Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food molding method and apparatus, and more specifically, a food molding method and a food that can reliably wrap and mold inner materials such as rice cakes, cooked meat and vegetables with outer skin materials such as bread dough and bun dough The present invention relates to a molding apparatus.
[0002]
[Prior art]
Conventionally, as a technology related to food molding that wraps inner materials such as rice cakes, cooked meat and vegetables with outer skin materials such as bread dough and bun dough, the inner material is made into a rod shape and the outer skin material is cylindrical It is continuously formed, and is formed and cut by narrowing down by opening / closing operation of a shutter mechanism (for example, Japanese Utility Model Publication No. 63-29433). However, when fermentable dough, such as bread dough, is used as the outer skin material, forming it into a cylindrical shape applies excessive pressure, twisting, etc. to the outer skin material, so that the dough does not swell sufficiently after forming and cutting, and the outer skin material is elastic. In the current situation, the molding process is done manually.
[0003]
There has also been proposed a method of forming food with a sheet-like skin material while avoiding the tubular formation of the skin material. For example, Japanese Utility Model Publication No. 7-18299 describes that bread dough and straw are put in a cup and the bread dough is sealed by a sealing gate. In JP 2000-50854 A, an outer packaging material is formed in a bowl shape along an inner wall surface of a cup-shaped female mold whose upper surface is open, and the inner material is supplied into the outer packaging material formed in this bowl shape. Thereafter, the upper edge portion of the outer packaging material is squeezed with a shutter composed of a plurality of shutter pieces to seal the upper edge portion of the outer packaging material and wrap the inner material. When the outer wrapping material is squeezed and sealed with the shutter piece, a plug is disposed in the female opening to prevent the squeezed outer wrapping material from protruding upward.
[0004]
[Problems to be solved by the invention]
As described above, when forming with a sheet-like skin material, for example, because it has flexibility like bread dough, the shape of the skin material is often not constant, and it has an elliptical shape that varies slightly one by one In addition, since the fabric is sticky, it is necessary to consider that the misalignment may occur in the middle of conveyance and it cannot be accurately placed at the molding position. In the conventional food molding method using the above-described sheet-shaped skin material, if the skin material is elliptical or the skin material is supplied to a position shifted from the molding position, the skin material may not be sealed. Cheap. For example, in Japanese Utility Model Publication No. 7-18299, if the dough piece is not placed on the periphery of the cup, the edge portion of the dough piece falls in the subsequent process and cannot be sealed. In order to avoid this, it is conceivable to increase the size of the fabric piece. In this case, since the amount of the fabric piece increases, the fabric piece may protrude when the sealing gate is closed.
[0005]
The same can be said in Japanese Patent Application Laid-Open No. 2000-50854. Although the plug is used to prevent the outer skin material from protruding, if the amount of fabric at the upper edge of the hook-like outer skin material is small, the outer skin material should be removed. In some cases, sealing cannot be performed reliably, and the inner material is exposed and the wrapping becomes incomplete. In fact, when the outer skin material is formed in a bowl shape, the amount of the outer skin material usually varies even when viewed only at the peripheral edge. Therefore, in this conventional apparatus, the upper edge material of the outer skin material is varied. There was no choice but to increase the amount, and the sealing part of the outer skin material tended to be thicker than necessary. In addition, since the plug is disposed, there is a possibility that a problem may arise in terms of mass production such that the number of processes increases and the process becomes complicated, for example, the female mold on which the outer skin material is placed is moved.
[0006]
The present invention was made in view of the above-mentioned difficulties in the conventional food molding apparatus, and the variation in the shape and position of the outer skin material, and the amount of dough at the edge of the outer skin material were compared. It is an object of the present invention to provide a food molding method and apparatus capable of reliably wrapping and molding an inner material with a skin material even if it is slightly dispersed.
[0007]
[Means for Solving the Problems]

[0021]
Hereinafter, the food molding process performed by the food molding apparatus according to the first embodiment will be described with reference to FIGS. FIGS. 5A to 13A are plan views of the first shutter and the second shutter in the respective steps shown in FIGS. 5B to 13B. In the present embodiment, an example in which bread dough is used as the skin material F and rice cake is used as the inner material G will be described.
[0022]
First, as shown in FIG. 5, the sheet-like outer covering material F is placed on the shutter piece 20 of the second shutter 2 with the first shutter 1 opened and the second shutter 2 closed. The shape of the outer skin material F is elongated by a roller to have an elliptical shape, and the inner material G is supplied in advance on the outer skin material. In this embodiment, in order to stably place the outer skin material F on the shutter piece 20, the outer skin material F is placed with the second shutter 2 closed. The skin material F may be placed with the material F opened so as not to fall. Further, after placing the outer skin material F on the shutter piece 20 and operating the shutter piece 10 of the first shutter 1 in the closing direction so as to reduce the opening area, the outer skin material F is adapted to the reduced opening state. The outer skin material F can be set and the position of the outer skin material F can be adjusted so that the outer skin material F is in a predetermined position.
[0023]
Next, as shown in FIG. 6, with the second shutter 2 opened to such an extent that the outer skin material forming means 3 can enter, the upper holding means 4 is lowered to hold the outer skin material F with the presser member 43. The peripheral edge is pressed and held on the shutter piece 20 of the second shutter 2. That is, the holding means 4 is lowered to bring the holding member 43 into contact with the peripheral edge portion of the outer skin material F, and the holding means 4 is further lowered to narrow the gap between the holding member 43 and the stay 41 and the coil spring 44. , And the pressing member 43 is pressed against the peripheral edge of the outer skin material F using the biasing force of the coil spring 44 to hold the outer skin material F on the shutter piece 20.
[0024]
Next, as shown in FIG. 7, the skin material forming means 3 is raised while sucking in the air holes 30 of the forming member 31, and the forming member 31 of the skin material forming means 3 enters the opening of the second shutter 2. By doing so, the center portion of the lower surface of the outer skin material F on the shutter piece 20 of the second shutter 2 is adsorbed and held.
[0025]
Then, as shown in FIG. 8, with the holding means 4 holding and holding the peripheral edge portion of the outer skin material F, the outer skin material forming means 3 while the lower surface central portion of the outer skin material F is adsorbed and held by the outer skin material forming means 3. Is lowered and the forming member 31 of the skin material forming means 3 is withdrawn from the opening of the second shutter 2, so that the central portion of the skin material F is recessed to form the skin material F in a bowl shape. At this time, the inner material G supplied in advance on the outer skin material F descends together with the central portion of the outer skin material as the outer skin material is formed in a hook shape, and is arranged at the bottom of the hook-shaped outer skin material. Thereafter, as shown in FIG. 9, the holding means 4 is raised to separate the pressing member 43 from the peripheral edge portion of the outer skin material F.
[0026]
Next, as shown in FIGS. 9 and 10, as the first shutter process, the peripheral portion of the outer skin material F positioned on the shutter piece 20 of the second shutter 2 is closed by operating the first shutter 1 to close the inner material. Collect to wrap G. As described above, in the present embodiment, the plurality of shutter pieces 10, 10... Can move horizontally from the outside toward the center, and the peripheral portion of the outer skin material F can be gathered along the inner material G in the middle. The inner material G can be wrapped with the outer skin material F while releasing the air between the material F and the inner material G.
[0027]
Then, as shown in FIGS. 11 and 12, as the second shutter process, the second shutter 2 is closed while the first shutter 1 is closed, so that the peripheral portion of the collected outer skin material F can be reliably secured. The molded product H is obtained by sealing and enclosing the inner material G with the outer skin material F. When sealing the peripheral edge of the skin material F with the second shutter 2, the shape of the molded product H is positively adjusted by appropriately moving the skin material forming means 3 up and down to adjust the distance from the second shutter 2. It is also possible to shape manually.
[0028]
Thereafter, as shown in FIG. 13, the tip of the forming member 31 of the outer skin forming means 3 is reversed from the upper side to the lower side while the molded product H is adsorbed and held, and blown from the vent holes 30, 30. The product H is separated from the forming member 31 and placed on the conveyor 5 to convey the belt.
[0029]
As described above, according to the present embodiment, first, the first shutter 1 collects the peripheral portion of the outer skin material F (see symbol A in FIG. 10B), and then the lower second shutter 2 collects the collected portion ( Since the peripheral portion of the outer shell material F (see reference symbol B in FIG. 10B) different from the reference symbol A in FIG. 10B is further collected and sealed, Even if the amount of fabric at the peripheral edge of F is small or varies, the amount of fabric necessary for sealing is secured by collecting the outer skin material by the first shutter 1 and further collecting by the second shutter 2. The periphery of the outer skin material can be reliably sealed, and the inner material is not exposed. Similarly, even if there are variations in the shape of the outer skin material and positional deviation, the outer skin material is collected by the two closing operations of the first shutter 1 and the second shutter 2 as described above, so that the sealing operation can be performed more reliably. It can be carried out.
[0030]
Further, as shown in FIG. 11B, when the peripheral portion of the outer skin material F is sealed with the second shutter 2, if the first shutter 1 is closed, the outer skin material F is second when sealed. It can be neatly wrapped and molded without losing the outer skin material without protruding above the shutter 2.
[0031]
Further, according to the present embodiment, the center portion of the sheet-like outer skin material is held by the outer skin material forming means 3 that has entered the shutter opening portion, and the outer skin material forming means 3 is retracted from the shutter opening portion to thereby make the outer skin. Since the material is formed in a bowl shape, it can be formed in a bowl shape with almost no damage to the outer skin material, and a high-quality molded product can be obtained. Furthermore, since the outer material forming means 3 and the inner material G on the outer skin material F can be formed in a bowl shape, the inner material G adheres to the outer skin material forming means 3 and may cause sanitary problems. Nor.
[0032]
Further, as in the present embodiment, if the forming member 31 of the covering material forming means 3 is held by adsorbing the central portion of the covering material, and the molded product is released by the fumes from the forming member 31, The molded product can be transferred to the conveyor 5 reliably and quickly.
[0033]
Further, as shown in FIGS. 14 and 15, a thin plate 6 is sandwiched between the first shutter 1 and the second shutter 2 as a receiving member for receiving the outer skin material F, and the thin plate 6 is shown in the plan view of FIG. If the opening 60 is provided, the outer skin material F can be securely held by the thin plate 6 and the pressing member 43 of the holding means 4 and the forming member 31 of the outer skin forming means 3 that has entered the opening 60 can be provided. Then, the outer skin material F is adsorbed and held, and the forming member 31 is withdrawn from the opening portion 60, whereby the outer skin material can be formed in the thin plate 6 by using the opening portion 60.
[0034]
[Second Embodiment]
The food molding apparatus of the second embodiment shown in FIG. 17 is characterized in that the holding means for holding the edge of the outer skin material on the shutter is omitted to simplify the apparatus configuration and the food molding process. The other configurations are the same as those of the first embodiment described above, and the same reference numerals as those of the first embodiment are attached and the description thereof is omitted. Hereinafter, the food molding process by the second embodiment apparatus will be described with reference to FIGS.
[0035]
First, as shown in FIG. 18, the sheet-like skin material F is placed on the shutter piece 10 of the first shutter 1 with the first shutter 1 and the second shutter 2 opened. The inner material G is supplied in advance on the outer skin material. Here, the skin material F is supplied in a state where the first shutter 1 is opened to such an extent that the skin material F does not fall, but the skin material F is supplied with the first shutter 1 closed. Alternatively, with the first shutter 1 and the second shutter 2 opened, the forming member 31 of the outer skin forming means 3 described below is raised in advance, and then the shutter piece of the first shutter 1 is moved. 10 and the outer member F may be placed on the forming member 31. The outer skin material F can be mounted more stably by these things.
[0036]
Next, as shown in FIG. 19, the skin material forming means 3 is raised while sucking in the air holes 30 of the forming member 31, and the forming member 31 enters the openings of the first shutter 1 and the second shutter 2. As a result, the center portion of the lower surface of the outer skin material F on the shutter piece 10 of the first shutter 1 is adsorbed and held. Then, as shown in FIG. 20, the outer skin material forming means 3 is lowered while the central portion of the outer skin material F is sucked and held, and the forming member 31 of the outer skin material forming means 3 is withdrawn from the opening of the second shutter 2. Thereby, the center part of the outer skin material F is dented and the outer skin material F is formed in a bowl shape. At this time, the inner material G supplied in advance on the outer skin material F descends together with the central portion of the outer skin material as the outer skin material is formed in a hook shape, and is arranged at the bottom of the hook-shaped outer skin material.
[0037]
Then, as in the first embodiment described above, as the first shutter process, as shown in FIG. 21, the peripheral portion of the outer skin material F is collected so as to wrap the inner material G by closing the first shutter 1, and As the second shutter step, as shown in FIGS. 22 and 23, the peripheral portion of the outer skin material F collected by closing the second shutter 2 with the first shutter 1 closed is securely sealed. Then, a molded product H in which the inner material G is wrapped with the outer skin material F is obtained, and then the tip of the forming member 31 of the outer skin material forming means 3 is directed downward from above while the molded product H is held by suction as shown in FIG. The molded product H is separated from the forming member 31 by being blown from the air holes 30, 30, and placed on the conveyor 5 and conveyed by a belt.
[0038]
In the present embodiment, a sheet-like outer skin material F is placed on the shutter piece 10 of the first shutter 1 and the outer skin material forming means 3 is inserted into the openings of the first shutter 1 and the second shutter 2. Although the outer skin material is formed in a bowl shape by sucking and holding the outer skin material F and withdrawing it from the shutter opening, the present invention is not limited to this, and the outer skin material F is used as the shutter of the second shutter 2. The outer skin material F is adsorbed and held by the outer skin material forming means 3 which is placed on the piece 20 and held in the opening of the second shutter 2 without holding the edge portion of the outer skin material F on the second shutter 2. Then, the outer skin material may be formed in a bowl shape by being withdrawn from the shutter opening. If the outer skin material F is placed on the second shutter 2 in this way, the shutter piece 10 of the first shutter 1 is placed so that the outer skin material F is in a predetermined position as in the first embodiment described above. The position of the outer skin material F can be adjusted by swinging.
[0039]
In the above embodiment, the skin material forming means 3 is lowered to form the skin material F in a bowl shape, and then the first shutter 1 is closed and the first shutter process is performed. The first shutter process may be started in the middle of the lowering of the skin material forming means 3. In this way, when viewed with the inner material G as a reference, the shutter piece 10 of the first shutter 1 closes while being relatively lifted, so the shutter piece 10 is moved along the inner material G. Thus, it is possible to continuously perform the hook-like forming action of the skin material and the gathering action of the peripheral edge portion of the skin material, and the inner material G can be wrapped more smoothly.
[0040]
As described above, in this embodiment, since no holding means for holding the outer skin material on the shutter piece is provided, the apparatus can be simplified correspondingly, and the process can be simplified and the speed can be improved. Can do.
[0041]
And also in this embodiment, since the peripheral part of the outer skin material F is collected by two closing operation | movement of the 1st shutter 1 and the 2nd shutter 2 similarly to 1st embodiment, sealing operation is performed more reliably. Can do. Further, as shown in FIG. 22, when the peripheral portion of the outer skin material F is sealed with the second shutter 2, if the first shutter 1 is in the closed state, the outer skin material F of the second shutter 2 is sealed at the time of sealing. It does not protrude upward and can be encased and molded neatly without loss of the outer skin material. Further, the center part of the sheet-like outer skin material is held by the outer skin material forming means 3 that has entered the shutter opening, and the outer skin material forming means 3 is retreated from the shutter opening to form the outer skin material in a bowl shape. Therefore, it is possible to form a hook-like shape with almost no damage to the outer skin material, and to obtain a high-quality molded product.
[0042]
The food molding method and its apparatus according to the present invention are not limited to these embodiments, and various design changes can be made within the scope of the claims.

For example, in the above embodiment, four shutter pieces are used as the first shutter 1 and the second shutter 2, but the number of shutter pieces is particularly limited as long as it is possible to collect the outer skin material. The number of shutter pieces may be different between the first shutter 1 and the second shutter 2, and the position of the swing axis of the shutter pieces of the first shutter 1 and the second shutter 2 may be different. The shutter drive means employs a drive mechanism that opens and closes as each shutter piece reciprocally swings around the drive shaft. However, the present invention is of course not limited to this, for example, FIG. As shown in FIG. 26, each shutter piece 101 is opened / closed by sliding linearly in the direction of the arrow, and as shown in FIG. 26, each shutter piece 102 is rotated by the action pin 103 in the arrow direction. Accordingly, various drive mechanisms such as a drive mechanism that opens and closes by swinging while linearly moving can be used. Different shutter mechanisms may be employed for the first shutter 1 and the second shutter 2. Further, regarding the shape of each shutter piece, various shapes such as those having a straight side as shown in FIG. 25 or FIG. Can do.
[0044]
Further, in the above embodiment, the first shutter 1 and the second shutter 2 are disposed so as not to have a gap. However, it is not always necessary that the both have a gap, and at least the peripheral portion of the outer skin material is used. When sealing with the second shutter, if there is no gap between the first shutter 1 and the second shutter 2, it is possible to prevent the outer shell material from protruding, so the positional relationship between the first shutter 1 and the second shutter 2 is as described above. It is not limited to the embodiment. If there is no risk of food entering the gap when sealing the outer skin due to the properties of the outer skin, etc., the first shutter 1 and the second shutter 2 do not necessarily have to be in contact with each other. Absent. Furthermore, in the above embodiment, the first shutter 1 and the second shutter 2 are both in a flat state when they are closed. However, if it is possible to collect the skin material, each shutter piece has a curved shape. Also, when closed, the surface does not have to be formed, and various design changes are possible.
[0045]
In the above embodiment, the second shutter 2 is closed after the first shutter 1 is completely closed. However, the closing operation of the second shutter 2 is started before the first shutter 1 is completely closed. Alternatively, the drive timing of the first shutter 1 and the second shutter 2 can be variously changed in consideration of the properties of the outer skin material and the like, and is not limited to the above embodiment.
[0046]
In the above embodiment, the inner material G is supplied on the outer skin material F in advance, and the outer skin material F is formed in a bowl shape as it is, so that the inner material G is formed at the bottom of the outer shell material F formed in the bowl shape. However, for example, after the outer skin material F is formed into a bowl shape, the inner material G may be supplied to the bottom of the outer shell material F formed in the bowl shape. The supply is not limited to the above embodiment.
[0047]
In the above embodiment, only one set of the first shutter 1 and the second shutter 2 is provided, but a plurality of sets may be provided as shown in FIG. In FIG. 27, two sets of the first shutter and the second shutter shown in FIGS. 2 to 4 are arranged in parallel, the first shutter 111 and the second shutter 112, the first shutter 113, and the second shutter 114. Yes. The drive shafts of two sets of adjacent shutter pieces are shared, and the adjacent shutter pieces are swung by one drive shaft. The outer material forming means such as the forming member described in the above embodiment, the holding means such as the pressing member, and the like may be provided according to the number of sets to be arranged. If the drive shafts of a plurality of sets of adjacent shutter pieces are made common in this way, three or more sets can be arranged in parallel, and a plurality of molding processes can be performed simultaneously. Therefore, the production efficiency is greatly improved, and the structure of the apparatus can be simplified by using a common drive shaft, and further downsizing can be achieved.

【The invention's effect】
As described above, in the food molding method and apparatus according to the present invention, first, the first shutter collects the peripheral portion of the outer skin material, and then the second shutter further collects the outer skin material. Since the peripheral edge of the material can be securely sealed, even if there is a variation in the shape or positional displacement of the outer skin material, even if the amount of fabric on the peripheral edge of the outer skin material is small or varies, The first shutter and the second shutter collect the peripheral edge of the outer skin material to secure the amount of fabric necessary for sealing, so that the peripheral edge of the outer skin material can be reliably sealed and the inner material is exposed. There is no end to it.
[0049]
In addition, the central portion of the skin material is retained by holding the central portion of the sheet-like outer skin material with the outer skin material forming means that is relatively entered into the shutter opening, and withdrawing the outer skin material forming means relatively from the shutter opening. Since the outer skin material is formed in a bowl shape by recessing the portion, it can be formed in a bowl shape with almost no damage to the skin material, and a high-quality molded product can be obtained. Further, if the first shutter is closed when the outer cover material is sealed by the second shutter, the outer cover material does not protrude above the second shutter, and the outer cover material can be neatly wrapped and molded. Furthermore, since the wrapping is performed by two shutters, it is mechanically compact as compared with the prior art, the food conveying path is greatly shortened, and the molding process can be performed at a high speed.
[0050]
Also, if the outer skin material is supplied onto the shutter piece of the second shutter with the first shutter opened, a series of operations such as supply-forming-molding can be performed without moving the outer skin material, and more reliably and High-speed processing is possible. Furthermore, if the outer shell material is supplied onto the shutter piece of the second shutter and then the position of the outer skin material is adjusted by the first shutter, the variation in the shape of the outer skin material or the positional deviation is corrected in advance, and a more reliable molding process is performed. be able to. Further, by holding the edge portion of the outer skin material on the shutter piece of the second shutter, it is possible to more reliably form the outer skin material in a bowl shape. Furthermore, if a receiving member for receiving the outer skin material is provided between the first shutter and the second shutter, the edge portion of the outer skin material can be more reliably held. Furthermore, if the inner material is arranged in the outer skin material before forming the outer skin material into a bowl shape, the inner material can be wrapped and molded more reliably and at high speed. Furthermore, if the first shutter process is performed while the outer skin material is formed in a bowl shape, it can be more smoothly wrapped and molded.
