  It should be noted that the air cylinder 44 of the right fifth shutter mechanism 34 and the air cylinder 49 of the left fifth shutter mechanism 39 maintain the same state and are alternately placed on the right secondary accumulation shutter 54 and the left secondary accumulation shutter 59. The stacked packaging bags FX1 and FX2 are held.

  Next, when the left inclined shutter 56 is opened by being driven so that the air cylinder 46 of the left second shutter mechanism 36 is retracted, the packaging bag FX3 falls down on the right holding shutter 52 of the right third shutter mechanism 32 and becomes horizontal. Become posture. In FIG. 11, the time until the packaging bag FX3 is in the horizontal posture is already inclined by 45 degrees at the time of starting, so it may be half of the time for changing from the conventional vertical posture to the horizontal posture. The device can be operated at high speed.

  Then, when the left inclined shutter 56 in FIG. 11 is opened, the push-down rod 61 of the lower cylinder 60 is driven downward, thereby speeding up the fall of the packaging bag FX3 inclined 45 degrees. When the packaging bag FX3 is easy to collapse, that is, when the packaging film is hard and the weight of the entire bag is heavy, the packaging bag FX3 can easily fall down simply by opening the left inclined shutter 56. There is a case in which an operation in which the push-down rod 61 of the cylinder 60 is not driven downward is set. That is, the drive control of the push-down bar 61 of the lower cylinder 60 is selected according to the finished form of the packaging bag made by the rotary automatic packaging machine.

  Further, in FIG. 11, the packaging bag FX4 conveyed next to the packaging bag FX3 is guided to the right inlet 65 of the charging mechanism 22 and is in a state immediately before dropping, whereas it is opened in FIG. In order to close the holding shutter 55, the air cylinder 45 of the left first shutter mechanism 35 is driven to push out.

  Thereafter, the stacking apparatus 20 repeatedly performs the operations from FIG. 6 to FIG. 11 while holding the packaging bags FX1 and FX2 stacked alternately on the fifth shutter mechanisms 34 and 39, and thereby performing the fifth shutter mechanism. It moves so that the next packaging bag may be piled up on 34,39.

  When the number of stacks set in the stacking device 20 is an even number, the set number (even number) is stacked on the fifth shutter mechanisms 34 and 39 by dropping from the fourth shutter mechanisms 33 and 38 two by two. If the stacking number set in the stacking device 20 is an odd number, the second shutter mechanism 33, 38 is dropped two by two, and the fourth shutter mechanism 33, 38 has the last stacking number as one, and the fifth shutter mechanism 34 , 39 is accumulated on the set number (odd number).

  That is, in order to collect odd numbers, it is necessary to drop one from the fourth shutter mechanisms 33, 38 at least once. On the other hand, the operation of dropping one from the fourth shutter mechanisms 33, 38 causes the horizontal balance of the packaging bag. May be disturbed. For this reason, the second shutter mechanism 34, 39 has been accumulated two by two, and the fourth shutter mechanism 33, the fourth shutter mechanism 33, 38 and the fifth shutter mechanism 34, 39 have the minimum drop distance. Control is performed so that one drop occurs in the last 38 stacking operations. When the accumulation in the fifth shutter mechanisms 34 and 39 reaches a predetermined number set in advance, the fifth shutter mechanisms 34 and 39 are opened, and the packaging bags accumulated on the belt conveyor 70 directly below are dropped, and one accumulation is performed. The operation is complete.

  Thus, as described in the description of the operation of the present invention in FIGS. 3 to 11, a plurality of air cylinders are combined to form a driving mechanism for the stacking operation. It is possible to provide a packaging bag stacking device that can be simplified and can be manufactured at a low cost and at the same time increase the stacking speed.

  The embodiment of the present invention is an example for embodying the present invention, and has a corresponding relationship with the invention-specific matters in the claims, but is not limited thereto. Various modifications can be made without departing from the scope of the invention.
