Definitions

  • the present invention relates to magnetic means for moving a squeegee in a screen printing apparatus.
  • the squeegees for spreading the printing paste over the screens having therein the patterns to be printed are carried on a reciprocable carriage above the screens, and the squeegees are suspended from these carriages.
  • Many types of devices have been suggested for insuring that the pressure of the squeegees on the screens is uniform across the entire width of the screen, thus insuring that the paste is spread evenly and that the printing of the pattern on the cloth is accurate and even. All of these devices, however, operate to exert pressure on the squeegee from overhead, i.e. through the carriage from which the squeegee is suspended. It is not easy to control such pressure when it is exerted from above against the screen, and it is not easy to insure that the pressure is uniform all along the length of the squeegee.
  • a squeegee of magnetic material and providing a magnet beneath each'screen, cloth and supporting belt which extends across the entire width of the screen and magnetically attracts the squeegee with a uniform attractive force so that the squeegee exerts uniform pressure on the screen at all points along its length.
  • the magnet is movable back and forth so that as it moves it causes the squeegee on top of the screen to move with it.
  • FG. 1 is a perspective view, partly cut away, showing the portion of the screen printing machine in which the screens and squeegees are positioned;
  • FIG. 2 is a sectional elevation view talren along line 2 2 of FIG. 1.
  • An endless belt 1 is driven over two rollers (not shown) and the top run of the belt serves as a support for the cloth 3 which is to be printed.
  • the edges of the top run of the belt 1 are guided along the bottom edges of guides 2 mounted on the side frames 15 of the apparatus.
  • frame holders 4 Secured to lifting rods 12 along the top edges of the guides 2 are frame holders 4 which extend across the run of the belt 1 and which also extend downwardly toward the surface of the belt 1.
  • a frame 5 Secured between the frame holders i of each pair is a frame 5 which has stretched over the bottom thereof a screen 6 with a pattern cut therein which is to be printed on the cloth 3. The pattern is indicated in the drawing by the dotted line exentding around the screen.
  • each screen 6 On each screen 6 is a squeegee, which in the apparatus according to the present invention is a cylindrical rod 7 having a small diameter, for example 0.5 cm.
  • the squeegee is movable back and forth across the screen 6, and as it moves it pushes a mass of paste ink d ahead of it to spread it over the screen, and at the same spread the paste through the openings forming the pattern in the screen and onto the cloth to be printed.
  • the squeegee 6 is movable in a direction parallel to the direction of the run of the belt 1, but it is also possible to have the squeegee run in the direction transverse to the belt.
  • Beneath the upper run of the endless belt 1 are a plurality of groups of beams, one group for each frame 5.
  • Each group of beams includes at least two supporting beams 10 spaced from each other in the direction of the run of the belt 1, and a magnettic beam 9 which lies between the supporting beams 11i.
  • the supporting beams 10 support the belt in the vicinity of the frames 5 s0 that the cloth 3 is kept substantially iiat.
  • the magnetic beam 9 has magnet means therein which in the present embodiment is comprised of electromagnets 16 extending along the length of the beam.
  • a nut 1&1 secured to the bottom of the beam
  • a nut 9a also secured to the bottom of the beam.
  • Extending through all of the nuts on one side of the upper run of the belt 1 is a threaded spindle 11, and a similar spindle extends through the nuts on the other side of the belt.
  • the spindles 11 are driven by the driving means for the belt (not shown) so that the movement of the beams 9 and itl are synchronized with the movement of the belt as described hereinafter.
  • the cloth 3 to be printed is secured to the belt 1 in a conventional manner and the belt 1 with the cloth secured thereto is fed into one end of the machine by means not shown.
  • the edges of the belt run along the guides 2 and the central portion or" the belt is supported by the supporting beams 1b.
  • the driving means for the belt move the belt step by step, each step being a movement for a distance equal to the dimension of a frame holder 4 plus the distance between frame holders, so that the area of the cloth which is beneath one frame holder d at the end of one step is moved to a position under the next frame holder d in the next step.
  • the lifting rods 12 are lowered so as to lower the frame holders i mounted thereon, and a quantity of printing paste is placed along the rod '7, either by an automatic dispensing means known to those in the art, or manually.
  • the spindles 11 are driven in a direction to move the supporting beams 1@ and the magnetic beam 9 along the bottom of the belt from a position below one edge of the frame holder 4 to a position below the other edge or the frame holder.
  • the rod 7 Since the rod '7 is of magnetic material, and since the magnetic beam 9 will attract the rod 7, the rod 7 will be moved along over the screen 6 on the bottom of the frame holder 4 so as to spread the paste S through the pattern in the screen onto the cloth.
  • the paste When the rod '7 approaches the edge of the frame holder 4, the paste will start to pile up and will flow over the rod 7, so that when the rod reaches the end of its movement adjacent the edge of the frame holder 4, the paste which remains after spreading has flowed over the rod and is ahead of the rod when the reverse movement of the rod takes place.
  • the lifting rods l2 are then lifted, lifting the 'frame holders and the screens 6 from the cloth, and the belt driving means again moves the cloth ⁇ forward another step. Thereupon, the entire process is repeated.
