  • the timing of charging the powder P stored inside the stocker 3 into the stocker 3 may be any time before the powder P is supplied, but from the viewpoint of operability, after the powder P is charged into the stocker 3, the stocker 3 is charged. It is preferable to attach 3 to the main body 2.
  • the control unit 211 of the main body 2 Operate the control unit 211 of the main body 2 to supply the powder P from the stocker 3 mounted on the main body 2.
  • the exhaust unit 42 is driven, flows into the inside of the casing 41 from the gap 7, passes through the first region A, the filtration member 43, the second region B, and the exhaust unit 42 in this order, and the casing 41 A flow F of air exhausted to the outside (see FIGS. 3 and 4) is generated. Since the dust generated by the supply of the powder P from the stocker 3 moves toward the filtration member 43 by the air flowing inside the casing 41, the dust can be collected by the filtration member 43.
  • the exhaust unit 42 takes a predetermined time after the supply of the powder P from the stocker 3 to the container 5 is stopped. Stop after the lapse of time. Therefore, the exhaust unit 42 is driven while the powder P is being supplied. This makes it possible to prevent dust from being generated after the exhaust unit 42 is stopped.
  • the supply of the powder P from the stocker 3 may be started and stopped by repeating an arbitrary number of times depending on the situation of the supply work. At that time, the exhaust unit 42 is driven at the start of the first supply of the powder P from the stocker 3, and is stopped after a predetermined time has elapsed after all of the repeated supply of the powder P is completed. This makes it possible to prevent dust from being generated after the exhaust unit 42 is stopped.
  • each stocker 3 supplies the powder P one by one in order.
  • the exhaust unit 42 is driven at the start of supply from the first stocker 3 for supplying the powder P, and for a predetermined time after the supply from the last stocker 3 for supplying the powder P is completed. Stop after the lapse of time. Also in this case, it is possible to prevent dust from being generated after the exhaust unit 42 is stopped.
  • the powder supply process is completed, the container 5 is carried out, and a new container 5 is installed. The following powder supply process is performed.
  • the stocker 3 is separated from the main body 2.
  • the supply device 1 can collect dust generated when the powder P is supplied from the side by the supply unit 32, can prevent deterioration of the working environment, and saves space. , It is a simple structure. Further, it is possible to prevent the powder P that has fallen from the filtration member 43 from flowing out to the outside of the dust collecting unit 4, and it is possible to efficiently control the supply unit 32 and the exhaust unit 42, so that the powder P can be controlled. The weight can be measured accurately. It is also possible to adjust the flow velocity of the air flowing into the dust collecting portion 4 according to the particle size of the powder P to be supplied.
  • the present invention is not limited to the above-described embodiment, and modifications and the like can be added within a range that does not deviate from the technical idea of the present invention. It will be included in the technical scope.
  • the number of stockers 3 attached to the main body 2 is four in the above embodiment, but an appropriate number such as 1, 2, 3, 5, ... Can be adopted.
  • the dust collecting unit 4 is used to measure the weight of the powder P supplied to the container 5, but it can also be applied to powder processing equipment for other purposes.
