It is a state correction device.
[0009]
[Action]
The accommodation state correcting device according to claim 1 drives the vibration imparting means to swing the pair of left and right vibration imparting bodies in the left-right direction perpendicular to the transport direction of the transport conveyor with the support shaft as a center. Since the container is alternately brought into contact with the left bottom surface and the right bottom surface of the container to be conveyed, the container is repeatedly tilted left and right. That is, by alternately abutting the left and right vibration imparting bodies against the left bottom surface and the right bottom surface of the container, the entire container is tilted at a large angle toward one side and tilted at a small angle toward the other. Therefore, vibrations having different sizes are repeatedly applied to the entire container. Due to the vibration, the article is distributed substantially evenly with respect to the entire interior of the container, and is charged and corrected so as to be immersed below the peripheral edge of the opening side of the container. At the same time, when the container is tilted, either one of the left and right bottom surfaces is supported by the transport conveyor, and a transport force is always applied.
[0010]

The accommodation state correcting device according to claim 3 is in contact with the bottom surface of the container by attaching a plurality of rotating bodies to the abutting side end of the vibration imparting body in combination with the operation according to claim 1 or 2. The rotating body rotates in the transport direction, and the transport resistance applied to the container is reduced.
[0012]
【The invention's effect】
According to this invention, since the container tilts to the left and right while imparting vibration while transporting a container in which a large number of articles are stored, the article is charged and corrected so as to be immersed below the peripheral edge on the opening side of the container. The operation of closing the opening is surely and easily performed. In addition, since the containers are positively conveyed by the conveyance conveyor, the operation of correcting the accommodation state of the articles can be performed quickly and continuously, and the labor can be saved and the efficiency can be improved.
[0013]
Moreover, since the vibration imparting body that is eccentric and pivotally supported with respect to the center of the conveyance path is rotated in a direction in contact with the left and right bottom surfaces of the container, vibrations having different sizes are repeatedly imparted to the container, Each time the tilting is repeated, the gap between the articles is reduced, and the input can be corrected to a dense state.
[0014]
Furthermore, since the 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, and the conveyance speed can be prevented from decreasing. Furthermore, since the plurality of rotating bodies rotate in contact with the bottom surface of the container, almost no conveyance resistance is imparted to the container, and the container can be smoothly conveyed without stagnation.
