Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a fabric defect position confirmation device for checking whether a defect appears in the fabric of the fabric fed out from a spreading machine and whether the defect occurs in parts cut by reduction marker paper.

[Conventional technology]

Conventionally, as shown in, for example, Japanese Patent Application Laid-Open No. 123472/1983, a cloth fabric supported by a cloth spreading machine main body which reciprocates in the spreading direction on a cloth spreading table 2 is fed out, There has been a fabric spreading machine that performs fabric spreading by appropriately cutting the fabric fed out in the width direction by a cutting device provided on the main body, thereby obtaining a laminate in which fabrics are laminated in a plurality of upper and lower layers. The laminate obtained in the above manner is made of marker paper with fabric cutting pads cut in several places along the entire length of the marker paper so that the edges of all the parts are almost aligned in the width direction. The fabric cutting pattern written on the marker paper is then cut into multiple types of parts using a cutting device, and the fabric of each part is then sewn into products such as clothing. In a case like O, the cloth fabric has various defects called cloth parts, such as missing wefts, uneven dyeing, stains due to adhesion of oil, etc., and if these defects are included in products such as clothing. This will result in a loss of product value. Therefore, before spreading the fabric, we inspected the location and type of defects in the fabric using a fabric inspection machine, and pasted a sticker on the side edge of the fabric, called the edge of the fabric, and attached it to the main body of the fabric spreading machine. A sensor detects a seal during spreading and automatically stops the spreading machine, and the first unrolled fabric is cut in the width direction to remove defective parts.

[Problem that the invention is intended to solve]

As mentioned above, conventionally, when a defect appears in the fabric of the fabric during spreading, the fabric is cut in the width direction to remove the defective part (7). In addition, since it is impossible to know at a glance which part of which product contains the defect, as mentioned above, the edges of all parts are approximately By making stamps on marker paper so that they line up, and using these positions as fabric joining positions when spreading the fabric, when a defect appears, the fabric can be cut in the width direction to remove the defective part. This is because the fabric is returned to the splicing position and the fabric is spread again. However, this has the problem that a lot of fabric is wasted and the cost of the product increases. Also, if the fabric is cut after spreading, In order to find out which part has the defect or whether the defect is located between parts, it is a good idea to check the position of the defect in the fabric during spreading by looking at a marker paper with the actual size fabric cutting pattern written on it. However, although this puts a lot of burden on the worker, it is easy to make mistakes.Furthermore, the data from when the marker paper was created using Konopyuku17 is used to determine the location of the defect. A device has been proposed that can be attached to a spreading machine to check the relationship between defects in the fabric and the position of the marker paper, but this device (costly and expensive as it is quite large) has been proposed. Therefore, there is a problem that it is difficult to put it into practical use.This invention is an attempt to solve the above-mentioned problems. Workers can easily check which part the defect is in or whether it is between parts during the spreading process, and the defect can be dealt with accurately by cutting, with a relatively simple structure and low cost. It is an object of the present invention to provide a fabric defect position confirmation device for a fabric spreading machine that is inexpensive and suitable for practical use.

[Means to solve the problem]

This invention provides a cutting device for cutting in the width direction the fabric rolled out from the fabric supported by the main body of the fabric spreading machine which reciprocates in the spreading direction on the fabric spreading table 2. A fabric defect position confirmation device for a fabric spreading machine equipped with
L is fixed in a suitable position on the spreading machine, and a mounting plate of reduced marker paper on which the fabric cutting pattern is written at a predetermined scale is fixed on one side of the main body of the spreading machine, and it is removably attached to this mounting plate. A reduction scale 11-1, which straddles a reduced marker paper perpendicular to the direction of spread and has the same scale ratio as the marker paper, is supported on the mounting plate so as to be able to reciprocate in the direction of spread. The reduction scale is connected to an interlocking mechanism that reciprocates in the same direction as the spreader main body by a distance corresponding to the scale ratio of the reduction marker paper and the reduction scale with respect to the traveling distance of the main body.

[For production]

In the fabric defect confirmation device according to the invention of Party B, when spreading is carried out by removably attaching a reduction marker paper to a mounting plate fixed to one side of the main body of the spreading machine, the device interlocks with the movement of the main body in the spreading direction. Since the reduction scale is moved by the mechanism in accordance with the scale ratio of the reduction marker paper, the actual size scale is fixed in the spreading machine, so that the part pattern written on the reduction scale and the part pattern drawn on the reduction scale are fed out during spreading. The relative position of defects in the fabric can be easily checked in both the stretching and width directions of the fabric, allowing the operator to see at a glance which part the defect is in, and whether it is between parts and not inside the part. You can see it. Therefore, it is possible to accurately and quickly judge whether to cut the fabric in the radius direction and remove the defective parts, or to continue spreading the fabric and, if necessary, to sort out and remove defective bars in subsequent processes. In addition to reducing fabric loss, the structure is simple as there are no large and expensive parts.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In Figures 1 and 2, 1 is the top plate 1) on the base leg 1a.
The spreader main body 2 is supported movably in the spreading (longitudinal) direction on the top plate of the spreading material 81 (B). A cutting device 3 is fixed to one end of the main body 2 in the cloth spreading direction (back and forth), and the cutting device 3 has a cloth 4a of the cloth 4.
A support member 6 for removably supporting the 33-piece fabric 4 is provided on the main body 2, and the support member 6 and the cutting device 3 are connected to each other in the width direction. An actual size scale 7 is arranged between them. The actual size scale 7 is fixed to the housing 3a of the cutting bag M3, extends in the width direction of the fabric 4a of the fabric 4 at right angles to the stretching direction, and straddles the fabric 4a in close proximity to it. An upper edge of a mounting plate 8 is fixed to one side of the main body 2, and the mounting plate 8 has a mounting surface 8a projecting diagonally downward outside the main body 2.
A reduced marker paper 9 with a scale of 1/10 is removably attached to the sheet with its long sides parallel to the spreading direction. The reduced marker paper 9 is straddled by the reduced marker paper 9 in the rolling direction and at the IF angle, and the reduced marker paper 9 is formed on a scale with a scale of 1/10, as shown in FIG. , the slider fixed to the reduction scale 10 via the connecting fitting 1]
2 is engaged with the slide rail 13 provided at the lower end 8b bent inside the mounting plate 8, so that the reduction scale
0 is supported by the mounting plate 8 so as to be able to reciprocate in the direction of rolling. lth mechanism 14. The interlocking mechanism 14 has a timing belt 15 which is stretched between the front and rear legs 1a and horizontally extends slightly longer than the length of the tape in the direction of spread.A timing gear 16 is engaged with the timing belt 15 from below. A guide roller 17 arranged in close contact with the timing belt 15 from above,
The timing gear 16 and guide roller 17 are mounted on the mounting plate 8.
It is pivotally supported by a bearing plate 18 fixed to. A small gear 19 provided integrally with the timing gear 6 is interlocked with the large gears 20 and 11, and an endless timing belt 2 is attached to the driving timing gear 2 provided integrally with the large gear 20.
It is engaged with 2. The timing gears 1 and 22 are hooked onto the drive timing gear 21 and the tenon pulley 23, are supported by the mounting plate 8 via these, extend horizontally in the direction of rolling, and further have the connecting fitting 11 fixed thereto. . And timing bell)・15 is 5 +nm
The timing gear 16 has a large number of teeth with a pitch of 5 m.
The number of teeth of the small gear 19 is 0 teeth, the number of teeth of the large gear 20 is 00 teeth, and the drive timing gear 2 is 5.
A Kuiminogbe sword with 20 teeth each. 1 and 22 also have a large number of teeth with a pitch of 5 mm, and as a result of the self-propulsion of the main body 2 in the spreading direction, the reduced scale 10 is moved in the same direction at a scale rate of 1/]0. Configured to move. In addition, in FIG. 2, 24 is a running wheel provided on the main body of the spreading machine, and 25 is a top plate of the spreading table 1.]
bJ: is a running guide provided at the machine to guide the running wheels 24 in the spreading direction; in FIG. It is a seal sensing processor. Next, the operation of the embodiment configured as above will be explained. While the spreading machine main body 2 is moved in the spreading direction on the top plate 1b of the spreading table 1 by an electric motor (not shown) provided on the main body 2, the fabric 4a is transferred from the fabric 4 supported by the support member 6 to the top plate. 1
b, the fabric 4a is cut in the width direction by the cutter 5 at the forward end of the main body 2, the main body 2 is moved back without feeding out the fabric 4a, and the fabric 4a is repeated while moving the main body 2 forward again. The process of obtaining a laminate in which fabrics 4a are laminated in multiple layers on the spreading table 1 is similar to the spreading operation performed by a conventional spreading machine of this type. In this embodiment, as the spreader main body 2 travels, a mounting plate 8 fixed to one side of the main body 2, a bearing plate 18 fixed to the mounting plate 8, and a timing shaft supported by the bearing plate 18 are used. Since the gear 16 and the guide roller 17 also move in the same direction, the timing gear 16 rotates because it is meshed with the hinge jL1.15 stretched between the front and rear legs 1b. The rotation of the timing gear 16 is transmitted to the large gear 20 via a small gear 19 provided integrally with the timing gear 16, and a driving timing gear 21 provided integrally with the large gear 20 rotates, and a timing belt meshes with this gear 21. 22 moves in the running direction of the main body. Therefore, the reduction gear 10 also moves in the running direction of the main body 1 via the connecting fitting 11 fixed to the timing belt 22. In this case, timing gear 16, small gear 1
9. Since the large gear 20 and the driving timing gear 21 are set to the above gear ratio, the travel distance of the reduction scale 10 is 1710 times the travel distance of the main body 2, and the fabric 4a of the reduction marker paper 9 pasted on the mounting plate 8 Scale rate 1/10 for
This will correspond to Then, when the fabric 4a is fed out to the position where the defect 4b is located, the sensor 27 detects C, n, 26, and the fabric spreading machine stops. therefore,
If the fabric 4a has a defect 4b, the operator can see the position of the reduced marker paper 9 along the direction of spread due to the movement of the reduction scale 10. The position can be immediately read by the reduced marker paper 9, and the position of the defect 4b in the width direction of the fabric 48 can also be read by the scale of the actual size scale 7 provided on the spreading machine. and the reduced marker paper 9 can be read immediately. Since the reduced marker paper 9 has a scale of 1/10, unlike looking at the actual size marker paper, the operator can see at a glance which part the defect 4) is in, or whether it is between parts. Recognize. Therefore, it is possible to accurately and quickly determine whether to cut the fabric 4a in the width direction to remove the defect 4b or to continue spreading the fabric. Additionally, if necessary, the position and part number of the layer of fabric 4a with the defect 4b can be recorded by the operator's operation.
In this case, use defective parts after cutting (make sure there are no defects).Furthermore, write down the spreading conditions etc. on the reduced marker paper 9, and use this marker paper 9 to check the spreading length. In addition, in this invention, the reduction marker paper is created by determining the placement of the parts using a combination paper, and then drawing the pattern of each part necessary for cutting work using a plotter or the like in actual size. Using a known technique for creating full-size marker paper, you can easily create a drawing by using blocks at the required scale (1.710 in the above example) based on the same data as the full-size marker paper. In addition, in this invention, if the timing gear 16 of the above embodiment has 30 teeth, it will be 1715, and if it has 40 teeth, it will have 172.
It is possible to move the reduction scale of the scale of 0, and the scale of each part (or the numerical value of the example) can be changed by using the scale of the corresponding scale and size reduction scale. However, instead of the timing gear 16, a roller formed with an outer diameter with a circumferential length that matches the scale ratio is rotatably pressed onto the top plate of the spreading table (7) to obtain the driving force of the reduced scale. Furthermore, instead of the interlocking mechanism using gears in the above embodiment, the reduction scale may be moved by an interlocking mechanism using a bevel gear and a screw shaft, or a spreading machine may be used as shown in FIG. Encoder 2
8 by the roller 31, controlled by the controller 29 to match the scale ratio, and driven by the electric motor 30 to drive the drive gear 32 to move the reduced scale. In the above example, in the case of one-way spreading in which the fabric is fed out of the fabric only when the spreading machine advances, the spreading machine may be stopped. As mentioned above, this invention is effective when the spreading machine moves forward:
It can also be applied to the case of bidirectional stretching, in which the fabric is fed out at the time of retraction and then folded back and stacked at both ends. Effects of the Invention As explained above, the fabric defect position confirmation device of the fabric spreading machine according to the present invention allows the fabric to be fed out from the fabric spreading machine to be moved from the actual size lie 1 that straddles the fabric at right angles to the fabric spreading direction to the fabric spreading machine. A mounting plate for reduced marker paper is fixed on one side of the spreading machine body at a specified scale. A reduced scale that extends at right angles to the spreading direction and has the same scale as the marker paper is supported on the mounting plate so as to be able to reciprocate in the spreading direction, and the reduced scale is moved by the movement of the spreading machine main body. Since the reduction scale is connected to an interlocking mechanism that reciprocates in the same direction as the spreader main body at a distance corresponding to the reduction ratio of the reduction marker paper and the reduction scale, the following effects can be obtained. When the paper is spread with a reduced marker paper attached to the paper, the reduced scale moves in accordance with the scale ratio of the reduced marker paper as the spreading machine moves in the spreading direction, and the actual size scale is fixed on the spreading machine. By doing so, you can easily check the relative position between the part pattern written on the reduced scale and the defect in the unrolled fabric in the M direction of the fabric's rolling direction and width direction, and identify which part the defect is in. The worker can check at a glance whether the defect will fit between the parts or not between the parts.Therefore, the fabric is cut in the width direction to remove the defective part.
It is possible to accurately and quickly decide whether to continue spreading the fabric and select and remove defective parts in the subsequent process if necessary, which further reduces fabric waste and reduces the number of expensive parts that require repeated work. The structure is simple and the device can be provided at low cost.
