Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sushi cutting device capable of automatically cutting sushi such as pressed sushi which requires cutting.

[0002]

2. Description of the Related Art Sushi, especially pressed sushi such as buttera, is formed by pressing ingredients (mackerel, conger eel, trout, sea bream, etc.) on sushi rice and pressing the lump to form a lump. . The formed lump of sushi is taken out of the box, cut by a sushi chef with a kitchen knife into a predetermined size, and provided as a product. However, it takes a special skill to cut lump sushi into individual pressed sushi products, and when an unskilled person cuts the sushi rice, the ingredients on the sushi rice become misaligned and lose their shape. It often became pressed sushi with no commercial value. Further, even a skilled person needs considerable concentration and rhythm to cut the pressed sushi so that it does not lose its shape, so there is a problem such as fatigue, and the time for continuous cutting work is limited. limited. Therefore, there is a limit to cutting a large amount of pressed sushi by a limited number of craftsmen due to this time limitation.
In recent years, sushi has been displayed in stores such as supermarkets, and there is an increasing need to supply a large amount of sushi within a short time.

[0003] Therefore, the inventors of the present invention cut the belt-shaped pressed sushi continuously into a predetermined size within a limited time without losing its shape, and a large amount of pressed sushi within the limited time. We previously invented a sushi automatic cutting device that can provide
Currently underway. As shown in FIGS. 5 and 6, this automatic sushi cutting device has a circular blade c that is rotationally driven in a gap between a first conveyor a and a second conveyor b that are adjacent to each other with a predetermined gap.
Is reciprocated to cut the sushi s at the cutting position on the first conveyor a detected by the sensor d. The circular blade c is rotationally driven by the rotary drive source e and is vibrated in the thickness direction by the vibrating device f, while the sushi s
Is to disconnect.

[0004]

However, in the above automatic sushi cutting device, it is necessary to move the round blade c together with the rotary drive source e and the vibration device f in the cutting direction, and to retreat after cutting the sushi s. Therefore, there is a problem that the means of movement for moving forward and backward becomes large-scaled and the equipment cost becomes high. An object of the present invention is to solve the above conventional problems. That is, the belt-shaped pressed sushi can be continuously cut into a predetermined size without losing its shape, and a large amount of pressed sushi can be provided to the market within a limited time. An object of the present invention is to provide an automatic sushi cutting device which is simplified and does not need to move the cutting means at all, and has a simple structure and can be provided at low cost.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a first conveyor for intermittently driving sushi before cutting, and a first conveyor with a predetermined interval in the same direction. The second adjacent to which sushi after cutting is conveyed
Connected to a conveyor, a cutting blade that is arranged on the side of both conveyors, in which two blades in the shape of a sword blade are alternately inserted into a gap between both conveyors, and a rotary drive source that rotates the cutting blades. The sushi on the first conveyor is provided with a sensor that detects the sushi when it is conveyed to the cutting position and that activates the rotary drive source. Furthermore,
Below the cutting blade, a water-filled container into which the blade portion penetrates by the rotation of the cutting blade is arranged. Further, a roller for cleaning sushi rice or the like adhering to the second conveyor by freely rotating in contact with the second conveyor is arranged at the sushi transfer completion position of the second conveyor.

[0006]

When the block-shaped sushi is placed on the first conveyor, the sushi is sent forward by the intermittent drive of the first conveyor. When the sushi is conveyed to the position of the gap between the first conveyor and the second conveyor, the sensor detects that the sushi has reached a predetermined position, and this signal is transmitted to the rotary drive source. The rotary drive source receives the signal and rotationally drives the cutting blade. By rotating the cutting blade, sushi is cut by the blade-shaped blade of the cutting blade. Furthermore, the blade portion of the cutting blade wipes off the sushi rice cake adhering to the inside of the water-filled container and imparts moisture to the blade portion. After cutting once, the rotation of the cutting blade is stopped once, but when the sushi is conveyed further forward, the cutting blade is rotated again to cut the sushi.

When the rotation speed of the cutting blade is made to correspond to the cutting dimension of sushi, after cutting the sushi with one blade portion of the cutting blade, the other blade portion by the rotation of the cutting blade is
It is also possible to further cut the sushi that has been conveyed forward by a certain size. The cut sushi is placed on the second conveyor, further conveyed, and taken out. In addition, the second conveyor cleans the adhered sushi rice and the like by the roller arranged at the sushi conveyance completion position.
