In this case, the door 67 of the tray magazine 45 is opened by the magazine opening / closing drive unit 65 and the tray plate clamp unit 75 of the tray plate discharge unit 61 is moved, so that the tray plate 47 in the tray plate mounting unit 63 is moved. Is sent into the tray magazine 45. That is, when the skip switch 109 is pressed, the tray plate discharge unit 61 returns the tray plate 47 drawn out to the tray plate mounting unit 63 to the tray magazine 45 as it is, and restarts the component supply operation by the component supply device 13. Let it. In this case, the lit component replacement switch 105 is also turned off.
[0062]
Further, as described above, when the operator presses the component replacement switch 105 or the skip switch 109, the tray plate discharge unit 61 causes the tray plate 47 of the tray pallet 49 to be replaced or the tray plate of the tray pallet 49 that has not been replaced. 47 can be returned to the tray magazine 45 on the side of the lifter 41, but the cancel switch 107 can also be pressed during the operation. When the operator presses the cancel switch 107, the operation of returning the tray plate 47 to the tray magazine 45 is interrupted, and the tray plate 47 is pulled back to the tray plate mounting portion 63 to stop the operation.
[0063]
Note that the component supply device 13 temporarily stops the supply operation of the component 19 during the operation of discharging or returning the tray plate 47 by the tray plate discharge portion 61. The mounting operation of the supplied component 19 is continued by a component supply cassette or the like mounted on the component supply unit 32 as a supply unit.
[0064]
If there is a request to supply the parts 19 during the discharging operation of the tray plate 47, the parts are supplied with priority. Here, if there is a component supply request before the lifting / lowering operation of the tray magazine 45 by the lifter 41 in the discharging operation, the discharging operation of the tray plate 47 is interrupted, and the component supply is preferentially performed.
[0065]
In addition, if there is a component supply request from the component mounting apparatus 100 after the lifting operation of the tray magazine 45 by the lifter 41 in the discharging operation is started, the component supply is performed when the tray plate 47 is pulled out to the tray plate mounting portion 63. Let it resume. In this case, the component supply operation is temporarily interrupted in the component supply device 13, but the control unit 111 automatically switches to a program for mounting the component 19 supplied from the component supply unit 32 and performs the mounting operation. Let it continue.
[0066]
Further, in the component supply device 13, when information about the out-of-component on the tray pallet 49 of the tray plate 47 and the position information of the tray plate 47 in which the out-of-component has occurred are input to the control unit 111, the control unit 111 causes The status of the tray pallet 49 and the parts 19 (positional information and out-of-parts information) are displayed. The control unit 111 receives information on the presence / absence of the tray plate 47 in the tray plate mounting unit 63 and information on the out-of-parts together with the position information of the tray plate 47 in which the out-of-parts occurred.
[0067]
Then, based on the information, the control unit 111 displays on the display unit 103 of the operation panel 101 of the tray plate discharge unit 61 or turns on the display lamp 35 of the mounting apparatus main body 11, thereby giving the operator a tray pallet. The erroneous replacement of 49 or the setting error is notified, or the shortage of parts is notified soon, so that it can be easily determined.
[0068]
Further, when replacing the tray pallet 49, the worker inputs the type and position of the replaced tray pallet 49 or the component information such as the type, part number, name or remaining number of the component 19 into the input unit 33 of the component mounting apparatus 100. Enter from. In this way, the main control unit 10 compares the input component information with the component information stored in the storage memory 115 in advance, determines whether or not the component information matches, and when the component information does not match, It is determined whether or not the input component information can be replaced. When the input component information and the component information stored in the storage memory 115 of the component supply device 13 do not match or do not match and cannot be replaced, the control unit 10 displays the component mounting device 100. By displaying the information on the device 34 or turning on the indicator light 35, a warning is given to that effect.
[0069]
In the component supply device 13, when the tray plate 47 discharged to the tray plate mounting portion 63 due to a component shortage is returned without replacing the tray pallet 49, the device enters a state of waiting for replenishment of the component. Further, even when another tray plate has the same part as a substitute, if a part of the tray plate of the same part is already gone, the part is in a state of waiting for replenishment.
[0070]
Also, the component supply device 13 replaces the tray pallet 49 of the tray plate 47 in the tray plate discharge unit 61 even when the mounting of the circuit board 15 of the type currently being produced is completed and the product is shifted to the next production type. Leakage, incorrect setting of the tray plate 47, interference with the tray plate 47 of the tray magazine 45, and the like, and reduction in workability due to batch replacement of the tray plate 47 with parts that have run out are not caused. As described above, it is in the state of waiting for component replenishment.
[0071]
Then, in the case of such a component replenishment waiting state, the ejected tray plate 47 is once returned to the tray magazine 45, and the tray magazine 45 is moved to a replaceable position by the lifter 41 to be in a replaceable state. Thereby, the setup time at the time of transition to the next operation can be reduced. Also, when component mounting is terminated, the tray magazine 45 is moved to a replaceable position by the lifter 41 so that the tray magazine 45 can be replaced, so that the setup time at the time of shifting to the next operation can be reduced. .
[0072]
As described above, according to the component supply device 13 of the present invention, the tray plate 47 that has run out of components is pulled out to the tray plate mounting portion 63 where the operator can replenish the components 19, and after the components 19 are replenished, Since the tray plate discharging section 61 for feeding the original place is provided, the operator can easily replace the tray pallet 49 of the tray plate 47, which has run out of parts, and replenish the parts 19 without error. . As a result, it is possible to reduce the burden on the worker involved in replenishment of components, shorten the operation time, and improve the efficiency of the mounting operation.
[0073]
Further, when the tray plate 47 that has run out of components is detected, it is controlled whether the tray plate 47 is pulled out to the tray plate mounting portion 63 or the component 19 stored in another tray plate 47 is supplied. The determination is made by the unit 111 (or the main control unit 10 may make the determination). Thus, for example, when components are supplied to the mounting apparatus main body by the component supply unit 32, the component supply cassette, or the component supply tape, which is another component supply unit, the component 19 is transferred to the tray plate 47 that has run out of components. A replenishment operation can be performed. Further, when it is necessary to continuously supply the parts 19 of the same type as the parts 19 of the tray plate 47 that has run out of parts, it is possible to supply the parts 19 of the same type from the other tray plates 47. Interruption of the mounting work can be eliminated, and mounting work efficiency can be greatly improved.
[0074]
Further, when the component 19 is replenished to the tray plate 47, the component replacement switch 105 is operated to return the replenished tray plate 47 to complete the replenishment of the component 19 and to perform component supply. When the tray plate 47 is not ready to be replenished with components, the tray switch 47 can be returned once and the other components 19 can be supplied by pressing the skip switch 109. Further, if it is desired to cancel the return of the tray plate 47 pulled out to the tray plate mounting portion 63 in the middle for some reason, by pressing the cancel switch 107, the return operation of the tray plate 47 is stopped, and Work can be performed.
[0075]
Further, a plurality of tray pallets 49 accommodating parts 19 of different types or the same type are detachably held on the tray plate 47. Therefore, during the supply of some parts 19 of the tray pallets 49, the tray plate 47 can be pulled out and the other tray pallets 49 can be replaced to replenish the parts 19. In other words, parts can be replenished while parts supply is continued, and the working efficiency can be further improved.
[0076]
In addition, since the display unit 103 for displaying the out-of-part information is provided in the tray plate discharge unit 61, the operator can easily check the display on the display unit 103 and prepare the parts 19 to be replenished. Work can be facilitated.
[0077]
In the component mounting apparatus 100 of the above embodiment, the case where the tray pallet 49 accommodating the components 19 of the same type is held on the tray plate 47 has been described, but the components 19 of two or more different types are accommodated. A plurality of tray pallets 49 may be held on the tray plate 47.
[0078]
In this case, the tray plate discharge unit 61 discharges the tray plates 47 holding the tray pallets 49 of two or more types to the tray plate mounting unit 63, and exchanges the tray pallets 49 of these different types at once. Can be.
Further, depending on the setting conditions, even if the tray plate 47 holds a tray pallet 49 on which a component that is not out of components is mounted, if one kind of component runs out of components, the tray plate 47 is placed in the tray plate mounting portion. The tray 63 is discharged, and only the tray pallet 49 that has run out of components can be replaced.
[0079]
Further, the order of discharging the tray plates 47 to be discharged to the tray plate placement unit 63 of the tray plate discharging unit 61 is not limited to the order of the parts being exhausted, but may be the order set in advance for each type of the parts 19. . Further, it is also possible to discharge only the tray plate holding the tray pallet 49 of the component 19 of a specific type.
[0080]
Accordingly, the tray plate discharge unit 61 pulls out the tray plate 47 to the tray plate discharge unit in either the order of the tray plate in which the component has run out or the order of the component type in which the component break has occurred. It is possible to flexibly cope with the type of the circuit board 15 which is the mounted body to be mounted.
[0081]
【The invention's effect】
As described above, according to the component supply device and the control method of the present invention, the tray plate that has run out of components is pulled out to the tray plate mounting portion where the operator can replenish components, and the component replenishment is performed. Since the operator sends the tray plate to the original place later, the operator can very easily replenish the tray plate, which has run out of parts, without mistake. This can reduce the burden on the worker involved in component replenishment, shorten the operation time, and improve the efficiency of the component supply operation.
Further, according to the component mounting apparatus of the present invention, the component mounting apparatus does not stop due to the component supplying operation of the component supplying apparatus, and it is possible to replenish components while continuing component mounting, thereby reducing mounting time and increasing efficiency. Is achieved.
