An aspect of the present disclosure relates to a work assistance system.
A work assistance system is known which assists workers in operation, for example, in a factory using augmented reality (AR). For example, Patent Literature 1 discloses a work assistance system that displays additional information such as work explanatory information on a work target through an image display unit in the shape of eyeglasses disposed in front of the worker's eyes to cover the worker's field of vision.
Patent Literature 1: Japanese Unexamined Patent Publication No. 2016-208331
Such a system can provide workers with various information. However, there is a room for improvement in various points in order to improve the work efficiency of workers.
An aspect of the present disclosure therefore is to provide a work assistance system that can improve the work efficiency of workers.
A work assistance system according to an aspect of the present disclosure assists a worker working in a factory equipped with a plurality of processing apparatuses. The work assistance system includes a display unit having portability and configured to display information provided to the worker, an imaging unit having portability and configured to capture an image of the processing apparatus, a display controller configured to control a content of information displayed on the display unit, and an identifying unit configured to identify from which direction the processing apparatus is captured by the imaging unit, based on data captured by the imaging unit. When the direction identified by the identifying unit is a predetermined direction, the display controller causes the display unit to display an adjustment screen for adjusting an operation parameter of the processing apparatus captured by the imaging unit.
In the work assistance system having this configuration, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to adjust the operation of one processing apparatus, the worker would view the processing apparatus from a particular one direction. In this configuration, information to be provided to the worker (the adjustment screen for the operation parameter) can be provided at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
In the work assistance system according to an aspect of the present disclosure, the display unit may display a real space in the factory and the adjustment screen so as to overlap each other. In the work assistance system having this configuration, the processing apparatus and the adjustment screen for adjusting an operation parameter in the processing apparatus are displayed in an overlapped state. As a result, the worker can intuitively understand for which apparatus the parameter is to be adjusted on the adjustment screen appearing on the display unit.
The work assistance system according to an aspect of the present disclosure may further include an input unit configured to input the operation parameter in the adjustment screen and a communication unit configured to transmit the operation parameter input through the input unit to the processing apparatus. In the work assistance system having this configuration, the operation parameter of the processing apparatus can be changed through the display unit having portability, the input unit, and the communication unit. This configuration enables the worker to adjust the processing apparatus more efficiently.
In the work assistance system according to an aspect of the present disclosure, the display controller may allow the adjustment screen to be displayed only when the direction identified by the identifying unit is a predetermined direction. The work assistance system having this configuration prevents the adjustment screen from appearing on the display unit with easy operation and therefore prevents the setting of the processing apparatus from being changed carelessly.
In the work assistance system according to an aspect of the present disclosure, when the direction identified by the identifying unit is a predetermined direction, the display controller may cause the display unit to display the adjustment screen corresponding to the processing apparatus captured by the imaging unit, and when the direction identified by the identifying unit is a direction other than the predetermined direction, the display controller may cause the display unit to display an operating status display screen displaying an operating status of the processing apparatus captured by the imaging unit. In the work assistance system having this configuration, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to adjust the operation of one processing apparatus, the worker would view the processing apparatus from a particular one direction, and in a state in which the worker wishes to check the state of one processing apparatus, the worker would view the processing apparatus from a different direction. In this configuration, information to be provided to the worker (the adjustment screen for the operation parameter or the operating status display screen) can be switched at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
In the work assistance system according to an aspect of the present disclosure, when the direction identified by the identifying unit is a predetermined direction and only some of parts included in the processing apparatus are captured by the imaging unit, the display controller may display the adjustment screen only corresponding to the part captured by the imaging unit on the display unit. In the work assistance system having this configuration, a screen appears that enables adjustment of only the operation parameter of the part assumed to be viewed by the worker. As a result, only the minimum information required by the worker is provided, and adjustment of an unintended part can be prevented.
In the work assistance system according to an aspect of the present disclosure, the processing apparatus may be a combination weighing apparatus configured to combination-weigh an article externally charged and supply the combination-weighed article to another processing apparatus disposed on a downstream side. When the direction identified by the identifying unit is an upper direction (above) of the combination weighing apparatus, the display controller may allow the adjustment screen of the combination weighing apparatus to be displayed. In the work assistance system having this configuration, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to adjust the operation of one combination weighing apparatus, the worker would get on a base and view the combination weighing apparatus from the upper direction. In the work assistance system having this configuration, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to check the state of one combination weighing apparatus, the worker would view so as to look up the one combination weighing apparatus from the lower direction. In this configuration, information to be provided to the worker (the adjustment screen for the operation parameter of the combination weighing apparatus or the operating status display screen of the combination weighing apparatus) can be switched at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
According to an aspect of the present disclosure, the work efficiency of workers can be improved.
A preferred embodiment according to an aspect of the present disclosure will be described in detail below with reference to the accompanying drawings. In a description of the drawings, the same or corresponding elements are denoted by the same reference signs and an overlapping description will be omitted.
A work assistance system 1 in the present embodiment is a system that assists workers who work in a factory equipped with a plurality of processing apparatuses. In the present embodiment, the work assistance system 1 used in a factory equipped with a production line 30 including a conveyance apparatus 35, a combination weighing apparatus 40, a bag-making and packing apparatus 70, a seal inspection apparatus 75, an X-ray inspection apparatus 80, a metal detector 85, a weight checking apparatus 90, and a case packing apparatus 95 as processing apparatuses as illustrated in
The conveyance apparatus 35 is an apparatus that conveys an article A (see
As illustrated in
The display unit 11 displays information provided to the worker. The display unit 11 displays (superimposes) the real space in the factory and information provided to the worker so as to overlap each other. Superimposition on the display unit 11 is implemented, for example, by configuring the display unit 11 with a half mirror or by projecting an image captured by the imaging unit 15 onto the display unit 11.
The imaging unit 15 captures an image of the real space in a factory. The imaging unit 15 is provided such that the real space viewed by the worker wearing the HMD 10 generally matches the real space captured by the imaging unit 15. That is, the imaging unit 15 is a vision synchronous camera that captures a front view image in the eye direction of the worker. The imaging unit 15 causes the display unit 11 to display the captured data. The imaging unit 15 also transmits the captured data to the management server 20.
The input unit 16 includes keys to select up, down, left, and right and a key to confirm an entry. The worker can operate the input unit 16 to select a menu appearing on the display unit 11 or confirm a menu.
The communication unit 17 is an interface for exchanging data with the management server 20. Communication with the management server 20 may be wireless or wired.
The management server 20 is configured as a computer system including a central processing unit (CPU), a main memory such as a random access memory (RAM) and a read only memory (ROM), an auxiliary storage such as a hard disk and a flash memory, an input unit such as a keyboard and a mouse, and an output unit such as a display screen. The functions of an identifying unit 22 and a display controller 23 described in detail in the subsequent sections are executed under the control of the CPU by loading predetermined computer software into hardware such as the CPU and the main memory.
The management server 20 is connected to communicate with each of the conveyance apparatus 35, the combination weighing apparatus 40, the bag-making and packing apparatus 70, the seal inspection apparatus 75, the X-ray inspection apparatus 80, the metal detector 85, the weight checking apparatus 90, and the case packing apparatus 95 through a communication unit 21. The management server 20 and each processing apparatus may be connected wirelessly or may be connected by wire. The management server 20 can control the operation of the processing apparatuses included in the production line 30. The management server 20 is also connected to communicate with the HMD 10 through the communication unit 21.
The identifying unit 22 identifies from which direction one processing apparatus is captured by the imaging unit 15, based on data on the one processing apparatus captured by the imaging unit 15. In the present embodiment, from which direction “up”, “down”, “left”, or “right” one processing apparatus is captured by the imaging unit 15 is identified. The capturing direction may be identified by matching the captured image with an image stored in advance or may be identified using information such as position, altitude (height), and direction, if a sensor capable of acquiring such information is installed in the HMD 10.
The display controller 23 controls the content of information appearing on the display unit 11 of the HMD 10. When the identifying unit 22 identifies that the image of one processing apparatus captured by the imaging unit 15 is captured from a predetermined direction, the display controller 23 causes the display unit 11 to display an adjustment screen for adjusting an operation parameter of the one processing apparatus. When the identifying unit 22 identifies that the image of one processing apparatus captured by the imaging unit 15 is captured from the upper direction (above), the display controller 23 in the present embodiment causes the display unit 11 to display an adjustment screen 12B (see
For example, when the identifying unit 22 identifies that the target captured by the imaging unit 15 is the combination weighing apparatus 40 and its image is captured from the upper direction of the combination weighing apparatus 40, the display controller 23 causes the display unit 11 to display the adjustment screen 12B (see
The combination weighing apparatus 40 which is one processing apparatus in the production line 30 will now be described in detail, and the timing at which the operating status display screen 12A and the adjustment screen 12B for the combination weighing apparatus 40 are distributed from the work assistance system 1 to the HMD 10 will be described.
As illustrated in
The input chute 42 is arranged below a conveyance end of the conveyance apparatus 35. The input chute 42 is a tubular member having an inner hollow portion with openings above and below. The article A dropping from the conveyance end of the conveyance apparatus 35 is charged into the inner hollow portion of the input chute 42. The article A dropped into the inner hollow portion is discharged to the distributing table 43 through the opening below.
The distributing table 43 is disposed below the input chute 42. The distributing table 43 has a conical conveyance surface 43a expanding downward. The distributing table 43 rotates the conveyance surface 43a to convey the article A discharged from the input chute 42 to the apex portion of the conveyance surface 43a uniformly toward the outer edge of the conveyance surface 43a.
A driver 55 rotates the distributing table 43 about the center portion of the distributing table 43. An example of the driver 55 is a motor. The driver 55 intermittently rotates the distributing table 43. That is, the distributing table 43 repeats rotating and stopping.
A plurality of radial feeders 44 are disposed radially along the outer edge of the conveyance surface 43a that is a surface of the distributing table 43. Each radial feeder 44 has a supply trough 44a extending from below the outer edge of the conveyance surface 43a toward the outer edge. Each radial feeder 44 vibrates the supply trough 44a to convey the article A discharged from the outer edge of the conveyance surface 43a toward the front end portion of the supply trough 44a.
Each pool hopper 45 is disposed below the front end portion of the supply trough 44a of each radial feeder 44. At the bottom portion of each pool hopper 45, a gate 45a that can be opened and closed is provided. Each pool hopper 45 temporarily stores the article A discharged from the front end portion of the corresponding supply trough 44a with the gate 45a closed and discharges the temporarily stored article A downward when the gate 45a is opened.
Each weighing hopper 46 is disposed below the gate 45a of each pool hopper 45. At the bottom portion of each weighing hopper 46, a gate 46a and a gate 46b that can be opened and closed are provided. Each weighing hopper 46 temporarily stores the article A discharged from the corresponding pool hopper 45 with the gate 46a and the gate 46b closed and discharges the temporarily stored article A downward when the gate 46a or the gate 46b is opened.
Each booster hopper 47 is disposed below the gate 46a of the corresponding weighing hopper 46. At the bottom portion of each booster hopper 47, a gate 47a that can be opened and closed is provided. Each booster hopper 47 temporarily stores the article A discharged from the gate 46a side of the corresponding weighing hopper 46 with the gate 47a closed and discharges the temporarily stored article A downward when the gate 47a is opened.
The collecting chute 48 is formed in a tubular shape having an inner surface 48a shaped in a truncated cone tapered downward. The collecting chute 48 is disposed such that the inner surface 48a is positioned below all of the weighing hoppers 46 and all of the booster hoppers 47. The collecting chute 48 receives the article A discharged from the gate 46b side of each weighing hopper 46 and the article A discharged from each booster hopper 47 on the inner surface 48a and discharges the article A downward.
The timing hopper 49 is disposed below the collecting chute 48. At the bottom portion of the timing hopper 49, a gate 49a that can be opened and closed is provided. The timing hopper 49 temporarily stores the article A discharged from the collecting chute 48 with the gate 49a closed and discharges the temporarily stored article A to the bag-making and packing apparatus 70 when the gate 49a is opened.
The input chute 42, the distributing table 43, a plurality of radial feeders 44, a plurality of pool hoppers 45, and a plurality of weighing hoppers 46 are supported directly or indirectly on a case 53. A plurality of booster hoppers 47, the collecting chute 48, and the timing hopper 49 are supported directly or indirectly on a frame 52.
The weighing unit 51 is disposed in the case 53 supported by the frame 52. The weighing unit 51 has a plurality of load cells 51a. Each load cell 51a supports the corresponding weighing hopper 46. The weighing unit 51 measures a weight value corresponding to the mass of the article A when the article A is temporarily stored in each weighing hopper 46.
The controller 60 is disposed in the case 53. The controller 60 is a device controlling various operations in the combination weighing apparatus 40 and is a signal processing apparatus including a CPU, a ROM, and a RAM. The controller 60 controls the operation of each unit of the combination weighing apparatus 40, such as conveyance operation of the distributing table 43 and each radial feeder 44, the opening/closing operation of the gate 45a of each pool hopper 45, the opening/closing operation of the gate 46a and the gate 46b of each weighing hopper 46, the opening/closing operation of the gate 47a of each booster hopper 47, and the gate 49a of each timing hopper 49.
The controller 60 selects a combination of weight values from among a plurality of weight values measured by the weighing unit 51 and associated with a plurality of weighing hoppers 46 and/or booster hoppers 47 such that the total value attains a target weight value. Specifically, the controller 60 selects a combination of weight values from among a plurality of weight values output by the weighing unit 51 such that the total value falls within a predetermined range with a target weight value as a lower limit value. The controller 60 then allows the weighing hopper 46 and/or the booster hopper 47 corresponding to the combination to discharge the article A.

As illustrated in
The imaging unit 15 transmits data of the combination weighing apparatus 40 captured from below the base 65 to the management server 20. The identifying unit 22 identifies from which direction the combination weighing apparatus 40 is captured by the imaging unit 15, based on the captured data transmitted from the imaging unit 15. In the present embodiment, from which direction “up”, “down”, “left”, or “right” the combination weighing apparatus 40 is captured by the imaging unit 15 is identified. In this case, the identifying unit 22 identifies that the combination weighing apparatus 40 is captured by the imaging unit 15 from the lower direction.
Next, for example, when the identifying unit 22 identifies that data captured by the imaging unit 15 is captured from, for example, the lower direction other than the upper direction of the combination weighing apparatus 40, the display controller 23 causes the display unit 11 to display the operating status display screen 12A (see
In the operating status display screen 12A, for example, the name of a commodity processed by the combination weighing apparatus 40, the processing capability, the combination target value, the number of heads (hoppers) for realizing the combination target value, and the respective intensity and time of the supply troughs 44a are displayed. The amount of information displayed at a time on the display unit 11 is defined. The worker can operate the keys for selecting up, down, left, and down in the input unit 16 to scroll the information appearing on the display unit 11.
Next, a case where the worker wearing the MID 10 climbs on the base 65 and views the combination weighing apparatus 40 from the upper direction as illustrated in
The imaging unit 15 transmits data of the combination weighing apparatus 40 captured from the upper direction to the management server 20. The identifying unit 22 identifies from which direction the combination weighing apparatus 40 is captured by the imaging unit 15, based on the data transmitted from the imaging unit 15. Here, the identifying unit 22 identifies that the combination weighing apparatus 40 is captured by the imaging unit 15 from the upper direction.
Next, when the identifying unit 22 identifies that data captured by the imaging unit 15 is captured from the upper direction of the combination weighing apparatus 40, the display controller 23 causes the display unit 11 to display the adjustment screen 12B (see
In the adjustment screen 12B, for example, the name of a commodity processed by the combination weighing apparatus 40, the weight value for each weighing hopper 46 (for example, the weight value at present), and an adjuster for each operation parameter in the combination weighing apparatus 40 are displayed. Examples of the weight value for each weighing hopper 46 include the weight value at present and the most recent average weight value. The most recent average weight value may be the most recent average weight value per predetermined time or may be the most recent average weight value per predetermined number of times. That is, the value displayed in the vicinity of this weighing hopper 46 may be any value that is related to the weight value measured in the weighing hopper 46.
Examples of the adjuster for each operation parameter include an intensity adjuster 13A for adjusting the intensity for each supply trough of the combination weighing apparatus 40 and a time adjuster 13B for adjusting the vibration time for each supply trough. The intensity adjuster 13A includes a numerical value display indicating the setting intensity and a slider for adjusting the setting intensity. The worker adjusts the setting intensity by moving the slider through operation of the left/right keys in the input unit 16. Similarly, the time adjuster 13B includes a numerical value display indicating the setting time and a slider for adjusting the setting time. The worker adjusts the setting time by moving the slider through operation of the left/right keys in the input unit 16. The worker can adjust the intensity and/or the vibration time for each supply trough while looking at the weight value for each weighing hopper 46 displayed on the display unit 11, thereby setting the intensity and/or the vibration time as more appropriate.
When the operation parameter in one processing apparatus is adjusted in the adjustment screen 12B, the adjusted operation parameter is transmitted to the management server 20. The communication unit 21 transmits the adjusted parameter to the one processing apparatus. The operation of the one processing apparatus receiving the adjusted parameter is controlled by the adjusted parameter. In the present embodiment, when the setting intensity or the setting time is adjusted in the adjustment screen 12B, the adjusted setting intensity or setting time is transmitted to the management server 20 through the communication unit 17. The adjusted setting intensity or setting time is transmitted to the combination weighing apparatus 40 through the communication unit 21. The controller 60 of the combination weighing apparatus 40 receiving the adjusted setting intensity or setting time controls the supply trough 44a with the adjusted setting intensity or setting time.
The parts whose operation parameters can be adjusted in the combination weighing apparatus 40 include, for example, the supply troughs 44a, the distributing table 43, and the gates 46a, 47a, and 49a of the hoppers 46, 47, and 49. The same part may include a plurality of parts, as is the case with the above-noted supply trough 44a. When the adjustment screen 12B as described above is displayed, the display controller 23 causes the display unit 11 to display the adjustment screen 12B of only the part captured by the imaging unit 15.
For example, as illustrated in
The matching of the part captured by the imaging unit 15 with the adjustment screen 12B to be displayed on the display unit 11 is implemented, for example, by providing an identifier 9 on the part. For example, the identifier 9 is a two-dimensional code in which information for identifying each part is embedded. The display controller 23 can identify which part in one processing apparatus is captured by the imaging unit 15, that is, which part in one processing apparatus is displayed on the display unit 11, based on the identifier 9 captured by the imaging unit 15. The display controller 23 displays only the adjustment screen 12B corresponding to the identified part on the display unit 11. The matching with the adjustment screen 12B to be displayed on the display unit 11 can be implemented by a method other than using the identifier 9. For example, the image captured by the imaging unit 15 may be analyzed, or when the HMD 10 is equipped with a sensor capable of acquiring the position, altitude (height), direction, etc., such information may be used.
The operation effect of the work assistance system 1 in the foregoing embodiment is described. In the work assistance system 1 in the foregoing embodiment, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to adjust the operation of one processing apparatus, the worker would view the processing apparatus from the upper direction (particular one direction). In this configuration, information to be provided to the worker (the adjustment screen 12B for the operation parameter of the processing apparatus) can be provided at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
In the foregoing embodiment, the display unit 11 displays the real space in a factory and the adjustment screen 12B so as to overlap each other. In this configuration, the processing apparatus and the adjustment screen 12B for adjusting the operation parameter in the processing apparatus are displayed in an overlapped state. As a result, the worker can intuitively understand for which apparatus the parameter is to be adjusted on the adjustment screen 12B appearing on the display unit 11.
In the foregoing embodiment, the operation parameter of a processing apparatus can be changed by adjusting the operation parameter in the adjustment screen 12B appearing on the portable HMD 10. This configuration enables the worker to adjust the processing apparatus more efficiently.
In the foregoing embodiment, the display controller 23 allows the adjustment screen 12B to be displayed only when the direction identified by the identifying unit 22 is the upper direction (predetermined direction). This configuration prevents the adjustment screen 12B from appearing on the display unit 11 with easy operation and therefore prevents the setting of the processing apparatus from being changed carelessly.
In the foregoing embodiment, information suitable for a state is provided to the worker, based on the assumption that in a state in which the worker wishes to check the state of one processing apparatus, the worker would view the processing apparatus from a direction different from the upper direction. In this configuration, information to be provided to the worker (the adjustment screen 12B or the operating status display screen 12A) can be switched at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
In the foregoing embodiment, when only some of the parts included in the processing apparatus are captured by the imaging unit 15, the display controller 23 displays only the adjustment screen 12B for adjusting the operation parameter for the part captured by the imaging unit 15 on the display unit 11. In this configuration, only the adjustment screen 12B for adjusting the operation parameter of the part assumed to be viewed by the worker is displayed. As a result, only the minimum information required by the worker is provided, and adjustment of an unintended part can be prevented.
In the foregoing embodiment, when the direction identified by the identifying unit 22 is the upper direction of the combination weighing apparatus 40, the display controller 23 allows the adjustment screen 12B of the combination weighing apparatus 40 to be displayed. In this configuration, information suitable for a state is provided to the worker based on the assumption that in a state in which the worker wishes to adjust the operation of one combination weighing apparatus 40, the worker would go onto the base 65 and view the combination weighing apparatus 40 from the upper direction, and in a state in which the worker wishes to check the state of one combination weighing apparatus 40, the worker would view so as to look up the one combination weighing apparatus 40 from below the base 65. In this configuration, information to be provided to the worker (the adjustment screen 12B or the operating status display screen 12A) can be switched at an appropriate timing based on the state of the worker. As a result, the work efficiency of the worker can be improved.
Although an embodiment has been described above, an aspect of the present disclosure is not limited to the foregoing embodiment and is susceptible to various modifications without departing from the spirit of the disclosure.
In the foregoing embodiment, a portable HMD 10 in the shape of eyeglasses is employed as an apparatus including the display unit 11 and the imaging unit 15. However, for example, a tablet PC 110 including a display unit 111 and an imaging unit 115 as illustrated in
On the display unit 111 illustrated in
In the foregoing embodiment, the adjusted operation parameter is transmitted to each processing apparatus through the management server 20. However, the adjusted operation parameter may be directly transmitted to each processing apparatus through the communication unit 17 included in the HMD 10.
In the foregoing embodiment or modification, the operating status display screen 12A and the adjustment screen 12B related to the combination weighing apparatus 40 are displayed on the display unit 11. However, an operating status display screen and an adjustment screen related to a processing apparatus other than the combination weighing apparatus 40, specifically, the conveyance apparatus 35, the bag-making and packing apparatus 70, the seal inspection apparatus 75, the X-ray inspection apparatus 80, the metal detector 85, the weight checking apparatus 90, and the case packing apparatus 95, may be displayed on the display unit 11. Also in this case, similarly, the display controller 23 determines from which direction the processing apparatus captured by the imaging unit 15, 115 is captured and, if the direction is a predetermined direction, causes the display unit 11 to display an adjustment screen related to the apparatus, and if the direction is a direction other than the predetermined direction, causes the display unit 11 to display an operating status display screen related to the apparatus.
In the foregoing embodiment or modification, when it is determined that data of the combination weighing apparatus 40 captured by the imaging unit 15 is captured from the upper direction (predetermined direction) by the imaging unit 15, the adjustment screen 12B is displayed on the display unit 11. However, for example, the lateral direction (side) or the lower direction (below) other than the upper direction may be set as a predetermined direction. However, based on a particular situation in which the combination weighing apparatus 40 is often installed on the base 65 and the operation for adjusting the combination weighing apparatus 40 is usually done on the base, it is effective to set the upper direction as a predetermined direction in that the adjustment screen 12B for the operation parameter can be provided at an appropriate timing based on the state of the worker.
