Basket device for container bag

Abstract

To enable prompt loading and carrying-out without exceeding a maximum loading capacity of a transportation vehicle while accurately confirming the weight during filling a bag with an object even for a container bag to which waste is input and which is carried out.SOLUTION: A container bag (flexible container) 30 is opened and mounted onto an inner basket 20, which is placed on a top plate 11T of a base 11 that incorporates a weighing device 41 in an outer basket 10. The weight value of the inner basket 20 including the flexible container 30 measured by a weighing device 40 on the basis of output signals from a weight sensor LS installed on the top plate 11T is corrected to the weight value of the flexible container 30 excluding the weight of the inner basket 20 body by the weighing device 40 and displayed on a display unit 41 located on the front side of the base 11. While confirming the weight value of the flexible container 30 displayed on the display unit 41, a worker puts waste into the flexible container 30, stops the input of the waste at a time point when the displayed weight value does not exceed the predetermined maximum weight value of the flexible container 30, and loads the flexible container 30 filled with the waste onto a transportation vehicle to carry out the bag.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] Embodiments of the present invention relate to a basket device for a container bag.

Background Art

[0002] Industrial wastes such as metal scraps and wood scraps generated at a construction site are put into a flexible container bag (commonly called a "flexible container" or also referred to as a "container bag") and discarded. The flexible container filled with industrial waste is loaded onto a vehicle such as a truck (transport vehicle) by a collection and transportation operator who collects and transports the flexible container and is carried out of the construction site. When carrying out industrial waste, the weight of the flexible container is measured so as not to exceed the maximum load capacity of the transport vehicle, and then it is loaded onto the transport vehicle.

[0003] Generally, the weighing of a flexible container is performed using a measuring instrument such as a crane scale. In the case of a crane scale, since the weight is measured while being lifted by a crane, it takes time for the weighing of the flexible container, loading onto the transport vehicle, and carrying out. Furthermore, since the weight of the flexible container cannot be confirmed in advance (before the loading operation onto the transport vehicle), if the maximum load capacity of the transport vehicle is exceeded by weighing, extra work such as extracting a part of the industrial waste put in the flexible container and then reweighing must be done.

[0004] On the other hand, a "flexible container weighing device" as a device for weighing a flexible container filled with rice is in practical use. In the case of the "flexible container weighing device", a plate-shaped weighing plate on which the flexible container is placed for weighing and a display for displaying the weight measured by the weighing plate as a numerical value are separately configured, and it is only used for weighing the flexible container in a state where fine-grained objects such as rice are put in and do not collapse.

[0005] For this reason, the "plastic container scale" is not only unsuitable for weighing plastic containers that are easily deformed due to the inclusion of industrial waste with various shapes, materials, and weights (such as a part of the deformed plastic container hanging down from the edge of the weighing plate due to uneven contents), but also after loading the plastic container containing industrial waste onto the "plastic container scale" for weighing using a crane or forklift and then reloading it onto a transport vehicle using a crane or forklift again, it takes more time to unload the plastic container than in the case of the crane scale described above. Also, as described above, when the maximum loading capacity of the transport vehicle is exceeded, extra operations such as reweighing must be performed.

MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0011] (Configuration of Embodiment) Figure 1 is a perspective view showing the external configuration of the basket device 1 for a container bag according to the embodiment.

[0012] The basket device 1 for a container bag includes an outer basket 10 that can be pushed and pulled by a user (operator) to move on uneven ground, and an inner basket 20 that is placed inside the outer basket 10 with a container bag (here, a "flexible container") 30 attached thereto.

[0013] As shown in the figure, the inner basket 20 is sized such that the container bag 30 can be mounted therein with its opening open, and the outer basket 10 is sized to be one size larger (larger than the inner basket 20) than the inner basket 20 that can surround and place the inner basket 20.

[0014] Figure 2 is a perspective view showing a partially transparent view of the external configuration of the outer basket 10 of the basket device 1 for a container bag.

[0015] FIG. 3 is a perspective view showing a partially transparent view of the configuration of the inner basket 20 of the basket device 1 for a container bag.

[0016] FIG. 4 is a perspective view showing a partially transparent view of the configuration of the inner basket 20 with the container bag 30 of the basket device 1 for a container bag mounted thereon.

[0017] <Configuration of the outer basket 10> In the basket device 1 for a container bag shown in FIG. 1 and the outer basket 10 shown in FIG. 2, the front side in the illustration is defined as the front of the basket device 1 and the outer basket 10, the back side in the illustration is defined as the back, and the right side and the left side in the illustration are defined as the right side surface and the left side surface, respectively, for explanation.

[0018] The outer basket 10 has a rectangular bottom plate of the outer basket 10 and a rectangular parallelepiped base 11 incorporating a weighing device 40. At the four corners of the lower surface of the base 11, stopper-equipped free casters 12 each having, for example, rubber tires are provided.

[0019] Also, at the four corners of the top plate 11T (bottom plate of the outer basket 10) of the base 11, columns 13 extending upward, for example, to a height exceeding that of the inner basket 20 are erected. At the upper and middle portions of each column 13, upper surrounding bars 14a, 14b, 14c and middle surrounding bars 15a, 15b, 15c that connect across between the left and right columns 13 on the three sides of the right side surface, left side surface, and back surface of the outer basket 10 are provided.

[0020] Also, at the middle portions of the left and right columns 13 on the front surface of the outer basket 10, a front surrounding bar (openable and closable front surrounding bar) 16 that can be opened and closed as shown by an arrow P across between the columns 13 is provided. The openable and closable front surrounding bar 16 is provided so as to be openable and closable by a user's operation with a hinge portion 16H provided on, for example, the right column 13 as a fulcrum. In a state where the front surface of the outer basket 10 is closed by the openable and closable front surrounding bar 16, the tip portion of the front surrounding bar 16 that opens and closes is detachably fitted and fixed to a U-shaped bar receiving portion (bracket) 16B provided at the middle portion of the left column 13.

[0021] That is, the upper surrounding bars 14a, 14b, 14c, the intermediate surrounding bars 15a, 15b, 15c, and the opening / closing front surrounding bar 16 function as enclosures (14a to 14c, 15a to 15c, 16) for the inner basket 20 in the outer basket 10, preventing the inner basket 20 placed on the outer basket 10 from coming off the base 11, and facilitating the placement and removal of the inner basket 20 on and from the base 11 from the front of the outer basket 10.

[0022] At four locations near the corners of the top plate 11T of the base 11, load cells LS(1) to LS(4) are provided which output electrical signals (voltages) corresponding to the distortion of the top plate 11T with respect to the lower surface of the top plate 11T, and the output signals of the respective load cells LS(1) to LS(4) are input to the weighing device 40.

[0023] The weighing device 40 measures the weight of an object (here, the inner basket 20 with the flexible container 30 attached) placed on the top plate 11T of the base 11 based on the output signals from the four load cells LS(1) to LS(4) which are weight sensors LS, and digitally displays on the display unit 41 the weight value of the flexible container 30 obtained by correcting the measured weight value of the inner basket 20 (including the flexible container 30) with the weight value (known) of the inner basket 20 body.

[0024] The housing of the weighing device 40 is attached to the back side of the front plate of the base 11 with the display unit 41, which is, for example, a segment type liquid crystal display device, the notification unit 42, which is a buzzer, and the operation unit 43, which is a volume or push switch, exposed on the front plate of the base 11.

[0025] The operation unit 43 inputs, in a state where the inner basket 20 with the flexible container 30 attached is placed on the base 11, the weight value (known) of the inner basket 20 body as an offset value according to a user operation, and instructs the weighing device 40 to perform calibration for correcting the measured weight value.

[0026] In the outer basket 10, the top plate 11T of the base 11 is made of, for example, an iron plate, and the sides, bottom surface, upper surrounding bars 14a, 14b, 14c, middle surrounding bars 15a, 15b, 15c, and the opening / closing front surrounding bar 16 excluding the top plate 11T of the base 11 may be made of a material such as stainless steel, for example.

[0027] <Configuration of the inner basket 20> As shown in FIGS. 3 and 4, the inner basket 20 is configured as a rectangular parallelepiped basket with an open top surface sized to be mountable within the inner basket 20 with the flexible container 30 open. For example, the framework of the inner basket 20 forming the sides of the rectangular parallelepiped may be constructed using stainless steel angle frames, and the four side plates 23a to 23d and the bottom plate 23e may be constructed using stainless steel flat plates.

[0028] On the inner surfaces of the upper right frame 21a and the upper left frame 21b forming the upper sides of the opposing right side plate 23a and left side plate 23b of the inner basket 20, for example, two hook-shaped hooks 22 are provided swingably at two locations each.

[0029] As shown in FIG. 4, the hook 22 has a function of hooking the suspension belts 31a, 31b provided at the edges of the opening of the flexible container 30 to hold the opening of the flexible container 30 in an open state and mounting the flexible container 30 within the inner basket 20.

[0030] Also, as shown in FIG. 3, all inner surfaces including the four side plates 23a to 23d and the bottom plate 23e of the inner basket 20 are covered by attaching or applying a low-friction material FR such as a fluororesin to minimize friction with the surface of the flexible container 30.

[0031] <Configuration of the weighing device 40> FIG. 5 is a block diagram showing the configuration of the electronic circuit of the weighing device 40 provided within the base 11 of the container bag basket device 1.

[0032] The weighing device 40 includes a control unit (CPU: Central Processing Unit) 44.

[0033] In addition to the display unit 41, notification unit 42, and operation unit 43 described above, a storage unit 45 and a voltage measurement unit 46 are connected to the control unit 44.

[0034] The voltage measurement unit 46 inputs the output signals from the four load cells LS(1) to LS(4), which are the weight sensors LS described above, and measures the voltage (the voltage corresponding to the weight of the object placed on the top plate 11T of the base 11), and outputs the measured voltage value (digital value) to the control unit 44.

[0035] The control unit 44 controls the operations of each part of the circuit according to a program pre-stored in the storage unit 45, for example, in response to an input signal corresponding to a user operation from the operation unit 43 or an input signal of a voltage value (digital value) from the voltage measurement unit 46.

[0036] The weighing device 40 has a battery power source BT such as a rechargeable battery or a dry battery, and the operating power is supplied from the battery power source BT to each part of the circuit.

[0037] (Operation of the Embodiment) Next, the operation of the basket device 1 for the container bag of the embodiment will be described.

[0038] Here, it is assumed that the industrial waste taken out from the construction site is carried out using the basket device 1 for the container bag of the embodiment.

[0039] As shown in FIG. 4, the user (worker) hooks the suspension belts 31a and 31b of the container bag (flexible container) 30 on the hook 22 inside the inner basket 20, and attaches the flexible container 30 to the inner basket 20 with its opening open.

[0040] As shown by the arrow P in FIG. 2, the user opens the opening / closing front surrounding bar 16 in the enclosures (14a to 14c, 15a to 15c, 16) of the outer basket 10, and places the inner basket 20 with the flexible container 30 attached on the top plate 11T of the base 11. Then, as shown in FIG. 1, the opening / closing front surrounding bar 16 is closed to surround the inner basket 20 so that it does not come off the base 11.

[0041] The user operates the operation unit 43 of the weighing device 40 to input the weight value of the inner basket 20 body, which is known, as an offset value (the offset value is displayed on the display unit 41), and instructs calibration.

[0042] Based on the offset value input from the operation unit 43, the control unit 44 corrects the weight value (the weight value of the entire inner basket 20) being measured based on the voltage value input from the weight sensor LS via the voltage measurement unit 46, and causes the display unit 41 to display "0" (t: ton (kg: kilogram is also acceptable)). After that, as the weight of the inner basket 20 including the freight container 30 being measured increases, the control unit 44 causes the display unit 41 to display the weight value (which has become the weight value of the freight container 30 excluding the weight of the inner basket 20 body by correction).

[0043] The user pushes and pulls the outer basket 10 to move it to the place where the waste is put into the freight container 30 in the inner basket 20, and operates the stopper of the free caster 12 to stop the movement of the outer basket 10.

[0044] The user appropriately uses a small heavy machine or the like to put the waste into the freight container 30 in the inner basket 20. At this time, while checking the weight value of the freight container 30 displayed on the display unit 41, the user puts the waste into the freight container 30 and stops putting in the waste when the displayed weight value does not exceed the maximum weight value of the freight container 30 predetermined based on, for example, the maximum loading capacity of the transport vehicle.

[0045] At this time, the waste put into the freight container 30 is, for example, waste with miscellaneous shapes, materials, and weights, and when the freight container 30 is deformed due to unevenness of its contents, the surface of the freight container 30 may come into contact with the side plates 23a to 23d and the bottom plate 23e of the inner basket 20 unevenly.

[0046] Even in such a case, due to the action of the low-friction material FR provided on all the inner surfaces including the side plates 23a to 23d and the bottom plate 23e of the inner basket 20, all the weights unevenly applied to the side plates 23a to 23d are redirected downward, that is, in the direction of the bottom plate 23e. Therefore, the load of the plastic container 30 containing waste can be sufficiently applied to the bottom plate 23e and correctly included in the weight of the inner basket 20.

[0047] While checking the exact weight of the plastic container 30 containing waste on the display unit 41, the user can prepare the plastic container 30 with waste without exceeding the maximum load capacity of the transport vehicle.

[0048] In addition, the user operates the operation unit 43 of the weighing device 40 in advance to input and store the maximum weight value of the plastic container 30 to be mounted on the inner basket 20 in the storage unit 45. When the control unit 44 determines that the weight value displayed on the display unit 41 has reached a weight value (notification weight value) obtained by subtracting a predetermined weight value (for example, 5 kg) from the maximum weight value of the plastic container 30 stored in the storage unit 45, the buzzer of the notification unit 42 may be operated to notify the user of the timing to stop the input of waste into the plastic container 30.

[0049] The plastic container 30 after the input of waste is lifted out of the inner basket 20 using, for example, a crane, loaded onto a transport vehicle, and carried to the disposal site of industrial waste.

[0050] (Summary of the embodiment) According to the basket device 1 for a container bag of the embodiment, the inner basket 20 with the container bag (plastic container) 30 opened and mounted is placed on the top plate 11T of the base 11 incorporating the weighing device 40 of the outer basket 10. The weighing device 40 corrects the weight value of the inner basket 20 including the plastic container 30 measured based on the output signal from the weight sensors LS (load cells LS(1) to LS(4)) provided on the top plate 11T to the weight value of the plastic container 30 excluding the weight of the inner basket 20 itself, and displays it on the display unit 41 exposed on the front of the base 11.

[0051] While checking the weight value of the flexible container 30 displayed on the display unit 41, the user (operator) puts the waste into the flexible container 30 and stops putting in the waste when the displayed weight value does not exceed the maximum weight value of the flexible container 30 determined in advance. Then, the flexible container 30 filled with the waste is loaded onto a transport vehicle and carried out.

[0052] Since the outer basket 10 can be moved to and stopped at an arbitrary location by the user's pushing and pulling even on uneven ground by the stopper-equipped free caster 12 provided on the lower surface of the base 11 using rubber tires, one container bag basket device 1 can be used in the process of putting the waste (object) into the flexible container 30, weighing it during the putting-in process, and loading the flexible container 30 filled with the waste onto a transport vehicle.

[0053] Also, the inner surfaces of the side plates 23a to 23d and the bottom plate 23e of the inner basket 20 are made of a low-friction material FR, and the friction with the surface of the flexible container 30 into which the waste has been put is minimized. Therefore, even when the surface of the flexible container 30 comes into uneven contact with the side plates 23a to 23d and the bottom plate 23e of the inner basket 20 due to the shape or displacement of the waste in the flexible container 30, the load of the flexible container 30 can be sufficiently applied to the bottom plate 23e of the inner basket 20.

[0054] In the above-described embodiment, it has been described that the object to be put into and carried out in the container bag (flexible container) 30 is waste. However, it goes without saying that the object is not limited to waste, and all objects that can be put into and carried out in the flexible container 30, such as earth and sand, crops, and manufactured products, can be the object.

[0055] Therefore, according to the container bag basket device 1 of the embodiment, even for a container bag for putting in and carrying out waste, it is possible to quickly load and carry out the object while accurately checking the weight without exceeding the maximum loading capacity of the transport vehicle.

[0056] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
