Description

The present invention is discharged at home about the trash waste (garbage).

  Conventionally, waste discharge is a lifetime, but in the process of discharge, recovery, combustion, and landfill, during discharge and recovery, it is collected manually in garbage bags and bound by human power. It is made up. However, artificial storage is unsanitary, and there is a limit to the sealing with human power, and a bad odor is emitted to the surroundings. Also, taking out the trash bag from the trash can put a heavy burden on those who are weak.

And since the size of the garbage bag is fixed in the collection of waste in the bag-shaped garbage bag, if the waste is a small amount, put it in a small-sized bag, and then put it again in a fixed-size garbage bag. It was. For this reason, a garbage bag is used twice and it is uneconomical. If a small amount of trash is put into a large trash bag and the trash is put up to that size, it will give off a foul odor and will cause spoilage and breeding of pests, making it extremely unsanitary.
In the case of a large amount, it is necessary to prepare a larger bag or to sort.
And since the collection of waste is regular, it must be stored for a certain period of time in a general household, and during that time, corruption proceeds.

  A manual bag-shaped garbage bag required a force to seal it. And manual sealing of garbage bags is unsanitary.

  In Patent Document 1, in order to solve the problem that it is difficult for an elderly person or the like to close the opening portion of the garbage bag, an adhesive portion is provided on the upper edge of the opening portion of the garbage bag, thereby opening the opening portion. A garbage bag that is closed by bonding is disclosed.

Further, Patent Document 2 discloses an apparatus that forms a garbage bag by thermally pressing a cylindrical film and pressing the center of a thermocompression bonding portion for dust such as diapers.
JP 2004-366818 A JP 2002-337802 A

  In the method described in Patent Document 1, since the opening of the garbage bag can be bonded, it is not necessary to manually bind the upper part of the garbage bag. However, in the method described in Patent Document 1, since the size of the garbage bag is constant, it becomes uneconomical and unsanitary depending on the amount of garbage and the collection cycle. Furthermore, it is not possible to reduce the load of the operation of attaching the garbage bag to the trash box or the operation of taking out the garbage bag when collecting the garbage.

  In the method described in Patent Document 2, dust can be handled in a sanitary manner by forming a bottom on a cylindrical sheet by thermocompression bonding and forming an upper portion by thermocompression bonding immediately after the dust is introduced. However, a technique for accumulating individual garbage bags sealed by thermocompression bonding for business use is disclosed. This makes it difficult to sanitize trash and has a heavy workload. For this reason, the method described in Patent Document 2 cannot reduce the workload during the garbage disposal operation. In addition, a double garbage bag is required to throw away individual garbage bags.

  In addition, there is a commercially available trash box for household use that uses a cylindrical sheet and is sealed by twisting or thermocompression to prevent the generation of bad odor and to handle hygienic handling. However, these trash cans only accumulate trash bags in the form of a wiener, and when they are discarded, a separate trash bag is required.

  In each of the above conventional examples, a small amount of dust is immediately sealed and cannot be collected for collection as a garbage bag. That is, it must be kept indoors until a certain amount of garbage is accumulated. Therefore, in terms of hygienic handling, it is incomplete, limited and can also give off odors. In addition, it is not possible to reduce the labor required for collecting garbage bags.

  In addition, since how garbage is generated varies depending on the life cycle, there are cases where it is desired to throw away garbage in a small amount and cases where it is desired to throw away a large amount of garbage. A certain size garbage bag cannot cope with this change, and it is uneconomical to use a large garbage bag when throwing a small amount of garbage. Shopping bags from stores such as supermarkets and convenience stores are often used for throwing away trash. This is thought to be due to the usage of throwing away a small amount of garbage or keeping it sealed. If this small amount of garbage cannot be thrown away economically and hygienically, it will eventually hinder activities such as bringing shopping bags.

  As described above, trash disposal is a lifelong work, and if the work load of trash disposal once is alleviated, the burden of household chores throughout life will be greatly reduced.

  An object of the present invention is to provide a trash can that is hygienic, economical, and has low work effort.

The present invention includes an opening 1 at the top of the trash box, a main body 4 having a movable bottom surface 7 for supporting the bottom of the trash bag 2 in the hollow of the trash box, the opening 1 and the slidable arrangement with the main body . The trash bag storage unit 3 and the trash box are installed in a hollow space to seal the trash bag, and when the trash is thrown away, the trash bag storage unit 3 and the main body 4 are opened to open the main body 4 and cut the trash bag. Sealing cutting means 10, and movable bottom surface driving means 14 for operating the movable bottom surface 7 so that the position of the bottom of the garbage bag 2 can be adjusted from the uppermost height 50 to the lowermost height 53 of the main body 4. It has the structure of having.
Thereby, the said subject is solved.

The opening 1 is an entrance for introducing garbage. The garbage bag storage unit stores unused garbage bags and sequentially sends them out. This storage part may be in the upper part of the main body, or may be the lower part of the main body (in the lower part, there may be a garbage bag feeding roller).
The sealing and cutting means 10 may include means for sealing the garbage bag by pressure bonding (for example, thermocompression bonding means) and cutting means such as a cutter. As sealing, in addition to thermocompression bonding, an adhesive or the like can be used. Further, in order to prevent leakage from the garbage bag, the length of the crimping may be adjusted, and the number of crimping may be two or more. Further, as a means for sealing, a method of sealing the garbage bag from two opposite directions or a method of pressure bonding from four directions orthogonal to each other may be adopted. In addition, a general method for wrapping garbage bags can be employed.

Sealing cutting means 10 cuts the waste bags by sliding the garbage bag storing portion 3 and the body 4.
The movable bottom surface supports the bottom of the garbage bag, and moves the bottom of the garbage bag up and down in the range from the uppermost height 50 to the lowermost height 43 of the main body 4 . For this reason, it is possible to lift it a garbage bag on top by both the configuration of the lifting of the sealing cutting means and garbage bags. Furthermore, it is possible to perform control to ensure economic efficiency and reduce work labor at the time of throwing in garbage, at the time of throwing away garbage, and at the time of preparation.
For example, when throwing in and throwing out trash, the height of the trash bag can be made variable (economical). And when throwing away a garbage bag, the operation | work which lifts a garbage bag is automated (work effort reduction).

According to the trash box of the present invention, as described above, since the movable bottom surface is driven, it is possible to perform control for reducing economy and work labor at the time of trash input, trash disposal operation, preparation, etc. Become.
For example, the invention according to each claim and the invention described in the embodiments have the following effects.
If the height of the garbage bag can be adjusted, the garbage bag can be used economically.
If it can be lifted during the garbage disposal operation, the work effort can be reduced.

  In addition, it is not necessary to replace the garbage bag again and again by performing only the initial work, and a full operation is automatically performed from the bag generation, sealing, cutting, and preparation of the next garbage bag.

  When the capacity of a conventional general household waste bin increases, it is necessary to bend the body when removing the garbage bag when discharging, and it will be lifted up. Cannot be done. In this regard, according to the present invention, since the movable bottom surface lifts the garbage bag, the operator does not need to perform the removal operation.

  As described above, the trash can according to the present invention can handle trash in a sanitary and economical manner, and can significantly reduce the work labor.

As shown in FIG. 1, a trash can according to an embodiment of the present invention includes an opening 1 at the top of a trash can, a main body 4 having a movable bottom surface 7 in the trash can hollow, and a trash bag storage having the opening 1. 3 and the sealing / cutting means 10 installed in the inside of the trash can, the trash bag is sealed, cut, and taken out automatically in a fully automatic manner.
The same applies to the rectangular trash can shown in FIG.

In this embodiment, since the movable bottom surface 7 moves up and down, the height of the garbage bag can be adjusted, and it can be used economically. Moreover, since the height of a garbage bag can be determined arbitrarily, it can be used economically without reinserting.
Further, by making the garbage bag a cassette type, it is possible to reduce labor for attaching and detaching the garbage bag to and from the housing many times.

  In the example in which the movable bottom surface 7 is detachably mounted, the trash can can be easily cleaned. In the example shown in FIGS. 1 and 2, the movable bottom surface 7 includes a movable bottom surface body 6 and a removable bottom surface packing 5. By making the bottom surface packing 5 removable, the movable bottom surface can be attached and detached. As described above, the movable bottom surface 7 is composed of the bottom surface packing 5 and the movable bottom surface body 6, and the bottom surface packing 5 can be removed even when it is used and becomes dirty by being detachably equipped. So you can keep it hygienic.

  In addition, the trash box may include a trash disposal controller 11 that receives an instruction of a trash disposal operation and a notification unit 12. In this example, the garbage disposal controller 11 includes a process of moving the movable bottom surface 7 down when receiving an instruction of the garbage disposal operation, and a process of moving up after notification of completion of thermocompression bonding by the notification unit 12. Good.

In this example, the sealing and cutting means 10 is provided with a thermocompression bonding means (peeler) 9, and the peeler 9 of the garbage bag 2 by the movable bottom surface 7 guided on the movable bottom surface drive guide 15 during the garbage disposal operation. Since the garbage bag 2 is pressure-bonded by heat at an arbitrary height, the garbage bag can be completely blocked and sealed, and malodors and germs that are generated by manual binding can be suppressed.
And by providing the garbage disposal controller 11 which receives the instruction | indication of garbage disposal operation, since the process which raises the said movable bottom surface 7 automatically is performed, a user's workload can be reduced significantly.

  In addition, since the notification unit 12 is provided on the upper portion of the main body 4, the completion of the thermocompression performed inside the main body 4 is notified without opening the main body 4, so that it can be safely processed.

  Cylindrical vinyl can be adopted as the garbage bag 2. It is also possible to use vinyl with a handle.

  FIG. 3 is a use case diagram of this embodiment. The trash can according to the present embodiment fulfills a certain function, and is effective for various parties.

For waste collectors, when collecting waste, it can be economically collected without considering the size of the garbage bag, and when discharging, it can be sealed hygienically without getting your hands dirty, and it can be removed. Therefore, it is possible to work easily, and after that, it is possible to safely and automatically change the garbage bag without touching it.
Moreover, since it is sealed, it can be maintained for a long time without generating malodor. Depending on the material of the trash bag, it is possible to select a material that melts and changes its nature naturally, or a material that can safely seal and transport dangerous materials.

  For the collector, when collecting the garbage bag, there is no worry of unfastening the fastening portion, and therefore, the bad odor is suppressed and the handle is sufficient, so that the work efficiency is improved.

  For the processor and the environment, it is possible to reduce pollutants during combustion by reducing garbage bags or using materials.

  For producers and sellers, production and sales can be continued due to diversification or consumption of garbage bags.

  A first embodiment of the present invention is shown in FIGS. 4 to 14 are circular trash cans, and FIGS. 15 and 16 are rectangular trash cans. 4 to 14 exemplify a circular trash can, the relationship between the waste (trash) and the trash can and the basic operation are the same as those of the rectangular trash can.

  As shown in FIG. 4, the trash can according to the first embodiment includes an opening (for example, a lid) 1, a trash bag storage 3, and a main body 4. The trash bag storage unit 3 includes a storage unit lid 31 that opens and closes when the trash bag 2 is mounted, and a trash bag holder 32 that holds the trash bag 2 and feeds out the trash bag at the top. The upper surface of the storage lid 31 is equipped with a lamp 12 as a notification means and a garbage disposal button 13 for receiving an operation of the garbage disposal operation. The garbage bag storage unit 3 includes a cutter 8B (a part of the sealing and cutting means 10) on the inner side surface of the garbage bag storage unit 3 below the garbage bag holder 32.

  The main body 4 includes a sealing cutting means 10, a movable bottom surface 7, and a movable bottom surface driving means 14. The sealing and cutting means 10 includes a cutter 8A disposed at a position intersecting the cutter 8B at the inner upper end of the main body 4, and a thermocompression bonding means (peeler). The thermocompression bonding means 9 includes, in a circular trash box, a peeler 9 having a heating element, a peeler support 21 that supports the peeler and moves it to a crimping position, and a peeler driving means 18 that drives the peeler support 21. I have.

  The peeler driving means 18 includes a peeler support frame 22 that holds the peeler support 21 in a pressure-bonding position (not shown, and may be disposed on a side surface of the main body 4 parallel to the drawing), and the peeler support 21 in the normal state. 4 Standing on the inner side surface, a peeler drive guide 19 for guiding the peeler support 21 to the crimping position during the thermocompression operation, a peter drive roller 20 for operating the peeler support 21 in accordance with control by the garbage disposal controller 11, and this peter A feed-out mechanism 23 that guides the vertical movement of the base portion of the peeler support 21 according to the rotation of the drive roller 20 is provided.

When the peeler driving roller 20 rotates, the peeler support 21 moves in the vertical direction in FIG. This movement is regulated by the peeler drive guide 19 and the peeler 9 reaches the crimping position. The heating element may be provided only in the peeler 9 on the right side in FIG. 4 and the left side may assist crimping. Since the peeler support 21 is bent upward and inward, it draws a locus as shown by a two-dot chain line in FIG. With this trajectory, the cylindrical and hollow garbage bag 2 is stably brought in, and then crimped. In addition, with this trajectory, first, even when waste is thrown in a larger amount than usual, it is easy to return to the position shown by the solid line in the figure, and secondly, it acts to push waste into the trash bin, Thirdly, the upward movement of the peeler driving roller 20 can be converted into a pressing force between the peelers 9 by slightly tilting the tip of the peeler. Further, the peeler 9 on the right side in the drawing may have a convex portion at both ends in the normal direction in the drawing and a concave portion on the left side. Thereby, the adhesion surface in a crimping position can be stabilized, and a garbage bag can be brought close to a crimping position.

  The peeler 9 is normally stored in a trash can hollow (shown by a solid line), and can be moved during a garbage disposal operation. ).

  The movable bottom surface driving means 14 is disposed at the lower side of the movable bottom surface 7, and is movable according to the rotation of the movable bottom surface driving roller 16. A movable bottom surface drive guide 15 for guiding the vertical movement of the bottom surface 7 is provided. For example, four (15A to 15D) movable bottom surface drive guides 15 may be installed in the main body 4 (FIG. 14 for a circular trash can and FIG. 16 for a rectangular trash can).

  Reference numerals 50 to 53 are position names indicating positions in the height direction of the main body. This position includes the uppermost height 50 at which the movable bottom surface is guided upward, the thermocompression-designated height 51 that is the height of the pressure bonding position of the peeler 9, and the movable bottom surface 7 at the lowest position when the waste is charged. The maximum allowable height 52 that can be positioned, and the lowest height 53 when the movable bottom surface is guided to the lowest position during the dust disposal operation.

  As shown in FIG. 5, when the peeler 9 reaches the crimping position and is thermocompression bonded, a dust bag fastening portion 24 is formed. This is the bottom of the garbage bag. When the bottom of the garbage bag is formed, waste can be input. At the start of charging, the movable bottom surface 7 is positioned slightly below the specified thermocompression bonding height 51. In this state, it becomes a “small” garbage bag. When the peeler 9 is operated in the state shown in FIG. 5, a “small garbage bag” can be formed.

  The movable bottom surface 7 can be arbitrarily moved up and down from the uppermost height 50 to the maximum allowable height 51 by the user operating the up / down pedal 17. Arbitrary vertical movement up to the top 50 is very convenient, for example, for checking whether an object has been thrown away by mistake. Further, when the height of the garbage bag is extended according to the amount of waste input (movable bottom surface 7 is moved downward), it is possible to make the input using the maximum capacity of the garbage bag.

  As shown in FIG. 6, the movable bottom surface is freely driven, and waste can be collected up to the maximum allowable height 52. The length from the maximum allowable height 52 to the lowermost height 53 is set according to the height of the garbage bag storage unit 3. In other words, even if waste is packed into the hollow portion of the garbage bag storage unit 3, the movable bottom surface 7 is moved down from the reference numeral 52 to the reference numeral 53, so that the garbage bag is placed on the upper part of the garbage bag at the specified thermocompression bonding height 51. A fastening part can be formed.

  As shown in FIG. 7, when the waste disposal control is started by operating the waste disposal button 13 after the introduction of the waste, the movable bottom surface 7 is lowered by the length of the dust bag sealing portion. Then, the thermocompression-bonding means peeler 9 is driven from both directions to the center, and the thermocompression-bonding is performed. This is the upper part of the garbage bag. This throw-away control can be operated only when the opening (lid) 1 is closed and the garbage bag storage 3 is coupled (locked) to the main body by providing an open / close sensor such as a lid. .

  As shown in FIG. 8, the garbage bag fastening portion 24b is automatically formed by thermocompression bonding. The garbage bag fastening portion 24b automates the manual operation that normally binds the garbage bags. The garbage bag fastening portion 24a at the lower part of the garbage bag is formed at the start control or preparation control (FIG. 13) shown in FIG. When the thermocompression bonding is completed, the notification device 12 notifies the completion of the thermocompression bonding, and the garbage bag storage unit 3 can be slid. Various sensors and roles that should be equipped will be described in Example 3.

As shown in FIGS. 9 and 10, in the present embodiment, the trash bag storage unit 3 is slidably mounted on the main body 4, and the trash bag is cut by the slide of the trash bag storage unit 3. In this embodiment, the garbage bag storage unit 3 twists the thermocompression-bonded garbage bag by the sliding operation, and the cutter 8 cuts the twisted garbage bag by the sliding operation.

  9 and 10 is rotated counterclockwise in FIG. 10 to the position of FIG. 10 by the rotating shaft 30 shown in FIG. 9 and FIG. 10, the cross section becomes as shown in FIG. On the right side in FIG. 9, the cutter 8A of the main body 4 and the cutter 8B of the garbage bag storage unit 3 sequentially intersect, and the garbage bag is cut by the intersection of the cutters 8A and 8B.

  By the rotation of the garbage bag storage unit 3, the garbage bag that has been thermocompression bonded at the top is twisted further above the thermocompression bonding position and wound around the positions of the cutters 8A and 8B. In the example shown in FIG. 10, the reference numeral 2 b of the garbage bag has already been cut, and the reference numeral 2 a is further cut by rotating the garbage bag storage 3.

As shown in FIG. 11, when the dust bag is cut, dump controller 11, depending on the position of the dust bag storage portion 3, the movable bottom 7 is driven to the top level 50, an auxiliary of the garbage bag extraction I do. In the state shown in FIG. 11, the garbage bag storage unit is located behind the main body 4 and the upper portion of the main body 4 is released. This thermocompression bonding, cutting, and garbage bag taking out assistance are one of the advantages of this embodiment, and the user is freed from the work of approaching and lifting up the garbage bag clogged with open waste.

  Further, by moving the movable bottom surface 7 up and down, the user can arbitrarily adjust from a small garbage bag to a large garbage bag, and in order to assist the removal of the garbage bag, the garbage bag can be easily and lightly used. It is possible to throw away garbage (carry the garbage bag to the garbage collection point). In this embodiment, the garbage bags are not accumulated in the form of a wiener or the like, but are automatically cut after thermocompression bonding and conveyed upward to assist with taking out. It is possible to dispose of garbage without waste of vinyl in the collection cycle.

  As a garbage collector, an appropriate amount of garbage is taken out during the garbage collection cycle, and garbage bags that enclose a large amount of accumulated wiener-like waste are not aperiodically taken out. Leveled. Also, since there is no double use of vinyl, such as using a large garbage bag to take out a small amount of garbage, or enclosing a sealed item in a small garbage bag in a larger garbage bag, the amount of vinyl to be burned is appropriate. , Can reduce the total amount.

  Also, in this example, when biodegradable plastics are used, only garbage and necessary materials are input, and garbage bags are formed according to this example, the generation of bad odors in the neighborhood when buried in the soil, etc. Is easy to use as garbage disposal.

  As described above, the trash can according to the present embodiment not only greatly reduces the burden of housework such as trash disposal and trash removal, but also has an advantageous effect on the collector and the global environment.

  FIG. 12 is an explanatory diagram showing an example when the garbage bag storage unit 3 is returned to the normal position after the garbage bag is taken out, and FIG. 13 is a cross-sectional view showing an example of the preparation operation. Details of this will be described later as a second embodiment. In the example shown in FIGS. 11 to 13, after the garbage bag is cut, a preparation operation for forming the next garbage bag (fastening the garbage bag as the bottom of the next garbage bag is performed. Part formation) is also automated. However, once the garbage bag is taken out, the operator can manually perform the preparation work by gripping the end portion of the garbage bag by hand and hooking it on the locking portion 41 shown in FIG.

  The slide will be described again with reference to FIG. FIG. 14 is a plan view corresponding to FIG. In the figure, the main body 4 is equipped with a cutter 8A on the upper right, and the garbage bag storage unit 3 is equipped with a cutter 8B on the lower left. When the garbage bag storage unit 3 is rotated in the counterclockwise direction in the drawing by the rotation shaft 30, the cutters 8A and 8B intersect and are cut.

  The main body 4 includes a movable bottom surface 7 and movable bottom surface drive guides 15A, 15B, 15C, and 15D for guiding the vertical movement of the movable bottom surface 7. The movable bottom surface drive guide 15 group is preferably arranged at a position where it does not cross the peeler 9. The peeler 9 has uneven portions at the upper and lower ends in FIG. The concavo-convex portions mesh with each other on a straight line passing through the rotation axis 30 in the drawing and parallel to the peeler 9. By this uneven part, prior to the thermocompression bonding of the garbage bag, the garbage bag can be satisfactorily brought closer. The peeler 9 moves from both directions to the center, and is combined and thermocompression bonded by generating heat at a constant temperature for a certain time.

  15 and 16 are diagrams illustrating an example of a rectangular trash can. As shown in FIG. 15, in the rectangular trash can, the main body 4 may include a peeler transfer mechanism 60 that transfers the peeler 9 from the inner side surface of the main body 4 to the thermocompression bonding position. In this example, the peeler drive guide 15 is disposed so as not to exceed the upper end of the peeler transfer mechanism 60. The main body 4 includes an L-shaped cutter 8C, and the garbage bag storage unit 3 includes an L-shaped cutter 8D that intersects the cutter 8C. Further, since the main body is rectangular, the movable bottom surface 7 is also rectangular.

  The rectangular trash can shown in FIGS. 15 and 16 also has the same effects as the circular trash can described above.

The order of use of circular and rectangular trash cans will be described.
a. The user sets the garbage bag 2 in the garbage bag storage unit 3.
b. The user pulls out the first vinyl from the garbage bag 2 to the inner wall side of the main body 4.
c. The user opens the opening 1.
d, the user locks vinyl of b to the locking portion 41 of the movable bottom surface 7 inside the main body 4.
e. The user closes the opening 1.
f. The user operates the garbage disposal operation means (trash disposal button) 13.
g, The garbage disposal controller 11 drives and controls the thermocompression bonding means (peeler) 9 to form a garbage bag fastening portion 24.
h. The user puts waste into the garbage bag fastened with g through the opening 1.
i. The user arbitrarily operates the movable bottom surface 7 with the upper and lower pedals 17.
j, the user closes the opening 1;
k, the garbage disposal operation means (trash disposal button) 13 is operated.
l, The garbage disposal controller 11 drives and controls the thermocompression bonding means (peeler) 9 to generate a garbage bag fastening portion 24 at the upper part of the garbage bag.
m, the garbage disposal controller 11 notifies the completion of the crimping by the notification means 12.
n. The user slides / rotates the garbage bag storage 3. By this slide, the cutter 8A and the cutter 8B cut the garbage bag completely fastened by 1.
o, The movable bottom surface 7 is moved up to the top by the up / down pedal 17 or automatically.
p. The user takes out n garbage bags from the top of the main body 4.

  As described above, according to the first embodiment, the height of the garbage bag can be arbitrarily adjusted by moving the movable bottom surface 7 up and down, and the thermocompression bonding means crimps the garbage bag to form upper and lower fastening portions. Since the cutter 8 cuts the upper part of the garbage bag, it is possible to form and use a garbage bag of the minimum necessary size (height) according to the amount of waste, from a small garbage bag to a large garbage bag, Furthermore, since the movable bottom surface moves upward, the waste is input and the work of taking out the sealed garbage bag is assisted, so that the work load of the waste handling can be reduced. Thus, it is possible to provide a trash can that is economical, hygienic, and can further reduce the work load by optimizing the amount of vinyl used, thermocompression bonding at any timing, and vertical movement of the movable bottom surface. it can.

Next, a trash can that automates the preparation operation using the entraining unit 40 and the locking unit 41 will be described as a second embodiment.
Referring to FIG. 4 again, in this embodiment, the garbage bag storage unit 3 has a storage holder 32 for holding the garbage bag 2, and the twisted garbage bag is disposed on the lower surface of the storage holder 32. Is provided. And it has the projection part 42 which supports the bottom part side surface of the said garbage bag in the side edge of the said movable bottom face 7, The said waste bag is put into the projection part 42 of the said movable bottom face 7 below the said winding part 40. A locking portion 41 that is received from the winding portion 40 and locked to the movable bottom surface 7 is provided.

  Referring to FIGS. 8 to 10 again, the winding portion 40 includes a winding portion 40A in the vicinity of the rotary shaft 30 and a winding portion 40B disposed in the vicinity of the cutter 8B (directly above the locking portion 41). When the garbage bag storage unit 3 is slid (rotated) from the state shown in FIG. 8, in the positional relationship shown in FIG. 10, as shown in FIG. 9, the entrainment unit 40B is a garbage bag cut by the cutters 8A and 8B. Entrain and hold 2b. As shown in FIG. 10, the entrainment part 40 </ b> B holds the cut garbage bag 2 b so that it does not hang down into the hollow of the main body 4. This holding is performed by being naturally caught in the entrainment part by the rotation of the garbage bag storage part 3. Further, the entraining portions 40A and 40B also play a role of guiding the garbage bag to the cutters 8A and 8B.

  Referring to FIG. 11 again, the entrainment unit 40B holds the residue of the completely cut garbage bag on the garbage bag storage unit 30 side. After taking out the trash bag, the trash bag 2a is held even during a slide for returning the trash bag storage unit 30 to the normal state.

Referring to FIG. 12 again, when the garbage bag storage unit 30 reaches the normal state, the entrainment unit 40B is located immediately above the locking unit 41. Then, when the movable bottom surface 7 is moved to the topmost height, the locking portion 41 locks the garbage bag 2c in association with the entraining portion 40B (the same applies to the rectangular trash box shown in FIG. 15). When the locking part 41 locks the garbage bag 2 c, the movable bottom surface 7 is moved below the thermocompression-designated height 51. This state is indicated by a two-dot chain line. Since the locking part 41 positions the garbage bag below the thermocompression-designated specified height 51, the thermocompression-bonded garbage bag 2 d becomes the garbage bag fastening part 24 when thermocompression bonding is performed in this state. The garbage bag in this state is indicated by a dotted line.
After the thermocompression bonding, the locking portion 41 releases the locking of the garbage bag 2c. Further, it may be locked until dust disposal control. In this case, the garbage bag is sent out when the movable bottom surface 7 is moved down regardless of the input of the waste.

  As described above, according to the second embodiment, it is possible to automate the preparatory operation until the next use after throwing away the dust by the cooperation of the winding portion 40 and the locking portion 41. Moreover, the winding part 40A, 40B can be realized by a mechanism by arranging the winding parts 40A and 40B at a position where the dust bag storage part 30 naturally winds. The holding may be switched between a holding state and a normal state according to the rotational position of the garbage bag storage unit 30. And also about the latching | locking part 41, it is made to switch a releasing state (lower moving bottom face of FIG. 13 upper part) and a locking state (lower moving bottom face of FIG. 13 center part) according to the position of a lower moving bottom face. It can be realized with a mechanism without using a motor or solenoid. About switching of the state of the winding part 40 and the latching | locking part 41, it is good to use a string spring or a leaf | plate spring.

Next, control of the trash box described in detail as the first and second embodiments will be described as a third embodiment.
The operation and control of the trash box are required when A: when a garbage bag is newly attached, B: when the height of the trash box is changed according to the input of waste, and C: when the trash bag is formed and taken out. Become.

  As described above, the trash can is provided with the trash bag storage portion 3 having the opening 1 into which the waste is charged, the main body 4 supporting the trash bag storage portion, and the body hollow so as to be movable up and down. A movable bottom surface having a locking part 41 for locking the tip of the garbage bag and a cylindrical garbage bag mounted on the garbage bag storage part 3 are sealed and cut inside the garbage bag storage part and the main body. A sealing cutting means 10, a movable bottom surface driving means 14 that drives the movable bottom surface up and down in response to reception of a vertical movement signal, and a dust disposal controller 11 that controls the movable bottom surface driving means 14 are provided.

  In this embodiment, the dust disposal controller 11 is moved down to the movable bottom surface driving means 14 when the tip of the garbage bag is locked to the locking portion 41 in relation to the drive control of the movable bottom surface 7. A preparation control 204 for inputting a motion signal to move the movable bottom surface to a sealing position, a discard control 201 for inputting a downward motion signal to the movable bottom surface driving means 14 when forming the garbage bag, and the sealing When the garbage bag formed by the cutting means 10 is taken out, a downward movement control 200 for inputting an upward movement signal to the movable bottom surface driving means 14 is provided.

  FIG. 17 is a robustness diagram of this embodiment. B: In order to change the height of the trash box in accordance with the input of the waste, the movable control 200 for moving the movable bottom surface 7 up and down is performed by operating the up and down pedal 17. The garbage disposal controller 11 inputs an upward movement signal or a downward movement signal to the movable bottom surface driving means in accordance with the operation of the upper and lower pedals 17. Thereby, the movable control 200 moves the movable bottom surface 7 up and down.

  Reference numeral 17 denotes a user interface. A symbol 200 is a control, and a symbol 7 is a resource (physical existence). In the robustness diagram (and actual control), the interface cannot directly control resources. Resources cannot cooperate directly with each other.

  A: A common control is required for newly installing a garbage bag and C: forming a garbage bag and taking out the garbage. Here, the discard control 201 for forming the garbage bag fastening portion 24 in the garbage bag and the preparation control 204 for preparing the next garbage bag after the garbage is taken out or at the time of new attachment are common. For this reason, the controls 201 and 204 are constructed, and the control for A and C is performed by the combination thereof.

  When the discard operation means (trash discard button) 13 is operated, the discard control 201 operates. The discard control includes a control for lowering the movable bottom surface 7 to pull out a garbage bag necessary for pressure bonding, a control 202 for driving the peeler 7 to thermocompression-bond the garbage bag, and cutting or cutting the garbage bag to the operator. A control 203 for urging, and a control for assisting the removal of the garbage bag by moving the movable bottom surface 7 to the uppermost height 50 after cutting.

  In the second embodiment, the preparation control 204 moves the movable bottom surface 7 upward to transfer the garbage bag from the entraining portion 40 to the locking portion 41, and moves the tip portion of the garbage bag to a position below the thermocompression specified height 51. A control 205 for lowering and a control 202 for driving the peeler 7 to thermocompression-bond the garbage bag are provided.

FIG. 18 is a flowchart showing the processing steps of the preparation control 204.
A: When a garbage bag is newly mounted, the garbage bag is manually locked to the locking portion 41. C: After the dust is taken out, the garbage bag is locked to the locking portion 41 by hand (Example 1) or automatically (Example 2). In order to confirm the state of locking to the locking portion 41, a sensor that detects a blocking light due to mechanical contact between the locking portion 41 and the garbage bag 2 or locking of the dust bag may be used. Further, the force required for the downward movement of the movable bottom surface may be detected by, for example, the current value of a motor that drives the movable bottom surface driving roller 16, and may be detected as being not locked when the force is less than a certain value. If it is set normally, the process proceeds to step S2. If there is an abnormality, the control is stopped (step S2), and the user is notified by the notification means 12 or the like (step S6).

  In step S <b> 2, the movable bottom surface 7 is moved to the lower part of the thermocompression-designated height 51. The downward movement of step S2 may be a predetermined fixed length, or may be a length corresponding to the input amount when a sensor for detecting the input amount of waste is provided. Moreover, when the load of the motor that drives the peeler driving roller 20 is high, the movable bottom surface may be moved downward assuming that the waste has been thrown to the crimping position.

  Subsequently, the garbage bag is thermocompression bonded using the peeler 9 to form the bottom of the garbage bag (step S3). Then, the operator is notified of completion (step S4). Thereby, the worker can start the input of the waste.

  FIG. 19 is a flowchart showing the processing steps of the discard control 201. When the operation button (discard button) 13 is operated, the length of the dust bag for thermocompression bonding is pulled out by moving the movable bottom surface downward (step S12). Subsequently, the peeler is driven to form the upper part of the garbage bag (step S13). Further, the user is notified of completion, and the user is prompted to cut the garbage bag by sliding the garbage bag storage unit (step S14).

  When the operator completes the cutting of the garbage bag, the operator operates the upper and lower pedals to move the movable bottom up. If a sensor is provided to detect whether the trash bag storage unit 3 and the main body 4 are in a normal state or being slid, the automatic operation after the trash bag storage unit 3 slides to the position shown in FIG. It is also possible to control the rise of the movable bottom.

  Further, when a lock mechanism for locking the garbage bag storage unit 3 and the main body at the normal position is provided, it is preferable that the lock is performed during the control (particularly, thermocompression bonding) operation shown in FIGS.

  In addition, if the movable bottom surface 7 is equipped with a weight sensor, the dust disposal control may be automatically started when a predetermined constant weight is reached. As a result, a garbage bag having a weight greater than or equal to a predetermined weight is not carried to the collection place.

  As described above, according to the present embodiment, by configuring the control separately from the discard control and the preparation control, it is possible to automate the work necessary for handling the garbage while reducing the logic required for the control.

  The present invention can be used for manufacturing and sales of trash cans.
