DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to
The present invention relates to a compression packing apparatus that compresses a processed material such as a PET bottle or cardboard waste into a bale and binds the bale with a binding band.

[0002]

2. Description of the Related Art As an apparatus for compressing and packing a bale, conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 9-183414, a processed material is compressed and formed into a bale with a press board.
The tip of a binding band pulled out from above the compressor through the back of the compression chamber and forward in the discharge direction from the lower part of the bale,
A device in which a binding band delivery mechanism for connecting a middle portion of the band pushed forward from the back to the discharge side through the upper portion of the bale in the bent state is provided,
As described in JP-A-3095951, a compressor and an automatic bundling machine are arranged in series via a cylindrical passage, and a processed material is compressed and formed into a bale by a press board. There is known an apparatus that extrudes a sheet from a sheet to a binding position and binds the sheet with an automatic binding machine.

[0003]

In the former device, the delivery of the binding band is considered to be automated, but since it is not provided with a binding device, at least the cutting and connecting operations of the binding band must be performed manually. No. Also, a plurality of binding bands are used according to the size of the bale, and the reels for supplying the band are arranged at the upper part. Therefore, it takes too much time to replace and bind the reels, which is inefficient.
On the other hand, the latter device is excellent in workability because it is fully automatic,
Since a cylindrical passage is provided between the compressor and the automatic binding machine to prevent the bail from expanding, the distance to the binding position increases, and accordingly, the stroke of the extruder for pushing the bale to the binding position also increases. It must be extended, and the entire device becomes longer in the direction of bale discharge. Also, considering the manual loading, the loading port is so that the extruder and automatic binding machine do not interfere with the loading work,
It is desirable to provide it on the left or right side of the bale discharge direction, but in that case, if the frontage is widened to increase the charging efficiency, the stroke of the extruder will increase in addition to the widened frontage. The whole thing gets longer and longer. Further, the outlet door must be slid so as not to interfere with the cylindrical passage, and the sliding direction is limited to a vertical direction so as not to interfere with the band guide attached to the automatic binding machine. In addition, not only the degree of freedom in designing is limited, but also the control becomes complicated with automation.

The contact is detected by contacting the limit switch 11 attached to the main body.

A bundling machine 12 is provided adjacent to the side of the discharge port 4 of the compressor 1, and a band guide 13 attached to the bundling machine 12 is positioned at a position just before the band 4 comes out of the discharge port 4. The band 15 unreeled from the reel 14
It is lowered right below from the upper part of the right side edge, and from there, it is guided upward from the lower part on the left side through the lower side, and the band outlet 13a
It is arranged along the circumference of the discharge port so as to be caught from the head. Bale pressing guides 16 are provided above and below the discharge port 4 from the inner peripheral edge thereof to the outside.

[0008] The discharge door 4a is equipped with a double lock mechanism comprising a first lock means and a second lock means. This locking mechanism, as shown in FIGS. 5 and 6,
As the first locking means, a structure comprising a combination of a vertically slidable lock bar 17 externally attached to the right end of the discharge door 4a and locking recesses 18, 18 'provided on the main body side of the compressor 1 is provided. Also, as the second locking means, the discharge door 4
a push-up rod 19 built in to the left of
, Each of which is configured in combination with an insertion hole 20 provided in the upper part of each of them. The locking recesses 18, 18 ′ of the first locking means are provided on the upper and lower sides, respectively. The upper locking recess 18 is formed in the upper part of the discharge port 4 so as to be recessed inward and downward into a pocket shape 1.
8a is formed, and the lower locking concave portion 18 'is formed in a groove shape for guarding the lower portion of the band guide 13. Upper locking rollers 21 and 21 are attached to the lock bar 17 on both sides of a boss portion 17a protruding from the inside of the upper portion. The lower locking rollers 21 ′, 2 attached to both lower sides of the lock bar 17 are locked by fitting into
The lower side is locked by pushing 1 'into the groove-shaped lower locking recess 18'. The second locking means is
The distal end of the push-up rod 19 constantly urged upward by the spring 19a is locked by being inserted into the insertion hole 20. The insertion hole 20 is formed as a long hole having a margin in the door opening direction, and is locked in a rattling state by the second locking means alone, and when the internal pressure is received, the discharge door 4a is slightly opened. .

The two lock mechanisms are provided with one operating lever 2.
Locking or unlocking can be performed by rotating the 2. The operation lever 22 is attached to the left side of the lock bar 17 as a fulcrum, and is attached so as to be vertically rotatable along the door surface.
It is mounted at an eccentric position with respect to 2 ′ and is linked to the lock bar 17 via a plate cam 23.
The plate cam 23 and the push-up rod 19 are connected by a chain 24. The cam surface of the plate cam 23 is guided by a cam roller 25 and, together with the stopper pin 26, regulates the rotation range of the operation lever. The lock mechanism thus formed rotates the operation lever 22 approximately 45 degrees counterclockwise to push up the lock bar 17 as shown in FIG. Rollers 21 and 21 fall into dropping portion 18a
And the lower locking roller comes out of the lower locking concave portion 18 '. By further rotating the lock bar 17 by 45 degrees in the counterclockwise direction, the lock bar 17 is slightly pushed up as shown in FIG. 7B, and the push-up rod 19 is pushed from the insertion hole 20 by the pulling force of the chain 24. It can be lowered to the position where it comes out.

FIG. 8 shows a hydraulic circuit, in which both the press cylinder 5 and the push cylinder 8 are operated by pressurized oil pumped from an oil tank 28 by an oil pump 27. The operation of the press cylinder 5 can be controlled by the operation valve 29, and the operation of the extrusion cylinder 8 can be controlled by the operation of the extrusion cylinder operation valve 30. The pressure oil supply path and the return path are connected to each other by two bypass paths 33 and 34 having relief valves 31 and 32, and the relief valve 31 provided in one of the bypass paths 33 is The relief valve 32, which operates at a set pressure (low pressure) and is provided in the other bypass passage 34, is operated at a maximum pressure (high pressure). An off valve 35 is attached. Therefore, by operating the shut-off valve 35,
The upper limit of the pressure oil sent to each of the cylinders 5 and 8 can be switched in two stages.

Next, the operation of the compression packing apparatus thus formed will be described. Note that push buttons for operation described later are provided in a control box (not shown). First, by closing the discharge door 4a and pressing the reset button, the press cylinder operating valve 29 is operated to cause the press platen 6 to wait at the upper limit position. Is charged into the compression chamber 2 in a desired amount. Thereafter, when the input door 3a is closed and the compression button is pressed, the press cylinder valve 19 is operated, the press cylinder 5 is activated, and the input processed material is compressed at the set pressure by the press platen 6. When the press platen 6 reaches the lower limit position, the press plater 6 automatically returns to the upper limit position.
Again, a desired amount of the processed material is introduced. When this operation is repeated several times to increase the amount of the processed material, the compression force required to compress the processed material exceeds the set pressure, and the relief valve 31 is operated. As a result, the force becomes insufficient and the press platen 6 cannot be pushed down to the lower limit, so that the press platen 6 stops at a position where it does not reach the lower limit. When the finishing compression button is pressed, the shut-off valve 35 is closed, and a force exceeding the set pressure is applied to the press platen 6, and the processed material is further compressed, and the press plate 6 reaches the lower limit. Therefore, the pressure at which the relief valve 32 operates needs to ensure that the processed material is compressed by the press platen 6 even if the processed material is excessively filled, and that the press platen 6 has a sufficient value to reach the lower limit. Thus, the operation of compressing and forming the processed material on the bale 36 is completed.

To take out the bale 36, first, the discharge door 4a
Start by opening. When the operation 22 lever is rotated counterclockwise by about 45 degrees, the first locking means is released and the discharge door 4a is opened slightly, but the second locking means is in the locked state, so that it is not opened further. . Further, the operation lever 22
Is rotated approximately 45 degrees counterclockwise, the second locking means is released, and the discharge door 4a can be fully opened. As described above, the discharge door 4a is opened in two stages, and the force for expanding the bale 36 which has been compressed is released once the first locking means is released, thereby preventing the bale 36 from jumping out. At the same time, it prevents the discharge door 4a from opening suddenly.

After the discharge door 4a is opened, when the push button is pressed, the push cylinder valve 30 is operated to start the push cylinder 8, and the bale 36 formed by compression by the push plate 9 is pushed out by a predetermined amount. .
The pushing amount of the predetermined size can be adjusted by changing the position of the dog 10a attached to the guide rod 10. If you press the band send button here,
The band 15 is automatically sent out into the band guide 13, and the band outlet 13a is moved along the band guide 13.
Derived from When the band 15 pulled out from the band drawer 13a is applied to the upper side of the extruded bale 36 and the tip is inserted into the insertion opening of the binding machine 12, automatic binding is performed.

When the first bundling is completed, the push button is pushed again to push out the bale 36 by a predetermined size, and the above bundling operation is repeated.
6 is completely extruded from the outlet. By arranging the band guide 13 around the outlet 4 at a position just before the outlet 4 from the outlet 4, the binding machine 12 can be assembled to the side of the bale 36 in the discharge direction. As a result, the size of the device can be reduced, workability can be improved, and a highly reliable device with less causes of failure can be provided.

In the present invention, the band guide is disposed around the discharge port or at least a part around the discharge port. If the band can be led out to the opposite side through the lower side of the bale, Although it is possible to set only the lower side, it may be arranged continuously to the side surface or the upper surface as needed. It should be noted that the present invention is not limited to the embodiment, such as the control relationship and the door lock mechanism.

[0016]

According to the first aspect of the present invention, since the band guide is disposed around the discharge port or at least partially around the discharge port at a position protruding from the discharge port, the banding machine can be moved in the bale discharge direction. Can be mounted on the side, and the overall length of the device can be reduced. According to the second aspect of the present invention, by adopting a lateral opening type for the discharge door or providing the input port on the same surface as the discharge port, the door opening / closing cylinder is eliminated, resulting in a simple and less troublesome structure. In addition to this, it is possible to increase the width of the inlet so that the overall length of the apparatus is not affected.
