The bell crank 31 is pivotally supported by a notch portion of the pivot support 32 and is swingable so as to reciprocate along the direction in which the brazing plate 30 is radially arranged. A rod 34 of an air cylinder 33 disposed above is inserted into the shaft support 32. Although not shown, one end of the bell crank 31 is locked to the tip of the rod 34. Therefore, when the rod 34 moves up and down, the bell crank 31 swings all at once, and the brazing plate 30 reciprocates all at once so as to gather toward the center and disperse outward. become. As the wrinkle pattern imparting means, a known device described in the above-mentioned patent document can be used in addition to the above-described brazing device 3.

  In the rotating device 4, a conical press-fit body 42 is fixed to the lower end of a rotating shaft 41 that is rotationally driven by a motor 40. The entire rotating device 4 is moved up and down by moving means (not shown). A stopper 43 is installed adjacent to the rotating device 4 so that the central portion of the food F is positioned at the lowered position of the press-fit body 42. As shown in FIG. 2, the stopper 43 has a shape bent in a dogleg shape, and the conveyed food F is positioned by contacting both the bent two sides of the stopper 43. The stopper 43 is fixed to the rod of the air cylinder 44 disposed above and moves up and down, and moves the stopper 43 upward when the food F is conveyed to the next shaping step. In order to efficiently twist the press-fitting surface of the press-fit body 42 to the food F, it is preferable to form irregularities. For example, as shown in FIG. 3, a notch 43 is formed at the tip (FIG. 3A), or a plurality of protrusions 44 and 45 are provided at predetermined intervals (FIGS. 3B and 3C). ) Or a spiral linear protrusion 46 may be formed (FIG. 3D).

  An air cylinder may be used as a driving source of the rotating device 4. If the rod is rotated while moving up and down, the rotating device 4 does not need to be moved up and down by the moving means.

  The belt shaping device 5 includes a pair of endless belts 50 and 51. The endless belt 50 is stretched around the driving roller 52 and the driven roller 53, and the endless belt 51 is stretched around the driving roller 54 and the driven roller 55. The driving roller 52 and the driving roller 54 are rotationally driven by a motor (not shown), and the endless belts 50 and 51 are conveyed. The mutually opposing surfaces of the endless belts 50 and 51 are set to be parallel, and the food F is conveyed and shaped while being sandwiched between the opposing surfaces. The endless belt 51, the driving roller 54, and the driven roller 55 are attached to a frame body, and all of them are movable so as to approach or separate in the direction of the endless belt 50. The interval between the two can be adjusted according to the size of the food F.

As shown in FIG. 4, the endless belt 50 has the same conveying direction as the conveying direction of the food F with respect to the conveying speed V ₁ of the food F by the belt conveyor, and the conveying speed V ₂ is based on the conveying speed V ₁ . It is adjusted to be larger. Further, the endless belt 51 is conveying direction of the opposing surface thereof conveyance speed V ₃ in the conveying direction and opposite direction of the food F is adjusted to the same size as the conveying speed V _2. Therefore, when the food F is conveyed between the pair of endless belts 50 and 51, the food F is rotated counterclockwise while being pinched between the opposed surfaces of the belt, so that the periphery of the food F is twisted. Become. In addition, what is necessary is just to adjust the conveyance speed of an endless belt suitably, seeing the finishing condition of the shaping of the food F.

  As shown in FIG. 5, a protrusion 56 is formed in the center portion along the circumferential direction on the inner periphery of the endless belt 50, and a groove that fits the protrusion 56 in the driving roller 52 and the driven roller 53. 57 is provided along the circumferential direction. Similarly, a protrusion 58 is formed on the inner circumference of the endless belt 51, and a groove 59 that fits the protrusion 58 is provided in the drive roller 54 and the driven roller 55. When the protrusion and the groove are fitted and the endless belt rotates, it is possible to prevent the belt from being displaced from the roller and coming into contact with the lower belt conveyor. In addition, since the protrusion is pressed against the food F, a pressing force can be effectively applied to the food F, and shaping can be performed efficiently.

  In the belt shaping device described above, a pair of endless belts is used, but one endless belt can be replaced by a plate-like body. As shown in FIG. 6, when the plate-like body 70 having the same width as the endless belt 50 is disposed so as to face the endless belt 50, the transport speed of the endless belt 50 is made larger than the transport speed of the belt conveyor. F rotates counterclockwise.

  In the belt conveyors 6a to 6d, the conveyance belts are driven by drive motors 60a to 60d, respectively. In addition, tension rollers 61a to 61d are wound around each conveyor belt so that appropriate tension is applied to the conveyor belt. An optical sensor 62 is disposed at the downstream end of the belt conveyor 6a. When the optical sensor 62 detects that the food F has been conveyed to the downstream end, the belt conveyor 6a is temporarily stopped. And timing adjustment with the process process of the brazing apparatus 3 is performed, the belt conveyor 6a is conveyed again, and the foodstuff F is transferred to the belt conveyor 6b. An optical sensor 63 is also arranged at the downstream end of the belt conveyor 6b. When the optical sensor 63 detects the food F, the belt conveyor 6b is temporarily stopped, and similarly the timing of the processing process of the rotating device 4 is detected. After adjustment, the food F is transferred from the belt conveyor 6b to the belt conveyor 6c. The food F processed in the rotating device 4 is transferred from the belt conveyor 6c to the belt conveyor 6d and conveyed to the belt shaping device 5.

  Next, the operation of the above-described embodiment will be described. FIGS. 7 to 11 are plan views (FIG. 7 (a) to FIG. 11 (a)) and side views (FIG. 7 (b) to FIG. This is shown in FIG.

  The food F shown in FIG. 7 is formed into a steamed shape by wrapping a predetermined amount of inner material with a skin material by a conventionally known molding apparatus. Next, the food F is conveyed to the center position of the brazing plate 30 of the brazing apparatus 3, and the brazing plate 30 is swung toward the center all at once to press-fit into the food F, as shown in FIG. A wrinkle pattern is formed on the surface of the food F by the radial grooves p. At that time, the outer skin material of the food F is gathered toward the center and formed into a conical shape.

  Next, the food F is conveyed to the rotating device 4 and positioned by the stopper 43, and the press-fit body 41 is lowered and press-fitted into the center position of the ridge pattern as shown in FIG. The conical shape formed on the top of the food F by the press-fitting of the press-fit body 41 is crushed, and the height of the food F as a whole is also reduced. Then, as shown in FIG. 10, when the press-fit body 41 is rotated clockwise in the press-fit state, the inner portion of the groove p is deformed in a spiral shape by being dragged by the movement of the press-fit body 41 at the central portion of the ridge pattern. . When the press-fit body 41 is rotated by a predetermined angle, the press-fit body 41 stops rotating and rises. A depression h is formed in the trace of the press-fit body 41 rising.

  Next, the food F is transferred to the belt shaping device 5 and rotates while the periphery of the food F is pinched by the endless belts 50 and 51. When rotating, the outer shell material of the food F is twisted so as to be pulled by the endless belt. That is, since the endless belts on both sides move in the opposite directions, only the outer skin material of the portion where the endless belt is in pressure contact is pulled in the opposite direction and acts as if twisted from the whole. Since the rotation direction of the food F rotates counterclockwise opposite to the rotation direction of the press-fit body 41, the peripheral portion of the ridge pattern is deformed so as to be pulled counterclockwise, and the outer portion of the groove p is anti-clockwise. The entire groove p flows in a clockwise direction and has a spiral shape that is greatly curved from the periphery of the food F toward the top. And the groove | channel p is also extended around the foodstuff F, and is formed longer.

12 shows a cross-sectional view of the groove p, and bulges m ₁ and m ₂ having substantially the same shape are formed on both sides of the groove p formed by the brazing device 3 (FIG. 12 ( a)), the outer portion of the groove p by the surrounding food F by the belt shaping device 5 is pulled, one of the upsurge m ₂ is adapted to bend larger than the other upsurge m _1, The leopard pattern becomes more emphasized.

  Since the food F is pinched by the endless belt, the food F is swollen up as a whole, so that the food F has a high waist, and the overall height of the food F that has been lowered by the rotating device 4 is also increased. The

  As described above, the food F can be finished in a shape closer to a handmade style, with a spiral ridge pattern clearly formed and a depression formed at the top.
