Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression packing apparatus used for compressing and reducing the volume of waste such as paper and waste plastic collected in a facility for recycling waste.

[0002]

2. Description of the Related Art As an example, waste plastics will be described. In recent years, waste plastics have been treated in a waste resource recycling facility in accordance with each material to promote recycling. However, the waste plastic is bulky as it is, and is difficult to handle during transportation or accumulation.
By compressing the collected waste plastic into a block shape using a compression packing device and using a band or the like to bind and pack the compressed plastic in the compressed shape, it is possible to reduce the volume and facilitate handling. Is being done.

As shown in FIGS. 7 (a), 7 (b) to 9 (a) to 9 (b) to 9 (c), an example of the above-mentioned compression packing apparatus is a rectangular cylindrical dispensing casing 1 having a gate 3 at a discharge port 2 at the tip. Inside, the tip of a dispensing cylinder 5 that accommodates a dispensing pusher plate 4 so as to be slidable along the inner surface and that is fixed forward on a support base 6 connected to the rear side of the dispensing casing 1. Is disposed at the center position of the base end of the dispensing casing 1 with a holding member 13 interposed therebetween, and the distal end of the operating rod 5a is connected to the rear side surface of the dispensing pusher plate 4 to perform dispensing. The dispensing pusher plate 4 can be pushed and pulled in the front-rear direction by the expansion and contraction operation of the dispensing cylinder 5, and further corresponds to the space between the gate 3 and the tip end surface of the dispensing pusher plate 4 retreated to the retreat limit position. Side of the dispensing casing 1 to be dispensed The one side wall portion, the distal end portion upper side inlet 8
A compression casing 7 of a rectangular cylindrical shape to which a hopper 9 is connected is arranged in the left-right direction, and the opening at the end thereof is connected and connected. A compression pusher plate 1 is provided inside the compression casing 7.
0 is slidably accommodated, and the distal end of a compression cylinder 11 (hydraulic cylinder) such as a hydraulic cylinder fixed laterally on a support base 12 installed at a base end position of the compression casing 7 is The holding member 14 is interposed at the center of the base end of the compression casing 7 and the distal end of the operating rod 11 a is connected to the compression pusher plate 10.
To allow the compression pusher plate 10 to be pushed and pulled by the expansion and contraction operation of the compression cylinder 11, and the waste plastic 15 introduced into the compression casing 7 from the hopper 9 through the introduction port 8. The compression pusher plate 10 is pushed into the dispensing casing 1, between the gate 3 and the dispensing pusher plate 4, and in the volume reduction section 20 formed by the other side wall, the ceiling wall, and the bottom surface of the dispensing casing 1. Compression molding is performed sequentially.

Further, even if the waste plastic 15 is once compressed, if the compression force is no longer applied, the waste plastic 15 greatly expands in the compression direction. The compression molded product of the waste plastic 15 discharged from the apparatus is bound at a required interval position in the extrusion direction using a band, and a binding device 16 for packing the compressed plastic while maintaining the compressed state is provided.

The gate 3 is inserted from above into the vertically extending guide grooves 17 symmetrically arranged on the left and right inner wall surfaces of the discharge port 2 of the dispensing casing 1 while engaging the left and right sides thereof, respectively. Through a connecting member 19, the distal end of an operating rod 18a of a gate cylinder 18 which is attached to the upper and lower ends of the dispensing casing 1 near the discharge port 2 and which is attached upwardly to the upper end is attached. The gate cylinders 19 can be opened and closed by synchronized expansion and contraction of the gate cylinders 19.

Therefore, when the compression packing of the waste plastic 15 is performed, first, as shown in FIGS. 7A and 7B, the waste plastic 15 in the hopper 9 is discharged through the charging port 8 into the compression casing 7. Then, as shown in FIG. 8, the compression plastic cylinder 11 pushes the compression pusher plate 10 forward to discharge the waste plastic 15 into the gate 3 and the tip end face of the discharge pusher plate 4. After being pressed into a volume reduction section 20 formed by being surrounded by the other side wall, the ceiling wall, and the bottom face of the casing 1 for compression, and then the compression pusher plate 10 is retracted by the contraction operation of the compression cylinder 11, the hopper The waste plastic 15 in 9 is thrown into the main casing 2 again through the throw-in port 8, and the pusher plate 10 for compression is moved forward as described above to be thrown in. The plastic 15 volume reduction compartment 20
, Press it into the container, and press the waste plastic 15
In the compression operation, a predetermined amount of waste plastic 15 is
The process is repeated until the data is compressed within 0.

[0007] Next, when the compression molded product of the required amount of the waste plastic 15 is formed in the volume reduction section 20, the compression cylinder 11 is stopped in the extended state as shown in FIG. After the tip end surface of 10 is arranged flush with the inner surface of one side wall of the dispensing casing 1, the gate 3 is raised by the extension operation of the gate cylinder 18 to open the discharge port 2. As shown by a two-dot chain line in FIG. 9, the dispensing cylinder 5 is extended and the dispensing pusher plate 4 is advanced to the tip of the discharge port 2 so that the waste plastic 15 formed in the volume reduction section 20 is reduced. The compression molded product is extruded from the discharge port 2 with the distal end face of the compression pusher plate 10 as a passage wall and is discharged. At this time, a required interval position in the discharge direction of the compression molded product is determined by the binding device 16. And bundling with a band, it is so as to form a bale thereof 15a of the waste plastics as a block shape.

Thereafter, the dispensing cylinder 5 is contracted to retract the dispensing pusher plate 4 to the retreat limit position, and then the gate 3 is lowered by the contracting operation of the gate cylinder 18 to close the discharge port 2. Then, the compression pusher plate 10 is retracted by the contraction operation of the compression cylinder 11 to return to the initial state as shown in FIGS. 7 (a) and 7 (b), and one cycle is completed. 8
Then, by repeating the same cycle as the above-mentioned cycle, the molding operation of the waste plastic compressed package 15a is continuously performed.

[0009]

However, in the above-mentioned conventional compression packing apparatus, the opening / closing operation of the gate 3 by the expansion / contraction operation of the gate cylinder 18 is performed in each cycle of compressing the waste plastic 15 to form the compressed packing material 15a. And the opening and closing operation of the gate 3 requires ten and several seconds each time, so that one cycle is lengthened, and there is a problem that the processing efficiency cannot be increased much. In addition, since the dispensing pusher plate 4 is advanced to the tip of the discharge port 2 in each cycle to completely discharge the compression molded product of the waste plastic 15, it is necessary for each cycle of the dispensing cylinder 15. The stroke is relatively long, which also increases the time required for one cycle. Further, since opening and closing the gate 3 requires ten and several seconds each time, the waste plastic 15 is introduced into the compression casing 7 through the inlet 8.
There is a problem that the capacity of the hopper 9 must be increased because the time during which the hopper 9 cannot be charged becomes relatively long.

Incidentally, as means for improving the processing efficiency, it is conceivable to increase the size of the hydraulic unit or the size of the apparatus, but in this case, there is a problem that the equipment cost increases.

Accordingly, the present invention is to reduce the time required for each cycle of the molding operation of a compression molded product such as waste plastic, and to improve the processing efficiency without increasing the size of the hydraulic unit or device. It is an object of the present invention to provide a compression packing device which can perform the above.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to push and pull a discharge cylinder in the direction of a discharge port inside a rectangular cylindrical discharge casing having a gate at the discharge port. The dispensing pusher plate to be slidably housed, and on one dispensing side wall portion of the dispensing casing between the retreat limit position of the dispensing pusher plate and the gate installation portion position, on the tip end upper side. A rectangular cylindrical compression casing provided with an inlet for an object to be compressed is arranged in a right angle direction, and a distal end opening is connected and connected. A compression pusher pushed and pulled by the compression cylinder inside the compression casing is provided. Board,
The waste slidably housed and the waste put into the compression casing from the input port is compressed by the pusher plate, between the gate and the tip surface of the discharge pusher plate, and the other side wall of the discharge casing. After being pressed into a reduced volume section surrounded by a ceiling wall and a bottom surface and compressed, and after opening the gate, the compressed molded product is opened by the dispensing pusher plate using the distal end surface of the compression pusher plate as a passage wall. In a compression packing device, the compressed product is discharged and discharged from a discharge port of a discharge casing, and the discharged compressed product is bound and packed by a binding device provided on a downstream side of the discharge port. On the side, a compression molded product holding cylinder having an internal shape capable of directly storing the compressed molded product compressed in the volume reduction section is integrally attached with a gate interposed therebetween, and is held in the compression molded product holding cylinder. The rear surface of the compression molded product, a configuration that can be used as walls of the compaction compartment instead of the gate.

The dispensing pusher plate is retracted in the dispensing casing and stopped at the retreat limit position, and while the discharge port is closed by the gate, the waste put in from the input port is compressed by the compression cylinder. By pushing the pusher plate forward, it is pushed into the reduced volume section of the dispensing casing and compressed, and the above-mentioned waste input and compression work is repeated so that a compression molded product of a predetermined amount of waste is reduced in the reduced volume section. When the compression pusher plate is stopped at the forward position and the gate of the discharge port is opened, the discharge pusher plate is advanced to the gate position by the discharge cylinder, and the pressure is reduced in the volume reduction section. The formed compression molded product of the waste is pushed into the compression molded product holding cylinder from the discharge port. The compression molded product is pressed against the inner surface of the compression molded product holding tube by the force to expand and the position thereof is held, so that the discharge port side of the volume reduction section is formed in the first cycle and the compression molding is performed. The compression molded product held in the product holding cylinder is closed at the rear surface in the dispensing direction. Therefore, in the next cycle, after returning the dispensing pusher plate and the compression pusher plate to the initial state position, the compression pusher plate is reduced in volume in the same manner as described above for the waste put into the main casing through the input port. When pushed to the side, the input waste can be compressed without the need for a gate at the outlet. Therefore, thereafter, in the same manner as in the above cycle, compression molding of waste is performed in the volume reduction section, and the compression molded product is
If the discharge pusher plate is sequentially pushed into the compression molded product holding cylinder by the forward operation, the gate opening / closing operation becomes unnecessary, so that the time required for opening and closing the gate is shortened, and the pushing stroke of the discharge pusher plate can be shortened. Therefore, the operating time of the dispensing cylinder is reduced.

Further, the compression molded product formed by being compressed in the volume reduction section is formed by gradually reducing the width of the compression molded product holding cylinder from the base end side toward the discharge side. When the compression molded product is pushed into the compression molded product holding cylinder, resistance can be generated in the pushing direction. Therefore, even if the force of the compression molded product to expand is weak, the compression molded product is compressed. And the discharge port side of the volume reduction section can be reliably closed by the rear surface in the discharging direction of the compression molded product.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of a compression packing apparatus according to the present invention. In the compression packing apparatus having the same structure as that shown in FIGS. One cycle of waste plastic that is compressed and formed in the volume reduction section 20 on the front side downstream of the discharge port 2 and then pushed to the gate 3 position of the discharge port 2 by the forward operation of the discharge pusher plate 4. 15 is provided with a compression molded product holding tube 21 capable of holding therein the compression molded product, and the rear surface of the compression molded product held in the compression molded product holding tube 21 in the dispensing direction is used to define the volume reduction section 20. The discharge port side is configured to be closed.

The compression molded article holding cylinder 21 is
0 is a rectangular cylinder having an internal shape substantially matching the compression molded product of the waste plastic 15 formed at 0, and the waste plastic 1 compressed and molded at the volume reduction section 20.
The compression molded product of No. 5 is pressed against the inner wall by a force to be stored and expanded as it is, so that the compression molded product can be once held inside. FIG. 7 (a) shows a position near the front of the compression molded product holding cylinder 21 on the downstream side.
(B) A binding device 16 similar to the binding device 16 shown in FIG. 9 is installed.

Other configurations are the same as those shown in FIGS. 7 (a), (b) to 9 and the same components are denoted by the same reference numerals.

When compressing and packing waste plastic 15 using the compressing and packing apparatus of the present invention, first, as shown in FIG. When the dispensing cylinder 5 is closed and the dispensing pusher plate 4 is retracted to the retreat limit position of the dispensing casing 1, the waste plastic 15 charged into the compression casing 7 from the hopper 9 through the charging port 8 is removed. As shown in FIG. 2, the compression cylinder 11 is pushed by the compression pusher plate 10 by the extension operation of the compression cylinder 11,
The tip end face of the gate 3 and the dispensing pusher plate 4 and the dispensing casing 1 are pushed into the reduced volume section 20 surrounded by the other side wall, the ceiling wall, and the bottom face and compressed. Therefore, the compression cylinder 11 is expanded and contracted, and the waste plastic 15 is put into the compression casing 7 and the compression operation is repeated. To be formed.

Next, when a compression molded product made of a predetermined amount of waste plastic 15 is formed in the volume reduction section 20, the compression cylinder 11 is stopped in an extended state as shown in FIG. The distal end surface of the pusher plate 10 is arranged so as to be flush with the inner wall surface of the dispensing casing 1 on the compression casing 7 side, and the gate 3 is raised by the extension operation of the gate cylinder 18 to open the discharge port 2. After that, as shown by a two-dot chain line in FIG. 3, the dispensing cylinder 5 is extended and the dispensing pusher plate 4 is advanced to the gate position of the discharge port 2. As a result, the compression molded product of the waste plastic 15 formed in the volume reduction section 20 is discharged through a passage surrounded by the distal end surface of the compression pusher plate 10 and the other side wall, the ceiling wall, and the bottom surface of the discharging casing 1. 2 and is pushed into the compression molded product holding cylinder 21.

In this state, as shown in FIG. 4, the dispensing cylinder 5 is retracted to move the dispensing pusher plate 4 back to the initial position, and then the compression cylinder 11 is contracted and the compression pusher plate is contracted. 10 is returned to the initial state position closer to the base end side than the charging port 8 to complete the first cycle, and at the same time, the waste plastic 15 is charged into the compression casing 7 through the charging port 8 to start the second cycle. To do it.

Next, as shown in FIG. 5, when the waste plastic 15 is put into the compression casing 7 and the compression cylinder 11 is extended to move the compression pusher plate 10 to the distal end side, the volume reduction section 20 is moved. Is closed by the rear surface in the discharging direction of the compression molded product of the waste plastic 15 formed in the first cycle and held in the compression molded product holding cylinder 21.
It is pushed between the rear surface of the compression molded product, the front surface of the discharge pusher plate 4 and the other side wall, the ceiling wall, and the floor of the discharge casing 1 and is compressed in the volume reduction section 20. The injection and compression operations of the waste plastic 15 by the expansion and contraction operation of the compression cylinder 11 are repeated to form a compression molded product of a predetermined amount of the waste plastic 15 in the volume reduction section 20.

Thereafter, similarly to the process shown in FIG. 3, after the distal end surface of the compression pusher plate 10 is arranged flush with the inner wall surface of the dispensing casing 1 on the compression casing 7 side, As shown by a two-dot chain line in FIG.
The dispensing pusher plate 4 is advanced to the gate position of the discharge port 2 by the extension operation of, and the compressed molded product of the waste plastic 15 newly formed in the volume reduction section 20 is moved by the advancing dispensing pusher plate 4. It is pushed into the compression molded product holding cylinder 21. As a result, the discharge port side of the reduced volume section 20 is closed by the rear surface in the dispensing direction of the newly pushed compression molded product, and formed in the previous cycle in the compression molded product holding cylinder 21. Since the compression molded product already held is extruded to the outside, it is bound by the binding device 16 with a band at each required interval position in the extrusion direction, and the compressed packaged product 15a of waste plastic is formed.

Thereafter, as shown in FIG. 4, the delivery pusher plate 4 is retracted to the initial position by the contraction operation of the delivery cylinder 5, and then the compression cylinder 11 is contracted and the compression pusher plate 10 is retracted. Is returned to the initial state position to end the second cycle, and at the same time, the waste plastic 15 is charged into the compression casing 7 through the charging port 8 to start the third cycle. Thereafter, by repeating the same cycle as that shown in FIGS. 4 and 5, the compressed package of waste plastic 15a is continuously formed.

As described above, after the second cycle, the discharge port side of the volume reduction section 20 is closed by the rear surface in the discharging direction of the compression molded product held in the compression molded product holding cylinder 21 to reduce the volume. Since the compression molding operation of the waste plastic 15 in the section 20 can be performed, the opening and closing operation of the gate 3 can be omitted, and the time required for opening and closing the gate 3 is eliminated, and the time required for one cycle is eliminated. Can be shortened, and the compression molded product can be compressed by the compression molded product holding cylinder 2.
In order to push the discharge pusher plate 1 into the
, The stroke of the dispensing cylinder 5 can be shortened as compared with the conventional case where the dispensing pusher plate 4 is advanced to the tip end position of the discharge port 2. Thus, the operation time of the dispensing cylinder 5 for each cycle can be shortened, and therefore, the processing efficiency can be improved and the running cost can be reduced.

Further, after the second cycle, the gate 3
Since the opening / closing operation of the hopper 9 can be omitted, the time during which the waste plastic 15 cannot be charged into the compression casing 7 can be reduced as compared with the conventional case, and the capacity of the hopper 9 can be reduced as compared with the conventional case. It becomes possible. Furthermore,
The compression molded product formed in a certain cycle is kept in a compressed state in the compression molded product holding cylinder 21 for a certain period of time until it is extruded from the compression molded product holding cylinder 21 by the compression molded product formed in the next cycle. Therefore, the finally formed compressed package 15a can be made into a stable shape with little collapse or the like.

FIG. 6 shows another embodiment of the present invention. In a compression packing apparatus having the same structure as that shown in FIGS. Instead of a rectangular cylinder having the same cross-sectional shape, a compression molded product holding cylinder 21a whose width in the left-right direction is gradually narrowed from the base end side to the distal end side.

According to the present embodiment, when a compression molded product of waste plastic 15 formed by compression in volume reduction section 20 is pushed into compression molded product holding cylinder 21a, resistance is generated in the pushing direction. Therefore, even if the force for expanding the compression molded product is weak, the compression molded product can be securely held in the compression molded product holding cylinder 21a, and the compression molded product The outlet side of the volume reduction section 20 can be reliably closed by the rear surface in the dispensing direction.

It should be noted that the present invention is not limited to only the above-described embodiment, and the compression molded product holding cylinder 2 shown in FIG.
The angle of the taper 1a may be an angle other than the angle shown in the drawing, and may be employed in a compression packing device used for compressing and packing paper as waste, and other ranges that do not depart from the gist of the present invention. It is needless to say that various changes can be made within.

[0030]

As described above, according to the compression packing apparatus of the present invention, the discharging cylinder is pushed and pulled in the direction of the discharging port by the discharging cylinder inside the rectangular cylindrical discharging casing having the gate at the discharging port. Slidably accommodates the dispensing pusher plate
In addition, a square-tube-type compression in which an inlet for an object to be compressed is provided at an upper end portion of one side wall portion on the discharge side of the discharge casing between the retreat limit position of the discharge pusher plate and the gate installation portion position. A compression pusher plate pushed and pulled by a compression cylinder is slidably housed inside the compression casing. The waste put into the compression casing is further reduced by the compression pusher plate between the gate and the distal end face of the discharge pusher plate, and the other side wall, the ceiling wall, and the bottom surface of the discharge casing. After the gate is opened, the compressed molded product is pushed out by the discharge pusher plate as a passage wall with the distal end surface of the compression pusher plate being discharged from the discharge opening of the discharge casing. In the compression packing device, which is configured to bind and pack the discharged compression-molded product by a binding device provided on the downstream side of the discharge port, in the volume reduction section, on the downstream side of the discharge port. A compression molded product holding cylinder having an internal shape capable of storing the compressed compression molded product as it is is integrally attached with the gate interposed therebetween, and a rear surface of the compression molded product held in the compression molded product holding tube is attached to the gate. In the second cycle and thereafter, the discharge port side of the reduced volume section is discharged from the compression molded article holding cylinder in the compressed molded article holding cylinder. Because it can be closed at the rear surface in the direction,
In performing compression molding of waste in the volume reduction section,
The gate opening / closing operation as conventionally required can be omitted, the time required for the gate opening / closing operation can be eliminated, and the time required for one cycle can be shortened.
Since the dispensing pusher plate may be advanced to the gate position of the discharge port, the stroke of the dispensing cylinder is shortened as compared with the conventional case where the dispensing pusher plate is advanced to the tip position of the discharge port. As a result, the operating time of the dispensing cylinder in each cycle can also be shortened, so that the processing efficiency can be improved and the running cost can be reduced.
Further, after the second cycle, the operation of opening and closing the gate is not required, and the time during which waste cannot be charged into the compression casing can be reduced as compared with the conventional case. The compression molded product formed in one cycle can be compressed in the compression molded product holding cylinder until it is extruded by the compression molded product formed in the next cycle. Since the compressed package is held for a certain period of time, it has an excellent effect that the compressed package can be made into a stable shape with little collapse and the like, and the compressed molded product holding cylinder is moved from the base end side to the discharge side. When the compression molded product formed by being compressed in the volume reduction section is pushed into the compression molded product holding cylinder, resistance is generated in the pushing direction by adopting a configuration in which the width is gradually narrowed toward Therefore, even when the force for expanding the compression molded product is weak, the compression molded product can be reliably held in the compression molded product holding cylinder, and the volume is reduced by the rear surface in the dispensing direction of the compressed molded product. This has the effect that the outlet side of the compartment can be reliably closed.
