Description

[Detailed description of the device]

[0001]

[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used in the field of a dust storing and discharging machine that stores thrown dust and can automatically load it into a garbage truck or the like.

[0002]

[Prior art]

 Conventionally, in a dust storage and discharge machine installed in middle-high-rise housing, etc., the drum automatically rotates every time dust is thrown into the drum, and the thrown dust is moved in front of the drum. It is itself formed of a metal plate.

[0003]

[Problems to be solved by the device]

 Therefore, if the dust thrown into the drum contains empty cans, empty bottles, etc., when the drum rotates, the empty cans, empty bottles, etc. will hit the drum and a large resonance noise will be generated. It was prohibited to throw dust. Therefore, an object of the present invention is to provide a dust storing and discharging machine that can throw in dust even at night.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a dust storage and discharging machine in which the dust thrown into the drum is guided to the front of the drum by rotating the drum, and the rotation number of the drum is used as a day / night discriminating means. It is characterized by providing a rotation speed control means for making the nighttime smaller than the daytime by the rotation speed selection means.

[0005]

[Action]

 When dust is thrown into the drum at night, it is nighttime by the daytime / nighttime determination means, so the rotation speed selection means makes the rotation speed of the drum smaller than during the daytime, and the drum is rotated to move the thrown dust to the front of the drum.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a dust storing and discharging machine, which compresses and stores the thrown dust and loads it into a dust truck. The dust storing and discharging machine 1 is rotatably mounted on a pedestal 2 and has a drum 3 having a carrying blade (not shown) therein, and is connected to an opening 4 at the rear end of the drum 3 to be charged. A chute 7 having a closing lid 6 for opening and closing the mouth 5, a door 11 which is openably and closably opened by a cylinder 10 through a bell crank 9 to a discharge port 8 opened at the front end of the drum 3, and a lower front portion of the discharge port 8. , A conveyor device 12 for guiding dust in the drum 3 to the dust truck, a guide plate 13 for guiding dust in the drum 3 to the conveyor device 12, and a drum drive motor provided on the pedestal 2 below the rear end of the drum 3. 14, a loading stand 15 provided below the loading lid 6, a loading sensor 16 provided on the chute 7 for sensing dust thrown in, and a door closing mechanism which is turned on when the door 11 is closed. Sensor 17 and the front It is more configuration and control panel 18 provided to the frame 2.

A voltage lamp 19, a dust clogging lamp 25, a full lamp 26, etc. are provided on the front surface of the control panel 18, and it is selected whether the drum 3 is controlled manually or automatically. The selection switch 20, a counter 21 that counts and integrates the number of times dust is thrown in, a time switch 22 that distinguishes between daytime (6 am to 8 pm) and night (8 pm to 6 am), and It has an inverter 23 for rotating the drum drive motor 14 with an alternating current having an arbitrary frequency (HZ), a microcomputer for controlling the dust storage and discharge machine 1, and a program therefor.

The rotation speed of the drum drive motor 14 is proportional to the frequency (H Z) from the inverter 23, and is determined by the day / night discrimination means of the time switch 22 and the rotation speed selection means of the inverter 23. The rotation speed control means 24 is configured. The present invention having the above-mentioned construction will now be described in terms of operation. First, in FIG. 3, the power is turned on (step S1), the power lamp 19 is turned on (step S2), and the selection switch 20 (step S3) is set to the automatic side.

In FIGS. 1 to 3, an operator rides on the loading table 15 to open the loading lid 6, throws dust into the chute 7 through the loading port 5, and then closes the loading lid 6. The thrown dust is detected by the throw sensor 16 (step S4), and when the door sensor 17 is ON (step S5) and the door 11 is in the closed position, the counter 21 in the control panel 18 makes 1 UP (step S6). In the daytime by the time switch 22 (step S7), the inverter 23 outputs the frequency 60HZ (step S8), drives the drum drive motor 14 at 1800 rpm, and rotates the drum 3 at 6 revolutions per minute for 30 seconds (step S8). S10), and at night, the inverter 23 outputs the frequency 20 HZ (step S9), drives the drum drive motor 14 at 600 rpm, and rotates the drum 3 at 2 revolutions per minute for 30 seconds (step S10) to remove dust. It is compressed and stored in front of the drum 3.

At night, since the number of rotations of the drum 3 is small, the noise that an empty can or empty bottle in the dust hits the drum 3 and resonates is small, and it does not cause noise that would be annoying to residents in the vicinity. The steps S7 to S10 are controlled by the rotation speed control means 24.

Next, if the closing sensor 16 (step S11) is OFF, the process returns to the upstream of step S4, and if it is ON, the drum 3 is stopped (step S12), and the dust clogging lamp 25 is turned on (step S13). When the counter 21 reaches 50 (step S14), the drum 3 is stopped (step S15), and the full amount lamp 26 is turned on (step S16).

[0012]

[Effect of device]

 As described above, according to the present invention, when dust is thrown into the dust storage and discharge machine, the number of rotations of the drum at night is smaller than the number of rotations during the day. Since the noise that an empty bottle or the like hits the drum and resonates is small and does not cause noise that would be noticeable to residents in the vicinity, dust can be thrown in even at night.
