Abstract

A folding cylinder 1 has a device for switching between collecting and non-collecting modes of operation and is provided with a fixed cam disc 7 and a cover disc 11 driven by the folding cylinder. The two discs together are followed by rollers 2, 3 on a lever 4 which controls sheet holding or folding mechanism. In order to make switch-over possible while the apparatus is operating and with simple technical means and a small space requirement, a planetary wheel 15 mounted on the end of the folding cylinder, engages both into internal teeth 12 of the cover disc 11 and into a sun wheel 14. The sun wheel can be rotated by a spindle 20 into the positions corresponding to the cam paths for collecting or non-collecting. <IMAGE>

Description

15 20 25 30 35 507 03.6 z Uppfinningen beskrives nedan med hänvisning till ett utför- ingsexempel. Tillhörande ritning visar i schematisk vy ett tvärsnitt genom en enligt uppfinningen utförd omställninge- anordning för samling eller icke-samling hos en falscylinder. 15 20 25 30 35 507 03.6 z The invention is described below with reference to an embodiment. The accompanying drawing shows in schematic view a cross section through a switching device for collecting or non-collecting of a folding cylinder embodied according to the invention.

I falscylindern 1 är på känt, icke visat sätt en axel lagrad, vilken står i förbindelse med hållar- elelr falsmekanismer och på vilken en rullhävstång 4 är fäst, vilken i sin tur uppbär två axiellt i förhållande till varandra förskjutet anordnade kurvrullar 2, 3.A shaft is mounted in the folding cylinder 1 in a known manner, not shown, which is connected to holder or folding mechanisms and to which a roller lever 4 is attached, which in turn carries two cam rollers 2, 3 arranged axially offset relative to each other.

Därvid samverkar den yttre kurvrullen 2 med en fast, via en husdel 5 med en stativvägg 6 förbunden kurvskiva 7 och den inre kurvrullen 3 med en vridbart på en axeltapp 8 hos fals- cylindern 1 lagrad täckskiva 11, som är tvådelad och består av en lagerkropp 9 och en kurvkropp 10.In this case, the outer cam roller 2 cooperates with a fixed cam disc 7 connected via a housing part 5 to a frame wall 6 and the inner cam roller 3 with a cover disk 11 rotatably mounted on a shaft pin 8 of the folding cylinder 1, which is two-part and consists of a bearing body. 9 and a basket body 10.

I falscylindern 1 är vid änden och koaxiellt ett planethjul 15 lagrat, vilket dels griper in i invändiga kuggar 12 i lagerkroppen 8 och dels står i ingrepp med ett i en borrning 13 i husdelen 5 koakiellt roterbart lagrat solhjul 14.A planet gear 15 is mounted in the folding cylinder 1 at the end and coaxially, which partly engages in internal teeth 12 in the bearing body 8 and partly engages with a sun gear 14 coaxially rotatably mounted in a bore 13 in the housing part 5.

Solhjulet 14 är utrustat med ett kuggsegment 17, vars sväng- ningsrörelse i lägena för samling och icke-samling begränsas av ett vid husdelen 5 fäst anslag 16 och i vilket ett drev 21 ingriper, vilket är fäst på en i stativväggen 6 lagrad in- ställningsaxel 20, som på väggens utsida uppbär en klämring 18 samt ett manöverelement 19.The sun gear 14 is equipped with a gear segment 17, the pivoting movement of which in the positions for assembly and non-assembly is limited by a stop 16 attached to the housing part 5 and in which a gear 21 engages, which is attached to a setting shaft mounted in the frame wall 6. 20, which on the outside of the wall carries a clamping ring 18 and an operating element 19.

Genom en även då maskinen är i gång genomförbar extra vrid- ning av den ständigt av falscylindern 1 drivna täckskivan 11 i förhållande till den fasta kurvskivan 7 roterar täckskivan 11 i det av ett av anslagen 16 bestämda läget för samling med sådan hastighet, att den periodiskt täcker kurvskivans 7 manöverområde för kurvrullen 2, varvid rullhävarmen 4 på- verkas endast efter samling av produkterna medelst motsvaran- de frigivning av kurvrullen 3, medan täckskivan 11 däremot i det av det andra anslaget bestämda läget för icke-samling roterar vinkelförskjutet i förhållande till kurvskivan 7, så 10 15 20 3 507 036 att kurvskivans manöverområde för kurvrullen 2 vid varje rotationsvarv hos falscylindern 1 förblir fri, varigenom ingen samling av produkterna sker.By means of an even rotatable extra rotation of the cover plate 11 constantly driven by the folding cylinder 1 relative to the fixed cam disc 7 even when the machine is in operation, the cover plate 11 rotates in the position determined by one of the stops 16 for assembly at such a speed that covers the operating area of the cam 7 for the cam 2, the roller lever 4 being actuated only after assembly of the products by corresponding release of the cam 3, while the cover 11 in the non-assembly position determined by the second stop rotates the angular displacement relative to the cam 7, so that the operating area of the cam disc for the cam roller 2 at each rotational revolution of the folding cylinder 1 remains free, whereby no collection of the products takes place.

I utföringsexemplet styres produkterna exempelvis av punktur- nålar, som håller framkanten mot falscylindern, via rull- hävstången 4, medan den icke visade falskniven utan styrning ständigt skjuter ut förbi omkretsen, så att vid samlade produkter hålles falsklaffarna hos den icke heller visade falsklaffcylindern öppna synkront med falscylindern 1, så att falsning undvikes.In the exemplary embodiment, the products are guided, for example, by puncture needles which hold the leading edge against the folding cylinder, via the roller lever 4, while the folding knife (not shown) constantly protrudes past the circumference, so that in the case of collected products the folding flaps of the folding cylinder (not shown) with the folding cylinder 1, so that folding is avoided.

Vidare finns även möjlighet till styrning av ytterligare falsmekanismer genom att det för manövrering av dessa via en särskild rullhävstång bredvid kurvskivan 7 och täckskivan 11 finns en ytterligare kurvskiva resp. täckskiva, som är vin- kelförskjutet anordnad i motsvarighet till anordningen av de olika falsmekanismerna i falscylinderns omkretsriktning.Furthermore, there is also the possibility of controlling additional folding mechanisms in that there is an additional cam disc resp. cover plate, which is angularly offset arranged in correspondence with the arrangement of the various folding mechanisms in the circumferential direction of the folding cylinder.

Det är även tänkbart att med samma effekt anordna en andra omställningsanordning vid den motsatta änden av falscylindern för manövrering av andra fals- resp. hâllarmekanismer.It is also conceivable to arrange with the same effect a second adjusting device at the opposite end of the folding cylinder for operating second folding resp. holding mechanisms.
