Definitions

  • Reed Fisher Attorney-Seidel & Gonda ABSTRACT A printer-slotter used for printing and slotting carton blanks of double-faced corrugated board is provided with a gear train brake.
  • the gear train brake is used for preventing undesired rotation of the gears during certain operations,
  • This invention relates generally to printer-slotters for printing and slotting carton blanks which are usually of doublefaced corrugated board or the like. More particularly, this invention relates to a printer-slotter having a gear train brake to pennit selective restraining of a cylinder thereof during a die fitting, die or slotter head adjusting operation.
  • the cylinder may be a print cylinder, a die-cut cylinder or the slotter head cylinder.
  • each operation is performed in a module which may be removed from the machine for the fitting of attachments, cleaning, servicing, etc.
  • the modules are in position for operative transmission of power from a main drive motor in the feed end module succeeding modules, power is transmitted by means of intermeshing gears to each module. If the printing module, for example, isseparated from its adjacent modules, the power train gears are exposed and free to rotate.
  • the usual practice is for the operator to separate the printing module from the remaining modules of the printer-slotter so that the components thereof are readily accessible.
  • the printing die is then fastened to the print cylinder by means of staples, special clamps, adhesive, or other equivalent means.
  • the operator customarily rotates the print cylinder by energizing a compensator motor. That is, one edge of a die is secured to the print cylinder and then the compensator motor is operated or energized so as to cause the print cylinder to rotate through a portion of 360. In this manner, the die is wound onto the print cylinder.
  • the torque necessary to wind a heavy die onto a print cylinder may be enough to turn the other shafts in the module instead of turning the print cylinder, since the motor turns the print cylinder through a differential.
  • the gear train must be locked to insure the rotation of the print cylinder as well as to prevent the gear train from getting out of phase.
  • the print cylinder Since the die unbalances the print cylinder, the print cylinder will rotate as soon as power is removed by deenergizing the compensator motor. This balance of the print cylinder will cause rotation of the gears in the gear train bringing them out of phase so that they will not properly mesh when the modules are repositioned for operation of the print cylinder.
  • operators have prevented rotation of the gear train by jamming a wedge of wood or other material into the gears. This has not been a desirable practice because the wedge of wood is removed just before the modules are closed and the gears may still rotate to an out-of-phase position.
  • contamination of gear train lubrication oil by fragments of wood or other materials from the wedge.
  • FIG. 1 is a schematic side elevation view of a printer-slotter in accordance with the present invention.
  • FIG. 2 is a partial perspective view of modules of a printerslotter as illustrated in FIG. 1, illustrating the present invention.
  • Printer-slotter l0 includes the feeder unit A and a delivery unit B having therebetween a plurality of printing units I, II and Ill. Each of the printing units in identical. Hence, only printing unit II will be described in detail. Corresponding structure may be illustrated with prime numerals on the remaining printing units.
  • Each of the units is a module adapted to be moved along a track 12 so as to separate the modules for purposes of setup, installation, adjustment, repair, servicing, "etc.
  • Printing unit 11 includes side frames 14 and 16 which rotatively support a print cylinder 18 on shaft 20.
  • a printing die 22 is attached to the print cylinder 18 in any conventional'manner, such as by means of staples, special clamps, adhesive, etc.
  • the shaft 20 may be selectively rotated by means of a' compensator motor 24.
  • Motor 24 is coupled to shaft 20 by means 0 a drive mechanism designated generallyas 26.
  • the drive mechanism 26 is coupled to a ring gear 28 by means of planetary gears.
  • the ring gear 28 is coupled to gear 30 on shaft 32.
  • a print anvil 34 is provided on shaft 32 and cooperates with the print cylinder 18.
  • a plurality of feed rollers 36, and 38, 50 and 52 are provided for feeding the blanks to the print cylinder 18.
  • Feed roller 50 is mounted on shaft 54.
  • the ring gear 28 is mechanically coupled to the shafts for the feed rollers 36, 38, 50 and 52 by means of a gear train including gears 40, 42, 44, 46 and 48.
  • a brake designated generally as 56 is provided for selectively locking one of the shafts in a stationary position.
  • the shaft to be locked in a stationary position is shaft 54.
  • Shaft 54 is provided with an extension beyond the frame 14 for cooperation with the brake 56.
  • the brake 56 includes a lever arm 58 mounted for pivotable movement on a pin 60.
  • Pin 60 is parallel to shafi 54.
  • Lever 58 is biased to a brake positioned by means of a spring 62.
  • Spring 62 is a coil spring surrounding a rod 64 adjustably supported by a bracket on frame 14.
  • One end of the lever arm 58 is curved for contact with the brakeshoe on shaft 54.
  • the other end of lever am 58 is provided with an elongated slot 68 through which a rod 66 extends.
  • the upper end of rod 66 is provided with a limit stop such as an adjustable nut.
  • crank throw 70 The lower end of rod 66 is rotatably connected to one end of a crank throw 70.
  • the crank throw 70 is fixed secured to a shaft 72 extending transversely between the frames 14 and 16. Between the frames 14 and 16, crank throws 76 and 76' are fixedly secured to shaft 72.
  • Each of the crank throws 76 and 76' are connected by a crank shaft to latch pins 74 and 74, respectively.
  • Each of the pins 74 and 74 are adapted to cooperate with latch openings 80 and 80', respectively, on the adjacent module I. Rotation of shaft 72 through an arc of is manually attained by means of a lever or handle 78.
  • each of the printing units is provided with a latch operated by means of a lever or handle 78.
  • each handle 78 is vertically disposed and the latch pins 74,74 project into a latch opening on the next adjacent unit or module.
  • the handle 78 With the modules in an extended position, it is possible to release the brake by rotating the handle 78 through an arc of 90 for any desired purpose. Generally, the handle 78 will remain in its horizontal disposition when the modules are in an open disposition since this will maintain the desired relationship for the gears of the gear train between adjacent modules. It will be obvious to those skilled in the art that any equivalent power device may be utilized in place of the spring 66.
