Description

[Technical field]

[0001] The present invention relates to a waste treatment device, and more particularly to a waste treatment device for a railway vehicle. [Background technology]

[0002] Transportation facilities provided for long-distance travel, such as airplanes, buses, and trains, are equipped with toilets and waste tanks, in which passenger waste (including wastewater) is stored during travel (see, for example, Patent Document 1). The wastewater tank has a drain and a water inlet.

[0003] For railroad cars, waste is removed from the vehicle depot through a water supply and drainage system, which is used to supply water to a tank for cleaning. The removed waste is then discharged into a wastewater treatment tank installed on the ground.

[0004] In the prior art, the waste removal and tank water filling tasks were performed manually by workers. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7011693 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in a railway vehicle, multiple cars are connected together, and multiple waste tanks are located in the axial direction of the vehicle. As a result, the work area is also long in the axial direction of the vehicle, and relatively short in the direction perpendicular to the vehicle axis, and tends to be narrow.

[0007] In a small work area, it is difficult to handle the hoses, which is a burden for the workers. Other issues include the smell of waste and working in high temperatures in summer.

[0008] The present invention is intended to solve the above-mentioned problems, and provides an apparatus that replaces the work of removing waste and filling the tank with water, which has conventionally been performed manually by workers. [Means for solving the problem]

[0009] The present invention, which solves the above problems, provides a sewage treatment device for treating sewage in a sewage tank of a train, comprising a position identification mechanism for identifying the position of a discharge outlet or a water supply outlet of the sewage tank, a moving mechanism movable in the train travel direction, a sewage removal mechanism for removing sewage from the sewage tank, a tank water supply mechanism for supplying water to the sewage tank, and a control unit for controlling the operation of each mechanism.

[0010] This will replace the work of removing waste and filling the tank with water, which was previously done manually by workers.

[0011] In the above invention, preferably, the waste removal mechanism includes a waste removal hose moving mechanism which moves the waste removal hose back and forth toward the drain outlet, a connection mechanism which is provided at the tip of the waste removal hose and connects it to the drain outlet, and a cock opening / closing mechanism which opens and closes the cock of the drain outlet.

[0012] This can replace the waste removal work that was previously done manually by workers.

[0013] In the above invention, preferably, the tank water supply mechanism includes a cap removal mechanism for removing the cap of the water supply inlet, a water supply hose moving mechanism for moving the water supply hose back and forth toward the water supply inlet, a crimping mechanism for crimping the tip of the water supply hose, and a water supply mechanism for supplying water through the water supply hose.

[0014] This will replace the tank water supply work that was previously done manually by workers.

[0015] In the above invention, preferably, the control unit executes the following processes: a process of causing the position identification mechanism to identify the position of the drain outlet or water supply inlet; a process of causing the moving mechanism to move to correspond to the drain outlet or water supply inlet; a process of causing the waste removal mechanism to remove waste from the waste tank; and a process of causing the tank water supply mechanism to supply water to the waste tank in conjunction with the process of the waste removal mechanism.

[0016] This allows the waste removal task and the tank water supply task, which were previously separate tasks, to be performed as a single task.

[0017] In the above invention, preferably, the control unit executes the process of causing the waste removal hose moving mechanism to advance the waste removal hose toward the drain outlet, the process of causing the connection mechanism to connect the tip of the waste removal hose to the drain outlet, and the process of causing the cock opening / closing mechanism to open and close the cock of the drain outlet.

[0018] This allows a series of processes related to the waste removal operation to be carried out.

[0019] In the above invention, preferably, the control unit executes the following processes: causing the cap removal mechanism to remove the cap from the water supply inlet; causing the water supply hose moving mechanism to advance the water supply hose toward the water supply inlet; causing the crimping mechanism to crimp the tip of the water supply hose; and causing the water supply mechanism to supply water.

[0020] This allows a series of processes related to the tank water supply operation to be executed.

[0021] The present invention, which solves the above-mentioned problems, provides a waste removal device for removing waste from a waste tank of a train, comprising a position identification mechanism for identifying the position of a discharge outlet of the waste tank, a movement mechanism movable in the direction of train travel, a hose movement mechanism for moving a hose back and forth toward the discharge outlet, a connection mechanism provided at the tip of the hose for connection with the discharge outlet, a cock opening / closing mechanism for opening and closing a cock of the drain outlet, and a control unit for controlling the operation of each mechanism.

[0022] This can replace the waste removal work that was previously done manually by workers.

[0023] In the above invention, preferably, the control unit executes the following processes: having the position identification mechanism identify the position of the drain outlet; having the moving mechanism move the hose so that the drain outlet and the hose tip face each other; having the hose moving mechanism advance the hose toward the drain outlet; having the connection mechanism connect the hose tip and the drain outlet; and having the cock opening and closing mechanism open and close the cock of the drain outlet.

[0024] This allows a series of processes related to the waste removal operation to be carried out.

[0025] The present invention, which solves the above-mentioned problems, is a tank water supply device that supplies water to a train's sewage tank, and includes a position identification mechanism that identifies the position of the water supply inlet of the sewage tank, a moving mechanism that can move in the direction of train travel, a cap removal mechanism that removes the cap of the water supply inlet, a hose moving mechanism that moves a hose back and forth toward the water supply inlet, a crimping mechanism that crimps the tip of the hose, a water supply mechanism that supplies water through the hose, and a control unit that controls the operation of each mechanism.

[0026] This will replace the tank water supply work that was previously done manually by workers.

[0027] In the above invention, preferably, the control unit executes the following processes: having the position identification mechanism identify the position of the water supply inlet; having the moving mechanism move the water supply inlet and the cap removal mechanism so that they face each other; having the cap removal mechanism remove the cap of the water supply inlet; having the hose moving mechanism advance the hose toward the water supply inlet; having the crimping mechanism crimp the tip of the hose; and having the water supply mechanism supply water.

[0028] This allows a series of processes related to the tank water supply operation to be executed. Effect of the Invention

[0029] The device of the present invention can replace the work of removing waste and filling the tank with water, which has traditionally been done manually by workers, and as a result, the burden on workers can be significantly reduced and the work time can be significantly shortened.

[0030] Furthermore, no modifications to the railway vehicles are required, and this technology can be applied immediately. [Brief description of the drawings]

[0032] First Embodiment ~Configuration~

[0033] FIG. 1 is a diagram showing the configuration of a waste removal device, including a front view and a side view.

[0034] The waste remover 1 comprises a position identifying mechanism 10, a lower moving mechanism 20, an upper moving mechanism 30, a discharge port connecting mechanism 40, a cock opening / closing mechanism 50, and a control unit 100.

[0035] The position identification mechanism 10 identifies the position of the waste tank discharge outlet 6. In the illustrated example, it is composed of two arms 11, 11 and a link mechanism. When the arms open and a reaction force is applied to the inner wall of the waste tank box, the center of the discharge outlet 6 and the center of the waste removal hose coincide with each other.

[0036] In recent years, image analysis technology using cameras has advanced, and this may be used to identify the position of the discharge outlet 6 of the waste tank.

[0037] The lower movement mechanism 20 allows the entire device to move. In the illustrated example, when the two arms receive a reaction force from the inner wall of the waste tank box, the wheels move in the longitudinal direction of the train following the movement of the arms. The lower movement mechanism 20 has a stopping section. When the stopping section is activated, the movement is restricted by interaction with the device's own weight. In addition, the device does not generally move in the direction perpendicular to the train (short side of the train).

[0038] The upper moving mechanism 30 moves the upper mechanism (including the waste removal hose, the discharge port connection mechanism 40, and the cock opening and closing mechanism 50) back and forth in the discharge port direction (direction perpendicular to the train) relative to the lower moving mechanism. For example, rails 31 are provided on the top of a support erected from the lower moving mechanism 20, and the upper mechanism moves via the rails 31.

[0039] The discharge port connection mechanism 40 is provided at the tip of the waste removal hose and connects to the discharge port 6 .

[0040] 2 is a configuration diagram of the outlet connection mechanism 40. It is a front view and a side view. The outlet connection mechanism 40 is made up of a rotating part 41, a rotating striking part 42, a striking receiving part 43, and a screw part 44.

[0041] The rotating part 41 rotates the rotating striking part 42 around the hose. The striking part 43 is provided integrally with the threaded part 44. The rotating striking part 42 rotates and collides with the striking part 43. The striking part 43 rotates due to the reaction force, and the threaded part 44 screws into the threaded part inside the discharge port 6.

[0042] This connects the waste removal hose to the outlet 6. Connection by other means may also be used.

[0043] Furthermore, when the rotating part 41 rotates the rotary impact part 42 in the opposite direction, the screw thread is released and the connection is released.

[0044] The cock opening / closing mechanism 50 opens and closes the cock of the drain outlet 6 .

[0045] 3 is an explanatory diagram of the operation of the cock opening and closing mechanism 50. It is a front view and a side view of the cock open state and the cock closed state. The cock opening and closing mechanism 50 is made up of a reciprocating part 51, a link part 52, and a rotating part 53.

[0046] The reciprocating unit 51 causes the cylinder to reciprocate. The reciprocating unit 51 is linked to a rotating unit 53 via a link unit 52. That is, the reciprocating motion is converted into rotation via the link.

[0047] The rotating portion 53 has a cock gripping portion, and rotates from the cock open state to the cock closed state, or from the cock closed state to the cock open state.

[0048] The control unit 100 controls the operations of the position identification mechanism 10 , the lower movement mechanism 20 , the upper movement mechanism 30 , the discharge port connection mechanism 40 , and the cock opening and closing mechanism 50 .

[0049] 4 is a functional block diagram of the control unit 100. The control unit 100 has a position identification unit 101, a lower movement unit 102, an upper movement unit 103, a discharge port connection unit 104, and a cock opening / closing unit 105.

[0050] The position identification unit 101 controls the operation of the position identification mechanism 10. The lower movement unit 102 controls the operation of the lower movement mechanism 20 in conjunction with the processing of the position identification unit 101. The upper movement unit 103 controls the operation of the upper movement mechanism 30 after the processing of the lower movement unit 102. The discharge port connection unit 104 controls the operation of the discharge port connection mechanism 40 after the processing of the upper movement unit 103 or in conjunction with it. The cock opening / closing unit 105 controls the operation of the cock opening / closing mechanism 50 after the processing of the discharge port connection unit 104.

[0051] ~Operation~ 5 is a flow chart showing the operation control by the control unit 100. The operation will be described based on the flow.

[0052] The position identifying mechanism 10 identifies the position of the discharge outlet 6 of the waste tank (step S11).

[0053] After the position is specified, the lower movement mechanism 20 moves in the longitudinal direction of the train so that the center of the discharge port 6 coincides with the center of the waste removal hose, and then stops (step S12).

[0054] After the lower moving mechanism is stopped, the upper moving mechanism 30 advances the upper mechanism including the waste removal hose toward the discharge port (step S13). As a result, the tip of the waste removal hose and the discharge port 6 come close to each other.

[0055] After the waste removal hose is placed in a predetermined position, the discharge port connection mechanism 40 connects the waste removal hose to the discharge port 6 (step S14).

[0056] After the connection is complete, the cock opening and closing mechanism 50 changes from the cock closed state to the cock open state (step S15).

[0057] This allows communication between the inside and outside of the sewage tank, and the sewage in the tank flows naturally downward via the sewage drainage hose.

[0058] The waste removal operation is terminated based on the appropriate time elapsed based on past experience, a remaining amount sensor (numbering omitted) installed in the tank, a flow meter (numbering omitted) installed at the discharge outlet, and other judgment indicators (step S16).

[0059] The cock opening / closing mechanism 50 changes from the cock open state to the cock closed state (step S17), thereby isolating the inside and the outside of the waste tank from each other.

[0060] After the cock is closed, the discharge port connection mechanism 40 releases the connection between the waste removal hose and the discharge port 6 (step S18).

[0061] After the connection is released, the upper moving mechanism 30 moves the upper mechanism including the waste removal hose back from the discharge port (step S19).

[0062] The car may wait in this state for the next waste removal, or the lower moving mechanism 20 may be released from the restraint and moved to an appropriate position in the longitudinal direction of the train.

[0063] ~Effects~ The device of the present invention can execute a series of operations related to the waste removal work that was previously done manually by workers, which can significantly reduce the burden on workers and shorten the work time.

[0064] In the device of the present invention, movement in the longitudinal direction of the train is limited. Meanwhile, the upper moving mechanism 30 and the cock opening and closing mechanism 50 operate perpendicular to the train. In particular, the cock opening and closing mechanism 50 converts reciprocating motion into rotation. The discharge port connection mechanism 40 rotates around the hose axis. These series of movements do not interfere with each other even in a narrow range.

[0065] This eliminates the need for hose management, allowing for effective use of small work areas.

[0066] <Second embodiment> ~Configuration~ Fig. 6 is a configuration diagram of the tank water supply device, including a front view and a side view.

[0067] The tank water supply device 2 is composed of a position identification mechanism (numbering omitted), a lower movement mechanism 60, a cap removal mechanism 70, an upper movement mechanism 80, a tightening mechanism 90, a control unit 110, and a water supply mechanism (numbering omitted).

[0068] The position identifying mechanism identifies the position of the water supply port 7 of the waste tank. Since the position identifying mechanism 10 of the waste extractor 1 can be used for other purposes, details thereof will be omitted.

[0069] The lower movement mechanism 60 allows the entire device to move. The wheels move in the longitudinal direction of the train in conjunction with the position identification mechanism. The lower movement mechanism 20 has a stopper. When the stopper is activated, movement is restricted by interaction with the device's own weight. In addition, the device does not generally move in the direction perpendicular to the train (short side of the train).

[0070] The cap removal mechanism 70 is provided parallel to the top and bottom of the water supply hose, and removes the cap 8 of the water supply port 7.

[0071] 7 is a side view showing the configuration and operation of the cap removal mechanism 70. The upper view shows the state immediately before removal, and the lower view shows the state when the cap is being held.

[0072] The cap removal mechanism 70 comprises a reciprocating portion 71 , a link portion 72 , a lower jaw portion 73 , and an upper jaw portion 74 .

[0073] The reciprocating part 71 causes the cylinder to reciprocate. The reciprocating part 71 is linked to an upper jaw part 74 via a link part 72. That is, the reciprocating motion is converted into rotation via the link.

[0074] The lower jaw 73 and the upper jaw 74 are arranged side by side, one above the other. The lower jaw 73 is fixed, whereas the upper jaw 74 rotates. With the lower jaw 73 holding down the lower side of the cap 8, the upper jaw 74 rotates and holds down the upper side of the cap 8, thereby sandwiching the cap 8.

[0075] 8 is another explanatory diagram of the operation of the cap removal mechanism 70. Up-down and back-and-forth movements are indicated by arrows. The cap removal mechanism 70 and the water supply hose are provided parallel to one another and can move up and down so as to face the water supply port 7. The lower jaw 73 can also move back and forth so as to be positioned below the cap 8 and to remove the clamped cap 8.

[0076] The cap removal mechanism 70 may move up and down or back and forth in conjunction with the upper movement mechanism 80, or the cap removal mechanism 70 may operate independently.

[0077] The upper moving mechanism 80 moves the upper mechanism (including the water supply hose, cap removal mechanism 70, and tightening mechanism 90) back and forth in the water supply port direction (direction perpendicular to the train) relative to the lower moving mechanism. For example, rails 81 are provided on the top of the pillars erected from the lower moving mechanism 60, and the upper mechanism moves via the rails 81.

[0078] The crimping mechanism 90 is provided on the tip side of the hose and crimps the tip of the hose.

[0079] 9 is a configuration diagram of the tightening mechanism 90. A front view and a plan view are shown. The tightening mechanism 90 is made up of a reciprocating part 91, a link part 92, and a tightening part 93.

[0080] The reciprocating part 91 causes the cylinder to reciprocate. The reciprocating part 91 is linked to a tightening part 93 via a link part 92. That is, the reciprocating motion is converted into rotation via the link.

[0081] The tightening portion 93 consists of a right half and a left half, and as the two halves rotate, the tips of the halves move closer or farther apart. When the tips move closer to each other, the tightening portion 93 tightens the hose tip, and when the tips move away from each other, the tightening portion 93 loosens the hose tip.

[0082] The control unit 110 controls the operations of the position identification mechanism (numbering omitted), the lower movement mechanism 60, the cap removal mechanism 70, the upper movement mechanism 80, and the tightening mechanism 90.

[0083] 10 is a functional block diagram of the control unit 110. The control unit 110 has a position identification unit 111, a lower movement unit 112, a cap removal unit 113, an upper movement unit 114, a tightening unit 115, and a water supply unit .

[0084] The position identification unit 111 controls the operation of the position identification mechanism. The lower movement unit 112 controls the operation of the lower movement mechanism 60 in conjunction with the processing of the position identification unit 101. The cap removal unit 113 controls the operation of the cap removal mechanism 70 after the processing of the lower movement unit 112. The upper movement unit 114 controls the operation of the upper movement mechanism 80 after the processing of the cap removal unit 113 or in conjunction with it. The crimping unit 115 controls the operation of the crimping mechanism 90 after the processing of the upper movement unit 114. The water supply unit 116 controls the operation of the water supply mechanism after the processing of the crimping unit 115.

[0085] ~Operation~ 11 is a flow chart showing operation control by the control unit 110. The operation will be described based on the flow.

[0086] The position identification mechanism (numbering omitted) identifies the position of the water supply port 7 of the waste tank (step S21).

[0087] After the position is specified, the lower moving mechanism 60 moves in the longitudinal direction of the train so that the water supply port 7 and the cap removal mechanism 70 face each other, and then stops (step S22).

[0088] After the lower moving mechanism is stopped, the cap removing mechanism 70 moves to the cap of the water supply port 7 and removes the cap (step S23). The cap removing mechanism 70 descends while holding the cap, and leaves in front of the water supply port 7.

[0089] After removing the cap, upper movement mechanism 30 lowers the water supply hose so that the water supply port 7 and the water supply hose face each other, and then advances the water supply hose toward the water supply port to attach the hose to the water supply port (step S24).

[0090] After the hose is attached to the water supply port, the crimping mechanism 90 crimps the end of the hose (step S25), thereby connecting the inside and outside of the waste tank, and the water supply mechanism starts supplying water via the water supply hose.

[0091] The water supply operation is terminated based on the appropriate time elapsed based on past experience, a capacity sensor (numbering omitted) provided in the tank, a flow meter (numbering omitted) provided in the water supply port, and other judgment indicators (step S26).

[0092] When the water supply operation is completed, the tightening mechanism 90 loosens the tightening of the hose tip (step S27), and the upper movement mechanism 30 moves the water supply hose back from the water supply port and removes the hose from the water supply port. Furthermore, the water supply hose is raised (step S28). The hose leaves in front of the water supply port 7.

[0093] The cap removal mechanism 70 moves to the cap of the water supply port 7 and attaches the cap (step S29).

[0094] The lower moving mechanism 60 may wait in this state for the next waste removal, or the lower moving mechanism 60 may be released and moved to an appropriate position in the longitudinal direction of the train. ~Effects~

[0095] The device of the present invention can execute a series of operations related to tank water supply work that was previously performed manually by workers. This significantly reduces the burden on workers, and as a result, shortens the work time.

[0096] In the present device, movement in the longitudinal direction of the train is limited. Meanwhile, the cap removal mechanism 70, the upper moving mechanism 80, and the tightening mechanism 90 operate perpendicular to the train. In particular, the cap removal mechanism 70 and the tightening mechanism 90 convert reciprocating motion into rotation. This series of movements does not interfere with each other even in a narrow range.

[0097] This eliminates the need for hose management, allowing for effective use of small work areas.

[0098] <Third embodiment> ~Configuration~ 12 is a configuration diagram of a waste disposal device, showing a front view and a side view.

[0099] The waste disposal device 3 has both the main functions of the waste extractor 1 and the main functions of the tank water supply device 2. Specifically, it is composed of a position identification mechanism 10, a lower movement mechanism 20, an upper movement mechanism 30, a discharge port connection mechanism 40, a cock opening and closing mechanism 50, a cap removal mechanism 70, an upper movement mechanism 80, a tightening mechanism 90, a control unit 120, and a water supply mechanism (numbering omitted).

[0100] The same configurations as those in the first and second embodiments (including similarities) are assigned the same numbers. Unless otherwise specified, the details of each configuration will be referred to the first and second embodiments.

[0101] The control unit 120 controls the operations of the position identification mechanism 10, the lower movement mechanism 20, the upper movement mechanism 30, the outlet connection mechanism 40, the cock opening and closing mechanism 50, the cap removal mechanism 70, the upper movement mechanism 80, and the tightening mechanism 90.

[0102] 13 is a functional block diagram of the control unit 120. The control unit 120 has a position identification unit 101, a lower movement unit 102, an upper movement unit 103, a discharge port connection unit 104, a cock opening / closing unit 105, a cap removal unit 113, an upper movement unit 114, a tightening unit 115, and a water supply unit 116.

[0103] The position identification unit 101 controls the operation of the position identification mechanism 10. The lower movement unit 102 controls the operation of the lower movement mechanism 20 in conjunction with the processing of the position identification unit 101. The upper movement unit 103 controls the operation of the upper movement mechanism 30 after the processing of the lower movement unit 102. The discharge port connection unit 104 controls the operation of the discharge port connection mechanism 40 after the processing of the upper movement unit 103 or in conjunction with it. The cock opening / closing unit 105 controls the operation of the cock opening / closing mechanism 50 after the processing of the discharge port connection unit 104.

[0104] After the processing of the tap opening / closing unit 105, the cap removal unit 113 controls the operation of the cap removal mechanism 70. After the processing of the cap removal unit 113 or in conjunction with the processing of the upper movement unit 114, the upper movement unit 114 controls the operation of the upper movement mechanism 80. After the processing of the upper movement unit 114, the crimping unit 115 controls the operation of the crimping mechanism 90. After the processing of the crimping unit 115, the water supply unit 116 controls the operation of the water supply mechanism.

[0105] The control unit 120 performs control procedures for the tank water supply mechanisms 70, 80, 90 in conjunction with the control of the waste removal mechanisms 30, 40, 50.

[0106] In the above example, the operation control of the tap opening and closing mechanism 50 by the tap opening and closing unit 105 and the operation control of the cap removing mechanism 70 by the cap removing unit 113 are linked. For example, the tap opening and closing unit 105 transmits a start signal to the cap removing unit 113.

[0107] In the above example, the operation control of the cock opening / closing mechanism 50 by the cock opening / closing unit 105 is linked to the operation control of the water supply mechanism by the water supply unit 116. For example, the cock opening / closing unit 105 transmits a stop signal to the water supply unit 116.

[0108] ~Operation~ 14 is a flow chart showing the operation control by the control unit 120. The operation will be described based on the flow.

[0109] The position identifying mechanism 10 identifies the position of the discharge outlet 6 of the waste tank (step S11).

[0110] In addition, since the positional relationship between the discharge outlet 6 and the water inlet 7 remains unchanged, once the position of the discharge outlet 6 is identified, the position of the water inlet 7 is also identified. Fig. 15 is an external view of a waste tank provided in a railway vehicle. When a shutter on the side of the railway vehicle is opened, the discharge outlet 6 and the water inlet 7 are provided on the side of the waste tank so that a hose can access them. Therefore, the position of the discharge outlet 6 may be identified by identifying the position of the water inlet 7.

[0111] After the position is specified, the lower movement mechanism 20 moves in the longitudinal direction of the train so that the center of the discharge port 6 coincides with the center of the waste removal hose, and then stops (step S12).

[0112] In addition, by appropriately moving the lower movement mechanism 20, the tank water supply mechanisms 70, 80, and 90 are also positioned at appropriate positions.

[0113] After the lower moving mechanism is stopped, the upper moving mechanism 30 advances the upper mechanism including the waste removal hose toward the discharge port (step S13). As a result, the tip of the waste removal hose and the discharge port 6 come close to each other.

[0114] After the waste removal hose is placed in a predetermined position, the discharge port connection mechanism 40 connects the waste removal hose to the discharge port 6 (step S14).

[0115] After the connection is complete, the cock opening and closing mechanism 50 changes from the cock closed state to the cock open state (step S15).

[0116] This allows communication between the inside and outside of the sewage tank, and the sewage in the tank flows naturally downward via the sewage drainage hose.

[0117] Meanwhile, in conjunction with the operation of the cock opening / closing mechanism 50, the cap removing mechanism 70 also starts operating (described later).

[0118] The waste removal operation is terminated based on the appropriate time elapsed based on past experience, a remaining amount sensor (numbering omitted) installed in the tank, a flow meter (numbering omitted) installed at the discharge outlet, and other judgment indicators (step S16).

[0119] The cock opening / closing mechanism 50 changes from the cock open state to the cock closed state (step S17), thereby isolating the inside and the outside of the waste tank from each other.

[0120] Meanwhile, in conjunction with the operation of the cock opening / closing mechanism 50, the water supply mechanism also stops operating (described later).

[0121] After the cock is closed, the discharge port connection mechanism 40 releases the connection between the waste removal hose and the discharge port 6 (step S18).

[0122] After the connection is released, the upper moving mechanism 30 moves the upper mechanism including the waste removal hose back from the discharge port (step S19).

[0123] The tank water supply mechanisms 70, 80, 90 are placed in appropriate positions by the appropriate operation of the position identification mechanism 10 and the lower movement mechanism 20 (steps S11 and S12).

[0124] In conjunction with the operation of the faucet opening / closing mechanism 50 (step S15), the cap removal mechanism 70 moves to the cap of the water supply port 7 and removes the cap (step S23). For example, the cap is removed after a predetermined time has elapsed since the faucet opening operation. The cap removal mechanism 70 descends while still holding the cap, and leaves in front of the water supply port 7.

[0125] After removing the cap, upper movement mechanism 30 lowers the water supply hose so that the water supply port 7 and the water supply hose face each other, and then advances the water supply hose toward the water supply port to attach the hose to the water supply port (step S24).

[0126] After the hose is attached to the water supply port, the crimping mechanism 90 crimps the end of the hose (step S25), thereby connecting the inside and outside of the waste tank, and the water supply mechanism starts supplying water via the water supply hose.

[0127] Although the waste removal work and the water supply work coexist, the diameter of the drain outlet 6 is larger than that of the water supply outlet 7, so the amount of waste in the tank decreases even when water is supplied. The concentration of waste decreases as water is supplied, and the inside of the tank is cleaned.

[0128] The water supply operation ends (step S26) in conjunction with the operation of the cock opening / closing mechanism 50 (step S17). For example, water supply is stopped after a predetermined time has elapsed since the cock closing operation.

[0129] After the tap is closed, a certain amount of water will be supplied, but a small amount may remain in the tank.

[0130] When the water supply operation is completed, the tightening mechanism 90 loosens the tightening of the hose tip (step S27), and the upper movement mechanism 30 moves the water supply hose back from the water supply port and removes the hose from the water supply port. Furthermore, the water supply hose is raised (step S28). The hose leaves in front of the water supply port 7.

[0131] The cap removal mechanism 70 moves to the cap of the water supply port 7 and attaches the cap (step S29).

[0132] The car may wait in this state for the next waste removal, or the lower moving mechanism 20 may be released from the restraint and moved to an appropriate position in the longitudinal direction of the train.

[0133] ~Effects~ The device of the present invention can carry out a series of operations related to the work of removing waste and filling the tank with water, which have traditionally been done manually by workers. This can significantly reduce the burden on workers, and as a result, shorten the work time.

[0134] In the device of the present application, movement in the longitudinal direction of the train is limited. Meanwhile, the upper movement mechanism 30, the cock opening / closing mechanism 50, the cap removal mechanism 70, the upper movement mechanism 80, and the tightening mechanism 90 operate perpendicular to the train. In particular, the cock opening / closing mechanism 50, the cap removal mechanism 70, and the tightening mechanism 90 convert reciprocating motion into rotation. The discharge port connection mechanism 40 rotates around the hose axis. This series of movements does not interfere with each other even in a narrow range.

[0135] When waste removal and tank water supply work was done manually by workers, workability was extremely poor in a small work area due to the need to handle the waste removal hose and tank water supply hose.

[0136] According to the present device, there is no need to handle hoses, and small work areas can be effectively utilized.

[0137] When the waste removal and tank water filling tasks were performed manually by workers, the waste removal and tank water filling tasks were separate, and differences in the experience of the workers caused confusion in the work procedures.

[0138] According to the device of the present invention, the waste removal operation and the tank water supply operation can be linked together to form a continuous operation. [Explanation of symbols]
