BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse compressing and packing apparatus, and more particularly to a method for compressing a bulky refuse such as paper or plastic sheet put in a refuse bag and keeping the compressed state. By doing so, even if the compressed state is released when the next garbage is thrown in, the garbage stored in the garbage bag is prevented from expanding and the garbage bag of the same volume is naturally put in the garbage bag A garbage compactor that can store about 5 times the amount of garbage and that is effective in reducing the costs of both the garbage disposal side and the garbage disposal side when disposing a large amount of garbage at a business establishment, etc. The present invention relates to a refuse compressing and packing apparatus which can prevent swelling of refuse from being slightly restored, thereby facilitating carry-out.

[0002]

2. Description of the Related Art Garbage discharged from business establishments such as general offices has a large volume of paper, and tends to be shredded especially in a shredder to maintain the confidentiality of documents. This is a factor that further increases the volume.

[0003] Recently, resins such as plastic sheets are very often used for packaging of commonly distributed products such as foods and office supplies, and when this becomes garbage, it becomes fluffy and bulky. It is a lot of waste with low density and light weight.

[0004] Since the amount of garbage in this business is large, it is a fact that the garbage is charged to a large extent. Specifically, per garbage bag (not per unit weight) at the time of collection of the garbage. ) Generally, a fixed amount of disposal costs are collected only for business-related waste.

[0005] Therefore, on the garbage discharge side of business establishments, etc.,
Garbage such as paper and plastic sheets can be stored in one bag because the weight of the garbage can be reduced and the processing cost increases. Therefore, from the viewpoint of cost reduction, more efficient garbage discharge technology, that is, reduce the amount of garbage that can be stored in one bag There has been a demand for a technique capable of increasing the amount of waste, but there has not been provided any refuse compression packing apparatus capable of compressing refuse in a refuse bag to reduce the volume.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and an object of the present invention is to insert a garbage bag held in a garbage bag holding section. The compressed garbage is pressed and compressed by the pressing portion while the garbage is kept in the garbage bag, and the compressed state is maintained until the next garbage is charged, so that the garbage that has been charged before is released even if the pressed state is released. In order not to swell and return to the original volume, and to be able to surely reduce the volume, the amount of garbage that can be stored in the garbage bag is set to 4 to 5 times the conventional amount, and further packed in the device. By doing so, it is possible to prevent swelling of the refuse from being slightly restored, facilitate the carry-out, and efficiently process the refuse.

Another object is to load a garbage bag for storing garbage on a bottom plate supported by a compression spring, and to lower the pressing portion until the compression spring is deformed by a predetermined amount, so that the bottom plate and the pressing portion are separated from each other. By pressing the refuse put into the refuse bag between the refuse bags, the refuse can always be compressed with a constant amount of force irrespective of the remaining amount of refuse in the bag. The purpose is to allow a certain amount of garbage to be stored per bag.

[0008] Still another object is to dispose a lower limit switch below the bottom plate, whereby the dust put into the garbage bag is pressed between the lowering pressing portion and the bottom plate, and the compression spring is moved. It is to allow the limit switch to detect that the bottom plate has descended due to the quantitative compression, and to transmit a pressing completion signal so that the pressing portion can be stopped on the spot, and thereby the dust can be removed with a predetermined magnitude of force. The goal is to further reduce the volume of the refuse by allowing it to continue to be compressed.

Another object is to dispose a pressing portion so as to be sandwiched between a pair of opposing guide members having a slit formed in a vertical direction, and to dispose a manual or electric driving device outside each of the two guide members. By connecting the driving device and the pressing portion by a connecting plate communicating from the outside to the inside of the guide member through the slit, the pressing portion and the pressing portion can be moved up and down from the outside of the guide member in which the garbage bag is stored. The garbage bag is prevented from being broken by the movable member of the driving device during the operation of the pressing portion.

Still another object is to open the abutting plate at a standby position above the pressing portion by abutting against a baffle plate attached to the guide member in parallel with a surface direction of the guide member and not abutting against the baffle plate. At the position, a pair of opening and closing bodies that are closed by the tension force of the tension spring are attached to the pressing part via hinges, so that when the garbage is thrown in, the opening and closing body opens automatically, and the garbage bag passes through the garbage bag from the trash inlet. Then, the refuse can be put in, and when the refuse is compressed, the opening / closing body is automatically closed so that the refuse in the garbage bag can be pressed by the lower surface of the garbage so that the refuse can be put in. The simplification and simplification of the operation are to be achieved.

Another object of the present invention is to make it possible to switch between the injection of dust and the compression by simply moving up and down without using a complicated mechanism by the structure of the opening and closing body of the pressing portion. It is another object of the present invention to provide a compact and highly reliable refuse compression packing device.

Still another object is that the band can be packed in the apparatus while the dust is compressed by the band holding section that holds the band sent from the band supply section with a constant tension and the band holding section that is detachable from the band. The purpose of the present invention is to prevent the swelling of garbage from being slightly restored and to facilitate carrying out.

4c is fitted so as to just fit into the notch 35a of the frame support 35. After the attachment, as shown in FIG. 6, the door 51 is closed and the slide lock 53 is slid in the direction of arrow B to lock. As a result, the limit switch 54 is operated, and the refuse compression packing apparatus 1 can be used.

When the electric switch 50 is turned on to turn on the power lamp 49, as shown in FIG. 14, the lid 60 is opened in the direction of arrow R, and the dust 32 is thrown in the direction of arrow S from the dust inlet 44a. . Since the pressing portion 2 is at the standby position H and the opening / closing body 15 is open, the pressing portion 2 penetrates from the garbage inlet 44a to the garbage bag 21, and the garbage 32 is normally inserted into the garbage bag 21. Going to be stored.

Next, as shown in FIG. 15, when the lid 60 is closed in the direction of arrow T and the down switch 8 is pressed, the pressing portion 2 descends in the direction of arrow I. Automatically close in direction. The pressing portion 2 goes down as it is, and after being integrated with the garbage bag holding portion 3, goes down together in the direction of arrow P as shown in FIG. 16, and presses and compresses the garbage 32. Since the air in the garbage bag 21 goes out through the hole 15a of the opening / closing body 15, there is no possibility that a reaction force is generated due to the air being trapped.

As shown in FIG. 16, the compression spring 43 of the bottom plate floating mechanism 4 is contracted in the direction of the arrow U with the increase of the pressing force, and when the pressing force reaches, for example, about 60 kgf, the bottom plate 41 is moved to the lower limit. When the switch 5 comes into contact with the actuator 5a, the lowering of the pressing portion 2 stops. Pressing part 2
Stops at the stopped position until the next time the refuse is pressed, the depression switch 6 is pressed, so that the compressed state is maintained. Therefore, even if the garbage 32 contains a large amount of air, such as paper or plastic garbage, it continues to be compressed for a long time to release air, and the garbage becomes hazy. Without returning to
The volume can be reliably reduced to about 1/5 of the non-compressed state.

When additional dust 32 is to be thrown in, the raising switch 6 must be pressed to raise the pressing portion 2 to the upper standby position H, and then the above procedure is repeated. Even if the dust 32 is erroneously thrown in when the pressing part 2 is not at the upper standby position H, if the amount is small, the opening / closing body 15 is automatically opened when the pressing part 2 returns to the standby position H, and Garbage 32
It is safe because it falls into the garbage bag 21.

Next, a method of packing the refuse bag 21 containing the refuse 32 in a compressed state will be described. In FIG. 20, the band 205 coming out of the band supply unit 200 is the band guide 204 and the first band holding unit 3 in the slot 44a.
01 to the band holding portion 400 fixed to the bottom plate 41
And reaches the second band pressing portion 302 facing the first band pressing portion 301, and exits outside the apparatus. In this state, the compression of the refuse bag 21 containing the refuse 32 is repeated, and after the compression is sufficiently completed, the pressing portion 2 is raised to the upper standby position H, and the inner frame 33 and the outer frame 34 are removed from the refuse bag 21.

In the above state, as shown in FIG.
5 is cut by the first band holding portion 301, and the cut portion is inserted into the first band holding portion 301 again through the tip of the opening / closing body 15 of the pressing portion 2. The band 205 is also pulled out from the second band holding portion 302, and is inserted into the second band holding portion 302 again through the end of the opening / closing body 15 of the pressing portion 2.

Subsequently, as shown in FIG. 22, the pressing portion 2 is lowered to compress the garbage bag 21 containing the garbage 32. After the compression is completed, the door 51 is opened, and the band 205 is bound at the upper portion of the pressing portion 2.

After the binding, as shown in FIG. 23, when the door 51 is closed again and the pressing portion 2 is raised to the upper standby position H, the garbage bag with the band can be taken out by opening the door 51.

In another embodiment, as shown in FIG.
From the lower part of the door 51, through the band holding part 400 fixed to the bottom plate 41 from the first band holding part 301 in the insertion port 44a and the insertion port 44a. In this state, the compression of the refuse bag 21 containing the refuse 32 is repeated, and after the compression is sufficiently completed, the pressing portion 2 is raised to the upper standby position H, and the inner frame 33 and the outer frame 34 are removed from the refuse bag 21.

In the above state, as shown in FIG.
5 is cut by the first band holding portion 301, and the cut portion is inserted into the second band holding portion 302 from the upper surface of the garbage bag 21 through the back side of the door 51.

Then, as shown in FIG. 26, the pressing portion is lowered to compress the garbage bag 21 containing the garbage 32. After the compression is completed, the door 51 is opened and the band 205 is bound at the front of the garbage bag 21.

After the binding, as shown in FIG. 27, when the door 51 is closed again and the pressing portion 2 is raised to the upper standby position H, the banded garbage bag can be taken out by opening the door 51.

As shown in FIG. 28, by using the refuse compressing and packing apparatus 1, as shown in FIG. It is possible to compress and store it. In the above embodiment, the drive device 10 is described as being of an electric type, but this is not limited to an electric type and may be a manual type.

[0072]

According to the present invention, the waste put in the garbage bag held by the garbage bag holding portion as described above is compressed by pressing the garbage in the garbage bag with the garbage bag kept in the garbage bag. Since the compressed state is maintained until the time of charging, even if the pressed state is released, the previously input dust does not expand and return to the original volume, and the volume can be surely reduced. The amount of garbage that can be stored in the garbage bag is 4 to 5
In addition, by packing inside the apparatus, there is an effect that it is possible to prevent the swelling of the garbage slightly, to facilitate the carry-out, and to efficiently treat the garbage.

A garbage bag for storing garbage is loaded on the bottom plate supported by the compression spring, and the pressing portion is lowered until the compression spring is deformed by a predetermined amount, so that the garbage bag is moved between the bottom plate and the pressing portion. As we pushed garbage put in,
Regardless of the remaining amount of refuse in the bag, the refuse can always be compressed with a constant amount of force, and as a result, a constant amount of refuse can be stored per bag.

Further, a lower limit switch is disposed below the bottom plate, and the dust put in the garbage bag is pressed between the descending pressing portion and the bottom plate, and the bottom plate is compressed when the compression spring is compressed by a predetermined amount. Since the limit switch detects the lowering and sends a pressing completion signal to stop the pressing portion on the spot, it is possible to continue compressing the garbage with a predetermined amount of force and reduce the volume of the garbage. An effect that can be further reduced is obtained.

Further, a pressing portion is provided so as to be sandwiched by a pair of opposing guide members having slits formed in the vertical direction, and a manual or electric drive device is disposed outside each of the guide members, and the driving device is passed through the slit. Since the driving device and the pressing portion are connected by a connecting plate communicating from the outside to the inside of the guide member, the pressing portion can be moved up and down from the outside of the guide member in which the pressing portion and the garbage bag are stored, There is an effect that it is possible to prevent the garbage bag from being broken by the movable member of the drive device during operation of the portion.

Further, a pressing portion is provided so as to be sandwiched between a pair of opposing guide members having slits formed in the vertical direction, and a manual or electric drive device is disposed outside each of the guide members, and the pressing member is inserted through the slit. The driving device and the pressing portion can be moved up and down by a connecting plate communicating from the outside to the inside of the guide member, and the pressing portion can be moved up and down from the outside of the movable member of the driving device when the pressing portion operates. There is an effect that it is possible to prevent the garbage bag from being broken by the movable member of the driving device during the operation of the pressing portion.

Further, at the standby position above the pressing portion, it opens parallel to the surface of the guide member in contact with the baffle plate attached to the guide member, and at other positions not in contact with the baffle plate at other positions. Since a pair of opening and closing bodies that are closed by the tension force of the tension spring are attached to the pressing portion via hinges, the opening and closing body is automatically opened when garbage is put in, and the garbage bag penetrates from the garbage inlet to the garbage bag. This has the effect of making it possible to put refuse, and when the refuse is compressed, the opening / closing body is automatically closed, so that the waste in the garbage bag can be pressed by the lower surface of the garbage, The effect of facilitating charging and operation is obtained.

Further, since the opening / closing body of the pressing portion is configured as described above, there is an effect that switching between the time of dust injection and the time of compression can be performed only by moving up and down without using a complicated mechanism. As a result, it is possible to obtain an effect of providing a compact and highly reliable refuse compression device.
