Description

[Detailed Description of the Invention] Conventionally, when weaving tatami mats, rushes are placed on the rush holder of a power loom and woven.In this case, the rushes to be used are held in advance by hand, one handful at a time, and the base is covered with concrete, etc. The grass is pounded onto the floor of the loom, and then cut at a certain length from the base using push-cuts, etc., and then placed on the rush holder of the loom.

This pounding process causes the roots of slow-growing rushes with soft roots to bend and stick out, while for rushes with hard roots, the work is simply a matter of aligning the roots.

Normally, the hardest part of a rush is 3 to 5 centimeters from the tip of its root, but if the root is soft, it cannot be woven, so it is necessary to make the hardness more or less uniform.

However, the above-mentioned conventional work has been carried out exclusively by hand, that is, by grasping the rushes one by one for a long time, and is extremely inefficient.

In recent years, a rush source alignment device has been proposed to solve this problem, but this device places the rushes in a rush box while standing vertically. It is difficult to put in and take out the rushes, and since the rushes are moved up and down while standing vertically, and after being leveled, the rushes are laid down before being cut, which causes them to warp, making the process troublesome and difficult to handle.

The present invention aims to eliminate such conventional drawbacks, and an example of the implementation of the present invention apparatus will be described below with reference to the drawings.

When the pulley 40 rotates through the electromagnetic clutch 38 and the disc 35 rotates through the electromagnetic clutch 38, the slider 31 connected to the link 33 slides up and down, and at this time the cutting blade 3
2 similarly slides up and down to perform the rush cutting operation described later.

Reference numeral 41 denotes a rotation shaft that rotates the disk 35 by the rotation of the pulley 39, and bearings 43 and 43' are provided on the top plate 42 formed by bridging the upper edges of the side wall plates 26 and 26'. It is supported by

Reference numeral 44 denotes a sprocket attached to the shaft end of the rotary shaft 41 opposite to the disk 35, and when the rotary shaft 41 rotates through the chino 45, the side wall plates 26 and 26' move toward the guide rails 24, 24. ' to make it slide along the '.

That is, a rotating shaft 46 is attached to the lower inner surface of the side wall plates 26 and 26', spanning between the two, and 41 (bearing attached to the inner side of the side wall plate 26, not shown) 47' is a bearing for this purpose. 48 is a sprocket fixed to the rotating shaft 46.

On the other hand, a guide plate 50 having an endless chain band 49 attached to the entire circumference of the cutlery box 21 is attached via a support 51 from the inner wall of the cutler case 21.
A sprocket 52 meshes with the top of the rotating shaft 46, and is rotated together with the rotation of the rotating shaft 46.

Reference numeral 53 denotes a rotating shaft of the sprocket 52, and this shaft and the rotating shaft 46 are connected by a bridge plate 54, and 55a and 55b are on the side of the bridge plate that rotatably supports each rotating shaft. It is a fixed boss.

Thus, 56 is a sprocket integrally fixed to the rotating shaft 46 side, 57 is a sprocket opposite to the sprocket 56 and integrally fixed to the rotating shaft 53 side, and there is a space between both sprockets. The chain 58 is hooked so that the rotation of the rotating shaft 46 is transmitted.

On the other hand, a guide rail 59 is attached to the opposite wall side of the knife case 21 to which the guide plate 50 is attached in a parallel state facing the guide plate 50. It is made to be held between guide rollers 62a and 62b which are pivotally supported by a roller receiver 61 rotatably attached to the shaft end via a bearing 60.

(See Figure 5) This causes the sprocket 57 to
When the rotation from 6 is made to rotate through the chino 58, it rotates endlessly while meshing with the endless chain band 49 of the guide plate 50 (see Fig. 4), and the cutting blade 32 is attached. The side wall plates 26, 26' are made to reciprocate along the guide rails 24, 24'.

In the drawing, reference numerals 63a and 63b are limit switches, and when the cutting blade 32 moves back and forth while moving up and down, and the roller 28b comes into contact with the limit switch 63b at the end of the forward stroke, the electromagnetic clutch 38 is activated. is turned off, the contact with the rotating shaft 41 is cut off, the vertical movement of the cutting blade 32 is stopped, and the roller 28 is turned off.
When a contacts the limit switch 63a, the motor 34 stops driving with the electromagnetic clutch 38 engaged, and the machine waits for the next operation.

The device of the present invention is constructed as described above, and initially the cutlery box 21
is moved to the position H indicated by the dashed-dotted line in FIG.

Next, when the motor 6 is driven by operating a switch on an operation panel (not shown), the w throat 8 reciprocates due to the rotation of the disc 7, swinging the link 11 in the directions of arrows A and B, and along with this, the rod The rush box 2 and the beating board 17 are similarly swung in the A and B directions via 13 and 16.

In this S, the direction of the swinging force of the rush box 2 and the beating board 17 is the opposite movement, that is, the swinging direction of the rush box 2 is the direction of the swinging of the rush board 17.
In addition, as the rush box 2 swings in the direction toward the opening, the beating plate 17 swings in the direction A, and therefore strikes the base molecules of the rushes 65.

As a result, the roots of the rushes 65 are leveled, and the soft rushes at the roots come out slightly drooping.

In this manner, when the stamp is stamped for a certain period of time, the drive of the motor 6 is stopped, and the rush 65 is pressed and fixed from above by a tightening means (not shown) provided inside the rush box.

Next, move the knife case 21 from the dashed-dotted line position H in FIG. 1 to the solid line position, and operate the switch on the operation panel to
Let it drive.

Then, the pulley 40 rotates, and the disk 35 rotates at the edge of the rotating shaft 41, and the slider 3 is rotated via the link 33.
1 is moved up and down, and the cutting blade 32 is similarly moved up and down.

On the other hand, the sprocket 44 rotates at the other end of the rotating shaft 41, and this rotation is transmitted to the sprocket 48 via a checker 745.
The rotation is caused by the guide plate 5 via a sprocket 56 and a checker 758 fixed to the rotating shaft.
The sprocket 52 that meshes with the endless chain band 49 of 0 is rotated, and thereby the side wall plates 26 and 26' supporting the vertically moving cutting blade 32 are connected to the guide rail 24.
, 24' and run in the direction of arrow C.

The present invention is designed to cut a desired length from the soft rush part that is compressed and fixed in the rush box 2 and hanging down on the front part of the rush body by the above-mentioned running, and from the rush root part. The cutting action is achieved by the roller 28b coming into contact with the limit switch 63b on the side wall of the case, which turns off the electromagnetic clutch 38, cutting off the contact with the rotating shaft 41 and disabling the vertical movement of the cutting blade 32. However, the sprocket 52 changes direction from the upper endless chain belt to the lower endless chain belt of the guide plate 50, and similarly engages and runs, so that the side wall plates 26, 26 supporting the cutting blade 32
' is again guided by the guide rails 24, 24' and returns in the two directions of the arrows.

(See FIG. 4) When the roller 28a comes into contact with the limit switch 63a, the drive of the motor 34 is stopped with the electromagnetic clutch 38 engaged, and the motor 34 is on standby for the next operation.

As described above, the roots of the rushes can be leveled and the soft unnecessary parts can be cut and removed, and the product thus obtained is taken out of the rush box 2 and placed on the tatami loom. It is carried.

After this, rushes are again put into the rush box 2, and the pretreatment work is performed in the same manner.

In the above embodiment, the knife case 21 is rotated 900 degrees in the front horizontal direction using the pin 23 as a fulcrum during the initial rush leveling work, but it can be rotated upward by a certain angle using a hinge or the like. It may be configured such that it can be raised.

In addition, the above-mentioned work of leveling the rushes and cutting the root edges can be configured in a fully automatic manner, such as a relay working to perform the cutting work at the same time as the leveling work is completed, and the present invention includes these. Within the scope of implementation.

In the present invention, the rush box is placed at an inclination of 5° to 35° in order to effectively carry out the alignment work, and if it is less than 5°, the rushes in the rush box are not much different from the horizontal state. Therefore, the alignment effect will be weakened, and if the angle is more than 35 degrees, the rushes will become uneven and the opposite effect will appear.

According to the inventor's experiments, it depends on the type of rush, but it is 100 to 2
A range of 5° is preferred.

According to the device of the present invention, it is possible to perform efficient alignment work and cutting work at the same time, thereby contributing to improved productivity and labor saving.
