Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is used to produce foods that completely enclose the inner wrapping material, such as steamed buns and ohagi. The present invention relates to a wrapping cutting method and apparatus for continuously dividing supplied fabric so that the inner wrapping material is not exposed.

(Prior Art) As a conventional wrapping cutting device, there is one such as the one disclosed in Japanese Patent No. 587809, in which the rod-shaped dough discharged from a continuous rod-shaped body with a double structure is cut by a multi-layer shutter made by stacking many thin plates. The opening of the shutter is opened and closed to cut the rod-shaped fabric that passes through the opening, but when cutting, the inner wrapping material is covered with the outer skin material due to the fabric sticking to the shutter. A sufficient enveloping effect could not be obtained.

The present inventor has already invented a method for solving the above-mentioned drawbacks (Japanese Patent Publication No. 63-29979).
The method involves applying pressure from three or more circumferential directions to the outer periphery of a continuous rod-shaped covering fabric,
This is a wrapping cutting method in which the pressing surface gradually bites into the fabric so that as pressing progresses, the pressing surface gradually becomes smaller toward the middle part of the member in the thickness direction.

(Problems to be Solved by the Invention) The present invention aims to further improve production capacity, improve measurement accuracy during cutting, and solve the problem of material adhesion in relation to the prior invention. be.

(Means and effects for solving the problem) The method of the present invention is the same as the method of the earlier invention, that is, pressing the outer circumference of a continuous rod-shaped wrapping fabric with a surface from three or more circumferential directions. , and as the pressing progresses, the pressing surface moves toward the middle part in the thickness direction of the member, so that the contact area with the fabric gradually decreases. , is an enveloping cutting method in which the repetitive cutting motion is performed while reciprocating in the axial direction, thereby improving production efficiency by at least two times or more.

And, as a device directly used for carrying out the above-mentioned enveloping cutting method, two adjacent sides are used as sliding surfaces,
A frame at the center of a frame in which three or more square pieces, each of which is formed into a square pyramid shape with the junction of the two sliding surfaces at the apex at the middle in the thickness direction, are combined with their sliding surfaces in contact with each other. is a passage for the fabric, and the frame body is provided to move up and down along the passage of the fabric. This wrapping cutting device is characterized in that a conveyor is provided to move up and down.

Since the rectangular pieces of the present invention are formed as described above, when the rectangular pieces slide and the surrounding area gradually becomes smaller, the cloth contacting portion of each rectangular piece will
It bites into the center of the rod-shaped wrapping material while gradually decreasing its contact area with the material in the thickness direction, and at the same time, a movement of descending a certain distance is performed in parallel. By gradually decreasing the contact area of the fabric as it moves toward the center of the fabric, the contact area guides the outer skin of the fabric to the center without producing the wedge input effect that occurs with ordinary knives. The outer skin completely covers the inner packaging material and separates.

Since the frame body moves up and down in synchronization with the opening and closing of the enclosure along the discharge direction of the rod-shaped covering fabric, even if the fabric is continuously dispensed, when the enclosure is closed, it will stagnate on the top surface of the enclosure. This will increase productivity. It also prevents the dough from sticking to the frame, and also improves the measuring accuracy when dividing the dough.

Another overall effect is that when the enclosure gradually becomes smaller, the fabric-contacting surface of the square piece slides against the fabric in its circumferential direction and bites into the center of the fabric. The force directed to the cutting site is further increased to achieve a completely enveloped cut.

(Example) To explain the cutting means of the present invention based on an example, as shown in FIG. 3, and the joint between the sliding surfaces 2 and 3 is formed into a square pyramid shape with an apex 4 at the middle in the thickness direction. Therefore, at the joint between the sliding surfaces 2 and 3, two triangular slopes exist between the sliding surfaces 2 and 3.

As shown in FIG. 2, in the device of the present invention, three or more 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 frame 5. And, by the sliding surfaces 2 of three or more square pieces 1 housed in the frame 5,
A continuous rod-shaped wrapping material made of a material 7 and an inner wrapping material 8 is supplied to the central portion thereof, passing 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 vertices 4 come to one place as shown in FIG. In the assembled state, the enclosure 6 is in a closed state, thereby performing the wrapping cutting of the rod-shaped wrapping material. Further, when the above-mentioned enveloping cutting operation is completed, the square piece is moved in the opposite direction to the direction of the arrow S, so that the enclosure 6 at the center gradually becomes larger, and the bar-shaped piece is moved toward the inside of the enclosure. Covering fabric is supplied.

In the present invention, the fabric 7 is supplied in a continuous bar by repeating the opening and closing movement of the enclosure.
At this time, the fabric 7
In the case where the inner wrapping material 8 is continuous with the inner wrapping material 8 at the center, it is possible to cut the inner wrapping material 8 without exposing it.

The reason why this special effect occurs is that, 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 against the fabric 7 digs into the center of the fabric 7, and as the enclosure becomes narrower, the upper and lower contact surfaces are changed from a to a by the slope from the vertical direction. Therefore, in the present invention, as described above, as the contact surface bites into the fabric, the fabric 7 located at the contact surface becomes smaller than the inner wrapping material 8.
is pushed in the direction of arrows m and m, and the rod-shaped material can be wrapped and cut with the inner packaging material wrapped in the fabric 7.

This effect is 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 sticks and cannot 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 moves upward and downward, that is, in the direction of arrows m and m.
It causes a flow in the direction. 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.

By lowering the rectangular piece 1 at the same speed or an approximate speed _v1 as the discharge speed v of the dough 7, it is possible to improve the production volume, prevent adhesion problems, and improve cutting accuracy.

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 this example, 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. That is, 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 of gradually reducing the initial wide contact area a, and causing the sliding surface 2 facing the enclosure to bite into the fabric. This is done by sequentially narrowing down three or more planes, and the effect is stabilized by descending.

Furthermore, to explain the effect of the slopes formed on the square piece, these two slopes are the area where the sliding surface 2 contacts the fabric and bites into it (the length in the thickness direction of the square piece). ) is provided to perform the action of gradually decreasing the

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, can lead to cutting.

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 or lower slope is missing and only one slope is formed, the product cut by the square piece will be covered only on the side corresponding to the slope. However, the other horizontal side is not covered and is simply sheared.

In other words, as in the case where the square piece does not have an inclined surface, or as in the case of conventional wedge cutting, the inner wrapping material is not trapped in the fabric, but is in an open state, and the wrapped bulb is cut. It becomes something that cannot be done.

When using the rectangular piece of the present invention having the above-mentioned shape, the sliding surface 2 of the rectangular piece bites into the fabric, and when the fabric is moved toward the center, the sliding surface 2 of the rectangular piece continues above and below the contact surface 2. The provided slope facilitates the movement of the fabric and enhances the enveloping effect.

Furthermore, as shown in FIG. 7, when the enclosure 6 is closed, the slopes gather at the center to form a depression, and the surface contact with the fabric causes the lower slope to reach the bottom of the fabric. The upper slope facilitates the formation of a covering of the head of the fabric.

Therefore, in the square piece of the present invention, it is necessary that the upper slope and the lower slope are joined at the middle of the sliding surface 2 in the thickness direction. Then, as mentioned above, the junction point is at the top 4
As shown in , it is necessary to form the four surfaces in such a way that they are joined at one top.

The present invention can be constructed by combining six square pieces as shown in Figure 2, but it is also possible to combine four square pieces as shown in Figure 9. In that case, the enclosure is formed into a rectangular shape. By sliding the rectangular pieces in the direction of arrow S, the enclosure is closed with the tops 4 in contact with each other, and the material is cut.

Furthermore, as shown in FIG. 10, it can be constructed by a combination of three square pieces. Then, the enclosure formed by the square piece at its center is formed into a triangular shape, and by sliding the square piece in the direction of arrow S, the action of enveloping and cutting the rod-shaped material is performed. It is something that can be done.

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 surfaces 2 and 3 of adjacent rectangular pieces 1 are in sliding contact with each other, and an outer sliding surface 9 and an outer frame 10 are sliding. In this shutter device, as shown in FIG.
A pin 12 is provided at one location, a slider 13 has a hole into which the pin is inserted, a crank rod 14 is pivotally attached to one end of the slider 13, and the other end of the crank rod 14 is supported by a crankshaft 15.

The crankshaft 15 has a slide gear 16 and a gear 1
It is rotated by the drive of a motor 19 via 7 and 18. The slider 1 is rotated by the rotation of the crankshaft 15.
3 slides and the pin 12 operates, the rectangular piece 1 slides and the enclosure 6 performs an opening/closing motion.

The outer frame 10 is provided to be movable up and down by a support shaft 20, and one end of a crank rod 23 fitted to the crankshaft 22 of the motor 21 is pivotally attached to the outer frame 10 by a pin 24. , motor 21
The outer frame moves up and down by the rotational drive of.

25 is a discharge device that continuously discharges the rod-shaped dough, and 27 is a conveyor that conveys the cut products. The conveyor 27 is provided with a rear end roller 29 movable up and down about a roller 28.

Next, the frame body 5 is opened and closed, the outer frame 10 and the conveyor 27
To explain the operation timing of the vertical movement, one cycle of the opening and closing movement of the enclosure is included during the downward movement of the outer frame 10. That is, at the same time as the outer frame 10 starts to descend, or before or after the start, the enclosure 6 begins to close, then closes, then begins to open, and after the enclosure has completely returned to its original position, the outer frame begins to rise. It begins and returns to top dead center, and box 6 remains open during this ascent. Then, the same action will be repeated again.

Assuming that cutting is performed without the frame moving up and down, the continuously discharged bar-shaped dough will stagnate on the top surface of the box when the box is closed, causing the dough to swell as shown in Figure 16. Even if the enclosure is opened, it may become impossible for the fabric to pass through the enclosure, and it may also become sticky.

The conveyor 27 is designed to move up and down in synchronization with the up and down movement of the outer frame 10. Further, during the downward motion, the conveyor 27 is stopped, and during other motions, the conveyor 27 is operated intermittently.

The effect produced by the movement of the outer frame 10 and the conveyor 27 in synchronization with the opening and closing of the frame body 5 is noticeable when cutting continuously discharged bar-shaped dough. Also, regarding the conveyor moving up and down, while the fabric is being cut by the enclosure,
Since it is possible to prevent the product from falling downward due to its own weight, the top surface of the cut product remains in contact with the enclosure until the end, making it possible to effectively cover the top surface of the cut product. In addition, the top part of the product does not become trailed when the product falls, which is the case with particularly soft products.

(Effects of the Invention) As detailed above, the present invention provides an extremely simple method and device for supplying a continuously discharged rod-shaped dough having an inner wrapping material without exposing the inner wrapping material. Can cut accurately.
