DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor for supplying long fruits and vegetables such as carrots in a row.

[0002]

2. Description of the Related Art Generally, long fruits and vegetables such as carrots, cucumbers, and radishes used in fruit sorting plants such as tangerines are also measured by detecting the outer shape by a CCD camera. Has been required to be delivered. In this case, the conventionally known 1
As an alignment supply device for row supply, for example, a vibrating plate trough having a raised surface of a predetermined length on its surface is transmitted by the vibration of an eccentric drive motor disposed below, and a mass of fruit and vegetables placed on the vibrating plate trough is transmitted. It is a vibrator-type device that moves forward with vibration and separates slightly overlapping fruits and vegetables and feeds them in a single row.

[0003]

However, in this type of automatic alignment and supply device using a vibrator, the transfer speed is extremely slow, and there is a problem in the transfer capability. In particular, in the single-row alignment using the vibrator method, in the case of spherical fruits and vegetables such as tangerines, the overlapping ones collapse sequentially, and the upper fruits and vegetables can be inserted between the lower fruits and vegetables. For long objects such as, these long fruits and vegetables often take a standing posture with an inclined shape,
Smooth single-row supply cannot be expected.

In view of the above-mentioned circumstances, the present invention mainly comprises a belt conveyor capable of high-speed conveyance, a V-shaped conveyor having a belt shape with one of the belts, and gradually decreasing the conveyance speed from the lower conveyor to the upper conveyor. By doing so, an object of the present invention is to provide a conveyor system for supplying and sorting long fruits and vegetables, which solves the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a V-shaped groove is formed at one side of a narrow belt conveyor having a V-shaped arrangement as a whole in a belt conveyor path having a predetermined feeding width. A high-speed belt conveyor is used as the opposite V-conveyor, and several belt conveyors whose speeds are successively reduced are arranged on the inclined upper side of the one high-speed belt conveyor at a continuous inclination, and the entire surface of the inclined conveyor surface is slid down on the sliding surface. The transfer of the conveyed material of the lower speed belt conveyor on the inclined upper side thereof is shifted into the conveyed space of the conveyed material formed on the side of the high speed belt conveyor, and one line is sequentially aligned at the high speed belt conveyor position of the V-shaped groove. Things.

In this case, the high-speed belt conveyor is a belt conveyor having a single conveyed object mounting width.

Further, the slow belt conveyor on the upper side of the slope of the high-speed belt conveyor is a short-length belt conveyor,
The head is used as a collecting and dropping part for the extra transported material.

[0008]

As described above, a V-shaped array is formed by a plurality of (a plurality of) narrow belt conveyors, and the belt conveyor opposed to the V-shaped groove formed at one side position is set to a high speed (fast conveyance speed). Since a plurality of belt conveyors whose speeds are sequentially reduced are arranged obliquely on the upper side of one of the high-speed belt conveyors, the V-shaped groove is formed in a conveyed product (e.g., a long fruit or vegetable) fed to a predetermined feeding width. The transported material on the high-speed belt conveyor part is transported at high speed, and if there is a transport gap between the high-speed transport and the succeeding belt, the transported material on the slightly slower belt conveyor on the upper side of the slope is caused by the inclined surface in this gap. And then slip down. Since the conveyed material on the belt conveyor having a lower speed on the inclined upper portion slides and cuts into the conveyed gap generated in the conveyed material transferred by the slower belt conveyor, the conveyed materials fed over a predetermined width are sequentially transferred to one side. (V
(The mold groove side), and finally aligned in a line on the high-speed belt conveyor of the V-shaped groove.

If there is an extra conveyed object on the high-speed belt conveyor side that cannot be slid and shifted (aligned in a single row), the length of the low-speed belt conveyor adjacent to the high-speed belt conveyor is set shorter. Since the end is open, excess conveyed material falls from the head portion and can be received by a collection conveyor or the like separately arranged below.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

FIG. 1 shows an embodiment of an alignment feeding conveyor apparatus for carrots using a five-row narrow belt conveyor, wherein 1 is an alignment feeding belt conveyor having a feeding width a of a preceding feeding conveyor 2. The belt conveyor 1 is a multi-strip narrow-width belt conveyor and has a V-shaped arrangement as a whole. In this belt conveyor, at least one carrot width (narrow width) forming the V-shaped groove 4 at one side position is set. The two V-facing belt conveyors (disposed at 90 ° angle) are high-speed belt conveyors 3 and 3, and the speed of the V-shaped groove 4 is reduced to the upper side of one of the high-speed belt conveyors 3. 5 are arranged in a continuous inclination, and the belt conveyor 5
A belt conveyor 6 whose speed is further reduced is arranged on the upper side of the belt conveyor, and a low-speed belt conveyor 7 which is slower than the upper side of the belt conveyor 6 is arranged. Further, a guide inclined plate 8 of a predetermined width having the same inclination is laid on the further upper side of the belt conveyor 7, and the sliding conveyor surface of the belt conveyors 7, 6, and 5 including the guide inclined plate 8 slides down the conveying surface. 9, and the arrangement and supply conveyor device 10 which becomes the V-shaped conveyor 1 'in the entire configuration. Reference numeral 11 denotes a guide frame plate that stands on both sides of the V-shaped conveyor 1 '.

In this case, the conveyor length of the belt conveyor 5 adjacent to one of the high-speed belt conveyors 3 and having a reduced speed is set shorter than that of the high-speed belt conveyor 3, and the head 5 a of the belt conveyor 5 is connected to the high-speed belt conveyor 3. And a collecting and dropping portion 24 for surplus carrots that cannot be transferred to.

For laying each belt conveyor, for example, the high-speed belt conveyor 3 hangs a belt body on pulleys 13 arranged in front and rear, and rotates them by a high-speed motor 14 attached to each drive pulley side. In addition, high-speed belt conveyor 3
The lower speed belt conveyor 5 adjacent to the inclined upper portion is also hung on the pulleys 15 at both ends, and is rotated by the motor 16 at one pulley 15 end. Belt conveyor 6 with lower speed
Are driven by a motor 18 on the pulleys 17 at both ends, and the outer low-speed belt conveyor 7 is also driven by the motor 20 on the pulleys 19 at both ends. In the two high-speed belt conveyors 3, a non-slip 3a is provided on the surface of the lower high-speed belt conveyor 3 to be used for conveyance.

Next, the operation will be described. First, carrots (long fruits and vegetables) A are fed out to the full feeding width by the feeding conveyor 2 at the preceding stage, and the V-shaped conveyor 1 'at a position one stage lower from the end of the conveyor. And supply conveyor device 10
It is fed down to.

Here, in the carrot A group that has fallen over the feeding width a, V is located at one side of the V-shaped conveyor 1 '.
The carrot A placed on the mold groove 4 is conveyed forward at high speed through the groove because the V-shaped groove 4 is composed of two high-speed belt conveyors 3. In this case, the high-speed belt conveyor 3
Since the carousel A has a narrow belt conveyor structure for carrying one carrot A, the carrot A at the position of the V-shaped groove 4 is sent in earlier than the carrot A that falls later, and the carrot A of the succeeding fall is separated and appropriately separated. The transport gap a is formed.

Here, among the carrots A that have fallen over the feeding width a, the carrots A that are fed on the adjacent belt conveyor 5 that is slightly above the V slope of the high-speed belt conveyor 3 and that is slightly slower are positioned above the high-speed belt conveyor 3. Since the belt conveyor 5 is inclined and the belt surface is inclined and the sliding surface 9 is conveyed, the carrot A itself on the belt conveyor 5 is moved forward and slid downward (displacement) by the force, and the speed is increased. The carrot is conveyed so as to be close to the carrot A on the side of the belt conveyor 3. For this reason, if there is a transport gap a in the carrot A group transported by the high-speed belt conveyor 3, the transport gap a
Then, the carrot A on the side of the belt conveyor 5 slips into an interruption state. The interrupted carrots A are arranged in a line during transportation.

That is, since the lower belt conveyor has a higher conveying speed than the upper belt conveyor, the carrot A on the upper slant is conveyed by the conveyor itself and the conveying gap a occurs in the lower belt conveyor. It will slip below. Further, since the width of the high-speed belt conveyor 3 is set to one width of the long fruits and vegetables, a plurality of long fruits and vegetables are not conveyed while being overlapped on one high-speed belt conveyor 3.

In the following, the carrot A placed on the belt conveyor 6 having a slower conveying speed than the belt conveyor 5 has the conveying gap a because the carrot A conveyed by the belt conveyor 5 shifts to the high-speed belt conveyor 3 in the same manner as described above. When it is formed, it slides into this transport gap a.
Further, the carrot A placed on the low-speed belt conveyor 7 also slips when the conveyance gap a is formed in the belt conveyor 6 on the lower slope, and shifts while being sequentially conveyed downward.

Further, the carrots A that accumulate on the fixed guide inclined plate 8 installed on the inclined upper side of the low-speed belt conveyor 7 are made of iron plate and have a flat sliding surface. When the conveyance gap a is formed in the low-speed belt conveyor 7 on the lower side of the slope by rolling or skidding as described above (see FIG. 4).

In this case, the high-speed belt conveyor 3 is still at the end position of the belt conveyor 5 which rotates a little bit slower.
If there is an excess carrot A that cannot be shifted to the side, the carrot A falls directly below the open collection dropping portion 24 at the end of the head portion 5a of the belt conveyor 5, and is separately set below the collection conveyor or collection box. (Not shown).

Further, in the figure, reference numerals 21, 22, and 23 denote a fixed belt feeder having the same belt width and inclination laid at the conveying end of the slower belt conveyor 6, the lower speed belt conveyor 7 and the guide inclined plate 8, respectively. Unnecessary extra carrots A are fed by inertia from the end of each conveyor and guided to the collection conveyor or collection box.

The carrot A placed on the high-speed belt conveyor 3 is supplied with a higher speed V car laid forward in the next step.
The carrot A group arranged in a line by the high-speed belt conveyor 3 is further separated at a fixed interval (not shown) by moving to the mold belt conveyor 25 (see the dashed line in FIG. 1). The transport shall be compatible with the measurement of the measuring device.

[0023]

As described above, the conveyor for aligning and supplying long fruits and vegetables, etc., according to the present invention, as a whole, is a high-speed belt conveyor in which the belt conveyor at the V-shaped groove position is a V-shaped multi-strip narrow belt conveyor. On the upper side of one of the belt conveyors, several belt conveyors whose speeds are gradually reduced are arranged in a continuous inclination, and the entire area of the inclined conveyor surface is set as a sliding conveyance surface. (Including high-speed belt conveyors) Automatically slips into the gap between the groups of conveyed objects that can be conveyed on the belt conveyor side with the slower conveying speed on the upper side of the slope, and finally becomes one row on the high-speed belt conveyor with V-shaped grooves. Will be aligned. That is, since the alignment and supply conveyor device forcibly rotates a high speed belt conveyor and a plurality of belt conveyors (multi-strip type belts) whose speeds are sequentially reduced by a motor disposed at any one of them, a conventional vibrator is used. This makes it possible to perform extremely high-speed single-row alignment as compared with the vibration-type alignment operation, and to adjust the speed of each conveyor. In this case, the belt width is a width on which one long fruit and vegetable such as a carrot is placed, so that the transported product is most suitable for long fruits and vegetables in general as well as citrus fruits such as oranges (there is no overlapping transport). In addition, since the present invention employs the arrangement of narrow multi-strip belts, the present invention has an advantage that the device can be used for a long period without failure or breakage.
