Abstract

FREMGANGSMÅTE TIL BEHANDLING AV ET IKKE-VEVET STOFF.PROCEDURE FOR TREATMENT OF A NON-WOVEN FABRIC.

Description

Maskin for stabling av bunter av aviser og liknende gjenstander. Machine for stacking bundles of newspapers and similar objects.

Foreliggende oppfinnelse angår en The present invention relates to a

maskin for stabling av bunter av aviser og liknende gjenstander, omfattende en avlegger beregnet på på to fellbare luker å motta en rekke bunter og å avlegge samme på en trinnvis fremover og bakover bevegelig lastepall, på hvilken buntrekkene avlegges ved siden av og ovenpå hverandre for dannelse av en stabel med et antall buntsjikt. Når stabelen skal inneholde et flertall sjikt er det vanlig f. eks. på hvert fjerde sjikt å anbringe en skive av f. eks. board for derved å stabilisere stabelen. machine for stacking bundles of newspapers and similar articles, comprising a depositor designed to receive, on two collapsible hatches, a series of bundles and to deposit the same on a step forward and backward movable loading pallet, on which the rows of bundles are deposited side by side and on top of each other to form of a stack with a number of bundle layers. When the stack is to contain a majority layer, it is common, e.g. on every fourth layer to place a disk of e.g. board to thereby stabilize the stack.

Denne innlegging av stabiliseringsskiver er hittil blitt utført for hånden. I den hensikt å unngå dette manuelle arbeid har oppfinnelsen som formål å skaffe en ileggings-anordning som er innkoplebar for å hente en stabiliseringsskive fra et magasin og anbringe den på et ferdigdannet buntsjikt innen dannelsen av neste sjikt påbegyn-nes. For dette formål kjennetegnes maskinen ifølge oppfinnelsen vesentlig ved at det ovenpå avleggeren er anbragt et magasin for skiver beregnet på å bli anbragt på buntsjiktene for stabilisering av den blivende stabel, at den underste skive i magasinet ved hjelp av en fremmatingsanordning er utskytbart til en stilling ved siden av magasinet, der en løftbar og senkbar holder er anordnet til å motta skiven, og at holderen er drivbar fra en øvre endestilling der den mottar den utskutte skive til en nedre endestilling der den er innrettet til å avlegge skiven på det øverste buntsjikt, idet fremmatingsanordningen og holderens drivanordning er således samord-net med stablingen at en skive avlegges på f. eks. hvert fjerde buntsjikt. Herved skaffes en maksimal innlegging av stabiliseringsskiver på ønskede høyder av stabelen. Ved at magasinet er anbragt på avleggeren, som løftes alt ettersom stabelen øker i høyde, krever skivemagasinet ikke noe ekstra rom ved siden av maskinen. Hensiktsmessig består holderen av et par parallelle, horisontale bærearmer som strekker seg vinkelrett på magasinets ene side og er anordnet til å bære den utskutte skive ved begge dennes kanter. This insertion of stabilizing discs has hitherto been carried out by hand. In order to avoid this manual work, the purpose of the invention is to provide an insertion device that can be switched on to retrieve a stabilization disc from a magazine and place it on a ready-made bundle layer before the formation of the next layer begins. For this purpose, the machine according to the invention is significantly characterized by the fact that a magazine for discs intended to be placed on the bottom layers for stabilizing the remaining stack is placed on top of the feeder, that the bottom disc in the magazine with the aid of a feed device can be ejected to a position at side of the magazine, where a liftable and lowerable holder is arranged to receive the disc, and that the holder is operable from an upper end position where it receives the ejected disc to a lower end position where it is arranged to deposit the disc on the uppermost bundle layer, The feed device and the holder's drive device are thus coordinated with the stacking that a disc is placed on e.g. every fourth bottom layer. This provides a maximum insertion of stabilization discs at desired heights of the stack. As the magazine is placed on the branch, which is lifted as the stack increases in height, the disc magazine does not require any extra space next to the machine. Conveniently, the holder consists of a pair of parallel, horizontal support arms which extend perpendicular to one side of the magazine and are arranged to support the cut-out disk at both its edges.

Disse og øvrige for oppfinnelsen kjen-netegnende trekk fremgår nærmere av følgende beskrivelse av en på tegningene vist utførelsesform for oppfinnelsen. Fig. 1 er et sideriss av en maskin for stabling av avisbunter og forsynt med en avlegger som bærer et skivemagasin med løftbar og senkbar holder ifølge oppfinnelsen. Fig. 2 er et skjematisk perspektivriss av en ved magasinets bunn anbragt anordning for utskytning av den underste skive på den med strekpunkterte linjer antydete holders horisontale bærearmer. Fig. 3 er et skjematisk perspektivriss av holderens ene side med dens deler tatt fra hverandre for å lette forståelsen av drivsystemet. Fig. 4 er et delvis brutt riss av avleggeren, magasinet og holder med drivanordning, og These and other features characteristic of the invention appear in more detail from the following description of an embodiment of the invention shown in the drawings. Fig. 1 is a side view of a machine for stacking newspaper bundles and provided with a branch carrying a disc magazine with liftable and lowerable holder according to the invention. Fig. 2 is a schematic perspective view of a device placed at the bottom of the magazine for launching the lower disk onto the holder's horizontal support arms indicated by dotted lines. Fig. 3 is a schematic perspective view of one side of the holder with its parts taken apart to facilitate understanding of the drive system. Fig. 4 is a partially broken view of the branch, magazine and holder with drive device, and

fig. 5 er et riss sett ovenfra av frem- fig. 5 is a top view of the forward

matingsanordningen og holderen i dens øvre endestilling. the feeding device and the holder in its upper end position.

I fig. 1 vises en lastepall 10 som er trinnvis bevegelig frem og tilbake under en løftbar og senkbar avlegger 11 forsynt med fellbare luker 12, 13, som vises med strekpunkterte linjer i nedfelt stilling. På disse luker innføres en rekke avisbunter, som avlegges ved siden av og ovenpå hverandre for dannelse av et antall buntsjikt 14, 15, 16, 17. På det fjerde sjikt 17 er anbrakt en stabiliseringsskive 18 av f. eks. board, på hvilken ytterligere et antall buntsjikt er beregnet å bli stablet innen ytterligere en skive anbringes som stabili-serende mellomlegg. In fig. 1 shows a loading pallet 10 which is stepwise movable back and forth under a liftable and lowerable branch 11 provided with collapsible hatches 12, 13, which are shown with dotted lines in the lowered position. A number of newspaper bundles are introduced on these hatches, which are placed next to and on top of each other to form a number of bundle layers 14, 15, 16, 17. On the fourth layer 17 is placed a stabilizing disc 18 of e.g. board, on which a further number of bottom layers is intended to be stacked within a further disc is placed as a stabilizing spacer.

Ovenpå avleggeren 11 er det anbragt et magasin 19 for et antall stabiliseringsskiver, av hvilke den underste ved hjelp av den i fig. 2 viste fremmatingsanordning er utskytbar på den løftbare og senkbare holder 20, som er slik drevet og styrt at den avlegger skiven på stabelen, som antydet med skiven 18. On top of the branch 11, a magazine 19 is placed for a number of stabilization discs, of which the lower one by means of the one in fig. 2 shown feeding device is ejectable on the liftable and lowerable holder 20, which is driven and controlled in such a way that it deposits the disc on the stack, as indicated by the disc 18.

I den i fig. 1 viste stilling, eller ved hvilken som helst annen høyde på stabelen, innkoples en drivmotor 21 for drift av tre parallelle, tversgående aksler 22, 23, 24, forsynt med kjedehjul for et par ytre transportkjeder 25, 26 mellom akslene 22, 24, og et par kortere indre transportkjeder 27, 28 mellom akslene 24, 23. In the one in fig. 1 shown position, or at any other height of the stack, a drive motor 21 is engaged for operation of three parallel, transverse shafts 22, 23, 24, provided with sprockets for a pair of outer transport chains 25, 26 between the shafts 22, 24, and a pair of shorter inner transport chains 27, 28 between the shafts 24, 23.

Kjedene 25, 26 er forsynt med tre par motstående medbringere 29, 30, som griper den underste skive ved dens bakkant og begynner utskytningen av denne skive 31, antydet med stiplede linjer i fig. 2. Når medbringerorganene 29, 30 har skutt frem den nederste skive et lite stykke har kjedene 27, 28 ført et par motstående støtte-ruller 32, 33 opp til anlegg mot og oppløf-ting av den nest nederste skive og ovenpåliggende skiver, idet den underste skive passerer ut gjennom en spalte 36 (fig. 4) ved magasinets fremre endevegg 37 mens øvrige skiver stoppes av denne endevegg. Ved oppløfting av de igjenliggende skiver i magasinet ved hjelp av støtterullene 32, 33, lettes utmatingen av den underste skive slik at utmatingen kan skje hurtig med forholdsvis liten kraft. Som det fremgår av fig. 2 finnes de to par medbringerorga-ner 29, 30 og tre par støtteruller 32, 33. The chains 25, 26 are provided with three pairs of opposite carriers 29, 30, which grip the lower disc at its rear edge and begin the ejection of this disc 31, indicated by dashed lines in fig. 2. When the drive members 29, 30 have pushed the lowest disc forward a short distance, the chains 27, 28 have led a pair of opposite support rollers 32, 33 up to abut against and lift the second lowest disc and overlying discs, as the the bottom disc passes out through a slot 36 (fig. 4) at the magazine's front end wall 37, while other discs are stopped by this end wall. By lifting the discs remaining in the magazine with the aid of the support rollers 32, 33, the ejection of the lower disc is facilitated so that the ejection can take place quickly with relatively little force. As can be seen from fig. 2 there are two pairs of drive members 29, 30 and three pairs of support rollers 32, 33.

Som det fremgår av figurene består den løftbare og senkbare holder 20 av to parallelle bærearmer 38, 39, som ved hjelp av en drivanordning er forflyttbare fra den med helt opptrukkne linjer viste øvre endestilling i fig. 4 til den med stiplede linjer i samme figur viste nedre endestilling, der den på bærearmene utskutte skive avlegges på det underliggende buntsjikt, f. eks. sjiktet 17 i fig. 1. As can be seen from the figures, the liftable and lowerable holder 20 consists of two parallel support arms 38, 39, which can be moved with the help of a drive device from the upper end position shown in solid lines in fig. 4 to the lower end position shown with dashed lines in the same figure, where the disc cut out on the support arms is placed on the underlying bundle layer, e.g. layer 17 in fig. 1.

I fig. 3 vises bare den venstre side av holderen med armen 39 og dens drivsystem ettersom den høyre arm 38 er utført og styrt på hovedsakelig samme måte. In fig. 3 only the left side of the holder is shown with the arm 39 and its drive system as the right arm 38 is designed and controlled in substantially the same way.

Armen 38 henholdsvis 39 består av en horisontal bæreskinne 40 henholdsvis 41, som er svingbart forbundet med en side-støtteskinne 42 henholdsvis 43, således at skinnene 42, 43 kan innta en horisontal stilling for bæring av en skive, eller felles ned til en vertikal stilling for avlegging av skiven. Ved hjelp av en fjæranordning 44 The arm 38 and 39 respectively consist of a horizontal support rail 40 and 41 respectively, which is pivotably connected to a side support rail 42 and 43 respectively, so that the rails 42, 43 can assume a horizontal position for carrying a disc, or fold down to a vertical position for depositing the disc. By means of a spring device 44

(fig. 3) holdes bæreskinnen i sin horisontale stilling for bæring av en skive. Ved et bestemt trykk på skiven ovenifra felles dog bæreskinnene 40, 41 ned, slik at skiven faller ned. Dette utnyttes ved at armene 38, 39 like før sin nedre endestilling bringes til å utføre en oppadgående bevegelse, slik at skiven trykkes opp mot et fast anslag 45 (fig. 4) og derved feller ned bæreskinnene 40, 41 for avlegging av skiven. (fig. 3) the support rail is held in its horizontal position for carrying a disc. However, when a specific pressure is applied to the disc from above, the support rails 40, 41 fall down, so that the disc falls down. This is utilized by the arms 38, 39 just before their lower end position being brought to perform an upward movement, so that the disc is pressed up against a fixed stop 45 (fig. 4) and thereby the support rails 40, 41 fall down for depositing the disc.

I det viste eksempel bæres og styres bærearmene av et lenksystem, som beskrives under henvisning til fig. 3, 4 og 5. For enkelhets skyld beskrives bare den venstre side av systemet, slik den fremgår av fig. In the example shown, the support arms are carried and controlled by a link system, which is described with reference to fig. 3, 4 and 5. For the sake of simplicity, only the left side of the system is described, as it appears from fig.

3 og 4. 3 and 4.

Lenksystemets venstre side består av en fremad rettet lenkarm 46 og en nedadrettet lenkarm 47. Disse lenkarmer er svingbart lagret på en tversgående aksel 48. Den f remadrettede lenkarm 46 har dess-uten en nedadrettet del 49, ved hvis nedre ende er roterbart lagret en styretrinse 50, som følger en fast kambane 51 i fig. 3 eller 52 i fig. 4. Denne kam er festet på en kon-soll 53 på maskinens stativ. The left side of the link system consists of a forward-directed link arm 46 and a downward-directed link arm 47. These link arms are pivotally mounted on a transverse shaft 48. The forward-directed link arm 46 also has a downward-directed part 49, at the lower end of which a guide pulley is rotatably mounted 50, which follows a fixed cam track 51 in fig. 3 or 52 in fig. 4. This comb is attached to a console 53 on the machine's stand.

Ved den nedadrettede lenkarms 47 nedre ende er festet en tversgående drivaksel 54, som er dreibart lagret i konsollen 53. Denne aksel er forsynt med et kjedehjul At the lower end of the downward-directed link arm 47, a transverse drive shaft 54 is attached, which is rotatably stored in the console 53. This shaft is equipped with a sprocket

54a, som via en endeløs kjede 55, et kjedehjul 56, en aksel 57 og ytterligere et kjedehjul drives ved hjelp av en kjede 59, som i sin tur drives frem eller tilbake ved hjelp av en ikke vist elektrisk motor eller et frem- og tilbakegående trykkluftstempel. 54a, which via an endless chain 55, a sprocket 56, an axle 57 and a further sprocket is driven by means of a chain 59, which in turn is driven forwards or backwards by means of an electric motor not shown or a reciprocating compressed air piston.

Drift av kjeden 59 i den med piler angitte retning resulterer i bevegelser i lenksystemet som antydet med piler. Lenkarmen 47 og dens aksel 48 svinges fremover og nedover til den med stiplede linjer antydete undre endestilling i fig. 4, idet lenkarmen 46 følger med i denne bevegelse samtidig som rullen 50 følger kam-banen 51 for å tvinge armens 46 fremre ende ned så hurtig som mulig. Bærearmene 38, 39 holdes under denne nedovergående bevegelse i sin horisontale stilling ved hjelp av følgende anordning. Som vist i fig. 3 er armen 39 festet på en tversgående aksel 60 som er dreibart lagret i armens 46 fremre ende. På denne aksel er festet et kjedehjul 61, som via en endeløs kjede 62 er forbundet med et kjedehjul 63, roterbart lagret på akselen 48 og fast forbundet med et inntil liggende kjedehjul 63, som også er roterbart i forhold til akselen 48. Videre er en endeløs kjede 65 lagt over kjedehjulet 64 og et fast kjedehjul 66 anordnet konsentrisk med den dreibare drivaksel 54 og frittløpende i forhold til denne. Dette kjedehjul er fast forbundet med konsollen 53. Operation of the chain 59 in the direction indicated by arrows results in movements in the link system as indicated by arrows. The link arm 47 and its shaft 48 are swung forwards and downwards to the lower end position indicated by dashed lines in fig. 4, as the link arm 46 follows this movement at the same time as the roller 50 follows the cam path 51 to force the front end of the arm 46 down as quickly as possible. The support arms 38, 39 are held during this downward movement in their horizontal position by means of the following device. As shown in fig. 3, the arm 39 is attached to a transverse shaft 60 which is rotatably mounted at the front end of the arm 46. Attached to this shaft is a sprocket 61, which via an endless chain 62 is connected to a sprocket 63, rotatably mounted on the shaft 48 and fixedly connected to an adjacent sprocket 63, which is also rotatable in relation to the shaft 48. Furthermore, a endless chain 65 laid over the sprocket 64 and a fixed sprocket 66 arranged concentrically with the rotatable drive shaft 54 and free-running in relation to this. This sprocket is firmly connected to the console 53.

De ovenfor angitte kjedehjul 66, 64, 63 og 61 er like store. Når armen 47 svinges The above stated sprockets 66, 64, 63 and 61 are the same size. When the arm 47 is swung

fremover kommer således kjeden 65 til å avrulle på det faste kjedehjul 66 samtidig som hjulene 64, 63 dreies bakover og via kjeden 62 og hjulet 61 også dreier akselen 60 bakover i den med pil angitte dreieret-ningen, hvilket medfører at bærearmen 39 holdes horisontal under hele nedsving-ningen av bærearmene 39, 38 til deres undre endestillinger. forward, the chain 65 thus comes to unroll on the fixed sprocket 66 at the same time as the wheels 64, 63 are turned backwards and via the chain 62 and the wheel 61 the shaft 60 also turns backwards in the direction of rotation indicated by the arrow, which means that the support arm 39 is kept horizontal during the entire downward swing of the support arms 39, 38 to their lower end positions.

Så snart bærearmene har avlevert skiven, påvirkes en grensestillingsbryter for omstyring av lenkesystemets drift, således at bærearmene går tilbake til den øvre endestilling. As soon as the support arms have delivered the disk, a limit switch is actuated to redirect the link system's operation, so that the support arms return to the upper end position.
