When being conveyed along the conveyance path, the container support sequentially takes in the power signals from the power supply lines via the current collector, and sequentially supplies these power signals to the motor. .

[0006]

According to the present invention, when the container support is conveyed, it sequentially passes in the vicinity of each power feed line, and the power collection unit sequentially takes in the power signals of each power feed line, and these power signals are fed to the motor. Supply sequentially. Here, as a power signal of each power supply line, if a motor that can appropriately set the rotation speed and rotation direction of the motor is prepared in advance, this motor will operate in accordance with each power signal. Since it rotates by, the stirring mode in the container by the power of this motor can be changed each time.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 schematically shows an embodiment of the stirring cooking apparatus according to the present invention. In the figure, a plurality of container supports 1 are sandwiched and supported by a set of chains 2, and these chains 2 are hung on a plurality of sets of sprockets 3, whereby a substantially rectangular transport path is formed. Has been formed. At least one set of these sets of sprockets 3 is driven, whereby each container support 1 is transported along this transport path, and the material input zone A, the heating zone B, the removal zone C, and the cleaning zone are washed. Pass through Zone D in sequence. In addition, a power feeding line 4 is arranged along this transport path, and each container support 1
Takes in a power signal from the power supply line 4 and performs a stirring operation described later.

FIG. 2 schematically shows each container support 1 and the power supply line 4 when viewed from above. As is clear from this figure, the power supply line 4 is formed by arranging three lines in parallel and is divided into each of the sections X1, X2 and X3. That is, in the area X1, each line 4-1a,
4-1b and 4-1c are laid, and lines 4-2a, 4-2b and 4-2c are laid in the section X2, and lines 4-3a, 4-3b and 4-3c are laid in the section X3.
Has been laid.

A first power source 5, a second power source 6 and a third power source 7 are provided for each of these zones X1, X2 and X3, and these power sources 5, 6 and 7 are provided for each zone X1, X2, X3,
Three-phase AC voltage is applied to each of the three lines.
Each container support 1 takes in three-phase AC voltage from three lines in each zone X1, X2, X3 and supplies the three-phase AC voltage to the three-phase AC motor 8 for stirring operation. The phase AC motors 8 are respectively rotated.

Here, for example, from the first power source 5, the frequency 9
The three-phase AC voltage of 0 Hz is output, the three-phase AC voltage of frequency 50 Hz is output from the second power supply 6, the three-phase AC voltage of frequency 60 Hz is output from the third power supply 7, and so on. If the frequencies are different, the three-phase AC motors 8 of the container supports 1 are connected to the zones X1, X2, X3.
Each time, it rotates at the number of rotations corresponding to the frequency of the three-phase AC voltage. In addition, the power supplies 5, 6, and 7 appropriately set the phase sequence of the AC voltages applied to the three lines. As a result, if the motor 8 of each container support 1 is normally rotated in the zone X1, for example, it will be reversely rotated in the zone X2 and will be normally rotated again in the zone X3.

Therefore, the motor 8 of each container support 1
Rotates in the zone X1 at a rotation speed corresponding to a frequency of 90 Hz, in the zone X2 at a rotation speed corresponding to a frequency of 50 Hz, and in the zone X3 at a rotation speed corresponding to a frequency of 60 Hz.

In order to form each area as shown in FIG. 2, the power supply line 4 shown in FIG. 1 is appropriately divided and each power source is provided. For example, the power supply line 4 is divided in the heating zone B, each power source is provided, and the motor 8 of each container support 1 is normally or reversely rotated at a desired rotation speed for each area.

The power supply line 4 shown in FIG. 1 may be partially laid along the transport path as needed, and need not be entirely laid.

FIG. 3 shows the container support 1 as seen from above, and FIG. 4 is a sectional view taken along the line III--III of FIG. As shown in these figures, a pair of chains 2 are guided and moved by respective chain guides 10. The container support 1 is sandwiched between the chains 2, and both ends of the container support 1 are connected to the connecting pieces 1 respectively.
It is connected to each chain 2 via 1. This connection is made so that the container support 1 has a required inclination with respect to each chain 2. Therefore, as shown in FIG. 1, each container support 1 faces the upper left side when passing the upper side of the transport path, faces the lower left side when passing the left side of the transport path, and moves the lower side of the transport path downward. When it passes, it faces to the lower right side, and when it passes on the right side of the transport route, it faces to the upper right side.

Further, as shown in FIGS. 3 and 4, the container support 1 has plate bodies 12a and 12b at the top and bottom.
The upper plate 12a is provided with an insertion hole 13,
A cylindrical container 14 is inserted into the insertion hole 13.
Here, two containers 14 are arranged side by side. Further, a total of six rollers 15 are provided on the upper plate 12 a along the edges of the two insertion holes 13.
Two containers 14 are rotatably supported by 5.

Although the container support 1 supports two containers 14, it may support one or three or more containers. Further, the number of containers in this cooking device may be set arbitrarily according to the amount of food produced.

On the side wall of the container support 1, a current collecting arm 16 is provided in a protruding manner, and below the arm 16,
Three guide pillars 17 corresponding to the three rails 4a, 4b, 4c are fixed. These guide columns 17 include a base portion 17 a fixed to the current collecting arm 16 and the base portion 1 a.
The oscillating portion 17b is inserted into the 7a, the coil spring 17c urges the oscillating portion 17b downward, and the conductive brush 17d attached to the lower side of the oscillating portion 17b. Below these guide posts 17 are three rails 4
a, 4b, 4c are located respectively, and these guide columns 1
Since the swinging portion 17b of 7 is biased downward, the conductive brushes 17d on the lower side of the guide columns 17 are pressed against the rails 4a, 4b, 4c. Therefore, each of the rails 4a, 4b, 4 is passed through these guide pillars 17.
A three-phase AC voltage can be taken from c, and this three-phase AC voltage is supplied to the motor 8 of the container support 1 via a cord (not shown).

FIG. 5 is a partially enlarged view of the cross section of FIG. As is clear from this figure, a cylindrical shaft 21 is provided on the bottom lower surface of the container 14, and the shaft 21 is inserted into a bearing cylinder 22 attached to the lower plate 12b to be rotatable. It is supported. The motor 8 is attached to the shaft 21.
Is transmitted via the torque transmission mechanism.

As the torque transmission mechanism, any mechanism can be adopted. Here, as shown in FIG. 6, the sprockets 23 and 24 are attached to the rotary shaft of the motor 8 and the shaft 21 of each container 14, respectively. , These sprockets 2
Chain 2 is stretched between 3 and 24, and two containers 14
Are rotating in the same direction.

A stirring shaft 26 is rotatably inserted inside the shaft 21, and a stirring blade 27 that is rotated in the container 14 is attached to the upper side of the stirring shaft 26. Only the one-way rotation of the shaft 21 is transmitted to the stirring shaft 26 via the one-way clutch 28.

FIG. 5 shows a cross section of the one-way clutch 28, and FIG. 7 shows one surface along II-II of FIG. 5 as viewed from below. In this one-way clutch 28, a cylindrical portion 31 is provided on the lower surface of the sprocket 24, and a disc 33 housed in the cylindrical portion 31 is attached to the lower side of the stirring shaft 26.
A notch 35 that forms a wedge space 34 between the rolling element 36 and the rolling element 36 is formed on the outer peripheral portion of the disc 33.
The elastic member 3 for pressing the wedge toward the narrow portion of the wedge space 34
7 and 7 are incorporated.

In this one-way clutch 28, when the sprocket 24 is rotated in the direction of the arrow in FIG. 7 by driving the motor 8, the rolling element 36 moves to the narrow portion of the wedge space 34 and the inner peripheral surface of the cylindrical portion 31. Also, the rotation of the sprocket 24 is transmitted to the disc 33 via the rolling elements 36 by engaging with the surface of the notch 35, and the stirring blade 27 rotates.

When the sprocket 24 is rotated in the opposite direction, the rolling element 36 moves toward the wide portion of the wedge space 34, so that the disc 33 idles and the stirring blade 27 does not rotate. At this time, in order to securely stop the stirring blade 27, the support piece 38 is disposed on the upper plate 12a as shown in FIGS. 3 and 8, and the stopper shaft 39 is swung on the support piece 38 via the pin 41. It is movably mounted and the projection piece 42 is attached to the support piece 3
It is provided in 8. Here, when the stirring blade 27 comes into contact with the stopper shaft 39 as the stirring blade 27 rotates in the opposite direction,
Although the stopper shaft 39 swings, the stopper shaft 39
Is prevented by the protrusion 42, and as a result, the rotation of the stirring blade 27 in the opposite direction is reliably stopped.

Therefore, when the container 14 is rotated in one direction by driving the motor 8, the stirring blade 27 is also rotated in the same direction together with the container 14, and the container 14 is rotated.
When is rotated in the opposite direction, the stirring blade 27 stops without rotating.

On the other hand, as described above, when the container support 1 is conveyed, the motor 8 is set to 3 for each predetermined zone.
Forward rotation or reverse rotation is performed at a rotation speed corresponding to the frequency of the phase alternating voltage. Therefore, for each of these areas, the container 14 and the stirring blade 27 are rotated in one direction at a rotation speed corresponding to the frequency of the three-phase AC voltage, or only the container 14 is rotated at the rotation speed corresponding to the frequency of the three-phase AC voltage. Can be rotated in the opposite direction.

In the stirring and cooking apparatus having such a structure, when one of the container supports 1 shown in FIG. 1 passes through the material charging zone A, the two containers 14 of the container support 1 are separated from each other. The ingredients and seasonings introduced through the ingredient guide 43 are introduced. At this time, each container 14
Since it is not necessary to rotate the power supply line 4, the power supply line 4 in the zone A may be omitted.

Next, as the container support 1 passes through the heating zone B, each container 14 of the container support 1 is heated by the gas burner 44 arranged in this zone B. In the heating zone B, a power supply line 4 is laid, and the power supply line 4 is divided into a plurality of areas as needed, and each of these areas is supplied with a three-phase AC voltage for the container support 1. Supply to. As a result, each container 14 and each stirring blade 27 rotate in one direction at the number of rotations corresponding to the frequency of the three-phase AC voltage, or each container 14 receives the three-phase AC voltage with each stirring blade 27 stopped. It rotates in the opposite direction at the number of rotations corresponding to the frequency. As a result, the materials and seasonings in each container 14 are heated while being stirred.

Now, with each stirring blade 27 stopped,
When each container 14 is rotated in the opposite direction, the material adhering to the inner wall of the container 14 is scraped off by the stirring blade 27, so that cooking can be rapidly advanced. Further, since the container 14 is entirely heated by the rotation of the container 14, the material inside the container 14 is also heated well. In comparison with this, in the conventional cooking device described above, since the stirring blade rotates inside the container and the container is fixed, the container tends to be partially heated and the inner wall of the container tends to be heated. It is easy for the deposits to stick to. Further, since the rotating shaft of the stirring blade located at the center of the bottom of the container is intensively heated, the durability of this rotating shaft is poor.

In this way, the materials in each container 14 are cooked, and by the time this cooking is completed, the container support 1 reaches the take-out zone C. Here, since each container 14 faces the lower left side, the material in these containers 14 falls, is received by the guide chute 45, and is guided to a predetermined position through this chute 45. At this time, by rotating each container 14 with each stirring blade 27 stopped, the material in each container 14 can be easily dropped. Therefore, in this zone C, the power feeding line 4 is laid, and in this power feeding line 4, with each stirring blade 27 stopped,
A three-phase AC voltage for slowly rotating each container 14 is applied.

Next, the container support 1 faces the lower right side and reaches the cleaning zone D. In this cleaning zone D, high-pressure cleaning water is sprayed from the spraying section 46 into each container 14 to clean the inside of these containers 14. Further, in order to efficiently carry out this cleaning, each container 14 is rapidly rotated with each stirring blade 27 stopped, and the power supply line 4 for supplying the three-phase AC voltage for this purpose is connected to the cleaning zone D.
Is laid in.

By the way, in the above-mentioned embodiment, in order to rotate the motor of the container support body forward and backward at an appropriate number of revolutions,
A three-phase AC motor is used to supply the three-phase AC voltage to the motor, but the present invention is not limited to this.
For example, it is possible to use a DC motor that changes its rotation speed according to the applied voltage and rotates normally and reversely depending on the polarity, or a two-phase AC motor that has the functions of normal rotation and reverse rotation.

Although a conductive brush is used to take in power from the power supply line, a conductive roller, pantograph or the like may be applied instead.

Further, in order to stir the material in the container,
The container and stirring blade are rotated, or the container is rotated with the stirring blade stopped, but only one of the container and stirring blade rotates, or the number of rotations of the container depends on the cooking ingredients. The present invention can be applied even if it is kept constant without changing or the mechanism for stopping the stirring blade by reversing the container is omitted.

Before the material charging zone A , preheating is performed.
A zone can be provided, and the material charging zone A can also be used as a zone for preheating.

Further, the transportation method is such that the container supports 1 are aligned without using a chain, and they are sequentially pressed with a pusher or the like.
It can be arbitrarily selected such as transferring to the front, and the shape of this path can be freely set.

[0037]

As described above, according to the present invention, when the container support is transported, the container support sequentially receives the power signals from the power supply lines and sequentially supplies the power signals to the motor. ing. Therefore, this motor rotates at the number of rotations and the direction of rotation according to each power signal,
The stirring mode in the container is sequentially changed. Therefore, if cooking is advanced during the transportation of the container support, the materials in the container can be appropriately agitated as the cooking is advanced.
