Japanese Patent Laying-Open No. 2003-124688 (FIG. 3) JP-T-2006-522964 (claim 25, paragraph [0020], FIG. 3)

  In the conventional tape feeder, the number of parts to be supplied is reduced, and it is necessary to remove the tape feeder from the mounter when the parts are replenished by splicing for connecting the part tape or reel replacement. However, if the tape feeder is removed from the mounter while the mounter is in operation, the component suction nozzle 44 and the tape feeder 24 may come into contact with each other and be damaged. Therefore, it is necessary to temporarily stop the operation of the mounter in operation. . A similar problem occurs when a tape feeder that does not need to be removed is accidentally removed while the mounter is operating.

  The present invention has been made to solve the above-mentioned conventional problems, and it is possible to safely remove a component supply means such as a tape feeder without stopping the operation of the component mounting machine even while the component mounting machine is in operation. The problem is to enable efficient operation.

  The present invention provides a component mounting apparatus including a component supply unit having a lock mechanism that is detachable from a component mounter and needs to be released when the component mounter is removed. By providing means for detecting the release of the lock mechanism and means for controlling the component mounter in response to the release of the lock mechanism, the problem is solved.

  Here, when the component supply means of the substitute part is mounted on the component mounting machine, the control means sucks the component from the component supply means of the substitute part instead of the component supply means whose lock mechanism is released. In this way, the component mounter can be controlled.

  Further, the controlling means can actuate a display means for indicating a position of the component supplying means whose lock mechanism is released.

  Furthermore, it is possible to provide means for detecting that the component supply means has been removed from the component mounter, and to display differently depending on the release of the lock mechanism and the removal of the component supply means.

  According to the present invention, the component supply means can be safely removed even when the component mounter is in operation. Therefore, whenever the number of components is reduced, the component supply means can be removed from the component mounter, and splicing, reel replacement, etc. can be performed. Furthermore, by providing an alternative component supply means, it is possible to replenish components without stopping the apparatus.

  Moreover, even if the operator accidentally removes the component supply means that is operating, it can be safely removed.

  In particular, when a display means for indicating the position of the component supply means with the lock mechanism released is provided, it can be mounted without making a mistake in the mounting position when the component supply means is remounted.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In this embodiment, in the component mounting apparatus having the overall configuration as shown in FIG. 1, as shown in FIG. 2, the lock detection contact 26 for detecting the release of the lock mechanism 25 of the tape feeder 24, the feeder Corresponding to a lock release signal input from the control unit 27, a mounter control unit 72 for controlling the mounter 10 and a feeder position indicator lamp 74 for instructing a feeder mounting position are provided.

  In the figure, 28 is a feeder drive motor for driving a sprocket 29 for feeding a tape 23 in which a component 22 is accommodated.

  The operation will be described below with reference to FIG.

  While the mounter is in operation, the tape feeder 24 is fixed to the mounter 10 by the lock mechanism 25. In order to remove the tape feeder 24 from the mounter 10 when there are fewer parts left and the operator tries to perform splicing or reel replacement, the lock mechanism 25 must be unlocked.

  For this reason, when the lock of the tape feeder 24 is released in step S100 of FIG. 3, a lock release signal is input from the lock detection contact 26 to the tape feeder control unit 27, and the tape feeder control unit 27 sends to the mounter control unit 72. Send an unlock signal.

  As a result, the mounter control unit 72 turns on the feeder position indicator lamp 74 in, for example, yellow in step S102 and determines whether there is a feeder of an alternative part. If there is an alternative part, the alternative part is picked up in step S104 and mounting of the part is continued. If there is no alternative part, the pickup is skipped in step S106. When the suction is skipped, the suction is again performed after the tape feeder filled with the parts is attached.

  After releasing the lock of the tape feeder 24 in step S100, the process proceeds to step 110, where the tape feeder 24 is removed from the mounter 10. Thereby, the mounter control part 72 changes the lighting color of the feeder position indicator lamp 74 from yellow to red in step S112. Therefore, it can be seen that the tape feeder has been removed for parts replacement.

  After the tape feeder 24 is removed from the mounter 10 in step S110, the process proceeds to step S120, where parts are replenished by splicing or reel replacement. Next, the tape feeder 24 is attached to the mounter 10 in step S130. Thereby, the mounter control part 72 changes the lighting color of the feeder position indicator lamp 74 from red to yellow in step S132, for example.

  Next, when the tape feeder 24 is locked to the mounter 10 in step S140, the lock detection contact 26 notifies the mounter control unit 72 that the tape feeder 24 has been locked, and in step S142, the feeder position indicator lamp is turned off and the attached tape feeder 24 is attached. The adsorption operation for is resumed.

  In this embodiment, the feeder position indicator lamps that are lit in two colors are provided, and display is different depending on whether the lock is released or removed. Therefore, handling is extremely easy and the possibility of erroneous mounting is low. In addition, it is possible to notify only the unlocking by using an indicator lamp that is lit in a single color, or to omit the indicator lamp.

  In the embodiment, the output of the lock detection contact 26 is received by the feeder control unit 27 and then transmitted to the mounter control unit 72. However, the output of the lock detection contact 26 is not transmitted through the feeder control unit 27. Alternatively, it may be directly input to the mounter control unit 72.

  In the embodiment, the tape feeder is used as the component supply means. However, the component supply means is not limited to the tape feeder, and may be a component tray, for example. Further, the feeder position display means is not limited to the lamp, and may be an LED or a display.
