Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a posture inversion sorting apparatus for fruits such as strawberries.
[0002]
[Prior art]
Conventionally, when storing many fruits such as strawberries in a transport container such as a corrugated cardboard box, the top of the plurality of fruits (the flower falling part side) is set in advance with the heels of all the fruits facing down. ) Are adsorbed by a vacuum adsorption pad, moved to a predetermined location in the container, and arranged.
[0003]
For this reason, it is necessary to align the posture of the fruit in advance so that the flower fall part is on as described above. As a conventional automatic posture reversing device, for example, at a position above the middle part of the conveyor Some had nets for posture reversal.
According to this apparatus, when the fruit on the conveyor has the flower drop part up, the flower drop part is slippery, so that it does not get caught on the net, but the fruit is placed with the buttocks up. When transported, the angulated corners and tips of the buttock are caught by the net, so that the fruit can be reversed so that the heel is down.
[0004]
[Problems to be solved by the invention]
However, when a large number of fruits are transported on the transport conveyor in a state where the distance between the front and the back is narrow, the fruits transported immediately after the fruit that is about to be reversed by being caught by the net collide, and the posture reversal action As a result, the reversal rate is poor.Therefore, on the downstream side of the conveyance, a sensor for judging the fruit that has not been reversed is provided, and a sorting unit that eliminates a bad posture is provided. Thus, there is a problem in that the work of reversing the fruit in the bad posture to a predetermined posture is required, the work efficiency is lowered, and the total length of the device for reversing and selecting the fruit posture is increased.
[0005]
The present invention solves these problems, and provides a fruit posture reversing / selecting apparatus which can reverse the posture of fruits with a simple structure, efficiently, and can select only fruits in a predetermined posture in a desired direction. It is intended to provide.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment embodying the present invention will be described. FIG. 1 is a schematic plan view of a fruit posture inversion sorting apparatus, and FIG.
The posture reversal sorting apparatus 1 according to the present invention is configured such that the posture of the cocoon 2 as a fruit conveyed in the direction of arrow A by the first conveyor 3 such as a belt conveyor is the flower falling part 2a (opposite to the cocoon part 2b). The posture is reversed so that the upper side is the upper side, and only the cocoon 2 with the flower drop part 2a on the upper side is sent to a predetermined good product conveyor 4 (such as a belt conveyor). As for the posture of 2, the one with the flower fall part 2a facing up and the one with the collar part 2b facing up are mixed. The flower drop part 2a side of the cocoon 2 is almost flat and the surface is smooth. On the other hand, the cocoon part 2b is a hard part consisting of a plurality of cocoon pieces having pointed tip parts, and is an uneven part.
[0009]
To the end pulley 5 of the end of the first conveyor 3, the start of the inclined plate portion 6a as a posture reversing chute portion 6 is disposed with a step of appropriate height H1, and through the horizontal plate portion 6b It is connected to the front end of the second conveyor 7. The inclination angle θ1 of the inclined plate portion 6a shown in FIGS. 2 and 3 is set as follows. That is, out of the ridges 2 that are tilted down from the stepped portion, when the ridge portion 2b with a small friction is down on the surface of the inclined plate portion 6a, in the same position, in the front end direction of the second conveyor 7. When the flower falling part 2a that can flow and has a large friction falls down and falls along the inclined plate part 6a from the stepped part, the collar 2 rotates due to the large friction and the collar part 2b falls. Thus, the inclination angle θ1 is such that the probability that the posture of the heel 2 is reversed is high, and is determined by experiments together with the height dimension H1 of the step.
[0010]
Therefore, the majority of the ridges 2 that have fallen down by the posture inversion chute 6 are inherited and conveyed at the front end of the second conveyor 7 in a posture in which the flower drop portion 2a is up. This is on one side of the second conveyor 7 is arranged a good article conveyor 4 into a parallel form, the deflection plate 8 disposed in front of the second conveyor 7, persimmon 2 conveyed, the second conveyor 7 While deviating toward the other side, the sheet is conveyed toward an inclined sorting section 9 to be described later.
[0011]
The second conveyor 7 is configured by a belt 12 wound around a parallel cylindrical front end pulley 10 and a conical cylindrical rear end pulley 11. The belt 12 is wound on the large diameter side of the rear end pulley 11 and the first discharge part 13 which is raised toward one side of the second conveyor 7 and the inclination angle is reduced by the belt 12 being wound on the small diameter side. It is comprised by the 2nd discharge | release part 14 which is near the other side and has a large inclination | tilt angle.
[0012]
As described above, when the flange portion 2b is on the lower side, there is little friction, so that the flange 2 with the flange portion 2b on the lower side can rise up the second discharge portion 14 having a large inclination angle. First, it slips in the direction of the first discharge section 13 with a small upward inclination angle, moves to the location of the non-defective conveyor 4 and is adsorbed by the vacuum suction pad of the moving means 15 at the rear thereof, and a predetermined location in a container (not shown) Can be arranged.
[0013]
On the other hand, since the friction is large when the flower drop part 2a is down, the ridge 2 in that state rises up the second discharge part 14 having a large inclination angle and is discharged to the start end part 17a of the return conveyor 17. As shown in FIG. 1, the return conveyor 17 is configured by a belt conveyor or the like configured to return the basket 2 from the terminal end (second discharge part 14) of the second conveyor 7 to the front part. A net 18 as a posture changing means is disposed above the return conveyor 17 in the middle. When the reed 2 with the reed 2b turned up is returned and conveyed by the return conveyor 17, the reed 2b is locked to the net 18 so that the flower fall part 2a is turned up, and this state Thus, it is returned to the front side of the second conveyor 7.
[0014]
The left and right sides of the first conveyor 3, the left and right sides of the posture reversing chute 6, the outside of the non-defective conveyor, the outside of the return conveyor 17, and the boundary between the return conveyor 17 and the second conveyor 7 are respectively Guide rails 20a, 20b, 21a, 21b, 22, 23a, 23b, 23c, 24 are arranged so that 2 does not deviate from the transport path.
[0015]
With the above configuration, the cocoon 2 conveyed by the first conveyor 3 is different from the one with the heel part 2b down and the one with the flower drop part 2a down. From the position of the inclined plate portion 6a of the posture reversing chute 6 from the rotation of the heel 2 due to the step and the difference in frictional force between the heel portion 2b of the heel 2 and the flower drop portion 2a against the inclined plate portion 6a, Most of the heels 2 are inverted so that the heel part 2b with less friction is on the bottom. Next, the basket 2 that has been transferred to the second conveyor 7 is transported to the non-defective part of the first discharge section 13 having a small rising inclination angle at the rear part of the second conveyor 7 with the collar section 2b with less friction slipping down. released towards the conveyor 4 can be selected and so large flower fall portion 2a of the friction is released from the second discharge portion 14 having a large inclination angle up what became below the return conveyor 17.
[0016]
Then, as described above, the heel 2 that could not be reversed to the predetermined posture (the state in which the heel portion 2b is down), when conveyed in the direction of arrow C in FIG. The net 18 as the converting means is engaged with the upward flange portion 2b, and the posture of the flange 2 can be reversed so that the flange portion 2b faces down. Thus, by cyclic posture reversal work and sorting work from the second discharge unit 14 to the first discharge unit 13 as the sorting unit of the second conveyor 7 through the return conveyor 17 having the posture changing means, Eventually, all the cocoons 2 can be discharged by the non-defective product conveyor 4 with the flower drop portions 2a facing upward.
[0017]
【The invention's effect】
As described above, the fruit posture reversal sorting apparatus according to the first aspect of the present invention includes a first conveyor that conveys fruits such as strawberries with their ridges or flower drop parts on the bottom surface, and the first conveyor . between the second conveyor arranged in the conveyor and a serial manner, the posture reversing chute portion and a horizontal plate portion extending from the end of the inclined plate portion and said inclined plate portion having a friction provided, the second conveyor one On the side, a non-defective conveyor that extends in parallel with the second conveyor is disposed, and at the rear of the second conveyor, an inclined sorting section is formed that rises toward the transport downstream side of the second conveyor, and the sorting section Are provided near the one side of the second conveyor and have a small upward inclination angle, and are provided near the other side of the second conveyor and adjacent to the first discharge part. A second discharge part with a large angle. The return conveyor for returning the fruit discharged from the second discharge part to the second conveyor is disposed between the second discharge part and the front part near the other side of the second conveyor, In the upper part of the middle part of the return conveyor, a net is provided to reverse the fruit so that the flower fall part is on the hook part, and the posture reversing chute part is at the end of the first conveyor. On the other hand, it is arranged with a step so that the starting end of the inclined plate portion is on the lower side, and the inclination angle of the inclined plate portion with respect to the horizontal plate portion is the same as that of the fruit with the heel portion down. It is set so that the fruit that flows in the posture and the flower falling portion is turned down is reversed by friction with the inclined plate portion, while the posture reversal is on the front portion near the one side of the second conveyor. The fruit transferred from the chute is transferred to the second conveyor. A deflecting plate is arranged to move closer to the other side, and in the sorting section, the fruit with the heel part down slides from the second discharge section to the first discharge section and is discharged to the non-defective conveyor. The fruit with the flower falling part down is discharged from the second discharge part to the return conveyor .
[0018]
As described above, most of the fruits that have fallen from the end of the first conveyor to the posture reversing chute portion can be reversed to a predetermined posture by the inclined plate portion having friction. And, since the first discharge part having a small upward inclination angle among the upwardly inclined selection part at the rear part of the second conveyor, only the fruit with the heel part on the lower surface can be slid and selected in the direction of the non-defective conveyor, The structure for inversion and sorting becomes extremely simple, and the manufacturing cost can be reduced. In addition, since the non-defective product conveyor is disposed on one side of the second conveyor, the entire apparatus can be shortened.
[0019]
[0020]
Also , the posture reversing chute part is reversed so that most of the fruit is placed with the lower part of the buttock having less friction. And about the fruit which was not able to be reversed to the predetermined posture (state where the buttock was down), the posture of the fruit is locked by the posture changing means in the middle part of the return conveyor. Can be reversed so that the hips are down. Thus, it returns to the front part of a 2nd conveyor via the return conveyor which has an attitude | position conversion means from a 2nd discharge | release part.
[0021]
Moreover, since the larger second emitting section and the upward inclination angle smaller first discharge portion of the tilt angle increases in a rear portion of the second conveyor are adjacent, sepal portion less friction in the first emitting portion becomes lower Repeat the cycle process that can be sorted so that things slide sideways and discharged toward the good conveyor, while those with the lower flower falling part are discharged from the second discharge part to the return conveyor 17 since, also it becomes unnecessary sensors for attitude of the fruit to determine whether a predetermined one is to the effect that the structure of the device is extremely simple and inexpensive.
