Function Indicators TRIZ Cases
- Sheet Ejection Tray with Guide Member for Detection Accuracy
A sheet ejection tray uses a guide member to ensure sensor contact during stacking operations.
- Gripping Single-Faced Corrugated Cardboard Sheets
Segmented belt grips clamp flexible single-faced corrugated cardboard edges to prevent damage while maintaining high production speeds.
- Sheet Feeding Cartridge with Movable Restricting Member
A sheet feeding cartridge positions a movable restricting member against the side edge of large sheets to prevent skew during attachment.
- Compact Recording Apparatus Vertical Stacking
A recording apparatus stacks the mounting and receiving units vertically to reduce the occupied space.
- Roll Handling Device for Packaging Machines
An automated roll handling system replaces depleted reels with new ones while verifying rotation direction to maintain continuous packaging throughput.
- Sheet Separation via Local Overpressure on Curved Sliding Surface
A curved stationary sliding surface applies local overpressure through blow holes to separate sheets from a metal transport belt.
- Sheet Separation Nozzle Synchronization for Multi-Feed Reduction
Synchronized lifting and separating nozzles prevent excessive sheet disturbance, reducing multi-feed incidents in image forming apparatuses.
- Sheet Feeding Device Overloading Detection Logic
A sheet feeding device control unit monitors attachment states to determine stacking levels.
- Adjustable Paper Cassette with Sliding Movable Frames
Sliding movable frames adjust the cassette width to accommodate different paper sizes while reducing the image forming apparatus package dimensions.
- Sheet Feeding Timing Control for Image Forming Apparatus
A controller determines feed and delivery request timings based on sheet supplying mechanism type to optimize sheet delivery.
- Web Tension Control via Dynamic PI PID Parameters
A web tension controller adjusts PI or PID parameters using a hyperbolic characteristic curve based on master axis speed.
- Stepwise Sheet Conveyance Speed Control for Misfeed Reduction
A controller increases conveying speed in steps based on detection results to optimize paper feed rates.
- Movable Roller and Cover Mechanism for Jam Clearing
A movable second roller and cover resolve jam clearing difficulties while maintaining foreign matter protection.
- Sheet Stacking Apparatus Obstacle Detection Control
A sheet stacking apparatus detects descending obstacles and halts movement to prevent mechanical damage.
- Pushing Member Alignment for Sheet Trailing Ends
Dynamic stopper positioning stabilizes varying sheet thicknesses to prevent vertical alignment failures in compilation trays.
- Servomotor Pressing Roller Sheet Joining Control
A servomotor replaces pneumatic cylinders to drive a pressing roller, eliminating pressure fluctuations for accurate sheet joining.
- Sheet Feeding Device Dual Lift Plate Level Matching
Dual lift plates in a sheet feeding device adjust their levels via a controller to accommodate long sheets without manual intervention.
- Braking Device for Stacking Value Documents
Cam and eccentric rollers clamp documents against a transport shaft, enabling high-speed stacking while reducing space requirements.
- Reconfigurable Diverter Conveyor Belt Positioning
Adjustable belt ends resolve manual repositioning bottlenecks by enabling accurate lateral spacing of sheet streams without complex mechanical structures.
- Sheet Reversing Mechanism Acceleration Timing for Double-Side Printing
A sheet reversing mechanism calculates preparation time based on transfer speed to synchronize forward and reverse motion.
