Further, the third guide plate 35c is driven up and down in a direction orthogonal to the inclined surface 33a of the second base portion 33.

In the discharge device 50 configured as described above, the clogging of the part P1 is detected in the detecting device 40, whereby the movable block 34 is moved upward by the first driving device 51 and the third is driven by the second driving device 52 as shown in FIG. The guide plate 35c is moved upward, so that the component carrying path 30 including the inclined surface 33a of the second base portion 33, the inclined surface 34a of the movable block 34, the first guide 35a, the second guide 35b, and the third guide 35c is expanded. . Therefore, the part P1 located at the corresponding portion can be dropped into the component return passage 25 through the through-hole 33b of the second base portion 33 and the through-hole 33b of the second base portion 33, regardless of the presence or absence of clogging, and returned to the component accommodating portion 21 Inside. In addition, During the upward movement of the movable block 34 and the third guide 35c, the conveyance of the component P1 by the vibration does not stop.

The first air injection device 60 injects air to the part P1 located near the downstream end of the third guide 35c of the discharge device 50, and drops the part P1 that has not been completely removed by the discharge device 50, and as shown in FIGS. 2 and 7 The present invention includes a nozzle holder 61 fixed to the outer side surface of the return side plate 27, a linear injection nozzle 62 extending from the nozzle holder 61, and an air compressor (not shown) that transmits compressed air to the injection nozzle 62. Further, the first air injection device 60 is set to eject air from the injection nozzle 62 while the movable block 34 and the third guide 35c are moved up and down by the first drive device 51 and the second drive device 52.

The injection nozzle 62 sets the direction so that air is ejected from the downstream side of the component transport path 30 toward the upstream side toward the movable block 34 side. Therefore, if the air ejected from the ejection nozzle 62 touches the part P1, the part P1 is blown toward the movable block 34 side as shown, for example, in FIG. 7, and is bounced back by the second guide 35b attached to the movable block 34. The dropped component transport path 30 and the component drop slit 35d are dropped into the component return path 25, and returned to the component housing portion 21.

As shown in FIGS. 2 and 8 , the component transport path 30 of the second air ejecting apparatus 70 includes a third base portion 36 having a substantially trapezoidal shape, and is attached to the outer peripheral surface of the side plate 23 of the component housing portion 21; the first guide 37 Installed on the inclined surface 36a of the third base portion 36, and guides the lower surface of the lower wing Pb of the part P1; and the second guide 38 is mounted on the upper surface of the first guide 37, and the pair of parts P1 The rear end surface of the lower flap Pb is guided. Moreover, the inclined surface 36a of the third base portion 36 is oriented away from A side of the side plate 23 that is inclined downward is inclined. Therefore, the first guide 37 and the second guide 38 are inclined in the same manner as the inclined surface 36a.

The first guide plate 37 is formed with an insertion hole 37a through which the injection nozzle 72 of the second air injection device 70 to be described later is inserted, and an injection hole 37b through which the air ejected from the injection nozzle 72 passes.

Further, the second air injection device 70 is set to eject air from the injection nozzles 72 while the movable member 34 and the third guide 35c are moved up and down by the first driving device 51 and the second driving device 52. Therefore, while the movable block 34 and the third guide 35c are moving up and down, the component P1 does not enter the downstream side of the injection hole 37b of the first guide 37.

The injection nozzle 72 is disposed to be directed to the injection hole 37b of the first guide 37 after extending from the nozzle holder 71 through the insertion hole 37a of the first guide 37 into the first guide 37. Therefore, if the air ejected from the ejection nozzle 72 touches the lower surface of the lower blade Pb of the part P1, the part P1 is blown toward the side of the cover portion 74 as shown, for example, in FIG. 9, and utilizes the inside of the cover portion 74. The side surface is bounced back and dropped into the component return path 25 to return to the component housing portion 21.

In the component supply device 10 configured as described above, the clogging of the component P1 is detected in the detecting device 40, whereby the movable block 34 and the third guide 35c are moved upward by the first driving device 51 and the second driving device 52 (refer to 5 and 6), air is ejected from the injection nozzle 62 of the first air injection device 60 and the injection nozzle 72 of the second air injection device 70 (see FIGS. 7 to 9). Thereby, the component conveying path 30 of the discharge device 50 is expanded, and the part P1 located at the corresponding portion falls into the component returning path 25 with or without clogging, and the air is ejected by the first air injecting device 60, and the non-discharging device 50 The completely removed part P1 falls into the part return path 25. Further, at this time, with the air injection by the second air injection device 70, the part P1 falls into the component return passage 25 so that the part P1 does not enter the downstream side of the injection hole 37b of the first guide 37. Then, the movable block 34 and the third guide 35c are moved downward to the original position by the first driving device 51 and the second driving device 52, and the air ejection of the first air injecting device 60 and the second air injecting device 70 is stopped. .

As described above, the component supply device 10 according to the present embodiment includes the detection device 40, and is provided on the component transport path 30 in which the component P1 is arranged and transported in a predetermined posture, and detects the clogging of the component P1; The device 50 is disposed on the upstream side of the component transport path 30 than the detecting device 40, expands the component transport path 30 based on the information of the detecting device 40, and discharges the component P1 into the component housing portion 21; and the first air jet The device 60 is disposed on the downstream side of the component transport path 30 from the discharge device 50, ejects air to the component P1, and discharges the component P1 into the component housing portion 21, thereby reliably removing the clogged component P1 from zero. The conveyance path 30 is discharged.

Further, according to the component supply device 10 of the present embodiment, the second air injection device 70 is provided on the upstream side of the component transport path 30 than the discharge device 50, and is located at the component transport path. The part P1 on 30 injects air, and discharges the part P1 into the part accommodating portion 21, thereby preventing the part P1 from entering the downstream side of the second air injection device 70. Thereby, in the discharge device 50, it is possible to prevent the component P1 from being pinched by the movable block 34 and the third guide 35c which are moving downward, and clogging of the new component P1 occurs. Moreover, since the clamping of the component P1 is prevented, the damage of the component P1 can be prevented.

The present invention is not limited to the embodiments described above, and may be appropriately modified without departing from the spirit and scope of the invention.

For example, in the present embodiment, the detecting device 40 is disposed on the downstream side of the first air injecting device 60, but the arrangement position thereof is arbitrary. For example, the detecting device 40 may be disposed between the discharging device 50 and the first air injecting device 60. The device 50 is located between the second air injection device 70 and the upstream side of the second air injection device 70.
