Bag shouldering and deaerating apparatus |
摘要 |
An apparatus for shouldering and deaerating filled bags provides rapid expulsion of excess gas from flexible top-closure bags containing particulate material. The automated apparatus permits completely controlled handling of the filled bags from the filling station through their movement to a bag closing station. The filled bag is transported to the shouldering and deaerating station where a portion of its top edge is clamped and held by upwardly-biased bag grippers while the contents are settled, compacted and degasified by vibration. Pressure rollers mounted on the front and rear of the bag below the bag grippers compressively roll downward to collapse the bag top and expel gas upwardly therefrom. Downward movement of the rollers ceases when indirect contact with the bag contents activates a limit switch or servo mechanism.
