It is characterized in that it is an attached accommodation state correction device.

[0010]

According to a first aspect of the present invention, the container is repeatedly tilted left and right by driving the vibration imparting means to abut the right and left bottom surfaces of the container conveyed by the conveyor. Vibration is applied to the entire container. Due to the vibration, the articles are substantially evenly distributed throughout the inside of the container, and are corrected so as to be immersed below the peripheral portion on the opening side of the container. At the same time, when the container is tilted, one of the left and right bottom surfaces is supported by the transport conveyor, and the transport force is constantly applied.

According to a second aspect of the present invention, in addition to the function of the first aspect, the accommodation state correcting device axially supports the vibration imparting member eccentrically with respect to the center of the conveying path of the conveying conveyor, and further includes the left and right bottom surfaces of the container. By being rotatable in the direction of contact with the container, when the container contacts the left and right bottom surfaces, the entire container is tilted toward one side at a large angle, and is tilted toward the other side at a small angle. Vibrations of different lengths are repeatedly applied.

According to a third aspect of the present invention, in addition to the operation of the first or second aspect, the accommodation state correcting device is provided on the bottom surface of the container by covering the contact surface of the vibration applying member with a member having low contact resistance.

The charging operation is corrected, and the operation of closing the opening of the container can be performed reliably and easily. In addition, since the containers are positively transported by the transport conveyor, the operation of correcting the storage state of the articles can be performed quickly and continuously, so that the labor can be saved and the efficiency can be improved.

In addition, the vibration imparting member, which is eccentrically supported on the center of the conveyance path, is rotated in a direction in which the vibration imparting member is brought into contact with the left and right bottom surfaces of the container. Each time the tilt is repeated, the gap between the articles becomes smaller, and the articles can be inserted and corrected in a dense state.

Further, since a member having a small contact resistance is brought into contact with the bottom surface of the container, the contact resistance applied to the container is small.
It is possible to prevent the transport speed from decreasing. Furthermore, since a plurality of rotating bodies are rotated while contacting the bottom surface of the container, the transfer resistance is hardly applied to the container, and the container can be smoothly transferred without stagnation.
