Panel Drilling Machine Pushing Mechanism for Non-Rectangular Contours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling machines for panels made of wood or plastic face interference issues between pushing members and drilling heads, limiting capacity and flexibility, and are only suitable for rectangular panels, lacking versatility.
Innovation Solution
The drilling machine features a feeding unit with adjustable pushing members and drilling heads that can move between rest and operating positions, allowing for flexible engagement with various panel contours, including non-rectangular shapes, without interfering with the drilling heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pushing members are arranged in their raised operating positions, then the panels can be pushed forward through the drilling station, but the pushing members interfere with the drilling head during forward movement
Solution Approach 1:
The pushing members are designed to be movable between a raised position and a lowered position. During the drilling operation, they lower to clear the drilling head's path, and raise again to engage the panel for forward pushing. This dynamic adjustment eliminates interference while maintaining feeding capability.
2Ease of manufacture
If the pushing members are fixed in position, then the structure is simpler, but the machine can only correctly move panels having a rectangular lateral contour
Solution Approach 1:
The pushing members can move in the second direction (transversal direction) in addition to moving forward. This allows them to adapt their position to match different panel shapes and contours, enabling the machine to handle non-rectangular panels while maintaining structural simplicity through guided motion.
Solution Approach 2:
The pushing members are designed with dual functionality: they can push panels forward along the base and simultaneously adjust their transverse position to accommodate different panel shapes. This multi-functionality allows a single structure to handle various panel types.
3Adaptability or versatility
If the pushing members are made movable in the second direction, then the flexibility and versatility increase, but the device complexity increases
Solution Approach 1:
The pushing members are guided to move along predefined paths on the slides, converting complex multidirectional motion requirements into simpler guided movements. This reduces the overall system complexity while maintaining adaptability.

AI summary
In a drilling machine to drill holes into panels (2) made of wood, plastic or the like, each panel (2) is moved forward through a drilling station (8) using two pushing devices (14) facing each other in a forward direction (6) of the panel (2); each pushing device (14) has a slide (15) mounted transversely to the forward direction (6) and two pushing members (16; 21) distributed along the slide (15) and coupled to the slide (15) so as to be moved, in relation to the slide (15), in the forward direction (6).
