Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a separate garbage collection vehicle that separates and collects resource waste discharged from a retail store such as a convenience store in a single collection.
[0002]
[Prior art]
In general, convenience stores sell a wide variety of products, and the sales policy is to dispose of expired foods. Therefore, the resource waste discharged from convenience stores includes empty cans, empty bottles, In addition to plastic bottles, cardboard, and plastic containers, there are expired food packaging containers.
[0003]
Out of the resource waste discharged from the convenience store, empty cans, empty bottles, PET bottles, cardboards, and plastic containers are sorted for each item in the convenience store, and the packaging containers with expired foods are discarded as they are.
[0004]
In order to collect resource waste discharged from convenience stores, each convenience store is visited by garbage trucks and flat trucks, and collected by the garbage collected by the garbage collection trucks and flat trucks. The packaging containers with expired foods are collected as they are without being sorted into packaging containers and garbage.
[0005]
In JP-A-5-319505, a container box that can be dumped rearward is mounted on a vehicle body, the interior of the container box is formed in a plurality of separate collection chambers arranged in parallel in the vehicle width direction, and above each separate collection chamber. A separate garbage collection vehicle is described in which a screw conveyor is arranged, an input box is connected to the rear of the storage box, and recyclable waste such as empty bottles is efficiently collected and discharged separately.
[0006]
In Japanese Patent Laid-Open No. 11-3333155, a half drum body is provided in a case provided with an inlet, a rotating shaft provided with a rotating blade is provided in the drum body, and the packed food is separated into packaging material and waste food. Describes a separation and pulverization apparatus for separately discharging separated packaging materials and waste foods.
[0007]
[Problems to be solved by the invention]
Resource waste discharged from convenience stores is separated and collected by garbage collection trucks and flat trucks, but there is a limit to the number of convenience store stores where garbage collection trucks and flat trucks can circulate in one day. In addition, because there is a small amount of each kind of resource waste discharged from convenience stores, when collecting garbage for a day with a garbage truck or flat truck, it is necessary to load the garbage truck or flat truck with a lot of resource garbage. There is almost no problem, and there is a problem that the collection of each garbage with a garbage truck or flat truck is inefficient.
[0008]
In addition, when separating and collecting resource waste from each store using a plurality of garbage trucks and flat trucks, there is a problem that labor costs and vehicle maintenance costs increase.
[0009]
In addition, when a packaging container containing a food with expired expiration date is incinerated as it is, dioxins generated during the incineration of the container are a problem, and when it is disposed in a landfill, there is a problem in securing a landfill.
[0010]
Moreover, although the said separation garbage truck can collect and collect empty cans and empty bottles, it is not so popular because of its complicated structure and high manufacturing cost.
[0011]
Furthermore, since the separation and pulverization apparatus is a stationary type and is installed as a dedicated machine for each store, it has many problems such as cost, safety management, and hygiene management.
[0012]
The present invention has been made in view of the above points, and separates and collects all resource garbage that is taken out in small quantities, such as a convenience store, in a single collection, and a container in which garbage is removed The purpose is to provide a separate garbage truck that makes it easy to separate and recycle garbage.
