Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a component supply device, and more particularly to a structure of a device configured to torsionally vibrate a bowl having a track extending in a spiral shape from an inner bottom portion and to move the component along the track.
[0002]
[Prior art]
Generally, vibratory parts feeders configured to supply parts by torsionally vibrating a bowl with a track extending in a spiral shape from the inner bottom and moving the parts along the track are widely used. Yes. This vibration-type parts feeder is suitable for supplying a large number of relatively small parts. In recent years, however, semiconductor IC chips, surface-mounted electronic parts, crystal vibrating pieces, etc. have become smaller and thinner. Accordingly, the importance of the parts supply apparatus is increasing.
[0003]
As a conventional typical vibratory parts feeder, the above-mentioned track has a width that is several times larger than the part width from the inner bottom of the bowl, and gradually narrows its width while extending spirally upward, The parts are gradually arranged in a line while removing the excess parts stacked on the truck. In the downstream part of the truck, a part selection area is provided to eliminate parts that are not in the normal posture among the parts arranged in a row on the truck as described above, and leave only the parts that are transported in the normal posture. It is done. This part selection area is provided with an exclusion track part configured to drop parts other than the normal posture, an exclusion mechanism for removing parts that are not in the normal attitude detected by a sensor or the like by air or the like. .
[0004]
Further, in the middle of the track, for example, a circular groove region having a concave curved track surface is partially provided in the front portion of the component selection region so that the component posture is aligned in a predetermined direction and the components are arranged in a line. There are also cases where parts are sorted out.
[0005]
[Problems to be solved by the invention]
However, in the conventional vibratory parts feeder, in the upstream part of the truck (the part close to the inner bottom part of the bowl), a large number of parts are stacked and raised, and surplus parts etc. While removing the components, the components are conveyed along the track so that the postures of the components are gradually arranged in a row, and the components are eventually fed into the component selection area. Therefore, since there is a large proportion of parts that are not in the normal posture even when the part selection area is reached, a large number of parts are eliminated in the part selection area, and there is a problem that the supply amount of parts decreases.
[0006]
Also, in the conventional vibratory parts feeder, as the number of parts stored in the inner bottom of the bowl decreases, the parts transport density on the truck decreases. However, there is a problem in that the supply amount of the components to be reduced is reduced, resulting in a shortage of component supply in a component mounting apparatus that is a component supply destination. Therefore, the inner bottom of the bowl must always contain a quantity greater than a predetermined amount. For example, parts given in lot units cannot be supplied in the normal supply amount until the end, so parts frequently In fact, it is necessary to introduce the liquid into the bowl, or the remaining parts in the bowl must be discarded.
[0007]
On the other hand, in order to secure the supply amount of the above-mentioned parts, an attempt to increase the proportion of the parts in the normal posture by increasing the round groove region for controlling the posture of the parts provided on the truck may be considered. However, if the round groove area is lengthened without changing the bowl size, the starting point of the round groove area will be extended to the upstream side, so that the parts transport capability in the upstream track part is correspondingly increased. Even if the round groove region is lengthened and the proportion of the components in the normal posture in the components supplied to the component selection region is increased, the final component supply amount is the same as the above typical example. It seems to result in not much changing.
[0008]
Therefore, the present invention solves the above-described problems, and the problem is that the amount of parts supplied can be increased as compared with the prior art, and the amount of parts supplied can be reduced even if the number of parts remaining on the inner bottom of the bowl is reduced. It is an object of the present invention to provide a novel component supply device that can suppress the decrease as compared with the prior art.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, a component supply device according to the present invention is a component supply device configured to torsionally vibrate a bowl having a track extending in a spiral shape from an inner bottom to supply a component along the track. The track has the inner bottom Gradually rises at the inverted conical inner circumference provided to surround A plurality of upstream track portions provided as described above, a junction where the plurality of upstream track portions merge, and a downstream track portion extending downstream from the junction, The inner circumferential portion is provided with an inclined track portion that extends from the upper upstream track portion and joins the lower upstream track portion to form the confluence, and extends obliquely downward in the moving direction of the component. It is characterized by.
[0010]
According to the present invention, the inclined track portion that merges from the upper upstream track portion to the lower upstream track portion is provided so as to extend obliquely downward in the traveling direction of the component, so that the merging point from the inclined track portion. The components can be smoothly moved toward the vehicle, and the components can be accelerated by the slanting downward inclination in the inclined track portion. Therefore, it is possible to smoothly increase the component conveyance density.
[0011]
Further, as described above, the parts are transported in a state where the parts are arranged in tandem on the plurality of upstream track parts, and the parts conveyance density on the upstream track part is physically limited by the tandem arrangement of the parts by joining at the junction. On the other hand, even if the parts conveyance density on the upstream track part decreases, the parts conveyance density on the downstream track part after merging is less likely to decrease due to the merging of the plurality of upstream track parts. Even if the number of parts remaining at the bottom decreases, the supply amount of parts is unlikely to decrease. Therefore, the lower limit of the remaining number of parts that can maintain the part supply amount (supply speed) within the allowable range of the supply destination can be made lower than that of the conventional structure.
[0012]
In the present invention, it is preferable that the track includes a track surface having a concave curved surface (that is, having a concave curved cross section) in at least a part of the upstream track portion. According to the present invention, the parts on the plurality of upstream track portions are controlled to have a posture corresponding to the concave curved track surface by providing a concave curved track surface in at least a part of the upstream track portion. It becomes a state arranged in a column and moves toward the confluence. The parts on the plurality of upstream track parts join at the joining point, and move on the downstream track part in a state where the parts conveyance density is increased.
[0013]
In this way, since the upstream track part has a concave curved track surface in front of the confluence, the parts are already conveyed in an almost aligned state before merging. It is possible to increase the ratio of parts to be processed, and to increase the component conveyance density at the junction, so that the supply amount of parts can be increased.
[0014]
In addition, the concave curved track surface does not come into surface contact with the component, but is in line contact or point contact, so static electricity due to friction between the track surface and the component due to torsional vibration of the bowl is less likely to occur. In addition, it is possible to reduce problems such as parts sticking to the track surface and reducing the conveyance efficiency.
[0015]
In the present invention, it is preferable that the downstream track portion in the vicinity of the merging point is provided with a concave curved surface. According to this means, the concave curved track surface is provided even if the component posture is disturbed by the merging of the plurality of upstream track portions by providing the concave curved track surface at the merging point and the downstream track portion in the vicinity thereof. Controls and adjusts the component posture and the arrangement state of the components. In addition, since the concave curved track surface is formed at the merge point, when the components on the multiple upstream track sections merge, there is enough room on the track to accept the increase in the component conveyance density due to merge. When present in an array, the parts can be smoothly joined while flexibly receiving the parts in contact with each other by the concave curved track surface, and there is not enough room to accept an increase in the parts conveyance density due to the joining. In this case, when the joined parts collide with each other (collision), one of the parts is smoothly discharged downward along the concave curved track surface without greatly disturbing the arrangement of the front and rear parts. , Excess parts can be eliminated from the track.
[0016]
In the present invention, it is preferable that a concave curved track surface is provided on at least a part of the downstream track portion. According to this means, the component posture and the component alignment state after merging can be controlled again, so that the proportion of components in the normal posture can be increased, and as a result, the final component supply amount is increased. It becomes possible.
[0017]
In this invention, it is preferable that the said upstream track part is provided with the track surface of a concave curved surface covering all from the starting point which faces the inner bottom part of the said bowl to the said confluence | merging point. According to this means, since the upstream track portion is provided with a concave curved track surface from the beginning to the end, it is possible to sufficiently control the component posture and the column arrangement state of the component row. Among them, the ratio of the parts in the normal posture can be increased, and the upstream truck part has a concave curved track surface. As a result, it is possible to increase the substantial amount of parts supplied. Further, in the upstream track portion, the effect of reducing static electricity generated between the track surface and the parts can be further enhanced.
[0018]
In this invention, it is preferable that the said downstream track part is provided with the track surface of a concave curved surface continuously from the said confluence | merging point at least to the middle. According to this means, it is possible to reduce the disturbance of the component posture and the component alignment state at the junction, and to effectively recorrect the disturbance of the component posture and the component alignment state on the downstream side. The supply amount can be further increased. In addition, the effect of reducing static electricity generated between the track surface and the component on the downstream side can be further enhanced.
[0019]
In the present invention, it is preferable that a component selection region having a substantially flat track surface for regulating the posture of the component is provided on the downstream side of the downstream track portion. According to this means, the component posture can be stabilized by the substantially flat track surface of the component selection region, and in this state, the component posture is regulated with high accuracy by providing an appropriate component selection unit in the component selection region. can do. In this case, when the concave track surface is provided in the downstream track portion as described above, the concave track surface may be provided continuously from the merging point to the start point of the part selection region. preferable. In this way, it is possible to secure a long track distance for arranging the components in a column and maintain the column arrangement state up to the component selection region, so that the proportion of components in a normal posture can be further increased. The substantially flat track surface refers to a case where a track groove having an L-shaped groove cross section or a V-shaped groove cross section is formed, for example.
[0020]
Each of the above inventions is particularly effective when transporting a rectangular parallelepiped part. When the length of the long side of the part is L, the width is W, and the thickness is T, the rectangular parallelepiped shape satisfies L> W. It is effective to use for these parts. In this case, it is particularly desirable that T is W or less. More specifically, when L is used for a part in the range of 0.5 to 5.0 mm, W is 0.2 to 3.0 mm, and T is in the range of 0.2 to 2.5 mm, the effect is particularly remarkable. It plays.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a component supply apparatus according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view of a bowl 11 of a vibratory parts feeder 10 which is a component supply apparatus according to the present invention, and FIG. 2 is a partial cross-sectional view of the bowl 11 of the vibratory parts feeder 10.
[0022]
The vibration type parts feeder 10 is formed by connecting a known vibration mechanism (not shown) for applying torsional vibration around the axis of the bowl 11 to the lower portion of the bowl 11 shown in the figure. The notch 11S provided on the outer peripheral edge of the bowl 11 shown in the figure is used in a state in which a separate conveying device such as a vibrating linear feeder is connected, for example. The illustration and description are omitted.
[0023]
The inner surface 12 of the bowl 11 includes, for example, an inner bottom portion 12a formed in a conical shape around the axis, and an inverted conical inner peripheral portion 12b formed around the inner bottom portion 12a so as to surround the inner bottom portion. It has. In the inner peripheral portion 12b, upstream track portions 13 and 14 having start points 13a and 14a facing the inner bottom portion 12a are formed in a spiral shape so as to gradually rise on the inner peripheral portion 12b. The start point 13a of the upstream track part 13 and the start point 14a of the upstream track part 14 are provided at positions that are substantially opposite to each other on the outer edge of the inner bottom part 12a (positions shifted from each other by about 180 degrees).
[0024]
The starting point 13a of the upstream track portion 13 is located at a position shifted from the starting point 14a of the upstream track portion 14 toward the component progression side, and the upstream track portion 13 is positioned above the upstream track portion 14 in the inner peripheral portion 12b. It extends in parallel with each other. Further, the upstream track portion 13 is provided with a portion that extends substantially horizontally as in the illustrated example, and the degree of advance toward the upper side is reduced compared to the portion of the upstream track portion 14 that is paralleled at the lower side. It is configured to gradually approach the upstream track portion 14 relatively gradually. Further, the upstream track portion 13 is provided with an inclined track portion 15 extending obliquely downward toward the upstream track portion 14 toward the lower upstream track portion 14 so as to join the upstream track portion 14 at the junction 16. It is configured.
[0025]
The upstream track portions 13 and 14 each have a round groove structure having concavely curved track surfaces from the start points 13a and 14a to the junction point 16. The track surface may be a concave curved surface, and may have various cross-sectional shapes such as an arc shape, an elliptical arc shape, a long arc shape, and a parabolic shape.
[0026]
The downstream track portion 17 extending first from the junction 16 is configured to extend in a spiral shape and reach the notch portion 11S. The downstream track portion 17 is provided with a round groove region 17R having a concave curved track surface similar to the upstream track portions 13 and 14 from the junction 16 to the inflection portion 17a, and downstream of the inflection portion 17a. Is provided with a flat region 17F having a flat track surface. The track surface of the flat region 17F preferably includes a support surface portion slightly inclined on the outer peripheral side of the bowl 11.
[0027]
In addition, a part selection area 17S is provided on the downstream side of the end point 17b of the flat area 17F. In the component selection region 17S, the track surface is formed substantially flat. It is preferable that the track surface of the component selection region 17S is also slightly inclined toward the outer peripheral side of the bowl 11. The parts selection area 17S is provided with a parts exclusion part 17Sa in which the track surface is rapidly narrowed. Here, a part of the parts not in the normal part posture is removed from the track surface by free fall, and the guide It returns to the inner bottom part 12a through the surface 12c. In addition, a component sorter 18 and a component limiting micrometer 19 are attached along the component sorting area 17S. The component selector 18 removes the component from the track surface by air or the like when the component is not in a normal posture by the sensor and returns it to the inner bottom portion 12a. The component limiting micrometer 19 is a component on the track surface. The height of the limiting portion is configured to be adjustable by a dial, and a part having a portion higher than a predetermined height with respect to the track surface is prevented from passing, and this is excluded from the component exclusion portion 17Sb on the track surface. It is comprised as follows.
[0028]
In the present embodiment, the components are selected and excluded only in the component selection area 17S. However, the components may be selected and excluded by an appropriate method even in the flat area 17F. Alternatively, the part selection area 17S may be connected to the end of the round groove area 17R without providing the flat area 17F. The length of the flat area 17F and the part selection area 17S ahead of the round groove area 17R can be appropriately designed as necessary, and the flat area 17F and the part selection area 17S are not provided depending on the shape of the part and the posture control mode of the part. It doesn't matter.
[0029]
FIG. 2 shows a state in which a part of the bowl 11 shown in FIG. 1 is cut. In this figure, the component selector 18 and the component limiting micrometer 19 shown in FIG. 1 are omitted. As shown in FIG. 2, the circular groove regions 17R of the upstream track portions 13 and 14 and the downstream track portion 17 are substantially perpendicular from above the bowl 11, and the tips are convex curved surfaces (spherical surface, spheroid shape, It is formed by applying a tool such as a parabolic end mill or the like to the inner peripheral portion 12 b of the inner surface 12 of the bowl 11.
[0030]
When the component P is subjected to torsional vibration on the track surface having such a round groove (convex curved surface) shape, it has a long side length L, a width W, and a thickness T as shown in the figure, and L> W and The rectangular parallelepiped-shaped part P in which W> T is satisfied is transported in a posture in which the extension direction of the track and the long side are substantially parallel and the thickness direction is substantially coincident with the vertical direction. In this case, the width of the concave curved track surface must be larger than the width W of the component P. The thickness T is preferably equal to or less than the width W. In particular, when the thickness T is smaller than the width W (that is, less than W) as described above, it is easier to control the component posture. More desirable.
[0031]
Further, when the component P has a center of gravity that is biased in the thickness direction, the surface closer to the center of gravity of the front and back surfaces of the component P due to vibration is the track surface (ie, downward). Controlled to face. For example, in the case of a component P that is transported on the track surface in a posture in which the surface closer to the center of gravity is on the upper side, the component P is rotated about an axis extending in the long side direction on the way to form a concave curved surface. The front and back are reversed on the track surface. If there is a deviation of the center of gravity in the thickness direction of the component P as described above, it is possible to more easily invert the component P by making the cross section of the track surface arc-shaped. It becomes easy to align the front and back posture. In order to easily reverse the component P, when the radius of curvature of the concave curved track surface is R, W is preferably R or more and less than 2R, particularly 1.3R or more and 1.8R or less. More desirable. If these ranges are exceeded, the part cannot be maintained on the concave curved surface, or the side of the part may exceed the concave curved surface at the time of inversion. The radius of curvature increases with respect to the width, the effect of the concave curved surface is diminished, and the part is difficult to reverse. This range is also a range in which the posture of the component with respect to the traveling direction can be satisfactorily controlled.
[0032]
In the present embodiment, by applying torsional vibration around the axis of the bowl 11 in a state where a large number of parts are accommodated in the inner bottom portion 12a of the bowl 11, the components are moved from the start points 13a, 14a on the inner bottom portion 12a to the upstream tracks 13, 14, and the long side L is directed in the extending direction of the upstream track portions 13, 14 as described above by the interaction between the weight of the part and the concave curved track surfaces of the upstream track portions 13, 14. It rises with posture.
[0033]
At this time, since the spiral diameter gradually increases as the upstream track portions 13 and 14 rise, the component conveyance density (the number of components per unit length of the track) gradually decreases. Then, the parts on the upstream track portion 13 are introduced into the inclined track portion 16 and merge with the components moving on the upstream track portion 14 at the junction 16 while being accelerated by the inclination. At this time, the inclined track portion 15 is inclined obliquely downward toward the traveling direction of the component (counterclockwise when viewed from above in the illustrated example), so that the inclined track portion 15 moves to the junction 16. The parts accelerated toward each other join the part row on the upstream track portion 14 so as to be pushed obliquely in the part traveling direction. Therefore, the parts can smoothly join, and the parts conveyance density on the downstream track portion 17 after joining can be efficiently increased.
[0034]
In addition, since the confluence 16 and the track surface in the vicinity thereof are also formed in a concave curved surface shape, when a part that merges from the inclined track portion 15 reaches the confluence 16, there are other parts at the confluence 16. When it does not exist, it is placed on the concave curved track surface and the posture is controlled smoothly. If a part already exists in the vicinity of the merging point 16, the part is pushed to the front and back of the truck to join, or Then, the part is removed from the track surface, and as a result, it is placed in a vacant position on the track surface, or it slides on another part already existing at the junction 16 and falls to the inner bottom portion 12a as it is. In any case, the smooth merging mode as described above makes it difficult for the parts row before and after the merging point 16 to be disturbed, so that the influence on the part alignment state can be reduced.
[0035]
Here, the crossing angle between the inclined track portion 15 and the upstream track portion 14 is preferably not less than 20 degrees and not more than 50 degrees. In particular, the angle is preferably 25 degrees or more and 45 degrees or less. Beyond these angular ranges, the effect of pushing in the oblique traveling direction from the inclined track portion 15 toward the merging point is diminished, so that the merging of components tends to hinder component conveyance, and smooth merging of components becomes difficult. On the other hand, if the angle is below the above angle range, as the inclined track portion 15 and the upstream track portion 14 approach each other, the partition portion between the tracks gradually decreases, and the parts easily fall over the lowered partition portion. As a result, there is an increased possibility that the upstream side of the merging point 16 merges in an unnatural posture, or that the part falls to the inner bottom portion 12a of the bowl 11 without merging.
[0036]
In the case of the present embodiment, basically, the parts are conveyed in a cascade in each of the upstream track portions 13 and 14, and the component conveyance density on the track decreases as the spiral diameter increases as the spiral track is advanced. However, by providing the merging section 16 in the middle, the parts transported on the upstream track section 13 and the parts transported on the upstream track section 14 merge. It is possible to prevent a decrease in the component conveyance density.
[0037]
Further, even when the number of parts remaining in the inner bottom portion 12a of the bowl 11 is reduced, it is possible to prevent the supply amount of the parts from rapidly decreasing. That is, the maximum value of the parts supply amount is obtained in a state where the parts moving on the downstream track portion 17 are arranged with almost no gap (in other words, the state in which the parts are arranged with almost no gap in the downstream track portion 17. However, even if the component conveyance density on each of the upstream track portions 13 and 14 is reduced, the component conveyance density of the downstream track portion 17 is unlikely to decrease due to the merging of the components. Since it is comprised, the supply amount of the components finally carried out from the bowl 11 hardly decreases with respect to the maximum value. For example, even if the individual component conveyance density of the upstream track portions 13 and 14 is half of the maximum value, the component conveyance density on the downstream track portion 17 can theoretically be maintained at a value close to the maximum value. It is possible to prevent a decrease in the amount of parts supplied.
[0038]
Furthermore, in the present embodiment, the upstream track portions 13 and 14 are provided with track surfaces on the concave curved surface from the starting points 13a and 14a, and are recessed from the junction portion 16 to the inflection portion 17a of the downstream track portion 17 as it is. Since the curved track surface is configured to continue, it is possible to control the posture of the component over a long conveyance distance, so that the regular track 17F on the downstream track portion 17 and the regular region on the component selection region 17S are used. The proportion of parts in the posture can be increased. Therefore, the final component supply amount can be greatly increased as compared with the conventional method. In this case, since the round groove structure is formed from the starting point of the upstream track portion, it is not necessary to extend the round groove structure to the outer peripheral side and shift the end point of the round groove structure to the downstream side. Even if it is not enlarged, the flat region 17F and the component selection region 17S can be formed to a sufficient length.
[0039]
Further, in the track of the present embodiment, since the portion that is the concave curved track surface occupies a large proportion as described above, the period in which the component and the track surface are in surface contact is reduced, and the component and Generation of static electricity due to friction with the track surface or the like can be suppressed. More specifically, the amount of static electricity generated can be suppressed to about 1/20 as compared with a bowl having a conventional structure. Such an effect of reducing static electricity becomes larger as a lighter and thinner part (for example, a crystal vibrating piece for a crystal oscillator) is used. This is because if a light and thin part is charged by friction with the track surface, the part sticks on the track surface due to the static electricity and easily falls into a non-transportable state.
[0040]
In addition, the component supply apparatus of this invention is not limited only to the above-mentioned illustration example, Of course, it can add various changes within the range which does not deviate from the summary of this invention. For example, the concave curved track surface only needs to be formed on each of the upstream track portions 13 and 14, thereby reducing the amount of parts transported. The amount of conveyance can be increased by merging. Further, it is more preferable that the concave curved track surface is formed only on a part of the downstream track part 17 on the downstream side of the merging point in addition to the part of the upstream track parts 13 and 14. This is because the posture of the component disturbed at the joining point can be adjusted downstream of the joining point. Furthermore, in addition to the above, the concave curved track surface is preferably formed in the vicinity of the junction. This is because, as described above, the components can be smoothly merged at the merge point, and the disturbance of the component row due to the merge can be reduced.
[0041]
In the present embodiment, specific examples and dimensions of components are not particularly described. For example, various surface mount electronic components, more specifically, chip capacitor elements (multilayer ceramic capacitors, etc.), chip inductor elements (multilayer multilayer) Ceramic inductors, etc.), resistance elements, LEDs (light emitting diodes), crystal vibrating pieces, and other various integrated circuit chips are examples of suitable transport targets when using the component supply device of the present invention. Moreover, as a component dimension, when it is a rectangular parallelepiped-shaped component, it is 3.2 * 1.0 * 1.0, 1.6 * 0.00. As dimension (mm) of length L, width W, and thickness T. 8 * 0.8, 1.0 * 0.5 * 0.5, 0.6 * 0.3 * 0.3, etc. are mentioned.
[0042]
Furthermore, in the above embodiment, an example in which two upstream track portions are provided has been described, but three or more upstream track portions may be formed. In this case, when three or more upstream track portions are integrated into a single downstream track portion, the above-mentioned merging portion is provided at a plurality of locations, and the other two or more are added to one of the three or more upstream track portions. In order to smoothly join the components, it is more preferable to sequentially (separately) join the upstream track portions.
[0043]
【The invention's effect】
As described above, according to the present invention, the supply amount of components can be increased, and a decrease in the supply amount of components can be suppressed even if the amount of components remaining on the inner bottom portion of the bowl decreases.
