Hereinafter, with reference to the drawings will be described a rotary roller sorting device (hereinafter referred to as 'selecting device'). In the present invention, the shrimp is set as a sorting article to be sorted and explained. However, the sorting is possible for various articles.

1 is a cross-sectional view showing the structure of a sorting apparatus 1000 according to an embodiment of the present invention.

Referring to FIG. 1, the sorting apparatus 1000 includes a frame, a sorting unit, a driving unit, an input unit, a gap adjusting unit, a water spraying unit, an inclination adjusting unit, a tangle preventing device, a belt conveyor, and the like.

The frame constitutes an external shape of the sorting apparatus 1000, and includes a case 1102 having a space for accommodating the sorting part and the driving part, a bottom plate 1104 forming a lower surface of the case 1102, and sorting. It is made of a wheel 1106 for easy movement of the device 1000, the case 1102 and the bottom plate 1104 is connected by the bottom hinge 1108 is used as a rotating shaft for tilt adjustment.

The case 1102 is generally made of stainless steel, and the space is formed on the side of the case 1102 so as to easily grasp the operating state of the inside from the outside, and to facilitate the internal cleaning. desirable.

Since the sorting unit, the driving unit, the gap adjusting unit, etc. are fixedly installed inside the case 1102, it is made of a rigid structure to withstand shock and vibration well, and a power supply line (not shown) or a water supply pipe for operating the driving unit. (Not shown) has a structure that can be installed.

The sorting part is the most essential part of the present invention, and consists of a pair of sorting rollers 1202 spaced at regular intervals in parallel with each other. The sorting roller 1202 is installed in an inclined state by a predetermined angle, and is rotated in opposite directions by the driving unit.

The sorting roller 1202 pushes up the sorted article sandwiched between the pair of sorting rollers 1202 in the opposite direction to the ground, that is, the circumferential surface adjacent to each other in the pair of sorting rollers 1202 faces upwards. Will rotate. If the adjacent circumferential surface is rotated in the downward direction (the direction pushing down toward the ground), the large sorted article is also cut between the sorting rollers 1202 and the sorted article is damaged. However, when rotated in the opposite direction, the sorting article is slightly lifted from the surface of the sorting roller 1202 under the force to move upward of the sorting roller 1202, and thus the sorting article is caught between the sorting rollers 1202 and damaged. It is eliminated, and the slide down along the inclined state in the state slightly floating on the sorting roller 1202 can be made to move quickly and sorting at the same time. Therefore, when sorting using a pair of sorting roller 1202, the sorted article can be divided into two (large / small).

As described above, although the pair of sorting rollers 1202 constitute the most basic sorting unit, in order to classify the sorted products into three types (large / medium / small), the pair of sorting rollers 1202 should be composed of two layers. . When configuring the sorting roller 1202 in two layers, the interval between the sorting roller 1202 in the upper layer should be greater than the gap between the sorting roller 1202 in the lower layer. Then, the largest sorting article slides along the surface of the upper sorting roller 1202 and falls off at the end, and the second largest sorting article slides along the surface of the lower sorting roller 1202. The smallest sorted article is collected between the bottom sorting roller 1202 and collected at the bottom. At this time, in order to distinguish between the first and the second sorting article, the lower end of the upper sorting roller 1202 is located further horizontally away from the input portion than the lower end of the lower sorting roller 1202, sorting roller 1202 Place it. In other words, the largest sorted items fall farthest, and the smallest sorted goods fall closest so that sorting by size is possible.

2 is a cross-sectional view illustrating a method of sorting a sorted article in the sorting apparatus 1000, and FIG. 3 is a perspective view schematically showing the structure of the sorting unit. Hereinafter will be described taking an example of a representative sorted product shrimp.

As shown in Figure 2 and Figure 3, the shrimp 100 introduced through the input portion falls between the sorting roller 1202 of the sorting portion. Where the shrimp 100 falls is the upper end of the sorting roller 1202 inclined at a certain angle, the shrimp 100 is slid downward along the surface of the sorting roller 1202.

The water spray unit sprays water onto the surface of the sorting roller 1202 so that the shrimp 100 can slide down smoothly without damaging the fish.

The pair of sorting roller 1202 is rotated in the opposite direction, if the sorting roller 1202 is not rotating, the shrimp 100 may not move well can be stagnant. Therefore, when the sorting roller 1202 rotates at a high speed and pushes up the shrimp 100 little by little, the shrimp 100 can move more smoothly.

The sorting roller 1202 should rotate in a direction capable of pushing the shrimp 100 upward. That is, the adjacent circumferential surface of the pair of sorting rollers 1202 should be the direction moving in the opposite direction with respect to the ground. In other words, the shrimp sandwiched between the sorting roller 1202 should be able to move in a direction opposite to the ground rather than toward the ground. If rotating the sorting roller 1202 so that the shrimp 100 moves downward, the shrimp 100 may be damaged while the shrimp 100 is interposed between the sorting rollers 1202, so that the shrimp 100 may not function as a sorting machine. Therefore, the sorting roller 1202 rotates in the opposite direction to push up the shrimp 100 slightly upward, and the shrimp 100 slides downward while being slightly floating from the surface of the sorting roller 1202. Is to come.

On the other hand, as shown in Figure 3, the sorting roller 1202a located in the upper layer and the sorting roller 1202b located in the lower layer is spaced apart from each other. That is, the interval between the upper sorting rollers 1202a is larger than the interval of the lower sorting rollers 1202b. Therefore, the shrimp 100 having a thickness greater than the gap between the upper sorting roller 1202a does not fall between the upper sorting rollers 1202a and slips down to fall from the lower end. And the shrimp 100 having a thickness smaller than the interval between the upper sorting roller 1202a is dropped between the upper sorting roller 1202a and falls to the surface of the lower sorting roller 1202b. If the thickness of the fallen shrimp 100 is larger than the interval between the lower sorting rollers 1202b, the lower sorting roller 1202b does not fall between the slides and falls from the lower end, and if the thickness is small, the lower sorting rollers 1202b. They fall in between and fall to the bottom. Therefore, it is possible to sort the shrimp 100 in three stages (large / medium / small) using a two-layer sorting roller 1202.

In order to sort the shrimp 100 by size, the shrimp 100 should be dropped at different positions. For this purpose, the positions of the lower ends of the sorting roller 1202 are different from each other. That is, the lower end of the upper sorting roller 1202a is positioned farther than the lower end of the lower sorting roller 1202b. The farther place here means that the end of the sorting roller 1202 should be located far more in the horizontal direction than the vertical bottom of the input portion into which the shrimp 100 is introduced. By doing so, the shrimp 100 having a larger thickness falls further in the horizontal direction from the input portion and falls, and the shrimp 100 having a smaller thickness falls closer to each other, thereby accurately selecting size by size.

Shrimp 100 small enough to fall directly between the upper and lower sorting rollers 1202a and 1202b can be gathered in one place using a belt conveyor installed under the lower sorting roller 1202b. This is because the small shrimp 100 may fall to the inlet portion of the sorting roller 1202, but may fall after progressing by a certain distance, and a belt conveyor is used to collect the shrimp 100 fallen in a large area in one place. . However, the belt conveyor is only one example for the practice of the present invention, but is not an absolute configuration, and may form a smooth inclined surface so that the shrimp 100 naturally slides down.

If the sorting roller 1202 is installed in three or four layers and the gap between the sorting rollers 1202 becomes narrower toward the bottom, the shrimp 100 may be sorted to a much larger size. In this case as well, it is preferable that the lower end of the sorting roller 1202 on the uppermost floor is located farthest in the horizontal direction from the input portion.

The guide plate 1206 is provided on the sorting roller 1202.

The guide plate 1206 serves to guide the shrimp so that the shrimp 100 can be accurately entered between the pair of sorting rollers 1202.

4 is a perspective view showing the structure of the guide plate, and shows the installation state of the guide plate 1206 and the sorting roller 1202.

In order to sort large quantities at once, a plurality of sorting units must be installed in parallel. That is, a plurality of sorting rollers 1202 rotating in opposite directions to each other in the horizontal direction are installed, and the first sorting unit S1, the second sorting unit S2, and the third sorting shown in FIG. The part S3 is a sorting part which all have the same component.

In the case where multiple selection units are installed as shown in FIG. 4, the first-second sorting roller 1202-2 included in the first sorting unit S1 and the second-first sorting roller included in the second sorting unit S2 ( 1202-3 is rotating so that the adjacent circumferential surface may face the ground. Shrimp 100 entered between the 1-2 sorting roller 1202-2 and the 2-1 sorting roller 1202-3 during the sorting process has two sorting rollers 1202-2 and 1202- rotating in the ground direction. 3) It can be broken and damaged by being sucked in between. Therefore, it is necessary to block the shrimp 100 from entering between the two sorting rollers 1202-2 and 1202-3. For this purpose, the guide plate 1206 of the '∧' type is the two sorting rollers 1202-2. , 1202-3).

Similarly, the guide plate 1206 of the same type is installed between the 2-2 sorting roller 1202-4 and the 3-1 sorting roller 1202-5 to prevent damage to the shrimp 100. However, the installation of the guide plate 1206 is an optional matter. In the case where only one pair of the sorting rollers 1202 are used, or when selecting a small object such as oyster or shellfish, the guide plate 1206 is not used. Maybe not.

On the other hand, the interval between the selection roller 1202 may be changed by the adjustment of the gap adjusting unit to be described later, when the interval between the selection roller 1202 is different, the interval between the guide plate 1206 should also be different. Since the two plates constituting the guide plate 1206 are rotatably connected by the guide plate hinge 1206a in the middle, the gap between the guide plate 1206 is also adjusted together with the widening or narrowing of the separation roller 1202. Can be.

On the other hand, the guide roller 1204 may be installed on the upper layer of the sorting roller 1202. The guide roller 1204 is for preventing the shrimp 100 from being caught between the sorting roller 1202 and the guide plate 1206 so that the sorting is delayed or the shrimp 100 is damaged.

5A is a cross-sectional view showing a sorting part without a guide roller, and FIG. 5B is a cross-sectional view showing a sorting part with a guide roller. As shown in FIG. 5A, when the sorting unit is composed of the sorting roller 1202 and the guide plate 1206 only, the tail or whisker of the shrimp 100 is sorted by the sorting roller 1202 due to the high speed rotation of the sorting roller 1202. And may be sandwiched between the guide plate 1206. When the shrimp 100 is pinched, the shrimp 100 that has slipped down along the sorting roller 1202 is stagnated, delayed in selection, and more severely, the shrimp 100 may be damaged. Therefore, in order to prevent this, a guide roller 1204 as shown in FIG. 5B is installed between the sorting roller 1202 and the guide plate 1026.

The guide roller 1204 also consists of a pair of rollers, and the spacing between the guide rollers 1204 is considerably larger than the size of the article (shrimp) to be sorted. Therefore, the shrimp (100) falls down with little contact with the surface of the guide roller (1204) and touches the surface of the sorting roller (1202). Even in this state, even if the sorting roller 1202 rotates at a high speed, since the shrimp 100 does not jump over the guide roller 1204 to the guide plate 1206, the shrimp 100 is guide plate 1206. It can prevent getting caught in.

Like the sorting roller 1202, the guide roller 1204 also rotates in opposite directions, but since the distance between each other is much larger than the thickness of the shrimp 100, the sorting action is almost without the shrimp 100 into the sorting part. It only acts to induce entry.

Meanwhile, the driving unit rotates the sorting roller 1202 so that the shrimp 100 can slide smoothly along the surface of the sorting roller 1202. One driving motor 1302 may be connected to each of the sorting rollers 1202 in order to rotate the sorting rollers 1202, and each drive motor 1302 is directly connected to the rotation axis of the sorting roller 1202 in a predetermined direction. The sorting roller 1202 is rotated.

The drive motor 1302 is connected to the selection roller 1202 by a coupling 1304.

FIG. 6 is an exploded perspective view showing the structure of the coupling, and the coupling state of the coupling 1304 will be described with reference to FIG. 6.

The coupling 1304 connected to the driving motor 1302 may include a plurality of stainless rods 1304b inserted into a through hole formed in a stent plate 1304a and a stent plate 1304a to which a rotation axis of the drive motor 1302 is connected. ), A nut 1304c for fixing the stencil 1304c to the stencil plate 1304a, and a rotating plate 1304d in which a plurality of stencil coupling holes 1304e for inserting and fixing the stencil 1304b are formed.

The center of the rotating plate 1304d is connected to the rotating shaft of the sorting roller 1202 to rotate together with the sorting roller 1202.

Therefore, when the driving motor 1302 rotates, the stencil plate 1304a rotates together, and the selection plate 1202 rotates while the rotator plate 1304d rotates together by the stencil 1304b.

The stainless disc 1304a is made of stainless steel or other metal, and the rotating plate 1304d is made of a synthetic resin material such as PP (polypropylene) or PE (polyethylene). In this way, when using a synthetic resin material, noise can be reduced, and stable rotation is enabled by elastic force and restoring force.

In this way, the installation of one drive motor 1302 for each sorting roller 1202 is helpful for stable operation. However, in order to increase the amount of work, if the number of sorting rollers 1202 is increased or a sorting part is formed in multiple layers, There is a problem that the structure is too complicated. In order to solve this problem, it is necessary to apply a method of rotating several sorting rollers 1202 with one driving motor 1302.

FIG. 7 is a cross-sectional view illustrating a connection state between the driving unit and the sorting roller 1202, which will be described with reference to FIG. 7.

Using such a structure, several sorting rollers 1202 located on the same floor can be rotated by using two driving motors 1302. As shown in FIG. 7, when three pairs of sorting rollers 1202 having the same structure are installed, the first sorting roller 1202-1, the third sorting roller 1202-3, and the fifth sorting roller 1202 The rotation direction of -5) and the rotation direction of the second sorting roller 1202-2, the fourth sorting roller 1202-4, and the sixth sorting roller 1202-6 will be reversed. Accordingly, the first sorting roller 1202-1, the third sorting roller 1202-3, and the fifth sorting roller 1202-5 are rotated by the first driving motor 1302a, and the second sorting roller 1208-2. ), If the fourth sorting roller 1208-4 and the sixth sorting roller 1208-6 are rotated by the second driving motor 1302b, the six sorting rollers are all six using the two driving motors 1302a and 1302b. (1202-1, 1202-2, 1202-3, 1202-4, 1202-5, 1202-6) can be rotated.

To this end, the first driving motor 1302a is installed on the rotation shaft of the first sorting roller 1202-1, and the first driving belt 1308a connected to the first sorting roller 1202-1 is connected to the third sorting roller 1202. -3) drive pulley (1306-3). Then, the driving pulley 1306-3 of the third sorting roller 1202-3 and the driving pulley 1306-5 of the fifth sorting roller 1202-5 are connected to the second driving belt 1308b. Then, the first sorting roller 1202-1, the third sorting roller 1202-3, and the fifth sorting roller 1202-5 may rotate in the same direction together with the rotation of the first driving motor 1302a. .

In order to prevent the first driving belt 1308a and the second driving belt 1308b from overlapping each other, the driving pulley 1306-3 to which the first driving belt 1308a and the second driving belt 1308b are connected is doubled. Make it.

Meanwhile, the rotation of the second sorting roller 1202-2, the fourth sorting roller 1202-4, and the sixth sorting roller 1202-6 is also performed in this manner. That is, the second driving motor 1302b is connected to the rotation shaft of the sixth sorting roller 1202-6, and the third driving belt 1308c connected to the sixth sorting roller 1202-6 is connected to the fourth sorting roller 1202. The fourth drive belt 1308d connected to the drive pulley 1306-4 of the -4) to the drive pulley 1306-4 of the fourth sorting roller 1202-4 is connected to the second sorting roller 1202-2. To the drive pulley 1306-2.

When the first driving motor 1302a and the second driving motor 1302b are rotated in opposite directions in the connected state, the first sorting roller 1202-1, the second sorting roller 1202-2, and the third sorting are performed. The roller 1202-3 and the fourth sorting roller 1202-4, the fifth sorting roller 1202-5 and the sixth sorting roller 1202-6 are able to rotate in opposite directions while being in close proximity to each other. .

However, the rotational speeds of the two sorting rollers 1202 constituting one sorting unit need not be the same, and there will be no problem in the sorting action even if the rotational speed of either is larger or smaller.

The driving belt 1308 used in the driving unit may use any one of a timing belt, a flat belt, a V-belt, a round belt, or a chain. Flat belt means that the cross section of the belt is rectangular, V-belt means that the cross section is V-shaped or trapezoidal, round belt means that the cross-section is circular or semi-circular, and the material of the belt may be made of rubber, synthetic resin, textile, etc. will be.

8 is a cross-sectional view illustrating a structure of an input unit, and FIG. 9 is a perspective view illustrating an internal structure of the input hopper 1402, and the input unit of the sorting apparatus 1000 will be described with reference to FIGS. 8 and 9.

The inlet cantilever 1402 is formed in the lower end of the inlet hopper 1402, the conical inlet cover 1404 is installed at a position spaced apart from the inlet 1402a upward by a predetermined distance cantilever from the side of the inlet cover 1404 It consists of a sorting article separator 1406 extending in a shape by a predetermined length.

The input hopper 1402 is manufactured in a funnel shape, and accommodates the shrimp 100, and serves to flow to the sorting unit at the bottom. The inlet 1402a is formed at the lower side or the side of the inlet hopper 1402, and preferably has a size enough to supply the shrimp 100 properly.

The inlet cover 1404 has a conical shape, and prevents the inlet 1402a from being clogged due to too many shrimps 100.

In addition, the sorting article separator 1406 extending from the side of the inlet cover 1404 allows the shrimp 100 to smoothly exit the inlet 1402a. When the shrimp 100 is put on the inlet cover 1404 in the state where the sorting material separator 1406 is installed, a space in which the shrimp 100 is not agglomerated is formed immediately below the sorting material separator 1406, and around the shrimp (100) is stacked. In this state, when the input hopper 1402 is vibrated, the stacked shrimp 100 is supplied to the sorting unit through the inlet 1402a while flowing down little by little. If there is no sorting item separator 1406, since the shrimp 100 is evenly stacked around the inlet 1402a, the shrimp 100 is not easily escaped and is bound together. The sorting article separator 1406 is to prevent such tangling.

The bottom surface of the sorting article separator 1406 is formed with a side plate 1406a extending in a downward direction by a predetermined length. The side plate 1406a serves to block the shrimp from entering the bottom of the sorting separator 1406.

A vibrator 1410 is installed on an outer surface of the input hopper 1402, and the vibration device 1410 transmits vibration to the input hopper 1402. The vibrator 1410 is a device that allows the shrimp 100 accommodated in the inlet hopper 1402 to smoothly escape through the inlet 1402a, and includes a motor 1410a and an eccentric rotating plate 1410b. The eccentric rotating plate 1410b is a rotating plate provided to have a rotation center at a position away from the center of gravity, and generates vibration in the vertical direction with respect to the motor 1410a by the rotation of the motor 1410a.

Meanwhile, the inclination angle may be changed according to the type of sorting article. If the inclination angle is changed, the input unit is also inclined. In general, it is most preferable to keep the input unit in equilibrium with respect to the ground, so that the angle of the input unit also changes according to the change in the angle of the selection unit.

To this end, an input hopper hinge 1412 is rotatably installed at one lower end of the input hopper 1402, and an angle adjustment guide 1414 is installed at the lower end of the input hopper 1402. The bottom of the angle adjustment guide 1414 is fixed to the upper surface of the case 1102. An angle adjustment groove 1416 is formed in the angle adjustment guide 1414, and the input hopper 1402 is fixed to the angle adjustment guide 1414 by a butterfly nut (not shown) that passes through the angle adjustment groove 1416. .

When the angle of the sorting part is changed, loosen the butterfly nut fixed at a certain position of the angle adjusting groove 1416, rotate the feeder by a certain angle around the feeder hopper hinge 1412, the feeder hopper 1402 can be horizontal. Adjust so that
The input hopper 1402 is an essential device when screening fish such as shrimp or anchovies, but when screening objects such as oysters or shellfish, the size of the object is small, and thus the same effect can be achieved without the input hopper 1402. There will be.

10 is a perspective view showing the structure of the gap adjusting unit, with reference to FIG. 10 to explain the operation of the gap adjusting unit.

The pair of sorting rollers 1202 included in the sorting unit rotate in a state spaced apart by a predetermined distance, and the size of the shrimp 100 sorted according to the separation distance between the sorting rollers 1202 is determined. Therefore, if the distance between the sorting roller 1202 can be adjusted is to be selected for the shrimp 100 of various sizes.

The gap adjusting part includes two pairs of bearing housings 1502 fixed to both ends of the pair of sorting rollers 1202. The bearing housing 1502 is provided with a bearing or a bush so that the sorting roller 1202 can freely rotate. In addition, a through hole 1504 is formed in the bearing housing 1502 in a direction perpendicular to the rotation axis of the sorting roller 1202, and an internal thread is formed on an inner wall of the through hole 1504.

The shaft 1506 penetrates through the inside of the through hole 1504, and a male screw 1506a corresponding to the female screw formed on the inner wall of the through hole 1504 is formed at a specific position on the surface of the shaft 1506.

Since the sorting part includes a pair of sorting rollers 1202 by default, if two bearing housings 1502 are installed at both ends of one sorting roller 1202, the pair of sorting rollers 1202 has a total of four bearing housings. 1502 will be installed. In detail, the first bearing housing 1502a is disposed on the upper side (where the shrimp is fed) of the first sorting roller 1202-1 and the second bearing housing 1502b is disposed on the lower side (where the shrimp is discharged). The third bearing housing 1502c is provided at the upper end side of the second sorting roller 1202-2, and the fourth bearing housing 1502d is installed at the lower end side. Therefore, the first bearing housing 1502a and the third bearing housing 1502c are on the inlet side (upper surface of the inclined surface) of the separator, and the second bearing housing 1502b and the fourth bearing housing 1502d are on the outlet side (sloped surface) of the separator. Is located at the bottom of the

Female threads are formed in the through-holes 1504 of the four bearing housings 1502, the rotational direction of the female threads formed in the first bearing housing 1502a and the second bearing housing 1502b, and the third bearing housing 1502c. And the rotational direction of the female thread formed in the fourth bearing housing 1502d are opposite to each other. Therefore, when the shaft 1506 installed through the through hole 1504 rotates in one direction, the two bearing housings 1502 installed in one shaft 1506 move in opposite directions.

The first shaft 1506-1 of the pair of shafts 1506 is installed to penetrate through the bearing housings 1502a and 1502c located at the inlet side of the sorting section, and the second shaft 1506-2 is located at the outlet side of the sorting section. It is installed to penetrate the bearing housing (1502b, 1502d) located.

On the other hand, the male screw 1506a formed on the surface of the shaft 1506 is provided to correspond to the female screw formed in the through hole 1504 of the bearing housing 1502. Therefore, when the shaft 1506 is rotated, the bearing housing 1502 can move in the longitudinal direction of the shaft 1506.

One end of any one pair of shafts 1506 is provided with a rotary knob 1508 to rotate the shaft 1506. In addition, one shaft 1506 and the other shaft 1506 are connected by a synchronization device, so that when one shaft 1506 is rotated, the other shaft 1506 also rotates in the same direction and speed.

The synchronization device of the gap adjuster may use a pulley and a synchronization belt, or a worm gear.

11A and 11B are perspective views showing the configuration of a synchronization device of the gap adjusting unit. FIG. 11A shows a case of using a pulley, and FIG. 11B shows a case of using a worm gear.

In the case of using a pulley, one shaft pulley 1512 is installed at one end of the two shafts 1506, and the two shaft pulleys 1512 are connected to each other using the synchronization belt 1514.

In the case of using the worm 1518 gear, worm wheels 1516 may be installed one at one end of the two shafts 1506 and a worm 1518 may be installed to connect the two worm wheels 1516 to generate synchronous rotation. .

An operation method of adjusting the interval of the sorting roller 1202 by the gap adjusting unit having such a configuration will be described.

When the rotary knob 1508 is installed at one end of the second shaft 1506-2, when the rotary knob 1508 is rotated in one direction, the first shaft () may be rotated by the synchronization belt 1514 or the worm 1518. 1506-1) rotate together in the same direction and at the same rotational speed.

Since the male screw 1506a of the shaft 1506 and the female screw of the inner wall of the through hole 1504 are engaged with each other, and the bearing housing 1502 is connected to the sorting roller 1202, the bearing housing ( 1502 moves back and forth along the longitudinal direction of the shaft 1506. Since the female threads formed in the first bearing housing 1502a and the second bearing housing 1502b have the same direction of rotation, the first bearing is rotated by the first shaft 1506-1 and the second shaft 1506-2. The housing 1502a and the second bearing housing 1502b move in parallel in the same direction, so that the first sorting roller 1202-1 moves in parallel.

In addition, the second sorting roller 1202-2 also performs parallel movement in the same direction with the third bearing housing 1502c and the fourth bearing housing 1502d through the same process.

Since the female screw directions of the first and second bearing housings 1502a and 1502b and the female screw directions of the third and fourth bearing housings 1502c and 1502d are opposite, the first sorting roller 1202-1 and the second sorting roller ( 1202-2 will move in opposite directions. Accordingly, as the rotation knob 1508 rotates, the first sorting roller 1202-1 and the second sorting roller 1202-2 move in parallel with each other or in a direction away from each other.

As such, the user of the sorting apparatus 1000 may determine the size of the shrimp 100 to be sorted by appropriately adjusting the interval between the sorting rollers 1202.

The water spray unit sprays water onto the sorting roller 1202 to allow the shrimp 100 to slide down the surface of the sorting roller 1202. As illustrated in FIG. 1, the water spray unit includes a first spray nozzle 1602a installed at the inlet side of the sorting unit and a second spray nozzle 1602b provided at the outlet side.

Water sprayed from the first spray nozzle 1602a flows down the inclined surface of the sorting roller 1202, so that most of the surface of the sorting roller 1202 can be wetted, but the sorting roller 1202 is rotated due to the rotation of the sorting roller 1202. In case the water does not reach the end of the) to install another injection nozzle (1602b) on the outlet side.

In addition, a third injection nozzle may be installed in the middle of the selection unit.

On the other hand, Figure 12 is a front view showing the structure of the inclination adjustment unit, it will be described with reference to FIG.

As the inclination control unit adjusts the inclination of the sorting roller 1202 included in the sorting unit, since the moving speed or sorting accuracy of the shrimp 100 may vary according to the inclination of the sorting roller 1202, find the most preferable inclination angle. There is a need. As a result of operating the sorting apparatus 1000, the angle of 15 ° to 20 ° is most suitable for sorting fish (mackerel, anchovies, shrimp, etc.), but the outside is kept like shellfish (shellfish, abalone, oyster, etc.). If it is hard, an angle of about 10 ° to 15 ° may be appropriate.

An upper pedestal 1702 is fixedly installed at one lower end of the frame, and an upper pedestal hinge 1702a is rotatably installed at a lower portion of the upper pedestal 1702. In addition, a pair of upper arms 1704 is rotatably connected to the lower portion of the upper support hinge 1702a.

The other end of the upper arm 1704 is connected to the upper end of the hinge shaft 1706 rotatably coupled, and the lower end of the hinge axis 1706 is coupled to the lower arm 1708 rotatably. At the other end of the lower arm 1708, the lower support 1710 is rotatably coupled to the bottom plate 1104 by a lower support hinge 1710a. The upper arm 1704 and the lower arm 1708 generally have a rhombic shape.

The lead screw 1712 is screwed through the pair of hinge shafts 1706, and a handle 1714 is installed at one end of the lead screw 1712.

This configuration is similar to a jack used to lift an automobile or a mechanical device. When the lead screw 1712 is rotated by rotating the handle 1714, a pair of hinge shafts 1706 move upward or away from each other. The arm 1704 and the lower arm 1708 are folded, thus changing the inclination angle of the sorting unit while the pedestal 1702 moves up and down.

A bottom hinge 1108 is installed at the other lower end of the frame, so that when the pedestal 1702 is raised or lowered, the frame is rotated around the bottom hinge 1108, and as a result, the inclination of the selector is changed.

FIG. 13A is a front view showing the structure of a tangle preventing apparatus, and FIG. 13B is a front view showing the structure of a sorting apparatus 1000 equipped with a tangle preventing apparatus.

As shown in FIG. 10, the entanglement preventing device prevents tangling of the sorting article while the rotary blade 1804 mounted on the rotary blade shaft 1802 rotates.

The rotary blade drive belt 1806 is connected by a pulley to rotate the rotary blade shaft 1802. The rotary wing drive belt 1806 is connected to the motor 1902 of the belt conveyor to be described later to obtain a driving force.

The rotary blade shaft 1802 is provided on the upper side of the guide roller 1204 in a direction parallel to the ground and perpendicular to the traveling direction of the sorted article. In addition, the rotary blade 1804 installed on the rotary blade shaft 1802 rotates in a direction opposite to the traveling direction of the sorted article. In other words, the end of the rotary blade 1804 pushes the upper portion of the shrimp 100 coming down along the surface of the sorting roller 1202 serves to push the shrimp 100 in the opposite direction to the sliding direction.

The end of the rotary blade 1804 has a length enough to be spaced apart from the surface of the sorting roller 1202 located in the top layer by a predetermined distance. Therefore, due to the rotation of the rotary blade 1804 does not touch the surface of the sorting roller (1202), the surface of the sorting roller (1202) is pushed in the opposite direction to agglomerate on the surface of the sorting rollers.

When the shrimp 100 is stacked above a predetermined height from the surface of the sorting roller 1202, the shrimp 100 does not fall between the pair of sorting rollers 1202, and thus the accurate sorting is not performed. Therefore, to prevent the tangle is to serve to evenly spread the shrimp (100) that are stuck together.

If the shrimp (100) is not agglomerated and evenly distributed state because it is not piled up high will not pass over the end of the rotary wing (1804), if it is agglomerated shrimp (100) close to the surface of the sorting roller (1202) Bay is passed and the shrimp (100) stacked above a certain height is moved in the input direction again. Shrimp 100 is returned by the rotary blade 1804 once again descends on the surface of the sorting roller 1202 is accurate sorting is made.

Rotating wing 1804 is preferably to use a soft material so as not to damage or damage the sorted article, silicon or PP (polypropylene), PE (polyethylene), etc. may be used, a brush, not a plate-like wing is used Could be

On the other hand, as described above, the belt conveyor serves to move the small shrimp (100) dropped to the outlet down. The belt conveyor consists of a motor 1902, a rotating pulley 1904, a conveying belt 1906, etc., and thus a general conveyor used for moving fruit, aquatic products, construction materials, etc. will be omitted. .

In the case of using a belt conveyor, the structure of the lower part of the sorting apparatus 1000 may be complicated. Therefore, a sliding plate (not shown) may be installed in place of the belt conveyor, and vibration may be applied to the sliding plate to make the sorting article slip well. There will be.

The motor 1902 used in the belt conveyor is located at the lower end of the frame, and rotates the rotary blade shaft 1802 included in the anti-entanglement device while rotating the rotary pulley 1904.

On the other hand, in order to accurately adjust the interval between the sorting roller 1202 may be added a position indicator 1510 that displays the horizontal moving distance of the sorting roller 1202. The position indicator accurately calculates and displays the actual distance traveled by the sorting roller 1202 in consideration of the pitch of the screws formed on the shaft 1506 and the bearing housing 1502 and the rotation speed of the gap adjusting part rotation knob 1508.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and the rights of the person skilled in the art can be easily modified.

In the present invention, the pair of sorting rollers 1202 included in the sorting unit are described as rotating in opposite directions, but the two sorting rollers 1202 may have a similar effect even if they rotate in the same direction.

In the conventional sorting apparatus, since the Laura rotates in the same direction, the sorting article is moved in one direction, thereby lowering the sorting efficiency.

However, as in the present invention, provided with a plurality of sorting rollers 1202 rotating in the same direction, and installing the guide plate 1206 on the upper portion of the sorting roller 1202, the sorting article is prevented from being oriented in one direction Since it can be used as a sorting device will be possible.

According to the present invention there is an effect that can quickly and quickly select the sorted products such as shrimp, fish, shellfish by size.

In addition, according to the present invention can be easily adjusted the interval between the rollers, there is an effect that can accurately set the size of the sorted article.
