[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor apparatus having means for uniformly spreading small fish such as shirasu fish on a conveyor belt in the process of being transported by a conveyor.

[0002]

2. Description of the Related Art Generally, in a so-called "boiled and dried" manufacturing process in which small fish such as shirasu fish are boiled, dried and dried, the boiled small fish are spread on a conveyer, and this is separated into the next sorting process. To eliminate small fish such as small crabs and shrimp, and evenly select the size of the dried fish.

[0003]

In recent years, the sorting operation has been automatically performed. However, in order to efficiently perform the sorting operation, it is necessary to uniformly spread the boiled to be sent to the sorting machine on a conveyor belt. However, there is a problem that the accuracy and efficiency of the sorting are reduced due to the boiled or sparse boiled dried cakes in the sorting process. In addition, since there was no simple means for solving such a problem, there was an inconvenience in that the boiled dried vegetables on the conveyor had to be manually spread using a leveling plate.

[0004]

In order to solve the above-mentioned problems, a small fish conveyor apparatus is provided with a deflecting rotor traversing above a conveyor belt for transporting the small fish, and the deflecting rotor is moved from a rotating shaft and its outer peripheral surface. deflector plate having collision set the radial direction
And driving the deflecting rotor by driving means for rotating the deflecting rotor in a direction opposite to the conveying direction of the conveying conveyor, and simultaneously moving the deflecting plate provided on the deflecting rotor to the conveying conveyor.
It is provided to be inclined with respect to the feeding direction . Therefore
The deflecting plate is substantially shaped so that its planar shape is located on the rear side in the rotational direction on both axial ends relative to the center of the deflecting rotor .
Preferably, the Ru is bent to shape. It is preferable that a second deflecting rotor is provided adjacent to the rear of the deflecting rotor, and one end of the deflecting rotor is displaced from the other end in a direction opposite to a conveying direction of the conveyor. It is also preferable that the peripheral speed at the tip of the deflecting plate is set faster than the transport speed of the transport conveyor. Further, an adjusting means for adjusting the minimum distance between the tip of the deflecting plate and the conveyor belt may be provided.

[0005]

The boiled dried noodles are supplied on the conveyor belt in a lump and are conveyed as the conveyor belt moves. When the peak of the dried boil reaches the deflecting rotor and is lower than the distance from the conveyor belt, it passes under the deflecting rotor. When it is high, it is pushed back by the deflection plate of the deflection rotor. Thisゝa, with respect to the moving direction of the deflector conveyor belts, since the substantially inclined, anchovy striking the deflector towards the right and left side portions of the conveyor belt along the polarization direction plate movement Then, the sheet is developed in the width direction of the conveyor belt, and passes through a gap between the conveyer belt and the deflecting plate that rotates while reducing its height. The inclination of the deflecting plate may be formed in a form extending from one side of the conveyor belt to the other side, or may be formed in a substantially rectangular shape extending from both sides to the center or from the center to both sides, but the operation is substantially the same. is there.

If the peripheral speed of the tip of the deflecting plate is made faster than the conveying speed of the conveyor, the small fish is pushed back once in a direction substantially perpendicular to the deflecting plate, and then finally the deflecting plate and the conveyor belt. This push-back, that is, the movement toward the side of the conveyor belt, is repeated before passing through the gap between. Also, by adjusting the minimum distance between the tip of the deflecting plate and the conveyor belt, the amount of the small fish pushed back in a direction substantially perpendicular to the deflecting plate, and thus the small fish is moved in the width direction of the conveyor belt by the deflecting plate. The distance to be adjusted is adjusted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG . 1 and 2 show a first embodiment. In the figure, reference numeral 1 denotes a conveyor device according to the present invention. The conveyor device 1 includes a conveyor 2 for conveying small fish F such as boiled shirasu,
A deflecting rotor 1 for uniformly spreading small fish conveyed in a lump on the conveyor 2 on the conveyor 2
Has zero.

The transport conveyor 2 has two rollers 3, 3 driven by driving means (not shown), and a conveyor belt 4 wound therebetween. The upper surface of the conveyor belt 4 is substantially horizontal, and its width W2 is set to be about three times the width W1 of the small fish F supplied on the conveyor 2 by hand. Reference numerals 5 are guide plates attached to both sides of the conveyor belt 4 to prevent small fish F conveyed on the conveyor belt 4 from falling off the conveyor belt 4.

The deflection rotor 10 includes a rotating shaft 11 and a rotating shaft 1.
1 is composed of four deflection plates 12 erected radially on the outer peripheral surface in the axial direction. The deflecting rotor 10 is disposed horizontally above the conveyor belt 4 with its axis oriented substantially perpendicular to the direction of conveyance of the conveyor 2, and its outer circumferential surface is opposite to the direction of conveyance of the conveyor 2. Rotated to become.

The deflecting plates 12 of the deflecting rotor 10 are flat with respect to the axial direction of the rotating shaft 11 such that both ends of the deflecting plate are located behind the center of the rotating shaft 11 in the rotation direction of the rotating shaft 11. It is bent in a substantially rectangular shape when viewed. The leading edge is set parallel to the upper surface of the conveyor belt 4 so that the minimum distance L between the leading end and the conveyor belt 2 is kept substantially uniform in the axial direction of the rotating shaft 11. The bending angle α is set to about 160 °, but is appropriately changed according to the width W2 of the conveyor belt 4 and the like. The rotating shaft 11 has an adjusting means (not shown) that can adjust the height from the conveyor belt 4 to adjust the minimum distance L between the tip of the deflecting plate 12 and the conveyor belt 4. The rotation speed of the rotating shaft 11 is set such that the peripheral speed at the tip of the deflecting plate 12 is slightly higher than the transfer speed of the transfer conveyor 2, but the change can be arbitrarily performed as necessary.

Next, the operation will be described. The small fish F supplied on the conveyor belt 4 by hand is conveyed toward the right side in the figure on the conveyor 2 in the form of a lump. On the other hand, the rotating shaft 11 is rotated clockwise by driving means (not shown). Of the small fish F conveyed to the deflecting rotor 10, those that cannot pass through the gap between the deflecting plate 12 and the conveyor 2 are deflected by the deflecting plate 12.
2 is pushed back in a direction A substantially perpendicular to the axis 2 and rises upward as indicated by a two-dot chain line in FIG.

Here, the deflecting plate 12 is viewed in a direction perpendicular to the axial direction of the rotating shaft 11 such that both shaft ends are located rearward in the rotating direction of the rotating shaft 11 from the center of the rotating shaft 11. The small fish F pushed back in a direction substantially perpendicular to the deflecting plate 12 moves toward the left and right sides of the conveyor belt 4 along the deflecting plate 12 and is condensed. The small fish F spreads substantially uniformly in the width direction of the conveyor belt 4. The small fish F which has spread substantially uniformly in the width direction of the conveyor belt 4 is conveyed through a gap between the rotating deflecting plate 12 and the conveyor belt 4.

The peripheral speed at the tip of the deflecting plate 12 is
Is set faster than the transport speed of the small fish F,
This pushing back, that is, the movement toward the left and right sides of the conveyor belt 4, after being once pushed back in a direction substantially perpendicular to the deflecting plate 12 and finally passing through the gap between the deflecting plate 12 and the conveyor belt 4. Repeated. As a result, the height of the small fish F conveyed on the conveyor 2 is kept substantially equal to the minimum distance L between the tip of the deflecting plate 12 and the conveyor belt 4, and the small fish F is conveyed on the conveyor 2.
Spread to both sides of the.

The adjustment of the minimum distance L between the tip of the deflecting plate 12 and the conveyor belt 4 is performed by raising and lowering the position of the rotating shaft 11 by adjusting means (not shown). By adjusting the distance L, the amount of the small fish F pushed back in a direction substantially perpendicular to the deflecting plate 12, and thus the deflecting plate 1
2, the distance by which the small fish F moves in the width direction of the conveyor belt 4 can be adjusted. That is, by adjusting the adjusting means in accordance with the transport amount of the small fish F, the small fish F can be evenly spread on the conveyor belt 4 at any transport amount. For example, when the transport amount of the small fish F is small, the interval L may be narrow, and when the transport amount is large, the interval L may be wide.
The small fish F transported to the end of the transport conveyor 2 is sent to the next sorting step.

Next, a second embodiment shown in FIGS. 3 and 4 will be described. The same components and operations as in the first embodiment are denoted by the same reference numerals in the drawings, and description thereof will be omitted. The second embodiment is 2
In this figure, the deflection rotors 10 are arranged in a dogleg shape.
That is, a pair of front and rear rotating shafts 11a and 11b are arranged above the conveyor belt 4. Front rotating shaft 11
In a, the shaft end on the right side in the conveyance direction (lower side in FIG. 3) is deviated in the conveyance direction with respect to the shaft end on the left side in the conveyance direction (upper side in FIG. 3). On the other hand, the rear rotating shaft 11b as the second rotating shaft is 1
Contrary to 1a, the shaft end on the right side in the transport direction (lower side in FIG. 3) is deviated in the direction opposite to the transport direction with respect to the shaft end on the left side in the transport direction (upper side in FIG. 3). The angles β and γ formed by these axes and the perpendicular P perpendicular to the transport direction are each about 2 degrees.
It is set to 0 °. Four deflecting plates 12 are radially protruded from the outer peripheral surfaces of the rotating shafts 11a and 11b substantially in parallel with the axes thereof.

In the second embodiment constructed as described above, the small fish F pushed back on the conveyor belt 4 in the substantially right angle direction on the conveyor belt 4 by the deflecting plate 12 of the front rotating shaft 11a is a deflecting plate. It moves in the B direction along 12. Although some irregularities remain on the surface of the small fish F that has passed through the front rotation shaft 11a, those that cannot pass through the gap between the deflection plate 12 and the conveyor belt 4 of the rear rotation shaft 11b are formed on the deflection plate 12. By being pushed back in a direction substantially perpendicular to the direction and moving in the C direction along the deflecting plate 12, the unevenness of the surface of the small fish F is eliminated, and the small fish F is substantially uniform in the width direction of the conveyor belt 4. It will spread in thickness.

When the angles β and γ formed by the axes of the rotating shafts 11a and 11b and the perpendicular P perpendicular to the conveying direction are increased and the rotating shafts 11a and 11b are greatly inclined with respect to the conveying direction, the small fish F It moves largely in the width direction of the conveyor belt 4. That is, according to the ratio of the width W1 of the conveyed small fish F to the width W2 of the conveyor belt 4, both rotating shafts 11
By adjusting the angle θ between the small fishes a and 11b, the small fish F can be spread substantially uniformly in the width direction of the conveyor belt 4.

The height of the small fish F conveyed to the front rotating shaft 11a is higher than the height of the small fish F conveyed to the rear rotating shaft 11b. Therefore,
By making the minimum distance L between the front end of the deflecting plate 12 and the conveyor belt 4 in the front rotation shaft 11a wider than that in the rear rotation shaft 11b, the front rotation shaft 1
By making the amount of the small fish F pushed back by the deflection plate 12 of 1a equal to that of the rear rotating shaft 11b, the load on the driving means for driving the front rotating shaft 11a can be reduced. Note that this reduces the amount of the small fish F pushed back by the deflecting plate 12 erected on the front rotating shaft 11a, so that the distance in which the small fish F moves in the B direction is shortened. By increasing the size, the small fish F can be sufficiently spread also in the B direction. The present invention can also be used for articles conveyed in a lump other than the small fish F.

[0019]

Effects of the Invention The present invention as described above, by a simple structure that moves toward the small fish to the side of the conveyor belt by the deflection plate to rotate, small fish a conveyor belt that has been transported become nodular There is an effect that it can be easily and uniformly spread on the top.
