Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves cutting a continuous strip of fabric into cut pieces for each required dimension, and providing a desired cut shape at a predetermined position of each cut piece. The system automatically selects and cuts the fabric according to the presence or absence of fabric flaws that occur during the manufacturing process and their location, and also selects and accommodates each type of cut piece. related to the provision of new means.

As a conventional means for cutting a long fabric made of various knitted fabrics or woven fabrics into individual cut pieces and giving each cut piece a desired cut shape at a desired position, for example, as is known, in the case of using a spreading method, for example, First, the fabric is stretched and laminated, and then it is cut into pieces of specified size. Each layered fabric cut into pieces is further inspected for fabric flaws due to knitting or weaving, and the required flaw treatment is carried out. While doing this, the sheets are stacked one by one, and then cut with a cutting cutter.
There are problems in that many manual pretreatment steps are required, the work efficiency is extremely low, and a lot of labor is required.

The present invention solves these problems by feeding a long continuous strip of fabric into a work path in a stretched manner, checking for the presence and location of flaws, and determining whether or not cutting is appropriate based on this. Those that can be judged and cut are cut and automatically arranged and stored in a fixed position as cut pieces of the required size, and those that are not cut properly can be turned around and reprocessed later depending on the location of the flawed part. Store cut pieces of a certain required size, or those that are impossible or difficult to turn, as cut pieces shorter than the required size so that they can be used for other purposes. This series of operations can be performed automatically, and its special feature is that it cuts a continuous strip of fabric into the required size in the width direction, and also cuts each cut piece. In order to cut the fabric into the desired shape, the presence or absence and location of fabric flaws within the required dimensions are detected, and if there are no fabric flaws, a cutter is used to cut the fabric into the desired shape on the fabric presser roller and roller circumferential surface. The cut pieces are cut into a desired shape by passing between the cutter roller that has been formed, and are cut into pieces of a predetermined size in front of this cutting position, and the cut pieces are automatically conveyed to a predetermined position and arranged and stored. If the fabric has a flawed part, it is not cut as described above, but is cut into a cut piece of a predetermined size or a cut piece shorter than the predetermined size according to the position of the flawed part of the fabric, and these uncut cut pieces are cut into pieces that have already been cut. The cut pieces are automatically transported and stored or arranged and stored in separate positions, and their unique feature is that they are continuous long strips and have markings to be detected on the sides corresponding to the fabric flaws. an automatic feeding path for the fabric, which is equipped with an automatic feeding path for the fabric; an active feeding roller that is placed at the front end of the path and is equipped with a counting means for detecting fabric flaws; a fabric pressing roller that is placed in front of the roller, and the peripheral surface of the roller a cutting section formed with a cutting cutter and a cutter roller equipped with roller circumference counting means; a cutter for cutting the fabric in the width direction disposed in front of the cutting section; and a cutter disposed in front of the cutter. Moreover, it is comprised of an automatic conveyance path that commonly conveys cut pieces and uncut pieces, and storage or alignment storage sections for each cut piece, which are arranged at different positions on the conveyance path.

A suction conveyor (30) is arranged parallel to the conveyor (28), and a storage section (31) is provided on one side of the suction conveyor (30).
, and alignment accommodating portions (32) and (33) are provided below, respectively. These conveyors (28) (30) and storage units (31) (32) (33) commonly and automatically transport the individual cut pieces cut into required sizes by the cutting unit, and also individually store them. It is for the purpose of
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 Fig. 1, and the suction conveyor (30) has small holes (
80a) are arranged in a row, and among the pair of rollers that circulate the belt, the least one roller corresponding to the discharge end of the common conveyor (28) is used as a suction roller (34). Also, the alignment housing part (32) (32
) A suction or suction/exhaust box (35) is installed inside the conveyor surface (30) facing the conveyor (30) as shown in FIGS.
It is arranged as illustrated in the figure. The suction roller (34
) has a large number of small holes (84a) lined up on the circumferential surface of the roller and is a hollow roller body, and the shaft (34) of the roller (34) is

If you switch (44a), the box (
35), and after stopping the suction, switching the valve to evacuate allows the dough (1) to quickly fall off and fall, but these are not essential in the present invention.

A storage section (31) for cut pieces of the fabric (1) automatically transported by the transport conveyor (28) and suction conveyor (30).
, in the alignment housing parts (32) and (33), the housing part (31
) is used to temporarily store uncut pieces that have flaws in the fabric, but can be reused as regular-sized fabric that can be cut by turning the flaws.For this reason, the cut pieces are randomly stored. It is said to be shaped like a collection box,

can be tilted toward the suction roller (34).

As will be described later, the alignment storage section (32), which is arranged directly in parallel below the conveyance surface of the suction conveyor (30), is free from flaws in the fabric, so that the required cutting is carried out and the material is cut to the required size. The cut pieces, so to speak, passed products are arranged and housed in a stacked manner, and as shown in the first figure, the lifting cylinder (4
9) A stacking table (51) that can be raised and lowered via a guide (50) etc.
) and a phototube or other sensing member (52), and the sensing member (52) senses the uppermost layer of the laminated cut pieces on the lamination table (51), and detects the thickness of each piece of fabric. To,
The stacking table (51) is designed to be lowered in sequence, and the alignment accommodating section (33) aligned with the alignment accommodating section (32) is arranged as required depending on the position of the fabric flaw, as will be described later. It is difficult to reuse even if it is cut to a certain size, so in order to reuse it as cut fabric for another purpose, it is used to separate and store cut pieces with a length shorter than the required size. Therefore, its structure can be exactly the same as the housing part (32), and the lifting cylinder (49),
a stacking table (53) that can be raised and lowered by a guide (50);
It is equipped with a phototube or other sensing member (52), and similarly, a stacking table (53) is sequentially lowered each time one cut piece is received.

Figure 2 shows the dimensions of the arrangement of the main components in the structure shown in Figure 1. (8) shows the length to the center position, and the length of L is the length of the long fabric (1
) is cut to the required size, in other words, it is the length L of the desired cut piece, and the sensing member (3) and both rollers (7) (8) is set equal to the length of this L.

Further, Z represents the length from the center position of both the 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.

In carrying out the cutting method according to the present invention using the above-mentioned apparatus embodiment, firstly, the object to be cut according to the present invention and its contents will be explained with reference to FIG. 19. (1) is cut into lengths of the required fixed length L to obtain body fabric (55) as shown in the upper diagram in Fig. 19, and in this body fabric (55),
Within a predetermined dimension where 1+l2+l1=L, that l
When there are no fabric flaws such as knitting flaws in any of the parts 1 and 12, the part 11 shown in the figure of the body material (55) is cut as indicated by the cutting line (56), and the cutting waste is removed. By removing (57), the desired cut body fabric (55) can be easily obtained, and the long fabric (1
), it is extremely easy to continuously cut and cut it, assuming that there are no flaws in the fabric over its entire length. 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.
As shown in the figure, cut scraps (5
If the key is located in the part 7), 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 a continuous long piece of fabric (1) is automatically conveyed and cut to size as described above, a flaw (5
8), if you ignore this and cut along the cutting line (56), the flawed part (58) will be cut along the cutting line (56).
) If the body fabric (55) is located inside the body fabric (55) surrounded by ), mark this in advance as the detected mark (6
0) is attached separately, and when this is detected, the body piece (55) of the required fixed size L is simply sorted as a rectangular body piece (55) without being cut, and later collected. The aim is to reuse it by turning it around, and furthermore, in the upper and middle diagrams of Figure 19, the flaw part (58) is l2
If the flaw is on the cutting line (
56) is impossible. In such a case, the present invention detects the flawed part (58) using the detected mark (60) as shown in the lower part of FIG. 19, and stops cutting the body material (55).
This is set to a length l (l1+l2+α
), for example, the cutting line (59) (5
9) is collected as a rectangular cut piece, which is then subjected to cutting treatment using cutting lines (62) and cutting waste (63) as shown in the figure, in order to reuse it. The major feature is that cutting and cutting operations are performed continuously and automatically on a long piece of fabric (1).

Next, the content of cutting according to the present invention will be explained in detail with reference to FIGS. 20 to 81. As previously explained in FIG. 1, the long fabric (1) is continuously fed out via a belt conveyor (2), and is actively fed out via a formwork (5) and guide rollers (4) (4). The fabric is sent to the cutting section by the fabric presser roller (7) and cutter roller (8) by the rollers (6) and (6).

At this time, the delivery roller (6) is provided with a counter for detecting flaws (58) in the fabric (1), and the cutter roller (8) has a circumferential length that is equal to the required fixed size L. In addition, the roller is equipped with a circumferential length detection counter that counts up the circumferential length L every time the roller (8) rotates once and returns to zero. It is provided. Known counters can be used as these counters, but as a means for counting the circumference of the cutter roller (8), a disk is attached to the roller (8) and a large number of holes are bored in the circumferential surface of the disk. , this may be detected by a phototube and counted by a counter.

In addition, in FIGS. 20 to 31, when expressing the body fabric (55) and the sleeve (or gusset) fabric (56) previously explained in FIG. 19, for ease of differentiation,
The body fabric (56) without any flaws (58) can be simply used as body fabric (a) and (b), and the body fabric (55), which can be reused by turning the flawed area (58) around, is considered defective body fabric (58). c) As in (e), the material to be further used as sleeve fabric (61) is shown as an alternative sleeve fabric (d). In addition, the sensing member (3), the active feed roller (6) (6
), the fabric pressing roller (7), the cutter roller (8), and the cutting cutter (23) are used to cut the long fabric (1), respectively.
Correspondingly, the front end of the body fabric (A) is shown in a plane between the lengths L and Z illustrated in FIG. 2, and for convenience of explanation, in FIG. Parts (3
) is the starting position, and at this position, the feed rollers (6), (6) and cutter roller (8) are respectively driven, and the feed roller (6) and cutter are driven.
Each counter in the roller (8) is placed so that it starts from zero. First, in FIGS. 20 and 21, while the body fabric (A) reaches the position of the cutter roller (8) from the position of the sensing member (3) through the required length L, the sensing member (3) , the presence or absence of flaws (58) in each part of l1, l2, l1 of the passing body fabric (a) is determined by counting from zero to the length of L on the detection counter in the delivery roller (6). When the front end of the body material (A) reaches the cutter roller (8), the length L of the body material (A) passes through the sensing member (3), and the length L is counted. When this occurs, the counter on the delivery roller (6) is set so that it returns to zero. Next, the sensing member (3) extends over the length L of the body fabric (B) following the body fabric (A), and similarly detects the pressure on the delivery roller (6) for each of its parts l1, l2, and l1. The presence or absence of a flawed portion (58) is detected through the count of the counter, as shown in FIGS. 22 to 28. In this way, if you count up the length L of the body fabric (B), the counter will return to zero again and the body fabric (B) will be counted up.
The defective fabric (c) which has the flawed part (58) in the l1 part following B) also has flawed parts (58) in each part l1, l2, l1 over its length L as shown in Fig. 23. As shown in Fig. 24, when this defective fabric (c) passes the sensing member (3), the counter in the delivery roller (6) also counts up the length L and starts counting again. It returns to the zero position. Note that the sensing member (3
) and the counter for detecting flaws on the positive feeding roller (6) (6) side, the required fixed length L length of the passing fabric (1) and each l length in the same L length are detected.
To detect the presence or absence of a flaw (58) in portions 1, 12, and 11, the counter first counts the length 11, then the length 11+12, and then 11+12+11. Then the 24th
l at the required fixed length L as shown in Figures to Figure 26.
When detecting flaws on the sleeve fabric (d) which has flaws (58) on two parts, the sensing member (3) and the counter of the delivery roller (6) similarly detect parts l1 and l2. However, as shown in the figure, there is a flaw (58
) is detected, and when the counter of the delivery roller (6) counts a length l shorter than the required fixed length L, the counter returns to zero and the length shorter than the required fixed length L is detected. After the detection of the sleeve fabric (D) of item 1 is completed, the next step is to sense and detect the defective body fabric (E) as shown in FIG. As mentioned above, this defective body fabric (E) is exactly the same as the case of body fabrics (A), (B), and defective body fabric (C), and the following long fabrics are continuously sent ( In contrast to 1), depending on the count of the flaw detection counter in the sensing member (3) and the active feeding roller (6), if there is no flaw at all, or if there is a flaw (
Items with 58) are sent out as regulations with the required length L, and items with flaws (58) on the l2 portion are shipped for sleeves with a length l shorter than the required size L. This resulted in the selection and regulation of cloth for lint (2).

As described above, while the long fabric (1) is automatically fed out, the fabric (1) is sequentially inspected depending on the presence or absence and position of the flawed part.
It will be selectively and automatically sorted into body fabric and sleeve fabric, and the front edge of the body fabric (A) shown in FIG. When the cutter roller (8) is reached, the cutter roller (8) is driven and rotated and the cutter roller (8) is driven to rotate.
The counter for detecting the circumference L (same as the fixed size L) provided in roller (8) also starts counting from the zero position, and
) rotates once and counts up the length L, that is, when the body material (1) of length L moves from the position of the sensing member (3) to the position of the cutter roller (8) as shown in Figures 20 and 21. When the body fabric (A) is moved by a length L to the body fabric (A), there are no flaws (58) detected at all, so the fabric presser roller (7) moves through its drive cylinder (9) to the cutter roller ( 8) through the flange (8a), and as a result, the body fabric (a)
As shown in Fig. 6, due to the rotation of the cutting cutter formed on the circumference due to the rotation of the roller (8), the cutting cutter formed on the periphery is cut between the fabric pressing roller (7) and the body fabric (A) as shown in Fig. 28. As shown, the required cutting is performed along the cutting line (56).

Furthermore, due to the rotation of the cutter roller (8), the cutter roller (8)
) counter starts counting from zero again and the length Z
When the front end of the body material (A) reaches the position of the cutting cutter (23) as shown in FIG. 22, the cutting cutter (23) is activated and the body material (1) is
), if the fabric (1) continues at the front end of the fabric (1), it is cut in the width direction along the cutting line (59). After that, when the cutter roller (8) finishes counting the circumference L further by its counter, the front end of the body fabric (b) following the body fabric (a) moves from the position of the sensing member (3) to the cutter roller (8). The position is reached, and the body material (b)
Since there is no flaw (58) at all, the cutter roller (8) of the fabric presser roller (7) is removed as in the case of the body fabric (1).
), similar cutting is performed by rotating the cutting cutter (20). Next, the counter of the cutter roller (8) starts counting the force again from the zero position, and when the length Z is counted, the front end of this body material (b) is at the position of the cutting cutter (23), as shown in Fig. 28. When the cutter (23) is operated, the body fabrics (a) and (b) are separated along the cutting line (59).

Continuing from the body fabric (b), there is a flaw in the l1 part (58)
The detected defective fabric (c) is similarly fed out a length of L, and when the front end reaches the cutter roller (8) position, the flawed portion (58) is detected and the fabric pressing roller (
7) is moved back to leave the connection with the roller (8) open, so that the defective fabric (c) is cut into a rectangular shape with a required length L without being cut. It will be sent out as body material. Therefore, when the counter in the cutter roller (8) starts counting from zero and counts the length Z, the defective material (c)
As shown in Figure 5, the front end advances to the position of the cutting cutter (23), and the cutter (23) is operated to separate the body fabrics (b) and (c). In the sleeve fabric (d) following the body fabric (c), similarly to the body fabric (c), the sensing member (3) and the counter in the active feed roller (6) sequentially apply pressure to the l1 and l2 portions. As the detection continues, this fabric (D) cannot be used as a body fabric due to the flaw (58) in the L2 area, so as shown in FIG. As d), the material is fed out with a length L shorter than the fixed length L, and at the same time as this detection, the fabric pressing roller (7) is moved back from the cutter roller (8), so that the sleeve fabric (
D) is not cut, and as shown in Fig. 28, the front end of the fabric (D) reaches the cutting cutter (23) as the cutter roller (8) feeds the Z length, and the cutter (23), the defective fabric (c) is separated, and the counter in the cutter roller (8) counts the length l from the position of the cutting cutter (23) (provided that l>Z) That is, as shown in FIGS. 29 to 80, the front end of the sleeve fabric (d) advances by a length l from the position of the cutter roller (8), and at the same time, the following defective fabric The front end of (E) will reach the position of the cutter roller (8), and at this time, there will be a flaw (58) on the L part of the same fabric (E).
Since the fabric pressing roller (7) is retracted from the cutter roller (8) due to the detection of be done. On the other hand, when the length of the circumference L is counted up by the circumference detection counter in the cutter roller (8), the feed roller (6) (6
) is driven again to restart fabric delivery. That is, the 29th
As shown in FIGS. 80 to 80, when the counter in the cutter roller (8) starts counting from zero and counts up the length Z, the front end of the defective material (E) reaches the cutting cutter ( 23) When the position is reached,
The sleeve fabric (d) and the defective fabric (e) are separated by the same cutter (23), and the cutter roller (8)
) counts up the circumference L, the 8th
As shown in Figures 0 to 81, the body fabric (F) without any flaws (58) following the defective body fabric (E) is fed out by a required length L, and the front end is passed through the cutter. Upon reaching the roller (8) position and detecting that there are no flaws (58), this body fabric (
For (f), the required cutting is performed by the cutting cutter (20). Note that the sleeve fabrics (chi) and (li) shown in Fig.
As in (d), only the length l is sent out and the front and back cutting is performed.

Of course, in the cutting contents shown in Figs. 20 to 81,
In the long fabric (1), simply over the length direction,
Corresponding to the flawed portion (58), a detection mark (60) is attached in advance as shown in the figure, so that the body fabric (56) to the sleeve fabric (61) can be distinguished. It doesn't exist. In the present invention, the sensed mark (60)
a sensing member (3) for detecting the damage, a counter for dimensionally detecting the flaw portion (58) on the active feeding roller (6), and a counter for dimensionally detecting the flaw portion (58) on the active feeding roller (6), and furthermore, by placing a required length L from the sensing member (3). Installed cutter roller (8), same roller (8)
The position of the flaw part (58) in the progressing long fabric (1) is detected by the combination of the circumferential length detection counter provided in the roller (8) and the circumferential length L of the same roller (8) that is the same as the required fixed size L. At the same time, this can be used to produce body fabrics with a required length L that have no flaws at all, defective fabrics that can be reused as body fabrics by turning the defects even if they have defects, and furthermore, fabrics that cannot be used as body fabrics. 8 short length L fabrics that 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 cut piece formed as body fabric (A)..., defective body fabric (C)..., and sleeve fabric (D)... Automatically transporting each item to a different location depending on its content and storing it separately is convenient for subsequent processing steps. For this reason, the present invention uses an automatic transport and storage mechanism as previously explained in FIGS. 1, 10, and 11, and further in FIGS. 12 to 16. In other words, the cutter (23) cuts the front and back along the cutting lines (59) (59).
As illustrated in FIGS. 82 to 86, the second
Regarding the body fabrics (A), (B), and (C) explained below in Figure 0, the front end of the body fabric (A) that has passed through the cutting section by the fabric presser roller (7) and cutter roller (8) is cut by the cutting cutter ( 23) When the position is reached and there is an excess fabric part (1)' at the front end as shown in Figure 82, the front end is cut in the width direction by the cutter (23) and the fabric part (1)' are excluded. In this way, as shown in Figure 88, the cutting line (56) is cut by sending out the subsequent body material (B).
The body fabric (A) that has been cut is cut using the cutting guide plate (2).
4) The front end of the body fabric (b) reaches the cutting cutter (23) position and is cut along the cutting line (59) as shown in Figure 84. The body fabrics (a) and (b) are separated, and the cutting waste (57) remaining outside the cutting line (56) in the body fabric (a) is removed from the suction pipe (26) provided on the cutting guide base plate (24).
The body fabric (A) is transferred from the cutting guide base plate (24) onto the conveyor (28), and transported by the operation of the conveyor (28). Then, in the same manner, the body fabrics (b) and (c) are sequentially cut in the order shown in FIG. 85, and each piece of fabric is transported by the conveyor (28). In the case of the sleeve fabric (d), the fabric following the defective body fabric (c) is shown in FIG. 86, but the same is true for both. At this time, as shown in Figures 85 and 86, in the case of defective fabric (c) or sleeve fabric (d), the fabric presser roller (7) is separated from the cutter roller (8), which causes these No cutting is performed on the fabric (c) or (d).

The cut body fabric (A) with no flaws cut from the long fabric (1) as described above, the defective body fabric (C) that was not cut due to the flaws, and the sleeve fabric (Ni). ), as shown in FIG. ) is circulated in the direction of the arrow, and the suction mechanism including its suction roller (34), suction box (35), etc. is also driven, and at the same time, although not shown, the rollers provided on the roller side of the suction conveyor (30) are rotated. The number counter starts counting from zero.

Next, as shown in FIG. 88, the body fabric (A) is sucked by the suction collector (30), rotates to the bottom side of the conveyor, and is transferred to the eighth
As shown in Figure 9, this body material (a)
), that is, the sensing member (3) mentioned earlier.
When the number of revolutions counter provided on the roller side of the suction conveyor (30) reaches a predetermined count through detection that there are no flaws on the body fabric (A), the suction comparer (30) is activated. At the same time, the suction roller (34) or suction box (35) of the conveyor (30) is stopped, so that the body fabric (a) falls onto the stacking table (51) and is successively stacked and stored. Ru. At this time, the suction roller (34) to suction box (35) side of the suction conveyor (30) not only performs suction, but also actively performs Exhaust may be performed to facilitate and speed up the detachment of the dough. At this time, the laminated table (51) can be raised and lowered as described above, and when the laminated table (51) is raised and lowered, the sensing member (51)
2) detects the fabric at the top layer of the platform, and even if the platform (51) is lowered one by one for each fabric thickness, the platform (51) is raised to the bottom surface of the conveyor (30) and stacked; Next, the stand (
51) may be lowered to the old position. On the other hand, it has the required fixed size L as the body material, and its l1
The defective fabric (c) with a flawed part (58) is
As shown in Figure 0, it is housed in the housing part (31),
That is, the sensing member (29) detects this defective fabric (c), and the guide plate (4) in the storage section (31)
6) is rotated and tilted towards the suction roller (34) side of the suction conveyor (30) via the drive cylinder (47) etc. At this time, suction on the suction conveyor (30) is stopped, and the conveyor (28) The upper body fabric (c) is collected into the collection box (45) via the suction conveyor (30) and the guide plate (46) in a non-adsorbed state, and the conveyor (30
) will be stopped according to the count of the timer and counter on the same conveyor, and the guide plate (46) will also be returned to its old position, and this recovered defective fabric (c)
The material is later turned for flaws so that the flawed portion (58) is located at the position of the cutting waste (57) in the cut portion, and the material is cut separately.

In addition, in the case of the sleeve fabric (d), like the body fabric (a), it is transported via the conveyor (28) and suction conveyor (30),
They are stacked and accommodated on a stacking table (53) in an alignment accommodating section (33) that is parallel to the alignment accommodating section (32).

In the embodiments described above, as illustrated in FIG. 19, from the long fabric (1) made of the tubular knitted fabric, for example, the body fabric (55) of a shirt, the sleeve fabric (6
1), etc., but as shown in Fig. 41, this involves cutting out the body material (55) for the bottom of the pants and the lint material (61) from the same long material (1).
) can also be applied in the same way. That is, as shown in the first row of the figure, l1+l2+l
3+l2+l1=L A pair of body fabrics (55) (55) are cut along the cutting line (56) from a piece of cut fabric with a required length of L.
When cutting, in the first row shown in the figure without any flaws (58), the method and device of the present invention can similarly cut to the same size and cut, and the cut scraps (57) can also be suctioned. It is recoverable. Therefore, these body materials (55) are number 48
As shown in the figure, it can be accommodated in exactly the same way on the stacking table (51) of the cleft alignment accommodation section (32). This time, the cutting waste (5
7) is difficult to be collected by suction due to its shape, size, etc., as shown in Fig. 42, the suction conveyor (30)
As the suction roller (34) in
7) may be dropped and collected from the suction roller (34) position into a separate collection box (64) as shown in the example (FIG. 48). As shown in the second row of Fig. 41, if there are flaws (58) (58) at the l1 and l1 portions at both left and right ends of the required dimension L, this is a defective piece that can be replaced. The fabric is cut into uncut rectangular fabric pieces of the required fixed size L, collected at random into the storage section (31) shown in Fig. 48, and then passed around to make body fabric (55) ( 55), and as shown in the 8th row of Figure 41, if there is a flaw (58) in the l2 and l2 parts of the figure at the required size L, this can be used as body fabric. cannot be used, so this is a cloth for gosling (61) with a length l shorter than the required size L.
By reusing it as a rectangular piece of fabric, it is necessary to cut it into a length l and then separately cut and collect a plurality of pieces of gossamer (61a), and this fabric for gossamer (61) is The stacking table (53) of the alignment storage section (32) in Fig. 48
As described above, the method and apparatus of the present invention can be applied to various cut fabrics depending on the purpose and use, and of course fabric (1), knitted fabric, woven fabric, etc. It does not matter whether it is a cylindrical object or a single sheet object, and in implementation, the fabric feeding speeds of the active feeding rollers (6) (6) and the cutter roller (8) are the same. , and a conveyor (28
) and the suction conveyor (30) are set higher than those of the rollers (6), (6), and (8), respectively, and the feed speed of the suction conveyor (30) is set to be higher than that of the conveyor (28). It is preferable to make it larger than .

The present invention is as described above, and compared to conventional fabric cutting,
A piece of fabric that can be cut to a desired length by moving a continuous length of fabric in one direction, depending on the presence or absence of knitting, weaving, etc. in the fabric and its position, and cutting by flaw mawashi processing. It automatically sorts out pieces of fabric that are shorter than the required length, but can be repurposed and cut, and instantly cuts fabric pieces that have the required length and can be cut. This is extremely advantageous in that fabric loss can be eliminated and a large number of cut fabric pieces can be produced extremely efficiently by allowing other pieces of fabric to be cut individually through post-processing. 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 movement path, appropriate selection of the fabric pieces, and cutting of each selected fabric. Since the target pieces of dough are processed continuously depending only on the presence or absence of the machine, the work efficiency is extremely high, saving labor and increasing speed. At this time, by directing the flawed parts 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, it is possible to transfer the fabric to the subsequent process. and division of labor is easy.

In addition, in the present invention, as a device, a sensing member (3) for detecting a flaw, a positive feed roller (6), (6), and a sensing member (3) are arranged at a desired length L. The above-mentioned flaws can be detected and removed using only the cutting section using the fabric pressing roller (7) and cutter roller (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 sorting fabric pieces, deciding whether to cut or not, and cutting and separating are performed smoothly, and the active feed roller (6) and cutter roller (8) are also used as a means of measuring dimensions.
It is sufficient to provide a counter on each side, which allows error-free determination of the length of the fabric piece.
It can be designed more compactly than conventional cutting equipment, and is excellent in that it can quickly and efficiently produce cut fabric pieces from long fabrics.
