BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight sorting apparatus using a plurality of electronic scales,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting apparatus, and more particularly, to an electronic weight sorting apparatus that accurately and quickly selects the weight of fish and shellfish such as abalone.

The background art of the present invention is an electronic weighing machine (Korean Patent No. 10-1555807) in which a sensor conveyor is omitted and an electronic weighing machine in which a sensor conveyor is omitted, which eliminates measurement errors (Korean Patent Application No. 10-2015-0163686 ).

The inventions disclosed in the background art have some problems.

1. Conventional sorting machines, for example conventional abalone sorting machines, are operated on a ship, which is a maritime cage farm. Therefore, when the ship is shaken by roaring and pitching applied to the ship, It is difficult to measure the weight accurately. Especially when the frame containing the abalone for the selection work is taken out of the farm or moved to the ship, the weight is moved to the ship by the upper, lower, left, It is difficult to accurately measure the overturning weight because an irregular impact may be applied. In addition, an electronic balance including a load cell is affected by the sea breeze, making it difficult to accurately measure the weight.

2. After the weighed abalone arrives at the discharge conveyor, when it is discharged by the discharge device, the discharge scraper can not scrape the abalone precisely, and the abalone may fall in the direction of "E" which is the end of the discharge conveyor .

3. Because it is difficult to manufacture the circular bottom plate and the circular rotary plate so as to maintain the exact concentricity and the horizontal, there is a gap where the gap between the bottom surface of the scraper and the upper surface of the circular bottom plate is constant, The tail of a creature such as a shell or an early body is caught in a scraper and reaches a weighing plate, which is likely to cause a measurement failure.

4. Also, the upper surface of the round bottom plate and the weighing plate is a flat and circular circular bottom plate, and the shell of the abalone to be moved on the upper surface of the weighing plate is a curved surface, so that the rolled thrown by the scraper It is probable that it will become a cause of faulty measurement.

5. BACKGROUND ART [0002] A load cell used in the technique of the present invention is very lightweight for 1 kg to 3 kg and can be easily broken by high-pressure water cleaning or external impact.

6. Conventional separator is exposed to the outside, such as air cylinders and solenoid valves, which are discharge systems located under the discharge conveyor, and can easily be corroded or damaged by moisture such as seawater.

That is, according to the present invention, it is possible to accurately determine the weight of the overturned horses by using the results obtained by measuring the weights of the three weighing plates using not only one but several times, for example, three electronic scales, An electronic weight selection device is provided.

In addition, the present invention provides a weight selection device capable of increasing the accuracy of the electronic balance by preventing the instrument panel including the load cell from being affected by the wind.

That is, all the surfaces surrounding the metering section are covered with the windshield member so that the metering section is not affected by the outside wind.

In order to solve the problem of failure measurement in which scrapers are weighed while scraping, a scraper which rotates slightly advances a little further than a predetermined division angle, Provided is a technique for controlling a precise weighing without touching a screened article.

In order to ensure the accuracy of sorting, the present invention forms a section covered with a roof so that the rollover can not be metered between the scrapers and the scrapers, and the weighing plate (load cell) (Not shown) in the local panel 401 when two rollovers between the scrapers and the scrapers are mistakenly turned on. When this button is pressed, only the circular rotating plate After pausing and removing one of the two injections to create a normal injection condition, the button is released to provide a configuration in which normal operation is resumed.

2. Configure a sensor to eliminate discharge error of rollover.

3. Circular bottom plate and round plate provide peak (PEEK = Polyether ether ketone) plate of t15 degree to maintain perfect flatness,

The present invention provides an assembly technique that further comprises a circular stiffener plate, a peak plate of about t15, so that the circular bottom plate and the circular spindle can maintain exact concentricity and balance.

The circular bottom plate and the metering plate are provided with scraping depressions to prevent any selected items from being moved between the scraper and the circular bottom plate.

4. The upper surface of the carrier, including the round bottom plate and the metering plate, provides another embodiment of forming curved surfaces corresponding to the abalone shells.

5. The load cell is provided with a gap adjusting bolt to protect the load cell from being damaged even when an excessive load is applied.

6. Provide a cylinder room that is closed at the bottom of the frame but can be opened at the bottom.

7. Provides a technique that can easily attach a los cell only at the time of screening, and easily detach and store the los cell when the operation is finished.

The present invention may, however, be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of a sorting apparatus according to an embodiment of the present invention. FIG. 2 is a side view of a sorting apparatus according to an embodiment of the present invention, and FIG. 3 is a plan view of a sorting apparatus according to an embodiment of the present invention.

1 to 3, an embodiment of the present invention includes a frame 10, a conveying unit 100, a metering unit 200, a discharge conveyor 300, a sorting control unit 400, And a servo system (not shown).

The sorting control unit 400 controls the discharging device 40 corresponding to the weight of the sorted goods measured by the measuring unit 200 so that the sorted goods are sorted and discharged according to the weight.

The frame 10 serves as a skeleton of the weighing apparatus according to the present invention and can be made of a plate-shaped metal material and includes a left frame 10-1 and a right frame 10-2, .

A plurality of longitudinal members 11 are provided inside the frame 10 and are integrally fixedly coupled to the frame 10 to enhance the durability of the frame 10. A reducer base plate (13) is provided at one side inside the frame (10). A decelerator 16 integrally coupled to an index motor 15 is fixedly coupled to an upper portion of the decelerator base plate 13.

A chain sprocket (not shown) is disposed on the head pulley 60 and the tail pulley 61, respectively, so that the belt 63 is supported by the head pulley 60 and the tail pulley 61, The belt 63 can be the discharge conveyor 300 operated by the motor 62. [ Since the conveyor is a known technology, a detailed description thereof will be omitted.

At the lower side of the frame 10, there are at least two legs 70. On the underside of the legs 70, a wheel 71 for facilitating the movement and an adjustable seat (not shown) for firmly fixing the overturning and sorting device on the floor can be attached.

The left side frame 10-1 and the right side frame 10-2 can be easily cleaned so as to clean the crushed pieces of the abalone shell falling down from the belt 63 of the discharge conveyor 300 and the debris 600 such as seaweed, A plurality of cleaning tools 700 may be provided on the side surface.

The carrying unit 100 in the present invention comprises a circular bottom plate 22, a circular rotary plate 20 and a plurality of transfer scrapers 21.

The circular bottom plate 22 is a circular plate, and is located in a locus where a plurality of transfer scrapers 21 are divided and rotated. When the sorting article is inserted between the scraper 21 and the scraper 21 of the circular bottom plate 22, the sorting article placed on the circular bottom plate 22 is moved to the measuring plate by the divided rotation of the transfer scraper 21. Some of the circular bottom plates 22 are cut off and are in an empty space. The empty space corresponds to a part of a trajectory in which the transporting scraper is divided and rotated, and a metering unit 200 for measuring the weight of the sorting article is located in the empty space.

A plurality of scrapers (21) are mounted on the circular rotary plate (20), and an intermittently rotating rotational motion is repeatedly carried out, which has a time to advance and a time to stop. The plurality of scrapers 21 are integrally fixedly coupled to the rotary plate 20 by a plurality of scraper attachment holes 20-1 provided outside the circular rotary plate 20. [

In the present invention, the shaft or long shaft and the rotating column of the cited invention are omitted. The rotary plate attaching member 16-1 is fixedly coupled to the speed reducer 16 at an upper portion of the speed reducer 16. [ The rotary plate 20 to which the plurality of scrapers 21 are attached is directly mounted on the upper surface of the rotary plate attachment member 16-1 and rotated synchronously.

A jog setting hole 16-3 is provided on one side of the upper side of the rotary plate attachment member 16-1 to rotate the jog plate 16-4 in a fixed manner and the jog plate 16-4 And the proximity sensor 16-5 is fixed at a position close to the locus of the jog plate 16-4 to provide a reference point for holding the origin of the circular plate 20.

The rotary plate 20 and the rotary plate attachment member 16-1 each have a plurality of mounting holes 16-2 and are fixedly coupled to each other as a bolt (not shown) or the like.

Therefore, when the index motor 15 is driven, the speed reducer 16 and the rotary plate attachment member 16-1 fixedly coupled to the index motor 15 are interlocked and the circular rotary plate 20 and the plurality of scrapers 21 are synchronized So that they rotate integrally at the same time.

Here, the material of the circular rotary plate 20 can be variously tried, but peaks (PEEK = polyether ether ketone) can be used in the embodiment of the present invention. The peak is a relatively thick thick plate having a thickness of about 15 mm. However, when the sorter of the present invention has a purpose of increasing the processing speed, A thin plate of about t6 to t8 may be used to reduce the inertia generated by the split rotation.

In addition, the peak is a material that is strong against salinity and has a light specific gravity and can lower the load rate during rotation, and is advantageous in that it is not deformed by heat even when it is exposed to the sun for a long time outdoors. However, the material of the rotary plate 20 in the present invention is not limited to the above-mentioned peak.

It is a principle that the circular bottom plate 22 is a peak plate having a flatness of about t15 mm.

The circular bottom plate 22 is designed such that the upper surface of the circular bottom plate 22 keeps the flat surface and the scraper 21 is moved to the measuring plate 53 and placed on the flat surface As a rule.

However, as described in the present invention, it is preferable that the embodiment is different when the selected article is rolled over.

That is, as shown in FIGS. 13 to 18, the upper surface of the circular bottom plate 22 and the trajectory of the measuring plate 53 to which the rollover is to be contacted should form a fan curved surface with a downward center rather than a flat plane.

If the upper surface of the circular bottom plate 22 and the measuring plate 53 are flat, the shell of the abalone to be moved on the upper surface is a curved surface, and an abalone thrown in a short time of about 0.4 second by a scraper It will cause the defect of measurement on the upper surface of the measuring plate, and the measurement error may be several tens of g, so that the role of the fine sorting device can not be expected.

Conversely, if the upper surface of the circular bottom plate 22 and the upper surface of the metering plate 53 are curved surfaces, the shell of the overturning stably moves the circular bottom plate 22, Thereby improving the measurement accuracy of the sorter of the present invention.

In order to achieve this object, in one embodiment of the present invention,

And a plurality of fixing brackets 33 are provided on the upper surface of the circular bottom plate 22 at regular intervals along the circumference.

A rail guide plate 34 is attached to the fixing bracket 33. The rail guide plate 34 is provided with a plurality of rail setting portions 36. [

A plurality of sectional rails 35 are fitted to the plurality of rail setting portions 36. The upper surface of the sectional rail 35 has a curved cross section and a curved cross section having a fan structure with a downward center Respectively.

And the lower portion of the scraper 21 is formed as a curved section corresponding to the curved end surface of the upper surface of the rail 35. [

The lower portion of the scraper 21 may be a simple curved section but in the present invention a curved section having a plurality of protrusions 210 protruded to a position lower than the upper surface of the rail 35 between the rail 35 and the rail 35 This configuration may be a preferable configuration in which no foreign matter or a small overturning shell is caught between the lower surface of the scraper 21 and the upper surface of the rail 35.

In addition, the silicon plate 211 may be attached to one side of the scraper 21 or both sides of the scraper 21 to reduce impact noise without being damaged due to impact. It goes without saying that the material of the silicon plate 211 can be changed to another material capable of absorbing the impact.

Meanwhile, the gap between the rails 35 is kept up to about 4 mm so that no mechanical trouble is caused by the rolled up portion between the rails 35 to the input portion 37 where the rollover is to be inserted. And the foreign matter such as the residue of the abalone shell or the seaweed is easily separated by about 10 mm so as to easily fall down to the lower portion of the rail 35. [

To this end, all the odd numbers and even numbers are arranged in the order of 1, 2, 3, 4, 5 to the input unit 37, and the rails 35 of the drop unit 38 are arranged in the order of 1, It is possible to arrange only odd numbers.

However, unlike the above description, it is needless to say that the number of the odd number and even number of the rail 35 can be arranged over the entire length of the rail 35 according to the type and condition of the sorting item, and the outermost rail 35 is about 10 mm And this arrangement can be a preferable structure for preventing the rollover from being carried over the outermost rail.

On the other hand, the metering plate 53 is constituted by directly mounting the rail guide plates 34 at three positions on the center, the left and right ends, and the rails 35 .

A plurality of drop holes 39 may be provided on one side of the metering plate 53. This is because the pieces of the crumbs, debris, foreign matter, etc. in the overturned rails 35 on the upper portion of the metering plate 53, It is preferable that it is easy to drop without being laid on the metering plate 53. As shown in Fig.

In the present invention, the rail 35 is disassembled and assembled in association with the fixing bracket 33 and the rail guide plate 34, but the present invention is not limited thereto.

The rail 35, the fixing bracket 33, and the rail guide plate 34 may be integrally formed with the plastic injection molding or the like and may be fixedly coupled to each other to form the transportation unit 100, .

The organic coupling relationship of the carrier 100 will be described with reference to the frame 10 as follows.

The rollover sorting apparatus according to the present invention includes a reducer base plate 13 for fixing the lower surface of the speed reducer 16 to a fixed position while being positioned at one side of the inside of the frame 10.

A decelerator base plate mounting hole 13-1 is provided on one side of the frame 10 and a decelerator base plate 13 provided inside the frame 10 is connected to the bolt hole 13-1 through a reducer base plate mounting hole 13-1. Or the like.

A reducer coupling hole 16-6 is provided on the reducer base plate 13 to fix a speed reducer 16 coupled to the index motor 15. A rotary plate attachment member 16-1 A circular rotary plate 20 is fixedly coupled to the upper side of the rotary plate attachment member 16-1 and a plurality of scrapers 21 are provided on the outer periphery of the circular rotary plate 20 in a divided manner.

When the index motor 15 is driven, the rotary plate attaching member 16-1, the circular rotary plate 20, and the scrapers 21 rotate simultaneously.

In the present invention, the motor for driving the circular rotary plate 20 and the like is specified by the index motor 15, but the present invention is not limited thereto. That is, the drive motor can be a general servomotor, and any other device capable of achieving the split rotation pursued by the present invention is included in the scope of the invention.

On one side of the frame 10, the circular reinforcing plate 101 and the circular bottom plate 22, there is provided a bottom plate mounting hole 22-5. By the bottom plate mounting holes 22-5 A circular reinforcing plate 101 is fixed to the upper side of the frame 10 and a circular bottom plate 22 is fixedly coupled to the upper side of the circular reinforcing plate 101. The circular reinforcing plate 101 and the circular bottom plate 22 are provided with a reducer 16 can be passed therethrough and is provided with a reducer passage hole 22-1 which can be accommodated.

In the present invention, a circular reinforcing plate 101 is provided between the frame 10 and the circular bottom plate 22 in order to strengthen the structure, but the present invention is not limited thereto. That is, the circular bottom plate 22 can be directly attached to the upper side of the frame 10 with the circular reinforcing plate 101 omitted, and such a configuration in which the circular reinforcing plate 101 is omitted is formed by the circular bottom plate 22 So that the sorted goods can be set to a minimum drop height when they are inserted into the upper surface of the belt 63. This makes it possible to provide a sorting article for stable landing.

Both the circular reinforcing plate 101 and the circular bottom plate 22 are characterized in that they are applied with a relatively thick plate having a thickness of about 15 mm and a very high flatness is maintained.

In order for the circular bottom plate 22 and the circular rotary plate 20 to be horizontal, that is, to have the same clearance gap, the present invention provides the following assembly technique.

The upper circular reinforcing plate 101 and the circular bottom plate 22 are fixed to the frame 10 and a plurality of spacing members (not shown) are arranged at equal intervals along the circumferential surface of the circular bottom plate 22 And the circular rotary plate 20 is placed on the space holding members.

At this time, the circular rotary plate 20, the circular reinforcing plate 101, and the circular bottom plate 22 are provided with a plurality of concentric holes 102 at the same angle and distance from the center so as to be concentric, And the circular bottom plate 22 and the circular rotary plate 20 are tightened until the spacing members are brought into close contact with each other.

When the rotary plate attachment member 16-1, the reducer 16, and the reducer base plate 13 are integrally fixed and connected to the lower side of the circular rotary plate 20 in a state where the concentricity is formed and the parallel state is maintained The frame 10 and the reducer base plate 13 are firmly fixed through the reducer base plate mounting hole 13-1 provided at one side of the frame 10. [

Then, when the bolts which fixed these pieces (20, 101, 22) are removed and a plurality of spacing members are removed, the lower surface of the scrapers (21) and the upper surface of the circular bottom plate (22) .

As described above, the driving structure for the divided rotation of the circular rotary plate 20 provides a simple but mechanically stable structure. As a result, the overturning screening device can perform stable weighing work and precise screening work is possible.

In the above, the outer side wall mounting hole 20-5 is formed on the outer side surface of the circular rotary plate 20 and the circular bottom plate 22, and the outer wall 23 can be fixedly connected as a bolt.

The debris such as the abalone shell does not rest on the metering plate 53 but falls easily on the closed curve 24 of the circular bottom plate 22 on the entrance side of the closed curve 24 as viewed from the locus of the progress of the scraper 24 And has an entrance plate 22-8 having an oblique sloped surface so that the overturning protuberance is not caught on the shoulder of the closed curve 24 of the circular bottom plate 22. [ An outer guide 22-9 can be formed between the outer wall 23 and the upward bending 53-2 formed at the outer periphery of the measuring plate 53 to prevent the overturning of the abutment due to centrifugal force.

In addition, the circular bottom plate 22 may be provided with a plurality of debris drop holes 22-10. The debris drop holes 22-10 are formed on the inner side of the locus when viewed from the locus of the scrapers 24 And the residue remaining on the circular bottom plate 22 is not piled up on the upper surface of the circular bottom plate 22 but will help to fall to the lower side of the circular bottom plate 22. [

However, the constituent items such as the dregs dropping section 22-7 and the slope falling slope 22-8 and the dregs dropping hole 22-10 described in the present invention are not limited to the kind, Of course, can be omitted.

The metering unit 200 of the present invention will be described in detail as follows.

A key component in which the sorter of the present invention can maintain accuracy even during rolling, pitching, and irregular and sudden shocks on the ship is to provide a technique using a plurality of electronic scales.

The rollover is placed on the circular bottom plate 22 and then a single closed curve 24 is encountered during intermittent split rotation stopping while moving and a plurality of meters 50, 51, 52 provided inside the closed curve 24, The weight is measured and then the closed curve 24 is escaped and returned to the circular bottom plate 22 and then moved to the drop conveyor 300.

The metering unit 200 of the present invention includes metering at least twice for one overturn, but in the embodiment of the present invention, metering is performed three times. Each of the first, second and third meters 50, 51 and 52 may be constituted by a first meter 50, a second meter 51 and a third meter 52, 53, a load cell 54, and a load cell base 55.

The load cell 54 is provided with a metering plate stiffener 53-1 on the upper side by a load cell fastening hole 54-1 provided on one side of the metering plate 53, Respectively.

The material of the metering plate 53 may be variously used. In the present invention, PC (Poly Carbonate) is applied,

The downward bending 53-3 protruding upward is formed on the outer surface so that the rolled overturned scraped by the centrifugal force can not escape from the metering plate 53 and the downward bending 53-3 protruding downward except for the outer surface .

This structure makes it impossible to directly contact the load cell 54 when cleaning the water, and the accuracy of the load cell 54 is degraded when moisture or moisture is encountered as an electrical resistor. Therefore, in order to protect the load cell 54 It becomes a preferable structure.

It is preferable that the load cell fastening hole 54-1 provided on the upper surface of the weighing plate 53 is subjected to dish head machining while the overturn proceeds along the locus of the scraper 21 and the dish head bolt is applied .

The metering plate stiffener 53-1 serves to prevent contact between the load cell fixing portion 54-2 and the metering plate 53 and serves as a reinforcing member for enhancing the durability of the PC plate.

The load cell fixing portion 54-2 can be coupled with the load cell base 55 and can constitute a load cell base color 55-1. In this case, one side is provided with a load cell base color fixing hole 55-2 to fixedly connect the load cell base collar 55-1 and the load cell base 55, and then fix the load cell fixing portion 54-2 to the other side Can be combined.

The load cell base 55 and the circular bottom plate 22 are provided with a load cell base fastening hole 58 so that these members 55 and 22 are integrally assembled by means of bolts or the like.

The first, second and third meters 50, 51 and 52 integrally connected to the load cell base 55 have load cells 54 respectively. Since the load cells 54 have a bad influence on moisture and water, In the invention, the load cell 54 is not directly wired into the screening control unit 400, but the water cell connector 54-5 between the load cell 54 and the screening control unit 400 is provided with a waterproof connector 54-6 (Connecor) And a connection jack 410 (Jack) is provided on one side of the outer wall of the screening controller 400.

In this case, the sorting apparatus of the present invention is designed such that the load cell 54 is assembled together with the load cell base 55 after the sorting operation is completed to prevent the load cell 54 from being corroded and broken from the sea breeze and moisture containing the salt. The waterproof connector 54-6 and the connection jack 410 are detached from the circular bottom plate 22 while the load cell cable 54-5 is detached from the circular bottom plate 22. Therefore,

The load cell 54, the load cell base 55, the load cell cable 54-5 and the waterproof connector 54-6 are separately stored in a dry place, Provides a method of use.

However, it is needless to say that the components of the load cell cable 54-5 and the waterproof connector 54-6 are not necessarily constructed, and may be omitted if necessary.

On one side of the load cell base 55 is provided a protrusion 55-3 as many as the number of the load cells 54 to be used and a protrusion 53-3 located in the vertical lower portion of the load cell fastener hole 54-1. One end of the load cell 54 is provided with a tap hole 55-4 through which the excessive load preventing adjustment bolt 55-5 is adjusted up and down so that the load cell 54 is moved in the " Lt; / RTI >

The excessive load prevention control bolt 55-5 maintains a state of being close to the load cell 54. The load cell 54 can be freely pushed until a load of, for example, 1000 g is applied. However, if the load exceeds 1000 g, So that the load cell 54 can be prevented from being damaged even when an unexpected excessive load is applied due to contact with the bolt 55-5.

The load cell 54 is generally damaged by a load of 1.5 times or more of the standard capacity or pressure. As a result, if an external force of about 5 kg is applied, there is a danger that the load cell is damaged and replaced.

On the other hand, since the overturned circulation has a maximum weight of about 4 / kg, which is only about 170 g / minute, there is no overturn that is more than 300g at most. When a load of 1000g or more acts on the load cell 54, Since the load cell 54 can no longer be bent due to the excessive load prevention control bolt 55-5, the load cell 54 can be protected without being damaged even when an excessive load is applied, The load cell 54 can perform a normal weighing operation without touching the excessive load prevention control bolt 55-5 yet.

This configuration prevents the load cell 54, which is an important component of the overturning device according to the present invention, from being partially damaged, or prevents serious damage to the extent that replacement is required, thereby ensuring the accuracy of the sorting operation.

The first meter 50, the second meter 51 and the third meter 52 may be disposed in the closed curve 24 of the circular bottom plate 22 in this order.

The rollover placed on the upper surface of the circular bottom plate 22 is moved by the scraper 21 and then intermittently rotates in the intermittent split rotation to enter the single closed curve 24 to be placed on the first meter 50, When the third measurement is performed in the third meter 52, three measurement information on a specific one overturned weight is displayed as an indicator (indicator) (Not shown), and the weight of the overturned deformed into the electronic weight value at the indicator is transferred directly to the PLC (Programmable Logic Controller), that is, the CPU (Central Processing Unit) The solenoid valve (not shown) starts to operate so that the discharge device 40 corresponding to the solenoid valve is operated.

At this time, there are various algorithms for determining the final weight value by using the weight value measured by three meters for one rollover. In the embodiment of the present invention, if all three of the three weight values are the same, the same weight value is selected as the actual weight. If two of the three weight values are the same and one weight value is different, And if the three weight values are all different values, the median value is selected as the actual weight value.

In this configuration, even if there is a moment when an external impact condition is applied to the load cell 54, the error is ignored without being reflected in the final weight value. Therefore, it is crucial for the accurate selection pursued by the present invention .

However, the metering plates 53 of the first meter 50, the second meter 51, and the third meter 52 may be subject to a slight change in weight.

For example, at the beginning of the operation, the water on the abalone may fall off as time passes on the weighing plate 53 that has been dried, and the weight of 3g to 4g may be measured more heavily than the actual abalone weight. Impurities such as pieces or residue of kelp can be measured while being placed on the upper surface of the measuring plate 53.

In order to solve the error of measurement failure and ensure the accuracy of selection, the present invention forms a section covered with a roof so that the rollover can not be put between the scrapers 21 and the scrapers 21 to be metered, It provides a configuration that automatically resets (zeroes) when passing through this weighing plate.

At the same time, when the problem of the insertion failure can not be solved when two pieces of rollover are mistakenly inserted between the scrapers 21 and the scrapers 21, the load cell 54 is recognized by the large rollover of two pieces, Can be a serious cause of poor screening of the two little abalone that had been misplaced. However, it can be difficult and dangerous to correct errors between scrapers (21) that are performing fast split rotations in 0.4 to 0.5 second cycles, realizing that the person in charge has made a mistake later.

In order to solve the error of input failure and to ensure the accuracy of the selection result, the present invention includes an emergency stop switch (not shown) on the local panel 401 so that when the button is pressed, only the circular rotary plate 20 is temporarily stopped, After one of the two is removed to create a normal input condition, the button is released to provide a configuration in which normal operation is resumed. That is, although the circular rotary plate 20 is temporarily stopped, the components of the present invention including the discharge conveyor 300 are normally operated.

If all of the components of the present invention including the discharge conveyor 300 are simultaneously stopped after the emergency stop switch is pushed and then simultaneously operated again, the overturned normally before the input failure is discharged in the direction "E" ≪ / RTI >

The configuration in which the automatic zero point is reset as described above and the configuration of the emergency switch for preventing the error of the input will be a preferable configuration for the present invention to perform accurate selection.

As the above-described emergency switch, a normal ON / OFF switch or a toggle switch can be used.

On the other hand, even if the weighing unit 200 correctly measures the actual weight of the abalone, there may be other obstacles that cause bad measurement in the abalone screening operation. It is a reality that the metering section 200 is exposed to the wind on the ship.

Generally, the load cell 54 receives a load corresponding to the weight of the overturned object and generates warpage. The physical deformation amount (warpage) generated in the load cell 54 is transmitted to an indicator (not shown) The load cell 54 and the weighing plate 53 may have errors of several g and may be affected in real time, which is a serious problem.

In order to solve such a problem, an embodiment of the present invention provides a wind tunnel 90 (tunnel). The configuration of the tunnel 90 is as follows.

The basic outer wall 91 is attached as a bolt to the outer wall attachment tab 25 formed on the side of the outer wall forming the thickness of the circular bottom plate 22. An outer flange 92 is provided at the upper end of the basic outer wall 91. A cover 93 is fixedly coupled to the outer flange 92 to prevent the wind from being applied to the upper surface of the metering plate 53 including the load cell 54. The inside surface and the side surface of the cover 93 are in close contact with the circular rotary plate 20 or the scraper 21 which is rotated with the silicon plate 94 mounted thereon to prevent the outside wind from entering the inside of the wind tunnel 90 And is provided while maintaining a minimum clearance so as to prevent interference or collision with the circular rotary plate 20 or the scraper 21.

A bottom wall 95 and an inner wall 96 are provided at the lower end of the basic outer wall 91. A damper 97 (see FIG. 1) is provided to accommodate debris, debris, damper plate.

In this configuration, the base outer wall 91, the cover 93, the silicon plate 94, the inner wall 96, and the damper 97 plates surround the measuring plate 53 including the load cell 54 in all directions The shape of the tunnel 90 for blocking the wind is formed.

With this configuration, the weight sorting apparatus according to the embodiment of the present invention can perform the measurement operation with little influence of the wind even when the wind is blown from either the up, down, or all directions.

If the damper 97 is omitted, it is possible to more easily fall off the debris or residue of the overturning, and the cable of the load cell 54 can be sorted There is an advantage that it can be directly connected to the control unit 400.

In the embodiment of the present invention, the circular rotary plate 20 stably rotates in a split manner, another configuration is provided which helps to accurately measure the sorting apparatus. That is, the plurality of scrapers 21 are rotated while being attached to the circular rotary plate 20, and the rotating scrapers are rotated by a small distance that is slightly advanced, So that it is possible to provide a method of accurately controlling the weighing without touching the scrapers (21) or the scrapers (21) or early fishes.

For example, if the width of one cycle of the scraper 21 is 100 mm, the control unit controls the scraper 21 to move forward by 110 mm, then move backward by 10 mm, ) Moves the overturned and then makes a proper backward movement so as not to be metered while adhering to the overturn, and then moves 110mm again when the weighing operation is completed. This split rotation method allows precise weighing without the overturning and scraper 21 being touched.

However, in the embodiment of the present invention, it is not always necessary to slightly reverse after advancing in the split rotation, and it may or may not be applied depending on the type, size, and state of the sorting article.

In another embodiment of the present invention, a plurality of scraping depressions 22-2 may be provided on the upper surface of the round bottom plate 22. [ The scraper 21 is likely to be scraped while being caught in a gap between the circular bottom plate 22 and the scraper 21 in the case of a small rolled sheet, In the case of the same fish, the fins or tails can be spread wrapped in the gap.

The overturning or protrusion moved while being caught in the gap can reach the metering section 200 while being caught in the gap. In the case of overturning in a clearance, pressure is applied to the electronic balance of the metering section, thereby making a failure measurement in which an error of several tens of grams occurs.

A plurality of scraping depressions 22-2 provided in the present invention can solve this problem. That is, the scraping depression 22-2 has a width of about 10 mm and is a kind of track formed in a circular shape starting from the center of the circular bottom plate 22 with a depth of about 5 mm. The scraping depression 22 The bottom surface of the scraper 21 has a protruding portion and the lower surface of the protruding portion is formed to be equal to or slightly lower than the upper surface of the circular bottom plate 22, So that the scrapers 21 can be scraped without being caught by the scrapers 21,

Such a structure is a preferable structure for solving the cause of measurement failure due to scrapping failure.

As shown in FIG. 4 and the like, the overturn that has fallen onto the upper surface of the belt 63 of the discharge conveyor 300 after passing through the metering unit 200 has the scraper 21 at right angles to the advancing direction of the belt 63, The guide 59 is provided in the embodiment of the present invention in order to prevent disengagement when it is about to be deviated toward the outer surface of the belt 63 by inertia. The guide 59 is arranged in parallel with the advancing direction of the belt 63 so as to be paired with the left and right sides of the belt 63. In another embodiment, A PC material having a structure preferable to be guided to move to the center of the belt 63 and being strong against elasticity and impact and having excellent restoring force can be used.

The overturned thrown by the scraper 21 at right angles to the traveling direction of the belt 63 may be inverted in the process of landing on the upper surface of the belt 63, The overturned scraper 21 pushes the overturn in a state in which it can not quickly get out in the advancing direction of the belt 63. When the overturned scraper 21 And the guide 59 may occur.

In order to prevent the scraper 21 from being damaged or causing fatal damage to the entire driving part, the present invention is characterized in that the circular bottom plate 22 is provided with a frame cutting section And the guide 59 is provided as a PC plate so that the guide 59 is a safety wall formed of a PC plate of a thin plate, The guide 59 can be slightly lifted and dropped through the frame cutout portion 22-0. Even if the guide 59 is not easily released in the traveling direction of the guide 59, It will be restored.

However, if the circular reinforcing plate 101 is omitted in the present invention, the gap between the locus generated by the lower end of the scraper 21 and the upper surface of the belt 63 will have a minimum clearance of only about 2 to 3 mm, The guide 59 may be omitted.

However, in any case, the irregular overturn is thrown in a direction perpendicular to the belt 63. In addition, since the belt 63 maintains a relatively high speed of about 700 mm / sec, And there is an individual difference in time for traveling at the same speed as the surface of the belt 63. The time difference due to the unstable landing results in a scrapping failure, E ", which is the end of the discharge conveyor 300, without being scraped by the discharge scraper 30 corresponding to the predetermined weight.

  Accordingly, the embodiment of the present invention provides the sensor 80 to solve such a problem.

Since the setting of the time for scraping by the discharge scraper 30 is counted from the time the sensor 80 is passed through the sensor 80, the rollover of which the measurement is completed due to the sensor 80 is counted, Scraped at the correct time in the correct discharge direction, and can be dropped.

However, the guides 59 may be installed on only one side of the sensor 80, depending on the type and size of the sorting article, and may be installed either on the front side or on the rear side of the sensor 80 or both.

The following describes the discharge conveyor 300 in more detail. A discharge conveyor 300 is provided on one side of the pair of frames 10. On the upper side of the frame 10, a plurality of discharge scrapers 30 are provided for discharging falling abdomen after falling on the upper surface of the conveyor belt 63 of the discharge conveyor 300.

A cylinder chamber 500, which is a closed space for accommodating the discharging device 40, is provided below the frame 10. A plurality of longitudinal members 11 are provided at one side of the inside of the cylinder chamber 500. An air cylinder 42 is provided for operating the discharge scraper 30 on the basis of the longitudinal member 11. A scraping shaft 43 is formed at the end of the air cylinder 42 so that the scraping shaft 43 and the discharge scraper 30 are operated simultaneously when the air cylinder 42 is operated. When the overturned weighing pan is placed on the upper surface of the discharge conveyor 300 and then moved, a corresponding solenoid valve (not shown) is operated and the corresponding air cylinder 42 ). The linear reciprocating motion by the operation of the air cylinder 42 causes the rotating motion of the scraping shaft 43 and the discharging scraper 30 fixed to the lower end of the one side of the scraping shaft 43 is moved on the belt, A scrapping and discharging device 40 is constructed.

The belt 63 of the discharge conveyor 300 may be variously applied to a rubber belt, a urethane belt, etc. However, in the embodiment of the present invention, a plastic material having a high porosity and having good air permeability and easy cleaning of foreign matter The belt 63 is used.

The cylinder chamber 500, which is a closed space for accommodating the discharge device 40 at the lower part of the frame 10, is closed at one side by the inner frame 10-1 and the other side by the outer frame 10-2. And the upper surface is blocked by the cylinder room ceiling 10-3, but the lower portion is structured so that it can be opened and closed for inspection of the apparatus.

That is, the bottom material 10-4 is provided to open the device for inspection, and may have a closed structure at normal times. To this end,

The cylinder chamber 500 is provided with the hinge 10-5 on one side and the clamp 10-6 on the other side and the packing material 10-7 between the frame 10 and the bottom material 10-4. Is not exposed to moisture.

The selection control unit 400 or the servo system including the control program may be disposed on the lower side of the frame 10. [ A local panel 401 having only a touch panel (touch screen), an ON / OFF switch, and an emergency switch may be separately provided on the upper side of the frame 10 to facilitate the operator's convenience.

Here, the operation of the screening controller 400 will be described in more detail as an example.

The rollover inserted between the scraper 21 rotating in the split direction moves along the upper surface of the circular bottom plate 22 and immediately after the scraper 21 is placed on the upper side of the measuring plate 53, There is a moment when we stop the exercise. At that moment, the load cell 90 provided at the lower side of the metering plate 56 receives a load corresponding to the weight of the rolled over which is placed, and warping is generated. The physical deformation amount (warpage) generated in the load cell 90 is transmitted to an indicator (not shown) in real time, and the weight of the overturned deformed into the electronic weight value at the indicator is directly detected by a programmable logic controller (Central Processing Unit), and a solenoid valve (not shown) starts operating under the control of the PLC so that the discharging device 40 corresponding to the electronic weight value is operated. The operation of the solenoid valve causes the air cylinder 42, the scraping shaft 43 and the discharge scraper 30 to interlock with each other at the same time, thereby dropping the sorting article into a predetermined discharging place and storing it in a receiving container (not shown) . These operations and settings can be displayed and manipulated on the touch screen of the local panel 401.

This dual system will be a useful configuration that can be applied in situations where quick work is required for freshness.

 In the present invention, the total number of the discharge scrapers 30 is six, three for the left and the right, but the present invention is not limited thereto.

Since the overturning is generally classified into sixteen kinds of grades by weight, the overturning screening apparatus according to the present invention can constitute a total of sixteen discharge scrapers 30 of eight on each side, and it is natural that the overturning scraper 30 can be more than necessary.

In addition, even if the metering plate 53 and the load cell base 55 for constituting the load cell 54 are configured somewhat differently from the method described and shown in the present invention, a minor modification yielding a similar result from the present invention All fall within the scope of the present invention.
