BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for cooling an object to be cooled such as a retort food while three-dimensionally transporting it in a liquid.

[0002]

2. Description of the Related Art For example, an object to be cooled, such as retort food, is cooled while being transported. The cooling method is roughly classified into an air cooling method and a water cooling method. There is.

The air cooling system includes natural air cooling and forced air cooling. The former natural air cooling is cooled by heat radiation to the atmosphere, so that the cooling rate is slow, and the latter forced air cooling is a device for generating cold air and cold air and outside air. A device to shut off the
The device becomes complicated and expensive.

Further, in the case of air cooling, the heat exchange rate is poorer than that of water cooling, and it takes a long time to cool to a predetermined temperature, which leads to the lengthening of the transfer conveyor during cooling.

[0005]

On the other hand, in the case of water cooling, since the heat exchange rate is high, the transportation distance is shorter than that of air cooling. In the case of air cooling, the object to be cooled can be continuously cooled while being carried on a conveyor, whereas for cooling the object to be cooled such as retort food by water cooling, the objects to be cooled can be simply put in a bucket. Since the method of putting in and cooling is adopted, it is a lot process, and after cooling, it is necessary to realign the objects to be cooled due to the post-process, and there is a problem that it is troublesome.

If the objects to be cooled are conveyed in a straight line in a line,
Although the above-mentioned problem of realignment can be solved, it is not economical in space, and it is required to make a three-dimensional structure to reduce the installation space of the device.

Therefore, for example, in the case of transportation in water, in order to avoid the complexity of the work in the subsequent process, it is necessary to transport them one by one as in the state before the cooling process and the required installation space. Due to the necessity of transporting in a small space, as shown in FIG. 7, the conveyors 102 and 103 are arranged in two stages in the water of the water tank 101, and the conveyors 102 and 103 in the two upper and lower stages are used to cover retort foods and the like. Although it is possible to cool the cooling object R while it is being conveyed, when the cooling object R is transferred from the downstream end of the upper conveyor 102 to the lower conveyor 103, the object R to be cooled may sink and float due to its specific gravity. Conveyor 102, lower conveyor 1
It was difficult to smoothly transfer between the No. 03 belt portions 102A and 103A.

Further, as shown in FIG.
When the water tank 101 is tilted and placed in the water in the water tank 101, in the water, the objects R to be cooled may float or sink due to their specific gravities, which may overlap or solidify in one place. R is in a state of not being aligned, and it is difficult to convey R while keeping the state of being aligned one by one.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to simplify the structure of the apparatus and to reliably transport the objects to be cooled in an aligned state. An object of the present invention is to provide a cooling device by three-dimensional transportation.

[0010]

The invention according to claim 1 is
In the liquid tank, multiple conveyors are installed in which the object to be cooled that floats due to the buoyancy of the liquid is wound around the driving wheel and the driven wheel, and is sandwiched between the vertically facing conveyor belts. A guide for guiding and moving the object to be cooled along the transfer section was provided at the transfer section at the downstream end of the upper conveyor among the plurality of conveyors, which transfers to the lower conveyor. Is characterized by.

According to a second aspect of the present invention, in the first aspect of the present invention, an unloading conveyor is arranged in which the one end is connected to the downstream side of the lowermost conveyor and the other end is located outside the liquid tank. A guide conveyor is arranged opposite to the carry-out conveyor to sandwich the object to be cooled by the carry-out conveyor.

According to a third aspect of the present invention, in the first aspect of the present invention, the carry-in conveyor, one end of which is connected to the upstream side of the uppermost conveyor and the other end of which is located outside the liquid tank, is arranged in an inclined manner. A guide conveyor is arranged opposite to the carry-in conveyor to sandwich the object to be cooled by the carry-in conveyor.

[0013]

In the invention according to claim 1, the object to be cooled is
When it is conveyed from the upstream side to the downstream side by the upper conveyor of the plurality of conveyors and reaches the transfer section at the downstream end of the upper conveyor, the upper conveyor and the lower conveyor are guided by the guide provided in the transfer section. It is inserted and sandwiched between the conveyor belts facing each other on the conveyor, and even if it tries to float due to the buoyancy of the liquid, it is pressed down by the upper conveyor,
They are transported in an aligned state.

According to the second aspect of the present invention, the object to be cooled is conveyed by the unloading conveyor arranged obliquely, but even if the object to be cooled is floated by the buoyancy of the liquid, it is pressed by the guide conveyor. Therefore, they are transported in an aligned state.

Even when the object to be cooled is about to sink,
Since it is pushed in by the guide conveyor, it is conveyed in an aligned state. According to the third aspect of the invention, the same operation as that of the second aspect of the invention occurs.

It is supplied so as to be sandwiched by 7B and guided to the upper conveyor 3 in a state of being sandwiched between the net-shaped belt 2A and the toothed belt 7B.

In the upper conveyor 3, the object R to be cooled is pressed from the net-shaped belt 3A of the upper-stage conveyor 3 by an appropriate pressing means and is pushed by the net-shaped belt 3A from left to right in the drawing. It is transported and cooled by the cooling water in the water tank 1. The object R to be cooled reaches the transfer section 39 at the downstream end of the upper conveyor 3.

In the transfer section 39, the object R to be cooled is guided by the guide 4
By driving the toothed belt 42 of 0 and the net belt 3A along the circumference of the drive pulley 3C of the upper conveyor 3, the net belt of the upper conveyor 3 is guided while being prevented from floating and sinking due to its specific gravity.

Alternatively, it may be configured by a combination thereof. For example, as shown in FIGS. 5 and 6, it is possible to configure a cooling device in which five stages of conveyors 51, 52, 53, 54, 55 are arranged in five rows.

In this case, the transfer section 56 at the downstream end of the upper conveyor consisting of the first conveyor 51 transfers to the lower conveyor consisting of the second conveyor 52,
6, a first guide 56A is provided, and a transfer section 57 for transferring to a lower stage conveyor made up of the third stage conveyor 53 at the downstream end of the upper stage conveyor made up of the second stage conveyor 52.
Is provided with a second guide 57A along the transfer section 57. Similarly, the third guide 58A is attached to the transfer section 58 of the third-stage conveyor 53 and the fourth-stage conveyor 5

[0044]

As described above, according to the first aspect of the invention, the object to be cooled such as the retort food is conveyed while being sandwiched between the conveyor belts facing each other of the upper and lower conveyors of the plurality of conveyors. Since the objects to be cooled can be conveyed in an aligned state, the objects to be cooled in the liquid are prevented from floating, coming off the conveyor, and overlapping, and the objects to be cooled in the liquid are buoyant. It is possible to transport one by one securely in an aligned state without being affected by liquids or liquids. As a result, even when it is carried in water, it can be carried out in the same state as that before the cooling step.

Since a guide is formed along the transfer section at the transfer section at the downstream end of the upper conveyor to transfer to the lower conveyor, for example, the object to be cooled is transferred to the upper conveyor. From the department to the lower conveyor,
Even if the object to be cooled floats or sinks, the object to be cooled can be smoothly transferred from the transfer section of the upper conveyor to the conveyor belt of the lower conveyor by being guided by the guide.

Therefore, since a plurality of conveyors can be arranged in multiple stages in the liquid, the length of the conveyor in the horizontal direction can be shortened, and the cooling device for three-dimensional transportation in the liquid can be made compact.

According to the second aspect of the present invention, in addition to the above effects, it faces the unloading conveyor which is inclined.
Since the guide conveyor for sandwiching the object to be cooled is arranged between the carry-out conveyor and the carry-out conveyor, the object to be cooled such as the retort food can be sandwiched between the carry-out conveyor and the guide conveyor and can be conveyed in an aligned state. The objects to be cooled can be prevented from floating, coming off the conveyor, and overlapping, and can be conveyed in an aligned state one by one.
