Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing flower stems from falling through when weaving flower stems using a lid loom.

Conventionally, when weaving flower stems using a lid loom, two types of rush, uncolored rush and colored rush colored in the desired color, are supported on the rush divider and catcher on both sides of the loom, and the front of the loom is supported. Colored and non-colored rushes are fed alternately into the warp threads of the weave to create a bag weave. In bag weaving, the rush divider on the right side of the loom feeds in two pieces of colored rush and two non-colored rushes, and then the rush divider on the left side of the loom feeds colored rush and non-colored rush in the same way. However, while feeding the rushes, the rushes sometimes get caught and cannot be fed into the warp.
In the case of so-called non-explosion, the undergrowth appears as spots on the surface of the flower stem, or the rush occurs as spots on the underside of the flower stem. A weed detection mechanism is installed in the reed rod that presses the grass to be guided against the ground tightening rod, and the detection mechanism detects the misfires of rushes and measures them with a counter.For example, if three or more misfires occur in milliseconds, the loom There are some that automatically stop the engine so that the cause of the misfire can be inspected and repaired. However, 1 per m seconds
In the case of two or two unexploded rushes, continue weaving, check the unexploded area after weaving, manually pull out the three rushes in front and behind the unexploded area, and insert the upper and lower rushes into the gap that was pulled out. Some fix it by attracting rushes. Therefore, there is a drawback that a lot of time and effort is required for the correction work, and the commercial value of the flower stem decreases due to the correction. In order to solve the above-mentioned drawbacks, the present invention provides a rush detection mechanism in the reed rod 6 of a loom, and at the same time detects the failure of the rush without stopping the loom. In addition to shielding the ratuparo guiding the rushes to the path, the cam rod of the color mechanism that operates the rush divider is stopped, and the operation of the rush divider is stopped, stopping the 73* rush that followed the unexploded rush. It is characterized by preventing the occurrence of spots due to shedding of the woven flower stalks.
