然后，打开定时调整电路61随时间连续使其输出电压下降，在工序III的中途(漏极电压的增减变化期间Tv的中途)的切换定时进行变化以使得变为上述栅极阈值电压以下。
Then, the turn-ON timing adjustment circuit 61 continuously decreases the output voltage over time, and at the switching timing during step III (during the increase-decrease change period Tv of the drain voltage), changes the output voltage to equal to or less than the gate threshold voltage.
此外，由于打开增速控制用MOSFET 41是P沟道型，因此打开定时调整电路61的输出电压将+Vcc电位以基准示出。
It is to be noted that the turn-ON speed-increase control MOSFET 41 is a P-channel MOSFET, and thus the output voltage of the turn-ON timing adjustment circuit 61 is indicated on a +Vcc-potential basis.
另外，在通电检测部7正检测主电路中的主电流的增加状态的期间，即，在仅仅在漏极电流正增加的工序II的期间，通电切换电路81作为电流检测信号而输出与电流变化量对应的预定的电压(上述理由中用负电位图示)。
While the conduction detection device 7 is detecting an increase state of the main current in the main circuit, that is, during step II, which is when the drain current increases, the conduction switch circuit 81 outputs, as a current detection signal, a predetermined voltage that is based on the amount of current change (the above-described reason, the current detection signal is indicated as negative potential).
此处，各增速控制用MOSFET 41、42的半导体开关元件在其栅极电压低于该元件特有的栅极阈值电压的情况下，源极端子S1、S2与漏极端子D1、D2之间成为切断状态。
In this respect, when the gate voltage of each of the semiconductor switching elements of the speed-increase control MOSFETs 41 and 42 is lower than a gate threshold voltage unique to the element, the state between the source terminal S 1 and the drain terminal D 1 and the state between the source terminal S 2 the drain terminal D 2 are in non-conduction state.
另外，在栅极电压高于栅极阈值电压的情况下，根据其电压超过量，源极端子S1、S2与漏极端子D1、D2之间的通电量会增大。
When the gate voltage is higher than the gate threshold voltage, the conduction amount between the source terminal S 1 and the drain terminal D 1 and the conduction amount between the source terminal S 2 and the drain terminal D 2 increase by an amount equivalent to the amount by which the gate voltage is higher than the gate threshold voltage.
这样各增速控制用MOSFET 41、42的半导体开关元件具有并列持有开关功能和通电量的调整功能的控制特性。
Thus, each of the semiconductor switching elements of the speed-increase control MOSFETs 41 and 42 has control characteristics represented by a switching function and a function of adjusting the amount of conduction.
并且，该打开控制时的增速控制是指进行如下操作：打开增速控制用MOSFET 41是否针对主电路MOSFET 100的栅极端子Gm增加电流以大于从栅极电阻31流入的电流。
In the speed-increase control in the case of the turn-ON control, the turn-ON speed-increase control MOSFET 41 operates to determine whether to increase the current flowing from the gate resistor 31 into the gate terminal Gm of the main circuit MOSFET 100.
通过针对这样的控制特性的打开增速控制用MOSFET 41施加如上所述那样增减变化的栅极电压，在打开序列中的各工序I～IV中分别进行所对应的增速控制。
By applying the gate voltage that is increase-decrease changeable in the above-described manner to the turn-ON speed-increase control MOSFET 41 having the above-described control characteristics, speed-increase controls corresponding to respective steps I to IV in the turn-ON sequence are performed.

本发明涉及纺织环锭纺纱机。
The present invention relates to textile ring spinning machines.
具体地，本发明涉及用于环锭纺纱机中的自动纱线接头单元的纱线抽吸装置。
Particularly, the invention relates to yarn suction arrangement for an automatic yarn piecing unit in ring spinning machines.
更具体地，本发明涉及断纱拾取装置，以使断纱端部与纺纱纬管(spinning cop)分离，从而能够在纺织环锭纺纱机中进行自动接头操作。
More particularly, the invention relates to broken yarn picking arrangement to detach the broken yarn end from the spinning cop to enable automatic piecing operation in textile ring spinning machines.
环锭纺纱机是纺织纺纱厂中的最终的纱线生产机，这是非常关键的机器。
Ring spinning machines are the final yarn producing machines in textile spinning mills, which are very crucial machines.
所述环锭纺纱机在纺纱流程中产生最终形式的棉花，即，所谓的纱线。
The said ring spinning machines produces the resultant form of cotton in spinning line, so called yarn.
在环锭纺纱机中经常发生的纱线断裂是纺纱工业在世界范围内所面临的主要问题。
Yarn breakage occurs frequently in ring spinning machines which is a major setback spinning industry is facing worldwide.
必须连续监测纱线断裂，并且断纱必须由工人立即进行接头。
Yarn breakage has to be continuously monitored and broken yarn has to be pieced then and there by the workers.
纱线断裂是由于纱线和机器的各种参数导致的，并且是不可避免的。
The yarn breakage occurs due to various parameters of yarn and machine and it is unavoidable.
在长的细纱机站中，人工连续监测纱线断裂并沿着环锭细纱机的路径行进全天候地对断纱进行手动接头。
In long spinning frame sites, human labours continuously monitor yarn breakages and perform manual piecing of broken yarns round the clock walking along the pathways of the ring frames.
在断纱的成功接头之后，然后必须重新开始纱线纺纱程序(以及因此，每个断纱的纱锭)，以免浪费纱线。
This has to be done for a machine frame normally consisting of more than 1600 spindles and about 75 metres long. After successful piecing of broken yarn, yarn spinning sequence has to be restarted then and there for every broken yarn spindles, in order to avoid wastage of yarn.
为了克服上述问题，正在开发自动接头单元。
To overcome above problems, automatic piecing units are being developed.
自动接头单元为具有引导设备的可移动车辆的形式。

Then the broken yarn end which is available in the spinning cop has to be found and detached from the cop and lifted above to enable piecing operation.
纱线从纺纱纬管的所述自动分离通常是非常困难的任务。
The said detaching of yarn from spinning cop automatically is a very difficult task in general.
为了在纺织纺纱机中成功地实现自动接头单元，过去几年进行了广泛的试验。
Extensive trials are being done for past several years to successfully implement automatic piecing units in textile spinning machines.
但至今为止，由于所涉及的困难，自动接头装置仍未实现。

在试验中的现有的接头装置中，自动接头单元沿着环锭纺纱机的通道纵向移动。
In the existing piecing arrangements which were on trials, the automatic piecing unit moves longitudinally along the aisle of the ring spinning machine.
环锭纺纱机能够将纱线卷绕到安装于纺纱纱锭的线筒上，即，所谓的纬管。
The ring spinning machine is capable of winding yarn onto a bobbin mounted to spinning spindle, so called cop.
当在纺纱程序中发生纱线断裂时，断纱丝缠结在纺纱纬管中。
When yarn breakage occurs in the spinning sequence, the broken yarn thread becomes entangled in the spinning cop.
为了能够对纱线进行接头，必须将缠结的纱线端部从纬管分离。
To enable yarn piecing, the entangled yarn end has to be detached from the cop.
为了从纬管拾取断纱端部，自动接头单元通常设置有抽吸装置。
For picking the broken yarn end from the cop, automatic piecing units are normally provided with suction arrangements.
具有嘴/开口的柱形抽吸喷嘴从接头单元延伸，并通常定位于纺纱纬管的顶部上方的预定距离处，以从纬管抽吸纱线端部。
The cylindrical suction nozzle with mouth / opening extends from the piecing unit and is positioned usually at a predetermined distance above the top of the spinning cop to suck the yarn end from the cop.
为了提供所需的抽吸，通常使用抽吸马达。
For providing the required suction, normally suction motors are used.
现有的抽吸马达尺寸大并且昂贵。
The existing suction motors are large in size and expensive.
此外，由于其尺寸，抽吸马达在自动接头单元中占据相当大的空间。
Also, suction motor occupies considerable space in automatic piecing unit due to its size.
除了增加成本之外，这还导致自动接头单元的质量增加。
This results in increased mass of the automatic piecing unit in addition to increased cost.
需要开发一种改进的从纬管拾取断纱的方法，其缓和了自动接头单元的空间和成本，本发明对此提供了一种解决方案。
There exists a need to develop an improved broken yarn picking from the cop which compromises both space and cost of the automatic piecing unit, to which the present invention provides a solution.
本发明提供了一种用于从纺纱纬管拾取断纱端部的改进的装置，以能够在环锭纺纱机中自动接头。
