DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container transport device, and more particularly, to a container transport device for transporting containers from a hopper containing a large number of containers and transporting the containers downstream.

[0002]

2. Description of the Related Art Conventionally, there has been known a container transporting apparatus in which a container in a hopper is transported to a downstream side by being transported out of the hopper by a transporting means (for example, see Japanese Patent Application Laid-Open No. H05-1993).
319551). In such a conventional apparatus, the unloading means is constituted by a single unloading conveyor horizontally supported, so that the container placed on the unloading conveyor is transported and unloaded outside the hopper. I have. At that time, conventionally, a rotating blade is arranged above the carrying process of the carry-out conveyor, and a space in which only one container in a rolled state can pass between the tip of the rotating blade and the mounting surface of the carry-out conveyor. It is formed. Therefore, according to the conventional container transport device, the container in a state where a plurality of layers are superimposed on the unloading conveyor is engaged with the tip of the rotary wing in the process of being unloaded by the unloading conveyor and is pushed back in the transport direction. Become like Therefore, the container on the unloading conveyor that has passed the position of the rotary wing is rolled over in one layer and is transported toward the downstream side.

[0003]

By the way, as described above, in the prior art, the rotating blades are engaged with the stacked containers on the carry-out conveyor, and the overlapping upper containers are pushed back to the rear in the transport direction. Therefore, there is a drawback that the container is caught between the tip of the rotor and the mounting surface of the carry-out conveyor. In addition, conventionally, when the size of the container to be processed is changed, it is necessary to replace the size of the rotary wing according to the size of the container, and the replacement work has been complicated.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present invention is directed to a container transport device configured to transport a container in a hopper to the outside of the hopper by an unloading unit and transport the container to a downstream side, wherein the unloading unit is substantially V-shaped in cross-section by mutually adjoining sides. A first delivery conveyor, which is constituted by an unloading conveyor and guide means arranged at an angle, is provided downstream of the unloading means and is capable of mounting only one vertical row of containers, and is provided at an angle. Another delivery conveyor or a plate-shaped engagement member is provided at an angle along one side of the conveyor where the height is low, and the first delivery conveyor and the another delivery conveyor or the first delivery conveyor and the engagement member are connected to each other. Are arranged so as to have a substantially V-shaped cross section, and first detecting means for detecting that the containers are stacked in two or more stages on the first delivery conveyor is provided, and the first detecting means is provided on the first delivery conveyor. Container on top When it is detected that the containers are stacked in more than one stage, first pushing means for dropping the containers in the second stage or more from the first delivery conveyor is provided, and a collection chute for collecting the containers dropped from the first delivery conveyor is provided. It is provided.

[0005]

According to such a configuration, since the carrying-out means is constituted by the carrying-out conveyor and the guide means arranged so as to be inclined at a substantially V-shaped cross section, a state in which a large number of containers are accommodated in the hopper. Even in this case, the container can be smoothly carried out of the hopper with the container being sandwiched between the carry-out conveyor and the guide means. Further, even if two or more containers are placed on the first delivery conveyor, the second or more containers can be dropped from the first delivery conveyor by the first pushing means. by this,
The containers unloaded from the hopper can be arranged in a single row in a vertical direction. For this reason, unlike the related art, there is no occurrence of a problem in which the container is caught between the rotor and the conveyor. Therefore, the container can be prevented from being caught and the speed of unloading the container from the hopper can be increased.
