Description

Automatic unloading device, automatic unloading system comprising same and method for unloading articles from container

Technical Field

The present application relates generally to the processing of mail and mail parcels, express parcel items, and other cases and parcels.

Technical Field

An improved, more efficient high speed unloading system for unloading items from a container or trailer.

Disclosure of Invention

The application includes an automatic unloading apparatus, system, and method. The content of which comprises two basic parts:

1. the open container is formed from a band, which is not limited to woven articles, but is a band that is sufficiently flexible to allow crimping. Such as: a crimpable member formed from a chain; crimpable members formed from strips by hinging, and the like, fall within the category of belts. The open container formed by the band is mounted in a container such as a cargo box to constitute an outer container (for carrying) and an inner container (for carrying articles). The inner container is connected with the outer container through a bottom belt upper and lower rolling device, and the articles are stacked on the bottom belt.

2. The automatic unloading device comprises an upper port winding device, a lower port winding device, a conveyor, a side positioning plate, a buffer stopper, a buffer conveyor, a confluence conveyor and the like. The device is used for orderly, controllably and safely receiving the articles in the container.

3. The system consisting of the belt, the auto off-load device, and the operator console communicatively coupled to the controller is referred to as an auto off-load system.

In one embodiment, the open-ended container is formed by a belt, with the articles stacked on a base belt. The automatic unloading device is connected to the belt, separates the articles from the inner wall of the container by the side guide plates, and removes the first article by the conveyor, and the buffer stopper blocks and holds the second article among the plurality of articles after removing the first article, when the belt moves, the articles move together with the belt, and when the belt moves to a desired position. The upper and lower belt bottom winder makes the belt maintain the expected tension and controls the moving speed and the moving track of the article in linkage with the upper and lower belt port winder.

In another embodiment, when a first article is removed by the conveyor, the conveyor may descend to a next layer of articles according to the stack of articles and the first article is removed by the conveyor, and the buffer blocker blocks and holds a second article of the plurality of articles. Therefore, the stacked articles can be removed one by one, and the unloading operation is finished.

In yet another embodiment, an automatic unloading method, which is a belt-based inner container, provides for the movement of the articles by combining a bottom up and down take-up with a belt port take-up. And the automatic unloading device only removes the first article moved to the desired position. The controller is configured to control operation of the automatic unloading apparatus in response to an operator operating on the console.

The foregoing has outlined rather broadly the features and technical advantages of the present application so that those skilled in the art may better understand the detailed description that follows. Additional features and advantages of the application will be described hereinafter which form the subject of the claims. Those skilled in the art should appreciate that they may readily use the conception and the specific embodiment as a basis for modifying or designing other structures for carrying out the same purposes of the present application. Also, it should be further appreciated by those skilled in the art that such equivalent or similar constructions do not depart from the spirit and scope of the invention in its broadest form.

Detailed Description

Figures 1 through 3, discussed below, and the various embodiments for the principles described herein are by way of illustration only and should not be construed in any way to limit the scope of the present application. Those skilled in the art will understand that the principles of the present application may be implemented in the manufacture of any suitable arrangement. The innovations and principles of the present application will be described below with reference to exemplary, non-limiting embodiments.

Fig. 1 illustrates the placement of the strap forming container within the cargo box with the articles stacked on the bottom strap, with the strap 'moving' the articles on the strap by movement of the strap, thus eliminating the need for handling operations with static articles to effect movement of the articles. The belt bottom has upper and lower windups and the belt port has upper and lower windups that are linked to effect belt movement and to maintain a desired belt tension.

Fig. 2 depicts the process of the automatic unloading device unloading an item as it moves within the belt container to a desired unloading position.

FIG. 3 depicts the process of achieving automatic unloading by the controller, communicatively coupled by the operator station to the automatic unloading apparatus.

Claims

1. An automatic unloading device, characterized in that the automatic unloading device comprises:

the belt and the container form an opening container capable of moving relatively, and the movement of the articles is realized by the integral movement of the belt.

The port take-up and take-down mechanism moves the items within the cargo box as a unit and provides the belt with the desired tension.

The bottom up and down take-up mechanism, which provides the belt with the desired tension, is combined with the port take-up mechanism to provide the desired movement of the article.

And the side guide plates are inserted between the articles and the inner side wall of the container to separate the articles.

A conveyor removes a first article from the plurality of articles.

A buffer stop for stopping the plurality of articles during removal of the first article and for allowing layered unloading of the unloaded articles.
