DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of operating a streamline machine, and particularly relates to a method of operating a streamline machine that automatically switches from low-speed operation to high-speed operation in a streamline machine that performs low-speed and high-speed operations. be.

Recent streamline machines use feed rollers,
Doffer, Shuto Roller, Calendar Roller of Koira Department, etc. (
A high-speed streamline machine (generally referred to as a high-speed card) in which the number of revolutions of a doffer (hereinafter referred to as a doffer, feed roller, etc.) is increased has been manufactured and is widely used.

With this high-speed card, the operator performs low-speed operation by pressing the low-speed entry pushbutton switch at startup, and after performing the so-called kissing operation of gathering the web peeled off from the doffer and inserting it into the trumpet, the operator presses the high-speed entry pushbutton switch. Press to switch to high-speed operation and perform high-speed operation.

If an abnormality that causes damage to the machine, such as double wrapping in the wrap supply section, curling of the doffer section, or wrapping of the calender roller section, occurs during high-speed operation, a signal from the abnormality detection device will cause the unit to Operation is stopped immediately to prevent damage to the machine base. In addition, if there is an abnormality that does not cause damage to the machine but should be corrected immediately, such as when there is not enough plastic wrap remaining, when the can becomes full, or when the sliver is cut, this abnormality detection device is used. The signal switches from high-speed operation to low-speed operation. In the above, if the cause of the abnormality is resolved while the machine is stopped,
The operator presses the low-speed on-off pushbutton switch again, then presses the high-onput pushbutton switch to switch to high-speed operation, and if the cause of the abnormality is resolved during low-speed operation, presses the high-onput pushbutton switch again to switch to high-speed operation. I was switching to
However, in such a high-speed card, the operator performs a switching operation from low-speed operation to high-speed operation by pressing a button, and sometimes forgets to switch to high-speed operation.

If this task of switching to high-speed operation was forgotten, the benefits of the high-speed card would not be realized at all, resulting in a drastic reduction in the amount of production that could have been produced, resulting in extremely large losses. The present invention solves the problem caused by the operator forgetting to perform the switching operation, and provides a card operating method that automatically switches from low-speed operation to high-speed operation after eliminating the cause of the abnormality. The purpose is to

Therefore, while the drive motor 2 is rotating, the cylinder 3, taker roller 4, and fly comb shaft 11 are always rotating, and the doffer 5, feed roller 6, etc. after the electromagnetic clutch 9 turn the electromagnetic clutch 9 ON and OFF. By doing so, the driving force of the drive motor 2 is transmitted, disconnected, and controlled.Then, the electromagnetic clutch 9 is
If F is applied, the feeder 5, feed roller 6, etc. will stop rapidly without actively applying braking due to the resistance and small mass of each gear train. Next, the electric circuit diagram shown in FIG. 2 will be explained. In this circuit diagram, first to twelfth circuits are connected between power lines L and L, and the first circuit includes a push button switch PB1 for starting the drive motor 2 and a push button switch PB2 for stopping the drive motor 2. , and the excitation coil MSI of the electromagnetic switch for the drive motor. Then, the normal contact MS1a of the excitation coil MSI is connected to the second
It is connected in parallel to the activation pushbutton switch PBI in the circuit, and is also connected to the eighth circuit. Further, a normally closed contact MS1b is connected to the fourth circuit. The third circuit includes a switch PBI' that interlocks with the starting pushbutton switch PBI, and a cleaning blower motor (
An excitation coil MS2 of an electromagnetic switch (not shown) is connected. And the normally open contact MS2a of the excitation coil MS2
is connected in parallel to the switch PBI' in a fourth circuit. The first timer TRI is connected to the fourth circuit, and its normally closed contact TR1b is connected to the third circuit.
The fifth circuit includes a doffer stop push button switch PB3,
Low-speed ON pushbutton switch PB4 and first relay CRI
But it is connected.

The normally open contact CR1a of the first relay CRI is connected in parallel to the low-speed ON pushbutton switch PB4 in the sixth circuit, and is also connected in series to the eighth circuit and the twelfth circuit. A second timer TR2 is connected to the seventh circuit as a timer that operates simultaneously with the resolution of the abnormal signal, and its normally enabled point TR2a is connected to the tenth circuit. The eighth circuit includes a switch PB turtle' that moves with the low-speed input pushbutton switch PB4, and a high-speed input pushbutton switch PB.
5 and a second relay CR2 follow, the normally open contact CR2a of the second relay being connected in parallel to the high distance entry pushbutton switch PB5 in the ninth circuit, and the first
It is also connected to the 1-1 circuit. Also, normally closed contact CR2b
is connected to the 6th circuit and the 11-2nd circuit. A pilot motor PM that changes the gear ratio of the variable transmission 8 is connected to the eleventh circuit.

Further, to the 11th circuit, L and LSH are connected to the IJ mit switch for setting the low speed limit and high speed limit of the gear ratio of the variable transmission 8, and when the low speed limit is reached, the mit switch L opens and the high speed limit is set. When the limit is reached, a mitt switch LSH opens to stop the pilot motor PM. Further, an exciting coil MC for operating the electromagnetic clutch 9 is connected to the twelfth circuit. Note that the normally closed contact CR3b connected to the fifth circuit is detected by an abnormality detection device (not shown) to detect abnormalities that may cause damage to the machine, such as double wrapping in the wrap supply section, curling up in the doffer section, and This is a contact that is activated to open the circuit in the event that the roller becomes entwined.

Also, a normally open contact C connected to the seventh circuit and the eighth circuit
R4b is a contact that is actuated to open the circuit when the can is full when the amount of lap supply is low.
Additionally, the normally open contact CR5b connected to the fifth and seventh circuits is a contact that is actuated to open the circuit if the sliver breaks. Next, the concrete operation of the circuit diagram connected in this way will be sequentially explained in accordance with the actual operation.

■ Now, if you press the starting pushbutton switch PBI of the first circuit, the excitation coils MS1 and MS2 will be excited and the drive motor will start.
2 and the blower motor starts. By starting the blower motor, the machine becomes ready to remove fluff generated in various parts of the machine, and as the drive motor 2 starts, the cylinder 3 and take-in roller 4 start rotating. Also,
This state is maintained by the normally open contact MS1a of the second circuit and the normally open contact MS2a of the fourth circuit. Furthermore, by opening the normally open contact MS2a, if the variable transmission 8
If the gear ratio of the variable transmission 8 is not at the low speed limit on the low speed side, the pilot motor PM rotates in the reverse direction and shifts the gear ratio of the variable transmission 8 to the low speed side. When the low speed limit is reached, the limit switch L is mechanically turned OFF and the pilot motor PM
stop rotating. ■ When the low-speed ON pushbutton switch PB4 of the 5th circuit is pressed from this state, the 1st relay CRI is energized, self-retained by the normally open contact CR1a of the 6th circuit, and the normally open twill point CR1a of the 12th circuit is activated. Since it is closed, the exciting coil MC is excited and the electromagnetic clutch 9 is connected.

As a result, the driving force transmitted from the take-in roller 4 is transmitted to the variable transmission 8 and the electromagnetic clutch 9, which are set at the lowest speed ratio.
is transmitted to the doffer 5, feed roller 6, etc. via
The printer 5, feed roller 6, etc. are rotated at low speed, and the card is placed in a low speed operating state. ■ Furthermore, from this state
When the high-speed ON pushbutton switch PB5 of the circuit is pressed, the second relay CR2 is energized, and due to the energization of the second relay CR2, the normally open contact CR2a of the 9th circuit is closed and self-holding, and the "11-1 circuit Normally open contact CR2a closes,
The normally open contact CR2b of the 11-2 circuit will open,
Pilot motor PM begins to rotate forward.

As a result, the gear ratio of the variable transmission 8 slowly shifts to the high speed side, and the rotational speed of the doffer 5, feed roller 6, etc. gradually increases. Then, when the gear ratio shifts to the highest speed side, the limit switch LSH is mechanically turned OFF.
Stop the rotation of pilot motor PM. Further, when the gear ratio shifts to the high speed side, the lj mitt switch L returns to the state shown in the figure. The time required to shift the gear ratio from the lowest speed side to the highest speed side is set to be relatively long in order to prevent fluctuations in the weave amount due to time delays in the fiber transport system.
Specifically, it is set to about 3 Kagami Akira. (2) Next, the case where one cycle of combined operation is completed will be explained. The drive motor 2 is stopped by pressing the stop push button switch PB2 of the first circuit, and by pressing the stop push button switch PB2, the excitation coil MSI of the first circuit is also de-energized and the drive motor 2 is stopped. Motor 2, cylinder 3
, take-in roller 4, dotshua 5, feed roller 6
etc., stops after approximately 6 to 10 minutes of inertia rotation with the electromagnetic clutch 9 connected. Also, by releasing the excitation of the excitation coil MPI, the normally closed contact MS1 of the fourth circuit
b is closed, the first timer TRI of the fourth circuit starts counting. Note that the setting time of the first timer TRI is
It is set to be the same as or slightly longer than the inertia rotation time (6 minutes to 1 minute) of the drive motor 2, etc. mentioned above, and when the first timer TRI times out, the normally closed contact of the third circuit TR1b is opened, the excitation coil MS2 of the third circuit is de-energized and its normally open contact MS2a is opened, the first relay CRI of the fifth circuit is de-energized and its normally open contact of the first phantom circuit is opened. CR1a opens, the electromagnetic clutch 9 is disconnected, and the propeller motor also stops. Therefore, the stop pushbutton switch PB of the first circuit
By pressing 2, the drive motor 2, cylinder 3, take-in roller 4, dower 5, feed roller 6, etc.
With the electromagnetic clutch 9 connected, it will stop after inertia rotation for about 6 to 10 minutes, and the electromagnetic clutch 9 will be disconnected at the same time as the stop, or after a slight delay. ■ Next, the operation when an abnormality occurs during the above-mentioned normal operation will be explained.

As mentioned above, the normally closed contact CR3b of the fifth circuit is connected to abnormalities that may cause damage to the machine (double wrap in the supply section,
When winding up at the dotted part, winding up at the calendar roller part, etc.) occurs, the first relay C of the fifth circuit
RI is de-energized and the 12th circuit connects its normally open contact CR1a.
It operates to open and disconnect the electromagnetic clutch 9.
Therefore, regardless of whether the machine is in a low-speed or high-speed operating state, the printer 5, feed roller 6, etc. are stopped suddenly to prevent damage to the machine. In addition, the normally closed contact CR4b connected to the 7th circuit and the 8th circuit operates when the amount of supply lap is low or when the can is full, and if this condition occurs during high-speed operation, the 8th circuit The excitation coil CR2 of the circuit is de-energized, the normally open contact CR2a of the 11-1 circuit and the normally closed contact CR2b of the 11-2 circuit are switched, and the pilot motor PM is reversed ~ variable transmission 8
Shift the gear ratio to the low speed side to make the machine run at low speed. The operator then supplies the wrap and the L during low-speed operation.
Perform work such as exchanging full key cans and empty key cans. Furthermore, the normally closed contact CR5b connected to the fifth circuit and the seventh circuit operates to open the circuit when the sliver breaks, and if the sliver breaks during high-speed operation, the normally closed contact CR5b of the fifth circuit operates to open the circuit when the sliver breaks. The relay CRI is deenergized, the electromagnetic clutch 9 is disconnected, and the printer 5, feed roller 6, etc. are stopped. (2) Next, the operation after eliminating the cause of the abnormality, which is the subject of the present invention, will be explained.

First, when the normally closed contact CR3b is activated and the doffer 5, feed roller 6, etc. are stopped, the double wrap in the supply section,
If you eliminate the cause of the abnormality, such as winding up at the doffer section or winding at the calendar roller section, and press the low speed on push button switch PB4, the high speed on push button switch PB can be activated.
Even if you do not press 5, it will automatically shift to high-speed operation after a certain period of time. That is, if the low-speed ON pushbutton switch PB4 is pressed after eliminating the cause of the abnormality, the first relay CRI of the fifth circuit is energized and starts low-speed operation as in the normal operation described above, and at the same time, the seventh circuit is activated. The second timer TR2 is energized, and after a certain period of time the second timer TR2 times out, the normally open contact TR2a of the 10th circuit is closed, and the second relay CR2 of the 8th circuit is energized, causing the doffer 5, feed roller 6, etc. to move at high speed. be driven. In addition, if the normally closed contact CR4b is activated, if the operator corrects the cause of the abnormality by supplying plastic wrap or replacing the full can with the empty can, the dolphin 5, feed loaf 6, etc. will remain open for a certain period of time. Automatically shifts from low-speed operation to high-speed operation.

That is, by eliminating the cause of the abnormality, the second tire TR2 of the 7th circuit starts counting, and the second timer TR2 starts counting.
After the second time-up, high-speed operation is started in the same manner as described above. Furthermore, ``If the normally closed contact CR5b is activated, the operator should first press the low-speed ON pushbutton switch PB4 to spin the sliver, and then resolve the cause of the abnormality by connecting the spun sliver end and the cut sliver end. , the card is automatically shifted to high-speed operation after the second timer TR2 times out, as described above.

Note that if the sliver is cut during low-speed operation, the operator simply connects the sliver and the operation is automatically shifted to high-speed operation in the same manner as described above. It is configured as above,
In the present invention, when the cause of the abnormality is eliminated, the timer starts counting, and when the timer times out, the card automatically shifts from low-speed operation to high-speed operation. This has the effect of preventing a drastic decrease in the production amount that should be possible for full-size kettle production due to forgetting to press the on-press button switch.

Furthermore, since the operator shifts from low-speed operation to high-speed operation after a certain period of time after eliminating the cause of the abnormality, the operator can safely perform the work to eliminate the cause of the abnormality.
