The control of the box transport facility 1 when the boxed body B in which the need for sealing is mixed is randomly transported is as follows: as shown in FIG. 5, the first method of transporting the entire transport path of the main conveyor 2 is as follows. (Hereinafter, abbreviated as “S1”), the main conveyor 2 is driven by transporting and driving both the start end side 2a, the intermediate portion 2b, the end side 2c, and the lowering position lifting devices 5 and 6, and is packed in a box. When the body B is thrown in and reaches the box alignment portion 7, the box type is determined by the width dimension of the box as well as the alignment of the boxed body B (S1a).

When the box type determination (S1b) is "unsealed", the boxed body B is terminated as it is from the intermediate portion 2b of the main conveyor 2 by both the elevating devices 5 and 6 in the descending position through the terminal side 2c. It is transported to the shipping section (S1c to S1f).

When the box type determination (S1b) is "sealing", when the boxed body B reaches the first elevating device 5 (S2a, S2b), the stopper 5d is raised (S2c) and the boxed body B becomes the first. (1) Positioned on the elevating device 5, and subsequently ascending (S2d) of the first elevating device 5 and the second elevating device 6 causes the boxed body B to project the rear end portion from the conveyor portion 5b of the first elevating device 5 and stand alone. As it rises to the three positions of the diversion conveyor, the hanging stopper plates 5a and 6a prevent the subsequent boxed body B from entering.

When the boxed body B sealed through the operation of the boxing machine 4 (S3a) is conveyed from the divergence conveyor 3 to the second elevating device 6 (S3b), its drive is stopped (S3c) and the boxed body B is held. Then, the lowering (S4a) of the first elevating device 5 and the second elevating device 6 and the respective transfer drives (S4b) return to the full transfer of the transfer path of the main conveyor 2 to transport the boxed body B. It will be resumed and random transport will continue.

(Right angle turn transport)
Next, the right-angled turn transport portion applied to the classification and sorting portion of the boxed body B is positioned and stopped by the movable stopper 12 provided in the transport path 11 as shown in FIG. A horizontal pushing device 13 for changing the direction of B is provided, and a pushing plate 13a for laterally pushing the front end side of the boxed body B is formed as an R shape so that the boxed body B can be moved forward and backward across the transport path by the cylinder 13b. A guide plate 14a is provided at an internal angle position of the receiving right-angled transport path 14.

Since the R-shaped push plate 13a changes the direction of the box-packed body B in a right-angled direction while pushing the side surface of the box-packed body B sideways along the arc surface, the R-shaped push plate 13a has a simple structure. The boxed body B can be efficiently rotated by the lateral pushing device 13 and sent out to the right-angled transport path 14.

Therefore, in the case of side pushing of the boxed body B by the conventional right-angled pushing rod, the right-angled turn transport portion can be configured without requiring an oblique guide roller for compensating for the insufficient rotation of the boxed body B. ..

(Transport opening / closing part)
As shown in FIG. 7, the opening / closing portion of the roller conveyor has a lever 24 for urging the brake plate 23 upward so as to contact the free roller 22 ... Of the portion adjacent to the opening / closing portion 21 from below to suppress rotation. When the opening / closing portion 21 is returned to the closed position, it acts on the lever 24 to release the contact of the brake plate 23, thereby preventing the transported object from falling when the opening / closing portion 21 is opened. be able to.

Further, as shown in FIG. 8 which is a side view of the main part of the drive control, the advance / retreat drive member 24a such as a solenoid or an air cylinder is operated by the open detection switch provided in the receiving part of the opening / closing part 21 to move the brake plate 23 to the braking position. By ascending to, it is possible to prevent the transported object from falling when the opening / closing portion 21 is opened, as described above.

Further, when there are a plurality of opening / closing portions 21, an opening detection switch is provided for each of the opening / closing portions 21, and all the free rollers 22 ... Are simultaneously fixed by opening the opening / closing portion 21 at one of the opening / closing portions 21 to stably hold the transported object. It will be possible.
