MECHANISM OF CUTTING PLANAR FORMATIONS

The invention concerns a mechanism for cutting planar formations, in particular for cutting printing products, with a circulating cell wheel, whose takes up each compartment a planar formation. A such, from the DE-PS Nr.308330 well-known mechanism exhibits a only one stationarily s arranged knife, which cuts the parts of in this inserted books, about a turning steel, understanding radially over the compartments, similarly. Thus only in a certain and closely limited place at the extent of the Zellenrades and also only one cut is cut is accomplished after the other one. This leads inevitably to a rnckweisen function, completely apart from the fact that the largest part of the orbital period of the compartments of the well-known mechanism remains unused, if one does not consider probably compellingly necessary supplying of untrimmed books and removing from circumcised books. The invention preserves with this state of the art the task at the basis to train a mechanism eingaugs of the indicated kind in such a manner that it permits higher peripheral speeds of the Zellenrades and furnishes thus higher cut achievements, without it would be necessary to limit for the particulars is cutting process temporally. During the suggested mechanism a cutting process is to take place at the same time in several compartments. For the solution of this task the invention consists essentially of that in each compartment an abbey! firm Gegenmesser and a bewegllches Schneidmesser are arranged, for whose movement a running along mechanism is intended, a cam common for all Schneidmesser is assigned to which, and that in each compartment a feed feature, e.g. a conveyor is arranged and with this cooperating pressing roles, which feed feature is propelled alternating to the manipulation of the Schneidmessers, in order to supply the Flächengebllde to the measurers and to away-supply the circumcised planar formation of these. Contrary to the above-mentioned, well-known mechanism in accordance with the invention each compartment of the 2s Zellenrades therefore likewise rotated those equipped with a pair by measurers (a compartment-firm and a mobile), so that the gumption course of each NIesserpaares can be distributed temporally on a larger part of the orbit, or, to limit with other words, so that the peripheral speed of the Zellenrades can be increased, without the NIinimalzeit necessary for the cutting process. Two Ausführnngsbeispiele of the invention article are below described on the basis the designs more near. It shows: Fig.i a schematic opinion of a Zellenrades with drive, Fig.2 a simplified cross section by the one execution form, whereby are levels the named A, B and C designated sectors in this figure of cuts with the same letters in Fig.1, Fig.3 in similar representation as Fig.2 a cross section by the other execution form, Fig.4 in 3s increased yardstick and on average a Ausführungsvarlante of the feed feature along the line IV-IV of the Fig.SA or self-service, Fig.5A and self-service simplified cuts along the line V-V of the Fig.4, Fig.6 to 9 views of compartments of the mechanism, radial in strongly simplified representation, in accordance with Fig. 2 in different operating positions, whereby only in each case those construction units are schematically indicated, which are effective straight, and Fig.10 likewise a-bucks in simplified representation radial into not necessarily directly neighbouring compartments of the mechanism in accordance with Fig.3 for explanation their impact. The mechanism represented in Fig.1 --10-- is on a base --11-- constructed, on that two Trägrahmen --12, 13-- are ahgestützt, which exhibit for their part the shape of a portal. The openings in the support frames represented in side view --12, 13-- are not visible in Fig.1. Between the support frame --12, 13-- extend a number of - in the available case four - waves, from those 4S in Fig.1 a lower wave --14-- and an upper wave --15-- are visible. The remaining waves are on same height, however in Fig. 1 side cleared away on that the viewer. The ends of the waves --14, 16-- are in camps --16-- stored, those for their part in the Tragrabmen --12, 13-- are fastened. Both on the waves --14, 15-- and on the not visible waves one pair each roles sits. On the wave --14-- this is the roles --17--, and on the wave --15-- the roles --18--. These roles are S0 at their faces with flanges --19-- provided. Between the roles is a horizontal lying cell wheel --20-- supported, which essentially appears in Fig.I as rectangle. The cell wheel --20-- thus by means of the roles one holds and is around the dash-dotted suggested axis of rotation --21-- swivelling stored. The compartments of the Zellenrades --20-- are open at its two faces, while the cell wheel within the range of its Stlrnseiten by Halterlnge --22, 23-- is enclosed. The guard rings --22, 23-- carry ever a run ring --24, 25--, on those the roles --17, 18-- between the flanges --19-- unreel. On the wave --14-- a chain wheel in addition sits --26--, that over a chain --27-- and over a reduction gear --28-- with an engine --29-- is coupled. Thus the cell wheel can by switching on of the engine on --29-- over the roles --17-- in turn to be shifted. In place of the roles --17-- can with flanges provided gear wheels be intended and in this case would be the run rings with external teeth provide. The waves --14 and 15--, as well as the not waves visible in Fig.1 extend by rings --30, 31-- and by a Ringsegment --32-- and are likewise swivelling stored in these. The rings --30, 31-- as well as the Ringsegraent --32-- surrounded with play the cell wheel --20-- and carry, as to be described will still have, at their inside a cam and/or at its face a friction segment, which for the manipulation in the compartments of the Zellenrades existing, of the construction units below still which can be described to serve. It is to be noted that the rings --30, 31-- and the Ringsegment --32-- by the circumstance that two or more of the waves --14, 15-- by it through lead, against a lVlitdrehen with the cell wheel --20-- are secured. It is now taken on the Fig.2 to 5 purchase. The cell wheel points a hollow hub --33-- up, at their lateral surface in regular angle angles radially are away and under itself equal trained walls --34-- are fastened, so that between two neighbouring walls --34-- in each case a compartment --35-- develops. With the available execution forms are altogether twenty-four compartments --35-- available. Each of the compartments --35-- that serves in the course the circulation it the Zellenrades as the admission of a Flächengebüdes, --20-- to cut is. For this purpose is also each of the compartments --35-- with a pair measurer and in addition a pair Preßbacken exhibiting cutting tool as well as with a feed feature equips, which leads the Flächengebüde away which can be cut to the cutting tool and from this. The execution form of the Fig.2 and 5a (as well as differ 6 to 9) from those the Fig.3, 5b and 10 only thereby that the first to the axis of rotation --21-- the Zellenrades --20-- right-angled running cuts and latters to the axis of rotation --21-- the Zellenrades --20-- parallel implements running cuts. For the functionally corresponding parts the same reference numbers are selected from there whereby the reference numbers that the first execution form no, those the latter however an apostrophe slow-acting. Below the cutting tools are on the one hand and the feed feature on the other hand descriptive in the order. The Fig.2 (sector A) and the Fig.7 it is to be taken that in each compartment --35-- a pair Preßbacken --36-- , those are arranged over a tap --37-- articulated at the ends of a cross beam --38-- (Fig.7) is fastened, whereby the cross beam at a rocker --40-- , those is fastened to a coupling point --39-- the close one --33-- is tiltable stored. The Gegenbacke of the Preßbacken --36-- is by this course-turned surface of the neighbouring wall --34-- formed. The free end of each rocker --40-- that is connected from one at the rocker with a linkage gearing, --40-- linked ouple --41-- and from one with these articulated connected bell cranks --42-- , its vertex exists to a coupling point --43-- a bearing centre --44-- is tiltable stored, which at that the Preßbacken --36-- cleared away side of the neighbouring wall --34-- is fastened. At its other free end the bell crank carries --42-- a following role --45--, those by a feather/spring in constant interference with radially inward an arranged cam, not represented more near --46-- , those is held at the inside of the ring --31-- is trained. The cam --46-- it is in such a manner arranged that the Preßbaeken --36-- in the course of a revolution of the Zellenrades --20-- a Schlleßhub as well as an opening stroke would drive out. On the assumption, the cell wheel turns in the direction indicated in Fig.2 as the arrow 47, leads thus the Preßbacken --36-- with the run of the sector a closing stroke designated in Fig.2 with A out. The Fig.2 (sector B) as well as the Fig.8 it is to be taken that each compartment --35-- two mobile Schneidmesser --48-- as well as two Gegenmesser --49-- (Fig.8) exhibits. The rain-gauges --49-- are in for each s0 of a radially running slot --50-- sunk, those fastens in as Gegenbacke for the Preßbacken --36-- serving surface of the wall --34-- is trained. From Fig.8 it follows that the cutting edges of the cooperating measurers toward the closer in each case faces of the Zellenrades --20-- directly the Preßbacken --36-- are pre-aged arranged. The Schneidmesser --48-- are ever at a a longitudinal fold the rocker --51-- trained, einerends to on] enkpunkt --39-- the rockers --40-- the compartment preceding in Umlaufrlchtung seen --35-- are linked. At their other free end are the rockers --51-- the Schneidmesser --48-- over a ouple --52-- articulated with an end of a bell crank --53-- connected, its 8cheitel by means of a tap --54-- at a bearing centre --55-- is tiltable stored. The bearing centres --55-- are at that the Preßbacken --36-- cleared away side of the wall --34-- to the following compartment --35-- fastened. At its free end each bell crank carries --53-- a Folgeroile --56--, those by a feather/spring in constant interference with radially inward an arranged cam, not represented more near --57-- held, those is for its part at the inside of the ring --30-- is trained. The ouple --52--, the signs] levers --53-- and the following role --56-- form the mechanism for moving a Schneidmessers. If in Fig.1 of two rings --30-- are represented, so because each of the rockers --51-- and thus each of the Schneidmesser --48-- over an own following role --56-- is operatable. It will be still shown that for the other execution form only one cam is necessary, because in each compartment only one pair measurer is intended. The cam --57-- it is now in such a manner trained that the Schneidmesser --48-- in the course of a revolution of the Zellenrades --20-- a gumption movement and back would drive out, and regarding the cam --46-- in addition in such a manner that the gumption stroke begins only then if the Preßbacken --36-- their closing position reached. The part of the cam visible in the sector B of the Fig.2 --57-- covered both the gumption stroke, that with reaching the internal apex --58-- the cam --57-- terminated, and the opening stroke, that is direct itself at the Scheiteipunkt --58-- attaches. With here described remark examples is intended that the direction of motion, in which the planar formations are supplied to the cutting tools (Preßbacken and measurers) and led away by these, parallel to the axis of rotation --21-- runs. Of course it is possible, these planar formations also in radial direction into the compartments --35-- to introduce. Is from there below first on the Fig.1, then on the Fig.2, 4 and 5a as well as 6 and 9 purchase taken. In Fig.1 it is broken represented that the mechanism --10-- concerning division and number of revolutions a cathedral line wheel --20-- similar supply wheel --59-- is upstream, that the planar formations --60-- - here printing products - radially and separately to be supplied. Of the supply wheel --59-- become the printing products into the compartments --35-- the Zellenrades --20-- toward the arrow 61 (Fig.1) pushed in. As soon as the printing products one of the compartments --35-- reached, arrive they into the range of one in axial direction to gradually working feed feature, now in particular on the basis the Fig.4 and 5a to be described rope. This Vorschubeinrlchtung points a thin, propelled conveyor --62-- up, that in each wall --34-- , and its promote-active Trum is inserted to the Preßbacken around weniges of that --36-- course-turned side of the walls --34-- manages. The conveyor --62-- is at his beginning and at his end ever around a freely swivelling guide roller --63, 64-- led, and between them a Antriebswalze is intended. Außerdom is the conveyor --62-- around further, freely swivelling guide rollers--66--led, which serve to lead the process of the conveyor in such a manner that it not in conflict with in the compartment concerned --35-- arrives to existing cutting tools (Preßbacken and measurers). In Fig.5A is by means of the guide roller --66-- the conveyor --62-- under the Gegemnesser --49-- passed through. Each of the Antriebswalzen --65-- (Fig.4) sits on bearing bushes self-lubricating in two --67, 68-- inside the wall --34-- swivelling stored wave --69--, itself right-angled to the axis of rotation --21-- the Zellenrades --20-- over the end of the wall concerned --34-- outside extends. At their free end is each of the waves --69-- with a friction wheel --70-- equipped, that with one on the 4s face of the Ringsegmentes --32-- trained friction segment --71-- zusarmnenwirkt. The lining up wheels --70-- and therefore the assigned conveyors --62-- are thus only so long propelled, as the friction wheels --70-- at the friction segment --71-- attack, i.e. in Fig.2 in sector the named C. This sector C essentially extends over that range of the cams --46 and 57--, into this the Schneldwerkzeuge in the compartments --35-- in Offenstellung hold. With each of the conveyors --62-- a sentence of freely swivelling pressing roles works --72-- together, those within the range of the ground of the compartment concerned on a shaft end --73-- are freely swivelling stored. The internal end of the shaft end --73-- is at an arm --74-- fastened, that for his part tiltable on a tap --75-- is stored, which of the ground of the compartment concerned --35-- radially is away. One around the tap --75-- .gewundene feather/spring --76-- has the tendency, the arm --74-- and therefore the Anpre rolls --72-- against the assigned conveyor --62-- to press. It results in sees that essentially from the conveyor --62-- and from the pressing roles --72-- existing Vorsehubeinrichtung in addition does not only serve, the Druekprodukte effectively in longitudinal direction of the compartments --35-- to put forward (so long the friction wheels --70-- in the interference with the friction segment --71-- are), but also around the Druekprodukte in the compartment concerned--35-- to clamp, so long the Preßbaeken --36-- yet in their closing position are not or again their open position reached. By appropriate calculation in particular at the beginning and the end of the friction segment --71-- (Fig.2, sector C) succeeds it thus to bring and this situation remove each printing product accurately into the situation wished for cutting. In addition it is possible, also the same feed feature, at the same time a printing product of the supply wheel, which can be cut--59-- (Fig.1) to draw in and a circumcised printing product of the cell wheel --20-- (in Fig.1 to the right) to discharge. The feed feature for the second execution form (Fig.3, 4, 5a and 10) is essentially is directly developed, as those the execution form described so far, so that a repeated description might be unnecessary. Only the Fig.SB shows a difference in as much as the guidance: the conveyor --62-- more simply than those the Fig.SA is. This therefore, weil' with this execution form the conveyor --62-- the cutting tool handicapped and therefore this auzuweichen also does not need. Likewise the cutting tools of this second execution form are directly trained grundsätzüeh, as with the execution form described first. The Bezugszfffern for each other functionally corresponding components is from there the same, however with an apostrophe ve1 “sees. This meets for the Preßbacken --36r--, for the cross beam --38r-- (Fig. 10), for the rocker --40r--, for the ouple --41t--, for the bell crank --42”--, for the bearing centre --44 '--, for the following role --45 '-- and for the 2s cam --46I-- too. The only difference consists of that the main dimension of the Preßbacken - 36 '-- parallel to the axis of rotation --21-- the Zellenrades --20-- is, while the main dimension of the Preßbaeken --36-- in the remark example of the Fig.2 right-angled to this axis of rotation --21-- , with these Ausführungsferm is the mobile Schneidmesser runs --48 '-- (Fig.10) likewise at the long side of a rocker --51 '-- trained. The rocker --51 '-- is einerends around one of the peripheral end of the wall --34-- radially which are away taps --77-- tiltable stored. The free end of the rockers --51v-- actual as with the rocker --51-- - over the ouple --52t-- to the bell crank --53 '-- coupled, that for his part at the bearing centre --55 '-- is stored. The Wlnkelhebel --53T-- the following role carries at its other end --56 '--, those by a feather/spring in constant interference with the cam -57r, not represented more near-- is held. This cam --57r-- is, contrary to the cam --57--, axially 3s addressed, however likewise to the inside in Fig.1 on the left of appearing ring --30-- trained. In Fig.1 on the right of appearing ring --30-- would not be necessary from there for this execution form. The impact of the descriptive mechanisms results in sees almost automatically in the case of regarding the FiEurenfoige 6 to 9 and/or the Fig.10. In Fig.6 two are toward the arrow 47 itself at the friction segment --71-- past moving compartments visibly. With the lower compartment is the friction wheel --70-- still in the interference with the friction segment --71~, i.e. the feed feature is in the process still effective, the appropriate printing product still is into the situation suitable for cutting to be brought during in the upper compartment the friction wheel --70-- the friction segment --71-- already left, because the feed feature brought the printing product into the desired situation. In the lower compartment of the Fig. 7 the printing product is to be recognized, which stands in terms, by the Preßbacken--36-- 4s become held. In the upper compartment of the Fig.7 the printing product is by the Preßbacken --36-- clamped. In be subordinate to compartment of the Fig.8 is in principle the situation of the upper Abteila of the Fig.7 repetitive. The two mobile longing oath measurers --48-- at the rockers --51-- stand in the term to approach the printing product in the middle compartment of the Fig.8 have the Schneidmesser --48-- the parts of the printing products, those over the Preßbacken --36-- manage, already cut off, in the highest compartment of the Fig.8 are both so the Preßbacken and the Schneidmesser in their opened position, so that the printing product, and in the upper compartment of the Fig.9 represented, by means of the feed feature to the right from the cell wheel --20-- to be discharged can. In the lower two compartments of the Fig.10 a printing product is in terms by the feed feature into the desired situation to be brought which it in the third compartment ven down in Fig.10 holds. In the fourth compartment from downside the Fig.1O has the Preßbacke --36 '-- the printing product jammed, in the next compartment has the Schneidmesser --48 '-- over the Preßbacke --36 '-- understanding part of the printing product cut off, and in the sixth compartment from downside is both Preßbacke --36 '-- and the Schneidmesser --48 '-- in opened position. flodann the feed feature can become again effective (highest two compartments of the Fig. 10). If is erwiinscht, a planar formation --60-- on three sides to cut, only a unit is in accordance with Fig. to build 2 and a refinement in accordance with Fig.3 together in principle. This is easily lo possible, particularly since for such, from two a-preserved existing mechanism the same Vorschuheinrichtung is possible. P A T EN T AT S PRO CIIE: 1.
