Individually separated from the runner 86. The detached locking members 81 are individually fitted into the feed pitch concave portions 58 of the supply rotor 55, and are sent to the locking member protrusions 56 as the supply rotor 55 rotates. The supply rotor 55 rotates intermittently in each work cycle. The runner 86 continues to travel straight in the direction A and is discharged to the outside. The locking tool push-up portion 56 is provided with a push-up rod 59 for pushing up the locking tool 81, and further, as shown in FIG. 60 is provided in the shell part 21. The push-up guide 60 has a structure in which a plurality of equally arranged guide parts are opened radially outward at the moment of the push-up,
The guide 81 is guided so that one of the clam engaging portions 83 of the engaging member 81 is securely inserted into the through hole 6. Prior to the start of the operation, a large number of sheet-like cartridges 85 are stocked in a side-by-side stack in the cartridge stock unit 52, and are sequentially loaded one by one as the operation proceeds. For this reason, the cartridge stock section 52 is provided with a slider 63 that moves by the weight of the weight 62 suspended by the wire 61 and sequentially feeds the cartridge 85 in the stacking direction.

As shown in FIG. 21, the rope transfer section 71
Is provided with a pair of chucks 72 which releasably chuck the rope 3 and reciprocate in the direction indicated by the arrow.
, The rope 3 is manipulated (transported) in the longitudinal direction by a predetermined distance, the rope 3 is released, only the chuck 72 is returned, and the rope 3 is gripped again. The distance of one reciprocation (the distance between the locking members 81) can be adjusted by shifting the fixing position of the stopper 74 with respect to the rail 73.

When carrying out the ear hanging operation by the ear hanging device having the above-described configuration, the rope 3 and the cartridge 85 of the locking member 81 are respectively loaded, and then the first and second shell members 21 are manually operated. One of the young mussels 5 is placed on each of the two young mussel supporting surfaces 23 and 24, and the young mussel 5 is horizontally positioned in accordance with the first or second young mussel positioning portions 31 and 32, respectively. Ear 5 of the young shell 5
a, the ropes 3 and the ears 5a of the left-hand juvenile clam 5 are arranged in a layered manner. Then, when the foot switch 15 for starting is stepped on from this state, the drill guide 47 of the drill portion 41 and the drill body 45 descend sequentially, and the through-hole 6 is formed from above in the above-described three-layer laminated portion. And then
When the drill body 45 retreats (rises), the locking tool 81 is pushed up by the push-up rod 59 of the locking tool supply unit 51 so as to chase the drill body 45, and the through-hole 6.
Is pierced from below. Next, when the brush holding lever 42 is retracted (elevated), the young clam lifting lever 27 is returned by the spring mechanism 38, and the left and right young clams 5 sandwiching the rope 3 are lifted in the middle. As a result, the rope 3 is pulled toward the side opposite the shell 21 for one cycle. As a result, one cycle of the operation is completed, and the mounting state shown in FIG. 22 is realized, and thereafter, this operation is repeated a required number of times. Therefore, according to the above device, the following effects are obtained.

Attachment of the locking tool 81 to the rope 3 and mounting of the juvenile shellfish 5 to the locking tool 81 are performed almost at the same time, so that work efficiency is high. Locking tool 81
Since two juveniles 5 are simultaneously attached to the same, work efficiency is also good. After the drilling, when the drill body 45 retreats (rises), the locking tool 81 is moved to follow the drill body 45.
Is pushed up by the push-up rod 59 of the lock supply section 51 and pierced into the through hole 6 from below. Therefore, before the through-hole 6 of the rope 3 formed by twisting the fibrous material is closed, the locking tool 81 can be pierced into this through-hole 6, so that the failure rate of the piercing is remarkably small.

The shape of the locking member 81 and the locking member 8
The use of 1 as the sheet-like cartridge 85 has the following effects. Since the locking member 81 has a simple shape in which a pair of juvenile locking portions 83 and 84 are provided at both ends of a locking member main body 82 having a substantially rod shape, the forming is simple. That is,
Since it is only necessary to form the juvenile claws 83 and 84 at “two places” of the substantially main body 82, the shape and configuration can be simplified. It can be facilitated. When the grown scallop 5 is pulled strongly to remove it from the rope 3, the locking tool main body 82 is broken somewhere in the longitudinal direction, and the state in which the locking tool 81 is prevented from falling off the rope 3 is released. You. Therefore, the entire locking tool 81 can be easily removed from the rope 3 without further cutting the locking tool body 82 somewhere else. Since a large number of the locking members 81 are assembled as a sheet-like cartridge 85, handling such as loading is easy.

Next, the "single-opening" of the ear hanging culture will be described. As shown in FIG. 23, the ear 5 a of the scallop 5 is in a state where two shells are overlapped in most of the ears 5 a, but on one side of the ear 5 a, there is always a portion consisting of only one shell. Exists, and it is "opening two" to form a through-hole 6 in a part (hereinafter, also referred to as a two-piece part) 5b in which the two shells overlap each other. Part (hereinafter, also referred to as one sheet part) 5
Forming the through hole 6 in c is called "single-opening", and the latter one-opening does not hinder the growth of the shellfish, so that the growth of the scallop 5 is good. It has been known.

Considering the ear hanging device having the above configuration in this regard, as described above, this device makes the rear side 5d of the ear portion 5a abut against the ear backing walls 33, 36, and at the same time, as described above. The scallop 5 is positioned in the horizontal direction by abutting the one side 5e against the side walls 34, 37 of the ears, and the through hole 6 is formed at a fixed position from the rear side 5d of the ear 5a. It is at a distance. On the contrary,
Between the rear side 5d of the ear part 5a and the single part 5c, two parts 5 are provided.
There is a portion 5b 'of b, and the size of this portion 5b' varies depending on the size of the scallop 5. Therefore, in the positioning method by the above-described device, depending on the size of the scallop 5, a through hole 6 is formed in a part 5b 'of the two pieces 5b, or a through hole 6 is formed in one piece 5c. turn into.

On the other hand, the shell main body 5f and the ear 5a
Considering one concave corner 5g as a center, one piece 5c is located right next to the concave corner 5g, and this is the same regardless of the size of the scallop 5. Therefore, if the horizontal positioning of the scallop 5 is performed with reference to the concave corner portion 5g, the through hole 6 can be formed in the one-piece portion 5c without fail. For this reason, as shown in FIG. 24 and FIG. 25, as a device for the right-side juvenile shell 5, a pin-shaped one-piece The juvenile shellfish positioning part 91 is provided, and the juvenile shellfish 5 on the right side is positioned in the horizontal direction by making contact with the juvenile shell positioning part 91 so as to fit the concave corner portion 5g. As shown in FIGS. 26 and 27, a pin-shaped single-panel juvenile positioning unit 92 is provided at the front end of the ear side lining wall 37, as shown in FIGS. 26 and 27. The left juvenile clam 5 is positioned in the horizontal direction by making contact with the concave corner portion 5g so as to be fitted to 92. If the through holes 6 are formed immediately beside these juvenile shell positioning portions 91 and 92, the through holes 6 can always be formed in the single piece portion 5c regardless of the size of the juvenile shell 5. Accordingly, it is possible to promote the growth of the juvenile clam 5.

[0026] These single-pane juvenile clam positioning portions 9
A part or all of the shells 1 and 92 each have a shell part 21.
May be provided independently. That is, in another example shown in FIG. 28 and FIG. 29, the single-sheet opening juvenile shell positioning unit 91 for positioning the right juvenile shell 5 is formed by the shell seat 21.
And a single-opening juvenile shell positioning portion 92 for positioning the juvenile shell 5 on the left side is provided separately for the shell seat portion 21 and the above-described rope retainer 30a. Further, in this example, the right-side single-pane juvenile shellfish positioning portion 91 is formed in a block shape, and the concave corner portion 5g is fitted to the right-hand corner in front of the block-shaped single-pane juvenile shellfish positioning section 91. The right juvenile clam 5 is positioned in the horizontal direction by contact. Further, the left-side single-paneling juvenile positioning unit 92 is also block-shaped, and the block-shaped single-paneling juvenile-positioning section 92 is brought into contact with the left corner of the front side of the block-shaped single-paneling juvenile positioning part 92 so as to fit the concave corner 5g. The left juvenile 5 is positioned in the horizontal direction.
