Accordingly, the operation efficiency of the winding unit, the assisting unit, and the like can be improved.
- the signal restoring device that restores the electronic signals since the signal restoring device that restores the electronic signals is arranged on the communication path, the electronic signals can be reliably transmitted. Accordingly, the operation efficiency of the winding unit, the assisting unit, and the like can be improved.

- the automatic winder 100 further includes a signal control device 18 on the third communication path 17c. That is, the signal control device 18 is arranged between the group connected by the first communication path G1 and the group connected by the second communication path G2.
- the signal control device 18 is an information communication device adapted to select whether to transmit or shield an electronic signal in accordance with a transmitting destination of the electronic signal. That is, the signal control device 18 switches between transmission and shielding of the electronic signal depending on whether the transmitting destination of the electronic signal to pass is the winding unit 11, the assisting unit 16, the first control section 14a, or the second control section 14b. Since the electronic signal that is not required to be transmitted is shielded by the signal control device 18, the number of electronic signals to be processed by the winding unit 11, the assisting unit 16, the first control section 14a, and the second control section 14b is reduced.

- An electronic signal indicating that the package P is in a fully-wound state is transmitted from the winding unit 11 to the doffing device 13.

- the assisting unit 16 such as the doffing device 13 and the package conveyor is data linked to each other, and hence the capacity of the electronic signal transmitted from the second control section 14b to the assisting unit 16 becomes large. Therefore, if the electronic signal transmitted from the second control section 14b to the assisting unit 16 is transmitted to the group G1 without being shielded by the signal control device 18, the transmission and reception of the electronic signals in the group G1 is greatly delayed.
- the delay of the electronic signal in the group G1 can be reduced since the signal control device 18 shields the transmission of the electronic signal to the group G1 when transmitting the electronic signal from the group G2 only to the relevant group G2.
- the signal control device 18 shields the electronic signal. That is, the signal control device 18 prevents the electronic signal from being transmitted into the group connected with the first communication path G1, so that reduction of the delay in the electronic signal processing is achieved. Meanwhile, in the group G1, the electronic signal of the current operation state or the like can be transmitted from the winding unit 11 to the first control section 14a, for example.
- the electronic signal indicating that the collection of the package P and the attachment of the next winding bobbin B2 are completed is transmitted from the doffing device 13 to the winding unit 11.

- the electronic signal transmitted from the first control section 14a is transmitted to the winding unit 11 via the first communication path 17a.
- the signal control device 18 shields the electronic signal. That is, the signal control device 18 prevents the electronic signal from being transmitted to the group connected with the second communication path G2, so that reduction of the delay in the electronic signal processing is achieved. Meanwhile, in the group G2, the electronic signal indicating to prohibit the doffing device can be transmitted from the second control section 14b to the doffing device 13, for example.
- the electronic signal related to the winding condition of the winding unit 11 includes items related to winding speed, yarn count, winding tension, winding amount of winding package, and package weight.
- the electronic signal transmitted from the group G1 only to the relevant group G1 includes information related to the winding state transmitted from the winding unit 11 to the first control section 14a.
- This information includes package diameter, winding speed, occurrence situation of yarn cut, detection situation of yarn defect, and the like.
- the information is sequentially transmitted from the winding unit 11 to the first control section 14a during the operation of the winding unit 11.

- the spinning machine 200 further includes a signal control device 28 on the third communication path 27c. That is, the signal control device 28 is arranged between the group connected by the first communication path G1 and the group connected by the second communication path G2.
- the signal control device 28 is an information communication device adapted to select whether to transmit or shield an electronic signal in accordance with a transmitting destination of the electronic signal. That is, the signal control device 28 switches between transmission and shielding of the electronic signal depending on whether the transmitting destination of the electronic signal to pass is the winding unit 21, the assisting unit 26, the first control section 24a, or the second control section 24b. Since the electronic signal that is not required to be transmitted is shielded by the signal control device 28, the number of electronic signals to be processed by the winding unit 21, the assisting unit 26, the first control section 24a, and the second control section 24b is reduced.

Note that a control mode described below is merely an example, and the present invention is not limited thereto.
- An electronic signal indicating that the package P is in a fully-wound state is transmitted from the winding unit 21 to the doffing device 23.

- the assisting unit 26 such as the doffing device 23 and the package conveyor is data linked to each other, and hence the capacity of the electronic signal transmitted from the second control section 24b to the assisting unit 26 becomes large. Therefore, if the electronic signal transmitted from the second control section 24b to the assisting unit 26 is transmitted to the group G1 without being shielded by the signal control device 28, the transmission and reception of the electronic signals in the group G1 is greatly delayed.

- The inventors of the present invention have made the following invention focusing on the fact that electronic signals transmitted and received among the winding unit, the assisting unit, and the control device can be divided into three: (1) the electronic signal that is required to be transmitted between the winding unit and the control device but is not required to be transmitted to the assisting unit; (2) the electronic signal that is required to be transmitted between the assisting unit and the control device but is not required to be transmitted to the winding unit; and (3) the electronic signal that is required to be transmitted between the winding unit and the assisting unit but is not required to be transmitted to the control device.
- A first aspect of the invention relates to a yarn winding machine including a winding unit that winds a yarn to form a package; an assisting unit that assists the winding unit in forming the package; a first control section that receives an electronic signal from the winding unit and the assisting unit and transmits an electronic signal to the winding unit and the assisting unit; a second control section that receives an electronic signal from the winding unit and the assisting unit and transmits an electronic signal to the winding unit and the assisting unit; and a communication path that connects the winding unit, the assisting unit, the first control section, and the second control section to be communicable with each other, wherein a signal control device is arranged on the communication path, and the signal control device selects whether to transmit or shield the electronic signal in accordance with a transmitting destination of the electronic signal.
- According to a second aspect of the invention, in the yarn winding machine according to the first aspect, the communication path is sectionalized into a first communication path that connects the winding unit and the first control section to be communicable with each other, a second communication path that connects the assisting unit and the second control section to be communicable with each other, and a third communication path that connects a group connected with the first communication path and a group connected with the second communication path; and the signal control device is arranged on the third communication path.
- According to a third aspect of the invention, in the yarn winding machine according to the second aspect, the signal control device transmits the electronic signal when transmitting the electronic signal from the group connected with the first communication path to the group connected with the second communication path, and shields the electronic signal when transmitting the electronic signal from the group connected with the first communication path only to the relevant group.

Furthermore, in the present the yarn winding machine, since the winding unit, the assisting unit, the first control section, and the second control section are connected with one communication path and then the control of electronic signals is carried out, maintenance can be performed more easily and inexpensively compared to the case where they are connected with a plurality of communication paths.

Accordingly, the operation efficiency of the winding unit, the assisting unit, and the like can be improved.
- According to the fifth aspect, since the winding unit and the assisting unit can communicate with each other without interposing the first control section and the second control section, the transmission speed of the electronic signals is improved. Accordingly, the operation efficiency of the winding unit, the assisting unit, and the like can be improved.
- According to the sixth aspect, since the signal restoring device that restores the electronic signals is arranged on the communication path, the electronic signals can be reliably transmitted. Accordingly, the operation efficiency of the winding unit, the assisting unit, and the like can be improved.

FIG. 2 is a view illustrating a communication path of the automatic winder; -
FIG. 3 is a view illustrating an overall configuration of a spinning machine; and -
FIG. 4 is a view illustrating a communication path of the spinning machine. - First, an
automatic winder 100, which is a yarn winding machine according to one embodiment of the present invention, will be described. -

Theautomatic winder 100 is mainly configured by a plurality of windingunits 11, a yarn supplyingbobbin supplying device 12, a doffingdevice 13, a package conveyor (not illustrated), and acontrol device 14. - When a defected part is found in a yarn Y unwound from a yarn supplying bobbin B1, the winding
unit 11 regulates the yarn quality by removing the defected part. The windingunit 11 winds the yarn Y by rotating a winding bobbin B2, and forms a package P on the winding bobbin B2. The windingunit 11 thus regulates the yarn quality of the yarn Y and forms the package P by winding the yarn Y. - Each winding
unit 11 includes a windingunit control section 11a (seeFIG. 2 ). The windingunit control section 11a includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a communication port. The ROM stores a control program for controlling the operation of the windingunit 11. The CPU executes the control program stored in the ROM to enable the winding of the yarn Y to be appropriately carried out. - The communication port of the winding
unit control section 11a is connected to thecontrol device 14 and an assistingunit 16, thus enabling the transmission and reception of electronic signals (seeFIG. 2 ).

bobbin supplying device 12 includes aconveyor 12a extending in an arranging direction of the windingunits 11, and a yarn supplyingbobbin preparing device 15. Theconveyor 12a is installed on a front side and a rear side of the windingunit 11.

Theconveyor 12a installed on the rear side of the windingunit 11 transports the yarn supplying bobbin B1 to each windingunit 11 while being placed on the tray. Theconveyor 12a installed on the front side of the windingunit 11 transports the yarn supplying bobbin B1 discharged from each windingunit 11 to a predetermined position. Thus, the yarn supplyingbobbin supplying device 12 supplies the yarn supplying bobbin B1 to each windingunit 11, and also collects the yarn supplying bobbin B1 discharged from each windingunit 11. - The doffing
device 13 moves along arail 13a extending in the arranging direction of the windingunits 11. The doffingdevice 13 detaches the fully-wound package P from the windingunit 11, and attaches the next winding bobbin B2. Thus, the doffingdevice 13 can collect the fully-wound package P, and also enable the windingunit 11 to continuously form the package P. - The package conveyor extends in an arranging direction of the winding
units 11, and is intermittently operated so as to transport the fully-wound package P detached by the doffingdevice 13 to an end of theautomatic winder 100 in a longitudinal direction. - The yarn supplying
bobbin supplying device 12, the doffingdevice 13, and the package conveyor are devices that assist the windingunit 11 to form the package P. Therefore, in the present embodiment, the yarn supplyingbobbin supplying device 12, the doffingdevice 13, and the package conveyor are defined as the assistingunit 16 of the windingunit 11. However, the assistingunit 16 merely needs to be a device adapted to directly or indirectly assist the windingunit 11 to form the package P (e.g., yarn supplying bobbin preparing device 15), and is not limited to the yarn supplyingbobbin supplying device 12, the doffingdevice 13, and the package conveyor. - Each assisting
unit 16 includes an assistingunit control section 16a (seeFIG. 2 ). Similarly to the windingunit control section 11a, the assistingunit control section 16a includes a CPU, a ROM, a RAM, and a communication port.

The CPU executes the control program stored in the ROM to enable the bobbin supplying operation, the doffing operation, and the like to be appropriately carried out. - The communication port of the assisting
unit control section 16a is connected to thecontrol device 14 and the assistingunit 16, thus enabling the transmission and reception of the electronic signals (seeFIG. 2 ). Thecontrol device 14 thus can collectively carry out the operation control and the information management of the plurality of assistingunits 16 arranged in theautomatic winder 100. - The
control device 14 is configured by afirst control section 14a and asecond control section 14b (seeFIG. 2 ). Thefirst control section 14a and thesecond control section 14b are connected by the windingunit 11, the assistingunit 16, and a communication path 17 (seeFIG. 2 ). Similarly to the windingunit control section 11a, thefirst control section 14a and thesecond control section 14b respectively includes a CPU, a ROM, a RAM, and a communication port. - The communication ports of the
first control section 14a and thesecond control section 14b are connected to the communication port of the windingunit control section 11a and the communication port of the assistingunit control section 16a through the communication path 17 (seeFIG. 2 ). According to such a configuration, thecontrol device 14 can receive the electronic signal of the operation state and the like from the respective windingunit control section 11a and the respective assistingunit control section 16a, and can grasp the operation state of the windingunit 11 and the assistingunit 16. Thecontrol device 14 can also transmit the electronic signal of the operation condition and the like with respect to the respective windingunit control section 11a and the respective assistingunit control section 16a, and can set the operation state of the windingunit 11 and the assistingunit 16. - The
first control section 14a has an information collecting function of receiving electronic signals from the windingunit 11 and the assistingunit 16 and grasping the operation state, and a setting function of transmitting electronic signals to the windingunit 11 and the assistingunit 16, and setting the operation state. Thesecond control section 14b has a control function of receiving electronic signals from the windingunit 11 and the assistingunit 16 to carry out information processing, and transmitting electronic signals to the windingunit 11 and the assistingunit 16 to smoothly form the package P. However, the main functions of thefirst control section 14a and thesecond control section 14b are not limited thereto. - The electronic signal (operation condition or the like) transmitted to the winding
unit 11 includes, for example, winding speed, yarn count, winding tension, package winding amount, package weight, and the like. The electronic signal (operation state or the like) transmitted from the windingunit 11 includes, for example, package diameter, winding speed, yarn cut occurrence situation, alarm information, and the like. The set value transmitted to the windingunit 11 may be transmitted while individually specifying each windingunit 11, or may be collectively transmitted to all the windingunits 11. -
FIG. 2 is a view illustrating thecommunication path 17 of theautomatic winder 100. Thecommunication path 17 is mainly sectionalized into afirst communication path 17a, asecond communication path 17b, and athird communication path 17c. - The
first communication path 17a connects the windingunit 11 and thefirst control section 14a so as to be communicable with each other. Thus, thefirst communication path 17a can transmit an electronic signal transmitted from the windingunit 11 to thefirst control section 14a. Thefirst communication path 17a can also transmit an electronic signal transmitted from thefirst control section 14a to the windingunit 11. - The
second communication path 17b connects the assistingunit 16 and thesecond control section 14b so as to be communicable with each other. Thus, thesecond communication path 17b can transmit an electronic signal transmitted from the assistingunit 16 to thesecond control section 14b. Thesecond communication path 17b can also transmit an electronic signal transmitted from thesecond control section 14b to the assistingunit 16. - The
third communication path 17c connects a group connected by the first communication path G1 and a group connected by the second communication path G2 so as to be communicable with each other. Thus, thethird communication path 17c can transmit an electronic signal transmitted from the windingunit 11 to thesecond control section 14b. Thethird communication path 17c can also transmit an electronic signal transmitted from thesecond control section 14b to the windingunit 11. Furthermore, thethird communication path 17c can transmit an electronic signal transmitted from the assistingunit 16 to thefirst control section 14a. Thethird communication path 17c can also transmit an electronic signal transmitted from thefirst control section 14a to the assistingunit 16. That is, by connecting the group G1 configured by the windingunit 11 and thefirst control section 14a and the group G2 configured by the assistingunit 16 and thesecond control section 14b, thethird communication path 17c enables the windingunit 11, the assistingunit 16, thefirst control section 14a, and thesecond control section 14b to be able to transmit electronic signals with each other. - The
automatic winder 100 further includes asignal control device 18 on thethird communication path 17c. That is, thesignal control device 18 is arranged between the group connected by the first communication path G1 and the group connected by the second communication path G2. - The
signal control device 18 is an information communication device adapted to select whether to transmit or shield an electronic signal in accordance with a transmitting destination of the electronic signal. That is, thesignal control device 18 switches between transmission and shielding of the electronic signal depending on whether the transmitting destination of the electronic signal to pass is the windingunit 11, the assistingunit 16, thefirst control section 14a, or thesecond control section 14b. Since the electronic signal that is not required to be transmitted is shielded by thesignal control device 18, the number of electronic signals to be processed by the windingunit 11, the assistingunit 16, thefirst control section 14a, and thesecond control section 14b is reduced. As described above, since thesignal control device 18 carries out a check on the transmitted electronic signal, theautomatic winder 100 according to the present embodiment prevents unnecessary electronic signals from stagnating on the communication path, thus avoiding the windingunit 11, the assistingunit 16, and the like from entering the standby state. - According to such a configuration, in the
automatic winder 100 according to one embodiment of the present invention, the delay in the electronic signal processing can be reduced since thesignal control device 18 selects whether to transmit or shield an electronic signal in accordance with the transmitting destination of the electronic signal. Therefore, in theautomatic winder 100, the operation efficiency of the windingunit 11, the assistingunit 16, and the like can be improved. - Furthermore, in the
automatic winder 100, the delay in the electronic signal processing transmitted between the groups G1 and G2 can be reduced since thesignal control device 18 selects whether to transmit or shield an electronic signal in accordance with the transmitting destination of the electronic signal between the group connected with the first communication path G1 and the group connected with the second communication path G2. Accordingly, the operation efficiency of the windingunit 11, the assistingunit 16, and the like can be improved. - Here, a flow of an electronic signal processing in the
automatic winder 100 will be specifically described assuming a case in which the package P is in a fully-wound state in one windingunit 11. Note that a control mode described below is merely an example, and the present invention is not limited thereto. - An electronic signal indicating that the package P is in a fully-wound state is transmitted from the winding
unit 11 to the doffingdevice 13. The electronic signal transmitted from the windingunit 11 is transmitted to the doffingdevice 13 via thefirst communication path 17a and thethird communication path 17c. Thus, when transmitting the electronic signal (doffing request signal) from the group connected with the first communication path G1 to the group connected with the second communication path G2, thesignal control device 18 transmits the electronic signal. - During the operation of the package conveyor, the electronic signal indicating to prohibit the doffing operation is transmitted from the
second control section 14b to the doffingdevice 13. The electronic signal indicating to prohibit the doffing operation controls the operation of the assistingunit 16 such as the doffingdevice 13 and the package conveyor. The assistingunit 16 such as the doffingdevice 13 and the package conveyor is data linked to each other, and hence the capacity of the electronic signal transmitted from thesecond control section 14b to the assistingunit 16 becomes large. Therefore, if the electronic signal transmitted from thesecond control section 14b to the assistingunit 16 is transmitted to the group G1 without being shielded by thesignal control device 18, the transmission and reception of the electronic signals in the group G1 is greatly delayed. In this regard, in theautomatic winder 100 according to the present embodiment, the delay of the electronic signal in the group G1 can be reduced since thesignal control device 18 shields the transmission of the electronic signal to the group G1 when transmitting the electronic signal from the group G2 only to the relevant group G2. - Thus, when transmitting the electronic signal from the group connected with the second communication path G2 only to the relevant group G2, the
signal control device 18 shields the electronic signal. That is, thesignal control device 18 prevents the electronic signal from being transmitted into the group connected with the first communication path G1, so that reduction of the delay in the electronic signal processing is achieved. Meanwhile, in the group G1, the electronic signal of the current operation state or the like can be transmitted from the windingunit 11 to thefirst control section 14a, for example. - The electronic signal indicating that the collection of the package P and the attachment of the next winding bobbin B2 are completed is transmitted from the doffing
device 13 to the windingunit 11. The electronic signal transmitted from the doffingdevice 13 is transmitted to the windingunit 11 via thesecond communication path 17b and thethird communication path 17c. Thus, when transmitting the electronic signal from the group connected with the second communication path G2 to the group connected with the first communication path G1, thesignal control device 18 transmits the electronic signal. - The electronic signal related to the winding condition of the winding
unit 11 is transmitted from thefirst control section 14a to the windingunit 11. The electronic signal transmitted from thefirst control section 14a is transmitted to the windingunit 11 via thefirst communication path 17a. Thus, when transmitting the electronic signal from the group connected with the first communication path G1 only to the relevant group G1, thesignal control device 18 shields the electronic signal. That is, thesignal control device 18 prevents the electronic signal from being transmitted to the group connected with the second communication path G2, so that reduction of the delay in the electronic signal processing is achieved. Meanwhile, in the group G2, the electronic signal indicating to prohibit the doffing device can be transmitted from thesecond control section 14b to the doffingdevice 13, for example. The electronic signal related to the winding condition of the windingunit 11 includes items related to winding speed, yarn count, winding tension, winding amount of winding package, and package weight. - The electronic signal transmitted from the group G1 only to the relevant group G1 includes information related to the winding state transmitted from the winding
unit 11 to thefirst control section 14a. This information includes package diameter, winding speed, occurrence situation of yarn cut, detection situation of yarn defect, and the like. The information is sequentially transmitted from the windingunit 11 to thefirst control section 14a during the operation of the windingunit 11. - According to such a configuration, the
signal control device 18 transmits the electronic signal when transmitting the electronic signal from the group connected with the first communication path G1 to the group connected with the second communication path G2, and shields the electronic signal when transmitting the electronic signal from the group connected with the first communication path G1 only to the relevant group G1. Thus, the delay in the electronic signal processing transmitted between the groups G1 and G2 can be reduced. Accordingly, the operation efficiency of the windingunit 11, the assistingunit 16, and the like can be improved. - Moreover, the
signal control device 18 transmits the electronic signal when transmitting the electronic signal from the group connected with the second communication path G2 to the group connected with the first communication path G1, and shields the electronic signal when transmitting the electronic signal from the group connected with the second communication path G2 only to the relevant group G2. Thus, the delay in the electronic signal processing transmitted between the groups G1 and G2 can be reduced. Accordingly, the operation efficiency of the windingunit 11, the assistingunit 16, and the like can be improved. - A spinning
machine 200, which is a yarn winding machine, according to one embodiment of the present invention will be described below. -
FIG. 3 is a view illustrating an overall configuration of the spinningmachine 200. The spinningmachine 200 is mainly configured by a plurality of windingunits 21, ayarn joining device 22, a doffingdevice 23, a package conveyor (not illustrated), and acontrol device 24. - The winding
unit 21 drafts the supplied sliver and twists the drafted sliver to produce the yarn Y. The windingunit 21 winds the yarn Y by rotating a winding bobbin B3, and forms a package P on the winding bobbin B3. In this manner, the windingunit 21 produces the yarn Y from the sliver, and also forms the package P by winding the yarn Y. - Each winding
unit 21 is connected to a windingunit control section 21a (seeFIG. 4 ). The windingunit control section 21a includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a communication port. The ROM stores a control program for controlling the operation of the windingunit 21. The CPU executes the control program stored in the ROM to enable the winding of the yarn Y to be appropriately carried out. In the spinningmachine 200, the plurality of windingunits 21 is connected to one windingunit control section 21a. The windingunit control section 21a is thus configured to be able to control the operation of the plurality of windingunits 21. - The communication port provided in the winding
unit control section 21a is connected to thecontrol device 24 and an assistingunit 26 and is configured to be able to transmit and receive electronic signals (seeFIG. 4 ). Thecontrol device 24 thus can collectively carry out the operation control and the information management of the plurality of windingunits 21 arranged in the spinningmachine 200. - The
yarn joining device 22 moves along arail 22a installed in the arranging direction of each windingunit 21. Theyarn joining device 22 joins the yarn ends of the cut yarn Y of the windingunit 21. In this manner, theyarn joining device 22 joins the cut yarn Y so that the windingunit 21 can continuously form the package P. - The doffing
device 23 moves along arail 23a extended in the arranging direction of the windingunits 21. The doffingdevice 23 detaches the fully-wound package P from the windingunit 21 and attaches the next winding bobbin B3. The doffingdevice 23 thus can collect the fully-wound package P and enable the windingunit 21 to continuously form the package P. - The package conveyor is arranged in the arranging direction of the winding
units 21, and is intermittently operated so as to be able to transport the fully-wound package P detached by the doffingdevice 23 to the end in the longitudinal direction of the spinningmachine 200. - The
yarn joining device 22, the doffingdevice 23, and the package conveyor are devices that assist the windingunit 21 to form the package P. Therefore, in the present embodiment, theyarn joining device 22, the doffingdevice 23, and the package conveyor are defined as the assistingunit 26 of the windingunit 21. However, the assistingunit 26 merely needs to be a device for directly or indirectly assisting the windingunit 21 to form the package P, and is not limited to theyarn joining device 22, the doffingdevice 23, and the package conveyor. - Each assisting
unit 26 includes an assistingunit control section 26a (seeFIG. 4 ). Similarly to the windingunit control section 21a, the assistingunit control section 26a includes a CPU, a ROM, a RAM, and a communication port. The ROM stores a control program for controlling each component of the assisting unit 26 (yarn joining device 22 or the like) . The CPU executes the control program stored in the ROM to enable the yarn joining operation, the doffing operation, and the like to be appropriately carried out. - The communication port of the assisting
unit control section 26a is connected to thecontrol device 24 and the assistingunit 26, thus enabling the transmission and reception of electronic signals (seeFIG. 4 ). Thecontrol device 24 thus can collectively carry out the operation control and the information management of the plurality of assistingunits 26 arranged in the spinningmachine 200. - The
control device 24 is configured by afirst control section 24a and asecond control section 24b (seeFIG. 4 ). Thefirst control section 24a and thesecond control section 24b are connected to the windingunit 21 or the assistingunit 26 through a communication path 27 (seeFIG. 4 ). Similarly to the windingunit control section 21a, thefirst control section 24a and thesecond control section 24b respectively includes a CPU, a ROM, a RAM, and a communication port. - The communication ports of the
first control section 24a and thesecond control section 24b are connected to the communication port of the windingunit control section 21a and the communication port of the assistingunit control section 26a, respectively, through the communication path 27 (seeFIG. 4 ). According to such a configuration, thecontrol device 24 receives the electronic signals of the operation state and the like from the respective windingunit control section 21a and the respective assistingunit control section 26a, and thus can grasp the operation state of the windingunit 21 and the assistingunit 26. Thecontrol device 24 can transmit the electronic signals of the operation condition and the like to the respective windingunit control section 21a and the respective assistingunit control section 26a, and thus can set the operation state of the windingunit 21 and the assistingunit 26. - The
first control section 24a has an information collecting function of receiving the electronic signals from the windingunit 21 and the assistingunit 26 to grasp the operation state, and a setting function of transmitting the electronic signal to the windingunit 21 and the assistingunit 26 to set the operation state. On the other hand, thesecond control section 24b, has a control function of receiving the electronic signal from the windingunit 21 and the assistingunit 26 to carry out the information processing, and to transmit the electronic signal to the windingunit 21 and the assistingunit 26 to smoothly form the package P. However, the main functions of thefirst control section 24a and thesecond control section 24b are not limited thereto. - The electronic signal (operation condition or the like) transmitted to the winding
unit 21 includes, for example, winding speed, yarn count, winding tension, package winding amount, and package weight. The electronic signal (operation state or the like) transmitted from the windingunit 21 includes, for example, package diameter, winding speed, yarn cut occurrence situation, and alarm information. The set value transmitted to the windingunit 21 can be transmitted while individually specifying each windingunit 21, or may be collectively transmitted with respect to all the windingunits 11. -
FIG. 4 is a view illustrating thecommunication path 27 of the spinningmachine 200. Thecommunication path 27 is mainly sectionalized into afirst communication path 27a, asecond communication path 27b, and athird communication path 27c. - The
first communication path 27a connects the windingunit 21 and thefirst control section 24a so as to be communicable with each other. Thus, thefirst communication path 27a can transmit an electronic signal transmitted from the windingunit 21 to thefirst control section 24a. Thefirst communication path 27a can also transmit an electronic signal transmitted from thefirst control section 24a to the windingunit 21. - The
second communication path 27b connects the assistingunit 26 and thesecond control section 24b so as to be communicable with each other. Thus, thesecond communication path 27b can transmit an electronic signal transmitted from the assistingunit 26 to thesecond control section 24b. Thesecond communication path 27b can also transmit an electronic signal transmitted from thesecond control section 24b to the assistingunit 26. - The
third communication path 27c connects a group connected by the first communication path G1 and a group connected by the second communication path G2 so as to be communicable with each other. Thus, thethird communication path 27c can transmit an electronic signal transmitted from the windingunit 21 to thesecond control section 24b. Thethird communication path 27c can also transmit an electronic signal transmitted from thesecond control section 24b to the windingunit 21. Furthermore, thethird communication path 27c can transmit an electronic signal transmitted from the assistingunit 26 to thefirst control section 24a. Thethird communication path 27c can also transmit an electronic signal transmitted from thefirst control section 24a to the assistingunit 26. That is, by connecting the group G1 configured by the windingunit 21 and thefirst control section 24a and the group G2 configured by the assistingunit 26 and thesecond control section 24b, thethird communication path 27c enables the windingunit 21, the assistingunit 26, thefirst control section 24a, and thesecond control section 24b to be able to transmit electronic signals with each other. - The spinning
machine 200 further includes asignal control device 28 on thethird communication path 27c. That is, thesignal control device 28 is arranged between the group connected by the first communication path G1 and the group connected by the second communication path G2. - The
signal control device 28 is an information communication device adapted to select whether to transmit or shield an electronic signal in accordance with a transmitting destination of the electronic signal.
