Section 2Description

This section contains a brief description of the Nordson AutomaticHopper/Feeder and how it operates. Specifications and measurementsfor the hopper/feeder are also included in this section.

The Nordson Automatic Hopper/Feeder is an accessory assembly thatmaintains the adhesive level in hot melt units. The hopper/feederreceives a signal from a level control sensor that causes the chute tovibrate and refill the tank with fresh adhesive: pillows, chiclets, slats,pellets, or granules.

1. Introduction

2. Equipment Description

Description2-2


46-267Issued 8/97


The hopper/feeder provides the following advantages:

S Reduces the time spent manually refilling the tank.

S Maintains a full tank of adhesive with less operator attendance.

S Stores adhesive and frees equipment for other tasks.

S Prevents thermal shock caused by refilling a tank that has run low.

S Reduces contamination that causes nozzle clogging.

S Allows access to the applicator for servicing without removing thehopper/feeder.

2. Equipment Description(contd.)

Description 2-3


46-267Issued 8/97


The adhesive is loaded through a hinged lid at the top of the hopper. From the hopper, the adhesive is deposited into a PTFE coated chute. A gate located between the chute and hopper/feeder hood is used to adjust the adhesive flow rate. The operator is able to monitor the level of adhesive in the hopper/feeder through a window in the hopper wall.

A level control sensor mounted in the hood indicates when the adhesivehas reached a preset low level. The control energizes a vibrator thatcauses the adhesive to flow from the hopper/feeder into the applicatortank. When the adhesive reaches a preset high level in the tank, thelevel control sensor de-energizes the vibrator. An excess demand alarmactivates if the vibrator remains on for an excess amount of time. Theoperator can set this time and make adjustments to the vibrationmagnitude and level control sensitivity in the electrical control box. Thisbox is located on the hopper front panel above the hood.

This section contains the procedures necessary to operate thehopper/feeder with your hot melt unit. All operator controls and indicatorsare located on the electrical control box front panel. To obtain optimumadhesive flow from the hopper/feeder, you can make the followingadjustments to:

S the Flow Control GateS the Vibration MagnitudeS the Level SensitivityS the Excess Alarm Demand

1. Introduction

Operation4-2


46-267Issued 8/97


Use the following procedure to prepare the hopper/feeder for initialoperation.

1. Turn power on to the unit.

CAUTION: Do not use pressure sensitive materials in thehopper/feeder. Pressure sensitive will stick to the hopper walls.Use dry adhesive only.

2. Fill the hopper with dry adhesive.

3. Turn the hopper/feeder power on using the toggle switch. ThePOWER ON indicator LED will light.

Fig. 4-1 Electrical Control Box Front Panel

2. Initial start-up

Operation 4-3


46-267Issued 8/97


The flow control gate determines the adhesive flow rate from thehopper/feeder through the chute and into the unit tank. The flow controlfactory setting is set at the lowest position (slowest flow rate). In thisposition, dry adhesive can feed from the chute into the hood and unittank.

If you need to adjust the flow rate, use the following procedure:

1. Remove the hopper/feeder hood lid.

2. Press and hold the FEEDER TEST button to activate the vibrator,then observe the flow of dry adhesive from the chute into the hoodand unit tank. Dry adhesive should sprinkle not pour from the chute.

3. Release the FEEDER TEST button. If adjustment is required, loosenthe flow control gate knob.

4. Raise and lower the knob (with the gate attached) and press theFEEDER TEST button to feed adhesive from the chute. Observe theflow rate through the top of the hopper/feeder hood. Move the gateup to increase flow and down to decrease flow.

5. Tighten the flow control gate knob when the desired flow rate isachieved.

6. Continue to the next procedure, Adjusting the Vibration Magnitude.

3. Adjusting the Flow Rate

Operation4-4


46-267Issued 8/97


The vibration magnitude setting is based on the size of the adhesiveforms used in the hopper/feeder. Generally, larger adhesive forms with aslower flow rate require an increased vibration magnitude. Smalleradhesive forms with a faster flow rate require a decreased vibrationmagnitude.

Use the following procedure to adjust the vibration magnitude:

1. Remove the hopper/feeder hood lid.

2. Press and hold the Feeder Test button to activate the vibrator, thenobserve the flow of dry adhesive from the chute into the hood and unittank. Dry adhesive should sprinkle not pour from the chute.

3. Release the FEEDER TEST button. If adjustment is required,continue to step 4.


4. Disconnect and lockout external power to the unit.

5. Open the electrical control box and locate the vibration magnitudepotentiometer R26.

4601037

4. Adjusting the VibrationMagnitude

Operation 4-5


46-267Issued 8/97


6. Use a small screwdriver to turn the potentiometer R26 clockwise toincrease the vibration or counterclockwise to decrease the vibration.

7. Close the electrical control box. Retighten the captive screws thatsecure the control box.

8. Apply power to the unit and repeat step 2. Repeat this procedureuntil the desired flow rate is achieved.

9. Continue to the following procedure.

The level control sensor indicates when the adhesive reaches a presetlow level. If the level control sensor is properly adjusted, thehopper/feeder fill sequence begins and remains on until the adhesivelevel is within 2.54 cm (1 in.) of the sensor.

Use the following procedure to set the desired low level.

1. Press and hold the FEEDER TEST button to activate the vibrator,then observe the flow of dry adhesive from the chute into the hoodand unit tank. Dry adhesive should sprinkle not pour from the chute.

2. Release the FEEDER RESET button when the level of dry adhesiveis 2.54 cm (1 in.) below the sensor probe.

NOTE: The sensor probe is not damaged by contact with the dryadhesive.


3. Disconnect and lockout power to the unit.

4. Loosen the captive screws that secure the electrical control box, andopen the control box.

CAUTION: Do not touch the sensor cable inside the controlunit. Touching the cable may activate the vibrator.

6. Use a small screwdriver to locate the sensitivity scale mid-range byturning the level control potentiometer at least 15 turns in onedirection, and 7 to 8 turns in the opposite direction. Clockwiseadjustment (max) increases probe sensitivity and lowers the adhesivefill level in the hood. Counterclockwise adjustment (min) decreasesprobe sensitivity and raises the adhesive fill level in the hood.

The excess demand alarm activates if the vibrator remains on for anexcess amount of time. Usually, if the vibrator remains active for morethan a ten seconds, the hopper/feeder is out of adhesive or the adhesiveis clogged in the chute. This alarm alerts the operator when adhesive isnot flowing from the hopper/feeder.

Use the following procedure to set the time elapse before the alarm willactivate. Complete this procedure BEFORE you add adhesive to thehopper/feeder unit.


1. Disconnect and lockout power to the unit.

2. Open the electrical control box and locate the excess demand alarmpotentiometer R20 on the inside panel.

4. Close the electrical control box, and secure the captive screws.

5. Apply power to the unit. Check for the desired time period before thealarm activates. When the FEEDER ON time exceeds the presettime elapse, the FEED FAILURE indicator LED should light and theexternal alarm should activate.
