Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management apparatus for a spinning machine, and more particularly to a production management apparatus capable of calculating an accurate production amount of a plurality of spinning machines arranged in parallel.

[0002]

2. Description of the Related Art Conventionally, many spinning machines are installed in parallel in a spinning factory. Each spinning machine base is equipped with a display device (shift counter) for displaying the yarn production amount of each spinning machine base.

This production amount is displayed based on the rotation amount of the front roller provided on the spinning machine base. Usually, spinning factories employ a three-shift work system. The shift counter is provided with three integrating units corresponding to the shift work, and the corresponding integrating units count the rotation amount of the front roller during the shift work. These accumulators are selected by switching the shift changeover switch equipped on each machine base. That is, the worker operates the integrating unit corresponding to each shift work by operating the shift changeover switch at the start time of the shift work, and causes the shift counter to display the production amount in the shift work. That is, the production amount displayed on the shift counter is switched for each shift work, and the worker can confirm the production amount at the shift work at that time by visually recognizing the display on the shift counter. .

[0004]

However, conventionally, at the start time of each shift work, one worker turns around a number of spinning machine bases to perform a switching operation of the shift changeover switch, so that the first machine is operated. There is a gap in the switching time between the machine and the last machine. As a result, the calculated value of the production amount displayed on the display device of each spinning frame always contains an error for each spinning frame. When a plurality of spinning machine bases are operated under the same spinning conditions, the production amount of the spinning machine bases within a predetermined same time is important as data for comparing the performance of each machine. However, in the past, since the display data of the shift counter contained an error, it was difficult to compare the performance between the spinning machine bases based on the production amount displayed on the display device of each spinning machine base. .

The present invention has been made to solve the above problems, and an object thereof is to provide a production management device for a spinning machine, which can obtain an accurate production amount within a predetermined time of a spinning machine stand. Especially.

[0006]

In order to solve the above problems, the invention according to claim 1 provides a production counter provided in a spinning machine base and having a plurality of storage areas for storing the production, and a spinning machine. time counting means provided in the machine base, provided spinning machine, the seek current time based on the timer means, the storage area of the when the current time becomes the preset switching time live production rate counter Switching means and switching knob
Of the production counter by the switching command signal
The gist of the invention is to have a control device having both means for switching the storage area .

According to a second aspect of the present invention, in the first aspect of the present invention, the control device is connected to a time correction device via a communication means, and a correction signal is output from the time correction device. The gist of the invention is to have a correction means for correcting the present time based on the correction signal.

[0008]

Therefore, according to the first aspect of the invention, the production counter provided in the spinning machine stand stores the production quantity in the storage area during operation of the spinning machine stand. At this time, the control device obtains the present time based on the time measuring means,
When the current time reaches a predetermined switching time,
The storage area of the production counter for storing the production amount is switched.

According to the second aspect of the invention, the time correction device outputs a correction signal to each control device via the communication means when a predetermined time is reached, for example. Then, the correction means provided in the control device corrects the present time based on the correction signal.

For example, in a factory with a three-shift working system, by setting the switching time for each replacement time, the three switching times are input to the CPU 6, Stored in the memory 8 for use. That is, in a factory with a three shift work system consisting of the first shift work W1 to the third shift work W3, each shift work W1
As the switching time between W3 to W3, each start time of each shift work W1 to W3 is input to the CPU 6 and stored in the work memory 8. At this time, the same switching time is input to the CPU 6 for each spinning frame 1 and stored in the working memory 8.

The CPU 6 calculates the present time based on the time measured by the timer 6a, and the present time is calculated by each of the shift work W1 to W3.

That is, in the production counter C,
In the first to third storage areas M1 to M3 of the first set, the production amount from the switching time is sequentially added and stored for each unit time based on the switching time of each shift work W1 to W3 stored in advance. It Second to fourth storage areas M4 to M6
On the basis of the first to third switching command signals output from the CPU 6 based on the switching knob 4a and the like, the production amounts from the time when the switching command signal is output are sequentially added and stored for each unit time.

At this time, in the first set, when the CPU 6 determines that the switching time has been reached according to the time counting by the timer 6a, the production amount for each unit time after the switching time is sequentially added, and the added production is performed. The production amount signal indicating the amount is sequentially output to the storage area corresponding to the switching time. At this time, the CPU 6 erases (resets) the stored contents (production amount) of the storage area to which the production amount signal should be output,
The production amount signal is output and stored in the storage area corresponding to the production amount sequentially added after the switching time. Then, after the input of the production amount signal is stopped, the production amount at the time of the stop is stored in the storage area.

That is, in the first group, the first shift work W
When the switching time at which 1 is started comes, the CPU 6 outputs the production amount signal to the first storage area M1 to store the production amounts sequentially added after the switching time. Second
When the changeover time when the shift work W2 of
U6 outputs the production amount signal to the second storage area M2 to store the production amount sequentially added after the switching time. At the switching time at which the third shift work W3 is started, the CPU 6 outputs a production amount signal to the third storage area M3 to store the production amounts sequentially added after the switching time. In other words, the CPU 6 uses each shift work W
At the switching time of 1 to W3, the storage area for storing the production amount is switched.

Further, in the second group, when the switching command signal is output, the CPU 6 sequentially adds the production amounts for each unit time after the output of the switching command signal, and shows the added production amount. The production amount signal is sequentially output to the storage area corresponding to the switching command signal. At this time, the CPU 6 erases (resets) the stored contents (production amount) of the storage area to which the production amount signal should be output, then outputs the production amount signal, and is sequentially added from the time when the switching command signal is output. The stored production amount is stored in the corresponding storage area. And
After the input of the production amount signal is stopped, the production amount at the time of the stop is stored in the storage area.

That is, in the second set, when the first switching command signal is output, the CPU 6 outputs the production amount signal to the fourth storage area M4, and sequentially from the time when the first switching command is output. The added production volume is stored. When the second switching command signal is output, the CPU 6 outputs a production amount signal to the fifth storage area M5 to store the production amount sequentially added from the time when the second switching command is output. Third

The storage area for storing the production amount is switched based on the third switching command signal.

Further, the CPU 6 allows the operator to use the keyboard 5
By operating, the first display command signal or the second display command signal is output from the keyboard 5. That is,
When the first display command signal is output to the CPU 6, the CPU
Reference numeral 6 indicates the production amount in the storage region in which the production amount signal is output from the first to third storage regions of the first set and the production amount sequentially added by the CPU 6 per unit time is stored. Display on the device 3.

When the second display command signal is output to the CPU 6, the CPU 6 outputs a production amount signal from the second to fourth storage areas of the second set and the CPU 6 outputs the output signal every unit time. The display device 3 is caused to display the production amount in the storage area in which the production amount sequentially added to is stored.

Then, each of the first to sixth storage areas M1 to M
6 has a storage capacity for one day, and the contents stored in each of the first to sixth storage areas M1 to M6 are retained in an external storage medium such as a magnetic tape for each day. Further, the contents stored in the working memory 8 can be printed by the printer P1.

Next, the operation and effect of the production control device in the spinning machine configured as described above will be described. First, the worker inputs the switching time, which indicates the start time of each shift work W1 to W3, from each keyboard 5 to each CPU 6 according to the three shift work system in advance, and stores the switching time in the work memory 8. Then, during normal operation, the operator operates the keyboard 5 of each spinning machine base 1 to
The first display command signal is output to the CPU 6.

Then, when the switching time at which the first shift work W1 is started, the CPU 6 calculates the production amount per unit time based on the count number from the pulse counter 9, and outputs the production amount signal to the first storage. Output to area M1. CP
U6 erases the stored contents of the first storage area M1 up to the switching time point, and then sequentially calculates the production amount per unit time from the output point of the first switching command signal,
In the memory area M1. At this time, the storage content of the first storage area M1 is displayed on the display device 3.

From this state, at the switching time at which the second shift work W2 is started, the CPU 6 switches the storage area for outputting the production amount signal from the first storage area M1 to the second storage area M2. The CPU 6 uses the second
No. 2 until the switching time when the shift work W2 is started
After erasing the stored contents of the storage area M2, the storage amount is stored in the second storage area M2 while sequentially adding the production amount for each unit time from the switching time point. In addition, the first storage area M
In 1 is stored the production amount from the switching time of the first shift work W1 to the switching time of the second shift work W2, that is, the production amount in the first shift work W1. At this time, the display displayed on the display device 3 is switched from the display based on the first storage area M1 to the display based on the second storage area M2.
On the display device 3, the production amount stored in the second storage area M2 is displayed.

At the switching time at which the third shift work is started, the CPU 6 switches the storage area for outputting the production amount signal from the second storage area M2 to the third storage area M3. Similarly to the above, the CPU 6 erases the stored contents of the third storage area M3 until the switching time when the third shift work W3 is started, and then stores the data in the third storage area M3 from the switching time. The production amount for each unit time is sequentially added and stored. Further, the production amount in the second shift work W2 is stored in the second storage area M2. At this time, the display displayed on the display device 3 is the second storage area M2.
Is switched to the display based on the third storage area M3, and the display device 3 displays the production amount stored in the third storage area M3.

Next, for example, in each shift work W1 to W3, since the start time of the first shift work W1 is delayed for some reason, the switching time of each shift work W1 to W3 is desired to be delayed from the normal time. There are cases.

At this time, the operator selects the first shift work W1 with the switching knob 4a while the switch 4b provided on each spinning machine base 1 is turned on. Then, the first switching command signal is output to the CPU 6 of each spinning frame 1. Then, the operator operates the keyboard 5 to output a second display command signal to the CPU 6 in order to display the production amount for each switching time selected by the switching knob 4a on the display device 3. When the CPU 6 inputs the second switching command signal, for example, the output of the production amount signal to the storage area based on each switching time is continued, and in addition, the production amount signal is also output to the fourth storage area M4. To do. CPU6
After erasing the stored contents of the fourth storage area M4 up to the output time point of the first switching command signal, the production in the fourth storage area M4 per unit time from the output time point of the first switching command signal The amount is stored while being sequentially added. At this time, the production amount stored in the fourth storage area M4 is sequentially displayed on the display device 3.

At the switching time when the second shift work W2 is started, the second shift work W is switched by the switching knob 4a while the switch 4b of each spinning frame 1 is turned on.
Select 2. Then, the second switching command signal is output to the CPU 6. Then, the CPU 6 switches the storage area for outputting the production amount signal from the fourth storage area M4 to the fifth storage area M5. Then, the CPU 6 erases the stored contents of the fifth storage area M5 up to the output time point of the switching command signal, and then produces the fifth storage area M5 at every unit time from the output time point of the second switching command signal. The amount is stored while being sequentially added. Further, in the fourth storage area, the production amount from the output of the first switching command signal to the time of outputting the second switching command signal, that is, the first shift work W1.
The internal production volume is stored. At this time, the display displayed on the display device 3 is switched from the display based on the fourth storage region M4 to the display based on the fifth storage region M5, and the display device 3 stores the display in the fifth storage region M5. The production volume is displayed in sequence.

From this state, when the switching time at which the third shift work W3 is started comes, the third shift work W3 is selected by the switching knob 4a while the switch 4b of each spinning frame 1 is turned on. . Then, the third switching command signal is output to the CPU 6. Then, the CPU 6 changes the storage area for outputting the production amount signal from the fifth storage area M5 to the sixth storage area M5.
Memory area M6. Then, the CPU 6 erases the stored contents of the sixth storage area M6 up to the output time point of the third switching command signal, and then outputs the unit time from the output time point of the third switching command signal to the sixth storage area M6. The production amount for each is sequentially added and stored. The production amount in the second shift work W2 is stored in the fifth storage area. At this time, the display displayed on the display device 3 is switched from the display based on the fifth storage region M5 to the display based on the sixth storage region M6, and the display device 3 stores the display in the sixth storage region M6. The production volume is displayed in sequence.

When one day has passed, the data stored in the first to sixth storage areas of the work memory 8 are stored in the external storage medium or the like, and the printer P1 is also used as necessary.
Is printed by and stored as production control data. Then, the data of the next day is overwritten in the first to sixth storage areas of the work memory 8.

As described above in detail, according to the first embodiment,
The CPU 6 of the control device 2 provided in each spinning frame 1 calculates the current time according to the timer 6a. At this time, the CPU 6 can automatically switch the storage area for storing the production amount of the spinning machine base 1 calculated by the CPU 6 all at once at the switching time of each shift work W1 to W3. Further, the CPU 6 can switch the storage area and simultaneously switch the display of the display device 3 at each switching time. For this reason, it is possible to prevent a shift in the switching time for each spinning machine base 1 that occurs when one worker turns the multiple spinning machine bases 1 one by one to switch the display of the display device 3. , While calculating accurate production volume,
It can be displayed on the display device 3. Then, the performance between the spinning machine bases 1 can be determined based on the production amount displayed on the display device 3.

Therefore, the display device 3 can accurately display the production amount of each machine stand 1 in each of the shift work W1 to W3. Therefore, it is possible to accurately compare the production amount of each shift work W1 to W3 and the production amount of each machine stand 1.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG.
It will be described with reference to FIG. The configurations of the spinning frame and the control device provided in the spinning frame in the second embodiment are basically the same as those in the first embodiment, and the same members are designated by the same reference numerals. And the description is omitted.

As shown in FIG. 5, the control device 2 provided in each of the spinning machine frames 1 arranged in parallel is a time correction device via a local area network (LAN) L as a communication means. It is connected to the host computer 11.

A display device 11a is connected to the host computer 11 so as to display various kinds of information such as the production amount on each spinning machine base 1. A keyboard 12 is provided in the host computer 11.
That is, the host computer 11 outputs various command signals to the control device 2 based on input signals from the keyboard 12.

Next, the electrical construction of the production control device in the spinning machine thus constructed will be described. Figure 4,
As shown in FIG. 5, the host computer 11 includes a central processing unit (hereinafter referred to as CPU) 13 and a program memory 14 including a read-only memory (ROM) storing a control program. Further, the host computer 11 is provided with a working memory 15 which is a readable and rewritable memory (RAM) for temporarily storing the calculation processing result in the CPU 13. The CPU 13 is provided with a timer 13a. CPU 13 is timer 13a
The present time is sequentially calculated according to the clocking of.

Further, when the time calculated by the timer 13a reaches a predetermined time, the CPU 13
A correction signal for correcting the time calculated based on the timer 6a provided in the control device 2 is periodically output to all the control devices 2 simultaneously via the local area network L. This predetermined time is input to the CPU 13 by the operator via the keyboard 12, for example, and is stored in the work memory 15. At this time, the worker inputs various data such as a period, the number of times, and what time through the keyboard 12 as data indicating a predetermined time, and these various data are stored in the working memory 15. For example, the operator inputs each data indicating “one day” as the period, “one time” as the number of times, and “0:00:00 am” as what time through the keyboard 12 and stores it in the work memory 15. As a result, the correction signal is output once a day at 00:00:00 on the local area network L. At this time, various data indicating the predetermined time is recorded in the correction signal.

Further, the CPU 13 outputs various command signals for controlling production of the spinning frame 1 to all the control devices 2 based on various operations of the keyboard 12. Furthermore, a printer P2 is connected to the CPU 13 as an external printing device.

When the correction signal is output from the host computer 11, the CPU 6 of the control device 2 operates on the basis of the data indicating the predetermined time recorded in the correction signal.
The current time calculated by 6 is corrected.
That is, the CPU 6 corrects the present time so that the time when the correction signal is output becomes a predetermined time. At this time, since the current time calculated by each CPU 6 of each spinning frame 1 is corrected so that the time when the correction signal is output becomes a predetermined time, the current time is calculated when the correction signal is output. The current time calculated by each CPU 6 is the same. Therefore, even if the present time that each CPU 6 sequentially calculates with the passage of time is deviated,
The deviation between the spinning machine bases 1 is reduced.

The contents stored in the working memory 8 are, as shown in FIG. 5, a local area network L.
It is transferred to the host computer 11 via the printer and can be printed by the printer P2 of the host computer 11. That is, in the working memory 15 of the host computer 11, storage areas corresponding to the respective storage areas M1 to M6 of the working memory 8 are formed for each spinning frame 1.
Then, the production amount stored in the desired storage area of the desired spinning frame 1 can be displayed on the display device 11a provided in the host computer 11. The printer P2 of the host computer 11 prints the production amount stored in each storage area of the work memory 15 of the host computer 11 or the production amount stored in the desired storage area of the work memory 15. It is possible.

Next, the operation and effect of the production control device in the spinning machine configured as described above will be described. First, the operator is the keyboard 12 of the host computer 11.
Is operated by the CPU to output a correction signal for correcting the current time calculated by each control device 2.
13 and stores it in the working memory 15. At this time, the CPU 6 provided in each spinning machine base 1 uses the timer 6a.
The current time is calculated based on the clock.

In this state, the host computer 1
1 outputs a correction signal to the CPUs 6 of all the control devices 2 via the local area network L at a predetermined time. Then, each CPU 6 calculates the current time as the time when the correction signal is output is the predetermined time. That is, the current time calculated by the CPU 6 is corrected by outputting the correction signal so that the output time becomes a predetermined time. Therefore, at the time when the correction signal is output, the current time calculated by each CPU 6 of each spinning frame 1 is the same. Since this is performed regularly, even if the current time sequentially calculated by each CPU 6 with time elapses, the deviation between the spinning machine bases 1 is reduced.

Further, the CPU 1 of the host computer 11
Data 3 stored in the work memory 8 from the control device 2 is input via the local area network L and stored in the work memory 15 of the host computer 11.

When one day has passed, the data stored in the first and second storage areas of the work memory 8 are output to the host computer 11 and stored in the work memory 15. Further, it is printed by the printer P2 as necessary and stored as production control data. Then, the data of the next day is overwritten in the first and second storage areas of the work memory 8.

As described in detail above, according to the second embodiment,
At a predetermined time, the host computer 11 sends the correction signal to all CPs via the local area network L.
Output to U6. At this time, the CPU 6 can collectively set the current time at the time when the correction signal is output to the predetermined time. Therefore, between the spinning machine bases 1, it is possible to reduce the deviation of the current time that the CPUs 6 sequentially calculate with the lapse of time. Therefore, a more accurate production amount can be calculated and displayed on the display device 3. At this time, the host computer 1
The same display as that of the display device 3 can be displayed on the display device 11a of No. 1 as well.

Further, according to the correction signal from the host computer 11, each C at the time when the correction signal is output.
In order to correct all the current times calculated by the PU 6 so as to be the same, it is possible to omit the time and labor required for the operator to rotate the many spinning machine bases 1 one by one to correct the time lag.
