The present invention relates to a multi-selector that can be used for multi-purpose, more specifically, it is possible to select various types of raw materials by simply adjusting the spacing of the sorting holes, and quickly and accurately by size without damaging the skin of the raw materials during the sorting operation. A multipurpose selector capable of sorting is provided.

Generally, fruits such as citrus fruits, oranges, pears, apples, and other agricultural products, such as bulbs such as onions and potatoes, should be sorted by similar size and graded according to their size to increase the value of the product.

Conventional drum-type sorting machine for this purpose is to install about 10 drum-type sorting bins in a row, in front of the sorting box with the smallest sorting hole is installed, and gradually to the rear end installs sorting tanks with larger sorting holes gradually Screening by size.

However, this drum type sorter is a method in which the raw materials placed between each drum and the drum are sorted by being moved to the next drum by the rotational force of the drum. Since the cuticle is often peeled off and damaged, the commodity value drops, and when the wounded fruit is packaged and distributed as it is, the freshness of other fruits is dropped quickly to deteriorate the quality.

Therefore, the above-mentioned drum type sorter can screen citrus fruits and onions that are thick and intact, but it is difficult to select kumquats, plums, mini tomatoes, plums, apricots, potatoes, etc., which have a thin epidermis. Small sized banks, plums, chestnuts, walnuts, etc., long length carrots, cucumbers, sweet potatoes, etc. can not be selected.

In addition, once the sorting holes for each size are installed in the sorting drum, the size of the sorting holes of the drum itself cannot be changed unless the drum is manufactured again. For this reason, the conventional drum-type sorting machine has to have a sorting line in which drums of different sorting holes are installed for each item, thus occupying a lot of place, and excessively expensive facility costs are not efficient.

1 is a fruit sorting device of Utility Model Publication No. 95-13464 filed and filed by the present applicant. When the fruit sorting device shown in the plurality of sorting lines 30 to form a sorting table 31, each sorting hole (32) at the beginning to form a "V" form gradually widening toward the back, the lower part of the compartment A plurality of drop receiving plates 20a, 20b and 20c divided by grades by the base 21 are provided.

However, the sorting device of the line development has a structure in which the sorting line 30 is inclined as a means for moving the raw material from the beginning to the rear of the sorting line 30. In this way, the raw material is introduced into each inclined sorting line 30 through the supply passage 11 of the supply unit 10, and then reaches the position of the sorting hole 32 suitable for its size, until the guide rod of the sorting line falls. Because it is rolling while hitting continuously, this also has a problem that occurs in the epidermal damage degree of the original during the screening process.

In particular, since the sorting hole 32 has a “V” shape as shown in FIG. 1, the articles to be sorted at the respective positions of the drop receiving plates 20a, 20b, and 20c include ① and ② positions, ③ and ④ positions, Positions ⑤ and ⑥ tend to be sorted into the same class even though there is a significant difference in size.On the contrary, items sorted at positions ② and ③, ④ and ⑤ are sorted into different grades even though there is little difference in size. Therefore, there is a problem that can not obtain the reliability for the screening from the consumer.

The present invention was developed in view of the problems of the conventional sorter as described above, the object of the present invention is to move the raw materials of different sizes mounted on a plurality of transport rollers, but the plurality of grade adjustment guides installed for each grade section It is to provide a low-cost, high-performance multi-purpose multi-selector that can easily perform the size selection by grade according to the type of the raw material simply by adjusting the cycle.

Another object of the present invention is to allow the raw materials to be sorted by size to be accurately sorted by almost all of the similar size accurately, low-cost, high-performance multi-purpose multi-purpose that can increase the confidence in the sorting ability by size to retail traders or consumers To provide a sorter.

Still another object of the present invention is to shorten the contact time of the main roller and the guide roller as much as possible during the process of moving the raw material or during the process of dropping the raw material to prevent the impact of the impact or friction on the surface of the raw material. To provide a low cost, high performance multi-purpose multi-selector that can be sorted.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail with reference to the preferred technical configuration and action that can effectively achieve the above object of the present invention.

Figure 2 is a side view schematically showing the entire internal structure of the multi-selector of the present invention, Figure 3 is a plan view showing an example in which the main roller, the intermediate roller and the drop guide roller of the present invention is moved by both chains, 4 is a partial perspective view showing an example in which the main roller, the intermediate roller and the drop guide roller of the present invention are connected by a connecting bar.

A sorting line (S) installed at a predetermined length on the top of the main body 100 to selectively drop the raw materials by size grade during the process of receiving and moving the raw materials supplied from the raw material supply unit A among the configurations of the present invention shown in the figure; A plurality of first to fourth drop guides 101 to 104 installed below the sorting line S to receive and guide the raw materials falling by grade; The point of constituting the sorting machine can be said to be the same as the conventional sorting machine.

A feature of the present invention is a pair provided in parallel on both sides of the main body 100 to continuously rotate the sorting line (S) from the front to the rear of the sorting line (S) by the chain gear 111 on all sides. Circulation chain 110 and;

A plurality of main rollers 120 which are fitted with shafts 121 at both ends of the chain pieces 112 constituting the circulation chain 110 and are continuously installed at predetermined intervals and moved along the circulation chain 110;

One end is inserted into the shaft 121 of each of the main rollers 120, the other end is connected to the hanging bar 130 is hanging down;

A shaft 141 of both ends is inserted into the middle of the connection bar 130 and idling, and an intermediate roller 140 allowing the original to be placed and moved in a space formed between the main roller 120 and the main roller 120;

Both shaft ends 151 penetrate the lower end of the connecting bar 130 and protrude a predetermined length, and the wheel 152 for the revolution is installed at the shaft ends 151, and the raw material is placed between the intermediate rollers 140. Falling induction roller 150; Constitute a sorting line (S),

The wheels 152 of both shaft ends 151 while the drop induction roller 150 passes through the upper portion of the fourth drop guide portion 104 from the first drop guide portion 101 on both sides of the sorting line S. The first to fourth grade adjustment guides 201 to 204 guided in contact with each other are gradually installed in a stepped manner.

Here, when each of the rating adjustment guide installed in the staircase is installed in a fixed type, the sorting hole 300 for each grade formed by the drop induction roller 150 and the main roller 120 to follow when passing each rating adjustment guide Since the size is always a constant state can be selected only items that can be selected to fit the size of the sorting hole (300).

Therefore, the first to fourth grade adjustment guide (201 ~ 204) is preferably installed in a structure in which the height can be adjusted.

In one embodiment for this purpose, the support rod 400 is installed between the rating adjustment guide and the rating adjustment guide and both sides of each of the rating adjustment guide to form a support groove 206 fitted in the longitudinal direction to the support rod 400 When the slide guide is supported while supporting the support rod 400, the height of each grade adjustment guide can be adjusted according to the type of the raw material to be sorted, and the size of the sorting hole 300 can be arbitrarily adjusted according to the degree of adjustment to sort various raw materials. This is possible.

Here, the support rod 400 is formed as a guide rail that is formed with support grooves 206 at both ends, and both ends of each of the grade adjustment guide is a height-adjusting structure that is elevated in the state fitted to the support groove 206 of the guide rail. It may be configured, or may be to form a stepped shape while each grade control guide to the removable structure, as described above, the height adjustment structure of the grade control guide can be modified in various forms by design changes.

In the drawings, reference numeral 200 is a fixed guide installed higher in front of the first grade adjustment guide 201, the fixed guide 200 is intermediate with the main roller 120 connected by a connecting bar 130 Since the raw materials placed on the roller 140 and the drop-inducing roller 150 only need to be moved as they are until they reach the first grade adjusting guide, it is preferable to install them in a fixed type, not in a height-adjustable type.

In addition, any one of the four-way chain gear 111 for rotating the circulation chain 110 is a drive type to which the power of the electric motor is transmitted, and the other is a driven type.

The present invention thus formed first adjusts the height of the first to fourth grade adjustment guides 201 to 204 according to the type of the raw material to be sorted and the size of the raw material to be sorted.

That is, Figures 5a, 5b, 5c is a side view showing in various embodiments the structure in which the grade adjustment guide is mechanically elevated as the raw materials are sorted by grade according to the present invention, Figure 6 is the main roller and the intermediate roller of the present invention And an enlarged side view of a state in which the drop induction roller is operated.

As shown therein, the first grade adjustment guide 201 is adjusted to be lower than the fixed guide 200, the second grade adjustment guide 202 is adjusted to be lower than the first grade adjustment guide, and the third and fourth grade adjustments. The guides 203 and 204 are adjusted to be lowered in turn than the second grade adjustment guide 202 to form a stepped shape that is gradually lowered from the fixed guide 200 to the fourth grade adjustment guide 204.

In this state, when driving the circulating chain 110 caught on the chain gear 111 in all directions, the main roller 120 and the intermediate roller 140 and the drop guide roller 150 connected by the connecting bar 130 are supplied to the raw material supply unit A. Raw material supply part (A) in the space between the main roller 120 and the intermediate roller 140 and the space between the intermediate roller 140 and the drop guide roller 150 while passing through the fixed guide 200 through The raw materials of sizes ① to ④ of different sizes supplied from are mixed together and moved.

That is, the main roller 120 is installed in each connecting bar 130, the shaft 121 is installed in the circulation chain 110 is always horizontally moved to the same height as the circulation chain 110, connection bar 130 The intermediate rollers 140 and the drop induction rollers 150 connected to each other may be rotated up and down about their respective main rollers 120 so that their positions may be changed.

Therefore, when the wheel for revolution only 152 installed on the protruding shaft end 151 of the drop induction roller 150 is guided in contact with the upper surface of the fixed guide 200 located at the highest position, the drop induction roller 150 and the intermediate roller 140 forms a smoothly divided state near the main roller 120 connected to the connecting bar 130 almost horizontally so that the raw materials placed on the drop induction roller 150 is fixed While being passed through the guide 200, the mounted state is maintained as it is without falling off.

Then, the main roller 120 and the intermediate roller 140 and the drop induction roller 150 installed in each connection bar 130 as described above is divided into a gentle angle close to the horizontal induction roller 150 ) And the sorting hole (300) formed at the interval between the main roller (120) to follow is maintained even if the smallest size of the raw material, so even if the raw material is placed on the dividing sorting hole (300) While passing through the 200, there is no fear that the original falls out below the sorting hole (300).

Thereafter, if both idle wheels 152 of the drop guide roller 150 are positioned in the first grade adjustment guide 201 which is slightly lower than the fixed guide 200, the idle wheels 152 of the shaft end 151 thereof. The drop induction roller 150 has a slightly inclined angle from the main roller 120 suspended from the circulation chain 110 while being placed on the first grade adjustment guide 201 at a low position.

When the more inclined state as described above, the raw material placed between the main roller 120 and the drop induction roller 150 has a separation hole 300 consisting of a gap between the drop induction roller 150 and the main roller 120 that follows. Roll toward the pool and gather.

Then, when the more inclined state as described above, the sorting hole 300, which is the interval between the drop induction roller 150 and the main roller 120 that follows it is a little wider, so that the sorting hole 300 The smallest size of ①, which has the size to fall into), falls into the first drop guide, and the larger size of ② ~ ④ is moved to the next level adjustment guide.

Then, when the wheels 152 at both ends of the moved drop induction roller 150 reach the next second grading guide 202, the drop induction roller 150 has the second grading wheels 152 at both ends thereof. Since it goes further down until it is placed on the guide 202, the drop induction roller 150 is further inclined from the main roller 120 suspended from the circulation chain 110.

Then, the separation hole 300, which is the interval between the drop induction roller 150 and the main roller 120 that follows it by the inclined angle is further widened so as to know the selection hole 300 of the gap spaced apart. The object of size ② that fits is dropped to the second drop guide.

In addition, larger than the size of the ③, ④ of the size is moved to the next third, fourth grade adjustment guide in order to repeat the above process between the falling induction roller 150 and the main roller 120 that follows While the sorting hole 300 is slightly widened, the third size adjusting guide 203 selects objects of size ③ in accordance with the variable sorting hole 300, and falls to the third drop guide, and the fourth grade. In the adjustment guide 204, the objects of size ④ are selected and dropped to the fourth drop guide part.

The present invention simply adjusts the height of the first to fourth grade adjustment guide (201 ~ 204) according to the type of the raw material to be selected and the size of the original drop induction roller 150 passes each grade adjustment guide step by step While the size of the sorting hole 300 can be adjusted to a variety of sizes to be sorted by size according to the kind of the raw material, there is a multi-function that can sort various kinds of raw materials with a single sorter.

And in the present invention, when the inclination angle of the main roller 120 and the intermediate roller 140 and the drop induction roller 150 connected to the connecting bar 130 is large, the raw materials placed thereon toward the sorting hole 300 It can be easily rolled up, but if the inclination angle is gentle, the main roller 120 and the intermediate roller 140 and between the intermediate roller 140 and the drop-inducing roller while passing through the fixed guide 200 and each grade adjustment guide There may be a tendency that the raw material placed between the 150 does not collect well toward the selection hole (300).

To this end, in the present invention, as shown in FIGS. 5A to 5C, a plurality of uneven protrusions 205 are formed on the upper surface of the first to fourth grade adjusting guides.

The uneven protrusion 205 gives a predetermined shock and vibration to the drop induction roller 150 when the wheel for turning only 152 of both ends of the drop induction roller 150 is in contact with the upper surface of the grade adjustment guide dropping guide roller 150 ) Will shake and move.

In addition, such a shock and vibration is transmitted to the intermediate roller 140 and the main roller 120 which are connected to the drop induction roller 150 and the connection bar 130 as it is between the drop induction roller 150 between the main roller 120. The raw materials that are placed in are rolled down smoothly by the impact and vibration, and are collected very well at the selection hole 300.

Then, the drop-inducing roller 150 and the main roller 120 and the raw material to form a sorting hole 300 when the raw materials collected in the sorting hole 300 falls into the sorting hole 300 as described above and The shorter the frictional time is, the shorter the skin of the original is not damaged.

To this end, in the present invention, the chain wheel 122 is installed on one shaft 121 of each main roller 120 so as not to interfere with the existing circulation chain 110, as shown in FIGS. The upper chain from the guide 201 to the fourth grade adjustment guide 204 was installed a chain 123 for powering the chain wheel 122.

In this way, the chain wheel 122 of one side of the main roller 120 is moved along the main roller 120 and enters the fixed chain 123, even if the chain 123 is fixed. 122 is rotated (rotating) in one direction (clockwise in the drawing) by the power applied by itself, and when freed from the chain 123, it is free again.

Therefore, the main roller 120 is free of rotation while passing through the source supply unit A and thus the fixing guide 200 does not damage the skin of the original during the movement of the original.

And, from the first grade adjustment guide 201 to send the raw material to the sorting hole 300, the main roller 120 is powered by the chain wheel 122 engaged with the chain 123 is rotated in one direction. In this case, since the raw material placed between the intermediate roller 140 is pushed and rolled, the raw materials are well gathered into the sorting hole 300 without damaging the epidermis with the vibration effect by the uneven protrusion 205.

In addition, the drop induction roller 150 is a free state that is idling by the idle wheel 152, the main roller 120 is a state that is rotated under the power is applied between the main roller 120 and the drop induction roller 150. Of the raw materials placed in the sorting hole 300 of the raw material of the size that can be dropped into the sorting hole 300 is dropped more quickly by the rotational force of the main roller 120 and the revolution of the drop induction roller 150 The damage to the epidermis can be minimized.

In addition, the present invention may be a manual adjustment of the height adjustment of each of the above grade adjustment guide, but is preferably configured to be mechanically performed for ease of use.
