Embodiments of the present invention will be described with reference to the accompanying drawings. In each figure, those having the same reference numerals have the same or similar configurations.

§1 Application example First, an example of a situation in which the present invention is applied will be described with reference to FIG. The adjustment support system 100 according to the present embodiment includes a work table 50 provided in the work area R, a camera 20 that captures moving image data indicating the operation of the worker executed in the work area R, and an operation indicating the operation of the worker. It includes a motion sensor 21 for measuring data, a line-of-sight sensor 22 for measuring line-of-sight data indicating the line of sight of an operator, and a vital sensor 23 for measuring vital data of an operator. The work area R of this example is an area including the entire production line, but the work area R may be an arbitrary area, for example, an area where a predetermined process is performed. Here, the predetermined process includes, for example, operations such as picking of parts, arrangement of parts, fixing of parts, and packing of products, and more specifically, operations such as screw tightening may be included.

In this example, a case where the first worker A1 and the second worker A2 perform a predetermined operation in the work area R will be described. The first worker A1 can perform operations such as picking, arranging, and fixing the first component, and the second worker A2 can perform operations such as picking, arranging, and fixing the second component. Hereinafter, the first worker A1 and the second worker A2 are collectively referred to as the worker A.

The adjustment support system 100 includes an adjustment support device 10. The adjustment support device 10 calculates a first factor that fluctuates in a time span of a predetermined period or more and a second factor that fluctuates in a time span of less than a predetermined period based on the data related to the worker. Here, the first factor may include, for example, a numerical value representing the proficiency level of the worker regarding a predetermined work, and the second factor may include, for example, a numerical value representing the physical condition of the worker. The predetermined period may be, for example, one hour, one day, or one week, and is arbitrary. Further, the predetermined period for determining the first factor (for example, one week) and the predetermined period for determining the second factor (for example, one day) may be different.

The adjustment support device 10 determines a reference value for the height of the workbench used by the worker based on the first factor, and determines an adjustment value with respect to the reference value based on the second factor. Here, the reference value is a value that hardly fluctuates in the short term, and the adjustment value is a value that may fluctuate during, for example, one day's working hours. In this way, the adjustment support device 10 calculates the reference value of the height of the workbench 50 based on the first factor that fluctuates in a relatively long time span, and is based on the second factor that fluctuates in a relatively short time span. The height adjustment value of the workbench 50 is calculated.

Then, the adjustment support device 10 outputs information regarding the height of the workbench 50 based on the reference value and the adjustment value. The adjustment support device 10 may output information on the height of the workbench 50 to the display unit 10f, and the worker A may adjust the height of the workbench 50 based on the information on the height of the workbench 50. .. When the workbench 50 has a drive unit for height adjustment, the adjustment support device 10 directly outputs information on the height of the workbench 50 to the workbench 50, and the workbench 50 outputs the received information to the information. The height may be changed automatically based on this.

FIG. 2 is a diagram showing an outline of adjusting the height of the workbench 50 by the adjustment support system 100 according to the present embodiment. The figure shows how the first worker A1 tightens the screws using the workbench 50. The left side of the figure shows the workbench 50 having a height of h1, and the right side shows the workbench 50 having a height of h2 (h1 <h2). The height of the workbench 50 is adjusted based on the information regarding the height of the workbench 50 output by the adjustment support device 10.

For example, in the case of screw tightening work, since beginners work while looking at the tip of the screwdriver, if the workbench 50 is low, they may bend down and look into the screw holes, and the higher the workbench 50 is, the better. It may be possible to reduce the degree of fatigue. On the other hand, a skilled person can work without looking at the tip of the driver, and lowering the workbench 50 may allow the work without applying unnecessary force. However, even a skilled person may increase the degree of fatigue due to long-term work, and in that case, the degree of fatigue may be reduced by changing the height of the workbench 50 higher. In these examples, proficiency (beginner or expert) is the first factor that fluctuates over a relatively long time span, and fatigue is a second factor that fluctuates over a relatively short time span. is there.

According to the adjustment support device 10 according to the present embodiment, the work is performed so as to improve the work efficiency in consideration of the first factor that fluctuates in a relatively long time span and the second factor that fluctuates in a relatively short time span. The height of the table 50 can be adjusted. As a result, the height of the workbench 50 is increased in consideration of not only factors that hardly change over a long period of time such as the physical characteristics and skill level of the worker but also factors that change in a relatively short period of time such as the health condition of the worker. It can be adjusted appropriately, and the work efficiency of the worker can be improved.

[Hardware configuration]
FIG. 4 is a diagram showing a physical configuration of the adjustment support device 10 according to the present embodiment. The adjustment support device 10 includes a CPU (Central Processing Unit) 10a corresponding to a calculation unit, a RAM (Random Access Memory) 10b corresponding to a storage unit, a ROM (Read only Memory) 10c corresponding to a storage unit, and a communication unit. It has 10d, an input unit 10e, and a display unit 10f. Each of these configurations is connected to each other via a bus so that data can be transmitted and received. In this example, the case where the adjustment support device 10 is composed of one computer will be described, but the adjustment support device 10 may be realized by combining a plurality of computers. Further, the configuration shown in FIG. 4 is an example, and the adjustment support device 10 may have a configuration other than these, or may not have a part of these configurations.

The CPU 10a is a control unit that controls execution of a program stored in the RAM 10b or ROM 10c, calculates data, and processes data. The CPU 10a is a calculation unit that executes a program (adjustment support program) that determines information regarding the height of the workbench 50. The CPU 10a receives various data from the input unit 10e and the communication unit 10d, displays the calculation result of the data on the display unit 10f, and stores the data in the RAM 10b.

The RAM 10b is a storage unit in which data can be rewritten, and may be composed of, for example, a semiconductor storage element. The RAM 10b may store data such as a program executed by the CPU 10a, image data, moving image data, operation data, line-of-sight data, and vital data. It should be noted that these are examples, and data other than these may be stored in the RAM 10b, or a part of these may not be stored.

The ROM 10c is a storage unit capable of reading data, and may be composed of, for example, a semiconductor storage element. The ROM 10c may store, for example, an adjustment support program or data that is not rewritten.

The communication unit 10d is an interface for connecting the adjustment support device 10 to another device. The communication unit 10d may be connected to a communication network such as the Internet.

The input unit 10e receives data input from the user, and may include, for example, a keyboard and a touch panel.

The display unit 10f visually displays the calculation result by the CPU 10a, and may be configured by, for example, an LCD (Liquid Crystal Display). The display unit 10f may display information regarding the height of the workbench 50.

The adjustment support program may be stored in a storage medium readable by a computer such as RAM 10b or ROM 10c and provided, or may be provided via a communication network connected by the communication unit 10d. In the adjustment support device 10, the CPU 10a executes the adjustment support program to realize various operations described with reference to FIG. It should be noted that these physical configurations are examples and do not necessarily have to be independent configurations. For example, the adjustment support device 10 may include an LSI (Large-Scale Integration) in which the CPU 10a and the RAM 10b or ROM 10c are integrated.

§3 Operation example FIG. 5 is a table showing adjustment values of the height of the workbench 50 referred to by the adjustment support device 10 according to the present embodiment. The table shown in the figure is an example of a table showing the correspondence between the second factor and the adjustment value.

The table of this example includes a second factor including a numerical value indicating the proficiency level of the worker regarding a predetermined work, a numerical value indicating the productivity, and a numerical value indicating the physical condition of the worker, and adjustment of the height of the workbench 50 with respect to the reference value. The correspondence with the value is shown.

In the table of this example, a numerical value indicating the proficiency level of the worker and a numerical value indicating the productivity of a predetermined work are binarized. The numerical value is 0 when the proficiency level or productivity of the worker related to the predetermined work is low, and is 1 when the proficiency level or productivity of the worker related to the predetermined work is high. However, the method of binarization is arbitrary, and a numerical value indicating the proficiency level of the worker and a numerical value indicating productivity related to a predetermined work may be binarized by a method other than the method shown here.

Further, in the table of this example, a numerical value obtained by binarizing a numerical value indicating the physical condition of the worker is illustrated. The numerical value is 0 when the worker is in poor physical condition, and is 1 when the worker is in good physical condition. However, the binarization method is arbitrary, and a numerical value indicating the physical condition of the worker may be binarized by a method other than the method shown here.

In the table of this example, according to the combination of the numerical value indicating the proficiency level and productivity of the worker (binarized numerical value) and the numerical value indicating the physical condition of the worker (binarized numerical value) regarding a predetermined work. , The adjustment value with respect to the reference value of the height of the workbench 50 is illustrated. Specifically, when the numerical value indicating the proficiency level and productivity of the worker regarding the predetermined work is 0 and the numerical value indicating the physical condition of the worker is 0, the adjustment value is "+10 cm" and the predetermined work is related. When the numerical value indicating the proficiency level and productivity of the worker is 0 and the numerical value indicating the physical condition of the worker is 1, the adjustment value is "+5 cm", which indicates the proficiency level and productivity of the worker regarding the predetermined work. When the indicated numerical value is 1 and the numerical value indicating the physical condition of the worker is 0, the adjusted value is "+5 cm or -5 cm", and the numerical value indicating the proficiency level and productivity of the worker regarding the predetermined work is 1. When the numerical value indicating the physical condition of the worker is 1, the adjustment value is "0".

Here, when the numerical value indicating the proficiency level and productivity of the worker regarding the predetermined work is 1 and the numerical value indicating the physical condition of the worker is 0, the adjustment support device 10 depends on the physical condition of the worker. The adjustment value may be selected to be +5 cm or -5 cm. For example, when the near vision of the worker is decreasing, the adjustment support device 10 may determine the adjustment value to be +5 cm.
