Japanese Patent No. 3088742 JP 2002-353694 A

  However, in the conventional method as shown in Patent Document 1, since the direction of the workpiece is changed to the series one by one, when changing the direction of a large number of workpieces, there is a problem that it takes time and increases the cost. is there.

  In the conventional method as shown in Patent Document 2, it is necessary to prepare one suction nozzle for one workpiece, and since a certain amount of space is required between the suction nozzles, the apparatus itself is large. In addition, there is a problem that costs for maintenance of the apparatus must be taken into consideration, which also leads to an increase in cost.

  The present invention has been made in consideration of such problems, and can change the direction of a large number of workpieces at once with a simple configuration, thereby reducing the cost of a workpiece production line and improving productivity. An object of the present invention is to provide a tray jig that can be used.

A tray jig according to the present invention includes a first tray having one or more first openings on a main surface, and a second tray having one or more second openings on a main surface. A tray jig for transferring a work from the first tray to the second tray by stacking the surface and the main surface of the second tray facing each other,
The second opening of the second tray is an opening of a recess formed in the second tray;
Of the bottom of the recess, a workpiece placement surface is formed in a portion facing the first opening when the first tray and the second tray are overlapped,
The workpiece placement surface is formed at a position lower than the bottom of the recess.

  The direction of the workpiece can be changed as follows.

(1) Arrange each workpiece in the first opening of the first tray.

(2) Cover the second tray so that the main surface of the second tray overlaps the main surface of the first tray.

(3) Reverse the top and bottom of the superimposed first tray and second tray. That is, the first tray is positioned over the second tray by turning 180 °. At this time, the work is placed on the work placement surface of the second tray.

(4) Remove the first tray facing upward. At this time, the work is in a shape standing on the work placement surface. Then, by giving vibration to the second tray, the workpiece is easily tilted toward the intended direction, that is, the bottom of the recess, and the direction of the workpiece is changed.

  Accordingly, by providing a large number of openings in the first tray and the second tray, the direction of a large number of workpieces can be changed at a time, and the cost of the workpiece production line can be reduced and the productivity can be improved. .

And in the present invention, when the length in the width direction of the surface of the workpiece facing the workpiece placement surface is W, and the length in the width direction of the workpiece placement surface is w,
W <w <2W
Is preferably satisfied. If W ≧ w, the workpiece does not enter the workpiece mounting surface. When w ≧ 2W, when the work is tilted, even if the work falls in an unintended direction or falls in the intended direction, variation in the position of the work after falling becomes large.

Further, in the present invention, when the height of the inner wall surface that determines the outer end of the workpiece placement surface among the recesses is d1, and the height of the workpiece is H,
H / 5 <d1 <2H
Is preferably satisfied. If 1 / 5H ≧ d1, the workpiece may fall in an unintended direction and cannot be employed. If d1 ≧ 2H, there is a problem that it is difficult to take out the workpiece in the next step. That is, as a method for taking out the workpiece in the next process, a method by tray inversion, a method by vacuum suction, or the like can be considered. When d1 ≧ 2H, in the case of tray reversal, when the work is transferred from the second tray to another tray by tray reversal, the work may be reversed or rotated 90 °. In the method using vacuum suction, there is a problem that after the workpiece is vacuum-sucked, the distance that must be moved in the vertical direction before moving in the horizontal direction is increased, and the time required for taking out and moving the workpiece is increased.

  Further, in the present invention, a taper portion is formed at a peripheral edge portion of the first opening, and an inclination angle of the taper portion with respect to the width direction is a central angle of 1 ° or more extending from the opposing taper portion, 45 It may be set to be less than or equal to °. In this case, when each work is put into the first opening of the first tray, it can be easily put in, and the time can be effectively shortened.

  In the present invention, a taper portion may be formed in a peripheral edge portion of the peripheral edge portion of the second opening that faces an inner wall surface that determines an outer end of the workpiece placement surface. In this case, even if the opening width of the second opening along the one direction is narrowed, the corner portion of the workpiece does not collide with the peripheral edge of the second opening, and the workpiece is damaged smoothly. And the workpiece can be dropped into the second opening.

  In the present invention, the first opening of the first tray may be an opening of a recess or a through hole formed in the first tray. In particular, when the through hole is used, the direction of the workpiece can be changed by the following procedure, and the number of man-hours can be reduced.

(1) Cover the first tray so that the main surface of the first tray overlaps the main surface of the second tray.

(2) Insert a workpiece into each through hole of the first tray. At this time, the workpiece is placed on the workpiece placement surface of the second recess.

(3) Remove the first tray facing upward. Then, by applying vibration to the second tray, the workpiece is easily tilted toward the intended direction, that is, the bottom of the second recess, and the direction of the workpiece is changed.

  Moreover, in this invention, you may make it have the hole for air blowing which has an opening in the said workpiece | work mounting surface, and the hole for air suction which has an opening in the bottom part of the said recessed part. By blowing air through the air blowing hole and sucking air through the air sucking hole, the rotation of the workpiece is promoted, and the workpiece easily falls in the intended direction, that is, toward the bottom of the second recess, The direction of will be changed. In this case, since the work can be forcibly rotated, the direction of the work can be easily changed.

  Moreover, in this invention, you may make it have a processus | protrusion on the said workpiece | work mounting surface. In this case, inconveniences such as missing corner portions of the workpiece can be avoided.

  In the present invention, at least the corners of the steps that determine the inner end of the workpiece placement surface may be chamfered. Also in this case, it is possible to avoid inconveniences such as part of the workpiece being missing.

  As described above, according to the tray jig according to the present invention, the direction of a large number of workpieces can be changed at a time with a simple configuration, thereby reducing the cost of the workpiece production line and improving the productivity. be able to.

  Hereinafter, embodiments of a tray jig according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the tray jig 10 according to the present embodiment includes a first tray 16 having one or more first openings 14 on the main surface 12 and one or more second openings 20 on the main surface 18. And a second tray 22. Two or more positioning holes 24 are formed on the first tray 16, and positioning pins or protrusions 26 are formed on the second tray 22 at locations corresponding to the positioning holes 24. Of course, two or more positioning pins or protrusions 26 may be formed on the first tray 16, and two or more positioning holes 24 may be formed on the second tray 22.

  The first opening 14 of the first tray 16 is an opening of a first recess 28 formed in the first tray 16 as shown in FIGS. 2A and 2B. A work 30 having a cubic shape or various columnar shapes is inserted. The first recess 28 includes a recess main body 28 a in which the work 30 is accommodated and a tapered portion 28 b formed at the peripheral edge of the first opening 14.

  Moreover, as shown in FIG. 3A, when the first opening 14 is viewed from the upper surface, of the recess main body 28a along the width direction (X direction) among the directions along the two center lines (X direction and Y direction). The opening width D1 is set to be larger than the length W of the workpiece 30 in the width direction. In FIG. 3A, the length of the workpiece 30 in the Y direction is set to be larger than the X direction (width direction), but the length in the Y direction and the length in the X direction may be substantially the same, although not shown. The length in the Y direction may be smaller than the length in the X direction.

  The 2nd opening 20 of the 2nd tray 22 is an opening of the 2nd crevice 32 formed in the 2nd tray 22, as shown, for example in Drawing 2A. As shown in FIG. 3B, the opening width D2 along the width direction (X direction) of the two openings 20 along the center line (X direction and Y direction) when the second opening 20 is viewed from above is the workpiece width. It is set to be larger than a height H of 30 (see FIG. 2A). The depth h of the second recess 32 (the distance from the position of the main surface 18 of the second tray 22 to the bottom 32b of the second recess 32) is set to be greater than the length W of the workpiece 30 in the width direction.

  A work placement surface 34 is formed in the second recess 32. The workpiece placement surface 34 is formed at a position lower than the bottom 32b of the second recess 32. For example, as shown in FIG. 2A, the main surface 12 of the first tray 16 and the main surface 18 of the second tray 22 are formed. And the positioning holes 24 (refer to FIG. 1) of the first tray 16 and the positioning pins or protrusions 26 (refer to FIG. 1) of the second tray 22 are matched (that is, the first tray 16 is aligned). When the tray 16 and the second tray 22 are overlapped with each other, the positional relationship is such that the concave body 28a of the first concave portion 28 faces each other.

  Here, how to use the tray jig 10 will be described.

(1) Insert the workpieces 30 into the first recesses 28 of the first tray 16.

(2) The second tray 22 is covered so that the main surface 12 of the first tray 16 and the main surface 18 of the second tray 22 overlap each other. Here, “superimpose the main surface 12 of the first tray 16 and the main surface 18 of the second tray 22” means that the main surface 12 of the first tray 16 and the second tray 22 are overlapped as shown in FIG. 2A. This includes the case where a gap is formed between the main surface 18 and the case where the main surface 12 of the first tray 16 and the main surface 18 of the second tray 22 are in contact with each other as shown in FIG. 2B.

(3) The top and bottom of the superimposed first tray 16 and second tray 22 are reversed.

  In other words, the first tray 16 is reversed 180 ° so that the first tray 16 is positioned on the second tray 22 as shown in FIGS. 2A and 2B. At this time, the work 30 inserted into the first recess 28 of the first tray 16 falls onto the work placement surface 34 of the second tray 22.

(4) As shown in FIG. 2C, the first tray 16 is removed facing upward.

  At this time, the workpiece 30 stands on the workpiece placement surface 34. In this case, the height (first step d1) of the first inner wall surface 32a of the second recess 32 that determines the outer end of the workpiece placement surface 34 is larger than the second step d2 that determines the inner end of the workpiece placement surface 34. Therefore, by applying vibration to the second tray 22, the workpiece 30 is easily tilted toward the intended direction, that is, toward the bottom 32 b of the second recess 32. In the example of FIG. Is changed by 90 °, and the surface 30a facing the first inner wall surface 32a of the second recess 32 of the workpiece 30 faces upward. In addition to the method of applying vibration to the second tray 22 as described above, the method of tilting the work 30 includes a method of applying an impact to the second tray 22 and a method of tilting the second tray 22.

  As described above, in the tray jig 10, the first tray 16 and the second tray 22 are provided with the multiple first openings 14 and the second openings 20, thereby changing the direction of the multiple workpieces 30 at a time. Thus, the cost of the production line for the workpiece 30 can be reduced and the productivity can be improved.

  Here, the configuration and problems of the tray jig 100 according to the comparative example devised in the manufacturing process of the tray jig 10 according to the present embodiment will be described.

  As shown in FIG. 4A, the tray jig 100 according to the comparative example has the work placement surface 34 at the same position as the bottom 32 b of the second recess 32, and the entire bottom 32 b of the second recess 32 is one flat. It is a surface.

  In this case, as shown in FIG. 4B, after removing the first tray 16, vibration is applied to the second tray 22, so that the direction of the work 30 is changed by 90 °, and the second recess 32 of the work 30 is The surface 30a (for example, the front surface) facing the inner wall surface 32a faces upward, or the surface 30a (front surface) faces downward as shown in FIG. The inconvenience that the front and back of the workpiece 30 differs depending on the location.

  On the other hand, in the tray jig 10 according to the present embodiment, the position of the workpiece placement surface 34 is present at a position lower than the bottom 32b of the second recess 32, and a step (work placement) is placed on the bottom 32b of the second recess 32. Therefore, the workpiece 30 can be prevented from falling in an unintended direction, and the workpiece 30 can be tilted in one direction. Thereby, in the 2nd tray 22, the surface (surface 30a which faced the 1st inner wall surface 32a of the 2nd crevice 32) of all the works 30 faces upwards. Thus, the front and back of the work 30 after the direction change does not differ depending on the place, and the front and back of all the work 30 after the direction change are aligned.

  Next, the preferable aspect of the tray jig | tool 10 is demonstrated, referring FIGS.

(A) As described above, it is preferable to form the tapered portion 28b at the peripheral edge portion of the first opening 14 (see FIG. 2A). As shown in FIG. 5, the inclination angle of the tapered portion 28b in the width direction (X direction) is set so that the central angle θ of the center 28c obtained by extending the opposing tapered portion 28b is 1 ° or more and 45 ° or less. It is preferable. Thereby, when putting each workpiece | work 30 in the 1st opening 14 of the 1st tray 16, it can put in easily and shortening of the time concerning insertion work can be aimed at effectively.

(B) When the length in the width direction of the surface (lower surface) facing the workpiece placement surface 34 of the workpiece 30 is W, and the length in the width direction of the workpiece placement surface 34 is w,
W <w <2W
Is preferably satisfied. If W ≧ w, the workpiece 30 does not enter the workpiece placement surface 34. If w ≧ 2W, even if the workpiece 30 tilts in an unintended direction when the workpiece 30 is tilted or falls in the intended direction, the position of the workpiece 30 after falling (the lower surface of the workpiece 30 and the first inside Variation in the distance between the wall surfaces 32a and the like) increases.

(C) When the height of the first inner wall surface 32a that determines the outer end of the workpiece placement surface 34 in the second recess 32 is d1, and the height of the workpiece 30 is H,
H / 5 <d1 <2H
Is preferably satisfied.

  If 1 / 5H ≧ d1, the workpiece 30 may fall in an unintended direction and cannot be employed.

  If d1 ≧ 2H, there is a problem that it is difficult to take out the workpiece 30 in the next step. That is, as a method for taking out the work 30 in the next process, a method by tray inversion, a method by vacuum suction, or the like can be considered. If d1 ≧ 2H, in the case of tray reversal, when the work 30 is transferred from the second tray 22 to another tray by tray reversal, the work 30 may be reversed or rotated 90 °. is there. In the method using vacuum suction, after the workpiece 30 is vacuum-sucked, the distance that must be moved in the vertical direction before moving in the horizontal direction is increased, and the time required for taking out and moving the workpiece 30 is increased. is there.

(D) The planar shape of the first recess 28 and the planar shape of the work placement surface 34 are preferably “I” shapes in which the width of the central portion is smaller than the widths of both end portions. In general, when the planar shape of the recess is, for example, a “rectangular” shape, a certain amount of R shape is formed at the corner of the recess. In this case, the corners of the work 30 run over the corners of the first recesses 28 of the first tray 16 and the corners of the second recesses 32 of the second tray 22 to form the first recesses 28 and the second recesses 32. There is a possibility that such a problem may occur that it does not fit or the corners of the work 30 are missing on the wall surface of the first tray 16 or the second tray 22. Since the planar shape of the first concave portion 28 and the planar shape of the workpiece placement surface 34 are “I” shapes, the corner portions of the first concave portion 28 and the second concave portion 32 can be made to have no R shape. Such a problem can be prevented. The same applies to various modifications shown below.

  Next, a modified example of the tray jig 10 according to the present embodiment will be described with reference to FIGS. 6A to 13.

  As in the tray jig 10a according to the first modification shown in FIGS. 6A to 6C, the peripheral edge facing the first inner wall surface 32a that determines the outer end of the workpiece placement surface 34 among the peripheral edge of the second opening 20. A tapered surface 36 may be formed on the part. 6A to 6C are shown corresponding to the tray jig 10 (FIGS. 2A to 2C) according to the above-described embodiment.

  In this case, when the workpiece 30 is tilted toward the bottom 32 b of the second recess 32, the workpiece 30 is guided toward the inclination of the tapered surface 36 and moves toward the first inner wall surface 32 a of the second recess 32. Therefore, as shown in FIG. 6C, the workpiece 30 can be positioned in a narrower range than the case of the present embodiment (see FIG. 2C). In other words, the bottom 32b of the second recess 32 can be set narrow.

  In the above-described embodiment, the first opening 14 of the first tray 16 is the opening of the first recess 28 formed in the first tray 16, but the tray according to the second modification shown in FIG. It is good also as opening of the through-hole 38 formed in the 1st tray 16 like the jig | tool 10b.

  In this case, it becomes possible to change the direction of the workpiece 30 by the following procedure, and the man-hours can be reduced.

(1) As shown in FIG. 7A, the first tray 16 is covered so that the main surface 12 of the first tray 16 overlaps the main surface 18 of the second tray 22.

(2) Insert the workpieces 30 into the through holes 38 of the first tray 16. At this time, the work 30 is placed on the work placement surface 34 of the second recess 32.

(3) As shown in FIG. 7B, the first tray 16 is removed facing upward. Then, by applying vibration to the second tray 22, the workpiece 30 is easily tilted toward the intended direction, that is, the bottom 32 b of the second recess 32, and in the example of FIG. 7B, the direction of the workpiece 30 is changed by 90 °. Accordingly, the surface 30a facing the first inner wall surface 32a of the second recess 32 of the work 30 faces upward.

  Of course, like the tray jig 10c according to the third modification shown in FIG. 8, the second tray 22 has the same tapered surface 36 as the tray jig 10a according to the first modification (see FIGS. 6A and 6B). You may use the 2nd tray provided with the 2nd recessed part 32 which has.

  In the tray jig 10b according to the second modification and the tray jig 10c according to the third modification, a tapered surface 40 may be provided at the upper edge of the through hole 38 of the first tray 16, respectively. In this case, for example, as shown in FIGS. 9A to 10B, the shape of the through hole 38 viewed from the upper surface (planar shape of the through hole 38) is the shape of the work mounting surface 34 viewed from the upper surface (of the work mounting surface 34. (Planar shape) may be substantially the same. As the planar shape of the through-hole 38 and the planar shape of the workpiece placement surface 34, it is preferable to have an “I” shape in which the width of the central portion is smaller than the width of both end portions as in the above-described embodiment. . Thereby, in addition to the effects described above, the workpiece 30 can be easily placed on the workpiece placement surface 34 through the through hole 38 while being gripped by a human hand or a robot hand.

  Further, as in the tray jig 10d according to the fourth modification shown in FIG. 11, a first air blowing hole 42a having an opening at a position near the first inner wall surface 32a of the workpiece placement surface 34, and the first inner A second air blowing hole 42b having an opening in the wall surface 32a and an air suction hole 44 having an opening in the bottom 32b of the second recess 32 may be provided. When removing the first tray 16 upward, air is blown through the first air blowing hole 42a and the second air blowing hole 42b, and the air is sucked through the air suction hole 44, thereby The rotation of the workpiece 30 is promoted, and the workpiece 30 is easily tilted toward the intended direction, that is, the bottom portion 32b of the second recess 32, and the surface 30a facing the first inner wall surface 32a of the second recess 32 of the workpiece 30. Will face upwards. In this case, since the work 30 can be forcibly rotated, the direction of the work 30 can be easily changed. Although FIG. 11 shows an example in which the first air blowing hole 42a and the second air blowing hole 42b are provided as the air blowing holes, only the first air blowing hole 42a may be provided. Or only the 2nd air blowing hole 42b is good.

  Moreover, you may make it provide the protrusion 46 in the workpiece | work mounting surface 34 like the tray jig | tool 10e which concerns on the 5th modification shown in FIG. The positions and heights of the protrusions 46 are such that when the lower surface of the workpiece 30 falls toward the workpiece placement surface 34 or when the projections 46 are placed on the workpiece placement surface 34, the corners of the workpiece 30 are positioned on the workpiece placement surface 34. It is preferable that the lower surface of the work 30 is set so as to contact the protrusion 46 before colliding with or before contacting. As a result, inconveniences such as missing corners of the work 30 can be avoided.

  Moreover, the surface 48 where the corner | angular part of the 2nd level | step difference d2 which determines the inner end of the workpiece | work mounting surface 34 was chamfered like the tray jig | tool 10f which concerns on the 6th modification shown in FIG. As shown in FIG. 13, the chamfered surface 48 may be a flat surface (C surface) or an R surface (curved surface) although not shown. Also in this case, inconveniences such as part of the work 30 being missing can be avoided.

  It should be noted that the tray jig according to the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.
