BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport device used for transporting garbage from high-rise buildings and the like.

0002

[Background Art and its Problems] In office buildings that are becoming more and more high-rise these days, large amounts of various types of garbage such as various papers, non-combustible materials, garbage, kitchen waste, etc. are disposed of in large quantities from each floor.
There is a need for a method to separate and collect them.

[0003] Conventionally, methods for transporting trash in such high-rise buildings include a method in which trash is collected by directly throwing it into a dust chute that penetrates the building vertically, and a method in which trash is collected by directly collecting it in a dust chute that penetrates the building vertically.As shown in FIG. A typical method is known in which a dedicated elevator 31 is installed and the garbage storage container 32 is transported by the elevator 31.

However, in the case of the dust chute method, the dust thrown into the chute is allowed to fall under its own weight, so the higher the building is, the more the impact noise caused by the falling becomes a problem. In particular, when bottles, cans, etc. are mixed in with the garbage, there is a problem in that a loud falling sound is generated. Another drawback is that it is difficult to separate and collect the garbage because the garbage is thrown in in a mixed state.

[0005] On the other hand, the elevator system can eliminate the drawbacks of the dust chute system as described above, but normally the size of the elevator for garbage inside a building is as small as possible in order to save space. Because of this limitation, the number of garbage storage containers 32 that can be transported in one up/down movement of the elevator 31 is often limited to one or two, as shown in FIG. For this reason, it takes a long time to transport the garbage, and the collection efficiency is poor.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a garbage conveying device that can separate and collect garbage without causing impact noise caused by dropping, and can efficiently convey a large amount of garbage in a small space. There is.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a lifter that is movable up and down on an elevator shaft that vertically passes through a building, and a holder for a garbage storage cart attached to the lifter. In addition to providing a plurality of them in the vertical direction, the structure has a garbage inlet facing the elevator shaft.

[0008] In the above structure, the holder of the garbage storage cart is formed to be able to rise and fall freely toward the garbage inlet, and a cart delivery stand that is able to be raised and lowered toward the lifter is provided at the garbage inlet. You can do it like this.

[0009]

[Operation] In the above structure, a plurality of garbage storage carts are attached to one lifter in the vertical direction via holders, and the lifter is moved up and down to transport each cart at a time. By increasing the number of carts that can be transported by one lifter, transport efficiency can be improved without taking up space.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 4 show a garbage conveying device according to an embodiment. In FIG. 1, reference numeral 1 denotes an elevator shaft that vertically passes through the building, and garbage entrances and exits 3 are provided at the intersections of the elevator shaft 1 and each floor 2a, 2b, 2c, . . . .

Each garbage entrance/exit 3 is provided with a shutter 4 or a door for opening/closing, and at the lower end of the entrance/exit 3, a cart delivery system is provided which is raised and lowered from a horizontal position to a vertically downward direction by the drive of an electric cylinder 5. A stand 6 is attached.

Inside the elevator shaft 1, two passages 8, 9 are formed by three guide rails 7a, 7b, 7c extending in the vertical direction. A lifter 11 is provided movably via moving rollers 10.

A counterweight 13 is movably housed in the other passage 9 via a drive device 12 such as a hoist that drives the lifter 11, making it easy to move the lifter 11 up and down.

On the other hand, a plurality of cart holders 14 are attached to the side surface of the lifter 11 facing the garbage inlet/outlet 3 at predetermined intervals in the vertical direction. As shown in FIGS. 2 and 3, this cart holder 14 is equipped with an electric cylinder 15.
The fork 1 rises and falls toward the garbage entrance 3 due to the drive of the
6 and a hook 18 whose tip end is always urged downward by the elastic force of a spring 17, and the cart is supported horizontally by a fork 16 inserted into the underside of the cart 20.
The upper end of the frame of the cart 20 is gripped by the hook 16 to hold the cart. Note that 19 is an operating lever for raising the hook 16.

Further, the garbage storage cart 20 for separately collecting garbage on each floor is formed by mounting a storage container 23 made of cloth, resin, or stainless steel on frames 21 and 22 that are foldably combined. and frame 21,
Wheels 24 for running are attached to the lower end of 22.

FIG. 4 shows an example in which the garbage conveying device of the embodiment is applied to a garbage separation collection system. A conveyor 25 for conveying the cart 20 is connected to the conveyor 25, and a rail 27 on which a cart 26 can run is connected to an end of the conveyor 25.

A plurality of garbage compactors 28 for storing garbage in a compressed state are arranged along the above-mentioned rail 27, and between each garbage compactor 28 and the rail 27, A cart reversing device 29 is provided for raising and lowering the cart 20 and reversing it toward the hopper of the trash compactor 28. Note that 30 is a return conveyor for returning the empty cart 20 to the garbage entrance/exit 3'.

This embodiment has the structure as described above, and its operation will be explained next. As shown in FIG. 1, when a plurality of carts 20 containing various kinds of paper, non-combustible materials, garbage, kitchen waste, etc. are carried to the garbage entrance 3 of a predetermined floor, a worker operates the lifter call switch.

As a result, the cart transfer table 6 at the garbage entrance/exit 3 stands up and becomes horizontal, and the lifter 11 ascends to the calling floor. In this case, the forks 16 of the holder 14 are laid down to prevent interference with the cart delivery table 6.

When the uppermost holder 14 of the lifter 11 rises to the garbage inlet/outlet, the lifter 11 is stopped and the fork 16 of the holder 14 is raised to a horizontal position by driving the electric cylinder 15.

Next, open the shutter 4 of the garbage entrance 3,
An operator pushes the cart 20 and sets it on the holder 14. Next, the lifter 11 is raised to a position where the second holder from the top faces the garbage inlet/outlet 3, and the next cart is set on the horizontally erected fork 16. By repeating the same operations as described above, the cart 20 is set in each holder.

When the carts 20 are held by all the holders 14 (at this time, a lifter full signal may be issued), the operator operates the lifter lowering switch. As a result, the cart transfer table 6 of the garbage entrance/exit 3 is laid down, and the lifter 11 is lowered. Each lowered cart 2
0 is the garbage entrance 3' at the bottom of the elevator shaft 1
The garbage is sequentially taken out onto the conveyance elevator 25, and stored separately in each garbage compactor 28 according to the type of garbage stored therein.

On the other hand, in order to return the empty cart 20 to each floor, the empty cart 20 is first set on the lifter 11 that has descended via the return conveyor 30, and then the empty cart 20 is placed on the lifter 11.
to the cart loading floor. In this case, lifter 1
The lifter 11 is raised to a position where the lowest cart 20 faces the garbage entrance/exit 3.

Next, the cart transfer table 6 of the garbage entrance/exit 3 is erected horizontally, the shutter 4 is opened, and the empty cart 20 is taken out from the holder 14 at the lowest stage.

[0025] Next, the lifter 11 is lowered in stages at intervals of each holder 14, and the carts are removed one by one. When the cart removal is completed, the shutter 4 is closed, and the fork 16 and cart delivery table 6 are folded.

Note that in the above structure, the cart delivery table 6 can be omitted. Further, the holder may have a structure that simply suspends and holds the cart.
