Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for determining whether a container waiting in each container storage device is an empty container or a real container in a garbage transfer station having a plurality of container storage devices. The present invention relates to a method and device for determining whether it is true or not.

Generally, at a garbage transfer station, multiple container storage devices are installed so that multiple containers can be placed on standby, and when the garbage is transferred from the place where it is generated, the garbage is put into a compactor, compressed, and packed into containers. In rare cases, the container is loaded onto a transport vehicle and transported to a processing plant, etc. Empty containers are connected to a compactor to be filled with garbage, and actual containers are loaded onto a transport vehicle to be transported to a waste processing plant. It is necessary to determine whether a container waiting in a container storage device is an empty container or is actually a container.

Conventionally, this determination of whether a container is empty or actual has been made based on a worker's memory, or the container storage device has been differentiated into a container storage device dedicated to empty or real containers.

However, in the former case, the automation of the base will be incomplete as workers will be involved in the determination, and in the latter case, the number of empty or actual containers will not exceed the number of dedicated container storage devices. must be adjusted so that
There were cases in which all container storage devices could not be used effectively.

The present invention has been made in view of this point, and it is possible to use the container storage device effectively without distinguishing between empty containers or actual containers by determining whether the container is an empty container or a real container based on the weight of the container in each container storage device. The present invention provides a method for determining whether a container is empty or actual at a garbage transfer station, and an apparatus therefor, which enables accurate determination.

The basic idea of the method of determining whether a container is empty or real at a garbage transfer station according to the present invention is to install a compactor, and install a plurality of container storage devices for storing one container in a standby manner in a cross-shaped manner. At a garbage transfer station, empty containers are connected to a compactor and filled with garbage by moving the parent truck and child truck as appropriate to transfer the containers, while actual containers are loaded onto transport vehicles and transported. When a container is waiting in an individual container storage device, the weight of the container is electrically detected, the detected weight value is amplified, and then zero adjustment and gain adjustment are performed to adjust the container weight to a preset value. Comparing the classification weight value and the detected weight value with a comparator to determine whether the container is an empty container or a real container,
In addition to outputting information such as lighting up an indicator lamp, the output signal enables the selection of empty containers and real containers from among the stored containers, and the container to be moved can be selected according to the priority order of the preset program. This means that it is possible to automate garbage transfer stations.
