  • the lower bag supplying unit faces and rotates in an opposite direction to that of the upper unit.
  • the lower unit is different from the upper unit in that the second suction pipe 22 is always connected with the vacuum pump so that the bag may be firmly held by the suction pipe when the bag is fitted to the bag receiving bracket.
  • the construction of the bag receiving bracket 30 will be hereinafter described in detail. In FIGS.
  • the reference numeral 25 indicates the second auxiliary suction pipe to draw the bags in the second hopper 26out of the hopper 26, 24 indicates the second arm following the second cam 23 securely mounted on the second shaft 21, and 22 indicates the second suction pipe for bringing the bag to the bag receiving bracket 30.
  • the suction pipes 12 and 22 may comprise a pair of pipes.
  • the auxiliary suction pipes 15 and 25 may also comprise a pair of pipes for more efficient carrying of the bags thereby.
  • a bag holding lever 17 is provided to make it secure to supply the bag in the second hopper to the bag receiving bracket 30.
  • the lever 17 is disposed in the second hopper 26 and presses lightly on the bags in the hopper 26 when the bag is drawn out thereof by the auxiliary suction pipe 25.
  • the bag holding lever 17 is movable up and down as is in the lowermost position in the hopper 26 as shown in FIG. 1 when the auxiliary suction pipe 25 is in its highest position.
  • the lever 17 is associated with coupling arm 18 through coupling levers 19 and 19'.
  • the coupling arm 18 is secured to the shaft of the second arm 24 which is swung up and down in response to the rotation of the second shaft 21, and is swung together therewith. That is, the bag holding lever 17 is moved down in response to the clockwise rotation of the coupling arm 18 accompanying the upward movement of the suction pipe 25 and second arm 24, and is moved up in response to the reverse movement of the above arms and suction pipe 25.
  • the upward movement of the bag holding lever 17 is effected through the levers l9 and 19', and the downward movement thereof is effected by the weight thereof being allowed by the movement of the levers 19 and 19'.
  • the lever 17 While the lever 17 is moved up, the bags are fed into the second hopper from the upper supplying unit and accumulated therein.
  • the lever 17 lightly presses the bags in the hopper 26 to insure that the lowermost bag is drawn out of the hopper 26 by the second suction pipe 25.
  • the bag receiving bracket 30 comprises a base plate 300, a stationary bag receiving plate 31 and a pair of guide plates 32 and 32 mounted on the base plate 300.
  • the guide plates 32 serve to open the mouth of the bag when the bag is supplied to the bracket 30.
  • the bag receiving plate 31 has an upwardly curled tip end 310 to receive the opened mouth of the bag which is opened while the bag is brought to the bracket 30 by the suction pipe 22.
  • the bag is opened by the air blown against the mouth of the bag while the bag is moved down to the bag receiving bracket 30.
  • the brackets 30 are arranged in series on the conveyer to feed the brackets in the direction shown by the arrow in FIG. 2.
  • the bag is received by the receiving plate 31 and its mouth is maintained opened by the guide plates 32 so that the articles to be put therein may be easily inserted thereinto.
  • the article is placed into the bag received on the bracket in the direction shown by the arrow in FIG. 3. If the bag supplying unit as a whole is reciprocated along the direction of the conveyer feed at the same speed as that of the conveyer, then the conveyer can be fed continuously, that is, not intermittently.
  • the guide plates 32 for guiding the article to be inserted into the bag and for making the opening operation easy preferably are swingable so that the bags may be easily opened and the articles may be easily inserted.
  • the guide plates 32 are welded to cylindrical members 34 rotatably mounted on stationary pivots 33.
  • the cylindrical members 34 are provided with projections 35 which are pulled in the direction shown by the arrow by means of springs 36 engaged at the end thereof with stationary pins 37.
  • the pivotal movement of the plates 32 is limited by stoppers 38, and normally the plates 32 are in the position as shown in FIG. 3.
  • the serrated portion 39 of the guide plates 32 prevents the bag from being disengaged from the bracket when the article is inserted thereinto.
  • the shape of the serrated portions 39 should be formed so that the bag may easily received by the bracket and difficult to be disengaged therefrom.
  • the bag supplying device in accordance with the a present invention as described above is operated as follows.
  • the suction pipe opening of the first auxiliary suction pipe 15 is located in the vicinity of the open end of the bags in the hopper 26 so that the mouth of the bags may be opened. Then, the second suction pipe 22 catches the bag at the portion near the open end thereof so that the bags may be easily opened while being brought down to the bag receiving bracket 30.
  • first and second suction pipes 12 and 22 stop at the position where the suction pipes are in contact with the bags at the bottom of the hoppers in order to make the sucking operation effective.
  • the lower hopper 26 several bags, such as ten, are stored normally.
  • the number of the bags to be properly stored in the lower hopper 26 of course depends on the thickness of the bags or unevenness of the bag. That is, the number of the bags stored in the lower hopper can be increased if the unevenness in the thickness of the bags is decreased. This similarly applies to the upper hopper also. Further, it is of course necessary to take the friction coefficient and weight of the bags into consideration.
