Description

According to the present invention, the roll spreader and the roll spread method prepare for cutting by feeding out a cloth or the like to a required length while the main body of the roll spreader for storing the original fabric moves back and forth on the roll spread table. Regarding.

Conventionally, the dough such as cloth is unwound by pulling it out from the roll-shaped original fabric, the dough is unwound to the required length, cut, and laminated and placed at a predetermined position on the rolling table. The spreader is known. The dough that has been unwound from the original fabric in the rolling machine is unwound by the feeding roller and laminated on the rolling table, but there is a slip between the feeding roller and the dough. In consideration of this slippage, the spreader is set so that the amount of the dough fed by the feeding roller is larger than the amount of movement of the rolling machine main body. This slip differs depending on the weight and material of the fabric, even if it is the same material, depending on the lot at the time of manufacture, and even if it is the same fabric, it slips between the fabric wound on the outside and the fabric wrapped on the inside. May be different. Due to the fact that the sliding between the feeding roller and the dough is not constant, the spreading length of the dough being fed to the spreading table is also affected. If the slip is large, the length of the stretched fabric that is actually delivered is short, and the stretched fabric is placed while being pulled. On the other hand, if the slip is small, the length of the stretched fabric will be long, which may cause wrinkles. As a result, the slippage of the dough affects the edges of the stretched dough and the edges of the dough are not aligned.

Examples of the prior art of the roll spreader and the roll spread method include the following publications.
According to Patent Document 1 (Special Fair 6-99077), the loosened state of a piece of cloth is detected by a plurality of photoelectric sensors at the time of spreading, and the repelling means, the piece feeding means, and the rewinding machine traveling means are provided according to the detected values. It is described that the rolling state of the dough is kept in the best state by controlling the speed of each.
However, the present invention is a feed bag control in which the loosened state of a piece of cloth is detected by a photoelectric sensor and then the cloth feeding means, the spreading machine traveling means, and the like are controlled. Therefore, even if a relaxed state is detected near the end of the extension, there will be a delay in bringing the relaxed state to an appropriate state. Therefore, the relaxed state is not always an appropriate state at the end of the extension. If the dough is cut, the edges of the dough cannot be aligned.

Patent Document 2 (Patent No. 2762217) continues to feed the dough even if the roll spreader main body stops at the end of roll spread, and the traveling speed of the roll spreader main body is relatively reduced. As a result, it is described that the dough is in a state of hanging straight at the end of placing the dough, and cutting with a horizontal cutter is easy and highly accurate.
In this way, if the dough is cut with a cutter while the dough is hung straight at the end of placement, it is possible that the edges of the dough can be aligned in addition to facilitating the cutting with the cutter. However, the curvature at the time of bending differs depending on the hardness of the dough to be rolled. Therefore, even when the dough is hung straight, it is difficult to align the edges of the dough after cutting with a cutter due to the difference in the hardness of the dough. In addition, it is unknown how long the dough can be continuously fed after the main body of the spreader is stopped so that the dough can be hung straight.

It consists of 3. The traveling carriage 3 is driven by a traveling drive motor 4. On the right side of the upper surface of the traveling carriage 3, a rolling-off portion 7 on which the original fabric 6 wound with the fabric 5 is placed is provided, and on the left side of the upper surface of the traveling carriage 3, a feeding portion 8 of the fabric 5 is provided. Further, on the left side of the traveling carriage 3, a lifter 9 that can be raised and lowered is provided with a fabric guide plate 10, a cutter unit 11, a sensor unit 12, and the like. The controller 13 performs various controls on the spreader 1.

In the repelling portion 7, the original fabric 6 is placed on the two rollers 14 and 14, and the rollers 14 and 14 are rotationally driven by the repelling drive motor 15. The feeding portion 8 is provided with a feeding roller 17 that is rotationally driven by the feeding motor 16. A space 18 for release is formed between the unfolding portion 7 and the feeding portion 8, and the tension acting on the roll-shaped dough 5 is released. After the dough 5 wound around the original fabric 6 is unwound by the antiphrasis portion 7, the tension is removed in the antiphrasis space 18 and the fabric 5 is sent to the feeding portion 8. Further, the dough 5 fed by the rotational drive of the feeding roller 17 of the feeding portion 8 is fed onto the spreading table 2 via the dough guide plate 10 provided on the lifter 9 which can be raised and lowered. The lifter 9 is formed so as to be able to move up and down by a lift motor 19.

In addition to the dough guide plate 10, the lifter 9 is provided with a cutter unit 11 provided with a cutter 20 for cutting the dough 5 at the end of rolling, and a sensor unit 12. The sensor unit 12 includes a dough edge sensor 21 that detects the position of the dough edge on the dough guide plate 10, and a slack that measures the amount of slack of the dough 5 that extends from the dough guide plate 10 to the dough roll table 2 at the end of the roll roll. A sensor 22 and a height sensor 23 that detects the height of the dough 5 laminated on the roll spread table 2 when starting the next roll roll are provided. The lifter 9 can be raised and lowered according to the height of the laminated dough 5, and can perform highly accurate rolling.

FIG. 2 is a diagram showing a schematic system configuration of the spreader 1. Reference numeral 24 denotes a CPU that performs various data processing, 25 is a ROM that stores various programs, 26 is a RAM that has a work memory that can be read and written, and 27 is a hard disk that stores extension data and the like. The ROM 25 is subjected to arithmetic processing such as updating the slack correction value, which will be described later, and the advance length at the start of spreading. Various data such as a slack amount setting value and a slack correction value are stored in the RAM 26. Reference numeral 28 denotes a bus, which does not distinguish between a data bus and other instruction buses, and is shown as one bus. Reference numeral 29 denotes an input / output interface. The drive circuit 30 controls the traveling drive motor 4 to perform reciprocating traveling on the spreading table 2 of the spreading machine 1. The drive circuit 31 controls the antiphrasis drive motor 15 to drive the rollers 14 and 14, so that the fabric 5 is unraveled from the original fabric 6. The dough 5 is fed by controlling the feeding drive motor 16 by the drive circuit 32 and driving the feeding roller 17. The drive circuit 33 controls a cutter drive motor (not shown) to cut the dough 5. The lift motor 19 is controlled by the drive circuit 34 to drive the lifter 9 up and down.

The fabric edge sensor 21 provided in the sensor unit 12 outputs a detection signal of the position of the fabric edge to the controller 13. The fabric edge sensor 21 detects the presence or absence of the fabric 5 at a predetermined position of the fabric guide plate 10, and in this embodiment, a photoelectric sensor is used. There are two types of photoelectric sensors, a reflective type and a transmissive type. In this embodiment, a reflective type photoelectric sensor is used. In order to detect the presence or absence of the fabric 5 at the predetermined position of the fabric guide plate 10, the predetermined position of the fabric guide plate 10 is made of a material such as a metal that reflects light or a reflective tape is attached. The light projected from the projector of the photoelectric sensor toward the fabric guide plate 10 is reflected if there is no fabric 5, and enters the receiver to recognize that the fabric 5 is not present. If there is a cloth at a predetermined position on the cloth guide plate 10, the projected light is not reflected by the cloth and the light receiver does not detect it, so that the presence of the cloth 5 is detected. It is also possible to use a transmissive type photoelectric sensor as the fabric edge sensor 21. In that case, a hole is formed at a predetermined position of the fabric guide plate 10, and a floodlight and a light receiver are provided so as to sandwich the hole of the fabric guide plate 10. By detecting the presence or absence of the dough 5 with the dough edge sensor 21 while driving the feeding roller 17, it is possible to align the dough edge with a predetermined position on the dough guide plate 10. It is also possible to obtain the position of the edge of the fabric from the image taken by a CCD camera or the like instead of the photoelectric sensor.

The slack sensor 22 measures the distance from the attachment position of the slack sensor 22 to the surface of the fabric at the slack portion 24 and outputs data. In this embodiment, as the sensor used for the slack sensor 22, a distance measuring sensor such as a laser distance measuring sensor is used. An infrared distance measuring sensor may be used instead of the laser distance measuring sensor. The height sensor 23 measures the distance in the height direction from the mounting position of the height sensor 23 to the cloth 5 placed on the spreading table 2 and outputs data. In this embodiment, the height sensor 23 will be described using a laser ranging sensor, but this may be an infrared ranging sensor or the like. In addition, a signal or the like from the operating means 25 for operating the spreading machine 1 is also input to the controller 13.

The flow of processing of the rolling roll method in the embodiment will be described with reference to the flowchart shown in FIG. 3 and the schematic diagram of the rolling roll operation shown in FIGS. 4 and 5. The extension processing in each step is executed under the control of the controller 13.

First, the process is started in step S1. The length of the dough 5 to be rolled, the number of layers, the running speed of the rolling machine 1 main body, and the like are set in advance. In step S2, the presence / absence of the fabric 5 at a predetermined position of the fabric guide plate 10 is detected by the fabric edge sensor 21. While driving the feeding roller 17 at a low speed, the cloth 5 on the cloth guide plate 10 is returned or fed, and the driving of the feeding roller 17 is stopped at the timing when the cloth edge sensor 21 switches from on to off or from off to on. As a result, the edge of the fabric can be aligned with the predetermined position. FIG. 4A schematically shows this rolling motion. The reason for aligning the edges of the fabric at a predetermined position in this way is to accurately match the spread length. At the end of rolling, the dough 5 is cut by the cutter 20 provided on the cutter unit 11, but depending on the dough 5, the dough 5 on the dough guide plate 10 is cut by the cutter 20 so that the weight of the dough 5 is eliminated. There is something that shrinks. In the case of such a dough 5, it is necessary to align the edges of the dough with a predetermined position before the start of rolling in order to perform rolling with an accurate rolling length.

In step S3, the distance A from the edge of the dough at the predetermined position to the position where the edge of the dough is placed at the time of spreading is first put out. FIG. 4B schematically shows this rolling motion. An example of how to obtain the distance A for first-out will be briefly described. The dough guide plate 10 is provided on a lifter 9 that can be raised and lowered, and the height of the dough guide plate 10 from the spreading table 2 can be grasped. Further, in this embodiment, the fabric guide plate 10 forms a slope of 45 degrees. The angle of the slope of the fabric guide plate 10 may be 30 degrees or 60 degrees, or may be changed according to the hardness of the spreading fabric 5. If the dough is fed out to the dough guide plate 10 along the slope by the first-out treatment, and even after passing the dough guide plate 10, the dough goes straight on the extension line of the slope and reaches the spreading table 2, the dough is fed out by the first-out treatment. The length of 5 can be calculated by about 1.4 times the height from the predetermined position on the edge of the dough to the spread table 2. This is an example in which the slope angle of the fabric guide plate 10 is 45 degrees. As long as the height and angle are known, it can be easily obtained using trigonometric functions, so the explanation for other angles will be omitted.

In step S4, rolling is performed at the set traveling speed of the rolling machine 1 main body and the feeding speed by the feeding roller 17. FIG. 4 (c) schematically shows this rolling motion. When the rolling machine 1 is running, the dough 5 is placed on the spreading table 2 by driving the feeding roller 17, but since there is a slip between the feeding roller 17 and the dough 5, the dough 5 is spread. The slack correction value is set so that the feed amount of the dough 5 by the feeding roller 17 is larger than the movement amount of the counter machine 1 main body at a predetermined ratio. For example, when the initial value of the slack correction value is set to 6%, the roller 17 is rotationally driven by a length 1.06 times the moving distance of the rebel machine 1. At the time of rolling, the traveling speed of the rolling machine 1 and the feeding speed by the feeding roller 17 are driven along a set speed curve. It is preferable that the traveling speed and the feeding speed are not changed according to the amount of slack of the slack portion 24 while the rebel machine 1 is traveling. When the amount of slack is constantly monitored at the time of rolling as in the prior art and the running speed and feeding speed of the rolling machine are changed at the time of rolling so that the amount of slack is constant, the control is not stable and the rolling is spread. Unstable tension will be applied to the fabric to be made. In particular, a problem may occur when spreading the roll at high speed.

In step S5, the amount of slack in the slack portion 24 is measured by using the slack sensor 22 in a state where the spread machine 1 is stopped at the spread end position. The slack sensor 22 measures the distance from the attachment position of the slack sensor 22 to the surface of the fabric at the slack portion 24. FIG. 4 (d) schematically shows this rolling motion.
In step S6, the slack amount set value stored in advance is compared with the actually measured distance, and the feeding roller 17 is driven so that the difference disappears, and the fabric 5 is moved. As a result, the amount of slack in the dough 5 at the end of rolling can be set to a set value. FIG. 5 (e) schematically shows this rolling motion.

In this embodiment, the slack amount set value is the amount of slack when the dough 5 extending from the spreading table 2 to the dough guide plate 10 at the slack portion 24 at the end of the spreading is at the same angle as the slope of the dough guide plate 10. Set value. Since the dough 5 to be fed out is fed out without applying tension, the slack portion 24 usually has more slack than the set value. In this case, the amount of slack can be adjusted to the set value by rotating the feeding roller 17 in the reverse direction and returning the dough 5 to the original fabric side. The amount of dough 5 returned in order to match the amount of slack during this operation is obtained from the amount of rotation of the feeding roller 17. The slack correction value is updated from the difference with respect to the extension length, and the amount of slack at the end of extension at the next extension is brought closer to the set value. For example, if the initial value of the slack correction value is extended by 6% and a large amount of slack appears, the slack correction value at the next extension is updated to 5% or the like so that the difference is reduced. When the amount of slack at the end of rolling is closer to the set value, the amount of returning the dough 5 is smaller and the efficiency of rolling is improved.
It is also possible to set the slack amount in a state where the dough 5 is slightly slackened in the slack portion 24. In that case, the feeding roller 17 is rotated forward or reversed depending on the slack amount at the end of rolling. With, the amount of slack can be adjusted to the set value. The setting value of the amount of slack may be appropriately set according to the dough to be rolled.

In step S7, the cutter 20 of the cutter unit 11 cuts the dough 5. FIG. 5 (f) schematically shows this operation. The dough 5 is cut near the tip of the dough guide plate 10 by the cutter 20, and the end portion of the dough 5 extending from the dough guide plate 2 to the dough guide plate 2 is dropped onto the dough table 2 by the dough cutting. Is done. After cutting the dough 5 with the cutter 20 at the end of rolling, the length C of the difference in the horizontal direction from the tip position of the dough guide plate 10 of the dough 5 rolled on the spreading table 2 to the end position of the dough is large. It will be postponed.

Explaining with an example of a simple calculation method, the dough 5 in the slack portion 24 before being cut by the cutter 20 at the end of the roll spread rises from the roll roll table 2 toward the dough guide plate 10, and the angle thereof is Approach the angle of the slope of the fabric guide plate 10. The height from the rolled dough 5 to the tip of the dough guide plate 10, that is, the height cut by the cutter 20, can be obtained from the value measured by the dough height sensor 23. From this height and the angle of the dough guide plate 10, the length of the dough 5 over the slack portion 24 can be easily calculated. The length obtained by subtracting the height from the tip of the dough guide plate 10 to the stretched dough 5 from the length of the slack portion 24 obtained in this way is C, and after cutting the dough, from the tip position of the dough guide plate 10. It is the horizontal length to the end position of the fabric.
When the dough 5 is rolled with a roll length of, for example, 1000 mm, the first-out length A obtained in step S3 and the length from the tip of the cut dough guide plate 10 to the end position of the dough described in step S7. The length subtracted from 1000 mm, which is the length of the roll that specifies the total length of C, can be calculated as the moving distance B of the main body of the roll spreader 1. As described above, since the heights required for the respective calculations of the lengths A and C are known in advance, it is necessary to calculate the spread start position and the spread end position of the roll spreader 1 main body before the roll spread start. It is possible.

In step S8, the main body of the spreader 1 is moved to the spread start position. At this time, the height sensor 23 measures the height to the upper surface of the dough spread on the spreading table 2, and raises the lifter 9 according to the measured value. The height to be raised may be raised by the height of the newly laminated fabric 5, but if the ears of the fabric 5 are overlocked, many fabrics 5 are laminated. Then, the ear portion of the fabric 5 may rise. Even in such a case, the height of the laminated dough 5 may be raised more than the height so that stable rolling can be performed. Even in this case, since the accurate height is obtained, the first-out length A obtained in step S3 and the length C from the tip of the cut dough guide plate 10 to the end position of the dough described in step S7 are calculated. It is possible to determine the spread start position and the spread end position of the roll spreader 1 main body. (Extended length L = "First-out length A" + "Length C from the tip of the dough guide plate after cutting to the end of the dough" + "Extended movement distance B")
When the lift of the lifter 9 is completed, the feeding roller 17 is driven while detecting the fabric edge with the fabric edge sensor 21 in the same manner as in step S2 to align the fabric edge with the predetermined position. FIG. 5 (g) schematically shows these rolling motions.

In step S9, as in step S3, the distance A from the dough edge at a predetermined position to the dough edge placing position at the time of spreading is obtained and the first-out is performed. FIG. 5 (h) schematically shows this rolling motion. In step S10, the main body of the rolling machine 1 is driven and the feeding roller 17 is driven to spread the dough 5. When the dough 5 is fed by the feeding roller 17, the dough 5 is driven on the already rolled dough 5 on the spreading table 2 by driving the feeding roller 17 based on the updated slack correction value obtained in step S4. I will put it on. FIG. 5 (i) schematically shows this rolling motion.

In step S11, it is determined whether or not the set number of doughs 5 have been rolled. If the set number of sheets has not been reached, the process proceeds to step S5 to continue the rolling process. When the set number of sheets is reached, the process proceeds to step S12 and the spreading process is completed.

In this embodiment, the slack correction value for the next roll spread is updated in step S6, but this is not always necessary, and the amount of returning the dough 5 at the roll spread end position updates the slack correction value. By returning the dough so that the amount of slack becomes a set value each time the dough 5 is rolled, the edges of the dough at the end of rolling can be aligned.
By rolling the dough 5 about 3 sheets, the sagging correction value becomes almost stable. The slack correction value may be updated every time after that, but the slack correction value may not be updated for the fourth and subsequent sheets. However, if the amount of slack at the end of rolling is detected by the slack sensor 22, and when the amount of slack exceeds the permissible range from the set value, the amount of slack is adjusted to the set value again and the slack correction value is updated. good.

Further, in the above embodiment, as a method of obtaining the difference between the spread length set value and the spread length obtained by the spread length measuring means, the amount of slack is measured by using a distance measuring sensor as the slack sensor 22. In addition to this method, the above difference can be obtained by actually measuring the length of the spread. For example, as a means for measuring the roll length, a method of measuring the roll length without contact when the fabric is rolled (using a laser Doppler sensor or the like) or a method of measuring the roll length by contacting an encoder or the like with the fabric can be considered. ..
