[0034] Hereinafter, as an embodiment of the present disclosure, a laminate manufacturing apparatus and a motor core manufacturing system will be described with reference to the accompanying drawings. For ease of description, the size of each component shown in the accompanying drawings may be different from the actual size of each component.

[0035] For the convenience of description, reference will be made to an “up-down direction”, a “left-right direction”, and a “front-rear direction” as appropriate. Here, the “up-down direction” is a direction including an “upward direction” and a “downward direction”. The “left-right direction” is a direction including a “rightward direction” and a “leftward direction”. The “front-rear direction” means a “forward direction” and a “backward direction”. In the drawings described below, reference symbol U indicates an upward direction. Reference symbol D indicates a downward direction. Reference symbol F indicates a forward direction. Reference symbol B indicates a backward direction. Reference symbol L indicates a leftward direction. Reference symbol R indicates a rightward direction. The “horizontal direction” is a direction including a “left-right direction” and a “front-rear direction”.

[0036] Figure 1 is a schematic diagram of a part of an apparatus 1 for producing a laminate W2. Figure 2 : is a diagram showing the lower mold 12 and the portion below the lower mold 12 in the device 1 for manufacturing the laminate W2, and the post-stamping processing device 5. The device 1 for manufacturing the laminate W2 punches the sheet workpiece W1 to form a stamped component, and laminates the stamped component to manufacture the laminate W2. The stamped component is an example of a workpiece after stamping. The workpiece W1 wound into a coil is supplied from the uncoiler 2 and fed to the manufacturing device 1 by the feeding device 4 via the leveler 3, and the leveler 3 corrects the curling of the workpiece W1. In this embodiment, the case where the workpiece W1 is an electromagnetic steel sheet and the laminate W2 manufactures a motor core is illustrated, and the motor core is the core part in the rotor or stator of a rotating motor. The manufacturing device 1 and the post-stamping processing device 5 constitute at least a part of the motor core manufacturing system.

[0037] like Figure 1 and Figure 2As shown, the manufacturing equipment 1 includes a mold unit 10, a base 20 and a support part 30. The mold unit 10 includes an upper mold 11 and a lower mold 12. The workpiece W1 is fed between the upper mold 11 and the lower mold 12. The upper mold 11 includes a stamping punch 111. The upper mold 11 is configured so that the upper mold 11 is displaced in the up and down directions by a driving device (not shown). The lower mold 12 is arranged below the upper mold 11. A mold hole 12a is formed in the lower mold 12, into which a part of the stamping punch 111 can be inserted. When the workpiece W1 is located between the upper mold 11 and the lower mold 12, the upper mold 11 is displaced downward so that a part of the stamping punch 111 is inserted into the mold hole 12a, thereby stamping the workpiece W1 to form a stamped component. The stamped component is conveyed downward through the mold hole 12a.

[0038] The lower mold 12 further includes an ejector 12b. The ejector 12b ejects the laminated body W2 manufactured by laminating the punching members toward the first conveying path P1 described later. The ejector 12b may have a different pushing direction from that of the present embodiment.

[0039] The base 20 includes a leg 21 in contact with the floor FL and a placement table 22 on which the lower mold 12 is placed. The leg 21 includes a ground plane in contact with the floor FL on which the manufacturing apparatus 1 is placed. The leg 21 supports the placement table 22 from below, and the placement table 22 supports the lower mold 12 from below.

[0040] The support portion 30 is configured to support a punched member from below when the punched member is formed by punching the workpiece W1. The support portion 30 includes a pad 31 that contacts the punched member and supports the punched member from below.

[0041] The support part 30 includes a cylinder having a hydraulic chamber therein and a rod arranged to be movable forward and backward in the cylinder. The cylinder is fixed to the base 20. A pad 31 is arranged at the top of the rod. Therefore, the support part 30 is configured to be telescopic in the up and down direction. By changing the length of the rod extending from the cylinder, the height of the supporting stamping member can be adjusted.

[0042] The support portion 30 is disposed so that the lower end portion 301 of the support portion is located above the ground plane. The support portion 30 is disposed so that the lower end portion 301 of the support portion is located below the upper surface 121 of the lower mold 12. In other words, the support portion 30 is disposed in a state of being suspended from the floor FL on which the manufacturing apparatus 1 is placed.

[0043] Next, a method of manufacturing the laminated body W2 using the support portion 30 will be described. Figure 3 The support 30 is shown in relation to the lamination step. Figure 4 The support portion 30 associated with the first conveying step is shown. The method of manufacturing the laminated body W2 includes a laminating step, a first conveying step, a second conveying step, and a third conveying step.

[0044] The laminating step includes supporting the laminate W2 from below by a support portion 30 disposed between the floor panel FL and the lower mold 12. Figure 3 As shown, in the lamination step in which the stamping member is being manufactured and the laminate W2 is being manufactured, the laminate W2 contacts the die hole 12a and is pressed in the central axis direction of the laminate W2. At this time, the support portion 30 supports the laminate W2 in a relatively extended state. When the laminate W2 is pressed in the central axis direction thereof, the laminate W2 is easily deformed to bend downward, but the downward bending of the laminate W2 can be suppressed by supporting the laminate W2 from below using the support portion 30.

[0045] The support portion 30 controls the protruding length of the rod by adjusting the hydraulic pressure inside the cylinder, and changes the length of the support portion 30 according to the number of laminated stamping members, etc. For example, when the number of stamping members laminated on the pad 31 is small, the rod advances and the support portion 30 extends relatively long. When the number of stamping members laminated on the pad 31 increases, the hydraulic pressure is controlled so that the rod retracts and the support portion 30 contracts.

[0046] The releasing step includes releasing the laminate W2 from the lower mold 12. In the releasing step, when lamination of the punching member is completed and the laminate W2 is completed, the laminate W2 is released downward from the mold hole 12a of the lower mold 12. The laminate W2 released downward from the mold hole 12a of the lower mold 12 is pushed forward by the ejector 12b.

[0047] The first conveying step includes conveying the released laminated body via the first conveying path P1 at a position higher than the support 40. In the first conveying step, the laminated body W2 pushed out by the ejector 12b is further conveyed forward by the first conveying path P1 (see Figure 2 ).

[0048] The second conveying step includes lowering the laminate W2 via a second conveying path P2 connected to the first conveying path P1. Figure 2 As shown, in the second conveying step of the present embodiment, the laminated body W2 conveyed forward by the first conveying path P1 is fed downward through the second conveying path P2.

[0049] The third conveying step includes conveying the descending laminate W2 via the third conveying path P3 connected to the second conveying path P2 and located at a position below the bracket 40. In the third conveying step, the laminate W2 conveyed downward by the second conveying path P2 is fed to the post-stamping processing device 5 through the third conveying path P3. In the post-stamping processing device 5, embedding a permanent magnet in the laminate W2, molding, welding, measuring, and inspecting the resin material can be performed. The details of the first conveying path P1, the second conveying path P2, and the third conveying path P3 will be described later.

[0050] Figure 5 A manufacturing apparatus and a support portion 30A according to a comparative example are shown. In the manufacturing apparatus according to the comparative example, the stamping member can be laminated while being supported from below by the support portion 30A. However, the manufacturing apparatus according to the comparative example is different from the manufacturing apparatus according to the present embodiment in that a groove is formed in the floor on which the manufacturing apparatus according to the comparative example is placed, and therefore, the lower end portion 301A of the support portion 30A is disposed below the ground plane of the base 20A. In the manufacturing apparatus according to the comparative example, the mold unit 10A is disposed at a position lower than the height of the operator to facilitate maintenance of the mold.

[0051] In such Figure 5 In the manufacturing apparatus shown, the mold unit 10A is generally configured to be arranged at a portion close to the ground, mainly to facilitate the maintenance work of the mold. Therefore, by forming a groove in the floor, the lower end portion 301A of the support portion 30A for supporting the laminate W2 from below is arranged below the floor.

[0052] However, in recent years, the proportion of post-stamping processing equipment in the manufacturing system has increased, such as the number of processing steps and inspection steps performed on each processing step. In addition, when the specifications of the laminate W2 to be manufactured change, the layout and length of the post-stamping processing equipment also change. Therefore, considering the balance with the post-stamping processing equipment, the equipment for manufacturing the laminate W2 also needs to be constructed to be easy to rearrange. However, when there is a groove for setting the support portion 30A as in the comparative example, it is difficult to set other equipment at the location where the equipment for manufacturing the laminate W2 is located. In addition, it is necessary to form a new groove at the location where the newly set equipment for manufacturing the laminate W2 is located. As described above, for the manufacturing equipment of the laminate W2, it is desirable to increase the degree of freedom of rearrangement of the manufacturing equipment rather than the accessibility of the mold.

[0053] In the manufacturing apparatus 1 of the present embodiment, the lower end portion 301 of the support portion 30 is disposed at the same position as the ground plane of the base 20 or above the ground plane. Therefore, when the manufacturing apparatus 1 is set, a groove may not be formed in the floor FL, and the manufacturing apparatus 1 may be set on a flat floor FL. Therefore, even if it is necessary to rearrange the apparatus 1 for manufacturing the laminate W2, it is easy to rearrange other devices to the position where the apparatus 1 for manufacturing the laminate W2 was previously located, and time and effort required to set up the apparatus 1 for manufacturing the laminate W2 at a new arrangement position can be saved.

[0054] The manufacturing system 100 of the motor core of the present embodiment includes an apparatus 1 for manufacturing a laminate W2 and a post-stamping processing apparatus 5, and the apparatus 1 for manufacturing a laminate W2 and the post-stamping processing apparatus 5 are installed on a common floor FL at the same height. Therefore, the workload associated with rearrangement can be reduced. In particular, since the present manufacturing system 100 does not require a groove for installing a stamping device, the workload associated with reinstalling the stamping device can be omitted. In addition, since it is easy to set other devices at the location where the stamping device is installed, the degree of freedom of setting the entire manufacturing system 100 of the motor core is improved.

[0055] Figure 6 is from Figure 2 The view that the VI observes in the direction of the arrow. Figure 2 and Figure 6 As shown, the manufacturing device 1 of this embodiment includes a bracket 40. In this embodiment, the bracket 40 is arranged to surround the manufacturing device 1. Figure 2 As shown, the height of the bracket 40 is preferably higher than the ground plane of the base 20 and lower than the upper surface 121 of the lower mold 12 .

[0056] exist Figure 5 In the comparative example shown, a groove is formed in the floor FL, and easy access to the mold unit 10A is ensured. Figure 6 In the example shown, since no groove is formed in the floor FL, the height from the floor FL to the mold unit 10 tends to be high. Figure 6 In the example shown, since the support 40 is disposed at a height above the ground plane of the base 20 and below the upper surface 121 of the lower mold 12 , easy access to the mold unit 10 is maintained.

[0057] In addition, if Figure 2 As shown, in this embodiment, a step portion 41 is provided that reaches the upper surface of the bracket 40. Therefore, a worker can easily access the mold unit 10.

[0058] The manufacturing equipment 1 of the present embodiment includes a first conveying path P1, a second conveying path P2 and a third conveying path P3. The first conveying path P1 is configured to carry out the manufactured laminate W2 in a horizontal direction from directly below the lower mold 12. The second conveying path P2 is configured to lower the laminate W2 conveyed by the first conveying path P1. The third conveying path P3 is configured to convey the laminate W2 conveyed by the second conveying path P2 to the post-stamping processing equipment 5 in a horizontal direction. The first conveying path P1 and the second conveying path P2 are connected to each other, and the second conveying path P2 and the third conveying path P3 are connected to each other. The first conveying path P1 and the third conveying path P3 can be, for example, a belt conveyor. The second conveying path P2 is an example of a lifting part. The second conveying path P2 can be an elevator that returns upward after conveying the laminate W2 downward. The direction in which the first conveying path P1 and the third conveying path P3 convey the laminate W2 is not limited to the example of the present embodiment.

[0059] The first conveying path P1 is set at substantially the same height as the upper surface of the base 20. The second conveying path P2 as the lifting portion is configured to lower the laminate W2 from a height substantially equal to the upper surface of the base 20 to a height above the ground plane and below the support 40. Therefore, since the third conveying path P3 is set at a height lower than the support 40, the manufacturing apparatus 1 of the present embodiment can easily provide better workability for workers working in the post-press processing apparatus 5.

[0060] like Figure 2 and Figure 6 As shown, the second conveying path P2 as the lifting portion is provided so that a part of its side surface is surrounded by the bracket 40. In other words, the second conveying path P2 is provided to pass through the bracket 40.

[0061] A portion of the third transport path P3 is disposed below the support 40. “Below the support 40” refers to an area covered by the support 40 when viewed from above. Figure 6 As shown, the laminate W2 descended by the second conveying path P2 is conveyed in the left direction under the support 40. Thereafter, the laminate W2 is conveyed in the forward direction. At this time, the third conveying path P3 conveying the laminate W2 in the left direction and a portion of the third conveying path P3 conveying the laminate W2 forward are covered by the support 40 when viewed from above.

[0062] The third conveying path P3 of the present embodiment is provided so that at least a portion thereof passes under the rack 40. Therefore, space saving can be achieved in the manufacturing apparatus 1 including the third conveying path P3 and the rack 40.

[0063] like Figure 2 and Figure 6As shown, the manufacturing apparatus 1 of the present embodiment includes a soundproof wall 50. The soundproof wall 50 is provided to cover at least one side and an upper side of the mold unit 10. As in the present embodiment, the soundproof wall 50 may also be provided to cover one side of the base 20. In addition, in order to improve accessibility to the mold unit 10, a door (not shown) may be provided on the side of the soundproof wall 50.

[0064] An opening is formed in the soundproof wall 50. The size of the opening is formed so that the laminated body W2 carried out from just below the lower mold 12 by the first transport path P1 can pass through the opening.

[0065] Since the manufacturing apparatus 1 of the present embodiment includes the soundproof wall 50, the influence of noise associated with the manufacturing of the laminate W2 on the surrounding environment can be suppressed. In addition, since an opening is formed in the soundproof wall 50, the laminate W2 can be easily and smoothly carried out even if the soundproof wall 50 is provided.

[0066] The method for manufacturing the laminated body W2 of the present embodiment is a method for manufacturing the laminated body W2 using the above-mentioned manufacturing apparatus 1. Therefore, an effect equivalent to that of the above-mentioned manufacturing apparatus 1 can be obtained.

[0067] Since the manufacturing method of the laminate W2 of the present embodiment includes a lamination step in which the laminate W2 is supported from below by the support portion 30 provided between the floor panel FL and the lower mold 12, it is not necessary to form a groove in the floor panel FL for providing the support portion 30. Therefore, the degree of freedom in arrangement of the apparatus 1 for manufacturing the laminate W2 is improved.

[0068] In addition, the manufacturing method of the laminate W2 of the present embodiment includes a second conveying step and a third conveying step. In the second conveying step, the laminate W2 located at a position higher than the support 40 is vertically dropped via the second conveying path P2. In the third conveying step, the laminate W2 is conveyed in the horizontal direction via the third conveying path P3 connected to the second conveying path P2 and located at a position lower than the support 40. Since the support portion is arranged between the floor and the lower mold, when the laminate is conveyed to the post-stamping processing equipment at the height of the first conveying path, the laminate is fed far from the floor, so the workability in the post-stamping processing equipment is poor. However, since the laminate W2 is conveyed at a height close to the floor FL through the second conveying step and the third conveying step, the workability in the steps after the laminate W2 is manufactured is improved.

[0069] Although the embodiments of the present disclosure have been described above, it is needless to say that the technical scope of the present disclosure should not be understood as being limited by the description of the embodiments. It should be understood by those skilled in the art that the present embodiments are merely examples, and that various modifications may be made to the embodiments within the scope of the invention described in the claims.
