Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a high-speed double twist twisting machine that has high efficiency, can easily change the twisting ratio, can form strands in any desired state, and has low noise.

[Conventional technology]

Conventional wire twisting machines have a power shaft that runs through the entire mechanism and extracts rotation from it to each flyer rotating shaft.

In addition, in order to arbitrarily select the condition of the strands of the product, when twisting multiple single wires together, the rotation speed of the central single wire and the rotation speed of the multiple single wires twisted around the central single wire are made different. Therefore, it is necessary to install a transmission for each rotating shaft as necessary.

The ratio of the rotation speed of the single wires twisted around it to the rotation speed of the central single wire is called the twist ratio.If the rotation speed of the surrounding single wires is higher than the rotation speed of the surrounding single wires, a tightly tightened strand is obtained. By selecting the return ratio, strands in any desired state can be obtained.

FIG. 6 shows an example of a conventional double twist twisted wire mechanism, in which drive shafts 63 and 64 run between a supply side device 40 and a winding side device 50 via a speed reducer 65.
It is driven by a motor 66. The supply side device 40 consists of a plurality of delivery devices 41, .

The winding device 50 includes a double twisting device 51, 52 is a flyer, 53 is a cradle, and 54 is a winding bobbin. Further, 61 indicates a strand, 62 a set of dice, and 67 a center line of the machine.

Conventional devices like this use a penetrating drive shaft, from which power is extracted to each rotating shaft.
Since it is driven by a single motor M, a reduction gear, a timing belt, a timing pulley, etc. are required, and as the device becomes larger, the rotation of each rotating shaft is required to set the twisting ratio to an arbitrary value. Since the speed must be selected individually, a reduction gear is required for each axis, resulting in large transmission loss and poor efficiency.

[Means to solve the problem]

In this invention, in order to eliminate the above-mentioned conventional drawbacks, the take-up side device and the plurality of supply side devices each have an individual rotating shaft, and a separate drive motor is attached to each rotating shaft. A high-speed double twist twisting machine is provided, which is characterized in that each device can be driven at different speeds, and that the twisting ratio of the supply strand can be arbitrarily determined.

Figure 1 is a front view of the entire double twist twisting machine of this invention, and Figure 2 is a side view, where 1,... are single wires of strands running from the supply side to the winding side, 2 is the supply side device, and 3 28 is the winding side device, 28 is the supply side machine frame,
35 is a take-up machine frame, 36 is a cover, and 25 and 39 are individual motors.

FIG. 3 is an explanatory diagram of the configuration of the supply side device 2, and FIG. 4 is a side view, in which the supply side device 2
It consists of a plurality of single wire sending devices 20, . 1 is a single wire, and 21 is a supply bobbin. Furthermore, in this invention, left and right conical rotary disks 22, 22' are provided in locations corresponding to conventional flyers, and the single wire 1 is passed directly between them.
(Note that these conical rotary disks 22, 22' are shown only in the top single wire delivery device 20 in the right row of FIG. 3, and are omitted in the other delivery devices.)
23 is a roll, and 24 is a batten.

FIG. 5 is a partially cutaway front view of the winding device 3, in which 31 is a winding bobbin, 32 is a strand, 33 is a cradle, 34 is an operation panel, 35 is a machine frame, 36 is a cover, 37 is a set of dice, 38 is a batten, and 39 is a motor.

This invention has such a configuration, and each axis is individually driven by a motor. Normally, a double twist stranding machine twists 7 strands by twisting 6 strands around one central strand, or 12 strands around it.
There are 19 twists for twisting books together, but the main one is
In response to the rotational speed of the main single wire, the rotational speed of the six surrounding single wires, and then the rotational speed of the 12 surrounding single wires, are changed to achieve the desired finished state of the strand. In this invention, each shaft on the supply side is driven by an individual motor, so the desired rotation speed can be easily obtained.

Therefore, as mentioned above, the twisting ratio can be set arbitrarily, and the state where the single wires are tightly twisted together (referred to as a compact state) or the state where the single wires are twisted apart in a cage shape (open (It is called a cord. When used for tire cords, etc., it has the advantage that rubber can fit between the single wires.)
You can do things easily and freely.

〔effect〕

This invention has the above-mentioned configuration, and the twisting ratio on the supply side can be easily and freely selected, the device is compact, and there is little loss of power. Furthermore, since there is no through shaft, the positional relationship between the supply side and winding side devices can be arbitrarily selected.
