Description

  The present invention relates to a rolling device for rolling a noodle strip to a predetermined thickness.

  2. Description of the Related Art Conventionally, a rolling device has been used in which a plurality of pairs of rolling rollers are arranged and the noodle strips are rolled in stages by passing the noodle strips between these rolling rollers. In such a rolling apparatus, the thickness of the noodle strip after rolling is measured by an optical sensor or the like, and the thickness of the noodle strip is controlled by adjusting the gap between the pair of rolling rollers based on the measured value. Things have been done. Furthermore, in order to prevent the vibration of the noodle band that is generated when the noodle band is cut at a certain length after rolling from affecting the thickness control as a disturbance in the measured value of the noodle band thickness, The maximum width of the measured values is ranked into a predetermined number, the frequency of the rank corresponding to the measured values obtained continuously for a certain time is counted, and the measured value corresponding to the rank having the maximum frequency is calculated. A measurement value processing method that defines a measurement value at a certain time has been proposed (see, for example, Patent Document 1).

The interval between 20a and moving roller 20b is set to a predetermined size. Although the specific configuration of the roller moving unit 20c is arbitrary, for example, a servo motor that supplies a driving force for movement, a worm gear for converting the rotation operation of the servo motor into a straight movement operation, or a moving roller 20b from the worm gear. It is possible to configure using a push screw or the like for transmitting the driving force to. By passing the noodle strip through the gap between the fixed roller 20a and the moving roller 20b rotating in opposite directions, the noodle strip is rolled to a thickness corresponding to the interval between the fixed roller 20a and the moving roller 20b. .

  The noodle thickness sensor 21 is a sensor for detecting the thickness of the noodle strip rolled by the rolling roller 20. The specific configuration of the noodle thickness sensor 21 is arbitrary. For example, the noodle thickness sensor 21 emits pulsed light toward the noodle band, receives reflected light reflected by the noodle band, and determines the noodle band from the time difference between light emission and light reception. A known sensor such as an optical sensor that detects the distance to the sensor and detects the thickness of the noodle strip based on the detected distance can be used. Information indicating the thickness of the noodle strip detected by the noodle thickness sensor 21 is input to the adjustment unit 23.

  The storage unit 22 is a storage unit for storing various data necessary for operating the rolling apparatus 2, and includes a restoration rate database 22a (in the following description, “database” is expressed as “DB”). Yes. The specific configuration of the storage unit 22 is arbitrary, and for example, a RAM (Random Access Memory), a hard disk, or the like can be used (all not shown). The specific contents of the information stored in the restoration rate DB 22a will be described later.

  The adjustment unit 23 is an adjustment unit that adjusts the target thickness of the noodle band to be rolled by the rolling device 2 based on information input from the input unit 24 and information stored in the storage unit 22.

  The display unit 25 is a display unit that displays various types of information (for example, information stored in the restoration rate DB 22a) related to the setting of the rolling device 2. The specific configuration of the display unit 25 is arbitrary, and for example, a flat panel display such as a liquid crystal display can be used.

(Configuration-rolling device-information stored in restoration rate DB)
Next, specific contents of the information stored in the restoration rate DB 22a described above will be described. FIG. 4 is a table showing information stored in the restoration rate DB 22a. The restoration rate DB 22a is restoration rate information storage means for storing information on the restoration rate of the thickness of the noodle strip after being rolled by the rolling roller 20, and as illustrated in FIG. “Noodle variety” and “restoration rate” are provided, and information corresponding to these is stored in association with each other. The information stored corresponding to the item “noodle varieties” is type information for uniquely identifying the type of the noodle band, and for example, the name of the noodle variety such as “Udon” or “Soba” is used. Can do. The information stored corresponding to the item “restoration rate” is restoration rate information for specifying the restoration rate of the noodle strip after being rolled by the rolling roller 20 for each of a plurality of types of noodle strips. A numerical value indicating the percentage of increase in the thickness of the noodle strip after a predetermined time with respect to the thickness immediately after being rolled can be used. Each information stored in the restoration rate DB 22a is input by an operation input via the input unit 24, and is stored in the restoration rate DB 22a.

(Processing content)
Next, the adjustment process performed by the adjustment unit 23 will be described. The adjustment process is a process for adjusting the target thickness of the noodle band in accordance with the type when the type of the noodle band to be rolled is specified by the rolling device 2. FIG. 5 is a flowchart showing the flow of adjustment processing executed by the adjustment unit 23 (steps are abbreviated as “S” in the description of each processing below).

  When the noodle making facility 1 is operated to manufacture the noodles, when the rolling device 2 is activated by a predetermined activation operation, the adjustment unit 23 includes the type information of the noodle band to be rolled by the rolling device 2, and It waits until the required thickness finally calculated | required with respect to a noodle strip is input via the input part 24 (SA1).

  When the noodle band type information and the requested thickness are input (SA1, Yes), the adjustment unit 23 specifies the noodle variety corresponding to the input type information (SA2), and is restored based on the specified noodle type. With reference to the rate DB 22a, it is determined whether or not the information on the noodle variety is stored in the restoration rate DB 22a (SA3). As a result, when the information regarding the specified noodle variety is stored in the restoration rate DB 22a (SA3, Yes), the adjustment unit 23 acquires the restoration rate information stored in association with the noodle variety (SA4). . For example, in the example illustrated in FIG. 4, when the specified noodle variety is “Udon”, information indicating “2.0%” is acquired as the corresponding restoration rate.

  On the other hand, when the information regarding the specified noodle variety is not stored in the restoration rate DB 22a (SA3, No), the adjustment unit 23 causes the display unit 25 to display that the restoration rate information is to be input (SA5). Thereafter, the adjustment unit 23 waits until restoration rate information is input via the input unit 24 (SA6).

  When the restoration rate information is acquired in SA4 or when the restoration rate information is input in SA6 (SA6, Yes), the adjustment unit 23 calculates the target thickness of the noodle strip based on the restoration rate information. (SA7).

  In addition, about the adjustment content of target thickness, it can determine arbitrarily. For example, in the case where the final required thickness required for the noodle strip after thickness restoration is t1, the target thickness of the noodle strip immediately after rolling by the rolling roller 20 is t2, and the restoration rate specified by the restoration rate information is r. The target thickness t2 can be obtained as t2 = t1 × (100−r) / 100.

  After obtaining the target thickness, the adjusting unit 23 operates the roller moving unit 20c based on the target thickness (SA8). The specific content for operating the roller moving unit 20c is arbitrary. For example, the roller moving unit 20c is operated so that the distance between the moving roller 20b and the fixed roller 20a is equal to the target thickness obtained in SA7 above. Can be adjusted. Alternatively, the distance between the moving roller 20b and the fixed roller 20a may be equal to a value obtained by performing an operation such as adding, subtracting, or multiplying a predetermined value to the target thickness.

  Further, when the rolling of the noodle strip is started in the rolling device 2 after the target thickness is calculated, the adjusting unit 23 determines the thickness of the noodle strip immediately after rolling specified based on the information input from the noodle thickness sensor 21. Feedback control is performed on the roller moving unit 20c so that is equal to the target thickness.

(effect)
As described above, according to the first embodiment, based on the restoration rate information stored in the restoration rate DB 22a, different restoration rates are identified according to the type of noodles to be rolled by the rolling device 2, and the identified restoration rate is determined. In consideration of the above, the target thickness of the noodle strip immediately after rolling by the rolling roller 20 is calculated, the roller moving unit 20c is operated according to the calculated target thickness, and the interval between the fixed roller 20a and the moving roller 20b is adjusted. . Thereby, the thickness of the noodle strip after the thickness is restored can be controlled to an appropriate value. Further, since different restoration rates for each of the plurality of noodle varieties are stored in the restoration rate DB 22a, even when rolling noodle strips of different varieties, type information indicating the varieties is input via the input unit 24. The target thickness can be easily readjusted to an appropriate value according to the product type.

[Embodiment 2]
Next, a second embodiment will be described. In this form, the restoration rate information storage means stores the environment information.

  The configuration of the second embodiment is substantially the same as the configuration of the first embodiment unless otherwise specified. The configuration substantially the same as the configuration of the first embodiment is the same as that used in the first embodiment. The same reference numerals and / or names are attached as necessary, and the description thereof is omitted.

(Configuration-rolling device-information stored in restoration rate DB)
The contents of the information stored in the restoration rate DB 22a in the second embodiment will be described. FIG. 6 is a table showing information stored in the restoration rate DB 22a. As illustrated in FIG. 6, the restoration rate DB 22a according to the first embodiment includes “temperature”, “humidity”, “noodle variety”, and “restoration rate” as DB items, and information corresponding to these items is provided. Stored in association with each other. The information stored corresponding to the items “temperature” and “humidity” is environmental information that specifies the temperature and humidity of the environment in which the noodle strip is rolled by the rolling roller 20. The specific content of the environmental information is arbitrary, and as illustrated in FIG. 6, information (such as “20 to 25” in FIG. 6) specifying a predetermined temperature range divided into a plurality of items Can be stored in association with each other. Similarly, information for specifying a predetermined humidity range divided into a plurality of pieces (such as “less than 30” or “more than 30 and less than 65” in FIG. 6) can be stored in association with the item “humidity”. In addition, these environmental information is acquired by well-known sensors (all are abbreviate | omitted illustration), such as a temperature sensor and a humidity sensor arrange | positioned around the rolling apparatus 2, for example, and is input into the restoration rate DB22a from the said sensor.

(Processing content)
Next, the adjustment process performed by the adjustment unit 23 will be described. FIG. 7 is a flowchart showing the flow of adjustment processing executed by the adjustment unit 23.

  When the noodle making equipment 1 is operated to manufacture noodles, when the rolling device 2 is activated by a predetermined activation operation, the adjusting unit 23 determines the temperature in the environment in which the noodle strip is rolled from the temperature sensor and the humidity sensor. And waits until information indicating humidity is input (SB1).

  When information indicating temperature and humidity is input (SB1, Yes), the adjusting unit 23 specifies the temperature and humidity of the rolling environment based on the input information (SB2), and includes the specified temperature and humidity. It is determined whether the information is stored in the restoration rate DB 22a (SB3). As a result, when the environment information including the specified temperature and humidity is stored in the restoration rate DB 22a (SB3, Yes), the adjustment unit 23 sets the type information of the noodle band to be rolled by the rolling device 2 and the noodle It waits until the required thickness finally calculated | required with respect to a belt | band | zone is input via the input part 24 (SB4). On the other hand, when the environment information including the specified temperature and humidity is not stored in the restoration rate DB 22a (SB3, No), the adjustment unit 23 causes the display unit 25 to display a prompt to input restoration rate information ( SB8). Since the subsequent processes from SB4 to SB11 are the same as the processes from SA1 to SA8 described in the first embodiment, the description thereof is omitted.

  In addition, even after the start of rolling in the rolling device 2, the adjusting unit 23 specifies the temperature and humidity in the environment in which the noodle strip is periodically rolled, and specifies the restoration rate corresponding to the specified temperature and humidity. Thus, the target thickness can be calculated appropriately based on the restoration rate that varies depending on the environment.

(effect)
As described above, according to the second embodiment, when the temperature, humidity, and the like of the rolling environment are specified, the restoration rate that varies depending on the specified temperature, humidity, and the like is taken into consideration, and immediately after rolling by the rolling roller 20. Since the target thickness of the noodle band can be calculated, even if the temperature and humidity in the rolling environment fluctuate, the target thickness is calculated to an appropriate value according to the environment, and the roller moving part is calculated according to the calculated target thickness. The operation of 20c can be adjusted.
