As shown in FIGS. 9 and 11, the fixing device 42 has an operating lever 63, a connecting member 64, and a connecting mechanism 65 for connecting the operating lever 63 and the connecting member 64. As shown in FIG. 9, the operation lever 63 is rotatable between a posture tilted to the back side (solid line) and a posture tilted to the front side (dashed-dotted line). The connecting member 64 is provided with an air connecting portion 68 and two guide rollers 69 arranged so as to sandwich the air connecting portion 68. The connecting mechanism 65 has three connecting shafts 66 that connect the connecting member 64 and the operating lever 63, and a frame body 67 that is fixed to the main body frame 41 and through which the three connecting shafts 66 are inserted.

On the other hand, the connecting portion 31 on the winding table 3 side includes a fixing member 37 having two guide surfaces 37a arranged at intervals in the front-rear direction. Further, in the portion of the fixing member 37 between the two guide surfaces 37a, an air supply unit 38 (power supply unit of the present invention) connected to the air supply source (not shown) of the false twisting machine 1 is provided. It is provided.

When the operation lever 63 is tilted toward the front side, as shown in FIG. 11A, the connecting member 64 of the package unloading device 40 and the fixing member 37 on the take-up table 3 side are separated from each other, and the package unloading is performed. The device 40 is not fixed to the connection portion 31.

On the other hand, when the operating lever 63 is tilted to the back side, as shown in FIG. 11B, the connecting member 64 connected to the operating lever 63 by the three connecting shafts 66 is pushed into the back. At this time, the two guide rollers 69 of the connecting member 64 move along the two front and rear guide surfaces 37a of the fixing member 37 on the take-up table 3 side. That is, the fixing member 37 is inserted between the two guide rollers 69 of the connecting member 64. As a result, the main body frame 41 is fixed so as not to be movable in the front-rear direction. At the same time, the air connection portion 68 of the package unloading device 40 is connected to the air supply portion 38 on the take-up table 3 side. As a result, air for operating the air hoist 44 and the air cylinder 59 can be supplied from the air supply source on the take-up table 3 side to the package unloading device 40.

The package unloading device 40 of the present embodiment can operate the air hoist 44 and the air cylinder 59 by the air from the air supply source installed on the take-up table 3 side. That is, since it does not have a motor driven by electricity, it is not necessary for the package unloading device 40 itself to be equipped with a power source, and it is not necessary to supply electric power from the outside.

The cover 45 covers the package receiver 43 at the collection position to prevent an operator from accidentally putting a hand or the like into the package receiver 43 when the package receiver 43 is raised. As shown in FIGS. 5 to 8, the cover 45 has a frame body 70 and a net 71 stretched over the frame body 70. In the present embodiment, the cover 45 is a shutter provided on the front side portion of the main body frame 41, and has a lower closed position (FIGS. 5, 7, 8) and an upper open position (FIG. 6). Move up and down over.

The cover 45 of the present embodiment is configured to be manually moved up and down. Specifically, a handle 72 is attached to the lower part of the frame 70 of the cover 45, and an operator grips the handle 72 to raise or lower the cover 45. A configuration in which the cover 45 is driven up and down by an air cylinder or the like may be adopted.

When the cover 45 is in the lower closed position, as shown in FIG. 7, the package receiver 43 in the collection position is covered by the cover 45 from the front side. Even when the package receiver 43 is covered with the cover 45, it is possible to check the state of the package receiver 43 (whether or not the take-up package P is mounted, etc.) through the net 71 (see FIG. 5). There is. On the other hand, when the cover 45 is in the upper open position, as shown in FIG. 6, the package receiver 43 in the collection position is opened toward the front side, and the take-up package P mounted on the package receiver 43 can be taken out. It will be possible.

As shown in FIG. 6, a switch 73 that comes into contact with the lower end of the cover 45 when the cover 45 is in the closed position is provided in the lower portion of the main body frame 41. The switch 73 switches between supplying and shutting off the air supplied from the air supply unit 38 on the take-up table 3 side via the air connection unit 68 to the air hoist 44.

When the cover 45 is in the closed position, the switch 73 is turned on and air can be supplied to the air hoist 44. That is, the air hoist 44 allows the package receiver 43 to move up and down. On the other hand, when the cover 45 is in the open position, the switch 73 is turned off and the air supply to the air hoist 44 is cut off. Therefore, the air hoist 44 is prohibited from moving up and down the package receiver 43.

The operation box 46 is provided on the rear side surface of the main body frame 41. The operation box 46 is provided with a lever 74 for operating the air cylinder 59 of the package receiver 43. Further, a pendant switch 47 (operation unit of the present invention) for operating the air hoist 44 is detachably held under the operation box 46 of the main body frame 41. The operator can operate the air hoist 44 by removing the pendant switch 47 from the main body frame 41 and observing the state of the package unloading device 40 from a place away from the main body frame 41.

Next, a series of operations for collecting the package from the take-up table 3 by using the package unloading device 40 will be described.

When unwinding the winding package P from the 4th and 5th stage stockers 27 of a winding table 3 using the package unloading device 40, the operator first grasps the handles 51 to 54 to unload the package. The device 40 is moved back and forth to move it to the position of the target take-up table 3. Further, the package unloading device 40 is stopped while observing the tip position of the mark member 75 (see FIG. 11), and the position of the package unloading device 40 in the front-rear direction is tentatively determined. Next, as shown in FIG. 9, the operating lever 63 of the fixing device 42 is tilted from the front to the back to fix the position in the front-rear direction of the package unloading device 40. At this time, as shown in FIG. 11B, the air supply unit 38 on the take-up table 3 side and the air connection unit 68 of the package unloading device 40 are connected.

Next, as shown in FIG. 7, the cover 45 in the open position is lowered to the closed position. As a result, the package receiver 43 at the lower collection position is covered from the front side by the cover 45. Further, at this time, the lower end of the cover 45 comes into contact with the switch 73, the switch is turned on, and the package receiving 43 can be raised and lowered by the air hoist 44.

Next, the operator operates the pendant switch 47 to operate the air hoist 44, and as shown in FIG. 8, raises the package receiving 43 from the collecting position to the receiving position. At this time, the upper package mounting portion 58 moves near the fifth-stage (top) stocker 27, and the lower package mounting portion 58 moves near the fourth-stage stocker 27. In this state, when the operator operates the lever 74 of the operation box 46 to operate the air cylinder 59, the regulation member 28 (see FIG. 4) of each stocker 27 is operated, and the winding package P of each stocker 27 is operated. , Rolls out to the corresponding package mounting section 58. As a result, the package receiver 43 receives a total of eight winding packages P from the stockers 27 in the fourth and fifth stages.

When the take-up package P moves to each package mounting portion 58, the take-up package P is detected by the sensor and the indicator lamp 61 lights up. After confirming that all the winding packages P to be collected have been received by the indicator lamp 61, the operator operates the pendant switch 47 to lower the package receiving 43 from the receiving position to the collecting position.

When the package receiver 43 is moved to the collection position, the operator raises the cover 45 to the open position to open the package receiver 43, and sequentially takes out eight winding packages P from the package receiver 43 and collects them. It is not necessary to immediately take out the winding package P from the package receiving 43 in front of the winding table 3 on which the work has been performed. That is, the package unloading device 40 is moved in the front-rear direction with the take-up package P mounted on the package receiver 43, and the take-up package P is moved from the package receiver 43 at a place away from the take-up stand 3 where the package unloading work is performed. May be taken out.

The package unloading device 40 of the present embodiment is used to collect the fourth-stage and fifth-stage winding packages P. Since the winding packages P in the first to third stages are lower than those in the fourth and fifth stages, the operator may directly collect them from the stocker 27. At that time, it is desirable to move the package unloading device 40 to a position away from the winding table 3 to be collected from the package so as not to interfere with the collection work.

The package unloading device 40 of the present embodiment can easily unload the take-up package P at a high position by moving the package receiving 43 between the upper receiving position and the lower collecting position. Further, since the main body frame 41 can be moved in the arrangement direction of the take-up table 3, one common package unloading device 40 can unload a plurality of take-up packages P of the take-up table 3.

Further, in the present embodiment, the upper end portion of the main body frame 41 is connected to the winding table 3 by the connecting portion 55. Therefore, it is possible to prevent the main body frame 41 from tipping over during the work of lowering the take-up package P. Further, the connecting portion 55 is movably connected to an upper rail 33 extending over the upper part of the plurality of winding stands 3. Therefore, even when the main body frame 41 is moved in the front-rear direction, the main body frame 41 is prevented from falling.

In particular, in the present embodiment, the main body frame 41 is tall (for example, 3 m or more) in order to unload the take-up package P from the stocker 27 at a high position. On the other hand, as shown in FIG. 1, it is difficult to increase the space 77 between the winding table 3 and the creel stand 4 from the viewpoint of suppressing the size of the false twisting machine 1 in the left-right direction. Therefore, even in the limited space 77, the dimensions of the main body frame 41 in the depth direction (left-right direction of the false twisting machine 1) are kept small (for example, 0) in order to secure a space for package collection work. 0.8m or less).

That is, the main body frame 41 is a structure having a small depth and a high height. Therefore, when a plurality of heavy take-up packages P are placed on the package receiver 43 at the upper receiving position, the balance becomes poor, and the package unloading device 40 may tilt in the left-right direction. From this, the configuration of the present embodiment in which the upper end portion of the main body frame 41 is connected to the take-up table 3 is very useful for surely preventing the main body frame 41 from collapsing.

The body frame 41 is provided with a cover 45 that moves between the closed position and the open position. Therefore, when the package receiver 43 in the collection position is moved to the upper receiving position, the cover 45 is closed so that the operator accidentally puts a hand or the like near the package receiver 43 immediately before moving upward. Can be prevented from being plugged in. On the other hand, when the take-up package P is received and returned to the collection position, the cover 45 can be opened and the take-up package P can be taken out from the package receiver 43.

Further, when the cover 45 is in the closed position, the switch is turned on and air can be supplied to the air hoist 44. That is, only when the cover 45 is in the closed position, the air hoist 44 is allowed to move the package receiver 43 up and down. That is, when the cover 45 is in the open position and the package receiving 43 in the collecting position is not covered with the cover 45, the package receiving 43 does not move to the receiving position. Therefore, it is possible to reliably prevent the operator from accidentally inserting a hand or the like near the package receiver 43 immediately before moving upward.

The package unloading device 40 has a fixing device 42 that immovably fixes the main body frame 41 in the front-rear direction. By fixing the main body frame 41 by the fixing device 42, it is possible to prevent the main body frame 41 from moving in the front-rear direction during the work of lowering the take-up package P.

Further, when the main body frame 41 is fixed by the fixing device 42, the air connection portion 68 of the package unloading device 40 is connected to the air supply portion 38 on the take-up table 3 side. Therefore, it is not necessary to equip the package unloading device 40 with an air supply source for driving the air hoist 44 or the like. Further, since the main body frame 41 is fixed and connected to the air supply unit 38 at the same time, no special operation for this connection is required, and the work process is simplified.

Further, according to the package unloading device 40 of the present embodiment, the package can be unloaded from a stocker located at a position of 2.3 m or more from the floor surface, which is difficult for workers to reach.

Further, in the package unloading device 40 of the present embodiment, the operator operates the lever 74 of the operation box 46, the pendant switch 47, and the like to operate the air cylinder 59 of the package receiver 43 and the air hoist 44 for raising and lowering. Then, the take-up package P is unloaded from the stocker 27. That is, the package unloading device 40 is a so-called semi-automatic device that operates based on the operation of the operator.

In this configuration, the operator can unload the take-up package P from the stocker 27 at a high place by operating the pendant switch 47 or the like, so that the work load can be reduced. On the other hand, since the operator raises and lowers the package receiver 43 after checking the surrounding conditions, it is easier to deal with sudden troubles, compared to a device that collects the take-up package P fully automatically. It is highly safe. Further, it suffices to have only the minimum necessary drive unit for lowering the take-up package P such as the air hoist 44, which is advantageous in terms of cost and energy saving as compared with the fully automatic device.

Next, a modified embodiment in which various modifications are made to the embodiment will be described. However, those having the same configuration as that of the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted as appropriate.

However, in particular, the upper rail 33 is not essential from the viewpoint of preventing the device from falling over during the package unloading work. That is, when the package unloading device is moved to the front of the take-up table 3 to be worked on, the package unloading device may be connected to the upper end portion of the take-up table 3 by the connecting portion. That is, each time the package unloading device is moved / stopped, it may be connected to and disconnected from the take-up table 3.

2] The lower rail 30 extending over the lower part of the plurality of take-up stands 3 is also not essential. For example, the package unloading device may have a plurality of tires and may be configured to be able to freely travel on the floor by the plurality of tires. In this case, one package unloading device can be moved between the plurality of false twisting machines 1 and used in common for the plurality of false twisting machines 1.

3] The cover is not limited to the configuration of the above embodiment. For example, the cover does not have to be a shutter type that moves in the vertical direction, and may be a door type that swings and opens toward the front side of the operator.

4] The package receiving device of the package unloading device can be changed as follows, for example.

The package receiver 43 of the above embodiment receives the take-up package P from the 4th and 5th (top) stockers 27 of the take-up table, but the take-up package P is received only from the top stocker 27. May be received.

Further, the package receiver 43 of the above embodiment receives four winding packages P arranged in front and back at one time for each stage, but the number of winding packages P received by the package receiver at one time can be changed as appropriate. Is. For example, even when four front and rear stockers 27 are lined up on each stage of the take-up stand 3, the package receiver may receive the take-up package P only from the two stockers 27. That is, the four winding packages P of each stage may be received in two batches.

Further, the package receiving 43 of the package unloading device 40 of the above embodiment has a configuration in which the winding package P can be received from the upper and lower two-stage stockers 27 of the winding table 3, respectively, but from the three-stage or higher stockers 27. It may be configured so that the take-up package P can be received at the same time. That is, the package receiver may have three or more package mounting portions 58 arranged one above the other. Alternatively, contrary to the above, the package receiver may receive the take-up package P only from the one-stage stocker 27.

5] The package unloading device 40 of the above embodiment is an air-driven device that operates by receiving an air supply from an air supply source on the take-up table 3 side. On the other hand, the package unloading device is an electric type device provided with a motor (elevating / lowering drive unit of the present invention) for raising / lowering the package receiver and receiving electric power from the power supply on the winding table 3 side to drive the motor. There may be. Further, in the case of the electric type, the package unloading device may be provided with a dedicated power supply.

6] The fixing device for fixing the position of the package unloading device does not need to be provided in the package unloading device, and may be provided on the take-up table 3 or on the floor.

7] It is not essential that the package unloading device is connected to the power supply unit (air supply unit 38 in the above embodiment) on the take-up table side in conjunction with the operation of the fixing device 42, and the operation of the fixing device 42 is not essential. Separately, connection work with the power supply unit may be performed.

8] The package unloading device 40 of the embodiment receives the take-up package P from the take-up stand 3 to which the take-up device 22 is attached, and unloads the take-up package P downward. On the other hand, the take-up package P formed by the take-up device may be placed on a stand (package stand) different from the take-up stand. In this case, the package unloading device receives the take-up package P from the package stand instead of the take-up stand to which the take-up device is attached.

9] In a general false twisting machine 1, many take-up stands 3 are lined up in the front-rear direction. Therefore, if there is only one package unloading device 1, it is conceivable that a waiting time for package unloading work will occur. Be done. Therefore, a plurality of package unloading devices may be provided for one false twisting machine 1.

In the above description, an example in which the present invention is applied to a false twisting machine is shown, but the present invention is applied to a textile machine other than the false twisting machine, which winds a yarn on a bobbin to form a take-up package. Can also be applied.
