Abstract
An apparatus for engaging and extracting formed articles from an article forming machine is machine mounted adjacent the article forming area and includes a robot in the form of a pivotally connected arm suspended from the mounting and fingers at the free or head end of the arm operative in article engaging and article releasing motions by a cylinder on the fore part of the arm in synchronism with the article forming cycles of the machine. The formed articles are grasped by the fingers, retracted from the forming area, carried to a distant discharge location and released thereat.
Claims2
An article engaging and extracting arrangement for the removal of molded pieces from a molding machine and the deposit thereof at a point apart from the molding machine, the combination of:
- a rotatable and reciprocable driving shaft mounted on the molding machine for retrograde movement with the movable mold in a mold opening direction and for forward movement with the movable mold in a mold closing direction, a cam means fixed on the molding machine for generating a horizontal and rotational movement of the driving shaft responsively to mold opening and mold closing strokes, an extracting arm mounted on and movable with the driving shaft so as to be movable rearwardly with the driving shaft and into the space between the molds in the mold opening mode of the machine and out of the space between the molds and forwardly with the driving shaft in mold closing mode of the machine,
- gripping means responsive to penumatic or hydraulic pressure to open and close in scissor like fashion and carried by the extracting arm and arranged to move therewith in timed relation with the mold opening and mold closing cycle strokes of the molding machine,
- a sequencing mechanism responsive to the cyclic movements of the molding machine for moving the jaws of the gripping means into locking engagement with the article within the machine at the first appropriate moment in the mold opening-closing strokes of the molding machine and for moving the jaws into released engagement with the article outside the machine at the second appropriate moment in the mold opening-closing strokes of the molding machine.
In a press molding machine including a fixed mold and a horizontally movable mold with means for moving the movable mold in linear horizontal directions between mold opened and mold closed positions and with the molds being spaced apart out of engagement when in the opened positions and being in confronting relationship when in the closed positions forming a mold cavity therebetween, the improvement in means for removing a molded article from the space between the fixed and movable means as the machine is moving from a first mold or closed position to a next following mold closed position comprising:
- a driving shaft mounted relative to and movable with the movable mold,
- a cam means sleeved around the driving shaft and mounted relative to and stationary with the fixed mold,
- the driving shaft being imparted a horizontal linear motion and a rotative motion as the movable mold moves in each of mold opening and mold closing directions,
- an extractor arm fixed to the driving shaft and movable linearly and rotatively therewith,
- gripper means pivotally mounted on the extractor arm for grippingly engaging a molded article as the extractor arm is swung rotatively into the space between the molds in the mold opening mode of cyclic operation and swinging the molded article out of the space between the molds in the mold closing mode of cyclic operation.
