DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin container used for a garbage truck and, more particularly, to a garbage collection and garbage collection system.
The present invention relates to a synthetic resin container as an attachment for a collection vehicle such as a packer truck used for transportation.

[0002]

2. Description of the Related Art At present, most of the collection and transportation of municipal solid waste is carried out by a push-type collection vehicle in which a packing box rotates, a collection vehicle equipped with a container tilting device, a dump truck, and the like. Among these vehicles, collection vehicles equipped with a container tilting device are used in apartment houses, cafeterias that output large amounts of waste, and the like.
It belongs to large vehicles of t or more. In this collection vehicle, garbage is put into a dedicated container, the container is tilted by a collection vehicle equipped with a container tilting device, and refuse is transferred to the collection vehicle. Therefore, there is no state where the refuse is exposed, and the worker does not touch the refuse, so that extremely sanitary handling can be performed.

[0003] The container tilting device attached to this collection vehicle is characterized in that the weight of the garbage stored in the container is large (for example, 100 kg), and that if the container falls off during the tilting operation, it is dangerous. Various tilting devices have been proposed in order to satisfy conditions such as that sewage in garbage does not leak during the tilting operation. Therefore, the containers themselves have different structures to match these tilting devices.

[0004] However, the common feature of any container is that it is formed of a deep bottom box having a rectangular opening at the upper end, a hinged lid at the upper end, a caster at the bottom, and , A handle is provided on the upper end side for the operator to push and pull.

On the other hand, if different types of containers for different types of container tilting devices are classified, for example, regarding the tilting center, a) The tilting center is set at the flange at the peripheral edge of the upper end opening (for example, JP-A-60-2
58003), b) A container is fixed in a basket-shaped frame, and the upper part of the frame is tilted center (for example, JP-B-55-11562, JP-B-57-16042, C) A pair of tilting pivots projecting from both sides of the peripheral edge of the upper end opening (for example, see Japanese Patent Laid-Open No. 4-140201).
Gazette, Japanese Unexamined Patent Publication No. Hei 4-140202,
No. 25763), d) a container having a tilting pivot attached above the front of the container (for example, Japanese Utility Model Application Laid-Open No. 63-13 / 1988).
No. 0406).

[0006] By the way, containers classified into these are mainly made of steel plate, but some are made of FRP or those made by injection molding (Japanese Patent Laid-Open No. 4-140202). Reference).

[0007]

However, a steel plate container has a problem of rust and the like as if a tin bucket was swept over a polybucket. An FRP container or an injection molded container had only a caster and a pivot. However, there is a problem that the cost is higher than that of the ordinary large-sized waste plastic container, which is disadvantageous for the end user.

In order to solve such a problem, it is conceivable to blow-mold a container to make it inexpensive. However, if the container is a blow-molded product, the container storing the heavy waste as described above is often mechanically tilted by a collection truck, and the tilting center portion is particularly thick. It was found that there was a risk that the device could be damaged.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and its gist is to provide a deep-bottom box having an upper end opened in a rectangular shape. A container having a hinged lid at its bottom and a caster at the bottom, and a vertically wide groove (10) recessed in the front of the container body (2).
In a synthetic resin container used for a garbage truck in which a pivot (12) having a tilting center of the container is disposed substantially at the center of the container body (2) in the vertical direction, a wide groove (10) of the container body (2) is provided. The inserts (11) located on both sides of the shaft are configured to support both ends of the pivot (12). The inserts (11) are formed by injection molding, and the protrusions (17) and the protrusions project outward and to the left and right. Department (1
5) are provided in parallel, and the insert body (11) is mounted on the inner surface of the blow mold so as to be positioned outside the front surface of the container body (2). Is blow molded into a container body (2), and the container body (2) is provided with the insert body (11).
The projecting portion (15) is brought into close contact with the non-recessed portion on the front surface of the container body (2) so as to be in a synthetic resin container used for a garbage truck.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings. 1 is a cross-sectional view of a main part of an embodiment of the present invention (a cross-sectional view taken along the arrow A in FIG. 4), FIG. 2 is a main part view of FIG. 1, and FIG.
4 is a side view taken along arrow B, FIG. 4 is an overall side view of the embodiment, FIG. 5 is a side view taken along arrow C in FIG. 4, FIG. 6 is a plan view taken along arrow D in FIG. 4, and FIG. It is a side view.

The present embodiment is suitable for a container used as an attachment for a municipal waste collection / transportation truck equipped with a container tilting device, and is blow-molded with polyethylene as a parison and has a capacity of 130 to 200 liters. .

First, the entire container 1 will be schematically described.
4 to 7, the main body 2 has an upper end of 500 ^mm × 45.
It is opened in a rectangular shape of 0 ^mm , and is formed of a deep bottom box having a depth of 950 ^mm . On the upper end side of the rear surface 2a of the main body 2, a handle bar 3 that is gripped and pushed and pulled by an operator is provided horizontally. A lid 4 is provided on the handle bar 3 in a hinged manner.

A caster 5 composed of two wheels is provided at a lower portion of the rear surface of the main body 2. That is, this rear surface 2
In a, a pair of bearing portions 6 and 6 are formed downward in a fork shape, and a bag-like fitting portion 6a which is slightly opened is formed in these bearing portions 6. The caster shaft 7 is pushed into the bag-like fitting portion 6a from its opening by utilizing resin deformation and fitted. Between the caster shaft 7 and the base of the fork portion, a gap 8 for inserting the toes is formed. The bottom of the main body 2 is formed in a substantially flat shape except for the mounting portion of the caster 5, and forms a landing surface 9. Therefore, the container 1 is stably erected by the landing surface 9 and the casters 5. When the operator pushes and pulls the container 1, the operator puts the tip of the operator into the gap 8, slightly tilts the container 1 backward with the handle bar 3, and moves the container 1.

Here, a wide groove 10 is recessed in the front surface 2b of the main body 2. Over this wide groove 10,
A tilting pivot 12 is provided via an insert 11 made of an inverted trapezoidal plate. That is, in FIGS. 1 to 3, the pivot 12 is formed of a steel pipe having a diameter of about 36 ^mm , and both ends thereof are closed with plugs 13. The pivot 12 is connected to a pair of circular bosses 1 in the insert body 11 described below.
4 are supported at both ends.

The insert body 11 is a plate having a thickness of t = 4 ^mm and formed in an inverted trapezoidal shape of approximately 300 ^mm × 160 ^{mm in} a plan view. The insert 11 is made by injection molding polyethylene in advance. The insert body 11 is formed as a connecting plate by forming a concave portion 10a so as to match the wide groove 10.
The pair of bosses 14 are formed on both sides of the concave portion 10a so as to face each other. That is, the boss 14 (the pivot support portion) is located substantially at the center in the vertical direction on both banks of the wide groove (10). Flange plates (also referred to as protruding portions) 15 extend outwardly (left and right outwards) from the cylindrical outer peripheral ends of these bosses 14, respectively. An inwardly tapered portion 16 is formed at the outer end of the flange plate 15. This tapered portion 16
This prevents the insert body 11 from peeling off from the main body 2 when a parison described later is brought into close contact. The flange plate 15 is flush with a part of the front surface of the container body 11 which is not the wide groove 10.

On the outer surface of the recess 10a, a plurality of locking ridges (also referred to as protrusions) 1 are formed in parallel with the flange plate 15.
7, 17,... Are provided. When the insert 11 is integrated with the main body parison by the ridges 17, the insert 11 is separated from the main body 2 when the insert 12 is supported horizontally by the pair of bosses 14 and supports the pivot 12 receiving the tilting rotational force. We do not come off. And
The height of the ridges 17 is 6 ^mm , and three ridges 17 are provided at intervals of about 20 ^mm .

Next, the operation of this embodiment will be described. A steel pipe pivot 12 is rotatably inserted into an insert body 11 separately injection-molded. Then, the insert 1 with the pivot 12
1 is mounted on the inner surface side of a blow molding die (not shown).
Therefore, a plasticized parison (not shown) is added to this mold.
And the main body 2 can be formed by blow molding. At that time, the parison is engaged with the flange plate 1 of the insert body 11.
5. Since it is in close contact with the outer surface of the concave portion 10a, the plug 13 of the pivot 12, etc., the insert body 11 and the main body 2 can be strongly integrated, and can be favorably supported even if the pivot 12 acts on the pivot. In particular, the parison reaches the triangular space between the arc surface outside the cylindrical body (outside the container) of the boss 14 and the front surface 2a of the main body 2, and the insert body 11 and the main body 2 can be strongly integrated.

[0018]

According to the present invention, 1) a wide groove (10) provided on the front surface of the container body (2).
Since the pivots (12), which are the tilting centers of the containers containing heavy refuse, are supported by the inserts (11) located on both sides of the container, the external force is the least in the thin molded blow molded container. The pivotal support portion that acts severely can be made thick to have strength. 2) Left and right outwardly projecting portions (1
5) and the protrusion (17) are provided in parallel, and the protrusion (15) is flush with the non-recess on the front surface of the container body (2). During this time, the parison wraps around, and the insert body (11) and the parison are further brought into close contact with each other. 3) Since the container body (2) is blow-molded with the insert body (11) on the outside, even if the pivot (12) bends when the container is tilted, wastewater in the garbage does not leak from the pivot support portion even if the pivot is bent. . 4) Left and right outwardly projecting portions (1) of the insert body (11).
Since 5) is flush with the non-recessed portion on the front surface of the container body (2), the tilting motion can be smoothly performed without being obstructed by the container tilting device provided in the collection truck.
