Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention uses a plurality of automatic machines that perform operations such as pipe change, line change, and yarn splicing, which are necessary for the operation of many spinning machine stands. In this case, the present invention relates to a method of controlling the operation of the automatic machine.

(Prior Art) Conventionally, a pipe changer has been generally used as an automatic machine that automatically performs a pipe change operation when a spinning machine is full of pipes. For example, automatic machines other than the tube changer have been proposed, and an automatic machine for changing the tube of the roving frame has also been proposed. In general, in these automatic machines, one automatic machine is in charge of a plurality of spinning machine stands because of its work interval and capacity. In the spinning process, a large number of machines are installed side by side, and a number of automatic machines are often required. The automatic machine generally moves along a rail laid on the side of the end of the spinning machine stand, and stops at a position corresponding to the machine stand requiring work to perform work on the machine stand. Therefore, in order to prevent the automatic machines from colliding with each other, the assigned machine base is specified in advance, and the operation thereof is controlled so as to move on the rail within a range corresponding to the assigned machine base.

(Problems to be Solved by the Invention) Since the moving range of each automatic machine is set in advance as described above, when a part of the automatic machine becomes inoperable, the spinning machine that the automatic machine was in charge of The work of the table was manually performed by the worker. Therefore, there has been a problem that the work efficiency is lowered and the operating efficiency of the spinning machine stand is also lowered.

By the way, in general, when a plurality of automatic machines are used, the number of spinning machine stands which each automatic machine is in charge of is a number that can be sufficiently supported without exhibiting the maximum working capacity of the automatic machines.
Further, the working intervals of the spinning machine stand differ depending on the spinning conditions, and in the case of producing fine count yarns, the tube replacement interval, the thread replacement interval, etc. become long, so that the working capacity of the automatic machine has a sufficient margin. The present invention has been made paying attention to this point,
The purpose is to control the operation of an automatic machine that can reduce the operating efficiency of the spinning machine stand by minimizing the amount of manual work by the operator when a part of multiple automatic machines becomes inoperable. Is to provide a method.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a plurality of pipes that automatically perform operations such as pipe replacement, replacement, and yarn splicing necessary for the operation of a number of spinning machine stands arranged in parallel are provided. One automatic machine is used, and each automatic machine has its own machine stand so that the number of machines in the machine is less than the maximum work capacity of each machine. When it becomes impossible, the number of receiving machines of other automatic machines is increased so that other automatic machines can work on the receiving machine stand of the automatic machine.

As a method of changing the number of receiving machines, an instruction to input the work request signal from each machine to each spinning machine base and determine the priority order is given to the automatic machine by the signal from the control device. A device is provided, and the control device divides the spinning machine groups into groups and issues a signal to exchange the instruction signal with a specific automatic machine for each group, and a part of the automatic machine becomes inoperable. In such a case, the machine base corresponding to the automatic machine will be transferred to another group.

In addition, as another method, it reciprocates along rails laid on the side of a large number of spinning machine stands, and stops at a position corresponding to the spinning machine stand issuing the work request signal A plurality of automatic machines that perform work are installed, and each automatic machine is always reciprocated within a range corresponding to the receiving machine base by detecting the detected object provided along the rail When a part of one of the automatic machines becomes inoperable during operation, the arrangement position of the detected object is changed to expand the moving range of other automatic machines.

(Operation) In the present invention, a plurality of automatic machines such as a pipe changer and a Shine changer that perform operations such as pipe change and Shine change necessary for operation of a plurality of spinning machine stands installed side by side are used. The number of machines less than the maximum work capacity is defined as the number of receiving machines, and a predetermined work is performed according to a work request signal from the receiving machine base. When a part of multiple automatic machines becomes inoperable, the number of receiving machines has been set with a margin of work capacity until then, and the maximum number of receiving machines of other automatic machines Instead of the operator manually performing all work on the increased machine stand-by machine, the operator only performs work on machines that cannot be covered by other automatic machines. It will be better.

(Embodiment 1) A first embodiment of the present invention will be described below with reference to FIG. A rail 2 is laid on one end of the spinning machine frame 1 installed in parallel with one another in a state of being orthogonal to the longitudinal direction of the spinning machine frame 1. The automatic machine 3 for performing pipe changing work or shining change work is moved to a position corresponding to the carrier 3a moving on the rail 2 and the spinning machine base 1 which is mounted on the carrier 3a and requires the work. It is composed of a working machine 3b which runs along a guide rail 1a extending along the spinning machine base 1. Each spinning machine base 1 is provided with a work request signal transmitting device 4 such as a pipe replacement request signal transmitting device or a replacement request signal transmitting device, and outputs a work request signal to the control device 5.

The control device 5 is a central processing unit (hereinafter referred to as CPU) that receives a work request signal from each spinning frame 1 and performs arithmetic processing.
6 and a read-only memory (RO
M) 7 and a readable and rewritable memory (RAM) 8 for temporarily storing the arithmetic processing result and the like, and the CPU 6 operates according to the program stored in the ROM 7. The CPU 6 divides the many spinning machine bases 1 into two groups, one group corresponding to the first machine I and the other group corresponding to the second machine II, respectively, based on the work request signal from each of the spinning machine bases 1. A priority order is determined within each group, and a signal for supporting the next work machine base is output to the automatic machine to the instruction device 9 provided at the end of each spinning machine 1. The instruction device 9 is configured to be able to instruct the carrier 3a whether to stop or move, that is, whether to rotate the drive motor forward or backward. After the work machine 3b is mounted on the carrier 3a after the work is completed, the CPU 6 is provided on the first spinning machine board 1 having the first priority if there is a work request from another spinning machine board 1 in the same group. The instruction device 9 is instructed to issue a signal for instructing to stop the carrier 3a, and whether the spinning machine base 1 is in the left or right direction of the spinning machine base 1 in which the carrier 3a is currently stopped. Is calculated, and the instruction device 9 is instructed to issue a signal indicating the direction. Also, carrier
A sensor 10 for detecting an instruction signal from the pointing device 9 is provided at 3a.

The control device 5 is provided with a changeover switch S, and when the automatic machines 3 are in a normal state and when the No. 1 machine I or No. 2 machine II becomes inoperable, the spinning machine base 1 in charge of each automatic machine 3 is The control program is changed to be different. This switching operation can be activated by the ON signal of the sensor 11 that detects the operation of the automatic machine 3 which has become inoperable when the automatic machine 3 is placed at the retracted position provided at the end of the rail 2.

Next, the operation of the device configured as described above will be described.
Both automatic machines 3 are capable of working on 6 spinning machine bases, but normally they are in charge of 4 spinning machine bases 1 and the first machine I is
The N1 to N4 spinning machine bases, the second machine II is in charge of the N5 to N8 machine bases, and detects the signal of the indicating device 9 by the sensor 10 at a position corresponding to the spinning machine base 1 that needs work. The work machine 3b is stopped and a predetermined work is performed.

When one of the automatic machines 3 becomes unworkable, the worker moves the automatic machine to the retracted position. When the automatic machine 3 is moved to the retracted position, the sensor 11 detects it, and the changeover switch of the control device 5 is switched by the detection signal, and the instruction of the work machine table to the other automatic machine, for example, No. 1 machine, is changed. The process is performed based on the work request signal from the machine 1 for all spinning machines including the machine which was in charge of No. 2 machine II. That is, the CPU 6 determines the order of priority of the work request signals from the respective machine bases 1, and the automatic machines 3 according to the priority order.
A command signal for instructing the traveling direction and the like is output to each instructing device 9. Since the ability of the automatic machine 3 is insufficient to handle all the spinning machine bases, it is necessary for the operator to assist the work. Therefore, when a work request signal is issued from another machine while the first machine I is working, the CPU 6 turns on the lamp L provided on the machine to notify the operator of the work, and Instead of performing the work by the automatic machine 3, the work is entrusted to the worker. After the work is completed, the work machine 3b is the carrier
Even when the machine 3 is mounted on the machine 3a, if there is no work request signal from another machine, the automatic machine 3 stands by at a position corresponding to the machine 1. Then, when a work request signal is issued from another spinning machine base 1, the controller 5 calculates the positional relationship between the machine base and the automatic machine 3, and causes each instruction device 9 to move in the moving direction of the automatic machine 3. A signal is issued to instruct the stop machine and the automatic machine 3
The sensor 10 detects the signal and moves to a position corresponding to the spinning machine frame 1 requiring work, and stops, and the work machine 3b performs the required work. After the repair of the No. 2 machine II is completed and the machine is moved to the inside of the rail 2, the switching device is switched again, and both automatic machines 3 are in charge of the work of one group of the spinning frame 1 divided into two groups. .

Second Embodiment Next, a second embodiment will be described with reference to FIG. In this embodiment, when each automatic machine 3 is not working on the spinning machine base 1 by the working machine 3b, that is, when the working machine 3b is mounted on the carrier 3a, the work requesting stand is always detected. Therefore, the point that it is configured so as to reciprocate on the rail 2 within a range corresponding to the spinning machine frame 1 in charge is greatly different from the above-described embodiment. In the vicinity of the rail 2, the detected bodies 12a to 12d are provided at both ends corresponding to the spinning machine frame 1 in charge of the movement range of each carrier 3a.
3a is provided with sensors 13a and 13b for detecting the detected objects 12a to 12d. In each carrier 3a, when one sensor 13a detects the objects 12a to 12d to be detected, a drive motor (not shown) is driven in reverse, and the other sensor 13b detects the objects 12a to 12d to be detected. Even if the motor is stopped due to the work in 3b, the motor will be driven again in the same direction when it is restarted. A lamp is used for the detected objects 12a to 12d,
Photoelectric switches are used for the sensors 13a and 13b. Therefore, when the lamp is turned on, each sensor 13a, 13b
It becomes possible to detect a and 12b. An indicator light 14 for displaying a work request is provided at the end of each spinning machine base 1, and the carrier 3a has a sensor 15 at a position where the indicator light 14 can be detected when the carrier corresponds to the spinning machine base 1. Is provided.

When both automatic machines 3 are in a normal state, all the lamps of the detected objects 12a to 12d are turned on, and the moving direction of the No. 1 machine I is changed each time the sensors 13a, 13b detect the detected objects 12a, 12b. Move on the rail 2 corresponding to the spinning machine base, and move to Unit 2 II
Each time the sensors 13a, 13b detect the objects 12c, 12d to be detected, the moving direction is changed and the sensors 13a, 13b reciprocate on the rail 2 corresponding to the spinning machine base 1 in charge. Then, when the sensor 15 detects the indicator light 14 in the lighting state of the spinning machine base 1 that requires work, it stops at a position corresponding to the spinning machine base 1 and the working machine
Work according to 3b. One automatic machine 3, for example, No. 2 machine II
When it becomes impossible to work, the operator moves the No. 2 machine II to the retracted position and then operates the changeover switch (not shown) to change the state of the lamps of the detected bodies 12b, 12c to the off state. As a result, Unit 1 I, which has been moving between the detected objects 12a and 12b until then, does not detect the detected object 12b even when the sensor 13b moves to a position corresponding to the detected object 12b. Object to be detected 1 that continues to move and sensor 13b is lit
The moving direction is changed when 2d is detected. Therefore, the No. 1 machine I can also move on the rail 2 corresponding to the spinning machine frame 1 which was previously in charge of the No. 2 machine II. In this state, Unit 1 I is reciprocating on the rail 2 while moving to the indicator light.
14 is stopped at a position corresponding to the spinning frame 1 that is lit, and a predetermined work is performed by the working machine 3b. Further, when the indicator light 14 of the other spinning machine base 1 is turned on while the automatic machine 3 is working, the worker performs the work of the spinning machine base 1 concerned. Unit 2 II
After the completion of the repair of No. 1 machine I moved between the detected bodies 12a, 12b, the operator operates the changeover switch to detect the detected body 12b, 12b.
Turn on the 12c lamp. By this, both automatic machines 3 again
Moves on the rail 2 within a predetermined movement range in the normal state.

It should be noted that the present invention is not limited to the above-described embodiments, and for example, in the first embodiment, the other automatic machine can also perform the work of the spinning machine other than the spinning machine base that was previously in charge. In the case of switching, instead of deciding the work priority order of the automatic machine 3 in the order of generation of work request signals from all the spinning machine bases 1, the work request signals from the original receiving machine bases are prioritized, or the instruction device Carrier as an instruction method by 9
Instead of instructing the moving direction of 3a, a machine frame number may be given to each spinning machine frame in advance, and the machine frame number and, if necessary, the R side and the L side may be specified. In addition, in the second embodiment, the object to be detected is set to each spinning machine base 1
May be provided at positions corresponding to the end portions of the above, and the detection object for lighting the lamp can be selected by the changeover switch so that the moving range of the automatic machine 3 can be changed in multiple stages. Further, proximity switches are used as the sensors 13a and 13b, and a dog 16 is provided as a detected object in place of a lamp so as to be rotatable between a position facing the sensors 13a and 13b and a retracted position as shown in FIG. Good. Further, instead of the automatic machine 3 which is composed of the carrier 3a and the working machine 3b, for example, Japanese Patent Laid-Open No. 62-
As in the bobbin supplying / discharging device disclosed in Japanese Patent No. 238832, the work should be carried out at a position corresponding to the machine base that moves along the rail 2 and requires work, and JP-A-62-51574.
The carrier and the working machine may be integrally configured as in the automatic machine disclosed in Japanese Patent Laid-Open Publication.

(Effects of the Invention) As described in detail above, according to the present invention, when a plurality of spinning machine pedestals are provided and a part of an automatic machine that performs a work such as a pipe change and a line change becomes inoperable. In addition, since some automatic machines that cannot be operated by other automatic machines can take over some of the work of the spinning machine stand that had been in charge until then, it is different from the conventional method until the failed automatic machine is restored by the operator. The amount of work is reduced, and the reduction in the operating efficiency of the machine base can be minimized. Further, in the method of changing the work range of the automatic machine, that is, the number of the receiving machines by changing the arrangement position of the detected object detected by the sensor equipped in the automatic machine, it is necessary to prepare a plurality of control programs in advance. It is possible to make changes with simple switching operations.
