[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a trash container transport device for a high-rise building, and more particularly to a trash container transport device for a high-rise building in which a trash capsule type flexible trash container packed in a synthetic resin sheet is dropped into a vertical transport pipe.
[0002]
[Prior art]
Conventionally, high-rise buildings such as condominiums are provided with a garbage container transport device. This garbage container transport device consists of a vertical transport pipe (dust chute) that penetrates a high-rise building up and down, a trash input device that throws trash into the vertical transport pipe, and a garbage storage tank installed at the lower end of the vertical transport pipe. Be composed. The garbage stored in a soft garbage container such as a plastic bag is thrown into the vertical transport pipe from the garbage input device on each floor, falls down the vertical transport pipe, is stored in the garbage storage tank, and is stored in the garbage storage tank. The waste is regularly transported by garbage trucks.
[0003]
[Problems to be solved by the invention]
However, when relatively low specific gravity and elastic garbage, such as cardboard, is stored in a soft garbage container and put into a vertical transport tube, the inner wall of the vertical transport tube and the soft garbage container When the frictional force between the garbage container and the garbage container is larger than the weight of the garbage container containing the garbage, there is a problem that the garbage container stops in the middle of the vertical transport pipe and clogs the vertical transport pipe.
[0004]
In such a case, if a garbage container containing garbage with a relatively high specific gravity happens to be subsequently thrown in from a higher floor, the garbage container with a high specific gravity may be clogged in the middle of the vertical transport pipe. It may collide with a garbage container and drop integrally to clear the clog. However, if the low-density garbage containers are continuously charged and a plurality of garbage containers are clogged in a stacked state, the overall frictional force becomes very large. However, this high-density refuse container also stops on the stacked low-density refuse container, and the clogging of the refuse container becomes even larger.In the end, the use of trash container transport equipment is prohibited, and workers must remove the clog. That situation must occur. In particular, if the user of the garbage container transport device does not notice the clogging of the vertical transport pipe, and then throws in garbage one after another and an extremely large amount of garbage containers are clogged in the vertical transport pipe, The work of removing the clog requires an extremely large amount of labor and time, and causes an increase in maintenance cost.
Therefore, an object of the present invention is to provide a high-rise building garbage container transport device that can automatically eliminate clogging of a loaded garbage container when the garbage container is clogged in the middle of the vertical transport pipe. .

[0006]
When the garbage container contacts the inner wall of the vertical transport tube while falling down the vertical transport tube, and the friction generated by this contact is greater than the weight of the garbage container, the garbage container gets stuck in the vertical transport tube. When such a garbage container is clogged, the clogging detecting means detects this and generates a clogging detection signal. In response to the clogging detection signal, the heavy load input means loads the heavy load into the vertical transport pipe, and the loaded heavy load falls almost freely in the vertical transport pipe and collides with the clogged trash container. As a result, the heavy object and the garbage container fall together in the vertical transport pipe. In this way, the clogging of the garbage container is automatically cleared by the introduction of heavy objects.

[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a high-rise building waste container transport apparatus according to the present invention will be described below with reference to FIG.
In FIG. 1, a refuse input device 2 is connected to a vertical transport pipe 1 installed in a high-rise building for each floor, and a soft trash container 3 made of synthetic resin containing garbage is transferred from the refuse input device 2 to the vertical transport pipe 1. It is thrown into. A pair of a light emitting source 4 and a photoelectric sensor 5 is mounted on the inner wall surface of the vertical transport pipe 1 at a position below each refuse input device 2. These light emitting sources 4 and photoelectric sensors 5 are arranged along the vertical transport pipe 1 at predetermined intervals in the vertical direction. Further, the light emitting source 4 and the photoelectric sensor 5 are opposed to each other in the diameter direction of the vertical transport pipe 1, and the photoelectric sensor 5 detects the soft trash container 3 falling on the vertical transport pipe 1 and generates a fall detection signal. The fall detection signal of each photoelectric sensor 5 is input to the control panel 7 via the line 6. The control panel 7 calculates the falling speed of the garbage container 3 based on the time when the drop detection signals of the upper and lower photoelectric sensors 5 are generated and the interval between the upper and lower photoelectric sensors 5.
[0017]
Thus, the photoelectric sensor 5 constitutes a fall detection sensor that detects the garbage container 3 falling on the vertical transport pipe 1 and generates a fall detection signal. In addition, such a drop detection sensor is not limited to the photoelectric sensor 5 and may be any sensor as long as the drop of the trash container 3 can be detected, for example, the pressure in the vertical transport pipe 1 caused by the fall of the trash container 3. A pressure sensor that detects a change, a proximity sensor that detects the approach of the trash container 3, and the like can also be used.
[0018]
An openable and closable bottom cover 8 is attached to the lower end of the vertical transport pipe 1, and the bottom cover 8 is driven to be opened and closed by a driving device 9 such as a cylinder. A pair of a pair of light emitting sources 10 and photoelectric sensors 11 is mounted on the inner wall surface of the vertical transport pipe 1 immediately above the bottom lid 8. The light emitting source 10 and the photoelectric sensor 11 oppose each other in the diameter direction of the vertical transport pipe 1, detect a falling object that lands on the bottom cover 8, and generate a landing detection signal in response to the detection. Thus, the photoelectric sensor 11 forms a landing detection sensor. Note that the landing detection sensor is not limited to the photoelectric sensor 11, and any sensor can be used as long as it can detect the landing of a falling object on the bottom cover 8, such as a pressure sensor, a proximity sensor, or the like. Further, a weight sensor for detecting a change in weight of the bottom cover 8 when a falling object lands on the bottom cover 8 can be used. In addition, the photoelectric sensor 5, the control panel 7, and the photoelectric sensor 11 constitute a clogging detection unit that detects that the refuse container 3A is clogged in the middle of the vertical transport pipe 1. Further, the clogging detecting means may be constituted by a plurality of photoelectric sensors 5 and a control panel 7.
[0019]
A belt conveyor 12 that is reciprocated by a driving device (not shown) is disposed below the bottom cover 8. A heavy-weight storage box 13 is provided at one end of the belt conveyor 12, and the other end of the belt conveyor 12 is provided at the other end. A garbage collecting unit (not shown) is installed in the unit. The belt conveyer 12 forms a sorting unit that is rotated forward and backward based on a command from the control panel 7, sorts the landed objects that have landed on the bottom lid 8, and transfers the sorted objects to the heavy goods storage box 13 and the garbage collecting unit.
[0020]
The uppermost portion of the vertical transport pipe 1 is vertically divided so as to form an opening 14, and a moving cylinder 15 is fitted into the opening 14. Constitute. The inner diameter of the moving cylinder 15 is substantially the same as the inner diameter of the vertical transport pipe 1 and can be moved in the horizontal direction. Cylindrical heavy storage tubes 18 and 19 are connected to both sides of the moving tube 15 by connecting members 16 and 17, respectively, and the inner diameters of these heavy storage tubes 18 and 19 are substantially the same as the inner diameter of the vertical transport pipe 1. It is. Heavy objects 20 are stored in the heavy object storage tubes 18 and 19, respectively. The heavy storage cylinder 18 is connected to a driving device 21 such as a cylinder, and the driving device 21 horizontally moves the heavy storage cylinder 18, the moving cylinder 15, and the heavy storage cylinder 19 integrally.
[0021]
The weight 20 has a spherical shape, and its diameter is 60% to 70% of the inner diameter of the vertical transport pipe 1. Also, the weight of the heavy object 20 is determined according to the weight of the garbage container 3 usually filled with garbage, which is put into the vertical transport pipe 1. For example, when the weight of the garbage container 3 with garbage is 5 kg to 30 kg, It is selected from 5 kg to 15 kg.
The moving cylinder 15, the heavy storage cylinders 18 and 19, and the driving device 21 constitute a heavy load input device 22 that loads the heavy load 20 into the vertical transport pipe 1.
[0022]
Next, the operation of this embodiment will be described.
The garbage container 3 introduced from the refuse introduction device 2 falls in the vertical transport pipe 1 and lands on the bottom cover 8. Thereafter, the bottom cover 8 is opened by the driving device 9, and the waste container 3 falls onto the belt conveyor 12. Each photoelectric sensor 5 detects the falling trash container 3 and generates a drop detection signal. Similarly, the photoelectric sensor 11 detects the landing of the trash container 3 and generates a landing detection signal. The control panel 7 calculates the falling speed of the refuse container 3 from the time intervals at which these drop detection signals are generated, and determines the time at which the trash container 3 should land, which is determined from the calculated trash container falling speed, or two to three. Within three times the time, it is determined that the above-mentioned landing detection signal has been generated, and it is confirmed that the garbage container 3 has landed normally. Thereby, the control panel 7 rotates the belt conveyor 12 forward, and discharges the trash container 3 on the belt conveyor 12 to a garbage collecting unit (not shown).
[0023]
If the waste container 3A introduced from the waste introduction device 2 is, for example, relatively lightweight and has a large volume, the waste container 3A comes into contact with the inner wall of the vertical transport pipe 1 during dropping, and the vertical transport pipe 1 is rubbed against the inner wall. In this case, the landing detection signal from the photoelectric sensor 11 is not generated despite the occurrence of the fall detection signal from any of the photoelectric sensors 5. When the control panel 7 detects that the landing detection signal is not generated within a predetermined time from the generation of the drop detection signal, the control panel 7 determines that this is a clogging of the garbage container 3 and sends a drive signal to the drive device 21 of the heavy loader 22. Send out. The drive device 21 drives the heavy storage cylinder 18 to the left according to the drive signal. As a result, the movable barrel 15 retreats from the opening 14 of the vertical transport pipe 1, and instead, the heavy article storage barrel 18 fits into the opening 14. Thereby, the heavy goods 20 stored in the heavy goods storage cylinder 18 are thrown into the vertical transport pipe 1. Since the diameter of the heavy object 20 is sufficiently smaller than the inner diameter of the vertical transport pipe 1 as described above, it falls almost freely without almost touching the inner wall of the vertical transport pipe 1, and It collides with the refuse container 3A that is stopped on the way. Due to this collision, the heavy object 20 and the refuse container 3A descend integrally and land on the bottom lid 8. Immediately after the loading of the heavy article 20, the heavy article loading apparatus 22 returns to the initial state, that is, the state in which the moving cylinder 15 is fitted into the opening 14 of the vertical transport pipe 1.
[0024]
The photoelectric sensor 11 detects the landing of the heavy object 20 and the garbage container 3A and generates a landing detection signal. The driving device 9 drives the bottom cover 8 to open, whereby the heavy object 20 and the garbage container 3A fall onto the belt conveyor 12. The control panel 7 determines that the heavy object 20 and the garbage container 3A have landed because the landing detection signal is generated within a predetermined time after the transmission of the drive signal to the heavy object input device 22, and the belt conveyor 12 is rotated in the reverse direction. Drive. Thereby, the belt conveyor 12 stores the heavy load 20 and the trash container 3A in the heavy load storage box 13.
[0025]
When the heavy load 20 is stored in the heavy load storage box 13, the control panel 7 performs an audio or visual display indicating the load. Thus, the administrator of the trash container transport device of the high-rise building takes out the heavy object 20 from the heavy object storage box 13 and refills the heavy object storage tube 18 of the heavy object input device 22 to prepare for the next clogging of the garbage container. . If the refuse container 3A is newly clogged before refilling the heavy load 20 into the heavy load storage cylinder 18, the driving device 21 of the heavy load input device 22 transports the heavy load storage cylinder 19 vertically. After moving to the opening 14 of the pipe 1, the heavy goods 20 stored in the heavy goods storage cylinder 19 are thrown into the vertical transport pipe 1.
[0026]
If the landing detection signal is not generated in spite of the first loading of the heavy load 20 described above, that is, if the clogging of the trash container 3A is not resolved, the control panel 7 drives the heavy load input device 22 again. A driving signal is sent to the device 21 to cause the movable barrel 15 to withdraw from the opening 14 of the vertical transport pipe 1, and instead fit the heavy storage barrel 19 into the opening 14. Thereby, the heavy goods 20 stored in the heavy goods storage tube 19 are thrown into the vertical transport pipe 1. The loaded heavy object 20 falls under its own weight in the vertical transport pipe 1 and collides with the refuse container 3A and the first heavy object 20 clogged on the way. As a result of this collision, the first and second heavy loads 20 and the refuse container 3A descend integrally and land on the bottom lid 8, thereby eliminating clogging. The subsequent operation is the same as that of the first heavy load.
[0027]
If the clogging has not been eliminated for some reason despite the second loading of the heavy load 20, the control panel 7 judges that no landing detection signal has been generated, A signal is generated to prohibit the use of all refuse input devices 2 and warn the administrator.
[0028]
In the above-described embodiment, when clogging cannot be eliminated by the introduction of the first heavy object, the second heavy object is introduced, and when the clogging still cannot be eliminated, an alarm is generated and the use of the refuse input device 2 is prohibited. Was something. However, the present invention is not limited to this, and when the clogging cannot be eliminated by charging the first heavy object, an alarm can be immediately issued and the use of the refuse input device 2 can be prohibited.
[0029]
【The invention's effect】
Further, in the above embodiment, the landing detection signal of the photoelectric sensor 11 is used to determine the clogging of dust. However, the photoelectric sensor 5 disposed above the photoelectric sensor 5 can be used instead of the photoelectric sensor 11. The control panel determines that the dust is clogged when the drop detection signal of the photoelectric sensor below it does not occur even after a predetermined time has elapsed after the generation of the drop detection signal of a certain photoelectric sensor.
As is apparent from the above description, according to the present invention, when a garbage container is clogged in the middle of a vertical transport pipe, the clogging detecting means detects this, and the heavy material input means responds to this detection, Into a vertical transport pipe to cause heavy objects to collide with the garbage container, thereby automatically eliminating clogging of the garbage container. Therefore, the use of the trash container transport device in a high-rise building is not prohibited, and the maintenance and management becomes very simple.
Further, since the configuration is relatively simple, the manufacturing cost and the maintenance cost are low.
