Yes. That is, the part alignment passage 59 is disposed on one side with respect to the extension line 90, and one gas discharge passage 47 is disposed on the other side with respect to the extension line 90.

  The gas injection unit 14 illustrated in FIG. 1 is an example of a “fluid injection unit”. The gas injection unit 14 injects gas which is an example of “fluid”. The injection port of the gas injection unit 14 is connected to the gas supply port 73 and the component supply port 21 described above via a pipe (not shown).

  Next, the operation of the above-described component supply apparatus 10 will be described.

  When the gas 110 is injected from the gas injection unit 14, the gas 110 is injected from the component supply port 21 and the gas supply port 73 into the component transport passage 74 through the component supply passage 75 and the gas supply passage 46. A plurality of micro screws 100 are introduced into the component supply passage 75 from the component supply port 21. The plurality of micro screws 100 introduced into the component supply passage 75 are supplied into the component conveyance passage 74 by the gas 110 injected from the gas injection unit 14. In the component conveyance path 74, the plurality of micro screws 100 are conveyed by the gas 110 injected from the gas injection unit 14. At this time, the conveying direction of the plurality of micro screws 100 is the direction indicated by the arrow R direction.

  As described above, the component conveyance passage 74 has a height and a width that are larger than the larger one of the axial length of the micro screw 100 and the diameter of the head 101. Accordingly, as shown in FIG. 8, the plurality of micro screws 100 are transported in the component transport path 74 regardless of the posture (conveyed while changing the posture).

  Then, when the micro screw 100 transported through the component transport passage 74 reaches the connection port 89 of the component alignment passage 59 with the component transport passage 74, the micro screw 100 is in either a correct posture or an incorrect posture. The normal posture of the micro screw 100 in this case is a posture in which the head 101 is erected as shown in FIG. In a state where the micro screw 100 is in the normal posture and is lowered by its own weight and is positioned at the center in the width direction of the component transport passage 74, the micro screw 100 in the normal posture flows into the component alignment passage 59 and is aligned ( (See also FIG. 10). The first micro screw 100 among the plurality of micro screws 100 aligned in the component aligning passage 59 is taken out from the component outlet 72 shown in FIG.

There may be. The micro screw 100 in the wrong posture cannot flow into the component alignment passage 59 and goes around the component conveyance passage 74 until it flows into the component alignment passage 59.

  Next, the operation and effect of this embodiment will be described.

  As described above in detail, according to the component supply apparatus 10 of the present embodiment, the component conveying member 12 includes a laminate formed by laminating a plurality of members that form the component conveying passage 74 and the component alignment passage 59. Has been. Therefore, even when the cross-sectional areas of the component conveying passage 74 and the component aligning passage 59 are made minute corresponding to the minute screw 100, the component conveying passage 74 and the component aligning passage 59 are formed by dividing them into a plurality of members. The component conveyance passage 74 and the component alignment passage 59 can be easily formed. Thereby, even when the conveyance target is a plurality of micro screws 100, the plurality of micro screws 100 can be aligned in a normal posture.

  In addition, since the component conveying member 12 is a laminated body formed by laminating a plurality of members, the structure is simplified. In the component supply apparatus 10, the gas injection unit 14 is used to convey the micro screw 100. Therefore, for example, the entire structure of the component supply apparatus 10 can be simplified as compared with a picking method using a robot, a stirring method using a hopper, and the like.

  Thus, according to the component supply apparatus 10 of the present embodiment, it is possible to align the plurality of micro screws 100 in a normal posture while simplifying the structure.

  Moreover, according to the component supply apparatus 10 of this embodiment, since a structure can be simplified, the cost reduction of the component supply apparatus 10 can be achieved.

  Even when the cross section of the component conveying passage 74 and the component aligning passage 59 is made minute corresponding to the minute screw 100, the component conveying passage 74 and the component aligning passage 59 are formed by dividing them into a plurality of members. The conveyance path 74 and the part alignment path 59 can be formed in appropriate shapes. Thereby, retention, clogging, etc. of the micro screw 100 can be suppressed.

  Further, as shown in FIG. 4, in the conveyance direction of the plurality of micro screws 100 in the component conveyance passage 74, there is one between the connection port 86 of the gas supply passage 46 and the connection port 85 of the component supply passage 75. A connection port 87 of the gas discharge passage 47 is arranged. Accordingly, a part of the gas injected from the gas supply passage 46 can be discharged to the outside through the one gas discharge passage 47. Thereby, it is possible to suppress the occurrence of turbulent flow due to interference between the gas injected from the connection port 85 of the component supply passage 75 and the gas injected from the connection port 86 of the gas supply passage 46.

  Similarly, the other gas discharge passage 48 is connected between the connection port 85 of the component supply passage 75 and the connection port 86 of the gas supply passage 46 in the conveyance direction of the plurality of micro screws 100 in the component conveyance passage 74. A mouth 88 is disposed. Therefore, part of the gas injected from the component supply passage 75 can be discharged to the outside through the other gas discharge passage 48. Thereby, it is possible to suppress the occurrence of turbulent flow due to interference between the gas injected from the connection port 85 of the component supply passage 75 and the gas injected from the connection port 86 of the gas supply passage 46.

  As described above, since turbulent flow due to gas interference can be suppressed, a plurality of micro screws 100 can be smoothly transferred in the component transfer passage 74, and retention or clogging of the micro screws 100 can be suppressed. Can do.

  Further, as shown in FIG. 8, the connection port 86 of the gas supply passage 46 is formed in the second plate member 40 and is located higher than the component alignment passage 59 formed in the third plate member 50. Therefore, by ejecting the gas 110 from the connection port 86 of the gas supply passage 46, the micro screw 100 in the component conveyance passage 74 can be positively lowered. Thereby, the micro screw 100 can smoothly flow into the component alignment passage 59 in which the top surface 59A is lower than the top surface 74A of the component transport passage 74.

  Further, as shown in FIG. 4, in a plan sectional view of the component conveying member 12, the component alignment passage 59 and one gas discharge passage 47 are arranged on both sides of the extension line 90 of the central axis of the gas supply passage 46. Yes. Therefore, the gas injected from the connection port 86 of the gas supply passage 46 can be distributed to the component alignment passage 59 side and the one gas discharge passage 47 side. Thereby, when the micro screw 100 is in the normal posture, the micro screw 100 in the normal posture can be caused to flow into the component alignment passage 59. If the micro screw 100 is in the wrong posture, the micro screw 100 in the wrong posture can be caused to flow toward the one gas discharge passage 47, and the micro screw 100 in the wrong posture can be smoothly moved in the component conveying passage 74. Can be circulated.
