Abstract

A filling amount adjustment device for a liquid-form substance filling machine, the device including first sliding units disposed on a swing arm and connecting links pivotally attached at one ends to connecting pins of first sliding members (of the first sliding units) that slide along the length of the arm. Second sliding units are disposed on both sides of the swing arm, and the other ends of the connecting links are pivotally connected to the connecting pins of second sliding members (of the second sliding units). Connecting rods connected to piston rods are pivotally connected to the connecting pins. When fine adjustment shafts in which male screws are cut are rotated, the second sliding members are moved and positioned; as a result, the first sliding members slide via the connecting links, thus changing the positions of the connecting pins in the direction of length of the arm.

Dependent claims

A filling amount adjustment device for a liquid-form substance filling machine, wherein in said liquid-form substance filling machine a piston rod is caused to advance and retract by an arm that is connected to a drive section and makes a swing movement, a piston is caused to advance and retract inside a filling cylinder by said piston rod, a predetermined amount of a liquid-form substance is supplied into said filling cylinder, and said liquid-form substance is discharged from said filling cylinder and then released out of a filling nozzle, and wherein said filling amount adjustment device is comprised of:

a first sliding member provided on said arm so that said first sliding member swings together with said arm and slides in a direction of length of said arm, said first sliding member being connected to said piston rod via a connecting member,
a second sliding member that slides in a direction perpendicular to a supporting shaft of said arm and stops at appropriate positions, and
a position regulating member which is provided on said second sliding member and is moved by a sliding movement of said second sliding member, said position regulating member being connected to said first sliding member and guiding a swing movement of said first sliding member along a predetermined path, and wherein
a position of said first sliding member with respect to said direction of length of said arm is adjusted by way of sliding said second sliding member and thus moving said position regulating member.
