As shown in FIG. 1, the control unit 60 mainly includes a CPU 61 and a memory 62. The CPU 61 executes operation control of the feeding unit 10 and the attachment unit 70 electrically connected by the signal line 69 at a predetermined timing in accordance with the program 62a stored in the memory 62.

<2. Configuration of mounting unit>
2 and 3 are a side perspective view and a front perspective view, respectively, showing an example of the configuration in the vicinity of the mounting unit 70. FIG. 4 is a back view showing an example of the configuration of the punch 71 of the mounting unit 70. As shown in FIG. 2, the attachment unit 70 mainly has a punch 71, a die 72, an elevating part 75, a punch support part 76, and a die case 78.

  The punch 71 is disposed above the feeding unit 10 and the die 72. As shown in FIGS. 3 and 4, the punch 71 mainly has a base 71a, a shaft 71b, and a suction part 71c.

  The base 71a and the shaft 71b are rod-shaped bodies extending in the Z-axis direction. As shown in FIG. 3, the size of the base portion 71a in the radial direction is larger than that of the shaft portion 71b. Further, as shown in FIG. 4, an adsorption portion 71 c made of, for example, a permanent magnet is provided at the tip of the base portion 71 a (end portion on the die 72 side).

  Here, a part of the thin part 5 is formed of a magnetic material, and the thin part 5 fed by the feeding unit 10 is attracted to the suction portion 71c of the punch 71 by a magnetic force. Thus, the punch 71 is used as a receiving unit that receives the thin part 5 from the feeding unit 10.

<3. Caulking operation of thin parts by mounting unit>
5 and 6 are a front perspective view and a front sectional view showing an example of the configuration of the thin part 5, respectively. 7 and 8 are diagrams for explaining the caulking operation of the plate material 9 by the mounting unit 70, respectively.

  As shown in FIGS. 5 and 6, the thin part 5 to be fed and attached mainly has a main body 6 and a protrusion 7. The main body 6 is a substantially disc body in which a recess 6d is formed near the center of the upper flat surface 6c. The protrusion 7 is a substantially cylindrical body that protrudes from the lower flat surface 6 a of the main body 6. Further, an annular groove 8 surrounding the protruding portion 7 is formed on the lower flat surface 6a.

  Here, as shown in FIG. 6, a protrusion corresponding to the recess 6 d of the main body 6 is formed at the tip 7 a of the protrusion 7. As a result, when the thin components 5 are stacked such that the main body 6 and the protrusion 7 face each other, the tip 7 a of the protrusion 7 is fitted into the recess 6 d of the main body 6. Therefore, as shown in FIG. 3 (and FIGS. 16 to 20 described later), a plurality of thin parts 5 can be stacked well.

  As shown in FIGS. 7 and 8, the caulking operation of the thin part 5 by the mounting unit 70 is performed as follows. First, as shown in FIG. 7, the thin component 5 fed from the feeding unit 10 is sucked by the suction portion 71 c provided at the tip of the shaft portion 71 b, and the plate material 9 is placed on the die 72.

As a result, the thin component 5 is driven into the plate material 9. Therefore, a hole is made in the plate material 9, and a part of the plate material 9 is introduced into the annular groove 8 of the thin component 5, whereby the thin component 5 is caulked to the plate material 9.

<4. Configuration of feeding unit>
Each of FIG. 9 and FIG. 10 is a side perspective view illustrating an example of the configuration of the feeding unit 10. FIG. 11 is a side perspective view illustrating an example of the configuration of the holding unit 20. FIG. 12 is a side perspective view illustrating an example of the configuration of the holding unit 20 and the adjustment unit 50. As shown in FIGS. 2, 3, 9, and 10, the feeding unit 10 mainly includes a holding unit 20, a drive unit 30, a supply unit 40, and an adjustment unit 50. .

  As shown in FIGS. 10 and 11, the holding unit 20 is a plate that extends in one direction (Y-axis direction: arrow direction AR1) (hereinafter referred to as “extension direction AR1”), and is supplied from the supply unit 40. The thin part 5 to be held is held. As shown in FIGS. 11 and 12, the holding portion 20 has a notch 21 and a terrace surface 22.

  The notch 21 is a cove-like recess formed at the tip 20a on the adjustment unit 50 side. The shape of the notch 21 (viewed from the supply unit 40 side) in plan view is U-shaped as shown in FIGS. 11 and 12.

  As shown in FIGS. 11 and 12, the terrace surface 22 is formed along with the notch 21 (that is, along the outline of the notch 21). As shown in FIGS. 11 and 12, the position of the terrace surface 22 in the Z-axis direction is lower than the upper surface 20 b of the holding unit 20. That is, the terrace surface 22 is one level lower than the upper surface 20b.

  The drive unit 30 moves the thin part 5 held by the holding unit 20 toward the mounting unit 70 by moving the holding unit 20 back and forth along the extending direction AR1. As shown in FIGS. 9 and 10, the drive unit 30 mainly includes a cylinder 31, a transmission unit 33, and a guide unit 35.

  The cylinder 31 is a driving force source for applying a driving force in the extending direction AR1 to the driving unit 30, and is configured by a so-called air cylinder. When the cylinder 31 is driven, the rod 32 of the cylinder 31 reciprocates in the extending direction AR1. Further, as shown in FIGS. 9 and 10, the tip of the rod 32 is connected to the transmission portion 33.

  As shown in FIGS. 9 and 10, the guide portion 35 is a frame body provided along the conveyance path TP of the thin part 5. The holding part 20 can slide on the inner peripheral surface of the guide part 35. Further, as shown in FIG. 9, the upper portion of the guide portion 35 can be closed by lid portions 36 and 37.

  Thereby, the moving direction of the holding part 20 is regulated in the extending direction AR1 by the guide part 35, and the thin part 5 held by the holding part 20 is adjusted as shown in FIG. 2, FIG. 9, and FIG. It is conveyed between the unit 50 and the supply unit 40.

  The transmission unit 33 is a member that transmits the driving force from the cylinder 31 to the holding unit 20. As shown in FIG. 10, a fitting portion 33 a that matches the shape of the fitting hole 25 of the holding portion 20 is formed at the tip of the transmission portion 33 on the holding portion 20 side. When the fitting portion 33a is fitted into the fitting hole 25, a gap is formed between the inner peripheral surface of the fitting hole 25 and the outer peripheral surface of the fitting portion 33a. That is, “play” is set between the fitting hole 25 and the fitting portion 33a.

  Thereby, the “deviation” between the advancing / retreating direction of the rod 32 by the cylinder 31 and the advancing / retreating direction of the holding part 20 by the guide part 35 can be absorbed. Therefore, the holding part 20 can be advanced and retracted smoothly.

  As shown in FIGS. 2 and 3, the supply unit 40 is provided above the holding unit 20 and the guide unit 35, and supplies the thin components 5 to the holding unit 20 one by one. As shown in FIGS. 2 and 3, the supply unit 40 mainly includes a storage unit 41 and an attachment unit 42.

  As shown in FIG. 3 (and FIGS. 16 to 20 described later), the storage unit 41 stores the thin components 5 arranged in a line. The attachment portion 42 is provided on the guide portion 35, and the storage portion 41 is detachable from the attachment portion 42. That is, the supply unit 40 stores the thin parts 5 arranged in a row in the replaceable storage unit 41.

  The thin part 5 supplied from the supply unit 40 is supported by the terrace surface 22 of the holding unit 20. Here, the level difference between the upper surface 20 b of the holding portion 20 and the terrace surface 22 is set to be approximately the same as the size of the main body 6 in the thin part 5 in the height direction (Z-axis direction). Therefore, the thin parts 5 are supplied from the supply unit 40 to the holding unit 20 one by one.

  The adjustment part 50 is a positioning element provided on the conveyance path TP of the thin part 5 as shown in FIGS. As shown in FIG. 12, the surface shape of the curved surface portion 51 of the adjusting portion 50 is a shape along the side surface of the main body portion 6 in the thin component 5.

  Thereby, when the thin component 5 is abutted against the curved surface portion 51 of the adjusting portion 50, the thin component 5 moves following the surface shape of the curved surface portion 51. Therefore, the arrangement of the thin parts 5 is finely adjusted while being supported by the holding unit 20.

  Here, when the thin part is a part having a through hole or a fastening hole (for example, a hexagonal hole), the positioning of the thin part with respect to the punch 71 of the mounting unit 70 is performed by providing a protrusion at the tip of the punch 71, for example. This can be realized by fitting this protrusion into the hole or the fastening hole.

  On the other hand, the main body portion 6 and the protruding portion 7 of the thin component 5 of the present embodiment are solid elements that do not have such through holes or fastening holes. In this case, the thin part 5 of the present embodiment cannot be positioned using the above-described protrusion. Therefore, the feeding unit 10 according to the present embodiment includes an adjusting unit 50 that is used as a positioning element with respect to the mounting unit 70 in order to feed the solid thin part 5 as a feeding target.

<5. Feeding operation of thin parts by feeding unit>
Each of FIGS. 13 to 15 is a plan view for explaining an example of the feeding operation of the thin component 5 by the feeding unit 10. Each of FIG. 16 to FIG. 20 is a side view for explaining an example of the feeding operation of the thin component 5 by the feeding unit 10. Here, a procedure for feeding the thin part 5 supplied from the supply unit 40 to the delivery position PT1 (first position) will be described with reference to FIGS.

  First, the control unit 60 operates the cylinder 31 of the drive unit 30 to move the terrace surface 22 of the holding unit 20 to the supply position PT2 (second position) that is directly below the supply port 40a of the supply unit 40. (See FIGS. 13 and 16).

  Here, as shown in FIGS. 16 to 20, in the storage unit 41 of the supply unit 40, each thin component 5 is stored so that the main body unit 6 faces upward and the protrusion 7 faces downward. That is, from the supply part 40, each thin component 5 stacked so that the main body part 6 and the protrusion part 7 face each other is supplied to the holding part 20 through the supply port 40a by its own weight. Then, as shown in FIG. 16, one thin component 5 is supplied to the holding unit 20 and supported by the terrace surface 22 of the holding unit 20.

  In this way, the control unit 60 causes the holding unit 20 to receive the single thin component 5 supplied from the supply unit 40 at the supply position PT2. As a result, the flange portion 6 b of the thin component 5 is supported by the terrace surface 22 of the holding portion 20.

  Next, the control unit 60 operates the cylinder 31 of the drive unit 30 to move the thin component 5 from the supply position PT2 to the adjustment unit 50 side while supporting the flange portion 6b of the thin component 5. (See FIGS. 14 and 17). Thereby, the thin component 5 is moved to the delivery position PT1 in a state where the supply port 40a of the supply unit 40 is closed on the upper surface 20b of the holding unit 20.

  Further, when the holding unit 20 is moved to the delivery position PT1, the thin component 5 is abutted against the adjusting unit 50. Thereby, the adjustment part 50 adjusts arrangement | positioning of the thin component 5 with respect to the punch 71 of the attachment unit 70 appropriately in the delivery position PT1 where the thin component 5 is delivered to the attachment unit 70. FIG. That is, the arrangement of the thin parts 5 is adjusted at the delivery position PT1.

  Further, the thin part 5 moved to the delivery position PT1 is adsorbed by the adsorbing portion 71c of the punch 71. That is, the punch 71 (receiving portion) of the mounting unit 70 receives the thin part 5 from the feeding unit 10 by attracting the thin part 5 at the delivery position PT1.

  Subsequently, the control unit 60 causes the mounting unit 70 to receive the thin part 5 at the delivery position PT1, and then operates the cylinder 31 of the drive unit 30. Thereby, the holding part 20 is moved to the supply part 40 side in the state in which the supply port 40a of the supply part 40 is closed by the upper surface 20b of the holding part 20.

  Subsequently, when the tip 20a of the holding portion 20 reaches the position PT3, the lowering operation of the punch 71 in the mounting unit 70 is started (see FIGS. 15 and 18). Thereby, when the front end 20a of the holding part 20 reaches the fourth position, the thin component 5 is caulked to the plate material 9 on the die 72 (see FIG. 19).

  Then, as shown in FIG. 20, the tip 20 a of the holding unit 20 is moved to the supply position PT <b> 2, whereby the thin component 5 to be fed next is transferred to the holding unit 20. That is, the feeding operation can be executed for each of the plurality of thin parts 5 by repeatedly executing the series of steps shown in FIGS.

  When the feeding operation of the thin part 5 is stopped, the control unit 60 moves the holding part 20 to the supply part 40 side after the mounting unit 70 receives the thin part 5 at the delivery position PT1. Then, the tip 20a of the holding part 20 is stopped at the supply position PT2. Accordingly, the tip 20a of the holding unit 20 is retracted at the supply position PT2 in a state where the thin component 5 to be fed next is delivered from the supply unit 40.

<6. Advantages of feeding unit in embodiment of the present invention>
As described above, the feeding unit 10 (and the component processing apparatus 100 including the feeding unit 10) according to the embodiment of the present invention has a size corresponding to the radial size of the main body 6 as shown in FIGS. Thus, the thin part 5 whose feeding direction size (that is, the size along the direction in which the projecting part 7 projects from the lower flat surface 6a of the main body part 6) becomes small is targeted for feeding.

  Further, the feeding unit 10 supports the thin component 5 supplied through the supply port 40 a of the supply unit 40 on the terrace surface 22 that is one step lower than the upper surface 20 b of the holding unit 20. In addition, the feeding unit 10 supplies the thin part supported by the terrace surface 22 with the upper surface 20b of the holding unit 20 closed on the upper surface 20b of the holding unit 20, and the supply position immediately below the supply port 40a. Transport from PT2 to delivery position PT1 to mounting unit 70. Further, the feeding unit 10 adjusts the arrangement of the thin parts 5 at the delivery position PT1 by the adjusting unit 50 so that delivery to the mounting unit 70 can be appropriately executed at the delivery position PT1.

  Therefore, the thin part 5 having the flange part 6b (particularly, the thin part 5 in which the main body part 6 and the protruding part 7 are solid) is separated from the supply part 40 one by one, and ( 2) It can be stably conveyed from the supply position PT2 to the delivery position PT1, and (3) it can be delivered to the mounting unit 70 with high accuracy.

<7. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.

  (1) In the embodiment of the present invention, the control unit 60 has been described as a unit different from the feeding unit 10 and the attachment unit 70, but is not limited thereto. For example, the feeding unit 10 may have a dedicated control unit, and the feeding operation of the feeding unit 10 may be executed by the control unit. That is, the control unit 60 may be included in the feeding unit 10 as a control unit constituting the feeding unit 10. Similarly, the mounting unit 70 also has a dedicated control unit, and the caulking operation of the mounting unit 70 may be executed by this control unit.

  (2) In the embodiment of the present invention, it has been described that at least a part of the thin part 5 is formed of a magnetic material, and the attracting portion 71c of the punch 71 is configured by a permanent magnet. It is not limited. For example, the attracting part 71c may be configured by an electromagnet.

  (3) In the embodiment of the present invention, the suction portion 71c of the punch 71 has been described as receiving the thin part 5 from the feeding unit 10 by magnetic force, but is not limited thereto. For example, the suction portion 71c may be configured to receive the thin part 5 by a suction force (for example, a suction force caused by intake air).

  (4) Moreover, in embodiment of this invention, although the shape of the notch 21 seen from the supply part 40 side was demonstrated as the U-shape, it is not limited to this. For example, the shape of the notch 21 viewed from the supply unit 40 side may be V-shaped.

  (5) In the embodiment of the present invention, when the feeding operation of the thin component 5 is stopped, the supply position PT2 is described as the retracted position of the tip 20a of the holding portion 20, but the present invention is not limited to this. It is not what is done.

  FIG. 21 is a side view for explaining another example of the feeding operation of the thin part 5 by the feeding unit 10. For example, when an air cylinder that can achieve a two-stage stroke and can be stopped at a position PT3 other than the delivery position PT1 and the supply position PT2, the position PT3 may be set as the retracted position of the holding unit 20 is used. good.

  That is, the control unit 60 causes the attachment unit 70 to receive the thin part 5 at the delivery position PT1, and then closes the supply port 40a of the supply unit 40 on the upper surface 20b of the holding unit 20 toward the supply unit 40 side. The holding part 20 is moved. Then, the control unit 60 stops the tip 20a of the holding unit 20 at a position PT3 between the delivery position PT1 and the supply position PT2.

  Thereby, the front-end | tip 20a of the holding | maintenance part 20 is evacuated in position PT3. Thus, unlike the case of FIG. 20, the feeding operation of the feeding unit 10 can be stopped without supporting the thin part 5 on the terrace surface 22 of the holding unit 20.

  (6) Furthermore, in the embodiment of the present invention, it has been described that an air cylinder is employed as the cylinder 31 of the drive unit 30, but the present invention is not limited to this. As the cylinder 31, a hydraulic, hydraulic or electric cylinder may be employed. Further, a stepping motor or a servo motor may be employed as a drive source for the drive unit 30.

  Similarly, although it has been described that an air cylinder is employed as the elevating unit 75, the present invention is not limited to this. As the raising / lowering unit 75, a hydraulic, hydraulic or electric cylinder may be employed. Further, a stepping motor or a servo motor may be employed as a driving force source for the elevating unit 75.
