  • ANTI-SMUDGE SHEET TRANSFER DEVICE I Filed June 50, 1967 IIVIIIIIIIII INVENTOR BRUNO B PASQUINELLI ATTORNEYS United States Patent 3,442,506 ANTISMUDGE SHEET TRANSFER DEVICE Bruno B. Pasquinelli, Evergreen Park, Ill., assiguor to Miehle-Goss-Dexter, Incorporated, Chicago, 111., a corporation of Delaware Filed June 30, 1967, Ser. No. 650,339 Int. Cl. B65h 29/06 U.S. Cl. 27185 11 Claims ABSTRACT OF THE DISCLOSURE
  • the sheet transfer device is composed of arcuate sectors supported for rotation about an axis disposed transverse to the path of the sheets. The sectors are in spaced parallel relation and they are laterally adjustable relative to the sheet path and each sector has a plurality of sheet supporting members thereon which are selectively positionable in a radial direction to provide support for the sheets only in non-image areas thereof.
  • the invention pertains primarily to multicolor unit type printing presses. It is directed more specifically to the provision of improved means for transferring sheets between succeeding units of such presses whereby contact with the printed portions of these sheets may be completely avoided.
  • the present invention is directed to an improved sheet transfer device which obviates the disadvantages of the known systems. It essentially consists of a series of armate sectors which are mounted for lateral adjustment on a reduced diameter drum and each sector carries a series of selectively, radially positionable sheet engaging elements at spaced intervals about the periphery thereof.
  • the sectors and elements are conveniently adjustable and suitable gage means are provided on the sectors and on the drum, which makes it possible to make ready the respective members from a proof of the sheets to be printed.
  • the transfer device can therefore be made ready simultaneously with the respective printing units instead of after said units are made up, to thereby substantially reduce, if not completely eliminate, the extra make-ready time which has previously been required for this purpose.
  • Another object is to provide an improved sheet transfer device which incorporates suitable gage means whereby the sheet supporting elements can be made ready simultaneously with the printing units to thereby reduce, if not completely eliminate, the extra time previously required for this purpose.
  • FIGURE 1 is an elevational view as seen from the right of FIGURE 2 and showing a portion of a sheet transfer device constructed in accordance with this invention
  • FIGURE 2 is a sectional view in elevation, taken along line 2-2 of FIGURE 1;
  • FIGURE 3 is an enlarged sectional view taken along .line 3-3 of FIGURE 2;
  • FIGURE 4 is an enlarged sectional view taken along line 44 of FIGURE 1.
  • a preferred embodiment of the sheet transfer device is illustrated as including a main supporting shaft or drum 10, having a series of gripper fingers 11 and pads 12 mounted thereon and which are adapted to be actuated in a conventional manner so as to take succeeding sheets from the impression cylinder of one printing unit, convey them in a reverse curvilinear path as indicated by the broken line A in FIGURE 2, and then transfer them to the grippers on the next transfer drum or to the grippers on the impression cylinder of the next succeeding printing unit as is well known in the art.
  • FIGURE 1 Only a portion of the drum 10 is shown in FIGURE 1, but it will be understood that it extends across the full width of the press with the journals thereof mounted for rotation in the respective press side frames and that it is gear-driven in timed relation with the adjacent cylinders.
  • each sheet As each sheet is conveyed about the axis of the drum 10, the printed side thereof faces inwardly toward the drum, and to avoid contact between the wet, freshly printed image and the surface of the drum, the latter is formed with a substantially reduced radius and the body or trailing portion of each sheet is adapted to be supported at its normal radius by a series of reel type assemblies, indicated in their entirety by the numeral 13.
  • a series of these assemblies obviously will be arranged at spaced intervals along the drum to provide support for the sheet over its entire width, but since they are all identical, only one such assembly will be described in detail and similar reference numbers will be used to designate corresponding elements in the other assemblies.
  • the drum has two fiat areas 14 formed at diametrically opposite points on its periphery which provide a base for two bars 15 that are secured to the drum, parallel to its axis, by means such as the bolts 16.
  • the bars 15 are coextensive with the drum and they are adapted to support one or more brackets 17, each of which carries an arcuate section 18 having a series of sheet engaging elements 19 thereon for supporting the sheets.
  • the brackets 17 are formed with channels 21 and 22 adapted to slidably fit over the flanges 23 and 24, respectively, on the bars 15 and the brackets are arranged to be individually adjustable longitudinally along the bars by means of a pinion gear 26 carried by the bracket and which is adapted to mesh with rack teeth 27 formed along the top edge of the flange 23.
  • a pinion gear 26 carried by the bracket and which is adapted to mesh with rack teeth 27 formed along the top edge of the flange 23.
  • One end of the pinion gear extends beyond the bracket and is provided with a hexagonal head 28 to accommodate a wrench for adjustment purposes and it is secured against axial movement in the bracket by a retainer 29 which fits into the neck 30 in the gear and is fastened to the bracket by a bolt 31. Accordingly, each bracket 17 and its associated assembly is individually adjustable along the drum 10 and its location can readily be determined by means of a calibrated scale 32 attached to the bar 15 and which is coextensive therewith.
  • Each bracket 17 also carries locking means in the form of a bolt 33 and a clamp member 34 for securing it against unintended movement along the bar 15 once its position has been established.
  • the bolt 33 is inserted through an opening in the bracket and is threaded into the clamp member 34, which is located in a recess pro vided on the opposite side of the bracket,
  • the clamp member has a lip 35 formed thereon adapted to engage the side face of the flange 24 so that when the bolt 33 is tightened, the lip 35 is pressed tightly against the flange 24 to secure the bracket in its adjusted position.
  • the bolt is loosened, the clamping effect is relaxed and the bracket is released for adjustment purposes.
  • each bracket is adapted to carry a sector 18, which may be secured to either side face 36 or 37 of the bracket by bolts 38 in a manner that it is concentric with the drum 10.
  • the sector essentially consists of a body portion 39 having a laterally projecting flange 41 and a series of uniformly spaced, radially disposed holes 42 are formed in said flange 41 to accommodate a corresponding number of sheet engaging elements 19.
  • a groove 43 is formed in the peripheral surface 44 of the sector in alignment with the holes 42 and a flange 45 of slightly greater radius than the surface 44 is formed along one side of said groove for a purpose which will become evident hereinafter.
  • Each of the sheet engaging elements 19 is formed from round wire stock which is bent into a substantially U-shaped configuration, with one arm 46 thereof being substantially longer than the other arm 47.
  • the long arm is inserted through a hole 42 in the flange 41 and it is retained therein by a compression spring 48, which is con- .4 fined between the flange and a cup washer 49 that is held on the arm 46 by a pin 51.
  • the spring 48 thus exerts a constant force on the sheet engaging element in a direction toward the axis of the drum 10 and it serves to retain said element in either its operative or inoperative position.
  • the element In the operative position, the element is turned so that the end of the short arm 47 thereof is seated in the groove 43 on the flange 41. In this location it maintains the element in a radially projected position wherein the outermost point of the element is coincident with the sheet path and will thereby support the sheet during its transfer.
  • the inoperative position the element is turned approximately 90 degrees, at which point the short arm 47 is aligned with and is adapted to be received in a recess 52 provided in the surface 44 of the sector adjacent to each hole 42, as indicated by the broken lines in FIGURE 3.
  • the recess thus permits the element to be retracted well within the radius of the sheet path under the influence of the spring 48 to thereby avoid contact with a printed portion of the sheet.
  • the spring 48 is designed in such a manner that it not only exerts a constant biasing force to maintain the elements in the respective operative and inoperative positions, but it also acts as a positive stop to lirnt the radial outward movement of the element.
  • the spring when an element is manually moved radially outwardly for setting in the operative position, the spring will be fully compressed when the end of the arm 47 thereof clears the surface 44 of the sector. The element can then be pivoted to and from the operative position. However, when fully extended, the end of the arm 47 will not clear the projecting flange 45 on the sector 18, which thus serves to limit the pivoting movement of the element and thereby facilitates setting the respective elements in the operative position.
  • the sheet engaging elements are consecutively numbered by indicia, which may be stamped or otherwise applied to the sector adjacent each hole 42 and which indicia bears a direct relation to the distance of each element from the gripper pads 12. Accordingly, when the assembly is to be made ready, it is a simple matter for the pressman to determine which of the elements should be placed in the inoperative position in order to avoid contact with the printed areas of the sheet.
  • the transfer device represents a relatively flexible means for transferring printed sheets without smudging and which is simple and convenient to make-ready. From a proof of the job to be printed, the pressman can readily determine the lateral positions of the unprinted tracks on the sheets between the images, and by means of the callbrated scale 32 on the bars 15, it is a simple matter to set the assemblies 13 so as to coincide therewith. Also, where the unprinted tracks are interrupted by interlocking image areas, the distance thereof from the leading edge of the sheet can be measured, and by means of the indicia on the sectors, the sheet engaging elements which coincide with such image portions can be readily identified and set in their inoperative position. These settings can readily be made while the printing units are being prepared for another job so that the press will be ready to print as soon as make-ready of the printing units is completed.
  • the assemblies 13 on each side of the drum 10 are constructed as completely independent units which are separately adjustable along the drum. This arrangement is preferred because it provides additional flexibility whereby the respective assemblies can be offset relative to one another to compensate for small offsets in the unprinted tracks in the sheets which seldom are continuous throughout the length of the sheets.
  • the two sectors 18 could be replaced by a single sector, which would be supported as a single unit comprising two brackets 17. In such case, however, only one bracket would be provided with a pinion gear for adjustment puposes and the other bracket would simply slide therewith on its supporting bar 15.
  • a sheet transfer device for transferring sheets between units of a printing press comprising a rotatable drum, gripper means on said drum for engaging the leading edge of a sheet and conveying it in a reverse curvilinear path having a radius greater than that of said drum from a cylinder of one unit to the next adjacent cylinder whereby the wet, freshly prinled side of the sheet faces inwardly toward the drum, an arcuate sector, a series of aligned sheet engaging elements mounted at spaced intervals about the periphery of said sector, said elements being selectively positionable between an inoperative position wherein they are withdrawn from the sheet path and an operative position wherein they are coincident with the sheet path, means including an elongated member extending parallel to the axis of the drum for mounting said sector for rotation withsaid drum, and adjustable means including a rotatable member associated with said sector for adjusting the sector along said elongated member longitudinally of said drum.
  • the moutning means for the arcuate sector includes a bar mounted on said drum and extending across the path of the sheets, a bracket moutned on said bar, said sector being mounted on said bracket, and additionally including means for adjusting said bracket laterally along said bar.
  • a sheet transfer device as set forth in claim 6, wherein the adjusting means for said bracket includes a rack formed along one edge of said bar, a coacting pinion rotatably mounted in said bracket, and means for rotating said pinion to thereby adjust said bracket along said bar.
