Description

Technical Field

[0001] The present invention relates to a kasuri yarn binding machine and a kasuri yarn binding apparatus for manufacturing kasuri fabrics such as Kurume Kasuri, Iyo Kasuri, Bingo Kasuri and the like. Background Art

[0002] As one of conventional weaving techniques, kasuri is known, which expresses patterns (designs) by weaving a fabric using warp yarns and weft yarns. The pattern is expressed by regularly arranging blurred-looking portions. Further, kasuri yarns are dyed into two or more different colors, and as a method for this separate dyeing, resist dyeing called binding is known. In addition, as kasuri yarns are also called step-dyed yarns, for example, weft yarns can be bound in two or three steps with binding yarns, so that the bound portions can be dyed separately.

[0003] As techniques for manufacturing kasuri, there are techniques described in Patent Document 1 and Non-Patent Document 1. For example, Patent Document 1 discloses an automatic binding machine for kasuri yarns, which includes a carry-in friction pulley and a carry-out friction pulley for holding a rope of a predetermined length at a predetermined tension, two torque motors connected thereto, two fixing chucks for fixing both ends of the rope of the predetermined length, and a moving table that reciprocates along the rope of the predetermined length, wherein the moving table is equipped with a rope feed chuck, a yarn supplying bobbin for binding yarn, a sizing roller and a binding device.

[0004] In addition, Non-Patent Document 1 describes a technology related to the development of a Kurume kasuri weft binding machine. Non-Patent Document 1 describes reading a blueprint with a kasuri pattern printed thereon, outputting binding information based on the blueprint, and controlling binding #1, binding #2, and binding #3 using a control personal computer.

[0006] [Non-Patent Document 1] Kurume National College of Technology Bulletin 14(1), 5-9, September 1998 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] However, with the increasing diversity of ikat patterns in recent years, there is a growing demand for more convenient ikat thread tying machines. In particular, since the weft threads require more complex dyeing than the warp threads, there is a need for more convenient ikat thread tying machines that can handle this complex dyeing process. Therefore, the automatic tying machine for ikat threads described in Patent Document 1 cannot automatically perform two-stage tying, and thus cannot meet this need. On the other hand, Non-Patent Document 1 describes the development of a weft tying machine for Kurume ikat that can perform up to three-stage tying, but since all three stages (tie #1, tie #2, tie #3) move simultaneously, the tying length is limited, and this also cannot accommodate the diversification of ikat designs.

[0008] Therefore, the present invention aims to provide a more convenient ikat thread tying machine and ikat thread tying device. [Means for solving the problem]

[0009] The ikat thread tying machine of the present invention comprises: a first tying unit that winds tying thread onto the ikat thread based on operation data including a tying start position, winding width, winding direction, and number of windings; a second tying unit that winds tying thread onto the ikat thread based on operation data including a tying start position, winding width, winding direction, and number of windings; and a control unit that independently controls the first tying unit and the second tying unit. As a result, the control unit independently controls the first binding unit and the second binding unit based on the operation data of the first binding unit, which includes the binding start position, winding width, winding direction, and number of turns, and the operation data of the second binding unit, which also includes the binding start position, winding width, winding direction, and number of turns.

[0010] Furthermore, it is preferable that the first tying unit includes a first moving motor for moving the first tying unit along the ikat thread and a first rotating motor for rotating the bobbin of the first tying unit, and the second tying unit includes a second moving motor for moving the second tying unit along the ikat thread and a second rotating motor for rotating the bobbin of the second tying unit. As a result, the control unit independently controls the first moving motor, the first rotating motor, the second moving motor, and the second rotating motor based on the operation data for the first binding unit and the operation data for the second binding unit.

[0011] Furthermore, it is preferable that the ikat thread tying device of the present invention includes a terminal that transmits operation data including the starting position for tying, winding width, and winding direction, and an ikat thread tying machine that receives the operation data from the terminal and transmits to the terminal a response indicating that the process based on the operation data has been completed or a response indicating that a problem has occurred in the process based on the operation data. As a result, based on the operational data from the terminal, the terminal receives information at each stage of the process indicating whether the ikat yarn tying machine completed the process successfully or whether a problem occurred during the process.

[0012] Furthermore, it is preferable that the terminal includes a data generation unit that generates operation data based on the design image and design parameters of the ikat fabric to be produced, and a data transfer unit that transfers the operation data generated by the data generation unit in response to a request from the ikat thread tying machine. As a result, the terminal's data generation unit generates operation data based on the ikat design image and design parameters, and this generated operation data is transferred by the data transfer unit in response to a request from the ikat thread tying machine.

[0013] Furthermore, it is preferable that the data generation unit maps the two-dimensional data of the ikat design image to the one-dimensional data of the weft thread, converts the one-dimensional data of the weft thread into length information of the weft thread, and calculates the starting position for tying based on the shrinkage rate included in the ikat design parameters and the length information, thereby generating motion data. As a result, the data generation unit generates motion data, including the starting position for tying, based on the ikat design image and design parameters.

[0014] Furthermore, it is preferable that the ikat thread tying device has a thread breakage sensor, and transmits a message to the terminal when a malfunction is detected by the thread breakage sensor. This allows the terminal to receive information about the malfunction detected by the thread break sensor. [Effects of the Invention]

[0015] (1) The ikat thread tying machine of the present invention has a configuration comprising: a first tying unit that winds tying thread onto the ikat thread based on operation data including the tying start position, winding width, winding direction, and number of turns; a second tying unit that winds tying thread onto the ikat thread based on operation data including the tying start position, winding width, winding direction, and number of turns; and a control unit that independently controls the first tying unit and the second tying unit. As a result, the control unit independently controls the first tying unit and the second tying unit based on the operation data of the first tying unit including the tying start position, winding width, winding direction, and number of turns, and the operation data of the second tying unit including the tying start position, winding width, winding direction, and number of turns, making it possible to create a wide variety of patterns and realizing a highly convenient ikat thread tying machine.

[0016] (2) Furthermore, the first tying unit includes a first moving motor for moving the first tying unit along the ikat thread and a first rotating motor for rotating the bobbin of the first tying unit, and the second tying unit includes a second moving motor for moving the second tying unit along the ikat thread and a second rotating motor for rotating the bobbin of the second tying unit. With this configuration, the control unit independently controls the first moving motor, the first rotating motor, the second moving motor, and the second rotating motor based on the operation data for the first tying unit and the operation data for the second tying unit, making it possible to create a wider variety of designs and realize an ikat thread tying machine that is more convenient.

[0017] (3) Furthermore, the ikat thread tying device of the present invention has a configuration comprising: a terminal that transmits operation data including the starting position of tying, winding width, and winding direction; and the ikat thread tying machine that receives operation data from the terminal and transmits to the terminal a response indicating that the process based on the operation data has been completed or a response indicating that a problem has occurred in the process based on the operation data. As a result, based on the operation data from the terminal, the terminal receives information on whether the operation process has been completed normally on the ikat thread tying machine side or whether a problem has occurred in the operation process for each process, so that the user can quickly detect a problem that has occurred on the ikat thread tying machine side via the terminal and stop the work midway.

[0018] (4) Furthermore, the terminal has a data generation unit that generates operation data based on the design image and design parameters of the ikat to be produced, and a data transfer unit that transfers the operation data generated by the data generation unit in response to a request from the ikat thread tying machine. As a result, operation data is generated in the terminal's data generation unit based on the design image and design parameters of the ikat, and the generated operation data is transferred by the data transfer unit in response to a request from the ikat thread tying machine. Therefore, as in the conventional technology, there is no need to load a blueprint, and operation instructions to the ikat thread tying machine can be created from predetermined images and parameters, thereby realizing a highly convenient ikat thread tying device.

[0019] (5) Furthermore, the data generation unit maps two-dimensional image data to one-dimensional weft data based on the kasuri design image, converts the one-dimensional weft data into weft length information, and calculates the binding start position based on the shrinkage rate included in the kasuri design parameters and the length information, thereby generating operation data. With this configuration, the data generation unit generates operation data including the binding start position based on the kasuri design image and design parameters, so that a user can easily operate the kasuri thread binding device, and a more convenient kasuri thread binding device that does not depend on the user's skill level can be realized.

[0020] (6) Furthermore, the kasuri thread binding device includes a thread breakage sensor, and when a failure is detected by the thread breakage sensor, the device transmits information indicating the failure to a terminal. With this configuration, information on the failure detected by the thread breakage sensor is received on the terminal side, so that the user can quickly detect failures occurring on the kasuri thread binding machine side including thread breakage and loose thread via the terminal, and can stop work halfway.

[0022] The embodiments of the present invention will be described in detail below, but the description of the constituent elements described below is just one example (representative example) of the embodiments of the present invention, and the present invention is not limited to the following without departing from its gist.

[0023] [Ikat thread tying device] Figure 1 is a schematic diagram of the ikat thread tying device according to an embodiment of the present invention. As shown in Figure 1, the ikat thread tying device 1 has an ikat thread tying machine 10 and a terminal 20.

[0024] Terminal 20 is a device that generates data (operation data) to operate the ikat thread tying machine 10 and transmits (transfers) said operation data to the ikat thread tying machine 10.

[0025] On the other hand, the ikat thread tying machine 10 is a machine that winds tying threads onto ikat threads based on operation data from the terminal 20. Below, the ikat thread tying device 1 (ikat thread tying machine 10) will be described in a form in which tying threads are wound onto the weft threads, but it can also be described in a form in which tying threads are wound onto the warp threads.

[0026] [Terminal] Figure 2 is a schematic block diagram of the terminal. As shown in Figure 2, the terminal 20 has an input unit 210, a display unit 220, a storage unit 230, a data generation unit 240, a data transfer unit 250, and a communication unit 260.

[0027] The input unit 210 is responsible for receiving ikat design information input by the user (the person using the ikat thread tying device 1). The display unit 220 is responsible for displaying the information on the screen of the terminal 20. The storage unit 230 is responsible for storing and saving various types of information, such as memory and databases.

[0028] Kasuri design information includes kasuri design images and design parameters. For example, as shown in Figure 3 (a diagram showing an example of a screen displayed on the terminal), kasuri design images stored in the storage unit 230 can be loaded by specifying the folder path field 210A (see Figure 3(A)). In this case, both the front and back design images of the kasuri can be loaded. Furthermore, as shown in Figure 3(B), users can input the ikat design parameters from the parameter field 210B.

[0029] The data generation unit 240 has the function of generating operation data for operating the ikat yarn tying machine 10. The data transfer unit 250 has the function of transferring the operation data generated by the data generation unit 240 to the ikat yarn tying machine 10. The communication unit 260 has the function of communicating with the ikat yarn tying machine 10. As shown by the dashed arrow in Figure 1, the communication unit 260 allows the terminal 20 to communicate with the ikat yarn tying machine 10 (control unit 130). Communication between the terminal 20 and the ikat yarn tying machine 10 can be achieved using existing technologies such as wired LAN communication or wireless LAN communication.

[0030] The operation data includes the starting position of the tying thread, where it begins to tie the weft thread; the winding width of the tying thread; the winding direction of the tying thread; and the number of windings of the tying thread.

[0031] The terminal 20 can be, for example, a mobile PC, a desktop PC, or a tablet. By running a program on such a PC or other device to operate it as a terminal according to an embodiment of the present invention, and by constructing (implementing) the configuration shown in Figure 2, the user can use the PC or other device as a terminal according to an embodiment of the present invention.

[0032] [Ikat thread tying machine] As shown in Figure 1, the ikat yarn tying machine 10 includes a first tying unit 110 that winds tying yarn onto the weft based on operation data including the tying start position, winding width, winding direction, and number of windings, and a second tying unit 120 that winds tying yarn onto the weft based on operation data including the tying start position, winding width, winding direction, and number of windings.

[0033] Furthermore, the ikat yarn tying machine 10 further includes a control unit 130 that independently controls the first tying unit 110 and the second tying unit 120. The control unit 130 is, for example, a PLC (Programmable Logic Controller). As described above, the control unit 130 can communicate with the terminal 20, and therefore receives operation data transmitted from the terminal 20 and controls the operation of the first tying unit 110 and the second tying unit 120 based on said operation data.

[0034] The ikat yarn tying machine 10 has pulleys P1 and P2 that feed the weft yarn (bundle of weft yarn). One of the pulleys (pulley P2 in the example shown in Figure 1) is equipped with a motor MP, and the motor MP rotates pulley P2 to feed the weft yarn. The first tying unit 110 and the second tying unit 120 are installed between pulley P1 and pulley P2 and are units that tie the weft thread being fed with tying thread. For convenience, the unit on the near side (left side in Figure 1) with respect to the direction of travel of the weft thread being fed is called the first tying unit 110, and the unit on the far side (right side in Figure 1) is called the second tying unit 120.

[0035] The first binding unit 110 includes a first moving motor M11 for moving the first binding unit 110 along the weft direction, and a first rotating motor M21 for rotating the bobbin B1 of the first binding unit 110. On the other hand, the second binding unit 120 includes a second moving motor M12 for moving the second binding unit 120 along the weft direction, and a second rotating motor M22 for rotating the bobbin B2 of the second binding unit 120. Hereafter, the first mobile motor M11 and the second mobile motor M12 may be collectively referred to simply as "mobile motors M11, M12". Similarly, the first rotary motor M21 and the second rotary motor M22 may be collectively referred to simply as "rotary motors M21, M22".

[0036] Furthermore, since the control unit 130 independently controls the first tying unit 110 and the second tying unit 120, it independently controls the moving motors M11 and M12 and the rotating motors M21 and M22, respectively. In other words, the control unit 130 issues different control instructions to these motors regarding the distance to be moved to the tying start position by the moving motors M11 and M12, and the direction in which the tying thread is wound by the rotating motors M21 and M22. Of course, the control unit 130 can also issue the same control instructions (for example, the same direction in which the tying threads are wound by the rotating motors M21 and M22) depending on the design of the ikat weave.

[0037] Furthermore, the ikat thread tying machine 10 includes a thread breakage sensor S1 that detects thread breakage in the first tying unit 110, and a thread breakage sensor S2 that detects thread breakage in the second tying unit 120. The thread breakage sensors S1 and S2 can, for example, detect when the wound tying thread has broken and notify the control unit 130.

[0038] Furthermore, the thread break sensor can also be configured to monitor the tension of the weft thread. For example, as shown in Figure 9, the monitored object moves vertically up and down in accordance with the tension of the weft thread, and the sensor can be configured to monitor the position (height) of this monitored object. When the tension of the weft thread decreases (loosens), the monitored object drops vertically, and the sensor can detect problems in the weft thread, such as thread breakage or loosening, based on the position of this dropped object.

[0039] [Mechanism for tying the weft thread] Figure 4 illustrates the mechanism for tying the weft thread with a tying thread. As shown in Figure 4, it is possible to create patterns for both the front and back using a single weft thread. In other words, by folding the weft thread back at the edge (selvage) to form layers, the front and back are made to appear alternately.

[0040] Then, the front side starts from the starting point of the thread, and it folds back at the right edge (selvage) to begin the back side. Therefore, when the design image is loaded (see Figure 3), the design image information is retrieved from left to right for the front side and from right to left for the back side.

[0041] Figure 5 is a diagram illustrating the mechanism for tying the weft thread with a tying thread, where (A) is a diagram illustrating the tying position of the tying thread, and (B) is a diagram illustrating the winding direction of the tying thread. As shown in Figure 5(A), the tying thread 1 is first wound around the tying position, and then the tying thread 2 is wound around the tying position. In other words, the tying thread 2 is either wound around the weft thread on its own or wound over (part of) the tying thread 1. When the tying thread 2 is wound over the tying thread 1, at the boundary between the tying threads 1 and 2, the tying thread 2 is wound over the tying thread 1 by a certain length.

[0042] Starting from the state in which tying thread 1 and tying thread 2 are wound, (1) Dye the weft threads in a "dark color". (2) Untie the binding thread 2. (3) Dye the weft threads in a "light color". (4) Untie the binding thread 1. By following these steps, The parts that are not wrapped with either tying thread 1 or tying thread 2 (the parts labeled [1] in Figure 5(A)) will be dyed in a "dark color". The part where only tying thread 2 is wrapped (part [2] in Figure 5(A)) will be dyed in a "light color". The areas where only tying thread 1 is wound (part [3] in Figure 5(A)) or where both tying thread 1 and tying thread 2 are wound (part [4] in Figure 5(A)) will have the "base color" of the weft thread.

[0043] Thus, when dyeing the weft threads in three colors—a "dark color," a "light color," and the "base color" of the weft threads (three-color dyeing), two types of tying threads (tying thread 1 and tying thread 2) are used. The starting position for tying and the winding width can be adjusted using the moving motors M11 and M12. On the other hand, the winding direction of the tying threads (left-handed or right-handed) can be determined using the rotating motors M21 and M22.

[0044] [Example of operation] Figure 6 is a flowchart showing the operation of the ikat thread tying device according to an embodiment of the present invention. Figure 7 is a flowchart showing the flow of operation data generation, and shows the detailed flow of operation data generation (step S200) in the flowchart shown in Figure 6. Figure 8 is a sequence diagram showing the communication between the terminal and the ikat thread tying machine in the operation of the ikat thread tying device according to an embodiment of the present invention. The following describes an example of the operation of an ikat yarn tying device according to an embodiment of the present invention, with reference to the drawings.

[0045] First, the user inputs design images and design parameters into terminal 20 (step S100). The input of design images and design parameters is as explained using Figure 3.

[0046] Once the necessary information for generating the operation data has been gathered, the terminal 20 generates the operation data using the data generation unit 240 (see Figure 2) (step S200).

[0047] Here, as shown in Figure 7, the data generation unit 240 converts the vertical pixel count of the input design image into the number of weft threads (step S210). The rows of the design image, as exemplified in Figure 3, correspond to the weft threads. Therefore, by arranging the weft threads vertically, the pattern shown in the design image is created. The value of the number of weft threads (parameter) is referenced from the parameter entered by the user in step S100 and used in the conversion process. Furthermore, in this step, the number of weft threads is matched with the vertical pixel count of the design image in order to map (convert) the two-dimensional data (vertical x horizontal) of the design image to the one-dimensional data of the weft threads, as will be described later. For example, if the vertical pixel count of the imported design image file, such as JPEG or PNG, is 1000 pixels, and the value of the number of weft threads entered by the user is 500, the vertical pixel count of the design image file is converted from 1000 pixels to 500 pixels.

[0048] Next, the data generation unit 240 identifies the colors of the design image (step S220) and then removes noise unrelated to the pattern (step S230). For example, in the case of three-color dyeing, three colors will be identified based on the design image.

[0049] The data generation unit 240 then maps (converts) the two-dimensional data (vertical x horizontal) of the design image to one-dimensional data of the weft (step S240). The data generation unit 240 also calculates the horizontal length per pixel from "horizontal dimension ÷ number of horizontal pixels in the design image" (step S250). The horizontal dimension refers to the parameter entered by the user in step S100.

[0050] Then, the data generation unit 240 converts the one-dimensional data of the weft thread into length information based on the calculated length per pixel (step S260).

[0051] Subsequently, the data generation unit 240 reflects the shrinkage rate of the weft thread (step S270). By following these steps, the data generation unit 240 can calculate the actual dimensions (actual size) of the pattern to be created from the design image and design parameters.

[0052] Finally, the data generation unit 240 calculates the starting position for each color (step S280). As mentioned above, since the dimensions of the pattern to be created can be calculated, the data generation unit 240 can generate operation data including the winding width and winding direction.

[0053] Then, once the generation of operation data is complete, terminal 20 sends a start notification to the ikat yarn tying machine 10, as shown in Figures 6 and 8 (step S300).

[0054] Upon receiving the start notification, the ikat yarn tying machine 10 (control unit 130) sends an operation data request to the terminal 20 (step S311). Meanwhile, the terminal 20 (data transfer unit 250) that received the operation data request transfers operation data for one process to the ikat yarn tying machine 10 (step S312). One step of motion data is a portion of the total motion data required to create the desired pattern. For example, if all motion data is divided into 10 parts, one step of motion data represents 10% of the total progress.

[0055] Meanwhile, the ikat yarn tying machine 10, having received operation data for one process, performs operations based on that operation data. Specifically, the control unit 130 issues control instructions to the moving motors M11, M12 and the rotating motors M21, M22, etc., based on that operation data (see Figure 1).

[0056] Then, the ikat thread tying machine 10 sends a completion report to the terminal 20 indicating that one step of the operation has been completed (step S313).

[0057] When terminal 20 receives a completion report (step S313) and also receives an operation data request from the ikat yarn tying machine 10 (step S311), it transfers the operation data for the next step to the ikat yarn tying machine 10 (step S312).

[0058] In this manner, terminal 20 repeats the operation data transfer process (S310~S320) until all operation data has been transferred to the ikat thread tying machine 10. For example, if all operation data is divided into 10 parts, the operation data transfer from terminal 20 to the ikat thread tying machine 10 will be performed 10 times. In this case, terminal 20 can display the overall progress based on the completion report received from the ikat yarn tying machine 10, as shown in the progress bar 220A in Figure 3(B).

[0059] Once all operation data has been transferred, terminal 20 sends a completion notification to the ikat yarn tying machine 10 indicating that all operation data has been transferred (the work is finished) (step S330).

[0060] Following the procedure described above, operation data is created from the design image and design parameters entered into terminal 20, transferred to the ikat thread tying machine 10, and the pattern is created when the ikat thread tying machine 10 operates based on the operation data.

[0061] The operation data generated by terminal 20 and transferred to the ikat thread tying machine 10 includes the starting position for tying, the winding width, and the winding direction. On the other hand, the number of windings is managed by the ikat thread tying machine 10 (for example, the control unit 130). Of course, information regarding the number of turns may also be created as operation data at terminal 20 and transferred to the ikat thread tying machine 10. The information included in such operation data can be managed (generated and transferred) on the terminal 20 side or managed on the ikat thread tying machine 10 side, and this can be appropriately modified in the design depending on the application of the ikat thread tying device 1.

[0062] In this way, the control unit 130 of the ikat yarn tying machine 10 can independently control the first tying unit 110 (first moving motor M11, first rotating motor M21) and the second tying unit 120 (second moving motor M12, second rotating motor M22), allowing them to perform separate operations. This enables the automatic creation of a wide variety of designs, making it highly convenient.

[0063] Furthermore, unlike conventional technologies that require loading blueprints, this system can create operation instructions for the ikat yarn tying machine 10 from predetermined images and parameters, resulting in greater convenience and improved productivity.

[0064] Furthermore, users can quickly detect any malfunctions that occur on the ikat yarn tying machine 10. For example, if the thread breakage sensors S1 and S2 (see Figure 1) detect that the binding thread has broken, the thread breakage sensors S1 and S2 notify the control unit 130 of this fact. The control unit 130 then sends this information to the terminal 20 as a fault report. The terminal 20 then informs the user of the fault by displaying it on the screen using the display unit 220.

[0065] In this way, when terminal 20 (data transfer unit 250) receives a fault report in step S313 (see Figure 6), it stops transferring any further operational data. Therefore, the user can quickly detect a fault that has occurred on the ikat yarn tying machine 10 and stop the work midway. In particular, in the ikat thread tying machine 10 of the present invention, the first tying unit 110 and the second tying unit 120 are controlled independently. Therefore, the amount of tying thread used for tying may differ between the first tying unit 110 and the second tying unit 120, or different problems may occur at different times. For this reason, rather than transmitting operation data that performs all processes from start to finish at once, transmitting multiple operation data divided by process separately makes independent control of the first tying unit 110 and the second tying unit 120 easier, and allows for rapid detection of any problems that occur in either or both tying units. In other words, by communicating (exchanging) with the terminal 20 of the present invention, the ikat thread tying machine 10 of the present invention, which independently controls multiple tying units, can be appropriately controlled.

[0066] Problems on the ikat thread tying machine 10 side include more than just thread breakage. For example, the motor may fail, the rotary motors M21 and M22 (see Figure 1) may not rotate the required number of times (for example, only rotating 8 times instead of 10), or there may be no tying thread in the bobbins B1 and B2 (see Figure 1).

[0067] In such cases, for example, if the rotary motor fails to rotate a predetermined number of times, it is impossible to tell by visual inspection whether it is working correctly. As a result, users will not know whether the rotary motor is working properly until they have actually woven the entire garment, and may be forced to discard the defective fabric.

[0068] Therefore, by sequentially sending feedback on the operation of the ikat thread tying machine 10 to the terminal 20, the user can quickly detect malfunctions occurring on the ikat thread tying machine 10 and stop the work midway, thereby enabling early resolution of malfunctions (problems).

[0069] Furthermore, even if communication between terminal 20 and ikat thread tying machine 10 is lost, or if the ikat thread tying machine 10 loses power, and therefore no completion report is returned from the ikat thread tying machine 10, the work can be stopped midway in the same manner (step S313 in Figure 6).

[0070] Although embodiments of the present invention have been described above, the embodiments described are merely examples, and the present invention is not limited to these examples without departing from its essence.
