MAIN ASSEMBLY

amyr

11/15/2004


MAIN FRAME STARTER SWITCH: THE STARTER SWITCH IS MOUNTED ON THE OPERATOR SIDE OF THE MACHINE. IT INCORPORATES A

CIRCUIT BREAKER WHICH IS SET TO TRIP AT THE PROPER RATING OF THE MOTOR. TO REPLACE THIS SWITCH, FIRST DISCONNECT THE MACHINE FROM THE ELECTRICAL SUPPLY. REMOVE THE SWITCH BY LOOSENING THE TWO FASTENING SCREWS AND PULL THE SWITCH FROM THE ELECTRICAL BOX. REMOVE THE WIRES, NOTING THEIR CONNECTIONS TO THE SWITCH. TO REPLACE THE STARTER SWITCH, REVERSE THE PRECEDING PROCEDURE.

SIDE BELT DRIVE SYSTEM:

THIS SYSTEM CENTERS AND DRIVES THE BOX THROUGH THE MACHINE. THE BOX WIDTH IS SET MANUALLY BY TURNING THE HANDWHEEL LOCATED ON THE OPERATOR SIDE OF THE MACHINE. TO SET THEM, PLACE THE DESIRED BOX ON THE MACHINE BETWEEN THE BELTS, TURN THE HANDWHEEL CLOCKWISE UNTIL IT IS JUST TOUCHING THE BOX SIDES. IF THE BOX FAILS TO DRIVE, TIGHTEN THE BELTS SLIGHTLY. DO NOT OVERTIGHTEN THE SIDE BELT DRIVE AS THEY WILL PUT UNNECESSARY STRAIN ON THE DRIVE MOTORS. EACH BELT IS POWERED BY A MOTOR LOCATED AT THE EXIT END OF THE MACHINE. TO REPLACE THE BELTS, POWER OFF THE MACHINE AND REMOVE TWO SCREWS ON IDLER ROLLER. REMOVE BELT GUARD. SLIDE IDLER ROLLER TOWARD EXIT END OF MACHINE AND REMOVE BELT. THREAD NEW BELT ON DRIVE ROLLER, PLASTIC ROLLERS AND IDLER ROLLER - BE SURE THE “V” OF THE BELT SITS IN GROOVES OF ALL ROLLERS. ADJUST TENSION ON BELT BY SLIDING IDLER ROLLER TOWARD INFEED END OF MACHINE. REPLACE BELT GUARD, REPLACE TWO SCREWS IN IDLER ROLLER SHAFT. EACH BELT IS REPLACED SEPARATELY, HOWEVER, IT IS ADVISABLE TO REPLACE BOTH BELTS AT THE SAME TIME. DRIVE MOTOR: THE BELTS ARE DRIVEN BY TWO DRIVE MOTORS LOCATED AT THE EXIT END OF THE MACHINE. THE MOTORS ARE CONTROLLED BY THE STARTER SWITCH IN WHICH THE OVERLOAD IS FACTORY SET TO TRIP AT THE PROPER SETTING. IF TROUBLE IS BEING EXPERIENCED WITH A DRIVE MOTOR, A QUALIFIED ELECTRICIAN SHOULD CHECK THE ELECTRICAL SYSTEM. THE STARTER SWITCH SHOULD BE CHECKED FIRST. TO REPLACE A DRIVE MOTOR, FIRST DISCONNECT THE MACHINE FROM ELECTRICAL SUPPLY. REMOVE THE MOTOR GEARHEAD FROM MOUNTING PLATE. REPLACE WITH NEW MOTOR USING THE WIRING DIAGRAM IN THE MOTOR JUNCTION BOX. CHECK MOTOR FOR PROPER ROTATION. CHAINING:

TO INCREASE OR DECREASE THE TENSION OF THE CHAIN, LOOSEN CHAIN TIGHTENING SCREW ON REAR OF MACHINE (LOCATED NEXT TO THE MAST). SLIDE IDLER EITHER UP (TO DECREASE) OR DOWN (TO INCREASE), UNTIL THE DESIRED TENSION HAS BEEN REACHED, TIGHTEN SCREW. IF THE CHAIN NEEDS TO BE REPLACED, FIRST LOOSEN CHAIN TIGHTENING SCREW AND SLIDE IDLER UP TO RELIEVE TENSION. REMOVE CHAIN FROM SPROCKETS AND IDLER. THREAD NEW CHAIN OVER SPROCKETS AND IDLER. ADJUST TENSION ON CHAIN BY SLIDING IDLER UP/DOWN IN SLOT UNTIL THE DESIRED TENSION HAD BEEN REACHED, TIGHTEN CHAIN SCREW.


HEAD THE HEAD RIDES ALONG THE MAST ON BEARINGS AND HIGH DENSITY POLYETHYLENE PADS. THE HEIGHT OF THE HEAD IS ADJUSTED BY LOOSENING THE HEAD CLAMPING KNOB. TURNING THE CLAMPING KNOB CLOCKWISE WILL LOCK THE HEAD IN THIS POSITION. BEARINGS: IF ANY OF THE BEARINGS WHICH RUN AGAINST THE MAST NEED TO BE REPLACED, PROCEED AS FOLLOWS: - DISCONNECT ELECTRICAL SUPPLY. PLACE A STURDY BOX OR BLOCK ON BED OF MACHINE AND LOWER HEAD ONTO IT. - REMOVE COVER FROM BACK OF HEAD TO EXPOSE BEARINGS. LOOSEN OUTSIDE NUTS ON THREADED SHAFT. - BACK OFF NUTS BETWEEN BEARINGS WHILE TURNING THREADED SHAFT WITH A SCREWDRIVER UNTIL DEFECTIVE BEARING CAN BE REMOVED. - REVERSE ABOVE PROCEDURE TO REPLACE BEARING. - THE FRONT BEARINGS ARE ACCESSIBLE AND CAN BE REMOVED THROUGH THE BOTTOM OF THE HEAD. WHENEVER THE BEARINGS HAVE BEEN CHANGED, THE CLEARANCE BETWEEN THE HEAD AND THE MAST MUST BE RE-ADJUSTED. THE CLEARANCE BETWEEN THE TEFLON SLIDES AND THE SIDES OF THE MAST SHOULD BE ADJUSTED TO APPROXIMATELY .020” (.5 mm). THIS SHOULD BE CHECKED THROUGH THE HEADS’ RANGE OF TRAVEL TO INSURE THAT THIS CLEARANCE EXISTS AT THE HIGH POINTS OF THE MAST. THE CLEARANCE BETWEEN THE BEARINGS AND THE FRONT AND REAR SURFACES OF THE MAST SHOULD BE SUCH THAT THE HEAD MOVES FREELY AND DOES NOT COCK OR SAG. TO ADJUST THE CLEARANCE, PROCEED AS FOLLOWS: - REMOVE COVER FROM REAR OF HEAD. - ADJUST CLEARANCE OF TEFLON SLIDES FROM SIDES OF MAST BY LOOSENING LEFT NUT ON THREADED SHAFT LOCATED ON THE OUTSIDE OF HEAD, AND TIGHTEN NUT LOCATED AGAINST INSIDE OF ROLLER A CORRESPONDING AMOUNT. THIS HAS THE EFFECT OF SPREADING OPEN THE SIDES OF THE HEAD. ADJUST THE FRONT AND REAR THREADED SHAFTS TOGETHER TO KEEP THE TEFLON SLIDES PARALLEL TO THE MAST. FIRST ADJUST THE UPPER PAIR OF SHAFTS THEN THE LOWER PAIR. - MOVE HEAD THROUGH ITS FULL TRAVEL AND CHECK THAT TEFLON SLIDES HAVE PROPER CLEARANCE AT THE HIGH POINTS.


TAPE CARTRIDGE TAPE CORE: THE ROLL OF TAPE IS RETAINED ON THE TAPE CORE BY TWO SPRINGS PRESSING AGAINST THE INSIDE OF

THE TAPE ROLL. TO ADJUST THE DRAG ON THE TAPE CORE, TURN THE ADJUSTMENT NUT. TURNING THE ADJUSTMENT NUT CLOCKWISE OR COUNTERCLOCKWISE WILL INCREASE OR DECREASE THE DRAG. THIS ADJUSTMENT SHOULD ALWAYS BE THE MINIMUM NECESSARY TO PREVENT THE TAPE FROM OVERRUNNING. TOO MUCH DRAG, ESPECIALLY WITH STRETCHY TAPE, MAY RESULT IN POOR TAPING, BAD CUTOFFS, TAPE SNAPBACKS, OR JAMS. THE WIDTH ADJUSTMENT SCREW IS USED TO CENTER THE TAPE. THIS IS THE SLOTTED SCREW LOCATED IN THE CENTER OF THE TAPE CORE. WIPE DOWN ROLLERS:

THE RUBBER WIPE DOWN ROLLERS WIPE DOWN THE TAPE AS THE BOX PASSES THROUGH THE MACHINE. THE

PRESSURE EXERTED BY THE ROLLER IS ADJUSTABLE BY CHANGING THE POSITION OF THE MAIN SPRING TO ANOTHER HOLE LOCATION ON THE CARTRIDGE TIE BAR. THE PRESSURE SHOULD BE NO MORE THAN NECESSARY TO OBTAIN A GOOD WIPE. IT SHOULD BE REDUCED FOR BOXES WITH COMPRESSIBLE CONTENTS IF THE FLAPS ARE BEING DEPRESSED EXCESSIVELY DURING WIPING.

KNIFE:

THE KNIFE IS NORMALLY SELF-CLEANING. IF IT SHOULD ACCUMULATE A DEPOSIT OF ADHESIVE, IT MAY BE CLEANED WITH AN OILY RAG. BE CAREFUL WHEN HANDLING THE KNIFE IT IS VERY SHARP.

WHEN THE KNIFE BECOMES DULL, IT SHOULD BE REPLACED OR RESHARPENED. WHEN REPLACING THE KNIFE, MOUNT THE KNIFE SO THAT THE CENTER HOLE MATCHES THE CENTER PIN ON THE KNIFE ARM. THEN FASTEN THE CLAMPING PLATE WITH THE (2) M5 X 8 FASTENING SCREWS. RESHARPEN THE KNIFE BY LIGHTLY GRINDING ACROSS THE BACK OF THE TEETH REMOVING ABOUT .010” (.3 mm) OF MATERIAL. THIS SHOULD BE DONE ONLY WITH A SURFACE GRINDER. DO NOT GRIND BELOW THE

BASE OF THE TEETH. BE CAREFUL NOT TO OVERHEAT THE KNIFE SINCE IT IS HEAT TREATED. THE KNIFE ARM SHOULD PROJECT 1 ¾” TO 1 7/8” (44 mm TO 48 mm) BELOW THE BOX LINE. THIS DIMENSION MAY BE ADJUSTED BY TURNING THE KNIFE STOP. GUIDE PLATE: THE TAPE IS GUIDED TO THE FRONT ROLLER BY THE GUIDE PLATE. THE FLAT PORTION OF THE GUIDE PLATE MUST BE TANGENT TO THE ROLLER FOR PROPER OPERATION. THIS IS ADJUSTABLE BY ROTATING THE ECCENTRIC STOP IS AN OFF-CENTER SPACER FASTENED WITH A HEX SCREW.


TAPE CARTRIDGE CONT. FINGER PLATE: THE FINGER PLATE PRESSES AGAINST THE ADHESIVE SIDE OF THE TAPE AND FORCES THE TAPE TO TAKE THE SHAPE OF THE GUIDE PLATE FOR STIFFENING. IT IS IMPORTANT THAT THE FINGERS JUST MAKE CONTACT WITH THE GUIDE PLATE WHEN THERE IS NO TAPE. IF THE GUIDE PLATE IS PUSHED BACK, THE FINGER PLATE SHOULD MOVE. IF AN ADJUSTMENT IS NECESSARY, GENTLY BEND THE FINGERS NEAR POINTS. ONLY BEND A SMALL AMOUNT AT A TIME AND CHECK THE RESULT BEFORE MAKING A FURTHER ADJUSTMENT. THE TOP AND BOTTOM TAPE CARTRIDGES ARE IDENTICAL AND MAY BE INTERCHANGED. BOTH CARTRIDGES ARE REMOVABLE FROM THE MACHINE BUT ONLY THE LOWER CARTRIDGE MUST BE REMOVED TO LOAD TAPE. THE TOP CARTRIDGE MAY REMAIN IN PLACE WHEN LOADING TAPE. REMOVING BOTTOM CARTRIDGE: - RAISE HEAD TO ITS UPPER POSITION. - STANDING AT THE CONTROL SIDE OF MACHINE, GRASP CARTRIDGE AT POINTS “A” AND “B”. - LIFT CARTRIDGE CLEAR OF MACHINE RAISING LEFT END (POINT “A”) SLIGHTLY HIGHER THAN RIGHT END. REPLACING BOTTOM CARTRIDGE: - GRASP CARTRIDGE AT POINTS “A” AND “B” WITH TAPE ROLL DOWN AND LOWER IT INTO PLACE WITH RIGHT END (POINT “B”) SLIGHTLY LOWER THAN LEFT END. REMOVING TOP CARTRIDGE: - RAISE HEAD TO ITS UPPER POSITION. - STANDING AT THE CONTROL SIDE OF THE MACHINE, RELEASE THE DETENT PLATE ON HEAD WITH LEFT HAND, AND WITH RIGHT HAND SLIDE CARTRIDGE TO THE RIGHT AS FAR AS IT WILL GO WHILE PRESSING UPWARD AT POINT “B” WITH RIGHT HAND. - WHILE STILL SUPPORTING CARTRIDGE WITH RIGHT HAND, TRANSFER LEFT HAND TO POINT “A”. LOWER CARTRIDGE BY DROPPING RIGHT END (POINT “B”) SLIGHTLY LOWER THAN LEFT END UNTIL CARTRIDGE IS CLEAR OF HEAD. REPLACING TOP CARTRIDGE: - GRASP CARTRIDGE AT POINTS “A” AND “B” WITH TAPE ROLL UP. - WITH LEFT END HIGHER THAN RIGHT, RAISE CARTRIDGE UNTIL IT IS SEATED. - SLIDE CARTRIDGE AS FAR TO THE LEFT AS IT WILL GO. CHECK THAT DETENT PLATE HAS ENGAGED IN THE SLOT IN CARTRIDGE FRAME.


TAPE CARTRIDGE CONT. BOTTOM CARTRIDGE MUST BE REMOVED BEFORE PERFORMING THE FOLLOWING TASKS. INITIAL LOADING OF TAPE: - PUSH TAPE ROLL ONTO TAPE CORE WITH TAPE FEEDING COUNTERCLOCKWISE. TAPE ROLL SHOULD BE PUSHED TO THE BACK OF THE TAPE CORE. IF THE TAPE ROLL WIDTH IS LESS THAN 2” (50 mm) ADJUST THE TAPE CORE. - FOLD BACK ABOUT 12” (300 mm) OF TAPE AND STICK IT TO ITSELF TO FORM A LEADER. THREAD TAPE AS SHOWN ON TAPE THREADING DIAGRAM. THERE IS ALSO A TAPE THREADING DECAL LOCATED ON THE TOP AND BOTTOM CARTRIDGE FRAMES. SPLICING PROCEDURES: - WITH A PAIR OF SCISSORS, CUT TAPE ON EXPIRING ROLL WHERE TAPE FEEDS INTO CARTRIDGE. REMOVE BUTT ROLL OF TAPE FROM TAPE CORE. - INSTALL A NEW ROLL OF TAPE ONTO TAPE CORE WITH TAPE FEEDING COUNTERCLOCKWISE. - SPLICE A ½ “ LAP TO CUT END OF TAPE. PULL TAPE THROUGH CARTRIDGE UNTIL SPLICE IS OUT OF CARTRIDGE. CUT SPLICE OFF.


LUBRICATION BEARINGS USED IN THE IDLER ROLLERS ARE PERMANENTLY LUBRICATED AND SEALED. BEARING BLOCKS, CHAINS, SPROCKETS AND THREADED SHAFTS SHOULD BE GREASED REGULARLY TO ENSURE FREE MOVEMENTS. THE MAST SHOULD BE CLEANED AND SPRAYED WITH A SILICONE LUBRICANT - THIS SHOULD BE DONE ON A WEEKLY BASIS TO INSURE FREE MOVEMENT OF THE HEAD.

TAPE CORE ASSEMBLY ADJUSTMENT PROCEDURES

(.TCA201 = 3” TAPE CORE AND .TCA301 = 2” TAPE CORE) STEP 1: UNLOCKING THE TAPE CORE FOR ADJUSTMENT: THERE IS A LOCKING BOLT USED TO MAINTAIN THE HEIGHT ADJUSTMENT OF THE TAPE CORE. THIS MUST BE LOOSENED TO CHANGE THE HEIGHT OF THE TAPE CORE. THIS WILL ALLOW YOU TO ADJUST THE HEIGHT OF THE TAPE (TRACKING) THROUGH THE CARTRIDGE. USING A 3 mm HEX KEY WRENCH TURN IN A COUNTERCLOCKWISE DIRECTION TO LOOSEN THE SOCKET HEAD CAP SCREW (SPH-1030). THEN TURN THE TAPE CORE NUT LP06B-039-3 (3”) OR PSC142-3 (2”) IN A COUNTERCLOCKWISE DIRECTION TO REMOVE DRAG FROM THE DISC SPRING (PSC33). BE SURE TO LOOSEN ENOUGH TO ALLOW THE TAPE CORE INTERNAL ASSEMBLY TO SPIN FREELY AND ADJUST UP AND DOWN. STEP 2: ADJUSTING THE TAPE CORE HEIGHT: THE INTERNAL ASSEMBLY IS THREADED ON A STUD MOUNTED ON THE CARTRIDGE MILL STAND. BY HOLDING THE EXTERNAL PART OF THE TAPE CORE ASSEMBLY AND ROTATING THE HEX LOCK NUT CAC50-101-3 (3”) OR CAC50-095-3 (2”) THE INTERNAL ASSEMBLY WILL ROTATE CHANGING THE HEIGHT OF THE TAPE CORE ASSEMBLY. TURN IN A CLOCKWISE DIRECTION TO DECREASE THE HEIGHT AND IN A COUNTERCLOCKWISE DIRECTION TO INCREASE THE HEIGHT. DO NOT OVER TIGHTEN THE INTERNAL ASSEMBLY. THIS MAY CAUSE DAMAGE TO THE TAPE CORE ASSEMBLY. RUN THE TAPE THROUGH THE CARTRIDGE AND CHECK FOR PROPER TAPE POSITION. REPEAT ADJUSTMENT AS REQUIRED TO CENTER TAPE. STEP 3: ADJUSTING TAPE ROLL BACK LASH OR FREE SPIN: THERE IS A DISC SPRING (PSC33) AND A SET OF BRAKE WASHERS (PSC28-3) USED TO SLOW THE FREE SPINNING OF THE TAPE ROLL CAUSED WHEN THE TAPE IS PULLED THROUGH THE CARTRIDGE.
