Description

[Technical Field]

[0001] The present invention relates to a metal ribbon winding method and a metal ribbon winding system. [Background technology]

[0002] Electric vehicles, hybrid vehicles, and other vehicles are equipped with motors for driving. Motor cores (stators and rotors) are one of the motor components. A motor core is constructed by laminating thin sheets of electromagnetic steel, for example, 1 mm or less, pressed into a die. Because thinner sheets have lower iron loss due to eddy currents, efficient production of thinner sheets has been investigated. One possible method for this is to produce a thin ribbon (thin film) by rapidly solidifying molten metal using a single-roll process, and then processing this ribbon appropriately to use it as the electromagnetic steel sheet for the motor core. The single-roll process is well known and involves continuously producing a metal ribbon (amorphous metal ribbon) by ejecting molten metal onto the surface of a rapidly rotating metal cooling roller and rapidly solidifying it on the cooling roller. When producing metal ribbon on an industrial scale, the rapidly solidified metal ribbon is wound around a winding roll and recovered. A method for winding a metal strip around a winding roll is described in, for example, Patent Document 1. [Prior art documents] [Patent documents]

[0010] Hereinafter, an embodiment of the present invention (hereinafter referred to as "the present embodiment") will be described in detail with reference to the drawings. Note that each drawing is merely a schematic illustration to allow a sufficient understanding of the present invention. Therefore, the present invention is not limited to the illustrated examples. Furthermore, in each drawing, common or similar components are given the same reference numerals, and redundant explanations thereof will be omitted.

[0011] [First embodiment] This embodiment provides a metal ribbon winding method and a metal ribbon winding system that shortens the process cycle time and also reduces the ribbon storage area (stock area 24 described below).

[0012] <Configuration of Metallic Ribbon Winding System> The configuration of a metal strip winding system 100A according to the first embodiment will be described below with reference to Figs. 1 to 3. Fig. 1 is a configuration diagram of the metal strip winding system 100A according to the first embodiment. In Fig. 1, the "upstream side" and the "downstream side" are based on the movement direction of 11, which will be described later. Fig. 2 is a layout diagram of the metal strip winding system 100A. Fig. 3 is a configuration diagram of the vicinity of a connection means 41A of the metal strip winding system 100A.

[0013] 1, the metal strip winding system 100A includes equipment for manufacturing a metal strip inside a work room 101. The work room 101 has a plurality of pillars 102 standing on a base plate 105, and each pillar 102 supports a plurality of wall surfaces 103.

[0014] The metal strip winding system 100A is equipped with a supply section 20, a stock area 24, a ribbon cutting jig 30A, a leader connecting jig 40A, and a winding machine 70 inside a work room 101 as equipment for manufacturing metal strips.

[0015] The supply unit 20 is a component that supplies ribbon 11 as a thin metal strip. Ribbon 11 is connected to a leader 12, which will be described later. The supply unit 20 includes a metal cooling roller 21, a rotation shaft 22a of the cooling roller 21, a cooling roller rotation means 22, and a tundish 25. The cooling roller rotation means 22 is an electric motor connected to the rotation shaft 22a and driving the rotation shaft 22a. The tundish 25 is a container for molten metal 10 and is disposed directly above the cooling roller 21. The lower part of the tundish 25 is formed in a funnel shape. A stopper rod 26 is disposed inside the tundish 25. The stopper rod 26 is a member that adjusts the flow rate of molten metal 10 flowing from the tundish 25 onto the surface of the cooling roller 21. The stopper rod 26 has a conical lower part and a cylindrical upper part, and moves up and down. When the stopper rod 26 is positioned at the lowest end, the stopper rod 26 blocks the opening at the bottom of the tundish 25. Therefore, in this case, the flow rate of the molten metal 10 becomes zero. When the stopper rod 26 rises, the opening at the bottom of the tundish 25 opens. Then, the molten metal 10 in the tundish 25 flows down onto the surface of the cooling roller 21. The cooling roller 21 is rotated at high speed by a rotation shaft 22a connected to the cooling roller rotation means 22. The supply unit 20 causes the molten metal 10 to flow down onto the surface of the cooling roller 21, which is rotating at high speed, from directly above the cooling roller 21. This causes the molten metal 10 to rapidly solidify on the cooling roller 21. The supply unit 20 then releases the ribbon 11, which is a thin film of the rapidly solidified molten metal 10, from the surface of the cooling roller 21 via the flight tube 23, while flying it to the stock area 24. The flight tube 23 is a pipe with an internal space for the ribbon 11 of thin film molten metal 10 to fly. The ribbon 11 is discharged from the flying tip 11a side toward the stock field 24. In this way, the supply unit 20 continuously produces the ribbon 11, which is an amorphous metal thin strip, and stores it in the stock field 24.

[0016] The stock area 24 is a component that stocks ribbons 11, which are thin metal ribbons. Ribbon splicing robots 50A are arranged around the stock area 24. The ribbon splicing robot 50A is a component that scoops up the middle portion of the thin metal ribbon flying toward the stock area 24 and supplies it to the ribbon cutting jig 30A. Incidentally, the production of ribbons 11 using the single-roll method is performed at a very high speed. For this reason, if a configuration were to be implemented in a production site with limited space in which the leading end of the ribbon 11 is set on the winding roll 14 as soon as it emerges and immediately wound, it would become heavy, long, and expensive. Therefore, the thin metal ribbon winding system 100A according to this embodiment is configured to scoop up the middle portion of the thin metal ribbon (ribbon 11) flying at the exit of the flight tube 23, cut and grip it, connect the ribbon 11 to a leader 12 (described later), and wind it. In addition, the winding speed of ribbon 11 onto winding roll 14 is set to be equal to or greater than the manufacturing speed of ribbon 11, since the manufacturing of the metal ribbon (ribbon 11) and the winding of the metal ribbon (ribbon 11) are carried out simultaneously in parallel.

[0017] Ribbon cutting jig 30A is a jig that cuts an appropriate portion of ribbon 11, such as the rear end, to make it easier to connect to leader 12. Ribbon cutting jig 30A is provided at the front upper part of stock area 24. Ribbon cutting jig 30A, together with ribbon connection robot 50A, constitutes cutting and gripping unit 30 that cuts and grips ribbon 11.

[0018] Leader connecting jig 40A is a jig that connects ribbon 11 to leader 12. Leader connecting jig 40A is provided at approximately the same position in the front-to-rear direction as ribbon cutting jig 30A, but at a higher position than ribbon cutting jig 30A (FIG. 3). Leader 12 is the portion to be connected of the thin metal ribbon that remains on take-up roll 14 set in take-up roll rotating means 71 of winding machine 70. An operator has previously adhered adhesive tape 13 (FIG. 3) to the end (remaining tip portion 12b (FIG. 3)) of leader 12. Leader connecting jig 40A applies pressure (presses down) to ribbon 11 and leader 12, thereby connecting ribbon 11 and leader 12 with adhesive tape 13.

[0019] The winding roll 14 is reused. When the ribbon 11 is unwound from the winding roll 14 on which it is wound and processed as needed, leaving a small amount of ribbon 11 behind and using this as leader 12 rather than unwinding the entire ribbon 11 from the winding roll 14 allows for more efficient attachment of the ribbon 11 to the winding roll 14 than attaching the ribbon 11 to an empty winding roll 14. The leader 12 may be something other than the remaining portion of the ribbon 11. Incidentally, by using adhesive tape 13 that has good releasability (releasable tape), it is possible to reuse the tape without wasting resources.

[0020] The winding machine 70 is a device that winds the ribbon 11 onto the winding roll 14. The winding machine 70 is provided behind the stock area 24. The winding machine 70 has a winding roll rotation means 71 on which the winding roll 14 is set. The winding roll 14 is a winding roll on which the leader 12, which is the connected portion of the metal strip to be connected to the ribbon 11, remains. In other words, the winding roll 14 is a winding roll that has been used and still has a small amount of the metal strip (leader 12) remaining. The winding roll rotation means 71 is rotated in the direction of arrow A14 by a winding motor 72, thereby winding the ribbon 11 connected to the leader 12 onto the winding roll 14. The winding machine 70 has a winding nip roller 73, a roll diameter measurement unit 74, a feed roller 78, and a feed control motor 79.

[0021] The winding nip roller 73 is a component that sandwiches the metal thin strip (the leader 12 and the ribbon 11 connected to the leader 12) between itself and the winding roll .

[0022] The roll diameter measuring unit 74 is a component that measures the roll diameter of the winding roll 14. The roll diameter measuring unit 74 measures the roll diameter of the winding roll 14 by moving together with the winding nip roller 73 in the radial direction of the winding roll 14 (in the direction of arrow A73, which is the up and down direction in the illustrated example).

[0023] The feed roller 78 is a component that feeds the metal ribbon (the leader 12 and the ribbon 11 connected to the leader 12) toward the take-up roll 14. The feed control motor 79 is a component that controls the rotation speed of the feed roller 78. Two feed rollers 78 are arranged facing each other in the vertical direction. Of the two feed rollers 78, one of the feed rollers 78 (the upper feed roller 78 in the illustrated example) is configured to move in the direction of arrow A78 (vertical direction) so that a gap can be created when an operator sets the leader 12, making it easier to perform the work. A ribbon guide bar 60 is provided between the feed roller 78 and the leader connecting jig 40A to stretch the metal ribbon (the leader 12 and the ribbon 11 connected to the leader 12) and eliminate twists in the metal ribbon.

[0024] Fig. 2 shows an example of the arrangement of the components of the metal ribbon winding system 100A as viewed from above. As shown in Fig. 2, the metal ribbon winding system 100A is provided with a flight tube 23 in front of (upstream of) the stock area 24. In addition, in the metal ribbon winding system 100A, a ribbon cutting jig 30A, a leader connection jig 40A, and a ribbon connection robot 50A are arranged facing each other across the stock area 24. In addition, the metal ribbon winding system 100A is provided with a winding machine 70 behind (downstream of) the stock area 24.

[0025] 3 shows the configuration of the vicinity of the splicing means 41A of the metal ribbon winding system 100A. The metal ribbon winding system 100A includes a ribbon cutting jig 30A that functions as the cutting and holding unit 30, and a ribbon splicing robot 50A. The ribbon cutting jig 30A has a stopper 31A that fixes the ribbon 11. The stopper 31A has a fixedly disposed fixed shaft 31Aa and a pressure shaft 31Ab that sandwiches the ribbon 11 between the stopper 31Aa and the fixed shaft 31Aa. The stopper 31A also has an air cylinder 31Ac that moves the pressure shaft 31Ab in the direction of arrow A31A (toward or away from the fixed shaft 31Aa), and a ribbon positioning block 31Ad that determines the position of the ribbon 11 in the width direction. The ribbon splicing robot 50A also includes a robot hand 51A, which has a blade-shaped ribbon cutter 51Aa.

[0026] The metal ribbon winding system 100A also includes a leader connecting jig 40A. The leader connecting jig 40A includes a connecting means 41A, which has a cushion plate 41Aa, a pressure receiving cushion 41Ab, and a fixed bracket 41Ac. The cushion plate 41Aa is an elastic plate. The pressure receiving cushion 41Ab is a cushion that receives pressure applied to the metal ribbon via the cushion plate 41Aa. The fixed bracket 41Ac is a member that supports the cushion plate 41Aa and the pressure receiving cushion 41Ab.

[0027] 3, the metal ribbon winding system 100A causes the ribbon 11 to fly in the direction of arrow A11a, and cuts and grips a midpoint of the ribbon 11 while it is flying with the robot hand 51A of the ribbon splicing robot 50A. After cutting the ribbon 11, the metal ribbon winding system 100A moves the robot hand 51A along arrow A50Aa and abuts the side of the ribbon 11 against the ribbon positioning block 31Ad, thereby adjusting the left-right position of the ribbon 11. In this way, the metal ribbon winding system 100A positions the cut leading end 11b of the ribbon 11 opposite the remaining leading end 12b of the leader 12.

[0028] Then, the metal ribbon winding system 100A moves the pressure shaft 31Ab in the direction toward the fixed shaft 31Aa along the arrow A31A. The adhesive tape 13 is adhered to the remaining tip portion 12b of the leader 12. Therefore, at this time, the cut tip portion 11b of the ribbon 11 and the remaining tip portion 12b of the leader 12 are adhered to each other via the adhesive tape 13. Furthermore, once the cut tip portion 11b of the ribbon 11 and the remaining tip portion 12b of the leader 12 are adhered to each other, the metal ribbon winding system 100A retracts the ribbon cutter 51Aa to a predetermined retract position (the stop origin P11 shown in FIG. 5A or 6C ) along the arrow A31A.

[0029] <Operation of the metal ribbon winding system> The operation of the metal strip winding system 100A will be described below with reference to Fig. 4 to Fig. 6C. Fig. 4 is a flowchart showing the operation of the metal strip winding system 100A. Figs. 5A to 5J are explanatory diagrams showing the operation of the metal strip winding system 100A. Figs. 6A to 6C are explanatory diagrams showing the operation of the ribbon cutter 51Aa of the metal strip winding system 100A.

[0030] As shown in FIG. 4, in the metal strip winding system 100A, first, an operator or a robot (not shown) sets the winding roll 14 on which the leader 12, which is the connected portion of the metal strip, remains on the winding roll rotating means 71 (step S110).

[0031] Next, the metal ribbon winding system 100A drives the supply unit 20 to start the flight of the ribbon 11 from the flight tube 23 (step S120). Note that, to ensure the safety of workers, the metal ribbon winding system 100A is configured to execute the processes from step S120 onwards only when no workers remain inside the work room 101. That is, to ensure the safety of workers, the metal ribbon winding system 100A is configured to prevent workers from entering the work room 101 when the metal ribbon (ribbon 11) is being wound around the winding roll 14. Note that the metal ribbon winding system 100A is preferably configured to produce only an amount of metal ribbon (ribbon 11) that can be wound around a single winding roll 14. Furthermore, the metal ribbon winding system 100A is preferably configured to prevent the winding roll 14 from being replaced while the molten metal 10 is flowing down from the tundish 25 onto the surface of the cooling roller 21.

[0032] Next, the metal ribbon winding system 100A drives the cutting and holding unit 30 to cut and hold the ribbon 11 (step S130).

[0033] Next, the metal ribbon winding system 100A drives the leader connecting jig 40A to connect the leader 12 and the ribbon 11 (step S140). That is, the metal ribbon winding system 100A connects the ribbon 11, which is a metal ribbon, to the leader 12. Note that instead of deleting the process of step S120, the metal ribbon winding system 100A can stock the ribbon 11 in the stock area 24 before the process of step S110, and connect the ribbon 11 stocked in the stock area 24 to the leader 12. In this case, to ensure the safety of workers, the process is configured to be executed only when no workers remain inside the work room 101.

[0034] Next, the metal ribbon winding system 100A drives the winding roll rotating means 71 to wind the metal ribbon (ribbon 11) around the winding roll 14 (step S150). When the winding of the metal ribbon (ribbon 11) around the winding roll 14 is completed, the metal ribbon winding system 100A stops the winding roll rotating means 71.

[0035] In steps S130 and S140, the metal ribbon winding system 100A operates the ribbon cutting jig 30A, the connecting means 41A, and the ribbon cutter 51Aa, as shown in, for example, FIGS. 5A to 5J.

[0036] FIG. 5A shows a state in which the ribbon 11 is ready to be picked up. In the example shown in FIG. 5A, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the stop origin P11 to the pick-up origin P12. The stop origin P11 is a retracted position for the ribbon cutter 51Aa. The stop origin P11 is located outside the stock area 24. In the example shown in FIG. 5A, the stop origin P11 is located further below the stopper 31A of the ribbon cutting jig 30A and forwardly away from the fixed bracket 41AC of the connection means 41A. The pick-up origin P12 is the position of the ribbon cutter 51Aa before it picks up the ribbon 11. The pick-up origin P12 is preferably located inside the stock area 24 and directly below the outlet of the flight tube 23. In the example shown in FIG. 5A, pick-up origin P12 is located below stopper 31A of ribbon cutting jig 30A and between fixed shaft 31Aa and pressure shaft 31Ab.

[0037] FIG. 5B shows the state in which the ribbon 11 is picked up. In the example shown in FIG. 5B, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the pick-up origin P12 to the pick-up point P13. The pick-up point P13 is the position of the ribbon cutter 51Aa when the ribbon 11 is picked up. In the example shown in FIG. 5B, the pick-up point P13 is located above the stopper 31A of the ribbon cutting jig 30A and between the fixed shaft 31Aa and the pressure shaft 31Ab. In other words, the pick-up point P13 is a position where the ribbon cutter 51Aa is disposed opposite the cushion plate 41Aa (in other words, disposed side by side). FIG. 6A shows the position of the ribbon cutter 51Aa as viewed from behind in the state shown in FIG. 5B. The ribbon 11 and the leader 12 are disposed at positions offset in the left-right direction.

[0038] FIG. 5C shows a state in which the ribbon 11 is being prepared for cutting. In the example shown in FIG. 5C, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the pick-up point P13 to the cutting origin P14. The cutting origin P14 is the position of the ribbon cutter 51Aa before the ribbon 11 is cut. The cutting origin P14 is shifted left and right from the pick-up point P13. FIG. 6B shows the position of the ribbon cutter 51Aa as seen from behind in the state shown in FIG. 5C. The ribbon 11 and the leader 12 are positioned so that they overlap left and right. Thereafter, the metal ribbon winding system 100A moves the ribbon 11 in the front-to-rear direction to overlap the ribbon 11 and the leader 12 via the adhesive tape 13.

[0039] Fig. 5D shows the fixed state of ribbon 11. In the example shown in Fig. 5D, metal ribbon winding system 100A moves pressure shaft 31Ab toward fixed shaft 31Aa. As a result, metal ribbon winding system 100A sandwiches ribbon 11 between pressure shaft 31Ab and fixed shaft 31Aa, thereby fixing ribbon 11.

[0040] Fig. 5E shows a state in which the ribbon 11 is cut. In the example shown in Fig. 5E, the metal ribbon winding system 100A cuts the ribbon 11 by moving the ribbon cutter 51Aa from the cutting origin P14 to the cutting point P15. The cutting point P15 is the position of the ribbon cutter 51Aa when the ribbon 11 is cut. The cutting point P15 is set above the cutting origin P14.

[0041] Fig. 5F shows the adhesive state of the leader 12. In the example shown in Fig. 5F, the metal ribbon winding system 100A adhesively bonds the ribbon 11 and the leader 12 via the adhesive tape 13 by moving the ribbon cutter 51Aa from the cutting point P15 to the adhesive point P16. The adhesive point P16 is the position of the ribbon cutter 51Aa when the ribbon 11 and the leader 12 are adhered. The adhesive point P16 is located closer to the cushion plate 41Aa than the cutting point P15, that is, at a position where the ribbon cutter 51Aa is pressed against the cushion plate 41Aa.

[0042] 5G shows the released state of ribbon 11. In the example shown in FIG. 5G, metal ribbon winding system 100A moves pressure shaft 31Ab away from fixed shaft 31Aa. As a result, metal ribbon winding system 100A releases ribbon 11 from being pinched between pressure shaft 31Ab and fixed shaft 31Aa, and releases ribbon 11. Note that the end of ribbon 11 that was not connected to leader 12 via adhesive tape 13 falls and enters stock area 24.

[0043] 5H to 5J show the ribbon cutter 51Aa returning to its origin. In the example shown in FIG. 5H, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the bonding point P16 (FIG. 5G) to the cutting point P15, i.e., to the side away from the cushion plate 41Aa. Next, in the example shown in FIG. 5I, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the cutting point P15 (FIG. 5H) to the relay point P17. The relay point P17 is an intermediate position for moving the ribbon cutter 51Aa to the rest origin P11. Next, in the example shown in FIG. 5J, the metal ribbon winding system 100A moves the ribbon cutter 51Aa from the relay point P17 (FIG. 5H) to the rest origin P11. FIG. 6C shows the movement positions of the ribbon cutter 51Aa as viewed from behind in the state shown in FIGS. 5H to 5J.

[0044] Thereafter, the metal strip winding system 100A performs the process of step S150 shown in FIG.

[0045] Thereafter, the processes of steps S110 to S150 shown in Fig. 4 are repeated. At this time, in the process of step S110 shown in Fig. 4, a robot (not shown) sets the winding roll 14 with the remaining leader 12 on the winding roll rotating means 71. In this way, the metal ribbon winding system 100A can simply connect the ribbon 11 to the leader 12, without directly attaching the ribbon 11 to the winding roll 14. Therefore, the metal ribbon winding system 100A can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0046] The metal ribbon winding system 100A can adjust the operating speed of the cutting and holding unit 30 and the operating speed of the leader connecting jig 40A according to the winding speed of the ribbon 11 around the winding roll 14 by the winder 70 and the rotation speed of the feed roller 78. This makes it possible for the metal ribbon winding system 100A to prevent excessive tension from being applied to the ribbon 11 during the winding operation of the ribbon 11 and to prevent slack from occurring in the ribbon 11. Therefore, in this respect as well, the metal ribbon winding system 100A can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0047] <Main features of the metal ribbon winding method> The metal ribbon winding method according to this embodiment has the following features.

[0048] (1) As shown in FIG. 4 , the metal ribbon winding method according to this embodiment includes a flying step (step S110), a metal ribbon connection step (step S140), and a metal ribbon winding step (step S150). The flying step (step S110) is a step of flying a metal ribbon from a flight tube 23. The metal ribbon connection step (step S140) is a step of connecting a leader 12, which is a portion of the metal ribbon remaining on a take-up roll 14 set in a take-up roll rotation means 71 of a winding machine 70 that winds up the metal ribbon, to an arbitrary portion of the metal ribbon flying from the flight tube 23 as a ribbon 11. The metal ribbon winding step (step S150) is a step of rotating the take-up roll rotation means 71 to wind the ribbon 11 around the take-up roll 14. The arbitrary portion of the ribbon 11 is a portion that is appropriately determined depending on the purpose, and is a portion that is adhered to the leader 12 via adhesive tape 13.

[0049] The metal ribbon winding method according to this embodiment produces a metal ribbon by, for example, liquid-quenching the metal ribbon using a single-roll method or the like, and flying it from a flight tube 23. Then, in the metal ribbon winding method according to this embodiment, an arbitrary portion of the metal ribbon is connected as a ribbon 11, which is a connection portion, to a portion to be connected (leader 12) of the metal ribbon remaining on a winding roll 14 set in a winding roll rotating means 71. In this metal ribbon winding method according to this embodiment, the production of the metal ribbon (ribbon 11) and the winding of the metal ribbon (ribbon 11) are performed simultaneously in parallel. Therefore, the metal ribbon winding method according to this embodiment can shorten the process cycle time. Ideally, the metal ribbon winding method according to this embodiment should be able to simultaneously complete the production of the metal ribbon (ribbon 11) and the winding of the metal ribbon (ribbon 11).

[0050] Furthermore, the metal ribbon winding method according to this embodiment scoops up, cuts, and grips the middle portion of the metal ribbon (ribbon 11) flying at the exit of the flight tube 23, and connects the leader 12 and ribbon 11 for winding. The metal ribbon winding method according to this embodiment makes it possible to store only the minimum amount of ribbon 11 in the stock area 24 by making the production speed of ribbon 11 and the winding speed of ribbon 11 approximately the same. Therefore, the metal ribbon winding method according to this embodiment can reduce the stock area 24 (ribbon storage area).

[0051] Furthermore, the metal ribbon winding method according to this embodiment allows for easy preparation for winding of the metal ribbon (ribbon 11) by avoiding direct attachment of the ribbon 11 to the winding roll 14. Therefore, the metal ribbon winding method according to this embodiment can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0052] (2) As shown in Figure 4, in the metal strip winding method described in (1) above, the winding roll 14 set in the winding roll rotating means 71 is a winding roll that has been used with a small amount of metal strip (leader 12) remaining.

[0053] In the metal ribbon winding method according to this embodiment, the ribbon 11 can be connected to the leader 12 by setting the winding roll 14 that has been used while a small amount of the metal ribbon (leader 12) remains on the winding roll rotating means 71. In the metal ribbon winding method according to this embodiment, the ribbon 11 does not need to be directly attached to the winding roll 14, and therefore the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14 can be improved.

[0054] (3) From another perspective, the metal ribbon winding method described in (1) above has the following characteristics. That is, as shown in FIG. 4 , the metal ribbon winding method according to this embodiment includes a flying step (step S110), a cutting and gripping step (step S130), a metal ribbon splicing step (step S140), and a metal ribbon winding step (step S150). The flying step (step S110) is a step of flying the metal ribbon from the flight tube 23. The cutting and gripping step (step S130) is a step of cutting and gripping any portion of the metal ribbon flying from the flight tube 23. The metal ribbon splicing step (step S140) is a step of splicing, as a ribbon 11, a leader 12, which is a portion to be spliced ​​of the metal ribbon remaining on the winding roll 14 set in the winding roll rotating means 71 of the winding machine 70 that winds the metal ribbon, to any portion of the metal ribbon cut and gripped in the cutting and gripping step. The metal ribbon winding step (step S150) is a step of rotating the winding roll rotating means 71 to wind the ribbon 11 around the winding roll .

[0055] In the metal ribbon winding method according to this embodiment, a metal ribbon (ribbon 11) is formed and a portion of it is stocked in a stock area 24. Then, in the metal ribbon winding method according to this embodiment, the ribbon 11 in this state is cut, gripped, and connected to the leader 12. In this metal ribbon winding method according to this embodiment, the ribbon 11 is not directly attached to the winding roll 14, and the metal ribbon (ribbon 11) can be prepared for winding with a simple operation. Therefore, the metal ribbon winding method according to this embodiment can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0056] The ribbon 11 wound around the winding roll 14 in this manner is processed appropriately to form thin electromagnetic steel sheets that constitute a motor core (a stator or rotor core), and these sheets are laminated to form a stator or rotor. As explained in the background art, ribbon 11 manufactured by the single roller method can be made thinner than when electromagnetic steel sheets are formed by rolling. Therefore, a motor core manufactured using this ribbon 11 has the advantage of being able to reduce iron loss compared to a rolled one.

[0057] <Main features of the metal ribbon winding system> The metal ribbon winding system 100A according to this embodiment has the following features.

[0058] (1) As shown in FIG. 1 , the metal ribbon winding system 100A according to this embodiment includes a flight tube 23 that causes the metal ribbon to fly, a winding roll rotation means 71, a connection means 41A, and a winding unit (winding motor 72). The flight tube 23 is a component that causes the metal ribbon to fly. The winding roll rotation means 71 is a component on which a winding roll 14 on which the metal ribbon remains is set. The connection means 41A is a component that connects a leader 12, which is a connected portion of the metal ribbon remaining on the winding roll 14, to an arbitrary portion of the metal ribbon flying from the flight tube 23 as a ribbon 11. The winding unit (winding motor 72) is a component that rotates the winding roll rotation means 71 to wind the ribbon 11 around the winding roll 14.

[0059] The metal ribbon winding system 100A according to this embodiment manufactures a metal ribbon by, for example, sending a liquid-quenched metal ribbon, such as by a single-roll method, flying it from a flight tube 23. The metal ribbon winding system 100A according to this embodiment then connects an arbitrary portion of the metal ribbon as a ribbon 11, which is a connection portion, to a portion to be connected (leader 12) of the metal ribbon remaining on a winding roll 14 set in a winding roll rotation means 71. The metal ribbon winding system 100A according to this embodiment simultaneously manufactures and winds the metal ribbon (ribbon 11). Therefore, the metal ribbon winding system 100A according to this embodiment can shorten the process cycle time. Ideally, the metal ribbon winding system 100A according to this embodiment should be able to simultaneously complete the manufacture of the metal ribbon (ribbon 11) and the winding of the metal ribbon (ribbon 11).

[0060] Furthermore, the metal ribbon winding system 100A according to this embodiment scoops up, cuts, and grips the middle portion of the metal ribbon (ribbon 11) flying at the exit of the flight tube 23, and connects the leader 12 and the ribbon 11 for winding. The metal ribbon winding system 100A according to this embodiment makes the ribbon 11 production speed and the ribbon 11 winding speed approximately the same, so that only the minimum amount of ribbon 11 is stored in the stock area 24. Therefore, the metal ribbon winding system 100A according to this embodiment can reduce the stock area 24 (ribbon storage area).

[0061] Furthermore, the metal ribbon winding system 100A according to this embodiment can prepare for winding of the metal ribbon (ribbon 11) with a simple operation by not directly attaching the ribbon 11 to the winding roll 14. Therefore, the metal ribbon winding system 100A according to this embodiment can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0062] (2) As shown in FIG. 1, in the metal ribbon winding system 100A described in (1) above, the connecting means 41A is configured to connect the leader 12 and the ribbon 11 in a state where they are arranged in the vertical direction.

[0063] The metal ribbon winding system 100A according to this embodiment scoops up the ribbon 11 stored in the stock area 24 from bottom to top and cuts it. Then, the metal ribbon winding system 100A according to this embodiment easily connects the cut leading end 11b of the ribbon 11 to the remaining leading end 12b of the leader 12. The metal ribbon winding system 100A according to this embodiment can prepare the metal ribbon (ribbon 11) for winding with a simple operation, without directly attaching the ribbon 11 to the winding roll 14. Therefore, the metal ribbon winding system 100A according to this embodiment can improve the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0064] (3) From another perspective, the metal ribbon winding system 100A described in (1) above has the following features. That is, as shown in FIG. 1 , the metal ribbon winding system 100A according to this embodiment includes a flight tube 23 that causes the metal ribbon to fly, a winding roll rotation means 71, a cutting and gripping unit 30, a connecting means 41A, and a winding unit (winding motor 72). The flight tube 23 is a component that causes the metal ribbon to fly. The winding roll rotation means 71 is a component to which a winding roll 14 on which the metal ribbon remains is set. The cutting and gripping unit 30 is a component that cuts and grips the metal ribbon stored in the stock area 24. The connecting means 41A is a component that connects, as a ribbon 11, a leader 12 that is a portion to be connected of the metal ribbon remaining on the winding roll 14, and an arbitrary portion of the metal ribbon cut and gripped by the cutting and gripping unit 30. The winding unit (winding motor 72) is a component that rotates winding roll rotating means 71 to wind the ribbon 11 around the winding roll .

[0065] The metal ribbon winding system 100A according to this embodiment cuts and grips any portion flying from the flight tube 23 and connects it to the leader 12 as the ribbon 11. The metal ribbon winding system 100A according to this embodiment simultaneously performs the production of the metal ribbon (ribbon 11) and the winding of the metal ribbon (ribbon 11) in parallel. Therefore, the metal ribbon winding system 100A according to this embodiment can shorten the process cycle time. Furthermore, the metal ribbon winding system 100A according to this embodiment can minimize the amount of ribbon 11 stored in the stock area 24 by making the production speed of the ribbon 11 and the winding speed of the ribbon 11 approximately the same. Therefore, the metal ribbon winding system 100A according to this embodiment can reduce the size of the stock area 24 (ribbon storage area). Furthermore, the metal ribbon winding system 100A according to this embodiment can prepare the metal ribbon (ribbon 11) for winding by a simple operation, without directly attaching the ribbon 11 to the winding roll 14. Therefore, the metal strip winding system 100A according to this embodiment can improve the safety and workability of winding the metal strip (ribbon 11) around the winding roll .

[0066] (4) In the metal ribbon winding system 100A described in (3) above, the cutting gripper 30 has a ribbon cutter 51Aa (cutter) that cuts the ribbon 11, and a stopper 31A that holds the ribbon 11 in a state where the ribbon 11 is arranged so as to surround the ribbon cutter 51Aa. The metal ribbon winding system 100A having this configuration cuts the ribbon 11 by moving the ribbon cutter 51Aa in a state where the ribbon 11 is held by the stopper 31A.

[0067] The metal ribbon winding system 100A having this configuration can cut the ribbon 11 by moving the ribbon cutter 51Aa while the ribbon 11 is held by the stopper 31A. The metal ribbon winding system 100A having this configuration can easily wind the ribbon 11 stored in the stock area 24 around the winding roll 14, thereby improving the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0068] (5) In the metal ribbon winding system 100A described in (4) above, the connecting means 41A is configured to connect the leader 12 and the ribbon 11 in a state where they are arranged in the vertical direction. The cutting and holding unit 30 is configured to cut the ribbon 11 near the connecting means 41A and to place one end (cut tip 11b) of the cut ribbon 11 near the remaining tip 12b of the leader 12.

[0069] The metal ribbon winding system 100A having this configuration can easily connect the cut leading end 11b of the cut ribbon 11 to the remaining leading end 12b of the leader 12. The metal ribbon winding system 100A having this configuration can easily wind the ribbon 11 stored in the stock area 24 around the winding roll 14, thereby improving the safety and workability of winding the metal ribbon (ribbon 11) around the winding roll 14.

[0070] As described above, the metal ribbon winding system 100A according to the first embodiment can shorten the process cycle time.

[0071] [Second embodiment] The metal ribbon winding system 100A (FIGS. 1 and 3) according to the first embodiment is configured to scoop up and cut the ribbon 11 from bottom to top. In contrast, the second embodiment provides a metal ribbon winding system 100B (FIGS. 7 and 8) configured to move the ribbon 11 in the front-to-rear direction (from upstream to downstream) and cut it.

[0072] The configuration of a metal ribbon winding system 100B according to the second embodiment will be described below with reference to Fig. 7 and Fig. 8. Fig. 7 is a configuration diagram of the metal ribbon winding system 100B according to the second embodiment. Fig. 8 is a configuration diagram of the vicinity of a connection means 41B of the metal ribbon winding system 100B.

[0073] As shown in FIG. 7, the metal ribbon winding system 100B according to the second embodiment differs from the metal ribbon winding system 100A (FIG. 1) according to the first embodiment in the following points. (1) The ribbon cutting jig 30B is provided instead of the ribbon cutting jig 30A. (2) The reader connecting jig 40B is provided instead of the reader connecting jig 40A. (3) The ribbon connection robot 50B is provided instead of the ribbon connection robot 50A.

[0074] 7, the ribbon splicing robot 50B of the metal strip winding system 100B is disposed forward (upstream) of the stock area 24. However, the ribbon splicing robot 50B of the metal strip winding system 100B may be disposed in the same position (FIG. 2) as the ribbon splicing robot 50A of the metal strip winding system 100A of the first embodiment. In other words, the arrangement of the components of the metal strip winding system 100B as viewed from above can be the same as the arrangement of the components of the metal strip winding system 100A of the first embodiment (FIG. 2).

[0075] 8, ribbon cutting jig 30B of metal ribbon winding system 100B includes stopper 31B that fixes ribbon 11 and air nozzle 32 that discharges air 33 (FIG. 9B). Stopper 31B includes fixed shaft 31Ba and pressure shaft 31Bb that sandwiches ribbon 11 between stopper 31B and fixed shaft 31Ba. Stopper 31B also includes air cylinder 31Bc that moves pressure shaft 31Bb in the direction of arrow A31B (approaching or moving away from fixed shaft 31Ba), and ribbon positioning block 31Bd that determines the position of ribbon 11 in the width direction.

[0076] Furthermore, the leader connecting jig 40B of the metal ribbon winding system 100B includes connecting means 41B. The connecting means 41B has a fixed plate 41Ba that supports the remaining tip portion 12b of the leader 12, and a pressure pad 41Bb that sandwiches the cut tip portion 11b of the ribbon 11 and the remaining tip portion 12b of the leader 12 between the fixed plate 41Ba and the pressure pad 41Bb. An adhesive tape 13 is adhered to the remaining tip portion 12b of the leader 12. Therefore, when the connecting means 41B sandwiches the cut tip portion 11b of the ribbon 11 and the remaining tip portion 12b of the leader 12 between the fixed plate 41Ba and the pressure pad 41Bb, the cut tip portion 11b of the ribbon 11 and the remaining tip portion 12b of the leader 12 are connected by the adhesive tape 13. The connecting means 41B also has an air cylinder 41Bc that moves the pressure pad 41Bb in the direction of the arrow A41B (the direction approaching or moving away from the fixed plate 41Ba).

[0077] The ribbon splicing robot 50B of the metal ribbon winding system 100B also includes a robot hand 51B. The robot hand 51B has a blade-shaped fixed finger 51Ba and a pressure finger 51Bb that applies pressure to the ribbon 11. The robot hand 51B also has an air cylinder 51Bc that moves the pressure finger 51Bb in the direction of arrow A51B (up and down in the illustrated example).

[0078] Figure 9A shows the configuration of air nozzle 32, stopper 31B, and robot hand 51B as seen from the rear. Figure 9B shows the configuration of air nozzle 32, stopper 31B, and robot hand 51B as seen from the right. Air nozzle 32 is positioned above stopper 31B and sprays air 33 at any timing.

[0079] 4, the metal ribbon winding system 100B according to the second embodiment operates in the same manner as the metal ribbon winding system 100A according to the first embodiment. At that time, in step S130, the metal ribbon winding system 100B operates the ribbon cutting jig 30B and the robot hand 51B, for example, as shown in FIGS. 10A to 10H.

[0080] Fig. 10A shows a stable quality state of ribbon 11. In the example shown in Fig. 10A, metal ribbon winding system 100B scoops up ribbon 11 flying from flight tube 23 with robot hand 51B.

[0081] Fig. 10B shows the robot hand 51B in an elevated state. In the example shown in Fig. 10B, the metal ribbon winding system 100B moves the robot hand 51B upward so that it passes between the fixed shaft 31Ba and the pressure shaft 31Bb of the ribbon cutting jig 30B. As a result, the metal ribbon winding system 100B lifts the ribbon 11 with the robot hand 51B and positions the ribbon 11 so that it passes upward from between the fixed shaft 31Ba and the pressure shaft 31Bb of the ribbon cutting jig 30B.

[0082] Fig. 10C shows a fixed state of ribbon 11. In the example shown in Fig. 10C, metal ribbon winding system 100B moves pressure shaft 31Bb toward fixed shaft 31Ba. As a result, metal ribbon winding system 100B sandwiches ribbon 11 between pressure shaft 31Bb and fixed shaft 31Ba, thereby fixing ribbon 11.

[0083] Fig. 10D shows a state in which ribbon 11 is cut. In the example shown in Fig. 10D, metal ribbon winding system 100B raises robot hand 51B, thereby cutting ribbon 11 with fixed fingers 51Ba of robot hand 51B.

[0084] Fig. 10E shows the winding state of ribbon 11. In the example shown in Fig. 10E, metal ribbon winding system 100B discharges air 33 from air nozzle 32 to wind cut tip 11b of ribbon 11 around pressure finger 51Bb of robot hand 51B.

[0085] FIG. 10F shows a state in which the ribbon 11 is held. In the example shown in FIG. 10F, the metal ribbon winding system 100B raises the pressure finger 51Bb of the robot hand 51B. As a result, the metal ribbon winding system 100B sandwiches the ribbon 11 between the fixed finger 51Ba and the pressure finger 51Bb of the robot hand 51B, thereby fixing the ribbon 11. The ribbon 11 sandwiched between the fixed finger 51Ba and the pressure finger 51Bb is used for winding around the winding roll 14. Hereinafter, the ribbon 11 sandwiched between the fixed finger 51Ba and the pressure finger 51Bb is referred to as the "used ribbon 11c ( FIG. 10G )." Furthermore, the ribbon 11 that is not sandwiched between the fixed finger 51Ba and the pressure finger 51Bb is not used for winding around the winding roll 14. The ribbon 11 that is not sandwiched between the fixed finger 51Ba and the pressure finger 51Bb is referred to as an "unused ribbon 11d (FIG. 10G)."

[0086] 10G shows the released state of the unused ribbon 11d. In the example shown in FIG. 10G, the metal ribbon winding system 100B moves the pressure shaft 31Bb in a direction away from the fixed shaft 31Ba. As a result, the metal ribbon winding system 100B releases the unused ribbon 11d that is not used for bonding to the leader 12. The released unused ribbon 11d falls and enters the stacker area 24.

[0087] Fig. 10H shows the state in which the used ribbon 11c is removed. In the example shown in Fig. 10H, the metal ribbon winding system 100B moves the robot hand 51B downward so that it passes between the fixed shaft 31Ba and the pressure shaft 31Bb of the ribbon cutting jig 30B. As a result, the metal ribbon winding system 100B lifts up the used ribbon 11c with the robot hand 51B and removes the used ribbon 11c from between the fixed shaft 31Ba and the pressure shaft 31Bb of the ribbon cutting jig 30B.

[0088] Thereafter, the metal ribbon winding system 100B performs the process of step S140 shown in FIG. 4 to connect the leader 12 and the ribbon 11 (used ribbon 11c).

[0089] Then, the metal strip winding system 100B winds the metal strip (ribbon 11) around the winding roll 14 by performing the process of step S150 shown in FIG.

[0090] The connecting means 41B of the metal ribbon winding system 100B is configured to connect the leader 12 and the ribbon 11 in a state in which they are arranged horizontally. The cutting and holding unit 30 is configured to cut the ribbon 11 near the connecting means 41B, and to place one end (cut tip 11b) of the cut ribbon 11 on the remaining tip 12b of the leader 12 and connect them.

[0091] The metal ribbon winding system 100B of this embodiment feeds the ribbon 11 approximately horizontally from the connection means 41B toward the winding machine 70, which may reduce the load on the ribbon 11 and make it easier to feed the ribbon 11.

[0092] As described above, the metal ribbon winding system 100B according to the second embodiment can shorten the process cycle time, similar to the metal ribbon winding system 100A according to the first embodiment.

[0093] The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention. [Explanation of symbols]
