  However, such a cell worktable control system has the following problems. That is, a layout pattern such as the number, size, arrangement and the like of the parts box of the cell work table is determined in advance, and this is allowed especially when it is necessary to increase the number of parts boxes (that is, the types of parts). When changing to a cell workbench, it is necessary to rewrite the control program one by one so that the control device to be controlled matches the changed layout pattern. In particular, recently, there has been a demand for production in a small variety of products, and the products to be manufactured often change frequently, and only one cell work table having the same layout pattern can meet the demand for production in a small variety. There have also been cases where this is not possible.

  Another problem is that the operator actually assembles the components on the workbench after taking out the components from the component box, and this causes a problem that an assembly error of the components occurs. Conventionally, in order to correct such an assembly error, a monitor has been installed, and monitor teaching is also performed in which an operator is instructed of a component assembly position by an image. However, if the worker performs the same work regularly, the worker starts assembling work without looking at the monitor, which causes an assembling error again.

To solve the problems of the prior art, the present invention provides a cell workbench control system that can respond quickly to changes in the layout pattern including a number of changes in the parts box provided in the cell workbench This is the first problem.

The present invention is directed to a second object to provide a cell workbench control system which can effectively prevent the parts assembling error of the worker.

  According to the cell worktable control system configured as described above, a plurality of component boxes are arranged on the cell worktable based on a predetermined layout pattern, and a notification device such as a notification lamp or a liquid crystal display device is provided in each of the component boxes. It has been. Then, based on the acquisition order of the parts sent from the cell worktable control device, the notification device provided in the component box containing the corresponding components sequentially notifies (lights up, etc.), thereby giving the operator a predetermined This suggests the order of assembling the parts when producing the product (including intermediate parts).

  Here, the cell work table control apparatus stores a plurality of cell work table layout patterns in the layout storage means. When the cell work table layout pattern is changed, the selection unit selects the corresponding layout pattern from the plurality of layout patterns read from the layout storage unit.

  After selecting the cell work table layout pattern, the component input means assigns the type of component to be accommodated to each component box of the selected layout pattern. The combination of the component box and the component type is stored in the combination storage unit.

  And when the acquisition order (assembly order) of the parts in the predetermined product to be produced is input in the order input means, this is stored in the order storage means, and by the signal creation means based on the acquisition order of the parts, A notification control signal that defines the notification order of the notification devices on the cell work table is created. The created notification control signal is transmitted to the cell work table by the signal transmission unit, and the cell work table is notified (lights up or the like) based on the part acquisition order in the cell work table.

As described above, when the cell work table layout pattern changes, the corresponding layout pattern can be selected from a plurality of layout patterns, so it is possible to respond quickly without rewriting the control program one by one. Can do. Therefore, it is possible to quickly respond to the demand for production of a small variety of products.

In addition, the layout pattern of the cell work table can be changed by rearranging the frame body composed of pipe frames.

  Preferably, the apparatus further comprises layout input means for registering the new layout pattern, and the layout storage means is configured to further store the layout pattern input by the layout input means.

  In this case, when a cell work table having a new layout pattern is introduced, the new layout pattern is input by the layout input means. Therefore, even when a cell work table having a new layout pattern is introduced, it is possible to respond quickly without changing the control program.

  Preferably, the cell work table includes a top plate for performing a manufacturing operation, a frame body including a pipe frame, a plurality of component boxes that can be attached to the pipe frame, the notification device that is attached to each of the component boxes, and a bar. A barcode reader that reads encoded product information to be manufactured, and is connected to the barcode reader and transmits the product information read from the barcode reader to the signal transmission means of the cell worktable control device. And a signal transmission / reception unit that is connected to the notification device and receives a notification control signal transmitted from the signal transmission means of the cell worktable control device.

A notification device such as a notification lamp is attached to each component box. The signal transmission / reception unit is communicably connected to the signal transmission means of the cell worktable control device, and is also connected to the barcode reader and the notification device. And the notification control signal transmitted from the signal transmission means of the cell work table control device is received, and the notification device sequentially notifies (lights up, etc.) based on the notification control signal. Further, when the bar code reader is used to read the information on the product to be manufactured, the signal transmitting / receiving unit transmits the information on the product to the signal transmission means of the cell work table control device.

  Thus, since a frame is comprised with a pipe frame, the freedom degree with respect to the change of the layout pattern of a component box can be raised. In addition, by reading the product information with a barcode reader and transmitting the product information to the cell worktable control device, a notification control signal necessary for the cell worktable is quickly and accurately transmitted to the cell worktable control device. Can do.

  Further preferably, the signal transmission means and the signal transmission / reception unit are configured to be capable of wireless communication with each other.

  In this case, various signals are transmitted / received by radio communication between the signal transmitting / receiving unit of the cell work table and the signal transmission means of the cell work table control apparatus. As a result, the cell work table and the cell work table control device can be installed at separate locations, so the production site (cell work table) and the control management site (cell work table control device) are separated. However, it can be easily introduced without the need for wiring work. In addition, when a plurality of cell work tables are controlled and managed in one cell work table control apparatus, wiring is not complicated, which is particularly effective.

  Preferably, the cell work table includes a first sensor that detects the removal of the component from the component box for each component box, and a component box that is notified by the notification device to the first sensor. An error notification buzzer for notifying a work error when the removal of the part from a different parts box is detected, the signal transmission / reception unit being connected to the first sensor, and the first sensor being the work When an error is detected, a work error signal is transmitted to the signal transmission means of the cell work table controller.

  In this case, it is detected by the first sensor whether or not a component in the component box has been taken out from each of the plurality of component boxes. When the first sensor detects that a part has been taken out from the parts box not notified by the notification device, the error notification buzzer sounds an alarm sound to notify the operator of the error, and the signal transmission / reception unit causes a work error. The signal is transmitted to the signal transmission means of the cell worktable control device. Accordingly, the operator himself can confirm whether or not a predetermined product is manufactured in the correct assembly order, and can be collectively managed in the cell work table control apparatus.

  Further preferably, the cell work table control device receives the work status signal based on the detection status of the first sensor of the cell work table including the work error signal in the signal transmission means, and receives the received signal. Work log storage means for storing work progress status as work log data based on the work status signal is provided.

  In this case, the detection status of the first sensor provided in the parts box of the cell work bench including the work error is transmitted as a work status signal from the signal transmission / reception unit of the cell work bench to the signal transmission means of the cell work bench controller. The cell work table control device that has received the work status signal stores the work progress status as work log data in the work log storage means.

  As a result, in the cell worktable control device, the progress of work on the cell worktable can be managed cumulatively, and it can be used as a material for reviewing the suitability of the worker, the product production order, etc. Production control can be performed.

  Preferably, in order to solve the second problem, the cell workbench is configured to be able to install a component assembly jig on the top plate, and when the first sensor detects removal of an appropriate component The laser pointer that indicates the component assembly position of the component assembly jig corresponding to the component detected by the first sensor and the component assembled at the proper component assembly position are arranged corresponding to the component assembly position. And a second sensor for detecting whether or not.

  In this case, a component assembling jig is installed on the top plate, and the laser pointer is adjusted so as to irradiate the laser beam to the component assembling position of the component assembling jig. When the first sensor detects removal of an appropriate component, the laser pointer irradiates a laser beam to a component assembly position on a corresponding component assembly jig to indicate a position where the component to be extracted is assembled. The operator assembles the component at the component assembly position indicated by the laser pointer. The second sensor is arranged corresponding to the assembly position of the component, and detects whether the component assembly operation of the worker is appropriate.

  In this way, the operator can visually guide the worker to the actual part assembly position by the laser pointer, and can also determine whether or not the part assembly work of the worker is appropriate by the second sensor. Component assembly errors can be effectively prevented.

According to the cell workbench control system according to the present invention, if the cell change workbench layout pattern occurs, it is possible to select a layout pattern corresponding from a plurality of layout patterns, the control program every time It is possible to respond quickly without rewriting. Therefore, it is possible to quickly respond to the demand for production of a small variety of products.

Further, according to the cell workbench control system according to the present invention, whether with visually induce workers to the actual component mounting position by the laser pointer, or the operator of the parts assembling operation by the second sensor is properly Therefore, it is possible to effectively prevent an operator from assembling a component.

  As shown in FIG. 1, in the cell worktable control system according to the present embodiment, a plurality of component boxes 13 provided with a notification lamp 14 as a notification device are arranged based on a predetermined layout pattern to produce a predetermined product. The cell work table 1 for turning on the notification lamp 14 of the component box 13 to which the corresponding part is assigned, and the cell work table 1 are communicably connected to each other, based on the part acquisition order for performing the cell work. The cell work table control system includes a cell work table control device 2 capable of transmitting the lighting order of the notification lamps 14 to the table 1. As shown in FIG. 2, the cell work table control device 2 includes a layout storage unit 2121 that stores a plurality of layout patterns of the cell work table 1, and a plurality of layout patterns stored in the layout storage unit 2121.

And a type of component assigned to the component box 13 are read out, and a notification control signal defining the lighting order of the notification lamps 14 provided in the component box of the component is created in accordance with the acquisition order of the components. Signal generating means 213 and signal transmission means 22 for transmitting the notification control signal generated in the signal generating means 213 to the cell work table 1 are provided.

  The cell work table 1 includes a top plate 12 for performing a manufacturing operation, a frame body 11 made of a pipe frame, a plurality of component boxes 13 that can be attached to the pipe frame, and a notification lamp that is attached to each of the component boxes 13. 14, a barcode reader 15 that reads the information of the product to be manufactured that has been converted into a barcode, and the information on the product that is connected to the barcode reader 15 and is read from the barcode reader 15 A signal transmission / reception unit 16 that transmits to the signal transmission means 22 of the device 2 and is connected to the notification lamp 14 and receives a notification control signal transmitted from the signal transmission means 22 of the cell worktable control device 2. Configured as follows.

  As shown in FIG. 1, a top plate 12 for performing work and a plurality of component boxes 13 are attached to a frame 11 made of a pipe frame. A notification lamp 14 is attached to each component box 13. The notification lamp 14 may be an LED or the like as appropriate. Further, the notification lamp 14 may be directly attached to the component box 13 or may be attached to a predetermined portion of the frame body 11. The signal transmitting / receiving unit 16 is communicably connected to the signal transmission means 22 of the cell work table control device 2 and is also connected to the bar code reader 15 and the notification lamp 14. As the signal transmission / reception unit 16, for example, a communication / IO control device is used. And the notification control signal transmitted from the signal transmission means 22 of the cell worktable control device 2 is received, and the notification lamps 14 are sequentially turned on based on the notification control signal. In addition, when the information on the product to be manufactured is read by reading the barcode attached to the product specification or the like using the barcode reader 15, the signal transmission / reception unit 16 transmits the signal transmission of the cell worktable control device 2. The product information is transmitted to the means 22.

  Thus, since the frame 11 is comprised by a pipe frame, the freedom degree with respect to the change of the layout pattern of the component box 13 in the cell work table 1 mentioned later can be raised. Further, the product information is read by the bar code reader 15 and the product information is transmitted to the cell work table controller 2, so that a notification control signal necessary for the cell work table 1 can be quickly and accurately transmitted to the cell work table controller 2. Can be sent to.

  In the cell work table 1 of the present embodiment, as shown in FIG. 1, the opening of the component box 13 is attached so as to be inclined toward the front side (operator side), but this is not limitative. The shape of the component box 13 is not limited. Moreover, it is good also as a structure which suspends components with a suspension hook etc. as the component box 13. FIG. As will be described later, the number of component boxes 13 attached to the cell work table 1 is not limited to that shown in FIG. Further, the cell work table 1 may be rearranged in accordance with a layout pattern change described later, or may be replaced with a cell work table 1 having another layout pattern. In addition, the notification device can apply notification means that can be recognized by the operator, such as a liquid crystal display device, instead of the notification lamp 14.

  In the present embodiment, the product information is converted into a barcode and the barcode reader 15 is used. However, the product information is registered in an IC chip or IC tag instead of the barcode, and such an IC chip is used. Alternatively, an IC chip reader or an IC tag reader that can read information registered in the IC tag may be applied.

  The cell work table 1 includes a sensor 17 as a first sensor for detecting the removal of the component from the component box 13 for each component box 13, and the notification lamp 14 is lit by the sensor 17. An error notification buzzer 18 for notifying a work error when the removal of the component from the component box 13 different from the component box 13 is detected. The signal transmission / reception unit 16 is connected to the sensor 17. Is configured to transmit a work error signal to the signal transmission means 22 of the cell worktable control device 2 when the work error is detected.

  In this case, the sensor 17 detects whether or not a component in the component box 13 has been taken out from each of the plurality of component boxes 13. When the sensor 17 detects that a part has been removed from the parts box 13 where the notification lamp 14 is not lit, an error notification buzzer 18 sounds an alarm sound to notify the operator of the error, and the signal transmission / reception unit 16 The work error signal is transmitted to the signal transmission means 22 of the cell worktable control device 2. Thus, the operator himself can confirm whether or not a predetermined product is manufactured in the correct assembly order, and can be collectively managed in the cell worktable control device 2.

  The sensor 17 may be directly attached to the component box 13 or may be attached to a predetermined portion of the frame body 11. The sensor 17 includes various sensors such as a weight sensor that detects that a part has been taken out by a change in the weight of the parts box 13 and a photoelectric sensor that detects that a part has been taken out by blocking light. It can be adopted. These sensors 17 are preferably configured to be able to set a protection time until detection of removal (operation error) and a protection time until next detection at the same location after detection of removal. Thereby, even when an operator notices an error during taking out, the troublesomeness or malfunction that is detected as a work error can be prevented, and the worker can perform the production work more smoothly.

  Further, the cell work table body excluding the barcode reader 15 and the signal transmission / reception unit 16 (that is, the frame 11, the top plate 12, the parts box 13, the notification lamp 14, the sensor 17 and the error notification buzzer 18 in some cases) is provided. A plurality of bar code readers 15 and one signal transmission / reception unit 16 may be connected to a plurality of cell work table main bodies.

  Further, the cell work table control device 2 of the present embodiment receives the work status signal based on the detection status of the sensor 17 of the cell work table 1 including the work error signal in the signal transmission means 22, A work log storage unit 2124 is provided for storing the work progress status as work log data based on the received work status signal.

  In the present embodiment, the layout input unit 2114 for registering the new layout pattern is further provided, and the layout storage unit 2121 is configured to further store the layout pattern input by the layout input unit 2114. Is done.

  In the present embodiment, a personal computer 21 is used as the cell work table control device 2. Then, the input device 211 such as the keyboard 211a and the mouse 211b is used as the selection unit 2111, the component input unit 2112, the order input unit 2113, and the layout input unit 2114, and the layout storage unit 2121, the combination storage unit 2122, the order storage device 2123, and the work. The storage unit 212 such as a hard disk or a RAM is used as the log storage unit 2124, and the CPU is used as the signal generation unit 213, and each functions while being connected to the signal bus 214. In this embodiment, a wireless LAN access point is connected to a personal computer as the signal transmission means 22.

  Therefore, the signal transmission means 22 and the signal transmission / reception unit 16 are configured to be capable of wireless communication with each other. In this case, various signals are transmitted and received by radio communication between the signal transmitting / receiving unit 16 of the cell work table 1 and the signal transmission means 22 of the cell work table control device 2. As a result, the cell work table 1 and the cell work table control device 2 can be installed at separate locations, so the production site (cell work table 1) and the control management site (cell work table control device 2). Even if they are separated from each other, they can be easily introduced without the need for wiring work. Further, in the cell worktable control system of the present embodiment, a single cell worktable control device 2 can control and manage a plurality of cell worktables 1, but in that case, wireless communication makes wiring complicated. This is particularly effective.

  Next, the control flow of the cell worktable control system of this embodiment will be described in more detail. FIG. 3 is a flowchart in the cell worktable control system of FIG.

  First, in the cell work table 1, the worker can make a product of the corresponding product bar-coded based on a production instruction (specification) of a predetermined product (or an intermediate part in the middle of product production) to be produced. Information is read by the barcode reader 15 (step S1). The product information includes the type, number, assembly order, and the like of parts necessary for product manufacture. As described above, the product information read by the barcode reader 15 is wirelessly communicated by the signal transmission / reception unit 16 and transmitted to the signal transmission means 22 of the cell work table control device 2. The cell work table control device 2 receives the product information through the signal transmission means 22 (step S2).

  Product change processing is performed in the personal computer 21 of the cell worktable control device 2 (step S3). FIG. 4 is a flowchart of the product change process of FIG.

  There are cases where it is necessary to change the layout pattern of the cell work table 1 and cases where it is not necessary by changing the product to be manufactured (step S31).

  Here, the layout pattern of the cell work table 1 is a combination of the number (column number and / or number of stages) and size (width and / or height) of the plurality of component boxes 13 attached to the cell work table 1. is there. The cell work table control device 2 stores a plurality of layout patterns of the cell work table 1 in the layout storage unit 2121. FIG. 5 is a diagram showing an example of a cell work table layout pattern. As shown in FIGS. 5A to 5D, various layout patterns are stored in the layout storage unit 2121.

  When the layout pattern of the cell work table 1 is changed (Yes in step S31), the worker uses the selection unit 2111 (such as the mouse 211b) to select a plurality of layout patterns read from the layout storage unit 2121. A corresponding layout pattern is selected from among them (step S34).

  In the present embodiment, when there is no layout pattern to be selected (necessary for product change) in the layout storage unit 2121, a new layout pattern can be input by the layout input unit 2114.

  If it is necessary to add a new layout pattern (Yes in step S32), the layout input unit 2114 is used to input a necessary new layout pattern. The input new layout pattern is additionally registered in the layout storage unit 2121 (step S33). Thereby, in step S34, the newly registered new layout pattern can also be selected by the selection means 2111. Therefore, even when the cell work table 1 having a new layout pattern is introduced, it is possible to respond quickly without changing the control program. When inputting a new layout pattern, the number of columns / columns and the size of the component box 13 may be input numerically from the keyboard 211a, or the component box 13 and the frame body may be displayed on the screen of the personal computer 21 with the mouse 211b. 11 may be input by drawing and arranging.

  After selecting the layout pattern, it is compared whether or not the number of necessary component types in the product information received in step S2 is smaller than the number of component boxes 13 in the selected layout pattern (step S35). If the number of types of parts is greater than the number of parts boxes 13 (No in step S35), not all the parts necessary for production can be placed on the work table 1 with the selected layout pattern. An error is displayed (step S40), and reselection of the layout pattern is prompted.

  After selecting the layout pattern of the cell work table 1, the component input means 2112 is used to assign the type of component to be accommodated to each of the component boxes 13 of the selected layout pattern (step S36). The combination of the component box 13 and the component type is stored in the combination storage unit 2122.

  When assigning the parts box 13 to the parts, the parts box 13 is numbered in advance (configured so as to be recognized as a parts box ID code on the computer) along the layout pattern of the cell work table 1, and the parts box A part corresponding to the number assigned to 13 (similarly configured to be recognizable as a part ID code) is input. For example, in the cell work table 1 of FIG. 1, numbering is performed as No. 1, No. 2, No. 3, No. 4 from the upper left and No. 5, No. 6, No. 7, No. 8 from the lower left. , B,..., H are assigned. This combination is transmitted to the operator via the signal transmission / reception unit 16 of the cell work table 1 or separately transmitted to a person who replenishes the cell work table 1, The combination of the box 13 and the part type is managed so as not to cause wrinkles.

  Subsequently, the acquisition order (assembly order) of parts in a predetermined product to be manufactured is input using the order input unit 2113 (step S37). At the time of input, it is possible to simply input the part name or the corresponding part box 13 or click the mouse 211b to select the image of the cell work table 1 on which the part box 13 is arranged. It is good to do. The acquisition order of the input parts is stored in the order storage unit 2123. Further, the signal creation means 213 creates a notification control signal that defines the lighting order of the notification lamps 14 in the cell work table 1 based on the acquisition order of the parts (step S38). The created notification control signal is transmitted to the cell work table 1 by the signal transmission means 22 (step S39).

  If the layout pattern is not changed in step S31 (No in step S31) and the combination of the component and the component box 13 needs to be changed (Yes in step S41), the combination is determined in step S35. After the change is made, a new part acquisition order is input, and if there is no need to change the combination of the part and the part box 13 (No in step S41), only the new part acquisition order is input. Thus, a new notification control signal accompanying the product change is created and transmitted to the cell work table 1 (steps S37 to S39). As described above, when there is no change in the layout pattern (small changes in specifications such as variations in one product), the layout pattern change processing (steps S32 to S35) can be omitted. It can cope with specification changes.

  When the notification control signal created by the product change process in step S3 (FIG. 3) is received by the signal transmission / reception unit 16 of the cell work table 1, the signal transmission / reception unit 16 acquires the received neglect control signal (that is, acquisition of a part). Based on the order), the notification lamps 14 corresponding to the component boxes 13 containing the corresponding components are sequentially turned on, and the production of the product is started (step S4). For example, in the above-described example (parts A to H assigned to the part box 13 numbered 1 to 8), the parts are assembled in the order of part C → part D → part H → part E → part D → part F. In the case of (acquisition), first, the notification lamp 14 of the third part box 13 is turned on, and after the sensor 17 confirms the removal of the part C, the notification lamp 14 of the fourth part box 13 is turned on. Similarly, the notification lamps 14 corresponding to the parts boxes 13 of No. 8 → No. 5 → No. 4 → No. In the production of one product, it is not necessary to use all the component boxes 13 and it is also permitted to take out components (the same components) from the overlapping component boxes 13 in different processes.

  As described above, when the layout pattern of the cell work table 1 is changed, a corresponding layout pattern can be selected from a plurality of layout patterns, so that the control program can be dealt with quickly without rewriting each time. be able to. Therefore, it is possible to quickly respond to the demand for production of a small variety of products.

  In the present embodiment, based on the detection result of the sensor 17, for each part picking work in the cell work table 1, the work status signal is the signal transmission / reception unit 16 of the cell work table 1 regarding which part box 13 the part has been picked up from. Are sequentially transmitted to the signal transmission means 22 of the cell worktable control device 2 (step S6). The cell work table control device 2 that has received this work status signal stores the work status in the work log storage means 2124 as a time-series work log (step S8).

  During the work on the cell work table 1, if the operator takes out a wrong part or takes out the wrong order, the sensor 17 detects a work error (Yes in step S <b> 5). At this time, the signal transmission / reception unit 16 of the cell work table 1 sounds an error notification buzzer 18 to notify the operator of the operation error, and also provides information on the process in which the operation error has occurred and the component box 13 in which the operation error has occurred. It transmits to the signal transmission means 22 of the cell worktable control apparatus 2 as a work error signal (step S7). The cell work table control device 2 that has received the work error signal stores information on the work error in the work log storage unit 2124 as a work log (step S8). Instead of the error notification buzzer 18 or in combination with the error notification buzzer 18, the lighting mode of the notification lamp 14 may be changed (always on → blink).

  Thus, the detection status of the sensor 17 provided in the component box 13 of the cell work bench 1 including the work error is transferred from the signal transmission / reception unit 16 of the cell work bench 1 to the signal transmission means 22 of the cell work bench controller 2. The cell work table control device 2 that has been transmitted as a signal (step S6 or step S7) and has received the work status signal causes the work log storage means 2124 to sequentially store the work progress status as work log data (step S8).

  As a result, the cell work table controller 2 can log and store the progress of work on the cell work table 1 (work time for each part assembly process, etc.) in a cumulative manner. As a result, it is possible to know time-consuming or erroneous operations or procedures for each worker or each product, and it can be used as a material for reexamination of the suitability of the worker, product production order, etc. Production control can be performed. In addition, the replenishment of parts to the parts box 13 can be performed more efficiently by managing the work log in the cell worktable control device 2. The replenishment of parts is preferably performed by wireless communication (e-mail or the like) from the cell worktable control device 2 to a department (computer) that manages the parts. This makes it possible to perform replenishment work and management with no time loss and no leakage.

  The above steps S5 to S8 are repeated until the worker makes a predetermined amount of a predetermined product (No in step S9). After a predetermined amount of the predetermined product has been manufactured (Yes in Step S9), when a different product is manufactured (Yes in Step S10), the operation is repeated from Step S1.

  Subsequently, a cell worktable control system according to a second embodiment of the present invention will be described. FIG. 6 is a schematic front view showing a cell worktable control system according to the second embodiment of the present invention. FIG. 7 is a schematic side view of the cell worktable control system of FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Further, in FIG. 6, the cell work table control device 2 of FIG. 1 is not shown, and in FIG. 7, the cell work table control device 2, the barcode reader 15 and the signal transmission / reception unit 16 are not shown.

  This embodiment is different from the first embodiment in that the cell work table 1 is configured such that the component assembly jig 120 can be installed on the top plate 12, and the sensor 17 as the first sensor takes out an appropriate component. The laser pointer 19 that indicates the component assembly position P of the component assembly jig 120 corresponding to the component detected by the sensor 17 and the first component that detects whether the component has been assembled at the proper component assembly position P is detected. And a sensor 20 as a second sensor.

  In the cell work table 1 of the present embodiment, a unit in which the sensor 17 and the notification lamp 14 are integrated is provided on the front surface of the component box 13, but functionally, the sensor 17 and the notification in FIG. It has the same function as the lamp 14.

  On the top plate 12, a component assembling jig 120 is installed. This part assembly jig 120 carries parts that have been assembled in this process (part assembly work performed on the same cell work table) together with the part assembly jig 120 to the next process (part assembly work performed on another cell work table). The component assembly jig 120 is attached and detached for each assembly operation (a spare (next use) component assembly jig 120 is placed as shown in FIG. 7). Therefore, the top plate 12 is configured so that the component assembling jig 120 is installed at the same position every time. Specifically, a recess is provided on the top plate 12 and the component assembly jig 120 is fitted therein, or a stopper that restricts the horizontal movement of the component assembly jig 120 is provided on the top plate 12. Can be realized. Alternatively, the installation position of the component assembling jig 120 may be simply marked on the top plate 12, and the component assembling jig 120 may be installed according to the position.

  FIG. 8 is a view showing the component assembling jig of FIG. FIG. 8A is a view of the component assembly jig as viewed from above, and FIG. 8B is a diagram of the component assembly jig as viewed from the front. The part assembling jig 120 is used, for example, when assembling a molding part to an exterior part of an automobile, and a predetermined part is fitted to a predetermined position of the jig (for example, a part assembling position P) according to the shape of the jig. It is a jig for assembling parts by attaching so as to fit, and generally has a different shape for each product.

  A plurality of laser pointers 19 are attached so as to be suspended from the frame 11 at the top of the cell work table 1. These laser pointers 19 are attached by the number of component assembly positions P of the components to be assembled in this process in the component assembly jig 120 fixed to the top plate 12. And it adjusts so that each of the laser beam 190 of the laser pointer 19 may be irradiated to each of the component assembly positions P of the component assembly jig 120. Further, the component box 13 of the sensor 17 that detects the removal of the component is associated with the laser pointer 19 that irradiates the laser beam 190 to the component assembly position P corresponding to the component box 13.

  On the other hand, the sensor 20 as the second sensor is attached to the frame body 11 located near the top of the top plate 12 so that the detection portion of the sensor faces the operator, and the component assembly jig The number corresponding to the position corresponding to 120 component assembly positions P is attached. As with the sensor 17, various sensors such as a photoelectric sensor that detects that a component has been taken out by blocking the light can be used as the sensor 20. The sensor 20 is also preferably configured to be able to set the protection time until the component assembly error detection and the protection time until the next detection at the same location after the component assembly detection. Thereby, even when an operator notices an error during component assembly, the troublesomeness and malfunction that are detected as an operation error can be prevented, and the operator can perform the production work more smoothly. Further, the laser pointer 19 irradiated with the laser beam 190 and the sensor 20 corresponding to the component assembly position P irradiated with the laser beam 190 are associated with each other. Various mounting modes of the sensor 20 can be adopted depending on the component assembly position P where the components are assembled on the same cell work table 1. For example, when it is assumed that a plurality of components are assembled in the front-rear direction (depth direction of the top plate 12) toward the worker on the same cell work table 1, the left-right direction (width direction of the top plate 12) is also provided. Or two sensors with different sensitivities are provided at the same position and in the same orientation (for example, at the part assembly position P close to the sensor, the two sensors detect both, but the parts far from the sensor For example, the assembly position P can be detected by only one sensor).

  When changing the product to be manufactured, adjust the laser pointer 19 and the sensor 20 each time (attachment position, change adjustment of the irradiation direction of the laser light 190 and the sensor detection direction, the number of the laser pointers 19 and the sensors 20 to be attached). The number may be increased or decreased), or may be attached in advance so as to correspond to the component assembly jig 120 of a plurality of products. It is also possible to make the laser pointer 19 and the sensor 20 movable so as to correspond to each other.

  According to the above configuration, when the sensor 17 detects the removal of an appropriate component (No in step S5 in FIG. 3), the laser pointer 19 corresponding to the detected sensor 17 is placed on the corresponding component assembly jig 120. The component assembly position P is irradiated with the laser beam 190 to instruct the position for assembling the extracted component. Since the laser light 190 is used, it is possible to irradiate at a pinpoint, so that the possibility of operator misidentification can be reduced. Note that, depending on the components, there may be a plurality of component assembly positions P at the same timing, so that a plurality of laser pointers 19 are allowed to irradiate each component assembly position P at the same time.

  The operator assembles the component at the component assembly position P indicated by the laser pointer 19.

  When an operator assembles a component at the component assembly position P in accordance with an instruction from the laser pointer 19, the sensor 20 detects the component assembled or the operator's hand that has been pushed out for assembly. When the sensor 20 detects the assembly of the component, it is determined whether or not the laser pointer 19 corresponding to the detected sensor 20 is irradiating the laser light 190. In the case of the laser pointer 19 irradiating the laser beam 190, it is determined that the worker's component assembling work is appropriate, and the work is continued. On the other hand, if it is not the laser pointer 19 that is irradiating the laser beam 190, it is determined that the component assembling work of the worker is not appropriate, and the worker is notified of the component assembling error. Examples of the manner of notifying the assembly error include performing flashing irradiation of the laser beam at the laser pointer 19 that is irradiating the laser beam 190, or notifying the error notification buzzer 18 by voice.

  As described above, the operator can be visually guided to the actual part assembly position P by the laser pointer 19, and the operator can also determine whether or not the part assembly work of the worker is appropriate by the sensor 20 as the second sensor. Therefore, it is possible to effectively prevent an operator from assembling the components.
