DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver production apparatus for producing sheet laver.

[0002]

2. Description of the Related Art At present, a laver production apparatus which is widely used includes a laminating section for laminating raw laver on a laver, a dehydrating section for dehydrating the raw laver, and a laver cage. While transporting the transport path in the posture, it is composed of a drying chamber that blows warm air from the bottom to the upper part or blows down from the upper part to the lower part to dry raw seaweed, and transports the sea laver on the transport path. Automatic production of thousands of laver every hour.

[0003] As described above, the raw laver is dried by blowing hot air from the lower part to the upper part or by blowing it down from the upper part to the lower part while conveying the laver in a vertical position on the conveying path. It has become. Therefore, in the method of blowing warm air from the lower part to the upper part, the raw nori is easier to dry in the lower part than in the upper part, so that the upper part of the nori is dried from the drying chamber. There was a problem that it was easily sent out. On the contrary,
In the case of blowing down hot air from the upper part to the lower part, the raw nori is easier to dry in the upper part than in the lower part. There was a problem that it was easily sent out.

Therefore, conventionally, an operator takes the seaweed sent out of the drying chamber by hand and visually judges the quality of the dried state. If the dried state is poor, the temperature of the drying chamber or the air volume is adjusted to perform the drying. The occurrence of unevenness was eliminated.

[0005]

However, in the above-mentioned conventional means, there is a problem that the operator often has to judge whether the dried state is good or not by using the laver as a hand, which is extremely troublesome. In addition, there is a problem that individual differences are likely to occur in the determination of good or bad, and if the user forgets to make the good or bad determination, a large amount of defective laver with uneven drying is produced.

Accordingly, it is an object of the present invention to provide a laver manufacturing apparatus provided with a means for easily detecting the presence or absence of uneven drying.

[0007]

For this purpose, the present invention provides a first temperature sensor 21 and a second temperature sensor 22 at the upper and lower portions of the laver cage 13 which is transported along the transport path 2 of the drying chamber 1. The presence / absence of drying unevenness is determined from the temperature difference between the ambient temperatures detected by the temperature sensors 21 and 22.

[0008]

According to the above construction, the presence or absence of uneven drying can be easily detected by the first temperature sensor 21 and the second temperature sensor 22, and when the uneven drying is detected, the drying chamber 1 is immediately turned on.
By controlling the temperature, etc., the occurrence of uneven drying can be eliminated.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the laver manufacturing apparatus. Reference numeral 1 denotes a drying chamber, in which an endless chain 2 constituting a transport path of laver is tuned horizontally to a sprocket 2a, and the endless chain 2 rotates in the direction of the arrow. Endless chain 2
A large number of skeletons 3 are attached at equal pitches to each other, and a laver holder 4 is held between the skeletons 3 in a vertical posture. An opening 10 is opened in the lower part of the drying chamber 1, and warm air is blown from the opening 10, and the warm air blows up from the lower part to the upper part as shown by a dashed arrow.

FIG. 2 is a front view of the laver holder 4 conveyed by the endless chain 2 near the exit 1b at the lower front of the drying chamber 1. The laver holder 4 is a long horizontal rod 1
1 and a short vertical rod 12 are assembled in a frame shape, and a plurality of laver cages 13 are held by stoppers 14. Reference numeral 15 denotes laver attached to the laver cage 13.

In FIG. 1, reference numeral 5 denotes an endless chain disposed at the front of the drying chamber 1, which rotates in the direction of the arrow along the sprocket 5a. A washing unit 6, a paper making unit 7, and a dewatering unit 8 are provided side by side at the upper part of the rotation path of the endless chain 5, and a peeling part 9 is provided at the lower part. The washing unit 6 sprays water on the laver cage 13 to wash it. The paper-making part 7 is a laver cage 13
The raw laver is made into a sheet on top. The dewatering unit 8 press-dehydrates the seaweed machined on the laver cage 13. The laver holder 4 that holds the press dewatered laver 13 is
It is fed between the supporting bones 3 rotating in the drying chamber 1 from the entrance 1a at the upper front part of the drying chamber 1. The peeling section 9 peels off the laver 15 attached to the laver cage 13 held by the laver holder 4 sent from the outlet 1b of the drying chamber 1 from the laver cage 13.

In FIG. 1, a first temperature sensor 21 and a second temperature sensor 22 are provided on the transport path of the laver 13 near the exit 1b in the drying chamber 1. The first temperature sensor 21 is installed on the upper part of the laver 13 transported on the transport path, and the second temperature sensor 22 is disposed on the lower part (see also FIG. 2). The temperature sensors 21 and 22 are for measuring the ambient temperature. For example, inexpensive temperature sensors such as thermocouples can be used.

FIG. 3 is a block diagram of the control circuit. First
The temperature sensor 21 and the second temperature sensor 22 are connected to a control unit 23 such as a microcomputer, for example.
Is connected to a notification element 24 such as a buzzer.

Next, a method for determining the presence or absence of uneven drying will be described. In FIG. 2, the warm air blows up from the lower part to the upper part as indicated by a broken arrow, so that the lower part of the laver 15 is easier to dry than the upper part, so that the upper part is not dried and uneven drying occurs. It is easy to do so as described above.

By the way, when the seaweed 15 contains a lot of water, the temperature of the hot air decreases due to heat of vaporization of the water. Hardly deprived, and the warm air hardly cools. The present invention has been made focusing on this point. That is, when the lower part of the laver 15 is dried and the lower part contains little water, and the upper part is late and the upper part contains much water, much heat of vaporization is taken away in the upper part. Therefore, if the detected temperature of the first temperature sensor 21 in the upper part of the seaweed cage 13 is lower than the detected temperature of the second temperature sensor 22 in the lower part, and there is a temperature difference between the two, the upper part of the seaweed 15 will not contain much moisture. It can be determined that it is in a dry state.
Therefore, from the magnitude of this temperature difference, the degree of unevenness in drying of the upper and lower portions is determined by the control unit 23, and if the temperature difference is large,
The notification element 24 notifies the worker to that effect.

This laver manufacturing apparatus is configured as described above, and the operation will be described below. In FIG. 1, while the laver holder 4 is transported by an endless chain 5, raw laver is made into a laver cage 13 in a paper making section 7, and then the raw laver is dehydrated in a dehydrating section 8, and the laver holder 4 is removed. Is fed from the inlet 1a between the supporting bones 3 rotating between the drying chambers 1 between the drying chambers 1. The laver holder 4 adheres to the laver cage 13 by being transported in the drying chamber 1 in the direction of the arrow. The raw nori is gradually dried.

The laver cage holder 4 is transported toward the outlet 1b of the drying chamber 1, and the ambient temperature is detected by a first temperature sensor 21 and a second temperature sensor 22 installed in front of the outlet 1b. You. When the temperature difference is large, it is determined that the drying of the upper part of the laver 15 is delayed and contains a lot of water as described above, and it is determined that there is uneven drying in the upper part and the lower part. Notify to the effect. Therefore, the worker eliminates the occurrence of uneven drying by adjusting the temperature of the drying chamber 1 and the air volume. The dried laver holder 4 is sent out from the outlet 1b to the endless chain 5, and the laver 15 is peeled off from the laver cage 13 at the peeling section 9. This laver cage 13 is sent to the washing unit 6 as it is, where it is washed, and then sent to the paper making unit 7 again, and the above-described operation is repeated.

It is desirable that the first temperature sensor 21 and the second temperature sensor 22 are installed at a position where the temperature difference between the upper part and the lower part of the laver 15 becomes remarkable. The position before the exit 1b of the chamber 1 is a good position, but the installation position is not limited to this position. Further, in order to eliminate a temperature detection error, temperature detection may be performed at a plurality of locations to obtain an average value, and the presence or absence of drying unevenness may be determined from the difference between the average values. Can be considered.

FIG. 4 is a side view of a laver manufacturing apparatus according to a second embodiment of the present invention. In the first embodiment, the opening 10 is opened at the lower part of the drying chamber 1 and blows warm air from the lower part to the upper part. In the second embodiment, the opening 10 is formed in the drying chamber 1. Opened at the top, the hot air blows down from the top to the bottom. Therefore, in this product, the seaweed 15 dries more easily in the upper part than in the lower part, and the detection temperature of the lower second temperature sensor 22 is lower than the detection temperature of the upper first temperature sensor 21. If there is a difference, it is determined that there is uneven drying.

[0020]

As described above, the present invention provides a drying chamber 1
A first temperature sensor 21 and a second temperature sensor 22 are provided at the upper and lower portions of the laver cage 13 transported on the transport path of the first embodiment, and the temperature difference between the ambient temperatures detected by these temperature sensors 21 and 22 is determined. Since the presence / absence of uneven drying is determined, the presence / absence of uneven drying can be appropriately determined with a simple and low-cost structure. And when drying unevenness occurs,
Immediately detecting this and adjusting the temperature and air volume of the drying chamber 1 prevents the occurrence of uneven drying as much as possible, thereby producing high-quality laver with good yield.
