DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

In a spinning factory, for example, a cotton yarn spinning factory, a cotton yarn to be a product is produced through a blended cotton process, a carding process, a combing process, a drawing process, a roving process, a spinning process and a rewinding process.

The kneading cotton process is a process in which various kinds of raw cotton are appropriately mixed according to the thickness of the yarn to be spun and the intended use, and then the raw cotton is opened and loosened to produce a sheet-shaped wrap. For this, a mixed-punch machine 1 such as an opener is used. In the carding process, elastic fiber cloth, metal fiber cloth, etc. are used to loosen the fibers in the wrap until they are separated into individual fibers, and the curving fibers are stretched in the lengthwise direction and bundled together to form a string-shaped card sliver. The carding machine (card) 2 is used in this step. After the carding process, the combing process is performed by the sliver wrap 3 and the ribbon wrap 4, and then the combing process is performed.

The combing step is a step necessary for producing a high-quality yarn having a long fiber length. Therefore, the comb 5 is used to remove even shorter fibers from the sliver, and the length of the fibers constituting the sliver is reduced. Produces comb sliver by making the aligned fibers more parallel. The drawing process is the drawing machine 6
Is a process for parallelizing fibers in the same manner as the carding process, and produces a filament sliver. In the roving process, a roving machine 7 is used to draft a drawn sliver or a card sliver, and a roving is produced by stretching it to some extent and giving a slight twist. The spinning process is a process in which the ring spinning machine 8 is used to stretch the roving yarn produced in the roving process to a desired thickness and apply necessary twist to finish the yarn. The winding step is a step of rewinding the spun yarn produced by the spinning process using the automatic winder 9 into a package to a desired length.

By the way, in order to continuously produce spun yarn of a certain quality, it is necessary to carry out maintenance work for constantly managing the states of the various spinning machines 1 to 9, and to carry out swift and appropriate maintenance work. In order to carry out, it is necessary to accumulate the maintenance data for each spinning machine and to perform statistical processing to standardize the maintenance data.

Therefore, in the present invention, as shown in FIG. 1, the spinning machine control devices 1a, 2a, 3 for collectively controlling and controlling the spinning devices 1-9, which are respectively provided for respective processes, are collectively centralized.
