[0014]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration in which a garbage container reversing device according to the present invention is provided in a refuse collection vehicle.

In FIG. 1, reference numeral 1 denotes a dust input box connected to a rear end opening of a dust storage box (not shown) mounted on a vehicle frame.

A dust loading device (not shown) is provided in the dust input box 1, and the dust put into the dust input box 1 through an input port 11 formed in the dust input box 1 is stored in the dust storage box. It is designed to be packed in boxes and loaded.

A discharge plate (not shown) slidable in the front-rear direction is disposed in the refuse input box 1. A telescopic cylinder (not shown) is connected between the discharge plate and the front part of the dust container, and the discharge plate can be reciprocated in the dust container in the front-rear direction by the expansion and contraction operation of the telescopic cylinder. In addition, the refuse loading device compresses trash when loading trash into the trash storage box and discharges the trash stored in the trash storage box.

A trash container reversing device 2 is provided at the lower edge of the input port 11 of the trash input box 1.

As shown in FIGS. 1 to 3, the trash container reversing device 2 reverses the trash container A and puts the trash stored in the trash container A into the trash input box 1 through the input port 11. A lift arm 3 attached via a bracket 31 to a lower portion of the input port 11 of the dust input box 1
And a bracket 32 having one end fixed to the lift arm 3
Arms 4 and 5 pivotally supported on the upper and lower portions of the robot, and a support base 6 on which the other ends of the link arms 4 and 5 are pivotally supported.
And a locking part 7 provided on the upper part of the support base 6 so as to be detachable from the trash container A, and a hook 8 for holding the trash container A with the locking part 7.

The lift arm 3 is connected to a lift cylinder (not shown), and is pivotally supported around an upper portion by the expansion and contraction of the lift cylinder.

As shown in FIG. 2, a rod end 42 of a rotary cylinder 41 whose base end is pivotally supported by the lift arm 3 is pivotally supported at an intermediate portion of the link arm 4. The link arm 4 is rotated by the expansion and contraction operation of the cylinder 41, and the support base 6 is raised with respect to the lift arm 3 by the link operation with the link arm 5.

As shown in FIGS. 4 and 5, the locking portion 7 is formed so as to be inserted and locked from below into a locking portion A1 formed on the upper side of the trash container A. A load cell (weight detection device) 72 attached to an attachment member 71 extending from the upper end of the load cell 72, and a cover member 73 for protecting the load cell 72.

The load cell 72 is, as is well known in the art, a transducer which converts an electric output into an electric output proportional to its size when a load is applied, and is electrically connected to a control device (not shown) by a cord 72a.

As shown in FIG. 6, the locking portions 7 configured as described above are provided on the upper end of the support base 6 in a pair on the right and left sides. It is needless to say that the locking recess A1 is formed in the upper part of the trash container A correspondingly.

The hook 8 has a base end pivotally supported on the upper part of the support base 6, and as shown in FIGS. 2 and 3, an extension rod which can extend a predetermined length to the base end of the hook 8. One end of 81 is connected. The extension rod 81 is
The extension portion 83 is inserted so as to be extendable by a predetermined length,
The other end of the extension rod 81 is pivotally supported by the other end of a bending member 84 whose one end is pivotally supported below the lift arm 3. These extension rod 81 and bending member 84
At the position where the link arm 4 is rotated by the extension of the rotary cylinder 41 and the support base 6 is raised at a predetermined height with respect to the lift arm 3, as shown in FIG. The mounting position is set so that the hook 8 is rotated by a predetermined length 81, and the tip 8a is pressed against the upper end of the trash container A by this rotating operation.

As a result, the upper portion of the trash container A is held by the support 6 while being held from above and below by the locking portions 7 and the hooks 8.

Further, a support table 6 facing the trash container A is provided.
The lower part of the rear surface is formed with a support portion 61 that supports the side surface of the trash container A when the trash container A is lifted and inverted.

Further, a load cell (weight detection device) 62 similar to the load cell 72 is provided on the support portion 61.

As shown in FIGS. 7 and 8, the load cell 62 is provided with a main body 63 provided in the support portion 61 in a state reinforced by a plurality of reinforcing members. A detection unit 64 is inserted through a through hole 61a formed in the support unit 61 and protrudes from the rear surface of the support unit 61.
And is electrically connected to a control device (not shown) by a cord 62a. Therefore, when the trash container A is held by the support 6, the side surface of the trash container A comes into contact with the detection unit 64, thereby detecting the load acting from the side surface of the trash container A.

In the measurement of the weight of the trash container A by the load cells 62 and 72, the weight of the trash container A is measured mainly by the load cell 72. When the weight of the trash container is measured by the load cell 72, a rotational moment is generated in the trash container A around the locking portion A1 due to the relationship between the shape of the trash container A and the position of the center of gravity, and the side surface of the trash container A is supported. The weight detection accuracy deteriorates due to the frictional resistance of this portion.

That is, it is ideal if the entire weight of the garbage container A is applied to the load cell 72. However, the above-described frictional resistance is applied only to a somewhat reduced load, resulting in an error corresponding to the load. If the error value is constant, it can be easily corrected, but it is not constant but increases or decreases according to the load. Therefore, the support portion 61
The load cell 62 is attached to the side surface of the device, and the weight is measured by correcting the load cell according to the measured amount. Thus, highly accurate weight measurement can be performed.

When the load cell 62 is not mounted, a synthetic resin plate for reducing frictional resistance to the support portion 61 as much as possible as a relaxation means described later, a repulsive force of a magnet,
A floating mechanism or the like by injection of compressed air will be provided.

Next, the operation of the refuse container reversing device 2 configured as described above will be described.

First, the trash container A in which trash is collected is placed facing the support base 6. Thereafter, by extending the rotation cylinder 41 and rotating the link arm 4 upward, the support base 6 is raised in combination with the operation of the link arm 5.
As a result, the locking portion 7 of the support 6 is inserted and locked into the locking recess A1 of the trash container A from below. Subsequently, when the support 6 rises, the trash container A tilts slightly downward and the trash container A is lifted with the side surface of the trash container A in contact with the support portion 61 of the support 6. When the support 6 further rises, the hook 8 pivots and presses the upper portion of the trash container A from above, and the garbage container A is clamped by the locking portion 7 so that the trash container A is securely held on the support 6. To hold.

Next, when the lift cylinder is extended and the lift arm 3 is rotated upward, the support base 6 is inverted while being lifted upward. As a result, the garbage container A held by the support 6 is also inverted, and the garbage container A faces the input port 11 of the garbage input box 1 with the upper opening facing downward, and the garbage container A
The garbage inside is put into the garbage input box 1.

At the time of the above-described dust-injection operation, the load cells 62 and 72 are lifted while the locking portion 7 of the support base 6 is inserted and locked in the locking recess A1 of the dust container A and the dust container A is lifted. , The weight of the trash container A is measured. In this weight measurement, when the hook 8 presses the upper portion of the trash container A, the pressing force acts on the trash container A, and the trash container A
In this case, the measurement is performed before the hook 8 presses the upper portion of the garbage container A because the measurement of the weight of the garbage can be inaccurate due to the trouble.

The measured weight data is input to a control device (not shown), and the net weight of the dust is calculated by subtracting the weight of the dust container A itself.

FIG. 9 shows a waste container reversing device according to the second aspect. Note that the same members as those of the trash container reversing device described in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In this trash container reversing device, a support plate 65 made of synthetic resin is provided on the support portion 61 of the support base 6 as a relaxation means so that the frictional resistance between the side surface of the trash container A and the support plate 65 is reduced. The weight of the trash container A was measured only with the load cell 72 provided on the locking portion 7 without providing the load cell on the support portion 61, as in the above-described embodiment.
Before pressing the upper part of the trash container A. In this case, unlike the above-described embodiment, only one of the load cells 72 measures the weight. Due to the structure of the trash container reversing device 2, the load cell 72 measures the weight when the trash container A is still in a substantially vertical state at an early stage when the trash container A is lifted slightly and then leaves the ground. For this reason, even if the above-mentioned relaxation means is used, the measurement can be performed with reasonable accuracy.

Further, as shown in FIG. 10, the relaxing means may be a roller 67 provided on the support portion 61 of the support base 6 via a bracket 66. In this case, when the dust container A is lifted, the side surface of the dust container A is supported by the peripheral surface of the roller 67, and the frictional resistance between the two can be reduced.

Further, the relaxing means may be a magnet as shown in FIG. By providing the magnets 68 and 69 on the side surface and the support portion of the trash container A so that they repel each other, the two can be brought into non-contact to prevent friction resistance from being generated. In this case, although the magnetic force acts on the trash container A, it does not become a significant factor that hinders the weight measurement of the trash container A, and the weight measurement with few errors can be performed.

Further, as shown in FIG.
A compressed air injection unit 91 is provided on the rear surface of the support base 6, and the inside of the support base 6 is formed as an air reservoir 92, and a hose 93 connected to an air supply source is connected to the air reservoir 92, thereby providing an air supply source. Compressed air is supplied to the air reservoir 92 via a hose 93 from the refrigeration unit 92, and the compressed air is injected from the compressed air injection unit 91 to the side surface of the trash container A. Again,
As in the case of the magnet, the side surface of the trash container A and the supporting portion 61 are in a non-contact state, and no frictional resistance is generated. The injection of compressed air to the side surface of the trash container A is a large factor that hinders weight measurement. No.

In this embodiment, the garbage container reversing device is mounted on the garbage collection vehicle. However, the garbage container reversing device is not limited to the garbage collection vehicle, and can be mounted on an appropriate trash box.

The reversing mechanism is not limited to the link mechanism.
If the garbage container has a mechanism to hold the garbage container on the support base by holding the upper part of the garbage container with the locking portion and the hook,
Any mechanism may be used.

[0046]

As described above, according to the present invention, in the trash container reversing device for holding the trash container by holding the upper portion of the trash container from above and below and inverting the trash container in this state, The dust weight can be measured at the same time as the container is turned over, and the work efficiency is good without measuring the dust weight in a separate step, and the weight of the dust is accurately measured by the weight detection device provided on the locking part and the support part. Can be measured. As described above, since the weight of the garbage input by the garbage container reversing device can be accurately measured, it is very effective when the garbage collection is charged by a method of converting the fee based on the weight of the garbage to be collected.

Further, by providing a relief means on the support portion,
The weight of the dust can be accurately measured by the weight detection device provided only in the locking portion.
