The above-described conventional article aligning / conveying apparatus requires a large number of constituent parts, uses a specially shaped screw, and is a roller for correcting a conveying posture that rotates in a horizontal plane. There are various problems such as a large space is required because the direction is corrected by.

The present invention has been made to eliminate the above-mentioned problems, and it is possible to correct the direction of an article with a simple structure and in a small space, and the direction is corrected so that a fixed direction is maintained. An object of the present invention is to provide a device for correcting the direction of an article, which can guide and hold the posture of the container so that the container that has faced does not change its direction again.

[0006]

An article direction correcting device according to the present invention is a conveyor for conveying articles having different vertical and horizontal widths, and a first conveyor having a conveyance surface having a width substantially equal to the horizontal width of the article, A conveyor guide is provided on the first conveyor to guide the side surface of the article to be conveyed, and a second conveyor is provided in parallel with the first conveyor. The traveling speed of the second conveyor is set to the first
The second conveyor is different from the first conveyor, and the height of the second conveyor is gradually increased from the same height as the first conveyor.

[0007]

In the above-described article direction correcting device, an article conveyed with its longitudinal direction oriented forward and backward is placed on the first conveyor and advances as it is, and an article whose longitudinal direction is oriented laterally straddles both conveyors. And is rotated by the difference in speed between the two conveyors and the ascending movement of the second conveyor, so that the article is corrected in the same direction as the article whose longitudinal direction is directed forward and backward.

[0008]

The present invention will be described below with reference to the illustrated embodiments.
FIG. 1 is a plan view of a device for correcting the direction of an article according to an embodiment of the present invention. It is provided on the downstream side of a collective conveyor (see FIG. 2) that supplies container processing devices such as a sticking device).

The collective conveyor 2 comprises a large number of conveyors 2a, 2b, 2c, 2d, 2e, 2f, 2g arranged in parallel.
2h, 2i, 2j, 2k, 2m and these conveyors 2
A motor (not shown) for driving a to 2 m and a guide member 4 obliquely arranged from the inlet side A to the outlet side B of the collective conveyor 2 are provided.
a to 2 m are driven to run so that the traveling speed gradually increases from the inlet side A to the outlet side B (from the upper side to the lower side in FIG. 2), and the containers 6 conveyed in a plurality of rows from the inlet side A.
Are conveyed by the conveyors 2a to 2m whose speed is gradually increased, so that they are aligned in one line along the guide member 4.

The container 6 conveyed and collected by the collecting conveyor 2 has a vertical width Y and a horizontal width X different from each other, and has a substantially rectangular plane shape (see FIGS. 3 to 5).
(Refer to FIG. 3), the direction correcting device 8 according to the present embodiment aligns with the longitudinal direction facing forward and backward, and sends it to the next step.

The direction correcting device 8 is a conveyor 2m on the most downstream side of the collective conveyor 2 (hereinafter referred to as a main conveyor).
A narrow alignment conveyor 10 arranged in parallel along the conveyor 2m, and above the main conveyor 2m,
The alignment conveyor 10 and the conveyor guide 12 arranged on the opposite side are provided (in this embodiment, the conveyor guide 12 constitutes a part of the downstream side of the guide member 4 of the collective conveyor 2). The width W of the conveying surface 14 of the main conveyor 2m is limited by the conveyor guide 12 to a width that substantially matches the lateral width (narrower width) X of the container 6, and thus the vertical width Y of the container 6 is limited. Is wider than the width W of the transfer surface 14 of the main conveyor 2m, so that when the container 6 is in the lateral direction, it protrudes from the transfer surface 14 of the main conveyor 2m, and the main conveyor 2m and the alignment conveyor 1
It is designed to be spread over both 0s. The alignment conveyor 10 is operated at a higher speed than the main conveyor 2m, and is located at the same height as the main conveyor 2m on the upstream side (collecting conveyor 2 side) and gradually rises as it progresses to the downstream side. The upstream side is shown, and FIGS. 4 and 5 sequentially show the downstream side).

Next, the operation of the article direction correcting device 8 will be described. By the collecting conveyor 2, the articles 6 conveyed in multiple rows are collected in one row. The containers 6 are gathered in one line, but the direction is kept random and fed into the direction correcting device 8. The direction in which the containers 6 are to be aligned, that is, the containers 6 that have been fed with the longitudinal direction (wide vertical direction Y) facing forward and backward are the main conveyor 2m.
It is placed on the carrying surface of the sheet and is conveyed as it is (see 6a in FIG. 3).

The container 6 fed with its longitudinal direction oriented laterally, that is, with the narrow transverse direction X forward and backward, is placed across the main conveyor 2m and the alignment conveyor 10 (see 6b in FIG. 3). It is conveyed by both conveyors 2m and 10. Since the alignment conveyor 10 is moving forward at a speed faster than that of the main conveyor 2m, the orientation of the container 6 facing sideways is gradually changed (see FIG. 4). Moreover, since the aligning conveyor 10 gradually rises, the container 6 can be turned while being tilted, so that the container 6 is reliably rotated. Then, when the vertical direction of the correct direction is reached, the alignment conveyor 10
Depart from and completely move on the main conveyor 2m. After that, the aligning conveyor 10 that advances to the elevated position functions as a guide, and the containers 6 that are oriented in the correct direction.
To prevent it from turning again (see FIG. 5).

As described above, by providing the transport conveyor 10 along the main conveyor 2m, the traveling speed of which is higher than that of the main conveyor 2m, and the transport surface gradually rises from the same height as the main conveyor 2m, With such a structure, the container 6 can be reliably aligned in a fixed direction without requiring a large space.

In the above embodiment, the apparatus for correcting the direction of the container 6 having a rectangular planar shape has been described. can do. Even when the operating speed of the alignment conveyor 10 is slower than that of the main conveyor 2m, the direction can be corrected by rotating the articles in the opposite direction. Furthermore, by properly setting the speed relationship between the two conveyors depending on the difference in conditions such as whether the container is empty or full, it is possible to make a correct direction correction. Further, the alignment conveyor may be lifted once from the same height as the main conveyor and then returned to the original height.
