Problems to be Solved by the Invention These devices are practical and can cut the wrapping with certainty. However, when mass-produced or operated for a long time, the cutting members may be burned or become inoperable. And the production stops. Also,
These devices are of a reciprocating opening and closing type in which the cutting member is swung about a fulcrum provided on the circumference, so that at the time of cutting, dough fragments and hand dust are collected at the center, so that unnecessary unnecessary foreign substances are collected. May cause sticking, or the inner packaging material may be exposed when the device is opened after cutting.

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problem, and its structure is as follows.
In order to form an enclosure at the center A of a circumference a drawn by a radius R by gathering radially, a plurality of rotation shafts B of the same shape rotatably fitted to rotation shafts B provided at equal intervals on the circumference a. A division molding apparatus comprising a polyhedron, wherein the polyhedron is located at a distance a ′ from the center A when the shortest distance between the adjacent rotation axes B and B is a ′, and has a radius R from the rotation axis B. A point x ₁ at a distance is obtained, and the surrounding is formed by a side surface defined by an arc y ₁ having a radius of a distance a ′ about x ₁ , and the polyhedron is formed by continuation on the same plane. In order to cut and form the bar-shaped dough passing through the box by a rotary motion, the polyhedron is made to cooperate so as to narrow down the box by the side surface of the polyhedron. And, when the central box is closed, each polyhedron can be completely closed without interference, and after closing, the polyhedron is opened in the rotating direction of the polyhedron, so that hand flour and dough fragments remain. There is nothing. Further, since there is no sliding between the sides of the polyhedron, problems such as burning can be solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment. FIG. 1 is an explanatory view for explaining the shape of a polyhedron 1 which is a feature of the present invention. In FIG. 1, a rotation axis B, which is a rotation axis of the polyhedron 1 arranged in four equal parts, is provided on a circumference a drawn with a radius R around the point A. Adjacent rotation axis B
Assuming that the shortest distance between them is a ′, two points x ₁ and x ₂ that are at the shortest distance a ′ from the center A and are at a distance from the rotation axis B to R are obtained, and these points x ₁ and x ₂ are determined. At the center, the polyhedron 1 having arcs y ₁ and y ₂ having a radius of the shortest distance a ′ as a first side surface 11 and a second side surface 12 is provided. The upper and lower surfaces of the polyhedron 1 are flat and parallel. These polyhedrons 1 are placed on the same plane,
When the rotation axis B is provided vertically and the rotation axis B is co-rotated in one direction so that the respective tips 2 of the four polyhedrons 1 gather at the center A, an enclosure as shown in FIGS. 3 opens and closes. This is because the two end portions 2 do not interfere with each other when the polyhedron 1 rotates, and the first end portion 2 and the second side surface 12 (hereinafter, referred to as the first and second side surfaces 12) of the polyhedron 1 adjacent to each other when the two end portions 2 rotate. (Referred to collectively as "side surface 11 or 12").

Next, a specific example of the apparatus will be described.
As shown in the figure, a cutting device for the polyhedron 1 which is a feature of the present invention is provided below the dough supply device 4 for discharging the double bar-shaped dough. A rotating shaft 6 corresponding to the rotating shaft B shown in FIG. 1 is provided in the housing 5, and the polyhedron 1 is mounted on the same plane. One end of the rotating shaft 6 is provided with a timing pulley 8 in which a timing belt 7 is engaged. A polyhedron is synchronously driven and transmitted by a motor 9 mounted on the housing 5. The housing 5 is moved up and down in synchronization with the rotation of the polyhedron 1 by a vertically moving device (not shown). As shown in FIGS. 2 to 4, the timing of the up and down movement gradually decreases as the box 3 is closed, and then rises and returns while the box 3 does not interfere with the cloth when the box 3 is open. ing.

Next, the function and effect of the present invention will be described. A bar-shaped material 10 composed of an outer shell material and an inner wrapping material is supplied to the enclosure, and the enclosure is gradually closed. The cloth material 10 is pressed by the side surface 11 or 12 and the outer skin material is moved toward the center.
At this time, the side face 11 or 12 causes the fabric 10 to be a polyhedron 1
The surface area of the constricted part formed by being pressed up and down
Cutting can be performed without thinning the outer cover material or exposing the inner cover material. At this time, the amount of movement of the outer skin toward the center by the side surface 11 or 12 can be adjusted by changing the thickness of the side surface 11 or 12 that presses the fabric. Therefore, in addition to the embodiment having a constant thickness T, the shape of the polyhedron is changed in thickness toward the tip 2 as shown in FIG. 6 in order to adjust the amount of movement of the skin material in the center direction. This makes it possible to cut the wrapping according to the properties of the dough such as bread dough and confectionery dough. Generally, in these wrapping cuts, the thickness T of the polyhedron depends on the properties of the fabric,
It is effective that the diameter is equal to or less than the diameter of the bar-shaped material, and the thickness of the tip is also adjusted. When the fabric is cut with such a configuration, the envelope can be cut without thinning or breaking the outer skin material. In addition, since the tip 2 of the polyhedron 1 traces the side surface 11 or 12 of the adjacent polyhedron 1, if the fabric is adhered to the side surface 11 or 12, it is peeled off by this.
Even an adhesive and soft material can be cut without any obstacle. In the embodiment of the present invention, it is described that the cloth is cut twice by one rotation of the polyhedron with four polyhedrons, but the invention is not particularly limited to four polyhedrons. For example, the embodiment shown in FIG. 7 is another example composed of four polyhedrons, in which the other end of the two side faces of the polyhedron is omitted. In this case, the polyhedron is rotated once per rotation. This is to cut the dough. FIG.
Since the second side surface 12 of the polyhedron has substantially nothing to do with the encapsulation cutting operation, the side surface 12 may be cut away in the direction of the rotation axis B and omitted. FIG. 8 shows an example in which three polyhedrons are arranged. In this case, the side surface 11 or 12 is used.
In addition to, providing the side surface 13 that can be in an arc y ₃ of arc y _1, y ₂ can intersect the circumference d drawn from the center A 3
It is a polyhedron consisting of two sides. In this case, it is possible to cut the envelope three times in one rotation. As another example, for example, even if the circumference a is divided into five equal parts and five or more pieces are prepared, the envelope cutting can be performed. By changing the number of polyhedrons to three or four or changing the number of side faces of the polyhedron in this way, the number of wrapping cuts per rotation is changed, and the size of a product to be cut is changed. It becomes possible.

[0008]

According to the present invention, polyhedrons of the same shape provided at equal intervals on the circumference continuously rotate while tracing the side faces of adjacent polyhedrons without interfering with each other. Therefore, unlike the conventional movement by sliding of the sliding surface, continuous operation is possible without causing seizure. In addition, since the tips are gathered at the center by the continuous rotation of these polyhedrons and then opened, hand flour and dough fragments do not accumulate and can be wrapped and cut without any problem. Encapsulation can be cut without obstruction of adhesion. Furthermore, by changing the number of polyhedrons and the number of side faces of the polyhedron, the production amount and the like can be freely changed.
