摘要:
A method and device for opening spout attachment portion of a bag being set up such that films on both sides of a spout attachment portion (2) of a bag (1) are suction-held up by a pair of suction cups (8), and the spacing between the pair of suction cups is widened to open the spout attachment portion, after which a gas is blown from the spout attachment portion into the bag by a gas blowing member (9); and when the gas is blown into, a clamping member (19) clamps a position under the gripper that is on the top edge (6) side of the bag from both sides of the bag, thus suppressing outflow of the gas blown into the bag from the top edge, thus allowing entire bag to inflate for its entirety substantially and the spout attachment portion to be kept opened.

A bag-making and packaging machine including first through third transportation devices (4, 5; 21, 22; 35) provided between a positioning conveyor (3) that positions bags (6a, 7a, 6b, 7b) fed out from a horizontal-type bag-making machine (1) and a supply conveyor (39) that supplies the bags ( 6a, 7a, 6b, 7b) to a conveyor magazine-type bag-supply apparatus of a packaging machine, wherein the first transportation device (4, 5) suctions and raises the bags ( 6a, 7a, 6b, 7b) from the positioning conveyor (3) and changes them into a vertical attitude with the bag mouth portions facing downward, the second transportation device (21, 22) takes the bags ( 6a, 7a, 6b, 7b) held by the first transportation devices (4, 5) by gripping them with the gripping members (27), horizontally transports them to a prescribed position while rotating them, and then the third transportation device (35) suctions and takes up the bags ( 6a, 7a, 6b, 7b) from the second transportation device (21, 22), changes them to a horizontal attitude with the bag mouth portions facing in the bag feed direction and then places them on the supply conveyor (39).
摘要:
A rotary-type bag transfer device including a plurality of pairs of left and right grippers (2) provided around an intermittently rotating table (1). A first support shaft (8) and a second support shaft (9) are provided on the base portion of each of the arms (5) of the grippers. A first link (14) linked at its one end to the table and pivotable horizontally is linked at another end thereof to the center of a second link (15), the second link is linked at one end thereof to the first support shaft, and a sliding member (21) installed at the other end of the second link is provided to slide in a slot (22) formed in the table. The slot is parallel to a reference plane (N). A restricting link (24) linked at one end to the table is linked at another end to the second support shaft.
摘要:
A packaging system including two rotary tables (5, 6) provided adjacent each other on a common base (1) and connected to a common drive source to intermittently rotate in mutually opposite directions in the same intermittent indexing mode. For the rotary tables (5, 6), empty bag supplying devices (10, 11), mouth-opening devices (14, 15), packaged material filling devices (16, 17), mouth-sealing devices (22, 23), and product bag unloading devices (8, 9) are respectively provided on the base (1). The product bag unloading devices (8, 9) are disposed adjacent each other in the vicinity of the most proximate stop positions (H, h) of the tables, and the empty bag supplying devices (10,11) are disposed adjacent each other in the vicinity of the following stop positions (A, a).
摘要:
A horn 39 and an anvil 49 are moved toward and away from each other by axially reciprocating a driving rod 29 and thereby reciprocatingly rotating a forked lever 31 in a predetermined angle range. The horn and the anvil are moved toward and pressed against each other with a predetermined force with a bag mouth b held therebetween. A sensor 61 detects the position of a second mounting block 53 secured to the rear end of a sliding shaft 47 of the anvil, thereby detecting the distance between respective pressing surfaces 40 and 50 of the horn and the anvil, i.e. the thickness m of a portion of the bag mouth held between the pressing surfaces 40 and 50. When the thickness m is not less than a predetermined threshold value M, a vibrator 35 is activated to perform sealing. When the thickness m is less than the threshold value M, no sealing is performed.
摘要:
A method and apparatus for charging the gas compartment portion of a bag (1) in which incisions (9) are formed in gas introduction section (6a) of the gas compartment portion (6). A pair of gas injection nozzles (23, 24) 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 (23a, 24a) 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.
摘要:
A filling channel opening and closing device, which is used in a liquid product filling apparatus, including an opening and closing control unit (3) that includes a flexible tube (7) and a chamber (8) enclosing the flexible tube (7) in a gastight manner, a gas supply and exhaust means that collapses and restores the flexible tube (7) by supplying pressurized gas into the chamber (8) and exhausting the gas from the chamber (8), and a control means (6) that controls the timing of supply and exhaust of the gas of the gas supply and exhaust means (34, 35).
摘要:
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 (1) mounted on the intermittently rotating table, gripper arms (2) affixed to the swing levers (1), chuck sections (3) installed in the tip end portions of the gripper arms (2), and chuck open/close mechanisms (4) that open and close the chuck sections (3). Gripper arms (2) are cylindrical, and air cylinders (11) and link mechanisms (13) that constitute the chuck open/close mechanism (4) are installed inside tube bodies of the gripper arms (1).
