  The microphone 25 detects command input by the voice of the worker 2. The speaker 26 outputs a warning sound, work support information by voice, and the like to the worker 2.

  The controller 27 is an application specific integrated circuit (ASIC), a microcomputer that executes a control program, and the like, and performs data processing for assisting adjustment work.

  Here, the wearable device 11 is an integrated device of a head mount type, but may be a device combining a wearable computer and a head mounted display, for example.

  When the controller 27 detects the voice command of the worker 2 using the microphone 25, the controller 27 transmits a request based on the voice command to the work target 3. At that time, the controller 27 may transmit the request directly to the work object 3 using the short-range wireless communication device 21, or the work object via the management server 12 using the network interface 22. 3 may be transmitted.

  Further, when the controller 27 detects an imaging command (voice command) of the worker 2 using the microphone 25, the controller 27 causes the imaging device 24 to execute an imaging operation and acquires image data of the captured image from the imaging device 24.

  In particular, the controller 27 (a) acquires the identification information of the work object 3 from the work object 3 by the short-range wireless communication device 21, and (b) manages the acquired identification information of the work object 3 by the network interface 22. Send to server 12. When the management server 12 receives the identification information of the work object 3, the management server 12 associates the work object 3 with the wearable device 11 (that is, the worker 2).

  FIG. 3 is a diagram illustrating an example of the machine information 101 displayed in the field of view of the worker 2 by the wearable device 11 in the system illustrated in FIG. 1. As shown in FIG. 3, when the identification information of the work object 3 is acquired, the machine information 101 of the work object 3 corresponding to the identification information is acquired from the management server 12 and displayed.

  First, the controller 27 captures an image of the test print with the image pickup device 24, transmits the captured image data of the test print to the management server 12, and then sets the setting value (new setting value) automatically adjusted based on the captured image data. ) And the image data of the preview image of the test print based on the new set value, and the display device 25 displays the new set value and the preview image on the worker 2. That is, the worker 2 operates the work object 3 to print the test printed material 111 with the setting value before the setting value changing work.

  FIG. 4 is a diagram illustrating an example of a test print 111 taken by the wearable device 11 within the field of view of the worker 2 in the system shown in FIG. The worker 2 operates the work target 3 to print the test print 111 with the current set value.

  The controller 27 also displays (a) a set value of the work object 3 and a preview image of a test print based on the set value on the display device 23 to the worker 2, and (a) a set value by the microphone 25. When the change command (here, the voice command of the worker 2) is detected, a new set value designated by the set value change command and a preview image of the test print based on the new set value are displayed on the display device 23 by the worker 2 (C) When the set value confirmation command (here, the voice command of the worker 2) is detected by the microphone 25, the new set value at the time point specified by the set value confirmation command is directly Alternatively, the work object 3 is set via the management server 12.

  When the new set value is directly set to the work object 3, the new set value is transmitted to the work object 3 by the short-range wireless communication device 21. Further, when the new setting value is set in the work object 3 via the management server 12, the new setting value is transmitted to the management server 12 through the network interface 22, and then the work target is set by the management server 12. Sent to object 3.

  FIG. 5 is a diagram illustrating an example of setting values after automatic adjustment and a preview image of a test printed matter displayed in the field of view of the worker 2 by the wearable device 11 in the system shown in FIG. 1. FIG. 6 is a diagram illustrating an example of setting values after manual adjustment displayed in the field of view of the worker 2 by the wearable device 11 and a preview image of a test print in the system illustrated in FIG. 1.

  For example, a preview image 121 after automatic adjustment as shown in FIG. 5 and a set value 122 after automatic adjustment are displayed, and when a setting value change command is detected thereafter, a preview after manual adjustment as shown in FIG. An image 131 and a set value 132 after manual adjustment are displayed.

  During automatic adjustment and manual adjustment, the worker 2 does not operate the work object 3. That is, the test printed matter is printed only once before automatic adjustment, and is not printed during automatic adjustment and manual adjustment.

  Further, the controller 27 receives other work support information (for example, text and images indicating work procedures) from the management server 12 and displays them on the display device 25 for the worker 2.

  FIG. 7 is a block diagram showing the configuration of the management server 12 in FIG.

  The management server 12 is a server computer having a network communication function in which an operating system, a server program, and the like are installed, for example.

  The management server 12 includes a communication device 31, a storage device 32, and an arithmetic processing device 33.

  The communication device 31 is a device that is connected to a network and performs data communication with other devices (work object 3, wearable device 11 and the like) via the network using a predetermined communication protocol. As the communication device 31, a network interface, a modem, or the like is used.

  The storage device 32 is a device capable of storing various data and programs. As the storage device 32, a nonvolatile mass storage medium such as a nonvolatile memory or a hard disk drive is used.

  The arithmetic processing unit 33 is a computer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and loads a program from the storage device 32, the ROM, etc. to the RAM. When the program is executed by the CPU, it operates as various processing units. Here, the arithmetic processing unit 33 operates as an operating system (not shown), a current set value collection unit 51, a work support information providing unit 52, a set value adjustment unit 53, and the like.

  The current setting value collection unit 51 receives the identification information of the work object 3 from the wearable device 11 via the network using the communication device 31, and obtains the current setting value from the work object 3 of the received identification information. get.

  The work support information providing unit 52 transmits, to the wearable device 11, the set value of the work target 3 and a preview image of the test print based on the set value to the wearable device 11 as work support information.

  The set value adjustment unit 53 sets the new set value at the time point designated by the set value confirmation command to the work object 3.

  The set value adjustment unit 53 receives captured image data from the wearable device 11 and automatically adjusts the set value of the work target 3 based on the captured image data.

  That is, the set value adjustment unit 53 identifies the amount of deviation from the reference value of the adjustment item based on the captured image data, and automatically adjusts the set value of the work target 3 so that the amount of deviation decreases. The work support information providing unit 52 generates a preview image based on the captured image data and the set value after automatic adjustment, transmits the image data of the preview image to the wearable device 11, and displays the preview image on the wearable device 11. Let

  Here, the predetermined adjustment item is a printing position or a printing color.

  The printing position is the position of the test pattern in the printing paper. When the predetermined adjustment item is a printing position, examples of the setting item include a conveyance speed of printing paper, a margin from a synchronization signal (BD signal) of an LSU (Laser Scanning Unit), and the like. When the predetermined adjustment item is the print position, a shift in the position of the test pattern in the main scanning direction and the sub-scanning direction is detected. Note that the amount of misalignment is determined by a ratio with respect to the size of the prescribed printing paper.

  The print color is the color of the test pattern on the printing paper (for example, RGB color). When the predetermined adjustment item is a print color, the setting item includes, for example, the density of each toner color. When the predetermined adjustment item is a print color, a color shift (for example, a color difference from the reference color) for the test pattern is detected.

  Next, the operation of the adjustment work support system will be described. FIG. 6 is a flowchart for explaining the operation of the management server 12 in the adjustment work support system shown in FIG.

  First, the worker 2 wears the wearable device 11 and approaches the work target 3. As a result, the wearable device 11 acquires identification information from the work object 3 by the short-range wireless communication device 21 and transmits the identification information to the management server 12 by the network interface 22. When the management server 12 receives the identification information, the management server 12 identifies the electronic device (work object 3) with the identification information, and acquires the current setting value from the identified work object 3.

  The worker 2 operates the work target 3 to print the test print with the set value at the current time, and images the test print with the wearable device 11. The wearable device 11 transmits the image data of the captured image to the management server 12. The management server 12 receives the image data and performs automatic adjustment of the setting value based on the image data. In the automatic adjustment, a new set value is specified, but is not applied to the work target 3 at this time.

  After the automatic adjustment is completed, the management server 12 determines the test printed material when the new setting value obtained by the automatic adjustment is applied based on the captured image data of the test printed material and the new setting value obtained by the automatic adjustment. A preview image is generated, and the new setting value and the image data of the preview image are transmitted to the wearable device 11.

  For example, when the adjustment item is the print position, the position of the test pattern in the printing paper is specified based on the captured image data, and the position of the test pattern is changed according to the new setting value obtained by automatic adjustment. As a result, a preview image of the test printed matter when the new set value is applied is generated.

  The wearable device 11 receives the new setting value and the preview image from the management server 12 and displays them on the worker 2 on the display device 23 as shown in FIG. 5, for example.

  Thereafter, when the worker 2 inputs a setting value change command for designating a new setting value to the wearable device 11 by voice, the new setting value is transmitted from the wearable device 11 to the management server 12.

  When the new setting value is received from the wearable device 11, the management server 12 generates a new preview image based on the captured image data and the newly received new setting value, and the new setting value and the image data of the preview image. Is transmitted to the wearable device 11.

  When the wearable device 11 newly receives a new setting value and a preview image from the management server 12, for example, as shown in FIG.

  Such manual adjustment can be performed a plurality of times.

  When the worker 2 determines that the current set value is appropriate based on the preview image, the worker 2 inputs a set value change command for confirming the new set value to the wearable device 11 by voice. As a result, the current new set value is set in the work object 3.

  As described above, according to the first embodiment, the wearable device 11 displays (a) the set value of the work object 3 and the preview image of the test print based on the set value for the worker 2 on the display device. (A) When a set value change command is detected by the microphone, a new set value designated by the set value change command and a preview image of a test print based on the new set value are displayed to the worker 2 using the display device. (C) When the set value confirmation command is detected by the microphone, the new set value at the time point specified by the set value confirmation command is set to the work object 3 directly or via the management server 12. The management server 12 transmits the setting value of the work target 3 and the preview image of the test print based on the setting value to the wearable device 11.

  Thereby, the frequency | count of printing a test printed matter decreases, and the burden of the adjustment operation | work of the worker 2 with which the wearable device 11 was mounted | worn is reduced.

Embodiment 2. FIG.

  In the second embodiment, the management server 12 measures the time required for the setting work described above, specifies the skill level of the worker 2 based on the required time, and provides work support information corresponding to the skill level as a wearable device. 11 to send. The wearable device 11 receives the work support information and displays it to the worker 2.

  Thereby, for example, the minimum necessary work procedure is presented to the worker 2 with high skill level, and a more detailed work procedure is presented to the worker 2 with low skill level.

  In addition, since the other structure and operation | movement of the adjustment work assistance system which concern on Embodiment 2 are the same as that of Embodiment 1, the description is abbreviate | omitted.

Embodiment 3 FIG.

  In the third embodiment, the management server 12 generates a history of new setting values set in the electronic device of the work target 3 for each type of the work target (electronic device) and each worker, and adjusts the target of the adjustment work. The set value is automatically adjusted based on the type of the work object 3 and the history corresponding to the worker 2.

  Note that other configurations and operations of the adjustment work support system according to Embodiment 3 are the same as those in Embodiment 1 or Embodiment 2, and thus description thereof is omitted.

  Various changes and modifications to the above-described embodiment will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the subject matter and without diminishing its intended advantages. That is, such changes and modifications are intended to be included within the scope of the claims.
