Abstract

PROBLEM TO BE SOLVED: To increase preform feed capacity by taking out, by a plurality of prescribed rows in the lateral direction, preforms maintained in a falling condition at a supporting pin planted perpendicularly in a tray, adjusting the pitch and row-to-row interval of the supporting pin for aggregation into a single row, drawing it out of the supporting pin, and reversing and erecting it for discharge. SOLUTION: When a preform 10 is taken out and transferred, the lateral pitches of supporting pins in both interval traveling mechanisms on the stationary side and the traveling side are the same as the lateral pitch of the preform 10 and are on the identical line. When a traveling member 71 where the preform 10 is placed increases an interval, feed direction line positions are positioned in a zigzag form each other. When they approach each other under this condition, the preforms 10 are aligned in a single row. When a reversing device 75 takes the preform 10 out of an aggregate device 61, a supporting base lifts and gets out of the supporting pin. A rotating table 78 rotates by 180 degrees to be erected, thus engaging and delivering the preform 10 to a delivery device.

It is a commercially available blow molding machine that performs the steps of container molding by clean air blowing, holding and cooling, mold opening, and container removal. In FIG. 10B, the preform 10
A blow-molded product container 11 is shown in perspective view.

The container 11 is carried into the filling chamber 101 by the container conveyor 18, where the rotary filling machine 6 is adjusted while the delivery timing is adjusted by a star wheel or the like.
Then, the rotary filling machine 6 fills the container 11 with the liquid while rotating in the arrow direction of FIG. The container 11 filled with the liquid is moved to the capping machine 7 in the next step by the container conveyor 19, where it is capped, sealed, and sent to the packaging step by the discharge conveyor 20.

In the above manufacturing facility, when the liquid to be filled in the container 11 is a beverage, it is necessary to provide a device for cleaning the preform or the container in the middle of the single-row preform conveyor 17 or the container conveyor 18. There is. When the filling liquid requires cold filling of beverages such as carbon dioxide gas, a sterilizing device is required in the previous conveyor.
