Abstract

Apparatus for automatically taking out a molded product, includes an elongated main frame, a laterally movable body supported on the main frame and movable in the longitudinal direction of the main frame, a first drive device for reciprocally moving the laterally movable body relative to the main frame. A frontward-backward movable body is supported on a frontward-backward frame which is connected to the laterally movable body, the frontward-backward movable body being movable in a direction which is substantially perpendicular to the longitudinal direction of the main frame. A lifting device is provided, which includes a drive member connected to the frontward-backward movable body and having a vertically directed axis, a first driven member connected to the frontward-backward movable body and also connected to a rotary member which is rotatably supported on the movable frame. An attachment frame is supported on the movable frame and is movable in a vertical direction. A second driven member is connected to the attachment frame and to the rotatable member. The chuck is connected to the attachment for vertical movement thereof.

Claims

1. Apparatus for automatically taking out a molded product, comprising:

a main frame extending in a lateral direction;

a lateral movable body supported on the main frame;

first drive means for reciprocally moving the lateral movable body in the long direction of the main frame;

a frontward-backward movable body supported on a frontward-backward frame that is coupled to the lateral movable body, the frontward-backward direction being substantially perpendicular to the lateral direction;

second drive means for moving the frontward-backward movable body; and

chuck means for holding a molded product and for moving the molded product to a predetermined position, the chuck means being connected to an attachment frame and having a vertical moving stroke; and

lifting means comprising;

vertical drive means coupled to the frontward-backward movable body and having an axis extending in a vertical direction, the vertical drive means having an axial length one-half the vertical moving stroke of the chuck means;

a first movable frame coupled to the vertical drive means and supported on the frontward-backward movable body, the first movable frame being movable in a vertical direction and having a vertical length one-half the vertical moving stroke of the chuck means;

a pair of pulleys rotatably supported on upper and lower end portions of the first movable frame;

an endless belt trained over the pair of pulleys, the belt having a part coupled to the frontward-backward movable body;

the attachment frame being supported on the first movable frame and movable in a vertical direction, the attachment frame having a part coupled to the belt and having a vertical length one-half the vertical stroke of the chuck means.

2. Apparatus for automatically taking out a molded product according to claim 1, wherein said vertical drive means comprises:

a cylinder having an axis extending in a vertical direction and having an axial length one-half the vertical moving stroke of said chuck means.

3. Apparatus for automatically taking out a molded product according to claim 1, wherein said vertical drive means comprises:

a feed screw rotatably supported on two ends of said frontward-backward frame and having an axial length one-half the vertical moving stroke of said chuck means;

a nut member engaged with said feed screw and coupled to said frontward-backward movable body; and

motor means for rotating said feed screw to actuate said lifting means.
