[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container carrying device, and more particularly to a container carrying device provided with a carrying-out means for carrying out a container from a hopper.

[0002]

2. Description of the Related Art Conventionally, as a container conveying device, one having the following structure is known. That is, carrying-out means for carrying out the container in the hopper to the outside of the hopper, a separating plate that is slidably movable in the hopper, and moves the contacted container in the hopper, and a drive for moving the separating plate. Those equipped with a mechanism are known. In such a conventional apparatus, the drive mechanism reciprocates the camellia plate along the carrying direction of the carry-out means, whereby the container in contact with the camellia plate is easily moved in the carry direction of the carry-out means. It is configured like.

[0003]

By the way, in such a conventional device, since the driving mechanism simply reciprocates the separating plate, noise and vibration are accompanied by the reciprocating movement of the separating plate by the driving mechanism. It has been pointed out that the drawback that occurs. In addition, the conventional device has a drawback that the number of containers carried out by the carrying-out means varies greatly depending on whether the separating plate moves forward or backward.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present invention is a carrying-out means for carrying out the container in the hopper to the outside of the hopper, a slanting plate that is slidably provided in the hopper and is movable so as to move the contacted container in the hopper,
In a container transporting device provided with a drive mechanism for moving the camellia plate, the drive mechanism is configured to circulate and move the camellia plate in one direction by drawing an elliptical movement locus on a flat surface. However, when the camellia plate moves to a position on the lower side of the movement locus, the container that comes into contact with the camellia plate is configured to be moved along the carrying direction of the carry-out means,
Further, when the separation plate moves to a position on the upper side of the movement locus, the container in contact with the separation plate is moved in a direction opposite to the carrying direction of the carry-out means.

[0005]

According to this structure, the camellia plate moves circularly while drawing an elliptical movement locus, so that the camellia plate moves smoothly as compared with the conventional case in which the camellia plate is simply reciprocated. . Moreover, at the position on the lower side of the movement locus, the container that has come into contact with the separating plate is moved along the carrying direction of the carrying-out means. On the other hand, at the position on the upper side of the movement locus, the container contacting the separating plate is moved in the direction opposite to the conveying direction of the discharging means. Therefore, the unloading operation of the container by the unloading means arranged on the lower side in the hopper becomes smooth. Therefore, it is possible to reduce the noise and vibration associated with the movement of the separating plate as compared with the conventional case.
