Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic pre-

Electronic weighing machine, sensor conveyor, vibration feeder, vibration conveyor,

Patent registration 10-1521755 Circular injection device capable of compression arrangement

Registered Utility Model Registration No. 20-0474829 Weighing belt conveyor with conveying surface space

There are two problems to be solved in the sensor conveyors with all existing electronic checkweighers, ie, aquatic conveyor for aquatic products or conveying surface space

First, it was necessary to develop an automatic input device capable of performing input, sorting, and product classification tasks.

Secondly, it was necessary to have an efficient sorter capable of large-capacity processing in a short time.

Currently, early-stage processing plants produce an average of 500 to 1,000 days per day.

The average value of this figure is about 15,000, which is about 15,000. In order to handle the selection process by conventional methods, three people take three hours and nine balls are needed. One of them is selected by feeling or by scales. Performs a hard work of throwing to the classification site.

Some machining factories mechanize the sorting process to perform weight sorting. In this case, two people need 3 hours and 6 balls are needed.

Since the checkweigher is semiautomatic, one person should be supplied continuously one by one to the sorter every 3 hours, and the other one should be sorted by 6 ~ 9 different weights In order to carry out the work or to receive the selected products, an empty box must be supplied and replaced at each selector outlet.

The reason why it takes 3 hours is because the processing speed of the semi-automatic sorting machine is only 80 micro / min. Therefore, it has been necessary to develop a sorting machine capable of handling a large capacity, and at the same time, it was necessary to develop an automatic feeding device will be.

The present invention has been made in order to solve such problems,

The present invention provides a technique capable of processing an early 15,000 beats per person per hour to complete a task as one beast.

That is, the present invention provides a wide-width sensor conveyor capable of 3.57 times as much processing capacity as a conventional sorter,

The wide-width sensor conveyor senses the weight and develops a command system of an indicator that transmits the result of the detected weight to the PLC, thereby increasing the accuracy of the measurement,

And at the same time providing the automatic feeder capable of intermittently feeding the early automatic feeder intermittently at a time while only one person is moving the selected feeder and re-feeding the empty box to the selector outlet, .

When the present invention is applied to an early processing plant,

It is possible to make the early screening time which required 9 balls or 6 balls in one ball,

By shortening the preliminary screening time by 3.57 times, the freshness of the product is improved and it is anticipated that a breakthrough effect of securing the quality competitiveness is expected.

Hereinafter, the present invention will be described in detail with reference to the drawings. However, these drawings are for illustrative purposes only and the present invention is not limited thereto, and all minor technical variations that can achieve the object of the present invention fall within the scope of the present invention.

The present invention relates to a vibration quantity supply device (100) for realizing automatic insertion of an automatic supply device,

A combination of a wide sensor conveyor 60 and a sensor pre-conveyor 50 set to realize a large capacity process.

A vibrating quantity supply apparatus 100 according to an embodiment of the present invention includes a case 10 having a vibration means, a supply unit 11, a discharge unit 12, at least one two- And a plastic bellows nozzle 14 for easily adjusting the position of the two-layered formation restraining bar 13 by one touch,

A support frame 30 provided with a wheel 20 is mounted on the bottom of the case 10 and a buffer member 30 for buffering vibrations is provided between the support frame 30 and the case 10 40 are provided,

And a pair of vibration motors (M) for applying vibration to the case (10)

And the case 10 is inclined at an end of the discharge part 12, which is the opposite direction of the supply part 11.

The case 10 made of a plate-shaped metallic material is caused to vibrate by a pair of vibration motors M for causing vibrations to be arranged left and right under the case 10, The prematurely charged hopper space portion 11 is moved forward to the discharge port 12 and an inverter 90 is provided to adjust the intensity of the vibration. Since this is a known technique, a detailed description will be omitted.

The case 10 has a flat bottom surface 10-1 at the center of the inside in the width direction and has a sloping side surface 10-2 inclined obliquely at both ends in a bent state as a plate- do.

A motor base plate 10-3 is provided below the case 10 and a pair of vibration motors M are fixedly coupled to both sides of the motor base plate 10-3.

Two cushioning member supports 41 are fixedly coupled to the lower side of the case 10, and the cushioning member supports 41 are fixed to both ends of the case 10 by means of welding or the like. So that the plastic bellows nozzle 14 is coupled to each of the four sockets 42 and the other ends of the plastic bellows nozzle 14 are provided on one side of the two- And is fixedly coupled to another socket 42,

In such a configuration, while the case 10 continuously vibrates and moves the inserted early stage from the direction of the supply part 11 to the direction of the discharge part 12, the two- So that the two layers can not be formed, and all the premises are formed at a predetermined interval while forming a single layer, and are spaced from the flat bottom surface 10-1 so as to be sequentially discharged one by one through the discharge port 12 And to do the role.

Here, the vibration of the flat bottom surface 10-1 will be described in detail.

The case 10 including the flat bottom surface 10-1 is formed so that the entire case 10 is reciprocated at an angle of 30 DEG which is the vertical direction of the vibration motor M in which the pair of vibration motors M are set. The protrusions put on the upper side of the bottom surface 10-1 move upward by 30 占 in the direction of "a ", and then freely fall in the direction of" b "

If there is no two-layered formation restraining bar 13 above the flat bottom surface 10-1, all the precursors will move randomly toward the discharge portion 12 and maintain a constant spacing through the discharge portion 12 Uncertainty will result in irregular discharges of one, half, or two per unit hour.

However, according to the present invention, the early protruding in the direction of "a" at an angle of 30 degrees is vibrated and controls the force that continuously and excessively moves forward.

If there is no two-layer formation restraining bar 13, it is possible to see that the early stage is not advanced yet, but the early stage is at an angle of 30 ° and it tries to bounce continuously in the direction of "a" In contrast to the three-layer formation, irregular movement and discharge occur,

If there is a two-layer formation inhibiting bar 13, the preceding early stage can not proceed any longer when the preceding stage is not progressing and stagnating.

In other words, the early angle is 30 °, it tries to bounce in the direction of "a", but it collides with the rod and fails to form the second floor, The force to move forward is restrained and controlled until the located early stage starts again, and it will resume the process again only when the preceding stage is advanced. As a result, It is possible to sequentially discharge the waste water while maintaining the same structure.

Here, the case 10 including the flat bottom surface 10-1 performs reciprocating parallel movement about 3 mm to 8 mm in the "a" direction, but the two-layer formation inhibiting bar 13 is fixed in place As a result, the gap (height) between the bottom surface 10-1 and the two-layered formation restraining bar 13 is about 33 mm to 38 mm, for example, so that the fluidized-bed space portion bounces in the "a & 2 layers and 3 layers, but it is a very limited space, so that it is a preferable structure that does not suffer from difficulty in progress.

Expressed again, if the gap (height) between the bottom surface 10-1 and the two-layer formation restraining bar 13 is excessively wide, the premises will not be laid on the floor, but will be raised sideways and wrinkled, If the gap between the bottom surface 10-1 and the two-layered formation restraining bar 13 is excessively narrow, the premises do not maintain a constant gap, and only intermittent movement is carried out, It will not be able to move through the gap (gap).

Therefore, the interval (height) between the bottom surface 10-1 and the two-layered formation restraining bar 13 is frequently rapidly changed in the "X direction" depending on the size and thickness of the early stage, , "Y direction ", and" Z direction ".

Therefore, in the present invention, one or more two-layered formation inhibiting bars 13 are shown and explained in two, and the plastic bellows nozzle 14 is used to quickly adjust the two-layered formation restraining bar 13 at one-touch And the like.

The direction of the supply part 11 of the two-layered formation restraining bar 13 is formed such that the inserted early part is bent upward relatively long so as to be easily guided to the lower side of the two-layered formation restraining bar 13 along the bottom face 10-1 And the direction of the discharge part 12 is preferably bent downward so that the early part is prevented from dropping onto the pre-sensor conveyor 50 while being vibrated by the vibration.

However, it is a matter of course that the bending shape of the two-layered formation restraining bar 13 may not be given if necessary, and minor deformations can be made to improve performance.

Early distribution channels are sent to small and medium processing plants through the river bank.

Early, after being caught by the method of lanyard and net, sent to the fisheries cooperative, they are roughly sorted by hand, then stored in the box 88 and rapidly frozen. After the thawing, the wrinkles are fixed and the merchantability is lowered In order to be worried about what is happening, I work on the naming work, that is, putting it in a box arranged vertically and horizontally.

In this state, frozen goods are bought and thawed by the necessary amount in the processing factory, and then they are distributed to consumers through processes such as screening work, salt incineration work, woven work by one step size, drying work and the like.

Accordingly, as shown in FIG. 4, several horses are collected so as not to be disturbed by the number of horseshoe "Q" matched to the horses 89 in the box 88 arranged in anyway, Is inserted between the rod (13) and the flat bottom surface (10-1). The flat bottom surface (10-1) constitutes a sufficient length so as to be about 100 or so in the early stage, If the speed is calculated to be 0.3 seconds per one minute, the worker will not have to wait for about 30 seconds to complete the filling and refill. And the whole process of the sorting operation can be carried out sufficiently while preparing the box to be newly inserted.

In the present invention, the oscillation quantity supply device 100 is used as the automatic supply device for realizing the automatic early insertion, but the present invention is not limited thereto.

Although the early intervals (densities) will most ideally be arranged and arranged by vibration by using the oscillation quantity supply device 100, the constant quantity supply device may be a general belt conveyor (not shown) or a chain conveyor City) may be used. In other words,

A plurality of grains are collected so as not to be disturbed by the number of grains "Q" aligned in the box 88 arranged in the upper side of the belt of the belt conveyor composed of a plastic belt, If the velocity of the belt is controlled by an inverter or the like, the gap can not be rearranged because there is no vibration in the early stage. However, the object of the present invention as a quantitative feeder to be sought can be attained without fail.

The belt conveyor (not shown) and the chain conveyor (not shown) are well known in the art and will not be described in further detail.

A sensor conveyor 60 for measuring the weight of the early discharged through the discharge unit 12 will be described.

A typical sensor conveyor 60 passes a sensor pre-conveyor 50 having the same operating conditions as those of the sensor conveyor 60 to minimize the shock at the time of landing or landing on the sensor conveyor 60, The sorting article is received in the conveyor 60 and sensed by the load cell 51 and sent to the discharge conveyor 80. The amount of physical warping detected by the load cell 51 (applied to the load cell 51) (Not shown) to an electric signal, and the corresponding solenoid valve (not shown) corresponding to the weight corresponding to the required time is operated by a command from the PLC The scrapers 70 are operated to sort the sorted goods, which are known in the art and will not be described in further detail.

A cited inventor registered by the present applicant

Patent Registration No. 10-1521755 A circular insertion device capable of compression placement,

All the conventional sensor conveyors 60 including the weight measuring belt conveyor having the utility model registration 20-0474829 transfer space section are narrow as shown in FIG. 5 and have a long length.

As shown in FIG. 5, the length of the sensor conveyor 60 is about 35 cm, which is the maximum length of the early stage, and about 5 cm is added to the length of the sensor conveyor 60 so that the length of the sensor conveyor 60 is about 40 cm It deserves to be.

In this case, the pitch between the early and early intervals is 75 cm, which is the minimum number at which at least one prematurely enters the sensor conveyor 60 immediately after completion of the weighing and completely passing through the sensor conveyor 60 .

On the contrary, the application of the wide sensor conveyor 60 according to the present invention will be described with reference to FIG.

First, explain that the length of early days is variable and variable, but the width is not.

When the early length is 22cm, the width is about 6cm, but even when the maximum length is 35cm, the early width does not change much and is only 8cm.

Therefore, the length of the sensor conveyor 60 is 8 cm, which is the initial width, and the space of about 5 cm is added to the sensor conveyor 60 so that the sensor conveyor 60 can be constructed to be about 13 cm. As a result, the wide sensor conveyor 60 is wide, And has a short length.

Thus, in the present invention, the early and early pitches for entering the sensor conveyor 60 immediately after the completion of metering and completely passing through the sensor conveyor 60 are 21 cm, It can be seen that the mass processing of 3.57 times as much as that of 75 cm is possible.

In addition, the present invention improves the accuracy of the selection and the processing speed by improving the command system of the indicator which senses the weight in the load cell 51 and transmits the result of the detected weight to the PLC (Programmable Logic Control) .

As shown in FIG. 7,

Since all the existing sensor conveyors 60 detect that the sorting article has entered through the sensor immediately before the sorting article having passed through the sensor pre-conveyor 50 enters the sensor conveyor 60, It keeps a command system that instructs to measure.

The sensor can be applied in various applications such as an optical sensor using an optical fiber. In general, however, among photo sensors, a light receiving unit 52 and a light projecting unit 53 are provided and a visible light source is passed from the light projecting unit 53 toward the light receiving unit 52 When the receiving of the visible light source is interrupted due to the entry of the screening article, it is detected that the screening article has entered, and the following description will be sequentially described.

1. Detecting that the sorting item has been entered by the sensor and informing the PLC of this fact.

2. PLC (Programmable Logic Control) instructs the load cell 51 to detect the weight after "t" seconds.

Here, "t" is expressed as an arbitrary time that is assumed to be located at the center of the sensor conveyor 60 in consideration of the speed of the sensor conveyor 60. In other words, Is determined through several experiments so as to be a time that does not pass the conveyor 60 or fail to complete a complete entry, and the determined "t" seconds may not be the optimum appropriate setting time , Providing the cause of poor measurement, which is less than the actual weight of the early stage if not the optimal setting time.

3. The load cell (51) receiving the command of the PLC detects the weight

4. If the PLC reports how many grams of indicator

5. The PLC activates the corresponding solenoid valve (not shown) according to a preset program so that the discharge scraper 70 discharges the selected item to the corresponding position.

Here, conventionally, all existing sensor conveyors 60 have two problems.

First, the time at which the load cell 51 sets the weight to "t"

The center of the sensor conveyor 60, or the most appropriate one of the sorting items, is selected so as to satisfy both the case where the early stage corresponding to the minimum size is passed and the case where the early stage corresponding to the maximum size is passed. Position and the most accurate measurement has been performed,

Second, although it is a very short time, it takes time to go through the above-mentioned command systems.

To solve this problem, the present invention provides the following technique.

When the sorting article is placed on the load cell 51, a slight amount of physical deflection occurs in the load cell 51, and there are usually two methods for converting the amount of deflection into an electrical value in the indicator.

Firstly, as described above, after the sensing "t" seconds of the sensor, the load cell 51 measures the weight unconditionally and adopts the weight as a result of the measurement in the indicator and confirms it.

Secondly, the entire process of passing the sorting article through the sensor conveyor 60 is measured continuously (for example, about 1000 times per second) for a certain period of time after detecting the sensor "t" seconds, As a result of measurement in the method of determining and adopting. However, the second method is also difficult to produce accurate measurement data.

However, the present invention provides a method of simplifying the command system.

That is, the load cell 51 detects a moment when the selected article enters the sensor conveyor 60 and the weight is detected for the first time,

Since the sorting item has been entered, it is regarded as an instruction of the PLC to start the measurement and the measurement is immediately started.

The entire process from the instant when the selected article enters the sensor conveyor 60 to the instant when the weight is first detected through the sensor conveyor 60 to the moment when the weight becomes 0 (zero), for example, about 1000 times per second And the maximum weight, which is the peak value thereof, is determined as a result of the measurement in the indicator.

The concept of this explanation is expressed in FIG.

As a result of simplifying the command system as described above,

1. The accuracy of the weight measured by the load cell 51 is further improved,

2. The load cell 51 receives the command to measure the weight after "t" seconds in the PLC after detecting the entry of the selected item by the sensor and transmitting the detection result to the PLC, There is an advantage that can be done.

To further explain the disadvantages of the conventional method in which the sensor is used,

If the sensor detects early entry, for example, the tail enters first, the tail touches the floor completely by moisture, or the head enters first, but the defrosting state is poor and the gill is bent It is probable that the weighing can be performed while leaving the sensor conveyor 60 at an early stage, as a result, the fact that the early stage has already entered but the early stage has not been detected yet,

Even when the sensor is a reflection type of the photo sensor, when the light receiving part 52 of the sensor senses the early abdomen, the early abdomen is white, so the light reflects well and responds immediately. However, In the case of the early type of black back, there is a possibility that the color will react slowly due to the sensitivity of the light due to the light absorbing effect,

In addition, since the electronic parts are exposed to moisture at the time of cleaning the water after completion of the screening operation, there is a possibility of failure, so that omission of the sensor provided in the present invention will have a very beneficial ripple effect in actual field.

In the present invention, the case 10 is shown horizontally, but it is not limited thereto.

Needless to say, the case 10 may have a horizontal or inclined surface depending on the material properties of the input and output objects, and may have a reverse slope.

In the present invention, the two-layered formation inhibiting bar 13 is shown and controlled by the plastic bellows nozzle 14, but it is also possible to control the position of the two- And it is intended that all of the technical matters of the present invention, which can perform the role of the two-layer formation inhibiting bar 13 and adjust its position, are all included in the scope of the patent.

In the present invention, although the detailed description is omitted, all of the discharge scrapers 70 and the discharge scrapers 70 to be discharged by the discharging scraper 70 to the receiving receptacle (not shown) while the measured sorted goods move through the discharging conveyor 80 The positions of the solenoid valves, the air cylinders, the air hoses, and all the electric lines connected to each other are shifted from the bottom of the discharge conveyor 80 to the top of the discharge conveyor 80, And prevent the possibility of accumulation of foreign materials such as scales and rot, and the like.

The case 10, the load cell 51, the light receiving unit 52, the sensor conveyor 60,
