1.0 INTRODUCTION

The SH-400F flexible disc hopper complements the extensive Asahi Seiko range ofhoppers giving customers the option of changing the calibration of their hoppers tosuit different coin sizes without the need for additional parts.

The range of six disc sizes available in the standard hopper is replaced with a singledisc and adjusting plate to cater for coins within the range of 21mm - 28.5mm indiameter and 1.4mm - 3.2mm in thickness.

The overall dimensions and electrical specification remain unchanged although thehopper is currently only available with a 24vdc motor.



2.0 GENERAL SPECIFICATION.

2.1 Coin Size Range

Diameter 21.0mm - 28.5mmThickness 1.4mm - 3.2mm

2.2 Hopper Head Capacity

The following table gives examples of average capacities. Each additionalextension head increases the capacity by approximately 80%.

Coin Diameter ApproximateCapacity

20.0mm diameter 70023.5mm diameter 55026.5mm diameter 400UK 5p coins 800UK 10p coins 400UK 20p coins 500UK £1 coins 280

Note: The previous examples of head capacity for non-specific coins areapproximate as the volume of coins is also dependent upon thickness.

2.3 Dispensing Speed

The dispensing speed of the SH-400F is 400-600 coins per minute. Speedmay vary due to coin characteristics such as diameter, thickness and loading.

2.4 Installation

Temperature range: -10°C to +50°CHumidity: 15 - 85% RH (avoid condensation)Location: Indoors within a cabinetTemperature rise: 50ºC maximumOrientation: Mount within 2º of upright



2.5 Weight

Approximately 0.4Kg when empty.

2.6 Storage Conditions

Storage temperature: -20ºC to +80ºC without condensation

2.7 Mechanical Life

In reliability tests, the SH-400F hopper has dispensed over 2,000,000 coinswithout mechanical failure.



3.0 OPERATION AND MAINTENANCE

The chassis mounting plate for the motor/gearbox assembly and coin disc is inclinedat 30º to the horizontal.

A disc with holes set slightly larger than the coin diameter rotates in a clockwisedirection collecting coins from the base of the hopper and moving them towards thepayout point at the top of the mounting plate.

When the coin held in the disc approaches the payout point, two spring-loaded pins inthe base deflect it sideways beneath the bowl allowing it to be dispensed between tworollers, one of which is spring-loaded. The coin then passes out through the sensorwhich provides pulses of between 10ms and 30ms in duration (dependent upon coindiameter).

When the control signal is removed (see Section 4.4.1), the motor is stopped instantlyby the DC motor brake. The motor brake briefly applies reverse current to preventoverrun, ensuring accurate coin dispensing.

3.1 Removing/Replacing the Hopper Bowl

To remove the bowl, depress the bowl lock pin (part 37) located below thelower edge of the bowl and turn the bowl clockwise. Lift the bowl clear of theretaining pins.

Replacement is the reverse of the removal operation.

3.2 Removing/Replacing the Coin Disc

With the hopper bowl detached, remove the large domed head screw (part 61)in the centre of the disc. The disc (part 22) can now be lifted off and adjustedto suit a different coin diameter if required.

Note: When adjusting the coin disc for change of coin diameter it may benecessary to adjust other clearances. Refer to Section 5 on hoppercalibration.



3.3 Safety And Maintenance

3.3.1 Control circuitry must be arranged to disconnect power to themechanism when the host machine is opened for servicing.

Removal of the hopper connector, without first disconnecting thepower source, may result in damage to the optical sensors.

3.3.2 Over-current protection is not provided on the mechanism. Customersare strongly recommended to provide suitable fusing arrangements inevent of equipment failure.

3.3.3 The mechanism control board detects a stall situation and initiatesmotor reversals to free jams. Control circuitry should be arranged todisconnect power if this situation exceeds 10 seconds maximum, toprevent motor damage.

3.3.4 Servicing and maintenance staff must be adequately trained and awareof the hazards arising from the rotating disc. Fingers, long hair andloose clothing, including ties, must be kept clear at all times.

3.3.5 Avoid handling the unit by the bowl only, as this could becomedetached if not correctly located, thus causing possible injury ordamage.

3.3.6 Prevent foreign objects such as elastic bands, paper clips and screwsfrom entering the hopper bowl.

3.3.7 Regular cleaning of optical sensors is advisable to prevent miscounting.

3.3.8 When cleaning the bowl, use a diluted neutral detergent and dry with aclean cloth.

3.3.9 Wiring errors are a common cause of problems, particularly with thesensors which can be damaged with a relatively small voltage overload.

4.3 Electrical Characteristics

To achieve optimum performance the power supply must be able to match therequirements of the table below.

The SH-400F hopper is designed for intermittent use and continuous run timemust not exceed 3 minutes maximum.

4.4 Control

4.4.1 Driving the Hopper

JST Connector DescriptionPin 1 SupplyPin 2 Ground (0v)Pin 3 Motor on +vePin 4 Motor on -ve

Provide Pin 1 with 24vDC and Pin 2 with 0v constantly. Motor On+should be pulled high to a reference voltage of between 5vDC and12vDC for interfacing ‘directly’ with host machine control circuitry. Ifconnection of Motor On+ to a higher voltage is desired, then use of apull up resistor is recommended to limit the current to between 8mAand 23mA.

To drive the hopper the host machine must pull Motor On- down tobelow 1.0v DC. This can be achieved by use of a switch, relay or opencollector transistor. The following current will be drawn: -

Motor On+ (reference voltage) Current Drawn5v DC 8mA12v DC 23mA

Table 4.4.1

4.5 Payout Sensor Specifications

Two sensor options are available, optical and proximity. The wiringconnections for both options are identical allowing interchange between eithermodel.

Both sensors now incorporate an additional check lead to permit performancechecks to be performed by the host machine prior to dispensing.

Lowering the potential on the check lead to zero volts simulates a coin pulseand the host interface can be designed to inhibit payout if this pulse is notseen.

5.0 CALIBRATION INSTRUCTIONS

5.1 General

Re-calibration for change of coin size will generally necessitate re-adjustmentsto the following parts of the hopper:

• Disc adjusting plate• Disc height adjuster• Coin guide• Coin output rollers

5.2 Disc adjustment to suit coin diameter

• Remove the hopper bowl by depressing the lock pin at the lower right handedge of the bowl.

• Slacken the disc retaining screw in the centre of the disc.

• Remove the three small countersunk adjusting plate retaining screwslocated around the edge of the disc using a small Phillips screwdriver,taking care not to damage the screw heads.

• Select the adjusting plate setting applicable to the coin (see Table 5.2) andreplace the three retaining screws in the appropriate holes (see Figure 5.2).

• Tighten the disc retaining screw in the centre of the disc.

5.3 Disc Height Adjustment

It is necessary to adjust the disc height to permit coins to exit freely beneaththe disc when they reach the payout point. The disc is adjusted to give aclearance between the underside of the disc and the coin face of 0.3mm –0.5mm by re-positioning the plastic height adjuster on the underside of thebase plate.

• Slacken the two screws holding the white plastic shaft clamp on theunderside of the base plate.

• Slacken the clamp screw for the shaft adjuster (white plastic withelongated slot on the underside of the base plate).

• Adjust the shaft height to achieve a clearance of between 0.3mm and0.5mm between the coin face and the underside of the disc (see Figure5.3).

Note: For coins greater than 2.5mm thick it is necessary to add anadditional 1mm thick washer beneath the disc.

• Tighten the shaft adjuster clamp screw.

• Tighten the shaft clamp screws to achieve perceptible end float on the shaftof 0.1mm – 0.2mm.
