Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the shape and structure of a transport body, that is, a parts container, which is mounted on an embodiment of a feeder of the present invention will be described with reference to FIGS. 1 to 3. In addition, in the description of the following embodiment, regarding the structure of the feeder other than the illustrated part holder, it is considered that a general structure in which a part holder is mounted on a conventional rotary vibration machine as shown in FIG. 6 may be adopted. The structure of the component supply device including the feeder is also the same as described above. Here, descriptions of the structures that can be generally adopted as described above are omitted.

The component receiver 61 according to the embodiment of the present invention can be integrally provided by using a metal such as aluminum, an aluminum alloy, and other materials. However, if necessary, it may be installed as follows: a sorting block 64 installed in a part sorting area provided along a part conveying path 63c to be described later, and a connecting block 65 (constituent) mounted on a part connected to a downstream device such as a linear feeder The exit 63d of the part conveying path 63c is formed as a separate component and is detachably mounted on the part holder 61 (the outer periphery), whereby it can be easily replaced by appropriate replacement and the like according to the situation. Complex structural parts.

The parts container 61 includes a mounting portion 61 a fixed to a vibration plate of a rotary vibration machine similar to the rotary vibration machine 40 shown in FIG. 6, and a bowl-shaped conveying portion 61 b provided on the mounting portion 61 a. The mounting portion 61 a is firmly and closely fixed to the above-mentioned vibration plate of the rotary vibration machine via a mounting structure such as a groove portion, using a mounting tool or the like (not shown). The rotary vibrator applies rotational vibration around the axis 61x to the component holder 61. This rotational vibration has a form of vibration that reciprocates within a predetermined minute angle range with the axis 61x as the center. In this form of vibration, it has a vibration component that moves upwards toward the axis 61x during the outward rotation in the direction of one rotation, and has an inclined downward movement during the return to the other rotation direction. The return component is a vibration component that moves downwards along the axis 61x. By applying the above-mentioned rotational vibration to the component holder 61, the components arranged inside the component holder 61 can be moved in the above-mentioned one rotation direction with the axis 61x as the center.

The conveying portion 61b has an inner bottom portion 62 and an inner peripheral portion 63 inside the container facing upward. The inner bottom portion 62 has a truncated cone shape (including a conical shape as well. The same applies hereinafter) with the axis 61x as the inner surface 62a. The inner peripheral portion 63 is provided on the outer peripheral side of the inner bottom portion 62, and is formed of a circumferential wall formed so as to surround the inner bottom portion 62 from the periphery, and has an inverted truncated cone-shaped inner surface 63a centered on the axis 61x.

Here, the height of the outer peripheral edge of the inner peripheral portion 63 is generally higher than the top of the inner bottom portion 62, but it is not particularly limited. The inner bottom portion 62 is generally set as a part storage area and is a part that accommodates a large number of parts. The inclination angle of the inner surface 62a of the inner bottom portion 62 with respect to the horizontal plane is preferably in a range of 1 ° to 10 °, and particularly preferably in a range of 3 ° to 7 °. In addition, the inclination angle of the inner surface 63a of the inner peripheral portion 63 with respect to the horizontal plane is preferably within a range of 20 ° to 80 °, and particularly preferably within a range of 30 ° to 60 °. Generally, the inclination angle of the inner surface 62 a of the inner bottom portion 62 is preferably smaller than the inclination angle of the inner surface 63 a of the inner peripheral portion 63.

In this way, even if a large number of parts are put into the inner bottom portion 62, the parts slowly move to the outer peripheral portion under the action of rotational vibration, so that excessive parts can be suppressed from being concentrated on the outer peripheral groove portion 62h described later or the outermost periphery of the part guide groove. Slot section. In addition, in the inner peripheral portion 63, by suppressing an increase in the radius when the parts conveyance paths 63b, 63c described later are measured downstream, an increase in the length of the conveyance path around the axis 61x can be suppressed, and a decrease in the conveyance density of parts can be prevented.

In this embodiment, in the outer peripheral portion of the inner bottom portion 62, first part guide grooves 62b, 62c, and 62d formed in a spiral shape around the axis 61x are formed on the inner surface 62a. In the present embodiment, a plurality of (three in the illustrated example) first component guide grooves 62b, 62c, and 62d are formed in parallel with each other. That is, in the present embodiment, a plurality of first component guide grooves 62b, 62c, and 62d in a spiral shape are formed on the frustum-shaped inner surface 62a in parallel with each other.

In the case of the illustrated example, the first part guide grooves 62b, 62c, and 62d cover the entire circumference around the axis 61x, and are formed to rotate counterclockwise from the inner peripheral side toward the outer peripheral side when viewed from above. Spiral and spiral downward. In this embodiment, the first part guide grooves 62b, 62c, and 62d are respectively formed in a predetermined angular range around the axis 61x from the start end 62bs, 62cs, 62ds to the end 62bt, 62ct, 62dt (in the example shown in the figure, A week and a half). In the illustrated example, the plurality of first-part guide grooves are formed in a shape having a rotational symmetry at a rotationally symmetrical position about the axis 61x. In addition, the plurality of first-part guide grooves 62b, 62c, and 62d are formed as a whole over the entire circumference around the axis 61x, and a plurality of (at least four in the illustrated example) groove portions are arranged adjacent to each other in the radial direction. .

In addition, a plurality of first part guide grooves are provided around the axis 61x, thereby realizing suppression of a change in the density of parts on the parts conveying paths 63b and 63c due to the offset of the parts in the inner bottom portion 62 over time. The one effect.

In addition, second component guide grooves 62e, 62f, and 62g are formed on the outer peripheral portion of the inner bottom portion 62. The second component guide grooves 62e, 62f, and 62g face the same as the first component guide groove when viewed from above. The direction is formed in a spiral shape or a spiral shape around the axis 61x. In this embodiment, a plurality of (three in the illustrated example) second part guide grooves 62e, 62f, and 62g are formed. The second part guide grooves are formed so as to extend from the start end 62es, 62fs, 62gs to the end 62et, 62ft, and 62gt within a predetermined angle range around the axis 61x (a range of 90 ° in the example shown in the figure). The range from the inner peripheral side to the outer peripheral side of the first component guide groove. In the illustrated example, the plurality of second-part guide grooves are formed in a shape having a rotational symmetry at a rotationally symmetric position about the axis 61x.

In addition, a plurality of second part guide grooves are provided around the axis 61x, thereby realizing suppression of a change in the density of parts on the parts conveying paths 63b, 63c due to the offset of the parts in the inner bottom portion 62 over time. The one effect.

The second component guide grooves 62e, 62f, and 62g are formed to intersect the plurality of first component guide grooves 62b, 62c, and 62d, respectively. Regarding the intersection of the first part guide groove and the second part guide groove, the In each of the second part guide grooves 62e, 62f, and 62g, a plurality of (three) first part guide grooves 62b, 62c, and 62d all cross. 4 (a) shows a cross-sectional shape along the line IVa-IVa shown in FIG. 1 (a), and FIG. 4 (b) shows a cross-sectional shape along FIG. 1 ( a) The cross-sectional shape of the IVb-IVb line shown.

Here, the first part guide grooves 62b, 62c, and 62d are all formed to advance in a counterclockwise direction from the starting ends 62bs, 62cs, and 62ds, and sequentially intersect with a plurality of second part guide grooves 62g, 62f, and 62e. The terminals 62gt, 62ft, and 62et of the plurality of second component guide grooves 62g, 62f, and 62e have terminals 62bt, 62ct, and 62dt at positions adjacent to the terminals in the clockwise direction.

In addition, the ends 62ft, 62gt of the second component guide grooves 62f, 62g are connected to the outer peripheral groove portion 62h, and the outer peripheral groove portion 62h is located at the outermost portion and the inner portion of the first component guide grooves 62b, 62c, and 62d. The boundary line BR between the bottom portion 62 and the inner peripheral portion 63 (see the two-dot chain line in FIG. 2). The outer peripheral groove portion 62h starts from the ends 62gt and 62ft of the second component guide grooves 62g and 62f, and passes through the groove portions of the first component guide grooves 62d and 62c located on the counterclockwise side thereof along the axis surrounding the axis 61x. The boundary line BR is intermittently provided on the inner peripheral side thereof, and finally has a terminal 62i connected to the entry port (climbing port) 63s of the part conveyance path 63b and the outer peripheral portion of the second part guide groove 62e immediately before it.

In addition, as shown by hatching in FIG. 2, the parts conveying path 63 b includes a flat conveying surface (shadow surface) and an outer side surface (a steeply inclined surface adjacent to the outer peripheral side of the shaded surface) provided on the outer peripheral side of the conveying surface. A configuration in which the conveying surface has a width wider than a width of a part in a standard attitude. The parts conveying path 63b is formed in a spiral shape in the same direction as the first parts guide grooves 62b, 62c, 62d and the second parts guide grooves 62e, 62f, and 62g (rotating counterclockwise downstream) in a plan view. However, in contrast to the first and second component guide grooves 62b, 62c, 62d, 62e, 62f, and 62g, which are downwardly spiral, the component conveyance path 63b is formed upwardly spirally.

In addition, as shown by a broken line in FIG. 2, on the downstream side of the part conveying path 63 b, a part conveying path 63 c having a narrowed conveyance surface or formed into a groove structure is provided. The difference between the upstream component conveyance paths 63b and 63c, the formation range of each conveyance path, and the like are not particularly limited to the illustrated examples. In short, in the present embodiment, the width of the parts conveying path 63b is gradually narrowed as it advances downstream from the wide entry port 63s. As a result, a component sorting mechanism configured to pass only the components in a standard posture described later through the component conveyance path 63b and gradually drop other components in different postures is provided. In addition, the part conveying path 63c is also provided with a part sorting mechanism for detecting and excluding parts in different postures, a part arrangement structure for separating and overlapping parts that overlap each other and making them merge again to form a line. mechanism.

However, as long as it passes through a part sorting mechanism for arranging the parts into a standard posture, the subsequent conveyance at the exit 63d of the part conveying path 63b, 63c, or on another conveyor provided to the exit 63d At the exit of the road, parts that are aligned in a standard attitude can be finally supplied, and the parts conveying paths 63b and 63c in this embodiment may also be arbitrarily configured.

When the rotary vibration machine is used to impart the rotary vibration about the axis 61x to the component holder 61, the component on the inner surface 62a of the inner bottom portion 62 is in the first component guide groove 62b, 62c, 62d or the second zero. The inner part guide grooves 62f and 62g advance, and further from the terminals 62bt, 62ct, 62dt, 62ft, and 62gt in the outer peripheral groove portion 62h intermittently provided along the boundary line BR or in the first part guide grooves 62d and 62c. The groove portion in the outermost periphery advances, and is finally introduced to the entry port 63s of the parts conveyance path 63b through the terminal 62i of the outer periphery groove portion 62h. In addition, the components on the inner surface 62a advance through the inside of the second component guide groove 62e, and are directly introduced from the terminal 62et to the entry port 63s of the component conveyance path 63b.

Here, all the part paths up to the entrance 63s of the part conveying path 63b via the outer peripheral edge groove part 62h of the inner bottom part 62 or the end of the second part guide groove are basically downhill, so the part easily advances in the direction in which the groove extends. However, under the effect of the above-mentioned rotational vibration, the part jumps up and the part easily leaves the bottom of the groove, so the posture of the part easily changes. On the other hand, since the parts conveying paths 63b and 63c are uphill, although the forward speed is relatively decreased, the parts are not easily detached from the conveying surface even under the effect of the above-mentioned rotational vibration, so that the posture of the parts is difficult to change. Therefore, if the parts are unified to the standard posture in the inner bottom portion 62 in advance, it is easy to maintain the standard posture of the parts without giving the posture-restricting effect to the parts conveying paths 63b and 63c.

The first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, and 62g formed on the inner surface 62a of the inner bottom portion 62 are each configured to be capable of conveying parts in a standard posture by using a groove shape described later. . In particular, the first component guide grooves 62b, 62c, and 62d can guide all components in a state of being reliably restricted to the standard posture. Thereby, a large number of parts are introduced to the entry port 63s of the parts conveyance path 63b in the above-mentioned standard posture. The part conveying path 63b has a flat conveying surface along the conveying direction and a width direction (radial direction) perpendicular to the upstream portion of the entry port 63s. Thereby, the part conveying path 63b has a plurality of width conveying paths (radial directions) and a vertical direction. The form of overlapping parts smoothly conveys a large number of parts.

As the component conveying path 63b advances in a spiral and spiral shape along the conveying direction, the parts are pushed to the outer peripheral side, thereby neatly arranging the outer peripheral conveying rows, and the width of the component conveying path 63b gradually becomes gradually smaller. Narrow, so that excess parts arranged overlapping in the width direction or the vertical direction are shaken off. The shaken part falls to the inner bottom 62 inside the boundary line BR. The parts dropped to the inner bottom part 62 are again restricted to the standard posture, and are conveyed in a counterclockwise rotation, and are introduced to the aforementioned entry port 63s.

In addition, the position where the parts from the parts conveying paths 63b, 63c fall toward the inner bottom 62 is constituted by a position (part guide groove) or a position through which the falling part is easily restricted by the attitude. It was then imported into the login port 63s. For example, a first parts guide groove 62b is adjacent to an inner peripheral side of an upstream portion of the parts conveyance path 63b near the entry port 63s. In addition, the part conveying path 63b is located on the downstream side of the conveying path portion at a position adjacent to the outer peripheral side of the terminal 62bt of the first part guide groove 62b, and the outer peripheral groove portion 62h is adjacent to the inner peripheral side. When the outer peripheral groove portion 62h advances counterclockwise, it merges with the first component guide groove 62d. In the conveyance path portion of the parts conveyance path 63b located further downstream, when the outer peripheral groove portion 62h adjacent to the inner peripheral side thereof advances counterclockwise, it merges with the first parts guide groove 62c. Therefore, the parts falling from any part of the parts conveying path 63b to the inner bottom 62 are necessarily restricted to the restrictive action of the standard posture, and are finally introduced into the entry port 63s via the terminal 62i of the outer peripheral groove portion 62h.

At the intersection, as shown in FIG. 2 (b), the inclination angle θ1 of the extending directions Fb, Fc, and Fd of the first part guide grooves 62b, 62c, and 62d relative to the tangential direction of the circle around the axis 61x is relatively large. small. In contrast, the inclination angle θ 2 of the extending directions Fe, Ff, and Fg of the second component guide grooves 62 e, 62 f, and 62 g with respect to the tangential direction of the circle around the axis 61 x is relatively large. That is, θ 1 <θ 2. Due to the difference in the inclination angle, the advancement force of the component is relatively large in the first component guide grooves 62b, 62c, and 62d, and the posture stability of the conveyed component is high. In contrast, in the second component guide grooves 62e, 62f, and 62g, the forward force of the component is relatively small, and the posture stability of the conveyed component is low. In addition, by applying the rotational vibration centered on the axis 61x to the component holder 61, a forward force is generated in a tangential direction of a circle around the axis 61x. However, it is considered that the moving direction of the component that has received the above-mentioned forward force becomes a direction that is slightly inclined to the outer peripheral side with respect to the tangential direction by the centrifugal force.

In addition, the guide distance of the parts when conveyed along the first part guide grooves 62b, 62c, 62d is long, and the guide distance of the parts when conveyed along the second part guide grooves 62e, 62f, 62g is short. Thereby, the inner bottom portion 62 is provided with a plurality of parts guide grooves having different guide speeds and guide distances. path. Accordingly, it is possible to reduce the variation in the amount of parts to be introduced into the entry port 63s due to the offset of the parts in the inner bottom portion 62 over time.

In addition, since the input of parts to the feeder is usually performed intermittently using a hopper or the like, in order to mitigate fluctuations in the input of parts, it is also important to suppress the change in the amount of parts introduced into the inner bottom 62 with time. . In addition, the first component guide grooves 62b, 62c, and 62d have a long guide distance. Since a large number of components can be thrown in at one time, the distribution of the components can be dispersed in the guide direction. It is also important on the one hand that events such as part attitudes cannot be controlled.

Furthermore, in the first component guide grooves 62b, 62c, and 62d, since the inclination angle θ1 is small and the advancing force acts in a direction close to the extending direction of the groove, the probability that the component is held in the groove is high. On the other hand, in the second component guide grooves 62e, 62f, and 62g, since the inclination angle θ 2 is large, the forward force is generated in a direction different from the extending direction of the groove, so the probability that the component is held in the groove is low. . Therefore, when there are no parts in the downstream portion of the first part guide grooves 62b, 62c, and 62d located on the counterclockwise side of the intersection, the second part guide groove 62e is formed. When parts on, 62f, and 62g are introduced into the intersection, there is a direction in which the first part guide grooves 62b, 62c, 62d (that is, a direction closer to the direction of the advancing force) advance toward the first part guide grooves downstream of the intersection. In this case, the number of components in the first component guide grooves 62b, 62c, and 62d can be increased.

As a result, since the components are effectively transferred from the second component guide grooves with a small part accommodating quantity due to the short guide distance to the first component guide grooves with a large guide accommodating quantity due to the long guide distance, The concentration of the parts into the second part guide groove with a small number of parts that can be accommodated can be eased, so that the parts can be reliably introduced into the parts conveying path 63b in a standard attitude.

However, in contrast to the above, when there are no parts in the downstream portion of the second part guide grooves 62e, 62f, and 62g located on the counterclockwise side of the intersection, when the part is in the first part guide groove When parts on 62b, 62c, and 62d are introduced into the intersection, the parts may advance toward the second component guide grooves 62e, 62f, and 62g (ie, the outer peripheral side) on the downstream side of the intersection.

In particular, in the second component guide grooves 62e, 62f, and 62g, as shown in FIG. 2 (a) and FIG. 5 (c), even at the crossing portion, the groove side portion 62s on the outer peripheral side is configured in a stepped shape. The stepped groove side portion 62s is continuous and extends toward the direction in which the groove extends. In addition, on the inner peripheral side, the groove bottom portion 62t is directly formed by a surface inclined to the upper side toward the inner surface 62a of the non-groove forming region 62k, so that the groove side portion on the inner peripheral side is not generated. Split level. Thereby, the respective parts of the first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, and 62g at the crossing portion pass the movement operation of the parts, and the movement operation of the parts between the two parts guide grooves ( In particular, the transfer operation from the second component guide groove to the first component guide groove) can be performed smoothly.

In addition, the non-groove forming region 62k refers to the inner surface 62a of the inner bottom portion 62 where the first component guide grooves 62b, 62c, 62d, the second component guide grooves 62e, 62f, 62g, and the outer periphery are formed. The inner surface area other than the part of the groove part 62h.

At the crossing portion, the stepped groove side portion 62s (see FIG. 2 (a)) on the outer peripheral side is also continuously formed in the direction in which the groove extends, so that the second component guide grooves 62e, 62f, and 62g are formed. The advancing component may reach the outer peripheral groove portion 62h or the entrance opening 63s with a short guide distance along the stepped groove side portion 62s. In this case, the part guide amount moving with the first part guide grooves 62b, 62c, and 62d along the long guide distance changes with time (corresponding to the groove extension direction in the first part guide grooves 62b, 62c, and 62d). Space fluctuations of the components), the second component guide grooves 62e, Variations in the amount of component guides in 62f and 62g can suppress variations in the amount of components introduced with respect to the component conveyance path 63b over time.

In addition, the time-varying suppressing effect can be generated by providing a plurality of first part guide grooves and second part guide grooves as described above, or by providing first parts having different shapes from each other. The guide groove and the second component guide groove are generated. Further, the guide groove and the second component guide groove can be generated by providing an intersecting portion where the component can be transferred between the first component guide groove and the second component guide groove.

In this embodiment, the parts derived from the terminals 62bt and 62dt of the first part guide grooves 62b and 62d reach the outer periphery from the terminals 62gt and 62ft via the outer peripheral portions of the second part guide grooves 62g and 62f. The edge groove portion 62h is finally introduced into the entry port 63s after passing through the aforementioned path. In addition, the parts moved only through the second part guide grooves 62f and 62g also reach the outer peripheral groove portion 62h, and are finally introduced into the entry port 63s after passing through the aforementioned path. However, the terminal 62et of the second component guide groove 62e is directly connected to the entry port 63s. In addition, the terminal 62i of the outer peripheral groove portion 62h has a groove bottom higher than the groove bottom of the terminal 62et of the second component guide groove 62e, and is located at a position directly in front of the entry port 63s from the outer peripheral side to the second The terminal 62et of the component guide groove 62e merges.

Here, the parts introduced directly from the inner peripheral side along the second part guide groove 62e and the parts introduced from the outer peripheral side through the terminal 62i of the outer peripheral groove portion 62h overlap each other in the widthwise direction, depending on the situation. Due to the difference in height between the bottoms of the grooves, the form is also overlapped in the up-down direction, and is supplied to the entry port 63s of the parts conveying path 63b. Thereby, the components adjusted to the standard posture by passing through the component guide grooves hardly change the posture, and are introduced into the entry port 63s in a state of being superposed on the width direction and the vertical direction of the component conveying path 63b. However, a part of the component derived from the terminal 62ct of the first component guide groove 62c can be introduced not only into the outer peripheral groove portion 62h, but also into the outer peripheral portion of the second component guide groove 62e.

In the present embodiment, as shown in FIG. 5 (a), the overall shape of the parts P conveyed by the parts container 61 is configured as a rectangular parallelepiped. The part P in the illustrated example is a square chip component of an SMD (Surface Mount Device). Here, the component P has a shape extended in the left-right direction in FIG. 5. The length PL of the extension direction E of the component P is larger than any one of the width PW and the thickness PT in a direction perpendicular to the extension direction. In the example shown, PL> PW> PT. At this time, the value of the thickness PT is the smallest and is less than half with respect to any one of the length PL and the width PW. Therefore, regardless of the orientation of the extension direction E described above, the The posture of the part P is actually any one of the posture of the illustrated example and the posture after the posture is turned inside out.

In the present embodiment, the standard posture of the component P is a posture that makes the extension direction E coincide with the conveyance direction of the component conveyance path 63b. When the positive and negative directions of the extension direction E are considered, the inside and outside are reversed. In total, there are four postures. In addition, there are twelve types of conveying postures of the part P. However, since the thickness PT is small, when considering only the posture in which any one of the illustrated inner and outer surfaces are opposed to the conveying surface or the bottom of the groove, In fact, a total of eight postures can be adopted.

In the inner bottom portion 62, the part P passes from the inner peripheral side of the guide groove forming area where the first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, and 62g are formed. After the above-mentioned guide groove forming area around the entire circumference of the axis 61x, the outer peripheral groove portion 62h or the outermost groove portion of the first part guide grooves 62d and 62c along the inside of the boundary line BR is finally introduced into the part. The entrance 63s of the conveyance path 63b.

In addition, the component P is configured to pass only through the non-groove forming area 62k, and cannot pass from the inner periphery of the formation area compared to the first component guide grooves 62b, 62c, 62d and the second component guide grooves 62e, 62f, 62g. The side reaches the entrance 63s of the parts conveyance path 63b. That is, in the formation area of the first component guide grooves 62b, 62c, 62d and the second component guide grooves 62e, 62f, and 62g provided in the outer peripheral portion of the inner bottom portion 62, There is no non-groove forming region 62k through which the component P can pass. More specifically, there is no gap region between the first component guide grooves 62b, 62c, 62d and the second component guide grooves 62e, 62f, 62g and the width PW or more that the component P can actually pass through. In addition, strictly speaking, there may be a case where the gap between the component guide grooves is larger than the above-mentioned thickness PT. However, since the gap is formed to be long and within a range of several weeks of the first component guide groove, the component P is actually impossible. Passed without falling to the first part guide groove.

Further, in the present embodiment, as described above, the first component guide groove and the second component guide groove intersect, so that the gap itself does not extend from the inner peripheral side of the inner bottom portion 62 to the outer peripheral edge groove portion 62h or the entry port 63s. The range has been continuous. Thereby, it is possible to prevent the parts P that are not subjected to the attitude restriction action of the first parts guide grooves 62b, 62c, 62d and the second parts guide grooves 62e, 62f, and 62g from being introduced into the parts conveying path 63b.

Next, a groove structure of the first component guide grooves 62b, 62c, and 62d for making the above-mentioned component P into a standard attitude will be described. As shown in FIG. 5 (b), the first part guide grooves 62b, 62c, and 62d have a groove bottom portion 62p and groove side portions 62q and 62r provided on both sides in the width direction of the groove bottom portion 62p (refer to the first zero in the figure). The component guide groove 62d is marked with a symbol), wherein the groove bottom portion 62p has a length PL narrower than the above-mentioned extension direction E of the component P and wider than the width PW of the component P.

The groove bottom 62p has a surface shape corresponding to the bottom surface of the component p in the standard posture shown in FIG. 5 (a), and is a flat surface in the example shown in the figure. In the illustrated example, the groove bottom portion 62 p is formed in a horizontal plane. Further, the inner side surfaces of the groove side portions 62q and 62r constituting the outer peripheral side (lower side) and the inner peripheral side (upper side) of the groove bottom portion 62p are formed as inclined surfaces that are inclined with respect to the groove bottom portion 62p and face obliquely upward. Here, the surface boundary between the groove bottom portion 62p and the groove side portions 62q, 62r is discontinuous, but has a zigzag discontinuous surface boundary whose boundary line can be clearly identified. In the example shown in the figure, the inner surfaces of the groove side portions 62q and 62r are inclined surfaces that are inclined by about 40 ° to 50 ° with respect to the horizontal plane. The inner surface is preferably a flat inclined surface.

With the above configuration, once the parts P1 (see the first part guide grooves 62b and the first part guide grooves 62c on the left in the figure) disposed inside the first part guide grooves 62b, 62c, and 62d in a standard posture are shown. The contact area between the outer surface of the groove and the groove bottom portion 62p opposite to it increases, and the boundary between the groove bottom portion 62p and the groove side portions 62q and 62r is a ridge-shaped discontinuous surface boundary formed by the meandering of the surface. Therefore, it is difficult for the part P1 to climb up the groove side portions 62q, 62r, thereby improving the posture stability of the part P1 in the standard posture.

On the other hand, the parts P2 (see the symbol marked on the first part guide groove 62b on the left in the figure) in a different posture in a non-standard posture are separated from the groove bottom 62p because the extension direction E is in the width direction. Gesture. That is, the end of the above-mentioned extension direction E of the part P2 or its vicinity will climb on the inclined surface of the groove side portions 62q, 62r or on the inner surface 62a outside the groove, and the outer surface of the part P2 becomes separated from the groove bottom 62p. In this state, the posture of the part P2 is extremely unstable. Therefore, the attitude of the part P2 is not durable, and it is easy to change to the above-mentioned standard attitude under the action of the above-mentioned rotational vibration. In addition, by forming the groove side portions 62q and 62r as inclined surfaces, parts in different postures can easily be changed to a standard posture, and external parts arranged on the non-groove forming area 62k can enter the parts smoothly. Inside the guide slot.

In addition, the grooves on the inner bottom described in the above-mentioned Patent Documents 1 or 3, and the inner surface of some of the grooves are formed into a concave curved surface as a whole, and some of the grooves extend from the bottom of the groove to the groove side portion (especially the groove side portion on the outer peripheral side) The contour of the part is formed by a continuous curved surface. Therefore, the corners of the part P are in point contact or line contact with the inner surface of the groove, and the position of the contact point is also easily changed. Therefore, the posture of the part P is unstable when subjected to the above-mentioned rotational vibration. . Therefore, if the groove portion is provided as described above, the posture of the component P is easily changed. In addition, in the conventional parts container 41 shown in FIG. 6, a so-called groove 42 b called a “sucking groove” is formed in the inner bottom portion 42. but, Such a groove 42b only moves the part P from the inner peripheral side toward the outer peripheral side, and the posture of the part P introduced into the entrance of the part conveying path 43b is scattered.

According to the first component guide grooves 62b, 62c, and 62d of the above-described structure of the present embodiment, all of the parts P entering the grooves have the above-mentioned standard attitude. Specifically, a part of the part P that has entered the groove in a different posture is transformed into a standard posture in a short time by the above-mentioned rotational vibration. In addition, once the parts P accommodated in the first part guide grooves 62b, 62c, 62d in a standard posture, even if subjected to the above-mentioned rotational vibration, there is almost no case where they fly out of the groove or change to a different posture. Therefore, a large number of parts are moved to the downstream side (outer peripheral side) along the extending direction of the groove while maintaining the standard posture. In addition, when the variation of the supply amount of the component with respect to the component container 61 is suppressed to a certain extent, all the components P introduced into the entry port 63s of the component conveyance path 63b can be configured to have a standard attitude.

The groove structure of the second component guide grooves 62e, 62f, and 62g is shown in FIG. 5 (c), and the groove side portion 62s on the opposite side (that is, the outer peripheral side) of the axis 61x is configured in a step shape. In addition, the groove bottom portion 62t is inclined toward the upper side of the side so as to gradually approach the inner surface 62a of the non-groove forming area 62k from the groove side portion 62s side (outer peripheral side) toward the opposite side (inner peripheral side), and finally A ridge-like boundary is formed on the groove side portion on the axis 61x side (inner peripheral side) with a minute surface angle difference from the inner surface 62a of the non-groove forming region 62k. That is, the structure of the second component guide grooves 62e, 62f, and 62g is such that a stepped portion is provided in the groove side portion 62s on the outer peripheral side, but the groove side portion on the inner peripheral side has only a ridgeline of a surface boundary without With split levels.

Further, in the second component guide grooves 62e, 62f, and 62g, similarly to the above-mentioned first component guide grooves, a zigzag configuration is provided between the groove side portion 62s on the outer peripheral side and the groove bottom portion 62t. Edged discontinuity boundary. Thereby, the conveyance posture can be stabilized in a state where the component P and the groove side portion 62s can abut.

In the second component guide grooves 62e, 62f, and 62g having the above-mentioned structure, as described above, when the above-mentioned groove side portions 62s are continuously arranged across the entire length of the groove, the amount of the deviation is as follows: that is, The inner peripheral portion of the second component guide groove or the intersection with the first component guide grooves 62b, 62c, 62d is low, and the gap portion between the first component guide grooves or the second portion between the intersections is low. The outer periphery of the part guide groove becomes deeper. However, it may be configured differently from the above case, and the stepped portion of the groove side portion 62s may not exist in the crossing portion. In either case, in the second component guide grooves 62e, 62f, and 62g, the components can be restricted to a standard posture in which the extension direction E is directed toward the extension direction of the groove.

However, the groove structure of the second part guide grooves 62e, 62f, and 62g is as described above, and since the groove side portion on the inner peripheral side is not provided with a staggered layer, there is a possibility that the groove width becomes large enough to approach the part. The inner peripheral part or outer peripheral part of the length PL of the length direction E of the P in the above-mentioned extending direction decreases the restricting effect on the posture of the part P, or when a large number of parts P flow into the second part guide groove, etc. The parts P are in contact with each other and the posture of the parts P is disturbed.

The main parts of the first part guide grooves 62b, 62c, and 62d near the start ends 62bs, 62cs, 62ds or the terminals 62bt, 62ct, and 62dt and the main peripheral groove part 62h can be configured as the second part guide grooves. The above-mentioned cross sections of 62e, 62f, and 62g have the same cross-sectional structure.

By mounting and fixing the component holder 61 configured as described above to a rotary vibrator and imparting the above-mentioned rotary vibration, a large number of components P on the inner surface 62a of the inner bottom 62 are put into the feeder of this embodiment. The first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, and 62g are restricted to a standard attitude along the extending direction of the groove, and reach the outer peripheral edge groove portion 62h or the first zero on the outer peripheral side. The outermost groove portion of the component guide grooves 62d and 62c or the outer peripheral portion of the second component guide groove 62e is finally introduced into the entry port 63s of the component conveyance path 63b in a standard posture. At this time, the login port 63s Since the parts P are almost all in a standard attitude, a large number of the parts P are conveyed along the parts conveying path 63b in a state in which the parts P are superposed in the width direction or the up-down direction.

When the parts conveying path 63b is conveyed while being subjected to the above-mentioned rotational vibration, if there is a gap in the conveying direction between the parts in the outer peripheral conveying row of the parts arranged on the outermost peripheral side, the width or The parts overlapping in the vertical direction are arranged in such a manner that they enter the gap from the inner peripheral side or the upper side. In addition, since the width of the part conveying path 63b gradually narrows toward the downstream side, the number of parts P on the redundant part conveying path 63b other than the outer peripheral conveying row gradually decreases as the parts fall from the conveying surface through the conveying surface. . At this time, as described above, almost all the parts P are introduced into the part conveying path 63b in a standard attitude. Therefore, even when the alignment on the outer peripheral side conveying line is in progress, the parts on the part conveying path are as described above. It is also difficult to cause a change in attitude, and therefore, almost all the parts P in the above-mentioned outer peripheral side transport line maintain a standard attitude.

That is, even if the part is inserted into the outer peripheral side conveying row of the part under the above-mentioned rotational vibration, the structure of the conveying path of the part conveying path 63c (for example, the width of the local conveying surface is narrowed, or The structure on the conveying surface is staggered) so that the overlap of the parts P in the width direction or the up-and-down direction is eliminated. In the conveying column of the remaining arrangement state of the parts P, almost only the parts in the standard posture are left. The part P hardly exists.

Therefore, even when passing through the sorting area for excluding parts with other postures provided on the subsequent conveying path such as the parts conveying path 63c or a linear feeder downstream thereof, the conveying line of the arrangement state of the parts P also becomes It is difficult to generate voids, so that the high conveyance density of the component P can be maintained, and the conveyance speed can be increased.

In addition, in fact, the redundant parts P arranged in such a manner as to overlap the inner peripheral side or above with respect to the outer peripheral side conveying line are compared with the parts P in the outer peripheral side conveying line because The contact amount of the surface or conveying side is small, so the posture stability is low. Therefore, if the redundant part P is stored in the middle of transportation for a long period of time, the standard posture may be changed to another different posture due to some reasons, and it may be introduced into the outer peripheral side transportation column on the downstream side of the component transportation path. In this case, the effect of this embodiment will be significantly hindered. In order to avoid this, the parts conveying paths 63b and 63c need to be provided with a parts arranging mechanism from the upstream side as in the past.

In the past, the parts-based arrangement function has always been realized by the parts conveying paths 43b and 43c. As long as the suction groove 42b formed in the inner bottom 42 can supply a large number of parts to the entry port of the parts conveying path 43b, This idea can be used to design the previous parts receiver 41. However, in the present embodiment, the parts P are made into a standard posture on the inner bottom portion 62, and a large number of parts P are supplied to the entry port 63s of the parts conveying path 63b in a state of being piled up in a substantially standard posture. This makes it possible to increase the conveyance density of the parts when they finally pass through the parts conveyance paths 63b and 63c in an aligned state, and to make them higher than before. Thereby, by reducing the number of parts to be excluded during the supply, the supply speed of the parts can be increased. In this embodiment, it is also possible to make the supply speed of the parts about 1.5 times as high as before.

In addition, when it is desired to supply only the parts P having a standard attitude as shown in FIG. 5 (a), it is preferable to change the attitude instead of excluding parts P having another standard attitude opposite to the inside and outside. That is, on the parts conveying path 63b, 63c in the case of a feeder, on the parts conveying path 63b, 63c in the case of a part feeding device, or on a subsequent conveying path of another conveyor such as a linear feeder, the conventional The attitude reversing mechanism and the like may be supplied by converting the parts in the other standard attitude into the standard attitude shown in the figure. In this way, it is possible to further suppress a decrease in the final transport density.

In the present embodiment, the component P supplied through the second component guide groove 62e with respect to the entry port 63s of the component conveyance path 63b is introduced from a lower position on the inner peripheral side, and is guided from the first component guide groove. The component P supplied from the terminal 62ct of the 62c or the outer peripheral groove portion 62h is introduced from a high position provided on the outer peripheral side of the terminal 62i. At this time, both the part P introduced from the inner peripheral side (lower position side) and the part P introduced from the outer peripheral side (higher position side) are restricted to assume a standard posture. In this way, the parts P, which are restricted to the standard posture on the inner peripheral side (lower position side) and the outer peripheral side (higher position side), are introduced into the entry port 63s. Therefore, the parts P are introduced in line with the parts P while being introduced. Compared with the case of the direction, the posture of the part P during introduction is difficult to change, and a large number of parts P can be introduced in the width direction and the up-down direction of the part conveying path 63b, thereby improving the upstream of the part conveying path 63b. The part's transport density. Therefore, in order to cope with a decrease in the transport density and the like on the downstream side in the parts transport path 63b, the transport density of the parts P in the upstream portion can be increased in advance.

In the illustrated example, two part paths are merged at the entry port 63s, but three or more part paths may be merged. In addition, it is also possible to introduce a large number of parts into the entry port 63s through the confluence of the parts paths of the inner and outer peripheral sides of the same height, with overlapping states in the width direction, or to form a plurality of groove bottoms by forming a trench structure, etc. The part paths located in the vertical relationship in the vertical direction, and through the confluence of these part paths, a large number of parts are introduced into the entry port 63s through the form of overlapping in the up and down directions.

In the present embodiment, the first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, and 62g are respectively located at mutually different positions around the axis 61x (from the start to the end of the azimuth or angle). Range), or by providing first part guide grooves 62b, 62c, 62d and second part guide grooves 62e, 62f, 62g having different configurations (lead angles or forming ranges) from each other. In addition, the first part guide grooves 62b, 62c, and 62d and the second part guide grooves 62e, 62f, and 62g that cross each other are provided, and the crossing part is configured to be able to pass through the same part guide groove or transfer to Different parts guide grooves can improve the above-mentioned conveying density, and can suppress the A case where the component introduction amount with respect to the component conveyance path 63b varies with time due to a component offset or the like on the inner surface 62a. In particular, the first part guide grooves 62b, 62c, 62d and the second part guide grooves 62e, 62f, 62g have different guide distances, guide speeds, guide directions, groove structures, etc. through each other, which can further improve the aforementioned Inhibition of time changes.

In addition, in the present embodiment, a plurality of parts paths each supplying parts in a state of a standard posture are merged at a position adjacent to the entrance 63s of the parts conveying path 63b in front of each other. When parts are introduced into the entry port 63s of the parts conveying path 63b, the parts can be supplied to the parts conveying path 63b in a state in which the parts are kept intact and the parts are overlapped with each other without changing the position of the parts. That is, a large number of parts can be supplied onto the part conveying path 63b without disturbing the standard posture of the parts restricted by the part guide grooves.

Furthermore, in the present embodiment, in the first and second component guide grooves, groove bottom portions 62p and 62t having a surface shape capable of contacting the outer surface of the component in a standard posture through at least one side (outer peripheral side) ) The groove side portions 62q, 62r, and 62s have discontinuous surface boundaries, and in particular, it is possible to avoid the cause and cause of the formation of a continuous surface structure between the groove bottom portion and the groove side portion on the outer peripheral side. Since the posture stability of the part separated from the bottom of the groove is reduced and the posture stability of the part in the standard posture can be improved, the part can be reliably restricted to the standard posture and introduced into the part conveying path 63b.

In addition, in the present embodiment, a guide groove forming region is provided on an outer peripheral portion of the inner bottom portion 62, and the guide groove forming region is transmitted through the inner peripheral portion of the inner bottom portion 62 and along the boundary between the inner bottom portion 62 and the inner peripheral portion 63. The first and second component guide grooves are formed between the outer circumferential edge groove portions 62h of the wire BR. In this guide groove formation area, first and second component guide grooves are formed so that there is no non-groove formation area 62k through which the component P can pass. Therefore, if the part P is not restricted to the standard posture by the first and second part guide grooves If it can, it will not reach the outer peripheral groove portion 62h or the entry port 63s, and as a result, it will not be guided into the parts conveyance path 63b. Therefore, only the parts P restricted to the standard posture through the first and second parts guide grooves are introduced into the parts conveying path 63b. Therefore, it is possible to further suppress the occurrence of the parts P in the downstream portion of the parts conveying path 63c. The transport density is reduced, and the effect of increasing the supply speed of the parts P can be further enhanced.

In addition, the parts accommodator and feeder of the feeder of the present invention are not limited to the configuration of the embodiment described above, and various modifications can be made as long as they are within the technical idea of the present invention.
