Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a completely new device for automatically forming Inari sushi, which is made by surrounding sushi rice with fried skin.

Traditionally, Inari sushi was made by hand, with chefs expanding the fried skin and filling it with sushi rice.

On the other hand, in recent years, Inari sushi has come to be sold in large quantities in packs, etc., so there has been a demand for it to be provided to the market more efficiently than if it were made by hand.

This invention was made in view of these circumstances, and is a completely new automatic forming device that can sequentially perform the various processes necessary for producing Inari sushi on a circular path around a turntable. This is what we are trying to provide.

The present invention will be described below with reference to illustrated embodiments.

A fixed frame 4a having a U-shape in plan view is installed at the rising portions of b, 3c, and 3d.
, 4b, 4c, and 4d are fixed to the turntable 1 so as to protrude in the radial direction.

The above-mentioned mounting brackets 3a, 3b, 3c, and 3d have elongated holes 5a, 3b, 3c, and 3d formed therein.
It is fixed to the turntable 1 by tightening the bolts 6a, 6bt6c, 6ci that pass through the turntable 1.
By loosening c, 6d, each fixed frame 4a, 4b,
4c and 4ci can be easily adjusted so that they all move on the same circular path.

Next, support metal fittings 7a and 7b in a dogleg shape and an inverted dogwood shape are arranged symmetrically and opposite to each other at the top of the tip of the fixed frame 4a, and this pair of support metal fittings 7a.

7b holds the open top edge of the sushi rice container 8 which is in the shape of a rhombic pyramid and has an open top.

This sushi rice container 8 has four triangular soft leaf springs 8at8b, 8c, and 8a arranged in the shape of a rhombic pyramid with an open top. Their elasticity maintains the diamond-pyramidal natural state.

Further, as shown in FIGS. 2 and 4, triangular soft leaf spring materials 8s and 8b forming the sushi rice container 8

On the outer surface side of 8d, a set of two tongue pieces 9at9b,
9ct9a is arranged, and these tongue pieces 9a t9b, 9
A pair of rotation shafts 10a, each set of c and 9d being disposed symmetrically opposite to the fixed frame 4a.

10b separately.

The rotating shafts 10a, 10b are horizontally supported by bearings 11a, 11a, 11b, 11b provided on the fixed frame 4a, as shown in FIGS. 5 and 6. , whose proximal ends are each bent link 1
Each swing center Pa of a pair of swing links 12a and 12b forming 2.

Fixed to pb.

In this case, the folded link 12 includes each swinging link 12a,
These pair of swinging links 12a are connected by the pin 14 through the elongated hole 13a>13b formed at the swinging end of the swinging link 12b.
, 12b are connected to each other, and its expansion/contraction function enables bending displacement between an upper position and a lower position that are symmetrical to each other via the axis l connecting the two swing centers.

Moreover, one swinging link 12a of the folded link 12 is
A long hole 15 is formed in the buried end thereof, and a shaft support is provided in the long hole 15 near the outside of the swing center Pb of the other swing link 12b. The free end of the actuating link 16 that has been moved is engaged via the pin 17.

Note that 18 connects the base end of the operating link 160 to the fixed frame 4a.
This is a support shaft for supporting on the side.

The operating link 16 is always urged downward by a spring 19 disposed between the operating link 16 and the fixed frame 4a, and a cam follower support rod 20 is vertically disposed at the longitudinal center of the operating link 16 via a support shaft 21.

On the other hand, as is clear from FIG. 2, FIG. 4, and FIG.
A cam base 22 with a larger diameter is fixedly arranged concentrically, and a chevron-shaped cam plate 23 having an arcuate shape in plan view is disposed over a part of the outer circumferential portion of the cam base 22, specifically, over a range of approximately -, Corresponding to the cam surface 23a of the chevron-shaped cam plate 23, a cam follower 2 is attached to the lower end of the cam 7 and the lower support rod 20.
4 is supported.

Reference numeral 25 indicates a manually operated safety lever, in which a long hole 26 formed in the middle part is engaged with a locking pin 27 protruding from the fixed frame 4a, and the tip part thereof is pivotally supported by the lower end support shaft 28 of the cam follower support rod 20.

In the above configuration, the cam mechanism 29 is constituted by the cam surface 23a of the chevron-shaped cam plate 23 and the cam follower 24, while the operating link 16, the bent link 12, the pair of rotating shafts 10a>10b, and the spring 19. A link mechanism 30 is constructed, and both mechanisms 29 and 30 are connected by a cam follower support rod 20.

Therefore, as shown in FIGS. 5 and 6, when the fixed frame 4a moves in the direction shown by the arrow X in FIG. 22 moves in the direction indicated by arrow Y in FIG. Therefore, the cam follower 24 provided at the lower end of the cam follower support rod 20 is attached to the upper surface 22 of the cam base 22.
a or the cam surface 23a and is made to follow this.

In this case, although the cam follower support rod 20 is swingably mounted vertically on the operating link 16 by the support shaft 21, the cam follower 24 and the cam base upper surface 22a or the cam surface 23
a, and the locking pin 27 is engaged with the front wall portion 26a of the elongated hole 26 in the safety lever 25 in the moving direction;
It is maintained vertically by this.

As shown by the solid line in FIGS. 5 and 6, while the cam follower 24 is following the top surface 22a of the cam base, the operating link 16 is maintained in a swinging state to the lower limit, so that the bending link 12 is held above the axis 1, and therefore the tongues 9a, 9b, 9c, 9a fixed to the rotating shaft 10at10b are in a closed state and are elastically pressed against the outer surface of the sushi rice container 8.

On the other hand, while the cam follower 24 is following the cam surface 23a, the operating link 16 is pushed up against the bias of the spring 19 and remains oscillated to its upper limit,
As a result, the extending end of one swing link 12a is pushed up above the axis 1 via the pin 17, as shown by the imaginary line in FIG. 1 and is therefore fixed to the pivot shafts 10a, 10b.

9 b , 9 c > 9 b are these rotation axes 10 a
.

As 10b rotates, it becomes open, and the sushi rice container 8
separated from the outer surface of

Furthermore, if the safety lever 25 is pulled in the direction of movement while the cam follower 24 is following the cam surface 23a, the cam follower support rod 20 will move against the support shaft 21 as shown by the broken line in FIG. As a result of being tilted about the center, the operating link 16 is swung from its upper limit position to its lower limit position by the biasing force of the spring 19, so that the extending end of one swing link 12a is pushed down via the pin 17. As a result, the bent link 12 is displaced from the lower part of the axis 1 to the upper part, and as mentioned above, the rotation axis 1
0a.

IQb rotates and tongue pieces 9 a, 9 b t 9 c
t 9 d changes from the open state to the closed state.

Although only the fixed frame 4a has been described above, the other fixed frames 4 b t 4 c and 4 d have exactly the same configuration, so their explanations will be omitted for convenience.

Next, as shown in FIGS. 1 to 3, the fixed frame 4a
A transfer conveyor 31 extending in the tangential direction is disposed at a location below the movement paths of t4b, 4c, and 4d, and a recess with an open top surrounded by a diamond-shaped pyramidal wall surface 32a is provided above the starting end of the transfer conveyor 31. An Inari sushi receiver 33 equipped with an entry section 32 is provided.

In the illustrated example, this receptacle 33 is connected to a transfer conveyor 310.
It is divided into two symmetrically by a dividing surface S extending in the width direction, and one of the divided receivers 33a is connected to the transfer conveyor 3.
The other split receiver 33b is fixed to the support frame 34 constructed so as to straddle the one split receiver 33a, while the other split receiver 33b is attached to the tip of the retractable rod 35 that moves in and out on the opposite side to the one split receiver 33a. Supported.

That is, the outer end surface of the other divided receiver 33b is sandwiched between an H-shaped holding frame 37 supported by a horizontal shaft 36 at the tip of the retractable rod 35, and this holding frame 37 is attached to the end surface of the holding frame 37. It is guided into the horizontal guide groove 38 via the provided protrusion 37a.

Further, on the outer side of the receiver 33, as shown in FIG.
1 is erected, and an arm 43 is held at the top of the lifting rod 41 by a bearing 42 so as to be able to freely adjust its protrusion amount.
Above the movement path of t 4 c t 4 d, the above receptor 3
A diamond-shaped block-shaped elevating body 44 is held by its support frame 45 and bearing 46 so as to be opposite to 3 .

The planar shape of the elevating body 44 is similar to that of the upper opening of the sushi rice container 8, which is slightly smaller.

Next, the effect will be explained.

Here, starting from the fixed frame transfer route part above the starting end of the transfer conveyor 31, the fixed frame 4 a
The parts separated by 90 degrees in the moving direction of t 4 b, 4 c, and 4 d are the first device A, and the parts separated by 90 degrees, 180 degrees, and 270 degrees in the same direction from the first device A are the second positions, respectively. B1 third position C and fourth position.

It is assumed that the above-described chevron-shaped cam plate 23 is provided over a portion of the third device C from a portion slightly in front of the third device C to a portion slightly in front of the fourth position.

In such a device, for example, the fixed frame 4a moves from the fourth position to the first device A as the turntable rotates ten times.

In this first apparatus A, the sushi rice container 8 is washed with water, as shown in FIG. 1a.

After washing, the fixed frame 4a is moved to the second device B, and here, as shown in FIG. 7, an appropriate amount of sushi rice R is thrown into the sushi rice container 8.

The loaded sushi rice R is caused by the elasticity of each soft leaf spring member 8at8b, 8et8d of the sushi rice container 8, or by the tongue piece which is in the closed state at this point and is pressed against the outer surface of the sushi rice container 8. Due to the cooperation with the elasticity of 9a, 9b, 9c, and 9a, it is prevented from falling downward (it is carried to the third device C).

When the fixed frame 4a is moved from the second device B to the third device C, the cam follower 24 transfers from the cam base top surface 22a to the cam surface 23a of the chevron-shaped cam plate 23 slightly before the third device C, and therefore the link Due to the action of the mechanism 30, the tongues sa, 9b, 9c, and 9a change from the closed state to the open state as described above, and are separated from the outer surface of the sushi rice container 8.

Since the tongue pieces 9a, 9b, 9c, and 9a still remain open in the third device C, as shown in FIG. Extrapolate fried skin F.

While the fixed frame 4a is moving from the third device C to the fourth position, the cam follower 24 touches the cam surface 2 of the chevron-shaped cam plate 23.
3a to the top surface 22a of the cam stand and link mechanism 30
Since the tongue pieces 9at9b, 9c, and 9d change from the open state to the closed state due to the zero action, the tongue pieces 9at9b, 9c, and 9d change from the open state to the closed state. 9a.

It is desirable to hold the fried skin F by hand until the fried skin F is sandwiched between the sb, 9c, and 9a and the sushi rice container 8.

Next, the fixed frame 4a is moved to the fourth position while maintaining the state in which the fried skin F is held between the sushi rice container 8 and the tongue pieces ga, 9b, 9c, and 9a as shown in FIG. 7d. The machine moves until the end and stops.

In this way, when the fixed frame 4a stops at the fourth position, the elevating body 44, which has been raised until now, is lowered as the elevating rod 41 descends, and the sushi rice is lowered as shown in FIG. 7e. It is inserted into the interior of the container 8 through its upper open opening.

Therefore, the four triangular soft leaf spring materials 8at, 8bt, 8c, 8d of the sushi rice container 8 are pushed out by the elevating body 44 against their elasticity, and the lower part thereof is gradually opened, and at the same time, each of the leaf spring materials 8a , 8b, 8c, and 8d, the tongue pieces 9at9b, 8c, and 8d are also pushed apart against their elasticity, and therefore,
The sushi rice R held in the sushi rice container 8 is placed inside the fried skin F that is extrapolated onto the outer surface of the sushi rice container and held between the tongue pieces 9a, 9b, 9c, and 9a. It is stuffed while pushing out.

In parallel with this, the fried skin F is made of soft leaf spring materials 8a and 8b.
t 8 Cj 8 d and the tongue piece 9 at 9 tz 9 ct 9 a, the Inari sushi ■ consisting of the sushi rice R surrounded by the fried skin F falls and is discharged to the lower part of the sushi rice container 8, and the concavity of the lower suction body 33 The receiver is fixed in the entry part 32.

After this, the other divided receiver 33b is
is retreated from one of the receivers 33a to form a gap between the two, and the Inari sushi (2) is dropped onto the transfer conveyor 31 through this gap and transferred to the next process, for example, the packing process.

The fixed frame 4a, which has thus completed the -cycle, continues to move from the fourth position to the first device A, and the above-mentioned steps are repeated.

During the above cycle, after the worker extrapolates the fried skin F to the sushi rice container 8, this fried skin F is attached to the tongue pieces 9a, 9.
b t 9 c and 9 d that the worker holds the fried skin F in his hands until it is clamped;
As explained above, in this case, the tongue piece 9 a t
The operator did not notice this when 9 b t 9 c t 9 d changed from the open state to the closed state, and as a result, the worker's hand and fingers holding the fried skin F were damaged by the tongue piece 9a,
There is a concern that the person may get caught between the sushi rice container 8 and the sushi rice containers 9b, 9c, and 9a and be injured.

To remove this, after inserting the fried skin F into the sushi rice container 8, immediately pull the safety lever 25 in the direction of movement and use the previously described action to remove the tongue pieces 9at9b, 9c, 9a.
It is best to close it immediately.

The above describes the actions of the fixed frame 4a until it goes through one cycle, but the actions of the other following fixed frames 4b, 4c, and 4a until they go through -cycles are all ( The same is true.

In this embodiment, in the first device A, the sushi rice container 8
Since the inner and outer surfaces of the sushi rice container 8 are washed with water, these surfaces become slippery, and as a result, the sushi rice R can be easily pushed out from the sushi rice container 8 at the fourth position. Rice grains will no longer stick to it.

Further, if Teflon or other synthetic resin material is used as the elevating body 44, the slipperiness between the elevating body 44 and the sushi rice container 8 will be improved, and the sushi rice R can be pushed out smoothly.

As explained above, according to this invention, despite having an extremely simple configuration, Inari sushi can be easily and automatically formed, greatly improving productivity, saving manpower and labor, and In practice, it is possible to save costs.
It's worth being a dog.
