Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management system for a warp knitting machine, and more particularly to a management system capable of managing information such as a thread rise of a pattern beam even at a place remote from the machine.

[0002]

2. Description of the Related Art Conventionally, the operation status of a warp knitting machine has been managed using a knitting machine control box attached to the machine. For example, the drive of the beam wound with ground yarn and the yarn rise are signaled by a computer connected to the machine to which the warping information, knitting data, etc. are input to the servomotor that drives the beam axis. It is issued and the ground yarn is supplied and automatically stopped, but these are carried out for each knitting machine, and are performed using a control box connected to the knitting machine by wire. .

[0003] For this reason, knitting machine management is necessary for each individual knitting machine, and it has always been necessary to implement it near the knitting machine.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to manage a plurality of knitting machines at a small cost, and to manage a warp knitting machine without necessarily being close to the knitting machine. To provide a management system.

[0005]

A management system according to the present invention transmits various management information from a warp knitting machine to a PHS (simplified portable telephone), via a control computer connected to the knitting machine.
It is configured so that management information can be fed back to the knitting machine side by remote control using the communication means by taking it into data communication means such as a mobile phone. Information can be obtained, and the management of the knitting machine can be carried out even in a factory and without any time limitation.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the case where the management information is the pattern beam supply state, the pattern beam such as the number of turns of the pattern beam, the diameter of the pattern beam, and the outer diameter of the warp pattern yarn is determined in advance during the aging of the pattern beam. By inputting the warping information into the control computer, the pattern beam is set on the knitting machine, and when the knitting machine is operated, the management information on the pattern yarn use status and the yarn rising time is transmitted through the control computer. It can be received via a PHS or the like, and can transmit a necessary management signal according to the situation, for example, a knitting machine stop signal at the time of yarn rising. As a result, it is not necessary to reside and monitor in a factory where a plurality of knitting machines are installed, and efficient factory management can be performed.

[0007]

FIG. 1 is an explanatory diagram showing a schematic configuration of an embodiment of a management system according to the present invention, and FIG. 2 is a chart showing a signal flow of the system in the embodiment.

In FIG. 1, reference numeral 1 denotes a knitting machine, which includes a yarn supplying section having a pattern beam 2 and a ground beam 3, a knitting section having a guide bar group 4 and a needle row N, a winding roller 5, and the like. And a drive unit provided with a patterning unit (not shown) for shogging the guide bar group 4 and a cam 6 and the like.

In the yarn supplying section, a ground yarn 7 is supplied from the ground beam 3 and a pattern yarn 8 is supplied from the pattern beam 2 to the needle row N.
In recent years, as is well known, the ground beam 3 is actively fed by a servomotor or the like, but the pattern beam 2 has a different yarn feeding ratio for each knitting course depending on the pattern of each pattern yarn. At present, a method of passively feeding the knitting portion based on the pull-out torque of the pattern yarn 8 is generally used at present.

As one embodiment of the present invention, when the object of the management information is a pattern beam, a shaft 9 is sandwiched on one side of each pattern beam 2 in which a pattern thread 8 is wound in FIG. A rotation detection piece 11 is attached to 10, and a rotation detection sensor 12 is provided to the rotation detection piece 11 so that a signal can be transmitted in accordance with the rotation of the pattern beam 2.

Reference numeral 13 denotes an input / output board, 14 denotes a computer, and 16 denotes a data communication PC card. The input / output board 13 and each pattern beam 2 are connected to signal lines S1, S2, S3,.
.. Are connected by Sn. A signal line St is connected from the input / output board 13 to the machine stop circuit 15. Further, the computer 14 is connected to the input / output board 13 by a signal line Sc, and a data communication PC.
PH as a wireless data communication means via the card 16
An S (simplified mobile phone) 17 is provided so as to be connectable.

Further, ground beam information 18, knitting machine speed information 19, thread breakage information 20, and winding information 21 from the warp knitting machine 1 are input to the input / output board 13 via well-known output means. .

Here, the operation state of the management system when the management target is the pattern beam 2 will be described. When the knitting pattern beam 2 is rotated by the pattern thread 8 drawn out according to the pattern configuration, the rotation detection sensor 12 inputs the rotation state of the pattern beam 2 to the input / output board 13 as a signal, and further processes the program according to the program determined by the computer 14. Then, the pattern yarn rising time at the current rotational speed is predicted, and if necessary, a radio wave is transmitted from the PHS 17 as a transmitting means via the PC card 16 for data communication, and the receiving means waiting at a place other than the warp knitting machine 1 To the PHS 17a. The received information is the data communication PC card 1
The information is displayed on the display 23 by the personal computer 22 via the display 6a.

When transmitting the management information, for example, a knitting machine stop command, to the warp knitting machine 1 using the PHS 17a as the transmitting means, the PHS 17 of the machine is used for the receiving means, and the signal Sp as the receiving information is transmitted to the computer 14 by the computer. Stop signal St from the input / output board 13 in the knitting machine control box 24
Is issued, and a stop signal of the operation of the warp knitting machine 1 is issued from the machine stop circuit 15.

Of course, in addition to the PHS, a mobile phone can be used. In addition to the use of these telephone lines, if the communication distance is relatively short, communication means such as a transceiver provided with data transmission / reception means can be used. Use is also possible.

The above description is directed to a case where the pattern beam supply state is a management target. However, the operation state such as the yarn rise state of the ground beam, the yarn breakage of the ground yarn and the pattern yarn, the number of revolutions of the knitting machine, etc. Similarly, regarding the winding status such as the winding length of the knitted fabric, the data communication means such as PHS can be used to control the radio wave even in a place remote from the target knitting machine in the factory or a remote place outside the factory. Within this range, comprehensive management of the knitting machine, such as acquisition of information to the knitting machine or operation instructions to the knitting machine, can be freely performed.

[0017]

As described above, according to the warp knitting machine management system of the present invention, it is not necessary to perform various managements of the warp knitting machine facing the knitting machine, and it is possible to manage a plurality of machines simultaneously. Therefore, labor saving and unmanned operation can be achieved, and a reliable system can be constructed at relatively low equipment cost.

In the case where the object to be managed is the pattern beam supply state, efficient replacement of the pattern beam can be performed, which leads to an improvement in operating efficiency.
