FIELD OF THE INVENTION:
The present invention generally relates to a sealing machine and more particularly relates to a . three line automatic sealing machine for sealing condom in rectangular shape.
BACKGROUND OF THE INVENTION:
Economy packing of condom is highly necessary for the condom manufacturing process. Speed is required for the same machine to handle more quantity of products and to increase productivity. Initially, manual intervention is required in the process of packaging that might lead to accidents. Productivity of single line packing machine earlier used was low and hence took a long time.to meet the requirements. The machine required manual feeding, which led to occasional accidents. In conventional machines, pre-printed foils are being used for foiling and cam actuated oil dosing is used with plunging mechanism.
In modern machines, highly expensive digital servo controlled traveler units are being used for the purpose of foil and pneumatic actuated dosing with rubber seal pistons are being used. Foil feeding is controlled by a servomotor with complicated control system and sensors. There is a need for system that overcomes above limitation.

The machine is provided with an auto loader system. The auto feeder and dispenser are integrated together.
According to the present invention, the high speed vibratory bowl feeder automatically feeds the condom in the range of 85x3 pcs/min. The condom is squeezed from round shape to oval shape to suit in a rectangular pack by the squeeze mechanism. The oil dosing mechanism ensures no physical damage to the product, during squeezing mechanism. Three line pneumatic operated silicon oil dosing mechanism is employed to ensure accuracy while dosing. The three line rectangular sealing jaw seals the condom using the paper top foil. A counter is used to register the number of packages dispensed. The cutting feature is provided to determine the number of condoms per strip. The temperature controller is provided to limit the temperature of top and bottom rotating jaws. The cutting blade adjuster is integrated, so that chances of accidents are avoided.

DETAILED DESCRIPTION OF THE INVENTION:
Aspects of the present invention described herein, discloses a machine for automatic three line rectangular sealing of condom. The features of the invention will be more readily

understood from the following detailed description when taken in conjunction with the
accompanying drawings.
According to the present invention, the machine consists of a vibratory bowl feeder (1), a three line oil dosing mechanism, a three line squeeze mechanism, a three line foil feeding mechanism, a three line online stamping unit (11), a three line rectangular sealing jaw (4), a pulling mechanism, a counter, a cutting feature, a temperature controller and a panel board. The machine is provided with an auto loader system. The auto feeder (1) and dispenser are integrated together.
The automatic vibratory feeder (1) is developed in the speed at the rate of 85x3 pcs/min with increased productivity. The automatic feeder (1) is able to continuously feed condom automatically without empty gap.
Referring to Fig.3, the oil dosing mechanism (3) includes oil ejection nozzles (7), dozing pump (2) and a tube from dosing pump (6). The dosing mechanism (3) includes a metallic piston arrangement with NRV on both suction and delivery side. The oil ejection nozzles (7) have roughened inner bore to get better control over the drop formation during dozing, that keeps the oil quantity bare minimum.
The three line squeezing mechanism is provided for squeezing the condom from round shape to oval shape to suit in the rectangular pack. The nozzle (7) is used for both forming and dozing at a desired point in the rolled condom.
The three line foil stamping unit (11) includes two rollers (9) & (10) with gears that provide high quality uniform printing. The two rollers (9) & (10) are power free and completely mechanical. One set of gears is used for getting the accuracy and consistency of printing.
The three line rectangular sealing jaw gear and chain drive reduces noise and possesses the ability to seal 4 packets in a line.

A counter is provided to register the number of packages dispensed. The cutting feature is provided to determine the number of condoms per strip. The temperature controller is provided to limit the temperature of top and bottom rotating jaws. The cutting blade adjuster is integrated, so that chances of accidents are avoided.
In the detailed description of the present invention, Condoms are fed in the automatic vibratory feeder (1) moves in a rectilinear track line to squeezing mechanism. The squeezing mechanism forms a round shaped condom into an oval shaped condom. The oil dosing mechanism (3) ensures no physical damage to the product during pushing and ensures no missing and thereby reducing the chances of doubling during squeezing and pushing. High precision pneumatic actuated silicon oil dosing mechanism is used for maintaining accuracy and the electro pneumatically controlled precision dosing helps to excess silicon oil consumption while foil packing. The oval shaped condom is automatically packed by the three line rectangular format sealing jaw. Due to minimum backlash and adopted metallurgy, considerable noise reduction is obtained. Three line pulling mechanism (5) pulls out the three line sealed rectangular condom. The sealed condom is subjected to water leakage checking testing and package seal integrity failure testing.
The advantages of the system includes: (a) high productivity; (b) power saving; (c) work force fully utilized; (d) Quality of operation is improved as automatic feeding of the condom controls monitoring of operation; and (e) Strict compliance to WHO GMP standards due to low human intervention.
