Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to aquaculture of bivalves such as scallops, and more particularly to an apparatus for drilling a hole for inserting a locking pin into an ear projection of a shell.
[0002]
[Prior art]
As shown in FIG. 10, for example, the scallop 1 has a seashell ear projection 3 in a state in which two shells overlap with each other, but only one shell is on one side of the ear protrusion 3. The part (one piece part 3c) consisting of always exists. As shown in FIG. 11, the scallop 1 is cultivated by inserting a locking pin 5 into the ear projection 3 and piercing the cultivating rope 7 and suspending the cultivating rope 7 in the sea. Here, whether to insert the locking pin 5 into the two-piece portion 3b or the one-piece portion 3c in which the two shells of the ear projection 3 are overlapped is not considered from both the viewpoint of shell growth and work efficiency. It is an important problem that must not be.
[0003]
`` Opening one sheet '' is advantageous for scallop growth because it is difficult to damage the scallop mantle, it does not force the ligament when drilling, and it is easy for the scallop to open its mouth during predation It has been known.
[0004]
On the other hand, since the locking pin 5 is drilled in the larvae, from the viewpoint of work efficiency, “two sheets” are drilled in the two-part portion 3b rather than “one-piece opening” in which the small-area part 3c is drilled. "Open" is better. However, recently it has been avoided to open two sheets, which may cause shell growth failure or drowning, and it is desirable to open one.
[0005]
Opening one is very difficult for the following reasons. First, the perforated part is a single piece portion 3c that is slightly present in the shell-like projection 3 of the shell, and the single piece portion 3c is even smaller because the target shell is a juvenile shellfish. For example, a diameter of about 2 mm is appropriate for a 6 cm juvenile shellfish. In addition, the shell has an irregularly curved shape and is slippery and difficult to position because it is wet with seawater.
[0006]
If the drilling fails, the shell-like projections 3 of the shell may be damaged, causing a so-called “shell crack” phenomenon, making it unsuitable for aquaculture or causing breakage of the tool.
[0007]
By the way, the scallop 1 has the front and back sides, and the black side is the front side and the white side is the back side. Adherents such as parasites often adhere to the surface, and these parasites adhere unevenly and hard to the shell surface, forming large irregularities on the shell surface. For this reason, when punching by pressing the surface of the shell, the shell 1 may be repelled by the attached matter, and the holding of the shell 1 is not stable. Therefore, it has been necessary to work after hitting off these deposits.
[0008]
Therefore, for example, an apparatus has been attempted in which shells are placed on a conveyor conveyor in an inclined state, and the shells are conveyed and perforated by pressing the shells from above using the weight of the shells.
[0009]
However, even in such an apparatus, when the surface of the shell during transportation contacts the screw of the conveyor, the shell is blown off and the operation becomes impossible. Therefore, it is insufficient to fix stably depending on such an apparatus, and the above-described drawbacks cannot be solved.
[0010]
[Problems to be solved by the invention]
The object of the present invention is to eliminate the above-mentioned drawbacks and to accurately drill holes at predetermined positions of the ear-like projections of the shell.

The scallop 1 is inserted from the insertion port 29 with the surface facing upward.
[0015]
A turntable unit 30 is provided adjacent to the shell conveying unit 20. The turntable unit 30 includes a turntable 31 and is installed orthogonal to the conveyor 21. The turntable 31 includes a plurality of (eight in the embodiment) tables 33 attached to the peripheral surface of a circular drum 32 that rotates intermittently. Each table 33 is formed of a flat plate, and a first positioning post 34 and a second positioning post 35 that constitute a positioning portion are provided on an upper surface of the table 33, and an ear receiving portion 37 that receives the rear ear-like protrusion 3b therebetween. Project. A drilling position 39 where the drill 51 moves downward is formed between the ear receiving portion 37 and the first positioning post 34 (FIG. 4B).
[0016]
The first positioning post 34 is a relatively large-diameter stainless steel post formed in a hollow cylindrical shape, and a circular surface 34e is formed on the scallop 1 side. An upper portion of the first positioning post 34 adjacent to the drilling position 39 is slightly cut 34 f so as not to obstruct the downward movement of the drill 51. The second positioning post 35 is a stainless steel post, the central portion of which is formed in a concave arc shape, and is provided side by side with the first positioning post 34 so that the front ear-shaped protrusion 3a hits.
[0017]
The first positioning post 34 forms point a that contacts the side edge 3d of the shell and point b that contacts the rear ear projection 3b. The second positioning post 35 forms a point c that contacts the front ear-like projection 3a of the shell.
[0018]
The pressing unit 40 includes a first pressing unit 41 and a second pressing unit 44.
[0019]
The 1st press means 41 consists of a stainless steel plate formed in the shape of a tongue piece, and can rotate to a forward / reverse direction. When the scallop 1 is in the horizontal state indicated by “1b” in FIG. 4, the first pressing means 41 comes into contact with the ventral side edge of the shell, and the scallop 1 is moved in the linear direction indicated by the arrow X in FIG. 5. Press. The lower part 41a of the first pressing means 41 is bent to facilitate the pressing of the belly side edge 3e of the shell. 42 is an elevating body to which the first pressing means 41 is locked, and moves the first pressing means 41 in the scallop 1 direction when moving downward. Reference numeral 43 denotes a tension spring that returns the first pressing means 41 to its original position.
[0020]
The second pressing means 44 is formed by attaching a pad 45 made of urethane rubber to a plate 44a made of stainless steel and is rotatable in forward and reverse directions. When the scallop 1 is in the horizontal state indicated by “1b” in FIG. 4, the second pressing means 44 rotates in the direction indicated by the arrow Y in FIG. 5, and at this time, the pad 45 contacts the front ear projection 3a. Touch. The pad 45 is inclined diverging upward direction abuts pad surface 45a is in front lugs 3a. The second pressing means 44 has a cam follower 46, and rotates in the forward and reverse directions when the cam follower 46 makes contact following the rotating cam 47. 48 is a tension spring that urges the second pressing means 44 toward the scallop 1, and 49 is a bearing of the rotating shaft 44 b of the second pressing means 44.
[0021]
The piercing portion 50 is composed of a drill 51 that moves up and down. Reference numeral 52 denotes a motor 52 that rotates the drill 51. The drill 51 is drilled after the scallop 1 is positioned and fixed at a predetermined positioning and drilling position of the turntable 31 and then drilled.
[0022]
The scallop 1 introduced with the surface facing upward from the insertion port 29 is supplied to the turntable 31 by the conveyor 21 (FIG. 3A). The scallop 1a (shown in FIG. 4) pushed by the plate 25 during the conveyance and rotation of the conveyor 21 is placed on the table 33.
[0023]
As the turntable 31 rotates, the scallop 1a comes to the positioning / drilling position indicated by "1b" in FIG. At this time, the scallop 1b is in a horizontal state, but the positioning is still incomplete as shown in FIG.
[0024]
Next, the first pressing means 41 descends and hits the belly side edge 3e of the shell, and presses the scallop 1 in the direction of the first positioning post 34 and the second positioning post 35.
[0025]
At the same time, the second pressing means 44 rotates and hits the lateral end portion of the front ear-like projection 3a of the shell, and presses the shell in the direction of the first positioning post 34 (FIG. 5B).
[0026]
The shells supplied to the turntable 31 have various supply conditions such as size, shape, and posture, and are not necessarily in contact with each contact point of the positioning post as ideal.
[0027]
That is, the scallop 1 is composed of a total of three points including the points a and b of the first positioning post 34 and the point c of the second positioning post 35 by the pressing of the first pressing means 41 and the second pressing means 44. It is desirable to abut. However, since there are various supply conditions, the first pressing means 41 should contact the point a of the first positioning post 34 and the point c of the second positioning post 35. May be touched.
[0028]
Even in such a case, since the second pressing means 44 presses the front ear-like projection 3a of the scallop 1, when the shell 1 is in contact with the point c, it is guided to slide at the point c. The direction is slightly corrected and abuts the first positioning post 34 at two points.
[0029]
Therefore, the scallop 1 is reliably positioned at a predetermined position.
[0030]
In this state, the scallop 1 is continuously pressed by the first pressing means 41 and the second pressing means 44.
[0031]
Therefore, the scallop 1 is stably fixed at a predetermined position.
[0032]
In this state, the drill 51 moves downward to pierce a predetermined piercing position 39 of the one portion 3c of the ear-like protrusion 3 of the shell. Thereby, the locking hole 2 (shown in FIG. 10) for inserting the locking pin 5 is formed.
[0033]
Therefore, the scallop 1 can be prevented from shaking during drilling.
[0034]
The perforated scallop 1 (shown as “1c” in FIG. 4A) is dropped and carried out by the rotation of the turntable 31. During the positioning / drilling, the rotation of the turntable 31 is stopped.
[0035]
According to the said embodiment, the positioning and fixing of the scallop 1 are ensured not only planarly but also three-dimensionally.
[0036]
This point will be described in detail. Since the scallop 1 is pressed from different directions by the first pressing means 41 and the second pressing means 44, it is supported at three points by adding three contact points of the positioning posts 34 and 35 and contact by the pressing means 41 and 44. By this, it is firmly fixed at a predetermined positioning / drilling position on the table 33.
[0037]
Therefore, an accurate perforation can be ensured and one piece can be opened which is advantageous for the growth of the scallop 1.
[0038]
Further, the “positioning” by the three contact points and the “fixing of the shell 1” by the five subsequent contact points are continuously performed, so that the working efficiency is improved.
[0039]
When the drill 51 comes into contact with the drilling position 39 of the lug 3 and the drilling starts, the scallop 1 has a spherical shape and has only one contact point with the table 33. Therefore, as shown by an arrow in FIG. Try to rotate clockwise. However, the pads 45 of the second pressing means 44 because of the inclined diverging upward direction, some of the shells before lugs 3a 3a 'is bite into the pad 45, by wedge effect, during drilling Rebound movement such as tilting and wobbling of the shell 1 is prevented (FIG. 7). Therefore, the positioning and fixing of the scallop 1 are further improved.
[0040]
The introduced scallop 1 is not pressed against the surface at all until it reaches the positioning / drilling position of the turntable 31 from the conveyance path. Therefore, it is possible to work without being substantially affected by the above-mentioned deposits during conveyance and drilling. That is, the scallop 1 can be stably held and drilled accurately.
[0041]
The present invention is not limited to the embodiment described above. For example, the contact surface of the pad 45 of the second pressing means 44 can be formed flat (FIG. 8). Also in this case, as in the above-described embodiment, a part 3a ′ of the front ear-like projection 3a of the shell bites into the pad surface 45a of the pad 45 made of urethane rubber, and the recoil operation of the scallop 1 is prevented.
[0042]
The pressing by the second pressing unit 44 may be a linear direction similar to the first pressing unit 41 and may be a direction orthogonal to the pressing direction of the first pressing unit 41. In this case, the pressing mode of the second pressing means 44 can be the same as [0044].
[0043]
The material of the pad 45 is arbitrary as long as it is an elastic material.
[0044]
The shape and pressing mode of the first pressing means 41 are not limited. For example, a push bull solenoid, a rotary solenoid, an air cylinder, an electric cylinder or the like may be used. However, the machine as in the above embodiment is preferable because it is more reliable and lower in cost.
[0045]
The ear receiver 37 may not be provided.
[0046]
The positioning post can be formed of a single member that is in contact with three points. Further, the table 33 and the positioning posts 34 and 35 may be integrally formed. The peripheral end face shape of the positioning post is also arbitrary.
[0047]
The first positioning post 34 and the second positioning post 35 may be solid, and the shape of the peripheral end surface thereof is arbitrary as long as three-point contact is possible.
[0048]
The supply method of the scallop 1 to the turntable 31 is arbitrary. For example, it can be supplied by hand without using the conveyor 21.
[0049]
The direction of the shell to be positioned and fixed is arbitrary. For example, the shell can be perforated in a vertical state.
[0050]
Further, the member for positioning and fixing the shell is not limited to a flat shape such as a table.
[0051]
The shell to be perforated is not limited as long as it is a bivalve.
[0052]
It is also possible to give order to the work procedures of the first pressing means 41 and the second pressing means 44. For example, when the turntable 31 rotates and stops at the drilling position, the first positioning post 34 and the second positioning post 34 are first pressed by the first pressing means 41 while the scallop 1 tries to jump out to the discharge side by centrifugal force. It is conceivable to press the post 35 side and then finally correct the scallop 1 posture by the second pressing means 44.
[0053]
Further, as shown in FIG. 9, the second positioning post 35 can be moved, and the distance between the first positioning post 34 and the second positioning post 35 is adjusted so as to be adapted to the size of the scallop 1. You can also. For example, in the case of a large scallop 1 indicated by a one-dot chain line, the second positioning post 35 is moved to a position indicated by a thick one-dot chain line.
[0054]
The bivalve automatic punching machine according to the present invention is particularly effective for drilling the one-piece portion 3c of the ear-like protrusion, but does not prevent application to the drilling of the two-piece portion 3b.
[0055]
【The invention's effect】
Thus, according to the bivalve automatic perforating machine according to the present invention, it is possible to accurately perforate at a predetermined position of the ear-like protrusion of the shell. Moreover, the growth improvement of shellfish and the improvement of work efficiency can be made to make compatible.
