Method and apparatus for assembling aerosol valve

An apparatus for assembling the aerosol valve made up of a number of components comprising valve body with a central hollow wherein disposed are a spring and a stem, a sealing disk formed from a resilient material which has the central bore and is disposed on said stem and said valve body, a valve cap with a central aperture and the hollow, the diameter of said aperture exceeding that of the bore of said sealing disk and said hollow accommodating said sealing disk and the top portion of said valve body;

• said valve cap is rigidly attached to said valve body by deforming the valve cap:
• comprising:
• a plurality of vertical holders each adapted for forming thereon from said components of the valve the first "sealing disk-valve cap" set in a sequence, spaced equidistantly apart and travelling over an endless horizontal path:
• each of said vertical holders provided with a vertical bushing with a central opening and an extensible pin flush-fitted in the opening of said bushing;
• a pin of said holder adapted to enter the bore of said sealing disk while being extended from the bushing of said holder and align said sealing disk through the intermediary of said bore;
• a bushing of said holder adapted for accommodating thereon said sealing disk aligned with the aid of the pin of said holder;
• a means of placing said sealing disk on the pin of said holder;
• a means of placing said valve cap on said sealing disk accommodated on each said holder;
• a plurality of vertical receptacles with through holes each adapted for forming therein from said components of the valve the second "valve body-spring-stem" set in a sequence, spaced equidistantly apart and travelling over an endless horizontal path;
• a means of placing said valve body, hollow upwards, into each said receptacle;
• a means of fitting said spring into the hollow of said valve body accommodated in each of said receptacles;
• a means of placing said stem on said spring accommodated in the hollow of said valve body;
• at least one means of gripping said first set disposed on said holder, said gripping being performed from the top by entering the bore of said sealing disk through the aperture in the valve cap, and transferring said first set so that its original orientation is retained into a position coaxially with said second set by placing said first set above said second set;
• said means of gripping made in the form of a gripper, reciprocating vertically so as to carry out said gripping from the top and horizontally so as to cope with said transferring;
• said gripper provided with a tip at its lower end adapted to pass freely through the aperture in said valve cap and fit with an interference fit with said sealing disk;
• at least one means of bringing said first and second sets together so as to place all said components into the specified position relatively to each other in the valve, said means being given the form of a combination comprising;
• said gripper;
• a vertical reciprocating pushing contrivance adapted to lift said second set in said receptacle;
• at least one means of interlinking said valve cap with said valve body by deforming the valve cap so as to assure the assembling of all the components of the valve into a single structure,
• said last-named means being given the form of a squeezing device incorporating several squeezing elements which move radially at a common horizontal level for coping with said interlinking.
