Description

  The present invention lifts a plurality of containers transported by a transport conveyor one by one, pushes up an upper container with a lower container, stacks a predetermined number of stages, and transfers the plurality of stacked containers to the transport conveyor, and The present invention relates to a stacking and unstacking apparatus for containers, in which a predetermined number of stacked containers transported by a transport conveyor are separated from a lower container one by one and delivered to a transport conveyor.

  Conventionally, as a stacking device, a plurality of lifting hooks that push up an article are attached to a rotatable roller chain opposed to each other with a conveyor interposed therebetween, and a holding latch that supports the article pushed up by the hook from a lower side at a predetermined height. The tool can be placed in and out, and after the article is held by the holding latch, the lifting hook can be retracted from the article and returned to the push-up position of the next article, so that the articles can be stacked in series. There is such a stacking device (see Patent Document 1). Further, as the spreader device, a pair of hanger arms that can be engaged with the left and right handles of the bucket and that can be opened and closed in a predetermined direction, an arm lifting cylinder unit that moves the hanger arm up and down, and the hanger arm to a predetermined height position. There is a bucket payout device provided with a roller mechanism that opens a hanger arm at a lowered timing and a roller timing changing means that changes the opening / closing height position of the hanger arm by this roller mechanism (see Patent Document 2).

By the way, since the former stacking device uses the reaction force of the leaf spring for the protrusion of the holding latch, the reaction force is lowered due to the settling of the leaf spring when used for a long time, and the protrusion of the holding latch is I couldn't do it. Further, since the holding latch is retracted when the article contacts the holding latch, the article may be damaged by the holding latch. Furthermore, an impact sound is generated by the return of the holding latch after the article passes, and there is a problem of noise. Further, in the latter leveling device, since the arm lifting cylinder unit for moving the hanger arm up and down is disposed above the stacked containers, the stacking height of the containers is limited within the length of the hanger arm. When the stacked containers are multi-staged, it is necessary to form a long hanger arm and dispose the arm elevating cylinder unit at a high place, resulting in a problem that the apparatus becomes large. Further, since the hanger arm reciprocates up and down, there is also a problem that when the hanger arm descends, the stacking work is interrupted, the speed is low, and the processing capacity is low. In addition, in the conveyance line where both stacking and stacking are required, the stacking device and the stacking device as described above are required, and there is a problem that the cost is high and the installation place is required.
