  • Page 3: Preface

    Printing on non-porous materials has always been a major problem in industrial applications. The high degree of maintenance required to keep conventional coders operating with solvent based inks has made many compa- nies opt for manual marking as a cost effective alternative. With UNIVERSAL Non-Porous Coders, printing on non-porous materials can be accomplished with the same relative ease as printing on porous materials.

  • Page 6: Indexing And Non-Indexing Models

    INDEXING AND NON-INDEXING MODELS Universal Non-Porous Conveyor Line Printers are available in both indexing and non-indexing models. Indexing coders contain a print drum spring return mechanism which provides print registration capabilities when carton printing (see Figure 1). As the trailing edge of a carton passes the coder, the print drum automatically rotates back to the same starting or “home”...

  • Page 7: Printing Dies

    Universal Non-Porous Coders are designed to use Universal RIBtype® printing dies which have a molded rib backing. The ribs on the back of the die snap into mating ribs in the Drum Cover on the print drum as shown in Figure 4. The standard printing dies are available in sets with many sizes and character styles.

  • Page 8: Ink Rolls

    SPECIFICATIONS INK ROLLS Universal offers two ink roll options for the Non-Porous Conveyor Line Printers each with unique characteristics which will help determine the suitability for a specific printing application. The coders are designed to accommo- date both types of ink rolls without modification. A detailed review of your printing requirements will determine the best choice of ink rolls for your particular application.

  • Page 9: Quick Start

    INSTALLING THE INKING SYSTEM ASSEMBLY Your new Non-Porous Conveyor Line Printer was fully assembled and adjusted at the factory before final inspec- tion. In order to minimize the size of the shipping cartons used to package these machines, the Non-Porous Inking System Assembly was removed from the Pivot Arm and must be reinstalled before operation.

  • Page 10: Installing The Pre-Inked Roll

    5 - Press the Inking System Assembly towards the Print Drum and adjust the Position Adjusting Screw “F” until the Knurled Drive Wheel “G” makes positive contact with the Friction Bearer “H” on the Print Drum. When the Pivot Arm Adjustment Knob “C” is tightened, the Knurled Drive Wheel should only contact the Friction Bearer Ring with enough pressure to drive positively when the print drum is rotated.
  • Page 11 3 -While holding the Knurled Drive Wheel Cover “J” in place, re- move the Knurled Cover Retaining Knob “K” by turning it counter- clockwise. The Cover Retaining Knob holds the entire inking system together and other parts may fall free from the coder if not held securely when this knob is removed.
  • Page 12 7 -Put on a pair of rubber gloves and remove the pre-inked ink roller from the storage container by inserting a small rod (a pencil works nicely) in the center of the core. Keeping ink off your gloves at this stage will prevent contamina- tion of the external parts of the coder during roll installation.
  • Page 13 11 -Replace the Knurled Drive Wheel “G” by aligning the 3 small holes with the 3 stainless drive pins on the top of the Transfer Roll “N” and pressing the Drive Wheel onto the Transfer Roll. The tops of the stainless pins will be flush with the top of the Drive Wheel when seated properly.

  • Page 14: Installing The Printing Dies

    1 - Align the ribbed backing on the Printing Dies “P” with the mating drum covering on the Print Drum “D” and press firmly until they are completely engaged. It is best to install the dies as close to the middle of the print area on the Print Drum as possible.

  • Page 15: Adjusting The Ink Roll Eccentric

    ADJUSTING THE INK ROLL ECCENTRIC 1 - After the printing dies are installed on the print drum, manu- ally rotate the print drum continuously in one direction while slowly rotating the Ink Roll Eccentric Adjusting Knob “I” from the “MIN” position towards the “MAX” position. Turn the Eccentric Knob in small increments and observe the face of the Printing Dies “P”...

  • Page 16: Basic Principles Of Operation

    BASIC PRINCIPLES OF OPERATION Inks designed for printing on non-porous surfaces contain very fast drying alcohol solvents, a component to impart color which can be either a liquid “dye” or a finely ground solid or “pigment”, and a resin material which binds the color medium to the material surface.

  • Page 17: Selecting An Appropriate Ink

    BASIC PRINCIPLES OF OPERATION When a Reservoir Ink Cartridge is threaded into the bottle port, the plastic ball in the cartridge comes into contact with the surface of the neoprene ink roll. When the ink roll rotates during the printing operation, a thin film of ink is transferred from the reservoir cartridge onto the surface of the ink roll.

  • Page 18: Ink Drying Time Considerations

    BASIC PRINCIPLES OF OPERATION INK DRYING TIME CONSIDERATIONS Depending on the specific characteristics of the printing application, some consideration needs to be given to the drying time of the ink and its suitability for the application. Printing on a plastic film in an intermittent motion Form and Fill Machine may require a slower drying ink formulation than that recommended for high speed continuous web printing applications.

  • Page 19: Web Printing

    This section applies to the installation of the Non-Porous Conveyor Line Printers for printing on continuous web materials such as plastic films, rubber sheeting, metals and other extruded materials. Careful consideration should be given to selecting an appropriate area in the production line for installation of the coder.

  • Page 20: Web Printing Mounting The Coder

    In high speed web applications, the distance the web travels at a given speed in 2-3 seconds can be substantial. It is important to note that when the printed web is tightly rewound, the additional pressure applied to the printed marks can increase the possibility of a ghost image transfer of the ink to the back of the web.

  • Page 21: Special Web Printing Applications

    DO NOT INSTALL A 4 oz. RESERVOIR INK CARTRIDGE AT THIS TIME. The coder is designed to print using the ink contained in the pre-inked ink roll. Since a freshly saturated Ink Roll was just installed on the coder, the system will have plenty of ink.

  • Page 22: Gang Mounting

    In web printing applications where multiple coders are required to be mounted across the web, Universal offers special mounting hardware which facilitates gang mounting the coders as indicated in Figure 38. In these instal- lations, special CLP-SBA Saddle Mount Bracket Assemblies are used in conjunction with an extruded structural aluminum mounting bridge.

  • Page 23: Carton Printing

    CARTON PRINTING Printing on non-porous surfaces, such as waxed or varnished cartons, can be accomplished easily with Univer- sal Non-Porous Conveyor Line Printers. The selection of an appropriate place for installation on your conveyor line or other packaging equipment is a very important consideration in the performance of your coder. The most important factor to consider is carton alignment.
  • Page 24 CARTON PRINTING Universal Non-Porous Conveyor Line Printers are designed so the frame of the machine will pivot on the mount- ing column. This allows the print drum to deflect, or swing, on contact with the leading edge of the carton a maximum of 2".

  • Page 25: Die Positioning For Indexing Applications

    Loosen the mounting column clamping bolt (Figure 43) and position the printer to the required height for printing. Swing the printer into position so that the print drum will lightly contact the side of the cartons as they emerge from between the guide rails. Check the print drum contact with the cartons while the conveyor is under power and adjust the print drum position to obtain approximately 1/4"...
  • Page 26 CARTON PRINTING Although installing the printing dies in this position restricts how close to the leading edge of the carton you can register the print, it is one of the only ways to ensure a good imprint on every carton. Since the fastest drying non- porous inks will dry in approximately 2 seconds at 75 Degree F.

  • Page 27: Maintenance Pre-Inking A New Ink Roll

    When you are ready to begin printing, you must first install an ink roll which has been properly pre-inked with the appropriate non-porous ink. Unless you ordered a pre-inked roll with your machine, you will find a dry roll in a plastic container with your coder.

  • Page 28: Cleaning The Transfer Roll

    The surface of the transfer roll is made from DuPont Delrin material and the O.D. of the roll is finely engraved which enables it to hold a uniform film of ink. This surface material is very fragile and under no circumstances should you attempt to clean it with anything abrasive.

  • Page 29: Cleaning The Printing Dies

    All inks which are formulated for printing on non-porous surfaces contain a resin binder which bonds the dye or pigment in the ink to the surface of the material being printed. As the ink begins to dry, this binder becomes “tacky”...

  • Page 30: Mounting Configuration Conversion

    MOUNTING CONFIGURATION CONVERSION LEFTHAND / RIGHTHAND FIELD CONVERSION Mounting configuration conversion involves the “mirror image” reversal of the pivot arm assembly that holds the inking system and the tension arm assembly which provides the printing pressure. Indexing printers require the additional reversal of the index ramp and repositioning of the index ring.
  • Page 31 10 -Reinstall the Inking System Assembly and adjust as explained on Page 9 - Installing the Inking System Assembly. TENSION ARM ASSEMBLY CONVERSION 1- Loosen the Lock Nut and screw the Adjusting Bolt in to relieve the spring pressure (Figure 56). 2- Remove the spring by lifting the end off the Locating Button.
  • Page 32 PRINT DRUM INDEX MECHANISM CONVERSION 1- Using a 5/64” hex wrench, loosen the Nylon Tip Set Screw located in the top rim of the Print Drum. 2- Remove the Print Drum Dust Cover. 3- To relieve the spring tension on the index mechanism, ro- tate the Print Drum approximately 3/4 turn.
  • Page 33 5- Using a 1/8" hex wrench, loosen the Brass Tipped Set Screw located in the side of the Index Ring until the Index Ring rotates freely. PRINT DRUM AXLE RECESS AREA FIGURE 62 6- Rotate the Index Ring in a clockwise direction until it stops turning. Next, turn the Index Ring in the counterclockwise direction as necessary until the Brass Tip Set Screw is pointing directly at the Transfer Roll Axle as shown in Figure 63.

  • Page 34: Replace Print Drun Index Springs

    8- Reinstall the Index Ramp in the proper orientation for your mounting configuration as shown in Figures 64 & 65. RIGHT HAND CONFIGURATION FIGURE 64 REPLACING PRINT DRUM INDEX SPRINGS 1- To replace Print Drum Index Springs, rotate the Print Drum approximately 3/4 turn to relieve spring tension as shown in Figure 59, Page 32.

  • Page 35: Removing And Replacing Index Block "B

    4- Holding onto the Index Assembly Block “A”, pull the Index Assembly Block “C” off the guide shafts (Figure 68). Remove the Drum Index Springs (Figure 69) FIGURE 68 5- Install new Index Springs over the stainless steel guide shafts and replace Index Block “C”. Ensure that Block “C”...
  • Page 36 2- Lift Index Block “B” straight up to remove. The head of the Index Assembly Mounting Screw engages the T- Slot in Index Block “B”. This mounting design facilitates height adjustment of the Index Block during reassembly. Before replacing Index Block “B”, ensure that the Index Ring is properly adjusted as explained in Steps 5 - 7 on Page 33.

  • Page 37: Inking System Assembly

    The following steps will guide you through the Ink Roll Eccentric Assembly. 1 - Install the O-Ring in the groove of the Eccentric flange, then install one of the white delrin washers on the Eccen- tric. 2 - Apply a thin coating of grease to the O-Ring and the Ec- centric to approximately 1/2”...
  • Page 38 5 - Install the Eccentric Knurled Knob and align the engraved line on the knob with the “MAX” line on the Inking System Cover. Set the ink roller axle on a small block of wood or metal . The block used should be tall enough so the entire assembly is supported by the ink roller axle (the Inking Sys- tem Cover should not touch the table top).
