Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a takoyaki machine and a takoyaki plate used therein.

[0002]

2. Description of the Related Art As shown in FIG. 1, a conventional takoyaki machine generally includes a takoyaki plate 7 having a plurality of grilled holes 8 formed in a substrate 9, and a takoyaki plate arranged below the takoyaki plate 7. And heating means (for example, a gas burner) 10 for heating the plate 7. As shown in FIG. 2, takoyaki dough (a substance obtained by dissolving flour with water or the like) 11 is poured into a grilling hole 8, which is a hemispherical recess, so that the dough slightly overflows. Then chopped boiled octopus, dried shrimp, green onions,
Add ingredients such as red ginger. Thereafter, when the dough hardens a little, the overflowing dough is gathered by the illustrated skewer member 12 so as to be raised into the grill hole 8, and the whole dough is appropriately lifted from the grill hole 8 and turned over. In this manner, the dough 11 containing the ingredients is baked in a round shape.

A conventional takoyaki plate 7 is generally cast of iron. Such a takoyaki plate 7 made of a casting has a low thermal conductivity and must be sufficiently heated by the heating means 10 before the dough 11 is poured into the takoyaki plate.
Further, in a use method in which only half of the takoyaki plate 7 is used and the other half is allowed to be used without being used, it prevents delicious baking. It is also difficult to put the takoyaki on the takoyaki plate 7 while keeping it warm, which makes it difficult to burn.

A takoyaki plate 7 made of copper is a partial improvement of the above. In this method, a pit 8 is formed by sheet metal working from a copper plate, not by casting. Since the takoyaki plate 7 made of copper has a good thermal conductivity, after the heating means 10 is operated, even if the whole plate 7 does not become hot, even if the takoyaki is started, it can be baked sufficiently deliciously. Alternatively, only half of the plate 7 can be used for baking and the other half can be used for keeping warm. However, the takoyaki plate 7 made of copper is expensive and has a high thermal conductivity, so that it has a large energy dissipation rate, low thermal efficiency, and cannot form the grilled hole 8 deeply. Conventionally, a plurality of pits are punched out of a single copper plate by sheet metal processing. However, it is not easy to punch deep holes with this sheet metal processing technique.

FIG. 3 schematically shows a conventional vibratory takoyaki machine. This is a labor-saving structure in which the dough 11 in the grill hole is rotated and baked, and the vibration frame 4 is supported on the machine frame 6 by four springs 5 so that it can vibrate, and the takoyaki plate 7 is horizontally or diagonally mounted on the vibration frame 4. At the same time, the vibration generating means 13 is attached to the vibration frame 4 and the vibration frame 4 is basically vibrated on a horizontal plane. Thus, the dough 11 in the grilled hole 8 of the plate 7 that vibrates together with the vibration frame 4 is caused to rotate.

The conventional vibratory takoyaki machine has a structure in which the vibrating frame 4 supported by a plurality of springs 5 vibrates in the horizontal direction together with the takoyaki plate 7, so that the takoyaki plate slightly swings up and down by the spring support. In such vibrations, even if the takoyaki plate is placed diagonally, the rotation function of the dough in the grilled hole will not be fully exhibited, and the takoyaki baking and taste will vary. There was a problem that it would occur.

To solve this problem, an oscillating takoyaki machine shown in FIG. 4 has been developed (Japanese Patent Laid-Open No. 2000-14311).
issue). In the drawing, 4 is a swing frame, 7 is a takoyaki plate, 10 is a heating means carried on the swing frame 4, 3 is a horizontal shaft which supports the swing frame 4 so as to be swingable, and 31 is a rotary drive by a motor. Reference numeral 6 denotes a swing-type takoyaki machine frame. When the crank 31 is rotationally driven by a motor,
The swing frame 4 swings about the horizontal axis 3. Due to this swinging motion, the dough in the grill hole 8 rotates.

[0008] Even with this oscillating takoyaki machine, there is still variation in the baking of the takoyaki. This is because if the takoyaki plate 7 is arranged in the central area just above the horizontal shaft 3, the dough in the toasting hole 8 will not exhibit a sufficient rotation function. The rotation function increases as the distance from both ends of the swing frame 4 increases.

[0009]

The above-mentioned disadvantages of the conventional automatic rotary takoyaki machine (i.e., lack of rotation function and variation in rotation function in a vibration type apparatus, and the center of a swing frame in a swing type apparatus). SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic rotary takoyaki machine which eliminates the lack of a rotating function in a region and has a simple structure.

Further, the conventional takoyaki plate has the disadvantages as described above (that is, the poor thermal efficiency of iron and the difficulty of keeping the takoyaki in a heat-retaining state with the takoyaki placed on the plate, and the thermal efficiency of copper. It is also an object of the present invention to provide a takoyaki plate from which the badness and the difficulty of forming the grilled hole deeply are eliminated.

[0011]

SUMMARY OF THE INVENTION A pit member having a hemispherical bottom and a deep recess having a cylindrical portion is made of a metal material having high heat conductivity, and is basically plate-shaped. A substrate member having an opening corresponding to the periphery of the cylindrical portion is made of a metal material having low thermal conductivity, and the periphery of the cylindrical portion of the grill member is joined to the periphery of the opening of the substrate member to form the grill member. And the substrate member are integrated into a takoyaki plate.

[0012] Further, as the automatic rotary takoyaki machine, a takoyaki plate having a deep recessed grilling hole, at least a movable frame carrying the takoyaki plate, and at least two rotatably supported by the takoyaki machine frame. The parallel rotation support shafts, a means for synchronizing the rotation phase of the rotation support shaft, a circular eccentric member eccentrically fixed to the rotation support shaft in the same phase, and the circular eccentric member fixed to the movable frame. A rotary bearing for rotatably holding, a drive unit for driving the rotation support shaft to rotate, and a control unit for controlling the drive unit are provided.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A typical example of the metal material of the pit member of the takoyaki plate of the present invention is copper, and a typical example of the forming process of the pit member is pressing from a circular copper plate. A typical example is stainless steel. A typical example of a technique for joining the peripheral edge of the cylindrical portion of the grill member to the peripheral edge of the opening of the substrate is a caulking technology of the peripheral edge of the cylindrical portion of the grill member.

[0014] The parallel rotary support shafts of an automatic rotary takoyaki machine are typically located on the same horizontal plane. Both ends of the rotation support shaft are supported by bearings of a pillow type unit. A typical example of the means for synchronizing the rotation phases is timing
A timing pulley that engages with the belt and supports the timing belt. The rotary bearing that rotatably holds the circular eccentric is typically a square flange bearing unit. The circular eccentric is typically fixed to the inner race of the bearing unit.

[0015] The movable frame typically also carries heating means (eg a gas burner). A typical example of the driving means is a three-phase 200
V motor. A typical example of the control means is a single-phase 100V-input three-phase 200V-output inverter, which is a manually-rotatable switch whose frequency can be switched in three stages.

[0016]

FIG. 5 shows a takoyaki plate 90 according to the present invention.
An example will be described. 5A is a plan view, and FIG. 5B is a cross-sectional view. In the figure, 14 is a substrate member made of stainless steel, 15 is a grilled hole member made of copper, and 16 is a caulking portion. In FIG. 5B, the grill member 15 is the substrate member 1.
4 are raised from FIG. 4 in order to emphasize that they are made of separate members. FIG. 6 is a detailed enlarged view of the cross-sectional view of FIG. 5B (the left side of the figure shows a state before caulking, and the right side of the figure shows a state after caulking). In the figure, reference numeral 18 denotes a step portion, and 16A denotes a peripheral portion in which the thickness of the pit member 15 is reduced to form the step portion;
9 is a cylindrical portion, 20 is a hemispherical bottom portion, and 21 is an opening in the stainless steel substrate member 14.

An opening 21 is formed in the stainless steel substrate member 14. On the other hand, the pit member 15 is formed by press molding from a copper disc material. The pit member 15 has a hemispherical bottom 20 followed by a cylindrical portion 19. The inner diameter of the cylindrical portion 19 is the same as the diameter of the inner surface of the hemispherical bottom 20. Cylindrical part 1
The axial length of 9 is slightly less than half of said diameter. However, a peripheral portion 16A for caulking extends from the peripheral edge of the cylindrical portion 19. The thickness of the peripheral portion 16A is thinner than the other portions, and a step portion 18 is formed on the outer periphery of the cylindrical portion 19 at the outer periphery. The outer diameter of the peripheral portion 16A is the same as the inner diameter of the opening 21 of the stainless steel substrate member 14, so that the peripheral portion 16A can be inserted into the opening 21. In FIG.
Numbers other than the above-mentioned reference numerals are dimensional values shown in mm. The axial length of the cylindrical portion 19 may be changed in a range of 2/3 to 4/3 times the radius r of the inner surface of the hemispherical bottom portion 20. When the dough 11 is fully filled in the grilling hole 8 having the cylindrical portion 19 having an axial length of 2 / 3r, the volume of the dough 11 is just twice as large as the volume of the hemispherical bottom portion 20 without overflowing the dough to the substrate 9. Can be baked into a perfect sphere.
If the axial length exceeds 4 / 3r, it becomes difficult to take out the burnt takoyaki, and the copper material is wasted.

Now, as shown on the left side of FIG.
A is inserted into the opening 21 so that the step 18 is
4, the peripheral portion 16 </ b> A is swaged to form the swaged portion 16 as shown on the right side of FIG. 6. The caulked portion 16 is drawn away from the substrate member 14 in FIG. 6, but is actually in close contact.

Thus, the takoyaki plate 90 of the present invention is provided.
Is formed.

Since the takoyaki plate 90 includes the stainless steel substrate member 14 and the copper making hole member 15, the copper making hole member 15 is individually press-molded, so that it is easy to make it deeper than the conventional making hole 8. Can be. The heat of the combustion energy from the gas burner spreads almost uniformly to the hemispherical bottom portion 20 and the cylindrical portion 19 of the pit member 15, and the heat supply (heat conduction) from the outside to the inside of the hemispherical bottom portion 20 is rapid, and the takoyaki is heated. Can be made quickly and the takoyaki can be turned over (ie, rotated) early. In addition, since the bottom of the grill hole is deep, the free surface of the dough not in contact with the hemispherical bottom portion 20 is baked by radiant heat, so that the umami steam can be confined in the takoyaki and bake deliciously. On the other hand, since the stainless steel substrate member 14 supporting the copper grilling member 15 has low thermal conductivity, the copper grilling member 15 is less likely to receive heat.
The fuel economy of the gas burner is therefore better than that of a plate made entirely of copper. In addition, the takoyaki plate of the present invention can start baking earlier than an iron takoyaki plate, and can quickly follow the temperature of the takoyaki plate according to the ignition and extinguishing of the gas burner, so that the takoyaki plate can be made of iron. It is more fuel efficient than the plate for the car.

FIG. 7 is a view for explaining the basic structure of the automatic rotary takoyaki machine according to the present invention. In the figure, 2
Reference numeral 2 denotes a circular eccentric member, reference numeral 23 denotes a rotary support shaft to which the circular eccentric member 22 is eccentrically fixed, reference numeral 24 denotes a pillow type bearing unit which rotatably supports the rotary support shaft 23 on a machine frame of a takoyaki machine, and reference numeral 25 denotes a rotary member. A timing pulley fixed to the support shaft 23, 26 is a timing belt stretched over two timing pulleys 25, 27 is a driving pulley,
28 is a drive motor.

FIG. 9 shows the rotation support shaft 23 and the circular eccentric member 22.
FIG. 3 is a diagram for explaining actual dimensional details of FIG. Although the eccentricity is 1.5 mm, the eccentricity can be changed in a range of 1 to 2 mm. If the amount of eccentricity is 1 mm or less, the rotation support shaft 23 must be rotated at a very high speed.
If the amount of eccentricity exceeds 2 mm, the runout of the takoyaki machine itself increases, which is not preferable.

Returning to FIG. 7, two parallel rotary support shafts 2
3 is rotatably mounted on the machine frame by four pillow-type bearing units 24. Each rotation support shaft 23 has two circular eccentric members 22 fixed in phase. The two rotary support shafts 23 are driven by a timing pulley 25 fixed to each end thereof and a timing belt 26 stretched over them so that the circular eccentric member 22 is brought into the same phase with respect to the machine frame. Are rotated synchronously. The rotation speed of the drive motor 28 is switched by the control means into four stages: off, low speed, medium speed, and high speed. This switching is performed by a manual rotary switch provided in the inverter.

FIG. 8 is a view for schematically explaining the movable frame 4 supported by the rotation support shaft 23 of FIG. FIG. 8B is a side view of the movable frame, and FIG. 8A is a perspective view. In the figure, 4 is a movable frame, 50 is a leg attached to the four corners of the movable frame 4, 17 is a rotary bearing mounted on the leg 50,
Reference numeral 22 denotes a circular eccentric member rotatably held by the leg 50 by the rotary bearing 17, and reference numeral 23 denotes a rotation support shaft that penetrates the circular eccentric member 22 eccentrically and is fixed to the circular eccentric member 22. Rotary bearing 1 for rotatably holding circular eccentric member 22
Reference numeral 7 denotes a square flange type bearing unit. The rotation support shaft 23 is rotatably supported on the machine frame by a pillow type bearing unit 24 as shown in FIG.

Thus, the movable frame 4 moves up, down, left, and right with respect to the machine frame, and even if attention is paid to any of the points α, β, and γ in FIG. It will be appreciated that they make equal circular motions.

The drive motor 28 is a 1/2 or 1/4 PH 200V three-phase motor, and has a single-phase 100V input three-phase two-phase motor.
The rotation is controlled by a 00V output inverter. The operator can select the speed in three stages, for example, low speed, medium speed, and high speed with a manual rotary switch that changes the frequency of the inverter (four stages including OFF). The rotation speed of the rotation support shaft 23 is preferably 500 to 2,000 rpm.

When the takoyaki is properly burned, the takoyaki plate is moved up, down, left and right at the first stage of low speed, then at the second stage of medium speed, and then at the third stage of high speed. The takoyaki is quickly rotated so that it can be roasted uniformly and neatly. Even at this high speed, the takoyaki is
Never jump out of. This is because it is made into a deep recessed pit (ie, has a cylindrical portion 19). When the takoyaki is baked, the heating power of the heating means is reduced,
In addition, the rotation speed of the drive motor is reduced, and the takoyaki is slowly rotated, so that the temperature of the takoyaki can be maintained to prevent the takoyaki from burning.

Since the deep concave grilling hole 8 is used, the takoyaki can be turned over quite automatically. In the conventional shallow grill 8, it is necessary to assist in starting the upside down. On the other hand, if you exercise strongly up, down, left, or right, you will jump out and you will have to replace it.

FIGS. 11 to 16 are views for explaining an automatic rotary takoyaki machine according to a second embodiment of the present invention.

The thickness of the spacer 4B is the same as the thickness of the center plate of the H-shaped movable frame 4. As can be seen from FIG. 15, one circular eccentric member 22 extending in the axial direction is rotatably held by two flange-shaped bearing units 17, and the two flange-shaped bearing units 17 are connected to the center plate of the movable frame 4. Is fixed to the movable frame 4 while sandwiching the lower part of the frame.

Even in such a configuration, the H-shaped movable frame 4 is supported on the machine frame 6 in a stable state without tilting with respect to the rotation support shaft 23 so as to be able to move up and down and right and left with certainty.

At first glance from FIG. 14, it looks like a two-point support of the center plate of the movable frame 4, but it is essentially a four-point support. What is shown in FIG. 7 is a clear four-point support of the movable frame. However, as shown in FIG. 10, three points can be supported.

In the automatic rotary takoyaki machine of the present invention, FIG.
As can be understood from the description of the circular motion at points α, β, and γ in (B) of FIG. In addition, since the vertical and horizontal movements are accurate circular movements, the takoyaki is accurately and reliably rotated in any area of the takoyaki plate, and there is no unevenness in the takoyaki baking.

A takoyaki plate having a shallow grilled hole 8 (ie, a conventional takoyaki plate) can also be used. In this case, the takoyaki is manually turned off once before operating the automatic rotary takoyaki machine. It needs to be repeated. However, no such assistance is necessary in the takoyaki plate of the present invention having a deep bottom pit.

The automatic rotary takoyaki machine of the present invention can be used not only for takoyaki but also for Akashiyaki similar to takoyaki. Suitable. In addition, those that expand as they are baked can be neatly baked into spherical shapes by putting a small amount of raw materials in the pits, and conversely, those that are shrinking by adding more raw materials to the pits. .

[0041]

The takoyaki plate of the present invention comprises a stainless steel substrate member 14 and a copper deep grilling member 15 fitted into the opening of the substrate member 14, so that the thermal power from the gas burner can be reduced. The firepower is quickly transmitted to the takoyaki dough inside, and the heat is less likely to be dissipated through the stainless steel substrate member 14. Therefore, the fuel efficiency of the gas burner can be greatly improved. In addition, the takoyaki dough in the deep grilled hole member 15 made of copper has the effect of quickly forming a skin and confining the umami of the takoyaki in the takoyaki, and making the takoyaki more delicious than a conventional takoyaki plate.

Further, in the automatic rotary takoyaki machine of the present invention, the takoyaki plate is moved up, down, left and right by the circular eccentric member, so that the movement speed can be accurately controlled. At low heat, it can be rotated slowly. Thus, the baking can be effected almost exactly to the desired quality.
