Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food split molding method and apparatus, and more particularly, to a food split molding method and apparatus for continuously forming and feeding a food material into a rod shape and split molding.

[0002]

2. Description of the Related Art As a food material, for example, an inner material is wrapped inside a skin material and supplied in a rod shape, and the food material continuously formed into a rod shape is divided by a shutter composed of a plurality of shutter pieces to be molded. As described in Japanese Patent No. 2641033, Japanese Patent No. 2696600, etc.,
Already known. In such a food split molding method, when a plurality of shutter pieces are rotated or rocked to squeeze foodstuffs, the outer skin material is divided so as to wrap the inner material following the movement of the shutter pieces. In this case, the movement of the dividing surface of the shutter piece slides so as to twist in the circumferential direction when the cross section of the outer cover material is a circle. Therefore, Japanese Patent No. 2696
As shown in the prior art of Japanese Patent Laid-Open No. 600, a plurality of spiral irregularities such as flower patterns are formed on the divided surface of the outer skin material. That is, the portion pressed and slid by the dividing surface of each shutter piece is recessed, and a band-shaped convex portion is formed at the boundary. When the unevenness is elastic like an outer skin material mainly made of nonglutinous rice, glutinous rice or strong flour, the recessed part returns to some extent after the splitting and the unevenness is reduced, but the soft flour is mainly used. When the outer skin material (for example, chestnut bun, steamed bun, etc.) and bean paste used as the outer skin material is not sticky and has poor elasticity, the unevenness remains almost as it is.
In such a state where the surface is uneven, the appearance is poor and the commercial value is reduced, so that it may be necessary to further roll it manually. In addition, the thickness of the outer cover material becomes uneven due to the unevenness, and if there is a thin portion, the inner material is transparent and a mottled pattern is formed. I had to take action.

In Japanese Patent No. 2696600, the convex sliding surface of each shutter piece is closed and then further slid to a completely closed state to even out the irregularities such as the above-mentioned flower pattern. However, although the protrusions on the top are leveled, it is inevitable that the above-mentioned unevenness remains.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the conventional food split molding apparatus, and it is like a flower pattern formed on the surface of an outer skin material during split molding. It is an object of the present invention to provide a food product split molding method and apparatus capable of smoothing such unevenness and shaping it into a smooth surface.

[0005]

And a shutter driving unit that operates the second shutter to shape the divided surface of the food material. Further, each shutter piece of the second shutter is arranged so as to substantially overlap with each shutter piece of the first shutter in a plan view. Further, each shutter piece of the second shutter is arranged between the shutter pieces of the first shutter in a plan view. Further, the supporting means includes a belt conveyor mechanism. Further, another food product dividing and shaping apparatus according to the present invention is a food product supply means for continuously forming and supplying food products in a rod shape, a first shutter having a plurality of shutter pieces, the first shutter and the food product supply means. A second shutter that is disposed between the first and second shutters and has a plurality of shutter pieces, and operates the first shutter to divide the rod-shaped continuous food material, and shapes the divided surface of the food material. To this end, a shutter driving means for operating the second shutter is provided. Here, the divided surface of the food material means a surface of the food material formed by the closing operation of the first shutter, such as a surface of the food material divided by the first shutter or a surface of the food material continuously formed in a rod shape after the division. , The food surface formed during the operation of the first shutter is also included. By having the above-mentioned configuration, by sliding the shutter piece of the second shutter onto the divided surface of the food material formed by the closing operation of the first shutter, the food material continuously formed in a rod shape Can be shaped. As described above, the flower-pattern-shaped irregularities generated after the food material is divided have a smooth surface because the convex portions are leveled by the sliding of the second shutter.
Further, in the case where the continuously formed rod-shaped food material has a layered structure in which a rod-shaped inner material is wrapped in a tubular outer material, the unevenness of the outer material of the divided food material is leveled to make the thickness substantially uniform. can do. Further, by devising the sliding operation of the second shutter, it is possible to positively change the shape of the divided food material. For example, the sliding operation of the second shutter may be performed so that a protrusion is formed at the center of the food material. It is also possible to operate the second shutter during the operation of the first shutter, and if the second shutter is operated so as to follow the first shutter, the food can be divided and molded in a shorter time. . Further, by sandwiching the food material to be divided before the food material is divided by the closing operation of the first shutter by the shutter piece of the second shutter, the movement of the food material due to the division is suppressed, and the subsequent shaping is performed more stably. You can Then, the first shutter and the second shutter are
Since it can be driven by the same driving means, the driving mechanism can be simplified and the space for disposing the two shutters can be reduced, so that the apparatus can be made compact. Then, by supporting the food material by the supporting means while the divided surface of the food material is shaped by the second shutter, the position of the food material to be divided can be reliably set, and more stable shaping can be performed. Further, by arranging the second shutter between the first shutter and the food material supplying means, the divided surface of the food material continuously formed in a rod shape can be shaped, so that the final bottom surface of the food product can be shaped. In addition to the above, in the case of the layered structure of the inner material and the outer material as described above, it is possible to increase the thickness of the outer material of the bottom surface by sliding the outer material with the shutter piece of the second shutter. .

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments according to the present invention will be described in detail below. [First Embodiment] FIG. 1 is a front view schematically showing the entire food product split molding apparatus. Here, 1 indicates the first shutter and 2 indicates the second shutter. The first shutter 1 is adapted to be opened and closed by a link mechanism 3 described later, and the link mechanism 3 is driven by a drive device 5. Although not shown, the driving device 5 includes a motor that drives the link mechanism 3, a motor control device that controls the motor, a detector, and a setting device. By inputting setting values such as speed, the motor control device compares the detection result from the detector that detects the rotation state of the motor with the input setting value, and controls the motor according to the setting value. I have to. Similarly to the first shutter 1, the second shutter 2 is also configured to be opened and closed by a link mechanism 4 described later, and the link mechanism 4 is driven by a drive device 6. The drive device 6 is similar to the drive device 5 in that it includes a motor, a motor control device, a detector, and a setter. Reference numeral 7 denotes a support means for supporting the food material F, and a support member 70 for supporting the food material F is vertically moved by a rack-pinion mechanism 72 via a support rod 71. If the belt of the belt conveyor is arranged on the support member 70 in the front-back direction (perpendicular to the paper surface), and the food material F is moved up and down by the support member 70 via the belt, the divided food material after split molding is formed. F can be immediately conveyed by a belt conveyor. Reference numeral 8 indicates a mechanism for vertically moving the first shutter 1 and the second shutter 2 as a whole.
An elevating rod 80 fixed to the lower part of a link cover that covers the link mechanism 3 and the link mechanism 4 is moved up and down following a cam 81 that rotates in conjunction with a motor 82. Code 9
Indicated by means is a food supply means for continuously forming and extruding the food F into a rod shape. The extruder 91 is supplied with the inner material, and the extruder 92 is supplied with the outer material. Taking buns as an example, dough containing bean jam and soft flour as the main materials is supplied as the inner material and the outer skin material, respectively. The inner material and the outer skin material are pressure-fed to the extrusion die 90 from each extruder, and as shown in the figure, the inner material is continuously formed into a rod shape and extruded, and the outer skin material is tubular so as to cover the periphery thereof. Is continuously formed and extruded. Here, as the extruder, for example, a vane pump may be used. The mechanism 8 for moving the shutter up and down is
It is controlled so as to move up and down in synchronization with the timing of the pushing operation of the food F from the pushing die 90. By performing the dividing operation of the food material F after moving the shutter upward during the extruding operation, the continuously formed food material F is prevented from being extruded more than necessary and being stretched or torn by its own weight.

FIG. 2 is an enlarged view of the shutter portion of FIG. 1 as seen from the side, and the two shutters are in a closed state. 3 and 4 are plan views of the first shutter 1 and the second shutter 2 in the open state, respectively. In order to facilitate understanding, the drawing is performed by excluding the second shutter 2 and the link mechanism 4 in FIG. 3, and is illustrated by excluding the first shutter 1 and the link mechanism 3 in FIG. 4. As shown in these figures, in this embodiment, the first shutter 1 and the second shutter 2 are respectively composed of four shutter pieces 10 and four shutter pieces 20, and the shutter piece 10
The shutter piece 20 and the shutter piece 20 are arranged to overlap each other in a plan view. FIG. 5 shows an example of the shape of the shutter piece 10. The dividing surface of the shutter piece 10 is a strip-shaped protrusion 10 at the center.
1 is formed, and a slope is formed between the upper and lower surfaces and the protrusion 101. A groove portion 102 is formed at the tip end portion so as to be slidable on the divided surfaces of the adjacent shutter pieces, and an edge portion 103 is formed by intersecting the protrusion portion 101 and the groove portion 102. Similarly, FIG. 6 shows an example of the shape of the shutter piece 20, which has a shape in which the upper portion of the shutter piece 10 is removed along the strip-shaped protruding portion 101 in parallel with the upper surface. The projection 101, the groove 102, and the edge 103 of the shutter piece 10 correspond to the projection 201, the groove 202, and the edge 203, respectively, and a slope is formed between the lower surface and the projection 201. A tubular rotation shaft 11 is fixed to each shutter piece 10 of the first shutter 1, and a rotation provided by being fitted to the rotation shaft 11 is provided to each shutter piece 20 of the second shutter 2. The shaft 21 is fixed. Each rotating shaft 11
A flange 12 is fixed to the end portion on the opposite side to the shutter piece 10 is also rotated when the flange 12 is rotated. The shutter piece 20 is the shutter piece 10.
A flange 22 that is arranged below the rotary shaft 21 and is fixed to the opposite end of the rotary shaft 21 is arranged above the flange 12. As shown in FIG.
2 is sandwiched between the shutter piece 20 and the flange 22. When the flange 22 rotates, the shutter piece 20 also rotates, and the shutter piece 10 and the flange 12 also rotate.
Can be rotated independently of. The shutter piece 10 and the shutter piece 20 are set to rotate about the same central axis.

As shown in FIG. 3, each flange 12 and the drive unit 5 are connected by a link mechanism 3. The link mechanism 3 includes a plurality of links 13 pivotally attached to each flange 12, one end of the link 13 is pivotally attached to a flange fixed to the drive shaft of the drive device 5, and the drive shaft of the drive device 5 rotates. Then, the link 13 swings in its longitudinal direction to rotate each flange 12, and in conjunction with this, the shutter piece 10 also rotates to open / close the first shutter 1. Similarly, each flange 22 and the drive device 6 are connected by a link mechanism 4 as shown in FIG. 4, and the link mechanism 4 is composed of a plurality of links 23 pivotally attached to each flange 22. One end of the link 23 is pivotally attached to a flange fixed to the drive shaft of the drive device 6, and like the link mechanism 3, the rotation of the drive shaft of the drive device 6 causes the link 23 to swing in its longitudinal direction. By rotating each flange 22 to rotate the shutter piece 20, the opening / closing operation of the second shutter 2 is performed.

FIG. 7 to FIG. 13 show steps up to dividing and molding the food material continuously formed in a rod shape by the first shutter 1 and the second shutter 2. In each figure, (a) and (b) respectively show a plan view and a side view of the shutter, and the shutter piece 20 of the second shutter 2 is shaded for easy understanding. As shown in FIG. 7, the food material F extruded from the extrusion die 90 has four shutter pieces 10.
Then, the shutter pieces 10 are rotated so as to close the area surrounded by the shutter. Figure 8
Then, the rotation of each shutter piece 10 further progresses, and as shown in FIG.
As shown in (b), the strip-shaped projections 101 on the divided surface of the shutter piece 10 squeeze the food F. In FIG. 9, each shutter piece 10 is further rotated, the edges 103 of the shutter pieces 10 are brought into contact with each other, and the food material F is divided. At this time, the position of the support member 70 is controlled so that the support member 70 supports the divided food material F and the food material F is not separated from the lower surface of the shutter piece 10. The support member 70 supports the food material F until the shaping process by the second shutter 2 described below is completed. When it is further rotated, as shown in FIG. 10, each shutter piece 10 is completely closed. FIG. 14 schematically shows the surface of the food material F in this state. The divided surface of each shutter piece 10 is rotated to press and slide on the surface of the food material F to narrow it down, so that a concave portion is formed, and four convex portions indicated by A are formed at the boundary (flat surface). (Refer to FIG. 14A.) Four convex portions are gathered at the apexes to be in a pointed state (see front view 14B). Since the outer skin material is mainly made of soft flour, it is poor in elasticity and the uneven shape shown in FIG. 14 is not reduced. The curve drawn in the concave portion shows the locus on the surface of the food material on which the dividing surface of the shutter piece 10 is pressed and slid.
Is pressed and slid clockwise. Therefore, just before the division, the food F is narrowed down by the closing operation of the shutter piece 10.
As the food becomes thinner, the food F rotates clockwise, and by the time each shutter piece 10 is completely closed, the position of the convex portion on the surface of the food F is shifted from the dividing surface of the shutter piece 10 in the clockwise direction. .

Next, as shown in FIG. 11, the second shutter 2
When each of the shutter pieces 20 is rotated, the convex portion A shown in FIG. 14 is located at a position displaced from the dividing surface of the shutter piece 10 as described above, and thus the shutter piece 20 that rotates in the same manner as the shutter piece 10 rotates. The slope between the strip-shaped protrusion 201 and the lower surface slides on the surface of the divided food material F so as to intersect the convex portion. In FIG. 12, the shutter pieces 20 are further rotated so that their edge portions 203 come into contact with each other, and the convex portions shown in FIG. 14 are almost entirely slid and evened by the shutter pieces 20. When the shutter pieces 20 are further rotated to be completely closed, as shown in FIG. 13, the lower surface of each shutter piece 20 becomes substantially flat, and the tops of the divided foods F are evened out. Become. FIG. 15 schematically shows the surface of the food material F in a state where each shutter piece 20 is completely closed, and the locus of the shutter piece 20 is drawn so as to overlap with the locus of the shutter piece 10 shown in FIG. . As is clear from this figure, a curve showing the locus of the shutter piece 20 intersects with the convex portion A formed at the time of division by the closing operation of the first shutter 1 (see plan view 15 (a)). , It can be seen that the closing operation of the second shutter 2 makes the leveling uniform. In addition, at the position of the concave portion formed between the convex portions A, the convex portion B due to the closing operation of the second shutter 2
Is formed, the entire surface of the food material F is evened (see front view 15 (b)).

In the above description, the rotation operation of each shutter piece 20 of the second shutter is started with the first shutter completely closed, but the rotation of the shutter piece 20 is started before the division. It doesn't matter. That is, if the food F rotates clockwise to some extent, shaping by the second shutter becomes possible. [Second embodiment]

In the first embodiment, the rotating shafts of the first shutter 1 and the second shutter 2 are coaxial, but they may be different shafts. Therefore, as a second embodiment, an embodiment in which the rotating shafts of the first shutter 1 and the second shutter 2 are separately provided will be described. FIG. 16 shows a plan view of the shutter mechanism. Since the mechanism other than the shutter mechanism is the same as that in FIG. 1, the description thereof is omitted here.
In FIG. 16, in order to facilitate understanding, the first shutter 1
The link mechanism 3 is drawn with a solid line, and the second shutter 2 and the link mechanism 4 are drawn with a dotted line. The rotation axis of the second shutter 2 is provided between the rotation axes of the first shutter 1 as shown in FIG. 16, and each shutter piece 20 is seen in a plan view.
Are arranged between the shutter pieces 10. Figure 17
The top view of the state where the 1st shutter 1 was opened is shown. One end of a rotating shaft 110 is fixed to each shutter piece 10, and a flange 120 is fixed to the other end of the rotating shaft 110. A plurality of links 130 are pivotally attached to each flange 120 and connected to each other. ing. One end of a link 130 is pivotally attached to a flange fixed to the drive shaft of the drive device 5, and when the drive shaft rotates, the link 130 swings in the longitudinal direction to rotate each flange 120 and each shutter piece. The opening / closing operation of 10 is performed. Similarly, FIG. 18 shows a plan view of the second shutter 2 in an open state, in which the shutter piece 20 is fixed to one end of the rotating shaft 210 and the flange 220 is fixed to the other end.
A plurality of links 230 are pivotally attached to each flange 220. One end of the link 230 is pivotally attached to a flange fixed to the drive shaft of the drive device 6, and each shutter piece 20 opens and closes by the rotation of the drive shaft, as in the first shutter 1.

19 to 24 show the steps up to the split molding of the food F by the first shutter 1 and the second shutter 2. In each drawing, (a) and (b) respectively show a plan view and a side view of the shutter, and the shutter piece 20 of the second shutter is shaded for easy understanding. In FIG. 19, the food material F descends to the area surrounded by each shutter piece 10 as in the first embodiment, and the first shutter 1 starts the closing operation. In FIG. 20, each shutter piece 10 rotates, and the strip-shaped protrusions 101 squeeze the foodstuffs F. In FIG. 21, the strip-shaped protrusions 101 come into contact with each other to divide the foodstuffs F. Before the food material F is divided, the shutter piece 20 of the second shutter 2 rotates to hold the food material F as shown in FIG. By sandwiching the foodstuffs F in this way, the rotation of the foodstuffs F immediately before the division described in the first embodiment can be suppressed. Further, the supporting member 70 supports the divided food material F so as not to separate from the lower surface of the first shutter 1 as in the first embodiment. In FIG. 22, the first shutter 1 and the second shutter 2 perform the closing operation in parallel. At this time, since the shutter pieces 20 are arranged between the shutter pieces 10, the shutter pieces 20 intersect the convex portions formed on the surface of the food F by the shutter pieces 10 as shown in FIG. It will be pushed and slid as shown. FIG. 23
Then, the first shutter 1 is completely closed, the shutter piece 20 is further rotated to slide on the top of the divided food F, and in FIG. 24, the second shutter 2 is also completely closed. As a result, the lower surface becomes a substantially flat state, so that the unevenness of the surface of the divided food material F becomes even as in the case of the first embodiment. [Modification]

25 and 26 show modifications of the first and second embodiments, respectively. Both figures show plan views of the shutter mechanism, and the second shutter 2 below the first shutter 1 is shaded. In FIG. 25, the shutter piece 10 and the shutter piece 20 in the case of the first embodiment are modified in directions opposite to each other, and are rotated in directions opposite to each other. Therefore, since the shutter piece 20 slides on the food material surface in the direction opposite to the pressing sliding direction of the divided surface of the shutter piece 10, the portion pressed by the shutter piece 10 is returned to the original state so that the food material surface is further removed. It becomes possible to make uniform. Similarly, FIG. 26 shows a modification in which the shutter piece 10 and the shutter piece 20 in the second embodiment are oriented in opposite directions. Also in this case, as shown in FIG. 25, the shutter piece 20 slides on the food material surface in the direction opposite to the pressing sliding direction of the divided surface of the shutter piece 10 to make the food material surface more uniform.

Further, in the above-mentioned embodiment, the divided food material is shaped by the second shutter, but the unevenness generated on the food material surface also occurs on the surface of the food material continuously formed in a rod shape after the division. There is. That is, there are problems similar to the above-mentioned problems such that the bottom surface of the final food product has irregularities, which reduces the commercial value. Therefore, in order to solve these problems, in the above-described embodiment, the second shutter 2 is arranged above the first shutter 1,
The divided pieces of the food continuously formed in a rod shape formed by the closing operation of the first shutter 1 are slid by the shutter pieces of the second shutter to even out the unevenness of the surface. As described above, not only the above-described embodiment but also when unevenness occurs on the food material surface during division, shaping by a shutter is possible, and a smooth surface can be obtained by sliding the food material surface with a shutter piece. it can.

Although the embodiments according to the present invention have been described above, the first shutter and the second shutter use four shutter pieces in the above embodiments, but the number of shutter pieces may be plural. There is no particular limitation. Further, the number of sheets may be different between the first shutter and the second shutter.
For example, it is possible to use a shutter mechanism including six shutter pieces as shown in FIG. In this example, the rotating shafts 11 are fixed to the six shutter pieces 10, and the shutter closing operation is performed by rotating the shutter pieces 10. Of course, it is also applicable to the second shutter.
In the above embodiment, the shutter piece is opened and closed to be opened and closed, but it may be slid to be opened and closed. For example, as shown in FIG. 28, the six shutter pieces 10 can be opened and closed by reciprocating by sliding in the arrow direction. Further, as shown in FIG. 29, each shutter piece 10 is provided with an elongated guide hole, and the rotary pin 1 inserted into the guide hole.
It is also possible to open and close the shutter pieces 10 by rotating 11 to make each shutter piece 10 slide while swinging. Further, the example shown in FIGS. 30 and 31 is a case where the rotating shaft 11 continuously rotates to one side to open and close the shutter.
In FIG. 30, two divided surfaces of the shutter piece 10 are formed, and each divided surface is provided in point symmetry with the rotating shaft 11.
While the shutter is rotating once, the shutter piece 10 can be opened and closed twice. Further, in FIG. 31, only one divided surface of the shutter piece 10 is formed, and the shutter piece 10 performs one opening / closing operation while the rotating shaft 11 makes one rotation.
As described above, various drive mechanisms can be adopted for the drive mechanism of the first shutter and the second shutter, and the drive mechanism is not limited to the above-mentioned embodiment. Further, different drive mechanisms may be used for the first shutter and the second shutter. For example, the first shutter performs an opening / closing operation by sliding, and the second shutter performs an opening / closing operation by a swing-type.

[0018]

As described above, in the food product split molding method and apparatus according to the present invention, the food product continuously formed in the shape of a bar is divided into the food product divided surfaces formed by the closing operation of the first shutter. The surface of the food material can be shaped by sliding with the shutter piece of the second shutter. That is, it becomes possible to make the convex portion even by the sliding of the shutter piece of the second shutter to form a smooth surface on the flower pattern-like irregularities generated after the division by the first shutter. Further, when the food material continuously formed in a rod shape has a layered structure of an inner material and an outer skin material, the unevenness of the outer skin material of the divided food materials can be leveled to make the thickness substantially uniform. it can. Further, by devising the sliding operation of the second shutter, it becomes possible to positively change the shape of the divided food material. For example, the sliding operation of the second shutter may be performed so that a protrusion is formed at the center of the food material. Further, by operating the second shutter during the operation of the first shutter, it is possible to perform the split molding of the food in a shorter time. Further, by sandwiching the food material divided by the shutter pieces of the second shutter before the food material is divided by the first shutter, the subsequent shaping operation can be performed more stably. Since the first shutter and the second shutter can be driven by the same driving means, the driving mechanism can be simplified and the space for disposing the two shutters can be reduced, so that the device can be made compact. Become. Then, the food material is supported by the support means while the surface of the food material is shaped by the second shutter, whereby more stable shaping can be performed. Further, by shaping the divided surface of the food material continuously formed into a rod shape by the second shutter, it is possible to shape the portion that will be the bottom surface of the final food product, and the inner material and outer skin material as described above. In the case of the layered structure, it is possible to increase the thickness of the outer cover material by sliding the outer cover material with the shutter piece of the second shutter.
