Printing Support Frame Feeding with Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing systems fail to reliably detect the presence or absence of a support frame in the accommodation section, leading to potential misalignment or incorrect feeding of the support frame between the accommodation rack and the printing device.
Innovation Solution
Incorporation of a first detection section with a sensor to confirm the presence of the support frame, and a delivery device with urethane driving rolls to ensure accurate feeding, along with a weight distribution in the accommodation rack to prevent inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a delivery device is used to feed the support frame between the accommodation rack and the printing device, then the feeding operation can be automated, but the risk of feeding errors increases when detection mechanisms are not implemented
Solution Approach 1:
The patent implements a detection section that senses the presence or absence of the support frame in the accommodation rack and provides feedback to the delivery device. This feedback mechanism allows the delivery device to adjust its feeding operation accordingly, preventing feeding errors while maintaining automation. The detection section monitors the state of the accommodation rack and communicates this information to control the feeding action, ensuring reliable automated operation.
2Ease of operation
If the accommodation rack is designed to be movable between the printing device and the shelf sections, then the support frame can be easily fed in and out, but the rack may become unstable during movement
Solution Approach 1:
The patent introduces a weight component in the accommodation rack to counterbalance the instability caused by movement. The weight is positioned to offset the gravitational force that would cause the rack to tilt or become unstable during feeding operations. This counterweight mechanism allows the rack to move smoothly between positions while maintaining stability, enabling easy support frame feeding without compromising structural balance.
3Device complexity
If a conventional feeding mechanism is used, then the device complexity is lower, but the manufacturing precision and reliability of support frame feeding deteriorate
Solution Approach 1:
The patent replaces conventional mechanical feeding mechanisms with a more sophisticated system that incorporates detection sections and controlled delivery mechanisms. Instead of relying solely on mechanical contact and friction, the system uses sensors to detect the support frame's presence and a controlled delivery device to feed the frame with precise positioning. This substitution of purely mechanical systems with sensor-controlled mechanisms improves manufacturing precision and alignment while accepting increased device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures reliable feeding of the support frame by preventing misalignment and reducing abrasion, thereby enhancing the precision and durability of the printing process.
Implementation Method 1
a delivery device including a feeding section including one or more driving rolls made of urethane, and capable of feeding in or out the support frame in the movement direction by the driving rolls being driven in a state of abutting on the support frame in the accommodation rack
Implementation Method 2
the accommodation rack includes a weight provided such that a center of gravity of the accommodation rack is positioned closer to the printing device than a position supported by the rack support members

AI summary
A printing system includes a printing device, an accommodation rack in which multiple shelf sections accommodate a support frame supporting an exchanging member are provided and the support frame is movable between the printing device and the shelf sections, and which has an opening in a side surface parallel to a movement direction of the support frame, a delivery device including a feeding section capable of feeding in or out the support frame in the movement direction in a state of abutting on the support frame in the accommodation rack, and a moving section causing the feeding section to enter and exit from the accommodation rack through the opening, and an exchange control section including a position sensor configured to detect an entering state of the feeding section and detect that there is no support frame in the shelf sections.
