Automatically Timed Kinematic Transport System – Mechanical Project

ABSTRACT
In a continuous assembly factory, there is a need to transfer materials or on process jobs form one working station to the other. In this process, the movement of job from one station to another is accomplished by a belt conveyor system. This system uses an electric drive which is continuous. So the operator does not get sufficient time to complete the operation. Thus the jobs are usually picked and placed on to the work station and the job is processed. This is a tiring and a time consuming job. Also for heavy materials, a separate setup is required for the pick and place operation.
This project proposes the model of a timed transport mechanism. This system uses kinematic linkages for timing the transportation. It uses a four bar mechanism, that follows a coupler curve. It has a greater advantage than the existing system of transport of work piece in a factory.

INTRODUCTION
Material-handling equipment is equipment that relate to the movement, storage, control and protection of materials, goods and products
throughout the process of manufacturing, distribution, consumption and disposal. Material handling equipment is the mechanical equipment involved in the complete system.

Material handling equipment is generally separated into four main categories: storage and handling equipment, engineered systems, industrial trucks, and bulk material handling. Material handling equipment is used to increase output, control costs, and
maximize productivity. There are several ways to determine if the materialhandling equipment is achieving peak efficiency. These include capturing all relevant data related to the warehouse’s operation, measuring how many times an item is “touched” from the time it is ordered until it leaves the building, making sure you are using the proper picking technology, and keeping system downtime to
a minimum. A special analytical data-set known as Stock-keeping units (SKUs) has been devised to aid analysis of materials handling, which is obviously less efficient when a material asset is handled any more than a minimally necessary
number of times.

WORKING PRINCIPLE:

  1. This system uses a four bar mechanism, that follows a coupler curve.
  2. It has a greater advantage than the existing system of transport of work piece in a factory.
  3. The materials are transferred from one work station to another at a specific time interval, which is based on the movement of the linkages.
  4. In a continuous assembly factory, there is a need to transfer materials or on process jobs form one working station to the other. In this process, the movement of job from one station to another is accomplished by a belt conveyor system.
    System uses an electric drive which is continuous. So the operator does not get sufficient time to complete the operation.
  5. Thus the jobs are usually picked and placed on to the work station and the job is processed. This is a tiring and a time consuming job. Also for heavy materials, a separate setup is required for the pick and place operation. This project proposes the model of at imbed transport mechanism.
  6. This system uses kinematic linkages for timing the transportation. It uses a four bar mechanism, that follows a
    coupler curve. It has a greater advantage than the existing system of transport of work piece in a factory.

BLOCK DIAGRAM:
A four-bar linkage, also called a four-bar, is the simplest movable closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage.
If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage.

ADVANTAGES:

  • Electronic control is not required
  • The time required for assembly is greatly reduced.
  • The extra work needed to transfer the work piece from the main transport system to a work station is eliminated.
  • The efficiency of the system is higher as number of friction parts is lesser.
  • The timing of the system can be easily varied based on the application.
  • It is an economic design.

APPLICATIONS:

• Job feeding systems
• Continuous assembly plant
• Packaging industries

One thought on “Automatically Timed Kinematic Transport System – Mechanical Project

  1. Thank you for your help and your articles.
    But,
    What is the input link of this chain?
    Is there a video,showing how it works, available?
    And I appreciate your help.
