Description

[Detailed explanation of the idea] This invention relates to an automatic oshizushi making machine.

Generally speaking, oshizushi, also known as hakozushi, is made by packing sushi rice into a wooden box, arranging fish and shellfish meat on top, and applying pressure by hand.

However, this work is very hard work for the workers when manufactured repeatedly and continuously, and it has become a problem in the industry in recent years from the viewpoint of the working environment and the user's retention rate, and the demand for automation has increased. be.

In recent years, in order to meet these demands, sushi rice,
An automatic feeding mechanism for fish raw materials is provided near a pair of sprockets and a caterpillar endless track, and a molding box is connected and fixed to this caterpillar, and a press molding device is provided in front of the box in the direction of movement, so that the box moves along the outer periphery of the sprocket. An automatic sushi making machine has been proposed which has a configuration in which the sushi is discharged and conveyed to a conveying device at a position where the sushi is opened downward.

However, although this proposed machine can certainly be mass-produced, it cannot be used in regular stores for various reasons, such as the production volume is too large for practical purposes, and the machine is large and takes up a lot of space. Yes.

Also, it was used as a rice ball manufacturing device.
The publication was also published in 1974 as a rice ball manufacturing device.
12077, however, these previously reported devices have the disadvantage that the molded product does not reliably separate from the mold when feeding the molded product, causing the molded product to lose its shape. There were also drawbacks such as rice adhering to the surface, which interfered with driving and required time and effort to clean.

In light of the above circumstances, the inventor proposed a simple device, rather incorporating manual mechanisms for mechanisms that do not require automation, and extruding molded products such as oshizushi, which had been a problem with the above proposal and conventional rice ball manufacturing devices. At the time, peelability from the equipment and shape retention of the molded product was a problem, and improvements were made to the delivery mechanism and equipment cleaning for the molded oshizushi, and automatic oshizushi manufacturing with a production capacity of around 2,000 pieces per hour. He continued his intensive research on the machine, and finally completed his idea after many failures.

It is composed of chains 40, 41, 42 and transmission shafts 43, 44.

As detailed above, the automatic push-pull making machine according to this invention can be positioned manually or by an automatic mechanism.
The peeling plate 45 and pieces of fish meat are supplied to the hole ₂₀ at the position _P0 , and when the automatic sushi rice feeding mechanism 32 is not used, the sushi rice is supplied manually.

The disk 1 is sequentially moved in the direction A by 1/8 circumference (in this embodiment) by the action of the pin gear 10 that transmits the force from the drive motor 7 and the Geneva gear 4.

When this hole ₂₀ reaches position _P1 , if a sushi rice feeding mechanism 32 is provided, a certain amount of sushi rice is first supplied to the hole ₂₀ at position _P1 , or sushi rice is supplied manually in advance. When the disk 1 is stopped, the pressing plate 16 presses the material in the hole 20 by the action of the cylindrical cam 12, the connecting rod 13, and the push-down shaft ₁₂ that transmit the force from the drive motor 7. , and press it.

The push-down shaft 12 immediately pushes upward, and at the same time the disk 1, which had stopped due to intermittent movement, moves the hole ₂₀ to the position.
Perform an intermittent circular motion, sending to P ₂ and stopping.

At position P ₂ , the molded pusher in the hole ₂₀ pushes down the push shaft 1 at the same time as the disk 1 stops.
In the second movement, the peeling plate 20 and the pusher are dropped onto the belt 18 by the sending plate 17.

Note that the receiving disk 1a is fixed to the main body frame 5, and the hole 2
The peeling plate 20 and the material on the disk ₁ are supported on the lower side of the disk 1, and the portions directly below the positions P ₂ and P ₃ are cut out to facilitate the operation of the feeding mechanism.

The belt 18 receives power from the drive source 7 intermittently to the roller shaft 21 via the cylindrical cam 12 and the crank 24, and as a result moves in the direction B, and the belt 18 moves out of the machine together with the peeling plate 20. transported.

Next, the hole ₂₀ , which has been moved to position _P3 , cleans the sushi rice crumbs adhering to the inner wall of the hole by the action of water contained in the cleaning member 29 in advance and the frictional force of the material 29, such as a sponge.

In this way, the hole ₂₀ whose inner wall has been cleared returns to the position _P0 again.

The automatic oshizushi making machine according to this invention has a disk 1
moves intermittently, and during the stop time of the disk 1 in this intermittent movement, the pressing device, the feeding mechanism, the cleaning device (and the peeling plate 20 feeding device and sushi rice feeding mechanism provided near the position P ₀ as necessary), It operates and continuously produces oshizushi. The sushi rice supply device 32 provided here as needed supplies the required amount of sushi rice to the sushi rice hopper 36 in advance, and then power is intermittently transmitted to the gears 38, 39, 45 via the transmission shaft 44, and the belt 33 is moved. The sushi rice is sent to the rollers 35 and ₃₅₂ one by one by intermittent endless motion.

The rollers 35 ₁ and 35 ₂ send the sushi rice to the position P ₁ using the circular rotational force transmitted from the gear 39 via the reversing gear 47 and the gears 46 and 48 coaxial with the rollers rotating in the same direction.

At this time, the sushi rice is crushed by the action of the needle-like projections 49 formed on the outer peripheral surface of the roller ₃₅₁ .
₂ and the belt 33, they are sequentially sent to _P1 .

The amount of sushi rice supplied to the hole ₂₀ at this time is adjusted by the number of needle-like protrusions 49 provided on the roller ₃₅₁ and the feeding speed of the belt 33.

As described in detail above, the automatic push-pull making machine according to the invention has a simple pressing device, a feeding mechanism, a
Since the cleaning mechanism is provided, the shape of the entire machine is simply restricted to the size of a disk, so it can be made very compact.Also, the raw material is supplied to the hole 2 through the peeling plate 20, and along with this peeling plate 20, Since we decided to transport the product to the outside of the machine using a delivery mechanism, we improved the disadvantages of the conventional caterpillar type machine, which had poor peelability and shape retention of the product from the machine, by using a release plate. Moreover, it has a simple cleaning mechanism, and instead of conventional machines requiring large-scale equipment such as steam cleaning, it has a simple mechanism that cleans the rice starch before it becomes beta solidified, making the entire machine more compact and producing 2,000 yen per hour. This is an epoch-making automatic oshizushi making machine that has the ability to produce small batches.
