When releasing the wrapping package from any package, the main body frame is moved to the position of the target package band first. Then, the lifting drive unit lifts the package receiver to the receiving position, and moves the wound package stored in the stocker of the package stand to the package receiver. In this state, the package receiver is lowered to the return position by the lifting drive section.

In the present invention, by moving the package receiver over the upper receiving position and the lower receiving position, the winding package at a higher position can be easily lowered. In addition, since the main frame can be moved in the arrangement direction of the package base, a plurality of package base wrapping packages can be lowered by a common package unloading device.

The package unloading apparatus of the second invention is the package unloading apparatus of the first invention, wherein each package stand comprises a plurality of stages of the stockers arranged in the vertical direction, and the receiving position of the package receiver is a position And is a position for receiving the wound package from the stocker.

In the package unloading apparatus of the present invention, in the structure in which a plurality of stockers are arranged in the up-and-down direction, the take-up package is lowered from the uppermost stocker at the highest position. Further, with respect to the stocker at the lower end, the winding package may be put down using the apparatus of the present invention as in the uppermost stage, but it may be lowered by the operator because it is lower than the uppermost stocker.

The package unloading apparatus of the third invention is characterized in that, in the second invention, each package stand comprises three or more stages of the stocker.

Next, an embodiment of the present invention will be described. Fig. 1 is a view of the false twisting machine 1 of the present embodiment viewed from the longitudinal direction of the main base 2 (the arrangement direction of the winding cradle). 2 is a perspective view of the winding table 3. Fig. 1, the longitudinal direction of the main base 2, which is the vertical direction of the plane of Fig. 1, is referred to as " forward and backward direction of the false twister, " Direction ", respectively.

(Overview of the false twister)

As shown in Fig. 1, the twisting machine 1 according to the present embodiment (a textile machine according to the present invention) has a main base 2 extending forward and backward in the middle in the left and right direction, A plurality of winding bobbins 3 (package base of the present invention) arranged in the front-rear direction and a plurality of crush stands 4 arranged in the front-rear direction on the outer side of the winding bobbins 3.

The feed roller 10, the first heating device 11, the anti-kink guide 12, the cooling device 13, the misfire device 14, the feed roller (not shown) The second heating device 16 and the feed roller 17 are arranged side by side from the top of the winding table 3 to the bottom of the main table 2 and the winding table 3.

Further, the entire twist processing machine 1 is divided into a plurality of sections B (also referred to as spans) arranged in the longitudinal direction. A twisted yarn Y is wound around twenty yarns Y in the one section B of the false twisting machine 1, . Fig. 2 shows a configuration in which one wind-up table 3 is provided for one section B. Fig. Twenty winding devices 22 for winding twenty yarns Y are attached to one winding table 3, respectively. In addition, one creel stand 4 holds twenty yarn feeding packages S that supply twenty yarns Y to one twisted portion 5. [

(Flutter)

The twisted portion 5 includes a feed roller 10, a first heating device 11, a cooling device 13, a twisting device 14, a feed roller 15, and a feed roller 15 in this order from the upstream side in the running direction of the yarn Y. [ A second heating device 16, and a feed roller 17, as shown in Fig.

The feed roller 10 is provided above the winding table 3 to feed the yarn Y that has been unwound from the yarn feeding package S toward the first heating device 11. [ The first heating device 11 is disposed on the center side with respect to the feed roller 10 to heat the yarn Y fed by the feed roller 10. An anti-twist guide 12 is provided on the upstream side of the first heating device 11. The anti-twist guide 12 is for preventing the twist from being transmitted to the upstream side of the first heating device 11 when twist is given to the yarn Y by the later-described twist device 14. [ The cooling device 13 is disposed on the center side with respect to the first heating device 11 to cool the yarn Y heated by the first heating device 11. [

The flammable device 14 is provided on the upper portion of the main base 2 to impart a twist to the yarn Y between the anti-twist guide 12 and the flammable device 14. [ The yarn Y is heated by the first heating device 11 and is twisted by the twisted device 14 and then thermally fixed by being cooled by the cooling device 13. [ The thermally fixed yarn Y is untwisted between the twisting device 14 and the feed roller 15. [ As a result, the twist of the yarn Y is released, but the waveform of the yarn Y remains in the filament of the yarn Y because the first heating device 11 performs the heat fixing. This series of thread machining is generally referred to as " twist machining ".

The feed roller 15 is provided in the main base 2 and conveys the yarn Y delivered from the false device 14 toward the second heating device 16. [ In addition, the actual feed speed of the feed roller 15 is faster than the actual feed speed of the feed roller 10. Therefore, the yarn Y is stretched between the feed roller 10 and the feed roller 15, and the yarn Y is subjected to the twisting process. The second heating device 16 is installed at a position below the feed roller 15 of the main base 2 to heat the yarn Y fed by the feed roller 15.

The feed roller 17 is disposed near the lower portion of the winding table 3 and sends the yarn Y subjected to the heat treatment by the second heating device 16 to the winding device 22 of the winding table 3. The actual feed speed by the feed roller 17 is slower than the actual feed speed by the feed roller 15. [ Therefore, the yarn Y is heat-treated by the second heating device 16 in a state where the yarn Y is loosened between the feed roller 15 and the feed roller 17. [

A workbench or a workbench, not shown, is installed in the upper space of the yarn path between the second heating device 16 and the feed roller 17. The worker climbs to a workbench or a work truck to perform a threading operation to the combustible device 14 or the like constituting the false-twist portion 5.

When the regulating member 28 is in the attitude shown in Fig. 4, the first claw portion 28a protrudes while the second claw portion 28b is retracted. At this time, the winding package P (P1) located on the outer side in the stocker 27 is restricted from being pushed out of the stocker 27 by the first claw portion 28a. When the operating portion 28c is pushed out and the regulating member 28 swings in the counterclockwise direction, the first claw portion 28a is retracted and the outer winding package P (P1) is rolled out of the stocker 27. At this time, at the same time, the second claw portion 28b is protruded to restrict the winding package P (P2) located on the inner side from rolling together. When the operation of the air cylinder 59 is completed and the regulating member 28 returns to the posture shown in Fig. 4, the second claw portion 28b is retracted to collapse the inner package P (P2) And is stopped by the first claw portion 28a.

(Package unloading device)

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 wind-up table 3 side. That is, the fixing member 37 is pushed between the two guide rollers 69 of the connecting member 64. Thereby, the main body frame 41 is fixed so as not to move 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 side of the winding table 3. So that air for operating the air hoist 44 or the air cylinder 59 can be supplied from the air supply source on the winding table 3 side to the package unloading apparatus 40. [

The package unloading apparatus 40 of the present embodiment can operate the air hoist 44 and the air cylinder 59 by air from an air supply source provided on the winding table 3 side. That is, the package unloading apparatus 40 itself does not need to be provided with a power source in that it does not have a motor driven by electric power, and power supply from the outside is also unnecessary.

The cover 45 covers the package receiver 43 at the recovery position to prevent the operator from accidentally putting his or her hand into the package receiver 43 when the package receiver 43 is lifted. As shown in Figs. 5 to 8, the cover 45 has a frame body 70 and a net 71 engaged with the frame body 70. Fig. In the present embodiment, the cover 45 is a shutter provided at a portion on the front side of the main body frame 41. The cover 45 is a shutter provided at a lower side close position (FIGS. 5, 7 and 8) and an upper side open position .

The cover 45 of this embodiment is a structure that is manually operated up and down. Specifically, a handle 72 is attached to the lower portion of the frame 70 of the cover 45, and the operator holds the handle 72 and moves the cover 45 up and down. The cover 45 may be vertically driven by an air cylinder or the like.

When the cover 45 is in the lower closed position, as shown in Fig. 7, the package receiver 43 at the return position is covered by the cover 45 from the front side. Even if the package receiver 43 is covered by the cover 45, the state of the package receiver 43 (whether or not the package package P is loaded, etc.) through the net 71 It is possible to confirm it. On the other hand, when the cover 45 is in the upper open position, as shown in Fig. 6, the package receiver 43 at the retrieved position is opened to the front side and the package package P loaded on the package receiver 43 It becomes possible to take out.

As shown in Fig. 6, a switch 73 is provided in the lower portion of the main body frame 41 to contact the lower end of the cover 45 when the cover 45 is in the closed position. The switch 73 switches supply and interruption of the air supplied from the air supply unit 38 on the wind-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 the air supply to the air hoist 44 is enabled. That is, the lifting and lowering of the package receiver 43 by the air hoist 44 is allowed. On the other hand, when the cover 45 is in the open position, the switch 73 is turned off and air supply to the air hoist 44 is interrupted. Therefore, the lifting and lowering of the package receiver 43 by the air hoist 44 is prohibited.

The operation box 46 is provided on the rear side 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. A pendant switch 47 (operating portion of the present invention) for operating the air hoist 44 is detachably held below the operation box 46 of the main body frame 41. The operator can operate the air hoist 44 while separating the pendant switch 47 from the main body frame 41 and viewing the state of the package unloading device 40 from a position away from the main body frame 41. [

Next, a series of operations for collecting the package from the winding table 3 using the package unloading apparatus 40 will be described.

When the package unloading apparatus 40 is used to lower the package P from the fourth and fifth storages 27 of a certain winding cradle 3, the operator first grasps the handles 51 to 54, The apparatus 40 is moved forward and backward to the position of the target winding table 3. The package unloading device 40 is stopped while looking at the tip position of the display member 75 (see Fig. 11) to temporarily determine the position of the package unloading device 40 in the longitudinal direction. Then, as shown in Fig. 9, the operation lever 63 of the fixing device 42 is conducted from the front side to the inside side to fix the position of the package unloading device 40 in the longitudinal direction. At this time, the air supply portion 38 on the winding table 3 side and the air connection portion 68 on the package unloading device 40 are connected as shown in Fig. 11 (b).

Then, as shown in Fig. 7, the cover 45 in the open position is lowered to the closed position. Thus, the package receiver 43 at the bottom return position is covered by the cover 45 from the front side. At this time, the lower end of the cover 45 contacts the switch 73 and the switch is turned on, so that the package receiver 43 can be lifted and lowered by the air hoist 44.

Then, the operator operates the pendant switch 47 to operate the air hoist 44 to raise the package receiver 43 from the return position to the receiving position, as shown in Fig. At this time, the upper package placing portion 58 moves to the vicinity of the fifth stage (uppermost stage) stocker 27, and the lower package placing portion 58 moves to the vicinity of the fourth stage stoker 27. In this state, when the operator operates the lever 74 of the operation box 46 to actuate the air cylinder 59, the regulating member 28 (see Fig. 4) of each stocker 27 is operated and the respective stockers 27 Is wound on the corresponding package placing portion 58. Thus, the package receiver 43 receives eight wrapping packages P in total from the fourth and fifth-tier stockers 27.

When the package P is moved to each package placing portion 58, the package P is detected by the sensor and the display lamp 61 is turned on. When confirming that all the receipt of the package package P to be collected is completed by the display lamp 61, the operator operates the pendant switch 47 to lower the package receiver 43 from the receiving position to the collecting position.

When the package receiver 43 is moved to the return position, the operator raises the cover 45 to the open position to open the package receiver 43 and sequentially withdraws the eight packages P from the package receiver 43 . It is not necessary to take out the package P from the package receiver 43 in front of the winding table 3 on which the work has been performed. That is, the package unloading device 40 is moved back and forth in a state where the package P is loaded on the package receiver 43, so that the package receiver 43 is moved away from the winding table 3, The take-up package P may be taken out.

In addition, the package unloading device 40 of the present embodiment is used for recovering the winding packages P in the fourth and fifth stages. The worker may directly retrieve the rewinding package P from the first stage to the third stage from the stocker 27 at a point lower than the fourth stage and the fifth stage. At that time, it is preferable to move the package unloading device 40 to a position away from the winding table 3 of the package collection target so as not to interfere with the collection operation.

The package unloading device 40 of the present embodiment can easily lower the package P at a higher position by moving the package receiver 43 over the upper receiving position and the lower receiving position. In addition, since the main body frame 41 can be moved in the arrangement direction of the winding table 3, the winding package P of the plurality of winding tables 3 can be lowered by one common package unloading device 40 .

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, the main frame (41) is prevented from collapsing during the work of lowering the package (P). The connecting portion 55 is movably connected to the upper rail 33 extending over the upper portions of the plurality of wind- Therefore, even when the main frame 41 is moved in the longitudinal direction, the main frame 41 is prevented from collapsing.

Especially, in this embodiment, the height of the main body frame 41 is set to be high (for example, 3 m or more) in order to lower the winding package P from the stocker 27 at a high position. On the other hand, as shown in Fig. 1, it is difficult to enlarge the space 77 between the winding table 3 and the crill stand 4 from the viewpoint of suppressing the size of the twist processing machine 1 in the lateral direction. The dimension in the depth direction of the main body frame 41 (the lateral direction of the false twisting machine 1) is suppressed to be small in order to secure space for the package recovery operation even in the limited space 77 (for example, 0.8 m or less).

That is, the body frame 41 is a structure having a small depth and a high height. Therefore, when a plurality of rewinding packages P each having a large weight are placed on the package receiver 43 at the upper receiving position, the balance is poor and the package unloading apparatus 40 may fall in the left and right directions. In this respect, the configuration of the present embodiment in which the upper end of the main body frame 41 is connected to the winding table 3 is very useful in reliably preventing the main body frame 41 from falling down.

The body frame 41 is provided with a cover 45 that moves over the closed position and the open position. Therefore, when the package receiver 43 at the collection position is moved to the upper receiving position, the operator unintentionally picks up his or her hand near the package receiver 43 immediately before the cover 45 is moved upward by setting the cover 45 to the closed position It is possible to prevent it from being inserted. On the other hand, when the package P is received and returned to the return position, the package 45 can be taken out of the package receiver 43 with the cover 45 as the open position.

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, the lifting of the package receiver 43 by the air hoist 44 is permitted only when the cover 45 is in the closed position. That is, when the cover 45 is in the open position and the package receiver 43 at the return position is not covered with the cover 45, the package receiver 43 is not moved to the receiving position. Therefore, it is possible to reliably prevent the operator from accidentally putting his / her hand or the like in the vicinity of the package receiver 43 immediately before moving upward.

The package unloading device 40 has a fixing device 42 that fixes the main body frame 41 in the longitudinal direction in a non-movable manner. The main frame 41 is fixed by the fixing device 42 so that the main frame 41 is prevented from moving in the forward and backward directions during the operation of lowering the package P from above.

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

Further, in the package unloading apparatus 40 of the present embodiment, the package can be lowered from the stocker at a position of 2.3 m or more from the bottom surface, which is hard to reach by the hand of the operator.

The package unloading device 40 of the present embodiment allows the operator to operate the lever 74 of the operation box 46 or the pendant switch 47 or the like so that the air cylinder 59 of the package receiver 43, The air hoist 44 is operated to lower the winding package P 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, since the worker can operate the pendant switch 47 or the like to lower the winding package P from the stocker 27 at a high position, the work load can be reduced. On the other hand, since the operator ascertains the circumstance, the package receiver 43 is moved up and down. Therefore, safety is high in comparison with a device that automatically collects the package P from the standpoint of coping with unexpected troubles. In addition, it is sufficient to provide only the minimum necessary driving portion for lowering the wind-up package P such as the air hoist 44, and it is advantageous in terms of cost and energy saving compared with a fully automatic device.

Next, a modification mode in which various modifications are added to the above embodiment will be described. However, those having the same configuration as those of the above-described embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

1] In the above embodiment, the upper rail 33 is provided on the upper portion of the plurality of winding tables 3 so that the connecting portion 55 of the package unloading apparatus 40 is movable along the upper rail 33 . However, the upper rail 33 is not essential from the viewpoint of preventing the collapse of the apparatus during package unloading operation. That is, the package unloading device may be connected to the upper end of the winding table 3 by the connecting portion when the package unloading device is moved to the workpiece winding table 3. That is, each time the package unloading apparatus is moved / stopped, the connection to the winding table 3 may be disconnected.

2] The lower rails 30 extending over the lower portions of the plurality of winding tables 3 are also not essential. For example, the package unloading apparatus may have a plurality of tires, and the tires may freely run on the floor. In this case, it is possible to commonly use one package unloading apparatus for a plurality of false twisting machines 1 by moving the package unloading apparatus between the plurality of false twisters 1.

3] The cover is not limited to the configuration of the above embodiment. For example, there is no particular need for a shutter type shutter in which the cover moves in the vertical direction, and it may be a door type that swings toward the front side of the operator.

4] As for the package receiver of the package unloading apparatus, for example, the following changes are possible.

The package receiver 43 of the above embodiment receives the package P from the fourth and fifth tiers (uppermost stage) of the winding table. However, only the uppermost tier 27 stores the package P May be received.

The package receiver 43 of the above-described embodiment receives four wrapping packages P arranged at the front and rear in each stage at once, but the number of the wrapping packages P received by the package receiver at one time can be appropriately changed . For example, even when four stackers 27 are arranged at each end of the winding table 3, the package receiver may receive the wrapping package P only from the two stockers 27. That is, the four winding packages P in each stage may be received in two parts.

The package receiver 43 of the package unloading device 40 of the above embodiment has a configuration capable of receiving the winding package P from the upper and lower two stages of the stocker 27 of the winding table 3, It is also possible to adopt a configuration capable of simultaneously receiving the winding package P from the stocker 27. [ That is, the package receiver may have three or more package receivers 58 arranged vertically. Alternatively, as opposed to the above, the package receiver may receive the winding package P from only the single-stage stocker 27.

5] The package unloading apparatus 40 of the above embodiment is an air drive type apparatus that operates by receiving supply of air from an air supply source on the winding table 3 side. On the contrary, the package unloading apparatus may be a motor type apparatus having a motor (a lifting drive section of the present invention) for lifting up and down the package receiver and driving the motor by receiving power from the power supply on the winding table 3 side. In the case of the electric type, the package unloading device may be provided with a dedicated power source.

6] The fixing device for fixing the position of the package unloading device need not be provided in the package unloading device, but may be provided on the winding table 3 or the floor.

It is not essential that the package unloading apparatus is connected to the power supply section (the air supply section 38 in the above embodiment) of the winding unit side in conjunction with the operation of the fixing apparatus 42, A connection operation with the power supply unit may be separately performed.

8] The package unloading device 40 of the above embodiment receives the winding package P from the winding table 3 with the winding device 22 attached thereto and drops it downward. On the other hand, the winding package P formed in the winding device may be mounted on a base (package base) different from the winding table. In this case, the package unloading device receives the winding package P from the package side, not from the winding stage with the winding device attached.

9] In the general twisting machine 1, since many winding bobbins 3 are arranged in the front-rear direction, if there is only one package unloading device 1, it is considered that waiting time for the package unloading operation will occur. Therefore, a plurality of package unloading devices may be provided for one piece of the twisting machine 1.

In the above description, the present invention is applied to a twisting machine, but the present invention can be applied to a textile machine other than a twisting machine for winding a yarn on a bobbin to form a winding package.
