It should be noted that the number of times set in the EP1 data corresponds to the one in which no component is detected among the suction abnormalities, and the number of times set in the EP2 data indicates the recognition abnormality,
This is for a component that is detected to be in a standing state.

The operation of the above configuration will be described below. Here, on the screen of the mounting mode data,
As shown in FIG. 5, it is assumed that the alternate function of the component supply unit (7) is set to be canceled, and to be stopped after a predetermined number of suction abnormalities have occurred consecutively. In the part library data screen, as shown in FIG.
The operation will be described below assuming that the predetermined number (2) is set for both the EP1 and EP2 data.

First, when the printed circuit board (5) is conveyed to the supply conveyor (25) and placed on the XY table (1), the component supply unit (6) is moved by driving the component supply unit servo motor (8). And the step number "1" of the NC data
The component supply unit (7) with the reel number "1" is on standby at the component suction position of the suction station (I). Due to the rotation of the rotary table (11), the nozzle (1) which moves to the component removal position of the suction station (I) next.
2) The nozzle selection station (VII) selects a nozzle type corresponding to the component (4) to be sucked by the suction head (13) being rotated by the rotation of the drive gear (18). The suction nozzle (12) is lowered by the lowering of the head (13), and the chip component (4) supplied by the unit (7) is taken out. The component presence / absence detecting device (15) of the suction station (I) includes a suction nozzle (1).
The presence or absence of the component (4) sucked in 2) is detected, but it is assumed that the component (4) is detected as being sucked.

It moves to the recognition station (II) by the rotation of 1). In the recognition station (II), the recognition of the displacement of the component (4) sucked by the nozzle (12) with respect to the suction nozzle (12) and the recognition of the suction state and the like are performed by the recognition device (1).
6).

Based on the recognition result of the recognition device (16), the CPU
If the suction nozzle (12) reaches the nozzle rotation correction station (III) due to the rotation of the rotary table (11) when it is determined that the suction is normal in (21), the recognition device (16) recognizes the suction nozzle based on the recognition result. The first nozzle rotating device (17) rotates the nozzle (12) so that the angle becomes the angle specified by the NC data, and corrects the angle of the chip component (4).

Next, a component standing detection station (IV)
Then, it is detected whether or not the component (4) is sucked while standing on the nozzle (12), but it is assumed that the component (4) is detected to be sucked in a normal posture. Next, at the mounting station (V), the designated position of the NC data is positioned by the rotation of the X-axis servomotor (2) and the Y-axis servomotor (3) by the lowering of the suction nozzle (12). ) Is mounted with the chip component (4).

Further, the above-mentioned component presence / absence detection device (15),
When the CPU (21) determines from the detection and recognition results by the recognition device (16) and the component standing detection device (19) that the suction is abnormal (for example, there is no component, recognition error, component standing), the nozzle (12) The mounting operation at the mounting station (V) is not performed, and when the component (4) such as a recognition error or a standing state is being sucked, the component (4) is discharged at the next discharging station (VI).

The operation in the case where it is determined that the adsorption is abnormal will be described below. If a suction abnormality (for example, no component) occurs, the absence of the component is determined until the number of repetitions (two times) of EP1 data set in the part library data shown in FIG. 6 stored in the RAM (22) is reached. The interrupt recovery operation of the failed component (4) is performed.
That is, since the number of repetitive operations set for the component (4) is two consecutive times, the component (4) is re-adsorbed. In this case, when the suction head unit (13), which is determined to be suction-abnormal by the component presence / absence detection device (15) of the suction station (II), moves to the next station by rotation of the rotary table (11), the nozzle selection station is stopped. The suction head section (13) moved to (VII) performs suction of the component (4) at the suction station (I).
That is, the CPU (21) responds to the component (4) to be sucked when the head (13) moved to the nozzle selection station (VII) moves to the suction station (I) according to the step order of the NC data. Nozzle (1
Instead of selecting 2), in order to re-perform the suction operation of the component (4) in the step with respect to the component (4) determined to be abnormal in suction, the head unit (13) is connected to the drive gear (18). To select a nozzle (12) corresponding to the component (4) in which the suction abnormality has occurred. Then, the component (4) is sucked by the nozzle (12) as described above, and the presence / absence of the component (4) is detected by the component presence / absence detecting device (15). You can continue. That is, the recognition is made by the recognition station (II) by the movement of the table (11), and if it is determined that the suction is normal as a result of the recognition, the displacement of the component (4) is corrected thereafter, and then the mounting station (V) Then, the component (4) is mounted on the substrate (5). At this time, if the next recognition station (II) or component standing detection station (IV) determines that the recognition is abnormal or the suction is abnormal,
Similarly, when the suction head unit (13) moves to the next station by rotating the rotary table (11) based on the EP2 data, the suction head unit (13) moved to the nozzle selection station (VII) is The part (4) is suctioned at the suction station (I).

Then, the nozzle (12) corresponding to the component (4) in which the suction abnormality has occurred is selected by the selection station (VII) for the remounting operation in the step in which the suction abnormality is determined. Rotary table (11)
The operation of selecting the nozzle (12) for the part (4) of the step which should have been originally selected and interrupted by the step which has just been abnormal is moved to the head part (13) which is moved by the rotation of Is performed. The subsequent selection operation is performed according to the original steps.

If it is determined that there is no component again as a result of this detection, the number of repetitive operations counted by a counter (not shown) is equal to the set number of times (in this case, two times).
Has been reached, the component supply table (6) is moved, and the component supply unit (7) that has been detected as having no component (for example, FIG.
Is stopped at a predetermined position where the indicating member (29) is erected, the device is abnormally stopped (see FIG. 8), and the operator is notified by a not-shown notifying means. Then, the worker who has been notified that the abnormality has occurred has no component, so the component supply unit (7) in which the component (4) is empty is replaced with the unit (4) containing the component (4). 7), press the reel ready key (34) of the operation unit (31), and press the start key (32) to start the apparatus again. In the present embodiment, the number of repetitive operations after occurrence of an abnormality is set for each component. However, the present invention is not limited to this. For example, program control may be performed so that when an abnormality occurs, a predetermined number of re-operations are performed uniformly. Further, the apparatus may be immediately stopped and notified without restarting.

Further, the rotary table (1) is provided by a plurality of stations such as a suction station (I), a recognition station (II), and a parts standing detection station (IV).
1) Operation when suction abnormality (combination of no component, recognition error, component standing) occurs at one stop of intermittent rotation, abnormal stop, and continuous replacement of each supply unit (7) explain. In this case, for example, if the suction abnormality occurs at the suction station (I) and the recognition station (II) at the same time and the units (7) from which those parts (4) are taken out are the same or a plurality (two), the suction station (I) And parts standing detection station (I
If the unit (7) from which the parts (4) are taken out is the same or a plurality (two) at the same time, a suction error occurs at the recognition station (II) and the component standing detection station (IV) at the same time. If the units (7) from which these parts (4) are taken out are the same or a plurality (two), the suction station (I), the recognition station (II), and the part standing detection station (I)
In the case of V), a suction abnormality occurs at the same time, and the unit (7) from which those parts (4) are taken out may be the same or a plurality (two or three). here,
A description will be given of the case where the suction abnormality occurs simultaneously in the suction station (I) and the recognition station (II) and the number of units (7) from which those parts (4) are taken out is the same or plural (two).

First, the CPU (21) performs detection by the detection device (15) and the recognition device (16) at those stations.
As a result of the recognition, if the suction abnormality occurs in the number of repetitions set in the EP1 and EP2 data described above, the steps determined to be the suction abnormality are sequentially stored in the RAM (22), and the components of the two steps determined to be abnormal ( If 4) is taken out of the same unit (7), the supply table (6) is moved so that the supply unit (7) is located at the position indicated by the indicating member (29). Let it stop.

Then, based on the contents displayed on the display device, the operator sets the supply unit (7) designated by the designation member (29) in the component supply unit (7) of reel number 1, for example, with no component. If the recognition is abnormal,
For example, the worker takes out the component by the nozzle (12) because the suction operation is unstable (sometimes the suction cannot be performed, and sometimes the suction exceeds the correction limit in the nozzle rotation correction station (III) in the subsequent process). It is checked whether there is a position setting error, whether the unit (7) is installed on the supply stand (6), and the like, and the cause of the abnormality is eliminated.

Next, when the part (4) of the step determined to be abnormal is taken out from the separate unit (7), the CPU (21) determines that the suction is abnormal as described above. The steps are sequentially stored in the RAM (22), and the first step (absorption station (I) and recognition station (II)) in which it is determined that an abnormality has occurred
The step determined to be abnormal in either of the steps may be set first. Here, a description will be given below assuming that the step determined to be abnormal in the suction station (I) has been set first. The supply table (6) is moved and stopped so that the supply unit (7) corresponding to ()) is located at the position indicated by the indicating member (29).

Then, based on the contents displayed on the display device, the operator can set the supply unit (7) designated by the designation member (29) without any components in the component supply unit (7) of reel number 1, for example. If there is, the component supply unit (7) of the empty reel number 1 is replaced with the component supply unit (7) containing the component (4).
Next, when the operator presses the start key (32), the CPU (21) causes the CPU (21) to determine the unit (7) corresponding to the next step in which the suction is determined to be abnormal (the step in which the recognition station (II) determines that there is an abnormality). ) Is the indicating member (29)
The supply table (6) is moved so as to be located at the position indicated by. The operator inspects and eliminates the cause of the recognition error (for example, a wrong setting of the unit (7) to the supply stand (6) where a different part (4) is set).

If the supply table (6) is not moved even if the start key (32) is pressed, the cause of the suction abnormality in all the steps determined to be the suction abnormality has been eliminated.
The operator operates the reel ready key (34) of the operation unit (31).
Press the start key (32) to restart the device. Hereinafter, the same problem is dealt with even when the suction abnormality occurs simultaneously in other stations.

Next, a case will be described in which it is set in the mounting mode data to continue the operation after the occurrence of the suction abnormality. As described above, the mounting operation is performed, and if it is determined that suction is abnormal as a result of detection or recognition, the operation is repeated until the number of times set in the repetitive operation number data corresponding to the component (4) is reached. You.

If it is determined that the suction is abnormal even after the set number of times is reached, the suction (mounting) operation in the mounting step for handling the component (4) is not performed without stopping the apparatus. Of step (attachment) to the part (4)
Perform the operation. That is, if the component (4) of the component supply unit (7) repeats the suction abnormality in a certain mounting step, and it is determined that the suction is abnormal even when the set number of times has been reached, the CPU (21) executes that step in the RAM ( 22), the steps are sequentially set as shown in FIG. 9, and the steps for handling the part (4) are picked up from the NC data and these steps are also stored. When the mounting operation is performed in the order of the mounting steps, the step of handling the component (4) is skipped without performing the mounting operation, and the mounting operation of the component (4) in the step of processing another component (4) is performed. At this time, the fact (hereinafter, referred to as “recovery later”) is displayed on a display device (not shown) and is notified by the notification means. The display content is RECAL shown in FIG.
L MISCHUCK ERROR MESSAGE
For example, as shown in the screen of "absorption abnormality message", for example, the cause of the abnormality of the adsorption, the mounting step number in which the abnormality occurred, the reel number of the component supply unit (7), and E
These steps are displayed in P data or the like to indicate that these steps have been postponed for the recovery operation.

As described above, when all the suction operations of the component (4) other than the component (4) targeted for the postponed recovery are completed (final step), the CPU (21) performs the postponed recovery shown in FIG. The supply unit (7) set at the first of the targeted steps is the indicator member (2).
Supply stand (6) to be located at the position indicated in 9)
Move and stop. Then, based on the contents displayed on the display device, if there is no component in the component supply unit (7) of the reel number 1, for example, the worker supplies the empty component number of the reel number 1. Unit (7)
And the part supply unit (7) containing the part (4). Next, when the operator presses the start key (32), the CPU (21) causes the CPU (21) to use the instruction member (29) if there is another unit (7) that has been postponed and recovered. The supply table (6) is moved so as to be located at the designated exchange position. The operator replaces the unit (7). Similarly, other causes of the suction abnormality (for example, component standing, recognition abnormality, etc.) are dealt with as described above. Then, if the supply table (6) is not moved even when the start key (32) is pressed, the cause of the suction abnormality in all the steps that have been treated as the recovery recovery is eliminated, and the operator operates the operation unit (31). Is pressed, and the start key (32) is pressed to start the apparatus. Then, after the component (4) already sucked by the suction nozzle (12), the component (4) of each step which is postponed is suctioned, and the mounting operation is sequentially performed. At this time, the mounting operation is performed sequentially from the latest step of the steps stored in the RAM (22) in the order of occurrence of the abnormality. The mounting operation may be performed in the order (oldest order) stored in the RAM (22). If a suction abnormality occurs during the mounting operation in the later turning step, interrupt recovery is performed. Further, the RAM (2) is
2) The optimum NC data of only the step that has been postponed is determined based on the current position of the parts supply table (6) that is stopped, the position of the XY table (1), etc. The rebuilding may be performed to perform the mounting operation. When the mounting operation of the component (4) in the final mounting step is completed, the apparatus may be stopped, and after the restart, only the component (4) in the postponed step may be sucked and sequentially mounted. Further, the unit (7) of the component (4) handled in the postponed step is moved to the suction station (I).
, And is mounted on the supply stand (6), so that time loss is small.

Further, in this embodiment, when there are a plurality of supply units (7) determined to be the suction abnormality, there is a unit (7) for which the cause of the abnormality due to the inadvertent mistake of the operator has not been eliminated. By pressing the start key (32) in order to prevent the mounting operation from being restarted, if there is a unit (7) for which the cause of the abnormality has not been eliminated, the corresponding unit (7) is Although the supply table (6) is moved so as to be located at the position indicated by the indicating member (29), an operation key dedicated to confirmation may be provided.

Further, when the number of parts (4) is originally smaller than that of the other units (7) or when the unit (7) of frequently used parts (4) is used, a spare unit (7) is used.
