  2. Description of the Related Art A rotary packaging machine having a rotary table having an annular groove for splitting is known as a packaging machine that divides and wraps powder particles such as powders by a required amount. In this packing machine, the powder particles supplied from the receiving hopper are distributed almost uniformly by the vibratory feeder into the annular groove of the rotary table rotated at a constant speed, and then in a direction intersecting the annular groove. The granular material in the annular groove is cut out by the rotating scraping blade according to the number of divisions, and the amount of the cut out granular material is packaged in the packaging portion disposed below. .

  In such a packaging machine, when the type of granular material to be handled is changed, if the previously handled granular material remains in the vibration feeder, the residual granular material is mixed into the next granular material to be handled. There is a problem that is packaged. In particular, when the granular material to be handled is powder, it is not preferable that powders of different components are mixed even if the amount is small. For this reason, when changing the type of the granular material to be handled, the vibration feeder is cleaned to remove the residual content of the previously handled granular material, and then the next granular material is packaged.

  Conventionally, when cleaning the vibration feeder, the vibration feeder has been cleaned manually by an operator. That is, an operator uses cloth or nonwoven fabric to wipe off and remove powder particles remaining in the vibration feeder.

  As described above, the vibration feeder has been conventionally cleaned by the worker's manual work, and the manual work of the worker requires a lot of labor and time, which increases the burden on the worker. .

  Further, in the embodiment of the present invention, when the storage hopper 1 is disposed at the retracted position, the granular material in the storage hopper 1 is sucked, so that it is stored in order to clean the vibration feeder 2. The accommodation hopper 1 can be efficiently cleaned while the hopper 1 is disposed at the retracted position.

  The cleaning device for the vibration feeder in the packaging machine according to the embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the said embodiment, although the accommodation hopper 1 and the vibration feeder 2 are cleaned simultaneously, the structure which cleans only the vibration feeder 2 with the cleaning apparatus 7 may be sufficient. Moreover, in the said embodiment, although the rotary brush 10 of the cleaning apparatus 7 is formed in the substantially same magnitude | size as the internal dimension of the width direction of the conveyance trough 5 of the vibration feeder 2, it does not necessarily need to comprise in the same magnitude | size. good. In this case, if the cleaning device 7 is sequentially transferred in the width direction of the transport trough 5 every time the cleaning device 7 is transferred from the upstream position or the downstream position in the transport direction of the transport trough 5 to the downstream position or the upstream position, the rotating brush 10 can sweep the entire transport space of the transport trough 5.
