CONSTITUTION:When shellfishes are classified, a large number of axial wires 1, 2 fixed to annular flanges 3, 4 at both end parts thereof and cylindrically arranged so that the intervals between the axial wires 1, 2 are set considering the classifying sizes of the shellfishes 5 and a large number of annular wires subjected to bending molding are arranged to the inside and outside of the axial wires 1, 2 at predetermined intervals considering the classifying sizes of the shellfishes and the crossing parts with the axial wires 1, 2 of the annular wires are welded to constitute a unit cylinder 8. A plurality of unit cylinders 8a-8d different in interval size are connected in series so that the interval sizes successively become a large size from a small size to constitute a connected cylinder 10. This connected cylinder 10 is obliquely arranged and the shellfishes 5 are charged in the connected cylinder 10 from a chute 20 while the connected cylinder 10 is rotated by driving by driving a motor 15 and classified in the transfer process of the shellfishes 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article selecting device for selecting clams, clams, fruits and other articles having substantially similar outer shapes according to size.

[0002]

2. Description of the Related Art Conventionally, shellfish and the like are manually sorted by size. There has also been an attempt to use a sorting cylinder in which a large number of axis lines are aligned in the axial direction at predetermined intervals along the circumference of a predetermined diameter.

[0003]

The conventional manual selection not only causes heavy labor for workers, but also it is difficult to improve the efficiency and requires skill and experience to improve the selection accuracy. I got it.

Further, the sorting cylinder determines the size of the article by the gap between the parallel axes arranged in a cylindrical shape. Therefore, the article slides along the axis without passing through the gap, or passes through while being sandwiched in the gap. There was a risk that it would be impossible.

[0005]

According to the present invention, however, every other axial line is arranged inside and outside along the inner and outer double circles, and the annular line in the circumferential direction is bent alternately on the inner and outer axis lines. By doing so, it becomes possible to sort the articles while appropriately stirring them, and the above-mentioned conventional problems are solved.

That is, according to the present invention, the peripheral wall is provided with a gap through which articles of a predetermined size can pass, and the peripheral wall is formed with a unit cylinder of a predetermined length having a continuous concavo-convex shape, and a plurality of the unit cylinders are formed. The article sorting apparatus is characterized in that the article is connected to form a connection tube such that the size of the gap through which the articles can pass is gradually increased to a larger size, and the connection tube is rotatably installed obliquely. According to another aspect of the present invention, each axis is arranged along the inner and outer double circumferences at intervals such that articles of a predetermined size can pass in and out every other one, and articles of a predetermined size can pass in the circumferential direction. The unit cylinders are configured by mounting annular wires at intervals, and a plurality of the unit cylinders are connected to form a connecting cylinder such that the size of the gap through which the article can pass is gradually increased to a large size. It is an article sorting device characterized by being installed rotatably obliquely. Next, in another invention, the number of unit cylinders of the connecting cylinder is set to 3 to 6, one side of the connecting cylinder supports the outer wall of the connecting cylinder by a roller, and the other side thereof is a drive shaft connected to the connecting cylinder. It is rotatably supported by a shaft and installed diagonally.

In the sorting apparatus of the present invention, the articles are supplied to one of the connecting cylinders by the chute, and the sorted articles are appropriately dropped by their own weight into the container. In this case, if the connecting cylinder is rotated, the article moves in the circumferential direction and moves from the high side to the low side. The inclination angle of the connecting tube is, for example, 3 to 10 degrees. The diameter of the unit cylinder is not particularly limited, but the diameter of 150 mm to 400 mm is most commonly used.

The rotation speed of the connecting cylinder is 5 rpm to 20 rpm.
The length of the unit cylinder is preferably 200 mm to 500 mm.

The material of the unit cylinder is preferably one having characteristics such as rust resistance, toughness, rigidity and deformation resistance. For example, a material composed of a stainless wire or a steel wire coated with a synthetic resin is also conceivable. By further devising the structure, a synthetic resin molded product can be adopted.

The number of connected unit tubes varies depending on the type of article and the number of selection stages, but in the case of clams and other shellfish, usually 3 to 5 are suitable.

The sorting apparatus of the present invention can be widely used for shellfish, fruits, agricultural products and the like.

[0012]

According to the present invention, since the wall of the unit cylinder is formed into a concavo-convex shape which is continuous inside and outside, the article is inevitably agitated (or inverted) by the concavo-convex shape when the unit cylinder is slowly rotated. It can fall into the gap relatively easily and pass through it depending on its size.

Since the movement of the article is due to its own weight effect accompanied by the change of the position of the article, there is no fear that an excessive external force is applied to the article in combination with the slow rotation of the unit cylinder, and the article is forcibly moved to the uneven gap. There is no danger of being pushed into.

[0014]

Example 1 Stainless steel axes 1 and 2 are alternately arranged in parallel on inner and outer concentric circles at predetermined intervals, and both ends thereof are fixed to annular collars 3 and 4. Since the gap between the axes 1 and 2 is a gap through which the shellfish 5 can pass, it is regulated so as to match the desired sorting size.

Ring wires 6 and 6 formed by bending a stainless steel wire inside and outside the axis lines 1 and 2 are fitted at intervals allowing the shell 5 to pass therethrough, and a crossing portion 7 between the axis lines 1 and 2 and the ring wires 6 and 6 is fitted. The unit tube 8 is formed by welding and fixing. A receiving flange 9 having a predetermined width is provided on one outer edge of the annular flange 3 to form a roller receiving portion.

On the inner circumferences of the annular collars 3 and 4, the axis lines 1 and 2 are provided.
Axis support portions 3a and 3b are provided to support the
The ends of the axes 1 and 2 are supported and fixed by welding.

The unit tubes 8a, 8b, 8c, 8d having different gap sizes of the unit tube 8 are sequentially connected in series from a unit tube having a small gap size to a unit tube having a large gap size.
0, a unit cylinder 8a having a receiving flange 9 is arranged at one end (left end in FIG. 1) of the connecting cylinder 10, and an annular flange 4 is provided at the other end unit cylinder 8d.
The drive plate 13 with the drive shaft 12 is connected to the drive shaft 12 via the connecting member 11, and the pulley 14 is fixed to the drive shaft 12.
The belt 17 is attached to the pulley 16 of the motor 15 and the connecting cylinder 10 is erected at a gentle inclination of about 5 degrees by the roller 18 and the bearing 19 of the drive shaft 12.

In the above embodiment, one side (the left end in FIG. 1)
When the motor 15 is started and the connecting cylinder 10 is rotated at 10 rpm while supplying a fixed amount of the shellfish 5 through the chute 20 from the shell 20, the shellfish 5 is moved from the gap of the axis lines 1 and 2 according to the size to the arrow 2
1 falls into the receiver 22 containing water. Since the four unit cylinders 8a, 8b, 8c and 8d are connected in the above embodiment,
It is sorted into 4 sizes. In the figure, 29 is a water level and 30 is a partition plate.

If water is sprinkled from inside or outside the connecting cylinder 10 in the selection, the shellfish can be relaxed and the passage through the gap can be made smoother. It is also possible to remove mud and other foreign matter attached to the shell. In FIG. 2, the shellfish enters the gap at the position a, completely passes at the position b, and the remaining shellfish slides at the position c and moves to the lower side.

In the above, the diameter is 200 mm and the length is 400 mm.
When the clams were selected using the connecting cylinder in which four unit cylinders were connected, 1 ton could be selected in one hour. This ability was equivalent to the ability of several workers, and the sorting accuracy was extremely good.

[0021]

[Embodiment 2] Bending lines 23 having a predetermined length are arranged side by side at predetermined intervals, and axes 24 and 25 are arranged at the bending portions of the bending lines 23 and welded and fixed to form a mesh plate 28 (FIG. 5). This mesh plate 2
A unit cylinder 27 is formed by winding 8 in a cylindrical shape and fixing both ends of the axes 24 and 25 to the annular collar 26.

Although the above is an example of the manufacturing method, the mesh plate 28 may be formed by molding a synthetic resin.

When the mesh plate 28 and the annular brim 26 are made of steel, it is preferable that after the unit cylinder is formed, it is dip-coated with a synthetic resin solution (for example, vinyl chloride or the like) and subjected to rust resistance treatment.

The method of use, operation, and effect of the above-mentioned connecting device using the connecting cylinder are the same as those of the first embodiment, and the description thereof will be omitted.

[0025]

As described above, according to the present invention, the peripheral wall of the unit cylinder is formed in a concavo-convex shape. Therefore, if this is slowly rotated, the articles can be selected while being stirred. Therefore, there is no risk of an unreasonable external force being applied, and automatic sorting can be performed by its own weight, so that there is no risk of damage to the articles or stoppage due to pinching.
