A link apparatus comprising: plural hopper groups each including n ( n: plural number) hoppers for holding objects to be packaged which are supplied to the hoppers and discharging the objects; and plural conveyor means (31, 32) each comprising an arm, which are provided to respectively correspond to the hopper groups and configured in such a manner that each hopper group is attached to a first end portion of a respective arm and the arms are each rotatable around second end portions thereof which are on an opposite side from the first end portions respectively, wherein the plural conveyor means (31, 32) include a first conveyor means and a second conveyor means; the second end portion of the arm of the first conveyor means is coupled to a rotary shaft which is provided at a location around which the arms of the conveyor means are rotatable; the second end portion of the arm of the second conveyor means is coupled to a rotary tubular body into which the rotary shaft is inserted; wherein the arms are configured to be independently driven; the arms are respectively configured to convey the hopper groups such that the hoppers belonging to each hopper group are arranged in one line in a direction along a revolving path including a first area (Fs) where, in use, the objects are to be supplied to the n hoppers belonging to the hopper group and a second area (Fd) under which, in use, package bags are to be arranged in one line in the direction along the revolving path and are to be conveyed successively, the first area being a part of the revolving path and the second area being another part of the revolving path; wherein the conveyor means (31, 32) are respectively configured to convey the hopper groups such that the hopper groups are repeatedly conveyed from the first area to the second area in a predetermined order; the conveyor means (31, 32) are respectively configured to convey associated hopper groups such that the n hoppers in each of the hopper groups sequentially conveyed to the second area are, in use, to be respectively located above n package bags which are to be sequentially conveyed to a region under the second area; and the conveyor means (31, 32) are respectively configured to convey the hopper groups such that the n hoppers in each of the hopper groups are, in use, to be respectively located above the n package bags in the second area; the conveyor means (31, 32) are respectively configured to stop the hopper groups in the first area or convey the hopper groups in the first area at a speed lower than a speed in the second area; and wherein the hopper groups are each configured to discharge the objects from the n hoppers to n package bags which, in use, are to be respectively located below the n hoppers, when the hopper groups are conveyed in the second area. plural hopper groups each including n ( n: plural number) hoppers for holding objects to be packaged which are supplied to the hoppers and discharging the objects; and plural conveyor means (31, 32) each comprising an arm, which are provided to respectively correspond to the hopper groups and configured in such a manner that each hopper group is attached to a first end portion of a respective arm and the arms are each rotatable around second end portions thereof which are on an opposite side from the first end portions respectively, wherein the plural conveyor means (31, 32) include a first conveyor means and a second conveyor means;
