It is arranged to be able to reciprocate along the transport direction and the counter-transport direction.
The sub-conveyor 4 is arranged below the main conveyor 3 such that the conveying direction is perpendicular to the conveying direction of the main conveyor 3.

The range in which the main conveyor 3 reciprocates is such that the transport downstream end 31 of the main conveyor 3 is close to the main box packing unit 5 and boxes the farm products in the box 51 placed in the main box packing unit 5 (put in) ) Between the state (hereinafter referred to as a boxed state; see FIG. 2) and the state close to the sub-conveyor 4 and the state where the crop is transferred to the sub-conveyor 4 (hereinafter referred to as the transfer state; see FIG. 3). .
The sub-conveyor 4 can be switched between forward and reverse in the transport direction, and is placed in the sub-box packing unit 6B and the box 61 mounted in the sub-box packing unit 6A along with the switching of the transport direction. The box 62 is switched to a state in which the crop is boxed (inserted).

As an example of proper use of the boxing unit 5 and the boxing units 6A and 6B, for example, the boxing unit 5 can be used according to the size (internal capacity) of the box. Then, a box that can be packed with 10 kg of crop is placed in the sub-boxing unit 6A, and a box that can be packed with 5 kg of crop is placed in the sub-boxing unit 6B.
That is, at the time of boxing of agricultural products, the main conveyor 3 is switched between a boxed state and a transfer state according to a box of a target size, and the transport direction of the sub-conveyor 4 in the transfer state is reversed according to the box of the target size. Switch and box.

The main box filling unit 5 of this embodiment is provided with a flat mounting surface 52 on which the box 51 is mounted, and a weighing device (not shown) that constantly measures the weight of the box 51 on the mounting surface 52. When the weighing device measures the weight of the box 51 and measures the weight for which the measurement result is set, the transfer operation of the main conveyor 3 is temporarily stopped, and the transfer operation is performed when the measurement result is less than the set weight. Is controlled to resume or continue.

In this embodiment, a transfer conveyor 53 for transferring the empty box 51 to the mounting surface 52 is disposed on one end side (upward in the drawing) of the mounting surface 52 and the other end side (lower in the drawing). In addition, a transport conveyor 54 for transporting a box 51 packed with a certain amount of agricultural products is disposed.
The transfer conveyor 53 is controlled by the weighing device so that the transfer operation is stopped when the main conveyor 3 is performing a transfer operation, and the transfer operation is performed when the transfer operation of the main conveyor 3 is stopped. .
A large number of empty boxes 51 are arranged on the transfer conveyor 53 along the transfer direction, and the box 51 on the most downstream side in the transfer direction is transferred to the mounting surface 52 by the transfer operation of the transfer conveyor 53. At the same time, the box 51 to be transferred transfers the box 51 packed with agricultural products placed on the placement surface 52 so as to push it onto the conveyor 54.
The transport conveyor 54 is always transported regardless of the control by the weighing device, and transports the boxes 51 packed with the crops transferred as described above.

That is, when the agricultural product conveyed by the main conveyor 3 is put into the box 51 mounted on the mounting surface 52 and the weight of the box 51 is measured to be the set weight, the conveying operation of the main conveyor 3 is performed. Is stopped, the transfer conveyor 53 is transported to transfer the empty box 51 to the placement surface 52, and the box 51 packed with agricultural products is transferred to the transport conveyor 54.

The main conveyor 3 can be switched from the boxed state to the transfer state either manually or automatically. For example, when the number of boxes in the main box packing unit 5 reaches a predetermined number, a switch or the like (not shown) is manually operated. Then, the main conveyor 3 is moved in the counter-conveying direction, and the conveying direction of the sub-conveyor 4 is moved in either the forward or reverse direction, so that the sub-conveyor 4 is placed on the sub-box packing unit 6A or the sub-box packing unit 6B. The box 61 or the box 62 is switched to the boxed state.
In the case of automatic, the number of boxes packed in the main box packing unit 5 is counted, and when the number reaches the predetermined number, the main conveyor 3 is moved in the counter-conveying direction and the conveying direction of the sub-conveyor 4 is corrected. Control is performed so that the sub-conveyor 4 is switched to a boxed state with respect to the box 61 or the box 62 placed on the sub-box packing unit 6A or the sub-box packing unit 6B by operating in either direction.
Examples of the drive structure for reciprocating the main conveyor 3 include known drive structures such as a cylinder drive that expands and contracts by fluid or gas, and a chain or belt drive that rotates forward and backward.
The automatic switching control is not limited to the exemplified control, and various controls can be performed by arbitrarily setting the control.

The auxiliary boxing units 6A and 6B also have a mounting surface 63 similar to the mounting surface 51, a weighing device (not shown) similar to the weighing device provided in the main box packing unit 5, and a transfer conveyor 53. Similar to the transport conveyor 54, a transfer conveyor 64 and a transport conveyor 65, which are controlled by the weighing device, are provided.
