A rotating plate is provided on the shaft, and a plurality of lower funnels having different sizes of drop openings are arranged in an annular shape,
And each lower funnel is attached to a respective first driving means provided on the rotary plate, and a single upper funnel for receiving the weighed articles to be packaged is vertically movably provided by the second driving means. The arbitrarily selected lower funnel is lowered by the first driving means and inserted into the packaging bag, and the upper funnel is lowered by the second driving means to match the upper funnel of the lower funnel, and then the article to be packaged. Is discharged into the upper funnel, and the lower funnel is raised by the first driving means to escape from the packaging bag.

According to a second aspect of the present invention, in the filling apparatus for a packaging machine according to the first aspect, the rotary plate is driven and rotated by a driving device having a motor device or an index mechanism to place an arbitrary lower funnel at a filling position. And the lower funnel is exchangeably provided.

According to a third aspect of the present invention, in the filling device for a packaging machine according to the first aspect, the rotating plate is manually rotated to move an arbitrary lower funnel to a filling position, and the lower funnel is exchangeable. Is provided.

[0008]

According to the present invention, the lower funnel corresponding to the width size of the packaging bag is selected from a plurality of lower funnels, and the rotating plate is rotated by any of a motor device, a driving device equipped with an index mechanism, or manual operation. To move any lower funnel to the filling position. The selected lower funnel is lowered by the first driving means, and when the drop opening is inserted into the packaging bag, almost simultaneously with this, the single upper funnel is opened by the second driving means at the upper opening of the lower funnel. , And the weighed items are discharged into the lower funnel. After the discharge, the lower funnel is moved upward by the first driving means to a level at which the lower funnel escapes from the packaging bag. Immediately after the upper funnel discharges the articles to be packaged into the lower funnel, the upper funnel ascends to the original position by the second driving means and waits for the next filling command. Such a series of filling operations are continuously performed so as to correspond to the sequentially supplied packaging bags on the packaging machine side.

[0009] This filling device has a unique structure in which an arbitrary funnel is selected from a plurality of lower funnels having different sizes of a dropping opening according to the size of the opening of the packaging bag. Can be performed quickly and easily. In addition, there is an advantage that the movement and replacement of the lower funnel can be easily performed automatically or manually by a motor device or the like.
