Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a device that automatically connects core wires such as communication cables to connectors.

(Prior art) The typical structure of communication cables currently in use is
Shown in Figure 3. As shown in this figure, the thin core wires are blue, yellow, green,
It is insulated with polyethylene colored in eight colors of red, purple, white, brown, and black, and a quad is made by twisting four sets of core wires of these eight colors, and a subunit is made by further twisting five sets of quads. The units are hierarchically arranged in the order of 100 pairs of units, each consisting of 10 sets of subunits twisted together, and all core wires can be individually identified.

(Margins below) Table 1 Among these, for the fibers in a subunit (5-cut, 10-pair, 20-fiber wire), Table 1 is based on the number of the quad to which it belongs and the color of the core itself. Core numbers are assigned as shown in the figure below.

Moreover, FIG. 14 is a diagram showing the relationship between the shape of the core wire and the connector. FIG. 14(a) is a diagram showing a state when one subunit, that is, 20 core wires 2 are connected to one connector 1, and the core wires 2 are bent at 90 degrees near the connector 1. There is.

Since the communication cable is composed of several thousand core wires 2, the connecting portion is considerably large compared to the thickness of the cable. Therefore, the connector 1 for communication cable has the following features: the size of the connection part can be reduced, a large number of connectors 1 can be easily stored, and the electrical characteristics are good (--If the connector is made large in the membrane, the electrical characteristics will be improved. easier to do)
There are contradictory requirements. FIG. 14(b) is a diagram showing the shape of the connector connection part when the core wire 2 is bent at 90 degrees and when the core wire 2 is not bent at 90 degrees. It can be seen that this makes it possible to reduce the size of the connecting portion and to facilitate the storage of a large number of connectors 1. Therefore, as a means to reduce the size of the connection part while keeping the size of the connector 1 constant, the core wire 2 is
As shown in Figure 4(a), it is bent at 90 degrees.

Conventionally, when connecting a cable, specifically a connector to the tip of a subunit, the subunit is divided into quads, and the quads are divided into cores from higher to lower hierarchy, and then each core is connected to a predetermined location within the connector. placed and connected in position.

Until now, there have been no proposals for a device that would automate the division, placement, and connection of core wires, and everything had to be done manually, so it took about 20 hours to connect 3,000 pairs of cable core wires. was. In addition, erroneous judgments occurred when identifying the color of the core wire, and especially when the user became tired, it became often impossible to distinguish between yellow and white. Furthermore, the work was done in dark manholes or in high places such as on top of pillars, making the work hard and arduous.

(Problems to be Solved by the Invention) As mentioned above, since a large number of connectors are used to connect cables, the connection part is large, and the connection work requires many workers and time, and is prone to errors. There is also a need for judgment, and automation of this process is desired.

However, in order to make the connecting portion smaller, it is necessary to bend the core wire at 90 degrees and shape it, which, along with the work of untwisting the core wire, has hindered automation.

(Example) The present invention will now be described in detail by way of example with reference to the drawings.

To explain the first embodiment, the overall configuration thereof, as shown in FIG. 1, includes an untwisting section 11, a wire number identification section 12,
It is composed of a connecting portion 13 and other known drive devices, control devices, etc. (not shown).

The untwisting section 11 includes a main body 22 having an operation table 21, and five operation holes 23 are provided radially in this body. Further, an operation bottom plate 24 that closes the bottom of each operation hole 23 is rotatably attached to the lower surface of the operation table 21. This operation bottom plate 24 is provided with a core wire receiving surface 25 at a position corresponding to the operation hole 23, and further provided with a separating groove 26 consisting of four parallel grooves adjacent thereto. The operating bottom plate 24 is rotated back and forth as needed by a driver (not shown).

Regarding the relationship between the operation hole 23 and the cable to be processed, the cable 6 is connected to the unit 5 in FIG.
, subunit 4, and further divided into five sets of quads 3, which are accommodated in respective operation holes 23 and placed on an operation bottom plate 24. Each quad 3 is constructed as shown in Table 1, and each quad 3 is composed of four core wires 2. The five quads 3 are fixed by clamps 27 at the center of the dowels, and the open ends 28 are on the outside.

In addition, in the case of a communication cable, the diameter of the core wire 2 is 0°32.
There are 0.4, 0.5, 0.65, 0.9mm types,
The twisting pitch varies depending on the wire diameter, but is approximately 2 to 8 cm.
It is.

Further, the slider 31 is inserted into the guide body 32 in the operation hole 23.
It is set up so that it can be moved freely while being guided by.

This is driven forward and backward and up and down as shown by arrows 33 and 34, but when moving forward toward the release side 28, it is pushed downward and sent, and when moving backward, it is separated upward and returned. It is operated as follows.

As a result, when moving forward, the quad 3 is slid while being pressed, thereby acting to untwist it. This will be described later, but the four core wires 2 (
The operation holes 23 (20 in total) are further pressed and slid so that they are aligned one by one with the separation grooves 26 that have been moved by rotation. At this time, the separation groove 26 has a wave-shaped cross section so that the core wire 2 can easily enter the separation groove 26, and further vibrates from side to side. The slider 31 is operated by a drive means (not shown), but any drive means with an appropriate pressing force may be used.

Next, the wire number identification section 12 will be explained. It consists of identification means 41 and array transfer means 42.

The identification means 41 includes a color sensor 45 that detects colors, and a storage device 46 that stores and processes future detection signals. Further, the separation groove 26 is provided with multiple detection holes 47 for color identification, and punch holes 48 are provided correspondingly adjacent to these holes. Punches 49 are attached below these punch holes 48 in correspondence with each other, and these punches are raised by commands from the storage device 46 to push up the core wire 2. In addition, the detection hole 47
Below, a guide body 50 extends across each operation hole 23, and by moving the color sensor 45 along this guide body 50, the colors of the 20 core wires 2 accommodated in all the separation grooves 26 are detected. The information is stored in storage 46 along with its arrangement.

Next, the arrangement transfer means 42 includes an annular body 52 that is rotatably supported by a column (not shown) apart from the operation table 21, a drive body 54 that rotates the annular body 52 with a gear 53, and a drive body 54 that is attached to the annular body 52. Transfer holder 5
It consists of 5. This transfer holder 55 is made of a comb-like member and has 20 support grooves 56 for holding the core wire 2 when inserted. This is the annular body 52
The punch hole 48 of the separation groove 26 and the support groove 56 are opposed to each other, and the core wire 2 is moved and stopped at a position where the punch hole 48 of the separation groove 26 faces the support groove 56, and the core wire 2 pushed up by the punch 49 is received and held in the support groove 56. This movement and stopping is based on commands from the storage device 46, and by operating the commands, all the core wires 2 are arranged and held in a predetermined order and transferred to the connection section 13.

Next, the connection portion 13 will be explained. This consists of a wire array body 62 consisting of a pair of comb-like members having a slit 61 slightly wider than the diameter of the core wire 2, and a wire holding body consisting of a pair of comb-like members that are moved up and down by a driver 63. 64, a shaping presser body 66 made of a comb-like member that is moved up and down by a driver 65, and a shaping body 68 that is made of a comb-like member that is moved up and down and back and forth by a driver 67.

Note that each of these parts will be explained along with their functions.

This first embodiment is constructed as described above, and its operation will now be explained.

First, after setting this device in the predetermined position,
The subunit 4 is arranged as shown in FIG. 2 by cutting off the end of the subunit 4, fixed to the operation table 21 with a clamp 27, and the quad 3 is placed in each operation hole 23. In this state, the subunit 4 and the quad 3 are in a twisted state.

FIG. 3 shows the mechanism and procedure for untwisting the core wire 2.

By applying appropriate pressure with the slider 31 and squeezing the twisted quads 3 toward the open end 28,
Quad 3 is untwisted. However, when the length of the quad 3 is long, the twist of the quad accumulates toward the open end 28 of the quad 3 while the slider 31 is slid, and the twist eventually returns in a dumpling shape. It's gone. Therefore, as shown in FIG.
The untwisting length is approximately the twist pitch of quad 3, and by repeating this, the long quad 3 is untwisted. Also, during these series of repetitions, the operation bottom plate 24 is
By vibrating in the vertical direction, it is possible to further reduce the risk of the twist forming into a dumpling shape due to the curl of the core wire 2 or the like.

That is, while vibrating the operating bottom plate 24 in a direction perpendicular to the core wire 2, the slider 31 moves from a point about one pitch away from the open end 28 of the quad 3 as shown in FIG. 3(a). After reaching the open end 28 of the quad 3 as in b),
The slider 31 is lifted from the quad 3 as shown in FIG. 3(C), and in that state is moved to a point about two pitches away from the open end 28 of the quad 3, and as shown in FIG. 3(d). From that point, an appropriate pressure is applied to the slider 31 to make it slide in the direction of the open end 28 in the same way as the first time, thereby untwisting it by one pitch. FIGS. 3(e) and 3(f) are the repetitions.

Furthermore, FIGS. 3(g), 3(h), and 3(i) are diagrams showing a method of arranging the core wires 2 in a predetermined position in an arbitrary order after the quad 3 is untwisted. Rotating separation groove 2
6 moves below the core wire 2.

In this state, the slider 3 is moved while vibrating the operation bottom plate 24.
1 toward the open end 28, the core wire 2
are aligned in the separation groove 26. In addition, by making the bottom of the slider 31 wave-shaped, comb-shaped, etc. at predetermined intervals (intervals between core wires, intervals between separation grooves), it becomes easier to untwist the quads 3 and align them to the separation grooves 26. .

FIG. 4 is a diagram showing a method for identifying the core number by the color of the core wire 2. The quad 3 shows an example in which the core wire 2 is composed of four wires, but in the case of a communication cable, as shown in FIG.
The colors are blue, yellow, green, red, and purple. The identification procedure samples the color of core wire 2, performs color identification,
After storing the 20 results in the storage device 46, the core number is identified from this information. The method to identify the wire number is 20
Color information of 1~4.5~8. ......, 17-2
Divide wires into groups of 4 like 0, look for blue, green, red, and purple in each group, identify the number of quad 3, and then write the wire number from the white, brown, and black information in Table 1. Identify according to. Therefore, in the case of this method, it is necessary that the core wires 2 do not cross between the quads 3. In FIG. 4, one quad 3 is temporarily fixed with a clamp and a slider 31, and a guide body 50
A color sensor 45 moves above to perform color sampling. Sampling and color identified color information is sent to the signal line 45
a and then processed.

In this way, the fiber numbers of the 20 five-force wires are identified.

After the untwisting process of the quad 3 and the fiber number identification process are completed, a process of arranging and holding the subunits, that is, the 20 core wires 2 in a predetermined order is started. FIG. 5 shows an embodiment of the invention, in which a transfer holder 55 has 20 support grooves 56 having a width approximately equal to or slightly narrower than the diameter of the core wires above the core wires 2 which are twisted back into a parallel state. is moved to the position corresponding to the wire number via the annular body 52, and the core wire 2 is pushed up by the punch 49 and pushed into the support groove 56 at the position corresponding to the wire number. At this time,
As described above, the position adjustment is performed by the storage device 46 and the driver 54. In this embodiment, four punches 49 are arranged for each untwisted quad 3, and five sets of punches are arranged. Therefore, since the untwisted core wires 2 and the punch 49 are immovable, one core wire Each time, the transfer holder 55 moves and arranges the core wires 2 in a predetermined order.

Next, the process of connecting the aligned core wires 2 to the connector is started. FIG. 6 shows the shape of the core wire 2 when the core wire 2 is connected to the connector. The core wire 2 is 90 as shown in Figure 14.
Since the parts are bent and connected, it is necessary to form them in this way.

Figure 7 shows how the core wires 2 are received and transferred, Figure 8 shows how to bend the core wires 2 at 90 degrees and form them so that they are lined up at regular intervals, and Figure 9 shows how the connectors 1 are press-fitted. FIG. 4 is a diagram showing a method of connecting the connector 1 by cutting off the excess core wire. In FIG. 9, 1a is the body of the connector 1, 1b is a cover, and 70 is a cutter. Figure 7 (
When the core wires 2 arranged and held as shown in a) and (b) are pushed into the transfer holder 55, 20 slits 61 slightly wider than the core wire diameter are formed inside the transfer holder 55 and 20 slits 61 are formed outside the transfer holder 55. is moved onto the core wire array 62 having 20 core wires.

When the wire is moved, the wire holding body 64 descends and transfers the wire 2 from the transfer holder 55 to the wire arraying body 62, and further presses down the wire 2 with a constant force. line 2
Apply a certain tension to the

FIG. 8 is a diagram showing the step of wiring the core wire 2 to the connector 1 in the process of connecting the core wire 2 to the connector 1, and shows a shaped body 68 having a slit 68a wider than the core wire diameter and a slit. Wiring is performed by moving the shaping presser body 66 having 20 pieces 66a. The tips 68b of the shaping body 68 are lined up on the circumference so that they can easily fit into the gaps between the radial core wires 2, and the bases 68c are lined up in a straight line for wiring to the connector 1. In addition, the slit 6 of the shaping presser body 66
6a are arranged in a straight line. The core wire 2 is shaped according to the following procedure. First, in order to facilitate shaping, a certain tension is applied to the core wire 2 by the core wire pressing member 64, and the tip 68b of the shaping member 68 is placed between the core wires 2 as shown in FIG. 8(a). and move it diagonally upward. As a result, the contact portion with the core wire 2 moves from the tip 68b to the root 68c. Next, by moving the shaping body 68 horizontally as shown in FIG. 8(b), the core wire 2 is bent at approximately 90 degrees as shown in FIG. 8(C), resulting in a shape similar to that in FIG. 6. .

In order to accurately bend the wire to 90 degrees, move the shaping presser body 66 downward to stop the core wire 2 as shown in FIG. 8(d), and then return the shaping body 68 to the same position as in FIG. 8(b). Especially the 8th
As shown in Figure (e), the core wires 2 are bent at 90 degrees and arranged at regular intervals.

FIG. FIGS. 9(b) and 9(C) are diagrams showing the process of cutting off the excess core wire 2 by the cutter 70, and thereby the connector is connected as shown in FIG. 14(a).

The cable core automatic connection device according to this embodiment is a device having the means described above.

An advantage of this embodiment is that, unlike the conventional method of manually attaching connectors to cables, connectors can be connected by machine after subunits are set in each quad.

Next, a second embodiment will be explained.

FIG. 10 is a diagram showing a second embodiment of the present invention. 1st
Figure 1 shows the preparation process performed manually when performing cable core wire connection work according to the present invention, and shows the arrangement of cables, etc., including a cable 6, a unit 5, and a subunit 4.
It shows the positional relationship of

In FIG. 10, reference numeral 129 is a U-slit for establishing conduction with the core wire, which will be described later as an identification signal detector, 130 is a hole for accommodating the subunit 4, and 131 is a U-slit for connecting the mutually twisted quads 3 to the subunits. A slider 132 for returning is an operation bottom plate that vibrates in the circumferential direction, and the U slit 12
Detection hole 132b for detecting an electric signal by 9
, a separation groove 13 for organizing the core wires 2, which has punch holes 132C for aligning and holding the core wires 2 with a punch.
It has 20 pieces of 2a. Reference numeral 133 denotes a core wire holding body that holds down the core wire 2 when establishing conduction with the core wire 2 through the U-slit 1-29.

The second embodiment of the automatic cable connection device according to the present invention has the structure as described above, and is operated by the following procedure. After setting this connection device in the specified position, cut off the end of cable 6 and connect it to subunit 4.
are arranged as shown in FIG.

In FIG. 11, 27 is a clamp for fixing the subunit 4 to the operation table 130a.

At this time, the subunit 4 is in a twisted state.

The principle of the mechanism for untwisting the core wire is the same as in the first embodiment,
A slider 131 and an operation bottom plate 132 are used instead of the slider 31 and operation bottom plate 24 of the first embodiment. The difference between the two embodiments is that in the second embodiment, the subunits 4 are untwisted all at once, so there is a risk that the core wires may cross between the quads 3, and the pressure applied to the slider 131 is increased. It is. FIG. 12 is a diagram showing a means for identifying a core number by an electrical signal, and shows the second embodiment and the first embodiment.
The characteristic difference from the embodiment described above is this core number identification means. In FIG. 12, 134 is a connector attached to one end of the cable 6 and is an identification signal transmitter, and 135 is an electric signal that is different for each core wire. This means is a means for identifying the core number by an electrical signal instead of the wire number identifying means by color shown in FIG. 4 of Embodiment 1. A signal 135 (specifically, a different frequency) is sent from a connector 134 that has been manually attached to one end of the cable 6, and a U-slit is made at the end where the connector connection is made. -129 to establish continuity with the core wire. The electric signal is transmitted from the U slit 129 to the signal line 45a.
The data is stored in the storage device 46 through. Since the stored information is 20 different pieces of information, wire number identification can be easily performed. In addition, crossing of the core wires between the quads 3, which was a drawback of the color-based identification method, is also allowed. In this way, the 20 core numbers are identified. After the untwisting process of the quad 3 and the fiber number identification process are completed, a process of aligning and maintaining the subunit 4, that is, 20 core wires 2 in a predetermined order, and a process of connecting the aligned core wires to the connector are performed. conduct. These two steps are exactly the same as in the first embodiment. In this way,
The connector is connected as shown in FIG. 14(a).

The cable core automatic connection device according to this embodiment is a device having the means described above. The effect of this device is that the conventional process of manually attaching connectors to both ends of a cable only needs to be done on one end, and the other end can be connected by machine after the subunit is set. .

[Effects of the Invention] As explained above, the cable core wire automatic connection device of the present invention automatically connects the core wires of communication cables and the like to the connectors, thereby significantly reducing the number of workers and work time. can. For example, the time required to connect 3,000 pairs of cable core wires can be reduced by 20 hours, and there is no misjudgment of color when fatigued.
Furthermore, it greatly contributes to the reduction of heavy and arduous work inside manholes and on pillars.
