Abstract
An intermittently rotating table-type apparatus for manufacturing a bag equipped with spout(s). The apparatus attaches spout(s) to at least one of the mouths of a bag that are at both shoulders of the bag. The mouth(s) of the bag is expanded by bag mouth suction cups, and the main body of the bag is expanded by main body suction cups; and then the spout(s) is inserted in the bag mouth(s), and the inserted spout(s) is held by spout gripping members. When the bag is moved by the rotation of the table, a suction cup arm that supplies suction air to the suction cup and the suction cup are moved to follow the movement of the bag; and after the sealing is made to the bag and spout(s), the arm and the suction cup return to their original positions.
Claims10
A method of manufacturing a bag equipped with at least one spout, in which a supplied bag is gripped by bag-gripping members and intermittently transported along a closed transport path, and manufacturing steps including inserting of a spout in a bag mouth and sealing of the spout and bag mouth are sequentially performed at intermittently different halting positions, said method of manufacturing a bag equipped with a spout comprising the ordered steps of:
- at a spout inserting halting position,
- opening at least one bag mouth by a bag mouth opening means,
- inserting said spout in opened bag mouth,
- gripping the spout, which is inserted into the bag mouth, by spout gripping members and holding the spout at said spout inserting halting position, and
- inactivating said bag mouth opening means, thus releasing the bag mouth , and during that interval expanding a bag body by a bag body expanding means;
- transporting the bag and spout to a spout/bag mouth sealing halting position, with the spout being held by said spout gripping members and the bag body being expanded by said bag body expanding means;
- at the spout/bag mouth sealing halting position,
- executing sealing of the spout and bag mouth, and
- inactivating the bag body expanding means, thus releasing the bag body;
- and
- transporting the bag to a next halting position.
An apparatus for manufacturing a bag equipped with at least one spout in which bag-gripping members that grip a supplied bag are disposed in a plurality of equally spaced groups, said bag-gripping members being intermittently moved a same distance as a spacing of said spaced group along a closed movement path, and manufacturing steps including inserting of a spout in a bag mouth, and sealing of the spout and bag mouth are sequentially performed at intermittently different halting positions;
- said apparatus comprising:
- spout gripping members for gripping at least one spout and holding the spout at a predetermined halting position, said spout gripping members being disposed to correspond to said bag-gripping members and moved intermittently together with said bag-gripping members;
- a bag mouth opening means for opening at least one mouth and a spout inserting means for inserting the spout in the bag mouth, both means being provided at a spout inserting halting position where the spout is inserted in the bag mouth;
- a sealing means provided at a spout/bag mouth sealing halting position where the spout and the bag mouth are sealed together;
- and
- a bag body expanding means for expanding the bag body, said bag body expanding means being provided so as to be movable in a reciprocating manner between said spout inserting halting position and said spout/bag mouth sealing halting position in accordance with a moving configuration that said bag body expanding means moves from said spout inserting halting position to said spout/bag mouth sealing halting position in accordance with a movement of said bag-gripping members and then returns to said spout inserting halting position after sealing of the spout and bag mouth is performed.
