Description

[Detailed Description of the Invention] The present invention relates to a fastener for attaching a screen to a screen holder used in a seaweed production device.

Dried seaweed is produced by dissolving finely cut seaweed in water, scooping it into a cage, dehydrating it, and then peeling it from the cage.The quality of the seaweed tends to change seasonally, and Depending on changes, it will be necessary to replace the screen.

However, in the conventional method of attaching a screen to a holder, methods such as attaching a hook-shaped metal fitting to the holder and anchoring the screen to this metal fitting were adopted, which required an extremely large amount of labor and time to replace the screen. In short, during this time, the quality of seaweed collected from the ocean deteriorated, and the quality of dried seaweed also deteriorated, resulting in a loss of commercial value.

Incidentally, the number of cages used in one nori production device is several thousand or more.

Furthermore, the finish of dried nori is greatly influenced by how it is stretched on the holder of the screen.

That is, if the screen is attached to the holder under tension, the seaweed spread on the screen will shrink as drying progresses, causing the seaweed to tear.

Further, in order to prevent the seaweed from tearing, if the screen is attached to the holder in a relaxed state, the seaweed will shrink.

Therefore, the tensioning condition of the cage is extremely important for the finish of dried nori, and ideally the cage should be tensioned in the early stages of papermaking, dehydration, and drying, and as the drying shrinkage increases, it will become relaxed. It is desirable to install the

Therefore, the present invention has been devised for the purpose of providing a new stopper for a seaweed cage that allows the cage to be replaced easily and quickly, and allows the cage to relax as the seaweed shrinks as it dries.

Hereinafter, embodiments will be explained along with the drawings.

FIG. 1 is a plan view of the stopper in its engaged state, FIG. 2 is a side view of the same, FIG. 3 is a plan view of the stopper in its expanded state, and FIG. 4 is a side view of the same.

This fastener 1 mainly consists of an upper plate 2 and a lower plate 3, and the ends of the drawing plates are connected with pins 4 so as to be openable and closable.

The drawing board consists of a base 2□, 3□, an outwardly curved abdomen 2°, 3□, and a tongue 23.33 at the tip.

A stop plate 5 is provided protruding from the tongue portion 23 of the upper plate 2, and a hook portion 5' is formed at the tip thereof.

Further, the tongue portion 33 of the lower plate 3 has a long hole 6 corresponding to the hook portion 5'.
is formed, and when the drawing board is closed, the stop plate 5 is fitted into the elongated hole 6 and locked by the hook portion 5'.

As clearly shown in Figure 2, when the drawing board is closed, the abdomen 2 of the drawing board
A certain space 7 is secured by □ and 3□.

In addition, the base 21.2□ of the drawing board has grooves 2' and 3', respectively.
is formed, and a coil spring 8 is installed in the groove 3'.

This coil spring 8 extends to the middle of the space 7, and expands and contracts as appropriate as the screen expands and contracts, as will be described later.

FIG. 5 is a plan view in use, and FIG. 6 is a side view of the same essential parts. In fact, two screens M are attached.

The main stop 1 is attached to one of the horizontal bars 10,
Another stop 12 is attached to the other lateral rod 10°.

7 and 8 are a plan view and a side view of the stopper 12. FIG.

This stopper consists of a substantially arc-shaped base 13 and upper and lower tongue pieces 14□, 142 that protrude from the base 13. The tongue piece 14□ has a stopper piece 15, and the tongue piece 14□ has a stopper piece 15. A hole 16 for securing the piece 15 is formed.

In addition, when in use, the horizontal rod 102 is inserted into the base 13 so as to be held therein, and is engaged with the holder.

This stopper 13 is made of an elastic material such as synthetic resin, and normally both tongues are expanded as shown by solid lines in Figure 8, but when in use, the ends of the screen M are opened. When closed against elasticity, the retaining piece 15 passes through the space between the front rods forming the screen M and is engaged with the hole 16 to hold the screen M.

Next, we will explain the handling.

First, one end of the screen is attached to the horizontal rod 102 using the fastener 12 in the manner described above.

Next, the main stopper 1 is passed through the horizontal rod 10, the horizontal rod 10 is pressed against the coil spring, the other end of the screen is held between the tongues, and both tongues are closed with fingers.

Then, the stop plate passes through between the front rods and enters the long hole.
The hook portion is engaged with the elongated hole (see Fig. 6A).

In this case, it is desirable that the screen be stretched on the holder in a slightly taut state (that is, in a relatively taut state).

Now, in the early stages of papermaking, dehydration, and drying, the stopper 1 is the 6th
As shown by the solid line in the diagram, as the drying shrinkage of the nori becomes more intense, the cage on which the nori is spread also begins to shrink.

Here, if the shrinkage of the screen is not allowed, the seaweed will tear as described above.

However, with this fastener, if the screen does not contract, the main stop also moves in the direction of contraction while compressing the coil spring (see the chain line in Figure 6), so the screen can also contract as the seaweed contracts. Therefore, the seaweed will not tear.

Next, when the drying process is completed and the nori is peeled off from the screen, the tension on the screen will be relaxed, but then the stopper will be biased by the coil spring and return to the solid line position, and the screen will return to a slightly tensioned state again. becomes.

Now, when it becomes necessary to replace the screen due to a change in the quality of the seaweed, as shown in Figure 6, by scraping up the tip of the tongue piece with your fingertips, the stop plate can be easily removed from the long hole, and the screen can be replaced with a holder. It will be removed from the

Incidentally, for the stopper 12, it is only necessary to raise the tongue piece in the same manner.

As explained above, with this fastener, the cage can be replaced easily and quickly, but the quality of the fresh seaweed will not deteriorate significantly during the replacement process.

In addition, even if the screen is stretched under relatively tension, the screen is allowed to shrink as the seaweed dries, making it possible to produce dried nori with a good finish without tearing the seaweed. It can be done.
