Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention comprises a spinning machine such as a ring spinning machine and a ring twisting machine, and a peripheral device that performs incidental operations such as pipe changing and roving changing necessary for the operation of the spinning machine. The present invention relates to a method of controlling a spinning machine and its peripheral devices in a spinning system.

[Prior Art] In recent years, labor-saving and automation have progressed in spinning factories, and machines have come to automatically perform associated operations such as pipe changes and roving changes necessary for operating spinning machines.

Conventionally, a tube changer was used as a main body of a spinning machine or its peripheral equipment,
As shown in Fig. 5, the roving changer etc. is composed of an R machine part M and a control part C, and each control part C has control hardware H.
and software S are provided, respectively, and are configured as one system that operates in conjunction with each other without interfering with each other by exchanging signals between the spinning machine main body F and peripheral devices.

[Problem B to be solved by the invention] In the conventional device, control hardware and software are required for each of the spinning machine main body and peripheral devices.
This not only requires additional space for installing the hardware, but also increases costs. On the other hand, in this type of spinning machine, peripheral devices (for example, pipe changing devices) are generally not operated when the spinning machine main body is in operation, but are operated when the spinning machine main body is stopped. In addition, in a spinning factory, in order to make effective use of floor space, a large number of spinning machines are arranged at minimal intervals, and it is generally necessary to avoid tasks such as changing tubes and rovings on adjacent spinning machines at the same time. The entire operation is scheduled to take place. Therefore, if all the peripheral devices are equipped with their own control hardware and software, the system as a whole has unnecessary duplicative equipment.

The present invention has been made in view of the above problems, and includes:
The object is to provide a method for controlling a spinning machine and its peripheral devices, which can reduce the space occupied by the control section and simplify the entire system.

[Means for Solving the Problems] In the present invention, to achieve the above-mentioned object, in a spinning system equipped with peripheral devices that perform incidental operations such as tube change and roving change necessary for the operation of the spinning machine, At least a part of the control section of the peripheral device of the spinning machine is also used as the control section of the main body of the spinning machine or other peripheral devices.

As a dual-use form of the control section, a part of the control section of the spinning machine main body may also be used as the control section of the peripheral device.

Further, the control section of the peripheral device may also be used as the control section of the peripheral device of another spinning machine main body.

[Function] In the present invention, at least hardware that is a control unit of a tube changer and a roving changer that are peripheral devices of a spinning machine, such as an inverter for controlling a motor and its control device, or software that is a control program, is provided. A portion is shared with the control section of the spinning machine itself or other peripheral devices. By sharing the control section, the space occupied by the control section is reduced, and extra wiring becomes unnecessary.

[Example 1] An example embodying the present invention will be described below with reference to Fig. 1.2. As shown in FIG. 2, a spinning frame 1 as a main body of the spinning machine is equipped with a full spindle-valve hole pipe changing device 2 of a known configuration (for example, Japanese Patent Application Laid-Open No. 51-40438) as a peripheral device.
is equipped with. A main motor 3 for driving a spindle and the like is controlled via an inverter 5 based on an output signal from a control device 4 constituting a control section. The tube changing device 2 also uses a motor (not shown) as a drive source for the horizontal pantograph R 8 that moves up and down a dotting bar 7 equipped with a bobbin gripping device (not shown) provided corresponding to each spindle 6. The motor is also driven and controlled via an inverter 5 based on an output signal from a control device 4. That is, the inverter 5 and the control device 4 that constitute the hardware unit 1 of the control section C are connected to the spinning frame frame 1 and the tube change equipment 'f! , 2.

The control device 4 includes a central processing unit (hereinafter referred to as CPU) 9,
Read-only memory (ROM) that stores control programs
A working memory 11 consists of a readable and rewritable memory (RAM) that temporarily stores calculation results etc. in the CPU 9.
PU9 operates based on program data stored in program memory 10. The program memory 10 stores a control program as software for the spinning R machine body and a control program as software for the tube switching device 2. Each of the control programs is created so that the main motor 3 and the drive motor of the pantograph mechanism 8 cannot be driven at the same time. The control device 4 is integrally incorporated with an input device 12 for inputting spinning conditions such as spinning count, draft ratio, and grain height spindle rotation speed.

Next, the operation of the apparatus configured as described above will be explained. During the operation of the spinning am machine 1, the main motor 3 is driven and controlled via the inverter 5 by a control signal from the control device 4 based on the spinning conditions inputted by the input device [12, and the rotation speed of the spindle 6 is controlled. Driving is performed so as to change according to a predetermined speed change pattern. After the pipes are full and the machine is stopped, the pipe changing device 2 is activated, and the drive motor of the pantograph 1!1118 is driven and controlled via the inverter 5 by a control signal from the control device 4.

There is no need to change the tube while the spinning frame 1 is in operation, and an interlock circuit is required to prevent the tube changer 2 from being activated by mistake. However, in the apparatus of this embodiment, the main motor 3 of the spinning machine R frame 1 and the drive motor of the pantograph II oval 8 of the tube changer 2 are drive-controlled via a common inverter 5, and both motors are operated at the same time. Since the control program is configured in such a way that driving is disabled, there is no need to install a special interlock circuit between the spinning frame frame 1 and pipe switching device 2, and there is no possibility of mutual interference, and the control unit The wiring between the inverter 5 and the control device 4 that make up the spinning machine frame 1
Since it can be shared by the pipe switching device 2 and the pipe switching device 2, wiring work etc. is also simplified.

[Example 2] Next, the second fruit 11R will be explained according to FIG.

In this embodiment, a plurality of adjacent spinning frame machines I
Pipe replacement for all spindles and valve holes installed on A, IB, and IC! 2A, 2B, and 2C are one controller unit as its control unit! 13 in common, which is a major difference from the previous embodiment. The control device 13 is equipped with a control program that controls only one pipe switching device at a time. Therefore, there is no need to increase the capacity of the CPU, program memory, working memory, etc. of the opening control device 13.

If the tube switching devices 2A, 2B, and 2C of multiple adjacent spinning machines IA, IB, and IC operate at the same time, it may be a hindrance to workers passing through or working between adjacent spinning machines. Conventionally, measures have been taken to prevent this from occurring by interlocking each device. In this embodiment, each pipe switching device 2A, 2B, 2CCi control CIE device Z 13 (7) is controlled in completely the same way by hardware H and software S, but they do not operate at the same time. Interlocking is automatically and reliably performed. Each pipe switching device 2A, 2B, 2C
Even if the inverters for controlling the motors for driving the pantograph mechanism are independently installed in the spinning frame IA, the spinning machine frame IA is equipped with them in the same manner as in the above embodiment.

IB, IC, and inverter 5 for controlling its main motor
may be shared.

Note that the present invention is not limited to the two embodiments described above. For example, in the second embodiment, instead of sharing the control device 13 between the pipe switching devices installed in adjacent spinning frame frames, The control device 13 may be shared between pipe switching devices that are located at different locations and do not operate at the same time. Further, as shown in FIG. 4, not only the hardware (I) but also a part of the software S may be shared between the spinning machine main body and peripheral devices. Also, instead of the full spindle-valve hole pipe changing device 2, a spinning tltfi machine 1 is used.
It can be applied to intermittent moving type tube changers and roving changers that move along Although it is difficult to install a large-capacity inverter, it is possible to use a large-capacity inverter by sharing the inverter of the spinning machine frame.

[Effects of the Invention] As detailed above, according to the present invention, the system is simplified by sharing part or all of the control section between the peripheral devices of the spinning machine or between the main body of the spinning machine and the peripheral devices. At the same time, not only does the space occupied by the control section become smaller, but the increased number of common parts reduces the labor involved in wiring work, etc., and ensures interlock between peripheral devices or between the spinning machine main body and peripheral devices.
