Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shape sorting device for sorting spherical objects such as plums, cherries, plums, apples, and taros according to the size of their outer diameters.・ [-Prior Art] Conventionally, as a sorting machine that classifies the spherical objects to be sorted by dropping them through a gap that gradually expands in the direction of travel, Japanese Patent Laid-Open Publication No. 54-70946 and Japanese Patent Publication No. 59 of Sho. −
The shape sorter disclosed in Japanese Patent No. 24869 is known, and these shape sorters are called double-spacing shape sorters.

However, the method disclosed in JP-A-54-70946 uses a method that has been used for a long time, in which a cloth member attached to the chain 7 is hung from the side wall of a trapezoidal chain rail to form a conveyance belt. Form a gap between the strips of a mold (\/ shape) and run it widening toward the end, and send the object to be sorted across the cloth members on the left and right sides of it. When the gap between the strips becomes larger than the diameter of the object to be sorted, the object to be sorted will be However, the objects to be sorted are not perfectly round or spherical, but are irregularly shaped, and the falling position differs depending on whether they are sandwiched by the major axis, minor axis, or fruit height, so there is a drawback that there is a large sorting error. It is not used much.

・Also, in the method disclosed in Japanese Patent Publication No. 59-24869, the space between the rollers is formed to widen in stages or in a tapered shape, the rollers are rotated in opposite directions, and the objects to be sorted are separated from the gap between the rollers. This method uses a rotating roller to sort objects by dropping them in order, but this method has the disadvantage of damaging the objects to be sorted, so although it was used for taro, it was not used for fruit.

[Purpose of the invention]

The present invention solves the above-mentioned drawbacks, and even if the object to be sorted is not a perfectly round sphere but has an uneven and slightly distorted spherical shape, it can be sorted and the fruit can be damaged. The purpose is to obtain a sorting device that does not require any sorting equipment.

That is, the objective is to obtain a device that automatically sorts fruits by gradually widening the gaps in the conveyance path while conveying the fruits in a fixed orientation, even if the fruits are in the form of irregularly shaped balls. .

[Structure of the invention]

In order to achieve the above object, the present invention uses a vibrating conveyor in the sorting section that conveys the objects to be sorted and drops them from the gap, and the vibrating conveying surface is shaped like an inverted V-shaped (\/ shape) groove. The vibrating conveying surface is provided with a raised member having a pressure inclination in the conveying direction to accelerate the conveying speed and to separate the objects to be sorted by vibration. Adjust the posture of the object, move it forward, and drop it at a position between fc and depending on the size.

At the bottom of the vibrating conveyance path, a receiving box or a drawer conveyor partitioned into classes is provided to sort the materials.

On the other hand, an automatic sorting device was constructed by providing the sorting section (an automatic aligning vibrating conveyor having a V-groove outlet for automatically aligning and supplying the objects to be sorted in a line).

The feature of the present invention is that the conveying surface of the vibrating conveyor is shaped like an inverted V (＼
/ shape) to form a sorting gap that widens toward the end extending in the direction of travel, and on the conveyance surface there is a raised member (for example, a transportation mat of Japanese Publication No. 111354-8954) that accelerates the conveyance speed. ), the objects to be sorted are conveyed with their posture aligned, and the objects to be sorted are conveyed in the direction of travel by slight vibrations of the elastic raised members, so the objects to be sorted can be sorted without damaging them. It is something that can be done.

Hereinafter, drawings showing one embodiment of the present invention will be described.

1 is an automatic alignment supply device, 2 is a sorting vibration conveyor,
Both are electromagnetic vibration conveyors (pie plate feeders)
However, a vibrating conveyor using a mechanical vibrator or an air vibrator may also be used.

The sorting vibrating conveyor 2 is a combination of main components such as a vibrating frame 3, a vibrating plate 4, etc., a plate spring 5, a vibrating device 6, and a vibrating table 7, and is installed on a pedestal 8 via a vibration isolating member 9. This is similar to a known vibrating conveyor.

Reference numeral 10 denotes a receiving box provided for taking out sorted objects 11 for each class, and depending on the embodiment, a drawer belt conveyor 12 may be used instead of the receiving box 10 as a taking out means. - As shown in FIG. 3, the conveyance path 13 for conveying the objects 11 to be sorted is provided with a diaphragm 4 in an inverted square shape (\/ shape), and a raised member 14 for accelerating the conveyance speed is stretched on the upper surface of the vibrating plate 4. It forms a conveying surface 141, and a sorting gap W is opened at the bottom. The sorting gap W is formed so that the starting end 1310 of the conveyance path 1310 and the sorting gap Wo are made smaller, and the ending point 1310 is a sorting gap Wn of 1310, and the sorting gap Wn at the end 1310 is set as a dog, so that it gradually widens in the traveling direction at rfil/1).

The conveyance path 13 is preferably provided in a straight line from the starting end 131 to the terminal end 132, and the conveying surface 141 is similarly formed with the same slope from the starting end to the terminal end.

It is not preferable to divide the conveyance path works 3 into classes and construct them in stages with lower heights. That is, since the objects 11 to be sorted roll and fall onto the sorting gap W during transfer between classes, this is likely to cause injury and poor sorting.

It is preferable that the sorting gap W widens steplessly from Wo to Wn, but in some cases, such as for items with large dimensional differences between one sorting class, the sorting gap W can be extended to Wl, W2, W3, W4, C, etc. , it is also possible to provide a gradual expansion in stages.

As shown in FIG. 4, the automatic alignment and supply device 1 includes a diaphragm 10
A required number of alignment portions 102 formed in the shape of a groove and a supply outlet 103 extending in the direction of movement are provided on the exit side of the sorting vibration conveyor 2, facing the starting end 131 of the conveyance path of the sorting vibrating conveyor 2.

The raised member (transport mat) is appropriately stretched on the upper surface of the diaphragm 101 of the automatic feeding device 1 in a desired pattern, and the objects to be sorted that are widely fed (injected) into the receiving section 104 are separated into one. They are conveyed in the direction of travel, arranged in rows, and automatically supplied to the sorting vibrating conveyor 2.

The operation of the sorting device configured as described above will be explained.

The objects 11 to be sorted, which are supplied in pieces to the receiving section 104 of the automatic alignment and supply device 1, advance in the vibration direction of the diaphragm 101, that is, in the conveying direction, and when they reach the alignment section 102, the objects 11 are separated by arrows at the core. Due to the action of the raised member (transportation mat) inclined in the direction, the transport progresses in a row so as to gradually narrow the conveyance area, and in a row from the supply exit 03 to the sorting vibrating conveyor 2. It is supplied to the starting end 131 of the conveyance path.

The objects 11 to be sorted supplied to the starting end 131 of the conveyance path are vibrated to adjust their posture on a groove-shaped conveyance surface 141 formed in an inverted V-shape by a raised member j14 inclined in the direction of travel of the conveyance path 13. The object is accelerated and advances, and at a position where the gap W formed between the left and right conveying surfaces 141 becomes wider than the object to be sorted 1], the object falls downward and is sorted.

The napped member 14 is made of a highly flexible elastic body, and its elasticity accelerates the vibration of the diaphragm 4 on the object to be sorted 11, so that a conveying speed of 10 M to 20 M/min can be obtained. In other words, while the conveyance speed of a general vibrating conveyor that does not use a raised member is approximately 2M to 6M per minute, the conveyance speed is more than three times that of a general vibrating conveyor that does not use a raised member, and has the same performance as other types of conveyors (for example, chain conveyors). It will be done.

Further, the raised member 14 vibrates and conveys the object 11 to be sorted by its elastic force, so that the object 11 to be sorted has an irregular spherical shape.
It also has the effect of aligning the posture of the body.

Objects to be sorted that fly out of the sorting gap Wn at the end where the sorting gap W is maximum do not fall on the way and are pooled in the receiving box 15 at the tip as large-diameter fruits.

At the lower part of the conveyance section between the starting end 1310 sorting gap WO and the ending end 132 sorting gap Wn along the conveying path 13, a partition plate 16 is used as appropriate according to the desired number of classes to separate the fallen objects 11. 10 receiving boxes or 1 drawer conveyor for each class
Sort into two extraction methods.

As shown in FIG. 6, a plurality of sorting vibration conveyors 2 may be provided in series. When connecting multiple units,
The conveyance path 13 is provided in a straight line from the first sorting vibrating conveyor 201 corresponding to the automatic sorting and supplying device 1 to the sorting vibrating conveyor 202 at the end, and the sorting gap W also has the starting end of the first sorting vibrating conveyor 201 as Wo. , the terminal end of the end sorting vibrating conveyor 202 is defined as Wn, which gradually widens toward the end.In other words, the sorting gaps of each sorting vibrating conveyor 201, 202 are continuously widened toward the end as if they were integrated.

Further, the vibrating plate 4 of the sorting vibrating conveyor can be tilted slightly downward in the direction of movement to increase the conveying speed and improve the performance.

The sorting vibrating conveyor 2 may also be formed into a hanging type vibrating conveyor by providing the vibrating frame 3, the plate spring 5, the vibrating device 6, and the vibrating table 7 above the conveyance path 13 formed by the vibrating plate 4. can.

The present invention has been described above based on the drawings, but all matters contained in the above description and the attached drawings are examples of implementation and do not serve to limit the invention, and do not fall within the scope of the claims. Other different embodiments may be used as long as the content is as described.

〔Effect of the invention〕

Since the present invention is configured as described above, plums, cherries,
Even if the relatively small, spherical objects to be sorted, such as plums and maiden apples, are not perfectly spherical but slightly distorted and irregularly shaped, the vibrating plate and the erect member will cause minute vibrations to adjust the posture and progress. Since the balls are sorted, the balls for class sorting are well aligned. In other words, uniform sorting and sorting can be performed.

Further, since the sorting gap is formed of a flexible raised member, the objects to be sorted are not damaged, and the objects to be sorted are accelerated, so a large sorting ability can be obtained even with a small size.

Furthermore, since the sorting device of the present invention has an extremely simple structure as shown in the drawings, there is no need for maintenance and there is nothing that breaks down. It is easy to handle and can be used for personal use.
