Shell conveying posture correction device for bivalve shell automatic piercer

Abstract

The purpose of the present invention is to shift bivalves onto a turn table part promptly and smoothly by appropriately correcting the posture of bivalves during conveyance without being affected by the properties of the bivalves, and to perform accurate drilling or improve drilling efficiency by improving accuracy in positioning the shifted bivalves. To achieve the purpose, the present invention comprises: an attachment part (25a) attached to an endless shape body in which a plurality of correction jigs installed at a bivalve conveyance unit (20) are able to rotate; an inclined part (25b) installed so as to allow a correction surface (25d) to be inclined at an obtuse angle; and a standing part (25c) continuing from the attachment part (25a) and also continuing from the inclined part (25b). The height (H1) of the standing part (25c) is smaller than the height (H2) of an ear-shaped protrusion (3) of a conveyed bivalve. Due to the presence of the standing part (25c), the posture of the bivalve can be corrected without being affected by the shape of the side edge (3e) of the ear-shaped protrusion. As the standing part (25c) of a correction plate becomes higher on the conveyor (21), the correction plate maintains the alignment state of bivalves (1), thereby promoting the stabilization of the corrected posture.

Description

technical field [0001] The present invention relates to the cultivation of bivalve molluscs such as scallops, and more particularly to a mechanical shellfish transportation posture correcting device that perforates holes for insertion of locking pins in ear-shaped protrusions of shells. Background technique [0002] Such as Figure 14 As shown, for example, the two shells of the scallop 1 overlap each other at most of the ear-shaped protrusion 3 of the shell, but there must be a part (one piece 3c) consisting of only one shell on one side of the ear-shaped protrusion 3. Such as Figure 15 As shown, the cultivation of the scallop 1 is carried out by inserting the locking pin 5 into the ear-shaped protrusion 3, piercing the cultivation rope 7, and hanging the cultivation rope 7 in the sea. Here, whether the insertion position of the locking pin 5 is located at the two overlapping parts 3b of the two shells of the ear-shaped protrusion 3 or at one part 3c is an important consi...

Problems solved by technology

The transport of scallops 1 having the above-mentioned abnormally shaped ear-like protrusions 3 is difficult to be corrected

[0013] In the case of the straightening jig of the conventional machine, since there is no upright portion connecting the mounting portion and the bent portion 25f, it is difficult to adjust the mounting height of the straightening jig, and it may be difficult to perform straightening during transportation.

[0014] For example, if the bending part 25f is set at a higher position from the conveyor 21, the conveyor 21 will rotate to the left in the figure, and the jig 25' will move to the right in the figure. As indicated by the arrow, it is trapped between the conveyor 21 and the gripper 25', so there is a possibility that the gripper 25' will be damaged and damaged ( Figure 17 (C))

On the other hand, if the bending portion 25f is set at a lower position from the conveyor 21, the conveyor 21 rotates to the left in the figure, and the jig 25' moves to the right in the figure, so there is a possibility of correction by rotation. The pose of Scallop 1 remains unstable while Scallop 1 continues to rotate with concern ( Figure 17 (D))

[0015] In the past, shellfish were transported by utilizing the momentum of shellfish transportation and the movement of the center of gravity of shellfish, so no special countermeasures were taken to correct the transfer and positioning, so the posture had to be corrected in the feeding direction of shellfish, so the efficiency of piercing was extremely low

[0016] In the case that the transfer of the shell cannot be performed smoothly and properly, the rate of failure or failure is increased due to piercing at an inappropriate position, and the hole is not completely penetrated.

[0017] In fact, it is often the case that the operator continues to work without paying attention to the above-mentioned defects such as improper perforation and non-perforation.

If the above-mentioned defective shellfish is mixed more, then when the operation of installing shellfish on the rope for breeding is carried out, the work efficiency will be significantly reduced.
