Abstract
A vertical deflashing machine for removing the flashing from blow molded, plastic objects such as containers. The machine has one or more object supporting cavities which support an object to be deflashed in a vertical position. While the object is being supported, a cutting plate moves through the object supporting cavities and strikes and cuts off the flashing affixed to the object. The object remains in a vertical position.
Claims10
A vertical deflashing machine for removing the flashing from blow molded, plastic objects such as containers, said machine comprising:
- a frame having a generally horizontal conveying surface held thereon, said conveying surface having a first side and a second side;
- an object to be deflashed, said object being carried on said conveying surface, and said object having a first side and a second side;
- a first deflashing nest supported by said frame and positioned on the first side of said conveying surface;
- a second deflashing nest supported by said frame and positioned on the second side of said conveying surface;
- a horizontally, movable, deflashing tooling cutting plate supported by said frame on the first side of said conveyor belt;
- means for moving said first and second deflashing nest inwardly at the same time toward said object to be deflashed, said means comprising first and second pulleys on a driven shaft, said first pulley having belt means thereon which drives a first driven pulley and said second pulley having belt means thereon which drives a second driven pulley, and said first and second pulleys are interconnected with said first and second deflashing nest to cause them to move inwardly and outwardly;
- and
- means for moving said tooling cutting plate toward said object to be deflashed, said means for moving said tooling cutting plate being independently actuated from said means for moving said first and second deflashing nests.

A vertical deflashing machine for removing the flashing from blow molded, plastic objects such as containers, said machine comprising:
- a frame having a generally horizontal conveying surface held thereon, said conveying surface having a first side and a second side;
- a first carriage held by rail means supported by said frame and positioned on the first side of said conveying surface, said first carriage supporting a deflashing nest first half, said deflashing nest half having a nest with a vertical face for supporting a first side of a vertical object;
- a horizontally movable deflashing tooling cutting plate supported by said first carriage, said tooling cutting plate being horizontally movable from a withdrawn position away from said conveying surface and an extended position toward said conveying surface;
- a second carriage held by rail means supported by said frame and positioned on the second side of said conveying surface, said second carriage supporting a deflashing nest second half, said deflashing nest second half having a nest with a vertical face for supporting a second side of a vertical object;
- a drive shaft termed by a DC servo motor, said drive shaft holding first and second pulleys, said first pulley having belt means thereon which drives a first driven pulley, and said second pulley has belt means thereon which drives a second driven pulley, and said first and second driven pulleys are interconnected with said first and second carriages, respectively, so that when said driven shaft is turned in a first direction, said first and second carriages move inwardly together, and when said driven shaft is turned in an opposite direction, said first and second carriages move outwardly;
- and
- means for horizontally moving said tooling cutting plate toward said conveying surface and away from said conveying surface, said means for moving said tooling cutting plate being independently driven from said driven shaft.
