  However, in the above-described conventional component mounting apparatus, the tray transport unit not only transports the tray to the tray supply position as the component take-out position, but also serves to hold the tray at that position. When there are no more parts in the tray being supplied to the tray, the tray replacement operation is performed by first collecting the empty tray with no parts by the tray transport means, and then placing a new tray containing the parts in the tray supply position. It was necessary to follow the procedure of transporting to. For this reason, the tact loss accompanying the replacement of the tray is large, and there is a problem that the productivity of the mounting board may be lowered.

  SUMMARY An advantage of some aspects of the invention is that it provides a tray supply device and a component mounting device that have less tact loss associated with tray replacement.

  The tray supply apparatus according to claim 1 is a tray supply apparatus that is provided in a component mounting apparatus that mounts a component on a board and supplies a tray in which the component is stored to a tray supply position. A tray moving guide that guides the tray so that the tray slides from the tray standby position provided side by side to the tray supply position, and the tray on the tray standby position is slid along the tray movement guide and supplied to the tray supply position. Slide means and a tray placement member on which the tray is placed are moved horizontally and vertically along the tray movement guide below the tray movement guide, thereby supplying the tray to the tray standby position and sliding means. A tray supply and recovery mechanism for recovering the tray supplied from the tray standby position to the tray supply position.

  The tray supply device according to claim 2 is the tray supply device according to claim 1, wherein the tray supply / recovery mechanism is configured to support the tray placement member and the tray placement member so as to be movable up and down. Horizontal moving means for moving the horizontal moving body in the horizontal direction along the tray moving guide below the tray moving guide, and the tray mounting member in a state where the horizontal moving body is positioned below the tray standby position by the horizontal moving means. Move the tray up and down to feed the tray to the tray standby position, and move the tray mounting member up and down to collect the tray from the tray feed position with the horizontal moving body positioned below the tray feed position. It consists of dynamic drive means.

  The tray supply device according to claim 3 is the tray supply device according to claim 1 or 2, wherein the tray supply and recovery mechanism is empty when parts in the tray supplied to the tray supply position are lost. Then, the tray mounting member is moved up and down below the tray supply position to collect the empty tray on the tray supply position, and the tray on the tray standby position is slid by the sliding means and supplied to the tray supply position. The mounting member is moved up and down below the tray standby position to supply a new tray in which components are stored at the tray standby position.

  According to a fourth aspect of the present invention, there is provided a component mounting apparatus including: a substrate positioning unit that positions a substrate; the tray supply device according to any one of claims 1 to 3; and a tray that is supplied to the tray supply position by the tray supply device. Component mounting means for taking out the component and mounting the component on the substrate positioned by the substrate positioning unit.

  In the present invention, when the components in the tray supplied to the tray supply position are empty and the tray is replaced, the tray placing member is moved up and down below the tray supply position to move the tray on the tray supply position. After the tray is slid by the slide means and supplied to the tray supply position, the tray mounting member is moved up and down below the tray standby position to supply the tray to the tray standby position. At this time, the tray can be supplied to the tray standby position while the tray is being supplied to the tray supply position (that is, while the component mounting operation is being performed). The interruption time of the work is substantially only the time required for moving (sliding) the tray at the tray standby position to the tray supply position by the sliding means. For this reason, there is little tact loss accompanying tray replacement, and the productivity of the mounting substrate can be improved.

  In the present invention, the tray supply to the tray standby position and the tray recovery on the tray supply position are performed in the horizontal direction along the tray movement guide below the tray movement guide by placing the tray placement member on which the tray is placed. In addition, the tray supply and recovery mechanism configured to move in the vertical direction is used, and the vertical movement of the tray mounting unit at a plurality of locations is performed by a single drive means (vertical movement drive means). Therefore, the configuration is simple, and the manufacturing cost of the tray supply device, and hence the manufacturing substrate, can be reduced.

The tray supply / recovery mechanism 40 includes a tray mounting plate 41 as a tray mounting member for mounting the tray TR, a vertical movement member 43 having a tray mounting plate 41 attached to the upper end and a roller 42 at the lower end, A horizontal moving body 44 that supports the member 43 movably up and down, and a horizontal movement as horizontal moving means for moving the horizontal moving body 44 in the horizontal direction (Y-axis direction) along the tray movement guide 22 below the tray movement guide 22. The conveyor 45 includes a lifting plate 46 provided below the horizontally moving conveyor 45 in the Y-axis direction and a lifting cylinder 47 that moves the lifting plate 46 up and down.

  Here, since the roller 42 at the lower end of the vertical movement member 43 is in contact with the upper surface of the lifting plate 46 by its own weight, when the lifting plate 46 is lifted or lowered by the lifting cylinder 47, the tray placement is performed accordingly. The plate 41 moves up and down. That is, the elevating cylinder 47 is a vertical movement driving means for moving the tray mounting plate 41 up and down.

  The horizontal moving conveyor 45 and the lifting cylinder 47 are controlled by the control device 19. When the horizontal moving conveyor 45 is operated, the tray loading plate 41 rolls the roller 42 of the vertical movement member 43 on the upper surface of the lifting plate 46. However, when it moves in the horizontal direction (Y-axis direction) together with the horizontal moving body 44 and the lifting cylinder 47 operates, the tray mounting plate 41 moves up and down with respect to the horizontal moving body 44 together with the vertical movement member 43 as described above. . For this reason, the tray mounting plate 41 can be moved up and down at an arbitrary position below the tray moving guide 22 by combining the operation of the horizontally moving conveyor 45 and the operation of the lifting cylinder 47.

  In the tray supply device 20, when taking out one tray TR from a plurality of trays TR stored in the tray storage unit 26, the control device 19 first moves the horizontal moving body 44 by the horizontal moving conveyor 45. The tray mounting plate 41 is moved to be positioned immediately below the tray storage unit 26. Then, the elevating cylinder 47 is operated to move the tray mounting plate 41 upward (arrow B1 shown in FIG. 5A), and is positioned at the lowest position among the trays TR stored in the tray storage unit 26. The tray mounting plate 41 is brought into contact with the lower surface of the tray TR from below (FIG. 5A). Then, the pair of tray lower surface support members 32 provided in the tray storage unit 26 are operated in the opening direction (arrow B2 shown in FIG. 5B), and all trays stored in the tray storage unit 26 are stored. After the TR is supported by the tray mounting plate 41, the lifting cylinder 47 is operated to lower the tray mounting plate 41 by the thickness of one tray TR (in FIG. 5B). Arrow B3).

  When the control device 19 lowers the tray mounting plate 41 by the thickness of one tray TR, the control device 19 operates the pair of tray lower surface support members 32 in the closing direction (arrow B4 shown in FIG. 5C). Of the trays TR stored in the tray storage unit 26, all the trays TR other than the lowermost tray TR (above the lowermost tray TR) are a pair of tray lower surface support members. 32 to be supported. Thereby, one tray TR is taken out from the tray storage unit 26 (FIG. 5C).

  When one tray TR is taken out from the tray storage unit 26, the control device 19 operates the elevating cylinder 47 to lower the tray placing plate 41 (arrow B5 shown in FIG. 5D). ). As a result, one tray TR is taken out from the tray storage unit 26 (FIG. 5D).

  On the other hand, when the tray TR placed on the tray placement plate 41 is accommodated (collected) in the tray collection unit 27, the control device 19 first moves the horizontal moving body 44 by the horizontal moving conveyor 45 and moves the tray. The tray placement plate 41 on which the TR is placed is positioned directly below the tray collection unit 27. Then, the lifting cylinder 47 is operated to raise the tray mounting plate 41 (arrow C1 shown in FIG. 6A), and the tray TR on the tray mounting plate 41 is accommodated in the tray collection unit 27. The tray TR is superposed from below on the lowermost tray TR in the tray TR (FIG. 6A).

  When the control device 19 superimposes the tray TR on the tray mounting plate 41 on the lowermost tray TR among the trays TR accommodated in the tray collection unit 27, the pair of trays of the tray collection unit 27 is placed. The lower surface support member 32 is operated in the opening direction (arrow C2 shown in FIG. 6B) so that all the stacked trays TR are supported by the tray mounting plate 41 (FIG. 6B). )).

  When all the trays TR that are overlaid are supported by the tray mounting plate 41, the control device 19 activates the elevating cylinder 47 so that the tray mounting plate 41 has a thickness corresponding to one tray TR. Then, the pair of tray lower surface support members 32 are operated in the closing direction (arrow C4 shown in FIG. 6 (d)). As a result, the tray TR on the tray mounting plate 41 is accommodated in the tray collection unit 27 (FIG. 6D).

  In the tray supply device 20 having such a configuration, in order to take out the tray TR in the tray storage unit 26 and supply it to the tray supply position PR1 via the tray standby position PR2, the control device 19 operates the horizontal moving conveyor 45. Then, the tray mounting plate 41 is positioned directly below the tray storage unit 26, and then the lifting cylinder 47 is operated to move the tray mounting plate 41 up and down. Take out (FIG. 7A → FIG. 7B → FIG. 7C).

  When the control device 19 takes out one tray TR from the tray storage unit 26, the horizontal movement conveyor 45 is operated to place the tray placement plate 41 (and hence the tray TR) directly below the tray standby position PR2 (see FIG. 7 (c) → FIG. 7 (d)).

  When the control device 19 positions the tray TR immediately below the tray standby position PR2, the control device 19 widens the distance between the pair of tray movement guides 22 and opens the second tray holding portion 24, and then moves the elevating cylinder 47. The tray mounting plate 41 is operated to move up, and the tray TR positioned immediately below the tray standby position PR2 is pushed up to the tray standby position PR2 (FIG. 7 (d) → FIG. 7 (e)). At this time, the tray TR is pushed up to a position above the upper surface of the tray movement guide 22, and when the tray TR has been pushed up, the interval of the tray movement guide 22 is returned to the reference interval, and then the tray placement plate 41 is lowered. The two ends of the tray TR are supported by the pair of tray movement guides 22 by being moved. As a result, the tray TR is supplied to the tray standby position PR2 (FIG. 7E).

  When the downward movement of the tray mounting plate 41 is completed (FIG. 7 (e) → FIG. 7 (f)), the control device 19 opens the first tray holding part 23 and then operates the slide cylinder 25. Thus, the tray TR on the tray standby position PR2 is slid to the tray supply position PR1 (FIG. 7 (f) → FIG. 7 (g) → FIG. 7 (h)).

  When the control device 19 moves the tray TR to the tray supply position PR1, the control device 19 closes the first tray holding unit 23 and clamps (holds) the tray TR located at the tray supply position PR1. As a result, the tray TR is supplied to the tray supply position PR1 (FIG. 7 (h)).

  In this way, the tray TR is supplied to the tray supply position PR1, but in the component mounting apparatus 1 according to the present embodiment, when the tray supply position PR1 and the tray standby position PR2 are compared, the tray supply position PR1 Is close to the substrate 2 on which the component 4 is to be mounted, the component 4 is picked up by the component mounting means (component reversing unit 17 and component mounting unit 18) in principle from the tray TR positioned at the tray supply position PR1. In other words, when there is no part 4 in the tray TR positioned at the tray supply position PR1 (the tray TR becomes empty), the later-described tray TR is replaced.

  After supplying the tray TR to the tray supply position PR1, the control device 19 moves the horizontal moving body 44 by the horizontal moving conveyor 45 to position the tray mounting plate 41 directly below the tray storage unit 26. Then, the elevating cylinder 47 is operated to move the tray placing plate 41 up and down to take out one tray TR from the tray storage unit 26 (FIG. 8A → FIG. 8B → FIG. 8C). When the control device 19 takes out one tray TR from the tray storage unit 26, the horizontal moving body 44 is moved by the horizontal moving conveyor 45, and the tray placing plate 41 on which the tray TR is placed is placed directly below the tray standby position PR2. (FIG. 8 (c) → FIG. 8 (d)).

  When the control device 19 positions the tray placement plate 41 on which the tray TR is placed directly below the tray standby position PR2, the control device 19 widens the distance between the pair of tray movement guides 22 (in this way, the distance between the tray movement guides 22 is increased). Even if the tray is expanded, the tray TR positioned at the tray supply position PR1 is not dropped because it is held by the first tray holding portion 23), and the second tray holding portion 24 is opened, and the lifting cylinder 47 is opened. Is operated to move the tray mounting plate 41 upward, and the tray TR positioned immediately below the tray standby position PR2 is pushed up to the tray standby position PR2 (FIG. 8 (d) → FIG. 8 (e)). At this time, the tray TR is pushed up to a position above the upper surface of the tray movement guide 22, and when the tray TR has been pushed up, the interval of the tray movement guide 22 is returned to the reference interval, and then the tray placement plate 41 is lowered. The two ends of the tray TR are supported by the pair of tray movement guides 22 by being moved.

  When the downward movement of the tray mounting plate 41 is completed (FIG. 8 (e) → FIG. 8 (f)), the control device 19 closes the second tray holding portion 24 and moves the tray TR positioned at the tray standby position PR2. Clamp (hold). As a result, the tray TR is supplied to the tray standby position PR2 (FIG. 8F).

  The supply of the tray TR to the tray standby position PR2 in a state where the tray TR is held at the tray supply position PR1 is supplied to the tray supply position PR1 by the component mounting means (the component reversing unit 17 and the component mounting unit 18). The component mounting process for picking up the component 4 from the tray TR and mounting it on the substrate 2 positioned by the substrate positioning unit 14 can be performed.

  In order to replace the tray TR, an empty tray TR positioned at the tray supply position PR1 is accommodated (collected) in the tray recovery unit 27, and a new tray TR positioned at the tray standby position PR2 is positioned at the tray supply position PR1. Is done by.

  In order to accommodate the tray TR that has been emptied while being supplied to the tray supply position PR1 in the tray collection unit 27, the control device 19 operates the elevating cylinder 47 and the tray mounting plate 41 is moved to the first tray holding unit 23. Is brought into contact with the lower surface of the empty tray TR. Then, the first tray holding unit 23 is operated in the opening direction and the pair of tray movement guides 22 are opened, and the empty tray TR positioned at the tray supply position PR1 is supported by the tray mounting plate 41 (FIG. 9A). (FIG. 9 (b)).

  After the empty tray TR positioned at the tray supply position PR1 is supported by the tray mounting plate 41, the control device 19 operates the lifting cylinder 47 to move the tray mounting plate 41 downward (FIG. 9 ( b) → FIG. 9 (c)), the horizontally moving conveyor 45 is operated, and the tray mounting plate 41 on which the empty tray TR is placed is positioned directly below the tray collection unit 27 (FIG. 9 (c) → FIG. 9 (d)).

Collecting (receiving) the tray TR from the tray supply position PR1 by moving the tray mounting plate 41 up and down (directly the vertical movement member 43). It consists lifting cylinder 47 as vertical movement driving means for performing.

  In the tray supply device 20 having such a configuration, the tray supply / recovery mechanism 40 is controlled by the control device 19 so that the tray 4 when the component 4 in the tray TR supplied to the tray supply position PR1 is emptied becomes empty. The loading plate 41 is moved up and down below the tray supply position PR1 to collect an empty tray TR on the tray supply position PR1, and the tray TR on the tray standby position PR2 is slid by the slide cylinder 25 and supplied to the tray supply position PR1. After that, the tray mounting plate 41 is moved up and down below the tray standby position PR2 to supply a new tray TR in which the component 4 is stored in the tray standby position PR2.

  In the tray supply device 20 according to the present embodiment, when the component 4 in the tray TR supplied to the tray supply position PR1 becomes empty and the tray TR is replaced, the tray mounting plate 41 is placed at the tray supply position PR1. The tray TR on the tray supply position PR1 is recovered by moving it up and down, and after the tray TR on the tray standby position PR2 is slid by the slide cylinder 25 and supplied to the tray supply position PR1, the tray mounting plate 41 is moved. The tray TR is supplied to the tray standby position PR2 by moving up and down below the tray standby position PR2. At this time, the tray TR is supplied to the tray standby position PR2 at the tray supply position PR1. Since it can be performed while the tray TR is being supplied (that is, while the component mounting operation is being performed), the tray TR Downtime of the component mounting operation caused by the replacement of the TR is essentially requires only the time required to move the tray TR tray standby position PR2 in the tray feeding position PR1 by a slide cylinder 25 (slide). For this reason, there is little tact loss accompanying replacement | exchange of tray TR, and the improvement of productivity of a mounting board | substrate can be aimed at.

  Further, in the tray supply device 20 according to the present embodiment, the tray TR on the tray supply position PR1 is collected and the tray TR is supplied to the tray standby position PR2. The tray supply / recovery mechanism 40 is configured to move horizontally and vertically along the tray movement guide 22 below the movement guide 22, and the tray mounting plate 41 is moved up and down at a plurality of locations. Since it is performed by one driving means (the lifting cylinder 47 which is a vertical movement driving means), the configuration is simple, and the manufacturing cost of the tray supply device 20 and thus the manufacturing substrate can be reduced.

  Note that the movement of the tray TR from the tray standby position PR2 to the tray supply position PR1 is performed at the tray supply position PR1 so that the mounting operation of the component 4 on the substrate 2 is not delayed by the movement operation of the tray TR. Instead of immediately replacing the tray TR positioned at the tray supply position PR1 even when the tray TR is empty, the component 4 is taken out from the tray TR once positioned at the tray standby position PR2 and placed on the substrate 2. Executes a component mounting operation to be mounted, and starts a replacement operation of the substrate 2 on the substrate positioning unit 14 (an operation to unload the substrate 2 on which the component 4 mounting operation has been completed and load and position a new substrate 2). It is preferable to replace the tray TR positioned at the tray supply position PR1 in view of the above timing.

  In the present embodiment, the substrate positioning unit 14 for positioning the substrate 2, the tray supply device 20, and the component 4 is taken out from the tray TR supplied to the tray supply position PR 1 by the tray supply device 20 to position the substrate.
