Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for sensing short grass in a zakura weaving machine.

[0002]

2. Description of the Related Art Conventionally, woven cloth is woven by rushing rushes from a lateral side through a burial path and weaving them with warp threads.

[0003]

However, when the rush is a non-standard short and small grass, that is, it is shorter than the beginning, or the rush may bend or break in the middle when passing through a high road. In such a case, since the non-standard grass is woven as it is, the non-standard grass is pulled out with a pin or the like after the product is finished.

Therefore, the extraction work is complicated,
Furthermore, since the nonstandard grass or the like is pulled out from the finished mat product, the woven pattern of the grass and the warp is broken at that portion, which has a drawback of impairing the appearance.

[0005]

SUMMARY OF THE INVENTION In view of the above, according to the present invention, a left and right rush weed sensing device is provided near both ends of the width of supply of a large number of warp yarns to be weaved with rush. In the loom, if short grass is detected by not sensing the left or right of the left or right grass sensing device, do not stop the operation of the loom within the range of one cycle operation of the loom. In addition, in the range of one cycle operation of the loom, the operation of the loom is once stopped after the ground fastening operation is released by the ground fastening rod, the short and small grasses are removed, and then the rush supply is stopped. The operation of the loom is restarted as it is, and when the operation of one cycle of the loom is completed, the supply of the weeds is restarted.

Further, in a goza weaving machine in which left and right rush detection devices are arranged near both side ends of a supply width of a large number of warp yarns which are supplied in the longitudinal direction for weaving with rush, the left and right rush detection devices are either left or right. When short grass is detected by only one of the looms not being sensed, the weed supply is stopped without stopping the loom operation within the range of one cycle operation of the loom, and the loom Within the range of cycle operation, once the operation of the loom is stopped after the grounding operation is released by the grounding rod, the short and small grasses are removed, and then the operation of the loom is restarted while the supply of the grass is stopped. If the weed supply is restarted at the end of one cycle operation of the loom, and if the left and right weed sensing devices both do not detect the weeds and the non-accident of the weeds is detected, then within the range of one cycle operation of the loom. Loom work The without stopping stopping only the supply of rushes, it was that a cycle operation of the loom is configured to resume the supply of grass upon completion.

Further, another rush detection device is provided in the substantially central portion of the warp yarn feeding width.

In addition, in the method for removing short and small grasses from a weaving machine, the left and right grasses are arranged in the vicinity of both side ends of the width of supply of a large number of warp threads to be weaved with the grass. If short grass is detected by not detecting grass on either the right or left side of the sensing device, the operation of the loom is not stopped within the range of one cycle operation of the loom, and only the supply of grass is stopped. Within the range of one cycle operation of the loom, the operation of the loom is temporarily stopped after the ground fastening operation is released by the ground fastening rod, the short and small grasses are removed, and then the operation of the loom is stopped with the supply of the hay is stopped. When the operation of the loom is completed and the cycle operation of the loom is completed, the supply of grass is restarted.

In addition, in the method for removing short and small grasses of a goza weaving machine, the left and right grasses are removed in the vicinity of both ends of the width of supply of a large number of warp yarns to be longitudinally weaved with the grass. If short grass is detected by not detecting grass on either the right or left side of the sensing device, the operation of the loom is not stopped within the range of one cycle operation of the loom, and only the supply of grass is stopped. Within the range of one cycle operation of the loom, the operation of the loom is temporarily stopped after the ground fastening operation is released by the ground fastening rod, the short and small grasses are removed, and then the operation of the loom is stopped with the supply of the hay is stopped. When the operation of the loom is completed and the cycle of the loom is completed, the supply of hay is restarted. On the other hand, when both the left and right weed sensing devices do not detect the weed and the failure of the weed is detected, the loom is operated once. Demon Without stopping the operation of the loom to stop only supply of grass in the inner one cycle operation of the loom it was to resume the supply of grass upon completion.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, when feeding rush,
When there is a grass having a length out of the standard or a grass which is to be broken during the supply, the left and right of the left and right grass sensing devices sense the grass, but the other sensing device does not sense the grass.

That is, since the length of the grass is short, any of the sensing devices near the both ends of the warp width cannot detect the grass.

In such a non-sensing state, since the operation of the loom is stopped, the non-standard weeds already woven are pulled out from the stopped loom, and the loom is operated again to perform weaving.

At this time, when one of the right and left weed sensing devices does not sense the weed, the operation of the loom is not stopped immediately, but the loom is not stopped within the range of one cycle operation of the loom, and the loom is continuously operated. Stop rush supply only.

When the operation of one cycle of the loom is completed, the operation of the loom is stopped for the first time.

In this way, the loom is continuously operated within the range of one cycle operation, the grass is not supplied during that period, and then the loom is stopped.

In this way, when only one grass within the range of one cycle is lacking, a modified one-cycle weave is made, that is, for example, in a weaving in which one set of four rushes is operated for one cycle, The lack of non-standard grass causes the grass, and when it is pulled out, it becomes a woven state of a set of three rushes, and that part is made of deformed weave and spoils the aesthetics.

Accordingly, when a non-standard grass lack of grass is generated so that the modified weave is not produced, the supply of the grass is stopped, the loom is continuously operated, and the loom is operated after one cycle of operation is completed. To stop.

By doing so, when the weaving is resumed next time, the weeds can be woven in a set of four in one cycle, and the weave does not have a lack of weeds.

When both the right and left weed sensing devices do not sense the weeds, the weaving operation is not stopped within the range of one cycle operation of the loom, only the supply of the weeds is stopped, and the one cycle operation of the loom ends. By restarting the supply of hay at the time point, it is possible to accurately continue the feeding of one cycle of weeds following the weeding just before the non-emergence of weeds in terms of weaving with the warp.

Further, when at least one of the right and left sides of the rush detection device does not detect the rush, by stopping the operation of the loom after releasing the operation of the ground fastening by the ground rod,
Since the short grass is not yet fastened to the ground, the short grass can be easily removed.

Further, when either the left or right of the left and right weeds sensing device does not sense the weeds, only the supply of the weeds is stopped without stopping the operation of the loom within the range of one cycle operation of the loom, and further, the loom Within the range of one cycle operation, after stopping the grounding operation by the grounding rod, the operation of the loom is temporarily stopped, the short and small grasses are removed, and then the operation of the loom is restarted while the supply of the grass is stopped. By restarting the supply of hay at the end of one cycle operation of the loom, the short and small grass is not yet tightened to the ground, and the short and small grass can be easily removed, and the appearance of the mat There is no danger of spoiling the beauty.

Embodiments of the present invention will be specifically described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows an overall front view of the device of the present invention, in which A is a zakka weaving machine, and the weaving machine A weaves rush grass G into a broth and the like. A double-sided feeding device 2 and 3 for manufacturing a tatami mat and arranged on both sides of the loom 1.
The hay grass G is placed, and every time the warp yarn T is stretched forward and backward by the main lever while being provided in front of the loom 1, two rush grasses G are continuously fed from one of the feeding devices 2. The grass G to be fed is sequentially pushed down by the reed 4, and the turf and the like are woven while tightening the grass G with the ground fastening rod 52.

The loom 1 is provided with a loom frame 5, and a weaving stopping device for interrupting power transmission from a drive shaft 6 driven by a prime mover to each operating portion of the loom 1 at a lower portion of the loom frame 5. 7
Is provided.

That is, in the machine frame 5, a prime mover is arranged on the lower rear side, and a drive shaft 6 is interlockingly connected to the prime mover. Power is transmitted from the drive shaft 6 to each operating portion of the loom 1. The weaving machine 1 performs the weaving operation for one cycle each time the drive shaft 6 rotates once. A weaving stopping device 7 is provided between the prime mover and the drive shaft 6, and the weaving stopping device 7 is intermittently operated by a solenoid 8 connected to the weaving stopping device 7, as will be described later. Then, the loom 1 is operated or stopped.

The drive shaft 6 is provided with a pulse generator 110 for generating a pulse signal for each weaving operation for one cycle.

As shown in FIG. 17, the pulse generator 110 mounts a pulse generating cam 108 at a midway portion of the drive shaft 6, while providing a proximity switch 109 on the machine frame 5 for the pulse generating cam.
The pulse generating cam 10 is mounted toward the motor 108 every time the drive shaft 6 makes one revolution, that is, every one cycle of weaving operation.
The tip of 8 comes close to the proximity switch 109,
109 is designed to generate a pulse signal.

The pulse signal is sent to the control device (not shown) of the loom 1, and the counter (not shown) provided in the control device can count the number of pulse signals, that is, the number of weaving operations. I have to.

Thus, each time the drive shaft 6 makes one revolution,
Since the loom 1 is configured to perform the weaving operation for one cycle, even if the rotation speed of the prime mover is changed, the loom 1 performs the weaving operation in conjunction with the prime mover, and accordingly, each part of the loom 1 No need to adjust operation.

As shown in FIG. 2, the weaving stopping device 7 includes a solenoid 8, a lever 9 linked to the output shaft of the solenoid 8, and a lifting rod connected to the tip of the lever 9.
10, a stopper 11 operated by the lifting rod 10,
Actuating rod 12 whose movement is controlled by stopper 11
And a clutch portion 14 for connecting and disconnecting the driven shaft 13 and the drive shaft 6 by the operating rod 12.

The solenoid 8 is actuated by an electric signal from the control device, actuating the clutch portion 14 and operating the loom 1
Stop the weaving operation of.

That is, right and left weeds sensing devices M, M'are provided on the machine frame 5 near both ends of the loom 4 of the loom 1,
The left and right grass sensing devices M, M'are arranged near the edge of the width of the woven cloth, specifically, at the left and right edge positions.
When the grass G is pushed down, the sensor needle m of the sensing devices M and M'is actuated by pushing down the grass G, and the presence of the grass G and the woven grass as expected It senses that it is as wide as it is.

If a short or small rush grass G is fed, one of the left and right rush detection devices M, M'does not detect the rush grass G, so that the short or short grass does not have a prescribed length. It detects that it is rush grass G, and in this case, this non-sensing electric signal is transmitted to the solenoid 8 via the control device, and the clutch portion 14 is operated by the operation of the solenoid 8 to operate the loom 1
Stop the weaving operation of.

As described above, the left and right weed sensing devices M and M'cannot stop the weaving operation through the solenoid 8 only when the left or right sensing device M (M ') does not sense the weed G. It has features.

Here, the loom 1 is operated by the operation of the solenoid 8.
The process of stopping the weaving operation of No. 2 will be specifically described with reference to FIGS. 2, 3, and 4.

As described above, when the solenoid 8 is actuated as shown in FIG. 2, the stopper 11 descends downward through the link mechanism centering on the elevating rod 10 and engages with the operating rod 12 at its tip. The engaging rod is released, and the actuating rod 12 is urged and pulled by the spring 15 to release the clutch 14 from the power transmission via the clutch rod 16, and the drive shaft 6 receives the power from the prime mover. The power transmission path between the power transmission wheel 17 and the power transmission wheel 17 is cut off.

As described above, when the short and small non-standard weeds G are fed into the sloping road, one of the left and right weeds sensing devices M, M'cannot sense and operate. And the non-sensing signal is transmitted via the solenoid 8 to the loom 1
To stop the weaving operation of the loom 1.

Further, the loom 1 is provided with a warning lamp, and one of the left and right grass sensing devices M, M'is sensed.
When the weaving operation of the loom 1 is stopped because M (M ') does not operate, the warning lamp is turned on.

Therefore, the operator can be warned that the short and small grass G must be removed.

As described above, since the left and right sward sensing devices M and M'are arranged near the both side ends of the warp yarn T within the width thereof, either one of the sensing devices M (M ') does not sense the rush G. If
It is possible to know that the nonstandard grass G has been supplied.

Moreover, since the operation of the loom is stopped at that time, the nonstandard grass G is pulled out from the stopped loom 1 and removed, and the weaving operation can be performed again. Compared with the above, it is possible to restart the operation with the eyes of the rush G being closed, and there is no fear that the missing portion of the rush G will be a void, and it is possible to woven zakka with a good appearance.

In the above embodiment, a pair of left and right rush detection devices
M and M'are provided at the left and right edge positions of the width of the woven cloth, respectively.
By providing M ″, it is possible to detect that the short grass G has stopped at approximately the center of the width of the woven cloth.

That is, as shown in FIG. 12, when the weed sensing devices M and M'are provided at the left and right edge positions of the width of the woven cloth, as shown in FIG. When G flies to the end, or as shown in Fig. 12 (b), short and small rush G
Is caught at the start end and does not fly to the end, it detects that one of the left and right rush detection devices M, M'has a rush G and the other rush G
It is possible to detect that the rush grass G was short and small by detecting that there is no.

However, as shown in FIG. 12 (c), rush G
When the hay flies only halfway, the left and right rush detection devices M and M'will detect that there is no rush G, and whether rush G has not fired or whether rush G is short or short. I can't judge.

Therefore, as shown in FIG. 13, when another rush detection device M "is provided in the substantially central portion of the width of the woven cloth, the rush G does not emit as shown in FIG. 13 (a). when,
The central rush sensing device M "detects that there is no rush G, but as shown in FIG. 13 (b), when the rush G is short, the central rush sensing device M" has a rush G. To detect.

As a result, it can be surely determined whether the rush G is a non-fired one or a short one.

(Embodiment 2) In this embodiment, the weaving machine 1 described in the first embodiment is used, and the weaving machine 1 does not sense the weeds G of either the left or right of the left and right weed sensing devices M, M '. In this case, in order to stop the operation of the loom 1 within the range of one cycle of weaving, to stop only the supply of the weeds G, and to stop the operation of the loom 1 when the one cycle operation of the loom 1 is completed. Configured.

Specifically, the weaving operation of the loom 1 is not stopped immediately when one of the sensing devices M (M ') does not sense the weeds G, but rather the three weeds G that follow the weeding machine are used. Only the loom 1 is operated without being sent to the road.

That is, when the short and small rushes G are sent to the rush road, the three rushes G that follow it, in other words, the remaining rush G for one cycle are not sent, and only the loom 1 has three rushes. Weaving operation is performed on G, and then the weaving operation is stopped.

As described above, since the remaining weeds G for one cycle are not fed, after the short and small weeds G are removed, the loom 1
When the operation of is resumed, regarding the weaving with the warp yarn T, it is possible to accurately continue the feeding of the rush G of one cycle immediately following the feeding of the rush G immediately before the short and small turf G, and next to the removed short and small turf G. It does not cause deformation in the weaving.

As described above, the mechanism for stopping the supply of the weeds G without stopping the operation of the loom 1 within the range of one cycle of weaving is as follows.

That is, the bearing 22 is fixed to the upper surface of the inverted L-shaped base metal fitting 21, and one end of the horizontal shaft 23 is pivotally supported by the bearing 22 to attach the left metal 24 and the arm rod to the horizontal shaft 23 on both sides of the bearing 22. Fasten the right metal 25 and the front and rear direction to the arm rod of the right metal 25, and fasten the lower end of the shield plate 26. And protruding, base metal fittings
The electromagnet 29 is fastened to the long plate 28 hung vertically on the 21.A coil spring 31 is stretched between the operating iron piece 30 of the electromagnet 29 and the front operating shaft 27, and the upper end of the coil spring 31 'is attached to the rear operating shaft 27'. The left metal 25 from the rear of the left metal 25 diagonally downward to the first stopper 32
Protruding and sliding it to the rear end of the base metal fitting 21,
A second stopper 32 ′ facing the lower surface of the front operating shaft 27 is attached at the front of 21 and is fixed to the lateral end of the horizontal shaft 23 by metal fastening.
The arm rod 34 is projected from the front side of the 33, and the lower end of the shaft rod 36 with the hook 35 bent at the upper end is loosely connected to the arm rod 34. The hook 35 of the shaft rod 36 is inserted oppositely above the base of the needle base rod 42 that vertically moves the protruding mounting plate 39 below the V-shaped groove 41 of the weed sorter 38, and at the same time, on the inner surface of the weed sorter 38. The upper end of the shield plate 26 is arranged inside the sandwiched feed roller 43 so that it can be moved back and forth, and the lower end of the coil spring 31 'is configured to stop on the front side frame.

Therefore, when the short and small grass G is detected, the electromagnet 29 below the base metal fitting 21 installed in the grass sorters 38, 38 is excited for a certain period of time, and the front part is passed through the coil spring 31 linked to the operating iron piece 30. By lowering the operating shaft 27 and rotating the horizontal shaft 23 forward, the shielding plate 26 tilts forward to close the inside of the sandwiching feed roller 43, and the shaft rod 36 descends to hook 35 at the upper end. While engaging with the needle base rod 42 and stopping the raising operation of the needle base rod 42, the feeding of the three rushes G following the small grass G into the loom 1 is forcibly stopped. After that, the electromagnet 29 is demagnetized by the operation of the timer and the shield plate
26 and the upper end hook 35 of the shaft rod 36 are returned to their original positions and are ready for normal weaving operation. At the same time, the loom 1 stops operating as described above.

When the above-mentioned short and small grass G is sensed, the loom 1 is operated while the feeding of the remaining 3 rushes G is stopped, and the loom 1 is stopped when the idle feeding of the remaining 3 rushes G is completed. The timing of stopping is controlled by the control device.

As described above, when the nonstandard grass G is sensed, the weaving operation is not immediately stopped, but the supply of the grass grass G is stopped and only the weaving operation is continued up to the range of one cycle. When weaving is resumed after removing the nonstandard I grass G, weaving can be carried out while keeping the standard of one cycle of the grass G as it is, and weaving the mat without damaging the appearance. be able to.

(Embodiment 3) In this embodiment, when the weaving machine 1 described in the second embodiment is used and the weaving machine 1 does not sense the weeds G by both the left and right weeds sensing devices M and M '. Within the range of one cycle operation of the loom 1, only the supply of the weeds G is stopped without stopping the operation of the loom 1 and the supply of the weeds G is restarted at the end of the one cycle operation of the loom 1.

Specifically, both the sensing devices M and M ′ rush G
When it is not sensed, it is determined that the weeds G have not been fired, and the weaving operation of the loom 1 is not immediately stopped, but the three weeds G for the following three looms are not sent to the weed road.
After that, the weeds G were fed into the road for normal weaving operation.

That is, when the rush G is not fired, the three rushes G that follow it, in other words, the remaining rush G for one cycle correspond to the rush G for three looms only without being fed. The weaving operation is to be started and then the weaving operation is restarted.

As described above, since the remaining weeds G in one cycle are not fed, when the operation of the loom 1 is resumed after that, regarding the weaving with the warp yarns T, the weeds G immediately before the non-breaking weeds G are continued. The feeding of the rush G of one cycle can be continued accurately, and the weaving of the weed G that has not failed is not deformed.

As described above, the mechanism for stopping the supply of the weeds G without stopping the operation of the loom 1 within the range of one cycle of weaving is as described in the second embodiment.

Further, in the present embodiment, the operation of the loom 1 is stopped when the non-emergence of the rush grass G is detected a predetermined number of times within a predetermined time.

For example, when two or more misfires occur in 10 seconds, as described above, the three following weeds G, in other words, one cycle of the remaining weeds G are not fed and the loom is not fed. The loom 1 is operated without performing the weaving operation corresponding to the three weeds G for only 1 and then restarting the weaving operation.
The operation of is stopped.

After that, the operator inspects and repairs the loom 1 and restarts the operation of the loom 1, so that the failure of the loom 1 can be prevented.

In this case, the above-mentioned warning lamp is not turned on, and when the loom 1 is stopped, is the loom 1 stopped due to the short and small grass G, or
It is possible to inform the operator whether the loom 1 is stopped because the rush I did not fire.

(Embodiment 4) In this embodiment, the weaving machine 1 described in the second embodiment is used, and the weaving machine 1 does not detect the weeds G of either the left or right of the left and right weed sensing devices M and M '. In this case, without stopping the operation of the loom 1 within the range of one cycle operation of the loom 1, only supplying the weeds G is stopped,
Moreover, within the range of one cycle operation of the loom 1, once the loom 1 is released from the ground fastening operation by the ground fastening rod 52,
Operation of the loom 1 is removed, the short and small grass G is removed, the operation of the loom 1 is restarted with the supply of the grass G stopped, and the supply of the weed grass G is restarted when one cycle operation of the loom 1 is completed. Configured to do so.

That is, when short and small rushes G are sent to the rush road, the three rushes G that follow it, in other words, the remaining rushes G for one cycle are not sent, and only the loom 1 has 3
Although the weaving operation corresponding to the main weeds G is performed, the weaving operation corresponding to the three weeds G is not continuously performed, but the loom 1 is released after the ground fastening operation by the ground fastening rod 52 is released. After the operator once removes the short and small grasses G in that state, the remaining weeds G are woven again, and the weeds corresponding to the three grasses G in total are operated. To resume normal weaving operation.

As described above, since the loom 1 is stopped before the ground fastening is carried out again after the ground fastening rod 52 which performs the ground fastening is periodically grounded, the short and small grass G still remains in the ground. It is not tightened and can be removed easily.

As described above, the mechanism for stopping the loom 1 after the ground fastening operation by the ground fastening rod 52 is released is as follows.

That is, as shown in FIG. 10, the middle portions of a pair of substantially L-shaped ground fastening operating rods 51, 51 are pivotally attached to the left and right side portions of the machine frame 5 so as to be rotatable up and down. Tightening rod 51,51
A ground fastening rod 52 extending in the left-right width direction is installed between the front end portions of the rollers, and a roller 53 is rotatably attached to the base end portion of the ground fastening operation rod 51, and the roller 53 contacts the cam 54. Touching.

A plurality of ground fastening pins are provided on the front surface of the ground fastening rod 52.
56 are attached at intervals in the left-right width direction, and the various fastening pins 56 are adapted to tighten the weeds G downward between the adjacent warp threads T.

The cam 54 is attached to the end of the rotary shaft 55, and the rotary shaft 55 is interlockingly connected to the drive shaft 6 through a speed change mechanism so that the four rushes G can be used as a trail. The weaving operation for one cycle of feeding makes one rotation.

A micro switch 57 is arranged immediately below the midway bent portion of the ground fastening operating rod 51, and the micro switch 57 is connected to a control device.

When the roller 53 is in contact with the recess 54a of the cam 54, the ground fastening rod 52 moves in the direction away from the warp yarn T, and the ground fastening operation by the ground fastening rod 52 is released. Become. In this case, the micro switch 57 is in the OFF state.

On the other hand, when the roller 53 is in contact with the circumferential portion 54b of the cam 54, the ground fastening rod 52 moves toward the warp yarn T and the ground fastening rod 52 performs the ground fastening. .
In this case, the ground fastening rod 52 is in contact with the micro switch 57, and the micro switch 57 is in the ON state.

The control device turns on the microswitch 57.
The loom 1 is stopped only when the off state is detected and the micro switch 57 is in the off state.

Although the micro switch 57 is attached to the machine frame 5 via the bracket 58, the contact position between the micro switch 57 and the ground fastening operating rod 51 is changed by displacing the attachment position in the vertical direction. It is adjustable so that the detection timing of the control device can be adjusted.

Further, instead of the micro switch 57, a pulse generating cam (not shown) is attached to the rotary shaft 55, and a proximity switch (not shown) is provided toward the pulse generating cam to provide the above-mentioned pulse generator. A pulse generator having the same configuration as 110 can be configured.

The operation of the loom 1 will be described in detail. In the loom 1 for weaving a broth or the like by alternately feeding two rushes G from the left and right feeding devices 2 and 3, a total of four rushes G are used. By flying, one cycle of rush grass G is driven to operate for one cycle.
When the first rush G is short (see Fig. 13 (a)), the supply of the three rushes G following it is stopped (see Fig. 13 (b)), and the ground fastening rod 52 is tightened. Release it (see Fig. 13 (c)), temporarily stop the operation of the loom 1 in that state, remove the small grass G (see Fig. 13 (d)), and then perform the ground fastening operation by the ground fastening rod 52. The operation is performed (see FIG. 13 (e)), and the normal operation of the loom 1 is restarted (see FIG. 13 (d)).

The second weed G among the four weeds G
If the length is short (see Fig. 14 (a)), the supply of the two rushes G following it is stopped (see Fig. 14 (b)), and the ground fastening operation of the ground fastening rod 52 is released (Fig. 14). (See (c)), in that state, temporarily stop the operation of the loom 1 and remove the short and small rush grass G (Fig. 14).
(see (c)), after that, the ground fastening operation by the ground fastening rod 52 is performed (see FIG. 14 (d)), and the normal operation of the loom 1 is restarted (see FIG. 14 (e)).

(See FIG. 16 (d)), and then the normal operation of the loom 1 is resumed (see FIG. 16 (d)).

[0082]

According to the present invention, since the left and right weed sensing devices are arranged near both ends of the warp width, if one of the sensing devices does not sense the weed, a non-standard weed is supplied. I can know that.

[0083]

When a non-standard grass is detected, the weaving machine is not stopped immediately, but the supply of the grass is stopped and the loom is continuously operated up to the range of one cycle. Therefore, the non-standard grass is pulled out and removed. When the weaving is resumed after that, weaving can be performed while maintaining the standard of one cycle of rush and one set, and there is an effect that the appearance is not impaired.

When both the right and left weed sensing devices do not sense the weeds, the weed supply is stopped within the range of the one-cycle operation of the loom and only the supply of the weeds is stopped, and the one-cycle operation of the loom ends. Since the supply of turfgrass is restarted at the point of time when the weeds were to be sewn, the weaving with the warp thread can accurately continue the feeding of one cycle of the rush that follows the rush that was immediately before the non-grass. There is no effect on the weave of the garment, and there is an effect that the appearance of the mat is not impaired.

When at least one of the right and left sides of the rush detection device does not detect the rush, the loom operation is stopped after the ground fastening operation is released by the ground fastening rod. It is in an unfastened state and has an effect that it can be easily removed.

Further, when either the right or left of the right and left weeds sensing device does not sense the right or left weeds, the operation of the loom is not stopped within the range of one cycle operation of the loom, and only the supply of the weeds is stopped. Within the range of one cycle operation, after stopping the grounding operation by the grounding rod, the operation of the loom is temporarily stopped, the short and small grasses are removed, and then the operation of the loom is restarted while the supply of the grass is stopped. Since the supply of hay is restarted at the end of one cycle operation of the loom, the short and small grass is not yet fastened to the ground, and the short and small grass can be easily removed, resulting in an appearance of the mat. It has the effect of not impairing the aesthetics of.
