Next, the configuration of the laver holder, which is a constituent member of the laver manufacturing apparatus, will be described with reference to FIGS. 2 and 3. FIG.

FIG. 2 is a diagram for explaining a laver holder, which is a constituent member of a laver manufacturing apparatus for manufacturing sheet-shaped dried laver ((a) is a plan view, (b) is a side view), and FIG. 2 is an enlarged side view of the laver holder shown in FIG.
2(a) and 3 indicate the direction in which the laver screen holder 3 is conveyed by the conveyer 4L on the lower side in the laver manufacturing apparatus 1. As shown in FIG.

As shown in FIGS. 2 and 3, the laver holder 3 used for papering and drying raw laver includes two parallel first rods 3a, 3a (horizontal rod and rod member). , and a plurality of (three in FIG. 2) seaweed screens 3c stretched and held between the two first rods 3a, 3a via fasteners 3b. In addition, the seaweed screen holder 3 has two second rods 3d, 3d extending parallel to the first rods 3a, 3a outside the first rods 3a, 3a (on the upstream side in the conveying direction). The second rod portion 3d comprises a "horizontal rod"). Two connecting members 3j, 3j (vertical rods) extending perpendicularly to the second rods 3d, 3d are stretched across the second rods 3d, 3d with the three seaweed screens 3c sandwiched therebetween. ing.

Inside the two connecting members 3j, 3j, two support members 3e, 3e are provided in parallel with the two connecting members 3j, 3j with the three seaweed trays 3c sandwiched therebetween.
One end of the support member 3e is fixed to the lower surface of the second rod portion 3d (horizontal rod) on the upstream side in the transport direction, and the other end portion of the support member 3e is fixed to the second rod portion on the downstream side in the transport direction. It is fixed to the top surface of 3d. The first rod portion 3a (bar member) on the upstream side in the conveying direction is positioned on the upper surface of the supporting member 3e, and the first rod portion 3a (horizontal rod) on the downstream side in the conveying direction is positioned on the lower surface of the supporting member 3e. there is
Both ends of the first rod portion 3a (bar member) on the upstream side in the conveying direction are pushed to the upper surface of the second rod portion 3d (horizontal rod) by torsion springs 3i (spring members) attached to the support members 3e, 3e. It is pressed against the fixed stopper 3h from below. Both ends of the first rod portion 3a (horizontal rod) on the downstream side in the conveying direction are fixed to the lower surface of the second rod portion 3d by torsion springs 3i (spring members) attached to the support members 3e, 3e. It is pressed from above against the stopper 3h. As a result, the seaweed screen 3c is fixed at the extended position. The free end of the torsion spring 3i (spring member) protrudes from the seaweed screen holder 3 to the upstream side or the downstream side in the conveying direction.

The laver screen 3c is constructed by arranging a plurality of resin-made rod-like members 3f in parallel and binding them with a thin string 3g. Here, as the rod-shaped members 3f, those having different surface properties such as roughness and fine striped patterns are used on the front and back surfaces, and these rod-shaped members 3f are formed in a form in which the surfaces having the same properties are aligned. Lashing in parallel. The seaweed screen 3c produced in this way has different surface properties on the front side and the back side. , it is possible to select and use a more suitable surface as the papermaking surface.

When the laver holder 3 in the laver manufacturing apparatus 1 is conveyed, the laver holder 3 is conveyed in a state in which both ends of the second rods 3d, 3d are supported from below.

If the laver holder 3 is configured as described above, it is possible to eliminate the front-to-rear orientation of the laver holder and, for example, to use both sides of the laver holder by turning it inside out.

[Structure of seaweed stripping device (main stripping unit)]
Next, the configuration of the laver peeling device (main peeling unit) in one embodiment of the present invention will be described with reference to FIG.

FIG. 4 is a side view showing a part of the laver peeling device according to one embodiment of the present invention.
The "conveyance direction" shown in FIG. 4 indicates the direction in which the laver tray holder 3 is conveyed by the conveyer 4L on the lower stage in the laver manufacturing apparatus 1. As shown in FIG.

As shown in FIG. 4, the laver stripping device (main stripping unit) 15 has a belt 17 provided with a suction surface 17a for sucking the dry laver 16 adhering to the lower surface side of the laver screen 3c, and the dry laver 16 is sucked. By rotating the upper part of the belt 17 in this state in the vertical direction of the paper surface of FIG. A belt elevating means 19 for contacting and separating from the lower surface of 3c, a chuck portion 20 for holding and releasing the first rod portion 3a (bar member) on the upstream side in the conveying direction of the seaweed screen holder 3, and the first rod portion. By moving the chuck part 20 holding the 3a (rod member) along a predetermined trajectory, the dried laver 16 sucked by the suction surface 17a is peeled off from the laver screen 3c in the nori screen holder 3. and a chuck moving means 21 for performing a folding operation.
In addition, reference numeral 18a in FIG. 4 indicates a suction chamber. The suction chamber 18a sucks the dried seaweed 16 on the belt 17 through the through holes 17b of the belt 17. As shown in FIG.

The chuck moving means 21 includes a moving portion 22 having a chuck portion 20 coupled to a lower portion thereof, which is formed on a guide beam 23 via a link mechanism (not shown) driven by a chuck horizontal moving mechanism (not shown). It is configured to move along the guide groove 23a. As a result, the moving portion 22 reciprocates along the guide groove 23a (see arrows A and B in FIG. 4), and the chuck portion 20 reciprocates in the horizontal direction accordingly.
Then, while holding the first rod portion 3a (rod member) on the upstream side in the conveying direction of the seaweed screen holder 3, the chuck portion 20 is moved forward in the horizontal direction (see the arrow in FIG. 4), so that the seaweed is The screen 3c can be made to perform a folding operation. Further, by moving back the chuck part 20 in the horizontal direction as it is after the folding operation (see arrow B in FIG. 4), the seaweed screen 3c can be returned to the stretched position.

At least when the chuck portion 20 is reciprocated (see arrows A and B in FIG. 4), the upper surface of the suction rotation belt 18 and the tip portion of the chuck portion 20 do not interfere with each other. (and the guide groove 23a formed in the guide beam 23) are inclined downward in the return movement direction of the chuck portion 20 (see arrow B in FIG. 4).
However, if this is left as it is, the folding angle when the laver screen 3c in the laver screen holder 3 is made to perform the folding operation gradually widens (it becomes difficult to keep the angle at which the laver screen 3c is pulled at an acute angle), and the dried laver 16 And there is a possibility that the laver screen 3c may become difficult to separate. Also, it becomes difficult to suppress the upward component of the force applied to the dry seaweed 16 to a small value. For this reason, it is not possible to completely prevent the dry seaweed 16 from tearing when it is peeled off.

In order to solve this problem, the present embodiment employs the following configuration.
That is, in the present embodiment, the suction rotating belt 18 is arranged in correspondence with the guide beam 23 in a direction opposite to the direction of movement of the chuck portion 20 when peeling off the dried seaweed 16 (return direction of the chuck portion 20 (Fig. 4). ), the inclination angle α from the horizontal plane is approximately half the inclination angle β of the guide beam 23 from the horizontal plane.

Such a configuration of the laver stripping device (main stripping unit) 15 of the present embodiment has the following effects.
That is, according to this configuration, the tip portion of the chuck portion 20 holding the first rod portion 3a (bar member) on the upstream side in the conveying direction of the seaweed screen holder 3 interferes with the upper surface of the suction rotation belt 18. It is possible to bring it close to the upper surface of the suction rotating belt 18 to the extent that it does not. As a result, when the seaweed screen 3c in the seaweed screen holder 3 is made to perform the folding operation (see arrow A in FIG. 4), the folding angle γ can be kept small (the angle at which the seaweed screen 3c is pulled can be kept at an acute angle). ), and the distance between the dried seaweed 16 and the seaweed screen 3c is improved. Also, the upward component of the force applied to the dry seaweed 16 can be minimized.
Therefore, according to such a configuration, it is possible to more reliably prevent the dry laver 16 from being torn when it is peeled off, and to ensure the quality improvement of the dry laver 16 .

Further details will be described below.
In the structure of the seaweed peeling device 15 of the present embodiment, it is preferable that the inclination angle of the suction rotation belt 18 with respect to the horizontal plane is in the range of more than 0° and 5° or less.
According to such a preferable configuration, when the chuck portion 20 is reciprocatingly moved while holding the first rod portion 3a (bar member) on the upstream side of the conveying direction of the seaweed screen holder 3, the tip portion of the chuck portion 20 is , it is possible to reliably bring it close to the upper surface of the suction rotation belt 18 to the extent that it does not interfere with the upper surface of the suction rotation belt 18 .

Further, in the configuration of the laver peeling device 15 of the present embodiment, it is more preferable that the inclination angle of the suction rotating belt 18 with respect to the horizontal plane is in the range of about 2 to 3 degrees.
According to such a preferable configuration, it is possible to set the inclination angle so that the dry laver 16 is not burdened when the laver screen 3c in the laver screen holder 3 is made to perform the folding operation.

In addition, in the structure of the seaweed peeling device 15 of the present embodiment, it is preferable that the inclination of the suction rotation belt 18 is adjustable.
According to this preferable configuration, it is possible to adjust the inclination angle to the least burden on the dried laver 16 when the laver screen 3c in the laver screen holder 3 is folded back.

In FIG. 4, reference numeral 24 indicates a guide member, and reference numeral 24a indicates a guide member elevating mechanism. By providing such a component, the guide member 24 is lifted by the guide member elevating mechanism 24a in order to fix the position of the laver holder 3 in the conveying direction prior to the lifting of the suction rotation belt 18. The second rod portion 3d (horizontal rod) on the upstream side in the conveying direction of the holder 3 can be guided. That is, the guide member 24 and the guide member elevating mechanism 24a serve as a guide mechanism for fixing the position of the laver screen holder 3 positioned in the main stripping portion 7b (see FIG. 1) in the transport direction.

Further, in FIG. 4, reference numeral 25 indicates a pressing member, and reference numeral 25a indicates a pressing member elevating mechanism. In the final stripping section 7b, a pressing member elevating mechanism 25a is provided above the free end of the torsion spring 3i (spring member) protruding upstream in the conveying direction from the laver holder 3 whose position is fixed by the guide member 24. A pressing member 25 that is vertically driven by is arranged. By lowering the pressing member 25 by the pressing member elevating mechanism 25a, the pressing member 25 presses downward the free end of the torsion spring 3i (spring member) projecting from the laver screen holder 3 to the upstream side in the conveying direction. , the pressing of the first rod portion 3a (bar member) of the seaweed screen holder 3 in the extended position against the stopper 3h (see FIG. 2) can be released.

[Construction of belt]
Next, the specific configuration of the belt, which is a constituent member of the laver peeling device (main peeling unit) in one embodiment of the present invention, will be described with reference to FIG. 5 as well.

FIG. 5 is a plan view showing part of a belt, which is a component of the laver peeling device in one embodiment of the present invention.
5 indicates the direction in which the laver tray holder 3 is conveyed by the conveyer 4L on the lower stage in the laver manufacturing apparatus 1. As shown in FIG. 5 indicates the direction in which the upper portion of the belt 17 rotates.

The belt 17 is an endless belt having an upper stage portion and a lower stage portion.
As shown in FIGS. 4 and 5, a plurality of through-holes 17b with a diameter of about 6 mm are formed in almost the entire surface of the belt 17, and by driving the suction chamber 18a, the through-holes 17b are sucked, The suction surface 17a of the belt 17 is adapted to hold the dry seaweed 16 by suction.

A plurality of through-holes 17b formed in the belt 17 are arranged, for example, as shown in FIG.
That is, the through-holes 17b are arranged in a zigzag pattern in the width direction of the belt 17, and arranged in the longitudinal direction of the belt 17 at regular intervals. The intermediate portion in the width direction of the belt 17 has fewer through-holes 17b per predetermined area (about half) than the front and rear portions in the width direction, except for the central portion.
The density of the through-holes 17b in the front and rear portions in the width direction may be such that the strength of the belt 17 is not lowered.

By configuring the belt 17 as described above, the following effects can be obtained.
That is, the through-holes in the conventional belt are formed with a uniform density over the entire surface (the diameter of the through-holes is about 6 mm, and the density is such that the strength of the belt does not decrease). For this reason, when the dried laver is adsorbed, there is a risk that air will enter between the belt and the dried laver at the intermediate portion of the dried laver, causing the dried laver to break and wrinkle.
On the other hand, according to the structure of the belt 17 of the present embodiment, the number of through holes 17b per predetermined area in the intermediate portion (excluding the central portion) of the belt 17 in the width direction is reduced, so that the intermediate portion of the dried seaweed 16 Since the suction force is reduced at the part and air is less likely to enter between the belt 17 and the dry laver 16, the dry laver 16 can be prevented from being broken and wrinkled.
In addition, according to the structure of the belt 17 of the present embodiment, the number of through holes 17b per predetermined area in the intermediate portion (excluding the central portion) of the belt 17 in the width direction is reduced, so that the front portion of the dried seaweed 16 and the At the rear part, the suction force increases and the adsorption becomes stronger, and the separation between the dried laver 16 and the laver screen 3c when the laver screen 3c is folded back in the nori screen holder 3 is improved (further improvement in stripping ability). .
Therefore, according to the configuration of the belt 17 of the present embodiment, the dry laver 16 is prevented from being wrinkled when stripped, and the stripping ability is further improved to ensure the quality improvement of the dry laver 16. becomes possible.

In this embodiment, the intermediate portion in the width direction of the belt 17 has fewer through-holes 17b per predetermined area than the front and rear portions in the width direction, except for the central portion. A case has been described as an example. However, the present invention is not necessarily limited to such a configuration. At least a part of the intermediate portion in the width direction of the belt 17 should have fewer through-holes per predetermined area than the front and rear portions in the width direction. For example, the entire surface of the intermediate portion in the width direction of the belt 17 may have fewer through-holes 17b per predetermined area than the front and rear portions in the width direction. Further, the intermediate portion in the width direction of the belt 17 may have a structure in which a region with a high density of the through-holes 17b and a region with a low density of the through-holes 17b are alternately present in stripes.
Also, the through holes 17b of the belt 17 may be formed with a uniform density over the entire surface.
