Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for vertically aligning containers in a process of producing or filling containers.

[0002]

2. Description of the Related Art In the process of producing or filling containers, alignment is performed to align the openings of the containers upward. 2. Description of the Related Art Conventionally, as a method of aligning containers, a method of manually detecting the direction of an opening of a container by some means and mechanically removing a downward container has been adopted.

[0003]

However, these methods have the problem that the processing capacity (number) is reduced due to the need for manual operation or the elimination of downward containers. Also, lightweight,
In the case of a container that is soft and easily deformed, there are problems such as that the container main body is deformed or the conveyance does not proceed smoothly in the method of mechanically removing the container. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a method and an apparatus for easily performing upward alignment of containers.

[0004]

According to the alignment method of the present invention,
A container alignment method characterized by lifting the container body by wind force from below on the perforated plate and inverting and aligning the container upward, wherein the aligning device has an upper surface made of a perforated plate, and both sides of the perforated plate. A box having a guide plate disposed at an end thereof, a blowing means for supplying air to the box, and a ventilation pipe extending from the blowing means to the box, wherein the hole direction of the perforated plate is at least 5% of the total number of holes. Is a container alignment device characterized by being inclined in the transport direction.

[0005]

In the aligning method of the present invention, the containers are lifted up by the wind force and are turned upside down, so that all the charged containers are lined up. In addition, since the containers are arranged in a non-contact manner, even in the case of a lightweight, soft and easily deformable container, the containers can be aligned without being deformed.

[0006]

The present invention will be described below in detail with reference to examples. FIG. 1 is a perspective view showing an embodiment of a container aligning apparatus according to the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.
The alignment device 1 includes a box 2, a perforated plate 3 on the upper surface of the box,
It is composed of guide plates 4 and 4 arranged on both side ends thereof and a blower tube 5 connected to the central bottom of the box. The blower tube 5 is a blower (not shown) having an air volume adjusting mechanism.
From the air to the box.

FIG. 3 is a partially enlarged sectional view of the perforated plate.
The perforated plate is provided with vertical holes 6 at regular intervals and holes 6 ′ (hereinafter referred to as “inclination holes”) having an inclination angle θ in the transport direction of the container. The number of the inclination holes is 5% or more of the total number of holes. To be. If the inclined holes are less than 5%, the transport of the container may not be smooth.

[0008] As the above-mentioned alignment device, a width of 20 cm and a height of 20 cm are used.
An acrylic plate having a thickness of 1 cm was used for a perforated plate on the upper surface in a box having a length of 100 cm and a length of 100 cm. Holes having a diameter of 5 mm were formed in the acrylic plate at a square pitch of 15 mm. For 10% of the perforated holes, the inclination angle θ in the transport direction was set to 20 °.

An aluminum foil container having an outer diameter of 90 mm and a depth of 30 mm was used, and the container was supplied to the aligning apparatus with all the openings facing downward. The volume of air from the blower was adjusted so that the container was not blown off. The containers were all turned upside down and discharged while flowing through the aligner.

Next, a plastic tray having an outer diameter of 100 mm and a depth of 6 mm was used, and the air volume was adjusted in the same manner as the previous time, and the containers were all supplied downward. At the exit of the array device,
All trays were upside down and aligned.

[0011]

According to the aligning method of the present invention, the container can be inverted and aligned without contacting the container. Therefore, even if the container is lightweight, soft and easily deformed, the container can be easily and reliably inverted without requiring any manpower. It is a method that can be aligned, and the device can be provided.
