In this case, when the fresh leaves T are sampled, the belt conveyor 13 is moved in the direction of the arrow, and its one end side 13a is positioned below the downstream side 12b of the belt conveyor 12, and when the fresh leaves T are returned to the container 2, the belt conveyor 13 is moved in the direction of the arrow e, and the one end side 13 a is positioned on the container 2.
[0021]
Three sampling conveyors 3 are arranged at predetermined positions by arranging the three conveying conveyors 10 including the two belt conveyors 12 and 13 in parallel in the conveying direction of the container 2 at predetermined intervals. The storage box 11 of each sampling device 3 is placed on the floor surface 9 below the other end side 13b of the belt conveyor 13, and is formed in a rectangular shape in plan view. For example, fresh leaves T are accommodated in 1 to 2 kilograms. It is set to the size to get.
[0022]
Next, the operation of the sampling device 3 will be described. First, as shown in FIG. 2, the truck t loaded with the plucking bags F is stopped at positions corresponding to the sampling devices 3 on the side wall 4 a side of the container 2, and the plucking bags F are put on the loading platform by the loading operator. Take it down and open it. Then, by operating the assessor's operation panel S, the belt conveyor 12 is stopped at a predetermined position, the belt conveyor 13 is actuated, and the timer for the motor 24 is set at a predetermined time, The opening portion of the opened plucking bag F is directed from the side wall 4 a side of the container 2 into the container 2, and the fresh leaves T in the plucking bag F are put into the container 2. This charging operation can be performed simultaneously at, for example, three locations corresponding to the sampling devices 3.
[0023]
When the fresh leaves T are put into the container 2, a part of the fresh leaves T in the plucking bag F is placed on the flat belt 15 on the upstream side 12 a of the belt conveyor 12 and collected. At this time, the fresh leaves T are collected in a piled state in the partition portion K located on the most upstream side of the flat belt 15, that is, in a state where both sides parallel to the conveying direction B in the partition portion K are low and the central portion is high. As a result, a certain amount of fresh leaves T in the first plucking bag F is collected according to the size of the partition portion K.
[0024]
When the introduction of the fresh leaves T of the first plucking bag F is completed, the assessor operates the operation panel S to rotate the motor 18 of the belt conveyor 12 by one step, and the flat belt 15 of the belt conveyor 12 is moved by one step. Move. Thereby, the fresh leaves T collected in the partition part K are conveyed by a predetermined distance in the downstream 12b direction. Thereafter, when the fresh leaves T of the second plucking bag F are introduced, a certain amount of the fresh leaves T are similarly collected in the next partition K, and this is repeated, whereby the raw leaves T of the consignment made up of a plurality of plucking bags F are collected. However, each plucking bag F is collected on the belt conveyor 12.
[0025]
The fresh leaves T collected on the belt conveyor 12 are conveyed stepwise to the downstream side 12b, fall downward from the edge of the downstream side 12b, and are accommodated in a substantially central portion on the flat belt 21 of the belt conveyor 13. Is done. The fresh leaves T are conveyed to the other end side 13b of the belt conveyor 13 by the flat belt 21 rotating in the normal rotation direction (arrow C direction), and dropped and accommodated in the storage box 11 from the edge of the other end side 13b. The
[0026]
When a predetermined time has elapsed from the start of the belt conveyor 13, the motor 24 is reversed by the timer of the operation panel S, and the belt conveyor 13 rotates in the reverse direction (arrow D direction). As a result, the fresh leaves T conveyed by the belt conveyor 12 are conveyed by the belt conveyor 13 in the direction of the one end side 13a and returned into the container 2, so that the fresh leaves T are not dropped into the storage box 11, and the storage box A predetermined amount of fresh leaves T is accommodated in 11 and sampled.
[0027]
In this state, the storage box 11 is taken out from below the belt conveyor 12 and the quality of the sampled fresh leaves T is checked. The belt conveyors 12 and 13 operate until the loading of the raw leaves T at the loading port is completed, and the raw leaves T collected by the belt conveyor 12 at the time of loading are returned into the container 2 via the belt conveyor 13. . When the fresh leaves T are rated by the quality check, the assessor returns the storage box 11 to the original position, and similarly performs the quality check of the fresh leaves T in the storage box 11 of the next sampling device 3.
[0028]
Then, the raw leaves T that are sequentially put into the container 2 from the plucking bag F by the loading operator and accumulated at a predetermined height are transported in the direction of the scraping device 8 by the transport conveyor 5 that is appropriately rotated. During this time, the fresh leaves T in the container 2 are temporarily stored while being humidified and blown by the blowing humidifier 6. In addition, the fresh leaves T conveyed to the position of the scraping device 8 are dropped into the vibrating conveyor 26 (see FIG. 1) by the scraping device 8 that rotates as necessary, and the vertical conveyor 27 or other appropriate transport machine. For example, it is supplied to the next container (not shown) which comprises a fresh leaf management apparatus.
[0029]
In this embodiment, as shown in FIG. 3, for example, only the belt conveyor 12 is used as the transfer conveyor 10, and the storage box 11 is directly placed on the floor surface 9 below the downstream side 12b of the belt conveyor 12. It may be arranged. In this case, when a predetermined amount of fresh leaves T are stored in the storage box 11 and sampled, the storage box 11 is removed from the lower side of the belt conveyor 12, and the inclined table 28 is disposed at the removed position. Due to the inclined surface of the inclined table 28, the fresh leaves T conveyed by the belt conveyor 12 are returned into the container 2.
[0030]
Thus, according to the above embodiment, if the fresh leaves T are put into the container 2 at a position corresponding to each sampling device 3 on the side wall 4a side along the conveyance direction of the container 2, the flatness of the belt conveyor 12 is obtained. The fresh leaves T are automatically collected in the section K formed on the belt 15 and are transported by the belt conveyors 12 and 13 and stored in the storage box 11, so that it is not necessary to sample the fresh leaves T by the assessor. Become. As a result, it is possible to eliminate the involvement of human factors in sampling, and it is possible to accurately check the quality of fresh leaves T at the consignment.
[0031]
In particular, the partition K provided on the belt conveyor 12 enables uniform collection of fresh leaves T from a plurality of plucking bags F, prevents sampling from the biased plucking bags F, and allows the storage box 11 to The installation position and the position of the raw leaf T loading operation are clearly separated with the container 2 sandwiched therebetween, and the importer (the position of the truck t) and the sampling device 3 can be made to correspond one-to-one. In addition, the operation panel S for operating the belt conveyors 12 and 13 is provided on the storage box 11 side which is the anti-loading work side, so that the operation by the loading worker is prevented. This enables more accurate and fair sampling of the fresh leaves T.
[0032]
In addition, since the three sampling devices 3 are arranged side by side in the transport direction of the container 2 from the side wall 4a side of the container 2 to the side wall 4b side, the raw leaves T carried in by the three trucks t are The containers 2 can be simultaneously loaded, and the work efficiency of the carry-in work can be improved. As a result, stagnation at the place where the fresh leaves T are carried in is surely prevented even at the peak time when plucking overlaps. Furthermore, since the upper surface 12a of the upstream side 12a of the belt conveyor 12 is set to be flush with the floor surface 9, it is not necessary to lift the heavy plucking bag F that has been lowered from the loading platform of the truck t during the loading operation. Work can be done easily and easily.
[0033]
In addition, the conveyor 10 can return the fresh leaves T conveyed by the belt conveyor 12 to the container 2 by reversing the motor 24 of the belt conveyor 13 or by arranging the tilting table 28, and storing it. After the box 11 is removed, scattering of the fresh leaves T to the floor surface 9 is reliably prevented. Furthermore, the sampling device 3 only needs to be installed in a state where the transport conveyor 10 is spanned between the both side walls 4a and 4b of the machine frame 4 of the container 2, and the existing container 2 can be easily modified without major modification. The sampling apparatus 3 can be constructed at low cost by simplifying the configuration, such as using belt conveyors 12 and 13 that are commercially available as the conveyor 10.
[0034]
4 and 5 show another embodiment of the sampling apparatus according to the present invention. FIG. 4 is a plan view of the main part thereof, and FIG. 5 is a cross-sectional view taken along line BB in FIG. In addition, the same code | symbol is attached | subjected to the same location as the said Example, and the detailed description is abbreviate | omitted. The feature of this embodiment is that the conveying conveyor 10 of the sampling device 3 is constituted by a single belt conveyor 12, and this belt conveyor 12 is arranged so as to be movable in the conveying direction of the container 2.

The rail 32 is fixed to the upper end of the inner surface of the side wall 4a.
[0035]
Then, the conveyor 10 lifts the downstream side 12b together with the bracket 31 in the direction of the arrow with the rail member 30 of the belt conveyor 12 fitted in the rail 32 of the container 2 as shown in FIG. The conveyor 12 is slid in the longitudinal direction of the rail 32, and the bracket 31 is placed on the floor surface 9. As a result, the belt conveyor 12 moves a predetermined distance in the transport direction of the container 2 as shown by a two-dot chain line in FIG.
[0036]
In this embodiment, the case where one transport conveyor 10 is disposed has been described. However, a plurality of transport conveyors 10 may be movably disposed, and rails (see FIG. (Not shown), the lower end of the bracket 31 may be fitted into the rail, and the belt conveyor 12 may be moved without being lifted. Also, a roller (not shown) that can be rotated by a motor is attached to the upstream side 12a of the belt conveyor 12 and the lower end of the bracket 31, and the belt conveyor 12 is automatically moved by rotating the roller in the rail. Of course, it is possible to use two belt conveyors 12 and 13 as the transfer conveyor 10 as in the above embodiment.
[0037]
According to this embodiment, in addition to the operational effects of the above embodiment, the transport conveyor 10 of the sampling device 3 can be adjusted to the input position of the fresh leaves T (stop position of the track t) and stored in the container 2. Since the loading position can be changed according to the storage state of the raw leaves T that are being carried out, the carrying-in operation can be performed more efficiently and the storage height of the raw leaves T in the container 2 can be made uniform. The effect is obtained.
[0038]
Also, in the above embodiment, the leaf T taken by the partition portion K of the belt conveyor 12, and stored in the collecting box 11, the leaf T of the collecting box 11 has been adapted to the quality check, for example, The assessor may collect an appropriate amount of the fresh leaves T in the respective sections K conveyed by the belt conveyor 12 in a step shape on the downstream side 12b of the belt conveyor 12, and the quality check may be performed using the fresh leaves.
[0039]
