[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality notification system for a spinning machine or a production line in a spinning factory.

[0002]

2. Description of the Related Art Conventionally, an abnormality in a spinning machine or a production line in a spinning factory has been found by patrols of workers or by an operating state operation monitor. However, if an abnormality is found, a processing instruction is found. Persons give verbal instructions to the person in charge, issue memo instructions, or call in the factory with a microphone. The maintenance result registered for the mechanical abnormality is registered by taking a memo of the maintenance content and manually inputting the memo content into the computer. Also,
The vibration and temperature of the production line are measured at abnormal times or at regular intervals, and how to retain the data is recorded in a memo and the memo is manually input to a computer.

[0003]

However, when a mechanical abnormality is found, it is necessary for the person in charge to instruct the person in charge to instruct the person in charge of the processing by verbal, memo instruction, microphone or the like. It takes time to be transmitted, and it is often impossible to take appropriate and prompt processing. This tendency is particularly strong in a spinning factory where one worker is in charge of a large number of spinning machines, and when the maintenance staff wants to give instructions to a maintenance staff who can repair the machine in which a failure has occurred, the maintenance staff is far away. It is not uncommon to be present.

Further, it is troublesome to register the maintenance result for a machine abnormality by taking a memo of the maintenance content and going to a computer installed away from the machine that has repaired the content of the memo and manually inputting the content. Not only that, but the format of input to the computer is different for each worker, and it is easy to lack uniformity.

Further, it is a troublesome work to measure the vibration and temperature of the production line at abnormal times or periodically, take a note of the measured value, and manually input the note into the computer.

Therefore, the object of the present invention was made in view of the above-mentioned problems. When a machine abnormality is detected, a processing instruction is appropriately and promptly transmitted to a person in charge of the machine and the processing result is accurately obtained. It is to provide a machine abnormality notification system that can be collected.

[0007]

In order to achieve the above object, the in-plant abnormality notification system of the present invention is connected online to a machine management device for collecting and managing data from a machine-equipped sensor of a spinning factory. The maintenance computer that receives, stores, and processes the data of the above machine and calls the abnormality of the above machine by the wireless transmitter via the control device, and each worker carries it to receive this wireless notification, and the abnormality is given to the worker by sound or vibration. And a wireless receiver having a function of notifying the occurrence of the failure and a simple message display function of notifying the failure target and the details of the failure.

[0008]

Function: The maintenance computer sends a message to the person in charge directly from the maintenance computer via a wireless transmitter with a message. This is received by the radio receiver carried by each worker. Each worker knows the occurrence of the abnormality by the sound or vibration of the wireless receiver, and from the display contents by the message display function, the process,
Know the failure target such as machine number and simple failure details. Therefore, the worker directly goes to the machine of the relevant process and machine number, or after grasping the details on the screen of the maintenance computer, goes to the relevant machine, and performs maintenance processing such as repair of the machine if necessary. .. The registration of the result after the worker has performed the necessary processing is performed, for example, by the worker inputting it to the machine control device or by inputting it to the maintenance computer by means such as an IC card or wireless. Can be collected by. This may be done by providing the machine management device and the maintenance computer with a function of registering the result after the worker has performed necessary processing.

As described above, when a machine abnormality is found in the spinning factory, the processing instruction can be appropriately and quickly transmitted to the person in charge of the machine, and the processing result can be collected without error.

Reference numeral 3 denotes a failure diagnosis computer that can access the database 2, and has a main function of the failure diagnosis expert system. 4 is 1 of each process of the spinning factory
It is a machine management device that collects and manages data from various machine-equipped sensors (not shown) that are installed for each machine and that is provided for each machine that constitutes one machine. It has an on-board computer 5 and a machine terminal 6 connected to it. Here "one machine"
Is composed of one or a plurality of spinning machines, depending on the process and its scale. For example, in the case of a drawing process, one or a plurality of drawing machines constitutes one machine, and in a spinning or rewinding process, usually a large number of spinning machines are used. The spindle constitutes one spinning machine or winder. In the case of this embodiment, the machine frame management device is installed in the production line 7 of the package P after the rewinding process.

Reference numeral 8 is a data recording type vibration measuring instrument for detecting and measuring the vibration of the detection production line 7 by a sensor 9, and 10 is a data recording type temperature measuring instrument for detecting and measuring the temperature of the production line 6 by a sensor 11. Each measured value is input to the security computer 1 by a so-called IC card. However, mechanically fixed sensors can be automatically entered into the maintenance computer 1.

A wireless transmitter 13 is connected to the maintenance computer 1 via a call control device 12, and each worker carries a wireless receiver 14 which receives a notification by this wireless communication. We are building a machine abnormality notification system that notifies workers of machine abnormalities. A worker is a maintenance worker 15 who can repair complicated machines, and a so-called stand operator 16 who goes around the machine to check and set products, support cans, handle end-downs, and replace full-wrapped packages. The wireless receiver 14 is carried by both of them. Here, the wireless receiver 14
Has a function of notifying an operator of occurrence of an abnormality by sound or vibration and a simple message display function of notifying a failure target and details of the failure, and in the present embodiment, is a so-called pager. Reference numeral 17 denotes a so-called electronic notebook, the IC card of which can be inserted into the security computer 1 and the contents thereof can be input to the security computer 1.

The role of the security computer 1 is to receive, store and process various data described above, process data for wireless notification, and display a screen for notifying the worker of details of abnormality information. The information displayed on the screen of the display device CRT of the maintenance computer 1 includes the machine operating status (status), operating instructions to the operator, abnormal maintenance instructions to maintenance personnel, periodic maintenance instructions to maintenance personnel, failure history, maintenance. It contains various information such as history, relationship between spinning and regular maintenance. Data such as a maintenance plan, maintenance implementation, machine specifications, operating conditions, and yarn thread types are registered in the database 2 and shared by the failure diagnosis expert system.

Now, the measuring device 8 for measuring the vibration and the humidity of the machine,
The measurement data at 10 is input to the security computer 1. Further, failure information automatically output from various sensors (not shown) with machines provided for each machine is directly transmitted from the on-board computer 5 to the maintenance computer 1.
Or via the machine terminal 4.

The maintenance computer 1 monitors whether or not there is a machine abnormality in the factory. The contents of the abnormality include an abnormality in quality, for example, the detection of a machine (front spinning) that is out of the control limit, and an abnormality in operating rate, for example, the detection of a machine (front spinning) below the control limit. When the maintenance computer 1 finds an abnormality in these machines in the factory, the maintenance computer 1 uses the wireless transmitter 13 via the call control device 12 to call the worker, the process to which the corresponding machine belongs and the machine number. , Whether the required worker is a maintenance worker or an operator is discriminated, and a simple failure content is reported by radio. The wireless receiver 14 carried by each worker first responds to the calling of the worker among the wireless notifications and notifies the worker by sound or vibration. Then, the display unit of the wireless receiver 14 displays the machine base number or weight number of the corresponding machine and the type of worker required.

The worker corresponding to the displayed contents can go directly to the side of the machine shown in the display, or can know the details of the abnormality, the display device CRT of the maintenance computer 1.
Go to and check the status on the CRT screen. This includes
In addition to grasping the current state of the machine, grasping past failure history is also included. Then, necessary processing such as repair is performed on the corresponding machine. Therefore, in this machine abnormality notification system, when a machine abnormality is found, the maintenance computer sends a message directly to the person in charge via a wireless transmitter, and processes the process, machine number, etc. The contents can be instructed, and appropriate and prompt processing can be performed by an appropriate person in charge of machinery.

After performing the necessary processing such as the above-mentioned repair of the machine, the operator manually inputs the result into the machine terminal 6 of the machine base management apparatus 4, or the maintenance computer 1 through the IC card. To enter. In the latter case, the worker first registers the processing result in the electronic notebook 17. By this operation, the registration result is recorded in the IC card of the electronic notebook 17. The operator inserts the IC card into the security computer 1 and inputs the registration result into the security computer 1. However, the registration result can be input to the maintenance computer 1 by wireless communication or the like, if necessary. The contents registered via the electronic notebook 17 or the machine terminal 6 include machine number, weight number, date (year / month / day), maintenance start time, maintenance end time, part number,
Failure causes (major category, middle category, minor category), countermeasures, etc. The maintenance computer 1 receives and stores these data, and uses them as diagnosis data for the next machine abnormality in the failure diagnosis expert system.
