Abstract
Description
Technical Field
[0001] This invention relates to a terminal supply crimping device. Background Technology
[0002] A known type of terminal strip reel is used to continuously or intermittently supply multiple terminals to a crimping device. The terminal strip reel winds a terminal strip consisting of multiple terminals connected in a strip. In the terminal strip reel, strip-shaped interlayer paper is wound between the terminal strips to prevent them from tangling. The terminal strip reel winds the terminal strip and interlayer paper in an overlapping manner.
[0003] Previously, a terminal supply crimping device was known, which feeds terminal tape from a terminal tape reel and crimps the terminals of the fed terminal tape to an electrical wire. For example, Patent Document 1 discloses a terminal supply crimping device comprising a terminal tape supply device and a terminal crimping machine. The terminal tape supply device includes a drive unit for feeding the terminal tape from the terminal tape reel; the terminal crimping machine includes feed claws for feeding the terminal tape into a die for terminal crimping. In the terminal tape supply device described in Patent Document 1, the drive unit for feeding the terminal tape from the terminal tape reel is an interlayer paper winding device that winds the interlayer paper. According to Patent Document 1, when the interlayer paper winding reel of the interlayer paper winding device is driven to rotate by an electric motor, the terminal tape reel rotates by winding the interlayer paper, feeding the terminal tape from the terminal tape reel.
[0004] According to the structure in Patent Document 1, since the terminal strip is fed from the terminal strip reel using an interlayer paper take-up device, the load on the terminal strip due to the drive of the feed claw of the terminal crimping machine can be considered reduced. Without the interlayer paper take-up device to assist in feeding the terminal strip, the terminal strip is fed from the terminal strip reel using the feed claw. Therefore, the load on the terminal strip from the feed claw is greater. Consequently, the possibility of terminal breakage due to the aforementioned load also increases.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2009-218068 Summary of the Invention (a) Technical problems to be solved
[0006] However, in the structure described in Patent Document 1, which uses an interlayer paper take-up device to rotate the terminal tape reel, sometimes it is only necessary to eliminate slack in the interlayer paper through winding. If the interlayer paper take-up device is driven in such cases, the terminal tape reel, which does not need to be rotated, may also rotate. Alternatively, when it is desired to rotate the interlayer paper take-up reel, such as when changing the terminal tape reel, it is difficult for the user to do so using arm strength due to the load (braking force) of the motor. Although it is possible to rotate the interlayer paper take-up reel using the driving force of the motor, it requires, for example, buttons, wiring, control programs, etc., for this purpose. In other words, although the terminal supply crimping device described in Patent Document 1 can reduce the load on the terminal due to the terminal tape feed device when supplying the terminal tape by using the drive of the interlayer paper take-up device, it also restricts the free operation of the interlayer paper take-up reel.
[0007] The present invention was made in response to the above-mentioned situation, and its object is to provide a terminal supply crimping device that can reduce the load applied to the terminals when supplying the terminal strip, and allows for more free operation of the interlayer paper take-up reel when desired. (II) Technical Solution
[0008] The terminal supply crimping apparatus of the present invention comprises: a support portion that rotatably supports a terminal tape reel that winds a terminal tape and interlayer paper in an overlapping manner; a crimping device that crimps the terminals of the terminal tape to an electrical wire; a terminal tape feeding device that feeds the terminal tape from the terminal tape reel to the crimping device; an interlayer paper take-up reel that takes up the interlayer paper extending from the terminal tape reel; and a drive device connected to the interlayer paper take-up reel and rotating the interlayer paper take-up reel. The drive device is configured to vary the torque supplied to the interlayer paper take-up reel.
[0009] According to the aforementioned terminal supply crimping device, the drive unit is configured to vary the torque supplied to the interlayer paper take-up reel, thus enabling the supply of a larger torque to the interlayer paper take-up reel, thereby assisting in the rotation of the terminal tape reel. This reduces the load applied to the terminals by the terminal tape feeder during terminal tape supply. On the other hand, when desired, only a smaller torque needs to be supplied to the interlayer paper take-up reel, allowing for more flexible operation of the interlayer paper take-up reel.
[0010] According to a second embodiment of the terminal supply crimping device of the present invention, the driving device is configured to provide at least two torques to the interlayer paper take-up reel, including a first torque and a second torque, wherein the first torque enables the terminal reel to rotate about the support, and the second torque is smaller than the first torque and cannot enable the terminal reel to rotate about the support.
[0011] According to the terminal supply crimping device, the terminal tape reel does not rotate when a second torque is provided to the interlayer paper take-up reel, thus preventing unnecessary rotation of the terminal tape reel when the drive device is driven to rotate the interlayer paper take-up reel.
[0012] According to a third embodiment of the terminal supply crimping device based on the second embodiment, the supply crimping device includes an interface for initiating a start operation of supplying the terminal strip, and also includes a control device connected to the drive device. The control device is configured to, when the start operation is performed, control the drive device to provide the second torque to the interlayer paper take-up reel.
[0013] According to the terminal supply crimping device, the interlayer paper take-up reel can be rotated to take up the loose interlayer paper before the terminal tape is started to be supplied, and the terminal tape reel will not be rotated unnecessarily.
[0014] According to a fourth embodiment of the terminal supply crimping device of the present invention, the driving device includes a rotating shaft for rotation. The rotating shaft includes: a first connecting portion capable of selectively engaging or disengaging with respect to the interlayer paper take-up reel; and a second connecting portion that is fixed to the interlayer paper take-up reel by friction when the rotational load of the interlayer paper take-up reel is less than a predetermined first load, and that slides relative to the interlayer paper take-up reel when the rotational load of the interlayer paper take-up reel is greater than or equal to the first load.
[0015] According to the supply crimping device of this terminal, if the first connecting part is connected to the interlayer paper take-up reel, the torque of the rotating shaft can be transmitted to the interlayer paper take-up reel, thus providing a relatively large torque to the interlayer paper take-up reel. Furthermore, if the first connecting part is separated from the interlayer paper take-up reel, when the rotational load of the interlayer paper take-up reel is greater than or equal to a first load, the rotating shaft slides relative to the interlayer paper take-up reel. Therefore, the drive device can only transmit a torque to the interlayer paper take-up reel that does not exceed the torque corresponding to the first load. Therefore, according to this structure, the torque provided by the drive device to the interlayer paper take-up reel can be easily varied.
[0016] According to a fifth embodiment of the terminal supply crimping device of the fourth embodiment, the first connecting portion has a movable shaft that can be positioned in a first position and a second position closer to the interlayer paper take-up reel than the first position. The interlayer paper take-up reel has an engaging hole that is inserted into the movable shaft when it is in the second position and disengaged from it when it is in the first position.
[0017] According to the supply crimping device of this terminal, the first connecting part can be connected / disconnected from the interlayer paper take-up reel using a simple structure that allows the movable shaft to be inserted / disconnected from the engagement hole. In other words, the torque supplied by the drive device to the interlayer paper take-up reel can be easily changed using a simple structure that allows the movable shaft to be inserted / disconnected from the engagement hole.
[0018] According to a sixth embodiment of the terminal supply crimping device based on the fourth or fifth embodiment, the driving device further comprises: a drive motor having a drive shaft for rotation; a first pulley connected to the drive shaft; a second pulley connected to the rotation shaft; and an annular belt wound between the first pulley and the second pulley. The belt is configured to slide relative to at least one of the first pulley and the second pulley when the rotational load of the interlayer paper take-up reel is a second load greater than the first load.
[0019] According to the terminal supply crimping device, even if the rotational load of the interlayer paper take-up reel increases abnormally for some reason, the belt will slide relative to at least one of the first pulley and the second pulley, thereby preventing excessive load from acting on the first connecting part, etc. As a result, damage to the first connecting part, etc., can be suppressed.
[0020] According to a seventh embodiment of the terminal supply crimping device of the present invention, the supply crimping device further comprises: a detection device that detects the force applied to the terminal strip by the terminal strip feeding device when the terminal strip is being conveyed; and a warning device connected to the detection device that issues a warning when the force detected by the detection device is higher than a predetermined force for a predetermined time.
[0021] In the event of an abnormality where the drive unit fails to provide the intended torque to the interlayer paper take-up reel, the interlayer paper take-up device will not assist the terminal belt reel in rotating as intended. Therefore, the force detected by the detection device exceeding the specified force may persist for an extended period. Thus, by detecting situations where the force detected by the detection device exceeds the specified force for an extended period, it is possible to identify any abnormalities exceeding the specified limits. Based on the terminal supply crimping device, such abnormalities can be detected, and the user will be alerted to the occurrence of the abnormality.
[0022] According to an eighth embodiment of the terminal supply crimping device of the present invention, the driving device is configured to be able to change the braking force on the interlayer paper take-up reel when stopped.
[0023] According to the supply crimping device of the terminal, since the drive device is configured to change the braking force provided to the interlayer paper take-up reel, the interlayer paper take-up reel can be operated more freely when desired by applying a smaller braking force to it.
[0024] According to a ninth embodiment of the terminal supply crimping device of the eighth embodiment, the drive device is configured to provide a braking force to the interlayer paper take-up reel that can overcome the braking force and manually rotate the interlayer paper take-up reel.
[0025] According to the supply crimping device of the terminal, the drive device can make the braking force provided to the interlayer paper take-up reel a braking force that enables the interlayer paper take-up reel to be manually rotated. Therefore, when desired, by adding this small braking force to the interlayer paper take-up reel, the interlayer paper take-up reel can be operated manually. (III) Beneficial Effects
[0026] The terminal feeding crimping device according to the invention can reduce the load applied to the terminals when feeding the terminal strip, and can operate the interlayer paper take-up reel more freely when desired. Attached Figure Description

Detailed Implementation
[0028] Embodiments of the present invention will now be described with reference to the accompanying drawings. Furthermore, the embodiments described herein are not intended to limit the invention. Additionally, components / parts that perform the same function are labeled with the same reference numerals, and repeated descriptions are omitted or simplified where appropriate.
[0029] [First Implementation Method] Figure 1 This is a schematic front view of a terminal supply crimping device 10 (hereinafter referred to as supply crimping device 10) according to one embodiment. In the following description, unless otherwise specified, the rotation axis direction of the terminal tape reel 5 is set to the front-back direction, and the direction of the horizontally fed terminal tape 6 is set to the right. The reference numerals F, Rr, L, R, U, and D in the drawings represent front, back, left, right, up, and down, respectively. However, the above directions are determined for the convenience of explanation and do not limit the arrangement of the supply crimping device 10, nor do they limit the present invention in any way.
[0030] like Figure 1 As shown, the supply crimping device 10 of this embodiment includes: a support portion 20 supporting the terminal belt reel 5, a crimper 30, a press 40, an interlayer paper winding device 50, a tension detection device 80, and a control device 90 (see reference). Figure 5 ).
[0031] like Figure 1 As shown, the terminal reel 5 supplies overlapping winding of the strip-shaped terminal strip 6 and the strip-shaped interlayer paper 7, and is configured such that, from a view along the winding axis (in the direction of the winding axis) Figure 1 (When viewed from the front-to-back direction) It is roughly circular. Terminal strip 6 is formed by connecting multiple terminals to form a strip.
[0032] The support portion 20 rotatably supports the terminal tape reel 5. The support portion 20 includes a support column 21, a horizontal arm 22, and a rotating portion 23. The support column 21 extends vertically. The horizontal arm 22 engages with the support column 21 and extends horizontally. The rotating portion 23 is located at the open end of the horizontal arm 22 (the end opposite to the end that engages with the support column 21) and is supported on the horizontal arm 22 in a manner that allows rotation in the horizontal direction. The core 8 of the terminal tape reel 5 is inserted into the rotating portion 23. Thus, the terminal tape reel 5 is supported on the support portion 20 in a manner that allows rotation in the horizontal direction. However, the support portion 20 is not limited to simply supporting the terminal tape reel 5 rotatably.
[0033] The crimper 30 is a device that feeds the terminals of the terminal strip 6 from the terminal strip reel 5 and crimps them onto the wire. The crimper 30 includes a crimping device 31 and a terminal strip feeding device 32. The crimping device 31 is used to crimp the terminals of the terminal strip 6 onto the wire. Various known crimping devices can be used as the crimping device 31. Here, the crimping device 31 has teeth for crimping terminals and a movable part (not shown) that moves vertically. The press 40 presses the movable part of the crimping device 31 downwards. This crimps the terminals onto the wire. The terminal strip feeding device 32 is configured to feed the terminal strip 6 from the terminal strip reel 5 to the crimping device 31. The terminal strip feeding device 32 is positioned closer to the support portion 20 than the crimping device 31, specifically to the left in this case. Figure 1 As shown, the terminal tape feeding device 32 includes a feeding claw 32a that feeds the terminal tape 6 from the terminal tape reel 5 to the crimping device 31. The feeding claw 32a swings left and right in conjunction with the terminal crimping action of the crimping device 31, which is driven by the press 40. The terminal tape feeding device 32 feeds the terminal tape 6 to the right by engaging the left-right swinging feeding claw 32a with the terminal tape 6. Thus, the terminal tape 6 from the terminal tape reel 5 is fed to the crimping device 31.
[0034] The interlayer paper winding device 50 is a device for winding the interlayer paper 7 that is fed from the terminal tape reel 5 together with the terminal tape 6. For example... Figure 1 As shown, the interlayer paper take-up device 50 includes: an interlayer paper take-up reel 60 that takes up interlayer paper 7 extending from the terminal tape reel 5; and a drive device 70 that rotates the interlayer paper take-up reel 60. The drive device 70 is configured to be connected to the interlayer paper take-up reel 60 and to provide torque to the interlayer paper take-up reel 60.
[0035] Figure 2 This is a right-side view of the interlayer paper winding device 50. Figure 3 This is a front view of the interlayer paper winding device 50. (See image below.) Figure 2 and Figure 3As shown, the interlayer paper take-up reel 60 includes: a take-up circular plate 61, a plurality of take-up shafts 62, and a force-receiving part 63. Here, the take-up circular plate 61 is configured to be approximately circular when viewed from the front or back. The central axis of the take-up circular plate 61 extends in the front-rear direction. The central axis of the take-up circular plate 61 is parallel to the central axis of the terminal tape reel 5. A central hole 61a extending in the front-rear direction is formed around the central axis of the take-up circular plate 61.
[0036] Multiple take-up spools 62 are fixed to a take-up circular plate 61. The take-up spools 62 extend forward from the front surface of the take-up circular plate 61. The number of take-up spools 62 is four. The four take-up spools 62 are arranged at 90-degree intervals around a circumference centered on the central axis of the take-up circular plate 61.
[0037] The force-receiving part 63 is located at the center of the circumference of the winding circular plate 61. The force-receiving part 63 is formed in a generally cylindrical shape. Figure 2 As shown, the force-receiving part 63 has a central hole 63a that extends in the front-rear direction. The force-receiving part 63 is fixed to the winding disc 61 in such a way that the central axis of the central hole 63a is aligned with the central axis of the winding disc 61. Here, the force-receiving part 63 is fixed to the front surface of the winding disc 61 and extends forward from the winding disc 61.
[0038] like Figure 2 As shown, a generally cylindrical retaining ring 64 is inserted into the central hole 63a of the force-receiving part 63. The retaining ring 64 has a central hole 64a that extends in the front-rear direction. The central axis of the central hole 64a coincides with the central axis of the winding disc 61 and the central axis of the force-receiving part 63. The retaining ring 64 is fixed here so that it cannot rotate relative to the central hole 63a of the force-receiving part 63. The retaining ring 64 can be fixed relative to the central hole 63a, for example, by driving it into the central hole 63a, or by other means such as fixing screws. In this embodiment, the retaining ring 64 is made of resin.
[0039] like Figure 2 As shown, the force-receiving part 63 has a convex-edged force-receiving plate 63b. The force-receiving plate 63b protrudes outward in the circumferential direction of the force-receiving part 63 compared to the other parts of the force-receiving part 63. A plurality of engaging holes 63c are formed on the force-receiving plate 63b. Here, the plurality of engaging holes 63c penetrate the force-receiving plate 63b in the front-rear direction. However, the engaging holes 63c may not be through holes, but may be non-through recesses. In addition, the number of engaging holes 63c may be only one. Here, the plurality of engaging holes 63c are arranged at equal angles on a circumference centered on the central axis of the force-receiving part 63.
[0040] like Figure 2As shown, the drive unit 70 includes: a drive motor 71, a first pulley 72, a belt 73, a rotating shaft 74, and a second pulley 75. The drive motor 71 is a DC motor without torque-changing capabilities. However, the type of drive motor 71 is not limited. The drive motor 71 has a rotating drive shaft 71a. The drive shaft 71a extends in the front-to-back direction and rotates in the left-to-right direction. The first pulley 72 is connected to the drive shaft 71a and rotates together with it.
[0041] Belt 73 is an annular belt wound between the first pulley 72 and the second pulley 75. In this embodiment, belt 73 is a circular belt with a generally circular cross-sectional shape. However, the type of belt 73 is not limited. For example, belt 73 can also be a flat belt with a generally rectangular cross-sectional shape.
[0042] The rotating shaft 74 is generally cylindrical, with its axis extending in the front-to-back direction. A second pulley 75 is connected to the rotating shaft 74. The rotating shaft 74 receives the force of the drive motor 71 via the first pulley 72, the belt 73, and the second pulley 75, and rotates about its axis. Figure 2 As shown, the rotating shaft 74 includes: a main shaft 74a, a bracket 74b, and a plunger 74c. A second pulley 75 is connected near the rear end of the main shaft 74a. A portion of the main shaft 74a that is forward of the second pulley 75 is inserted into the center hole 61a of the winding disc 61 and the center hole 64a of the retaining ring 64. The main shaft 74a contacts the center hole 64a of the retaining ring 64. The center hole 61a of the winding disc 61 is formed to be larger than the main shaft 74a when viewed from the front-rear direction, and does not contact the main shaft 74a.
[0043] like Figure 2 As shown, the front end of the main shaft 74a is forward of the force-bearing part 63. A bracket 74b is provided at the front end of the main shaft 74a. The bracket 74b is formed into a flat plate. The bracket 74b extends substantially perpendicular to the axis of the main shaft 74a and rotates together with the main shaft 74a. A portion of the bracket 74b protrudes outward in the circumferential direction of the main shaft 74a. The bracket 74b is arranged substantially parallel to the force-bearing plate 63b of the force-bearing part 63.
[0044] A plunger 74c is mounted on the bracket 74b. The plunger 74c is a rod-shaped component and extends substantially perpendicular to the bracket 74b, in other words, substantially parallel to the axis of the main shaft 74a. Figure 2As shown, the plunger 74c includes: a cylindrical housing 74c1, a movable shaft 74c2 partially housed within the housing 74c1, and a spring (not shown) housed within the housing 74c1. The housing 74c1 is mounted on a bracket 74b. The movable shaft 74c2 is configured to move forward and backward along the inner periphery of the housing 74c1. The movable shaft 74c2 is subjected to force by the spring in the direction of the force plate 63b (rearward in this case). By holding the gripping part 74c3 formed at the front end of the movable shaft 74c2, the user can overcome the spring force and move the movable shaft 74c2 towards the opposite side (front in this case) of the force plate 63b.
[0045] The movable shaft 74c2 is configured to rotate left and right relative to the housing 74c1. When the movable shaft 74c2 is positioned at a predetermined rotational position under forward tension, it engages with the housing 74c1. This engagement overcomes the spring force, fixing the forward / backward position of the movable shaft 74c2. Thus, the movable shaft 74c2 is configured to be positioned at a first position P1 (refer to…) where it engages with the housing 74c1. Figure 2 ), and the second position P2, which is closer to the interlayer paper take-up reel 60 than the first position P1 (refer to Figure 4 ).
[0046] The plunger 74c is configured to overlap with the circumference of the circle having multiple engagement holes 63c when viewed from the front-to-back direction. Figure 4 This is a right-side view of the interlayer paper winding device 50 with the movable shaft 74c2 of the plunger 74c inserted into the engagement hole 63c. (See image below.) Figure 4 As shown, the movable shaft 74c2 is inserted into the engagement hole 63c when positioned in the second position P2. Furthermore, as... Figure 2 As shown, the movable shaft 74c2 disengages from the engagement hole 63c when positioned in the first position P1. When engaging the plunger 74c with the engagement hole 63c, the user, for example, releases the movable shaft 74c2 from the housing 74c1, and then rotates the interlayer paper take-up reel 60. This inserts the movable shaft 74c2 into the engagement hole 63c, which is immediately adjacent to the direction of rotation. When releasing the plunger 74c from the engagement hole 63c, the user positions the movable shaft 74c2 in the first position P1 and engages it with the housing 74c1.
[0047] By inserting the movable shaft 74c2 of the plunger 74c into the engagement hole 63c, the rotating shaft 74 is engaged with the interlayer paper take-up reel 60. This allows approximately all of the rotational force of the rotating shaft 74 to be transmitted to the interlayer paper take-up reel 60. The plunger 74c constitutes a first connecting portion C1 of the rotating shaft 74, which can be selectively engaged or disengaged relative to the interlayer paper take-up reel 60.
[0048] A portion of the rotational force of the rotating shaft 74 is also transmitted to the interlayer paper take-up reel 60 through the friction between the main shaft 74a and the retaining ring 64. The contact portion between the main shaft 74a and the retaining ring 64 constitutes a second connecting portion C2 of the rotating shaft 74, which transmits the torque of the rotating shaft 74 to the interlayer paper take-up reel 60. When the rotational load of the interlayer paper take-up reel 60 is less than a predetermined load (hereinafter referred to as the first load), the second connecting portion C2 is fixed to the interlayer paper take-up reel 60 (more specifically, the retaining ring 64) by friction. In other words, no slippage occurs between the second connecting portion C2 and the interlayer paper take-up reel 60. As a result, the interlayer paper take-up reel 60 rotates together with the rotating shaft 74. When the rotational load of the interlayer paper take-up reel 60 is greater than or equal to the first load, the second connecting portion C2 slides relative to the retaining ring 64. Therefore, when the rotational load of the interlayer paper take-up reel 60 is above the first load and the first connecting part C1 is not engaged with the interlayer paper take-up reel 60, the interlayer paper take-up reel 60 does not rotate together with the rotating shaft 74.
[0049] like Figure 1 As shown, a tension detection device 80 is provided between the terminal tape reel 5 and the terminal tape feeding device 32 in the path of the terminal tape 6. The tension detection device 80 is configured to detect the force applied to the terminal tape 6 by the terminal tape feeding device 32 when the terminal tape 6 is being fed. Here, the tension detection device 80 detects whether the tension of the terminal tape 6 fed from the terminal tape reel 5 exceeds a specified tension. When the amount by which the interlayer paper take-up device 50 rotates the terminal tape reel 5 (the feed length of the terminal tape 6) is greater than the amount by which the terminal tape feeding device 32 feeds the terminal tape 6, the terminal tape 6 will slack. Conversely, the terminal tape 6 will tighten. As a result, the tension of the terminal tape 6 changes.
[0050] like Figure 1 As shown, the tension detection device 80 includes a guide member 81 that guides the terminal strip 6. The guide member 81 is configured to move in the left and right directions. The guide member 81 is subjected to a force to the left by a spring (not shown). When the terminal strip 6 is tensioned, the guide member 81 moves to the right against the force of the spring due to the pull of the terminal strip 6. The tension detection device 80 includes an optical sensor 82 that detects the guide member 81. When the terminal strip 6 is tensioned by a tension exceeding a predetermined tension, causing the guide member 81 to move to the right relative to a distance corresponding to the predetermined tension, the optical sensor 82 detects the guide member 81. Thus, the condition where the tension of the terminal strip 6 exceeds the predetermined tension is detected. The tension detection device 80 is configured to send a signal when the optical sensor 82 detects the guide member 81.
[0051] The crimping device 10 includes a control device 90, which controls the operation of the press 40 and the interlayer paper winding device 50, and receives signals from the tension detection device 80. Figure 5 This is a block diagram of the crimping device 10. (Example) Figure 5 As shown, the control device 90 is connected to the press 40, the drive motor 71 of the interlayer paper winding device 50, and the tension detection device 80. The crimping device 31 and the terminal belt feed device 32 operate in conjunction with the press 40. The structure of the control device 90 is not particularly limited. The control device 90 may, for example, include a central processing unit (CPU), ROM, RAM, etc., storing programs to be executed by the CPU. Each part of the control device 90 may be composed of software or hardware. Furthermore, each part may be a processor or a circuit.
[0052] like Figure 5 As shown, the control device 90 includes: an operation control unit 91, a warning unit 92, an operation screen 93, and a warning device 94. The operation control unit 91 controls the operation of the press 40 and the interlayer paper take-up device 50 to supply / crimp the terminals. The operation of the supply crimping device 10 will be described in detail later. The warning unit 92 is connected to the tension detection device 80 and is configured to issue a warning signal when the force detected by the tension detection device 80 exceeds a predetermined force for a predetermined time. Specifically, the warning unit 92 issues a warning signal when it continuously receives signals from the tension detection device 80 for a predetermined time. The warning unit 92 may also issue warning signals in other situations, but these situations will not be described. The warning device 94 receives the warning signal issued by the warning unit 92 and issues a warning to the user. The warning device 94 includes, for example, a buzzer or a warning indicator light. However, the structure of the warning device 94 is not particularly limited. The warning may also include stopping the operation of the supply crimping device 10.
[0053] The operation screen 93 is, for example, an interface for starting the supply of the terminal strip 6, temporarily stopping the supply, and individually driving the interlayer paper take-up device 50. However, the interface for performing various operations of the supply crimping device 10 is not limited to the operation screen displayed on the monitor. Part or all of the interface for performing various operations of the supply crimping device 10 may be composed of mechanical buttons or switches. In addition, the control device 90 may also have other processing units that perform other functions, but descriptions and illustrations are omitted.
[0054] [Terminal tape supply and crimping operation] The following describes the operation of the supply and crimping device 10 related to the supply of terminal tape 6 from the terminal tape reel 5 and the crimping of the terminal tape 6. When supplying the terminal tape 6 from the terminal tape reel 5, the user first places the terminal tape reel 5 on the support portion 20. Then, the user feeds the terminal tape 6 and interlayer paper 7 from the terminal tape reel 5. The fed terminal tape 6 is placed on the crimper 30 via the tension detection device 80. The fed interlayer paper 7 is placed on the interlayer paper take-up reel 60. More specifically, the interlayer paper 7 is placed on one of the multiple take-up shafts 62 in a manner that allows it to be wound onto multiple take-up shafts 62.
[0055] like Figure 2 As shown, when the interlayer paper 7 (refer to) is placed... Figure 1 When the plunger 74c is positioned on the interlayer paper take-up reel 60, it is preferable that it is not engaged with the interlayer paper take-up reel 60. In this state, the user can freely rotate the interlayer paper take-up reel 60. In this state, since the drive unit 70 and the interlayer paper take-up reel 60 are connected only by friction between the second connecting part C2 and the retaining ring 64, the user can easily rotate the interlayer paper take-up reel 60. In other words, in this state, the second connecting part C2 of the drive unit 70 only provides a braking force to the interlayer paper take-up reel 60 sufficient to overcome braking force and manually rotate the interlayer paper take-up reel 60. Therefore, the user can freely manually rotate the interlayer paper take-up reel 60. The braking force required to manually rotate the interlayer paper take-up reel 60 is, for example, a braking force of 0.1 N or less.
[0056] Because the interlayer paper take-up reel 60 can be freely rotated manually, the user can easily set the interlayer paper 7 onto the interlayer paper take-up reel 60. In addition, after setting, the interlayer paper take-up reel 60 can be manually rotated to take up the loose interlayer paper 7.
[0057] Next, the user engages the plunger 74c with the interlayer paper take-up reel 60. This creates a state where approximately all the torque of the rotating shaft 74 is transmitted to the interlayer paper take-up reel 60. In this state, the interlayer paper take-up reel 60 can also be braked by the drive unit 70 without being manually rotated. However, even in this state, the interlayer paper take-up reel 60 can be manually rotated. Thus, the drive unit 70 is configured to change the braking force on the interlayer paper take-up reel 60 at the time of stopping by whether or not the plunger 74c is engaged with the interlayer paper take-up reel 60.
[0058] Next, the user operates the operation screen 93 to start the supply / crimping operation of the terminal tape 6. During the supply / crimping operation of the terminal tape 6, the terminal tape 6 is fed to the crimping device 31 via the terminal tape feeder 32. The terminals of the terminal tape 6 fed to the crimping device 31 are crimped to the wire. As the terminal tape 6 is fed, it becomes taut. When the tension of the terminal tape 6 reaches a certain level, the tension detection device 80 detects this. The control device 90 receives a signal from the tension detection device 80 indicating that the tension of the terminal tape 6 has reached a certain level. If the operation control unit 91 of the control device 90 receives a signal from the tension detection device 80, it drives the drive motor 71. As a result, the interlayer paper take-up reel 60 rotates together with the rotating shaft 74. The interlayer paper 7 is taken up by the interlayer paper take-up reel 60 and drawn out from the terminal tape reel 5. As a result, the terminal tape reel 5 rotates, assisting in the feeding of the terminal tape 6 from the terminal tape reel 5.
[0059] As described above, when it is not conducive to the interlayer paper take-up device 50 to assist the rotation of the terminal tape reel 5, the force used to feed the terminal tape 6 is entirely applied to the terminal tape 6 that is engaged with the feed claw 32a of the terminal tape feed device 32. The greater the force applied to the terminal tape 6, the greater the possibility of damage to the terminal tape 6. Therefore, it is preferable to use the interlayer paper take-up device 50 to assist the rotation of the terminal tape reel 5 in this way. According to the supply crimping device 10 of this embodiment, the force applied to the terminal tape 6 can be reduced by using the interlayer paper take-up device 50 to assist the rotation of the terminal tape reel 5.
[0060] Here, if the length of the terminal tape 6 fed by the terminal tape feeder 32 is greater than the winding length of the interlayer paper 7 wound by the interlayer paper winding device 50, a portion of the interlayer paper 7 will not be wound by the interlayer paper winding reel 60 and will become slack. Such slack in the interlayer paper 7 is preferably removed by winding the interlayer paper 7 by the interlayer paper winding reel 60. In this case, the user can temporarily stop the feeding / crimping operation of the terminal tape 6. Afterwards, the user can release the engagement between the plunger 74c and the interlayer paper winding reel 60. Moreover, the user can operate the operation screen 93 to perform the winding operation of the interlayer paper 7, that is, to perform a separate drive operation of the interlayer paper winding device 50.
[0061] In this embodiment, if the winding operation of the interlayer paper 7 is performed with the plunger 74c disengaged from the interlayer paper take-up reel 60, the drive motor 71 is driven, and the rotating shaft 74 rotates. During the period when the interlayer paper 7 is slack, the interlayer paper take-up reel 60 and the rotating shaft 74 rotate together. As a result, the interlayer paper 7 is wound by the interlayer paper take-up reel 60. When the slack of the interlayer paper 7 is eliminated by being wound by the interlayer paper take-up reel 60, the rotational load of the terminal tape reel 5 acts on the interlayer paper 7, and the second connecting part C2 begins to slide between the retaining ring 64. Thus, the interlayer paper 7 can be wound in a way that avoids unnecessary rotation of the terminal tape reel 5.
[0062] Thus, the drive device 70 is configured to change the torque supplied to the interlayer paper take-up reel 60 by whether or not the plunger 74c is engaged with the interlayer paper take-up reel 60. Specifically, the drive device 70 is configured to provide a first torque and a second torque to the interlayer paper take-up reel 60. The first torque is sufficient to rotate the terminal tape reel 5 around the support portion 20, while the second torque is smaller than the first torque and cannot rotate the terminal tape reel 5 around the support portion 20. The first torque is the torque at which the first connecting portion C1 is engaged with the interlayer paper take-up reel 60, and is approximately equal to the torque that can be output by the rotating shaft 74. The second torque is the torque at which the engagement of the first connecting portion C1 with the interlayer paper take-up reel 60 is released, and is approximately equal to the torque that can be transmitted by friction between the second connecting portion C2 and the interlayer paper take-up reel 60.
[0063] Furthermore, the winding of the loose interlayer paper 7 as described above can also be performed by manually rotating the interlayer paper winding reel 60. Alternatively, the winding of the interlayer paper 7 can be performed by driving the drive motor 71 while the first connecting part C1 is disengaged from the interlayer paper winding reel 60, before the feeding / crimping operation of the start terminal tape 6.
[0064] When all terminals of the terminal tape 6 have been crimped, it is preferable to rewind the interlayer paper 7 back into the core 8 of the terminal tape reel 5 to remove the waste interlayer paper 7. In this operation, the user first releases the first connecting part C1 from the interlayer paper take-up reel 60. Then, the user rotates the terminal tape reel 5 counterclockwise when viewed from the front. At this time, the interlayer paper take-up reel 60 is in a state where it can be freely rotated manually, so the interlayer paper 7 can be wound into the core 8 of the terminal tape reel 5.
[0065] [Exception Handling 1] The following describes the troubleshooting process when an abnormality occurs in the supply crimping device 10 of this embodiment. As a first abnormality, the following situation is described: the plunger 74c fails to engage with the interlayer paper take-up reel 60 before the start of the terminal tape 6 supply / crimping operation. This situation may occur, for example, if the user forgets to engage the plunger 74c with the interlayer paper take-up reel 60. In this case, the interlayer paper take-up device 50 essentially does not contribute to the rotation of the terminal tape reel 5. Therefore, compared to the normal situation, a larger load is applied to the terminal tape 6 by the terminal tape feed device 32.
[0066] As described above, the supply crimping device 10 of this embodiment is configured to issue a warning when the time for continuously receiving signals from the tension detection device 80 exceeds a predetermined time. When the supply / crimping of the terminal strip 6 begins with the plunger 74c not engaged with the interlayer paper take-up reel 60, the terminal strip 6 is always in a taut state. Therefore, it is in a state where signals from the tension detection device 80 are constantly being sent. Under normal operation, the terminal strip 6 is repeatedly subjected to a taut state and a slightly slack state by the pulling of the terminal strip feed device 32 and the pressing of the interlayer paper take-up device 50. Therefore, an abnormality can be detected based on the time for continuously receiving signals from the tension detection device 80 exceeding a predetermined time.
[0067] When the crimping device 10 detects the above-mentioned abnormality, it will, for example, sound a buzzer or illuminate an indicator light, and stop the supply / crimping operation of the terminal strip 6. However, the type of warning action is not particularly limited.
[0068] [Exception Handling 2] As a second anomaly, an abnormal force is required during the rotation of the interlayer paper take-up reel 60. This situation may occur, for example, when the interlayer paper take-up reel 60, the support portion 20, or the terminal tape reel 5 is entangled with foreign objects. Without any troubleshooting, when such an anomaly occurs, the torque of the rotating shaft 74 will be continuously applied to the non-rotating interlayer paper take-up reel 60, potentially causing damage to the first connecting portion C1 and the engaging hole 63c. It also causes overload of the drive motor 71.
[0069] To address the aforementioned anomaly, the supply crimping device 10 of this embodiment is configured such that when the rotational load of the interlayer paper take-up reel 60 is a predetermined load (hereinafter referred to as the second load) or higher, the belt 73 slides relative to the first pulley 72 and the second pulley 75. The second load is set to be greater than the first load at which the second connecting portion C2 begins to slide relative to the retaining ring 64, and even with continuous application, it will not damage the first connecting portion C1 and the engagement hole 63c. Specifically, by making the belt 73 a round belt, the frictional force generated between the first pulley 72 and the second pulley 75 can be reduced. This makes it easier for the belt 73 to slide relative to the first pulley 72 and the second pulley 75. When the rotational load of the interlayer paper take-up reel 60 is greater than the second load, the belt 73 slides relative to the first pulley 72 and the second pulley 75, thus preventing excessive force from being applied to the first connecting portion C1 and the engagement hole 63c. Furthermore, the drive shaft 71a of the drive motor 71 rotates. This reduces the possibility of damage to the first connecting part C1 and the possibility of overload of the drive motor 71.
[0070] Furthermore, when the rotational load of the interlayer paper take-up reel 60 is a second load or higher, the belt 73 does not necessarily have to slide relative to both the first pulley 72 and the second pulley 75; it can slide relative to either one. The belt 73 only needs to be configured to slide relative to at least one of the first pulley 72 and the second pulley 75 when the rotational load of the interlayer paper take-up reel 60 is a second load or higher.
[0071] [Modifications of the First Embodiment] The supply crimping device 10 of the first embodiment can also be implemented through some modifications. Furthermore, in the following description of the modifications, the same reference numerals as in the first embodiment are used for components that perform the same functions as in the first embodiment. The same applies to other embodiments and modifications after the second embodiment.
[0072] For example, in a preferred modification, the movable shaft, which can be inserted into and disengaged from the engagement hole 63c, can be moved using an actuator. For example, the actuator can be a cylinder, and the movable shaft can be the extension / retraction shaft of the cylinder. Furthermore, the supply crimping device 10 can, for example, include a solenoid valve that controls the supply of compressed air to the cylinder. The solenoid valve can be connected to the control device 90 for automatic control. However, the actuator and its control method are not particularly limited.
[0073] The structure allows for automatic control of the insertion and disengagement of the movable shaft relative to the engagement hole 63c, eliminating the need for manual insertion of the movable shaft into the engagement hole 63c and thus preventing the possibility of forgetting to perform the operation or making a mistake. With this structure, the control device 90 can be configured to control the drive device 70 to rotate the rotating shaft 74 (in other words, to provide a second torque to the interlayer paper take-up reel 60) when the terminal tape 6 supply operation begins, even if there is slack in the interlayer paper 7 before the terminal tape 6 supply operation begins. Therefore, the terminal tape 6 can be supplied after the slack in the interlayer paper 7 is automatically removed. Furthermore, since the torque of the interlayer paper take-up reel 60 is a second torque, unnecessary rotation of the terminal tape reel 5 is prevented by addressing the slack in the winding of the interlayer paper 7.
[0074] Furthermore, since it is equipped with a sensor to detect the loosening of the interlayer paper 7, the supply crimping device 10 can automatically remove the loosening of the interlayer paper 7 before or during the supply of the terminal strip 6.
[0075] Furthermore, in other variations, the supply crimping device 10 may also include a sensor for detecting the insertion and disengagement of the movable shaft relative to the engagement hole 63c. The insertion and disengagement of the movable shaft relative to the engagement hole 63c can be performed by the user. With such a sensor, the possibility of the user forgetting or mistakenly performing the operation of inserting the movable shaft into the engagement hole 63c or disengaging the movable shaft from the engagement hole 63c can be reduced. The control device 90 may be configured to prohibit subsequent operations when the operation of inserting the movable shaft into the engagement hole 63c or disengaging the movable shaft from the engagement hole 63c is not performed properly.
[0076] Furthermore, the connection method between the first connecting part and the interlayer paper take-up reel is not limited to the method of inserting and disengaging the movable shaft relative to the engaging hole. The first connecting part is only required to be configured to selectively engage or disengage relative to the interlayer paper take-up reel; there are no other limitations. For example, the corresponding portions of the first connecting part and the interlayer paper take-up reel may have gear-shaped engaging portions or cam-shaped engaging portions. Additionally, the movable direction of the first connecting part (e.g., the movable direction of the movable shaft) is not limited to the axial direction of the rotating shaft, but may also be, for example, the circumferential direction of the rotating shaft. The same applies to the contact surface between the second connecting part and the interlayer paper take-up device; its orientation is not limited. For example, the contact surface between the second connecting part and the interlayer paper take-up device may face a direction parallel to the axis of the rotating shaft and the central axis of the interlayer paper take-up reel.
[0077] [Second Implementation] In the second embodiment, a different method than that used in the first embodiment and its variations is employed to change the torque and braking force supplied to the interlayer paper take-up reel 60. Figure 6 This is a rear view of the interlayer paper winding apparatus 50 according to the second embodiment. Although in Figure 6 While figures are omitted, in this embodiment, the drive unit 70 includes a connecting portion that connects the rotating shaft 74 to the interlayer paper take-up reel 60. This connecting portion securely connects the rotating shaft 74 to the interlayer paper take-up reel 60, which rotates together with the rotating shaft 74. The structure of this connecting portion is not limited. Figure 6 As shown, the drive device 70 of this embodiment includes a tension roller 76 in addition to the drive motor 71, the first pulley 72, the belt 73, the rotating shaft 74, and the second pulley 75. Furthermore, the drive motor 71 may also be a DC motor without torque conversion function.
[0078] like Figure 6 As shown, the structure of the drive motor 71, first pulley 72, belt 73, rotating shaft 74, and second pulley 75 in this embodiment is the same as in the first embodiment. The tension roller 76 is positioned further inward than the inner circumferential surface of the annular belt 73. The drive device 70 includes a roller moving part 77, which can position the tension roller 76 at a first adjustment position Pa1 (shown as a solid line) and a second adjustment position Pa2 (shown as a double-dotted line). The first adjustment position Pa1 is the position where the tension roller 76 abuts against the inner circumferential surface of the belt 73, and the second adjustment position Pa2 is further inward than the first adjustment position Pa1. However, the tension roller 76 can also be positioned further outward than the outer circumferential surface of the annular belt 73. In this case, the roller moving part 77 can be configured to position the tension roller 76 at a further first adjustment position where the tension roller 76 abuts against the outer circumferential surface of the belt 73, and at a further second adjustment position further outward than the aforementioned further first adjustment position.
[0079] The first adjustment position Pa1 is the position where the tension roller 76 presses the annular belt 73 from the inside out. The second adjustment position Pa2 is the position where the tension roller 76 is further inward than in the first adjustment position Pa1. When in the second adjustment position Pa2, the tension roller 76 may or may not be in contact with the inner circumferential surface of the belt 73. In both cases, the tension of the belt 73 when the tension roller 76 is positioned in the second adjustment position Pa2 is less than the tension of the belt 73 when the tension roller 76 is positioned in the first adjustment position Pa1. The tension roller 76 and the roller moving part 77 are examples of tension adjusting parts capable of adjusting the tension of the belt 73.
[0080] The roller moving part 77 supports the tension roller 76 and moves circumferentially along the belt 73. For example... Figure 6As shown, the roller moving part 77 can be configured, for example, to have an elongated hole 77a and a bolt / nut 77b, and can fix the tension roller 76 in a first adjustment position Pa1 or a second adjustment position Pa2. The roller moving part 77 may also have an actuator for moving the tension roller 76. When the roller moving part 77 has an actuator, the actuator can be controlled by the control device 90. The structure of the roller moving part 77 is not particularly limited.
[0081] In this embodiment, the torque and braking force supplied to the interlayer paper take-up reel 60 are varied by changing the tension of the belt 73. The frictional force between the belt 73 and the first pulley 72 and the second pulley 75 increases with increasing belt tension and decreases with decreasing belt tension. When the rotational load of the interlayer paper take-up reel 60 exceeds the static frictional force between the belt 73 and the first pulley 72 and the second pulley 75, the belt 73 begins to slide relative to the first pulley 72 and the second pulley 75. This static frictional force between the belt 73 and the first pulley 72 and the second pulley 75 can be varied according to the position of the tension roller 76. Therefore, the torque and braking force supplied to the interlayer paper take-up reel 60 by the drive device 70 can be varied using the tension roller 76 and the roller moving part 77.
[0082] Preferably, the torque provided to the interlayer paper take-up reel 60 when the tension roller 76 is positioned in the first adjustment position Pa1 can be a torque capable of rotating the terminal tape reel 5 around the support portion 20. Furthermore, the torque provided to the interlayer paper take-up reel 60 when the tension roller 76 is positioned in the second adjustment position Pa2 can be a torque that does not cause the terminal tape reel 5 to rotate around the support portion 20. Moreover, the braking force provided to the interlayer paper take-up reel 60 when the tension roller 76 is positioned in the second adjustment position Pa2 can be a braking force capable of overcoming the braking force and manually rotating the interlayer paper take-up reel 60.
[0083] [Modifications of the Second Embodiment] In a preferred variation of the second embodiment, the tension adjustment section for changing the tension of the belt 73 may include a distance adjustment section 78, which can movably support the drive motor 71 relative to the rotation axis 74. Figure 7 This is a rear view of the interlayer paper winding apparatus 50, a modified example of the second embodiment. Figure 7 As shown, the distance adjustment unit 78 moves the drive motor 71 relative to the rotating shaft 74, changing the distance between the drive motor 71 and the rotating shaft 74. This changes the tension of the belt 73. Specifically, increasing the distance between the drive motor 71 and the rotating shaft 74 increases the tension of the belt 73. Conversely, shortening the distance decreases the tension of the belt 73.
[0084] like Figure 7As shown, the distance adjustment unit 78 can be configured, for example, to have an elongated hole 78a and a bolt / nut 78b, enabling the drive motor 71 to be fixed at two or more positions with different distances from the rotation axis 74. The distance adjustment unit 78 may also include an actuator for moving the drive motor 71. When the distance adjustment unit 78 includes an actuator, the actuator can be controlled by the control device 90. However, the structure of the distance adjustment unit 78 is not particularly limited.
[0085] [Other Implementation Methods] Some embodiments of the present invention have been described above. However, the above embodiments are merely illustrative, and there are many other embodiments as well.
[0086] For example, in the above-described embodiment, the torque and braking force supplied to the interlayer paper take-up reel 60 are varied by making the connection between the rotating shaft 74 and the interlayer paper take-up reel 60, or between the rotating shaft 74 and the drive shaft 71a of the drive motor 71, a strong connection or a weak connection. However, the method for varying the torque supplied by the drive device to the interlayer paper take-up reel and the braking force when stopped is not limited to this. For example, the drive device may include a drive motor capable of controlling torque.
[0087] Furthermore, the torque provided by the drive device to the interlayer paper take-up reel is not limited to two types. For example, the drive device may also be configured to provide three or more types of torque to the interlayer paper take-up reel, including a first torque and a second torque, wherein the first torque is capable of rotating the terminal tape reel around the support, and the second torque is smaller than the first torque and cannot rotate the terminal tape reel around the support.
[0088] The method for switching between a strong connection and a weaker connection between the drive motor and the interlayer paper take-up reel is not limited to the methods described above. For example, the rotation of the drive shaft of the drive motor can be transmitted to the rotating shaft without a mechanism such as a belt. Alternatively, the rotation of the drive shaft of the drive motor can be transmitted to the rotating shaft via a non-contact power transmission device such as a magnetic gear. For example, in the case of a magnetic gear, the driving force between the gears is transmitted through the magnetic force carried by the gears, and the torque that can be transmitted can be changed by changing the distance between the gears. Furthermore, there are no particular limitations on the method for changing the connection strength between the drive motor and the interlayer paper take-up reel.
[0089] Furthermore, the transmitted torque can be varied while maintaining a secure connection between the drive unit and the interlayer paper take-up reel. For example, the rotation of the drive motor's drive shaft can be transmitted to the rotating shaft via a combination gear with a variable gear ratio. Using this structure, the torque and braking force provided by the drive unit to the interlayer paper take-up reel can also be varied. Moreover, the connection between the drive unit and the interlayer paper take-up reel can be disconnected. In this case, the torque and braking force provided by the drive unit to the interlayer paper take-up reel are zero.
[0090] The structure of the support portion that rotatably supports the terminal tape reel, the crimping device that crimps the terminals to the wire, and the terminal tape feeder that feeds the terminal tape to the crimping device are not limited. Various known devices are preferred as these devices. Furthermore, the structure of the tension detection device is not limited as long as it can detect the force applied to the terminal tape by the terminal tape feeder during terminal tape feeding. Detecting the force applied to the terminal tape by the terminal tape feeder includes not only measuring the force applied but also detecting whether the force applied to the terminal tape by the terminal tape feeder exceeds a predetermined force. Moreover, the structure of the interlayer paper take-up device, such as the shape and arrangement of the various parts of the interlayer paper take-up reel, is not limited as long as the function is achieved.
[0091] The structure and control sequence of the control device 90 for the supply crimping device 10 described above are preferred examples, but are not limited thereto. Unless otherwise specified, the embodiments are not limited to the present invention.
