Abstract

In a machine for making paper booklets from a multiplicity of paper strips on bobbins that are converged into a continuously advancing strand a reciprocating cutting station (25) defined by leading and trailing plates (27, 28) performs the operations of firstly clamping the strand while the station (25) moves with the strand and secondly of cutting off booklet lengths of paper by means of a knife (156). Cut booklets are ejected into a discharge chute (32) by ejection means (200) including an ejector bar (211) terminating a thrust plate (214). According to the invention the ejection means (200) is separated from the cutting station (25) and is fixedly located opposite to the chute (32). Connection between the cutting station (25) and the ejection means (200) is established by a common rotating hexagonal shaft (76) which is operably connected to clamping and cutting mechanisms of the station (25) and which carries a pair of cams (207, 208) that actuate the ejector (211) through a parallelogram linkage. By this means the motion of the ejector (211) can be gradual rather than abrupt, the machine is easier to set up, and the ejector thrust plate (214) can span substantially the full width of chute (32) so that the likelihood of cut booklets becoming misplaced is reduced.

Description

Bord med hev- og senkbar ramme som bærer eh bordplate. Table with a raise and lower frame that carries a table top.

Oppfinnelsen angår et bord av den i patentkravets innledning angitte art. The invention relates to a table of the type specified in the introduction of the patent claim.

En stor ulempe ved tidligere kjente bord av denne art består i at hevningen og senkningen av bordplaten skjer ved hjelp av uhensikts-messige organer, som eksempelvis krever at ved platens hevning forst dens ene og deretter dens andre ende loftea opp for hånd, hvorved spesielle stCtteorganer trer i funksjon for å holde bordplaten i opploftet stilling. A major disadvantage of previously known tables of this type is that the raising and lowering of the table top takes place with the help of inappropriate devices, which for example require that when the plate is raised, first one end and then the other end are lifted up by hand, whereby special support devices comes into play to keep the table top in the raised position.

Formålet med foreliggende oppfinnelse er forst og fremst i oven-nevnte henseende å forbedre og videreutvikle slike bord. The purpose of the present invention is primarily in the above-mentioned respect to improve and further develop such tables.

Dette er ifttlge oppfinnelsen oppnådd ved å utforme bordet i henhold til de i patentkravets karakteriserende del angitte trekk. Ved et sådant bord er styre- og lofte-senke-funksjonene forenet i samme organ, hvilket resulterer i en enkel utførelse og funksjons-måte samt stor funksjonssikkerhet og -noyaktighet av bordets bevegelige deler. According to the invention, this is achieved by designing the table according to the features specified in the characterizing part of the patent claim. With such a table, the steering and loft-lowering functions are united in the same body, which results in a simple design and way of functioning as well as great functional reliability and accuracy of the table's moving parts.

Ytterligere fordeler med oppfinnelsen fremgår av etterfølgende detaljbeskrivelse under henvisning til tegningene, der fig. 1 viser en utforelsesform for et bord iftilge oppfinnelsen for i sideretning uttrekkbare klaffer og med kanten av den opploftede plate antydet ved strekete linjer i grunnriss, mens fig. 2 viser samme bord i lengdesnitt. Further advantages of the invention appear from the following detailed description with reference to the drawings, where fig. 1 shows an embodiment of a table according to the invention for laterally extendable flaps and with the edge of the raised plate indicated by dashed lines in the ground plan, while fig. 2 shows the same table in longitudinal section.

Ifolge den på tegningene viste utforelsesformen innbefatter bordet sidesarger 1 og gavlsarger 2, som på kjent måte bæres av ben 3. According to the embodiment shown in the drawings, the table includes side frames 1 and gable frames 2, which are carried by legs 3 in a known manner.

Få sidesargenes 1 innside er anbragt fire parvis anordnede stdtter 4» hvis nedre ende er forskyvbar i et tilsvarende antall spor 5 som er innfelt i sidesargene 1 i nærheten av deres ender. Sporenes lengde avgjores av stottenes hoyde. For svingning av stottene er det for hver stotte anordnet et stag 6, som med sin ene ende er svingbart lagret på innsiden av sides&rgene 1, mens den andre enden er leddforbundet med stottenes sentrale del. Ettersom stottene forskyves samtidig, er deres nedre ender parvis forbundet med en aksel 7, som forloper parallelt med gavlsargene 2, og hvis ender er innfort i de tidligere nevnte spor 5. Den ovre enden av stottene sr fast forbundet med en overliggende bæreaksel 8, som strekker seg i samme retning som forstnevnte aksel. Bære-akalene 8, som er to i antall, er dreibart lagret i en ramme 9» 10, som er bestemt til å feides ned mellom sargene. On the inside of the side skirts 1 are placed four pairs of supports 4" whose lower end is displaceable in a corresponding number of slots 5 which are embedded in the side skirts 1 near their ends. The length of the tracks is determined by the height of the supports. For swinging the supports, a strut 6 is arranged for each support, one end of which is pivotally mounted on the inside of the side supports 1, while the other end is articulated with the central part of the supports. As the supports are displaced at the same time, their lower ends are connected in pairs to an axle 7, which runs parallel to the gable edges 2, and whose ends are inserted into the previously mentioned grooves 5. The upper end of the supports is firmly connected to an overlying support shaft 8, which extends in the same direction as the aforementioned axle. The bearing akals 8, which are two in number, are rotatably stored in a frame 9" 10, which is intended to be swept down between the edges.

Et sådant bord egner seg utmerket for opptagelse av uttrekkbare klaffer (uttrekksklaffer). For dette formål har de tverrgående deler 10 av rammen skrånende spor på sidene for samvirkning med bærelister 12 med en fjær 13* Bordplaten 15 fastholdes ved hjelp av bolter. ;Akslene 7> som er innrettet til å forskyves radialt er hver for dette formål forsynt med en stang 18, hvis andre ende er leddforbundet med endene av en toarmet, omkring en vertikal aksel 26 svingbar vektstang 19* Den ene av vektstangens armer er forlenget i form av et håndtak 20 for vektstangens svingning. For sperring av bordet i forskjellige stillinger er det anordnet et sperre-organ 21 utfort i bueform og fastgjort på undersiden av en plate 22, som er innsatt mellom sidesargene 1. For å forhindre at bordet ved dets nedfelding stoter stumpt mot platen 22, er det på dens overside anbragt to bladfjærer 23. For utjevning av tyngden fra den hev- og senkbare delen av bordet er det mellom gavlsargene 2 og akslene 7 innsatt to fjærer 24, som medvirker ved rammens loftning. Such a table is excellently suited for recording retractable flaps (extractable flaps). For this purpose, the transverse parts 10 of the frame have sloping grooves on the sides for interaction with support strips 12 with a spring 13* The table top 15 is held by means of bolts. ;The shafts 7> which are arranged to be displaced radially are each provided for this purpose with a rod 18, the other end of which is articulated with the ends of a two-armed, around a vertical shaft 26 pivotable barbell 19* One of the barbell's arms is extended in form of a handle 20 for swinging the barbell. For locking the table in different positions, a locking device 21 is arranged in an arched shape and fixed to the underside of a plate 22, which is inserted between the side edges 1. To prevent the table from colliding bluntly against the plate 22 when it is folded down, it is two leaf springs 23 are placed on its upper side. To equalize the weight from the raising and lowering part of the table, two springs 24 are inserted between the end frames 2 and the shafts 7, which contribute to the lofting of the frame.

Ved loftning av bordplaten 15 fra nedfeldt stilling trykkes den fjærbelastede vektstangen ved hjelp av håndtaket nedad og losgjores dermed fra sitt inngrep med den ene ende av sperreorganet 21 og svinges til dets motsatte ende. Svingningen lettes av fjærene 24. Herunder forskyves akslene 7 mot bordets gavlsarger 2 og samtidig svinges stottene 4 oppover, hvorved rammen 9,10 folger med. Når bordet har nådd sin ovre stilling, fastlåses vektstangen ved den motsatte enden av sperreorganet. Etter hevningen kan evt. uttrekksklaffer trekkes ut. For styring av uttrekksklaffene såvel i inn-skjovet som uttrukket stilling er det i sidesargene 1 utformet utsparinger 25, i hvilke bærelistene 12 glir. When lifting the table top 15 from its folded position, the spring-loaded barbell is pressed downwards by means of the handle and is thus released from its engagement with one end of the locking member 21 and swung to its opposite end. The oscillation is facilitated by the springs 24. Below this, the shafts 7 are displaced towards the table's gables 2 and at the same time the supports 4 are swung upwards, whereby the frame 9,10 follows along. When the table has reached its upper position, the barbell is locked at the opposite end of the locking member. After the lift, any pull-out flaps can be pulled out. For controlling the pull-out flaps both in the pushed-in and extended positions, recesses 25 are formed in the side frames 1, in which the support strips 12 slide.
