The same can be said about the said content about the object Tg0 conveyed to the other empty space 34d among a pair of empty space 34d, 34d.

In this way, when the vibrating device 40 conveys a plurality of supplies 90 s in a direction along the extending direction (arrow SD direction) of the trough-shaped conveyance path Rd0 , it is difficult to transfer the supplies along the trough-shaped conveyance path Rd0 . The supply 90 s between the pair of side wall surfaces 34a, 34a extending in the extending direction (arrow SD direction) and the collection part Pu0 is conveyed to the collection part Pu0. Therefore, the bulk feeder 30 of this embodiment is provided with the guide member 80 .

The guide member 80 guides the object Tg0 to the side of the collection unit Pu0 when the object Tg0 is further conveyed in a direction along the extending direction (arrow SD direction). The guide member 80 may take various forms as long as it can guide the object Tg0 to the side of the collection unit Pu0 when the object Tg0 is conveyed. As shown in FIG. 7, the guide member 80 of the present embodiment includes a pair of corner inclined surfaces 81, 81 formed by chamfering a pair of corners 34c, 34c respectively. The pair of corners 34c, 34c are formed by The front end side wall surface 34b provided on the front end side in the extending direction (arrow SD direction) of the groove-shaped conveyance path Rd0 is formed with a pair of side wall surfaces 34a, 34a.

The pair of corner inclined surfaces 81 and 81 guide the target object Tg0 arrived by the forward conveyance to the predetermined area Ap0 on the side of the collection unit Pu0. The predetermined area Ap0 is an area where the object Tg0 guided by the pair of corner inclined surfaces 81 and 81 can be transported to the pick-up unit Pu0 by backward transport. As shown in FIG. 7 , the predetermined area Ap0 is provided in the collection part Pu0 with respect to a pair of corner inclined surfaces 81 and 81 in the width direction (arrow WD direction) of the conveyance path Rd0 perpendicular to the extending direction (arrow SD direction). side.

For example, the vibrating device 40 forward-conveys the object Tg0 conveyed to one of the empty spaces 34d among the pair of empty spaces 34d and 34d. Thereby, the object Tg0 is conveyed to an area on the front end side in the extension direction (arrow SD direction) of the one free space 34d, and reaches one of the pair of corner inclined surfaces 81, 81 (refer to arrow L21). When the vibration excitation device 40 further advances and conveys the object Tg0 that has reached the one corner inclined surface 81 , the object T90 is conveyed along the one corner inclined surface 81 to a predetermined area Ap0 (see arrow L22 ). When the vibration excitation device 40 reverses and conveys the object Tg0 conveyed to the predetermined area Ap0 , the object Tg0 is conveyed to the collection unit Pu0 (see arrow L23 ). The same applies to the object Tg0 conveyed to the other empty space 34d of the pair of empty spaces 34d, 34d and the other corner inclined surface 81 among the pair of corner inclined surfaces 81,81.

The pair of corner inclined surfaces 81 and 81 may take various forms as long as they can guide the target object Tg0 reached by forward conveyance to the predetermined area Ap0. The pair of corner inclined surfaces 81, 81 may be convex curved surfaces protruding toward the sides of the pair of corners 34c, 34c, or may be flat surfaces as shown in FIG. 7 . In addition, the inclination angle of the pair of corner inclined surfaces 81, 81 with respect to the pair of side wall surfaces 34a, 34a and the inclination angle with respect to the front end side wall surface 34b can be set arbitrarily. Furthermore, the angle of inclination of the pair of angled inclined surfaces 81, 81 relative to the pair of side wall surfaces 34a, 34a and the angle of inclination of the pair of angled inclined surfaces 81, 81 relative to the top side wall surface 34b can be different, as shown in FIG. 7 As shown generally the same (tilt angle is 45 degrees).

In addition, the inclination angles of the pair of corner inclined surfaces 81, 81 can also be determined by the positions of the first connection portion 81a connected to the side wall surface 34a and the second connection portion 81b connected to the top end side wall surface 34b. For example, as shown in FIG. 7, a pair of corner inclined surfaces 81, 81 may be provided in an area closer to the tip side than the first range Rg1 where the collection unit Pu0 is provided in the extending direction (arrow SD direction) of the conveyance path Rd0. The first connection portion 81a connected to the side wall surface 34a. Thereby, compared with the case where the first connecting portion 81a is provided in the first range Rg1, it is easier to ensure the distance between the pair of side wall surfaces 34a, 34a and the collection portion Pu0 in the pair of empty spaces 34d, 34d.

In addition, as shown in FIG. 7 , a pair of corner inclined surfaces 81, 81 can be placed on the first side of the collection unit Pu0 in the width direction (arrow WD direction) of the conveyance path Rd0 perpendicular to the extending direction (arrow SD direction). In the second range Rg2, a second connection portion 81b connected to the top side wall surface 34b is provided. Thereby, compared with the case where the 2nd connection part 81b is provided in the area|region other than the 2nd range Rg2, it becomes easier to guide the object Tg0 which arrived by forward conveyance to the predetermined area|region Ap0.

Furthermore, a pair of empty spaces 34d, 34d are provided according to various situations. For example, the pair of empty spaces 34d and 34d are provided in such a manner that, for 90 s, the supplies transported to the collecting unit Pu0 are collected from the holding member 13d of the substrate working machine WM0 (the component mounting machine 10 in this embodiment) , the holding member 13d does not interfere with the side wall surface 34a. In addition, the substrate working machine WM0 (parts mounting machine 10 ) photographs a plurality of supplies 90 s in order to identify the supplies 90 s that can be collected by the holding member 13 d from among the plurality of supplies 90 s conveyed to the collection unit Pu0 , and the photographed image processing. The pair of empty spaces 34d and 34d are provided so that the side wall surface 34a captured in the image does not become an obstacle when the state of the plurality of supplies 90s is recognized by image processing.

In this embodiment, regarding the pair of free spaces 34d and 34d, a pair of side wall surfaces is set by collecting a plurality of supplies 90s and recognizing the states of a plurality of supplies 90s with respect to the substrate working machine WM0 (parts mounting machine 10 ). The distance between 34a, 34a and the collection part Pu0 is such that the pair of side wall surfaces 34a, 34a do not become obstacles. The distance between the pair of side wall surfaces 34a, 34a and the collection part Pu0 is set in advance by simulation, verification with an actual machine, or the like. In addition, the case where a pair of empty space 34d, 34d is provided is not limited to the said case. For example, in the form in which the collection unit Pu0 is provided with the detachable cavity unit 50 , a pair of empty spaces 34 d and 34 d may be provided to facilitate the attachment and detachment of the cavity unit 50 .

In addition, in the present embodiment, the collecting unit Pu0 includes a cavity unit 50 including a plurality of cavities 51 that are to accommodate one supply 90s among a plurality of supplies 90s. The guide member 80 can guide the object Tg0 to the side of the collection part Pu0 regardless of the form in which a plurality of supplies 90s are scattered in the collection part Pu0 or the form provided with the cavity unit 50 . Furthermore, the plurality of supplies 90 s are not limited as long as they are supplied to the substrate working machine WM0 (the component mounting machine 10 in this embodiment). In the present embodiment, the plurality of supplies 90 s are components 91 or solder balls 92 supplied to the substrate 90 .

The protruding part 82 restricts the case where a predetermined angle is guided to the side of the one corner inclined surface 81 (for example, the left side of the paper in FIG. 8 ) by one of the pair of corner inclined surfaces 81, 81. The object Tg0 in the area Ap0 moves to the predetermined area Ap0 on the side of the other corner inclined surface 81 (for example, on the right side of the paper in FIG. 8 ). Likewise, the protruding portion 82 restricts the case where it is guided to the side of the other corner inclined surface 81 from among the pair of corner inclined surfaces 81, 81 (the paper surface of FIG. 8 ). The object Tg0 in the predetermined area Ap0 on the right side) moves to the predetermined area Ap0 on the side of the one corner inclined surface 81 (the left side of the drawing in FIG. 8 ).

For example, the vibrating device 40 forwardly conveys the object Tg0 conveyed to one of the pair of empty spaces 34d, 34d (the left side of the sheet of FIG. 8 ). Thereby, the object Tg0 is conveyed to an area on the front end side in the extension direction (arrow SD direction) of the one free space 34d, and reaches one of the pair of corner inclined surfaces 81, 81 (refer to Arrow L31a). When the vibration excitation device 40 further advances and conveys the object Tg0 that has reached the one corner inclined surface 81, the object Tg0 is conveyed along the one corner inclined surface 81 and is guided to the one corner inclined surface 81. The predetermined area Ap0 on the side (the left side of the paper in Fig. 8). At this time, the movement of the object Tg0 to the predetermined area Ap0 on the side of the other corner inclined surface 81 (the right side of the paper in FIG. 8 ) is restricted by the protruding portion 82 (see arrow L32 a ). When the vibrating device 40 performs backward conveyance of the object Tg0 , the object T90 is conveyed to the pick-up unit Pu0 (see arrow L33 a ).

Similarly, the vibration excitation device 40 forwardly conveys the object Tg0 conveyed to the other empty space 34d (the right side of the sheet of FIG. 8 ) among the pair of empty spaces 34d, 34d. Thereby, the object Tg0 is conveyed to an area on the front end side in the extending direction (arrow SD direction) of the other free space 34d, and reaches the other corner inclined surface 81 of the pair of corner inclined surfaces 81, 81. (refer to arrow L31b). When the vibration excitation device 40 further advances and conveys the object Tg0 that has reached the inclined surface 81 at the other corner, the object Tg0 is conveyed along the inclined surface 81 at the other corner and guided to the other corner. The predetermined area Ap0 on the side of the inclined surface 81 (the right side of the sheet of FIG. 8 ). At this time, the movement of the object Tg0 to the predetermined area Ap0 on the side of the one corner inclined surface 81 (left side of the paper in FIG. 8 ) is restricted by the protruding portion 82 (see arrow L32 b ). When the vibrating device 40 performs backward conveyance of the object Tg0 , the object Tg0 is conveyed to the pick-up unit Pu0 (see arrow L33 b ).

Protrusion 82 may take various forms. For example, the protruding part 82 includes a pair of protruding part inclined surfaces 82a, 82a, and restricts the movement of the object Tg0 guided to the predetermined area Ap0. Each of the pair of protrusion inclined surfaces 82a, 82a may be a curved surface, or may be a plane as shown in FIG. 8 . In addition, the inclination angles of the pair of protrusion inclined surfaces 82a and 82a with respect to the plane corresponding to the front end side wall surface 34b can be set arbitrarily. Furthermore, the inclination angles of the pair of protrusion inclined surfaces 82a, 82a with respect to the plane corresponding to the top end side wall surface 34b and the inclination angles of the pair of corner portion inclined surfaces 81, 81 with respect to the plane corresponding to the top end side wall surface 34b may be different. It can also be the same as shown in Figure 8 (for example, the inclination angle is 45 degrees).

2-2. Second deformation form The guide member 80 may include a pair of side wall surface inclined portions 83 , 83 . As shown in FIG. 9 , the pair of side wall surface inclined portions 83, 83 are formed so that they are closer to the front end side than the first range Rg1 where the collection portion Pu0 is provided with respect to the extending direction (arrow SD direction) of the conveyance path Rd0. The distance between the pair of side wall surfaces 34a, 34a in the area of ? becomes shorter toward the tip side.

For example, the vibrating device 40 forward-conveys the object Tg0 conveyed to one of the empty spaces 34d among the pair of empty spaces 34d and 34d. Thereby, the object Tg0 is conveyed to an area on the front end side in the extension direction (arrow SD direction) of the one free space 34d, and reaches one of the side wall surface inclined portions 83, 83 (see arrow L41). When the vibration excitation device 40 further advances and conveys the object Tg0 that has reached the one side wall surface inclined portion 83 , the object Tg0 is conveyed along the one side wall surface inclined portion 83 to a predetermined area Ap0 (see arrow L42 ). When the vibration excitation device 40 reverses and conveys the object Tg0 conveyed to the predetermined area Ap0 , the object Tg0 is conveyed to the collection unit Pu0 (see arrow L43 ). The same applies to the object T90 conveyed to the other empty space 34d of the pair of empty spaces 34d, 34d and the other side wall inclined portion 83 of the pair of side wall inclined portions 83,83.

In this way, the pair of side wall surface slopes 83 , 83 can guide the object Tg0 arrived by forward conveyance to the predetermined area Ap0 on the side of the collection unit Pu0 , similarly to the pair of corner slopes 81 , 81 . The pair of side wall surface inclined portions 83, 83 can take various forms. The pair of side wall slopes 83, 83 may be curved or flat as shown in FIG. 9 . In addition, the inclination angle of the pair of side wall surface inclined portions 83, 83 with respect to the pair of side wall surfaces 34a, 34a and the inclination angle with respect to the front end side wall surface 34b can be set arbitrarily.

Furthermore, the inclination angles of the pair of side wall surface inclined portions 83, 83 can also be defined by the positions of the third connection portion 83a connected to the side wall surface 34a and the fourth connection portion 83b connected to the top side wall surface 34b. For example, as shown in FIG. 9 , the pair of side wall surface slopes 83 and 83 may be located on the front end side of the first range Rg1 where the collection unit Pu0 is provided in the extending direction (arrow SD direction) of the conveyance path Rd0, A third connection portion 83a connected to the side wall surface 34a is provided. In addition, a pair of side wall surface inclined portions 83, 83 may be provided in the width direction (arrow WD direction) of the conveyance path Rd0 (arrow WD direction) perpendicular to the extending direction (arrow SD direction), in the second range Rg2 where the collection unit Pu0 is provided, and The fourth connection portion 83b connected to the top side wall surface 34b.

Furthermore, the guide member 80 includes, for example, a pair of corner inclined surfaces 81 , 81 and a pair of side wall inclined portions 83 , 83 . In this form, a pair of side wall surface slope parts 83 and 83 are provided between the end part 34t1 of the front-end side of the 1st range Rg1 shown in FIG. 7, and the 1st connection part 81a. Thus, the guide member 80 may include at least one pair of side wall slopes 83 , 83 among the pair of corner slopes 81 , 81 , the protruding portion 82 , and the pair of side wall slopes 83 , 83 .

2-3. The third deformation form The guide member 80 may include a pair of bottom inclined surfaces 84 , 84 . As shown in FIGS. 10 and 11 , a pair of bottom inclined surfaces 84, 84 is a pair of empty spaces 34d, 34d. Department Pu0 tilted.

For example, when the vibration excitation device 40 forwardly conveys the object Tg0 conveyed to one of the empty spaces 34d, 34d among the pair of empty spaces 34d, 34d, the direction along the extending direction of the conveyance path Rd0 (arrow SD direction) , the object Tg0 is more easily guided to the side of the acquisition unit Pu0 (see arrow L51 ). Thereby, object Tg0 is conveyed to collection part Pu0. The same applies to the object Tg0 conveyed to the other empty space 34d among the pair of empty spaces 34d and 34d.

In addition, if the inclination angle TH0 of the pair of bottom inclined surfaces 84, 84 with respect to the collection part Pu0 is constant in the first range Rg1, it is possible to easily guide the object Tg0 to the first range Rg1. It is difficult for the collection part Pu0 on the base end side to guide the object Tg0 to the collection part Pu0 on the distal side of the first range Rg1. Therefore, the pair of bottom inclined surfaces 84 , 84 may be set to increase the inclination angle TH0 relative to the collection unit Pu0 toward the tip side in the extending direction (arrow SD direction) of the conveyance path Rd0 . Thereby, it becomes easy to guide the object Tg0 evenly to the side of the collection part Pu0 in the 1st range Rg1.

Furthermore, in any case, the inclination angle TH0 can be obtained in advance through simulation, verification using a real machine, and the like. In addition, the pair of bottom inclined surfaces 84, 84 can guide all the objects Tg0 conveyed to the pair of empty spaces 34d, 34d to the side of the collection unit Pu0. Furthermore, the pair of bottom inclined surfaces 84, 84 can also guide a part of the object Tg0 conveyed to the pair of empty spaces 34d, 34d to the side of the collection unit Pu0.

When guiding a part of the object Tg0 to the side of the collection part Pu0, the guide member 80 may include, for example, a pair of corner inclined surfaces 81, 81 and a pair of bottom inclined surfaces 84, 84. In this form, the pair of corner inclined surfaces 81, 81 guides the object Tg0 not guided to the side of the collection part Pu0 by the pair of bottom inclined surfaces 84, 84 to the predetermined area Ap0. The same can be said about the other guide members 80 . That is, the guide member 80 may include at least one pair of inclined bottom surfaces 84, 84, 84.

3.
