Abstract

PURPOSE:To reduce noise generation sources, simplify the structure, and reduce the facility cost by providing multiple running blocks with dust mounting buckets each having a reaction plate with an electromagnetically excited linear motor along an endless circulating rail suspended in a shaft. CONSTITUTION:When wastes and dust bags are mounted on a bucket 2 on the right side, the bucket 2 starts to be lowered by its weight. When the descent starts, a reverse-phase electric signal is output to a linear motor 10 from a control device to cause the reverse thrust, and a braking force is applied to the bucket 2. The bucket 2 is lowered at a nearly constant speed without being set to the free fall state, When it reaches the lower end of an endless circulating rail 1, a running block 3 is turned along the rail 1 toward the ascent side of the rail 1, thus the bucket 2 is turned downward, and the mounted wastes are dropped to a dust storage section at the lower section of a shaft 11. When the bucket 2 is separated from the lower end of the linear motor 10 and lowered, the reverse-phase electric signal output to the linear motor 10 is turned off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dust chute device suitable for vertically transporting waste, particularly in medium-to-high-rise or super-high-rise housing complexes.

[Prior art] Conventional dust chute devices in high-rise apartment buildings, etc.
Garbage disposal space that connects vertically across multiple floors of a building (
Garbage input ports are provided on each floor, following the shaft (which means a chimney-like space in a concrete building).
A garbage bag or the like is inputted through this input port, allowed to fall naturally, and disposed of into the garbage storage section at the lower part of the shaft.

[Problem to be solved by the invention]

However, in such conventional dust chute devices, as the number of floors of the building increases and the height increases, the potential energy of the garbage bag increases, and when it is dumped, the impact of falling into the garbage storage section at the bottom of the shaft becomes large. As a result, an impact sound was generated and reverberated, and the garbage bags burst and the garbage was scattered, causing inconveniences such as requiring a large amount of effort to remove the accumulated garbage and deteriorating the sanitary environment in the surrounding area.

In addition, pneumatic waste transport equipment was developed to avoid such inconveniences, but this equipment itself requires a large amount of cost, making it economically difficult to maintain in areas other than large-scale high-rise residential complexes. It's not common.

This invention has been made in view of the problems of the prior art, and aims to solve the above problems by providing a device that allows the dumped garbage to be guided and dropped by a garbage loading bucket without causing it to fall. The purpose is

[Means to solve the problem]

In order to achieve the above object, the present invention provides an endless circulation rail that is installed vertically over the required floors within a shaft provided as a garbage disposal space in a multi-story building, and that a plurality of reaction plates having reaction plates are installed along the endless circulation rail. Traveling blocks are connected by wire at predetermined intervals so as to be able to freely travel in circulation, and an induction linear motor for electromagnetically urging the reaction plate is provided at at least one force point of the endless circulation rail. Further, a dust chute device is provided in which a dust loading bucket is attached to the traveling block.

[Effect]

Since the present invention has the above-described configuration, when the user uses the device, the linear motor is energized by, for example, pressing the button of the garbage inlet on the floor.
A garbage loading bucket (hereinafter simply referred to as bucket) attached to a traveling block having a reaction plate is given thrust through the reaction plate, comes to the input port position, and stops. At this time, the stop position can be set by a known simple control device. Therefore, when the user loads waste into the bucket, the bucket begins to descend due to the weight of the waste, but when the bucket begins to descend, the control device outputs an electrical signal of the opposite phase to the linear motor, creating a reverse thrust. Gives braking force to Heke 7. Therefore, the bucket is not in a free fall state, but descends at a constant speed and reaches the bottom end of the endless circulation rail, and the traveling block turns along this rail and heads toward the upward rail. The bucket also swivels downward to dump the loaded waste into the garbage storage section at the bottom of the shaft. Then, at the same time that the bucket becomes unloaded, the reverse phase electrical signal output to the linear motor is turned off, and the device returns to its state when not in use.

〔Example〕

The present invention will be explained below based on the drawings. 1 to 3 are diagrams showing one embodiment of the present invention.

FIG. 1 shows a side view of the embodiment, and FIG. 2 is a sectional view taken along line AA in FIG.

An endless circulation rail l made of H-shaped steel or the like is installed in a shaft 11 provided as a garbage processing space in a mid-to-high-rise or super-high-rise apartment complex, and is vertically supported by a shaft wall 11a by a support member 15 as shown in FIG. It is placed in place. The endless circulation rail 1 has a plurality of traveling blocks 3 connected by wires 5, and a garbage loading bucket 2 is attached to the traveling blocks via a hinge 12. The wire 5 connecting the running blocks 3 is supported by a support arm 6 provided on the running block 3, and is wound around a sheave 7 at the upper and lower ends of the endless circulation rail 1 so as to extend along the endless circulation rail 1 in an endless manner. It is stretched. One wire 5 is stretched on both sides of the endless circulation rail 1.

Induction type linear motors 8 are disposed at one or more locations on the endless circulation rail. On the other hand, the traveling block 3 is in rolling contact with the endless circulation rail 1 via rollers 4, and a reaction plate 9 is attached. Here, the mounting position and size of the roller 4 are adjusted so that the gap between the reaction plate 9 and the linear motor 8 is about 1 to 20. The length of the linear motor 8 is set to be longer than the vertical distance between adjacent buckets. Furthermore, since the endless rail 0, which is the portion to which the linear motor 8 is attached, requires highly accurate flatness and dimensions, a machined member is used. If necessary, the linear motor will be installed not only on the bucket lowering side of the endless circulation rail but also on the empty bucket rising side.

Next, to drive the device having the above configuration, the linear motor is energized at a required timing by a control device (not shown), and the linear motor 8 applies a thrust to the traveling block 3 facing in front of the linear motor 8 via the reaction plate 9. Then, all the traveling broncs and buckets connected to the traveling block 3 by the wire 5 begin to move.

If the garbage bag is inserted when the bucket 2 passes through the input port provided in the shaft wall, the falling distance of the garbage bag to the bucket is small, so that no large impact is applied. Alternatively, it is easy to provide a control system in which a switch button is provided near the input port, and when this button is pressed, the linear motor is energized, the bucket comes to the input port position, and then stops.

Now, when waste or garbage bags are placed in the bucket on the right side of Figure 1, the bucket begins to descend due to its weight.
When the bucket begins to descend, a control device (not shown) outputs an electrical signal of opposite phase to the linear motor, producing a reverse thrust and applying braking force to the bucket.

Therefore, the bucket is not in a free fall state, but falls at a constant speed until it reaches the bottom end of the endless circulation rail 1, and the traveling block 3 turns along this rail, causing the endless circulation rail 1 to rise. At this time, the bucket 2 also rotates downward to drop the loaded waste into the waste storage section at the bottom of the shaft 11. Then, when the bucket 2 leaves the lower end of the linear motor 10 and moves down, the reverse phase electrical signal that was being output to the linear motor is turned OFF.

Also, although the linear motor can apply braking force to the traveling block by reverse thrust, it does not have a function to stop and fix the bucket, so when continuing to stop the bucket, the third
As shown in the figure, a fluid pressure cylinder 1 is attached to an endless circulation rail 1.
6 is provided, and a stopper arm 13 pivoted to this cylinder ROLAD is maintained in a horizontal position to support the running block 3.

In addition, when a bucket connected by a wire is moved on a vertically long endless circulation rail like this device, the driving force of the rotary drive motor is normally transmitted to the sheave that supports the wire at both the upper and lower ends. The thrust force is transmitted to the bucket via the sheave and wire, but in this case, frictional force is required between the wire and the sheave, so a mechanism is required to adjust the elongation of the wire and provide the desired tension on the wire. becomes. This embodiment does not require such a wire tensioning adjustment device.

[Effects of the Invention] As explained above, according to the present invention, (1) noise sources such as rotating motors, gears, hair rings, etc. are extremely small;
2) Since the mechanism is simple, there are fewer failures and equipment costs can be reduced; (3) a wire tension adjustment device is not required; and many other effects can be obtained.
