  • the bag feed is effected in such a way that a number of bags are superposed in a bag reservoir and then one sheet of bag is raised vertically by a first pneumatic adsorption means, that the raised bag is carried by a second turnable adsorption means to a position confronting to an outlet of the filling spout, thereafter a valve inlet of the bag is embraced by a third pneumatic adsorption means to open the bag inlet for insertion to the filling spout of the packaging apparatus thereby ensuring a continuous and quick feeding of numerous bags with stable operation.
  • a principle object of the present invention is to provide an automatic bag feeding apparatus which comprises a reservoir for superposing a number of bags therein, a first pneumatic adsorption means for raising one sheet of bag vertically, a second pneumatic adsorption means for transferring raised bag to a position confronting to an outlet of the filling spout of the packaging apparatus and a third pneumatic adsorption means for opening an inlet of the bag for insertion to the filling spout of the packaging apparatus.
  • FIG. 1 is a block diagram of-the bag feeding process in accordance with the present invention
  • FIG. 2 is a plan view of the bag feeding mechanism in accordance with the invention.
  • FIG. 3 is a lateral view of the bag reservoir for receiving a number of bags superposed therein;
  • FIG. 4 is a lateral view of the bag lifting mechanism associated with the bag reservoir
  • FIG. 5 (a)-(d) is a pictorial v-iew illustrative of the operation of opening of an inlet of the bag;
  • FIG. 6 (a)-(d) is a pictorial view illustrative of the operation of opening of the bag inlet according to another embodiment of the invention.
  • FIG. 7 is a pictorial view illustrative of an embodiment of arrangement of the apparatus according to the invention.
  • FIG. 1 the bag feeding process in accordance with the present invention is illustrated by the block diagram.
  • a number of bags having valveinlets are superposed in the bag reservoir.
  • One sheet of bag is then taken up by the first pneumatic adsorption means to raise the bag vertically.
  • the raised bag is transferred by the second pneumatic adsorption means to a position confronting to an outlet of the filling spout of the packaging apparatus.
  • the valve inlet of the bag is opened by the third pneumatic adsorption means while being moved for insertion to the filling spout of the packaging apparatus.
  • the reference numeral 10 designates a bag reservoir in which a number of bags 12, e.g., 200 bags, are accumulatedhorizontally.
  • Air pipes 14, 14 are disposed in abuting relation with the bag reservoir 10 to provide a first pneumatic bag adsorption means 16 which is turnable around a pivot 18 by means of an air-cylinder 20 thereby to raise the bag 12 vertically.
  • the raised bag 12 is carried in suspension by the second pneumatic adsorption means 22 comprising a suction manifold and driven by an electric motor 24 to a position A confronting to an outlet of the filling spout 26 of the packaging apparatus (not shown) wherein an inlet 28 extending along an upper end of the bag 12 is opened by a third pneumatic adsorption means 30 for insertion of the bag inlet 28 to the filling spout 26 after some movement from the position A.
  • the second pneumatic adsorption means 22 comprising a suction manifold and driven by an electric motor 24 to a position A confronting to an outlet of the filling spout 26 of the packaging apparatus (not shown) wherein an inlet 28 extending along an upper end of the bag 12 is opened by a third pneumatic adsorption means 30 for insertion of the bag inlet 28 to the filling spout 26 after some movement from the position A.
  • the third pneumatic adsorption means 30 comprises a pair of suction manifolds 32, 32which are relatively positioned and connected by an air-cylinder 34.
  • the suction manifolds 32, 32 embrace the valve inlet 28 by an actuation of the air-cylinder 34 and are moved toward opposite directions with opening of the bag inlet 28 under the pneumatic adsorption.
  • the third pneumatic adsorption means 30 with suction manifolds 32 hanging the bag 12 is moved toward the packaging apparatus for insertion of the bag inlet 28 into the filling spout 26 of the packer.
  • the bag 12 carried by the second pneumatic adsorption means 22 is dropped into a bag support 36 disposed in parallel with the filling spout 26.
  • the bag support 36 is formed of a single plate which is bent symmetrically to form a U-shaped casing to accommodate the bag 12 in standing so that the bag 12 before insertion into the filling spout is always placed in parallel with the filling spout 26 for enabling a smooth and accurate insertion of the bag inlet into the filling spout.
  • valve type bags preferably available to the process in accordance with the present invention includes symmetrically sewed bag, pasted angular bottom bag, polyethylene film bag, polyethylene film lined or laminated bag. It will be appreciated that when those bags are superposed each top and bottom end portion of the superposed bags has a greater thickness than the middle portion of the superposed bags as best shown in FIG. 3 which disturbs a desired adsorption of the bag by the first pneumatic adsorption means 16 because of the inclined surface of the bag.
