  The press-fitting servo 9 pushes out the jig 8b and press-fits the part W1b attached to the jig 8b into the assembly target part W2. Similarly, after the drive shaft 4b rotates, the jigs 8a, 8c, and 8d are moved to the vicinity of the press-fitting servo 9, and then the press-fitting servo 9 pushes out the jigs 8a, 8c, and 8d, and the parts Each of W1a, W1c, and W1d is press-fitted into the assembly target component W2. For this press-fitting, the assembly target component W2 may be brought into contact with, approached or separated from each of the jigs 8a, 8b, 8c, and 8d as necessary.

(Example of operation)
Next, an example of the operation in which the rotational power unit 2 rotates the drive shaft 2b will be described with reference to FIGS. In FIG. 3 and FIG. 4, the table bodies 3a and 4a are drawn so as to be separated from each other on the xy plane for easy understanding, but actually, as shown in FIG. Note that it is in a position that appears to overlap. 3 and 4 are diagrams illustrating operations of main parts of the assembling apparatus according to the first embodiment.

  As shown in FIG. 3, the table main body 3a of the component supply table 3 has the drive shaft 3b so that the component holding portions 5a, 5b, 5c, and 5d are positioned in the component supply magazines 6a, 6b, 6c, and 6d, respectively. There may be a predetermined angle as the center.

  As shown in FIGS. 2 and 4, the rotary power unit 2 rotates the drive shaft 2b, thereby rotating the table body 3a of the component supply table 3 by 45 ° clockwise around the drive shaft 3b. Then, the table body 4a of the jig setup replacement table 4 rotates 45 ° counterclockwise around the drive shaft 4b. As a result, the jig 8d and the component holding unit 5d approach the component supply unit 7 (see FIG. 1). The jig 8d, the component holding unit 5d, and the component supply unit 7 may be arranged on the same virtual axis (here, the axis Z1 along the Z axis).

  Further, by rotating the table main body 3a of the component supply table 3 clockwise around the drive shaft 2b, the jig 8c and the component holding portion 5c are positioned in the vicinity of the component supply portion 7 (see FIG. 1). Further, if such rotation continues, a pair of jig 8b and component holding part 5b and a pair of jig 8a and component holding part 5a are located in the vicinity of component supply part 7 in this order, and again The jig 8d and the component holding unit 5d are located in the vicinity of the component supply unit 7.

(Parts supply method)
Next, an example of a component supply method using the assembly apparatus 10 will be described with reference to FIGS. In the example of the component supply method described below, the components W1b and W1d are alternately and continuously supplied. 5-7 is a figure which shows one step of the assembly method.

  The component W1d and the jig 8d are rotationally moved in the vicinity of the component supply unit 7 (setup position moving step ST1). Specifically, by driving the spur gear 2c of the rotational power unit 2 and rotating the table main bodies 3a and 4a by 180 ° in synchronization, the virtual axis that passes the component W1d and the jig 8d through the component supply unit 7 is obtained. (Here, the axis along the Z-axis).

  Subsequently, as shown in FIG. 5, the component W1d is attached to the jig 8d (setup step ST2). Specifically, the component supply unit 7 pushes up the component W1d, moves it upward from the component holding unit 5d, and attaches it by pressing it against a predetermined position of the jig 8d, for example, a protrusion.

  Subsequently, as shown in FIG. 6, the jig 8d is moved to the assembly target part W2 while the part W1d is attached to the jig 8d (press-fit position moving step ST3). More specifically, the spur gear 2c of the rotary power unit 2 (see FIG. 2) is driven by the drive described above, and the table main bodies 3a and 4a are rotated in synchronization by 180 °, thereby the parts W1d and the jig 8d. Approach. Specifically, the part W1d and the jig 8d are positioned on the imaginary axis (here, the axis Z1 along the Z axis) passing through the part to be assembled W2 in the vicinity of the part to be assembled W2 and cured with the part W1b. The tool 8b is positioned on a virtual axis passing through the component supply unit 7.

  Finally, as shown in FIG. 7, the component W1d is press-fitted into the assembly target component W2 (press-fitting step ST4). While performing this press fitting, the component W1b is attached to the jig 8b. Specifically, as in the setup step ST2, the component supply unit 7 pushes up the component W1b, moves it upward from the component holding unit 5b, and attaches it by pressing it against a predetermined position of the jig 8b, for example, a protrusion. .

  As described above, by sequentially repeating the setup position moving step ST1 to the press-fitting step ST4, the parts W1b and W1d can be alternately press-fitted into the assembly target part W2, and an assembly can be formed. In such a case, different parts W1b and W1d can be attached to the jigs 8b and 8d without using the hand of the operator. Therefore, the assembly can be assembled by attaching the components W1b and W1d to the jigs 8b and 8d corresponding to the components W1b and W1d, respectively, and automatically supplying the components W1b and W1d. In addition, it is possible to press-fit the parts W1b and W1d alternately into the assembly target part W2 to form a large number of assemblies.

(One variation of assembly device)
Next, with reference to FIGS. 8 and 9, an assembly apparatus 20 which is a modification of the assembly apparatus 10 (see FIG. 1) will be described. FIG. 8 is a perspective view showing a modification of the assembling apparatus according to the first embodiment. FIG. 9 is a side view showing a modification of the assembling apparatus according to the first embodiment. The assembling apparatus 20 has the same configuration as the assembling apparatus 10 except that two spur power units 23d and 24d are provided without requiring a spur gear. Each configuration of the assembly device 20 is numbered so as to correspond to the configuration of the same assembly device 10.

  As shown in FIGS. 8 and 9, the assembling apparatus 20 includes a component supply table 23 and a jig setup replacement table 24.

  The component supply table 23 includes a table body 23a, a drive shaft 23b, and a rotational power unit 23d. The rotational power unit 23d rotates the table body 23a around the drive shaft 23b.

  The jig setup replacement table 24 includes a table main body 24a, a drive shaft 24b, and a rotational power unit 24d. The rotational power unit 24d rotates the table body 24a around the drive shaft 24b.

  The rotational power unit 23d and the rotational power unit 24d can drive the table body 23a and the table body 24a to rotate independently. As a result, a predetermined part among a plurality of parts W21 (not shown) can be selected and moved from the inside of the part supply magazine 26 to the part holding unit 25 so as to cut out the selected part. Further, among the plural types of parts W21 (not shown), different types of predetermined parts are selected, attached to the corresponding jigs, press-fitted into the assembly target part W22, and these are repeated to be of different types. Assemblies can be produced. That is, mixed flow production in which a plurality of types of assemblies are produced using one assembly apparatus 20 can be performed.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, in the component supply method using the assembly apparatus 10 described above, the components W1b and W1d are sequentially supplied in sequence, but the components W1a, W1b, W1c, and W1d may be continuously supplied in this order.
