Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation management system in a cotton yarn spinning process.

[0002]

2. Description of the Related Art The process used in spinning cotton yarn is
For carding, drawing, roving, spinning, and winding, when using a comb, a combing process is inserted between the carding and drawing. This step will be described.

(A) Blended Cotton Process Raw cotton is blended (blended) according to the type of product, and the amount of cotton fed is kept constant during feeding of continuous cotton (cotton feeding) to open and remove dust. An air carrier or a wrap is formed in the next step.

(B) Carding process Fiber lumps sent from the blended cotton process are unraveled one by one
Separate the fibers into books and make a nearly parallel sliver.

(C) Combing preparation process The card sliver is reshaped into a wrap. That is, a large number of slivers are supplied to a sliver wrap machine (SLM), drafts are made to make wraps, and this is made to a finish wrap by a ribbon wrap machine (RLM).

(D) Combing step While advancing and retracting the wrap fed from the feed roller, the upper and lower combs remove short fibers to form a uniform sliver and store it in a can.

(E) Drawing Step A step of doubling a large number of slivers to make them uniform, and then giving a draft to them to align the constituent fibers in parallel is usually performed twice (Drawing 1 and Drawing 2).

(F) Rover spinning step The sliver is stretched to be thin, and the sliver is twisted to give strength and wound on a bobbin to form a roving.

(G) Spinning / Winding Process A roving is stretched to a required thickness and twisted to obtain a yarn having a required strength, which is wound up.

[0010]

By the way, each of these processes operates independently, and the whole process is not managed. Further, in recent years, efforts have been made to save labor, and although these steps are substantially automated, sliver replacement and the like are done manually. However, it is inefficient to allocate personnel to each work site, so it is desirable to operate with fewer workers, but it is difficult to check each machine with a small number of people because the factory is large. Moreover, waste tends to occur.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide an operation management system capable of performing less wasteful work in operating each process of spinning cotton yarn.

[0012]

In order to achieve the above object, the present invention inputs the operating status of each process from mixed cotton to wound yarn into a central control host computer, and at the same time According to the operation schedule, the work procedure manual is prepared.

[0013]

According to the above construction, the central management host computer grasps the operating status of the machine in each process and prepares the work procedure manual, so that the operator can perform the work according to the work procedure manual. Thus, you can move efficiently and work efficiently in a large factory.

[0014]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

First, the overall outline of each step of spinning cotton yarn will be described with reference to FIG.

In FIG. 2, 20 is a kneading cotton machine, 25 is a card machine, 30 is a sliver wrap machine, 35 is a ribbon wrap machine, 40 is a comb machine, 45 is a kneading machine, 50 is a kneading machine 2.
Machine, 55 is a roving frame, 60 is a spinning frame, 65 is a winder, 70
Is a package inspection device, and 75 is an automatic warehouse.

The sliver from the card machine 25 is a can 26
And is transported to the sliver wrap machine 30 by hand or by a transport device, and thereafter transported to the automated warehouse 75 by transport devices 36, 41, 46, 51, 56, 61, 66, respectively. In addition, these transport devices 36, 41, 46, 5
1, 56, 61, 66 are control devices 37, 4 respectively.
Drive control is performed by 2, 52, 57, 67 and 68.

The operating statuses of the blended cotton machine 20 and the card machine 25 are determined by the first computer 2 via the interface 21.
2, and the sliver wrap machine 30, the ribbon wrap machine 35, the comb machine 40, the drawing machine 1 45, the drawing machine 2 5
0 and the operating conditions of the roving frame 55 are input to the second computer 32 via the interface 31.

The sliver replacement information of the sliver wrap machine 30, the ribbon wrap machine 35, the first drawing machine 45, and the second drawing machine 50 is input to the control device 53. This control device 53
The control devices 37, 42 and 52 are input to the central management host computer 80 via the first data collection computer 44.

The operating conditions of the roving frame 55 and the spinning frame 60 are input to the control device 57 and the central management host computer 80 via the second data collecting computer 45.

The package information wound up by the spinning machine 60 is input to the third computer 62, the information is input to the fourth computer 63, and the winding information of the winding machine 65 is input to the fourth computer 63. Is entered.

These first to fourth computers 22, 32,
The information 62 and 63 is the central management host computer 8
0 is communicated.

The inspection result of the package inspection device 70 and the receipt information of the automatic warehouse 75 are the control device 67, respectively.
It is input to the fifth computer 69 via 68, and this information is also communicated to the central management host computer 80.

The automatic warehouse 75 is a storage computer 7.
