2. Overview Nordson CF-200 dispensing modules use Controlled Fiberization technology to apply a continuous strand (bead) of thermoplastic adhesive in a spiral (helix) pattern to material moving on a conveyor below (see

- Figure 9-l).

3. Nozzle 6. Substrate

This helix pattern of the continuous bead of adhesive provides both application control and a wide area of coverage. The combination of application control and wide area of coverage make this dispensing module ideally suited to the nonwovens industry.

This document describes the high performance, CF-200-HP dispensing module. This version of the CF-200 module is different from the standard version in two ways. First, the CF-200-HP is equipped with a needle and seat instead of a ball and seat arrangement for adhesive shutoff. This allows for more responsive cutoff.

Second, the CF-200-HP is equipped with a micro-adjust capability for more exact control of adhesive output from the module.

The dispensing module controls the flow of adhesive onto the substrate. Adhesive is pumped from the pattern plate (to which the module is attached) and into the module through a passage in the module body. The flow of adhesive out from the bottom of the module is controlled by an internal, spring-loaded piston attached to a needle.

CF-ZOO-HP Dispensing Modules 9-3

__ Module Operation (contd.) Operating air from the pattern plate enters the module at a separate hole in the module body and forces the piston up, pulling the ball up from its seat. Hydraulic pressure forces the adhesive out of the module and through an opening in the seat.

When the operating air pressure decreases, the internal spring forces the piston down, causing the needle to close the adhesive output at the seat.

The length of the adhesive bead is controlled by the time period during which the needle is off the seat.

A separate air supply from the heated air manifold enters the CF nozzle cavity area at the base of the module and is used to create the helix pattern of the adhesive.

Air pressure forces the air out of this cavity through pattern air holes that surround the adhesive opening in the nozzle. These pattern holes in the nozzle direct the pattern air towards the center of the nozzle at an angle, which creates the helix pattern of the adhesive as it flows towards the substrate.

As stated earlier, the CF-200-HP is a needle-and-seat valve with microadjust capability. The advantage of the needle-and-seat arrangement is the decreased chance for char blockage of the nozzle orifice(s).

The microadjust feature allows flow adjustment or balancing in multi-module applications.

3. Dispensing Module Troubleshooting

Table 9.1, Dispensing Module Troubleshooting Guide, lists typical problems that can occur during the operation of a CF-200 dispensing module, possible causes, and corrective action for each possible cause.

Note: The Nordson Hose/Gun Diagnostic Device allows precise and complete heater and RTD troubleshooting on devices equipped with 120 ohm nickel RTDs. The device enables you to quickly accomplish RTD and heater troubleshooting without removing the applicators from their supply hoses. Contact your Nordson representative for further information.

5. Synchronizing the Modules

This material applies only to applications where a common solenoid is used to trigger two or more modules.

All modules are factory-set so that during a single cycle, the positions of the adhesive patterns on the substrate are synchronized. Consequently, there is no need to adjust dispensing module timing following installation. Also, continuous applications do not require dispensing module synchronization. (Continuous applications are applications in which the dispensing module is open for long periods, resulting in a long, continuous series of helix-shaped patterns of adhesive on the substrate.)

However, after dispensing modules have been in use for a period of time, it might be necessary to synchronize the adhesive pattern placement on the substrate for intermittent applications. (Intermittent applications are applications in which the module opens and closes frequently, resulting in numerous short helix-shaped adhesive patterns.)

A lock nut and load screw arrangement at the top of the dispensing module allows for slight adjustments to module timing. By loosening the lock nut and turning the load screw, the location on the substrate where the adhesive stream strikes can be moved forward or backward to align adhesive patterns on the substrate.

To synchronize the dispensing modules:

1. Trigger the modules to pump adhesive onto a moving substrate. Note the position of the patterns on the substrate.

2. If adjustment is needed, use a wrench to loosen the locking nut at the top of the chosen dispensing module and a screwdriver to adjust the loading screw (see Figure 9-9).

3. Perform one of the following adjustments as required by the placement of the adhesive patterns (see Figure 9-10):

a. To decrease the length of the adhesive pattern in the target area on the substrate, use a slotted screwdriver to turn the loading screw clockwise. This adjustment shortens the length at both ends of the patterns.

b. To increase the length of the adhesive pattern in the target area on the substrate, use a slotted screwdriver to turn the loading screw counterclockwise. This adjustment increases the length at both ends of the pattern.

Note: The micro-adjuster is factory-set for maximum output.

1. Use a 7116 in. (11 mm) wrench to loosen the top lock nut.

2. With a screwdriver holding the load screw stationary, use a 5/8 in. (16 mm) wrench to turn the micro-adjusting nut clockwise to reduce pattern thickness. The micro-adjusting nut is the next hex fitting below the top lock nut. See Figure 9-11.

CAUTION: Do not back the micro-adjusting nut out any further from its factory setting. Doing so will cause the gun to release hot melt material from the nozzle even though the gun is not triggered.

3. Tighten the top lock nut and lockwasher to 5 ft-lb (6.7 Nom), taking care not to change the load screw position.

7. Disassembly and Repair The instructions for disassembling and rebuilding CF-200 dispensing modules are included in the dispensing module service kits. The dispensing module service kits are listed in CF-200 Standard Module Sewice Kits and Suggested Spare Parts list later in this section. Refer to the module rebuilding instructions included with the service kit to disassemble and rebuild a CF-200 dispensing module.

Removing and Replacing a Dispensing Module

Use the following procedure to remove and replace a CF-200 dispensing module:

1. Relieve the hydraulic pressure by following the procedure described in Relieving Hydraulic Pressure in Section 7.

2. Disconnect and lock out input power from the motor.

3. Wear safety gloves, safety goggles, and protective clothing.

4. Trigger the applicator to relieve any hydraulic pressure remaining in the applicator and dispensing module.

5. Shut off the supply of operating air to the applicator. This is the air supply that causes the dispensing module to open. (Each independent dispensing module or group of dispensing modules is supplied with operating air from a solenoid valve.)

6. Reduce the process air pressure to a small value to prevent adhesive from entering the air hole in the heated air manifold. (Process air is the air supplied to the module from the heated air manifold that creates the helix pattern of the adhesive.)

15. Replace and tighten the two socket-head screws that secure the dispensing module to applicator. Torque the screws to 30 lb-in (3.39 Nom).

Note: Do not over-tighten the screws. Over-tightening can cause the head of the screw to break off.

Note: For best results, torque the screws again after the applicator reaches operating temperature.

16. Restore the hot melt system to normal operation as described in the melter service manual.

CF-200-HP Dispensing Modules 9-29

IO. Controlled Fiberization Spray Nozzles

Three types of Controlled Fiberization spray nozzles are available for CF-200 modules:

l disk

l cap

l unibody

Disk spray nozzles are held on the dispensing module by a retaining nut. A disk nozzle is protected from damage by being recessed inside the retaining nut when attached to the module. Refer to Table 9-11 for information about disk nozzles.

Cap and unibody spray nozzles are designed with the disk and retaining nut as a single assembly. This design allows for ease of cleaning because there are no recessed surfaces as with the disk spray nozzles. Refer to Table 9-l 2 for information about cap nozzles and to Table 9-13 for information about unibody nozzles.
