It is arranged at a position in front of the rice block R. Thereafter, the solenoid PL1 is driven to close the blade of the cutter 22, thereby cutting the laver 18 (FIGS. 15P7 ', P8').
[0041]
Next, the motor M2 is driven to rotate the rotating disk 5 by one pitch in the direction of arrow C, and the hole 5a moves to the laver winding position S4 (FIG. 15P4). In this transition process, since the roller 13a "runs on the high position portion 15b of the cam 15 having the same height, the rice forming elevator 13a maintains the height of FIG. 6 (c). The rice chunk R also moves to the laver winding position S4 with the rice chunk R protruding above the rotating disk 5. Therefore, in this transition process, the rice chunk R is guided by the guide portions 23a and 23a 'of the laver guide 23. At this time, the laver 18 adheres to the front of the rice lump R in the traveling direction at this time, and the laver 18 adheres to the rice lump R reliably due to the adhesive force of the rice lump R itself. When the rotating disk 5 reaches the laver winding position S4, the rice chunk R is located at the middle of the rice chunk receiving portions 27 and 27 'as shown in Fig. 13A. First, drive the motor M4 to drive the 31 is rotated to drive the rice chunk receiving portions 27 and 27 'in directions approaching each other (the directions of arrows I and J) to wrap the rice chunk R from the left and right directions as shown in FIG. This causes the seaweed 18 to adhere to the left and right side surfaces of the rice block R. Next, the drive of the motor M4 is stopped, and the rotary solenoids PL2 and PL2 'are driven to drive the seaweed holding pieces 29 and 29'. Are rotated in directions (arrows M and N) approaching each other with the drive shafts 28 and 28 ′ as support shafts, and the laver 18 on the rear side of the rice block R is attached to the rear side of the rice block (FIG. 13C). At this time, the solenoid is driven in the order of PL2 and PL2 'to drive the laver retainer pieces 29 and 29' alternately in the order of (1) and (2) in FIG. 15P10 ′), whereby the end of the nori 18 is slightly behind the rice block R. It is stuck in a bend, and the seaweed 18 is wrapped around the rice block R, so that a so-called warship winding state is completed ((d) in the figure). Is released, the laver retainer pieces 29, 29 'rotate and return in a direction (arrows O and P directions) apart from each other by the biasing force of the spring (FIG. 13 (d), FIG. 15P11'), and the motor M4 Is driven in the opposite direction to drive the rice lump receiving portions 27 and 27 'in directions away from each other (directions of arrows K and L) (FIGS. 13 (e) and 15P12'). 5, a so-called warship roll R '(without any components) is completed.
[0042]
Next, the motor M2 is driven by one pitch, and the hole 5a moves to the unloading position S5 (FIG. 15P5). Also in this transition process, since the roller 13a "of the rice-forming elevating and lowering receiver 13a runs on the cam 15 (the high position portion 15a) having the same height, the height of FIG. 6C is maintained. Then, the rice chunk R 'moves to the unloading position S5 with the rice lump R' protruding above the rotating disk 15. Here, the worker or the like unloads the completed warship winding R 'by hand, and the warship winding R' Various materials are placed on the upper surface of the 'to complete the warship winding (FIG. 15S13').
[0043]
Next, the motor M2 is driven by one pitch, the hole 5a moves to the transition position S6 (FIG. 15P6), and the motor M2 is further driven by one pitch, so that the hole 5a returns to the rice supply position S1. Thus, one process ends (FIGS. 15P6-P1). In the process of shifting from the shift position S6 to the rice supply position S1, the roller 13a ″ moves down the descending portion 15c of the cam 15 in the rice forming elevator 13a. The receiving surface 13a 'is returned to the position shown in Fig. 6 (a) located at the back of the hole 5a.Thus, the manufacturing process of one warship winding is completed, but in practice, the rotating disk 5 Every time the pitch is rotated, the rice is sequentially supplied to each of the rice forming holes 5a at the rice supply position S1, and processing is performed one after another at the subsequent positions S2 to S6. Since the nodules R '(warship rolls) wound with laver are supplied for each pitch, the operator successively unloads the nodules R' sent to the unloading position S5.
[0044]
16 (a) to 16 (e) and FIGS. 17 (a) to 17 (e) show another embodiment of the laver winding member 24, and FIG. 16 shows a pair of substantially L-shaped members. The rice chunks R are positioned between the rice chunk receiving portions 40 and 40 '(FIG. 16 (a)). The laver 18 is adhered to both sides of the rice block R by approaching (FIG. 8B), and the shutters 41 and 41 ′ provided at the rear ends of the receiving portions 40 and 40 ′ are then moved to the same position in FIG. ) Of (1) and (2) are alternately closed, and the laver 18 is folded into the rear side surface of the rice block R and adhered to the side surface (FIG. (C)), and then the shutters 41 and 41 'are opened. Opening (FIG. (D)) and opening the rice chunk receiving portions 40 and 40 'in a direction away from each other, the warship winding R' can be completed on the rotating disk 5. .
[0045]
The one shown in FIG. 17 has concave portions 42b, 42b ′ on the surfaces facing each other, and a pair of laver winding rollers 42, 42 ′ having a substantially elliptical shape in plan view rotatable around the axes 42a, 42a ′. The rice chunk R is configured to enter the center between the rollers 42 and 42 '(FIG. 17 (a)), and then the rollers 42 and 42' are moved in a direction approaching each other to remove the nori 18 from the rice chunk. 17 (b), and by rotating the rollers 42, 42 'in the direction of arrow X, one end of the laver 18 is wound around the rice block R by one roller 42' (FIG. 17 (b)). c)) Then, the other end of the laver 18 is wound around the rice block R by the other roller 42 by rotating the rollers 42 and 42 'in the opposite direction of the arrow Y (FIG. 4 (d)). Then, the rollers 42 and 42 'are opened in a direction away from each other, so that It can be completed warships winding R 'on the rotating disk 5.
[0046]
As a method of winding the seaweed around the rice block R in the seaweed winding apparatus of the present invention, any of the methods shown in FIGS. 13, 16 and 17 may be used, or another method may be used.
[0047]
FIG. 18 shows another embodiment of the arm 25, in which one end of the arm 25 is supported on a machine frame F by a drive shaft 33, and the arm 25 is rotated in the direction of arrow Q about the drive shaft 33 as a fulcrum. It is configured so that it can be performed. In this way, after the seaweed is wound around the rice block R by the seaweed winding member 24 at the seaweed winding position S4 on the disk 5, the state of FIG. 13C (or FIG. 16C). Then, the drive shaft 33 is driven to rotate the arm 25 in the direction of arrow Q, and the above-mentioned FIGS. 13 (d) and (e) (or FIGS. By opening the laver winding member 24 in the order of (d) and (e)), the rice chunk R can be automatically taken down on the tray. It should be noted that an alignment robot arm can be attached as the arm 25, and the rice lumps R can be arranged and arranged on a tray by the robot arm, or sent to the unloading position S5 separately from the arm 25. A robot arm may be provided for gripping the rice chunk R 'and aligning it on the tray.
[0048]
As described above, according to the laver winding apparatus and method of the present invention, unlike the conventional apparatus, it is not necessary to suction the laver from the laver stocker 61, so that it is possible to prevent the production of defective products due to a suction error or the like. it can.
[0049]
Further, since the configuration is such that the laver is drawn out from the laver supply roll 17 and cut, for example, by adjusting the time T of the timer TA to adjust the timing for cutting the laver, the band laver can be cut around the rice block R. The length can be set in advance according to the length (peripheral side length), the remainder of the nori after winding the nori around the rice lump R can be minimized, and it is optimal according to the size of the rice lump R Length of nori. Accordingly, it is possible to efficiently manufacture the nori roll by eliminating waste of the nori such as excess loss of the nori and supply loss of the nori.
[0050]
In addition, since the intermittent drive rotary disk 5 can perform each process of supplying rice, forming rice chunks, supplying laver, winding laver, etc. to produce laver rolls such as warship rolls, the entire apparatus can be made extremely compact. It can be configured.
[0051]
