The present invention relates to a rotating roller sorting device, and more particularly, to a rotating roller sorting device for sorting the sorted article by size using a roller spaced at a predetermined interval and inclined by a predetermined angle.

An example of such a sorting device is Korean Patent No. 10-0642077, which is filed and patented by the present applicant. In this prior art, a coupling medium is connected to one end of a sorting roller on which a driving motor is rotating. As a direct integrally fixedly coupled as a direct rotation of the sorting roller, or installed on one side of any one of the sorting roller has been proposed a method of integrally rotating a plurality of the sorting roller.

In this prior art, a motor must be directly attached to one end of all the rollers, and in a motor that is floated in the air without a certain support point,

In order to install a motor of the proper capacity, the weight of the motor is excessive, so that it may sag to the lower side, and serious problems may occur in maintaining the straightness with the sorting roller.

If a small motor is installed, not only the desired torque can be obtained, but also the small motor will be vulnerable to moisture and moisture due to its simple configuration, which will cause problems in the durability of the motor.

In addition, in the prior art, in order to rotate the plurality of the sorting rollers integrally, a plurality of layers should be formed in order to prevent the plurality of pulleys and the plurality of belts from overlapping each other, and the pulley, which is powered, is transferred to another pulley. Because of the structure that needs to transfer power again, the number of pulleys becomes too large, the length of the shaft supporting the pulley becomes too complicated, and when the small pulley and the small belt are used, the entire power transmission system Due to its structural weakness, there was a problem of insufficient durability to operate the machine for a long time.

The present invention has been made to solve the above problems,

It is possible to operate, and maintenance is effective,

 A pair of sorting rollers can be rotated in different directions, so that the efficiency of the sorting unit can be increased while the mechanical device is simplified.

Hereinafter, with reference to the drawings will be described a rotary roller sorting device (hereinafter referred to as 'selecting device').

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 10, a sorting unit 20, a driving unit 30, an input unit 40, a gap adjusting unit 50, a water spraying unit 60, and an inclination. The adjusting unit 70, the discharge unit 80 and the like.

Briefly describing this configuration,

The sorting section 20 is composed of at least one pair of sorting rollers 21, which sorting section 20 is placed in the frame 10.

The sorting rollers 21 are rotated while being inclined by a predetermined angle, and at the same time, since a water film is formed on the circumferential surface by the water spraying unit 60, the sorting rollers 21 are placed on top of the pair of sorting rollers 21. The sorted article introduced through the portion 40 naturally proceeds toward the downward (outlet) outlet 80, and the inclination of the sorting roller 21 can be freely adjusted by the inclination adjusting unit 70.

At this time, the sorting unit 20 may be formed in a multi-layer, the lower end of the sorting roller 21 located in the upper layer is located farther in the horizontal direction than the lower end of the sorting roller 21 located in the lower layer, The interval between the pair of sorting rollers 21 located in the upper layer is greater than the gap between the pair of sorting rollers 21 located in the lower layer, the multi-layer sorting unit 20 is horizontal It can be installed in plural.

In addition, the interval between the pair of sorting rollers 21 may be adjusted by the gap between the sorting rollers 21 is opened by the gap adjusting unit 50, these sorting rollers 21 are driven by the drive unit 30 Drives rotation by power transmission.

To explain this configuration in detail,

The frame 10 constitutes an external shape of the sorting apparatus 1000, and includes a case 11 having a space for accommodating the sorting unit and a driving unit, and a support 12 forming a lower surface of the case 11. ), Made of a wheel 13 for easy movement of the sorting device 1000, the case 11 and the support 12 is connected by the bottom hinge 14 is used as a rotating shaft for tilt adjustment.

The case 11 is generally made of stainless steel, and the space is formed on the side of the case 11 to facilitate the internal cleaning at the same time to easily grasp the operating state of the inside from the outside. It is preferable.

Since the sorting unit 20, the driving unit 30, and the space adjusting unit 50 are disposed inside the case 11, the power supply line for operating the driving unit is made of a rigid structure to withstand shock or vibration. Not shown) or a water supply pipe (not shown) may be installed.

The sorting unit 20 is composed of a pair of sorting rollers 21 separated by a predetermined interval in a state parallel to each other. The sorting roller 21 is installed in an inclined state by a predetermined angle, and is rotated in opposite directions by the driving unit 30.

The sorting roller 21 pushes the sorted article sandwiched between the pair of sorting rollers 21 in the opposite direction to the ground, that is, the circumferential surfaces adjacent to each other in the pair of sorting rollers 21 face upwards. Direction of rotation. If the adjacent circumferential surface is rotated in the downward direction (sliding direction toward the ground), the large sorted article is also interrupted between the sorting rollers 21 and the sorted article is damaged. However, when rotating in the opposite direction, the sorting article is slightly lifted from the surface of the sorting roller 21 by the force to move upward of the sorting roller 21, and thus the sorting article is caught between the sorting rollers 21 and damaged. It is eliminated, and the slide down along the inclined state in the state slightly floating on the sorting roller 21 can be made to move quickly and sorting at the same time. Therefore, when sorting by using a pair of sorting roller 21, the sorted article can be divided into two (large / small).

As described above, although the pair of sorting rollers 21 constitute the most basic sorting unit, in order to classify the sorted products into three types (large / medium / small), the pair of sorting rollers 21 should be composed of two layers. . When configuring the sorting roller 21 in two layers, the interval between the sorting roller 21 in the upper layer should be larger than the gap between the sorting roller 21 in the lower layer. Then, the largest sorting article slides along the surface of the upper sorting roller 21 and falls off at the end, and the second largest sorting article slides along the surface of the lower sorting roller 21. And the smallest sorted article is collected between the bottom sorting roller 21 is separated from the bottom. At this time, the lower end of the upper sorting roller 21 is located farther horizontally from the feeder than the lower end of the lower sorting roller 21 in order to separate and separate the first and second sorting articles. 21). 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, a description will be given taking the fish 100 as a representative sorted article as an example.

As shown in Figure 2 and 3, the fish 100 introduced through the input unit 40 falls between the sorting roller 21 of the selection unit. Where the fish 100 falls is the upper end of the sorting roller 21 inclined at a predetermined angle, the fish 100 slides down along the surface of the sorting roller 21.

The water spray unit sprays water on the surface of the sorting roller 21 so that the fish 100 can slide down smoothly without damaging the fish.

The pair of sorting roller 21 is rotated in the opposite direction, if the sorting roller 21 is not rotating, the fish 100 may not be able to move well can be stagnant. Therefore, when the sorting roller 21 rotates at high speed and pushes up the fish 100 little by little, the fish 100 can move more smoothly.

The sorting roller 21 should rotate in a direction capable of pushing the fish 100 upward. That is, the adjacent circumferential surface of the pair of sorting rollers 21 should be in a direction moving in the opposite direction with respect to the ground. In other words, the fish caught between the sorting rollers 21 should be able to move in a direction opposite to the ground, not in the direction toward the ground. If the fish 100 rotates the sorting roller 21 so that the fish 100 moves downward, the fish 100 may be damaged while being interposed between the sorting rollers 21, thereby preventing its function as a sorter. Therefore, as the sorting roller 21 rotates in the opposite direction, the fish 100 is slightly pushed upwards, and the fish 100 slides downward while being finely floated from the surface of the sorting roller 21. Is to come.

On the other hand, as shown in Figure 3, the sorting roller 21a located in the upper layer and the sorting roller 21b located in the middle layer is spaced apart from each other. That is, the space | interval between the upper layer sorting roller 21a is larger than the space | interval of the middle layer sorting roller 21b. Therefore, the fish 100 having a thickness larger than the distance between the upper sorting rollers 21a does not fall between the upper sorting rollers 21a and slides down to fall from the lower end. And the fish 100 having a thickness smaller than the gap between the upper sorting roller 21a is dropped between the upper sorting roller 21a and falls to the surface of the middle sorting roller 21b. If the thickness of the fish 100 is greater than the distance between the middle layer sorting roller 21b, the fish fall off between the middle layer sorting roller 21b and slip off the lower end, and when the thickness is small, the middle layer sorting roller 21b. It falls in between and falls to the lower sorting roller 21c.

The small fish 100 passing between the upper sorting roller 21a and the middle sorting roller 21b reaches the lower sorting roller 21c and then has a smaller fish than the gap between the rollers formed by the lower sorting roller 21c. (100) are distinguished by falling to the lower end of the lower sorting roller (21c), fish larger than the interval between the rollers formed by the lower sorting roller (21c) does not fall between the lower sorting roller (21c) slipping. It comes down and falls off the bottom end.

Therefore, the fish 100 can be sorted in four stages (large / medium 1 / medium 2 / small) using the three-layered sorting roller 21.

In order to easily sort the fish 100 by size, it is necessary to drop the fish 100 at different positions. For this purpose, the positions of the lower ends of the sorting roller 21 are different from each other. That is, the lower end of the upper sorting roller 21a is located farther than the lower end of the middle sorting roller 21b, and the lower end of the middle sorting roller 21b is the lower end of the lower sorting roller 21c. Place it farther than the end.

 The farther here means that the end of the sorting roller 21 should be located farther in the horizontal direction than the vertical lower end of the input portion 40 to which the fish 100 is introduced. By doing so, the fish 100 having a larger thickness falls further in the horizontal direction from the input portion 40 and falls away, and the fish 100 having a smaller thickness falls close to each other, thereby making accurate selection by size. will be.

If the sorting roller 21 is installed in four or five layers and the gap between the sorting rollers 21 becomes narrower toward the bottom, the fish 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 21 on the uppermost floor is located farthest in the horizontal direction from the feeding part.

The guide plate 22 is provided on the sorting roller 21.

In the present invention, it is described that the guide plate 22 is installed on the sorting roller 21, but the guide plate 22 may not be installed depending on the type and nature of the sorting article.

The guide plate 22 serves to guide the fish so that the fish 100 can accurately enter between the pair of sorting rollers 21.

In order to sort a large amount at once, a plurality of sorting units 20 should be installed in parallel. That is, it is possible to install a plurality of the pair of sorting roller 21 in the horizontal direction to rotate in the opposite direction to each other.

Meanwhile, the driving unit 30 rotates the sorting roller 21 so that the fish 100 can smoothly slide along the surface of the sorting roller 21.

It is to have a desirable structure to be adjusted.

6 and 7, 7, 8 and 9,

The drive motor 36, all the drive pulleys 33, the idle pulleys 38, and all the bearing housings 32 are fixedly coupled to the drive unit mounting plate 31 as a single drive motor. 36 and one driving belt 37 can drive all the driving pulleys 33 simultaneously, and among the driving pulleys 33, the upper driving pulley 33a to rotate the upper sorting roller 21a and The lower drive pulley 33c to rotate the lower sorting roller 21c of the drive pulleys 33 is positioned on the same vertical line, and the middle sorting roller 21b of the drive pulleys 33 may be rotated. The intermediate layer drive pulley 33b is located further away from the drive motor 36 and the idle pulley 38 so that all the drive pulleys 33 and idle pulleys 38 are driven by the one drive belt 37. Rotate at the same time, but using the one drive belt 37 as a double-sided timing belt If sorting roller 21 of the pair are included in the sorting unit 20 which will be able to rotate at the same time in different directions. That is, by using the one driving belt 37 as a double-sided timing belt,

The pair of sorting roller 21 is to be a preferred structure that can be rotated in the direction in which the adjacent circumferential surface moves in the opposite direction with respect to the ground,

 In addition, the pair of sorting rollers 21 included in the sorting unit 20 will be a preferred structure that can be easily moved during operation for adjusting the interval.

7 is a view showing that the multiple selection unit 20 is rotated simultaneously with one drive motor 36,

FIG. 8 is a view for explaining that when a plurality of multi-layer sorting units 20 are installed in a horizontal direction, each of the multi-layer sorting units 20 is driven by a plurality of drive motors 36.

FIG. 9 illustrates that when the plurality of multi-layer sorting units 20 are installed in a horizontal direction, all of the multi-layer sorting units 20 are driven by only one driving motor 36 and one driving belt 37. It is a figure.

In the present invention, the configuration of the drive belt 37 is described as a timing belt or a double-sided timing belt, but the present invention is not limited thereto.

The drive belt is

Timing belt, flat belt, V belt (V-Belt), round belt (Round-Belt) or any one of the chain can be used, in addition to any power transmission method that satisfies the object of the present invention can be used. something to do.

In addition, the drive motor 36 in this invention may use either an electric motor or a hydraulic motor.

In the present invention, the driving unit mounting plate 31 and the universal joint 35 and the like are used in the method of rotating the pair of sorting rollers 21, but one side end of the sorting rollers 21 is used. Even if the driving unit is formed as a driving hydraulic motor respectively installed in the direct rotation of the sorting roller will be able to satisfy the object of the present invention.

4 and 5 are perspective views illustrating a connection state of the sorting roller 21, the gap adjusting unit 50, and the driving unit 30, and the operation of the gap adjusting unit will be described with reference to FIG.

The pair of sorting rollers 21 included in the sorting unit 20 rotate in a state spaced apart by a predetermined distance, and the size of the fish 100 sorted according to the separation distance between the sorting rollers 21 is determined. Therefore, if the distance between the sorting roller 21 can be adjusted is to be selected for the fish 100 of various sizes.

The gap adjusting unit 50 includes two pairs of bearing housings 51 fixed to both ends of the pair of sorting rollers 21. The bearing housing 51 is provided with a bearing or a bush so that the sorting roller 21 can rotate freely. In addition, a through hole 52 is formed in the bearing housing 51 in a direction perpendicular to the rotation axis of the sorting roller 21, and an internal thread is formed on an inner wall of the through hole 52.

The shaft 53 is configured to penetrate the inside of the through hole 52. Male threads 54a and 54b corresponding to the female screw formed on the inner wall of the through hole 52 are formed at a specific position on the surface of the shaft 53.

Since the sorting unit 20 basically includes a pair of sorting rollers 21, if two bearing housings 51 are installed at both ends of one sorting roller 21, a pair of sorting rollers 21 is provided in total. Two bearing housings 51 will be installed. In detail, the first bearing housing 51a is disposed at the upper end side (where the fish is introduced) of the first sorting roller 21-1, and the second bearing housing 51b is disposed at the lower side (where the fish is discharged). The third bearing housing 51c is provided at the upper end side of the second sorting roller 21-2, and the fourth bearing housing 51d is provided at the lower end side. Therefore, the first bearing housing 51a and the third bearing housing 51c are on the inlet side (upper surface of the inclined surface) of the sorting part, and the second bearing housing 51b and the fourth bearing housing 51d are on the outlet side (sloped surface) of the sorting part. Is located at the bottom of the

The female thread is formed in the through-hole 52 of the four bearing housings 51, and the rotation direction of the female thread formed in the first bearing housing 51a and the second bearing housing 51b, and the third bearing housing 51c. And the rotational directions of the female threads formed in the fourth bearing housing 51d are opposite to each other. Therefore, when the shaft 53 installed through the through hole 52 rotates in one direction, the two bearing housings 51 installed in one shaft 53 move in opposite directions.

Of the pair of shafts 53, the first shaft 53-1 is installed to penetrate the bearing housings 51a and 51c located at the inlet side of the sorting section, and the second shaft 53-2 is the outlet side of the sorting section. It is installed to penetrate the bearing housing (51b, 51d) located in.

On the other hand, the male screw 54a formed on the surface of the shaft 53 is provided to correspond to the female screw formed in the through hole 52 of the bearing housing 51. Therefore, when the shaft 53 is rotated, the bearing housing 51 can move in the longitudinal direction of the shaft 53.

One end of one of the pair of shafts 53 is provided with a rotary knob 55 to rotate the shaft 53. And one shaft 53 and the other shaft 53 is connected by the synchronization device, when rotating one shaft 53, the other shaft 53 also rotates in the same direction and speed.

Here, the through holes 52 are not formed inside the through holes of the first bearing housing 51 a and the second bearing housing 51 b, and no male threads are formed on the surface of the corresponding shaft 54x. When the shaft 53 installed through the shaft rotates in one direction, the two bearing housings 51 installed on one shaft 53 can be spaced apart from each other, but the three-bearing housing 51c and the fourth bearing Only the housing 51d would be able to achieve comparable results.

The synchronization device of the gap adjusting unit may use a pulley 56 and a synchronization bell 57, or a worm gear (not shown) may be used.

In the case of using the pulley 56, one shaft pulley 56 is installed at one end of the two shafts 53, and the two shaft pulleys 56 are connected to each other using the synchronization belt 57.

In the case of using a worm gear, one worm wheel may be installed at one end of the two shafts 53 and a worm connecting two worm wheels may be installed to generate synchronous rotation.

The water spray unit 60 sprays water onto the sorting roller 21 so that the fish 100 slides down the surface of the sorting roller 21.

On the other hand, the inclination control unit 70 is to adjust the inclination of the sorting roller 21 included in the sorting unit, since the moving speed or sorting accuracy of the fish 100 may vary according to the inclination of the sorting roller 21, It is necessary to find the most desirable angle of inclination. As a result of operating the sorting device 1000, the angle of 15 ° to 20 ° is most suitable for sorting fish (mackerel, anchovies, shrimp, etc.) If it is hard, an angle of about 10 ° to 15 ° may be appropriate.

This configuration is similar to a jack used to lift an automobile or a mechanical device, and when the lead screw is rotated by rotating the handle, the pair of hinge shafts fold up or away from each other, and the upper and lower arms are folded. Therefore, since the pedestal moves up and down, the general structure of changing the inclination angle of the sorting unit is omitted.

A bottom hinge 14 is installed at one lower end of the frame 10 so that the frame 10 is rotated around the bottom hinge 14 when the inclined nail cutting portion 70 is adjusted to go up or down. The inclination of the sorting unit 20 is changed.

On the other hand, in order to accurately adjust the distance between the sorting rollers 21 may be added a position indicator (not shown) for displaying the horizontal moving distance of the sorting rollers 21. The position indicator accurately calculates the distance actually moved by the sorting roller 21 in consideration of the pitch of the screws formed on the shaft 53 and the bearing housing 51 and the rotation speed of the rotation knob 55 of the gap adjusting part 50. Display.

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 21 included in the sorting unit has been described as rotating in opposite directions, but when the two sorting rollers 21 rotate in the same direction, similar effects can be obtained.

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 21 to rotate in the same direction, and installing the guide plate 22 on the upper portion of the sorting roller 21, to prevent the sorting article is oriented in one direction Because it can be used as a sorting device will be possible.
