Background Art
[0002] Conventionally, a winding (enameled wire) in which an insulating film is formed on the surface of a conductor made of a metal wire is known. The winding is widely used as a coil of various electrical devices. Examples of electrical devices using the coil include a reactor, an in-vehicle motor, and the like.

On the other hand, a high-efficiency motor is composed of segment coils. One coil material (also referred to as a linear material) before being bent, which is the material of this segment coil, is manufactured, for example, by feeding an insulated film flat conductor by a feeding device while performing a coating peeling process on a part of the conductor a plurality of times and cutting it to a required length at the feeding destination.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, in the manufacturing apparatus as described above, generally, since a plurality of processing apparatuses for processing the winding are fixed, in order to manufacture a plurality of types of linear materials having different lengths, first, a plurality of the first type of linear materials are manufactured, and then, after changing the position of the processing apparatus and the cutting position, it is necessary to manufacture the second type of linear material having a length different from that of the first type of linear material. For this reason, when manufacturing linear materials having different lengths, the manufacturing process is complicated, and the equipment must be temporarily stopped when switching the linear materials to be manufactured, and there is a problem that linear materials having different lengths cannot be manufactured efficiently in sequence.
Means for Solving the Problems
[0006] The present disclosure can be realized in the following forms. According to one embodiment of the present disclosure, there is provided a linear material manufacturing apparatus that feeds out a wound wire in the conveying direction for each conveying cycle, performs processing on the wire, and then cuts it at the conveying destination to manufacture a plurality of types of linear materials having different lengths in a stacked manner. This apparatus includes a pay-out device that pays out the wire in the conveying direction, a device that performs processing on the wire, the processing device being movable in a position along the conveying direction for each conveying cycle, a device that conveys the wire in the conveying direction for each conveying cycle, the conveying device being provided on the downstream side of the processing device in the conveying direction and being movable in a position along the conveying direction for each conveying cycle, a cutting device that is fixed at a predetermined position and cuts the wire processed by the plurality of processing devices, and a control device that calculates the position of each conveying cycle of the processing device and the conveying device using the length information of the linear material, and controls the positions of the plurality of processing devices and the conveying device for each conveying cycle. When calculating the position of a calculation target device, which is the processing device or the conveying device for which the position for each conveying cycle is to be calculated, the control device calculates the position of the calculation target device by summing up the lengths of the linear material intervening between the cutting device and the calculation target device. A plurality of data storage boxes are provided corresponding to a plurality of processes including a next processing step, which is a step before the processing by the processing device and is a step toward the processing device, the processing step by the processing device, and the conveying step by the conveying device. The data storage boxes store line length-related information, which is information related to the length of the linear material to be processed in each process. The control device calculates the position of the calculation target device using the stored line length-related information. Each time each conveying cycle ends, the control device executes a transfer process of transferring the line length-related information stored in the data storage box set for the conveying cycle to the data storage box set for the next conveying cycle. When executing the transfer process, the control device transfers the line length-related information stored in the data storage box corresponding to each process in the conveying cycle to the data storage box corresponding to the next process for the process in the next conveying cycle. In the next conveying cycle, using the line length-related information transferred to the data storage box,Calculate the position of the device to be calculated in the next conveying cycle. A mark indicating a defective part is provided on the wire rod. The wire-shaped material manufacturing apparatus further includes a detection unit that detects the defective part between the unwinding device and a first processing device that is the processing device closest to the unwinding device. When the tip of the mark in the conveying direction is detected by the detection unit, the control device calculates, for each conveying cycle, the distance from the first processing device to the tip, and compares the distance with the wire length-related information stored in the data storage box corresponding to the next processing step. When the distance becomes shorter than the length of the wire-shaped material in the next processing step, interrupt the data storage box corresponding to the next processing step with discard wire type information, which means it is a wire type to be discarded as the wire length-related information.
[0007] (1) According to one aspect of the present disclosure, a linear material manufacturing apparatus is provided. This linear material manufacturing apparatus is a linear material manufacturing apparatus that feeds out a wound wire in the conveying direction for each conveying cycle, performs processing on the wire, and then cuts it at the conveying destination to sequentially manufacture a plurality of types of linear materials having different lengths. The linear material manufacturing apparatus includes a pay-out device that pays out the wire in the conveying direction, a device that performs processing on the wire, the processing device being movable in a position along the conveying direction for each conveying cycle, a device that conveys the wire in the conveying direction for each conveying cycle, the conveying device being provided on the downstream side of the processing device in the conveying direction and being movable in a position along the conveying direction for each conveying cycle, a cutting device that is fixed at a predetermined position and cuts the wire processed by the plurality of processing devices, and a control device that calculates the position of the processing device and the conveying device for each conveying cycle using information on the length of the linear material and controls the positions of the plurality of processing devices and the conveying device for each conveying cycle. According to the linear material manufacturing apparatus of this embodiment, by the control device, for each conveying cycle, the positions of the processing device and the conveying device for each conveying cycle are calculated using the information on the length of the linear material, and the position is controlled for each conveying cycle. Therefore, while sequentially paying out the wound wire in the conveying direction by the pay-out device, the processed wire is cut by the cutting device, so that linear materials with different lengths can be continuously produced in a standing order. That is, productivity can be improved. (2) In the above embodiment, when the control device calculates the position of the calculation target device, which is the processing device or the conveying device for which the position for each conveying cycle is to be calculated, the control device may calculate the position of the calculation target device by adding up the lengths of the linear materials intervening between the cutting device and the calculation target device. According to the linear material manufacturing apparatus of this embodiment, the position of the calculation target device can be easily calculated by adding up the wire type information of the linear materials intervening between the cutting device and the calculation target device. (3) In the above embodiment, the control device stores, in a plurality of data storage boxes provided corresponding to a plurality of processes including the next processing process, which is a process before the processing by the processing device and is a process going toward the processing device, the processing process by the processing device, and the conveying process by the conveying device, the wire length related information, which is information related to the length of the linear material to be processed in each process. The control device calculates the position of the calculation target device using the stored wire length related information. Each time each conveying cycle ends, the control device executes a transfer process of transferring the wire length related information stored in the data storage box set for the conveying cycle to the data storage box set for the next conveying cycle. When executing the transfer process, the wire length related information stored in the data storage box corresponding to each process in the conveying cycle is transferred to the data storage box corresponding to the next process for the process in the next conveying cycle. In the next conveying cycle, the position of the calculation target device in the next conveying cycle may be calculated using the wire length related information transferred to the data storage box. According to the linear material manufacturing apparatus of this embodiment, the control device stores line length related information, which is information related to the length of the linear material to be processed in each process, in a plurality of data storage boxes provided corresponding to each process. Then, by the transfer process executed every time the transfer cycle ends, the line length related information stored in the data storage box corresponding to each process in the transfer cycle is transferred to the data storage box corresponding to the next process for the next process in the next transfer cycle. Therefore, by using the transferred line length related information in the next transfer cycle, the position of the calculation target device can be easily calculated. (4) In the above embodiment, a plurality of the processing devices may be provided, and a plurality of the processing steps may be executed on the wire by the plurality of the processing devices. According to the linear material manufacturing apparatus of this embodiment, since a plurality of processing steps can be executed on the wire by a plurality of processing devices, a linear material that requires a plurality of processes before cutting can be manufactured. (5) In the above embodiment, a mark indicating a defective portion is provided on the wire, and a detection unit for detecting the defective portion is further provided between the unwinding device and the first processing device, which is the processing device closest to the unwinding device. When the control device detects the leading end of the mark in the transport direction by the detection unit, the control device calculates the distance from the first processing device to the leading end for each transport cycle, and compares the distance with the line length related information stored in the data storage box corresponding to the next processing step. When the distance is shorter than the length of the linear material in the next processing step, the control device may interrupt the data storage box corresponding to the next processing step with discard line type information indicating that it is the line type to be discarded as the line length related information. According to the linear material manufacturing apparatus of this embodiment, a mark indicating a defective part of the wire is detected by the detection unit, and the control unit calculates the distance from the first processing device to the tip of the mark, and compares the distance with the wire type information stored in the data storage box corresponding to the next processing step. Then, when the distance becomes shorter than the length of the wire type information of the next processing step, the waste wire type information is interrupt-processed. By performing the process based on the detection of the tip of the mark in this way, it becomes possible to interrupt the waste wire type information during in-line production. (6) In the above embodiment, when the control device detects the end of the mark in the transport direction by the detection unit and the end is transported downstream in the transport direction from the first processing device, the linear material to be processed next in the first processing device is arranged along the in-line order. The wire length related information along the in-line order may be stored in the data storage box corresponding to the next processing step. According to the linear material manufacturing apparatus of this embodiment, by performing the process based on the detection of the end of the mark, it is possible to return to the in-line wire type information. By performing the process based on the detection of the tip and the end of the mark, the amount of good products included in the winding to be discarded can be minimized without stopping the equipment. The discarded part can be minimized. (7) In the above embodiment, the wire may be an insulated coated copper wire having a rectangular cross-section that is a material for a segment coil, and the processing device may be a peeling device that peels the insulated coating. According to the linear material manufacturing apparatus of this embodiment, by performing peeling processing and cutting on the insulated coated copper wire having a rectangular cross-section that is a material for a segment coil, it is possible to efficiently manufacture a linear material in an in-line manner.

Embodiments for Carrying Out the Invention
[0009] A. First Embodiment: A1. Overall Configuration of the Linear Material Manufacturing Apparatus 1: FIG. 1 is a schematic diagram showing the overall schematic configuration of the linear material manufacturing apparatus 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the linear material manufacturing apparatus 1 includes a pay - out device 11, a straightening device 12, a processing unit 13, a conveying unit 14, a cutting device 15, a loading device 16, a stocker 17, and a control device 30 (see FIG. 2).
[0010] The linear material manufacturing apparatus 1 of the first embodiment feeds out the flat copper wire W (hereinafter, also simply referred to as "angled wire W") wound around the drum 6 in predetermined amounts, performs a plurality of peeling processes, and then cuts it to a predetermined length, thereby manufacturing a plurality of types of linear materials having different lengths to be used as materials for segment coils. The angled wire W is an insulated coated copper wire having a rectangular cross - section and corresponds to the "wire rod". The segment coil is used, for example, in a high - efficiency motor as a drive motor for a vehicle. The coil for the high - efficiency motor is made by assembling segment coils in sequence.
[0011] The flat copper wire W serving as the material for the segment coil is manufactured by stretching and softening the fed - out wire rod to form a conductor and then forming an insulating coating on the surface of the conductor. The flat conductor is arranged in the pay - out device 11 in a state of being wound around the drum 6. Hereinafter, the flat copper wire W wound around the drum 6 is simply referred to as the "wound wire".
[0012] The pay - out device 11 is a device that feeds out the wound wire from the drum 6 around which the wound wire is wound in the conveying direction. The straightening device 12 is a device that straightens the winding kink of the wound wire. The processing unit 13 is a device that performs peeling processing on the insulating coating of the wound wire and is composed of a first processing device 21, a second processing device 22, a third processing device 23, a fourth processing device 24, and a fifth processing device 25.
[0013] As the processing devices 21 to 25, for example, there is a peeling device unit having a punch (not shown), a die, and a servo motor as a driving device. A cutting edge is provided at the tip of the punch, and a receiving edge is provided on the die. The punch can move relative to the die, such as moving up and down, along with the rotation of an eccentric cam driven by the servo motor, for example, as the eccentric cam rotates. The punch is driven with respect to the angular line W whose posture is maintained, and the cutting edge punches a predetermined portion of the angular line W, thereby peeling the insulating film at the predetermined portion. Necessary peeling processes (Processes 1 to 5) are sequentially performed by each of the processing devices 21 to 25.
[0014] In this embodiment, the rear end of an arbitrary (n - 1)th linear material and the front end of the nth linear material are processed by one peeling device unit. After performing Processes 1 to 5 on the angular line W, the linear material is cut out by cutting the center of the processed portion with the cutting device 15.
[0015] Specifically, Processes 1 to 5 by the processing devices 21 to 25 correspond to, for example, peeling processes on the upper and lower surfaces and the left and right side surfaces at a predetermined portion of the angular line W, and chamfering processes on the corners of the peeled portions. In this embodiment, five processing devices 21 to 25 are provided. However, since the processes and the number of processes required vary depending on the product, the number of installed processing devices is not limited to five and is appropriately set according to the product.
[0016] The conveying unit 14 is a device that sequentially conveys the angular line W to the next processing device. The conveying unit 14 includes a first conveying device 26 and a second conveying device 27. Each of the conveying devices 26 and 27 has a chuck mechanism capable of gripping the angular line W, and can perform an operation of conveying the angular line W gripped by the chuck mechanism in the conveying direction and a return operation of returning to the chucking position. Each of the conveying devices 26 and 27 alternately performs an operation of gripping and conveying the angular line W. That is, when the angular line W is gripped by the chuck mechanism of one conveying device and sent in the conveying direction, the chuck mechanism of the other conveying device at the conveying destination is open, and the angular line W is conveyed alternately by swapping the front and rear of the conveying devices 26 and 27 in order.
[0017] Each of the processing devices 21 to 25 and each of the transfer devices 26, 27 is self-propelled and can move to a position parallel to the transfer line in the direction in which the angular line W extends in the transfer direction for each transfer cycle of the angular line W. As a drive mechanism for self-propelling each device, for example, a rack and pinion mechanism driven by a servo motor, a linear actuator mechanism having an electromagnet, or the like can be adopted. The calculation of the position for each transfer cycle of each of the processing devices 21 to 25 and each of the transfer devices 26, 27 and the movement control to the calculated position (hereinafter simply referred to as the "calculated position") are performed by the control device 30. Details of such calculation of the calculated position and control of each device to the calculated position will be described later in the following linear material manufacturing method.
[0018] The cutting device 15 cuts the angular line W processed by the plurality of processing devices 21 to 25 into a predetermined product length. The cutting device 15 is, for example, a cutter that cuts the angular line W and separates it from the winding. Unlike the above-described processing devices 21 to 25 and transfer devices 26, 27, the cutting device 15 is fixed at a predetermined position. The loading device 16 is a device that loads the angular line W cut by the cutting device 15 into the stocker 17. The stocker 17 temporarily stores the cut angular line W before transferring it to the next bending process. The stocker 17 has a plurality of stepped portions associated with a bending process station (not shown) that is conveyed next after peeling and cutting. The angular line W cut by the cutting device 15 is appropriately distributed and loaded onto the stepped portions of the stocker 17 by the loading device 16.
[0019] A2. System configuration of the linear material manufacturing apparatus 1: FIG. 2 is a control block diagram showing the system configuration of the linear material manufacturing apparatus 1. As shown in FIG. 2, a control device 30 included in the linear material manufacturing apparatus 1 is communicably connected to various processing mechanism units 40 including the various processing mechanisms (unwinding device 11, straightening device 12, each processing device 21 to 25, conveying devices 26 and 27, cutting devices 15, loading device 16, stocker 17) described in detail above. The control device 30 includes a CPU 31 and a storage unit 32. The control device 30 is a microcomputer including a ROM, a RAM, and other input / output ports (not shown), and controls the entire linear material manufacturing apparatus 1. The control device 30 is connected to a production management system 50, and receives, as an instruction from the production management system 50, for example, the vehicle type of a vehicle equipped with a motor using the linear material and the order of the vehicle types to be produced.
[0020] The CPU 31 functions as an operation control unit 33, a wire type information transmission / reception unit 34, a position calculation unit 35, and a processing unit 36 by expanding various programs stored in the storage unit 32. The operation control unit 33 controls the movement operations and operation operations of the various processing mechanism units 40. The wire type information transmission / reception unit 34 transmits and receives wire type information. Here, the "wire type information" is an example of "wire length related information" related to the length of the linear material to be processed, and includes information on the length of the linear material. The position calculation unit 35 calculates the positions for each conveyance cycle of each of the processing devices 21 to 25 and the conveyance devices 26 and 27. The processing unit 36 executes various arithmetic processes and various determination processes associated with the arithmetic process results, which will be described later.
[0021] A3. Method for manufacturing a linear material by the linear material manufacturing apparatus 1: FIG. 3 is a flowchart showing the processing steps of the linear material manufacturing method executed by the control device 30 of the linear material manufacturing apparatus 1 described in detail above. As shown in FIG. 3, the linear material manufacturing method includes a wire type information reading step (S10), a position calculation step (S20), a product work loading step (S30), a peeling process step (S40), a cutting step (S50), and a wire type information transfer step (S60). The flowchart shown in FIG. 3 is executed once for each conveyance cycle. In the example of the present embodiment, eight product works A, B, C, D, E, F, G, and H having different lengths are manufactured in order, in the order of product works A to H, by stacking them upright. The product works A to H are linear materials that are materials for segment coils that constitute motors for vehicles of any vehicle type.
[0022] In the wire type information reading step (S10), the wire type information of the products handled by each processing device 21 to 25 and each conveyance device 26, 27 is read by the wire type information transmission / reception unit 34 from a data storage box Db (hereinafter, also simply referred to as "storage box Db"). FIG. 4 is a diagram showing, in table T1, the storage form of the wire type information read for each process for each conveyance cycle. For each conveyance cycle, wire type information is read and assigned to the data storage box Db corresponding to each process. As shown in FIG. 4, the wire type information of any one of the products manufactured in order is stored in the storage box Db corresponding to each process.
[0023] The storage box Db is provided corresponding to each of the steps of "next processing", "processing 1", "processing 2", "processing 3", "processing 4", "processing 5", "conveyance", "before cutting", and "after cutting". These steps are steps that are executed in order in the conveyance direction. The "next processing" step is a step before the processing by the first processing device 21 and is a step toward the first processing device 21. The storage box Db for "next processing" is the storage box Db corresponding to the section from the virtual boundary line S (see FIG. 1) located between the unwinding device 11 and the first processing device 21 to the first processing device 21, and stores data for preparing in advance the wire type information to be passed to the first processing device 21 next.
[0024] In the storage box Db for "Processing 1", the wire type information of the product processed by the first processing device 21 in the corresponding cycle is stored. In the storage box Db for "Processing 2", the wire type information of the product processed by the second processing device 22 in the corresponding cycle is stored. In the storage box Db for "Processing 3", the wire type information of the product processed by the third processing device 23 in the corresponding cycle is stored. In the storage box Db for "Processing 4", the wire type information of the product processed by the fourth processing device 24 in the corresponding cycle is stored. In the storage box Db for "Processing 5", the wire type information of the product processed by the fifth processing device 25 in the corresponding cycle is stored.
[0025] In the storage box Db for "Transportation", the wire type information of the product transported in the transportation process by the transportation unit 14 in the corresponding cycle is stored. The "Before Cutting" process is the process where the linear material is at the position where it will be cut in the next transportation cycle. The storage box Db for "Before Cutting" is the corresponding storage box Db between the transportation unit 14 and the cutting device 15, and the data to be passed to the cutting device 15 next is stored. The "After Cutting" process is the process of passing the cut linear material to the stocker 17. The storage box Db for "After Cutting" is the corresponding storage box Db between the cutting device 15 and the stocker 17 in the corresponding cycle, and the information of the product cut from the winding is stored. The information in the storage box Db for "After Cutting" is the wire type information of the product workpiece (any one of A to G) after the peeling and cutting processes by the linear material manufacturing device 1.
[0026] In the position calculation step (S20), the positions of the processing devices 21 to 25 and the transportation devices 26, 27 are calculated by the position calculation unit 35. Specifically, the positions of the processing devices 21 to 25 and the transportation devices 26, 27 at the nth cycle are calculated by summing up the wire type information of the linear materials intervening between the fixed cutting device 15 and the calculation target device to be calculated, with the position of the fixed cutting device 15 as the reference. Before being cut, although the linear materials are not individually separated, the state where the linear materials are continuous can be grasped, and it can be said that these continuous linear materials intervene between the cutting device 15 and the calculation target device.
[0027] Here, let the wire type information of product workpiece A be La, the wire type information of product workpiece B be Lb, the wire type information of product workpiece C be Lc, the wire type information of product workpiece D be Ld, the wire type information of product workpiece E be Le, the wire type information of product workpiece F be Lf, the wire type information of product workpiece G be Lg, and the wire type information of product workpiece H be Lh. Hereinafter, the "wire type information of product workpiece" is also simply referred to as "wire type length". Also, each processing device 21 to 25 and each transfer device 26, 27 correspond to the "device to be calculated". Specifically, the positions of each processing device 21 to 25 and each transfer device 26, 27 at the nth cycle are calculated by the following formula.
[0028] Position of the second transfer device 27: L7 = Lb Position of the first transfer device 26: L6 = Lb + Lc Position of the fifth processing device 25: L5 = Lb + Lc + Ld Position of the fourth processing device 24: L4 = Lb + Lc + Ld + Le Position of the third processing device 23: L3 = Lb + Lc + Ld + Le + Lf Position of the second processing device 22: L2 = Lb + Lc + Ld + Le + Lf + Lg Position of the first processing device 21: L1 = Lb + Lc + Ld + Le + Lf + Lg + Lh
[0029] In the product workpiece loading process (S30), the cut workpieces A to H are loaded into the stocker 17 by the loading device 16. This position calculation process (S20) and the product workpiece loading process (S30) are executed in parallel and almost simultaneously.
[0030] In the peeling process (S40), predetermined processing is performed by each of the processing devices 21 to 25 that have moved to the positions calculated in S20. In the cutting process (S50), the angular line W is cut from the winding by the cutting device 15. The peeling process (S40) and the cutting process (S50) are executed in parallel and almost simultaneously. In the wire type information transfer process (S60), the wire type information of the product targeted in the current transport cycle is transferred to the next process by the wire type information transceiver 34. In the table T1 of FIG. 4, the diagonal arrow is an image of the state of transferring the wire type information to the next process. The wire type information transfer process (S60) corresponds to the transfer process. Thus, this processing routine ends.
[0031] Through the above processing, as shown in FIG. 4, in the nth cycle, the product workpiece A is completed, in the (n + 1)th cycle, the product workpiece B is completed, and in the (n + 2)th cycle, the product workpiece C is completed. Similarly hereinafter, for each transport cycle, products are manufactured in order, in the order of product workpieces D, E, F, G, ···.
[0032] (Effect) According to the linear material manufacturing apparatus 1 and the linear material manufacturing method of the first embodiment, based on the wire type information read in the wire type information reading process (S10), the positions of each of the processing devices 21 to 25 and each of the transport devices 26, 27 are calculated in the position calculation process (S20). Then, at the position corresponding to that cycle (for example, the nth cycle), processing by the processing unit 13 and transport by the transport unit 14 are executed. Then, every time the processing and transport processing ends, the wire type information is transferred to the next process in S60. Then, in the next transport cycle (for example, the (n + 1)th cycle), the reading of the wire type information (S10) and the positions of each of the processing devices 21 to 25 and each of the transport devices 26, 27 are recalculated.
[0033] By repeating the above process, product workpieces A to H with different lengths can be continuously produced in sequence. Further, various product workpieces manufactured by the linear material manufacturing apparatus 1 are then bent and further welded in a state where the product workpieces are arranged in order. For example, when manufacturing a plurality of product workpieces A and then manufacturing a plurality of product workpieces B, when sending to the subsequent process as described above, an operation of rearranging the products was necessary. In that regard, according to the first embodiment, since product workpieces A to H with different lengths are manufactured in sequence, the operation of rearranging is unnecessary and efficient.
[0034] B. Second Embodiment: B1. Overall Configuration: Next, a second embodiment of the present disclosure will be described with reference to FIGS. 5 to 10. In the second embodiment and each of the following embodiments, since the overall configuration of the linear material manufacturing apparatus 2 and the schematic configuration of the control apparatus 3 (FIG. 2) are substantially the same as those of the first embodiment, the same reference numerals are assigned to substantially the same parts and the description thereof is omitted. FIGS. 5 and 6 are schematic diagrams showing the overall schematic configuration of the linear material manufacturing apparatus 2 in the second embodiment of the present disclosure. The linear material manufacturing apparatus 2 of the second embodiment is different from the linear material manufacturing apparatus 1 of the first embodiment in that it further includes a mark detection sensor 28 for detecting a defective part mark 41.
[0035] The winding (angle wire W) used in the second embodiment is provided with a defective part mark 41 indicating a defective part. The defective part mark 41 is a mark pre-attached to the defective part of the winding. The defective part is, for example, a pinhole, swelling or peeling of the coating, etc. The defective part mark 41 is colored over several millimeters before and after the defective part by a marking process at the defective part detected by the defective part inspection process.
[0036] As inspection methods for defective parts of the insulating film, in the case of swelling or peeling, for example, the surface of the winding is imaged with a CCD camera or the like, and the captured image is processed by an image processing device to detect the defect, or the film thickness of the insulating film formed on the surface of the winding is measured with a laser displacement meter to detect the defect. For pinholes, for example, it can be detected by measuring the insulation resistance using a withstand voltage tester (spark tester). As the marking process, for example, an inkjet printer is used to mark the defective part in black.
[0037] The mark detection sensor 28 is provided between the unwinding device 11 and the correction device 12. In this embodiment, the mark detection sensor 28 is a color sensor and reads the defective part mark 41 pre-attached to the winding. The mark detection sensor 28 corresponds to the "detection unit".
[0038] FIG. 5 shows the state when the tip 42 of the defective part mark 41 is detected. FIG. 6 shows the state when the end 43 of the defective part mark 41 is detected. In FIGS. 5 and 6, "when detected" refers not to the moment when the mark detection sensor 28 described later detects the defective part mark 41 during winding conveyance, but to the state at the time when the defective part mark 41 is detected during winding conveyance and the conveyance cycle that detected the mark 41 has ended and stopped.
[0039] In the second embodiment, while executing the same control as in the first embodiment (the flowchart shown in FIG. 3), the tip 42 and the end 43 of the defective part mark 41 are detected by the mark detection sensor 28. Further, since the part of the defective part mark 41 cannot be included in the product, in the second embodiment, information meaning the discarded wire type is assigned to the corresponding part of the winding including the defective part mark 41. Also, for the subsequent part of the winding including the defective part mark 41, which is a part where the product can be manufactured, it is returned to the wire type information along the correct order and continuously manufactured. That is, for the winding having the defective part mark 41, the processing is skipped and only the minimum necessary winding is discarded. This will be described in detail below in conjunction with the flowchart.
[0040] B2. Detection of the tip 42 of the mark: FIG. 7 is a flowchart showing a processing procedure for detecting the tip of a mark, which is executed by the control device 30 of the linear material manufacturing apparatus 2 according to the second embodiment. This mark tip detection is executed together with the start of conveyance. As shown in FIG. 7, in S101, the processing unit 36 determines whether or not the tip 42 of the defective part mark 41 has been detected by the mark detection sensor 28. If the tip 42 of the defective part mark 41 is not detected (S101: NO), the process returns and this control routine is repeated.
[0041] If the tip 42 of the defective part mark 41 is detected (S101: YES), the process proceeds to S102, and the processing unit 36 calculates the distance L from the first processing device 21 (processing step 1) to the tip 42 of the mark 41. Next, in S103, the processing unit 36 determines whether or not the calculated distance L is smaller than the length of the product workpiece in the next processing. If the distance L is less than or equal to the length of the product workpiece in the next processing (S103: YES), the process proceeds to S104, and the waste wire type Z is interrupt-processed in the storage box Db for the next processing. On the other hand, in S103, if the distance L is longer than the length of the product workpiece in the next processing (S103: NO), the process returns to S102, and the calculation process of the distance L is repeated.
[0042] FIG. 8 is a diagram showing, in Table T21, the storage form of the wire type information read in each process for each conveyance cycle, and includes the cycle in which the mark tip 42 is detected. In this example, eight types of product workpieces A to H are manufactured in sequence, and an example is shown in which the mark tip 42 is detected in the nth cycle, and then the mark tip 42 reaches the next processing step in four cycles. As shown in FIG. 8, at the (n + 4)th cycle, the data that should originally be stored in the storage box Db for the next processing is "E", but the waste wire type Z is interrupt-processed. This is because at the next "(n + 5)" cycle, the defective part mark 41 will reach the first processing device 21.
[0043] In this way, the distance L is always calculated. When the defective part mark 41 cannot ensure the length of the product workpiece to be processed next, the discarded wire type Z, which is information to be discarded, is stored. Interrupt the discarded wire type Z until the mark end 43 passes, that is, until the mark end 43 reaches the first processing device 21.
[0044] [Calculation method of the distance L from the first processing device 21 (processing step 1) to the mark tip 42] Next, the calculation method of the distance L from the first processing device 21 (processing step 1) to the mark tip 42 will be described. The mark tip 42 is detected while the angular wire W is being conveyed. If the amount of movement from the moment of detection until the conveyance of the detected conveyance cycle ends is △L, then the distance Ln from the first processing device 21 to the mark tip 42 when n cycles of detecting the mark have ended is Ln = LS - L1 - △L which is represented by. (L1: distance from the cutting device 15 to the first processing device 21) Here, LS (see Fig. 5) is the distance from the cutting device 15 to the mark detection sensor 28 and is a fixed value.
[0045] The distance that the angular wire W is conveyed in each cycle is the length of the wire type cut out in the post-cutting process of the next conveyance cycle. That is, since the wire type length in the pre-cutting process of the previous conveyance cycle becomes the conveyance distance, if the wire type length before cutting is LI, then the distance L from the first processing device 21 to the mark tip 42 in the next cycle n+1 is L n+1 = Ln - LI = LS - L1 - △L - LI which is represented by.
[0046] At this time, if the length of each wire type is represented by the lowercase letter of the wire type (for example: La), then from the above table T21 (Fig. 8), the wire type in the pre-cutting process in n cycles is "B", so L n+1 = LS - L1 - △L - LI = LS - L1 - △L - Lb which is represented by. Compare this value with the wire type length (denoted as L0) in the next processing step. L n+1 = Ln - L1 - LI = LS - L1 - △L - Lb > L0 = La The comparison in the above formula corresponds to the process of S103. This is repeated every cycle. When the distance L from the first processing device 21 to the mark tip 42 becomes smaller than the wire type length L0 of the next processing step, that is, when L < L0, it means that the mark tip 42 has reached the next processing step. At this time, the wire type information in the next processing sequence is replaced with the discarded wire type.
[0047] B3. Detection of the mark end 43: Next, the detection of the mark end 43 will be described. FIG. 9 is a flowchart showing the processing procedure for detecting the mark end 43 executed by the control device 30 of the linear material manufacturing apparatus 2 according to the second embodiment. The flowchart shown in FIG. 9 is executed after the mark tip 42 is detected in the flowchart shown in FIG. 7. As shown in FIG. 9, in S111, the processing unit 36 determines whether the end 43 of the defective part mark 41 is detected by the mark detection sensor 28. If the end 43 of the defective part mark 41 is not detected (S111: NO), the process ends.
[0048] If the mark end 43 is detected (S111: YES), the process proceeds to S112, and the processing unit 36 calculates the distance L' from the first processing device 21 (processing step 1) to the mark end 43. Next, in S113, the processing unit 36 determines whether the calculated distance L' is smaller than 0. If the distance L' is smaller than 0 (S113: YES), the process proceeds to S114, and the wire type information along the sequence is stored in the storage box Db for the next processing. That is, it returns from the discarded wire type Z to the wire type information along the original sequence. On the other hand, in S113, if the distance L is 0 or more (S113: NO), the process returns to S112, and the calculation process of the distance L' is repeated.
[0049] FIG. 10 is a diagram showing in Table T22 the storage form of the wire type information read into the storage box Db of each process for each transport cycle, and is a diagram including the cycle in which the mark end 43 is detected. In this example, eight types of product workpieces A to H are manufactured in sequence, and the mark end 43 is detected in the m cycle, and then an example is shown in which the mark end 43 reaches the next processing step in 4 cycles. Further, the number of discarded pieces is set to 2. As shown in FIG. 10, at the m + 4 cycle, the wire type information "E" along the sequence is stored in the storage box Db for the next processing instead of the "discarded wire type Z". This is because at the "m + 4" cycle, the end 43 of the mark reaches the processing 1 step, so product workpieces can be manufactured from the next cycle.
[0050] [Calculation method of the distance L' from the first processing device 21 (processing step 1) to the mark end 43] Next, a method for calculating the distance L' (see FIG. 6) from the first processing device 21 (processing step 1) to the mark end 43 will be described. The end 43 of the defective part mark 41 is detected while the angular wire W is being transported. Let the movement amount from the moment of detection until the end of the transport in the transport cycle at the time of detection be ΔL'. Then, the distance L'm from the first processing device 21 to the mark end 43 when the m cycle in which the mark is detected ends is L'm = LS - L1 - ΔL' represented by.
[0051] Here, the distance that the angular wire W is transported in each transport cycle is the wire type length cut out in the post-cutting process of the next transport cycle. That is, it is the wire type length in the pre-cutting process of the previous transport cycle. Let the wire type length before cutting be L'I. Then, the distance L' from the first processing device 21 to the mark end 43 in the next transport cycle m+1 is L' m+1 = L'm - L'I = LS - L1 - ΔL' - L'I represented by. At this time, if the length of each wire type is represented by the lowercase letter of the wire type (for example, La), since the wire type in the pre-cutting process is "D" from the above Table T22 (FIG. 10), L' m+1=LS - L1 - ΔL’ - L’I = LS - L1 - ΔL’ - Ld It is represented by this value. Check whether this value is less than 0.
[0052] L’ m+1 = L’m - L’I = LS - L1 - ΔL’ - Ld < 0? The comparison in the above formula corresponds to the process of S113. This is repeated every cycle. When the distance L from the first processing device 21 to the mark end 43 becomes less than 0 (when L < 0), it means that the mark end 43 has reached the first processing step. At this time, the waste line type information for the next processing is returned to the in - line type information. That is, in the process described above, when the end 43 is detected by the mark detection sensor 28 and the end 43 is conveyed downstream in the conveyance direction from the first processing device 21 (S113: YES), the in - line length - related information is stored in the data storage box corresponding to the next processing step so that the linear material to be processed next in the first processing device 21 follows the in - line.
[0053] (Effect) According to the above - described second embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, by performing the process based on the detection of the mark tip 42 described in detail above, it is possible to interrupt the waste line type information during in - line production. Furthermore, by performing the process based on the detection of the mark end 43, it is possible to return to the in - line type information. Therefore, by performing the processes based on the detection of the mark tip 42 and the end 43, the amount of good products included in the waste corner line W can be minimized without stopping the equipment. The waste part can be minimized.
[0054] C. Third Embodiment: Next, the third embodiment of the present disclosure will be described with reference to FIGS. 11 to 13. FIG. 11 is a schematic diagram showing the overall schematic configuration of the linear material manufacturing apparatus 3 in the third embodiment of the present disclosure. The linear material manufacturing apparatus 3 is different from the linear material manufacturing apparatus 2 of the second embodiment in that it further includes a waste shooter 18 and automatically performs waste treatment of the waste wire type Z. Other configurations are the same. The waste shooter 18 is disposed downstream of the cutting device 15 in the conveying direction and stores the cut material corresponding to the waste wire type Z.
[0055] FIG. 12 is a flowchart showing the processing procedure of the linear material manufacturing method executed by the control device 30 of the linear material manufacturing apparatus 3. It is different from the flowchart shown in FIG. 3 in that the processing steps of S11 and S12 are added after S10. Other processes are the same. In the third embodiment, before the product work loading step (S30) by the loading device 16, in S11, the processing unit 36 determines whether the wire type of the work after cutting is the waste wire type Z. Note that the information on the waste wire type is transferred to the previous process as in the above embodiments.
[0056] And when the wire type of the work is the waste wire type Z (S11: YES), the process proceeds to S12, and the cut work is discharged by the loading device 16 to the waste shooter 18 instead of the stocker 17. On the other hand, when the wire type of the work after cutting is not the waste wire type Z (S11: NO), the process proceeds to S30, and the work after cutting is loaded by the loading device 16 into the stocker 17.
[0057] FIG. 13 is a diagram showing the storage form of the wire type information read in each process in Table T3 for each conveyance cycle. In the example shown in FIG. 13, eight types of product works A to H are manufactured in sequence, and an example is shown in which waste works reach the post-cutting process at the n-th cycle and the (n + 1)-th cycle. The number of waste pieces is two.
[0058] In the case of the example shown in Table T3 of FIG. 13, in the n-th cycle and the (n + 1)-th cycle, since the waste work is in the post-cutting process, the loading device 16 discharges the waste work to the waste shooter 18. From the (n + 2)-th cycle, since the product work (in-line type) is sent to the post-cutting process again, the loading device 16 starts loading the product work into the stocker 17.
[0059] (Effect) According to the above-described third embodiment, the same effects as those of the first embodiment can be achieved. Further, since the loading device 16 discharges the waste work to the waste shooter 18 based on the waste line type information, the waste work can be automatically discharged outside the machine. The operation of taking out the waste work accompanied by equipment stoppage becomes unnecessary, and the equipment operation can be improved and the productivity can be improved.
[0060] D. Fourth Embodiment: Next, a fourth embodiment of the present disclosure will be described with reference to FIGS. 14 and 15. FIG. 14 is a schematic diagram showing the overall schematic configuration of the linear material manufacturing apparatus 4 in the fourth embodiment of the present disclosure. The linear material manufacturing apparatus 4 is different from the linear material manufacturing apparatus 3 of the third embodiment in that the mark detection sensor 28 also functions as an end detection sensor for detecting the end 44 of the winding. The other configurations are the same. The end detection sensor detects the end 44 which is the end of the winding. In the third embodiment, when the end 44 of the winding is detected by the end detection sensor, the product is made until the remaining length becomes the limit length that can be discharged by the loading device 16 as waste work, and the waste treatment of the end copper wire is automatically performed without stopping the equipment. This will be described in detail below.
[0061] FIG. 15 is a diagram showing in Table T4 the storage form of wire type information read into each process for each conveyance cycle. In Table T4, the discarded wire type is designated as Z', the terminal discarded wire type as Z", and no wire type (after passing the terminal) as N. In order to pick up with the loading device 16 and discard it to the discard shooter 18, it is necessary to secure the minimum length enabling such an operation from the terminal 44 of the winding, and the discarded wire type, which is the rearmost part including the terminal 44, is the "terminal discarded wire type Z". And the discarded wire type immediately before that is the "discarded wire type Z'". In the example shown in FIG. 15, eight types of product workpieces A to H are manufactured in sequence, and an example is shown in which the discarded workpiece (discarded wire type Z') at the terminal 44 reaches the next processing step at the n-th cycle and reaches the post-cutting step at the m-th cycle.
[0062] [Calculation method of the distance L" from the first processing device 21 (processing step 1) to the winding terminal 44] Next, a method for calculating the distance L" (see FIG. 14) from the first processing device 21 (processing step 1) to the winding terminal 44 will be described. The winding terminal 44 is detected while the angular wire W is being conveyed. When the amount of movement from the moment of detection until the conveyance of the detected conveyance cycle ends is defined as ΔL", the distance L"k from the first processing device 21 to the terminal 44 when the k-th cycle in which the terminal 44 is detected ends is L"k = L"S - L1 - ΔL" which is represented by. L"S is the distance from the cutting device 15 to the terminal detection sensor and is a fixed value.
[0063] Here, since the distance by which the angular wire W is conveyed in each cycle becomes the wire type length cut out in the post-cutting step of the next conveyance cycle, the conveyance distance becomes the wire type length in the pre-cutting step of the previous conveyance cycle. When the wire type length before cutting is defined as L"I, the distance L" from the first processing device 21 to the winding terminal 44 in the next conveyance cycle k+1 is L" k+1 = L"k - L"I = L"S - L1 - ΔL" - L"I It is represented by. Here, assuming the final work length is L”E in order to surely pay out the winding end 44, it is necessary to make the waste work length of the waste work immediately before the final work variable. Since the shortest work length that can be made by the equipment is LZ, the total waste length L”Z of the end 44 needs to satisfy the following conditions. 2xLZ + L”E ≧ L”Z > LZ + L”E
[0064] That is, if it is confirmed every cycle whether the distance L” from the first processing device 21 to the winding end 44 satisfies the above conditions, the timing of changing from the in-sequence build to the waste wire type can be known. Assuming that a determination is made in the next processing step from the wire type information transfer timing (refer to the flowchart shown in FIG. 12), 2xLZ + L”E ≧ L” - L0 > LZ + L”E (L0: wire type length of the next processing step) ··· Condition (1) At this time, the wire length L’Z’ of the waste wire type “Z’” (waste work immediately before the final work) is L’Z’ = L” - L0 - L”E It is represented by.
[0065] Since it is only necessary to change the wire type information of the next processing step to the waste wire type “Z’” at the timing that satisfies the above condition (1), as shown in Table T4, assuming that the waste wire type reaches the next processing step at the nth cycle, it means that the following condition was satisfied at the end of the (n - 1)th cycle. 2xLZ + L”E ≧ L” n-1 -La > LZ + L”E (La: from wire type A of the next processing step) At this time, the wire length L’Z’ of the waste wire type “Z’” is L’Z’ = L” - La - L”E.
[0066] In the next cycle ((n + 1)th cycle), the end waste wire type “Z”” that becomes the final work is stored in the next processing step, and processing is performed with a wire length of L”E. Furthermore, after the next cycle, since there is no supplied square wire W, “N” (no wire type) is stored and the operation is stopped. In this way, the waste wire type [Z’], the end waste wire type “Z””, and “N” (no wire type) are stored, and when the information of the waste wire type reaches the post-cutting process, the waste work of the end 44 is automatically paid out by the loading device 16.
[0067] (Effect) According to the above-described fourth embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, it becomes possible to manufacture the product work up to near the winding end 44 fed out from the bobbin, improving the winding yield and eliminating the work involving equipment stoppage, thus improving productivity and operating rate.
[0068] E. Other Embodiments (E1) In each of the above embodiments, it is assumed that the product works A to H are manufactured as materials constituting a motor mounted on a certain vehicle. By setting the wire type information, it is possible to continuously manufacture the product works as materials constituting different motors mounted on different vehicles continuously following the manufacture of the product works A to H. That is, by setting the wire type information, continuous manufacturing can be carried out without stopping the equipment, enabling so-called mixed-flow production in which motors for a plurality of vehicle types are manufactured in a mixed manner.
[0069] A specific example will be described with reference to FIG. 16. FIG. 16 is a diagram showing the storage form of the wire type information read into each process in table T5 for each conveyance cycle. The form shown in FIG. 16 alternately manufactures the product works A to H that are materials for the product P1 and the product works A' to H' that are materials for the product P2, and shows an example of the wire type information when the product is switched. Note that the products P1 and P2 are products that can be made with the same winding. As shown in FIG. 16, at the nth cycle, the switch from the product P1 to the product P2 starts, and as the cycle progresses, the wire type of the product P2 fills the equipment. At the time of the m + 2th cycle, all the processes are switched to the wire type of the product P2 and the switching is completed. During this period, equipment stoppage is not required. Also, if it is switched from the product P2 to the product P1 or another product that can be made with the same winding, automatic switching is similarly possible and mixed-flow production is possible.
[0070] (E2) In each of the above embodiments, the conveying unit 14 is constituted by two conveying devices 26 and 27, but the number of conveying devices may be one. It may be configured to repeat an operation of gripping and conveying the angular wire W by one conveying device, releasing the angular wire W, and returning to the next chuck position again.
[0071] (E3) In each of the above embodiments, the processing unit 13 is constituted by a plurality of processing devices 21 to 25, but the number of processing devices may be one.
[0072] (E4) In the fourth embodiment above, the mark detection sensor 28 is also assumed to function as a terminal detection sensor for detecting the end 44 of the winding, but a terminal detection sensor may be provided separately from the mark detection sensor 28.
[0073] (E5) In each of the above embodiments, the angular wire W as the wire material is an insulated coated copper wire that becomes the linear material of the segment coil of the vehicle motor, but the wire material is not limited to this. Further, the processing devices 21 to 25 are peeling devices for peeling the insulating coating, but may be devices for performing other processing.
[0074] The present disclosure is not limited to the above embodiments, and can be realized in various configurations without departing from the gist thereof. For example, the technical features in each embodiment corresponding to the technical features in each form described in the summary of the invention can be appropriately replaced or combined in order to solve some or all of the above problems or to achieve some or all of the above effects. Further, if the technical feature is not described as essential in this specification, it can be appropriately deleted.
