[Industrial application]

 The present invention relates to a transportation device for sorting crops such as carrots, radish and other long vegetables, and more specifically, a horizontal conveyor for laterally placing and transporting the crops on the bottom of a storage part for storing the crops. The present invention relates to a crop conveying apparatus for providing crops, which is provided with a pick-up conveyor that sequentially receives and locks the conveyed crops sent out from the end portion of the lateral conveyor, and places and conveys the crops obliquely upward.

[0002]

[Prior Art]

 In the above-described crop sorting and conveying apparatus, conventionally, the upper side of the conveying path of the lifting conveyor is set to an open state so as not to obstruct the conveyance of the crop.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, the postures of a large number of crops stored in the storage section are not fixed, and the conveyed crops placed and conveyed by the transverse feed conveyor have their longitudinal directions orthogonal to the conveying direction. It is not always conveyed in a posture along the conveying direction, and the longitudinal direction may be in a posture along the conveying direction. It will be placed in a vertical position and transported. Then, when conveyed to the upper position, the conveyed crop in an unstable posture may fall downward due to vibrations etc. accompanying the conveyance, and the crop may be damaged by the collision of the fall. , There was room for improvement. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention is that in the transportation device for selecting crops described at the beginning, an elastic cover body is provided above the transportation route of the lifting conveyor to cover the transportation route, and the transportation start end side of the cover body is provided. It is in the point that it is involved and bent.

[0005]

[Action]

 A horizontal feed conveyor is provided on the bottom of the storage section where many crops are stored, and the crops are fed horizontally in the loaded state, and are sequentially transferred to the lifting conveyor from the transport end. When the transported crops locked and placed by the lifting conveyor are placed in an upright position such that the longitudinal direction of the transported crops is upward, such transported crops are rolled up and bent into an elastic cover. It is brought into contact with the start end of the body and the locked state is released, and it falls into the reservoir, or is guided to fall sideways. At this time, the abutting part is bent with an elastic body involved, so that the crop is not damaged. Even if a shorter transported crop is transported in the vertical posture as described above, since the upper part of the transport route is covered by the elastic cover, such an unstable transported crop may occur. Less likely to fall down.

[0006]

[Effect of the device]

 Therefore, it is possible to effectively carry out the work from the storage area with less risk of damaging the crops, and to perform the automatic sorting work in the subsequent process smoothly.

【Example】

 Embodiments will be described below with reference to the drawings. Fig. 3 shows an automatic crop selection system that picks out carrots, radish and other crops one by one from the storage area, weighs them, sorts them by weight rank, and collects them. This sorting device includes a storage hopper 1 for storing a large number of crops, a carry-out conveyor 2 (an example of a lifting conveyor) for sequentially placing and carrying out crops from the storage hopper 1, and a carried-to-carried crop C. Sequential feed placement / transportation device 3 that sends out to the subsequent process, and the transported crop C sent out from this sequential placement / loading transport device 3 is weighed while being placed and transported, and selectively sorted into a plurality of collection tools 4 by each weight rank. It is provided with a weighing and sorting device 5 for collection.

In the storage hopper 1, a flat belt type bottom conveyor 41 (an example of a lateral feed conveyor) is provided at the center of the bottom surface, and bottom surface side portions 1a and 1b located on both sides of the flat belt type bottom conveyor 41 are provided in an inclined posture for storage. The crops are configured to be rolled and guided on the bottom surface conveyor 41, and the crops C to be conveyed are transferred from the end portion of the bottom surface conveyor 41 to the conveyance conveyor 2.

As shown in FIGS. 1 and 2, the carry-out conveyer 2 winds an endless rotary belt 7 around a pair of upper and lower pulleys 6 and 6, and the outer peripheral surface of the endless rotary belt 7 is located. The locking projections 8 are formed at a constant pitch, and the transport start end is arranged in the storage hopper 1 through a cutout formed on one lateral side so as to face the bottom. The transport crops C are placed one by one in a horizontal direction and are transported obliquely upward. Further, vertical walls 9, 9 are formed on both left and right sides of the carry-out conveyor 2 to prevent the transported crop C from falling laterally outward. In order to prevent the placed crops from falling from the upper side of the transport path toward the storage hopper 1, a transparent synthetic resin protective sheet 10 (covering the elastic cover body) covering the upper side of the transport path of the carry-out conveyor 2 is provided. One example) is installed. At the starting end side of the conveyance of the protective sheet 10, it is wound in an arc shape and bent and fixed with a screw through the abutment plate 11 so that the crop is erroneously placed in an upright position on the locking projection 8 and is conveyed. In doing so, the posture is changed by contacting the arcuate bent portion 10a. Further, the pad plate 11 is erected and connected over the left and right vertical walls 9, 9 so that when the large number of crops is thrown into the hopper 1, the vertical walls 9, 9 are bent and deformed inward. To prevent it.

As shown in FIGS. 7 and 8, the weighing / sorting device 5 biases the crop mounting tray 13 to one side in the conveying direction at a predetermined pitch over a pair of left and right endless rotating chains 12, 12. The mounting engaging portion 14 is rotatably installed around the horizontal axis at a fixed position, and the mounting engaging portion 14 formed on the opposite side of the installed portion is mounted and locked on the guide rail 15 arranged along the endless rotating chain 12. Then, the predetermined mounting posture is maintained. The guide rail 15 is provided with a movable rail 15a at an appropriate position, the movable rail 15a is attached to one side of the balance arm 16, and an electromagnetic solenoid SL is provided on the other side of the balance arm 16 to be described later. The movable rail 15a is configured to be driven to swing downward by being controlled so as to operate. That is, a weighing unit 42 that receives the transported product C sent from the sequential feeding device 3 and measures its weight is provided at the starting end of the transportation, and the electromagnetic solenoid of the weight rank corresponding to the control device 43 based on the weighing result. It drives SL. The weighing unit 42 has the weighing sensor SE disposed below the swinging end of a mounting member 44 that is swingably supported around the horizontal axis of the frame, and also mounts the mounting member 44 in synchronization with the transport speed. An electromagnetic solenoid SL for oscillating upward to discharge the crop to the tray 13 is provided after the weighing operation at a constant cycle. Then, the trays 13 of the corresponding weight ranks rotate downward, and the picked-up crops 4 are arranged side by side along the conveyance direction of the endless rotation chain 12 via the lower guide chute 18 in parallel with each other. Of these, the collection tool 4 of the corresponding rank is configured to fall and collect. In addition, the transported crop C that has not fallen on any of the collecting tools 4 is configured to be guided from the terminal end of the transportation to a storage tool 20 arranged in parallel with each of the collecting tools 4 via a guide chute 19. There is.

As shown in FIGS. 4 and 5, the progressive feeding device 3 has an upper crop placing surface 21a having substantially the same width as that of the transported crop C, and the lower side of the transported crop C of the transported crop. A plurality of conveyors 21 arranged in an inclined posture located below are arranged in parallel along the crop conveying direction, and a drive mechanism 22 for moving each conveyor 21 up and down at a predetermined pitch is provided, and each adjacent conveyor 21 is provided. The drive timing is set so that the carriers 21 move up and down in a contradictory manner. That is, as shown in FIG. 6, the odd-numbered transport bodies 21 are configured to integrally reciprocate up and down at a constant pitch as a first group, and the even-numbered transport bodies 21 are integrally configured as a second group. A pair of T-shaped oscillating members 24, 24, which are configured to reciprocate up and down at a pitch and reciprocally oscillate by an eccentric crank mechanism 23, are provided at a lower position of each carrier 21, and the first group of carrier The connecting arm 24a connected to the body 21 is pivotally supported on one side of the balance swinging ends of the swinging members 24, and the connecting arm 24a connected to the second group of transport bodies 21 is connected to the other side. The drive mechanism 22 is configured by setting the drive timing so that the first group and the second group move up and down in a contradictory manner. In addition, the conveyance width of each conveyor 21 is formed to be wider at the beginning of the conveyor and gradually narrower toward the end, so that only one crop is placed on the conveyor 21 at the end. Is configured to be placed, and each of the transport bodies 21 is slightly inclined along the transport width direction so that the transported crops C overlapping with the transport are laterally displaced and placed one by one. is there. Then, the conveyance width of the two conveyance bodies 21 at the conveyance end position, that is, the width in the direction orthogonal to the conveyance direction is set to be larger than the conveyance width of the conveyance body 21 on the higher side than that, and the conveyance at the end is performed. The body 21A is formed in a thin plate shape, and a sheet-like elastic body 40 is arranged in a cantilevered manner at the delivery position on the lower side of the transport body 21A at the end of the transport body 21A. It is prevented from joining.

The conveyance start end portion is conveyed through a guide chute 25 that guides the conveyed crop C that has fallen from the end of the carry-out conveyor 2 in a posture in which the conveyed crop C follows the placement conveyance posture of the conveyance body 21. It is configured so as to be delivered to a portion on the upper side of the slope of the body 21, and the overlapped conveyed crops C are supplied in a state in which the overlap is broken. A guide belt 27 that rotates around a vertical axis that moves the transport speed at substantially the same speed and abuts on the transported crop C on the lateral side of the high-level side of the transport body 21 in the transport width direction. Is arranged over almost the entire area of the transport path, and the inclination lower level side of the exit of the guide chute 25 is inclined toward the lower level side of the carrier 21 toward the lower side of the conveyor. Then, a guide plate 28 made of synthetic resin for changing the posture of the conveyed crop C whose longitudinal direction is the vertical posture along the conveying direction to the horizontal posture is provided. It is mounted so that it can be swung up and down around the axis and the tilt angle can be adjusted. Guide chutes 30 are provided on the left and right sides of the transport body 21 where the transport end portion is located to guide the fallen transported product C onto the reduction belt 29, and the transported crop C guided by the reduction belt 29. Is configured to be returned to the storage hopper 1.

A surface layer material 31 is provided on the mounting surface 21a on the low level side of each carrier 21 and on the working surface of the guide belt 27 so as to resist the slip of the transported crop C and guide it to roll. It is set up. The surface layer material 31 is formed by arranging a plurality of elastic small protrusions on the seat surface like a so-called artificial grass.

In the progressive feeding device 3, the transported crop C is transferred to the transport body 21 on the lower side in the transport direction by the upward movement of the transport body 21 by the crop placing surface 21a in the inclined posture. The transferred crop C is transported by repeating such transfer movement in sequence. At this time, since the transported crop C before being transferred to the transporting body 21 moving downward is received and supported by the front surface of the next transporting body 21, separation is surely performed. Moreover, the width of the carrier 21 along the carrying direction is substantially equal to the width of the transported crop C, and the carrying width in the direction orthogonal to the carrying direction is gradually narrowed. When the above is repeated a plurality of times, the transported crops C that are overlapped by two or more are leveled one by one, and one by one is surely placed near the terminal end.

It should be noted that although reference numerals are added to the claims of the utility model to facilitate comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
