PEYREBRUNE FORM ROLLER SETTING AND TRIPPING MECHANISM Filed May 22, 1947 April 21, 1953 3 Sheets-Sheet 5 INVENTOR. Henri E. Peyrebrune relation tothefplatef 1 Patented Apr. 21, 1953 FORM ROLLER SETTING AND TRIPPING MECHANISM Henri E. Peyrebrune, River Forest, 111., assignor, by mesne assignments, to Miehle PrintingPress and Manufacturing Company, Chicago, 111., a
corporation of Delaware Application May 22, 1947, Serial No. 749,803 4 Claims. (01. 101-352) This invention relates to inking mechanism for sheet fed printing presses. It more specifically pertainsto improved means whereby the form rollers can be set with respect to the printing plate for the purpose of establishing the desired contact relation therewith, and whereby these rollers can be tripped away from the plate either by hand or automatically, in order to interrupt the supply of ink thereto under certain conditions which may arise while a press is running.
In the operation of inking mechanism of the 'class to which my invention relates, the ink is applied to a printing plate or form by means of a series of form rollers which receive a supply of ink from an ink distributing roller system.
Such rollers are set'for the desired contact relation with the plate by manually operated means such as set screws or the like.
Under certain conditions which occurduring the operation of sheet fed printing presses, for
' instance when a sheet is misfed, the form rollers must be tripped off the printing plate in order to interrupt the supply of ink thereto until normal feeding conditions of the sheets are again established. Heretofore, such tripping was accomplished by means independent of the roller setting means, and all the form rollers of a series were tripped off and on the printing plate simultaneously while passing over the gap provided in a plate cylinder for purposes well known in the art. With the introduction of improved sheet feeding and registering methods which permit of a smaller cylinder diameter and a gap therein of reduced span, for accommodating a given size sheet, not all of the form rollers pass the gap at the same time and therefore the rollers cannot be tripped off and on the cylinder simultaneously.
In view of this I propose to trip the form rollers off and on the printing plate in sequence,
preferably in pairs.
Stating the principle of the invention broadly, it consists in'the provision of mechanism whereby form rollers,which apply the ink to the printing plate, can be positively moved into their ink applying position and tripped therefrom sequentially and by the same means whereby the setting of the form rollers with relation to the printing plate is accomplished.
Another accomplishmentandobject of themvention includes ,the provision of eccentric means for setting the form rollers with relation to a cooperating roller or rollers of the ink distributing system.
An additional object of the invention resides in the provision of means whereby the form rollers may be automatically tripped, preferably sequentially, and in pairs, by the intermediary of the same eccentric means whereby the form rollers are set with relation to the plate and by the the setting and tripping means for th form rollers in such a manner that when the rollers are tripped from the printing plate they remain in proper contact relation with their respective associated distributing roller or rollers.
Another object resides in the provision of eccentric means whereby the form rollers are set for contact relation with their associated ink distributing rollers. j
Still further objects and advantages of my invention will become apparent from the following description and appended claims read in conjunction with the accompanying drawings in which,
Figure 1 is a roller diagram which illustrates the general arrangement of the various elements included in the inking mechanism of a printing press;
Figure 2 represents schematically the relative position of a series of form rollers in operative position with respect to a printing plate carrier, preferably a cylinder, and to the associated ink supplying or distributing rollers, together with the eccentric means whereby the form rollers are in partial cross section those relative parts This I propose to carry into effect preferably by means of eccentric adjusting means arranged so that the same eccentric means, whereby the mm rollers are set with relation to the printing the rollers with plate, are used also for tripping whereby the setting with relation to a form roller may be accomplished;
Figure 5 illustrates the position of part of the operating means and shows all the form rollers tripped from the printing plate, and
' v Figure 6 represents a diagrammatic showing of the mechanism associated with the eccentric means whereby the form rollers are automati- 1 Cally-and sequentially moved into and out of roller H whereby a supply of ink is conveyed from the fountain roller to a vibrator roller 12 and with which latter are associated-anumber of rider rollers such as I3 and ink-up roller From the vibrator roller l2 the, ink is then. con.-
veyed by means of additional rider roller I3;,vi
brating drum l5 so that a thin filmoi-ink is eventually applied to the distributing rollers I65:
and I! which are in contact with th form roll: ers l8 whereby the ink is finally appliedtothe printing plate I8 carried by the plate cylinder-2B. The composition rollersIare shown in heavy lines,
. whereas the metalrollers.-such as I 2, 5, l 6.. and
I1. areshown in thinjlin'es. Y N I It will be noted that m. Figures.2..and..5,:, only part ofthe inking mechanism frame. 21. isjshown in full lines and that only somezofitherollersc which comprise the ink distributingrroller unit are shown, these are indicated in brokenlines. Furthermore, the printing plate l8, together with its support. 20, preferably. in the form-of. a. cylinder,v are,.alsoindicated in broken. linesiior the purpose. of a. clearer. showing of-those. parts. actually involved in the invention. Moreover, in Figures 6 only thoseiparts-are shown infull lines which constitute the. means whereby the. form rollers-are tripped from their ink applying. position when so required.
It shall also. be-understoodthat thepartsill'ustrated in Figures 2. and 5, and some of thoseindicated in Figure 6, as being applied. to the. side frame member 21-, are duplicated onthe.frame member 22 at the opposite side of theinking .mechanism, see Figure 3, and. that the manner ofoperation is identical at both-sides. I
Referring nowto Figure2 of the drawings, the form rollers |8- are supported, in. their respective sockets 28, 29, and 3! which are-providedon the arms 32, 33, 34 and 35. The latter are held inttheir. positions with relation. to'the frame 2| by means of a retainingring. sector 31 in av manner that thelower ends of. these arms may movefreely to follow any adjustment imparted tothem as will be explained later with reference toFi'gure 4. The sector 31.ispreferably secured'to. the side frame. 2| by meansjofbolts 38. The-.iree ends oi the. arms 3zktoi85i are: carried by means. 0)? eccentric bearings 41 to 44 inclusiveina manner that by the actuation of these eccentrics, the arms 32 to 35 and therewith theform rollers I 8 may be moved downor up for the purpose, of contacting the form rollers with or tripping. them from the plate [9 on the cylinder 20;
The adjustment of the form rollers- [8 may be effected manually by means of hand levers 41 two of which are illustrated in Figure 2 and which are mounted for engagement at the outer side of the framez I, see Figures 3-and 4. 7
It will be understood with reference to Figure 4, that upon rotation of the eccentric 42 by means of the hand lever 41; or automatically as will be explained hereinafter,- the arm. 33 will. bemoved upor down, as the case maybe, in order :toeither trip the roller Hi from the. printing plate, or lower it into contacttherewith, andithat during such movement the lower. end of the-arm 33 can ,slide'freely between the frame 2| and-the retainingring sector 31, suflicientclearance-being provided for such movement between the frame and said sector.
For the purpose of establishing the desired contact pressure between the form rollers I8 with relation to their respective distributing rollers I6. and. H whichare. mounted on fixed axes, links 48 to 5! are pivoted to each one of the arms 32 to 35. The outer ends of these links are supported in eccentric bearings such as are indicated at52 and 53 in Figure 2. This arrangement applies, of course also, to the other form rollers. Itwhichhave contact relation with the distributing, roller 'l 1.
This. adjustment is preferably accomplished by suitable. hand. levers such as at 54 and 55 .which are also operable from the outer side of frame members 2| and 22. It will be seen thereforethat with the arrangement so far described independent manual adjustment of the form rollers withrelationto theprinting. plate-as. :well as withrelation-to the. distributingrollers I Blandl'! can'beefiected; r
The.plan..- view as. presentedin: Figure 3,. and the. sectional view given. in Figure. 4, are. essentially limited totheshowingof themanuallyoperatedroller setting means such as.v are represented. in. Figure 2, theautomatic tripping mechanism for the; form rollers having. been. intentionally omitted.from.Fig'ures.2' and! inclusive andare illustrated'in Figures 5 and 6..
- Moreover, in Figure.-4,-.th cross section-is taken along. such. lines as; willlillustratev therelative arrangement of merely one form roller supporting arm and the eccentricmeans whereby the latter is actuated. The eccentric 1-2 isishown' all the way. up, consequently the. roller 18' is. tripped oil the plate I 9, aiposition indicated in Figure-5.
Referring now tov the detail-construction depicted in. Figure 4, it: will be seen that thehand lever 4.1; whereby the eccentric 42is"actuated',.is applied to the free'endofthe eccentric carrying shaft 56' which projects "through the; side frame 21. A preferred'm'ounting for'thisand' allother levers-which have thefunctionof adjusting an e'ccentricby'hand'; preferably includes set pins 58 driven into or otherwisesecured 'to the shafts which carry the eccentric bearings. The levers are'positioned by means of'these set'pin 58and are secured into their positions by applying a nut 59 to the threaded ends of said shafts;
The form rollers are preferably, held within their respective 'socketszand are supported therein by means of anti-friction bearings 61 and'62 mounted at'the ends of saidrollers, see Figures, the former" one of which. bearings may be retained against lateral. movementwithin a groove 64 formed'in the socket 29 oflever 33, whereas the bearing 62 at the opposite end of. the form rollers is not restrained against any lateral movement within its supportin socket.
The-links48 to 5| inclusive are preferably pivoted to the arms. 32 to 35 respectively by means of a threaded stud 66 which passes through a bore fii provided in the lower endof said links and which projects through bore 68 formed in said arms in alignment with the axis of the form rollers l8; The studs [it have'a shoulder 69 which bears against the roller socket arm- 33, and the stud is secured thereto by means of a nut 10.
InFigure 5-, which illustrates part of the mechanism whereby the form rollers l8 are tripped automatically with relationto the-plate [9-, said form rollers are indicated in their-position when 'they are tripped from the plate, a position which theyassumei upon rotating the eccentrics 4Ito 44 inclusive to the extent that thethick portion of the eccentricsisall the way up shown in .this figure. V p
' According to the preferred arrangement of the operating elements illustrated in Figure 5, the form rollers I8 are tripped in pairs from the plate 19 by moving about the pivotal center of the links 48, 49; etc; thereby changing their angular'relation while remaining in contact with their associateddistributing rollers I6 and .II.:..' As shown in this. figure, the eccentricsil' an 42 are interconnected by a link '15; connecting rod "16 and the arm 11 of a bell crank lever- 18.- To
the arm "I9 of this bell crank lever is pivoteda "connecting rod 80, the outer end of-whlchglink :on a rock shaft 82.
is in turn pivoted to a link 8l rigidly mounted he eccentrics'43 and 44 are similarly con- :nected by a system of links 83, connecting rod 84, bell crank lever 85, connecting rod 86 and '1ever8'I which latter is rigidly secured'to a rock shaft 88'. v I
It will be understood therefore that upon rock ing of link 8I by means of the shaft 82, in an .pa'nti-clockwise direction, from its position shown in Figure 5, the eccentrics M and 42 will be I rotatedito assume the position depicted in Figure 2 :where the rollers I8 are in contact with the plate: I9, while maintaining contact howeverwith 1 their associated distributing roller it.
In Figure 6 I have illustrated a preferred mechanlsm whereby the rollers I 8 can be tripped automatically with'respect to the printing plate I9 through the intermediary of the lever and link arrangement illustrated in Figure 5. This mechanism may include a closed cam 90 having a roller track BI, tripping levers 92 and 93 on the inwardly extending arms of which are carriedcam rollers 94and 95, respectively. These rollers ride, within the cam track 9| and the levers 9'2 and 9.3 are pivoted to studs 91 and-98 respectively and are rocked about these studs by the motion imparted to them by the cam rollers 9-4 and 95 during the rotation of the cam 90 as will be readily understood.
Each one of said levers 92 and 93 is provided with suitable recesses and with bearing faces 99 and I for engagement by tripping dogs IM and I02 which have corresponding bearing faces arranged for engagement with the faces 99 and I00, for the purpose that will be explained more fully hereinafter.
The dogs IM and I02 are pivoted at I84 to- I links I and I06 respectively in a manner that said dogs can be rocked in order to move their bearing faces into and out of engagement with the. bearing faces 99 and III!) of saidtripping levers.
To the pivots I04 are also applied connecting I rods I01 and I08, the former having in turn pivpurpose of holding the link and rod connections and therewith the form rollers I8, either in tripped off or on positions;
To the dogs IM and IE2 "are also pivotally attached connecting rods -I I2 and H4 which in turn are pivoted to one arm of hell crank'levers 'II5and lI6respectiv'ely. For the purpose 'ofmaintaining these dogs in their respective positions, I preferably apply .twoway spring means, notshown, to these connecting rods.
To the other'arms of said bell crank levers are pivoted connecting rods Ill and H8 respectively which extend to conventional automatically or vmanually operated tripping and set up means, the
purpose'of which is well known in the operation of printing presses and similar machinery where rollers or cylinders are to be tripped for various reasons out of their operative positions. J
"As indicated in broken lines in Figure 6, tha
pair of form rollers I8 which cooperates with the distributing roller I6 is indicated as being in contact with the printing plate I9. The upper bearing face of the dog IIII isin engagement with the bearing face 99 of the tripping lever 92, whereas that pair of form rollers l8 which cooperates'with the distributing roller I I is shown tripped from the plateIS, i. e. from the cylinder 26, and the dog I02 has assumed a position wherein its lower bearing face is in engagement with the bearing face I00 of thetrippinglever 93.
'The mode of setting the form rollers I8, and the manner ofoperation of the mechanism for tripping them will now be described.
Having reference to Figure 2, theform rollers I8' are first set for contact with their associated distributing rollers I6 and I'I,.by rotating the respective handles 54 etc. and therewith the associated eccentrics 52 etc. Then by means of the handles '41 the eccentrics 4| to 44 are rotated so that the form rollers are moved down and applied to theprinting plate l9. During such downward movement the rollers I8 move closer to each other by riding over the surface of their associated distributing rollers and by' remaining in contact therewith, the rollers I8 being guided during such movement by means of the links 48.
49 etc. r
The cam 90, which is mounted on ashaft I20, is assumed to rotate in a clockwise direction as indicated by the arrow in Figure 6. Furthermore 7 assuming for example that because of misregistration of a sheet fed to the printing press, the
conventional set up means herein referred to have been actuated as is well known by detector mechanism for the purpose of tripping the press track 9i where that pair of rollers I8 associated with the distributing roller II'have already been tripped i e. moved away from the plate I9, thereby interrupting the ink supply to the plate from these tWo form rollers.
The position'of the roller 94 in the track 9| I however,-is such that the form rollers I8 associated with the distributing rollers 16 are about to trip off the plate I9.
The tripping of all the form rollers I8 either away from the plate, or into contact with it, is
accomplished while said rollers pass over the gap v i I22 for strapping a printing plate to the form cylinder 20.
With the dog I02 in the position shown, the tripping lever 93 can continue its rocking motion rod 84- and linlr83.
- and :6.
.5 about" its: shaft 38 transmitted byrthe roller. 95
while following the track I1of cam 90,1,because the face 991 of: sai'dtl'ever, during: its downward movement, will clear thed'og" I02 and no further movement will be transmitted to that pair of rollers l8. It will also be noted that upon tripping of'the form. rollers. I8. from the. plate l9, contact with their: associated distributing rollers will be maintained.
During the, tripping-"action of the lever 93 and.
associated dog I02; the. link; I06 was moved'upwardly throught the intermediary of the connectingi rod. I.08.and' arm III, followingthe rocking movement oflshaft' 88 in an anti-clockwise direction, see- Figure. 6-, thereby depressing, the
connectingrod 86, rotating the; bellcrank lever 85. in an antieclockwise;direction. and. thereby'rotating the eccentrics 43 and. 44. due to theirconnection. with the;arm.85 by means of connecting These eccentrics will then be. all the way up thereby raising the arms 34 and 35 and trippingthe form rollers I8 from the plate I9, a position indicated both iii-Figures The tripping ofv these rollers occurred during; the passing of the gap I2I beneath them. 'I'hecam roller 94associated with tripping arm 92-. has assumed a position where the operating face 99 of said armis brought into operative engagement with the upper bearing face'of the'dog I0'I', so that during continued rotation of the cam 90 the dog is urged downwardly and the link I05- is rotating in a clockwise direction about the stud 91. This position of dog [0| having been transmitted to it through the intermediary of the connecting rod I I2, bell crank lever I I5, and connecting rod I I! which latter'a-s indicated herein' is associated with any conventional tripping or set up means.
Duringv this movement of the dog IOI, namely to the right as viewed in Figure 6, theconnecting rod I01 will be prlled down and the rock shaft 82 through the lever IIO secure-d thereto will be rocked in a clockwise direction.
This rocking motion of the shaft 82 is then transmitted through arm BI, connecting rod 80 and bell crank lever 18, connecting rod I6 and link to the eccentrics M and 42 which then will assume the position shown in Figure 5, and consequently that pair of form rollers I8 associated with the distributing roller I6, will trip away from the plate I9 while maintaining contact with the roller I6; This tripping also takes place during the passing of the gap I2I beneath said form rollers.
Upon re-setting the conventional automatic tripping and set up mechanism, the dogs IM and I02 will assume position opposite to those shown in Figure 6, so that upon rotation of'the cam 90 through the cam rollers 94 and 95, the operating face Ilia of the tripping lever 92 will be brought into association with the lower operating face of the dog IOI whereas the operating face 09. of the tripping lever 93 will engage the upper operating face of the dog I02, thereby the movement of the respective operating parts for the. eccentrics I 4|, 42', 43 and 44 will be actuated in a direction their;associated..trippingzleversz. 92 and...aa.unom
the" continued rotation of the: cam until through; some reason. or; other: the: automatic tripping. and setting .up. mechanism is again actuated.
It shall be understood that while I have described a preferred arrangement of parts. and operatingimechanism' therefor, many modifications thereof may be introduced without departing from the principle of my invention and therefore, I desire to cover'any such changes in the arrangement of" parts and their operating mechanism as will come within the scope andjmeaning of'the appended claims.
