Description

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

<<Prior Art>> A conventional wakame corer has two upper rollers and two lower rollers that rotate with the wakame in between. Initially, the upper and lower rollers rotate in the same direction, and the wakame core inserted from below is sandwiched between the upper rollers and sent to the upper roller. When the tip of the core is caught between the upper rollers, the lower rollers rotate in the opposite direction, and the lower rollers pinch the wakame leaves and pluck them from the core, which is fed upward by the upper rollers.

《Problems that the invention aims to solve》 As described above, in the conventional centering machine, the wakame is inserted from below between the rotating lower rollers, which poses the risk of hands getting caught, and reduces work efficiency. The problem is that it doesn't go up.

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

《Means for solving the problem》 The wakame corer of this invention has two upper rollers that rotate while sandwiching the wakame core and feed the core upwards, and two upper rollers that are parallel to the upper rollers and rotate to sandwich the wakame core. Pinch and rotate in the opposite direction to the upper roller to pluck the leaves from the core 2
It is equipped with the lower rollers of the book as before, but the feature is that one of the upper rollers and one of the lower rollers move in parallel so that the wakame seaweed can be fed between the rollers from the side.

[Operation] One upper roller and one lower roller move in parallel, so widen the space between the upper and lower rollers, feed the wakame from the side between the rollers, and narrow the space between the rollers to sandwich the wakame. be able to.

<<Example>> As shown in FIGS. 1 and 2, this machine has a pair of upper and lower rollers, namely, an upper fixed roller 1a,
It has an upper moving roller 2a, a lower fixed roller 1b, and a lower moving roller 2b. The surface of each roller is covered with rubber, and the surface is further provided with fine anti-slip grooves in the axial direction. code 3
is a shaft that connects each roller and a motor (not shown) that drives it, and a flexible shaft is used for the moving roller. In addition, there is one drive motor for the upper roller and one for the lower roller.
There is a stand.

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 seaweed 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 torn off from the core 22 only at the ends, as shown in FIG. 4. The lower moving roller 2b has upper and lower levers 10a and 10b of different lengths, and is designed to approach the lower moving roller 2b more slowly than the upper moving roller 2a. Therefore, when the lower rollers 1b and 2b approach each other after the upper rollers 1a and 1b have finished 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, when the lower moving roller 2b approaches 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, the rotation of the shaft 13 is stopped, and the other roller drive motor is also started. and the upper roller 1a,
2a begins to rotate. This situation is shown in FIG. 3C, where the core 22 of the wakame seaweed is
The leaves 23 are sandwiched between the cores 2a and sent upward, and the leaves 23 are plucked from the core 22 by the lower rollers 1b and 2b and hang down. When the wakame core 22 finishes passing through the roller,
Leaf 23 falls to the bottom.

When the core and leaf 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 3. As shown in D, 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, one upper roller and one lower roller move in parallel, so wakame seaweed can be fed between the rollers from the side instead of from below. , there is no risk of getting your hands caught in the rollers, and work efficiency is high.

Also, as shown in the example, if the lengths of the two upper rollers and the two lower rollers are different from each other, the longer roller will act as a guide.
This has the effect of making it easier to put the seaweed between the rollers.
