Description

  The present invention relates to a transmission line braiding device, and more particularly, to a braiding device for a four-wire transmission line comprising two parallel conductors and two conductors knitted into a boot strap (shoelace).

  As a transmission line for transmitting electricity (or an electrical signal) from one end to the other end, a conductive wire obtained by processing a good conductor (conductor) such as copper into a line is generally used. In addition, such a conductive wire is insulated from the outer periphery or coated with an insulator on the outer periphery to prevent contact or short circuit with other conductors.

  Transmission lines using the above-mentioned conductors are constant, such as a transmission line using a single conductor, a TV signal feeder line, depending on the application, that is, the nature of the electricity to be transmitted (voltage, current, frequency, waveform, etc.). A two-wire transmission line that is insulated and held at intervals, a coaxial transmission line that surrounds the outer periphery of the central conductor with an external conductor, and the like are known and widely used.

As for the known transmission line as described above, an optimum transmission line is selected and used according to the characteristics of the electricity to be transferred. However, such a transmission line causes attenuation, transmission delay (phase difference), waveform distortion, etc. that cannot be ignored unavoidably due to the characteristics of the transmitted electricity (signal) and the transmission distance. Therefore, a compensation circuit for correcting such attenuation, transmission delay, waveform distortion, etc. to such an extent that the transmitted electricity (electrical signal) does not cause trouble in its use is required.
Since the compensation circuit as described above is not necessary if it is an ideal transmission line, the configuration is complicated and expensive. Further, for example, a compensation circuit that corrects a delay time (phase difference) delays a signal that is early in time (that is, a phase that is relatively advanced or has a short delay time) to match a signal that is delayed in time. It's just backward compensation.

  Therefore, one of the inventors of the present application previously developed a 4-wire transmission line having remarkable transmission characteristics as compared with an existing transmission line, and on March 15, 2005, Japanese Patent Application No. 2007-066703 “ A patent application was filed as “transmission medium”. This transmission line (4-wire transmission line) has a characteristic configuration such as a 4-wire transmission line composed of four lines L1 to L4 made of a conducting wire as shown in FIG. 1, and has a wide frequency range. It was confirmed by the transmission characteristic test that the transmission characteristic was extremely excellent.

  The manufacture and braiding of the four-wire transmission line as shown in FIG. 1 is not simple, and there is no braiding apparatus that can accurately manufacture and braid the transmission line.

  Then, an object of this invention is to provide the braiding apparatus of the 4-wire transmission line which can manufacture the above-mentioned 4-wire transmission line mechanically and automatically.

The braiding device for a 4-wire transmission line according to the present invention employs the following characteristic configuration.

That is, four-wire transmission lines of high quality (ie, predetermined intervals and pitches set in advance) are automatically manufactured and braided using four conductors supplied from a conductor supply means such as a bobbin. Is possible. Further, by preparing a plurality of pin rollers having different sizes and shapes and exchanging them, it is possible to manufacture and braid four-wire transmission lines having different intervals and pitches. Furthermore, the conductors of a pair of bobbins attached to the top plate so as to be pivotable and the conductor size (conductor length) of the parallel conductor bobbin are preliminarily determined in accordance with the interval and pitch of the four-wire transmission line to be manufactured and braided By making them different, it is possible to automatically manufacture and braid a 4-wire transmission line efficiently with a minimum of downtime (rest period for replenishment of conductors).

  Hereinafter, preferred embodiments of a braiding device for a four-wire transmission line according to the present invention will be described in detail with reference to the accompanying drawings.

  Next, a 4-wire transmission line braiding device according to the present invention for manufacturing and braiding the 4-wire transmission line 100 shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a perspective view showing the overall configuration of a preferred embodiment of the four-wire transmission line braiding device 100 of the present invention. FIG. 3 is an enlarged perspective view of the pin roller portion in FIG. FIG. 4 is a detailed explanatory view of the top plate in FIG. 2, (A) is a plan view of the top plate, and (B) is an explanatory view of a bobbin driving mechanism inside the top plate.

  First, the overall configuration of a four-wire transmission line braiding device (hereinafter sometimes simply referred to as a braiding device) 100 according to the present invention will be described with reference to FIG. The braiding apparatus 100 includes a base (base) 20, a top plate 30, a pin roller 40, and a press roll 50.

  A top plate 30 is attached to the base 20 on a top surface thereof, and bobbins 61-62 for supplying conducting wires for the parallel conducting wires L1-L2 constituting the 4-wire transmission line 10 are attached. A pin roller 40 and a press roll 50 are attached to the top plate 30 via a frame 70. The top plate 30 has a substantially elliptical or rectangular planar shape, and is formed with a substantially “eight-shaped” track 31 as will be described later. Bobbins 63 and 64 for supplying the conductors of the braided conductors L3 to L4 of the four-wire transmission line 10 are attached so as to be movable along the track 31. In addition, elongated rods 65 and 66 are planted at the center positions of a pair of left and right circular portions of the “8” -shaped track 31 of the top plate 30, respectively, and a conducting wire L <b> 1 led out from the bobbins 61 and 62. L2 is inserted. Conductive wires L <b> 1-L <b> 2 exiting from the bobbins 61 and 62 extend toward the pin roller 40.

  In this embodiment, the press roll 50 includes three rollers 51 to 53 that are in contact with each other. Among these three rollers 51 to 53, at least the central roller 52 is formed of a flexible surface material such as urethane. One end portion of these three rollers 51 to 53 is provided with a gear meshing with each other, and is driven to rotate by a drive motor 56 via a pulley 54 and a belt 55. With the configuration of the press roll 50, the three rollers 51 to 53 are rotationally driven in directions opposite to each other, and the four-wire transmission line 10 constituted by the four conducting wires L1 to L4 knitted between them is replaced with 2 The surface including the parallel conductive wires L1-L2 is pressed into a flat four-wire transmission line 10 shown in FIG. The manufactured and braided flat four-wire transmission line 10 is wound, for example, on a reel (not shown).

  Next, with reference to FIG. 3, the structure and operation | movement of the pin roller 40 which is one of the principal parts which comprise the braiding apparatus 100 of the 4-wire transmission line of this invention are explained in full detail. The pin roller 40 is formed to be rotatable about a rotation shaft 41. A number of substantially cylindrical pins 42 are planted at predetermined intervals along the outer periphery of the central portion of the pin roller 40.

  The outer diameter and shape interval (pitch) of the pins 42 formed on the outer periphery of the pin roller 40 are knitted into the interval D of the parallel conductors L1-L2 of the four-wire transmission line 10 shown in FIG. 1 and the parallel conductors L1-L2, respectively. This corresponds to the knitting pitch P of the knitted lead wires L3-L4. Accordingly, the outer shape of the pin 42 of the pin roller 40 is selected to have a size that substantially matches each space S of the four-wire transmission line 10 shown in FIG. The height of each pin 42 (or the dimension protruding from the outer surface of the cylindrical pin roller 40) is such that the adjacent pin is caught by the conductors L1 to L4 during the knitting work of the conductors L1 to L4 described later. It is selected to be low enough not to interfere.

  As shown in an enlarged view in FIG. 3, the four conductors L1 to L4 supplied from the bobbins 61 to 64 are the frontmost pin positions at the center position of the pin roller 40, and the four-wire transmission line shown in FIG. 10 is knitted. That is, the two parallel conductors L1-L2 supplied from the bobbins 61 and 62 are pressed against both sides of the pin 42 (left and right direction in FIG. 3) and maintained in parallel. On the other hand, as will be described later with reference to FIG. 4, two braided conductors supplied from bobbins 63 and 64 that pivot between the parallel conductors L1 and L2 along the substantially “eight-shaped” track of the top plate 30. L3-L4 cross | intersects from the left-right direction between the pins 42, and is knitted into two parallel conducting wire L1-L2. Then, the four-wire transmission line 10 including the four woven wires L1 to L4 is guided to the press roll 50 shown in FIG.

  Next, referring to FIG. 4, it is one of the main components of the four-wire transmission line braiding apparatus 100 according to the present invention, and has the function of weaving the remaining two conductors L3-L4 into the parallel conductors L1-L2. The top plate 30 having the above will be described. 4A is a plan (upper surface) view of the top plate 30, and FIG. 4B is a schematic configuration of a drive mechanism inside the top plate 30.

  As shown in FIG. 4A, the top plate 30 is formed with a track 31 having a pair of circular portions on the left and right of the “8” shape or the infinity symbol (∞) that is substantially rolled over in the figure. At the center position of the left and right circular portions constituting the track 31, an opening 32-33 through which the conducting wires L1-L2 from the bobbins 61-62 are inserted is formed. 4A, the rods 65-66 communicating with the openings 32-33 and the bobbins 63-64 that continuously rotate along the track 31 are omitted for convenience of explanation.

  Inside the top plate 30, a bobbin driving mechanism is provided for rotating the bobbins 63-64 for the conducting wires L 3 -L 4 along the track 31. The bobbin driving mechanism is rotationally driven by a driving source such as a motor, and is disposed in the left circular portion of the track 31 and rotated to the right (clockwise), and the right rotational portion of the track 31 is disposed to the left (counterclockwise). It is composed of a clockwise rotating disk 35 that rotates clockwise. Here, for example, ten nails (finger-like portions) 36 are formed on the left rotating disc 34, and for example, eight nails (finger-like portions) 37 are formed on the right rotating disc 35. The bobbins 63 and 64 are swung around the track 31 by the claws 36 and 37 of the left rotating disc 34 and the right rotating disc 35 along the left and right sides of the track 31 at different speeds. In FIG. 4A, the moving directions of the bobbins 63 and 64 along the track 31 are indicated by arrows.

  According to the above-described four-wire transmission line braiding apparatus 100 of the specific embodiment, the bobbins 63 and 64 pivot on the left side portion of the track 31 at a relatively low speed and the right side portion at a relatively high speed. This moving speed ratio is inversely proportional to the number of claws 36 and 37 of the rotating disks 34 and 35, and is 8:10 (= 4: 5) in the specific embodiment described above, but this value is not necessarily this specific value. It will be readily understood by those skilled in the art that the present invention is not limited and can be appropriately selected.

  Next, the overall operation of the 4-wire transmission line braiding apparatus 100 will be described with reference to FIGS. First, initial operation or terminal processing is performed by manually operating the handles 81 and 82 to guide one end of the four conductors L1 to L4 from the bobbins 61 to 64 to the pin roller 40, the roller 45, and the press roll 50 through the respective paths. I do.

  After the initial manual operation described above, the power source of the drive source such as the motor 56 is turned on, whereby the 4-wire transmission line braiding apparatus 100 described above automatically manufactures the 4-wire transmission line 10 shown in FIG. , Braided and wound on a reel or the like. When any of the bobbin conductors of the bobbins 61 to 64 is used up, the bobbin 61 to 64 is replaced with a new bobbin or the conductors of the bobbins 61 to 64 are replenished, and the above-described initial operation is repeated.

  When the above-described initial operation is completed, the parallel conductive wires L1-L2 supplied from the bobbins 61-62 are arranged in a row on the outer periphery of the pin roller 40 via the left and right openings 32-33 of the track 31 of the top plate 30 and the rod 65-66. Are positioned on both the left and right sides of the pin 42 planted. On the other hand, the remaining two conductors L3-L4 supplied from the bobbins 63-64 are determined by the pitch of the pins 42 of the pin roller 40 by turning around the parallel conductors L1-L2 in a substantially “8” shape. Are knitted around the parallel conductors L1-L2 with a pitch P of

  As described above with reference to FIG. 4, the bobbins 63 to 64 pivot on the determined track 31 at a relatively low speed on the left side and at a relatively high speed on the right side. As a result, as shown in the four-wire transmission line 10 of FIG. 1, the order determined so that the lead L3 from the upper parallel lead L1 to the lower parallel lead L2 intersects below the other lead L4. Knitted with. In other words, at each intersection of the conductors L3-L4, the positional relationship of the conductors L3-L4 is kept constant and knitted.

  The four-wire transmission line 10 constituted by the four conductive wires L1 to L4 knitted as described above is pressed into a flat shape by the rollers 51 to 53 of the press roll 50. In addition, the press roll 50 is given a predetermined tension to each of the conducting wires L1 to L4 being knitted. The manufactured and braided 4-wire transmission line 10 is wound and stored on a reel, and is cut into a desired length according to the application.

  As is clear from FIG. 1, the parallel conductors L1-L2 are substantially linear, but the other two conductors L3-L4 are zigzag between the parallel conductors L1-L2 along the length direction thereof. Wound around. Accordingly, the conductors L3-L4 required for manufacturing and braiding the fixed-length four-wire transmission line 10 are much longer than the lengths of the conductors L1-L2. The ratio (or magnification) of the lengths of the conductors L3-L4 to the lengths of the conductors L1-L2 necessary for the manufacture and braiding of the fixed-length four-wire transmission line 10 is the interval W and pitch of the four-wire transmission line 10 Depends on P. This ratio is directly proportional to the interval W and inversely proportional to the pitch P. Therefore, it is preferable to calculate this ratio in advance and increase the number of conductors of the bobbins 63-64 with respect to the conductors of the bobbins 61-62 to manufacture and braid the 4-wire transmission line 10.

The operation of the embodiment of the present invention will be described below with reference to the simplified drawings.
FIG. 5 shows a simplified apparatus in which only the main parts of the apparatus of FIG. 2 are shown: the bobbins 61 and 62, the top plate 30, the track 31, the bobbins 63 and 64, the rods 65 and 66, the pin roller 40, and the roller 45. FIG.

FIG. 6B is a diagram showing a positional relationship between the pin roller 40 and the pin 42 in the state of FIG.

  FIG. 7A is a diagram showing a state where the bobbin 63 moves in the arrow direction on the track of the left rotating plate, and the bobbin 64 moves in the arrow direction on the track of the right rotating plate. The positional relationship between the four conductors L1 to L4 when the bobbins 63 and 64 are in the illustrated position is as shown in FIG. 7A, and the positional relationship with the pin 42 of the pin roller 40 in the state of FIG. 7A. Is shown in FIG.

  Similarly, FIG. 8A is a diagram showing a state where the bobbin 63 is on the track of the left rotating plate and the bobbin 64 is at the coupling position of the right rotating plate and the left rotating plate. When the bobbins 63 and 64 are in the illustrated position, the positional relationship between the four conductors L1 to L4 is as shown in FIG. 8A, and the positional relationship with the pin 42 of the pin roller 40 in this state is as shown in FIG. ).

  FIG. 9A shows a state in which the bobbin 63 further moves the track and moves from the left rotating plate to the right rotating plate, and the bobbin 64 is also in the position moved from the right rotating plate to the left rotating plate. It is. The positional relationship between the four conductors L1 to L4 when the bobbins 63 and 64 are in the illustrated position is as shown in FIG. 9A, and the positional relationship between the pin roller 40 and the pin 42 in this state is as shown in FIG. ).

  As described above, the bobbins 63 and 64 reciprocate on the tracks of the left and right rotating plates, so that the positions of the conductors L3 and L4 change and are knitted in the form shown in the figure in the pin 42 of the pin roller 40.

  The preferred embodiment of the braiding device for a 4-wire transmission line according to the present invention has been described in detail above. However, it should be noted that such examples are merely illustrative of the invention and do not limit the invention in any way. Those skilled in the art will readily understand that various modifications and changes can be made in accordance with a specific application without departing from the gist and spirit of the present invention.

  For example, in the above-described embodiments, the case where a four-wire transmission line having one type of dimensional shape (parallel conductor interval and pitch) is manufactured and braided has been described. However, if you want to manufacture and braid multiple types of 4-wire transmission lines with different parallel conductor spacing W and pitch P, prepare multiple types of pin rollers according to the transmission line spacing and pitch and replace them. Can be dealt with simply and inexpensively (without substantially changing other components).

  In the above-described embodiments, insulated conductors are used as the four conductors. However, each conductor does not necessarily have to be an insulated conductor, and at least the parallel conductors may be non-insulated conductors. Further, as long as adjacent portions are not contacted or insulated from each other, a non-insulated conductive wire may be used. It is preferable to add tension means for applying a predetermined tension to each conductive wire to be knitted.
