Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food cutting device for cutting food manufactured at a food factory or the like, and more particularly to a food cutting device for cutting food with a cutting blade of an ultrasonic slicer.

[0002]

2. Description of the Related Art Generally, for example, in the case of a food made of bread such as bread and confectionery bread and confectionery such as cake, a cutting device includes a conveyor for placing and transporting food and a conveyor for the conveyor. A slicer provided on the path for cutting the food placed on the conveyor and conveyed. Conventionally, as this slicer, for example, there is a reciprocating slicer having a plurality of saw-toothed bands or straight blades arranged in a line on a conveyor conveying path.However, a filling is packed inside or a decoration topping is placed on the upper surface. When cutting the cut food, there is a drawback that the filling inside the food or the decoration topping on the top moves up and down in the food due to the vertical movement of the cutting blade of the slicer, and the cut surface becomes dirty. Also,
At the time of cutting, since the product moves up and down by the movement of the cutting blade, there is also a drawback that the holding device for preventing the product from floating from above must be provided, and the device becomes complicated. In particular, it is difficult to press a product on which decoration toppings and the like are placed, and in some cases, it has been unavoidable to cut the product by hand using a kitchen knife.

[0003] In order to solve such a drawback, a method using an ultrasonic slicer utilizing ultrasonic waves as a slicer has been generally known and put to practical use. As shown in FIG. 7, the belt 2 is provided with the food F placed on the belt 2 and conveyed thereon, and the belt is provided above the belt 2 of the belt conveyor 1 so as to reciprocate in the width direction of the belt. And an ultrasonic slicer 4 having a cutting blade 3 for cutting the food F placed and conveyed in a transverse direction (e.g., 58-1).
17883 publication). In the cutting by the ultrasonic slicer 4, since the slice surface is very clean and no scum is generated, the food F in which the filling is filled or the decoration topping is placed on the upper surface is easily cut. can do. For example, it is very effective for short cakes and sandwiches. By the way, in the case of the ultrasonic slicer 4, since it is necessary to lower the tip 3a of the cutting blade 3 from the bottom of the food F, conventionally, as shown in FIG. A Century 6 having the same length as the belt 2 having the groove 5 through which the tip 3a of the blade 3 can pass is adhered to the belt 2 so that the bottom surface of the food F can be reliably cut.

[0004]

However, in the conventional cutting apparatus using the ultrasonic slicer 4, the cutting blade is moved in the width direction of the belt to cut the conveyed food transversely. And in order to actually cut it securely,
It is necessary to temporarily stop the belt conveyor at the time of cutting, and it is difficult to perform continuous mass production.
A contour 6 having a groove 5 through which a can pass is adhered to the belt 2, and the contour 6 is as long as the belt 2, and the groove 5 is specially provided on this. Therefore, there is a problem that the production is complicated and the cost is increased. In addition, since the length of the artwork 6 is long, the folding of the belt 2 of the belt conveyor 1 puts an unreasonable burden, and therefore, there is a problem that the durability of the belt is poor. Also,
Conventionally, it is conceivable to divide the belt conveyor into two and provide an interval through which the tip of the cutting blade can pass so that the bottom surface of the food F can be reliably cut. Dividing the belt into two belts has the drawback that it is difficult to eliminate individual meandering due to differences in belt lengths and elongations, and the structure becomes complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and makes it possible to continuously cut a large number of products by an ultrasonic slicer. A food product that can provide easy clearance for the tip of the cutting blade without having to provide a special long contoured groove, which facilitates production and improves durability. It is an object of the present invention to provide a cutting device.

[0006]

In order to achieve the above object, a food cutting apparatus according to the present invention comprises a belt conveyor for placing and transporting food on a belt, and a belt conveyor provided above the belt of the belt conveyor. And an ultrasonic slicer having a cutting blade for cutting the food placed and conveyed on the belt, wherein the cutting blade of the ultrasonic slicer is provided on the surface of the belt of the belt conveyor. A plurality of plate-like blocks on which the food is to be placed are formed along the width direction of the belt by forming a concave strip having a predetermined width through which the leading end can pass. According to this configuration, when preparing a belt for the belt conveyor, a block prepared in advance is attached to the belt.
In this case, simply by attaching the block, a concave streak having a predetermined width through which the tip of the cutting blade of the ultrasonic slicer can pass is formed, so that the tip of the cutting blade is formed on the surface of the belt of the belt conveyor as in the related art. Compared to the case of attaching a contour to the belt with the same length of belt as the belt with the groove through which the part can pass, first the block is easier to manufacture, and the block is small, so it is easier to attach, Belts are easily manufactured. Further, since the belt is formed as a block, an excessive load is not applied to bending of the belt due to the folding of the belt of the belt conveyor, and the durability is improved.

[0007] If necessary, a large number of block rows composed of a plurality of blocks arranged along the width direction of the belt are arranged at intervals along the longitudinal direction of the belt. Thus, since there is a gap between the block rows, the bending of the belt is not imposed by the folding of the belt of the belt conveyor, and the durability is improved. Further, if necessary, the intervals between the block rows arranged along the longitudinal direction of the belt are made equal. Since the blocks are arranged at equal intervals, an unnecessary load is not applied to the bending of the belt, the food is uniformly supported, and the stability is improved.

[0008] If necessary, a holding plate for holding food is erected on each block of a predetermined block row among the block rows arranged along the longitudinal direction of the belt. This ensures that the food is held down,
During cutting by the slicer, the food becomes difficult to move, and the food can be reliably cut into a predetermined shape. Further, if necessary, a plurality of block rows having blocks on which the holding plates are erected are provided at equal intervals. Thus, when the food is supplied by the supply device or the like, the food can be supplied at regular intervals, and the supply is easily performed.

Further, the ultrasonic slicers are arranged in plural rows in the width direction of the belt conveyor. One food can be cut at many places at a time, and the efficiency is improved. In this case, it is effective that the plurality of ultrasonic slicers are arranged with their phases shifted along the longitudinal direction of the belt. Interference between adjacent ultrasonic slicers can be prevented, and the distance between the cutting blades can be reduced accordingly, so that the food can be cut thinner.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A food cutting device according to an embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 6, the food cutting device S according to the embodiment divides a plurality of foods F made of breads such as bread and confectionery bread and confectionery such as cake at equal intervals (in the embodiment). In this example, the apparatus is divided into five equal parts, and includes a base 10, and a pair of belt conveyors 11 provided on the base 10 and arranged in parallel to transport the food F. Each belt conveyor 11
Is a pair of endless belts 12 on which the food F is placed, a pair of support frames 13 extending back and forth from the base 10 and spaced at predetermined intervals, and a belt rotatably mounted between the support frames 13 at both ends. There is provided a pair of rollers 14 around which the belt 12 is wound, and a motor 15 fixed to one end of the support frame 13 and driving one of the rollers 14 to rotate.
Then, the one roller 14 is rotationally driven by the motor 15 to circulate the belt 12 in one direction, thereby conveying the food F.

The base 10 is provided with a plurality of ultrasonic slicers 20 (four in the embodiment) for each belt conveyor 11. This ultrasonic slicer 20
As shown in FIG. 1, a cutting blade 21 is provided above the belt 12 of the belt conveyor 11 and cuts the food F placed on the belt 12 and conveyed in the conveying direction. The cutting blade 21 is formed in a rectangular wedge shape, and is connected to a vibrator 23 via a horn 22. The ultrasonic slicer 20 is mounted on the base 1 via the mounting member 24 such that the cutting blade 21 is inclined and faces the traveling direction of the belt 12.
It is fixed to 0 at an angle of about 45 °. In this case, it is better to sharpen the cutting blade by making the ultrasonic slicer stand as much as possible so that it hits the food vertically, but on the other hand, the cutting blade is wedge-shaped as described above Because the base is in a spread form,
If the ultrasonic slicer is completely twisted, the food may be stuck to the root of the cutting blade and may be damaged, or the root may collide with the presser plate 32, which may hinder the progress of the belt conveyor 11, The ultrasonic slicer is fixed at an appropriate angle in order to improve the sharpness of the cutting blade and prevent food from catching on the base of the cutting blade. In addition, each ultrasonic slicer 20 has the configuration shown in FIG.
As shown in the figure, the belts are arranged in the width direction of the belt conveyor 11 and are arranged out of phase along the longitudinal direction of the belt 12. Pitch P of adjacent cutting blades 21
Are mounted at equal intervals corresponding to the cutting width of the food F. As shown in FIG. 2, the four ultrasonic slicers 20 corresponding to each belt conveyor 11 are arranged mirror-symmetrically.

Further, as shown in detail in FIG. 6, an ultrasonic slicer 2 is provided on the surface of the belt 12 of the belt conveyor 11.
A plurality of (for example, 5 in the embodiment, 5) a concave strip 31 having a predetermined width through which the lower end portion 21a of the zero cutting blade 21 can pass is formed, and the food F arranged along the width direction of the belt 12 is placed.
) Rectangular block 30 is additionally provided. In addition, a large number of block rows 30A including a plurality of blocks 30 arranged along the width direction of the belt 12 are arranged along the longitudinal direction of the belt 12 and at intervals c over the entire circumference. The intervals c between the block rows 30A are set at equal intervals. Belt 12 and block 30
Is made of, for example, urethane resin, and the block 30 is attached to the belt 12 by heat welding.

Further, of the block rows 30A arranged along the longitudinal direction of the belt 12, a predetermined block row 3
At the rear of each block 30 of 0A, a pressing plate 32 having the same width as each block for holding the food F is erected. Presser plate 32
Are provided over the entire circumference of the belt 12 at equal intervals d.
The holding plate 32 is also formed of, for example, urethane resin, similarly to the block 30, and is erected on the block 30 by heat welding. It is desirable that the height of the holding plate 32 be at least half the height of the food F. If the height of the presser plate 32 is less than half the height of the food F, it is pushed when the front upper portion of the food F comes into contact with the cutting blade 21, and the lower portion of the food F rises to cut. This is because it may be impossible or may be crushed by being pressed by the top of the holding plate 32. In FIG. 4, reference numeral 35 denotes a control unit for controlling the drive motor 15 and the ultrasonic slicer 20.

Therefore, the cutting device S according to this embodiment
When the belt 12 of the belt conveyor 11 is manufactured, the block 30 prepared in advance is
At the same time, a press plate 32 having the same width as each block is erected at the rear part A of each block row 30 by heat welding. In this case, just by attaching the block 30, the tip 21 a of the cutting blade 21 of the ultrasonic slicer 20 is formed.
Is formed so that a concave strip 31 having a predetermined width through which the cutting blade can pass can be formed. As compared with the case where the belt 30 is adhered, the block 30 is easy to manufacture first, and since the block 30 is small, it is easy to attach the block 30. Therefore, the belt 12 can be easily manufactured.

Next, when the food F is cut by the cutting device S according to this embodiment, the belt conveyor 11 is used.
Of the belt 12 via the rollers 14
To move. In this state, the block 30 of the belt 12 is
The foods F are sequentially placed on the top. At this time, the food F is placed along the holding plate 32. In this case, since a plurality of block rows 30A having the blocks 30 on which the presser plates 32 are erected are provided at equal intervals d, the food F can be supplied at regular intervals by a feeder or the like, and the supply is easily performed. . This allows
The food F is transported, and in this transport process, the ultrasonic slicer 2
0, the cutting blade 2 of the ultrasonic slicer 20
It is cut by 1. In this case, the cutting blade 21 of the ultrasonic slicer 20 passes between the concave strip 31 and the pressing plate 32 between the blocks 30, so that the food F is cut without interfering with the cutting blade 21 and the cutting blade 21. Is lower than the bottom surface of the food F, so that the bottom surface of the food F is reliably cut. Further, in this case, since the intervals c between the block rows 30A are equal, the support of the food F becomes uniform and the stability is improved, so that the cutting is reliably performed. Further, since the food F is pressed by the pressing plate 32, the food F becomes difficult to move when the cutting blade 21 cuts the food F, and is reliably cut into a predetermined shape.

In the cutting by the ultrasonic slicer 20, since the ultrasonic slicers 20 are arranged in a plurality of rows in the width direction of the belt conveyor 11, one food F is cut at many places at one time. Since the plurality of ultrasonic slicers 20 are arranged out of phase along the longitudinal direction of the belt 12, interference between adjacent ultrasonic slicers 20 is prevented, and the pitch P of the cutting blade 21 can be reduced. Thus, the food F can be cut thinner. Furthermore, since a large number of the block rows 30A are arranged at intervals c along the longitudinal direction of the belt 12, the belt 12 is easily bent even if the belt 12 of the belt conveyor 11 is folded at the roller 14 portion. Therefore, since an unreasonable load is not applied to the belt 12,
Durability is improved.

In the above embodiment, the food F is intended for breads such as bread and confectionery bread and confectionery such as cakes. However, the present invention is not necessarily limited to this, and the present invention is applicable to various other foods. Of course, it is good.

Can be cut with a very clean sliced surface and without leaving scum, and the food can be easily cut even if the food is filled with filling or a decoration topping is placed on the upper surface. Further, according to the food cutting device of the present invention, the food is placed on the surface of the belt of the belt conveyor, while forming a concave streak of a predetermined width through which the tip of the cutting blade of the ultrasonic slicer can pass. Since a plurality of plate-like blocks arranged along the width direction of the belt are provided, a recess having a predetermined width can be formed only by attaching the blocks. Compared to the case where a Turkish that has a groove that can pass through is adhered, the manufacture of the block is easier, and the block is small, so that it is easy to attach the block. Therefore, the belt can be easily manufactured. Further, since the belt is formed as a block, an excessive load is not applied to the bending of the belt due to the folding of the belt of the belt conveyor, so that the durability can be improved.

Further, when a large number of block rows composed of a plurality of blocks arranged along the width direction of the belt are arranged at intervals along the longitudinal direction of the belt, the belt is folded back on the belt conveyor. Even if there is, the belt is easily bent, so that an unreasonable load is not applied to the belt, so that the durability can be improved. Further, when the intervals between the block rows are equal, the support of the food becomes uniform and the stability is improved, so that the cutting can be surely performed.
