Reference numeral 15 denotes a linear alignment rail formed on one slope in the air chamber 13, and has a width w slightly larger than the width Dw of the component D at the center of the upper surface of the alignment rail 15. The alignment groove 15a having a depth d slightly larger than the thickness Dt of the component D is formed obliquely downward. Further, a horizontal guide surface 15b for guiding the component D 1 in the throttle passage 14 to the alignment groove 15a is provided at the upper end of the alignment rail 15.

Reference numeral 16 is an air outlet formed on the side surface of the air chamber 13. Air is blown from the air outlet 16 to the upper portion of the lower end of the alignment groove 15a in a direction orthogonal to the alignment groove 15a. The air outlet 16 communicates with an air supply port 16b on the rear surface of the apparatus main body 11 via an air passage 16a, and an air supply source (not shown) is connected to the air supply port 16b.

Reference numeral 17 denotes a component passage formed in the lower portion of the apparatus main body 1, which has the same shape as the alignment groove 15a and communicates with the alignment groove 15a.

[0009]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional electronic component supply apparatus, since the bottom surface 15a1 of the alignment groove 15a forms a right angle with the vertical surface along the alignment groove 15a, the component is not in the normal posture shown in FIG. D is various abnormal postures, for example, a horizontal standing posture as shown in FIG. 8 (b), a vertical standing posture as shown in FIGS. 8 (c) and (d), and an oblique posture as shown in FIG. 8 (e). In the standing posture or the overlapping standing posture as shown in FIG. 8 (f), it is easy to enter the alignment groove 15a and remain.

The component D that has entered the alignment groove 15a in the abnormal posture can be taken out from the groove 15a and realigned by the wind pressure when the component D approaches the air outlet 16, so that the component is clogged or the supply is stopped. Although it does not reach the normal position, the probability that it will enter in the normal posture will decrease, and it will take time to align, and the component supply speed will decrease significantly.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a supply device capable of supplying rectangular flat parts at high speed.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a component storage chamber for storing a large number of rectangular flat components having a predetermined width, length, and thickness, and an air passage connected below the component storage chamber via a throttle passage. Chamber, an alignment groove that is installed in the air chamber obliquely downward to receive a component in a predetermined direction, an air outlet that blows air into the air chamber, and a component passage that communicates with the alignment groove In (1), the width and depth of the alignment groove correspond to the width and thickness of the component, respectively, and the bottom surface of the alignment groove is inclined at an acute angle with respect to a vertical surface along the alignment groove.

[0013]

[Action]

 In the electronic component feeder according to the present invention, the width and depth of the alignment groove are made to correspond to the width and thickness of the component, respectively, and the bottom surface of the alignment groove is inclined at an acute angle with respect to the vertical surface along the alignment groove. Therefore, the parts that have entered the alignment groove in a posture other than normal will lose their own weight balance and immediately fall from the alignment groove.

[0014]

【Example】

 1 to 3 show an embodiment of the present invention. FIG. 1 is a sectional view of an apparatus main body, FIG. 2 is a perspective view of an air chamber, and FIG. 3 is a sectional view of an alignment rail. In the figure, 1 is the apparatus main body, 2 is a component storage chamber, 3 is an air chamber, 4 is a throttle passage, 5 is an alignment rail, 5a is an alignment groove, 5b is a guide surface, 6 is an air outlet, and 6a is air. A passage, 6b is an air supply port, 7 is a parts passage, and D is a part. The present embodiment has the same configuration as the conventional example shown in FIGS. 5 to 7 except for the shapes of the alignment groove 5a and the component passage 7, so that the description of the other parts will be omitted to avoid duplication.

As shown in FIG. 3, the alignment groove 5a has a width w slightly larger than the width Dw of the component D and a depth d slightly larger than the thickness Dt of the component D. , Is inclined at an acute angle to the horizontal plane. The bottom surface 5a1 of the alignment groove 5a is inclined at an acute angle with respect to the vertical surface S along the alignment groove 5a, for example, at an inclination angle θ of about 45 °.

The component passage 7 has the same shape and inclination as the alignment groove 5a and communicates with the alignment groove 5a. Although not shown, the apparatus main body 1 is supported by the same base as in FIG. 4, and the component passage 7 communicates with the component passage in the base.

When air is blown into the air chamber 3 from the air outlet 6, the component D in the component storage chamber 2 is restrained from moving downward by the flow of air from the air chamber 3 toward the throttle passage 4 as in the conventional example. While being guided, it is entrained in the guide surface 15b and the air chamber 13, and is guided by the air flow into the alignment groove 5a in the posture shown in FIG. It moves through the passage 7 and the component passage in the base and is sent to the outlet.

In the above electronic component supply device, the width w of the alignment groove 5a is formed larger than the width Dw of the component D, and the depth d thereof is formed larger than the thickness Dt of the component D, and the alignment groove 5a is formed. Since the bottom surface 5a1 of the above is inclined at an acute angle with respect to the vertical surface S along the alignment groove 5a, the part D that has entered the alignment groove 5a in a posture other than the normal position, for example, a horizontal standing posture as shown in FIG. The component D that has entered the groove 5a loses its own weight balance and immediately falls from the alignment groove 5a. That is, the probability that the component D remains in the alignment groove 5a in the abnormal posture is extremely low, and the time for the component D to be aligned in the normal posture can be shortened to supply the component D at high speed.

Although the depth of the alignment groove is formed to be larger than the thickness of the component in the above embodiment, the depth may be the same as or slightly smaller than the thickness of the component. Further, the parts to be supplied are not limited to those shown in the drawings, and similar effects and effects can be obtained as long as the width is greater than the depth.

[0020]

[Effect of device]

 As described above in detail, according to the present invention, a component that has entered the alignment groove in a posture other than the normal posture is immediately dropped from the alignment groove, and the probability that the component remains in the alignment groove in the abnormal posture is extremely reduced. , The parts can be supplied at high speed by shortening the time to align them in the normal posture.
