Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of stacking articles A having a unique shape, such as that shown in FIG. 14, at a slight angle so that adjacent articles A partially overlap each other.

As shown in Fig. 14, it is a package that stores food, youth, etc., and is called a stand pouch.The bottom side a is approximately cylindrical or oval, and the top side a' is flat so that it can be stood up on a tabletop, etc. However, when storing and packaging multiple items in one box, as shown in Figure 15, several items A may be slightly tilted and placed next to each other in order to improve packaging efficiency. It is a good idea to have the two parts partially overlap. Also, the flat part of this article A
Packaging efficiency is further improved by arranging and packaging a' in two rows, one on top of the other, in one box.

The present invention is extremely convenient when used to automatically and efficiently tilt articles with extremely unique shapes and stack them so that adjacent items partially overlap. The reason for this is that the articles placed one by one on the article conveying bucket of bucket conveyor C should be accumulated at the center line c ₂ on the side of the bucket with respect to the center line c ₁ of the bucket. A side plate that is pushed out one by one into a baggage bucket that is aligned and shifted in either the front or rear direction within an area smaller than the width of the item, and a part of the item is tilted with respect to the bottom plate. By placing the articles on top of each other, the articles are tilted in the cross-bucket, and then the distance between the front and back of the cross-bucket is narrowed, and each of the gathered articles is taken out laterally from the cross-bucket to separate the adjacent items. It lies in the fact that parts overlap each other.

Embodiments of the present invention will be described based on the drawings. Figures 1 to 9 of the drawings show an example of an apparatus suitable for carrying out the method of the invention.

In the embodiment, a case is illustrated in which five articles A are stacked into one set.

As shown in FIG. 1, a large number of buckets 2 are mounted on a chain 1 at regular intervals in the front and back. This bucket conveyor C has 25 buckets each, that is, 5 buckets.
It is assumed that the buckets 2 are driven intermittently one by one, and each bucket 2 has a substantially gutter-like shape when viewed from the side, with no walls on either side.

At the front end of the bucket conveyor C, a receiving plate 3 is provided horizontally inside the five buckets 2, and further inside the receiving plate 3, a bucket 4 for width adjustment is arranged between the pitches of the buckets 2 for transporting goods. Five buckets are installed at equal intervals in the front and back so that the buckets match, and the four buckets 4 other than the first bucket 4a are slidable in the front and back direction along the rods 5 arranged in the front and rear direction, so that the distance between the front and rear buckets is Make it possible to make them relatively different. To do this, as shown in FIG. The base 6 (at the right end in Figure 4) is fixed to the cylinder head 9a of the cylinder 9 arranged in the front-rear direction. cylinder 9
When the piston rod protrudes as shown in FIG. 6, the four bases 6 slide on the rod 5, the distance from the first base 6a decreases, and the distance between the buckets 4 and 4a for width adjustment becomes relatively large. It will become narrower.

In addition, in FIGS. 4 to 6, reference numeral 10 is a guide rod for guiding provided directly below the rod 5, and the base 6
A pair of left and right rollers 11, 11 provided below the guide rod 10 are arranged to sandwich the guide rod 10 so as to run along the guide rod 10.

As shown in FIG. 3, the bucket cart 4 or 4a for carrying goods has almost the same shape as the bucket cart 2 for transporting goods, and the bucket carts 2 or 4a are for carrying goods on both the left and right sides.
Although it is assumed that there is no wall in the same way as in the case where the buckets 4 or 4a are not close to each other, the center line of the buckets for width
c ₂ is a bucket 2 for transporting goods, as shown in the same figure.
Within a range smaller than the width of the items to be accumulated (indicated by α in the drawing) with respect to the center line c ₁ of
Install it so that it is shifted toward the rear. As shown in FIG. 3, the bucket bag 4 or 4a for carrying the bag is provided with a side plate 42 that is inclined with respect to a horizontal bottom plate 41. In this way, by shifting the positions of the bucket cart 2 for transporting articles and the bucket cart 4 or 4a for pulling, the articles A pushed out from the bucket cart 2 will be placed on the bucket cart 4 or 4a for pulling as will be described later. When transferred, a part of the body rests on the side plate 42 which is inclined with respect to the bottom plate 41, so that the body position is automatically changed by being slightly inclined. In addition,
Bucket 2 for transporting goods and Bucket 4 for shuffling
The bucket carts 4 to 4a may be arranged at the same height as shown in FIG. 3, but as shown in FIG. It is best to place it low. In that case, it would be possible to more smoothly transfer the articles A from the article transport bucket 2 to the gathering bucket 4 or 4a.

Outside the front end of the bucket conveyor C, there are five bucket carts 2 for transporting articles, as shown in FIG.
A pusher 12 is provided which serves to push the articles A placed on the bag at once and push them into a baggage bag 4 or 4a on the side of the pusher 12. The seventh
Pusher 1 performs the movement shown in Figure L and serves to push out the articles A in the bag for gathering after approaching at once.
3 will be provided.

To operate the pusher 13 as shown in FIG.
6, it is better to move the machine frame 17 up and down.

As shown in FIG. 9, the extrusion plate of the pusher 12 is provided with protruding portions 12a having the same shape and fitting into the respective recesses of the five bucket carts 2 for transporting articles.
are arranged in rows, and, like the pusher plate of the pusher 12, the pusher plate of the pusher 13 is also provided with a plunger that can fit into each recess of the bucket 4 or 4a for gathering after approaching. ing.

In the embodiment, there is a bucket conveyor C, and a group of bucket belts 4 for width shifting, which can vary the distance between the front and rear.
Or 4a and pushers 12 and 13 are the first
arranged symmetrically with respect to the center line C ₁ of the figure,
These move in the same way on both the left and right sides. In addition, between the left and right bucket bags for sorting, a large number of bucket bags 14 for accumulation are arranged on the center line _C1 , front and rear, and the articles A accumulated on both the left and right sides are stored in one bag as will be described later. bucket bag 1
4 at the same time.

Next, the accumulation work status will be explained step by step.

Article A with a unique shape as shown in Figure 14
are placed one by one on each bucket 2 of the bucket conveyor C so that the flat part a' is inward, and are sequentially sent forward by the intermittent rotation of the bucket conveyor C. The one in the set is the 10th
As shown in the figure, when the bucket conveyor C is sent to the outside of the receiving plate 3, the bucket conveyor C temporarily stops.

At this moment, the pusher 12 operates up to the chain line in FIG. Push it into the buckets 4a and 4 for wrapping (Fig. 11). In this case, as shown in FIG. 3, the positions of the bucket cart 2 for transporting articles and the bucket cart 4a or 4 for width shifting are shifted by α, so that the articles placed horizontally on the bucket cart 2 When A is transferred to the buckets 4 to 4a as described above, he changes his body position so that both of them are slightly tilted in the same direction, as shown by the chain line in FIG.

As soon as the article A is placed on the baggage cart 4 or 4a in a slightly tilted state, the cylinder 9 is activated and pushes the last base 6 forward, so that the three bases 6 in front of it are pushed forward. All four bases 6 including the one sliding on the rod 5, the distance between the first base 6a and the four bases 6 on the rear side narrowed, and the goods placed on the baggage cart 4 or 4a were removed. In A, the distance between the front and rear becomes narrower, and the pieces are gathered together as shown in FIG. At this time, chain 8 is connected to each base 6.
There is some slack between 6a and 6a.

Cylinder 16 is then actuated. Then,
The pusher 13 is lowered to the position shown by the chain line in FIG. 7, and is positioned outside the set of five buckets 4 to 4a with narrowed front and rear spacing.

At this moment, the cylinder 15 is actuated, and the pusher 13, which was in the position indicated by the chain line in FIG. 7, is actuated horizontally inward. Therefore, the article A in the baggage bag 4 or 4a whose front and rear spacing is narrowed is
As shown in FIG. 13, it is pushed out from each of the bucket carts 4 to 4a and pushed into one bucket cart 14 waiting inside thereof. In this case, the article A that was placed on the baggage bag 4 or 4a
Since they are all tilted somewhat in the same direction, the articles A pushed out from here are stored in the bucket 14 while being slightly tilted so that the adjacent ones partially overlap.

In the example, this work is performed on both the left and right sides of the center line _C1 , so a set of 5 items A, each of which is adjacent to the other and partially overlapped, is placed in one bucket truck from both the left and right sides. 14, and their flat portions a' are placed one on top of the other as shown in FIG. Therefore, one set of five articles A
are arranged in two rows on the left and right in one bucket 14, greatly improving the accumulation efficiency. Then, the bucket 14 is sent forward (to the left in FIG. 1) and when it reaches the article filling position (not shown), the articles A in the bucket 14 are stored in one box B as is.

Thus, as shown in FIG. 15, a total of 10 articles A are placed in one with the adjacent items partially overlapping and the flat parts a' overlapping each other.
It can be stored neatly in one box B.

Note that when pushing articles into the bucket 14 using the two left and right pushers 13, 13, if the guide plate 18 for guiding the articles is inserted diagonally into the middle of the bucket 14 as shown in FIG. The part (the flat one) of the group (the one on the right in FIG. 8) is guided by the guide plate 18 and rises above it, ensuring that it is guided over the other group of articles.

In the embodiment, a case has been described in which the article A is tilted so that the front side of the article is higher.
If the position of 4a is shifted forward by α,
The article A can be tilted so that the rear side of the article is higher, and the present invention can also be applied in this case.

According to the method of the present invention, the body position of a plurality of articles being conveyed at predetermined intervals is automatically changed so that the front side or the rear side in the conveying direction is higher, and the body position is automatically changed so that some of the articles overlap each other. It has the effect of being able to be accumulated over time.
