Definitions

  • the time required to print a given design by known machine or methods was equal to the sum of the time it took to perform each of the necessary succeeding operation or series of steps, as for example, indexing the material by driving a belt on which the material is supported, positioning the screen and associated squeegee on the material, printing the material by moving either the squeegee or the screen during the printing stroke, raising the screen and squeegee off the material, returning the screen to start position, and repeating the indexing of the material again in readiness for the next repeat.
  • an object of this invention is to provide an improved method for screen printing repeating designs on continuous strips of material at a considerably faster rate than by the methods now known.
  • Another object is to provide a machine for automatically performing the improved method of this invention.
  • Still another object is to provide for improved means and manner of increasing the accuracy of the indexing and printing operation or step.
  • Still another object of this invention is to provide for the respective and opposite movement of the screen and squeegee relative to each other during the screen printing operation an amount sufiicient to assure that the squeegee overrides the stenciled area of the screen to provide the necessary overlap for accurate printing and positive indexing.
  • the method is preferably automatically carried out on a machine that includes an endless belt on which the vmaterial to be printed is supported, means for positively holding the belt and material thereon in its exact stopping position, a printing head including the screen reciprocally mounted for movement with the belt for indexing the same, means for moving the screen and associated squeegee vertically between printing and non-printing positions, means for gripping the printing head to the belt and materials,
  • a feature of this invention resides in the provision wherein the indexing and printing of the material are simultaneously performed and thereby eliminate a heretofore time consuming step or operation.
  • Another feature resides in the relative and opposite respective movements of the screen and its squeegee during the printing and indexing operation to assure for accurate alignment of each repeat, the relative movement of the squeegee and screen further reducing the time required to traverse the printing and indexing stroke.
  • Still another feature resides in the particular manner in which the belt is indirectly driven so as to assure elimination of stretch in both the belt and material supported thereon during printing and indexing of the material.
  • Another feature of this invention resides in the provision of a perforated belt utilized in conjunction with means for producing a vacuum as a means for firmly securing the belt and material in exact stopping position before and after printing and indexing operations; e.g. during the return of the printing head upon the completion of the printing and indexing stroke.
  • FIG. 1 is a side elevation view of the screen printing machine by which the improved method of this invention is automatically carried out.
  • FIG. 2 is a plan view of the machine of FIG. 1 but shown without the squeegee assembly.
  • FIG. 3 is an enlarged schematic side elevation view of the machine.
  • FIG. 4 is an enlarged detail view of one form of a belt gripping means.
  • FIG. 5 is an enlarged detail of the screen raising cam.
  • FIG. 6 is an enlarged detail plan view of the vacuum belt support table.

  • FIG. 12 is a side elevation view of FIG. 11.
  • the instant invention is directed to an improved method of screen printing repeating designs on a continuous strip of material and primarily a fabric material.
  • the method to be described may be equally applicable for the screen printing of paper, cardboard, metal, glass or plastic, either in a continuous web or in individual units.
  • repeating design is here-in meant to include the printing of a single continuous distinct design in succeeding sections; as Well as to the repeating of a given design several times on a continuous strip of material.
  • the improved method of this invention comprises the steps of continuously and successively taking a section of a sheet material from a source of continuous supply and placing the same on a movable or indexing belt.
  • the belt is perforated and is movably mounted to slide over a perforated table that is connected up to a suction or a pressure reducing device so that by evacuating 3 the air from beneath the belt and material the same may be held fast in its exact stopping position.
  • a printing head including a carriage containing a screen or a series of screens and associated Squeegees is placed over the material to be printed.
  • the material to be printed is held fast to the belt by evacuating the air to create a suction or vacuum under the belt as the printing head is positioned thereon.
  • the screen and associated squeegee are lowered onto the material into printing position.
  • the screen in printing position the belt and material are secured to the printing head.
  • the carriage, belt and material secured
  • the carriage including the screen, belt and material, is then driven as one in the direction of belt travel causing the screen to pass the squeegee a distance equal to the repeat of the design.
  • the relative movement of the screen past the squeegee causes the color to flow out of the leading well portion of the screen onto the material. In this manner the material is indexed at the same time that it is being printed, the belt and material being indirectly driven to minimize stretch.
  • an important aspect of the improved method is to provide for a slight movement'of the squeegee relative to the screen in a direction opposite to the movement of the screen or the direction of the belt travel an amount sufficient to permit the squeegee to override the printing or stenciled area of the screen.
  • the squeegee upon the termination of the printing and indexing stroke, will be disposed in the opposite or trailing well portion of the screen.
  • the degree of overlap afforded by this relative movement between squeegee and screen enhances the registration of the design to be printed with the previously printed design.
  • the forward end of the printing screen is gradually raised above the surface of the material as the printing carriage and the belt advance during the printing and indexing step so that at the end of the indexing step the screen is completely separated from the printed material.
  • the suction onthe belt is again applied to hold the indexing belt in its exact stopping position; and the gripping means securing the carriage to the belt released.
  • the squeegee is then raised off the screen and the screen raised to level position above the belt. With the screen and associated squeegee off the belt and material, the carriage including the screen is returned to initial start position in preparation to repeat the operation.
  • the machine comprises a frame or bed 21
  • the frame 21 is defined by corner upright leg members 22 interconnected by longitudinally and transversely extending structure tie member 23, 24 respectively.
  • rollers 25 and 2s mounted adjacent each end of the frame 21 are rollers 25 and 2s rotatably journaled in suitable bearings 27.
  • an endless belt having an upper flight 23A and lower flight 28B.
  • the belt sub-assembly 29 Connected to the frame or bed 21 and extending between rollers 25 and 26 is a belt sub-assembly 29. As shown in FIGS. 1, 11 and 12, the belt sub-assembly 29 comprises spaced parallel sides 30, each including spaced vertical supports 31 for supporting the sub-assembly 29 on upper longitudinal member 23 of the frame 21. Between the upright supports 31 extend a pair of spaced structural members 32, 33.
  • a plurality of spaced transversely extending cross-tie members 34 extend between the opposed sides 30 of the frame sub-assembly 29.
  • the upper longitudinal members 32 of the sub-assembly 29 consist of an angle member having its flange 32A turned inwardly.
  • Flange 32A disposed in a substantially horizontal plane, defines a rail on which the printing head 35 is free to slide or roll, as will be hereinafter described.
  • a table frame 36 Supported on the frame sub-assembly 29 and between sides 3t) of the sub-assembly 29 is a table frame 36.
  • the table frame 36 comprises simply rectangularly disposed structural members supported between the sides 36 of the frame sub-assembly 29.

  • the table top 37 and the belt 28 are each provided with a series of perforations or holes 4t), 44 respectively.
  • the table top 37 consists of a table member 38 having a surface 33A formed with a series of spaced transversely extending grooves 38B. Extended over the surface of the table member 3% is a covering sheet 39 to define a smooth fiat surface.
  • This covering sheet 39 may consist of a sheet of thermosetting plastic, e.g. Formica or the like.
  • Formed in the covering sheet 39 and in alignment with each of the transversely extending grooves 383 are a series of holes 40.
  • Each of holes 441: is thus in communication with their respective grooves 383.
  • Grooves 338 in turn are connected by a bore 41 in communication with a chamber 42 defined by a groove 42A formed in a block 42B connected to and extended transversely of the member 33 and in alignment with groove 383.
  • the chamber 42 defined by the groove 42A in block 4213, in turn, is connected to a suitable vacuum producing means or pressure reducing means 420 by a' suitable conduit 42;! connected to a hole 43 which forms an outlet for exhausting air from the chambers 38B and 42A.
  • the openings or perforations 4% formed in the table covering 39 are connected to the pressure reducing means 420, which, when energized, will draw or evacuate the air from channels 338 and 42. and thereby create a suction on the belt supported on top 39. This suction holds the belt fast.
  • the belt 28, arranged to be supported on the perforated tabe top 39, is likewise formed with a series of openings 44 therein which are arranged to register with some of the holes 40 in the table top.
  • the printing head 35 is reciprocally mounted on the frame sub-assembly 29.
  • the printing head includes a carriage having opposed side assemblies 35A interconnected by suitable cross-ties 358 to define a rectangular structure.
  • Each side assembly 35A includes corner posts 4-5 interconnected by longitudinal stringers 46 and 47.
  • Stringer 46 comprises an angle member having a leg portion 46A turned inwardly of the carriage so as to be disposed in a horizontal plane. Spaced below the stringer 46 is a second stringer 47 and it too is an angle member.
  • Stringer 47 has its leg or flange 47A turned inwardly and parallel to the flange 46A of stringer 46.

  • Fixed to the piston rod 48A of the respective piston and cylinder assembly 43 is a lon gitudinally extending plate 49 which is common to the piston rods 48A of each piston and cylinder assembly 48.
  • flange 46A of stringer 46 and the plate 49 connected to the piston assemblies 48 are disposed, respectively, above and below the marginal portion of the upper flight 28A of the belt 23.
  • flange 46A and plate 49 function as a mechanical grip for securing the carriage 35 to the belt 28 as will be hereinafter described.
  • the flange 45A of the opposed side members 35A constituted the fixed jaw of a mechanical gripper means.
  • the plate 4Q connected to the piston rods 48 form the movement jaw of the gripper means.
  • the movable jaw 49 is moved outwardly toward fixed flange 46A to clamp therebetween the belt 28.
  • a guide 56 connected to the ends of the movable jaw or plate 49 rides in an elongated slot 51 formed in the corner post 45 and serves to guide plate 49.
  • Rollers 52 rotatably journaled on suitable pins 53 connected to extend outwardly from each corner post 45 guide the carriage 35 for reciprocable movement along the rails 39 defined by the frame subassembly 29.
  • the inturned flange 46A occupies a marginal portion of the belt 28, and therefore decreases the useful area of the belt 23 by an amount equal to the sum of the areas of the respective fixed jaws 46A. Therefore, if it is preferred to utilize this portion of the belt, it will be understood that a vacuum type gripping means (not shown) may be substituted in lieu of the mechanical grippers described. Gripping the carriage 35 to the belt 28 by such vacuum gripper will function in the manner similar to that hereinbefore described with reference to the vacuum belt holding table top 37. With a vacuum gripping means, the entire surface area of the belt 28 is free to be utilized. Thus a larger printing area is afforcled by vacuum grippers without a resulting increase in the overall width of a given belt.
  • Each printing screen 55 therefore consists of a central stenciled portion which forms the area of design to be printed, and impervious areas or well portions disposed on either side of the stencil portion for containing the color to be forced through the screen.
  • the impervious or well portions overextend the printed area of the preceding printed design. For example, for a repeat of 72 inches the length of the screen may be 84 inches. This then provides for a 6 inch well on either side of the repeat.
  • Such silk screen constructions are well known, as exemplified by US Patents 2,545,277, 2,566,919. Therefore a more detailed description of such screen is not considered essential to an understanding of this invention.
  • each screen 55 is supported within the carriage 35 for vertical movement between operative printing position and inoperative non-printing position.

  • the squeegee 57 extends transversely of its respective screen 55 and each is connected to the piston rod 58 of a fluid actuated piston and cylinder 59 assembly.
  • the piston rod 53 on which the squeegees 57 are mounted in arranged to move the squeegees 57 relative to their respective screens 55 in a direction opposite to the travel of the belt during the printing stroke. For example, when the carriage 35, belt 28, and material move to the left as indicated by arrow 69, the squeegees 57 are moved slightly in the opposite direction.
  • the squeegees are also mounted for vertical movement between printing and non-printing position.
  • Piston and cylinder assemblies 51 function to raise and lower the squeegees and their actuating piston and cylinder assembly 59 between printing and non-printing positions.
