That is, there is nori A which is hard and chewy depending on the amount of water content (dry state) and the thickness (thickness), but on the other hand there is nori A which is soft and stiff. These are caused not only by the fact that the seaweed A is a natural product, but also by the difference in humidity depending on the place of production, the production site, the production year, the climate, the production line or the processing line, and so on.
In many cases, the soft seaweed A is provided, and in that case, the step of sending out to the conveyor section 3 in (5) of FIG. 4 described above is as shown in FIGS. (5′) and (5″). In addition, the trouble point R and the trouble were easy to occur.

That is, when the seaweed A′ which is soft and has no waist cannot be maintained in a flat state when being fed from the suction portion 6 of the feeding mechanism 4 onto the conveyor portion 3, slips, floats, sags and the like are likely to occur at the front end portion and the like. ..
The seaweed A′ in a flat state in which suction and suction were released and which was simply placed on the suction section 6 was not firmly received on the conveyor section 3, did not transfer, and was prone to error.
As described above, in the case of the soft seaweed A, it has been pointed out that the conventional seaweed feeder 1 has a problem in supply stability. In the case of the seaweed A′ having a deformed shape, the defective portion R and trouble are likely to occur in accordance with this, and a problem has been pointed out to the supply stability of the seaweed A′.

The seaweed feeder 8 of the present invention is configured as described above. Then it becomes as follows.
(1) In the feeding mechanism 11 below the stock unit 9, the flat stacked laver (seaweed bundles) A stored in the stock unit 9 is held from below on the pair of left and right holding arms 12 in the holding posture D. (See (1) of FIG. 1).

(2) Then, when the holding arm 12 is displaced downward from the upper holding posture D to the lower opening posture E, the released laver A is in a tilted posture G right below the pair of left and right suction portions (suction fans). It is dropped onto the projecting piece of 13 and the left and right ends are held from below and both sides (see (2) of FIG. 1).

(3) Then, the stacked laver A is directly sucked while the left and right suction portions 13 are elevated and displaced to the upper flat position F while the left and right end portions are contact-held from the lower side and both sides (see FIG. 1). (3) See figure).
In the illustrated example, the suction portion 13 has a flat-faced suction port as the upper surface, and the stacked laver A has a lower one sheet of lower seaweed A′ and the left and right end portions thereof are flat by the suction ports of the left and right suction portions 13. It is directly and indirectly sucked and adsorbed.

(4) Then, the left and right suction parts 13 are displaced downward from the flat posture F to the original lower inclined posture G. Then, the lowermost one piece of lower laver A′ of the stacked laver A that was held, sucked, and adsorbed by the suction portion 13 was pulled from its flat state until the left and right end portions were respectively drawn downward, As a result, it is greatly bent downward (see (4) in FIG. 1).
That is, one sheet of lower laver A′ located at the bottom of the stacked laver A is contacted and adsorbed by the left and right suction portions 13 in the inclined posture G with respect to the flat center portion. As it continues, it is pulled and bends downward greatly.

(5) As a result, between the stack laver A, which is entirely flat, and the bottom laver A', which is sucked and adsorbed by the suction unit 13 and whose left and right ends are greatly downwardly curved, to the left and right A gap S is formed in each.
The left and right holding arms 12 are inserted into and inserted into the gaps S by ascending from the lower open posture E to the original upper hold posture D ((4) of FIG. 1 and FIG. 1) See figure).
Therefore, the holding arm 12 separates the upper layer of laver A from the lower layer of laver A′, and lifts and holds the layer of laver A from the lower side. The remaining lowermost sheet of seaweed A'is continuously sucked and adsorbed by the suction unit 13 from below.

(6) Then, the one piece of the lower laver A′ that is being held, sucked, adsorbed, and bent by the suction unit 13 is directed toward the nip roller 7 from above the suction unit 13 by the forward movement of the extrusion unit 15. Then, it is pushed out and sent out. In the illustrated example, first, the front end portion is extruded and sent to the nip roller 7 (see (2) in FIG. 2).

(7) Then, the lower laver A′ is sequentially bitten between the nip roller 7 and the lower roller 18 which is rotationally driven from the front end portion to the rear end portion, so that the string belt 32 on which the conveyor unit 10 runs. It is handed over to the upper part (see (3) in FIG. 2).

(8) The seaweed feeder 8 follows these operation steps, and one lower seaweed A′ from the stacked seaweed A of the stock unit 9 is sent to the conveyor unit 10 and processed from the conveyor unit 10. Supplied to the line. For example, the foreign matter inspection device 19 of the production line B and the baking device 26 of the processing line C are sequentially turned on (see FIGS. 5A and 5B).

(9) Now, the seaweed feeder 8 employs the sandwiching roller 7 and the extruding means 15 in combination, so that one sheet of the lower seaweed A′ is extruded from the suction part 13 during the suction operation. It is extruded at 15 and sent out, bitten by the nip roller 7, and delivered to the conveyor section 10.
The lower seaweed A′ that is being held, sucked, sucked, and bent by the suction unit 13 is gradually extruded, sent out, bitten, and handed over in the state where the suction is continued.
In this way, the lower seaweed A′ is bitten by the sandwiching roller 7 while being sucked. Therefore, even in the case of the soft and stiff seaweed A'or the shape-deformed seaweed A', slipping, bending, rising, bouncing, sagging, bending, damage, etc. at the time of feeding ((5') figure, (5" in Fig. 4) (See the figure) will be reliably prevented.

(10) In other words, seaweed A is a natural product, and also contains moisture depending on the difference in humidity depending on the place of production, production site, production year, climate, production line B or processing line C, etc. There is some amount (dry state) and wall thickness (thickness), and there is nori seaweed A that is hard and has a waist. On the other hand, there is no seaweed A that is soft and has no waist. Furthermore, there is also seaweed A whose shape is deformed from the flat state.
Even if the seaweed A to be provided is the soft seam-less seaweed A or the seaweed A having a deformed shape, the seaweed A is pushed out from the suction unit 13 onto the conveyor unit 10 without any mistake or trouble, You will be able to transfer and hand over.

(11) Moreover, these are easily realized with a simple configuration by providing the sandwich roller 7 on the inlet side of the conveyor section 10 and the extrusion means 15 on the delivery mechanism 11 in the seaweed feeder 8.

(12) By the way, the seaweed feeder 8 is of course used without delay even when the seaweed A having a firm and chewy texture is provided. As expected, it is sent out by the extrusion means 15 and is caught by the sandwiching roller 7.
The operation and the like of the present invention are as described above.
