Description

[Technical field]

[0001] The present invention relates to a tape winding device that rotates a tape winding head around the axis of a wire harness that is transported together with a jig plate, thereby winding a tape around the outer periphery of the wire harness. [Background technology]

[0002] For example, a wire harness installed in an automobile is composed of various parts such as a main line, branch lines, and connectors. This type of wire harness is manufactured through various processes such as wiring electric wires while supporting them on a jig plate with a support member such as a Y-shaped fork, and assembling various parts such as connectors to the electric wires. Generally, in a factory, a large number of wire harnesses are manufactured on an assembly line, so that the wire harnesses are transported together with the jig plate in a fixed transport direction by a transport device such as a conveyor, and the relevant assembly process is carried out at an appropriately determined location.

[0003] These assembly processes include a tape wrapping process in which a tape such as an adhesive tape is wrapped around the wire harness. There are various types of tape wrapping, such as wrapping multiple electric wires or signal wires together to bundle them together, wrapping around the outer periphery of an exterior member (such as a corrugated tube) that houses multiple electric wires, wrapping for identification purposes, and any combination of these. Here, the process of wrapping tape around a predetermined area (straight portion) of the trunk wire will be described.

[0004] As a method for mechanically winding a tape, a tape winding device is known which rotates a tape winding head around the axis of a wire harness which is transported together with a fixture plate, thereby winding tape around the outer periphery of the wire harness.

[0005] In this device, if the jig plate always moves at a constant speed, the tape winding unit located at a fixed position can easily wind the tape at a constant pitch. However, the transport speed of the jig plate may vary (unevenness, etc.) depending on the type of work, etc.

[0006] Therefore, when the winding speed (rotation speed of the tape winding head) is constant, if the moving speed of the jig plate (feed speed of the wire harness) is fast, the winding pitch becomes large and the amount of tape wound per unit length becomes small. Conversely, if the moving speed of the jig plate (feed speed of the wire harness) is slow, the winding pitch becomes small and the amount of tape wound becomes large. In other words, unevenness occurs in the amount of winding depending on the position of the wire harness. In this way, the transport speed of the jig plate often changes due to various factors, and it is difficult to perform high-quality tape winding while adapting to the changes.

[0007] As a countermeasure to this problem, the tape winding device disclosed in Patent Document 1 arranges a tape winding unit at an appropriate position on the conveying path of the jig plate, the tape winding unit being equipped with a winding head that rotates along the circumferential direction of the wire harness (the circumferential direction of the main line) while winding tape around the wire harness, and is configured to move this tape winding unit at a controlled speed along the moving direction of the jig plate.

[0008] In this device, after the tape winding operation at the tape winding start position is completed, the tape winding operation is continued while the moving speed of the tape winding unit is slowed down relative to the transport speed of the wire harness (including stopping the tape winding unit). This creates a speed difference between the wire harness and the tape winding unit, and this speed difference allows the tape to be wound in a spiral shape around the wire harness. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2017-10729 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, if the moving speed of the wire harness is known in advance, the moving speed of the tape winding unit can be calculated before tape winding begins and the tape winding unit can be moved at a controlled speed based on that value. However, there is a problem in that it is not possible to respond if the conveying speed of the wire harness changes during the process.

[0011] One possible solution to this problem is to detect the conveying speed of the jig plate with a sensor or the like and control the moving speed of the tape winding unit based on the data detected by the sensor. However, this requires the installation of extra sensors and calculation means, complicating the configuration and increasing costs. In addition, even if the moving speed of the tape winding unit is controlled based on data detected by a sensor, it is difficult to ensure winding accuracy.

[0012] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a tape winding device for wire harnesses that is simply configured and can easily perform high-quality tape winding without being affected by unevenness in the conveying speed of the jig plate. [Means for solving the problem]

[0013] In order to achieve the above-mentioned object, the tape winding device according to the present invention has the following features (1) to (3). (1) a fixture plate that is transported in a fixed transport direction and supports a portion of the wire harness to be wound with tape while aligning the axial direction of the portion in a direction parallel to the transport direction; a slide base that is provided so as to be movable relative to the jig plate in a direction parallel to a conveying direction of the jig plate, and that moves in synchronization with the jig plate between a preset initial position and an end position; a synchronous setting and releasing mechanism for setting the slide base so as to move in synchronization with the jig plate and releasing the setting; a return movement mechanism that moves the slide base in a direction opposite to the constant transport direction to return it to the initial position when the set by the synchronous set and release mechanism is released after the slide base has moved from the initial position to the end position; a tape winding unit that is provided to be movable relative to the slide base in a direction parallel to a conveying direction of the jig plate, and that rotates a tape winding head about an axis of the portion of the wire harness to be wound with tape, thereby winding tape around the outer periphery of the portion to be wound with tape; a slide drive mechanism for moving the tape winding unit relative to the slide base; a control device that controls the operation of the synchronous set and release mechanism, the return movement mechanism, and the slide drive mechanism; Equipped with the control device controls the relative movement of the tape winding unit with respect to the slide base, the slide base moving synchronously with the jig plate, when winding the tape around the wire harness. Tape winding device.

[0014] According to the tape winding device having the configuration of (1) above, the tape winding unit can be moved relative to the slide base at a constant speed regardless of the conveying speed of the jig plate. Therefore, even if there is an unevenness in the conveying speed of the jig plate, the tape winding unit can be moved relative to the wire harness supported by the jig plate that moves integrally with the slide base at a constant speed. Therefore, regardless of the conveying speed of the jig plate, that is, without having to consider changes in the conveying speed of the jig plate, the tape can be wound around the wire harness at a constant pitch, and good tape winding quality can be obtained. In addition, since the slide base can be made to follow the movement of the jig plate simply by controlling the operation of the synchronous set and release mechanisms, there is no need to provide a mechanism for independently moving the slide base in synchronization with the jig plate, and the configuration can be simplified. Also, since the operation of the tape winding unit is not controlled in response to changes in the conveying speed of the jig plate, no extra sensors or calculations are required, and the configuration can be simplified and easily realized. Furthermore, even if it is necessary to vary the number of wraps depending on the position of the area to be wrapped with tape, each position can be easily identified regardless of the conveying speed of the jig plate, making it easy to control the number of wraps to be different.

[0015] (2) the slide base includes, as the synchronous set and release mechanism, A stopper drive mechanism is provided which, when set, projects a stopper to engage the stopper with the jig plate, and, when released from the set state, retracts the stopper to release the engagement of the stopper with the jig plate. The tape winding device described in (1) above.

[0016] According to the tape winding device having the configuration of (2) above, the stopper is protruded when the jig plate is transported to a predetermined position, thereby engaging the stopper with the jig plate and connecting the slide base to the jig plate, and the slide base can be moved from the initial position to the end position in synchronization with the movement of the jig plate. When the end position is reached, the stopper is retracted to release the engagement of the stopper with the jig plate, and the synchronous movement of the slide base with the jig plate can be released. Therefore, the slide base can be easily synchronized with the movement of the jig plate simply by operating the stopper according to the transport timing of the jig plate.

[0017] (3) The slide base is provided with a gripping mechanism that clamps and prevents the wire harness from vibrating at a position in front of a portion of the wire harness to be wound with tape in the transport direction when the tape is wound around the wire harness. A tape winding device as described in (1) or (2) above.

[0018] According to the tape winding device having the configuration of (3) above, the wire harness is gripped by the gripping mechanism, so that the movement of the wire harness that accompanies tape winding can be suppressed, and tape winding of good quality can be performed stably. Effect of the Invention

[0019] According to the present invention, high-quality tape winding can be performed easily with a simple configuration without being affected by unevenness in the conveying speed of the jig plate.

[0020] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the following description of the preferred embodiment of the present invention (hereinafter, referred to as "embodiment") with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] FIG. 1 is a schematic diagram of a tape winding device according to this embodiment, and FIG. 2 is a side view of the tape winding device.

[0024] 1 and 2, the tape winding device 1 of this embodiment has a jig plate 10 for assembling a wire harness W, and a slide base 20 and a tape winding unit 50 that are arranged in a predetermined work area along the transport path of the jig plate 10. The wire harness W is constructed by attaching various parts 105 such as connectors to electric wires such as a trunk line 101 and branch lines branching off from the trunk line 101, and is assembled on the jig plate 10 that is transported.

[0025] 2, the jig plate 10 is placed in an obliquely inclined position on a frame 12 of a transport device 11 such as a conveyor, and is transported one after another by the transport device 11 in a constant transport direction (direction of arrow A) at a speed Va. A straight trunk wire 101, which is to be the portion of the wire harness W to be wrapped with tape, is supported on the work plate surface (upper surface) of the jig plate 10 in a state where it is extended straight with its axial direction aligned in a direction parallel to the transport direction A. In this case, the portion to be wrapped with tape (trunk wire 101) is supported at its outer ends in the length direction by Y-shaped forks 110 or the like, so that it is supported in a state where it is raised above the work plate surface (front surface) of the jig plate 10 so that the tape can be wrapped around it.

[0026] The slide base 20 is disposed below the jig plate 10 at a position that does not interfere with the work, and is provided so as to be movable relative to the jig plate 10 in a direction parallel to the conveying direction A of the jig plate 10 (arrow B direction). That is, as shown in FIG. 2, the slide base 20 is attached to the front surface of the frame 12 of the conveying device 11 via a slide guide 21. The slide base 20 is provided so as to be able to move in synchronization with the jig plate 10 between a preset initial position and an end position. A synchronization means for this purpose will be described later. Here, the initial position of the slide base 20 is set as a position on the upstream side of the conveying direction of the jig plate 10. Also, the end position is set as a position on the downstream side of the initial position of the conveying direction of the jig plate 10.

[0027] A tape winding unit 50 is attached to the slide base 20 so as to be movable relative to the slide base 20 in a direction (arrow C direction) parallel to the conveying direction A of the jig plate 10. That is, as shown in Fig. 2, a base frame 53 of the tape winding unit 50 is attached to the slide base 20 via a slide guide 22. The base frame 53 is also capable of moving freely on the floor surface by means of casters 52.

[0028] As shown in FIG. 1, a stopper drive mechanism 30 is provided at the front end of the slide base 20 in the transport direction A of the jig plate 10, as a synchronous setting and release mechanism that sets the slide base 20 to move synchronously with the jig plate 10 and releases the setting.

[0029] 3 is a diagram illustrating the configuration and operation of the stopper drive mechanism 30 as a synchronous set and release device. In FIG. 3, (1) to (5) show the states of each part at characteristic timings that change in sequence, and represent the following:

[0030] (1) "Waiting at origin" indicates the state when the slide base 20 is in the initial position (origin). (2) "Detected" indicates the state when it is detected that the moving fixture plate 10 has reached the position where the synchronous set operation starts. (3) "Engaged" indicates a state in which the slide base 20 is connected to the jig plate 10 as a result of the stopper drive mechanism 30 performing a synchronous setting operation. (4) “Disengagement” indicates the state when the slide base 20 reaches the end position through synchronized movement, and at that timing the stopper drive mechanism 30 performs a synchronous set release operation, thereby disengaging the slide base 20 from the jig plate 10. (5) "Return to origin" indicates a state during which the slide base 20 is being returned to the initial position (origin) after synchronization has been released.

[0031] The stopper drive mechanism 30 has an air cylinder 31 fixed to the slide base 20, and a stopper 32 attached to the tip of the rod of the air cylinder 31. The stopper 32 is shaped so as to be able to engage with the front lower end corner of the jig plate 10.

[0032] The stopper drive mechanism 30 is controlled so as to perform a synchronous set operation at a predetermined timing when the front end of the fixture plate 10 in the transport direction approaches the slide base 20 in the initial position.

[0033] 3, (1) "standby at origin", (2) "detection", and (3) "engagement", the stopper drive mechanism 30 engages the stopper 32 with the moving jig plate 10 by protruding the stopper 32 into the range of the movement trajectory of the jig plate 10 (movement of arrow Y1) as a synchronous set operation. This causes the slide base 20 to move synchronously together with the jig plate 10. In other words, the relationship between the speed Va of the jig plate 10 and the speed Vb of the slide base 20 becomes "Va=Vb", and the slide base 20 moves in the direction of arrow B1, which is the same as the conveying direction A of the jig plate 10.

[0034] The timing for executing the synchronous set operation is detected by a timing detection sensor 35 disposed in front of the stopper drive mechanism 30.

[0035] As an example, the timing detection sensor 35 shown in Fig. 3 is composed of an air cylinder 36 and an operating piece 37. The operating piece 37 is disposed at the tip of the extendable rod of the air cylinder 36, and when the operating piece 37 at the tip of the rod in an extended state comes into contact with a protrusion 39 of the moving jig plate 10, it detects that the jig plate 10 has reached the synchronization start position. This detection signal causes the air cylinder 31 of the stopper drive mechanism 30 to protrude the stopper 32.

[0036] Incidentally, this timing detection sensor 35 temporarily retreats the operating piece 37 to the standby position at an appropriate timing after synchronization is established (for example, the same timing as the timing when the stopper drive mechanism 30 retracts the rod of the air cylinder 31 as a synchronous set release operation), and then returns the operating piece 37 to the protruding position again before the slide base 20 returns to its initial position. This is a measure to prevent the protrusion 39 of the fixture plate 10 and the operating piece 37 from interfering with each other when the slide base 20 returns to its initial position, as described later.

[0037] Explaining with reference to Fig. 3, as shown in (4) "disengagement" and (5) "return to origin", when the slide base 20 reaches the end position, the stopper drive mechanism 30 retracts the rod of the air cylinder 31 as a synchronous set release operation (movement of arrow Y2). Then, the stopper 32 retreats to the retreat position (movement of arrow Y2), and the engagement with the jig plate 10 is released. At the same timing, the timing detection sensor 35 temporarily retreats the operating piece 37 to the retreat position (movement of arrow Y3). This is done to prevent the protrusion 39 of the jig plate 10 and the operating piece 37 from interfering with each other when moving the slide base 20 back to the initial position.

[0038] Then, once the engagement has been released, the return movement mechanism 70 (see FIG. 1) returns the slide base 20 to its initial position (origin). That is, the slide base 20 is returned to its initial position by moving in the direction of arrow B2 opposite to the conveying direction A of the fixture plate 10. During this return movement, the stopper 32 and the protrusion 39 are positioned so that they do not interfere with each other. At an appropriate timing when the return movement starts, the timing detection sensor 35 protrudes the operating piece 37 to a detectable position (operation of arrow Y4).

[0039] As a method for detecting that the slide base 20 has moved synchronously with the jig plate 10 and reached the end position, a movement limiter may be provided on the slide base 20, or the point at which the tape winding unit 50 has finished its operation may be recognized as the end position.

[0040] The timing detection sensor 35 described above uses a mechanical sensor (such as a limit switch), but an optical sensor can also be used as the timing detection sensor. For example, a reflector is attached to the jig plate 10 side, and an optical sensor equipped with a light emitting section and a light receiving section is attached to the slide base 20 side. Then, the light emitted from the light emitting section of the optical sensor is reflected by the reflector and enters the light receiving section, thereby detecting that the jig plate 10 has reached a position where the synchronous set operation is performed.

[0041] The return movement mechanism 70 is a mechanism for moving the slide base 20 in the direction opposite to the conveying direction of the fixture plate 10 to return it to its initial position when the slide base 20 has moved from the initial position to the end position and then the setting by the synchronous set and release mechanism 30 is released, and may be a structure using a wire, pulley and motor, or may be a structure using other actuators such as a cylinder.

[0042] Next, the tape winding unit 50 will be described. A known tape winding unit can be used as the tape winding unit 50. As described above, the tape winding unit 50 is provided so as to be movable relative to the slide base 20 in a direction parallel to the conveying direction A of the jig plate 10. The tape winding unit 50 is provided with a tape winding head 55 at the end of an arm that moves forward and backward toward the jig plate 10.

[0043] 4 is a perspective view showing a schematic configuration of the tape winding head 55 of the tape winding unit 50. When winding tape, the tape winding unit 50 advances the tape winding head 55 to the wire harness W. Then, the tape winding head 55 is rotated around the axis of the portion of the wire harness W to be wound with the tape (main wire 101), thereby winding the tape 58 around the outer periphery of the portion to be wound with the tape (main wire 101). That is, the tape winding head 55 rotates along the circumferential direction of the wire harness W as indicated by the arrow R, and winds the tape 58, which has been pulled out from the reel-shaped tape 57, around the wire harness W.

[0044] In addition to the tape winding head 55, the tape winding unit 50 is equipped with a tape cutting mechanism and a wire harness holding mechanism (not shown). The tape cutting mechanism cuts the tape between the tape wound around the wire harness and the reel-shaped tape. The wire harness holding mechanism holds the wire harness on both sides of the tape winding head 55 to prevent it from moving about. These mechanisms perform their designated functions by performing designated operations when necessary, and are provided to retract to a retracted position when not required so as not to interfere with other work.

[0045] A slide drive mechanism 60 is provided between the tape winding unit 50 and the slide base 20 to move the tape winding unit 50 relative to the slide base 20. The slide drive mechanism can precisely control the position and moving speed of the tape winding unit 50 by controlling the drive of a motor (not shown).

[0046] Further, a gripping mechanism 40 is provided on the front end side of the slide base 20 (the front end side in the moving direction of the jig plate 10) for clamping and preventing the wire harness W from vibrating at a position on the front side in the conveying direction of the tape-wrapping target portion (main line 101) of the wire harness W when the tape is wound around the wire harness W. This gripping mechanism 40 also advances only when necessary to clamp the wire harness W between the pair of gripping arms.

[0047] Furthermore, the tape winding device 1 is equipped with a control device (not shown). This control device is for controlling the synchronous set and release mechanism (stopper drive mechanism 30), return movement mechanism 70, slide drive mechanism 60, gripping mechanism 40, tape winding unit 50, etc., and generally executes the following control. Below, we will explain the flow of operations according to the transport position of the jig plate 10 shown in Figure 5.

[0048] First, at the "origin" stage, the slide base 20 is waiting at the initial position. At this stage, the stopper drive mechanism 30 and the tape winding unit 50 are also waiting, and the wire harness W is transported in the direction of the arrow A together with the jig plate 10 at a speed Va.

[0049] When the front end of the jig plate 10 reaches the initial position of the slide base 20, the timing detection sensor 35 described above detects it, and the stopper drive mechanism 30 operates to protrude the stopper (described above). This enters the "engagement" stage. That is, the stopper of the stopper drive mechanism 30 protrudes and engages with the jig plate 10. This causes the slide base 20 to move in synchronization with the jig plate 10.

[0050] Meanwhile, the tape winding unit 50 is moved relative to the slide base 20 in a direction C2 opposite to the conveying direction A of the jig plate 10. Then, the tape winding unit 50, which moves relatively in the opposite direction to the jig plate 10, reaches the winding start position for the wire harness W. At this stage, "winding starts."

[0051] At this "winding start" stage, the tape winding unit 50 advances the tape winding head 55 from the retracted position to the tape winding position, and starts the tape winding operation around the wire harness W.

[0052] Before the tape winding operation starts, the gripping mechanism 40 operates to grip the front end side of the wire harness W so as not to move wildly. Also, the wire harness holding mechanism of the tape winding unit 50 operates to hold the wire harness W in front of and behind the tape winding head 55 so as not to move wildly.

[0053] At the winding start position, the tape winding unit 50 is kept stationary relative to the wire harness W (the tape winding unit 50 is kept stationary relative to the slide base 20), making it possible to wind the tape in one or more overlapping turns.

[0054] Next, in the "mid-winding" stage, tape winding is performed while the tape winding unit 50 is moved at a constant speed relative to the slide base 20 in the opposite direction to the conveying direction of the jig plate 10. This allows the tape winding head 55 to wind the tape while maintaining a constant feed speed for the wire harness W, regardless of the moving speed of the jig plate 10. Therefore, even if there is unevenness in the moving speed of the wire harness W, the tape can be wound at a constant pitch.

[0055] That is, when winding tape around the wire harness W, the tape winding unit 50 is controlled to move relative to the slide base 20 with reference to the slide base 20, which moves in synchronization with the jig plate 10, so that tape winding can be performed without being affected by changes in the moving speed of the wire harness W. For example, the moving speed of the tape winding unit 50 relative to the slide base 20 and the rotation speed of the tape winding head 55 can be determined and controlled without being affected by the conveying speed of the jig plate 10. If the moving speed Vc of the tape winding unit 50 relative to the slide base 20 (the speed in the opposite direction to the conveying direction of the jig plate 10) is made substantially equal to the moving speed of the jig plate 10, the tape winding unit 50 appears to be working at a fixed position, and therefore the casters 52 supporting the tape winding unit 50 can be simplified to some extent.

[0056] In addition, during the "mid-winding" stage, the moving speed of the tape winding unit 50 relative to the slide base 20 and the rotation speed of the tape winding head 55 can be freely adjusted while winding the tape. For example, the speed can be set to low at the start of winding, and then switched from low to high speed midway, or vice versa, and the speed can be set to low where the corrugated tube is located.

[0057] Next, when the tape winding unit 50 reaches the end position, the process enters the "winding end" stage. In this stage, the tape is cut between the wound tape and the tape reel, and the winding head 55 is moved back from the tape winding position to the retreated position, thereby completing the tape winding operation around the wire harness W.

[0058] When the winding operation is completed, the next step is the "return to origin" step. In this step, the stopper drive mechanism 30, which is a synchronous set and release mechanism, is operated to the set release state, and the synchronous movement of the slide base 20 with the jig plate 10 is ended. At the same time, the return movement mechanism 70 returns the slide base 20 to its initial position (movement of arrow B2), and returns the tape winding unit 50 to its initial position relative to the slide base 20 (movement of arrow C1).

[0059] As described above, according to the tape winding device 1 of the present embodiment, the tape winding unit 50 can be moved relative to the slide base 20 at a constant speed regardless of the conveying speed of the jig plate 10. Therefore, even if there is unevenness in the conveying speed of the jig plate 10, the tape winding unit 50 can be moved relative to the wire harness W supported by the jig plate 10 which moves integrally with the slide base 20 at a constant speed. Therefore, regardless of the conveying speed of the jig plate 10, that is, without having to consider changes in the conveying speed of the jig plate 10, the tape can be wound around the wire harness W at a constant pitch, and good tape winding quality can be obtained.

[0060] In addition, since the slide base 20 can be made to follow the movement of the jig plate 10 simply by controlling the operation of the stopper drive mechanism 30, which is a synchronous set and release mechanism, there is no need to provide a mechanism for independently moving the slide base 20 in synchronization with the jig plate 10, and the configuration can be simplified. Furthermore, since the operation of the tape winding unit 50 is not controlled in response to changes in the conveying speed of the jig plate 10, no extra sensors or calculations are required, and the configuration can be simplified and easily realized.

[0061] Furthermore, by projecting the stopper 32 at the timing when the jig plate 10 is transported to a predetermined position, the stopper 32 can be engaged with the jig plate 10, and the slide base 20 can be connected to the jig plate 10, so that the slide base 20 can be moved from the initial position to the end position in synchronization with the movement of the jig plate 10. Furthermore, when the end position is reached, the stopper 32 can be retracted to release the engagement of the stopper 32 with the jig plate 10, and the synchronous movement of the slide base 20 with respect to the jig plate 10 can be released. Therefore, the slide base 20 can be easily synchronized with the movement of the jig plate 10 simply by operating the stopper 32 in accordance with the transport timing of the jig plate 10.

[0062] Furthermore, by gripping the wire harness W with the gripping mechanism 40, it is possible to suppress the wire harness W from moving wildly when the tape is wrapped around it, and it is possible to perform stable, high-quality tape wrapping.

[0063] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0064] Here, the features of the tape winding device for the wire harness according to the embodiment of the present invention described above will be briefly summarized and listed in the following items [1] to [3].
