Description

  The present invention relates to a seaweed stalk separation jig, and more particularly to a jig that can accurately separate leaves from stems regardless of the thickness of the stem.

  When seaweed is cut from the seabed, it may be shipped to the market as it is, but in many cases, the seaweed is separated into stems and leaves, and the leaves are salted and shipped to the market.

  Conventionally, when separating the seaweed stems and leaves, the seaweed was spread on a mortar board, etc., and the stems and leaves were manually separated using a knife or the like, but the work was complicated. It was.

  Therefore, an automatic stalking device for wakame that holds the leaves and stems by respective rollers, and rotates the rollers to pull the stems from the leaves or peel the leaves from the stems (Patent Document 1, Patent Document 2, Patent Document 3). Wakame is transferred by a transfer roller, and the interval between the two cutting blades is adjusted according to the thickness of the stem, and the wakame automatic stem is separated from the stem by the two cutting blades. A dividing device (Patent Document 4) or an automatic stalking device (Patent Document 5) in which a stem is separated by rubbing between a stem and a leaf with a rubber cutting blade has been proposed.

  However, in the stalking apparatus described in Patent Documents 1 to 3, since the two pairs of rollers are moved relative to each other in the opposite direction or the stem is pulled out of the leaf by the roller, the stem and the leaf are separated. Sometimes left on the stem.

  Further, in the stem dividing devices described in Patent Documents 4 and 5, it is complicated to adjust the interval between the cutting blade and the cutting blade according to the thickness of the stem, and the thickness of the stem gradually decreases from the root toward the tip. In some cases, the leaves may remain on the stem or part of the stem may remain on the leaves.

  In view of such problems, an object of the present invention is to provide a wakame stalk separation jig that can accurately separate leaves from stems regardless of the thickness of the stems.

  Therefore, the seaweed stalking jig according to the present invention is a seaweed stalk separating jig used to separate the seaweed stalk and the leaves, opposed to each other, and the tip portion of the stem after separation of the leaves A slidable contact guide portion that can hold the side surface portion and come into contact with the side surface portion is formed, and a cutting blade that cuts between the seaweed stalk and the leaf is formed at one end edge in the vertical direction of the slidable contact guide portion. The first and second arm portions, the spring portions that urge the first and second arm portions in a direction in which the sliding contact guide portions are separated from each other, and the first and second arm portions. A positioning guide portion that guides the approach and separation of the sliding contact guide portion to oppose the cutting blades of the first and second arm portions, and the first and second arm portions include the spring portion. An urging force is applied in a direction against the urging force, and a wakame stalk is sandwiched between the sliding contact guide portions. By being cut out, the cutting blade can cut between the stem and the leaf while the interval between the cutting blades of the first and second arm portions changes according to the thickness of the stem. It is characterized by being.

  One of the features of the present invention is that the first and second arm portions are urged against the urging force of the spring portion to sandwich a seaweed stalk between the slidable contact guide portions, and this stalk is connected to the slidable contact guide portion. With respect to the point which cut | disconnects between a stem and a leaf with a cutting blade, changing the space | interval of the cutting blade of a 1st, 2nd arm part according to the thickness of a stem by pulling out relatively with respect to is there.

  As a result, even if the thickness of the seaweed stalk changes, the distance between the sliding contact guides changes accordingly, and the cutting edge is always positioned accurately between the stalk and the leaf. Leaves can be accurately separated.

  In addition, the sliding contact guides are biased toward each other and slidably contact the side of the stem after leaf separation. Can be separated.

  The first and second arm portions and the spring portion may be formed as separate members and may be linked to each other. However, in consideration of the manufacturing process, one spring band plate is folded into a U shape and It is preferable that the sliding contact guide portions be bent at both tip portions.

  Further, the positioning guide portion is configured separately from the first and second arm portions, and is arranged in front of the sliding contact guide portion of the first and second arm portions, and the first and second arm portions are arranged. The positioning guide portion may be moved back and forth, or may be configured separately from the first and second arm portions and slidably inserted through insertion holes formed in the first and second arm portions. You may make it, and you may form integrally with the 1st or 2nd arm part.

  That is, when the positioning guide portion is formed integrally with the first or second arm portion, the positioning guide portion is formed continuously at the tip of the sliding contact guide portion of the first or second arm portion, A positioning guide receiving portion that receives the positioning guide portion when the sliding contact guide portions of the first and second arm portions approach is formed continuously at the tip of the sliding contact guide portion of the second or first arm portion. It is good to do.

  The sliding contact guide portion may have any shape as long as the sliding contact guide portion can be in sliding contact with the side surface portion of the stem after separating the leaves, but a stable sliding contact can be obtained with a wider contact area. Therefore, it is preferable that the sliding contact guide portion has a concave shape in which the side portion of the stem fits completely or partially.

  The wakame stalk is pinched by the sliding contact guide part, but if it is separated from between the sliding contact guide parts for some reason, the stem and the leaf may not be separated. Therefore, it is preferable to further include a stem positioning portion that positions the stem between the sliding contact guide portions.

  The seaweed stalking jig according to the present invention may be used as a manual tool (seaweed stalking tool), and is set in an automatic device (automatic stalking device) as a tool for separating between a stem and a leaf. It can also be used.

  That is, the first and second arm portions are picked between at least the thumb and the index finger of one hand, whereby a stem separation tool for manually separating the seaweed stem from the leaf can be configured.

  Further, a spring member that applies a biasing force to the first and second arm portions in a direction against the biasing force of the spring portion, and a pulling means that pulls out the wakame stalk sandwiched between the sliding contact guide portions are further provided. An automatic stalking device can also be configured. In this case, when the positioning guide portion is configured separately from the first or second arm portion and the first and second arm portions are moved forward and backward with respect to the positioning guide portion, separation of the seaweed stem and leaves is achieved. Work becomes even easier.
