6 SPECIFICA TIONS 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).
7 SPECIFICA TIONS RIBtype PRINTING DIES FIGURE 4 ® Universal Non-Porous Coders are designed to use Universal RIBtype rubber type, printing dies which have a molded rib backing. The ribs on the back of the die snap into mating ribs in the RIBtype Drum Cover on the print drum as shown in Figure 4.
8 SPECIFICA TIONS 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.
9 QUICK ST AR T INST ALLING THE INKING SYSTEM ASSEMBL Y Y our new Non-Porous Conveyor Line Printer was fully assembled and adjusted at the factory before final inspec- tion.
10 QUICK ST ART 2 - Loosen the Knurled Pivot Arm Knob “C” & swing the Inking System Assembly “A” away from Print Drum. INST ALLING THE PRE-INKED ROLL 5 - Press the Inking System Assembly t.
11 QUICK ST AR T 6 -Carefully pull the Inking System Cover “L” directly away from the Inking System Baseplate “M”. Do not let the cover drag across the surface of the T ransfer Roller “N”. 3 -While holding the Knurled Drive Wheel Cover “J” in place, remove the Knurled Cover Retaining Knob “K” by turning it counter-clockwise.
12 QUICK ST ART 10 - Immediately replace the Inking System Cover “L” by carefully guiding the cover over the T ransfer Roll “N”. T ry not to let the cover cont act the surface of the T rans- fer Roll to prevent scratching. Make sure the Cover is seated properly against Baseplate “M”.
13 QUICK ST AR T 13 - Replace the Knurled Cover Retaining Knob “K” and lightly tighten. Do not over tighten this knob or you may bend the top of the Knurled Drive Wheel Cover “J” and cause it to bind against the Knurled Drive Wheel. Now retighten the Pivot Arm Knurled Knob.
14 QUICK ST ART 2 - When using the smaller individual characters to make up a code message, use the T ype Blocking Kit “Q” in- cluded with your coder to support the leading and trail- ing ends of the type as shown.
15 QUICK ST AR T FOR MOUNTING INSTRUCTIONS REFER TO THE APPROPRIA TE SECTION FOR YOUR APPLICA TION WEB PRINTING - P AGE 19 CARTON PRINTING - P AGE 23 ADJUSTING THE INK ROLL ECCENTRIC As soon as you can see complete ink coverage on the die faces, stop rotating the eccentric.
16 BASIC PRINCIPLES OF OPERA TION Note: The MT Ink Roll is disposable by design and is not to be used with the 4 oz. ink cartridge. When the ink is depleted from the MT Ink rolls they are to be discarded.
17 BASIC PRINCIPLES OF OPERA TION It is also extremely important to test the affect of other manufacturer ’s ink on the XF Neoprene ink roll. Since the ink roll must fit into a precision machined ca.
18 BASIC PRINCIPLES OF OPERA TION When the coder is installed on a Form and Fill machine, the plastic film may move at fairly high speed when pulled from the supply roll but it stops for a period of time during the product fill cycle.
19 WEB PRINTING T o eliminate this problem, if idler roller positions are not adjustable, a slight undercut in the face of idler roller “B” where the printed marks pass under the roll, will prevent the wet marks from touching the face of the idler .
20 WEB PRINTING 3 -Press down lightly on the spring tension arm to compress the tension spring slightly . (Fig- ure 35) While holding a light pressure on the arm, tighten the mounting bracket clamping screw . Note: This procedure is used to adjust the contact pressure which the print drum exerts against the web.
21 WEB PRINTING Universal Non-Porous Conveyor Line Printers can also be mounted on custom designed extension arms which will enable them to print directly on the surface of a master roll of web material as it is unwound. This technique is fre- quently used when conveniently positioned idler rolls are not available.
22 WEB PRINTING 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.
23 CART ON PRINTING Universal Non-Porous Conveyor Line Printers are spring loaded so that the print drums will press against the carton surface on contact. This pressure is necessary to accomplish the friction drive rotation of the print drum and ensure enough printing pressure to give you a sharp impression.
24 CART ON PRINTING Before tightening the mounting bolts, check alignment of the print drum. It is very important for proper tracking that the top of the print drum is parallel to the top of the conveyor (Figure 41) and the side of the print drum is parallel to the side of the carton (Figure 42).
25 CART ON PRINTING Figure 45 illustrates the best die position for carton printing when using extremely fast drying inks. Note that the leading edge of the printing die should be positioned rotationally upstream of the transfer roll. When the leading edge of the carton contacts the print drum, the drum begins to rotate in a clockwise direction.
26 CARTON PRINTING If the cycle rate of the production line is very fast and the ambient temperature is relatively low , the printing dies could be positioned rotationally downstream of the transfer roll so they print much closer to the leading edge of the carton.
27 MAINTENANCE 3 - Inspect the roll to ensure it is completely saturated with ink but not dripping wet. If the surface of the roll seems excessively wet after inking, remove the excess ink by in- serting a rod through the core and while pressing down lightly , roll the roller across a clean piece of paper .
28 MAINTENANCE 1 - Periodically , the inking system should be disas- sembled and inspected for ink residue and dust con- t amination. T o remove ink cont amination from the surface of the machine, moisten a soft cotton cloth with the appropriate ink solvent and rub it across the contaminated area.
29 MAINTENANCE 3 - Blot the surface of the die with a clean paper towel to dry as shown in and reinst all the clean dies on the coder . 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.
30 MAINTENANCE 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.
31 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. 3- Remove the Adjusting Bolt and replace it on the opposite side of the T ension Arm.
32 MAINTENANCE 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- T o relieve the spring tension on the index mechanism, ro- tate the Print Drum approximately 3/4 turn.
33 7- Retighten the Brass Tipped Set Screw to lock the Index Ring in position. This screw must be tight to prevent the Index Ring from rotating under spring tension.
34 MAINTENANCE 8- Reinstall the Index Ramp in the proper orientation for your mounting configuration as shown in Figures 64 & 65. 1- T o replace Print Drum Index Springs, rotate the Print Drum approximately 3/4 turn to relieve spring tension as shown in Figure 59, Page 32.
35 MAINTENANCE REMOVING AND REPLACING INDEX BLOCK “B” 1- T o remove Index Block “B” from the Print Drum, roll down the RIBtype Drum Cover directly behind the Index Block to expose the Index Assembly Mounting Screw.
36 MAINTENANCE 4- While holding Index Block “B” in this position, tighten the Index Assembly Mounting Screw by turning it counterclock- wise until tight. FIGURE 73 FIGURE 71 3- When replacing Index Block “B” it is very important to align the top surface of the Index Block with the top surface of the Index Ring as shown in Figure 72.
37 MAINTENANCE INKING SYSTEM ASSEMBL Y 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.
38 When adequate pressure is applied to the Eccentric Knob dur- ing assembly , the knob should have a moderate resistance to turning. When assembled properly , the ink roller axle should be feel rigid. MAINTENANCE 5 - Install the Eccentric Knurled Knob and align the engraved line on the knob with the “MAX” line on the Inking System Cover .
