Installation

WARNING

• To reduce the risk associated with sharp blade hazards:

− Keep hands and fingers away from tape cutoff blades under orange blade guards. The blades are

extremely sharp

Receiving And Handling

After the taping head assembly has been unpackaged, examine the unit for damage that might have occurred during transit. If damage is evident, file a damage claim immediately with the transportation company and also notify your 3M Representative.

Installation Guidelines

The taping head assembly can be used in converting existing or in custom made machinery. It can be mounted for top taping or bottom taping. Refer to "Box Size Capacities," as well as Figure 2-1 in the Specifications section, for the following points in making such installations:

CAUTION

• To reduce the risk associated with muscle

strain:

3. Figure 2-1 illustrates the typical mounting relationship for opposing taping head assemblies to allow taping of box heights down to 90 mm [31/2 inches]. To tape box heights down to 70

mm [2-3/4 inches], the taping heads must be completely staggered so only one tape seal is being applied at one time.

Note – AccuGlide™ 2+ STD Upper Taping Head is supplied with a buffing arm guard. Adjustments to this guard may be required to install the taping head into some older design 3M-Matic™ case sealers.

4. Mounting studs are provided with the taping head, but special installations may require alternate means for mounting.

5. Box hold-down or guide skis should be provided and the taping head mounted so that the side plates are 6 mm [1/4 inch] maximum away from the ski surface on which the box rides.

− Use proper body mechanics when removing

or installing taping heads that are moderately heavy or may be considered awkward to lift

Important – Always conduct a hazard review to determine appropriate guarding requirements when the installation is in an application other than 3M-Matic(TM) equipment

1. The box conveying system must positively propel the box in a continuous motion, not exceeding

0.40 m/s [80 feet per minute], past the taping head assembly since the box motion actuates the taping mechanism.

2. If a pusher or cleated conveyor is being used, steps should be taken in the conveyor design to

prevent the pusher from contacting the applying or buffing roller arms resulting in damage to the taping head.

Tape Leg Length

Taping heads are factory set to apply standard 70 mm [2-3/4 inch] tape legs. The heads can be converted to apply 50 mm [2 inch] tape legs if desired but both upper and lower heads must be set to apply the same tape leg length. See "Adjustments – Changing Tape Leg Length From 70 to 50 mm [2-3/4 to 2 Inches]."

Also, the conveyor speed at which the product moves through the taping heads, affects the leading and trailing tape leg length. See "Adjustments section – Leading Tape Leg Length Adjustment."

Tape Width Adjustment

Taping heads are factory set to apply 48 mm [2 inch] wide tape. If it is necessary to align the tape or to apply narrower tapes, refer to "Adjustments – Tape Web Alignment" for set-up procedure.

Blade Replacement, Upper and Lower Taping Heads – Figure 4-1

WARNING

• To reduce the risk associated with sharp

blade hazards:

− Keep hands and fingers away from tape

cutoff blade edge. The knives are extremely sharp

1. Loosen, but do not remove, the blade screws (A). Remove and discard old blade.

2. Mount the new blade (B) with the beveled side away from the blade holder.

3. Bottom the blade slots against the screws. (This will position the blade at the correct angle.) Tighten the blade screws to secure the blade.

Note – Check the blade position to insure proper clearance between blade and guard by slowly pivoting the blade guard back.

Blade Guard

The blade guard covers the blade whenever a box is not being taped. Periodically check to be sure the blade guard is functioning properly and returning to cover the blade. Replace any defective parts.

Blade Oiler Pad

WARNING

• To reduce the risk associated with sharp

blade hazards:

− Keep hands and fingers away from tape

cutoff blade edge. The knives are extremely sharp

Figure 4-1 – Blade Replacement

The taping heads are equipped with a felt oiler pad that has been pre-lubricated at the factory to provide a film of oil on the cutting edge of the blade to reduce adhesive build-up. Apply SAE #30 nondetergent oil as needed. Saturate felt oiler pad.

Should tape adhesive build-up occur on blade, carefully wipe clean with an oily cloth.

Maintenance (Continued)

WARNING

• To reduce the risk associated with shear, pinch, and entanglement hazards:

− Turn air and electrical supplies off on associated equipment before performing any adjustments,

maintenance, or servicing the taping heads

− Never attempt to work on the taping head or load tape while the box drive system is running

• To reduce the risk associated with sharp blade hazards:

− Keep hands and fingers away from tape cutoff blades under orange blade guards. The blades are

extremely sharp

Cleaning

Regular slotted containers produce a great deal of dust and paper chips when conveyed through taping heads. If this dust is allowed to build-up on the heads, it can cause wear on the moving parts. Excessive dirt build-up should be wiped off with a damp cloth. Cleaning should be done once per month, depending on the number and type of boxes used. If the boxes used are dirty, or if the environment in which the heads operate is dusty, cleaning on a more frequent basis may be necessary.

Note – Never attempt to remove dirt from taping heads by blowing it out with compressed air. This can cause the dirt to be blown inside the components onto sliding surfaces. Dirt in these areas can cause serious equipment damage. Never wash down or subject taping heads to conditions causing moisture condensation on components. Serious equipment damage could result.

Applying/Buffing Roller Replacement

Replacing roller requires removal of shaft and mounting screws. With no area on the shaft to grip, the shaft often turns when attempting to remove the second screw.

To ease removal of second screw, a 4 mm hex socket has been provided at the bottom of the threads in both ends of the shaft. Insert a 4 mm hex key wrench into this socket after removing one screw to hold the shaft for removal of the second screw. See Figure 4-3.

Figure 4-3 – Section View of Roller Shaft

Adjustments

WARNING

• To reduce the risk associated with shear,

pinch, and entanglement hazards:

− Turn air and electrical supplies off on

associated equipment before performing any adjustments, maintenance, or servicing the machine or taping heads

− Never attempt to work on the taping head or

load tape while the box drive system is running

Tape Latch Alignment – Figure 5-1 The Latching tape drum assembly is pre-set to

accommodate 48 mm [2 inch] wide tape. The tape drum assembly is adjustable to provide alignment of narrower tapes.

To move the latch to a position that corresponds to a new tape core width (Figure 5-1):

Figure 5-1 – Tape Latch Alignment

1. Remove screw from the latch.

2. Move to the latch to the position that corresponds to the tape core width.

3. Replace screw in the new latch location.

To adjust or center the tape width on the centerline of the taping head, and therefore box center seam, (Figure 5-2):

1. Loosen the locking hex nut behind tape drum bracket on tape drum shaft. Use an adjustable wrench or 25 mm open end wrench.

2. Turn tape drum shaft in or out to center the tape web (use 5 mm hex wrench).

3. Tighten locking hex nut to secure the adjustment.

No other components require adjustment for tape web alignment.

Tape Drum Friction Brake – Figure 5-3 The tape drum friction brake on each taping head is

pre-set for normal operation to prevent tape roll over travel. Should tension adjustment be required, turn

the self-locking nut on the shaft to vary compression of the spring. Turn the nut clockwise to increase the braking force, and counterclockwise to decrease the braking force.

Adjust brake to minimum tension to prevent excessive tape roll over travel.

Figure 5-2 – Tape Web Alignment

Note – Excess braking force will cause poor tape application and may lead to tape tabbing on the trailing tape leg.

Figure 5-3 – Tape Drum Friction Brake

Adjustments (Continued)

WARNING

• To reduce the risk associated with shear,

pinch, and entanglement hazards:

− Turn air and electrical supplies off on

associated equipment before performing any adjustments, maintenance, or servicing the machine or taping heads

− Never attempt to work on the taping head or

load tape while the box drive system is running

Applying Mechanism Spring

To obtain access to the spring, remove the taping head cover (four mounting screws). Replace cover when finished.

The applying mechanism spring, shown in Figures 5-4A and 5-4B, controls applying and buffing roller pressure on the box and returns the mechanism to the reset position. The spring pressure is pre-set, as shown in Figure 5-3A for normal operation, but is adjustable.

If a tape gap appears on the trailing surface of the box increase spring pressure. If the front of the box is being crushed by the applying roller decrease spring pressure.

Figure 5-4 – Applying Mechanism Spring

Removing the spring end loop from the spring holder and placing loop in other holes provided, as shown in Figure 5-3B, will adjust the spring pressure.

One-Way Tension Roller

Figure 5-5 The one-way tension roller is factory set. When

replacing this assembly, the roller must have 0,5 kg [1 lb.] minimum tangential force when turning.

To Adjust Tension:

1. Wrap a cord or small strap (non-adhesive) 4-6 turns around the tension roller.

2. Attach a spring scale to the end of the cord or strap.

3. Turn the adjusting nut with the socket wrench provided, until a force of approximately 0.5 kg to

0.9 kg [1 to 2 lbs.] is required to turn the roller by pulling on the spring scale.
