Description

[Detailed Description of the Invention] The present invention relates to a device that facilitates the removal of cooked rice from the container when the rice cooking container is turned over and the cooked rice inside the container is taken out of the container.

Since large amounts of rice are required at group lunch stations, the rice is cooked in a rice-cooking container that is heated while being transported on a conveyor, and after the rice is cooked, the rice-cooking container is turned over and the rice inside is removed.

Rice-cooking containers are made of fluororesin, which is referred to by trade names such as Teflon, which is a non-adhesive resin, for the purpose of preventing cooked rice from adhering to the inner surface and making it easier to clean. coats the inner surface of the

Therefore, when the amount of cooked rice is small, the contact area between it and the side wall of the rice cooking container is small, and the cooked rice comes out simply by inverting the rice cooking container.

However, when there is a large amount of rice after cooking, the contact area between the rice and the inner surface of the side wall of the rice-cooking container is large, and the rice is already filled, so it is not possible to simply turn the container over and the rice will come out. There may be cases where this is not the case.

In such a case, there is a device disclosed in Japanese Patent Application Laid-Open No. 5381640 to make it easier to take out the cooked rice. Both sides of the fitting part are biased in the same direction by springs.

Therefore, when inserting the peeling plate into the rice-cooking container, the peeling plate swings in both directions of its thickness, which may cause the peeling plate to separate from the inner surface of the rice-cooking container and move through the cooked rice. There are some difficulties.

The object of the present invention is to make it possible to reliably insert a plate along the inner surface of the side wall of a rice cooking container.

The device of the present invention has a frame fixed horizontally above a conveyor that transfers rice-cooking containers, and a guide made of an almost vertical plate or rod is fixed to the bottom surface of the frame, so that the axis is vertical. A support shaft that penetrates the frame and moves up and down; a support that is fixed horizontally to the bottom of the support shaft; the rocking plate, and the upper side of the rocking plate than the connecting part is biased by a spring in the direction of the support shaft, and the rocking plate is in a position where it overlaps the outside of the guide in a parallel state. A flexible plate with appropriate rigidity is fixed to the lower end of the swinging plate in parallel with it, and with the swinging plate in contact with the guide, the lower part of the flexible plate is inserted into the mouth of the rice cooking container. This device is insertable, and the length of the guide is set so that the rocking plate separates from the guide after the lower end of the flexible plate is inserted into the mouth of the rice cooking container. When the rice-cooking container stops at the bottom, the flexible plate is inserted into the mouth of the rice-cooking container by lowering the support shaft.

At this time, the rocking plate is joined to the guide. When the flexible plate further descends and the rocking plate separates from the guide, the flexible plate moves outward by the force of the spring and comes into contact with the inner surface of the side wall of the rice cooking container.

In this state, the flexible plate is inserted to the bottom of the rice cooking container.

To explain this with reference to the embodiment shown in the drawings, 1 is a conveyor that transports rice-cooking containers in a suspended state.A pair of conveyors are arranged in parallel at a distance that allows the handle of the rice-cooking container to be supported, and the conveyor moves intermittently. .

2 is a frame fixed horizontally above the conveyor 1; 3 is a guide fixed to the bottom surface of the frame 2 and protruding downward; It is supposed to be located.

Any material such as a plate or a rod can be used as the guide 3, but when it is a plate, it is oriented parallel to the side wall of the rice cooking container.

In this embodiment, the guides 3 are provided corresponding to the three side walls of the rectangular rice cooking container, as is clear from FIG. 2, but the number of guides 3 may be set at one or two locations as desired. .

Reference numeral 4 denotes a support shaft located at the center in the width direction of the conveyor 1 and attached perpendicularly to and passing through the frame 2, and this is forcibly moved up and down.

5 is a support fixed horizontally to the lower end of the support shaft 4;
This is large enough to fit inside the guide 3.

Reference numeral 6 denotes a rocking plate attached to the circumferential surface of the support 5 facing the guide 3 at an intermediate portion in the vertical direction. It is elongated in a direction parallel to the side wall of the rice cooking container that stops at the bottom.

Then, when the support shaft 4 rises, the swing plate 6 has its upper end overlapped with the outside of the guide 3 and becomes almost vertical, and its lower end is located outside the rice cooker stopping below. It is located near the inside.

Therefore, the lower end of the guide 3 and the upper end of the swing plate 6 are curved in opposite directions to facilitate overlapping with each other.

Reference numeral 8 denotes a spring whose one end is attached to the support 5 in order to bias the upper end side of the swing plate 6 in the direction of the support 5;
In this embodiment, the swing plate 6 has a rim on its upper side, so one end is attached to a rod 9 fixed to the lower part of the swing plate 6.

However, by making the upper part of the swing plate 6 wider than the guide 3,
It is also possible to provide a spring 8 between the support 5 and the rocking plate 6.

Reference numeral 10 denotes a flexible plate fixed to the lower end of the rocking plate 6 so as to protrude downward from the lower end of the swing plate 6. As a flexible and rigid plate, it can be inserted between the rice cooking container and the rice along the inner surface of the side wall.

When the support shaft 4 is raised, the lower end of the flexible plate 10 is positioned slightly higher than the rim of the rice cooking container.

If the flexible plate 10 is made of fluororesin, it is suitable for preventing cooked rice from adhering to the flexible plate 10 and allowing easy insertion into the rice cooking container.

By the way, when using a fluororesin plate, it is 6 to 10 mm.
As long as it was thick enough, it could achieve its purpose.

It is also possible to use a rubber plate or a synthetic resin plate whose surface is coated with fluororesin.

It is suitable that the lower edge of the flexible plate 10 be made thin like a knife, but this limitation is not necessary.

Reference numeral 11 denotes a switch mounting plate erected on the side of the support shaft 4 on the upper side of the frame 2. Limit switches 12 and 13 are mounted on the upper and lower parts of the mounting plate, and an operating body 14 for operating them is attached to the support shaft 4. is fixed to the top edge of the

By operating the limit switches 12, 13, the motor 15 that moves the support shaft 4 up and down is stopped or reversed.

The motor 15 is driven when lowering the support shaft 4 by operating a limit switch (not shown) on a rice cooker that is stopped below it.

16 is a rice cooking container. In this device, when the rice-cooking container filled with cooked rice transferred by the conveyor 1 below stops, the motor 15 is driven and the support shaft 4 starts lowering.

As the support shaft 4 descends, the swing plate 6 and flexible plate 10 descend along the guide 3 via the support 5 attached to it, and the lower end of the flexible plate 10 enters the mouth of the rice cooking container. .

In this state, if the descent continues further, the rocking plate 6 will move from the guide 3.
are separated, and the rocking plate 6, as shown by the chain line in FIG. , the lower end of the flexible plate 10 is pressed against the inner surface of the side wall of the rice cooking container by the force of the spring 8.

That is, the flexible plate 10 is inserted into the rice cooking container with its lower portion pressed against the inner surface of the side wall, and separates the cooked rice from the inner surface of the rice cooking container.

When the support shaft 4 descends within a predetermined range, it then rises and then stops.

As the support shaft 4 rises, the upper part of the swing plate 6 overlaps the outside of the guide 3, and everything returns to its original state.

When the support shaft 6 descends and the rocking plate 6 separates from the guide 3, the upper part of the rocking plate 6 moves in the direction of the guide 3, but at that time, the lower part of the flexible plate 10 is already in the rice cooking container. Since the rocking plate 6 is supported and prevented from rotating beyond a certain level, by bending the upper end of the guide 3 and the upper end of the rocking plate 10 in opposite directions, the rocking plate 10 can be prevented from rotating beyond a certain level. When raised, its upper end overlaps the outside of the guide 3.

However, a stopper may be made to protrude from the support body 5 toward the rocking plate 6 above the hinge 7, and the rocking plate 6 may be supported by it, or the rocking plate 6 may be directly supported at the upper end of the support body 5. By doing this, the upper part of the swing plate 6 can be more reliably placed on the outside of the guide 3.

2, this device inserts the flexible plate 10 into the rice cooking container by lowering the support shaft 4, and then makes it easy for cooked rice to come out. When the rice-cooking container is in use, the fixed guide 3 supports the upper end of the swing plate 6, so the swing plate 6 can move toward the center of the rice-cooking container, but cannot move toward the outside of the rice-cooker. It is impossible.

Therefore, even if the swing plate 6 is hit by another obstacle, the flexible plate 10 can always be reliably inserted into the rice cooking container.

After inserting the flexible plate 10 into the mouth of the rice cooking container, the swing plate 6 is separated from the guide 3, and the lower end of the flexible plate 10 is pressed against the inner surface of the side wall of the rice cooking container by the force of the spring 8. The flexible plate 10 is inserted into the rice cooking container in this state, and the spring 8 is provided only above the pivoting part of the swing plate 6,
0 is always biased only outward.

Therefore, the flexible plate 10 is inserted into the rice cooking container along the inner surface of the side wall and between it and the cooked rice, and is used to crush the cooked rice or press the cooked rice against the side wall of the container so that it remains inside the container. The rice can be separated from the side wall of the rice-cooking container without causing any trouble, and the rice can be reliably served by reversing the container.

As in the embodiment, it is suitable to provide the flexible plate 10 over a wide area of the side wall of the rice-cooking container, but if the inner surface of the rice-cooking container is coated with fluororesin, it is possible to provide the flexible plate 10 over a wide area of the side wall of the rice-cooking container, since there is no adhesion of cooked rice. good.
