Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for selectively distributing and stacking granular articles into a plurality of containers arranged at predetermined positions.

A method for uniformly distributing and stacking bark, rice husk, sawdust, sludge, and other granular materials in multiple containers or tanks arranged without causing compaction is to move the supply position of the granular materials sequentially within the containers. There is also a method of stacking by sequentially pushing out a certain amount of material by spreading it over the entire container, and installing a gate device that opens and closes with a cylinder etc. in the loading area from the distribution conveyor to the loading conveyor. A method has been proposed for distributing food by opening only the gate section corresponding to the loading conveyor.

However, the above-mentioned loading method has the disadvantage that the loading device is complicated and consolidation occurs during extrusion, and the distribution method has the disadvantage that mechanical movable parts are prone to failure.

In view of this, the present invention aims to eliminate gate opening/closing, eliminate mechanically moving parts, and selectively distribute and stack a plurality of containers without causing consolidation.

The following description will be made based on the illustrated embodiment.

In the figure, reference numeral 1 denotes a container (or tank) for storing granular products, and this container may be arranged in a plurality of containers in parallel as shown in FIG. 1 or in a facing manner as shown in FIG. At the same time, one or more stacking conveyors 2 are arranged above each container.

This stacking conveyor 2 is provided in each container so that the granular articles are stacked uniformly over the entire container.

This stowage conveyor uses a trough conveyor configured to drive flights 2b, which are protruding from an endless chain, inside a horizontal trough 2a whose lower part, that is, the bottom of the upper part of the container is completely open.

A bottom plate 2c is provided at the bottom of a part of the stowage conveyor 2, that is, the part that protrudes from the containers, and the stowage conveyors 2, 2... A conveyor 3 is provided.

Like the stowage conveyor 2, this distribution conveyor 3 is also housed in a horizontal trough 3a and a flight 3b, and has one or more openings 3 at the bottom of the horizontal trough, which intersects with the stowage conveyor.
c.

In order to first load the granular articles into one of the containers in which the granular articles supplied to all the distribution conveyors 3 are lined up, for example, the upper container in FIG. 1, the distribution conveyor is driven (continuous operation) and When either one of the upper container stowage conveyors 2 is driven, the granular articles supplied to the distribution conveyor are transferred by flight movement within the trough of the conveyor, and the granular articles provided on each stowage conveyor are Since the opening 3c of the distribution conveyor is in an open state, the granular articles that fall through the opening 3c at the position of the driven stowage conveyor are sequentially smoothed by the top by the flight of the stowage conveyor and are moved inside the container toward the distribution conveyor side. More and more will be loaded.

This is loaded in one driving direction of the flight, that is, in the direction of the arrow in FIG.

When loading by flight is completed, fullness is detected by the fullness detection device No. 4, and the driving of the first stowage conveyor is stopped and the next stowage conveyor is driven.

In this way, if a container has two or more stowage conveyors, each of the stowage conveyors is driven in sequence or in an arbitrary order to load the container.

When one stowage conveyor is being loaded with granular goods, the other openings of the distribution conveyor are filled with items that have fallen earlier and are deposited in the trough of the stowage conveyor and near the opening of the distribution conveyor. Since the top surface of the stacked articles is apparently closed, after a certain amount of granular articles have fallen, they will not be loaded onto the loading conveyor unless the flight of the loading conveyor is driven.

In this way, when a container becomes full, it is detected by a fullness detection device such as a limit switch, phototube, or sensor.
All stowage conveyors for the first container are stopped and the stowage conveyor on the second container is driven.

The order of the containers to be loaded during loading can be arbitrarily selected either in permutation or in an arbitrary selection method, and this is repeated.

In the above-mentioned embodiment, there is only one distribution conveyor, but it is also possible to use two or more conveyors, and the direction of operation is not the same, but rather the distribution conveyor moves within the trough at the shortest distance from the article supply position. In some cases, the flight may be made to move forward or backward so that the article can be dropped into a predetermined container through the opening.

This also applies to loading conveyors, where the flights can be reversed or reversed.

According to the present invention, a hole is formed at a position corresponding to the stowage conveyor provided on each container to be stowed in the trough of the distribution conveyor, and the stowage conveyor is connected so that the bottom thereof is inside the container. Since the trough is opened at the trough, if only the stowage conveyor of the container to be stowed is driven, the goods will fall into the container from the opening at that position, but in the flight that is being driven, the goods will fall onto the stowage conveyor. The containers are sequentially stacked from the distribution conveyor side in the advancing direction of the stowage conveyor while leveling the bottom of the flight.

In this case, no consolidation of the stowed goods occurs.

In addition, by driving only the stowage conveyor installed on the container to be stowed and stopping the other stowage conveyors, the trough of the stowage conveyor can be moved first at the opening, especially at a position where loading is not being carried out. Since the flight does not move objects that have fallen into the container, the area immediately below the opening becomes full and is closed.

Furthermore, the gate provided in the trough opens and closes without any moving parts unlike mechanical systems, so there is no possibility of failure.

Furthermore, the stacking order can be arbitrarily selected, and the stacking can be automatically carried out using a fullness detection device.

[Scope of Claims] 1. A stowage conveyor equipped with troughs each having an open bottom is disposed horizontally above the containers to which granular articles are to be distributed and stowed, and a large number of these containers are arranged in a predetermined shape, and the stowage conveyor A distribution conveyor is disposed above and across between the stowage conveyors, and the granular articles supplied to the distribution conveyor are continuously driven by the distribution conveyor and only the stowage conveyor in the container to be loaded is continuously driven. The items are dropped one by one through the holes opened in the distribution conveyor, and are stacked one after another into containers while leveling them on the bottom surface of the flight of the stowage conveyor.
