However, in the tray-type component supply device, since a plurality of trays are placed side by side on the table in the X-axis direction and the Y-axis direction, taking out the electronic circuit components from the tray becomes troublesome. When taking out electronic circuit components from each of the plurality of trays placed on the table, each position of the plurality of electronic circuit components arranged in the tray is acquired based on the reference position set for each tray, The component suction head is moved to suck the electronic circuit component. If a plurality of trays are provided side by side in the X-axis direction and the Y-axis direction, the movable range of the component suction head for taking out the electronic circuit component is set to X. Both the axial direction and the Y-axis direction must be widened, and the apparatus for moving the component suction head becomes large. Also, there will be trays with different reference positions in both directions, and when the tray for supplying electronic circuit components is changed,
It may be necessary to reset the reference position in the axial direction and the Y-axis direction, which complicates the control.

The plurality of feeders may be arranged in a state where the respective component supply units are arranged along a straight line, may be arranged in a state where the respective component supply units of the plurality of feeders are positioned on a straight line, or may be arranged in a state deviated from the straight line. In the latter case, for example, a plurality of feeders are arranged such that the respective component supply units are arranged in a staggered manner, and the respective component supply units of adjacent feeders are positioned on opposite sides with respect to a straight line.
The first support surface may be a horizontal surface, a vertical surface, an inclined surface, or the like. In the case of the horizontal plane, the feeder is supported from below by the first support surface, and in the case of the vertical plane, the feeder is supported by the first support surface at one end in a direction perpendicular to the arrangement direction.

Further, if a plurality of trays are stacked and supported by the support plate, a large number of trays can be placed on a limited support surface of the support plate. The mounting device receives electronic circuit components from the top of the stacked trays, but the height of the top tray changes each time the tray is emptied and removed. If the thickness (dimension in the height direction) of the tray is known in advance and the number of stacked trays is known, the height of the uppermost tray can be obtained from them, but an error occurs. Further, the thickness of the tray and the number of stacked sheets are not always known. On the other hand, if the height of the uppermost tray is detected by the tray height detecting device, an accurate height can be obtained, and the mounting device can appropriately hold the electronic circuit component. In addition, if the tray height detection device is configured as described above, the height position of the detection device main body and the vertical dimension of the height detection head (for example, detection in a state where the detector is retracted by a set amount from the protruding position). The height of the tray can be acquired based on the dimension from the rear end of the apparatus main body to the front end of the detector.
In addition, in the component mounting system according to the second aspect of the invention, particularly when the electronic circuit components are supplied by the feeder-type component supply device, the number of feeders is large, and the feeder supportable region by the first support surface is often wide.

On the other hand, in the tray-type component supply device of this section, a plurality of trays are supported by the support plate, so that a plurality of types or a large number of electronic circuit components can be supplied. The movable member is positioned at the supply position when the electronic circuit component is supplied, and is positioned at the retracted position when the operator is working. In order to supply electronic circuit components, the supply position is within the operating area of the component supply target device, but the retracted position can be set outside the operating area, and the electronic circuit parts can be replenished by refilling and replacing trays. Work such as setup change can be easily and safely performed without being hindered by the component supply target device.

It is the same as the width of the largest area. The feeder 120 is also positioned in the front-rear direction (direction parallel to the longitudinal direction of the feeder 120) and the left-right direction by a positioning device (not shown), and is detachably fixed to the feeder support table 122 by a fixing device (not shown). . In the feeder-type component supply device 12, a large number of feeders 120 are attached to the feeder support table 122 in a state where each component supply unit is positioned on a straight line parallel to the X-axis direction.

  Therefore, the plurality of trays 130 and the tray container 250 of the tray-type component supply device 10 are supported by the support surface 220 in a direction parallel to the direction in which the feeders 120 are aligned. The width of the support surface 220 of the tray-type component supply device 10 and the dimension in the direction parallel to the X-axis direction in this component mounting system are parallel to the width of the support surface 562 of the feeder-type component supply device 12, ie, the X-axis direction. In this case, the size in the direction parallel to the arrangement direction of the plurality of feeders 120 is almost equal, the tray supportable area is wide, and the number of trays 130 supported in the width direction can be increased.

  When the feeder-type component supply device 12 is connected to the component mounting machine 14, the carriage 550 is moved to move the feeder-type component supply device 12 to the component mounting machine 14, and its front portion (feeder support table 122 side). Is moved into the component mounting machine 14, and the lifting cylinder 184 is operated in a state where the pair of positioning holes 558 face the positioning pins 182. The feeder support table 122 is moved based on the operation. Pushed up. Accordingly, the pair of positioning holes 558 are respectively fitted to the positioning pins 182, and the carriage 550 is positioned and connected to the component mounting machine 14 in the horizontal direction. The positioning hole 558, the positioning pin 182 and the lifting cylinder 184 constitute a connecting device. By positioning the carriage 550, the feeder support table 122 is positioned with respect to the component mounting machine 14.

Thus, both the tray-type component supply device 10 and the feeder-type component supply device 12 are moved by the movement of the carriages 132 and 550, and the carriages 132 and 550 are similarly connected to the component mounting machine 14 by the positioning pins 182. While attached to the component mounting machine 14, the width of the support surface 220 of the tray-type component supply device 10 and the width of the support surface 562 of the feeder-type component supply device 12 are substantially equal to each other. The feeder-type component supply device 12 can be exchanged for each of the support plate 210 and the feeder support table 122 in units of carts. Further, the tray-type component supply device 10 or the feeder-type component supply device 12 can be provided on either side in the Y-axis direction of the substrate transfer device 24 of the component mounting machine 14, and feeders are provided on both sides of the substrate transfer device 24. The mold part supply device 12 can be provided, the tray type component supply apparatus 10 can be provided, the tray type component supply apparatus 10 can be provided on one side, and the feeder type component supply apparatus 10 can be provided on the other side. The tray-type component supply device 10 and the feeder-type component supply device 12 can be selectively provided only on one side of the substrate transport device 24.

The position in the direction parallel to the arrangement direction of the plurality of feeders 120 is also the same.

  This component mounting system is controlled by a control device 500 shown in FIG. The control device 500 is mainly composed of a mounting control computer 510 including a CPU 502, a ROM 504, a RAM 506 and a bus 508 connecting them, and the input / output unit 512 includes the input device 290, the open / close sensor 330, and the pressure detection device. 460, an image processing computer 514 that processes image data obtained by the mark camera 104 or the like is connected. In addition, various actuators such as an X-axis moving motor 44 are connected to the input / output unit 512 via the drive circuit 520, and the display screen 294 of the display device 292 is controlled via the control circuit 522. The ROM 504 stores various programs and data such as a slider movement control program shown in the flowchart of FIG.

  When the tray-type component supply device 10 is connected to the mounting device 28 by the connecting device, the signal line and the like are connected and controlled by the control device 500, and the output signal of the open / close sensor 330 is input to the computer 510. . Management of the remaining number of electronic circuit components in the tray-type component supply device 10 is performed by the computer 510. In the feeder-type component supply device 12, for example, a computer (not shown) is provided for each of the plurality of feeders 120 to control the tape feeder and the like. In a state where the feeder-type component supply device 12 is provided in the component mounting machine 14, the computer of the feeder 120 is connected to the mounting control computer 510 and can communicate. The parts feeding of the feeder 120 may be controlled by the mounting control computer 510.

Next, the operation will be described.
When the electronic circuit component is mounted on the circuit board 22, the component suction head 62 is held by the head holding device 60 and moved by the head moving device 32, and the electronic circuit is supplied from the tray type component supply device 10 or the feeder type component supply device 12. The components are taken out, transferred to the circuit board 22 and mounted. The electronic circuit component sucked by the suction nozzle 82 during the movement is imaged by the component imaging device 80, and the holding position error of the electronic circuit component by the suction nozzle 82 is calculated. This holding position error is corrected together with the position error of the component mounting position obtained based on the imaging of the reference mark 100 on the circuit board 22, and the electronic circuit component is in a normal posture at the normal component mounting position of the circuit board 22. Installed. The tray-type component supply device 10 and the feeder-type component supply device 12 have the same component supply area in the direction parallel to the arrangement direction of the plurality of feeders 120, and the component suction head 62 is moved to supply the tray-type component supply. When the electronic circuit component is taken out from the device 10 or the feeder-type component supply device 12, the same region is moved in the X-axis direction, and the movement of the component suction head 62 can be used without waste.

As described above, the tray-type component supply device 10 is connected to the component mounting machine 14 in the carriage 132, and the trays 130 of the types and numbers corresponding to the types and numbers of the circuit boards 22 on which the electronic circuit components are mounted are the support plates. The slider 162 is moved to the supply position and supported by the tray container 250 directly or in the tray container 250, and the tray 130 supported by the support plate 210 is moved in the component mounting machine 14 as shown in FIG. 5. Therefore, the component suction head 62 is positioned within the moving region. Prior to the start of mounting electronic circuit components on the series of circuit boards 22, the positions of the first and second reference marks 280 and 282 of the L-shaped ruler 270 are detected, and a plurality of trays 130 are provided. If they are stacked, the height of the uppermost tray 130 is detected.

  When the positions of the first and second reference marks 280 and 282 are detected, the mark camera 104 is moved to the L-shaped ruler 270 and images the first reference mark 280. The attachment position of the L-shaped ruler 270 in the X-axis direction is input and instructed by the operator, and the position in the Y-axis direction is obtained by the positioning by the positioning surface 224 and the connection position of the carriage 132 to the component mounting machine 14. The mark camera 104 is moved based on the L-shaped ruler position data, and the first reference mark 280 and the second reference mark 282 are imaged. The position of the second reference mark 282 is obtained from the design dimensions of the L-shaped ruler 270. When there are a plurality of L-shaped rulers 270, the first and second reference marks 280 and 282 are imaged for each L-shaped ruler 270. Then, the image data is processed, and the positions of the first and second reference marks 280 and 282 are obtained. Based on these positions, the position error of each of the plurality of receiving recesses 246 of the tray 130 is calculated, and when the suction nozzle 82 sucks the electronic circuit component, the movement position of the component suction head 62 is corrected based on the position error, The position error is cancelled, and the electronic circuit component can be accurately picked up by the suction nozzle 82. When the tray 130 is stored in the tray container 250 like the small tray 130, the tray 130 is stored in the storage unit 252 and positioned with respect to the tray container 250. The positions of the plurality of trays 130 and the positions of the receiving recesses 246 of the trays 130 are known, and the position error of the receiving recesses 246 is acquired based on the positions of the first and second reference marks 280 and 282. The movement position of the component suction head 62 during component suction is corrected so that the position error is canceled out.

  When detecting the height of the tray 130, the head holding device 60 holds the height detection head 422. If the head currently held by the head holding device 60 is not the height detection head 422, it is moved to the head storage device 86, and the held head is stored in the head storage device 86, and the height detection head 422 is moved. Hold. Then, the height detection head 422 is moved to the position of the tray 130 for detecting the height, here, the uppermost tray 130 of the plurality of stacked trays 130, and a predetermined position of the tray 130, for example, As shown by a two-dot chain line in FIG. 6, the pad 440 is moved down onto the height detection position set in the vicinity of the first reference mark 280 of the L-shaped ruler 270 and then lowered. Is brought into contact with the upper surface of the tray 130. The type of tray 130 supported by the support plate 210, the support position, the number of sheets to be stacked, and the like are obtained from the tray arrangement data or tray support data created to support the tray 130 on the support plate 210, and the height according to the data. The detection head 422 is moved to the height detection position. The pad 440 can detect the height of the tray 130 regardless of the position on the upper surface of the tray 130, but it is desirable that the pad 440 be in contact with a portion having high strength. The vicinity of the first reference mark 280 of the L-shaped ruler 270 of the tray 130 is a corner of the tray 130, and when the pad 440 is brought into contact, the proportion of the receiving recess 246 in the contact surface is small. The strength is ensured at the time of contact.

At the start of the descent, the detector 432 in the height detection head 422 is in the protruding position by the bias of the spring 434 as shown in FIG. 10, and further protrusion is prevented by a stopper (not shown). Then, the height detection head 422 is lowered by the head lifting device 88 while negative pressure is supplied to the internal space 452. The height detection head 422 is further lowered from the state where the pad 440 is in contact with the upper surface of the tray 130. This lowering is allowed by compressing the spring 434, the head main body 424 is lowered with respect to the detector 432, and the detector 432 is retracted. Thereby, at least a part of the opening 450 enters the fitting hole 430 and is blocked by the head main body 424, and the flow rate of air flowing into the internal space 452 from the outside is reduced. Negative pressure becomes stronger. The absolute value of the negative pressure detected by the pressure detection device 460 increases, and the absolute value is compared with a set value. If the absolute value exceeds the set value, the height detection head 422 reaches the height detection position of the tray 130. It is assumed that the height has been lowered, and the descent of the height detection head 422 is stopped.

  The lowered position of the height detection head 422 is obtained from the output value of the encoder of the head lifting / lowering motor 94, and the output value of the encoder at the moment when the absolute value of the negative pressure detected by the pressure detection device 460 reaches the set value. Based on the distance from the upper surface (held surface) of the held portion 426 to the lower surface of the pad 440 in that state, the height of the upper surface of the uppermost tray 130 is obtained. The “distance from the upper surface of the held portion 426 to the lower surface of the pad 440” is acquired in advance in terms of design in relation to the set pressure for determining the increase in the negative pressure in the internal space 452.

  In the present embodiment, the detection of the height of the tray 130 is performed only for a plurality of stacked trays 130. The detected height of the tray 130 is used when the component suction head 62 takes out the electronic circuit component from the tray 130, and the component suction is performed based on the height of the tray 130 and the height (thickness) of the electronic circuit component. The descending distance of the head 62 is controlled, and the electronic circuit components can be sucked to the suction nozzle 82 without fear of damage to both. The height of the uppermost tray 130 detected for each of the trays 130 horizontally arranged on the support plate 210 is stored in the RAM 506 in association with the position of the L-shaped ruler 270 for positioning the tray 130, and the electronic circuit component. Used when adsorbing. Since the trays 130 accommodated in the tray container 250 are not stacked, the height of the small trays 130 is acquired by design and the height is not detected, but may be detected.

  After the height detection, the height detection head 422 is raised and separated from the tray 130 and returned to the head storage device 86, and the component suction head 62 is held by the head holding device 60 to supply electrons to the circuit board 22. A circuit component is mounted. Since the pad 440 of the height detection head 422 is made of tetrafluoroethylene and has low adhesiveness, the electronic circuit component housed in the housing recess 246 sticks to the pad 440 when being brought into contact with the upper surface of the tray 130. Thus, it is possible to avoid being pulled out of the housing recess 246. Further, the set load of the spring 434 that biases the detector 432 is made as small as possible, so that the load applied to the tray 130 when the detector 432 is retracted with respect to the head main body 424 can be reduced. Further, since the tray 130 is made of, for example, a synthetic resin and has low rigidity, the height detection head 422 has the detector 432 as light as possible and is provided with a pad 440 so that the tray 130 is not damaged. It is made to contact.

  While the electronic circuit components are being supplied by the tray-type component supply device 10, if the uppermost uppermost tray 130 of the plurality of stacked trays 130 becomes empty, the empty tray 130 is collected. The tray 130 disposed in the box 352 and stacked below becomes the uppermost tray 130 to supply electronic circuit components. The mounting control computer 510 counts and manages the number of electronic circuit components accommodated, the number of removal, the remaining number, etc. in each of the plurality of trays 130 positioned and supported on the support plate 210 when the electronic circuit components are mounted. If the remaining number becomes 0, the tray 130 is discarded. The disposal of the empty tray 130 is performed simultaneously with the generation of the empty tray 130 when, for example, the supply of the electronic circuit components supplied by the empty tray 130 is necessary immediately. When, for example, the supply of the electronic circuit components by the tray-type component supply device 10 is completed, or when the mounting of the electronic circuit components on one circuit board 22 is completed and the circuit board 22 is carried in and out. To be done.

When discarding the empty tray 130, the head holding device 60 returns the component suction head 62 to the head storage device 86 and holds the tray suction head 410. Then, after being moved onto the empty tray 130, it is lowered, and the empty tray 130 which is the uppermost tray 130 is adsorbed by negative pressure. At this time, the support plate 210 is kept in the supply position, the tray suction head 410 is moved upward and lowered at the central portion of the tray 130, and the seal portion 419 is moved to the central portion of the tray 130. It is brought into contact with the surface or top surface. Since the seal portion 419 has a rectangular shape and extends radially from the head main body 424, the seal portion 419 is in wide and elastic contact with the upper surface of the empty tray 130, and an accommodation recess 246 on the upper surface of the empty tray 130 is provided. The tray adsorbing head 410 is brought into contact with the tray 130 in a state where the contact portion between the portion not formed and the seal portion 419 draws a closed curve and leakage of negative pressure from the recess of the housing recess 246 is prevented. The detected height of the tray 130 is also used for the lowering of the tray suction head 410, and the lowering position of the tray suction head 410 is controlled to contact the empty tray 130 with less impact, so that the empty tray 130 can be quickly and reliably removed. To be held. The extra lowering distance of the tray suction head 410 is absorbed by the compression of the seal portion 419, and the seal portion 419 is brought into close contact with the upper surface of the tray 130. A cushion mechanism may be provided in the tray suction head 410 so that the tray suction head 410 can be allowed to descend after the seal portion 419 is brought into contact with the tray 130. It is not essential to use the height of the tray 130 detected when the tray suction head 410 is lowered.

  Then, a positive pressure is supplied to the head body 412 and is changed to a negative pressure, and the tray suction head 410 sucks the tray 130. In this state, when the tray suction head 410 is raised and the tray 130 is lifted, the slider 162 is moved from the supply position to the retracted position side. At this time, the slider 162 is not moved to the retracted position, and the support plate 210 is at a position sufficient to open the upper opening 354 of the tray chute 350 and moves from the retracted position to the open position on the supply position side. Be made. Therefore, the moving distance of the slider 162 is short, and the upper opening 354 can be quickly opened. As shown in FIG. 3, in the state where the slider 162 is located at the supply position, the large tray 130 positioned and supported by the support plate 210 is located in the upper opening 354 in the front-rear direction. If the entire empty tray 130 is positioned in the upper opening 354 in the horizontal direction, the tray suction head 410 is not moved in the horizontal direction with the empty tray 130 lifted, and the slider 162 moves to the open position. Wait for. If at least a part of the empty tray 130 is located at a position away from the upper opening 354, the tray suction head 410 is moved in the horizontal direction in parallel with the movement of the slider 162 to the open position, and the entire empty tray 130 is moved. Is moved to a disposal position located in the upper opening 354. Then, after the slider 162 is moved to the open position and the upper opening 354 is opened, the supply of positive pressure to the tray suction head 410 is stopped, the negative pressure disappears, and the tray suction head 410 sucks the empty tray 130. Is released. Therefore, the empty tray 130 is dropped onto the tray chute 350, is guided by the guide surface 358, moves to the empty tray collection box 352, is discharged from the lower opening 356, and is accommodated in the empty tray collection box 352. Since the size in the width direction of the upper opening 354 and the lower opening 356 of the tray chute 350 is the size of a plurality of large trays 130, many of the plurality of empty trays 130 arranged in the width direction of the component supply device 10 are used. , The horizontal loading position on the tray chute 350 can be varied, and the empty tray 130 is accommodated in the tray collection box 352 without overlapping at a specific portion in the tray collection box 352.

  After the empty tray 130 is dropped onto the tray chute 350, the slider 162 is moved to the supply position so that the tray 130 supplies the electronic circuit components. Then, by removing the empty tray 130, the height of the uppermost tray 130 is detected by the tray height detection device 420. The tray suction head 410 is returned to the head storage device 86, and the height detection head 422 is held by the head holding device 60 and moved to the tray 130 to detect the height. The empty tray discarding device 400 is a tray removing device in that the top one of the stacked trays 130 is held and removed from above the second and subsequent trays 130.

When it is necessary to perform operations such as replenishment of electronic circuit components on the tray-type component supply device 10 during the mounting operation of the electronic circuit components on the circuit board 22, the operator uses the slider 1.
62 is moved to the retracted position, and the support plate 210 and the tray 130 are moved to the retracted position. In the tray-type component supply device 10, the movement of the slider 162 to the retracted position during the mounting operation is instructed by the operator rotating the cover 320 from the closed position to the open position by a predetermined amount and returning it again to the closed position. The The movement control of the slider 162 based on the opening / closing operation of the cover 320 by the operator will be described based on the slider movement control program shown in FIG.

  This program is executed after the start of mounting the electronic circuit components on the series of circuit boards 22. Then, in step 1 (hereinafter abbreviated as S1. The same applies to other steps), it is determined whether or not the cover 320 is closed (whether or not the cover 320 is in the closed position). This determination is made based on a signal from the open / close sensor 330, and it is determined whether or not an OFF signal is output. If the cover 320 is closed and an OFF signal is output, the determination result of S1 is YES, S2 is executed, and whether or not the cover 320 is opened (whether the cover 320 is not in the closed position). ) Is determined. This determination is made based on whether or not the signal of the open / close sensor 330 is an ON signal. If the cover 320 is closed, the determination result of S2 is NO and S2 is repeatedly executed. If the cover 320 is opened and an ON signal is output, the determination result of S2 is YES and S3 is executed. After the determination result of S2 is YES, it is determined whether or not the set time has elapsed. Done. The set time is such a length that it can be determined that the opening / closing of the cover 320 instructs the movement of the slider 162 to the retracted position, and is set to a short time, and is set by a timer provided in the mounting control computer 510. Measured.

  The determination result of S3 is NO until the set time elapses, and S4 is executed to determine whether or not the cover 320 is closed. If the cover 320 is not closed and remains open, the determination result in S4 is NO and S3 is executed. If the set time elapses without the cover 320 being closed, the determination result in S3 is YES, S1 is executed, and it is determined whether or not the cover 320 is closed. If the set time has elapsed without the cover 320 being closed, it is considered that the cover 320 has been opened for a purpose other than an instruction to move the slider 162, and the cover 320 is awaited to be closed.

  If the cover 320 is closed before the set time elapses, the determination result in S4 is YES, S5 is executed, and it is determined whether or not the slider 162 can be moved to the retracted position. In the state where the tray-type component supply device 10 supplies electronic circuit components, the tray 130 cannot be retracted, and therefore the determination of S5 is performed. The slider 162 can be moved to the retracted position when the tray-type component supply device 10 is not supplying the electronic circuit component. For example, the electronic circuit component on one circuit board 22 can be moved. In this state, the electronic circuit component is taken out from the feeder-type component supply device 12 or the circuit board 22 is being carried in and out. Since the determination of S5 is made based on the progress of the mounting operation of the electronic circuit components ascertained by the mounting control computer 510, the electronic circuit components are taken out from the tray-type component supply device 10 and attached to the circuit board 22. If there is, the slider 162 cannot be retracted, the determination result in S5 is NO, S6 is executed, and that fact is displayed on the display screen 294 and notified to the operator.

If it is possible to move the slider 162 to the retracted position, the determination result in S5 is YES, S7 is executed, and the slider 162 is started to move to the retracted position by the slider driving device 166. The slider 162 is started to move in a state where the tray-type component supply device 10 is connected to the component mounting machine 14, that is, in a state where the elevating member 138 is positioned in the ascending position or the connecting position. It is moved out of 186, that is, out of the component mounting machine 14 and out of the moving region of the component suction head 62. Next, S8 is executed, and it is determined whether or not the slider 162 has reached the retracted position. This determination is made based on the output value of the encoder of the belt circling motor 200, for example.
This is done by acquiring 62 positions. This encoder is an incremental encoder in this apparatus. Each moving end of the retracted position and the supply position of the slider 162 is defined by a stopper (not shown), and movement to each moving end is detected by a sensor. In addition, the output value of the encoder at the moving end is acquired, and thereafter the movement of the slider 162 to the retracted position and the supply position is detected based on the output value of the encoder.

  The determination result of S8 is NO until the slider 162 reaches the retracted position, S9 is executed, and it is determined whether or not the cover 320 has been opened. The movement of the slider 162 is started when the cover 320 is closed. During the movement of the slider 162, the cover 320 should be closed, but it may be opened for some reason during the movement. If the cover 320 is not opened, the determination result in S9 is NO and S8 is executed. If the slider 162 reaches the retracted position without opening the cover 320, the determination result in S8 is YES, S12 is executed, and the slider 162 is gently stopped.

  If the cover 320 is opened during the movement of the slider 162, the determination result in S9 is YES, S10 is executed, and the slider 162 is gently stopped. The belt rotating motor 200 is controlled, and the slider 162 is slowly stopped while being smoothly decelerated. The slider 162 is smoothly decelerated when stopped at the retracted position and the supply position, but is decelerated in the same pattern as that case. The open / close sensor 330 is configured by a photoelectric sensor. When the cover 320 is rotated from the closed position toward the open position, the opening / closing sensor 330 is rotated more than the set amount of the cover 320 until it is detected that the cover 320 is opened. When the cover 320 is rotated from the closed position to the open position by an amount larger than the set amount, it is detected that the cover 320 is opened (not in the closed position), and the slider 162 is stopped. To be done. In this apparatus, as described above, if the cover 320 is closed before the set time elapses after it is detected that the cover 320 is not in the closed position, the first setting is made from the closed position toward the open position. It is assumed that the cover 320 is closed again after being rotated by an amount less than that amount, and the cover 320 needs to be rotated more than the set amount until it is detected that the cover 320 is not in the closed position. If it is detected that is not in the closed position, it is assumed that the cover 320 is opened more than the second set amount. The open / close detection device includes a timer. Based on the time measured by the timer, it is determined whether or not the rotation amount of the cover 320 is equal to or less than the first set amount, and the timer is used instead of the switch so that the switch One is sufficient, and the open / close detection device can be constructed at low cost.

  And S11 is performed and it is determined whether the cover 320 was closed. If the cover 320 is not closed, the determination result in S11 is NO and S10 is executed. As a result, if the cover 320 is closed while the control for gently stopping the slider 162 is being performed and the slider 162 is not yet stopped, the determination result in S11 is YES and S7 is executed. Then, the slider 162 is restarted to move to the retracted position. If the cover 320 is not closed until the slider 162 is stopped, the determination result in S11 is not YES, and after the slider 162 stops, S10 and S11 are repeatedly executed, and it is awaited that the cover 320 is closed. In this case, the slider 162 has already been stopped, and substantially nothing is performed in S10. If the cover 320 is closed, the determination result in S11 is YES, S7 is executed, and the slider 162 is again started to move to the retracted position. If the cover 320 is opened before the slider 162 reaches the retracted position, S10 and S11 are executed each time. If the slider 162 reaches the retracted position, the determination result in S8 is YES, S12 is executed, and the slider 162 is gently stopped.

After the slider 162 reaches the retracted position, S13 is executed to determine whether or not the cover 320 has been opened. The slider 162 is moved to the retracted position, for example, to replenish electronic circuit components. The cover 320 is usually opened. The determination result in S13 is YES and S14 is executed. It is determined whether 320 has been closed. The electronic circuit components can be replenished, for example, in units of trays. For example, if the tray 130 is completely removed, the tray 130 is newly placed on the support plate 210 or the tray 130 remains. In this case, the tray 130 is added or the electronic circuit components are accommodated in the empty accommodation recesses 246 of the tray 130. Further, if the tray 130 is empty in the tray container 250, the tray 130 is replaced with a tray 130 in which electronic circuit components are stored, or the tray 130 is replaced with the tray container 250 to replenish electronic circuit components. To do. The tray 130 may be exchanged together with the support plate 210. The support plate 210 is detachable from the slider 162. The support plate 210 supports the tray 130 in which the electronic circuit components are accommodated by removing the carriage 132 from the slider 162 while being connected to the component mounting machine 14. Is attached to the slider 162. As described above, since the support plate 210 has a honeycomb structure and is lightweight, an operator can easily perform the above-described attachment / detachment operation. In addition, since the rigidity is high, the bending of the support plate 210 during work is so small that it can be ignored, and the tray 130 positioned on the support plate 210 is not displaced. Further, the white board marker can indicate the approximate position of the L-shaped ruler 270 and the tray 130, and can display information such as the type of the electronic circuit component 248 accommodated in the tray 130.

  The slider 162 is moved to the retracted position in a state where the electronic circuit components are not supplied by the tray-type component supply device 10, so that the electronic circuit by the tray-type component supply device 10 is used for replenishment of the electronic circuit components. It is not necessary to interrupt the supply of the components and the mounting, and it is possible to perform the replenishment operation of the electronic circuit components without reducing the mounting efficiency. If the electronic circuit component is being mounted on the circuit board 22, the electronic circuit component is supplied to the circuit board 22 by the feeder-type component supply device 12 in parallel with the electronic circuit component supply operation for the tray-type component supply device 10. Thus, the tray type component supply apparatus 10 can be operated without stopping the mounting operation and reducing the mounting efficiency. If the work on the tray-type component supply device 10 cannot be completed before the electronic component is supplied by the feeder-type component supply device 12, the completion of the operation is awaited. Since the work can be performed while the electronic circuit component is supplied by the device 12, it is possible to suppress a reduction in the mounting efficiency.

  When the worker finishes the work and closes the cover 320, the determination result in S14 is YES, S15 is executed, and the slider 162 is started to move to the supply position. Then, S16 to S20 are executed in the same manner as S8 to S12, and if the cover 320 is opened during the movement of the slider 162 to the supply position, the slider 162 is smoothly decelerated and stopped gently. If the slider 162 reaches the supply position, the determination result in S16 is YES, S20 is executed, and the slider 162 is gently stopped. Whether or not the slider 162 has reached the supply position is determined based on the output value of the encoder of the belt circling motor 200 and the output value of the encoder at the moving end of the slider 162 acquired in advance. Then, S21 is executed, the first and second reference marks 280 and 282 are imaged and their positions are detected, and the height of the uppermost tray 130 is detected. When the supply of the electronic circuit components by the feeder-type component supply device 12 is completed, the electronic circuit components are mounted on the circuit board 22 by the supply of the tray-type component supply device 10, and the acquired reference marks 280 and 282 are obtained at that time. And the height of the top tray 130 are used.

When the type of the circuit board 22 to which the electronic circuit component is mounted changes and the setup change is performed, if the type of the electronic circuit component to be mounted changes, the slider 162 is moved to the retracted position, and the electronic circuit component is moved. Exchanged. The movement of the slider 162 may be instructed by opening / closing the cover 320 or may be performed based on an instruction input by the input device 290.
In this case, the input device 290 is also an operation device. The setup change in the tray type component supply apparatus 10 may be performed by exchanging the tray 130 or may be performed by exchanging the tray 130 together with the support plate 210. In the former case, the mounting position of the L-shaped ruler 270 can be changed if necessary. In the latter case, it can be considered that the tray-type component supply device 10 is replaced with another tray-type component supply device 10 having a common element other than the support plate 210 and the tray 130 together. In any case, after the setup change, after the cover 320 is closed, the slider 162 is moved to the supply position, the positions of the first and second reference marks 280 and 282 are detected, and the height of the uppermost tray 130 is detected. Detection is performed and used for the mounting operation.

  The carriage 132 is rarely released once it is connected to the mounting device 28, but when it is released, the elevating member 138 is lowered to disengage the positioning hole 180 from the positioning pin 182. Then, the carriage 132 is moved, and the tray-type component supply device 10 is moved from the component mounting machine 14. Thereby, for example, when changing the setup, the tray-type component supply device 10 is removed from the component mounting machine 14 together with the carriage 132, and for example, the support plate 220 is replaced with another tray-type component supply device 10 or feeder-type component supply device 12. Thus, the setup change can be performed. At this time, the tray-type component supply device 10 and the feeder-type component supply device 12 are exchanged together with the support plate 210 and the feeder support table 122 for each carriage.

  In the feeder-type component supply device 12, for example, when there is no electronic circuit component for at least one of the plurality of feeders 120 and it is necessary to replenish, for example, the replenishment can be performed in units of feeders. The feeders 12 that need to be replenished may be replaced individually, or the feeder-type component supply device 12 may be moved by the carriage 550 and replaced with the feeder support table 122. If the feeder support table 122 is replaced, when a plurality of feeders 120 that need to be replenished with electronic circuit components are generated, the feeders 120 can be replaced collectively to replenish electronic circuit components. The supply of the electronic circuit component is performed, for example, during the supply of the electronic circuit component by the tray-type component supply device 10, and is performed without interrupting the mounting of the electronic circuit component, and the reduction in the mounting efficiency can be suppressed. Further, when the type of the circuit board 22 on which the electronic circuit component is mounted is changed and the setup is changed, for example, the feeder-type component supply device 12 is detached from the component mounting machine 14 together with the carriage 550, for example, a feeder support table. Each 122 is replaced with another feeder-type component supply device 12 or tray-type component supply device 10. The setup change may be performed in units of feeders, and the setup change may be performed by attaching or detaching the feeder 120 to or from the feeder support table 122.

  As is apparent from the above description, in this embodiment, the part of the control device 500 that executes S1 to S4 and S7 constitutes a retreat start control unit, and the part that executes S13 to S15 serves as a forward start control unit. The portions that are configured and execute S9 and S10 constitute a movement stop control unit, and these constitute a slider drive device movement control device. In addition, the part of the control device 500 that executes S5 constitutes a retreatability determination unit. Furthermore, the remaining number of electronic circuit components in the tray 130 of the control device 500 is managed, and the portion that detects that the tray 130 is empty constitutes an empty tray detection unit, and the empty tray is discarded when an empty tray is generated. The part that controls the apparatus 400 and causes the empty tray 130 to be discarded in the tray collection box 352 constitutes an empty tray disposal control unit.

  Note that the opening / closing detection device that detects opening / closing of the cover that covers the support plate in the retracted position may include a plurality of, for example, two sensors. For example, the open / close detection device 600 shown in FIG. 14 includes two photoelectric sensors 602 and 604. The photoelectric sensors 602 and 604 include light emitting elements 606 and 608 and light receiving elements 610 and 612, respectively. For example, the photoelectric sensors 602 and 604 are transmissive, and are provided on the elevating member 614 at a distance in the vertical direction. The photoelectric sensors 602 and 604 may be of a reflective type.

  These photoelectric sensors 602 and 604 detect a dog 622 provided on the cover 620 and detect opening and closing of the cover 620. The photoelectric sensors 602 and 604 output different signals in a state where the light reception of the light receiving elements 610 and 612 is blocked by the dog 622 and a state where the light reception is not blocked, for example, output an OFF signal in a state where the light reception is blocked, When the light reception is not hindered and allowed, an ON signal is output. The dog 622 has a length that can simultaneously prevent the light receiving elements 610 and 612 of the photoelectric sensors 602 and 604 from projecting, and is provided so as to protrude from the cover 620 to the lifting member 614 side.

  Therefore, the dog 622 can prevent or allow light reception of the light receiving elements 610 and 612 of the photoelectric sensors 602 and 604 by shifting the time as the cover 620 is opened and closed, and the output signal of the photoelectric sensor 602 is turned on. If it is a signal, the cover 620 is in the open position, and if the output signal of the photoelectric sensor 604 is an OFF signal, the cover 620 is in the closed position, and the output signal of the photoelectric sensor 602 is an OFF signal. If the output signal is an ON signal, it is detected that the cover 620 is located at an intermediate position between the closed position and the open position. If the rotation amount from the closed position of the cover 620 when the output signal of the photoelectric sensor 602 becomes an ON signal is the first set amount, the cover 620 is rotated more than the first set amount from the closed position toward the open position. If it is made, it will detect that cover 620 is located in an open position. When the cover 620 is rotated from the closed position toward the open position, the cover 620 is positioned at the closed position until the output signal of the photoelectric sensor 604 becomes the ON signal, but the output signal of the photoelectric sensor 604 is ON. If it becomes a signal, it is detected that the cover 620 is located at the intermediate position. If the cover 620 rotates more than the set amount toward the open position, the output signal of the photoelectric sensor 602 remains the OFF signal, but the output signal of the photoelectric sensor 604 becomes the ON signal, and this set amount is set to the second value. If the set amount is set, the second set amount is smaller than the first set amount, and when the cover 620 is rotated more than the second set amount from the closed position toward the open position, the turn amount is equal to or less than the first set amount. During this time, the cover 620 is assumed to be positioned at the intermediate position. Although the cover 620 is larger than the second set amount, it is detected that the cover 620 has been turned toward the open position by an amount equal to or less than the first set amount.

The detection signals of the photoelectric sensors 602 and 604 are input to the mounting control computer, and the operation control of the slider driving device 166 based on the detection of opening / closing of the cover 620 by the sensors 602 and 604 is performed as follows. Since both the output signals of the photoelectric sensors 602 and 604 are in the OFF signal state, the output signal of the photoelectric sensor 604 becomes the ON signal, and the output signal of the photoelectric sensor 604 becomes the ON signal again without the output signal of the photoelectric sensor 602 becoming the ON signal. If it is detected that the cover 620 has been turned from the closed position to the intermediate position but has returned to the closed position without being turned to the open position, the slider driving device 166 is informed. The movement of the slider 162 from the supply position to the retracted position is started. If the output signals of the photoelectric sensors 602 and 604 both change from the ON signal to the OFF signal and it is detected that the cover 620 is rotated from the open position to the closed position, the slider drive device 166 moves from the retracted position of the slider 162. The rotation to the supply position is started. Furthermore, the cover 620 is rotated from the closed position toward the open position during the operation of the slider driving device 166, and the output signal of the photoelectric sensor 602 remains the OFF signal, but the output signal of the photoelectric sensor 604 is the ON signal. If it is detected that the cover 620 is positioned at the intermediate position, the operation of the slider driving device 166 is stopped. During the movement of the slider 162, at least the output signal of the photoelectric sensor 604 becomes an ON signal, and the operation of the slider driving device 166 is stopped by detecting that the cover 620 is opened more than the second set amount. . Both the output signals of the photoelectric sensors 602 and 604 are ON signals, and the operation of the slider driving device 166 is stopped by detecting that the cover 620 is opened more than the first set amount from the closed position. Good.
In this tray-type component supply device, the photoelectric sensor 602 constitutes an open detection device together with the dog 622, the photoelectric sensor 604 constitutes a close detection device together with the dog 622, and the photoelectric sensor 602.
604 constitutes an intermediate detection device together with the dog 622, and the dog 622 is shared by three detection devices. The photoelectric sensors 602, 604 and the dog 622 are open detection devices, closed detection devices, and intermediate detection devices. It can also be considered that it constitutes.

  The movable member may be moved by an air cylinder which is a kind of fluid pressure cylinder as a fluid pressure actuator. For example, as schematically shown in FIG. 15, the air cylinder 650 of the slider drive device 648 is not provided with a piston rod, and guides the movement of the pair of sliders 652 as movable members to the elevating member. A piston is engaged with a connecting member 656 that connects the pair of sliders 652 and is provided in parallel to the guide rail 654. A pair of sliders 652 are moved simultaneously by the movement of the piston, and are moved to a supply position and a retracted position. These positions are respectively defined by stoppers (not shown), and each of the supply position and the retracted position is Sensors 660 and 662 are provided in front of the small distance to detect the slider 652. The sensors 660 and 662 can be configured in various modes such as a photoelectric sensor. Each of the pair of sliders 652 is movably fitted to the guide rail 654 via a ball held so as to be circulated, and the movement is guided by a linear guide.

  The air cylinder 650 is a double-acting air cylinder, and each of the two pressure chambers is selectively communicated with the positive pressure source 672 and the atmosphere via an electromagnetic direction switching valve 670 as an electromagnetic control valve. Communication with both the source 672 and the atmosphere is interrupted. Further, normally open electromagnetic on / off valves 676 and 678 are provided in the passages connecting the two atmospheric pressure chambers to the electromagnetic direction switching valve 670, respectively, and bypass passages 680 and 682 bypassing the electromagnetic on / off valves 676 and 678. , And throttles 684 and 686 are provided in the bypass passages 680 and 682, respectively.

  The electromagnetic direction switching valve 670 and the electromagnetic opening / closing valves 676, 678 are controlled by the control device 690, and when the movement of the pair of sliders 652 located at the supply position to the retracted position is instructed, the electromagnetic direction switching valve 670 is switched. Of the two air pressure chambers of the air cylinder 650, air is supplied to the air pressure chamber on the side where the slider 652 is moved from the supply position to the retracted position, the other air pressure chamber is opened to the atmosphere, and the piston is moved to make a pair. The slider 652 is moved to the retracted position, and the support plate 692 is moved to the retracted position. At this time, the electromagnetic opening / closing valve 676 is opened, and air is supplied to the atmospheric pressure chamber without reducing the flow rate. Then, when the pair of sliders 652 move to the vicinity of the retracted position, the detection is made by the sensor 662, and the electromagnetic on-off valve 676 is closed based on the detection. As a result, air is supplied to the pressure chamber via the restrictor 684, the air supply flow rate (inflow amount) is reduced, and the slider 652 is decelerated. Then, the slider 652 abuts against a stopper (not shown) to define the movement limit, the arrival of the movement limit is detected by a sensor (not shown), and the supply of air to the atmospheric pressure chamber is stopped. The movement limit of the slider 652 may be defined by the stroke end of the piston, and the supply of air may be stopped.

When the pair of sliders 652 are moved from the retracted position to the supply position and the support plate 692 is moved to the supply position, the slider 652 is supplied from the retracted position by switching the electromagnetic direction switching valve 670. Air is supplied to the pressure chamber on the side to be moved to the position, and the other pressure chamber is opened to the atmosphere. When the slider 652 moves to the vicinity of the supply position and is detected by the sensor 660, the electromagnetic on-off valve 678 is closed, the supply flow rate of air to the atmospheric pressure chamber is reduced and reduced, and the pair of sliders 652 are decelerated. Is stopped. Even when the stop is instructed during the movement of the pair of sliders 652, the electromagnetic on-off valve 676 or 678 is closed, and the pair of sliders 652 are decelerated by reducing the air supply flow rate to the atmospheric pressure chamber.

  The ruler as a positioning member for positioning the tray may be T-shaped or I-shaped. Only one reference mark may be provided.

  Further, it is not indispensable to provide a positioning surface for positioning the positioning member in the Y-axis direction on the support plate. For example, a scale is provided on the support surface in both the X-axis direction and the Y-axis direction, and the mounting position of the positioning member is a scale The positioning member may be attached at the indicated position. Further, the tray may be supported on the support surface without using the positioning member. In this case, for example, the tray is restrained by a restraining member in four directions and fixed to the support plate, or the tray is held with a permanent magnet and fixed to the support plate by magnetic force.

Furthermore, the tray suction head is not limited to the one that sucks the tray by changing the positive pressure to the negative pressure, and may suck the tray by the negative pressure supplied from the negative pressure source.
Further, the support plate may be moved to the retracted position when the empty tray is discarded. In this case, it is not necessary to stop the movable member halfway between the supply position and the retracted position, and the control of the movable member by the movable member driving device is simplified.

  Further, at least one of the tray holding head and the height detection head may be provided on the Y-axis slide together with the component holding head. In this case, the Y-axis slide is provided with the same number of head holding devices and head lifting devices as the heads provided simultaneously, and each head is individually held and lifted.

For example, at least two head holding devices are provided on the movable member of the head moving device, and at least two types of work heads are simultaneously provided on the movable member and moved.

  Further, when the tray suction head and the component suction head are selectively held by the head holding device, the tray suction head can be rotated around the axis by the head rotation device, for example, the tray has a longitudinal shape. When the longitudinal direction is supported on the support plate in a posture parallel to the moving direction of the slider, the tray suction head sucks the tray and then rotates it so that the longitudinal direction of the tray is perpendicular to the moving direction of the slider. This reduces the length of the space occupied by the tray in the direction parallel to the slider movement direction, and the retraction distance from the support plate supply position (necessary to open the tray receiver for dropping the tray). A short distance), and the tray can be quickly discarded. The tray suction head may be rotated in parallel with the movement of the slider.

  The empty tray discarding device and the height detecting device may be moved by a dedicated moving device having a head holding device and moved up and down by a dedicated lifting device.

  Furthermore, the cover may be provided so as to be rotatable around the vertical axis, and may be moved to an open position and a closed position by linear movement. The linear moving direction is, for example, a horizontal direction, a direction parallel to the moving direction of the movable member, a direction perpendicular to the moving direction, or a vertical direction.

  Further, the tray receiver and the tray receiving device may be provided in a part of the component mounting system other than the position below the supply position of the movable member and the support plate.

  Furthermore, the support plate having a support surface capable of supporting a plurality of trays arranged horizontally may be directly fixed to the component mounting system, or may be detachably provided.

  Further, a computer may be provided in the tray-type component supply device to control the movable member driving device and manage the number of electronic circuit components accommodated in the tray, the supply number, the remaining number, and the like. In this case, when the tray-type component supply device is connected to the component mounting machine, the computer is connected to the control device of the component mounting machine, and, for example, data and instructions are exchanged by communication.
