A tray component feeding device has a loading port for loading the magazine thereinto, and an extraction port for extracting a tray plate of the magazine, which are approximately orthogonal to each other. Further, a component mounting device is provided with the tray component feeding device loaded with the magazine on a lateral side of the component mounting device to which a transfer conveyor for transferring a circuit board extends.

## Background
TECHNICAL FIELD
The present invention relates to a magazine for housing a plurality of trays that accommodate components such as electronic components or optical components, to a tray component feeding device for loading and feeding the magazine, and to a component mounting device for mounting components on a circuit board with use of the tray component feeding device.
BACKGROUND ART
In recent years, diversification of electronic components is increasing forms of housing components (hereinafter referred to as tray components) in a tray. Also, kinds of components to be mounted on a circuit board are increasing. In such circumstance, a component mounting device for mounting components onto a circuit board is required to install a larger number of component feeding devices including tray component feeding devices for feeding the tray components in a limited installation place.
As prior art examples, a tray component feeding device 102 loaded with a magazine 101 shown in FIGS. 12 and 13 is illustrated in FIG. 14, and the tray component feeding device 102 disposed on a rear side of a component mounting device 103 is shown in FIG. 15.
In these figures, a tray plate 105 loaded with components is inserted along a groove 109 provided on each of left and right lateral sides of the magazine 101. The tray plate 105 is regulated in an arrow p direction by a regulation piece 110 provided in the magazine 101, and also regulated in an arrow q direction by a regulation bar 111. On the tray plate 105, there is placed a tray 104 loaded with components. An elevation device 106 of the tray component feeding device 102 moves the magazine 101 in a vertical direction to a level position at which an arbitrary tray plate 105 is extracted, and an extraction device 107 extracts the tray plate 105 in an arrow P direction, for feeding components to the component mounting device 103.
The elevation device 106 moves the magazine 101 in the vertical direction to a removable level, where an opening and closing door 108 provided in the tray component feeding device 102 is opened, so that the magazine 101 or the tray plate 105 put on the elevation device 106 is removed in an arrow Q direction.
As other prior art, an invention disclosed in Japanese Unexamined Patent Publication No. 8-292696 is shown in FIG. 17, and an invention disclosed in Japanese Unexamined Patent Publication No. 5-235587 is shown in FIG. 18.
However, in the above-stated structure, an insertion port and an extraction port for inserting and extracting tray plates into/from the magazine are disposed at positions opposing to each other. Because of this reason, a tray component feeding device incorporating this magazine is disposed on a rear side of a component mounting device (103 as shown in FIG. 15). Consequently, the tray component feeding device 102 is disposed, for example, in place of a tape-type feeding portion 114, which decreases a number of other tape-type feeding portions, thereby preventing increase in number and kinds of available components.
In addition, disposing the tray component feeding device on the rear side of the component mounting device 103 increases a depth dimension of the component mounting device 103. Because of this reason, in structuring a component mounting line including a component mounting device, an installation pitch L between the line and an adjacent component mounting line should be made larger as shown in FIG. 16. If the mounting line is disposed in a horizontal direction of the component mounting device 103, a distance between the component mounting device 103 and an upstream device or a downstream device should be larger for allowing insertion and extraction of a magazine. A distance required in the above case is not generally compensated by a length of a middle conveyor 112 installed for such purpose as maintenance of the component mounting device 103, which as a result makes the mounting line longer.
In both the examples shown in FIGS. 17 and 18 as other prior art, a tray component feeding device 200 is disposed on a lateral side of a component mounting device 201, and insertion and extraction of the trays are performed from a rear side of the component mounting device 201, for implementing a slight decrease in a depth dimension of the component mounting device 201. In both cases, a direction 210 of extracting a tray plate from a magazine 202 housed in the tray component feeding device 200 is orthogonal to a board transfer direction 211 of a circuit board transferring conveyor 203. This makes a depth dimension of the component mounting device 201 longer for a space necessary to extract a tray plate. Therefore, this prior art has had an issue of decreased area productivity as component mounting devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Before description of the present invention proceeds, it is to be noted that like parts are designated by like reference numerals throughout the accompanying drawings.
Hereinbelow, embodiments of the present invention will be described with reference to FIGS. 1 to 12.
FIG. 1 is a perspective view showing a magazine according to a first aspect of the present invention. FIG. 2 is a view of FIG. 1 seen from an arrow A direction. FIG. 3 is a plan view of FIG. 1 seen from a top of the magazine. FIG. 4 is a B side view of FIG. 3. FIG. 5 is a C side view of FIG. 3. FIG. 6 is a D side view of FIG. 3.
In the drawings, a magazine 1 is a hexahedron composed of a top plate 2 and a bottom plate 3 forming a top and bottom, a pillar 4, and two side plates 5 disposed next to each other so as to construct a frame 90 by the pillar 4 and the two side plates 5. Inside each side plate 5, there is fixed a guide 7 provided with a plurality of lateral grooves 6. Groove 6A, same as groove 6 engraved on the guide 7, is given to the pillar 4. In these grooves 6, 6A, a plurality of partition plates 8 are inserted in an arrow j direction, thereby forming a plurality of racks. Insertion and extraction of these partition plates 8 from the grooves 6, 6A are regulated by a regulation plate 9 screwed to the pillar 4.
In each position opposed to the two side plates 5, there are structured an insertion opening portion 10 and an extraction opening portion 11. For the insertion opening portion 10, there is provided an insertion regulation door 13, serving as one example of a tray plate regulation member, on the side plate 5 on a side of the insertion opening portion 10 via spring hinges 12. The insertion regulation door 13 is urged in a direction of closing the insertion opening portion 10 by the spring hinges 12.
Similarly, for the extraction opening portion 11, there is provided an extraction regulation door 15, serving as one example of a tray plate regulation member, on the side plate 5 on a side of the extraction opening portion 11 via spring hinges 14. The extraction regulation door 15 is pressed to a direction of closing the extraction opening portion 11 by the spring hinges 14. Pressing an edge portion 15a of the extraction regulation door 15 releases the extraction regulation door 15.
Description will now be given of operation of the above-structured magazine 1. First, for housing a tray plate 17 that accommodates a tray 18 loaded with components 80 in the magazine 1, the insertion regulation door 13 that closes the insertion opening portion 10 is opened, and the tray plate 17 is slid over the partition plate 8 set inside the magazine 1 and inserted in an arrow j direction.
For extracting the tray plate 17 housed in the magazine 1, the edge portion 15a of the extraction regulation door 15 that closes the extraction opening portion 11 is pressed to open the extraction regulation door 15, by which the tray plate 17 can be extracted in an arrow k direction.
According to the embodiment as described above, the arrow j direction for inserting the tray plate 17 into the magazine 1 can be approximately orthogonal to the arrow k direction for extracting the tray plate 17 from the magazine 1, which makes it possible to decrease a space required for insertion and extraction operations. Therefore, a depth dimension necessary for extraction and insertion may be decreased.
The insertion opening portion 10 and the extraction opening portion 11 are disposed approximately orthogonal to each other. It is understood that although these two opening portions are described as an insertion opening portion and as an extraction opening portion for convenience' sake, each opening portion allows both insertion and extraction operations.
It is also understood that although in the above description, a plurality of racks are provided with use of the side plates 5 and the pillar 4, a total of four pillars may be used, and a regulation plate 9 for adjusting insertion and extraction of the partition plates 8 and the tray plates 7 may be provided in a portion not functioning as a regulation plate opening portion that regulates partition plate 8.
It is further understood that all four directions of the magazine may be regarded as opening portions, and a regulation door for adjusting insertion and extraction of the tray plates 17 may be provided for each of them. This makes it possible to insert and extract the tray plates 17 in any of four directions, thereby enabling use of the magazine as the magazine of FIG. 12 shown as prior art.
Furthermore, the top plate 2 and the bottom plate 3 may be placed in a middle of the plurality of racks.
In a case where it is appropriate that a plurality of the racks have constant intervals, the racks may be fixed to the partition plates 8 or the side plates 5.
Although each partition plate 8 may be attached to a plurality of grooves 6, 6A as described before, it is also possible, depending on a thickness of the tray 18 and a component loaded in the tray 18, not to attach the partition plate 8 to a part of the grooves 6, 6A so as to provide racks with broader intervals (see a lowest rack in FIG. 2). More particularly, if a sum total of (a thickness of the tray plate 17), (a thickness of the partition plate 8), and (a thickness of the tray 18 including a component) is smaller than an inter-groove pitch 19, the partition plates 8 may be inserted into all the grooves 6, 6A of the guide 7 and the pillar 4, and the tray plate 17 may be placed on top of them.
If the sum total described above is larger than the inter-groove pitch 19, the partition plates 8 are not inserted into or are removed from the grooves 6, 6A of a corresponding guide 7 and the pillar 4 (see the lowest rack in FIG. 2), so that an insertion space is secured. Each partition plate 8 is removable by removal of the regulation plate 9 as described above.
Next, description will be given of a tray component feeding device in accordance with a second aspect of the present invention with reference to FIG. 7. In this figure, a lifter 22 as one example of an elevation device is constructed by a driving device such as a motor 22A, and a drive shaft such as a threaded shaft 22B driven by the motor 22A and engaged with a lifter stand 23. Thus, by driving the motor 22A to regularly or reversely rotate the shaft 22B, the lifter 22 moves the lifter stand 23 in an up-and-down direction to an arbitrary position.
The lifter stand 23 is composed of two stages, each of which accommodates magazine 1. The lifter stand 23 is equipped with a stopper 28 for regulating a position of a depth of the magazine 1 placed on one of the stages of the lifter stand 23, and a release plate 29 that serves as one example of a release device and brings into contact with and pushes edge portion 15a of extraction regulation door 15 of the magazine 1 for releasing the extraction regulation door 15. On the lifter stand 23, there are provided toggle clamps 30 for fixing plural magazines 1 (see FIG. 4).
An elevating operation of the lifter stand 23 is safely performed with use of a sensor (unshown) that detects closing of an opening and closing door 24 serving as a member for opening and closing a loading port 95. Through an extraction port 25, there may be inserted or extracted an engaging part 26A of an extraction device 26 which serves as one example of a tray plate extraction device and can engage with an engaging portion 27 of tray plate 17, and a tray plate 17 inside the magazine 1 can be extracted. A magazine stand 32 is located beneath the opening and closing door 24, and may receive the magazine 1 as the magazine 1 is inserted or extracted. A direction of passing a tray plate 17 through the loading port 95 and a direction of passing the tray plate 17 through the extraction port 25 are approximately orthogonal to each other, and the loading port 95 and the extraction port 25 are respectively disposed in directions approximately identical to that of the two opening portions 10 and 15 of the magazine 1.
Following description will be given of an operation of the above-structured tray component feeding device 21. The opening and closing door 24 of the tray component feeding device 21 is opened, and the magazine 1 is slid over the magazine stand 32 with the insertion opening portion 10 of the magazine 1 placed in front, and loaded on the lifter stand 23. On the lifter stand 23, the magazine 1 is pushed forward till the magazine 1 reaches the stopper 28, and fixed by the toggle clamp 30 functioning as a fixing device. Consequently, release plate 29 comes into contact with and pushes the edge portion 15a of the extraction regulation door 15, and thus, the extraction regulation door 15 is opened. Insertion and extraction of released tray plate 17 is regulated by guide plates 31 provided in the tray component feeding device. Because the guide plates 31 are not disposed in a portion of the extraction port 25, the tray plate 17 may be inserted and extracted only through the extraction port 25.
Next, after the opening and closing door 24 is closed, and a detection sensor detects this closing, the lifter 22 moves the lifter stand 23 and stops the lifter stand 23 at an appropriate level for extracting a selected tray plate 17.
The engaging part 26A of the extraction device 26 catches the engaging portion 27 of the tray plate 17, and extracts the tray plate 17 through the extraction opening portion 11 of the magazine 1 and through the extraction port 25 of the tray component feeding device 21. Upon completion of component supply, the extraction device 26 returns the tray plate 17 to an interior of the magazine 1 in reverse order of the above.
According to the embodiment as described above, a direction of loading the tray plate 17 and the magazine 1 in the tray component feeding device is made approximately orthogonal to a direction of extracting the tray plate 17 from the magazine 1, thereby enabling implementation of a tray component feeding device with a decreased depth dimension.
Further, description will be given of a component mounting device in accordance with a third aspect of the present invention with reference to FIGS. 8 and 9. In these figures, tray component feeding device 21 is disposed on a lateral side 34s of a component mounting device 34. The component mounting device 34 is composed of a loader 39 that is a transfer conveyor for transferring a circuit board 35 to an interior of the component mounting device 34, a tape component feeding device 36 for feeding taped components, an unloader 41 that is a transfer conveyor for transferring a component-mounted circuit board 35 out of the component mounting device 34, a transfer head 43 for placing components on tray plate 17 extracted from the tray component feeding device 21 onto a shuttle conveyor 42, and an XY robot 38 for freely moving a head unit 33 that sucks electric components from the component feeding device 36 or the shuttle conveyor 42 and mounts the components onto a board 35 in an XY plane.
It is noted that suction postures of components held by the head unit 33 are recognized by a component recognizing camera 44 for implementation of posture compensation, by which the components are accurately mounted in specified mounting positions of the board 35.
Operation of the above-structured component mounting device 34 will be described hereinafter. The magazine 1 is loaded into the tray component feeding device 21 in a J direction, that is a direction orthogonal to a board transfer direction of the transfer conveyors 39 and 41, and a tray plate 17 selected from the magazine 1 is extracted through the extraction port 25 of the tray component feeding device 21 in a K direction by the extraction device 26, while the transfer head 43 transfers components on the tray 18 to a top of the shuttle conveyor 42. The tray plate 17 taken into the component mounting device 34 is located along the board transfer direction of the transfer conveyor 39.
The components on the shuttle conveyor 42 are conveyed to an end position of the shuttle conveyor 42, where each of the components is picked up by the head unit 33, and subjected to posture compensation by the component recognizing camera 44. After that, this component is mounted onto the board 35 by the head portion 33. It is also possible to directly pick up, by the head unit 33, a component on the tray 18 not through the shuttle conveyor 42.
Accordingly, in a case where replacement of the tray plate 17 is desired because all the components on the tray plate 17 are no longer fed to the component mounting device 34, the components need replacement with other components, or because of other reasons, the tray plate 17 taken into the component mounting device 34 is returned to the interior of the magazine 1, and a new tray plate 17 is extracted therefrom. The tray plate 17 may be inserted or extracted into/from the magazine 1 in a state that the magazine 1 is loaded onto the lifter stand 23.
According to the embodiment as described above, the tray component feeding device may be disposed with a decreased depth dimension of the component mounting device, thereby enabling implementation of a component mounting device with good area productivity.
Accordingly, in structuring a component mounting line including the component mounting device as shown in FIG. 10, an installation pitch L between the line and other adjacent component mounting lines can be decreased.
Although in the above description, the tray component feeding device is disposed on the right lateral side of the component mounting device, providing the tray component feeding device symmetric to the tray component feeding device of FIG. 7 makes it possible to dispose the tray component feeding device on the left lateral side of the component mounting device.
Furthermore, the tray component feeding device may be disposed at a rear end of the component mounting device as shown in FIG. 11. In such structure, a direction of inserting and extracting a magazine into/from the tray component feeding device is parallel to a board transfer direction of the circuit board transfer conveyor, thereby enabling a decreased depth dimension of the component mounting device.
As described above, the magazine according to the present invention is provided with two opening portions that enable insertion and extraction of a tray and are approximately orthogonal to each other, and a regulation member for regulating insertion and extraction of the tray from the opening portions, thereby implementing an effect of decreasing a depth dimension necessary for insertion and extraction of the tray into/from the magazine.
Furthermore, the tray component feeding device according to the present invention has a loading port for loading a magazine and an extraction port for extracting a tray plate of the magazine, which are approximately orthogonal to each other, thereby providing an effect of implementing the tray component feeding device with a decreased depth dimension.
In addition, the component mounting device according to the present invention is provided with a tray component feeding device loaded with a magazine on a lateral side of the component mounting device to which a transfer conveyor for transferring a circuit board extends, thereby providing an effect of implementing the component mounting device with good area productivity.
Although the present invention has been fully described in connection with preferred embodiments thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications are apparent to those skilled in the art. Such changes and modifications are to be understood as included within the scope of the present invention as defined by the appended claims unless they depart therefrom.
