A conventional container processing apparatus will be described with reference to FIGS.
FIG. 3 is a plan view schematically showing a conventional container processing apparatus.
FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG.
3 and 4, the conventional container processing apparatus 11 is transported in the direction of arrow 4F while being guided by the guide 4G1 and the guide 4G2 by the supply conveyor 4 (the transport speed is 12 m / min as an example). However, the conveyance direction is guided while being guided by an inlet guide (conveyance guide) 7 via a connection plate (dead plate) 16 provided between the supply conveyor 4 and the inlet side of the main conveyor 5. While being supplied to the main conveyor 5 orthogonal to the supply conveyor 4 and being conveyed by the main conveyor 5 in the direction of the arrow 5F (conveying speed is 0.4 m / min as an example), a predetermined amount is supplied from a shower device (not shown). After receiving heat shower water and being heat treated, the main conveyor 5 passes through the connection plate (dead plate) 19 to the discharge conveyor 8. Issued, conveyed is guided over the discharge conveyor 8 to the guide 8G1 and guide 8G2 in the direction of arrow 8F (conveying speed of 12m / min as an example) is configured to gradually be.

The main conveyor 5 is configured such that a flexible conveying body 51 is suspended by a driving roller and a driven roller 52 (not shown), and travels by the driving roller to convey the container P.
Further, guides 5G1 and 5G2 are provided on both sides of the main conveyor 5 so that the containers P conveyed on the main conveyor 5 do not protrude from the main conveyor 5.

As shown in FIG. 4, the connection plate 16 is provided between the supply conveyor 4 and the entrance side of the main conveyor 5 so that the container P can be transferred to the downstream side. Is provided with a guide 16G so that the container P does not jump out.
Although not shown, the connection plate 19 is provided between the outlet side of the main conveyor 5 and the discharge conveyor 8 in the same manner as in the case of the connection plate 16 shown in FIG. Thus, the container P is transferred, and the guide 19G1 and the guide 19G2 are provided so that the container P is guided.

  The operation of the above-described conventional container processing apparatus 11 will be described. The container P is transferred from the supply conveyor 4 to the connection plate 16 while being guided by the inlet guide 7, supplied to the main conveyor 5 side, and conveyed on the main conveyor 5. In the meantime, after being sprayed with shower water of a predetermined temperature from a shower device (not shown), it is transferred to the connection plate 19 and discharged to the discharge conveyor 8.

However, in the technique of the conventional container processing apparatus 11, when the container P is supplied from the supply conveyor 4 to the main conveyor 5 via the connection plate 16, the most downstream side of the supply conveyor 4 as indicated by a broken line A1 in the figure. The container P guided and conveyed by the inlet guide 7 is subjected to a large pressure by being pushed by the dense containers P supplied from the next to the next from the supply conveyor 4, and the container P is damaged. There is a fear that it will end. In particular, when the container P is a lightweight bottle such as a PET bottle, the container P may be crushed.
For this reason, there is a risk that the container supply amount (processing amount) to the main conveyor 5 is limited and the production efficiency cannot be increased.
Furthermore, the supply state of the containers P to the main conveyor 5 may be shifted to the guide 5G1 side, and the entire transport width of the main conveyor 5 may not be effectively used. Or it may be easily deformed and the life may be shortened.

  Also, when the containers P are discharged from the main conveyor 5 to the discharge conveyor 8 via the connection plate 19, the containers P that are transported away from each other as shown by a broken line B1 in the figure are densely packed toward the guide 19G1. There is a risk that the container P will be damaged due to the large pressure generated by the densely packed containers P in the same manner as the A1 portion on the inlet side of the main conveyor 5 as it is conveyed.

Next, another embodiment of the conventional container processing apparatus will be described with reference to FIGS.
