The work 31 is dispersed and placed on the work placement unit 30 in an indefinite posture, and a part of the work 31 falls downward from the opening 67 and returns to the storage unit 62 via the inclined surface 61. In the work supply process, the work supply device 40 moves the sampling unit 42 along a predetermined trajectory without considering the posture and how much of the work 31 stored in the storage unit 62 is stored.

In the work transfer process, the work transfer device 20 first carries in and carries the work placing unit 30 by the carrying unit 14, and fixes the work placing unit 30 at the transfer position. Next, the work transfer device 20 causes the imaging unit 25 to capture an image of the collection mounting unit 63 (FIG. 8A), recognizes the mountable workpieces 31 and mounts the workpieces. The predetermined position 32 of 31 is recognized. The recognition processing of the work 31 is prepared in advance by, for example, binarization processing, pattern matching processing, or the like to distinguish the area of the sampling placement unit 63 in the captured image from the other area (area of the work 31). This can be done by identifying a work area that matches the reference shape data of the created work 31. In the recognition processing of the work 31, for example, as shown in FIG. 9, of the areas of the work 31 of the captured image 80, the area that matches the reference shape data of the work 31 is recognized as the extractable work area 81, and the work 31 is recognized. An area that does not match the reference shape data may be recognized as the uncollectable work area 82. The reference shape data may include, for example, the shape when the work 31 is viewed from a plurality of angles. From the viewpoint of more reliably collecting the work 31, the work 31 that can be collected may be, for example, one that does not overlap in a complicated manner, or one that is not mounted on the edge of the mounting portion 63 for collection. .. In the recognition process of the predetermined position 32, after recognizing the collectable work 31, the tip portion of the collectable work 31 is recognized (see FIG. 9 ).
