On the other hand, the chuck member 102 can be moved in the vertical direction and the front-rear direction by uniaxial loaders 105 and 106 each having a servo motor, and can be rotated in a vertical plane by a rotary cylinder 107. In addition, a chuck cylinder 108 is provided to drive the chuck member 102.

  The assembly parts 200 supplied in a row by the parts feeder 109 are sequentially transferred to the support base 101 of the assembly apparatus 100 at the position shown in FIG. 9B. Here, for the sake of simplicity, the assembly component 200 has a block-like schematic shape, and has a groove for attaching to the assembly target component 300 (injector) on the upper surface 201 side in the conveying posture. From this state, the orientation is changed and the posture is changed so that the groove portion faces the part 300 to be assembled. Therefore, first, the support base 101 and the chuck member 102 are moved by the upper and lower cylinders 103, the rotary cylinder 104, and the uniaxial loaders 105 and 106 so that the positional relationship shown in FIG. Then, the assembly component 200 on the support base 101 is held by the chuck member 102 using the chuck cylinder 108.

  Thereafter, the support base 101 is lowered by the upper and lower cylinders 103 and rotated 90 degrees in the vertical direction by the rotary cylinder 107 while the assembly component 200 is held by the chuck member 102. Further, when the uniaxial loaders 105 and 106 move to a position corresponding to the part to be assembled 300, the posture of the assembled part 200 is changed so that the upper surface 201 at the time of conveyance is the front as shown in FIG. 9B. In this state, it is possible to face the assembly target component 300.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall configuration diagram of a high-speed assembly apparatus 1 including a component attitude conversion device to which the component attitude conversion method of the present invention is applied. FIG. 2 shows an example of a component to which the present invention is applied. FIGS. 2A and 2B are schematic configuration diagrams showing the overall shape of the retainer R, which is an assembly component, and the state of assembly to the injector I, which is an assembly component. As shown in FIGS. 2A and 2B, the retainer R includes a substantially U-shaped attachment portion R1 that is fitted to the upper outer periphery of the injector I, and a support portion R2 that is erected from the center portion of the U-shape. Consists of. The support portion R2 extends along the upper side surface of the injector I, and the tip end side is branched into three. The injector I is supported by the retainer R, with the lower half portion inserted through a mounting hole of a cylinder head (not shown) and the upper half portion to which the retainer R is mounted projecting from the mounting hole. The support portion R2 of the retainer R is configured so as to follow the shape of the attachment portion at this time, and here, the both ends branched into three are bent to the attachment portion R1 side.

  In FIG. 1, the high-speed assembly apparatus 1 is provided with a receiving portion 11 that receives assembly parts (retainers R) conveyed in a row from a conveyance path (not shown) in a first posture at a corner portion on a rectangular table T. At the diagonal position of the receiving unit 11, there is a posture conversion unit 12 that changes the first posture to the second posture in order to assemble to the part to be assembled (injector I). The receiving portion 11 and the posture changing portion 12 are the first position and the second position in the present invention, and the 1/4 arc-shaped transfer path 2 through which the retainer R is transferred between the first and second positions. (Indicated by the alternate long and short dash line in the figure). On the transfer path 2, a movable stopper 5, which is a stopper member, is installed at a position immediately before the posture conversion unit 12.

  The retainer R is transferred by a transfer unit 3 as transfer means. The transfer unit 3 includes an arm member 31 disposed on the table T, and a hooking member 4 that is fixed to the tip of the arm member 31. The arm member 31 is supported by an up-and-down drive actuator 32 and a rotary drive actuator 33 arranged on the side of the table T so that the arm member 31 can rotate and move up and down around the end opposite to the hooking member 4. Has been. The hooking member 4 has a rectangular convex portion 41 projecting from the lower surface of the distal end portion of the arm member 31 and an abutting portion 42 projecting to the side of the rectangular convex portion 41.

  As shown in FIGS. 3A to 3C, the abutting portion 42 of the hooking member 4 is formed from a pair of rod-like bodies that protrude from the lower end portion on the back side to the left and right sides in the transfer direction of the rectangular convex portion 41. Become. The hooking member 4 is generally T-shaped as a whole by the contact portion 42 and the rectangular convex portion 41. In FIG. 3A, the retainer R is transported to the receiving unit 11 in the transport posture which is the first posture. In this transport posture, the retainer R is in a laid-down state in which both ends of the U-shape of the attachment portion R1 are erected and the support portion R2 is in contact with the upper surface of the table T. The retainer R is in a stable posture in which the sideways posture is less likely to fall than the assembly posture (see FIG. 2A), which is the second posture. Can be suppressed. At this time, a substantially T-shaped groove portion R3 for inserting the hooking member 4 is formed between both ends of the U-shape of the attachment portion R1 and between the bending portion of the attachment portion R1 and the support portion R2. The

  In the receiving part 11, the retainer R is mounted so that the attachment part R1 is positioned on the transfer path 2 side and is on the front surface in the transfer direction. On the upper side of the retainer R, the hooking member 4 is disposed so as to face. As shown in FIGS. 3B and 3C, when the hook member 4 is lowered together with the arm member 31 by the vertical drive actuator 32 in FIG. 1, the hook member 4 supports the mounting portion R1. It is inserted through the groove portion R3 between the portions R2. And the rectangular convex part 41 of the hooking member 4 is positioned and held between the both ends of the U-shape of the mounting part R1, and the pair of contact parts 42 of the hooking member 4 are located on the back side of the mounting part R1, It abuts on both ends of the U-shape. At this time, the contact position of the contact portion 42 is set to the relatively upper end side on the back surface of the mounting portion R1, so that the posture can be easily changed, and the posture R can be easily separated from the retainer R.

  When the arm member 31 is pivoted together with the hooking member 4 by the rotation driving actuator 33 in FIG. 1, the rectangular convex portion 41 and the contact portion 42 of the hooking member 4 are pushed out to the transfer path 2 while guiding the retainer R, The retainer R moves in an arc shape on the transfer path 2 (indicated by an arrow in the figure). Here, the end side of the transfer path 2 is a posture conversion unit 12, and a rectangular plate-shaped movable stopper 5 is provided immediately before the end of the transfer path 2. The movable stopper 5 protrudes upward from the upper surface of the table T, and is pressed against the front surface of the central portion of the U-shape of the mounting portion R1 which is the front lower end portion of the retainer R to be transferred. At this time, since the arm member 31 continues to turn, the retainer R reverses with the lower end portion of the attachment portion R1 contacting the movable stopper 5 as a fulcrum, and the support portion R2 rises.

  Accordingly, in the retainer R, the mounting portion R1 is tilted forward, and the surface located on the front surface side in the transfer direction becomes the lower surface side in contact with the upper surface of the table T, and the second posture (assembly posture) Become. At this time, the width of the movable stopper 5 is smaller than the U-shaped width of the attachment portion R1 on the lower surface side, and is configured so as not to prevent the posture change of the retainer R. In addition, in the second posture, a restricting member 13 that contacts the lower front portion of the retainer R is disposed in front of the retainer R in the transfer direction so as to hold the second posture. In addition, the movable stopper 5 can take two positions: a contact position that protrudes from the upper surface of the table T and contacts the retainer R, and a storage position that is stored below the table T. As a result, after the posture is changed by the movable stopper 5, the movable stopper 5 can be moved to the storage position, and the retainer R can be easily transported to the assembly position.

  In FIG. 1, the rotation range of the arm member 31 is set so as to stop at a position rotated by, for example, about 100 degrees beyond the 1/4 circular arc (90 degrees) conveyance path 2 (in the figure, two points). (Indicated by a chain line). For this reason, the arm member 31 driven by the actuator 33 for rotational drive continues to rotate even after the retainer R contacts the movable stopper 5 and changes its posture, and the hook member 4 at the tip of the arm member 31 Remove from retainer R. In this manner, the retainer R can be transferred at high speed without being gripped by the transfer unit 3, and can be converted into a predetermined posture and can be made independent.

  On the upper side surface of the table T following the posture conversion unit 12, a transport unit 6 is provided for transporting the retainer R to the assembly position when the retainer R is in the second posture (assembly posture). The transport unit 6 includes an extruding member 61 that is an extruding means, facing the side of the mounting portion R1 of the retainer R. The pushing member 61 moves back and forth on the table T, pushes the retainer R from the side in the assembling direction (indicated by an arrow in FIG. 1), and can be conveyed to an assembling position (not shown) outside the table T. It has become. Therefore, the injector I which is a member to be assembled is arranged facing the push position of the retainer R, and, for example, another push member (not shown) is arranged on the back surface of the retainer R, so that the posture can be changed quickly. Can be assembled.

  FIG. 4 is a schematic diagram showing a series of process examples from the posture change of the conveyed retainer R to the assembly with the injector I using the high-speed assembly apparatus 1 having the above configuration. Next, a series of these steps using the component orientation conversion method of the present invention will be described based on the flowchart of FIG. As shown in step (1) of FIGS. 4 and 5, the retainer R that is a component is first pushed out in a line on the conveyance path 14 in the same conveyance posture (first posture) in the sideways state. Aligned and supplied to the attaching device 1. The assembling apparatus 1 separates only the head part of the retainer R and pushes it out to the receiving part 11 on the table T. Next, in the step (2), the arm member 31 of the transfer part 3 is lowered and separated. The hooking member 4 is inserted into the groove R3 of the retainer R from above. Here, for the sake of simplicity, the entire hooking member 4 is illustrated as a substantially rod-shaped body, and is brought into contact with the upper rear side of the attachment portion R1.

  The hooking member 4 is configured to be able to rotate and move on the arc-shaped transfer path 2 toward the posture converting unit 12 with the base end portion of the arm member 31 as the center (indicated by a black circle in FIG. 4). Therefore, as shown in the step (3) of FIGS. 4 and 5, the hooking member 4 is rotated at a high speed in the transfer direction indicated by the arrow, and the movable stopper is disposed in the rotating track (here, 90 ° rotation position). 5 is applied to the lowermost part of the front surface of the retainer R. Then, as shown in the step (4), the retainer R rises by rotating around the contact surface of the movable stopper 5 due to the momentum of high-speed rotation and the inertia force generated by the sudden stop due to the contact of the movable stopper 5.

  As a result, not only can the stable transport posture (first posture) be converted to the assembly posture (second posture), but also the orientation of the retainer R can be changed using rotation. Therefore, the posture can be changed to a posture corresponding to the injector I which is a part to be assembled at a high speed with a small number of operations without using a conveyance loader or the like having a gripping member. (5) After that, as shown in the process, the assembly can be completed only by pressing the retainer R into the injector I using the pushing arrow 15 while facing the injector I while maintaining this assembly posture. Therefore, according to the present invention, it is possible to continuously carry out the posture change and assembly of parts with a simple device configuration and at a higher speed than in the past.

  In the first embodiment, the case where the retainer R is assembled to the injector I has been described. However, the shapes of the mounting portion R1 and the support portion R2 of the retainer R may be different from those of the present embodiment. If the shape has a groove-like portion R3 or a hole-like portion into which 4 can be inserted, the posture can be changed in the same process. In the case where a hole-shaped portion is provided instead of the groove-shaped portion R3, the hooking member 4 may be inserted from the lateral direction instead of from above. The parts to which the present invention is applied are not limited to the retainer R and other specially shaped parts, but can be applied to various shaped parts.

  FIG. 6A shows an example of another part shape and a posture changing method as the second embodiment of the present invention. The component 7 of the present embodiment has a substantially L-shaped block shape, and, like the retainer R of the first embodiment, in the illustrated transport posture (first posture), the front surface 71 side is the mounting portion R1 and the lower surface 72 side. Is the support portion R2. A U groove 75 is formed in the center of the attachment portion R1. In this state, when the front surface 71 side is set as the transfer direction and the transfer device 2 is transferred to the posture conversion unit 12 from the rear surface 74 side of the attachment portion R1 when the transfer path 2 is transferred to the posture conversion unit 12. The hook member 4 is inserted, the rectangular convex portion 41 is inserted into the U groove 75 in the center of the attachment portion R1, and the pair of contact portions 42 of the hook member 4 are brought into contact with the upper end of the back surface 74 of the attachment portion R1. .

  Thereby, like the retainer R of the first embodiment, the retainer R guided and transferred by the hooking member 4 can be applied to the movable stopper 5 at a high speed, and can be rotated using the lower end portion 73 of the front surface 71 in the transfer direction as a fulcrum. . Then, when the front surface 71 falls forward and the lower surface 72 shown in the figure rises, it can be converted into an assembly posture (second posture). Thus, the component 7 has a groove-like part or a hole-like part between the attachment part R1 and the support part R2, and the transfer direction is regulated by the rectangular convex part 41 and the contact part 42 of the hooking member 4 If it contacts from the back side, is transferred to the movable stopper 5 and is formed to be rotatable, the posture can be changed by the same method.

  Similarly, as shown in the left diagram of FIG. 6B, the present invention can also be applied to a block-like component 7 having a U-shaped cross section. In the second embodiment of FIG. 6A, the component 7 has the same shape as that of the mounting portion R1 only on the front surface 71 side. Similarly, the hook member 4 is in contact with the back surface 74. By moving to the front surface 71 side, the movable stopper 5 can be pressed against the lower end 73 of the front surface 71 and rotated. At this time, as shown in the right diagram of FIG. 6B, if the width of the movable stopper 5 is narrower than the groove 75 in the central portion, the movable stopper 5 can be avoided and rotated forward.

  For the block-shaped part 7 having the same U-shaped cross section as that in FIG. 6B, as shown in FIG. 6C, a conveying posture (first posture) in which both U-shaped end faces are opposed to each other in the vertical direction. Good. In this case, the lower side of the U-shaped both end surfaces is the lower end portion 73 of the front surface 71 and can be transferred to the front surface 71 side with the hooking member 4 in contact with the upper back surface 74. The groove 75 can be rotated forward while avoiding the movable stopper 5.

  Thus, in order to avoid the movable stopper 5 during rotation, the component to which the present invention is applied desirably has a concave portion, for example, a groove-shaped portion or a hole-shaped portion, on the front surface of the component. However, as shown in FIG. 7A, the block-shaped component 8 may have a shape having a convex portion 83 on the side. Here, a pair of rod-shaped convex portions 83 are provided at the lower ends of both side surfaces near the front surface 82 of the block-shaped component 8, and a pair of movable stoppers 51 and 52 are arranged at positions facing these convex portions 83. To do. At this time, instead of the hooking member 4 composed of the rectangular convex portion 41 and the contact portion 42 used in the above embodiment, for example, a substantially U-shaped hooking member 4 having a shape adapted to the block-shaped component 8 is used. use. The hooking member 4 is inserted from the upper rear side of the block-shaped component 8 as shown in the figure, and the side surface of the component 8 is regulated at both U-shaped ends. In this manner, the hook member 4 is transferred to the front surface 81 side in contact with the upper end portion of the back surface 84 of the component 8, and the pair of movable stoppers 51 and 52 are pressed against the pair of convex portions 83. It can be rotated with this as a fulcrum. Then, the illustrated front surface 81 falls forward, and the illustrated lower surface 82 rises, whereby the posture can be changed.

  Further, as shown in FIG. 7B, if the front surface 81 of the block-shaped part 8 has a rectangular groove 85 having a minimum size corresponding to the shape of the movable stopper 5, the movable stopper 5 is not rotated during rotation. It can be avoided. As shown in FIG. 7C, a square pipe shape having a through hole 86 at the center of the block-shaped component 8 may be used. In either case, the movable member 5 is moved at a high speed to the front surface 81 side with the hook member 4 in contact with the upper end portion of the rear surface 84 of the component 8 and pressed against the movable stopper 5, so that the movable stopper 5 is used as a fulcrum. It is possible to rotate around 5.

  As shown in FIG. 8A, the present invention can also be applied to the posture conversion of the cylindrical block-shaped component 8. Here, a columnar movable stopper 53 facing the lower end portion 83 of the front surface 81 is arranged, and a pair of flat plate-like regulating members 54 that regulate the rising direction of the component 8 are arranged on both sides thereof. At this time, the hook member 4 is brought into contact with the upper end portion of the back surface 84, transferred to the front surface 81 side at a high speed, and pressed against the movable stopper 5, whereby the front surface 81 lower end portion 83 can be rotated as a fulcrum, and The direction can be regulated.

  The columnar movable stopper 53 can also be used for posture change of the square pipe-shaped component 8 as shown in FIG. As described above, when the rising direction can be regulated by using the component shape, the guide, or the like, it can be rotated without being received by the surface of the movable stopper 53. In addition, it is desirable that the shape be able to stand by before and after rotation, but there is no particular limitation as long as it can be prevented from falling by a guide or the like.

  As described above, according to the present invention, it is possible to easily change the postures of parts having various shapes, and it is possible to simplify processes such as assembly. As described above, as described above, if there is a hooked part such as a notch groove or a bend in the center, such as a notch groove or a bending process, the part can be easily transferred by the transfer unit 3, and the position of the center of gravity is relatively high. If it is in the position, the part is easily reversed, but it is possible to cope with any shape by changing the shape of the hooking member 4 and the contact position according to the part.
