Abstract
In a controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, a distance between the position of the mold body and the position of the product removing unit is determined. It is then judged whether or not the distance is smaller than a predetermined distance. If the distance is smaller than the predetermined distance, the operation of product removing unit is decelerated or stopped.
Claims17
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a predetermined distance;
- and
- speed control means for decelerating or stopping an operation of said product removing unit if it is judged by said judging means that said distance is smaller than the predetermined distance during a mold opening operation,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a first and a second predetermined distances;
- and
- speed control means for decelerating an operation of said product removing unit if it is judged by said judging means that said distance is smaller than the first predetermined distance, and for stopping the operation of said product removing unit if it is judged that said distance is smaller than the second predetermined distance that is smaller than the first predetermined distance, during a mold opening operation,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a predetermined distance;
- and
- speed control means for decelerating or stopping a mold closing operation if it is judged by said judging means that said distance is smaller than the predetermined distance during the mold closing operation,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a first and a second predetermined distances;
- and
- speed control means for decelerating a mold closing operation if it is judged by said judging means that said distance is smaller than the first predetermined distance, and for stopping the mold closing operation if it is judged that said distance is smaller than the second predetermined distance that is smaller than the first predetermined distance, during the mold closing operation,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a predetermined distance;
- and
- speed control means for decelerating or stopping an operation of said product removing unit during a mold opening operation and for decelerating or stopping a mold closing operation during the mold closing operation if it is judged by said judging means that said distance is smaller than the predetermined distance,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between a mold body comprising a mold and a peripheral equipment installed to said mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said mold body and a position of said product removing unit;
- judging means for judging whether or not said determined distance between the position of said mold body and the position of said product removing unit is smaller than a first predetermined distance and a second predetermined distance;
- and
- speed control means for decelerating an operation of said product removing unit during mold opening operation and for decelerating a mold closing operation during the mold closing operation if it is judged by said judging means that said distance is smaller than the first predetermined distance, and for stopping the operation of said product removing unit during the mold opening operation and for stopping the mold closing operation during the mold closing operation if it is judged that said distance is smaller than the second predetermined distance that is smaller than the first predetermined distance,
- whereby interference between said product removing unit and said mold body is avoided.
A controller for avoiding interference between an ejector which ejects a molded product from an opened mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said ejector and a position of said product removing unit;
- judging means for judging whether or not said distance between the position of said ejector and the position of said product removing unit is smaller than a predetermined distance;
- and
- speed control means for decelerating or stopping an ejector operation if it is judged by said judging means that said distance is smaller than the predetermined distance during ejector operation,
- whereby interference between said ejector and said product removing unit is avoided.
A controller for avoiding interference between an ejector which ejects a molded product from an opened mold and a product removing unit in an injection molding machine, comprising:
- means for determining a distance between a position of said ejector and a position of said product removing unit;
- judging means for judging whether or not said distance between the position of said ejector and the position of said product removing unit is smaller than a predetermined distance;
- and
- speed control means for decelerating or stopping an operation of said product removing unit if it is judged by said judging means that said distance is smaller than the predetermined distance during the time when an ejector operation is stopped,
- whereby interference between said ejector and said product removing unit is avoided.
