Description

Technical Field

[0001] The present disclosure relates to an apparatus for producing a laminated body and a method for producing a laminated body. Background Art

[0002] Conventionally, in order to obtain a motor core (rotor core or stator core) used in a motor mounted in an electric vehicle or the like, a laminated body is produced by laminating a plurality of core members.

[0003] Japanese Patent Application Publication No. 2019-118169 describes a plate lamination device for manufacturing laminated bodies that constitute a stator core. This device features a sensor that detects the passage of plates fed from a cylinder serving as a conveyor path, and a partitioning mechanism that supports the plates, located near the cylinder's exit. Based on the sensor's detection results, the partitioning mechanism projects onto the plate conveyor path at a desired timing, halting the conveyance of the plates. This allows the number of plates fed to the fixture and the timing of their delivery to be controlled. Summary of the Invention

[0004] Problems to be solved by the invention

[0005] As described in Japanese Patent Application Publication No. 2019-118169, if the protrusion timing of the partition mechanism is determined only based on the detection results of the sensor that senses the passage of the plate output from the cylinder, when the plate output speed from the cylinder is fast, the time from sensing the passage of the plate to completing the action of the partition mechanism will become extremely short. Therefore, the actuator, sensor and their control device of the partition mechanism are required to have a fast response speed, and the difficulty of their control will also increase. In addition, for example, when the action speed of the partition mechanism decreases due to the degradation of the actuator of the partition mechanism over the years, the following undesirable situation may occur: before the action of the partition mechanism is completed, the plate whose conveyance should be stopped arrives, and the conveyance of the plate cannot be stopped. Moreover, in order to make the partition mechanism operate with high precision, it is necessary to frequently confirm the degradation of the actuator of the partition mechanism over the years, and the maintenance frequency becomes high.

[0006] In addition, the invention of Japanese Patent Application Publication No. 2019-118169 uses a structure in which a fixture is used to receive the plate output from the cylinder. However, generally speaking, the shape of such a fixture is different to match the shape of the plate to be output. In addition, when it is desired to continuously manufacture the same stacked body, it is preferable to prepare multiple fixtures of the same shape in advance in order to smoothly perform fixture replacement operations. Therefore, when the invention of Japanese Patent Application Publication No. 2019-118169 is used to manufacture various stacked bodies, it may be necessary to prepare multiple fixtures of different shapes in advance.

However, the detailed description and specific examples are ideal embodiments of the present disclosure and are recorded only for illustrative purposes. This is because, within the spirit and scope of the present disclosure, various changes and modifications based on the detailed description will be apparent to those skilled in the art.

[0072] The applicant does not intend to dedicate any of the described embodiments to the public, and disclosed variations and alternatives that may not literally be included in the claims are also intended to be part of the invention under the doctrine of equivalents.

[0073] Hereinafter, various embodiments for implementing the present disclosure will be described with reference to the accompanying drawings. It should be noted that, below, the scope required for the description to achieve the purpose of this disclosure is schematically shown, and the scope required for the description of the corresponding parts of the present disclosure is mainly described, and the parts that are omitted will be based on the known technology. In addition, the same or similar reference numerals are marked on the components that are identical or equivalent to each other in the figures, and repeated descriptions are omitted. Moreover, in the case where a plurality of identical or equivalent components are included in a figure, in order to facilitate the understanding of the figure, sometimes only some of the components are marked with reference numerals. Moreover, in addition, as long as there is no special explanation in the specification, there may be multiple components of the present disclosure, and it is not limited to one.

[0074] <First embodiment>

[0075] In the manufacturing apparatus 1 of the laminated body of the first embodiment (see Figure 3 ) and the method for manufacturing the laminate, a brief description will be given of the core components constituting the laminate. In this embodiment, a plurality of laminated core components can be stacked to form a block core, which can constitute a motor core alone or a plurality of them can be stacked to form a motor core, such as a stator core of an inner rotor type rotating motor. It should be noted that the "laminated body" in this disclosure refers to a structure in which a plurality of core components are simply stacked, and a structure in which the laminate is joined by welding or the like is referred to as a "motor core" to distinguish between the two. In addition, the above-mentioned motor core can be any of a split stator core and a non-split stator core, and can also constitute a rotor core instead of a stator core.

[0076] Furthermore, the core member may be composed of two types: a locking core member 10 having locking tabs 13 at multiple locations on its outer circumference, and a non-locking core member 20. The locking core member 10 has locking tabs 13 at multiple locations on its outer circumference, while the non-locking core member 20 does not have the aforementioned locking tabs 13. The respective configurations of the locking core member 10 and the non-locking core member 20 are described below.

[0077] Figure 1 1 is a diagram showing an example of a locking core member supplied to the manufacturing apparatus of the laminated body according to the first embodiment of the present disclosure. Figure 1 As shown, the locking core member 10 may include: an annular yoke 11 having a through-hole formed in its center for receiving the rotor core; teeth 12, which are generally T-shaped when viewed from above and are provided on the inner circumference of the yoke 11 so as to protrude toward the center of the yoke 11; and locking tabs 13, which are formed as protrusions extending outward from the outer circumference of the yoke 11. Furthermore, the locking core member 10 may be formed from a single plate-shaped electromagnetic steel sheet (sometimes referred to as a "core sheet") having a predetermined wall thickness.

[0078] The teeth 12 provided on the inner circumference of the locking core member 10 can be provided in multiple numbers at approximately equal intervals along the inner circumference, for example, eight teeth. When assembled into the stator core, armature coils can be wound around the teeth 12. It should be noted that the specific shape and arrangement of the teeth 12 can be modified as appropriate.

[0079] The locking pieces 13 provided on the outer peripheral surface of the locking core member 10 may be provided in plurality at substantially equal intervals along the outer periphery of the locking core member 10, for example, four. Figure 1 As shown, the four locking tabs 13 are preferably positioned radially outward from any of the eight teeth 12 located on the inner circumference of the locking core member 10. Generally, the density of the magnetic flux generated radially outward from the teeth 12 when the locking core member 10 operates as part of the motor core tends to be lower than at other locations. Therefore, when the locking tabs 13 are positioned radially outward from the teeth 12 as described above, degradation of the magnetic properties of the motor core caused by the placement of the locking tabs 13 can be suppressed.

[0080] Figure 2 1 is a diagram showing an example of a non-locking core member supplied to the manufacturing apparatus of the laminated body according to the first embodiment of the present disclosure. Figure 2 As shown, the non-locking core component 20 may include: a circular yoke 21, a through hole formed in the center portion of which the rotor core is arranged; and teeth 22, which are roughly T-shaped when viewed from above and are arranged on the inner peripheral surface of the yoke 21 in a manner protruding toward the center portion of the yoke 21. In addition, the non-locking core component 20 can also be composed of a plate-shaped electromagnetic steel plate with a specified wall thickness. In other words, except for not having the locking piece 13 included in the above-mentioned locking core component 10, the non-locking core component 20 can include the same structure as the locking core component 10. Therefore, the yoke 11 and teeth 12 of the locking core component 10 can have the same size, configuration and number as the yoke 21 and teeth 22 of the non-locking core component 20.

[0081] The following describes an apparatus and method for manufacturing a laminated body using the aforementioned structure of the locking core member 10 and the non-locking core member 20. It should be noted that the specific structure of the locking core member 10 and the non-locking core member 20 is not limited to the above-described structure and can be modified in various ways. Representative examples will be described later.

It should be noted that, hereinafter, Figure 3 The direction indicated by the arrow X shown in the figure is the left-right direction. Similarly, the following description will be given with the direction indicated by the arrow Y as the front-back direction and the direction indicated by the arrow Z as the up-down direction.

[0085] The feeding mechanism 30 may include a punching machine that can Figure 3The strip steel plate 2 conveyed in the direction of arrow A1 in the figure selectively punches and forms the locked core members 10 and the non-locked core members 20. The feeding mechanism 30 may include a die (sometimes also referred to as a lower die) 31 that supports a portion of the strip steel plate 2 together with a support table 33 that supports the conveyed strip steel plate 2, and a punch (sometimes also referred to as an upper die) 32 provided on the upper part of the die 31. The punch 32 is along the Figure 3 The locking core member 10 and the non-locking core member 20 can be punched out from the strip steel plate 2 by operating in the direction of arrow A2 in FIG.

[0086] Figure 4 It is along Figure 3 The extrusion member 40 is arranged on the downstream side of the supply mechanism 30 in the conveying direction, and supports the locking core member 10 and the non-locking core member 20 supplied from the supply mechanism 30 from the side and can convey them along the conveying direction. Figure 3 and Figure 4 As shown, the extrusion 40 can be composed of a substantially cylindrical member, one end of which is connected to the downstream end of the die 31 in the conveying direction. The extrusion 40 is preferably assembled on the support table 33 together with the die 31. The extrusion 40 can convey the locked core members 10 and the non-locked core members 20 that have been punched and pressed out from under the die 31 in a stacked state.

[0087] In addition, if Figure 4 As shown, the inner circumferential surface 41 of the extrusion piece 40 can be adjusted to a size that matches the shape of the locking core component 10 and the non-locking core component 20 to be transported. Thus, the sides (i.e., the outer periphery) of the locking core component 10 and the non-locking core component 20 passing through the extrusion piece 40 can be supported in abutment with the inner circumferential surface 41 of the extrusion piece 40. It should be noted that the inner circumferential surface 41 of the extrusion piece 40 of the present embodiment is a shape that matches the outer peripheral shape of the locking core component 10, but other structures can also be used as long as it is a structure that can support the locking core component 10 and the non-locking core component 20 from the side. For example, it can also be set to a shape in which the inner circumferential surface 41 only abuts against a portion of the outer circumferential surface of each core component. In addition, Figure 3 , Figure 8 described later, Figure 10 13 and the like illustrate a case where the number of core members transported within the extrusion 40 is relatively small for ease of understanding. However, the number of core members that can be transported within the extrusion 40 can be tens to hundreds. Furthermore, the total number of core members constituting the laminate can also be tens to hundreds.

[0088] The locking core components 10 and non-locking core components 20 continuously supplied from the supply mechanism 30 can be sequentially input and supported on the upper end of the extrusion 40. Therefore, whenever a locking core component 10 or a non-locking core component 20 is newly input into the extrusion 40, the locking core components 10 and non-locking core components 20 already held in the extrusion 40 will be pressed by the delivered locking core component 10 or non-locking core component 20 and transported downward in the extrusion 40 by an amount corresponding to its wall thickness. It should be noted that, in Figure 3 , Figure 8 described later, Figure 10 As described above, in order to facilitate understanding of the boundaries between the core components, as well as in Figure 13 and other figures, a small gap is shown between the core components, but in reality, no such gap is formed. That is, the adjacent locking core components 10 and non-locking core components 20 within the extrusion 40 in this embodiment are conveyed in a stacked state, in other words, in contact with each other. The same applies to the locking core components 10 and non-locking core components 20 shown in Figures 8 and 13 after being conveyed onto the conveyor 60.

[0089] The separation mechanism 50 controls the supply of the locked core members 10 and unlocked core members 20 being transported downward to the conveyor 60. The separation mechanism 50 includes at least a locking portion 51 that contacts the transported locked core members 10 to restrict their movement, and an actuator 52, which is an example of a working device that actuates the locking portion 51. It should be noted that the downward direction described above corresponds to the conveyance direction of the core members 10 and 20 in this embodiment.

[0090] Figure 5 It is along Figure 3 A schematic cross-sectional view obtained by cutting along the E-E line of FIG. Figure 3 and Figure 5 As shown, the locking portion 51 can be provided with a plurality of locking portions around each core member being transported, specifically, four locking portions 51 are provided to match the number of locking pieces 13 provided on the locking core member 10. The locking portion 51 can be configured to be able to lock at the locking position P1 (refer to Figure 8B ) and the non-locking position P2 (refer to Figure 8A ) between the moving and locking positions P1. Figure 5 As shown in FIG, each of the plurality of locking pieces 13 of the locking core member 10 output from the end portion of the downstream side in the conveying direction of the extruded member 40 is locked. The non-locking position P2 is as shown in FIG. Figure 3 In other words, the locking position P1 can be set at any position on the moving path of the locking piece 13 of the locking core member 10 transported on the conveying path, and the non-locking position P2 can be set at a position that does not overlap with the moving path of the locking piece 13. It should be noted that, in Figure 5In order to facilitate understanding of the relationship between the locking piece 13 and the locking portion 51, the locked core member 10 transported at this position is shown by a dotted line, and members located below the partition mechanism 50, such as the conveyor belt 60, are omitted from the illustration.

[0091] The actuator 52 can operate the locking portion 51. Specifically, the locking portion 51 can be moved between the locking position P1 and the non-locking position P2 along the axis of the locking portion 51. Figure 5 The actuator 52 of this embodiment can adopt a well-known direct-acting device such as a cylinder or a single-axis robot. Through the actuator 52, the locking portion 51 can be moved in a manner of moving between a locking position P1 set in a direction relatively close to the locking core component 10 and a non-locking position P2 set in a direction relatively away from the locking core component 10. It should be noted that the moving direction of the locking portion 51 achieved by the actuator 52 is not limited to the above-mentioned direction, and can be appropriately changed to match the shape of the locking piece 13, etc.

[0092] Furthermore, the separator mechanism 50 of this embodiment may further include a sensor 53 capable of sensing when each core member has passed any position on its conveying path. This arbitrary position is preferably any position between the lower end of the extrusion member 40 and the upper end of the locking portion 51, and more preferably a position adjacent to the upper end of the locking portion 51. This sensor 53 may be a known sensing device, such as an infrared sensor, a two-dimensional camera, or the like.

[0093] Furthermore, the strength of the locking piece 13 of the locking core component 10 is generally determined by its wall thickness and material. In addition, when the partition mechanism 50 supports the locking core component 10, in addition to the weight of the locking core component 10 itself including the locking piece 13, the weight of the non-locking core components 20 output from the extrusion 40 and stacked on the locking core component 10 will also act on the locking piece 13. Therefore, the locking piece 13 may be deformed by these weights, making it impossible to control the supply of each core component to the conveyor belt 60. Taking this into consideration, in order to assist in the support of the locking core component 10 achieved by the locking piece 13, the manufacturing device 1 of this embodiment preferably also includes a holding mechanism 55.

[0094] like Figure 3 and Figure 5 As shown, the holding mechanism 55 can be provided at the same height position as the partition mechanism 50. In addition, the holding mechanism 55 can be provided at a locking position P3 (see FIG. 1 ) that can support at least a portion of the portion of the outer periphery of the core member 10 where the locking piece 13 is not provided. Figure 8C ) and a non-locking position P4 (refer to Figure 8A) to move between them. In order to stably support each core member, the length of the holding mechanism 55 along the direction of the outer peripheral surface of the locking core member 10 (hereinafter, such length will also be referred to as "width") is preferably set to be larger than the width of the locking portion 51. The working direction of the holding mechanism 55 can be determined by Figure 5 The direction indicated by the arrow A4 in FIG. 1 is the direction toward or away from the locked core member 10. By including such a holding mechanism 55, the locked core member 10 or the locked core member 10 and the non-locked core member 20 stacked therewith to be supplied to the conveyor 60 can be supported by both the partitioning mechanism 50 and the holding mechanism 55. Therefore, the supply of each core member to the conveyor 60 can be reliably controlled.

[0095] The conveyor belt 60 can be a member capable of receiving, through its upper surface, the locking core members 10 and the non-locking core members 20 supplied from the end portion of the extrusion member 40 on the downstream side of the conveying direction through the partition mechanism 50. When the conveyor belt 60 is operated, the locking core members 10 and the non-locking core members 20 supplied and placed on the conveyor belt 60 can be conveyed in a direction intersecting the conveying direction, such as the front-to-back direction (hereinafter referred to as the "conveyor belt conveying direction"). It should be noted that the specific structure of the conveyor belt 60 is not particularly limited, but, for example, a well-known belt conveyor device (belt conveyor) can be used.

[0096] The conveyor belt 60 of this embodiment does not require a structure for limiting the horizontal position of the supplied latching core members 10 and non-latching core members 20. This is because the horizontal positions of the latching core members 10 and non-latching core members 20 are already positioned by the positioning mechanism 70 described later. It is preferable that the conveyor belt 60 of this embodiment does not require a positioning structure for latching core members 10 and non-latching core members 20 because the structure of the conveyor belt 60 can be simplified and the placement positions of the latching core members 10 and non-latching core members 20 can be freely changed.

[0097] Figure 6 is from Figure 3 The F-F line shows the schematic structure of the position observed, and Figure 6A The figure shows the state where the positioning mechanism is in the positioning release position with the core member placed on the conveyor belt. Figure 6B The figure shows the positioning mechanism in the positioning position with the core member placed on the conveyor belt. Figure 3As shown in FIG6 , the positioning mechanism 70 is disposed between the end portion of the extrusion piece 40 on the downstream side of the conveying direction and the conveyor belt 60 to position the latching core member 10 and the non-latching core member 20 to be supplied to the conveyor belt 60. The positioning mechanism 70 can move toward and away from the side surface of the core member supplied from the end portion of the extrusion piece 40 on the downstream side of the conveying direction. Figure 3 In the figure, the positioning mechanism 70 is shown in cross section, and for the positioning piece 71 on the right side of the figure, the cross section obtained by cutting at a position opposite to the locking piece 13 is shown, and for the positioning piece 71 on the left side of the figure, the cross section obtained by cutting at a position constituting the abutment surface 72 is shown.

[0098] The positioning mechanism 70 can be composed of a plurality of, for example, two, positioning pieces 71 arranged around the outer periphery of the locking core member 10 and the non-locking core member 20 carried on the conveyor belt 60. The plurality of positioning pieces 71 include abutment surfaces 72 that are opposed to the side surfaces of the locking core member 10 and the non-locking core member 20 carried on the conveyor belt 60. As shown in FIG6 , the abutment surfaces 72 of this embodiment can be formed by a surface that is curved along the side shape of the locking core member 10 and the non-locking core member 20 when viewed from above, so as to be able to abut the side surfaces of the locking core member 10 and the non-locking core member 20. It should be noted that the shape of the abutment surface 72 is not limited to the above-mentioned shape as long as it can position the locking core member 10 and the non-locking core member 20. For example, it can also be a shape that abuts only a portion of the outer periphery of the locking core member 10 and the non-locking core member 20. In addition, a pin can be provided on the positioning piece 71 and the pin side surface can be used as the abutment surface.

[0099] In addition, in this embodiment, the positioning of the locking core member 10 and the non-locking core member 20 is performed by making the abutting surfaces 72 of the plurality of positioning pieces 71 abut against the locking core member 10 and the non-locking core member 20, but the present disclosure is not limited to this. Specifically, as long as the locking core member 10 and the non-locking core member 20 are located in the area between the abutting surfaces 72, positioning can be performed even if the abutting surfaces 72 do not abut against the locking core member 10 and the non-locking core member 20. Therefore, it is also possible that the side surfaces of the locking core member 10 and the non-locking core member 20 only abut against a portion of the abutting surfaces 72, or the abutting surfaces 72 only face all the side surfaces of the locking core member 10 and the non-locking core member 20 across a predetermined gap. It should be noted that the aforementioned predetermined gap can be set to be at least smaller than the gap between the abutting surface 72 and the locking core member 10 and the non-locking core member 20 in the positioning release position P6.

[0100] As described above, the abutting surface 72 is composed of a surface curved along the side shape of the locking core member 10 and the non-locking core member 20, and therefore, can support the core member 10 and the non-locking core member 20 placed on the conveyor belt 60 from various directions. Therefore, for the locking core member 10 and the non-locking core member 20 positioned by the abutting surface 72, the horizontal positioning will be stably implemented. It should be noted that it is better to form a recessed portion in the front-to-back central portion of the abutting surface 72 at a position of the positioning piece 71 opposite to the locking piece 13, so that when the positioning piece 71 moves, the movement of the positioning piece 71 to the positioning position P5 will not be hindered by the contact between the abutting surface 72 and the locking piece 13. In this case, when the positioning piece 71 is moved to the positioning position P5, as shown in FIG. Figure 6B As shown, the locking piece 13 of the locking core member 10 placed on the conveyor belt 60 is accommodated in the recessed portion of the above-mentioned abutment surface 72. By avoiding contact between the locking piece 13 of the locking core member 10 placed on the conveyor belt 60 and the abutment surface 72, the above-mentioned positioning can be reliably implemented. It should be noted that, in the case where there are convex portions between the locking core member 10 and the non-locking core member 20, as described above, it is sufficient to provide a recessed portion on the abutment surface 72. In the case where there are recessed portions between the locking core member 10 and the non-locking core member 20, it is better to provide a convex portion on the abutment surface 72.

[0101] In the above embodiment, the example of preventing contact between the abutment surface 72 and the locking piece 13 by providing a recessed portion in the positioning piece 71 is shown, but the present disclosure is not limited to this. For example, when the positioning piece 71 is in the positioning position P5, a portion of the recessed portion of the positioning piece 71 may be actively brought into contact with the locking piece 13, thereby assisting the positioning performed by the abutment surface 72. In this case, it is expected that the stability of the positioning of the stacked body by the positioning piece 71 will be improved.

[0102] In this embodiment, the positioning mechanism 70 is exemplified as comprising a pair of positioning pieces 71, wherein the contact surfaces 72 of the pair of positioning pieces 71 are opposed to each other across the conveyor belt 60 when viewed from above. However, the arrangement and number of positioning pieces 71 may be appropriately modified. For example, four positioning pieces may be provided so as to surround the outer periphery of the locking core member 10 and the non-locking core member 20 placed on the conveyor belt 60 in the front-to-back direction and the left-to-right direction.

[0103] Furthermore, the plurality of positioning pieces 71 may be movable between a positioning position P5 where the contact surface 72 contacts the side surfaces of the locking core member 10 and the non-locking core member 20 placed on the conveyor 60, or where the contact surface 72 faces the side surfaces of the locking core member 10 and the non-locking core member 20 with a slight gap therebetween, and a positioning release position P6 where the side surfaces of the locking core member 10 and the non-locking core member 20 placed on the conveyor 60 are separated from the contact surface 72. A known drive device (not shown) may be used to move the plurality of positioning pieces 71.

[0104] If the plurality of positioning pieces 71 are positioned at the positioning position P5 described above, the locked core members 10 and the non-locked core members 20 discharged from the extrusion piece 40 can be positioned at desired positions on the conveyor 60. Furthermore, if the plurality of positioning pieces 71 are positioned at the positioning release position P6 described above, when the locked core members 10 and the non-locked core members 20 placed on the conveyor 60 are moved in the conveying direction of the conveyor, the positioning pieces 71 do not hinder their movement.

[0105] The contact surface 72 may include a tapered surface 73 that approaches the side surfaces of the locking core member 10 and the non-locking core member 20 placed on the conveyor 60 as it moves downstream in the conveying direction. In this embodiment, the entire upper portion of the contact surface 72 is provided as the tapered surface 73. When the tapered surface 73 is formed on the contact surface 72 in this manner, even if the posture or horizontal position of the locking core member 10 and the non-locking core member 20 discharged from the extrusion 40 is offset, the locking core member 10 and the non-locking core member 20 can be guided to the desired position on the conveyor 60.

[0106] In order to reliably implement the positioning of the fixed core components 10 and the non-fixed core components 20 placed on the conveyor belt 60, it is preferable to adjust the height positions of the multiple positioning pieces 71. Specifically, the ends of the abutting surfaces 72 of the multiple positioning pieces 71 located on the downstream side of the conveying direction, i.e., the lower ends, are adjusted to be located lower than the upper surface position of the core components directly placed on the conveyor belt 60, specifically, the lowermost fixed core component 10. When the abutting surfaces 72 are adjusted to such a height, the fixed core components 10 and the non-fixed core components 20 placed on the conveyor belt 60 can be reliably positioned. It should be noted that the lower ends of the positioning pieces 71 can also be arranged lower than the upper surface of the conveyor belt 60. In this case, it is preferable to narrow the width of the conveyor belt 60 to such an extent that it does not contact the positioning pieces 71 at the positioning position P5.

[0107] In order to control the above-mentioned components, the manufacturing apparatus 1 of this embodiment may further include a control device 100. The control device 100 may be, for example, Figure 3As shown by the dotted lines in FIG, the control device 100 is connected to each component in a communicable manner via wired or wireless communication. A computer including a sequencer (Programmable Logic Controller: PLC) can be used as the control device 100.

[0108] The manufacturing device 1 of the stacked body of this embodiment is configured as described above, and in particular, the locking portion 51 of the partition mechanism 50 is configured to lock the locking piece 13, so that the locking portion 51 does not come into contact with the non-locked core member 20. Therefore, the period during which the non-locked core member 20 passes through a position on the conveying path provided with the partition mechanism 50 can be used as time for moving the locking portion 51 to the locking position P1. As a result, the manufacturing device 1 of the stacked body can ensure a longer time for moving the locking portion 51 to the locking position P1 than in the past, and even if the actuator 52 and sensor 53 included in the partition mechanism 50 do not adopt devices with a fast response speed, the stacking of the core members can be performed with high precision. Therefore, the stacking of the core members can be accurately and efficiently performed without the need for special devices. In addition, the manufacturing device 1 of the stacked body can be manufactured relatively cheaply, and the maintenance frequency can also be reduced.

[0109] Furthermore, in the manufacturing device 1 described above, the locking piece 13 is shown as being composed of a protrusion protruding from the outer peripheral surface of the locking core member 10, and the locking portion 51 moves in a direction approaching or away from the center of the locking core member 10, but the present disclosure is not limited to this. For example, a portion of the outer peripheral edge of the locking core member 10 can also be used as a locking piece, and a recess can be formed in a corresponding portion of the non-locking core member 20 instead of providing the locking piece 13 on the locking core member 10. In addition, the working direction of the locking portion 51 can also be set to be along the circumferential direction of the core member instead of along the radial direction of the core member.

[0110] Furthermore, in the laminate manufacturing apparatus 1 of this embodiment, the conveyor 60 can receive the locked core members 10 and the unlocked core members 20 discharged from the extrusion tool 40. Therefore, there is essentially no need to change the conveyor 60 to account for the shapes of the locked core members 10 and the unlocked core members 20. In other words, there is no need to prepare a plurality of members (e.g., jigs) in advance for receiving the locked core members 10 and the unlocked core members 20.

[0111] Furthermore, in the manufacturing apparatus 1 described above, the locking piece is shown as a projection protruding from the outer peripheral surface of the core member 10, and the partitioning mechanism 50 is provided outside the core member conveying path. However, the locking piece 13 may also be formed on the inner peripheral surface of the core member 10. In this case, the partitioning mechanism 50 is preferably also provided on the inner peripheral surface side of the core member.

[0112] (Method for producing laminate)

[0113] Next, the method for manufacturing a laminated body according to this embodiment will be described. In the following description, an example of manufacturing a laminated body using the aforementioned laminated body manufacturing apparatus 1 is illustrated. However, the method for manufacturing a laminated body disclosed herein may also be implemented using an apparatus other than the aforementioned manufacturing apparatus 1. The method for manufacturing a laminated body according to this embodiment implemented by the laminated body manufacturing apparatus 1 may be provided in the form of a program for causing a processor of a control device 100 that controls the various components of the laminated body manufacturing apparatus 1 to execute predetermined actions, or may be provided in the form of a non-transitory computer-readable recording medium storing the program.

[0114] As an example of an apparatus other than the aforementioned manufacturing apparatus 1 capable of implementing the laminate manufacturing method, one may cite an apparatus in which the partitioning mechanism 50 of the manufacturing apparatus 1 is positioned on the inner circumferential surface of the core member. In this case, the locking tabs 13 for locking the core member 10 are formed on the inner circumferential surface of the yoke 11. It should be noted that the description of the effects and the like shown below also serves as a description of the effects of the manufacturing apparatus 1 of this embodiment.

[0115] Figure 7 FIG. 8 is a flowchart showing an example of a method for manufacturing a laminate according to the first embodiment of the present disclosure. Figure 7 The method for manufacturing the laminate shown in FIG. Figure 3 FIG9 is an explanatory diagram of the operation of the main parts of the manufacturing device shown in FIG8. Figure 3 8 illustrates the conveyor belt and positioning mechanism of the manufacturing apparatus. It should be noted that, to facilitate understanding of the conveyance of the core components from the extruded part 40 to the conveyor belt 60, only the portions of the manufacturing apparatus 1 associated with this conveyance are shown, with other portions omitted. Furthermore, the left side of the figure shows a cross-section of the positioning mechanism 70, obtained by cutting through the portion including the abutment surface 72, while the right side shows a cross-section of the portion that accommodates the locking piece 13.

[0116] The manufacturing method of the laminated body of this embodiment includes at least the following steps: supplying a plurality of core members including a locking core member 10 and a non-locking core member 20 from a supply mechanism 30, wherein the locking core member 10 has locking pieces 13 at a plurality of locations on its outer peripheral surface, and the non-locking core member 20 does not have a locking piece (corresponding to step S01 described later); using an extrusion member 40 to support the locking core member 10 and the non-locking core member 20 supplied from the supply mechanism 30 from the side and convey them (corresponding to step S02 described later); using a partitioning mechanism to selectively support the core member supplied from the end portion on the downstream side of the conveying direction of the extrusion member 40 (corresponding to step S06 described later); moving a positioning mechanism 70 arranged between the partitioning mechanism 50 and the conveyor belt 60 in the conveying direction to a positioning position P5 to position the locking core member 10 and the non-locking core member 20 to be supplied to the conveyor belt 60 position (corresponding to process S03 described later); moving the locking portion 51 from the locking position P1 to the non-locking position P2 to supply a plurality of locked core components 10 and non-locking core components 20 supported by the partition mechanism 50 to the conveyor 60 (corresponding to process S04 described later); while the non-locking core component 20 passes through a position including the locking position P1, the locking portion 51 moved to the non-locking position P2 is reset to the locking position P1 (corresponding to process S06 described later); and when a specified number of locked core components 10 and non-locking core components 20 are placed on the conveyor 60, the positioning mechanism 70 is moved to the positioning release position P6 (corresponding to process S09 described later), and the conveyor 60 is operated to transport the specified number of locked core components 10 and non-locking core components 20 placed on the conveyor in the conveying direction of the conveyor (corresponding to process S10 described later).

[0117] The method for manufacturing the laminated body according to this embodiment will be described in more detail. In this manufacturing method, a punching operation using the punch 32 and the die 31 is first initiated, and the supply of the locking core member 10 and the non-locking core member 20 to the extrusion 40 is initiated (step S01). This punching operation can be performed by lowering the punch 32 relative to the strip steel plate 2 being fed in one direction, such as the left-right direction, at a predetermined timing. The locking core member 10 and the non-locking core member 20 formed by this punching operation are pressed by the punch 32 toward the bottom of the die 31, and are then pressed into the extrusion 40 from the upper end of the extrusion 40 connected to the die 31.

[0118] Furthermore, in this embodiment, each time a core element group G consisting of four core elements is discharged from the extruder 40, the operation of the separator 50 and the conveyor 60 are performed. In this regard, with respect to the locking core elements 10 and non-locking core elements 20 punched out in step S01, it is preferable to set one or more core elements on the downstream side of the plurality (four in FIG. 8 ) of core elements constituting the core element group G as the locking core elements 10, and the remaining core elements on the upstream side as the non-locking core elements 20. In other words, it is preferable to set at least the first core element punched out of the plurality of core elements constituting the core element group G as the locking core element 10, and to set the remaining core elements as the non-locking core elements 20. This is because the core element located farthest downstream of the core element group G needs to be supported when the separator 50 temporarily stops the supply of the core elements to the conveyor 60.

[0119] At least a portion of the outer circumference of the locking core member 10 and the non-locking core member 20 pressed into the extrusion 40 is supported from the side by the inner circumference 41 of the extrusion 40. In addition, the locking core member 10 and the non-locking core member 20 supported from the side are conveyed downward in a stacked state in the extrusion 40 (process S02). The conveying of the core members by the extrusion 40 can also be performed as follows: a new core member is input from the supply mechanism 30 to the upper end of the extrusion 40, whereby the core member presses down the other core members that were previously supplied from the supply mechanism 30 and held in the extrusion 40. Therefore, the core members held in the extrusion 40 maintain a stacked state and are conveyed along the conveying direction. The actions shown in the above-mentioned processes S01 and S02 can be linked with the action of the starting punch 32 and start substantially at the same time.

[0120] In this embodiment, the example is shown in which the locking core members 10 and the non-locking core members 20 are punched out alternately in pairs, thereby feeding the locking core members 10 and the non-locking core members 20 alternately in pairs within the extrusion 40. In this regard, one core member group G is composed of two locking core members 10 and two non-locking core members 20 stacked in this order from the downstream side.

[0121] When the extrusion piece 40 starts to convey the locking core member 10 and the non-locking core member 20, then, as shown in FIG. Figure 9A As shown, the positioning piece 71 is moved to the positioning position P5 to position the locked core member 10 and the non-locked core member 20 output from the extrusion member 40 (step S03). It should be noted that the initial movement of the positioning piece 71 to the positioning position P5 may be before this.

[0122] When the extrusion piece 40 starts conveying the core components and a predetermined time has passed, the core components are sequentially conveyed from the lower end of the extrusion piece 40 toward the conveyor 60. When the conveying of the core components starts, the actuator 52 of the partition mechanism 50 is actuated to move the locking portion 51 to the non-locking position P2 (step S04). Figure 8A As shown, in the initial state of the manufacturing device 1, when the locking portion 51 is in the non-locking position P2, the step S04 can be skipped. In addition, when the holding mechanism 55 is in the locking position P3 at this time point, it is also better to move the holding mechanism 55 to the non-locking position P4 in advance.

[0123] When the locking portion 51 is at the non-locking position P2, there is no locking portion 51 on the conveying path of the core member. Therefore, the core members constituting one core member group G output from the extruder 40 at this timing move downward in sequence. Figure 9B As shown, each core member is placed and stacked on the conveyor 60. At this time, the locked core member 10 and the non-locked core member 20 output from the extrusion member 40 are guided to the desired position on the conveyor 60 by the positioning piece 71 provided at the positioning position P5. Figure 8B As shown, the height of the lower end of the positioning piece 71 is adjusted to be located at a distance X below the upper surface of the core member directly placed on the conveyor 60, that is, the upper surface of the locking core member 10 located on the downstream side of the core member group G. Therefore, the positioning mechanism 70 can reliably position all the core members placed on the conveyor 60.

[0124] The movement of the locked core member 10 and the non-locked core member 20 output from the extrusion 40 is preferably monitored by a sensor 53. The sensor 53 can be disposed at a position in the vertical direction including the locking position P1 where the locking portion 51 of the partition mechanism 50 locks the locking piece 13 of the locked core member 10 (hereinafter referred to as the "core member support position"). In this way, the sensor 53 can sense the passage of the locked core member 10 through the core member support position.

[0125] When the above-mentioned sensor 53 or the like senses the passage of the locked core member 10 in the core member group G (step S05), Figure 8B As shown, the actuator 52 of the partition mechanism 50 is operated to start the movement of the locking portion 51 to the locking position P1 (step S06). Here, the locking core member 10 passing through the core member support position means that the locking core member located at the upstream end of one core member group G (at the Figure 8B The second locked core member from the bottom) 10 passes through the core member support position.

[0126] The detection method of the passage of the locked core member 10 through the core member support position is not limited to the above method. For example, it is also possible to detect the change of the core member passing through the core member support position from the locked core member 10 to the non-locked core member 20, or to perform the above detection instead by sensing the passage of the locked core member 10 through the core member support position based on the timing determined by calculation taking into account the supply quantity and supply time of the core member from the supply mechanism 30 instead of using a sensor. Compared with the case of directly detecting the passage of the above-mentioned locked core member 10 by the sensor 53, such an alternative detection method tends to have a generally lower detection accuracy. However, in the manufacturing method of the laminated body of the present embodiment, as described later, the time for the partition mechanism 50 to move from the non-locked position P2 to the locked position P1 will be ensured to be longer, so the above-mentioned alternative detection method can also be adopted.

[0127] The movement of the locking portion 51 to the locking position P1 in step S06 may be completed from the time the most upstream locked core member 10 in one core member group G passes through the core member support position to the time the most downstream locked core member 10 of another core member group G transported after the one core member group G reaches the core member support position. Figure 8B As shown, this period includes the period during which two non-locked core members 20 pass through the core member support position, and the non-locked core member 20 does not have the locking piece 13. Furthermore, the locking position P1 of the locking portion 51 is set on the moving path of the locking piece 13. Therefore, even if the locking portion 51 is at the locking position P1 when the non-locked core member 20 passes through the core member support position, the locking portion 51 will not hinder the transportation of the non-locked core member 20.

[0128] When the locking portion 51 is completely moved to the locking position P1, then, as shown in FIG. Figure 8C As shown, the holding mechanism 55 starts to move from the non-locking position P4 to the locking position P3 (step S07). The timing of the movement of the holding mechanism 55 to the locking position P3 can be set to be immediately after the locking portion 51 locks the locking core member 10, or after the multiple locking core members 10 (or multiple locking core members 10 and non-locking core members 20 depending on the situation) are supported by the locking portion 51.

[0129] When the locking portion 51 and the holding mechanism 55 have completed supporting the core element group G, it is detected whether the number of locked core elements 10 and non-locked core elements 20 placed on the conveyor 60 has reached a predetermined number. If the predetermined number has not been reached ("No" in step S08), the process returns to step S04 and a new core element group G is supplied to the conveyor 60. Here, the predetermined number of core elements refers to an arbitrary number of core elements set in advance by the user or the like.

[0130] On the other hand, when the number of the locked core members 10 and the non-locked core members 20 placed on the conveyor 60 reaches a predetermined number ("Yes" in step S08), these core members are transported as a stack to a predetermined location, for example, a location where subsequent steps are to be performed. Specifically, first, as shown in FIG. Figure 8C and Figure 9C As shown, the positioning piece 71 is operated and moved to the positioning release position P6, which is a position where it does not contact the stacked body being transported by the conveyor 60 (step S09). Next, the conveyor 60 is operated to transport a predetermined number of core elements placed on the conveyor 60 to a predetermined position (step S10). When this transport operation is completed, the process returns to step S03, where the positioning piece 71 is again moved to the positioning position P5, and then a new core element group G is supplied to the conveyor 60.

[0131] As described above, according to the method for manufacturing a laminated body of this embodiment, the supply of the core components is controlled by bringing the locking portion 51 of the partitioning mechanism 50 into contact with the locking piece 13. Therefore, the time required to move the locking portion 51 can be extended compared to the past. Thus, the components of the partitioning mechanism 50 and the like do not need to use special devices, specifically devices with a fast response speed. Furthermore, each locking portion 51 can be reliably moved to the locking position P1, and the locking of the locking portion 51 and the locking piece 13 can be stably performed.

[0132] Furthermore, according to the method for manufacturing a laminated body of this embodiment, the plurality of core members discharged from the extrusion 40 are placed at desired positions on the conveyor 60 by the positioning mechanism 70, thereby eliminating the need for separate positioning of the core members. Furthermore, since the conveyor 60 can be used to transport a predetermined number of core members, there is no need to prepare multiple jigs for stacking core members of various shapes, as was conventionally done.

[0133] Alternatively, in the above embodiment, for one core member group G, the example is shown in which the two core members on the downstream side are set as the locking core members 10 and the two core members on the upstream side are set as the non-locking core members 20. However, it is also possible to set only one core member on the downstream side as the locking core member 10 and the remaining three core members as the non-locking core members 20. In this way, by increasing the number of non-locking core members 20 constituting the core member group G, it is possible to ensure a longer time for moving the partition mechanism 50.

[0134] Alternatively, in the above embodiment, an example is given of a process (process S07) of moving the holding mechanism 55 to the locking position, but this process may be replaced by a process of increasing the supporting force of the locking portion 51 on each core member. Specifically, a process may be adopted in which the locking portion 51 is moved to a position (corresponding to the holding position) where it not only locks the locking piece 13 but also locks at least a portion of the outer periphery of the core member 10. Figure 5 When the action is performed in the direction indicated by the arrow A3 in FIG, if the position after the locking portion 51 is moved in the direction closer to the center of the locking core component 10 than the locking position P1 is set as the holding position, the supporting force of the locking portion 51 on the core component can be increased without using the above-mentioned holding mechanism 55, thereby achieving stable support of each core component.

[0135] <Second embodiment>

[0136] While the first embodiment described above uses a separator 50 to control the supply of each core member to the conveyor 60, the present disclosure is not limited to this configuration. Therefore, the following describes a second embodiment of the present disclosure, which describes an apparatus and method for manufacturing a laminated body that does not use a separator 50.

[0137] (Laminate Manufacturing Apparatus)

[0138] The manufacturing apparatus 1A of this embodiment can include the same configuration as the manufacturing apparatus 1 of the first embodiment, except that it does not include components such as the partitioning mechanism 50 and that the structure of the extrusion member is different. Therefore, the following description will focus on the configuration that differs from the manufacturing apparatus 1 of the first embodiment, with portions having the same configuration as the manufacturing apparatus 1 of the first embodiment being denoted by the same reference numerals as those used in the description of the first embodiment, and their description will be omitted.

[0139] Figure 10 : is a schematic explanatory diagram showing an example of a manufacturing apparatus for a laminated body according to a second embodiment of the present disclosure. Figure 10 So with Figure 3 The corresponding method is described in the figure. Figure 10 As shown, the manufacturing apparatus 1A of the laminated body of this embodiment includes: a second extruder 80, which can Figure 1 and Figure 2The illustrated locked core members 10 and non-locked core members 20 are conveyed downward; the supply mechanism 30 is located above the second extrusion member 80 and can selectively supply each core member to the second extrusion member 80; the conveyor belt 60 can be located below the second extrusion member 80 and can receive each core member supplied from the end portion on the downstream side of the conveying direction of the second extrusion member 80; and the positioning mechanism 70 positions the core member to be supplied to the conveyor belt 60. It should be noted that the shape of the core members stacked by the manufacturing device 1A of the laminated body of this embodiment is the same as that of the manufacturing device 1 of the laminated body of the first embodiment and is not limited to Figure 1 and Figure 2 The shape shown.

[0140] The second extrusion 80 can be formed of a substantially cylindrical member that conveys the locked core member 10 and the unlocked core member 20, which are punched and formed by the feed mechanism 30 including the die 31 and the punch 32 and pressed from below the die 31, to the conveyor 60. Furthermore, the second extrusion 80 includes an upstream portion 81 located upstream in the direction of conveyance of the core members and laterally supporting both the locked core member 10 and the unlocked core member 20 as they pass through the second extrusion 80; and a downstream portion 82 located downstream in the direction of conveyance of the core members and laterally supporting the locking tabs 13 that lock the core member 10 as it passes through the second extrusion 80.

[0141] The upstream portion 81 of the extrusion member may have the same structure as the extrusion member 40 of the first embodiment. Figure 4 The inner circumference 41 of the extruded parts 40 shown is of the same shape.

[0142] Figure 11 It is along Figure 10 A schematic cross-sectional view obtained by cutting along the G-G line of FIG. Figure 11 As shown, the downstream portion 82 of the extrusion member may be provided with a first locking portion 83 on its inner peripheral surface at a position facing the locking piece 13 that locks the core member 10 , which abuts against the locking piece 13 from the side to support the locked core member 10 .

[0143] A point of particular note here is that, in the downstream portion 82 of the extrusion, neither the locking core member 10 nor the non-locking core member 20 is supported in the portion of the inner circumferential surface thereof other than the portion where the first locking portion 83 is formed. In the laminate manufacturing apparatus 1A of this embodiment, a gap 84 is formed between the inner circumferential surface of the downstream portion 82 of the extrusion, other than the portion where the first locking portion 83 is formed, and the outer circumferential surface of each core member. It should be noted that the shape of the inner circumferential surface of the downstream portion 82 of the extrusion can be appropriately modified to match the shape of the locking core member 10 and the non-locking core member 20 to be transported.

[0144] The laminated body manufacturing apparatus 1A of this embodiment includes the aforementioned second extrusion 80. Thus, in the downstream portion 82 of the extrusion, only the locking core members 10 are conveyed while supported. The non-locking core members 20 are not supported laterally by the second extrusion 80, but are moved along the conveyance path while resting on the upper surfaces of the downstream locking core members 10. Furthermore, the non-locking core members 20 are ejected from the second extrusion 80 simultaneously with the downstream locking core members 10 being ejected from the lower end of the second extrusion 80.

[0145] As described above, if the unlatched core member 20 and the latched core member 10 are simultaneously discharged, the time interval between the unlatched core member 20 and the latched core member 10 being discharged from the lower end of the second extrusion piece 80 becomes longer. Therefore, the conveyor 60 can be used for transportation at this timing, eliminating the need to stop the device for transportation or use a special device for controlling the timing of core member supply, thereby enabling continuous and accurate lamination of core members.

[0146] Furthermore, in the laminate manufacturing apparatus 1A of this embodiment, similarly to the laminate manufacturing apparatus 1 of the first embodiment, the conveyor 60 can receive the locked core members 10 and the unlocked core members 20 output from the second extrusion tool 80. Therefore, there is essentially no need to change the conveyor 60 to account for the shapes of the locked core members 10 and the unlocked core members 20. In other words, there is no need to prepare a plurality of members (e.g., jigs) in advance for receiving the locked core members 10 and the unlocked core members 20.

[0147] (Method for producing laminate)

[0148] Next, the method for manufacturing a laminated body according to this embodiment will be described. The following description uses the aforementioned laminated body manufacturing apparatus 1A as an example for manufacturing a laminated body. However, the method for manufacturing a laminated body disclosed herein can also be implemented using apparatuses other than the laminated body manufacturing apparatus 1A. It should be noted that the description of the effects and the like shown below also serves as a description of the effects of the manufacturing apparatus 1A according to this embodiment.

[0149] Figure 12 FIG13 is a flowchart showing an example of a method for manufacturing a laminate according to a second embodiment of the present disclosure. Figure 12 The method for manufacturing the laminate shown in FIG. Figure 10 FIG14 is an explanatory diagram of the operation of the main part of the manufacturing device shown in FIG13. Figure 1013 illustrates the conveyor belt and positioning mechanism of the manufacturing apparatus. It should be noted that, in order to facilitate understanding of the conveyance of the core members from the second extrusion 80 to the conveyor belt 60, only the portions of the manufacturing apparatus 1A related to this conveyance are shown, and illustration of other portions is omitted.

[0150] The manufacturing method of the laminated body of this embodiment includes at least the following steps: supplying a plurality of core members including a locking core member 10 and a non-locking core member 20 to an extrusion part (corresponding to step S21 described later); moving the positioning mechanism 70 to the positioning position P5 to position the core members to be supplied from the lower end of the second extrusion part 80 to the conveyor 60 (corresponding to step S23 described later); supplying the locking core member 10 and the non-locking core member 20 from the lower end of the second extrusion part 80 to the conveyor 60; when a specified number of core members are placed on the conveyor 60, moving the positioning mechanism 70 to the positioning release position P6, and conveying the specified number of core members placed on the conveyor 60 in a direction intersecting the conveying direction (corresponding to steps S25 and S26 described later).

[0151] The method for manufacturing the laminated body according to this embodiment will be described in more detail. In this method, a punching operation using the punch 32 and the die 31 is first initiated, and the supply of the locking core member 10 and the non-locking core member 20 to the second extrusion 80 is initiated (step S21). This punching operation can be performed by lowering the punch 32 relative to the strip steel plate 2 being fed in one direction, such as the left-right direction, at a predetermined timing. The locking core member 10 and the non-locking core member 20 formed by this punching operation are pressed by the punch 32, moving downward from the die 31 and being pressed into the second extrusion 80 from the upper end portion of the second extrusion 80 connected to the die 31.

[0152] Furthermore, in this embodiment, each time a core element group G consisting of four core elements is ejected from the second extrusion block 80, it is transported by the conveyor 60. In this regard, in step S21, of the punched locking core elements 10 and non-locking core elements 20, one or more core elements located downstream of the plurality (four in FIG. 13 ) of core elements constituting the core element group G are preferably designated as locking core elements 10, while the remaining core elements located upstream are designated as non-locking core elements 20. This embodiment illustrates a case where the locking core elements 10 and non-locking core elements 20 are punched alternately in pairs, thereby conveying the locking core elements 10 and non-locking core elements 20 alternately within the second extrusion block 80.

[0153] At least a portion of the outer circumference of the locking core members 10 and the non-locking core members 20 pressed into the second extrusion 80 is laterally supported by the inner circumference of the second extrusion 80, particularly the inner circumference of the upstream portion 81 of the extrusion. Furthermore, the laterally supported locking core members 10 and the non-locking core members 20 are transported downward in a stacked state within the second extrusion 80 (step S22). With respect to the locking core members 10 and the non-locking core members 20 pressed into the second extrusion 80, in the upstream portion 81 of the extrusion, both the locking core members 10 and the non-locking core members 20 are transported along the transport direction while maintaining their laterally supported and stacked state.

[0154] When the second extrusion member 80 starts to convey the locked core member 10 and the non-locked core member 20, then Figure 14A As shown, the positioning piece 71 is moved to the positioning position P5 to position the locked core member 10 and the non-locked core member 20 output from the second extrusion member 80 (step S23). It should be noted that the initial movement of the positioning piece 71 to the positioning position P5 may also be before this.

[0155] When the core members in the second extrusion 80 are conveyed and a part of the core members reaches the downstream portion 82 of the extrusion, the locking core member 10 among the core members is in contact with the locking portion 83 by the locking piece 13, thereby maintaining the support from the side. On the other hand, the support from the side of the non-locking core member 20 is released, and the non-locking core member 20 is supported by the upper surface of the locking core member 10 located on the downstream side (see Figure 13A ).

[0156] As the second extrusion 80 further conveys the core members, the most downstream-located locking core member 10 among the core members constituting one core member group G is first discharged from the lower end portion of the second extrusion 80. Subsequently, the locking core member 10 conveyed within the downstream portion 82 of the extrusion in a stacked state with its lower surface abutting against the upper surface of the most downstream-located locking core member 10 (hereinafter, for ease of explanation, this locking core member 10 will be temporarily referred to as the "second locking core member 10") is discharged from the lower end portion of the second extrusion 80.

[0157] Here, the second locking core member 10 has two non-locking core members 20, included in the same core member group G, placed on its upper surface. The non-locking core members 20 are not supported from the side by the downstream portion 82 of the extrusion. Therefore, when the second locking core member 10 is ejected from the lower end of the second extrusion 80, the two non-locking core members 20 are also ejected from the lower end of the second extrusion 80. Furthermore, at this time, the locking core member 10 stacked upstream of the two ejected non-locking core members 20 is transported at a position away from the lower end of the second extrusion 80.

[0158] like Figure 13B and Figure 14B As shown, when the two non-locking core members 20 supported by the second locking core member 10 and its upper surface are placed on the conveyor 60, the number of the locking core members 10 and the non-locking core members 20 placed on the conveyor 60 is sensed. If the number of the locking core members 10 and the non-locking core members 20 on the conveyor 60 does not reach the specified number ("No" in process S24), the process waits until the specified number is reached. On the other hand, when it is sensed that the specified number has been reached ("Yes" in process S24), these core members are transported as a stack to a specified position, such as a position where a subsequent process is to be performed. Here, at the timing of transporting the stack, as described above, the locking core member 10 that is then transported to the conveyor 60 is transported at a position away from the lower end of the second extrusion 80. Therefore, a longer time is ensured before the locking core member 10 being transported in the second extrusion 80 is output from the lower end of the second extrusion 80. Therefore, there is substantially no need to temporarily stop the apparatus while conveying the stacked body.

[0159] The conveyor belt 60 is used to transport the stacked body. Figure 13C and Figure 14C As shown, the positioning piece 71 is moved to the positioning release position P6 (step S25). Next, the conveyor 60 is operated to transport the predetermined number of core members placed on the conveyor 60 to a predetermined position (step S26). Then, when this transport operation is completed, the process returns to step S23, and after the positioning piece 71 is moved to the positioning position P5 again, a new core member group G is supplied to the conveyor 60. If the above step S23 is carried out before the new core member is discharged from the lower end of the second extrusion piece 80, the laminated body can be continuously manufactured without stopping the apparatus.

[0160] As described above, according to the method for manufacturing a laminated body of this embodiment, the timing of each core member being discharged from the lower end of the second extrusion 80 can be adjusted simply by designing a portion of the inner circumferential surface of the second extrusion 80. Consequently, laminated bodies can be manufactured continuously with a simple structure. Furthermore, by configuring the downstream portion 82 of the extrusion to support and retain only the core members 10, the time from each discharge of the core member group G to the next discharge is ensured to be long, thereby enabling the conveyor 60 to transport the laminated body without stopping the device.

[0161] Furthermore, according to the method for manufacturing a laminated body of this embodiment, the plurality of core members discharged from the second extrusion tool 80 are placed at desired positions on the conveyor 60 by the positioning mechanism 70, thereby eliminating the need for separate positioning of the core members. Furthermore, since a predetermined number of core members can be transported using the conveyor 60, there is no need to prepare multiple jigs for stacking core members of various shapes, as was previously the case.

[0162] Furthermore, in the manufacturing method of the laminated body of the present embodiment, the locking core members 10 and the non-locking core members 20 output from the second extrusion piece 80 are directly supplied to the conveyor 60. Here, the conveyor 60 transports the laminated body to the subsequent process. Therefore, for example, in the case where an abnormality occurs in the subsequent process and it is desired to temporarily stop the supply of the laminated body to the subsequent process, the conveyor 60 may be stopped or driven even in the middle of the above-mentioned manufacturing method. In order to cope with such unexpected driving or stopping of the conveyor 60, the manufacturing device and manufacturing method of the laminated body of the present embodiment are configured to be able to temporarily hold the locking core members 10 and the non-locking core members 20 output from the second extrusion piece 80. The following describes a structure for temporarily holding the locking core members 10 and the non-locking core members 20 output from the second extrusion piece 80 and a process for holding them.

[0163] 15 is an explanatory diagram showing a state where the positioning mechanism is set to a holding position in the manufacturing apparatus for a laminated body according to the second embodiment of the present disclosure, Figure 15A Show that Figure 10 The positioning piece of the manufacturing device shown is set to a state of maintaining the position, Figure 15B Show Figure 15A In the state shown Figure 10The state of the conveyor belt and positioning mechanism of the manufacturing apparatus shown. The manufacturing apparatus 1A of the laminated body of this embodiment may also include a holding portion, which is disposed between the downstream end of the second extrusion member 80 in the conveying direction and the conveyor belt 60, and is capable of holding the core member to be supplied to the conveyor belt 60 before being placed on the conveyor belt 60. Specifically, as shown in FIG15 , the holding portion of the manufacturing apparatus 1A of the laminated body of this embodiment can be composed of a holding surface 74 formed on the upstream side of the plurality of positioning pieces 71 in the conveying direction.

[0164] The holding surface 74 can be formed of a flat surface formed on the upper portion of the plurality of positioning pieces 71. Furthermore, if the plurality of positioning pieces 71 are moved closer to the center of the conveying path than the positioning position P5, the holding surface 74 can be moved to the holding position P7, which is a position at which the core member output from the second extrusion piece 80 can be held before it reaches the conveyor 60. When the holding surface 74 is at the holding position P7, as shown in FIG. Figure 15A As shown, the locked core members 10 and the unlocked core members 20 discharged from the second extrusion tool 80 are placed on the holding surface 74 before reaching the conveyor 60. This allows the conveyor 60 to be freely moved during a series of processes for manufacturing a laminated body.

[0165] In connection with this, the method for manufacturing a laminated body according to the present embodiment may include the step of moving the positioning pieces 71 constituting the positioning mechanism 70 to a holding position P7, where the holding surface 74 thereof is capable of holding the core member output from the second extrusion member 80. The gap W1 between the positioning pieces 71 at the holding position P7 may be smaller than the gap W2 between the positioning pieces at the positioning position P5.

[0166] In the above embodiment, the holding portion is constituted by a part of the positioning mechanism 70, but the holding portion and the positioning mechanism 70 may be constituted by other members. In this case, the holding portion may be constituted by a member having the same structure as the holding mechanism 55 of the laminated body manufacturing apparatus 1 of the first embodiment, for example.

[0167] In the aforementioned laminate manufacturing apparatus and method, examples of laminate manufacturing using a locking core member 10 and a non-locking core member 20 formed from a single electromagnetic steel sheet as core members are described. However, the shape of the core members is not limited to this. Therefore, the following briefly describes another example of a core member that can be used in the aforementioned laminate manufacturing apparatus and method.

[0168] 16 is a diagram showing another example of a locking core member supplied to the manufacturing apparatus of the laminated body according to each embodiment of the present disclosure, Figure 16A It is a top view. Figure 16B Therefore Figure 16A A cross-sectional view taken along line BB of FIG. A locking core member 10A, another example of a core member, is similar to the above-described locking core member 10 in that it includes an annular yoke 11, teeth 12 provided on the inner periphery of the yoke 11, and locking pieces 13 protruding outward from the outer periphery of the yoke 11, as shown in FIG.

[0169] On the other hand, Figure 16B As shown, the locking core member 10A can be composed of a block formed by bonding multiple (e.g., three) plate-shaped core pieces 14. The core pieces 14 can be composed of thin electromagnetic steel sheets. It should be noted that the number of core pieces 14 constituting the block is not particularly limited and can be appropriately adjusted, for example, from a few to dozens of core pieces.

[0170] In addition, in order to join the multiple chips 14 constituting the block together, a rivet 15 or a hole 16 may be formed at an appropriate position of the yoke 11 of the chip 14. When the chips 14 are stacked on each other, the chips 14 can be joined together by engaging with each other through the rivet 15 or the hole 16. It should be noted that the chip 14 arranged at the bottom of the multiple chips 14 constituting the block is provided with a hole 16 without a protrusion on the lower surface, and it is better to provide a rivet 15 on the other chips 14. In addition, in this embodiment, the case where the rivet 15 is used as the joining structure between the chips 14 is shown as an example, but other joining methods may be used instead, such as a method of joining the chips together by applying an adhesive on the joining surface.

[0171] Furthermore, although all of the plurality of core pieces 14 constituting the locking core member 10 shown in FIG16 are provided with projections constituting the locking piece 13, such projections only need to be provided on the core piece 14 located at least at the bottom of the locking core member 10 among the plurality of core pieces 14. In other words, projections constituting the locking piece 13 may not be provided on the core piece 14 located above the bottom of the locking core member 10 formed of a block. For example, a core piece having the same structure as the core piece 24 constituting the non-locking core member 20 described later may be used.

[0172] 17 is a diagram showing another example of a non-locking core member supplied to the manufacturing apparatus of the laminated body according to each embodiment of the present disclosure, Figure 17A It is a top view. Figure 17B Therefore Figure 17A The cross-sectional view obtained by cutting along the C-C line. Figure 17AAs shown, a non-locking core member 20A, another example of a core member, is similar to the non-locking core member 20 described above in that it includes an annular yoke 21 and teeth 22 provided on the inner circumferential surface of the yoke 21. The size, arrangement, and number of the yoke 21 and teeth 22 of the non-locking core member 20A can be set to match the size, arrangement, and number of the yoke 11 and teeth 12 of the locking core member 10A.

[0173] In addition, the non-locking core component 20A can also be composed of a block formed by joining multiple (for example, three) thin plate-shaped chips 24 with a specified wall thickness, similar to the above-mentioned locking core component 10A. Therefore, a rivet portion 25 or a hole portion 26 for joining the chips 24 to each other can also be formed on the chip 24.
