Introduction0‐4

HMIPUR01_EN_C-0108 � 2008 Nordson Corporation

Processing TemperatureWhen processing tempered materials, the prescribed processing temperature must be complied with to ensure high‐quality application. The temperature may not be exceeded! Overheating may cause charring or cracking ofthe material, which could lead to downtime or damage to the unit.

The material should always be melted gently. Avoid long, unnecessary exposure to heat. When work is interrupted, the temperature should be reduced.The temperature in the tank of the unit should be coordinated with the material consumption. When a large amount of material is consumed, the temperature should be set close to the prescribed processing temperature; lowerconsumption means a lower temperature.

When processing cold material, consider the influence of shear heat and ambient temperature. Cool if necessary.

Important Note for Polyurethane Materials (PUR)When processing polyurethane materials (PUR), the following additionalinstructions must be followed:

� When the maximum level of harmful substance concentration is exceeded, use a gas mask and air purifying equipment.

� During production stoppages or breaks, reduce the temperature andclose the applicator nozzle as well as possible. Cover the remainingopening with high-temperature grease or high-temperature tape.

� Before the application system is shut down for a longer period of time,rinse it with a suitable cleaning agent. Use only a cleaning agent recommended by the material manufacturer.

� Close open material connections so that they are airtight.

Introduction 2‐7


Adhesive Flow

The melter pumps the adhesive through a heated hose to the applicator. Inthe applicator the adhesive flows through the filter and the adhesive channelsto the nozzle. Control modules open and close the adhesive supply to thenozzle. The nozzle applies the adhesive to the substrate with contact.

The application pattern depends on the speed at which the substrate moves,the quantity of adhesive and the adhesive temperature. In addition, thequality of the application is influenced by the distance and the angle betweenthe nozzle and the substrate.

Nozzle

The nozzle touches the substrate, causing it to naturally wear.

Fig. 2‐5 Example of a nozzle

Shim Plate

The application pattern is essentially determined by the shim plate. The shimplate is located between the nozzle mouthpiece and the mouthpiecereceptacle. If there is no shim plate, the application pattern is milled into thenozzle mouthpiece.

Fig. 2‐6 Examples of shim plates with various application patterns

Introduction2‐8



Nozzle with Three Shim Plates

The nozzle can be equipped with one or three shim plates (Triple‐Shimversion). Two of the shim plates bear the pattern, while the center shim plate(B, Fig. 2-7) serves as a separator between the patterned ones (A, Fig. 2-7).

A

BA

Fig. 2‐7

The nozzle with three shim plates permits application of two differentmaterials to the same substrate surface at the same time.

It is also possible to apply two different material quantities (applicationweights or grammages).

Special Feature of the V-design

The V‐design of the applicator allows two control modules to be assigned foreach application zone. The adhesive paths are the same length. Dependingon what is required, the control modules are triggered differently. The controlmodules of an application zone open either at the same time or alternately.This enables the pauses between two applications to be very brief.

The nozzle in the V-design can also be equipped with one or three shimplates.

Introduction 2‐9


Speed‐Coat Control Module

Speed-Coat control modules precisely open and close the adhesive supplyto the nozzle by raising or lowering the nozzle stem. The adhesive is suckedback into the control module when the nozzle stem moves up. This ensuresthat the adhesive is cut off properly.

A compression spring ensures that the control module outlet is closed whencontrol air pressure drops, preventing adhesive from being applied.

The number of control modules is a factor of the greatest application widthpossible.

Introduction2‐10



Heating

The applicator is heated with electrical heater cartridges. The temperature iscontinuously measured by temperature sensors and is controlled withelectronic temperature controllers.

Filter Cartridge

The adhesive flows from the inside of the filter cartridge to the outside. Thusdirt particles remain in the filter cartridge.

There are two filter mesh sizes available. The size in microns (= micrometers,�m) is engraved in the collar of the filter screen:

0.08 mm = 80 �m = 80 microns and

0.10 mm = 100 �m = 100 microns

Special FeaturesThe table shows the special features that have been requested so far. Otherspecial aspects will continue to be described in separate manuals, customerspecifications or supplements.

Special feature Brief Description

Opti‐Stroke

(stem stroke detection)

Optical fibers can be attached to the control modules of the applicator.The movement of the nozzle stems in the control modules is compiled andtransmitted to the detection system as an optical signal.

The optical needle stroke detection system converts the optical signals todigital signals (switching times [ms]). This data can be processed with acontrol unit belonging to the customer. Also, a PC, e.g. for diagnosticpurposes, can be connected to the RS 232 interface.

Heat exchanger In the heat exchanger, the adhesive flows through long, winding channels,facilitating uniform heat transfer. The warm adhesive is heated to theprocessing temperature in the heat exchanger.

The adhesive feed hose is attached as described in the sectionInstallation.

The heat exchanger also has to be be connected electrically. Refer to thesystem plan for instructions.

Medium sensor The medium sensor measures the adhesive temperature just before theapplication nozzle.

Introduction 2‐11


Special feature Brief Description

Recirculation controlmodule

Recirculation control modules enable steady adhesive pressure in theapplicator. When the application control modules close and no adhesive isapplied, the recirculation control modules open, allowing the adhesive toflow back into the melter tank.

Recirculation control modules must be connected electrically andpneumatically. The instructions in the section Installation apply.

Recirculation hose Applicators with recirculation control modules are equipped with arecirculation hose. It may not be interchanged with the feed hoses.

The recirculation hose is attached as described in the section Installation.

Every hose connection is allocated to a corresponding receptacle on themelter or separate electrical cabinet. Do not mistakenly exchange! Referto the system plan for instructions.

Drain valve Drain valves are used to relieve the adhesive pressure in the applicator.They should be installed such that the adhesive can flow out the bottom.They are opened with a screwdriver. Do not loosen the screw completely!

Lotion nozzle A lotion nozzle allows low‐viscosity liquids to be applied with the aid ofadditional application air.

The application air must be supplied to the application nozzle separately. Itmay not contain any oil whatsoever; this would contaminate the lotion.

The application air is adjusted with a precision pressure controller:

0.1 to 0.3 bar / 10 to 30 kPa / 1.45 to 4.35 psi

Notes on Solenoid Valves with Temperature Markers

NOTE: Temperature markers have not been used since the beginning of2011.

On applicators manufactured before January 1, 2011, solenoid valves typeBooster were equipped with temperature markers. The markers indicatewhether the solenoid valve exceeded a certain temperature at any time.

If the temperature marker is light, the temperature was not exceeded.

If the temperature marker is dark, the temperature was exceeded.

NOTE: Unintentional external factors can also cause the color of thetemperature marker to darken.

CAUTION: The serviceable life of the solenoid valve may be reduced if itstemperature exceeds 80 °C.

Fig. 2‐10NOTE: A darkened temperature marker does NOT necessarily mean that thesolenoid valve can no longer function properly.

If the operating temperature recommended by Nordson for the applicator iscomplied with and the ambient temperature of the solenoid valve is below80 °C, the temperature of the solenoid valve will not exceed 80 °C.

NOTE: When the color of a temperature marker changes, Nordsonrecommends immediately checking functioning and, if necessary,immediately replacing the part.

Pneumatic ConnectionsNordson recommends using dry, controlled and nonlubricated compressedair.

Operation with Nonlubricated Compressed Air

When an applicator is connected to a compressed air system in which thecompressed air has previously been lubricated, simply ceasing to lubricatethe air is not sufficient. The oil remaining in the compressed air supply willreach the solenoid valves and the control modules and wash out the originallubricant/oil from these parts, substantially decreasing the service life of theunits.

NOTE: It must be ensured that the compressed air supply to the applicatorshas been converted to absolutely nonlubricated operation.

NOTE: No oil from a possibly defective compressor may be permitted topenetrate the compressed air supply.

NOTE: Nordson will assume no warranty or liability for damage caused byunpermitted, temporary lubrication.

Conditioning Compressed Air

The quality of the compressed air must be at least class 2 as stipulated byISO 8573-1. This means:

� Max. particle size 1 �m

� Max. particle density 1 mg/m3

� Max. pressure dewpoint -40 °C

� Max. oil concentration 0.1 mg/m3.

Connecting Compressed Air

1. Connect customer's air supply to the inlet of an air conditioning unit.

Maximum air pressure:

8 bar 0.8 MPa 116 psi

2. Connect the Speed-Coat control modules to the air conditioning unit.

3. Set control air pressure:

approx. 5 bar approx. 0.5 MPa approx. 72.5 psi

Installation 3‐5


Connecting Heated Hose


Connecting

If cold adhesive can be found in the hose connection (1, 2), thesecomponents must be heated until the adhesive softens (approx. 80 C, 176F).

1. First only connect the hose (3) electrically.

2. Heat the unit and hose until the adhesive softens (approx. 80 C / 176 F).

3. Screw on heated hose.

CAUTION: Special instructions apply to applicators fed from only one side!Refer to Applicators Fed from One Side on the next page.

Fig. 3‐2

Disconnecting

Relieving Pressure

1. Set motor speed(s) to 0 min-1 (rpm); switch off motor(s).

2. Place a container under the nozzle of the applicator.

3. Trigger the solenoid valve(s) electrically or manually. Repeat thisprocedure until no more adhesive flows out.

4. Properly dispose of adhesive according to local regulations.

Using Second Open-end Wrench

Use a second open-end wrench when connecting and disconnecting theheated hose. This prevents the hose connection on the unit from turning.

Fig. 3‐3

Installation3‐6


Connecting Heated Hose (contd.)

Applicators Fed from One Side

Observe Hose - Filter Combination

CAUTION: Always connect the hose to the side of the body where the filtercartridge is. This is the only way to ensure that the adhesive is filtered andthat adhesive can flow at all.

Changing Side

NOTE: The applicator cannot simply be rotated 180; then the nozzle wouldnot be correctly aligned to the substrate. The hose connections and filtercartridges have to be changed.

Observe the following: If the hose connection is moved from the right side tothe left, the position of the filter cartridge must also be moved from right toleft, and vice versa. Also refer to the following illustration.

ATTENTION: Relieve the applicator of pressure before unscrewing the hoseconnection, removing the plug from the material bore and extracting the filtercartridge.

Section 4

Operation


Triggering Solenoid ValveCAUTION: Trigger the solenoid valves only when the applicator is heated tooperating temperature!

Setting TemperaturesNOTE: The basis for temperature setting is the processing temperaturestipulated by the hot melt manufacturer (usually 150 to 180 °C / 302 to 356 °F). The maximum operating temperature of the product described heremay not be exceeded.

The applicator temperature required is set on the melter (maximum 200 °C /392 °F).

Setting Control Air PressureThe control air pressure is set to suit each application on an air conditioningunit. The air conditioning unit with pressure control valve is not part of theapplicator.

Set control air pressure:

Approx. 5 to 6 bar Approx. 0.5 to 0.6MPa

Approx. 72.5 to 87 psi

Nordson will assume no warranty or liability for damage caused by anincorrect pressure setting.

Operation4‐2


Setting Adhesive PressureThe adhesive pressure is generated by the melter pumps. The adhesivepressure can be monitored (optional feature) by a pressure sensor with aconnected pressure controller (e.g. ES 80).

To ensure that the adhesive pressure in the applicator remains stable:

Adhesive pressure inapplicator

Pump speed Result: Adhesivepressure

Too low Increase Increases

Too high Decrease Decreases

Maximum Adhesive Pressure

The maximum adhesive pressure may not be exceeded. Refer to TechnicalData.

Positioning ApplicatorThe optimum angle of incidence of the applicator is a factor of variouscustomer‐specific parameters and can not be determined preciselybeforehand.

Good application and adhesive cutoff is achieved when the applicator ispositioned almost completely vertical to the substrate. The angle can beadjusted within a range of approx. 80° to 100°

If the angle of incidence of the applicator to the substrate is too great, a beadof adhesive forms as soon as the adhesive is cut off. This soon leads toirregular adhesive application and a scaly application pattern.

Fig. 4‐1 Adhesive bead

NOTE: The optimum position of the applicator depends on several factors ofthe customer's specific application. Thus trial and error is the only way todetermine the best position. The fundamental differences are:

� Application of adhesive to open‐pore substrate (e.g. fleece)

� Application of adhesive to closed‐pore substrate (e.g. foil)

Operation 4‐3


Application with Contact Procedure

Application Against Web Tension

The applicator nozzle should be positioned between the inlet and outlet rolls,but not too close to the outlet roll.

Coating is not performed against the roll but against the tensed substrate.The applicator pushes approx. 1 to 5 mm into the substrate. This generatesmaximum substrate restoring force. The adhesive is constantly wiped off ofthe nozzle.

90< 90

> 90

Fig. 4‐2 Positioning Applicator

Application Against a Roll

NOTE: Speed-Coat applicators are generally not positioned against a roll.The roll must revolve perfectly concentrically and may not swing or bumpagainst the applicator. This would cause the nozzle to wear quickly, and theapplication quality would decrease.

Operation4‐4


Calculating Adhesive Quantity

Sample Calculation

Nordson recommends following the sample calculation before starting up theapplicator and making a note of the application‐specific values for applicationweight and width, substrate speed and pump output capacity in the tableCustomer specific‐Values.

These values can be used to calculate the pump speed and adhesivequantity.

Nordson also recommends entering results of the calculations in the table.This ensures that all values can be reproduced at any time.

NOTE: The material quantity for intermittent application is calculated thesame as for continuous material application.

Application weight (grammage) m = 20 g/m2

Application width of each adhesive track b = 10 mm = 0.01 m

Substrate speed v = 500 m/min

Adhesive quantity M = m � b � v = 20 g/m2 � 0.01 m � 500 m/min = 100.0 g/min

Output capacity of pump D = 2.4 g/revolution

Pump speed n = M � D = 100.0 g/min � 2.4 g/revolution � 42 rev/min
