Here, the loading device 3 configured as described above is provided with a wire type container reversing device 5.

Hereinafter, the configuration of the wire type container reversing device 5 will be described with reference to FIGS. FIG. 2 shows a wound state of a wire in the wire type container reversing device.

A bracket 51 is fixed to the upper part of the rear surface of the slide plate 31 substantially at the center, and a first sheave 52 is supported by the bracket 51.

A bracket 53 is fixed to the inner surface of the dust box 2 above the inlet 2a.
The second sheave 54 is pivotally supported.

The second sheave 5 is attached to the bracket 53.
Along with 4, a pair of guides 55 are pivotally supported together below.

Reference numeral 56 denotes a wire wound around the first sheave 52 and the second sheave 54. After one end of the wire 56 is fixed to the bracket 51 and a middle portion is sequentially wound around the second sheave 54 and the first sheave 52,
It hangs down between the guides 55, and a hook 57 is connected to the other end.

In FIG. 1, reference numeral 6 denotes a container. The container 6 has a first engaging member 61 for engaging with the hook 57 and a lower end of the input port 2a of the dust input box 2. A second engagement member 62 that engages with the lock member 7 is provided.

The lock member 7 is rotatably provided between an open position and a securing position where the lock arm 71 is fixed in a vertical state. 62 are engaged and secured in this engaged state.

In the vicinity of the first sheave 52, the second sheave 54, and the guide 55, regulating members 8 for regulating the wire 56 from moving in the loosening direction are provided as shown in FIG. Have been.

The regulating member 8 is formed in a round bar shape.
When the slide plate 31 described later is lowered, the wire 56
Is to disperse the slack of the whole.

A total of four regulating members 8 are provided near the first sheave 52, two near the second sheave 54, and one near the guide 55.

Next, the operation of the wire type container reversing device of the refuse collection vehicle thus configured will be described.

First, the operation of the loading device 3 will be simplified.

Slide cylinder 33 and rotary cylinder 3
6, when the dust is inserted into the dust input box 2 in a state where the pushing process of the extended dust is completed, that is, in a state where the compression plate 35 is rotated forward at the uppermost position, the rotating cylinder 36 is retracted. Activate to invert the compression plate 35 backward,
When the slide cylinder 33 is retracted, the slide plate 31
Is lowered along a guide groove (not shown). As a result, the compression plate 35 descends with its front surface kept substantially horizontal,
The dust is crushed between the compression plate 35 and the arc surface 23 of the dust input box 2.

Thereafter, when the rotating cylinder 36 is extended, the compression plate 35 is rotated clockwise in FIG. The crushed dust is secondarily compressed between the compression plate 35 and the flat surface 22 of the dust input box 2.

When the compression process is completed, the slide cylinder 33 is extended to enter a dust filling process, and the compression plate 35 is raised with its front surface kept substantially vertical. The compressed dust is packed in the dust storage box 1.

Next, the operation of using the container 6 by the wire-type container reversing device 5 to put the dust in the container 6 into the dust input box 2 will be described.

First, the rotary cylinder 36 is retracted to invert the compression plate 35 backward, and the slide cylinder 33 is retracted to lower the slide plate 31.

As a result, the first sheave 52 provided on the upper portion of the slide plate 31 is also disposed at a lower position indicated by a two-dot chain line in FIG. 2, and the distance from the second sheave 54 is reduced. Therefore, the wire 56 is slackened by the amount corresponding to the shortened distance.

When the wire 56 is loosened in this way, the wire 56 is pulled out, and the hook 57 provided at the other end of the wire 56 is connected to the container 6 disposed behind the dust container 2.
(See the dashed line in FIG. 1).

At this time, the second engaging member 62 of the container 6
Are fixed to a lock member 7 provided in the trash input box 2.

In this state, the rotating cylinder 36 is extended to rotate the compression plate 35 in the clockwise direction in the figure, and then the sliding cylinder 33 is extended to move the slide plate 31 upward.

As a result, the first sheave 52 moves upward so that the distance between the first sheave 52 and the second sheave 54 becomes longer, contrary to the above-described lowering operation of the slide plate 31. Accordingly, as the distance becomes longer, the wire 56 is wound between the first sheave 52 and the second sheave 54, and the other end (the hook 57 side) of the wire 56 is drawn into the dust bin 2. In this way, the wire 56 is pulled into the refuse input box 2, whereby the container 6 with the hook 57 at the other end of the wire 56 is turned upside down around the second engagement member 62 while being inverted. Then, the refuse in the container 6 is supplied into the refuse input box 2 through the input port 2a (see FIG. 1).

When the above-described dust input operation is completed, the compression plate 35 is turned backward, and then the slide plate 31 is lowered, whereby the first sheave 52 is lowered in the same manner as described above. The slack 56 is absorbed by the weight of the container 6 with the assistance of the operator, and as a result, the container 6 returns to the original position at the initial stage of inversion.

Here, even during the above-mentioned ordinary dust loading operation without using the container 6, the first sheave 52 moves up and down with the operation of the loading device 3, so that the first sheave 52 and the second The wire 56 wound around the sheave 54 causes the aforementioned slack. Note that the hook 57 is not used during the above-described dust input operation without using the container 6.
As shown in FIG. 3, is locked by a lock 2b fixed to the periphery of the insertion port 2a.

Then, as described above, although the wire 56 causes the above-described slack, the wire 56 is restricted from being extended in the slack direction by the respective restricting members 8. That is, each regulating member 8 becomes a resistance, and the wire 56
Of the wire 56 in the loosening direction.
Is loosely dispersed, and the entire wire 56 is slackened as shown in FIG. 3, and only a part of the wire 56 is not extremely slackened.

Thus, it is possible to solve the problem that the loosened wire 56 is caught in the loading device 3 and the wire 56 is cut off or the loading device 3 is damaged.

The regulating member 8 is not limited to the round bar-shaped member shown in the present embodiment. For example, a roller or a member configured to press the roller against the wire 56 with an appropriate force may be used. Anything can be used as long as it restricts the unwinding in the slack direction.

[0042]

As described above, according to the present invention, the slackening of the wire is dispersed as a whole by restricting the extension of the wire in the slackening direction by each regulating member, and only a part of the wire is reduced. But never slack. Thus, it is possible to solve the problem that the slack wire is caught in the loading device and the wire is cut or the loading device is damaged.
