It is the perspective view which showed one Embodiment of the parts alignment supply apparatus which concerns on this invention. It is a top view of the parts alignment supply apparatus shown in FIG. It is a side view of the parts alignment supply apparatus shown in FIG. It is sectional drawing which showed notionally the principal part of the parts alignment supply apparatus shown in FIG.

  Hereinafter, a parts alignment and supply apparatus according to the present invention will be described in detail with reference to the drawings.

  The illustrated parts alignment and supply apparatus 1 includes a cylindrical container 10 that houses a large number of parts A, for example, O-rings, a disk 20 that forms the bottom surface of the cylindrical container 10, and a linear shape that is connected to the cylindrical container 10. A passage 30, a belt conveyor 40 that forms the bottom surface of the linear passage 30, and an air blow 50 that ejects air into the passage toward the distal end are provided at the base end of the linear passage 30.

  The cylindrical container 10 has an outlet 11 that is open at the top and allows a single part A to pass through the lower peripheral wall, that is, the width and height are slightly larger than the width and thickness of the part A. Further, an annular unevenness 12 is formed on the inner wall surface of the cylindrical container 10 along the peripheral surface, and the inner surface is coated with a fluororesin. The cylindrical container 10 includes a lid 13. The lid 13 is arranged to be opened and closed by a hinge 14.

  As shown in FIG. 4, the disk 20 is formed by an inclined surface 21 inclined downward from the center toward the periphery, and an annular flat surface 22 having a step at the periphery and having a width for accommodating the part A. Has been. The disk 20 is formed of an antistatic material. The disk 20 is rotated by a motor 23 to bring the part A to the inner peripheral wall of the cylindrical container 10 by centrifugal force. Further, in this disk 20, the parts A on the disk slide in the peripheral direction due to the inclination of the inclined surface 21, and are dropped onto the annular flat surface 22 and are aligned there.

  The straight passage 30 is open at the top. As shown in FIG. 2, the linear passage 30 includes a guide member 31 on the upper surface thereof. The guide member 31 is formed of a plate having substantially the same length as that of the linear passage 30 and is disposed so as to be freely retractable with respect to the upper opening. And the guide member 31 is located on the opening of the linear channel | path 30, and guides the parts A conveyed there. Further, when the part A is clogged in the linear passage 30 or the linear passage 30 is cleaned, the guide member 31 is retracted from the opening of the linear passage 30 to open the linear passage 30, and the part A is removed. Remove or make cleaning easier.

  The belt conveyor 40 is formed of rubber, and is wound around a driving pulley 41 disposed at the distal end of the linear passage 30 and a driven pulley 42 disposed at the proximal end, as shown in FIG. The lower part of the belt conveyor 40 is also passed over the tension pulley 43, so that the belt conveyor 40 is always tensioned.
