SYNOPSIS ON Rotating Inventory store


Rotating Inventory store

Objective and Methodology used:

Inventory store system which Occupies Less Space and with Security.

Introduction and Working. Methodology behind the project is sprocket gear used to move inventory material boxes platform up and Down

Introduction and Working Of Project

In this project we will make rotating Inventory material storage system. In this project there will be multiple place of for inventory material to be placed on chain system . Our purpose is to place multiple inventory material which are being used in by the customer very often in small space and make inventory storage system reliable and secure.

We will use few sensors for Inventory storage materials slots identifications. There will be keyboard to enter the number of platform come down on Ground floor. We will gave 1, 2 3 numeric names to different floors. When any body enters particular no. key , only then related to that number , particular platform will come down.

Components used:

  • Sprocket Gears

  • Welding Set

  • Cutters

  • grinding wheels

  • Angle 1.5 inch 3 mm 20 feet

  • Chain with special hole ¾ inch pitch

  • Sheet metal

  • Wire 3 mm 3 feet

  • Sheet 3 feet x 3 feet

  • Working:

    The inventory material slots are connected with keyboard buttons with some additional circuitry. We are using sensors over here which will detect the particular material store slot and after that with the help of dc motor the required inventory material slot will come down. Dc motor is attached with sprocket gears and chain mechanism. So whenever we will supply voltage to the dc motor it will starts rotating, so the inventory material slots. The particular button which is being pressed for the required inventory slot will come down.We can fetch out the required material from it.

    Component Description


    Here in this project we use slow speed dc motor with gear box to reduce the speed of the platform. This type of gear motor is getting from the second hand machine. Supply voltage of this dc motor is 6 to 9 volt dc. As we vary the voltage speed is also vary. Current consumption of dc motor is 200 ma. It is also possible to use a stepper motor. If we use stepper motor then we require a high current supply. Normal stepper motor require a minimum 1 A power supply.

    A sprocket or sprocket-wheel

    It is a profiled wheel with teeth, cogs,or even sprockets[4] that mesh with a chain, track or other perforated or indented material. The name ‘sprocket’ applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.

    Sprockets are used in bicycles, motorcycles, cars, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc. Perhaps the most common form of sprocket may be found in the bicycle, in which the pedal shaft carries a large sprocket-wheel, which drives a chain, which, in turn, drives a small sprocket on the axle of the rear wheel . Early automobiles were also largely driven by sprocket and chain mechanism, a practice largely copied from bicycles.

    Sprockets are of various designs, a maximum of efficiency being claimed for each by its originator. Sprockets typically do not have a flange. Some sprockets used with timing belts have flanges to keep the timing belt centered. Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.

    Inventory material storage slots:

    It is made up of metal. We are making square slots for keeping the inventory material in these slots. Which will rotate up and down. When ever we require the particular material we will press the button for the same slots and it will come down. Now we can fetch the required material from that particular store. In next turn we will press the button for another material and the concerned material slot will come down. And we can take the required material from it as well.


    1. For automation in industry carrying raw material like machines, machines parts, inventory material.

    2. In building material industry for carrying cement etc.

    3. For lift purpose

    4. For automatic car parking as well


    • Low cost

    • Reliable

    • Portable

    • Flexible

    • Easy to use- system is very easy to understand

    • Secured system like wallet Parking
