  The work receiving unit 40 is provided on the stage 19 between the core support unit 20 and the winding processing unit 30. The workpiece receiver 40 has a function of moving the support member 41 on which the movable core 10 can be placed in the vertical direction. When the movable core 10 is attached to the core support portion 20, the movable core 10 is placed on the support member 41.

  Next, a method for winding the bind tape 15 around the movable core 10 by the bind tape winding device 1 will be described. FIG. 4 shows a flowchart of an “insulating member winding method” according to the first embodiment.

  Initially, the structure of the movable core 10 by which the bind tape 15 is wound using the bind tape winding apparatus 1 is demonstrated based on Fig.5 (a). The movable core 10 includes a substantially cylindrical core portion 11, a main body portion 121 having an outer diameter smaller than that of the core portion 11, and a plurality of “predetermined portions on the radially outer side of the commutator provided on the radially outer side of the main body portion 121. The commutator 12 is formed from the connecting portion 122, the winding 13 provided in the core portion 11 and electrically connected to the commutator 12, and the shaft 14 provided on the central axis of the core portion 11 and the commutator 12. Etc.

  The movable core 10 is connected to the core portion 11 and the main body portion 121 of the commutator 12 via the shaft 14. Further, the end portion 131 of the winding 13 protrudes from the core portion 11 toward the commutator 12 and is connected to the connection portion 122 provided at the end portion of the commutator 12 on the core portion 11 side. Here, the connecting portion 122 is formed to have an opening in the radially outward direction of the commutator 12, and the end 131 of the winding 13 is connected to the commutator 12 from the radially outward direction via the opening. It is inserted into the part 122. The end portion 131 inserted into the connection portion 122 is fixed in the connection portion 122 by, for example, fusing welding.

  When the bind tape 15 is wound around the movable core 10 using the bind tape winding device 1, the movable core 10 shown in FIG. 5A is assembled to the core support portion 20 using the work receiving portion 40. The movable core 10 assembled to the core support unit 20 moves in the direction of the central axis φ and is brought into contact with the center pin 362 of the winding processing unit 30. Thereby, the movable core 10 is centered with respect to the winding processing unit 30.

  In the winding method of the bind tape 15 by the bind tape winding device 1, in the first step (hereinafter, “step” is omitted, and simply indicated by “S”) 101 as the “winding start portion contact step”, the bind is performed. The winding start portion 150 of the tape 15 is brought into contact with the radially outer side of the connection portion 122 of the commutator 12. For example, a bind tape supply device (not shown) that rotatably supports a bind tape 15 wound in a roll on another member is provided in the vicinity of the bind tape winding device 1. The front end portion of the bind tape 15 supported by the bind tape supply device is brought into contact with the radially outer side of the connection portion 122 of the commutator 12. The front end portion of the bind tape 15 becomes a winding start portion 150 of the bind tape 15 that is wound around the connection portion 122 of the commutator 12.

  Next, in S <b> 102 as the “winding start portion pressing step”, the winding start portion 150 of the bind tape 15 that contacts the connection portion 122 is pressed against the connection portion 122 by the pressing bar 361 of the pressing member 36. Specifically, as shown in FIG. 3, the two pressing bars 361 are brought into contact with the winding start portion 150 of the bind tape 15 so that the winding start portion 150 does not deviate from the contacted portion in S101. Press down on.

  Next, in S <b> 103 as “winding step” and “first step”, the binding tape 15 is connected to the connecting portion 122 in the radial direction using the guide member 37 while rotating the movable core 10 and the pressing member 36 in the same direction. Wind it outward. In S <b> 103, the movable core 10 and the pressing member 36 are gradually rotated in the same direction by the same angle while the winding member 150 of the binding tape 15 is pressed against the connecting portion 122 by the pressing member 36. For example, it rotates counterclockwise when viewing the direction of the movable core 10 from the core support 20 in FIG. Thereby, the bind tape 15 is pulled out from the bind tape supply device and wound around the connecting portion 122. At this time, as shown in FIG. 6, the guide member 37 is moved to the ground side by the cylinder 372 so as to come into contact with the bind tape 15 around which the roller 371 is wound on the top side of the commutator 12, and from the bind tape supply device. The drawn out bind tape 15 is guided to be wound around the outer side in the radial direction of the connecting portion 122. When the movable core 10 and the pressing member 36 are rotated by about 270 °, the pressing member 36 and the guide member 37 are as shown in FIG. 6 showing the periphery of the movable core 10 viewed from the same direction as the side view shown in FIG. Positional relationship. Here, the bind tape 15 wound outside in the radial direction of the connection part 122 other than the connection part 122 around which the winding start part 150 is wound is referred to as a first intermediate part 151 that connects to the winding start part 150. The first intermediate portion 151 is wound around the outer circumference in the radial direction of the connecting portion 122 (see FIGS. 7 and 8).

  In S103, when the first intermediate portion 151 of the bind tape 15 is wound about one turn on the outer side in the radial direction of the connection portion 122, next, in S104 as "winding step" and "second step", the guide member 37 and the bind tape 15 are separated, and the bind tape 15 is wound. Specifically, the guide member 37 is moved to the top side by the cylinder 372. On the other hand, the movable core 10 and the pressing member 36 are gradually rotated by the same angle in the same direction as in S103. Thereby, the 2nd intermediate part 152 connected to the 1st intermediate part 151 is wound to the radial direction outer side of the already wound 1st intermediate part 151 (refer FIG. 7, 8). The second intermediate portion 152 is wound about one turn.

  When the second intermediate portion 152 of the bind tape 15 is wound about one turn on the radially outer side of the first intermediate portion 151 in S104, next, in S105 as a “winding step” and a “third step”, guidance is performed. The member 37 and the bind tape 15 are brought into contact again, and the bind tape 15 is wound. Specifically, the guide member 37 is moved to the ground side by the cylinder 372. On the other hand, the movable core 10 and the pressing member 36 are gradually rotated by the same angle in the same direction as in S104. As a result, the third intermediate portion 153 and the winding end portion 154 connected to the second intermediate portion 152 are wound on the outer side in the radial direction of the already wound second intermediate portion 152 (see FIGS. 7 and 8). The third intermediate portion 153 is wound about one turn. The winding end 154 is an end of the bind tape 15 cut by the bind tape supply device.

  When the third intermediate portion 153 and the winding end portion 154 of the bind tape 15 are wound on the radially outer side of the second intermediate portion 152 in S105, the guide member 37 is then moved in S106 as the “first end step”. Separated from the winding end 154. Specifically, the guide member 37 is moved to the top side by the cylinder 372. When the guide member 37 is separated from the winding end portion 154, the pressing member 36 keeps pressing the winding start portion 150, and is in a state as shown in FIG.

Finally, in S107 as the “second end step”, the pressing member 36 is extracted from between the wound bind tapes 15, and the pressing of the winding start portion 150 of the bind tape 15 by the pressing members 36 is released. The movable core 10 at this time has an appearance as shown in FIG.
Thereafter, as shown in FIG. 9, the bind ring 17 is assembled to the outer side in the radial direction of the wound bind tape 15 by, for example, light press fitting. The bind ring 17 prevents the end portion 131 of the winding 13 connected to the connection portion 122 of the commutator 12 from dropping from the connection portion 122 due to centrifugal force when the movable core 10 rotates.
In this way, the movable core 10 (see FIG. 5C) having the bind tape 15 and the bind ring 17 is completed.

In the winding method of the bind tape 15 according to the first embodiment, first, the winding start portion 150 of the bind tape 15 wound around the connection portion 122 of the commutator 12 is pressed against the connection portion 122 using the pressing member 36. While the binding member 15 is wound around the movable core 10, the pressing member 36 presses the winding start portion 150 to the position where it first contacts the connecting portion 122. The deviation of 150 is eliminated.
The guide member 37 guides the wound bind tape 15 while the winding start portion 150 is pressed by the pressing member 36 at a position where the winding start portion 150 first contacts the connection portion 122. As a result, the degree of adhesion of the winding start portion 150, the first intermediate portion 151, the second intermediate portion 152, the third intermediate portion 153, and the winding end portion 154 of the bind tape 15 wound around the movable core 10 is adjusted. The shape of the bind tape 15 such as the radial thickness can be made a desired shape.

  As described above, in the winding method of the bind tape 15 according to the first embodiment, the guide member 37 is used to hold the winding start portion 150 so as to remain at the position where the connection portion 122 first contacts using the pressing member 36. The degree of adhesion between the bind tapes 15 to be rotated is adjusted. Thereby, in the wound bind tape 15, a moderate gap is formed between the bind tapes 15 adjacent in the radial direction. Therefore, depending on the surrounding environment where the bind tape 15 is wound, the bind tape 15 Even if the characteristic changes, it is absorbed by the gap, and the shape of the bind tape 15 can be made a shape that allows the bind ring 17 to be lightly press-fitted. Therefore, the bind ring 17 provided on the outer side in the radial direction of the wound bind tape 15 can be reliably fixed by the bind tape 15.

  In the winding method of the bind tape 15 according to the first embodiment, the second intermediate portion 152 of the bind tape 15 is wound without coming into contact with the guide member 37. Thereby, an appropriate gap can be formed between the bind tapes 15 adjacent in the radial direction. Therefore, the bind ring 17 can be more securely fixed by the bind tape 15.

  In the winding method of the bind tape 15 according to the first embodiment, the first intermediate portion 151 that comes into contact with the guide member 37 is wound about one turn. The first intermediate portion 151 wound about one turn is wound on the radially outer side of the winding start portion 150 pressed by the pressing member 36. Thereby, the winding start part 150 can be reliably pressed to the original position also by the 1st intermediate part 151. FIG. Therefore, the bind ring 17 can be more securely fixed by the bind tape 15.

  In the winding method of the bind tape 15 according to the first embodiment, the guide member 37 abuts until the winding end portion 154 is wound. Thereby, since the winding end part 154 is reliably wound around the movable core 10, the assembly failure of the bind ring 17 due to the winding failure is eliminated. Therefore, the bind ring 17 can be reliably assembled to the movable core 10.

The bind tape winding device 2 as the “insulating member winding device” according to the second embodiment includes a heating unit 50 at a position off the central axis φ on the stage 19. The heating unit 50 includes a power supply unit 51, a heater 52, a rail 53, and the like.
The power supply unit 51 is electrically connected to an external power source (not shown). The external power supply supplies power to the power supply unit 51. The power supplied to the power supply unit 51 is supplied to the heater 52.
The heater 52 is formed so as to protrude from the power supply unit 51 in the direction of the central axis φ. The end of the heater 52 opposite to the side connected to the power supply unit 51 has a tip wall 521 that can contact the outer wall 155 on the radially outer side of the bind tape 15 wound around the movable core 10 ( (See FIG. 12).
The rail 53 is provided substantially perpendicular to the central axis φ. The rail 53 supports the power supply unit 51 and the heater 52 so as to move in a direction substantially perpendicular to the central axis φ (the direction of the arrow F21 in FIG. 10).

  Next, a method for winding the bind tape 15 around the movable core 10 by the bind tape winding device 2 will be described. FIG. 11 shows a flowchart of “a method of winding an insulating member” according to the second embodiment.

In the winding method of the bind tape 15 by the bind tape winding device 2, the winding start portion of the bind tape 15 is similar to S101 of the winding method of the first embodiment in S201 as the “winding start portion contact step”. 150 is brought into contact with the radially outer side of the connecting portion 122 of the commutator 12.
Next, in S202 as the “winding start portion pressing step”, similarly to S102 of the winding method of the first embodiment, the winding start portion of the bind tape 15 that contacts the connecting portion 122 by the pressing bar 361 of the pressing member 36. 150 is pressed against the connecting portion 122.
Next, in S203 as the “winding step” and the “first step”, the guide member is rotated while rotating the movable core 10 and the pressing member 36 in the same direction as in S103 of the winding method of the first embodiment. 37 is used to wind the first intermediate portion 151 of the bind tape 15 outward in the radial direction of the connection portion 122.

Next, in S204 as the “winding step” and the “second step”, the guide member 37 and the bind tape 15 are separated from each other in the same manner as in S104 of the winding method of the first embodiment, and the first step of the bind tape 15 is performed. 2 The intermediate part 152 is wound.
Next, in S205 as the “winding step” and the “third step”, the guide member 37 and the bind tape 15 are brought into contact again in the same manner as in S105 of the winding method of the first embodiment. The third intermediate part 153 is wound.
Next, in S206 as the “second end step”, the pressing of the winding start portion 150 of the bind tape 15 by the pressing member 36 is released as in S107 of the winding method of the first embodiment.

Next, in S207 as a “thermal bonding step”, the winding end portion 154 and the second intermediate portion 152 are thermally bonded using the heater 52. The positional relationship between the bind tape 15 and the heater 52 at this time is shown in FIG.
As shown in FIG. 12, in S <b> 207, the heating unit 50 is moved so that the tip wall 521 of the heater 52 contacts the outer wall 155 of the bind tape 15. The adhesive applied to the bind tape 15 is melted by the heat transmitted from the heated tip wall 521, and the winding end portion 154 and the second intermediate portion 152 are thermally bonded. At this time, as shown in FIG. 12, the main body 121 around which the bind tape 15 is wound is turned counterclockwise (in the direction of arrow F22 in FIG. 12), for example, by about 30 °, and the winding end 154 The second intermediate portion 152 may be bonded over a certain length.

  Next, in S208 as the “first end step”, the guide member 37 is separated from the winding end portion 154, as in S106 of the winding method of the first embodiment. Thereby, the winding process of the bind tape 15 around the movable core 10 is completed.

  In the winding method of the bind tape 15 according to the second embodiment, the winding end portion 154 of the bind tape 15 wound around the movable core 10 is thermally joined to the second intermediate portion 152 by heating. As a result, after the guide member 37 is separated from the winding end portion 154, the winding end portion 154 is in the second period from when the bind tape 15 is wound to when the bind ring 17 is press-fitted or when the bind ring 17 is press-fitted. The separation from the intermediate portion 152 is prevented. Therefore, the second embodiment has the same effect as the first embodiment, and can prevent the press-fitting failure of the bind ring 17 due to the collapse of the bind tape 15.

(Third embodiment)
Next, an insulating member winding method and an insulating member winding device according to a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the point of adjusting the tension of the insulating member wound around the movable core in the winding method of the insulating member and the point that the tension adjusting unit capable of adjusting the tension of the insulating member is provided are the first embodiment. Different from form. In addition, the same code | symbol is attached | subjected to the site | part substantially the same as 1st Embodiment, and description is abbreviate | omitted.

The bind tape winding device 3 as the “insulating member winding device” according to the third embodiment includes a bind tape supply unit 60 that supplies the bind tape 15 to be wound. The bind tape supply unit 60 includes a tape supply unit 61, a rotation speed adjustment unit 62 as a “tension adjustment unit”, a control unit 63, and the like.
The tape supply unit 61 is, for example, a cylindrical rotatable member provided so that the bind tape 15 before being wound around the connection unit 122 can be supplied. A rotation shaft 621 included in the rotation speed adjustment unit 62 is provided at the center of the tape supply unit 61.
The rotation speed adjustment unit 62 adjusts the rotation speed of the tape supply unit 61 via the rotation shaft 621 described above. Thereby, the supply speed of the bind tape 15 and the tension of the bind tape 15 when the bind tape 15 is wound around the movable core 10 are adjusted.
The control unit 63 controls driving of the rotation speed adjustment unit 62.

  In the bind tape winding device 3 according to the third embodiment, the tension of the bind tape 15 wound around the movable core 10 is changed according to the winding state of the bind tape 15. For example, when winding the winding start portion 150 and the first intermediate portion 151, the tension of the bind tape 15 is reduced, and the winding start portion 150 pressed by the connecting portion 122 by the pressing member 36 is connected to the pressing member 36 and the connecting portion. Do not come out from between 122. Further, when winding the second intermediate portion 152 and thereafter, the tension of the bind tape 15 is adjusted in consideration of the completion when the bind tape 15 has been wound. Thereby, the outer diameter of the site | part in which the bind ring 17 is assembled | attached can be adjusted. Therefore, the third embodiment has the same effect as the first embodiment, and manages the outer diameter of the bind tape 15 after winding the bind tape 15 with high accuracy, and the press-fitted bind ring 17 falls off. This can be prevented.

However, the wound length is not limited to this. Each may be wound about a half turn, or may be wound more than one turn. Further, the length of the bind tape wound around the movable core may not be about three rounds.

  (C) In the first embodiment, after the guide member is separated from the winding end portion of the bind tape in the “first end step”, from between the bind tapes around which the pressing member is wound in the “second end step”. I decided to pull it out. However, the order of the “first end step” and the “second end step” is not limited to this. The guide member may be separated from the winding end portion of the bind tape after the pressing member is extracted from between the bind tapes that are wound.
