(E) to (h)). 18 (a) to 18 (d)), in the steady state, as shown in FIGS. 18 (e) and 18 (f), the pouch containers SP are aligned in a line at L / 5 pitch after the container delivery position θ4. It will be conveyed in the state which was done.

  Accordingly, as shown in FIGS. 19A and 19B, the pouch containers SP delivered to the container delivery positions θ1 to θ4 are collected by the transport plate 103 that moves along a predetermined transport path. Adjacent pouch containers SP do not collide with each other, and even if the number of delivery rows of pouch containers SP increases, the moving speed of the container transport plate 86 does not become extremely large. The effect that the SP is hardly damaged is obtained.

In the above-described embodiment, the container transport plate 86 arranged at the L / 5 pitch is moved intermittently at the 4L / 5 pitch. However, the present invention is not limited to this. The arrangement pitch P1 and the movement pitch P2 of
P1 = L × 1 / (N + n)
P1: Installation pitch
L: Distance between adjacent article delivery positions
N: Total number of columns
n: natural number and
P2 = L × N / (N + n)
P2: Movement pitch
L: Distance between adjacent article delivery positions
N: Total number of columns
n may be calculated according to a natural number .

In the embodiment described above, when calculating the arrangement pitch P1 and the movement pitch P2 of the container transport plate, the natural number n in P1 = L × 1 / (N + n) and P2 = L × N / (N + n) is set to 1. However, the present invention is not limited to this, and n can be set to 2 or more. However, it goes without saying that a total number N + n of pouch containers SP must be arranged between adjacent container delivery positions. In particular, when n is 1, as shown in FIGS. 18 (e) and 18 (f), when the steady state is reached, the pouch containers SP are conveyed in a state of being arranged at equal intervals on the downstream side of the container delivery position. When n is 2 or more, the pouch containers SP are not arranged at regular intervals on the downstream side of the container delivery position even when the steady state is reached, and the pouch containers are transported in some missing positions.

  Further, in the above-described embodiment, each container delivery guide rail 71 is fitted to the container delivery guide rail 71 in a state where the end of each container delivery guide rail 71 is fitted in the missing rail portion of one of the container delivery guide rails 81. Although it is connected to the rail 81, the present invention is not limited to this, and as with the pouch container transport device shown in FIG. 19, only the width that allows the pouch container SP to pass through is opened. The guide rail may be divided and each container delivery guide rail may be connected to the outer edge of one of the divided container transport guide rails. In that case, one of the divided container transport guide rails is pressed by moving to the position of the container transport guide rail while the press claw of the container transport mechanism is fitted between the guide rails for container delivery. It will be connected directly through the nails.

  Further, in the embodiment described above, the pouch container SP is sent out in the state where the flat surface of the pouch P is along each of the container sending guide rails 71 in the container sending unit 8. The pouch container SP is transported in a state where the flat surface is orthogonal to the container transport guide rail 81, but the present invention is not limited to this, and the flat surface of the pouch P is not limited to this. The pouch container SP is sent out so as to be orthogonal to each container sending guide rail, and the pouch container SP is conveyed in a state where the flat surface of the pouch P is along the container carrying guide rail in the container carrying-out portion. Is also possible.

  Moreover, although embodiment mentioned above demonstrated the conveying apparatus of the pouch container SP, it is not limited to this, The conveying method and conveying apparatus of this invention are applicable when conveying various articles | goods. Needless to say, it can be done.
