Description

[Technical field]

[0001] The present invention relates to a vehicle that can indicate if there is a bias in the weight of contents contained in a cargo box. [Background technology]

[0002] A vehicle capable of storing items in a cargo box mounted on the vehicle body is disclosed in, for example, Patent Document 1. If the weight of the items in the cargo box is concentrated in a specific location, the weight of the entire vehicle carrying the cargo box will be unbalanced, and if the vehicle is driven in this state, it will lose balance and be dangerous. Therefore, the invention disclosed in Patent Document 1 discloses a configuration that can detect the weight of the items in the cargo box being concentrated in a specific location. When the invention disclosed in Patent Document 1 indicates that the weight of the items (the cargo box) is unbalanced, the position of the items can be changed to equalize the weight bias of the items. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 61-076919 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional vehicle disclosed in Patent Document 1, a warning device that warns of uneven weight distribution of the cargo boxes is provided in the driver's seat of the vehicle. However, since the worker who places the contents in the cargo boxes is in the vicinity of the cargo boxes away from the driver's seat, it is difficult for the worker to recognize the warning from the warning device in the driver's seat.

[0005] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a vehicle that enables a worker who places items in a cargo box to easily recognize if there is a bias in the weight of the items in the cargo box. [Means for solving the problem]

[0006] A first aspect of the present invention for solving the above problem is a vehicle having a storage area for storing items mounted on the vehicle body, the vehicle having a plurality of weight detection devices for detecting the weight of the items stored in the storage area, a control device, and an alarm device, each of the weight detection devices being arranged at a predetermined interval between the vehicle body and the storage area, the control device having a function of comparing weight information detected by each of the weight detection devices, and the control device being capable of issuing an alarm command signal to the alarm device if there is a difference of a predetermined amount or more in the compared weight information, the vehicle being characterized in that the alarm device is provided in the storage area.

[0007] According to this aspect, since the alarm device is provided in the storage area, the alarm device can notify the vicinity of the storage area that there is a predetermined or greater imbalance in the weights of the items stored in the storage area. Therefore, a worker who stores items in the storage area can recognize the alarm from the alarm device. That is, the worker can recognize that the items are not loaded into the storage area so that they are of equal weight. As a result, the worker can realize that the positions of the items must be corrected so that the weights of the items stored in the storage area are uniform, and can be prompted to correct the positions of the items. Therefore, before the vehicle is driven, it is possible to obtain an opportunity to move the contents within the storage area and eliminate (reduce) the imbalance in the weight of the contents within the storage area. This also makes it possible to avoid a situation in which the vehicle is driven in a state where the weight of the items stored in the storage area is unbalanced to a certain extent, thereby ensuring safety. Here, an alarm device refers to a device that vibrates, sounds, lights up, or flashes based on an alarm command signal from a control device, or a device that can operate a specific component (for example, a rotating body rotates) or change its state (for example, a display color changes).

[0008] It is preferable that the vehicle is a garbage collection vehicle, the loading box has a garbage storage box, a garbage throw-in box and a loading device, the garbage storage box and the garbage throw-in box are connected, the garbage throw-in box is provided with a loading device, and garbage, which is the contents thrown into the garbage throw-in box, is pushed into the garbage storage box by the loading device.

[0009] The loading device pushes the trash into the trash storage box of the packing box. That is, regardless of the weight of each piece of trash, the trash is pushed into the trash storage box at the back in the order it was put in and stored there. Therefore, even if there is an imbalance in the weight of the trash storage box (dust), the worker cannot know. However, with this configuration, the worker can easily know that the weight of the trash storage box is uneven. Effect of the Invention

[0010] In the vehicle of the present invention, the worker who stores items in the storage area of ​​the vehicle can easily recognize the uneven distribution of weights of the items in the storage area, and therefore it is possible to prevent the vehicle from traveling with the weights of the items in the storage area being uneven, thereby ensuring safety.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The following description will be given with reference to the drawings. As shown in Fig. 1, a vehicle 1 has a vehicle body 2 (chassis frame) having a driver's seat 2a, and a cargo box 3 (storage area) mounted on the vehicle body 2. An opening 7 for inserting and removing stored items is provided on the rear side of the cargo box 3. An opening 7 is provided with an opening door 3a. The opening door 3a is a double-door.

[0013] Notification devices 6a to 6d are provided at the front and rear positions on the outer surface on both sides of the packing box 3. The notification devices 6a to 6d are provided on the packing box 3, so that they can notify the surroundings of the packing box 3.

[0014] The notification devices 6a to 6d are light-up or flashing indicator lights (LED lamps) and are activated by a notification command signal described below. The notification devices 6a to 6d may employ speakers instead of indicator lights and emit warning sounds (i.e., ring). The notification devices 6a to 6d may also emit light and sound simultaneously.

[0015] A plurality of weight detection devices 4a to 4d are provided between the vehicle body 2 and the cargo box 3. That is, each of the weight detection devices 4a to 4d is sandwiched vertically by the vehicle body 2 and the cargo box 3. As shown in FIG. 2, the weight detection devices 4a to 4d are disposed at the four corners of the cargo box 3. That is, each of the weight detection devices 4a to 4d is disposed at a predetermined interval from each other. The weight detection devices 4a to 4d are load cells. The weight detection devices 4a to 4d on the vehicle body 2 support a part or all of the weight of the cargo box 3.

[0016] The driver's seat 2a is provided with a control device 5. The control device 5 has various functions, and can receive signals of weight information detected by the weight detection devices 4a to 4d and transmit notification command signals to the notification devices 6a (6b, 6c, 6d) by wire (not shown) or wirelessly.

[0017] FIG. 3(a) shows the positional relationship between a baggage P loaded inside a cargo box 3 of a vehicle 1, weight detection devices 4a, 4c, 4d, and notification devices 6a, 6c, 6d.

[0018] A worker loads luggage P (in this embodiment, a cardboard box filled with luggage) into a packing box 3 indicated by a two-dot chain line, and in FIG. 3(a), a large number of luggage P (cardboard boxes) are stacked vertically and horizontally at the same height. Two rows of luggage P are arranged with a gap D between them. The gap D is provided to ensure space for a worker to enter. The worker enters the packing box 3 from the gap D and loads the luggage P into the packing box 3.

[0019] However, the weight of each piece of luggage P is not uniform, and there is a mixture of heavy and light luggage. Therefore, the weight inside the luggage box 3 changes depending on how the luggage P is stacked. The weight of the luggage box 3 containing each piece of luggage P can be found by using weight detection devices 4a to 4d arranged at the four corners of the lower part of the luggage box 3 and a control device 5 provided in the driver's seat 2a.

[0020] That is, each of the weight detection devices 4a-4d transmits the detected weight information to the control device 5. The control device 5 calculates the weight bias of the cargo box 3 from the weight information received from each of the weight detection devices 4a-4d. That is, it calculates the weight difference in the left-right direction and the weight difference in the front-rear direction of the vehicle 1. Then, when the left-right and / or front-rear weight bias (difference) is equal to or exceeds a preset value, the control device 5 transmits an alarm command signal to the alarm device 6. The alarm device 6a (6b, 6c, 6d) (indicator lamp) that receives the alarm command signal performs lighting or blinking (alarm operation).

[0021] In this embodiment, on the premise that there is a predetermined difference or more between the weight values ​​detected by the left and right weight detection devices 4a, 4b on the front side of the vehicle 1, the notification device near the weight detection device that detected the heavy weight value lights up in red, and the notification device near the weight detection device that detected the light weight value flashes in red. Similarly, on the premise that there is a predetermined difference or more between the weight values ​​detected by the left and right weight detection devices 4c, 4d on the rear side of the vehicle 1, the notification device near the weight detection device that detected the heavy weight value lights up in blue, and the notification device near the weight detection device that detected the light weight value flashes in blue.

[0022] In the example shown in Fig. 3(a), the weight values ​​detected by the weight detection devices 4a, 4d, 4c, and 4b are larger in this order. That is, at the front of the vehicle 1, the weight value detected by the weight detection device 4a is larger than the weight value detected by the weight detection device 4b by a predetermined amount, and at the rear of the vehicle 1, the weight value detected by the weight detection device 4d is larger than the weight value detected by the weight detection device 4c by a predetermined amount. In other words, at the front of the vehicle 1, the left side is heavier than the right side by a predetermined amount, and at the rear, the right side is heavier than the left side by a predetermined amount. Therefore, weight bias occurs in the cargo box 3. At this time, the notification device 6a lights up in red, the notification device 6b flashes in red, the notification device 6c flashes in blue, and the notification device 6d lights up in blue.

[0023] Therefore, the worker moves (piles up) some of the luggage P near weight detection device 4a (front left side of vehicle 1) that detected a heavy weight value to near weight detection device 4b (front right side of vehicle 1) that detected a light weight value. Also, the worker moves some of the luggage P near weight detection device 4d (rear right side of vehicle 1) that detected a heavy weight value to near weight detection device 4c (rear left side of vehicle 1) that detected a light weight value.

[0024] As a result, when the notification devices 6a to 6d stop notifying, the weight imbalance of the vehicle 1 is below a predetermined level. That is, there is no weight difference between the left and right sides at the front and rear of the vehicle 1, and the imbalance is eliminated.

[0025] When equalizing the weight of the vehicle 1 (packing box 3), it is necessary to make the weight difference between the left and right and the front and rear of the vehicle 1 within a predetermined value. For this reason, the luggage P is moved not only between the left and right sides of the vehicle 1, but also between the front and rear of the vehicle 1 in some cases. The luggage P is moved so that the weight variation is eliminated for the entire vehicle 1.

[0026] As in this embodiment, by each of the notification devices 6a to 6d lighting up or flashing, the worker can recognize that weight imbalance has occurred in the packing boxes 3. The worker can then realize that he or she must correct the positions of the luggage P so that the weights of the packing boxes 3 are uniform, and can be prompted to correct the positions of the luggage P. If the order of heaviest (or lightest) weights can be determined from the notification method of the notification devices 6a to 6d, the weight imbalance can be easily eliminated by moving the heaviest luggage P to the lightest position.

[0027] The alarm devices 6a and 6c stop the alarm operation when there is no more imbalance in the weight of the packing box 3 (luggage P). The worker continues to move the luggage P by trial and error until the alarm devices 6a-6b stop alarming. In other words, when all of the alarm devices 6a-6d stop alarming, the weight imbalance in the entire area of ​​the packing box 3 is within a predetermined range.

[0028] Here, the predetermined range means that the ratio of the heaviest weight to the lightest weight is within 1.5 times, and more preferably within 1.2 times.

[0029] In the vehicle 1 according to this embodiment, the notification devices 6a to 6d are provided near the four corners of the cargo box 3, so that when any of the notification devices 6a (6b, 6c, 6d) performs a notification operation, workers around the cargo box 3 can easily recognize that there is a bias in the weight of the cargo box 3. This provides an opportunity to change the position (layout) of the packages P in the cargo box 3 and eliminate the bias in weight.

[0030] The alarm devices 6a to 6d, which are indicator lights, can be made to flash or light and sound at the same time, so that even if an operator is on the side of the vehicle 1, he or she can easily recognize the alarm operation of the alarm device arranged on the opposite side.

[0031] As described above, the weight detection devices 4a-4d, the control device 5, and the notification devices 6a-6d constitute a bias measurement means for measuring the bias of the weight of the cargo box 3 (vehicle 1). The bias measurement means can estimate the weight difference between the front, rear, left and right sides of the vehicle 1 from the amount of suspension deflection and the difference in air pressure in each tire. Alternatively, the weight difference between the front, rear, left and right sides of the vehicle 1 can be estimated by detecting the inclination of the vehicle 1 with an inclination sensor.

[0032] In this embodiment, an example in which all the notification devices 6a to 6d give notification has been shown, but instead, it is also possible to have only the notification device 6a (6b to 6d) in the heaviest area give notification. Furthermore, it is also possible to make it possible to grasp the weight of the front, back, left and right of the packing box 3 by using different light emission colors.

[0033] Further, as described above, the notification device may be provided in the storage area (packing box 3) and next to the driver's seat 2a.

[0034] In this embodiment, an example has been shown in which the notification devices 6a to 6d are arranged on the outside of the packing box 3, but these notification devices 6a to 6d may also be arranged on the inside of the packing box 3. In particular, if the notification devices 6c and 6d are installed near the ceiling wall near the opening 7, a worker can immediately recognize that a weight imbalance has occurred when loading the luggage P into the packing box 3.

[0035] Next, another vehicle 11 (hereinafter referred to as a refuse collection vehicle 11) will be described with reference to Figs.

[0036] As shown in Figures 4(a) and 4(b), the refuse collection vehicle 11 is equipped with a vehicle body 12 having a driver's seat 12a, and a packing box 13. The packing box 13 is provided on the vehicle body 12. The packing box 13 is equipped with a refuse storage box 14 and a refuse throwing box 15, in that order from the front side of the refuse collection vehicle 11. The refuse throwing box 15 is connected (continuous) to the refuse storage box 14, and is provided with a loading device 16 shown by a dashed line inside. The refuse throwing box 15 is provided with an insertion opening 15a at the rear side for throwing in refuse. The insertion opening 15a is provided with an opening / closing door 17 shown in Figures 5(a) to 5(c).

[0037] Weight detection devices 24a to 24d similar to those of the vehicle 1 shown in Fig. 2 are provided at the four corners between the vehicle body 12 and the cargo box 13. That is, the weight detection devices 24a to 24d are load cells similar to the weight detection devices 4a to 4d.

[0038] Notification devices 26a to 26d are provided near the four corners of the lower outside of the packing box 13. The notification devices 26a to 26d are indicator lights similar to the notification devices 6a to 6d in Fig. 2. Also, as shown in Figs. 5(b) and 5(c), inside notification devices 27a and 27b are provided inside the trash bin 15 at positions near both sides of the opening and closing door 17. The inside notification devices 27a and 27b are also indicator lights similar to the notification devices 6a to 6d in Fig. 2. The inside notification devices 27a and 27b are located at positions where they can be seen by an operator from outside the packing box 13 (the trash bin 15) and do not interfere with the opening and closing of the opening and closing door 17.

[0039] Furthermore, the driver's seat 12a is provided with a control device 25. The control device 25 is capable of transmitting and receiving signals to and from the weight detection devices 24a to 24d and the notification devices 26a to 26d via wires (not shown) or wirelessly.

[0040] When a worker inserts trash from the insertion port 15a, the inserted trash is pushed forward by the loading device 16 and moves from the trash insertion box 15 to the trash storage box 14. The trash moves forward in the order that it was inserted from the insertion port 15a, and is stored in the trash storage box 14.

[0041] That is, since the inside of the trash storage box 14 cannot be seen, the worker cannot grasp how the trash that has been put in will be stored in the trash storage box 14. Conversely, the worker cannot store the trash in the trash storage box 14 without weight imbalance. Therefore, there is a concern that a large amount of trash will be stored in the trash storage box 14, resulting in a situation in which the weight of the packing box 13 will be unbalanced to the left and right or front and back.

[0042] However, in the refuse collection vehicle 11 according to this embodiment, weight information detected by each weight detection device 24a-24d is transmitted to the control device 25, which calculates the weight information and, if there is a weight difference of a predetermined value or more, transmits an alarm command signal to the alarm device 26a (26b, 26c, 26d) near the weight detection device 24a (24b, 24c, 24d) that detected the largest weight. Then, the alarm device 26a (26b, 26c, 26d) and the internal alarm device 27a (27b) that receive the alarm command signal perform an alarm operation.

[0043] Since the notification devices 26a-26d are provided on the outside of the packing box 13, a worker near the packing box 13 can easily recognize the notification operation of the notification devices 26a-26d. Then, the worker can take measures to eliminate the imbalance in the weight of the garbage in the packing box 13, or to make sure that the imbalance (difference) in weight is equal to or less than a predetermined value.

[0044] Furthermore, the worker can recognize the alarm action of the inside alarm devices 27a, 27b when he or she is putting garbage into the garbage dump box 15. Therefore, the worker can immediately take measures to make sure that the weight imbalance of the garbage is within a predetermined level. Incidentally, the inside alarm devices 27a, 27b are disposed inside the packing box 13 (garbage dump box 15) rather than the opening and closing door 17. Therefore, when the opening and closing door 17 is closed, such as when the garbage collection vehicle 11 is traveling, the inside alarm devices 27a, 27b cannot be seen from the outside.

[0045] In the above, an example was shown in which the vehicle 1, the refuse collection vehicle 11, is provided with the cargo boxes 3, 13, but the present invention can be similarly implemented in a vehicle (such as a dump truck) that has a cargo box with an open roof. Even if a part (the back side) of the cargo box is hidden by the load, the weight imbalance can be eliminated by the alarm device, or the weight imbalance (difference) can be arranged to be within a predetermined level.
