[Problem to be Solved by the Invention]

Empty paper tubes are appropriately replenished to the empty paper tube supply device by workers, automatic robots, or the like. Here, when the empty paper tubes stored in the empty paper tube supply device are exhausted but the empty paper tubes are forgotten to be replenished, the empty paper tubes cannot be supplied from the empty paper tube supply device to the winding device. In the false twist processing machine, the yarn is continuously supplied from the yarn supply section. Therefore, if the empty paper tube is not supplied to the winding device after the full package is unloaded from the winding device, since the thread is continuously supplied from the thread supply part, there is a possibility that the thread is entangled in the winding device or the like. bad situation.

In addition, when the yarn breaks in the middle of winding the yarn or fails to catch the yarn to the winding device, the winding of the winding device may be interrupted midway and the supply of the next empty paper tube may be requested in advance. In this case, if the empty paper tube is not stored in the empty paper tube supply device, the above-mentioned inconvenience may occur, and it is necessary to grasp the timing of replenishing the empty paper tube to the empty paper tube supply device.

In particular, in a false twist processing machine having a plurality of coilers, it is difficult to know when to replenish empty paper tubes for all the empty paper tube supply devices corresponding to each coiler, and it is easy to forget to replenish empty paper tubes. [Means used to solve the problem]

An object of the present invention is to provide a false twisting machine capable of suppressing forgetting to replenish empty paper tubes to an empty paper tube supply device and suppressing failure of a winding device to wind a yarn.

Moreover, the false twist processing machine 1 has the main body 8 and the winding table 9 arrange|positioned at intervals in the machine width direction. The main body 8 and the take-up table 9 extend in the body length direction to approximately the same length, and are arranged to face each other. The upper part of the main body 8 and the upper part of the winding table 9 are connected by the support frame 10. Each device constituting the processing unit 3 is mainly attached to the main body 8 and the support frame 10 . The main body 8 , the winding table 9 , and the support frame 10 form a work space 22 for an operator to carry out work such as threading on each device. The wire passage is formed so that the wire Y runs mainly around the working space 22 .

The false twist processing machine 1 has a unit unit called a span including a set of a main body 8 and a winding table 9 arranged to face each other. In one span, each device is arranged so that false twisting can be performed simultaneously on a plurality of yarns Y running in a state aligned in the longitudinal direction of the machine body. As an example, twelve winding devices 21 are installed on one winding table 9 (see FIG. 2 ). In addition, the false twist processing machine 1 is configured such that the span is arranged symmetrically on the left and right sides of the paper with the center line C in the machine width direction of the main body 8 as the axis of symmetry (the main body 8 is common in the left and right spans), and in the body length direction There are several listed above.

(Structure of processing department) Next, each constituent element of the processing part 3 is demonstrated. The first yarn supply roller 11 is used to convey the yarn Y supplied from the yarn supply unit 2 to the first heating device 13 . The first yarn supply roll 11 is arranged above the winding table 9 (see FIG. 1 ). The first yarn supply rollers 11 are arranged in one row in the machine body longitudinal direction.

The anti-twist guide 12 is used to prevent the twist imparted to the yarn Y by a false twist device 15 to be described later from propagating to a position upstream of the anti-twist guide 12 in the yarn traveling direction. The anti-twist guide 12 is disposed on the downstream side of the first yarn supply roller 11 in the yarn traveling direction and on the upstream side of the first heating device 13 in the yarn traveling direction. The anti-twist guides 12 are provided independently of, for example, the plurality of yarns Y supplied from the yarn supply unit 2, and are arranged in one row in the machine longitudinal direction.

The first heating device 13 is for heating the yarn Y fed from the first yarn supply roll 11, and is installed on the support frame 10 (see FIG. 1). A plurality of first heating devices 13 are provided for the plurality of yarns Y supplied from the yarn supply unit 2, and are arranged in one row in the body longitudinal direction.

The cooling device 14 is for cooling the yarn Y heated by the first heating device 13 . The cooling device 14 is disposed on the downstream side of the first heating device 13 in the yarn running direction and on the upstream side of the false twisting device 15 in the yarn running direction. A plurality of cooling devices 14 are provided for the plurality of yarns Y supplied from the yarn supply unit 2, and are arranged in one row in the body longitudinal direction.

The false twisting device 15 is a device for twisting the yarn Y. The false twisting device 15 is disposed immediately downstream of the cooling device 14 in the yarn traveling direction. A plurality of false twisting devices 15 are arranged in the length direction of the machine body. For example, 12 false twist devices 15 are provided for one span.

The second yarn supply roller 16 is a roller that conveys the yarn Y twisted by the false twisting device 15 toward the interlacing device 17 . The second yarn supply roller 16 is arranged on the downstream side of the false twisting device 15 in the yarn traveling direction in the main body 8 . The feed speed of the yarn Y fed by the second yarn supply roller 16 is faster than the feed speed of the yarn Y fed by the first yarn feed roller 11 . Therefore, the yarn Y is stretched between the first yarn supply roller 11 and the second yarn supply roller 16 .

The entanglement device 17 is a device for imparting entanglement by injecting air to the yarn Y. The interlacing device 17 is disposed below the second yarn supply roll 16 in the main body 8 .

The third yarn supply roll 18 is a roll that feeds the yarn Y entangled by the entanglement device 17 toward the second heating device 19 . The third yarn supply roll 18 is disposed below the interlacing device 17 in the main body 8 . The feed speed of the yarn Y fed by the third yarn supply roller 18 is slower than the feed speed of the yarn Y fed by the second yarn feed roller 16 . Therefore, the yarn Y is loosened between the second yarn supply roller 16 and the third yarn supply roller 18 .

The second heating device 19 is a device for heating the yarn Y fed from the third yarn supply roller 18 . The second heating device 19 is arranged below the third yarn supply roller 18 in the main body 8 . The second heating devices 19 extend in the vertical direction, and are provided one at a time in each span.

The fourth yarn supply roller 20 is a roller that conveys the yarn Y heat-treated by the second heating device 19 toward the winding device 21 . The fourth yarn supply roll 20 is disposed below the winding table 9 . The feeding speed at which the fourth yarn supply roller 20 feeds the yarn Y is slower than the feeding speed at which the third yarn supply roller 18 feeds the yarn Y. Therefore, the yarn Y is loosened between the third yarn supply roller 18 and the fourth yarn supply roller 20 .

In the processing section 3 configured as described above, the yarn Y stretched between the first yarn supply roller 11 and the second yarn supply roller 16 is twisted by the false twisting device 15 . The twist formed by the false twist device 15 propagates to the anti-twist guide 12, but does not propagate upstream of the anti-twist guide 12 in the yarn traveling direction. The yarn Y twisted while being stretched is cooled by the cooling device 14 after being heated and heat-set by the first heating device 13 . The yarn Y is untwisted downstream of the false twisting device 15, but each filament remains false twisted into a wavy state by the heat setting described above. The yarn Y subjected to false twisting by the false twisting device 15 is entangled by the entangling device 17 while being relaxed between the second yarn supply roller 16 and the third yarn supply roller 18, and is transported downstream in the yarn traveling direction. side boot. Furthermore, the yarn Y is heat-set by the second heating device 19 while being relaxed between the third yarn supply roller 18 and the fourth yarn supply roller 20 . Finally, the yarn Y delivered from the fourth yarn supply roller 20 is wound up by the winding device 21 to form a winding package Pw.

(Structure of winding section 4) Next, the configuration of the winding unit 4 will be described with reference to FIGS. 2 and 3 . As shown in FIG. 3 , the winding section 4 has a plurality of winding devices 21 for winding the yarn Y around the winding bobbin Bw to form a winding package Pw, and a plurality of empty bobbin supplying devices 23 (empty bobbin in the present invention). paper tube feeding device), and a plurality of storage parts 24. The plurality of empty bobbin supply devices 23 and the plurality of storage units 24 are provided one for each of the plurality of winding devices 21 . Each winding device 21 has a single cradle 31 that rotatably supports the winding bobbin Bw. The winding bobbin Bw supported by the cradle 31 is rotationally driven by, for example, a motor not shown. The winding device 21 winds the yarn Y around the winding bobbin Bw by rotationally driving the winding bobbin Bw to form a winding package Pw.

The empty bobbin supply device 23 is a device for supplying an empty winding bobbin Bw in a state where the yarn Y is not wound to the winding device 21 . In addition, an empty winding bobbin Bw (hereinafter referred to as an empty bobbin Bw) corresponds to the empty paper bobbin of the present invention. The details of the empty bobbin supply device 23 will be described later.

The storage unit 24 stores the fully wound winding package Pw formed by the winding device 21 . When the winding package Pw is fully wound, the cradle 31 rotates around the rotation axis along the longitudinal direction of the body, thereby detaching the winding bobbin Bw supported by the cradle 31 from the winding device 21 and moving it to the winding device 21. The storage unit 24 supplies. For example, the storage unit 24 can store up to three wound packages Pw. In addition, even if the winding package Pw is not fully wound, the winding package Pw can be supplied to the storage part 24 even if the winding device 21 breaks the yarn Y during winding of the yarn Y.

(Structure of empty bobbin supply device 23) Next, the configuration of the empty bobbin supply device 23 will be described with reference to FIG. 4 . The empty bobbin supply device 23 is a device for supplying the empty bobbin Bw to the winding device 21 after the winding package Pw is unloaded from the winding device 21 and supplied to the storage part 24 . Each empty bobbin supply device 23 has a storage unit 51 capable of storing four empty bobbins Bw, a first sensor 52 , a second sensor 53 , and a tip member 54 .

The storage portion 51 has a support member 51a and a side wall 51b. The support member 51a is a member that supports the empty bobbin Bw from below, and is inclined downward toward the side where the winding device 21 is arranged in the body width direction. The supporting member 51a is formed such that the length in the body longitudinal direction is slightly longer than the length along the axis of the empty bobbin Bw. The side wall 51b is a member extending upward from one end and the other end of the supporting member 51a in the body longitudinal direction. In addition, in FIG. 4 , only the side wall 51b on the rear side of the empty bobbin Bw supported by the support member 51a is shown, but actually the side wall 51b is also provided on the front side of the empty bobbin Bw on the paper. In the present embodiment, the storage unit 51 can store up to four empty bobbins Bw. In this embodiment, the empty bobbin Bw is replenished to the storage part 51 by manual operation by an operator. The empty bobbin Bw replenished by the worker to the storage portion 51 moves along the downwardly inclined support member 51a toward the side in the body width direction where the winding device 21 is disposed. The first empty bobbin Bw stored in the storage unit 51 moves along the inclination of the support member 51a, and is positioned at the end of the storage unit 51 on the side where the winding device 21 is disposed in the body width direction. In the state where the first empty bobbin Bw is stored in the storage part 51, the second to fourth empty bobbins Bw to be supplemented move along the inclination of the storage part 51, and the second, third and fourth empty bobbins Bw are moved along the inclination of the storage part 51. The bobbins Bw are located next to the first empty bobbin Bw in turn. Hereinafter, the first empty bobbin Bw, the second empty bobbin Bw, the third empty bobbin Bw, and the fourth empty bobbin Bw are called in order from the side close to the winding device 21 .

The first sensor 52 is a microswitch having a detection piece 52a protruding slightly upward from the bottom surface of the supporting member 51a. Moreover, the 2nd sensor 53 is a microswitch which has the detection piece 53a which protrudes slightly upward from the bottom surface of the support member 51a. The first sensor 52 is turned on when the empty bobbin Bw is in contact with the detection piece 52a, and is turned off when the empty bobbin Bw is not in contact with the detection piece 52a. The second sensor 53 is turned on when the empty bobbin Bw is in contact with the detection piece 53a, and is turned off when the empty bobbin Bw is not in contact with the detection piece 53a. In addition, the 1st sensor 52 and the 2nd sensor 53 are not limited to microswitches, An infrared sensor etc. which detect an empty bobbin Bw by irradiating infrared rays may be sufficient.

The detection piece 52a of the first sensor 52 is arranged at a position where the third empty bobbin Bw can be contacted. Therefore, when the first sensor 52 is turned on, it indicates that the number of empty bobbins Bw stored in the storage unit 51 is three or more. In addition, when the first sensor 52 is turned off, it indicates that the stored number of empty bobbins Bw is 2 or less. That is, the first sensor 52 of the present embodiment can detect that the number of empty bobbins Bw stored in the storage unit 51 is two or less, and corresponds to the first sensor of the present invention.

The detection piece 53a of the second sensor 53 is arranged at a position where the second empty bobbin Bw can be contacted. Therefore, when the second sensor 53 is turned on, it indicates that the number of empty bobbins Bw stored in the storage unit 51 is two or more. In addition, when the second sensor 53 is turned off, it indicates that the stored number of empty bobbins Bw is one or less. That is, the second sensor 53 in this case of the present embodiment can detect that the number of empty bobbin tubes Bw stored in the storage unit 51 is one or less than the predetermined number, and can be regarded as the first embodiment of the present invention. sensor.

Also, the control unit 40 can determine whether the number of empty bobbins Bw stored in the storage unit 51 is one or zero based on the on-off switching timing of the second sensor 53 . Hereinafter, a configuration in which the control unit 40 determines the number of stored empty bobbins Bw based on the detection by the second sensor 53 will be described.

The empty bobbins Bw are supplied from the empty bobbin supply device 23 to the winding device 21 one by one. In addition, once the empty bobbin Bw is supplied from the empty bobbin supply device 23 to the winding device 21, the next empty bobbin Bw is not processed until the winding package Pw is fully wound and unloaded from the winding device 21. supply. For example, the control unit 40 pre-calculates the time period from when the empty bobbin supply device 23 supplies the empty bobbin Bw to the winding device 21 to when the winding package Pw becomes full and is unloaded from the winding device 21 and unloaded from the winding device 21 as a predetermined time. The time until one empty bobbin Bw is supplied to the take-up device 21 . In addition, the predetermined time is not limited to being calculated by the control unit 40, and may be input by an operator in advance.

When the second sensor 53 is turned off and is switched from on to off within the predetermined time immediately before, the control unit 40 determines that the sensor is stored in the storage unit 51 within the predetermined time immediately before. The storage number of empty bobbins Bw is changed from two to one. Thereby, the control part 40 can judge that the storage number of the empty bobbin Bw stored in the storage part 51 is one.

On the other hand, the control unit 40 determines that the number of empty bobbins Bw stored in the storage unit 51 has changed from 2 to After one, the empty bobbin Bw is further supplied to the winding device 21 so that the number of stored tubes becomes zero. Accordingly, the control unit 40 can determine that the number of empty bobbins Bw stored in the storage unit 51 is zero. Therefore, the second sensor 53 of the present embodiment can detect that the number of empty bobbins Bw stored in the storage unit 51 is zero, and corresponds to the second sensor of the present invention.

In addition, in the present embodiment, when the first sensor 52 does not detect the empty bobbin Bw but the second sensor 53 detects the empty bobbin Bw, the empty bobbin stored in the storage unit 51 can be detected. Consider the case where the stored number of Bw is two.

The front-end member 54 is provided at the front-end|tip of the storage part 51 on the side where the winding device 21 is arrange|positioned in the machine width direction. The empty bobbin Bw moving along the supporting member 51a inclined downward is restricted from being supplied to the winding device 21 from the leading end of the storing part 51 on the side where the winding device 21 is arranged by contacting the leading end member 54 .

Hereinafter, a configuration in which the empty bobbin Bw is supplied from the empty bobbin supply device 23 to the winding device 21 will be described. During the winding operation of the yarn Y by the winding device 21, the empty bobbin supply device 23 is in a standby position where the movement of the empty bobbin Bw can be restricted by the front end member 54 (see FIG. 3 ). When the fully wound winding package Pw formed by the winding device 21 is unloaded from the winding device 21 by the rotation of the cradle 31, the empty bobbin supply device 23 moves to supply the empty bobbin to the winding device 21.

Accordingly, by providing two sensors, it is possible to grasp the number of empty bobbins Bw stored in the storage unit 51 in more detail. Therefore, it is easy to freely adjust the timing of the notification that the empty bobbin Bw needs to be replenished according to the situation on the spot or the like.

(Modification) As mentioned above, although preferred embodiment of this invention was demonstrated, this invention is not limited to these examples, As long as it describes in the claim, various changes are possible. Hereinafter, modifications to the above-described embodiment will be described. However, components having the same configuration as those in the above-mentioned embodiment are denoted by the same reference numerals and their descriptions are appropriately omitted.

In the above-mentioned embodiment, the control unit 40 sends a notification signal to the notification unit 61 to cause the notification operation to be executed. However, the control unit 40 may transmit the notification signal to a device different from the notification unit 61 . For example, in the false twisting machine 101, the control unit 140 sends a notification signal to the empty bobbin replenishment robot 161 (the empty paper tube replenishment robot of the present invention) (see FIG. 6 ). The empty bobbin replenishment robot 161 is a device capable of automatically replenishing the empty bobbin Bw to the storage unit 51 . The empty bobbin replenishment robot 161 is, for example, a robot capable of reciprocating along the longitudinal direction of the body, and automatically replenishing empty bobbins Bw to each storage unit 51 by operating a robot arm, a conveyor, or the like. The control unit 140 sends a notification signal to the empty bobbin replenishing robot 161 to cause it to perform the replenishment operation of the empty bobbin Bw. According to this configuration, when the empty bobbin replenishment robot 161 automatically replenishes the empty bobbin Bw to the storage unit 51, the timing of the replenishment operation can be appropriately controlled.

In addition, in the false twisting machine 101 having the empty bobbin replenishment robot 161, the empty bobbin supply device 123 may have a storage number of the empty bobbins Bw stored in the storage unit 51 that is the maximum number that the storage unit 51 can store. The third sensor 154 (refer to FIG. 7 ) that detects the situation. The detection piece 154a of the third sensor 154 is arranged at a position where the fourth empty bobbin Bw can be contacted. When the third sensor 154 is turned on, it indicates that the number of empty bobbins Bw stored in the storage unit 51 is four. In addition, when the third sensor 154 is turned off, it indicates that the stored number of empty bobbins Bw is three or less. That is, the third sensor 154 in this case can detect that the number of empty bobbins Bw stored in the storage unit 51 is three of the predetermined number, and can be regarded as the first sensor of the present invention. Also, the third sensor 154 can detect that the number of stored empty bobbins Bw is four which is the maximum number that can be stored, and corresponds to the third sensor of the present invention.

The control unit 140 controls so that the empty bobbin replenishment robot 161 does not perform the replenishment operation when the third sensor 154 detects that the number of empty bobbins Bw stored in the storage unit 51 is the maximum. According to this configuration, when the empty bobbins Bw are automatically replenished to the storage unit 51 by the empty bobbin replenishment robot 161 , it is possible to prevent the replenishment operation from being performed when the storage unit 51 stores the largest number of empty bobbins Bw. Accordingly, it is possible to prevent the empty bobbin Bw from overflowing from the storage portion 51 .

In addition, the control unit 140 may cause the empty bobbin replenishment robot 161 to perform the replenishment operation until the third sensor 154 detects that the number of stored empty bobbins Bw reaches the maximum. Accordingly, when the empty bobbins Bw are automatically replenished to the storage unit 51 by the empty bobbin replenishing robot 161, the maximum number of empty bobbins Bw can be replenished by one replenishment operation.

In the above-described embodiment, a third sensor 154 may also be provided. In this case, the control unit 40 may cause the notification unit 61 to execute notification that the number of empty bobbins Bw stored in the storage unit 51 cannot be sent to the storage unit 51 when the third sensor 154 detects that the number of empty bobbins Bw stored in the storage unit 51 is the maximum. It is an action to replenish the empty bobbin Bw at the end.

In the above embodiment, the second sensor 53 may be provided at a position where the first empty bobbin Bw can be detected when one or more empty bobbins Bw are stored in the storage unit 51 . In this case, the second sensor 53 is a sensor that detects whether the number of empty bobbins Bw stored in the storage unit 51 is one or more and zero. That is, the second sensor 53 in this case corresponds to the second sensor of the present invention.

Furthermore, in the present invention, the empty bobbin supply device 23 may have four sensors. In this case, the four sensors are provided one at each of four positions where the first to fourth empty bobbins Bw can be detected when four empty bobbins Bw are stored in the storage unit 51 . Furthermore, the empty tube supply device 23 can also have only one sensor.

In the above embodiment, the control unit 40 may generate the notification signal only when the first sensor 52 detects that the number of empty bobbins Bw stored in the storage unit 51 is two or less. In addition, the control unit 40 may generate the notification signal only when the second sensor 53 detects that the number of empty bobbins Bw stored in the storage unit 51 is one or less. Furthermore, the control unit 40 may generate a notification signal only when the second sensor 53 detects that the storage number of empty bobbins Bw stored in the storage unit 51 is zero. In short, the control unit 40 generates a notification when one or both of the first sensor 52 and the second sensor 53 detects that the number of empty bobbins Bw stored in the storage unit 51 is less than a predetermined number. signal, and make the notification unit 61 execute the notification action. The timing at which the control unit 40 generates the notification signal is set in advance according to the number of installations of the empty bobbin supply device 23 for each false twisting machine 1 or the number of workers who replenish the empty bobbins Bw, etc. The point of time when the empty bobbin Bw is forgotten to be replenished can be suppressed to the greatest extent.

In the above embodiment, the control unit 40 generates a priority notification signal when the second sensor 53 detects that the number of empty bobbins Bw stored in the storage unit 51 is zero. However, the control unit 40 may generate a normal notification signal instead of a priority notification signal when the second sensor 53 detects that the number of empty bobbins Bw stored in the storage unit 51 is 0.

In the above-described embodiment, the storage unit 51 can accommodate four empty bobbins Bw. However, the storage unit 51 may be able to store two or three empty bobbins Bw, or may be able to store five or more empty bobbins Bw. In addition, sensors may be provided according to the number of empty bobbins Bw that can be stored in the storage unit 51 . For example, when the storage unit 51 can accommodate two or more empty bobbins Bw, ie, n empty bobbins Bw, n sensors may be provided. In this case, the n sensors are provided one for each of n positions capable of detecting the first to n-th empty bobbins Bw when n empty bobbins Bw are stored in the storage unit 51 . In addition, when the storage part 51 can store n empty bobbin tubes Bw, the sensor of any number among 1-n-1 may be provided.

In the above-described embodiment, the notification unit 61 is a monitor electrically connected to each empty bobbin supply device 23 . However, the notification unit 61 may be, for example, a lamp attached to each empty bobbin supply device 23 . In this case, the control unit 40 transmits the notification signal to the notification unit 61, thereby turning on the lamp of the notification unit 61 corresponding to the storage unit 51 whose storage number of empty bobbins Bw is equal to or less than a predetermined number. The operator can grasp that it is necessary to replenish the empty bobbin Bw to the storage portion 51 of the empty bobbin supply device 23 corresponding to the lamp that is turned on. In addition, the control unit 40 may make the color of the lamp turned on by the notification unit 61 different when a priority notification signal is sent to the notification unit 61 and when a normal notification signal other than the priority notification signal is sent. Accordingly, it is possible to distinguish whether the notification operation of the notification unit 61 is performed upon receipt of a priority notification signal or an operation performed upon receipt of a normal notification signal that is not a priority notification signal.

In addition, the notification unit 61 may be, for example, a device that emits sound. In this case, the notification unit 61 may be attached to each empty bobbin supply device 23 , or may be a single notification unit 61 common to a plurality of empty bobbin supply devices 23 . When the notification unit 61 is attached to each empty bobbin supply device 23, the control unit 40 sends a notification signal to the notification unit 61, thereby corresponding to the storage unit 51 whose storage number of empty bobbins Bw is equal to or less than a predetermined number. The notification section 61 produces sound. In the case where the notification unit 61 is one notification unit 61 common to a plurality of empty bobbin supply devices 23, the control unit 40 sends a notification signal to the notification unit 61, thereby causing the notification unit 61 to determine which storage unit 51 is empty. The sound notified by the storage unit 51 that the number of stored bobbins Bw has become less than or equal to a predetermined number. In addition, the control part 40 may make the sound pattern which the notification part 61 emits differ between the case of sending a priority notification signal to the notification part 61, and the case of sending a normal notification signal which is not a priority notification signal. Accordingly, it is possible to distinguish whether the notification operation of the notification unit 61 is performed upon receipt of a priority notification signal or an operation performed upon receipt of a normal notification signal that is not a priority notification signal.
