TITLE OF THE INVENTION :
An on-line monitoring system for a system for on-line monitoring of an exhaust machine to be used in manufacture of lighting products.
APPLICANTS :
Crompton Greases Limited, CG House, Dr Annie Besant Road, Worli, Mumbai 400 03o, Maharashtra, India, an Indian Company
INVENTOR:
Amin Mukund of Crompton Greaves Limited, Baroda Lamp Works, Kural Village, Padra Jambusar Road, District Baroda- 391430, Gujarat, India, An Indian National
PREAMBLE TO THE DESCRIPTION :
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

Field of the Invention:
This invention relates to the field of automation systems and equipment.
Particularly, this invention relates to an on-line monitoring system for a system for on-line monitoring of an exhaust machine to be used in manufacture of lighting products.
Background of the Invention:
In industries related to manufacture of lighting products such as bulbs, lamps, tubes, and the like, various machines are used. Typically, the steps involved in manufacturing a lighting product may include lamp loading, vacuum exhausting, electrical baking, electrode activation, mercury dosing, gas filling, sealing and lamp unloading.
Typically, an exhaust machine is used to handle the above steps. It is hence, important, that the condition and performance of the exhaust machine be continuously monitored at various physical points, so as to avoid breakdown and faulty product output.
Normally, according to the prior art, for checking the exhaust machine performance in lighting industries, labourers manually write / assign some identification / numbering on the semi-finished lamp. Then, the lamp is loaded in exhaust m/machine in relation to exhaust machine head number. After above said process, lamp is transferred to a conveyor; manually or automatically, where the lamp is passed through Tesla coil. The Tesla coil generates glow inside lamp to check lamp health. Glow

intensity depends on the parameters inside the lamp inside parameter i.e. vacuum level, cleanliness inside lamp, gas pressure and quality, and the like. After this process, pre-numbered lamp is collected manually and results are recorded. This activity requires skilled personnel. There is limited frequency of testing due to time constraint. Normally, this process is done once or twice in an 8 hour span of time.
There is a need for an automated and faster system to check the functioning of exhaust machine.
Objects of the Invention:
An object of the invention is to provide an automated system for checking health of lamps during its making.
Another object of the invention is to provide a reliable automated system for checking health of lamps during its making.
Yet object of the invention is to figure out a faulty lamp from a plurality of lamps during its making.
Summary of the Invention:
According to this invention, there is provided a system for on-line monitoring of an exhaust machine to be used in manufacture of lighting products, said system comprises:

a. first sensor means adapted to sense each of said plurality of gripped
products on said rotating turret of said exhaust machine, in an
incremental manner;
b. counter adapted to increment counter by one as each gripper of the
rotating turret passes through said first sensor and whereby said
gripped product is transferred from said exhaust machine to a testing
setup for testing said product; and
c. display means adapted to display count of said counter, in relation said
gripper being sensed whose gripped product is being tested on said
testing setup, thereby indicating the gripper in case of a fault
indication by said testing setup.
Typically, said system includes second sensor means adapted to sense end of said plurality of grippers on said rotating turret: and a counter adapted to be reset upon sensing input from said second sensor means.
Brief Description of the Accompanying Drawings:
The invention will now be described in relation to the accompanying drawings, in which:
Figure 1 illustrates a schematic of the system.
Detailed Description of the Accompanying Drawings:
According to this invention, there is provided a system for on-line monitoring of an exhaust machine to be used in manufacture of lighting products.

Typically, said system may be retrofitted onto an exhaust machine.
Figure 1 illustrates a schematic of the system.
Reference numeral 100 refers to an exhaust machine.
In accordance with an embodiment of this invention, there is provided an exhaust machine rotating turret (6) having a plurality of heads with lamp grippers (7). Typically, an exhaust machine driving unit (5) drives the rotating turret. The manufactured lighting products or products or lamps (1) which require gas filling are held by the grippers.
Reference numeral 200 refers to a conveyor for receiving manufactured products from said exhaust machine.
In accordance with another embodiment of this invention, there is provided a lamp unloading conveyor driving unit (4) adapted to drive the conveyor so as to receive and unload lamp (1) from said gripper.
In accordance with yet another embodiment of this invention, there is provided a Tesla coil (3) for glowing said lighting product or lamp on the conveyor in order to check its health status to ensure that the gas filing by the exhaust machine has been done properly upon glowing. Tesla coil and conveyor are typically parts of a testing setup.
In accordance with still another embodiment of this invention, there is provided a first sensor means (9) adapted to sense each of said plurality

of gripped products on said rotating turret of said exhaust machine, in an incremental manner. Thus, as each gripper of the rotating turret passes through the first sensor, a counter is engaged to be incremented by one.
In accordance with an additional embodiment of this invention, there is provided a second sensor means (8) adapted to sense end of said plurality of grippers on rotating turret. Thus, the counter shall be reset upon sensing input from said second sensor means.
In accordance with yet an additional embodiment of this invention, there is provided a display means (10) adapted to display count of said counter.
Reference numeral 11 refers to electrical coupling between said sensors and said display means. Reference numeral 12 refers to power supply for said display unit.
Due to this invention, it is possible to monitor each and every lamp coming out from the exhaust machine. Thus, as every lamp is loaded onto the conveyor machine (of testing setup), a corresponding number is displayed on the display. This display corresponds to the gripper which was previously holding the lighting product. In case of faulty lamp, it is easy to identify' the gripper, thereby identifying the cause of error associated with the gripper in relation to said gas filling.
This helps in reducing waste generation and prompt indication of machine condition

We claim,
1. A system for on-line monitoring of an exhaust machine to be used in manufacture of lighting products, said system comprising:
a. first sensor means adapted to sense each of said plurality of gripped
products on said rotating turret of said exhaust machine, in an
incremental manner;
b. counter adapted to increment counter by one as each gripper of the
rotating turret passes through said first sensor and whereby said
gripped product is transferred from said exhaust machine to a
testing setup for testing said product; and
c. display means adapted to display count of said counter, in relation
said gripper being sensed whose gripped product is being tested on
said testing setup, thereby indicating the gripper in case of a fault
indication by said testing setup.
2. A system as claimed in claim 1 wherein, said system includes second sensor means adapted to sense end of said plurality of grippers on said rotating turret; and a counter adapted to be reset upon sensing input from said second sensor means.
