[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crop sorting and conveying device configured to sequentially carry and convey crops to be conveyed, such as carrots, radish and other root vegetables, and send them to the next step in a predetermined posture. For the selection of crops provided with a carry-out section for placing 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 transporting apparatus, conventionally, for example, locking projections are formed on the outer peripheral surface of an endless rotary belt at a predetermined pitch, and the transported crops are sequentially placed by the locking projections. One that is stopped and placed and conveyed one by one, or a pair of left and right endless rotation bands that support freely rotatable rollers at a predetermined pitch and one crop is produced between each roller. It is conceivable that the apparatus is placed and conveyed, and the conveying speed is always set to be constant.

[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 after the automatic sorting and sorting based on the measurement results. 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 possibility that crops may accumulate and become clogged during transportation, and there is room for improvement.

An object of the present invention is to solve the above-mentioned problems and to provide a carrying device which can carry the crops one by one without fail, and can carry the goods smoothly without clogging.

[0006]

According to a characteristic configuration of the present invention, in the crop sorting and conveying apparatus 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 drive mechanism is provided in which a plurality of carriers configured in an inclined position are located in a lower position toward the lower side of the conveyed crops in a line along the conveying direction of the conveyed crops, and each conveyer is vertically moved at a predetermined pitch. A crop that detects the transport transfer amount of the transported crop in this sequential feed placement transport device by setting the drive timing so that adjacent transport bodies move up and down in a contradictory manner while being provided An amount detecting means is provided, and an unloading speed control means for changing and controlling the carrying speed of the unloading section is provided based on the detection result of the crop amount detecting means.

[0007]

In the progressive feeding device, each of the above-mentioned carriers moves up and down, and the crops move while the mounted crops are sequentially transferred to the lower carrier by the tilted posture of the crop-mounting surface. go. 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, the vertical drive of each carrier only needs to consider the timing of movement of adjacent ones, and a simple drive structure is sufficient. In addition, when the transported crop temporarily stays, the transport amount of the transported crop in the sequential feeding and placement transport device increases, which is detected by the crop amount detection means, and the transport speed of the unloading section is detected. For example, by slowing down, the feeding amount of the transported crops to the sequential feeding and placement transporting device is limited and clogging is prevented.

[0008]

As a result, the conveyed crops can be reliably sent out one by one to the subsequent process, and the conveyed crops can be prevented from accumulating and clogging during the conveyance, which is smooth. It became possible to continue the transportation.

Embodiments will be described below with reference to the drawings. FIG.
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 transporting section 4 (an example of a forward transporting section) that sequentially sends the transported crops A sent out from the transporting end section to the next process one by one, and in a predetermined posture, and the transported crops sent out from the alignment transporting section 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 unloading section 3 includes an unloading conveyor 11 in which locking protrusions 10 are formed at a constant pitch on an outer peripheral portion of an endless rotating belt 9 wound around a pair of pulleys 8, 8. It is arranged so as to face the bottom from one side of the hopper 2.
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 the same as 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 sent from the carry-out section 3 through the guide chute 19 moves along with the upward movement of the transporting body 15, and the crop mounting surface 15 in the inclined posture.
Due to a, the transfer object 15 is transferred to the transfer body 15 on the lower side in the transfer direction, and the transfer crop A is transferred by sequentially repeating such transfer transfer. At this time, the transported crop A, which is placed on the transporting body 15 moving downward and is not yet 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 separated. Is surely 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.

Further, a crop amount detecting means for detecting the transport amount of the transported crop A in the aligning and conveying section 4 is provided.
Based on the detection result of the crop amount detection means, the carry-out section 3
Ejection speed control means is provided for changing and controlling the conveyance speed. More specifically, as shown in FIGS. 1, 2 and 4, the light emitted from the light emitter 20a from the upper side through the gaps between the carriers 15 is passed, and the light receiver disposed on the lower side. An optical sensor S is provided as a crop amount detecting means for detecting the amount of the transported crop A based on the light blocking state so that the light is received by 20b, and a control device 21 as an example of the carry-out speed control means is provided. Counting the number of times the light is cut off from the detection signal of the optical sensor S, calculating the amount of conveyance of the conveyed crop A, and controlling the rotation speed of the drive electric motor 22 of the unloading unit 3 based on the calculation result. It is configured to do. In other words, when the transport amount of the transported crop A in the aligned transport section 4 increases, the transport speed of the unloading section 3 is slowed to prevent the transported crop A from staying and to prevent the transport obstruction due to clogging. is there.
