Vertical Oven Tray Spacing for Thick Panel Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical ovens for drying painted panels are limited in load capacity, particularly for panels thicker than 70 mm, as they require a standard distance between trays that restricts the thickness of panels that can be dried without increasing the oven's footprint or incurring additional costs.
Innovation Solution
The introduction of a parking area within the oven's transit chambers allows for increased tray spacing, enabling the loading of thicker panels by temporarily removing trays from the main path and reinserting them according to a controlled scheme, which can be heated, and utilizing a control unit to manage the drying process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the standard distance between trays is maintained, then the oven footprint remains limited, but the panel thickness is restricted to below 70 mm
Solution Approach 1:
The patent implements a dynamic tray spacing system where the distance between trays can be adjusted based on panel thickness requirements. The conveying system allows variable positioning of trays along the vertical axis, enabling thicker panels (up to 200 mm) to be accommodated by increasing inter-tray distance without expanding the oven's horizontal footprint. This dynamic adjustment resolves the contradiction between handling thicker panels and maintaining a compact oven structure.
2Adaptability or versatility
If trays are continuously moved through the oven, then productivity is maintained, but customization of drying times for different panels is limited
Solution Approach 1:
The patent incorporates a parking area where trays can be temporarily stopped and held before continuing through the drying cycle. This preliminary stopping action allows customization of drying times for specific panels without disrupting the overall continuous flow of the production line. The control system manages this temporarily, enabling adaptability in drying parameters while maintaining productivity through automated sequence management.
Solution Approach 2:
The conveying system implements periodic stopping and resuming of trays at the parking area, creating a rhythmic pattern of continuous motion and temporary halts. This periodic action enables different drying durations for different batches of panels while keeping the production line operating at consistent speed, thus achieving both customization and productivity.
3Length of moving object
If a parking area is added to the oven, then tray spacing can be increased for thicker panels, but device complexity increases
Solution Approach 1:
The parking area is designed as a multi-functional element that serves both as a stopping point for tray spacing adjustment and as an integrated part of the drying chamber. By making the parking area heating-capable and structurally integrated with the existing oven architecture, the patent reduces the need for separate auxiliary systems, thereby limiting the increase in device complexity while achieving increased tray spacing capability.

AI summary
A vertical oven for panels includes trays configured to support mainly flat panels arranged in a multiple of two stacks circulating in opposed directions, such as the first stack moving in an ascending direction and the second stack in a descending direction. The trays are arranged at a distance from each other and the movement of the trays is such that at least one every other tray is withdrawn from the circulation, doubling the distance between the trays.
