KR101932607B1 - A fruit selector that can sort fruits of various sizes and kinds - Google Patents

Abstract

The present invention relates to a fruit selector, and more particularly, to a novel technology for selecting fruits of all sizes and all types such as jujube-shape cherry tomato, jujube, apple jujube, cherry tomato, Japanese apricot, kumquat, and plum by using one fruit selector. According to the conventional fruit selector, since a spacing adjustment of the selection springs is limited, different types of fruits of relatively large size are rarely selected, and since the gap between the selection spring positioned on the side and a selector body is narrowed or widened according to the adjustment of the spacing and position of the selection springs, the fruit is deviated or stuck in the gap. To solve the problems, according to the present invention, selection springs are installed in 6 or 5 rows depending on the size and type of fruits, and the position of the side separation preventing bar, which is adjustably positionable in the width direction on an upper end of front and rear plates of the selector body, is adjusted, so that the gap between the selection springs disposed on the selector body and the side is prevented.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a fruit selector which can sort fruits of various sizes and kinds.

The present invention relates to a novel concept capable of selecting all fruits of various sizes and types using one fruit sorting machine.

Selection of fruits such as jujube tomatoes, jujube, apple jujube, drop tomatoes, plums, kumquat, and plums is an important task to improve the value of the fruit.

Therefore, various types of sorter have been developed and used to determine the fruit grade according to various sorting factors such as size, weight, shape, color, flavor, taste, and scratches of fruit.

Among various kinds of fruit sorters, it is widely used to select fruit according to the size as disclosed in "Patent Registration No. 861742, Name / Automatic Fruit Sorting Device" (hereinafter referred to as "Prior Art 1"). A plurality of sorting springs are employed in the sorting machine 1.

The sorting springs are installed so that the intervals therebetween are gradually widened, so that the sorting springs have a structure in which fruits are sorted from small to large.

At this time, the sorting spring is installed as a closed curve on the main body of the apparatus and rotated. In order to connect the sorting spring long, conventionally, a ring has been formed at both ends of the sorting spring to connect each other.

However, when the sorting spring is connected in this manner, the separating springs do not extend evenly as the connection springs of the sorting springs are spaced by the size of the connection rings of both the springs. Therefore, There arises a problem in that sorting error of the small fruit occurs due to a certain interval.

As a prior art for solving these problems, "Patent Registration No. 1430146, Name / Fruit Separator" (hereinafter referred to as "Prior Art") has been introduced.

Unlike the prior art, the prior art 2 can uniformly connect the sorting springs without a seam interval, thereby preventing a sorting error from occurring due to a seam spacing at a connecting portion of the sorting spring.

 However, in the prior art 2, it is possible to sort fruits of a relatively small size by adjusting the spacing of the sorting springs, but the adjustment of the spacing of the sorting springs is limited, so that it is not possible to sort other kinds of fruits having relatively large sizes.

In addition, due to the adjustment of the interval and position of the sorting spring, the gap between the sorting spring located on the side and the main body of the separator is narrowed or widened, and the fruit is detached through the gap and the sorting is not properly performed. Which causes a problem of inducing a load on the motor.

Further, when the fruit moving in a state of being placed between the sorting springs is not placed in the longitudinal direction of the sorting spring but is placed in the width direction, a problem arises that the fruit is not accurately sorted by size.

In addition, the fixing force of the pulleys and the driven pulleys with the selection springs wound is weak, which causes the flow to the left and right due to the vibration during use, which lowers the transfer force and the sorting power and causes frequent A / S generation.

In order to solve the above-mentioned problems, according to the present invention, a sorting spring is selected in six rows or five rows according to the size and type of fruits, And a gap between the selector spring disposed on the side of the separator and the separating spring disposed on the side of the separator is adjusted while adjusting the position of the installed side separation barrier.

Further, the present invention provides a technique of aligning the alignment sticks provided in the fruit sorting apparatus connected to the upper ends of the front and back plates so that the fruit placed in the width direction is accurately positioned in the longitudinal direction while changing directions.

Further, the present invention is characterized in that the fixing force of the driving pulley and the driven pulley is adjusted by pressing and fixing the threaded bolts threaded through the boss of the driven pulley and the driven pulley to the fixed flat surface formed along the axial direction on the outer peripheral surface of the primary pulley shaft and the driven pulley shaft We will try to find a technique that will greatly enhance this.

According to the present invention, it is possible to select and install the number of the sorting springs in any one of 6 rows or 5 columns, thereby ensuring a wider adjustment width of the interval of the sorting spring, It is possible to select and provide a cost-effective effect.

In addition, by adjusting the spacing and position of the sorting spring, the width of the clearance generated between the front and rear plates of the main body and the sorting spring located on the side can be varied, Thereby preventing the deterioration of the screening force and the reduction of the conveying force, as well as eliminating the troubles of removing the fruit that the worker inserts, thereby reducing the labor force and preventing the overload of the motor, thereby improving the durability.

In addition, the sorting sticks are properly aligned in the lengthwise direction while the sorting sticks are being turned in the course of feeding the fruit misplaced in the width direction between the sorting springs, thereby accurately selecting the fruits according to sizes, The ring effectively eases the impact on the fruit while preventing damage to the fruit, thereby improving the income of the farmer.

Therefore, the side departure preventing bar 30 blocks the gap 1 generated between the front and rear plates 11 and 12 and the sorting spring 20 located on the side, so that the fruit is separated from the gap 1 Thereby preventing a decrease in the selection ability or a reduction in the conveying force, and also provides a special effect of reducing the workforce by eliminating the troubles of removing the fruit entrapped by the worker.

In the present invention, as shown in FIG. 2, six forward and reverse pulleys 23 and six driven pulleys 24 are used to select the sorting springs 20 in six rows in a state in which the front and rear plates 11 and 12 are spaced apart from each other It is possible to sort fruits of a relatively small size according to the kinds of fruits.

In the case where the selection spring 20 is installed in five rows as shown in FIG. 6 by using the five pulleys 23 and the driven pulleys 24, the spacing of the sorting springs 20 is increased, Provides a special effect to select different types of fruits.

The distance between the front and rear plates 11 and 12 of the separator main body 10 and the sorting spring 20 located on the side of the separator main body 10 A technique for smoothly blocking such a width-variable gap 1 even if the width of the gap 1 is variable is further combined.

In order to accomplish this, a plurality of position-adjusting slots 32 are formed in the width direction at intervals along the longitudinal direction of the side departure prevention bar 30, and the position adjusting slots 32 and the front and rear plates 11 The nut 34 is screwed to the fixing bolt 33 passing through the upper plate 13 of the base plate 12.

Therefore, after the fixing bolts 33 are released in a state where the side departure prevention bar 30 is fixed, the front and rear side plates 11 The clearance 1 is efficiently blocked regardless of the width of the clearance 1 which is generated between the separating spring 12 located on the side and the sorting spring 20 located on the side, And a sort of fruit selection.

A discharge chute 40 is provided between the primary pulley 23 and the driven pulley 24 so as to be inclined downward from the front surface of the separator main body 10 and a plurality of partition walls 41 are protruded upward so that the sorted fruits can be separated and discharged by the discharge chute 40 by size.

A plurality of work passages 15 are formed at the lower side of the rear plate 12 so that an operator inserts the hand into the selector main body 10 through the work passageway 15, The support roller 60, the tension roller 70, and the like described later can be easily repaired or inspected.

The present invention further includes a plurality of fruit sorting apparatuses 50 arranged adjacent to the centrifugal pulley 23 for aligning fruit in the longitudinal direction of the sorting spring 20 at the upper end of the sorter body 10 do.

In other words, the fruit which has been misplaced in the width direction between the sorting springs 20 is automatically turned at the moment when one side comes into contact with the sorting stick 55, and is correctly positioned in the longitudinal direction of the sorting spring 20 By automatically aligning, the fruits can be sorted accurately by size.

The alignment stick 55 has a fixing ring 55a at its upper end and a fixing bolt 53 penetrating through the fixing ring 55a and the position adjusting elongated hole 52 formed in the fruit alignment bar 51 The position of the alignment stick 55 can be freely adjusted according to the spacing of the sorting springs 20 as well as the alignment stick 55 can be fixed without any flow by screwing the nuts 54.

A damage prevention ring 55b is formed at the lower end of the alignment stick 55. The damage prevention ring 55b prevents the alignment stick 55 from generating a cutting force such as a blade when the fruit contacts, And the impact is mitigated to effectively prevent fruit damage.

4 to 5, the sorting sticks 55 are located on the upper side of the sorting springs 20 located on both sides with one sorting spring 20 interposed therebetween, And is disposed repeatedly staggered on the adjacent two sorting springs 20 while moving toward the driven pulley 24 from the idling pulley 23 so that the sorting spring The sorting stick 55 is located on the upper side of all of the sorting springs 20 except for the upper and lower sorting springs 20 and 20 to provide a special effect that the fruits that are disturbed during sorting can be properly aligned without fail.

The present invention also provides a new technique for significantly enhancing the fixing force of the idle pulley 23 and the idler pulley 24 that are provided so as to be spaced from each other while moving along the idler pulley shaft 21 and the idler pulley shaft 22, .
