DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical transport device for transporting a load in a vertical direction, and more particularly to a vertical transport device for reducing a space of a transport path and smoothly discharging a load.

[0002]

2. Description of the Related Art In a high-rise building such as a condominium, a vertical conveying device for dust is sometimes installed in order to eliminate labor for manually discharging dust. The vertical transport system is known to be an elevator type that raises and lowers the transport chamber.However, the elevator system is heavy, requires a large installation space, and operates efficiently in response to discharge requests from each floor. Can not do it. The vertical transport device (Japanese Patent Application No. 11-187832, Japanese Patent Application No.
No. -194202) is a slat conveyor type in which slats (blades) or pallets (carriers) have flexibility. Flexible slats or pallets can be realized, for example, in a net.

[0003] A general slat conveyor has endless ropes circulated in the vertical direction at four corners of a vertical conveying path, and the slats are developed horizontally at predetermined height positions of the descending ropes. At the bottom of the vertical transport path, guide the front cable to the rear of the rear side of the vertical transport path and route the rear cable to the front at the lower end of the vertical transport path, and then attach the corners to the rear of the vertical transport path. The slats are guided to the rear side, and the rear slats are configured so that the empty slats are raised and raised. In addition, at the upper end of the vertical transport path, the slats are deployed horizontally again by guiding the front rope rising from the rear rear part to the front side and guiding the rear rope immediately downward. It is configured to be. When the slat conveyor is used for conveying garbage, the structure can be simplified as compared with the elevator, and the slats are provided for each floor, so that the discharge request from each floor can be satisfied immediately.

[0004] However, if an irregular soft garbage bag is placed on a rigid and horizontal member such as a pallet formed of a member or a pallet formed of a plate having limited deflection such as a slat, the garbage bag may fall off during transportation. There is a concern that it may protrude. Therefore, the present applicant has adopted a net as a load receiving member having remarkable flexibility. The load receiving net is formed by using a net having a marginal area with respect to the cross-sectional area of the vertical transport path, and the four corners of the load receiving net are supported by each of the ropes. Can be deployed horizontally. When a garbage bag is placed on the receiving net, the central portion of the receiving net is not supported at all, and sinks below the edge portion due to the load of the garbage bag. Therefore, the garbage bag does not fall off or protrude. However, if the rope is only stretched between the guide members at the upper and lower ends, when the load receiving net sinks due to the load of the garbage bag, the rope moves toward the center of the vertical transport path. In order to make it difficult to insert a garbage bag, horizontal bars for regulating the space between the cords are provided between the cords on the front side and between the cords on the back side. Further, a loading net can be attached to this horizontal bar.

Further, the present applicant has proposed a mode in which the lower end of the vertical transport path extends horizontally forward to the front side, and garbage bags are discharged from the horizontal extension section. We were considering a way to directly discharge garbage bags. These techniques will be briefly described as conventional techniques.

First, a vertical transport device having a horizontal extension portion
As shown in FIG. 8, endless ropes 1a, 1b, 1c, 1d circulating in the vertical direction are arranged at approximately four corners of the vertical transport path, and the descending ropes 1a, 1b, 1c, 1d are arranged. Each of the corners of the load receiving net 2 which is developed substantially horizontally at predetermined height positions is supported, and the ropes 1a, 1b on the front side of the vertical transport path are supported.
The front horizontal bar 3a and the rear horizontal bar 3b that regulate the space between the cables are inserted between the cables 1c and 1d on the rear side and between the cables 1c and 1d, and the front cables 1a and 1b are inserted at the lower end of the vertical conveyance path. It extends forward to the front side (horizontally extending portion) to a predetermined position, guides it from the front end to the rear side on the back side of the vertical transport path, and moves the ropes 1c and 1d on the rear side forward to the predetermined position on the front side. It is configured to extend and guide it from the front end to the rear of the rear side of the vertical transport path, and at the rear side of the rear side, an empty load receiving net (not shown) is raised almost upright. Further, at the upper end of the vertical transport path, the front ropes 1a, 1b rising from the rear rear part are guided to the front side, and the rear ropes 1c, 1d are immediately guided downward. Again, the slats are configured to be deployed substantially horizontally. The length of each of the ropes 1a, 1b, 1c, 1d is the same, and the ropes 1a, 1 on the front side at the upper end and the lower end.
The load receiving net 2 can be expanded substantially horizontally or substantially erected by the path difference between the b and the ropes 1c and 1d on the rear side. 4 is a guide member for guiding the cable in a desired direction. For example, the rope can be configured by a chain, and the guide member 4 can be configured by a sprocket wheel. Also, by appropriately setting the number and arrangement of the guide members 4, the front side ropes 1a and 1b and the rear side rope 1
c, 1d is locally formed, and the receiving net 2
Can be extended to a state without bending. For example,
In the horizontal extension portion and the rear portion on the rear side, the load receiving net 2 may be extended and moved.

The empty load receiving nets 2 located at the respective heights of the vertical transport path are expanded substantially horizontally in advance in a bent state. When the garbage bag 5 is placed on the load receiving net 2, the central portion of the load receiving net 2 sinks below the edge portion due to the load of the trash bag 5. When the ropes 1a, 1b, 1c, 1d are circulated in the vertical direction, the load receiving net 2 descends while being kept substantially horizontal in the middle of the vertical transport path, and moves horizontally to the front side at the lower end. Wrap around from the tip. At this time, the garbage bag 5 is discharged from the horizontal extension.

Next, as shown in FIG. 9, a vertical transport apparatus for directly discharging garbage bags from the vertical transport path is provided with endless ropes 1a, which are vertically circulated in approximately four corners of the vertical transport path. 1b,
1c and 1d are arranged respectively, and each cable 1a, 1 descending.
b, 1c, and 1d, each corner of the load receiving net 2 developed substantially horizontally at each predetermined height position is supported, and between the ropes 1a and 1b on the front side of the vertical transport path and the ropes 1c and 1c on the back side. The front horizontal bar 3a and the rear horizontal bar 3 for regulating the cable interval between 1d
b, and at the lower end of the vertical transport path, the front side ropes 1a and 1b are immediately guided from the front side to the rear side on the rear side of the vertical transport path, and the upper side ropes 1c and 1c, 1d
Once, and after passing through the lower end on the front side, it is guided to the rear of the back side of the vertical transport path, and at the rear side on the back side, an empty load receiving net (not shown) is raised almost upright It is configured to be. Also, at the upper end of the vertical transport path, the front ropes 1a, 1b rising from the rear rear part are guided to the front upper part, and the rear ropes 1c, 1d are immediately guided downward. , So that the slats are deployed substantially horizontally again. The length of each of the ropes 1a, 1b, 1c, 1d is the same, and the load receiving net 2 can be expanded substantially horizontally or substantially erected by the path difference between the upper end and the lower end. Also in this case, similarly to the previous example, by appropriately setting the number and arrangement of the guide members 4, the front side ropes 1 a, 1
The path difference between b and the ropes 1c, 1d on the rear side is locally formed, so that the load receiving net 2 can be extended without bending. For example, the load receiving net 2 may be extended and moved in the vicinity of the lower end of the vertical transport path or in the rear part on the rear side.

In the same way as in the previous example, the load receiving net 2 descends in the middle of the vertical transport path while keeping it substantially horizontal. However, near the lower end of the vertical transport path, the cables 1c and 1d on the rear side are once detoured upward. After that, it is detoured to the front side,
The rise of the ropes 1c and 1d on the rear side and the ropes 1a and 1 on the front side
In conjunction with the lowering of b, the receiving net 2 is inclined and extended, and the trash bag 5 is easily discharged.

[0010]

With respect to high-rise buildings such as condominiums, due to disaster prevention requirements, the garbage transport path space must be cut off from the living space by fire walls and fire doors (according to the Building Standards Law). Regulated). For this reason,
It is difficult to adopt a vertical transport device having a horizontal extension. This is because if the L-shaped garbage transfer path space including the horizontal extension is surrounded by a fire wall, the building structure becomes complicated. In addition, since this form requires a large installation space for the horizontally extending portion, it is difficult to adopt this form in an apartment or the like.

On the other hand, in a vertical transport device for directly discharging garbage bags from a vertical transport path, a fire wall and a fire door can be easily provided, and the installation space can be reduced. However, the following phenomena occurred in a prototype experiment of this vertical transport device.

FIG. 10 is an enlarged view of the vicinity of the lower end of the vertical transport device of FIG. Points A1, A2, A3, A4
Indicates the position at which the front horizontal bar 3a passes with the circulation of the rope, and points B1, B2, B3, and B4 indicate the passing positions of the corresponding rear horizontal bar 3b.

In the basic operation, first, each horizontal bar 3a,
3b is located at points A1 and B1 when the receiving net 2
Is largely bent at the center, and the garbage bag 5 is located at the position C1. Each horizontal bar 3a, 3b is moved from point A1, B1 to point A2.
While reaching B2, the receiving net 2 starts to tilt and extend. The deflection of the receiving net 2 moves to the front side, and the trash bag 5 moves to the position C2. Each horizontal bar 3a, 3b is point A
When passing through 3, B3, the receiving net 2 is extended most and loses its bending. Moreover, the receiving net 2 is greatly inclined. Therefore, the trash bag 5 slides down the receiving net 2. Thereafter, the horizontal bars 3a and 3b are points A4 and B4, respectively.
, And the receiving net 2 moves rearward and rearward.

However, in actual operation, each horizontal bar 3
When a and 3b pass through points A2 and B2, respectively, the front horizontal bar 3a interferes with the front side of the trash bag 5 that is about to move to the front side. Since the receiving net 2 is still bent, the garbage bag 5 and the receiving net 2 wrapping the garbage bag 5 partially protrude forward from under the front horizontal bar 3a. If the front horizontal bar 3a descends as it is, pinching will occur.

[0015] Due to such a phenomenon, the garbage bag cannot be discharged smoothly.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a vertical conveyance device which reduces the space of the conveyance path and smoothly discharges the load.

[0017]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, endless ropes circulating in the vertical direction are arranged at substantially four corners of a vertical transport path, and a predetermined length of each of the descending ropes is determined. At each height position, a horizontal bar that supports the corners of the load receiving net that has been deployed almost horizontally and that regulates the space between the cables on the front side and between the cables on the back side of the vertical transport path is inserted. At the same time, at the lower end of the vertical transport path, the front side rope is guided to the rear of the back side of the vertical transport path, and after the lower side of the vertical transport path, the rear side rope is guided to the front side, After passing through the lower end on the front side, it is guided to the rear of the back side of the vertical transport path, and at the rear side on the rear side, an empty load receiving net is configured to rise substantially upright, and the lower end of the vertical transport path In the vicinity, the load receiving net is temporarily received by a horizontal member.

[0018] The cable on the back side may be detoured in the front direction above a horizontal member for temporarily receiving the load receiving net.

The cable on the back side may be guided slightly upward while being detoured toward the front side.

[0020]

After guiding to the rear of the back side of the road, guiding the ropes 1c, 1d on the back side to the front side above the lower end of the vertical conveyance path, and passing through the lower end on the front side, then the rear side of the vertical conveyance path To the back of
In the rear part on the rear side, an empty load receiving net (not shown) is configured to be substantially raised and raised, and further, the load receiving net 2 is positioned near a lower end of the vertical transport path by a horizontal member (hereinafter referred to as a receiving stand). ) 6 so as to be temporarily received.

At the upper end of the vertical transport path, the front ropes 1a, 1b rising from the rear rear part are guided to the front side, and the rear ropes 1c, 1d are immediately guided downward. Thus, the slat is configured to be deployed substantially horizontally again. Each cable 1a, 1b, 1c,
The length of the net 1d is the same, and the load receiving net 2 is expanded substantially horizontally or substantially erected due to the difference in the path between the front ropes 1a, 1b and the rear ropes 1c, 1d at the upper and lower ends. Or can be.

The vertical transport device according to the present invention is configured to guide the cables 1c and 1d on the rear side slightly upward while detouring toward the front side above the cradle 6.

4a to 4f are guide members for guiding the cable in a desired direction. Specifically, the guide member 4a arranged at the front-side upper end guides the front-side ropes 1a and 1b from the guide member 4f downward. The guide member 4b arranged near the lower end on the front side guides the ropes 1c and 1d on the rear side from the guide member 4e downward. The guide member 4c arranged at the lower end on the front side includes the guide member 4a and the guide member 4
Each of the ropes 1a, 1b, 1c, 1d from b is guided rearward on the rear side of the vertical transport path. The guide member 4d arranged at the lower end on the back side is connected to each of the cords 1a, 1b, 1 from the guide member 4c.
Guide c and 1d upward. The guide member 4e arranged near the lower end on the rear side guides the ropes 1c and 1d on the rear side from the guide member 4f in a substantially front side direction. However, depending on the arrangement relationship between the guide members 4e and the guide members 4b, the ropes 1c and 1d on the rear side are guided obliquely slightly upward. Guide member 4f arranged at the upper end on the back side
Guides the front side ropes 1a and 1b from the guide member 4d to the front side, and simultaneously guides the rear side ropes 1 from the guide member 4d.
Guide c and 1d immediately downward.

The cable is preferably composed of a chain, and the guide member is preferably composed of a sprocket wheel. Alternatively, a rope and a pulley may be used. One or more of the guide members are connected to a power system (not shown), and drive each cable at a constant speed.

The cradle 6 is made of a plated steel plate or stainless steel. The receiving net 2 is made of a polyester material.

The receiving net 2 is directly connected to the cords 1a, 1a.
Instead of being attached to b, 1c, 1d, each corner of the receiving net 2 is attached to the front horizontal bar 3a and the rear horizontal bar 3b, and these horizontal bars 3a, 3b are connected to the ropes 1a, 1b, 1c, 1d, the receiving net 2 is indirectly connected to the ropes 1a, 1b, 1
c, 1d. The receiving net 2 is washed,
It is preferable to be detachable from the horizontal bars 3a and 3b for repair or the like.

The operation of discharging the garbage bags in the vertical transport device of FIG. 1 will be described. FIG. 2 is an enlarged view of the vicinity of the lower end of the vertical transport device of FIG.

As shown, the guide members 4e and 4b are provided at positions higher than the receiving table 6, respectively. Then, the ropes 1c and 1d on the rear side are wound around the lower side of the guide member 4e, and are wound around the upper side of the guide member 4b. The height of the guide members 4e and 4b is determined in consideration of the size of the deflection of the load receiving net 2, the size of the garbage bag 5, and the like.
e, a cable 1 on the back side from the lower side to the upper side of the guide member 4b
The passages c and 1d are set so as to incline slightly upward from the back side to the front side at a predetermined height on the cradle 6.

First, the horizontal bars 3a and 3b are points A1 and B1.
, The cargo receiving net 2 is largely bent at the center. When each of the horizontal bars 3a and 3b approaches the points A1 and B1, the central portion of the receiving net 2 comes into contact with the cradle 6.
When the horizontal bars 3a and 3b reach the points A1 and B1, the garbage bag 5 is supported by the cradle 6 at the position C1. The receiving net 2 loses the tension due to the weight of the trash bag 5.

While each of the horizontal bars 3a, 3b moves from the point A1, B1 to the point A3, B3, the front part of the receiving net 2 moves downward, and the rear part of the receiving net 2 moves in the front direction. Moving. After the front horizontal bar 3a has passed the vicinity of the point A2, the load receiving net 2 is pulled downward. Therefore, the portion of the load receiving net 2 on which the garbage bag 5 is placed slides on the receiving stand 6 in the front direction. Moving.

On the other hand, the horizontal bar 3b on the rear side moves from the point B1 to the point B
3, the rear horizontal bar 3b is in contact with the rear portion of the garbage bag 5, as indicated by the point B2. 5 will be pushed out to the front side. Therefore, the garbage bag 5
Moves from C2 to C3 and is discharged forward. During this time, the front horizontal bar 3a is present in front of the trash bag 5 from the point A1 to the position of the receiving tray 6, but since the trash bag 5 is supported by the receiving tray 6 at the position C1,
Even if the front horizontal bar 3a interferes with the trash bag 5, the load receiving net 2 wrapping the trash bag 5 partially protrudes forward from under the front horizontal bar 3a as in the conventional example. There is no. When the front horizontal bar 3a is lowered from the position of the cradle 6, there is no obstacle that interferes with the trash bag 5, so that the trash bag 5 is smoothly discharged.

Further, since the rear horizontal bar 3b moves diagonally upward from point B1 to point B3,
Will be slightly lifted. Therefore, the friction of the load receiving net 2 pressed against the garbage bag 5 against the cradle 6 is reduced, the movement of the center of gravity (rolling) of the garbage bag 5 is promoted, and the garbage bag 5 is more smoothly discharged. Become.

FIGS. 3 to 6 show an experimental prototype of the present invention.
Are shown in accordance with the respective timings. FIG.
It corresponds to points A1 and B1. At this time, the central portion of the receiving net 2 is landed on the receiving table 6. Front horizontal bar 3a
Is located slightly lower than the top of the garbage bag 5. FIG. 4 corresponds to an intermediate point between points A1 and B1 and points A2 and B2. At this time, the front side portion of the load receiving net 2 is removed from the front of the garbage bag 5, and the front horizontal bar 3 a is at substantially the same height as the cradle 6. FIG. 5 corresponds to points A2 and B2. At this time, the garbage bag 5 is pushed by the hidden rear horizontal bar 3b and protrudes from the receiving table 6. FIG. 6 corresponds to points A3 and B3. At this time, the trash bag 5 has already rolled off the cradle 6.

To summarize the above-described discharging operation, since the garbage bag 5 is supported by the receiving table 6, the load receiving net 2 does not swell greatly downward, and the front horizontal bar 3a does not pinch.

Since the rear horizontal bar 3b is moved substantially horizontally at an appropriate height on the receiving table 6, an action of pushing out the garbage bag 5 is obtained. Had only the function of mounting).

Since the rear horizontal bar 3b is obliquely moved slightly upward, the trash bag 5 is easily moved.

A remarkable effect is obtained.

Next, an application example in which the vertical transport device of the present invention is installed in a high-rise building will be described.

As shown in FIG. 7, a space for the vertical transport device is secured through each floor of the high-rise building 71. Guide members 4a and 4f are provided at the uppermost portion of this space, and guide members 4b to 4e and a cradle 6 are provided at the lowermost portion. The endless cable 1 is provided by these guide members 4a to 4f.
a, 1b, 1c, 1d are configured to be circulated in the vertical direction. Receiving net 2 is the entrance 7 of each floor
They are deployed almost horizontally every two. In addition, a garbage box 73 is installed near the inlet 72 of each floor. The lowermost floor is provided with an outlet 74,
The trash bag 5 is discharged from the cradle 6 through the discharge port 74.

The resident of the high-rise building 71 puts garbage into the garbage box 73. The garbage box 73 is provided with a garbage bag, and a staff member periodically closes the garbage bag 5 filled with garbage and throws it into the load receiving net 2 through the slot 72. When the loading of the garbage bags on each floor is completed, a staff member operates an operation button (not shown) provided on the lowermost floor to activate the vertical transport device. Cords 1a, 1b, 1c, 1d
Each time is lowered by one floor, the cargo receiving net 2 is landed on the cradle 6 and the trash bag 5 is discharged. The garbage bags 5 are discharged to a collecting drum 75 or a collection vehicle (not shown) via a horizontal conveyor (not shown) or directly from a discharge port 74.

As shown in the figure, since the space for the vertical transport device has a simple shape without any protruding portions, the fire wall and the fire door 7 can be easily formed.
6 and the space occupied by the high-rise building 71 is small. Then, the vertical transport device of the present invention installed in this space can discharge the garbage bag 5 extremely smoothly as described above.

[0043]

The present invention exhibits the following excellent effects.

(1) Since the load receiving net is temporarily received and supported by a horizontal member, the trash bag is discharged without the swelling of the load receiving net caused by the trash bag. do not do.

(2) Since the cable on the rear side is detoured to the front side above the horizontal member, the horizontal bar on the rear side pushes out the trash bag.
