The present invention has been devised in consideration of these points, and aims to provide an insulating member insertion device that can automate the task of inserting insulating members into an insulating member insertion space formed in a stator. [Means for solving the problem]

[0005] The insulating member insertion device of the present invention has a plurality of insulating members extending in an axial direction at positions spaced apart in a circumferential direction. Multiple This can be used when inserting an insulating member into a stator in which an insulating member insertion space is formed. The insulating member can be made of various materials.

The insulating member insertion space of the stator is formed in various shapes. The present invention includes a conveying device that conveys the insulating member, a stator holding device that holds the stator, and a pushing device that pushes out the conveyed member. The conveying device has a conveying member that is movable between a standby position and a push-out position and conveys the insulating member from the standby position to the push-out position. As the conveying member, conveying members of various configurations that can convey the insulating member can be used. The stator holding device is capable of holding the stator and holds the stator. Rotate the stator around the stator centerline, The insulating member insertion spaces of the stator are arranged in positions facing the insulating members transported to the extrusion position. Sequential Configured to be deployable There are. The pushing-out device has a pushing-out member. The pushing-out member pushes the insulating member conveyed by the conveying member in a state where the conveying member is moved to the pushing-out position. Among the multiple insulating member insertion spaces of the stator held by the stator holding device, At a position opposite to the insulating material conveyed to the extrusion position The insulating member insertion space side where the insulating member is arranged As the pushing member, pushing members of various configurations capable of pushing out the conveyed member conveyed to the pushing position can be used. According to the present invention, the operation of inserting the insulating member into the insulating member insertion space of the stator can be automated, which allows the stator to be manufactured simply and in a short time. In another embodiment of the present invention, the stator holding device has an insulating member guide portion that guides the insulating member extruded by the extrusion member into the insulating member insertion space of the stator. As the insulating member guide portion, an insulating member guide portion having an appropriate configuration according to the shape of the insulating member, etc. is used. In this embodiment, the insulating member pushed out by the push-out member can be reliably inserted into the insulating member insertion space of the stator. In another embodiment of the present invention, an insulating member manufacturing apparatus is provided for manufacturing an insulating member, and the insulating member manufactured by the insulating member manufacturing apparatus is fed to a conveying member. As the insulating member manufacturing apparatus, an insulating member manufacturing apparatus having an appropriate configuration according to the shape of the insulating member, etc., may be used. As a method for sending the insulating member manufactured by the insulating member manufacturing apparatus to the conveying member, a method of sending the insulating member directly from the insulating member manufacturing apparatus or a method of sending the insulating member via another member may be used. In this embodiment, the operations from manufacturing the insulating member to inserting the insulating member into the insulating member insertion space of the stator can be automated, thereby enabling the stator to be manufactured in a shorter time. In another embodiment of the present invention, the conveying member has an insulating member insertion hole that is open at both ends and into which the insulating member can be inserted, and a push-out member insertion hole that is open at both ends and into which the push-out member can be inserted, and is configured so that the insulating member inserted in the insulating member insertion hole is pushed out by the push-out member moving within the push-out member insertion hole along the extension direction of the push-out member insertion hole. In this embodiment, the push-out device that pushes out the insulating member transported to the push-out position can be configured simply. In another embodiment of the present invention, the push-out member insertion hole is formed at a position at least partially overlapping with the insulating member insertion hole so as to extend parallel (including "approximately parallel") to the extending direction of the insulating member insertion hole. In this embodiment, the extrusion device can be configured more simply. In a different embodiment of the present invention, the insulating member is formed by folding a first edge portion including a first edge, a second edge portion including a second edge, and a first central portion and a second central portion provided between the first edge portion and the second edge portion so that the cross section has a V-shape.

The insulating member is inserted in a folded state into the insulating member insertion hole of the conveying member, and is held in the conveying member insertion hole by elastic restoring force. Also, the insulating member is pushed out of the insulating member insertion hole in a T-shaped state, and can be easily inserted into the insulating member insertion space of the stator. Furthermore, the insulating member is held in the insulating member insertion space of the stator by elastic restoring force. In this embodiment, the insulating member, whose cross section is bent into a V shape, can be easily inserted into the insulating member insertion space of the stator. In another aspect of the invention, a folding device is provided. The folding device has a folding member that folds an insulating member having a V-shaped cross section into a shape having a T-shaped cross section. The folding device is configured so that the insulating member folded by the folding member to have a T-shaped cross section is sent to a conveying member. The folding member may be of various configurations capable of folding an insulating member having a V-shaped cross section into a shape having a T-shaped cross section. For example, a folding member having both ends open and an insulating member insertion hole into which an insulating member can be inserted may be used. The insulating member insertion hole is formed so that the insulating member can be folded into a shape having a T-shaped cross section by inserting an insulating member having a V-shaped cross section. The insulating member folded by the folding member into a shape having a T-shaped cross section can be sent to the conveying member by a method of sending it directly from the folding member or a method of sending it via another member. When sending an insulating member having a V-shaped cross section manufactured by the insulating member manufacturing apparatus to the conveying member, it is preferably configured to send it to the conveying member via a folding member. In this embodiment, it is possible to easily configure an insulating member insertion device that inserts an insulating member having a V-shaped cross section into an insulating member insertion space of a stator. In another embodiment of the present invention, the stator has a yoke extending circumferentially, a plurality of teeth extending radially inward from the yoke, a resin bobbin arranged around each of the teeth, and a stator winding wound around the resin bobbin. In addition, the insulating member insertion space of the stator is composed of a first space portion formed between the stator winding wound around a resin bobbin arranged around the tooth on one circumferential side of adjacent teeth and the stator winding wound around a resin bobbin arranged around the tooth on the other circumferential side, a second space portion formed between the resin bobbin arranged around the tooth on one circumferential side and the yoke, and a third space portion formed between the resin bobbin arranged around the tooth on the other circumferential side and the yoke. The insulating member extruded by the extrusion member is configured so that the first central portion and the second central portion are inserted into the first spatial portion of the insulating member insertion space, the first edge portion is inserted into the second spatial portion of the insulating member insertion space, and the second edge portion is inserted into the third spatial portion of the insulating member insertion space. In this embodiment, an insulating member having a V-shaped cross section can be easily inserted into an insulating member insertion space consisting of a first spatial portion formed between the stator winding wound around a resin bobbin arranged around the tooth on one circumferential side of adjacent teeth and the stator winding wound around a resin bobbin arranged around the tooth on the other circumferential side, a second spatial portion formed between the resin bobbin arranged around the tooth on one circumferential side and the yoke, and a third spatial portion formed between the resin bobbin arranged around the tooth on the other circumferential side and the yoke. In another embodiment of the present invention, the insulating member is formed in a plate shape. The insulating member insertion hole of the transport member is formed in a shape that allows a plate-shaped insulating member to be inserted therein. In this embodiment, the operation of inserting the plate-shaped insulating member into the insulating member insertion space of the stator can be automated. In another aspect of the invention, a conveying apparatus includes a first conveying member, a second conveying member, and a support member that supports the first conveying member and the second conveying member. The support member is configured to be movable between a first position in which one of the first conveying member and the second conveying member is positioned at a push-out position and the other at a standby position, and a second position in which one is positioned at the standby position and the other at the push-out position. In this embodiment, the insulating member can be more quickly inserted into the insulating member insertion space of the stator. Effect of the Invention

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, the term "axial direction" refers to the extension direction of the rotation center line P (see FIG. 1) of the rotor when the rotor is rotatably arranged relative to the stator. The rotation center line P corresponds to the "stator center line." The term "circumferential direction" refers to the circumferential direction centered on the rotation center line (stator center line) P when viewed in a cross section perpendicular to the axial direction (see FIG. 2) when the rotor is rotatably arranged relative to the stator. The term "radial direction" refers to the direction passing through the rotation center line (stator center line) P when viewed in a cross section perpendicular to the axial direction when the rotor is rotatably arranged relative to the stator. The term "radial inner peripheral side" refers to the side of the rotation center line (stator center line) P along the radial direction, and the term "radial outer peripheral side" refers to the opposite side of the rotation center line (stator center line) P along the radial direction. In addition, with respect to the resin bobbin, the terms "axial direction," "circumferential direction," and "radial direction" refer to the "axial direction," "circumferential direction," and "radial direction" when the resin bobbin is attached to the teeth of the stator core.

[0009] First, an example of a stator that constitutes a rotating machine such as an electric motor will be described with reference to FIGS. 1 to 6. FIG. Fig. 1 is a diagram showing a stator 100. Fig. 2 is a diagram showing a stator core 110. Fig. 3 is a diagram showing a resin bobbin 200. Fig. 4 is a diagram explaining the operation of mounting the resin bobbin 200 to the teeth 121 of the stator core 110. Fig. 5 is a diagram explaining the operation of inserting an insulating member 300 into an insulating member insertion space of the stator 100. Fig. 6 is a view of Fig. 5 as viewed from the VI-VI direction.

[0010] The stator 100 is composed of a stator core 110, a resin bobbin 200, a stator winding (not shown), and an insulating member 300.

[0011] The stator core 110 has stator core end faces 110A and 110B on one axial side and the other axial side, and is composed of a first core member 120 and a second core member 130 (see FIG. 2). That is, the stator core 110 is configured as a stator core with a split structure. The first core member 120 has a plurality of teeth 121 extending in the radial direction. The teeth 121 have tooth bases 122 extending in the radial direction and tooth tips 123 provided on the radially inner side of the tooth bases 122 and extending in the circumferential direction. The tooth tips 123 of the teeth 121 that are adjacent in the circumferential direction are connected by connecting portions 125. The second core member 130 has a yoke 131 extending in the circumferential direction. The yoke 131 has a yoke outer peripheral surface 132 and a yoke inner peripheral surface 133. The yoke inner peripheral surface 133 has yoke inner peripheral surface portions 133a to 133c. The yoke inner peripheral surface portion 133c forms a recess 134 into which the radially outer end of the teeth base 122 can be fitted. The yoke inner peripheral surface portions 133a and 133b connected to either side of the yoke inner peripheral surface portion 133c are inclined such that the thickness of the yoke 131 becomes thinner from the yoke inner peripheral surface portion 133c side toward the connection portion between the yoke inner peripheral surface portions 133a and 133b. A rotor insertion space is formed by teeth tip surfaces 124 on the radially inner side of teeth tip portions 123. The rotating machine is composed of a stator 100 and a rotor (not shown) rotatably arranged in a rotor insertion space.

[0012] The resin bobbin 200 is made of a resin having insulating properties, and has a first flange portion 210, a second flange portion 220, a body portion 230, and a through hole 270 (see FIG. 3). The first flange portion 210 (second flange portion 220) extends in the axial and circumferential directions, and has an outer peripheral surface 210A (220A) on the radially outer side, an inner peripheral surface 210B (220B) on the radially inner side, an end face 211 (221) on one axial side, an end face 212 (222) on the other axial side, a side surface 213 (223) on one circumferential side, and a side surface 214 (224) on the other circumferential side. The body portion 230 is provided between the first flange portion 210 and the second flange portion 220, and extends along the radial direction. Through hole 270 is formed in body portion 230 and extends along the radial direction. Through hole 270 is defined by inner wall surfaces 271 to 274, and both ends are open.

[0013] The first flange portion 210 is provided with protrusions 240, 250, and 260 that protrude radially outward from an outer circumferential surface 210A. The protrusion 240 is provided on the end face 211 side of the through hole 270, and has an outer wall surface 241 on the end face 211 side. The outer wall surface 241 is formed as an inclined surface whose distance from the outer circumferential surface 210A increases from the end face 211 side toward the through hole 270 side. The protrusion 250 is provided in an area on the side of the side surface 213, closer to the end surface 212 than the through hole 270. The protrusion 250 has an outer wall surface 251 on the side opposite to the protrusion 260. The protrusion 260 is provided in an area on the side of the side surface 214, closer to the end surface 212 than the through hole 270. The protrusion 260 has an outer wall surface 261 on the side opposite to the protrusion 250.

[0014] The first flange portion 210 is provided with recesses 280 and 290 recessed radially inward from the outer circumferential surface 210A. The recess 280 (first recess) is provided on the side surface 213 side (one circumferential side) of the through hole 270. The recess 280 is formed by a bottom surface 281, a wall surface 282 provided on the end surface 211 side (one axial side), and a wall surface 283 provided on the side surface 214 side (the other circumferential side). The recess 290 (second recess) is provided on the side surface 214 side (the other circumferential side) of the through hole 270. The recess 290 is formed by a bottom surface 291, a wall surface 292 provided on the end surface 211 side (one axial side), and a wall surface 293 provided on the side surface 213 side (one circumferential side). At least one of the recesses 280 and 290 may have a wall surface on the end face 212 side (the other axial side).

[0015] With resin bobbins 200 attached to teeth 121 and a stator winding (not shown) wound around resin bobbin 200, first core member 120 and second core member 130 are assembled together. First, the end of the tooth base 122 of the first core member 120 is inserted into the through hole 270 of the resin bobbin 200 from the second flange 220 side. At this time, the end of the tooth base 122 is guided into the through hole 270 by the radially inner guide surfaces 271a-274a of the inner wall surfaces 271-274 that form the through hole 270. The tooth base 122 is inserted such that the end of the tooth base 122 protrudes from the outer circumferential surface 210A of the first flange 210. Then, the end of the teeth base 122 protruding from the outer circumferential surface 210A of the first flange portion 210 of the resin bobbin 200 is press-fitted (or shrink-fitted or cold-fitted) into the recess 134 formed in the yoke 131 of the second core member 130.

[0016] Furthermore, the insulating member 300 is inserted (placed) in the insulating member insertion space of the stator 100 . The insulating member 300 is made of an insulating film formed from a resin having insulating properties, for example, a polyethylene terephthalate resin or a polyethylene naphthalate resin. 5, insulating member 300 is formed by folding a rectangular insulating film having first edge portion 301 to fourth edge portion 304 extending parallel to the axial direction so as to have a V-shaped cross section. That is, rectangular insulating film is divided into first edge portion 311 including edge portion 301, second edge portion 314 including edge portion 302 facing edge portion 301, and first central portion 312 and second central portion 313 between first edge portion 311 and second edge portion 314, and is folded at folding lines 321, 322, and 323 so as to have a V-shape when viewed from a direction perpendicular to the extension direction of first edge portion 301 and second edge portion 302.

[0017] 5, the insulating member insertion space of the stator 100 extends along the axial direction. The insulating member insertion space is defined by first to third spatial portions. The first space portion is formed between the stator windings wound around the resin bobbins 200 attached to the teeth 121 adjacent in the circumferential direction. The second spatial portion is formed between the resin bobbin 200 (the outer peripheral surface 210A of the first flange portion 210) attached to the tooth 121 on one circumferential side of the circumferentially adjacent teeth 121 and the yoke 131 (the yoke inner peripheral surface portion 133a). The third space portion is formed between the resin bobbin 200 (the outer peripheral surface 210A of the first flange portion 210) attached to the tooth 121 on the other circumferential side and the yoke 131 (the yoke inner peripheral surface portion 133b). The insulating member insertion space has a T-shape when viewed in a cross section perpendicular to the axial direction, i.e., the first space portion forms a vertical line of the T, the second space portion forms one horizontal line of the T, and the third space portion forms the other horizontal line of the T.

[0018] When the insulating member 300 is inserted into the insulating member insertion space, a force is applied so as to shorten the interval between the first edge portion 301 (first edge portion 311) and the second edge portion 302 (second edge portion 314), and the insulating member 300 is elastically deformed so that its cross section has a T-shape. That is, the first central portion 312 and the second central portion 313 form a vertical line of the T, the first edge portion 311 forms one horizontal line of the T, and the second edge portion 314 forms the other horizontal line of the T. Next, the insulating member 300, in an elastically deformed state, is inserted into the insulating member insertion space from the end face 211 side (one axial side) of the first flange portion 210 of the resin bobbin 200. Specifically, the first central portion 312 and the second central portion 313 of the insulating member 300 are inserted into the first space portion, the first edge portion 311 is inserted into the second space portion, and the second edge portion 314 is inserted into the third space portion. Next, with the insulating member 300 inserted in the insulating member insertion space, the force applied to the insulating member 300 is released, whereby the insulating member 300 elastically returns to its original state and is held within the insulating member insertion space. 5, first edge portion 311 of insulating member 300 is disposed in recess 290 on the other circumferential side of resin bobbin 200 attached to tooth 121 on one circumferential side, and second edge portion 314 is disposed in recess 280 on one circumferential side of resin bobbin 200 attached to tooth 121 on the other circumferential side. As a result, wall surfaces 282 and 283 of recess 280 restrict movement of insulating member 300 to one axial side and the other circumferential side, and wall surfaces 292 and 293 of recess 290 restrict movement of insulating member 300 to one axial side and one circumferential side. Conventionally, the work of inserting the insulating member 300 into the insulating member insertion space of the stator 100 has been performed manually by an operator.

[0019] Next, an embodiment of the insulating member insertion device of the present invention will be described. The insulating member insertion device of one embodiment described below is configured to automate the task of inserting insulating member 300, which is formed by bending it so that its cross section has a V-shape, into the insulating member insertion space of stator 100 (see FIG. 5).

[0020] 7 and 8 show an overall view of an insulating member insertion device 400 according to an embodiment. Note that Fig. 8 is an enlarged view of a part of Fig. 7. The insulating member inserting device 400 of the embodiment includes an insulating member supplying device 500 , a folding device 600 , a conveying device 700 , a stator holding device 800 , and a pushing device 900 . The insulating member supplying device 500 includes an insulating film supplying device 510 configured with a roll around which insulating film is wound, an insulating film feeding device 520 that feeds the insulating film, and an insulating member manufacturing device 530 that processes the insulating film to manufacture the insulating member 300. The folding apparatus 600 has a folding member 610 that folds the insulating member 300 having a V-shaped cross section, manufactured by the insulating member manufacturing apparatus 530, into a shape having a T-shaped cross section. The conveying device 700 has a conveying member 710 that conveys the insulating member 300, which is folded so as to have a T-shaped cross section, in a folded state. The conveying device 700 has a driving means that moves the conveying member 710 between a standby position that receives the insulating member manufactured by the insulating-member manufacturing apparatus and a push-out position that pushes out the conveyed insulating member. The stator holding device 800 holds the stator 100, and arranges the insulating member insertion space of the stator 100 at a position facing the insulating member 300 transported by the transport member 710. The stator holding device 800 has a holding means for holding the stator 100, and a driving means for rotating the held stator 100 about the stator center line. The push-out device 900 has a push-out member 910 that pushes out the insulating member 300, which has been transported in a folded state by the transport member 710, toward the insulating member insertion space of the stator 100. The push-out device 900 has a driving means for moving the push-out member 910. In this embodiment, insulating members 300 to be inserted into the insulating member insertion spaces of stator 100 are supplied by two lines (two systems), a first line (first system) A and a second line (second system) B. First line A has insulating film supplying device 510A, insulating film feeding device 520A, insulating member manufacturing device 530A, folding member 610A, and conveying member 710A. Second line B has insulating film supplying device 510B, insulating film feeding device 520B, insulating member manufacturing device 530B, folding member 610B, and conveying member 710B.

[0021] The insulating member manufacturing apparatuses 530A and 530B manufacture insulating members 300 that are bent so as to have a V-shaped cross section. Various known insulating material manufacturing apparatuses having various configurations can be used as the insulating material manufacturing apparatuses 530A and 530B. For example, the insulating material manufacturing apparatus disclosed in JP 2013-192362 A can be used.

[0022] Folding members 610A, 610B fold insulating member 300 manufactured by insulating member manufacturing apparatuses 530A, 530B. Folding members 610A, 610B have the same configuration. For this reason, the configuration of folding members 610A, 610B will be described with reference to folding member 610 shown in Figs. 9 to 11. Fig. 9 is a diagram showing folding member 610, Fig. 10 is a diagram showing Fig. 9 as viewed in the direction of arrow X, and Fig. 11 is a diagram showing Fig. 10 as viewed in the direction of arrows XI-XI. 9 to 11 show directions A, B, and C which are perpendicular to each other. Direction A indicates the direction in which insulating member insertion hole 611 of folding member 610, which will be described later, extends. Hereinafter, the extending direction of insulating member insertion hole 611 will be referred to as "direction A."

[0023] The folding member 610 folds the insulating member 300(A) having a V-shaped cross section and delivers an insulating member 300(B) having a T-shaped cross section. In this embodiment, the folding member 610 is open at both ends and has an insulating member insertion hole 611 into which the insulating member 300(A) can be inserted. The insulating member insertion hole 611 has an insertion opening on the side into which the insulating member 300(A) is inserted (hereinafter referred to as the "insertion side") and has an exit opening on the side opposite to the side into which the insulating member 300(A) is inserted, i.e., the side from which the insulating member 300(B) is delivered (hereinafter referred to as the "exit side"). In this embodiment, the insulating member insertion hole 611 has a cross shape when viewed in a cross section (see FIG. 10) perpendicular to direction A. In FIG. 9, the insulating member insertion hole 611 is formed by first to fourth insertion hole portions 611a to 611d extending in the cross directions (directions B and C) from the center of the insulating member insertion hole 611. The first to third insertion hole portions 611a to 611c are arranged in a T-shape. That is, the first insertion hole portion 611a forms a vertical line of the T, the second insertion hole portion 611b forms one horizontal line of the T, and the third insertion hole portion 611c forms the other horizontal line of the T. The second insertion hole portion 611b and the third insertion hole portion 611c extend in a direction intersecting at an acute angle with the extending direction of the first insertion hole portion 611a when viewed in a cross section perpendicular to the A direction. In this embodiment, the first central portion 312 and the second central portion 313 of the insulating member 300(A) are inserted into the first insertion hole portion 611a, the first edge portion 311 is inserted into the second insertion hole portion 611b, and the second edge portion 314 is inserted into the third insertion hole portion 611c. The shape of the insulating member insertion hole 611 is not limited to the shapes shown in Figures 9 to 11 as long as it allows the insulating member 300(A) having a V-shaped cross section to be folded into a shape having a T-shaped cross section.

[0024] The folding member 610 is composed of a first member 620 and a second member 630 . The first member 620 has first to sixth outer wall surfaces 621-626. The outer wall surface 622 extends along directions A and B, and has first to seventh outer wall surface portions 622a to 622g along direction B. The outer wall surface portions 622a and 622g exist on the same plane. The outer wall surface portions 622c-622e form a first insertion hole portion 611a of the insulating member insertion hole 611.

The fourth insertion hole portion 611d has the outer wall surface portion 631c as one side wall surface, the outer wall surface portion 631d as a bottom wall surface, and the outer wall surface portion 631e as the other side wall surface, and is open on the outer wall surface 631, 633, and 634 sides. Outer wall surface portion 631b extends obliquely in a direction recessed from outer wall surface portion 631a (direction C) from its connection with outer wall surface portion 631a toward its connection with outer wall surface portion 631c along direction B. Outer wall surface portion 631f extends obliquely in a direction recessed from outer wall surface portion 631g (direction C) along direction B from its connection with outer wall surface portion 631g toward its connection with outer wall surface portion 631e.

In other words, the outer wall surfaces 637b and 639b extend parallel to the A direction. The outer wall surface 637c of the first protrusion 637 extends obliquely along direction B from the connection side with outer wall surface 633 toward the connection side with outer wall surface portion 631c, in a direction recessed from outer wall surface 633, and also extends obliquely along direction C from the connection side with outer wall surface 637a toward the connection side with outer wall surface portion 631b, in a direction recessed from outer wall surface 633.

At this time, the first member 620 and the second member 630 are assembled such that a second insertion hole portion 611b of the insulating member insertion hole 611 is formed between the outer wall surface portion 622b of the first member 620 and the outer wall surface portion 631b of the second member 630, and a third insertion hole portion 611c of the insulating member insertion hole 611 is formed between the outer wall surface portion 622f of the first member 620 and the outer wall surface portion 631f of the second member 630. The second insertion hole portion 611b and the third insertion hole portion 611c extend in a direction forming an acute angle with respect to the extending direction of the first insertion hole portion 611a when viewed from a direction perpendicular to the A direction. As a result, a folding member 610 is obtained, which has an insulating member insertion hole 611 formed by first to fourth insertion hole portions 611a to 611d arranged in a cross shape and extending along the A direction. In this embodiment, a guide portion for guiding the insertion of the insulating member 300(A) into the insulating member insertion hole 611 is provided on the insertion side of the insulating member insertion hole 611.

In this embodiment, the outer wall surface portion 735e extends parallel to the A direction.

[0031] The third member 740 has first to sixth outer wall surfaces 741 to 746. The outer wall surface 741 extends along directions A and B, and has first to sixth outer wall surface portions 741a to 741f along direction B. The outer wall surface portions 741a, 741b, 741d, and 741f extend along directions A and B, and the outer wall surface portions 741c and 741e extend along directions A and C. The height of outer wall surface portion 741b from outer wall surface portion 741a extends in an inclined manner along direction B from the connection side with outer wall surface portion 741a toward the connection side with outer wall surface portion 741c in a direction recessed from outer wall surface portion 741a (direction C). Outer wall surface portion 741b has first to third portions 741b1 to 741b3 along direction A from the insertion side to the dispensing side. The outer wall surface portion 741c has first to third portions 741c1 to 741c3 along the A direction from the insertion side to the extrusion side. The first portion 741c1 and the third portion 741c3 extend parallel to the A direction. The first portion 741c1 is disposed closer to the outer wall surface portion 741a than the third portion 741c3. The second portion 741c2 is formed between the first portion 741c1 and the third portion 741c3, and extends at an angle with respect to the A direction. The first to third portions 741c1 to 741c3 of the outer wall surface portion 741c are connected to the first to third portions 741b1 to 741b3 of the outer wall surface portion 741b. The outer wall surface portions 741d and 741e are formed on a step surface connecting the outer wall surface portions 742c and 741f.

[0032] The fourth member 750 has first to sixth outer wall surfaces 751 to 756. Outer wall surface 751 extends along directions A and B, and has a first outer wall surface portion 751a and a second outer wall surface portion 751b along direction B. Outer wall surface portion 751a extends obliquely along direction B in a direction recessed from outer wall surface portion 751b (direction C) from the connection side with outer wall surface portion 751b toward the connection side with outer wall surface 755. The outer wall surface portion 751a has, along the A direction, first to third portions 751a1 to 751a3 from the insertion side toward the extrusion side. The outer wall surface 755 extends along the A direction and the C direction, and has outer wall surface portions 755a to 755d. The outer wall surface portions 755a and 755b are connected to the insertion side portion of the outer wall surface portion 755c via a stepped outer wall surface portion 755d. The outer wall surface portion 755a is disposed on the insertion side of the outer wall surface portion 755b, and the outer wall surface portions 755a and 755c extend parallel to the A direction. The outer wall surface portion 755b is formed between the outer wall surface portions 755a and 755c, and extends at an angle with respect to the A direction. The outer wall surface portions 755a to 755d are formed in the same manner as the outer wall surface portions 735a to 735d of the second member 730.

[0033] The first to fourth members 720 to 750 are assembled, for example, as follows. The first member 720 and the second member 730 are assembled so that the outer wall surface 731 and the outer wall surface portion 735c of the outer wall surface 735 of the second member 730 face the outer wall surface portions 722g and 722f of the outer wall surface 722 of the first member 720, respectively. As a result, the outer wall surface portions 722c and 722e of the first member 720 and the outer wall surface portions 735a to 735d of the second member 730 form a first insertion hole portion 711a of the insulating member insertion hole 711. In addition, the outer wall surface portion 722d of the outer wall surface 722 of the first member 720 and the outer wall surface portion 735e of the outer wall surface 735 of the second member 730 form a push-out member insertion hole 711e (described later). The third member 740 and the fourth member 750 are assembled so that an outer wall surface 752 and an outer wall surface portion 755c of the outer wall surface 755 of the fourth member 750 face outer wall surface portions 741f and 741e of the outer wall surface 741 of the third member 740. As a result, a fourth insertion hole portion 711d of the insulating member insertion hole 711 is formed by the outer wall surface portions 741c and 741d of the third member 740 and the outer wall surface portions 755a to 755d of the fourth member 750. Then, an assembly obtained by assembling the first member 720 and the second member 730 and an assembly obtained by assembling the third member 740 and the fourth member 750 are assembled so that an outer wall surface portion 741a of an outer wall surface 741 of the third member 740 faces an outer wall surface portion 722a of an outer wall surface 722 of the first member 720, and an outer wall surface portion 751b of an outer wall surface 751 of the fourth member 750 faces an outer wall surface portion 732a of an outer wall surface 732 of the second member 730. As a result, a second insertion hole portion 711b of the insulating member insertion hole 711 is formed by the outer wall surface portion 741b of the outer wall surface 741 of the third member 740 and the outer wall surface portion 722b of the outer wall surface 722 of the first member 720. Additionally, an outer wall surface portion 751a of an outer wall surface 751 of the fourth member 750 and an outer wall surface portion 732b of an outer wall surface 732 of the second member 730 form a third insertion hole portion 711c of the insulating member insertion hole 711. As a result of the above, a conveying member 710 is obtained, which has an insulating member insertion hole 711 formed by first to fourth insertion hole portions 711a to 711d that extend along direction A and are arranged in a cross shape (extending along directions B and C) when viewed in a cross section perpendicular to direction A, and an extrusion member insertion hole 711e that extends along direction A and at least partially overlaps with insulating member insertion hole 711.

[0034] Next, the operation of the transport device 700 will be described with reference to FIG. The conveying member 710 moves between a waiting position where the insulating member 300(B), folded so as to have a T-shaped cross section, is inserted into the insulating member insertion hole 711, and a pushing-out position where the insulating member 300(B) is pushed out of the insulating member insertion hole 711. In this embodiment, the conveying member 710A of the first line A and the conveying member 710B of the second line B are supported by a support member 760. The support member 760 moves between a first position and a second position. When the support member 760 moves to the first position, the conveying member 710A is disposed at the standby position Sa, and the conveying member 710B is disposed at the push-out position S. On the other hand, when the support member 760 moves to the second position, the conveying member 710A is disposed at the push-out position S, and the conveying member 710B is disposed at the standby position Sb. In this embodiment, the folded insulating members 300(B) are alternately transported to the removal position by the transport members 710A and 710B, so that the time required to insert the insulating members can be shortened.

[0035] Next, the configurations of the stator holding device 800 and the push-out device 900 will be described with reference to FIGS. First, a description will be given of the configuration of the push-out device 900. The push-out device 900 pushes out the insulating member 300(B), which has been transported in a folded state by the transport device 700, toward the insulating member insertion space of the stator 100 held by the stator holding device 800. In this embodiment, the push-out device 900 is made up of a push-out member 910, a support member 920, and a driving means (not shown). The push-out member 910 is configured of a long rod-shaped member. The push-out member 910 is formed so as to be insertable into a push-out member insertion hole 711e formed in the conveying member 710. The support member 920 movably supports the push-out member 910. In this embodiment, the support member 920 has a hole through which the push-out member 910 can be inserted. In this embodiment, the push-out member insertion hole 711e of the conveying member 710 is formed to at least partially overlap with the insulating member insertion hole 711. Therefore, by inserting the push-out member 910 into the push-out member insertion hole 711e of the conveying member 710, the insulating member 300(B) inserted into the insulating member insertion hole 711 can be pushed out from the dispensing opening. The support member 920 supports the push-out member 910 such that the push-out member 910 is disposed at a position facing the push-out member insertion hole 711e of the transport member 710 when the transport member 710 has moved to the push-out position.

[0036] The stator holding device 800 is capable of holding the stator 100 and is configured to be able to position the insulating member insertion hole of the held stator 100 in a position facing the insulating member 300 (B) transported by the transport device 700. In this embodiment, the stator holding device 800 is made up of a first member 810, a second member 820, and a driving means (not shown).

[0037] The first member 810 is configured to be rotatable about a rotation center line. The first member 810 has an inner circumferential surface 811 that forms an inner space. The inner space is formed so that a first portion 830 of a second member 820, which will be described later, can be inserted therein. The inner circumferential surface 811 is formed with at least one recess 812 into which a protrusion 835 formed on the outer periphery of the first portion 830 of the second member 820 can be inserted. In this embodiment, three recesses 812 are formed at equal intervals along the rotation direction. A gear 813 is formed on the outer periphery of the first member 810. The driving means of the stator holding device 800 applies a driving force to the gear 813 to rotate the first member 810. By appropriately selecting the pitch of the gear 813, the insulating member insertion space of the stator 100 held by the stator holding device 800 can be sequentially positioned to face the insulating member 300(B) transported by the transport device 700. As a driving means for rotating the first member 810, driving means of various configurations capable of adjusting the rotational position of the first member 810 (the rotational position of the stator 100 held by the stator holding device 800) can be used.

[0038] The second member 820 has a first portion 830 and a second portion 840 . The first part 830 has an end face 830A (an end face on the side of the conveying member 710 that has moved to the push-out position S) and an end face 830B (an end face on the opposite side of the conveying member 710 that has moved to the push-out position S), and also has a circular outer circumferential surface 831. At least one protrusion 835 that can be inserted into the recess 812 of the first member 810 is provided on the outer circumferential surface 831. In this embodiment, three protrusions 835 are provided at equal intervals along the circumferential direction. The first part 830 is fixed to the first member 810 in a state in which the protrusion 835 is inserted into the recess 812 of the first member 810. By inserting the protrusion 835 of the first part 830 into the recess 812 of the first member 810, the rotation of the first part 830 relative to the first member 810 is restricted. The second portion 840 has an outer diameter smaller than the outer diameter of the first portion 830 , and protrudes from an end surface 830 B of the first portion 830 . The second part 840 has a circular outer peripheral surface 831. The outer diameter of the second part 840 is set so that it can be inserted into the inner space of the stator core 110. The stator core 110 is arranged at a position where one of the stator core end faces 110A and 110B abuts against the end face 830B of the first part 830 in a state where the second part 840 is inserted into the inner space (a state where the stator core 110 is arranged around the second part 840). The stator core 110 is held by a fixing member 814 provided on the first member 810 (see FIG. 23). The stator 100 is mounted so that the stator core end face having an opening through which the insulating member 300(B) can be inserted into the insulating member insertion space, out of the stator core end faces 110A and 110B, abuts the end face 830B of the first portion 830.

[0039] In addition, the stator holding device 800 has a guide portion that guides the insulating member 300(B) extruded by the extrusion member 910 from the extrusion opening of the insulating member insertion hole 711 of the conveying member 710 into the insulating member insertion space of the held stator 100. The guide portion includes a first guide portion including an insulating member guide hole 832 formed on the outer periphery of the first part 830 of the second member 820, a second guide portion formed between a portion of the outer periphery 831 of the first part 830 on one circumferential side of the insulating member guide hole 832 and the inner periphery 811 of the first member 810, and a third guide portion formed between a portion of the outer periphery 831 of the first part 830 on the other circumferential side of the insulating member guide hole 832 and the inner periphery 811 of the first member 810 (see Figure 19). The insulating member 300(B) extruded by the extrusion member 910 has a first central portion 312 and a second central portion 313 guided by a first guiding portion, a first edge portion 311 guided by a second guiding portion, and a second edge portion 314 guided by a third guiding portion. The first guide portion includes a push-out member guide hole 833 formed so as to at least partially overlap with the insulating member guide hole 832. The push-out member guide hole 833 is disposed at a position facing the push-out member insertion hole 711e of the conveying member 710 that has moved to the push-out position. This allows the push-out member 910 to be moved along the push-out member insertion hole 711e of the conveying member 710 and the push-out member guide hole 833 of the first guide portion (see Figure 21), and the insulating member 300 (B) inserted into the insulating member insertion hole 711 of the conveying member 710 can be reliably inserted into the insulating member insertion space of the stator 100 via the guide portion. The first guide portion also includes a protrusion 834 formed on the tip side of the insulating member guide hole 832 of the first portion 830 of the second member 820 (see FIG. 22). The first guide portion is connected to an insulating member guide hole 832 formed on the outer periphery of the first portion 830 and includes an insulating member guide hole 842 formed on the outer periphery of the second portion 840 . A positioning mechanism is provided that defines the mounting position (position along the circumferential direction) of the stator 100 relative to the second member 820 so that the insulating member insertion space of the stator 100 faces the insulating member guide hole 832 formed in the outer periphery of the first portion 830 of the second member 820. As the positioning mechanism, positioning mechanisms of various configurations can be used.

[0040] The present invention is not limited to the configurations described in the embodiments, and various modifications, additions, and deletions are possible. Although the case where an insulating member in which the first edge portion, the second edge portion, the first central portion, and the second central portion are bent to have a V-shaped cross section is inserted into the insulating member insertion space has been described, the present invention can be used when insulating members of various shapes are inserted into the insulating member insertion space. For example, the present invention can be used when an insulating member having a cross section shape other than a V-shape or a plate-shaped insulating member is inserted. The insulating member insertion space of the stator is formed into a shape that allows the insulating member to be inserted. Although the folding member is constituted by a first member and a second member, the folding member may be constituted by an appropriate number of members (including one). Although the folding member having a cross-shaped insulating member insertion hole is used, the shape of the insulating member insertion hole of the folding member is not limited to this. Although a folding member having an insulating member insertion hole is used, the folding member may be of various configurations capable of folding the insulating member into a desired shape. Although the folding device (folding member) is provided, the folding device (folding member) may be omitted. For example, when inserting a plate-shaped insulating member, the operation of folding the insulating member is not required. Although the conveying member is constituted by the first to fourth members, the conveying member may be constituted by an appropriate number of members (including one). Although a conveying member having a cross-shaped insulating member insertion hole is used, the shape of the insulating member insertion hole of the conveying member is not limited to the shape of the embodiment. For example, when inserting a plate-shaped insulating member, a conveying member having a linear insulating member insertion hole (for example, the insertion hole portion 711a shown in FIG. 12) can be used. In this case, it is preferable to provide the conveying member with a slip-out prevention portion that prevents the plate-shaped insulating member from slipping out of the insulating member insertion port while the conveying member is moving. Although a conveying member having an insulating member insertion hole is used, the conveying member may be of various configurations capable of conveying an insulating member. Although two lines (two systems) of insulating material supplying devices, folding devices, and conveying devices are provided, the number of lines (systems) can be set to an appropriate number including one. The configuration of the extrusion device (extrusion member) that extrudes the insulating member is not limited to the configuration described in the embodiment. The configuration of the guide portion that guides the insulating member extruded by the extrusion device into the insulating member insertion space of the stator is not limited to the configuration described in the embodiment. Also, a part or all of the guide portion that guides the insulating member extruded by the extrusion member into the insulating member insertion space of the stator may be omitted. For example, when inserting a plate-shaped insulating member, a guide portion including an insulating member guide hole 832 may be used. Each of the configurations described in the embodiments can be used alone, or multiple appropriately selected configurations can be used in combination. [Explanation of symbols]
