Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to the production of a woven flat cable in which an arbitrary number of core wires and an arbitrary number of warp yarns are lined up and down in an arbitrary arrangement, and weft yarns are woven into these. It is about the method.

[Prior Art] In conventional woven flat cables, weft threads are woven into core wires and warp threads at a predetermined pitch over the entire length of the cable (for example, Japanese Patent Publication No. 55-38768, Japanese Patent Publication No. 55
(Refer to Publication No.-38787).

Therefore, conventional weaving flat cable manufacturing apparatuses have the same structure as textile looms.

However, in the above-mentioned conventional woven flat cable, when it is cut to a desired length and used, it is necessary to unravel the weft threads at both ends, making terminal treatment troublesome.

Therefore, the inventors of the present invention invented a woven flat cable having a non-woven part, and further improved a conventional loom as a manufacturing device for such a woven flat cable, and developed a weaving machine that weaves the weft into the core wire and the warp. We have invented a weaving machine in which the device and the take-up device for taking up the cord and the warp can be operated separately.

[Problems to be Solved by the Invention] However, in the above-mentioned weaving machine, when forming the non-woven part, the weaving device is stopped and the cord and warp yarns are continuously taken up by the take-up device, so that A large frictional force acts between the core wire and the belt, which may damage the core wire and the belt.

[Means for Solving the Problems] In order to solve the above problems, the method for manufacturing a woven flat cable of the present invention provides an arbitrary number of core wires arranged in parallel in an arbitrary arrangement, an arbitrary number of warp yarns, and an arbitrary number of weft yarns. When manufacturing a woven flat kepul in which a woven part of any length woven at pitch and a non-woven part of any length in which no weft is woven into the core or warp are provided alternately in the length direction, the weaving part When forming the weaving machine, the weaving device of the weaving machine weaves the weft into the core and the warp, and the take-up device of the weaving machine intermittently takes over the core and warp, and when the non-woven part is formed, the weaving device is stopped and , the core wire and the warp are continuously taken up by a take-up device while applying vibration to the core wire.

[Operation] When forming the non-woven part, the cord and warp are taken up by the pulling device without applying vibration to the cord, so that the frictional force acting between the cord and the belt is reduced.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 9.

In the recess 84, the distance in the length direction of the shuttle race 39 is approximately equal to the distance in the width direction of the woven flat cable 1, and the depth is approximately equal to the diameter of the core wire 6 having the largest diameter among the core wires 6. Specifically, the size is, for example, about 220 orders x 6 orders. The four portions 84 are formed over the entire length in a direction perpendicular to the length direction of the shuttle race 39, that is, in depth. The length of the shuttle 40 is set to be at least twice the maximum distance of the distance between the end wall of the recess 84 and the core wire 6 and the distance between the core wires 6. For example, the recess 84
The distance LL between one end wall 84a of the recess 84 and the leftmost core wire 6 in FIG. If there is,
The length L2 of the shuttle 40 is set to satisfy the relationship L2≧2LL. In addition, in FIG. 9, illustration of the warp threads 7 and the weft threads 8 is omitted.

Although not shown, the lead 38 has a large number of steel partition plates in the vertical direction, and the core wires 6 and warp threads 7 are
The woven flat cables 1 are aligned in accordance with the actual arrangement and pass between adjacent partition plates one by one. The distance between each adjacent partition plate is set to be approximately equal to the diameter of the core wire 6 or the warp yarn 7 passing therethrough.

That is, the large number of partition plates are arranged in parallel at irregular pitches depending on the diameters and arrangement of the core wires 6 and the warp yarns 7.

Next, the operation will be explained. A large number of cords 6 supplied by a cord supply device 10 and a large number of warp yarns 7 supplied by a warp supply device 11 are guided by a guide device 12 and distributed between belts 37 and reeds 38 of a weaving machine 13. and is guided between the lower presser roll 43 and the lower presser roll 44. Assuming that the weaving machine 13 forms the weaving section 2, the control device 82 puts the electromagnetic brake device 53 in the brake non-operating state, the tooth-shaped electromagnetic clutch device 66 in the disconnected state, and the second electric motor 64 The actuator 79 and the oscillating device 81 are inactivated, and the first electric motor 47 is activated. The rotational force of the output shaft 48 of the first electric motor 47 is generated between the pulley 49, the belt 52, the pulley 51, and the shaft 5.
0, pulley 54, V belt 57 and pulley 56,
is transmitted to the first crankshaft 55, and the first crankshaft 55 rotates about its axis. As a result, the connecting rod 41
a makes a reciprocating linear motion at a predetermined period, the slay 41 reciprocates by a predetermined angle around the lower end, and the pawl 78 intermittently rotates the ratchet wheel 77 by a predetermined angle via the power transmission mechanism 78a. . The rotational force of the first crankshaft 55 is transmitted to the second crankshaft 5 through a gear 58 and a gear 60.
9, and the second crankshaft 59 rotates around its axis. The number of teeth of gear 60 is twice the number of teeth of gear 58,
The second crankshaft 59 rotates once while the first crankshaft 55 rotates twice. As a result, the connecting rod 37a makes a reciprocating linear movement at a predetermined period, the belt 37 moves up and down alternately, the connecting rod 61a makes a reciprocating linear movement at a predetermined period, and the shuttle drive device 61 drives the shuttle holder 62. The shuttle 40 is then moved in a reciprocating linear motion along the shuttle race 39. That is, one of the two belts 37 for the core wire 6 and the two belts 37 for the warp yarn 7.
One of the belts 37 is raised, the other belt 37 is lowered, and the sley 41 is swung toward the belt 37.
The shuttle 40 is thrown out from one shuttle holder 62 and received by the other shuttle holder 62, so that the shuttle 40 crosses the opening 36 in a direction perpendicular to the core wires 6 and the warp yarns 7, and is housed in the shuttle 40. The weft threads 8 are woven into the core threads 6 and the warp threads 7. Then, the rotational force of the ratchet wheel 77 is transmitted to the lower presser roll 44 via the shaft 68, gear 71, gear 7B, shaft 72, gear 74, gear 76, and shaft 75, and the F section presser roll 44
is rotated by a predetermined angle around its axis. As a result, a predetermined length of the woven flat cable 1 sandwiched between the lower presser roll 43 and the lower presser roll 44 is taken off. Also, core wire 6
The other of the two belts 37 for the warp thread 7 and the other of the two belts 37 for the warp thread 7 rose, one of the healds 37 of each fell, and the slay 41 swung toward the belt 37. state, the shuttle 40 is attached to the other shuttle holder 62
The shuttle 40 crosses the opening 36 in a direction perpendicular to the core wire 6 and the warp threads 7, and the shuttle 40
The weft threads 8 accommodated in the core threads 6 and warp threads 7 are woven.

Then, the woven flat cable 1 sandwiched between the lower presser roll 43 and the lower presser roll 44 is taken off for a predetermined length. Note that when the sleigh 41 swings toward the side opposite to the heald 37 side, it is narrowed down to a predetermined pitch by the weft thread 8 or the lead 38. Thereafter, similar operations are repeated to form the weaving section 2.

On the other hand, the rotational speed of the shaft 68 is detected by a rotary encoder 80, and an output signal of the rotary encoder 80 is supplied to a control device 82. As a result, the control device 82
The length of the weaving flat cable 1 taken up by the lower press roll 43 and the lower press roll 44 is calculated, and when the weaving section 2 has been formed to a predetermined length, the actuator 79 is activated.

As a result, the engagement between the ratchet wheel 77 and the pawl 78 is released, and the lower presser roll 44 no longer rotates. Therefore, the weft yarns 8 are woven into the core wires 6 and the warp yarns 7 at the same position, forming the densely woven portion 4.

After operating the actuator 79 for a predetermined period of time, the control device 82 causes the first electric motor 47 to be inactivated and at the same time the electromagnetic brake device 53 to be activated, and the second electric motor 64 to be activated and the tooth profile electromagnetic brake to be activated. The clutch device 66 is connected, and the actuator 79 and the vibration device 81 are activated. As a result, the rotational force of the output shaft 65 of the second electric motor 64 is transferred to the toothed electromagnetic clutch device 66, the pulley 67, the belt 70, the pulley 69, and the shaft 68.
is transmitted to the lower presser roll 44 via the gear 71, the gear 73, the shaft 72, the gear 74, the gear 76, and the shaft 75, and the lower presser roll 44 rotates continuously, so that the lower presser roll 4
The weaving flat cable 1 sandwiched between the weaving flat cable 1 and the lower pressing roll 44 is continuously taken off. At this time, the first
Since the crankshaft 55 and the second crankshaft 59 do not rotate and the weaving device 33 does not operate, the weft yarn 8 is not woven into the core wire 6 and the warp yarn 7, and the non-woven portion 3 is formed. . In addition, at this time, since the core wire 6 is continuously taken up while the belt 37 is stopped, a large frictional force acts on the heald 37, and there is a possibility that the core wire 6 and the heald 37 may be damaged. As a result of the operation, the connecting rod 81a and the receiver apply vibration to the core wire 6 via the roll 35, so that the frictional force is reduced and damage to the core wire 6 and the belt 37 is effectively prevented. On the other hand, the rotational speed of the shaft 68 is detected by the rotary encoder 80.
The output signal of is supplied to the controller 82. As a result, the control device 82 controls the lower presser roll 43 and the lower presser roll 4.
4, and when the non-woven part 3 has been formed to a predetermined length, the second electric motor 64 is put into a non-operating state, and the tooth-shaped electromagnetic clutch device 66 is put into a non-connected state. Then, the first electric motor 47 is activated, the electromagnetic brake device 53 is activated, and the oscillation device 81 is activated. As a result, a densely woven portion 4 is formed.

Thereafter, similar operations are repeated, and a woven flat cable 1 having alternately woven portions 2 and non-woven portions 3 and densely woven portions 4 at both ends of the woven portion 2 is woven.

When using the woven flat cable 1, the desired length of the woven flat cable 1 is obtained by cutting the woven flat cable 1 at the non-woven part 3, and the connector is connected by applying an adhesive to both ends. Connecting.

In this way, since the vibrating device 81 is provided to vibrate the core wire 6 when forming the non-woven portion 3, the frictional force between the belt 37 and the core wire 6 can be reduced, and damage to the core wire 6 and the belt 37 can be prevented. Can be effectively prevented.

Further, as in this embodiment, the woven flat cable 1 includes a weaving section 2 of arbitrary length in which the weft threads 8 are woven into the core wires 6 and the warp threads 7 at an arbitrary pitch, and the weft threads 8 are woven into the core wires 6 and the warp threads 7 at an arbitrary pitch. A dense weave in which non-woven parts 3 of arbitrary length that are not woven are provided alternately in the length direction, and the core wire 6 and the warp 7 are woven with the weft 8 at the same position multiple times at both ends of each woven part 2. If the portion 4 is provided, by cutting and using the non-woven portion 3, there is no need to unravel the weft threads 8 at both ends during terminal processing, and the terminal processing can be performed quickly. Moreover, non-woven part 3
By providing this, the weft thread 8 can be saved. Further, by providing the densely woven portion 4, fraying of the weft threads 8 at both ends of the woven portion 2 can be effectively prevented.

Further, as in the present embodiment, the weaving flat cable manufacturing apparatus includes a weaving device 33 for arranging a predetermined number of core wires 6 and a predetermined number of warp threads 7 in a predetermined arrangement and weaving the weft threads 8 thereto, and the weaving device The weaving device 33 and the take-up device 34 are provided with a take-off device 34 that takes off the core wire 6 and the warp threads 7 from the weaving device 33 and a control device 82 that controls the weaving device 33 and the take-up device 34.
The weaving section 2 is formed by weaving the weft yarns 8 into the core wires 6 and the warp yarns 7 at a predetermined pitch, and by driving the take-up device 34 without driving the weaving device 33. , by forming a non-woven part 3 in which the weft threads 8 are not woven into the core wires 6 and the warp threads 7, and by driving the weaving device 33 without driving the take-up device 34, the weft threads 8 are woven into the core wires 6 and the warp threads 7 in the same manner. If the structure is such that the densely woven portion 4 is formed by weaving a plurality of times at certain positions, the woven flat cable 1 having the woven portion 2, the non-woven portion 3, and the densely woven portion 4 can be manufactured satisfactorily.

Further, since the woven flat cable 1 can be pulled off faster when forming the non-woven part 3 than when forming the woven part 2, the manufacturing time of the woven flat cable 1 can be shortened as a whole. In addition,
The take-off speed of the woven flat cable 1 when forming the woven part 2 is, for example, 270 in/win, and the take-off speed of the woven flat cable 1 when forming the non-woven part 3 is, for example, 1500 nm/win.

Further, as in this embodiment, the distribution does not use bearings to support the rolls 26 of the guide device 12, and the upper rolls 26 and the lower rolls 26 are arranged alternately to position the rolls 26 in the upper position. If it is supported by the plate 19,
The distribution method simplifies the structure of the guide device 12 and reduces manufacturing costs, and the width of the guide device 12 can be reduced. The bending angle of the core wire 6 as it progresses can be reduced, and damage to the core wire 6 can therefore be effectively prevented. Moreover, since the roll 26 is rotatable, damage to the core wire 6 can be reduced compared to a case where the roll 26 is fixed. Further, the diameter of the cord 6 is much larger than that of the warp 7, and the height of the cord 6 supplied from the cord supply device 10 is higher than the height of the supply of the warp 7 from the warp supply device 11. Since it is arranged above the guide member 31, the core wires 6 and the warp threads 7 do not cross each other on the upstream side of the belt 37, thus effectively preventing entanglement and interference between the core wires 6 and the warp threads 7. can.

Further, as in this embodiment, a recess 84 is formed on the upper surface of the shuttle race 39, and the lengths 1 and 2 of the shuttle 40 are
If the distance between the end wall of the shuttle 40 and the center wire 6 or the distance between the center wires 6 is at least twice the maximum distance L1, the center of gravity of the shuttle 40 will reach one end wall 84a as shown in FIG. When this occurs, the tip of the shuttle 40 always reaches above the core wire 6, and therefore, the tip of the shuttle 40 is effectively prevented from colliding with the core wire 6 and causing the shuttle 40 to stop or deviate from a predetermined movement course. can.

Furthermore, as in this embodiment, if the interval between adjacent partition plates of the lead 38 is made almost the same as the core wire 6 or the warp thread 7 passing therethrough, the width of the woven flat cable 1 can be accurately formed to a predetermined dimension. .

[Another example]

In the above embodiment, the receiver moves the roll 35 to the vibration device 81.
Although the present invention is configured to vibrate and give vibration to the core wire 6, the present invention is not limited to such a configuration, and for example, air may be blown onto the core wire 6 to cause it to vibrate.

Further, in the above embodiment, the woven flat cable 1 is provided with the densely woven portion 4, but the present invention is not limited to such a configuration, and the densely woven portion 4 does not necessarily need to be provided.

Furthermore, in the above embodiment, an example in which no weft yarn 8 is woven into the non-woven part 3 has been described, but the present invention is not limited to such a structure. The weft threads 8 may be woven in two places near the weaving part 2 or the densely woven part 4 in the same manner as in the weaving part 2 or the densely woven part 4, and the center of the two woven parts may be cut at the time of use. In this way, the core wires 6 and the warp yarns 7 of the non-woven portion 3 will not be separated even if they are cut, making handling easier.

Further, in the above embodiment, a belt-type weaving machine 13 was used, but the woven flat cable manufacturing apparatus of the present invention is not limited to such a configuration, and the weaving machine 3 may be a needle-type weaving machine 3. may also be used.

Further, in the above embodiment, the weaving machine 13 is provided with a ratchet wheel 77 and a pawl 78, and the pawl 78 is provided when the weaving section 2 is formed.
However, the weaving flat cable manufacturing apparatus of the present invention is not limited to such a configuration. Alternatively, the second electric motor 64 may be operated intermittently at predetermined timings by the control device 82.

Further, in the above embodiment, the lower presser roll 43 is pressed against the lower presser roll 44 by the spring 46, but the present invention is not limited to such a configuration.
For example, a cylinder device may be used instead of the spring 46.

[Effects of the Invention] As explained above, according to the woven flat cable of the present invention, an arbitrary number of core wires arranged in parallel in an arbitrary arrangement and an arbitrary number of warp threads and weft threads woven at an arbitrary pitch are provided. When manufacturing a woven flat cable in which a length of woven part and a non-woven part of arbitrary length in which no weft is woven into the core wire or warp are provided alternately in the length direction, when forming the woven part, The weaving device of the loom weaves the weft into the core and warp, and the take-up device of the loom intermittently takes over the core and warp, and when the non-woven part is formed, the weaving device is stopped and the core is vibrated. Since the cord and warp are continuously taken up by the take-up device while giving a .
