  The best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described below with reference to the drawings.

  The component storage position indicating device according to the present embodiment is a device that notifies an operator of a storage position in which a component to be assembled to a product to be assembled and manufactured is stored in accordance with the component mounting order.

  FIG. 1 is a diagram showing functional blocks of the component storage position instruction apparatus according to the present embodiment.

  In FIG. 1, the control unit 10 controls the entire component storage position instruction device. The operation unit 22 receives input of various instructions from the worker. The operation unit 22 includes a mouse, a keyboard, and the like, and accepts selection of a product type such as an electronic device to be assembled and manufactured from an operator, for example. The operation unit 22 includes a switch and a button that can be pressed by the operator such as a foot switch, and receives, for example, an input of a completion notification indicating that the attachment of the component to be attached has been completed.

  The component table storage unit 12 stores a component table as shown in FIG. 2 for each type of product to be assembled and manufactured. In the parts table, a storage position ID for uniquely specifying a storage position of a storage shelf that is a storage unit in which a part to be mounted is stored for each part mounting order, and a product in which the part to be mounted is assembled. Are registered in association with an attachment position ID that uniquely identifies the attachment position. The control unit 10 obtains a part table corresponding to the selected product to be assembled and manufactured from the part table storage unit 12 and refers to the part table to store the parts to be attached according to the part mounting order. The position ID and the attachment position ID of the part to be attached can be specified.

  The take-out position lamp 30L is provided in association with each storage position 30B of the storage shelf 30 as shown in FIG. 3, and lighting control is performed by the control unit 10. The control unit 10 can notify the operator of the storage position 30B where the parts to be picked up are stored by turning on the pick-up position lamp 30L corresponding to the storage position 30B where the parts to be picked up are stored. .

  The take-out position detector 36 detects the storage position of the storage shelf from which the operator has actually taken out the parts. As shown in FIG. 3, the take-out position detection unit 36 includes sensor light projecting units 38 a-1 such as infrared sensors provided on the side of the storage shelf 30 in the column direction and the row direction in association with the component storage positions. 38a-3, 38b-1 to 38b-3 and sensor light receiving units 39a-1 to 39a-3, 39b for receiving light from the sensor light projecting units 38a-1 to 38a-3, 38b-1 to 38b-3. -1 to 39b-3.

  The control unit 10 acquires a light receiving state from each of the sensor light receiving units 39a and 39b, and specifies from which storage position the operator has taken out the component based on the light receiving state.

  When the operator takes out the component, the operator's hand prevents light from the sensor light projecting unit 38 from entering the sensor light receiving unit 39. Therefore, the control unit 10 specifies the sensor light receiving unit 39b as the light receiving state one by one in the column direction and the row direction in which the amount of incident light is equal to or less than a predetermined threshold, and sets the position of the specified sensor light receiving unit 39b. Based on this, the storage position from which the worker has taken out the component is specified.

  For example, when the sensor light receiving unit whose light incident amount is equal to or smaller than a predetermined threshold is the column direction: sensor light receiving unit 39a-2 and the row direction: sensor light receiving unit 39b-2, the control unit 10 may The storage position from which the part is taken out is identified as “B0202”.

  Further, the control unit 10 determines whether or not the storage position where the operator actually took out the part matches the correct storage position of the part to be attached. The operator is notified that the parts taken out are incorrect. The notification unit 20 is configured by a buzzer, for example, and notifies the worker by voice.

  The take-out position detection unit 36 is not limited to the sensor as described above. For example, a line sensor is provided for each line in the column direction and the row direction, and an operator takes out a component based on the incident light amount of the line sensor. The storage position may be specified.

  Alternatively, the movement position of the worker's hand may be photographed with a camera, and the photographed image may be processed to specify the storage position where the worker has taken out the part. Further, the notification unit 20 is not limited to a buzzer, and may notify the worker by displaying a message indicating that a component is incorrect on the screen, for example.

  The attachment position lamp 40L is a lamp for indicating the attachment position of the part to be taken out to the product to be assembled and manufactured. For example, when the product to be assembled and manufactured is a “connector” and the part to be attached is a cable, as shown in FIG. 4, each cable of the connector 50 fixed to the work table 60 via a fixing tool 62 is used. An attachment position lamp 40L is arranged in association with each of the attachment positions P0101 to P0204.

  The attachment position image storage unit 14 stores an image for each attachment position for indicating the attachment position to the product to be assembled and manufactured to the operator in association with the attachment position ID. The attachment position image is, for example, an image as shown in FIG.

  FIG. 5 is an image showing that the attachment position of the part to be taken out is “P0102”. The control unit 10 acquires an attachment image corresponding to the attachment position ID of the part to be attached from the attachment position image storage unit 14 and displays it on the display unit 24.

  The component storage position indicating device configured as described above prevents an error in the mounting position by notifying the operator of the mounting position of the component to be taken out. Furthermore, the component storage position indicating device detects the storage position where the worker actually took out the component, and if the detected storage position is different from the storage position where the component to be taken out is stored, the component storage position indicating device informs the operator. To prevent mistakes in the parts to be taken out.

  FIG. 6 is a flowchart showing a processing flow of the control unit 10 when instructing an operator of a part to be taken out.

  First, the control unit 10 displays a plurality of predetermined models to be assembled on the display unit 24, and causes the operator to select a model to be assembled from the displayed models via the operation unit 22. Thus, the selection of the model to be assembled is accepted (S100).

  Next, the control unit 10 retrieves the component table corresponding to the selected model from the component table storage unit 12, refers to the component table, and first stores the storage position ID of the first component to be extracted according to the extraction order. The attachment position ID is specified (S102).

  Subsequently, the control unit 10 lights the take-out position lamp 30L corresponding to the specified storage position ID, and lights the mounting position lamp 40L corresponding to the specified mounting position ID.

  Here, the control unit 10 may notify the worker of a message by voice so as to take out the part from the storage position where the lamp is lit, or may display the message on the display unit 24. Moreover, the control part 10 may display the image prepared beforehand which shows a mode that an operator takes out components from a storage shelf on the display part 24, in order to make a worker grasp | ascertain a work content easily.

  Further, the control unit 10 takes out the attachment position image corresponding to the attachment position ID from the attachment position image storage unit 14 and displays the image on the display unit 24 (S104).

  Thereafter, the control unit 10 acquires storage position information indicating the storage position from which the operator has actually removed the component from the extraction position detection unit 36 (S106), and the storage position corresponding to the component to be extracted corresponds to the storage position. (S108). If they do not match as a result of the determination, the control unit 10 gives an error notification indicating that the part taken out to the operator is incorrect via the notification unit 20 (S110).

  On the other hand, if the results of the determination in step S108 match, the control unit 10 notifies the operator that the attachment of the taken-out component to the product to be assembled is completed via the operation unit 22 from the operator. Wait until you receive it.

  For example, the operator may notify the completion by turning on the foot switch. Thereafter, when detecting the completion notification (S112), the control unit 10 refers to the component table to determine whether or not the mounting of all the components is completed (S114). The processes in and after step S102 are repeated for the parts to be taken out in this order.

  On the other hand, when all the attachments are completed (the determination result of step S114 is affirmative “Y”), the control unit 10 ends the process.

  As described above, according to the present embodiment, it is possible to prevent an error in the mounting position by notifying the worker of the mounting position of the component to be taken out.

  Furthermore, according to the present embodiment, when the worker actually detects the storage position where the part is taken out and the detected storage position is different from the storage position where the part to be taken out is stored, the operator is notified of that fact. By notifying the error, it is possible to prevent an error of a part to be taken out.

  In the present invention, when the storage position corresponding to the part to be taken out differs from the detected storage position, the operator is notified that the storage position from which the part has been taken out is incorrect. When manufacturing one product by assembling, the necessary parts can be taken out from the storage shelf more reliably, so it is necessary to assemble the product at the position by taking out multiple types of parts from the storage part and assembling them sequentially Further, the present invention is suitable for a component storage instruction device, a component storage position instruction method, and the like that indicate a storage position in the storage unit in which each storage component is stored when taking out each component from the storage unit.
