pierced. The suspension device can be attached to the chains, belts, or other equivalent transport means, which is suitable for suitable salt, which can be used to support the individual suspension devices. As shown, the opposite spirits of the holders 115 are attached to a link in each of the chains, which are wound around the sprockets 117. As shown in Fig. 1, each andos chain can have only a pair of individual suspension devices, so that one suspension device can be placed to receive fits from the stacking head, while the other suspension device is placed for unloading. Apparently, the stacks of passes can be removed from the suspension devices while the suspension device is transferred from the stall at which it receives passes to the team above the sprocket. It may also be inappropriate to include additional suspension devices in each unit for aligning the storage capacity of the apparatus. The removal of the stacks of passes from the suspension devices can be done automatically or manually as desired.

For drivning av kedjehjulen och kedjorna, som bar upphangningsanordningarna Or sa.- som visas i fig. 1 vart och ett av aggregaten medelst en sane kedjehjul- och kedjedrivanordningar forbundna med de axlar, som lamnar kraft till de blocket 73 och den ditpa uppburna vakuumskenan drivande kedjehjulen 95, 97. En envarvssparr 118 ingar i dessa drivhjulverk med en solenoidpaverkningsanordning 119 for manovrering av upphangningsaggregaten, sa att en upphangningsanordning, som bar en stapel av pasar forskjutes och en ej lastad upphangningsanordning fores fram for att mottaga pasarna frail slaplingshuvudet. Solenoidpaverkningsanordningen manovreras i detta fall av ett reglage, som innefattar en raknemekanism (icke visad), som drives av drivanordningen for staplingshuvudet, sa att upphangningsanordningarna automatiskt fOrskjutes f Or avlastning, da ett pa forhand bestamt antal pasar placerats pa upphangningsanordningen. For driving the sprockets and the chains carrying the suspension devices Or sa.- shown in Fig. 1, each of the assemblies is connected by means of a true sprocket and sprocket drive devices to the shafts which leave force to the block 73 and the vacuum rail supported thereon. sprockets 95, 97. A single-speed lock 118 engages in these drive wheels with a solenoid actuator 119 for maneuvering the suspension assemblies, so that a suspension device carrying a stack of passes is displaced and an unloaded suspension device is advanced to receive the passes from the slap head. The solenoid actuating device is in this case operated by a control, which comprises a shaving mechanism (not shown), which is driven by the drive device for the stacking head, so that the suspension devices are automatically displaced for relief, when a predetermined number of passes are placed on the suspension device.

Pi ovan beskriyet satt matar pasmaskinen 11 pasarna direkt till staplingsapparaten, som arbetar synkront med pasmaskinen. Det med hjalp av undertryck arbetande staplingshuvudet tar for varje arbetsslag upp en pase. SO.som tidigare angivits fOrsattes med hjalp av grenledningen 40 en av kamrarna 38, 39 i vakuumskenan 25 under undertryck, beroende pa skenans r8relseriktning. Da skenan under sin rorelse fran den ena upphangningsanordningen till den andra passerar genom avlamningsplanet for pasarna, drager vakuuet, som verkar genom 5ppningarna utefter skenans side, pasen mot skenan och hindrar den frail att falla, medan skenan utfOr silt slag. Tydligen varierar det absoluta trycket i kamrarna i skenan under arbetscykeln. Ventilplattan 65 haver vid slutet av varje slag undertrycket i den kammare, som bar pasen. Pa sa satt frigores pasen, sO. att den f8rblir pa upphangningsanordningens tappar. Samtidigt med att undertrycket haves i den ena av kamrarna (38, 39) i skenan, upprattas vidare undertrycket i den andra kammaren genom att ventilplattan 65 forskjutes till det motsatta laget. Forst, dvs. innan en pase tagits upp, faller trycket i kammaren endast nagot kilogram, eftersom Oppningarna i ske nans sida dr obetackta. Da emellertid vakuumskenan bringas i kontakt med pasen, tacker denna oppningarna och tillsluter elf ektivt kammaren. Trycket i kammaren faller da avsevart under det da radande trycket. Det liar befunnits, att under aterstoden av slaget, dvs. till dess pasen spetsas pa upphangningsanordningstapparna och vakuuet frigjorts, forhlir trycket i kammaren i huvudsak konstant vid det lagre vardet. As described above, the fitting machine 11 feeds the fittings directly to the stacking apparatus, which works synchronously with the fitting machine. The stacking head working with the aid of negative pressure takes up one phase for each type of work. As previously stated, one of the chambers 38, 39 in the vacuum rail 25 was pressurized by means of the branch line 40, depending on the direction of movement of the rail. As the rail during its movement from one suspension device to the other passes through the unloading plane of the rails, the vacuum acting through the openings along the side of the rail pulls the rails against the rail and prevents it from falling while the rail performs a silt stroke. Apparently the absolute pressure in the chambers of the rail varies during the work cycle. At the end of each stroke, the valve plate 65 has the negative pressure in the chamber which carried the pass. Pa sa satt frigores pasen, sO. that it remains on the pins of the suspension device. At the same time as the negative pressure is present in one of the chambers (38, 39) in the rail, the negative pressure in the other chamber is further established by displacing the valve plate 65 to the opposite layer. Forst, ie. before a phase is taken up, the pressure in the chamber drops only a few kilograms, since the openings on the side of the barrel are left unattended. However, when the vacuum rail is brought into contact with the pass, it closes the openings and effectively closes the chamber. The pressure in the chamber then falls considerably below the then radiating pressure. It has been found that during the remainder of the battle, viz. until the pass is tapered on the suspension pin pins and the vacuum is released, the pressure in the chamber remains substantially constant at the lower value.

I enlighet med ytterligare en aspekt ay 18- religgande uppfinning begagnas det la.gre tryeket,(eller hogre vakuumet). i vakuumskenan, som forblir yid ett flit varde, medan pasen bares av skenan, sasom en signal i en kontrollanordning, som upptacker fel i pasmaskinen. For detta andamal Or en fOr tryek reagerande stronastallare 1(fig. 5, 11), som forevarande fall Or en »Mercoid»-vattendifferentialstromstallare av standardtyp, anbragt pa grenledningens 40 vagg, sa att den paverkas av det i kammaren 70 radande trycket, vilket är detsamma som det tryck, som racier i skenans i funktion varande kammare. Stromstallaren 150 Or parallellkopplad med ett par kammanovrerade mikrostromstallare 154, 156 i en i fig. 11 visad krets, som innefattar ett hallrela 162. Kretsen liar till uppgift att varna medelst en alarmanordning 164 och att avstanga pasmaskinen och hjalpapparatur, da ett fel upptacks genom att pasmaskinen lake frammatar en Vase till slaplingsapparaten. For detta andamal Or tryckstrOmstallaren 150 installd att slutas under de intervall av staplingsapparatens normala arbete, da en pase bares av staplingshuvudet. En av de normalt slutna mikrostromstallarna 154, 156 Oppnas momentant am tillhOrande kam 158, 160 under pasmaskinens varje arbetseykel yid det ogonblick, da. tryekstrOmstallaren skall vara sluten pa grund av narvaron ay en. pase, som anligger mot vakuumskenan. Om ett fel skulle intraffa, vilket.anges genom att staplingshuvudet ieke har fla- gon pase, bringar det momentana butandet av kretsen medelst en av de kammar 158, 160, som paverkar tillhOrande stromstallare 154, 156, relaet 162 att slO. ifran, och medelst lampliga regleringsorgan, exempelvis en kretsbrytare, avstanges pasmaskinen och avges en varningssignal. Sasom visas i fig. 4 uppbaras de kammar 158, 160, som man6vrerar mikrostromstallaren 151, 156, av kedjan 31, varigenom stromstallaren kommer att paverkas i korrekt ogonbliek. In accordance with a further aspect of the present invention, the lower pressure (or higher vacuum) is used. in the vacuum rail, which remains at a diligent value while the passport is carried by the rail, as a signal in a control device which detects faults in the passport machine. For this purpose, a pressure-responsive strona switch 1 (Figs. 5, 11), as in the present case, is a standard mercoid water differential switch mounted on the cradle of the branch line 40 so that it is affected by the pressure radiating in the chamber 70, which is the same as the pressure, which racies in the operating chamber of the rail. The current switch 150 is connected in parallel with a pair of cam-operated micro-current switches 154, 156 in a circuit shown in Fig. 11, which comprises a hall relay 162. The circuit has the task of warning by means of an alarm device 164 and of shutting down the fitting machine and auxiliary equipment when a fault is detected by the lake pass machine feeds a Vase to the slapping machine. For this purpose, the pressure switch 150 is set to close during the intervals of the normal operation of the stacking apparatus, when a pass is carried by the stacking head. One of the normally closed microstream stables 154, 156 is momentarily opened at the associated cam 158, 160 during each work cycle of the fitting machine at that moment. The pressure switch must be closed due to the presence of a. phase, which abuts against the vacuum rail. If an error should occur, which is indicated by the stacking head not having a flag pass, the instantaneous blowing of the circuit by means of one of the cams 158, 160 which actuates the associated currenters 154, 156 causes the relay 162 to close. from, and by means of suitable control means, for example a circuit breaker, the fitting machine is switched off and a warning signal is emitted. As shown in Fig. 4, the cams 158, 160, which operate the micro-switch 151, 156, are supported by the chain 31, whereby the switch will be actuated in the correct instant.
