Description

[Technical field]

[0001] The present invention relates to a vehicle with a weighing function. [Background technology]

[0002] There is known a garbage collection vehicle that can measure the weight of garbage collected at a collection site. For example, Patent Document 1 discloses a garbage collection vehicle that supports the four corners of a garbage storage box from below with load cells and measures the weight of collected garbage by adding up the weight data obtained by each load cell.

[0003] In Patent Document 1, the weight data obtained by each load cell is sent to a weighing controller installed in the cab and added up. Therefore, the wiring from the load cell to the weighing controller in the cab must be passed through a narrow space in the cab, making it difficult to route.

[0004] In addition, in Patent Document 1, the weighing controller and the handheld terminal are wirelessly connected. Patent Document 1 does not disclose a wireless antenna for wirelessly connecting the weighing controller and the handheld terminal, and there is room for improvement in the wiring between the weighing controller and the wireless antenna.

[0009] Hereinafter, one embodiment of a vehicle with a weighing function will be described with reference to Figures 1 to 5. Note that in each figure, the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match.

[0010] Fig. 1 shows a refuse collection vehicle G as an example of a vehicle with a weighing function. In Fig. 1, the front-rear direction (also called the vehicle front-rear direction) and the up-down direction of the refuse collection vehicle G are indicated by arrows, and the direction perpendicular to the paper surface is the left-right direction (also called the vehicle width direction). Fig. 2 is a rear view of the refuse collection vehicle G.

[0011] As shown in Fig. 1, the refuse collection vehicle G includes a driver's cab C, a chassis F extending rearward from the lower part of the driver's cab C, a refuse storage box B that is disposed rearward of the driver's cab C and above the chassis F and that stores refuse, and a refuse drop box T that is connected to the rear end of the refuse storage box B. The refuse collection vehicle G also includes a loading device 2 that loads the refuse that has been dropped into the refuse drop box T into the refuse storage box B. The refuse collection vehicle G also includes a discharge device 1 that discharges the refuse that has been loaded into the refuse storage box B.

[0012] The trash storage box B has a bottom wall B1 and a top wall B2 that face each other in the vertical direction, a pair of side walls B3, B3 that connect the left and right ends of the bottom wall B1 and the top wall B2, and a front wall B4 that connects the front ends of the bottom wall B1 and the top wall B2. The rear surface of the trash storage box B is inclined backward from its upper part to its lower part, and a rear end opening (not shown) is opened over the entire surface.

[0013] As shown in Fig. 1, a trash drop box T is provided adjacent to the rear opening of the trash collection box B. The trash drop box T is pivoted by a first hinge P1 provided at the upper rear part of the trash collection box B. This allows the trash drop box T to rotate vertically around the first hinge P1, and allows it to be opened and closed relative to the trash collection box B. The first hinges P1 are provided at both the left and right ends of the trash collection box B.

[0014] The trash dump box T is adapted to rotate between a closed position (solid line in FIG. 1) where the rear end opening of the trash storage box B is closed, and an open position (two-dot chain line in FIG. 1) where the rear end opening is opened to discharge trash. In FIG. 2, a pair of swing cylinders (hydraulic actuators) 30 arranged on both the left and right ends of the trash dump box T are attached at their upper ends to the trash storage box B and at their lower ends to the trash dump box T. When the swing cylinders 30 are extended, the trash dump box T is rotated upward (opened) (two-dot chain line in FIG. 1), and when the swing cylinders 30 are contracted, the trash dump box T is rotated downward (closed) (solid line in FIG. 1).

[0015] A trash inlet T1 through which trash is inserted is formed at the rear of the trash inlet T, and a lid 5 is provided to open and close the trash inlet T1 by sliding it up and down. In addition, an opening T2 for storing trash in a trash storage box B is provided at the front lower part of the trash inlet T.

[0016] The loading device 2 provided in the trash dump box T will be described with reference to FIG. 1. First, guide rails 23 extending obliquely up and down are provided on the left and right side walls T3 of the trash dump box T, and two pairs of rollers 25 attached to the slider 20 can move obliquely up and down within the guide rails 23. The slider 20 is an integrated device in which the left and right members of the side shape shown in FIG. 1 are connected to each other by a plate or the like (not shown) extending in the vehicle width direction. In addition, a push plate 21 is rotatably attached to the lower end of the slider 20 via a pin 20a. The push plate 21 is also an integrated device in which the left and right members of the side shape shown in FIG. 1 are connected to each other by a plate or the like (not shown) extending in the vehicle width direction. On the other hand, the cylinder side end of the push cylinder 22 is attached to the left and right side walls T3 by a pin 22a, and the piston side end is connected to the upper end of the slider 20 by a pin 20b. On the other hand, the cylinder side end of the press cylinder 24 is connected to the push plate 21 by a pin 24a, and the piston side end is connected to the upper end of the slider 20 by a pin 20b. The slider 20 rises obliquely together with the push plate 21 when the push cylinder 22 is extended, and falls obliquely when the push cylinder 22 is retracted. The push plate 21 also rotates clockwise around the pin 20a when the press cylinder 24 is extended, and rotates counterclockwise when the push cylinder 24 is retracted.

[0017] With the above configuration, the trash dropped into the trash drop box T is moved to the rear position by the reversal process of the pusher plate 21, compressed by the primary compression and secondary compression processes, and pushed into the trash storage box B by the pusher process. This operation constitutes one cycle, and the trash dropped into the trash drop box T is loaded into the trash storage box B. In order to operate each of the above processes sequentially, first to fourth proximity switches (not shown) are provided at appropriate positions in the trash drop box T for detecting the raised and lowered positions of the slider 20 and the rear and front positions of the pusher plate 21, respectively.

[0018] The loading operation will be described in detail. The loading operation is performed by a series of steps, including an inversion step performed by rotating the push plate 21 backward from the front position to the rear position while the slider 20 is held in the raised position by extending and retracting the push cylinder 22 and the press cylinder 24, a primary compression step performed by lowering the slider 20 from the raised position to the lower position while the push plate 21 is held in the rear position, a secondary compression step performed by rotating the push plate 21 forward from the rear position to the front position while the slider 20 is held in the lower position, and a pushing step performed by raising the slider 20 from the lower position to the raised position while the push plate 21 is held in the front position. By performing the loading operation, the input garbage in the garbage input box T is forcibly pushed into the garbage storage box B.

[0019] In this embodiment, an example of a press type that has a compression stroke in the garbage loading operation is shown, but this is not limited to this, and a rotating plate type in which garbage is loaded using a rotating plate and a pushing plate may also be used.

[0020] The discharge device 1 will be described with reference to Fig. 1. The discharge device 1 has a discharge plate 10 that can advance and retreat with respect to the trash input box T, and a storage space B5 for storing trash is formed behind the discharge plate 10 (between the discharge plate 10 and the rear end opening inside the trash storage box B).

[0021] The discharge plate 10 is composed of a discharge plate body 10a that almost fills the entire width of the internal space of the trash storage box B, and a support frame 10b that is integrally connected to the back surface of the discharge plate body 10a. A guide mechanism 11 is provided between the discharge plate 10 and the trash storage box B to guide and support the discharge plate 10 in an upright position so that it can slide forward and backward.

[0022] A single-stage or multi-stage (telescopic) hydraulic discharge cylinder 12 that drives the discharge plate 10 forward and backward is connected between the front surface of the discharge plate 10 and the front wall B4 of the trash storage box B. The discharge cylinder 12 is disposed so as to extend in the forward and backward directions substantially along the bottom wall B1 of the trash storage box B.

[0023] With the above configuration, when the storage space B5 is empty, the discharge plate 10 is in an initial position (solid line in FIG. 1) located slightly forward of the discharge position, and the garbage loaded into the garbage storage box B by the loading device 2 is compressed between the loading device 2 and the discharge plate 10. When the amount of garbage loaded increases, the discharge cylinder 12 is gradually contracted to move the discharge plate 10 forward, and the storage space B5 is expanded by moving it to the forward position shown by the two-dot chain line in FIG. 1. Also, the discharge cylinder 12 is extended to move the discharge plate 10 to a rear position protruding from the garbage storage box B, so that the garbage stored in the garbage storage box B can be discharged to the outside.

[0024] The operating device provided in the waste dump box T will be described with reference to FIG. 2. Switch boxes 61 and 62 are provided at the rear of both left and right side walls T3 of the waste dump box T. A selection switch 61a is provided on the side of the switch box 61 to select either the "continuous cycle" or "single cycle" operation mode as the operation of the loading device 2, and a loading switch 61b for starting the loading operation in each operation mode and a stop switch 61c for stopping the continuous cycle operation are provided on the front. The other switches are switches to be used only in an emergency, etc., and detailed description thereof will be omitted. The stop switch 61c is also provided in the switch box 62 on the right side.

[0025] 3 is a perspective view of the refuse collection vehicle G seen from the rear, and shows a schematic diagram of the wiring structure connecting the switch boxes 61, 62 and the control device 60. The control device 60 receives commands from the switch boxes 61, 62 and an operating device (not shown) provided in the driver's cab C to control the discharge device 1 and the loading device 2.

[0026] The control device 60 is disposed between the driver's cab C and the trash container B. The cord 60c extending from the control device 60 to the switch boxes 61 and 62 passes through the front wall B4 of the trash container B, the top wall B2 of the trash container B, the first hinge P1, the top wall T4 of the trash container T, and the side wall T3 of the trash container T in this order. Here, the cord 60c passing through the front wall B4 and the top wall B2 of the trash container B, and the top wall T4 and the side wall T3 of the trash container T includes the cord 60c not only extending along the outer surfaces of these walls, but also extending through the inside of a hollow reinforcing material for reinforcing these walls. In addition, the cord 60c passing through the first hinge P1 means passing through the space between the left and right first hinges P1 as shown in FIG. 3.

[0027] As shown in Fig. 1, the refuse collection vehicle G is provided with a plurality of load cells LC1-LC4 that are disposed between the vehicle frame F and the refuse collection box B and support the refuse collection box B from below. Note that Fig. 1 only shows the load cell LC1 and the load cell LC3. The refuse collection vehicle G also has a case 7 that is disposed behind the driver's cab C, specifically, below the refuse collection box B. The case 7 is fixed to the vehicle frame F.

[0028] FIG. 4 is a perspective view of the garbage collection vehicle G seen from the rear, and shows a schematic diagram of the wiring structure including the load cells LC1 to LC4. The load cells LC1 to LC4 are arranged at the four corners of the garbage collection box B. The load cells LC1 to LC4 include two front load cells LC1 and LC2 and two rear load cells LC3 and LC4. The load cells LC1 to LC4 can measure the weight of the garbage collection box B, the weight of the garbage input box T, and the weight of the garbage stored in the garbage collection box B. Each of the load cells LC1 to LC4 is connected to the case 7 by a wire 7a. The weight data (i.e., the load cell output value) measured by each of the load cells LC1 to LC4 (specifically, the voltage value obtained from the strain of each of the load cells LC1 to LC4) is sent to the case 7 and added up.

[0029] The waste collection vehicle G may also be equipped with an external display 8. The external display 8 is provided on the waste bin T. More specifically, the external display 8 is provided above the switch box 61 (see FIG. 2).

[0030] The external display 8 is connected to the case 7 by a communication line 7b. The communication line 7b extends from the case 7 and passes through the outer wall of the trash container B and the first hinge P1 to be connected to the external display 8. Specifically, the communication line 7b extends from the case 7 and passes through the front wall B4 of the trash container B, the top wall B2 of the trash container B, and the first hinge P1 in this order to be connected to the external display 8. Depending on the position of the case 7, the communication line 7b passes through the bottom wall B1 of the trash container B to reach the front wall B4. In addition, the communication line 7b passes through the top wall T4 of the trash container T and the left side wall T3 of the trash container T between the first hinge P1 and the external display 8.

[0031] Here, the communication line 7b passing through the front wall B4 and top wall B2 of the trash storage box B and the top wall T4 and side wall T3 of the trash drop box T includes the communication line 7b not only extending along the outer surfaces of these walls but also extending through the inside of hollow reinforcing materials for reinforcing these walls. Also, the communication line 7b passing through the first hinge P1 means that the communication line 7b passes through the space between the left and right first hinges P1 as shown in FIG.

[0032] Although the communication line 7b passes through the left side of the top wall B2 of the trash collection box B and the top wall T4 of the trash throw box T, the position of the communication line 7b in the left-right direction (vehicle width direction) is not limited to this. For example, the communication line 7b may pass through the center in the left-right direction of the top wall B2 of the trash collection box B and the top wall T4 of the trash throw box T. However, it is preferable that the communication line 7b has a wiring route similar to that of the cord 60c as much as possible.

[0033] The refuse collection vehicle G may also be equipped with a printer 9. The printer 9 is disposed in the driver's cab C. The printer 9 is connected to the case 7.

[0034] The refuse collection vehicle G also includes an accessory power supply 105. The accessory power supply 105 is disposed in the driver's cab C. The refuse collection vehicle G also includes a battery 106 that supplies electricity to the accessory power supply 105. The battery 106 is disposed below the driver's cab C.

[0035] 5 is a block diagram showing a schematic configuration of a dust weighing system. The dust weighing system 100 includes a controller 101, a calculation board 102 connected to the controller 101, and a wireless antenna 103 connected to the controller 101. The controller 101, the calculation board 102, and the wireless antenna 103 are housed in a case 7. The dust weighing system 100 also includes a remote control device 104 capable of transmitting and receiving data to and from the controller 101 via the wireless antenna 103.

[0036] The summation board 102 is connected to the load cells LC1-LC4 by wires 7a. In other words, it can be said that the controller 101 is connected to the multiple load cells LC1-LC4 via the summation board 102. The summation board 102 sums up the voltage values ​​measured by the load cells LC1-LC4. The summation board 102 converts the summed voltage value into a digital value and sends it to the controller 101.

[0037] The controller 101 has a function of acquiring the measurement value of the weight of the garbage based on the voltage value measured by the load cells LC1 to LC4. Specifically, the controller 101 converts the voltage value from the summing board 102 into weight (Kg).

[0038] The controller 101 may also have a tare function, which is, for example, a function of subtracting the weight of the trash collection box B and the trash input box T and resetting the current weight to zero.

[0039] The controller 101 may also have a data output function, and outputs data to, for example, an external display device 8 or a printer 9.

[0040] The controller 101 also has a data transmission / reception function. The controller 101 wirelessly transmits and receives data to and from a remote controller 104 via a wireless antenna 103. The wireless antenna 103 is mounted, for example, on a wireless board together with a wireless communication circuit. The wireless antenna 103 is an antenna for short-range wireless communication, for example, the antenna of a BLE module.

[0041] The controller 101, the summation board 102, and the wireless antenna 103 are housed in a case 7. At least a portion of the case 7 is made of, for example, a resin material. The case 7 is disposed outside the driver's cab C, which is a metal box, and at least a portion of the case 7 is made of a resin material, so that when the remote controller 104 is operated outside the driver's cab C, communication with the wireless antenna 103 in the case 7 is unlikely to be interrupted.

[0042] The remote control device 104 may be, for example, a smartphone, a tablet terminal, or a handheld terminal capable of wirelessly communicating with the controller 101. The remote control device 104 has operation buttons for inputting various operations. The operation buttons are not particularly limited, but may include, for example, a weighing button 104a for weighing the weight of the trash, a tare button (zero reset button) 104b for reducing the weight of the trash storage box B and the trash input box T, and an output button 104c for outputting data related to the measured value of the trash weight (hereinafter also referred to as weighing data). The operation buttons may be physical buttons or buttons displayed on a touch panel.

[0043] When the weighing button 104a is pressed by an operator, it sends a command to the controller 101 requesting a weight value obtained by weighing the weight of the trash that has been put in. When the tare button 104b is pressed by an operator, it sends a command to the controller 101 to reset the load cells LC1 to LC4 to zero. When the output button 104c is pressed by an operator, it sends a command to the controller 101 to send the weighing data of the trash to the remote controller 104.

[0044] The external display 8 includes a display unit 81 capable of displaying various information. The display unit 81 is, for example, a liquid crystal display device, and displays the measured weight of the measured garbage and the like.

[0045] The external display 8 may also include operation buttons for inputting various operations. The operation buttons are not particularly limited, but in this embodiment, three buttons are provided, for example, a tare button (zero reset button) 82 for reducing the weight of the trash storage box B and the trash input box T, a print send button 83 for outputting the trash weighing data to the printer 9, and a function button 84 for performing various settings. If the display unit 81 is a touch panel type display device, the operation buttons 82 to 84 may be buttons displayed on the touch panel of the display unit 81.

[0046] When the operator presses the tare button 82, it sends a command to the controller 101 to reset the load cells LC1 to LC4 to zero. When the operator presses the print send button 83, it sends a command to the controller 101 to send the waste weight data to the printer 9. When the operator presses the function button 84, it sends a command to the controller 101 to display on the display unit 81 a setting screen for making various settings.

[0047] The controller 101 is equipped with, for example, a CPU, and performs a predetermined operation in response to an input of an operation signal from the outside. The controller 101 resets the current weight values ​​of the load cells LC1 to LC4 to zero upon receiving a zero reset command from the tare button 104b of the remote controller 104 or the tare button 82 of the external display 8. The controller 101 also operates the load cells LC1 to LC4 to weigh the garbage upon receiving a weight value request command from the weighing button 104a of the remote controller 104, and acquires the weight value of the garbage by adding up the weight data measured by the load cells LC1 to LC4. The controller 101 also outputs the weight data to the remote controller 104 upon receiving a command to output the weight data from the output button 104c of the remote controller 104. The controller 101 also outputs the weight data to the printer 9 upon receiving a command to output the weight data from the print send button 83 of the external display 8.

[0048] The controller 101 includes a storage unit (not shown) that stores programs for executing weighing processes and weighing data.

[0049] The printer 9 is disposed in the driver's cab C. The printer 9 is connected to the controller 101, and prints out the measurement data output from the controller 101.

[0050] The controller 101 is connected to an accessory power supply 105. As a result, the controller 101 is energized and started up in conjunction with turning on the key of the vehicle.

[0051] A CAN communication terminal 107 for CAN communication may be provided in the operator's cab C. The CAN communication terminal 107 is connected to the controller 101.

[0052] Next, a brief description will be given of the collection work by the garbage collection vehicle G. First, when the garbage collection vehicle G arrives at the collection site, an operator performs a tare operation (zero reset operation) to reset the load cells LC1 to LC4 before collecting garbage. When the tare button (zero reset button) 104b, 82 is pressed by the operator, it transmits a command to the controller 101 to reset the load cells LC1 to LC4 to zero. In response to this, the controller 101 resets the current weight values ​​of the load cells LC1 to LC4 to zero.

[0053] When all the trash has been dumped into trash storage box B, the worker performs a weighing operation to start weighing the dumped trash. When the worker presses the weighing button 104a, it sends a command to the controller 101 requesting a weight value obtained by weighing the dumped trash. In response, the controller 101 operates the load cells LC1 to LC4 to weigh the trash, and adds up the weight data measured by the load cells LC1 to LC4 to obtain a weight value of the trash weight. The controller 101 also records the weighing data of the trash in the recording unit.

[0054] The worker outputs the measurement value of the weight of the garbage as necessary. When the worker presses the output button 104c, it transmits a command to the controller 101 to output the measurement data. In response to this, the controller 101 reads out the measurement data stored in the storage unit and transmits the measurement data to the remote control device 104 via the wireless antenna 103. In response to this, the remote control device 104 displays the measurement data on the screen. In other words, the remote control device 104 also functions as a display device.

[0055] The worker also prints out the measurement value of the weight of the garbage as necessary. When the worker presses the print send button 83, it sends a command to the controller 101 to output the measurement data. In response to this, the controller 101 reads out the measurement data stored in the storage unit, creates print data, and sends it to the printer 9. In response to this, the printer 9 prints the measurement data. Note that the measurement data printed by the printer 9 may include information such as customer information, collection date and time, and collected items in addition to the measurement value.

[0056] [1] From the above, it is preferable that the vehicle with weighing function (in this embodiment, a garbage collection vehicle) G, as in this embodiment, is configured to include a driver's cab C, a chassis F extending rearward in the fore-and-aft direction of the vehicle from the lower part of the driver's cab C, a storage box (in this embodiment, a garbage storage box) B arranged rearward of the driver's cab C and above the chassis F and storing an object (in this embodiment, garbage), a plurality of load cells LC1 to LC4 arranged between the chassis F and the storage box B and supporting the storage box B, a controller 101 connected to the plurality of load cells LC1 to LC4 and performing a predetermined operation upon input of an operation signal, a wireless antenna 103 connected to the controller 101 and communicating wirelessly with the outside, and a case 7 arranged rearward of the driver's cab C and storing the controller 101 and the wireless antenna 103.

[0057] According to this configuration, there is no need to run the wiring from the load cells LC1-LC4 to the controller 101 inside the cab C, making it easy to route the wiring between the load cells LC1-LC4 and the controller 101. In addition, since the controller 101 and the wireless antenna 103 are housed in the same case 7, it is easy to route the wiring between the controller 101 and the wireless antenna 103.

[0058] [2] Furthermore, in the vehicle with weighing function G (in this embodiment, a garbage collection vehicle) of [1] above, as in this embodiment, it is preferable that the controller 101 obtains a measurement value of the weight of the object (in this embodiment, garbage) based on the load cell output values ​​measured by the plurality of load cells LC1 to LC4, and that the controller 101 wirelessly transmits data related to the measurement value (in this embodiment, measurement data) to a display (in this embodiment, the remote control 104) via the wireless antenna 103 upon input of an operation signal from an operation device (in this embodiment, the remote control 104).

[0059] According to this configuration, the weight measurement value can be displayed on the remote controller 104, so that, for example, an external display for displaying the weight value is not required, and the wiring structure is simplified.

[0060] [3] Furthermore, in the vehicle with weighing function G (in this embodiment, a garbage collection vehicle) of [1] or [2] above, as in this embodiment, it is preferable to have a summation means (in this embodiment, a summation board) 102 that is connected between the plurality of load cells LC1 to LC4 and the controller 101 and sums up the load cell output values ​​measured by each of the load cells LC1 to LC4, and the summation means 102 is housed in the case 7, as in this embodiment.

[0061] According to this configuration, since the controller 101 and the summing means 102 are housed in the same case 7, it is easy to arrange the wiring between them.

[0062] [4] Furthermore, in any one of the vehicles with weighing function (in this embodiment, a garbage collection vehicle) G described above in [1] to [3], it is preferable that the case 7 is arranged below the storage box (in this embodiment, a garbage storage box) B and fixed to the chassis F, as in this embodiment.

[0063] According to this configuration, the case 7 is disposed below the storage box, so that it can be protected from rain. Also, the wiring from the battery 106 to the case 7 can be shortened.

[0064] [5] In addition, in any one of the above-mentioned vehicles with weighing function [1] to [4] (in this embodiment, a garbage collection vehicle) G, it is preferable that at least a portion of the case 7 is formed from a resin material, as in this embodiment.

[0065] According to this configuration, when the remote controller 104 is operated outside the cab C, communication with the wireless antenna 103 inside the case 7 is unlikely to be interrupted.

[0066] Although the embodiments of the present invention have been described above based on the drawings, the specific configuration should not be considered to be limited to these embodiments. The scope of the present invention is indicated not only by the description of the above embodiments but also by the claims, and further includes all modifications within the meaning and scope of the claims.

[0067] The structures employed in the above-described embodiments can be employed in any other embodiment. The specific configurations of each part are not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention. Furthermore, one or more of the configurations, methods, etc. relating to the various modified examples described below may be arbitrarily selected and employed in the configurations, methods, etc. relating to the above-described embodiments.

[0068] (A) In the garbage collection vehicle G according to the above embodiment, the controller 101 acquires a measurement value of the garbage weight based on the load cell output value measured by the multiple load cells LC1 to LC4, and the controller 101 wirelessly transmits the measurement data to the remote control device 104 via the wireless antenna 103 in response to an input of an operation signal from the remote control device 104. However, the garbage collection vehicle G is not limited to such a configuration. For example, the operation device may be an operation device (e.g., a wired remote control) connected to the controller 101 by a wire. In this case, the controller 101 may be configured to wirelessly transmit the measurement data to the remote control device 104 via the wireless antenna 103 in response to an input of an operation signal from the wired remote control. In other words, the controller 101 may be configured to wirelessly transmit the measurement data to the display device via the wireless antenna 103 in response to an input of a wired or wireless operation signal from the operation device.

[0069] Also, the controller 101 may be configured to obtain a measurement value of the weight of the garbage based on the load cell output values ​​measured by the multiple load cells LC1 to LC4, and to transmit data related to the measurement value to a display (e.g., external display 8) in response to an input of an operation signal from a remote controller 104 via a wireless antenna 103. In other words, the controller 101 may be configured to transmit data related to the measurement value to the display by wire in response to an input of an operation signal from the controller via the wireless antenna 103.

[0070] (B) The garbage collection vehicle G according to the above embodiment is configured to include a summing board 102 that is connected between a plurality of load cells LC1 to LC4 and a controller 101 and sums up load cell output values ​​measured by the load cells LC1 to LC4, and the summing board 102 is housed in a case 7. However, the garbage collection vehicle G is not limited to such a configuration. For example, the summing board 102 may be housed in a case separate from the case 7.

[0071] Alternatively, the load cells LC1 to LC4 may be digital load cells, and a CPU may be provided within the digital load cells to sum up the load cell output values ​​measured by the load cells LC1 to LC4 using this CPU (i.e., an example of a summing means).The controller 101 may also function as the summing board 102.

[0072] Furthermore, the garbage collection vehicle G may be provided with a terminal block box (i.e., an example of a summing means) that is connected between the plurality of load cells LC1 to LC4 and the controller 101 and sums up the load cell output values ​​measured by each of the load cells LC1 to LC4, and the terminal block box may be housed in the case 7. The terminal block box is connected to the load cells LC1 to LC4 by electrical wiring, and is also connected to the controller 101 by electrical wiring. Then, in the terminal block box, the voltage values ​​from the load cells LC1 to LC4 are summed up, and the summed voltage value is output to the controller 101.

[0073] (C) In the garbage collection vehicle G according to the above embodiment, the case 7 is arranged below the garbage storage box B and fixed to the vehicle frame F. However, the garbage collection vehicle G is not limited to such a configuration. The case 7 may be arranged behind the driver's cab C, and may be fixed to the garbage storage box B or the garbage insertion box T, for example. However, since the garbage insertion box T rotates in the vertical direction, if the case 7 is fixed to the garbage insertion box T side, the wiring from the battery 106 must be passed through the first hinge P1, and the wiring becomes long. Therefore, it is preferable that the case 7 is fixed to the garbage storage box B side. Also, when the discharge device 1 of the garbage storage box B is a dump type, the garbage storage box B rotates around the rear hinge, so that the case 7 is preferably fixed to the vehicle frame F.

[0074] (D) In ​​the refuse collection vehicle G according to the above embodiment, the case 7 is configured to be made of a resin material. However, the refuse collection vehicle G is not limited to this configuration. The case 7 may be configured to be made of a metal material. In this case, it is preferable to provide a hole near the wireless antenna 103 so as to facilitate communication with the wireless antenna 103 housed therein. Furthermore, the hole may be covered with a material that does not easily impede communication. In other words, the case may be provided with a material that does not easily impede communication in at least a portion thereof.

[0075] (E) Although the refuse collection vehicle G according to the above embodiment is configured to include the external display device 8, the external display device 8 may be omitted.

[0076] (F) In the sewage collection vehicle G according to the above embodiment, the controller 101 is connected to the accessory power supply 105, but it may also be connected directly to the battery 106.

[0077] (G) In the garbage collection vehicle G according to the above embodiment, the printer 9 is connected to the controller 101 by wire. However, the garbage collection vehicle G is not limited to this configuration. The printer 9 does not have to be provided on the garbage collection vehicle G, but may be carried by the operator. In this case, the printer 9 communicates wirelessly with the controller 101. The printer 9 may also be housed in the case 7.

[0078] (H) In the waste collection vehicle G according to the above embodiment, the discharge device 1 is a so-called discharge plate type that includes a discharge plate 10 that can move in the fore-and-aft direction of the vehicle inside the waste storage box B. However, the waste collection vehicle G is not limited to this configuration. The discharge device 1 may be a so-called dump type.

[0079] (I) In the above embodiment, a garbage collection vehicle G is shown as an example of a vehicle with a weighing function, but a vehicle with a weighing function may be any vehicle equipped with a weighing function, such as a dump truck, a container transporter, or a vehicle equipped with a tank.
