" In'Great Britain March 2, 1932 I 11 Claims- (CL 101162) This invention relates to relief printing machines wherein dies or engraved plates are used in conjunction with means for effecting the required pressure for printing and embossing in relief.
Hitherto printing and embossing in relief has been generally done in presses wherein the impression is obtained by a rising and falling plunger, operated by means adapted to produce the required pressure, and presses or machines of the aforesaid kind have necessarily been of heavy and massive construction in order to eifect'the required pressure which is simultaneously distributed over the whole surface of the die plate.
The object of the present invention is to provide an improved construction and arrangement of relief printing machine which is lighter in construction than the usual type of presses hitherto used and is therefore less costly to produce, and is also adapted to provide for increased speed of production.
' According to the present invention we provide a machine for printing .and embossing in relief, characterized by the provision and use of a vertical or upwardly inclined reciprocating die bed on which is mounted a die plate, operating in conjunction with a rotatable force cylinder adapted to give the impression and arranged to carry the sheet of paper to be printed and embossed over the face of the die plate during the reciprocating movement of the die bedin one direction, whereby a line pressure is made between the reciprocating die plate and the rotary force cylinder commencing-at one end of the die plate and gradually extending to the other end thereof. 3
The invention also consists in the provision of means for inking and wiping the die plate dur-' ing its reciprocating movement.
The invention further consists in the provision of means whereby the force cylinder is held and prevented from rotating during the reciprocating movement of the die bed when the die plate is being inked and wiped, and in means whereby an'initial rotary movement is imparted to the force cylinder at the commencement of the movement of the die bed, which eifects the printing and embossing operation.
The invention also consists inthe provision of er material from a continuous roll is intermittently and adjustably fed over a wiper plate and moved into contact with the reciprocating die plate, the said means including mechanism for regulating the amount of wiping paper used in each operation.
The invention further consists in the provision of check mechanism whereby the rotary force cylinder can be prevented from rotation and held in a position clear of the die plate during the" reciprocating movement of the latter whenfor any reason it is desired to temporarily discontinue ieedingsheets into the machine.
The invention further consists in the provision of mechanism arranged to operate in conjunction with the check mechanism, and adapted to make inoperative the inking and the drawing through of the wiping paper, when the check mechanism is put into operation for preventing rotation of the force cylinder.
In the accompanying drawings, Figures 1, 2, and 3 are respectively a side elevation, a front view, andan'opposite side elevation of a relief printing machine, constructed in accordance with and embodying the features of this invention.
Figure 4 is a diagrammatic view, on an enlarged scale,- ofthe mechanism adapted to impart an initial turning movement to the rotary force cylinder.
Figure 5 is a diagrammatic view, on an enlarged scale, of the wiping plate and the mechanisms for adjusting and actuating same.
Figure 6 is a sectional view taken on a plane extending centrally and longitudinally through the force cylinder of the machine.
Figure '7 is a sectional view taken on a plane extending centrally and transversely through the force cylinder.
According to one practical embodiment as illustrated in the drawings, we provide a die bed 1 which is slidably mounted'in vertical or upwardly inclined guides 2 fixed to the side members of the frame, and is adapted to have mounted thereon a fiat die plate 3. The said die bed'l has fitted at. the front and'near the sides thereof toothed racks 4 arranged to engage with pinions 5 on the ends of a cylinder 6 mounted on a shaft which is car,- ried, in the side members of the frame, the said cylinder 6 having adjust'ably mounted thereon a segmental pressure or force plate105, and gripper mechanism '7 for engagement with the sheets to be printed and embossed. The adjustment of the force plate 105 on the cylinder 6 in one convenient arrangement, as seen in Figures 6 and '7, is effectedby a longitudinally slidable wedge 106, mounted in grooves 107 formed on the cylinder 6 and arranged to engage with a correspondingly inclined face on the underside of the force plate 105. Longitudinal movement is imparted to the said wedge 106 by means of pinion 108 engaging with a rack 109 fixed to the wedge 106. The pinion 108 is adapted to be rotated by a worm 110 'on a shaft 111, which is rotatably mounted in the fixed shaft of the cylinder 6 in which it is longitudinally confined by a fixed collar 112. The shaft 111 is provided with a hand wheel 113 for the rotation of same to effect the radial adjustment of the force plate for the purpose of building up and maintaining the required pressure between the force plate and the reciprocating die plate 3. The force plate 105 is mounted upon the cylinder 6 by means of bolts 114 provided with springs 115 adapted to draw the force plate to its inward position. The outer face of the force plate 105 isin known manner built up with one or more layers of millboard 116 and an outer layer of force cloth 117. On the rear side of the'reciprocating die bed or slide 1 are mounted toothed racks 8, preferably two, arranged to engage with toothed pinions 9 fixed to a shaft 10 and adapted to have imparted thereto a reciprocating movement, the said pinions 9 being further arranged to engage with toothed racks 11 fixed on or between the side members of the frame, whereby the reciprocating movement of the said shaft 10 through the pinions 9 is adapted to impart a reciprocating movement to the die bed or slide 1, which is equal to twice that of the said shaft 10, the reciprocating movement of the aforesaid shaft 10 being obtained in one convenient arrangementby means of a connecting rod 12 between the shaft 10 and a crank pin 13 mounted on apinion 14 fixed to a countershaft 15 and driven from a main or driving shaft 16. On the reciprocating shaft 10 is mounted a roller 17 arranged to engage with a guide plate 18 and adapted to prevent undesired pressure of the pinion 9 in its engagement with the toothed rack 8 on the reciprocating die bed or slide 1.
In order to balance the reciprocating die bed or slide 1 we may employ balance weights 19 which are connected thereto by a chain or belt 20 carried over pinions or pulleys 21 mounted in the side members of the frame.
Between the side members of the frame and in alignment with the force cylinder 6 is mounted a transverse block or frame 22- which is adapted to support the reciprocating die bed or slide 1 and withstand the forces imparted thereto in its travel between the said block and the force cylinder in the operation of printing and embossing, and in order to reduce friction between the said members,
we provide any suitable form of anti-friction device which in one form may comprise vertical ribs 23 formed on the face of the fixed block 22 arranged to engage with anti-friction rollers. or bearings 24 interposed between. the said ribs and suitable faces formed on the rear part of the reciprocating die bed or slide 1. a
In the toothed pinions 5 of the force cylinder 6 which engage with the racks 1 on the reciprocating die bed or slide 1 is formed a'clearance or cut-away part 25 which is arranged to permit of the racks moving upward without imparting rotary movement to the force cylinder 6, and mechanism is provided whereby an initial turning movement is imparted to the force cylinder to bring the teeth of its pinions 5 into engagement with those of the racks i on the reciprocating die bed or slide 1 when the latter commences its downward movement, the said mechanism in one convenient arrangement, as seen in Figures 1 and 4, comprising an operating lever 26 having at its upper end a suitably shaped gap 27 which is engaged by a projection 28 on the force cylinder 6 when the latter has been moved through nearly a complete revolution in the downward travel of the die bed or slide 1, the said operating lever 26 being connected at its lower end to one arm of a bellcrank lever 29 whose other end is provided with a cam bowl 3O engaging a cam mounted on the countershaft 15, the said cam being adapted to impart movement tothe operating lever 26, whereby an initial rotary movement is imparted to the force cylinder 6 which is arranged to bring .the teeth of its pinions 5 beyond the gap or clearance formed thereon, into engagement with the rack teeth 4 on the die bed or slide 1, at the commencement of the downward movement of the latter.
As seen on reference to Figure 4, when the force cylinder 6 is at rest during the upward movement of the die bed 1 and its racks 4, the cam bowl 30 moves over the dwell or face a of its cam, during which period the gapped end 2'7 of the operating-lever 26 is in engagement with.
the projection 28 on the force cylinder 6. When the die bed 1 commences its downward movement, the cam bowl 30 passes over the peak I) of the'cam, and an upward movement is imparted to the operating lever 26 to the position shown in dotted lines, whereby an initial rotary movementis imparted to the force cylinder 6, bringing the teeth of its pinions 5 into engagement with the toothed racks 4 on the reciprocating die bed 1, and as the cam bowl 30 rides down the face 0 of the cam, during the continued movement of the racks 4 and rotary movement of the force cylinder 6, the operating lever 26 moves to its lower position, as shown in dotted lines, with its gapped part 27 ready for engagement with the projection 28, and as the cam bowl 30 rises up the cam to the dwell part a thereon, the operating lever 26 is again moved to the position shown in full lines, where it remains while the rotary force cylinder is at ,rest during the upward movement of the reciprocating die bed 1.
suitable known arrangement, and, as seen in Figure 1, in connection therewith we provide a composition roller 31 carried on a pivoted rocking arm 32 and adapted to be oscillated so as to move the said roller from its contact with the main inking roller 33 into contact with the die plate 3 during the downward reciprocating movement of the dierbed or slide 1 when it is near the end of its downward travel, the said oscillating movement being effected by a bell-crank lever 34 connected by a rod 35 with a bell-crank lever 36 provided with a cam bowl 37 arranged to engage with a cam 38 onthe countershaft 15,
the said cam being formed with a depression which provides, through the lever and link mech- Illanism, a forward movement of the inking roller appropriate part of its downward travel.
part of the upwardreciprooating movement of meases the die plate byarrangingan appropriate dwell of the cam bowl37 on the cam38, The wiping of the-die plate -3 after inking-,ito
remove the ink from the plain face ;thereof,-is e1 fected by means of a slightly curved wiping plate- 39 over which the wiping-paperis carried, the said wiping plate39 being arranged to have impartedthereto a combined rocking androlling-motion and is adapted to continuously bringa fresh face. of the wiping paper intocontact with the upward 1y moving die plate 3,;- In one ;con-venient arrangement the wiping plate 39, as seeninFig-ures l, 3, and 5, is adjustably supported in the verticalposition by a rod or bar-40 which is connected at its lower end to one arm of a bell-crank lever 41 pivoted to the side member of the machine, the
other arm of the saidbellecrankleverbeing engaged by a screw threaded shaft 42.;WhlChQiS rotatably mounted on the side-member of the machine and provided witha hand wheel;-43-the,ro--
tation of which-is adapted-to impart a raising or lowering movement to the wiping plate 3 9 ;in order to adjust its positionin relation to -the-recipro-- cating die plate?) to suit various sizes or disposi tions of die plates. -The combined rocking and rolling motion-of the wiping plate 39 in one convenient arrangement; as seen in Figure 3, is effected by a cam 44 on the countershaft l5 engag-- ingwith a cam bowl on one arm of a pivoted bellthe bell-crank lever; 47 through the medium of a compressionspring, which, while resisting the forces transmitted through the said lever mechanism, is also adapted to permit of the adjustment of the wiping mechanisms: g
In order to adjust the position of the face of the wiping plate 39 in relation to that of the die plate 3, and consequently, adjust, or vary the pressure between the said members, we provide in con junction with inclined bearers 53 fixed to the side members of the frame, adjustable taper. wedges,
54 on which are fitted pegs 55 whichiprotrude through slots in the side members of the frame and engage with pivoted arms 56-having formed therein a radial slot 57 engaged by a clamping bolt 58 and provided with la handleor knob 59.. In order to adjust the wedges .54the clamping bolt 58 is first slackened, when by means of the-han dle or knob 59 the arms 56 engaging with the pegs 55 can be readily moved toraise or lower the Wedges 54, which constituteabearing for the urved bearing faces 39a formedon the-ends of the wiping plate 39, thereby moving the latter slightly inward or outward in relation to there-i ciprocating die plate 3.
The wiping web or paper 60 which is-in the form of a. continuous roll .61 carried on a trans-,
verse shaft62 is arranged, as seen Figure 1, to pass over a feed roller 63 mounted-on a transverse shaft carried in bearings inthe side mom-- a bers of the frame, and it is then passed over the face of the wiping plate-39, theusedpaper being guided over'a transverse rol1er 64 and thence onto a winding drum:65. I
An intermittent feed movement is'imparted .to
the wiping paper 60, asseen in Figuresij, by means of'the bell-crank lever 66 provided on one arm with a cam bowl arranged to engage, with the cam 44, iwhich as previously described is also adapted to impart a'rocking movement to the wiping plate 39, the other arm of the said bell+ crank lever 66'being connected by a rod 67 with ratchet clutch mechanism on a spindle or shaft 68, on which is also mounted an intermediate gear wheel 69 which engages with gearwheels mounted on the shafts carrying the feed roller 63 and the winding drum 65. The winding drum is connected to its shaft by a friction clutch or like slipping device to permit of a partial free rota-- tion of'the said shaft without rotation of thewinding-drum 65, such independent free movement being adaptedto vary in accordance with the'increasing diameter of the roll of used paper;
wound on the said drum. In order to prevent slip and ensure that the feed roller 63 draws the required amount of wiping paper from-the roll 61, a pressure roller 70 carried on pivoted arms '71 and controlled by springs 72 is adapted to hold the wiping paper in frictional contact with the feedroller- 63, as seen in Figures 2 and 3.
, In order to vary or regulate the amount of Wiping paper used in each cycle of operation of the machine according to the size of any particular dieplate in use; meansare provided for limiting the movement of the rod 67 which, as
before described, is adapted to impart -intermittentniovement tothe shaft 68, on which is mounted the gear wheel-69 engaging with they gearwheels onthe shaft of the feedroller 63. and the winding roller 65, the said means, as
seen in Figure 3, comprising an adjustable plate 73 freely carried on a transverse shaft 74 rotatably mounted on theside member of the machine, the inclined upper face -of. the said plate '73 being arranged to engage with a roller 75 on the joint pin which connects the said rod -to the cam operated bell-crank lever 66'. On thesaid shaft 74 is also freely carried an adjustinglever 76. provided at its pivot-end with alugorpr-o jection77 arranged to engage with a lugor projection on the adjustingplate 73, so that by a turning movement of the lever 76 about the shaft 74.;will vary the disposition -of the upper in clined. face of the adjustable plate 73 in relationto the roller 75 on the end of the reciprocatingrodfi'l, thus varying or controlling the down-,
wardmovement of the said rod, and consequently varying or controlling the'movement imparted to the ratchet feed mechanism on the shaft68. The adjusting lever 76 has formed therein a radial slot engaged'bya clamping pin 78 mounted-in the side member of the machine, and adapted to fix the said lever in any desired position;
,In order .to ensure that the backward rotary movement of the force cylinder 6 is arrested when the cut-away part of the teeth of the pinions 5 on .theflends thereof reaches the position in front and out .of engagement with the'rack teeth 4 on the reciprocating die bed or slide 1, a spring cone; trol catch 79 engages with and forms an abut-z ment forthe lug or projection 80 on the end of 4 theforce-cylinder 6, as seen in Figures 1 and 4, in which position the forward movement is restrained by engagement of "the gapped "611121 of the operating lever 26 withthe projection 28.
In order to remove and recover some of the ink removed by the wiping paper '60 from the die; plate 3, a; scraper device 101', as seen in Figures:
2 and 3, is arranged to impinge against the wipingpaper as it passes over. the roller 64 after being drawnover the wiping plate 39, the said.
scraper device being located directly above the inking trough and the main inking roller 33, as seen in Figure l, the ink removed by the scraper falling on to the said inking roller and back to the trough.
Check mechanism is provided for preventing rotation of the force cylinder 6 when the cut-- away part of its pinions 5 aligns with and is clear of the racks 4 on the reciprocating die bed or slide 1, as for instance when it is desired to run the machine for making ready the inking of the die plate and adjustment of the wiping paper; also check mechanism is provided whereby the inking mechanism and the wiping paper feed can be made inoperative, as for instance when it is desired to run the machine while making ready the face of the force cylinder 6 and adjusting or regulating the pressure thereof on the die plate 3 in the reciprocating die bed or slide 1.
In the arrangement illustrated the check mechanism for the force cylinder 6 is brought into operation by the pedal 81, as seen in Figures 1 and 2, and the mechanism for checking the inking and the wiping paper is operated by the pedal 82, as seen in Figures 2 and 3. The spring controlled pedal 83, as seen in Figures 2 and 3, is adapted to simultaneously operate each of the check mechanisms previously described.
In a preferred arrangement the check mechanisms, as seen in Figure 3, comprise a lever 84 pivoted to the side member of the'frame and provided near its middle with a roller 85 engaging with a cam (not shown) on the countershaft 15, the said lever having at its lower end a notched part 86 which is adapted to engage with either or both of a pair of forks 87 which are normally held clear of engagement with the said lever 84 by lugs or projections on pivoted weighted levers 88 connected by links 89 with the pedals 81 and 82. Upon depressing the pedal 81 a turning movement is imparted to one of the weightedlevers 88, and the lug or projection on the upper end thereof is turned so as to permit of a lowering movement on one of the forks 87, thus permitting it to engage with the notched end of the cam operated lever 84, and when the latter is moved outward by its roller 85 engaging withthe peak of the cam, rotary movement is imparted to a tubular.
sleeve 90 rotatably mounted on the shaft 74 by means of an arm 91 fixed on the said sleeve and hinged to the outer end of the said fork 8'7, as seen in Figures 2 and 3. On the said sleeve 90, as seen in dotted lines in Figure 1, is mounted an arm 92 connected by a rod 93 with a pivoted catch or lever 94. which when raised engages with the lug 80 on the rotary force cylinder 6 and checks its rotation, while simultaneously an arm or lever 95 connected to the outer end of the catch or lever 94, and engaging at its outer end with the rod or lever 26, causes the latter to move outward, moving its gapped end 2'? clear of engagement with the projection 28 on the rotary force cylinder 6, thus permitting of the continued up and down movement of the said rod or lever 26 during the running of the machine, while the force cylinder is checked. Upon'depressing the pedal 82 the other weighted lever 88 is turned and permits of the other fork 87 being lowered into a position for engagement with the notch 86in the cam operated lever 84 in a manner similar to that before described, and the said fork is connected to an arm 96, as seen in dotted lines in Figure 3. the said arm being fixed to the shaft 74 to which a part rotary movement is imparted by the cam operated lever S it-through the approp'riate'fork neeasos;
37. .Ontheouter end of the shaft 74 is fixed a boss 9'7 provided with-alug arranged to engage with a lug ontheadjustable plate 73, whereby the latter is turned to bringthe notch 98 formed in its periphery under the'roller75 on the end of the rod 67,thus holding the cam bowl on the end of-the cam operated bell-crank lever 66 clear of engagement with itscam, and thereby prevent movement to the rod 6'7, thus checking the feed mechanism of the wipingpaper, while simultane-' ously the inking mechanism is checked by a weighted lever 99 fixed to the shaft '74, as seen in Figure 1, the said lever being provided with a projection 100 which -moves into engagement with-a roller 102 on the end of the cam operated bell-crank lever 36, thereby holding the said lever clear of engagement with its cam and thus checking the inking mechanism. The spring controlled pedal 83 through lever and link mechanism is adapted, when depressed, to permit both the forks 87 tobe lowered into engagement with the notched end of the cam operated lever 84, whereby the check mechanism for the rotary force cylinder and that for the inking and the feed of the wiping paper are brought into operation.
In the process of making ready for printing, one or more layers of the millboard 116 are fixed to the outer face of the force plate 105 and the latter is gradually forced outward by the adjusting mechanism into contact with'the reciprocating die plateB, thereby causing the face of the millboard to'be pressed into the engraved parts of the die plate, thus producing a raised impression on the millboard corresponding to the engraved or recessed parts of the die plate, and finally the layer of force cloth 117, which may be American oil cloth or the like, is fixed thereto and the operation of making ready as above is continued, and when finished the segmental face of themake-up on theforce plate 105 corresponds to the pitch line of the pinions 5 on the force cylinder 6.
The operation of the machine is as follows:- We will first assume that the machine has been run and that the die plate 3 which is inked and wiped ready for printing and embossing is at the upward end of its reciprocating movement, as shown in the drawings, and is about to commence its downward movement, and a sheet has been fed up to suitable lays in position for engagement withthe grippers '7 on the force cylinder 6, and the toothed pinions 5 of the latter have just moved into engagement with the racks 4 on the reciprocating die bed or slide 1. Immediately before commencement of the rotating movement of the force cylinder 6 the grippers 7 are arranged to engage the sheet. In the downward movement of the diev plate 3 the sheet is drawn between the latter and the force plate 105, which is adjustably mounted on the force cylinder 6, so that a line contact is made between the die plate and the'force'cylinder commencing at the lower part of the die plate 3 and gradually extending to its upper part. During the continued downward movement of the die bed or slide 1, after printing and embossing the sheet, the inking roller 31 is arranged to contact with the face of the die plate 3, and wiping is subsequently effected on the upward movement of the die plate. When the die bed or slide 1 has reached the end of its downward reciprocating movement, the force cylinder 6 has been rotated nearly one complete revolution, bringing its stud or projection 28 into engagement with the slot or gap 27 in the operating lever 26 which is adapted to effect the next initial operating with said die plate, means for rotat- 709: and means for intermittently drawing said wiping starting movement, and the gap or cut-away part in the toothed'pinionsS on the force cylinder 6 assumes a position clear of the racks 4. At'this stage the printed sheet is released from the grippers '7 on the force cylinder 6 and may be picked up by suction or other suitable means on to the endswof delivery arms 104 adapted to be rocked by-suitable lever and link mechanism actuated by a crank on the countershaft 15, the delivery arms being arranged to carry and drop the printed sheet on to endless delivery tapes 103 from which they are collected and placed onto trays for drying in the usual manner employed in connection with relief printing.
In the upward reciprocating movement of the die plate 3 the force cylinder 6 remains at rest until the die'bed or slide 1 reaches the upward end of its travel and commences its downward movement, when the operating arm or lever 26 imparts an initial movement to the force cylinder 6 which brings its toothed pinions 5 into engagement with the racks 4 on the reciprocating die bed or slide 1, and the operation as before described is repeated. In relief printing a slow drying varnish ink is used on a non-absorbent paper, and great pressure is applied to the paper in its travel over the face of the moving die plate by the adjustable pressure plate 105 of the force cylinder 6.
