Description

  The present invention relates to an apparatus for producing a rice cake such as nigiri sushi or warship roll (a product obtained by shaping vinegared rice into a predetermined shape).

  Conventionally, in the earnest ball manufacturing apparatus provided with a quantification mechanism capable of quantifying the amount of the yield to be used for forming the yield, and a supply mechanism capable of supplying the yield to the quantification mechanism, the quantification mechanism includes: A roller group capable of adjusting the amount of the rice cake by pressurizing the rice cake, and a pair of feed rollers provided between the roller group and the supply mechanism and capable of feeding the rice cake supplied from the supply mechanism to the roller group Is known (see Non-Patent Document 1 below).

  In the conventional rice cake manufacturing apparatus, the density of the rice cake is controlled by measuring the current of the drive motor that rotates the pair of feed rollers and controlling the torque. More specifically, the current of the drive motor is measured to detect the load on the pair of feed rollers, and when the measured value reaches a set value, the drive motor is stopped and the rotation of the pair of feed rollers is stopped. As a result, it was possible to prevent an increase in the density of the ingredients fed into the roller group.

  However, in the conventional rice ball manufacturing apparatus, since the pair of feed rollers are fixed at a fixed position and do not move up and down, even if the measured value of the current of the drive motor is less than the set value, the measured value is relatively high. When the value is a value, the profit is pressurized between the pair of feed rollers and the roller group, and the density of the profit may be increased.

  In addition, in the conventional rice cake manufacturing device, the gap between the pair of feed rollers is much wider than the gap between the pair of lowermost rollers in the roller group, so the density of the peripheral portion of the rice cake fed into the roller group is controlled. Even if it was possible, it was difficult to control the density of the central part of the fry. In other words, when the density of the central part of the fry is high and the density of the peripheral part of the fry is low, the measured value of the drive motor current does not reach the set value, and the pair of feed rollers continue to rotate. This is because the nostalgia is sent to the group of rollers.

  Further, in this type of apparatus, the amount of the rice cake accumulated above the pair of feed rollers is detected, and when the amount does not satisfy the predetermined amount, the supply of the rice cake is stopped by the supply mechanism. Since the rotation of the feed roller and the roller group is not stopped, there is a problem in that the less than a certain amount is collected from the quantification mechanism.

Journal of the Japan Society of Mechanical Engineers, December 2008, Vol. 111, No. 1081, pages 952 to 953, “Sushi Robot-A Machine Using Artisan's Skill”

  An object of the present invention is to provide an apparatus for producing a building stone capable of producing a building stone having a uniform density and a low density (that is, having a large amount of voids).

In order to solve the above-mentioned problems, the present invention provides the following building-making apparatus.
1. A scouring ball manufacturing apparatus comprising a quantification mechanism capable of quantifying the amount of scouring to be used for forming a scouring bean, and a supply mechanism capable of supplying scouring to the quantification mechanism, wherein the quantification mechanism includes: A roller group capable of adjusting the amount of the rice by pressurizing the rice, and provided between the roller group and the supply mechanism so as to be movable up and down, and the food supplied from the supply mechanism can be sent to the roller group A pair of feed rollers and rotation of the pair of feed rollers are stopped when the pair of feed rollers are raised from the initial position, and the pair of feed rollers are rotated when the pair of feed rollers are returned to the initial position. And a first control means capable of resuming operation.
2. A second control means is provided that detects the amount of the deposit accumulated above the pair of feed rollers and can rotate the roller group and the pair of feed rollers only when the amount satisfies a predetermined amount. 2. The rice ball manufacturing apparatus according to 1 above.
3. The gap between the pair of feed rollers is narrower than the gap between the pair of rollers arranged at the lowermost stage in the roller group.
4). Any one of the above 1-3, wherein a first spring that urges the rotation shaft of the pair of feed rollers upward and a second spring that urges the rotation shaft downward are provided. 1.

According to the first aspect of the present invention, the pair of feed rollers is provided so as to be movable up and down, and the first control means can stop the rotation of the pair of feed rollers when the pair of feed rollers are raised from the initial position. Therefore, when the deposit is deposited over a certain amount between the pair of feed rollers and the roller group, the pair of feed rollers can be raised to suppress the pressurization of the deposit. Further, at this time, since the feed of the rice cake by the pair of feed rollers is also stopped, an increase in the density of the rice cake due to excessive accumulation of the rice cake can be prevented. In addition, since the first control unit can resume the rotation of the pair of feed rollers when the pair of feed rollers returns to the initial position, the amount of accumulated deposits between the pair of feed rollers and the roller group is reduced. As soon as the pair of feed rollers return to the initial position, the pair of feed rollers resumes rotation, and the feeding of the home by the pair of feed rollers is resumed. By such an action of the pair of feed rollers and the first control means, it is possible to prevent the deposits accumulated between the pair of feed rollers and the roller group from becoming overcrowded, thereby making the density uniform, In addition, it is possible to stably manufacture a rice ball having a low density (that is, having a large amount of voids).
According to the second aspect of the present invention, the amount of the deposit accumulated above the pair of feed rollers is detected, and the roller group and the pair of feed rollers can be rotated only when the amount satisfies a predetermined amount. Since the control means is provided, when the amount of the deposit accumulated above the pair of feed rollers does not satisfy the predetermined amount, the roller group and the pair of feed rollers do not rotate, and therefore there is the benefit in the quantification mechanism. Even so, since the profit remains in the quantification mechanism, it is possible to prevent the profit less than a certain amount from being discharged from the quantification mechanism.
According to the invention described in 3 above, since the gap between the pair of feed rollers is narrower than the gap between the pair of rollers arranged at the lowermost stage in the roller group, the benefit fed into the roller group is the same as in the prior art. It does not spread widely but concentrates on the central part. Therefore, it is possible to control not only the density of the peripheral portion of the rice cake fed into the roller group, but also the density of the central portion of the rice cake, so that more uniform and low density rice cake can be sent to the roller group. Become.
According to the invention described in item 4, since the first spring for biasing the rotation shafts of the pair of feed rollers upward is provided, a slight external force is applied to the pair of feed rollers from below. Even in such a case, the pair of feed rollers can rise against the weight of the beef existing above the pair of feed rollers and the weight of the pair of feed rollers. Therefore, it is possible to effectively suppress an increase in the density of the bean that exists between the pair of feed rollers and the roller group. Moreover, since the 2nd spring which urges | biases the rotating shaft of a pair of feed roller to the downward direction is provided, it is a pair which raised with the reduction | decrease of the amount of deposits of a beef between a pair of feed rollers and a roller group. The feed roller can be returned to the initial position.

  Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings.

  FIG. 1 is a schematic front view showing a configuration of a building ball manufacturing apparatus (hereinafter referred to as “the present apparatus”) according to an embodiment of the present invention, and FIG. 2 is a schematic side view showing the configuration of the apparatus. . As shown in these drawings, the present apparatus includes a quantification mechanism 100 that can quantify the amount of the bean paste used for forming the bean paste, a supply mechanism 200 that can supply the beneficiary to the quantification mechanism 100, and a quantification amount. And a forming mechanism 300 that can form the rice cake discharged from the forming mechanism 100 into a predetermined shape.

  The quantification mechanism 100 includes a group of rollers 101 to 104, a pair of feed rollers 105 and 106, and a first control unit. The roller groups 101 to 104 play a role of adjusting the amount (or size) of the building by pressurizing the building, and in this embodiment, a pair of upper rollers arranged with a predetermined interval. 101, 102, and a pair of lower rollers 103, 104, which are also arranged below the pair of upper rollers 101, 102 with a predetermined interval. Concavities and convexities are formed on the surface (outer peripheral surface) of each of the rollers 101 to 104 constituting the roller group, and these concavities and convexities can be fed downward while appropriately pressing the bedding. A cutter 107 is provided below the pair of lower rollers 103 and 104, and the beef discharged from the quantification mechanism 100 is cut into an almost equal size (or amount) by the cutter 107, thereby forming a molding mechanism. 300 is sent.

  The pair of feed rollers 105 and 106 plays a role of feeding the beneficiary supplied from the supply mechanism 200 to the roller groups 101 to 104. In this embodiment, the pair of upper rollers 101 and 102 in the roller group Between the supply mechanism 200, it is provided so that a vertical movement is possible. More specifically, the rollers 105 and 106 are installed so that the rotation shafts of the rollers 105 and 106 can slide in the vertical direction, so that the rollers 105 and 106 can move up and down. Thus, even when a slight external force is applied from below, the rollers 105 and 106 can rise against the weight of the bean paste above the rollers 105 and 106 and the own weight of the rollers 105 and 106. A first spring 108 that biases the rotating shaft upward is provided, and a second spring 109 that biases the rotating shaft downward is provided to return the raised rollers 105 and 106 to their initial positions. (See FIG. 2).

  Concavities and convexities are also formed on the surfaces (outer peripheral surfaces) of the pair of feed rollers 105 and 106, but the convex portions 105a and 106a extending along the thickness direction of the rollers 105 and 106 are adjacent to each other. Are arranged at wide intervals (see FIG. 1). In this embodiment, in each of the rollers 105 and 106, the interval between the convex portions is set to 45 degrees, and eight convex portions 105a and 106a are provided on the surfaces of the rollers 105 and 106, respectively. By doing so, there is an advantage that it is possible to reduce damage to the grain of the bean paste by the convex portions 105a and 106a when the beef is sent to the roller groups 101 to 104.

  The gap between the pair of feed rollers 105 and 106 is preferably narrower than the gap between the pair of rollers (in this embodiment, the pair of lower rollers 103 and 104) disposed at the lowermost stage in the roller group 101 to 104. . By doing so, it is possible to prevent the beneficiary sent to the roller groups 101 to 104 from spreading widely as in the prior art, and it is possible to concentrate the beneficiary sent to the roller groups 101 to 104 in the central portion (see FIG. 3). .

  More specifically, the gap between the pair of feed rollers 105 and 106, that is, the gap between the projections 105a and 106a when the projections 105a and 106a formed on the rollers 105 and 106 face each other, It is preferable that it is narrower than the gap between the pair of rollers (the pair of lower rollers 103 and 104) disposed at the lowermost stage in the roller group 101 to 104 and wider than the length in the length direction of the grain. When the gap between the pair of feed rollers 105 and 106 is narrower than the length of the staple grains, the convex grains 105a and 106a tend to damage the staple grains when feeding the staples to the roller groups 101 to 104. Because it becomes. In the present embodiment, since the length in the length direction of the grain is generally about 5 mm, the gap between the pair of feed rollers 105 and 106 is set to 5.4 mm.

  The first control means stops the rotation of the pair of feed rollers 105 and 106 when the pair of feed rollers 105 and 106 rises from the initial position, and the pair of the pair of feed rollers 105 and 106 returns to the initial position. The present embodiment plays a role of resuming the rotation of the feed rollers 105 and 106, and in this embodiment, includes a proximity sensor 110 and a control circuit (not shown). The proximity sensor 110 is installed behind the rotation shafts of the pair of feed rollers 105 and 106, and is turned on when the shaft 111 that moves up and down in conjunction with the rotation shafts of the pair of feed rollers 105 and 106 approaches the proximity sensor 110. The shaft 111 is set to an OFF state when the shaft 111 is separated from the proximity sensor 110 by a certain distance (see FIGS. 2 to 4). The control circuit energizes the drive motor 112 that rotates the rotation shafts of the pair of feed rollers 105 and 106 when the proximity sensor 110 is in the ON state, and releases the energization to the drive motor 112 when the proximity sensor 110 is in the OFF state. It is set to be.

  Therefore, according to this first control means, as shown in FIG. 3, when the pair of feed rollers 105 and 106 are in the initial position, the shaft 111 is close to the proximity sensor 110, so the proximity sensor 110 is The control circuit is turned on, and the control circuit energizes the drive motor 112 to rotate the pair of feed rollers 105 and 106. On the other hand, as shown in FIG. 4, when the pair of feed rollers 105 and 106 are lifted from the initial position, the shaft 111 is separated from the proximity sensor 110 by a certain distance, so the proximity sensor 110 is turned off and the control circuit is driven. Since energization to the motor 112 is released, the rotation of the pair of feed rollers 105 and 106 stops. When the pair of feed rollers 105 and 106 are lowered and returned to the initial position, the shaft 111 again approaches the proximity sensor 110 and the proximity sensor 110 is turned on, so that the control circuit energizes the drive motor 112. The rotation of the pair of feed rollers 105 and 106 is resumed. As a means for detecting the vertical movement of the pair of feed rollers 105 and 106, a mechanical switch such as a limit switch can be used instead of the proximity sensor 110.

  The supply mechanism 200 includes a first agitation blade 202 and a second agitation blade 203 that send the ingredients put into the hopper 201 downward while stirring. A photoelectric sensor 400 is installed in the vicinity of the discharge opening of the cover 204 that surrounds the passage of the stirrer that is stirred by the first stirring blade 202 and the second stirring blade 203. In the present embodiment, the photoelectric sensor 400 detects the amount of the deposits accumulated above the pair of feed rollers 105 and 106, but the detection means is not limited to the photoelectric sensor 400, and various object detections are possible. A sensor can be used. The photoelectric sensor 400 constitutes a part of the second control means, and the second control means includes a control circuit (not shown) in addition. The second control means detects the amount of the deposit accumulated above the pair of feed rollers 105 and 106, and only when the amount satisfies a predetermined amount, the roller groups 101 to 104 and the pair of feed rollers 105 and 106 are controlled. It plays the role of rotating. The photoelectric sensor 400 emits light, and is turned on when the light is blocked by the deposit accumulated above the pair of feed rollers 105 and 106, and is turned off otherwise. When the photoelectric sensor 400 is in the ON state, the control circuit energizes the drive motor 112 that rotates the rotation shafts of the pair of feed rollers 105 and 106 and the rollers 101 to 104 in the roller group, and the photoelectric sensor 400 is in the OFF state. In some cases, the drive motor 112 is set to be de-energized.

  Therefore, according to the second control means, when the amount of the rice cake accumulated above the pair of feed rollers 105 and 106 satisfies a predetermined amount, the light emitted from the photoelectric sensor 400 is blocked by the rice cake. 400 is turned on, and the control circuit energizes the drive motor 112 to rotate the pair of feed rollers 105 and 106 and the rollers 101 to 104 of the roller group. On the other hand, when the amount of the rice cake accumulated above the pair of feed rollers 105 and 106 does not satisfy the predetermined amount, the light emitted from the photoelectric sensor 400 is not blocked by the rice cake, so that the photoelectric sensor 400 is turned off and controlled. Since the circuit does not energize the drive motor 112, the pair of feed rollers 105, 106 and the rollers 101-104 of the roller group do not rotate. Therefore, even if there is a benefit in the quantification mechanism 100, the benefit remains in the quantification mechanism 100.

  The forming mechanism 300 includes a rotary table 301 having a large number of holes 301a slightly larger than the size of the bowl, and a pair of forming dies 302 and 303. Each time the rotating table 301 is discharged from the quantification mechanism 100 and cut by the cutter 107 is supplied into one hole 301a, the rotary table 301 is positioned at a certain angle so that another hole 301a is positioned under the cutter 107. It is designed to rotate. The pair of molding dies 302 and 303 includes a female die 302 that fits into a hole 301a formed in the rotary table 301 from below, and a male die 303 that fits into the hole 301a from above and presses the benefit existing in the hole 301a. It consists of. The rice cake is formed into a predetermined shape by the pair of forming molds 302 and 303.

  The present apparatus configured as described above operates as follows. That is, the rice cake 500 put into the hopper 201 is stirred by the first stirring blade 202 and the second stirring blade 203, loosened and moved downward in the cover 204 of the supply mechanism 200, and discharged from the cover 204. It is discharged from the outlet and accumulates above the pair of feed rollers 105 and 106. The photoelectric sensor 400 constituting the second control means detects the amount of the rice cake 500 accumulated above the pair of feed rollers 105 and 106, and is turned on only when the amount satisfies a predetermined amount. The control circuit constituting the means energizes the drive motor 112 of the pair of feed rollers 105 and 106 and the rollers 101 to 104 of the roller group, and the pair of feed rollers 105 and 106 and the rollers 101 to 104 of the roller group rotate. Start (see FIG. 3).

  On the other hand, since the photoelectric sensor 400 is in an OFF state and the control circuit does not energize the drive motor 112 when the amount of the deposit 500 accumulated above the pair of feed rollers 105 and 106 does not satisfy the predetermined amount, the pair of feed rollers 105 and 106 are not energized. The rotation of the rollers 105 and 106 and the rollers 101 to 104 of the roller group is not started. At this time, since the gap between the pair of feed rollers 105 and 106 is narrow, it is possible to prevent the deposit 500 from falling into the quantification mechanism 100 due to its own weight and being accumulated.

  After the rotation of the pair of feed rollers 105 and 106 and each of the rollers 101 to 104 in the roller group is started, the amount of the deposit 500 accumulated above the pair of feed rollers 105 and 106 does not satisfy the predetermined amount. Since the photoelectric sensor 400 is turned off and the control circuit releases the energization to the drive motor 112, the rotation of the pair of feed rollers 105 and 106 and the rollers 101 to 104 of the roller group is stopped. Therefore, even if the benefit 500 exists in the quantification mechanism 100, the benefit 500 remains in the quantification mechanism 100, so that the benefit 500 less than a certain amount is discharged from the quantification mechanism 100. Can be prevented.

  The rice cake 500 supplied from the supply mechanism 200 is sent to the roller groups 101 to 104 as the pair of feed rollers 105 and 106 rotate. In this embodiment, since the gap between the pair of feed rollers 105 and 106 is narrow, the garnish 500 fed into the roller groups 101 to 104 does not spread widely as in the conventional case, but concentrates in the central portion (FIG. 3). reference). Therefore, it is possible to control not only the density of the peripheral portion of the rice cake 500 fed to the roller groups 101 to 104 but also the density of the central portion of the rice cake 500, so that the rice cake with a more uniform density can be given to the roller groups 101 to 104. Can send.

  When the bean 500 is sent to the roller groups 101 to 104 by the pair of feed rollers 105 and 106, the bean 500 is deposited between the pair of feed rollers 105 and 106 and the pair of upper rollers 101 and 102 over a certain amount. Occasionally, the bean 500 is pressurized in the meantime, and the density of the bean 500 increases. In order to prevent this, in this embodiment, the pair of feed rollers 105 and 106 are provided so as to be movable up and down. In such a case, the pair of feed rollers 105 and 106 are raised to suppress pressurization of the foundation 500. (See FIG. 4). Further, when the pair of feed rollers 105 and 106 are raised, the proximity sensor 110 is turned off, and the control circuit constituting the first control means releases the energization to the drive motor 112. The feeding of the beef 500 by 106 is also stopped. Therefore, an increase in the density of the profit 500 due to excessive accumulation of the profit 500 can be prevented. Further, in this embodiment, since the first spring 108 that biases the rotation shafts of the pair of feed rollers 105 and 106 upward is provided, the pair of feed rollers 105 and 106 is slightly moved from below. Even when an external force is applied, the pair of feed rollers 105, 106 can rise against the weight of the foundation 500 existing above the pair of feed rollers 105, 106 and the weight of the pair of feed rollers 105, 106. Therefore, it is possible to more effectively suppress an increase in density of the bean 500 existing between the pair of feed rollers 105 and 106 and the pair of upper rollers 101 and 102.

  When the amount of deposit 500 between the pair of feed rollers 105 and 106 and the pair of upper rollers 101 and 102 decreases, the second spring 109 causes the pair of feed rollers to decrease as the amount of deposit 500 decreases. 105 and 106 descend and return to the initial position. As a result, the proximity sensor 110 is turned on, and the control circuit constituting the first control means resumes energization to the drive motor 112, so that the pair of feed rollers 105 and 106 immediately resumes rotation, and the pair of feed rollers The feeding of the bean 500 by 105 and 106 is resumed. By such an action of the pair of feed rollers 105 and 106 and the first control means, it is possible to prevent the deposit 500 deposited between the pair of feed rollers 105 and 106 and the pair of upper rollers 101 and 102 from being overcrowded. As a result, the low density rice cake 500 having a large amount of gaps can be stably fed to the roller groups 101 to 104.

  The roller groups 101 to 104 appropriately press the foundation 500 fed by the pair of feeding rollers 105 and 106 by the pair of upper rollers 101 and 102 and the pair of lower rollers 103 and 104, thereby increasing the size of the foundation 500. Arrange and quantify the beef 500. Thereafter, the rice cake 500 is discharged from the quantification mechanism 100, cut into a predetermined size by the cutter 107, and supplied to the hole 301 a of the rotary table 301 that constitutes the molding mechanism 300. Next, the molding mechanism 300 molds the bowl 500 with the pair of molds 302 and 303 to complete the bowl. Since the rice cake 500 formed by the pair of molds 302 and 303 has a uniform density, a large amount of voids, and a low density, the rice cake produced by this apparatus has a mouthpiece at the moment of biting. The texture is very good.
