It is connected via a lead wire 24a, and further the annular copper plate 23
Each of the above is provided with a current collecting brush 25 having a carbon brush 24 that rotates with the rotation of the reel 13 and slides on the surface of the annular copper plate 23, and further, the current collecting brush 25 and the cord wound on the reel 13. A lead wire 26 is connected to the end of the conductor wire of 14, and the other end of the cord 14 is connected to a wiring terminal in the yarn splicing work carriage 2. The current collecting brush 25 is integrally supported by the reel 13 by a support rod 25a. 27 is a leaf spring for pressing the carbon brush 24 against the surface of the annular copper plate 23, and 28 is a cover for covering the current collector 20.

In FIG. 1, five current collecting brushes 25 are provided, which are three current collecting brushes for using three-phase current and two current collecting brushes for sending various signal currents. A current collecting brush is shown, and it goes without saying that the current collecting brush can be appropriately increased or decreased depending on the scale of the device. Further, it goes without saying that the current collector 20 is not limited to the one having the above configuration.

The biasing device 21 is, for example, as shown in FIG.
The spiral spring 29 has one end 29a connected to the fixed shaft 19 and the other end connected to the work carriage 2 (not shown). The spiral spring 29 is formed by winding a strip-shaped steel material in a spiral shape. It is rotated and the reel 13 is always biased by the spiral spring 29 in the direction of winding the cord 14. Therefore, when the yarn splicing work cart 2 moves in the direction approaching the installation side of the reel 13, the reel 13 rotates in the direction in which the cord 14 is wound up by the urging force of the spiral spring 29. code
The spiral spring 14 and the spiral spring 29 are wound around the reel 13. on the other hand,
When the yarn splicing work cart 2 moves in the direction away from the installation side of the reel 13, the reel 13 rotates in the direction of feeding the cord 14 against the urging force of the spiral spring 29, and the cord 14 and the spring 29. Extend. As a result, regardless of the traveling direction of the yarn joining work carriage 2, the cord 14 can be supplied to the yarn joining work carriage 2 via the reel 13 without slackening.

In the above embodiment, the case where the yarn splicing work cart 2 is supplied with power via the cord 14 has been described.
It is possible to supply and exhaust the yarn splicing work vehicle 2 at the same time as supplying power. That is, in the second embodiment shown in FIG. 5, an air supply passage 30 and an exhaust passage 31 which are opened facing the bottom portion 13a of the reel 13 are provided inside the fixed shaft 19, and the reel 13 is further provided.
At the bottom portion 13a of the connection passage 3 for connecting the end of the hose 32 wound around the reel 13 with the hose joints 33a, 34a.
Provide 3, 34. Needless to say, the other end of the hose 32 is connected to the air supply / exhaust pipe on the yarn splicing work cart 2.

However, there is a slight gap 35 between the peripheral surface of the fixed shaft 19 and the bottom portion 13a of the reel 13, and the gap between the air supply passage 30 and the communication passage 33 and the exhaust passage 31 and the communication passage 34 is annular. It is sealed by the packing members 36a, 36b, 36c, 36d. Therefore, the air sent out from the air supply passage of the fixed shaft 19 stays in the gap 35a sealed by the annular packing members 36a and 36b, so that the air is smoothly introduced into the communication passage 33 even if the reel 13 rotates, and The air sucked from the communication passage 34 is accumulated in the gap 35b sealed by the annular packing members 36c and 36d, and the exhaust passage of the fixed shaft 19 is formed.
It is sucked and removed by 31. The configuration of the power supply unit in the above embodiment is no different from that of the first embodiment shown in FIG.

In the above embodiment, the case where air is supplied to and discharged from the yarn splicing work cart 2 has been described. However, one of them may be supplied with strong air and the other may be supplied with weak air. The hose 32 is shown in the case where one hose is provided with two guide holes, but two hoses provided with one guide hole are used to supply and exhaust air. Needless to say, the configuration may be performed.

In the second embodiment described above, the cord 14 for supplying power and the hose 32 for supplying and discharging air are separately provided, but in the third embodiment shown in FIG. Shows a case in which the cord 14 for power supply and the hose 32 for air supply / discharge are combined into one cord 37. The structure of the power supply unit is the same as that of the first cord shown in FIG. The construction of the air supply / exhaust unit of this embodiment is the same as that of the second embodiment shown in FIG. By changing the design of the cord 14, it is possible to arbitrarily change the number of conducting wires and the number of conducting holes for supplying and discharging air.
Further, a conductor wire and a lead wire 26 are connected to one end of the cord 14, and a conductor hole is connected to a communication passage 38 on the reel 13 via a hose joint 38a, and the other end of the cord 14 is a thread. It goes without saying that they are connected to the wiring terminal and the air supply / exhaust pipe terminal in the joint work vehicle 2, respectively.

Furthermore, the urging device 21 can be constructed as follows. That is, as shown in FIG. 7, the reel 13 is supported by a fixed shaft 19 via a bearing 18, and the outer surface of the reel 13 has a ring-shaped magnet 39 in which S poles and N poles shown in FIG. 8 are alternately arranged. Is stuck. On the other hand, the fixed shaft
A ring-shaped magnet 42 having the same structure as the magnet 39 is provided on one side of the bearing 19 via bearings 40 and 41.
A pulley 43 fixed to the magnets 39 and 42 is disposed so as to face each other, and the pulley 43 is rotated by the rotation of a motor 45 via a toothed belt 44. Therefore, the reel 13 rotates in the same direction as the rotation of the motor 45 by the attraction force of both the magnets 39 and 42.

Therefore, when the yarn splicing work cart 2 moves in the direction approaching the installation side of the reel 13, the magnet 3 is moved.
By the suction force of 9, 42, the reel 13 rotates in the same direction as the rotation of the motor 15 and winds the cord 14 around the reel 13, but the yarn splicing work cart 2 moves in a direction away from the installation side of the reel 13. At this time, the reel 13 slips between the pulley 43 and the attraction force of the magnets 39 and 42, rotates in the direction opposite to the rotation direction of the motor 15, and the cord 14 wound on the reel 13 is removed. Since it extends, it is possible to supply power to the yarn joining work carriage 2 via the reel 13 regardless of the traveling direction of the yarn joining work carriage 2.

Although not shown in the drawing, similarly to the second embodiment shown in FIG. 5 and the third embodiment shown in FIG. Needless to say, the work carriage 2 may be configured to supply and exhaust air.

[0021]

As described in detail above, according to the present invention, the power source is connected to the reel, the reel is connected to the yarn splicing work cart through the cord, and the reel is always wound with the cord. Since it is equipped with an urging device that rotates in a direction, when the yarn splicing work cart travels in the direction close to the reel installation side, the cord is wound on the reel and the yarn splicing work cart is installed on the reel. When traveling in the direction away from the side, the reel reversely rotates against the biasing force in the winding direction, and the cord is unwound from the reel as the yarn splicing work truck travels, and power is supplied to the yarn splicing work cart. Therefore, it is possible to completely prevent the electric shock of the operator, the ignition of the cotton dust due to the spark, etc., as in the case of the conventional power supply by the trolley, and it is possible to obtain a remarkable effect in safety management.
