Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed in a garbage disposal site of a local government, a garbage collection place such as a terminal station, etc.
The present invention relates to an empty can pressing machine suitable for crushing a plurality of relatively small empty cans such as collected juice cans in a lump.

[0002]

2. Description of the Related Art Conventionally, there is an empty can pressing machine in which a large number of collected empty cans such as beverage cans and general food cans are put in a press chamber and crushed by hydraulic pressure to form blocks. The blocks discharged by the empty can press machine are inconvenient when they are loaded on a truck or the like and transported if the sizes are not uniform. Therefore, in order to facilitate handling and enable loading of a large number of blocks, it is necessary to make the discharged block size constant. When it is attempted to regulate the shape and size of the block discharged from the press chamber, the empty can is forced to be pressed in the closed press chamber, and the crushed empty can is firmly stretched in the press chamber. For this reason, the conventional empty can press machine is additionally provided with a dedicated hydraulic cylinder in order to take out the block stretched in the press chamber.
Further, there are a vertical type and a horizontal type in the empty can pressing machine depending on the pressing direction, and the horizontal type is desirable in terms of easy insertion of the empty can.

[0003]

However, in the conventional empty can press machine, in order to take out the empty can block from the press chamber, the empty cylinder block is forcibly dropped to the lower part of the empty can press machine by a hydraulic cylinder. However, since the lower part of the empty can press machine is a relatively narrow space, there was a problem that it was difficult to take out the dropped empty can block. In particular,
In a horizontal type empty can press machine having a long outer dimension, this problem is remarkable due to its structure.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide an empty can block, which is discharged from the discharge port of the press chamber and drops to the lower part of the press, to a downstream side in the transfer direction with a simple structure. It is intended to provide an empty can press machine that can be guided.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. According to a first aspect of the present invention, an empty can is placed in a press chamber and compressed by a press member, In an empty can pressing machine for dropping and collecting a compression-molded empty can block from the discharge port, the discharge port is formed on the bottom surface of the press chamber, and the discharge port is opened and closed by rotating around the axis around the discharge port. A discharge port opening / closing mechanism having a discharge port door is provided, and the discharge port opening / closing mechanism causes the discharge port door in an open state to be inclined immediately below the discharge port in order to guide the falling empty can block in the transfer direction. It is an empty can pressing machine characterized in that it can be stopped in a state.

According to a second aspect of the present invention, a shooter for guiding an empty can block that has fallen by hitting the outlet door by an inclined surface is provided downstream of the outlet door that is inclined and stopped just below the outlet in the transfer direction. The empty can press machine according to claim 1, wherein the empty can press machine is provided.

Further, a cooling fan 14 that suppresses the temperature rise of the hydraulic oil is provided on the back side of the housing 5.

The press chamber 3 having a substantially rectangular parallelepiped shape has an opening on the side face on the cylinder storage chamber 4 side among the four side faces, and the inside face of this opening side face, that is, the side face common to both side faces of the housing 5. Is gradually increasing from the upper end to the lower end to form a divergent end. That is, as shown in FIG. 2, the lower end interval of the press chamber 3 is wider than the upper end interval by slightly inclining the upper end intervals of the left and right long side walls 21, 21 of the housing 5 so as to be narrower than the lower end interval. It has a trapezoidal cross section. Then, the charging port 9 is opened close to the upper end of the side surface of the pressing force receiving wall 11 which stands substantially vertically, and the discharging port 13 is also provided.
Is also opened in accordance with the lower end of the side surface of the pressing force receiving wall 11.

The press member 7 for pressing the empty can in the press chamber 3 has a shape corresponding to the cross-sectional shape of the press chamber 3, that is, the left and right ends of the upper end of the rectangular parallelepiped press frame 7a with the rear end face opened. This is a member in which a trapezoidal plate-shaped pressing member 7b having a width smaller than the left-right width of the lower end is fixed by welding or the like, and is provided on the back side of the tip end surface to connect the tip of the rod of the hydraulic cylinder 6 for press to the connecting portion 7c The pressing cylinder 7 is pushed into the press chamber 3 by the action of the hydraulic cylinder 6 for pressing to crush the empty can. Since the pressing member 7b has a trapezoidal shape even if the pressing member 7b at the tip is trapezoidal, the pressing member 7 can be moved linearly and reciprocally with high accuracy by the sliding guide portion 22 provided on the inner surface of the housing 5.
Further, the assembling work of the sliding guide portion 22 and the press frame 7a is easy because the press frame 7a is a rectangular parallelepiped, and the so-called misalignment between the both can be easily done well.

At the center of the end of the lid body 26 on the support shaft 24 side, there is formed a recess chamber-like retreat chamber 27 that accommodates a forced-falling portion of a hooking portion, which will be described later. Further, both arm portions 25 on the rear end side of the support shaft 24
The tip of the rod 12 'of the lid hydraulic cylinder 12 is connected to the end of the shaft by a shaft 29.

Therefore, when the rod 12 'of the hydraulic cylinder 12 for the lid is extended, the arm portion 25 becomes substantially horizontal as shown by the solid line in FIGS.
Can close the inlet 9 of the press chamber 3. Then, when the charging port 9 is closed, the lower surface of the lid body 26 fitted in the charging port 9 is substantially flush with the lower surface of the ceiling plate of the press chamber 3 and functions as a part of the ceiling surface. Therefore, when the pressing member 7b of the pressing member 7 enters the pressing chamber 3, the crushed empty can is solidified into a block shape while its upper end position is regulated by the lower surface of the lid main body 26 and sufficiently pressed. Even if the empty can is crushed into a thick plate-shaped block, the empty can block does not enter the retreat chamber 27 arranged above the terminal end of the press chamber 3.

On the other hand, the rod 1 of the lid hydraulic cylinder 12
When 2'is contracted, the rear end of the arm portion 25 descends,
The arm portion 25 rotates counterclockwise in FIGS. 1 and 5 about the support shaft 24, whereby the lid body 26 can be pulled out upward from the insertion opening 9 to open the insertion opening 9. The empty can block in the press chamber 3 can be forcibly dropped by the dropping mechanism in conjunction with the opening operation of the charging port lid 10.

Next, a dropping mechanism for forcibly dropping the empty can block will be described. As shown in FIG. 5, a tubular elevating guide portion 30 is provided on the side wall side of the side facing the opening side surface of the press chamber 3, that is, outside the pressing force receiving wall 11, and a rod-shaped elevating guide portion 30 is provided inside the elevating guide portion 30. Lifting member 31
Is provided so as to be movable up and down, and an upper end of the elevating member 31 penetrates through a notch 32 formed in the pressing force receiving wall 11 in a vertically long direction. A hooking portion 33 that moves up and down is provided, and a link mechanism that converts the opening / closing operation of the loading port lid 10 into the lifting motion of the lifting member 31 and transmits the linking mechanism is provided.

The hooking portion 33 is provided on the arm portion 34 extending from the upper end of the elevating member 31 to the press chamber 3 side and penetrating the pressing force receiving wall 11, and at the tip of the arm portion 34, and the pressing surface 35 on the lower surface. And the forcible drop portion 36 formed with. And
The forced drop portion 36 fixes an angle member or the like having a substantially L-shaped cross section to the lower end of a bar-shaped portion in which the tip of the arm portion 34 is bent downward, and uses the lower surface of the horizontal portion of the angle member as the pressing surface 35, and the pressing surface 35. The width and area of 35 are enlarged. The size and shape of at least the portion of the forced drop portion 36 above the pressing surface 35 is, as shown in FIG. 5, the retractable chamber 2 formed on the lower surface of the charging port lid 10 with the charging port lid 10 closed.
Set to be stored in 7.

A link mechanism for raising and lowering the hooking portion 33 having such a structure in association with the opening / closing operation of the opening lid 10 is provided in the arm portion 25 between the shaft 12 'of the lid hydraulic cylinder 12 and the support shaft 24. One end (upper end) of the pair of link pieces 40 is connected by a shaft 41, and the other end (lower end) of both link pieces 40 is connected by a shaft 42 while sandwiching the upper part of the elevating member 31. In the present embodiment, since the elevating member 31 is located immediately below the support shaft 24 of the arm portion 25, the lower end of the link piece 40 is located below the support shaft 24 and the upper end is located outside the elevating member 31. To do.

Then, the rod 1 of the lid hydraulic cylinder 12
Since the arm portion 25 is positioned substantially horizontally when 2'is fully extended and the closing lid 10 is closed, the link piece 40 stops in the state where the lifting member 31 is raised, as shown by the solid line in FIG. , In this state, the forced drop portion 3 of the hook 33
The upper portion of the pressing surface 35 of 6 is housed in the evacuation chamber 27 of the loading port lid 10. Therefore, even if the press member 7 crushes the empty can in the press chamber 3, the crushed empty can, that is, the empty can block 43 is not caught above the pressing surface 35 of the hook 33, and the pressing surface is not pressed. The upper end surface of the crushed empty can block 43 enters below 35.
The empty can block 4 that has been crushed into a trapezoidal thick plate
3 is below the pressing surface 35, that is, the upper part of the side surface of the empty can block 43 hits the vertical part of the angle member, but since this vertical part is wider than the notch 32 of the pressing force receiving wall 11, the pressing force receiving wall is It is only pressed by 11, and no trouble occurs.

In this state, when the rod 12 'of the lid hydraulic cylinder 12 is pulled in to open the loading port lid 10, that is, when the loading port lid 10 is opened, the arm portion 25 causes the support shaft 24 to move.
5 is rotated counterclockwise in FIG.
Since the rear end is lowered, the link piece 40 moves down the elevating member 31. Therefore, the pressing surface 35 of the hook 33 extending from the upper end of the elevating member 31 into the press chamber 3 presses the upper end surface of the empty can block 43 downward. Empty can block 4
The crushed empty can is bent intricately on the upper end surface of 3 and the unevenness is severe. Even if the pressing surface 35 is pressed directly below, the pressing surface 35 and the empty can block 43 are pressed by the contact angle relationship. Surface 3
The pushing-down force of 5 does not act directly below but may act diagonally to either the left or right, but since the side surface of the press chamber 3 is inclined in the direction toward the end, it is lost as the force with which the empty can block 43 presses the side surface. The force is small, and most of the force acts as a force for dropping the empty can block 43. Therefore, even if the empty can block 43 is stretched in the press chamber 3 and firmly presses the side surface due to the springback of the crushed empty can, the empty can block 43 can be easily and surely dropped with less force than before. be able to.

Next, a discharge port opening / closing mechanism 50 for opening / closing the discharge port 13 opened on the bottom surface of the press chamber 3 will be described. As shown in FIGS. 1 and 6 to 8, the support shaft 53 is provided near the discharge port 13 opened on the bottom surface of the press chamber 3.

It is a door that opens and closes by being pivotally attached to the bracket 56 by the support shaft 53, and is formed as a rectangular plate material in accordance with the shape of the discharge port 13.

On the upper surface of the discharge port door 52, a member for buffering the shock due to the collision of the empty can block 43, or a shock resistant member (for example, an elastomer mat) capable of withstanding the shock is laminated. Is fitted into the outlet 13 when the outlet door 52 is closed.
In this way, since the impact due to the collision of the empty can block 43 is applied to the outlet door 52, two rows of the reinforcing plates 59 are provided on the back surface thereof.
Are attached and reinforced by welding or the like.

In the fan-shaped link member 55, the rotation support shaft 53 of the discharge door 52 is arranged at the center position of the arc,

Therefore, the hydraulic cylinder 51 for the outlet door
Is extended, the connection support shaft 54 of the hydraulic cylinder 51 for the outlet door moves along an arc centered on the rotation support shaft 53 (see FIG. 1).
In the direction from the right side to the lower side), and the discharge port 13 opened on the bottom surface of the press chamber 3 is closed.

On the other hand, when the outlet door hydraulic cylinder 51 is contracted, the connecting support shaft 54 of the outlet door hydraulic cylinder 51 moves on an arc centered on the rotation support shaft 53 (from the lower side in FIG. 1). By rotating in the reverse direction (to the right), the discharge port 13 opened on the bottom surface of the press chamber 3 is opened. The discharge port door 52 at the time of opening is stopped immediately below the discharge port 13 of the press chamber 3 with its upper surface inclined downward to the left in the figure, and then the empty can block 4 is dropped from the discharge port 13 to the lower part of the press machine 4.
3 is made to collide with the outlet door 52, and is slid and guided to the downstream side (left side in FIG. 1) in the transfer direction. In addition, the outlet door 5 that is open
A stop position may be regulated by providing a stopper that stops 2 in an inclined state, or the stop position may be set at the contracted end of the hydraulic cylinder 51 for the outlet door.

Further, as shown in FIGS. 1 and 3, a lock mechanism 60 is provided on the lower outside of the pressing force receiving wall 11 to hold the discharge port door 52 in the closed state. The lock mechanism 60 is fixed to the rotary shaft 61 supported along the width direction of the empty can press machine 1 and the rotary shaft 61, and rotates around the rotary shaft 61 to close the discharge door 52.

When the lock hydraulic cylinder 63 is extended, the rotary shaft 61 rotates counterclockwise in FIG. 1 via the connecting member 64 connected to the tip of the rod, and the L-shaped cylinder is fixed to this. The locking members 62, 62 are hooked on the free end side of the outlet door 52 when closed, and the closed state is held (locked). Therefore, the lock member 62 can be engaged and released with a simple structure. On the other hand, when the lock hydraulic cylinder 63 is contracted, the rotary shaft 61 is rotated counterclockwise in FIG. 1 through the connecting member 64 connected to the tip portion of the rod, and the L-shaped cylinder fixed to the rotary shaft 61 is fixed. The locking members 62, 62 are retracted from the discharge port door 52 at the time of closing to enable the opening (unlock).

In the open state, the discharge port 13
A shooter 71 for guiding the empty can block 43 from the lower part of the press machine to the outside is provided on the downstream side (the left side in FIG. 1) in the transfer direction of the discharge door 52 that is inclined and arranged immediately below. At the central portion of the shooter 71 in the longitudinal direction, the slope angle of the discharge door 52, which is obliquely arranged immediately below the discharge port 13, is continuously inclined to the lower left than the upper surface slope angle of the discharge door 52. An inclined surface 71a is formed, and a flat surface portion 71b for further reducing the sliding movement of the empty can block 43 is formed on the downstream side in the transfer direction.

With this shooter 71, the discharge port 13
Of the empty can block 43, which is collided with the outlet door 52 which is slanted immediately below, and is guided to the downstream side in the transfer direction, can be slid further outward from the lower part of the press machine and moved while decelerating. The flat portion 71b further slows down the sliding movement. In short, from the outlet door 52 to the inclined surface 71
Then, the inclination is gradually decreased in the order of a and the plane portion 71b to reduce the falling speed of the empty can block 43 and guide it in a desired direction.

Further, a conveyor device 72 for transporting the empty can block 43 to a desired place such as a stacking place is provided on the downstream side of the shooter 71 in the transfer direction.
The conveyor device 72 includes a plane portion 71b of the shooter 71.
The empty can block 43 is arranged so as to be continuous with the decelerated
Are easily guided onto the conveyor device 72. As the conveyor device 72, a belt conveyor, a roller conveyor, or the like can be adopted, and by branching during transportation, it is possible to sort into aluminum cans and steel cans.

Next, the work of crushing an empty can with the empty can pressing machine 1 having the above-described structure and the operation of each part will be briefly described. First, an empty can is loaded into the press chamber 3 through the loading port 9. In this empty can loading process, the loading port lid 10 is open, the pressing member 7 is retracted, and the discharging port door 52 is opened. It is closed, and the lock members 62, 62 of the lock mechanism 60 are locked to the outlet door 52 to maintain the closed state.

In order to put empty cans into the press chamber 3 through the charging port 9, a hopper 45 is provided as shown by the chain double-dashed line in FIG. 1 so that a large number of empty cans can be put in efficiently without spilling. You can It is preferable that the empty cans are charged until the charging port 9 of the press chamber 3 is almost full in order to improve the work efficiency and to securely contact the hooking portion 33 with the empty can block 43. . Even if it is thrown in a little beyond the input port 9, the lid main body 26 of the input port lid 10 is fitted and pushed into the input port 9 by hydraulic pressure, so that no trouble occurs.

When the empty can is sufficiently inserted into the press chamber 3, the start switch of the operation panel (not shown) is operated, whereby the lid hydraulic cylinder 12 extends the rod 12 'and the inlet lid 10 is opened. Is rotated to close the charging port 9 (closing process of charging port). By the closing operation of the insertion port lid 10, the elevating member 31 rises, and the upper part of the hook portion 33 retreats into the retreat chamber 27.

When the closing port lid 10 is fully lowered to close the closing port 9, the operation of the lid hydraulic cylinder 12 is stopped, and then the rod of the press hydraulic cylinder 6 extends to push the pressing member 7b.
And the pressing member 7b at the tip is pushed into the press chamber 3 to crush the empty can (empty can pressing step). Then, when the pressing member 7b is sufficiently advanced, the empty can inside the press chamber 3 is compressed into the thick plate-shaped empty can block 43 to be solidified. In this embodiment, the empty can is crushed until the thickness becomes about 70 mm. Therefore, the empty can block 43 that is sufficiently crushed and solidified has a trapezoidal thick plate shape that widens toward the end. Since the lock members 62, 62 are locked to the outlet door 52 and are held in the closed state, the component force of the pressing force of the pressing member 7b is applied to the outlet door 52 located on the bottom surface of the press chamber 3. Even if it works
It can firmly hold the closed state.

When the empty can pressing step is completed, the rod of the press hydraulic cylinder 6 contracts to retract the pressing member 7b, and the lock hydraulic cylinder 63 contracts to retract from the discharge door 52 and further to the discharge door. The hydraulic cylinder 51 is contracted to rotate the discharge port door 52 around the support shaft 53 to open the discharge port 13. At this time, the outlet door 52 is arranged immediately below the outlet 13 in a state of being inclined downward to the left in FIG. Even when the pressing member 7b is retracted to release the pressing force, and the discharge port 13 is opened, the empty can block 43 crushed into a thick plate is stretched to the side surface of the press chamber 3 in most cases. As it is, it does not fall and remains in the press chamber 3.

When the outlet 13 is opened, the hydraulic cylinder 12 for the lid is operated to contract the rod 12 ', thereby opening the inlet lid 10 and lowering the elevating member 31 to lower the empty can by the hook 33. The block 43 is forcibly pressed downward (block dropping step). Empty can block 4
When 3 is forcibly pressed by the hook portion 33, the empty can block 43 that has been stretched in the press chamber 3 falls easily and surely with a small force as described above, and the discharge port 1
3 is discharged to the outside.

The empty can block 43 that has fallen is discharged from the outlet 13.
In the opened state, the vehicle collides with the discharge port door 52 that is arranged directly below and slid to the downstream side (the left side in FIG. 1) in the transfer direction according to the inclination angle, and guides to the shooter 71. The empty can block 43 guided by the shooter 71 can be further slid and moved outward from the lower part of the press machine by the inclined surface 71a formed at the central portion in the longitudinal direction, and is formed on the downstream side in the transfer direction. Sliding movement is decelerated by the flat part 71b thus formed. Then, the decelerated empty can block 43 is easily guided onto the conveyer device 72, and is conveyed to a desired place such as a stacking place by the conveyer device 72 (block conveying step).

The empty can block 43 discharged and conveyed in this manner has a weight and a size that can be easily handled manually by an operator, and since it is a thick plate, it can be stacked on a pallet or the like at a collecting place or the like. You can

As described above, according to this embodiment, the empty can block 43 dropping to the lower part of the press can be guided to the downstream side in the conveying direction by the simple link mechanism, and the guide slanting plate can be separately provided. It is efficient because it does not need to be installed.

In this embodiment, the inlet 9 is formed on the top surface of the press chamber 3, one of the four side faces is opened, and the press hydraulic cylinder 6 is driven to move the press member 7 to the above-mentioned position. Although it is configured as a horizontal type empty can press machine 1 which is formed so as to be capable of advancing and retracting in the press chamber 3 from the opening side surface
The present invention is not limited to this, and the press member may be configured as a vertical empty can press machine that advances into the press chamber from above.

[0041]

As described above, the present invention has the following effects. According to the first aspect of the present invention, the discharge port door that opens and closes the discharge port formed on the bottom surface of the press chamber is stopped by the discharge port opening / closing mechanism in a state of being inclined right below the discharge port. The empty can block that drops from the discharge port of the press chamber to the lower part of the press collides with the discharge port door and can be slid and guided downstream in the transfer direction.

According to the second aspect of the invention, on the downstream side in the transfer direction of the discharge door which is inclined and arranged immediately below the discharge port,
Since a shooter for guiding the empty can block from the lower part of the press machine to the outside by an inclined surface is provided, the empty can block that is guided to the downstream side in the transfer direction by colliding with the open outlet door is further pressed. You can slide it from the bottom to the outside.

According to the third aspect of the present invention, since the inclination of the inclined surface of the shooter is set to be more gentle than the inclination angle of the discharge port door, the dropping speed of the empty can block that falls can be efficiently achieved. It is possible to guide in a desired direction while decelerating.
