Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a used container, such as an aerosol container, for making a hole for the purpose of preventing rupture and the like for a used container which is discarded while gas remains inside. The present invention relates to a punching device.

[0002]

2. Description of the Related Art Conventionally, when disposing of an aerosol container of this kind or a used container such as a household gas cylinder, the gas is left as it is inside the container, or the attached punch or nail is used. It is perforated manually and discarded. Therefore, it is the actual situation that some of the discarded and used containers contain unperforated products.

[0003]

Therefore, when these containers are to be recovered and processed, or to be reused, those which are not perforated are selected and eliminated, and then compression treatment or heat treatment is performed. If you do not proceed with the necessary work, or if you do not proceed with the drilling process for those that have not been drilled, there is a risk of bursting. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a punching device for a used container, which is capable of continuously and mechanically punching a used container in a large amount. .

[0004]

According to the present invention, a pressing plate and a pressure receiving plate which cooperate with each other are arranged so as to face each other, and a plurality of punching tools are attached to the pressing plate or the pressure receiving plate. Alternatively, a movable plate is movably mounted via an elastic means so as to be opposed to the pressure receiving plate, and the distal end portion of the perforating tool is projected and retracted through a through hole formed in the movable plate by the operation of the pressing member. This is characterized in that the container is perforated. Further, a guide member for restricting a gap between the pressure receiving plate and the movable plate is arranged between the pressure receiving plate and the movable plate.

[0005]

In the process in which the used container is compressed between the pressing plate and the pressure receiving plate, the movable plate moves against the elastic force of the elastic means, so that the tip of the perforating tool moves. Since it projects through the through hole formed in the plate, the container is pierced by the tip of the piercing tool. Further, in the return stroke of the pressing plate, the movable plate relatively moves forward due to the elastic force of the elastic means, and as a result, the tip end portion of the perforation tool is retracted into the through hole formed in the movable plate. For,
The container falls due to gravity. In this case, if a guide member that restricts the distance between the pressure receiving plate and the movable plate is disposed between the pressure receiving plate and the movable plate, the container leaves a certain space portion and is not compressed any further. Since it is easy to perform, the punching action on the container is performed more accurately.

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, reference numeral 1 is a box forming an outer wall of the used container punching device, and the respective parts are assembled so as to be disassembled for convenience of maintenance work such as inspection. Two
Is a pressing plate, the lower part of which is rotatably supported with respect to the box body 1 via the pivotally connecting portion 3. A plurality of rod-shaped punching tools 4 having sharp tips are fixed to the pressing plate 2, and
The movable plate 5 is elastically mounted so as to be relatively movable via a supporting rod 6 and elastic means 7 such as a coil spring,
The distal end portion of the punching tool 4 can be projected and retracted through a through hole formed in the movable plate 5. FIG. 4 is an enlarged view illustrating the arrangement of the punching tools 4 when the movable plate 5 is viewed from the front.
Reference numeral 8 denotes a through hole for penetrating the punching tool 4 formed in the movable plate 5. Needless to say, the design of the perforation tool 4, the support rod 6 and the elastic means 7 can be changed appropriately in design. Then, when the pressing plate 2 swings around the pivot portion 3 by the drive mechanism, as will be described later, the pressing plate 2 is moved.
Between the pressure receiving plate 9 and the movable plate 5, which are fixed to the box body 1 side so as to oppose, the used container 10 such as an aerosol container is compressed and the perforation is performed by the perforation tool 4.

Next, the drive mechanism of the pressing plate 2 will be described. In the figure, reference numeral 11 is L below the pressing plate 2 with the pivotally connecting portion 3 interposed therebetween.
It is a drive mechanism support body that is continuously provided in a substantially horizontal direction so as to form a letter shape. A speed reducer 12 and an electric motor 13 are fixed to the upper surface of the drive mechanism support 11, and are connected via a friction belt 14 for transmission. 15 is the speed reducer 1
A rotary arm 16 is fixed to the output shaft 15 of the second output shaft, and is connected to a fixed pivot portion 18 fixed to the box body 1 side via a connecting rod 17. Then, when the power is turned on, the electric motor 13 starts to rotate, and the speed reducer 12 rotates via the friction belt 14. In the speed reducer 12, 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 15. Since the rotary arm 16 rotates with this, the connecting rod 17 swings around the fixed pivot portion 18 and the drive mechanism support 11 is pivotally attached to the pivot portion 3.
Swing around. In this case, when the drive mechanism support 11 swings upward, that is, when the pressing plate 2 is in the return stroke, the gravitational force of the speed reducer 12 and the electric motor 13 acts on the electric motor 13. On the other hand, when the drive mechanism support 11 swings downward, that is, when the pressing plate 2 is compressed and the hole is formed, the speed reducer 12 is used.
On the contrary, the gravitational force of the electric motor 13 is opposite to
Since it acts on the side that biases the downward swing of the electric motor, as a result, in addition to the driving force of the electric motor 13, the gravitational component of the speed reducer 12 and the electric motor 13 acts on the drive mechanism support body 11. Will be done. Therefore, during the compression and punching strokes of the pressing plate 2, the electric motor 13 is naturally loaded with a load necessary for compressing and punching the container 10. Since it is assisted by gravity, the load on the electric motor 13 can be reduced accordingly. In this case, the weights of the speed reducer 12 and the electric motor 13 and the lengths of their installation parts and the pivot portion 3 are adjusted so that the rotational moment around the pivot portion 3 acting on the drive mechanism support 11 is adjusted to the container 10. The load acting on the electric motor 13 can be effectively and significantly reduced by adjusting the rotation moment required for the compression and the drilling process. In this adjustment, separately using a weight,
It goes without saying that a spring for urging the pressing plate 2 for compressing and piercing the pressing plate 2 may be arranged at an appropriate portion and the elastic force thereof may be used for adjustment.

By the way, since flammable gas may remain in the used container 10 to be discarded, it is necessary to take precautionary measures against it. In this example, as the explosion-proof means, an injection port 19 for an explosion-proof gas such as carbon dioxide gas is installed above the compression and perforation work space, and if flammable gas is discharged from the container 10 by perforation, The explosion-proof gas is configured to prevent ignition. An explosion-proof motor is used as the electric motor 13, and the electric motor 13 is arranged in a substantially hermetically sealed space which is separated from the compression and punching work space by the pressure receiving plate 9, and an opening is formed in this space. It is kept slightly pressurized by a blower 21 that communicates with the outside via 20 to prevent inflow of combustible gas or the like from the compression and perforation work space side through a gap such as a lower communication portion 22. The device to do is made. In addition, when there is no possibility that residual combustible gas may be mixed in the used container 10 to be perforated by the sorting operation or the like, the pressure receiving plate is replaced with the above-mentioned supply of explosion-proof gas. If a downward air outlet 23 for air is provided at a proper position of 9, the unnecessary gas released during the perforation of the container 10 by the air flow from the outlet 23 can be transferred downward. Good.

When the used container 10 such as the aerosol container is loaded through the loading lid 24 provided on the upper part of the box body 1, the pushing plate 2 of the pressing plate 2 is advanced along the inclined plate 25. It falls between the movable plate 5 and the pressure receiving plate 9. FIG. 2 shows this state, and the pressing plate 2 is in the most retracted state. That is, the movable plate 5 is in a state of being moved most forward by the elastic force of the elastic means 7, and as a result, each of the punches 4 is in a state of being immersed in the through hole 8 of the movable plate 5. Therefore, the container 10 falls to a predetermined position between the pressure receiving plate 9 and the movable plate 5 and stops according to its size. After that,
When the pressing plate 2 rotates to enter the compression and punching stroke, the compression of the container 10 is started, and as shown in FIG. 1, the movable plate 5 is also elasticized by the elastic means 7 by the reaction force of the compression action. Move a little backwards against the force. Therefore, as a result, the tip portion of each punching tool 4 also starts to project from the surface of the movable plate 5 and starts punching laterally of the container 10. Then, when the pressing plate 2 further rotates forward, the guide members 26 fixed to both side portions on the pressure receiving plate 9 side abut on both side surfaces of the movable plate 5 to restrict the movement thereof, so that as shown in FIG. In addition, the movable plate 5 and the pressure receiving plate 9 are held at a constant distance, and the further compression action on the container 10 is stopped. As described above, the container 10 is not compressed more than a certain amount, and the movable plate 5 is regulated by the guide member 26.
Retreat relatively against the elastic force of the elastic means 7, and instead the tip of each punching tool 4 further projects, so that the container 1
The punching action for 0 is performed more accurately. In this way, when the compression and punching strokes are completed, this time, the pressing plate 2 enters the return stroke in which it rotates backward. In this process, contrary to the above, the movable plate 5 moves relatively forward by the elastic force of the elastic means 7, and as a result, the tip end of each punching tool 4 is drilled in the movable plate 5. Further, since the container 10 is immersed in the through hole 8 and comes out of the container 10, the container 10 then drops, and as shown in FIG. 1, it is accommodated outside by a guide plate 27 made of a porous material such as a wire mesh arranged below. It is discharged into the container 28 and the drilling work cycle for the used container is completed. Then, while the above working cycle is repeated, the perforating process for the container 10 is continuously performed, and during that time, the explosion-proof gas is supplied to the working space for compression and punching through the injection port 19. The flammable gas is prevented from flowing into the combustible gas by preventing the combustible gas and the like from flowing into the space of the electric motor 13 side by the blower 21 in a state where the space is slightly pressurized. In the figure, 29 is a tray for the residual liquid flowing out of the container 10.

[0010]

According to the present invention, the following effects can be obtained based on the above configuration. (1) In the compression and punching process of the container, the movable plate moves against the elastic force of the elastic means, and as a result, the tip end of the perforating tool moves through the hole formed in the movable plate. Perforate the container by projecting through,
In the return stroke of the pressing plate, the movable plate is moved forward by the elastic force of the elastic means, and as a result, the tip end of the punch is retracted into the through hole formed in the movable plate. Since the container is configured to drop due to gravity, the used container can be pierced in a large amount mechanically and smoothly. (2) The guide member provided between the pressure receiving plate and the movable plate for restricting the distance between the pressure receiving plate and the movable plate does not compress the container any more, leaving a certain space, so that the perforating tool can easily penetrate therethrough. The perforating action on the container is performed more accurately. (3) Since the structure is simple, there are few troubles.
