Description

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

Conventionally, when weaving flower stems on a lotus loom, two types of rush, uncolored grass and grass to be colored in the desired color, are supported in the rush divider and catcher on both sides of the loom, and the warp threads are moved in the front of the loom. Colored rush 5 and non-colored rush are fed in alternately 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, in the case of a so-called misfire, in which the rush gets caught in the middle of feeding and is not fed into the warp threads, the back grass becomes spots on the surface of the violet and becomes visible. The grass that wants to be guided into the warp is pressed against the ground tightening rod by a rush detection mechanism. A detection mechanism detects the misfires of rushes and measures them using a counter. For example, if three or more rushes misfire during one [phase], the loom is automatically stopped and the cause of the rush is inspected and repaired. This is what we are doing. However, if 1 or 2 rushes occur within 10 seconds, the weaving operation is continued, and after weaving is finished, the unexploded area is inspected, and the three rushes in front and behind the unexploded area are manually pulled out. This is corrected by pulling the upper and lower rushes into the gap that has been pulled out. Therefore, there was a drawback that a lot of time and effort was required for the correction work, and the commercial value of the violet also decreased due to the correction. In order to eliminate the above-mentioned drawbacks, the present invention is a device that prevents rushes from falling through by automatically stopping the following three rushes when a grass detection mechanism is detected to be installed in the grass rod. The present invention is characterized in that it is possible to prevent the occurrence of weed shedding in the woven flower lotus, and to obtain flower violets with high commercial value at all times.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

Rush trailing devices 3, 3'' that interlock with color arrangement devices 2, 52'' are attached to positions near the front on both sides of the machine frame 1.
Uncolored rush and colored rush are supported by the receiving trough and rush divider 3, 3'' which protrude outward from the machine frame 1, and are fitted into the gaps between the many warp yarns 4 which are stretched from the top to the bottom on the front of the machine frame 1. A road frame 66 on which a guide rod 5 is to be protruded from the back surface 5 is supported in front of the warp threads 4 so that it can be guided diagonally downward, and a reinforcing rod 7 is supported behind the warp threads 4 so that it can be guided up and down. Grass feed rollers 8 and 8 provided inside the weeding devices 3 and 3'' are used to sandwich the four rushes separated one by one by the weeding devices 3 and 3. , 9'' Is it possible to move the grass through the warp threads 4 and move it up and down while flying it into the thread thread 5? Violet loom 1 for bag weaving 10
1, a receiving plate 12 for receiving the rattuparos 9, 9'' at both ends of the guide frame 6 which is guided diagonally downward back and forth is provided inside the clamping feed rollers 8, 8'', and a bearing is installed above the receiving plate 12. 1
3 is provided to pivotally support the shaft 14, and a shielding plate 15 that can close the inner end of the ratuparo 9, 9'' and the receiving plate 12 is suspended from the right end of the shaft 14, and a shielding plate 15 is provided hanging from the right end of the shaft 14. An arm rod 16 is provided protruding from the shaft 14, and an arm rod 16'' is provided protruding forward from the left end of the shaft 14, a spring 17 is tensioned between the arm rod 16 and the machine frame 1, and left and right magnets provided on the machine frame 1 are attached. Shielding device 19, 19'' for ratuparo 9, 9'' of the road frame where you want to tension spring 17'' between the operating iron piece 18, 18'' and the arm rod 16'', 16''
7 rush sensing rod 2 is installed from an arbitrary reed shaft 7'' that is rotatably supported on the reed rod 7 at the central position of the reed rod 7.
0 is bent toward the lateral lower surface of the reed shaft 7'', and an actuating plate 21 is vertically fixed to the rear end of the reed shaft 7'' which is provided to protrude rearward of the reed rod 7. The other end of the spring 22, which has one end hooked to the hook, is hooked and attached to the upper end of the actuating plate 21, and a shaft piece 23 is provided to protrude rearward from the lower end of the actuating plate 21. A cam box 24 is fixed inside the loom, and a grass sensing device 27 is provided inside the cam box 24, which includes a cam 25 that can engage with the shaft piece 23 and a microswitch 26, and a control device installed inside the loom. The circuit is designed to connect the rush sensing device 27 and the Latsuparo shielding devices 19, 19''.

At the same time, the effects of the present invention will be explained with reference to embodiment figures.

In the violet loom 11, uncolored rush and colored rush are fed into the ditch rod 5 on the back side of the ditch frame 6 from the trailing devices 3 and 3'' provided on both sides of the machine frame 1, and the rush frame 6 is At the same time as the grass is opened diagonally downward in the front, the weeding rod 7 descends and presses the grass to be threaded through the warp threads 4 to the lower ground tightening rod to weave the flower violet 10. After four uncolored rushes and colored rushes are sent out alternately from 3, rushes are sent out in the same way from the rush divider 3'' on the left side. When one rush is passed through the warp thread 4 and the reeding rod 7 is lowered, the rush sensing rod 20 of the weed detection device 27 to be installed on the reeding rod 7 comes into contact with the rush and is pressed upward. axis 7
'' rotates clockwise in front view, the actuating plate 21 also rotates clockwise and the shaft piece 23 separates from the cam 25, and even if the reed lever 7 descends, the microphone port switch 26 does not operate. If the rush detection rod 20 is not pressed by the rush, the shaft piece 23 of the actuating plate 21
As the reed rod 7 descends, it engages with the cam 25, rotates the cam 25, and the contact point of the microswitch 26 becomes 0N, detecting the failure of rush grass. The magnets 18, 1'' are energized, and the operating iron pieces pull the arm rods 16'', 16'' upward via the springs 17'', 17'', and the shielding plates 15, 15 at the other end of the shaft 14 move forward. Rotate and receive plate 12, 1 of Ratsuparo
2 and the runner frame 6 return to the upper position and cover the inner ends of the ratuparos 9, 9'' connected to the receiving plates 12, 12. Meanwhile, the violet loom 11 is operated continuously. , continuous to the unexploited rushes, use the trailblazer 3 or the rush racer 3''
Shielding plates 15, 15 for the following three rushes sent in
This is to stop the rush at Ratsuparo 9,9'', and it falls downward every time the stopped rush track frame 6 is opened.The subsequent three rushes are stopped by a timer circuit. By holding and stopping the magnets 18, 1'', and then demagnetizing the magnets 18, 1'', the shielding plates 15, 15 retreat to their original positions, releasing the shielding of the Ratsuparo 9, 9'', and after a misfire. The feeding operation is resumed from the fourth rush. Therefore, in the case of bag weaving in which the four rushes successively fed to the warp yarn 4 have different passing positions, the violet loom 11 is forced to stop feeding the three rushes following the unexploded rush.
In order to run the weaving violet 10 idly, spots due to rush weeding do not occur on the woven violet 10, and even if the feeding of the four rushes is stopped, it may not have a significant effect on the violet 10 that is being woven. It is possible to efficiently weave flower violets, which have high commercial value, and can also be used to weave flower violets into which two rushes are fed in from the left and right as a set, or to prevent rushes from falling through the tatami surface. It has various effects.
