Abstract

PURPOSE:To uniformize the load as a whole of an operating cycle by miniaturizing a driving mechanism and utilizing an excess force of the driving mechanism in a return stroke time of a pressing plate. CONSTITUTION:A driving mechanism swinging and driving a pressing plate 2 i5 continuously attached at a lower part of the pressing plate 2 as one body, and supported with a driving mechanism supporting body 7 extending to an almost horizontal direction by putting a pivot-attaching part 3 between them, and an end part of a rotary arm 13 attached to an output shaft 12 of the driving mechanism is connected with a fixing pivot-attaching part 15 fixed to a box body 1 side through a connecting rod 14. In such a way, because the driving mechanism of the pressing plate is supported with the driving mechanism supporting body 7 extending almost horizontally, the rotary moment is added based on the gravity of the driving mechanism by making the pivot-attaching part 3 as the fulcrum in the compression stroke time of the pressing plate, so the driving mechanism itself's outputting power can be made enough even if it is small so much.

[0003]

However, the drive mechanism of the pressing plate in the conventional empty can compressor of this type is merely fixed to the box side, and the method of installing the drive mechanism is different from that of the empty can. Regular fluctuation of load in compression work, that is, compression load is applied only during the compression stroke,
No special measures were taken to adapt to the load condition that it would not occur during the return stroke. The present invention has been made in view of the above circumstances, and provides an empty can compressor capable of reducing the output capacity required for the drive mechanism by installing the drive mechanism so as to meet the above load conditions. It is intended to be provided.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a pressing plate which is oscillated and driven around a pivotal portion arranged in the lower part, and is arranged so as to face the pressing plate. In the empty can compressor for compressing an empty can between the pressure receiving plate and the pressure receiving plate, a drive mechanism for swingingly driving the pressing plate is integrally connected to a lower portion of the pressing plate and sandwiches the pivot portion. It is supported by a drive mechanism support body extending in a substantially horizontal direction, and the end of the rotary arm attached to the output shaft on the drive mechanism side is connected to a fixed pivot portion fixed to the box side via a connecting rod. It is characterized by having done. As a specific example of the energy source of the drive mechanism, a power supply circuit combining a solar cell and a storage battery is used.

[0005]

As described above, in the present invention, the driving mechanism support body extending in the substantially horizontal direction with the pivot portion interposed therebetween is connected to the lower portion of the pressing plate, and the driving mechanism of the pressing plate is supported by this supporting body. Therefore, during the compression stroke of the pressing plate, a rotational moment based on the gravity of the drive mechanism or the like is added with the pivot portion as a fulcrum, so that the output of the drive mechanism itself can be reduced accordingly. Since the acting force required for the return stroke of the pressing plate is originally small, it suffices if the output of the drive mechanism or the like is sufficient to lift the gravity.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of a main part for explaining the operating principle of the present invention. In the figure, 1 is a box forming the outer wall of the empty can compressor, for convenience of maintenance work such as inspection,
Each part is assembled so that it can be disassembled. 2 is a pressing plate,
The lower portion is rotatably supported by the box body 1 via the pivot portion 3. The pressing plate 2 is swung about the pivot portion 3 by a drive mechanism to be described later, and the pressing plate 2 is inserted between the pressure receiving plate 4 facing the pressing plate 2 and fixed to the box body 1 side. The empty cans charged from 5 are compressed. The empty can thus compressed is separated into a steel can and an aluminum can via a separating mechanism (not shown) located below the gap between the pressing plate 2 and the pressure receiving plate 4, and is dropped into the processing can accommodating portion. In this embodiment, a step 6 is formed in the middle of the pressing plate 2, and two steps of compression processing are performed above and below the step 6.

Next, the drive mechanism for the pressing plate 2, which is a feature of the present invention, will be described. In the figure, reference numeral 7 denotes a drive mechanism support body which is continuously provided in a lower portion of the pressing plate 2 in a substantially horizontal direction with the pivotally connecting portion 3 interposed therebetween. The speed reducer 8 is fixed to the upper surface of the drive mechanism support 7 and the electric motor 9 is fixed to the lower surface thereof, and these constitute the drive mechanism in this embodiment. An output shaft 10 of the electric motor 9 is connected to the speed reducer 8 via a friction belt 11 for transmission. Reference numeral 12 denotes an output shaft of the speed reducer 8. A rotary arm 13 is fixed to the output shaft 12 and is connected to a fixed pivotal attachment portion 15 fixed to the box body 1 side via a connecting rod 14. .

When the power is turned on, the electric motor 9 starts to rotate, and the speed reducer 8 is passed through the friction belt 11.
Rotates. In the speed reducer 8, the rotation speed is reduced to a predetermined speed by an internal gear means or the like, and the speed is output from the output shaft 12. As a result, the rotary arm 13 rotates, so that the connecting rod 14 swings about the fixed pivot portion 15, and accordingly, the drive mechanism support 7 also swings about the pivot portion 3.
In this case, when the drive mechanism support 7 swings upward, that is, during the return stroke of the pressing plate 2, the electric motor 9 mainly includes the speed reducer 8 and the electric motor 9 which are main elements of weight. Gravity will act. On the other hand, when the drive mechanism support 7 swings downward, that is, during the compression stroke of the pressing plate 2, the gravitational components of the speed reducer 8 and the electric motor 9 conversely move downward to the drive mechanism support 7. An electric motor 9 acting on the connecting rod 14 via the speed reducer 8 acts on the drive mechanism support 7 because it acts on the side that biases the swing.
In addition to the reaction force based on the driving force of, the gravitational component of the speed reducer 8 and the electric motor 9 acts. Therefore, during the compression stroke of the pressing plate 2, the electric motor 9
On the other hand, a load for compressing the empty can is applied on the one hand, and at the same time, the load on the electric motor 9 can be reduced by that much because it is assisted by the gravity of the speed reducer 8 and the motor 9 on the other hand. In this case, the weights of the speed reducer 8 and the electric motor 9 and the positions where they are installed and the length of the pivot portion 3 are adjusted so that the rotational moment around the pivot portion 3 acting on the drive mechanism support 7 can be adjusted by the empty can. If the rotational moment required for the compression process is adjusted, the load acting on the electric motor 9 during the compression stroke can be effectively and significantly reduced. In this adjustment, a weight may be separately used, or a spring for urging the pressing plate 2 toward the compression stroke side may be provided at an appropriate portion to adjust the elasticity by using the elastic force. It goes without saying that you will get it.

As described above, according to the present invention, the load acting on the drive mechanism when the empty can is compressed can be greatly reduced, so that the drive mechanism can be downsized and its power consumption can be reduced. It is extremely effective when providing an empty can compressor using a power supply circuit composed of a combination of The present invention can be adopted without distinction between large capacity and small capacity, and is not limited to the mode of loading empty cans,
It goes without saying that it can be applied to various types of empty can compressors.

[0010]

According to the present invention, the following effects can be obtained based on the above configuration. (1) The load acting on the drive mechanism during the compression stroke of the pressing plate can be significantly reduced. Therefore, the drive mechanism can be downsized. (2) Moreover, since the reduction of the load is performed by utilizing the remaining capacity of the drive mechanism during the return stroke of the pressing plate, it is possible to reduce the variation of the load in the entire operation cycle and achieve the averaging. (3) Since power consumption can be reduced, it is effective when a power supply circuit combining a solar cell and a storage battery is used as a power supply for a drive mechanism, and it is easy to install an empty can compressor in a place without a power supply facility. Become. (4) Since the structure is simple, there are few troubles.
