[0023]
First, the overall configuration and operation of the present invention will be described with reference to FIG. The present invention includes a formed rice transfer mechanism A formed on the machine frame F1, a laver supply mechanism B mainly formed on the machine frame F2, and a nori wrapping mechanism C mainly formed in the machine frame F3. Has been. In the shaped rice transfer function A, rice is supplied to the rice hopper 1, and the supplied rice is unwound by a breaker (not shown), and then is put into the rice feed hole 3 at the position K 1 of the lower rotating disk 2. Drops are supplied intermittently every fixed amount. The turntable 2 is intermittently driven every pitch (60 degrees) in the direction of arrow S1 in time with the timing of dropping the rice so that the rice supply hole 3 stops at the lower position K1 of the rice hopper 1 in sequence. As a result, a certain amount of rice is successively supplied to the rice supply hole 3 at the position K1. When the rotary disk 2 is driven for one pitch in the direction of arrow S1, the rice lump R is positioned at a position K2 immediately below the rice forming pressing tool 4, and the rice is sushi at the position K2 by the lowering operation of the pressing tool 4. It is formed into a rice shape (hereinafter, a lump of rice formed into a sushi rice shape is referred to as formed rice R). Thereafter, when the rotating disk 2 is further driven for one pitch, the formed rice R stops at the position K3. A rice forming mechanism using such a rotating disk 2 is a known technique (for example, Japanese Patent Application Laid-Open No. 2000-125788), supplies rice into the rice forming hole 3, and puts the pressing tool 4 at the position K 2. A lump of rice is formed into a sushi rice shape by inserting it into the hole 3, and then, with the rotation of the rotary plate 2, an elevating receiving tool (not shown) in the hole 3 is moved to the position K3 by the action of a cam or the like. And the formed rice R can be projected on the turntable 2 at the position K3. When the shaped rice R comes out on the rotating disk 2 at the position K3, the belt-like laver 11a is pulled out from the roll-shaped laver 11 by the driving roller 21 of the laver supply mechanism B and is moved to the front position in the transfer direction of the shaped rice R. Then, the laver 11a is cut with the laver cutter 23 (the strip-like laver after the cut is denoted as N). That is, the strip laver N is supplied to the front position of the shaped rice R (FIG. 1). A pair of front laver presses in a state where the laver wrapping mechanism C is closed by reaching the position K4 in a state where the strip laver N is in contact with the front part of the formed rice R by the next 1-pitch rotation of the turntable 2. The seaweed N is pressed against the front part of the shaped rice R by the pieces 49 and 53, and then the pair of rear seaweed holding pieces 36 and 42 are alternately closed, so that both ends N ′ and N ″ of the seaweed N are shaped. By pressing on the rear part of R, seaweed N is wound around the shaped rice R to form a warship roll (FIGS. 8A to 8C). By the rotation, the formed rice R reaches the position K5 of the rotating disk 2 and is unloaded by a robot arm (not shown) or manually.
[0024]
Next, the laver supply mechanism B will be described in detail.
(1) Nori supply mechanism B
The laver supply mechanism B is provided on a substrate F2 ′ of a machine frame F2 adjacent to the machine frame F1. Reference numeral 10 denotes a cross-shaped core member, and an annular roll laver 11 is attached to the core member 10. The core member 10 is configured to be rotatable at least in the direction of the arrow S1 ′ around the central axis 10a. The roll-shaped laver 11 is formed by connecting the end portions of a laver having a width of about 30 mm with an edible glue or the like, and is formed by winding the belt-shaped laver in an annular shape (see FIG. 9A). Reference numeral 12 denotes a seaweed drawer arm for pulling out the strip-shaped seaweed 11a from the roll-shaped seaweed 11, and a drive shaft 13 is provided at the end of the arm 12, and a roller 14 for pulling out the seaweed 11a rotates at one end of the arm 12. The shaft 15 is freely supported. The drive shaft 13 is fixed to the end of the arm 12, and the arm 12 is reciprocally rotated in the directions of arrows S2 and S3 by reciprocatingly rotating the shaft 13 in the forward and reverse directions, so that the rolled laver The strip laver 11a is pulled out from 11, and the slack portion 11b is once formed in the strip laver 11a as shown in FIG. The drive shaft 13 is concentrically provided with a rotatable guide roller 16 for guiding the strip laver 11a.
[0025]
The laver drawer arm 12 is driven by a crank mechanism shown in FIG. This figure shows a state in which the substrate F2 ′ is removed, and the end of the drive arm 17 is fixed to the drive shaft 13 below the substrate F2 ′. The drive arm 17 is provided at a position corresponding to the laver drawer arm 12. Reference numeral 18 denotes an output shaft of a drive motor M1 for driving the drive arm 17, and a rotary arm 19 extending in the horizontal direction is connected to the output shaft 18, and an upright pin 19a at the tip of the arm 19 is connected to the drive shaft. The arm 17 is engaged with the long hole 17a. Accordingly, by rotating the motor M1 at a constant speed in the direction of arrow S4 ′, the arm 19 rotates at a constant speed in the same direction, and the arm 17 moves from the solid line position L1 in FIG. 2 to the two-dot chain line position L2. Rotation (angle α) causes the drive arm 17 to rotate from the solid line position (standby position P1) in FIG. 2 in the direction of the arrow S2 to be positioned at the laver extraction position P2 indicated by a two-dot chain line in FIG. Rotation from the position L2 to the position L1 (angles β, β <α) causes the drive arm 17 to rotate in the direction of arrow S3 and return to the standby position P1. Therefore, the laver drawer arm 12 connected to the drive shaft 13 also repeatedly performs reciprocating rotation operation from the standby position P1 to the laver drawer position P2 along with the drive arm 17.
[0026]
Further, the laver drawer arm 12 moves from the standby position P1 to the laver drawer position P2 by the rotation of the angle (α) of the position L1 to L2 of the rotary arm 19 rotating at a constant speed, and the angle of the positions L2 to L1. Since the rotation of (β, β <α) returns from the nori extraction position P2 to the standby position P1, the rotation speed of the nori extraction arm 12 is low-speed movement in the arrow S2 direction and the rotation in the arrow S3 direction. Movement return is high-speed movement.
[0027]
20 is a rotatable guide roller provided on the rotating disk 2 side adjacent to the driving shaft 13, 21 is a driving roller for pulling out the strip laver 11 a in the direction of the rotating disk 2, and 22 is in pressure contact with the driving roller 21. A belt-like laver 11a, which is a rotatable pressure roller, located between the driving roller 21 and the pressure roller 22, is driven in the direction of the rotary disk 2 (arrow S5 direction) by intermittent rotation driving of the driving roller 21 in the arrow S4 direction. It is something to pull out. That is, the laver 11a having a length substantially corresponding to a slack drawn from the laver roll 11 as a slack portion 11b is drawn out and supplied by the driving roller 21. The end of the drawn laver 11a reaches the vicinity of the central axis of the rotating disk 2 (position a in FIG. 1), and the laver 11a (N) is placed at a front position in the transfer direction of the formed rice R that has arrived at the position K3. Suppose that it is supplied upright with respect to the upper surface of the turntable 2. That is, the drive roller 21 rotates at the timing when the laver presser arm 12 rotates in the direction of arrow S2 to pull out the band-like laver 11a to form a slack portion 11b, and then the arm 12 returns to rotate in the direction of arrow S3. The belt-like laver 11a is rotated for a certain time (or a certain angle) and supplied to the front position of the shaped rice R. M2 is a drive motor that intermittently drives the drive roller 21.
[0028]
Reference numeral 23 denotes a laver cutter provided between the drive roller 21 and the rotating disk 2, and the cutter 23 is provided on the machine frame F3. The laver cutter 23 is driven by the drive plunger P (FIG. 4) at a timing immediately after the belt-like laver 11a is pulled out by the drive roller 21, and cuts the belt-like laver 11a at a position b shown in FIG. . As a result, one strip of laver N (length ab) is supplied to the front position of the shaped rice R. In addition, G in FIG. 1 is a guide guide which guides laver to the front position of the formed rice.
[0029]
Since the seaweed supply mechanism B is configured as described above, the operation of the mechanism B will be described next. First, an annular roll-shaped laver 11 is mounted on the core member 10, the strip-shaped laver 11a is passed from the outside of the guide roller 14 through the inside of the guide roller 16 to the outside of the guide roller 20, and the strip-like laver 11a is further pressed against the pressure roller. A tip part is protruded from both rollers 21 and 22 through between 22 and the drive roller 21 a little. In this state, when the operation of the mechanism B is started, the drive motor M1 rotates at a constant speed, and the nori extraction arm 12 is extracted from the standby position P1 in the arrow S2 direction by the rotation of the arm 19 in the arrow S4 ′ direction. By rotating to the position P2 (FIG. 3) and further returning from the position P2 to the standby position P1 (FIG. 4), the strip laver 11a is pulled out as shown in FIG. 4 and a slack portion 11b is formed. . When the drive motor M2 is driven for a certain period of time at a timing immediately after the slack part 11b is formed, the drive roller 21 rotates for a certain period of time, whereby the strip laver 11a of the slack part 11b is rotated in the direction of arrow S5, that is, rotated. It is pulled out in the direction of the board 2 until its tip reaches a position a. The drawing operation of the laver 11a is performed at the timing when the shaped rice R of the rotating disk 2 arrives at the position K3 and stops at the position K3. Accordingly, the drawn strip laver 11a is positioned in front of the shaped rice R that has arrived at the position K3 of the rotating disk 2 (the state shown in FIG. 8A). Thereafter, the cutter 23 is driven by the plunger P, and the strip laver 11a is cut at the position b. When the turntable 2 is driven by one pitch at a later timing, the shaped rice R rotates in the direction of the arrow S1, and the belt-like laver N sticks to the front side surface of the shaped rice R by the rotation, In the state shown in FIG. 8B, the formed rice R reaches the position K4. Since the drive motor M1 is continuously rotated, the laver drawer arm 12 repeats a reciprocating rotation operation that subsequently returns from the standby position P1 to the standby position P1 via the laver extraction position P2, thereby loosening the slack portion. 11b are sequentially formed, and at the timing immediately after the slack portion 11b is formed, the driving roller 21 rotates to supply the belt-shaped laver 11a having a predetermined length to the front position of the shaped rice R, and the plunger P is driven to drive the laver. Cut 11a.
[0030]
Thereafter, the above-described operation is repeated according to the timing at which the formed rice R arrives at the position K3 by intermittent rotation of the turntable 2. Thereby, the strip-like laver N is sequentially supplied from the roll-like laver 11 to the front position in the transfer direction of the formed rice R that sequentially arrives at the position K3 of the rotating disk 2.
[0031]
FIG. 10 shows another embodiment of the laver supply mechanism B. In place of the laver extract arm 12, the mechanism B is provided with a laver extract roller 60 that comes into contact with the outer peripheral side surface of the roll-shaped laver 11, and the roller 60 is intermittently driven in the direction of the arrow S1 ", whereby the roll The strip-shaped laver 11a is drawn out from the lamellar laver 11 to form a slack portion 11b, wherein the roller 60 is always pressed against the outer peripheral side surface of the rolled laver 11 by a biasing means such as a spring (not shown). If comprised in this way, since the force of a tension | pulling direction (arrow F direction in FIG. 10) does not act on the strip | belt-shaped seaweed 11a pulled out from the roll-shaped seaweed 11, the cutting | disconnection by the tension | pulling of the strip | belt-shaped seaweed 11a will be prevented, and a strip | belt shape will be smooth. The laver 11a can be pulled out, and the other configuration is the same as that of the supply mechanism B in FIG.
[0032]
(2) Nori winding mechanism C
Next, the seaweed winding mechanism C will be described with reference to FIGS. In the mechanism C, three cams (first cam 31 (FIG. 5A)), second cam 37 (FIG. 5A), and third cam 43 are formed on the upright drive shaft 30 from the bottom to the top. (FIG. 5 (b)) is fixedly provided, and the cam 30 is simultaneously driven to rotate by driving the drive shaft 30 at a constant speed in the direction of arrow S6 by the drive motor M3. The pieces 49 and 53 (FIG. 5B) and the rear laver press pieces 36 and 42 (FIG. 5A) are driven to open and close.
[0033]
The first cam 31 is fixed to the lowest part of the upright drive shaft 30, and the cam receiving shaft 32 a of the drive arm 32 is in contact with the first surface 31 a of the cam 31. The drive arm 32 is rotatable about its support shaft 33, and when the cam receiving shaft 32 a comes into contact with the second surface 31 b of the cam 31 by the rotation of the cam 31, the drive arm 32. Rotates around the support shaft 33 in the direction of the arrow S7, and a drive piece 35 supported by the piece 34 via a connection piece 34 supported by the tip of the arm 32 is attached to the support shaft 35 '. To rotate in the direction of arrow S8. As a result, the left pressing piece 36 fixed to the driving piece 35 is rotationally driven in the direction of the arrow S9 from the opened state in FIG. 5A, and is rotationally driven to the closed state shown in FIG. 6C. It is. Since the first cam 31 continuously rotates in the direction of arrow S6, the first surface 31a of the cam 31 comes into contact with the cam receiving shaft 32a again, so that the drive arm 32 is in the direction opposite to that of the arrow S7. The holding piece 36 returns to the solid line position (open state) in FIG. Accordingly, the pressing piece 36 repeatedly opens and closes as the first cam 31 rotates continuously.

It is rotationally driven in the direction of arrow S10 with '. As a result, the right pressing piece 42 fixed to the driving piece 41 is rotationally driven in the direction of arrow S11 from the open state shown in FIG. 5A to the closed state shown in FIG. 6C. Since the second cam 37 continuously rotates in the direction of the arrow S6, the first surface 37a of the cam 37 comes into contact with the cam receiving shaft 38a again, so that the drive arm 38 is opposite to the arrow S20. The pressing piece 42 returns to the solid line position (open state) in FIG. 5A. Accordingly, as the second cam 37 rotates continuously, the holding piece 42 repeatedly opens and closes. In addition, since the first surface 37a of the second cam 37 is formed wider than the first surface 31a of the first cam 31, the cam receiving shaft 32a is preceded by the rotation of the drive shaft 30. Since the cam bearing shaft 38a comes into contact with the second surface 37b of the second cam 37 after that, the left pressing piece 36 is first moved to the arrow S9. The right pressing piece 42 is rotated in the direction of the arrow S11 thereafter. In this way, the pressing pieces 36 and 42 are alternately closed at different timings so that the end portion N ′ of the strip-shaped laver N is first attached to the rear side surface of the shaped rice R, and then the end portion N ″ is the same. It is comprised so that it can stick to a side surface, and it has comprised so that the edge part N ', N "of seaweed may overlap and overlap in the rear part of the shaping | molding rice R (overlapping part Q) (FIG. 8 (c)).

It rotates in the direction of arrow S13 around the support shaft 48. The base end portion of the right pressing piece 49 is fixed to the support shaft 48 of the rotating piece 47, and the holding piece 49 is moved from the open state of FIG. Rotating in the direction of arrow S14, the closed state shown in FIG.
[0036]
Further, one end of a connection arm 50 is pivotally supported on the pivot piece 47, and a pivot piece 51 pivotally supported on a pivot shaft 52 is pivotally supported on the other end of the arm 50. Accordingly, the connection arm 50 moves in the direction of arrow S15 by the rotation of the rotation piece 47 in the direction of arrow S13, thereby rotating the rotation piece 51 in the direction of arrow S16 about the support shaft 52, The left pressing piece 53 fixed to the support shaft 52 is rotated in the direction of arrow S17 from the open state in FIG. 5B to the closed state in FIG. 6C.
[0037]
Then, when the cam shaft 44a is in contact with the second surface 43b by the rotation of the drive shaft 30, the pressing pieces 49 and 53 are kept closed, and the cam shaft 44a is in contact with the second shaft 43a. When the first surface 43a is positioned, the drive arm 44 is rotated and returned again in the direction opposite to the arrow S12, whereby the pressing pieces 49 and 53 are opened as shown in FIG. Therefore, by the continuous rotation of the drive shaft 30, the pressing pieces 49 and 53 repeatedly open and close. As shown in FIG. 5A, the drive shaft 30 is driven by connecting a drive motor M3 to the drive shaft 30 via a belt and driving the drive shaft 30 in the direction of arrow S6. The seaweed winding mechanism C is provided in the machine frame F3, and the presser pieces 36, 42, 49, 53 are suspended and supported downward from the machine frame F3. Further, the cam receiving shafts 32a, 38a, 44a are connected to the corresponding cams 31, 37, 43 so that the cam arms 32, 38, 44 can always be kept in pressure contact with the corresponding cams 31, 37, 43, respectively.

[0038]
(3) About the seaweed presser piece (see Fig. 7)
Next, the shape of the front and rear laver press pieces 36, 42, 49, 53 will be described. These holding pieces are formed by bending a plate member having a predetermined width, and the holding pieces 49 and 53 on the front side move with base portions 49a and 53a fixed to the support shafts 48 and 52, respectively. In the closed state shown in FIG. 6 (c), the bent portions 49b and 53b along the front side corner of the formed rice R and the flat pressing portions 49c and 53c that press the laver on the front side of the rice R. The seaweed N is stuck around the front side in contact with the front side surface and the front corner of the shaped rice R (FIG. 8C). L-shaped pressing pieces 49d and 53d having protrusions 49d'53d 'orthogonal to the surfaces of the pressing portions 49c and 53c are fixed inside the bent portions 49b and 53b. In the closed state of the pieces 49, 53, the projecting portions 49d ′, 53d ′ are in contact with the left and right side surfaces of the shaped rice R, so that the laver N can be reliably brought into contact with the left and right side surfaces. After the seaweed N is wound, the formed rice R moves to the position K5 by the rotation of the turntable 2 in the open state shown in FIG. 5B. At this time, the formed rice R does not contact the left pressing piece 53. The pressing portion 53c of the left pressing piece 53 is formed shorter than the pressing portion 49c of the right pressing piece.
[0039]
The rear holding pieces 36 and 42 are formed by bending a plate-like member having a predetermined width, and after the bases 36a and 42a fixed to the rotating pieces 35 and 41, respectively, It consists of bent portions 36b, 42b along the side corners and flat plate-shaped pressing portions 36c, 42c that press the laver N on the rear surface of the shaped rice R, and in the closed state shown in FIG. The laver N is pressed around the rear surface side. The pressing portions 36c and 42c are formed as inclined surfaces that incline inwardly from the vicinity of the end portions of the bent portions 36b and 42b (in the direction of the rear side of the formed rice R) in the closed state (FIGS. 7 and 6C). Thus, the tip portions of the pressing portions 36c and 42c are surely brought into contact with the shaped rice R, and the end portions N ′ and N ″ of the laver N are reliably pressed against the rear surface of the shaped rice R by the respective leading end portions. It is formed so that can be reliably stuck (refer FIG.8 (c)).
[0040]
The laver wrapping mechanism C according to the present invention is configured as described above. Next, the operation of the mechanism C will be described. When driving of the drive motor M3 is started, the pressing pieces 36, 42, 49, 53 repeatedly open and close. At this time, when the formed rice R on the rotating disk 2 reaches the position K4, the rear pressing pieces 49 and 53 are closed, and the front pressing pieces 36 and 42 are opened (the state shown in FIG. 6B). Thereafter, the rear pressing pieces 36 and 42 are closed (the state shown in FIG. 6C), and the front and rear pressing pieces 36, 42, 49, and 53 are opened (the state shown in FIG. 6A). This is performed at the timing when the rotating disk 2 is rotated by 1 pitch and the formed rice R on which the seaweed N is wound is transferred to the position K5. Thereafter, the above operation is repeatedly performed by the rotation of the drive shaft 30.
[0041]
Nori N is supplied to the front position of the formed rice R (position K3) by the nori supply mechanism B (the state shown in FIG. 8A), and then the front part of the formed rice R is driven by 1 pitch of the rotating plate 2. In the state where the seaweed N is in contact with the side surface and the shaped rice R has reached the position K4, the front portion of the shaped rice R is in contact with the front pressing pieces 49, 53 in the closed state (FIG. 6B), The seaweed N is pressed against the front side surface and the front corner of the shaped rice R, and the seaweed N adheres to the front part (state shown in FIG. 8B).
[0042]
With the subsequent rotation of the drive shaft 30, the cam receiving shaft 32a comes into contact with the second surface 31b of the first cam 31, whereby the rear left pressing piece 36 first starts to rotate in the direction of arrow S9. Thereafter, when the cam receiving shaft 38a comes into contact with the second surface 37b of the second cam 37, the rear right pressing piece 42 starts to rotate in the arrow S11 direction, and the pressing pieces 36, 37 are rotated by the rotation of the cams 31, 37. As shown in FIG. 6 (c), 42 abuts on the rear side surface of the shaped rice R, and wraps the strip laver N around the rear surface of the shaped rice R (state of FIG. 8 (c)). At this time, the front ends of the pressing pieces 36 and 42 slightly bite into the rear side surface of the formed rice R (FIG. 6C), thereby ensuring that the end portions N ′ and N ″ of the strip laver N 6A to 6C, the cam receiving shaft 44a is kept in contact with the second surface 43b of the third cam 43 in the process of shifting from FIG. Therefore, the front pressing pieces 49 and 53 remain closed, so that the belt-like seaweed N can be reliably wound around the shaped rice R at the timing shown in FIG.
[0043]
Thereafter, by the subsequent rotation of the drive shaft 30, the first surfaces 31 a and 37 a of the first and second cams 31 and 37 abut against the cam bearings 32 a and 38 a, respectively. Are rotated in the opposite direction to the arrows S9 and S11 to be in the open state, and at the same time, the cam receiving shaft 44a is in contact with the first surface 43a of the third cam 43, so that the front pressing pieces 49 and 53 are also in the open state. (FIG. 6 (a)), at the timing when the front and rear pressing pieces 49, 53, 36, 42 are in the open state (state of FIG. 6 (a)), the rotating disk 2 is driven by 1 pitch, and nori N Is moved to position K5. Therefore, the formed rice R moved to the position K5 can be taken out. Thereafter, the above-mentioned opening / closing operation is repeated, and the strip-shaped laver N is wound around the formed rice R that sequentially reaches the position K4.
[0044]
As described above, according to the present invention, the strip-shaped laver 11a having a certain length is pulled out from the roll-shaped laver 11, and the pulled laver 11a is cut after being supplied to the front of the formed rice R. Compared with the supply of laver for each sheet, waste of laver can be reduced as much as possible, and the efficiency of laver supply can be improved. In addition, it is possible to reduce the occurrence rate of defective products by eliminating the supply mistake of nori as in the past.
[0045]
Further, when the belt-like seaweed 11a is drawn out from the roll-like seaweed 11 and the belt-like seaweed 11a is supplied to the shaped rice R, a slack portion 11b is once formed in the belt-like seaweed 11a, and the belt-like seaweed of the slackness portion 11b is substantially loosened. 11a can be supplied to the shaped rice R so that the strip laver 11a can be smoothly drawn out and supplied sequentially without directly applying the pulling force in the pulling direction to the strip laver 11a. Can be prevented.
[0046]
Further, the laver 11a can be smoothly drawn out from the roll-shaped laver 11 by the reciprocating rotation of the laver-drawing arm 12, and the slack portion 11b can be formed.
[0047]
Moreover, by using the laver drawing roll 60, the laver can be pulled out without causing a tensile force to act on the lamellar laver 11a, and cutting of the lamellar laver 11a can be prevented.
[0048]
Further, since the pressing portions 36c, 42c of the rear laver press pieces 36, 42 are provided to be inclined in the rear side surface direction of the shaped rice R, the end portions N ′, N ″ of the strip-shaped laver N are formed on the rear side surface of the shaped rice R. Can be securely attached.
[0049]
In addition, since the front and rear laver press pieces 49, 53, 36, and 42 are configured to be opened and closed by a single drive shaft 30, the drive mechanism of the press pieces can be easily configured, and the entire apparatus is downsized. can do.
[0050]
In addition, since the formed rice transfer mechanism A is configured by the rotating disk 2 or the like, and is configured to perform all the operations of supplying rice, forming rice, supplying seaweed, and winding nori on the rotating disk 2, There exists an effect that the whole apparatus can be comprised extremely small.
[0051]
【The invention's effect】
As described above, according to the present invention, unlike the conventional apparatus, it is not necessary to suck the seaweed from the seaweed stocker, and therefore it is possible to prevent the production of defective products due to a suction mistake or the like.
[0052]
In addition, the strip-shaped laver is pulled out from the roll-shaped laver to form a slack portion of the laver, and it is configured to be able to supply a labyrinth portion of the slack, so that cutting of the laver associated with the withdrawal of the lamellar laver can be prevented, The striped laver can be supplied smoothly.
[0053]
