Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] - The present invention relates to a de-drilling device that is suitable for use in fruit and vegetable sorting facilities, particularly for long-shaped articles, such as those shaped like make-in potatoes.

[Conventional technology and problems]

Generally, when sorting and sorting fruits and vegetables of varying sizes, such as potatoes, there is a process of removing small pieces of fruit and stones before feeding them to a sorter.

In the conventional process of removing small beads, a two-point sorting machine (bar conveyor) was used, which had bars shaped like a drainboard and screened out the items through the gaps between the bars.

However, for long, irregularly shaped items such as make-in potatoes that are supplied in an irregular position from the previous process, if the long diameter is hung diagonally over the front and rear bars, they will not fall through the gap between the bars and will be transported to the next process. Therefore, the sorting accuracy was poor, and a problem occurred in which so-called small beads were mixed in.

On the other hand, articles are conveyed using a so-called vertical brush system, in which multiple brush rolls are arranged side by side with their axes facing down in the direction of travel.
There is a device in which a gap is provided between the pair of vertical brushes for removing beads, the article is conveyed by rotating the vertical brushes, and beads are removed from the gap.

However, according to the above-mentioned conventional device, an irregularly shaped and uneven article such as a potato does not travel smoothly between the vertical brushes, and the article becomes a brake, which has the disadvantage that the article is thrown laterally by the rotation of the brush. .

[Purpose of the invention]

The present invention solves the above-mentioned problems and randomly supplies articles with irregular shapes and size differences such as potatoes, and in particular, articles with a longer axis approximately twice as long as the shorter axis such as make-in potatoes. To provide a device capable of pulling out small beads by arranging them in a line in a certain direction without hanging them diagonally.

[Means for solving problems]

The present invention takes the following technical measures to solve the above problems.

In order to align irregularly shaped articles randomly supplied from the previous process in a fixed direction and line them up in a line, an alignment conveyance path accelerates the center of the diaphragm trough in the conveying direction by approximately the width of one article. An alignment vibrate feeder formed in a substantially square shape with raised side parts on both left and right sides serving as an intervening conveyance path, and a conveyor device having a sorting opening extending in the traveling direction with a predetermined width at the end of the alignment conveyance path. will be established.

The opening for the sorting is formed by providing a gap between the two conveyor belts that matches the size of the sorting for small beads.

That is, articles of irregular shape and randomly supplied are arranged in a line in a predetermined direction on the alignment conveyance path and fed to the conveyor device, and the sorting is performed by dropping and discharging small beads from an opening.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below based on the drawings.

1 is a supply conveyor as a pre-process, 2 is an alignment vibrate feeder, 3 is a conveyor device, and 4 is a drawer conveyor, which conveys the articles from which small beads have been removed to the outside of the machine. 5 is an amorphous article.

A supply conveyor 1 as a pre-process supplies irregularly shaped articles 5 at random.

The transport vehicle of this supply conoveer l is determined by the number of vibrate feeders 2 installed, and when multiple vibrate feeders 2 are installed in parallel, the conveyor vehicle of this supply conoveer 1 is set in the middle direction so as to feed the articles 5 approximately equally to each vibrate feeder 2. A conveyor is used that has the function of dispersing and supplying the material almost evenly.

The alignment vibrate feeder 2 has a structure in which a diaphragm trough 23 vibrates by a vibration generator 22 provided on a base 21, and as shown in FIG. Thus, a substantially V-shaped diaphragm trough 23 is formed in which side portions 232a and 232b on both left and right sides of the bottom portion 231 are raised.

Reference numeral 233 denotes an accelerating member, which is formed of numerous elastic protrusions inclined at a certain angle with respect to the vertical line, and is configured such that the vibration of the diaphragm trough 23 accelerates and conveys the article 5 in the direction in which the elastic protrusions are inclined. As shown in Figure 3, the diaphragm trough 23
An accelerating member 233 is stretched so that the upper surface of each is accelerated and conveyed in the direction of the arrow (=).

That is, the bottom part 231 is provided with an accelerating member 233 so as to accelerate in the transport direction by the width of approximately one article 5, forming the alignment conveyance path A, and the side surfaces 232a and 232b are on the side of the alignment conveyance path A. The accelerating member 2 accelerates from an oblique direction and cuts in.
33 to form an interruption conveyance path opening.

In addition, the acceleration member 23 stretched across the side parts 232a and 232b
3 may be stretched in the same direction as the alignment conveyance path A.

The receiving part 234 is a substantially triangular bottom plate provided on the inlet side of the diaphragm trough 23 and is inclined slightly downward in the direction of movement, and the acceleration member 233 is stretched on the top surface in the direction of movement.

FIG. 5 is a partial detailed view of the receiving section 234, in which the articles 5 supplied from the supply conveyor 1 are received entirely inside the diaphragm trough 23, and as they advance, the articles 5 in the center are accelerated toward the alignment conveyance path I. However, as the articles 5 supplied to both sides of the receiving section 234 advance, they are placed on the entrance of the intervening conveyance path and accelerated toward the alignment conveyance path A.

That is, the articles 5 randomly supplied to the receiving section 234 of the alignment vibrate feeder 2 from the previous process gradually move toward the alignment conveyance path A in the center row, and the articles 5 placed on the alignment conveyance path I move in the conveyance direction. They accelerate and move forward, forming a line.

The conveyor device 3 has two conveyor belts 31 arranged in parallel at a predetermined interval at the end of the alignment conveyance path A of the alignment vibrate feeder 2, and an opening 32 is formed for sorting, and the sorting is carried out from the opening 32. The article 5 in the form of small balls is dropped and discharged.

To further explain the conveyor device 3 in detail, 33 is a driven pulley, which is provided at the lower end of the alignment vibrate feeder 3, and a driving pulley 34 is provided at a predetermined position approximately horizontally ahead of the driven pulley 33.

Reference numeral 35 denotes a tension pulley, which is provided below the pull-out conveyor 4 approximately midway between the drive pulley 34 and the driven pulley 33, and the conveyor belt 31 is stretched therethrough.

As shown in FIG. 6, the conveyor belts 31 are stretched parallel to each other with intervals for dropping the small articles 5, and an opening 32 is formed for sorting.

Reference numeral 36 denotes a guide rail, which is designed to follow the cross-sectional shape of the conveyor belt 31 and allows the conveyor belt 31 to slide thereon.

- Also, in the example, two rows of V-belts were used, but -
Rows of V-belts may also be used.

Furthermore, a special chain can be used instead of a belt.

For sorting, the opening 32 is centered on the alignment conveyance path A of the alignment vibrate feeder 3, as shown in FIGS. 6 and 7.
By providing A and B of the guide rails 36 so as to be able to move laterally, the opening width dimension can be adjusted and any sorting can be made to a standard.

A motor 37 drives the drive pulley 34.

The supply conveyor 1 is attached to the small ball removing device configured as described above.
The articles 5 that are conveyed in a random state are arranged in a line in a predetermined direction on the alignment conveyance path I by the alignment vibrate feeder 2 and transferred to the conveyor device 3, and the sorting for sorting is carried out through the opening 32. Small objects, blocks of stone, etc. are discharged and conveyed to the outside of the machine by a pull-out conveyor 4.

On the other hand, articles larger than small beads are conveyed on the conveyor belt 31 and conveyed to a sorting machine for the next process.

The above description and the attached drawings both show an example of implementation, and do not limit the invention, and can be applied to other shaped devices as long as they are within the scope of the claims.

〔Effect of the invention〕

In the present invention, articles that are conveyed in an irregular manner are arranged in a line in a predetermined direction, and the sorted articles are dropped and discharged from the opening, so that the sorted articles can surely face the opening, and especially long make-in potatoes. In such articles, small beads can be reliably removed without being hung diagonally against the opening.

Furthermore, since the sorting is configured so that the opening can be easily adjusted, the standard for removing small beads can be easily adjusted.
