Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applied to the production of foods such as steamed buns and ohagi, in which the inner wrapping material is completely enclosed by the outer skin material. This invention relates to continuously dividing a dough having an inner wrapping material and supplied as a continuous rod-shaped body so that the inner wrapping material is not exposed.

(Prior art) There is a conventional cutting device such as that disclosed in Patent No. 587809, in which the rod-shaped dough discharged from a continuous rod-shaped body with a double structure is cut by a multilayer shutter made of many thin plates stacked on top of each other. The rod-shaped fabric that passes through the opening is cut by opening and closing the opening, but when cutting, the inner wrapping material may not be sufficiently covered by the outer covering material, or the fabric may be shattered. A sufficient enveloping effect could not be obtained due to reasons such as adhesion to the material.

(Problems to be Solved by the Present Invention) The present invention solves the above-mentioned drawbacks, and makes it possible to cut the fabric discharged by a double-structured continuous rod without exposing the inner wrapping material. The object of the present invention is to provide a method and apparatus that are simple and capable of continuous production.

(Means and effects for solving the problem) The present invention provides the following features: from the circumferential direction of a member in three or more directions;
Pressure is applied by a surface from the outer periphery of a continuous rod-shaped wrapping fabric, and as the pressure progresses, the contact area of the pressing surface with the fabric gradually becomes smaller toward the middle part of the thickness direction of the member. This is a covering cutting method in which the surface is gradually bitten into the cutting surface.

In the present invention, the central enclosure formed by combining three or more rectangular pieces whose sliding surfaces are on two adjacent sides with their sliding surfaces in contact with each other is used as a passage for the fabric, and the sliding surface of the rectangular pieces is The surfaces are slid against each other to gradually reduce the size of the area, and the material inserted into the area is cut.

Further, the boundary between the two sliding surfaces of the square piece is cut diagonally from the top and bottom to form a slope, and the square piece is configured to become gradually thinner toward the top formed by the slope. Therefore, when the square pieces slide and the surrounding area gradually becomes smaller, the fabric contacting part of each square piece gradually decreases the fabric contact area in the thickness direction and reaches the center of the rod-shaped fabric body. It digs in, and when the enclosure is closed at the center position, it produces a covering and cutting effect.

By gradually decreasing the contact area of the fabric and moving toward the center of the fabric, the contact area guides the outer skin of the fabric to the center without creating a wedge effect like a typical knife. The outer skin completely covers the inner packaging material and separates it.

Furthermore, another overall effect is that when the enclosure gradually becomes smaller, the fabric contacting surface of the square piece slides against the fabric in the circumferential direction and bites into the center of the fabric. The force that guides the material to the cutting site is further increased to achieve a complete envelope-like cut.

(Example) To explain the cutting means of the present invention based on an example, as shown in FIG. The images 2 and 3 are formed as sliding surfaces, and the top 4 is formed with respect to the line where the two sliding surfaces 2 and 3 touch.
Slopes 4a and 4b cut diagonally toward the surface are formed.

Further, the angle formed by the sliding surfaces 2 and 3 is a value determined by the number of square pieces, and when three square pieces are combined, 360/3=
120°, and when combining four square pieces,
Set to 90°.

As shown in FIG. 2, in the device of the present invention, a plurality of square pieces 1 are combined, and each square piece is brought into contact with its adjacent sliding surfaces 2 and 3.
It is housed inside the framework 5.

And the square pieces 1, 1 accommodated in the framework 5
An enclosure 6 is formed in the center by the sliding surfaces 2 of..., and a continuous rod-shaped material constituted by the fabric 7 and the inner wrapper 8 is fed through the enclosure 6.

In FIG. 3, the arrow S indicates the direction of movement of the square piece 1. When the square piece moves in this direction, the box 6 becomes smaller, and eventually the contact points 4 converge at one point as shown in FIG. In this state, the enclosure 6 is in a closed state, thereby allowing the rod-shaped material to be wrapped and cut.

Also, when the above-mentioned wrapping and cutting operation is completed,
The rectangular piece is then moved in the opposite direction to the direction of the arrow S, whereby the enclosure 6 in the central part gradually becomes larger and the rod-shaped dough 7 is fed into the enclosure.

In the present invention, the dough 7 supplied in a continuous rod is cut by repeating the opening/closing movement of the enclosure, and at this time, the inner wrapping material is cut at the center of the dough 7 in a continuous state. For those that have the inner packaging material 8, the effect of cutting is produced without exposing the inner packaging material 8.

The reason why this special effect occurs is as explained in FIG.
As shown in the figure, a depression is formed in the fabric 7, but at the same time, the area of the contact surface 2 becomes smaller in inverse proportion to the amount of the depression, and eventually the fabric 7 is cut as shown in FIG.

During this time, the contact surface 2 of the sliding surface 2 with respect to the fabric 7
4 digs into the center of the fabric 7, and as the encircle narrows, the slope 4
The upper and lower contact surfaces become smaller in the order of a→a′→a″ due to a and 4b. Therefore, in the device of the present invention, as the contact surfaces dig into the fabric, as described above, Fabric 7 located in the contact surface area
pushes the inner wrapping material 8 in the direction of arrows m and m, and with the inner wrapping material wrapped in the fabric 7, the rod-shaped material can be wrapped and cut.

This effect means that when pressure is applied to the dough from a surface perpendicular to it, the portion of the dough that is in contact with this surface 2 will stick and will not be able to flow up and down.
The inner packaging material 8 moves toward the center while maintaining its original thickness, and as a result, the inner packaging material 8 flows up and down, that is, in the directions of the arrows m and m.

If the direction of the pressure of the surface in contact with the fabric is not perpendicular to the fabric, a wedge effect will occur and the fabric cannot be wrapped and cut.

FIG. 8 shows the phenomenon of wedge cutting, and is intended to explain the difference in effect between the present invention and the prior art. In the case of this reference, unlike the present invention, the surface that bites into the material is at an acute angle from the beginning, so the flow of the excluded internal material is directed outward with respect to the cut surface, as shown by m'. The inner packaging material 8 is exposed from the cut surface.

In other words, when cutting with a blade made at a simple acute angle, it is not possible to cut in a wrapped state due to this wedge effect.

The effect of the present invention, which is different from such a conventional cutting method using an acute angle, is due to the method in which the initially wide contact area a is gradually reduced, and the sliding surface 2 facing the surrounding area digs into the fabric. By sequentially narrowing this sliding surface by three or more surfaces and by reducing the vertical contact area with the material, the effect of covering the inner material with the outer skin is stabilized. It is something that

Furthermore, to explain the effects of the slopes 4a and 4b, these two slopes gradually reduce the area (length in the thickness direction of the square piece) where the sliding surface 2 contacts the fabric and bites into it. It is provided to perform the function of

The sliding surface 2 causes a biting action on the rod-shaped fabric when the square piece 1 moves in the direction of arrow S, so by gradually reducing the width of the biting surface, the rod-shaped fabric can be It can lead to amputation.

At this time, if the rod-shaped dough body has a rod-shaped covering structure in advance, it can be cut into balls in the wrapped state. In this case, if either the upper slope 4a or the lower slope 4b is missing and only one slope is formed, the product cut by the square piece will only be cut on the side corresponding to the slope. is in a covered state, but the other horizontal surface side is not covered and is simply sheared.

In other words, the inner wrapping material is not trapped in the fabric, as in the case where the square piece has no slope, or as in the case of conventional wedge cutting, but is released, and the enveloped bulb is cut. becomes impossible.

That is, when using the rectangular piece of the present invention having the above-described shape, the contact surface 2 of the rectangular piece bites into the dough, and as the dough moves toward the center,
Slope 4 provided above and below the contact surface 2
a and 4b act to promote movement of the fabric and enhance the enveloping effect.

Furthermore, as shown in FIG. 7, when the enclosure 6 is closed, the slopes 4a..., 4b... converge at the center to form a depression, and due to their surface contact with the fabric, The slope 4a helps cover the bottom of the fabric, and the slope 4b covers the top of the fabric.

Therefore, in the square piece of the present invention, it is necessary that the upper slope 4a and the lower slope 4b are joined at the middle of the sliding surface 2 in the thickness direction. As described above, the joining point needs to be formed in such a manner that four surfaces are joined at one top, as shown by the top 4.

The wrapping cutting device of the present invention can be constructed by combining six rectangular pieces as shown in FIG.
As shown in FIG. 9, it is possible to construct it by combining four rectangular pieces 1a, and in that case, as shown in FIG. 9a, the enclosure 6a is formed in a rectangular shape. Then, mark the square piece 1a with an arrow S
By sliding in the direction, the enclosure is closed with the tops 4 in contact with each other, as shown in Figure b, and the cutting action of the material is performed.

Furthermore, as shown in FIG. 10, the device of the present invention can be constructed by a combination of three square pieces 1b. Then, the box formed at the center by the square piece 1b is formed into a triangular shape, so that the state shown in a is changed to the state shown in b in the figure.
By sliding the square piece, it is possible to perform the action of enveloping and cutting the rod-shaped material.

In FIG. 11, an outer sliding surface 9 is provided on one side of a square piece 1, a plurality of square pieces are combined with each other via the sliding surfaces, and the combination of square pieces is housed in an outer frame 10. A shutter device 11 is shown in which sliding pieces 2 and 3 of adjacent square pieces 1 are in contact and sliding, and an outer sliding surface 9 and an outer frame 10 are sliding.

In this shutter device, as shown in FIG. 13, a crank pin 12 is provided at one location of a square piece 1, a rod 13 acting as a fulcrum is fitted onto this, and the other end is fitted onto a pin provided on a slider 14. By fitting and moving the slider with the crank 15 and sliding one square piece 1,
A movement is generated in which the other square pieces are sequentially slid in an interlocking manner.

As shown in FIG. 12, the enclosure formed by the rectangular pieces is gradually narrowed to perform the action of enveloping and cutting the rod-shaped material. Therefore, in the apparatus of the present invention, by repeating the above-described operations, the enclosure 6 can be opened and closed to continuously cover and cut the rod-shaped material.

(Effects of the Invention) As detailed above, according to the present invention, when a rod-shaped fabric having an inner wrapper is supplied, it can be cut without exposing the inner wrapper using an extremely simple method and device.
