Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lifting system for collecting sorted garbage, and more particularly to a lifting system used for collecting garbage at a sorting stage in centralized management of garbage generated in a building.
[0002]
[Prior art]
In recent years, when centrally managing the waste generated in a building, vertical transport pipes (such as dust chutes) formed through multiple floors are used, and the garbage stored in a predetermined waste container is stored in this vertical transport pipe. There has been proposed a system that throws in and drops and collects, manages, and transports it at a lower position.
[0003]
These systems are disclosed in, for example, Japanese Patent Publication No. 60-286, Japanese Patent Application Laid-Open No. 63-252804, Japanese Patent Application Laid-Open No. 63-160904, and the like. Technology that makes the gap between them small, balances the gravity and air resistance of the waste container and adjusts the falling speed to make it softly land at the lower position, and also in the middle of the vertical transport pipe Techniques for providing an air rising area in the area and adjusting the fall speed more favorably are shown.
[0004]
In the centralized management of garbage using such vertical transport pipes, it will be necessary to collect the fallen waste containers at the lower position and transport them to the waste treatment facility. It becomes. For this reason, for example, a system is used in which a fallen waste container is automatically transferred using a belt conveyor or the like, and is sorted and collected for each type of garbage at a predetermined position.
[0005]
[Problems to be solved by the invention]
In sorting and managing waste containers that contain such waste, the system that collects the waste by dropping it downward from the transfer means for automatically transferring the waste container at a predetermined height position is easy to configure the structure and work. However, in this case, a predetermined number of various types of garbage are dropped at the respective locations. For this reason, a predetermined height difference is required between the place where the garbage is collected and the automatic transfer means, but there is a possibility that the garbage container will be damaged by the fall from the predetermined height and the internal garbage will jump out. In addition, although garbage such as bins stored in garbage containers may be destroyed at the time of dropping, it is necessary to collect such containers without destroying them. There was a problem of performing with less impact at the time.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its purpose is to ascend / descend the sorted garbage that can be received and collected by always dropping the garbage automatically transferred at a predetermined height position with a small impact. To provide a system.
[0007]
[Means for Solving the Problems]
Lifting system for sorting refuse collection according to claim 1 includes a vertical transport pipe predetermined bin previously prescribed for each type of waste is accommodated through each floor of the building to be turned, inserted from the vertical transport pipe Elevating system for sorting waste collection , comprising: a transfer means for transferring the garbage container at a predetermined height position; and a dropping mechanism for dropping the garbage container from the transfer means and sorting the garbage container in the transfer process by the transfer means. A waste receiving portion for receiving the sorted waste container at a predetermined position below the transfer means, a lifting means for raising and lowering the waste receiving portion, and the waste receiving portion when the waste container is put into a vertical transport pipe The number management unit for recognizing and managing the number of the garbage containers received at the number, and the number of the garbage containers received by the garbage reception unit based on information from the number management unit A height adjusting unit that controls the lifting and lowering unit so that the height position of the dust receiving unit is lowered downward by a predetermined height each time the number is increased to the number set in The falling distance of the garbage container from the means to the garbage receiving part can be adjusted.
[0008]
As a result, in the process of changing from the empty state where the garbage container is not present in the garbage receiver to the state where the garbage container is gradually accumulated, the collection of the garbage is performed while maintaining the falling height of the garbage container from the transfer means substantially constant. Can be done.
[0009]
That is, it is set at a high dust receiving position in an empty state, and when a predetermined number of garbage containers have accumulated, the height of the garbage receiving portion is lowered correspondingly, so that the falling height of the garbage container can be appropriately set. For example, a smooth drop operation can be secured, and the contents can be kept at a minimum height that is not damaged.
[0010]
In addition, when the number of garbage containers received by the garbage receiving unit reaches a number of a plurality of stages set in advance, a height adjusting unit is configured to lower the garbage receiving unit by a predetermined height. by so controlling the lifting means, without complicated control can be achieved with falling waste containers without slipping, the continuation holding small drop height.
[0013]
The sorting garbage collection lifting system according to claim 2 is provided with a slip assist part that is inclined downward from the transfer means toward the garbage receiver between the transfer means and the garbage receiver. The container is characterized in that it slides on the slip assisting part and falls to the garbage receiving part. Thus, it is possible to alleviate the impact at the time of drop of the dust container to the dust receiving portion from shifting transmission means. Accordingly, it becomes easy Ri good height adjustment control of the dust receiving portion.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 conceptually shows an example of a building garbage central control system using a vertical transport pipe (dust chute).
[0016]
As shown in the figure, in a building 100 having a plurality of floors, vertical transport pipes 10 penetrating each floor are installed at predetermined locations, and garbage stored in a predetermined waste container is dropped into each vertical transport pipe 10 from each floor. It can be made to. In the present embodiment, the dropped garbage container 200 is moved to an underground garbage sorting area, and is automatically moved and moved on the horizontal movement device 12 configured by a belt conveyor.
[0017]
In the embodiment of the present invention, the transfer means 12 is installed. For example, 14 to 20 in the figure are sorting garbage collection elevating systems. In other words, the garbage container 200 that is automatically transported on the moving means 12 has its kind of garbage managed in advance, and it is dropped from the upper position of the lifting system for collecting that kind of garbage, and the sorted collection of garbage is performed. Is to be done. For example, the garbage container 200-1 shown in the figure is collected in the lifting system 18 portion by dropping downward at a position above the lifting system 18. In addition, each garbage container collected in each part of this each raising / lowering system 14-20 is carried out using a vehicle etc. in the arrow 300 direction, for example.
[0018]
FIG. 2 shows an example of an ascending / descending system for collecting waste according to the present embodiment. As shown in the figure, the elevating means is formed of a fork lifter 22 and moves the elevating moving body 26 up and down by expansion and contraction of the hydraulic drive means 24. In the present embodiment, the raising / lowering operation is performed with the chain 28 interposed. A fork claw (not shown) protrudes from the elevating moving body 26 and is engaged with an elevating pallet 30 which is a garbage receiving portion to raise and lower it.
[0019]
As shown in the figure, a garbage container 200 that has been automatically transferred on a belt conveyor 32, which is a moving means, is dropped and stored on a lift pallet 30. The belt conveyor 32 is provided with a dropping mechanism 34 for dropping the transferred waste container 200. The dropping mechanism 34 is provided with a moving plate 36 that moves in a direction substantially perpendicular to the traveling direction of the belt conveyor 32, and the moving plate 36 moves horizontally in the direction of arrow 400 by a hydraulic drive mechanism 38. By this moving operation, the garbage container 200 is pushed out and dropped onto the lift pallet 30. In order to improve the directionality of the drop, the inclined plate 40 which is a sliding assist portion is formed so as to protrude from the outer side of the belt conveyor 32 to the fork lifter 22 side.
[0020]
Note that a fence frame 25 is fixedly installed on the frame body 23 of the fork lifter 22 at a position above the fork lifter 22 so as to prevent the falling garbage container 200 from falling outside.
[0021]
Further, a carriage 42 is provided as a means for transporting the lifting pallet 30, and the carriage 42 is formed with a fence 44 around it so that the garbage container 200 is not spilled from above the lifting pallet 30. Yes. Although the illustration of the fence 44 on the fork lifter 22 side is omitted in the drawing, it is formed in a shape that does not hinder the vertical movement of the fork pawl of the fork lifter 22.
[0022]
When setting the elevating pallet 30, the carriage 42 passes under the belt conveyor 32 and travels toward the fork lifter 22 from the direction of the arrow 500, and is pulled out in the opposite direction after collecting the garbage. Is.
[0023]
Next, the operation according to the present embodiment will be described based on the flowchart shown in FIG. 3 and the operation diagrams of FIGS. 4-9, the same code | symbol is attached | subjected to the element similar to the structure shown in FIG.
[0024]
First, in step (hereinafter simply referred to as “S”) 101 in the flowchart of FIG. 3, the lifting pallet 30 is set. This state is shown in FIG. 4, and the carriage 42 on which the elevating pallet 30 is placed is moved in the direction of the arrow 500 as shown. Note that the fork lifter 22 of the fork lifter 22 has two fork claws 27 protruding at a position facing the traveling carriage 42.
[0025]
FIG. 5 shows a state in which the carriage 42 is pushed into the fork lifter 22 and the fork pawl 27 is inserted into the elevating pallet 30 to be locked.
[0026]
Next, in S102, an ascending operation for raising the elevating pallet 30 to the uppermost position is performed. FIG. 6 shows a state in which this raising operation is performed. When it rises to this state, the waste container dropping operation of S103 is performed. That is, the garbage container 200 is pushed out toward the elevating pallet 30 by the horizontal movement of the moving plate 36. Although the garbage container 200 falls, since the pallet 30 is at the uppermost position, the drop is not so large, and the destruction of the garbage in the garbage container is prevented.
[0027]
Next, in S <b> 104, it is determined whether or not the number of garbage containers 200 that have dropped on the lift pallet 30 has reached a preset first set number. Here, when the first set number is not reached (No), the process returns to S103 again and the waste container is dropped. If the first set number has been reached (Yes), the first-stage lowering operation is performed in S105.
[0028]
That is, the lowering operation from FIG. 7 to FIG. 8 is performed, and thereby the next dropping operation shown in S106 becomes possible. That is, the garbage container 200-2 indicated by a broken line in FIG. 8 can be dropped. Here, the lowering operation of the first stage is set so that the drop in the next drop of the garbage container 200-2 does not become so large, so here also the destruction due to the impact due to the fall of the dust inside is effective. Has been prevented.
[0029]
Next, in S107, it is determined whether or not the number of garbage containers 200 stored on the lift pallet 30 has reached the second set number. If this number has not been reached (No), S106 is determined. The dropping operation is performed again. When the set number has been reached (Yes), the second-step descending operation is performed in S108.
[0030]
In the present embodiment, the elevating pallet 30 is returned to the lowermost position by the lowering operation of the second stage. FIG. 9 shows this state, and in this state, the waste container 200 is dropped in the final stage, and the collection of the waste container 200 by the elevating pallet 30 is completed. Then, the carriage 42 on which the lifting pallet 30 loaded with the garbage containers 200 is loaded is pulled out in the direction of the arrow 600 and placed on the next-stage transport route (S109) (see FIG. 9).
[0031]
As described above, in this embodiment, the lifting pallet 30 started from the uppermost position is sequentially lowered according to the number of garbage containers 200 dropped on the pallet 30 to keep the dropping distance from the belt conveyor 32 as small as possible. It is possible to collect waste containers.
[0032]
Here, various configurations can be considered for the management of the number of falling containers 200. For example, when the garbage container 200 is introduced from each floor, the type of the internal garbage is input by using a keyboard. Information is sent to the CPU of the management system. When this waste container 200 falls and moves onto the belt conveyor 32 at the waste sorting stage, the number of the waste containers 200 is managed for each type by the CPU of this centralized management system. Based on the signal, the control unit of the fork lifter 22 (not shown) can adjust the vertical movement of the elevating moving body 26 according to the number of the lifter 22.
[0033]
It is also possible to install detection means for detecting that the garbage container 200 has passed between the fork lifter 22 and the belt conveyor 32, and thereby count the number of the garbage containers 200 that have passed. .
[0034]
Furthermore, in the present embodiment, the lowering operation control of the fork lifter 22 is performed according to the number of the fallen garbage containers 200, but the present invention is not limited to this method. For example, a mechanism on the fork lifter 22 side, for example, a fence frame 25, fork lifter frame 23, and the like are installed by installing a sensor for detecting the height position of garbage container 200 collected on elevating pallet 30, for example, an optical sensor such as an infrared sensor at every predetermined height position. It is also possible to detect the height position of the waste container 200.
[0035]
It is also possible to sequentially lower the elevating pallet 30 by checking the height position. According to such a control method, the position of the lifting pallet 30 is always appropriately set to an appropriate position when there is a case where the garbage container 200 is piled up depending on how the garbage container 200 is dropped or the situation where the garbage container 200 is offset. It is also possible to make correction moves.
[0036]
In addition, this invention is not limited to the structure shown to said each embodiment, A various deformation | transformation is possible within the range of the summary of invention. For example, in the embodiment shown in FIG. 4 to FIG. 9, the fork lifter 22 is lowered in two stages. This is appropriately set according to various conditions such as the height of the belt conveyor 32 and the size of the waste container. Is.
[0037]
【The invention's effect】
As described above, according to the sorting waste collection lifting system according to the present invention, when waste is collected and managed in a situation where waste is collected and managed, it is dropped and collected. Since the position can be adjusted according to the amount of collected garbage, the impact during dropping is reduced by an appropriate drop while ensuring a drop-free operation without stagnation, and the destruction of garbage inside the garbage container. Can be effectively prevented. As a result, the waste container is prevented from being damaged during the waste sorting process, and the collection and management of the waste using the vertical transport pipe is improved.
