BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device for selecting crops, which is configured to sequentially carry and convey crops to be conveyed such as carrots, radish and other root vegetables, and send them to the next process in a predetermined posture. For the selection of crops provided with a carry-out section for carrying out and carrying out the carried crops from the storage section, and a sequential feeding and carrying apparatus for sequentially sending the carried crops sent from the carry-out section one by one to the next step. Concerning a carrier device.

2. Description of the Related Art In the above-mentioned crop sorting and conveying apparatus, conventionally, in the above crop sorting and conveying apparatus, conventionally, for example, locking projections are formed at a predetermined pitch on the outer peripheral surface of an endless rotating belt to cover the crops. A structure in which the transported crops are sequentially placed and locked by the respective locking projections and placed and transported one by one,
Alternatively, it is conceivable that a pair of left and right endless rotation zones is supported by rollers that are freely rotatable at a predetermined pitch, and one crop is placed between each roller and conveyed.

[0003]

In the conventional structure as described above, the crops are sequentially placed and conveyed one by one, and the weight and length of the crops are measured, and the automatic sorting and sorting based on the measurement results are performed. It was sent to the work process to enable automatic selection of this type of crop.

However, in the above-mentioned conventional structure, it is not always the case that the crops are surely placed and guided one by one in the predetermined posture between the above-mentioned locking projections and the respective rollers. There is a high possibility that troubles such as a case where two or more pieces are placed on the protrusion or a case where the crop is not placed are generated,
Further, in the latter conventional structure, there is a great possibility that the crop is placed over a plurality of rollers and the like.
It has been impossible to reliably place and convey one by one with a predetermined pitch. In addition, there is a risk that crops will accumulate during transport and become clogged, resulting in damage.
There was room for improvement.

The present invention solves the above-mentioned problems and enables the crops to be transported reliably and efficiently one by one, while the damage to the crops can be suppressed as much as possible. The present invention is to provide a transportation device for sorting.

[0006]

The first aspect of the present invention is characterized in that, in the crop conveying device described at the beginning, an upper crop placing surface having a width substantially the same as the width of the conveyed crop is provided. , A plurality of conveyors arranged in parallel in the conveying direction of the conveyed crops, which are arranged in a downward direction toward the lower side in the conveying direction, and a drive for vertically moving each conveyor at a predetermined pitch Along with the mechanism, the drive timing is set so that the adjacent carriers move up and down in a contradictory manner, and the sequential feeding and placement transporting device is configured. The point is that a surface material made of a soft material is attached.

A characteristic configuration of the second invention is that each of the conveyors is inclined along the conveyance width direction, and a cushioning elastic body is attached to an end of the crop mounting surface on the lower side of the inclination. In point.

[0008]

According to the characterizing feature of the first invention, in the sequential feeding apparatus, each of the transport bodies moves up and down, and the placed crops are sequentially transported by the crop mounting surface of the transport body on the lower side. The crops move while moving to.
Since the width of the carrier is almost the same as the width of the crop, the crops that are vertically stacked are collapsed and leveled by repeating the feeding operation as described above. Only individual crops are placed. As a result, even when a plurality of crops to be conveyed are superposed and sent in from the superior side of conveyance, one piece is always sent to the next step at the end of the conveyance. In addition, since a surface layer material made of a soft material that gives slip resistance to the transported crops is attached to each crop mounting surface, the transported crops roll over and move up and down during the transport operation as described above. There is little bounce due to, and the posture is easy to stabilize. In addition, the vertical drive of each carrier only needs to consider the timing of movement of adjacent ones, and a simple drive structure is sufficient.

According to the characterizing feature of the second invention, in addition to the above-mentioned action, since the conveyors are inclined in the conveyor width direction, a plurality of overlapped crops to be conveyed are laterally displaced and collapsed and smoothed during the conveyance. Each piece can be separated more reliably, and when the conveyed crop falls from the lower side of the slope of the conveyor to the reducing device, etc., it is possible to prevent damage to the corners of the end due to the vertical movement of the conveyor. It can be effectively blocked.

[0010]

[Effects of the Invention] Therefore, although the transported crops can be reliably delivered one by one to the subsequent process by the rational structure improvement, the automatic selection work of this kind of crops is performed in a state where the crop damage is small. This makes it possible to improve the work efficiency by reducing the risk of damaging the crop even if the transport speed is increased.

Embodiments will be described below with reference to the drawings. Figure 6
Shows an automatic crop sorting apparatus. This sorting device includes a carry-out section 3 and a carry-out section 3 for locking the carried crop A and carrying it out obliquely upward from a hopper 2 (an example of a storage section) for storing a large number of carried crops such as carrots. Alignment transport unit 4 (an example of a sequential transport device) that sequentially feeds the transported crops A sent from the transport terminal end to the next process one by one, and in a predetermined posture, the transported crops sent from the alignment transport unit 4. It includes a sorting section 7 which receives and supports A, measures the weight of each piece, and sorts and collects the plurality of collecting sections 6 corresponding to each weight rank based on the measurement result.

The carry-out section 3 has a carry-out conveyor 11 in which locking projections 10 are formed at a constant pitch on the outer peripheral portion of an endless rotary belt 9 wound around a pair of pulleys 8, 8, and the starting end thereof is The hopper 2 is arranged so as to face the bottom from one side of the hopper 2, and the transported crop A is placed on each of the locking projections 10.
Are arranged side by side and carried out one by one. Further, the sorting unit 7 rotates the conveyed crops A fed one by one in a posture along the same direction as the carrying direction of the carry-out unit 3 and the aligning and carrying unit 4, and the endless turning chain 1
While being placed on a plurality of trays 13 attached to 2 and transported, the weight of the trays 13 is measured, and the transported crop A having a weight corresponding to each weight rank is based on the weighing result of the weighing device. When approaching, it is configured to fall and be collected by the collecting section 6 for the weight rank via the guide chute 14.

The aligning and conveying section 4 is configured such that an upper crop placing surface 15a having a width substantially equal to the width of the conveyed crop A is inclined so that the lower side in the conveying direction of the conveyed crop A is located downward. A plurality of the above-described transport bodies 15 are arranged in parallel along the transport direction of the transported crop A, and a drive mechanism 16 for moving each transport body 15 up and down at a predetermined pitch is provided, and adjacent transport bodies 15 are contradictory to each other. The drive timing is set so as to move up and down. That is, as shown in FIG.
A plurality of transport bodies 15 are arranged in parallel along the transport direction, the odd-numbered transport bodies 15 are configured as a first group so as to be integrally driven to reciprocate up and down at a constant pitch, and the even-numbered transport bodies 15 are The two groups are configured to be integrally driven to reciprocate vertically. Then, each carrier 15
The crankshaft 17 is provided below the
7, each carrier 15 is interlockingly connected via each crank rod 18, and when the first group of carrier 15 is moving upward, the second group of carrier 15 is moving downward. The drive timing is set so that the drive mechanism 16 is configured.

Therefore, the transported crop A fed from the unloading section 3 is moved downward by the upward movement of the transport body 15 by the crop mounting surface 15a in the inclined posture.
Therefore, the transfer of the crop A to be transferred is carried out by repeating such transfer transfer in sequence. At this time,
The transported crop A, which is placed on the transporting body 15 moving downward and before being transferred to the next transporting body 15, is received and supported by the front surface of the next transporting body 15, so that the transported crop A is reliably separated. Done. Moreover, since the loading width of each carrier 15 is almost equal to the width of the transported crop, when such transfer movement is repeated a plurality of times, the transported crops A having two or more overlaps are leveled one by one. At the transport end portion, the sheets are reliably delivered one by one.

As shown in FIG. 5, the carrying width of each carrying body 15 is formed wider at the carrying start end portion, and is gradually narrowed toward the carrying end portion side. Only one transferred crop A is placed on 15 and, as shown in FIG. 2, each transfer body 15 is inclined along the transfer width direction and overlapped with the transfer. The transported crops A are sequentially laterally displaced to be placed one by one.

A guide belt, which rotates around a vertical axis that moves at substantially the same speed as the transport speed and abuts on the transported crop A, is provided at the high-level side lateral portion of each transport body 15 in the transport width direction. 20
Are arranged over the entire area of the transport path. or,
A guide chute 19 that guides the conveyed crop A sent out from the carry-out section 3 to a high-level side portion at a wide conveyance start end portion of the alignment conveyance section 4 in a posture along the placement conveyance posture of the conveyance body 15. Even when a plurality of conveyed crops A are delivered from the carry-out conveyor 11 in an overlapping manner, the guide chute 19 supplies the crops A to the starting end of the aligning and conveying section 4 in a state in which the overlapping is broken. Configured. Further, at a position on the lower side of the slope of the transfer entrance, the elasticity of gradually changing the posture is guided by the guide chute 19 and acts on the transported crop in a posture in which the longitudinal direction is along the transport direction, that is, the vertical posture. The guide 21 is provided at a predetermined angle with respect to the transport direction. Further, a reduction belt 22 that receives the overflowed transported crops and returns them to the unloading section side is disposed on the low-level side lateral portion of each of the transport bodies 15 in the transport width direction.

Then, a surface layer material 23 made of a soft material for imparting a slip resistance to the transported crop is attached to the crop mounting surface 15a in the lower inclined region of each of the transport bodies 15. More specifically, as shown in FIG. 4, the surface layer material 23 is formed by implanting a large number of small projections 25 made of a soft resin on the surface of the sheet 24 like a so-called artificial grass, and having apexes. It is attached to the lower side of the slope from a position slightly lower than that. Therefore, when the conveyed crop has a vertically long posture in which the conveyed crop is placed over a plurality of conveyers at the beginning of conveyance, the elastic guide 21 effectively acts due to the sideslip. Further, a cushioning elastic body 26 is attached to an end portion on the lower side of the slope of each crop placing surface 15a. That is, as shown in FIG. 2, by laterally inserting and press-fitting into the opening at the lower end of the inclined portion of the conveying body 15, the conveyed crop 15 is prevented from being damaged by the vertical movement of the conveying body 15 when falling. is there.

[Example 1] The material of the surface layer material 23 is not limited as long as it is a soft material such as a rubber plate having a large frictional resistance, which gives slip resistance to the transported crop.

[Second Embodiment] As shown in FIG. 3, the cushioning elastic body 26 provided at the inclined lower side end of each crop placing surface 15a is attached and attached from the upper side of the carrier 15. It may be one. At this time, if the end portion of the carrier 15 is formed with a notch step portion 27 so that the upper surface thereof is substantially flush, the carrier becomes smooth.
