  As shown in FIG. 1 and FIG. 2, the rolled sushi manufacturing apparatus M according to the present embodiment has a hopper 1 into which cooked rice R (for example, cooked rice R mixed with seasonings such as vinegar and sugar) is added. Then, the cooked rice unwinding portion 2 that unwinds the cooked rice R supplied from the hopper 1 and the cooked rice R that has been unwound in the cooked rice unwinding portion 2 are compressed in a plate shape from above to below using rollers 5 (5a, 5b). A feed roller unit 4 that feeds out, a divided shutter 6 that divides a continuous plate-shaped cooked rice R fed by the feed roller unit 4 in a direction perpendicular to the conveying direction, and a plate-shaped cooked rice R that is divided by the divided shutter 6. A forming plate 8 that is mounted on a plate mounting portion 7 that reciprocates on a guide rail (not shown) extending in the front-rear direction, and that moves forward and backward, a feed roller unit 4, a divided shutter 6, a plate mounting portion 7, and a forming plate 8 And a control unit 10 composed of a microcomputer or the like (control means) for controlling the driving of the entire device such as pre-described driving means.

  The hopper 1, the rice cracker 2, the feed roller unit 4, the divided shutter 6, the plate mounting portion 7, and the forming plate 8 are arranged from the top to the bottom.

  Further, on the front side of the rolled sushi manufacturing 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 suitable for the set content is sent out from the feed roller unit 4, The plate-shaped cooked rice R is divided by the divided shutter 6 into a length that matches the set content.

  Here, as shown in detail in FIG. 4, the molding plate 8 is made of, for example, a plurality of rectangular plate-like members 8a made of metal whose surface is coated with a fluororesin or the like, and are connected to each other via a hinge 8b so as to be freely bent. Has a structured.

  In this molding plate 8, a part (one sheet in the present embodiment) of the plate-like member 8 a-1 is fixed to the plate mounting portion 7 with a screw 14 and a washer plate 15. Further, the other plate-like member 8a has a bottom surface supported by the plate mounting portion 7, and the molded plate 8 is in a developed state as a whole. And plate-like members 8a other than the fixed plate-like member 8a-1 can be bent upward.

  In addition, since the diameter of sushi rolls is different for thick rolls, medium rolls, thin rolls, etc., the molding plate 8 of the present embodiment also corresponds to these, a thick winding molding plate, a middle winding molding plate, Different shaped plates 8 such as a thin-rolled shaped plate are prepared and are exchanged according to the diameter of the rolled sushi. Further, the size of the forming plate 8 is different in the longitudinal length with respect to the moving direction.

  From below the forming plate 8, a protruding piece 7a formed on the plate mounting portion 7 protrudes so as to be positioned forward and backward with respect to the moving direction. Further, at the position on the left and right with respect to the moving direction of the forming plate 8, the protruding piece 15 a that is the bent portion of the washer plate 15 described above is provided upright. And the area | region of the shaping | molding plate 8 enclosed by these protrusion pieces 7a and 15a turns into an area | region where plate-shaped cooked rice is mounted, and functions as positioning at the time of mounting a sheet-like laver for an operator.

  As shown in FIG. 2, below the forming plate 8 positioned at the forward end, the forming plate 8 mounted on the plate mounting portion 7 is bent by a roller-like protruding upper portion 16a so that the forming plate 8 is wound. A protruding roller unit 16 (protruding means) is disposed.

  The details of the drive mechanism including the protrusion roller unit 16 and the drive motor 17 (drive means) for driving the roller unit 16 will be described later.

  The divided cooked rice R is dropped and placed on the forming plate 8 on which, for example, sheet-like laver is set and moved to the retracted position by the plate mounting portion 7. Next, the molding plate 8 is moved to the forward position by the plate mounting portion 7, and after a desired ingredient is placed on the cooked rice R, the start button 9 provided on the right side of the rolled sushi manufacturing apparatus M is pressed. Then, the above-described thrust roller unit 16 is driven and the front and rear of the forming plate 8 are pushed up by the projecting upper portion 16a. And when bent so that it may be rolled in, the seaweed and rice on the shaping | molding plate 8 are wound so that an ingredient may be wrapped, and a seaweed roll is produced.

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

  Further, in the delivery 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 above-described delivery roller unit 4 is detachably accommodated in a unit accommodation chamber 12 formed in the rolled sushi manufacturing apparatus M. The unit storage chamber 12 is opened forward, and when the front cover 13 is attached, the unit storage chamber 12 is closed and the delivery roller unit 4 located inside is concealed.

  As shown in FIGS. 4 and 5, the upward roller unit 16 includes a first arm portion 16-1 and a second arm portion 16-2, and the first arm portion 16-1 is It is located closer to the drive motor 17 than the second arm portion 16-2. Further, the second arm portion 16-2 is rotatable with respect to the main body portion 16 b of the upward roller unit 16. The first arm portion 16-1 is attached to the first shaft 19-1 whose both ends are rotatably supported by the support plate 18a, and both ends of the second arm portion 16-2 are the support plate 18b. The second shaft 19-2 is rotatably supported by the second shaft 19-2.

  Here, a disc-shaped cam 20 is attached to the motor shaft 17 a of the drive motor 17 described above, and a swing arm 22 in contact with the cam 20 is provided in the holding box 21 holding the drive motor 17. It is attached. Further, a rod 24 having one end rotatably attached to the tip of the swing arm 22 and the other end rotatably attached to the tip of the transmission plate 23 fixed to the second shaft 19-2. Is provided.

  Accordingly, when the start shaft 9 is pressed and the motor shaft 17 a of the drive motor 17 rotates and the cam 20 rotates, the swing arm 22 in contact with the cam 20 swings according to the rotation angle of the cam 20. And this rocking motion is transmitted to the 2nd shaft 19-2 via the rod 24 and the transmission plate 23, and it becomes a rotational motion and rotates the 2nd shaft 19-2. Then, the 2nd arm part 16-2 attached to the 2nd shaft 19-2 rotates, and the main-body part 16b which became rotatable with respect to the said 2nd arm part 16-2 is 1st. The shaft 19-1 is rotated around the center of rotation.

  In such a structure, when the drive motor 17 is rotated (in the case shown in FIG. 5, it is rotated counterclockwise), the main body portion 16 b of the thrust roller unit 16 is lifted, and the molding mounted on the plate mounting portion 7. The plate 8 is pushed up by the protrusion 16a. Thereby, the developed molding plate 8 is bent so as to be wound, and as described above, the seaweed and cooked rice on the molding plate 8 are wound so as to wrap the ingredients to obtain the seaweed roll.

  If the seaweed roll is obtained, the main body 16b is lowered when the drive motor 17 is rotated in the opposite direction (in the case shown in FIG. 5, it is rotated clockwise). Along with this, the molded plate 8 bent so as to be wound back returns to the shape developed on the plate mounting portion 7.

  As shown in FIG. 4, the protruding frame 16 a-1 to which the protruding portion 16 a is attached is slidable back and forth with respect to the moving direction of the forming plate 8 with respect to the main body portion 16 b of the protruding roller unit 16. Yes. And it fixes to three positions with the stopper which is not illustrated. Thereby, the protrusion position with respect to the shaping | molding plate 8 of the protrusion 16a attached to the protrusion frame 16a-1 can be adjusted to three kinds.

  As described above, sushi rolls have different diameters for thick rolls, medium rolls, thin rolls, etc., and the molding plate 8 of the present embodiment also has a thick roll molding plate and medium roll molding corresponding to these. Three types of molding plates 8 are prepared: a plate and a narrow winding molding plate. Since the size of the molding plate 8 differs in the longitudinal length with respect to the moving direction of the molding plate 8, the protruding position relative to the molding plate 8 can be adjusted in three ways according to the size. It is unnecessary to replace the parts of the protrusion 16a.

  In the present embodiment, three types of molding plates 8 are assumed. However, the molding plates 8 may have different sizes, and two or four or more types of molding plates 8 are assumed. May be. In this case, the protrusion position of the protrusion 16a with respect to the forming plate 8 can be adjusted to two or four or more.

  Moreover, in this Embodiment, although the protrusion position with respect to the shaping | molding plate 8 of the protrusion upper part 16a can be adjusted, it may become impossible to adjust.

  Here, the pushing-up of the forming plate 8 by the raising roller unit 16 driven by the drive motor 17 will be described with reference to FIGS. 6 and 7 show the case where the size of the forming plate 8 and the protruding position of the protruding roller unit 16 are matched, FIG. 6 shows the state before the protrusion, and FIG. 7 shows the state after the protrusion. Each state is shown. 8 and 9 show a case where the size of the forming plate 8 and the protruding position of the protruding roller unit 16 do not match. FIG. 8 shows a state before the protruding, and FIG. 9 shows a state after the protruding. Each state is shown.

  As shown in FIG. 6, when the size of the forming plate 8 and the protruding position of the protruding roller unit 16 are matched, when the forming plate 8 is pushed up by the protruding roller unit 16, as shown in FIG. Then, the unfolded forming plate 8 is bent so as to be rolled up.

  On the other hand, as shown in FIG. 8, when the size of the forming plate 8 and the protruding position of the protruding roller unit 16 do not match, when the forming plate 8 is pushed up by the protruding roller unit 16, FIG. As shown in the figure, during the upward movement of the upward roller unit 16, the upward roller unit 16 and the forming plate 8 interfere with each other at the interference portion.

  Specifically, a plate-like member 8a-1 fixed to the plate mounting portion 7 (a plate-like member 8a-1 positioned on the inner side among a plurality of plate-like members 8a that are components of the forming plate 8) Further, the upper roller unit 16 and the forming plate 8 interfere with each other when the upper portion 16a of the upper roller unit 16 comes into contact therewith. Therefore, in this Embodiment, the plate-shaped member 8a-1 is an interference part, and the independent component as an interference part is unnecessary. This simplifies the configuration and reduces costs.

  However, it is not necessary that the plate-like member 8a-1 is an interference part, and when the size of the forming plate 8 and the protruding position of the protruding roller unit 16 do not match, the protruding roller unit 16 and the forming plate Various structures that interfere with 8 can be adopted.

  Now, in the rolled sushi manufacturing apparatus M of the present embodiment, as shown in the block diagram of FIG. 10, a rotary encoder (not shown) is attached to the motor shaft 17a of the drive motor 17, and the output of the rotary encoder. Are output to the control unit 10 described above. Thereby, the rotation angle of the drive motor 17 is detected, and the rising amount of the thrust roller unit 16 is grasped through this rotation angle. Further, a torque control output signal is outputted from the control unit 10, and the torque of the drive motor 17 is controlled by controlling the voltage applied to the drive motor 17. Details of torque control of the drive motor 17 by the control unit 10 will be described later.

  The rolled sushi manufacturing apparatus M is provided with a position sensor 25 for detecting the uppermost position of the upper roller unit 16, and the output of the position sensor 25 is input to the control unit 10, whereby the upper roller unit Whether or not 16 has reached the uppermost position is grasped.

  Further, the rolled sushi manufacturing apparatus M is provided with an alarm 26 (notification means) that issues an alarm and notifies the operator when the upper roller unit 16 and the forming plate 8 interfere with each other.

  With reference to the flowchart of FIG. 11, the ascending operation of the upper roller unit 16 controlled by the control unit 10 in the rolled sushi manufacturing apparatus M having the above structure will be described.

  First, the control unit 10 clears the encoder pulse of the drive motor 17 in a state where the upper roller unit 16 is at the lowest position so that the torque generated by the drive motor 17 becomes a small torque (first torque). The torque control voltage is controlled to turn on the output of the drive motor 17 (step S10). Thereby, the thrust roller unit 16 driven by the drive motor 17 starts to rise.

  The first torque is such a torque that the push-up roller unit 16 stops being pushed up when the push-up roller unit 16 and the forming plate 8 interfere with each other and cannot be raised further.

  Next, the control unit 10 determines whether or not the output of the drive motor 17 has been continuously output for a certain period of time (step S11). If not, the controller 10 outputs a predetermined number of encoder pulses of the drive motor 17 in advance. It is determined whether the output is greater than A (constant) (step 12). Then, if the encoder pulse of the drive motor 17 is output to a predetermined number A or more, the process proceeds to the next step S14, and if not output, the process returns to the above-described step S11.

  On the other hand, if the output of the drive motor 17 is output continuously for a predetermined time in step S11 (that is, it is determined in step S12 that the encoder pulse of the drive motor 17 is not output to a predetermined number A or more. However, if the output of the drive motor 17 is output continuously for a predetermined time after returning to step S11), the output of the drive motor 17 is turned off, that is, blocked (step S13). At the same time, the controller 10 activates the alarm 26 to generate an alarm (step S13), and reliably notifies the operator that the thrust roller unit 16 and the forming plate 8 interfered with each other.

  Note that the predetermined number A of encoder pulses is the drive motor when the upper roller unit 16 reaches a rising amount that is greater than the position where the upper roller unit 16 and the forming plate 8 interfere with each other at the interference portion (see FIG. 9). The amount of rotation is 17.

  Here, since the encoder pulse of the drive motor 17 has not been output to a predetermined number A or more in step S12, the process returns to step S11, and the output of the drive motor 17 has been output continuously for a certain time in step S11. Although the rising roller unit 16 has not risen above the position where it interferes with the forming plate 8, a time has passed to rise above the position where it interferes (cycle of the rising roller unit 16). Time over). In other words, this means that the protruding roller unit 16 and the forming plate 8 interfere with each other because the size of the forming plate 8 and the protruding position of the protruding roller unit 16 are not matched. (See FIGS. 8 and 9).

  Therefore, in the rolled sushi manufacturing apparatus M of the present embodiment, the first torque (that is, the uplift) is reached until the control unit 10 reaches a position where the uplift roller unit 16 and the forming plate 8 may interfere with each other. When the roller unit 16 and the forming plate 8 interfere with each other, the drive motor 17 is driven with a torque that is such that the push-up of the push-up roller unit 16 stops and can no longer be raised.

  As a result, when the upper roller unit 16 and the forming plate 8 interfere with each other, the upper roller unit 16 stops being pushed up and cannot be further raised, and stops without damaging the parts.

  Therefore, damage due to incompatibility between the size of the forming plate 8 and the protruding roller unit 16 can be prevented without using a sensor.

  In the present embodiment, when the two interfere with each other and the push-up of the thrust roller unit 16 stops, in step S13, the output of the drive motor 17 is turned off to suppress wasteful power consumption. However, the output may be left ON. Further, the alarm 26 for notifying that the thrust roller unit 16 and the forming plate 8 interfere with each other is not necessary.

  On the other hand, in step 12, if the encoder pulse of the drive motor 17 is output to a predetermined number A or more, the amount of increase is greater than the position where the upper roller unit 16 and the forming plate 8 interfere with each other at the interference portion. This means that the thrust roller unit 16 has arrived. In other words, this means that the protruding roller unit 16 and the forming plate 8 do not interfere with each other because the size of the forming plate 8 matches the protruding position of the protruding roller unit 16. (See FIGS. 6 and 7).

  As described above, since the apparatus is not likely to be damaged after reaching the position where the protrusion roller unit 16 and the forming plate 8 may interfere with each other, the control unit 10 performs the first torque at the start of driving. The drive motor 17 is driven with a control voltage having a larger torque (second torque), and the thrust roller unit 16 is continuously raised (step S14).

  It is sufficient that the second torque is larger than the first torque. However, since the position where the thrust roller unit 16 may interfere with the molding plate 8 is a position where there is no possibility of damage due to the interference between the two, it is desirable to raise the torque of the drive motor 17 to the maximum. It is preferable to form a seaweed roll in which the forming plate 8 is bent and wound to firmly wrap the cooked rice and ingredients.

  If the position sensor 25 is turned on in the state in which the drive roller 17 continues to raise the thrust roller unit 16 with the second torque in step S14, that is, the output of the position sensor 25 is sent to the control unit 10. If it is input (step S15), the control unit 10 turns off the output of the drive motor 17 (step S16).

  That is, as described above, since the position sensor 25 detects the uppermost position of the upper roller unit 16, the fact that the position sensor 25 is ON means that the upper roller unit 16 has reached the uppermost position, It means that the forming plate 8 is bent so as to be wound by the upper roller unit 16 and the seaweed winding is completed. At that time, the output of the drive motor 17 is turned off. As a result of such a series of operations, the raising of the thrust roller unit 16 is completed.
