A second roller 724c is fixed to a lower end of the support 724d. Further, a second guide member 725 is provided below the support 724d and concentrically with the rotation shaft 721b. The upper end surface 725a of the second guide member 725 plays a role as a rolling surface on which the second roller 724c rolls. The upper end surface 725a is configured to have a different height depending on the circumferential position. As a result, the second roller 724c moves up and down with the rotation of the rotating shaft 721b, so that the support base 724d also moves up and down in the second support portion 724b.

  Here, the first support portion 722b is located directly above the button 100 conveyed along the arc-shaped rail portion 713 by the star wheel 726, and the second support portion 724b is located immediately below the button 100. , The first support portion 722b and the second support portion 724b are arranged.

<< Positioning member >>
The positioning member 800 includes a pair of positioning portions 810 for positioning both side surfaces of the button 100 and a pressing portion 820 for pressing the upper end of the button 100 (near the pressed portion 120). The surface of the pressing portion 820 has a spherical shape so as to allow the button 100 to swing back and forth even when both sides of the button 100 are positioned by the positioning portion 810. However, the surface shape of the pressing portion 820 is not limited to a spherical shape as long as swinging of the button 100 is permissible, and other shapes may be employed.

<< Operation of mounting device >>
In particular, the operation of the mounting device will be described with reference to FIG. FIG. 11 illustrates the first roller 722c and the second roller 724c when the first guide member 723 and the second guide member 725 are viewed in the centrifugal direction from the rotation center axis side of the rotation shaft 721b with respect to the container conveyance device 720. The behavior of is shown. Therefore, in FIG. 11, the direction from the left side to the right side is the direction from the upstream side to the downstream side in the transport direction of the button 100. 11, the positional relationship between the first rolling surface 723a and the second rolling surface 723b of the first guide member 723 and the first roller 722c, the upper end surface 725a of the second guide member 725 and the second The positional relationship with the roller 724c is shown by a solid line. The arc-shaped rail 713, the button 100, the positioning member 800, the container C and the like are indicated by dotted lines according to the respective positions of the first roller 722c and the second roller 724c.

  When the button 100 is transported along the first arc-shaped rail portion 713a, the positioning member 800 located directly above the button 100 gradually descends as it approaches the second arc-shaped rail portion 713b. Before the button 100 reaches the second arc-shaped rail portion 713b, the first roller 722c passes over the tip of the first rolling surface 723a of the first guide member 723, so that the positioning member 800 is moved to the first support portion. It falls within 722b. As a result, the button 100 is positioned by the positioning member 800.

Thereafter, the button 100 moves to the second arc-shaped rail portion 713b while maintaining the position determined by the positioning member 800. Although the second arc-shaped rail portion 713b only supports the lower end of the button 100 and has no function of positioning the button 100 in the rotation direction, the button 100 is positioned in the rotation direction by the positioning member 800. Further, while the button 100 is being conveyed on the second arc-shaped rail portion 713b, the container C located immediately below the button 100 gradually rises. As a result, the button 100 and the tip 621 of the stem 620 provided on the container C are brought close to each other.

  Then, when the button 100 crosses the tip 713c of the arc-shaped rail portion 713, the button 100 drops together with the positioning member 800. A range P1 in FIG. 11 indicates a step of dropping the button 100 (first step). By this dropping step, the button 100 is put on the mounting cup 630. Thereafter, the first roller 722c rolls on the second rolling surface 723b of the first guide member 723. As a result, the positioning member 800 gradually moves downward, whereby the button 100 is pressed downward, and the attachment of the button 100 to the valve 600 ends. A range P2 in FIG. 11 indicates a pressing step (second step) of the button 100.

  Hereinafter, the behavior of the button 100 in the dropping step (first step) and the pressing step (second step) will be described with reference to FIGS. 12 to 14. As can be understood from the above description, the mechanism (positioning mechanism) for performing the dropping process includes various members (in particular, the arc-shaped rail portion 713, the star wheel 726, and the like) that constitute the button transport device 710 and the container transport device 720. (A positioning member 800). In addition, a mechanism (pressing mechanism) for performing the pressing step is formed by various members (particularly, the first roller 722c, the second rolling surface 723b of the first guide member 723, and the positioning member 800) constituting the container conveying device 720. Be composed. Hereinafter, for convenience of description, the central axis of the stem 620 is referred to as “second central axis L2”.

<< Falling process (first process) >>
In the dropping step, first, the button 100 is positioned at a position where the first central axis L1 is shifted toward the pressed portion 120 with respect to the second central axis L2. More specifically, the button 100 is positioned such that the first reference plane F1 is located on the second central axis L2, and the second reference plane F2 is shifted toward the pressed portion 120 with respect to the second central axis L2. You. In a state where the button 100 is positioned, the distance S between the second center axis L2 and the first center axis L1 is such that the engagement projection 111 does not collide with the peripheral edge 634 of the mounting cup 630 while the button 100 is falling. It is set as follows.

  With the button 100 positioned as described above, as described above, when the button 100 passes over the tip 713c of the arc-shaped rail portion 713, the button 100 drops together with the positioning member 800 (see arrow X in FIG. 12). ). In FIG. 12, the space between the mounting cup 630 and the button 100 is drawn wider for the sake of convenience of description, but in actuality, the distance is about several mm.

  When the button 100 is dropped, first, the protrusion 112 abuts on the peripheral edge 634 of the mounting cup 630. FIG. 13 shows a state immediately after the protrusion 112 collides with the peripheral edge 634. When the protruding portion 112 abuts on the peripheral portion 634, the center of gravity of the button 100 is near the insertion hole portion 130. It tilts so as to move to the 631 side (see the arrow R1 in FIG. 13). In the process of tilting the button 100, the tip of the stem 620 abuts against the inclined surface 133 of the insertion hole 130. The inclined surface 133 guides the inclination direction of the button 100 such that the tip of the stem 620 faces the step surface 132 and the engagement protrusion 111 enters below the peripheral portion 634.

<< Pressing step (second step) >>
After the button 100 is guided in the inclination direction by the inclined surface 133, the engagement projection 111 is positioned below the peripheral edge 634, and the projection 112 is placed on the peripheral edge 634. (See FIG. 14). FIG. 14 shows the state of the button 100 and the like between the range P1 of the dropping process and the range P2 of the pressing process in FIG.

  As described above, since the first roller 722c rolls on the surface of the second rolling surface 723b of the first guide member 723, the positioning member 800 gradually moves downward. Is pressed downward. As a result, the button 100 is tilted so that the protruding portion 112 enters the inside of the peripheral portion 634 (see the arrow R2 in FIG. 14), and is then further pushed downward. As a result, the button 100 is pushed into a position where the step surface 132 of the insertion hole portion 130 comes into contact with the foremost surface 622 of the stem 620, and the body portion 110 is inserted inside the peripheral portion 634 of the mounting cup 630. (The state shown in FIG. 1). Through the above steps, the button 100 is attached to the valve 600.
