Description

Arrangement transfer device for fruit sorter}

The present invention relates to a sorting transfer device for fruit sorter which is arranged in a row to select a variety of fruits, such as citrus, melon, peach, apple, etc. and has a measurable interval.

In general, the fruit sorter is transported by placing the fruit on the keyboard cup of the measuring and classification conveyor, and measuring sugar content, color, and weight when it reaches the lower part of the measuring instrument. It is configured to fall on the grading table by tilting and accumulate in turn. In front of the measuring and grading conveyor, an alignment transfer device is installed to align the fruits, which are mixed and conveyed from the pre-processing conveyor, in a row and open at a measurable interval.

Currently used sorting device for fruit sorter installs several conveying belts composed of two V-type belts in parallel, and the 1st conveying belt has different speeds of right and left belts so that the entangled fruits are arranged in a row. In addition, the remaining conveying belts are configured to have a measurable interval between the fruits when centered on the measuring and classification conveyors so as to have a faster rotational speed while maintaining the left and right constant velocity.

However, it is difficult to maintain the constant velocity in the section where constant velocity is required due to the characteristics of the belt, which is a cause of deviation of the centerline of the fruit, and also requires frequent speed adjustment for constant velocity maintenance.

In addition to the change in tension, the belt has a large step between the conveying belt and the conveying belt and the measuring and classifying conveyor due to the driving roller and the driven roller which are structurally back and forth, so that the fruit is scattered every centering to maintain the correct posture. In the process of correcting difficult and scattered postures, it is difficult to maintain a given interval due to the step speed change of the conveying belt, and in severe cases, classification is not possible due to mismeasurement due to the deviation of the center line and the collision with the measuring instrument. As a result, it is impossible to give consumers confidence in the product and cannot get the price due to the decrease in the merchandise, and as the speed of the conveying belt increases, the phenomenon worsens, so the work efficiency decreases. Many problems have been pointed out.

The purpose of the present invention is easy to maintain and maintain the correct posture even when centering on other conveying belts or measuring and sorting conveyors on the extension line, which can eliminate erroneous measurement and further improve the work efficiency by increasing the feeding speed of fruit. To provide a sorting device for sorting fruit that can be made.

The present invention is tightly connected to each other to guide the guide rods with different diameters in each section on the left and right plates that are angled by loosening and tightening the turnbuckles to achieve the purpose, inserting a soft protective tube on the outer surface and contacting the gears of each guide rod It is characterized in that the guide rod is rotated in one direction by driving the reduction gear motor connected to the gear by engaging the gear.

However, the angle adjustment of the left and right side plate is to maintain the desired angle of the left and right guide rods from the fixed side plate may be installed so that the right and left guide rods to have an appropriate angle, it may be possible to vary the angle of the guide rod for each section.

In addition, it is not limited to varying the diameter of the guide rod to increase the distance between the fruit by changing the transport speed of the fruit, and the rotational force while changing the gear ratio or the rotational speed by a separate reduction motor for each section while the diameter of the guide rod By giving different values, you can get satisfactory results.

1 is a plan view of the present invention, the present invention is to adjust the inclination angle of the long left and right side plates (4) and 6, and the left and right side plates (4) (6) which are installed to be rotatable on the support frame (2). Guide rods 12, 14 and guide rods 12 and 14, which are closely connected to the turnbuckles 8 and side plates 4 and 6 so as to face each other at appropriate intervals, and are covered with a soft protective tube 10. (16) and connecting gears (20) and (22) and connecting gear (14) is composed of a reduction motor for transmitting power to the guide rod.

The left and right side plates (4) and (6) are connected to the support frame (2) with shaft pins (26) and (28) to enable rotational operation, which is to obtain the inclination angle of the guide rods (12) and (14). Separate configuration by section to have a separate turnbuckle (8) may be to vary the angle of inclination for each section.

However, the inclination angle adjustment of the left and right side plates 4 and 6 is for the right and left guide bars 14 and 16 to have an appropriate inclination angle, and it is satisfied that the guide rod has a desired inclination angle, regardless of whether the left and right side plates are adjusted.

In addition, when adjusting the inclination angle of the guide rods 12 and 14 through the left and right side plates, the left and right side plates may be configured to have a long integral shape, and may be adjusted to have the same inclination angle between the bulbs. will be.

The turnbuckle 8 which adjusts the inclination angle of the left and right side plates 4 and 6 has a general structure, and the end of the male and female bolts is connected to the upper end of the left and right side plates 4 and 6 by axial pins to loosen and tighten the turnbuckle 8. The left and right side plates 4 and 6 are configured to rotate so that the inclination angle is adjusted.

In the above, the turnbuckle 8 is selected to facilitate the adjustment of the inclination angle, in addition to using a long bolt and several nuts or by using a fixed rod may be fixed to the right and left side plates to have a proper inclination angle. The left and right side plates do not necessarily require tilt angle adjustment.

The guide rods 12 and 14 of the left and right side plates 4 and 6 have a thickness that is thinner toward the rear of each section so that the fruits A are conveyed at a higher speed with the thickness difference of each section and are classified by sections. It is desirable to install as closely as possible with minimal spacing, and the height thereof is preferably horizontal.

However, the present invention is a means for obtaining a difference in the feed rate of the fruit per section, including the thickness of the guide rods without distinction between the sections, the gear ratio or the rotational speed may be changed to have a faster feed speed as ever.

Figure 7 is another embodiment of the present invention, while varying the gear ratio of the gear (16 ') of the guide rod for each section while the thickness of the guide rod is configured to obtain a faster rotational force.

In addition to the thickness and gear ratio of the guide bar for each section while connecting the guide rods having a section with the reduction motor and chain belt or timing belt, respectively, giving a faster rotational force for each section will have a faster feed speed as the bar, the present invention Is satisfactory if the structure can increase the feeding speed of the fruit gradually by section.

In addition, the guide rods 12 and 14 are preferably left and right separated in relation to each other having a “V” shape on the front side, but are softly covered on the outer surface when the guide bars 14 and 16 are separated from each other. It may be connected indirectly through the protective tube 10 of the, and when the protective tube 10 is connected to the characteristics of the flexible protective tube 10 can be flexibly cope with the adjustment of the inclination angle, and the space utilization for power transmission is advantageous. One can also separate the left and right by putting a separate protective tube on each guide rod.

In addition, the left and right guide rods may be connected by a joint, but when connecting using the joint, each guide rod can be rotated by using a ball light from the left and right side plates so that the inclination angle of the left and right side plates can be adjusted.

On the other hand, the gears 16 and 18 are connected to the ends of the guide rods, and the guide rods 12 and 14 are rotated in one direction by engagement between the contact gears 20 and 22. (12) (14) When the connection is maintained by the protective tube 10 or the joint, etc., it is advantageous to secure a space for gear installation because the gear is transmitted only by installing a gear to only one of the guide rods selected from the left and right guide rods.

Reduction motor for transmitting power to each guide rod (14, 16) is to have a separate reduction motor for each section when the side plate (4) (6) is configured to be adjustable to have a different angle of inclination separated by section Satisfactory results are obtained by connecting any selected guide rod with a chain belt or timing belt.

However, even if the left and right side plates have different inclination angles for each section, the guide rods are closely connected so as to have a minimum interval without division for each section. By connecting the drive shaft with the reduction motor it is possible to give a rotational force to the entire guide rod with a single reduction motor.

The present invention extends between the pre-processing conveyor of the fruit sorter and the measurement and classification conveyor to loosen the turnbuckle (8) and adjust the inclination angles of the left and right side plates (4) and (6), which are separated by the section, to adjust the inclination angles. (14) (16) to have a proper inclination angle.

At the time of installation, as the thickness of the guide rod constituting the present invention becomes thin, the step between the pretreatment conveyor and the measurement and classification conveyor can be minimized.

In addition, when looking at the angle and rotational speed of the guide rods 14 and 16 for each section, it is determined by the working conditions or the type of fruit (A) to be sorted and the angle of the key cup that the measuring and classification conveyor has. Based on the selector, a total of three stages are suitable for the first stage with a speed of 20m per minute at an angle of about 30 °, the second stage with a speed of 35m per minute at an angle of about 20 °, and the third stage of 45m per minute at an angle of about 10 °. Although the speed is appropriate, this is only presented to explain the operation relationship of the present invention for easy understanding, but not limiting.

After adjusting the angles of the guide rods 12 and 14, the sorting operation is performed by transmitting power to the fruit sorter. The fruit is sorted and removed during the passage of the pretreatment conveyor to form a first stage. When tangled and centered on a dense guide rod, the fruit is arranged in a row due to the large angle between the left and right guide rods and the rotation of the guide rods, while the guide rods rotate independently. It will lead you to take a posture with low potential energy.

Fruits that pass through the first stage are naturally centered on the guide rods of the second stage, which are formed at the same height without any difference, so that they can maintain a stable posture given in the first stage, but the difference in thickness from the first stage guide rods The difference in rotational speed due to the gear boiling causes a gap between the fruits to be conveyed.

Fruits that pass through the second stage are also centered naturally on the guide rods of three stages, which are formed at the same height without any gap, so that they can maintain a stable posture and are transferred after the rotational speed difference that is different from the thickness of the two stage guide rods. The gap between the fruits becomes wider to maintain the interval of about 20-30 mm, which is required for measuring the instrument.

After passing through step 3, the fruit is centered on the key cup of the measuring and classification conveyor adjacent to the rear, and even when centering on the key cup, the step difference between the guide bar and the guide bar is greatly reduced, so that the attitude of the fruit may be scattered when centering. There is no possibility to maintain a given interval between the fruit, and there is no fear of deviation from the center line, the sorting operation by the accurate measurement of the instrument can be made.

After passing through the measuring instrument, when it reaches the classifier according to the measurement result, the tilting of the keyboard cup by the solenoid causes the fruit to fall and collect on the classifier continuously.

As described above, the present invention is rotated at a given speed for each section, which is engaged with each gear, and the guide rod is easy to maintain because there is no fear of change of the rotational force even for long use, and rotates independently with an inclination angle of "V" type on the front. The guide rods are used to quickly arrange the fruits in a row and guide them to take the most stable posture with fine posture correction, so that they can maintain their correct posture at all times. There is no step in between, and it can be installed to be closer to the measuring and sorting conveyor through the guide bar that is thin, and the fruit is centered on the key cup of the measuring and sorting conveyor until the step is minimized so that it can be placed in a stable position. There is no fear of change of posture, interval and centerline of fruit. Classification by grade can increase the confidence in the product, and furthermore, it is possible to improve the work efficiency by increasing the feeding speed by quick posture correction and minimizing the step of the fruit.
