However, in order to avoid the complication of the drawings and clarify the operations of the delivery device 12 and the stacking and transporting device 13, the width of the transport surface of the stacking and transporting device 13. The description of the buckets 44 and 45 is simplified by neglecting the inclination of the direction. Further, in order to clearly show the operation of the delivery table 24, a unique reference numeral is appropriately attached to each delivery table 24 and each article X.

First, as shown in FIG. 12, for example, predetermined 12 articles X _{1 to} X ₁₂ are already held in a standing posture in the preceding bucket 44 in the stacking and conveying apparatus 13, and the bucket 44 almost reaches the discharge position P2. In addition, five articles X _{1 to} X ₅ are held in a standing posture in the subsequent bucket 45. Transfer table 24 ₁ preceding the delivery device 12 from behind the article X ₅ tail end is attempting to retreat rearward upward rotated in the arrow d direction. In the receiving position P1, a new article X ₆ in the transfer table 24 ₂ the subsequent is supplied. The remaining delivery tables 24 ₃ and 24 ₄ are in the positional relationship shown in the figure. Then, the air cylinder 72 of the upper guide mechanism 71 moves the presser member 73 upward so that it is retracted to a position that does not hinder delivery of the article X.

Next, as shown in FIG. 13, the articles X _{1 to} X ₁₂ held in the bucket 44 are discharged all at once by the drive of the pusher device 81 of the discharge device 14 that moves in synchronization with the buckets 44 and 45. The bucket 44 discharged toward the guide device 91 and emptied retreats from the discharge position P2 as indicated by an arrow b, and moves to attach to the upstream side of the succeeding bucket 45.

On the other hand, in the receiving position P1 near to the landing transfer table 24 ₂ holding an article X ₆ are close to the bucket 45 while rotating in the arrow d direction, the lower end portion of the article X ₆ in the lower guide member 62 while, gather the article _{X 6} in the article _X 1 to X ₅ direction which is held in the bucket 45. At this time, the transfer table 24 _2, which is shaped to not interfere with each other as described above and the lower guide member 62 intersect.

Then, as shown in FIG. 14, the bucket 45 while moving in the arrow b direction by one minute article transfer table 24 ₂ is being passed articles X ₆ in the bucket 45 is further rotated in the arrow d direction standing with the posture, gather the article _{X 6} in an upright position behind the article _X 1 to X ₅ in the bucket 45. On the other hand, transfer table 24 ₃ subsequent is close to the receiving position P1, and is about to become a predetermined receiving position.

In this case, as shown in FIGS. 5 and 6, the conveyance surface of the bucket 45 is inclined in the width direction by an angle γ, so that the article X ₆ delivered to the bucket 45 is on the lower side due to the inclination. The movement is restricted by the side guide member 61 located on the side.

Further, as shown in FIG. 1, since the conveyance surface of the bucket 45 is inclined downward by an angle β toward the downstream side, the article X ₆ delivered to the bucket 45 is inclined forward from the inclination. It is held in stuff.

Further, the pressing member 73 by the operation of the air cylinder 72 of the upper guide mechanism 71 moves downward as indicated by arrow e, hold the upper portion of the article X _5, etc. of the article X ₆ or the vicinity.

The empty bucket 44 overlaps within a predetermined range on the upstream side of the bucket 45 that is receiving the article, and the predetermined 12 pieces of X ₁ are separated by the partition members 51 and 51 of the buckets 44 and 45. space for holding to X ₁₂ are defined. After the overlap, both buckets 44 and 45 move in synchronization.

Then, as shown in FIG. 15, is on the bucket 45 in the article receiving and six articles X ₁ to X ₆ is held in a standing position, the transfer table 24 ₂ having been subjected to transfer the times in the direction of arrow d and moving, it is being retracted from behind the article X ₆ rearmost rearwardly upwardly. In that case, by the operation of the air cylinder 72 of the upper guide mechanism 71, the pressing member 73 is pressed down an upper end of such article X ₆ is moved upward as indicated by an arrow e '. Then, the transfer table 24 ₃ which follows, which is a predetermined receiving position at the receiving position P1, and a new article X ₇ is supplied.

As described above, the delivery device 12 is provided with the _four delivery tables 24 _{1 to} 24 _4, which are replaced and can receive the article X from the upstream side, thereby speeding up the accumulation process at the delivery position P 1. .

Then, as shown in FIG. 16, when the _twelfth article X12 is delivered to the bucket 45 by the delivery table 24, when the bucket 45 moves toward the discharge position P2 as indicated by the arrow b, a transfer table 24 to be retracted to pivot serves as the partition member 51 of the subsequent bucket 44 in the arrow d direction of the end holding member from behind of the article X ₁₂ is to be crossed. That is, as shown in FIG. 6, since the standing portion 51 a of the partition member 51 and the placement surface 24 a of the delivery table 24 are formed in a comb-teeth shape, the partition member 51 of the bucket 44 has the delivery table interchanged intersects the 24 holding the article X ₁₂ of the rearmost end.

  With the above configuration, the conveying surface of the conveying means, that is, the conveying surface formed by the buckets 44 and 45 connected to the flat belts 43 and 43 is inclined in the width direction. The article X that has been transferred to the buckets 44 and 45 that are transferred in the upright position via the delivery device 12 is moved to a lower side due to the inclination, and the side portion of the article X contacts the side guide member 61. As a result, the positions of the side portions of the article X are aligned on the buckets 44 and 45. That is, the articles X can be stably conveyed without disturbing the arrangement of the articles X, and the subsequent discharge process can be performed smoothly.

  Incidentally, the buckets 44 and 45 are usually provided with a front end holding member and a rear end holding member for holding the accumulated articles X... X from the front and rear. Since the conveyance surface, that is, the conveyance surface formed by the buckets 44 and 45 connected to the flat belts 43 and 43 is inclined downward toward the downstream side, the article X held in the standing posture on the buckets 44 and 45 is inclined forward. The front is held by a partition member 51 as a front end holding member, and the rear end holding member can be omitted.

  It should be noted that the present invention is not limited to the above-described embodiment that has been specifically described in detail, and may be any that are within the spirit of the present invention. For example, the inclination angles α, β, and γ are not shown by using specific numbers, but are set in a range in which the article X is stably conveyed and delivered. In particular, the angle α may be zero.

  The stacking and conveying device 13 is provided with a pair of flat belts 43 and 43 and buckets 44 and 45, which can be added respectively.
