Description

[Technical Field]

[0001] The present invention relates to a device for dispensing a shrunken cloth body, a method for dispensing a shrunken cloth body, and a program for dispensing a shrunken cloth body. [Background technology]

[0002] Hotels, inns, and other lodging facilities use linen products of various sizes, such as sheets, towels, and pillowcases. After washing, linen products are dried using a heat press or roll ironer and reused.

[0003] Repeatedly used linen products come in a variety of sizes. To avoid rising accommodation fees, semi-automated cleaning is performed using the process described above. However, in such semi-automated cleaning, it is necessary to automatically distinguish the size of the linen products.

[0004] For example, Patent Document 1 discloses a means for checking the length of clothes based on the time it takes for the clothes to pass through a sensor and the conveying speed.

[0005] Patent Document 2 discloses a device that has an item detection sensor and a width detection sensor for folded sheets, and that sorts items based on the detection result of the width detection sensor. In Figure 1 of Patent Document 2, an item detection sensor is provided downstream of a sensor for detecting different widths, and the item is detected by the item detection sensor after it passes the width detection sensor. Also, in Figure 2 of Patent Document 2, an item width detection sensor is provided downstream of the width detection sensor. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-51428 [Patent Document 2] Utility Model Registration No. 2507047 Summary of the Invention [Problem to be solved by the invention]

[0007] Linen products, such as fabrics, gradually shrink as they are repeatedly washed and dried by heat pressing. For example, when a large-sized fabric, such as a sheet, is conveyed in a roll ironer under high temperature and pressure while being dried, it is conveyed while being subjected to tension in the conveying direction. This causes tensile stress in the conveying direction, causing the sheet to shrink in length in the direction perpendicular to the conveying direction (hereinafter referred to as the "orthogonal direction").

[0008] However, in the method described in Patent Document 1, a sensor is provided at the center of the fabric body to determine the dimensions of sheets, etc. However, even if the sensor is located at the center of the fabric body, it cannot sense shrinkage of the fabric body in the orthogonal direction.

[0009] Furthermore, as mentioned above, in Patent Document 2, an item width detection sensor is disposed downstream of the width detection sensor. For example, when this device is used to transport a fabric object with folded corners, the width of the fabric object varies depending on the detection time, and there is a risk of the width of the fabric object being detected incorrectly.

[0010] Furthermore, the device described in Patent Document 2 is intended to detect the size of a fabric body folded in half or in thirds. However, when using this device to detect a fabric body such as a sheet before folding, problems arise in view of the actual state of the fabric body. As described above, the sheet before folding is conveyed while tension is applied in the conveying direction under high temperature and pressure. For this reason, fabric bodies that are shrunk in the orthogonal direction and even fabric bodies with slightly curved edges in the conveying direction are mixed in. Furthermore, as described above, fabric bodies with bent corners during conveyance are also mixed in.

[0011] Therefore, when the device disclosed in Patent Document 2 is used, the width in the orthogonal direction is not determined, and there is a concern that a fabric body that should be removed from the conveying path may be detected as a product. Conversely, there is a concern that the product may be mistakenly identified as a defective product and removed from the conveying path.

[0012] Furthermore, in fabric bodies such as rectangular sheets, stitching is performed along the side edges to reduce shrinkage. These stitching sections are sometimes transported with the stitching oriented perpendicular to the transport direction. However, repeated drying using a roll ironer causes shrinkage in the middle of the fabric body. Therefore, if the middle of the fabric body shrinks significantly, it can be difficult to make a bed, and it is therefore necessary to prevent such sheets from being shipped. Thus, there is a need for a device that prevents fabric bodies with reduced product value from being shipped as products.

[0013] The object of the present invention is to provide a shrunken fabric body discharging device, a shrunken fabric body discharging method, and a shrunken fabric body discharging program that can discharge, from the conveying path of fabric bodies that have shrunk significantly among fabric bodies being transported on a belt conveyor. [Means for solving the problem]

[0014] In view of the above-mentioned current state of conveyance, the inventors have realized that in order to solve the above-mentioned problems, it is necessary to deviate from the conventional technique of solely determining the standardized size of a fabric body, and have noticed that a means for more accurately detecting the degree of shrinkage of a fabric body is necessary.

[0015] Specifically, the technology focused on the need to avoid misjudging the size of a fabric body when, for example, a corner is bent. Furthermore, as mentioned above, when tension is continuously applied to a fabric body in the conveyance direction, the middle portion of the fabric body shrinks more than the edges in the conveyance direction. This is because linen products, such as sheets, typically have double stitching at the edges, making them less susceptible to shrinkage than the middle portion. Furthermore, because fabric bodies gradually shrink more from the edges toward the middle, their side edges can become curved. Therefore, simply detecting only the edges of a fabric body with a sensor, as in conventional technology, is not enough to accurately determine the current state of the conveyed fabric body and distinguish between a good and a defective product. Therefore, the technology focused on the need to estimate the degree of shrinkage even when the length perpendicular to the conveyance direction is not constant.

[0016] In other words, even if a fabric body has folded corners or curved side edges due to shrinkage in the middle of the fabric body, it should be shipped as a product as long as the curve is slight. Therefore, it is necessary to more accurately determine whether a fabric body should be shipped as a product.

[0017] Here, it is believed that the folding of the corners occurs accidentally when the fabric is moved between conveying devices during conveyance. Furthermore, the degree of shrinkage of the fabric body varies depending on the number of times the fabric body is used. If the middle part of the fabric body is shrunk, the length in the orthogonal direction will not be constant. For a more accurate judgment, it is better not to sense the length of the fabric body at the same time as sensing its conveyance.

[0018] Therefore, the inventors came up with the idea of ​​measuring the degree of shrinkage in a direction perpendicular to the conveying direction after a predetermined time has elapsed since the initial detection of the fabric body, as a means of determining whether the fabric body is suitable for shipping as a product, regardless of whether the fabric body is bent or has shrunk. With this configuration, the above-mentioned problems can be solved, and the present invention has been completed. The present invention is as follows.

[0030] The present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the present embodiment. Various embodiments described below may be combined. The embodiment described below shows an example of a shrink-cloth body dispensing device. The operation of the shrink-cloth body dispensing device according to the embodiment is executed by reading a program installed in or recorded in a storage device of a general-purpose computer connected to the shrink-cloth body dispensing device.

[0031] 1. First Embodiment As shown in Figures 1 to 9, the shrinkable cloth body dispensing devices 1 and 2 according to the first embodiment are devices that dispense shrunk shrinkable cloth bodies 20-1 and 20-3 from among substantially rectangular cloth bodies 10-1, 10-2, 20-1, 20-2, 20-3, and 20-4 (hereinafter, the cloth bodies are collectively referred to as "cloth body 10") being transported on a belt conveyor 11.

[0032] 1 to 9, the shrink cloth body dispensing devices 1 and 2 include a belt conveyor 11, a plurality of sensors 12a to 12i (hereinafter, the sensors may be collectively referred to as "sensor 12"), and a dispensing device 14. Each component will be described in detail below.

[0033] (1) Cloth body Examples of the fabric body 10 include, but are not limited to, linen products such as sheets and towels. For example, if the fabric body 10 is a sheet or towel, it is washed, dried by heat pressing using a roll ironer, or the like, and reused.

[0034] The fabric body 10 is transported in a semi-dry state, from when it is very wet after washing until drying is complete, while being subjected to tensile stress in the transport direction 13. Therefore, as a result of repeated washing and drying, the fabric body 10 may stretch slightly in the transport direction 13, and the middle portion of the shrunken fabric body 20-1 may shrink, causing deformation into a slightly curved shape in the width direction perpendicular to the transport direction 13, as shown in Figs. 4 to 6, for example. Therefore, in order to minimize deformation of the fabric body 10, and in this embodiment, to suppress shrinkage as much as possible, it is preferable that the fabric body 10 has sewn portions 10-1a, 10-2a, 20-1a, and 20-2a (hereinafter, occasionally referred to as "sewn portions 10a"), and is transported so that the sewn portions 10a face in a direction perpendicular to the transport direction. 4 to 6, the curve of the middle portion of the fabric body 20-1 is exaggerated to make it clear that the middle portion is curved.

[0035] However, even if the fabric body 10 is conveyed so that the sewn portion 10a faces the perpendicular direction, shrinkage in the perpendicular direction is unavoidable. As in the fabric body 20-1, the side edges in the conveying direction 13 are curved, and the length in the direction perpendicular to the conveying direction 13 may not be constant, resulting in a shrunk shape. Furthermore, corners may bend during conveyance. The fabric body 10 in this embodiment includes fabric bodies that are subject to deformation due to such bending and shrinkage.

[0036] The fabric body 10 is substantially rectangular, but includes contracted fabric bodies 20-1 and 20-3 that have been shrunk and recessed. As shown in Fig. 3, to determine whether the fabric body 10 has shrunk, after a predetermined time has passed since the central sensor 12a located in the center of the sensors 12 sensed the fabric body 10-1, the end sensors 12b to 12i of the sensors 12 other than the central sensor 12a are activated to sense the fabric body 10-1. Then, the number of end sensor detections by the end sensors 12b to 12i that sensed the fabric body 10-1 can be compared with a predetermined threshold value to determine the degree of contraction of the fabric body 10-1.

[0037] For example, in the case of Figure 3, the width of the fabric body 10-1 is the same as the distance from the end sensor 12b to the end sensor 12i, so all of the end sensors 12b to 12i detect the fabric body 10-1. Therefore, the number of end sensors detected is eight. If the predetermined threshold is six, the fabric body 10-1 is not dispensed by the dispensing device 14 and is treated as a product. The threshold will be described in detail below.

[0038] The fabric body 10 may have rounded corners. It may be rectangular or square. The shape of the fabric body may be rectangular. Although the fabric body is made of cloth, even synthetic fibers commonly used in linen products are included in the fabric body of this embodiment.

[0039] (2) Belt conveyor The shrunken cloth body dispensing devices 1 and 2 according to this embodiment include a belt conveyor 11 that transports the cloth body 10. The width of the belt conveyor 11 is preferably such that the cloth body 10 does not protrude from the belt conveyor 11. For example, if the cloth body 10 is a sheet, the length of the side edge portion having the sewn portion 10a is generally constant before shrinkage. Therefore, the width of the belt conveyor 11 only needs to be slightly larger than the length of the sewn portion 10a.

[0040] The conveying speed of the belt conveyor 11 may be controlled by the control device 15 and is appropriately adjusted by settings. It may be in the range of 10 to 100 cm / sec. A general introduction mechanism (not shown) may be provided on the upstream side of the belt conveyor 11 to introduce the fabric body 10 dried by the roll ironer.

[0041] (3) Multiple sensors A plurality of sensors 12a to 12i are provided above the belt conveyor 11. The plurality of sensors 12 are provided above the belt conveyor 11 in a direction perpendicular to a conveying direction 13, which is the direction in which the belt conveyor 11 conveys the object. The plurality of sensors 12 are also arranged in a direction perpendicular to the conveying direction 13.

[0042] 1 to 9, only one row of sensors 12 is provided, but in order to more accurately detect the degree of shrinkage, multiple rows of sensors 12 may be provided in a direction perpendicular to the conveying direction. Also, the multiple sensors 12 may be arranged symmetrically in the perpendicular direction.

[0043] For example, as shown in FIG. 1, when the conveyed fabric body 10-1 starts to pass the sensor 12, the central sensor 12a located in the center of the sensor 12 detects the fabric body 10-1. The central sensor 12a is disposed approximately in the center in the width direction of the belt conveyor 11. After a predetermined time has elapsed since the central sensor 12a detected the fabric body 10, the end sensors 12b to 12i other than the central sensor 12a are activated to detect the fabric body 10. When multiple sensors detect the fabric body 10-1, the multiple sensors that detected it transmit detection signals. In this embodiment, the central sensor 12a is always activated, and the end sensors 12b to 12i are activated after the fabric body 10-1 is detected by the central sensor 12a and a predetermined time has elapsed.

[0044] The more sensors there are in the sensor 12, the better. Seven or more sensors are preferred, and nine or more may be arranged as shown in FIGS. 1 to 9, or eleven or more, or thirteen or more may be arranged. For example, as shown in FIGS. 1 to 9, when nine sensors are arranged, the sensor may be configured with one central sensor 12a and eight end sensors 12b to 12i. In this case, four end sensors 12b to 12i may be arranged symmetrically. When viewed from the conveyance direction 13, two or more sensors may be arranged symmetrically on each side of the central sensor 12a, at equal intervals. In order to accurately sense the degree of shrinkage in the direction perpendicular to the conveyance direction 13 in the fabric body 10-1, it is most preferred to arrange as many sensors as possible.

[0045] In order to reduce the number of sensors and more accurately detect the shrinkage of the fabric body 10, the end sensors 12b to 12i may be arranged densely at the end of the belt conveyor 11, as shown in, for example, Figures 4 to 6, 8, and 9. The end sensors 12b to 12i are preferably arranged on the fabric body 20-2 within 10 to 40% of the length in the orthogonal direction from the end in the direction perpendicular to the conveyance direction, as shown in, for example, Figure 8. With such an arrangement, the degree of shrinkage of the fabric body 20-2 can be more accurately detected. The shrinkage degree that is measured varies depending on the size of the fabric body 10 before shrinkage, but if the end sensors 12b to 12i are arranged within this range, the degree of shrinkage of a shrunk fabric body 10 of a predetermined size can be more accurately detected.

[0046] Furthermore, as shown in Figures 4 to 6, 8, and 9 to 11, when the end sensors 12b to 12i are densely arranged at the side edge of the belt conveyor 11, the end sensors 12b to 12i may be configured to be able to move appropriately depending on the size of the fabric body 10 being conveyed. That is, the end sensors 12b to 12i may be configured to be able to move in a direction perpendicular to the conveyance direction. The positions may be adjusted manually or may be controlled by the control device 15, which will be described later. The position adjustment means for the end sensors 12b to 12i may use, for example, a moving means for the inkjet head of an inkjet printer, or may be automatically controlled by the control device 15, which will be described later.

[0047] 10 and 11, the end sensors 12b and 12i on both ends may be disposed on the side ends of the belt conveyor 11. With this arrangement, even if the fabric body 20-4' is conveyed in a state where it is significantly shifted to one side of the belt conveyor 11, the fabric body 20-4' can be detected.

[0048] In addition, for example, when eight or more end sensors are provided, the end sensors 12b to 12i may be arranged at equal intervals as shown in Figures 1 to 3. If they are arranged at equal intervals, the degree of shrinkage of the fabric body 10 can be estimated without adjusting the positions of the end sensors 12b to 12i. The interval between the end sensors may be approximately 5 to 100 mm. If it is within this range, the unwinding of the fabric body 10 can be determined with high accuracy.

[0049] Furthermore, the end sensors 12b to 12i may be arranged in a row downstream of the central sensor 12a and upstream of the dispensing device 14. This is because it is better to have the end sensors 12b to 12i sense the degree of shrinkage of the fabric body 10 in the direction perpendicular to the conveying direction 13 after the fabric body 10 is sensed by the central sensor 12a. Even with this arrangement, the end sensors 12b to 12i still operate to sense the fabric body 10 after a predetermined time has elapsed since the fabric body 10 was sensed by the central sensor 12a.

[0050] To solve the problem of this embodiment, it is better not to arrange the end sensors 12b to 12i upstream of the central sensor 12a as in the conventional technology. This is because the conventional end sensors are used to determine the size of the fabric body, not to sense the degree of shrinkage of the fabric body. In other words, to determine the size of the fabric body, it is sufficient to sense the leading edge of the fabric body in the conveying direction, and it is not necessary to sense the leading edge after a predetermined time has elapsed since it was first sensed.

[0051] For example, as shown in Figure 9, if a significantly shrunk fabric body 20-3 is fed, and the end sensors 12b-12i are located upstream of the central sensor 12a, the upstream end sensors 12b-12i will detect the leading edge of the fabric body 20-3, resulting in the fabric body being determined to be normal. In order for the end sensors 12b-12i to detect the shrinkage of the fabric body 20-3, it is necessary for the end sensors 12b-12i to detect the fabric body 20-3 a predetermined time after the central sensor 12a detects the fabric body 20-3. Therefore, it is better not to locate the end sensors 12b-12i upstream of the central sensor 12a, as in the prior art.

[0052] 9, when the fabric body 20-3 has shrunk so much that it cannot be detected by the end sensors 12b to 12i, the number of detections by the end sensors becomes 0, and the fabric body 20-3 is dispensed from the conveying path. In this way, when the end sensors 12b to 12i are arranged closely to the end of the belt conveyor 11 as shown in FIGS. 4 to 6, it is possible to determine whether or not the fabric body 20-3 is dispensed even if it has shrunk so much as to be conveyed, as shown in FIG.

[0053] The predetermined time in this embodiment may be, for example, a time between 0.1 and 5.0 seconds, or may be a time between 0.2 and 5.0 seconds after the central sensor 12a detects the fabric body 10. For example, if it is set to 3.0 seconds, the end sensors 12b to 12i will detect the degree of shrinkage of the fabric body 10 in the direction perpendicular to the conveyance direction 13 3.0 seconds after the central sensor 12a detects the fabric body 10.

[0054] Alternatively, the predetermined time may be the time required for the fabric body 10 to reach a position between 10 and 50% of the length of the fabric body 10 in the conveying direction 13 to elapse, divided by the conveying speed of the belt conveyor 11. For example, if the distance the fabric body 10 has reached a position between 10 and 50% of the length of the fabric body 10 in the conveying direction 13 is 60 cm and the speed of the belt conveyor is 30 cm / sec, the predetermined time is 60 (cm) / 30 cm (cm / sec) = 2 seconds.

[0055] Furthermore, even if the corners of the fabric body 10 are bent, the bending will not be so large as to extend over the above-mentioned length range. Therefore, the predetermined time in this embodiment is the time required to more accurately sense the degree of shrinkage of the fabric body 10 in the orthogonal direction perpendicular to the conveying direction 13 of the fabric body 10 .

[0056] The plurality of sensors 12a to 12i used in this embodiment irradiate infrared rays or the like toward the fabric body 10 on the belt conveyor 11, and detect the fabric body 10 as it passes by.

[0057] (4) Dispensing device As described above, the dispensing device 14 is disposed downstream of the belt conveyor 11, and includes a mechanism for dispensing the cloth body 10 conveyed by the belt conveyor 11 from the conveying path of the cloth body. For example, as shown in Fig. 6, when a cloth body 20-1 whose end sensor detection number is less than a predetermined threshold approaches the dispensing device 14, the dispensing device 14 tilts downward, and the cloth body 20-1 is dispensed from the conveying path.

[0058] FIG. 7 is a side view of the belt conveyor 11 and the shrink cloth body dispensing device 2 according to this embodiment, showing a state in which the shrink cloth body 20-1 is dispensed in the direction of the arrow. FIG. 7 shows an example of the dispensing device 14. As shown in FIG. 7, the dispensing device 14 may be arranged in series with the belt conveyor 11, and may be configured so that a downstream portion 14a in the conveying direction 13 is movable up and down. When the dispensing device 14 is in the state shown in FIG. 7, the cloth body 20-1 whose end sensor detection count is less than a predetermined threshold is conveyed in the direction of the arrow 13-1. Then, as the cloth body 20-1 is conveyed downward in FIG. 7, it is dispensed from the conveying direction 13 in which it is conveyed as a product.

[0059] As described above, a shrunk cloth body 20-1 with a significant degree of shrinkage in the direction perpendicular to the conveying direction 13 has low commercial value as a linen product and should not be shipped as a finished product. On the other hand, a cloth body 10 that has not shrunk excessively but is conveyed with bent corners still retains sufficient commercial value as a finished product. For this reason, it is desirable to check the degree of shrinkage of each cloth and ship only those that have commercial value as a linen product. In the embodiment, a device or the like that can meet such demand can be provided.

[0060] (5) Predetermined threshold In this embodiment, the predetermined threshold value may be a value obtained by subtracting one or more sensors from the number of edge sensors located within a range equal to or less than the length of the fabric body 10 in the direction perpendicular to the conveyance direction before the fabric body 10 shrinks. For example, a case will be described in which the length of the fabric body 10 in the perpendicular direction is 2000 mm, and the length from the edge sensor 12i to 12b closest to the end of the belt conveyor 11 is 2000 mm. In this case, the threshold number of edge sensor detections may be set to eight. If the fabric body 10 shrinks slightly, the number of sensors detecting the fabric body 10 may be reduced to seven. However, if the fabric body 10 is, for example, a sheet, a slightly shrunken fabric body 10 will not interfere with bed making, so from a cost perspective, it is better to ship it as a product.

[0061] Therefore, for example, it will be explained that a fabric body 10 whose shrinkage in the direction perpendicular to the conveying direction exceeds 50 mm is treated as a fabric body to be discharged. When the fabric body 10 shrinks by more than 50 mm, the number of edge sensor detections detected by the fabric body 10 becomes at least one less than the threshold number of edge sensor detections, and the fabric body 10 is discharged.

[0062] In this way, in this embodiment, the degree of shrinkage can be determined based on the difference between the number of edge sensor detections, which is the number of edge sensors that detected the fabric body 10, and the number of edge sensor detections set as a threshold. If this difference is too large, the fabric body 10 is either subject to removal, or it is determined that the size of the fabric body 10 is not within the target size range, and the fabric body 10 can be transported as a product.

[0063] In this embodiment, the predetermined threshold is preferably a value obtained by subtracting 2 from the number of end sensors located within a range equal to or less than the length of the fabric body 10 in the orthogonal direction before shrinkage plus the spacing between adjacent end sensors 12b-12e or 12f-12i. This preferable predetermined threshold can be determined more accurately when two or more end sensors are arranged at equal intervals on each side of the fabric body 10 so as to be symmetrical about the central sensor when viewed from the conveyance direction 13 of the fabric body 10. Preferably, there are four or more end sensors on each side, and more preferably six or more. There is no particular upper limit on the number of end sensors arranged on each side, but it may be set appropriately depending on the length of the belt conveyor 11 in the orthogonal direction.

[0064] 10, the length in the orthogonal direction, which is the width of the fabric body 20-4, is 1800 mm, the length from end sensors 12c to 12h is 1800 mm, and the intervals between end sensors 12b to 12e or 12f to 12i are each 50 mm, and a situation will be described in which a detection is performed when the length of the fabric body 20-4 in the orthogonal direction decreases by more than 50 mm. In this case, the number of reference end sensors for determining the threshold value is a total of six, from end sensor 12c to end sensor 12h, within a range of 1850 mm, which is the length of the fabric body 20-4 in the orthogonal direction, 1800 mm, plus the interval of 50 mm between end sensor 12c and end sensor 12d.

[0065] For example, as shown in Fig. 10, when the fabric body 20-4' is conveyed in a state where it is shifted to the left side in the conveying direction 13, it is preferable to add 50 mm to the right side in the conveying direction 13. On the other hand, when the fabric body 20-4' is conveyed in a state where it is shifted to the right side in the conveying direction 13, it is preferable to add 50 mm to the left side. In this way, by adding the spacing between the end sensors on the side opposite to the side where the fabric body 20-4' is shifted, it is possible to prevent the range of the added length from protruding from the belt conveyor 11.

[0066] Therefore, the predetermined threshold value for the number of edge sensors detected may be 6 (the number of reference edge sensors) - 2 = 4. The reason why the number obtained by subtracting 2 from the number of reference edge sensors is used as the threshold value for the number of edge sensors is as follows.

[0067] As in the case of the fabric body 20-4 in Figure 10, when each of the side edges passes directly under the end sensor 12c and the end sensor 12h, a total of six end sensors 12c to 12h detect the fabric body. However, if the fabric body 20-4 shrinks even slightly, the end sensors 12c and 12h do not detect the fabric body 20-4, and only a total of four end sensors 12d to 12g detect the slightly shrunk fabric body. In order to ensure that such slightly shrunk fabric bodies are treated as products, it is preferable to pull "two pieces" rather than "one piece."

[0068] When the predetermined threshold is set in this manner, even if the center of the fabric body 20-4' is conveyed off-center on the belt conveyor 11, as shown in the fabric body 20-4' in FIG. 10, the fabric body 20-4' as a product will not be dispensed. Furthermore, even if the fabric body 20-4' slightly shrinks, the slightly shrunk fabric body will not be dispensed. This is because: As shown in FIG. 10, the right edge of the fabric body 20-4' passes between the end sensor 12c and the end sensor 12d. Also, the left edge of the fabric body 20-4' passes between the end sensor 12h and the end sensor 12i. In such a case, the number of end sensor detections is five. Therefore, it is preferable to set the threshold value for the number of end sensor detections to 6 - 2 = 4.

[0069] A case where the fabric body 20-4' in FIG. 10 is conveyed at a position even closer to the end sensors will be described with reference to FIG. 11. For example, as shown in FIG. 11, when the side edge of the fabric body 20-4'' passes a position close enough to be undetectable by the end sensors 12d and 12i, the following situation is assumed. For example, if the fabric body 20-4'' shrinks slightly by less than 50 mm, the end sensor 12d will not detect the fabric body, and a total of four end sensors, end sensors 12e to 12g, will detect the fabric body. If the number of end sensors as the threshold is set to five, which is the reference number of six end sensors minus one, even a slight shrinkage, as described above, will cause the number of detected end sensors to become four, and the fabric body may be subject to dispensing. However, as described above, if the threshold number of detected end sensors is set to four, which is the reference number of end sensors minus two, fabric bodies with four detected end sensors will be conveyed as products without being dispensed.

[0070] Furthermore, a more preferable mode in which such threshold values ​​are set is one in which, when viewed from the conveying direction, two or more edge sensors are arranged at equal intervals on each side so as to be symmetrical about the central sensor 12a, and two or more edge sensors are arranged within a range of the length of the fabric body 10 in the orthogonal direction before it shrinks plus the interval between the edge sensors, and one or more edge sensors on each side are arranged outside this range of length. In this mode, even if the center of the fabric body 10 is significantly shifted and the fabric body 10 is transported close to either end of the belt conveyor 11, the number of detections by the edge sensors is not unnecessarily reduced, and the degree of shrinkage of the fabric body 10 can be determined.

[0071] In this embodiment, the dispensing device 14 may not dispense the fabric body from the conveying path if the number of end sensors is two or more less than the predetermined threshold value. When fabric bodies are introduced into the shrink fabric body dispensing device regardless of their size, for example, only sheets of size L or larger may be inspected, and sheets of size S may be considered as products. In this case, the threshold value may be set to a value three or more smaller, or four or more smaller, depending on the size of the fabric body 10.

[0072] In this embodiment, if the number of detected end sensors is two or more times greater than the threshold value, all of them are treated as products, so it is possible to inspect only S-size fabric bodies 10 and transport L-size or larger sheets as products. As with the above, this can be set to a value three or more times smaller, or four or more times smaller, depending on the size of the fabric body 10.

[0073] (6) Control device The shrunken cloth material dispensing apparatus 1 according to this embodiment may include a control device 15 that controls the shrunken cloth material dispensing apparatus 1. The control device 15 is a so-called computer, and controls the operation of the shrunken cloth material dispensing apparatus 1. The control device 15 will be described in detail below.

[0074] (5-1) Hardware configuration of the control device 12 is a diagram showing the hardware configuration of the control device 15 constituting the shrink cloth body dispensing device according to this embodiment. The control device 15 includes a CPU (Central Processing Unit) 15a that performs various processes, a memory 15b, a nonvolatile storage device 15c, an input device 15d such as a keyboard or a microphone, a monitor 15e, an input / output interface 15f, and a clock 15g.

[0075] The CPU 15a loads the program stored in the storage device 15c into the memory 15b and executes it. Each function described below is executed by the CPU 15a. The storage device 15c stores various data in addition to the program. The storage device 15c is a non-volatile memory such as a ROM (Random Access Memory), or a HDD that can be connected externally to the arithmetic device 50. Any medium capable of storing a program may be used, including magnetically or optically storing media such as a floppy disk (registered trademark) or a CD-ROM.

[0076] The programs stored in the storage device 15c are loaded into the memory 15b. The input device 15d is a device for inputting information. The execution results of the CPU 15a are displayed on the monitor 15e. The input / output interface 15f is an interface for receiving sensed data from the sensor 12 and transmitting data to an external device.

[0077] The clock 15g can be set to a time by synchronization using a computer network, etc. In this embodiment, it can be used as a timer for measuring a predetermined time after receiving initial sensing data from the central sensor 12a. For example, when the clock 15g receives data for a predetermined time that is input via the input / output interface 15f and stored in the storage device 15c, the clock 15g transmits a predetermined time elapsed signal to a control device (described later) after the predetermined time has elapsed due to the timer function of the clock 15g. The following describes in detail the functions of the control device 15. Note that the embodiments can be combined with each other and are not limited to the aspects described in each embodiment.

[0078] (5-2) Functional configuration of the control device FIG. 13 is a diagram showing the functional configuration of the control device 15 constituting the shrink cloth body dispensing device 1 according to this embodiment. The control device 15 includes a central sensor detection signal receiving unit 150a, a predetermined time data transmitting unit 150b, a predetermined time lapse signal receiving unit 150c, an end sensor activation signal transmitting unit 150d, an end sensor detection signal receiving unit 150e, an end sensor detection count acquiring unit 150f, a comparing unit 150g, and a dispensing instruction unit 150h. These functions are realized by cooperation of the hardware resources described above. Each functional configuration will be explained using FIGS. 1 to 3, 5 to 7, and 12 to 14.

[0079] (5-3) Operation of the control device 14 is a flowchart of a method for discharging a shrunken cloth body according to an embodiment. The following step numbers correspond to the step numbers shown in FIG. First, as shown in FIG. 1, when the leading edge of the fabric body 10-1 reaches the central sensor 12a and the central sensor 12a detects the fabric body 10-1, the central sensor detection signal receiving unit 150a receives the central sensor detection signal from the central sensor 12a (S151).

[0080] After the central sensor detection signal receiving unit 150a receives the central sensor detection signal, the predetermined time data transmitting unit 150b reads out the predetermined time data stored in advance in the storage device of Fig. 12 and transmits it to the clock 15g (S152). After a predetermined time has elapsed since the central sensor detection signal receiving unit 150a received the central sensor detection signal, more specifically, after the predetermined time data transmitting unit 150b transmits the predetermined time data to the clock 15g, the predetermined time elapse signal receiving unit 150c receives a predetermined time elapse signal from the clock 15g (S153).

[0081] After the predetermined time lapse signal receiving unit 150c receives the predetermined time lapse signal, the end sensor actuation signal transmitting unit 150d transmits an actuation signal to the end sensors 12b to 12i (S154). The end sensor sensing signal receiving unit 150e receives an end sensor sensing signal transmitted from the end sensor that sensed the fabric body 10-1 among the end sensors 12b to 12i due to the actuation of the end sensors 12b to 12i (S155).

[0082] For example, as shown in Fig. 2, when all of the end sensors 12b to 12i detect the fabric body 10-1, the end sensor detection signal receiving unit 150e receives end sensor detection signals from all of the end sensors 12b to 12i. Also, as shown in Fig. 5, when only the end sensors 12e and 12f detect the fabric body 20-1, the end sensor detection signal receiving unit 150e receives end sensor detection signals only from the end sensors 12e and 12f.

[0083] The edge sensor detection number acquiring unit 150f acquires the edge sensor detection number from the number of edge sensor detection signals received by the edge sensor detection signal receiving unit 150e (S156). For example, the edge sensor detection signal includes information about the edge sensor, and it is possible to identify the edge sensor that transmitted the edge sensor detection signal. The edge sensor detection number acquiring unit 150f can acquire the number of edge sensor detections that transmitted the edge sensor detection signal as the number of edge sensor detections that detected the fabric body 10.

[0084] The comparison unit 150g obtains a predetermined threshold for comparing the number of edge sensor detections from the storage device 15c, and compares the number of edge sensor detections with the threshold (S157). If the comparison result shows that the number of edge sensor detections is smaller than the threshold (yes in S157), the dispensing instruction unit 150h operates the dispensing device 14 by transmitting a dispensing signal to the dispensing device 14. As the dispensing device 14 operates as shown in Figures 6 and 7, the cloth body 20-1 is conveyed in the direction of the arrow shown in Figure 7 and is dispensed from the conveyance path.

[0085] On the other hand, if the number of detections by the end sensor is equal to or greater than the threshold value (S157, no), it is determined that no significant shrinkage is observed, and the process ends. In this case, as shown in Figure 3, the fabric body 10-1 is transported downstream of the shrunken fabric body discharging devices 1 and 2.

[0086] (5-4) Desired operation of the control device In the embodiment of the shrink cloth body dispensing device, it is preferable to set a threshold value as described above so that the product can be shipped even if the conveying position of the conveyed cloth body is offset from the center of the belt conveyor when viewed from the conveying direction.

[0087] 15 is a diagram showing the functional configuration of a control device constituting a shrink cloth body dispensing device according to a preferred embodiment. As shown in FIG. 15, the control device 160 includes a reference end sensor number calculation unit 160i and a threshold value calculation unit 160j, as compared with FIG. 13.

[0088] Fig. 16 is a flowchart of a method for dispensing a shrunken cloth body according to a preferred embodiment. As with the above-described preferred embodiment of the threshold value, this differs from Fig. 14 in that the threshold value is calculated based on information about the cloth body 10 and information about the end sensors 20b to 20i. Steps S161 to S166 in Fig. 16 are the same as those in Fig. 14, and therefore will not be described here.

[0089] The reference end sensor number calculation unit 160i acquires the orthogonal length of the fabric body 20-4' before shrinkage, as well as the interval and position information of the end sensors, which are previously stored in the storage device 15c via the input / output interface 15f, and calculates the number of reference end sensors (S169). Specifically, for example, in FIG. 10, if the orthogonal length of the fabric body 20-4' is 1800 mm, this length is stored in the storage device 15c. Also, if the end sensors 12b, 12c, 12d, and 12e are arranged at 50 mm intervals from the right end in the conveying direction 13, and the end sensors 12i, 12h, 12g, and 12f are arranged at 50 mm intervals from the left end in the conveying direction 13, the position of each end sensor is stored in the storage device 15c as the distance from the end of the belt conveyor 11.

[0090] In this case, the number of reference end sensors for determining the threshold value is a total of six, from the end sensor 12c to the end sensor 12h, within a range of 1850 mm, which is the length of the fabric body 20-4' in the orthogonal direction, plus 50 mm, the interval between the end sensors, on the right side in the conveying direction 13. Therefore, even if the fabric body 20-4' or the fabric body 20-4'' shown in Figures 10 and 11 is transported on either the left or right side of the belt conveyor 11, the reference end sensor number calculation unit 160i can calculate the number of reference end sensors in this way.

[0091] The threshold calculation unit 160j calculates the threshold by subtracting 2 from the number of reference end sensors calculated by the reference end sensor number calculation unit 160i (S170). In the above example, the number of detected end sensors, which is the predetermined threshold, may be 6 (number of reference end sensors) - 2 = 4.

[0092] The comparison unit 160g compares the edge sensor detection count acquired by the edge sensor detection count acquisition unit 160f with the threshold calculated by the threshold calculation unit 160j (167). The rest of the description is the same as in FIG. 14, so it will be omitted. [Explanation of symbols]
