Description

  The present invention relates to a dust chute system installed in a building such as an apartment house.

For example, in Patent Document 1, as an example of a dust chute system, there are formed inlets that are arranged to extend in the vertical direction along a building and into which garbage is thrown into a plurality of predetermined positions in the middle of the vertical direction. A chute, a conveyor disposed at a position below the chute and receiving the dust falling in the chute and transporting it in the horizontal direction, and disposed on the discharge end side of the conveyor to accommodate the waste conveyed by the conveyor There is disclosed a system including an accommodating portion.
JP-A-9-202405

  By the way, the dust chute system disclosed in the patent document has a conveyor between the chute and the accommodating portion, and the dust falling in the chute is not directly accommodated in the accommodating portion. As a configuration example, there is a system in which a container with a wheel (collector) is disposed below the lower end opening of the chute without installing a conveyor. In this system, garbage falling in the chute is directly stored in the collector, and when the garbage in the collector reaches a predetermined amount, the transporter transports the collector to a predetermined collection site and discards the garbage. After that, the empty collector is again placed below the lower end opening of the chute.

  However, in a dust chute system that directly accommodates dust in the collector, the chute opening area is smaller than the collector opening area, so that dust accumulates in a mountain with the center of the collector at the top in the collector. Will end up. Thereby, the upper four corners in the collector become dead spaces, and the accommodation efficiency of the collector is lowered accordingly. As a result, there is an inconvenience that the number of times the collector is conveyed increases and the work efficiency is lowered.

  However, for example, it is not desirable in terms of safety and hygiene to flatten such mountainous garbage manually.

  The present invention has been made in view of such points, and an object of the present invention is to provide a dust chute system in which dust is automatically and uniformly contained in a collector, thereby improving safety and hygiene. The purpose is to improve the transport work efficiency without lowering the surface.

  According to one aspect of the present invention, the dust chute system is arranged to extend in the vertical direction along the building, and is formed with an input port through which garbage is input at at least one predetermined position in the middle of the vertical direction. And a collector that is disposed at a garbage receiving position that is a position below the lower end opening of the chute and that receives the garbage falling in the chute and is transported from the garbage receiving position in a state in which the garbage is accommodated. And comprising.

  The dust chute system further includes dust storage / discharge means attached to a lower end of the chute and temporarily storing garbage falling in the chute, and the dust storage / discharge means is a storage that communicates with a lower end opening of the chute. And a discharge gate that opens and closes an opening formed at the lower end of the storage portion, and opens the discharge gate when a predetermined amount of waste is stored in the storage portion, so that the waste in the storage portion is removed. Discharge into the collector.

  According to this configuration, since the dust storage and discharge means is attached to the lower end of the chute, the dust falling in the chute is temporarily stored in the storage portion thereof. Then, when a predetermined amount of garbage is stored in the storage unit, the discharge gate is opened, and the dust in the storage unit is discharged into the collector at a time. Therefore, unlike the case where the dust is directly stored in the collector from the chute having an opening area smaller than the opening area of the collector, the dust is deposited uniformly in the collector. Therefore, it is not necessary to flatten the garbage in the collector by hand, improving safety and hygiene. In addition, since the collector accommodation efficiency is increased, the efficiency of the transfer work is also improved.

  As an example, the discharge gate includes a double-opening type having a pair of gate members pivotally supported by a pair of rotation center axes that are symmetric with respect to the center line of the storage portion at a position above the lower end opening of the storage portion. You may comprise. In this configuration, even if dust accumulates in the storage portion and a large load is applied to each gate member, the discharge gate can be stably opened. Further, since the discharge gate is of the double opening type, space saving can be achieved when the discharge gate is in the open state.

  It is preferable that a seal member that makes the storage part watertight is attached to the discharge gate.

  When this dust chute system is installed in a building such as an apartment house, general garbage containing moisture such as garbage is put into the chute. For this reason, by making the storage part watertight, water is not leaked from the storage part, and it is hygienic, and for example, it is prevented that water splashes on electrical parts, leading to failure and the like. The operational stability of the system is ensured.

  The storage part is a divided structure composed of an upper container part and a lower container part that are stacked one above the other, and the upper container part is disposed at the lower peripheral edge of the upper container part with respect to the upper end opening of the lower container part. It is good also as providing the internal fitting part fitted.

  For example, even if there is an interfering object such as a beam in the middle of carrying the waste storage and discharge means to the installation position, the storage part has a split structure, so it is possible to carry in the state in which the storage part is divided and made smaller. Thereby, the storage section can be easily installed in a relatively narrow space.

  Further, as described above, it is desirable that the storage part is watertight, but by providing an inner fitting part at the lower peripheral edge of the upper container part and fitting the inner fitting part into the upper end opening of the lower container part. Even if the sealing member or the like is not provided at the division position of the upper container part and the lower container part, the storage part is kept watertight.

  The dust chute system is disposed between the dust storage and discharge means and the collector, and when discharging dust from the storage portion to the collector, between the lower end opening of the storage portion and the upper end opening of the collector. It is good also as providing the anti-scattering cover surrounding the space.

  When the space between the lower end opening of the storage unit and the upper end opening of the collector is surrounded by the anti-scattering cover, the dust is reliably accommodated in the collector when discharging the waste from the storage unit to the collector. Therefore, it is hygienic with no dust scattering.

  The dust chute system includes a gate driving unit that opens and closes the discharge gate, an operation switch, a collector detection unit that detects that the collector is disposed at the dust storage position, and a detection from the collector detection unit. Control means for driving the gate driving means to open the discharge gate when receiving both the signal and the operation signal from the operation switch may be provided.

  By doing so, the discharge gate can be opened and closed by operating the operation switch, so that it is not necessary to touch the waste storage and discharge means for storing the waste, which is hygienic. In addition, in a state where the collector is not disposed at the waste storage position, even if the operation switch is turned on, the discharge gate does not open, so that the waste discharged from the storage unit is prevented from scattering.

  The dust chute system is disposed between the dust storage and discharge means and the collector, and when discharging dust from the storage unit to the collector, between the lower end opening of the storage unit and the upper end opening of the collector An anti-scattering cover that surrounds the space, and a manual operation lever, the anti-scattering cover is retracted upward to enable the collector to be disposed at the garbage storage position, and the storage unit is moved downward to move the storage part. A use mechanism that surrounds the space between the lower end opening of the collector and the upper end opening of the collector, a link mechanism that moves vertically between the cover position, and a cover detection means that detects that the scattering prevention cover is in the use position. The control means further includes a detection signal from the collector detection means and a detection signal from the cover detection means, and an operation signal from the operation switch. Occasionally, by driving the drive means opens the discharge gate may be.

  By doing so, the scattering prevention cover is manually moved between the use position and the retracted position, but since the movement is performed by the link mechanism, the scattering prevention cover can be moved with a small operating force.

  In addition, unless the operation lever is manually operated and the anti-scattering cover is positioned at the use position, the discharge gate will not open even if the operation button is turned on, so that the waste discharged from the reservoir may be scattered. To be prevented.

  Therefore, the hygienic aspect is further improved in combination with the arrangement of the collector in the waste storage position.

  The dust chute system further includes a waste amount detection unit that detects that a predetermined amount of waste is stored in the storage unit, and a notification unit that performs notification, and the control unit is detected by the waste amount detection unit. It is good also as notifying that the predetermined | prescribed amount of garbage stored in the said storage part with respect to the conveyance operator of the said collector by operating the said alerting | reporting means in response to a signal.

  In this way, since a predetermined amount of waste is stored in the storage unit, it is necessary to discharge the waste in the storage unit to the collector and transport the collector to the collector transporter. It becomes possible to do.

  The dust chute system is further provided with warning means attached to the vicinity of the charging port to give a warning, and the control means receives a detection signal from the dust amount detection means to activate the warning means, It is preferable to warn the input person that input of garbage is prohibited.

  In this way, since a predetermined amount of garbage is stored in the storage unit, it becomes possible to warn the waste input person that it is prohibited to input garbage any more.

  As described above, according to the present invention, when the waste storage / discharging means is attached to the lower end of the chute, the waste falling in the chute is temporarily stored in the storage portion, and a predetermined amount of waste is stored in the storage portion. Opening the discharge gate and discharging the waste in the reservoir into the collector at a time makes it possible to deposit the dust uniformly in the collector, eliminating the need to flatten the waste in the collector manually, The safety and hygiene aspects can be improved, and the efficiency of carrying work can be improved by increasing the storage efficiency of the collector.

The upper end opening of the collector 21 is closed by the lid body 24 during movement (see FIG. On the other hand, when the collector 21 is disposed at a lower position of the chute 11 (hereinafter, this position is referred to as a garbage receiving position of the collector 21), the collector 21 is opened (see the solid line in FIG. 2). .

  In this dust chute system S, an empty collector 21 is disposed in advance in a dust storage position, and the dust that has been thrown in from the inlet 12 and discharged from the lower end opening of the chute 11 will be described in detail later. It will be accommodated in the collector 21. Then, the collector 21 filled with waste is transported to a predetermined collection site 13 by a transport worker (see the broken arrow in FIG. 1), where the waste is discarded. The empty collector 21 is again transported by the transport worker and placed at the waste storage position (see the solid arrow in FIG. 1). In such a manner, garbage is collected from each of the buildings B1, B2, and B3.

  In the present embodiment, the dust chute system S further includes a dust storage / discharge means 3 attached to the lower end of the chute 11, and a scattering prevention cover 4 disposed between the dust storage / discharge means 3 and the collector 21. I have.

  As shown in FIGS. 2 to 4, the waste storage / discharge means 3 includes a storage portion 31 for temporarily storing waste, and a discharge gate 32 for opening and closing the lower end opening 34 of the storage portion 31. 3 is supported by a frame 5 installed below the chute 11. In the following, the left side in FIG. 2 is referred to as left, the right side in FIG. 2 is referred to as right, and the left and right direction of the paper is referred to as the left and right direction, and the left side in FIG. Called the direction.

  A concave portion 14 in which the collector 21 is disposed is formed on the ground corresponding to the lower side of the chute 11, that is, corresponding to the garbage receiving position of the collector 21, and the frame 5 surrounds the concave portion 14. , Four leg portions 51, 51,... Arranged at predetermined intervals on the front, rear, left and right, and container support portions 52 that span the upper ends of two adjacent leg portions 51, 51 in the front-rear direction or the left-right direction. 52,..., And link support portions 53, 53 that span the intermediate portions of the two leg portions 51, 51 arranged at a predetermined interval in the front-rear direction, and a predetermined interval in the front-rear direction. Front and rear reinforcing portions 54 and 54 that span the lower portions of the two leg portions 51 and 51 arranged in the front-rear direction. Further, the lower portions of the two leg portions 51, 51 arranged at a predetermined interval in the left-right direction on the rear side of the frame 5 are spanned in the left-right direction by a left-right reinforcing portion, although not shown. There is no such reinforcing portion at the lower part of the two leg portions 51, 51 arranged at a predetermined interval in the left-right direction on the front side of the frame, and is arranged at a predetermined interval in the left-right direction on the front side of the frame 5. A space between the two leg portions 51 and 51 is a loading / unloading port for carrying the collector 21 into and out of the garbage storage position.

  Each of the front and rear reinforcing portions 54 is attached with a guide 56 that contacts the left and right side surfaces of the collector 21 and positions the collector 21 in the left and right direction. The guide 56 is positioned by the adjuster mechanism 57 in the left and right direction. Has been made adjustable. By doing so, even if the size (the width on the left and right) of the collector 21 is different, it is possible to position the collector 21 at the dust accommodating position by adjusting the position of the guide 56. That is, versatility increases. The positioning of the collector 21 in the front-rear direction is performed by the recessed portion 14 described above. That is, as shown in FIG. 3, the wheels 23, 23 arranged on the rear side of the collector 21 abut on the step of the recessed portion 14, whereby the collector 21 is positioned in the front-rear direction.

  The reservoir 31 is a substantially rectangular box including a front wall, a rear wall, and left and right side walls, the volume of which is the same as or smaller than the volume of the collector 21, Are fixed to the container support portions 52, 52,... Of the frame 5 via support brackets 31a, 31a,.

  An opening is formed in each of the upper end portion and the lower end portion of the storage portion 31, and the upper end opening therein is closed by the lid portion 33, while as shown in FIGS. A lower end opening 34 having a substantially arc shape when viewed from the rear and having an opening area substantially equal to or smaller than the upper end opening of the collector 21 can be opened and closed by a discharge gate 32 described later.

  The storage portion 31 is illustrated with both flanges 35a and 36a in a state in which an upper container portion 35 having a flange 35a formed at the lower end thereof and a lower container portion 36 having a flange 36a formed at the upper end thereof are vertically stacked. As shown in FIG. 5, the lower end of the upper container part 35 protrudes below the flange 35a and is fixed to the lower container by means of a fixing means (for example, a bolt or a nut). An internal fitting portion 35 b is formed that is fitted into the upper end opening of the portion 36. By making the storage part 31 into a divided structure of the upper container part 35 and the lower container part 36, even if there is an interference such as a beam in the middle of carrying the waste storage and discharge means 3 into the installation position, the upper container It is possible to divide into the part 35 and the lower container part 36, and to carry in in the state reduced in size, Thereby, the storage part 31 can be easily installed in a comparatively narrow space. Further, by providing the inner fitting portion 35b in the upper container portion 35, water or the like leaks from the storage portion 31 even if no sealing member or the like is interposed between the upper container portion 35 and the lower container portion 36. There is no.

  Further, maintenance windows 35 c are formed on the front and rear walls of the upper container portion 35.

  As described above, the storage unit 31 temporarily stores waste, and the left and right side walls thereof are each provided with a dust amount detection sensor 61 that detects that the waste in the storage unit 31 has reached a predetermined amount. (Not shown in FIG. 4). The dust amount detection sensor 61 is preferably, for example, a microwave sensor. By doing so, it is possible to accurately detect that the dust in the storage unit 31 has reached a predetermined amount without being affected by moisture or blind spots. It becomes possible to do. The dust amount detection sensor 61 is not limited to the microwave sensor.

  In the present embodiment, the discharge gate 32 extends in the front-rear direction across the front wall and the rear wall of the storage portion 31, and corresponds to the substantially arc-shaped lower end opening 34 of the storage portion 31 in front view. A pair of arcuate gate members 37, 37 formed in an approximately arcuate shape is provided.

  As shown in FIGS. 2, 3, and 6, each arcuate gate member 37 is provided with a pivotal support portion 38 having a substantially sector shape in front view at the front and rear ends thereof. The central part of the support part 38 is centered on rotation center axes X1 and X2 that are set symmetrically with respect to the center line C in the left-right direction at intermediate positions in the vertical direction on the front wall and the rear wall of the storage part 31, respectively. On the other hand, it is pivotally supported via a bearing. As a result, the pair of arc-shaped gate members 37 are rotatable along arcs centered on the rotation center axes X1 and X2 at the respective positions on both sides of the center line C.

  The pair of arcuate gate members 37 are rotationally driven by gate driving means. In this embodiment, the gate driving means is a pair of motor cylinders 30 and 30 controlled by the controller 6 described later, but is not limited to this, and various actuators are employed as the gate driving means. It is possible.

  Each motor cylinder 30 has an upper end of the cylinder portion fixed to the left and right side walls of the upper container portion 35 via brackets 35 d and 35 d, while a tip of the rod is in the front-rear direction of each arcuate gate member 37. The arcuate gate member 37 is pivotally fixed around an axis extending in the front-rear direction with respect to the central portion, whereby each arcuate gate member 37 is arcuate around the rotation center axes X1 and X2 as the motor cylinders 30 extend and retract. To turn. Thus, the discharge gate 32 is opened at the lower end of the storage portion 31 when the side surfaces (hereinafter referred to as the mating surfaces 37a) of the pair of arcuate gate members 37 abut each other on the left and right center line C of the storage portion 31. 34 (see the two-dot chain line in FIG. 6 and FIG. 2), and the mating surface 37a of each arcuate gate member is located in the vicinity of the left and right side walls of the storage portion 31 to open the lower end opening 34 ( 6) (see the solid line in FIG. 6).

  As shown in FIG. 7, a seal member 39 is attached to the mating surface 37a of the left arcuate gate member 37 of the pair of arcuate gate members 37, so that the reservoir 31 is watertight. It is configured. With this configuration, for example, when garbage containing moisture such as raw garbage is stored in the storage unit 31, water does not leak from the storage unit 31, which is particularly preferable as a dust chute system S for an apartment house or the like.

  In this embodiment, the seal member 39 includes a fixed portion 39a fixed to the mating surface 37a, a seal main body 39b that is continuous with the fixed portion 39a and is formed in a hollow shape having a substantially circular cross section, and the seal main body 39b. Are provided with a plurality of (three in the illustrated example) protrusions 39c, 39c,..., And this structure provides particularly excellent watertightness. The material of the seal member 39 is not particularly limited, but may be natural rubber or synthetic rubber such as EPDM. For example, the sealing member 39 can be made of urethane resin. In this case, high sealing performance can be obtained, which is particularly preferable.

  As shown in FIGS. 2 to 4, the lid 33 is connected to the lower end opening of the chute 11 and is formed with a circular through hole 33 a penetrating the lid 33 up and down. The reservoir 31 communicates with each other through the through hole 33a.

  The lid 33 also has a built-in gate 7 for opening and closing the through hole 33a. This insertion gate 7 supports a pair of flat gate members 71, 71 disposed on both sides of the center line with respect to the front-rear direction of the through-hole 33 a and the left side of each flat gate member 71. Support 72 for guiding the sliding movement of the gate member 71 in the front-rear direction, and the bearings 73, 73 supported by the bearings 73, 73 at the right side position with respect to each flat gate member 71. , A slider 75, 75 fixed to the right side of each flat gate member 71 and screwed into the ball screw 74, and a controller, which will be described later, attached to the front end of the ball screw 74. And an opening / closing motor 76 that rotates the ball screw 74 around its central axis.

  As shown in FIG. 4, the ball screw 74 is threaded in the opposite direction between the front portion F and the rear portion R sandwiching the center corresponding to the center line with respect to the front-rear direction of the through-hole 33a. Thus, when the ball screw 74 is rotated by driving the opening / closing motor 76, the sliders 75 and 75 are engaged with the front portion F of the ball screw 74, and the slider is engaged with the rear portion R. 75 and 75 move in opposite directions. Thus, the insertion gate 7 has a state in which the side surfaces of the pair of flat gate members 71 are in contact with each other on the center line of the through hole 33a (see FIG. 4) and each flat plate shape. The state in which the side surface of the gate member 71 is located in the vicinity of the front and rear edges of the through hole 33a and the through hole 33a is opened (see FIG. 3) can be switched. In this way, by making the input gate 7 a double-open type having a pair of flat gate members 71, it is possible to save space when the input gate 7 is opened.

  By making the material of the sliders 75, 75 relatively soft with respect to the material of the ball screw 74, it is possible to eliminate the biting and eliminate the need for lubricating oil. This is an advantageous configuration in the dust chute system S that may be fixed by dust or dust. As an example, the ball screw 74 may be made of stainless steel in consideration of corrosion resistance, while the sliders 75 and 75 may be made of brass.

  In addition, since the lower end opening 34 of the storage part 31 is opened and closed by the discharge gate 32, the input gate 7 can be omitted.

  The scattering prevention cover 4 covers the lower end portion of the storage portion 31, a main body portion 41 that is tapered downward, and a rubber bellows portion that is hung from the lower end of the main body portion 41 and extends downward. 42.

  The anti-scattering cover 4 is supported by the frame 5 via a pair of link mechanisms 8 (not shown in FIG. 4) disposed on the left and right sides of the anti-scattering cover 4. Each link mechanism 8 is movable in the vertical direction.

  As shown in FIGS. 3 and 8, each link mechanism 8 includes first and second links 81 and 82 that are pivotally coupled to each other at the center thereof and extend in the front-rear direction. While being pivotally coupled to the rear portion of the link support portion 53 of the frame 5, a roller 81 a is attached to the front end of the frame 5, and the lower surface of the contact portion 43 formed at the front portion of the side surface of the main body portion 41. It is in contact. The rear end of the second link 82 is pivotally coupled to the rear portion of the side surface of the main body 41, and a roller 82 a is attached to the front end of the second link 82 so as to be formed at the front portion of the link support portion 53 of the frame 5. The contact portion 58 is in contact with the upper surface of the contact portion 58. The roller 82a is also pressed downward by a pressing member 59 fixed to the link support portion 53, so that the roller 82a can move only in the front-rear direction.

  The link mechanism 8 is also provided with an operation lever 83 that is operated by a transport worker, and the operation lever 83 is a bent portion whose base end is bent. The bent portion is pivotally coupled to the link support portion 53 of the frame 5, and a connecting link 84 is pivotally coupled to the bent end portion. The connecting link 84 is pivotally coupled to a portion of the first link 81 between the pivotally supporting portion with the second link and the roller 81a. The front end portion of the operation lever 83 protrudes forward from the frame 5, and the front end portions of the left and right operation levers 83, 83 are connected to each other by a handle 85 gripped by the transport operator (see FIG. 4). .

  As shown by the solid line in FIG. 8, the scattering prevention cover 4 is positioned above the link mechanism 8 in this configuration when the operation lever 83 is substantially horizontal (the two-dot chain line in FIG. 8 and FIG. 3). When the operation lever 83 is rotated upward while the lower end of the bellows portion 42 is positioned above the collector 21 (the retracted position of the anti-scattering cover 4), as shown by the one-dot chain line in FIG. When the bent end portion of the operation lever 83 moves rearward, the front end portion of the first link 81 is pulled downward and the rear end portion of the second link 82 pivotally coupled to the first link 81 Moves downward. As a result, the scattering prevention cover 4 moves downward (see the one-dot chain line in FIG. 8). In this state, the lower end of the bellows portion 42 is positioned in the upper end opening of the collector 21, and the scattering prevention cover 4 surrounds the space between the lower end opening 34 of the storage portion 31 and the upper end opening of the collector 21 ( As described later, when the discharge gate 32 is opened and the waste in the storage portion 31 is discharged to the collector 21, as will be described later, the dust is surely stored in the collector 21 and the dust is scattered. Absent.

  Next, a configuration relating to control of the dust chute system S will be described with reference to FIGS. In the figure, reference numeral 6 denotes a controller that performs overall control of the system S. For this controller 6, it is detected that the collector 21 is disposed at the waste accommodating position, for example, for the frame 5. A collector sensor 62 composed of a fixed phototube, a cover sensor 63 composed of a limit switch attached to the link mechanism 8 for detecting that the anti-scattering cover 4 is in the use position, and an open / closed state of the discharge gate 32, for example. Detecting, for example, a discharge gate sensor 64 including a limit switch built in each motor cylinder 30, a closing gate sensor 65 including, for example, a limit switch for detecting an open / closed state of the closing gate 7, and garbage in the storage unit 31. From each of the waste amount detection sensors 61 that detect that the predetermined amount has been reached. Detection signal is input. Although not shown, the controller 6 is attached to a predetermined position, and an operation signal is input from an operation switch 66 operated by a transport worker.

  The controller 6 includes a caution lamp 67 attached in the vicinity of each input port 12, a rotating lamp 68 and a buzzer 69 attached in the vicinity of the installation position of the waste storage / discharge means 3, and an open / close gate 7. The opening / closing motor 76 for controlling the motor and the motor cylinders 30, 30 for opening / closing the discharge gate 32 are connected to each other, and the controller 6 outputs a drive signal to each of these devices.

  Next, the operation of the dust chute system S will be described with reference to FIGS. First, at the normal time, the input gate 7 is opened while the discharge gate 32 is closed (see P1 in FIG. 10). As a result, the garbage introduced from the inlet 12 falls in the chute 11 and is stored in the storage unit 31. Then, when a predetermined amount of garbage accumulates in the storage unit 31, this is detected by the dust amount detection sensor 61, and the detection signal is output to the controller 6.

  The controller 6 receives the detection signal from the waste amount detection sensor 61 and turns on the caution lamp 67 to warn the waste thrower that the introduction of the waste is prohibited, and at the same time the rotating lamp 68. Is turned on and the operation of the buzzer 69 is performed to notify the conveying worker that a predetermined amount of garbage has accumulated in the storage unit 31. Further, the controller 6 drives an opening / closing motor 76 to close the closing gate 7. Thereby, as described above, the pair of flat gate members 71 and 71 are moved, and the closing gate 7 is closed.

  The transport operator performs an operation of rotating the operation lever 83 upward in a state where the collector 21 is disposed at the garbage storage position, thereby moving the anti-scattering cover 4 downward, so that the anti-scattering cover 4 is moved. Set to the use position. By doing so, a detection signal is output from the cover sensor 63 to the controller 6. Further, since the collector 21 is arranged at a predetermined position, a detection signal is also output from the collector sensor 62 to the controller 6 (see P2).

  In this state, when the transport operator turns on the operation switch 66, an operation signal is output from the operation switch 66 to the controller 6.

  When receiving the operation signal, the controller 6 determines whether or not detection signals from the collector sensor 62 and the cover sensor 63 are input. When the detection signals from the collector sensor 62 and the cover sensor 63 are not input, the drive signals are not output to the motor cylinders 30 and 30. Accordingly, the discharge gate 32 is not opened when the collector 21 is not disposed at the dust storage position and / or when the anti-scattering cover 4 is not at the use position.

  On the other hand, when the detection signals from the collector sensor 62 and the cover sensor 63 are input, the controller 6 outputs a drive signal to the motor cylinders 30 and 30. As a result, as described above, the pair of arcuate gate members 37 rotate to open the lower end opening 34 of the storage portion 31. As a result, the waste stored in the storage part 31 is discharged | emitted in the collector 21 at once (refer P3).

  When the waste in the storage unit 31 is discharged to the collector 21, a non-detection signal is output from the dust detection sensor 61, and the controller 6 receives the signal and drives the motor cylinders 30 and 30. A signal is output and the discharge gate 32 is closed. At the same time or after a time difference, a drive signal is output to the opening / closing motor 76, and the closing gate 7 is opened (see P4).

  After the dust is accommodated in the collector 21, the operation lever 83 is rotated downward, thereby bringing the anti-scattering cover 4 into the retracted position and then being carried out of the dust accommodating position. As shown, the collector 21 storing the waste is transported by the transport worker, and the emptied collector 21 is again disposed at the waste storage position (see P5).

  Here, when a predetermined amount of dust has accumulated in the storage unit 31, that is, when the rotating lamp 68 is turned on or the buzzer 69 is operated, the operation lever 83 is operated to prevent the scattering prevention cover 4 from being operated. However, when the empty collector 21 is placed at a predetermined position (in the case of P5 described above), it is possible to operate the operation lever 83 and set the anti-scattering cover 4 to the use position in advance. Good.

  As described above, according to the dust chute system S according to the present embodiment, the dust storage / discharge means 3 is disposed between the chute 11 and the collector 21, so that the dust falling in the chute 11 is collected by the collector 21. After being temporarily stored in the storage unit 31 without being directly put into the storage unit 31, a predetermined amount of garbage (an amount substantially equal to the capacity of the collector 21) is discharged from the storage unit 31 to the collector 21 at a time.

  When the dust falling in the chute 11 is directly and intermittently introduced into the collector 21, the dust in the collector 21 is caused by the fact that the opening area of the chute 11 is smaller than the opening area of the collector 21. As a result, the storage efficiency of the collector 21 is lowered. In addition, it is necessary to flatten the mountainous garbage manually.

  However, in the dust chute system S according to the present embodiment, a predetermined amount of garbage once stored in the storage unit 31 is discharged to the collector 21 at a time from the lower end opening 34 of the storage unit 31 having a relatively large diameter. As a result, the dust can be uniformly accommodated in the collector 21, and the accommodation efficiency of the collector 21 is increased, and it is not necessary to level the dust. As a result, work efficiency can be improved and safety and hygiene can be improved.

  Further, by disposing the anti-scattering cover 4 between the storage unit 31 and the collector 21, when the waste is discharged from the storage unit 31 to the collector 21, the dust is prevented from scattering, and the garbage is collected in the collector. It is securely accommodated in 21. Thereby, a safety surface and a hygiene surface can be improved further.

  Furthermore, since the discharge gate 32 of the storage part 31 is a double-opening type provided with a pair of arc-shaped gate members 37, 37 that rotate in an arc around the rotation center axes X 1, X 2, dirt is stored in the storage part 31. Even when the arc-shaped gate member 37 is deposited and a load is applied thereto, the opening operation can be performed stably and reliably. Further, since the pair of arcuate gate members 37 and 37 rotate, it is possible to save space when the discharge gate 32 is opened.

  As described above, even if the operation switch 66 is turned on, the discharge gate 32 is not opened when the collector 21 is not disposed in the dust storage position and / or the scattering prevention cover 4 is not in the use position. Since the discharge gate 32 has an interlock function that opens the collector 21 only when the collector 21 is disposed at the dust storage position and the scattering prevention cover 4 is at the use position, no dust is thrown into the collector 21. It is possible to reliably prevent the splashing. This configuration is extremely effective in ensuring safety and hygiene, particularly in the dust chute system in which the collector 21 is manually conveyed and the scattering prevention cover 4 is manually moved up and down. It is a simple configuration.

(Other embodiments)
The present invention may be configured as follows for the above embodiment. That is, the scattering prevention cover 4 may not be configured to manually move up and down. For example, the scattering prevention cover 4 may be moved up and down in conjunction with the opening / closing operation of the discharge gate 32 by an actuator controlled by the controller 6. Further, the arrangement of the collector 21 at the garbage storage position and the conveyance of the collector 21 from the garbage storage position may be automatically performed in conjunction with the opening / closing operation of the discharge gate 32.

  As described above, the present invention is extremely useful as a dust chute system installed in a building such as an apartment house because the collector accommodation efficiency is increased and safety and hygiene can be improved. .
