Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for stacking uneven thickness articles in one stack.

For example, it is a package in which granular materials, viscous materials, other foods, medicines, etc. are packaged in a packaging bag in a fixed quantity, and one long side IA and both end sides IB and IB are sealed and packaged as shown in Fig. 1. 1 (
Hereinafter, products having such a shape will be collectively referred to as uneven-walled products.

In the case of the above-mentioned articles with uneven thickness, as shown in the cross section in Fig. 2, the long side IC on the unsealed side bulges out to the side edge, so it is difficult to stack a large number of them in a stacked state. When tying them together, a good stacking condition cannot be obtained unless the bulging sides are alternated and overlapped, resulting in wasted space inside the container and a reduction in the number of items that can be stored.

For this reason, when conventional casers are used to pack uneven-thickness articles as described above, they tend to collapse when piled up, making it difficult to pack them in an aligned state. Each one is turned alternately to cover the rain.
This resulted in extremely inefficient work.

In view of this, the present invention has been made for the purpose of providing a caser that can stack unevenly-thickness articles in an orderly manner by stacking them in an aligned manner. In the supply route that supplies uneven thickness products to the location,
A reversing mechanism is provided for reversing every other uneven-thickness article, and the uneven-thickness articles that have been reversed by the reversing mechanism and the uneven-thickness articles that have not been reversed are alternately stacked in a stacking section.

It has a width that allows it to pass between the spaces 28B and a length that is close to the bottom 28A, and is formed in a shape that allows stacked articles to be pushed into the space 41 from above the pedestal u. In the figure, 42 is a push-back cylinder for transferring the A-sket path onto the back conveyor 33.

Next, the operation of the above embodiment will be explained.

The uneven thickness article 1 supplied to the upstream side of the conveyance path 6 is slid and conveyed due to the inclination of the conveyance path 6.

At this time, the cross section of the reversing member 70 through hole lO is the conveyance path 6.
The stop plate 19 on the downstream side is opened, and when one article enters the through hole 10, the stop plate 19 on the upstream side is closed and the next article is placed in the same plane as the through hole 10. Do not enter the hole 10.

The articles passing through the through-hole 10 enter the storage chamber 21 from the end of the conveyance path 6 and are deposited on the lower storage plate M projecting into the storage chamber 21.

On the other hand, when the article enters the storage chamber 21, the downstream stop Iida is closed, and the upstream stop plate 1
9 is opened and the next article is stored inside the reversing member 7,
Then, the air cylinder 16 is actuated and the sector gear 15. Binion 14. The reversing member 7 is rotated 180' through the gear 13.

After the reversal, the stop plate on the downstream side opens, and the reversible article slides from inside the reversing member 7 and is stacked on top of the article on the storage plate 21.

When the above action is repeated every other time and a predetermined number of uneven thickness articles are stacked on the storage plate U, the upper storage plate n protrudes due to a signal from a counting mechanism, for example, and the lower storage plate The board is moved back and the articles stacked on it are squeezed down into the Nonosket path, and the stacked items are transferred again.

Note that the articles to be continuously conveyed are once stacked on the upper storage plate n in the same manner as described above.

When the articles have been transferred into the Nonosket row, the holding member 4 is pulled up to open the outlet 3A, and the air cylinder γ is operated to push the Nonosket 4 onto the forward conveyor 32. When the presser member 4 is lowered, the pressing plate 31 presses the stacked articles in the basket 28 so that the articles are stacked without any gaps, and then sent to the downstream side and placed in the basket receiver of the placement section 4. It is placed on a table.

When the pass scaler) 28 is placed on the predetermined position f on the Nono Sket holder A, the push plate 35 moves to the right in FIG. Push it inside 41 and finish the fight.

After one article has been stuffed, when the push plate returns to its original position, the drive mechanism 36 of the pedestal 34 is driven and the Nonosket pedestal 34 is lowered to the same level as the rear conveyor 33, and the push-back cylinder 42, the basket A is transferred onto the back conveyor 33 and descends to be returned to the stacking section 3.
2, and the stacked articles which had been transferred from the upper storage plate B to the lower storage plate U using the roof tile are received into the slot 28 by the same action as described above.

It should be noted that the drive means for the above-mentioned parts in the present invention are not limited to the illustrated embodiments, and can of course be modified in design as appropriate.

As explained above, according to the heavy-viscosity method according to the present invention, there is a through-hole capable of enclosing one uneven-thickness article in the middle of the conveyance path for conveying the uneven-thickness article. A reversing mechanism equipped with a reversing member that is driven to reverse is provided, and the reversing mechanism intermittently transports uneven thickness articles by turning them upside down every other time and supplying them to the stacking section. Since the thick side and the thin side are stacked in a state where they are alternately in contact with each other and then supplied to the eyelid resting section for image packing, even if the object to be handled has uneven thickness, it will be in an orderly and stable state. There are various effects such as the fact that even if there are a predetermined number of bins stacked in a small volume, the stacked state will not be disturbed inside.

Furthermore, according to the molding device of the present invention, since the uneven-thickness article is reversed by the rotating operation of the reversing member interposed in the middle of the conveyance path, the uneven-thickness article can be difficult to handle with the addition of a simple configuration. It can be reliably reversed even if
Furthermore, since the stacked state is maintained by the Nono Sket, it will not collapse until the drawing is finished, and in the storage chamber, the storage plates that appear and reappear alternately temporarily store the items, so it is possible to continuously supply the items. This can greatly improve work efficiency.
