Analysis of the Regularity of Assigning Shuttles of Multiple Box Looms;
多梭箱织机梭子调配规律分析
To move the shuttle box up and down in order to bring the right shuttle to the picking level, a box motion is used.
梭箱机构可将梭箱上下移动,将需要的梭子移动到投梭位置。
The shuttle moves backwards and forwards through the warp.
梭子在经线中来回移动。
The shuttle flies back and forth on the loom.
织布机上梭子来回飞动。
In most cases it is possible to allow the shuttle to enter the shed before the opening of the shed in front of the reed is as large as the shuttle size.
在大多数情况下,当钢筘前面的梭口尚小于梭子大小(指横截面)时,便可能使梭子进入梭口。
Thus these looms can be run faster than conventional shuttle looms. Also the acceleration of the projectile can exceed that of a shuttle by a factor of about7.
因此片梭织机可以以高于常规有梭织机的速度运转,而且片梭的加速度要超过普通梭子的七倍。
This is to avoid beat - up with the shuttle trapped between the two warp sheets or having a very weak pick the next time around.
这样可以避免梭子依然还在梭口当中时进行打纬,也可避免在下次投梭时投梭力不足。
Normally, the shed starts to change long before the shuttle is completely out of the shed.
通常在离梭子出梭口之前还有很长一段时间时,梭口就开始变化(指梭口闭合)。

Also it requires a finite time to stop the shuttle on the other side of the loom.
而在对侧也需要一定的时间使梭子静止下来(即梭子的制动)。
The speed at which the shuttle is projected through the shed is very important in determining the loom speed.
在确定织机速度时,梭子穿过梭子口时的初始速度是很重要的参数。

Physical laws dictate that, to move through the shed, the shuttle must be accelerated and decelerated. This naturally takes time and energy.
物理定律指出,要想使梭子穿过梭口,梭子必须被加速和减速,这当然需要时间和能量。
If more than one color is needed in the filling, then a number of shuttles and shuttle boxes will have to be used.
如果需要一种以上颜色的纬纱,必须使用多个梭子和多个梭箱。
The shed has to be sufficiently opened and remain open long enough for the shuttle passage.
为了便于梭子的通过,梭口必须充分开启并保持一定的静止时间。
