Description

  The present invention relates to a technique for maintaining a volume reduction state of a processing object made of a material to be restored after compression, such as a plastic bottle or a plastic container, by temporarily fixing.

  In recent years, with the increase in the amount of waste generated, it has become important for environmental conservation to recycle the waste. In addition, companies that discharge a predetermined amount of material waste have established certain environmental standards. For this reason, companies that discharge a large amount of material waste such as empty cans and cut pieces of paper have been subject to disposal with a high compression ratio. However, user needs have not been sufficiently satisfied due to factors such as the high price of the main body of the device for compressing them, the large main body, the small processing capacity, and the inability to fix after compression.

Moreover, as a conventional material waste compressor, it is a press machine using hydraulic pressure or the like, and material waste to be compressed can be processed only in batches. The present applicant has discovered Japanese Patent Application Laid-Open No. 2002-301594 “Can Crusher” in view of the above problems (for example, see Patent Document 1). This is an apparatus that can reliably and continuously process material wastes such as empty cans that are bulky.
JP 2002-301594 A

  However, there are the following problems that cannot be solved by the above idea. First, in recent years, plastic bottles that have been widely used in place of metal cans and the like have a restoring force and may easily be restored after compression. For this reason, it was necessary to bind and fix with a wire after compression. In this method, the wire is removed again at the time of recycling, which is troublesome and troublesome.

  Secondly, the PET bottle body, the cap and the label are usually made of different materials. For example, the main body portion is made of polyethylene terephthalate, the cap is made of polypropylene, and the label is made of polystyrene or the like. For this reason, it is necessary to separate these again at the time of recycling.

  Thirdly, there is a problem of residual liquid that occurs when left over. This is because the cap of the plastic bottle is closed, and it is very often discarded when the contents are contained. When compression is performed in this state, the contents are scattered around and the compression device becomes dirty. Further, when compression is performed with the cap attached, there is a possibility that a plosive sound is generated.

  Therefore, a problem to be solved by the present invention is to maintain the shape at the time of compression when compressing resource garbage having a restoring force. Another object of the present invention is to provide a technology that makes it possible to easily separate resource wastes of different materials and can greatly reduce labor during recycling.

Therefore, the plug portion is cut off from the main body by the plug portion cutting mechanism.

It was possible to provide a volume reduction device that maintains the shape at the time of compression when compressing resource garbage having a restoring force.
In addition, it has been possible to provide a volume reduction device that can easily separate resource wastes of different materials and can greatly reduce labor during recycling.

  Hereinafter, the present invention will be described in more detail based on embodiments and drawings. The drawings used here are FIGS. 1 to 9.

  FIG. 1 is a front sectional view showing a volume reducing device 1, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a plan view showing an inlet. The volume reduction device 1 is a device for preventing a plastic bottle 70 (processing object) having a restoring force from being restored after compression, and includes an insertion port 5 for inserting the plastic bottle 70, a frame 10, and the like. A pressing mechanism 20 disposed in the frame body 10, a punching mechanism 30 disposed on the traveling direction side of the pressing mechanism 20, and a driving source for operating the pressing mechanism 20 and the punching mechanism 30. A drive motor 40 is provided.

(Inlet / Frame)
The insertion port 5 is disposed in the upper part of the frame body 10 and is formed in a substantially square shape in vertical and horizontal directions in plan view. Further, the four inner peripheral surfaces 5 a, 5 b, 5 c, 5 d are arranged so as to incline toward the insertion port 5, and the opening portion of the pressing mechanism 20 is arranged immediately below the insertion port 5. That is, the PET bottle 70 has a structure in which the PET bottle 70 is always inserted in the vertical direction with respect to the insertion port 5 and sent to the pressing mechanism 20. The frame body 10 is formed of a substantially rectangular rectangular tube and is composed of four side plates 10a, 10b, 10c, and 10d. The lower part of the frame 10 is erected on a floor via a support base (not shown).

(Pressing mechanism)
The pressing mechanism 20 has a pair of pressing belts 21 and 22 arranged to face each other. The pressing belts 21 and 22 are disposed in the frame 10 in the vertical direction and the pressing surfaces 21 a and 22 a are opposed to each other. The pressing belts 21 and 22 are endless belts that are movable in opposite directions, and are provided with upper and lower sprockets 23 and 24 that are wound around both upper and lower ends, respectively. The sprockets 23 and 24 have rotating shafts 23a, 23b, 24a, and 24b, and these are all supported by the side plates 10a and 10d of the frame 10.

Both sides of the rotating shafts 24a, 24b located on the lower side protrude outward from the side plates 10a, 10d, a connecting member 25 is attached to the protruding end, and a rotation transmission wheel 26 is attached to the other end. ing. The rotation transmission wheel 26 is connected to the rotation shaft 24a, the drive wheel 41 of the drive motor 40, and the chain 42. For this reason, the driving force of the drive motor 40 is transmitted to the one pressing belt 21 through the chain 42, and then transmitted to the other pressing belt 22 through the rotation transmission wheel 26.
In addition, the pressing belt 21 is arranged so as to be inclined so that the opening 5 side is wide open in the normal state, and the opposite side which is the outlet of the PET bottle 70 is narrow. Accordingly, the pressing belts 21 and 22 are easy to grip the plastic bottle 70, and the plastic bottle 70 is compressed by moving in the traveling direction.
Since it is an endless belt type pressing mechanism, it is excellent in continuous processing.

(Punching mechanism)
By the way, when the PET bottle 70 is not charged with the cap side facing downward as shown in FIG. 1, the air in the PET bottle 70 is ruptured in the process of being compressed by the pressing mechanism 20, and the cap pops out from the charging port 5. There was a risk of it.
Therefore, although not shown, a needle as a punching hole mechanism is provided in the vicinity of the insertion port 5. This needle is for making an air hole in the main body portion of the plastic bottle 70. When the plastic bottle 70 is inserted into the insertion port 5, the air hole is opened by the needle of the punching hole mechanism, thereby preventing the cap from popping out and bursting.

The pressing belts 21 and 22 are provided with a carrier bar 27. The carrier bar 27 is provided to prevent the PET bottle 70 from slipping when the PET bottle 70 is pulled to the perforating mechanism 30 side by the pressing belts 21 and 22.
When a steel or aluminum can is crushed by the pressing mechanism, the can is often painted. As the coating adheres, the belt may slip, and the carrier bar 27 prevents such slip.

(Drilling mechanism)
The punching mechanism 30 includes a fixing member 31 that fixes one end of the PET bottle 70, a punching member 32 that is disposed opposite to the fixing member 31, and a support that fixes the fixing member 31 and the punching member 32 to the side plates 10b and 10c. The members 33a and 33b and springs 34 and 34 extending from the support members 33a and 33b are provided.

  The fixing member 31 is formed in a substantially rectangular plate shape, and a plurality of receiving holes 31a are provided on the surface on the hole forming member 32 side. The perforating member 32 is formed in a substantially rectangular plate shape, and a conical protrusion 32 a is provided on the surface on the fixing member 31 side. The fixing member 31 and the punching member 32 are connected to springs 34 and 34 provided on the inner sides of the support members 33a and 33b, respectively.

A pair of connecting arms 35 is provided in the middle of the support members 33a and 33b, and one of the connecting arms 35 is connected to the rotating shafts 24a and 24b. The connecting arm 35 is configured to support the pressing mechanism 20 described above. The spring 34 can be expanded and contracted in the lateral direction, and the fixing member 31 and the perforating member 32 facing each other are formed so as to be in contact with each other. As shown in FIG. 2, in the present embodiment, there are three protrusions 32a, but these can be arbitrarily changed.
Moreover, the shape of the receiving hole 31a and the projection part 32a can also be made into Fig.4 (a)-(c) so that it may demonstrate below.

As shown in FIG. 4A, the receiving hole 31a serving as the receiving portion of the protruding portion 32a is formed in a cylindrical shape, and the protruding portion 32a is formed in a conical shape. That is, each of the punching mechanisms 30 has a structure in which the holes are fitted, and the receiving holes 31a and the protrusions 32a are in an uneven relationship.
FIG. 4B shows a protrusion 32b formed with a tip of the protrusion 32a as a truncated cone, and FIG. 4C shows a protrusion in which a protrusion is formed on the peripheral surface of the protrusion 32a. The part 32c and the receiving hole 31c which receives the protrusion are shown. These differ in the shape of the hole when the protrusion 32a (32b, 32c) forms a through-hole in the target PET bottle 70 and the efficiency when performing continuous processing. If the protrusion is formed like the protrusion 32c, the burr formed when the through hole is formed becomes larger than the protrusion 32a, and the effect of maintaining the shape can be increased.

(Pet bottle shape change)
As described above, the PET bottle 70 compressed by the pressing mechanism 20 is sent to the hole forming mechanism 30, and a through hole is formed by the protrusion 32 a of the hole forming member 32. Here, the shape change of the PET bottle 70 by the pressing mechanism 20 and the punching mechanism 30 will be described based on FIGS.

  As shown in FIG. 5, the plastic bottle 70 is a plastic beverage container formed in a cylindrical shape. The PET bottle 70 includes a main body portion 71 and a screw-type cap (plug portion) 72. In the main body portion 71, one cylindrical side surface 71a facing the perforating member 32 side and the other facing the fixing member 31 side. And a cylindrical side surface 71b. As shown in FIG. 6, the PET bottle 70 pressed by the tapered pressing mechanism 20 is pressed near the cap 72 in the main body 71 and is compressed on the main body 71 side. The screw portion is deformed and is no longer useful, and the cap 72 is detached from the main body 71. The cap 72 removed here is accommodated in a cap dedicated collection box (not shown).

  The plastic bottle 70 pressed by the pressing mechanism 20 is sent to the punching mechanism 30, and the plurality of protrusions 32a are moved from one cylindrical side surface 71a to the other cylinder in a state where the plastic bottle 70 is fixed to the fixing member 31. If it penetrates toward the side surface 71b, it will be in the state of Fig.7 (a). FIG. 7B is an enlarged view of part A of FIG. 7A, and it can be seen that the outer surface of one cylindrical side surface 71a protrudes from the outer surface of the other cylindrical side surface 71b. Moreover, Fig.8 (a) is the figure seen from the one cylinder side surface 71a side, and is the state which has three through-holes. FIG. 8B is an enlarged cross-sectional view taken along the line BB.

  That is, by penetrating, burrs are formed on one cylindrical side surface 71a and the other cylindrical side surface 71b, and a catch occurs. This burr is used to prevent the plastic bottle 70 from being restored. That is, the PET bottle 70 is a material that is temporarily compressed by the pressing mechanism 20 but is restored when time passes. However, a through-hole is opened by the hole-forming mechanism 30, and the shape that is not restored by burrs is maintained.

(Function)
Next, the operation of the volume reducing device 1 will be described.
First, when the PET bottle 70 is inserted into the insertion port 5, an air hole is opened by a needle provided near the insertion port 5 and is fixed between the pressing belts 21 and 22. Further, a position detection sensor (not shown) provided in the vicinity of the insertion port 5 sends a drive signal to the drive motor 40 when detecting the plastic bottle 70. When the drive motor 40 starts driving, a driving force is transmitted to the rotating shaft 24a of the pressing belt 21, and the rotation of the pressing belt 21 is started. The inner side of the pressing belt 21 rotates downward, and the plastic bottle 70 is drawn downward. At this time, the other pressing belt 22 rotates so as to assist the drawing of the plastic bottle 70 in the traveling direction. The PET bottle 70 is gradually compressed by being drawn in the traveling direction. With this compression process, the volume of the main body 71 is reduced, and the cap 72 is detached from the main body 71 of the plastic bottle 70.

  When the PET bottle 70 is delivered from the pressing mechanism 20 to the punching mechanism 30, the second position detection sensors (not shown) provided on the side plates 10 b and 10 c in the vicinity of the punching mechanism 30 are moved to the position of the PET bottle 70. And a drive signal is transmitted to a second drive motor (not shown). Since the plastic bottle 70 has already been compressed, the plastic bottle 70 enters the space between the fixing member 31 and the punching member 32, and the support member 33a and the spring 34 interlocked with the second drive motor extend to the fixing member 31 side. . The PET bottle 70 has an upper end fixed to the sprockets 24 and 24 and a lower end (cap 72 side) fixed along the fixing member 31. In this state, the protrusion 32 a of the punching member 32 forms a through hole on one cylindrical side surface 71 a of the plastic bottle 70.

  The through hole penetrates to the outer surface of the other cylindrical side surface 71b, whereby a burr is formed. Therefore, even a material having a restoring force such as a plastic bottle 70 does not restore by taking air into the internal space after compression. As a result, it is possible to reduce labor and time required for fixing with a wire after compression, and to improve work efficiency during recycling. When temporary storage is performed, the storage space can be used effectively, so that the collection cycle can be prolonged.

  Moreover, since the main body 71 and the cap 72, which are made of different materials, are processed separately, the separation work after compression can be omitted. Further, in the pressing mechanism 20, the cap 72 is closed to open the air hole, and it is considered that the volume reduction device 1 is not contaminated without generating a plosive sound even if it is discarded with the contents inside. In addition, the drive source of the drilling mechanism 30 can also be driven from the drive motor 40 described above via a link mechanism.

  Moreover, it can replace with the volume reduction apparatus 1 mentioned above, and can also be set as the volume reduction apparatus 100 as shown in FIG. FIG. 9 is a front sectional view showing the volume reduction device 100. The volume reducing device 100 is provided with a pair of guide rollers 110 and 110 between the insertion port 5 and the pressing mechanism 20, and the perforating member 122 and the sword mountain projecting portion instead of the projecting portion 32 a of the perforating member 32. Except for the point provided with 122a, it is exactly the same as the volume reduction device 1 described in the above embodiment.

  The guide roller 110 has a plurality of guide pins 111 connected to the circumferential surface of the guide roller 110 at equal intervals. When the PET bottle 70 is inserted from the insertion port 5, it is delivered more smoothly by the guide roller 110. The punching mechanism 120 includes a punching member 121 and a second punching member 122, and is configured as sword mountain protrusions 121a and 122a so that the tip portions thereof face each other. The sword protrusions 121a and 122a form a through hole by being sandwiched from both sides of one cylindrical side surface 71a and the other cylindrical side surface 71b of the plastic bottle 70 delivered from the pressing mechanism 20. Thereby, a plurality of through holes are formed on both sides of the PET bottle 70, and a stronger burr is formed.

According to the embodiment described above, it is possible to prevent a material having a restoring force such as a PET bottle from being restored to its original shape after compression, thereby reducing labor during recycling.
In addition, even when the main body such as a plastic bottle and the cap are made of different materials, the cap is removed from the main body during compression by the pressing mechanism. Therefore, the sorting work is greatly reduced.
In addition, since there is a hole for venting air near the inlet, the PET bottle may be ruptured or residual liquid even when the plastic bottle is inserted in the opposite direction to the inlet or when there is residual liquid. Scattering can be prevented in advance.

  In the above-described embodiment, a plastic bottle is taken as an example, but the present invention is not limited to this. For example, it is also effective for plastic containers, cut pieces of paper after shredding, film cuts, and film cut pieces.
