Abstract

L'invention concerne un système de production (2) pour la production en série en particulier de véhicules automobiles. Le système de production comporte une zone d'entreposage de contenants (6) servant à entreposer des contenants, qui contiennent des composants se destinant à la production, une multitude de rayonnages de production (8) disposés de manière éloignée de la zone d'entreposage de contenants (6), desquels des composants peuvent être prélevés des contenants par des opérateurs, et des moyens de transport servant à transporter des contenants hors de la zone d'entreposage de contenants (6) vers les rayonnages de production (8). Les moyens de transport comportent au moins un véhicule à guidage automatique (VGA) (50), sur lequel un rayonnage de transport (52) est disposé et réalisé de telle manière que des contenants peuvent être envoyés ou sont envoyés depuis le rayonnage de transport (52) dans une direction de voyage (direction d'envoi) automatiquement à des rayonnages de production (6). Un dispositif de manutention (52) est disposé sur le VGA et comporte un corps de base (54) et une unité de manutention (56) disposée sur le corps de base (54), laquelle est réalisée pour prélever des contenants du rayonnage de transport (80) dans une direction de convoyage et pour envoyer des contenants à au moins un rayonnage de production (96). L'unité de manutention (56) peut être ajustée linéairement par rapport au corps de base (54) le long d'un premier axe d'ajustement (58) linéaire dans la direction de convoyage; elle peut être ajustée linéairement de manière transversale par rapport à la direction de convoyage le long d'un deuxième axe d'ajustement (60) linéaire; et elle peut être ajustée en hauteur le long d'un troisième axe d'ajustement (62); et elle est reliée de manière à pouvoir tourner autour d'un quatrième axe d'ajustement (64) sensiblement perpendiculaire au corps de base (54).
