Description

[Detailed description of the invention] In this invention, seaweed quality detection devices 3, 3 are installed on the main conveyor 2 installed in the machine frame 1, and the sorted seaweed transfer conveyor 4 that intersects with the main conveyor 2 is connected to the main conveyor 2.
The conveyor 4 is installed at a slightly lower level position than the main conveyor 2, and the conveyor 4 is configured to be able to be raised and lowered by signals from the detection devices 3, 3, and the corona is placed at a predetermined interval t above the supply side of the unsorted seaweed 5 of the main conveyor 2. The present invention relates to a defective seaweed sorting device that supports a static electricity removal device 6 by discharge and performs corona discharge from the static electricity removal device 6 toward the main conveyor 2.
As shown in FIGS. 1 and 2, the seaweed quality detection device 3 consists of a light source section 3' in which a plurality of phototransistors are arranged in parallel, and a light receiving section 3'', and is arranged in a direction perpendicular to the moving direction of the main conveyor 2. The main conveyor 2 consists of four conveyors as shown in Fig. 1, and gaps are formed between these conveyors so that the sorting seaweed transfer conveyor 4 can be moved up and down. As shown in FIG. 2, the sorted seaweed transfer conveyor 4 has lifting rollers 7 and 7 on both sides of the intersection with the main conveyor 2, respectively.
7 is arranged. The static electricity eliminator 6 is constructed by arranging a large number of needle-like electrodes on a high voltage cable 8, and the high voltage cable 8 is connected to a high voltage generator (with a built-in high voltage transformer) 9 as shown in FIG. When a high voltage is applied to the high voltage cable 8, corona discharge occurs from the removal device 6 toward the main conveyor 2, producing ions in the air, and the dried unsorted seaweed 5 is continuously transported by the conveyor 2. Also, the static electricity charged on the conveyor 2 can be neutralized and removed. In the figure, reference numeral 10 denotes a support plate for the removal device 6, 11 a phototransistor-based supply interval detection device for the unsorted seaweed 5, 12 a support plate for the detection devices 3, 3, and 13 for the unsorted seaweed. 5 an opening/closing stopper, 14 a sorting seaweed detection device at the front of the stopper 13;
15 is a hopper for storing defective seaweed 5'; 16 is a sprocket provided on the motor shaft; 17 is a drive chain; 18 is a sprocket provided on the drive shaft 19 of the main conveyor 2; 20 is a belt drive roller provided on the same shaft 19; 21 is a driven roller, 22 is a drive belt, 23 is a power cable for the removing device 6, 24 is a switch for the device 6, and 25 is a power outlet for the cable 23.

Therefore, dried unsorted seaweed peeled from the seaweed cage 5
are sequentially fed to the main conveyor 2, the same sorted seaweed 5
moves in the direction of arrow a shown in FIG. 1 and passes under the static electricity eliminator 6. At this time, static electricity charged on the unsorted seaweed 5 and the conveyor 2 can be neutralized and removed. And the above unsorted seaweed 5
When the seaweed further moves and passes between the seaweed quality detection devices 3, 3, tears, holes, etc. are detected by light emitted from the light source section 3' of the detection device 3 during this passage. When no holes or tears are detected, the opening/closing stopper 13 is not opened by the signals from the detection devices 3, 3, and the sorted seaweed transfer conveyor 4 rises to the imaginary line position shown in FIG. ) 5'' in the direction of the arrow b shown in FIG. 3, 3 opens and transfers the defective seaweed 5' into the defective seaweed storage hopper 15. In this way, the unsorted seaweed 5 can be sorted.

When conventionally dried seaweed is peeled from a seaweed cage using an automatic seaweed peeling device, the seaweed is extremely susceptible to static electricity due to the friction generated during peeling, and this causes an inconvenient adhesion phenomenon, making it difficult to sort smoothly. There was a defect that made it difficult to transfer or unload.

Since the present invention is configured as described above, the static electricity charged on the dried unsorted seaweed 5 and the conveyor 2 that are sequentially supplied to the main conveyor 2 can be reliably neutralized and removed by the static electricity removing device 6 using corona discharge. In addition to preventing inconvenient adsorption phenomena, the above-mentioned unsorted seaweed 5
There is a practical benefit in that the selection process can be carried out extremely smoothly and reliably. Further, there is an advantage that transfer and unloading by a conveyor can be carried out smoothly and no conveyor for holding the transfer seaweed is required.
