(3) installation exercise of cover strip CV

After completing fixed operation, need to carry out stripping off device 90 to install the operation of cover strip CV.In this installation exercise, pushing roller 95 is lifted, away from outlet roller 93, and the front end of cover strip CV is inserted in the gap forming between two rollers 93,95.Then, make to push roller 95 and turn back to original position, thus, as shown in figure 24, the front end of cover strip CV is clipped between two rollers 93,95.Complete thus installation exercise, become stripping off device 90 and can batch the state of cover strip CV.

And under this state, if cover strip CV is pulled to device front side (the arrow B direction shown in Figure 24), as described below, the automatic entry into service of stripping off device 90, removes the lax of cover strip CV.

(4) by the lax removal of the cover strip operation of stripping off device

Controller 300 cooperates with the control device 109 of surface mounting apparatus 10, and stripping off device 90 is controlled.After having started to control, carry out S10 as shown in figure 25, the processing of S20, become and monitor the whether state of a control in inverted status of the second motor.Particularly, first, in S10, the position signalling Sc exporting according to position-detection sensor 311 detects the position of the rotor magnetic pole of the second motor 91.

Then,, in S20, according to described position probing result, judge by controller 300 whether the second motor 91 reverses.Two processing of described S10, S20, until till detecting the reversion of the second motor 91, repeatedly carry out.

At this, controller 300 starts stripping off device 90 to control in its startup.Therefore,, in the fixed operation of the component supplying apparatus 50 of described (2) completes, just start described stripping off device 90 to control.

As mentioned above, before operating personnel complete installation exercise, controller 300 just starts the processing (in detecting the state of a control of reversion) of described S10, S20.

Therefore, after the cover strip CV of (3) installation exercise completes, if cover strip CV is pulled to device front side by operating personnel, the strength of its drawing direction is delivered to the second motor 91 via outlet roller 93 and gear 92, make the second motor 91 reverse (rotating to the direction contrary with direction of recession), now, this reversion of motor is detected by controller 300 at once.Then,, by detecting that the described reversion of motor the judgement at S20 are judged as "Yes" in processing, the control operation of controller 300 enters the processing of S30.

In S30, by controller 300, rotation command is input to the control device 301 for managing the control to motor, make the second motor 91 start to rotate to forward direction.So, be the opportunity that makes the second motor 91 start to carry out forward driving to the detection of motor reversion.

When the second motor 91 starts to drive while causing stripping off device 90 to start, outlet roller 93 and pushing roller 95 rotate, and cover strip CV is sent to device rear (being left side in Fig. 9) by the frictional force causing by its rotation.Thus, cover strip CV becomes its lax being removed and the state strained, and meanwhile, the second motor 91 is locked and in halted state.Under this state, in the second motor 91, also to proceed permanent torque (constant torque) and control, its result, to applying on cover strip CV and the tension force of the setpoint torque formed objects of the second motor 91.

Thus, complete the installation exercise of First component supplying apparatus 50.Thereafter, can be according to described operating sequence, residue component supplying apparatus 50 is installed.

Then, all component supplying apparatus 50 of changing object at reel are arranged on component supplying apparatus installation portion 60, and after lax being removed of the cover strip CV of each component supplying apparatus 50, in each component supplying apparatus 50, carry out first element to be sent to the operation of component feeding position 51, thereby become the state of the installation exercise that can start element.

In addition, in the time making first element be sent to component feeding position 51, start by stripping off device 90, cover strip CV peels off from carrier band CA, but due to providing all the time motor current on the second motor 91, thereby this second motor 91 also can continue to produce thereafter certain torque.

Therefore, in the time that cover strip CV generation is lax, the second motor 91 rotates automatically, and outlet roller 93 and pushing roller 95 are driven, and the cover strip CV being clipped between described two rollers 93,95 is sent to device rear.Therefore, arrive component feeding position 51 at first element, stripping off device 90 is in the time of halted state, and cover strip CV remains on the state (there is no lax tension) that pulls to device rear.

In addition install in order to start surface, for example, as long as (carry out predetermined operation,, press and in the figure being arranged on surface mounting apparatus 10, there is no the beginning switch of expression etc.), thus, in the following order, the printed base plate P flowing through on conveyer belt 20 is started to the surface installation of element.

If carry out described predetermined operation, the control device 109 of surface mounting apparatus 10 starts (with reference to Fig. 2) such as X-axis motor 44 and Y-axis motor 46 according to program, thereby head assembly 40 is moved towards the component feeding position 51 of each component supplying apparatus 50.After head assembly 40 arrives component feeding position 51, head 41 carries out lifting, thereby takes out (absorption) first element by head 41.

And, after head 41 has adsorbed element, checked the skew of element absorption position by camera 12.Afterwards, transfer adsorbed element by head assembly 40, and in this handover, proofread and correct the skew of the position of components that each head 41 adsorbs.Then,, after head 41 arrives on the component installation location of the regulation in substrate P, head 41 carries out lifting, and is accompanied by this lifting, and element is installed on printed base plate P.Thus, complete the installation of first element.

On the other hand, the control device 109 of surface mounting apparatus 10, when the processing of described first element is installed, makes component supplying apparatus 50 carry out action from second element to component feeding position 51 that send.,, after head 41 has taken out first element, control device 109 sends the instruction of the supply that starts second element to the controller 300 of component supplying apparatus 50., receive the controller 300 of each component supplying apparatus 50 of this instruction, the first motor 81 is sent to driving signal, carrying device 80 is started.Thus, start sending of component feeding band TP, second element conveyance is to component feeding position 51.

Now, although the second motor, in halted state, receives the motor current Im providing, produce the torque of regulation, therefore, on cover strip CV, continue to be applied with the tension force of drawing direction.Therefore,, if carrying device 80 starts to send component feeding band TP, cover strip CV peels off from carrier band CA thereupon.And lax if cover strip CV occurs, the second motor 91 automatically rotates to remove this and relaxes.

So, when component feeding band TP send beginning after, in course of conveying, cover strip CV is stripped from, and therefore, only has carrier band CA to be sent to device front.And the cover strip CV peeling off, by between outlet roller 93 and pushing roller 95, is sent to band containing case 200.

Then,, after the sendout of component feeding band TP reaches specific length, the first motor 81 and even carrying device 80 stop action, thereby complete the conveyance of second element towards component feeding position 51.Thus, become the state of the installation exercise that can start second element.

Afterwards, as first element, take out by head assembly 41 second element that is positioned at component feeding position 51, then, second element taking out is installed on printed base plate P.

And, in carrying out that described second element is installed to the processing in substrate P, in component supplying apparatus 50, carry out the 3rd element to be sent to the action of component feeding position 51.

3. effect

In the present embodiment, the condition that is reversed to of the second motor 91 to be detected, make the second motor 91 carry out forward driving.Adopt this structure, after changing reel, although operating personnel need to be undertaken cover strip CV to be installed to installation exercise on stripping off device 90 (by manual operation, cover strip CV is inserted to the operation between outlet roller 93 and pushing roller 95), but, need only drawing cover strip CV lightly, just can make the second motor 91 and even stripping off device 90 automatically start, thereby remove the lax of cover strip CV thereafter.Therefore, do not need the lax removal of carrying out specially under normal circumstances to start operation (for example, by pressing the beginning switch that there is no expression in figure, making the second motor 91 start the operation driving), thereby can save the corresponding time.

In addition, in the present embodiment, utilize and be just arranged on the signal that the Hall element in motor is exported originally, detect the rotation situation (detecting reversion) of the second motor 91.Adopt this structure, increase that can suppressing portion number of packages, can reduce the cost of device.

(the second execution mode)

Below, with reference to Figure 26, describe with regard to the second execution mode of the present invention.In the second execution mode, by monitoring the rotating speed of the second motor 91, the abnormal conditions such as the fracture of detection cover strip CV.

Particularly, in the present embodiment, the second motor 91 is carried out to permanent torque control, thereby when motor is in no load condition when there is fracture etc. due to cover strip CV, compared with common use state, the rotating speed of the second motor 91 rises.

Consider this point, in the present embodiment, the higher limit of the rotating speed of the second motor 91 of observing under common state is set as to limits value.And, process according to following control flow (having increased the processing of S50～S80 in the control flow of the first execution mode), detect the abnormal conditions such as fracture according to described limits value thus, when detecting that carrying out mistake (error) when abnormal processes.

First,, in S30, the second motor 91 starts forward and drives, and then, carries out the processing of S50, S60.In the processing of S50, S60, the position signalling Sc exporting according to position-detection sensor 311 detects the rotating speed of the second motor 91, and judges by controller 300 whether the rotating speed detecting exceedes described limits value.

If occur the abnormal conditions such as the fracture of cover strip CV, rotating speed can rise and exceed limits value.Its result is judged as "No", and carries out the processing corresponding with abnormality in processing afterwards in the time that the judgement of carrying out S60 is processed.

First, in S70, the processing that the second motor 91 is stopped by controller 300, then, in S80, notify the mistake processing of abnormal conditions, for example, being made to be arranged on by the control device 109 of controller 300 and surface mounting apparatus 10 does not have the shinny processing such as the emergency warning lamp of expression in the figure on surface mounting apparatus 10.

Adopt described structure, in the situation that occurring that cover strip CV fracture etc. is abnormal, can find early this situation, thereby can improve the reliability of system.In addition, adopt the structure of present embodiment, special-purpose member need not be set separately, also can detect abnormal conditions, thereby, and by being set, special equipment detects compared with abnormal structure, more favourable on cost.

(the 3rd execution mode)

Below, with reference to Figure 27, describe with regard to the 3rd execution mode of the present invention.

In the first described execution mode, by the reversion of the second motor 91, detect the cover strip CV installation exercise to stripping off device 90, and, described in detecting, be reversed to condition, the second motor 91 is driven.And in the 3rd execution mode, by the displacement action of pushing roller 95, detected the cover strip CV installation exercise to carrying device 80.

Particularly, in the present embodiment, as shown in figure 27, be provided with limit switch 320 in the top position of pushing roller 95.

When operating personnel lift pushing roller 95 for cover strip CV being installed on stripping off device 90, the top of the pushing roller 95 lifting contacts with limit switch 320.Thus, limit switch 320 is to controller 300 output detection signal Se., controller 300 is judged as the installation exercise that stripping off device 90 has been carried out to cover strip CV, and this controller 300 is to the second motor 91 output drive signals, and the second motor starts forward and drives.

Even if adopt described structure, also can obtain the effect identical with the first execution mode.; although operating personnel need to be undertaken cover strip CV to be installed to the installation exercise on stripping off device 90 by manual operation,, thereafter by the action of limit switch 320; can make the second motor 91 automatically start forward and drive, thereby remove the lax of cover strip CV.Therefore, can omit the specialized operations of carrying out in order to remove the lax of cover strip CV.

In addition, in the present embodiment, by the limit switch 320 lifting for detection of pushing roller 95 and the controller 300 that detects the installation exercise that carries out cover strip CV according to the detection signal Se from this limit switch 320, form " installation exercise testing agency " of the present invention.

(the 4th execution mode)

In the 4th execution mode, according to circumstances switch the setpoint torque of the second motor 91.The concrete setting of torque, as shown in figure 28, after the second motor 91 has just started forward, is set as maximum torque.Thereafter, torque switches to intermediate level in the rotation way of motor, and in the time stopping, switching to little torque.Wherein, the switching of this torque is to offer by changing from control device 301 (with reference to Figure 21) that the current instruction value S of comparison circuit 313 realizes.

So, by the setpoint torque of switching motor according to circumstances, can suppress the fracture of cover strip CV.Particularly, when motor starting, need larger torque, still, after motor starts to rotate, if the upper tension force being applied with to a certain degree of cover strip CV, so large torque while not needing as motor starting.

If the setpoint torque of the second motor 91 remains on as started torque so large when forward, especially at motor in the time stopping, on cover strip CV, applying excessive strength, there will be fracture.But, if adopt described structure, owing to switching to less torque after motor starting, thereby can avoid described fracture in advance.And, adopt described structure, can suppress the current sinking of motor, also have superiority in this regard.

In addition, the concrete switching time of torque, should determine according to the rotation situation of motor, wherein, can judge by the rotating speed of the motor that detects according to the position signalling Sc of position-detection sensor 311 the rotation situation of motor.
