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, so there is a demand for it to be provided to the market more efficiently than by hand.

This invention was made in view of these circumstances, and is an automatic molding device that can sequentially perform the various processes necessary for the production of Inari sushi on a circular path around a turntable. This is something that we are trying to provide as a new product.

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

1 to 47, 1 is a turntable, 2 is a drive motor thereof, and on the outer periphery of the turntable 1 are four mounting brackets 3a, 3b, and 3c.

3d are installed every 90 degrees, and these mounting brackets 3a, 3
A fixed frame 4 with a U-shape in plan view is installed at the rising portions of b, 3c, and 3d.
a, 4b, 4c, and 4d are fixed to the turntable 1 so as to protrude in the radial direction.

The mounting brackets 3 a , 3 b , 3 c , 3 d are attached to the turntable 1 by tightening bolts 6 a , 6 b , 6 c , and 6 a that pass through long holes 5 a , 5 b , 5 c , and 5 d formed in these. , is fixed to this turntable 1, and bolts 6a and 5b
By loosening t 6c and 6d, each fixed frame 4a
, 4b, 4c, and 4d can be easily adjusted so that they all move on the same circular path.

Next, there are support metal fittings in the shape of a dogleg and a dogleg at the top of the fixed frame 4a. A and 7b are arranged to face each other so as to be left and right symmetrical, and this pair of supporting 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 is made by arranging four triangular soft leaf spring materials aa, 8b, 8c, and 8d in the shape of a rhombic pyramid with an open top, into which sushi rice is placed. To some extent, their elasticity maintains the rhomboid-pyramidal natural state.

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

On the outer surface side of 8d, there is a set of two tongue pieces 9a.

9 b , 9 c , 9 d are arranged, and these tongue pieces 9
a.

Each set of 9b, 9c, and 9a is fixed separately to a pair of rotating shafts 10a and 10b arranged symmetrically opposite to each other on the fixed frame 4a.

The rotating shafts 10a, 10b are horizontally supported by bearings 11a, lla, llb, llb provided on the fixed frame 4a, as shown in FIGS. 5 and 6. , whose proximal ends are each bent link 1
A pair of swinging links 12a and 12b forming the structure 2 are fixed to respective swinging centers Pa and Pb of the swinging links 12a and 12b.

In this case, the folded links 12 each swing link 12 a
, 12b, elongated holes 13a, 13 formed at the swinging ends of the
The pair of swinging links 12a and 12b are connected by a pin 14 through a pin 14, and due to its telescoping function, the upper parts are symmetrical to each other via an axis 1 connecting the two swinging centers. A bending displacement is possible between the position and the lower position.

Moreover, one swinging link 12a of the folded link 12 is
A long hole 15 is formed at the end of the extension to the opposite side of the swing center Pa, and a shaft is inserted into the long hole 15 near the outside of the swing center pb of the other swing link 12b. The free end of the supported actuating link 16 is engaged via a pin 17.

Note that 18 connects the base end of the operating link 16 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 ten parts thereof, A cam follower 24 is attached to the lower end of the cam follower support rod 20 in correspondence with the cam surface 23a of the chevron-shaped cam plate 23.
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 upper end support shaft 28 of the cam follower support frame 20.

In the above configuration, the cam mechanism 29 is achieved 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 rotation axes IQa, 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 indicated by the arrow X in FIG. moves in the direction indicated by arrow Y in FIG. The cam 7 follower 24 provided at the lower end of the cam follower support rod 20 is connected 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 slidably vertically installed 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 26 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 kept swinging to the lower limit, thereby preventing the middle bending. The link 12 is held above the axis 1, so that the tongue pieces 9a, 9b, 9C29d fixed to the rotation shafts 10a, 10b 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, as shown by the imaginary line in FIG. The tongue pieces 9a+9b, 9 are held at the bottom of 1 and are therefore fixed to the pivot shafts 10a, 10b.
c and 9d are opened as the rotation shafts 10a and 10b rotate, and are separated from the outer surface of the sushi rice container 8.

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 of the swing links 12a is pushed down via the pin 17, Along with this, the bent link 12 is displaced from the lower part of the axis line ■ to the upper part, and eventually, as described above, the rotation axis 10a
, 10b rotate, and the tongue pieces 9a, 9b, 9c, and 9d change from the open state to the closed state.

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

Next, as shown in FIGS. 1 to 3, the fixed frame 4
A transfer conveyor 31 extending in the tangential direction is disposed at one location below the movement path of a t 4 b, 4 c, and 4 d, and the upper part of the starting end of this transfer conveyor 31 is surrounded by a rhombus-pyramidal wall surface 32 a. An Inari sushi receiver 33 having a recessed portion 32 with an open top 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 this elevating condo 410 by a bearing 42 so that the amount of protrusion can be freely adjusted.
, 4d, a diamond-shaped block-shaped elevating body 44 is held by its support frame 45 and bearing 46 so as to face the receiving body 33.

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
, 4 b + 4 c, and 4 d are separated by 90 degrees in the moving direction as the first device A, and parts separated by 90 degrees, 180 degrees, and 270 degrees in the same direction from the first device A are the second devices, respectively. B, third device 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. 7a.

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 pressed against the outer surface of the sushi rice container 8 due to the elasticity of each soft leaf spring member 8a, 8b, 8ct8d of the sushi rice container 8, or is in a closed state at this point. Tongue pieces 9 a t 9 b, 9 e, 9 d
It is carried to the third device C without falling downward due to the cooperative action of the elasticity of.

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 By the action of the mechanism 300, the tongue pieces 9 a , 9 b , 9 c t 9 are formed as described above.
d changes from the closed state to the open state and separates from the outer surface of the sushi rice container 8.

Since the tongue pieces 9at9b, 9c, and 9d still remain open in the third device C, they are fried from the lower part of the sushi rice container 8 onto its outer surface in the third device C, as shown in FIG. 7C. Extrapolate 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
0 action causes tongue pieces 9a, 9b.

9c and 9d change from the open state to the closed state, so the third
In order to prevent the fried skin F inserted into the sushi rice container 8 in the device C from falling, the tongue pieces 9a and 9b are used.

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

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 9a, 9b, 9c, and 9d as shown in FIG. 1d. 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 as shown in FIG. It is inserted into the interior of the container 8 through its upper open opening.

Therefore, the four triangular soft leaf springs 8a, 8b, 8c, and aci 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 plate Spring materials 8a, 8b.

Tongue pieces 9a, 9b, 9c were in pressure contact with 8c, 8d.

Along with this, the sushi rice R held in the sushi rice container 8 is pushed out and expanded against its elasticity, and the sushi rice R held in the sushi rice container 8 is extrapolated to the outer surface of the sushi rice container 8 to form the tongue piece 9a.

9 b t 9 c t 9 d This fried skin F is stuffed into the inside of the fried skin F which is held between the two.

In parallel with this, the fried skin F is made of soft leaf spring materials 8a and 8b.
, 8c, 8d and tongue piece 9a 29b.

9 c and 9 d, Inari sushi I made up of sushi rice R surrounded by fried skin F is placed in sushi rice container 8
The receiver is dropped and discharged downward, and the receiver is stopped in the recessed part 32 of the receiver 33 at the lower part.

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, 9b.
, 9c and 9d, the operator holds the fried skin F in his hands (as explained above).
The worker did not notice this when 9c and 9d 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 pieces 9a, 9b, 9c, 9d
There is a concern that people may get injured if they get caught between the container and Sushi Rice Container 8.

In order 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 its movement and remove the tongue piece 9a by the above-described action.

It is preferable to immediately close 9b, 9c, and 9d.

The above describes the action of the fixed frame 4a until it goes through one cycle, but the action of the other following fixed frames 4b, 4c, and 4d until they go through -cycle is also explained. are exactly the same.

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.

Further, according to the present invention, by operating the manually operated safety lever, the continuous state between the cam mechanism that constitutes the opening/closing mechanism of the tongue piece and the tongue piece is released, so that the operator can enjoy the sushi rice. If this safety lever is operated immediately after inserting the fried skin into the container, unexpected accidents caused by the operator not noticing the change of the tongue piece from the open state to the closed state due to the above-mentioned opening/closing mechanism can be avoided. can be prevented.
