Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cutting device for cutting a sushi roll of a predetermined length into a plurality of pieces.

(Prior Art) As shown in FIG. 4, this type of conventional cutting device is equipped with a plurality of cutting blades 55 that reciprocate up and down in a transition path of a table 11 that reciprocates horizontally, or a rotary cutting blade that can be moved up and down. The sushi roll 9 is placed on the table and moved forward, and the cutting blade is inserted into the groove 12 formed on the table to cut the sushi roll into pieces.

(Problem to be solved) If you observe a sushi chef cutting sushi rolls, you will notice that the angle of the knife relative to the sushi changes significantly from the beginning of cutting to the end. This is the key to cutting sushi beautifully. However, with the above-mentioned conventional cutting device, the angle of contact of the cutting blade against the sushi roll on the table until the end of cutting is constant, resulting in a state close to a forced cut, which deforms the cut end and reduces the product value. is decreasing.

Furthermore, with conventional cutting devices, once the table moves forward and the sushi roll passes the cutting blade, the sushi roll must be taken out from the table immediately, and the table must retreat to its original position before placing the next sushi roll on the table. Operation is intermittent and work efficiency is poor.

(Means for solving the problem) In view of the above, the present invention is capable of cutting sushi rolls while greatly changing the cutting angle of the cutting blade against the sushi roll from the beginning to the end of cutting, as in cutting with a sushi knife. This project reveals a device that can continuously cut sushi rolls.

The present invention includes a rotating drum 2 which is connected to a rotary drive device 73 and has a plurality of receiving portions 21 on the outer periphery formed at equal intervals in the circumferential direction, and a cutting blade 5 which cuts the sushi rolls on the drum. It is composed of a supply device 3 that supplies sushi rolls to the drum 2, and a discharge device 4 that discharges the sushi rolls on the drum 2.

On the outer periphery of the drum 2, circumferential grooves 22 are formed at equal intervals in the axial direction and perpendicular to the axis, into which the cutting blades 5 enter.
Both ends of the cutting blade are clamped to upper and lower rods 55 and 56 of the frame, and the upper end of the frame is guided by guide grooves 54 of guide plates 53, 53 arranged on both sides of the frame, The lower end of the frame is pivotally connected to the free end of a lever 81 which has one end pivoted, and as the lever 81 rotates, the cutting blade 5 moves up and down in a large arc, and the cutting blade 5 moves up and down with each rotation of the drum 2. The cutting blade 5 reciprocates in accordance with the number of parts 21, and the sushi rolls in the receiving part 21 are cut by one reciprocation of the cutting blade 5.

(Operations and Effects) The sushi rolls 9 are fed one by one by the feeding device 3 to the receiving portion 21 of the continuously rotating drum 2. The cutting blade 5 is reciprocating while the drum 2 is rotating.
Cutting starts when the sushi roll 9 hits the sushi roll, and when the sushi roll passes the cutting blade 5 as the drum 2 rotates, the cutting ends.

The cutting blade 5 has an upper end guided by a guide groove 54 extending vertically on a guide plate 53, and a lower end guided by a rotating lever 8.
The sushi rolls are connected to the free end of 1 and move up and down, so they do not just move up and down vertically, but move up and down while drawing a large arc, and while being cut, the sushi rolls are radially centered around the rotation center of the drum The cutting angle of the cutting blade 5 on the rolled sushi changes greatly from the beginning of cutting until the end of cutting.
For this reason, the sushi rolls are not pressed into shape, and the cut sushi rolls are not deformed and the cut edges are beautiful. Furthermore, since the cutting blade does not cut in one reciprocating motion, but only in forward motion, the pressing force against the sushi roll due to the friction between the cutting blade and the sushi roll acts in one direction.
The sushi roll does not swing on the receiving part, and in this respect, the sushi roll can be cut stably and beautifully.

Moreover, the receiving part 2 of the rotating drum 2 is supplied by the supply device 3.
By sequentially providing the sushi rolls 1 to 1, a large amount of sushi rolls 9 can be continuously cut into pieces with high efficiency.

(Example) In FIG. 1, a rotary drum 2 is rotatably provided in the center of the upper surface of a base 1 with its axis horizontally, with a supply conveyor 3 on the left side and a supply conveyor 3 on the right side with the drum 2 in between. A discharge conveyor 4 is provided.

The drum 2 has a diameter of approximately 170 mm and a length of approximately 200 mm, and has three receiving portions 21 on its circumferential surface, on which sushi rolls are placed, formed at equal intervals in the circumferential direction.

As shown in FIG. 2, in the embodiment, the peripheral surface of the drum 2 is hollowed out in the axial direction to a depth where the rolled sushi is inserted into the receiving part 21.
is formed.

Further, on the circumferential surface of the drum 2, circumferential grooves 22 having a width of about 2 mm are provided at equal intervals in the axial direction perpendicular to the axis of the receiving portion 21.
It is opened a little deeper than that.

The drum 2 is connected to seven rotary drive devices via a chain 71, and is rotated clockwise in FIG.

In the embodiment, the supply device 3 is a V on which the sushi rolls 9 are placed.
This is a bucket conveyor in which letter-shaped bucket carts 32 are arranged at regular intervals on a circulating chain 31, and the conveyor is configured such that the bucket carts 32 are arranged at equal intervals on a circulating chain 31, and the bucket carts 32 are arranged at regular intervals on a circulating chain 31.
orbits at the speed of 3 paces.

The discharge device 4 is a belt conveyor in the embodiment.

A plurality of band-shaped cutting blades 5 are disposed between the discharge device 4 and the drum 2, and are fitted into each circumferential groove 22 of the drum 2 and reciprocate up and down.

Both ends of each cutting blade 5 are removably clamped to upper and lower rods 55 and 56 of a support 51 formed in a rectangular frame.

The support body 51 is supported by a pair of guide plates 53 erected on the base 1 with the sushi roll transition path in between, and a reciprocating drive device 8 that reciprocates the support body 51.

A guide groove 54 is formed in the vertical direction on the inner surface of the guide plate 53.
is formed, and rollers 52 provided at both ends of the upper rod 55 of the support body 51 are fitted into the groove 54 so as to be able to roll.

The reciprocating drive device 8 includes a crank driven by the rotary drive device 7, with the lower end of the support body 51 pivoted to the free end of a lever 81 which is pivoted at one end by the base 1 and is swingable in a vertical plane. 82 is pivotally connected to the lever 81.

Therefore, when the rotary drive device 7 rotates, the rotation of the drum 2 and the vertical movement of the cutting blade 5 are synchronized, and the drum 2
The cutting blade 5 reciprocates up and down three times during one rotation.
Furthermore, the timing is such that when the cutting blade 5 descends, the sushi rolls 9 on the drum 2 come into contact with the cutting blade 5.

The stroke of the cutting blade 5 is 3 times the diameter of the sushi roll 9.
However, the effective stroke for cutting sushi rolls is approximately three times that of sushi rolls.

In the example, the stroke of the cutting blade 5 is 180 mm, the diameter of the sushi roll 9 is approximately 45 mm, and the stroke of the cutting blade 5 is approximately 35 mm.
When the cutting blade 5 descends by 135 mm, the sushi roll 9 hits the cutting blade 5 and cutting begins, and when the cutting blade further descends by 135 mm, the cutting of one sushi roll ends.

A cleaning device 6 for the cutting blade 5 is provided at two locations above and below the drum 2.

As shown in FIG. 2, the cleaning device 6 has a base plate 6 each having a groove 61 into which the cutting blade 5 enters.
A sponge 64 and a silicone resin plate 64 are fixed under narrow pressure between the groove 61 and the pressing plate 63.
The end surfaces of the sponge 60 and the silicone resin plate 64 are placed against the cutting blade 5 sandwiched between the two.

A water tank 65 is provided above the guide plate 53, and a tube 66 connects the water tank and each cleaning device 6. The water tank 65 contains a solution of vinegar diluted with water, which is led to the cleaning device 6 through a tube and constantly leaks the sponge 64.

The amount of liquid supplied can be adjusted by a flow rate adjustment valve 67 provided in the tube 66.

Thus, the sushi rolls 9 are placed one after another on the bucket 31 of the supply device 3.

When the bucket 31 is reversed at the downstream end of the supply device 3, the sushi rolls 9 in the bucket are released, hit the rotating drum 2, and are fitted into the receiving part 21 of the drum 2.

While the drum 2 is rotating, the sushi roll hits the cutting blade 5 moving downward to start cutting, and when the sushi roll passes the cutting blade 5 as the drum rotates, the cutting is completed.

The cutting blade 5 has an upper end guided by a guide groove 54 extending vertically on a guide plate 53, and a lower end guided by a rotating lever 8.
The sushi drum 2 is connected to the free end of the cutting blade and moves up and down, so it does not just move up and down vertically, but moves up and down while drawing an arc.
Therefore, as shown in FIG. 3, the angle at which the cutting blade 5 cuts into the sushi roll changes greatly, resulting in a beautiful cut of the sushi roll.

The cut sushi rolls are rolled onto the discharge device 4 by the rotation of the drum, and are discharged by the device 4.

When cutting sushi rolls, a paste-like substance adheres to the cutting blade 5, but the cutting blade is wiped with the sponge 60 and silicone resin plate 64 of the cleaning device 6 every time the cutting blade reciprocates up and down. The cutting blade 5 is always kept in a leaking state with the diluted vinegar solution, and its sharpness does not deteriorate.

In addition, diluted vinegar has a sterilizing effect and can prevent bacteria from growing on the cutting blade.

As mentioned above, the receiving part 2 of the rotating drum 2
By sequentially feeding the sushi rolls to the sushi machine 1 using the feeding device 3, the sushi rolls can be continuously cut into pieces, greatly improving work efficiency.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims for utility model registration.
