Description

Maintenance sequence adjustment system for textile machinery

Technical Field

The invention relates to a maintenance sequence adjustment system of a textile machine.

Background

There is a system having a textile machine that generates a fiber assemblage. For example, patent literature (japanese patent application laid-open No. 1-183530) describes the following system: the yarn winding machine includes a plurality of spinning machines for producing yarns, a textile machine for producing yarns as a fiber assembly, and a plurality of automatic winding machines for winding yarns.

In the system including the textile machine that generates the fiber aggregate as described above, maintenance such as oiling is required for each textile machine. For example, when maintenance is performed on a textile machine in a subsequent step in a step of producing a fiber aggregate, it is considered that the operation of the textile machine in a previous step is affected by the operating state of the textile machine in the subsequent step.

The preceding step is not limited to a step immediately before and immediately after the subsequent step (preceding step), and includes a step two or more preceding steps with respect to the subsequent step. Therefore, when maintenance is performed on a plurality of textile machines in the subsequent step, it is desired to perform maintenance on the textile machines in the subsequent step while suppressing influence on the operation of the textile machines in the previous step.

Disclosure of Invention

Therefore, an object of the present invention is to provide a maintenance sequence adjustment system for a textile machine, which can adjust and present a sequence of maintenance for a plurality of textile machines in a subsequent process according to an operating state of the textile machine in a previous process.

The maintenance sequence adjustment system for a textile machine of the present invention comprises: 1 or more first textile machines for subjecting a first fiber aggregate to a first treatment; a plurality of second textile machines to which the second fiber aggregate subjected to the first processing by the first textile machine is supplied and which generate a third fiber aggregate by subjecting the supplied second fiber aggregate to a second processing; an operation information acquisition unit that acquires operation information indicating an operation state of the first textile machine; a sequence setting unit that determines a maintenance sequence for performing maintenance on the plurality of second textile machines based on a preset sequence, and adjusts the determined maintenance sequence based on the operation information acquired by the operation information acquisition unit; and a presentation unit that presents the maintenance order adjusted by the order setting unit.

In the maintenance sequence adjustment system for the textile machine, the maintenance sequence of the plurality of second textile machines in the subsequent process can be adjusted and presented according to the operation state of the first textile machine in the previous process. Therefore, the maintenance operator can perform maintenance of the second textile machine while suppressing an influence on the operating state of the first textile machine by performing maintenance of the second textile machine according to the presented maintenance procedure. The first textile machine is not limited to the textile machine used in the immediately preceding step of the second textile machine, and may be a textile machine used in two preceding steps or a step preceding the second textile machine.

The order setting unit may repeat, at a predetermined cycle: the method includes a step of determining a maintenance sequence of the second textile machine based on a preset sequence, and a step of adjusting the determined maintenance sequence based on the operation information. Thus, the order setting unit can repeat the determination and adjustment of the maintenance order.

The order setting unit may adjust the maintenance order based on the operation information at a cycle shorter than a cycle at which the maintenance order is determined based on a preset order. Thus, even if the operating state of the spinning machine constantly changes, the order setting unit can adjust the maintenance order in accordance with the change in the operating state.

The maintenance order adjustment system for a textile machine may include a plurality of first textile machines, and the order setting unit may be configured to adjust the maintenance order so as to preferentially perform maintenance on a second textile machine corresponding to a first textile machine having a supply waiting time equal to or longer than a predetermined time, when calculating, based on the operation information, a supply waiting time, which is a time until the first textile machine can supply the second fiber aggregate to the second textile machine next, and adjusting the maintenance order, for 1 first textile machine, and the order setting unit may be configured to calculate, based on the operation information, the supply waiting time, and to adjust the maintenance order. For example, when the supply waiting time is long, even if the second textile machine is stopped and maintenance is performed during this time, the influence on the operation of the first textile machine in the previous step is small. Therefore, by adjusting the maintenance order so as to preferentially perform maintenance on the second textile machine corresponding to the first textile machine whose supply waiting time is equal to or longer than the predetermined time, it is possible to suppress influence on the operation of the first textile machine in the previous step even if the second textile machine is stopped and maintenance is performed.

The order setting unit may further calculate a margin time during which the second textile machine can be stopped for performing maintenance of the second textile machine, based on the supply waiting time, and the presentation unit may further present the margin time calculated by the order setting unit. In this case, the maintenance operator can grasp the time margin for performing the maintenance.

When the maintenance contents to be performed on the second textile machine are a plurality of maintenance contents, the order setting unit may adjust the maintenance order so that the maintenance contents that can be completed within the supply waiting time are preferentially performed. Thus, even if maintenance of the second textile machine is performed, influence on the operation of the first textile machine is suppressed.

The order setting unit may further adjust the maintenance order based on a current position of the maintenance operator. This enables the maintenance operator to perform the maintenance operation efficiently.

The presenting unit may also present maintenance contents of maintenance performed on the second textile machine. In this case, the maintenance worker can grasp the maintenance contents and the margin time. Thus, the maintenance operator can determine whether or not maintenance can be performed within a margin time.

The presentation unit may sort the presented presentation items according to a predetermined rule based on an instruction from a maintenance operator. Thus, the maintenance sequence adjustment system of the textile machine can perform various support for judgment of a maintenance operator and maintenance operation.

The first textile machine may be a spinning machine that generates a yarn from the first fiber aggregate and winds the generated yarn to generate a yarn supplying bobbin as the second fiber aggregate, and the second textile machine may be an automatic spinning machine that winds the yarn from the yarn supplying bobbin to generate a package as the third fiber aggregate. For example, in a system including a spinning machine and an automatic winder, the spinning machine may be a speed control stage of the throughput of the entire system. In this case, it is not preferable to cause the maintenance work of the automatic winder to affect the operation of the spinning machine (stop the process) from the viewpoint of productivity. Therefore, by determining the maintenance procedure of the automatic winder based on the operating state of the spinning machine, it is possible to suppress a reduction in the throughput of the entire system.

The spinning machine and the automatic winder may be provided in plural numbers, and 1 automatic winder may be associated with 1 spinning machine as a supply destination of the yarn supplying bobbin.

According to the present invention, the maintenance sequence for a plurality of textile machines in the subsequent process can be adjusted and presented according to the operating state of the textile machine in the previous process.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description thereof is omitted.

The maintenance sequence adjustment system according to the present embodiment is a system for adjusting the maintenance sequence of a textile machine that processes a fiber aggregate. The fiber aggregate is a fiber product or a fiber material such as Yarn (Yarn), Sliver (Sliver), roving (Rover), Lap (Lap), Web (Web), woven fabric, and knitted fabric. The fiber assembly may be a roving bobbin around which a roving is wound, a yarn supplying bobbin around which a yarn is wound, or a package. In the present embodiment, as a process for a fiber assembly, a case will be described in which a yarn is produced from a roving, the produced yarn is wound to form (produce) a yarn supplying bobbin, and the yarn wound by the yarn supplying bobbin is rewound to form (produce) a package. As shown in fig. 1, a maintenance sequence adjustment system (maintenance sequence adjustment system for textile machines) 1 includes: a plurality of spinning machines (first textile machine) 2, a plurality of automatic spinning machines (second textile machine) 3, and a management device 5. In the present embodiment, the spinning machine 2 and the automatic winder 3 are provided with 3 units, respectively. The number of the spinning frames 2 and the automatic winder 3 is not limited to 3.

The spinning machine 2 performs a process of producing a yarn. The spinning machine 2 includes a spun yarn control device 22 and a plurality of spun yarn units 21. The spinning unit 21 performs a process (first process) of producing a yarn from the roving and winding the produced yarn to form a yarn supplying bobbin (second fiber aggregate) B. The roving bobbin (first fiber assembly) around which the roving is wound in the roving frame (not shown) is supplied to the spinning unit 21. The spun yarn control device 22 controls the operation of the plurality of spun yarn units 21.

The spinning machine 2 is configured as a so-called collective doffing type (Simultaneous doffing type). That is, the spinning machine 2 stores a plurality of empty bobbins transferred from the winder unit 31 by the bobbin transfer device 33 in advance, and places the empty bobbins on the respective spinning units 21 at the same time to start winding of the yarn at the same time. When the yarn supplying bobbin B is formed after the winding of the yarn is completed in each of the spun yarn units 21, the spun yarn machine 2 simultaneously doffs (doffing) all the yarn supplying bobbins B. Then, the spinning machine 2 extracts the stored empty bobbins from the tray 33a and simultaneously places them on the respective spinning units 21 again, and instead, simultaneously places the doffed yarn supplying bobbins B on the tray 33 a.

The automatic winder 3 is supplied with a yarn supplying bobbin B from the spinning machine 2, and performs a process (second process) of winding a yarn from the supplied yarn supplying bobbin B to form a package (third fiber assembly) P. The automatic winder 3 includes: a winder control device 32, a bobbin transfer device 33, and a plurality of winder units 31. The bobbin transfer device 33 transfers the yarn supplying bobbin B placed on the tray 33a to each winder unit 31.

The winder unit 31 unwinds the yarn from the yarn supplying bobbin B to form a package P around which the yarn of a predetermined length is wound. The winder control device 32 controls the operation of the winder units 31 and the operation of the bobbin transfer device 33.

For convenience of explanation, the

spinning machines

2A, 2B, and 2C are 3 spinning machines 2. Similarly, 3 automatic winders 3 are set as an automatic winder 3A, an automatic winder 3B, and an automatic winder 3C, respectively. In the present embodiment, the bobbin transfer device 33 receives the yarn supplying bobbin B from one spinning machine 2 and transfers the yarn supplying bobbin B. That is, 1 automatic winder 3 is used as a supply destination of the yarn supplying bobbin B for 1 spinning machine 2, and the spinning machine 2 and the automatic winder 3 are associated with each other.

Specifically, the bobbin transfer device 33 of the automatic winder 3A receives the yarn supplying bobbin B from the spinning frame 2A and transfers the yarn supplying bobbin B to the winder unit 31 of the automatic winder 3A. The bobbin transfer device 33 of the automatic winder 3B receives the yarn supplying bobbin B from the spinning frame 2B and transfers the yarn supplying bobbin B to the winder unit 31 of the automatic winder 3B. The bobbin transfer device 33 of the automatic winder 3C receives the yarn supplying bobbin B from the spinning frame 2C and transfers the yarn supplying bobbin B to the winder unit 31 of the automatic winder 3C.

The management device 5 is a device that integrally manages the spinning machine 2 and the automatic winder 3. The management device 5 includes a display unit (presentation unit) 51 and a management control unit 52. The management control Unit 52 is an electronic control Unit having, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), and a communication Unit. The management control unit 52 loads a program stored in the ROM into the RAM, and executes various processes by using a numerical value or the like stored in the EEPROM and executing the program by the CPU.

The management control unit 52 can communicate with the spun yarn control devices 22 provided in the respective spinning frames 2 and the winder control devices 32 provided in the respective automatic winders 3 via the communication cables L. The management control unit 52 determines a maintenance procedure when performing maintenance on the plurality of automatic winders 3. The display unit 51 is a device capable of displaying information such as a display. The display unit 51 displays (presents) the maintenance procedure adjusted by the management control unit 52.

The spinning frames 2A to 2C and the automatic spinning frames 3A to 3C are assigned respective body numbers for identifying the respective frames. The management device 5 can identify the spinning frames 2A to 2C and the automatic winders 3A to 3C using the body numbers when integrally managing the spinning frames 2 and the automatic winders 3.

Next, the details of the maintenance procedure presentation process performed by the management apparatus 5 will be described. As shown in fig. 2, the spun yarn control device 22 of the spinning machine 2 includes an operation information transmitting unit 22 a. The operation information transmitting unit 22a transmits, to the management device 5 via the communication cable L, operation information indicating the operation state of the spinning machine 2 including the operation information transmitting unit 22 a.

Here, the operation information includes a time period until the spinning machine 2 subsequently doffs the yarn supplying bobbin B, that is, a doffing waiting time. The operation information may include information on whether the spinning machine 2 (the spinning unit 21) is in operation or stopped. The information during the stop may include a state in which the operation is stopped by waiting for the replacement of the bobbin, and a state in which the operation is stopped due to a failure. The operation information may include offline information indicating that communication with the spinning machine 2 is not possible. Examples of the inability to communicate with the spinning machine 2 include a case where communication is not possible due to power-off of the spinning machine 2, and a case where communication is not possible due to a problem occurring in the communication cable L or the like. Further, as an example of the operation information, the operation efficiency of the spinning machine 2, the yarn production amount, the time for stopping due to a failure, and the like may be included.

The management control unit 52 functionally includes an operation information acquisition unit 52a, a maintenance cycle storage unit 52b, a sequence setting unit 52c, and a display control unit 52 d. The operation information acquiring unit 52a acquires the operation information transmitted from the operation information transmitting unit 22a of the spinning machine 2 via the communication cable L.

The maintenance cycle storage unit 52b stores the maintenance cycle of the automatic winder 3. The maintenance cycle is a cycle in which maintenance is performed on the plurality of automatic winders 3A to 3C according to a predetermined cycle set in advance. For example, the maintenance cycle is set in advance based on the operation time of the automatic winder 3 and the like. The maintenance period is set for each maintenance content. Specifically, the maintenance contents include oiling, component replacement, and cleaning of each part of the winder unit 31, oiling, component replacement, and cleaning of each part of the bobbin transfer device 33, and the like. The maintenance cycle and the contents are preset by, for example, a manufacturer of the automatic winder 3.

The order setting unit 52C determines a maintenance period (time to perform maintenance) when performing maintenance on the plurality of automatic winders 3A to 3C based on the maintenance cycle stored in the maintenance cycle storage unit 52 b. Here, the order setting unit 52c can set, as the maintenance period, a timing that is a predetermined period before the timing at which the maintenance period arrives so as not to exceed the preset maintenance period. Hereinafter, maintenance performed based on a maintenance cycle is referred to as "regular maintenance".

The order setting unit 52C determines a maintenance order for performing the regular maintenance on the plurality of automatic winders 3A to 3C based on a preset order. For example, when oiling the automatic winders 3A to 3C is performed as regular maintenance, it is necessary to determine a maintenance order so that a maintenance operator can sequentially perform operations on the respective automatic winders 3A to 3C. Therefore, the order setting unit 52c determines the maintenance order based on the preset order. Here, the order setting unit 52c can determine the maintenance order as a preset order using the body numbers set for the automatic winders 3A to 3B, for example. The order setting unit 52c may determine the maintenance order according to another preset order, as the preset order, in addition to the machine body number.

Here, the maintenance of the automatic winder 3 includes not only regular maintenance but also irregular maintenance. For example, the irregular maintenance includes maintenance such as oiling, cleaning, or part replacement performed on the automatic winder 3, which is specific due to individual differences of the automatic winder 3, or the like. The information of the irregular maintenance may be inputted to the management device 5 by an operator of the automatic winder 3 or the like, or may be automatically determined by the winder control device 32 or the like to determine whether the irregular maintenance is necessary and inputted to the management device 5. The information for the irregular maintenance of the input management device 5 includes: a period during which the non-regular maintenance is performed, information on a part to be maintained, and maintenance contents.

The order setting unit 52c adds the irregular maintenance to the maintenance order of the regular maintenance based on the period during which the irregular maintenance is performed. Thus, the maintenance order setting unit 52c determines the maintenance order including the regular maintenance and the irregular maintenance.

After the maintenance procedure is determined, the procedure setting unit 52c adjusts the determined maintenance procedure based on the operation information acquired by the operation information acquiring unit 52 a. Specifically, the order setting unit 52c calculates a supply waiting time, which is a time until each of the spinning frames 2 can supply the yarn supplying bobbin B to each of the automatic spoolers 3 next, for each of the spinning frames 2 based on the operation information. The order setting unit 52c can calculate the supply waiting time based on at least one of the time required for the spinning machine 2 to wind the yarn supplying bobbin B, the time required for the spinning machine 2 to stop due to a failure, and the time included in the operation information. Further, the order setting unit 52c may calculate the supply waiting time by using information other than the doffing waiting time, the time required for the spinning machine 2 to wind the yarn supplying bobbin B, and the time when the spinning machine 2 stops due to a failure, as long as the information included in the operation information is used.

When adjusting the maintenance procedure, first, the procedure setting unit 52C selects the spinning machine 2 having the calculated supply waiting time equal to or longer than a predetermined time among the spinning machines 2A to 2C. The order setting unit 52c adjusts the maintenance order so as to preferentially perform maintenance of the automatic winder 3 in which the correspondence relationship as the supply destination of the yarn supplying bobbin B is established for the selected spinning machine 2.

The maintenance is performed prior to other maintenance. That is, the maintenance order of the maintenance to be prioritized is advanced (the order is advanced), or the maintenance order of the maintenance other than the maintenance to be prioritized is adjusted to be subsequent to the maintenance order of the maintenance to be prioritized.

For example, the maintenance procedure determined by the procedure setting unit 52C is the procedure of the automatic winder 3A, the automatic winder 3B, and the automatic winder 3C. The spinning machine 2B is set to have a supply waiting time equal to or longer than a predetermined time, and the

spinning machines

2A and 2C are set to have a supply waiting time shorter than the predetermined time. In this case, since there is time until the yarn supplying bobbin B is supplied from the spinning machine 2B to the automatic winder 3B, the maintenance of the automatic winder 3B is performed during this time, and it is possible to suppress the influence on the operation of the spinning machine 2B. Therefore, the order setting unit 52c adjusts the maintenance order and preferentially performs maintenance of the automatic winder 3B associated with the spinning machine 2B having the supply waiting time equal to or longer than the predetermined time.

In addition, for example, there is a case where a plurality of maintenance contents are simultaneously performed in the maintenance of the automatic winder 3. In this case, the order setting unit 52c may adjust the maintenance order when adjusting the maintenance order of the automatic winder 3 based on the supply waiting time, and prioritize the maintenance contents that can be completed within the supply waiting time.

For example, the supply waiting time of the spinning machine 2B is set to be equal to or longer than a predetermined time. Further, it is assumed that there are a plurality of maintenance contents to be simultaneously performed in the maintenance of the automatic winder 3B. In this case, the order setting unit 52c selects a maintenance content that can be completed within the supply waiting time, from among a plurality of maintenance contents performed on the automatic winder 3B. The order setting unit 52c may advance the maintenance order of the selected maintenance contents to preferentially implement the selected maintenance contents. Thus, by performing maintenance of the automatic winder 3B, it is possible to suppress the influence on the operation of the spinning machine 2B.

For example, the operation information acquiring unit 52a may be able to acquire the operation information of the textile machine (for example, a roving frame) in a step before the spinning frame 2. In this case, the order setting unit 52c may adjust the maintenance order of the automatic winder 3 based on the operation information of the textile machine in the process before the spinning machine 2, instead of the operation state of the spinning machine 2. For example, when the roving frame or the like is stopped for a long time, it can be predicted that the spinning frame 2 is stopped for a predetermined time while the spinning frame 2 is in operation at the present time while waiting for the roving to be supplied. For example, when the spinning machine 2B is expected to stop soon, the order setting unit 52c may delay the maintenance period of the automatic winder 3B (delay the maintenance order) so that the operation of the spinning machine 2B is not stopped by performing the maintenance of the automatic winder 3B. For example, the order setting unit 52c may adjust the maintenance period of the automatic winder 3B so that the maintenance period of the automatic winder 3B overlaps the period in which the spinning machine 2B is stopped, and the period in which the operation of the spinning machine 2B is not stopped by the maintenance of the automatic winder 3B. When the maintenance period of the automatic winder 3 is delayed, the order setting unit 52c sets the period so as not to exceed a preset maintenance cycle.

Further, the order setting unit 52c calculates a margin time during which the automatic winder 3 can be stopped for maintenance based on the supply waiting time included in the operation information. For example, the order setting unit 52c may set the supply waiting time as the margin time, or may set a time obtained by adding a predetermined time to the supply waiting time or a time obtained by subtracting the predetermined time from the supply waiting time as the margin time. The order setting unit 52c may determine the margin time based on the supply waiting time and information other than the supply waiting time. The order setting unit 52c is not limited to using the supply waiting time included in the operation information, and may determine the margin time based on information other than the supply waiting time (for example, information on whether the spinning machine 2 is in operation or stopped).

The order setting unit 52c repeatedly determines the maintenance order of the regular maintenance and the irregular maintenance of the automatic winder 3 and adjusts the maintenance order based on the operating state of the spinning frame 2 at predetermined intervals. The order setting unit 52c may determine the maintenance order of the automatic winder 3 and adjust the maintenance order based on the operating state of the spinning frame 2 at the same cycle, or may determine the maintenance order of the automatic winder 3 and adjust the maintenance order based on the operating state of the spinning frame 2 at different cycles. The operating state of the spinning frame 2 constantly changes. Therefore, the order setting unit 52c may adjust the maintenance order based on the operating state of the spinning machine 2 at a predetermined cycle (for example, within 10 minutes) shorter than the cycle of the determination of the maintenance order of the automatic winder 3.

The order setting unit 52c creates schedule data in which the determined maintenance period, the machine number of the maintenance target, the maintenance order, the maintenance contents, the margin time, and the like are associated with each other. The order setting unit 52c updates the schedule data every time the maintenance order of the automatic winder 3 is adjusted, for example.

The display controller 52d converts the schedule data created by the order setting unit 52c into a predetermined format and displays the schedule data on the display unit 51. The display controller 52d updates the display of the display unit 51 every time the schedule data is updated in the sequence setting unit 52 c. The maintenance operator can grasp the maintenance procedure and the like when performing maintenance on the plurality of automatic winders 3 by observing the display unit 51.

For example, the display controller 52d can convert the schedule data into a calendar display format as in the screen example SC1 shown in fig. 3, and display the converted data on the display 51. Screen example SC1 of fig. 3 shows schedule data of 3 months at a time point of 3 months and 3 days, for example. In this example, 6 maintenance jobs to be performed on 3/12/20 XX year, 3/13/3, and the like are shown. In this case, the maintenance operator can grasp how many maintenance processes are required on how many days.

Note that, in the screen example SC1 shown in fig. 3, the maintenance procedure adjusted by the procedure setting unit 52c based on the operating state of the spinning machine 2 is also reflected. The case where the maintenance order adjusted by the order setting unit 52c is reflected is, for example, a case where a predetermined maintenance work originally to be performed on day 3/13 based on the maintenance cycle is changed to day 3/12 based on the operating state of the spinning machine 2.

For example, the display controller 52d can convert the schedule data into a table format as in the case of the screen example SC2 of fig. 4 (a) and the screen example SC3 of fig. 4 (b), and display the converted schedule data on the display 51. An example screen SC2 shown in fig. 4 (a) shows details of maintenance items to be performed on a specific day (here, 3 months and 12 days). An example screen SC3 shown in fig. 4 (b) shows all maintenance items to be performed in month 3. Similarly to the screen example SC1 shown in fig. 3, the screen example SC2 shown in fig. 4 (a) and the screen example SC3 shown in fig. 4 (b) show maintenance items at 3 months and 3 days. These tables include the machine body number, the maintenance position (location), the maintenance contents, the remaining time, and the like of the automatic winder 3 to be operated. The sequence of maintenance operations in the tables of screen examples SC2 and SC3 is adjusted by sequence setting unit 52 c. The maintenance operator can grasp the maintenance procedure of the automatic winder 3 determined based on the operating state of the spinning machine 2 by observing the table.

The display formats of the schedule data shown in such screen examples SC1 to SC3 can be switched by a switching operation by a maintenance operator or the like. The maintenance operator may instruct the switching of the display format using, for example, a touch panel disposed on the display unit 51 in a superimposed manner, or may instruct the switching of the display format using a switch or the like provided in a different portion from the display unit 51. For example, the screen example SC2 shown in fig. 4 (a) may be displayed by touching the portion of day 3, month, and 12 in the calendar display format shown in the screen example SC1 of fig. 3.

When the schedule data shown in fig. 4 a and 4 b is displayed in a tabular format, the display control unit 52d may have a Sort function (Sort function) for sorting the display items (the body number, the location, the maintenance content, and the spare time) according to a predetermined rule. The display can be sorted based on an instruction from a maintenance operator.

For example, the following are the cases: when a plurality of spinning machines 2, automatic winding machines 3, and the like are provided, and a factory in which the spinning machines 2, the automatic winding machines 3, and the like are provided is large, a maintenance worker needs time to move between the machine bodies or between the units. In this case, the maintenance operator can efficiently perform the maintenance work in order from the machine body near the current position by sorting the maintenance items in the order of the machine body numbers, for example. For example, a maintenance worker can perform maintenance work collectively at the same place by sorting maintenance items at the place (maintenance position) of the maintenance work. For example, a maintenance worker can perform maintenance work in order from a work with a long margin time by sorting maintenance items in the margin time. In this way, since the maintenance items sorting function is provided, it is possible to support various kinds of judgment by the maintenance worker and maintenance work.

Here, the remaining time shown in fig. 4 (a) and 4 (b) is the remaining time calculated at the time point of 3 months and 3 days. Therefore, as shown in fig. 4 (a) and 4 (b), if the same equipment is used, the remaining time is the same even if the maintenance day and the maintenance content are different. Similarly, in the maintenance items on the later date than the current date (3 months and 3 days), since the maintenance work may be performed earlier than the adjusted order, the currently calculated remaining time of each machine body is marked together with the maintenance items.

In the example shown in fig. 4 (a) and 4 (b), the bobbin replenishing device is configured to, in addition to "bobbin replenishing device: the irregular maintenance includes "unit number 1: component replacement (splicer) "and the like.

The screen examples shown in fig. 3, 4 (a), and 4 (b) are merely examples, and the display control unit 52d can create various display screen data based on the schedule data and display the display screen data on the display unit 51.

Next, a flow of the maintenance procedure presentation process performed by the management control unit 52 will be described with reference to fig. 5. The processing shown in fig. 5 is repeatedly executed at predetermined cycles as described above. As shown in fig. 5, the order setting unit 52c determines a maintenance order including regular maintenance and irregular maintenance (S101). The order setting unit 52c adjusts the determined maintenance order based on the supply waiting time, which is the time until the spinning machine 2 can supply the yarn supplying bobbin B next (S102). The order setting unit 52c performs the adjustment of the maintenance order when there is a spinning machine 2 whose supply waiting time is equal to or longer than a predetermined time, and does not perform the adjustment of the maintenance order when there is no spinning machine 2 whose supply waiting time is equal to or longer than the predetermined time.

The sequence setting unit 52c calculates a margin time during which the automatic winder 3 can be stopped to perform the maintenance process on the automatic winder 3, based on the supply waiting time (S103). The order setting unit 52c may calculate the margin time for all maintenance operations performed on the automatic winder 3, or may calculate the margin time only for a predetermined maintenance operation.

The order setting unit 52c creates schedule data based on the determined maintenance order, the determined and adjusted maintenance order, and the like (S104). The display control unit 52d converts the schedule data into a predetermined format and displays the schedule data on the display unit 51 (S105).

The present embodiment is configured as described above, and the maintenance sequence adjustment system 1 can adjust and present the maintenance sequence of the automatic winder 3 in the subsequent step in accordance with the operating state of the spinning machine 2 in the previous step. Therefore, the maintenance operator can perform maintenance of the automatic winder 3 while suppressing an influence on the operating state of the spinning machine 2 by performing maintenance of the automatic winder 3 according to the presented maintenance procedure.

The sequence setting unit 52c calculates the supply waiting time, which is the time until the spinning machine 2 can supply the yarn supplying bobbin B next, based on the operation information. The order setting unit 52c adjusts the maintenance order of the automatic winder 3 based on the calculated supply waiting time. For example, when the supply waiting time is long, even if the automatic winder 3 associated with the spinning machine 2 having a long supply waiting time is stopped and maintenance is performed, the influence on the operation of the spinning machine 2 is small. Therefore, by adjusting the maintenance procedure, the maintenance of the automatic winder 3 corresponding to the spinning machine 2 having the supply waiting time equal to or longer than the predetermined time is preferentially performed, and even if the maintenance is performed by stopping the automatic winder 3, the influence on the operation of the spinning machine 2 can be suppressed.

The sequence setting unit 52c calculates a margin time during which the automatic winder 3 can be stopped for maintenance. The display controller 52d also displays the remaining time on the display 51. This enables the maintenance operator to grasp the time remaining for performing the maintenance of the automatic winder 3. For example, when the maintenance is not regular maintenance and the margin time is short, the maintenance can be performed after the maintenance, and the maintenance operator can determine the period of performing the maintenance based on the margin time.

The display controller 52d also displays the maintenance contents on the display 51. In this case, the maintenance worker can grasp the maintenance contents and the margin time. Thus, the maintenance operator can determine whether or not maintenance can be performed within a margin time.

For example, in a system including the spinning machine 2 and the automatic winder 3, the spinning machine 2 may be a speed control stage of the overall system throughput. In this case, it is not preferable to cause the maintenance work of the automatic winder 3 to affect the operation of the spinning machine 2 (stop the operation) from the viewpoint of productivity. Therefore, by determining the maintenance procedure of the automatic winder 3 based on the operating state of the spinning machine 2, it is possible to suppress a reduction in the throughput of the entire system.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, at least some of the above-described embodiments may be arbitrarily combined.

As shown in fig. 1, the spinning machine 2 is associated with 1 spinning machine 2 so that 1 automatic winder 3 is set as a supply destination of the yarn supplying bobbin B. However, the present invention is not limited to this, and the spinning machine 2 may be configured such that two automatic winding

machines

3A and 3B are associated with 1 spinning machine 2A as supply destinations of the yarn supplying bobbin B, as in the maintenance order adjustment system 1A shown in fig. 6. It is to be noted that the automatic winder 3 may be associated with 1

spinning machine

2 or 3 or more automatic winders 3, instead of 1 spinning machine 2. As in the maintenance order adjustment system 1B shown in fig. 7, a plurality of automatic winders 3 may be associated with a plurality of spinning frames 2 so as to be supply destinations to which the yarn supplying bobbins B are supplied by the bobbin transfer device 33.

The yarn supplying bobbin B is not limited to being transferred from the spinning machine 2 to the winder unit 31 of the automatic winder 3 by the bobbin transfer device 33 of the automatic winder 3. The yarn supplying bobbin B may be transferred from the spinning machine 2 to the automatic winder 3 by a device other than the bobbin transfer device 33 or by an operator. In this case as well, 1 automatic winder 3 may be associated with 1 spinning machine 2, a plurality of automatic winders 3 may be associated with 1 spinning machine 2, or a plurality of automatic winders 3 may be associated with a plurality of spinning machines 2. In these cases, as in the embodiment, the maintenance procedure can be determined and adjusted.

The display unit 51 is not limited to being provided in the management device 5. For example, the display unit 51 may be a display unit provided in the spun yarn control device 22 or the winder control device 32. Alternatively, the display unit 51 may be a display screen of a mobile terminal that can be carried by a maintenance worker. Further, the case where the spun yarn control device 22 of the spinning machine 2, the winder control device 32 of the automatic winder 3, and the management control unit 52 of the management device 5 communicate with each other through the communication cable L has been described as an example, but the communication may be performed wirelessly.

When the order setting unit 52c adjusts the maintenance order, for example, the maintenance order may be adjusted based on the current position of the maintenance operator in addition to the operation information of the spinning machine 2, which is the spinning machine in the previous step. The adjustment by the maintenance operator based on the current position may be performed in consideration of adjustment of the movement time when moving to a location where the maintenance operation is to be performed next (adjustment for shortening the movement time) when performing the maintenance operation in order according to the maintenance items. The order setting unit 52c can grasp the current position of the maintenance operator based on, for example, the machine number of the spun yarn control device 22 or the winder control device 32 currently operated by the maintenance operator, or the position information of the portable terminal held by the maintenance operator. Alternatively, the order setting unit 52c may grasp the current position of the maintenance operator based on, for example, the position at which the maintenance operator performs the input operation of the spun yarn control device 22, the winder control device 32, the portable terminal, or the like. In this way, the maintenance order can be adjusted in consideration of the position of the maintenance operator, and the maintenance operator can efficiently perform the maintenance operation.

In the embodiment, the maintenance procedure is presented using the display unit 51, but the maintenance procedure may be presented by outputting a sound from a speaker (presentation unit) instead of the display unit 51.

In the embodiment, the case where the maintenance procedure of the automatic winder 3 is adjusted based on the operating state of the spinning machine 2 is described as an example, but the present invention is not limited to the spinning machine 2 and the automatic winder 3. For example, the present invention can be applied to a drawing frame for forming a string-like sliver in which fibers are aligned, and a spinning frame for spinning the sliver formed by the drawing frame to form a yarn and forming a package P around which the produced yarn is wound. In this case, the maintenance procedure of the spinning frame is adjusted according to the operating state of the drawing frame. The present invention is not limited to application to textile machines used in continuous processes such as a spinning machine and an automatic winder, or a drawing frame and a spinning machine for spinning yarns from drawn yarns. For example, the present invention can be applied to a textile machine used in a discontinuous process such as a roving frame and an automatic winder.

In the above-described embodiment, the case where the maintenance procedure of the textile machine (the spinning machine 2, the automatic winder 3, and the like) that generates the yarn is adjusted is described as an example, but the present invention is not limited to this. The maintenance sequence of the textile machine (carding machine, drawing machine, carding machine, textile machine, knitting machine, etc.) that generates the fiber aggregate (sliver, roving, textile, fabric, etc.) other than the yarn can also be adjusted.
