Therefore, when the motor 57 rotates forward, the base plate 50 rises and the perforated belt 5 on the box 31 abuts against the lower surface of the seaweed cage 23 (see the chain line in the same figure). The belt 5 moves down and separates from the laver cage 23. Dry laver 24 adheres to the lower surface of laver cage 23. FIG. 2 shows a state where the box 31 is raised.

In FIG. 3, when the laver 23 is transported in the direction of arrow N3, the box 31 is lowered so as not to obstruct the transport, but the laver 23 stops above the box 31. When the laver is peeled off, the box 31 rises and the perforated belt 5 comes into contact with the lower surface of the laver 23. In addition to the nut 55 and the ball screw 56, a crank mechanism is often used as a mechanism for vertically moving the box 31 and the porous belt 5.

In FIG. 2, a box 31 includes a first holding section 61 and a second holding section 61 which constitute a holding mechanism 60 for the laver cage 23.
And a third pressing portion 63 are provided. The first presser 61 presses the central portion of the laver 23 onto the upper surface of the box 31 when peeling the dried laver 24 from the laver 23. The second holding part 62 and the third holding part 63 are located on both sides of the first holding part 61 and hold the laver cage 23. The first to third holding parts 61, 62, 63 are formed of an elastic material such as rubber.

FIGS. 4, 5, 6 and 7 show a state in which the holding mechanism 60 of the laver is composed of first to third holding parts 61, 62, 63 and the like, and is mounted on the lower surface of the laver 23. The step of stripping the dried seaweed 24 is shown in the order of steps. In FIG. 4, the first holding portion 61 is attached to the lower end of the first shaft 64, and is resiliently pushed by a coil spring 65 attached to the first shaft 64. The second holding part 62 is attached to the lower end of the second shaft 66 and

Has been bombarded by FIG. 4 shows an initial state. In this state, the center first pressing portion 61 is positioned so as to be lower than the second and third pressing portions 62 and 63 on both sides. ing.

In FIGS. 4 and 8, reference numeral 70 denotes a fixed frame.
A square pipe 71 as a holding member for the shafts 64, 65, 66 is horizontally disposed, and the first to third shafts 64, 66, 68 are vertically inserted into the square pipe 71. . A shaft 72 is attached to the side surface of the square pipe 71, and one end of a lever 73 is mounted on the shaft 72. The other end of the lever 73 has a rod 74
Is axially mounted. When the rod 74 and the lever 73 swing by being driven by a motor and a cam (not shown), the square pipe 71 and the first to the first pipes held by the square pipe 71 are rotated.
The third holding portions 61 to 63 perform up and down operations. That is, the lever 73, the rod 74, etc.
Up to 63 means. Note that such an up-and-down means is a well-known mechanism in a laver peeling apparatus, and therefore FIG. 8 is simply shown.

This laver peeling apparatus has the above-described configuration, and its operation will be described below. As shown in FIG. 3, when the laver 23 stops above the box 31, the motor 5
The box 31 and the perforated belt 5 where the 7 rotates forward rise,
The perforated belt 5 contacts the lower surface of the laver 23,
The inside of the box 31 is vacuum-suctioned by the suction force of the suction unit 36, and the laver 23 is vacuum-sucked on the upper surface of the porous belt 5.

On the other hand, the first to third pressing portions 61 to 63 are
Initially, they are all in the upper position as shown in FIG. Now,
When the laver 23 is vacuum-adsorbed and fixed to the upper surface of the perforated belt 5 as described above, the square pipe 71 descends, and the first holding portion 61 first lands on the laver 23, and then the figure As shown in FIG. 5, all the holding portions 61 to 63 are
And presses the laver 23 against the upper surface of the perforated belt 5.

The rotation of the cam 17 (FIG. 2) causes the roller 11 to move downward, and the laver cage 23
, The laver cage 23 is pulled laterally. Then, both ends of the dried laver 24 are peeled off from the lower surface of the laver 23. Peeling off both ends of the dried laver 24 from the laver cage 23 in this manner is generally called ear stripping.

Next, the square pipe 71 rises slightly. Then, as shown in FIG. 6, the first holding portion 61 located at the central low position
Only the ladle 23 is kept pressed against the perforated belt 5, and the second and third holding parts 62, 63 on both sides are lifted away from the laver 23. Then, by operating the roller 11 to the side again and pulling the laver 23 to the side,
The middle part of the dried laver 24 is peeled off from the laver cage 23.

Next, when the square pipe 71 is further raised, all the holding portions 61 to 63 are separated from the laver cage 23 as shown in FIG. Then, by operating the roller 11 to the side again and pulling the laver 23 sideways, the central part of the dried laver 24 is peeled off from the laver 23. When the square pipe 71 is further raised, it returns to the initial state shown in FIG. 4, and the peeling operation ends.

As described above, this seaweed stripping apparatus first strips both ends of the dried seaweed 24 and then strips the middle part.
Finally, peel the dried seaweed 24 from the seaweed cage 2 by peeling off the central part.
The dried laver 24 can be reliably peeled off from the laver cage 23 by completely peeling off the dried laver 24 from the laver cage 23. Moreover, the coil springs 65,
First to third holding portions 61 to 63 repelled by 67 and 69
By setting only the first holding portion 61 to the low position, the holding at the time of peeling the seaweed, which is performed in the third stage, can be performed while easily switching by the raising operation of the square pipe 71. .

When the peeling operation is completed as described above, the roller 11 moves up and separates from the laver 23,
The motor 57 rotates in the reverse direction, the box 31 and the perforated belt 5 descend, and the perforated belt 5 rotates in the direction of the arrow N1.
Then, it is carried out onto the conveyor 26 through the space between the rollers 25 (see arrow N4 in FIG. 2). When a series of operations is completed in this way, the laver holder is transported in the direction of arrow 3 to the next step.

By the way, the sea laver 23 is transported in the drying chamber and heated, so that it is thermally deformed and bent upward. On the other hand, since the upper surface 32 of the box 31 is also curved in the shape of an upward convex portion, the seaweed cage 23 does not deform unnaturally when the seaweed is peeled off as shown in FIG.
Vacuum suction is performed along the upper surface 32 while maintaining the upward convex curved shape.
No shrinkage or cracking occurs in No. 4 and the seaweed can be peeled off without difficulty. The present invention is not limited to the above-described embodiment. For example, a fourth pressing portion and a fifth pressing portion may be further provided on both sides of the second pressing portion 62 and the third pressing portion 63. It is only necessary that at least three holding portions be provided.

[0030]

As described above, according to the present invention, dry laver adhering to a laver cage can be reliably removed in a plurality of stages. In addition, since the upper surface of the box for vacuum suction of the laver is curved upwardly convex in the transport direction N3 of the laver, the laver does not deform unreasonably.
Vacuum absorption is performed along the upper surface while maintaining the curved shape of the upward convexity, so that the dried laver does not shrink or crack, and the laver can be easily peeled off.
