However, in the wrinkle forming apparatus disclosed in Patent Document 1 and Patent Document 2, a plurality of wrinkle patterns are formed on the upper surface of the food to be covered with the wrinkle forming plate provided on the lower surface of the shutter piece at the same time as forming the food to be covered. For this reason, the outer skin material may be cut like a petal at the top of the final product obtained by steaming the encapsulated food, which may deteriorate the appearance. Further, in order to avoid this laceration, when the scissors forming plate is provided apart from the tip of the shutter piece, there is a problem that a substantially flat portion is formed on the top of the final product and the appearance is deteriorated.

Moreover, in the wrinkle forming apparatus disclosed in Patent Document 3, a small-diameter shaft that can be moved up and down and rotated is provided above the food material, and the small-diameter shaft touches the top of the food material and rotates, thereby twisting the wrinkle. Was molded. However, when the small-diameter shaft descends from above the food material and pushes down the food material, the height of the food material and the final product is deformed so that the food material has a flat impression. was there.

In addition, in the wrinkle forming apparatus disclosed in Patent Document 4, the wrinkle pattern is formed into a narrow groove shape according to the thickness of the wrinkle molded plate so as to press-fit the wrinkled plate into the food material, and further, the wrinkle molded plate is pushed down. In other words, there is a problem that the height of the food material is lowered because it is pressed into the food material. Therefore, two endless belts are provided on the upper surface of the food material conveyance path so as to rotate in opposite directions, and the food material on which the wrinkle pattern is formed is pinched by the belt while conveying the food material. It is provided with a shaping device that forms a spiral shape by twisting the peripheral portion of the pattern and shapes the height of the food material high. However, there is a problem that the press-fitted portion formed into a narrow groove shape is thin in the final product and the wrinkle pattern becomes unclear. Further, the shaping device has to be provided separately from the wrinkle forming device, and there is a problem that the whole device becomes complicated.

The present invention solves the above-mentioned problem. For example, when forming a plurality of ridges on the upper surface of a food material having a generally spherical upper portion such as a bun or bread, the top of the food material or the final product is formed. It is an object of the present invention to provide a wrinkle forming method and apparatus capable of preventing tearing, suppressing the deformation of food materials and final products to be low, and forming a wrinkle pattern with little bias.

The present invention has been made in view of the above-described problems, and the first invention includes a shutter in a wrinkle forming method for forming a plurality of wrinkles on an upper surface of a food material having a generally spherical upper portion. The food material is molded by a covering device, and the food material is placed on a cradle provided below the covering device, and then a plurality of straw molding plates are placed at the center of the food material at the placement position. A wrinkle forming method for a food material, characterized by moving in a horizontal direction so as to approach the side.

The second invention is a cocoon forming method for forming a plurality of wrinkles on an upper surface of a food material having a generally spherical upper portion, and a wrinkle forming plate for forming a plurality of wrinkles on the upper surface of the food material Are swung horizontally so as to approach toward the center side of the food material, and the surface dough of the food material is gathered along the inner side surface of the cocoon molding plate, and is further gathered by the adjacent cocoon molding plates. A method for forming a koji for a food material, wherein the kneaded material is raised so as to sandwich the surface dough so as to form a koji.

The third invention is a wrinkle forming apparatus for forming a plurality of wrinkles on an upper surface of a food material having a generally spherical upper portion, and a vertically movable covering device provided with a shutter for forming the food material And a cradle forming device fixed below the covering device, and a driving device for driving the opening / closing operation of the shutter of the covering device. A wrinkle forming device for a food material, characterized in that a drive device for reciprocating a wrinkle forming plate provided in the wrinkle forming device is provided, and a control device for controlling the drive of each drive device is provided.

According to a fourth aspect of the present invention, there is provided a wrinkle forming apparatus for forming a plurality of wrinkles on an upper surface of a food material having a substantially spherical upper portion, wherein a plurality of rotation shafts are suspended at equal intervals on a circumference on a base plate. A plurality of scissors forming members provided with scissors forming plates on the front end side so as to be swingable so that each rotation shaft is the center, and the scissors forming member is formed into a scissors toward the central axis of the circumference When the plate swings, the surface dough of the food material is gathered along the inner surface of the cocoon molding plate, and further, the surface dough gathered by the adjacent cocoon molding plates is raised to form the cocoon. It is a wrinkle forming device for a food material characterized by having a configuration.

According to the present invention, since the food material is encapsulated as in the prior art, the wrinkle pattern is not formed on the upper surface of the food material, but the wrinkle is formed on the encapsulated food material. It can suppress that the top part of a raw material or a final product tears.
In addition, it is not a conventional method that presses the bowl-forming plate down and press-fits it into the food material to form a ridge pattern on the upper surface of the food material. Since the wrinkle pattern is formed on the food material, it is possible to prevent the food material from being crushed and to prevent the food material from being deformed at a low height.
In addition, the food material is not transported and positioned after the food material is conveyed to the bag forming device provided at a position different from the covering device as in the prior art, and the food is formed below the covering device for forming the food material. Since the wrinkle is formed at the placement position without conveying the material, centering can be performed without separately providing positioning means, and a beautiful wrinkle pattern with little bias can be formed.
Furthermore, as in the past, the upper portion of the food material having a generally spherical shape is not formed with a groove pattern on the upper surface of the food material, so that a plurality of wrinkle forming plates approach the center side of the food material. By providing it so that it can swing in the horizontal direction, the surface dough of the food material is gathered along the inner surface of the bowl forming plate, and further, the food dough is sandwiched between the adjacent bowl forming plates to form the bowl pattern As a result, it is possible to effectively form the wrinkle pattern remaining on the upper surface of the food material and in the final product.

And the part which protruded the most center axis | shaft CL side of the blade edge | tip part 12b is provided linearly as the front-end | tip part 12a.

In the conventional wrinkle forming device, the wrinkle forming plate 12 gathers so as to be in contact with the central axis CL, so that the top of the final product is cut like a petal and the appearance may be deteriorated. Therefore, in this embodiment, when the scissors forming plate 12 is gathered near the central axis CL in order to prevent such a problem from occurring, the front end portion 12a of the scissors forming plate 12 coincides with the central axis CL. It is provided so as to be arranged slightly apart from the central axis CL. Referring to FIG. 2, the distance between the distal end portion 12 a of the scissors forming plate 12 provided in the scissors forming member 11 and the center of the rotation shaft 28 that is the center of rotation of the scissors forming member 11, that is, The swing radius RY is longer than the radius RB of the circumference S1 on which the rotation shaft 28 stands.

Further, the saddle forming plate 12 is located in the vicinity of a radial line RL that connects the center C with a rotation shaft 28 (a clockwise direction in FIG. 2) adjacent to the rotation shaft 28 to which the saddle forming plate 12 is attached. They are arranged almost in parallel. And the inner surface 12c of the eaves forming plate 12 forms a substantially dodecagonal space region around the central axis CL (see FIG. 6). In addition, the material of the cocoon molding plate 12 is appropriately selected from food dough, that is, a resin material such as polyacetal or high molecular weight polyethylene or aluminum having a surface coated with tetrafluoroethylene or the like in order to suppress adhesion to the skin material WA. it can.

As described above, the wrinkle forming apparatus 1 and the packaging machine 4 are controlled to be driven based on the data input to the control unit 9. The control method related to the baling machine 4 may be a known method, and a detailed description thereof is omitted here. For example, the implementation described in Japanese Patent No. 3471726 and Japanese Patent Application Laid-Open No. 2004-208524 already filed by the present applicant. Device based on form. The air cylinder 34 provided in the bag forming apparatus 1 is provided so as to control and drive a known electromagnetic valve.

Next, a process in which the wrinkle forming apparatus 1 forms a wrinkle pattern on the upper surface of the food material WE will be described with reference to FIGS. Each figure (a) is a top view, and each figure (b) is a front view. In each figure (a), only the bowl forming plate 12 and the food material WE are shown. In the present embodiment, as described above, the food material is attached so that the center axis CL of the koji forming apparatus 1 is substantially coincident with the center of the extrusion port 61 of the superposition nozzle 6 and the center of the opening 72 formed by the shutter 71. There is no need to separately provide a positioning means for the WE. In the state shown in FIGS. 4 to 7, the belt 81 is stopped.

First, FIG. 4 shows a state where the bowl forming plates 12 are separated from each other and surround the food material WE. At this time, the food material WE is covered and cut from the rod-like food WD pushed into the opening 72 by the closing operation of the shutter 71 provided in the covering and cutting unit 7, and placed on the cradle 83 via the transport belt 81. Placed. The enveloping / cutting unit 7 may be a known device, and is described in, for example, Japanese Patent Publication No. 5-53453, Japanese Patent Publication No. 5-43332, Japanese Patent No. 2729898, and Japanese Patent No. 3009140 which have already been filed by the present applicant. It is an apparatus based on the embodiment. Regardless of the number of scissors forming members 11, the shutter 71 can be cut and encased as long as it is three or more, but it should be composed of six to form a substantially circular shape when viewed from the top. Is preferred. In addition, in the process of FIG. 4 thru | or FIG. 7, the scissors forming apparatus 1, the covering cutting part 7, and the receiving stand 83 descend | fall synchronously, and the space | interval of the covering cutting part 7 and the receiving stand 83 is as needed. It is set up to spread gradually.

FIG. 5 shows that the shutter 71 starts the opening operation and moves so as to enlarge the opening 72, and the scissor forming plate 12 of the scissor forming device 1 starts swinging toward the central axis CL. A part of the blade edge portion 12b is in contact with the food material WE. The scissors forming plate 12 moves so that the cutting edge portion 12b is press-fitted into the food material WE, and the surface fabric of the food material WE is scraped and collected in the horizontal direction on the inner side surface 12c. The surface fabric scraped off by the ridge forming plate 12 gradually rises in a state along the inner side surface 12 c of the ridge forming plate 12.

FIG. 6 shows a state in which the ridge forming plates 12 are gathered near the central axis CL. The wrinkle forming plate 12 further swings in the horizontal direction from the state shown in FIG. 5, and the outer surface 12 d of the adjacent wrinkle forming plate 12 is formed by gathering the raised surface fabrics along the inner side surface 12 c of the wrinkle forming plate 12. Twelve wrinkle patterns are formed so as to be sandwiched between the two. Moreover, since the crushed plate 12 moves from the horizontal direction toward the central axis CL, the outer skin material WA is gathered toward the center, so that the top portion of the food material WE is deformed. Therefore, the food material WE is formed into a waist-high shape.

FIG. 7 shows a state in which the ridge forming plate 12 is separated from the vicinity of the central axis CL. As described above, the scissors forming plate 12 gathered in the vicinity of the central axis CL forms a substantially dodecagonal space region. Accordingly, the 12 folds are formed as radial convex portions that are continuous from the surface fabric sandwiched in the space region and are inclined with respect to the radial direction. And between the convex parts which adjoin, the concave part by which the surface fabric was shaved by the ridge forming board 12 is shape | molded.

After this, the scissor forming device 1 and the covering cutting part 7 rise and stand by upward. Further, the food material WE on which the ridge pattern is formed descends as the cradle 83 descends, and is then conveyed downstream (left side in FIG. 1) by the conveyor belt 81. And the cradle 83 also raises and returns to the state shown in FIG. By repeating these steps, a wrinkle pattern is continuously formed on the upper surface of the food material WE. The top of the food material WE has no laceration, and is further formed into a lofty food material.

Forming a beautiful wrinkle pattern with little deviation without misalignment of the food material with respect to the wrinkle forming apparatus 1 by forming the wrinkle on the upper surface of the food material WE without conveying the food material WE in this way. Can do. Further, the wrinkle pattern exhibits a clear raised portion. Furthermore, a wrinkle pattern remains clearly on the upper surface of the food material even after the fermentation process or the steaming process in the subsequent process.

The description of the scissor forming apparatus 1 according to the embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the claims. For example, the shape of the blade edge portion 12a of the bowl forming plate 12 is not limited to a convex curved shape, but may be a concave curved shape or a linear shape inclined downward toward the bending member 13 side. Furthermore, the ridge forming plate 12 may be a curved member instead of a flat plate. By changing these shapes, various ridge patterns can be formed. Moreover, you may change the attachment position of the ridge forming board 12, ie, the attachment angle with respect to the radial line RL. By this change, the movement trajectory of the koji forming plate 12 with respect to the food material WE is changed, and the manner of gathering the surface dough along the inner side surface 12c is changed, so that various wrinkle patterns can be formed.

Further, in the above embodiment, in order to prevent the top of the final product from opening like a petal, the swing radius RY of the flange forming plate 12 is set longer than the circumferential radius RB on which the flange forming members 11 are arranged, The tip 12a is provided so as not to coincide with the central axis CL. However, in order to prevent the top from opening like a petal, even if the swing radius RY is shorter than the circumferential radius RB, or the swing radius RY is equal to the circumferential radius RB. For example, by adjusting the screwing position of the rod end 36 screwed into the air cylinder 34, the rocking position of the rod forming member 11 is adjusted so that the rocking is stopped before the tip 12a reaches the center axis CL. Should be provided. Even in such a case, a beautiful wrinkle pattern can be formed on the upper surface of the food material WE, and the food material WE having a high waist can be formed.

Further, for example, in the above embodiment, the cocoon forming member 11 of the cocoon forming apparatus 1 is provided so as to be swingable. However, as shown in FIG. 8, the cocoon forming member 11 may be provided so as to reciprocate linearly. . (A) thru | or (c) is explanatory drawing which shows the process of forming a wrinkle pattern in the upper surface of the foodstuff raw material WE. The inner side surface 12 c of the ridge forming plate 12 is provided with a slight inclination with respect to the reciprocating track of the ridge forming member 11. Therefore, when the bowl forming plate 12 moves in the horizontal direction so as to approach each other toward the central axis CL, the upper surface of the food material can be raised along the inner side surface 12c. A beautiful wrinkle pattern can be formed on the upper surface of the raw material WE, and furthermore, a lofty food material WE can be formed.

In addition, the food to be encapsulated as the food material WE is not limited to the packaging machine 4 for continuously extruding the double-structured bar-shaped food covered with the inner packaging material with the outer skin material. Then, the food may be rolled up on a double-structured bar-shaped food, and the bar-shaped food may be suspended from the downstream end of the transport conveyor and supplied to the opening of the covering and cutting apparatus. In addition, the food package is not limited to a food package that is encapsulated and cut from the double-structured bar-shaped food product, but is a packaged food product that is formed by sealing the peripheral portion of the outer skin material so as to wrap the inner packaging material with a sheet-like outer skin material. It is also possible to prevent the opening of the top of the food material WE from being opened like a petal since the cocoon is formed after sealing the outer skin material.

Further, the food material WE may be a food such as bread dough formed only by the outer skin material WA that does not include the inner packaging material WB, and a beautiful wrinkle pattern can be formed on the upper surface of the food material.
