The best mode for carrying out the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 4, the rice ball forming machine according to the present invention is disposed so as to be able to be turned up and down by an operating lever 3 provided on a support frame 2 on one end side on a support base 1. The upper forming mold 4 for forming a portion and the lower forming mold 5 for forming the other side surface of the rice ball are arranged on the other end side of the support base 1 to form a pressing die. Then, a predetermined amount of cooked rice P is accommodated in the lower forming mold 5 and the upper forming mold 4 is fitted into the lower forming mold 5 by tilting the operation lever 3. The rice P is pressed by the upper forming mold 4 to form a rice ball having a predetermined shape.

  As shown in FIG. 4, the lower forming mold 5 is composed of a first rice ball forming hole 5a having a substantially triangular shape in plan view and a second rice ball forming hole 5b having a substantially triangular shape in plan view. One side surface of the formation hole 5a and one side surface of the second rice ball formation hole 5b are communicated with each other via the partition portion 5c. On the other hand, as shown in FIG. 2, the upper forming mold 4 is composed of a first upper forming mold 4a having a substantially triangular shape in a plan view and a second upper forming mold 4b having a substantially triangular shape in a plan view. Then, one side surface of the first upper forming mold 4a and one side surface of the second upper forming mold 4b are connected to each other via a dividing plate 4c protruding downward to form the first rice ball. When inserted into the hole 5a and the second rice ball forming hole 5b, the partition portion 5c and the dividing plate 4c are joined to form one side surface portion of the rice ball.

  In the present embodiment, the first upper forming mold 4a and the second upper forming mold 4b are respectively paired with the upper forming mold 4, and the first rice ball forming hole 5a and the second rice ball corresponding thereto. Although two rice balls are formed at the same time by each of the pair of lower-side forming molds 5b, the present invention is not limited to this. For example, a single rice ball is formed, Or you may set it as the structure by which three or more rice balls are formed.

  As shown in FIGS. 1 and 5, the support frame 2 is formed in a substantially U-shaped frame shape, and is arranged on the support base 1 in a vertical direction. Inside the support frame 2, substantially central left and right side plates of a so-called concoidal approximate parallel motion brake plate 6 are pivotally attached to the support frame 2 via a support shaft 7. The connecting shaft 8 projecting outside the front end left and right side plates is connected to a pair of left and right arms 10 of the upper forming frame 4 through a vertically long opening 9 formed in both sides of the support frame 2. Further, the left and right side plates of the brake plate 6 are connected to both ends of a U-shaped frame-like crank 11 so as to be rotatable by a shaft portion 23, and the tip ends of both ends of the crank 11 are connected to the support frame 2 by a shaft portion 24. It is pivotally attached so that it can rotate. Further, one end of the spring 12 is hung at the center portion of the crank 11 and the other end of the spring 12 is hung on the lower front side of the support frame 2 so that the brake plate 6 itself is constantly urged in the elevation rotation direction. I am letting.

  As shown in FIGS. 5 and 8 (b), a substantially S-shaped arm-side guide groove 13 formed by communicating a linear groove 13a and an arc groove 13b is formed at both end portions of the arm 10, and is supported. A roller 14 pivotally attached to both ends of the frame 2 is engaged with the arm-side guide groove 13. Further, as shown in FIGS. 5 and 8A, a roller 15 is pivotally mounted at substantially the center on both sides of the arm 10, and both ends of the arm 10 are pivotally attached to the support frame 2 by shaft portions 25. The roller 15 is loosely fitted in a substantially L-shaped guide hole 16 in which a horizontal groove 16a and a circular arc groove 16b are formed in a lower bulging portion at substantially the center of both ends of the operation lever 3 thus configured. Then, as shown in FIGS. 5 and 9, when the brake plate 6 is rotated in the depression direction by the manual pushing operation of the operation lever 3, the crank 11 rotates with the brake plate 6 along the concoid curve with respect to the support frame 2. By moving, the connecting shafts 8 on the left and right ends of the brake plate 6 are moved up and down along a pseudo straight line. That is, when the roller 14 slides up and down relatively in the linear groove 13 a region of the arm side guide groove 13 by manual operation of the operation lever 3, the upper forming mold 4 at the tip of the arm 10 is in the lower forming mold 5. At this time, the upper forming mold 4 is moved up and down in a horizontal state by the concoidal approximate parallel movement of the brake plate 6.

  As shown in FIG. 6 and FIG. 8 (b), the up-and-down movement of the connecting shaft 8 along the quasi-straight line causes the roller 14 to move upward in the linear groove 13 a of the arm-side guide groove 13. The first upper forming mold 4a and the second upper forming mold 4b of the forming mold 4 are fitted into the first onigiri forming hole 5a and the second onigiri forming hole 5b, respectively, while maintaining the horizontal state. A rice ball of a predetermined shape is formed.

  As shown in FIGS. 5 and 7, both ends of the operating lever 3 are pivotally attached to one end of a rod-like link 17 arranged vertically, and the other end side of the link 17 is supported. In the base 1, it is connected to one end which is a power point portion of a lever plate 19 which can swing left and right via a fulcrum shaft 18. Further, a bottom plate Q fitted into the first onigiri formation hole 5a and the second onigiri formation hole 5b of the lower forming form 5 which are in communication with each other is provided at the other end which is the action point portion of the insulator plate 19. An abutting portion 20 for upward movement is provided so as to protrude vertically upward. In FIG. 1, reference numeral 26 denotes a loose fitting hole of the link 17 provided on the support base 1.

  Therefore, after the rice ball molding, after the operating lever 3 is pushed up and the upper forming frame 4 is lifted and retracted in the elevation direction via the arm 10 (position shown by the two-dot chain line in FIG. 5), as shown in FIG. Further, when the operation lever 3 is pushed further into the back side, the roller 15 is relatively slid along the vertically elongated circular arc groove 16b of the guide hole 16 so that the lever plate is connected via the link 17. As the pad 19 is pushed down, the abutting portion 20 on the leading end side of the insulator plate 19 is raised, and the bottom plate Q of each of the first rice ball forming hole 5a and the second rice ball forming hole 5b is pushed up from below, so that the rice ball after molding is formed. Can be easily removed.

  Further, as shown in FIGS. 5 and 9, a stopper pin 21 is provided on the upper end side surface of the support frame 2 so as to project the arm 10 from rising in an excessive elevation direction. Further, a locking roller 22 for receiving an intermediate portion of the spring 12 is fixed below the brake plate 6 at the center of the shaft portion 25 of the operation lever 3. The spring 12 is prevented from obstructing the operation of the brake plate 6 moving in the direction. The bottom plate Q is formed in the same size and shape as the upper forming mold 4.

Next, an example of use and operation of the best mode configured as described above will be described.
First, as shown in FIG. 6A, a predetermined amount of cooked rice P is accommodated in the lower forming mold 5. At this time, the operation lever 3 is held at the elevation angle position by the tension of the spring 12. Further, as shown in FIG. 9, the brake plate 6 is in a right-up state, and the connecting shaft 8 between the brake plate 6 and the arm 10 is located at the upper end of the opening 9 of the support frame 2, and FIG. As shown, the roller 15 that connects the arm 10 and the operating lever 3 is located at the corner portion of the guide hole 16 of the operating lever 3, and the support frame 2 and the arm 10 are connected as shown in FIG. The roller 14 to be linked is located at the lower end of the arc groove 13 b of the guide hole 13 of the arm 10.

  Then, as shown in FIG. 6B, when the operation lever 3 is manually pushed, the arm 10 is pushed down by the relative slide of the roller 15 engaged with the guide hole 16 of the operation lever 3, and shown in FIG. Thus, the connecting shaft 8 between the brake plate 6 and the arm 10 descends from the upper end of the opening 9 of the support frame 2 toward the lower end, and as shown in FIG. 8B, the support frame 2 and the arm 10 are moved. The roller 14 to be linked moves from the arc groove 13b of the guide hole 13 of the arm 10 to the linear groove 13a, whereby the upper forming mold 4 is rotated to the position of the lower forming mold 5.

  Further, as shown in FIG. 6C, when the operation lever 3 is manually pushed to a substantially horizontal position, the brake plate 6 is lowered to the right as shown in FIG. The connecting shaft 8 is positioned at the lower end of the opening 9 of the support frame 2, and as shown in FIG. 8A, the roller 15 that connects the arm 10 and the operation lever 3 is horizontal to the guide hole 16 of the operation lever 3. On the other hand, as shown in FIG. 8B, the roller 14 relatively slides upward along the linear groove 13 a of the arm side guide groove 13 as shown in FIG. 8B. At this time, the upper forming mold 4 is inserted into the lower forming mold 5 in a parallel state by the concoidal approximate parallel movement of the brake plate 6, and the first onigiri forming hole 5a and the second onigiri forming hole 5b are respectively inserted. A rice ball of a predetermined shape is formed.

  After the rice ball molding, as shown in FIG. 6 (d), when the operation lever 3 is pushed up and moved by hand, the operation lever 3, the arm 10 and the brake plate 6 are respectively shown in FIGS. 6 (b) to 6 (a). ), And further, as shown in FIG. 7, the operating lever 3 is pushed inward, whereby the roller 15 is relatively slid along the circular arc groove 16b of the guide hole 16, thereby the link 17 As the insulator plate 19 is pushed down through the butt, the abutting portion 20 on the tip side of the insulator plate 19 is raised, and the bottom plate Q fitted into the first rice ball forming hole 5a and the second rice ball forming hole 5b is moved from below. By being pushed up, the rice balls after molding can be easily taken out. In addition, in this example, each shape of the rice ball forming holes 5a and 5b is formed in a triangle as shown in FIG. 4, but it is needless to say that other shapes such as a square may be used.
