Description

Description: TECHNICAL FIELD The present invention relates to a multi-core wire feeding device for supplying a large number of core wires to a twisting machine or the like for twisting a large number of core wires to produce a twisted wire. .

[Technical Background of the Invention and Problems Thereof] In a conventional multi-core wire feeding device, a full-loading conveyor that loads a fully wound bobbin and supplies the core wire to a twisting machine, and a bobbin of the full-loading conveyor are empty bobbins. A pre-installed conveyor that holds a full-winding bobbin that should be exchanged for them and waits,
And an elevator that communicates between the above conveyors.
Therefore, in the conventional apparatus, the main loading conveyor, the preliminary loading conveyor, and the elevator are independent of each other, and the bobbin transfer operation must be performed by individually operating them. The speed of movement was extremely low.

Further, in order to transfer one bobbin so that one empty bobbin on the main mounting conveyor is taken out and one fully wound bobbin of the preliminary mounting conveyor is transferred to the one mounting conveyor,
It was necessary to determine the conveyor speed according to the time required to take out the empty bobbin. Therefore, it takes about 30 seconds to process each bobbin.

Further, since the mechanism of the elevator (composed of the raising and lowering conveyors) for raising and lowering is complicated, there is a drawback that a failure is likely to occur.

Further, the one in which the preliminary mounting stand provided with the preliminary mounting conveyor and the main mounting stand provided with the main mounting conveyor are separately provided has a drawback that a large installation space is required.

A bobbin loading / unloading bobbin lifter (hereinafter referred to as a bobbin lifter) 12 that is moved up and down by a cylinder 11 is provided.

Thus, the first and second roller chains 1 and 2 and the roller chain rail have the structure shown in FIGS. 2A and 2B.

In FIG. 2A, the first roller chain 1 is constituted by connecting two chain links 14 between the end portions of a plurality of bobbin support bars 13 that rotatably support a roller 13b on a shaft 13a. Has been done. The roller chain rail 15 that guides the roller chain 1 includes the two chain links 14 described above.
Are arranged to be engaged between.

As shown in FIG. 2B, the second roller chain 2 has a plurality of bobbin supports in which rollers 16b are rotatably supported on a shaft 16a having U-shaped rail receivers 16c that open upward at both ends. Bar 16
The end portions of are connected by two chain links 17. A roller chain rail 18 for guiding the roller chain 2 is arranged so as to be engaged between the two chain links 17 described above.

The bobbin supporting bars 13 and 16 are arranged so as to be alternately arranged at intervals smaller than the diameter of the flange of the bobbin 9.

Further, as shown in FIG. 2C, a bobbin mounting pintle 19 is provided facing each bobbin base 10 of the bobbin lifter 12 at a position facing one end of the shaft hole of each bobbin 9 raised by the bobbin lifter 12. A bobbin mounting pintle 20 with a brake is provided at the other end of the shaft hole of each bobbin so as to face each bobbin base 10.

Furthermore, the roller chains 1 and 2 are located between the bobbin support bars of the overlapping portions of the downward running portions 1b and 2b on the motor 5 side,
A bobbin discharging device 21 including a lift lever and the like is provided. In the figure, reference numeral 22 denotes a cylinder that drives the bobbin discharging device 21.

The operation of the device of the present invention having the above configuration will be described below.

First, the downward running portions of the first and second roller chains 1 and 2
As shown in FIG. 3A, both roller chains 1 and 2 are synchronously driven by the motor 5 in the clockwise direction (counter-feed direction) by one pitch to drive 25 to 30 in 1b and 2b (FIG. 1). _One full-roll bobbin B ₁ , B ₁ , ... At this time, each fully wound bobbin B ₁ has a bobbin support bar 13 of the first roller chain 1 and two flanges, as shown in FIG.
It is supported by straddling the bobbin supporting bar 16 of the second roller chain 2.

Next, the fully wound bobbin B ₁ is fully loaded in the overlapping portions of the downward running portions 1b and 2b (FIG. 1), and the motor 5 synchronizes the first and second roller chains 1 and 2 with each other. It is driven in the counterclockwise direction (feed direction). Then, each full-winding bobbin B ₁ is connected to the bobbin supporting bars 13 of both rotor chains 1 and 2,
The flange is supported by 16 and rises to the upper running part.
Move to 1a, 2a side. Here, raise the bobbin lifter 12 and push up each fully wound bobbin B ₁ to move the bobbin mounting pintle 1
9. Operate the bobbin mounting pintle 20 with brake to mount the fully wound bobbin B ₁ . Then, the wire rod is supplied from the fully wound bobbin B ₁ by a well-known means.

While each full-winding bobbin B ₁ is supported by the pintles 19 and 20 to supply the wire rod, another 25 to 30 full-winding bobbins B ₁ are respectively provided to the first and second roller chains 1 and 2. Downward run 1b, 2b
In addition, as described above, the two roller chains 1 and 2 are mounted one by one while being driven synchronously in the clockwise direction (counter-feed direction) by one pitch.

Further, the first and second roller chains 1 and 2 are synchronously advanced by one pitch in the feed direction. That is, as shown in FIG. 3C, the bobbin support bar 16 of the second roller chain 2 is replaced with the bobbin support bar 13 of the first roller chain 1.
Let's get ahead. If this is not done, the bobbin support bars 13, 16 in the upper running portions 1a, 2a will have the bobbin support bars 13 of the first roller chain 1 precede the bobbin support bars 16 of the second roller chain 2 as shown in FIG. 3D. Left as it is,
This is because when the roller chains 1 and 2 move in the feeding direction in this state, the bobbins drop from the bobbin supporting bars 13 and 16.

After that, when the fully wound bobbin B ₁ is supplied with the wire and becomes an empty bobbin B ₀ , the bobbin lifter 12 lowers the bobbin B 1 onto the upper running portions 1 a and 2 a, and the motor 5 drives the first and second roller chains 1 and 2 to move. It advances in the feed direction in synchronization.

After that, the empty bobbin B ₀ sent to the downward running portion advances the bobbin discharging device 21 while moving the first and second roller chains 1 and 2 synchronously by the motor 5 one pitch at a time in the feeding direction.
So that they are discharged one by one.

By repeating such an operation, the wire rod is sequentially supplied to the twisted wire of the new fully wound bobbin.

[Effects of the Invention] As is apparent from the above, according to the multi-core wire feeding device of the present invention, the empty bobbin B ₀ and the fully wound bobbin B ₁ can be easily replaced. Therefore, the operating rate of the twisting machine can be improved.
