JPS5836222A - Driving method for tandem card - Google Patents

Abstract

PURPOSE:The rotation of the motor for doffer, which drives the first, second doffers and the feeder, is controlled so as to follow up the rotation of the first and second motors at the start and stopping to reduce the disturbance of webs and the weight deviation of slivers during the operation. CONSTITUTION:The first doffer 10 and the second one 14 in the first card and the second one 1, 2 are driven by the motors for doffers IM3 and IM4. These motors for doffers or their gear mechanisms are controlled, at their start, so as to follow up the rotation of the slower accelerated motor of either IM1 or IM2 and at the spopping, so as to follow up the faster deceleration. Thus, the start and complete stop of the doffers 10, 14 is almost completely synchronized with the start and the complete stop of the motors IM1 and IM2.

Description

[Detailed Description of the Invention] O″eT regarding the driving method of Honjitsu W Hiro tandem card
oru.

For tandem cards, the first and second cards
11. It is important to synchronize the start and stop of the second cylinder, so that there is a large difference in the time between the first and second cylinders r-ox at the time of start-up. When the 111th cylinder reaches the positive electric number faster than the 2nd cylinder,
The thickness of the web in the second cylinder becomes large and the cardin 1 action cannot be performed sufficiently (the quality of the spun sliver deteriorates). If the first cylinder is stopped earlier than the second cylinder due to a large discrepancy in the time, a web break will occur between the first and second cylinders, and sliver splicing will be required at the next start-up. This results in a decrease in the operating rate and waste of raw materials (sliver unevenness occurs).Therefore, in order to solve the above problems, 1.
Cylinder and first take-in! The second cylinder of the second card and the second tracker are driven by the second motor, and other driving parts such as the 1.112 dolphers of the first and second cars F, i.e. the feed 1L. A variable speed motor is used to drive each of the totsunsu 7's outer part, stripping part, and part of the coiler (hereinafter also referred to as the first, second part, etc.), and a timer is used to start and stop the variable speed motors. A tandem card driving method has been proposed in which the starting and stopping of the first and second motors are synchronized by Start and stop using Tie!-III JP AO5S
-36222 (2), synchronized with the start and stop of the second motor), the time it takes for the first and second cylinders to reach the normal rotation speed when starting and the time it takes for them to come to a complete stop when stopping is Of the belt! Due to fluctuations in the load applied to the first and second cylinders due to the condition of the I-shape and the presence or absence of webs, etc.
It is extremely difficult to set the correct time for one hour, and I may have to change the set time again and again to get it to 1 - it's so annoying.
Moreover, if the time setting of this timer is not accurate, the rotation and stop of the first and second cylinders will not be synchronized with the rotation and stop of the first and second cylinders. There was a similar layer between the cylinder and buildings 1, 2, etc. that caused a web break during web access. t, as above O, the first
The variable speed motor automatically starts plowing after a predetermined set time has elapsed after starting the second motor, so if there is any problem such as the bend slipping due to bend clogging or belt coming off, etc. [1111e] Even though the first and s2 motor drive systems rotated normally and were running at C%/h, there was a problem that the first and second motors were activated intermittently, causing web visits. O Therefore, the present invention aims to solve the above problems,
Even if the method is such that the first and second dosing ports, feeding parts, etc. are driven by the first and second motors for driving the first and second cylinders and a separate dosing motor, The rotation at the time of starting and stopping of the dispenser is controlled to follow the rotation of the first and second motor drive systems, and the rotation start and complete stop of the first and second dispensers is controlled by the rotation start and complete stop of the first and second motor drive systems. It can be almost synchronized with the stop, improving the quality of the spun sliver and improving work efficiency! i! ! The purpose of this invention is to provide a method for driving a tandem card that is as easy as possible.

2nd Teikain-ra 8.12 is logic-transition and 1-), and the KWj1 rotation speed gradually decreases, and the speed of KWj1 decreases again. By opening the lO opening contact Tl-41, the first and second converters 10, 14, etc. are switched to the low-speed circuit.
, the second data input terminal 120, whichever has the faster rate of decrease, starts to decrease as much as the 11 rotation speed at the above point (・), and the voltage at the 42A control terminal 411D also decreases to 0. The voltage input to the terminal 45 of the inverter device zyv decreases according to the deceleration of the second data input 120, which is faster, and as a result, the rotational speed of the third and fourth motors 5.1M4 decreases. is lowered, and the rotational speed of the first and second transfers 10.14, etc. is reduced.

When the rotational speed of the second cylinder 11 becomes less than P2O-rotational speed at the time of (-), the voltage at the terminal 450 of the inverter device V becomes less than the lowest frequency unfollowable voltage indicated as the set voltage, and the inverter device The output of the 1M force becomes non-voltage, the driving of the third and fourth motors xM5 and l114e is stopped, and the rotation of the first and second cylinders 10, 14, etc. O11 is completely stopped. The force input ν-rough 2 etc. is completely stopped at the time of its t& value (-) after a delay, and then at the time (o) 0, the first cylinder 10 and the first day force input a - JP-A-8358-36222 (7) The rotation of Te 8 is completely stopped. 11th 2nd as above
The rotation of the dotuhua 10.14 etc. is the first and second cylinder 7.
．． Since the complete stop is made immediately before the complete stop of No. 11, etc., web breakage at the time of stopping is reliably prevented. In addition, the above first and second cylinders 10% 11 etc. are inverter equipment x
By vt1c, it is always synchronized and completely stopped almost simultaneously,
Web clutter is prevented.

In the above embodiment, the dosing motor is
III* by two motors, the second speed and the fourth motor
However, it can be configured with one motor to transmit the rotational force of the first converter to the second converter, or it can be configured with five or more motors to transmit the rotational force of the first converter to the second converter. It is also possible to drive part of the coiler with a separate motor.
The other driving parts such as the second docker motor are driven directly by the doffer motor, but they are configured to be driven by the doffer motor through a variable speed. The gear ratio may be controlled to follow the rotation of the Kd first and second motor drive systems that are slower to accelerate when starting, and to the rotation that is faster to decelerate when stopped. The device may be a glossy or contact type device that is arranged to detect rotating parts other than the first and second taker sheets, for example, the rotational speed of the first and second cylinders Oa. Although the speed of the motor is changed by changing the frequency using an inverter device, it is also possible to change the speed by other methods such as voltage control. 1st cylinder, 1st day in-fielder and 17th rat.
The second cylinder, the second taker-in roller, and the 27th ratchet of the second card are moved by the second motor to the first and second cylinders of the second card.
Card jlldl! Since the other drive parts such as the two-way puller are driven by the two-way mover motors, either directly or through variable speed, the loads applied to the first and second motor drive systems can be made approximately equal. 1. The start-up time and rotation stop time of the second cylinder can be easily synchronized, and the rotation speed of the first and second cylinders can be changed even if the rotation speed of the first and second cylinders fluctuates. Since the machine can always maintain a predetermined speed even when the machine is spinning, it is possible to reduce web disturbances and sliver weight fluctuations during operation, thereby improving the quality of the spun sliver. Even in the above-described driving method in which the first and second transfer motors are driven by separate transfer motors from the first and second motors, the drive of the transfer motors or the connecting switch is started. At times, the rotation of the first and second motor drive systems is slow, and when stopped, the speed is reduced to 01.
1. The rotation of one of the rotations is controlled to follow each other, and when the rotation speed of the slow one of the first and second drive systems reaches the set speed or more, the doffer motor or the speed change mode is started, and the first and second When the motor drive system decelerates faster (6 rotational speed - IIXv) or lower than the constant speed, the doffer motor and the O drive are stopped. Immediately after the rotation of the 2nd cylinder starts, the % and 1st and 2nd
The complete stop of the spinning sliver can be reliably carried out just before the first and second cylinders are completely stopped, thereby making it possible to prevent web clogging and web breakage that occur during starting A27 and stopping, thereby improving the quality of the spun sliver. It is possible to improve work efficiency. In addition, as mentioned above, since we started the transfer motor or transmission after checking the rotation of the first and second motor drive systems, some kind of OA problem may occur in the first and second motor drive systems. Even if the rotation of the first and second motor drive systems is stopped, damage to clothing etc. due to web jamming and generation of sparks can be prevented.

Furthermore, even if the driving method is such that the starting and stopping of the first and second transfer cylinders are synchronized with the starting and stopping of the first and second cylinders as described above, the synchronization is not possible unless the transfer motor or the control is controlled. Since the drive of the linked machines was controlled to follow the rotation of the first and second motor drive systems that are slow to increase speed when starting up, and to follow the rotation of the first and second motor drive systems that are faster to decelerate when stopped, the first, The driving mechanism between the -2 dolpher and the first and second cylinders can be greatly simplified, and this has the effect of being able to be implemented at a low cost.
