Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for taking out molded products face challenges in quickly suppressing displacement vibration and require versatile vibration control, which is difficult to achieve with traditional dynamic vibration absorbing devices, especially in constrained spaces with heavy attachments.
Innovation Solution
An apparatus incorporating a positioning servomechanism, movable bases, approach frames, and an active vibration suppressing system using electromagnetic actuators to control displacement vibrations, allowing for efficient suppression by amplifying vibration through the weight of movable bases and leveraging principles to apply vibrations in phase with or delayed from the attachment's displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a large powerful electromagnetic actuator is used to quickly suppress vibration of a heavy attachment, then the vibration suppression speed and effectiveness improve, but the device size increases and may collide with surrounding objects in constrained spaces
Solution Approach 1:
The patent divides the vibration suppression function into two parts: a small electromagnetic actuator mounted on the attachment for direct vibration suppression, and a larger actuator mounted on the movable base for providing amplifying vibration. This segmentation allows the use of a small actuator on the attachment (avoiding space constraints) while still achieving effective vibration suppression through the amplifying effect of the base actuator.
Solution Approach 2:
The patent introduces the movable base as an intermediary between the large actuator and the attachment. The base actuator generates amplifying vibration that is transmitted through the approach frame to the attachment, indirectly suppressing attachment vibration without requiring direct mounting of a large actuator on the attachment itself.
2Manufacturing precision
If individual dynamic vibration absorbing devices are prepared for each take-out condition, then the vibration suppression precision improves, but the device complexity and lack of versatility increase
Solution Approach 1:
The patent employs dynamic vibration suppression control that actively adjusts the vibration characteristics based on real-time detection of attachment vibration. The control unit generates control signals that dynamically modify the actuator operation to counteract detected vibrations, allowing the system to adapt to varied take-out conditions without requiring individual devices for each condition.
Solution Approach 2:
The patent implements a feedback control system where vibration detection means continuously monitors attachment vibration and feeds this information back to the control unit. The control unit then adjusts the actuator operation based on this feedback to suppress the detected vibrations, enabling versatile adaptation to different take-out conditions while maintaining high suppression precision.

AI summary
There is provided an apparatus for taking out a molded product, the apparatus being capable of suppressing displacement vibration of an attachment mounted at a leading end of an approach frame by means of active control using an electromagnetic actuator that has necessary power. One or more electromagnetic actuators are disposed at a portion of the approach frame, positioned opposite to the attachment with respect to a movable base. An active vibration suppressing system suppresses the displacement vibration of the attachment by causing the one or more electromagnetic actuators to generate a vibration in the same phase as the displacement vibration of the attachment.
