As shown in FIGS. 3 to 5, the container guide 4G1 and the container guide 4G2 are adapted to be pressed against the container guide 4G1 as the container P is transported on the capacity adjusting conveyor 4. The conveyance density of the container P on the side (outer circumference side) becomes dense, and the conveyance density of the container P on the container guide 4G2 side (inner circumference side) is coarse when the container conveyance on the capacity adjusting conveyor 4 is coarse. When the container transport on the capacity adjusting conveyor 4 is dense, the container is transported densely, and when the container transport on the capacity adjusting conveyor 4 is in the intermediate state between the dense and rough, A guide shape is formed so as to be in a state.
That is, on the container guide 4G1 side (outward rotation side), the container P is guided in a substantially constant dense state regardless of whether the container conveyance on the capacity adjustment conveyor 4 is dense or rough, and is sent to the conveyance conveyor 5B side.

That is, according to a command from the transport control device 10, if the container transport amount of the line A and the line B is substantially equal, the transport amount of the container to the line A and the line B is set to 4 rows, respectively. If the transport speed of the transport conveyor 6B is adjusted and the container transport amount of the line A is larger than the container transport amount of the line B, the transport container pool amount of the line A increases, so that the transport amount of the container to the line A is reduced. The conveyor speed of the conveyor 6A is adjusted (from 4 rows to 3 rows). On the contrary, if the container transport amount of the line A is less than the container transport amount of the line B, the transport container pool amount of the line B increases. The transport speed of the transport conveyor 6A is adjusted so that the container transport amount to the line A is increased (from four rows to five rows).

Conveying conveyors (16A) 16A (hereinafter referred to as conveying conveyor (16A) 16A) and conveying conveyors (16B) 16B (hereinafter also referred to as conveying conveyors 16A) provided with accumulation amount detection sensors 16AS and 16BS and driven by drive units 16AM and 16BM, respectively. Hereinafter, conveyor 1 (16B) 1 B is also referred to as a transport conveyor 16B), and is connected to the downstream side of the transport conveyor 16A and the transport conveyor 16B, and is transported by a drive unit (not shown) that transports containers to a subsequent process in a dense state. And the capacity transfer conveyor 7B, and the transfer control device 20 that controls the transfer speed of the capacity adjustment conveyor 15A and the capacity adjustment conveyor 15B based on the detection signals of the transfer container accumulation amount detection sensors 16AS and 16BS. .

  The container P filled with liquid by a filling device (not shown) and conveyed from the upstream in the direction of the arrow F passes through the capacity adjustment conveyor 13 driven by the drive unit 13M and is guided by the container guides 13G1 and 13G2. The capacity adjusting conveyor 13 is sent to the capacity conveying conveyor 14 connected adjacently on the downstream side of the capacity adjusting conveyor 13, and the containers P are capacity-conveyed on the capacity conveying conveyor 14 in a dense state. The capacity adjustment conveyor 13 is adapted to adjust the conveyance speed.

It is displayed as the number of transport rows of containers P, and if the containers P are transported in a dense state of 8 rows on the capacity transport conveyor 14, they are guided by the container guides 14G1 and 14G2 and 4 rows to the capacity adjustment conveyor 15B. Thus, the capacity adjustment conveyor 15A is fed in a maximum of 5 rows. That is, the conveyance widths W15A and W15B of the capacity adjustment conveyor 15A and the capacity adjustment conveyor 15B are configured to be 5 rows and 4 rows, respectively, and the conveyance width W15A of the capacity adjustment conveyor 15A is the conveyance width of the capacity adjustment conveyor 15B.
