Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a laver cutting machine or a thin laver cutting machine for chopping raw seaweed such as raw seaweed or rough seaweed raw seaweed into mince form. The present invention relates to a device for reversing a swing member for delivering raw seaweed, which is provided in a seaweed machine such as a seaweed blender that mixes cut raw seaweed and water.

(Prior Art) Previously, the applicant of the present invention used minced shredded raw seaweed such as raw seaweed, which was picked and collected and washed with seawater, and raw seaweed, which was roughly cut and stored. 56-49354
JP, JP-B-56-49355, JP, JP-B-56-
In order to put into practical use a so-called laver cutting machine for feeding and cutting nori seaweed having the structure shown in Japanese Patent No. 50793, etc., and to mix shredded raw seaweed and water, Japanese Patent Publication No. 57-52031.
Japanese Patent Publication No. 58-10066, Japanese Patent Publication No. 59-2265
The so-called seaweed blender, which is a blending and manufacturing apparatus for seaweed-making raw materials having the structure shown in Japanese Patent Publication, has been put into practical use, and each has been well received. Among them, in the case of the former seaweed cutting machine, at the bottom of the seaweed tank, a hollow shaftless screw conveyor that horizontally transfers raw seaweed toward the feed port of the seaweed tank is rotatably supported, and the screw conveyor concerned A pair of swing members (referred to as swing arms in the above-mentioned prior art) are cantilevered on the left and right sides of the, and the swing members are alternately inverted to actuate the raw seaweed from the side to the screw conveyor. Sending the seaweed to the upper part after scooping it up, or conversely, flipping it over and sending the raw seaweed from the upper part to the screw conveyor and then sending it back to the side part, the raw seaweed is screwed up. While being properly filled between the conveyors, it is sent quantitatively to the seaweed cutting machine and shredded.

In this seaweed cutting machine, a pair of right and left swing members can be alternately operated in the forward and reverse directions, so that FIGS. 5 and 9 (a) to (f) of Japanese Utility Model Publication No. 56-49354 and Japanese Utility Model Publication No. 56-
FIG. 4 and FIG. 5 (a) to (c) of Japanese Patent Publication No. 49355,
Alternatively, as shown in FIGS. 4 and 5 (a) to (c) of Japanese Utility Model Publication No. 56-50793, a drive gear and a driven gear having the same diameter on the left and right sides are engaged with the rotary shaft of the swing member. An L-shaped rocking lever is loosely fitted coaxially with one of the drive gears, and a cross-shaped reversing member is urged and supported by a spring at the tip of the rocking lever to rock. By connecting the crank lever to the base end portion of the lever and rotating the crank lever, the engagement between the engaging claws protruding from both ends of the reversing member and the drive gear is alternately switched. The swing member is configured to invert forward and backward within a range of an appropriate swing angle.

(Problems to be solved by the device) However, in this type of seaweed cutting machine, when a large amount of raw seaweed mixed in long and short is put in the seaweed tank, the left and right swing members are alternately inverted to screw the raw seaweed. When the swing member functions such as sending it out toward the conveyor, scooping it up, or conversely inserting it back, an excessive load may be applied to it.

If a large amount of raw seaweed containing long seaweed alga is scooped up to the upper part of the swing member while being hooked, it causes the weight of the raw seaweed scooped up on the swing member. Due to the excessive load of the swing member, the engaging claws of the reversing member are sometimes disengaged, the swing member becomes free and descends. This may impair the quantitative delivery of seaweed.

In particular, when trying to process a large amount of raw seaweed with this type of seaweed cutting machine, there is necessarily a tendency to always supply a large amount of raw seaweed to the seaweed tank to cut the seaweed. It is necessary to deal with the certainty of the operation of the swing member regardless of the supply amount of. In this respect, in the case of the latter seaweed blender described above, the drive gear and the driven gear are meshed with the rotary shafts of the left and right swing members, and the drive gear is directly rotated by the drive motor that rotates in the forward and reverse directions. By operating the swing member, the swing member is reversed.

Therefore, there is no room for problems like the case of seaweed cutting machine, but instead, a dedicated drive motor for rotating the swing member in the forward and reverse directions is required, which is not always efficient from a device perspective. It is hard to say that.
