Description

[Technical Field]

[0001] The present specification relates to a tray-type component supplying device that supplies components using trays. [Background technology]

[0002] Substrate-related processing machines that produce substrate products with a large number of components mounted thereon include solder printing machines, component placement machines, reflow machines, and substrate inspection machines. It is common for these substrate-related processing machines to be arranged in a row to form a substrate production line. Among these, component placement machines may be equipped with a component supply device that uses trays on which components are arranged. Generally, tray-type component supply devices hold multiple trays and supply multiple types of components by replacing the trays when components are consumed. Technical examples of this type of tray-type component supply device are disclosed in Patent Documents 1 and 2.

[0003] Patent Document 1 discloses a component mounting system that supplies tray components using a supply unit mounted on a traveling body that travels between a component storage facility and multiple component mounting machines. In this system, a tray feed mechanism transfers trays on which tray components are arranged between a magazine on the traveling body and a magazine on the component mounting machine. This system is said to enable automatic supply and collection of trays, enabling automatic and efficient supply of required parts.

[0004] Furthermore, the tip supply device in Patent Document 2 includes a magazine that stores multiple trays arranged vertically, a holder that suspends and holds the magazine, and means for moving the holder up and down, and a space below the magazine is secured for a cart to move in and out. This allows an operator to use the cart to replace the magazine. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] International Publication No. 2014 / 010084 [Patent Document 2] Japanese Patent Application Publication No. 7-17602 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology of Patent Document 1 automatically transfers trays one by one, and cannot replace multiple trays housed in a magazine all at once. Therefore, when replacing multiple trays, such as during a setup change to change the type of substrate being produced, the replacement operation becomes complicated and takes a long time. In contrast, the technology of Patent Document 2 can replace magazines all at once, but since the replacement work is done manually, automation has not been achieved.

[0007] The present specification has an object to provide a tray-type component supplying device that can automatically replace a magazine that accommodates a plurality of trays. [Means for solving the problem]

[0008] This specification discloses a tray-type component supply device comprising: an apparatus main body; a magazine that is detachably held in the apparatus main body and that stores a plurality of trays, on which a plurality of components are arranged, arranged one above the other; a shuttle mechanism that pulls out any one of the trays from the magazine to enable the components to be supplied; an elevating mechanism that raises and lowers the magazine or the shuttle mechanism to select the tray to be pulled out by the shuttle mechanism; and an automatic exchange unit that exchanges the magazine that is retrieved from the apparatus main body with the magazine that is replenished to the apparatus main body. [Effects of the Invention]

[0009] According to the tray-type component supply device disclosed in this specification, the automatic replacement unit replaces the magazine retrieved from the device main body with the magazine replenished to the device main body, thereby enabling automatic replacement of magazines containing multiple trays.

[0011] 1. Configuration of the magazines (3A, 3M) of the tray-type component supply device 1 of the embodiment The configuration of a tray-type component supply device 1 according to an embodiment will be described with reference to the device configuration diagrams of Figures 1 to 3 and the control configuration diagrams of Figures 4 and 5. In the plan view of Figure 1, the front, rear, left, and right directions common to the component mounting device 9 and the tray-type component supply device 1 are defined for convenience. The outline of the component mounting device 9 is shown in Figures 1 to 3, and the mounting head 91 and suction nozzle 92 provided on the component mounting device 9 are shown in Figures 2 and 3.

[0012] The tray-type component supply device 1 is mounted in front of the component mounting machine 9. The tray-type component supply device 1 supplies components to the component mounting machine 9 using trays Ty on which a plurality of components are arranged. The tray-type component supply device 1 is composed of a device main body 2, an automatic magazine 3A, a manual magazine 3M, a shuttle mechanism 4, an elevating mechanism 5 (see FIG. 4), an automatic magazine exchange unit 6A, a feeder device 3F, an automatic feeder exchange unit 6F, two height detection units 7A and 7F, a height adjustment unit 7J, and a control device 8 (see FIGS. 4 and 5).

[0013] The device main body 2 is composed of a main body case 21, an insertion section 25, a lower support table 26, and an upper support table 28. The main body case 21 is formed in the shape of a vertically long rectangular parallelepiped. The main body case 21 is disposed adjacent to the front edge of the component mounting machine 9. An automatic change window 22 larger than the size of the automatic magazine 3A is opened toward the bottom of the front of the main body case 21. An openable maintenance door 23 larger than the size of the manual magazine 3M is provided toward the top of the front of the main body case 21. A drawer window 24 larger than the size of the tray Ty is opened at approximately the middle height of the rear of the main body case 21.

[0014] The insertion section 25 is provided on the rear surface of the main body case 21. The insertion section 25 is inserted into the component mounting device 9. The insertion section 25 is made up of a shuttle support section 251 and a feeder holding section 252. The shuttle support section 251 is a horizontally disposed rectangular plate-like member. The shuttle support section 251 is disposed to the left of the component mounting device 9 and at a position slightly lower than the drawer window 24. The feeder holding section 252 is a horizontally disposed rectangular plate-like member. The feeder holding section 252 is disposed to the right of the component mounting device 9 and at a position higher than the shuttle support section 251.

[0015] The lower holding table 26 is arranged inside the main body case 21 so as to be able to move up and down. The lower holding table 26 is a rectangular, thick plate-shaped member. The lower holding table 26 has transfer rollers 27, multiple of which are arranged in a row in the front-to-back and left-to-right directions. The upper holding table 28 is arranged above the lower holding table 26 inside the main body case 21 so as to be able to move up and down. The upper holding table 28 is a rectangular, thick plate-shaped member.

[0016] The automatic magazine 3A is formed in a box shape with a height less than half that of the main body case 21. The automatic magazine 3A is detachably held on the upper side of the lower holder 26. The weight of the held automatic magazine 3A is supported by transfer rollers 27. The transfer rollers 27 are one embodiment of a main body magazine drive unit that rotates with the automatic magazine 3A placed on it to transfer the automatic magazine 3A.

[0017] A plurality of holding shelves 31 are arranged vertically inside the automatic magazine 3A. Each holding shelf 31 stores a tray Ty. A plurality of parts are arranged in a two-dimensional grid pattern on each tray Ty. The rear of the automatic magazine 3A is open, allowing the tray Ty to be pulled out rearward. Note that a tray pallet (not shown) on which the tray Ty is placed may be stored in each holding shelf 31, allowing the tray Ty and the tray pallet to be pulled out together.

[0018] The height position of the automatic magazine 3A is adjusted so that it faces the automatic change window 22. The automatic magazine 3A is transferred to the front side of the lower support base 26 by the reverse rotation of the transfer rollers 27, and passes through the automatic change window 22 toward the front. This allows the automatic magazine 3A to be removed from the device main body 2. Furthermore, the forward rotation of the transfer rollers 27 transfers the automatic magazine 3A from the front, passing through the automatic change window 22 to the lower support base 26. This allows the automatic magazine 3A to be replenished into the device main body 2.

[0019] Like the automatic magazine 3A, the manual magazine 3M is formed in a box shape with a height less than half that of the main body case 21. The manual magazine 3M is held on the upper side of the upper holder 28. Inside the manual magazine 3M, multiple holding shelves 33 are arranged vertically. Each holding shelf 33 stores a tray Ty. Each tray Ty has multiple parts arranged in a two-dimensional lattice pattern. The manual magazine 3M and the automatic magazine 3A may have the same shape.

[0020] The rear of the manual magazine 3M is open, allowing the tray Ty to be pulled out rearward. The height position of the manual magazine 3M can be adjusted so that it faces the maintenance door 23. The front of the manual magazine 3M is open, and maintenance is performed through the maintenance door 23. For example, an operator can replace the tray Ty through the maintenance door 23 to replenish parts or inspect the inside of the manual magazine 3M. Furthermore, the operator can also replace the entire manual magazine 3M.

[0021] The lifting mechanism 5 independently lifts and lowers the automatic magazine 3A and the manual magazine 3M. The lifting mechanism 5 is controlled to avoid collision between the automatic magazine 3A and the manual magazine 3M. The lifting mechanism 5 plays a role in selecting the tray Ty to be drawn out through the drawer window 24. As shown in FIG. 4, the lifting mechanism 5 includes a first lifting mechanism 51 that drives the automatic magazine 3A up and down together with the lower holder 26, and a second lifting mechanism 52 that drives the manual magazine 3M up and down together with the upper holder 28. An example of the first lifting mechanism 51 and the second lifting mechanism 52 is a ball screw feed mechanism driven by a motor.

[0022] The shuttle mechanism 4 is provided above the shuttle support portion 251. The shuttle mechanism 4 can pull out any tray Ty from the automatic magazine 3A or the manual magazine 3M to supply components. The shuttle mechanism 4 has a locking portion that locks with a locking portion provided on the tray Ty or the tray pallet to pull the tray out of the main body case 21 or return it to the main body case 21. In FIG. 2, the top tray Ty of the manual magazine 3M is pulled out. The suction nozzle 92 descends toward the pulled tray Ty and sucks up the component when negative pressure is applied.

[0023] The automatic magazine exchange unit 6A exchanges an automatic magazine 3A to be retrieved from the device main body 2 with an automatic magazine 3A to be replenished to the device main body 2. As shown in FIG. 2, the automatic magazine exchange unit 6A is equipped with running wheels 6A1 that correspond to a running unit and is configured in the form of an unmanned guided vehicle. The running wheels 6A1 run along a running path 62 that continues to the parts warehouse 63. This allows the automatic magazine exchange unit 6A to travel back and forth between the parts warehouse 63 and the component mounting machine 9. Position markers for controlling the running position of the automatic magazine exchange unit 6A are appropriately placed near the running path 62. The automatic magazine exchange unit 6A detects the position markers and recognizes its current position.

[0024] Two storage units 6A5 for storing automatic magazines 3A are provided above the automatic magazine changing unit 6A. An automatic magazine 3A to be replenished is placed in one of the storage units 6A5. An automatic magazine 3A to be retrieved is placed in the other storage unit 6A5. In FIG. 1, the automatic magazine 3A to be replenished is shown in solid lines, and the automatic magazine 3A to be retrieved is shown in dashed lines. However, the automatic magazine changing unit 6A may run with two automatic magazines 3A stored therein, or may run without any automatic magazines 3A stored therein.

[0025] The storage section 6A5 has a plurality of transfer rollers 6A6 arranged in a row in the front-to-back and left-to-right directions. The weight of the automatic magazine 3A stored in the storage section 6A5 is supported by the transfer rollers 6A6. The transfer rollers 6A6 are one embodiment of a replacement magazine drive unit that rotates with the automatic magazine 3A placed on it to transfer the automatic magazine 3A. The transfer rollers 6A6 work together with the transfer rollers 27 on the device main body 2 side to transfer the automatic magazine 3A.

[0026] More specifically, prior to transfer, the transfer roller 6A6 and the transfer roller 27 are aligned in the front-to-rear direction. The automatic magazine 3A to be replenished is moved rearward from the storage section 6A5 by the forward rotation of the transfer roller 6A6. The automatic magazine 3A to be replenished is then replenished through the automatic exchange window 22 into the device body 2 by the forward rotation of the transfer roller 27. The automatic magazine 3A to be collected is then removed from the device body 2 through the automatic exchange window 22 by the reverse rotation of the transfer roller 27. The automatic magazine 3A to be collected is then stored in the storage section 6A5 by the reverse rotation of the transfer roller 6A6.

[0027] The height relationship between the device body 2 and the automatic magazine exchange unit 6A may change due to the automatic magazine exchange unit 6A traveling back and forth between the component warehouse 63 and the component mounter 9. For example, the height position of the storage unit 6A5 may change due to changes in the conditions of the travel path 62 and the floor surface F, or due to individual differences between the multiple automatic magazine exchange units 6A. To address this, a height detection unit 7A is provided, and the first lifting mechanism 51 functions as a height adjustment unit.

[0028] The height detection unit 7A is disposed below the automatic exchange window 22 on the front surface of the main body case 21. The height detection unit 7A detects the height of the storage unit 6A5 that it is generally directly facing. An example of the height detection unit 7A is a detection type sensor that reads a linear scale attached to the storage unit 6A5 so as to extend in the vertical direction, but is not limited to this.

[0029] The first lifting mechanism 51, which corresponds to the height adjustment unit, adjusts the height of the automatic magazine 3A to be retrieved, i.e., the height position of the lower holder 26, based on the detected height of the storage unit 6A5. As a result, the height of the bottom end of the automatic magazine 3A to be retrieved coincides with the height of the top of the storage unit 6A5. Furthermore, the first lifting mechanism 51 adjusts its own height, i.e., the height position of the lower holder 26, to match the height of the automatic magazine 3A to be replenished, based on the detected height of the storage unit 6A5. As a result, the height of the bottom end of the automatic magazine 3A to be replenished coincides with the height of the top of the lower holder 26. Therefore, there is no difference in height when transferring the automatic magazine 3A, achieving a smooth replacement operation.

[0030] 2. Configuration of the feeder device 3F of the tray-type component supply device 1 The feeder device 3F is disposed above the feeder holding section 252 and is positioned by a locking mechanism (not shown). In this embodiment, the feeder device 3F is composed of a feeder pallet (not shown) and multiple feeders. More specifically, the plate-shaped feeder pallet has multiple slots extending in the front-to-rear direction formed therein. A feeder is fitted into each slot. Each feeder supplies components by unwinding a carrier tape that holds multiple components. However, the present invention is not limited to this, and the feeder device 3F may also be composed of a single feeder.

[0031] Feeder holding section 252 has a plurality of transfer rollers 29 arranged in a row in the front-to-back and left-to-right directions. The weight of feeder device 3F held in feeder holding section 252 is supported by transfer rollers 29. Transfer roller 29 is one embodiment of a main body side feeder drive section that rotates with feeder device 3F placed on it to transfer feeder device 3F.

[0032] The automatic feeder exchange unit 6F exchanges the feeder device 3F that is collected from the main body 2 with the feeder device 3F that is replenished to the main body 2. As shown in FIG. 3, the automatic feeder exchange unit 6F is equipped with running wheels 6F1 that correspond to a running unit and is configured in the form of an automated guided vehicle. The running wheels 6F1 run along a running path 62 that continues to the parts warehouse 63, so that the automatic feeder exchange unit 6F travels back and forth between the parts warehouse 63 and the component mounting machine 9. The automatic feeder exchange unit 6F may have the same shape as the automatic magazine exchange unit 6A or a different shape.

[0033] The parts warehouse 63 stores at least one of the feeder devices 3F and carrier tapes. Furthermore, the parts warehouse 63 stores at least one of the automatic magazines 3A and trays Ty. Therefore, an operator can perform preparation work for the automatic magazines 3A and feeder devices 3F to be replenished inside the parts warehouse 63. The automatic feeder exchange unit 6F transports the prepared feeder devices 3F and replenishes them in the device main body 2. The automatic feeder exchange unit 6F also transports the collected feeder devices 3F and takes them back to the parts warehouse 63.

[0034] Similarly, automatic magazine exchange unit 6A transports prepared automatic magazines 3A and supplies them to device main body 2. Automatic magazine exchange unit 6A also transports collected automatic magazines 3A and takes them back to parts warehouse 63. Note that parts warehouse 63 and travel path 62 are common to automatic feeder exchange unit 6F and automatic magazine exchange unit 6A, but they may also be provided separately.

[0035] Two storage units 6F5 for accommodating feeder devices 3F are provided above the automatic feeder exchange unit 6F. A feeder device 3F to be replenished is placed in one of the storage units 6F5. A feeder device 3F to be retrieved is placed in the other storage unit 6F5. In FIG. 1, the feeder device 3F to be replenished is indicated by a solid line, and the feeder device 3F to be retrieved is indicated by a dashed line. However, the automatic feeder exchange unit 6F may run accommodating two feeder devices 3F, or may run without accommodating any feeder device 3F.

[0036] The storage section 6F5 has transfer rollers 6F6 arranged in a row in the front-to-back and left-to-right directions. The weight of the feeder device 3F stored in the storage section 6F5 is supported by the transfer rollers 6F6. The transfer rollers 6F6 are one embodiment of a replacement-side feeder drive unit that rotates with the feeder device 3F placed on it to transfer the feeder device 3F. The transfer rollers 6F6 work together with the transfer rollers 29 on the device main body 2 and the transfer rollers 73 of the height adjustment unit 7J, which will be described later, to transfer the feeder device 3F.

[0037] The height relationship between the device body 2 and the automatic feeder exchange unit 6F may change due to the automatic feeder exchange unit 6F traveling back and forth between the component warehouse 63 and the component mounting machine 9. For example, the height position of the storage unit 6F5 may change due to changes in the conditions of the travel path 62 and the floor surface F, or due to individual differences among the multiple automatic feeder exchange units 6F. To address this issue, a height detection unit 7F and a height adjustment unit 7J are provided.

[0038] The height adjustment unit 7J is disposed between the feeder automatic exchange unit 6F and the device main body 2. The height adjustment unit 7J consists of a main body 71 and an intermediate storage unit 72 that moves up and down relative to the main body 71. The height position of the intermediate storage unit 72 roughly matches the height position of the feeder holding unit 252 and the height position of the storage unit 6F5 of the feeder automatic exchange unit 6F, and an adjustment range is set in both the vertical and horizontal directions. The intermediate storage unit 72 temporarily stores the feeder device 3F that passes through in the forward and backward directions.

[0039] The intermediate storage section 72 has a plurality of transfer rollers 73 arranged in a row in the front-to-back and left-to-right directions. The weight of the feeder device 3F stored in the intermediate storage section 72 is supported by the transfer rollers 73. The transfer rollers 73 are one embodiment of an intermediate feeder drive section that rotates with the feeder device 3F placed on them to transfer the feeder device 3F.

[0040] The height detection unit 7F is disposed in front of the intermediate storage unit 72. The height detection unit 7F detects the height of the storage unit 6F5 that it is generally directly facing. The height detection unit 7F may use the same detection method as the height detection unit 7A of the automatic magazine exchange unit 6A, or a different detection method.

[0041] The height adjustment unit 7J raises and lowers the intermediate storage unit 72 based on the detected height of the storage unit 6F5, thereby raising and lowering the feeder device 3F. This eliminates any difference in height when the feeder device 3F is transferred between the storage unit 6F5 and the intermediate storage unit 72. Furthermore, this eliminates any difference in height when the feeder device 3F is transferred between the intermediate storage unit 72 and the feeder holding unit 252. This allows for smooth replacement of the feeder device 3F.

[0042] Prior to the transfer of the feeder device 3F, the transfer rollers 6F6, 73, and 29 are aligned linearly in the front-to-rear direction. The feeder device 3F to be replenished is transferred from the automatic feeder exchange unit 6F to the device body 2 via the height adjustment unit 7J by the forward rotation of the transfer rollers 6F6, 73, and 29. The locking mechanism of the feeder device 3F to be collected is first released. Thereafter, the feeder device 3F to be collected is transferred from the device body 2 to the automatic feeder exchange unit 6F via the height adjustment unit 7J by the reverse rotation of the transfer rollers 29, 73, and 6F6.

[0043] 3. Control configuration of tray-type component supply device 1 Next, the control configuration of the tray-type component supply device 1 will be described with reference to Figs. 4 and 5. The control device 8 is configured using a computer device having a CPU and operating on software. The control device 8 is provided in the device main body 2, and its installation location is not particularly restricted. As shown in Fig. 4, the control device 8 controls the first lifting mechanism 51 and the second lifting mechanism 52 of the lifting mechanism 5 to select the tray Ty, and controls the shuttle mechanism 4 to insert or remove the tray Ty.

[0044] The control device 8 includes a main body control unit 81 that controls the replacement of the automatic magazine 3A. The main body control unit 81 acquires the detection result from the height detection unit 7A. Furthermore, the main body control unit 81 controls the forward rotation, reverse rotation, and stop of the transfer roller 27. The main body control unit 81 also controls the operation of the first lifting mechanism 51, which serves as a height adjustment unit.

[0045] Meanwhile, the automatic magazine exchange unit 6A has an exchange-side control unit 82 that controls the exchange of the automatic magazine 3A. The exchange-side control unit 82 controls the running wheels 6A1 to position the automatic magazine exchange unit 6A at a predetermined exchange position. There are two exchange positions, where one of the storage units 6A5 directly faces the automatic exchange window 22. The exchange-side control unit 82 also controls the transfer roller 6A6 to switch between forward rotation, reverse rotation, and stop.

[0046] The main body control unit 81 and the replacement control unit 82 exchange control information CA related to the transfer of the automatic magazine 3A via a wireless communication unit (not shown). The control information CA sent from the replacement control unit 82 to the main body control unit 81 includes information that the automatic magazine replacement unit 6A has been positioned at the replacement position, information that the feeding of the replenishment automatic magazine 3A has started, and information that the receipt of the collection automatic magazine 3A has been completed.

[0047] Furthermore, the control information CA sent from the main body control unit 81 to the replacement control unit 82 includes information that the first lifting mechanism 51 has finished adjusting the height position of the lower support table 26, information that the feeding of the automatic magazine 3A to be collected has started, and information that the reception of the automatic magazine 3A to be replenished has finished. The main body control unit 81 and the replacement control unit 82 refer to the control information CA exchanged between them and jointly control the replacement operation of the automatic magazine 3A.

[0048] Furthermore, as shown in FIG. 5, the control device 8 includes a main body side control unit 85 that controls replacement of the feeder device 3F. The main body side control unit 85 acquires the detection result from the height detection unit 7F. Furthermore, the main body side control unit 85 controls the forward rotation, reverse rotation, and stop of the transfer roller 29 and the transfer roller 73. The main body side control unit 85 also controls the height position of the intermediate storage unit 72 of the height adjustment unit 7J.

[0049] Meanwhile, the automatic feeder exchange unit 6F has an exchange-side control unit 86 that controls the exchange of the feeder device 3F. The exchange-side control unit 86 controls the running wheels 6F1 to position the automatic feeder exchange unit 6F at a predetermined exchange position. There are two exchange positions, where one of the storage units 6F5 directly faces the feeder holding unit 252. The exchange-side control unit 86 also controls the transfer roller 6F6 to switch between forward rotation, reverse rotation, and stop.

[0050] The main body side control unit 85 and the exchange side control unit 86 exchange control information CF related to the transfer of the feeder device 3F via a wireless communication unit (not shown). The control information CF sent from the exchange side control unit 86 to the main body side control unit 85 includes information that the automatic feeder exchange unit 6F has been positioned at the exchange position, information that the feeder device 3F to be replenished has started to be sent out, and information that the feeder device 3F to be collected has finished being received.

[0051] The control information CF sent from the main body side control unit 85 to the exchange side control unit 86 includes information that adjustment of the height position of the height adjustment unit 7J has been completed, information that the feeder device 3F to be collected has started to send out, information that the feeder device 3F to be replenished has finished receiving, etc. The main body side control unit 85 and the exchange side control unit 86 refer to the control information CF exchanged between them and jointly control the exchange operation of the feeder device 3F.

[0052] 4. Operation of tray-type component supply device 1 Next, the operation of the tray-type component supply device 1 when replacing the automatic magazine 3A will be described with reference to the operation flow in Fig. 6. Prior to the execution of the operation flow, the automatic magazine 3A to be replenished is stored in one storage section 6A5 of the automatic magazine exchange unit 6A, and the other storage section 6A5 is left empty. Then, the automatic magazine exchange unit 6A travels to a position near the component mounter 9.

[0053] 6, the automatic magazine exchange unit 6A is positioned at the first exchange position. At this time, the empty storage unit 6A5 faces the automatic exchange window 22. In the next step S2, the height detection unit 7A detects the exchange height at which the empty storage unit 6A5 retrieves the automatic magazine 3A. Furthermore, the first lifting mechanism 51 adjusts the height of the automatic magazine 3A to be retrieved based on the detected exchange height of the storage unit 6A5. In the next step S3, under the joint control of the main body-side control unit 81 and the exchange-side control unit 82, the transfer roller 27 and the transfer roller 6A6 operate in cooperation to retrieve the automatic magazine 3A that was stored in the device main body 2 into the empty storage unit 6A5.

[0054] In the next step S4, the automatic magazine exchange unit 6A is positioned at the second exchange position. At this time, the storage unit 6A5 containing the automatic magazine 3A to be replenished faces the automatic exchange window 22. In the next step S5, the main body side control unit 81 and the exchange side control unit 82 jointly control the transfer rollers 6A6 and 27 to operate together, and the automatic magazine 3A from the storage unit 6A5 is replenished to the device main body 2.

[0055] In the replacement operation of the feeder device 3F, the collection is performed first, followed by the supply, and a detailed description thereof will be omitted. However, the height adjustment unit 7J adjusts the height of the feeder device 3F to be transferred during both collection and supply.

[0056] According to the embodiment of the tray-type component supply device 1, the automatic magazine exchange unit 6A exchanges the automatic magazine 3A collected from the device main body 2 with the automatic magazine 3A replenished to the device main body 2, so that the automatic magazine 3A containing multiple trays Ty can be exchanged automatically.

[0057] Furthermore, since the manual magazine 3M is used in combination, components can be supplied from the manual magazine 3M when the automatic magazine 3A is replaced, and the mounting operation of the component mounting machine 9 is not interrupted. Furthermore, since the automatic magazine change unit 6A travels to the parts warehouse 63, it contributes to labor savings and automation of the parts warehouse 63. In addition, since the tray-type component supply device 1 is equipped with the automatic feeder change unit 6F, replacement of the feeder device 3F can also be automated.

[0058] 5. Applications and Modifications of the Embodiments The height detection units (7A, 7F) and the height adjustment unit 7J may be provided on the side of the automatic magazine exchange unit 6A or the automatic feeder exchange unit 6F. It is also possible to adopt a configuration in which the feeder device 3F, the automatic feeder exchange unit 6F, and the height adjustment unit 7J are omitted. Furthermore, the shuttle mechanism 4 may be used to exchange trays Ty between the automatic magazine 3A and the manual magazine 3M. This reduces the operator's workload when using the manual magazine 3M.

[0059] Also, it is possible to have only the automatic magazine 3A without providing the manual magazine 3M. In this embodiment, the height position of the automatic magazine 3A may be kept constant, and the lifting mechanism 5 may drive the shuttle mechanism 4 up and down to select the tray Ty to be extracted. Furthermore, it is also possible to provide transfer rollers 27 on the upper holder 28 and the lower holder 26, and to configure the automatic magazine exchange unit 6A to automatically exchange the automatic magazine 3A for either the upper holder 28 or the lower holder 26.

[0060] Furthermore, the automatic magazine exchange unit 6A and the automatic feeder exchange unit 6F do not need to be in the form of an automated guided vehicle, but may be stationary. Even if they are in the form of automated guided vehicles, they can be configured so that fluctuations in the height position of the storage units (6A5, 6F5) are negligible. In these configurations, the height detection units (7A, 7F) and the height adjustment unit 7J are unnecessary. The embodiments can be applied and modified in various other ways.
