Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a garbage processing device that transfers garbage collected in a small container to a large container using a compactor.
The present invention relates to a method and device for detecting full capacity of a large container.

Generally, in garbage processing equipment installed at wholesale markets, etc., a small dump truck equipped with a small container collects the garbage, puts it into a compactor, compresses the garbage into a large container, reloads it, and transports it to a processing plant, etc. There are some things that I do.

In the above-mentioned garbage processing apparatus, the full capacity of the large container is conventionally detected by the number of reciprocating movements of a pushing plate provided in the compactor or the pressure of the pushing plate to push the garbage into the large container.

However, in the former method, it is necessary to make sure that the amount of dirt pushed by the pushing plate in one reciprocation is always constant, and in the latter method, there are problems such as a complicated mechanism such as a pressure detection device.

The present invention has been made in view of the above, and includes a method and method for detecting full capacity of a large container in a waste processing apparatus, which counts the number of times garbage is put into a compactor in a small container, and detects the full capacity of a large container based on the number of times. The present invention provides such equipment.

That is, in the method of the present invention, an approach path is formed on the upper floor of an installed compactor, a small dump truck carrying a small container tiltably enters the approach path, and the garbage collected from the small container is In a garbage processing device, the garbage is inputted into a compactor via a hopper, compressed and packed into a large container detachably connected to the compactor, and the dump truck tilts the small container backward to input the garbage. Then, the number of times the garbage is thrown in is counted, and each time a small dump truck enters and throws in garbage, it is counted.
After counting the set number of times, it will detect that the large container is full, and
A prohibition light is turned on to restrict future garbage disposal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the apparatus of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, reference numeral 1 denotes a garbage processing device, which compresses garbage collected in a small container 2 at a wholesale market or the like into a large container 3, and then transfers the garbage to a large container 3, in which a compactor 4 is installed. An approach path 6 for a small dump truck 5 is formed on the upper floor of the compactor 4.

The compactor 4 has an extrusion port 8 in the front face of the main body 7, an input port 9 in the upper part, and a push plate 10 that is slidable in the front and rear directions.

A shielding plate 11 that shields the input port 9 when moving forward is provided on the upper part of the pushing plate 10, and the rear end thereof is connected to the main body 7.
A hydraulic cylinder 12 connected to the main body 7 is connected at its front end, and the pushing plate 10 is pushed into the main body 7 by the expansion and contraction movement of the hydraulic cylinder 12.
A reciprocating tank inside.

move.

At the input port 9 of the compactor 4, there is a hopper 1 vertically extending upward.
3 are connected to each other, and the hopper 13 extends to the rear of the approach path 6, and an opening 14 is provided at the upper part of the hopper 14, which is inclined in a hollow manner and opens toward the approach path 6.

Furthermore, an extrusion port of the compactor 4. A large container 3 is removably connected to the container 8 through its push-in port 15, and the large container 3 is filled with garbage and loaded onto a large dump truck or the like for transportation.

The small dump truck 5 has the small container 2 mounted on its chassis so that it can tilt rearward at its rear end, and dumps garbage therein.

Collect.

The container full capacity detection device for detecting the full capacity of the large container 3 is provided with a detection means 16 at the end of the approach path 6, and the detection means 16 includes a photoelectric switch 17 erected via a pole 18. When the small dump truck 5 tilts the small container 2 backward, it is activated and detects the input of garbage.

Further, a prohibition light 19 is erected on the approach road 6, and the prohibition light 19
The amount of garbage equivalent to the full amount of large container 3 is in compactor 4.
It lights up when it is put in.

FIG. 2 shows the control system of the container fullness detection device, in which a detection circuit 20 connected to the detection means 16 sends a detection signal to a filling control circuit 21 and a counter circuit 22 by actuation of a photoelectric switch 17. .

The packing control circuit 21 controls the operation of the compactor 4, and the detection signal of the detection circuit 20 is inputted to the packing starting circuit 24 via the self-holding circuit 23.
4 starts the compactor 4. When the compactor 4 starts, it sends a signal to the filling end circuit 25 and also sends a clear signal to the self-holding circuit 23, and the filling end circuit 25 starts the compactor 4. When the process is completed, a signal is sent to the AND circuit 26.

The counter circuit 22 sends a signal to the AND circuit 26 when the number of detection signals generated by the detection circuit 20 reaches a set number of times. When the numerical value reaches a set number of times, a setting circuit 29 sends a signal to the AND circuit 26 and the lighting circuit 28 of the prohibition light 19, and the set number of times is set according to the capacity ratio of the small container 2 and the large container 3.

When the AND circuit 26 receives signals from both the stuffing control circuit 21 and the counter circuit 22, it sends a signal to the full alarm circuit 30, and the full alarm circuit 30 indicates that the large container 3 is full. , sends a signal to the container exchange circuit 31.

When the container exchange circuit 31 connects the empty large container 3 to the compactor 4, it sends a reset signal to the counting circuit 27 and a stop signal to the lighting circuit 28 and the full warning circuit 30.

Next, to explain the operation, in a state where the empty large container 3 is connected to the compactor 4, the small dump truck 5 that has collected garbage moves backward to the approach path 6, tilts the small container 2 backward, and then the compactor 4 4, the tilting of the small container 2 activates the photoelectric switch 17, and the detection circuit 20 issues a detection signal.

The detection signal causes the push plate 10 of the compactor 4 to reciprocate, compressing and packing the garbage into the large container 3, while the counting circuit 27 counts the number of transmissions of 1, that is, the number of transmissions of 1 by the small container 2 to the compactor 4. Count the number of times the garbage is added in step 1.

When the small container 2 finishes loading garbage, the small container 2 newly loaded with garbage is carried into the approach path 6, and the garbage is loaded into the compactor 4, and the detection circuit 20 issues a detection signal as described above, and the counting circuit 27 counts, and the compactor 4 operates.

When the next garbage is put in at the same time as the previous garbage is being packed, the detection circuit 20 generates a signal, which is self-held by the self-holding circuit 23, and then the stuffing start circuit is activated after the previous garbage is pushed in. 24 generates a signal, the push plate 10 continues to reciprocate, and the self-holding circuit 23 is cleared.

When the above operations are repeated in sequence and the number of calls counted by the counting circuit 27 reaches the set number, that is, when the number of times the small container 2 throws garbage into the compactor 4 reaches the set number, the setting circuit 29 makes a call and prohibits the operation. The light 19 lights up, the garbage is thrown in 4 preset times, which restricts further garbage feeding, the garbage is stuffed into the large container 3, and when the operation of the pushing plate 10 stops, the stuffing end circuit 25 sends a signal. AND circuit 26
The full capacity alarm circuit 30 issues an alarm, and the full capacity of the large container 3 is detected.

The full large container 3 is removed from the compactor 4, and the empty large container 3 is connected, and by replacing it, the container switching circuit 31 sends a signal, the counting circuit 27 is reset, and the prohibition light 19 and full warning are activated. stops.

In this embodiment, the small container 2 is a packing box of a small dump truck 5, but it may also be a garbage container of a garbage collection vehicle, or even a single container, and the feeding thereof need not be automatic or manual.

The large container 3 may also be placed on the vehicle platform.

Furthermore, the hopper 13 may be a dust chute to detect the number of times small containers are loaded from the input port on each floor.

As described above, according to the method of the present invention, the full capacity of a large container can be reliably detected by a simple method of detecting the full capacity of a large container based on the number of times garbage is put into the compactor of a small container. can be done efficiently.
