Solution Overview
Problem
Existing machining devices with tool changing arrangements face challenges in achieving flexible and independent access to tools while minimizing space requirements, technical complexity, and costs, and reducing tool changing time.
Innovation Solution
The tool changing arrangement is positioned at least partially on a longitudinal side of the guide device, allowing only one side to be designed for spindle unit movement, using a single guide device and tool changing arrangement, which reduces space and cost, and minimizes tool changing time by optimizing tool access and transfer distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two guide devices are provided for two spindle units to access tools independently, then independent access for spindle units is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent merges the tool changing arrangements for both spindle units onto a single guide device. The tool changing arrangement includes a chain changer with tool holders that can service both spindle units from one location, eliminating the need for separate guide devices for each spindle unit while maintaining independent access capability
Solution Approach 2:
The single guide device is designed with universal functionality to serve both spindle units. The tool changing arrangement on the guide device can transfer tools to either spindle unit independently, making the guide device multi-functional rather than dedicated to a single spindle unit
2Loss of time
If tool changing arrangement is positioned on longitudinal side of guide device, then tool changing time is reduced, but space utilization changes
Solution Approach 1:
The patent repositions the tool changing arrangement from traditional end-positioning to longitudinal side positioning along the guide device. This spatial reconfiguration reduces the transfer distance between tool changing arrangement and spindle units, enabling faster tool changes while optimizing the use of available space in the machining device

AI summary
The device (1) has two spindle units (3) movably arranged at a side of a beam-shaped guiding unit (2) e.g. portal. A tool changing unit (4) supplies the spindle units with machining tools and/or processing aggregates (5). The tool changing unit is partially arranged at a long side of the guiding unit. The tool changing unit is upward or downward movably arranged with respect to the spindle units. The spindle units are arranged between the guiding unit and tool changing unit. A transition region (6) transmits the tools from the tool changing unit to the spindle units. The workpieces are made of timber, timber material or plastic material.
