US 4,351,663 A · Glass container rejector

Abstract

A dual-mode takeout mechanism is provided for use in, for example, an individual section glassware forming machine. In the normal mode of operation, the formed ware is transported in a fixed radius vertical arc from a molding station to a cooling station and released for further processing. In the reject mode of operation, defective formed ware is transported in an enlarging vertical arc from the molding station to a disposal station. An arm of the takeout mechanism is capable of extending in telescoping fashion, and is activated in the reject mode so as to begin the extension process as the takeout mechanism begins to transport ware from the molding station. A controller is provided to detect when the reject mode has been commanded. The reject mode can be entered for a desired number of cycles by computer command, sensor command, or operator command (manual entry). If the reject mode has been entered, the controller operates a solenoid controlled valve which extends the arm pneumatically.

Dependent claims

In an individual section of a machine for forming ware having molded means and cooling means for controllably cooling said ware, an apparatus for transporting ware from said molding means to a selected one of subsequent process means, including said cooling means and a disposal means, said apparatus comprising:

a first member, operable arcuately in a predetermined plane, having first and second actuator means;
a third actuator means for operating said first member arcuately in said predetermined plane;
a second member movable lengthwise with respect to said first member, said first actuator means communicating with said second member and operative to extend and retract said second member with respect to said first member;
and
a head member for grasping and releasing said ware, said head member connected to said second member and responsive to said second actuator means for maintaining the axis of said ware perpendicular to a horizontal plane.

In an individual section of a machine for molding glassware, an improved ware transfer apparatus for selectively transferring newly molded glassware (1) to a normal position for cooling and subsequent normal processing or (2) to a reject position for disposal, said ware transfer apparatus comprising:

an arm rotatable about an axis and having a ware pick-up mechanism attached thereto for picking up said ware and normally transporting it through a first arc to said normal position;
and
said arm including a variable length section which, upon actuation, causes said ware to be transported through a second arc to a reject position.

A method for selectively transferring articles, supplied in successive cycles of operation of a machine, to a first area for additional processing and a second area for disposal comprising the steps of:

continuously accumulating the number of disposed operations commanded;
grasping said article;
rotating said article, said article being rotated one hundred eighty degrees through a first vertical arc to said first area when the result of said accumulating step is zero and being rotated one hundred eighty degrees through a second vertical arc to said second area when the result of said accumulating step is non-zero;
releasing said article;
and
adjusting the result of said accumulating step to account for each executed disposal operation.
