By the way, in the automated line of electronic equipment, although the shape is slightly different, parts having almost the same shape as a whole may be conveyed by the same conveying belt conveyor. Also, there may be several types of such shape-like parts. When transporting several types of parts with slightly different shapes on the same conveyor belt conveyor with approximately the same posture, if the posture of those components is controlled by the parts feeder, the parts feeder corresponding to each type Is needed. However, the arrangement of parts feeders corresponding to the types of parts requires a place, and the parts feeder itself has a complicated structure and is expensive, leading to high costs.

  Hereinafter, an embodiment of a component attitude control device of the present invention will be described with reference to the drawings. As shown in FIG. 1, the component posture control device of this embodiment controls the posture of a component W that is placed on and conveyed by the conveyor belt conveyor 1 during the conveyance. The conveyor belt conveyor 1 is configured by disposing rollers 2 at both left and right ends in FIG. 1 and winding a thin plate-like flexible belt 3 around these rollers 2. Any one of these rollers 2 is rotationally driven by a motor (not shown), and the component W placed on the upper surface of the belt 3 is conveyed from right to left in FIG. In addition, the belt 3 has some bending similarly to the existing conveyor belt conveyor 1, and further allows some bending. Further, like the existing conveyor belt conveyor, in order to prevent the belt 3 from meandering, for example, a guide in which the central portion in the width direction of the belt 3 is slightly raised may be provided.

  In the conveying direction of the component W by the conveying belt conveyor 1, a component supplying device 4 that supplies the upper surface of the belt 3 is arranged on the uppermost stream side of the conveying belt conveyor 1 so that the components W do not overlap. However, the component supply device 4 is not a so-called parts feeder that cuts out while controlling the posture of the component W. As shown in FIG. 2, an approach angle adjusting mechanism 5 that adjusts the approach angle of the part W to the posture changing mechanism, which will be described later, is provided above the conveyor belt conveyor 1 on the downstream side of the parts feeding direction of the parts supply device 4. Has been placed. An attitude changing mechanism 6 that changes the attitude of the component W being conveyed to a preset attitude is disposed above the conveyor belt conveyor 1 on the downstream side in the component conveying direction of the approach angle adjusting mechanism 5. A camera 7 that images the posture of the component W to be conveyed is disposed above the conveying belt conveyor 1 on the downstream side in the component conveying direction of the posture changing mechanism 6, and further the conveying belt conveyor 1 on the downstream side in the component conveying direction. A component removal device (manipulator) 8 that removes a component W that is not in a preset posture from among the component postures captured by the camera 7 is disposed above. And the conveyance apparatus which is not illustrated to the following process is arrange | positioned in the component conveyance direction most downstream side of the conveyor belt conveyor 1. FIG.

  A component W that is transported and controlled in posture in this embodiment will be described with reference to FIGS. The component W in this embodiment has a rectangular plate-like projection P projecting in the thickness direction from one end in the longitudinal direction of the rectangular (rectangular) plate-like base B, and is formed in an L shape as a whole. ing. Further, the base B is wider than the protrusion P. In this embodiment, the posture of the component W is controlled to the state shown in FIG. 3 for the next process. The component W tends to have a more stable posture of FIG. 4 due to its shape and size, but this is controlled to the posture of FIG. 3 while being conveyed by the conveying belt conveyor 1. 3 is also referred to as a normal posture, and the component posture in FIG. 4 is also referred to as a reverse posture. In the drawing, the shape of the component W is one type, but actually, three to four types of components W having slightly different shapes are conveyed by the conveyor belt conveyor 1.

  The posture changing mechanism 6 shown in FIG. 6 is held by the gap adjusting mechanism 9 shown in FIG. In the posture changing mechanism 6, a plurality of, specifically eight, plates 11 are projected from the rotating shaft 10 in the radial direction at equal intervals, and a large number of brushes are also radially spaced from the rotating shaft 10 between the plates 11. 12 is projected. The plate 11 is a resin plate member continuous in the direction perpendicular to the paper surface of FIG. 6, and the brush 12 is made of resin. Therefore, both the plate 11 and the brush 12 are flexible and elastic. Further, the radially outer end portion of the brush 12 is equivalent to the radially outer end portion of the plate 11 or is located on the radially inner side. The plate 11 abuts against the protruding end of the protrusion P of the component W to invert the component W, thereby changing the component posture. The brush 12 is for preventing the component W to be reversed from being caught in the gap between the plates 11. Note that the posture changing mechanism 6, that is, the plate 11 and the brush 12 rotates in the direction opposite to the conveying direction of the component W at the lower end portion on the conveying belt conveyor 1 side. Further, the outer diameter portion of the posture changing mechanism 6, that is, the radial front end portion of the plate 11 and the brush 12 rotates at a speed faster than the conveying speed of the component W by the conveying belt conveyor 1.

  The gap adjusting mechanism 9 is a bearing block 13 that rotatably supports the rotation shaft 10 of the posture changing mechanism 6 in the width direction of the belt 3 of the conveyor belt conveyor 1 and a movement that moves the bearing block 13 in the vertical direction. And a mechanism 14. As the moving mechanism 14, for example, a vertically vertical guide 16 fixed to the bearing block 13 and slidably inserted into the gantry 15, and the bearing block 13 is supported from below and screwed into a female screw of the gantry 15. And a screw member 17 that moves the bearing block 13 in the vertical vertical direction by the thrust of the screw. Therefore, when the screw member 17 of the moving mechanism 14 is rotated, the bearing block 13 is moved in the vertical direction by the thrust of the screw while being guided by the guide 16. As a result, the gap between the lower end of the posture changing mechanism 6 on the conveyor belt conveyor 1 side, particularly the lower end of the plate 11, and the upper surface of the conveyor belt conveyor 1, particularly the belt 3 is adjusted.

  When the gap between the lower end portion of the plate 11 and the upper surface of the belt 3 is adjusted in this way, the contact state of the plate 11 with the component W placed on the upper surface of the belt 3 as shown in FIGS. Can be adjusted. 7, the distance (height) from the upper surface of the belt 3 to the upper end of the protrusion P is the distance from the upper surface of the belt 3 to the top of the component W in the normal posture shown in FIG. 8. A little longer (a little higher) than (height). Further, in the component W in the normal posture, the protruding end portion of the base B and the protruding end portion of the protruding portion P are in contact with the upper surface of the belt 3, and the contact area tends to be large because the contact area is small. When the plate 11 presses the component W in the direction opposite to the conveying direction, the belt 3 is not easily displaced, and when the plate 11 presses the component W downward, the belt 3 is easily bent downward. On the other hand, in the component W in the reverse posture, the plate surface of the base B is in contact with the upper surface of the belt 3 and the contact area is large, so that the contact stress is small, and the belt even if the plate 11 presses the component W downward. 3 does not bend down so much, and when the plate 11 pushes the component W in the direction opposite to the conveying direction, the component W is displaced or flipped. Therefore, by adjusting the gap between the lower end of the posture changing mechanism 6 on the conveyor belt conveyor 1 side and the conveyor belt conveyor 1, the component W in the opposite posture can be reversed to the normal posture, and the normal posture can be reversed. It is possible to maintain the posture of the component W at the position.

  When the rotating plate 11 is brought into contact with the projecting portion P of the component W and the component W in the reverse posture is reversed to the normal posture, the approach angle of the component W to the posture reversal mechanism, that is, the conveyance, as will be described later. The direction on the belt conveyor 1 is important. Therefore, an approach angle adjusting mechanism 5 that adjusts the approach angle of the component W is disposed upstream of the posture changing mechanism 6 in the component transport direction. The approach angle adjusting mechanism 5 includes a guide plate 18 disposed above the belt 3 of the conveyor belt conveyor 1, for example. The guide plate 18 is a rectangular plate member that is long in the component conveyance direction, for example, and has a contact surface 19 with which the component W contacts. In this embodiment, as shown in FIG. 2, the outer guide plate 18 having both the outer side in the belt width direction on the outer side in the belt width direction and the outer side spreading in the belt width direction on the outer side and the outer side in the belt width direction on the inner side in the belt width direction. An inner guide plate 18 that is disposed slightly upstream from the guide plate 18 in the component conveying direction, has a central portion in the belt width direction that is joined toward the upstream in the component conveying direction, and a downstream side in the component conveying direction that extends outward in the belt width direction. Composed. The inclination angle of the contact surface 19 of each guide plate 18 with respect to the component conveying direction is set in advance. As a result, the approach angle of the base portion B of the part W with respect to the rotational axis of the posture changing mechanism 6 into the posture changing mechanism 6 in the longitudinal direction is 45 ° or −45 ° (135 ° or −135 °). It has been found that the approach angle of the part W to the posture changing mechanism 6 may be an approach angle in the vicinity thereof, even if it is not strictly ± 45 ° or ± 135 °.

  In this embodiment, as shown in FIG. 9, each guide plate 18 is set in advance so that the upper end portion of the contact surface 19 with which the component W abuts is directed upstream in the component conveying direction. It is arranged obliquely at an inclination angle. For example, as shown in FIG. 10 a, when the contact surface 19 of the guide plate 18 is vertical, only the wide base B of the component W in the normal posture contacts the upper portion of the contact surface 19 of the guide plate 18. Touch. At this time, the protrusion P of the component W that is in contact with the upper surface of the belt 3 is pushed in the component conveyance direction, and the base B is in the direction opposite to the component conveyance direction by the reaction force from the upper part of the contact surface 19 of the guide plate 18. The part W is tilted by being pushed. The base B of the part W is eventually separated from the contact surface 19 of the guide plate 18, but as shown in FIG. 10b, one corner of the protruding end of the protrusion P is the upper portion of the contact surface 19 of the guide plate 18. The other corner is in contact with the upper surface of the belt 3. At this time, the other corner of the protrusion P of the component W is pushed in the component conveyance direction by the conveyor belt conveyor 1, and the one corner is a reaction force from the upper part of the contact surface 19 of the guide plate 18. Thus, the component W is rotated by being pushed in the direction opposite to the component conveying direction. The other corner of the projection P of the component W is eventually separated from the belt 3, but the guide plate 18 is in a state where the protruding end of the projection P of the component W is separated from the upper surface of the belt 3 as shown in FIG. The base B of the component W is in contact with the upper surface of the belt 3. At this time, the base B of the component W is pushed in the component conveying direction by the conveyor belt conveyor 1, and the protrusion P of the component W is opposite to the component conveying direction by the reaction force from the contact surface 19 of the guide plate 18. The component W is further rotated by being pushed. As a result, as shown in FIG. 10 d, the base B of the component W comes into surface contact with the upper surface of the belt 3, and at this time, the base B comes into contact with the lower portion of the contact surface 19 of the guide plate 18. In this state, that is, in the reverse posture, the component W is unlikely to generate a couple, so the component W does not rotate and the base B of the component W slides on the upper surface of the belt 3. In other words, if the contact surface 19 of the guide plate 18 is vertical, the component W that is normally required in the normal posture is reversed to the reverse posture. Therefore, the guide plate 18 is disposed obliquely at a preset inclination angle so that the upper end portion of the contact surface 19 of the guide plate 18 faces upstream in the component conveying direction. The inclination angle of the contact surface 19 of the guide plate 18 with respect to the conveyor belt conveyor 1 is such that the base B of the component W in the normal posture contacts the contact surface 19 of the guide plate 18 and the protrusion P of the component W is the belt. 3, the angle at which the component W does not rotate even if a couple is generated in the component W.

  In this way, the approach angle of the component W can be adjusted by the guide plate 18 which is the approach angle adjusting mechanism 5, but the component W in the reverse posture is changed to the normal posture by the posture changing mechanism 6. The approach angle of the part W that can be performed will be described. Here, as shown in FIG. 11, with reference to the axis of the rotating shaft 10 of the posture changing mechanism 6, the axis of rotation of the base B in the longitudinal direction from the protruding end of the base B of the component W toward the protruding portion P is used. It was examined whether or not the component W in the reverse posture can be changed to the normal posture by the posture changing mechanism 6 by changing the counterclockwise angle of.

  FIG. 11 is a plan view showing a state immediately before the component W is transported to the posture changing mechanism 6, where the protrusion P of the component W is upstream in the component transport direction and the protruding end of the base B is downstream in the component transport direction. The angle with respect to the axis of rotation of the base B in the longitudinal direction is + 90 °. FIG. 12 is a plan view showing a state of the component W immediately after the component W of FIG. 11 is conveyed to the posture changing mechanism 6. As is apparent from FIG. 12, when the angle of the base B with respect to the longitudinal axis of rotation is + 90 °, the posture changing mechanism 6 cannot reverse the component W in the reverse posture to the normal posture. This is presumably because the protruding end of the base B of the part W is conveyed to the posture changing mechanism 6 in advance, and the base B is pressed by the brush 12 at that time.

  FIG. 13 is a plan view showing a state immediately before the component W is transported to the posture changing mechanism 6, where the protruding end of the base B of the component W is upstream in the component transport direction and the protrusion P is downstream in the component transport direction. Therefore, the angle of the base B with respect to the rotation axis in the longitudinal direction is −90 °. FIG. 14 is a plan view showing a state of the component W immediately after the component W of FIG. 13 is conveyed to the posture changing mechanism 6. As is clear from FIG. 14, when the angle of the base B with respect to the longitudinal axis of the rotation axis is −90 °, the posture changing mechanism 6 cannot reverse the component W in the reverse posture to the normal posture. This is because the protrusion P of the component W is transported to the posture changing mechanism 6 in advance, and the protrusion P is pushed or repelled by the plate 11 in the direction opposite to the transport direction. Conceivable.

  FIG. 15 is a plan view showing a state immediately before the component W is conveyed to the posture changing mechanism 6, and since the base B of the component W is fed sideways to the posture changing mechanism 6, the rotation axis of the base B in the longitudinal direction The angle to is 0 °. FIG. 16 is a plan view showing a state of the component W immediately after the component W of FIG. 15 is conveyed to the posture changing mechanism 6. As can be seen from FIG. 16, when the angle of the base B with respect to the longitudinal axis of the rotation axis is 0 °, the posture changing mechanism 6 can reverse the component W in the reverse posture to a certain normal posture ( Those in which the protrusion P does not appear are normal postures). This is because the projection P of the component W is caught by the plate 11 and the entire component W is inverted, but it is considered that the projection does not reverse if the projection P is simply pushed in the direction opposite to the conveying direction by the plate 11. It is done.

  FIG. 17 is a plan view showing a state immediately before the component W is transported to the posture changing mechanism 6, where the protrusion P of the component W faces outward in the belt width direction on the upstream side in the component transport direction, and the protruding end of the base B Is directed inward in the belt width direction on the downstream side in the component conveying direction, and therefore the angle of the base B with respect to the longitudinal axis of rotation is + 45 °. FIG. 18 is a plan view showing a state of the component W immediately after the component W of FIG. 17 is conveyed to the posture changing mechanism 6. As is apparent from FIG. 18, when the angle of the base B with respect to the rotation axis in the longitudinal direction is + 45 °, the posture changing mechanism 6 cannot reverse the component W in the reverse posture to the normal posture. This is because the projecting end portion of the base B is first transported to the posture changing mechanism 6 and the base B is pressed by the brush 12, or the projecting portion P is flipped by the plate 11 in the direction opposite to the transport direction. This is probably because of this.

  FIG. 19 is a plan view showing a state immediately before the component W is conveyed to the posture changing mechanism 6, where the protrusion P of the component W is inward in the belt width direction on the upstream side of the component conveyance direction, and the protruding end of the base B Is directed outward in the belt width direction on the downstream side in the component conveying direction, and therefore, the angle of the base B with respect to the longitudinal axis of the longitudinal axis is + 135 °. FIG. 20 is a plan view showing a state of the component W immediately after the component W of FIG. 19 is conveyed to the posture changing mechanism 6. As can be seen from FIG. 20, when the angle of the base B with respect to the longitudinal axis of rotation is + 135 °, the posture changing mechanism 6 cannot reverse the component W in the reverse posture to the normal posture. This is because the projecting end of the base B is transported to the posture changing mechanism 6 in advance and the base B is pressed by the brush 12, or the projecting part P is flipped by the plate 11 in the direction opposite to the transport direction. This is probably because of this.

  FIG. 21 is a plan view showing a state immediately before the component W is conveyed to the posture changing mechanism 6, and the protruding end portion of the base B of the component W faces outward in the belt width direction on the upstream side in the component conveying direction. Is directed inward in the belt width direction on the downstream side in the parts conveying direction, and therefore the angle of the base B with respect to the longitudinal axis of the longitudinal axis is −135 °. FIG. 22 is a plan view showing a state of the component W immediately after the component W of FIG. 21 is conveyed to the posture changing mechanism 6. As is apparent from FIG. 22, when the angle of the base B with respect to the rotation axis in the longitudinal direction is −135 °, the posture changing mechanism 6 can reverse the component W in the reverse posture to the normal posture. This is considered to be because the protrusion P of the component W is caught by the plate 11 and the entire component W is inverted.

  FIG. 23 is a plan view showing a state immediately before the component W is conveyed to the posture changing mechanism 6, and the protruding end of the base B of the component W is inward in the belt width direction on the upstream side in the component conveying direction. Is directed outward in the belt width direction on the downstream side in the component conveying direction, and therefore the angle of the base B with respect to the longitudinal axis of the base B is −45 °. FIG. 24 is a plan view showing a state of the component W immediately after the component W of FIG. 23 is conveyed to the posture changing mechanism 6. As is apparent from FIG. 24, when the angle of the base B with respect to the rotation axis in the longitudinal direction is −45 °, the posture changing mechanism 6 can reverse the component W in the reverse posture to the normal posture. This is considered to be because the protrusion P of the component W is caught by the plate 11 and the entire component W is inverted.

  By arranging the guide plate 18 as the approach angle adjusting mechanism 5 as described above, in this embodiment, the approach angle of the base B of the part W to the posture changing mechanism 6 is set to ± 45 ° or ± 135 °. Can do. Among these, when the approach angle of the base part B of the part W to the posture changing mechanism 6 is −45 ° or −135 °, the component W in the reverse posture can be reversed to the normal posture. When the approach angle of the base part B of the part W to the posture changing mechanism 6 is + 45 ° or + 135 °, the part W in the reverse posture cannot be reversed to the normal posture. If the guide plate 18 is flipped in the direction opposite to the conveying direction, the approach angle of the base part B of the component W to the posture changing mechanism 6 may be −45 ° or −135 ° by the guide plate 18. The component W in the posture is reversed to the normal posture.

  Table 1 below shows that 285 parts W are not overlapped at a time, and the posture and direction are randomly introduced into the conveyor belt conveyor 1 and passed through the posture changing mechanism 6 through the entrance angle adjusting mechanism 5. This is a result of determining the posture of the component W that has passed through the posture changing mechanism 6 five times. As is apparent from the table, 99.2% of the parts W randomly input can be in the normal posture. In this embodiment, as described above, the component W that is not in the normal posture is removed from the conveyor belt conveyor 1 by the camera 7 and the component removing device 8, so that the posture of the component W is completely corrected by the posture changing device. It is not necessary to be in a posture. However, if the frequency of the component W in the normal posture is increased with a simple structure, the number of removal of the component W can be reduced by that amount, so that the work efficiency is improved.

  As described above, in the component attitude control device of this embodiment, the protrusion P is formed with respect to the base B, and the attitude of the component W that is carried on the conveyor belt conveyor 1 is conveyed. Control during transport. At that time, an attitude changing mechanism 6 disposed above the conveyor belt conveyor 1 and having a lower end on the conveyor belt conveyor 1 side rotating in a direction opposite to the conveying direction of the parts W by the conveyor belt conveyor 1, and an attitude changing mechanism A gap adjusting mechanism 9 for adjusting a gap between the lower end of the conveyor belt conveyor 1 on the side 6 and the conveyor belt conveyor 1 is disposed. In the posture changing mechanism 6, the plate 11 and the brush 12 protrude in the radial direction of the rotating shaft 10, and the plate 11 contacts the protruding portion P of the component W to change the posture. For this reason, it is possible to hook and reverse the component W in the reverse posture in which the protrusion P is facing upward to be in the normal posture. Accordingly, it is possible to control the parts W of similar shapes having slightly different shapes to approximately the same posture with a simple structure.

Further, when the base B is a square plate and the protrusion P is a part W protruding from the square plate-like base B in the plate thickness direction, the approach angle adjusting mechanism 5 is transferred from the attitude changing mechanism 6 to a conveyor belt conveyor. 1 on the upstream side in the conveying direction of the part W. In this approach angle adjusting mechanism 5, the contact surface 19 with which the component W conveyed by the conveyor belt conveyor 1 abuts is inclined at a preset angle with respect to the conveying direction of the component W by the conveyor belt conveyor 1. Yes. Therefore, the approach angle to the posture changing mechanism 6 of the reversely oriented component W in which the rectangular plate-like base B is in contact with the conveyor belt conveyor 1 can be set to a preset angle. It is possible to control parts W of similar shapes having different shapes to approximately the same posture.
Further, in the approach angle adjusting mechanism 5, the contact surface 19 is inclined at a preset inclination angle with respect to the conveyance surface of the conveyance belt conveyor 1, that is, the upper surface of the belt 3. Thereby, it can prevent that the component W of the normal attitude | position in which the protrusion P is contacting the conveyor belt conveyor 1 becomes a reverse attitude | position.
