Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern aligning and spreading device suitable for a pattern cloth whose pattern pattern is easily deformed by a slight external force.

[0002]

2. Description of the Related Art In the manufacture of ready-made garments and the like, after fabrics are rolled up in a laminated state, a sewn part (hereinafter simply referred to as a part) is cut in a layered state by inserting a mold. Based on the placement data of the parts entered in advance in the computer,
There is also a device that automatically cuts on a stretch table. In any case, in the case of patterned fabric, it is necessary to align the upper and lower fabrics when unfolding and stacking the fabrics, and further it is necessary to perform pattern alignment between the parts to be cut. .

As a conventional pattern matching device, Japanese Patent Publication No.
-35306, JP-A-62-276074, JP-A-3-33263, etc. are known. These devices are common in that the stretched and laminated cloth is fixed and held by a puncture needle provided on the lower surface side of the cloth. Furthermore, the device that performs pattern matching while unfolding is
It is known in Japanese Patent No. 5894 and Japanese Utility Model Laid-Open No. 4-46072.

[0004]

As described above, in order to cut the laminated patterned fabrics and to align the patterns of the respective parts, first, the upper and lower fabrics are properly aligned at the time of spreading and laminating, and then It is necessary to correctly match the pattern positions between the parts, but it is difficult to satisfy these at the same time. One of the causes of difficulty in positioning and pattern matching is that there are variations in pattern size and pattern pitch at the time of production even with the same pattern material. The size and pitch of the pattern are different for each material roll wound in a roll shape, and even if the same material roll is used, similar variations are often seen depending on the winding position of the material, and the variation state is not regular.

Another cause is that the stretched fabric is easily locally deformed by a small external force, and when stretched and laminated, the fabric is stretched or shrunk. In particular, in the case of a soft and weak fabric, or a fabric in which a weave is coarsely formed by thin threads, the pattern pattern is likely to be locally deformed. Therefore, even if this type of pattern cloth is spread by the conventional spreading device, the pattern row lines are distorted vertically and horizontally. In the case of a fabric with a strong waist, the distorted portion can be picked up to correct the position, but if such a position correction is performed with a fabric with a weak waist, the picked-up dough portion will be stretched and deformed. Furthermore, the dough on the lower surface side of the picked-up dough shifts at the same time. In this way, since fabrics with a weak waist cannot be accurately spread by the spreading device by vertically spreading sweat, this type of fabric should be used as a fabric for ready-made clothes that are intended for mass production. There was no.

An object of the present invention is to provide a pattern aligning and spreading device that can properly spread and stack even a pattern fabric having a weak waist and easily deformed. Another object of the present invention is to obtain a pattern aligning and spreading device capable of appropriately aligning the stretched cloths with each other and properly aligning the patterns between the parts.

And that the feeding table 2 includes a first carriage 2A that supports the material roll 3 and a second carriage 2B that is adjacent to the material feeding side of the first carriage 2A, and both carriages 2A and 2B. Are adjacent to each other in the same plane.
.47 is provided, and both carriages 2A and 2B are connected by a connecting tool 49 that can be operated to release the connection.

[0009]

[Operation] At the time of the unrolling, the dough delivered from the dough roll 3 is fed by the dough delivery plate 32 of the first carriage 2A and the second carriage 2B.
Extend it on 47 and let it stand. Then, with reference to the light beam L constantly projected on the cloth surface, the pattern row lines of the cloth are aligned vertically and horizontally and accurately positioned. Next, the connection tool 49 is released to move the second carriage 2B to the side away from the first carriage 2A as shown in FIG. 12, and the positioned fabric is applied to the spreading base 1 by its own weight. Drop it. Thereafter, the dough is cut in the width direction on the dough exit plate 32 of the first carriage 2A, the first carriage 2A is moved to the side away from the second carriage 2B, and the dough on the dough discharge board 32 is spread 1 To the side of. After that, the two carriages 2A and 2B are connected by the connecting tool 49, and the above-mentioned retraction operation is repeated. As described above, according to the present invention, the dough is fed onto the dough feeding plates 32 and 47 of both carriages 2A and 2B and made stationary, and the dough is aligned with the light beam L as a reference. Therefore, the feeding table 2 is moved. However, the dough can be positioned more accurately than the case where the dough is unrolled and spread. The two carts 2A and 2B are moved to drop the positioned stationary fabric onto the side of the spreading base 1 by its own weight, so that the tension in the spreading direction that causes distortion when the fabric is laid down is applied to the fabric. It can be excluded from acting.

In the stretch table 1 provided with the elevating frame 10, the pricking needle 8 is placed between the elevating frames 10 and the cloth receiving plate 11 is placed on the upper surface of the elevating frame 10. The dough is stretched and laminated. At this time, the projecting height of the elevating frame 10 is adjusted by the elevating mechanism 17 so that an appropriate amount of the tip of the pricking needle 8 projects onto the upper surface of the cloth receiving plate 11. When the retraction is performed in this state, it is possible to prevent the puncture needle 8 from interfering with the retraction and fix the deflated material by piercing the puncture needle 8. The protruding amount of the puncture needle 8 decreases as the fabrics are piled up, but the lifting frame 1

The amount of protrusion from the dough surface can be maintained at an appropriate amount.

[0011]

According to the present invention, the feeding table 2 is composed of the first truck 2A and the second truck 2B, and the dough is fed from the dough roll 3 onto the dough feeding plates 32 and 47 of both the trucks 2A and 2B and extended. The fabric is accurately positioned with the light beam L as a reference in the stationary state. Furthermore, both trolleys 2
By moving A and 2B, the positioned fabrics can be dropped and stacked on the side of the stretch table 1 in that state. Therefore, according to the spreading device of the present invention, even if the patterned fabric is flexible and has a low stiffness and is easily deformed by a slight external force, it can be properly stretched and laminated with the upper and lower fabrics aligned. Therefore, it is possible to improve the added value of ready-made clothes by adopting the cloth which has been difficult to apply to ready-made clothes in the past.

According to the pattern aligning and spreading device of the present invention, the cloth spreading plate is received by the cloth receiving plate 11, and the elevating frame 10 is operated to descend to spread the cloth receiving plate 11 appropriately. Of course, it is possible to efficiently spread the work of the patterned fabric without being disturbed by the puncture needle 8, and it is possible to fix the laminated fabric with the puncture needle 8 until the cutting is completed. Further, since the pricking needle 8 is fixedly fixed on the upper surface of the stretch table 1, the fixed position can be freely changed according to the size and layout of the parts. Since the pattern 5 can be laid out by using the light beam L after spreading and pattern matching between the parts can be performed, a series of pattern matching operations from spreading and stacking of fabrics to pattern insertion can be performed on the spreading table 1. It is also advantageous in that it can be performed accurately and consistently, and as a whole, the efficiency of the cloth placement operation can be improved, and the cost required for manufacturing clothes can be reduced accordingly.

1 to 13 show an embodiment of a pattern aligning method and a pattern aligning and spreading device according to the present invention. In FIG.
Reference numeral 1 is an extension table, 2 is a feeding table that reciprocates on the extension table 1, 3 is a material roll supported on the feeding table 2, 4
Is an optical marker that constantly projects a position reference line toward the stretch table 1. Using these devices, a series of dough-fixing operations from spreading and stacking of dough to molding are performed. The dough placing operation includes a preparation step, a needle placing step, a plate placing step, a spreading step, a needle exposure amount adjusting step, and a mold placing step. In order to make the whole work easier to understand, these steps will be described first.

In the preparation step, the cloth to be spread is spread on the spreading stand 1
After the paper is spread upward, the pattern paper 5 is actually arranged on the cloth for spreading while referring to the mold drawing shown in FIG. 4, and the position of the projection beam of the optical marker 4 is determined. Basically, the position of the optical marker 4 is determined so that the light beam L is projected on the vertical reference line 5a and the horizontal reference line 5b provided on each pattern 5. However, since it is basically necessary to match the patterns of the respective parts and there is a relation of the scale, the position of the light beam L is set around the two main reference lines 5a and 5b.

The mold drawing shown in FIG. 4 shows the case of a women's jacket. In this case, four light beams L are projected in parallel with the feeding direction, and in the width direction orthogonal to this. Two light beams L were projected on each divided block B. After the beam projection position is determined, the pattern 5 is removed,
The unfolded dough is rewound on the dough roll 3.

In the needle placement step shown in FIG. 3, the cloth base 7 is spread on the spreading base 1 having a thin steel plate fixed on the surface and fixed with an adhesive tape or the like, and the puncture needle 8 is fixedly fixed on the surface. The fabric base 7 is provided to take out the laminated fabric after the series of operations is taken out of the spreading table 1, and a web material or a sheet material such as paper, a plastic film, or a thin plate that does not interfere with cutting is applied. it can.

FIG. 5 shows the puncture needle 8. The puncture needle 8 has a needle 8b standing on a seat plate 8a made of a transparent plastic plate.
It is formed by attaching a rubber magnet 8c to the lower surface of a,
Depending on the size of the parts, the number of standing needles 8b varies from about 1 to about 4. The puncture needle 8 is set in correspondence with the part position determined in the preparatory step, and one puncture needle 8 is positioned at the intersection of the light beams L intersecting vertically and horizontally as much as possible. The fixed puncture needle 8 is immovably fixed on the stretch table 1 by the magnetic attraction of the rubber magnet 8c.

In the plate placing step, the elevating frame 1 provided on the spreading table 1
0 is raised on the table, and the cloth support plate 11 is placed on the upper part thereof. As will be described later in detail, the elevating frame 10 is provided in parallel with the widthwise ends of the reciprocating table 1 and at three central portions in the width direction, and between the elevating frame 10 at the center and the elevating frame 10 at the end. The dough receiving plate 11 is placed on. As shown in FIG. 6, the cloth receiving plate 1
1 is formed by fixing metal plates 11b for reinforcement to two lower surfaces of a transparent plastic receiving plate 11a. In order to enable the cloth receiving plate 11 to be placed on the elevating frame 10 at the center from both sides. The one metal plate 11b is displaced inward from the side edge of the receiving plate 11a by the width dimension thereof. As shown in FIG. 3, the cloth receiving plate 11 is arranged so as not to interfere with the needle 8.
Since the distance between adjacent needles changes depending on the arrangement of the puncture needles 8, several types of cloth receiving plates 11 having different width dimensions are prepared.

After placing all the fabric receiving plates 11, it is confirmed that the elevating frame 10 can be moved up and down so that the pricking needle 8 and the fabric receiving plate 11 can be raised and lowered relative to each other without any trouble. Position the elevating frame 10 so that it projects by a few millimeters. In this state, spread the spread paper on the cloth backing plate 11 and insert the needle 8.
Stab it in. This backing sheet serves to facilitate the removal of the fabric support plate 11.

The details of the spreading process will be described later, so only the outline thereof will be described. In this step, the dough is unrolled from the dough roll 3 and spread on the unrolling table 2, and the dough is positioned based on the light beam L projected on the dough surface. Next, the second carriage 2B of the feeding table 2 is moved to drop the positioned cloth on the cloth receiving plate 11, and the cloth is held by the long presser bar 55 to pierce the needle 8. 1st trolley 2
After cutting the cloth on A, the first carriage 2A is moved to drop the remaining cloth on the cloth receiving plate 11, and similarly fixed by the needle 8. After that, the dough is laminated by repeating the spreading, positioning, dropping cutting, etc. of the dough. The material is cut for each of the divided blocks B in order to newly position each of the divided blocks B and avoid accumulation of errors.

In the needle exposure amount adjustment step, the above-mentioned retraction step is
After every several times, the elevating frame 10 is lowered to adjust the protrusion amount of the puncture needle 8. When the elevating frame 10 is lowered, the laminated fabric supported via the fabric receiving plate 11 sinks.
Therefore, when the surface of the cloth is lightly pressed, the pricking needle 8 projects a proper amount from the cloth on the uppermost surface. The appropriate amount of protrusion of the needle tip is about 3 mm for thin fabrics.

In the pattern inserting step, the pattern paper 5 is arranged on the uppermost fabric surface while being positioned by the light beam L of the optical marker 4, and the pattern paper 5 is fixed to the laminated fabric with the holding needle 14 inserted from the surface side. wear. At this time, the pattern paper 5 uses the light beam L and is accurately positioned vertically and horizontally using the pattern line of the stretched cloth as an index, and the pattern matching between the parts is performed by the pattern matching written on the pattern paper 5. The points are checked visually by the operator. As shown in FIG. 5, the holding needle 14 is formed by fixing 2 to 4 needles to a seat plate having a length of several centimeters.

Next, after the elevating frame 10 is lowered below the surface of the stretch table 1, the cloth receiving plate 11 is pulled out. As a result, rough cutting can be performed by the vertical blade cutter on the reciprocating table 1. Of course, for each cutting block B, the entire laminated fabric together with the fabric base 7 can be taken out from the spreading table 1 and transferred to the cutting machine. The cutting machine cuts the laminated material along the pattern paper 5. Then, the holding needle 14 and the puncture needle 8 are removed. The seat plate 8a of the puncture needle 8 may be cut during cutting. To protect the cutting blade in such cases,
The magnet fixed to the seat plate 8a is formed of a soft rubber magnet 8c.

Next, the structure of the pattern aligning and spreading device will be described.
In FIG. 2 and FIG. 7, the handle aligning and spreading device comprises a spreading base 1 formed by arranging a plurality of unit bases 1A in a straight line and a guide rail 16 arranged at both ends in the width direction of the spreading base 1. It is configured to include a reciprocating feeding table 2, an optical marker 4 for projecting a positioning light beam L onto the retraction table 1, a puncture needle 8 fixed on the retraction table 1, and the like.

Each unit base 1A is provided with an elevating frame 10 and an elevating mechanism 17 for operating the elevating frame 10. As shown in FIG. 7, the elevating frames 10 are provided at a total of three places, that is, two places inside the guide rails 16 near both ends in the width direction of the stretch table 1 and a center portion in the width direction of the stretch table 1, respectively. An elevating groove 18 is opened corresponding to the position where the elevating frame 10 is arranged.

In FIG. 8, the lifting mechanism 17 is a unit base 1A.
A vertical screw shaft 19 rotatably supported at the four corners of the female screw unit 2 and a female screw unit 2 that is vertically moved along the screw shaft 19.
0, an interlocking mechanism that simultaneously drives four screw shafts 19 in the same direction, and a pair of frame holders 21 fixed to a pair of female screw units 20 that are adjacent in the width direction. The lower end sides of the three lifting frames 10 are fixed to a pair of frame holders 21.

The interlocking mechanism includes an operating shaft 22 axially supported in parallel with the elevating frames 10 at both ends in the width direction, a chain mechanism 23 provided between the pair of operating shafts 22, and each operating shaft 22 and the screw shaft 19. And a handle 25 fixed to one end of the operating shaft 22, and the like. By rotating the handle 25, the elevating frame 10 is moved between a raised position where the upper end of the elevating table 1 projects from the upper surface and a lower position where the upper end of the elevating frame 10 retracts below the upper surface of the elongating table 1. You can move up and down with. By connecting the operation shafts 22 between the adjacent unit bases 1A, all the elevating frames 10 can be operated up and down at the same time.

In FIGS. 1 and 9, the feeding table 2 is
It consists of a first carriage 2A and a second carriage 2B. 1st trolley 2A
Is an undercarriage 28 with freely rotatable wheels 27 arranged at the four corners of the lower surface.
And a pair of roll receiving frames 29 provided on the chassis 28, a feed roller 30 circumscribing the fabric roll 3 to feed out the fabric, and a transmission mechanism for transmitting the rotational force of the wheels 27 to the feed roller 30. To do.

The chassis 28 includes a pair of side frames 31 and a side frame 31.
Horizontal dough discharge plate 32 and side frame 31 arranged between
It is composed of a roll stand 33 standing upright. This roll stand 3
The feed roller 30 is disposed on one side of the sheet No. 3 and is rotatably supported via a bearing. The roll receiving frame 29 is arranged so as to incline downward toward the feed roller 30, and the inclined lower end thereof is set to the shaft 3
The tilting upper end is supported by the adjusting shaft 35. The nut 3 for engaging the adjusting shaft 35 with this
By operating up and down with 6, the inclination amount of the roll receiving frame 29 can be changed and the contact pressure between the material roll 3 and the feed roller 30 can be adjusted.

It should be noted here that the dough-feeding plate 32 is made to protrude largely from the lower part of the feed roller 30 in the dough-feeding direction so that the dough-positioning can be aligned on the upper surface thereof. In order to reduce the frictional resistance with the plate 32 and at the same time prevent the generation of static electricity,
The dough dispensing plate 32 is formed of a transparent glass plate.
The fact that the surface of the already stretched cloth can be visually recognized through the transparent cloth discharge plate 32 is also useful in giving the operator a sense of security. A guide plate 37 is provided adjacent to the protruding end of the material delivery plate 32 for guiding the material obliquely downward.

A transmission mechanism is provided between the feed roller 30 and the wheel 27 in order to feed the dough without touching the dough roll 3. The transmission mechanism has an intermediate shaft 38 arranged in the vicinity of the wheel 27 and parallel to the axle, transmits the power of the wheel 27 to the intermediate shaft 38 via a pair of gears 39 and 40, and further transmits the power of the intermediate shaft 38 to the timing belt mechanism. It is transmitted to the feed roller 30 via 41. As shown in FIG. 10, the intermediate shaft 3
8 is supported by a bracket 42 so as to be movable left and right,
By operating the U-shaped operation frame 43, which sandwiches the gear 40 and the timing pulley, with the switching lever 44 left and right, it is possible to switch between the state in which the gear 40 meshes with the gear 39 on the wheel 27 side and the state in which the gear 40 is disengaged. This is because the feed roller 30 is rotationally driven only when the dough is fed.

The second trolley 2B has a pair of side frames 46 and a transparent glass plate material feeding plate 47 arranged between the side frames 46, like the above-mentioned chassis 28. It is supported by freely rotatable wheels 48. The width dimension of the material delivery plate 47 along the moving direction of the carriage is set smaller than the width dimension of the material delivery plate 32 of the first carriage 2A. This second trolley 2B
To move together with the first trolley 2A and separate from the first trolley 2A as required, so as to separate the side frames 31 of the two trolleys 2A and 2B.
-Connector 49 is provided between 47.

In FIG. 11, the connector 49 is the second carriage 2
A connecting arm 50 rotatably attached to the side frame 46 of B, and
It consists of a retaining groove 51 fixed to the side frame 31 of the trolley 2A,
When the connecting arm 50 is operated and the shaft 52 formed at the tip thereof is locked in the locking groove 51, the two carriages 2A and 2B are integrally connected and can move together.

The optical marker 4 is composed of a laser oscillator for projecting visible light, and is attached to a guide frame 54 provided above the extension table 1 as shown in FIG. 2, so that the light beam L is linearly formed on the table. To project. One optical marker 4 projects one light beam L, but if the longitudinal dimension of the reciprocating table 1 exceeds the irradiation range of the optical marker 4, a pair of optical markers 4 arranged above both ends of the reciprocating table 1 is provided. The continuous light beam L is formed by the light marker 4 of FIG.

As shown in FIG. 12, the presser bar 55 is a frame 56 made of wood or aluminum and has foam rubber 57 attached to one or both sides of the frame 56. The thickness of the rubber 57 is set large.

Next, a method of using the feeding table 2 in the spreading process will be described. Spreading is started by moving the feeding table 2 along the guide rails 16 and extending the cloth wound on the cloth roll 3 onto the upper surfaces of the cloth discharging plates 32 and 47 of both carriages 2A and 2B. After spreading an appropriate amount of cloth, the light beam L of the optical marker 4 is used to position the movement start position of the feeding table 2 and at this position, the cloth feeding plate 32.4
7. Manually position the fabric that has been spread on top. When the fabric is simply extended, the pattern row lines are distorted vertically and horizontally. Therefore, the entire fabric is manipulated or the position of the distorted part is corrected so that the vertical and horizontal pattern row lines become the vertical and horizontal lines of the light beam L. Match them.

Next, the presser bar 55 is placed on the cloth feeding plate 32 of the first carriage 2A, and the cloth is fixed by its weight. By removing the connecting arm 50 from the hook metal fitting 51 so that the two carriages 2A and 2B can be separated and the first carriage 2A is fixed, the second carriage 2B is moved to a side away from the carriage 2A,
As shown in FIG. 12, the dough on the dough delivery plate 47 is dropped to the dough receiving plate 11 side. That is, without touching the positioned fabric, the fabric is dropped by its own weight and laid down. At this time, since the movement start position of the second carriage 2B is positioned in advance, the patterns at the material edges of the material receiving plate 11 are uniform. After that, the dough is cut with scissors along the presser bar 55, the cut end is aligned and positioned on the dough discharge plate 32, the presser bar 55 is removed, and the dough bar 55 is placed on the surface of the laminated dough to insert the dough needle 8 Stab it in. In this state, the first carriage 2A is moved to the side away from the second carriage 2B, and the remaining cloth portion is dropped onto the cloth receiving plate 11 side. As a result, the spreading and stacking on the divided blocks B located at the ends is completed.

The fabric can be stretched and laminated on the second and subsequent division blocks B by repeating the above procedure, but the difference is that the separation movement start position of the second carriage 2B matches the corresponding division block B. There is. When the second trolley 2B is connected to the first trolley 2A with a connector 49 and the material on the material delivery plate 32 is extended onto the material delivery plate 47 on the second vehicle 2B side, the cut end is pressed down. 2nd trolley 2 by pressing with 55
Send to B side and operate. This is to avoid local deformation of the dough.

The width dimension of the dough roll 3 varies from roll to roll and is not constant. Even with one roll, there are variations. In such a case, it becomes difficult to match the pattern row lines in the reciprocating direction between the fabrics stacked on top of each other. This is because even if the pattern row lines are aligned near one end of the cloth in the width direction, the pattern row lines are displaced toward the other end. In order to eliminate the positional defect of the laminated fabric due to the variation of the roll width of this kind, it is preferable to perform the spreading lamination from the fabric roll 3 having a small roll width. Then, when the roll width becomes wide and a plurality of pattern tag lines in the unfolding direction do not match, the strip 58 is arranged on the upper surface of the stretched cloth layer T as shown in FIG. By detouring the fabric along the line 58, it is possible to absorb the deviation of the pattern line. However, since it is not possible to place the parts on the cloth surface that bypasses the strip 58, it is necessary to avoid this bypass and lay out the pattern paper 5. In other words, after confirming the variation of the roll width in advance, a detour area substantially parallel to the extending direction is secured in advance, and when the material width exceeds a predetermined value and becomes large, the strip material 58 is placed in the detour area. Place and spread.

FIG. 14 shows a modification of the first carriage 2A. In this modification, a small cutting device 60 is arranged in the vicinity of the upper surface of the feed roller 30, and one end (or both ends) in the width direction of the cloth before spreading is cut by the small cutting device 60, and cut into a tape shape. The dough is wound on a reel 61 provided near the dough roll 3. In this way, the tape-like material is cut prior to the spreading, when the material is cut into the dividing blocks B, it is impossible to form a long part exceeding the length of the dividing block B with the co-fabric. To deal with. The tape-shaped material is used, for example, to form parts for waist belts.

The feeding table 2 of the present invention is preferably used together with the reciprocating table 1 having the elevating frame 10, but it is not always necessary. Instead of raising and lowering the lifting frame 10,
The frame 10 is fixed, and the base plate for receiving the puncture needle 8 and the guide rail 16 are moved up and down, so that the same spreading as in the above embodiment can be performed. The elevating frame 10 can be moved up and down by an elevating mechanism 17 using a motor or a fluid pressure cylinder as a power source, and is not necessarily a continuous frame body. In order to position the separation movement start position of the second carriage 2B for each division block B, a position sensor may be provided on the retraction table 1 and the stop position of the second carriage 2B may be specified by this position sensor. it can. It is desirable that the position sensor be able to change the mounting position along the extending direction.
