FIELD OF INVENTION
This invention relates to a hot casting unloading system.
BACKGROUND OF THE INVENTION
In casting plant, hot casting are around 450 degrees and the ambient temperature is around 55 to 60 degrees. The hot casting are handled manually. The process followed before installation of unloading machine is as follows:
1. First Step: Removal of the casting from the die by a handler, which is dangerous and unsafe.
2. Second Step: Checking of different faces of casting by lifting and turning, which requires lot of efforts.
3. Third Step: Lifting of casting and unloading of the same to the gravity rollers.
The prevalent possible solution to this drawback is to bring the machine from out side which can serve the purpose. However, it is not cost effective.
OBJECTS OF THE INVENTION
The primary object of the present invention is to provide a hot casting unloading system which reduces the fatigue of operator.
Another object of the present invention is to provide a hot casting unloading system which increases the operator's efficiency and safety.
Further object of the present invention is to provide a hot casting unloading system which eliminates manual handling of hot casting.
Yet another object of the present invention is to provide a hot casting unloading system which is efficient.
STATEMENT OF INVENTION
According to this invention there is provided a hot casting unloading system comprising of transfer mechanism and robotic arm wherein the mechanism comprising of LM rail mounted on machined frame in which LM rail is mounted with a plurality of said LM guides to transfer the entire system linearly through a rack and pinion arrangement.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein:

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS;
The present invention discloses a hot casting unloading system comprising of transfer mechanism and robotic arm. Reference may be made to fig. 1 and 2.
The Transfer Mechanism is a system, which transfers the Robotic Arm from Home Position to Machine -1 and back to home position and vice-versa.
This mechanism comprising of:
LM (linear motion) Guides.
LM rails.
Rack and pinion arrangement and
AC Squirrel-cage Motor.
The LM rail is mounted on machined frame made up of Channel wherein LM rail is mounted with a plurality of said LM guides to transfer the entire system linearly through a rack and pinion arrangement. Drive to transfer system is given by an AC Squirrel-cage Motor.
The Robotic arm has two axis comprising of different sub systems which are as follows :-
Z axis Rotation System Y axis Rotation System
Y axis rotation system rotates the entire arm in clock wise and anti-clock wise direction through a motor.
The Z axis rotation system comprising of:
Rack and pinion arrangement: The Rack and Pinion Arrangement is activated through a pneumatic Cylinder to rotate the entire Arm by 180 degrees for casting inspection. Up door mechanism. Down door mechanism.
The Up door and down door mechanism are provided with a plurality of plates and cylinders. The cylinder is activated through an electrical solenoid operated pneumatic valve (5/2) to move the plate forward and reverse. The purpose is to :
Protect the die from burnt sand falling from the casting. Prevent the casting from falling off the catcher during tilt and un-tilt operations.
Operation (Fig. 3)
First Step: The system automatically starts and moves inside the die as the die opens. Thereafter, die ejects the casting, which is held by catcher.
Second Step: The Robotic arm comes out and operator checks the casting without holding it.
Third Step: After completion of checking, operator presses the button so that the system unloads the casting automatically on the Gravity Roller Conveyor.
Advantageous features
It can resist a high temperature up to 600 degrees. It can automatically move inside the machine. It takes the casting out automatically. It rotates the casting for convenience in checking.
It is to be noted that the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:-
