Description

  The present invention relates to a noodle making machine, and more particularly to a noodle making machine capable of removing deposits attached to a rolling roller while reducing the occurrence of wear on the outer peripheral surface of the rolling roller and the deposit removing means.

In a noodle making machine, a dough formed by kneading wheat flour and water is rolled by a pair of rolling rollers to generate a strip-shaped noodle strip.
Here, when rolling a dough with a pair of rolling rollers, due to the characteristics of the dough, deposits such as the dough may adhere to the outer peripheral surface of each rolling roller.
And, if the deposit adheres to the outer peripheral surface of each rolling roller, the generated noodle strip is cracked, and the noodle strip generating operation is significantly hindered.
Therefore, in general, in a noodle making machine, a scraper (attachment removal means) formed of brass or the like is always brought into contact with the outer peripheral surface of each rolling roll to remove the adhering matter attached to the outer peripheral surface of each rolling roll. ing.
Conventionally, as this type of invention, for example, the one shown in FIG. 5 is known (see Patent Document 1).

And a pair of cutting blade rollers 130 and 140 for cutting n 'to generate noodle strings.
Further, the noodle making machine 100 is provided with a scraper 150 that varies the rotational speeds of the two rolling rollers 110 and 120 and always contacts the outer peripheral surface of the high-speed rolling roller 120.

In the noodle making machine 100, the rolling powder N and the generated noodle band N ′ are produced when the rolling powder N is rolled by the rollers 110 and 120 by changing the rotational speeds of the rolling rollers 110 and 120. It adheres only to the outer peripheral surface of the rolling roller 120 on the high speed side. Then, the dough N and the noodle strip N ′ adhering to the outer peripheral surface of the high-speed rolling roller 120 are peeled off from the outer peripheral surface of the rolling roller 120 by the scraper 150 that is always in contact with the outer peripheral surface of the rolling roller 120.
Thereby, according to the noodle making machine 100, it is not necessary to provide the scraper 150 in each of the rolling rollers 110 and 120, and the dough N and the noodle band N ′ adhere to the outer peripheral surfaces of the rolling rollers 110 and 120. This can be prevented.

  Each deposit removing roller 40 is formed by a roller having a smaller diameter than the rolling rollers 20a and 20b, and is disposed on the exit side of the noodle strip N of each rolling roller 20a and 20b. The dimension in the direction in which the rotating shaft of each deposit removing roller 40 extends (the depth direction in FIG. 1) is the same as the dimension in the extending direction of the rotating shaft of the corresponding rolling roller 20a, 20b. Further, each deposit removing roller 40 is arranged such that the rotation shafts A and B of the rolling rollers 20a and 20b corresponding to the rotation shaft of each deposit removing roller 40 are parallel to each other. Furthermore, the rotation direction c of each deposit removal roller 40 is the same as the rotation directions a and b of the corresponding rolling rollers 20a and 20b. Each deposit removing roller 40 is connected to the support shaft portion P via the arm portion 41, and can move between the deposit removing position α and the standby position β around the support shaft portion P. It is arranged like this. Here, when each deposit removing roller 40 is located at the deposit removing position α, the outer peripheral surface of each deposit removing roller 40 does not contact the outer peripheral surface of the corresponding rolling roller 20a, 20b. A slight gap is formed between the outer peripheral surface of each deposit removal roller 40 and the corresponding outer peripheral surface of the rolling rollers 20a, 20b.

  Each imaging means 50 is disposed on the exit side of the noodle band N of each rolling roller 20a, 20b. Each imaging means 50 is configured so as to be able to image the entire region in the direction in which the rotation axis of the outer peripheral surface of each rolling roller 20a, 20b extends. Here, in the deposit removing apparatus 30 according to the present embodiment, one imaging unit 50 is provided for each of the rolling rollers 20a and 20b, and each of the rolling rollers 20a and 20b is arranged by one imaging unit 50.

By moving one imaging means 50, it is possible to take an image of the entire area of the outer peripheral surface of each rolling roller 20a, 20b in the direction in which the rotation axis extends. As each imaging means 50, a CCD camera is used in the present embodiment. Each imaging unit 50 is connected to the determination unit 60, and the image data captured by each imaging unit 50 is transmitted to the determination unit 60.

As shown in FIG. 2, the determination unit 60 determines the presence of an attachment based on the storage unit 61 that stores the image data captured by each imaging unit 50 and the image data stored in the storage unit 61. The determination part 62 and the signal transmission part 63 which transmits an operation signal or a stop signal to the control means 70 based on determination of the determination part 62 are provided.
The control unit 70 rotates or stops each deposit removing roller 40 based on the operation signal or the stop signal transmitted from the signal transmission unit 63 of the determination unit 60, and sets each deposit removing roller 40 to the deposit removing position. Move to α or standby position β.

Next, the noodle making action of the noodle making machine 1 will be described.
When the noodle making operation of the noodle making machine 1 is started, first, raw material flour and water are kneaded in the kneading unit, and the dough M is generated. Then, the dough M generated in the kneading unit is sent to the rolling unit 10.
When the dough M is sent to the rolling unit 10, the dough M is rolled by the both rolling rollers 20 a and 20 b in the rolling unit 10, and the noodle band N is generated. And the noodle strip N produced | generated in the rolling part 10 is sent to a cutting part.
When the noodle band N is sent to the cutting part, the noodle band N is cut into a desired width and a desired length at the cutting part, and a noodle band is generated.

Next, the effect | action of the deposit | attachment removal apparatus 30 with which the rolling part 10 of the noodle making machine 1 is equipped is demonstrated.
In the attached matter removing apparatus 30 in the initial state, each attached matter removing roller 40 is positioned at the standby position β in a state where the rotation is stopped, and is in a standby state.
When the noodle making operation by the noodle making machine 1 is started, the deposit removing device 30 always images the entire area in the extending direction of the rotation axis of the outer peripheral surface of each of the rolling rollers 20a and 20b by each imaging device 50. In this case, the rolling rollers 20a and 20b rotate during the noodle making operation, so that the imaging devices 50 can sequentially capture the entire outer peripheral surface of the rolling rollers 20a and 20b.

Then, the image data captured by each imaging unit 50 is sequentially transmitted to the determination unit 60 and stored in the storage unit 61 of the determination unit 60. In this case, the image data transmitted by each imaging unit is stored in the storage unit 61 as a plurality of pixel data.
And the determination part 62 determines whether the deposit | attachment has adhered to the outer peripheral surface of each rolling roller 20a, 20b based on the pixel data of each rolling roller 20a, 20b stored in the memory | storage part 61. FIG. Each of the rolling rollers 20a and 20b is performed according to the following procedure.

As shown in FIG. 3, the determination unit 62 first sequentially reads out pixel data for one round of the outer peripheral surface of the rolling rollers 20a and 20b as one frame from the storage unit 61 (step S101). Perform the process.
Next, the determination unit 62 divides the read pixel data of each frame into a plurality of areas (step S102).
Then, the determination unit 62 calculates a difference between the pixel value of each pixel data in each area and a predetermined reference pixel value (step S103). Here, as the pixel value, at least one of hue, saturation, brightness, R value, G value, and B value can be selected and used. The reference pixel value refers to a pixel value determined in advance from pixel data obtained by imaging the outer peripheral surfaces of the rolling rollers 20a and 20b to which no deposit is attached by each imaging means 50.

Further, the determination unit 62 determines whether or not the difference calculated for each pixel data exceeds a predetermined threshold, and detects pixel data exceeding the threshold as detected pixel data (step S104). On the other hand, the determination unit 62 does not detect pixel data whose difference calculated for each pixel data does not exceed a predetermined threshold as detected pixel data.
Further, the determination unit 62 counts the number of detected pixel data detected in each area, and determines whether or not the counted number of detected pixel data exceeds a predetermined reference number for each area (step S105). ).

  And the determination part 62 determines with the adhering matter adhering to the outer peripheral surface of the rolling rollers 20a and 20b, when even one area where the detection pixel data number exceeds a reference number is detected, and control is carried out. An operation signal is transmitted to the means 70 (step S106). In this case, when a predetermined number of areas in which the number of detected pixel data exceeds the reference number is detected, it is determined that the deposit is attached to the outer peripheral surface of each of the rolling rollers 20a and 20b. It does not matter.

On the other hand, when no area where the number of detected pixel data exceeds the reference number is detected, the determination unit 62 determines that no deposit is attached to the outer peripheral surfaces of the rolling rollers 20a and 20b, and the control unit 70 A stop signal is transmitted to (step S107).
And when the control means 70 receives the operation signal from the signal transmission part 63 of the determination means 60, the deposit removal corresponding to the rolling rollers 20a and 20b determined to have deposits on the outer peripheral surface. After the rotation of the roller 40 is started, the deposit removing roller 40 is moved to the deposit removing position α, and the deposit removing roller 40 is put into an operating state.

  And the deposit removal roller 40 in an operating state is disposed through a slight gap between the outer peripheral surfaces of the rolling rollers 20a and 20b, and rotates at a high speed in the same direction as the rotation direction of the rolling rollers 20a and 20b. To do. Thereby, the adhering matter adhering to the outer peripheral surfaces of the rolling rollers 20 a and 20 b is removed by the air flow generated by the rotation of the adhering matter removing roller 40. Therefore, according to the deposit removing device 30 according to the present embodiment, the deposit adhered to the outer peripheral surfaces of the rolling rollers 20a and 20b without bringing the deposit removing roller 40 into contact with the outer peripheral surfaces of the rolling rollers 20a and 20b. Therefore, it is possible to prevent wear on the outer peripheral surfaces of the rolling rollers 20a and 20b and the outer peripheral surface of the deposit removing roller 40. In the present embodiment, the deposit removal roller 40 in the activated state employs a configuration in which a slight gap is provided between the outer peripheral surfaces of the rolling rollers 20a and 20b. However, the deposit removal roller 40 in the working state may be in contact with the outer peripheral surfaces of the rolling rollers 20a and 20b at all times or as necessary.

On the other hand, when the adhering matter removing roller 40 is in the operating state, the control unit 70 stops the rotation of the adhering matter removing roller 40 when receiving a stop signal from the signal transmitting unit 63 of the determining unit 60. The adhering matter removing roller 40 is moved to the standby position β, and the adhering matter removing roller 40 is set in the standby state.
Further, when the adhering matter removing roller 40 is in a standby state, the control unit 70 maintains the waiting state of the adhering matter removing roller 40 when a stop signal is received from the signal transmission unit 63 of the determining unit 60.

  As described above, in the noodle making machine 1 according to the present embodiment, when the determining unit 60 of the deposit removing device 30 determines that the deposit is attached to the outer peripheral surface of each of the rolling rollers 20a and 20b. Only the structure in which the corresponding deposit removing roller 40 operates is employed. Therefore, according to the noodle making machine 1 according to the present embodiment, it is possible to suppress the occurrence of wear on the outer peripheral surface of each rolling roller 20a, 20b and the outer peripheral surface of the deposit removing roller 40.

  Moreover, in the noodle making machine 1, the determination unit 62 calculates the difference between the pixel value of each pixel data of each frame read from the storage unit 61 and a predetermined reference pixel value, and performs rolling based on the calculation result. A configuration is adopted in which it is determined whether or not an adherent has adhered to the outer peripheral surfaces of the rollers 20a and 20b. Therefore, according to the noodle making machine 1, it is possible to accurately determine whether or not deposits are attached to the outer peripheral surfaces of the rolling rollers 20a and 20b.

Although the first embodiment of the present invention has been described above, various modifications can be made in this embodiment.
For example, the deposit removing device 30 according to the present embodiment employs a configuration using the deposit removing roller 40 as a deposit removing means for removing deposits attached to the outer peripheral surfaces of the rolling rollers 20a and 20b. Yes. However, the deposit removing device 30 may be configured to use a scraper as the deposit removing means. Also in this case, the tip of the scraper is attached to the outer circumference of the rolling rollers 20a and 20b only when the judgment means 60 of the deposit removing device 30 determines that the deposits are attached to the outer circumferential surfaces of the rolling rollers 20a and 20b. Touch the surface. Thereby, it becomes possible to suppress that abrasion arises in the outer peripheral surface of each rolling roller 20a, 20b and the front-end | tip part of a scraper.

Further, the deposit removing device 30 may be configured to use a belt conveyor as the deposit removing means. Also in this case, only when the determination means 60 of the deposit removing device 30 determines that deposits are attached to the outer peripheral surfaces of the rolling rollers 20a and 20b, the circulating surface of the belt conveyor is moved to the rolling rollers 20a and 20b. Contact the outer peripheral surface. Thereby, it becomes possible to suppress that abrasion arises in the outer peripheral surface of each rolling roller 20a, 20b and the circulation surface of a belt conveyor.
Furthermore, the deposit removing device 30 may be configured to use an air nozzle as the deposit removing means. Also in this case, high-pressure air is supplied from the air nozzle to the rolling rollers 20a and 20b only when the determining means 60 of the deposit removing device 30 determines that the deposits are attached to the outer peripheral surfaces of the rolling rollers 20a and 20b. Spray toward the outer surface.

  In addition, the determination unit 62 according to the present embodiment employs a configuration that determines whether or not the number of detected pixel data counted in each area exceeds a predetermined reference number for each area. Then, when even one area in which the number of detected pixel data exceeds the reference number is detected, it is determined that the deposit is attached to the outer peripheral surfaces of the rolling rollers 20a and 20b. However, the determination unit 62 may employ a configuration for determining whether or not the number of detected pixel data counted in each frame exceeds a predetermined reference number for each frame. In this case, when the number of detected pixel data exceeds the reference number, it is determined that the deposit is attached to the outer peripheral surfaces of the rolling rollers 20a and 20b.

  In addition, one of the rolling rollers 20a and 20b of the noodle making machine 1 is provided with a flange (not shown) on each end face in the direction in which the rotation shaft extends. Of the two rolling rollers 20a and 20b, the other rolling roller 20b is disposed between both flanges of the one rolling roller 20a. Thereby, each flange of one rolling roller 20a is in a state of covering each end surface of the other roller 20b. Therefore, in the noodle making machine 1, the dough M rolled by the both rolling rollers 20a and 20b is prevented from dropping from each end in the direction in which the rotation shafts of the both rolling rollers 20a and 20b extend. Here, when rolling the dough M by the both rolling rollers 20a and 20b, the dough M is put into the both rolling rollers 20a and 20b for a predetermined time, and the both rolling rollers reach the inner surface of each flange of the one rolling roller 20a. The noodle band N is generated only after the dough M is sufficiently filled between 20a and 20b. That is, the noodle band N is not generated immediately after the noodle making operation by the noodle making machine 1 is started and the dough M is put into the rolling rollers 20a and 20b. In this case, the dough M put into both the rolling rollers 20a and 20b is in a state of being easily attached to the outer peripheral surface of one of the rolling rollers 20a having a flange. When the dough M adheres to the outer peripheral surface of one of the rolling rollers 20a, it is naturally impossible to generate a normal noodle band N. On the other hand, once the noodle band N is generated and the generated noodle band N is sent to the cutting unit, the cutting unit pulls the noodle band N, so that the noodle band N generated by the rolling rollers 20a and 20b is It does not adhere to the outer peripheral surface of one rolling roller 20a. Therefore, the noodle making machine 1 may be configured such that each deposit removal roller 40 is in an operating state only for a predetermined time after the start of the noodle making operation. In this case, after the elapse of a predetermined time after the start of the noodle making operation, each deposit removing roller 40 is operated based on the determination by the determination means 60.

Next, a noodle making machine according to a second embodiment of the present invention will be described with reference to FIG.
FIG. 4 is a flowchart showing processing in the determination unit provided in the noodle making machine according to the second embodiment of the present invention.
The noodle making machine according to the second embodiment of the present invention includes a determination unit 82 (see FIG. 2) instead of the determination unit 62 in the noodle making machine 1 according to the first embodiment.
Based on the pixel data of each of the rolling rollers 20a and 20b stored in the storage unit 61, the determining unit 82 determines whether or not an adhering material is attached to the outer peripheral surface of each of the rolling rollers 20a and 20b. Each of the rolling rollers 20a and 20b is performed according to the following procedure.

As shown in FIG. 4, the determination unit 82 first sequentially reads out pixel data for one round of the outer peripheral surface of the rolling rollers 20 a and 20 b as one frame from the storage unit 61 (step S <b> 201). Perform the process.
Next, the determination unit 82 sets an address for each pixel data of each read frame (step S202).
The determination unit 82 divides the read pixel data of each frame into a plurality of areas (step S203).

  Then, the determination unit 82 calculates a difference between the pixel value of each pixel data of the currently read frame and the pixel value of each pixel data of the previously read frame (step S204). In this case, the calculation of the difference between the pixel value of each pixel data of the currently read frame and the pixel value of each pixel data of the previously read frame calculates the difference between the same addresses set in step S102. By doing. Here, as the pixel value, at least one of hue, saturation, brightness, R value, G value, and B value can be selected and used. The reference pixel value refers to a pixel value determined in advance from pixel data obtained by imaging the outer peripheral surfaces of the rolling rollers 20a and 20b to which no deposit is attached by each imaging means 50.

Further, the determination unit 82 determines whether or not the difference calculated for each pixel data exceeds a predetermined threshold, and detects pixel data exceeding the threshold as detected pixel data (step S205).
Further, the determination unit 82 counts the number of detected pixel data detected in each area, and determines whether or not the counted number of detected pixel data exceeds a predetermined reference number for each area (step S206). ).

And the determination part 82 determines with the deposit | attachment adhering to the outer peripheral surface of the rolling rollers 20a and 20b, when one area where the number of detected pixel data exceeds the reference number is detected, and control is performed. An operation signal is transmitted to the means 70 (step S207). In this case, when a predetermined number of areas in which the number of detected pixel data exceeds the reference number is detected, it is determined that the deposit is attached to the outer peripheral surface of each of the rolling rollers 20a and 20b. It does not matter.
On the other hand, when no area where the number of detected pixel data exceeds the reference number is detected, the determination unit 82 determines that no deposit is attached to the outer peripheral surface of the rolling rollers 20a and 20b, and the control unit 70 A stop signal is transmitted to (step S208).

  As described above, in the noodle making machine according to the present embodiment, the determination unit 82 calculates the difference between the pixel value of each pixel data of the currently read frame and the pixel value of each pixel data of the previously read frame. In addition, a configuration is adopted in which it is determined whether or not deposits are attached to the outer peripheral surfaces of the rolling rollers 20a and 20b based on the calculation result. Therefore, according to the noodle making machine according to the present embodiment, even when color unevenness occurs on the outer peripheral surface of each rolling roller 20a, 20b due to aging or the like, the outer peripheral surface of the rolling roller 20a, 20b adheres. It is possible to accurately determine whether or not the material adheres.

  The determination unit 82 according to the present embodiment employs a configuration that calculates a difference between the pixel value of each pixel data of the currently read frame and the pixel value of each pixel data of the previously read frame. However, the determination unit 82 stores the first read frame after the noodle making operation is started as a reference frame, and then sequentially reads the pixel value of each pixel data of each frame and the pixel value of each pixel data of the reference frame. The difference may be calculated. Also in this case, the difference between the pixel value of each pixel data of the sequentially read frame and the pixel value of each pixel data of the reference frame is calculated by calculating the difference between the same addresses set in step S102.
