[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust loading control device for efficiently filling a container with dust loaded from a hopper.

[0002]

2. Description of the Related Art Generally, at a refuse relay station, in which refuse collected by a garbage truck is loaded into a container and transported to a final disposal site, etc., the refuse dropped from the garbage truck to a hopper is The dust is loaded into a predetermined area in the longitudinal direction of the inside of the container from the input port of the hopper to load the dust into the container.

[0003]

However, since the input port of a normal hopper corresponds only to a predetermined region in the longitudinal direction of the inner dimension of the container, the dust thrown in through the input port of the hopper will not fit in the inner dimension of the container. Despite reaching the height-direction full position only in the longitudinal-direction predetermined area of the container, it may not reach the height-direction full position in the longitudinal-direction predetermined area of other container inner dimensions. The loading of dust is very inefficient.

The present invention has been made in view of the above points, and an object thereof is to allow dust to be uniformly loaded into each predetermined region in the longitudinal direction of the inside dimension of the container and to put the dust into the container. It is to improve the loading efficiency of dust.

[0005]

A control device that operates the actuator so as to move the conveyor device to a next predetermined area in the longitudinal direction of the inner dimension of the container.

[0007]

With the above construction, in the invention according to claim 1,
The dust collected by the dust truck or the like is thrown into a predetermined region in the longitudinal direction of the inside dimension of the container through the throwing port of the hopper. Then, when the detection device detects that the dust thrown into this predetermined area has reached the container inner dimension height position full position, the control device operates the actuator to move the mounting table in the container inner dimension longitudinal direction. While moving to the next predetermined area, the actuator is stopped in the next predetermined area, and the dust is thrown through the slot of the hopper until the dust reaches a full position in the height direction of the inside of the container. Repeat sequentially in the area.

As a result, it is possible to solve the problem that the height-direction full position is reached only in the longitudinal predetermined region of the inner dimension of the container, but the height direction full position is not reached in the other longitudinal predetermined regions. The dust can be loaded into the container substantially uniformly in a plurality of predetermined regions in the longitudinal direction of the inner dimension of the container.

According to the second aspect of the present invention, the dust collected by the dust collecting vehicle or the like is thrown into the upstream end side of the conveyor device through the input port of the hopper, and then the downstream end side of the conveyor device. As a result, it is thrown into a predetermined area in the longitudinal direction inside the container. Then, when it is detected by the detection device that the dust thrown into this predetermined area has reached the height direction full position of the container inner dimension, the control device activates the actuator to move the conveyor device in the longitudinal direction of the container inner dimension. While moving to the next predetermined area, the actuator is deactivated in the next predetermined area, and the dust is thrown from the downstream end side of the conveyor device until reaching the full position in the height direction of the inside dimension of the container in this predetermined area. This is repeated in subsequent predetermined areas.

As a result, the problem that the height direction full position is reached only in the longitudinal predetermined area of the inside dimension of the container and the height direction full position is not reached in the other longitudinal predetermined areas is eliminated, and the inside of the container is eliminated.

At that point, the container is repeatedly moved to the next predetermined area one after another, eliminating the problem of loading dust into the container that has not reached the full height position in a plurality of predetermined areas in the longitudinal dimension of the container. However, the dust can be loaded almost uniformly in a plurality of predetermined regions in the longitudinal direction of the inner dimension of the container, and the loading efficiency of the dust in the container can be improved.

According to the second aspect of the present invention, the dust loading control device is located at a full position in the height direction of the dust that has been loaded into a predetermined area in the longitudinal direction of the inner dimension of the container from the loading port of the hopper via the conveyor device. When it reaches, the conveyor device is repeatedly moved to the next predetermined area in the longitudinal direction of the container inner dimension, so that the problem of loading dust into the container is eliminated in a plurality of predetermined areas in the longitudinal direction of the container inner dimension. The dust can be loaded almost uniformly, and the loading efficiency of dust in the container can be improved.

Next, a second embodiment of the present invention will be described with reference to FIG.

The second embodiment is a further improvement of the dust loading control apparatus of the first embodiment. The same parts as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

That is, in this example, the input port 2 of the hopper 2
Between the lower part of a and the container C, a conveyor device 7 that is movable in the longitudinal direction of the container inward dimension so as to sequentially inject dust into a plurality of predetermined regions in the longitudinal dimension of the container inward dimension, Hydraulic cylinder 8 as an actuator for moving the conveyor device 7 in the longitudinal direction of the inner dimension of the container
When the detection device 5 detects that the dust thrown in from the input port 2a of the hopper 2 has reached the height-direction full position in the container C, the control device 6 causes the conveyor device 7 to move the conveyor device 7 to the inside of the container. The hydraulic cylinder 8 is operated so as to be sequentially moved to the next predetermined region in the longitudinal direction.

The container C is immovably fixed on the ground G in a state where it is unloaded by the container carrier B. Further, the opening / closing door 21 provided in the input port 2a is loaded with the hydraulic cylinder 22 which is expanded and contracted by the control device 6 to dispose the empty container C on the ground G, and the first predetermined region in the longitudinal direction of the inner dimension of the container. The opening operation can be performed only after reaching the full height position in the final predetermined area (rear end area) in the longitudinal direction of the inner dimension of the container after being positioned in the (front end area shown in the figure). There is.

The conveyor device 7 comprises a belt conveyor, the upstream end of which is located below the input port 2a of the hopper 2, while the downstream end is the opening Cb of the container C.
It is located above and is set to have a width larger than the input port 2a of the hopper 2 so that the dust thrown in from the input port 2a of the hopper 2 can be smoothly received without dropping. The width of the container C is set to be smaller than the width in the lateral direction of the container C so that the container can be charged smoothly. A drive device (not shown) for driving the conveyor device 7 is similar to the opening / closing door 21 in that an empty container C is placed on the ground G and a height direction full position is set from a first predetermined area to a final predetermined area. It is designed to be driven only until it reaches. In addition, the detection device 5
Is provided on the lower surface of the conveyor device 7 on the downstream end side.
Further, at the upper position on the downstream end side of the conveyor device 7,
A can compression conveyor device 71 that compresses dust such as empty cans, which are input through the input port 2a of the hopper 2, on the conveyor of the conveyor device 7 is arranged oppositely, and a bulky empty can or the like is smoothly compressed. It is like this.

Further, the hydraulic cylinder 8 is constructed so as to slide the conveyor device 7 together with the can compression conveyor device 71 in the conveyor conveying direction (left and right direction in the figure), and the first front end region of the container C is moved. When the detection device 5 detects that the dust has reached the height-direction full position at the first reference position corresponding to, the control device 6
Thereby extends the hydraulic cylinder 8 to the second reference position where the downstream end of the conveyor device is located in the next predetermined region (central region), and the can compression conveyor device 71 and the conveyor device 7
Is slid to the upstream side in the conveyor conveying direction, the hydraulic cylinder 8 is extended to the third reference position where the downstream end of the conveyor device is located in the last rear end region of the container C, and the reference positions for a plurality of predetermined regions are changed. Are performed sequentially. In this case, the hydraulic cylinder 8 is in a shortened state at the first reference position where the downstream end of the conveyor device 7 is positioned in the first predetermined area of the container C.

As a result, the dust collected by the dust collecting vehicle A is thrown into the conveyor device 7 at the first reference position through the input port 2a of the hopper 2 and then conveyed on the conveyor device 7. An empty can or the like is loaded into the front end region of the container C in a state of being compressed by the can compression conveyer device 71, and the dust thrown into this front end region has reached the container inner size height position full position. When it is detected by the detection device 5, the control device 6 restricts the further injection of dust into the front end region, and the hydraulic cylinder 4 operates to move the conveyor device 7 and the can compression conveyor device 71 to the second and third reference positions. The hoppers 2 are thrown in through the conveyor device 7 until the dust reaches the full position in the height direction of the inside of the container even in the central region and the rear end region inside the container by moving the dust sequentially. Repeating the introduction of dust from 2a.
For this reason, the problem that the height direction full position is reached only in a single predetermined area, but the height direction full position is not reached in the other predetermined areas, is reliably solved, and the container C is filled. Since the dust can be loaded almost uniformly in a plurality of predetermined regions in the longitudinal direction of the inner dimension of the container, the efficiency of loading the dust into the container C can be similarly improved.

The present invention is not limited to the above-mentioned embodiments, but includes various modifications. For example, in each of the above-described embodiments, the predetermined area of the container C is three, but it may be divided into two or four or more predetermined areas.

In each of the above-mentioned embodiments, the dust from the dust collecting vehicle A is directly dropped onto the hopper 2. However, the dust is indirectly dropped onto the hopper via a screw device for conveying the dust while stirring or a conveyor device. Needless to say, it may be done.
