Title
(EN) APPARATUS FOR PLACING MOLD CHARGES INTO A COMPRESSION MOLDING MACHINE
(FR) APPAREIL POUR PLACER DES CHARGES DE MOULE DANS UNE MACHINE DE MOULAGE PAR COMPRESSION
Abstract
(EN)
An apparatus for placing a mold charge (532) into a mold (52) of a compression molding machine includes a carrier (500) mounted for rotation around a first axis, at least one arm (506) mounted on the carrier for rotation around a second axis at an angle to the first axis, and a mold charge pick-up cup (518) on the arm for receiving a mold charge, transporting the mold charge and placing the mold charge into a mold of the compression molding machine. A cam (528) is carried in stationary position adjacent to the carrier surrounding the first axis, and a cam follower (524, 526 or 602 or 632) is operatively coupled to the arm in engagement with the cam for rotating the arm and the mold charge pick-up cup around the second axis as the carrier is rotated around the first axis. The second axis of rotation of the arm preferably is perpendicular to the first axis of rotation of the carrier, and the cam and follower preferably are such that the mold charge pick-up cup is oriented horizontally to receive a mold charge and oriented vertically to deposit the mold charge in the mold of the compression molding machine. A control valve (550) preferably is carried for selective application of vacuum and air under pressure through a passage in the arm to the mold charge pick-up cup to assist in pick-up, transport and deposit of the mold charge into the mold.
(FR)
L'invention porte sur un appareil pour placer une charge de moule (532) dans un moule (52) d'une machine de moulage par compression, l'appareil comprenant un support (500) monté pour une rotation autour d'un premier axe, au moins un bras (506) monté sur le support pour une rotation autour d'un second axe à un angle par rapport au premier axe, et un récipient de récupération de charge de moule (518) sur le bras pour recevoir une charge de moule, transporter la charge de moule et placer la charge de moule dans un moule de la machine de moulage par compression. Une came (528) est portée en position immobile adjacente au support entourant le premier axe, et un galet de came (524, 526 ou 602 ou 632) est couplé de manière opérationnelle au bras en engagement avec la came pour faire tourner le bras et le récipient de récupération de charge de moule autour du second axe lorsque le support tourne autour de premier axe. Le second axe de rotation du bras est, de préférence, perpendiculaire au premier axe de rotation du support, et la came et le galet de came sont, de préférence, tels que le récipient de récupération de charge de moule est orienté horizontalement pour recevoir une charge de moule et orienté verticalement pour déposer la charge de moule dans le moule de la machine de moulage par compression. Une soupape de commande (550) est, de préférence, portée pour appliquer de manière sélective du vide et de l'air sous pression à travers un passage dans le bras vers le récipient de récupération de charge de moule pour aider à la réception, au transport et au dépôt de la charge de moule dans le moule.
