  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 the magnet 15 (FIG. 7) attached to the back side of the cover member 13 causes the magnetic field on the apparatus main body side. It is detected by the sensor 18 (detection member). 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 includes two side wall plates 14a positioned on both sides, and three transverse crossings, which are spanned between the side wall plates 14a and are fitted to the side wall plates 14a at both ends in the width direction. It is comprised with the plate 14b.

  In each side wall plate 14a, a bearing portion 14a-1 into which one roller 5a-1 located on the upstream side in the delivery direction of cooked rice R is rotatably fitted opens upward, and the other roller 5a-2 is opened. Is formed so as to open in the lateral direction. Furthermore, each side wall plate 14a is formed with a bearing portion 14a-3, which is rotatably fitted with one roller 5b-1 positioned on the downstream side in the feed direction of the cooked rice R.

  The front portion of the side wall plate 14a is formed with a curved notch 14a-4, and is connected to a shaft coupling 16a (FIG. 6) for transmitting the driving force of the driving means and a roller positioning member 17b (FIG. 6). The other supported roller 5b-2 is located.

  The roller 5b-2 is not supported by the frame 14, but has a structure that can be moved by the motor 19a and the link mechanism 19b (FIG. 6) so that the distance from the roller 5b-1 changes. Accordingly, when the user sets the plate-shaped cooked rice R to a desired thickness by operating the touch panel 11, the motor 19 rotates by an amount corresponding to the setting, and the roller 5b-2 moves to move the roller 5b-1. The interval between and is adjusted.

  As shown in FIG. 6, in the unit accommodating chamber 12, a driving force conveying portion 16 b such as a gear train that conveys the driving force of the driving means and the conveyed driving force are transmitted to the roller 5 for rotational driving. A transmission unit 16 in which a shaft coupling 16 a (transmission means) is assembled is disposed on one side of the roller unit 4. The shaft coupling 16a is provided corresponding to each roller 5, and when the shaft coupling 16a is coaxially coupled with the roller 5, the roller is rotationally driven by the driving force of the driving means.

  The shaft coupling 16a coupled to the roller 5b-2 is rotatably supported by the link mechanism 19b and moves as described above by the link mechanism 19b.

  As described above, when the roller unit 4 is pushed into the unit accommodating chamber 12 and fitted into the restriction groove, the movement of the roller unit 4 is restricted and can move in the lateral direction, that is, the axial direction of the roller 5. It becomes a state. Therefore, by sliding the roller unit 4 in the lateral direction along the restricting groove (in the present embodiment, the left side when the cooked rice supply device M is viewed from the front), the shaft coupling 16a provided in the transmission unit 16 becomes a roller. 5 is combined.

  A positioning member 17 for positioning the roller unit 4 is disposed on the opposite side of the roller unit 4 from the transmission unit 16.

  The positioning member 17 is supported by the shaft 20 and is movable in the axial direction of the roller 5.

  Here, the roller unit 4 is located at a position where the shaft coupling 16a provided in the transmission unit 16 is coupled to the roller 5, that is, a position where the roller 5 is rotationally driven by the driving means (hereinafter also referred to as “predetermined position”). When the positioning member 17 is moved (in this case, slid leftward) and brought into contact with the roller unit 4, the position becomes the first position for positioning the roller unit 4. Further, when the positioning member 17 is moved away from the roller unit 4 by moving the positioning member 17 in the opposite direction (in this case, sliding to the right side), the position can be separated from the predetermined position described above. Becomes the second position.

  Note that the first position of the positioning member 17 is a position where the roller unit 4 is positioned, and is therefore only one position where the roller unit 4 is in contact with the first position. On the other hand, the second position is a position at which the roller unit 4 can be separated from the predetermined position. Therefore, the second position is not limited to one place on the moving end opposite to the first position. And a position in the middle of the moving end is also included.

  The positioning member 17 is for a roller that positions the frame 14 of the roller unit 4 by rotatably supporting one end side of the rotary shaft of the roller positioning member 17a (first positioning member) and the roller 5b-2 described above. It is comprised by the positioning member 17b (2nd positioning member). The frame positioning member 17a is supported by the shaft 20a, and the roller positioning member 17b is supported by the shaft 20b and moves in the axial direction of the roller 5, respectively.

  The roller positioning member 17b that supports the roller 5b-2 is rotatably supported by the link mechanism 19b, and operates in synchronization with the other link mechanism 19b by driving the motor 19a. The roller 5b-2 is moved so that the interval of.

  In the present embodiment, the coupling 16a and the roller 5 are coaxially coupled at a predetermined position so that the driving force of the driving means is transmitted to the roller 5, but this is the roller unit 4. This is because the driving force can be transmitted to the roller 5 simply by setting the position to a predetermined position. However, it goes without saying that the driving force of the driving means may be transmitted to the roller 5 by a structure other than such a coupling structure.

  Further, in this embodiment, the frame positioning member 17a and the roller positioning member 17b are provided as the positioning member 17. However, only one of the positioning members may be provided, and further, the positioning of the roller unit 4 may be performed. As long as it can be done, various forms of positioning members can be used. The roller positioned by the roller positioning member 17b is not limited to the roller 5b-2 that is not supported by the frame 14 as in the present embodiment, and may be other rollers 5.

  As shown in FIG. 7, a regulating member 21 is attached to the cover member 13 on the unit housing chamber 12 side with screws 22.

  The restricting member 21 includes a base portion 21-1 along the back surface of the cover member 13, a first restricting portion 21 a that is bent substantially at right angles to the base portion 21-1 and extends toward the inside of the unit accommodating chamber 12. It has the 2nd control part 21b. Further, the regulating member 21 is formed with an interference portion 21 c that interferes with the positioning member 17. The surface of the interference part 21c is arranged along the moving direction of the positioning member 17, and when the positioning member 17 is not in the first position (in the second position), the interference part 21c (of the Surface).

  The portion of the regulating member 21 that interferes with the positioning member 17 does not have to be the interference portion 21c having such a structure. However, according to the structure shown in the present embodiment, the regulating member 21 is at the second position. A structure that interferes with a certain positioning member 17 can be easily realized.

  Here, when the positioning member 17 described above is in the first position (position where the roller unit 4 is positioned at a predetermined position), the regulating member 21 regulates the movement of the positioning member 17 to place the cover member 13 in the normal position. It can be attached to.

  That is, as shown in the figure, the first restricting portion 21a is located on the side of the frame positioning member 17a in the first position and restricts movement to the second position. Moreover, the 2nd control part 21b is located in the side of the roller positioning member 17b in the same 1st position, and has controlled the movement to a 2nd position. Accordingly, the roller unit 4 is prevented from being displaced from the predetermined position by the positioning member 17 whose movement is restricted by the restriction member 21.

  As shown in detail in FIG. 8, since the regulating member 21 is located on the side of the positioning member 17 and regulates movement, the regulating member 21 interferes with the positioning member 17 (interference portion 21 c thereof). Therefore, the cover member 13 is mounted in the normal position.

  On the other hand, when the positioning member 17 is in the second position (position where the roller unit 4 can be separated from the predetermined position), the regulating member 21 interferes with the positioning member 17 (interference portion 21c thereof). The cover member 13 cannot be mounted at the normal position.

  That is, as shown in FIGS. 9 and 10, when the frame positioning member 17 a and the roller positioning member 17 b are in the second position, the surfaces of these positioning members 17 are aligned with the movement direction of the positioning member 17. Interfering with the shaped interference part 21c. In these drawings, the position where the interference occurs is indicated by symbol A.

  In the case shown in the figure, the interference part 21c and the positioning member 17 are represented as being fitted, but this is an easy-to-understand representation of the interfering part. Both will collide.

  When the regulating member 21 provided on the cover member 13 interferes with the positioning member 17 that positions the roller unit 4, the cover member 13 is obstructed by the positioning member 17 and cannot be mounted at the normal position.

  Thus, according to the cooked rice supply apparatus M of the present embodiment, when the roller unit 4 that has become detachable is mounted in the unit accommodating chamber 12, the roller 5 is rotated by the driving means at a predetermined position. When the roller unit 4 is set and the positioning member 17 is moved to the first position to position the roller unit 4, the cover member 13 is mounted at the normal position.

  On the other hand, if the roller unit 4 is not set at a predetermined position where the roller 5 is rotationally driven by the driving means, the positioning member 17 cannot move to the first position. Since it is in the position, the regulating member 21 provided on the cover member 13 interferes with the positioning member 17 and the cover member 13 cannot be mounted at the normal position.

  Therefore, the roller unit 4 can be reliably mounted in the unit accommodating chamber 12 depending on whether or not the cover member 13 is mounted at the regular position.

  Moreover, as described above, in the present embodiment, when the cover member 13 is mounted at the regular position, the magnetic field of the magnet 15 attached to the cover member 13 is detected by the magnetic sensor 18 on the apparatus main body side, and the control unit. 10 has an interlock function that the operation of the driving means is permitted.

  Therefore, when the roller unit 4 is not mounted at the predetermined position of the unit storage chamber 12 and the cover member 13 is not mounted at the regular position, the operation of the driving means is not permitted by the control unit 10, so that the roller unit 4 The operation of the apparatus is not started with the mounting failure.

  Now, in the present embodiment, as shown in FIG. 11, a plurality of types (here, two types) of sizes of the roller unit 4 are prepared.

  That is, as apparent from a comparison between FIG. 11A and FIG. 11B, both are formed on both sides of the frame 14 while the width of the frame 14 and the roller 5 is different from each other. The widths of the positioning portions to the predetermined positions are common to each other.

  That is, the width W1 of the roller 5 shown in FIG. 11A is 178 mm, for example, while the width W2 of the roller 5 shown in FIG. 11B is 200 mm, for example. On the other hand, the width P of the positioning part to the predetermined position is 224 mm, for example.

  This is because the width P of the positioning portion defined by the coupling position S1 of the roller 5 with the shaft coupling 16a and the contact position S2 of the positioning member 17 is the same as that of the roller unit 4 shown in FIG. This is the same as the roller unit 4 shown in FIG. And in order to implement | achieve such a structure, in the roller unit 4 shown to Fig.11 (a), the length of the rotating shaft of the both sides of the roller 5 is longer than the roller 5 of the roller unit 4 shown in FIG.11 (b). It is getting longer.

  Then, by preparing a plurality of types of roller units 4 in this way, it is possible to change the size of the mounted roller unit 4 without changing the structure on the apparatus side, and to change the size of the mounted roller unit 4 to a plate having a width desired by the user. Can be obtained easily.

  In the present embodiment, two types of roller units 4 are prepared, but may be three types or more.
