  The feeder preparation button 81 is pressed by an operator when the feeder 13 is replaced or the supply tape is replenished. When the feeder preparation button is pressed while the feeder is lit, the feeder 3 is unlocked and can be replaced.

  In such an electronic component mounting apparatus 100, conventionally, from the viewpoint of safety, two feeder carts 50 are installed and the open / close cover 23 is not closed so that an operator does not access the apparatus during operation. And can't start driving. However, as in recent years, there are many types of switching, and there is a demand for independent production even in dual line devices.

  Therefore, in this embodiment, the feeder area cover is closed so that the operator cannot access the feeder area side where the feeder cart 50 is mounted. Therefore, based on the operator's instruction to remove the feeder cart 50, the feeder cart 50 of the other production line is detached and switched to a new feeder cart 59 within a range that does not interfere with production of the production line in operation, or It is possible to perform other setup operations as much as possible including the setup in the feeder cart 50. In the following description, when at least one of the two production lines is in an operating state, the feeder cart 50 is replaced or replaced or replenished with the other one production line, and the same feeder cart 50 is loaded / unloaded. This process is called feeder cart loading / unloading mode.

  FIG. 5 is a diagram showing a first example of the feeder cart loading / unloading mode of the present embodiment, that is, a diagram showing a feeder cart loading / unloading operation flow for replacing the feeder cart. The upper part of the drawing shows the feeder area 3U where the feeder cart 50U of the production line U currently in operation exists, and the lower part of the drawing shows the feeder area 3T where the feeder cart 50T of the target production line T currently stopped. The former feeder area 3 is referred to as a use block 3U, and the latter feeder area 3 is referred to as a target block 3T.

  First, when the model work of the target production line T is completed, the control device 28 determines whether the feeder cart 50T of the target block 3T can be attached or detached according to the determination flow shown in FIG. In the present embodiment, the determination result is indicated by the display content of the feeder preparation (FEEDER REDAY) button 81 shown in FIG. 4 (Step 1). The feeder preparation button 81 is turned on when the feeder 3B is normally supplying electronic components, and is turned off under a predetermined condition such as when the feeder 3B needs to be replaced or when the production operation is stopped. . In this example, as a result of the determination, the light is turned off if the attachment / detachment is possible and the light is turned on if impossible.

  As a result, the operator can know whether or not the feeder cart 50T can be attached / detached from the display state of the feeder preparation button 81. When the feeder preparation button 81 is lit, it is recognized that the feeder cart 50T is locked, that is, the feeder fixing portion 52 is locked so as not to descend. On the other hand, when it is turned off, it is recognized that the feeder area cover is closed.

  Note that whether or not the feeder cart 50T can be attached or detached may be determined by the indicator lamp 22 indicating the operation status of the target production line T. The indication of whether or not the feeder cart 50 can be replaced is not simply turned on / off, but the lighting color of the feeder preparation button 81 and the indicator lamp 22 may be changed according to the state, or displayed on the screen of the monitor 21. May be.

Next, if it is necessary to replace the feeder cart 50T and the display of the feeder preparation button 81 indicates that the feeder cart 50T is removable, the operator presses the feeder preparation button 81T to instruct replacement of the feeder cart 50T. If the feeder cart 50T is detachable, the feeder fixing portion 52 of the feeder cart 50T is lowered to be in a detachable state (Step 2).
As the instruction means, instead of using the feeder preparation button 81, a dedicated button may be provided. Other means may be used instead of the button.

  Next, in order to replace the operator with a new feeder cart 50N prepared for the next model to be produced, the operator removes the collective signal transfer cable 57 shown in FIG. 3 from the feeder cart 50T and removes the feeder cart 50T from the feeder cart 50T. Remove from area 3. Then, the collective signal transfer cable 57 is connected to the new feeder cart 50N, and the new feeder cart 50N is attached to the feeder area 3 (Step 3).

  Next, the operator presses the feeder preparation button 81T that is turned off. The control device 28 confirms the connection of the collective signal transfer cable 57 with the new feeder cart 50N and raises the feeder fixing portion 52 of the new feeder cart 50N (Step 4). When the operator then presses a start (START) button 83 shown in FIG. 4 to start operation of the production line T in which the feeder cart 50 has been replaced, the feeder preparation button 81 is lit.

  FIG. 6 shows a determination flow for determining whether the attachment / detachment is possible. As shown in the flow of FIG. The target production line is suspended (Step 11), the feeder area cover is closed (Step 12), is not the simultaneous transfer mode but the independent production mode (Step 13), and even in the independent production mode, In the fully independent production mode (Step 14), and even in the quasi-independent production mode, the target production line T is present, but the target block 3T has no feeder to be used in the production line U (Step 15). The feeder cart 50 of the target block 3T can be attached and detached. In the first embodiment, if the attachment / detachment is possible, the feeder preparation button 81T is turned off (Step 16), and if the attachment / detachment is impossible, the feeder preparation button is continuously turned on (Step 17). For example, the lighting is continued when the component supply is normal in the simultaneous loading mode.

  Even in the case of an electronic component mounting apparatus, the conditions of Step 13 are omitted when there is no simultaneous entry production mode, and Steps 14 and 15 are omitted when there is only a completely independent production mode. Therefore, in the first embodiment, it is determined whether at least the target production line is at rest or the feeder area cover is closed, and the feeder cart 50 is removed.

  According to the first embodiment described above, in the electronic component mounting apparatus that is a dual line apparatus provided in two production lines, even when one production line is in operation, the feeder of the other production line can be more safely operated. The feeder cart of the area can be removed, and an electronic component mounting apparatus and an electronic component mounting method with a high operating rate can be provided.

  Next, a feeder cart loading / unloading operation flow for replacing a feeder cart, which is a second example of the feeder cart loading / unloading mode of the present embodiment, will be described with reference to FIG. In FIG. 7, the operation flow shown in the upper part shows the operation flow for replacing the normal feeder 3B, and the lower part shows the operation flow for installing / removing the feeder cart in the second example of this embodiment. . In FIG. 7, as in FIG. 5, the constituent element of the production line currently in operation on the upper side of the drawing is indicated by the suffix U, and the constituent element of the target production line is indicated by the suffix T.

  To replace the feeder 3B shown in the upper row, the feeder preparation button 81T is simply pressed to turn it off (Step 31), whether it is in operation or at rest, and the clamp of the feeder 3B displayed on the monitor 21 is released. Then, the feeder is inserted and removed or the supply tape is replenished (Step 32). Then, after several seconds, the feeder 3B is clamped, and the feeder preparation button 81T is turned on again (Step 33). This process is called feeder replacement mode. The operation flow in this feeder replacement mode is the same in the first embodiment and other embodiments.

  On the other hand, in the second embodiment in which the feeder cart 50 shown in the lower part is replaced, unlike the first embodiment, the operator can check the current driving situation even when the driver is operating, regardless of whether or not the driver cart is not operating. In this example, it is possible to realize a case where it is necessary to replace the feeder cart 50T in consideration of the above, that is, to detach the feeder cart 50T. In the second embodiment, in the determination flow for determining whether or not the attachment / detachment is possible as shown in FIG. 6, it is not determined whether Step 1 is paused, and at least the feeder area cover of Step 2 is confirmed to be closed. Replace the feeder cart 50T below the paper surface shown in FIG.

  As shown in Step 30, since the two feeder preparation buttons 81U and 81T are lit, the two production lines of the electronic component mounting apparatus 100 are in operation or in an operable state. First, the operator presses and holds the feeder preparation button 81T, and at least the state of the feeder area cover is determined in the determination flow shown in FIG. If the feeder cart 50T can be replaced, the feeder preparation button 81T is turned off, and the feeder fixing portion 52 of the feeder cart 50T is lowered (Step 34). The reason for long-pressing is to distinguish it from a request for replacing the feeder 3B by a single press.

  Next, the feeder cart 50T is replaced with a new feeder cart 50N in the same manner as in the first step 3 (Step 35). Thereafter, when the operator single-presses or long-presses the feeder preparation button 81T that is turned off (Step 36), the control device 28 confirms the connection of the collective signal transfer cable 57 with the new feeder cart 50N, and the new feeder The cart 50N is raised so that it can be operated, and then the feeder preparation button is turned on again (Step 37).

  According to the second embodiment described above, in the electronic component mounting apparatus which is a dual line apparatus provided for two production lines, even if the two production lines are both in operation, one feeder cart 50 can be replaced or When setup is required, the feeder cart 50 can be removed from the feeder area 3 while continuing the operation of the other production line, and an electronic component mounting apparatus and an electronic component mounting method with a high operating rate can be provided.

  Next, a feeder cart loading / unloading operation flow for replacing a feeder cart, which is a third example of the feeder cart loading / unloading mode of the present embodiment, will be described with reference to FIG. In FIG. 8, as in FIG. 5, the constituent elements of the currently operating production line on the upper side of the drawing are indicated by the suffix U, and the constituent elements of the target production line are indicated by the suffix T.

  The basic concept of the third embodiment is the same as that of the second embodiment. That is, regardless of whether or not the vehicle is at rest, the operator replaces the feeder cart 50T in consideration of the current driving situation even during driving. That is, when it is considered that the feeder cart 50T needs to be replaced, this is an example in which the replacement can be performed.

The third embodiment is different from the second embodiment in that the feeder cart is loaded and unloaded via the feeder replacement mode shown in the second embodiment. In FIG. 8, the upper side of the drawing shows the feeder replacement mode, and Step 40 to Step 42 are the same as Step 30 to Step 32 of FIG. 7 shown in the second embodiment. Further, the lower side of the drawing shows the feeder cart loading / unloading mode, and Step 42, Step 44 to Step 46 and Step 43 are basically the same as Step 32, Step 34 to Step 36 and Step 33 of the second embodiment shown in FIG.

  In such an operation flow, when the feeder preparation button 81T is pressed in the feeder replacement mode in Step 42, or in Step 42 in this embodiment, the feeder cart loading / unloading mode is entered and the same as in the second embodiment. Operate.

  The only difference is that the second embodiment uses a long press operation of the feeder preparation button 81 in the feeder cart loading / unloading mode to distinguish it from the single press operation of the feeder preparation button 81 in the feeder replacement mode. On the other hand, in the third embodiment, a double pressing operation of the feeder preparation button 81 is used. However, the operation of the feeder preparation button 81 may use the method of the third embodiment or the method of the third embodiment. Conversely, the method of the second embodiment or the method of the third embodiment may be used. . In short, the operation in the feeder replacement mode and the operation in the feeder cart loading / unloading mode may be changed.

  Further, the feeder replacement mode operation and the feeder cart loading / unloading mode may be performed using different buttons or different methods.

  According to the third embodiment described above, as in the second embodiment, when one feeder cart 50 needs to be replaced or set up even when the two production lines are both operating, Even when the production line is in operation, when the feeder cart 50 needs to be replaced or set up, the feeder cart 50 can be detached from the feeder area 3 while continuing the operation of the production line, and the operation rate Electronic component mounting apparatus and electronic component mounting method can be provided.

Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention. It includes modifications or variations.
