Description

[Detailed Description of the Invention] The present invention involves pressing used empty cans and sorting the pressed products by material, specifically into those made of magnetic materials such as steel and those made of non-magnetic materials such as aluminum. The present invention relates to a press processing device for empty cans that can be recycled.

Recently, the demand for canned beverages such as youth and coffee has been extremely high, and as a way to dispose of used empty cans, the empty cans can be pressed one by one to reduce their volume, and the pressed items can be sorted by material and collected. It is known to use structural pressing equipment.
However, conventionally known press devices of this type that have an empty can sorting mechanism built into the press section require a relatively large number of parts, making the mechanism complex and prone to breakdowns. There is a problem.

For example, in conventional equipment, a permanent magnet is attached to the press plate of a press machine, and the presses are sorted by material at the stage of pressing empty cans. It is necessary to assemble an ejecting mechanism for peeling to the push plate, which inevitably places a considerable burden on the sorting mechanism. In other words, permanent magnets are likely to be damaged due to the load required to press empty cans acting on the pushing plate, and if a failure occurs in the ejecting mechanism, the press itself must be dismantled and repaired. This is extremely disadvantageous in terms of maintenance, as it requires extensive work.

Therefore, the present invention provides an empty can in which the materials to be processed can be sorted in synchronization with the pressing operation at a stage after the empty cans have been pressed, that is, at the stairs where the pressed products are discharged onto the chute. According to the present invention, it is possible to simplify the sorting mechanism, improve the sorting function, and be significantly advantageous in terms of maintenance, and improve reliability. It is possible to construct an extremely high-quality press processing apparatus.

That is, the empty can pressing apparatus, which is a feature of the present invention, presses empty cans one by one using a receiving plate and a pushing plate that can move forward and backward with respect to the receiving plate.
In an empty can pressing device in which a chute is arranged below a drop opening for discharging pressed empty cans, the pushing plate has a pushing lever supported so as to be able to rotate only in the forward direction of the pushing plate. and rotatably supports the chute and a holding plate that can freely come into contact with the lower surface of the chute,
The chute is normally placed under the action of a spring so as to incline toward the backward direction of the push plate, and the chute is provided with an engager that faces the movement path of the push lever. A permanent magnet is attached to the free end side, and a rotary path is provided on the rotation path of the holding plate so that the holding plate can rotate in a range from a lower limit position where it is in a required tilted state to an upper limit position where it is almost horizontal. The device is provided with a stopper for regulating the device, and an embodiment thereof will be described below with reference to the accompanying drawings.

As shown in FIG.
A door plate 4 is pivotally attached to the door plate 4 to open and close the input port 3 for introducing the empty can K, and the door plate 4 guides the loaded empty can K to the press processing apparatus body 1 side. A series of guide plates 4a are provided. Further, below the press processing apparatus 1, collection containers 6 and 7 are arranged in parallel to accommodate the press processed products of the empty cans K according to their materials. In addition, 8 and 9 in the figure indicate the press processing device body 1.
It is a support stand.

The press device body 1 includes a receiving plate 11 and a supporting plate 12 that are supported in a fixed state, and a pushing plate 13 that is set so as to be able to move forward and backward relative to the receiving plate 11. The receiving plate 11 and the supporting plate 12 are arranged in a suitable manner. They are connected by a pair of connecting rods 14 at intervals. The push plate 13 is fixed to the tip of a piston rod 16 that is actuated by an actuation cylinder 15, and the piston rod 16 passes through the support plate 12.The actuation cylinder 15 is powered by a Kochi electric hydraulic pump (not shown) or the like. It is designed to be able to operate as a The press part 17 formed between the receiving plate 11 and the push plate 13 is sized to accommodate one empty can K, and its bottom part (resting part for the empty can K) 17a
A drop port 18 is formed between the front end of the support plate 11 and the receiving plate 11, and a chute 19 is provided below the drop port 18.

A push lever 21, which is allowed to rotate only in the forward direction of the push plate 13, is pivotally attached to one side of the push plate 13, and 22 is its support shaft. The back portion can freely come into contact with a stopper 23 provided on the push plate 13 side, and is normally supported in a vertical state by its own gravity.
On the other hand, the chute 19 is rotatably supported at its center by a support shaft 25 horizontally suspended on a fixed frame 24, and has an engaging element 26 projecting from the chute 19 facing onto the movement path of the push lever 21. By making the engaging element 26 freely pressable by a push lever, the chute 19 can be rotated by a predetermined angle.

In addition, a return spring 27 is hooked between the chute 19 and the fixed frame 24 to urge the chute 19 clockwise in the figure, and normally the chute 19 is directed in the direction in which the push plate 13 is retreated. It is held in a tilted position.

A holding plate 28 is provided on the lower surface of the chute 19, and the base end 28a of this holding plate 28 is connected to the chute 19.
The holding plate 28 is pivotally fixed to the support shaft 25 of the
A permanent magnet 29 is attached to the free end 28b side. Further, a regulating pin 31 is provided on one side of the holding plate 28.
An upper limit stopper 32 is provided on the movement path of the regulating pin 31 and on which the regulating pin 31 comes into contact when the holding plate 28 is in a substantially horizontal state.
In addition, the retainer plate 28 is located at a position where the retainer plate 28 is in the required inclined state when the pusher plate 13 moves in the backward direction.
Eight lower limit stoppers 33 are provided, and the rotation angle of the holding plate 28 is restricted by these two stoppers 32 and 33. According to this mechanism, at a position where the retainer plate 28 is held in a required tilted state by the lower limit stopper 33, the chute 19 is joined onto the retainer plate 28 by the return spring 27, and is held in the same tilted state. That will happen. The upper and lower limit stoppers 32 and 33 are provided protrudingly from the fixed frame 24, and the collection containers 6 and 7 mentioned above are arranged below both ends of the chute 19, and the one on the left side in the figure is made of a magnetic material. The container on the right side is used as a container for recovering pressed products made of non-magnetic material. In the figure, numerals 34 and 35 are hooks for latching the return spring 27.

According to the above configuration, the empty can accommodated in the press section 17 is pressed by the forward movement of the push plate 13 (see FIG. 2), and the pressed product K' is pressed by the backward movement of the push plate 13. At the same time, the pressed product K' falls onto the chute 19, and if the pressed product K' is made of a non-magnetic material, the pressed product K' slides on the chute 19, which is in an inclined state as shown by the solid line in FIG. It will be released into one collection container 7. The pressed product fell onto the chute 19.
If K' is made of a magnetic material, the pressed product (indicated by a solid line in the figure) as shown in Figure 3.
K' is temporarily stopped on the chute 19 by the attraction action of the permanent magnet 29. After this stop, when the empty can K is put into the press section 17 and the press operation starts, the chute 19 rotates counterclockwise in the figure due to the forward movement of the push plate 13, and at the time of this rotation, the press processing object The chute 19 and retaining plate 28 that apparently attract K' are the permanent magnets 2
The holding plate 28 is temporarily connected due to the magnetic action of the holding plate 28, and the holding plate 28 is rotated to a substantially horizontal position, separated from the chute 19, and returned to its original non-operating position. This detachment operation is performed when a regulating pin 31 provided on the retaining plate 28 hits a stopper 32 that regulates its upper limit position. On the other hand, shoot 19
holds the pressed workpiece K′ and rotates further, and the fourth
As shown in the figure, when the pressed material K' is tilted toward the receiving plate 11 side, it slides on the chute 19 and is discharged into the other collection container 6. It is possible to sort and recover the processed material K' by material.

Note that the chute 19 and the holding plate 28 are preferably formed of a non-magnetic material such as synthetic resin, and although the above embodiment has been illustrated and described for the case where the empty can K is pressed sideways, this is not applicable to the empty can K. It is also possible to press the can K in an upright position.Furthermore, if the magnetic force of the permanent magnet 29 alone is insufficient for the follow-up action of the retaining plate 28 against the chute 19, the retaining plate 28 can be pressed in an upright position. A retaining spring (not shown) that maintains the horizontal position is attached to the retaining plate 28.
and the lower limit stopper 33 side,
It is necessary to use a holding spring with a weaker force than the return spring 27 of the chute 19 described above. Therefore, when the retaining plate 28 is supported by a retaining spring, the retaining plate 28 follows the return movement of the chute 19 and returns to the non-operating position.
That is, the holding plate 28 comes into contact with the lower limit stopper 33 and returns to the tilted position.

The present invention is as described above, and is provided with a mechanism on the chute side for sorting the pressed products of empty cans by material, and the sorting mechanism can be synchronized with the press device side by a push lever provided on a push plate. This configuration makes it much easier to assemble the sorting mechanism compared to conventional devices, and the number of parts is greatly reduced, simplifying the structure and providing excellent sorting functionality. Needless to say, it is extremely advantageous in terms of maintenance and maintenance, and its practical value is extremely great.
