The roving changer 4 has basically the same structure as the roving changer disclosed in Japanese Patent Laid-Open No. 2-127368.
It is equipped with various devices that perform roving yarn exiting work, roving joining work, and bobbin replacement work in parallel. That is, the roving yarn changer 4 is a roving yarn feeding device for feeding the roving yarn end from the full bobbin F,
A roving splicing device that splices the new roving that has come out to the old roving and a bobbin exchanging device that exchanges the full bobbin F and the small bobbin B (both not shown) are in the advancing direction during operation (the same figure) Equipped sequentially from the front). These various devices are control devices C1 and C provided in the roving changers 4 and 4, respectively.
It is designed to be driven and controlled by 2. Roving changer 4
The frame 4a is partially opened on the front surface and the upper surface facing the machine base 1 for work by various devices, and the side surface and the rear surface are covered by the frame 4a.

As shown in FIG. 2, a monitoring camera 14 is installed via a bracket 13 on the upper side surface of the roving changer 4 on the traveling direction side during operation. Each of the monitoring cameras 14 is positioned so that the operation state of various devices mounted on the opposing roving changer 4 facing the machine base 1 can be photographed by the photographing lens 14a. The photographing performed by the surveillance camera 14 through the photographing lens 14a is performed through the space portion formed between the upper end of the draft part 9 and the lower end of the roving bobbin B suspended from the bobbin hanger 7. ing. Each of the monitoring cameras 14 and 14 is a control device C.
1 and C2 are electrically connected. Surveillance camera 14
The video image captured by is displayed in real time on a monitor monitor provided on a main control panel (not shown). Further, the angle of the monitoring camera 14 can be controlled in the vertical and horizontal directions from the main control panel, and it is also possible to photograph the work situation of the roving changer 4 on the own side. Furthermore, the surveillance camera 14 has a recording function, and the photographing magnification can also be changed.

A dog (detected portion) 15 is formed on a side surface (right and left side surfaces in the figure) of the machine base 1 at a position corresponding to the spindle in the machine longitudinal direction. Dog 15 in the roving changer 4
The sensor 16 is arranged at a position corresponding to. The sensors 16 and 16 are respectively connected to the control devices C1 and C2, and when the dog 15 is detected, an ON signal is output to the control devices C1 and C2. Then, the control devices C1 and C2
Is configured to stop the traveling of the roving changer 4 based on the ON signal from each sensor 16.

The control devices C1 and C2 can exchange signals with the control device C3 (shown in FIG. 1) of the carrier 3 through a trolley wire (not shown) installed along the machine base 1. Has become. Further, the control device C3 of the transport vehicle 3 is capable of exchanging signals with the main control panel via a trolley wire (not shown) installed along the rail 2.

As shown in FIG. 1, the control devices C1 and C2 provided in the roving changers 4 and 4 are microcomputers M, respectively.
Built-in C, microcomputer MC is ROM and R
A memory (not shown) including an AM and CPUs (central processing units) 17 and 18 are included. CPU 17, 18
Is adapted to execute a control program stored in memory. Further, the control device C3 arranged in the transport vehicle 3 has a built-in microcomputer MC including a memory 19 including a ROM and a RAM and a CPU 20. The CPU 20 executes the control program stored in the memory 19. Further, the memory 19 has a flag S for synchronous operation.
KLF and SKRF are set.

When the CPU 20 receives a work request signal from the main control panel, the transport vehicle 3 receives the work request signal.
And the two roving changers 4 and 4 are transported to the spinning machine stand 1 where the roving change operation is to be performed. CPU
When the carrier 3 reaches the spinning machine base 1, the CP 20
A shooting start signal P for operating the monitoring camera 14 and a work start signal A for starting the roving changer 4 are output to U17 and U18.

Based on the work start signal A from the CPU 20, the CPUs 17 and 18 start traveling from the stop position,
The roving changer 4, 4 is a cycle of a series of operations including traveling stop at the next stop position and roving change operation at the stop position.
Is to be done. The roving yarn changer 4 is provided with a sensor (not shown) that detects the completion of one cycle, that is, the completion of the roving yarn replacement work at each stop position, and the CPUs 17 and 18 set 1 based on the detection signal from this sensor. The completion of the cycle can be detected. The CPU 17 outputs a work completion signal S1 to the CPU 20 every time the L side (upper side in the figure) roving changer 4 completes one cycle, while the CPU 18 causes the R side (lower side in the same figure) roving change. Every time the machine 4 completes one cycle, the work completion signal S is sent to the CPU 20.
2 is output. When the work completion signal S1 is input from the CPU 17, the CPU 20 sets the synchronous operation flag SKLF to "1", and when the work completion signal S2 is input from the CPU 18, the synchronous operation flag SKR is set.
"1" is set to F. CPU20
After the work start signal A is output, when a predetermined time (time shorter than one cycle) has elapsed, the synchronous operation flag SKL
Only when both F and the synchronous operation flag SKRF are sequentially read and both are set to "1"
The work start signal A is output to 17 and 18 at the same time. Further, the CPU 20 resets the synchronous operation flags SKLF and SKRF to "0" each time the work start signal A is output. Both roving changers 4, 4
The traveling speeds when the vehicle is moving are set to be substantially the same.

Next, the operation of the roving yarn changer configured as described above will be described. Based on a work request signal from the main control panel, the carrier 3 moves to the spinning machine frame 1 where the roving replacement work is to be performed with the two roving changers 4 and 4 mounted on both sides. When the carrier 3 reaches the spinning frame 1, the CPU 20 of the carrier 3 outputs a photographing start signal P and a work start signal A to the CPUs 17 and 18. At that time, the synchronous operation flags SKLF and SKRF set in the memory 19 are “0”.
Is reset to. The CPUs 17 and 18 use the shooting start signal P
The monitoring camera 14 is actuated based on the above, and the roving changers 4 and 4 are started from the transport vehicle 3 based on the work start signal A. As a result, both roving changers 4 and 4 start simultaneously from the carrier 3 toward the spinning machine base 1 side.

When the sensor 16 detects the dog 15, the roving changer 4 stops traveling and starts the roving change operation at the stop position. Since the traveling speeds of the roving changer 4 are substantially the same, the roving changers 4 and 4 reach the respective stop positions almost at the same time and start the roving change operations substantially at the same time. The work statuses performed by the various devices provided in the roving yarn changing machine 4 are respectively photographed by the monitoring cameras 14 installed in the roving yarn changing machine 4 on the opposite side with the machine base 1 interposed therebetween. That is, the working state of the R-side roving yarn changing machine 4 is photographed by the L-side monitoring camera 14, and the working state of the L-side roving yarn changing machine 4 is photographed by the R-side monitoring camera 14.

When the roving changer operation at the stop position is completed and one cycle of the roving changers 4, 4 is completed, the CPUs 17, 18 of the roving changers 4, 4 are transferred to the CPU 20 of the transport vehicle 3. The work completion signals S1 and S2 are output respectively. When the CPU 20 inputs the work completion signal S1 from the CPU 17 of the L side roving changer 4, the synchronous operation flag SKL
Set "1" to F and CPU 18 of the roving changer 4 on the R side.
When the work completion signal S2 is input from, the synchronous operation flag SKRF is set to "1".

When a predetermined time (time shorter than one cycle) has elapsed since the work start signal was output, the CPU 20 sequentially reads the synchronous operation flag SKLF and the synchronous operation flag SKRF. Only when both are set to "1", the CPU 20 outputs the work start signal A to both the CPUs 17 and 18 at the same time. That is, when the roving change operation is not completed for one of the two roving changers 4, the CPU 20 sets the roving changer 4 that has completed the operation first to the coarse change of the other roving changer 4. Wait until the yarn change operation is completed at the stop position, and both start the next 1 after completing the roving change operation.
Start the cycle at the same time.

The CPUs 17 and 18 cause the roving changers 4 and 4 to start the next one cycle at the same time on the basis of the work start signal A input from the CPU 20 at the same time. Both roving changers 4, 4
Are opposed to each other during the traveling process up to the next stop position, and are also opposed to each other during the roving replacement work process at the next stop position. Therefore, the roving changer 4
Since the relative speed difference between the roving yarn and the monitoring camera 14 for photographing the roving changer 4 is almost eliminated, and the positional relationship between the two is kept constant during one cycle, the roving yarn is monitored by the monitoring camera 14. The work situation of the same predetermined place of the replacement machine 4 is photographed.

In this way, the roving changers 4 and 4 are synchronously operated and the respective cycles are performed in synchronization with each other, so that the monitoring camera 14 photographs the operating conditions of various devices at the same predetermined place. As a result, the image visualized on the monitoring monitor of the main control panel clearly shows the operating conditions of various devices without blurring. Therefore, by looking at the monitor, troubles occurring in various devices can be found early. Then, the cause of the trouble can be relatively easily found by repeatedly viewing the video recorded by the monitoring camera 14. Further, when it is difficult to visually find the cause of the trouble because the operating speeds of the various devices are high, the cause of the trouble can be effectively found by viewing the operating conditions of the various devices as a slow image.
Furthermore, since it is possible for an expert who is not in the field to see the shooting contents, it is possible to accurately find the cause of the trouble by asking the expert to make a decision. It also leads to labor saving of personnel involved in troubles occurring in the roving changer 4. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG.

In the present embodiment, a signal for synchronizing the operation of the roving changers 4, 4 is not sent via the CPU 20 of the carriage 3, and the CPUs 17, 18 of the roving changers 4, 4 are connected to each other. A big difference is that direct signal transfer is performed. In this embodiment, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different points will be described.

As shown in FIG. 3, C of each roving changer 4, 4
The PUs 17 and 18 can exchange signals with each other via the trolley wire without passing through the CPU 20 of the transport vehicle 3. L
The synchronous operation flag SA is stored in the memory 21 of the microcomputer MC built in the control device C1 of the roving changer 4 on the side.
LF is set. A synchronous operation flag SARF is set in the memory 22 of the microcomputer MC built in the control device C2 of the R-side roving changer 4.

When the L side roving changer 4 completes one cycle, the CPU 17 sends a work completion signal S1 to the R side roving changer 4.
Output to the CPU 18. When the R side roving yarn changer 4 completes one cycle, the CPU 18 outputs a work completion signal S2 to the CPU 17 of the L side roving yarn changer 4. When the CPU 17 inputs the work completion signal S2, the synchronous operation flag SALF is set to "1", and the CPU 18
Enters the work completion signal S1 and the flag SA for synchronous operation
The RF is set to "1". CPU1
Reference numeral 7 sequentially reads the synchronous operation flag SALF after a lapse of a predetermined time (time shorter than one cycle) from the start of each cycle, the synchronous operation flag SALF is set to "1", and the L-side roving changer Only when the roving change operation of No. 4 is completed, the L side roving changer 4 starts the next one cycle. Further, the CPU 18 sequentially reads the synchronous operation flag SARF after a lapse of a predetermined time (time shorter than one cycle) from the start of each cycle, and the synchronous operation flag SRF is read.
Only when the ARF is set to "1" and the roving changer 4 on the R side has completed the roving changer 4, the R side roving changer 4 starts the next cycle. Has become.

That is, when the carrier 3 comes into contact with the spinning frame 1 for roving replacement work, the monitoring cameras 14 and 14 are activated, and the roving replacers 4 and 4 are simultaneously moved from the carrier 3. It is launched. The roving changer 4 performs roving change work at the first stop position,
When the roving replacement work is completed, the CPUs 17 and 18 output work completion signals S1 and S2, respectively.

At this time, for example, when the roving changer 4 on the L side completes the roving changer operation before the roving changer 4 on the R side,
First, "1" is set only in the synchronous operation flag STRF of the memory 22, and the synchronous operation flag S of the memory 21 is set.
TLF is "0". At this point, the L side roving changer 4 has completed the roving change operation, but the synchronous operation flag STLF is set to "0", so CP
U17 does not cause the roving changer 4 on the L side to start the next one cycle but waits at the stop position. On the other hand, the R side roving changer 4
Then, although the synchronous operation flag STRF is set to "1", the roving replacement work is not completed, so the CPU
No. 18 does not start the next one cycle and continues the roving replacement work at the stop position. On the contrary, when the roving changer 4 on the R side completes the roving changer operation before the roving changer 4 on the L side, each CPU 17, 18 performs the next one cycle as described above. Do not start

Only after both roving changers 4 and 4 have completed the roving change operation, the synchronous operation flags SALF and SA.
Both RFs are set to "1", and the next one cycle can be started. That is, when the roving change operation is completed in the L-side roving changer 4, the synchronous operation flag SALF is issued.
Is set to "1", the roving changer 4 on the R side completes the roving change operation, and the synchronous operation flag SARF is set to "1". Since this state occurs simultaneously in both roving changers 4, the CPU 17,
18 causes the roving changers 4 and 4 to start the next one cycle almost at the same time.

In this way, the roving changers 4 and 4 are synchronously adjusted in each cycle and are always held in a state where they face each other. Therefore, the monitoring camera 14 can photograph the work situation of the roving changer 4 at the same predetermined place. As a result, the same effect as that of the first embodiment can be obtained. Furthermore, according to the present embodiment, it is possible to operate both roving changers 4 and 4 in synchronization without interposing the CPU 20 of the transport vehicle 3. Therefore, since the signal transmission / reception for the synchronous control is performed only between the CPUs 17 and 18 of the roving changers 4 and 4 without passing through the CPU 20, even when a trouble occurs in the CPU 20 of the transport vehicle 3, both roving yarns are transferred. This does not affect the synchronous operation of the exchanges 4 and 4.

The present invention is not limited to the above embodiments, but may be modified as follows without departing from the spirit of the invention. (1) In each of the above-described embodiments, the synchronization adjustment is performed for each cycle, but the interval and timing of the synchronization adjustment may be set appropriately. For example, the configuration may be such that synchronization adjustment is performed every plural cycles.

(2) A plurality of surveillance cameras 14 may be installed. Further, the position where the monitoring camera 14 is arranged can be appropriately set as long as the working situation of the roving changer 4 on the other side can be photographed. The surveillance camera 14 may not have a recording function or a zoom function.

(3) In the above embodiment, the monitoring camera 14
Was used for the purpose of early detection of troubles occurring in the roving yarn changer 4 and for finding the cause of the troubles, but the abnormal tendency of the tension state of the roving yarn due to the deviation of the operation timing of each operating part of the roving yarn changer 4 is seen. It may be used for preventive maintenance such as.

(4) In each of the above embodiments, both roving changers 4, 4
Although the two are held opposite to each other with the machine base 1 sandwiched therebetween, they may be synchronized with each other with a predetermined distance in the machine machine longitudinal direction. For example, the two may be offset by one cycle.

(5) In each of the above-described embodiments, when one roving changer 4 completes one cycle and then the other roving changer 4 does not complete one cycle even after a predetermined time elapses, an abnormality occurs. It is also possible to provide an abnormality determination means for determining as, and to notify the abnormality by a notification means such as a buzzer.

(6) In each of the above-mentioned embodiments, the two roving changers 4 and 4 are operated synchronously. However, if the two can be kept facing each other without being synchronized in the normal work, both of them will not necessarily be operated. It is not necessary to drive the two synchronously.

(7) Only when the displacement between the roving changers 4 and 4 is small, the angle of the monitoring camera 14 is automatically adjusted so that the predetermined location of the partner's automatic working machine is always photographed. The synchronous operation of the roving changers 4 and 4 may be omitted.

(8) In each of the above-described embodiments, the present invention is applied to the roving yarn changer 4 for performing the roving yarn changing operation on the spinning machine base 1, but other arrangements are provided on both sides of the spinning machine base. The present invention may be applied to an automatic work machine.

(9) As another embodiment, a waiting time may be set, and shooting of the surveillance camera 14 may be stopped if the partner's automatic working machine does not arrive due to trouble or the like even after the waiting time is exceeded. .

As described above in detail, according to the present invention, it is possible to photograph the working status of the other automatic working machine provided on the opposite side of the machine base by the monitoring camera installed in the automatic working machine. As a result, it has an excellent effect that the working status of the automatic working machine can be accurately seen. Further, claim 2
According to the invention described in (1), since the positional relationship at the time of working of both automatic working machines can be always the same, it is possible to reliably capture the working situation of the automatic working machine by the monitoring camera. Play.
