EXPERIMENTAL STUDY ON TUBE JAMMING THROUGH A WEDGE-SHAPED HOPPER
Bibliographic record
Abstract
A wedge-shaped hopper is frequently utilized as a tube feeder in the electric heater process. When falling from a wedge-shaped hopper, the tubes often form an arch near the outlet and stop the feeding process since a pile of tubes pass through a small hopper outlet one by one. This research aims to investigate the effect of process factors on the tube feeding process by applying Taguchi’s method and to design a wedge-shaped hopper that never jams. Chosen process factors are the wall angle of the hopper, outlet width of the hopper, number of test tubes, vibration strength of the vibrators and tube materials. Experimental results show that a large wall angle, a wide hopper outlet, a few tubes and a weak vibration are optimal settings. The wall angle and the outlet width of the hopper are more influential to reduce the jamming for all tube materials. A hopper that hardly jams can be designed by using optimum conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
