Description

[Detailed description of the invention] Industrial field of application This invention relates to a device for preventing rushes from slipping through in a tatami facing loom.

Conventional technology Conventionally, when weaving a tatami surface using a tatami surface loom, uncolored rush was supported on the rush divider and catcher on both sides of the loom, and the grass trays were placed in front of and behind the warp threads provided at the front of the loom. into the opening for,
Each time the warp threads are stretched forward and backward by the thumb rod, two uncolored rushes are first fed in from the rush divider on the right side, and then two uncolored rushes are fed in from the rush divider on the left side.
The books are fed in and pushed down one by one, and the rushes are tightened with a jigijime rod to weave the tatami mat one by one.

Problems that the invention aims to solve: However, if even one rush fails during feeding, the rush will fall through the tatami surface, exposing the warp threads to the surface and reducing the product value. Therefore, after weaving is completed, the tatami surface is inspected, and in the case of a defective spot, another rush is pulled out and the upper and lower rushes are pulled into the gap to correct the problem. However, the above-mentioned correction work requires a lot of time and effort, and when other rushes are pulled out at the point where the rush has failed, the four rushes above and below are fed in from the same direction, and the base of the grass root and the tip overlap. However, there were drawbacks such as the color being different from other woven parts, reducing the commercial value.

In order to solve such problems, the present invention has a grass sensor installed on the rush rod that detects the failure of the rush feeder and detects the failure of the rush feeder when the rush feeder fails to explode. The invention is characterized by stopping the operation of the tatami mat surface during weaving, and tilting a shielding plate inside the nipping feed roller to stop the three rushes that have failed, thereby preventing the occurrence of rushes falling through due to misfires on the tatami surface during weaving. It is.

Means for Solving the Problems The configuration of the present invention will be explained below with reference to embodiment figures.

A bearing 2 is fixed to the upper surface of the inverted L-shaped base metal fitting 1, and one end of the horizontal shaft 3 is supported by the bearing 2.
The left metal 4 and the right metal with arm rod 5 are fastened to the horizontal shaft 3 on both sides of the frame, and the lower end of the shielding plate 6 facing in the front and back direction is fastened to the arm rod of the right metal 5. A front operating shaft 7 and a rear operating shaft 7' are provided protruding from the surface, and an electromagnet 9 is attached to a long plate 8 hanging from the base metal fitting 1.
A coil spring 11 is stretched between the operating iron piece 10 of the electromagnet 9 and the front operating shaft 7, and the upper end of the coil spring 11' is engaged with the rear operating shaft 7'. A first stopper 12 is provided to protrude more obliquely downward and is brought into contact with the rear end of the base metal fitting 1, and a second stopper 12' is attached to the front part of the base metal fitting 1 facing the lower surface of the front operating shaft 7,
An arm rod 14 is provided protruding in the front direction from the metal 13 fixed to the side end of the horizontal shaft 3, and the lower end of the shaft rod 16, which has a hook 15 curved at the upper end, is loosely tied to the arm rod 14. At the lower position of the trailing device 18 to be installed on the left and right sides, the mounting plate 19 protruding from the base metal fitting 1 is secured to the front side frame 20 of the tatami face loom 17. The hook 15 of the shaft rod 16 is inserted oppositely above the base of the needle post rod 22 which moves up and down, and the upper end of the shielding plate 6 can be moved back and forth inside the clamp feed roller 23 arranged on the inner surface of the rush divider 18. The lower end of the coil spring 11' is fixed to the front side frame.

Functions and Effects The rush prevention device according to the present invention is applied to the tatami surface loom 1.
Install it at the lower position of the trailing device 18 that you want to install on both sides of the trailing device 1, and attach the upper end hook 15 of the shaft rod 16 to the trailing device
8, and the shielding plate 6 is arranged to face the inside of the rush holding and feeding roller 23, and in the normal state, the needle stock moves the rush up and down in the V-shaped groove 21 of the rush divider 18. The needles of the rod 22 are used to pierce and lower the strands one by one, and then the strands are fed horizontally into the clamping feed rollers 23 using a lateral feed plate (not shown), and then into the groove of the tatami surface loom 17 from the left and right burr dividers. The tatami mats are woven as the books are fed in one by one. If the rushes that are being fed fail to explode on the way, the grass detectors installed in the reed rods will detect this, and by operating the switch, the rush dividers 18 on both sides will be activated.
The electromagnet 9 below the base metal fitting 1 installed at 18 is energized for a certain period of time, and the front operating shaft 7 is lowered via the coil spring 11 linked to the operating iron piece 10, and the horizontal shaft 3 is rotated forward. The shielding plate 6 tilts forward and closes the inside of the clamp feed roller 23, and the shaft rod 16 descends and the hook 15 at the upper end engages the needle rest rod 22, stopping the upward movement of the needle rest rod 22. While doing so, the feeding of the three rushes following the weed to be unexploded into the loom is forcibly stopped, and then the electromagnet 9 is demagnetized by the timer operation, and the shielding plate 6 and the upper end hook 15 of the shaft rod 16 are returned to their original positions. The machine returns to normal weaving operation and continues normal weaving operation.

Therefore, if one rush fails on the tatami facing loom, the following three rushes sent from the left and right rush dividers will
By forcibly causing the rushes to fail, it is possible to obtain a tatami mat surface with high commercial value without causing any rush shedding on the surface of the tatami mat, and other remarkable effects as described above can be achieved.
