DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a bi-folded food product which is made by bi-folding rice cake dough or the like and is capable of producing a bi-folded food product such as a kashiwa mochi, and a bi-fold food product used for this method. It relates to an improvement of the device.

[0002]

2. Description of the Related Art In order to manufacture a kashiwa mochi, it is necessary to fold the spread mochi dough or the like in two while sandwiching the bean paste inside. At present, as a device for automatically performing this bi-fold molding instead of manual work, those described in JP-B-60-12011 and JP-B-60-13655 are known. These use several sets of two forming plates each having a concave forming portion on the upper surface. After these two forming plates are horizontally arranged in parallel on the same plane,
After the spread mochi dough is placed on these molding plates, the mochi dough is folded in two by valley-folding the two molding plates at the facing parts so that the concave molding parts face each other. It is a thing.

In order to realize the valley folding operation of this forming plate, the apparatus of Japanese Patent Publication No. 60-12011 connects two forming plates with a hinge and moves the connected forming plate assembly by a conveyor. A means is adopted in which one of the forming plates is brought into contact with the guide plate to be folded down to the other forming plate. However, in this device, when the valley-folded forming plate assembly returns to the original food loading state, the forming plate assembly performs an unfolding operation that is completely opposite to the valley folding operation. However, it was not very practical because it had the drawback that the mochi dough adhered to the molding plate and the food folded in half opened again.

On the other hand, in Japanese Patent Publication No. Sho 60-13655, in order to realize the valley folding operation of the forming plates, a plurality of forming plates, one set of two, are provided on the circumference of a pair of left and right rotating bodies which make mutually opposite rotational movements. Each of them is hinge-coupled to each other, and while swinging the forming plate with these rotating bodies, the left and right forming plate swinging ends are slidably moved on the left and right guide cams, so that the left and right forming plates have symmetrical valley folds. It employs a means of performing an operation. In the case of this device, when releasing the folded food, the two molding plates are configured to show the folded food from the back side first. It was possible to automatically manufacture Kashiwa-mochi without any problems in development, and we could see a significant improvement in the production efficiency of Kashiwa-mochi or food hygiene.

However, in this Japanese Patent Publication No. Sho 60-13655, since a large number of forming plates and the rotating bodies that drive them are connected by a fine hinge mechanism one by one, a large force is applied to these hinge connecting portions during operation. As a result, there is a drawback in that rattling is likely to occur at these hinge connection parts, there are many failures, and the life of the device is short. Moreover, if the operating speed is increased to improve the production efficiency, the hinged molded plate will immediately flutter, which is not suitable for high speed operation.

Further, in this device, since the rotary support shaft of the rotating body for driving the forming plate is positionally fixed, for example, when the thickness of the food material to be folded in two is different,
When changing the intervals between the molding plates, it is troublesome to adjust the positions of various parts and replace them.

[0007]

The present invention has been made in view of the above-mentioned problems in the conventional two-fold food manufacturing apparatus, and includes left and right forming plates for performing a food two-fold operation, Since it is not necessary to provide a movable mechanism such as a hinge connection between the rotating body that drives these forming plates, high-speed and stable execution is possible, and further, the left and right forming during food folding operation. It is a technical object to provide a method for producing a folded food product in which the plate interval can be easily changed.

Another technical problem of the present invention is that it is suitable for high-speed operation because the device mechanism is simple, the number of movable parts is relatively small, and no sliding mechanism has to be considered in consideration of wear and the like. Another object of the present invention is to provide a bi-fold food manufacturing device having a long device life.

It is configured to perform a swinging motion while always maintaining a symmetrical relationship.

The left and right swing arms 5A and 5B are respectively provided with a pair of left and right rotary support shafts 3A and 3 via bearings 52A and 52B so that the tip ends of the shafts project to the outside of the housing H.
B is provided, and these left and right rotary support shafts 3A and 3B are provided.
A pair of left and right rotating bodies 2A and 2B are fixed to the tips of the
On the other hand, a pair of left and right driven gears 84A and 84B, and a pair of left and right swing cams 4A and 4 are provided at the rear ends of the rotary support shafts 3A and 3B.
B is fixed. In addition, the left and right swing arms 5A and 5
A tension coil spring is stretched between the swinging ends of B as the indexing means 51, and the indexing means 51 always urges the left and right swing arms 5A and 5B toward each other. The rocking cams 4A and 4B of the same shape always abut symmetrically.

With this configuration, the left and right rotary support shafts 3A
If 3B rotate in opposite directions, the rotor 2A
・ At the same time as 2B rotate in opposite directions, rocking cams 4A ・ 4
B also makes reverse rotational movements in a state in which they are pressed against each other by the indexing means 51, and the left and right swing arms 5A and 5B described above are rotated by the swing cams 4A and 4A as shown in FIGS.
According to the cam shape of B, the open / close swing motion is performed while maintaining the bilateral symmetry. In other words, the device of this embodiment is
Since the pair of left and right rotating bodies 2A and 2B are reversely rotated by the reverse rotation motion of the rotary support shafts 3A and 3B, the distance between the rotary shafts (the rotary support shafts 3A and 3B) is changed according to the rotation angle. is there.

The reverse rotational movement of the rotary support shafts 3A and 3B is
This is performed by the motor 8 fixed to the support frame 9. That is, as shown in FIG. 3 and FIG. 4, the driving force of the motor 8 is generated by the drive gear 81, first through the bearings 82A and 82B, the pair of left and right transmission gears 83A.
The reverse rotation driving force is transmitted to 83B as a reverse rotation driving force, and further, the reverse rotation driving force from each of the transmission gears 83A and 83B is fixed to the rotation supporting shafts 3A and 3B.
By being transmitted to 84B, the left and right rotary support shafts 3A
3B rotate in opposite directions.

Further, in the figure, what is indicated by reference numerals 1A and 1B are molded plates symmetrically mounted on the left and right rotating bodies 2A and 2B, respectively, and in this embodiment, these molded plates 1A and 1B. Three 1Bs are provided on the left and right rotating bodies 2A and 2B at intervals of a central angle of 120 ° (Fig. 6).
), Semi-circular recesses 11A and 11B are formed at the plate tips on the opposite sides of the mounting portions of these molding plates 1A and 1B, respectively.

As described above, in the apparatus of this embodiment, the left and right molding plates 1A and 1B are mounted on the left and right rotating bodies 2A and 2B without using a movable mechanism such as a hinge connecting mechanism. In the case of the device of this embodiment, the left and right rotating bodies 2A
The rotation support shafts 3A and 3B move away from each other in response to the synchronous rotation of 2B from the upper side to the lower side, so that the molding plate and the rotating body that drives the molding plate swing as in the conventional device. It is not necessary to perform hinge connection as much as possible, and the left and right molding plates 1A and 1B can be made to perform a symmetrical valley folding operation while keeping the plate spacing substantially constant. By the valley folding operation of the molding plates 1A and 1B, the food material F placed on the molding plates 1A and 1B is continuously folded in two.

The interval between the left and right molding plates 1A and 1B during the valley folding operation is the shape and size of the left and right rocking cams 4A and 4B that rotate in opposite directions in a state of being pressed against each other. (See FIGS. 6, 8 and 9). Therefore, in the device of this embodiment, the swing cams 4A and 4A

Further, since the left and right swing cams 4A and 4B abut and rotate at the same speed during operation and never slide on each other, the life of the device is shortened due to abrasion of the sliding mechanism portion as in the conventional device. Nothing.

[0022] "clamshell food production process" Next, actual food material F was molded clamshell is the embodiment device, the continuous process slide into manufacturing Folded food F _1,
This will be described with reference to FIGS.

The apparatus of this embodiment is composed of the left and right molding plates 1A.
・ In a state where the 1Bs are horizontally arranged side by side on the same plane,
It stands by until the conveyor C ₃ conveys the food material F (rice cake dough in this embodiment) on which the bean paste f is placed (see FIG. 10). Then, the food material F on which the bean paste f is placed is the forming plate.
At the moment when it is conveyed above 1A and 1B, conveyor C ₃
Quickly retracts, and food material F has left and right molded plates 1A
-Placed on 1B (see Figure 11). The forward / backward movement mechanism of the conveyor C ₃ is well known in the art, and the function is obtained by adopting an air cylinder mechanism .

After the food material F is placed on the molding plates 1A and 1B, the left and right rotating bodies 2A and 2B are opposed to each other while keeping their axial distances (that is, the distances between the rotation supporting shafts 3A and 3B). On the side, rotation is performed from the top to the bottom at the same speed, and the symmetrical valley folding operation by the left and right forming plates 1A and 1B is started (see FIG. 12). This forming plate 1A ・ 1
As the valley folding operation of B progresses, the food material F is gradually folded in two.
From the time point when A.1B is rotated by about 45 °, the rotating bodies 2A and 2B driving the forming plates 1A and 1B continue the rotating motion while reducing the axial distance (Fig. 13,
(See Figure 14).

Then, the left and right molding plates 1A and 1B
However, the food material F is completely folded in half and formed into a half-folded food F ₁ at the time when the food materials F are arranged in parallel with each other at a predetermined interval determined by the swing cams 4A and 4B (not shown) ( (See Figure 15). After the food material F was molded clamshell, further continues to rotate the rotating body 2A · 2B, molding plates 1A · 1B is so on are披展first from the back side of the clamshell food F _1, molded clamshell food F ₁ is dropped onto the conveyor C ₄ arranged below (see FIG. 16).

The folded bi-fold food F ₁ is conveyed by the conveyor C ₄
While being conveyed to a predetermined position by this, the other pair of molding plates 1A and 1B are lined up on the same plane, and wait for the food material F to be processed next to be conveyed (Fig.
17).

Although the method for producing a folded food product according to the present invention and the apparatus for producing a folded food product using this method have been specifically illustrated by the above embodiments, the present invention is limited to these embodiments. It is possible to make various modifications within the description of "Claims" rather than the description.

For example, in this embodiment, the axial distance between the left and right rotating bodies 2A and 2B (distance between the rotary support shafts 3A and 3B).
As means for changing the oscillating arm, the oscillating cams 4 that rotate in reverse with the rotating bodies 2A and 2B are attached to the oscillating ends of the oscillating arms 5A and 5B.
A cam mechanism is provided in which A and 4B are provided and these rocking cams 4A and 4B are constantly in pressure contact with each other. However, in carrying out the bi-fold food manufacturing method according to the present invention, the axial distance of another mechanism is changed. Of course, means may be adopted. For example, instead of the rocking cams 4A and 4B and the indexing means 51 in the above-described embodiment, a rock-pinion mechanism or a feed screw mechanism which is driven by a drive source different from the motor 8 is used, and the rocking arms 5A and 5B are used. In place of the swinging arms 5A and 5B that perform swinging movements or that perform arcuate movements, the rotation support shafts 3A and 3B may be directly linearly movable by a rack-pinion mechanism or the like. Furthermore, one of the left and right rotary support shafts 3A and 3B may be separated from the other so that the axial distance between the two can be changed according to the rotation angle of the rotating bodies 2A and 2B. It's good.

[0029]

As described above with reference to the embodiments, in the method for producing a bi-folded food product according to the present invention, the pair of left and right rotating bodies provided with the molding plates for folding the food product in two are rotated in reverse to each other. At the same time, since the means for changing the inter-axis distance of these rotating bodies according to this rotation angle is adopted, the forming plates are mounted on the rotating body in order to make the left and right forming plates perform a valley folding operation as in the conventional case. It is not necessary to connect hinges, and therefore, the molded plate does not flutter even if it is carried out at high speed to improve the production efficiency, and the bi-fold food can be manufactured at high speed and stably.

Further, in the method of the present invention, the inclination change of the left and right forming plates is realized by utilizing only the rotational movement of the left and right rotating bodies. Since it is realized by utilizing the separating operation of the left and right rotating bodies, it is possible to change the distance change between the left and right molding plates independently of the plate inclination change. Therefore, for example, even when the thickness of the food material to be folded in two is different, it is possible to easily change the left and right molding plate intervals at the time of folding in two, and easily perform optimum folding for various food materials. You can

Further, in the bi-fold food manufacturing apparatus according to the present invention, the left and right molding plates are securely attached to the left and right rotating bodies, and the swing cam mechanism is highly reliable.
Since the spacing of these molding plates is changed by skillfully utilizing, it is possible to eliminate the sliding mechanism that must consider wear from the drive mechanism of the device .
is there. As described above, the device of the present invention does not employ any sliding mechanism and does not use a movable mechanism such as a hinge connection between the molding plate and the rotating body that drives the molding plate, which enables high-speed operation. Thus, it is possible to stably produce a bi-fold food product for a long period of time.

Further, the device of the present invention is configured such that the left and right rotating bodies are driven to rotate in reverse by only one motor and the separating operation of these rotating bodies is performed without complicating the mechanism. Therefore, it is possible to provide a compact and space-saving two-fold food manufacturing device with a simple device mechanism and few breakdowns, and its industrial utility value is extremely high.
