Abstract

PROBLEM TO BE SOLVED: To reduce the number of components for a device, miniaturize the device, reduce the cost, and favorably cut foods, especially finely chop by arranging a rotating mask and a rotating cutter in the vertical fixed positions and arranging a belt conveyer conveying the foods in such a manner as crossing therebetween. SOLUTION: When a squid 30, for example, is mounted on a belt conveyer, the squid 30 is cut by a circular thin blade 10 of the rotating cutter B while moved between a rotating mask A and a rotating cutter B. The squid 30 is pushed upward by the tensile force of a wire belt 20 to be separated from the rotating cutter B and delivered by a belt conveyer C. In this case, the rotating mask A alternately and sequentially inserts a lot of discs 4 and a lot of spacers 5 inserted between the respective discs 4 and forms circumferential grooves 7 at prescribed pitches. On the other hand, the rotating cutter B alternately and sequentially inserts a lot of circular thin blades corresponding to the respective circumferential grooves 7 and a lot of spacers 11 inserted between the respective circular thin blades 10 into the rotary shaft 12.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting foodstuffs, and more particularly to a cutting apparatus for cutting or cutting foodstuffs such as fish such as squid and flounder, processed foods such as ham and konjac, and buckwheat.

[0002]

2. Description of the Related Art In the case of a conventional cutting device, for example, a squid shredding device, the present applicant uses a movable rotary cutter (rotary cutter) to open or close a mask plate manually or mechanically. A moving cutting device has been proposed (JP-A-9-37708). Although this conventional device can provide the desired effect, one cutting cycle takes too much time because the rotary cutter reciprocates and the mask plate opens and closes, shortening the cutting work cycle and improving productivity. Was desired. Therefore, in order to improve workability and productivity, a cutting apparatus as shown in FIG. 5 in which a stationary rotary cutter and a rotary mask are combined with a belt conveyor is tried.

In FIG. 5, reference numeral 101 denotes a rotary cutter,
02 is a rotating mask, 103 is a carry-in belt conveyor, and 104 is a carry-out belt conveyor. In this cutting device,
By placing the open squid 100 on the belt conveyor 103, the squid is transported between the rotary cutter 101 and the rotary mask 102, and passes between the two members 101, 102 to be transported by the rotary cutter 101 in the transport direction. Cut along
It is carried out by the carry-out conveyor 104.

[0004] However, the following problems were found in the cutting apparatus according to the above-mentioned trial example. First, as shown, belt conveyors 103 and 104 and rotating mask 102
In between, intermediate members 105 and 106 for smoothly delivering or delivering the squid are required. Further, on the rotating cutter side, a scraper 107 for separating the squid from the rotating cutter 101 is required to prevent the squid from rolling up. Accordingly, the intermediate member 105, 106, the scraper 107, and the like are required in combination with the two belt conveyors for carrying in and carrying out, and the number of members is increased and the production cost is increased. Second, since there is an intermediate member 105 which is a stationary member between the rotary cutter 101 and the carry-in conveyor 103, it is necessary to increase the food pull-in force between the rotary cutter 101 and the rotary mask 102. 101, 102
The need to increase the diameter increases the size and costs. Third, the circular blade of the rotary cutter 101 generally uses a stainless steel material having excellent corrosion resistance and strength, but the circular blade made of stainless steel is likely to be warped due to contact friction or cutting friction with the rotary mask and causes rotation blur. Therefore, it is difficult to make the blade thinner. Generally, the circular blade of the rotary cutter 101 uses a disk having a thickness of about 2 to 3 mm.
Therefore, not only is the processing cost of the cutting edge increased, but also when the food material is finely cut, the food material is stressed, and the quality and texture are impaired.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention reduces the number of members of an apparatus, reduces the size of the apparatus, reduces the manufacturing cost, and ensures that the operations of loading, cutting, and unloading food materials are performed functionally. Accordingly, an object of the present invention is to increase the productivity of the cutting operation of food materials, and to provide a cutting device suitable particularly for finely cutting food materials.

[0006]

According to the present invention, a rotary mask having a plurality of circumferential grooves arranged at a predetermined pitch and a rotary cutter having a circular thin blade corresponding to the circumferential grooves are rotated at fixed upper and lower positions. A wire belt conveyor is disposed so as to cross between the rotary mask and the rotary cutter, and the rotary cutter inserts the cutting edge of each circular thin blade into each circumferential groove of the rotary mask. The belt conveyor is a food cutting apparatus in which each of the wire belts on the upper side thereof is arranged under tension between the circular thin blades of the rotary cutter on the lower surface of the rotary mask, respectively, to form a conveying surface. . That is, in the cutting device of the present invention, the pair of rotary masks and the rotary cutter are disposed at fixed upper and lower positions, and the belt conveyor configured by the wire belt is disposed so as to cross between the rotary mask and the rotary cutter. It is characterized by the following.

According to the present invention, the food material placed on the upper side of the wire belt conveyor is carried between the rotating rotary mask and the rotary cutter by the transport operation of the conveyor. That is, the food material is carried not only by the drawing force by the rotating mask and the rotating cutter but also by a large drawing force increased by the conveying force of the belt conveyor. Then, at the time of the cutting operation in which the food material is transferred between the rotary mask and the rotary cutter, the food material is cut by the circular thin blade of the rotary cutter while being pressed and supported between the wire belt and the rotary mask. Further, when the food material passes between the rotary mask and the rotary cutter, the food material is conveyed upward by the tension of the wire belt, that is, is carried out by the advance of the belt conveyor while a force in a direction away from the rotary cutter acts.

On the other hand, the rotary cutter has a cutting operation,
In other words, during the rotation operation, both side surfaces of the disk portion are supported by the wire belt stretched in a tensioned state, thereby preventing the rotation blur. Therefore, the circular thin blade of the rotary cutter can be thinned, but is preferably a soft material such as urethane rubber in order to prevent warpage of the rotary cutter, that is, to reduce friction. That is, the present invention is characterized in that the wire belt is made of a soft material and is disposed close to the disk portion of each circular thin blade, and the disk portion of the circular thin blade is a stainless steel thin blade of 0.5 mm or less. (Claim 2).

[0016]

According to the present invention described above, the food material placed on the upper side of the wire belt conveyor has not only the drawing force of the rotating mask and the rotating cutter but also the large drawing force increased by the conveying force of the belt conveyor. In addition to this, it is possible to reliably carry out the operation of loading the foodstuff, and it is possible to prevent an unnecessary increase in the diameter of the rotating mask and the rotating cutter, an increase in the size of the apparatus, and an accompanying increase in cost. In addition, since the food material is pressed and supported between the wire belt and the rotating mask during the cutting operation, the cutting operation can be performed reliably. Further, when the food material comes out from between the rotary mask and the rotary cutter, a force in a direction away from the rotary cutter acts on the food material due to the tension of the wire belt, so that the separating operation and the unloading operation of the food material can be reliably performed. Can be done. Therefore, the operations of loading, cutting, and unloading the food can be functionally ensured, and the productivity of the cutting operation of the food can be increased.

Further, the rotating cutter is supported by the wire belt during the rotating operation to prevent the rotation blur, so that the cause of the warpage of the cutter is prevented and the circular thin blade can be thinned. Therefore, according to the second aspect, the cost for forming and processing the circular thin blade of the rotary cutter is reduced, and the manufacturing cost of the apparatus is reduced in combination with the maintenance of the reduced size of the rotary mask and the rotary cutter and the reduction in the number of belt conveyors. Can be reduced. On the other hand, by making the rotary cutter thinner, even when the food is finely chopped, the texture after cutting can be favorably maintained, which is particularly suitable for finely chopping food such as squid.
