Description

  The present invention relates to a crane weight rank determination apparatus that can be used by being hung on a hook of a suspension type transportation device such as a crane and can automatically determine the weight rank of an individual or a lump of sorting objects. .

In general, harvested agricultural products are sorted based on weight and shipped to the market by packing together for each grade.
In this case, the producer has to select individual agricultural products in advance based on their weights before shipping the agricultural products.
A conventionally known weight rank sorting apparatus, for example, places a plurality of sorting objects on a sorting apparatus having a weighing function for each container, and each time an operator picks up the sorting objects one by one from the container, The weight rank is configured to be notified to the worker by means such as character display or voice output, and the user selects a container in which a plurality of objects to be sorted are accommodated. If it can be lifted, it is possible to sort the objects to be sorted without hindrance.
However, when individual sorting objects are large and heavy, such as radishes, pumpkins, and Chinese cabbages, it is not easy for an operator to lift a container containing a plurality of sorting objects. Such a conventionally known weight rank sorter cannot be used for sorting.

In this case, the operator picks up the objects to be sorted one by one and measures them with a scale, or uses a large sorter equipped with a facility for automatically transporting the objects to be sorted. Regardless, methods such as sorting work were taken.
In the former case, there is a problem that it is difficult to improve the efficiency of the sorting operation. In the latter case, it is difficult to secure the installation place because the sorting device is large, and the sorting device itself is expensive. Farmers of scale had a problem that it was difficult to introduce a sorting device.

According to the first aspect of the present invention, when a container (suspended object) containing a plurality of selection objects that are too heavy to be lifted manually is lifted by a crane, The weight of the lowered object can be measured. And in invention of Claim 1, by providing an arithmetic processing part and a memory | storage part, it is in the variation | change_quantity of the measured value in the measurement part at the time of taking out one selection target object from the to-be-lifted object lifted by the crane. Based on this, the weight rank of the selected sorting object can be determined. Also, by providing the output display unit, the operator can know the weight rank determination result by visually confirming on the spot.
Therefore, according to the first aspect of the present invention, even when the container (the object to be lifted) in which a plurality of selection objects are stored cannot be lifted manually because the weight of each individual selection object is large, From the state in which the object to be lifted is lifted using a crane, it is possible to pick up one sorting object, determine the weight rank of the sorting object by a subtraction method, and notify the operator.
In this case, compared with the case where the weight rank of each sorting object is judged while performing the work of carrying and placing each sorting object one by one manually to a conventional measuring instrument or weight rank sorting device. Thus, the work efficiency of the weight rank determination work can be dramatically improved.
That is, according to the first aspect of the present invention, it is possible to omit the operation of manually transporting each individual sorting object one by one to a conventionally known weighing instrument or weight rank sorting device, so that the time required for the sorting work can be reduced. Can be shortened.
Further, in this case, since the chance of the operator touching the sorting object can be surely reduced, the risk of the sorting object being damaged or soiled can be reduced. In particular, when the sorting object is easily damaged by human touch such as agricultural products or marine products, it is possible to suitably suppress the deterioration of the quality of the sorting object.
Furthermore, since the invention described in claim 1 is an apparatus configured separately from the crane, the weight rank determination function can be added to the existing crane only when necessary. In this case, there is no need to remodel or add parts to the existing crane, so the cost for introducing the weight rank determination function to the site of the sorting operation can be made extremely low.

According to the second aspect of the invention, in addition to the same effect as that of the first aspect of the invention, the output display unit can be changed to an easily viewable direction according to the standing position of the operator.

  According to the invention described in claim 3, it is possible to inform the operator of the weight rank determination result of the selection object picked up from the suspended object by voice. In this case, the operator can know the weight rank determination result of the selection object without looking at the output display unit. As a result, when the weight rank is selected, the operator does not need to look at the output display unit in order to know the determination result of the weight rank, so that the selection operation can be performed more efficiently.

According to the invention described in claim 4, it is possible to inform the operator of the weight rank determination result of the selection object picked up from the suspended object by voice.

According to the fifth aspect of the present invention, it becomes easy to confirm the weight rank determination result of the selection object at a position away from the crane weight rank determination apparatus or record the information as electronic data. This facilitates the management of the shipping status, inventory management, or distribution status of the sorting object.

According to the sixth aspect of the present invention, since the weight rank determination result of the selection target can be output as a printed matter, the work of recording and storing the weight rank determination result can be reduced. In addition, for example, the weight rank determination result of each sorting object can be individually printed and output. For example, the weight rank determination result can be printed on a label paper that can be attached with an adhesive, so that the weight of each sorting object can be printed. The rank determination result can be attached to each sorting object. In this case, since the weight rank of the sorting object for which the sorting operation has been completed can be clearly specified, it is possible to prevent the determination result from becoming unknown.

  Hereinafter, a crane weight rank determination apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.

First, an outline of a crane weight rank determination apparatus according to the present embodiment will be described with reference to FIGS. 1 to 3.
FIG. 1 is a conceptual diagram showing a usage state of a crane weight rank determination apparatus according to an embodiment of the present invention, and FIG. 2 is a conceptual diagram of the crane weight rank determination apparatus according to an embodiment of the present invention. FIG. 3 is a system configuration diagram of the crane weight rank determination apparatus according to the embodiment of the present invention.
As shown in FIG. 1, the crane weight rank determination device 1 according to the embodiment of the present invention is a conventionally known suspension type conveyance device, for example, a hooking portion 18 provided in a crane 15, for example, Each time one picking object 13 is picked up from the suspended object 14 that is detachably mounted and lifted by the crane 15, the weight rank of the selecting object 13 is determined, and the determination is made to the operator or outside. It is configured to notify the result.
As shown in FIGS. 2 and 3, the crane weight rank determination apparatus 1 according to the present embodiment has, for example, vertical and vertical directions of the casing-like main body 20 made of synthetic resin or metal. The upper latching portion 21 and the lower latching portion 22 are provided on the side surface of the main body 20, and an output display for displaying the determination result of the weight rank of the selection target 13, input setting data, and the like in the center of the main body portion 20. A unit 5 and an input setting unit 7 including operation buttons for performing input setting work are provided.

Moreover, the crane weight rank determination apparatus 1 according to the present embodiment is suspended and held in the main body portion 20 by a lower latching portion 22 (not shown in FIG. 3) as shown in FIG. In addition to the weighing unit 2 that measures the load of the suspended object 14, the calculation processing unit 4 and the memory unit 3 are provided.
It should be noted that the data input setting work such as the weight rank determination reference data 8 stored in the memory unit 3 shown in FIG. 3 and the audio output data 9 stored as necessary is used for the crane according to the present embodiment. When it is not necessary to directly perform in the weight rank determination apparatus 1, it is not always necessary to provide the input setting unit 7. More specifically, a storage medium can be connected to the arithmetic processing unit 4, and the weight rank determination reference data 9 input and set in advance by an external personal computer or the like is connected to the crane via a removable storage medium. When configured to be able to be provided to the industrial weight rank determination apparatus 1, the input setting unit 7 is unnecessary.

Furthermore, the measuring unit 2 includes, for example, a load cell that converts a load (force) into an electric signal, for example, a load cell, and as shown in FIG. The load of the suspended object 14 that is suspended and held via the weight rank determining apparatus 1 can be measured.
In addition, in the crane weight rank determination apparatus 1 according to the present embodiment, the load of the suspended object 14 that is suspended and held by the lower hooking portion 22 (see FIGS. 1 and 2) is measured. The configuration will be collectively referred to as the weighing unit 2. The measurement data obtained by the measuring unit 2 is transmitted to the arithmetic processing unit 4 in the main body unit 20 by wire or wirelessly.
As shown in FIG. 3, the crane 15 that lifts the suspended object 14 includes a drive mechanism 16, and operates the operation unit 17 connected to the drive mechanism 16 to raise and lower the suspended object 14. It is configured so that it can be operated freely.

An example of a procedure for determining the weight rank of the selection target 13 in the crane weight rank determination apparatus 1 according to the present embodiment will be described in detail with reference to FIGS.
FIG. 4 is a flowchart showing a procedure for determining the weight rank of the selection object by the crane weight rank determination apparatus according to the present embodiment. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted.
In order to sort the weight rank of the sorting object 13 by using the crane weight rank determination apparatus 1 according to the present embodiment, first, as shown in FIG. 14 is moved to the place where 14 is located, and the upper hooking portion 21 of the crane weight rank determination apparatus 1 according to the present embodiment is hooked and attached to the hooking portion 18 (step S0).
Thereafter, for example, a hanging wire 24 or the like for hanging the suspended object 14 is hung on the lower hanging portion 22, and then the driving mechanism 16 is operated by the operating portion 17 by the crane 15. The suspended object 14 is lifted (step S1). And the total weight of the to-be-suspended object 14 suspended by the downward latching part 22 in the measurement part 2 is measured, More specifically, the suspension wire 24 suspended by the downward latching part 22, and a container 12 and the total weight of the plurality of selection objects 13 are measured (step S2), and the measurement data is transmitted to the arithmetic processing unit 4 by radio or wire. The measurement data measured in step S2 is set as a reference value (zero value) when calculating the weight of the selection target 13 by the subtraction method in the arithmetic processing unit 4 (step S3).

Furthermore, when one sorting object 13 accommodated in the container 12 is picked up by an operator (not shown) from this state (step S4), the calculation processing unit 4 uses the measurement data in the measurement unit 2 as a reference. The amount of decrease in weight from the value (zero value) is calculated, and this decrease in weight is recognized as the weight of the selection object 13 picked up by the operator (step S5).
On the other hand, since the weight rank determination reference data 8 for determining the weight rank of the selection target 13 is stored in the memory section 3 connected to the arithmetic processing section 4, 1 obtained in the previous step S5 is stored. The weight data of the two sorting objects 13 and the weight rank determination reference data 8 are compared in the arithmetic processing unit 4 (step S6), and the weight rank of the sorting object 13 taken up by the operator in the previous step S3 is determined. Monkey (step S7).
The weight rank determination result obtained in step S7 is displayed on the output display unit 5 using characters, symbols, phrases, or the like (step S8), and the operator visually observes the display on the output display unit 5. The weight rank of the selection object 13 picked up from the container 12 by itself in the previous step S3 can be known.

At this time, the weight of the selection target 13 may be displayed on the output display unit 5 together with the weight rank determination result of the selection target 13.
And the several selection target object 13 accommodated in the container 12 suspended by the crane 15 is repeated by repeating the process from step S4 to step S8 among the processes in the above-mentioned step S1 to step S8. Can be determined sequentially one by one.
In FIG. 4, the case where the weight measurement data measured in step S <b> 2 is set as a reference value and the weight of each selection target 13 is calculated by a subtraction method is described as an example. In addition, each time one picking object 13 is picked up from the container 12, the weighing unit 2 measures the total weight of the suspended object 14 suspended from the lower hanging part 22 of the crane weight rank determination apparatus 1, and calculates the weight. The processing unit 3 employs a method of subtracting the weight after picking up one sorting object 13 from the weight before picking up one sorting object 13 to obtain the weight of one sorting object 13. Also good.

As an example of the use state of the crane weight rank determination apparatus 1 according to the present embodiment shown in FIG. 1, a large number of radishes as sorting objects 13 are placed on the car as the container 12. A state is shown in which the object is suspended and held by the lower latching portion 22 of the crane weight rank determination apparatus 1 via the suspension wire 24.
Conventionally, after harvesting daikon from the field, wash the soil and dirt adhering to the surface with water, dry the water on the surface of the radish, select based on the weight of each, pack it to the market Shipped.
The size of the radish supplied to the market varies, but some of the larger radishes exceed 1 kg, and it is difficult to manually lift and move the container 12 containing many such heavy vegetables. .
Therefore, the radish sorting operation is performed completely automatically by using a large automatic sorting device regardless of the manual operation, or the workers are taken one by one from the cage car as the container 12 as shown in FIG. Therefore, it is necessary to carry the radish to a known weight rank sorting device and sort the weight rank.

In the former case, since the sorting operation does not require manual labor, the work efficiency is improved, but an expensive stationary type large-sized sorting device (see, for example, Patent Document 3) is necessary, and such a device is installed. For this reason, it is difficult for small and medium-sized farmers to introduce a sorting device.
In the latter case, although a large-scale device is not necessary, the device disclosed in Patent Document 1 cannot be used. Therefore, in order to select a single radish, a car that is a container 12 is conventionally known. The radish is transported to the weight rank sorting apparatus, and the weight rank is sorted. Thereafter, the weight rank sorted radish is picked up from the conventionally known weight rank sorting apparatus and transferred to another container 12 or packed in a box. There was a need.
In this case, as compared with the case where the sorting operation is performed using the apparatus disclosed in Patent Document 1, the carrot as the container 12 and the radish as the sorting object 13 are picked up to the conventionally known weight rank sorting apparatus. An extra work is required each time, and it is difficult to improve the work efficiency of the sorting work of the sorting object 13.
In view of such circumstances, the inventors have conventionally used an apparatus as disclosed in Patent Document 1 by adding a function of determining the weight rank to an existing crane weighing machine as a result of intensive studies. Even with respect to the sorting object 13 that could not be performed, the sorting object 13 of the sorting object 13 is simply taken out from the container 12 containing a large number of sorting objects 13 one by one. We succeeded in making it possible to determine the weight rank.

  Moreover, according to the crane weight rank determination apparatus 1 according to the present embodiment, by having the operations and effects as described above, the opportunity for the operator to touch the selection object 13 can be reliably reduced. The risk of the selection target 13 being damaged or fouled can be reduced. In particular, when the sorting object 13 is likely to be damaged when touched by human hands, such as agricultural products and marine products, the weight rank determination device 1 for crane according to the present embodiment is used. By performing the sorting operation, the opportunity for the operator to touch the sorting object 13 can be surely reduced, so that the deterioration of the quality of the sorting object 13 can be suitably suppressed.

Here, another function of the crane weight rank determination apparatus 1 according to the present embodiment will be described.
In the crane weight rank determination apparatus 1 according to the present embodiment, although not particularly illustrated, the direction of the output display unit 5 may be changeable. More specifically, for example, the output display unit 5 may be attached to the main body unit 20 via a support arm (not shown) so that the attachment angle of the output display unit 5 with respect to the main body unit 20 can be changed. In this case, the orientation of the output display unit 5 can be changed so that it is easy to see from the operator's standing position.
In this way, by configuring the output display unit 5 so that the orientation of the output display unit 5 can be changed, the visibility of the output display unit 5 by the operator is improved during the sorting operation of the sorting target 13, and the work efficiency of the sorting work is improved. Can be increased.
In addition, as a specific method of notifying the operator of the weight rank determination result of the selection target 13 using the output display unit 5, for example, the weight rank of the selection target 13 is shown on the output display unit 5, for example, By displaying characters, symbols, phrases, etc. such as “S”, “M”, “L”, “LL”, “non-standard”, the operator can visually check these characters, symbols, phrases, etc. It is good to comprise so that the judgment result of the weight rank of the selection object 18 picked up by itself can be known.

Furthermore, as shown in FIG. 3, the crane weight rank determination apparatus 1 according to the present embodiment outputs the sound output unit 6 and the memory unit 3 from the sound output unit 6 in addition to the output display unit 5. Audio output data 9 may be provided.
The audio output data 9 indicates the weight rank of the sorting object 13, for example, characters, symbols, phrases, etc. such as “S”, “M”, “L”, “LL”, “non-standard”. This is voice data read out. This voice data may be voice synthesized by a personal computer or the like, or may be recorded voice generated by a person.
