A bag processing system includes: a conveyance mechanism which includes: a plurality of support devices being able to support and release bags; and a conveyance drive device moving the plurality of support devices intermittently; a liquid introduction device which introduces a liquid into the bags supported by the plurality of support devices; and a conveyance control device which controls the conveyance drive device, wherein: the conveyance drive device moves the plurality of support devices in such a manner that the plurality of support devices exhibit same acceleration-deceleration behavior between each other, and the conveyance control device controls the conveyance drive device to accelerate or decelerate the plurality of support devices in such a manner that shaking of the liquid in the bags is reduced.

Bag processing system

A method and apparatus for charging the gas compartment portion of a bag () in which incisions () are formed in gas introduction section () of the gas compartment portion (). A pair of gas injection nozzles () are disposed so as to be on the opposite sides of the bag and reciprocate between its standby and advanced positions, so that in the advanced position, the discharge outlets () of the gas injection nozzles are aligned with the gas introduction section on both sides, and compressed gas is injected into the gas introduction section through the incisions. A small gap (L) is provided between the discharge outlets of the gas injection nozzles when they are in the advanced position. As the gas is injected, film sheets of the expanded gas introduction section closely adhere to the discharge outlets, so that the gas injection state becomes stable.

Gas charging apparatus for a bag equipped with gas compartment portion

In a method and apparatus for filling a gas in a gas compartment portion of a bag, a bag-conveying gripper () including a pair of gripping elements (and), and the inner surface (gripping surface) of the gripping element () being formed with a shallow groove (). The bag-conveying gripper () grips the sealed portion () of the bag, and a neck section () of the gas compartment portion () in the sealed portion is held at a groove formed in the gripping elements of the bag-conveying gripper. Compressed gas is ejected into the gas compartment portion through incision () formed in the neck section, inflating the gas compartment portion. The inflated shape of the neck section held by the bag-conveying gripper is restricted to a flat configuration by the inner surfaces of the bag-conveying gripper.

Gas charging method for a bag equipped with gas compartment

A filling channel opening and closing device, which is used in a liquid product filling apparatus, including an opening and closing control unit that includes a flexible tube and a chamber enclosing the flexible tube in a gastight manner, a gas supply and exhaust device that collapses and restores the flexible tube by supplying pressurized gas into the chamber and exhausting the gas from the chamber, and a control device that controls the timing of supply and exhaust of the gas of the gas supply and exhaust device.

Filling channel opening and closing device for liquid product filling apparatus

A gripper used in, for instance, a bag filling apparatus including a pair of gripper arms provided with chuck holders. Each chuck holder includes first and second tubular portions, first and second tubular members slidably inserted therein, and first and second air cylinders installed within the tubular portions. An inside fixed chuck element is affixed to the tip end of the first tubular member, and an inside movable chuck element is attached to the tip end of the piston rod of the first air cylinder; in addition, an outside fixed chuck element is affixed to the tip end of second tubular member, and an outside movable chuck element is attached to the tip end of the piston rod of the second air cylinder; and the movable chuck elements are opened and closed with respect to the fixed chuck elements by the advance and retreat motions of the respective piston rods.

Gripper for an automatic bag filling apparatus

In an intermittently rotating table type bag filling apparatus, a plurality of pairs of grippers being provided at equal intervals around an intermittently rotating table, the grippers including pairs of left and right swing levers mounted on the intermittently rotating table, gripper arms affixed to swing levers, chuck sections installed in the tip end portions of the gripper arms, and chuck open/close mechanisms that open and close chuck sections. Gripper arms are cylindrical, and air cylinders and link mechanisms that constitute chuck open/close mechanism are installed inside the tube bodies of the gripper arms.

A filling amount adjustment device for a liquid-form substance filling machine, the device including first sliding units disposed on a swing arm and connecting links pivotally attached at one ends to connecting pins of first sliding members (of the first sliding units) that slide along the length of the arm. Second sliding units are disposed on both sides of the swing arm, and the other ends of the connecting links are pivotally connected to the connecting pins of second sliding members (of the second sliding units). Connecting rods connected to piston rods are pivotally connected to the connecting pins. When fine adjustment shafts in which male screws are cut are rotated, the second sliding members are moved and positioned; as a result, the first sliding members slide via the connecting links, thus changing the positions of the connecting pins in the direction of length of the arm.
