Transportøren 11 drives fortrinnsvis med en hastighet som er større enn den hastighet ved hvilken gjenstandene vandrer under den etterfølgende innpakning for å vedlikeholde en kontinuerlig tilførsel av gjenstander som frammates på samme tid den etterfølgende pakke-anordning, og en skilleanordning av egnet type, som vist ved 12, er anordnet i forhold til transportøren 11 for å atskille gjenstandene som frammates på denne i to rekker. The items to be packed are received at the left end of the frame construction 10, as seen in fig. 1, on a conveyor 11, preferably of the chain type, arranged to have a flat, smooth surface on its upper part or length, on which the objects can slide when bumping against something, but on which the objects will otherwise follow the movement of the conveyor to be brought into the packing operation. The conveyor 11 is preferably operated at a speed greater than the speed at which the objects travel under the subsequent wrapping in order to maintain a continuous supply of objects which are advanced at the same time the subsequent packaging device, and a separating device of a suitable type, as shown at 12, is arranged in relation to the conveyor 11 in order to separate the objects which are advanced on this in two rows.

Over transportøren 11 og i noen avstand fra dens avleveringsende, er anordnet en emnetilførselsanordning 13, som beskrevet i patent nr. 96 202 for å understøt-te et stablet forråd av omslagsemner W av kartong i tverretningen for å mate dem etter hverandre tversover toppen av gjenstandene som skal innpakkes når de føres framad av transportøren 11. Når omslagsemnene W er ført fra utmatningsanordnin-gen 13 overføres hvert emne W til kon-troll av pålegningskjeder, angitt ved 14 i fig. 1, anbragt ved hver side av transpor-tøren 11 og på hvilke atskilte kroker (ikke vist) er anordnet til å legge seg an mot de bakre kanter av de etter hverandre fram-matede emner W for separat seriefram-føring av disse i riktig pakningsstilling med gjenstandene som vandrer på trans-portøren 11. Above the conveyor 11 and at some distance from its delivery end, a blank feeding device 13, as described in Patent No. 96,202, is arranged to support a stacked supply of wrapping blanks W of cardboard in the transverse direction to feed them successively across the top of the articles which are to be wrapped when they are carried forward by the conveyor 11. When the wrapping blanks W have been fed from the discharge device 13, each blank W is transferred to the control of application chains, indicated at 14 in fig. 1, placed at each side of the conveyor 11 and on which separate hooks (not shown) are arranged to rest against the rear edges of the successively fed blanks W for separate serial advancement of these in the correct packing position with the objects traveling on the transporter 11.

De øvre partier eller lengder av pålegningskjedene 14 ligger over transpor-tøren 11 i en slik høyde at de praktisk talt ligger i høyde med toppene av gjenstandene som føres fram på denne og straks etter den emnetilførende anordning 13 at-skilles gjenstandene som føres fram av transportøren 11 i pakningsgrupper i linje The upper parts or lengths of the application chains 14 lie above the conveyor 11 at such a height that they practically lie at a height with the tops of the objects that are brought forward on it and immediately after the workpiece supplying device 13 the objects that are brought forward by the conveyor are separated 11 in packing groups in line

med emnene W på pålegningskjedene 14 with the blanks W on the application chains 14

ved hjelp av skilleskinner 15 som bæres av og strekker seg mellom atskilte kjeder 16 (sammenlign fig. 1 og 2 med fig. 3) ved by means of dividing rails 15 which are carried by and extend between separated chains 16 (compare fig. 1 and 2 with fig. 3) by

hver side av transportøren 11 og som be-virker atskillelsen av pakningsgruppene og vedlikeholder de atskilte pakningsgrupper mens de vandrer kontinuerlig med drivhastigheten for bærekj edene 16. each side of the conveyor 11 and which causes the separation of the packing groups and maintains the separated packing groups while they travel continuously at the drive speed of the carrier chains 16.

De atskilte pakningsgrupper føres deretter fra transportøren 11 over på to mat-ningsbelter 17 anordnet for å understøtte de respektive gjenstandsrekker i pakningsgruppene, og pakningsgruppene og de i linje med samme anordnede omslagsemner W føres under en overliggende belastnings-konstruksjon 17' for å vedlikeholde den innbyrdes stilling av gruppen og emnene når skilleskinnene 15 trekkes tilbake for å The separated packing groups are then passed from the conveyor 11 onto two feeding belts 17 arranged to support the respective rows of items in the packing groups, and the packing groups and the same arranged wrapping blanks W are passed under an overlying load structure 17' to maintain the mutual position of the group and the subjects when the dividing rails 15 are retracted to

tilveiebringe klaring for nedbretning av provide clearance for degradation of

omslagsemnet W over sidene av pakningsgruppene ved den første brettestasjon 18. the wrapping blank W over the sides of the packing groups at the first folding station 18.

En annen rekke av skilleskinner 19 anordnet på kjeder 20 føres deretter tversover inn mellom pakningsgruppene, méd endepartiene av omslagsemnene W nu for-løpende nedad under matningsbeltene 17 for å overlappe under pakningsgruppene. For å utføre denne overlapping føres pakningsgruppene fram ved skilleskinnene 19 fra matningsbeltene 17 gjennom en annen brettestasjon ved 21, og føres deretter til-slutt forbi en låsestasjon 22 hvor de over-lappede partier av omslagsemnene W for-bindes i overensstemmelse med foreliggende oppfinnelse. Another row of dividing rails 19 arranged on chains 20 is then fed transversely between the packing groups, with the end portions of the wrapping blanks W now extending downwards under the feeding belts 17 to overlap under the packing groups. In order to carry out this overlapping, the packing groups are fed forward at the dividing rails 19 from the feeding belts 17 through another folding station at 21, and are then finally fed past a locking station 22 where the overlapped parts of the wrapping blanks W are connected in accordance with the present invention.

Arrangementet av låseanordningen 22 er vist i detalj i fig. 3, 4 og 5 hvori den er vist omfattende et tverrhode 23, som bærer oppadrettede fingerelementer 24 og er driv-forbundet med kammer 25 og 26 for å bli meddelt en syklisk bevegelse ved hvilken det bringes til å. følge den kontinuerlige vandring av den i omslaget innelukkede pakningsgruppe forbi låsestasjonen 22 mens det stiger for å låse omslagsemnene W sikkert omkring pakningsgruppen ved hjelp av fingerelementene 24. The arrangement of the locking device 22 is shown in detail in fig. 3, 4 and 5 in which it is shown comprising a crosshead 23, which carries upwardly directed finger members 24 and is drive-connected with cams 25 and 26 to be imparted a cyclic movement by which it is caused to follow the continuous travel of the the wrap enclosed packing group past the locking station 22 as it rises to lock the wrapping blanks W securely around the packing group by means of the finger elements 24.

Den følgende komponent av denne sykliske bevegelse utføres ved kammen 25 og en glidende kamfølger 27 som er forbundet med den nedre ende av en vekt-arm 28 som er dreibar ved 29 og strekker seg oppad til en forbindelsesstangkonstruk-sjon 30 som fører til tverrhodet 23 (sammenlign fig. 3 og 5) for å bevirke horisontal fram- og tilbakebevegelse av dette på en sleidedel 31 anordnet ved innstillings-stenger 32 som er glidbart montert for ver-tikal bevegelse. Den stigende komponent av den sykliske bevegelse bevirkes av en forbindelsesstang 33 som strekker seg nedad fra sleidedelen 31 for å leddforbindes ved 34 til en løftearm 35 som rir på kammen 26. The following component of this cyclic movement is carried out by the cam 25 and a sliding cam follower 27 which is connected to the lower end of a weight arm 28 which is pivotable at 29 and extends upwards to a connecting rod structure 30 which leads to the crosshead 23 ( compare Fig. 3 and 5) to effect horizontal forward and backward movement thereof on a slide part 31 arranged by adjusting rods 32 which are slidably mounted for vertical movement. The ascending component of the cyclic movement is effected by a connecting rod 33 which extends downwards from the slide part 31 to be articulated at 34 to a lifting arm 35 which rides on the cam 26.

Begge drivkammene 25 og 26 er montert på en felles aksel 36 som gjennom en kjedehjulsforbindelse 37 drives fra en aksel 38, som er en av de aksler om hvilke bære-kjedene 20 for det annet sett av skilleskinner 19 er ført for å skaffe tidsinnstilt drift av tverrhodet 23 i forhold til van-dringshastigheten av skilleskinnene 19 som mater de med omslag utstyrte pakningsgrupper forbi låsestasjonen 22, som foran angitt. Both drive cams 25 and 26 are mounted on a common shaft 36 which, through a sprocket connection 37, is driven from a shaft 38, which is one of the shafts about which the carrier chains 20 for the second set of dividing rails 19 are guided to provide timed operation of the crosshead 23 in relation to the travel speed of the separating rails 19 which feed the packing groups equipped with covers past the locking station 22, as indicated above.

Akslen 38 som driver kjedene med skilleskinnene 19 har også en drivende kje-deforbindélse 39 med en aksel 40 på hvilken to kjeder 41 fører forbi tverrhodet 23 fra føringshjul ved 42. Disse kjeder 41 har deres øvre partier anordnet i linje med hver side og umiddelbart under bunnen av en med omslag utstyrt pakningsgruppe når den mates forbi låsestasjonen 22 (fig. 5) og hver kjede 41 bærer atskilte tappe-elementer 43 som stikker sideveis ut fra samme henimot den annen kjede i paret og danner glidestyringer hvorpå knastdeler 44 er montert sideveis forskyvbart for å stramme hvert pakningsomslag W for befestigelse om en pakningsgruppe ved låsestasjon 22, som nedenfor forklart. Hver knastdel 44 bærer ved undersiden en kam-rull 45 til å ligge an mot en kambane 46 ved hvilken dens sideforskyvning for stramning av omslagsemnet W utføres. The shaft 38 which drives the chains with the dividing rails 19 also has a driving chain connection 39 with a shaft 40 on which two chains 41 lead past the crosshead 23 from guide wheels at 42. These chains 41 have their upper parts arranged in line with each side and immediately below the bottom of a cover-equipped packing group when it is fed past the locking station 22 (Fig. 5) and each chain 41 carries separate pin elements 43 which protrude laterally from the same towards the other chain in the pair and form sliding guides on which cam parts 44 are mounted laterally displaceably to tighten each gasket wrap W for fastening about a gasket group at locking station 22, as explained below. Each cam part 44 carries at its underside a cam roll 45 to rest against a cam path 46 by which its lateral displacement for tightening the wrapping material W is carried out.

Et eksempel på et omslagsemne W som kan festes ved en låsestasjon 22 anordnet i overensstemmelse med foreliggende oppfinnelse er vist i fig. 6 og omfatter en toppvegg 47, to sidevegger 48 brettbart forbundet med motstående kanter av toppveggen 47, og to bunnvegghalvdeler eller fliker 49 og 50 som er brettbart forbundet med de respektive underkanter av sideveggene 48 og dimensjonert til å overlappe hverandre ved deres frie kantpartier for å danne en rektangulær firesidet pakning med helt åpne ender. An example of a cover blank W which can be fixed at a locking station 22 arranged in accordance with the present invention is shown in fig. 6 and comprises a top wall 47, two side walls 48 foldably connected to opposite edges of the top wall 47, and two bottom wall halves or tabs 49 and 50 which are foldably connected to the respective lower edges of the side walls 48 and dimensioned to overlap each other at their free edge portions to form a rectangular four-sided gasket with completely open ends.

Toppveggen 47, sideveggene 48 og bunveggspartiene 49 og 50 omfatter partier av et enkelt emne med i hovedsaken rektangulær form og tverrgående sveknings-linjer for å anordne disse partier i en The top wall 47, the side walls 48 and the bottom wall parts 49 and 50 comprise parts of a single blank with an essentially rectangular shape and transverse weakening lines to arrange these parts in a

brettbart forbundet rekke, idet alle partier på tvers av emnet W har lik lengde som foldable connected row, in that all parts across the workpiece W have the same length as

praktisk talt er lik lengden av pakningsgruppen som skal pakkes inn i samme. Bunnveggens halvdeler eller fliker 49 og 50 danner når de overlapper hverandre en bunnvegg med en bredde lik bredden av toppveggen 47 og praktisk talt lik to gan-ger diameteren av gjenstandene som skal pakkes inn slik at omslagsemnet W er anordnet til å omslutte en pakningsgruppe dannet av to rekker av gjenstander. is practically equal to the length of the packing group to be packed in the same. The bottom wall halves or flaps 49 and 50 when they overlap each other form a bottom wall with a width equal to the width of the top wall 47 and practically equal to twice the diameter of the objects to be wrapped so that the wrapping blank W is arranged to enclose a packing group formed by two rows of objects.

Omslagsemnet W er, anordnet på ovennevnte måte, avpasset til å anbringes på en pakningsgruppe av gjenstander og festes på denne under en pakkeoperasjon ved et arrangement av hunndelene 49 og 50 hvorved de griper låsende inn i hverandre for å feste omslagsemnet W i stilling uten, hvis så ønskes, at der trenges noen påføring av klebestoff på den overlappende bunnvegg. Fbr dette øyemed har den indre bunnveggsdel 49 i samme utskårne holdetunger 51 og den annen bunndel 50 tilpas-sede låsetunger 52. The wrapping blank W, arranged in the above manner, is adapted to be placed on a packing group of articles and fixed thereon during a packing operation by an arrangement of the female parts 49 and 50 whereby they engage lockingly with each other to secure the wrapping blank W in position without, if then it is desired that some application of adhesive is needed on the overlapping bottom wall. For this purpose, the inner bottom wall part 49 has in the same cut-out retaining tongues 51 and the other bottom part 50 adapted locking tongues 52.

Både holdetungene 51 og låsetungene 52 er anordnet til å være hengslet eller Both the holding tongues 51 and the locking tongues 52 are arranged to be hinged or

festet til bunnveggens halvdeler henholds-vis 49 og 50 ved den lengst fra kanten av samme vendende ende, slik at der brettes i motsatt forhold og den frie lengde av holdetungene 51 er gjort litt større enn lengden av låsetungene 52 slik at disse siste kan være ført innad gjennom det overlappende kantparti av den indre bunnhalvdel 49 ved de respektive holdetunger 51 i samme. Avstanden mellom tungene 51 og 52 er slik at de blir plasert i det frie rom mellom tilgrensende sylindriske gjenstander i en pakningsgruppe og derved utnytte dette mellomrom for å skaffe klaring for å bringe tungene i låseinngrep. attached to the halves of the bottom wall respectively 49 and 50 at the furthest from the edge of the same facing end, so that it folds in the opposite ratio and the free length of the retaining tongues 51 is made slightly greater than the length of the locking tongues 52 so that the latter can be guided inwards through the overlapping edge part of the inner bottom half 49 at the respective retaining tongues 51 in the same. The distance between the tongues 51 and 52 is such that they are placed in the free space between adjacent cylindrical objects in a packing group and thereby utilize this space to provide clearance to bring the tongues into locking engagement.

Låsetungene 52 er videre formet på en spesiell måte med i bredden utvidede endepartier som danner skuldre, som ved 53, som er avpasset til å ligge over den indre bunnvegghalvdel 49 ved hver side av holdetungene 51 og derved tilveiebringe låseinngrep mellom bunnvegghalvdelene 49 og 50. Under innføringen av de med skuldre utstyrte låsetunger 52 i dette låseinngrep forskyves holdetungene 51 oppad ved de ytre ender av låsetungene 52 for å presse de innførte låsetunger 52 i stilling. The locking tongues 52 are further shaped in a special way with widened end portions which form shoulders, as at 53, which are adapted to lie above the inner bottom wall half part 49 on each side of the retaining tongues 51 and thereby provide locking engagement between the bottom wall halves 49 and 50. Under the introduction of the locking tongues 52 equipped with shoulders in this locking engagement, the holding tongues 51 are displaced upwards at the outer ends of the locking tongues 52 to press the introduced locking tongues 52 into position.

Bunnvegghalvdelene 49 og 50 er videre hver utstyrt med åpninger 54 og 55 i noen avstand fra sine ender og fra de tilliggende sidevegger 48 for å bli plasert innenfor omkretsen av en gjenstand pakket i omslaget W for å skaffe klaring ved disse åpninger 54 og 55 for å gripe bunnvegghalvdelene 49 og 50 og holde dem i riktig, overlappende stilling mens låsetungene 52 bringes i låseinngrep som forklart nærmere i det følgende. The bottom wall halves 49 and 50 are further each provided with openings 54 and 55 at some distance from their ends and from the adjacent side walls 48 to be placed within the circumference of an object packed in the wrapper W to provide clearance at these openings 54 and 55 to grasp the bottom wall halves 49 and 50 and hold them in the correct, overlapping position while the locking tongues 52 are brought into locking engagement as explained in more detail below.
