Method of assembling pushbuttons by positioning the bodies in the conveying path
A method of assembling pushbuttons for a liquid dispensing system, in which each pushbutton comprises an actuation body and at least one other component assembled with said body in a given position, said method making provision for using bodies on which a positioning cavity is formed, and continuously supplying a station for assembling the bodies and the other components by means of a path for conveying said bodies, said path having a complementary profile intended to cooperate with the cavities in order to carry out the positioning of said bodies in said conveying path, so as to carry out the assembly of the other components on the bodies thus positioned during their conveying to the assembly station. The invention also concerns an installation for implementing this method, and a pushbutton assembled by implementing said method.
1. A method of assembling pushbuttons for a liquid dispensing system, in which each pushbutton includes an actuation body and a component assembled with said actuation body in a given position, the method comprising:
forming a positioning cavity in the actuation body;
continuously conveying a plurality of the actuation bodies along a path to an assembly station, the path having a complementary profile intended to cooperate with the positioning cavities;
orienting the actuation bodies on the path by having the positioning cavity of each actuation body engage with the complementary profile of the path, wherein the engagement between the positioning cavity of each actuation body and the complementary profile of the path prevents angular rotation of each actuation body on the path; and
assembling the component to the oriented actuation body.
2. The assembly method according to claim 1 ,
wherein the positioning cavity is a notch; and
wherein the orientation step comprises engagement of the notch with a rail extending along the conveying path.
3. The assembly method according to claim 1 , characterised in that the bodies are disposed in the conveying path by vibration.
4. The assembly method according to claim 1 , further comprising the step of expelling from the conveying path the bodies that are incorrectly positioned.
5. The assembly method according to claim 4 , characterised in that the expulsion is carried out by application of a force on a part of the body that projects from the conveying path when said body is in an incorrect position.
