DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery sewing management system for an embroidery sewing machine, and more particularly, to a method for simplifying sewing operations without requiring special equipment, thereby preventing erroneous operations. The present invention relates to an embroidery sewing management system capable of collecting production management information such as a sewing history of an embroidery sewing machine.

[0002]

2. Description of the Related Art Conventionally, in a sewing machine, an abnormal state during a sewing operation is cumulatively stored, and the accumulated history data is used as data for production management. For example, in Japanese Patent No. 2800556, a history of abnormal conditions such as thread breakage that has occurred in the past is cumulatively stored in a storage means, and in a later sewing operation, an operator can immediately take appropriate processing. A sewing machine capable of performing tuning of sewing operation of the sewing machine, prediction of future occurrence of abnormality, and the like is described.

When sewing a predetermined embroidery pattern,
2. Description of the Related Art It has been practiced to transfer predetermined sewing data via a network or the like to obtain it. For example, Japanese Patent Application Laid-Open No. 4-332
In Japanese Patent No. 592, the embroidery sewing machine is treated in the same manner as a computer terminal, and a predetermined sewing data title name is selected from the sewing data list on the sewing machine side, and a data transfer command is issued to the computer to perform a predetermined sewing. An automatic sewing system capable of data transfer capable of obtaining data is described.

[0004]

However, in the conventional sewing machine disclosed in Japanese Patent No. 2800556, the accumulated history data of the abnormal state is stored in an external storage device such as an EEPROM in the sewing machine main body or a hard disk drive. Stay. In this case, there is no problem in performing routine analysis of abnormal data using the sewing machine alone, but a large amount of data is required in order to perform high-precision analysis, and the EEPROM cannot cope with the problem. In addition, there is a situation that a precision device such as a hard disk drive is not preferable for installation on a sewing machine with vibration. Furthermore, if the user wants to analyze the data from various perspectives while taking various conditions into account, routine processing on the sewing machine itself is not sufficient. The operator has to go to the sewing machine directly and collect the data every time, and if a large-scale facility such as a sewing factory is provided, a heavy burden is imposed on the manager, which is a problem. In addition, in the case of a single sewing machine as in the prior art, the daily sewing plan and the sewing work of each embroidery pattern are stored by the operator based on a report, and the necessary sewing data is stored at any time while checking the sewing procedure. It is common to select a recording medium such as a floppy disk or the like, and it is difficult to avoid a work error due to a mistake in reading a form or a floppy disk or the like, and there is a problem that sewing workability is poor.

Further, the above-mentioned prior art disclosed in Japanese Patent Laid-Open No.
The use of the automatic sewing system capable of data transfer in Japanese Patent No. 2592 discloses a method of collecting history data, sewing procedures, and delivering sewing data via a network. However, in order to connect all sewing machines via the network, This is a problem because a large investment burden is imposed, and a great deal of labor is required for maintaining and managing the network even after the completion of the facilities. In addition, forcing all operators to perform a series of sewing procedures and selection of sewing data on a network is difficult even though the operability of a computer system for constructing the network is improved. An erroneous operation may cause the network system to stop, and there are many problems in smooth operation including retraining of the operator.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the prior art, and a series of sewing procedures and selection of sewing data when sewing an embroidery pattern can be easily and reliably performed.

Further, the production management information during the sewing operation can be stored in the removable recording medium in association with the information on the sewing operation by the data storage means without any special operation by the operator, and this is sequentially stored. Therefore, the storage amount is not limited as in the case of storing in the storage device in the sewing machine main body, and the production management information is collected in a state classified for each sewing operation. As described above, a large amount of production management information is appropriately accumulated, and diversified information analysis can be performed with high accuracy, and the productivity of production management in sewing operations can be improved. Further, when the production management information during the sewing operation is stored in a recording medium storing a series of information necessary for the sewing operation, the data can be securely stored in a leak-free state by the data storage means. Even if you do not have a transfer facility, production management information is reliably collected on the recording medium returned after work without omission, and the work burden of the administrator collecting the production management information directly from the sewing machine is reduced. Therefore, it is possible to efficiently perform the analysis work of the production management information of the manager.
Therefore, there is no need for an investment burden or a human burden for building a network environment, and there is no need for a management burden or an operation burden after the construction, which greatly contributes to effective utilization of management resources.

After storing the management information in the second storage means, the management information is written to the recording medium by the writing means.

[0015] Thus, the difference in operation speed between the reading and writing of information from the recording medium and the sewing operation of the sewing machine is absorbed, and the sewing schedule information recorded on the recording medium and the sewing required based on the information. While reading the data, a series of sewing operations can be smoothly performed, and the production management information during the sewing operation can be written on the recording medium without any trouble, thereby further improving the sewing workability. The production management information stored in the second storage means is
Finally, the writing means can store the sewing schedule information and the sewing data on which the sewing operation has been performed in the recording medium storing the sewing data, and can sequentially store the information. It is not necessary to rely on the limited storage capacity, and the production management information is collected in a state classified for each sewing operation. As described above, it is possible to accumulate a large amount of information as appropriate and perform multi-dimensional analysis with high accuracy, thereby improving the productivity of production management in sewing work. Furthermore, a series of procedures for reading out the information necessary for the sewing operation and performing the sewing operation and simultaneously storing the production management information can be performed smoothly by absorbing the difference between the speed of the recording medium and the sewing operation of the sewing machine. Even if you do not have a data transfer facility such as the above, production management information is surely collected without omission in the recording medium returned after work, and the administrator can directly collect the production management information from the sewing machine. There is no work load, and the manager can efficiently analyze the production management information.

It is a flowchart which shows a display.

First, the sewing process and the writing of log data during sewing will be described with reference to FIGS. FIG. 5 is a flowchart of a procedure management program showing the processing of the sewing operation by the embroidery sewing management system according to the present embodiment. When the sewing operation by the sewing management system is started in step (hereinafter abbreviated as S) 1,
The contents of the schedule table execution flag 73C in the RAM 73 are confirmed. Then, when there is the sewing schedule table 41A currently being executed (S1: YES), the execution of the scheduled sewing is started from the continuation of the sewing schedule table 41A which is being executed (S6). If there is no sewing schedule table 41A currently being executed (S1: NO), the sewing schedule table 41 is acquired from the floppy disk 31 mounted on the floppy disk drive device 30 (S2), and the sewing schedule to be executed from the list is acquired. The table 41A is selected (S3) and stored in the buffer 73A in the RAM 73 (S4). At the start of sewing, both the counter S indicating the sewing step being executed and the counter P indicating the number of sewings in each sewing step are initialized to 1 and the RAM 7 is initialized.
After setting in the memory 73E of the third sewing machine (S5), the routine of the scheduled sewing execution is called (S6). Upon completion of the sewing operation by this routine, the sewing operation by the sewing management system is completed (S7).

FIG. 6 shows a routine of the scheduled sewing execution called in S6. First, the counter S of the memory 73E
If the value is not the end of the sewing step number in the sewing schedule table 41A (the stage before N in FIG. 4) and the sewing is not completed (S8: NO), the sewing step of the sewing schedule table 41A corresponding to the counter S is performed. Is read from the floppy disk 31 mounted on the floppy disk drive 30 (S9). Prior to sewing the embroidery pattern, the position of the work cloth is adjusted in a trace mode or the like so that sewing can be performed within the range of the work cloth fixed to the cloth support frame 16c (S10, S11: N).
O), sewing is started after the adjustment is completed (S11: YE)
S). In the sewing operation, production management information such as history data of the sewing operation is written as log data in a log writing file (see FIG. 4) together with the actual sewing operation (S).
12). When the sewing operation is completed and the sewing step is completed,
The counter S is incremented by one (S13), and the process returns to S8. If the counter S value has not reached the end of the sewing step number in the sewing schedule table 41A (S8: NO), the processing after S9 is repeated, and if the counter S value has reached the last number (S8: YE
S) Assuming that the sewing schedule in the sewing schedule table 41A has been completed, the routine of the scheduled sewing execution is terminated (S14), and the sewing operation by the sewing management system is terminated (S7).

FIG. 7 is a flowchart of the log management program showing the log data writing process. At the start of sewing, the log write file name in the sewing step of the sewing schedule table 41A is obtained from the floppy disk 31 (S15), a log write file of the same name is created in the log write file buffer 73B, and the sewing start time is written (S15). S16). When the counter P value indicating the number of sewn pieces does not exceed the number of sewn pieces in each sewing step of the sewing schedule table 41A (S17: NO), the operation state of the sewing machine M is monitored (S18). When the sewing machine M has stopped (S18: Y
ES), the stop time is written to the log writing file (S
19) If the stop is due to the occurrence of an error (S2)
0: YES) The stop due to the occurrence of the error and the contents of the error are written to the log write file (S21). After the writing is completed or when no error has occurred (S20: NO), this state is maintained until a sewing restart instruction is issued (S22: NO), and the sewing restart instruction is issued (S22: Y).
ES) Write the sewing restart time to the log write file (S
23) Return to S18. In the state where the operation of the sewing machine M is not stopped (S18: NO), the monitoring is continued until the sewing operation during the sewing in the sewing step is completed (S24: NO). After the increase (S24: YES, S25), the process returns to S17.
If it is confirmed in S17 that the counter P value has reached the planned number of sewings (S17: YES), the time at which the sewing work in this sewing step has been completed is written in the log writing file, and then the log writing file buffer is written. From 73B, the log writing file is stored in the floppy disk 31, and the log data writing process is terminated (S26, S27).

From the log writing file obtained here,
Multilateral analysis can be performed depending on how data is processed. For example, the sewing start time written in S16 and S
The total work time is obtained from the sewing end time written in 26, and the stop time is obtained from the sewing machine stop time written in S19 and the sewing restart time written in S23. Then, the operating rate of the sewing machine M is calculated from the two, and
It is also possible to analyze the error occurrence frequency, stop rate, etc. by classifying each error content written in. Further, the sewing step in the sewing schedule table 41A can be specified from the sewing machine stop time, the content of the error can be associated with the sewing step, and a sewing pattern or the like in which a specific error easily occurs can be found.

From the above, the sewing schedule table 4 necessary for the sewing operation
1A and the sewing data are stored in the floppy disk 31 and supplied to each operator, so that the sewing operation can be performed in accordance with the instruction of the sewing data, and the operator can check the work form or select the sewing data. Sewing work mistakes are eliminated, and sewing workability can be improved. Since the log writing file during the sewing operation is also stored on the same floppy disk 31, if the floppy disk 31 is collected at the end of the sewing operation, each sewing schedule table 41A
The log write files classified for each can be collected, and the work load of management information collection can be greatly reduced. The log writing file created by the above processing is classified as production management information such as sewing history data corresponding to each sewing step in the sewing schedule table 41A, and is stored as a separate file for each sewing step as a floppy disk. The start time, stop time, restart time, error content, etc. of the sewing machine M in the sewing operation at each sewing step are recorded, and the operating time, the operating rate, the stop cause, and the like of the sewing machine M are recorded. Basic data for analyzing production management information such as details of an error, its occurrence frequency, and the relationship between sewing data and the occurrence of an error can be stored in the floppy disk 31 in a state of high use value.

0). If the counter R value is smaller than Q (S40:
NO), the log data is totaled for the log write file numbered with the counter R value (S41). Here, each log writing file is created as a file name obtained by adding a sewing date to a sewing data name for each piece of sewing data in each sewing step, and is stored in one sewing schedule table 41A or a sewing schedule. List 41 of different sewing schedules in list 41
Since a large number of the same sewing data may exist in 1A, among the log writing files numbered for each sewing data, the log writing file having the same number as the counter R value is usually a plurality of files. In step S41, all log write files belonging to the same number are counted. When the counting is completed, the value of the counter R is increased by one (S42), and the process returns to S40. When the value of the counter R becomes larger than the total number Q of types of log writing files (S40: YES), all the totaling results are collectively displayed (S4).

Basic data for analyzing the production management information can be stored in the floppy disk 31 in a classified state having a high use value.

Further, using a log data totaling / analyzing computer system (not shown), sewing is performed based on the processing of the log data totaling routine (1) of FIG. 8 and the log data totaling routine (2) of FIG. Since log data can be totaled for each schedule or for each piece of sewing data, the administrator simply collects the floppy disk 31 after the sewing operation is completed, and the log data is sorted in each sewing schedule. It is not necessary to build a network to collect and manage log data, and it is possible to collect and manage log data in a simple manner without capital investment and management burden for that .
The collected log data is accumulated sequentially, so that sufficient data required for analysis can be accumulated, and highly accurate and diversified analysis can be performed by a simple data collection management method. It can be carried out.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention. For example, in the present embodiment, a method in which the selection (S3) of the sewing schedule table 41A from the sewing schedule table list 41 is left to the operator has been described as an example, but the selection method is not limited to this. By setting the sewing schedule to be worked by the administrator and storing it on the floppy disk 31, it is also possible to make a setting that does not require selection by the operator. In this embodiment, the floppy disk 31 is used as the recording medium. However, the present invention is not limited to this, and any removable recording medium such as MD, MO, and magnetic tape may be used. Further, even in a network environment, a configuration having a data structure capable of handling the sewing schedule table, the sewing data, and the production management information in a unified manner while associating them with each other can be adopted.

As described above, according to the embroidery sewing management system according to the first aspect, the production management information during the sewing operation can be stored in the removable recording medium in association with the information on the sewing operation, and this can be sequentially stored. Since it can be accumulated, it can be further collected in a state classified for each sewing operation, so that a large amount of production management information can be accumulated for each sewing operation, each sewing machine for embroidery sewing, etc. Information analysis can be performed, and the productivity of production management in the sewing operation can be improved. In addition, since the production management information as a result of the sewing operation is also stored in the recording medium storing a series of information necessary for the sewing operation, the production management information can be collected by collecting the recording medium, and a data transfer facility such as a network is provided. Even in a sewing facility that has not been used, there is no need for the administrator to directly go to the sewing machine and collect production management information, and the administrator can efficiently perform the production management work. Further, since a series of operation information and sewing data necessary for the sewing operation are collectively stored in the recording medium,
There is no need for the operator to select necessary sewing data from a large number of recording media at any time while checking the form, and there is no sewing operation error due to a form confirmation error or a recording medium selection error. Sewing workability can be improved. In addition, it is not necessary to maintain a network environment in order to collectively obtain a series of work information and sewing data necessary for sewing work and efficiently collect production management information such as sewing history data. Therefore, there is no need for investment burden and human burden, and there is no need for management burden and operation burden after the construction, and it is important to contribute to effective utilization of management resources.

According to the embroidery sewing management system according to the second aspect of the present invention, a series of sewing operations does not involve the judgment or operation of the operator, eliminating the sewing operation error due to the operator's misjudgment and improving the sewing workability. Can be done. Further, the production management information during the sewing operation can be stored in the removable recording medium in association with the information on the sewing operation by the data storage means without any special operation by the operator. Since a large amount of production management information is appropriately collected, diversified information analysis can be performed with high accuracy, and the productivity of production management in sewing operations can be improved. Further, when the production management information during the sewing operation is stored in a recording medium storing a series of information necessary for the sewing operation, the data can be securely stored in a leak-free state by the data storage means. Even if it does not have a transfer facility, the production management information is reliably collected on the recording medium returned after the operation without omission, and the manager can efficiently analyze the production management information. Therefore, there is no need for an investment burden or a human burden for constructing the network environment, and there is no need for a management burden or an operation burden after the construction.

According to the embroidery sewing management system according to the third aspect, the difference in operation speed between the reading and writing of information from the recording medium and the sewing operation of the sewing machine is absorbed, and the sewing schedule recorded on the recording medium is absorbed. While reading the information and the sewing data, a series of sewing operations can be smoothly performed, and the production management information can be written to the recording medium without any trouble, so that the sewing workability can be further improved. The production management information stored in the second storage means is
Eventually, the writing means can store in the recording medium storing the sewing schedule information and the sewing data on which the sewing operation has been performed, and since the information is collected in a state classified for each sewing operation, a large amount of information is collected. Can be accumulated as appropriate, and diversified analysis can be performed with high accuracy, and the productivity of production management in the sewing operation can be improved. Furthermore, the sewing machine reads out necessary information and performs sewing work. At the same time, a series of procedures for storing production management information can be performed smoothly by absorbing the difference between the speed of the recording medium and the sewing work of the sewing machine. Even without a transfer facility, the production management information is reliably collected without any omission in the recording medium, so that the manager can efficiently analyze the production management information. Therefore, there is no need for an investment burden or a human burden for constructing the network environment, and there is no need for a management burden or an operation burden after the construction.

According to the embroidery sewing management system according to the fourth aspect, the production management information during the sewing operation can be associated with the information relating to the sewing operation, uniformly recorded in the storage means, and sequentially stored. In addition, there is no need to be limited to a routine process using a storage device in the sewing machine main body having a limited storage amount. Further, production management information can be collected in a state of being classified for each sewing operation. As described above, since a large amount of production management information is accumulated for each sewing operation or each embroidery sewing machine, highly accurate and diversified information analysis can be performed, thereby improving the productivity of the production management in the sewing operation. it can. In addition, since the production management information is also stored in a storage unit that stores a series of information necessary for sewing work in a unified manner in association with each other, a worker selects necessary sewing data at any time while checking the form. Since no trouble is required, sewing work errors due to confirmation mistakes and selection mistakes are eliminated, and sewing workability can be improved.
