It matches the above.

In the state shown in FIG. 19F, similarly to the above, the clamp portion 50 advances in the direction of the arrow Y1 to reach the vicinity of the earline W32 of the third cloth W3, and the third cloth W3. The remaining portion W15 is engaged with the clamp portion 50. And
As shown in FIG. 19 (G), the clamp part 50 moves in the direction of the arrow X2 along with the cloth body W3 and the remaining ground W15 across the passage 17. In this state, the selvage line W32 of the third cloth body is transferred by the width A of the strip, that is, {(1/3) × L}.

Then, in the state shown in FIG. 19G, the remaining land W15 is cut by the blade 34 of the cutter device 35. Thereafter, as shown in FIG. 19 (H), the cloth body W3 reaches the sewing processing surface 18. At this time, the remaining land W16 remains on the extension surface 11. The width dimension of the remaining land W16 is the width width dimension A, that is, {(1/3) × L}. Furthermore, FIG.
As shown in (I), the separating plate 20 is returned to the extending position P1,
The fourth cloth W4 is again extended above the separating plate 20 in the same manner as described above while being arranged above the remaining land W16.

At this time, the earline W42 of the fourth cloth W4
And the cut surface W16a of the remaining ground W16 both coincide with the virtual cutting line S. Then, transfer and sewing are performed in the same procedure as described above. By this, one cycle is completed, the first cloth W1 is again spread on the spreading surface 11 as shown in FIG. 19 (A), and the transfer and sewing are repeated in the same procedure as described above. ..

By the way, in the above-mentioned example, the strip width dimension A of the cloth W1 is set to a value of {(1/3) × L}, but the present invention is not limited to this, and the strip width dimension is {(1/2). ) × L} may be set. In this case, the amount of movement of the clamp portion 50 is set to the width of the strip, that is, {(1/2) × L}. Furthermore, the strip width dimension is {(1/4) × L},
The value can be set to {(1/5) × L} or another value.

(Effect) As described above, in this embodiment,
Even if the width of the cloth body is insufficient, the cloth body W1 is cut and sewn by the sewing device 8, whereby the “cutting and sewing” can be automatically performed. Therefore, it is advantageous in terms of improvement in quality and productivity, and also in terms of cost, as compared with the conventional method in which such a step is manually performed. Therefore, it is suitable for manufacturing a large-sized blanket side formed by cutting and sewing.

Furthermore, in the stretched state, the upper surface of the first cloth W1 (for example, the remaining cloth W15) and the second cloth W
The lower surface of 2 easily contacts. In this case, when the cloth W2 is transferred in the direction of the arrow X2, the force thereof is
1 (for example, remaining land W15) is likely to occur. Therefore, 1
Wrinkles on the first cloth W1 (for example, remaining land W15),
"Slip displacement" etc. occurs. In some cases, spreading surface 1
The remaining area W15 which should remain as it is is also the sewing surface 1
There is a possibility that a problem of being transferred to No. 8 may occur.

In this regard, in this embodiment, since the separating plate 20 is interposed between the upper surface of the first cloth W1 and the lower surface of the second cloth W2, the degree of contact between the two is reduced. It is possible,
It is easy to separate the two. Moreover, in this embodiment, since an appropriate amount of air is blown out from the air outlet port 25 of the separation plate 20 at an appropriate time, for example, at the time after the cutting and before the transfer,
The degree of contact between the upper surface of the first cloth W1 (for example, the remaining ground W15) and the lower surface of the cloth W2 is reduced, and the division is further ensured. Therefore, it is more advantageous to avoid the above-mentioned problems.

By the way, there are many kinds of raw fabric width dimensions of the raw fabric rolls 14 held by the fabric spreading machine 12, and it is preferable to be able to cope with many types of raw fabric rolls 14. In this regard, in this embodiment, when the cloth is spread by the spreading machine 12, the ears W12, W22, W32 of the cloth that has been spread and the virtual cutting line S match. Therefore, if the cloth is spread by the spreading machine so that the selvages match the virtual cutting line S of the spreading surface 11, the stripping amount (split width dimension) of the cloth will be in the direction of the arrow X2 of the clamp portion 50. It becomes equal to the movement amount to.

Therefore, in this embodiment, from the original roll 14 having a large width L to the original roll 14 having a small width L
Even if the width is changed from the original roll 14 having a small width L to the original roll 1 having a large width L.
Even if it is changed to 4, there is an advantage that the value of the strip width dimension A can always be kept constant. Furthermore, even if the value of the strip width A of the cloth changes, it can be dealt with by adjusting the amount of movement of the clamp portion 50. That is, when the value of the strip width dimension A is increased, the amount by which the clamp portion 50 moves from the virtual cutting line S in the X2 direction is increased. Further, when the value of the strip width dimension A is reduced, the amount of movement of the clamp portion 50 from the virtual cutting line S in the X2 direction is reduced. Therefore, according to the apparatus of this embodiment, there is an advantage that the width of the strip can be arbitrarily selected. Therefore, it is possible to deal with a wide variety of strip width dimensions, and it is possible to easily deal with a variation in the width dimension on the futon side.

In addition, in this embodiment, the following advantages can be obtained, that is, when the strip width A of the cloth W1 is large, the clamp portion 50 at the position U2 in FIG. 13 is large in the X2 direction. You need to step back. In this case, the forward stroke of the cylinder device 42 (about 400 m in the embodiment)
m), the moving distance of the clamp portion 50 may be insufficient with the cylinder device 42 alone, and the strip width dimension A may not be achieved. In this respect, in this embodiment, in this case, the drive motor 51 operates to cause the pinion 53 to roll along the rack 45 in the X2 direction, thereby compensating for the insufficient movement amount of the clamp portion 50. .. Also in this sense, in the present embodiment, it is easy to deal with the change in the size of the width of the pad, and there is an advantage that it is possible to easily cope with the diversification of the width size on the futon side.

Further, in the state shown in FIG. 19 (D), when the cloth W1 (barbed cloth) below the separating plate 20 is not completely cut by the cutter device 35, the cloth W1 and the remaining cloth W15. And are still connected. In this case, the clamp portion 50 moves together with the cloth bodies W1 and W2 along the arrow X2.
When retreating in the direction, the remaining land W15, which is not completely cut, also moves.
Rotates. As a result, defective cutting is detected by the light shielding and light transmitting of the photo sensor 75. Photo sensor 7
When the cutting defect is detected by 5, the control device 9 stops this device, so that the generation of defective products can be prevented.

Further, from the state shown in FIG.
In the state shown in FIG. 9 (D), the cloth body W1,
When W2 is transferred, the roller 74 is rotated by the lower cloth W1. Therefore, the transfer of the cloth bodies W1 and W2 is detected by the light shielding and light transmission of the photo sensor 75. That is, in order for the cloth bodies W1 and W2 to be transferred, it is premised that the clamp bodies 50 engage the cloth bodies W1 and W2. Therefore, the cloth body engagement by the clamp portion 50 can also be detected. ..

In addition, in the present embodiment, when the first cloth W1 is cut off, the pressing arm 63 descends and the cloth W1 on the spreading surface 11 is pressed as shown in FIG. The extension surface 11 is pressed by the pressing surface 63 a of the arm 63.
Further, as shown in FIG. 10, the length of one of the pressing arms 63 is longer than "dimension J", and since the two pressing arms 63 are continuously arranged through the pin 62i, the cloth body The pressing distance is substantially (J + J), which is considerably long. Therefore, the shift and the wrinkle of the cloth W1 during the cutting are surely suppressed, and the cut surface is maintained straight.
Therefore, there is an advantage that cutting accuracy and cutting quality can be improved.

Further, in this embodiment, when the cutting process is performed, the locking pin 235 of the locking portion 21d of the first cylinder device 21 is locked in the first locking hole 20a of the separation plate 2 and the second The locking pin 235 of the locking portion 22d of the cylinder device 22 locks in the second locking hole 20b of the separation plate 2. Therefore, the holding stability of both ends of the separation plate 20 is increased, and the degree of fixation of the separation plate 20 is secured, and the rattling and deviation of the separation plate 20 during cutting are suppressed, which is advantageous for further improvement of cutting accuracy. Is.

Further, in the present embodiment, thread replacement of the sewing machine 88,
When performing maintenance, as described above, since the sewing machine installation table 87 can be unlocked and swiveled, thread replacement work and maintenance work can be performed easily. When the sewing machine installation table 87 is turned, as described above, the dog 85e of the movable section 85 is switched to the switch section 8 of the limit switch 87e.
Since 7f is separated, the turning signal is input to the control device 9. Therefore, since the drive motor 80 of the sewing device 8 cannot be driven when the sewing machine installation table 87 is rotated,
The sewing machine 88 cannot run. Therefore, thread replacement work,
Safety can be secured during maintenance work.
