DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food cutting device suitable for cutting foods in units of a predetermined length.

[0002]

2. Description of the Related Art Conventionally, as a cutting apparatus for cutting foods of a predetermined shape in units of a predetermined length by cutting foods continuous in a longitudinal direction such as a bar or a plate, for example, they are arranged in parallel at predetermined intervals. Provided with a plurality of rotating blades and a food supply table, a `` slitter '' that cuts the food on the supply table by rotating the rotating blade manually or electrically, and a single straight blade or a plurality of straight blades at predetermined intervals With the knife frame arranged in parallel,
For foods such as "Guillotine-type cutter" that pushes and cuts food on the cutting table at once, and "Slicer" that has a rotating round blade and a food supply table, and reciprocates the supply table with respect to the rotating round blade to cut food. A cutting device is used.

[0003] In the above-mentioned cutting apparatus for food, breads such as ham, sausage, bread, etc., having the inside of foods in a cohesive state and having appropriate adhesiveness and flexibility, are used.
It is suitable for cutting kneaded products such as kamaboko, or bar sushi such as nori roll sushi, and provides a good cut surface and can improve cutting efficiency.

[0004] However, there are foods in which solid granular food materials are solidified while maintaining their shape, for example, "Oshishi". In this "Oshioshi", a void portion composed of a large number of air bubbles is formed inside the food. In the case of foods that have been glued and solidified with a solid agent such as starch syrup, when cutting using the above-mentioned cutting device, the edge of the cut may be chipped due to the impact of the blade or the adhesion between the food materials may be broken There is a problem that the shape of the food is lost, and the cross-sectional shape of the material of the cut surface is crushed, thereby impairing the appearance of the food and reducing the commercial value.

[0005] In the case of thin slices, which are cut to a thickness of several millimeters, the conventional cutting apparatus causes the shape of the food to be remarkably deformed, and the shape of the food cannot be maintained. Was almost impossible.

Further, in the conventional cutting apparatus, when the cutting length is changed or finely adjusted, it takes time and money to reduce workability due to replacement of blades and parts and to prepare replacement parts. In addition, there is a problem in that since many operations are performed manually, the burden on the operator is large, and the cost is high economically.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is intended for cutting a solid-length food material into a fixed length of solid food while maintaining its shape. Can also prevent chipping of the cut end due to the impact of the blade, deformation of the food material due to adhesive destruction, and crushing of the cross-sectional shape of the material on the cut surface. An object of the present invention is to provide a food cutting device that can be maintained and can produce a product with high commercial value.

Further, the cutting length and the operating speed are easily adjusted, the handling is excellent, the maintenance of the apparatus is simple, and the labor can be saved. It is an object to provide a cutting device.

The running and the supply of food by the transport device are performed in synchronization.

According to this food cutting device, the reciprocating travel of the rotary blade and the drive are transmitted to the transfer device and the transfer device via the transmission and the reduction gear by the use of one electric motor as the driving force, and the rotary blade is operated. Since the reciprocation of the food and the supply of food are performed in synchronization, the device has a simple structure and is easy to handle and maintain.Furthermore, since the components of the device are operated mechanically synchronously, the operation can be performed without disrupting the timing. Work reliability is improved.

[0011] In the above-mentioned food cutting device, a second aspect of the present invention is provided.
As described above, the rotary blade reciprocates in the width direction of the food corresponding to the supply of the food to the cutting position, cuts the tip of the food to a certain length, the transport device, the rotary blade, Stopping while cutting food while reciprocating, and performing intermittent motion to supply the next food cutting portion to the cutting position by operating forward while the reciprocating movement of the rotary blade is completed and retreating from food. It is.

Thus, the food can be reliably and accurately cut by the rotary blade in accordance with the supply timing of the food due to the intermittent movement of the transport device. Further, since the stationary food is cut by the rotating rotary blade, the cut surface can be prevented from being chipped or deformed, and can be used for thin cutting, and an ideal cut surface and an ideal product appearance can be obtained.

According to a third aspect of the present invention, the reciprocating travel distance of the rotary blade for cutting food and the transport distance of the transport device for supplying the food to the cutting position are two crank mechanisms connected from the one electric motor. Can be adjusted by the distance between the crankshaft center and the connecting rod axis.

Thus, the cutting length and width of the food can be easily set in a short time in a short time, and the workability is improved.
