DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized control system for a spinning machine in which a large number of spinning machines are managed by a centralized control device. The present invention relates to a method of transferring data from a spinning machine to a centralized management device, which can grasp the real-time operation state of the machine.

[0002]

2. Description of the Related Art A spinning machine is provided with a large number of weights for processing roving or sliver into yarn. In order to grasp the running state of the yarn at each weight and the broken state of the yarn, the spinning machine detects the current operation state (hereinafter referred to as status) of each weight in real time. Further, the spinning machine creates operation data including the number of times of change obtained by detecting the time change of the status and the accumulated time. If the operation data and the operation efficiency of each weight based on the operation data are calculated, it is possible to determine whether the weight is good or defective from the result.

[0003] In a factory or the like equipped with a large number of spinning machines, it has been considered to provide a centralized control device for centralized control of these spinning machines. A centralized control device is connected to each spinning machine via a communication line, and the operation data is collected from each spinning machine by polling, for example. In a centralized management device, if the display screen shows a list of various statistical values based on data collected from each spinning machine, graphs and analysis results, and a printer outputs reports at regular intervals, a large number of Can be managed efficiently.

If a centralized control device is provided, when there is a defect in the spindle or the spinning machine, it is possible to display the fact or to display a work instruction for removing the defect. Therefore, the worker who monitors the spinning machine does not need to always monitor the spinning machine at all times, and only needs to look at the centralized control device in usual times. Then, except for patrol monitoring of the row of the spinning machine at regular intervals, it is only necessary to go to the spindle or the spinning machine only when a work instruction is displayed.

[0005]

By the way, since the spinning machine grasps the status of each spindle in real time, if this information is transmitted to the central control unit together with the operation data, the status of each spindle in the central control unit is determined. List display is also possible. Since the status includes a signal indicating that the weight stops until the operator performs the return work, such as an abnormal warning signal, the list display of all weight status allows the worker at the position of the central control device to display It is possible to discover this and rush to the site or instruct workers near the site.

However, it takes a lot of time for the centralized control device to collect status data and operation data from all spinning machines. This is mainly because the information amount of the operation data is large. In other words, the operation data of each spindle is diversified and has a large amount of information to be useful for management. In addition, since one spinning machine has many spindles, one spinning machine transmits at one time. The amount of information to be done is very large. In addition, 1
There are 30 spinning machines under one centralized control device,
It takes, for example, 10 minutes for the central control device to finish collecting data from the spinning machine.

[0007] To spend 10 minutes for data collection means that the status displayed on the display screen of the central control device is the status 10 minutes before the worst. Therefore, when relying on the centralized control device, the weight must be 1 before the operator notices.
It happens that it is stopped for 0 minutes and waiting for return. This is a problem because it lowers the operation efficiency of the spinning machine.

Further, the stop weight is actually in the operating state (spinning).
May occur, the screen display may remain stopped for 10 minutes.

[0009] Therefore, an object of the present invention is to solve the above-mentioned problems, and not only to collect the operation results of the spinning machines at predetermined time intervals, but also to realize a real-time status of all the spinning machines from the spinning machine to the centralized control device. It is to provide a data transfer method .

[0010]

In order to achieve the above-mentioned object, the present invention provides a large number of spinning machines, and the spinning machine uses status data and time data of status data for each spindle.
Operation data is created, and the central control device operates the spinning machine.
Collect status data from each spinning machine during
Operation data is collected during non-operation of a computer or the like.

[0011]

With the above arrangement, the central control device constantly collects status data from each spinning machine. Since the data transfer of only the status data can be performed in a relatively short time, the central control device can display the real-time status of all the spinning machines. Therefore, it is possible to promptly take a measure for the abnormality warning.

On the other hand, since the operation data is created by totalizing the status data over time, it is sufficient to collect the operation data at regular intervals.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIG. 1, the centralized control system for a spinning machine includes a large number of spinning machines 1 and one centralized control device 2. The spinning machine 1 has a large number of weights arranged in a row and the analyzing device 3.

More specifically, as shown in FIG. 3, the spinning machine 1 has a large number of spinning units (weights) 31 arranged in a straight line, and an analysis device 3 is provided at one end thereof. In the figure, the weight is omitted on the right side of the alternate long and short dash line. Each of the weights 31 includes a draft device 33 for extending a roving or sliver 32 and a spinning nozzle 34 for processing the roving or sliver 32 into a yarn 38 and feeding the yarn 38. A delivery roller 35 is provided below the spinning nozzle 34, Slack tube 36,
A yarn clearer (slab catcher) 37 is provided in order. The yarn clearer 37 detects the quality of the yarn and functions to cut the yarn if the yarn is defective (slab). A winding device 40 for winding the yarn 38 around the bobbin 39 is provided below the yarn clearer 37. Each weight 31 has an abnormality warning member 41 that operates according to an abnormality warning signal described later.
And a full lamp 42 indicating that the bobbin 39 is full. The abnormality warning member 41 is a member having a red protrusion, and is called a red flag 41 because the protrusion protrudes from the surface of the weight 31 during operation.

The spinning machine 1 is provided with a work carriage 43 which faces the space where the yarn 38 should travel between the yarn clearer 37 and the winding device 40 from behind and reciprocates along the row of the weights 31. . The work bogie 43 has the full bobbin 39 removed and sent out of the system, and a new empty paper tube is taken up by the winding device 4.
Doffing device 44 for supplying the piecing device 0 and a piecing device 4 for piecing
5 and a control device 46 for performing these controls are mounted. The work vehicle 43 stops at the position of the thread 31 or the full weight 31 during the reciprocating movement and performs necessary operations.

A signal indicating that the yarn has been cut by the yarn clearer 37, an abnormality warning signal accompanied by a red flag 41, a signal synchronized with the full lamp 42, and the like are sent from the weight 31 to the analyzer 3. That is, each of the weights 31 is running full (yarn running), finding a slab and cutting the yarn (slab cutting), cutting the yarn for a cause other than the slab (cutting the red flag), and becoming full. (Full), and the results of these detections are constantly transmitted to the analyzer 3. Here, the red flag break indicates that the yarn has broken without any defect (slab). This is because there is an abnormality such as yarn clogging. It is a state that should not be done.

The analyzing device 3 stores the above four states (status) in two bits of a yarn running signal indicating that the winding machine is rotating and an abnormal warning signal indicating that the weight is waiting for processing. To create coded status data. That is, the relationship between the status data and the status is as shown in Table 1. In Table 1, the yarn running signal is marked as FW, and the abnormality warning signal is marked with a red flag.

[0019]

[Table 1]

The analysis device 3 creates operation data which is made up of time data of status data. The operation data shows the time during which the yarn has run normally, the time when the yarn has stopped due to the slab break, the time when the yarn has stopped due to the red flag running out, the time when the process has been waited for the full load, the number of red flag slab breaks, and the red flag. It is composed of the number of times the vessel has been filled and the number of times the vessel has been fully filled. The breakdown of the operation data and the data length are shown in Table 2. Since the status data in Table 1 and the operation data in Table 2 are data for each spindle, the analyzer always creates a data amount obtained by multiplying the data by the number of spindles.

[0021]

[Table 2]

The central control device 2 for centrally controlling these spinning machines comprises a personal computer having a display device 5. The central control device 2 is connected to the analysis device 3 of each spinning machine 1 by a common communication line 4. The central control device 2 sequentially polls the analyzing device 3 of each spinning machine 1, requests transmission of status data, and repeats polling as soon as the polling is completed. Further, the central management device 2 requests transmission of operation data at regular intervals. The analysis device 3 of each spinning machine can transmit the status data S or the operation data G created so far in response to these requests.

Next, the operation of the embodiment will be described.

As shown in FIG. 1, the central control device 2 constantly polls the analyzing device 3 of the spinning machine 1, and the analyzing device 3 of the spinning machine 1 transmits status data S in response thereto. Since the status data is stored in one byte per spindle, the number of bytes per spinning machine is also about several tens of bytes. Therefore, the time for collecting the status data of, for example, 30 spinning machines 1 is within one minute.

The central control device 2 can grasp the real-time status of all the spinning machines within one minute. The central management device 2 displays the status of all the weights on the display device 5 as shown in FIG. 2, the status of all spindles is represented by a code and displayed in a list, and the machine numbers of the spinning machines are 1, 2,.
, And the horizontal axis indicates the weight number of each machine frame as 1, 2,..., 40, 41, 42,. The status of the weight of the spinning machine is indicated by a symbol in a grid where the vertical axis and the horizontal axis intersect. However, the status of the normal operation state is blank-displayed. Since most of the weights are in a normal operation state, the sign appears on the screen only for weights in a stopped state or in an abnormal state. The codes are, for example, red flag = 3, full = 2. Status codes that require special attention, such as a red flag, are displayed in red on the screen. On the screen, a window 6 marked "instantaneous efficiency" indicating that this screen display is a status display of all spindles is opened. In FIG. 2, since the status code 3 = red flag of the 42nd weight of the 7th machine stand, it can be understood that the thread is broken due to a cause other than the slab and is waiting for the operator's processing.

As described above, when the status of all the weights is displayed in a list on the display device 5 of the central control device 2, the operator can instantly know the current operating state of all the weights. Therefore, if there is a weight of the red flag, it is possible to immediately rush to the site or instruct a worker near the site. In addition, when the full vessel is displayed, the operator can return automatically under normal circumstances, so the worker does not need to move, but if the full vessel does not disappear even after a lapse of time, danger of doffing is assumed. So
After all I will go to the site.

On the other hand, the central control device polls the spinning machine for operation data instead of polling status data at the shift end or at the end of operation of the day, for example.
The spinning machine transmits operation data in response to this. Although transmission of the operation data requires a longer time than transmission of the status data, monitoring of the status of the entire spindle does not cause any inconvenience.

[0028]

The present invention exhibits the following excellent effects.

(1) Since the real-time status can be displayed on the centralized management device, the operator can replace this with patrol monitoring by monitoring this display, thereby saving labor.

(2) Since the transmission of status data required to be real-time and the transmission of operation data as a result of temporal aggregation are separately separated, the time for collecting operation data is as follows: A more suitable time can be selected and set without considering the transmission speed of the status data.
