Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically weaving paired wires into a wire holding member to form a guided wireless transmission line.

In order to detect the position of a moving object such as a truck or a crane, a guided wireless transmission line is provided along the travel path of the moving object.

This line has a pattern in which a plurality of pairs of electric wires are crossed at different pitches, and a pattern in which they are twisted together, but conventionally, these arrangements have been done manually.

The present invention provides an electric wire braiding device that can automatically perform crossing and twisting patterns of paired electric wires with one device.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the electric wire knitting sheet A supplied from the supply drum 1 is intermittently fed at a fixed pitch by a fixed length feeding device 2, and A weaving mechanism 3 for weaving the pair of electric wires B and B' onto the sheet A is arranged between the sheet A and the length feeding device 2.

The fixed length feeding device 2 includes, for example, a caterpillar capstan 4 and a one-cyclone motor 5.

Further, its position is not limited to the case shown in the figure, but may be between the supply drum 1 and the knitting mechanism 3.

The sheet A has a pair of wire storage grooves 6.6' in the length direction.
, and a large number of electric wire intersections 7 communicating with this at regular intervals are provided.

Next, on the upper surface of the support stand 10 of the braiding mechanism 3, a pair of electric wires B
A rotary table 12 is attached to which bobbins 11 and 11' for supplying bobbins 11 and 11' are fixed, and this rotary table 12 is rotated by a suitable drive motor 13.

This rotation mechanism may be of any type, but for example, as shown in FIG. 2, the outer periphery of the table 12 is formed into a gear, which is engaged with a gear 14 fixed to the output shaft of the motor 13.

Note that the table 12 is preferably attached to the support base 10 via a thrust bearing 15.

The pair wires B and B' are from the bobbins 11 and 11',
Passage 1 provided in the center of the table 12 and the support base 10
6 and further into the grooves 6, 6' or 7 of the sheet A through guide holes 18, 18' provided in a pair of wire guide rods 17 and 17'.

The guide rods 17 and 17' have the shape of a cylindrical body divided in half along the plane passing through the axis, and have neck parts 19°19/ and 20, 20' on the upper and lower sides, and gears 21 and 20 on the outer periphery of the central part. 2
1' (Fig. 4).

The necks 19 and 20 are rotatably supported by a pair of upper and lower support plates 22 having semicircular recesses 23 having the same diameter.

The neck portions 19/ and 2σ are similarly supported by a support plate 22'.

These support plates 22 and 22' are attached to the support stand 10 so that they can slide in the width direction of the sheet A with their inner sides touching each other, and racks 24 and 22' are provided on their outer sides, respectively. ' is formed.

This rack 24° 24' is provided with suitable drive means 25,
25' pinion 2 rotated by e.g. airmorph
6 and 26' are in mesh with each other, and this drive means 25.25
The guide rods 17 and 17' are moved in the width direction of the sheet A by the operation '.

Note that the guide rods 17 and 17' are support plates 22 and 22'.
However, the half surfaces of the guide rods are pressed against the inner surfaces of other support plates, and rotation is normally prevented.

However, in the position where both guide rods 17, 17' are exactly aligned, they form a complete cylindrical body, as shown by the dashed line in FIG. , 23' are also perfectly circular, so the guide rods 17, 17' can rotate together.

At this time, if a gear 28 rotated by an appropriate drive morph 27 is engaged with gears 21 and 21' formed on the outer periphery of the guide rods 17 and 17', the guide rods 17 and 17' can be rotated at the same time. can.

That is, as shown in FIG. 4, a plate 30 that supports the drive motor 27 and gear 28 is pivoted by a pin 29 attached to a suitable position on the support base 10, and a spring 31 connected to one end of the plate 30 pivots the plate 30. Gear 28 is guide rod 1
The plate 30 is deflected away from the guide rods 17 and 17', and by connecting a driving means such as a solenoid 32 to one end of the plate 30 and operating it, the gear 28 is moved away from the guide rods 17 and 17'. gears 21, 2
1'.

Note that 33 in the figure is a rotation angle detector of the gear 28.

The electric wire braiding device of the present invention has the above configuration, and its operation will be explained next.

Now, sheet A is being fed intermittently at a pitch l in the direction of the arrow in FIG. It is assumed that the grooves are arranged so as to coincide with the cross grooves 7.

The wire guide rods 17 and 17' are normally spaced apart in the width direction so that their lower ends fit into the wire crossing grooves 6 and 6' of the sheet A, respectively.

When sheet A moves, pair wires B and E
¥ is from bobbin 11, 11' to wire guide rod 17, 1
7' and are stored in the wire storage grooves 6 and 6', respectively.

When sheet A stops, the pair of wires B is at that position.

If it is desired to cross the wires B', the driving means 25, 25' of the pinions 26, 26' are operated in the opposite direction, and the wire guide rods 17, 17' are moved along the wire crossing groove 7. Pair wires B and B' intersect as shown at point C in the figure.

Next, when twisting the pair wires B and B', when the sheet A stops, the pinion 2 of only one
6 or 26' and move one wire guide rod to the position of the other wire guide rod, the paired wires B and B' are placed in one wire storage groove 6, as shown at the first point.
Or join 6'.

At this point, as shown by the chain line in FIG. 4, the wire guide rods 17° and 17'Gt are combined to form a cylindrical body, which is rotatable.

Therefore, the solenoid 32 is energized to engage the drive gear 28 and the gear 2L21' on the outer periphery of the guide rods 17 and 17'.

Next, when the gear 28 is rotated at the same time as the sheet A starts moving, the guide rods 17 and 17' are also rotated, and the pair of wires B,
B' is stored in one side of the wire storage groove while being twisted.

At this time, in order to prevent the electric wire itself from twisting, the table 12 of the bobbin IL11' is rotated by the drive motor 13 at the same time, in the same direction, and at the same speed as the rotation of the guide rods 17, 17'.

A one-rotation angle detector 28 is provided in the seventh drive gear 28, and when this detects a predetermined number of rotations, the drive means 27 and the drive motor 13 of the table 12 are stopped, and the solenoid 32 is demagnetized. Gear 28 with guide rod 17
, 17' away from the outer periphery.

Furthermore, one of the drive morphs 25 and 25' is operated,
One of the guide rods 17, 17' is moved in the width direction of the sheet A, and one pair of electric wires is separated from the other as shown at point E in FIG.

By repeating the above operations, the paired wires B and B' are woven into different patterns of crossing and twisting.

According to this invention, as described above, the pair of wire guide rods are
By moving the braided sheets separately in the width direction, they can also be combined into one piece and rotated at that position, making it possible to create different patterns of crossing and twisting pairs of wires with one device. It became possible to knit.

Moreover, since these complex arrangements can be performed automatically without any manual intervention, it is possible to achieve excellent effects in labor saving and cost reduction.
