The laver suction device 12 rises every time the laver storage pocket 7 of the laver conveying disc 4 intermittently rotates and stops, sucks the laver 2 at the lowest position in the laver stacker 11, and descends. is stored in the seaweed storage pocket 7.

Two seaweed stoppers 13 and 14 are provided at upper and lower positions on one side of the seaweed stacker 11 . The upper laver stopper 13 and the lower laver stopper 14 are each formed in the shape of a flat spatula with a plurality of lines (two lines in this embodiment). It is provided so as to be insertable (forward and backward) between laver 2.

In addition, the lower laver stopper 14 can be moved up and down by the operation of an elevating air cylinder 20, and after being inserted between the loaded laver 2, the upper laver 2 can be lifted and supported by a predetermined amount.

Next, the operation of the laver feeder 3 will be described.

First, as shown in FIG. 2, seaweed is fed into the seaweed stacker 11 and stacked.

Then, as shown in FIG. 6, the lower seaweed stopper 14 is inserted forward between the seaweed 2 and stopped, and then raised by a predetermined amount. As a result, the seaweed 2 in the seaweed stacker 11 is divided into an upper seaweed group a supported by the lower seaweed stopper 14 and a lower seaweed group b supported by the pair of seaweed holders 16, 16 below the lower seaweed stopper 14. separated into As a result, the load on the seaweed 2 at the lowest position is reduced.

Next, as shown in FIG. 7, the seaweed suction device 12 extracts the seaweed 2 at the lowest position among the seaweed 2 stacked in the seaweed stacker 11 (in this embodiment, the seaweed at the lowest position in the lower seaweed group b). 2) rises to a position where it contacts. The suction by the laver suction device 12 is started before this contact, at the same time as the contact, or after the contact. As a result, the seaweed sucking device 12 is in a state of sucking the central portion in the width direction of the seaweed 2 at the lowest position.

Next, as shown in FIG. 8, the seaweed sucking device 12 sucks the widthwise central portion of the seaweed 2 at the lowest position and bends the seaweed 2 at the lowest position so as to protrude downward. to descend.

In the process of lowering the seaweed suction device 12, the seaweed supply device 3 moves the pair of long sides of the bottom seaweed 2 inside the pair of seaweed holding portions 16, 16 to the pair of guide rollers 17, 17. It is configured to receive at

As a result, it is possible to suitably form a state in which the seaweed 2 at the lowest position is curved so as to protrude downward. Due to this curvature, a gap is formed between the laver 2 at the lowest position and the laver 2 superimposed on the nori 2 at the lowest position, and the laver 2 superimposed on the nori 2 at the lowest position is formed. It is prevented that the suction by the laver suction device 12 acts on. Thereby, it is possible to prevent two or more sheets of laver 2 from being taken out at the same time. Thereby, the seaweed 2 can be reliably supplied one by one.

Further, since the pair of guide rollers 17, 17 are rotatable, when the seaweed 2 is drawn downward from between the pair of guide rollers 17, 17, the guide rollers 17, 17 follow the drawing of the seaweed 2. can rotate. As a result, the seaweed 2 and the guide roller 17 are prevented from rubbing against each other, and damage to the seaweed 2 can be prevented.

As shown in FIG. 8, while the pair of long sides of the lowermost laver 2 are in contact with the pair of laver holders 16, 16, the pair of A pair of guide rollers 17, 17 may be configured to receive the long sides. That is, in the process of lowering the seaweed suction device 12, a state is formed in which the seaweed 2 sucked by the seaweed suction device 12 contacts all of the pair of seaweed holding portions 16, 16 and the pair of guide rollers 17, 17. may

Then, as shown in FIG. 9, the laver suction device 12 is further lowered to return to the position shown in FIG. In the course of this further descent, the laver suction device 12 stops sucking and the laver 2 is accommodated in the laver storage pocket 7 of the laver conveying disk 4 . More specifically, the seaweed 2 is placed on the seaweed support portion 21 of the seaweed storage pocket 7 .

By repeating the above operation, the seaweed 2 can be supplied one by one to the seaweed storage pockets 7 sequentially arranged under the seaweed stacker 11 .

By the way, by repeating the above operation, as shown in FIG. 10, the laver 2 in the lower laver group b in the laver stacker 11 gradually decreases. Then, when a detector (not shown) detects that the weight of the laver 2 in the lower laver group b has decreased to a preset weight, the upper laver stopper 13 moves forward as shown in FIG. It is inserted between the seaweed 2 of the upper seaweed group a supported by the lower seaweed stopper 14. - 特許庁As a result, the upper laver group a is divided into an upper laver group a' and a lower laver group b'.

Then, as shown in FIG. 12, the lower seaweed stopper 14 descends by a predetermined amount and then retreats. As a result, the lower laver group b' is dropped onto the remaining lower laver group b for replenishment.

Next, as shown in FIG. 13, the lower laver stopper 14 is inserted forwardly between the laver 2 of the laver group consisting of the lower laver group b' and the lower laver group b, and then rises by a predetermined amount.

Next, as shown in FIG. 14, the upper laver stopper 13 is retracted, and the upper laver group a' supported by the upper laver stopper 13 is dropped onto the laver supported by the lower laver stopper 14. In this way, an upper laver group a and a lower laver group b are formed, and the operations shown in FIGS. 6 to 9 are repeated again.

As described above, by using the seaweed stopper 13, the weight of the seaweed 2 held by the pair of seaweed holding portions 16 is always held at a predetermined amount or less, and the seaweed suction device 12 can take out the seaweed 2. It can be carried out. As a result, the laver 2 piled up on the laver 2 at the lowest position can reduce the force with which the laver 2 at the lowest position is pressed against the pair of laver holders 16, so that the laver can be more reliably secured. 2 can be taken out one by one, and damage to the seaweed 2 is further prevented.

The method of replenishing new seaweed 2 into the seaweed stacker 11 is not particularly limited, and may be performed automatically by a device or manually by an operator.

In the above description, the case where the laver feeding device 3 includes the laver stoppers 13 and 14 has been mainly described, but the present invention is not limited to this, and the laver stoppers 13 and 14 may be omitted as appropriate.

The laver-rolling mechanism of the rice ball laver-rolling device is not limited to the above-described embodiment, and may be configured to roll the laver 2 supplied from the laver supply device 3 around the rice ball 1. A known laver-rolling mechanism may be used. be prepared.
