Grand consommateur de canettes, surtout de Coca, ils se dsolent

de voir les botes sorties des distributeurs automatiques,

jetes en vrac la poubelle, une fois consommes.

Notre ide est venue de l. Elle est dabord caractre

environnemental. On pense au recyclage mais aussi limiter

la consommation dnergie.

Recyclage:

lerecyclage des canettescest simple et pratique, tout le monde sy met.Il est la porte de chaque entreprise.Aujourdhui grce aurecyclage des canettesnous conomisons entre autres 75% dnergie et 40% deau. Il est donc primordial pour toute entreprise responsable de se mettre au recyclage de canettes et de se munir dun collecteur ou encore uncompacteur de canettes.

Un compacteur canettes:

Dfinition:

Un compacteur canettes permet la rduction du volume jusqu 20 mm, afin de rsoudre le problme du besoin despace lors du transport des canettes pour les recycler.


7


Fonctionnement:

Cette machine sert rduire le volume dune canette

en lintroduisant dans un orifice, et qui sera par suite comprime par un piston grce un systme pneumatique plus efficace que llectrique et surtout plus rapide.

Lescompacteurs de canettesmanuels sont trs simples utiliser :aprs avoir mis votre canette dans le compacteur vous abaissez le levier et votre canette sera compacte.

Les diffrents types des compacteurs canettes:


Les compacteurs manuels:

Les compacteurs automatiques:


Ce sont des collecteurs automatiss qui trient

et compactent les canettes

Calcul RDM

Pour la vrification de force de pression de compactage on se rfre une tude exprimentale quest base sur un essai, cette dernire consiste comprim une canette.

On remarque que laugmentation de dplacement sera constante, donc on prend la force maximale.
