  As shown in FIG. 2A, the outer frame 34 is disposed at both ends in the width direction of the flat plate 32 and at the lower end thereof when viewed from the front side (or a direction perpendicular to the surface 32A). However, the lower portion of the outer frame 34 at the other end in the width direction of the flat plate 32 has the surface 32A exposed, that is, notched. In addition, the pair of ribs 36 are arranged so as to extend linearly from the upper end of the surface 32A to a position before reaching the lower end. Note that the distance between the pair of ribs 36 is longer than the length of the spring 130.

  Here, the position at one end side and the lower end side in the width direction on the surface 32A of the table 30 (the position surrounded by the two-dot chain line P1 in FIG. 2A) is defined as the first position. The position on the other end side and the lower end side in the width direction on the front surface 32A (the position surrounded by the two-dot chain line P2 in FIG. 2A) is the second position. The first component 110 and the second component 120 are arranged at the first position P1 and the second position P2, respectively, when the assembly 100 is manufactured (see FIG. 4A). From another perspective, the first part 110 and the second part 120 come into contact with the surface 32A and the outer frame 34 of the base 30 at the first position P1 and the second position P2, respectively, during the manufacture of the assembly 100. , Table 30.

That is, in the present embodiment, the table 30 can arrange the spring 130 along the surface 32A. Here, "the spring 130 is arranged along the surface 32A" means "the axis of the spring 130 is arranged along the surface 32A".
<Pressing member>
The pushing member 40 has a function of pushing the second component 120 from the other end in the width direction and moving the second component 120 from the other end in the width direction to one end during the manufacture of the assembly 100 (FIG. 4D). 4E and 4F). The pushing member 40 includes a contact member 42 and a rod 44 as shown in FIGS. 2A and 2B. The contact member 42 has a rectangular shape when viewed from a direction orthogonal to the surface 32A of the table 32 in a state where the pressing member 40 configures the specific manufacturing apparatus 10, and is fixed to one end of the rod 44. The rod 44 is movably supported in the width direction by a guide (not shown) on the other end side in the width direction with respect to the base 30. The contact member 42 is movable from the lower end portion (the portion without the outer frame 34) at the other end in the width direction of the flat plate 32 to the first position P1 with the movement of the rod 44 (FIG. 4D, 4E and 4F). Note that the state where the contact member 42 is located in a portion where the outer frame 34 is not present is a state where the pressing member 40 is located at the standby position. With the above configuration, the pressing member 40 moves the rod 44 in the width direction in a state where the second component 120 is in contact with the contact member 42, thereby moving the second component 120.
<Magnet>
The magnet 50 has a function of forming a magnetic field on the surface 32A of the table 30. The magnet 50 has a disk shape as shown in FIGS. 3A and 3B. Further, the magnet 50 of the present embodiment is a permanent magnet.

  The magnet 50 is supported by a guide (not shown). The magnet 50 is disposed on the back surface 32B side of the flat plate 32 and at a position overlapping the fourth position P4 when viewed from a direction perpendicular to the front surface 32A (see FIGS. 2A and 2B). The thickness direction of the magnet 50 extends along the direction from the lower end to the upper end of the flat plate 32 of the base 30 (see FIG. 2B). In other words, the magnet 50 has its axial direction along (the surface 32A of) the flat plate 32 (see FIG. 2B). As shown in FIG. 3A, the upper side of the magnet 50 in the thickness direction is an N pole, and the lower side is an S pole. In addition, as shown in FIG. 3A, the thickness of the magnet 50 is smaller than the outer diameter of the spring 130, for example. That is, the thickness of the magnet 50 of the present embodiment is equal to or less than the outer diameter of the spring 130.

  As shown in FIG. 3B, when viewed from the thickness direction (the direction along the surface 32A), the magnet 50 has a top 52 closest to the surface 32A of the flat plate 32, and is symmetrical with the top 52 interposed therebetween. And a portion 54 in which the distance from the surface 32A increases as the distance increases. Here, the portion 54 where the separation distance from the surface 32A increases is a portion of the outer periphery of the magnet 50 closer to the flat plate 32 than the axis O of the magnet 50 in FIG. 3B (the closer to the flat plate 32 than the broken line in the drawing). Portion), which means a portion other than the top portion 52.

  Here, the lines of magnetic force (two-dot chain lines in the figure) by the magnet 50 form a magnetic field on the surface 32A of the flat plate 32, as shown in FIG. 3A. In this case, when viewed from the radial direction of the magnet 50, the magnetic field formed by the magnet 50 is centered on an imaginary line (a line overlapping the broken line in the figure) extending in the radial direction of the magnet 50 and passing through the center in the thickness direction of the magnet 50. (See FIG. 3A). FIG. 3B illustrates a plurality of lines of equal magnetic force (two-dot chain lines in the figure) at the same magnetic force interval by the magnet 50. As shown in FIG. 3B, the distance between the lines of equal magnetic force increases as the distance from the outer periphery (the portion 54 where the distance from the top 52 and the surface 32A increases) increases in the radial direction. For this reason, when viewed from the thickness direction of the magnet 50, the magnetic flux density on the surface 32A formed by the magnet 50 becomes maximum at the position overlapping the top 52, and becomes symmetrical as the distance from the position overlapping the top 52 to both ends in the width direction increases. It is getting smaller. That is, at the fourth position P4 (see FIG. 2A), a magnetic field is formed in which the electric flux density at the center in the width direction is maximum and the electric flux density decreases symmetrically from the center to both ends in the width direction.

  Then, the magnet 50 forms the above-described magnetic field (see FIGS. 3A and 3B) at the fourth position P4 of the table 30, thereby setting the spring 130 in the determined posture (the posture along the fourth position P4). ), The spring 130 is positioned. Focusing on this point, in the specific manufacturing apparatus 10, a configuration including the table 30 (or a portion including at least the fourth position P4 in the table 30) and the magnet 50 (hereinafter, referred to as a positioning device 10A of the spring 130). 2A) has a function of positioning the spring 130 at a specific position (fourth position P4 in this embodiment) in a determined posture.

The above is the description of the specific manufacturing apparatus 10 of the present embodiment.
製造 Manufacturing method of assembly≫
Next, a method for manufacturing the assembly 100 using the specific manufacturing apparatus 10 of the present embodiment will be described with reference to the drawings. The method for manufacturing the assembly 100 includes a first step, a second step, a third step, and a fourth step described below. The manufacturing method of the assembly 100 is performed by an operator manually operating the specific manufacturing apparatus 10.
<First step>
The first step is a step of arranging the first component 110 and the second component 120 at predetermined positions on the surface 32A of the table 30. Specifically, as shown in FIG. 4A, the worker arranges the first component 110 at the first position P1 and the second component 120 at the second position P2. In this case, the operator sets one end of the main body 112 of the first component 110 to one end of the base 30 in the width direction. Further, the operator sets the other end of the main body 122 of the second component 120 to the other end of the base 30 in the width direction. Then, when the first component 110 and the second component 120 are arranged on the table 30 by the operator, the first process is completed.
<Second step>
The second step is a step of disposing the spring 130 at the fourth position P4. The second step is performed after the first step.

  Specifically, the operator carries the spring 130 to a position above the third position P3, and drops the spring 130 to the third position P3 (see FIG. 4B). As a result, the spring 130 moves between its pair of ribs 36 on the surface 32A due to its own weight (see FIG. 4C). When the spring 130 reaches the fourth position P4 (and its vicinity), the spring 130 moves along the fourth position P4 due to the magnetic field (see FIGS. 3A and 3B) formed on the fourth position P4 by the magnet 50. The posture is set to the fourth position P4.

When the spring 130 is positioned at the fourth position P4 and viewed from a direction perpendicular to the surface 32A, the axis of the spring 130 is aligned with the pin 116 of the first component 110 located at the first position P1. The axis overlaps with the axis of the pin 126 of the second component 120 located at the second position P2. When the specific manufacturing apparatus 10 is viewed from the width direction in a state where the spring 130 is positioned at the fourth position P4, the outer peripheral edges of the pins 116 and 126 are located within the inner peripheral edge of the spring 130. Thus, the second step is completed.
<Third step>
In the third step, using the pressing member 40, the second component 120 disposed at the second position P2 is moved from the other end in the width direction to one end, and the pin 126 of the second component 120 is moved to the fourth position. In this step, the spring 130 is inserted into the other end of the spring 130 positioned at P4. The third step is performed after the fourth step.

Specifically, the operator moves the pressing member 40 located at the standby position from the other end in the width direction to one end. As a result, as shown in FIG. 4E, the contact member 42 contacts the main body 122 of the second component 120, the second component 120 is moved to one end in the width direction, and the pin 126 is moved to the other end of the spring 130. Inserted. Thus, the third step is completed.
<Fourth step>
In the fourth step, the second component 120 in which the spring 130 is inserted is moved from the other end in the width direction to one end using the pressing member 40, and the pin 116 of the first component 110 is moved to one end of the spring 130. This is the step of inserting into The fourth step is performed following the third step.

  Specifically, the operator moves the pressing member 40 further from the other end in the width direction to one end. Accordingly, as shown in FIG. 4F, the second component 120 into which the spring 130 is inserted moves toward the first position P1, and the distal ends of the pair of hooks 124 of the second component 120 are moved to the first position. The hook is hooked on the tip of a pair of hooks 114 of the component 110. As a result, the assembly 100 is manufactured, and the fourth step is completed. When the fourth step ends, the method of manufacturing the assembly 100 according to the present embodiment ends. As described above, the fourth step is described separately from the third step. However, the third step and the fourth step may be regarded as the third step without being separated.

The above is the description of the method for manufacturing the assembly 100 of the present embodiment.

Then, the pin 126 of the second component 120 is inserted into the other end of the spring 130 held at the sixth position P6 by the moving device 60. Next, the operator operates the moving device 60 to separate the moving device 60 from the spring 130. Further, the worker moves the second component 120 by moving the pressing member 40 from the other end of the base 30B to the one end, and moves the second component 120 to the tip of the pair of hooks 114 of the first component 110 at the first position P1. The tips of the pair of hooks 124 of the second component 120 are hooked. The assembly 100 is manufactured by the above steps, and the manufacturing method of the assembly 100 of the first comparative embodiment ends.

  As described above, in the case of the first comparative example, the spring 130 is moved from the fifth position P5 to the sixth position P6 by using the moving device 60 (robot), and the spring 130 moved to the sixth position P6 is moved. It is necessary to hold in a state where the axial direction is along the longitudinal direction of the table 30B. In the case of the first comparative example, it is necessary to cancel the holding of the spring 130 by the moving device 60 at the timing when the pin 126 of the second component 120 is inserted into the other end of the spring 130 held at the sixth position P6. There is.

  On the other hand, in the case of the present embodiment, as described above, there are specific requirements (see FIGS. 3A and 3B). Therefore, in the case of the present embodiment, the spring 130 can be positioned in a determined posture (posture along the fourth position P4) without using the moving device 60 or the like as in the case of the first comparative embodiment. (See FIG. 4D). In other words, in the case of the present embodiment, for example, the spring 130 that approaches the fourth position P4 independently from a position other than the fourth position P1 can be easily determined (without using a mechanism such as the moving device 60). (Positions along the fourth position P4) (see FIGS. 4C and 4D).

Therefore, according to the positioning device 10 </ b> A of the spring 130 of the present embodiment, compared to the case where the moving device 60 grips the spring 130, moves the gripped spring 130, and positions the spring 130 while gripping it, it is simpler. With such a configuration (or in a short time), the spring 130 can be positioned in a determined posture. Along with this, according to the specific manufacturing apparatus 10 of the present embodiment, the moving device 60 grips the spring 130, moves the gripped spring 130, and positions the spring 130 with the spring 130 gripped. The assembly 100 can be manufactured with a simple configuration (or in a short time).
<Second operation and effect>
The second operation and effect is that the thickness of the magnet 50 is equal to or less than the outer diameter of the spring 130. The second operation and effect will be described by comparing the present embodiment with a second comparative embodiment.

  In the specific manufacturing apparatus 10C of the second comparative example, as shown in FIG. 6, the thickness of the magnet 50C is larger than the outer diameter of the spring 130. The second comparative example is the same as the present embodiment except for the above points. The fourth position P4 in the second comparative example is a position overlapping the magnet 50C on the surface 32A of the flat plate 32 when the flat plate 32 is viewed from the thickness direction. That is, the fourth position P4 of the second comparative example is wider than the fourth position P4 of the present embodiment.

  In the case of the second comparative example, the spring 130 dropped from the third position P3 is positioned at the fourth position P4 by the magnetic force of the magnet 50C. Specifically, the spring 130 is positioned in a state where its axial direction is along the width direction of the specific manufacturing apparatus 10C. The reason is that the shape of the magnet 50C of the second comparative embodiment viewed from the thickness direction is the same as the shape of the magnet 50 of the present embodiment viewed from the thickness direction. This is because the lines of equal magnetic force by the viewed magnet 50C show the same distribution as in the present embodiment (see FIG. 3B). As described above, since the second comparative example has the above-described specific requirements, it can be said that the second comparative example has the above-described first operation and effect. That is, the second comparative mode is a mode belonging to the technical scope of the present invention.

  By the way, in the case of the second comparative example, according to the test and research by the inventors of the present application, the spring 130 is positioned at any position in the thickness direction of the magnet 50C at the fourth position P4. Therefore, in the case of the second comparative example, the spring 130 can be made to extend along the axial direction in the width direction of the specific manufacturing apparatus 10C, but the position of the spring 130 in the thickness direction of the magnet 50C falls within the range of the width of the magnet 50C. Become. FIG. 6 illustrates a state where the spring 130 is positioned at the center position in the thickness direction of the magnet 50C at the fourth position P4.

  On the other hand, the thickness of the magnet 50 of the present embodiment is equal to or less than the outer diameter of the spring 130 (see FIG. 3A). That is, the width in the thickness direction of the magnet 50 at the fourth position P4 in the present embodiment is smaller than the width in the thickness direction of the magnet 50C at the fourth position P4 in the second comparative embodiment. Therefore, in the case of the present embodiment, the positioning is performed in a narrower range in the thickness direction of the magnet 50 than in the case of the second comparative embodiment. The reason is presumed as follows. That is, the magnetic lines of force (see FIG. 6) on the fourth position P4 in the second comparative embodiment (the portion on the surface 32A side in the thickness direction of the flat plate 32 at the fourth position P4) are the case of the present embodiment (see FIG. 3A). ), Along the surface 32A. Therefore, in the case of the second comparative example, it is inferred that the change in the direction of the magnetic field is gentle over the thickness direction of the magnet 50C at the fourth position P4 as compared with the case of the present embodiment. You.

  Therefore, according to the positioning device 10A of the spring 130 of the present embodiment, the spring 130 can be positioned in a narrower range in the thickness direction of the magnet 50 than when the thickness of the magnet 50C is larger than the outer diameter of the spring 130. it can. Along with this, according to the specific manufacturing apparatus 10 of the present embodiment, the pin 116 of the first component 110 and the pin 126 of the second component 120 have a larger thickness than the case where the thickness of the magnet 50C is larger than the outer diameter of the spring 130. On the other hand, both ends of the spring 130 can be easily inserted (or the insertion rate is high).

  As described above, the present invention has been described by taking a specific embodiment as an example, but the present invention is not limited to the above-described embodiment. For example, the technical form of the present invention includes the following embodiments.

  In the present embodiment, it has been described that the worker manually operates the specific manufacturing apparatus 10 to manufacture the assembly 100. However, by adding another element to the elements of the specific manufacturing apparatus 10 described in the present embodiment, the whole or a part may be automated and the assembly 100 may be manufactured. For example, a placement device (not shown) for placing the first component 110 at the first position P1, the second component 120 at the second position P2, a drop device (not shown) for dropping the spring 130 to the third position P3, a pushing member Specific manufacturing including some or all of a driving device (not shown) for moving the assembly 40, a moving device (not shown) for moving the completed assembly 100 at the first position P1, and a control device (not shown) for controlling these devices. It may be a device.

  In the present embodiment, the magnet 50 has been described as having a disk shape (see FIG. 3B). However, when viewed from the thickness direction of the magnet 50, the top 52 which is closest to the surface 32A of the flat plate 32 of the table 30 is symmetrical with respect to the top 52, and the distance from the surface 32A increases as the distance from the top 52 in the width direction increases. The shape of the magnet 50 may be different from that of the present embodiment as long as it has the portion 54, that is, if it has the above-mentioned specific requirements. For example, the shape may be a semi-disc like a magnet 50D shown in FIG. 7A. Further, it may be triangular like the magnet 50E shown in FIG. 7B.

  In the present embodiment, the surface 32A (the fourth position P4) of the table 30 on which the spring 130 is positioned has been described as a plane. However, at the fourth position P4, the spring 130 can be arranged in a direction perpendicular to the thickness direction of the magnet 50 (in the case of the present embodiment, in the radial direction of the magnet 50 and along the flat plate 32). The fourth position P4 on the surface 32A may not be a plane as long as the configuration satisfies the specific requirements of the above. For example, as shown in FIG. 8, a curved concave surface 32A1 may be used.

  In the present embodiment, the third position P3 is described as a position between the pair of ribs 36 in the width direction of the table 30 and a position on the upper end side. Also, the fourth position P4 has been described as a position between the pair of ribs 36 in the width direction of the table 30 and a position on the lower end side. However, the fourth position P4 may not be a position between the pair of ribs 36 in the width direction of the table 30. For example, as shown in FIG. 9, the fourth position P4 (that is, the position of the magnet 50) may be shifted in the width direction of the table 30 with respect to the third position P3. Even in this case, the spring 130 dropped from the third position P3 is positioned along the fourth position P4 by the magnetic force from the magnet 50.

  In the present embodiment, as described in FIG. 2B, the table 30 has been described as being supported by the support member 20 in a state where the back surface 32B is inclined downward. However, the table 30 may be supported in a horizontal state. Even in this case, if the spring 130 is moved closer to the fourth position P4 (for example, if the spring 130 is thrown from a position other than the fourth position P4), the spring 130 is positioned in a predetermined posture. can do. From another point of view, in the case of the present embodiment, the surface 32A constitutes an inclined surface (see FIG. 2B), and the third position P3 is located above the fourth position P4. Therefore, the spring 130 can be dropped from the third position P3 (that is, above the fourth position P4), and the spring 130 can be positioned at the fourth position P4.

  In the present embodiment, the description has been given assuming that the magnet 50 is a permanent magnet. However, the magnet 50 may be an electromagnet.

  In the present embodiment, it has been described that the second step is performed after the first step. However, as long as the first step and the second step are completed before the third step, the order of the first step and the second step does not matter. Further, the first step and the second step may be performed at the same timing.

  In the present embodiment, the first component 110 is provided with the pin 116, and the second component 120 is provided with the pin 126. The pins 116 and 126 are inserted into both ends of the spring 130 to constitute the assembly 100. (See FIG. 1). However, as shown in FIG. 10A, a round hole 116A is formed in the first component 110A in place of the pin 116 of the first component 110, and a round hole 126A is formed in the second component 120A in place of the pin 126 of the second component 120. Then, both ends of the spring 130 may be inserted into the round holes 116A and 126B to form the assembly 100A. Even in this case, the assembly 100A can be manufactured by the specific manufacturing apparatus 10 and the like of the present embodiment and the above-described modified example. In this case, the round holes 116A and 126B are examples of a concave portion and another concave portion, respectively. Note that an assembly may be configured by the first component 110, the second component 120A, and the spring 130, or by the first component 110A, the second component 120A, and the spring 130 (not shown).

  In the present embodiment, the assembly 100 has been described as including the second component 120. However, as a modified example of the assembly 100, as shown in FIG. 10B, an assembly 100 </ b> B including the first component 110 (the component 110 </ b> B in the drawing) without the pair of hooks 114 and the spring 130 may be used. . In this case, when the pin 116 is inserted into one end of the spring 130, the pin 116 is swaged by the spring 130. When manufacturing the assembly 100B, the other end of the spring 130 is pressed by the pressing member 40 to move the spring 130 with the component 110B arranged at the first position P1 and the spring 130 positioned at the fourth position P4. What should be done is. Note that the pin 116 of the component 110B may be a round hole 116A as in the case of FIG. 10A.

  In the present embodiment, an example of the magnetic body has been described as the spring 130. However, as long as it has a cylindrical or columnar shape and has magnetism, an example of the magnetic body may not be the spring 130. For example, a cylindrical pin (not shown), a cylindrical screw (bit screw, not shown), or any other magnetic component having a cylindrical or cylindrical shape may be used.

  In the present embodiment, it has been described that the magnet 50 is arranged at a predetermined position on the back surface 32B side of the table 30, and the magnet does not move. However, for example, the magnet 50 may be movable along the width direction of the table 30. In this way, for example, when manufacturing the component 100B as shown in FIG. 10B, if the magnet 50 is moved to one end in the width direction of the base 30 with the spring 130 positioned at the fourth position P4. With the movement of the magnet 50, the spring 130 can be moved to the first position P1 in the posture as it is (with the axial direction along the width direction of the base 30). As a result, for example, the component 100B can be manufactured without using the pressing member 40.
