Japanese Patent Laid-Open No. 10-304834

  However, the conventional laver winding forming mechanism winds the sheet-like seaweed around the formed cooked rice that has been conveyed in a long straight line by the intermittent conveying conveyor belt, so that the entire apparatus becomes larger depending on the length of the conveying path. . Moreover, since the shaped cooked rice itself is simply placed on the upper surface of the intermittent conveyer belt, it is difficult to place the shaped cooked rice firmly on the intermittent conveyer belt, and the sheet-like seaweed is stably maintained. There is a risk that winding cannot be performed and a winding mistake may occur.

  In addition, in the conventional laver winding forming mechanism, a total of four of the pair of front clampers and the pair of rear clampers are closed or opened by four clamper turning levers and four solenoids, respectively, so that the structure is complicated. Moreover, the operation is complicated.

  Therefore, the present invention was created in view of the conventional circumstances as described above, and the sheet-like seaweed is wound in a stable state with the formed cooked rice placed in place, so that the work can be smoothly performed and winding mistakes are eliminated. Another object of the present invention is to provide a laver winding forming mechanism for an automated laver winding apparatus which can simplify the winding operation of the sheet-like laver by simplifying the structure.

  In order to solve the above-mentioned problems, in the present invention, sheet-like laver that has been cut to the required dimensions in advance from the laver hopper is taken out one by one with an adsorption pad, and this is fed with a cooked rice using a feeding mechanism. The sheet-like seaweed is wound around the formed cooked rice that is supplied to the section side and conveyed by the turntable on the supply section side, and is provided with a molded lower mold that places the formed cooked rice on the upper surface of the turntable. is there.

  A nail-like presser part that holds both sides of the shaped cooked rice placed on the molding lower mold may be formed at both ends of the molding lower mold.

  A pair of clampers that are attached to each of a pair of support shafts from above the turntable and that rotate along the outer periphery of the molded lower mold formed on the upper surface of the turntable so that sheet-like seaweed is wound around both sides of the formed cooked rice, and the turntable And a rear presser plate that is swingable so as to press the rear side of the cooked cooked rice together with the sheet-like seaweed.

  The clamper includes a first swing link that is pivotably connected at one end via a pulley that is integral with the support shaft, and a second swing link that is swingably connected to the other end of the first swing link. A lever that has one end connected to the other end of the moving link and the second swing link, is rotatable around an intermediate support shaft, and is urged to rotate so that the clamper itself is in an open state; And a winding drive cam capable of intermittent rotation, in which a cam follower formed at the other end is pressed against the lever itself by the rotation bias of the lever.

  The rear presser plate is swingable via an arm portion attached to the support shaft, and an endless belt in which a pulley integrated with the support shaft and a pulley of one clamper are wound around each. By connecting them through the rear press plate, the rear presser plate and one of the clampers can be rotated together.

  In the laver winding forming mechanism of the laver winding apparatus according to the present invention configured as described above, the lower mold on the upper surface of the turntable, and the claw-shaped presser portions formed on both sides of the lower mold are formed on the turntable. The stationary stability of the shaped cooked rice is ensured, and the misalignment of the shaped cooked rice and the accompanying winding mistake of the sheeted laver are prevented in advance when the sheeted seaweed is wound around the shaped cooked rice.

  One clamper and rear presser plate that are linked to each other via endless belts wound around each pulley are centered on the respective support shafts through the movement of the lever accompanying the rotation of the winding drive cam and the linkage of the endless belts. At the same time, it is rotated in the closing direction, and at the same time as the formed rice is pressed together with the sheet-like seaweed by the back press plate, one clamper winds the sheet-like seaweed on one side.

  Further, the other clamper rotates in the closing direction around the support shaft by the operation of the lever accompanying the further rotation of the winding drive cam, and the sheet-like seaweed is wound around the other side of the formed cooked rice.

  According to the present invention, it is possible to wind the sheet-like seaweed in a stable state with the formed cooked rice placed in place, to perform the work smoothly and to eliminate winding mistakes, and to make the structure small and simple. The sheet-like seaweed winding operation can be performed simply.

  That is, this is because the present invention takes out sheet-like laver that has been cut to the required dimensions in advance from the laver hopper, one by one with an adsorption pad, and supplies it to the supply part side of the formed cooked rice with a feeding mechanism, This is because the sheet-like seaweed is wrapped around the formed cooked rice conveyed by the turntable on the supply unit side, and the turntable upper surface is provided with a molded lower mold for placing the formed cooked rice. The sheet-like seaweed can be easily wound while being fixed, so that the work can be performed smoothly and winding mistakes can be eliminated.

  At both ends of the lower mold, there are claw-shaped pressers that hold both sides of the shaped cooked rice placed on the molded lower mold. Thus, the sheet-like seaweed can be smoothly wound around the formed cooked rice without winding mistakes.

  A pair of clampers that are attached to each of a pair of support shafts from above the turntable and that rotate along the outer periphery of the molded lower mold formed on the upper surface of the turntable so that sheet-like seaweed is wound around both sides of the formed cooked rice, and the turntable It is attached to the support shaft from above, and has a rear presser plate that can be swung so that the rear side of the cooked cooked rice is pressed together with the sheet-like seaweed. Thus, the structure itself is simplified, and the sheet-shaped laver can be simply wound, and the sheet-like laver can be neatly wound without breaking the shape of the formed cooked rice.

  The clamper includes a first swing link that is pivotably connected at one end via a pulley that is integral with the support shaft, and a second swing link that is swingably connected to the other end of the first swing link. A lever that has one end connected to the other end of the moving link and the second swing link, is rotatable around an intermediate support shaft, and is urged to rotate so that the clamper itself is in an open state; Since the cam follower formed on the other end of the lever is provided with a winding drive cam capable of intermittent rotation that is brought into pressure contact with the rotation bias of the insulator itself, a simplified small laver winding forming mechanism can be easily provided. .

  The rear presser plate is swingable via an arm portion attached to the support shaft, and an endless belt in which a pulley integrated with the support shaft and a pulley of one clamper are wound around each. In this way, the back presser plate and one of the clampers are rotated in conjunction with each other.Therefore, the operation of pressing the formed cooked rice together with the sheet-like seaweed with the back-holding plate, and one clamper holds the sheet-like seaweed. The operation of winding on one side is performed substantially simultaneously, and the sheet-like seaweed can be smoothly wound in a stable state.

At this time, the driven roller 10 is fixed to one end of the swing arm 12 in a non-rotatable state on the support shaft 11 connected to the rotation drive source and extending upward from the base 5, and the other end of the swing arm 12. The follower roller 10 is pivotally mounted so as to be reciprocally swingable between a position where it is pressed against the drive roller 9 and a position where it is separated.

  Next, the use and operation of the above-described configuration will be described. First, in the sheet-like nori adsorption mechanism 1, as shown in FIG. 9, a plurality of sheet-like shapes that have been cut into necessary dimensions in the nori hopper 2 in advance. The seaweed Q is accommodated so that the smooth surface side is in a laterally vertical state with the opening 2A facing the opening 2A side, and a plurality of sheet-like seaweed Q is pressed into the stopper piece 2E by pressing the sheet-like seaweed presser 2D from the rear. Lock it with. When the rotary drive source is operated and the four-joint parallel link mechanism P is turned, the suction pad 3 moves in the contact / separation direction with respect to the sheet-like seaweed extraction opening 2A of the laver hopper 2.

  At this time, as shown in FIGS. 10 and 11, when the suction pad 3 comes close to the opening 2A by the turning movement of the pair of turning link arms 7 and 7 of the four-node parallel link mechanism P, the base 5 Since the air is sucked from the suction port 5 </ b> A through the cavity S of the adsorption pad 3, the sheet-like seaweed Q is adsorbed to the adsorption pad 3.

  As shown in FIG. 12 (a), when the pair of revolving link arms 7 and 7 of the 4-node parallel link mechanism P are further swung and the suction pad 3 moves away from the opening 2A of the laver hopper 2, One end of the sheet-like seaweed Q adsorbed by the adsorption pad 3 is received by the drive roller 9.

  At the same time, as shown in FIG. 12 (b), the driven roller 10 is rotationally pressed against the driving roller 9 via the swing arm 12, and the sheet-like laver Q between the driving roller 9 and the driven roller 10. Insert one end of

  And as shown in FIG.12 (c), the drive roller 9 rotationally drives and supplies the sheet-like seaweed Q to the supply part side of the shaping cooked rice R. FIG. At this time, the intake port cover 8 always closes the intake port 5A of the base 5 while maintaining communication with the cavity S over the swivel movement range of the suction pad 3, thereby preventing leakage of the intake air from the intake port 5A. ing.

  Next, in the laver roll forming mechanism 41, as shown in FIGS. 3 and 13, the sheet-like laver Q is supplied to the front side of the formed cooked rice R placed on the lower mold 22 on the upper surface of the turntable 21. . At this time, each of the pair of clampers 23 and 23 and the rear presser plate 27 is waiting in an open state.

  As shown in FIG. 14, when the turntable 21 rotates 60 °, the formed cooked rice R and the sheet-like seaweed Q move to the position of the winding part. At this time, as shown in FIG. 4, the winding drive cam 31 rotates about 105 °, and this convex portion presses the cam follower 30 </ b> B against the rotational biasing force of the right side lever 30 to rotate the lever 30. The right clamper 23 rotates in the closing direction via the second swing link 29B and the first swing link 29A. At this time, since the rear presser plate 27 and the right clamper 23 are interlocked via the endless belt 37, the rear presser plate 27 also rotates in the closing direction simultaneously with the rotation of the right clamper 23.

  As shown in FIG. 15 (a), the right clamper 23 and the rear presser plate 27 are simultaneously rotated about the support shafts 24 and 25, respectively, so that the formed cooked rice R is pressed together with the sheet-like seaweed Q by the rear presser plate 27. The right clamper 23 winds the sheet-like seaweed Q around the right side.

  As shown in FIG. 5, when the winding drive cam 31 further rotates intermittently by 60 ° to the position of about 165 °, this convex portion presses the cam follower 30B against the rotational biasing force of the left side lever 30 to press the lever 30 , And the left clamper 23 rotates in the closing direction via the second swing link 29B and the first swing link 29A. At this time, as shown in FIG. 15 (b), the left clamper 23 rotates around the support shaft 24, so the sheet-like seaweed Q is wound around the left side of the formed cooked rice R.

  Then, as shown in FIG. 6, when the winding drive cam 31 further rotates intermittently to a position of about 300 °, the convex portion is separated from the cam follower 30 </ b> B of the lever 30 and leaves the lever 30 to the rotational biasing force of the lever 30. The right clamper 23 is rotated in the opening direction through the second swing link 29B and the first swing link 29A. At this time, since the rear presser plate 27 and the right clamper 23 are linked via the endless belt 37, the rear presser plate 27 also rotates in the opening direction simultaneously with the rotation of the right clamper 23. In this way, as shown in FIG. 15C, the right clamper 23 and the rear presser plate 27 are simultaneously opened.

  As shown in FIG. 7, when the winding drive cam 31 is rotated to the 360 ° position, the convex portion is separated from the cam follower 30B of the lever 30, and the lever 30 is rotated by the rotation biasing force to rotate the lever 30 in the opposite direction. The left clamper 23 rotates in the opening direction via the second swing link 29B and the first swing link 29A. For this reason, the left clamper 23 opens with a delay. In this way, the pair of clampers 23 and 23 and the back pressing plate 27 are restored to the initial state, and the winding drive cam 31 itself is temporarily stopped. Thereafter, the shaped cooked rice R wound with the sheet-like seaweed Q is discharged from the turntable 21 as a finished product.
