Packer scale having a hopper body suspended by suspending units

A packer scale for charging objects with a predetermined weight into each bag, the packer scale comprising:

• a weighing hopper which is supplied with the objects dropped from above, holds the objects for a specified period and discharges the objects downward;
• first to fourth load cells having shaft-like load application sections, respectively;
• and
• first to fourth suspending units which suspend the weighing hopper such that the weighing hopper is mounted to the load application sections of the first to fourth load cells;
• wherein the weighing hopper includes a hopper body having a tubular shape with a rectangular cross-section, in a plan view;
• and
• wherein the first to fourth suspending units are mounted to an upper portion of the hopper body, in locations which are in the vicinity of corner portions of the tubular shape;
• wherein each of the suspending units includes:
• a first member mounted to the load application section of the load cell;
• and
• a second member fastened to the weighing hopper;
• wherein the first member has a first hole extending in a predetermined first axis direction and a second hole extending in a second axis direction which three-dimensionally crosses the first axis;
• wherein the first member is mounted to the load application section of the load cell via a first ball bearing fitted to the first hole such that the first member is rotatable relative to the load application section;
• and
• wherein the second member is mounted to the first member via a second ball bearing fitted to the second hole of the first member such that the second member is rotatable relative to the first member.
