Abstract

The innovation will present a simple way to control large electric motors in conveyor belts, carousel, etc. It will consist of a Light Dependent Resistor (LDR) which is the major component. It will make the motors stop and move intermittently, at very regular intervals or depending on the preferences of the operator. This will replace the need for complex algorithms and other controller configurations. The arrangement of the ldr and light source will be housed in a dark cardboard or plastic cube box. Within the cube box, there will be a small, upright positioned and flat cylindrical box suspended within the cube box and made from plastic. The flat cylindrical box is free to rotate on its axis, within the cube box, with the aid of a small electric motor. Inside the cylidrical box, there will be a stationery unidirectional light source.  On the side of the cylindrical box, there will be slits to allow the lights to intermittently flash on the ldr placed directly in front of it, facing the side of the flat cylindrical object as it rotates. The slits will be separated partly according to the frequency at which the light will be flashed. The other factor that will determine the frequency will be the speed of the motor for rotating the cylindrical box. The motor must also possess speed control. These two factors will ensure that the operator attains whatever frequency of which the light falls and blanks from the ldr.

There is also the alternative of using an a stable multivibrator to control the frequency of the flashing unidirectional light source. This method will eliminate the need for the inner cylindrical box. The arrangement will simply consist of a dark plastic  box with the ldr in the inner wall of the box and the unidirectional flashing light sourceon the inner wall of the cube box directly facing the ldr.

Introduction

The innovation will present a simple way to control large electric motors in conveyor belts, carousel, etc. It will consist of a Light Dependent Resistor (LDR) which is the major component. It will make the motors stop and move intermittently, at very regular intervals or depending on the preferences of the operator. This will replace the need for complex algorithms and other controller configurations. The arrangement of the ldr and light source will be housed in a dark cardboard or plastic cube box. Within the cube box, there will be a small, upright positioned and flat cylindrical box suspended within the cube box and made from plastic. The flat cylindrical box is free to rotate on its axis, within the cube box, with the aid of a small electric motor. Inside the cylidrical box, there will be a stationery unidirectional light source.  On the side of the cylindrical box, there will be slits to allow the lights to intermittently flash on the ldr placed directly in front of it, facing the side of the flat cylindrical object as it rotates. The slits will be separated partly according to the frequency at which the light will be flashed. The other factor that will determine the frequency will be the speed of the motor for rotating the cylindrical box. The motor must also possess speed control. These two factors will ensure that the operator attains whatever frequency of which the light falls and blanks from the ldr.

There is also the alternative of using an astable multivibrator to control the frequency of the flashing unidirectional light source. This method will eliminate the need for the inner cylindrical box. The arrangement will simply consist of a dark plastic  box with the ldr in the inner wall of the box and the unidirectional flashing light sourceon the inner wall of the cube box directly facing the ldr.

The slits on the side of the flat cylinder housing the unidirectional light source, preferably a laser (like those for targeting on rifles), will allow its light flash through the slits and when the light falls on the ldr, it turns off the motor for the machine controlling the carousel for dispensing toothpaste intoa tube, for instance. When the light source is blocked by the interval before the next slit, as the cylinder rotates, the carousel continues instantly by either starting the motor or releasing the motor braking device or perhaps another machine comes on to bring the toothpaste tube to position for the next round of toothpaste dispensing. In this fashion, the ldr and slit arrangement alone can control the dispensing of the toothpaste or lotion and also control the other motor for the positioning of the tube by being cascaded with the ldr.

The arrangement I have proposed can be used to control the operation of other processes within the factory without the need for complex controller systems. There will also be a safety process that involves the electronic monitoring of the motor that rotates the flat cylinder with the slits. The monitoring system will initiate a shut down of the process in the event the motor stops working or experiences an alteration in its parameters. This can be achieved through a simple transistor voltage divider switch whereby the altered characteristics of the motor will present as a resistance value on the voltage divider arrangement.

DIMENSIONS OF THE CUBE BOX, CYLINDER BOX AND DESCRIPTION OF ARRANGEMENT

The cube box is 22cm length and breadth. The cylinder box which will be housing the light source, is height 7cm and diameter 14cm. The boxes will be made of dark colored plastic. The cylinder will be upright positioned within the cube box. The motor for rotating the cylinder will be stuck to the inside of the top of the cube box and the shaft connected to the center of the cylinder. This will ensure that the cylinder spins rightly. The light source will be stuck to one end of a plastic cylindrical stick of height of 15cm and diameter of 3mm. The other end will be stuck in the inside of the bottom of the cube box housing the suspended cylinder. The light source on the stick will be placed on the center of the cylinder and enough allowance on the hole made under the cylinder for it to spin without constraints.

The electric motor spinning the cylinder should be able tohave speed control.

CHARACTERISTICS OF THE LIGHT DEPENDENT RESISTOR AND THE RELAY

The light dependent resistor controls the operation of a relay attached to it, through a circuit. The appropriate circuit for instant operation of relay(in milliseconds) and therefore operating the motors instantly is given below.

Relay for energising contactor coil

The relay may be users to energize the contactor coil and thus control the mains supply to the braking device for motor control. The braking device can be a solenoid break or magnetic brake or any other control structure.

USE OF A STABLE MULTIVIBRATOR TO CONTROL THE FREQUENCY OF THE FLASHING LIGHT

An a stable multvibrator usually has a variable resistor to control temperature. The frequency in which the carousel or conveyor belt will be made to start and stop to, for instance, dispense the right amount of toothpaste in a tue, will be according to the flashing of the unidirectional light source shining on the ldr.

Conclusion

The equipment for this innovation is extremely easy to fabricate or procure. The entire system is extremely light. The relay circuit, preferably, should be run by a 9v battery whose life can be determined and therefore replaced before totally discharging. This will ensure that the relay last very long by prevent high in-rush current and high voltage spikes that will be experienced from the rectification of mains supply. Mains supply may be used if the operator is convinced that there are enough protective mechanism to prevent voltage spikes. The relay should be electromagneic type. The owner of the innovation can decide to use an a stable  multivibrator to control the light source and thereby control the motors or can use an revolving cylinder withe a light source and slits at the side.
