  FIG. 1 is a perspective view showing a molded product manufacturing apparatus 1 including a molding apparatus 10 and a take-out apparatus 30 according to an embodiment of the present invention.

  In FIG. 1, the molded product manufacturing apparatus 1 according to the present embodiment compresses the cooked rice R (see FIGS. 9 to 20), which is a material, by the molding apparatus 10 to form a rice ball that is a molded product, and takes out the device 30. The rice balls molded by the above method are taken out.

  The shaping | molding apparatus 10 has the shaping | molding die 11 comprised by the lower side mold | type 11a in which the accommodation hole 11a-1 in which cooked rice is accommodated was formed, and the upper mold | type 11b fitted in the accommodation hole 11a-1. Then, by operating the operation lever 12 (operation unit) and fitting the upper mold 11b into the lower mold 11a in which the cooked rice is stored, the cooked rice is pressed to form a rice ball having a predetermined shape.

  As shown in FIG. 2, the lower mold 11a of the mold 11 includes the frame body portion 11a-2 in which the accommodation hole 11a-1 is formed and the movable plate portion 11a fitted in the accommodation hole 11a-1. -3. Cutout portions 11a-3a are formed at two opposing positions on the bottom surface of the movable plate portion 11a-3, and a protrusion into which the cutout portion 11a-3a is fitted into the lower end portion of the accommodation hole 11a-1. Portions 11a-1a are formed (see FIG. 15). Therefore, the movable plate portion 11a-3 is movable up and down within the accommodation hole 11a-1, and the notch portion 11a-3a is fitted into the projection portion 11a-1a at the lower end of the accommodation hole 11a-1. It is impossible to leave from below.

  In the case of the present embodiment, the frame body part 11a-2 of the lower mold 11a has a substantially square shape when viewed from the plane, and there are four (a plurality of frame bodies 11a-2) with respect to the frame body part 11a-2 having such a shape. ) Receiving holes 11a-1 are formed. That is, a total of four accommodation holes 11a-1 are formed side by side in the width direction of the pedestal portion 14 described later and two in the front-rear direction.

  The upper die 11b is formed by integrally forming four fitting portions 11b-1 that are fitted into the four receiving holes 11a-1 formed in the lower die 11a. A screwing portion 11b-2 for fixing the mold 11b to a press arm 13 (supporting member) described later is provided.

  In FIG. 1, the molding apparatus 10 includes a pedestal portion 14 on which the above-described lower mold 11a is placed, and a pair of support columns 15 are attached to both sides thereof. Further, the pedestal portion 14 is provided with a regulation rail 14b that regulates the position in the width direction of the lower mold 11a to be placed and allows movement in the front-rear direction, which is the attaching / detaching direction. 14 is provided with a contact piece 16 for regulating the position of the mounting back end of the lower mold 11a placed on the lower mold 11a. Accordingly, the lower mold 11a is regulated by the regulation rail 14b and the contact piece 16, and is positioned at a predetermined position of the pedestal portion 14.

  A groove portion 11a-2a into which the contact piece 16 is fitted when the lower die 11a is mounted on the pedestal portion 14 in the correct direction is formed on the side surface of the frame portion 11a-2 constituting the lower die 11a. Has been.

  The press arm 13 that supports the upper die 11b includes a mounting plate 13a to which the upper die 11b is attached, and a pair of arm portions 13b that are erected on both ends of the mounting plate 13a.

  On the other hand, the pair of support columns 15 located on both sides of the pedestal portion 14 includes a pair of first link members 17 that are swingably attached to the arm portion 13 b of the press arm 13, and the first link members 17. A pair of second link members 18 that are swingably attached to the arm portion 13b of the press arm 13 at the lower side are respectively provided rotatably.

  In the present embodiment, the aforementioned operating lever 12 is provided integrally with the first link member 17, and the operating lever 12 is pushed down from a state where the upper mold 11b and the lower mold 11a are separated (FIG. 3). Thus, the first link member 17 and the second link member 18 are operated to lower the upper die 11b supported by the press arm 13. As a result, the upper die 11b is shifted to a state (FIG. 4) in which the upper die 11b is fitted in the accommodation hole 11a-1 of the lower die 11a, and the cooked rice contained in the accommodation hole 11a-1 is pressed to form a rice ball having a predetermined shape. It is formed.

  Here, in the present embodiment, the first link member 17 and the second link member 18 are mechanisms that move up and down by an approximate linear motion of the locus of the attachment site with the press arm 13. Specifically, the first link member 17 and the second link member 18 have a structure in which the locus of the attachment portion of the link rods 17b and 18b with the press arm 13 performs a concoidal approximate parallel motion.

  Next, the concoidal approximate parallel motion will be described with reference to FIG.

  In FIG. 5, the first link member 17 and the second link member 18 are constituted by cranks 17a and 18a, link rods 17b and 18b, and support shafts 17c and 18c. One end of each of the cranks 17a and 18a is rotatably attached to the support column 15, and one end of each of the link rods 17b and 18b is rotatably attached to the other end of the cranks 17a and 18a, and the other end is a press arm. 13 is swingably attached. Further, the support shafts 17c and 18c are provided on the support column 15 and are fitted into the long holes 17b-1 and 18b-1 formed in the link rods 17b and 18b so as to relatively move in the long holes 17b-1 and 18b-1. The link rods 17b and 18b are supported slidably with respect to the longitudinal direction of the link rods 17b and 18b and swingable with respect to the support column 15.

  In such a structure, when the operation lever 12 is pushed down in the state shown in FIG. 5A (the state in which the upper die 11b and the lower die 11a are separated), the cranks 17a and 18a are attachment portions of the column 15. Rotate around P1 as a fulcrum. Then, simultaneously with the rotation, the link rods 17b and 18b slide in the longitudinal direction while swinging around the support shafts 17c and 18c, and after the state shown in FIG. 5B, the state shown in FIG. The mold 11b is shifted to a state in which the mold 11b is fitted in the accommodation hole 11a-1 of the lower mold 11a. In this series of movements, the locus of the point P2, which is the attachment portion of the link bars 17b and 18b with the press arm 13, draws an approximate straight line.

  However, the mechanism of the first link member 17 and the second link member 18 is not limited to the concoidal approximate parallel motion mechanism shown in the present embodiment, and other mechanisms such as Scott Russell approximate parallel motion and Kempzevissev approximate parallel motion. Various known approximate parallel motion mechanisms can be employed.

  As described above, in the present embodiment, the pair of first link members 17 and the pair of second link members 18 are provided on the pair of support columns 15 attached to both sides of the pedestal portion 14. . That is, the link members 17 and 18 are two pairs. This is due to the following reason.

  That is, when there is a pair of link members, if only the pair of first link members 17 is provided, the above-described point P2 of the first link member 17 has an approximate parallel motion. However, since the point P2 of the second link member 18 does not exist, the press arm 13 freely swings about the point P2 of the first link member 17 as a fulcrum. Then, the posture of the upper die 11b attached to the press arm 13 becomes unstable.

  Therefore, by providing another pair of link members, in this case, by providing a pair of second link members 18, a point P2 of the first link member 17 and a point P2 of the second link member 18 As a result, the free swing of the press arm is restricted, so that the posture of the upper die 11b attached to the press arm 13 is stabilized.

  As a result, the upper die 11b attached to the press arm 13 can move up and down in an approximate straight line while maintaining a posture with the fitting portion 11b-1 facing downward.

  As described above, in the molding apparatus 10 according to the present embodiment, the pair of first link members 17 and the pair of first link members 15 that operate in the above-described concoidal approximate parallel motion are attached to the pair of support columns 15 that are attached to both sides of the base portion 14. Two pairs of link members called two link members 18 are rotatably provided. Then, the link members 17 and 18 are operated to lower the upper die 11b and are fitted into the receiving holes 11a-1 of the lower die 11a so as to press the upper die 11b from both sides via the press arm 13. It is out.

  Therefore, since it is possible to apply force evenly on both sides of the upper die 11b by the link members 17 and 18, a plurality of (here, four by the four accommodation holes 11a-1) as in the present embodiment. The whole cooked rice accommodated in the accommodation hole 11a-1 without adopting a high-rigidity mechanism using a slide bearing or the like, even when a rice ball is molded or a large rice ball is a molded product. It is possible to apply an even and sufficient force to the product, and it is possible to produce a product having no individual difference in terms of softness (hardness). In addition, the high-rigidity raising / lowering mechanism does not increase the overall weight of the apparatus and make it difficult to carry.

  Further, in the molding apparatus 10 of the present embodiment, the press arm 13 to which the upper die 11b is attached is attached to the link members 17 and 18 rotatably provided on the support column 15 so as to be able to swing. Since the upper die 11b is moved up and down by the swinging motion, it is possible to reliably perform the operation of fitting the forming die without adopting high precision lifting using a sliding bearing or the like.

  Further, in the molding apparatus 10 according to the present embodiment, the upper die 11b is lifted and lowered by the rotation motion and the swinging motion as described above. Therefore, even if the lifting mechanism does not have a cover for preventing foreign matter adhesion, the foreign matter Smooth operation is possible over a long period of time without deteriorating the operation due to adhesion.

  In addition, it is not necessary to employ such a highly rigid and highly accurate lifting mechanism, and a cover for preventing foreign matter adhesion is not necessary for the lifting mechanism. Cost can be reduced.

  Now, as shown in FIGS. 6 and 7, a coil spring 19 is fitted between the base portion 14 and the press arm 13. The coil spring 19 is fixed to the pedestal portion 14 and is held by a holding rod 20 (holding member) penetrating the press arm 13 so as not to come off.

  According to such a structure having the coil spring 19, when the operator depresses the operation lever 12 from the position shown in FIG. 6, the press arm 13 is lowered while compressing the coil spring 19 as shown in FIG. 7. Thereby, the upper mold | type 11b attached to the said press arm 13 is engage | inserted by the lower mold | type 11a, and the cooked rice in the accommodation hole 11a-1 is compressed.

  When the hand is released from the operation lever 12, the press arm 13 is pushed upward by the elastic force of the coil spring 19, and returns to the position shown in FIG.

  When the hand is released from the operation lever 12 in this way, the press arm 13 is automatically raised by the coil spring 19 and the upper die 11b returns to a position separated from the lower die 11a. Eliminates labor saving.

  Further, when the operation lever 12 is released, the operation lever 12 returns to the position shown in FIG. 6, so that the cooked rice in the accommodation hole 11a-1 does not remain compressed by forgetting to return the operation lever 12, The hardness of the onigiri to be molded can be made uniform.

  Next, as shown in FIG. 8, the molding apparatus 10 has a stopper 21 for abutting the lowered press arm 13 to regulate the lowered end of the press arm 13. The stopper 21 is screwed into a protruding piece 15a protruding forward from the support column 15 and extends in the vertical direction. Therefore, the descending end of the press arm 13 can be adjusted to an arbitrary position by turning the stopper 21 to change the height. The stopper 21 is provided with a lock nut 21a that is a lock mechanism for preventing a shift after the height of the stopper 21 is determined.

  Thereby, since it becomes possible to set the compression amount with respect to the cooked rice accommodated in the accommodation hole 11a-1 of the lower mold | type 11a of the upper mold | type 11b attached to the press arm 13, it shape | molds. The rice balls can be made uniform to a predetermined hardness.

  Now, the molded product manufacturing apparatus 1 is provided with a take-out device 30 for taking out the rice balls molded by the molding device 10 from the accommodation holes 11a-1 of the lower mold 11a separately from the molding device 10. ing.

  As described above, the lower mold 11a of the mold 11 is fitted into the frame body portion 11a-2 in which the accommodation hole 11a-1 is formed and the accommodation hole 11a-1 so that it can move up and down and cannot be detached from below. Movable plate portion 11a-3.

  Therefore, in the take-out device 30 for taking out the rice balls formed in the accommodation holes 11a-1, a push-up portion 30a that pushes up the movable plate portion 11a-3 when the lower mold 11a is placed is formed on the base plate 30b. It has a structure. A handle portion 30c is formed in front of the base plate 30b so that an operator can put his / her hand when handling the take-out device 30.

  Thereby, when the lower mold 11a pulled out from the pedestal part 14 is placed, the frame part 11a-2 is lowered by its own weight, and the movable plate part 11a-3 is relatively raised by the push-up part 30a. The rice ball in the accommodation hole 11a-1 is pushed up (see FIGS. 9 to 20).

  The take-out device 30 can be stored in the pedestal portion 14 of the molding device 10, and in the retracted position, the bottom surface is supported by the mounting plate 14 a-1 to which the leg portion 14 a of the pedestal portion 14 is attached, and is formed forward. The notched portion 30d is caught on the mounting plate 14a-1, thereby preventing unexpected detachment.

  In addition, since the taking-out device 30 is a separate body independent of the molding device 10, it can be freely arranged according to the work space, and is directed toward the molding device 10 as shown in FIGS. It can be placed on the right side, on the left side of the molding apparatus 10 as shown in FIG. 21, or in front of the molding apparatus 10 as shown in FIG.

  Since the take-out device 30 is separate from the molding device 10 as described above, the degree of freedom in work layout is improved, and a comfortable work environment can be obtained even in a narrow work space. Further, since the take-out device 30 can be stored in the pedestal portion 14 of the molding device 10, there is no need to secure a place for removing the take-out device 30 after work, and space for the entire device can be saved. it can.

  Next, the rice ball forming operation by the forming apparatus 10 having the above configuration will be described with reference to FIGS. Here, FIG. 9 to FIG. 14 are perspective views continuously showing each step (first step to sixth step) for manufacturing a rice ball by the molding apparatus 10, and FIG. 15 to FIG. FIG. 15 is a cross-sectional view corresponding to each step of FIG. 14.

  In the molding apparatus 10 of the present embodiment, the cooked rice R is weighed to a predetermined weight with a measuring instrument (not shown), and is put into the accommodation hole 11a-1 of the lower mold 11a as shown in FIGS. First step). In the present embodiment, since four accommodation holes 11a-1 are formed, this throwing operation is repeated four times and the cooked rice R is poured into all four accommodation holes 11a-1.

  Next, as shown in FIGS. 10 and 16, the lower mold 11a is inserted from the near side of the pedestal portion 14 until it abuts against the abutting piece 16 along the regulation rail 14b and is set in the molding apparatus 10 (the second device). Process).

  When the lower mold 11a is set in the molding apparatus 10 in this way, the operating lever 12 is pushed down against the elastic force of the coil spring 19 as shown in FIGS. 11 and 17 (third step). Then, the locus of the attachment portion of the first link member 17 and the second link member 18 to the press arm 13 draws an approximate linear motion (concoidal approximate parallel motion) and descends to the descending end that contacts the stopper 21. Then, the upper die 11b fixed to the press arm 13 is fitted into the accommodation hole 11a-1 of the lower die 11a. Thereby, the rice ball accommodated in the accommodation hole 11a-1 of the lower mold 11a is compressed with a predetermined force to form a rice ball.

  When the rice ball is molded, the hand is released from the operation lever 12 (fourth step). Then, as shown in FIGS. 12 and 18, the press arm 13 is pushed upward by the elastic force of the coil spring 19, and the upper die 11 b returns to a position away from the lower die 11 a. This completes the formation of the rice balls.

  When the formation of the rice balls is completed, as shown in FIGS. 13 and 19, the lower mold 11a is pulled forward from the pedestal portion 14 and the lower mold 11a is removed (fifth step).

  Finally, as shown in FIGS. 14 and 20, the lower mold 11a is placed on the take-out device 30 (sixth step). Then, the frame body part 11a-2 descends by its own weight, and accordingly, the movable plate part 11a-3 is relatively raised by the push-up part 30a, and the rice balls in the accommodation hole 11a-1 are pushed up and taken out.

  Although the invention made by the present inventor has been specifically described based on the embodiment, the embodiment disclosed in this specification is an example in all respects and is limited to the disclosed technology. Should not be considered. That is, the technical scope of the present invention should not be construed restrictively based on the description in the above-described embodiment, but should be construed according to the description of the scope of claims. All modifications are included without departing from the technical scope equivalent to the described technique and the gist of the claims.

  For example, in the embodiment described above, the lower mold 11a has four housing holes 11a-1, and the upper mold 11b has four fitting portions that fit into the housing holes 11a-1. Although 11b-1 is formed and the shaping | molding apparatus by which the four rice balls which are molded objects are shape | molded simultaneously is shown, in this invention, the number and magnitude | size of the accommodation hole 11a-1 and the fitting part 11b-1 are shown. The size can be set freely.

  For example, as shown in FIG. 23, a total of eight accommodation holes 11a-1, a fitting portion 11b-1, and the like in which four receiving holes and two fitting portions are arranged in one row can be formed. Alternatively, it may be a molding apparatus in which the accommodation holes 11a-1 and the fitting portions 11b-1 are formed one by one, and one onigiri, which is a molded product, is molded.

  In addition, even if the number of the accommodation holes 11a-1 and the fitting portions 11b-1 corresponding to the number of rice balls to be formed increases, the accommodation holes 11a-1 and the fitting portions 11b-1 are not limited to the width of the pedestal portion 14. Even if many are formed with respect to the direction, according to the molding apparatus of the present application, since the force is applied equally to both sides of the upper die 11b using the link members 17 and 18, the inside of each accommodation hole 11a-1 It becomes possible to apply force evenly to cooked rice.

  In the above description, the case where the present invention is applied to a molding apparatus and a molded product manufacturing apparatus for compressing and forming cooked rice into rice balls is not limited to this, but other than cooked rice and minced meat It can be applied to the molding of various materials such as vegetables, cereals, kneaded foods, etc. that have the property of retaining their shape once they are placed in a mold.
