Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an mwr device for a traveling unit for detecting a yarn breakage state, and in particular, a device for driving and controlling a traveling unit for detecting a yarn breakage state of each spindle in a spinning machine such as a roving frame, a spinning machine, or a spinning machine. The knit drive device for thread-like tJJA detection is used.

2. Description of the Related Art Generally, it is known that it is necessary to detect yarn breakage during operation in spinning machines such as roving frames, spinning machines, and stretching and twisting machines. A self-propelled monitoring device (traveling unit), which uses the conventional yarn breakage detection method, is run along the direction in which each spindle of the spinning machine is arranged, and a photoelectric sensor installed in this monitoring device detects the optical It is used to detect Incidentally, the monitoring device detects the thread breakage state of each spindle while the machine is running, and issues a death notice to the operator when the thread breakage state is detected. After hearing the news of the death, the workers began work to restore the weight where the thread had broken.

However, because the conventional monitoring device described above automatically runs in a predetermined direction, it runs at a constant speed even when the operator is working to restore the weight where the thread broke. There was a problem that it caused harm to workers. Also,
Since this monitoring device runs continuously at a constant speed in a predetermined direction, the operator cannot freely stop and reverse the monitoring device. Furthermore, if this monitoring device arrives while the worker is in the process of restoring a weight with a broken thread, the worker must stop the work and resume the repair work after passing the monitoring device, which reduces work efficiency. There was also the problem that it worsened.

Therefore, the purpose of this invention is to ensure the safety of the worker who is working on recovering thread breakage, to enable the worker to freely stop or drive the machine at will, and to efficiently carry out the work to recover thread breakage. It is an object of the present invention to provide a driving device for a traveling unit for detecting a thread breakage state, which is improved to enable the detection of a thread breakage state.

In summary, the present invention is such that pushbutton switches are provided on both sides of the travel unit in the travel direction, and the stop or start of travel can be freely controlled by operating the pushbutton switches.

do.

Next, with reference to FIGS. 1 to 3, the MF 1+1 of the Tan 1hh machine 100 and the traveling unit 200 is looked at.
14.

As is well known, the spinning machine 5100 has weights provided at regular intervals along the longitudinal direction of the main body 110. Each weight is provided with a draft picker 120 for drawing the sliver and a spindle 133 for twisting the drawn thread and turning it into a pipe thread.

The pushbutton switches 231 and 232 are provided on both sides of the housing 201 in the running direction, and the button portions are formed relatively large so that the operator can easily operate them. Preferably, the height is selected so that the button portions of the push-button switches 231, 232 will hit the operator's arm or elbow when the operator is performing restoration work based on the broken thread state. When the travel unit 200 is traveling to the left, this push button switch 231 is pressed once to issue a stop command, and pressed a second time to issue a command to travel in the opposite direction. When the travel unit 200 is traveling to the right, the push button switch 232 issues a stop command when pressed the first time, and commands it to stop when pressed the second time.

41 is formed.

FIG. 4 is a circuit diagram of a regular drive control circuit of one embodiment of this starting J. Next, with reference to Figures 1 to 4,
The operation of this embodiment will be explained along with the specific circuit configuration shown in the figure.

(1) Normal driving operation In the normal state, all inputs of the OR gate 311 are at low level. Therefore, the OR gate 311 does not derive a high level prohibition condition detection output (that is, derives a low level signal).

Therefore, the low level high voltage of the OR gate 311 is inverted by the inverter 321 and
32 as one input. In addition, O
A case in which the R gate 311 detects a travel prohibition condition for any of the travel units 200 will be described in detail later.

By the way, the travel unit 200 travels from the out end OE to the gear end GE direction (to the left) when the travel drive motor 211 is rotating in the forward direction, and when the travel drive motor 211 is rotating in the reverse direction. When the vehicle is driven from the gear end toward the out end (that is, toward the right). Now, assuming that the traveling unit 200 is traveling to the left, a high level is derived from the RS flip-flop 341 or the set output terminal (Q), and the AND game) 3
It is given to 31. For this reason, AhJI) gate 3
31 gives a drive command signal to relay #351.

Accordingly, the relay circuit 351 supplies enough power to the travel drive motor 211 to cause it to rotate forward. In this state, when the traveling unit 200 reaches the gear end position, the front-mounted mid-switch 141 applies a high level signal to the input terminal 301. This high level signal is applied to monostable multi 361 via OR gates 312 and 313. Accordingly, the monostable multi 361 is
For example, a high level signal is derived for tIf: 2 seconds).

During the high level output time of this monostable multi 361, the direction of rotation of the motor 211 is hooked, and the direction of rotation of the motor 211 is sharply reversed.
It is created in enough time to give the state a smooth effect and prevent λ-lono. The output of this monostable multi 361 is the OIL gate 31
1 to the inverter 321. For this reason,
The inverter 321 is A during the output period of the monostable multi 361.
The ND gates 331 and 332 are disabled to stop the rotation of the motor 211. In addition, the OR gate 3
The output of 12 causes the 7 lip flop 341 to be reset. Therefore, the clip 70 knob 341 outputs a reset output (
A high level signal is derived from Q) and the AND gate 332
give to AND game 1-332 is monostable multi 36
After outputting 1 for a certain period of time, a drive command signal is given to the relay circuit 352.

In response, relay circuit 352 supplies electric power (ie, current of opposite polarity) to motor 211 for reverse rotation. As a result, the motor 211 is reversely rotated, and the traveling unit 200
drive to the right.

Then, when the travel unit 200 travels at the outside end position M, the limit switch 142 derives a high level signal and applies it to the input terminal 302.

This high level signal causes OIL gates 314 and 313
is applied to the monostable multi 361 via.

Therefore, the monostable multi 361 derives a high level signal for a certain period of time in the same manner as described above, and deactivates the AND gates 331 and 332. Also, the output of the OR gate 314 causes the 7-rip flon 1341 to be set. Therefore, the constant time r11 of the monostable multi 361
After 1 output, A N I) gate 331 connects to relay N path 35.
1 to drive the motor 211 in the forward direction. As a result, the regular traveling unit 200 is driven to travel leftward again.

As described above, in the passage 71 A-shape μ, the regular traveling unit 200 travels back and forth between the out end and the gear end.

(2) Operation when stopping during running If the traveling unit 200 approaches while restoring the broken thread of the weight, the operator should step over the pushbutton switch 231 on the side closest to him. 232.

The pushbutton switch 231'j* can be pressed by hand at the pressure L1 of 232, or if the operator sticks out his elbow in the direction in which the traveling unit 200 is coming, the pushbutton switch 231'j* can be pressed by hitting the elbow and being depressed. Derive the output to .

For example, assuming that the travel unit 200 is traveling to the left, the relay drive circuit 351 drives the motor 211 in the forward direction, and an output signal (high level) based on the pressure is transmitted to the OR Age-315, 312 and 313 to activate a monostable multi 361, and is applied to a binary 7 rip 70 amplifier (or binary counter) 371 via an OR gate 316. this binary 7
The limp 70 knob 371 derives a high level signal from the set output terminal when the first input is received from the O1i gate 316, and derives a low level signal from the set output terminal when the second input is received. be. That is, the binary 7 limp 70 limp 371 is the pushbutton switch 2
During the period from when either 31 or 232 is pressed once until the second suppression, a high level signal is continuously derived and the OR gate 311 and AND gate 3
33. Therefore, while the binary 7 lip-flop 3710 cent output (Q) is at a high level, the high level signal is applied to the inverter 321 via the OR'7'-) 311, inverted to a low level, and the AND gate 331 and 332 is deactivated. Therefore, since neither AND gates 331 and 332 derive a high level signal, relay circuits 351 and 352 stop supplying power to motor 211'. As a result, the traveling unit 200 stops traveling when either the pushbutton switch 231 or 232 is pressed once.

Next, if you want to make the traveling unit 200 run in the same direction after restoring the broken string of the bell, press a pushbutton switch (for example, d232) that is different from the pushbutton switch you pressed earlier. do. The press signal of this pushbutton input 232 is applied to the input terminal 304. The suppression signal of the pushbutton switch 232 is output from the OR gate 314.
The signal is set to the 7 flop flop 341 via the OR gate 316, and is applied to the binary 7 flop 371 via the OR gate 316. binary 7 rip 70 amp 37
1 sets the set output to low level in response to the second input from the 0 gate 316. In response, the OR gate 311 stops deriving the prohibition condition detection output (high level). Therefore, AND gate 331
is the cent output of Frimb 70 and Frimb 341 and inverter 3.
Based on the high level output of 21, a drive command signal is given to the relay circuit 351. Relay circuit 351 connects motor 21
Electric power having the polarity for forward rotation of the drive unit 200 is supplied to the motor 211, and the drive unit 200 starts running to the left.

On the other hand, if the operator wants to run the traveling unit (200) in the opposite direction to the direction in which it was traveling before stopping, the operator can press the same push button switch (200) to stop it.
31) and press 2 of this pushbutton switch 231.
The high level signal based on the second suppression is output to the OR gate 315.
and 312 to reset the 7 limb 70 knob 341.

At the same time, the binary 7 lip 70 block 371 is filled with 4 bits. In response, the binary 7 rip 70 tube 371 brings its output to a low level. Further, the output of the single-chamber constant multi-purpose multi-function 361 is set to low level L after a certain period of time after the pushbutton switch 231 is pressed. Therefore, AND gate 3
32 is the reset output of 7 lip 70 tube 341 and 01L
A drive command signal is given to the relay circuit 352 based on the fact that the low level low level B7 of the gate 3117>-A is inverted and given to a high level signal by the inverter 321.

Therefore, the relay circuit 352u supplies polar gravity to the motor 211 for reverse rotation. In this way, the traveling unit 200 is driven to travel in the opposite direction.

Note that the same operation is performed when the pushbutton switch 232 or t'1231 is pressed while the traveling unit 200 is traveling to the right.

If the pushbutton switch 231 straddles 232 is pressed and left as it is without performing the second suppression, the cent output of the binary counter 371 will be at a high level continuously, so the traveling unit 200 The stopped state is maintained for 5& or so.

Operation when storing and stopping the traveling unit 200 in the out-end position When storing and stopping the traveling unit 200 in the out-end position, press the return command pushbutton inch (Fig. A suppression signal (not shown) is input to the manual return command signal 011 via input terminal 305.
is applied to gate 317. In addition, the traveling unit 200
If the number of winding bases of a plurality of pipe threads 131 exceeds a specified amount while the machine is running, and it becomes necessary to change the girder pipe threads 131, the pipe threads 131 are automatically replaced by an autoton 7-a feature. , it is necessary to move the traveling unit 200 to the out-end position. Therefore, a predetermined period of time (for example, 5 minutes) before the autotoner mechanism operates, the storage command signal generated from the fixed unit 102 is applied to the OR gate 317 via the input terminal 306. This 01t gate 317 continuously derives a high level signal during a certain period of the storage command signal or return command signal and supplies it to the inverter 322.
, 335, and 336 as one input.

The inverter 322 inverts the high level signal to a low level signal and releases the reset state of the flip-flop 342. This causes the 7-rip 70 amplifier 342 to wait for a set input to be applied.

By the way, when IjrJK Self OR Goo 1-317 or High Level Haku is derived and the traveling unit) 200 is commanded to be stored, if the traveling unit is traveling to the left, does it need to be stopped once and then reversed? . In this case, AND gate 336 provides an activation command signal to monostable multi 362 based on the fact that both the output of 01L gate 317 and the output of flip-flop 341 are at a high level. Accordingly, the monostable multi 362 derives the ill high level signal of the song at a certain time and outputs the illumination signal to the OIT gates 315, 312,
Monostable multi 361 is activated via 313. During the high level output period of the monostable multi 361, the output of the OR gate 311 is high level, so A, N
D-gates 331 and 332 are activated and thus motor 211 is stopped. At the same time,
The output of monostable multi 361 is OR game) 315, 312
The 7-lip flop 341 is reset via the 7-lip flop 341. Therefore, after the monostable multi 361 outputs for a certain period of time, AND
Gate 332 drives relay circuit 352. Therefore, in relay cycle 11, 352 reverses the motor 211 and causes the traveling unit 200 to travel in the outer end direction.

Then, when the traveling unit 200 travels at the out-end position and is stored in the j-r constant position, the limit switch 142 derives an output and applies it to the input terminal 302. The output of this limit switch 142 is the OIL gate 314.
The clip 70 knob 341 is sent to the clip 70 through the AΔD gate 335. Accordingly, AND
The gate 335 detects that the travel unit 200 is stored at a predetermined position at the out end based on the presence of the storage command signal and the output of the limit switch 142, and sets the clip 70 knob 342. -ru. The cent output (high level) of this flip 7'Cl tube 342 is sent to the inverter 32 via the 0'R gate 311.
1, is inverted to a low level signal by an inverter 321, and is applied to AND gates 331:332. Therefore, relay circuits 351 and 352 are connected to motor 211.
Do not rotate. In this way, the traveling unit 200
is stored in place at the out end.The next condition is OJ
This continues while the output of the t-gate 317 is at a high level.

Then, when the autoton 7-a mechanical thread 131 is replaced, the output of the R gate 317 becomes low level.

Therefore, the inverter 322 inverts the low level signal to a high level signal, resets the 7 limp 70 knob 342, and releases the travel inhibited state through the O1L gate 311 and the inverter 321. As a result, the traveling unit 200 travels to the left again based on the neutral state VC of the flip 70 knob 341.

Note that if the output of the OIL gate 317 becomes high level while the traveling unit 200 is stopped based on the pressing of the pushbutton switch 231 or 232, the traveling unit 200 is stopped as follows regardless of the stop command.
The out-end position is the binary flip-flop 371
When the set output of l) and OR gate 317
When the output of is at a high level, an operation command signal is given to the monostable multi 363 based on 7. The monostable multi 363 derives a high level signal after a certain time delay, and the gate 3
15 and 312 to reset the 7 rib 7 p knob 341. As a result, the traveling unit 200 is driven to travel rightward.

Operation in case of emergency stop If you want to make the traveling unit 200 come to an emergency stop due to some kind of abnormality, it can be done manually by the operator or by an abnormality detection circuit (not shown) included in the fixed unit 102. An emergency stop signal is derived.

This emergency stop signal is connected to input terminal 307 and OR gate 3.
11 to the inverter 321. Therefore, the inverter 321 derives a low level signal and performs an AND
Gates 331 and 332 are deactivated. As a result, the relay circuits 351 and 352 immediately stop supplying power to the motor 211, causing the traveling unit 200 to come to an emergency stop. When both outputs (4) become high level signals, bipolar currents are simultaneously supplied to the motor 211, which may cause the motor 211 to burn out. Therefore, in this case, AND gate 33
4 detects that the set output and reset output of the 7 lip 70 knob 341 are at a high level, and the I\
The illegal signal is derived and applied to the OR gate 311. Also in this case, the output of the OR gate 311 becomes high level, and the power supply to the motor 211 is stopped. This has the advantage that the device 211 can be protected.

As described above, according to the present invention, the traveling unit that detects yarn breakage while traveling near the spinning machine can be freely stopped at a desired position by human operation.
It is possible to prevent the travel unit from colliding with a worker who is working to restore a broken thread, thereby preventing the worker from being harmed, and the unique effects of being able to manage the broken thread extremely safely. Another advantage is that the traveling unit can be easily and quickly stopped and the traveling direction can be changed.
