Description

  The present invention relates to a weighing device. In particular, the present invention relates to an improvement in the weighing technique of the input to the container.

  2. Description of the Related Art A cargo handling vehicle capable of loading and unloading containers between the ground and a chassis is already known (see, for example, Patent Documents 1 and 2). When a container is removed from such a cargo handling vehicle and temporarily placed on the ground, an input supplier can always input the input to the container, such as waste and resource recovery, into the container.

  In addition, a container collection organization (such as an environmental management department of a municipality) can collect a container into which an input material has been loaded using a cargo handling vehicle in a timely manner.

  In this case, there is a container collection system in which a load cell is arranged at the bottom of the container so that the amount of input loaded in the container can be detected (see, for example, Patent Documents 3 and 4 as conventional examples).

JP 2008-296622 A JP 2008-296623 A JP 2003-104505 A JP 2003-63603 A

  However, even using the above-mentioned conventional example, it is only possible to weigh the total weight of the input material loaded in the container, and it is possible to determine who, what, when, what, and how much, I can't know. For this reason, when multiple input companies input various types of inputs into the container, in the conventional example, it is possible to specify the type of input, specify the input company, It cannot be specified and is very user-friendly. For example, a container collection organization cannot even charge an input contractor for processing costs of input.

  Japanese Patent Application Laid-Open No. 2003-63659 describes that an IC tag is used for a container freight input slip in which logistics information such as the type, weight, destination, and shipper of a container in a container terminal is entered. However, this publication does not intend to update the information of the IC tag between the container sealing and the container opening. Therefore, the technique described in Japanese Patent Application Laid-Open No. 2003-63659 is not useful in solving the above inconvenience.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a weighing device that can acquire an input history of an input every time an input is input into a container.

In order to solve the above problems, the present invention provides a container capable of charging an input,
A load cell fixed to the bottom of the container;
Input means used to input the input history of the input;
A controller to which the load cell is connected,
The controller calculates an input amount of the input charge based on an output of the load cell every time the input is input to the container, and inputs the input using the input means. Provided is a weighing device that acquires a history.

  In the weighing device of the present invention, the input means includes a first input means used for acquiring personal information of the input trader, a second input means used for acquiring the type of the input, and the input And a third input unit used for obtaining the input date and time.

  As a result, it is possible to know afterwards who has put “who”, “when”, “what”, and “how much” into the container. Therefore, in the weighing apparatus according to the present invention, even when a plurality of input companies input various types of input into the container, the input date and time of the input, the input type, the input supplier and the input amount of the input Can be identified appropriately. As a result, the weighing device is much more convenient than the conventional example. For example, the container collection organization can charge the input processing cost to the input supplier.

  In the weighing device of the present invention, the first input means may be an RFID (Radio Frequency Identification) reader. The third input means may be a real time clock.

  Further, the weighing device of the present invention may be provided with a slot that is connected to the controller and in which a memory card storing the insertion history and the insertion amount can be mounted.

  As a result, the memory card storing the input history and the input amount can be removed from the weighing device in a timely manner. As a result, such data can be used for various purposes.

  In the weighing device of the present invention, the container may be divided into a plurality of areas, and each of the areas may have a predetermined type of input to be input. Each of the output terminals of the plurality of load cells may be connected to the controller, and each of the plurality of load cells may be arranged corresponding to each of the plurality of regions.

  Thereby, it is considered that the controller can predict the room in which the input material is actually input by the operator based on the output data of each of the plurality of load cells. Therefore, if the type corresponding to the room where the input is actually performed (the room based on the prediction of the controller) is different from the type of the input selected by the operator, the controller Can give a warning.

  According to the present invention, it is possible to obtain a weighing device that can acquire the input history of the input every time the input is input into the container.

That is, the following specific description merely illustrates the features of the weighing device of the present invention. Therefore, when the following specific examples are described with appropriate reference numerals attached to the terms corresponding to the components that specify the weighing device of the present invention, the specific device corresponds to the inclination angle of the present invention corresponding thereto. It is an example of the component of an arithmetic unit. For example, “CPU 23” described below is merely an example of “controller” which is a component of the present invention.

(Embodiment)
FIG. 1 is a diagram illustrating a configuration example of a weighing device according to an embodiment of the present invention. 1A shows a side view of the weighing device 100, and FIG. 1B shows a view of the weighing device 100 of FIG.

  In an appropriate drawing, the direction in which the weighing device 100 is subjected to its own weight is indicated by “up and down”, the longitudinal direction of the weighing device 100 is indicated by “front and rear”, and the direction perpendicular to these two directions is indicated by “left and right”. It is shown.

  As shown in FIG. 1, the weighing device 100 includes a rectangular container 10 into which inputs such as waste and resource recovery can be input, and four load cells LC fixed to a base 11 (bottom) of the container 10. And an indicator 20 described in detail below.

  The container 10 includes a hook (not shown) arranged on a reinforcing girder (not shown) at the front end of the container 10 and a pair of traveling wheels 13 arranged on the left and right near the rear end of the base 11. It is configured to be able to be loaded and unloaded between the ground 200 and a chassis (not shown) of a cargo handling vehicle (not shown). FIG. 1 shows a state in which the container 10 is placed on the ground 200 via the load cell LC. Thus, the container 10 is a detachable container that can be detached from the cargo handling vehicle.

  However, the loading and unloading structure of the container 10 is known (see Patent Documents 1 and 2). Therefore, detailed description of this structure is omitted.

  Further, in the weighing device 100 of the present embodiment, the four load cells LC placed on the ground 200 are distributed and arranged in the front-rear direction and the left-right direction of the container 10, whereby the load cell LC is inserted into the container 10. The total weight of the container 10 including the input amount (weight) of the object can be detected.

  Next, a configuration example of the indicator 20 of the weighing device 100 that is a characteristic part of the present embodiment will be described.

  FIG. 2 is a block diagram showing an example of the indicator of FIG.

  Here, as shown in FIG. 1, the indicator 20 is fixed at an appropriate position at the rear end of the container 10. However, the indicator 20 is provided at another location as long as it does not hinder the loading and unloading work of the container 10. May be.

  The indicator 20 includes a CPU (Central Processing Unit; controller) 23 composed of a macro processor or the like, and various components described below are connected to the CPU 23 inside the indicator 20.

  First, as shown in FIG. 2, the CPU 23 is electrically connected to each of the four load cells LC described above via four A / D (analog / digital) converters 21.

  Thereby, after the analog signal output from each of the load cells LC is converted into a digital signal, these digitized signals enter the CPU 23. The magnitude of the signal digitized by the A / D converter 21 is proportional to the weight of the container 10. Therefore, the CPU 23 can sequentially acquire the weight of the entire container 10 based on these digital signals.

  Further, as shown in FIG. 2, the CPU 23 is connected to an input unit used for inputting an input history of input into the container 10 (details will be described later). As such input means, here, there are a key input unit 25, an RFID (Radio Frequency Identification) reader 26, and a real-time clock 28.

  The key input unit 25 includes, for example, a plurality of switches arranged corresponding to the type of input (an example of input input history). When an appropriate switch of the key input unit 25 is pressed (selected) by the input trader, the CPU 23 can acquire the type of input corresponding to the selected switch.

The RFID reader 26 is a short-distance wireless communication using an electromagnetic field, a radio wave, etc. from an RFID card (not shown) in which personal information (an example of the input history of the input) of the supplier is embedded and IC-tagged. It is an electronic device that can read personal information. Further, the RFID reader 26 can instantly transmit the personal information to the CPU 23 upon reading this personal information.
Examples of the personal information of the input supplier include “input supplier ID” and “input supplier name”.

  The real-time clock 28 is a timekeeping chip mounted on the substrate, and the CPU 23 can acquire the input date and time of the input from the real-time clock 28. For example, the CPU 23 may acquire the date and time of the real-time clock 28 when the input trader operates the key input unit 25. If the date / time of the real-time clock 28 is not set appropriately, the date / time of the real-time clock 28 is adjusted by a command from the CPU 23.

  As shown in FIG. 2, the CPU 23 is connected to the internal memory 27 and the USB / CF slot 22. As a result, the CPU 23 can exchange data between the internal memory 27 and a memory card (not shown) mounted in the USB / CF slot 22.

  The internal memory 27 is composed of, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory), and stores a program for executing the operation of the weighing device 100. The internal memory 27 can also temporarily store “input input history and input amount list” (described later).

  In the USB / CF slot 22, a memory card (not shown) such as a USB flash memory or a CF card can be mounted, whereby the memory card storing the list can be taken out from the measuring device 100 in a timely manner. As a result, such a list can be used for various purposes.

  Further, as shown in FIG. 2, the CPU 23 is connected to the notification device 24. The reporting device 24 includes, for example, a liquid crystal display panel and a speaker. As a result, various messages output from the CPU 23 can be notified to the operator of the supplier by display or voice.

  As shown in FIG. 2, the power supply system of the indicator 20 includes a solar panel 30, a charging circuit 31, and a secondary battery 32. The container 10 of the weighing device 100 is always installed on the outdoor ground 200 except when the container 10 is collected. Therefore, it is convenient to cover the power supply of the indicator 20 of the container 10 with the solar panel 30.

  Next, an example of an input process flow of the input by the weighing device 100 according to the embodiment of the present invention will be described with reference to the drawings.

  FIG. 3 is a flowchart showing an example of an input process flow of the input by the weighing device according to the embodiment of the present invention.

When the operator presses an input work start button (not shown) (step S1), the CPU 23 reads a program for input process from the internal memory 27.
Thereby, CPU23 can start the following injection | throwing-in operations using the weighing device 100. Note that an instruction that an operator needs to perform to execute this operation as follows is displayed as a message on the display screen of the reporting device 24.

First, the worker holds the RFID card he / she brought to the RFID reader 26 when starting the loading operation (step S2). Then, the CPU 23 reads the personal information (input company ID and input company name) of the input company stored in the RFID card (step S3).
If the CPU 23 succeeds in reading the personal information of the supplier (in the case of “Yes” in step S4), the CPU 23 proceeds to the next step.

  As described above, it is possible to leave a history of “who” has put the input into the container 10, and the convenience of the weighing device 100 is improved.

  On the other hand, if the CPU 23 has not successfully read the personal information of the supplier (in the case of “No” in step S4), the CPU 23 displays an error message on the display screen of the reporting device 24 (step S15), and this operation Exit.

  Next, on the display screen of the reporting device 24, a message for inquiring about the type of the input to be input into the container 10 is displayed, and the operator selects the type of the input using the key input unit 25 in accordance with this message. (Step S5). Then, CPU23 can acquire the kind of input material (step S6). At the same time, the CPU 23 obtains the input date and time (year / month / day and time) using the real-time clock 28 (step S6).

  As described above, it is possible to leave a history of “what” and “when” in the container 10, and the convenience of the weighing device 100 is improved.

  Next, the CPU 23 obtains (calculates) the total weight of the container 10 before charging the input based on the output data of the load cell LC, and then the CPU 23 stores this weight in the internal memory 27 (step S7).

Thereafter, when an input possible lamp (not shown) is turned on (step S8), the operator can input the input into the container 10 (step S9).
When the input of the input into the container 10 is completed, the worker presses an input completion button (not shown) (step S10).

  Then, the input possible lamp is turned off (step S11), and the CPU 23 waits for the output data of the load cell LC to be stabilized (step S12). When the output data is stabilized, the CPU 23 obtains (calculates) the weight of the entire container 10 after the input material is input based on the output data, and then the CPU 23 stores the weight in the internal memory 27 (step S12).

  Next, the CPU 23 reads the weight of the entire container 10 before the input of the input in step S7 and the weight of the entire container 10 after the input of the input in step S12 from the internal memory, and from the latter weight to the former weight. Is obtained (calculated) (step S13).

  As described above, it is possible to leave a history of “how much” the input material has been input to the container 10, and the convenience of the weighing device 100 is improved.

  Next, the personal information (input supplier ID and input supplier name) of the input supplier, the type of the input, the input date and time (date and time), and the input amount of the input are respectively stored in the internal memory 27 and the USB. The data is stored in the memory card mounted in the / CF slot 22 (step S14). In this case, it is convenient to collect the above data as “a list of input history and amount of input” as shown in Table 1 below.

  Thereafter, a message for inquiring whether or not the operation of loading the input material into the container 10 may be terminated is displayed on the display screen of the reporting device 24 (step S16), and the worker continues the loading operation ( In the case of “No” in step S16; for example, when an input of another type is input, an input input operation continuation button (not shown) is pressed. Then, the process flow returns to step S5, and the operations after step S5 are performed again.

  On the other hand, when the worker does not continue the loading operation (in the case of “Yes” in step S16), the worker presses an input loading operation end button (not shown) (step S17), and the weighing device 100 A series of input operations using is completed.

  As described above, the weighing device 100 of the present embodiment includes the container 10 into which the input can be input, the load cell LC fixed to the base 11 of the container 10, and various input means 25 used for inputting the input history of the input, 26 and 28, and an indicator 20 having a CPU 23 (controller) to which a load cell LC is connected.

  The CPU 23 calculates the input amount of the input material into the container 10 based on the output data of the load cell LC every time the input material is input into the container 10, and uses the input means 25, 26, 28. Get the input history of the input. For example, the CPU 23 can acquire the personal information of the supplier using the RFID reader 26. Further, the CPU 23 can acquire the type of the input using the key input unit 25. Further, the CPU 23 can acquire the input date and time of the input using the real time clock 28.

  Thereby, in the weighing device 100 of the present embodiment, it is possible to know afterwards which “who”, “when”, “what”, and “how much” is put into the container 10. Therefore, in the weighing apparatus 100 of the present embodiment, even when a plurality of input companies input various types of inputs into the container 10, the input date and time of the input, the input type, the input supplier, and the input of the input Appropriate correspondence between quantities can be specified. As a result, the weighing device 100 is significantly more convenient than the conventional example. For example, the container collection organization can charge the input processing cost to the input supplier.

  FIG. 4 is a diagram schematically showing the inside of the container used in the weighing device according to the embodiment of the present invention.

  As shown in FIG. 4, the container 10 ′ of the present embodiment has rectangular first, second, third, and fourth chambers 10 </ b> A, 10 </ b> B, 10 </ b> C, and 10 </ b> D (a plurality of regions) by a cross-shaped partition plate 15. It is divided into. As a result, the container 10 'includes first, second, third, and fourth chambers 10A, 10B, 10C, and 10D in which the types of inputs to be input are predetermined.

  Specifically, the first room 10A of the container 10 'according to the present embodiment is an area where "industrial waste" is to be input, as shown in FIG.

  Further, the second room 10B is an area where “aluminum”, which is a resource recovery product, is to be input.

  Further, the third room 10C is an area in which “iron scrap” that is a resource recovery product is to be input.

  Further, the fourth room 10D is an area in which “paper” that is a resource recovery product is to be input.

  Therefore, in this case, the above “list of input history and amount of input” is, for example, as shown in Table 2 below.

  Further, as shown in FIG. 4, the weighing device 100 is arranged so that each of the four load cells LC corresponds to each of the first, second, third, and fourth rooms 10A, 10B, 10C, and 10D. Has been. That is, each of the four load cells LC is arranged at the four corners of the container 10 '. In addition, as shown in FIG. 2, each of the output terminals of the four load cells LC is connected to the CPU 23 via the four A / D converters 21 corresponding thereto.

For this reason, it is considered that the CPU 23 can predict a room in which the input material is actually input by the operator based on the output data of each of the four load cells LC.
In other words, from the output data of each of the four load cells LC, the CPU 23 should be able to predict the position of the center of gravity on the plane of the container 10 ′ before and after the input of the load. It is considered that the room where the input is actually performed can be predicted.

  As described above, when the type corresponding to the room in which the input is actually performed (the room based on the prediction of the CPU 23) is different from the type of the input selected by the operator, the CPU 23 determines that the operator A warning can be issued.

  For example, the CPU 23 uses the speaker of the notification device 24 to indicate to the worker that “the input type is selected as paper, but the type corresponding to the room in which the input is currently input is the iron scrap. is. Can be issued.

  According to the present invention, it is possible to obtain a weighing device that can acquire the input history of the input every time the input is input into the container. Therefore, the present invention can be used as, for example, a container weighing device of a cargo handling vehicle that can load and unload containers.
