2. Description of the Related Art A method of cutting a plastic food material that is mass-produced and continuously extruded is to dispose several shutter bodies on a polygonal circumference and extrude the food material between the shutter bodies. However, a method of squeezing food materials by linearly sliding each shutter body toward the center of the polygon at an appropriate position (Jitsuko Sho 63-29433, Japanese Patent Fair)
1-42652) is known.

The inventor of the present invention has also developed a device excellent in motion transmission efficiency to the shutter body, which is capable of cutting the plastic food material only by simple rotation or rotation movement of the shutter body. Wishhei 4-42183, Special Fairness 2-345
No. 93).

However, all of these are intended only for reliable cutting of continuously extruded rod-shaped food products,
In particular, for cored bar-shaped foods made of two or more kinds of materials, the emphasis is placed on the covering cutting, in which the core material is cut cleanly without being exposed on the surface.

Therefore, although the cutting efficiency of various foods has been dramatically improved by these cutting devices, the shape of the foods to be produced is limited to the dumpling type or the bales type. The actual situation was that, in the case of molding into a predetermined shape, it also depended on manpower. As a device for mechanically forming and processing rod-shaped foods, it is possible to use a die, but it is clear that it is extremely difficult to perform a molding treatment on a food material that has a complicated mechanism and has adhesive properties such as rice cake. Is.

A cored bar-shaped food F (core material f ₁ and outer skin material f ₂ ) made of various kinds of food materials is continuously extruded. The extruded rod-shaped food F is introduced into the molding / cutting region 2 described below, and the molding / cutting process is performed.

As shown in FIG. 2, the molding cutting region 2 is formed by being surrounded by four isomorphic shutter bodies 1.1.1.1.1 that are symmetrically arranged in a shutter frame 3c having a square shape. Each shutter body has a deformed quadrangular shape having two right angles, and the straight side facing the molding cutting area 2 of each shutter body is a cutter side 1a. The cutter side 1a is adjacent to the cutter side 1a. The matching side is the sliding side 1b, and the side adjacent to the cutter side 1a on the other side is the sliding side 1c. Then, the cutter side 1a of each shutter body abuts the sliding side 1b of the adjacent shutter body, and the slide side 1c of each shutter body abuts the inner wall of the shutter frame 3c. A molding cutting area 2 is formed on the inner side by the cutter side 1a.

In this embodiment, the opening / closing mechanism for the molding / cutting area 2 is fixed to one shutter body at one end.
The transmission member 3a has a female threaded portion at the other end; a shaft 3b having a male threaded portion corresponding to the female threaded portion at its tip; and a control motor 4 for imparting rotational movement to the shaft 3b. Shaft 3b is shutter frame 3c
Since it is installed parallel to the inner wall and its axial movement is restricted by the locking member 3d, the rotational movement of the shaft 3b is converted into the sliding movement of the shutter body 1 along the inner wall of the shutter frame 3c. . In this way, the one shutter body to which the sliding motion is applied pushes the sliding side 1b of the adjacent shutter body with the cutter side 1a while contacting the inner wall of the shutter frame 3c. This pressing relationship extends to all shutter bodies, so that each of the four shutter bodies
The linear sliding movement is performed to open / close the molding cutting area 2.

The rod-shaped food F is guided into the molding cutting area 2 which is constructed as described above and which opens and closes, and at a predetermined position,
The guided rod-shaped food F is formed by appropriately sliding the shutter body 1 to open and close the forming and cutting region 2. The control motor 4, the motor control device 6, and the setting device 7 are installed in the apparatus according to the present invention for the accurate opening / closing operation of the molding cutting region 2. The setting values of the rotation direction, the rotation angle, and the rotation speed of the control motor 4 are input to the setting device 7, and the motor control device 6 controls the control motor 4 according to the setting values. Further, the present device is further provided with a detector 5 for detecting the shaft angle of the rotary shaft of the control motor 4 and outputting the detection signal to the motor control device 6.
However, by comparing this detection signal with the setting signal from the setting device 7, the control motor 4 is operated exactly according to the setting value.
The rotational movement of the control motor 4 having the high followability is converted into the linear sliding operation of the shutter body 1, and the molding cutting area 2
The accurate opening / closing operation of is possible.

As described above, by inputting the set value to the setting device 7, the opening / closing timing, the opening / closing amount, and the opening / closing speed of the forming / cutting region 2 can be appropriately set, respectively, and the hanging rod-shaped food F. It is possible to form the bar-shaped food F into various shapes by forming a constriction by crushing to a certain degree at a predetermined position. Molded bar food F
When cutting, the molding cutting region 2 may be completely closed, and the cut molded food is placed by the belt conveyor B which is arranged below and intermittently operates (in FIG. )) It is moved to a predetermined position.

Further, in this embodiment, the forming / cutting mechanism S including the forming / cutting area 2 and the belt conveyor B are provided.
Are appropriately moved up and down by a first cam C ₁ and a second cam C _{2 which} are interlocked with the motor M. Due to this vertical movement, for example, when the stick-shaped food F is formed or cut, the extrusion speed of the stick-shaped food F and the vertical moving speed of the shutter body are synchronized, or the stick-shaped food F is torn by its own weight to expose the core material. To prevent By adjusting the timing and speed of this vertical movement, more various shapes can be formed on the stick-shaped food F. In addition,
An elevating rod R that supports the belt conveyor B is provided with an adjusting bolt mechanism, and by rotating the adjusting dial A of this adjusting bolt mechanism, the position of the belt conveyor B is adjusted according to the height of the food to be formed. Can be adjusted.

(Manufacturing Process) A manufacturing process in which the apparatus of this embodiment continuously molds and cuts the rod-shaped food F in the molding cutting region 2 will be specifically described with reference to FIGS. 3 to 9. To do.

First, a cored bar-shaped food F made of two kinds of food materials (core material f ₁ and outer skin material f ₂ ) is continuously extruded into the molding cutting region 2 surrounded by the shutter body 1 ( (See FIG. 3). When the stick-shaped food F is pushed to a predetermined position, the shutter body 1 slides by an appropriate amount to close the molding / cutting area 2 and crush the stick-shaped food F to some extent (see FIG. 4). Immediately after the crushing, the control motor rotates in the reverse direction, the shutter body 1 slides in the opposite direction, and the molding cutting area 2 opens.
At this stage, one constricted portion is formed on the rod-shaped food F (see FIG. 5). Then, after waiting for the rod-shaped food F to be extruded again to some extent, the shutter body 1 then slides until the molding cutting region 2 is completely closed, and the rod-shaped food F is cut. In this way, the dharma type food having the constricted portion in the center is molded and cut (see FIGS. 6 and 7).

The belt conveyor B (see FIG. 7) whose height is adjusted in advance by the adjusting dial A moves up to support the food material during the molding and cutting of the rod-shaped food F,
Simultaneously with the completion of cutting, the manufactured dharma type food is placed and lowered. Subsequently, the intermittently operating belt B ₁ is activated to carry the dharma type food (FIGS. 8 and 9).
reference). By repeating such steps, dharma type foods are continuously manufactured.

The shaped food produced by the device of the present invention is not limited to the dharma type, and foods of various shapes can be produced. Some of the variations will be described with reference to FIG. For example, of course, by changing the formation position of the constricted portion with respect to the extruded bar-shaped food, the ratio of the dharma-type head to the body can be changed (see (a) in FIG. 10). By forming a plurality of the constricted portions, it is possible to form a skewer dumpling type (see (B) of FIG. 10) or a shape such as (C) of FIG.

Further, during molding of the constricted portion (see FIG. 4), the shutter body closed to some extent is not opened immediately but kept in that state for a while, and the stick-shaped food is extruded at the upper portion of the constricted portion. By increasing the diameter of the portion, and repeating this several times, it is possible to obtain a food having a complicated form shown in (d) of FIG.

When the above-mentioned dharma type food is cut (see FIG. 7).
In the above), if the belt conveyor B is raised more than supporting the food being cut, the dharma type food can be compressed in the vertical direction, and the kagamimochi type food (see (e) in FIG. 10) is produced. Further, at this time, if the operation of the belt B ₁ is combined, the upper part and the lower part of the constricted portion can be laterally displaced, and a bird shape (see (f) in FIG. 10) can also be formed. Of.

Further, although FIG. 10 shows an example of a food product made from a round bar-shaped food product, the mouthpiece of the extruder from which the food product is extruded may be replaced with various shapes such as a flower shape, a diamond shape, a star shape, or the like. In the middle of the conveyor B conveyor path, add an additional device to add another food material,
By putting hat-shaped food on the above-mentioned dharma-type food, putting mandarin-shaped food on kagami-mochi-type food, or attaching beak-shaped food to bird-shaped food, it is possible to obtain more diverse molded foods. Become.

(Second Embodiment) Next, the device of the second embodiment of the present invention will be described with reference to FIG. Note that FIG.
Shows only the forming and cutting mechanism in the second embodiment device, other configurations of the second embodiment device, for example, an extruder for extruding stick-shaped food, and control of a control motor that is a driving force source of the shutter body. Means and the like are similar to those of the first embodiment.

The molding cutting area in the second embodiment is composed of four rectangular shutter bodies 8/8/8/8. Each shutter body is pivotally supported in a slidable state so as to be rotatable about a pivot pin 8b, a circular cutter hole 8a is formed on the operating end side, and a first link 8c is provided on the force end side. Are connected to each other. Then, one of these four first links 8c, 8c, 8c, 8c is connected to the control motor 4 via the crank mechanism 9.

The forming / cutting mechanism of the second embodiment has the above-mentioned structure, and when the control motor 4 rotates forward / reversely, each shutter body 8 appropriately pivots about the pivot pin 8b. As a result, the cutter hole 8a formed in each shutter body is displaced and the molding cutting area is closed (see (b) of FIG. 10). Also, the cutter holes 8a are aligned and the molding cutting area is fully opened. To do. The formation of the constricted portion is performed by appropriately controlling the rotation direction, rotation angle, rotation start and rotation end time of the control motor.

The embodiment which is a specific example of the present invention is constructed as described above, but the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the claims. Is possible.

For example, according to various characteristics such as tackiness and elasticity of various foods to be processed and shapes to be molded,
It is needless to say that the shape of the shutter body, particularly the shape of the cutter side or the cutter hole, may be appropriately changed, and in the above embodiment, the molding cutting mechanism portion including the molding cutting region, which is arranged only one step, This molding and cutting mechanism part can be moved up and down so that it can be formed into a two-stage or three-stage molding device by stacking a plurality of products, or can be formed and cut diagonally for continuously extruded rod-shaped food products. Instead, it is possible to manufacture a wider variety of molded food products by configuring the food product so that it can be tilted.

Further, in the first embodiment, in order to more smoothly convert the rotational movement of the control motor into the sliding movement of each shutter body, as shown in FIG. 12, two shutter bodies facing each other are used. The linear motion force may be applied simultaneously to In this modified example, shafts 3b and 3e having opposite screw directions are used, such that one shaft has a right-handed screw and the other has a left-handed screw, and the rotation of these two shafts is used as a rotational power transmission means. The chain N is used to accurately synchronize.
