Garbage is collected by the garbage collector and the company or office is charged by the garbage collector. Therefore, when collecting garbage from a large number of companies or business establishments, the garbage collection company accurately grasps the weight of the garbage collected from which company or business establishment, and individual companies and business establishments. Needs to be clear.

For this reason, when the garbage stored in a specific container is put into a garbage box of a refuse collection vehicle, the load required for lifting the container is measured using a load cell, and the weight of the garbage is determined based on the load. Techniques for measuring have been proposed. However, according to this technique, in order to measure the weight of the garbage that is not stored in a specific container, the garbage must be stored in the container one by one, and the work efficiency of the garbage collection is significantly reduced.

On the other hand, the applicant of the present application has previously filed an application for a weight measuring device capable of accurately measuring the weight of refuse not stored in a specific container. (Japanese Patent Application No. 7-330603
However, since the weight measuring device according to the prior application is mounted on a refuse collection vehicle, the weight of refuse that can be loaded on the refuse collection vehicle is reduced by the weight of the weigh collection device. In addition, although the weight measuring device according to the prior application can be easily mounted on a newly produced garbage truck, it must be significantly modified to be installed on the existing garbage truck. Absent.

The article weight measuring device 100 shown in FIGS. 1 and 2 includes a load measuring unit 10 attached to a bottom portion of work shoes 4L and 4R worn by a worker 3 who transfers the refuse 2 to the refuse collection vehicle 1, The apparatus includes a weight calculating unit 20 and a totaling unit 30 attached to the waist of the worker 3.

As shown in FIG. 3, the load measuring means 10 corresponds to the first load cells 11L and 11R arranged at positions corresponding to the finger portions of the worker's feet and the base of the finger. The second load cell 12L,
12R and the third attached to the position corresponding to the heel part
And the load cells 13L and 13R. These load cells are individually connected to the weight calculating means 20 via signal cables 14 and 15, respectively. In addition, the signal cables 14 and 15 are attached to work clothes pants or the like worn by the worker, and are protected from interfering with the feet of the worker 3 and the collected dust 2.

The load measuring means 10 may be, for example, a method of measuring the load by using a strain gauge attached to a member which bends when a load is applied from the foot of the worker, or a shoe worn by the worker, in addition to the load cell. Various methods can be adopted, such as a method of measuring a pressure change of a fluid sealed in a sealed chamber provided in the above. Further, the load measuring means 10 may be attached to the sole of the shoe worn by the worker, or may be directly attached to the sole of the worker's foot, for example, in addition to being attached to an insole or a sock worn by the worker. A method of attaching can also be adopted.

The weight calculating means 20 uses a 32-bit C
It is a portable pocket computer with a built-in PU. The weight calculating means 20 is detachably attached to the waist belt of the worker, so that the physical load on the worker 3 is reduced and the worker 3 can easily operate. As shown in FIG. 4, the weight calculating means 20 has a first interface section 21 to which the signal cables 14 and 15 are detachably connected. The signal input to the first interface unit 21 from the load measuring unit 10 is processed by the central processing unit 22. The data processed by the central processing unit 22 is stored as a load value in the storage unit 23 and displayed on the display unit 24. Further, the control unit 25 that controls the operation of these units has various operation keys such as numeric keys operated by an operator. Then, the weight value of the article calculated by the weight calculating means 20 is transmitted to the counting means 30 such as a memory card via the second interface unit 26. The power supply unit 27 has a battery for supplying power to these units, and a switch for controlling ON / OFF of the power supply.

The tallying means 30 includes the weight calculating means 2
0, which is detachably attached to the weight calculating means 20.
The weight of the garbage calculated according to the above is stored and stored together with a tally code described later. Then, the counting means 30
Is removed from the weight calculating means 20 and attached to the external computer 40 shown in FIG. 2, the tally code stored in the tallying means 30 and the measured weight value of the garbage are downloaded to the external computer 40, and the billing is performed. Used in the calculation for

Next, a procedure for measuring the weight of the refuse to be collected using the article weight measuring apparatus 100 configured as described above will be described.

First, the worker 3 who collects garbage stands on the ground surface quietly with both feet at the start of the work, and operates the work start button of the weight calculating means 20. At this time, the sum of the loads applied to the load cells 11, 12, and 13 from the back of the feet of the worker is equal to the weight of the worker 3. As a result, the load value M1 obtained between time 0 and time T0 in the graph shown in FIG. 5 is equal to the weight value of the worker. Therefore, when the weight calculating means 20 confirms that the constant load value M1 has continued for a predetermined time or more, the weight calculating means 20 determines that the load value M1
Is regarded as the weight of the worker 3 and stored in the storage unit 23, and at the same time, the completion of the weight measurement is notified to the worker 3 by an alarm sound.

Next, the operator 3 operates the key of the weight calculating means 20, and inputs the total code of the company or the business office that performs the waste collection work. Thereafter, when the worker 3 lifts the refuse 2 to be transferred to the refuse collection vehicle 1, the load cell 1
The load values measured by 1, 12, and 13 are higher than M1 corresponding to the weight of the worker as shown in the graph of FIG. 5 between times T0 and T1. Then, the weight calculating unit 20 sequentially stores the total of the load values measured by the load cells 11, 12, and 13 in the storage unit 23 at a small time interval.

At this time, the load cells 11, 12, 1
Numerals 3 are arranged on both the left and right work shoes 4L, 4R worn by the worker 3 and distributed from a position corresponding to the toes of the worker 3 to a position corresponding to the heel. Thereby, even if the posture of the worker 3 changes, each load cell 11,
By calculating the sum of the load values applied to the loads 12 and 13, the value of the load value obtained by adding the weight of the refuse 2 lifted by the worker 3 to the weight of the worker 3 can be accurately measured.

On the other hand, when the worker 3 releases his / her hand from the garbage 2 to transfer the lifted garbage 2 to the garbage collection vehicle 1, the load value applied to the load cells 11, 12, and 13 from the feet of the worker 3 Is rapidly reduced from the maximum value M2 as shown between times T1 and T2 in the graph of FIG. Accordingly, when the weight calculation unit 20 confirms that the amount of decrease in the load value per unit time exceeds a predetermined value, it is regarded that the worker 3 has released his / her hand from the lifted refuse 2. Then, a value obtained by subtracting the weight M1 of the worker 3 from the load value data stored in the storage unit 23 is calculated and stored in the storage unit 23 as the weight of the garbage 2.

The load value measured by the load cells 11, 12, and 13 is affected by the acceleration generated in the dust 2 when the worker 3 lifts the dust 2. Therefore, the weight calculation unit 20 appropriately processes the change in the load value stored in the storage unit 23, and
Calculate the true value of. That is, the load cells 11, 1
By storing the load values measured by the storage units 2 and 13 in the storage unit 23, there is an advantage that the data of the load values can be arbitrarily processed and used for calculating the refuse weight.

Further, when the value of the load value measured by the load cells 11, 12, and 13 becomes equal to the weight M1 of the worker 3 again, the weight calculating means 20 deletes the load value data stored in the storage unit 23. Then, it returns to a state where the next refuse weight measurement can be started. At this time, the weight calculating means 2
0 emits an alarm sound to notify the worker 3 that the weight of the next refuse can be measured.

The weight data of each refuse 2 calculated by the weight calculating means 20 is stored in the totaling means 30 together with the totaling code. Then, when the worker 3 who has completed the garbage collection work removes the counting means 30 from the weight calculating means 20 and attaches it to the external computer 40 mounted on the garbage collection vehicle 1, the external computer 40 is stored in the counting means 30. Download the measured data. As a result, the total weight of the garbage collected from a specific company or business site is registered in the external computer 40 together with a tally code identifying the company or business site.

That is, according to the article weight measuring apparatus 100 of the first embodiment, the weight of the worker 3 is calculated from the load values measured by the load cells 11, 12, and 13 when the worker 3 lifts the dust 2. By reducing, worker 3
Can accurately calculate the weight of the refuse 2 lifted by the user. According to the article weight measuring device 100 of the first embodiment, it is not necessary to attach any device for measuring the weight of the refuse 2 to the refuse collection vehicle 1.
Does not reduce the weight of the loadable waste. Further, since there is no need to remodel the refuse collection vehicle 1, no remodeling cost is generated, and therefore, the article weight measuring device 100 of the first embodiment can be introduced at extremely low cost. In addition, the article weight measuring device 10 of the first embodiment
According to 0, the worker 3 can put the refuse 2 into the packing box of the refuse collection vehicle 1 from any position, for example, from the side of the refuse collection vehicle 1. Put garbage 2 on the platform scale
After the weight of the garbage is measured, the garbage collection work can be performed very efficiently without the need for any troublesome work such as lifting the garbage 2 again. Further, even when the large garbage 2 is lifted by two workers 3 with help, the weight of the large garbage 2 can be accurately measured from the load applied to each worker's foot.

Second Embodiment Next, an article weight measuring apparatus according to a second embodiment of the present invention will be described.

The above-described article weight measuring apparatus 100 is configured to automatically calculate the weight of the refuse 2 when the operator 3 releases his / her hand from the refuse 2, and the operator 3 operates the weight calculating means 20 by hand. It has an excellent advantage that the weight of the refuse 2 can be measured without performing. However, if the worker 3 walks with the refuse 2 for a long distance, the worker 3 may temporarily drop the refuse 2 on the ground surface G, take a short break, and then lift the refuse again to walk. In this case, according to the article weight measuring device 100 of the first embodiment, there is a possibility that the weight of the refuse 2 is measured redundantly. Therefore, the article weight measuring device according to the second embodiment is configured so that the weight calculating means 20 does not measure the weight of the refuse 2 except when the worker 3 comes near the refuse collection vehicle 1. Article weight measuring device 100
Is further improved.

That is, as shown in FIG. 1, the article weight measuring apparatus according to the second embodiment employs a worker 3
And a command signal sending means 60 for sending a command signal to the weight calculating means 20. The article weight measuring apparatus 100 according to the first embodiment comprises: It is added to.

The approach detecting means 50 detects that the worker 3 has approached the refuse collection vehicle 1 within a predetermined distance from the reflected echo of the emitted ultrasonic waves. The command signal transmitting means 60 emits a weak command radio wave from an antenna attached to the refuse collection vehicle 1.

Thus, when the worker 3 approaches the refuse collection vehicle 1 within a predetermined distance, the approach detecting means 50 reacts, and the command signal transmitting means 60 emits a command radio wave. Then, after receiving the command radio wave, the weight calculating means 20 calculates the weight of the refuse only when it is considered that the worker 3 has first released the hand from the refuse 2. Therefore, even if the worker 3 repeats the operation of lifting and lowering the garbage 2 at a place away from the garbage collection vehicle 1, it is possible to reliably prevent the weight of the garbage 2 from being overlapped and counted. .

The approach detecting means 50 recognizes, for example, changes in the intensity and position of infrared rays emitted from the body of the worker 3 instead of the method of detecting the approach of the worker 3 using ultrasonic waves. Various methods can be used, such as a method, a method in which the worker 3 detects an infrared beam by crossing the beam, and a method using a change in the intensity of an electric field or a magnetic field. The command signal transmitting means 60 can also transmit a command using, for example, an infrared pulse signal or an ultrasonic signal, in addition to transmitting a command signal using a weak radio wave.

Third Embodiment In the article weight measuring devices of the first and second embodiments described above, when the weight calculating means 20 considers that the worker 3 has released his / her garbage 2, the weight is calculated. It is configured to be. On the other hand, the article weight measuring device according to the third embodiment is configured such that when the command signal transmitting means 60 emits a radio wave for instructing weight calculation, the weight calculating means 20 immediately calculates the weight of the refuse 2. You. Thereby, the weight of the refuse 2 can be calculated and totaled when the worker 3 is lifting the refuse 2, so the effect of the acceleration acting on the refuse 2 when the worker 3 lifts the refuse 2 And the weight of the refuse 2 can be measured more accurately.

For example, if the operator 3 having the refuse 2 crosses the infrared beam and the command signal transmitting means 60 emits a radio wave for instructing the weight calculation, the operator 3 transports the refuse 2. The weight of the refuse 2 can be measured on the way, and the applicable range of the article weight measuring device of the third embodiment can be further expanded.

Fourth Embodiment An article weight measuring apparatus according to a fourth embodiment provides a weight calculation command to the weight calculating means 20 by operating a switch by the worker 3 himself who collects the refuse 2. It is said. Thereby, the weight of the refuse 2 can be measured at the optimal timing, so that the accuracy of the weight measurement can be further improved.

If the switches operated by the worker 3 are provided on both sides of the worker 3, for example, the worker 3 can tighten or loosen the side while holding the garbage 2 in his / her hand. The switch can be turned ON / OFF. In addition, a switch provided inside the shoe worn by the worker 3 can be turned on / off with a toe. Further, a switch operation can be performed by applying a load to the load cell 11 provided inside the shoe worn by the worker 3 using a toe. In addition, a voice recognition device may be added to the weight calculating means 20 to provide a voice switch for controlling the operation by the voice of the worker 3. Furthermore, the switch can be turned on simultaneously with the input of the refuse 2 by a photoelectric switch, a proximity switch, a contact switch, or the like provided at the refuse input port of the refuse collection vehicle 1.

Fifth Embodiment The article weight measuring apparatus according to the first to fourth embodiments is
Literally, the weight of garbage 2 was calculated and totaled. On the other hand, the article weight measuring apparatus according to the fifth embodiment has a counting function for counting the number of refuse 2 transferred by the worker 3 to the refuse collection vehicle 1, and the article weight measuring apparatus according to the first to fourth embodiments. It is one added to the measuring device. That is, some municipalities have adopted a system in which a fee is charged according to the number of pieces of garbage packed in a garbage bag having a predetermined capacity. In this case, it is sufficient that the worker 3 counts the number of the refuse 2, but it is difficult for the plurality of workers 3 to collect a large amount of refuse while counting the number of the refuse accurately.

Therefore, in the article weight measuring apparatus of the fifth embodiment, the weight calculating means 20 determines that the amount of decrease per unit time of the load value measured by the load cells 11, 12, 13 exceeds a predetermined value. When confirmed, it is considered that the worker 3 has released his / her hand from the lifted refuse 2, and the count value of the number of refuse stored in the storage unit 23 is increased by one. Thus, according to the article weight measuring device of the fifth embodiment, the number of refuse 2 collected by the worker 3 can be accurately recorded.

The article weight measuring apparatus according to the fifth embodiment also receives the command signal transmitted from the command signal transmitting means 60 as described above, or
It is needless to say that the number of refuse can be counted by a switch operation or the like by the user.

As described above, each embodiment of the article weight measuring apparatus according to the present invention has been described in detail. However, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in each of the above-described embodiments, the case of transferring the refuse 2 to the refuse collection vehicle 1 is described as an example. It goes without saying that the article weight measuring device of the present invention can also be used for measurement. In the above description, the worker 3 stands on the ground surface G. However, the ground surface G refers to, for example, a road surface when garbage collection work is performed on a road, and a ground surface when garbage collection work is performed on a sidewalk. The sidewalk refers to the floor of the warehouse when performed in the warehouse, and the stairs when performed on the stairs, and does not limit the location or position.

[0048]

As is apparent from the above description, according to the article weight measuring apparatus of the present invention, the load value applied to the ground surface from the feet of the worker is measured by the load measuring means, and When the weight of the article lifted by the worker is calculated by subtracting the weight of the worker from the load value measured by the load measuring means when the article is lifted, the weight of the article can be accurately calculated. . Thus, according to the present invention, for example, since it is not necessary to attach a load measuring means to the refuse collection vehicle, the weight of refuse that can be loaded on the refuse collection vehicle does not decrease. In addition, since it is not necessary to modify the garbage truck to install the load measuring means, not only can the cost of remodeling the garbage truck be significantly reduced, but it can be easily adapted to any type of garbage truck. Can be. Further, according to the present invention, it is not only not necessary to prepare a platform scale used for measuring the weight of refuse,
Since there is no need to perform the labor twice, such as lifting the garbage from the weighing platform after placing the garbage on the weighing platform and measuring the weight, the garbage collection operation can be performed extremely efficiently. Further, according to the present invention, the worker of the garbage collection can put the garbage into the packing box of the garbage collection vehicle from an arbitrary position, so that the physical burden on the worker can be further reduced. In addition, since the weight of waste to be collected cannot be measured efficiently, the present invention is also applicable to local governments that adopt a method in which the waste collection fee is determined by the number of waste packed in a garbage bag of a predetermined capacity. By adopting the article weight measuring device, it is possible to construct a system that accurately collects garbage charges according to the weight of garbage discharged. According to the present invention, when collecting garbage from a large number of companies or business establishments, it is possible to accurately grasp which company or business establishment has collected how much garbage and how much garbage has been collected. It is possible to make accurate the amount of the refuse collection fee charged to each company or office.
