DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting confirmation device.
This cutting confirmation device can be used for confirming the cutting when cutting a cloth body having a long cutting length, for example, when manufacturing a futon side.

[0002]

2. Description of the Related Art Conventionally, when fabric products, such as a futon side, are manufactured, cutting and sewing are performed. In the cutting sew sewing, a cloth body is stretched by a spreading machine, and the width direction thereof is cut manually by a cutter to form a ground. Still another ground is manually cut with a cutter to form a ground. Then, the reverse ground and the reverse ground are sewn with a lockstitch sewing machine to form a front side ground and a back side ground, respectively.

[0003] Incidentally, since the above-mentioned steps are performed manually, confirmation of the cutting is also performed manually by an operator. However, inspection with the naked eye is not easy. In particular, if the cutting distance is long, it is not easy to manually check all the cut portions.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a cutting confirmation device which can automatically detect a defective cutting of a cloth.

[0005]

A cutting confirmation apparatus according to the present invention is provided with a base having an extension surface on which a flexible cloth is extended and a rotatable mounting surface on the extension surface of the substrate. Are arranged on the outer peripheral portion, on which the

Is what you do.

[0006] The rolling element is rotatably mounted on the extending surface of the base, and the rolled cloth is placed on the rolling element. Rollers, rollers, and spheres can be used as the rolling elements. The rotation detecting means detects the presence or absence of rotation of the rolling element.
As the rotation detecting means, a photosensor using light, a rotary encoder, or the like can be employed. The engaging portion of the transfer means is engaged with the cloth body, and the structure can be appropriately selected.

[0007]

According to the present invention, the cloth portion between the engaging portion and the rolling element is cut into two cut portions by cutting means. After the cutting, one of the cut portions is transferred in a direction away from the rolling element by the engaging portion of the transfer means.
At this time, when there is a defective cutting, the cut portions divided into two parts are still connected. Therefore, when one cut portion is transferred by the engaging portion, the other cut portion is also displaced in the same direction. At this time, since the rolling elements rotate, the rotation of the rolling elements is detected by the rotation detecting means. According to claim 1

4, the cloth W1 is placed on the X2.
When it moves along the direction, the roller 74 rotates around the axis 73, so that the light from the light emitting portion 75a of the photo sensor 75 is repeatedly shielded and transmitted, and the movement of the cloth W1 is detected, and the detection signal is transmitted. Is input to the control device 9.

In FIG. 1, reference numeral 9 denotes a control device.
Each operation of the spreading machine 12, the separating device 2, the cutting device 3, the transfer device 4, the sewing device 8, and the holding mechanism 6 is controlled. (Operation) First, the spreading process will be described with reference to FIGS. First, in FIG. 15, the reversing machine 12 controlled by the control device 9 advances on the reversing surface 11 in the direction of the arrow Y1 to near the position Y10. Then, the raw roll 14 of the reversing machine 12 is rotated by a motor (not shown) to unravel, and the leading end of the cloth body of the raw roll 14 is placed at the position Y10. In this state, the spreading machine 12 retreats in the direction of the arrow Y2 while unrolling the web roll 14, and when the reversing machine 12 retreats to a predetermined position, the cutter 16 of the spreading machine 12 travels along the shaft 15, and the cloth W1 is moved. It is cut at a predetermined length L1, and the cut surface W10
Is formed. As a result, as shown in FIG. 15, the first cloth body W <b> 1 (the opposite ground) is extended on the extension surface 11. At this time, the ear line W12 of the first cloth body W1 (the opposite side of the patch) coincides with the cutting line S of the passage 17. In this case, the separation plate 20 is waiting at the standby position P3.

Next, the case where the second cloth is extended will be described. In this case, the operation is performed in a state where the separation plate 20 is arranged above the first cloth W1. Broken raw roll 1
The tip of the cloth body No. 4 is placed at the position Y11. In this state, while the web roll 14 is being lifted, the reversing machine 12 moves in the direction of the arrow Y1.
The cutter 16 of the reversing machine 12 travels along the guide shaft 15, and the second cloth W2 (raw cloth) is similarly cut to the predetermined length L1. As a result, a cut surface W20 of the second cloth W2 is formed. As a result, as shown in FIG. 16, the second cloth W <b> 2 (raw cloth) is extended on the separation plate 20. At this time, the ear line W22 of the second cloth W2 (raw cloth) coincides with the cutting line S of the passage 17, similarly to the ear W12 of the first cloth W1.

Next, FIGS. 19A to 19I are schematic diagrams.
The operation of this embodiment will be described with reference to FIG. First, as shown in FIG. 19A, one sheet of the cloth body W <b> 1 having the width L is extended to the extension surface 11. Then, the separation plate 20
Moves from the standby position P3 in the direction of the arrow X1, and reaches the extension position P1. Thus, as shown in FIG. 19B, the separation plate 20 is positioned above the first cloth W1. Next, FIG.
As shown in FIG. 9 (C), the second cloth W2 is extended above the separation plate 20, the clamp portion 50 advances in the direction of the arrow X1, and the clamp portion 50 becomes the position U1. As a result, the clamp unit 50 has the ear wires W12, W2 of the two cloth bodies W1, W2.
It reaches around 2. Thereafter, the clamp portion 50 descends, and the needle of the clamp portion 50 is inserted into and engaged with the two cloths W1 and W2.

In this state, as shown in FIG. 19 (D), the clamp portion 50 retreats in the direction of arrow X2 along with the two cloth bodies W1 and W2 by the strip width dimension A. At this time, when the gap width A is large and the moving distance is short due to the stroke of the cylinder device 42, the driving motor 5
1 is operated, and the pinion 53 and the rack 45
The movement amount of 0 is compensated.

In this case, as shown in FIG. 19D, the ear wires W12 and W22 of the cloth bodies W1 and W2 extend beyond the passage 17. When the width dimension of the first cloth W1 is L and the strip width is 1/3 of the width L, the movement amount of the cloths W1 and W2, that is, the strip width dimension A is ｛( 1/3) × L}. Further, as shown in FIG. 19 (D), before cutting, the separation plate 20 also moves in the direction of arrow X2 to reach the cutting position P2,
In this state, the passage 17 and the blade 34 of the cutter device 35 are located below the separation plate 20 that has reached the cutting position P2. In this state, the blade 34 of the cutter device 35
Follow along. Thereby, the two cloth bodies W1, W2
Of the first cloth body W1 (the opposite side of the strip) is cut by the strip width A, that is, {(｛) × L}. At this time, the second cloth W2 is blocked by the separation plate 20, and is not cut. During the cutting, the needle of the clamp unit 50 is kept on the cloth W
1, inserted into W2.

Thereafter, as shown in FIG. 19E, the clamp portion 50 further retreats in the direction of arrow X2. As a result, the clamp portion 50 reaches the sewing processing surface 18 of the base 1, and the position U3
Becomes Therefore, the cloth W1 engaged with the clamp portion 50,
Ear lines W12 and W22 of W2 also reach the sewing processing surface 18. Thereafter, the clamp unit 50 moves up and removes the cloth bodies W1 and W2.

In this state, the sewing machine 58 runs along the sewing machine traveling path. At this time, since the sewing needle of the sewing machine 58 is operating, the ear wires W12 and W22 as sewing portions of the two cloth bodies W1 and W2 are sewn, that is, stitched together and joined. This forms a wide area futon side. By the way, as shown in FIG.
The remaining land W15 is still placed on the extension surface 11. The width of the remaining land W15 is ｛(2/3) ×
L｝. Then, the separation plate 20 returns to the extension position P1 again, and is disposed on the remaining place W15. Thereafter, as shown in FIG. 19F, the third cloth W3 (having the same width L) is again extended above the separation plate 20 in the same procedure as described above. At this time, the ear wire W32 of the third cloth W3,
The cutting line W15a of the remaining place W15 matches.

In the state shown in FIG. 19 (F), as described above, the clamp portion 50 advances in the direction of arrow Y1 to reach the vicinity of the ear line W32 of the third cloth W3, and the third cloth W3 and The remaining portion W15 is engaged with the clamp portion 50. And
As shown in FIG. 19G, the clamp unit 50 moves across the passage 17 together with the cloth W3 and the remaining ground W15 in the direction of the arrow X2. In this state, the ear wire W32 of the third cloth body is transported by the width A of the strip width, that is, {(）) × L}.

Then, in the state shown in FIG. 19 (G), the remaining portion W15 is cut by the blade 34 of the cutter device 35. Thereafter, as shown in FIG. 19H, the cloth body W3 reaches the sewing processing surface 18. At this time, the remaining land W16 remains on the spreading surface 11. The width dimension of the remaining material W16 is the width A of the strip, that is, {(１ ／) × L}. Further, FIG.
As shown in (I), the separation plate 20 returns to the extension position P1,
The fourth cloth W4 is again extended above the separation plate 20 in the same procedure as described above in a state where the cloth W4 is disposed above the remaining place W16. At this time, the ear line W42 of the fourth cloth body W4 matches the cutting line W16a of the remaining ground W16. And
Transfer and sewing are performed in the same procedure as described above. As a result, one cycle is completed, the first cloth W1 is extended again on the extension surface 11 as shown in FIG. 19A, and the transfer and sewing are repeated in the same procedure as described above. .

In this embodiment, the cutter device 3
Immediately before cutting is performed by the fifth blade 34, the pressing arm 63 descends as shown in FIG. 9, so that the cloth W1 on the extension surface 11 is pressed against the extension surface 11 by the pressing surface 63 a of the holding arm 63. Therefore, the displacement of the cloth W1 at the time of cutting,
Wrinkles are suppressed, the cutting line of the cloth body is maintained in a straight line,
This is advantageous for improving cutting accuracy.

In the above example, the strip width A of the cloth W1 is set to {(1/3) × L}. However, the present invention is not limited to this, and the strip width is set to {(1/2). ) × L}. In this case, the amount of movement of the clamp part 50 is set to be equal to the width of the strip, that is, {(1/2) × L}. Further, 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 when the width of the cloth is not sufficient, the cloth W1 is cut and sewn and sewn by the sewing device 8, whereby "cut and sewn" can be automatically performed. Therefore, as compared with the conventional case where such a process is performed manually, it is advantageous in terms of quality and productivity, and also advantageous in terms of cost. Therefore, the cutting is suitable for manufacturing a futon having a large area formed by sewn sewing.

Further, in the extended state, the upper surface of the first cloth W1 (for example, the remaining fabric W15) and the second cloth W
2 easily contacts the lower surface. In this case, when the cloth W2 is transferred in the arrow X2 direction, the force is applied to the first cloth W2.
1 (for example, remaining land W15). Therefore, 1
"Wrinkles" on the first cloth body W1 (for example, remaining land W15),
“Shift displacement” and the like occur. In some cases, the opposite side 1
1 also remains on the sewing processing surface 1
8 may be transferred.

In this respect, in this embodiment, the separation plate 20 is interposed between the upper surface of the first cloth W1 and the lower surface of the second cloth W2, so that the degree of contact between them is reduced. It is possible,
Separation of both is easy. Moreover, in this embodiment, an appropriate amount of air is blown out from the air outlet 25 of the separation plate 20 at an appropriate time, for example, at a time before the transfer after the cutting is completed.
The degree of contact between the upper surface of the first cloth body W1 (for example, the remaining fabric W15) and the lower surface of the cloth body W2 is reduced, and the sorting is more reliable. Therefore, it is more advantageous to avoid the above-mentioned problems.

By the way, there are many types of web width of the web roll 14 held by the web spreading machine 12. In this regard, in this embodiment, when the sheet is stretched by the spreading machine 12, the edge lines W12, W22, and W32 of the stretched cloth and the cutting line S of the cutting device 3 are formed.
Is a configuration that matches. Therefore, if the cloth is extended so that the ear line coincides with the cutting line S of the cutting device 3, the amount of movement of the clamp portion 50 in the direction of the arrow X2, the amount of cut of the cloth (cut width dimension), and Will match. That is, even if the value of the strip width dimension A of the cloth body changes, it can be adjusted by the movement amount of the clamp unit 50. Therefore, according to the apparatus of the present embodiment, it is possible to cope with a variety of strip width dimensions, and furthermore, it is possible to easily cope with fluctuations in the raw width of the raw roll 14 and fluctuations in the width on the futon side.

In addition, when the strip width A of the cloth W1 is large, the clamp portion 50 at the position U2 in FIG. 13 needs to be largely retracted in the X2 direction. In this case, since the stroke exceeds the forward stroke of the cylinder device 42 (about 400 mm in the embodiment), the movement distance of the clamp portion 50 is insufficient with the cylinder device 42 alone, and the strip width dimension A
May not be achieved. In this regard, in this embodiment, in such a case, the drive motor 51 operates to rotate the pinion 53 in the X2 direction along the rack 45, thereby making up for the insufficient movement amount of the clamp unit 50. . In this sense, in this embodiment, it is easy to cope with a change in the size of the cut edge, and the advantage is obtained that the width of the futon can be easily diversified.

In the state shown in FIG. 19 (D), when the cloth W1 below the separation plate 20 (the stripped ground) is not completely cut by the cutter device 35, the cloth W1 and the remaining ground W15 are not cut. Are still connected together. In this case, the clamp portion 50 is moved along arrow X2 with the cloth bodies W1 and W2.
When retreating in the direction, the remaining land W15 that is not completely cut also moves.
Rotates. As a result, a cutting defect is detected by the light shielding and light transmission of the photo sensor 75. Thus, the photo sensor 7
If a cutting failure is detected by the control unit 5, the control unit 9 stops the apparatus, so that the occurrence of defective products can be prevented beforehand.

Also, 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 body W1. Therefore, the transfer of the cloth W1 and W2 is detected by the light shielding and light transmission of the photo sensor 75, and the transfer of the cloth W1 and W2 is detected. In other words, the transfer of the cloths W1 and W2 is based on the premise that the cloths W1 and W2 are engaged by the clamp unit 50, so that the engagement by the clamp unit 50 can be detected.

In addition, in this embodiment, when the first piece of cloth W1 is cut off, as shown in FIG. 9, the holding arm 63 is lowered and the cloth W1 on the extension surface 11 is pressed. The arm 63 is pressed against the extension surface 11 by the pressing surface 63 a.
Therefore, displacement and wrinkles of the cloth W1 at the time of cutting can be suppressed, which is advantageous in improving cutting accuracy. In this embodiment, when the cutting step is performed, the first cylinder device 2
The locking pin 235 of the locking portion 21d locks into the first locking hole 20a of the separation plate 2 and the second cylinder device 22
The locking pin 235 of the locking portion 22d is locked in the second locking hole 20b of the separation plate 2. For this reason, the holding stability of both ends of the separation plate 20 is increased, and further, the degree of fixation of the separation plate 20 is secured, and the play of the separation plate 20 at the time of cutting is suppressed, which is advantageous for further improving the cutting accuracy. It is.

[0041]

According to the cutting confirming device of the present invention, after cutting, one cut portion is transferred in a direction away from the rolling element by the engaging portion of the transfer means. At this time, when there is a defective cutting, the cut portions divided into two parts are still connected. Therefore, when one cut portion is transferred by the engaging portion, the other cut portion is also displaced in the same direction, and the rolling element rotates, so that the rotation of the rolling element is detected by the rotation detecting means. Therefore, a cutting defect is automatically detected.
