Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic volume reducing packing device for packing waste plastic containers and other plastics by reducing their volume. In particular, the present invention relates to a reduced-volume plastic packaging device in a plastic-volume reduction packaging device that automatically performs processes from compression / volume reduction of waste plastic to packaging / binding.

[0002]

2. Description of the Related Art It is known that waste plastics are compressed and deformed for the purpose of disposal, reuse, etc. to reduce the volume to form an aggregate, which is then packaged in a packaging bag. It stores waste plastic in a facility for recycling and also
This is an effective technique because it is easy to handle, such as transporting it to a storage location.

[0003] By the way, in the conventionally used packaging, it is general to put an aggregate of waste plastics which have been compressed and deformed and reduced in volume into one packaging bag, or to tie them together with a band after packaging. there were. Specifically, one packaging bag is opened at the outlet of the passage through which the waste plastic aggregate is discharged, the aggregate is pushed into the packaging bag, and finally the opening of the packaging bag is sealed. It is a thing.

In the above conventional technique, it is necessary to use one packing bag at a time. Therefore, when the processes from compression / volume reduction of waste plastic to packing / bundling are automatically performed, a plurality of packing bags are stacked. It will be stored, taken out one by one, and put on the assembly to be packed. Therefore, a device related to the packing work and its control, particularly, a device for setting the packing bags one by one at a predetermined position and its control become complicated, and there is a problem that the efficiency of automation of waste plastic processing is poor.

In order to solve this problem, a technique has been proposed in which a packing operation can be easily carried out by wrapping an assembly of waste plastic so as to wrap it. For example, JP-A-200
JP-A 1-259893 discloses that a feeding device for feeding two sheet-shaped resin thin film materials is provided at the exit of a conveying passage through which the assembly is extruded and conveyed, and is wound so as to wrap the assembly, This is a technique for facilitating the packing work by heat-sealing the width direction edge portion and the side edge portion.

However, in the above-mentioned conventional technique, since the packaging bag is formed by heat-sealing and adhering the edges of two sheet-shaped resin thin film materials, when heat-sealing is not sufficient. Creates a gap between the edges of the two sheets, and the inclusions, that is, the fragments of the waste plastic aggregate, fall outside, or the residue of waste plastic (eg, liquid such as drinking water) leaks out. Then, there is a problem in that the transportation and storage of the waste plastic aggregate is hindered.

[0007]

SUMMARY OF THE INVENTION In view of the above situation, an object of the present invention is to provide a plastic volume-reducing packing device capable of packing waste plastic aggregates with simple control. Further, the present invention intends to provide a plastic volume reduction packaging device suitable for automation of processing from compression / volume reduction of waste plastics to packaging / bundling. In addition, it is another object of the present invention to provide a plastic volume-reducing packaging device which is highly reliable in packaging and is excellent in handling such as transportation and storage of waste plastic aggregates.

[0008]

In order to achieve the above object, according to the invention as set forth in claim 1, a volume reducing means for compressing and deforming the waste plastic to reduce its volume and forming an aggregate of the waste plastic. An extruding and conveying means for extruding and conveying the aggregate, a conveying passage for passing the aggregate extruded by the extruding and conveying means in a state of being constrained from the surroundings, and arranged on the outlet side of the conveying passage, In a plastic volume-reducing packing device including packing means for packing the aggregate, the packing means is rotatably disposed at a position facing the outlet of the transport passage, and is a tubular resin thin film material. Is a roll wound in a strip shape, between the outlet of the transport passage and the roll are disposed face-to-face with a predetermined distance from the transport passage outlet, the tubular resin thin film material from the roll Transport A grip that has a feeding means for feeding to the road side, an upper arm portion and a lower arm portion, and the arm portion grasps and opens at least an end portion of the tubular resin thin film material fed by the feeding means. Holding means, a slide device for sliding the holding means in the axial direction of the transport passage over a predetermined moving distance, and a heat-sealing means for heat-sealing the tubular resin thin film material in the width direction. And a cutting means for cutting the tubular resin thin film material in the width direction.

According to the present invention, a volume reducing means for compressing and deforming waste plastic by a hydraulic cylinder or the like to reduce the volume to form an aggregate of waste plastic, and an extension movement of an extrusion piston or the like extrudes and conveys the aggregate. And a transport passage for passing the aggregate extruded by the extrusion transport means while restraining the expansion (expansion of the aggregate) from the surroundings, and an exit side of the transport passage. In a plastic volume packing apparatus which has been conventionally used and is provided with a packing means for packing the aggregate, the packing means has a great feature.

That is, the packing means in the present invention is first rotatably arranged at a position facing the outlet of the transfer passage, and comprises a roll in which a tubular resin thin film material is wound in a strip shape. . Here, a roll in which a tubular resin thin film material is wound in a strip shape means all rolls in which a tubular resin thin film material having a uniform continuous length is wound in a strip shape. It includes. As long as the tubular resin thin film material is wound in a band shape, the tubular resin thin film material in the present invention is wound in a band shape even if it is a form such as a roll in which a resin sheet is wound at first glance. And a tubular film or the like wound on the roll.

In the present invention, any tubular resin thin film material can be applied, but more preferably,
It is preferable to use a thin film material made of polyethylene resin. This is because it is highly versatile, has appropriate strength, and is excellent in heat fusion.

As described above, according to the present invention, since the roll in which the tubular resin thin film material is wound in a strip shape is rotatably arranged at the position facing the outlet of the transport passage, the tubular resin thin film material is provided. When the end portion of is rolled toward the transfer passage, the roll rotates and the tubular resin thin film material wound in a strip shape is pulled out toward the transfer passage.

Further, according to the present invention, the exit of the transfer passage and the roll are arranged face-to-face with a predetermined distance from the exit of the transfer passage, and the cylindrical resin thin film material is placed on the roll from the roll. It has a feeding means for feeding to the side of the transport passage. Here, the feeding means in the present invention is a concept including all the structures that can pull out an end portion of a tubular resin thin film material and feed it in a predetermined direction. The thin resin thin film material is sandwiched between the ends, and in this state, the two rollers are rotated to pull out the tubular resin thin film material that is wound in a strip shape, and to draw it out in a predetermined direction. Applicable

Further, the feeding means in the present invention is arranged at a position facing a predetermined distance from the exit of the conveying passage. This is because the waste plastic aggregate is discharged from the exit of the transport passage. Therefore, the discharge of the aggregate will be hindered unless the feeding means is arranged at a distance of at least the entire length of the aggregate. Is.

That is, in the present invention, the predetermined distance is a distance corresponding to the total length of the aggregate after the waste plastic has been compressed and reduced, or a distance longer than that, and the waste plastic to be obtained. It may be appropriately changed according to the size (total length) of the aggregate.

Further, in the present invention, the arm portion has an upper arm portion and a lower arm portion, and the arm portion vertically moves at least an end portion (edge portion) of the tubular resin thin film material fed by the feeding means. It is provided with a gripping means for gripping from and opening. The tubular resin thin film material is a roll wound in a band shape as described above. In other words, it is in the state of a roll in which a tubular resin thin film material is flattened into a sheet shape and wound. Therefore, unless the end portion (edge portion) of the portion where the tubular resin thin film material is fed out is opened to have a substantially rectangular shape or a substantially tubular shape, when the waste plastic aggregate is discharged from the transport passage. However, it is difficult to enclose and pack the aggregate.

However, according to the present invention, the upper and lower arms have an upper arm portion and a lower arm portion, and both upper and lower arm portions vertically move at least the end portion (edge portion) of the tubular resin thin film material fed by the feeding means. Since the gripping means for gripping and opening from the direction is provided, such difficulty does not occur. That is, by holding at least an end portion of the tubular resin thin film material by the holding means and holding the opening portion in a substantially cylindrical or substantially rectangular state, it is easy to insert the waste plastic aggregate into the opening portion. Therefore, the packaging can be done smoothly.

Here, the gripping means in the present invention is a mechanism having an upper arm portion and a lower arm portion, and the arm portion is capable of gripping the tubular resin thin film material from above and below. Then, while grasping the tubular resin thin film material from the top and bottom, pull up only the upper arm part, pull down only the lower arm part, or both are rolled into a band-like appearance. This is a concept that includes all means capable of opening an end of the sheet-shaped tubular resin thin film material.

For example, the tips of the upper arm portion and the lower arm portion have a structure like a suction cup, and the cylindrical resin thin film material is gripped (sucked) by this suction cup, and the upper arm portion and the lower arm portion are brought into contact with each other. The structure may be such that the ends of the tubular resin thin film material are opened by operating so as to be separated from each other, and an air nozzle is provided at the tips of the upper arm portion and the lower arm portion to suck the air into the tubular resin. A thin film material that is gripped (sucked) and the end of which is opened by the same operation as described above can also be used as the gripping means in the present invention. Needless to say, even if the tubular resin thin film material is mechanically gripped vertically to open the end, it corresponds to the gripping means in the present invention.

The upper arm portion and the lower arm portion can be functionally used if at least one is provided, but preferably,
It is preferable to provide two or more at positions substantially on the same straight line in the width direction of the tubular resin thin film material. This is because it is easy to hold the opening in a substantially cylindrical shape or a substantially rectangular shape.

Further, according to the present invention, since the gripping means is provided with the slide device which slides in the axial direction of the transfer passage over a predetermined moving distance, the end portion of the tubular resin thin film material is opened. By sliding the gripping means in the axial direction of the transport passage in this state, the tubular resin thin film material can be mounted so as to cover the entire outside of the transport passage from the outlet side. That is, the slide device according to the present invention plays a role of covering the entire outer side of the transfer passage with the tubular resin thin film material.

At this time, since the tubular resin thin film material is a roll wound in the width direction in a continuous band shape, the tubular resin thin film material is processed as a packing bag for packing the waste plastic aggregate. You have to do it. However, in the present invention, the tubular resin thin film material is provided with the heat fusion means for heat-sealing the tubular resin thin film material in the width direction and the cutting means for cutting the tubular resin thin film material in the width direction. The thin film material can be easily processed into a packaging bag. That is, the tubular resin thin film material fed by the feeding means is heat-fused in the width direction by the heat-fusing means to form the bottom portion of the packaging bag when it has an appropriate length, and the heat-fusing portion is further formed. If you cut the part on the roll side with the cutting means in the width direction,
That part becomes the bottom and becomes a bag for packing.

Here, the predetermined moving distance for the gripping means to slide is the distance required to cover the tubular resin thin film material over the entire outside of the transport passage (that is, about the entire length of the packaging bag). Is a distance equivalent to the above-mentioned predetermined distance (distance corresponding to the total length of the aggregate after the waste plastic has been compressed and reduced or more). This is because the feeding means is arranged at a position spaced a predetermined distance (about the length corresponding to the total length of the assembly) from the exit of the conveying passage, and the gripping means from the position is the cylinder from which the feeding means is fed. The reason is that the resinous thin film material is grabbed and directly covered on the outer side of the transport passage.

That is, the predetermined moving distance is the moving distance required for the gripping means to cover the tubular resin thin film material over the entire outside of the conveying passage, in other words, The distance is about the sum of the distance from the feeding means to the exit of the conveying passage and the total length of the packaging bag processed from the tubular resin thin film material, or more. Therefore, this predetermined moving distance may be adjusted depending on the total length of the waste plastic aggregate, the location of the feeding means, and the like, and can be appropriately changed as necessary.

The slide device according to the present invention is of a concept including all that reciprocally move the gripping means along the axial direction of the carry-out passage. For example, a mechanism of sliding the chain on a traveling rail by chain drive is used. There are things. Further, in the present invention, as the heat-sealing means, any means can be used as long as the resin-made thin film material can be heat-sealed. Further, as the cutting means in the present invention, any means can be applied as long as the resin thin film material can be appropriately cut.

According to the present invention including the packing means configured as described above, the end portion of the tubular resin thin film material is pulled out from the roll in which the tubular resin thin film material is wound in a strip shape and inserted into the feeding means. In this state, the feeding means feeds the tubular resin thin film material to the conveying passage side, and the upper and lower arm portions of the gripping means grasp the ends of the tubular resin thin film material to open. And is moved to the transfer passage side by a slide device. The tubular resin thin film material that has been fed to an appropriate length is heat-sealed in the width direction by the heat-sealing means to form the bottom of the bag. Then, the cutting means cuts the tubular resin thin film material on the roll side of the heat-sealing portion to form a packaging bag.
By mounting this packing bag so as to cover it from the exit side of the transfer path to the entire outside of the transfer path by a slide device, the waste plastic aggregate extruded and transferred from the transfer path is pushed by the extrusion transfer means to press the packing bag. To include. If the opening of the packing bag is heat-sealed by the heat-sealing means after the assembly is completely enclosed in the packing bag, the assembly can be completely stored in the packing bag.

The heat-sealing means is used to form the bottom of the packing bag, and at the same time, is used to heat-seal the assembly after it is housed in the packing bag to seal the packing bag. However, in the present invention, one movable heat-sealing means may be used, or two heat-sealing means may be individually installed. That is, the heat-sealing means in the present invention may be any as long as the tubular resin thin film material is heat-sealed in the width direction to form the bottom of the packing bag and the packing bag can be sealed. Of.

Therefore, according to the present invention, since the roll of the tubular resin thin film material wound in the shape of a band is used, it suffices to control the feeding operation of the tubular resin thin film material by the feeding means. With this control, the packing work of waste plastic aggregates can be performed, and the structure of the device itself can be simplified. Moreover,
Since it suffices to unroll the cylindrical thin film material made of resin, the efficiency of automation of the packing operation is significantly improved as compared with the case where the packing bags are taken out one by one and packed. In addition, in the present invention, since the packaging bag is formed by heat-sealing only both ends of the tubular resin thin film material, the sheet-shaped thin film material is formed over the entire circumference from both ends to the side edge portion. Compared with the case of heat-sealing, there are far fewer heat-sealed portions. Therefore, the heat-sealed portion is less likely to be peeled off, and there is little fear that fragments of the assembly will fall off to the outside or that the residue will leak out. In other words, highly reliable packaging is possible.

Further, since the cylindrical resin thin film material roll is used, if the control is changed according to the total length of the assembly, a packaging bag of any length can be formed and various automatic operation can be performed. There is also an advantage that can be applied to the conditions.

By the way, the plastic volume-reducing packing device according to the above-mentioned claim 1 can be rephrased as follows.

That is, according to the invention described in claim 2, in the plastic volume-reducing packing device according to claim 1, the tubular resin thin film material is delivered by the delivery means, and the tubular shape is delivered. At least an end portion of the resin thin film material is opened by the gripping means, and the tubular resin thin film material is held in the opened state and the gripping means slides in the axial direction by the slide device. Is fed from the roll, the tubular resin thin film material that is fed is heat-sealed in the width direction by the heat-sealing means to form the bottom of the bag, then the cutting means from the heat-sealing portion. Also, the cylindrical resin thin film material is cut on the roll side to form a packaging bag, and the packaging bag covers the slide device of the slide device from the outlet side of the transportation passage to the entire outside of the transportation passage. It is mounted, and the extruding and conveying means extrudes the aggregate from the conveying passage so that the aggregate is enclosed in the packing bag and packed, and the opening of the tubular resin thin film material is inserted into the heat fusion means. It is characterized in that the packaging is completed by heat fusion.

According to the invention of claim 3, claim 1
Alternatively, in the plastic volume-reducing packaging device according to item 2, a binding device that winds a binding material around the outside of the packaging bag in which the assembly is included is provided on the outlet side of the transport passage. .

The waste plastic aggregate is compressed by the volume reducing means, but tends to expand due to its reaction force. This reaction force may break the packaging bag. In order to prevent such a situation, in the present invention, a binding device that winds a binding material (band) around the outside of the packaging bag in which the assembly is included is provided on the exit side of the transport passage. This allows the binding material to be wrapped around the packing bag by an arbitrary number of windings while the assembly is being stored in the packing bag, and there is no concern that the packing bag will swell and the packing bag will be lost. The sex will be further increased.

7 and carry the film 7 to the front of the pay-out roll 18. Then, a drive motor (not shown) for the feeding roll 18
Is driven to feed the film 7 into the rear guide 19 while being fed by the rotation of the feeding roll 18, and is then directly passed through the film insertion ports (not shown) of the cutting device 14 and the front sealing device 13a to an appropriate position on the conveying passage 3 side. Keep it in.

This is, so to speak, a preparatory stage in the automatic packing operation of the waste plastic assembly 4.

When the automatic packing operation is started, the upper arm portion 10 and the lower arm portion 11 of the clamp device 9 (see FIG. 1) are attracted by the attraction force of the attraction pad 20 as shown in FIG. 2 (a). The clamp device 9 slides toward the carry-out passage 3 (in the direction of the arrow) by the slide device 12 (see FIG. 1) while holding the state in which the end portion of the film 7 is grasped from above and below and opened. When the film 7 is fed to an appropriate length, the front sealing device 13a heat-bonds the film 7 in the width direction to form the bottom portion A of the packaging bag 7'as shown in FIG. 2 (b). Next, the cutting device 14 cuts the roll 6 side from the heat-sealed portion to complete the packaging bag 7 '. As shown in FIG. 2B, the clamp device 8 slides by the slide device 12 while keeping one end of the packaging bag 7'formed from the film 7 (on the side of the carry-out passage 3) open.

The volume-waste plastic assembly 4 is
By the extension motion of the extrusion piston 2 ′, which is a part of the extrusion conveyance means, the extruding piston 2 ′ passes through the conveyance passage 3 while being constrained at its periphery and is conveyed to the outlet. Then, as shown in FIG. 2 (c), it is gradually extruded into the packaging bag 7 '.

Then, as shown in FIGS. 2 (c) to 2 (e), the packing bag 7'is gradually wrapped around the band 16 from the outside by the binding device 15 (see FIG. 1). Since the expansion of the assembly 4 is restrained by the band 16, the reduced volume can be accommodated in the packaging bag 7 ′ without substantially breaking it. The band 16 is preferably made of polypropylene resin in terms of versatility and strength.

When the band 16 is properly wound around the entire length of the packing bag 7 ', the rear sealing device 13b (see FIG. 1) heats the opening of the packing bag 7'as shown in FIG. 2 (f). The packaging is completed by fusing (B portion in the figure).

It is a device having a size of m and processing the waste plastic into a substantially rectangular parallelepiped aggregate having a length of about 640 mm, a width of about 430 mm and a height of about 350 mm.

A volume reducing machine 1 which is a volume reducing means for reducing the volume of waste plastic is arranged at approximately the center of the whole, and the waste plastic is carried into the volume reducing machine 1 by a belt conveyor (not shown). It is thrown in. When the waste plastic that has been put in is activated from the control panel 25, the driving machine 24 operates and the volume reducing machine 1 compresses and deforms it to reduce the volume and form an aggregate. The formed aggregate is carried out to the exit of the conveying passage 3 by the extrusion conveying device 2 which is the extruding conveying means, the packing means 5 packages the aggregate as described above, and the bundling device 15 automatically moves to the vicinity of the conveying passage. The assembly 4a, which has been slid, wound the band 16 around the assembly, and completed the packaging, is carried out to the vicinity of the exit of the transport passage 3 as shown in FIG. afterwards,
The assembly 4a slides as shown by the arrow in FIG. 4 and is carried onto the roller conveyor 26 (4b), and while sliding down on the roller conveyor 26, the assembly 4c is collected at a predetermined place.

In this way, the waste plastic is compressed and
The series of packing operations from volume reduction to packing and bundling are all performed automatically.

The plastic volume-reducing packing device of the present invention is not limited to the above-mentioned illustrated example, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, when installing a plastic volume reduction packaging device, if the installation space is limited,
The roller conveyer 26 of FIG. 4 is arranged below the conveying passage 3 so that the aggregate 4a carried out from the conveying passage 3 is dropped as it is and slid on the roller conveyer to be collected at a predetermined place. Is also possible. In this way, by changing the arrangement of the roller conveyor 26, it is possible to install the entire device on a small site. Further, the film supply device 8 shown in FIG. 1 has a cutting device 14 and a front sealing device 13a.
You may make it integrated by incorporating and.

As described above, according to the plastic volume-reducing packing device of the present invention, since the complicated control and device for taking out the packing bags one by one are unnecessary, the feeding operation of the roll is controlled. Packing work of waste plastic aggregates can be performed with simple control. Furthermore, since the tubular resin thin film material is fed from the roll,
The efficiency of processing from compression and volume reduction of waste plastic to packing and bundling is improved compared to taking out packing bags one by one,
Suitable for automation. Further, even if the total length of the assembly is changed, the entire length of the packaging bag can be easily changed by merely adjusting the roll-out amount. In addition, since the heat-sealed portion is small, the heat-sealed portion is not easily peeled off, the packaging is highly reliable, and the handling such as transportation and storage is excellent.
