Rotating Product Receiver for Chip-Blocking Machine Tool Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine tools, workpiece chips often enter the product discharge chute, leading to time-consuming chip removal processes, which complicates the operation of machining centers and other machine tools.
Innovation Solution
A machine tool and control method that utilize a rotatable and movable product receiver to control the movement and rotation of the product receiver, allowing it to drop the product into a product discharge chute while keeping the chute opening closed by the receiver, preventing chip entry and improving manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a product discharge chute is provided in the machining chamber to discharge products from the sub spindle, then product discharge function is improved, but workpiece chips enter the chute requiring time-consuming chip removal work
Solution Approach 1:
The product receiver is designed to preliminarily close the chute opening before chips can enter, preventing chip contamination in advance. The receiver moves to the closed position prior to any potential chip entry, eliminating the need for subsequent chip removal operations from the chute
Solution Approach 2:
The product receiver acts as an intermediary element between the machining chamber and the discharge chute. It selectively controls the opening state of the chute, serving as a mediator that allows product passage while blocking chip entry, thereby resolving the contradiction between discharge efficiency and chip contamination
2Ease of operation
If the product receiver is kept open to receive and discharge products, then product transfer is enabled, but workpiece chips can enter the chute during machining operations
Solution Approach 1:
The product receiver is designed with dynamic movement capability, allowing it to switch between open and closed states as needed. It dynamically adjusts its position to be open during product transfer operations and closed during machining operations, thereby enabling product transfer while preventing chip entry
Solution Approach 2:
The product receiver provides localized control over the chute opening state. Rather than keeping the entire chute structure fixed, the receiver locally modifies the opening quality by moving to different positions, creating a selective barrier that allows product passage while blocking chips based on the operational phase

AI summary
A machine tool capable of reducing entry of a workpiece chip into a product discharge chute. A controller controls a receipt of a product made of a workpiece held by a first spindle by a product receiver in a product receiving position, movement of the product receiver to a product dropping position and rotation of the product receiver to drop the product to the product discharge chute through an opening of the product discharge chute, and movement of the product receiver to the product receiving position to receive the product again. A second spindle is kept on standby in the product dropping position during which the opening of the product discharge chute is closed by the product receiver.
