Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic shell ear hanging apparatus for automatically hanging a shell, such as a scallop, on an aquaculture rope through its ear, and more particularly to an ear for a bivalve aquaculture rope. The present invention relates to a device in which the suspension can be freely switched to open one or two.

[0002]

2. Description of the Related Art A shellfish drilling operation must be performed with the shellfish positioned at a predetermined position. For example, when perforating ears of a shell such as a scallop, one or two openings are made. The ear 7a of the scallop 7 has a large portion of two shells overlapping each other, but a portion consisting of only one shell always exists on one side of the ear 7a. Then, the formation of a through hole for hanging ears in a portion (two ears) 7b where two shells overlap (“two ears”) is referred to as “opening two shells”.
Forming a through hole for hanging ears in the sheet ear portion 7c is referred to as "opening one sheet". It is known that opening one piece is better for growing the scallop 7 because it does not hinder the growth of the shellfish. However, since the single ear 7c has a small target (for example, a shell having a shell height L of 80 mm is 3 mm).
If the positioning is not accurate, the ears 7a of the scallop 7 are damaged by the perforation, and the ears cannot be hung.
Therefore, in many cases, two shells are opened until the shell becomes larger, and one shell is opened after the shell becomes larger.

[0003] In the conventional one-sheet opening, a two-sheet opening device is provided with an optional one-piece gauge, and the shell must be pushed by hand to the piercing position to open one sheet. This is shown in FIG. First, shellfish 213, 213
There is a shell holder pedestal 201 provided with a contact wall 217 to which the ears 215 and 215 of the shell holder 215 are attached.
At the top, shells 213 and 213 are horizontally inserted from both left and right sides of the shell holder pedestal 201 by a manual operation of an operator. This insertion work is performed by the ears 2 of the shells 213 and 213.
15 and 215 are performed until they contact the contact walls 217 and 217, respectively. Thereby, the pre-set culture rope 219 is connected to the ears 215, 21 of the shells 213, 213.
5 causes a state of being sandwiched from above and below. Thereafter, perforation work and ear suspension work are performed in that state.

[0004]

However, according to the above-described method, in either case of opening one sheet or two sheets, the shell 213 disposed below has the ear 21
5 cannot be visually determined whether or not 5 is in contact with the contact wall 217 and is inserted in a predetermined posture.
7), and the situation had to rely on the feelings of the workers. Therefore, a long time and skill are required for the accurate positioning operation, and there is a problem that the operation efficiency is low. In other words, the hanging of the ears of the shell is a delicate work of drilling with a small drill called the ear of the young, and the surface of the young is slippery because it is wet, and if you make a mistake one step you may hurt your hands It is dangerous work. The operation with the conventional device is dangerous because it is performed right below the descending drill, and therefore has become a very tired nerve operation. For this reason, there was a problem that only the skilled worker could use it.

In some cases, the positioning of the shells 213 and 213, particularly the shell 213 disposed below, is insufficient. In such a case, the shell 213 cannot be fixed to the culture rope 219. there were. That is, when the predetermined drilling operation cannot be performed on the ear portion 215 of the shell 213 disposed below, the ear hanging on the culture rope 219 becomes impossible.

[0006] Further, in the conventional apparatus, for opening one sheet,
The shell hold pedestal 201 for opening two pieces is separate from each other,
In order to open one, it was necessary to separately provide a dedicated gauge as described above. In addition, this additional work was impossible for the user, and had to be commissioned to a specialized company (usually a manufacturer). In addition, the shell-hold pedestal 201 for opening one sheet has a shell-shell pedestal 201 for large shellfish and small shellfish in addition to the standard shellfish. Because the degree of growth of shellfish varies depending on the location and time of the catch, the size of the shellfish often varies from day to day. Therefore, it is necessary to use one open or two open depending on the size of the shellfish caught on that day. However, it is practically impossible to request a specialist to perform the switching operation each time.

The present invention has been made on the basis of the above points, and an object of the present invention is to make it easy to switch between opening one or two sheets when hanging a shell on a culture rope of a shell by a machine. The purpose is to be able to.

Another object of the present invention is to automatically and reliably position and hold a shell at a predetermined position in a predetermined posture regardless of whether one or two sheets are opened. The purpose of the present invention is to perform drilling / attachment work in a state corresponding to the growing condition of the scallop, thereby greatly improving work efficiency.

[0009]

In order to achieve the above object, the present invention provides an automatic apparatus for suspending an ear of a clam, which comprises feeding a shell fed in a certain direction with an ear portion directed downward to a culture rope. In a device provided with shellfish transport means for transporting along the shell and attaching the shell to the culture rope with a locking pin, stopper means provided in the middle of the transport path by the shell transport means for stopping the shell to be transported at a predetermined position is provided. When opening the shell, the shell is stopped in a substantially horizontal state by the stopper means. In this state, the ear of the shell is pierced. When the shell is opened, the shell is tilted downward in the transport direction and at the intersection of the shell and the ear. The shell is stopped while the formed reference recess is in contact with the stopper means, and in this state, the ear of the shell is pierced so that one or two can be opened and switched freely. Further, in the automatic shell ear hanging device according to the first aspect, a carrier receiver on which the carrier of the shellfish transporting means is placed is freely movable in a transport direction or a reverse transport direction. Further, in the automatic shell-and-ear suspension device according to claim 1 or 2, the carrier receiver is vertically movable. Further, in the automatic shell ear suspension device according to claim 1,
The transporter of the shell transporter is inclined from a tilt start point formed on the tip of the transporter receiver. Further, in the automatic clam ear hanging device according to the first aspect, the carrier of the shell transporting means is formed with a step from the front end of the carrier receiver. Further, in the automatic shell ear hanging device according to the first aspect, a gap is formed between the ear of the shell and the carrier when one sheet is opened. Further, in the automatic shell ear hanging device according to the first aspect, the stopper means is rotatable. Further, in the automatic shell ear hanging device according to the first aspect, the shell contact portion of the stopper means is provided to be inclined at a predetermined angle. Further, in the automatic shell ear hanging device according to the first aspect, shell ear contact means is provided in the middle of the transport path by the shell transport means and before the stopper means. According to a ninth aspect of the present invention, in the automatic shell ear hanging device, the shell ear contacting means is provided integrally with the stopper means. Also,

It is possible to move to any place via these four casters 3. Incidentally, reference numeral 61 in the figure denotes a shell-lifting platform.

A shell positioning means 27 is provided on the upper surface side of the apparatus outer casing 1, and a shell conveying means 31 is provided below the shell positioning means 27. First, as to the shell conveying means 31, as shown in FIGS. 4 to 6, a driving pulley 33, a driven pulley 35, a belt 37 wound around the driving pulley 33 and the driven pulley 35, and a belt 37. And a pair of support belts 60, 60 operating at substantially the same speed as the transport speed of the belt 37. The shells 7, 7 are thrown into a front portion (position indicated by a solid line in FIG. 4) on the belt 37 of the shell transporting means 31 having the above configuration, and the support belts 60, 6
Thus, the sheet is conveyed while being supported and guided in contact with the reference numeral 0. The belt 37 is made of, for example, a fine mesh metal member or flat steel, and is made of a material that does not damage the shell 7 even if the shell 7 slips.

Shell stoppers 39 and 41 rotatably provided on shell stopper arms 38 and 40 are arranged at predetermined positions in the transport path by the shell transport means 31. As shown in FIG. 9, the shell stoppers 39 and 41 are used to easily correct the posture of the scallop 7 when one is opened.
The shell contact portion 41a is provided to be inclined downward. A rope receiver 42 on which the culture rope 51 is placed is provided between the shell stoppers 39 and 41, and the shell stoppers 39 and 4 of the rope receiver 42 are provided.
A shell ear patch 50 is fixed to the front of the front.

That is, the shell ear cover 50 is provided in the manner shown in FIGS.
As shown in FIG. 0, a concave groove 50a through which the culture rope 51 is inserted is provided in the center, and both sides 50b are formed so as to protrude outward, and the ears 7a, 7a of the shell 7 are brought into contact with the both sides 50b. Has become.

Reference numeral 71 denotes a movable belt receiver on which the belt 37 of the shell conveying means 31 is placed. The belt receiver 71 is formed in a box shape as shown in FIGS. The belt assist receiver 73 is formed in a hook shape, and eliminates the influence of the movement of the belt receiver 71 even if the distance between the driven pulley 35 and the belt receiver 71 changes. A movable center shaft 75 is provided at the left end of the belt receiver 71, and the center shaft 75 is moved right and left to move the belt receiver 71 in the transport direction or the opposite transport direction. A long hole 76 is provided on the side of the belt receiver 71.
The upper and lower adjustment shafts 77 are loosely fitted in the long holes 76. This allows the belt receiver 71 to move in the vertical direction. The belt receiver 71 is supported by the center shaft 75 and the vertical adjusting shaft 77, and is movably accommodated between a side frame (not shown) and the rope receiver 42.

The shells 7, 7 conveyed on the belt 37 of the shell conveying means 31 are restricted from being further conveyed by contacting the shell stoppers 39, 41, and their ears 7a. , 7a are brought into contact with the shell ear contact portion 50 and have a predetermined posture facing downward (the predetermined posture differs between opening one and two sheets, but this point will be described later).
At that time, the belt 37 of the shellfish conveying means 31 continues to be driven, and thus the shells 7, 7 are slipping on the belt 37. The shell stoppers 39 and 41 are shown in FIG.
As shown by the two-dot chain line, the shell stoppers 39 and 41 are closed first, and then the shell holding members 43 and 45 are closed after a predetermined time has elapsed. This shell stopper 3
The opening and closing timing of the shells 9 and 41 and the shell holding members 43 and 45 is set by a timer (not shown). The timing of opening and closing the shell stoppers 39 and 41 is not affected by the quality of the drilling / attachment work to the shell.

A pair of shell holding members 43, 45 are arranged outside the shells 7, 7 which are stopped with the ears 7a, 7a abutting the shell stoppers 39, 41 and the shell ear abutment 50. ing. As shown in FIG. 7, the shell holding members 43 and 45 are fixed to an arm member 47, and the arm member 47 is configured to be rotatable about a shaft 48. Further, a rod 49 of a cylinder mechanism (not shown) is connected to the arm member 47. When the rod 49 is extended by the cylinder mechanism, the arm members 47 and 47 rotate in the facing direction, and the shell holding members 43 and 45 hold the shell 7. Thereby, the pair of shells 7, 7 is regulated to a predetermined posture. At this time, the ear portions 7a of the shells 7, 7 have a shell ear patch 50 having a length shorter than the length of the ear portions 7a, 7a. Gap between
Is formed, thereby absorbing the thickness T of the body of the shell 7.

The shell stoppers 39 and 41, the shell holding members 43 and 45, the shell ear abutment 50, the belt receiver 71, and the like constitute the shell positioning means 27 described above.

An aquaculture rope 51 is extended on the shell transporting means 31 and between the pair of shells 7,7. The culture rope 51 is pulled out from a drum (not shown) and, as shown in FIGS.
It is pulled and stretched over one rope receiver 42, that is, between the pair of shells 7, 7 (more precisely, between the ears 7a, 7a of the pair of shells 7, 7). 52 is a rope retainer.

As described above, the shell stoppers 39, 41
And ears 7a, 7 of shells 7, 7
The earpiece member 50 to which a is applied is arranged. As described above, the pair of shells 7, 7 are arranged on both sides of the culture rope 51, and at this time, as shown in FIG.
Since the torso portion is inflated and has a certain thickness T, if two shells are arranged side by side and pressed from both sides, the shells 7, 7 will be inclined as shown in FIG. Then, the ear portions 7a, 7a of the shells 7, 7 are brought into contact with the ear covering portion 50, and the pair of shell holding members 4 already described.
By appropriately holding the shells 7 and 7 by the shells 3 and 45, the ears 7a and 7a of the shells 7 and
1 to form a gap G to keep the shellfish 7 in a substantially vertical state. As a result, the holding of the shell is stabilized without horizontal swaying in the vertical direction and rotation in the horizontal direction when the shell is placed in a horizontal state. In addition, even if the size L of the shellfish varies, the desired drilling / attaching operation can be reliably performed without being affected by the variation.

As shown in FIG. 1, above the place where the shells 7, 7 have stopped and their positions have been determined, ears 7a,
A piercing means 53 for piercing the culture rope 51 and the ear 7a of the shell 7 on the opposite side is provided. This piercing means 5
3 is provided with a drill 55, which is used to make a hole in the ear 7a of the shell 7, the culture rope 51, and the ear 7a of the shell 7 on the opposite side. On the opposite side of the perforation means 53, a locking pin insertion means 57 is arranged. That is, the perforation means 53 pierces the ear 7a of the shell 7, the culture rope 51, and the ear 7a of the shell 7 on the opposite side, and then the locking pin insertion means 57 arranged on the opposite side. Insert the locking pin 59 shown in FIGS.
Thereby, the pair of shells 7, 7 is attached to the culture rope 51. This point will be described in detail with reference to FIGS. Reference numeral 58 denotes a known supply drum, which is provided with a concave groove 58a for accommodating each locking pin 59 on the peripheral surface, and rotates intermittently. As shown in FIG. 14, a large number of locking pins 59 are supplied to the supply drum 58 in a continuous state in an endless manner.
Sent by pitch. Only after being pressed by the insertion pin 57a of the locking pin insertion means 57, the continuous pieces 59a, 5
9b is cut into individual locking pins 59 (FIG. 15),
The pair of shells 7 is attached to the culture rope 51 by inserting the shells 7 into the perforations (not shown) made by the drill 55.

When attaching the scallop 7 to the culture rope 51, the predetermined posture of the scallop 7 differs between opening one sheet and opening two sheets. As already mentioned, the belt receiver 71
Is movable in the left-right direction, and when two sheets are opened, the center shaft 75 is at the base end on the right side in the figure, and the scallop 7 comes into contact with the shell stopper 41 in a substantially horizontal state (FIG. 6A). At this time, the shell contact portion 41a of the shell stopper 41 is in contact with the ear 7a of the scallop 7, and the perforation P is made in the two ears 7b (FIG. 16). The same applies to the shell stopper 39 on the opposite side. FIG. 16A shows a case where the scallop 7 has a standard size (generally, about 50 mm <L <about 90 mm), and FIG. 16B shows a case where the scallop 7 is smaller than the standard. At this time, the shell contact portion 41a is in contact with the reference recess 8 formed at the intersection of the shell body 7d and the ear 7a.

On the other hand, when one sheet is opened, the fixing of the center shaft 75 is loosened by the handle 74, the belt receiver 71 is moved to the left in the figure, and the inclination angle of the belt 37 is adjusted.
5 is tightened and fixed (FIG. 6B). S indicates the inclination start point of the belt 37 formed on the tip of the belt receiver 71. The amount of movement of the belt receiver 71 is adjusted according to the size of the scallop 7. This point will be described in detail with reference to FIGS. When the belt receiver 71 is moved to the left, the inclination starting point S
17, the scallop 7 does not come into contact with the shell stopper 41 even when the center of gravity of the scallop 7 passes the inclination start point S as shown in FIG. 17 (FIG. 17A). The linear portion 7e leans against the shell contact portion 41a of the shell stopper 41 (FIG. B). Even in this state, since the belt 37 is transported in the direction of the arrow, the scallop 7 gradually moves in the transport direction while leaning against the shell stopper 41, and the shell contact portion 41a finally comes into contact with the reference recess 8. By the way, stop moving. At this time, the scallop 7 comes in contact with the shell contact portion 41a of the shell stopper 41 against the reference concave portion 8,
The ear 7a on the opposite side (left side in the figure) is in contact with the belt 37, and the posture of the scallop 7 is stabilized at these two points (FIG.
Although not shown in FIG. 17 in addition to the above two points, the scallop 7 is provided with the support belt 60 and the rope holder 5 already described.
2 and is fixed by the shell holding members 43 and 45, so that it stands up). That is, a gap G is formed between the ear 7a of the shell 7 and the belt 37 so that the shell 7 and the belt 37 do not interfere with each other. Therefore, in such a state, the perforation described above is made at the predetermined position P.

Incidentally, the amount of movement of the belt receiver 71 is appropriately changed depending on the size L of the scallop 7. When the size L of the scallop 7 is other than the standard size, FIG.
As shown in (1), it is not possible to cope only by moving the belt receiver 71 in the left-right direction. That is, FIG. 18A shows a case where the size is equal to or smaller than the standard size (for example, L of the scallop 7 is 45 mm). In this case, the scallop 7 tilts rearward (to the left in the drawing), and the ear 7a gets stuck between the mesh belts of the belt 37, thereby damaging either the scallop 7 or the belt 37. FIG. 18B shows a case where the size is equal to or larger than the standard size (for example, L of the scallop 7 = 100 mm).
In this case, since the center of gravity of the scallop 7 does not sufficiently project forward (to the right in the drawing) from the inclination start point S, the scallop 7 does not tilt down,
The perforation P cannot be made in a predetermined position. Therefore, in order to cope with such a case, the belt receiver 71 is moved up and down by the upper and lower adjustment shafts 77 and adjusted by setting the angle α. FIG. 19 shows a case where the size L of the scallop 7 is larger than the standard size (for example, L = 100 mm). In such a case, the belt receiver 71 is moved left and lowered to adjust. In addition, when the size L of the scallop 7 is smaller than the standard size, one sheet is not usually opened.

When the drilling operation and the locking pin insertion operation are completed, the culture rope 51 is moved by a predetermined amount, whereby the pair of shells 7 fixed to the culture rope 51 also move. Become. Next, the next pair of shells 7, 7
Is performed, and the same operation as that already described is performed. Thereby, the pair of shells 7, 7 are sequentially attached to the culture rope 51 at a predetermined pitch.

As described above, the following effects can be obtained with the automatic shell ear suspension device according to the present embodiment. First, when hanging the scallop 7 on the aquaculture rope 51, it is possible to switch between opening one or two with a simple operation. For this reason, it is possible to freely perform the drilling / attachment work in a state corresponding to the growing condition of the shellfish.

The shells thus fed are transported as they are by the shell transporting means 31. At this time, the shell stopper 3
By being stopped at a predetermined position by 9 and 41, even if the transport function by the shell transport means 31 is continued, the transport is stopped. In addition, at this time, the ears 7 of the shells 7, 7
The a and 7a are applied to the shell ear contact portion 50, and are pressed from outside by the shell pressing members 43 and 45. As a result, the ears of the shell become substantially perpendicular to the direction of piercing by the subsequent piercing and mounting means. As a result, even if the size L of the shell 7 varies, the desired drilling / mounting operation can be reliably performed without being affected by the variation. In addition, since the shellfish is placed vertically, even if dust is generated at the time of drilling, the dust falls downward, so that it is possible to prevent the guide 57b of the locking pin insertion means 57 from causing trouble due to dust or seawater. . In addition, even if the perforation / attachment work by the perforation means 53, the locking pin insertion means 57, or the like is unsuccessful for some reason, it can be conveyed and discharged by the shellfish conveyance means 31 as it is. The remaining work of the shellfish that could not be attached does not hinder the next operation.

The present invention is not limited to the above embodiment. First, as shown in FIG. 20, a roller 79 is provided in the conveyance path of the belt 37 of the shellfish conveyance means 31,
Even if a conveying path is formed by providing a step at the end of the belt receiver 71 (the right end in the figure), the same operation and effect as in the above embodiment can be obtained. Further, in the above-described embodiment, the scallop has been described as an example of the shell, but the invention is not limited thereto, and the invention can be applied to various bivalves. Also,
The shellfish stoppers 39 and 41 and the shell ear cover member 50 may be integrally formed. In addition, the way of putting shellfish is optional. It can be manually or mechanically loaded, and one shellfish
It may be charged one by one or a pair of two, or a plurality of lines. For example, two shellfish may be sequentially attached and fixed to a plurality of culture ropes at the same time. Further, the type and shape of the locking pin may be appropriately designed. Further, the mode of the stopper means is arbitrary. Even if the transport by the shell transport means is continued as in the illustrated embodiment, the shell may be physically stopped by the stopper means, or for example, it is determined that the shell is transported to the predetermined position. The detection may be performed by various sensors such as an optical sensor, an ultrasonic sensor, and a mechanical sensor such as a limit switch, and thereby, the shellfish conveying means may be stopped. Further, when the shellfish is detected by the sensor, the shellfish conveying means can be pressed from the outside without stopping the shellfish conveying means. Also,
Regarding the shell holding members 43 and 45, a mechanism for moving the rod 49 forward and backward is optional, and may be, for example, a cam mechanism or the like. Further, the arm member 47 may be directly rotated by the motor without using the rod 49.

For convenience, portions having the same function are denoted by the same reference numerals, and description thereof is omitted.

[0029]

As described in detail above, according to the automatic shell ear hanging apparatus of the present invention, when the ear of the shell is hung on the culture rope, it is possible to switch between opening one or two with a simple operation. Can be. For this reason, there is an effect that it is possible to freely perform the drilling / attachment work in a state corresponding to the growing condition of the shellfish. Also, in either case of opening one sheet and two sheets, the shellfish can be automatically and reliably positioned and held in a predetermined position in a predetermined position, thereby keeping the shellfish in a state corresponding to the growing condition of the shellfish. Drilling and mounting work can greatly improve work efficiency.
