Description

  The present invention relates to a die cutting device, and more particularly to a sheet dough die cutting device for punching a sheet dough with a die cutting roller and a sheet dough cutting method.

  Conventionally, in order to obtain a product dough having a predetermined shape by cutting a sheet dough, a belt conveyer is provided by a die cutting device including a belt conveyer for conveying the sheet dough and a die cutting roller provided facing the belt conveyor. A product dough having a predetermined shape is formed from the sheet dough by pressing a rotatable die-cutting roller against the sheet dough being conveyed. In addition, the sheet dough sorts product dough that has been die-cut into a predetermined shape and die-cut waste after die-cutting the product dough, and the die-cut waste is mixed with the raw material in the process before being die-cut. Then, it is rolled again and conveyed as a sheet dough to a die cutting roller by a belt conveyor.

  However, in the above-described die cutting device, the die cut sheet do not peel off from the die cutting roller, which may result in die cutting failure.

In order to solve such problems, as a die cutting device for die cutting a sheet dough, a belt conveyor for conveying the sheet dough, a die cutting roller provided facing the belt conveyor, and a cover for the die cutting roller are provided. In addition, a confectionery die-cutting device in which a heater for removing the mold is attached to the inside of the cover is disclosed (for example, Patent Document 1). According to this confectionery die-cutting device, since the die-cutting roller is heated, it is possible to obtain an excellent effect that it can be smoothly peeled and removed without damaging the dough.
Japanese Utility Model Publication No. 63-201482

  However, the die cutting device for confectionery according to Patent Document 1 described above is kneaded with flour, water, milk, egg, sugar, salt, spices, etc., and applied to confectionery sheet dough such as pie, cookies or cakes, There is a concern that the sheet material may not be peeled off from the mold release roller when it is applied to a sheet material made of a different material because it does not use a release material.

  For example, to produce rice crackers made from glutinous rice or glutinous rice with a die-cutting device, add a suitable amount of water to rice or starch, which is the main ingredient, and knead or boil it. The raw material is rolled to form a sheet dough, and the sheet dough is die-cut into a predetermined shape by a die-cutting roller. In this case, the temperature of the dough-like sheet fabric before molding is about 45 ° C. to 70 ° C., contains about 50% of moisture, is highly flexible at high temperatures, and has a specific stickiness. When the die is drawn by the die-cutting roller, the sheet dough is sticky and is not die-cut, and even if the sheet dough is die-cut, the sheet dough is wound around the die-cutting roller to obtain the prescribed shape. There was a problem that it was difficult.

  In order to deal with such problems, in the case of punching a sheet material that has been made into a bowl, conventionally, a release material made of oil or the like is applied to the mold release roller by a release material supply roller, and the sheet fabric is removed from the mold release roller. It is made to peel from.

  However, in order to perform the die-cutting operation continuously, it is necessary to replenish the release material supply roller by brushing or the like, so that the replenishment work is complicated.

  Further, when liquid oil or fat is used as the mold release material, the oil or oil is likely to flow down from the die-rolling roller, and as a result, there is a problem that the efficiency is poor due to scattering on the fabric. For this reason, a solid oil that adheres firmly to the mold release roller is used as the release material. However, since solid oils and fats have different peelability depending on the temperature, there is a problem that it is necessary to control the melting point of the fats and oils by changing the blending of fats and oils according to the temperature change in order to obtain predetermined peelability.

  Further, the release material applied to the die-cutting roller adheres to the product dough when the die-cutting blade contacts the product dough when the sheet dough is die-cut. The mold release material adhered to the product dough prevents the proper water from being scattered from the product dough, resulting in unstable rice cracker shape, and uneven baking and seasoned honey adhesion. Further, there was a problem that the quality of rice crackers produced from the product dough deteriorated due to deterioration due to oxidation of the release material.

  At the same time, the mold release blade comes into contact with the die-cutting scraps remaining after the product dough is die-cut from the sheet dough, so that the release material adheres to the die-cutting scraps. This die cutting waste is returned to the step before rolling, mixed with the newly kneaded raw material, rolled again, and supplied as sheet dough to the die cutting roller. Therefore, a series of operations in which the release material adheres to the die-cutting scrap every time it passes through the die-cutting roller, and the die-cutting scrap to which the release material adheres is returned to the pre-rolling process and mixed with the newly crushed raw material By repeating the above, the content of the release material in the sheet fabric increases. In this way, the quality of the rice crackers described above is further deteriorated.

  In particular, when the outside air temperature is low, the solid fat as a release material is difficult to dissolve, so that the releasability tends to decrease, and by increasing the amount of the release material used to obtain a predetermined releasability, There was a vicious cycle in which the content of the release material in the sheet dough increased and the quality of rice crackers deteriorated.

  In addition, the release material attached to the product dough may cause contamination of the equipment in subsequent processes such as drying and baking, and is unsanitary. Leading to deterioration. Therefore, in order to prevent such a secondary release material from adhering to the product fabric, a great deal of time and labor must be split in the hygiene management of the equipment, leading to deterioration in workability and productivity. .

(1) Overall Configuration A preferred embodiment of the present invention will be described below with reference to the drawings. The die cutting device 1 shown in FIG. 1 is configured to perform a series of die cutting operations on the sheet material 3 supplied from the sheet material supply means 2 as a whole.

  The die cutting device 1 of the present invention includes a sheet dough supply unit 2 for supplying a sheet dough 3, a die cutting roller 4, and a heater 5 as a heating unit, and the sheet dough supplied by the sheet dough supply unit 2. 3 can be punched into a predetermined shape.

  The sheet dough supply means 2 is provided on the upstream side of the base 6 and includes a rolling device 7 and a belt conveyor 8 as a conveying device. As a result, the sheet material supply means 2 is configured to roll the raw material 9 that has been made into a bowl to form a sheet material 3 having a predetermined thickness and to supply the sheet material 3 to the die cutting roller 4.

  The rolling device 7 is composed of a raw material supply unit 10 and a pair of rolling rollers 11. A raw material 9, which has been kneaded by adding an appropriate amount of water to rice or starch and then kneading or boiled, is used as a raw material. The sheet material 3 is continuously formed by being supplied from the supply unit 10 between the pair of rolling rollers 11 and rotating the rolling roller 11. The sheet material 3 formed by the rolling roller 11 is supplied onto the belt conveyor 8.

  The belt conveyor 8 is installed on the upper side of the base 6 and includes a driving shaft 12, a driven shaft 13, and a belt 14 hung between the driving shaft 12 and the driven shaft 13. In the belt conveyor 8, the belt 14 and the driven shaft 13 are rotated by the driving shaft 12 rotating by a rotational force applied from a driving motor (not shown). Thereby, it is comprised so that the sheet | seat material | dough 3 can be poured from the upstream of the longitudinal direction of the base 6 to the downstream.

  As shown in FIG. 2, the die-cutting roller 4 has a long cylindrical shape, is laid downstream in the width direction of the belt 14 on the downstream side of the rolling device 7, and is attached to the base 6 via the roller support portion 20. It is supported rotatably. The die cutting roller 4 is pressed against the belt 14 by a roller support portion 20. In this way, the die-cutting roller 4 is rotated by the progress of the belt 14 due to the frictional force generated between the surface of the belt 14. Thereby, the die cutting apparatus 1 can improve the die cutting. On the surface of the die-cutting roller 4, a plurality of die-cutting blades 21 having a predetermined shape, for example, circular die-cutting blades 21 in the present embodiment are provided. The die cutting blade 21 is formed such that the height at which the cutting edge of the die cutting blade 21 protrudes from the surface of the die cutting roll is higher than the thickness of the sheet material 3. In this manner, the die cutting roller 4 is configured so that the die cutting blade 21 can rotate while maintaining the same rotational speed as the traveling speed of the belt 14 while contacting the surface of the belt 14. In addition, a lower mold roller 22 is provided below the mold release roller 4 via a belt 14 and is configured to rotate as the belt 14 advances.

  Further, the mold release roller 4 is supplied with solid fat as a release material from a release material supply roller 23 as a release material supply means. The release material supply roller 23 is provided with a brush on the surface, and is installed above the die-cutting roller 4 and in parallel with the die-cutting roller 4. Further, the release material supply roller 23 is rotatably supported by the base 6 via the roller support portion 20 so that the surface thereof can come into contact with the surface of the mold release roller 4. In this way, the release material supply roller 23 is configured to be able to rotate together with the mold release roller 4 by the frictional force generated by contacting the mold release roller 4 on the surface. Incidentally, various solid fats and oils can be applied. For example, those having the constituent elements, constituent ratios, and characteristics shown in Tables 1 and 2 are preferable.

  The heater 5 is configured to heat the surface of the die cutting roller 4, particularly the die cutting blade 21 from the upstream side of the die cutting roller 4. The heater 5 includes a sheathed heater 24 and a reflector 25, and is installed on the base 6 with a heater support member 26 and is electrically connected to a power source (not shown). Incidentally, the sheathed heater 24 is subjected to a special surface treatment, and is formed so as to increase the heat energy radiation efficiency and emit far infrared rays.

  A temperature sensor 27 for measuring the surface temperature of the die-rolling roller 4 is installed on the base 6. The temperature sensor 27 is provided on a sensor support portion 28 that is provided on the downstream side of the die-cutting roller 4 and is horizontally mounted in the width direction of the base 6. The heater 5 is configured to heat the surface of the die-rolling roller 4 to a predetermined temperature via a control unit (not shown) based on the temperature measured by the temperature sensor 27. In addition, in order to improve the peelability of the sheet | seat material | dough 3, it is preferable to heat the die cutting roller 4 to 30 degreeC or more, and it is preferable to make it the sheet | seat material temperature or less.

  Further, as shown in FIG. 1, on the upstream side of the release material supply roller 23, the release material supply roller 23 rotates, so that the solid oil applied to the release material supply roller 23 is uncut. A protective plate 30 is provided that prevents the material 3 and the heater 5 from scattering and protects the release material supply roller 23 from the heat of the heater 5. Further, the die cut sheet dough 3 is separated into product dough 3a and die cutting waste 3b, and the product dough 3a proceeds to subsequent processes such as drying and baking. It returns to and is mixed with the raw material 9.

(2) Operation and Effect In the above configuration, the sheet dough supply means 2 rolls the raw material 9 that has been made into a bowl shape with the rolling device 7 and supplies it to the belt conveyor 8. The belt conveyor 8 supplies the sheet dough 3 to the die-cutting roller 4 by placing the sheet dough 3 supplied from the rolling device 7 on the belt 14 and sending it from the upstream side to the downstream side.

  Further, the die cutting roller 4 is supplied with the solid fat from the release material supply roller 23, and the die cutting roller 4 is rotated in the same manner as the belt conveyor 8 while the die cutting blade 21 is heated to a predetermined temperature by the heater 5. It rotates at the speed and in the reverse direction of the rotation direction of the belt conveyor 8.

  Then, the sheet dough 3 passes through the contact portion between the belt 14 and the die cutting roller 4 so that the die cutting blade 21 is pressed against the sheet dough 3 and the sheet dough 3 is die-cut into a predetermined shape (in this case, circular). To do. At this time, the lower mold roller 22 is provided below the mold release roller 4 via the belt 14, so that the load can be reliably transmitted from the mold release roller 4 to the sheet material 3.

  In this way, in the die cutting device 1, when the die cutting roller 4 is heated to a predetermined temperature, after the die cutting, the die cutting blade 21 moves away from the sheet material 3 as the die cutting roller 4 rotates. The sheet material 3 can be smoothly separated from the die cutting blade 21 to form a desired product material 3a.

  Therefore, in the die cutting device 1, since the amount of solid oil / fat applied can be suppressed, the work of supplying the solid oil / fat to the release material supply roller 23 can be reduced.

  Furthermore, in the die cutting device 1, the solid fat applied to the die cutting roller 4 can be reduced, so that the solid fat adheres to the product dough 3a and the die cutting waste 3b from the die drawing roller 4 as in the past. It is possible to suppress the deterioration of the quality of 3a and improve the quality of the rice cracker as the final product.

  Moreover, as shown in Table 3, in the die-cutting device 1, by providing the heater 5, compared to the case without the heater, there is a variation for each product, but the amount of solid fat used is reduced by 20% or more. I found out that Therefore, it is possible to reduce the amount of solid fats and oils adhering to the sheet dough 3 and to prevent the quality of the product dough 3a from being deteriorated, to prevent the equipment from being soiled and to improve workability and productivity.

  Table 4 shows the results of measuring the application frequency of solid fats and oils in a die cutting apparatus provided with a heater.

  Table 5 shows the results of measuring the application frequency of solid fats and oils in a die cutting apparatus without a heater.

  As shown in Tables 4 and 5, it was found that in the die-cutting device 1, by providing the heater 5, the application frequency of solid fats and oils can be doubled as compared with the case without the heater. Therefore, it is not necessary to frequently supply solid fat to the release material supply roller 23 as in the conventional case, and workability can be improved.

  Further, in the die cutting device 1, the heater 5 is provided on the upstream side of the die cutting roller 4 so that the die cutting blade 21 is heated just before the die cutting blade 21 contacts the sheet material 3. . Therefore, the die cutting blade 21 can be efficiently heated.

  Furthermore, in the die cutting apparatus 1, the heater 5 is formed so as to be able to radiate far infrared rays, and is configured such that the radiation can be reflected to the die cutting roller 4 by the reflecting plate 25. The die cutting blade 21 can be heated.

  Therefore, the die cutting device 1 can reliably release the sheet dough 3 from the die cutting roller 4 by heating the die cutting blade 21 and dissolving the solid fat applied to the die cutting blade 21.

  Moreover, the die cutting device 1 can adjust the cutting edge temperature of the die cutting blade 21 in accordance with the melting point of the solid fat used by providing the temperature sensor 27. Therefore, in the die-cutting device 1, it is possible to perform die-cutting while dissolving only necessary solid fats and oils, thereby suppressing the amount of solid fats and oils and preventing deterioration of quality.

  Further, in a series of die-cutting operations, the temperature sensor 27 is used to maintain the blade tip temperature of the die-cutting blade 21 at a predetermined temperature that is 30 ° C. or more and lower than the sheet material temperature. Therefore, in the die cutting device 1, the sheet dough 3 is stably removed from the die cutting roller 4 by performing a die cutting operation while dissolving only the solid oil necessary for peeling the sheet dough 3 from the die cutting roller 4. While being able to peel, the solid fats and oils adhering to the sheet | seat material | dough 3 can be suppressed to the minimum, and deterioration of quality can be prevented.

  Further, in the die cutting device 1, by providing the protection plate 30, it is possible to prevent the solid fat from scattering from the release material supply roller 23 to the sheet fabric 3 before being punched. It is possible to prevent the content of the solid fat from increasing, and to prevent the quality of the product dough 3a from deteriorating. Moreover, in the die cutting apparatus 1, since the protection plate 30 is provided, the release material supply roller 23 is protected from the heat of the heater 5, and therefore the deterioration of the release material supply roller 23 can be prevented.

  As described above, in the present embodiment, in the die cutting device 1, the sheet dough supply unit 2 that supplies the sheet dough 3 and the sheet dough 3 supplied by the sheet dough supply unit 2 are punched into a predetermined shape. And a release material supply means for supplying a release material to the mold release roller 4, and a heating means for heating the mold release roller 4. Can be reliably released from the mold.

  In the die cutting apparatus 1, the heating means can stably release the sheet material 3 from the die cutting roller 4 by heating the die cutting roller 4 to 30 ° C. or higher.

  In the die cutting method, a sheet dough 3 supplying step for supplying the sheet dough 3, a die cutting step for punching the supplied sheet dough 3 with a die cutting roller 4, and a release material for the die cutting roller 4 are used. A release material supply step for supplying, and a heating step for heating the mold release roller 4, whereby the sheet material 3 can be reliably released from the mold release roller 4.

  Moreover, in the die cutting method in this embodiment, the heating step can stably release the sheet material 3 from the die cutting roller 4 by heating the die cutting roller 4 to 30 ° C. or higher.

  The present invention is not limited to this embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, the die cutting device 1 has been described with respect to the case where the heater 5 is installed on the upstream side of the die cutting roller 4. However, the present invention is not limited to this, and if the die cutting blade 21 can be heated to a predetermined temperature, the die cutting device 1 A heater 5 may be built in the roller 4. Moreover, although the heater 5 demonstrated what can radiate | emit far infrared rays, this invention is not limited to this, The normal sheathed heater 24 which has not performed special surface treatment may be sufficient. Further, the die cutting blade 21 has been described as having a circular shape, but the present invention is not limited to this, and can be applied to various shapes. For example, as shown in FIG. The release material supply roller 23 has been described with respect to the case where the surface thereof is in contact with the surface of the mold release roller 4 and rotates together with the mold release roller 4 due to the frictional force generated on the contact surface. It is good also as rotating by the drive force by a drive motor.
