Description

Uppfinnare: 0 Haberkorn Prioritet begard fran den 18 januari 1955 (Feirbundsrepubliken Tyskland) FOreliggande uppfinning avser en anordning for tryckning av nollor vid additionsoch raknemaskiner med typsegmentens installnings organ fj adrande avkannande, tryckningssvangningen av de oberoende av varandra mot en pappersvals svangbara typsegmenten. vid nonage av deras ins tallningsorgan sparrande och under installningsrorelsen av iastallningsorganen ur ingrepp med dessa sig befinnande overbryggningsorgan, av vilka vart och ett är anordnat att medbringa det pa hoger sida intilliggande Overbryggningsorganet. Inventor: 0 Haberkorn Priority requested from 18 January 1955 (Federal Republic of Germany) The present invention relates to a device for printing zeros in addition and shaving machines with the type segments' installation means for sensing, the pressure swing of the independently of each other pivotable type segments. during nonage of their installation means sparring and during the installation movement of the installation means out of engagement with these are present bridging means, each of which is arranged to carry the right-hand bridging means.

En med tryckhamrar och typstanger arbetande tryckanordning ãr tidigare land, vid vilken Overbryggningselementen lianas tillbaka under installningsorganens installningsrO: relse medelst en slang, som är fast vid sparrbygeln fi5r tryckhamrarna. Vid denna anordning frigives under sparrbygelns frigivningsr8relse forst overbryggningsorganen fOr avkanningsrOrelsen mot installningsorganen och sedan tryckhanararna for avtryckningen. Detta kraver en mycket n.oggrann samverkan mellan de ifragavarande delarna och forutsatter en fOrhallandevis 1A.'ngsam rorelse av sparrbygeln for att sakerstalla, att overbryggningsorganens avkanning av installningsorganen genomfOres fullstandigt, innan hamrarna friges medelst sparrbygeln. A pressure device operating with pressure hammers and type rods is a former land, in which the bridging elements are lined back during the installation movement of the installation means by means of a hose, which is fixed to the ratchet bracket for the pressure hammers. In this device, during the release movement of the ratchet bar, first the bridging means for the sensing movement towards the installation means and then the pressure cocks for the impression are released. This requires a very close co-operation between the parts in question and presupposes a relatively smooth movement of the ratchet bracket in order to ensure that the bridging means of the bridging means of the installation means are carried out completely before the hammers are released by means of the ratchet bar.

Anordningen enligt uppfinningen kannetecknas darigenom, aft en typsegmenten i deras installda vardelagen sparrande riktbygel am anordnad att i sitt typsegmenten frigivande lage Ulla tillbaka de fjaderpaverkade Overbryggningsorganen och att i sitt typsegmenten sparrande lage tillâta overbryggningsorganens avkanningsrorelse. The device according to the invention can thus be characterized by a type segments in their installed guardrail sparring guide bracket arranged to release the spring-actuated bridging means in their type segments and to allow the scanning movement of the bridging members in its type segments sparingly.

Genom denna algid astadkommes automatiskt att avkanningen av installningsorganen sker forst, sedan dessa organ bragts till fullstandig vila och att rorelsen av sparrbygeln for typsegmentens trycksvangning forskjutes till en tidpunkt, liar med sakerhet avkanningen av installningsorganen avslutats genom overbryggningsorganen. Detta har till f8ljd, att raknehastigheten kan okas och konstruktionen forenklas. This algorithm automatically ensures that the scanning of the installation means takes place only after these means have been brought to a complete rest and that the movement of the ratchet bar for the pressure segments of the type segments is postponed to a time when the scanning of the installation means is completed by the bridging means. As a result, the shaving speed can be increased and the construction simplified.

En anordning fOr tryckning av nollor vid raknemaskiner är tidigare kand, vid vilken rorelsen av overbryggningsorganen sker under inverkan av en med sparrbygeln f Or typstangerna forbunden stang, men vid denna tidigare kanda anordning är det dock icke fraga om en tillbakahallningsstang utan om en tryckstang, som pressar ut overbryggningsorganen ur deras typsegmenten sparrande lage At hOger fran det h8gsta laget av sum-man. Darvid medtages samtliga till hoger om det hogsta laget av summan sig befinnande overbryggningsorgan, vilkas installningsorgan sta pa noll. Under vissa omstandigheter maste darvid en enda 8verlappningsansats medtaga samtliga till Niger staende overbryggningsorgan, vilket latt leder till en overanstrangning av ifragavarande overlappningsansats och kan — till foljd av den sig adderande, oundvikliga dodgangen — leda till felavtryck. A device for printing zeros in razors is previously known, in which the movement of the bridging means takes place under the influence of a rod connected to the ratchet f Or type rods, but in this earlier known device it is not a retaining rod but a push rod, which pushes the bridging members out of their type segments sparring layer At right of the highest layer of sum-man. In this case, all bridging means located to the right of the highest layer of the sum are included, the installation means of which are zero. In certain circumstances, a single overlap approach must involve all bridging bodies standing to Niger, which has led to an overexertion of the overlap approach in question and can - as a result of the inevitable deadlock - lead to misprints.

Ytterligare kannetecken pa uppfinningen skola framga av den foljande beskrivningen med han-visning till den bifogade ritningen, som visar ett utforingsexempel pa uppfinningen. Fig. 1 ãr en. sidovy av tryckverket med nolltryckningsanordningen i riktbygelns vilolage, fig. 2 en motsvarande delvy med riktbygeln i sparrlage och fig. 3 en vy ovanifran av fig. 2. Further features of the invention will appear from the following description with reference to the accompanying drawing, which shows an embodiment of the invention. Fig. 1 is a. side view of the printing unit with the zero pressure device in the resting layer of the directional bar, Fig. 2 is a corresponding partial view with the directional bar in the spar position and Fig. 3 is a top view of Fig. 2.

De medelst fyrkantsstanger 1 (fig. 1) i langdriktningen rorligt anordnade installningsorgan 2 sta standigt i ingrepp med mellanhjul 3, vilka samverka med tandningar 4, 2— — som aro anordnade pa. med en pappersvals 5 samverkande typsegment 6. Typsegmenten 6 jamte tandningarna 4 aro medelst tappar 7 vridbart lagrade pa havstanger 8. Havstangerna 8 aro svangbart lagrade pa en gemensam stang 9 pa sa salt, aft dessa frau sitt i fig. 1 visade vilolage, vid vilket tandningarna 4 sta i ingrepp med mellanhjulen 3, kunna svangas At hOger till anslag av de installda typerna mot pappersvalsen 5. Trycksvangningen av havstangerna 8 astadkommes genom fjadrarna 11, efter att en gemensam pa en axel 12 fastsatt sparrbygel 13 utsvanges ur havstangernas 8 sparrspar 14. Aterforingen av havstangerna 8 till det visade vilolaget astadkommes gemensamt genom en aterforingsstang 15, som uppbares av havstangssegment 16, vilka medelst en stotstang 17 pa motsvarande satt och pa viss tid fOrflyttas av pa huvuddrivaxeln 18 belagna kurvskivor. The installation means 2 arranged by means of square rods 1 (Fig. 1) in the longitudinal direction are permanently in engagement with intermediate wheels 3, which co-operate with teeth 4, 2 - which are arranged on. cooperating type segments 6 with a paper roll 5. The type segments 6 together with the teeth 4 are rotatably mounted on sea rods by means of pins 7. The sea rods 8 are pivotally mounted on a common rod 9 on such salt, from these from their resting position shown in Fig. 1. the teeth 4 are engaged with the intermediate wheels 3, can be pivoted to the right to abut the installed types against the paper roll 5. The pressure swing of the sea rods 8 is effected through the springs 11, after a common ratchet bracket 13 attached to a shaft 12 is swung out of the ratchet bars 14 of the sea rods 8. The return of the sea rods 8 to the resting layer shown is effected jointly by a return rod 15, which is supported by sea rod segments 16, which by means of a thrust rod 17 in a corresponding manner and at a certain time are moved by cam discs mounted on the main drive shaft 18.

Genom installningsorganens installning i motsvarighet till det siffervarde, som skaIl installas, eller vid uttagning av summavardet i motsvarighet till de i raknehjulen inneslutna vardena bringas typsegmenten 6 via mellanhjulen 3 till trycklage med motsvarande typer. Vid trycksvangningen och atersvangningen av havstangerna 8 fasthallas typsegmenten medelst tandningarna 4 pa kant och icke visat satt i sitt installda lage darigenom, att de samverka med vid havstangerna 8 lagrade sparrklinkor 10, med vilka de sta i ingrepp, sa lange de aro utryckta ur mellanhjulen 3. By installing the installation means corresponding to the numerical value to be installed, or by removing the sum value corresponding to the values enclosed in the rake wheels, the type segments 6 are brought via the intermediate wheels 3 to a pressure bearing with corresponding types. During the pressure swinging and re-swinging of the sea rods 8, the type segments are held by means of the teeth 4 at the edge and not shown in their installed position by cooperating with ratchet clamps 10 stored at the sea rods 8, with which they engage, as long as they are pushed out of the intermediate wheels 3. .

Nolltrycksstyrningen, dvs. regleringen av avtrycket av alla de nollor, som aro belagna till hOger om ett till vardena 1-9 instant typscgment 6 och forhindrandet av avtrycket av nollorna till vanster mu det hogsta pa eft varde 1-9 installda installningsorganet, genomfores pA kant satt medelst overbryggningsorganen 19, vilka firo svangbart lagrade pa. en gemensam stang 21. Overbryggningsorganen sta. vart for sig under inverkan av en dragfjader 22 och sammanhanga med varandra genom overlappningsansatser 23, vilka aro sa anordnade, att de overlappa det narmast till hoger belagna overbryggningsorganet vid den smala kanten 24 och medtaga detta, nar overlappningsansatserna 23 forflyttas nedat. The zero pressure control, ie. the regulation of the imprint of all the zeros which are coated to the right of one of the values 1-9 instant type segment 6 and the prevention of the imprint of the zeros to the left of the highest of the installed means after 1-9 installed are carried out on the edge set by means of the bridging means 19 , which firo pivotally stored on. a common rod 21. The bridging means sta. individually under the influence of a tension spring 22 and connected to each other by overlapping shoulders 23, which are so arranged that they overlap the nearest to the right-hand bridging member at the narrow edge 24 and include this when the overlapping shoulders 23 are moved downwards.

Overlappningsansatserna 23 samverka samtidigt med den ovre anden av sin sparransats 25 med inskarningar 26 i havstangernas 8 utliggare 27. Nar en sparransats 25 ingriper I det till denna horande urtaget 26, kvarhalles den ifragavarande havstangen 8 vid frigivningen genom sparrbygeln 13, sa att ett avtryck av den installda typen av typsegmentet 6 icke kan forekomma. The overlapping lugs 23 co-operate simultaneously with the upper spirit of their ratchet 25 with incisions 26 in the outriggers 27 of the sea rods 8. When a ratchet 25 engages in the associated recess 26, the sea rod 8 in question is retained upon release by the ratchet bar 13, so that an imprint of the installed type of the type segment 6 cannot occur.

Varje overbryggningsorgan 19 ar dessutom forsett med ett ursprang 28, som samverkar med en aterhallningsstang 29 av en pa en axel 31 svangbart lagrad riktbygel 32. Rikt bygeln kan med en riktskena 33 ingripa i mellanhjulen 3 vid en tidpunkt, vid vilken dessa aro utriktade med typsegmentens tandningar 4 i de installda lagena. Each bridging member 19 is further provided with an origin 28, which cooperates with a retaining rod 29 of a guide bracket 32 pivotably mounted on a shaft 31. The straight bracket can engage with a guide rail 33 in the intermediate wheels 3 at a time at which they are aligned with the type segments. teeth 4 in the installed layers.

Riktbygelns 32 svangningsrorelse overfores genwn en rullhavstang 34, som Ar svangbart lagrad pa en fast anordnad axel 35 och genom rullar 36 svanges tram och tillbaka genom pa huvuddrivaxeln 18 belagna kurvskivor 37, 38. Om riktbygeln 32 befinner sig i det i fig. 1 visade, mellanhjulen 3 frigivande laget, befinner sig aterhallningsstangen 29 ovanfor utsprangen 28 och kvarhaller overbryggningsoragnen 19 mot verkan av fjadern. 22 i det nedre svangningslaget, i vilket sparransatserna 25 Arc belagna utanfor urtagen 26. Slutligell ar varje overbryggningsorgan 19 f6rsett med en avkanningsansats 39, vilka samverka med installningsorganens 2 nedre smalyta 41, 42. Mellan avkanningsansatsen 39 och utspranget 28 ar varje oVerbryggningsorgan forsett med ett urtag 43 och en suedyta 44. The pivotal movement of the directional bar 32 is transmitted through a roller sea rod 34, which is pivotally mounted on a fixedly mounted shaft 35 and through rollers 36 pivots are pivoted back and forth through cam plates 37, 38 located on the main drive shaft 18. If the directional bar 32 is in the position shown in Fig. 1, the intermediate wheel 3 releasing the team, the retaining rod 29 is located above the projections 28 and retains the bridging device 19 against the action of the spring. 22 in the lower pivot layer, in which the spar grooves 25 Arc are located outside the recesses 26. Finally, each bridging member 19 is provided with a scanning shoulder 39, which cooperates with the lower narrow surface 41, 42 of the installation members 2. Between the grouting shoulder 39 and the projection 28 each bridging member is provided with a recess 43 and a suede surface 44.

Den beskrivna anordningen arbetar pa filljande salt. Vid maskinens i fig. 1 visade vilolage befinna sig saval sparransatserna 25 ur ingrepp med havstangernas 8 urtag 26 som avkanningsansatserna 39 ur kontakt med installningsorganens stegformiga ytor 41, 42. Installningsorganen kunna pa ovannamnda salt obehindrat foras till installningslage, utan att hansyn tages till nolltrycksanordningen. Efter derma installning utriktas och sparras installningselementen i sitt installda yardelige I borjan av drivaxelns 18 rotation via rullhavstangen 34 medelst sparrskenan 33. Vid den darvid foljande svangningen av riktbygeln 32 medurs lamnar stangen 29 samtliga utsprang 28 pa overbryggningsorganen och sistnamnda kunna darefter forflytta sig uppat under verkan av sina fjadrar 22. Kommer darvid avkanningsansatsen 39 till anliggning mot den upphojda delen 42 av smalytan hos sitt installningsorgan, stoppas svangningsrOrelsen av detta overbryggningsorgan, innan dess sparransats 25 gar i ingrepp med urtagningen 26. Till foljd air overlappningsansatserna 23 kvarhalles samtidigt aven samtliga till hoger om det tankta stallet belagna overbryggningsorgan i sitt havstangen 8 frigivande lage, savida installningsorganen resp. typsegmenten 6 befinna sig i foliage. Vid de andra, till vanster om det hogsta laget, i viIket en installning av vardet 1-9 har f5retagits, belagna overbryggningsorganen 19 kunna avkanningsansatserna 39 forfl3rttas i riktning mot de stegformiga delarna 41 av installningsorganens nedre smalyta, varvid dessas sparransatser 25 komma i ingrepp med urtagningarna 26 (fig. 2) och darigenom sparra havstangerna 8 i deras vilolAge, sa att sistnamnda icke utsvanges genom sina fjadrar 11, nar de friges av sparrbyglarna 13 vid den fortsatta rorelsen ay axeln 18. Ett avtryck — —3 av nollorna i dessa lagen, pa vilka de ifragavarande typsegmenten 6 aro installda, kan dad& icke genomforas. The described device operates on filling salt. In the resting position of the machine shown in Fig. 1, both the spar rungs 25 are out of engagement with the recesses 26 of the sea rods 8 and the sensing rungs 39 are out of contact with the step-shaped surfaces 41, 42 of the installation means. The installation means can be unimpeded on the above-mentioned salt to the installation layer. After this installation, the installation elements are aligned and locked in their installed yard at the beginning of the rotation of the drive shaft 18 via the roller sea rod 34 by means of the ratchet rail 33. In the subsequent pivoting of the guide bar 32 clockwise, the rod 29 leaves all projections 28 on the bridging means and the latter can then move upwards. of its springs 22. If the sensing shoulder 39 then abuts against the raised part 42 of the narrow surface of its installation member, the oscillating movement of this bridging member is stopped before its sparing sleeve 25 engages with the recess 26. At the same time all the overlapping shoulders 23 are retained to the right. about the tanked stable coated bridging means in its sea rod 8 releasing layer, savida installation means resp. type segments 6 are in foliage. At the other, to the left of the highest layer, in which an installation of the value 1-9 has been carried out, the covered bridging means 19 can be moved by the sensing shoulders 39 towards the stepped parts 41 of the lower narrow surface of the installation means, their sparing means 25 engaging the recesses 26 (Fig. 2) and thereby spar the sea rods 8 in their resting position, so that the latter are not swung out by their springs 11, when they are released by the rafters 13 during the continued movement on the shaft 18. An imprint - —3 of the zeros in these layers , on which the type segments 6 in question are installed, can not be implemented.

Efter tryckningsoperationen aterfores de utsvangda havstangerna 8 medelst aterfiiringsstangen 15 till stha utgangslagen, i vilka de sparras genom den ay haystangernas snedytor 45 upplyfta sparrbygeln 13. Darefter aterfSres riktbygeln 32 till det i fig. 1 visade frigivningslaget mederst rullhaystangen 34. Darvid aterfOres genom anliggning av aterhallningsstangen 29 mot snedytorna 44 samtliga Overbryggningsorgan till det i fig. 1 visade vilolaget, i vilket samtliga installningsorgan 2 ater frigivas, och slutligen sker aterstallningen av de installda installningsorganen och typsegmenten till nollage, vilket genomfores utan paverkan av overbryggningsorganens 19 aykanningsansatser 39. After the printing operation, the swung out sea rods 8 are returned by means of the return rod 15 to the initial layers, in which they are locked by the ratchet 13 raised by the oblique surfaces 45 of the hoist rods. 29 against the inclined surfaces 44 all bridging means to the resting layer shown in Fig. 1, in which all installation means 2 are again released, and finally the installed installation means and type segments are restored to zero, which is carried out without the influence of the bridging means 19.
