  • the inclined portion 331 also has a function of promoting forward movement of the plurality of components 92 discharged from the component case 32 , thereby preventing the plurality of components 92 from staying near the discharge port 321 .
  • the inclined portion 331 can adopt various modes according to the position and shape of the discharge port 321 of the component case 32 attached to the receiving member 33 .
  • the inclined portion 331 may be formed in a curved surface instead of a flat surface.
  • the length of the inclined portion 331 in the front-rear direction and the angle of inclination with respect to the horizontal plane are appropriately set.
  • the length and angle of the inclined portion 331 depend on the positional relationship between the discharge port 321 and the air discharge port of the air supply device 39, the dimensions and shape of the component 92, and the operating characteristics of the vibration excitation device for component discharge. set based on
  • the plurality of parts 92 are preferably moved from the lower portion of the discharge port 321 to the air discharge port. Therefore, it is possible to suitably perform the ejection operation of the plurality of parts 92, the movement to the air discharge port, and the circulation operation by blowing up using the positive pressure air. From the viewpoint of the functions required of the receiving member 33 and the manufacturing cost, the mode illustrated in the embodiment is preferable.
  • the track member 35 of the bulk feeder 30 is configured to include an alignment member 353 in which a plurality of cavities 354 are formed.
  • the alignment member 353 may be omitted. That is, in the supply area As of the track member 35, a concave portion where the components 92 are dispersed at a position lower than the upper surface of the transport path R and a planar portion that is uniform with the upper surface of the transport path R are formed so that the parts can be stored in a bulk state. 92 may be provided.
  • the configuration exemplified in the embodiment is preferable from the viewpoint of improving the efficiency of the component supply process and reducing the image processing load in the process of recognizing the supply state in the supply area As.
