The details of the structure are as illustrated in FIG. 17, in which the fabric 1 is slidably fitted onto the formwork 5, and the fabric 1 is held by a pair of rotatable guide rollers 4, 4. The formwork 5 is used to position the fabric 1 during cutting, and the active feed roller 6 is used to detect flaws in the fabric 1. Therefore, although not shown in the drawings, a counter is provided to count the length of the required predetermined length from zero, as will be described later.

Below the positive feed rollers 6, 6, a fabric presser roller 7 and a cutter roller 8 are disposed opposite to each other as a cutting section for cutting the fabric into a desired shape. The details of these are as illustrated in FIGS. 3 to 6, and as shown in the above figures, the dough pressing roller 7 is attached to a bracket 10 which is movable forward and backward by a piston rod 9a of a fixed drive cylinder 9. is installed between both arms 10a, 10a via a support shaft 11, and both arms 10a, 10a
a is slidably supported by the fixed guide 12 so that it can move toward and away from the cutter roller 8;
As shown in FIG. 6 and further in FIGS. 7 to 9, the example shown uses two cutter rollers 8, 8, but such a double type is suitable for, for example, clothing. This is provided to accommodate differences in size such as M dimension and L dimension.
In this case, the two rollers 8, 8 have slightly different circumferential lengths or diameters depending on the size of the L dimension. Of course, in the present invention, as long as there is one or more cutter rollers 8, the number can be freely increased or decreased depending on the purpose and use. In the case of the double type shown in the figure, these cutter rollers 8, 8 are attached to a holder 14 which is swingably provided via a pivot shaft 13.
The shaft 1 is attached to the two arms 4a, 4a, respectively.
3', and the other end of the holder 14 is connected to the piston rod 15 of the driving cylinder 15.
The piston rod 15 is connected and supported by the drive cylinder 15.
One of the cutter rollers 8 can move toward and away from the fabric presser roller 7 by raising and lowering a, and if necessary, a balance weight 16 may be provided on the opposite side of the holder 14 from the arm 14a. Further, a rotating gear 17 is attached to the shaft 13' end of each cutter roller 8, 8, and at the joining position with the dough pressing roller 7, the drive shaft 18 is connected to the rotating gear 17.
It is provided with a drive gear 19 that meshes with the drive gear 19. On the circumferential surface of the cutter roller 8, a cutting cutter 20 of a desired shape is formed in a convex shape by carving out the circumferential surface of the roller. The top of the blade edge is formed by flanges 8a, 8a formed at both ends of the cutter roller 8.
The height should be such that it slightly protrudes from the circumferential surface (for example,
(approximately 0.05 mm), and the peripheral surfaces of the flanges 8a, 8a are supported on the peripheral surface of the dough pressing roller 7 during joining as shown in Figure 4, so that when both rollers 7, 8 are joined, as shown in Figure 6. As shown in FIG.
The cutter roller 8 is rotated by the gears 17 and 19 for the purpose of cutting the fabric.
When positioning the roller 8 by connecting it to the fabric pressing roller 7, in addition to smooth engagement of the gears 17 and 19, this roller 8 is
This is to provide a counter for counting the circumference of the roller, and as shown in FIG.
A piston rod 22a of the positioning cylinder 22 is removably engaged with the piston rod 22a.

Immediately below the cutting part as described above, as shown in FIG.
A cutting cutter 23 for cutting the material into individual cut pieces in the width direction based on predetermined dimensions.
is placed. The cutter 23 has a fixed lower blade 23a.
The fixed lower blade 23a is fixed with a gap in the middle of the cutting guide base plate 24, while the movable upper blade 23b is connected to the piston rod 25a of the driving cylinder 25, and the fixed lower blade 23a is By being able to open and close freely toward the blade 23a through a gap, the fabric 1 that descends on the guide base plate 24 is cut, and the cutting guide base plate 24
A cut waste suction pipe 26 is provided in an open manner through a suction box 27 directly below the cutting portion. The lower cutting blade 23a and the movable upper blade 23b are straight blades.

A transport conveyor 28 is arranged in connection with the lower end of the cutting guide base plate 24, and a suction conveyor 30 is arranged parallel to the conveyor 28 below this transport conveyor 28 via a sensing member 29 such as a pass-through phototube. The storage section 3 is placed on one side of the suction conveyor 30.
1, alignment housing portions 32 and 33 are provided below, respectively. These conveyors 28, 30 and storage sections 31, 32, 33 are for commonly automatically conveying the individual cut pieces cut into required sizes by the cutting section, and for storing them individually. Although the positional relationship is as shown in FIG. 1, the detailed structure of each part is as illustrated in FIGS. 12 to 16 and 18, and the conveyor 28 is a normal belt conveyor. The suction conveyor 30 can freely circulate in the direction of the arrow in Figure 1.
As shown in FIG. 12, a belt with small holes 30a arranged in rows on its entire surface is used, and among a pair of rollers that circulate the belt, at least one side corresponding to the discharge end of the co-conveyor 28 is used. The rollers shown in FIG.
It is arranged as illustrated in the figure. The suction roller 34 has a large number of small holes 34a lined up on its circumferential surface and is a hollow roller body, and a suction or suction/exhaust hole 37 is provided on the shaft 36 of the roller 34.
By connecting a suction or suction/exhaust pipe 39 to the same through hole 37 via a rotary joint 38, the cut pieces can be absorbed by suction, or the cut pieces can be adsorbed by suction, and the suction is stopped and the air is actively exhausted. The suction or suction/exhaust box 35 is provided with a large number of small holes 35a on the bottom surface corresponding to the conveyance surface of the suction conveyor 30, as shown in FIG. By communicating the pipe 40, the cut pieces of fabric 1 on the conveying surface are actively detached by suction or by exhaust gas supply after the suction is stopped, and the fabric 1 is dropped onto the alignment storage parts 32 and 33. This is how it was done. For the above-mentioned suction and exhaust, two valve boxes 43 and 44 are provided in an air circuit 42 by a conventional suction device 41 such as a blower, as illustrated in FIGS. 15 and 16. Intake and exhaust may be performed by switching the valves 43a, 43a. That is, in FIG. 15, each valve 43a, 44 in the valve box 43, 44
If a is placed at the solid line position as shown in the figure, suction can be performed as shown by the solid line arrow, and valve 43 can be placed at the dotted line position.
By switching the valves a and 44a, the air can be evacuated into the box 35 as shown by the dotted arrow, and after the suction is stopped, the fabric 1 can be quickly released and fallen by switching the valve and evacuating the air. It is not mandatory for

a storage section 31 for cut pieces of the fabric 1 automatically transported by the transport conveyor 28 and the suction conveyor 30;
In the alignment storage sections 32 and 33, the storage section 31 temporarily stores uncut pieces that have flaws in the fabric, but can be reused as regular-sized fabrics that can be cut by turning the flaws. For this reason, the collection box 45 is shaped like a collection box that can randomly store cut pieces, and as shown in FIGS. Adsorption roller 3 at 30
A guide plate 46 connectable to the 4th side is supported by a rotatable support shaft 48 by a rotary drive cylinder 47, so that the guide plate 46 can be connected to the 4th side to receive cut pieces as needed. The plate 46 is held by the suction roller 34
It can be tilted to the side.

As will be described later, the alignment storage sections 32 arranged in parallel directly opposite to each other below the conveyance surface of the suction conveyor 30 have no flaws in the fabric, so that the required cutting is carried out and the fabric is cut to a required size. The cut pieces, so to speak, accepted products are arranged and housed in a stacked manner, and as shown in the first figure, it consists of a stacking table 51 that can be raised and lowered via a lifting cylinder 49 guide 50, etc., and a phototube and other sensing members 52. , the sensing member 52 detects the uppermost layer of cut pieces on the stacking table 51, and the stacking table 51 is sequentially lowered for each thickness of one piece of fabric, Furthermore, as will be described later, the alignment storage section 33 that is lined up with the alignment storage section 32 is difficult to reuse even if it is cut into the required size due to the position of the fabric flaw, as will be described later. This is to separate and store cut pieces with a length shorter than the required size in order to reuse them as cut fabrics for other purposes, and for this reason, the structure can be exactly the same as the storage section 32, and the lifting cylinder 49 , a stacking table 53 that can be raised and lowered by a guide 50, and a phototube or other sensing member 52 are provided, and the stacking table 53 is similarly lowered sequentially each time one cut piece is received.

FIG. 2 shows the dimensional values in relation to the arrangement of the main members in the structure illustrated in FIG. In this invention, the length of L is the required length for cutting the long fabric 1 to the required size, in other words, the length of the desired piece of fabric 1. The length of the cut piece is L, and the sensing member 3 and both rollers 7 and 8 are set equal to this length. Further, Z represents the length from the center position of both rollers 7 and 8 to the position where the cloth is cut in the width direction by the cutting cutter 23, and L>Z. Further, in the present invention, the circumferential length of the cutter roller 8 is made to be the same as the length of the above-mentioned L.

When carrying out the cutting method according to the present invention using the above-mentioned apparatus embodiment, firstly, the object to be cut in the present invention and its contents will be explained with reference to FIG. 19. The long fabric 1 is _cut into lengths of a required fixed length L to obtain _a body fabric 55 as shown in the upper diagram in FIG _. If there are no fabric flaws such as knitting flaws in either the l ₁ or l ₂ parts, the required cutting is performed on the l ₁ part of the body fabric 55 as shown by the cutting line 56. By removing the cutting waste 57, it is possible to easily obtain the desired cut body fabric 55, and assuming that there are no fabric flaws along the entire length of the long fabric 1, continuous cutting of the long fabric 1 is possible. And cutting is extremely easy. However, in reality, it is inevitable that flaws exist in long fabrics regardless of their location. At this time, as illustrated in the upper and middle diagrams of _FIG .
In order to prevent this flaw portion 58 from being located inside the area surrounded by the cutting line 56, so-called flaw rotation is performed,
If the cutting waste 57 is located as shown in the figure, a body fabric 55 without defective parts will be obtained as shown in the upper and middle figures. In both figures, 59 indicates a cutting line in the width direction. When the continuous long fabric 1 is automatically conveyed and the above-mentioned cutting and cutting to size are automatically carried out in the middle, if there is a flawed part 58 in the l ₁ and l ₂ parts, this is ignored. If cutting is performed along the cutting line 56, the flawed part 58 may be located inside the body fabric 55 surrounded by the cutting line 56, and in this case, the body fabric 55 will be lost. Therefore, in the present invention, when there is a flaw 58 in the _l1 portion, a mark 60 to be detected is separately attached in advance, and when this is detected, the body piece 55 of the required size L is The body piece 55 is simply sorted as a rectangular body piece without being cut in the process, and is later collected and reused by turning it around for defects. When it is in _two parts, no matter how you turn it, it is impossible to position it in the cut section along the cutting line 56. In such a case, the present invention detects the flaw portion 58 using the detected mark 60 and detects the flaw portion 58 as shown in the lower part of FIG.
The cutting process is stopped, and this is collected as a rectangular cut piece along cutting lines 59, 59 as, for example, sleeve fabric 61 having a length l (l ₁ + l ₂ + α) shorter than the required fixed size L, and this The material is subjected to cutting processing using cutting lines 62 and cutting waste 63 as shown in the figure, in order to reuse the material.Such selective cutting and cutting work is continuously and automatically performed on the long fabric 1. The major feature of this method is that it is carried out in the following manner.

Next, the content of cutting according to the present invention will be explained in detail with reference to FIGS. 20 to 31. As previously explained in FIG.
After that, the material is sent out by active delivery rollers 6, 6 to a cutting section by a fabric pressing roller 7 and a cutter roller 8. At this time, the delivery roller 6 is provided with a counter for detecting flaws 58 on the fabric 1, and the cutter roller 8 has a circumferential length equal to the required fixed length L. A counter for detecting the circumferential length is provided to count the circumferential length L for each rotation so that when the circumference L is rotated once, the circumferential length L is counted up and returned to zero. Known counters can be used for these counters, but as a means for counting the circumference of the cutter roller 8, a disk is attached to the roller 8, a large number of holes are bored on the circumferential surface of the disk, and a photocell is used to measure the circumferential length of the cutter roller 8. It may be sensed and counted by a counter. In addition, in FIGS. 20 to 31, in expressing the body fabric 55 and the sleeve (or gusset) fabric 56 previously explained in FIG. 19,
For ease of identification, body fabrics 55 without any flaws 58 are simply treated as body fabrics A, B, and body fabrics 55 that can be reused by turning the flawed areas 58 are defective fabrics. The sleeve fabric 61, as shown in E, is shown as an alternative sleeve fabric 61. In addition, the sensing member 3, the active feeding rollers 6, 6, the fabric pressing roller 7, the cutter roller 8, and the cutting cutter 23 correspond to the long fabric 1, and the distance between the lengths L and Z illustrated in FIG. In FIG. 20, which is shown in a plan view and shows the starting position, for convenience of explanation, the starting position is when the front end of the body cloth is at the position of the sensing member 3, and in this position, the feeding rollers 6, 6
The cutter rollers 8 are each driven, and the respective counters of the delivery roller 6 and the cutter roller 8 are set so as to start from zero. First, in FIGS. 20 and 21, while the body material I reaches the required length L from the position of the sensing member 3 to the position of the cutter roller 8, the sensing member 3 moves the detection counter on the delivery roller 6 to zero. The presence or absence of a flawed portion 58 is detected over each part l ₁ , l ₂ , l ₁ of the body fabric eye as it passes through counting over the length of L, and the front end of the body fabric eye is detected by the cutter roller 8. When the length L of body material A passes through the sensing member 3 and the length L is counted, the counter on the delivery roller 6 is set so as to return to zero. Next, the sensing member 3 spans the length L of the body cloth following the body cloth A, and similarly counts the counters in the delivery roller 6 for each of its parts l ₁ , l ₂ , l ₁ . The presence or absence of a flawed portion 58 is detected by using this method, as shown in FIGS. 22 and 23. When the length L of the body cloth is counted up in this way, the counter returns to zero again, and the defective body cloth that has a flawed part 58 following the body cloth in the _L1 portion is also counted up, as shown in FIG. Over the length L,
The flaw portion 58 of each portion l ₁ , l ₂ , l ₁ is detected, and as shown in FIG. It counts up the value L and returns to the zero position again. By the combination of the sensing member 3 and the flaw detection counter on the side of the active feeding rollers 6, 6, the required fixed length L length of the passing fabric 1, each l ₁ in the same L length, To detect the presence or absence of the flawed portion 58 in the l ₂ and l ₁ portions, the counter side first counts the length l ₁ , then the length l ₁ +l ₂ , and then the length l ₁ +l ₂ +l ₁ . That's what we do.
Next, as shown in FIGS. 24 to 26, when detecting a flaw on a sleeve fabric having a flaw 58 at the _l2 portion of the required length L, the sensing member 3, the delivery roller 6 When detecting the l ₁ and l ₂ parts in the same way using the counter, and detecting a flaw part 58 in the l ₂ part as shown in the figure, the counter of the delivery roller 6 indicates that the length is shorter than the required fixed length L. When the length l is counted, the counter returns to zero, and the detection of the sleeve fabric N whose length l is shorter than the required length L is completed, and the rest is as shown in Fig. 26. The next step is to sense and detect defective body materials. Regarding this defective body material H, as mentioned above, it is exactly the same as the cases of body fabrics A, B, and defective body fabric C, and the sensing member 3 is According to the count of the flaw detection counter in the positive feed roller 6, if there is no flaw at all, or if there is a flaw 58 in the _l1 portion, the length is regulated as the required length L and is fed out. , l ₂ portions with flaws 58 are subject to selection and regulation as fabrics for sleeves or lintels with a length l shorter than the required fixed size L. As described above, while the long fabric 1 is automatically sent out, the fabric 1 is sequentially and selectively and automatically sorted into body fabric and sleeve fabric based on the presence or absence and position of flawed parts. During this time, when the front end of the first body cloth eye shown in FIG. The detection counter for length L (same as length L) also starts counting from the zero position, and the same roller 8 rotates once and reaches length L
When counting up, that is, body fabric 1 of length L
As shown in Figures 20 and 21, when the material moves by a length L from the position of the sensing member 3 to the position of the cutter roller 8, since no flaws 58 are detected on this body material, the material pressing roller 7 remains in pressure contact with the circumferential surface of the cutter roller 8 via the flange 8a through its drive cylinder 9, and as a result, the body material is rotated by the rotation of the roller 8 as shown in FIG. As a result of the rotation of the cutting cutter 20 formed on the circumference, the required cutting is performed on the body fabric along the cutting line 56 between it and the fabric pressing roller 7, as shown in FIG. Furthermore, due to the rotation of the cutter roller 8,
When the counter of the roller 8 starts counting from zero again and counts the length Z, that is, when the front end of the body cloth reaches the position of the cutting cutter 23 as shown in FIG. 23 is activated, and if the cloth 1 continues at the front end of the body cloth 1, cutting in the width direction along the cutting line 59 is performed here. After that, when the cutter roller 8 finishes counting the circumference L by its counter, the front end of the body cloth I following the body cloth I reaches the position of the cutter roller 8 from the position of the sensing member 3, and the body cloth I reaches the position of the cutter roller 8. Since there is no flaw 58 on the body material 1, the same cutting is performed by rotating the cutting cutter 20 while the material pressing roller 7 is in pressure contact with the cutter roller 8. Next, the counter of the cutter roller 8 starts counting from the zero position again, and when the length Z is counted, the front end of the body cloth reaches the position of the cutting cutter 23, as shown in FIG.
By operating the cutter 23, the body parts A and B can be separated along the cutting lines 59. The defective body material C, on which a flaw portion 58 was detected in the L ₁ portion following the body material cutter, is similarly fed out L length, and when the front end reaches the position of the cutter roller 8, the flaw portion 58 is detected. At the same time, the fabric pressing roller 7 is moved backward and the connection with the roller 8 is left open, so that the defective fabric is not cut and is cut into an uncut piece having a rectangular shape with a predetermined length L. It will be sent out as fabric. Therefore, when the counter in the cutter roller 8 starts counting from zero and counts the length Z, the defective fabric is cut off by the cutting cutter 23 as shown in FIG.
The front end advances to the position , and the cutter 23 is operated to cut off the body cloths C and C. Regarding the sleeve fabric 2 following the body fabric C, similarly to the body fabric C, detection over the l ₁ and l ₂ portions is sequentially performed by the sensing member 3 and the counter in the active feeding roller 6. However, there are scratches on the l ₂ part 5
8, this fabric 2 cannot be used as body fabric, so this part is sent out as sleeve fabric 2 with a length l shorter than the standard length L, as shown in Figure 27. Upon this detection, the fabric pressing roller 7 is moved backward from the cutter roller 8, so the sleeve fabric 2 is not cut, and the front end of the fabric 2 is cut as the cutter roller 8 feeds out the Z length as shown in FIG. When the cutter 23 reaches the cutting cutter 23, the cutter 23 separates the defective fabric from the fabric, and the counter in the cutter roller 8 counts the length l from the position of the cutting cutter 23 (where l> Z), that is, as shown in FIGS. 29 to 30, the front end of the sleeve fabric 2 advances by a length l from the position of the cutter roller 8,
At the same time, the front end of the following defective fabric E reaches the position of the cutter roller 8, and at this time, since a flaw 58 is detected in the _l1 portion of the same fabric E, the fabric presser roller 7 is moved to the cutter roller 8. 8, the fabric feeding is stopped by stopping the driving of the active feeding rollers 6, 6 in this state. On the other hand, when the circumferential length detection counter in the cutter roller 8 counts up the circumferential length L, the delivery rollers 6 are driven again and the fabric delivery is resumed. That is, as shown in FIGS. 29 to 30, when the counter in the cutter roller 8 starts counting from zero and counts up the length Z, the front end of the defective fabric is at the cutting cutter 23 position. When the cutter 23 reaches the length, the sleeve fabric 2 and the defective fabric 5 are separated, and the counter of the cutter roller 8 reaches the circumference length L.
When counting up, as shown in FIGS. 30 to 31, the body fabric with no flaws 58 following the defective body fabric is fed out by a required length L, and its front end is When the cutter roller 8 position is reached and it is detected that there is no flaw part 58, the fabric pressing roller 7 is connected to the cutter roller 8, so that the cutting cutter 20 can cut the body fabric as required. A judgment will be made. As for the sleeve fabrics 1 and 2 shown in FIG. 31, only the length 1 of the sleeve fabric 2 described above is delivered and the front and back cutting thereof is performed.

Of course, in the cutting details shown in FIGS. 20 to 31, in the long fabric 1, the flawed portion 58 is simply located along its length, as shown in the figure. Only the mark 60 is attached in advance, and there is no distinction between the body fabric 55 and the sleeve fabric 61. In the present invention, a sensing member 3 for detecting the sensed mark 60, a counter for dimensionally detecting the flaw portion 58 on the positive feeding roller 6, and further a predetermined length L from the sensing member 3 are provided. The flaws on the progressing long fabric 1 are detected by the combination of the installed cutter roller 8, a circumferential length detection counter provided on the roller 8, and a circumferential length L of the roller 8 that is the same as the required fixed size L. The position of 58 is detected, and this is used to determine whether the body fabric has a required length L and has no flaws, the defective body fabric that can be reused as body fabric by turning the flaws later, or the body fabric which has defects. 3 short length L fabrics that are not used as fabrics but can be used as sleeve fabrics
A series of tasks in which the person selects and separates the waste, automatically cuts and separates the waste, and then automatically performs the necessary cutting process can be carried out easily.

As shown above, each of the cut pieces formed as body material I..., defective body material C..., and sleeve material N... are placed in different positions according to their contents. Automatic transportation and separate storage are convenient for subsequent processing steps. Therefore, in the present invention, FIGS.
An automatic conveyance/accommodation mechanism as illustrated in FIGS. 12 to 16 is used. That is, when the front and rear parts are cut by the cutting cutter 23 along the cutting lines 59, 59, as shown in FIG. 32 to FIG. Regarding B and C, the front end of the body fabric A, which has passed through the cutting section by the fabric pressing roller 7 cutter roller 8, reaches the position of the cutting cutter 23, and the excess fabric portion 1' is left at this front edge as shown in FIG. 32. If it is, cutter 23
The front end is cut in the width direction, and the fabric portion 1' is removed. In this way, as shown in FIG. 33, the body material cut along the cutting line 56 by the subsequent feeding of the body material 56 advances on the cutting guide plate 24 along its slope, and as shown in FIG. 34. When the front end of the body material I reaches the position of the cutting cutter 23 and is cut along the cutting line 59, the body material A and B are separated, and the cutting waste 57 remaining outside the cutting line 56 on the body material A is removed. The body material is sucked and removed by a suction pipe 26 provided on the cutting guide base plate 24 via a suction box 27, and is transferred from the cutting guide base plate 24 onto the transport conveyor 28, and is transferred to the conveyor 28 when the conveyor 28 is operated. Thereafter, the body fabric is sequentially cut in the order of A and C as shown in FIG. 35, and each piece of fabric is conveyed by the conveyor 28. In the case of the sleeve fabric 2, the fabric following the defective body fabric 3 is shown in FIG. 36, and both cases are the same. At this time, as shown in FIGS. 35 and 36, in the case of defective body fabric C or sleeve fabric D, the fabric pressing roller 7 is separated from the cutter roller 8.
As a result, these fabrics C and D are not cut.

In the process of sorting and storing the cut body fabric (A) with no flaws, which was cut from the long fabric 1 as described above, the defective body fabric (C) which could not be cut due to the flaws, and the sleeve fabric (D). As shown in FIG. 37, when the sensing member 29 detects the body material conveyed by the conveyor 28, the suction conveyor 30 is caused to circulate in the direction of the arrow. At the same time, the suction roller 34 and the suction box 3
A suction mechanism such as 5 is also driven, and at the same time, although not shown, a counter for the number of roller rotations provided on the roller side of the suction conveyor 30 starts counting from zero. Then, as shown in FIG.
The body material I is attracted to the suction conveyor 30 and rotates to the bottom side of the conveyor, and as shown in FIG. Therefore, when the count of the rotation speed counter provided on the roller side of the suction conveyor 30 reaches a predetermined count by detecting that there are no flaws on the body material, the suction conveyor 30 is stopped and the same operation is performed at the same time. By stopping the suction at the suction roller 34 or suction box 35 in the conveyor 30, the body articles fall onto the stacking table 51 and are successively stacked and stored. At this time, the suction roller 34 in the suction conveyor 30
On the suction box 35 side, the 12th
As illustrated in FIGS. 1 to 16, in addition to suction, it is also possible to actively exhaust the air after stopping suction to smoothly and quickly remove and fall the fabric. At this time, the stacking table 51 is movable up and down as described above, and when the table 51 is raised and lowered, the sensing member 52 senses the fabric on the top layer of the table, and the stacking table 51 is moved up and down for each layer of fabric. Even if it is lowered sequentially, platform 5
1 to the bottom surface of the conveyor 30 and stack them,
The platform 51 may then be lowered to the old position. On the other hand, the defective body material C, which has the required size L as a body material and has a flaw 58 in the _l1 portion, is stored in the storage section 31 as shown in FIG. The sensing member 29 detects this defective fabric, and the guide plate 46 in the storage section 31 is rotated and tilted toward the suction roller 34 side of the suction conveyor 30 via the driving cylinder 47, etc., and at this time, the suction conveyor The suction at 30 is stopped, and the body material on the transport conveyor 28 is moved to the suction conveyor 30 guide plate 4 in a non-suction state.
6 and into the collection box 45, the conveyor 30 is stopped according to the count number of the timer or counter on the conveyor, and the guide plate 46 is also returned to its old position. The defective fabric is then turned for flaws so that the flawed part 58 is located at the position of the cutting waste 57 in the cut part, and is then separately cut.

Further, in the case of sleeve fabrics 2, similarly to body fabrics 1, they are stacked and stored on the stacking table 53 in the alignment storage section 33 that is lined up with the alignment storage section 32 via the transport conveyor 28 and suction conveyor 30.

In the embodiments described above, from the elongated fabric 1 made of the cylindrical knitted fabric, for example, the body fabric 55 of a shirt, as illustrated in FIG.
We have described the case where the sleeve fabric 61 etc. are cut, but as illustrated in FIG.
The present invention can be similarly applied to the case where the cloth for lint 61 is cut out. That is, as shown in the first row of the figure, a pair of body fabrics 55, 55 are cut along a cutting line 56 from a piece of cut fabric with a required length of _{l 1} +l ₂ +l ₃ +l ₂ +l 1 =L. When cutting, there are no flaws 5
In the first diagram without 8, the method of the present invention,
Cutting to size and shredding can be similarly achieved by the device, and the cut waste 57 can also be collected by suction. Therefore, these body fabrics 55 can be stored in exactly the same way on the stacking table 51 of the alignment storage section 32, as shown in FIG. At this time, if the cut waste 57 is difficult to be collected by suction due to its shape, size, etc., the fourth
As illustrated in FIG. 2, by forming a non-adsorption portion 34b on the circumferential surface of the suction roller 34 of the suction conveyor 30, the cut waste 57 is removed from the suction roller 34 position as shown in the example (43rd
(Illustrated in the figure) It is also possible to drop and collect them into a separate collection box 64. As shown in the second row of Figure 41,
If there are flaws 58, 58 in the l ₁ and l ₁ portions at both the left and right ends of the required size L, this is considered a defective fabric that can be turned into a rectangular shape with the required size L that is not cut. Cut as pieces of dough, 4th
This can be randomly collected in the storage section 31 shown in FIG. 3, processed after the fact, and reused as body fabrics 55, 55. As shown in the third row of FIG. If there is a flaw 58 in the l ₂ , l ₂ part of the figure, it cannot be used as a body fabric, so it is a lint fabric with a length l shorter than the required specified size L. 61, it is necessary to cut a rectangular piece of fabric to a length l, and then separately cut and collect a plurality of gossamer pieces 61a. In this way, the method and apparatus of the present invention can be applied to various types of cut fabrics depending on the purpose and use.
Of course, the fabric 1 does not matter whether it is a knitted fabric or a woven fabric, and can be applied whether it is a cylindrical body or a single piece. are the same, and the conveyor 28 and the adsorption conveyor 30 are the same.
The fabric feeding speed in
It is preferable that the feed speed of the suction conveyor 30 is made larger than that of the transport conveyor 28.

The present invention is as described above, and in contrast to conventional fabric cutting, a continuous length of fabric is moved in one direction, and a desired cut is made according to the presence or absence of knitting flaws, weave flaws, etc. in the fabric and their positions. The fabric is automatically sorted into pieces of fabric that can be cut to a certain length, pieces of fabric that can be cut by flaw processing, and pieces of fabric that are shorter than the required length but can be cut for other purposes. By immediately cutting the pieces of fabric that can be cut to the required length, and allowing other pieces of fabric to be cut individually through post-processing, it eliminates fabric loss and is extremely efficient. This method is extremely advantageous in that it can produce large quantities of cut fabric pieces. Compared to the conventional method of stretching, laminating, cutting to size, and cutting the fabric, the fabric is inspected for flaws, rotated, laminated one by one, and then cut. All you have to do is attach a detection mark to the flawed part of the fabric while moving it, and the rest is automatic flaw detection along the moving path and appropriate selection of the fabric piece.
Since the desired pieces of fabric are processed continuously depending only on whether or not each selected fabric is cut, the work efficiency is extremely high, resulting in labor savings and speeding up. At this time, by directing the flawed part of the fabric to the position of the cutting waste generated during cutting, it is possible to use the fabric without wasting it, and by automatically transporting and separately collecting these different pieces of fabric,
Post-process transition and division of labor are easy.

In addition, in the present invention, as a device, a sensing member 3 for detecting flaws, positive feed rollers 6, 6, a fabric presser roller 7 and a cutter roller arranged at a desired length L from the sensing member 3 are used. By using only the cutting section according to 8, the cutting section placed in front of the cutting section, the automatic conveyance following the cutting section, and the sorting and storage equipment,
A series of automatic operations such as detecting flaws, sorting fabric pieces based on the detection of flaws, determining whether to cut or not and cutting and separating are carried out smoothly, and counters are provided on the positive feed roller 6 and cutter roller 8 sides as a means for measuring dimensions. This makes it possible to determine the length of a piece of fabric without error, and it can be designed more compactly than conventional cutting equipment.
This method is excellent because it allows cutting fabric pieces to be obtained more quickly and efficiently than from long fabrics.
