|20140102045||Bag Mouth Opening Method And Apparatus For Use In Bag Filling And Packaging - Provided are a bag mouth opening method and apparatus capable of surely and stably opening into a desired shape the mouth of a spout bag having a spout attached to an upper edge-side portion thereof. A spout tilting relative to a bag is corrected into a non-tilting position and pinched with spout pinching members opened and closed by a first air cylinder of a spout holding device. The first air cylinder is held in an initial position in the width direction of the bag by a second air cylinder through a quadric link comprising a connecting rod mounting plate, a connecting rod, a connecting plate, and a second support arm. The interior of the second air cylinder is opened to the atmospheric pressure in synchronism with the start of movement away from each other of a pair of suction cups of a bag mouth opening device and movement toward each other of a pair of gripping members gripping the laterally opposite side edges of the bag. Consequently, the first air cylinder and the pinching members attached thereto become free to move in the width direction of the bag and thus are moved through the bag in accordance with the movement of the gripping members.||04-17-2014|
|20140083061||Method and Apparatus for Manufacturing Spout-Equipped Bags - Method and apparatus for manufacturing spout-equipped bags in which the lateral sides of a bag are gripped by a pair of grippers, the bag is conveyed along a conveying path, and a spout is attached to the bag mouth during the conveyance. Unloading suction members adheres by suction to a bag in a horizontal orientation and takes out the bag; and then bag suction members adheres to the bag and changes the bag into a vertical orientation, the bag is then rotated through a predetermined angle, making the bag mouth horizontal. A transfer chuck grips the bag and conveys it towards grippers, and the bag is displaced a predetermined distance horizontally and supplied to the grippers. The horizontal displacement distance of the transfer chuck is set in advance such that gripping margins on the bag for the grippers are made substantially equal on the left and right of the bag.||03-27-2014|
|20130343857||Conveyer Magazine-type Empty Bag Supplying Apparatus - A conveyer magazine-type empty bag supplying apparatus including an empty bag separator for separating the topmost empty bag from a set of empty bags and feeding it forward, a positioning stopper for the front end of the fed-out empty bag coming into touch therewith, ratchet wheels coming into contact with the empty bag fed by the empty bag separator and feeding the bag forward, causing the bag to come into touch with the positioning stopper, and an empty bag suction members for adhering to and picking up the bag positioned by the positioning stopper. The ratchet wheels are provided on pivoting arms so as to be oscillatingly moved between its delivery position and its retracted position. The delivery position is between the positioning stopper and the empty bag suction members and the retracted position is on the front side which is beyond the stop surface of the positioning stopper.||12-26-2013|

|20130167481||Method for Sealing-in a Gas in a Bag with a Gas Filling Compartment - A method for sealing-in a gas in a bag that has therein a gas filling compartment, including the steps of: placing a blow-out port of a nozzle, which is connected to a pressurized gas supply source, against a cut-in or a hole of the bag and holding the back surface side of the bag with a backing member; blowing a gas from the nozzle into the gas filling compartment of the bag through the cut-in or the hole; gripping and thus closing the gas flow path in sealed portions surrounding the periphery of the cut-in or the hole by a blocking gripper while the gas blow-in continues, thus cutting off the flow of the gas between the cut-in or the hole and the inside of the gas filling compartment; and then sealing the cut-in or the hole, thus allowing the gas to be sealed in the gas filling compartment.||07-04-2013|
|20130125508||Rotary-type Bag Filling and Packaging Machine - A rotary-type bag filling and packaging machine including a synchronized table (||05-23-2013|
|20120240531||Intermittent Transport-Type Rotary Bag Filling and Packaging Apparatus - A rotary-type bag filling and packaging apparatus including a cylindrical hopper installed in a filling position along travel path of bags and gas injection nozzles rotating intermittently with the bags in such manner that interference between the hopper and the gas injection nozzles is avoided and the bags are filled with a material to be packaged while gas injection into the bags is in progress. So as to avoid the interference, the hopper can be comprised of axially separable two pieces so that the two pieces are separated and positioned out of the travel path of the bags and gas injection nozzles and then are moved to the filing position and joined together to form a truncated cone shape so that the bags are filled with the material to be packaged via the truncated cone-shape hopper.||09-27-2012|
|20110318147||Duplex-Type Product Bag Unloading Apparatus - A duplex-type product bag unloading apparatus including two downwardly opening and closing chucks and a chuck-moving mechanism for reciprocating the chucks between positions for receiving and discharging product bags. The relative positions of the two chucks are changed as they are moved from the receiving position to the discharging position by the chuck-moving mechanism, so that in the receiving position, the chucks are arranged in a single row in the bag width direction of the grasped product bags, and in the discharging position, the chucks are in a single row in the thickness direction of the grasped product bags. The chuck-moving mechanism is comprised of a pivot arm and a chuck-supporting frame rotatably mounted to the pivot arm, and the two chucks are rotatably mounted on both sides of the chuck-supporting frame. The chuck-supporting frame and the chucks rotate in synchronism with the pivotal motion of the pivot arm.||12-29-2011|
|20110209441||Standalone Packaging Manipulation Apparatus - A standalone packaging manipulation apparatus performing predetermined packaging manipulation operations on bags being transported along an arcuate transportation path of a rotary-type bag transportation apparatus, the standalone packaging manipulation apparatus including a main arm that pivots and also extends and retracts in a horizontal plane, a sub-arm provided at a distal end portion of the main arm so as to ascend and descend and to rotate in the horizontal plane, and filling nozzle provided on the sub-arm with a predetermined spacing therebetween and simultaneously filling a plurality of bags with liquid. The operation of these elements is performed by mutually independent servomotors.||09-01-2011|
|20110186757||Filling Channel Opening and Closing Device for Liquid Product Filling Apparatus - 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 means that collapses and restores the flexible tube by supplying pressurized gas into the chamber and exhausting the gas from the chamber, and a control means that controls the timing of supply and exhaust of the gas of the gas supply and exhaust means.||08-04-2011|
|20110138751||Bag Filling and Packaging Method and Bag Filling and Packaging Apparatus - In a bag filling and packaging method and apparatus, first and second bag pressing members being provided a specific distance apart in the lengthwise direction of a bag and respectively having pressing components that extend in the width direction of the bag. The bag pressing members are moved toward a rear plate which is provided on the rear side of the bag, so that the pressing component of the first bag pressing member and an end face of the rear plates hold the bag, and the pressing component of the second pressing member pushes a position of the bag above a receiving face of the rear plate, allowing the bag face including the print part to be taut along the receiving face of the rear plate, and printing or print inspection is performed in this configuration.||06-16-2011|
