  Patent Document 1 describes a vertical conveyance device for garbage configured to lower garbage discharged from each floor of a high-rise building within a chute. In the vertical conveying apparatus described in this patent document, waste to be discarded is placed in a chute in a state of being accommodated in a plastic bag having a predetermined size.

JP-A-3-72158

  By the way, as described in the above-mentioned patent document, the waste to be discarded is not stored in a plastic bag, but is stored in a reusable waste container from the viewpoint of reducing running costs and protecting the environment. In the state, it is considered to descend in the chute.

  However, in such a configuration, there is a possibility that the dust container lowered in the chute may be damaged by an impact when it reaches the lower end of the chute, or a loud sound may be generated. With regard to this point, in the vertical conveyance device described in the above-mentioned patent document, a plurality of openable and closable dust receiving shelves are provided inside the chute, and the inside of the chute is divided into a plurality of storage chambers by these dust receiving shelves. I am trying to partition it. That is, the garbage container put into the chute is sequentially transferred to the lower storage chamber by sequentially opening and closing a plurality of garbage receiving shelves, without giving a large impact to the garbage container, It becomes possible to descend in the chute.

  However, in this configuration, it is necessary to sequentially open and close a plurality of dust receiving shelves in the chute, which complicates the configuration of the vertical conveyance device.

  The technology disclosed herein has been made in view of such a point, and the object thereof is to provide a garbage container in a vertical conveyance device configured to lower the garbage container in a chute. An object of the present invention is to easily realize a configuration for reducing the impact when the lower end of the chute is reached.

  The technology disclosed herein includes a chute installed so as to pass through each floor of a high-rise building, and is configured to lower a garbage container discharged from any one of the floors in the chute. The present invention relates to a vertical conveyance device for garbage.

  The chute is arranged in a non-fixed state with respect to the first chute so as to be continuous with a first chute installed so as to penetrate each floor and a lower end of the first chute. A lower gate device that is attached and fixed to a lower end portion of the second chute and is configured to open and close a lower end opening of the second chute. Prepare.

  The lower gate device includes an opening / closing door that opens and closes a lower end opening of the second chute, and the opening / closing door closes the lower end opening of the second chute, The dust container that has descended in the chute is received, and the lower end opening of the second chute is opened, so that the received garbage container is discharged below the chute.

The vertical transfer device is configured such that the lower gate device is attached and fixed while urging the second chute upward so that the second chute is abutted against the first chute. A shock absorber supporting member that supports the chute and absorbs an impact when the dust container that has descended in the first and second chutes is received by the opening and closing door is further provided.

  According to this configuration, the chute installed so as to penetrate each floor of the high-rise building is configured to be divided into a first chute and a second chute at the lower end portion thereof. The second chute is disposed in a non-fixed state with respect to the first chute, and specifically, the second chute is abutted against the first chute by the buffer support member. , Supported while being biased upward. Thereby, in a normal state, the first chute and the second chute are in close contact with each other to form a continuous chute, and odor leakage from within the chute is avoided.

  A lower gate device is attached and fixed to a lower end portion of the second chute, and an opening / closing door of the lower gate device opens and closes a lower end opening of the second chute. When waiting for the garbage container to be put into the chute, the open / close door can receive the garbage container that has descended in the first and second chutes by closing the lower end opening of the second chute. In addition to preventing the leakage of odors from the chute.

  Then, when a garbage container containing garbage is introduced from any floor and the garbage container descends in the first and second chutes, the lower end opening of the second chute is closed. The open / close door receives the garbage container. At this time, the lower gate device having the opening and closing door is attached and fixed to the second chute, and the second chute is supported by the buffer support member, so that the impact force is generated by the buffer support member. Will be absorbed. Thus, the impact on the dust container is absorbed, the damage to the dust container is avoided, and the generation of sound is suppressed.

  Here, when the garbage container is received by the open / close door, the second chute that is not fixed to the first chute may temporarily move away from the first chute, but for a very short time. That is, there is no problem because the timing of the separation is after the dust container passes through the abutting position between the first chute and the second chute.

  In addition, it is conceivable that an impact absorbing structure is provided at the position of the opening / closing door that receives the garbage container instead of the configuration including the buffer support member. Must be further added, and the structure near the opening / closing door becomes complicated. On the other hand, the configuration in which the second chute, to which the lower gate device is attached and fixed, is supported by the buffer support member, when the garbage container is received with a simple configuration without complicating the structure near the opening / closing door. There is an advantage that it is possible to absorb the shock.

  The vertical transfer device may include a mechanism that adjusts the speed of the dust container that descends in the chute, for example, by controlling the pressure state in the chute. In this way, in addition to absorbing the shock by the buffer support member, by adjusting the lowering speed, the impact itself when the garbage container is received by the open / close door can be made as small as possible. It is advantageous to prevent the waste container from being damaged, and to suppress sound.

  The waste container discharged downward from the chute is placed on a loading platform of the transport vehicle, and the lower gate device passes the waste container that has passed through the lower end opening of the second chute to the transport vehicle. A guide unit that guides the door to be placed on a loading platform, the guide unit being reduced when the door is closed and extending downward when the door is open; It may be configured to switch between a contracted state and an expanded state in conjunction with the opening and closing of.

  In a configuration in which the waste container discharged from the chute is placed on the loading platform of the transport vehicle and transported to, for example, a waste processing chamber where garbage is collected, the waste storage body is securely placed on the loading platform of the transport vehicle. It is desirable to do.

  When the door is closed, in other words, when waiting for the trash container to be inserted, or when receiving the trash container, the guide part of the lower gate device is in a contracted state so that the lower part of the chute It is possible to avoid the interference with the transport vehicle traveling on the vehicle and to allow the transport vehicle to travel freely. This is advantageous in that the operation of the dust transport system including the vertical transport device and the transport vehicle is made smooth and the operation efficiency is improved.

  On the other hand, when the open / close door is opened, for example, when the received garbage container is discharged downward and placed on the carrier bed of the transport vehicle, the guide portion extends downward to remove the garbage container body of the transport vehicle. It is possible to place it securely.

The guide portion has a telescopic structure including a cylindrical inner member having an inner dimension surrounding the outer periphery of the dust container, and a cylindrical outer member configured to surround the inner member. The inner member has a flange portion extending outward at an upper end opening edge thereof, and the outer member has a flange portion extending inward at a lower end opening edge thereof; The guide portion may include a seal member that seals between the flange portion of the inner member and the flange portion of the outer member that overlap each other in the extended state.

  As described above, the guide portion extends in conjunction with the opening of the opening / closing door, but when the guide portion having a telescopic structure is extended, the gap between the flange portion of the inner member and the flange portion of the outer member is By sealing the sealing member, when the opening / closing door is opened and the lower end opening of the second chute is opened, the sealing performance is maintained in the guide portion continuous with the second chute. This is advantageous for suppressing odor leakage.

  Further, as will be described later, when the vertical conveying device is configured to suck up the garbage container by sucking the inside of the chute, keeping the sealing property in the extended guide member prevents the negative pressure leakage. This makes it possible to reliably suck up the garbage container.

  The open / close door is opposed to the horizontal direction so as to close the lower end opening of the second chute, and can be placed on the dust container that has been lowered on the upward placement surface, respectively, in a reverse direction. Each door member has a pair of door members configured to open the lower end opening of the second chute by rotating downward, and each door member opens the opening and closing door, and In the state where the guide portion is extended, the placement surface is disposed in the outer member so as to connect the lower end opening of the second chute and the upper end opening of the inner member, whereby the dust It may be configured to guide the passage of the container in the vertical direction.

  By doing so, the open / close door combines the function of opening and closing the lower end opening of the second chute, the function of receiving the dust container, and the function of guiding the dust container when discharging downward. Thus, the received garbage container can be reliably placed on the loading platform of the transport vehicle with a simple configuration. Further, as will be described later, when the vertical conveying device is configured to suck up the garbage container by sucking the inside of the chute, the structure described above guides the garbage container sucked up from the loading platform of the conveying vehicle. It is possible to reliably pass the inside of the part and raise it into the chute.

  Each door member has a guide wall standing on each side edge in a direction orthogonal to the facing direction, and each guide wall is in a state where the opening / closing door is opened and the guide portion is extended. In the outer member, between the lower end opening of the second chute and the upper end opening of the inner member, it is configured to guide the passage of the dust container in the vertical direction, Also good.

  Thereby, when the door is opened, the placement surface of each door member regulates the movement in the opposite direction with respect to the dust container that passes through the outside member of the guide portion in the vertical direction. Each guide wall of the member regulates movement in a direction orthogonal to the facing direction with respect to the dust container that passes through the outer member in the vertical direction. Thus, the garbage container can reliably move in the vertical direction within the outer member, and can be reliably placed on the loading platform of the transport vehicle and can be reliably raised into the chute.

  The lower gate device includes a drive unit configured to open and close the open / close door configured in a double-spread type, and the drive unit is configured so that each of the pair of door members rotates in synchronization with each other. It has an endless body that connects the rotation shafts of the door members to each other, and the endless body is crossed in an 8-shape so that the rotation directions of the door members are opposite to each other and wound around the rotation shafts. It may be hung.

  With an endless body (for example, a chain) that crosses in a figure 8 shape and is wound around each rotation shaft, the pair of door members can be rotated in the opposite directions with a simple configuration. This is advantageous when the waste container received by the open / close door is discharged downward and the dust container is stably moved downward and placed on the loading platform of the transport vehicle.

  The rotation shaft of any one of the pair of door members is drivingly connected to a driving source, and the driving unit is connected to the driving source and the driving source connected to the driving source. A torque limiter interposed between the movable shaft and the torque limiter when the dust container that has descended in the first and second chutes is received by the door; It is good also as being comprised so that transmission of this torque may be interrupted | transmitted to the said drive source side.

  As described above, since the second chute is supported by the buffer support member, the shock when the garbage container is received by the open / close door is absorbed by the buffer support member, but for example, the weight exceeding the specified value When dust or the like is thrown into the chute, the shock support member may not absorb the shock completely. In such a case, since a torque limiter is interposed between the drive source that is drivingly connected to each other and the rotation shaft of the door member, it is possible to cut off the transmission of a predetermined or higher torque to the drive source side. The drive source can be reliably protected.

  The chute is configured to suck up an empty garbage container by being sucked from the upper end portion thereof, and can be collected on each floor, and the guide portion has a lower end edge of the inner member in an extended state. It is good also as being comprised so that it may be the same as the upper end edge of the said refuse container mounted in the loading platform of the said conveyance vehicle, or it may be located below it.

  In the configuration in which the empty waste container is sucked up by suction from the upper end of the chute, when the guide portion is extended, the lower edge of the inner member is placed on the loading platform of the transport vehicle. It is desirable to be located at the same level as or lower than the upper edge. By doing so, it becomes possible to apply a suction force to the garbage container when suction is performed, and the dust container placed on the loading platform of the transport vehicle is surely sucked up and smoothly into the chute. It becomes possible to raise.

  A sensor that detects the dust container is attached to the second chute, and the opening and closing door may be configured to open and close based on detection of the sensor.

  In other words, this sensor can detect that the garbage container that has descended in the first and second chutes has been received by the opening and closing door, so that the opening and closing door can be opened based on the detection of this sensor. The received garbage container can be discharged downward. Further, since the sensor can detect that the dust container that has been sucked up and has passed through the lower end opening of the second chute, the door can be closed based on the detection of the sensor.

  The buffer support member may include a compression spring that generates an urging force for the second chute and an adjustment mechanism that adjusts the urging force of the compression spring.

  By doing so, the shock absorbing support member absorbs the impact when the garbage container is received by the opening / closing door by the compression spring compressing, so that it can sufficiently exhibit the absorbing ability even for a large impact force. It becomes possible. In addition, by adjusting the urging force of the compression spring, it is possible to adjust the shock absorption capacity, and it is possible to optimize the shock absorption capacity according to the installation environment and usage environment of the vertical transfer device Become.

  As described above, according to the above-described vertical dust transporting device, the lower gate device having the open / close door is attached and fixed after the lower end portion of the chute is separated into the first chute and the second chute. The second chute is supported by the buffer support member, so that the first chute and the second chute can be used when waiting for the introduction of the dust container or when the dust container is descending in the chute. The chutes can be made continuous with each other to prevent odor leakage, while when the garbage container is received by the open / close door, the shock can be absorbed by the buffer support member. Breakage and the like can be reliably avoided with a simple configuration.

  Hereinafter, a vertical dust transport device will be described with reference to the drawings. The description of the following embodiment is an example. FIG. 1 shows an overall view of the dust transport system 1. The garbage transport system 1 is a system for transporting garbage discharged from each floor to a garbage processing chamber 4 provided on the basement in a high-rise building (not shown). The dust transport system 1 is configured by combining a vertical transport device 2 and a horizontal transport device 3 to which the vertical transport device 2 is connected. The high-rise building can be exemplified by a building in which a person such as an apartment lives, a building such as a so-called office building, and the like, and there is no restriction on the type and usage. In the following description, the garbage transport system 1 installed in an apartment will be described as an example.

  The vertical conveyance device 2 is a device that efficiently conveys waste discharged from each floor of a high-rise building from each floor to the basement. Only one vertical transfer device 2 may be provided for a high-rise building, or a plurality of vertical transfer devices 2 may be provided at various locations of the high-rise building. For example, in a condominium, when a plurality of living spaces are provided on each floor, the vertical conveying device 2 may be installed for each living space so that one living space occupies one vertical conveying device 2. And you may install the several vertical conveying apparatus 2 so that the one vertical conveying apparatus 2 may be shared by several living spaces. In the example of FIG. 1, the first and second vertical transfer devices 2 are installed, but only a part of the second vertical transfer device 2 is illustrated. The vertical conveying device 2 is installed extending in the vertical direction so as to follow the high-rise building.

  On the other hand, the horizontal conveyance device 3 is a device that conveys the garbage conveyed to the basement by each vertical conveyance device 2 to the garbage processing chamber 4. The horizontal transfer device 3 is installed horizontally and spread on the basement of a high-rise building (here, an underground parking lot is used as an example, but the location where the horizontal transfer device is arranged is not limited to the underground parking lot). In this example, waste discharged from each floor is stored in a dust container 5 (see also FIG. 2 and the like) that is a reusable box-shaped container. Transports the garbage container 5 containing the garbage or the empty garbage container 5.

  The vertical transfer device 2 is arranged in parallel with the chute 21 for lowering the garbage container 5 discharged from each floor to the basement, the charging device 22 for loading the garbage container with respect to the chute 21, and the chute 21. A duct 23 that is disposed and lifts the empty garbage container 5 from the basement to each floor, and a collection device 24 that collects the empty garbage container 5 conveyed by the duct 23, and the like. Has been. The chute 21 and the charging device 22 constitute a lowering mechanism for lowering the garbage container 5, and the duct 23 and the collection device 24 are empty garbage containers 5 after the garbage is thrown away in the garbage processing chamber 4 as described later. Constitutes a raising mechanism for raising

  The chute 21 is configured in a cylindrical shape, and is arranged to extend linearly in the vertical direction through each floor shown in FIG. The inner method of the chute 21 is slightly larger than the outer method of the dust container 5. Although detailed illustration is omitted, the upper end portion of the chute 21 protrudes into the upper machine room of the high-rise building, and the lower end portion of the chute 21 reaches the basement.

  An upper end portion of the chute 21 is opened, and an intake portion 25 that opens and closes the upper end opening is attached to the upper end portion of the chute 21. The intake part 25 is configured by, for example, an opening adjustment damper capable of opening and closing the upper end opening of the chute 21 and adjusting the opening thereof. The damper opening degree of the intake section 25 is controlled by a sub-controller 62 described later, and the damper of the intake section 25 is closed in a normal state, in other words, in a non-energized state.

  The lower end portion of the chute 21 is also opened like the upper end portion, and a lower gate device 80 is provided at the lower end portion. The lower gate device 80 has an open / close door 81 that can open and close the lower end opening of the chute 21 (see FIG. 8 and the like), and the chute 21 is closed when the open / close door 81 is closed. While being able to receive the garbage container 5 that has descended in the area 21, the opened / closed door 81 is opened so that the received garbage container 5 can be loaded onto an automatic guided vehicle (for example, RailGuided Vehicle: RGV) 7 described later. it can. Moreover, the lower end part of the chute | shoot 21 is provided with the exhaust port 211 opened to a side so that opening and closing is possible. As will be described later, the exhaust port 211 maintains at least atmospheric pressure below the dust container 5 while the dust container 5 is descending in the chute 21, It functions to prevent odor leakage.

  Although not shown in the drawings, a side surface of the chute 21 is provided with a loading port for loading the garbage container 5 into the chute for each floor. The input device 22 is installed on each floor adjacent to the input port. Although not shown in detail, the input device 22 has a function of inputting the garbage container 5 carried by the user into the chute 21 through the input port. Have. The input device 22 is also provided with an operation panel that is operated by a user who throws away trash. This operation panel is used by the user for types of garbage (for example, combustible garbage including raw garbage, non-combustible garbage, bins and cans, etc.). At least a dust type selection switch and an input switch. The user inputs the type of garbage in the garbage container 5 set in the loading device 22 by operating the selection switch, and then turns on the loading switch. Thus, the charging device 22 temporarily opens the charging port formed in the chute 21, loads the garbage container 5 set by the user into the chute 21, and closes the charging port after the charging. I do. The input device 22 also performs sub-control on the information on the type of the input garbage and the identification information of the input device 22 that has input the dust container 5 (that is, information on the floor and chute on which the dust container 5 has been input). Output to the device 62.

  The chute 21 is provided with passage sensors 28 at equal intervals in the vertical direction, specifically on each floor. Each passage sensor 28 detects that the dust container 5 descending in the chute 21 has passed. Each passing sensor 28 is electrically connected to the sub-controller 62 as indicated by a broken line in FIG. 1, and outputs a detection signal to the sub-controller 62. The sub-controller 62 receives signals output from the input device 22 and the passage sensors 28, controls the driving of the intake portion 25, the lower gate device 80, and the like, and lowers the dust container 5 to the basement.

  Specifically, the lowering mechanism of the vertical transfer device 2 keeps the opening adjustment damper of the intake portion 25 closed when the garbage container 5 is put into the chute 21. By doing so, when the dust container 5 is lowered, the space above the dust container 5 in the chute 21 is restricted from inflow of air and becomes negative pressure. On the other hand, the exhaust port 211 at the lower end of the chute 21 is left open. Thereby, even if the refuse container 5 descends, air flows out of the chute 21 without resistance in the lower space. Accordingly, the space below the chute 21 is maintained at atmospheric pressure. Thus, when the dust container 5 is lowered, the internal pressure of the chute 21 is maintained at or below the atmospheric pressure, so that odor leakage can be effectively suppressed.

  Further, the lowering speed of the dust container 5 is reduced by the suction force due to the negative pressure in the space above the dust container 5. Therefore, it is possible to adjust the descent speed according to the mass of the dust container 5 by adjusting the opening of the opening adjustment damper of the intake section 25 and adjusting the negative pressure. The sub-controller 62 calculates the descending speed of the dust container 5 based on the detection signal from each passage sensor 28, and adjusts the opening degree of the opening adjusting damper based on the descending speed level.

  Further, when it is detected by the detection signal from the passage sensor 28 that the dust container 5 has reached the reference position having a predetermined height from the lower end of the chute 21, the sub controller 62 adjusts the opening of the intake section 25. Fully close the damper. As a result, the lowering speed of the dust container 5 can be reduced, the impact when the open / close door 81 of the lower gate device 80 receives the dust container 5 is reduced, and noise is generated and the dust container 5 is damaged. Can be effectively avoided.

  After the garbage container 5 is received by the open / close door 81, the sub controller 62 opens the open / close door 81 to load the garbage container 5 into the RGV 7 as described later.

  On the other hand, the duct 23, like the chute 21, is configured in a cylindrical shape, and is arranged so as to pass through each floor and extend linearly in the vertical direction. The inner method of the duct 23 is slightly larger than the outer method of the dust container 5. The upper end portion of the duct 23 also protrudes into the upper machine room of the high-rise building, and the lower end portion of the duct 23 reaches the basement.

  The upper end portion of the duct 23 is also open, and an exhaust device 27 for forcibly discharging the air in the duct 23 to the outside is attached to the upper end portion, unlike the chute 21. The exhaust device 27 is constituted by a fan, for example, and the fan is driven and controlled by the sub-controller 62.

  Although not shown in detail in the lower end portion of the duct 23, a lower gate device 80 is provided for sucking up the empty dust container 5 loaded on the RGV 7 and drawing it into the duct 23. The lower gate device 80 attached to the lower end portion of the chute 21 and the lower gate device 80 attached to the lower end portion of the duct 23 have the same configuration. In addition, an air inlet 231 that opens to the side is provided at the lower end of the duct 23 so as to be openable and closable. As will be described later, the air inlet 231 functions to suck air from the bottom of the duct 23 when the exhaust device 27 is driven to forcibly exhaust the air in the duct from above.

  Although not shown, a recovery port for recovering the dust container 5 in the duct 23 is formed on the side surface of the duct 23 for each floor. The collection device 24 is installed on each floor adjacent to the collection port, and although detailed illustration is omitted, the empty garbage container 5 that has risen in the duct 23 is placed outside the duct 23 through the collection port. Has the function of withdrawing and collecting. Specifically, although not shown in the drawing, the recovery device 24 swings between a standby position that stands up along the inner peripheral surface of the duct 23 and a support position that falls over the duct 23. It has a support device provided.

  The passage sensor 29 is also installed in the duct 23, and the passage sensor of the duct 23 is installed on each floor. Each passage sensor 29 detects that the dust container 5 rising in the duct 23 has passed. Each passing sensor 29 is electrically connected to the sub-controller 62 as indicated by a broken line in FIG. 1, and outputs a detection signal to the sub-controller 62.

  The raising mechanism of the vertical conveying device 2 configured as described above operates as follows under the control of the sub-controller 62 to raise the empty dust container 5. That is, if the RGV 7 loaded with the empty garbage container 5 stops at a position below the duct 23, the exhaust device 27 is activated, and the inside of the duct 23 becomes negative pressure. Through 80, the empty dust container 5 is sucked into the duct 23, and the empty dust container 5 rises in the duct 23. Based on the detection signal of the passage sensor 29, the sub controller 62 passes the dust container 5 rising in the duct 23 through the floor from which the dust container 5 is discharged (hereinafter referred to as a discharge floor). Determine whether or not. While the dust container 5 is moving up in the duct 23, the support devices on the respective floors are positioned at the standby position, whereby the dust container 5 is lifted up in the duct 23 without any trouble.

  Then, when it is detected by the detection signal of the passage sensor 29 that the empty garbage container 5 has passed through the discharge floor, the sub controller 62 moves the support device from the standby position through the collection device 24 of the discharge floor. The exhaust device 27 is stopped after the displacement to the support position. As a result, no suction force is generated, so that the empty dust container 5 is lowered and supported by the support device displaced to the support position. The collection device 24 pulls out the empty garbage container 5 supported by the support device to the outside of the duct 23 through the collection port. In this way, collection of the empty garbage container 5 is completed.

  As described above, in the garbage transport system 1, the dust container 5 discharged through the input device 22 on each floor returns to an empty state through the collection device 24 on the floor.

  In the illustrated example, a chute 21 for lowering the garbage container 5 and a duct 23 for raising the empty garbage container 5 are provided separately, but the garbage container 5 is formed by one chute (or duct). May be lowered and the empty garbage container 5 may be raised. As described above, the lower gate device 80 attached to the lower end portion of the chute 21 and the lower gate device 80 attached to the lower end portion of the duct 23 have the same configuration, and receive and discharge the dust container 5. Both the function and the function of sucking up and retracting the dust container 5 are provided.

  The lateral transfer device 3 includes a travel path 31 provided on the ground of an underground parking lot so as to be a predetermined path, and an RGV 7 that travels along the travel path 31. The traveling path 31 is configured to connect between each vertical conveyance device 2 and the garbage processing chamber 4. Specifically, the traveling path 31 includes a chute 21 of each vertical conveyance device 2 and an outward path 311 that connects the dust processing chamber 4, and a return path 312 that connects the dust processing chamber 4 and the duct 23 of each vertical conveyance device 2. It is configured in a loop connected so as to be endless. In FIG. 1, the forward path 311 and the return path 312 are drawn with their positions shifted vertically so that the forward path 311 is located above the one-dot chain line and the backward path 312 is located below the one-dot chain line for the sake of illustration. However, the forward path 311 and the return path 312 are actually provided at the same height position. The RGV 7 travels in the clockwise direction in FIG. 1 (that is, in one direction) along the loop-shaped traveling path 31. The RGV 7 transports the waste containers 5 discharged from the respective chutes 21 to the garbage processing chamber 4 and loads the waste containers 5 that have been emptied by throwing away the garbage in the garbage processing chamber 4. In the loaded state, it is conveyed to the duct 23. In FIG. 1, for convenience of explanation, a large number of RGVs 7 are shown, but the number of RGVs 7 can be set to an appropriate number. Further, the travel path 31 is not limited to being configured in a loop shape.

  The garbage disposal room 4 is a room for temporarily storing garbage discharged from each floor of a high-rise building until the garbage truck comes to collect it in a state where it is sorted according to its type. It is set up in an underground parking lot. In the garbage processing chamber 4, in the illustrated example, first to third three storage containers 41, 42, 43 are installed side by side in the traveling direction of the RGV 7. Each storage container 41, 42, 43 is a container for storing garbage for each type. The garbage processing chamber 4 also has first to third reversing devices for putting the garbage in the garbage container 5 loaded in the RGV 7 into the first to third storage containers 41, 42, 43, respectively. 44, 45, 46 are installed corresponding to the respective storage containers 41, 42, 43. It should be noted that the number of storage containers and reversing devices installed in the garbage processing chamber 4 can be set to an appropriate number according to the number of types of garbage to be separated.

  As shown in FIG. 2, the RGV 7 is provided on the rear side of the vehicle body 72, a chassis 71 configured in four wheels, a vehicle body 72 that is disposed in the front portion of the chassis 71 and accommodates a controller or the like described later, and And a loading platform 73 on which the garbage container 5 is loaded. The RGV 7 automatically travels along the travel path 31 while being guided by the rails 32 provided along the travel path 31. In other words, the dust container 5 containing the dust is transported between each chute 21 and the dust processing chamber 4, and the empty dust container 5 is transported between the dust processing chamber 4 and each duct 23. .

  The dust transport system 1 is controlled by a main controller 61 and sub-controllers 62 (only one is shown in FIG. 1) provided corresponding to each vertical transport device 2. The main controller 61 controls the entire dust transport system 1, and the sub controller 62 mainly controls the vertical transport device 2. A PC 63 is connected to the main controller 61, and the main controller 61 provides the PC 63 with information related to the operating status of the dust transport system 1 (total amount of input of dust, input history, etc.). The administrator of the dust transport system 1 can check the operation status of the dust transport system 1 through the PC 63.

  2, 3, and 8 to 10 are diagrams illustrating a configuration of the lower gate device 80 provided at the lower end portion of the chute 21. Since the lower gate device 80 provided at the lower end portion of the duct 23 has the same configuration, the description thereof is omitted here. In the following description, for the sake of convenience, FIG. 3 is the front surface of the lower gate device 80, FIG. 2 is the back surface of the lower gate device 80, and the direction orthogonal to the paper surface in FIGS. Further, the right side in FIG. 3 is the right side, the left side is the left side, the upper side in the page is the upper side, and the lower side is the lower side.

  The chute 21 includes a first chute 21a disposed through each floor and a second chute 21b disposed so as to be continuous with the lower end of the first chute 21a. Has been. A flange portion 21c is provided at the lower end opening edge of the first chute 21a, and a flange portion 21d is similarly provided at the upper end opening edge of the second chute 21b. During normal times (that is, as described later, when waiting for the garbage container 5 to be put into the chute 21, including when the garbage container is descending in the chute 21), the first chute The continuous chute 21 is configured by the flange portion 21c of 21a and the flange portion 21d of the second chute 21b coming into close contact with each other. However, the 1st chute 21a and the 2nd chute 21b are not couple | bonded, and are only contact | abutting. The support structure for the second chute 21b will be described later.

  An opening / closing door 81 for opening and closing the opening is attached to the lower end opening of the second chute 21b as shown in FIGS. The open / close door 81 is configured as a double door opening type that opens downward by a pair of door members 811 and 811 facing in the left-right direction. Each door member 811 is attached to an outer member 852 (to be described later) of the lower gate device 80 so that a base end portion thereof rotates around rotation shafts 82L and 82R extending in the front-rear direction.

  As shown in FIG. 4, each door member 811 is a substantially plate-like member, and has a mounting surface 812 that receives the dust container 5 and faces upward when the lower end opening of the second chute 21 b is closed. Have. The door member 811 is provided with guide walls 813 and 813 extending in the left-right direction on both side edges in the front-rear direction orthogonal to the left-right direction. As will be described later, the mounting surface 812 and each guide wall 813 raise the dust container 5 when the dust container 5 is lowered (in the lower gate device 80 attached to the lower end portion of the duct 23). At the time).

  A seal portion 814 that contacts each other when the door 81 is closed is provided at the front end of each door member 811, and at a predetermined position on the upper surface of each door member 811. A seal portion 815 is provided with which the lower end opening edge of the second chute 21b contacts when the open / close door 81 is closed (see also FIG. 8). By these seal portions 814 and 815, when the open / close door 81 closes the lower end opening of the second chute 21b, the sealing performance of the chute 21 is secured, and odor leakage or the like is avoided.

  The opening / closing door 81 is driven to open and close by the drive unit 83. The drive unit 83 includes an electric motor 831 as a drive source, a sprocket 832 fixed to a front end portion of the rotation shaft 82L disposed on the left side of the pair of rotation shafts 82L and 82R, and an electric motor. A power transmission chain 833 (shown in phantom in FIG. 3) for drivingly connecting the motor 831 and the left rotation shaft 82L via the sprocket 832 and the back side of each of the pair of rotation shafts 82L and 82R , A pair of rotating shafts 82L and 82R are configured to include a synchronizing chain (an example of an endless body) 834 (see FIG. 2) for rotating in opposite directions and in synchronization with each other.

  As shown in FIGS. 6 (a) and 6 (b), the synchronization chain 834 is crossed into a figure of 8 on the same plane (here, the plane including the left and right directions and the up and down direction), and a pair of rotations. The shafts 82L and 82R are wound around the sprockets 835L and 835R attached to the rear end portions of the shafts 82L and 82R, respectively. The synchronous chain 834 includes a first chain portion 8341 wound around the right sprocket 835R, a second chain portion 8342 wound around the left sprocket 835L, one end of the first chain portion 8341, and a second chain. A first cross portion 8343 that connects one end of the portion 8342 to each other, and a second cross portion 8344 that connects the other end of the first chain portion 8341 and the other end of the second chain portion 8342 to each other. It is configured.

  Of these, the first cross portion 8343 includes two bars 8345 and 8345 arranged in parallel at a predetermined interval in the front-rear direction, and both ends of the bars 8345 and 8345 are Each is connected to one end of the first chain portion 8341 and one end of the second chain portion 8342 via an attachment piece 8346. The length of each of the two bars 8345 and 8345 can be adjusted by changing the screwing amount of the bolts and nuts, so that the two rods 8345 and 8345 are wound between the two sprockets 835L and 835R. It is possible to adjust the tension of the synchronized chain 834 to be adjusted.

  The second cross portion 8344 has two rods that are coupled to the other end of the first chain portion 8341 and the other end of the second chain portion 8342, respectively, and constitute the first cross portion 8343, respectively. It is constituted by a bar material that passes between the members 8345 and 8345.

  The synchronous chain 834 having such a configuration is compared in a configuration in which the pair of rotating shafts 82L and 82R is relatively wide and it is difficult to connect the pair of rotating shafts 82L and 82R to each other by a gear train. The pair of rotating shafts 82L and 82R can be connected at a low cost. Note that the configuration of the synchronization chain 834 is not limited to the configuration described above. In particular, various configurations can be adopted as the configuration of the first and second cross portions 8343 and 8344. For example, although illustration is omitted, the first cross portion 8343 is not constituted by the two bar members 8345 and 8345 arranged in parallel, but is a long hole through which the bar member constituting the second cross portion 8344 can pass. It is also possible to constitute by an elongated plate-like member formed with.

  The sprocket 832 that is drivingly connected to the electric motor 831 is provided with a torque limiter, although not shown in detail. As will be described later, this torque limiter has a function of interrupting transmission of a torque exceeding a predetermined value to the electric motor 831 side when an impact is applied to the door 81. As such a torque limiter, for example, a commercially available friction plate type sliding torque limiter can be adopted.

  When the electric motor 831 is driven by the drive unit 83 configured as described above, the driving force is transmitted to the left rotation shaft 82L via the power transmission chain 833, and the door member 811 rotates around the rotation shaft 82L. At the same time, a reverse driving force is transmitted to the right rotation shaft 82R via the synchronous chain 834, and the door member 811 rotates in the reverse direction around the rotation shaft 82R. Thus, the open / close door 81 having the pair of door members 811 is configured in a downward facing double door type, with the lower end opening of the second chute 21b shown in FIG. 8 fully closed, and the second chute shown in FIG. It switches to the state which opened the lower end opening of 21b fully.

  As shown in FIG. 3, limit switches 84 that detect the fully closed state of the open / close door 81 and the fully open state of the open / close door 81 are provided at the front end of the right rotation shaft 82 </ b> R. . As will be described later, the sub controller 62 receives the detection result of the limit switch 84 and controls the operation of the lower gate device 80.

  The lower gate device 80 also has a guide portion 85. The guide portion 85 is a portion that guides the vertical movement of the dust container 5 between the second chute 21b and the loading platform 73 of the RGV 7. As shown in FIGS. 8 to 10, the guide portion 85 has a telescopic structure including an inner member 851 and an outer member 852, and is thereby configured to expand and contract in the vertical direction.

  That is, the outer member 852 is a hollow cylindrical member whose upper end and lower end are opened, and is fixed to the second chute 21b so as to be continuous with the lower end portion of the second chute 21b. ing. Thereby, the inside of the second chute 21b and the inside of the outer member 852 communicate with each other through the lower end opening of the second chute 21b. As is apparent from FIG. 10, the inner member 851 is a cylindrical member having an inner dimension surrounding the outer periphery of the dust container 5 and having both upper and lower ends opened, and is disposed inside the outer member 852. Has been. In other words, the outer member 852 is configured to surround the inner member 851. The inner member 851 is configured to be movable relative to the outer member 852 in the vertical direction. The inner member 851 is in a reduced state in which most of the inner member 851 is located inside the outer member 852 (see FIG. 8), and Most of 851 switches to the extended state (refer FIG. 2, 10) which protrudes below from the lower end opening of the outer side member 852. FIG. Here, in the extended state, the guide portion 85 is set so that the lower end portion of the inner member 851 is positioned below the upper end portion of the dust container 5 placed on the loading platform 73 of the RGV 7. Further, the lower end portion of the inner member 851 expands outward. In particular, this makes it easier to extrapolate the inner member 851 to the upper end of the dust container 5 when the guide part 85 is extended when the dust container 5 placed on the loading platform of the RGV 7 is sucked up. As is apparent from FIG. 2, when the guide portion 85 is in the extended state, it interferes with the vehicle body 72 of the RGV 7, but when the guide portion 85 is in the contracted state, it does not interfere with the RGV 7 and the RGV 7 It is possible to travel freely below the chute 21.

  As shown in FIG. 5, a flange 8511 that extends outward is provided at the upper end opening edge of the inner member 851, and the lower end opening edge of the outer member 852 faces inward as shown in FIG. A flange portion 8521 is provided. The flange portions 8511 and 8521 overlap each other when the guide portion 85 is in the extended state. The seal member 853 that seals between the flange portion 8511 and the flange portion 8521 is an outer member. It arrange | positions so that the perimeter of the lower end opening of 852 may be enclosed. As will be described later, when the guide portion 85 is in the extended state, the open / close door 81 is opened, and the lower end opening of the chute 21 is opened, but the space between the inner member 851 and the outer member 852 is sealed. The securing is advantageous for suppressing odor leakage, and in the lower gate device 80 attached to the lower end portion of the duct 23, the inner member 851 and the outer member 852 are used when the dust container 5 is sucked and sucked up. It is advantageous for efficiently sucking up the dust container 5 by preventing negative pressure leakage between the two.

  As shown in FIG. 5, rollers 8512 are attached to the inner member 851 at the four corners of the upper surface of the flange portion 8511. Each roller 8512 is configured to roll on the inner wall surface of the outer member 852. As a result, the inner member 851 can move in the vertical direction relative to the outer member 852 so that the guide portion 85 smoothly switches between the contracted state and the stretched state.

  As shown in FIGS. 2 and 3, the inner member 851 is configured to reciprocate vertically by a link mechanism 854. The link mechanism 854 is pivotally supported by a total of four levers 8541 attached to the front and back end portions of the left and right pivot shafts 82L and 82R of the door 81, and the levers 8541 and It consists of four link bars 8542 extending downward. On the front side and the back side of the inner member 851, the lower end of each link bar 8542 arranged with a space in the left-right direction is fixed to the lower end portion of the inner member 851. With such a configuration, as described above, the link mechanism 854 causes each lever 8541 to rotate in accordance with the pair of rotating shafts 82L and 82R rotating in the opposite directions in synchronization with each other, The inner member 851 is reciprocated in the vertical direction via the link bar 8542.

  Here, since the lever 8541 of the link mechanism 854 is fixed to the pivot shafts 82L and 82R of the opening / closing door 81, the opening / closing of the opening / closing door 81 and the expansion / contraction of the guide portion 85 are synchronized in the lower gate device 80. It will be. Specifically, as shown in FIG. 8, when the opening / closing door 81 is closed, the guide portion 85 is in a contracted state, and from this state, the rotation shafts 82 </ b> L and 82 </ b> R rotate and the opening / closing door 81 gradually moves. As it opens, the guide portion 85 also gradually expands (see FIG. 9), and as shown in FIG. 10, when the open / close door 81 is fully opened, the guide portion 85 is in the extended state. When the open / close door 81 is fully opened and the guide portion 85 is in the extended state, the placement surface 812 of each door member 811 is located inside the outer member 852 so that the lower end opening of the second chute 21b and the inner member 851 are placed. Are arranged facing each other in the left-right direction so as to be connected to the upper end opening. The guide wall 813 of each door member 811 is also arranged to connect the lower end opening of the second chute 21b and the upper end opening of the inner member 851. In this way, the dust container 5 that passes through the outer member 852 in the vertical direction is guided by the mounting surface 812 of each door member 811 and the guide wall 813.

  The flange portion 21 d of the second chute 21 b to which the lower gate device 80 is attached is supported by the buffer support member 9. A total of four buffer support members 9 are arranged on the front side and the back side, with a space in the left-right direction. Although not shown, the first chute 21a is fixed to the high-rise building by a separate fixing means.

  The buffer support member 9 is disposed between the frame 90 that is indirectly fixed to the ground and the flange portion 21d of the second chute 21b. As shown in detail in FIG. 7, the buffer support member 9 includes a base 91 fixed to the frame 90, a support shaft 92 provided integrally with the base 91 and extending vertically upward, and an upper end of the support shaft 92. And a base 93 fixed to the lower surface of the flange portion 21d of the second chute 21b, and a base 91 and a base 93, which are extrapolated to be movable along the support shaft 92. In the state where the compression coil spring 94 disposed so as to surround the support shaft 92, the stopper 95 fixed to the support shaft 92 on the upper side of the receiving base 93, and the lower end of the compression coil spring 94 are in contact with each other. And an adjustment nut 96 that is screwed into a threaded portion provided at the lower portion of the support shaft 92. As described above, in the buffer support member 9, the base 91 is fixed to the frame 90, and the receiving base 93 is fixed to the lower surface of the flange portion 21d of the second chute 21b. The second chute 21b is urged upward and supported by the elastic restoring force so as to abut against the first chute 21a, thereby supporting the second chute 21b. Thus, the second chute 21b normally continues in a state of being in close contact with the first chute 21a, and odor leakage from the chute 21 is prevented.

  Further, since the second chute 21b is supported by the compression coil spring 94 of the buffer support member 9, when the dust container 5 that has descended in the chute 21 is received by the mounting surface 812 of the open / close door 81, The entire lower gate device 80 and the second chute 21b move downward to absorb the impact. Since the compression of the compression coil spring 94 is used, a sufficient absorption capacity can be exhibited for a large impact force.

  When the buffer support member 9 absorbs an impact, the second chute 21b may be temporarily separated from the first chute 21a. However, even if the second chute 21b is separated from the first chute 21a, it is only a very small amount in a very short time, and the timing at which the first chute 21a and the second chute 21b are separated. Is after the dust container 5 has passed through the flange portions 21c and 21d of the first and second chutes 21a and 21b, so that the problem does not occur.

  By changing the position of the adjustment nut 96 of the buffer support member 9, it is possible to change the amount of compression of the compression coil spring 94 between the cradle 93 (that is, the stopper 95) and the adjustment nut 96. This makes it possible to change the degree of shock absorption by the buffer support member 9. For example, after the vertical conveyance device 2 is installed in a high-rise building, the degree of impact absorption by the buffer support member 9 may be adjusted according to the installation environment and the use environment.

  As shown in FIG. 3, a container detection sensor 100 for detecting the dust container 5 is attached to the second chute 21b. The container detection sensor 100 is configured by a light detection sensor that detects light transmitted through a window 21e provided in the second chute 21b (that is, light emitted from a light emitting unit (not shown)). The container detection sensor 100 detects the dust container 5 by detecting that the light is blocked when the dust container 5 passes through the chute 21. The container detection sensor 100 outputs a detection signal to the sub controller 62. The container detection sensor 100 detects that the garbage container 5 is received by the open / close door 81 when the garbage container descends in the chute 21. In the duct 23, the container detection sensor 100 detects that the dust container 5 has passed through the open / close door 81 when the dust container 5 is raised.

  Reference numeral 101 in FIG. 8 and the like denotes a regulating roller 101 configured to regulate the horizontal movement of the second chute 21b supported by the buffer support member 9 while allowing the vertical movement. It is. Reference numeral 102 denotes a support roller 102 configured to prevent the guide portion 85 drivingly connected to the electric motor 831 from being moved by a reaction force during driving.

  The operation control of the lower gate device 80 having such a configuration will be described with reference to the flowchart of FIG. The sub-controller 62 performs control related to this flow. This flow starts when the garbage container 5 is thrown into the chute 21 from any floor. At this time, the lower gate device 80 is in a state of waiting for the garbage container 5 to be put in. Specifically, as shown in FIG. 8, the open / close door 81 is in a closed state. The dust container 5 that has been thrown into the chute 21 and lowered through the chute 21 is received by the open / close door 81 in the closed state.

  As described above, since the lowering speed of the dust container 5 is controlled by adjusting the pressure inside the chute 21, it is avoided that a large impact is generated when the dust container 5 is received by the open / close door 81. The Even when the garbage container 5 is heavy and cannot be sufficiently decelerated, and when it is received by the door 81, the second chute 21b can be By being supported, the entire second chute 21b and the lower gate device 80 can be moved downward to absorb the impact. In this way, it is possible to reliably avoid the dust container 5 from being damaged. Further, the sound when the garbage container 5 is received by the open / close door 81 is also suppressed.

  Furthermore, when the garbage container 5 having a weight exceeding a specified value is thrown in, the shock support member 9 may not sufficiently absorb the impact. In such a case, the torque limiter attached to the sprocket 832 is operated to prevent the impact force from being transmitted to the electric motor 831 via the power transmission chain 833. Thus, the drive source is protected.

  The container detection sensor 100 detects that the open / close door 81 has received the garbage container 5. That is, the determination in step S111 in the flow of FIG. 11 is YES, and the flow moves to step S112.

  In step S112, it is determined whether or not the RGV 7 has arrived at a position below the chute 21. The sub controller 62 acquires information related to the operation of the RGV 7 from the main controller 61, for example. Step S112 is repeated until the RGV 7 arrives at the lower position of the chute 21 and its preparation is completed. After the preparation of RGV 7 is completed, the flow proceeds from step S112 to step S113.

  In step S113, driving of the electric motor 831 is started, and the opening / closing door 81 configured in a double-spread type is started to be opened. Accordingly, as shown in FIG. 9, the dust container 5 gradually descends through the space between the pair of door members 811. At the same time, the guide portion 85 gradually expands. Since the pair of door members 811 are rotated synchronously by the synchronization chain 834, the dust container 5 can be stably lowered.

  In subsequent step S114, it is determined whether or not the opening / closing door 81 is fully opened based on the detection result of the limit switch 84, and steps S113 and S114 are repeated until the opening / closing door 81 is fully opened. When the door 81 is fully opened, the process proceeds from step S114 to step S115, the electric motor 831 is stopped, and the door 81 is stopped.

  As shown in FIG. 10, when the opening / closing door 81 is fully opened and the guide portion 85 is in the extended state, the placement surface 812 of each door member 811 is connected to the lower end opening of the second chute 21 b and the inner member 851. The guide walls 813 of the door members 811 are also arranged so as to extend in the vertical direction. In this way, the lower end opening of the second chute 21b and the upper end opening of the inner member 851 are continuous, and the dust container 5 is lowered while being guided by the mounting surface 812 and the guide wall 813. do. As a result, the garbage container 5 is surely placed on the loading platform 73 of the RGV 7 (see also FIG. 2).

  If the trash container 5 is placed on the loading platform 73 of the RGV 7, the container detection sensor 100 will not detect the trash container 5, so the determination in step S116 is YES. The flow moves from step S116 to S117. On the other hand, if the determination in step S116 is NO (for example, when the container detection sensor 100 remains in a state where the garbage container 5 is detected after the open / close door 81 is fully opened), the open / close door is opened. Even though 81 is opened, there is a possibility of an abnormality such that the garbage container 5 is caught somewhere and does not descend, so the process proceeds to step S1111 to give a failure alarm.

  In step S117, the drive of the electric motor 831 is started and the opening / closing door 81 starts to be closed, and in the subsequent step S118, it is determined based on the detection result of the limit switch 84 whether the opening / closing door 81 is fully closed. Until the door 81 is fully closed, steps S117 and S118 are repeated. When the door 81 is fully closed, the process proceeds from step S118 to step S119, the electric motor 831 is stopped, and the door 81 is stopped. In step S1110, the process waits for the garbage container 5 to be put in and returns.

  FIG. 12 shows a control flow of the lower gate device 80 when attached to the lower end of the duct 23. This flow starts when the RGV 7 on which the empty garbage container 5 is placed on the loading platform 73 arrives at a position below the duct 23. At this time, the open / close door 81 is in a closed state, and the guide portion 85 is in a contracted state. Therefore, the RGV 7 can travel without interfering with the guide portion 85. In step S121 after the start of the flow, it is determined whether or not preparation for sucking the dust container 5 is completed. If the suction preparation is ready, the flow moves from step S121 to step S122.

  In step S122, the driving of the electric motor 831 is started and the opening / closing door 81 starts to be opened. In step S123, it is determined whether or not the opening / closing door 81 is fully opened. As described above, when the opening / closing door 81 is opened, the guide portion 85 starts to expand, and when the opening / closing door 81 is fully opened, the guide portion 85 is in an extended state, and the lower end portion of the inner member 851. However, it comes to be extrapolated by the upper end part of the refuse container 5 mounted in the loading platform 73 of RGV7 (refer FIG. 10).

  If it is detected that the open / close door 81 is fully open based on the detection result of the limit switch 84, the flow proceeds from step S123 to step S124, and the electric motor 831 is stopped. Thereafter, in step S125, the exhaust device 27 attached to the upper end portion of the duct 23 is activated. In this way, the dust container 5 is sucked up from the lower end opening of the inner member 851 by making the inside of the duct 23 have a negative pressure. As described above, the airtightness is maintained when the guide portion 85 is in the extended state, and the lower end portion of the inner member 851 is positioned below the upper end of the dust container 5. It is possible to prevent the negative pressure from leaking when the device 27 is activated, and to suck up the empty dust container 5 efficiently. Note that the lower end portion of the inner member 851 may be located at the same position as the upper end of the dust container 5 when the guide portion 85 is in the extended state.

  The sucked-up dust container 5 moves up in the outer member 852 of the guide portion 85 while being guided by the placement surface 812 and the guide wall 813 of each door member 811 and moves into the second chute 21b. . The garbage container 5 will rise smoothly in the guide portion 85. In step S126, it is determined whether or not the container detection sensor 100 has detected the passage of the dust container 5 by switching from on to off. When the passage of the garbage container 5 is detected, the flow proceeds from step S126 to S127. On the other hand, when the detection of the container detection sensor 100 does not switch from on to off (for example, the container detection sensor 100 does not turn on even after a predetermined time has elapsed since the start of the exhaust device 27, or the container detection sensor 100 If it does not turn off even after a predetermined time has elapsed after turning on, the process proceeds to step S1212 to issue a failure alarm.

  In step S127, it is determined whether or not the rising dust container 5 has passed through the air inlet 231 provided in the lower portion of the duct 23, and the process waits in this step until it passes. After the dust container 5 has passed, the process proceeds to step S128, where the electric motor 831 starts to be driven and the open / close door 81 starts to close. In step S129, it is determined whether the door 81 is fully closed. The door closing operation is continued until the door 81 is fully opened (steps S128, S129). If closed, the process proceeds to step S1210 and the electric motor 831 is stopped. Thus, by closing the opening / closing door 81 at an early stage, the guide portion 85 is in a contracted state, so that the RGV 7 can freely travel below the duct 23. This has the advantage that the operation of the dust transport system including the vertical transport device 2 and the horizontal transport device 3 is made smooth. Thereafter, the flow waits for the arrival of the next RGV 7 in step S1211.

  As described above, according to the vertical transfer device 2 having the above-described configuration, in the lower gate device 80, the opening / closing door 81 is attached to a mechanism for opening / closing the opening / closing door 81, a mechanism for extending / contracting the guide portion 85, and the like. In such a complicated place, a shock absorbing support member for absorbing the impact of the dust container 5 is not provided at the location of the second chute 21b. 9 is provided, there is an advantage that the configuration is simplified. In addition, since the shock absorbing member 9 can effectively absorb the impact when the dust container 5 is received by the open / close door 81, it is possible to reliably avoid damage to the dust container 5 and the like. Generation of sound can be suppressed.
