Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a device for removing the core from wakame seaweed.

《Conventional technology》In the conventional wakame coring machine,
In order to prevent wakame seaweed from meandering, grooves are provided in the lower roller (for example, Japanese Utility Model Application Publication No. 115092/1983).

<<Problems to be solved by the invention>> However, simply adding grooves to the roller cannot accommodate wakame cores of various thicknesses. That is, if the core is too thick compared to the groove, the force that pinches the core becomes excessive and the core is likely to break. On the other hand, if it is too thin, the leaves will remain in the core.

This invention aims to eliminate such problems in wakame coring machines.

《Means for solving the problem》The wakame corer of this invention rotates while holding the core of wakame,
It is equipped with two upper rollers that send the core upward, and two lower rollers that are parallel to these and rotate in the opposite direction to the upper rollers with the wakame in between to peel the leaves from the core. The lower roller consists of a roller body and a rubber layer covering its surface, and is characterized in that the roller body is provided with circumferential grooves, and a gap is formed between the bottom of the groove and the rubber layer. .

[Operation] The wakame core fits into the groove together with the rubber layer and does not swing from side to side. In addition, the rubber layer can be recessed as much as you want until it hits the bottom of the groove, so even if the core is thick, the force with which the rollers pinch the core will not become excessive.
Furthermore, regardless of the thickness of the core, almost the entire surface of the wakame is in close contact with the rubber layer.

<<Example>> As shown in FIGS. 1 and 2, this machine has a pair of upper and lower rollers, namely, an upper fixed roller 1a, an upper moving roller 2a, a lower fixed roller 1b, and a lower moving roller 2b. There is. The surface of each roller is covered with a layer of rubber.
Furthermore, there are fine grooves on the surface to prevent slipping. As shown in FIG. 6, the lower rollers 1b and 2b are provided with a circumferential groove 24 approximately at the center of the roller body C, and a gap 25 is formed between the bottom of the groove and the rubber layer D. . Returning to FIGS. 1 and 2, reference numeral 3 denotes a shaft that connects each roller to a motor (not shown) for driving the roller, and a flexible shaft is used for the moving roller.
Note that there is one drive motor for the upper roller and one drive motor for the lower roller.

The upper and lower fixed rollers 1a and 1b are rotatably supported between the front surface of the machine box 4 and a plate 6 fixed thereto by a rod 5.

The vertically moving rollers 2a, 2b have sleeves 7a,
These sleeves are supported rotatably and cantilevered by plate members 9a, 9b on shafts 8a, 8b rotatably supported in the machine box 4.
are connected via. From the shafts 8a and 8b,
Lever 10a, 10b is extended, and when these levers are rotated, moving rollers 2a, 2b are moved to shaft 8.
It moves around a and 8b, and approaches and moves away from fixed rollers 1a and 1b. Reference numerals 11a and 11b indicate levers 10a and 10 so that the moving rollers 2a and 2b approach the fixed rollers 1a and 1b.
A tensioning spring pulling 0b, reference numeral 12a,
12b is a stopper that comes into contact with the lever when the moving roller approaches the fixed roller.

Another shaft 13 is supported within the machine box 4, and this shaft is rotationally driven by a low speed motor 14. Reference numeral 15 is a transmission chain, and 16 and 17 are sprockets. This shaft 13 has two protrusions 18.
a and 18b are protruding, and when the shaft rotates, the tip of the protrusion rotates while slidingly contacting the lever, and the spring 11 expands and contracts accordingly, causing the lever 10 to rotate.

The reference numeral 19 is a limit switch that operates according to the rotation angle of the shaft 13, and the reference numeral 20 is a micro switch mounted on the roller.

Next, the operation of this machine will be explained. First, protrusion 1
8a, 18b resist the force of springs 11a, 11b as shown by chain lines in FIG.
10b is pushed, so there is a gap between the movable roller 2 and the fixed roller 1. Insert the seaweed from the side into this gap.

In this machine, the fixed roller 1 is longer than the movable roller 2, and the wakame seaweed can be inserted between the rollers using the tip of the fixed roller 1 as a guide, as shown by the arrow in Figure 1. Therefore, even if the gap between the rollers is small, the wakame seaweed can be inserted easily.

When the wakame is placed between the rollers and touches the micro switch 20, one of the roller drive motors starts and the lower rollers 1b and 2b rotate, and at the same time, the low speed motor 14 starts and the shaft 13 rotates. Rotate counterclockwise in figure 2. Then, protrusion 1
8 changes, the levers 10a, 10b are pulled together by the force of the spring 11, the upper shaft 8a rotates counterclockwise, the lower shaft 8b rotates clockwise, and the movable rollers 2a, 2b rotate against the fixed rollers 1a, 10b. Gradually approaches 1b. The state of Laura at this time is the third
Shown in Figure A.

Eventually, the upper moving roller 2a approaches the upper fixed roller 1a, and the core 22 of the wakame 21 is sandwiched between the two rollers. In order to prevent the upper roller from pinching the wakame leaves 23, the leaves 23 are cut off from the core 22 only at the ends in advance, as shown in FIG. The lower moving roller 2b has upper and lower levers 10a and 10b of different lengths, and is adapted to approach the lower moving roller 2b more slowly than the upper moving roller 2a. Therefore, when the lower rollers 1b, 2b approach each other after the upper rollers 1a, 1b finish sandwiching the wakame core, the wakame leaf 22 between the upper and lower rollers
A is peeled off by the lower rollers 1b and 2b.
The situation at this time is shown in FIG. 3B.

Eventually, the lower moving roller 2b moves to the lower fixed roller 1b until the lever 10b hits the stopper 12b.
, the limit switch 19 is activated, the low-speed motor 14 is stopped and the rotation of the shaft 13 is stopped, and the other roller drive motor is also started and the upper roller 1
a and 2a start rotating. This situation is shown in FIG. 3C, where the seaweed core 22 is
The leaves 23 are sandwiched between the rollers 1b and 2a and sent upward, and the leaves 23 are plucked from the core 22 by the lower rollers 1b and 2b. At this time, as shown in FIG. 6, the core 22 fits into the groove 24 of the lower roller together with the rubber layer D.
It doesn't swing from side to side. Furthermore, since a gap 25 is formed between the bottom of the groove 24 and the rubber layer D,
The rubber layer D can be recessed until it hits the bottom of the groove 24, so that even if the core is thick, the force that pinches the core will not become excessive.
Therefore, the core is difficult to break. In addition, the rubber layer adheres well to the area around the border between the core and leaves of the wakame, so all leaves can be removed.

Once the core and leaves have been separated in this way, the timer operates, the roller drive motor stops, and all rollers stop, and at the same time, the low-speed motor 14 starts rotating in the opposite direction, as shown in Figure 3D. As shown in FIG. 2, the moving rollers 2a, 2b are separated from the fixed rollers 1a, 1b. In this way, the limit switch 19 is activated, the low-speed motor 14 is stopped, and the system is ready to receive the next wakame.

<<Effect>> As explained above, according to this invention, the wakame core fits into the groove of the lower roller together with the rubber layer and does not swing from side to side, so it does not come off from the roller or break. In addition, a gap is formed between the bottom of the groove and the rubber layer, and the rubber layer can be recessed until it hits the bottom of the groove, so even if a thick core comes, the force that pinches the core will not become excessive, and the core will Hard to cut. In addition, since the rubber layer of wakame sticks well to the area near the border between the core and the leaves, it is effective in making it possible to remove all the leaves from the core.
