[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is a power feeding device, particularly a doffing trolley for feeding power to doffing trolleys that run between a plurality of drawn false twisting machines and perform doffing work of each false twisting machine. Concerned.

[0002]

[Prior art]

 In a draw-stretching combustor, a yarn is guided from a large number of packages supported by a creel stand to a ceiling direction through a feed roller and a primary heater, and the yarn is arranged opposite to the creeper stand with a space provided therebetween. After passing it to a false twisting device consisting of a cross belt provided above the wire, heat treating the yarn after false twisting through a secondary heater provided in the frame of the false twisting device, and applying oil on the oiling device provided below, It is guided to the front surface of the false twisting device frame, that is, the side surface facing the creel stand, and is wound into a package rotatably supported on this surface.

A large number of draw false twisting machines having the above-mentioned configuration are adjacent to each other to form a first draw false twisting machine row, and a second draw false twisting machine row of the same configuration is arranged back to back on the back surface of the false twisting machine frame. Furthermore, a stretch false twisting machine row of the same configuration is arranged back to back on the back of the creel stand of the second stretch false twisting machine row, and by repeating the same arrangement, a multi-row stretch false twisting machine block is formed. Many such blocks are placed in the false twister factory.

In the draw false twisting machine of each row, the distance between the creel stand and the false twisting machine frame is a branching runway of a doffing carriage for doffing the package wound on the entire surface of the false twisting machine frame. The doffing trolley runs between adjacent drawing false-twisting machines to take out the fully wound package and replace it with an empty paper tube. This doffing trolley travels on one main traveling road arranged at the side end of each row of the above-mentioned drawing false twisting machines arranged back-to-back with each other. From the branch station at the side end position of the twisting machine, the train runs on the branch runway of each row above, and the doffing operation is performed in each row. After the doffing work is completed, it returns to the branching station again, travels along the main running path, stops at the branching station in the next row, and enters the branching running path branching from there to doffing work. By repeating such running and work, one doffing cart carries out doffing of one block of the draw false twisting machine.

Further, in order to reduce the number of branching stations arranged on the main traveling path and to simplify the branching station, the false twisting device frame rows that are back to back are formed as a pair of rows, and the side ends of the pair of rows are formed. By arranging one branching station in the section, and by providing a transfer path from this branching station to the branching roads in the left and right rows that are arranged back-to-back, the doffing truck on the main running road stopped at the branching station Of the left and right transfer paths that extend to the left and right and connect to the left and right branch travel paths, first run the transfer path (right transfer path) to the one side (for example, right side) of the branch travel path. , Transfer to the branch road, doffing that line, reverse the run and return to the branch station again, if necessary, transfer path to the other side (left side) branch road (left transfer) Road) It has been proposed to move to the running path, do the doffing work on the back side of the previous line, run backward after the work, return to the branch station, and then run to the next branch station.

On the other hand, the doffing dolly requires power supplies for motors for driving and doffing work and various electromagnetic devices and control devices, and stacking the power supply on the dolly increases weight and size. Therefore, power is supplied from the outside by a power cable. Since the doffing truck travels vertically and horizontally on a main road and each branch road in a wide block, a suspension rail is installed above the main road so that the power supply cable does not get caught in various devices. One cable is placed and the cable take-up reel is hung on this suspension rail, and the cable take-up reel is running just above the doffing trolley running on the main running path with the cable taken up in the shortest distance. . When the doffing dolly stops at the branching station and travels further on the branch traveling path from the left and right transfer paths, it feeds the power supply cable from the cable take-up reel stopped at the upper part of the branching station. The feeding cable sent from the take-up reel is supported by a cable support roller provided along the runway of the doffing cart to prevent it from falling to the floor due to its own weight. When finishing the doffing of the false twisting machine and returning to the branching station again, the cable take-up reel winds the extra length of the feeding cable. Next, in order to perform doffing work of the drawing false twisting machine on the back side row, when the doffing trolley runs, the cable take-up reel again sends out the power feeding cable and repeats the same operation.

[0007]

[Problems to be solved by the device]

 In the above-mentioned draw false twisting machine, for a doffing trolley traveling on the main traveling route, a cable take-up reel that is hung from a suspension rail arranged above the main traveling route and runs together with the doffing trolley. There is no problem because the power supply cable extends from the power supply cable, but when the doffing cart stops at the branch station, moves to the transfer path, and starts traveling to the left or right branch road side, Since the take-up reel is fixed and suspended toward the branch runway, the power supply cable may come off the side edge of the cable take-up reel when the doffing truck travels left and right on the transfer route. , The power supply cable cannot be smoothly sent out, and the power supply cable is twisted during winding, and the doffing truck travels in the left-right direction in the width direction of the cable winding reel. However, when pulling out the cable take-up reel due to the running force of the doffing dolly, it may not be possible to pull out the power supply cable at times, and also the power supply cable itself may be subjected to large force, which may cause the power supply cable to break. This is also a cause, and therefore the power supply cable must be made thicker, and the power supply device must be made larger.

Therefore, it is an object of the present invention to provide a power feeding device, particularly a power feeding device capable of smoothly feeding a power feeding cable to a doffing cart of a false twisting machine and winding it. .

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a cable winding reel that winds a feeding cable for a doffing trolley so that the cable winding reel can run along a rail, and a swing arm in the width direction of the cable winding reel. An oscillating reel supported oscillatably by means of is provided in the cable pull-out direction of the cable take-up reel, and a fixed guide reel is provided in the feeding cable path between the cable take-up reel and the oscillating reel. The feeder cable can be smoothly sent to the doffing trolley of the twisting machine and can be wound up.

[0010]

[Action]

 Since the present invention is configured as described above, during the doffing operation of the false twisting machine, the doffing trolley travels on the main traveling path and travels to the connection point of the transfer path connecting to the branch traveling path. At this time, the cable take-up reel along with the doffing truck also runs along the rail and stops at the connection point of the transfer path. When the doffing dolly travels from this connection point to the transfer path in either direction of the two branch runways, the feeding cable connected from the cable winding reel to the doffing dolly via the swing reel is Since the cable reel moves along with the doffing carriage in the width direction of the cable take-up reel around the cable take-up reel, the swing reel moves in the moving direction of either the left or right doffing cart from the swing center. Rocks with. At this time, since the power feeding cable from the cable take-up reel to the swing reel is guided by the fixed guide reel in the meantime, even if the position of pulling out the power feeding cable of the cable take-up reel changes in the width direction of the reel, The fluctuation of the tension of the power supply cable that is sent out is eliminated. Further, even if the swing reel swings, the influence of the swing of the power feeding cable is blocked by the fixed guide rail, and the cable take-up reel is not affected.

The doffing carriage that travels on the transfer path travels on the branch travel path, performs the doffing operation of the false twisting device of the row, and returns to the transfer path again after the work is completed. When the doffing trolley reciprocates on the branch road, the cable take-up reel takes out and winds the cable. The doffing truck that has returned to the transfer route travels to the adjacent branch traveling route and performs the same doffing work, and the cable take-up reel also performs the same operation. The doffing trolley, which has finished the doffing work after traveling along the two-row branch runway connected to the transfer route, returns to the main runway, runs along the main runway with the cable winding reel, and then moves to the next row. The doffing work of the false twisting device is performed by the same operation as above, and the doffing work of the false twisting devices of all rows is performed.

[0012]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The draw false twisting machine is configured as shown in FIG. That is, the yarn 52 fed from the yarn supply package 51 in the creel stand 50 is held by the first feed roller 53 and the second feed roller 54 at a stretchable yarn tension. A false twist member 55 such as a nip twister is provided on the downstream side between these two sets of feed rollers 53 and 54, and the yarn 52 upstream of the false twist member 55 is in a twisted state.

A heat fixing primary heater 56 is provided on the upstream side between these two sets of feed rollers 53 and 54, and heats the false twisted yarn 52 to the drawing temperature. Further, a third feed roller 57 is provided downstream of the second feed roller 54, and a secondary heater 58 is provided between these two sets of feed rollers 54, 57 to perform heat treatment. The yarn 52 after the heat treatment is wound into the package 60 by the take-up winder 59.

In the draw false twisting machine, since the primary heater 56 is particularly tall, the primary heater 56 is separated from the main body 61 after the false twisting member 55 so as to be opposed to each other, and a passage 62 is provided between the primary heater 56 and the main body 61. It facilitates operations, doffing work, and maintenance work. At the time of doffing work, a doffing cart 63 is movably arranged along the front surface of the false twisting machine body 61 in the passage 62, and a laterally movable peg stand 64 is installed on the passage 62 side of the primary heater 56. ing.

The peg stand 64 has three pegs 65 protruding toward the passage 62. The doffing trolley 63 transfers the package 60 formed on the front of the false twisting machine main body 61 to the peg 65, holds the package 60 on the bobbin portion, picks it up from the take-up winder, and picks up the package 60 at 90 degrees. It has the function of changing direction and moving it to the opposite position of the peg 65, pushing the package toward the peg 65, and at the same time attaching the empty paper tube to the take-up winder and threading. The peg stand 64 having the package inserted therein is moved laterally, and the operator collects the package at a predetermined position.

A large number of such draw false twisting machines are arranged adjacent to each other to form one row of false twisting machines, and in order to simplify the facility equipment in the factory and effectively use the space, the above described one row of false twisting machines is used. On the back side of the machine, the same one-row false twisting device is arranged back to back. After that, multiple false twisting devices are arranged in the same manner. In the false twisting plant, as shown in Fig. 4, there are multiple false twisting devices 1. Are arranged in parallel.

The branch runway 2 on which the doffing dolly in front of the false twisting device of each row travels is connected by a common main runway 3 and a transfer path 4 arranged at the end of the false twisting device of each row. The transfer path 4 connects the branch running paths of the two rows of false twisting devices arranged back to back with each other. As a result, the doffing cart 5 traveling on the main traveling path 3 is connected to the branch traveling paths 2-1 and 2-2 and the transfer path 4 connecting the main traveling path 3, for example, the first transfer station 6 -1 to stop and then travel on the first transfer path 4-1 side of the transfer path 4 which is connected to the branch travel path 2-1 and travels on the branch travel path 2-1 to temporarily move this row. Perform the doffing work of the twisting machine. After the doffing work of this row is completed, it returns to the first transfer path 4-1 again and returns to the first transfer station 6-1. After that, when the doffing work of the false twisting device 1-2 is necessary, the false twisting device 1-2 travels along the second transfer path 4-2 and then along the branch travel path 2-2. As a result, the doffing work of the false twisting device 1-2 in this row is performed, and after the work is completed, it returns to the second transfer path 4-2 and returns to the first transfer station 6-1. After that, the doffing trolley travels on the main running path 3, stops at the transfer station of the transfer path connected to the branch running path of the false twisting device of the row requiring doffing work, and repeats the same operation as above. .

On the other hand, the doffing trolley requires a power source for the traveling motor, the doffing motor, the package and the paper tube insertion / removal power source actuator, etc. As shown in FIG. 2, a trolley duct 11 and an angle rail 12 are laid on the ceiling of the main road 4. A cable winding device 13 that is guided by the angle rail 12 and receives electric power and a control signal from the trolley duct 11 and is self-propelled is movably provided. Further, the cable winding device 13 is provided with a winding reel 15, and a power feeding cable 14 that is unwound or rewound from the winding reel 15 by a spring 16 such as a mainspring is connected to the doffing carriage 6. That is, the doffing cart 6 is supplied with electric power and control signals via the trolley duct 11 and the power supply cable 14, and the cable winding device 13 is supplied with electric power and control signals via the trolley duct 11. It has become.

As shown in FIGS. 1 and 2, the cable take-up reel 13 is rotatably supported by a bracket 21 at a lower portion of a main body 20 which is suspended by an angle rail 12 and travels. The pulley 22 provided on the side of the reel 15 is driven by the motor 23 provided inside the main body 20 via the belt 24, whereby the take-up reel 15 is rotationally driven, and the feeding cable 14 is taken up on the take-up reel. It is possible. A clutch is provided between the motor 23 and a belt driving pulley (not shown), and the cable take-up reel 13 can freely rotate when the clutch is removed.

At the middle position of the bracket 21 that supports both sides of the take-up reel 15, a rotation support member 25 is provided at the bottom of the main body 20, and inside the rotation support member 25, it is rotatable by a flange 26. A swing arm 27 to be supported is provided, and a swing reel 30 is rotatably supported on a bracket 28 at the tip of the swing arm 27.

A fixed guide reel 41 supported by a bracket 40 fixed to the bottom surface of the main body 20 is provided on the opposite side of the swing reel 30 provided in the doffing trolley direction around the cable take-up reel 13. The power feeding cable 14 from the cable take-up reel 13 is guided rearward to pass through the fixed guide reel 41, and then forward to be connected to the doffing trolley through the swing reel 30.

In the above-mentioned configuration, for example, when a full winding signal is output from the false twisting device 1-1, the doffing trolley 5 waiting at the home position 9 of the main traveling path 4 travels on the main traveling path 4. 1 Stop at transfer station 6-1. At this time, since the main body 20 travels along the rail 12 with the doffing carriage, the cable winding device 13 swings to the upper part of the first transfer station 6-1 and stops while holding the cable.

Next, the doffing carriage 5 is transferred to the transfer path 4 side and travels on the first transfer path 4-1 connected to the branch travel path 2-1 of the false twisting device 1-1. At this time, while the cable winding device 13 is stopped, the doffing carriage moves in the width direction of the reel, so that the feeding cable 14 after the swing reel 30 is pulled in that direction, so that the swing reel 30 also. The oscillating arm 27 is pulled in that direction, and the oscillating arm 27 oscillates around the flange 26 portion in the rotation supporting member 25 by the force, and oscillates the oscillating reel 30 in the moving direction of the doffing dolly. As a result, the power supply cable swings around the fixed guide reel 41, and does not affect the cable winding reel 13 by the swing of the swing reel 30. Since the length between the fixed guide reel 41 and the swing reel 30 which is the swing radius of the power feeding cable is longer than the length of the swing arm 27 which is the swing radius of the swing reel 30, the swing arm 2 The swing angle of the power supply cable 14 becomes small regardless of the large swing of 7, and there is no fear that the power supply cable 14 will come off from the swing reel 30 or the fixed guide reel 41.

When the doffing carriage 5 travels along the transfer path 4 and the branch travel path 2 for doffing work, the clutch provided at the output shaft end of the motor 23 is disengaged and the cable take-up reel is set in a free state. Every time, the feeding cable 14 is paid out from the winding reel 15 by the force of pulling the feeding cable by the traveling force of the doffing dolly. At this time, the position at which the power supply cable is fed from the take-up reel moves in the width direction of the reel, which tends to cause tension fluctuations in the fed power supply cable, but the power feed cable is passed through the fixed guide reel 41. As a result, this tension fluctuation can be absorbed.

The doffing carriage 5 travels along the first transfer path 4-1 and then along the branch travel path 2-1 to perform the doffing work of the false twisting device of this row. When the doffing work of this row is completed, the doffing trolley 5 starts traveling in the opposite direction, but the motor 23 is driven by the signal at that time and the clutch is also connected to the doffing trolley 5 via the belt 24 and the pulley 22. The take-up reel 15 winds the cable 14 with a predetermined force and absorbs the slack of the power feeding cable to the doffing dolly 5.

When the doffing carriage 5 travels the first transfer path 4-1 again, the swing reel 30 is moved by the swinging arm 27 along with the movement of the doffing carriage. When the doffing dolly returns to the first transfer station 6-1, and further the doffing work of the false twisting device 1-2 in the next row is required, the doffing trolley travels along the second transfer path 4-2. Also at this time, similarly to the above, the swing reel 30 swings along the traveling direction of the doffing cart 5, and the swing arm 27 also swings in that direction, that is, in the clockwise direction in FIG. The doffing trolley runs from the second transfer path 4-2 to the branch traveling path 2-2 while the power supply cable is being fed from the cable winding reel 13, and performs the doffing work of the false twisting device of this row.

When the doffing of the false twisting device 1-2 in this row is also completed, the doffing carriage 5 returns to the first station 6-1 again, and then doffing is required by a command from the control device. Stop at the transfer station connected to the branch runway of the false twisting device of the row. During this run of the doffing trolley, the cable take-up reel also runs in parallel and stops with the doffing trolley at the specified transfer station. After that, the doffing dolly is run, the cable take-up reel is wound, and freely rotated by the same operation as described above.

In the above embodiment, the cable take-up reel is stopped on the transfer station even while the doffing vehicle is traveling on the branch traveling path. You may make it run to the rail position on the extension of the branch road and stop it. Further, as the switch for detecting the swing of the swing lever 27, various kinds of switches other than the above-mentioned embodiment can be used.

[0029]

[Effect of device]

 Since the present invention is constructed and operates as described above, the swing reel reliably guides the power feeding cable even when the doffing truck travels in various directions, and is prevented from coming off the cable winding reel. In addition, even if the tension of the power feeding cable is changed due to the feeding position of the power feeding cable fed from the cable winding reel moving in the width direction of the reel, the power feeding cable is guided by the fixed guide reel. Since the tension of the power supply cable is not changed after the fixed guide reel, the power supply cable can be sent out stably and the winding can be performed in a stable manner.
