INTRODUCTION

Model UVD-AL offers your choice of vacuum or atmospheric double seaming. RANGE: 1½" to 6¼" diameter, up to 7" tall. Change parts are required for each size can. CAPACITY:   10+ Cans Per Minute - Atmospheric   8+ Cans Per Minute - Vacuum (Based on 15" Hg) OPERATION ATMOSPHERIC: Turn black selector switch to Atmospheric (ATMOS). Operator positions can with top and depresses the green start button. The can is double seamed automatically and the machine stops. Operator removes can and repeats the operation. It is not necessary to close the chamber door for atmospheric can seaming. VACUUM ONLY: Preset desired vacuum value (P1) a per instructions on page 2 for the Digital Vacuum and Gas Programer (648). Turn black selector switch to Vacuum Only (VAC ONLY). Operator positions can and top and closes the chamber door; the preset vacuum value is performed; the can is lifted and double seamed automatically then stops turning; remaining chamber vacuum is released. Operator opens door, removes can and repeats the operation. ***CAUTION*** BEFORE OPERATING YOUR DIXIE DOUBLE SEAMER REVIEW THIS MANUAL, supplementary information pertaining to the Vacuum Pump, Regulator, Motors and other auxiliary or accessory items furnished with this machine. Also make certain that: The machine is properly connected to your electrical supply. Auxiliary and accessory items are properly attached. Oil filling port on the vacuum pump is filled to recommended levels. *IMPORTANT* Use only SAE 20 motor oil. Capacity is 0.5 quart. All moving parts are oiled. These parts will require periodical oiling to prevent unnecessary wear. The machine is properly adjusted for the cans to be closed. Inspect machine adjustments periodically to assure proper results. The machine is cleaned and oiled as needed. If used occasionally or inactive for more than a few days, give special attention to servicing before and after storage.

The 648 Digital Vacuum and Gas Programer reads in inches of Hg.  Calibrations are in increments of 0.2" Hg.  The vacuum pump is rated 29.8" Hg; the maximum recommended vacuum value which may be entered is 29.8" Hg.  [The 648 Digital Vacuum and Gas Programer is rated ±0.5% accuracy.]  Use your finger to set a desired value in the program as explained below.

1. NOTE: The 648 Digital Vacuum/Gas Programer should display "0.0" when the machine is turned on under atmospheric conditions. If the display fails to read "0.0," reset by pressing the and keys simultaneously.
    
2. Press the SET button until P1 appears on the display followed by the current P1 value. (In the diagram above, 15 represents the current setting for the P1 mode).  Release the SET button.
    
   Press the key to increase the vacuum value for P1, or press the key to decrease the vacuum value for P1.
    
3. Continue pressing the SET button until the displays shows " 0.0." The vacuum value selected in the previous step is now programed into memory and the procedure is complete.
    

NOTE:  Only the P1 setting is recognized – any values which appear for P2, P3, or P4 have no effect.

Example - Vacuum Only:

A.  Set the digital programer to stop the vacuum pump at 18" Hg by setting the P1 mode at 18.

B.  See OPERATION for seaming instructions.
 

CHANGING DIGITAL PROGRAMER (648) TO DISPLAY mm Hg

The 648 Digital Programmer may be programmed to display millimeters of Hg. To change the display settings:

1. Press and hold the SET button until the display reads the current setting. Release the SET button.
2. Press the or key until the display reads mm Hg.
3. Press the SET button to store your changes to the display mode.

Set desired values as per above instructions, substituting mm Hg values for in Hg values. (NOTE: A convenient equation is 25 x in Hg=mm Hg.)

WARNING: The clutch/ brake/solenoid assembly is very complex. We recommend replacing the entire assembly (502-1) and returning the defective unit for factory repair for later use as a spare. Care should be used when removing this unit to avoid irreparable damage. More information on this assembly in included in a separate section.

Recommended air supply is 80-100 psi maximum. Different types of containers may require specific psi settings. The air pressure filter/regulator (816) on your machine has been set at the factory for the sample containers submitted with your order. If you find your air supply is inconsistent, or if you change containers or lids, you may need to adjust the air pressure filter/regulator. Too much air pressure may cause your container to crush your lid against the chuck. Too little air pressure will not lift the container against the lid properly. Any adjustments to the air pressure regulator should be made in small increments until a satisfactory pressure is achieved.

As a general rule, composite containers require a pressure setting of 70 psi; aluminum containers, 85 psi; and tin or steel containers require about 95 psi. However, particular container types may require minimal experimentation to determine the optimum pressure setting.

To set or change the air pressure, pull up on the black knob on top of the regulator until the orange band is visible. Turning the adjustment knob clockwise increases the pressure and turning the knob counterclockwise reduces the pressure. Adjust as necessary while observing the pressure gauge. Do not exceed 100 psi. Push down on the adjustment knob to lock air filter/regulator at selected psi to prevent accidental setting change.

The filter element should be changed after 1 year or when a pressure drop of 15 psi is reached. Periodically observe condensate level through sight glass in filter and manually drain as needed.

NOTE: Sufficient air pressure must be provided to cause the plunger of the air lift assembly (803) to extend to its locked position. Do not exceed 100 psi.

Proper base plate pressure is required to produce essential body hook, and also prevents slipping during the seaming cycle. Initially, the machine was set-up and adjusted to close cans size 603 x 700 then changed and tested for closing other size cans. Before shipping the machine was equipped and tested to close the cans specified on your order. To make minute adjustments in base plate pressure or to change to cans shorter than 7" proceed as follows: Cans 7" tall do not require a height spacer. Base plate pressure adjustments are made by loosening the 5/16" nut at the base of the 805 lift shaft then turning the lift shaft with a 5/8" open-end wrench at the "flats" on the lift shaft.   Cans shorter than 7" require a height spacer and a separate base plate which has an adjusting screw (57) and set screw (56) in it's stem. After loosening the set screw with a screwdriver inserted into the hole, the adjusting screw can be turned with fingers to the proper setting. After making adjustments, tighten jam nuts or set screw.

There are ten (10) revolutions per seaming cycle, five (5) for each seaming roll. The function of the first operation seam roll is to curl the cover hook and body hook into proper position. The second operation seam roll is to complete the sealing of the can.

1. Put machine in neutral position.
    
2. With power ON, press and release the actuator on the clutch/brake assembly four (4) times. Turn machine OFF, then press the actuator ONE more time to release the clutch brake. Then manually turn the clutch ONE HALF revolution. Grasp the collar (508) by hand, OR, use a wrench to turn the chuck shaft, to turn the assembly in a clockwise direction. These 4½ revolutions of the clutch/brake assembly places the first operation seam roll in its innermost position with the chuck.
    
3. While power to machine remains OFF, loosen lock nut (16) and adjust set screw (17-A) until the first operation seam roll is snugly in position with the chuck. While holding the first operation gauge wire (40) in position between the chuck lip and the ground profile of the first operation seam roll, tighten the lock nut. The larger diameter gauge wire (40) is the approximate THICKNESS of the first operation seam. Final adjustments may be made after a can is closed and the double seam inspected.

1. Turn power to machine ON which will automatically complete the fifth revolution. Press and release the actuator FOUR times and turn power to machine OFF. This is a total of nine (9) revolutions from the beginning and puts the second operation seam roll into its innermost position with the chuck.
    
2. Using your wrench and screwdriver, adjust the second operation seam roll into position. Use the second operation gauge wire (41) to fit the seam roll snugly in position with the chuck then tighten the lock nut. The small diameter gauge wire (41) represents the approximate THICKNESS of the second roll seam. Final adjustments may be made after a can is closed and the double seam inspected.
    
3. Press the actuator ONE time and turn power to machine ON to complete the 10th revolution and cycle. This will return the machine to its neutral position.
    
4. Close a can, tear down and inspect the double seam. Make final adjustments of the seaming rolls and base plate pressure to produce essential body hook, cover hook, overlap and tightness recommended by the container manufacturer or for a hermetically sealed can. NOTE: If you are unable to obtain the essential measurements recommended or a hermetically seamed container, you may need seam rolls with different profiles.

Change parts consisting of a chuck, a base plate and a height spacer may be required for each different can diameter, top or style. Also, a different set of seaming rolls may be required for each. Your can manufacturer or supplier may recommend the seam roll profiles for your cans. Dixie stocks or may be able to furnish the seam roll profile needed. Therefore, make sure you have the correct change parts available when changing your machine from one can size to another, then proceed as follows:

1. Put seam rolls in neutral position.
    
2. Loosen lock nuts (16) and adjust set screws (17-A) until both seaming roll levers (206) are back as far as they will go. If needed, change seaming rolls and/or reposition seam levers on the splined shafts (204). Leave the seaming roll levers backed into this position until after the chuck has been changed.
    
3. Change chucks. Make certain that the new chuck is properly tightened into position against the shoulder of the chuck shaft. CAUTION: (a) Use an open end wrench at the flat surface on the chuck shaft and the chuck wrench while loosening or tightening the chuck. Otherwise, the clutch/brake unit may be damaged. (b) If it is necessary to reposition 206 and 204, make certain the lip of each seaming roll runs freely in the chuck groove when in their innermost (seaming) position after the cap screws (322) are tightened.
   

   CHANGING CHUCKS
     To remove the chuck, hold the chuck shaft with a 5/8" wrench on the cut side of the shaft, located in the exposed area under the gear housing. Then place the two pins of the chuck wrench (44) provided with your seamer) into two of the four holes located on the bottom of the chuck. [The pins of the chuck wrench will fit into either diagonal or adjacent holes depending on the diameter of the chuck.] To loosen, turn the chuck to the left. Finish removing the chuck by hand.
   
   To install a new chuck, hold the chuck shaft with a 5/8" wrench, as described above, while using your hand to thread the chuck onto the lower end of the chuck shaft. Turn to the right to thread the chuck onto the chuck shaft. Use the chuck wrench, as described above, to tighten snugly.

4. When necessary remove and reset the seam roll levers (206) so the seam rolls will be about 1/2" from the chuck lip. Minimum travel of the seam roll levers is desired when turning the adjusting screws. CAUTION: Use a box wrench to loosen or tighten the bolt securing the seaming roll levers in position on the splined seam roll lever drive shaft. After tightening the bolt make certain that the lip of each seaming roll runs freely in the chuck groove when they are in their innermost (seaming) position and if necessary repeat the adjustment until the seaming roll levers are properly secured into position on the splined shaft.
    
5. Install the proper base plate and height spacer for the can to be closed. Adjust the base pressure and seaming rolls as outlined above.

The purpose of the can top retainer (201-5) is to hold the can top in position on the chuck, separated from the can, when desired. It is adjusted into position as follows:

1. After the machine has been properly equipped and adjusted for the size cans to be closed, place can top snugly into position on the chuck.
    
2. Adjust the can top retainer so the plunger is snugly against the can top curled edge and tighten the thumb screw.
    
3. If necessary, relocate the thumb screw to another hole. This allows a greater range of adjustments. Minute adjustments may be made by adjusting the lock nut and plunger.

Magnets are pressed in chucks fabricated for steel or tin can tops to hold the tops in position on the chuck. The can top retainers are not used for chucks with magnets.

The machine is in a neutral position when both cam rolls (20) are in their innermost position and both seaming rolls are in their outermost position

"Timing" and "in a neutral position" are synonymous. The machine is properly timed (or in neutral position) when both cam rolls (20) are at their innermost position and both seaming rolls (1st and 2nd) are at their outermost position. There are ten [10] revolutions per seaming cycle. Therefore, with power to the machine ON, by pressing the actuator on the clutch/brake assembly to turn the clutch/brake assembly one revolution at a time, the machine will have been "timed" by or before the 9th revolution. Then turn the power OFF, which allows the revolutions counter to "reset" while the machine is in a neutral position. Turn power ON again and continue closing cans.

If it should be necessary to turn the clutch/brake assembly less that a full revolution, proceed as follows. Turn power to machine OFF. Press the actuator one time to release the clutch brake. Grasp the collar (508) by hand, OR, use a wrench to turn the chuck shaft, to turn the assembly in a clockwise direction as needed. Turn power to machine ON and verify that the machine is now in time.

• Machine won't operate: 1. Solenoid (666) in vacuum and gas pipes won't open or close, or the solenoid in the clutch-brake assembly (502-1) doesn't work. 2. Air lift doesn't work, or 3. Direct Drive Motor doesn't run -- check FUSES.
  
     Open electrical box on rear of machine. Study the schematic drawing on the inside of the door, which details the fuses (3) and their individual function. The black, 3-section fuse box is located at the bottom-right section in the electrical box. Each of the sections have two (2) fuses -- one is a spare. Proceed to replace the top fuse, one section at a time until problem is solved. Order spare fuses as needed. NOTE: Two fuses are 4 amp and one is 10 amp.
  
      IF PROBLEM is not a "blown" fuse, your electrician may locate and correct a loose connection in the wiring -- or contact the factory.

• Vacuum pump "labors" or cuts off. 1st, check filter (412) and clean if dirty. 2nd, disconnect the union between the filter and vacuum chamber, then swivel elbow to expose inside of pipe and if clogged, clean and reconnect the union.
   
• Oil in the vacuum pump should be changed after 500 operating hours or every three months, whichever comes first.
   
• Machine won't stop, continues running. Check the clutch-brake (502-1) to see if the Magnet (664-A) is in place. The Sensor (664) needs the magnet in place on the clutch-brake to count each revolution. Use "Krazy Glue" to replace the magnet if needed.
   
• Power "accidentally" turned OFF during a seaming cycle will cause the machine to be "out of time" or "not in neutral."
   
• Close door and machine does NOT start: (659) switch and (659-1) magnet on door may be out of alignment. Realign and adjust to " space when door is closed.
