Opfindelsen angår et apparat til emballering af varer, navnlig en sammentrykt stabel isolationsmåtter, i en pose eller seek, omfattende et pakkenæb, gennem hvilket stabelen føres til bunds i posen, efter at den-5 nes åbne ende er forskudt et stykke ind på næbbet omkring dettes fri ende, og en foran pakkenæbbets fri ende og sideforskudt i forhold hertil anbragt mekanisme til modtagelse af hovedsagelig parallelt med pakkenæbbet fremførte, fladlagte poser, hvilken meka-10 nisme har to til fangning af hver sin posesidevæg tjenende holdere, der er bevægelige bort fra hinanden til åbning af posen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for packaging goods, in particular a compressed stack of insulation mats, in a bag or sack, comprising a packing bead through which the stack is inserted to the bottom of the bag after its open end is displaced a bit into the beak about its free end and a front end of the package beak and laterally displaced in relation thereto, for receiving substantially flattened bags provided parallel to the package beak, the mechanism having two holders for each of their bag side wall movable away from each other to open the bag.

Emballering af mineraluldplader ved brug af et pakkenæb har været anvendt gennem en årrække på den må-15 de, at højden af stabelen først reduceres med op mod 50%, hvorefter stabelen presses frem gennem pakkenæbbet, efter at en på forhånd fremstillet pose eller sæk ad manuel vej er trukket ind på dette næb, så at den kan modtage den sammenpressede stabel, uden at denne 20 atter får lejlighed til at udvide sig nævneværdigt i højderetningen. Under stabelens fortsatte forskydning frem gennem næbbet trækker den sækken fri af dette, hvorefter den åbne ende af sækken kan lukkes ved svej s-ning eller tilsnøring. Den manuelle betjening af pakke-25 næbbet kræver meget mandskab, men dette kan der i betydelig grad rådes bod på ved brug af den omtalte mekanisme til modtagelse og åbning af poserne.Packaging of mineral wool sheets using a packet bacon has been used for a number of years in that the height of the stack is first reduced by up to 50%, after which the stack is pushed forward through the package bacon after a pre-made bag or bag manual path has been drawn in on this beak so that it can receive the compressed stack without giving this 20 opportunity again to expand significantly in height. During the continued displacement of the stack through the beak, it pulls the sack free of this, after which the open end of the sack can be closed by welding or sewing. The manual operation of the package-25 beak requires a great deal of manpower, but this can be remedied to a considerable extent by the use of the mentioned mechanism for receiving and opening the bags.

Formålet med den foreliggende opfindelse er at anvise et apparat, der med et minimum af betjening 30 muliggør en forøgelse af dets pakkekapacitet.Med henblik herpå er apparat ifølge opfindelsen ejendommeligt ved en mellem modtagemekanismen og pakkenæbbet bevægelig medbringer med gribere til aftagning af den åbnede pose fra holderne og overføring af posen til en stil-35 ling ud for pakkenæbbet samt indføring af posen på dette.The object of the present invention is to provide an apparatus which, with a minimum of operation 30, allows an increase in its packing capacity. For this purpose, the apparatus according to the invention is peculiarly movable with grippers for removing the opened bag from the receiving mechanism and the packing beak. the holders and transfer of the bag to a post next to the package beak and insertion of the bag thereon.

Ved brug af dette apparat anvendes der altså på forhånd færdiggjorte poser eller sække, der, uden at det bliver økonomisk uforsvarligt, kan fremstilles i en sådan kvalitet, at de uden sprængningsrisiko kan 5 tåle det ganske kraftige, indvendige tryk, som den stærkt komprimerede stabel udøver, og der bliver ikke behov for en efterfølgende krympning, selv om en sådan eventuelt kan komme på tale i specielle tilfælde.Thus, when using this apparatus, pre-made bags or sacks are used which, without being economically unenforceable, can be manufactured to such a degree that they can withstand the very strong internal pressure of the highly compressed stack without the risk of bursting. exercise, and no subsequent shrinkage is required, although this may be the case in special cases.

Den tilstræbte kapacitetsforøgelse er opnået 10 ved, at allerede medens én pose er på vej til pakkenæbbet, kan en næste pose modtages og åbnes af holderne, og medens den første pose fyldes og derefter bringes fri af pakkenæbbet, kan medbringeren gå tilbage til modtagemekanismen og hente den næste, 15 allerede åbnede pose eller sæk.The desired increase in capacity is achieved by the fact that while one bag is already on its way to the package beak, a next bag can be received and opened by the holders, and while the first bag is filled and then released from the package beak, the carrier can return to the receiving mechanism and retrieve the next, 15 already opened bag or sack.

Yderligere enkeltheder ved apparatet ifølge opfindelsen er i det følgende nærmere forklaret under henvisning til tegningen, der viser et forenklet sidebillede af en udførelsesform for dette apparat til emballe-20 ring af en stabel komprimerede isolationsmåtter i en plastsæk.Further details of the apparatus according to the invention are explained in more detail below with reference to the drawing, which shows a simplified side view of an embodiment of this apparatus for packaging a stack of compressed insulation mats in a plastic bag.

En fladlagt rørfolie 1 aftrækkes fra et ikke vist forråd, såsom en magasinrulle, og ledes mellem et par svejse- og afskæringskæber 2 frem til en mekanisme 25 med to par over hinanden beliggende holdere 3 og 4 med sugemundstykker til fangning af rørfoliens to modstående sidevægge tæt ved foliens forreste ende. Herefter aktiveres kæberne 2 til frembringelse af en tværliggende svejsesøm 5, og den herved færdiggjorte sæk 30 6 adskilles fra den efterfølgende del af rørfolien 1 og åbnes ved, at det nederste par holdere 4 sænkes til 3 146335 den med 4' markerede stilling under medtagning af den nedre posesidevæg.A flattened pipe foil 1 is pulled from a stock not shown, such as a magazine roller, and is passed between a pair of welding and cutting jaws 2 to a mechanism 25 with two pairs of superposed holders 3 and 4 with suction nozzles for catching the two opposite side walls of the pipe foil at the front end of the foil. Thereafter, the jaws 2 are activated to produce a transverse weld seam 5, and the finished bag 30 6 is separated from the subsequent part of the tube foil 1 and opened by lowering the lower pair of holders 4 to the 4 'position marked with the inclusion of the the lower bag side wall.

Foran modtagemekanismen med holderne 3 og 4 er der anbragt en medbringer i form af en vogn eller slæde 5 7, der er reciprocerbar i lodret retning ved hjælp af et kædetræk 8, som er ført over øvre og nedre kædehjul 9 og 10, af hvilke det øverste kan være drevet som antydet med den indtegnede dobbeltpil. Medbringeren har to sæt gribere 11, der fra den med punkteret streg 10 viste hvilestilling kan svinges ind i den åbne ende af sækken 6, hvorved dennes mundingsparti udspiles til rektangulær form og fastholdes af griberne 11. Efter ophævelse af undertrykket i sugemundstykkerne hørende til holderne 3 og 4 bevæges medbringeren 7, 11 15 nedad, indtil sækken befinder sig ud for et pakkenæb 12, og straks efter tilbageføring af de nedre holdere til disses udgangsstilling kan en næste plastsæk 6 gøres klar som foran forklaret.In front of the receiving mechanism with the holders 3 and 4 is arranged a carrier in the form of a carriage or carriage 5, which is reciprocally vertical by means of a chain pull 8 which is passed over upper and lower sprockets 9 and 10, of which the the top can be driven as indicated by the double arrow drawn. The carrier has two sets of grippers 11 which, from the resting position shown by the dashed line 10, can be swung into the open end of the bag 6, whereby its mouth portion is played out in rectangular shape and held by the grippers 11. After lifting the vacuum in the suction nozzles belonging to the holders 3 and 4, the carrier 7, 11 15 is moved downward until the bag is facing a packing lug 12 and immediately after returning the lower holders to their starting position, a next plastic bag 6 can be made ready as explained above.

Pakkenæbbet 12 har et ikke vist stativ med øvre 20 og nedre, endeløse bånd 13, der løber i de ved pilene angivne retninger, og hvis baner er bestemt af lede- og venderuller 14 og 15. De fremadløbende, indre båndparter konvergerer mod hinanden i hvert fald frem til lederullerne 14 og eventuelt helt frem til venderul-25 lerne 15 og er herved medvirkende til lodret komprimering af den stabel mineraluldmåtter 16, der skal emballeres.The packing rib 12 has a not shown frame with upper 20 and lower endless strips 13 running in the directions indicated by the arrows, and whose trajectories are determined by guide and turning rollers 14 and 15. The forward, inner band pairs converge towards each other. falls to the guide rollers 14 and, optionally, all the way to the rollers 25 and thereby contributes to vertical compression of the stack of mineral wool mats 16 to be packaged.

Efter at medbringeren 7, 11 med den åbne sæk 6 er bragt i stilling foran pakkenæbbet 12 som foran 30 forklaret, aktiveres en pneumatisk cylinder 17, hvorved kædetrækket 8's nedre kædehjul 10 forskydes fremad parallelt med pakkenæbbet 12 og derved fører den åbne ende af sækken ind på dette pakkenæb. Ved dettes ydersider er der anbragt omløbende friktionsbånd 18, 35 f.eks. børstebånd, der løber kontinuerligt i de ved pilene angivne retninger og ved hjælp af pneumatiske drev 19 kan bevæges imod eller bort fra pakkenæbbet. I medbringerens forskudte stilling vil friktionsbåndene 18After the carrier 7, 11 with the open bag 6 is positioned in front of the packing beak 12 as explained in front of 30, a pneumatic cylinder 17 is activated, whereby the lower sprocket 10 of the chain pull 8 is displaced forwardly parallel to the package beak 12 and thereby introduces the open end of the bag. on this package name. At its outer sides, circumferential friction bands 18, 35 are provided, e.g. brush bands running continuously in the directions indicated by the arrows and by means of pneumatic drives 19 can be moved towards or away from the package beak. In the staggered position of the carrier, the friction bands 18

Claims

146335 together with the outside receding portions of the package beak 13 catch the mouth of the bag 6, which is then released from the carrier by swinging its grippers 11, after which the bag is pulled or swept into the beak and possibly smoothed out along it. In this way, when the bag 6 has been delivered to the package beak 12, the carrier 7, 11 returns to the position shown in the drawing, and the front stack 10 mineral wool mats 16 in the bag beak 12 are moved forward to abut against the played bottom of the bag 6 and further forward. so that the sack is pulled free of the beak. Including the filled bag falls on a belt conveyor 2p, and when it is completely released from the beak 12 and removed from it, a next bag can be fed to the beak in the same manner as explained above.
