Description

466 255 - fig. 5 schematiskt visar ett längssnitt genom en första utföringsform av en kassett enl. uppfinningen, - fig. 6 schematiskt visar ett längssnitt av en del av ett arrangemang vid köttpackning med användande av en kassett enl. uppfinningen, samt - fig. 7 schematiskt visar ett stycke kött förpackat i ett stycke strumpa av nät. 466 255 - Fig. 5 schematically shows a longitudinal section through a first embodiment of a cassette according to Fig. 6 schematically shows a longitudinal section of a part of an arrangement in meat packing using a cassette according to the invention, and - Fig. 7 schematically shows a piece of meat packed in a piece of sock of net.

I fig. Ä betecknas med 1 en strumpa av nät, där strumpans 1 längd är avsedd att vara ett stort antal gånger större än dess vidd och där, såsom vid för- packning av kött 2,schematiskt visat i fig. 6 och 7, en lämplig strumplängd 1' är avsedd att avskiljas och förslutas i sina båda ändar 1" och där läng- der I' av strumpa 1 sålunda är avsedda att successivt avlägsnas från strum- pan i.In Fig. Ä, 1 denotes a sock of net, where the length of the sock 1 is intended to be a large number of times greater than its width and where, as in the case of packaging of meat 2, schematically shown in Figs. 6 and 7, a suitable sock length 1 'is intended to be separated and closed at its two ends 1 "and where lengths I' of sock 1 are thus intended to be successively removed from the sock i.

En anordning, såsom enl. fig. 4, för framställning av en anordning med strumpa av nät är avsedd att förses med strumpa från ej visade magasin. Ett sådant magasin kan bestå av en rulle,hos vilken successiva varv av strumpa är lindade på varandra, så att strumpans längsled löper i rullens omkrets- led.A device such as acc. Fig. 4, for the manufacture of a device with a sock of nets is intended to be provided with a sock from magazines (not shown). Such a magazine may consist of a roller, in which successive turns of the sock are wound on each other, so that the longitudinal direction of the sock runs in the circumferential direction of the roller.

Anordningen förefínns för att utbilda en kassett 3, fig. Ä, 5 och 6, av strumpa 1 tillsammans med en rörformig kropp Å, såsom ett rör av papper el- ler plast, hos vilken kassett 3 strumpa förefínns påförd kroppen Å, vilken härvid är anordnad invändigt i strumpan. Anordningar förefínns härvid för att packa strumpan på kroppen.The device is provided for forming a cassette 3, Figs. Ä, 5 and 6, of sock 1 together with a tubular body Å, such as a tube of paper or plastic, in which cassette 3 sock is present applied to the body Å, which in this case is arranged inside the sock. Devices are provided for packing the sock on the body.

Vid den visade utföringsformen förefínns för packning av strumpan på krop- pen organ 5, fig. 1, 2 och Å, anordnade att samverka med strumpan vid fle- ra ställen i omkretsled hos strumpan samt att utföra en fram- och återgåen- de rörelse i kroppens längsled, såsom visas med pilen 6, fig. Å, där dock ej rörelsens storlek explicit anges. Nämnda organ 5 är av sådant slag att de är anordnade att ingripa i strumpan genom att haka i densamma då nämnda organ 5 förs i riktning mot redan packad strumpa eller motsvarande läge, d.v.s. nedåt i fig. Å, i medbringande och packande syfte samt att nämnda organ är anordnade att ej ingripa i strumpan då de förs åt motsatt håll.In the embodiment shown, for packing the sock on the body means 5, Figs. 1, 2 and Å, are arranged to cooperate with the sock at several places in the circumferential direction of the sock and to perform a reciprocating movement in the longitudinal joint of the body, as shown by the arrow 6, Fig. Å, where, however, the size of the movement is not explicitly stated. Said means 5 are of such a nature that they are arranged to engage in the sock by hooking in it when said means 5 are moved in the direction of already packed sock or corresponding position, i.e. downwards in Fig. Å, for carrying and packing purpose and that said means are arranged not to engage in the sock when they are moved in the opposite direction.

Enl. den visade utföringsformen förefínns en med längsgående spår 7 för- sedd trumma 8, via vilken strumpa tillförs och över vilken strumpan 1 löper, vilka spår 7 är väsentligen parallella med nämnda kropps Å Iängsled. Föredra- get är härvid ofta att nämnda organ 5 utgörs av flikar, fingrar eller lik- ¿i 466 '255 nande organ, vilka är lutande i riktning mot redan packad strumpa eller motsvarande läge, så att strumpan glider av nämnda organ 5 och så att de hakar i strumpan 5 då nämnda organ förs i riktning från resp. mot redan packad strumpa eller motsvarande läge, varvid nämnda organ med ett yttre parti 5' insticker i nämnda spår 7 och härvid är anordnade att samverka med nämnda spår.According to. In the embodiment shown, there is a drum 8 provided with longitudinal groove 7, via which sock is supplied and over which sock 1 runs, which grooves 7 are substantially parallel to said longitudinal joint of said body. It is often preferred here that said means 5 consist of flaps, fingers or similar means, which are inclined in the direction of already packed sock or corresponding position, so that the sock slides off said means 5 and so that they hook in the sock 5 when said means are moved in the direction from resp. against an already packed sock or corresponding position, wherein said means with an outer portion 5 'protrude into said groove 7 and are hereby arranged to cooperate with said groove.

I ﬁg.l-4 visas en föredragen utföringsform av trumma 8. Trumman 8 inne- fattar härvid en väl avrundad ingångsände 9, vid vilken strumpa ínlöper på trumman. Mellan ingångsänden 9 och trummans matningsparti 10, vilket företrädesvis har väsentligen cylindrisk konfiguration och från vilket strumpa matas till nämnda kropp medelst organen 5, förefinns ett från änden 9 sig vidgande och i partiet 10 övergående anslutningsparti 11 av väsentligen konisk konfiguration. Föredraget är att matningspartiet har en omkrets, vilken påtagligt överstiger omkretsen hos strumpan i strum- pans opåverkade tillstånd, varvid det förutsätts att strumpan är i till- räckligt hög grad töjbar och fjädrande.In ﬁ g.l-4 a preferred embodiment of drum 8 is shown, the drum 8 here comprises a well-rounded entrance end 9, at which sock runs into the drum. Between the entrance end 9 and the feed portion 10 of the drum, which preferably has a substantially cylindrical configuration and from which sock is fed to said body by means of the means 5, there is a connecting portion 11 of substantially conical configuration extending from the end 9 and passing into the portion 10. It is preferred that the feed portion has a circumference which substantially exceeds the circumference of the sock in the unaffected state of the sock, it being assumed that the sock is sufficiently extensible and resilient.

Vid den i fig. Å visade utföringsformen av anordning förefinns tvenne trummor 8, såsom ett exempel vertikalt anordnade, varvid tvenne kasset- ter 3 kan åstadkommas samtidigt. Anslutande till en trummas utgångsände 12 förefinns en stativanordníng 13, anordnad att uppbära en kropp ü för påförande av strumpa medelst organ S, vilka organ här är anordnade på ett för båda trummorna gemensamt bärdon lä anordnat att medelst lämpli- ga anordningar, såsom en pneumatiskt eller hydraulískt manövrerad cy- linder 15, utföra nämnda fram- och återgående rörelse på uppenbart sätt.In the embodiment of the device shown in Fig. Å, two drums 8 are present, as an example vertically arranged, whereby two cassettes 3 can be produced simultaneously. Adjacent to the outlet end 12 of a drum there is a frame device 13, arranged to support a body ü for applying sock by means S, which means are arranged here on a carrier common to both drums and arranged to be arranged by means of suitable devices, such as a pneumatic or hydraulically actuated cylinder 15, perform said reciprocating movement in an obvious manner.

Förfarandet enl. uppfinningen, liksom funktionen hos anordningen enl. uppfinningen torde till väsentlig del framgått ovan. Strumpa påföres så- ledes en rörformig kropp, där strumpan packas på kroppen, varvid en kas- sett åstadkommes. Vid den visade utföringsformen påförs strumpa via trum- man med spåren 7, vilka överbryggas av strumpans nätgarn eller motsvaran- de, varvid organen 5 kan föras förbi nämnda garn då organen har en lutan- de yta 5" i kontakt med garnet och garnet härvid glider av och varvid or- ganen hakar i och medbringar garnet då möjlighet att glida av ej ges till följd av organets 5 form. Nämnda garn 1"' med ungefärligt läge har inri- tats prickat i den nedre högra kvadranten i fig. 1, där i omkretsled lö- pande delar av garnet utritats. 466 255 , Såsom torde framgått ovan erbjuder uppfinningen synnerligen väsentliga för- delar jämfört med tidigare känd teknik. Sålunda medger användande av kasset- ten väsentliga tidsbesparingar under det att förfarandet och anordningen för utförande av förfarandet medger mycket ändamålsenlig framställning av kassetter.The procedure according to the invention, as well as the function of the device according to the invention should be substantially apparent from the foregoing. The sock is thus applied to a tubular body, where the sock is packed on the body, whereby a cassette is provided. In the embodiment shown, a sock is applied via the drum with the grooves 7, which are bridged by the net yarn of the sock or the like, whereby the means 5 can be passed past said yarn when the means have an inclined surface 5 "in contact with the yarn and the yarn thereby slides and the means hooking in and bringing the yarn then the opportunity to slide off is not given due to the shape of the member 5. Said yarn 1 "'with approximate position has been arranged dotted in the lower right quadrant in Fig. 1, where in circumferential running parts of the yarn have been drawn. 466 255. As will be seen above, the invention offers extremely significant advantages over the prior art. Thus, the use of the cassette allows significant time savings while the method and apparatus for performing the method allows for very efficient production of cassettes.

Ovan har uppfinningen beskrivits i anslutning till i huvudsak en utförings- form. Naturligtvis kan fler utföringsformer och mindre förändringar tänkas, utan att uppfinningstanken därför frångås.The invention has been described above in connection with essentially an embodiment. Of course, more embodiments and minor changes are conceivable, without departing from the spirit of the invention.

Sålunda behöver den rörformiga kroppen ej ha väsentligen cirkulärt tvär- snitt. Kroppen kan framställas av exempelvis papper, plast eller metall.Thus, the tubular body need not have a substantially circular cross-section. The body can be made of, for example, paper, plastic or metal.

Antalet i omkretsled anordnade organ 5 kan naturligtvis varieras inom vida gränser. Antalet organ kan sålunda vara betydligt färre än enl. fig. l. Or- ganens funktion kan uppnås på flera sätt. Sålunda kan i radiell led hos trumman förskjutbara organ tänkas, vilka härvid införs i riktning mot trum- man för ihakande samverkan med strumpan då avsikten är att medbringa och packa strumpan samt utdrages för att ej medbringa strumpa då de förs i riktning från redan packad strumpa.The number of circumferentially arranged members 5 can of course be varied within wide limits. The number of organs can thus be significantly less than according to Fig. 1. The function of the organs can be achieved in several ways. Thus, in the radial direction of the drum, displaceable members are conceivable, which are hereby inserted in the direction of the drum for continuous cooperation with the sock when the intention is to bring and pack the sock and are pulled out to not bring sock when they are moved in the direction of already packed sock.

Beträffande arrangemangen l3,lÅ,15 för uppbärande av kropp/'ar 4 och suc- cessiv packning av strumpa på nämnda kropp/-ar kan sägas att dessa natur- ligtvis kan utformas på flera sätt. Enligt ett utförande förefinns ett stöddon 16 på vilket kroppen Ä stöder och inledningsvis vid packningen förefinns i anslutning till trumman 8, varvid kroppen med en del lämp- ligen uppsticker i trumman, och vilket stöddon är, på ej visat sätt, mot en bromskraft eller motsvarande förskjutbart i riktning från trumman, så att stöddonet under inverkan av vid packningen utövad från trumman riktad kraft stegvis förskjuts i riktning från trumman under det att strumpa successivt packas på kroppen 4.Regarding the arrangements 13, 10, 15 for supporting body (s) 4 and successive packing of sock on said body (s), it can be said that these can of course be designed in several ways. According to one embodiment, there is a support device 16 on which the body Ä rests and initially at the packing is present in connection with the drum 8, the body with a part suitably protruding into the drum, and which support device is, in a manner not shown, against a braking force or equivalent displaceable in the direction from the drum, so that under the influence of the force exerted from the drum during the packing, the support device is gradually displaced in the direction from the drum while the sock is successively packed on the body 4.

Uppfinningen skall således ej anses begränsad till ovan angivna utförings- former utan kan varieras inom dess av bifogade patentkrav angivna ram.The invention is thus not to be considered limited to the above-mentioned embodiments but can be varied within the scope specified by the appended claims.
