  Hereinafter, an embodiment as an example of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

  As shown in FIGS. 1 and 2, the cooked rice supply apparatus M according to the present embodiment includes a hopper 1 into which cooked rice R (for example, cooked rice R mixed with seasonings such as vinegar and sugar) is introduced. The rice cooker 2 that dissolves the cooked rice R supplied from the hopper 1 and the cooked rice R that has been unwound in the cooked rice cooker 2 are compressed in a plate shape from above to below using rollers 5 (5a, 5b). The roller unit 4 that feeds out, the divided shutter 6 that divides the continuous plate-shaped cooked rice R fed by the roller unit 4 in a direction orthogonal to the conveying direction, and the plate-shaped cooked rice R that is divided by the divided shutter 6 are received and advanced. A moving plate 8 and a control unit 10 serving as a control means including a microcomputer for controlling the driving of the entire apparatus such as the roller unit 4, the divided shutter 6, the plate 8, and a driving means described later are provided. .

  The hopper 1, the rice cracker 2, the roller unit 4, the divided shutter 6 and the plate 8 are arranged from the upper side to the lower side.

  Further, on the front side of the cooked rice supply apparatus M, a touch panel 11 including a liquid crystal display unit is provided. Then, when the user operates the touch panel 11, the thickness of the plate-shaped cooked rice R, the length of the divided plate-shaped cooked rice R, and the like can be set. Note that the rotation speed of the roller 5 and the division timing of the divided shutter 6 are defined according to the set content, whereby a continuous plate-shaped cooked rice R having a thickness matching the set content is sent out from the roller unit 4 and the plate The cooked rice R is divided by the divided shutter 6 into a length suitable for the set content.

  The divided rice R is dropped and placed on the plate 8 on which, for example, a sheet-like laver is set and moved to the retracted position. And when the said plate 8 moves to an advance position, after putting a desired ingredient on the rice R, the front and back of the said plate 8 are pushed by pressing down the start button 9 provided in the right front side of the rice supply apparatus M. The seaweed rolls are made by raising and joining together.

  Here, the cooked rice cracking unit 2 has a plurality of cracked blades 3, and supplies the roller unit 4 while unrolling the cooked rice R from the hopper 1 by the rotation of the cracked blades 3. .

  In the roller unit 4, a plurality of pairs of rollers 5 a and 5 b are arranged along the supply direction of the cooked rice R. The plurality of pairs of rollers 5a and 5b are arranged so that the interval is narrowed from the upstream side to the downstream side in the supply direction of the cooked rice R, and the rice is rotated by a driving means (not shown). While R is compressed into a plate shape, it is transferred downward.

  Now, as shown in FIGS. 2 and 3, the roller unit 4 described above is detachably accommodated in a unit accommodating chamber 12 formed in the cooked rice supply apparatus M. The unit accommodating chamber 12 is opened forward, and when the cover member 13 is attached, the unit accommodating chamber 12 is closed and the roller unit 4 located inside is concealed.

  A restriction groove (not shown) for restricting the front and rear position of the roller unit 4 is formed on the bottom surface of the unit housing chamber 12 so as to extend in the lateral direction. Therefore, by removing the cover member 13 and pushing the roller unit 4 into the unit housing chamber 12 from the front and fitting it into the restriction groove, the movement of the roller unit 4 is restricted and the lateral direction (the axis of the roller 5) (Direction) becomes movable. The restriction of the front and rear position of the roller unit 4 may be other than the restriction groove, and for example, a frame body that supports the front and rear of the roller unit 4 may be used.

  The cover member 13 has an interlock function, and when the cover member 13 is mounted in the normal position, the magnetic field of a magnet (not shown) attached to the back side of the cover member 13 is magnetized on the apparatus body side. It is detected by a sensor (not shown). If the magnetic sensor detects that the cover member 13 is attached to the normal position in this way, the control unit 10 permits the operation of the driving means.

  4 and 5, the roller unit 4 includes the above-described plural (here, two pairs) rollers 5 and a frame 14 that supports these rollers 5.

  The frame 14 is spanned between two side wall plates 14a (an example of a frame member) facing and positioned on both sides, and both ends in the width direction are engaged with the side wall plates 14a. It is comprised by three crossing plates 14b (an example of a frame member) of the front-back part and a bottom part.

  In the case of the present embodiment, the side wall plate 14a and the crossing plate 14b are made of a resin material such as polypropylene or fluororesin, for example. However, various materials such as metal can be applied as long as a portion that is elastically deformed (details will be described later) can be provided.

  In each side wall plate 14a, a bearing portion 14a-1 that fits and supports the rotation shaft 5aa of one roller 5a-1 located on the upstream side in the feed direction of the cooked rice R opens upward, and the other side A bearing portion 14a-2 that fits and supports the rotation shaft 5aa of the roller 5a-2 is formed to open in the lateral direction. Further, each side wall plate 14a is formed with a bearing portion 14a-3 that is fitted and supported with the rotation shaft 5ba of one roller 5b-1 located downstream in the feed-out direction of the cooked rice R. Has been.

  The front portion of the side wall plate 14a is formed with a curved cutout portion 14a-4. A shaft coupling (not shown) for transmitting the driving force of the driving means, a roller positioning member (not shown), and the like. The other roller 5b-2 on which the rotation shaft 5ba is supported is positioned. The roller 5b-2 is structured such that the roller 5b-2 can be moved by a motor and a link mechanism (both not shown) so that the distance from the roller 5b-1 is changed. Accordingly, when the user sets the plate-shaped cooked rice R to a desired thickness by operating the touch panel 11, the motor rotates by an amount corresponding to the setting, and the roller 5 b-2 moves to move the roller 5 b-1. The interval is adjusted.

  As shown in the figure, the outer peripheral shapes of the pair of rollers 5a located on the upstream side in the feed direction of the cooked rice R and the pair of rollers 5b located on the downstream side in the feed direction of the cooked rice R are different from each other. The interval of the roller 5b is narrower than that of the roller 5a.

  Now, as shown in detail in FIG. 6, the side wall plate 14a and the crossing plate 14b constituting the frame 14 are engaged with the engaging part 20 in which the side wall plate 14a is detachably engaged with the end of the crossing plate 14b interposed therebetween. Is formed.

  Here, the engaging portion 20 formed on the side wall plate 14a is a first engaging portion 21 sandwiching the transverse plate 14b. Further, the engaging portion 20 formed on the transverse plate 14b is a second engaging portion 22 into which the first engaging portion 21 formed on the side wall plate 14a is elastically deformed and fitted.

  The first engaging portion 21 formed on the side wall plate 14a includes a lock piece 21a having a lock claw 21a-1 formed at the tip and two protruding pieces 21b. In addition, the second engaging portion 22 formed on the transverse plate 14b is formed with a locking piece insertion portion 22a in which a locking portion 22a-1 to which the locking claw 21a-1 is locked is formed and into which the locking piece 21a is fitted. And two projecting piece fitting portions 22b into which the projecting pieces 21b are fitted.

  The lock piece 21a constituting the first engagement portion 21 is fitted into a lock piece insertion portion 22a formed on one surface (here, the outer surface) of the crossing plate 14b, thereby forming the first engagement portion 21. The two projecting pieces 21b are fitted into projecting piece fitting portions 22b formed at two corners on the opposite surface (in this case, the inner surface) of the transverse plate 14b.

  As described above, the frame 14 according to the present embodiment includes the two side wall plates 14a and the three crossing plates 14b bridged between the side wall plates 14a. Accordingly, the second engaging portions 22 are formed at both ends of each transverse plate 14b, and the first engaging portions 21 correspond to the second engaging portions 22 of these transverse plates 14b, respectively. Three portions are formed on the side wall plate 14a.

  When the frame 14 is assembled, as shown in FIG. 7, the first engaging portion 21 formed on the side wall plate 14 a and the crossing plate 14 b are formed to correspond to the first engaging portion 21. The side wall plate 14a is pushed in the longitudinal direction of the crossing plate 14b.

  Then, the lock claw 21a-1 is pushed up by the lock claw 21a-1, and the lock piece 21a is elastically deformed so that the lock claw 21a-1 is fitted into the engagement part 22a-1. Sometimes the elastic deformation is released and the lock piece 21a returns to its original shape, and the lock piece 21a is fitted into the lock piece fitting portion 22a and engaged. Then, when the lock claw 21a-1 is fitted into the locking portion 22a-1, the separation between the side wall plate 14a and the transverse plate 14b is prevented. At the same time, the two protruding pieces 21b are fitted into the protruding piece fitting portions 22b, respectively.

  The lock piece 21a is elastically deformed to release the engagement between the lock claw 21a-1 and the locking portion 22a-1, and in this state, the side wall plate 14a is moved in the longitudinal direction of the transverse plate 14b (when both are engaged). If the slide is made in the opposite direction), the engagement between the side wall plate 14a and the transverse plate 14b is released.

  In this way, the first engaging portion 21 of the side wall plate 14a is elastically deformed and fitted into the second engaging portion 22 of the crossing plate 14b, so that the side wall plate 14a is inserted into the crossing plate as shown in FIG. 14b is engaged so that attachment or detachment is possible.

  Then, one plate (here, the side wall plate 14a) is detachably engaged with the other plate (here, the transverse plate 14b) sandwiched therebetween, so that both can be securely coupled and the coupling can be easily released. Yes. Therefore, by configuring the frame 14 with such a structure, the frame 14 can be easily disassembled while ensuring the rigidity of the frame 14. Further, the assembly after disassembling and cleaning the frame 14 can be easily performed by merely engaging the side wall plate 14a and the transverse plate 14b with one touch.

  In the present embodiment, the engaging portion 20 (that is, the second engaging portion 22) of the transverse plate 14b is sandwiched between the engaging portions 20 (that is, the first engaging portion 21) of the side wall plate 14a. However, conversely, the engaging portion 20 of the transverse plate 14b may be detachably engaged with the engaging portion 20 of the side wall plate 14a interposed therebetween.

  In addition, sandwiching the transverse plate 14b with the side wall plate 14a does not require pressing the second engaging portion 22 of the transverse plate 14b from both sides with the first engaging portion 21 of the side wall plate 14a. It is sufficient that the engaging portion 21 is fitted on both sides of the second engaging portion 22.

  Furthermore, in the present embodiment, the protruding piece 21b is fitted in two corners on the opposite surface to the lock piece 21a, but only one location on the opposite surface is sufficient, and it is not always necessary to have two locations. , Not the corner. That is, various forms can be employed for the sandwiching, and for example, both sides may be sandwiched between the lock pieces.

  However, if the two corners of one side of the transverse plate 14b and the opposite side are sandwiched as in the present embodiment, the coupling becomes more reliable, and as a result, the rigidity of the frame is further improved.

  Here, the bearing portions 14a-1, 14a-2, 14a-3 of the frame 14 and the rollers 5a-1, 5a-2, 5b-1 are supported by these bearing portions 14a-1, 14a-2, 14a-3. The rotating shafts 5aa, 5ba are fitted when the types and orientations of the rollers 5a-1, 5a-2, 5b-1 are normal with respect to the bearing portions 14a-1, 14a-2, 14a-3. In other cases, it has a shape that cannot be fitted.

  That is, the diameter of the rotation shaft 5ba of the roller 5b located downstream in the supply direction of the cooked rice R is larger than the diameter of the rotation shaft 5aa of the roller 5a positioned upstream in the supply direction of the cooked rice R. The bearing portions 14a-1 and 14a-2 that support the roller 5a and the bearing portion 14a-3 that supports the roller 5b have widths corresponding to the diameters of the rotary shafts 5aa and 5ba.

  Therefore, as shown in FIG. 9, when the types of the rollers 5a and 5ba to be attached are not regular, they cannot be fitted.

  Further, regarding the rotation shaft 5aa of the roller 5a, the diameter of one rotation shaft 5aa1 (FIG. 4) is different from the diameter of the other rotation shaft 5aa2 (FIG. 10). And the bearing parts 14a-1 and 14a-2 which support the said roller 5a become the width | variety corresponding to the diameter of each rotating shaft 5aa1 and 5aa2. Further, regarding the rotation shaft 5ba of the roller 5b, the diameter of the one rotation shaft 5ba1 (FIG. 4) is different from the diameter of the other rotation shaft 5ba2 (FIG. 10). Similarly, the bearing portion 14a-3 that supports the roller 5b has a width corresponding to the diameter of each of the rotation shafts 5ba1 and 5ba2.

  Therefore, as shown in FIG. 10, even if the type of the rollers 5a and 5b to be attached is regular, if the direction is not regular, the fitting is impossible.

  Then, by adopting such a structure that can be fitted only when the types and orientations of the rollers 5a-1, 5a-2, 5b-1 are regular, the frame is disassembled and washed and then reassembled. When the rollers 5a and 5b are assembled, it is possible to prevent the rollers 5a and 5b from being assembled incorrectly (misassembled).

  Strictly speaking, in FIG. 9, the roller 5a having the rotation shaft 5aa with a small diameter is fitted into the bearing portion 14a-3 into which the roller 5b having the rotation shaft 5ba with a large diameter is fitted. The roller 5b having the thick rotating shaft 5ba cannot be fitted into the bearing portions 14a-1 and 14a-2 to which the roller 5a having the thin rotating shaft 5aa is fitted, and as a result, erroneous assembly is prevented. It will be.
