Abstract

PURPOSE:To provide a press treating device for empty cans which has a simplified construction and is improved in a screening function by providing a mechanism for selecting a material to be pressed on a chute side and turning the screening mechanism with a pressing lever which is provided to a pressing plate. CONSTITUTION:An empty can in a press section 17 is pressed by a pressing plate 13, and a treated material K' falls onto a chute 19. If the material K' is a nonmagnetic material, the material glides on the chute 19 and is released into one container. If the material K' is a magnetic material, the material is stopped temporarily on the chute 19 by the attraction effect of a permanent magnet 29. When the next pressing operation is started, the chute 10 is turned counterclockwise by the advancement of the plate 13. A holding plate 28 parts from the chute 19 upon attaining a horizontal position and a regulating pin 31 contacts with a stopper 32, thus resetting the plate to the home position. The chute 19 turns further to incline to the receiving plate 11 side, thereby discharging the material K' into the other container.

Description

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

Recently, the demand for canned beverages such as Gies 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 a press device with a structure1.However, in the conventionally known press device of this type, which has a structure in which an empty can sorting mechanism is assembled in the press section, the number of required parts is large. There are problems in that the number of devices is relatively large, the mechanism is complicated, and failures are likely to occur.

For example, in conventional equipment, a permanent magnet is attached to the press plate of the press device, and the presses are sorted by interest during the empty can pressing stage. It is necessary to assemble an ejecting mechanism to the push plate to peel off immediately after pressing, 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. Otherwise, large-scale work will be required, which will be very disadvantageous in terms of maintenance.

Therefore, the present invention provides a step after the empty can is pressed.
That is, the present invention aims to provide an empty can press processing apparatus that can perform particulate sorting of the pressed material in synchronization with the pressing operation at the stage when the pressed material is discharged onto a sheet. According to the present invention, it is possible to not only simplify the sorting mechanism, but also improve the sorting function, provide significant advantages in terms of maintenance, and construct a highly reliable 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 relative to the receiving plate, and discharges the pressed empty cans. In a press processing device for empty cans, which has a seat placed below the drop opening, the push plate is equipped with a push lever that is supported so that it can rotate only in the forward direction of the push plate. , the seat and a holding plate that can freely come into contact with the lower surface of the seat are each rotatably supported, and the seat is normally placed under the action of a spring so as to tilt in the direction of retreat of the push plate. In addition, the seat is provided with an engager that faces onto the moving path of the push lever, while a permanent magnet is attached to the free end side of the holding plate, and the holding plate is mounted on the rotating path of the holding plate. The plate is provided with a stopper that restricts the range of rotation from the lower limit position where the plate is in a required inclination state to the upper limit position where it is almost horizontal. I will explain while doing so.

The press device body 1 includes a plate 11 and a support plate 12 which are supported in a fixed state, and a push plate 3 which is set so that the plate can move forward and backward relative to the plate 11. 12 are connected by a pair of connecting rods 14 at an appropriate distance. The push plate 13 is the Inno 1 moving cylinder 15
The piston rod Hi passes through the supporting plate 12, and the actuating cylinder 15 can be operated using a known electric hydraulic pump (not shown) as a power source. It's structured. The press part 17 formed between the plate 11 and the push plate 13 is sized to accommodate one empty can K, and the front end of the bottom part (the part for placing the empty can) 17a and the press part 17 are formed between the plate 11 and the push plate 13.
A fall port 18 is formed between the
A sheet 19 is provided below 8.

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, and the push lever 2I is The rear part can freely come into contact with a stopper 23 provided on the push plate 13 side, and is normally supported by its own gravity (therefore, in a vertical state. On the other hand, the chute 19 is supported by a support shaft horizontally suspended on a fixed frame 24 The seat 19 is rotatably supported at its central portion by a lever 25, and the seat 19 is provided with a protruding retainer 26 facing onto the movement path of the push lever 21, and this engager 26 can be freely pressed by a push lever. 19 can be rotated by a predetermined angle.

In addition, a return spring 2 is provided between the seat 19 and the fixed frame 24.
7 is stopped and the eye 9 is turned upward in the open direction in the figure, and the eye 9 is normally held in an inclined state toward the backward direction of the push plate 13.

A retaining plate is provided on the lower surface of the sheet 19, and the base end 21La outside the retaining plate is pivotally fixed to the support shaft 25 of the sheet 19, and a permanent magnet 29 is attached to the free end 28b side of the retaining plate 28. Please inquire. Further: A regulating pin 31 is provided protruding from one side of the retaining plate 28, and the regulating pin 31 is placed on the moving path of the regulating pin 31 when the retaining plate 28 is almost in the water 3Y state. "Abutting" two-limit stopper 3
2, and a lower limit stopper 33 of the retainer plate 28 is provided at a position where the retainer plate 28 is inclined to a required degree in the backward direction of the pusher plate 13.
2, 33 regulates the rotation angle of the retaining plate 28.5 According to this mechanism, the seat 19 is released by the return spring at the position where the retaining plate 28 is held in the required inclined state by the lower limit stopper 33. Holding plate 2 by 27
8 and will be held in a similar inclined state. Note that the upper and lower limit stoppers 32 and 33 are provided protrudingly from the fixed frame 24, and cannot be removed from the collection containers 6 and 7 mentioned above.
They are respectively arranged below both ends of the conveyor belt 19, and the one on the left side of the drawing is used as a container for collecting pressed products made of magnetic material, and the one on the right side is used as a container for collecting pressed products made of non-magnetic material. In the figure, 3/l, 35 is a hook for fixing the return spring 27.

According to the above configuration, the empty can accommodated in the press part I7 is pressed by the forward motion of the push plate 13 (see FIG. 2), and the pressed product is pressed at the same time as the push plate 13 moves backward. --Falls on the eye 9 and touches this pressed product.
If it is made of a non-magnetic material, the pressed product will slide on the slanted surface 9 shown by the solid line in FIG. 2 and be discharged into one collection container 7. become. If K' is made of a magnetic material in the pressed workpiece that has fallen onto the root 19, then the pressed workpiece K' (indicated by a solid line in the same figure) is a permanent magnet, as shown in FIG. Due to the adsorption action of 29, it will temporarily stop above eye 9. After this stop, when the empty can K is put into the press section 17 and the press operation starts, the sheet 19 rotates counterclockwise in the figure due to the forward movement of the push plate 13, and during this rotation, the sheet 19 is rotated counterclockwise in the figure. If you miss it, the top is adsorbed 7
--The retainer plate 28 and the retainer plate 28 are temporarily connected by the magnetic action of the permanent magnet 29, and the retainer plate path is rotated to a nearly horizontal position and separated from the retainer plate 19.
Returns to original inactive position. This detachment operation is performed by the retaining plate 2.
This is done when a regulating pin 31 provided at 8 hits a stopper 32 that regulates its upper limit position. On the other hand, the sheet 19 is further rotated while holding '' on the pressed object.
As shown in FIG. 4, when the receiver is tilted toward the plate H side, the press-processed material ′ slides on the seam 9 and is discharged into the other collection container 6, and the empty space is the object of the present invention. It is possible to sort and collect the press-processed products in cans according to their interest rate.

It should be noted that the sheet 19 and the holding plate 28 are heavier if they are made of a non-magnetic material such as a 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 the case. This is possible by standing up the empty can K so that it can be pressed.
If the magnetic force of the permanent magnet 29 alone is insufficient for the following action of the retaining plate 28 on the retaining plate 28, a 4° retaining spring (not shown) is attached to the retaining plate 28 to keep the retaining plate 28 in a substantially horizontal state.
and the lower limit stopper 33 side, and it is necessary to use a retaining spring with a force weaker than that of the one return spring 27 of the above-mentioned 5-1. Therefore, when the retaining plate 28 is supported by a retaining spring, the retaining plate 28 follows the return movement of the sheet 19 and the retaining plate 28 is in the non-on/off position, that is, in the lower limit stopper 33. It will return to the position where it comes into contact and is in a tilted state.

The present invention is as described above, and a mechanism for sorting the pressed materials in empty cans by particles is provided on the root side, and the sorting mechanism is configured to be synchronized with the press device side by a push lever provided on a push plate. Because of this, it is much easier to assemble the sorting mechanism compared to conventional equipment, and the number of parts is greatly reduced, simplifying the structure and providing excellent sorting function. It is of course extremely advantageous in terms of maintenance, and its practical value is extremely great.
