Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sorting machine for shellfish and the like, which is used for sorting scallops by outer diameter size (size).

[0002]

2. Description of the Related Art Scallops A must be sorted by size at the time of aquaculture or shipping. This selection was previously done manually. Specifically, several sieves with different mesh sizes were prepared, and scallops were gradually selected from large mesh screens to small mesh screens to select several sizes. This sorting method has a poor work efficiency, and also puts a heavy burden on a worker who carries out the sorting.

Therefore, the applicant of the present application has previously described FIG. 10 and FIG.
The automatic sorter shown in 1 was developed and put into practical use. These sorters are provided with three downwardly inclined shooters B, and a relatively large sorting hole C is provided in the uppermost shooter B, and a slightly smaller sorting hole C is provided in the second shooter B. The holes C are formed respectively, and the screening holes C are not provided in the third-stage shooter B. Also, the lower end of the second-stage shooter B is attached to the frame K by a resilient urethane support rod D, and the arm E is attached to the bottom surface of the third-stage shooter B.
, And the arm E is rotated by a motor M so that the shooter B reciprocates in the longitudinal direction.

Further, in the automatic sorter shown in FIG. 10, the hopper F is provided on the rear side of the extension line of the uppermost shooter B. Then, when the shellfish A is put into the hopper F, the shellfish A is sent to the shooter B at the uppermost stage, slides down inside the shooter B, and slides down into the box G installed below the exit side.
Shell A that is smaller than the selection hole C of the shooter B while sliding down
Falls from the sorting hole C onto the second-stage shooter B,
The second-stage shooter B slides down and falls into a second box H installed below the shooter B. Also in this case, the shell A smaller than the selection hole C of the second-stage shooter B drops from the selection hole C to the bottom-most shooter B in the middle of sliding down, and then drops into the box I placed below the shooter B. Shellfish A are stored in the boxes G, H, and I according to size.

In the automatic sorter shown in FIG. 11, the hopper F
Is installed above the uppermost shooter B with the inclination opposite to that of the shooter B, and the bottom surface of the lower end (exit) side of the hopper F is slidably mounted on the rotatable roller O. It is supported, and its upper end is rotatably connected to the upper end of the elongated plate-shaped connector P. A lower end of the connector P is connected to the uppermost shooter B, and a triangular plate-shaped support piece Q is erected so that the upper part of the intermediate part is opposed to both sides in the width direction of the frame.
It is attached to a rotary shaft R that is rotatably provided in between. As a result, when the uppermost shooter B reciprocates back and forth, the lower end of the connector P moves in the same direction,
The upper end side of the connector P rotates together with the rotation axis R and swings in the opposite direction to the uppermost shooter B, and further, the hopper F reciprocates in the front-rear direction, and this reciprocal movement causes the shell A in the hopper F to move. Is vibrated and dropped onto the shooter B.

In FIG. 11, the shellfish A that has dropped from the hopper F to the uppermost shooter B slides down in the shooter B and then drops into a box G installed below the shooter B. In the middle of sliding down, a shell A smaller than the selection hole C of the shooter B drops from the selection hole C to the second-stage shooter B, slides down the second-stage shooter B, and is installed below the point 2 The second box H is dropped. In this case as well, a shell A smaller than the selection hole C of the second-stage shooter B falls from the selection hole C to the bottom-most shooter B while sliding down, and from the shooter B to the box I installed below the shooter B. After falling, the shellfish A is accommodated in each of the boxes G, H, and I according to size.

In the hopper F shown in FIG. 11, an outlet S is formed at the tip of a box having an upper opening, and the inside of the hopper F is gradually deepened from the upper end side for feeding the shellfish A to the lower end side. Further, the outlet S is provided with a stopper T for preventing the shellfish A from dropping at once. The stopper T is formed by mounting a metal plate having a width slightly wider than that of the outlet S with a gap provided in front of the outlet S.

[0008]

Although the automatic sorters shown in FIGS. 10 and 11 function reasonably well, they have the following drawbacks. ． It is easy for shellfish A to collect at the center of the outlet S of the hopper F in the width direction, and from there, the shellfish A collectively fall on the shooter B, and the shellfish A are not dispersed on the entire surface of the shooter B but fall on top of each other. is there. For this reason, a shellfish that would otherwise fall from the sorting hole C while sliding down the shooter B slips on another shellfish A and exits from the exit of the shooter B, and does not fall from the sorting hole C. Yes, the sorting accuracy is reduced. ． In order to drop the shellfish A evenly from the hopper F onto the entire surface of the shooter B for easy selection, it is considered that the shellfish A is put into the hopper F little by little or the shellfish A is sent to the shooter B little by little. However, this reduces work efficiency.

[0009] In order to solve the above-mentioned problem, the present applicant attaches a stopper T at the end of the outlet S as shown in FIG. 11 so as to prevent the stopper T from interfering with the shellfish A and causing the shellfish A to fall from the outlet S. Was developed. However, if a lot of shellfish A is supplied in the hopper F,
The shellfish A may flow at once from the upper part of the hopper F to the outlet S and concentrate at the outlet S, and the shellfish A may be clogged in the outlet S and not fall down, so that the sorting efficiency is lowered. ． When the shellfish A is clogged at the outlet S of the hopper F, the operator removes the jammed shellfish A by hand to improve the flow.
When the amount of shellfish A inside becomes small and the flow of shellfish A becomes poor,
There was a trouble that the worker had to send out the shellfish A by hand to improve the flow. Moreover, for this reason, there is a problem that the worker cannot leave the side of the hopper F and one worker is exclusively required.

[0010]. If it is difficult to disperse the shellfish A in the hopper F, the supply of the shellfish A from the hopper F to the shooter B and the vibration of the shooter B must be temporarily stopped before the shellfish A is dispersed, resulting in a significant decrease in work efficiency. To do. ． Shellfish A gathers on shooter B and falls, and shooter B
If it is jammed, the shellfish A sent later to the shooter B may overflow from the shooter B and fall outside if not noticed. Also, if the shellfish A accumulates on or is clogged on the shooter B, the shellfish A that will be sent later will pass over them, and the small shellfish A that should originally fall from the sorting hole C will not fall. May pass through the shooter B, so that shellfish A having different sizes may be mixed and the sorting accuracy may be deteriorated.

The object of the present invention is to prevent shellfish from being clogged in the hopper to make it difficult to drop into the shooter or to be supplied to the shooter in a lump, and to drop evenly from the entire width direction of the exit of the hopper to the shooter to smoothly and efficiently. It is to provide an automatic sorting machine for shellfish and the like that can be well sorted.

Second Embodiment A second embodiment of the automatic shellfish sorting machine of the present invention will be described in detail with reference to FIGS. In this embodiment, the rectifying body 5 is provided near the outlet of the hopper 4 in FIG.
3 is the same as that shown in FIG. 3 and is different from that shown in FIGS. 1 to 3 in the structure of the shooter 1. That is, FIGS.
The shooter 1 only reciprocates back and forth, but what is shown in FIGS. 3 and 4 is that the shooter 1 is provided with a diaphragm 6 that vibrates back and forth and up and down.

Of the three-stage shooters shown in FIGS. 4 and 5, the uppermost and second-stage shooters 1 are mounted with the substantially L-shaped guide rails 40 facing each other on both sides in the width direction of the frame 10 to support both rails 40. A vibration plate 6 having a width slightly narrower than the width between the rails 40 is placed on the surface 50 to enable vibration in the left-right direction, and a gap is formed between the vibration plate 6 on both width-direction edges 41 of the vibration plate 6. A long and narrow pressing member 42 is arranged so that the diaphragm 6 can be vibrated in the vertical direction, and the length of the diaphragm 6 is made slightly shorter than the length of the guide rail 40, and at the lower end of each guide rail 40. A die-shaped stopper 43 and a bolt-type stopper 45 are attached to the upper end so that the diaphragm 6 that vibrates in the front-rear direction does not come out in the front-rear direction.

A flat metal plate 44 is attached to the lower part of the shooter 1 of the first and second stages by lowering it from the diaphragm 6 by one step, and the scallop 3 slid down from the diaphragm 6 is attached to the metal plate 44. It is designed to be discharged to the outside guided by.

Sorting hole 2 of diaphragm 6 of top shooter 1
Has a diameter such that a scallop 3 smaller than a medium size can be sieved out, and the selection hole 2 of the diaphragm 6 of the second-stage shooter 1 has a diameter such that a small size scallop 3 can be sieved out. These diaphragms 6 can be easily pulled out from above the shooter 1 by removing the stoppers 45 attached to the upper ends of the guide rails 40, and the diaphragm 6 having a selection hole 2 of a desired diameter is formed. It can be exchanged.

In the automatic sorter shown in FIGS. 4 and 5, the rotary motion of the motor in the drive unit 18 is converted into the reciprocating motion of the crank rod 19 by the crank mechanism, and the reciprocating motion causes the swing arm 13 to center on the central axis 12. The rotary bearing 20 rotates on the upper end 14 of the swing arm 13 in accordance with the rotation.
The guide rail 40 of the shooter 1 connected via the back and forth reciprocally vibrates back and forth and rotates up and down. At this time, the diaphragm 6 reciprocates back and forth on the guide rail 40 and also vibrates vertically.

When the guide rail 40 reciprocates back and forth and rotates up and down as described above, the lower end portion of the connector 32 (FIG. 5) attached to the guide rail 40 reciprocates in the same direction to connect the guide rail 40. The upper end side of the child 32 rotates together with the shaft 31 to swing in the direction opposite to the shooter 1 (front-rear direction), and along with this, the hopper 4 reciprocally vibrates in the front-rear direction (reverse direction of the shooter 1). It also reciprocates vertically. The shellfish 3 selected by this vibration falls into the box 15 arranged below the tip of each shooter 1.

The hopper 5 of FIGS. 4 and 5 has the same structure as the hopper shown in FIGS. 1 to 3, and is attached to the shooter 1 in the same manner as in the case of FIGS. 4 and 5, and vibrates similarly to them. Is done.

[Embodiment 3] A third embodiment of the automatic shellfish selector according to the present invention will be described in detail with reference to FIGS. This embodiment is the same as that shown in FIGS. 1 to 3 in that the rectifying body 5 is provided in the vicinity of the outlet of the hopper 4, and the shooter 1 is shown in FIG.
Similarly to that shown in FIG. 5, the diaphragm 6 reciprocates back and forth on the guide rail 40 and also vibrates vertically. Figure 4,
What is different from that shown in FIG. 5 is the connecting structure of the hopper 4 to the shooter 1.

In FIGS. 6 to 8, the hopper 4 is installed on the uppermost shooter 1 while being inclined in the direction opposite to that of the shooter 1, and the bottom surface of the lower end (exit side) of the hopper 4 is set to the frame 10. The support plate 52 mounted on the rotatable support bar 30 made of resin provided in the width direction of the hopper 4 and supported on the bottom surface of the hopper 4 on the upper end side (the side that supplies the shellfish) is attached to the first connector 53. Attached to the upper connector 56.
It is attached to. The upper connector 56 is provided above a rotating shaft 55 that is rotatably installed between supporting pieces 54 that are erected so as to face each other in the width direction of the frame 10.

Further, the lower end of the lower connector 57 extending below the rotary shaft 55 is rotatably connected to one end of the second connector 58, and the other end of the second connector 58 is in the width direction of the shooter 1. It is connected to a fixed body 59 provided between the guide rails 40 on both sides. The second connector 58 includes a lower connector 57 and a fixed body 59.
The length can be adjusted by the rotation of the nut 60 in accordance with the length between the lower connector 57 and the fixed body 59 to facilitate the connection.

With such a connecting structure, when the shooter 1 reciprocates in the front-rear direction, the lower connecting member 57 reciprocally rotates about the rotating shaft 55, and accordingly, the upper connecting member 56 and the first connecting member. The child 53 reciprocates in the opposite direction to the shooter 1, and the hopper 4 also reciprocates in the opposite direction to the shooter 1 and reciprocally vibrates in the vertical direction. The shellfish 3 selected by this vibration falls into the box 15 arranged below the tip of each shooter 1.

In all of the hoppers 4 of Examples 1 to 3, the bottom outlets are straight in the width direction, but the bottom outlets of the hopper 4 are located at the widthwise central portions at both widthwise ends as shown in FIG. You may make it dent inward rather than the side. This makes it easier for the shellfish 3 to spread in the width direction of the hopper 4.
Although the bottom outlet of the hopper 4 is linearly recessed in FIG. 9, it may be curved.

[0041]

The automatic shellfish selector according to claim 1 of the present invention has the following effects. ． The shellfish 3 supplied into the hopper 4 is dispersed in the widthwise direction of the hopper 4 by the rectifying body 5, so that the shellfish 3 is transferred to the hopper 4
From the entire widthwise direction, the balls drop on the shooter 1 on average, and the shell 3 flows smoothly on the shooter 1. Therefore, the shellfish 3 almost never overlap and flow, and the sorting accuracy and sorting efficiency are improved. ． Since it is not necessary to manually disperse the shellfish 3 on the shooter 1, the burden on the operator is reduced. ． Since the structure is simple, it is easy to put into practical use and can be manufactured at low cost.

According to the automatic shellfish selector of claim 2 of the present invention,
The shell 3 hits the rectifying body 5 and the flow is dispersed, so that the shell 3 flows smoothly in the hopper 4.

According to the automatic shellfish selector of claim 3 of the present invention,
The shells 3 hit the plurality of rectifying bodies 5 and are more easily dispersed, and since the spaces are provided between the rectifying bodies 5, the flow of the shells 3 is not hindered.

According to the automatic shellfish sorting machine of claim 4 of the present invention,
Since the hopper 4 vibrates, the shellfish 3 supplied into the hopper 4 is dispersed in the hopper 4, and the shellfish 3 flows more smoothly due to the synergistic effect with the dispersion by the rectifying body 5.

In the automatic shellfish sorting machine according to the fifth aspect of the present invention, both the shooter 1 and the hopper 4 can reciprocally vibrate in the feeding direction of the shellfish 3, and can also reciprocally vibrate vertically. However, it does not accumulate in the shooter 1 or the hopper 4, and it easily falls. In particular, the overlapping of the shells 3 in the shooter 1 is reduced, so that the sorting accuracy is improved.
