Description

  The present invention relates to a roll-shaped food manufacturing apparatus for manufacturing a roll-shaped food consisting of an outer skin and a middle tool wrapped in the outer skin.

Rolled foods such as fresh spring rolls and crepes are generally manufactured by placing the inner ingredient on the outer skin, winding the inner ingredient together with the outer skin, and pressing it from the surroundings to adjust the shape. . In addition to fresh spring rolls, rolled foods include sushi rolls, California rolls, burritos, roll sands, tortillas and the like.
However, when a roll-shaped food is manufactured by hand, it takes time, and thus problems such as fatigue occur, and there is a limit to producing a large amount of roll-shaped food over a long period of time.

  In view of such a situation, the applicant of the present application has proposed a rolled sushi manufacturing apparatus for manufacturing rolled sushi in roll-shaped foods in Patent Document 1 below.

FIG. 25 is an explanatory diagram showing a process of manufacturing rolled sushi with the rolled sushi manufacturing apparatus (500) disclosed in Patent Document 1 below.
The rolled sushi manufacturing apparatus (500) has two upper rollers (501) and a lower roller (502), and has a configuration in which the outside is surrounded by an endless track (503).
As a process of manufacturing the rolled sushi with the rolled sushi manufacturing apparatus (500), first, as shown in FIG. 25 (a), on the endless track (503) between the two upper rollers (501), A pile (G51) and material (G52) corresponding to the tool are loaded.
And as shown in FIG.25 (b), the distance between two upper rollers (502) is shortened, and an endless track (503) is slackened. By rotating the roller in this state, the endless track (503) moves, and the shear (G51) and the material (G52) rotate on the endless track (503). Thereby, the shape (G51) and the material (G52) are formed in a substantially circular cross section.
After the shari (G51) and the material (G52) are formed in a substantially circular cross section, as shown in FIG. 25 (c), laver (K5) corresponding to the outer skin is inserted under the shari (G51), and the roller Rotate the seaweed (K5) to complete the rolled sushi (see FIG. 25 (d)).
By using such a rolled sushi manufacturing apparatus (500), work efficiency can be improved compared with manufacturing individually by hand.

However, in the sushi roll manufacturing apparatus (500), although the inner ingredients can be wound with the outer skin, the sushi roll cannot be tightened because it cannot be pressed from around. For this reason, a step of manually winding the rolled sushi produced by the rolled sushi production apparatus (500) is required, and the work is complicated.
In addition, it is necessary to go through a process of manually inserting seaweed (K5), which is a factor that makes the work more complicated.

Moreover, in the rolled sushi production apparatus (500), since the endless track (503) is composed of a mesh conveyor, when the roll-shaped food is wound on the endless track, a net-like mark remains on the outer skin of the manufactured roll-shaped food, Depending on the type of food, the appearance may not be preferable.
Furthermore, when small ingredients such as chopped vegetables are used as the filling, the filling will fall from the mesh of the endless track, so for example, it has not been possible to produce tortillas in which chopped vegetables are wrapped with a thin dough of flour. .
In addition, since the upper rollers (501) having ridges at both ends are used, the outer peripheral surfaces of the two upper rollers (501) cannot be brought into close contact with each other. There was a case where the inside spilled out.

  Also, for example, when producing fresh spring rolls, rice paper is used for the outer skin of fresh spring rolls, but when trying to produce fresh spring rolls by applying the above-mentioned roll sushi production device, the rice paper is pre-soaked in warm water, etc. It was necessary to add moisture.

Embodiments of a roll-shaped food production apparatus according to the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram showing the overall configuration of a roll-shaped food production apparatus (100) according to the first embodiment of the present invention.
First, the structure of the roll-shaped foodstuff manufacturing apparatus (100) which concerns on a 1st Example is demonstrated, referring FIG.

  The rolled food manufacturing apparatus (100) according to the present invention includes a first upper roller (1), a second upper roller (2), a third upper roller (3), a lower roller (4), and these rollers (1). ) To (4) have an endless track (5) suspended over the outer periphery. Furthermore, it also has an opening / closing mechanism (6), a weight roller (7), a pressing mechanism (8), and a water tank (9), which will be described in detail later.

The first upper roller (1), the second upper roller (2), and the third upper roller (3) are disposed at substantially the same height and substantially in parallel.
The lower roller (4) is disposed below a substantially intermediate position between the first upper roller (1) and the second upper roller (2).

The upper surface of the endless track (5) located between the first upper roller (1) and the second upper roller (2) serves as an intermediate component placement portion (A) on which the intermediate component of the roll-shaped food is placed. Moreover, the upper surface of the endless track (5) located between the second upper roller (2) and the third upper roller (3) serves as a skin placing portion (B) on which the skin of the roll-shaped food is placed.
The roll-shaped food manufacturing apparatus (100) manufactures a roll-shaped food by using a middle tool placed on the middle tool placing portion (A) and a skin placed on the outer skin placing portion (B). Can do.
Examples of the roll food produced by the roll food production apparatus (100) include fresh spring rolls, crepes, roll sandwiches, burritos, and sushi rolls, but are not limited thereto.

Both ends of the second upper roller (2) and the third upper roller (3) are connected to each other by a connecting rod (21). As a result, when the second upper roller (2) is moved by the opening / closing mechanism (6) as will be described later, the third upper roller (3) does not change the height and is at the substantially same height position. The two upper rollers (2) move while maintaining a constant distance.
As described above, the third upper roller (3) moves while maintaining the substantially same height position, so that the outer skin placed on the outer skin placing portion (B) is prevented from slipping down.
The process for producing the roll food will be described in detail later.

  The endless track (5) is stretched around the outer periphery of the first upper roller (1), the second upper roller (2), the third upper roller (3), and the lower roller (4). Then, when the lower roller (4) is rotated by driving a motor (not shown), the endless track (5) is rotated together with other rollers, and the inner tool and the outer skin on the endless track (5) are moved.

In FIG. 1, a net-like wire conveyor is shown as the endless track (5) (however, the mesh is drawn only on the upper surface), but the type of endless track is not limited to this, and the inner tool and the outer shell are attached. Anything that can be placed is acceptable.
For example, a configuration using a sheet-like endless conveyor having a flat outer peripheral surface (surface on which the inner tool or outer skin is placed) can be preferably employed. As the sheet-like conveyor, a belt conveyor made of synthetic resin or rubber can be used.
In the present invention, as will be described in detail in the process of producing a rolled food product later, the rolled food product is wound by being pushed from around by the endless track (5), but the surface of the endless track (5) is flat. If it is not (for example, in the case of a net shape as shown in FIG. 1), the rolled food is wound around the endless track (5), so that the trace of the endless track (5) remains on the rolled food. However, when the outer peripheral side surface of the endless track (5) is flat, it is possible to prevent the endless track (5) from remaining on the roll-shaped food, and it is possible to create a roll-shaped food with a good appearance. . Moreover, even when the inside tool is small, such as chopped vegetables, it can be placed on the conveyor without being dropped.

In the present invention, as shown in FIG. 2, it is most preferable to use a two-layered conveyor in which a sheet-like conveyor (52) having a flat outer peripheral surface is superimposed on the surface of a net-like conveyor (51) such as a wire conveyor. preferable.
The mesh conveyor (51) is an endless conveyor formed by combining metal wires such as stainless steel wires in a ladder shape.
The sheet-like conveyor (52) is a conveyor formed with an endless sheet having a flat surface. The material is not particularly limited as long as it has flexibility, but tetrafluoroethylene resin is particularly preferably used. This is because food materials can be prevented from adhering to the conveyor surface. In addition, when using tetrafluoroethylene resin, the sheet itself forming the conveyor may be formed from tetrafluoroethylene resin, or the sheet forming the conveyor is formed from other materials and the surface thereof is tetrafluorinated. You may coat by ethylene resin.

  The opening / closing mechanism (6) makes the first upper roller (1) and the second upper roller (2) approach and separate from each other. Hereinafter, the opening / closing mechanism (6) will be described. In the following description, FIG. 3 is also used as appropriate.

The opening / closing mechanism (6) has two rotating shafts (621) and (622) connected to the first upper roller (1) and the second upper roller (2) by a connecting rod (61). .
The connecting rod (61) has an upper end connected to both ends of the first upper roller (1) and the second upper roller (2), and a lower end connected to the two rotating shafts (621) and (622), respectively. It is connected.
Although not shown, both ends of the rotating shaft of the lower roller (4) and the two rotating shafts (621), (622) are rotated to an inverted triangular plate so that the positional relationship does not change. It is fixed freely.

A cylindrical collar (623) having a diameter larger than those of the rotary shafts is fitted on the rotary shafts (621) and (622). These collars (623) do not rotate integrally with the rotating shafts (621) and (622), but act as support rollers that rotate with the movement of the endless track by contacting the inner surface of the endless track (5). Can be made. In addition, gears (631) and (632) that mesh with each other are attached to one end portions of the rotation shafts (621) and (622), respectively, and an operation rod ( 64) is connected.
By pushing down the operating rod (64), one rotating shaft (622) connected to the operating rod (64) rotates counterclockwise, and the gear (632) also rotates counterclockwise. . Then, the gear (631) meshing with the gear (632) rotates clockwise, and the other rotation shaft (621) rotates clockwise accordingly.
When the two rotating shafts (621) and (622) rotate inward from each other, the upper ends of the left and right connecting rods (61) move inwardly (in the closing direction), and the left and right connecting rods (61) and The first upper roller (1) and the second upper roller (2) connected to each other move in directions approaching each other. At this time, since the third upper roller (3) is connected to the second upper roller (2) by the connecting rod (21), the second upper roller (2) moves to move the third upper roller (2). 3) also moves in the horizontal direction while maintaining a constant distance from the second upper roller (2).

  The operation (64) may be operated (pressed down) by connecting a foot pedal (not shown) to the operation unit (64) and stepping on the foot pedal. It can also be automated by programming to link with the movement of the endless track (5).

  In the roll-shaped food manufacturing apparatus (100), the endless track (5) rotates along each roller when the first upper roller (1) and the second upper roller (2) approach by the opening / closing mechanism. Designed.

The weight roller (7) is disposed at an intermediate position between the first upper roller (1) and the second upper roller (2) and above the endless track (5). Further, as shown in FIG. 1, the weight roller (7) is composed of two disk-like rollers connected to each other by a connecting rod (71) fixed to the outer position of the first upper roller (1). The two disc-shaped rollers are respectively placed on both end portions in the width direction of the endless track (5).
The weight roller (7) lowers the endless track (5) by its own weight when the first upper roller (1) and the second upper roller (2) are moved toward each other by the opening / closing mechanism (6). It plays a role.
FIG. 3 shows a state in which the first upper roller (1) and the second upper roller (2) are approaching. When the first upper roller (1) and the second upper roller (2) approach, the endless track (5) between the first upper roller (1) and the second upper roller (2) is tensioned (pulled left and right). Therefore, the endless track (5) between the first upper roller (1) and the second upper roller (2) is lowered by the weight of the weight roller (7).
Since the weight roller (7) rotates around the connecting rod (71) when lowered, as shown in FIG. 3, the weight roller (7) is positioned closer to the first upper roller (1) side as shown in FIG.

As shown in FIGS. 1 and 3, a pressing mechanism (8) is provided at an outer position of the endless track (5).
When the first upper roller (1) and the second upper roller (2) are approaching, the pressing mechanism (8) is positioned below the two upper rollers (1) and (2) and the lower roller It plays a role of pressing the endless track (5) from the outside in the upper position of (4).
When the first upper roller (1) and the second upper roller (2) are close to each other, the endless track (5) is lowered by the weight roller (7), but is pressed by the pressing mechanism (8). Thus, the lowered endless track (5) can be raised. Thereby, since roll-shaped food will be pushed from the circumference by the 1st upper roller (1), the 2nd upper roller (2), and endless track (5), it can wind up tightly. In detail, it demonstrates in the process of manufacturing a roll-shaped foodstuff later.

The pressing mechanism (8) includes a pressing roller (82) that presses the endless track (5), a rotating shaft (81) that rotates around the central axis, both ends of the rotating shaft (81), and both ends of the pressing roller (82). It consists of the arm which connects each part.
Then, by rotating the rotating shaft (81), the pressing roller (82) can be rotated about the rotating shaft (81) to press the endless track (5). By having such a structure, the rotational force of the rotating shaft (81) is effectively transmitted to the pressing roller (82). Therefore, the endless track (5) can be pressed to apply tension to the track, and the lowered endless track (5) can be reliably raised.
The axial length of the pressing roller (82) is set shorter than the axial length of the first upper roller (1).

The skin humidifier (9) is a water tank and contains water or warm water. The outer humidifier (9) is used to soften rice paper or the like, which is a hard outer shell, by immersing it in water, for example, when producing fresh spring rolls.
In fresh spring rolls, rice paper is used as the outer skin. However, since the rice paper is hard as it is, it is necessary to immerse it in water or warm water in order to wind the inside without breaking. Therefore, by setting it as the apparatus which has an outer skin humidifier (9), rice paper (outer skin) can be easily immersed in water and a fresh spring roll can be manufactured efficiently.
The position where the outer humidifier (9) is installed is preferably near the operation rod (64). The operator operates the opening / closing mechanism (6) with the operation rod (64). However, since the skin humidifier (9) is close to the operation rod (64), the skin is removed from the skin humidifier (9) (water tank). This is because the work soaked in water and the work of operating the operation mechanism (6) can be performed at the same position, and the work efficiency is improved.
However, the position, size, and type of the skin humidifier (9) are not particularly limited, and may be designed for the convenience of the operator such as the installation space. For example, a steam humidifier or the like can be used as in the second embodiment described later.
What is humidified by the outer humidifier (9) is not limited to rice paper, and is not particularly limited as long as it is an outer skin that requires moisture for softening. The water to be put into the water tank is arbitrary such as warm water, cold water, room temperature water, etc., and may be moisture such as steam as in the second embodiment described later.

Then, the process of manufacturing roll-shaped food using a roll-shaped food manufacturing apparatus (100) is demonstrated.
First, as shown in FIG. 4, the middle tool (G) is placed on the middle tool placing portion (A) between the first upper roller (1) and the second upper roller (2), and the second upper roller (2 ) And the third upper roller (3), the outer skin (K) is placed on the outer skin placing portion (B).
At this time, when using rice paper or the like as the outer skin (K), the rice paper may be used after being humidified by the outer skin humidifier.
Of course, an outer skin such as rice paper may be first placed on the middle tool placement portion (A), and then the middle tool may be placed thereon and wound together with the outer skin and the middle tool.
However, placing the outer skin such as rice paper on the outer skin placement part (B), pulling the outer skin when winding the inner tool, and winding it at the same time ensures that the inner tool can be wound with the outer skin. preferable.

Next, as shown in FIG. 5, the first upper roller (1) and the second upper roller (2) are brought close to each other, and the weight of the weight roller ((7) in FIG. 1) is reduced by the weight of the first upper roller (1) and The endless track (5) spanned between the second upper rollers (2) is lowered.
By lowering the endless track (5) spanned between the first upper roller (1) and the second upper roller (2), the middle tool (G) is surrounded by the endless track (5). It exists in the range (C) (see FIG. 5).
At this time, as described above, the weight roller (7) rotates around the connecting rod (71), so that the descending portion of the endless track (5) is located closer to the first upper roller (1) as shown in the figure. It is in.

  The first upper roller (1) and the second upper roller (2) are approached by an opening / closing mechanism ((6) in FIG. 1). Specifically, the operation is performed by the operator depressing the operation rod (64).

After the endless track (5) is lowered by the dead weight of the weight roller ((7) in FIG. 1) or substantially simultaneously, the endless track (5) is pushed from the outside by the pressing mechanism (8) as shown in FIG. Thereby, the endless track (5) is pulled, and the position of the middle tool (G) is raised.
When the first upper roller (1) and the second upper roller (2) are close to each other, the middle tool (G) is moved by the endless track (5), the first upper roller (1), and the second upper roller (2). Although it is in an enclosed state, the position of the middle tool (G) is raised at this time, so that the middle tool (G) is moved to the endless track (5), the first upper roller (1), and the second upper roller (2 ) Is pressed from around and tightened. Further, when the position of the middle tool (G) rises, the endless track (5) is pulled up from the first upper roller (1) side and rises. Therefore, it is formed into a roll while being tightly wound from the periphery.

Thereafter, as the endless track (5) moves, the outer skin (K) moves and is caught between the first upper roller (1) and the second upper roller (2) as shown in FIG. Wound on the outer periphery of (G). Even in this process, since the pressing mechanism (8) pushes the endless track (5), the outer shell (K) is wound around the inner tool (G) while being pressed from around, and the roll is tightly wound. Food.
In addition, since the position of the middle tool (G) is raised, the outer skin (K) smoothly enters under the middle tool and prevents the outer skin (K) from entering between the middle tools (G). (See FIG. 7).

  Drawing 8 is a figure showing the state where roll-shaped food was completed by continuing the movement of endless track (5) further. As shown in FIG. 8, after the rolled food is completed, the operating rod (64) is pushed up to separate the first upper roller (1) and the second upper roller (2), and the first upper roller (1). The finished roll-shaped food can be easily taken out by raising the endless track (5) stretched between the second upper rollers (2) again.

Fig.9 (a) is the figure which showed the completed roll-shaped foodstuff (raw spring roll), and FIG.9 (b) is the figure which showed what cut | disconnected the roll-shaped foodstuff (fresh spring roll) in substantially half.
By using the roll-shaped food production apparatus (100), as shown in FIG. 9, the roll-shaped food (raw spring roll) in which the inner ingredient (G) is wrapped in the outer skin (K) and tightly wound is produced. Can do.
Moreover, even when the roll-shaped food is tightly wound, by using the endless track (5) having a flat outer peripheral surface, it is possible to prevent the endless track (5) from being left on the roll-shaped food. It is possible to produce a roll-shaped food product having a good appearance.

Next, a second embodiment of the present invention will be described.
FIG. 10 is an explanatory view showing a roll-shaped food production apparatus (200) according to the second embodiment.
The roll-shaped food manufacturing apparatus (200) is different from the roll-shaped food manufacturing apparatus (100) according to the first embodiment in the skin humidifier. For convenience, the skin humidifier of the roll food manufacturing apparatus (200) is referred to as a skin humidifier (91). The roll food manufacturing apparatus (200) is also provided with an automatic feeder (10).

The skin humidifier (91) generates steam and exposes the skin placed on the skin placing part to the steam.
For example, when making fresh spring rolls, rice paper is used as the outer skin (K), but by having the outer skin humidifier (91), rice paper (outer skin (K) before being placed on the outer skin placing portion (B) is used. ) Is not necessary to be pretreated, and the number of steps can be reduced.
In addition, what is necessary is just to operate an opening-closing mechanism ((6) in FIG. 1), after exposing rice paper (outer skin (K)) to vapor | steam by the outer skin humidifier (91).

Examples of the skin humidifier (91) include a steam type in which water is boiled to generate steam, an ultrasonic type in which water is finely particulated and blown out as it is, and a vaporization type in which water is evaporated by sending wind. Can do. In addition, a hybrid system in which air is supplied by adding water with a heater or the like and soaking water after raising the temperature into a filter or the like can also be mentioned. The hybrid type is preferable because it can have a high humidification ability. However, the skin humidifier (91) is not limited to these.
Furthermore, in FIG. 10, the outer skin humidifier (91) is provided on the upper part of the endless track (5) and the steam is applied to the outer skin (K) from above, but it may be provided so as to apply the steam from the bottom or side. Good.
Further, the outer skin (K) is not limited to rice paper, and is not limited as long as it is necessary to apply steam.

The automatic feeder (10) is for automatically supplying the outer skin to the outer skin placing portion.
When an automatic feeder is provided, further automation of the production of roll food can be achieved by operating the skin humidifier (91) and the opening / closing mechanism ((6) in FIG. 1) in conjunction with the supply of the skin by the automatic feeder. Can be achieved, and the working efficiency is further improved.
As the automatic feeder (10), for example, a structure in which a plurality of outer skins (K) are stacked and extruded one by one from the bottom can be used. Further, since the outer skin (K) is dry before being placed on the outer skin placing portion (B), the individual outer skins do not stick to each other and can be easily supplied one by one.

Next, a third embodiment of the present invention will be described.
FIG. 11 is a schematic view showing a rolled food manufacturing apparatus (300) according to the third embodiment.
The roll food manufacturing apparatus (300) employs a structure that does not have the third upper roller in the apparatuses of the first and second embodiments, and other configurations are omitted, but the first is omitted. And it is the same as that of 2nd embodiment.
Specifically, an endless track (5) is wound around the outer periphery of the first upper roller (1), the second upper roller (2), and the lower roller (4). Since there is no third upper roller, the entire apparatus is compact and can be installed even if the installation space is small.

When the roll food is produced by the roll food production apparatus (300), the first upper roller (1) and the second upper roller (2) are brought close to each other by the opening / closing mechanism as in the first embodiment, and the pressing mechanism. By pressing according to (8), a rolled food is produced.
However, since there is no outer skin mounting portion, as shown in FIG. 12, when the first upper roller (1) and the second upper roller (2) are approaching, the outer skin (G) K) will be inserted by hand.

Finally, a fourth embodiment of the present invention will be described.
FIG. 13 is a schematic diagram showing an overall configuration of a roll-shaped food manufacturing apparatus (400) according to the fourth embodiment.
Hereinafter, the difference between the roll-shaped food production apparatus (400) and the roll-shaped food production apparatus (100) of the first embodiment described above will be described, and the same components as those in the roll-shaped food production apparatus (100) are denoted by the same reference numerals. Therefore, the description is omitted.

  The roll-shaped food manufacturing apparatus (400) does not have the third upper roller, and the endless track (5) has the first upper roller (1), the second upper roller (2), and the lower roller (4). It is stretched around the periphery.

  The endless track (5) has a two-layer structure of a mesh conveyor (51) constituting an inner endless track and a sheet conveyor (52) constituting an outer endless track. In FIG. 13, in order to make the drawing easier to see, a part of the parallel lines representing the mesh of the mesh conveyor (51) is omitted on the left side of the endless track (5).

The mesh conveyor (51) is an endless conveyor formed by combining metal wires such as stainless steel wires in a ladder shape. The mesh conveyor (51) is surely rotated without slipping with the rotation of the lower roller (4) by the mesh meshing with the teeth of the lower roller (4) having teeth on the outer peripheral surface.
The mesh conveyor (51) and the sheet conveyor (52) may be simply overlapped without being bonded, or may be bonded and integrated. Even when the two belts are simply stacked without being bonded, the two belts can be rotated together by sufficiently stretching the two conveyors and passing them over the rollers.

  The sheet-like conveyor (52) is a conveyor formed with an endless sheet having a flat surface. The material is not particularly limited as long as it has flexibility, and can be appropriately selected from synthetic resin, cloth, rubber, and the like, but tetrafluoroethylene resin is particularly preferably used. This is because food materials can be prevented from adhering to the conveyor surface. In addition, when using tetrafluoroethylene resin, the sheet itself forming the conveyor may be formed from tetrafluoroethylene resin, or the sheet forming the conveyor is formed from other materials and the surface thereof is tetrafluorinated. You may coat by ethylene resin.

As described above, the endless track (5) has a two-layer structure of the mesh conveyor (51) constituting the inner endless track and the sheet conveyor (52) constituting the outer endless track. Is as follows.
First, in the case of only the mesh conveyor (51), when a small middle tool such as chopped vegetables is placed on top of the endless track (5), the middle tool falls from the gap (mesh) of the conveyor. Falling is prevented by the sheet-like conveyor (52) on the outside.
In addition, in the case of only the sheet-like conveyor (52), the strength of the endless track (5) may be lowered, resulting in a problem in durability. However, the two-layer structure improves the strength and makes it durable. Excellent in properties. And since strength is excellent, it becomes possible to clamp | tighten a roll-shaped foodstuff firmly, and can produce the roll-shaped foodstuff which does not produce the shape-molding firmly formed. Further, when winding the roll-shaped food, the endless track is prevented from being bent between the two weight rollers (7), and a beautiful cylindrical roll-shaped food can be obtained.

FIG. 14: is a figure which shows the structure of the opening / closing mechanism (6) of a roll-shaped foodstuff manufacturing apparatus (400).
The open / close mechanism (6) of the roll food manufacturing apparatus (400) is different from the apparatus of the first embodiment in the configuration of the operation mechanism for rotating the gears (631) and (632).
Specifically, the operating mechanism in the device (100) of the first embodiment is configured by the operating rod (64), but the operating mechanism in the device (400) of the fourth embodiment is configured as described below. Has been.

The operation mechanism of the device (400) of the fourth embodiment includes an operation plate (41) connected to one rotation shaft (621) so as to extend in the radial direction of the rotation shaft, and the operation plate (41). Is composed of an operating rod (42) penetrating in the vertical direction and a vertical movement means for moving the operating rod (42) up and down.
The vertical movement means includes a motor (43) and a rotating plate (44) having a rotating shaft of the motor (43) connected to the center and a lower end portion of the operating rod (42) connected to an eccentric position. ing.

A male screw is formed in the upper part of the operation rod (42), and two upper and lower springs (45) and (46) are inserted so as to cover the male screw part.
The upper spring (45) has an upper end in contact with the lower surface of the nut screwed into the male screw, and a lower end in contact with the upper surface of the operation plate (41). The lower spring (46) has an upper end in contact with the lower surface of the operation plate (41) and a lower end in contact with the upper surface of the nut screwed into the male screw.

The operation plate (41) has one end connected to one rotating shaft (621) and the other end being a free end. An upper stopper (47) and a lower stopper (48) are arranged at an upper position and a lower position of the other end portion with a predetermined distance from the upper and lower surfaces of the operation plate (41). In the illustrated example, the upper stopper and the lower stopper are integrated in a U-shape.
The upper stopper (47) prevents the other end of the operation plate (41) from rising up to a predetermined height, and the lower stopper (48) lowers the other end of the operation plate (41) to a predetermined height or less. Play a role to prevent.

The operation of the operation mechanism having the above configuration will be described below.
When the rotating shaft of the motor (43) rotates in one direction, the rotating plate (44) also rotates in the same direction (see arrow).
When the rotating plate (44) rotates, the lower end portion of the operating rod (42) attached to the eccentric position of the rotating plate (44) moves up and down accordingly. For example, in the illustrated example, when the rotating plate (44) is rotated halfway clockwise, the lower end of the operating rod (42) is moved upward, so that the operating rod (42) is lifted (see arrow) and further rotated half a turn. Then, the operating rod (42) is lowered.

When the operating rod (42) is raised, the other end of the operating plate (41) is raised, and accordingly, the gear (631) is rotated clockwise and the gear (632) is rotated counterclockwise. That is, the two gears rotate inward from each other.
Then, the rotating shaft (621) connected to the gear (631) and the rotating shaft (621) (622) connected to the gear (632) also rotate inwardly, whereby the left and right connecting rods (61) are rotated. The upper end portion rotates in the closing direction, and the first upper roller (1) and the second upper roller (2) move in directions approaching each other.

Then, when the rotating plate (44) further rotates halfway, the operating rod (42) is lowered, so that the other end of the operating plate (41) is lowered and the gear (631) rotates counterclockwise. Then, the gear (632) rotates clockwise. That is, the two gears rotate outward from each other.
Then, the rotating shaft (621) and the rotating shaft (622) also rotate outwardly, whereby the left and right connecting rods (61) rotate in the direction in which the upper ends open, and the first upper roller (1) and the first The two upper rollers (2) move in directions away from each other.

  Thus, according to the operation mechanism with which the opening / closing mechanism (6) of the roll-shaped food manufacturing apparatus (400) is provided, the first upper roller (1) and the second upper roller (2) with the rotation of the motor (43). ) Repeats proximity and separation, so there is no need to operate by hand as in the first embodiment.

Here, since the upper spring (45) and the lower spring (46) are attached so as to sandwich the operation plate (41) from above and below, the rotation shaft of the motor (43) is rotated by the rotation of the gear (631). Instead of directly interlocking with the actuator, it is interlocked via the expansion and contraction of the spring. Therefore, the left and right connecting rods (61) do not open and close rapidly, and the food material is prevented from being crushed or popped out.
Further, by providing the upper stopper (47) and the lower stopper (48), the degree of opening / closing (angular stroke) of the left and right connecting rods (61) can be defined.

In the roll-shaped food manufacturing apparatus (400), the first upper roller (1) and the second upper roller (2) are cylindrical cylinders having a cylindrical shape having no collar.
The diameters of the first upper roller (1) and the second upper roller (2) are larger than the width of the upper end portion of the connecting rod (61).
As a result, the outer peripheral surfaces of the first upper roller (1) and the second upper roller (2) can be brought into close contact with each other. Therefore, in the roll-shaped food manufacturing process described later, the two upper rollers (1) ( When the 2) is brought close to each other, it is possible to prevent the middle tool from spilling from between the two rollers.

FIG. 15 is a diagram showing the configuration of the pressing mechanism (8) of the roll food manufacturing apparatus (400). The configuration of the pressing mechanism (8) is a configuration common to all examples, and only the configuration not described in the first embodiment will be supplementarily described here.
A sprocket (83) is attached to one end of the rotating shaft (81) of the pressing mechanism (8), and the sprocket (83) is connected to a sprocket (86) attached to the rotating shaft of the motor (85). In this way, an endless chain (84) is suspended.
As a result, when the motor (85) rotates in the clockwise direction, the rotating shaft (81) also rotates in the clockwise direction, the pressing roller (82) moves toward the endless track (5), and the endless track (5). Press from the side.
When the drive of the motor (85) is stopped (the power is turned off), the force that presses the endless track (5) does not act, so the pressing roller (82) is a repulsive force that the endless track (5) tries to restore. The endless track (5) that has been deformed by being pressed by the pressing roller (82) returns to its original shape.

16 and 17 are schematic views for explaining a second opening / closing mechanism provided in the roll-shaped food production apparatus (400), and FIG. 16 is a diagram showing a state before the second opening / closing mechanism is operated, FIG. 17 is a diagram illustrating a state in which the second opening / closing mechanism is operated.
The second opening / closing mechanism includes a first upper roller (1) and a second upper roller (2) in a state where the first upper roller (1) and the second upper roller (2) are close to each other by the operation of the opening / closing mechanism (6). ) Are slightly separated from each other (about 50 mm).

The second opening / closing mechanism moves up and down by operating the contact member (11) whose one end is in contact with the inner surface of one or both of the left and right connecting rods (61) and the foot pedal (12) connected to the lower end. A vertically moving member (13) that moves; a lever member (14) having one end connected to the other end of the abutting member (11) and the other end connected to the upper end of the vertically moving member (13); It is composed of
As shown in the drawing, the contact member (11) is a member bent in a substantially L shape when viewed from the front, and the bent portion (111) is rotatable but fixed in a non-movable position.

  The lever member (14) is configured such that one end and the other end are alternately raised and lowered like a seesaw with a point between one end and the other end as a fixed fulcrum (15). And the upper end part of the spring (16) is connected to the position between the fulcrum (15) and one end part, and it always urges | biass in the direction (arrow direction of FIG. 16) which one end part falls by this spring (16). Has been.

Hereinafter, the operation of the second opening / closing mechanism will be described.
In the state shown in FIG. 16, that is, in the state where the foot pedal (12) is not pushed down, one end of the lever member (14) is urged by the spring (16) in the downward direction. 11) is subjected to a force that rotates counterclockwise around the bent portion (111). In this state, one end of the contact member (11) presses the inner surface of the left connecting rod (61), but the force is small only by the biasing force of the spring (16). The rod (61) does not move, and the first upper roller (1) and the second upper roller (2) are in close proximity (close contact) to each other.

As shown in FIG. 17, when the foot pedal (12) is stepped on and pushed down, the vertical movement member (13) is lowered, and accordingly, the other end portion of the lever member (14) is lowered and one end portion thereof is lowered. To rise. Then, since the contact member (11) rotates clockwise around the bent portion (111), one end portion of the contact member (11) faces the inner surface of the right connecting rod (61) outward (rightward). ) Since the pressing force acting at this time is larger than the urging force of the spring (16), the connecting rod (61) moves and the first upper roller (1) and the second upper roller (2) are separated from each other.
At this time, both the left and right connecting rods (61) move outward because the gears (631) and (632) are engaged. Since the rotation of the gear (631) at this time is slight, the vertical displacement is absorbed by the contraction of the upper spring (45), and the rotating plate (44) of the opening / closing mechanism (6) does not rotate. .
When the foot pedal (12) is pushed down, a limit switch (not shown) is activated to stop the motor rotating the lower roller (4), thereby stopping the movement of the endless track (5). When the push-down is released, the limit switch is released and the endless track (5) moves.

Hereinafter, the process of manufacturing roll food using the roll food manufacturing apparatus (400) will be described.
First, as shown in FIG. 18, in a state where the first upper roller (1) and the second upper roller (2) are separated from each other, the medium ingredients (G) such as chopped vegetables are placed on the first upper roller (1) and the second upper roller (1). It is placed on the upper surface of the endless track (5) that is stretched between the upper rollers (2). In addition, although the weight roller (7) is abbreviate | omitted in the figure, a middle tool (G) is mounted between a pair of weight rollers.
The left and right collars (623) are in contact with the inner surface of the endless track (5) and apply tension outward. Although not shown, in the first to third embodiments, tension can be similarly applied by a collar.

Next, as shown in FIG. 19, when the opening / closing mechanism (6) is operated to bring the first upper roller (1) and the second upper roller (2) closer to each other, the first upper roller (1) and the first upper roller (1) The endless track (5) between the two upper rollers (2) is lowered together with the middle tool (G) by the weight of the weight roller (not shown).
Subsequent to or simultaneously with the pressing roller (82) of the pressing mechanism (8), the endless track (5) of the portion located between the first upper roller (1) and the second upper roller (2) is moved from the outside. Press.

When the first upper roller (1) and the second upper roller (2) come closer, as shown in FIG. 20, the outer peripheral surfaces of the first upper roller (1) and the second upper roller (2) are endlessly tracked. Contact via (5).
Then, when the endless track (5) is further pressed by the pressing roller (32), the endless track (5) between the first upper roller (1) and the second upper roller (2) rises, thereby The middle tool (G) is tightened from around and tightened. During this ascent, the endless track (5) between the first upper roller (1) and the second upper roller (2) is pulled upward from the first upper roller (1) side. Therefore, the middle tool (G) is tightly wound from the surroundings as it rises.

In this state, the lower roller (4) is driven to rotate the endless track (5) (see the broken line arrow), so that the lower endless portion between the first upper roller (1) and the second upper roller (2) is reached. In the space surrounded by the track (5), the inner tool (G) is further tightly wound and firmly formed into a cylindrical shape.
At this time, since the outer peripheral surfaces of the first upper roller (1) and the second upper roller (2) are in close contact with each other, the middle tool (G) is not spilled.

Subsequently, as shown in FIG. 21, the foot pedal (12) is pushed down to operate the second opening / closing mechanism, thereby stopping the endless track (5), and the first upper roller (1) and the second upper roller. The outer skin (K) is inserted by hand through the gap formed between (2).
Thereafter, by releasing the depression of the foot pedal (12), the first upper roller (1) and the second upper roller (2) are brought into contact with each other, and the rotation of the endless track (5) is resumed. Then, the outer skin (K) is wound around the middle tool (G) which is drawn between the first upper roller (1) and the second upper roller (2) and formed into a cylindrical shape (see FIG. 22). Further, as the endless track (5) rotates, the inner tool (G) is completely wrapped by the outer skin (K) (see FIG. 23).

Thereafter, when the upper roller (1) and the second upper roller (2) are separated by the action of the opening / closing mechanism (6), an endless track (between the upper roller (1) and the second upper roller (2)) Since 5) rises, the finished roll food can be taken out.
FIG. 24 is a diagram showing a state in which a finished roll-shaped food is cut in half, and a tortilla wrapped with a thin dough hull (K) made of corn or wheat flour is made of a medium ingredient (G) made of chopped vegetables or the like. It is shown. If the medium ingredients such as chopped vegetables are not tightly wound, they will spill out from the cut surface. However, according to the apparatus of the present invention, the winding is sufficiently performed, and this can be prevented.

  As described above, according to the apparatus according to the present invention, various types of roll-shaped foods in a form in which the inner ingredient is wrapped with an outer skin can be efficiently produced. It is also possible to use a synthetic resin film as the outer skin and to produce a roll-shaped food in which food is wrapped with the synthetic resin film.
