Abstract

Servo side shuttle apparatus and method for a molding machine includes structure and/or steps whereby a shuttle plate is disposed adjacent at least one of a first mold half and a second mold half of the molding machine. A guidance assembly is coupled to the mold half and guides the shuttle plate linearly across a molding face of the mold half. A drive mechanism is provided to drive the shuttle plate in a linear direction. An operation structure is coupled to the shuttle plate and is configured to perform an operation on a molded article disposed either in the mold cavity or on the mold core. The operation may include removing the molded article from a mold core, applying a label to a mold cavity, and/or closing the lid of a molded article while it is resident on the mold core.

Claims9

Dependent claims

A molded article work piece application method, comprising the steps of:

driving a shuttle plate only in one or more coplanar linear directions;
applying a work piece to at least one of (i) a molded article resident in at least one of a mold core and a mold cavity, and (ii) at least one of the mold core and the mold cavity, with a work piece application device coupled to the shuffle plate;
removing the molded article from at least one of the mold cavity and the mold core;
and
driving the shuttle plate only in one or more coplanar linear directions to move the work piece application device and the molded article to a work piece and molded article pick up location;
wherein said work piece application device comprises a label application device, and wherein said applying step comprises the step of applying a label to an inside surface of the mold cavity;
said label application device includes a label suction member and an article suction member, and wherein said applying step comprises the step of applying the label with the label suction member;
and
the first driving step drives the shuttle plate in a first direction to (i) move the article suction member to a position adjacent a just-molded article on the mold core, and (ii) move the label suction member, which is holding the label, to a position adjacent the mold cavity, and wherein after the article has been stripped from the mold core, the second driving step drives the shuttle plate a second direction to (iii) move the article suction member to a position to eject the just-molded article from the mold, and (iv) move the label suction member to a position adjacent the work piece pick up location.
