Description

[Detailed description of the invention] [Industrial application field]

In the present invention, used empty cans are pressed one by one, and the pressed products can be sorted by material, specifically those made of magnetic materials such as steel, and those made of non-magnetic materials such as aluminum, and then collected. The present invention relates to an empty can press processing apparatus.

[Conventional technology]

Recently, there has been an extremely high demand for canned beverages such as youth and coffee, and the way to dispose of used empty cans is to press the empty cans one by one to reduce their volume, and then sort the pressed products by material. It is known to use a press device with a retrievable structure. However, in the conventional press device for this type of empty can, a permanent magnet is embedded in the press plate of the press device, and if the pressed empty can is made of a non-magnetic material,
This pressed product falls from the press section as soon as the push plate starts its backward movement. On the other hand, if the pressed empty can is made of magnetic material, this pressed product made of magnetic material is temporarily moved to the push plate. There is a structure in which the press plate is attracted and moved back in the press section together with the press plate, and then dropped by an ejecting mechanism at a position different from that of the non-magnetic pressed product.

[Problems to be solved by the invention]

The conventional empty can pressing device described above, which is configured to sort the pressed items of empty cans by material, requires a large number of parts, making the mechanism complicated, and also requires the ejection mechanism to be assembled to the pushing plate. Therefore, it is unavoidable that a considerable burden is placed on the sorting mechanism, and there is a problem that failures are likely to occur. In other words, the permanent magnet is likely to be damaged due to the load required for pressing empty cans acting on the pushing plate, and if a failure occurs in the ejecting mechanism, the pressing device itself must be dismantled and repaired. This is extremely disadvantageous in terms of maintenance, as it requires extensive work.

[Means to solve the problem]

Therefore, in the present invention, after the empty cans are pressed, in other words, at the stage when the pressed products have fallen from the press section and are released onto the chute, the pressing work is performed to sort the pressed products by material. The above-mentioned problems are completely solved by configuring the press processing apparatus so that the press processing can be carried out in synchronization. Therefore, the object of the present invention is to press empty cans one by one using a receiving plate of a press device body and a pushing plate that can move forward and backward with respect to the receiving plate, and to create a drop opening for discharging the pressed empty cans. In an empty can press processing apparatus in which a chute is arranged below, the chute and a holder that can freely come into contact with the lower surface of the chute are each rotatably supported, and the chute is configured to:
The push plate is configured to transmit rotation so that it can maintain an inclined state in which it faces in the backward direction when the push plate is in the retracted position, and in the forward direction when the push plate is in the forward position. On the other hand, a permanent magnet is attached to the free end side of the holder, and a lower limit position is provided on the rotation path of the holder at which the holder is in an inclined state corresponding to the chute. This is achieved by an empty can press processing device that is provided with a stopper that restricts the range of rotation from 1 to an upper limit position where the container is in a substantially horizontal state.

【Example】

Embodiments of the present invention 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 has a guide for guiding the loaded empty can K to the press device body 1 side. A series of plates 4a are provided. Further, below the press device body 1, collection containers 6 and 7 are arranged in parallel to accommodate the pressed products of the empty cans K according to their materials. Note that reference numerals 8 and 9 in the figure are support stands for the press device body 1. 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 known 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 pushing plate 13 is sized to accommodate one empty can K lying on its side, and the front end of the bottom part (resting part for empty can K) 17a and the receiving plate A drop port 18 is formed between the drop port 11 and a chute 19 below the drop port 18. A downward L-shaped push arm 21 is fixed to the lower part of at least one side of the push plate 13, and the lower part of this push arm 21 has a bifurcated engagement portion 21.
It is formed in a. On the other hand, the central portion of the chute 19 is rotatably supported via a support piece 24 on a support shaft 23 that is horizontally suspended on an inverted gate-shaped fixed frame 22, and the chute 19 is engaged with the push arm 21. The connecting rod 2 is always engaged at the portion 21a.
5 is fixed. That is, the upper end side of the connecting rod 25 has a hook portion 2 bent outward at a right angle.
5a, and this hook portion 25a is the engaging portion 21.
a and rotates the chute 19 following the reciprocating movement of the push plate 13. Further, a holder 26 is disposed in contact with the lower surface of the chute 19, and the base 26a of the holder 26 is rotatably supported by the support shaft 23 of the chute 19, and its free end 26b side is is the holding body 26
A permanent magnet 27 is attached flush with the top surface of the magnet. Further, on the rotation path of the holder 26, the holder 2
A stopper 28 having an L-shaped cross section is provided to regulate the rotation angle of the pusher plate 6. This stopper 28 is fixed on the bottom part 22a of the fixed frame 22, and its lower edge is arranged so that the chute 19 is directed toward the retracted position of the pusher plate 13. As a lower limit stopper part 28a that receives the holder 26 at the lower limit position where it is in a tilted state corresponding to the previously tilted posture, and as an upper limit stopper part 28b that receives the holder 26 at the upper limit position where the upper edge is in a substantially horizontal state. It is functional. The collection containers 6 and 7 mentioned above are arranged below both ends of the chute 19, and the collection container 6 on the left side of the figure is used to store pressed materials made of magnetic materials, and the collection container 7 on the right side is used to store pressed materials made from non-magnetic materials. It is used as a container to collect each processed material. In the figure, 29 is a shaft hole drilled in the fixed frame 22, and 31 is an insertion hole for a fixing bolt of the fixed frame 22. 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. Therefore, it falls from the drop opening 18 onto the chute 19. If the pressed product K′ that fell onto the chute 19 is made of non-magnetic material,
As shown in FIG. 3, the pressed product K' slides on the chute 19, which is tilted downward, in the direction of retreat of the push plate 13, and is discharged into one of the collection containers 7. However, shoot 19
If the pressed object K' that has fallen onto the top is made of a magnetic material, this pressed object K' is attached to the permanent magnet 27.
It is temporarily stopped on the chute 19 by the adsorption action of the chute 19 (in this case, the chute 19 and the holding plate 26 are joined). During this stop, when an empty can K is put into the press section 17 and the press operation starts, the forward movement of the push plate 13 causes the chute 19 to rotate counterclockwise in the figure, and during this rotation, the press The chute 19 and the holder 26, which are apparently adsorbed with the workpiece K', are temporarily connected by the permanent magnet 27, and the holder 26 rotates to a nearly horizontal position and is removed from the chute 19. It moves away and returns to its original inactive position. This detachment operation is performed when the lower surface of the holder 26 hits the upper limit stopper portion 28b of the stopper 28. On the other hand, the chute 19 further rotates while holding the pressed workpiece K', and when it tilts in the forward direction of the pushing plate 13 and slopes down as shown in FIG. The objects K' are slid and discharged into the other collection container 6, and the objective of the present invention, which is to collect the pressed objects K' of the empty cans K by material, can be achieved. In addition, if the magnetic force of the permanent magnet 27 is insufficient for the follow-up action of the holder 26 on the chute 19, or if the chute 19 rotates toward the holder 26 due to the backward movement of the push plate 13 and becomes horizontal. When the holding body 26 is brought into contact with the holding body 26 at a position, a relatively weak holding spring capable of holding the holding body 26 in a horizontal state is applied to the holding body 26. Also,
It is preferable to use a chute 19 formed in the shape of a drainboard, and the rotation transmission member constituted by the push arm 21 and the connecting rod 25 may be replaced with another rotation transmission member such as a rack and pinion. Furthermore, in this embodiment, the press processing device that presses the empty cans K by lying them down has been described, but this presses the empty cans K by standing them up by changing the design of the input port 3 and the press section 17. It can also be implemented as follows.

【Effect of the invention】

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 according to material, and the sorting mechanism is different from the press apparatus body side by a rotating mechanism provided between the push plate and the chute. Since we adopted a structure that operates in constant synchronization via a transmission member, it can withstand long-term use without putting undue stress on the operating members, and unlike conventional devices, it is extremely easy to assemble. This is extremely advantageous in terms of maintenance and maintenance, the number of parts can be greatly reduced and the structure can be simplified, and the chute can be rotated at both reversal positions to prevent press processing. Since it is made possible to release each of these, the sorting function is reliably performed in synchronization with the press operation, which has the effect of providing an extremely reliable press processing apparatus.
