DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing apparatus for binding an object to be packed such as waste with a binding band.

[0002]

2. Description of the Related Art In order to collectively dispose of wastes such as PET bottles, a packing apparatus that binds a plurality of waste lumps together is generally known.

FIG. 4 is a schematic configuration diagram of a conventional packing device. The packing device includes a main body 41, a protective cover 43 attached to the main body in an arch shape, and a protective cover 43.
And a binding table (not shown) is provided. FIG. 5 is a cross-sectional view of the protective cover 43 as viewed from the BB direction in FIG. A band groove 51 that opens upward is provided on the upper surface of the arch-shaped protective cover 43.
3 through the passage 53. An openable / closable flapper 47 is attached to the upper portion of the passage portion 53, and is in a closed state in a normal state, and is opened when a packaged object is bound, and the binding band 49 of the passage portion 53 is closed. The protective cover 43 is drawn out.

[0004] Waste packaging using such a packaging apparatus is performed as follows. First, a plurality of compressed and reduced wastes such as PET bottles are placed on a binding table surrounded by a protective cover 43. Then, by operating an operation unit (not shown), the packing device is operated, and the flapper 47 is opened. Thereby, the binding band 49 in the passage 53 is pulled out from the protective cover 43, and the waste on the binding table is bound.

[0005]

However, such a conventional packing apparatus has the following problems. The protective cover 43, through which the binding band 49 passes, is provided with a band groove 51 that is open at the top for pulling out the binding band. For this reason, until the waste is set on the binding table or during the packing operation, the particulate foreign matter attached to the waste may fall on the band groove and enter the band premises. In particular, when compressing and bundling waste such as plastic bottles with flexible outer shells, fine fragments of the waste are likely to be generated, and such foreign substances fall from the waste and enter the band premises. There are many.

The opening and closing operation of the flapper at the upper part of the passage cannot be smoothly performed by foreign matter such as granular foreign matter or fine debris that has entered the band premises, and the binding band is pulled out from the passage of the protective cover. May not be possible. Also, when binding the items to be packed,
In order to pull out the binding band, the flapper of the passage is in an open state, and foreign matter such as granular foreign matter or fine fragments may enter the passage. For this reason, when binding the next packaged object, the binding band may not be able to pass through the passage due to the foreign matter. As described above, there is a problem that the packing operation cannot be performed satisfactorily due to the foreign matter that has entered the band premises.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a packing apparatus capable of performing a good packing operation by preventing intrusion of foreign matter into a band premises. Main purpose.

[0008]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present application includes a protective cover having a band groove which stores a binding band and has an opening at an upper portion. A packing device for binding an object to be packed with a pulled-out binding band, comprising a lid portion provided on an upper portion of the protective cover and made of an elastic member for shielding the band groove, wherein the lid portion is a band formed by elastic force. Provided is a packing device characterized in that a groove can be opened and closed.

According to the present invention, since the cover for covering the band groove is provided, it is possible to prevent foreign substances from entering the band premises during the packing operation. That is, when the banding band passes through the band groove, the opening of the band groove is covered by the lid, so that even if foreign matter attached to the packaged object falls, Can be prevented from entering the band premises.

[0010] "Opening and closing the band groove by elastic force" means that the cover portion is deformed by the elastic force generated by an external force applied to the cover portion made of an elastic member to open the band groove, and the deformed cover portion is opened. This means that the band groove is closed by the part returning to its original state by elastic force. For example, it can be achieved by fixing one end of a lid for shielding the band groove to the upper part of the protective cover.

That is, when the binding band is pulled out from the band groove to the outside of the protective cover, the binding band pushes the lid upward, so that an upward external force is applied to the lid. For this reason, the lid portion is deformed, and a gap is formed in the shielded band groove such that the binding band can pass through, and the band groove is instantaneously opened. Therefore, it is possible to prevent foreign matter from entering the band premises at the time of binding, and to pull out the binding band from the protective cover without the lid becoming an obstacle.

Further, after the banding band is pulled out of the protective cover, the external force from the banding band disappears, but the deformed lid has an elastic force for returning to the original state. The groove immediately returns to its original or closed state. For this reason, even after pulling out the binding band,
No foreign matter enters the band groove.

That is, according to the present invention, when the banding band is pulled out, the band groove is instantaneously opened so that the banding band can pass through the banding band and closed immediately after the banding band is pulled out. Even if foreign matter such as granular foreign matter or fine debris attached to the waste falls on the portion, it is possible to prevent such foreign matter from entering the inside of the band groove.

Here, the material of the lid is not particularly limited as long as it is an elastic member. For example, rubber, synthetic resin, metal or the like can be used. The number and shape of the lids are not particularly limited as long as they can shield the band grooves and can be opened and closed by elastic force.
For example, the lid is formed of a plurality of flat elastic sheets,
One end of each sheet is fixed to the upper part of the protective cover, and the band groove can be shielded by the entire sheet. Further, the cover may be configured such that the band groove is shielded by one elastic sheet and one end of the sheet is fixed to the upper part of the protective cover.

In the invention according to a second aspect of the present invention, the lid portion includes a pair of two elastic sheets, each elastic sheet being inclined above the protective cover by a predetermined angle with respect to the upper surface of the protective cover. The packing device according to claim 1, wherein the packing device is provided to face each other, and upper portions of the respective elastic sheets are pressed against each other.

According to the present invention, since the pair of two elastic sheets constituting the lid portion are pressed against each other at the upper part, the band groove is shielded by each elastic sheet. For this reason, it is possible to prevent foreign substances from entering the band premises during the packing operation. That is, when the banding band passes through the band groove, the opening of the band groove is shielded by each elastic sheet, so that foreign matter such as granular foreign matter and fine debris adhered to the packaged object drops. Even so, the elastic sheet can prevent such foreign matter from entering the band premises.

Further, when the binding band is pulled out of the protective cover from the band groove, the binding band tends to pass through the elastic sheet, so that an external force is applied to the elastic sheet and each elastic sheet is deformed. Then, due to the deformation of the elastic sheet, the pressure contact state is released, a gap is formed between the elastic sheets to allow the binding band to pass, and the band groove is instantaneously opened. Therefore, it is possible to prevent foreign substances from entering the band structure during binding, and to pull out the binding band from the protective cover without the elastic sheet becoming an obstacle.

On the other hand, after the binding band is pulled out of the protective cover, no external force is applied from the binding band.
Since an elastic force for returning to the original state is generated in each deformed elastic sheet, the elastic sheet immediately returns to the original state, that is, the pressed state, and the band groove is closed. Therefore, even after the binding band is pulled out, no foreign matter enters the band groove.

That is, according to the present invention, the band groove is instantaneously opened when the binding band is pulled out and closed immediately after the banding is pulled out by the elastic sheet. Even if foreign matter such as granular foreign matter or fine debris attached to the object falls, it is possible to prevent the foreign matter from entering the inside of the band groove.

Further, the respective elastic sheets are provided so as to face each other at a predetermined angle with respect to the upper surface of the protective cover. For this reason, even if the foreign matter adhering to the package falls on the band groove, the foreign matter falls along the inclined outer surface of the elastic sheet. Therefore, foreign matter that has fallen from waste
Since the elastic sheet does not remain on the elastic sheet, it is possible to reduce the possibility of entering the band groove during the opening and closing operation of the elastic sheet.

Here, the material of the elastic sheet is not particularly limited as long as it is an elastic member. For example, rubber, synthetic resin, metal or the like can be used. Also, the shape of the elastic sheet is not particularly limited as long as it can shield the band groove. For example, the elastic sheet may be formed of a flat sheet.

When the binding band 9 is pulled out from the protective cover 3, the binding band 9 passes between the sheets 5, so that the pressed state is released and the band is opened. still,
In this embodiment, a pair of two rubber sheets are used as the lid, but the present invention is not limited to this as long as it has elasticity, and may be made of synthetic resin, metal, or the like.

In the thus configured waste volume reducing machine, the compression processing and the packing processing of the PET bottle are performed as follows.

A plurality of plastic bottles to be processed are put in through openings provided in the upper part of the hopper 15. Hopper unit 15
Is dropped by its own weight, passes through the discharge port 29 in the hopper 15, and is introduced into the compression unit 17. When a certain amount of plastic bottles are introduced into the compression chamber 17 from the hopper section 15, the main cylinder 23 descends and crushes the plastic bottles to a thickness that can pass through the height of the outlet 25, and the compressed plastic bottles are crushed. Generate a block of. Thereafter, the compressed PET bottle is discharged from the outlet 25 to the packing unit 19 by the extrusion cylinder 21. The compressed PET bottle block is transported to the binding position 27 of the packing device.

The binding band 9 housed in the main body 1 of the packing device is introduced into the passage 13 of the protective cover 3 of the packing device. In this state, a pair of two rubber sheets 5 fixed to the upper part of the protective cover 3
And the band groove 11 is shielded. For this reason, particulate foreign matter adhered to the plastic bottle on the binding table and fine debris generated when the plastic bottle is compressed are protected from the plastic bottle block by the protective cover 3.
Even if it falls upward, it falls along the outer surface of the inclined rubber sheet 5, so that it can be prevented from entering the inside of the band groove 11.

In order to bind the PET bottle blocks on the binding table, an operation switch (not shown) provided on the packing device is operated. At this time, the flapper 7 of the passage 13 in the protective cover 3 is opened, and the binding band 9 is pulled out from the passage 13 upward. At this time, a pair of two rubber sheets 5 are pressed against each other on the upper part of the protective cover 3, but the binding band 9 that has moved upward passes through the pressed portion of the two rubber sheets 5. Since an external force is applied to the rubber sheet 5 by passing through the binding band, each rubber sheet 5 is deformed by an elastic force. For this reason, each rubber sheet 5 has an opening large enough to allow the binding band to pass through instantaneously. The binding band 9 passes through the opening and is drawn out of the protective cover 3 to bind the PET bottle blocks on the binding table. Therefore, the rubber sheet 5 can prevent foreign substances from entering the band premises, and can pull out the binding band 9 from the protective cover 3 without the rubber sheet 5 becoming an obstacle.

When the binding band 9 is pulled out of the protective cover 3, no external force is applied from the binding band 9 to the rubber sheet 5, but each deformed rubber sheet 5 has an elasticity that tends to return to the original state. Power is occurring. For this reason, each rubber sheet 5 is immediately brought into a pressure contact state, and the band groove 11 is brought into a closed state. Therefore, no foreign matter enters the band groove 11 after the banding band 9 is pulled out, that is, during the operation of banding the PET bottle blocks.

That is, in the packing device in the waste volume reducing machine of the present embodiment, the band groove 11 is instantaneously opened by the rubber sheet 5 when the binding band 9 is pulled out, and immediately closed after the pulling out. Become. For this reason, even if foreign substances, such as granular foreign substances and fine debris, attached to the waste fall into the band structure during the packing operation, it is possible to prevent such foreign substances from entering the inside of the band groove 11. And, by foreign matter that has entered the premises of the band,
It is possible to prevent the opening / closing operation of the flapper 7 of the binding band 9 from being obstructed, and to prevent the binding band 9 from being pulled out from the protective cover 3. Further, the passage of the binding band 9 in the protective cover 3 is not obstructed by a foreign matter that has entered the band premises.

In the present embodiment, the packing device binds the PET bottles. However, it is needless to say that the packing device can be configured to bind other wastes or items to be packed. Further, in the present embodiment, the packing device is used as a packing unit of the waste volume reducing machine. However, the packing device may be used alone, or another device such as a book,
