After loading the cartridge 155 of No. 1 respectively, the respective operating portions are brought into the state shown in FIGS. 13 and 6, and the rope 3 is given an appropriate tension by the rope tension portion 31. Next, one juvenile shell 5 is placed on each of the first and second juvenile shell supporting surface portions 23 and 24 of the shell seat portion 21 by hand, and the juvenile shell 5 is further placed on the first or second juvenile shell positioning portion 61, respectively. , 62, the ear 5a of the juvenile 5 on the right side, the rope 3 and the juvenile 5 on the left
The ears 5a of the are arranged in a laminated manner. In this state, the juvenile shell 5 is temporarily pressed by the brushes 92 and 93. Next, when the starting foot switch 15 is stepped on from this state, the drill body 73 descends together with the support member 72, and along with this, the pads 94, 95 and the drill guide 74 descend in advance, and the left and right juxtapositions are lowered. The shellfish 5 is pressed down (the pads 94 and 95 are slightly ahead), and then the through holes 6 and 7 are formed by the drill 76. Next, when the drill 76 is raised, the locking tool 151 causes the push-up rod 1 of the locking tool supply portion 121 to move.
It is pushed up by 29 and pierced through the through holes 6 and 7 from below. Next, as the drill 76 continues to move upward, the pads 94 and 95 and the drill guide 74 are separated from the juvenile shell 5, and then the rope retainer 37 of the first rope lock portion 32 of the rope tension portion 31 is raised and the second rope lock is performed. The rope tension presser 34 and the rope lock 48 of the portion 33 are lifted to release the tension applied to the rope 3. When the rope retainer 37 moves up, the spring mechanism 28 causes the juvenile shell push-up lever 26 to return upward to lift the left and right juvenile shells 5 sandwiching the rope 3 in the middle, and then the rope transfer unit 141 moves the rope 3 to the rope 3. One cycle is handed to the opposite side of the shell seat 21. As a result, the work is completed for one cycle, the mounting state as shown in FIG. 29 is realized, and thereafter, this is repeated the required number of times. Therefore, the above device has the following effects.

Since the attachment of the locking tool 151 to the rope 3 and the attachment of the juvenile shell 5 to the locking tool 151 are performed substantially at the same time, the work efficiency is good. Further, since two fry shells 5 are simultaneously attached to one locking device 151, this also improves the working efficiency. Juvenile shell holder 9 that prevents the misplacement of juvenile shell 5 during work
1, and the juvenile shell presser portion 91 is provided with brushes 92, 93 for temporarily holding the juvenile shellfish 5, and pads 94, 95 made of a rubber-like elastic material for holding the juvenile shellfish 5 and having an excellent anti-slip effect. Because of the provision of and, the juveniles 5 can be fixed reliably and stably. Therefore, during the work, the juvenile shell 5 is effectively prevented from being displaced, so that the through hole 6 can be accurately formed in the ear portion 5a of the juvenile shell 5 and the locking tool 151 can be accurately attached to the through hole 6. Can be pierced. Further, the brush 92, 93 and the pads 94, 95 have a structure in which the juvenile shell 5 is strongly pressed and positioned step by step according to the progress of the work, and since the pressing force is strengthened as necessary, the work is smoothly performed. You can proceed to. To the rods 79 and 82 that suspend the drill guide 74,
An engaging portion 81 that engages with the support member 72 and specifies the relative lowering limit of the rods 79 and 82 with respect to the drill body 73 is provided, and the engaging portion 81 is elastically biased downward above the engaging portion 81. Since the spring means 86 is provided,
The drill guide 74 descends to come into contact with the ear portion 5a of the upper juvenile 5, and then the drill guide 74 rises to emerge the upper juvenile 5.
The spring length L ₁ is kept substantially constant until the drill guide 74 is separated from the ear portion 5a of the fry 5 by a substantially constant spring force.
Press. Therefore, an excessive load is prevented from being applied to the juveniles 5, so that the juveniles 5 can be prevented from being damaged by an excessive load.

Rod 9 with pads 94 and 95 suspended
8, 101, 104 are engaged with the support member 72 of the drill portion 71 to engage the rods 98, 101, 1 with respect to the drill portion 71.
The engaging portion 100 that specifies the relative lower limit of 04 is provided, and the spring means 107 that elastically biases the engaging portion 100 downward is provided on the upper side of the engaging portion 100, so that the pads 94 and 95 are provided. There during the period from contact with the shell body portion 5f of the spat 5 lowered to pad 94, 95 is separated from the shell body portion 5f of the spat 5 rises, the spring length L ₁
Is kept substantially constant, and the pads 94 and 95 press the juvenile shell 5 with a substantially constant spring force. Therefore, an excessive load is prevented from being applied to the juveniles 5, so that the juveniles 5 can be prevented from being damaged by an excessive load. Since the rope tension portion 31 for tensioning the rope 3 at the time of work is provided, the through hole 7 is formed in the rope 3 in a state where the rope 3 is tensioned and the fibers of the rope 3 do not easily escape from the drill 76. It Therefore, it is possible to form the through hole 7 having a predetermined size corresponding to the thickness of the locking member 151. Moreover, since the locking tool 151 is pierced through the through hole 7 in a state where the rope 3 is tensioned and the through hole 7 is sufficiently opened, the locking tool 151 having a predetermined thickness is penetrated. The hole 7 can be pierced successfully. The rope tension part 31 does not pull the rope 3 in the longitudinal direction, but rather the first and second rope lock parts 3
Since the rope 3 is fixed at two points by means of Nos. 2 and 33, and the rope 3 is tensioned by pressing the intermediate portion substantially downward by the rope tension presser 34, the first and second rope lock portions 32 are provided. , 33 and the structure of the rope tension presser 34 are extremely simple. Further, the structure of these respective parts is extremely simple, but the rope 3 can be reliably and repeatedly tensioned, and it is possible to provide a rope tension structure suitable for use in this kind of ear suspension device.

Regarding the shape of the locking member 151 and the fact that the locking member 151 is a sheet-like cartridge 155, the following effects are obtained. The locking tool 151 is a locking tool body 152 having a substantially rod shape.
Since it has a simple shape in which a pair of juvenile shell locking portions 153 and 154 are provided at both ends of the, its molding is easy. When the grown scallop 5 is strongly pulled in an attempt to remove it from the rope 3, the locking device main body 152 is broken at somewhere in the longitudinal direction, and the locking device 151 is released from the state in which it is prevented from coming off from the rope 3. It Therefore, the lock body 152
It is possible to easily remove the entire locking device 151 from the rope 3 without further cutting it elsewhere. Since a large number of locking members 151 are collected as a sheet-shaped cartridge 155, handling such as loading is easy.
