The guide adjusting means 3 is connected to the guide control means 4 for adjusting the position of the guide portion, and the guide control means 4 is connected to the width detecting means 2 described above.

Further, as shown in FIG. 3, the surface of the guide portion 5 on the cardboard box 9 side is moved and adjusted to a position with a little margin with respect to the cardboard box 9.

Next, the operation of the above embodiment will be described with reference to FIG.

First, a certain number of toner-filled cartridges (for example, M type) are packed in a corrugated cardboard box 9M in the previous step and are conveyed by an upstream conveyor 10. At this time, regardless of the size of the cardboard box 9, one side of the cardboard box 9 is the conveyor 1
With reference to the side of the guide frame 5 having no guide portion 5, that is, the frame 14 on the upper side in the drawing, it is assumed that the frame is placed straight in the transport direction and transported.

Next, when the corrugated board box 9M is conveyed to the lower side of the width detection means 2, the width detection means 2 has the width of the corrugated board box 9M (here, since the corrugated board box 9 is placed straight in the conveying direction). , Size in the direction orthogonal to the transport direction)
To detect. The detected width is input to the guide control means 4, and the guide control means 4 rotates the motor 31 according to the detected width, and the motor 31 drives the drive unit 30 to set the rod 32 to a predetermined size. Move to the position. As a result, the guide portion 5 connected to the rod 32 moves, and the conveyance width of the conveyor is adjusted to match the size of the cardboard box 9M. After that, when the corrugated cardboard box 9M is conveyed from the upstream conveyor 10 and delivered to the downstream conveyor 10, even if the corrugated cardboard box 9M tries to rotate due to a step, the guide portion 5 blocks this. In order to arrange the orientation, the cardboard box 9M is conveyed straight on the downstream conveyor 10 as shown in FIG. 3 (the conveying direction is the upper side in the drawing as indicated by the arrow).

Next, a cartridge of another size filled with toner (for example, this is an L type) is packed in a corrugated cardboard box 9L in a previous step, and is conveyed by the upstream conveyor 10. It will be transported. Also in this case, the corrugated cardboard box 9L has one surface of which is the guide portion 5 of the conveyor 10.
