  In the tray supply apparatus 20 according to the present embodiment, the tray TR is transported to a position immediately below the tray supply position (the first tray supply position PR1 or the second tray supply position PR2) by the tray transport unit 22, and then the tray lift cylinder ( The first lift cylinder 51 or the second lift cylinder 52) is pushed up from the tray transport unit 22 to the tray supply position, and is held by the tray holding unit (the first tray holding unit 31 or the second tray holding unit 32) to be empty. After the tray TR is placed on the tray transport unit 22 from the tray supply position by the tray lifting cylinder and transferred, the tray TR is transported and collected by the tray transport unit 22. For this reason, it is possible to replace the tray TR at the other tray supply position while the tray TR is held at one tray supply position, and the tray TR can be replaced while the component mounting operation is being performed. Therefore, the tact loss is small and the productivity of the mounting board can be improved.

  In the component mounting apparatus 1 according to the present embodiment, an operation of taking out the component 4 from the tray TR supplied to the first tray supply position PR1 and mounting it on the substrate 2 positioned by the substrate positioning unit 14, and the second tray supply position The operation of taking out the component 4 from the tray TR supplied to the PR 2 and mounting it on the substrate 2 positioned by the substrate positioning unit 14 is performed in parallel (mixed) to detect the remaining number of components in the tray TR. Based on detection information from the remaining component number detection means, etc., the tray TR is replaced when it is detected that the tray TR is empty, so that the component mounting operation is executed without interruption. can do.

  Alternatively, the component mounting means (the component reversing unit 17 and the component mounting unit 18) is based on the operation of taking out the component 4 from the tray TR supplied to the first tray supply position PR1 and mounting it on the substrate 2, and supplying the first tray. When the component 4 in the tray TR supplied to the position PR1 is exhausted, the operation of taking out the component 4 from the tray TR supplied to the second tray supply position PR2 and mounting it on the substrate 2 may be performed. In this case, the replacement of the tray TR at the first tray supply position PR1 is performed while the component mounting means performs the operation of taking out the component 4 from the tray TR supplied to the second tray supply position PR2 and mounting it on the substrate 2. When the replacement of the tray TR at the first tray supply position PR1 is completed, the operation of taking out the component 4 from the first tray supply position PR1 and mounting it on the substrate 2 is resumed.

  Such a component mounting procedure is preferable in the component mounting apparatus 1 according to the present embodiment, when the first tray supply position PR1 and the second tray supply position PR2 are compared, the first tray supply position PR1 is the component. 4 is close to the substrate 2 to be mounted, the component 4 is taken out from the tray TR held at the first tray supply position PR1, and the component 4 from the tray TR held at the second tray supply position PR2 is removed. Rather than mixing and taking out, the parts 4 are first concentrated from the tray TR held at the first tray supply position PR1, and the components in the tray TR held at the first tray supply position PR1 are concentrated. The part 4 is removed from the tray TR held at the second tray supply position PR2 only when the part 4 is exhausted (the tray TR is empty). (Here inverted head 17a of the component inverted portion 17) component mounting means for movement distance is short, because it is on the mounting tact advantageous.

  Alternatively, as described above, when the component mounting unit is based on the operation of taking out the component 4 from the tray TR supplied to the first tray supply position PR1 and mounting it on the substrate 2, the tray supply device 20 When the component 4 in the tray TR supplied to the first tray supply position PR1 is exhausted, the tray TR on the first tray supply position PR1 is collected, and the tray TR on the second tray supply position PR2 is moved to the second elevating cylinder. 52, the tray TR is transported to a position immediately below the first tray supply position PR1 by the tray transport unit 22, and then the tray TR is moved by the first elevating cylinder 51 to the second position. The tray on the second tray supply position PR2 is pushed up to the first tray supply position PR1 to hold the tray TR on the first tray holding portion 31. Moves the Lee TR in the first tray supply position PR1, the tray TR may be of and supplies to the second tray feeding position PR2.

  In this case, the control device 19 first operates the first elevating cylinder 51, the tray transport unit 22 and the fourth elevating cylinder 54 in order, and the empty tray TR on the first tray supply position PR1 is transferred to the tray collection unit 34 as described above. After receiving (collecting) (FIG. 9 (a) → FIG. 9 (b)) and collecting the tray TR, the second elevating cylinder 52 is operated to attach the second tray support plate TS2 to the second tray holding portion 32. Is brought into contact with the lower surface of the tray TR held. When the tray TR positioned at the second tray supply position PR2 is supported by the second elevating cylinder 52 by operating the pair of clamp members 32a constituting the second tray holding portion 32 in the opening direction (FIG. 9 ( c)) By lowering the second tray support plate TS2 to a position below the transport surface SF of the tray TR by the belt conveyor 22a, both ends of the tray TR are supported by the belt conveyor 22a. As a result, the tray TR is transferred from the second tray supply position PR2 to the tray transport unit 22 (FIG. 9 (d) → FIG. 9 (e)).

  The control device 19 operates the tray transport unit 22 when the tray TR is transferred to the tray transport unit 22, and positions the tray TR on the tray transport unit 22 directly below the first tray supply position PR1 ( FIG. 9 (f)). Then, by operating the first elevating cylinder 51 to raise the first tray support plate TS1, the tray TR positioned immediately below the first tray supply position PR1 is pushed up to the first tray supply position PR1 (FIG. 9 ( g) → FIG. 9 (h)), the pair of clamp members 31a constituting the first tray holding portion 31 are operated in the closing direction to hold (clamp) the tray TR. As a result, the tray TR is supplied to the first tray supply position PR1.

  As described above, when the tray supply device 20 runs out of the component 4 in the tray TR supplied to the first tray supply position PR1, the second tray is accommodated after the tray TR supplied to the first tray supply position PR1 is accommodated. By moving the tray TR supplied to the supply position PR2 to the first tray supply position PR1, the frequency of taking out the component 4 from the first tray supply position PR1, which is advantageous in terms of mounting tact, is increased. The productivity of the substrate can be improved.

  The movement of the tray TR from the second tray supply position PR2 to the first tray supply position PR1 is performed so that the mounting operation of the component 4 on the substrate 2 is not delayed by the movement operation of the tray TR. This is performed while the replacement work of the board 2 on the positioning unit 14 (work for unloading the board 2 on which the component 4 has been mounted and loading and positioning a new board 2) is performed. Is preferred.

  Further, in the component mounting apparatus 1 according to the present embodiment, the tray that stores (collects) the tray TR pushed up by the cylinder mechanism (fourth elevating cylinder 54) as the collection unit of the tray TR that accommodates the empty tray TR. Although the tray collection unit 34 having the same configuration as that of the storage unit 33 is provided, the tray TR collection unit does not necessarily contain the tray TR while being pushed up by the cylinder mechanism. As shown in FIG. 6, the tray TR transported by the tray transport unit 22 may be dropped from the end of the tray transport unit 22 and stored. In the example shown in FIG. 10, a portion corresponding to the tray collection unit 34 shown in the above embodiment can also be used as the tray storage unit 33. In such a configuration, each tray storage unit 33 stores the tray TR storing the parts 4 of the same type, thereby reducing the number of times the empty tray TR is collected and the number of times the parts 4 are replenished. Can do. Further, for example, when the substrate 2 is a liquid crystal panel and a driver IC or the like is mounted on the substrate 2, a tray TR in which different types of components 4 (source side components and gate side components) are stored in each tray storage unit 33. By storing each of them, different components 4 can be supplied by one tray supply device 20, and thus the component mounting device 1 can be made compact.

  In the present embodiment, the substrate positioning unit 14 for positioning the substrate 2, the tray supply device 20, and the tray supplied to the first tray supply position PR1 and the second tray supply position PR2 by the tray supply device 20. The component mounting apparatus 1 including the component mounting means (the component reversing unit 17 and the component mounting unit 18) for taking out the component 4 from the TR and mounting it on the substrate 2 positioned by the substrate positioning unit 14 is a tray supply device having the above-described effects. Therefore, the production substrate can be efficiently produced.

  It is an object of the present invention to provide a tray supply device and a component mounting device that can perform tray replacement while a component mounting operation is being performed.
