A AUTOMATIC POOR QUALITY REJECTION USING CONVEYOR

AUTOMATION.

bstract

To perform the Automatic Poor Quality Rejection using conveyor

automation.

SYNOPSIS:

The Automatic poor quality rejecter sense and deliver the right

product and ejects outs the poor quality products.

The product is moved to the Sensor Cabin to verify the quality

through the Conveyor. The Dimension of the product is checked using the Sensor

Interface. If the product has no accurate dimension the rejecter rejects the product

to the Rejecter Bin. If the product has high quality the conveyor moves it to the

Accepted Bin. The motor is used to move the Conveyor that carries the product.

The Micro Controller is used to sense the product using sensor interface, control

the rejecter using rejecter control, control the motor using motor driver. The Power

Supply provides power to the all the parts of the systems

Micro controller

A microcontroller (sometimes abbreviated µC, uC or MCU) is a

small computer on a single integrated circuit containing a processor core, memory,

and programmable input/output peripherals. Program memory in the form of NOR

flash or OTP ROM is also often included on chip, as well as a typically small

amount of RAM. Microcontrollers are designed for embedded applications, in

contrast to the microprocessors used in personal computers or other general

purpose applications.

Microcontrollers are used in automatically controlled

products and devices, such as automobile engine control systems, implantable

medical devices, remote controls, office machines, appliances, power tools, toys

and other embedded systems. By reducing the size and cost compared to a design

that uses a separate microprocessor, memory, and input/output devices,

microcontrollers make it economical to digitally control even more devices and

processes. Mixed signal microcontrollers are common, integrating analog

components needed to control non-digital electronic systems.

Some microcontrollers may use four-bit words and operate at

clock rate frequencies as low as 4 kHz, for low power consumption (single-digit

milliwatts or microwatts). They will generally have the ability to retain

functionality while waiting for an event such as a button press or other interrupt;

power consumption while sleeping (CPU clock and most peripherals off) may be

just nanowatts, making many of them well suited for long lasting battery

applications. Other microcontrollers may serve performance-critical roles, where

they may need to act more like a digital signal processor (DSP), with higher clock

speeds and power consumption.

Motor Drive

A motor drive, in the field of photography, is a powered film

transport mechanism. Historically, film loading, advancing, and rewinding were all

manually driven functions. The desires of professional photographers for more

efficient shooting, particularly in sports and wildlife photography, and the desires

of amateur and novice photographers for easier to use cameras both drove the

development of automatic film transport. Some early developments were made

with clockwork drives, but most development in the field has been in the direction

of electrically driven transport.

At first, motor drives were external units that attached to the

basic camera body, normally beneath it, with an interface consisting of a physical

drive socket and some electrical contacts to signal the drive when to actuate.

Beginning in the late 1970s, motor drives began to be integrated into cameras

themselves—at first, in compact cameras for the beginner market, and by the

1980s, in amateur-grade and later professional-grade single lens reflex cameras. By

the 1990s, the vast majority of 35mm cameras had integral motor drive, and the

feature found its way into some medium format cameras as well.

Motor drives for compact and amateur cameras wind slowly

—shot-to-shot intervals of approximately a second are commonplace. Professional

grade cameras are faster, with speeds up to 10 frames per second. The first 35 mm

SLR to achieve such a shooting speed was Canon's F-1 High Speed Motor Drive

camera, first developed for the 1972 Winter Olympics in Sapporo, Japan. To

enable this speed and allow the photographer to more easily track the moving

subject, this camera used a fixed, semi-transparent pellicle mirror instead of a

moving mirror. Later special Canon models used similar mechanisms to achieve

such speeds, while cameras with moving mirrors reached approximately 5 frames

per second by the 1980s. Today, the fastest professional models from Canon and

Nikon achieve approximately 10 frames per second with a moving mirror.

In the digital camera era, some users continue to refer to continuous

shooting modes as "motor drive". Many camera models refer to different shooting

modes—single shot, burst, continuous, self timer—as drive modes, thus keeping

alive the terminology of film. An external battery grip is occasionally referred to as

a motor drive as it tends to increase the frame rate.
